Last year I built the platform 'Tindex'. It was an index of Tinder profiles so people could search by name, gender and age.
We scraped the Tinder profiles through a Tinder API which was discontinued not long ago, but weird enough it was still intact and one of my friends who was also working on it found out how to get api keys (somewhere in network tab at Tinder Online).
Except name, gender and age we also got 3 distances so we could calculate each users' location, then save the location each 15 minutes and put the coordinates on a map so users of Tindex could easily see the current location of a specific Tinder user.
Fun note: we also got the Spotify data of each Tinder user, so we could actually know on which time and which location a user listened to a specific Spotify track.
Later on we started building it out: A chatbot which connected to Tinder so Tindex users could automatically send a pick up line to their new matches (Was kinda buggy, sometimes it sent 3 pick up lines at ones).
Right when we started building a revenue model we stopped the entire project because a friend of ours had found out that we basically violated almost all terms.
Was a great project, learned a lot from it and actually had me thinking twice or more about online dating platforms.
Below an image of the user overview design I prototyped. The data is mock-data.

Its that time of the morning again where I get nothing done and moan about the past ... thats right its practiseSafeHex's most incompetent co-worker!!!
Today I'd like to tell you the story of "i". Interesting about "I" is that he was actually a colleague of yesterdays nominee "G" (and was present at the "java interface" video call, and agreed with G!): https://devrant.com/rants/1152317/...
"I" was the spearhead of a project to end all projects in that company. It was suppose to be a cross-platform thing but ended up only working for iOS. It was actually quite similar to this: https://jasonette.com/ (so similar i'm convinced G / I were part of this but I can't find their github ID's in it).
To briefly explain the above + what they built ... this is the worst piece of shit you can imagine ... and thats a pretty strong statement looking back at the rest of this series so far!
"I" thought this would solve all of our problems of having to build similar-ish apps for multiple customers by letting us re-use more code / UI across apps. His main solution, was every developers favourite part of writing code. I mean how often do you sit back and say:
"God damn I wish more of this development revolved around passing strings back and forth. Screw autocomplete, enums and typed classes / variables, I want more code / variables inside strings in this library!"
Yes thats right, the main part of this bullshittery was putting your entire app, into JSON, into a string and downloading it over http ... what could possibly go wrong!
Some of my issues were:
- Everything was a string, meaning we had no autocomplete. Every type and property had to be remembered and spelled perfectly.
- Everything was a string so we had no way to cmd + click / ctrl + click something to see somethings definition.
- Everything was a string so any business logic methods had to be remembered, all possible overloaded versions, no hints at param types no nothing.
- There was no specific tooling for any of this, it was literally open up xcode, create a json file and start writing strings.
- We couldn't use any of the native UI builders ... cause strings!
- We couldn't use any of the native UI layout constructs and we had to use these god awful custom layout managers, with a weird CSS feel to them.
What angered me a lot was their insistence that "You can download a new app over http and it will update instantly" ... except you can't because you can't download new business logic only UI. So its a new app, but must do 100% exactly the same thing as before.
His other achievements include:
- Deciding he didn't like apple's viewController and navigationBar classes and built his own, which was great when iOS 7 was released (changed the UI to allow drawing under the status bar) and we had no access to any of apples new code or methods, meaning everything had to be re-built from scratch.
- On my first week, my manager noticed he fucked up the login error handling on the app I was taking over. He noticed this as I was about to leave for the evening. I stayed so we could call him (he was in an earlier timezone). Rather than deal with his fucked up, he convinced the manager it would be a "great learning experience" for me to do it ... and stay in late ... while he goes home early.
- He once argued with me in front of the CEO, that his frankenstein cross-platform stuff was the right choice and that my way of using apples storyboards (and well thought out code) wasn't appropriate. So I challenged him to prove it, we got 2 clients who needed similar apps, we each did it our own way. He went 8 man weeks over, I came in 2 days under and his got slated in the app store for poor performance / issues. #result.
But rather than let it die he practically sucked off the CEO to let him improve the cross platform tooling instead.
... in that office you couldn't swing a cat without hitting a retard.
Having had to spend a lot more time working with him and more closely than most of the other nominees, at a minimum "I" is on the top of my list for needing a good punch in the face. Not for being an idiot (which he is), not for ruining so much (which he did), but for just being such an arrogant bastard about it all, despite constant failure.
Will "I" make it to most incompetent? Theres some pretty stiff competition so far
Tune in later for more practiceSafeHex's most incompetent co-worker!!!6 -
Summary: Burnout, and everything's broken.
I don't feel like doing a damn thing today. I look at the code and cringe. I look at Slack and think "ugh. i can't." Mental capitals are even too much work.
(I've started reading "Zen and the Art of Motorcycle Maintenance" to try and combat burnout. I'll write a rant/story about it here if I find it helpful. but all I want to do today is drink tea and read.)
But onto the story:
Heroku is deprecating support for and will automatically upgrade any old verisons of Postgres running on its platform after August something (like five days from now).
I performed the upgrade to PG10 on Sunday (and late into the night), provisioning a new follower, blah blah blah.
However, the version of Rails we're using (4.2.x) doesn't support PG10 sequences, so I manually added in support via a monkeypatch. I did this on our QA servers first, obviously, and everything worked as expected. After half a day of no issues, I did the same on production, and again: everything worked as expected.
But today? I keep hearing about new things that are broken. One specific type of alert doesn't work for one specific person (wat). Can't send [redacted] at all. Can't update merchants! Yet there are magically no errors logged.
That last one (well, two) are just great; let me explain: when there's an error concerning merchants, the error gets caught, isn't logged or recorded anywhere so it just disappears, and the rescue block triggers a json response instead and happily exits. This is for an internal admin tool, so returning a user-friendly error is kinda stupid anyway, but masking what actually happened? fuck that dev with an obelisk made from spikes and solidified pain. That json response is also lovely: it's a 200 OK returning {status: 1, data: "[generic message containing incorrect IT jargon]"}. Doesn't even say "error" anywhere. Bloody everything about this pattern is absolutely wrong. Even the friggin' text.
Fucking hell. I want to pipe the entire codebase into shred and walk out the door.
But I digress. So many things are broken, my motivation is wanning to a sliver, and I have a conference call today where I'll undoubtedly be asked why everything is on smoking and/or on fire, and my huge and overly productive week last week will ofc mean nothing by contrast.
Ugh.

I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...
#1 - Most expensive lesson learned
Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.
This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...
After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.
Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.
#2 - Hardest to find
This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.
Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.
#3 - Most elegant fix
Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.
My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.
So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.1 -
On my former job we once bought a competing company that was failing.
Not for the code but for their customers.
But to make the transition easy we needed to understand their code and database to make a migration script.
And that was a real deep dive.
Their system was built on top of a home grown platform intended to let customers design their own business flows which meant it contained solutions for forms and workflow path design. But that never hit of so instead they used their own platform to design a new system for a more specific purpose.
This required some extra functionality and had it been for their customers to use that functionality would have been added to the platform.
But since they had given up on that they took an easy route and started adding direct references between the code and the configuration.
That is, in the configuration they added explicit class names and method names to be used as data store or for actions.
This was of cause never documented in any way.
And it also was a big contributing cause to their downfall as they hit a complexity they could not handle.
Even the slightest change required synchronizing between the config in the db and the compiled code, which meant you could not see mistakes in compilation but only by trying out every form and action that touched what you changed.
And without documentation or search tools that also meant that no one new could work the code, you had to know what used what to make any changes.
Luckily for us we mostly only needed to understand the storage in the database but even that took about a month to map out WITH the help of their developer ;)
It was not only the “inner platform” it was abusing and breaking the inner platform in more was I can count.
If you are going down the inner platform, at least make sure you go all the way and build it as if it was for the customers, then you at least keep it consistent and keep a clear border between platform and how it is used.12 -
Help.
I'm a hardware guy. If I do software, it's bare-metal (almost always). I need to fully understand my build system and tweak it exactly to my needs. I'm the sorta guy that needs memory alignment and bitwise operations on a daily basis. I'm always cautious about processor cycles, memory allocation, and power consumption. I think twice if I really need to use a float there and I consider exactly what cost the abstraction layers I build come at.
I had done some web design and development, but that was back in the day when you knew all the workarounds for IE 5-7 by heart and when people were disappointed there wasn't going to be a XHTML 2.0. I didn't build anything large until recently.
Since that time, a lot has happened. Web development has evolved in a way I didn't really fancy, to say the least. Client-side rendering for everything the server could easily do? Of course. Wasting precious energy on mobile devices because it works well enough? Naturally. Solving the simplest problems with a gigantic mess of dependencies you don't even bother to inspect? Well, how else are you going to handle all your sensitive data?
I was going to compare this to the Arduino culture of using modules you don't understand in code you don't understand. But then again, you don't see consumer products or customer-specific electronics powered by an Arduino (at least not that I'm aware of).
I'm just not fit for that shooting-drills-at-walls methodology for getting holes. I'm not against neither easy nor pretty-to-look-at solutions, but it just comes across as wasteful for me nowadays.
So, after my hiatus from web development, I've now been in a sort of internet platform project for a few months. I'm now directly confronted with all that you guys love and hate, frontend frameworks and Node for the backend and whatever. I deliberately didn't voice my opinion when the stack was chosen, because I didn't want to interfere with the modern ways and instead get some experience out of it (and I am).
And now, I'm slowly starting to feel like it was OKAY to work like this.10 -
>>> Stadia thread <<<
Stadia is a new Cloud Gaming platform that runs on GCP and details were announced some minutes ago.
For maximum performance you would need at least 35mb/s, while about 10mb/s are enough for 720p l, Stereo gameplay.
Maximum performance provides 4k, HDR and 5.1 Surround Sound and comes in at 9,99$ / month for Stadia Pro. As far as announcements go, there are no lower performance tiers available.
Stadia Pro will get you unlimited access to your Games (I believe this is Bring-Your-Own-License, but I might be wrong), while Stadia Basic allows unlimited access to one specific game. For that you probably buy the game directly of Stadia, which then includes any fees in it's price.
Stadia will be usable on all devices that run Chrome and on the Chromecast Ultra. Android will get it's own app, first available on the Google Pixel 3, to be expanded later on, iOS was not mentioned.
Google developed a custom Stadia controller that works out of the box, including an Google Assistant and a DVR button. However, all other controllers should supported too, but I don't believe that's the case for playing on the Chromecast Ultra.
Starting now, you can get the Stadia Founders Edition, that allows you to be one of the firsts on the platform, includes a Controller, a Chromecast Ultra, 3 months of Stadia Pro, 3 additional months of Pro you can gift to your buddy and some Destiny Bundle with the first and second game, including all add-ons, plus the Destiny 2 Season pass.
The founders edition can be pre-ordered right now for about 129$.
Stadia launches 'later' this year, founders edition buyers will be the first to get public access on launch.8 -
Electron....
Ok so recently I have seen many people hating on electron like here https://medium.com/@caspervonb/... ...
I understand that it may not be efficient or native whatsoever but it has specific use cases in which it is ideal. For example Discord (a teamspeak/Skype for gamers) is an amazing platform and they used to be web based. Eventually people wanted a desktop app for all these platforms so they used electron. i have used discords desktop app for 5 months and NEVER have I seen it go over 1 gig of ram or 3% of my cpu.
Electron isnt bad it just has specific use cases. Its like NoSQL, it's awesome but not for everything.2 -

TL;DR Pluralsight should be ashamed for taking 299 USD a year and writing some very low-quality quizzes.
I've always heard that Pluralsight is a great platform having some high quality courses, so I chose it as a benefit, as our company was giving us some budget for learning purposes. I've paid (or rather the company did it in the end) 299 USD for this year, which, I guess is not much for US standards, but it is a lot for Eastern European standards.
I didn't actually get to the point of watching any of the courses, but I started to use a feature called "Stack up", which is a long series of questions in a specific theme, like Java, Kotlin, C++, etc., accessible once a day. I must say, I'm amazed by the fact, that people pay quite a great amount of money and they get something so poorly made with a lot of errors and stupid questions.
Take the question from the included image for example. Not only that the 2 possible answers are repeated (and thus I failed to select the correct one from 2 equal answers), but the supposedly correct answer is also missing some type specifications. No Java compiler will compile it this way as far as I know. There would be at least 3 ways to fix it.
Then there is today's gem (should be included as first comment) as well, where the answer is wrong in both Chrome 96, Firefox 95 and Node v10. Heck, THIS IS one of the reasons why you should never use `var` in your JavaScript code, but always `let` and `const`!
So the courses on Pluralsight might be good, but I would be ashamed, if I were to release something like this. People might actually try to solidify their knowledge by solving these quizzes but instead of learning something useful, they will be left with some bullshit. I just don't get how could they release a feature with so much incorrect information and I am kind of disappointed, even if I didn't try the courses yet.

Need some opinions. Joined a new company recently (yippee!!!). Just getting to grips with everything at the minute. I'm working on mobile and I will be setting up a new team to take over a project from a remote team. Looking at their iOS and Android code and they are using RxSwift and RxJava in them.
Don't know a whole lot about the Android space yet, but on iOS I did look into Reactive Cocoa at one point, and really didn't like it. Does anyone here use Rx, or have an opinion about them, good or bad? I can learn them myself, i'm not looking for help with that, i'm more interested in opinions on the tools themselves.
My initial view (with a lack of experience in the area):
- I'm not a huge fan of frameworks like this that attempt to change the entire flow or structure of a language / platform. I like using third party libraries, but to me, its excessive to include something like this rather than just learning the in's / out's of the platform. I think the reactive approach has its use cases and i'm not knocking the it all together. I just feel like this is a little bit of forcing a square peg into a round hole. Swift wasn't designed to work like that and a big layer will need to be added in, in order to change it. I would want to see tremendous gains in order to justify it, and frankly I don't see it compared to other approaches.
- I do like the MVVM approach included with it, but i've easily managed to do similar with a handful of protocols that didn't require a new architecture and approach.
- Not sure if this is an RxSwift thing, or just how its implemented here. But all ViewControllers need to be created by using a coordinator first. This really bugs me because it means changing everything again. When I first opened this app, login was being skipped, trying to add it back in by selecting the default storyboard gave me "unwrapping a nil optional" errors, which took a little while to figure out what was going on. This, to me, again is changing too much in the platform that even the basic launching of a screen now needs to be changed. It will be confusing while trying to build a new team who may or may not know the tech.
- I'm concerned about hiring new staff and having to make sure that they know this, can learn it or are even happy to do so.
- I'm concerned about having a decrease in the community size to debug issues. Had horrible experiences with this in the past with hybrid tech.
- I'm concerned with bugs being introduced or patterns being changed in the tool itself. Because it changes and touches everything, it will be a nightmare to rip it out or use something else and we'll be stuck with the issue. This seems to have happened with ReactiveCocoa where they made a change to their approach that seems to have caused a divide in the community, with people splitting off into other tech.
- In this app we have base Swift, with RxSwift and RxCocoa on top, with AlamoFire on top of that, with Moya on that and RxMoya on top again. This to me is too much when only looking at basic screens and networking. I would be concerned that moving to something more complex that we might end up with a tonne of dependencies.
- There seems to be issues with the server (nothing to do with RxSwift) but the errors seem to be getting caught by RxSwift and turned into very vague and difficult to debug console logs. "RxSwift.RxError error 4" is not great. Now again this could be a "way its being used" issue as oppose to an issue with RxSwift itself. But again were back to a big middle layer sitting between me and what I want to access. I've already had issues with login seeming to have 2 states, success or wrong password, meaning its not telling the user whats actually wrong. Now i'm not sure if this is bad dev or bad tools, but I get a sense RxSwift is contributing to it in some fashion, at least in this specific use of it.
I'll leave it there for now, any opinions or advice would be appreciated.18 -
procrastinating by getting drunk since 11:00 AM, and writing specs for my (hypothetical) language/os/platform.
feeling righteous retribution because the client made me be stressed for 3 hours due to an issue that THEY caused but for 3 hours the only info I had was "there's a critical blocker issue and we're convinced YOU caused it"
well... no... i did NOT cause the fact that you UPGRADED PHP DURING THE WEEKEND BEFORE MONDAY'S PRESENTATION TO CLIENT (while waiting for an urgent commit from me).
seriously.
also, germans. i've heard many times from other people that they're... basically racist towards us (slavic nations), thinking of us as untermensch, coal-miner peons, but I didn't realize their passive-aggressive covertly smug demanding attitude is due to this, I just assumed it's a reaction to me being incompetent.
so yesterday when we finished the call (in preparation for which I tried to switch to their "client demonstration" branch since that's where the error was, and I wanted a headstart on fixing it, ended up in a place that my today's whole-day task should be "rebuilding the DB into working condition", because there's about 10 "core" sql scripts in two different folders, which need to be run (in a very specific order, of course, which readme tells you, but what it tells you has been outdated at least for 3 months, of course), and
...THE MAIN CORE SCRIPT THAT IS THE FIRST TO RUN, THAT CREATES THE DB schema, HAS THREE SYNTAX-LEVEL typos which fail it mid-way...
...the joys of continuous deployment via scripts, I guess? I would love to challenge any person from them to screenshare to me, manual deployment of the current version from zero, and I would be willing to give the person 20% of my monthly salary if they would be able to do it within 20 minutes.
but... well...
the point is, i should be doing not entirely bullshit stuff.
but yesterday's 6 hours of being in "at full attention because it seems we fucked up" totally convinced me, that today I'm taking a break.
So I'm gonna go buy another 3 beers and continue writing the specs of my dream language/os/platform.19 -
I was working as a software dev contractor at this company providing specific e-learning services for a specific industry X.
One day the CEO posts on Linkedin about an interview discussing the potential of gaining $100k per year working in industry X after getting specialized training for 6 months (using our e-learning platform of course) .
My gross income at the time was $65k. My experience was about 7-8 years. Now the thing is you might say "gee that's pretty low for a dev, especially a contractor", and yes I agree, but you have to understand a few facts:
1. I am from eastern Europe (cheapish labor - which btw for all of you out there from the West, including Germany and whatnot, it is xenophobic to consider easterners cheap and it personally insults me and my ability - but that's another story)
2. I was happy to accept the offer since it was the best I had up to that point :))
Now, by the time the LinkedIn post I was heavily invested in the product development. I personally had written 30% of the code (frontend and backend) compared to the whole development team (about 15 devs)... and yes you might argue that performance is not measured by number of lines of code... but trust me when I am saying I did the most on that product, and I am not saying this to brag, I actually care about the stuff that I work on.
When I saw that post on Linkedin I thought to myself "what kind of BS is this? I am a dev and devs are supposedly the best paid workers out there, and a guy from industry X that just got trained for 6 months would get more than me?! WTF?!"
So I messaged the CEO ...
Me: I noticed the post from linkedin about $100k by working in industry X, I am curious how does one get to that revenue per year? What is your advice?
CEO: The best way to obtain value is by creating value which you maximize continuously.
Me: and how does one maximize value?
CEO: it does not matter how hard your work but how large of an impact you make!
Me: ... and how do you measure impact? (me thinking about performance reviews for contract negotiations - and because performance reviews should be SMART -> meaning it should be measurable somehow)
CEO: Simon Sinek says ... << insert motivational quote here because I don't remember and don't care >>
I just lost if after reading the name "Simon Sinek" ...
So you see my dear friends ? It is all fairy dust, smoke and mirrors, in the end it is about maximizing profits, lowering costs and maintaining the illusion of opportunity... when there is none.
Lord is my witness... I hate hypocrisy and quackery ...
You can imagine that my contribution on that product immediately lowered, doing the bare minimum to meet the contract demands AND I FEEL NO REGRET.
%&#$ YOU SIMON SINEK.4 -
One of my worst WFT moments was just over 2 years ago.
A former colleague had been tasked with “upgrading” our solution for handling customer specific CSS on our platform for building newsletter emails.
He had been with us for about 5 years and ported most of the front end gui over that time from classic asp to .net and C#.
This work started in November and with a pause over dec-mid jan for high season and Christmas leave he continued.
In the beginning if mars we had the first of multiple WTF on that when I realized that his solution required a lot of special CSS or rather LESS, more than the a actual HTML for the template, and all was custom less rules that was very hard to understand.
We found that he actually never really understood how LESS worked and had tried to do things in a very backward way. Another colleague jumped in and manage to clean it up a bit so it got down to manageable levels.
Then in the end of Mars came the next bigger WTF. This is a newsletter building application. Turns out the new LESS based solution was entirely dependent on the js version of LESS and only worked when running in the browser. Guess what, the email send engine is not a browser and css classes and rules generally does not work in emails.
The new solution was impossible to integrate with the part that built and sent the emails without some very heavy rework.
Oh, and it was also completely incompatible with 12 years of old newsletters and customer templates that just did not work.
And of cause, he had not shown any of this in code reviews but rather just merged it part by part to the new version branch interleaving it with 5 months of other work.
He left the company short after.11 -
can we all take a moment to appreciate the developers of flutter. they're smart, and they took the time to make flutter the *right* way.
they used an easy to learn language that's ideal for mobile development, which means hot reload/restart is possible (because dart supports aot and jit compilation)
the way it's designed is beautiful. everything is a widget, and it's easy to customize them via named parameters.
the community is great. it's not large, but it's supportive, with two active subreddits. yesterday i asked a question on r/flutterdev, and a member of the flutter team at google answered the question with a comprehensive answer.
flutter is very consistent across platforms. if it works on android or ios, you can bet it'll work on the other just as well, with the exception of platform-specific code.
it is VERY performant. unless you write a major bottleneck, 60fps is easy to achieve.
animations are EASY. define a tween and animation controller and then write a callback function. not to mention it's straightforward, and complex/combined animations are easy, too.
you can get almost direct access to the canvas, should you need it, with custompainter.
oh my god, this is revolutionary in the programming world. development is quicker than it is with native android alone, and for people who have no access to a mac, like me, i can develop for ios and compile via code magic. if you haven't checked it out and you develop for mobile, check it out.
oh yeah, did i mention it's not just mobile. hummingbird - flutter compiled to web - is already in experimental public betas, and will likely be released by the end of the year. there's also experimental desktop support, which is amazing, and much better than electron. not to mention flutter is the future, as it will be the primary way to make apps on fuchsia os.13 -
I just felt like Google is the best player out there in terms of Companies.
Seriously, Well played Google.
This is not a negative opinion, I am just awe-struck at its tactics.
See, Google is currently the biggest name in terms of development in Android, ML and multi-platform software but no one can say it being a monopoly due to its dedication to open source community.
Recently Android emerged out to be One of the Biggest , most advanced, trusted and loved Technology . It saw great achievements, and up till 2016-17, it was at its peek. BUT when the market started shifting towards multi-platform boons and Ai, it got its hands into that too with its flutter and kotlin environment
One could have a negative opinion about this, But i can't seem to engulf the vast amounts of positive situations i see in this:
1) this IO18 (and many months before that) saw ML/AI being incorporated in Android (also the arcore, proje tango and many more attempts in the past) meaning that Android will not officially "die". It will just become an extremely encouraged platform( not just limited to mobiles) and a beginning of the robot -human reality ( a mobile is handling everything of your everyday life: chats, music apps sxhedules, alarms, and with an actively interacting ML, it won't be long when Android comes installed in a green bug lime droid robot serving you tea xD). Meanwhile the market of Windows games may shift to mobiles or typically " Android games" (remember, Android won't be limited to mobiles)
2)java may or may not die. The animations and smooth flow it seems to provide is always appreciated but kotlin seems to do so too. As for the hard-core apps, they are usually written in c++ .So java is in the red zone
3) kotlin-native and Flutter will be the weapons of future , for sure. they will be developing multi-platform softwares and will be dividing the market of softwares into platform specific softwares(having better ml/ai interactions,animations) and platform independent apps(access and use anywhere softwares).
And where does google stand?Its the lord varys of game of thrones which just supports and enhances the people in the realm. So it benefits the most . That's a company for you, ladies and gentlemen! If seen from common eyes they seem to be the best company ever and our 1 true king but it can also be a very thick fur cloak hiding their negetive policies and tactics , if any.

Figured I'd post for some advice here and see if anybody has had previous experience or success with a situation like this.
My team is generally comprised of full-stack developers completing front-end custom work on sites, writing back-end tools, and fixing broken sites. We are a rapid-response DEV team, and we typically turn around any custom requests in less than 5 days and fix any broken sites on the same day as they were reported. We manage almost 15,000 sites across multiple countries, and deal with very large corporations that many of you interact with every day (I'm trying to be cryptic here hahaha.) There are 16 of us on our team, and we are the only DEV team within our department of 500+ people. We are also the only DEV team taking requests from these 500+ people. The way the department works, we are the final say on whether a specific piece of custom work will get completed or not, and we are the go-to people when anybody has a question about our system infrastructure or if our system can accommodate a request, along with how to fix any broken pieces of our platform. We typically get about 150 requests per day. Lately, the entire team has become unhappy with our compensation for the work we do. We're quite underpaid, and they keep giving us more responsibilities without any sort of extra compensation. We've discovered that there are a large amount of non-developers below us that are getting paid more than we are. We've found that we get paid about $15,000 less than a comparable DEV team in a different department (let's call that team DEV_2,) just because of which department our team exists within, and how our department defined our job back when this position was created a few years ago. Ever since the position was created, our team's responsibilities have exponentially increased. We believe that there is absolutely no reason that an entry-level position below us should get paid just as much, or even more in some cases, than a developer. Of course, we're not asking to pay them less. Instead, we've decided that we're going to bring this up with our manager and schedule a meeting with him, our Department Director, and Human Resources, and voice that we believe that we should be on the same payscale as the comparable DEV_2 in the other department.
To be a good developer on our team, you need to not only have coding expertise, but also an encyclopedic knowledge of what you can do within our platform without any coding. You need this knowledge so you can pass it along to any people in positions below you, in case they didn't know that something could be done without custom code.
We're going to argue that if it weren't for our team, the company would be losing millions of dollars in clients, because people wouldn't have anybody to go to for platform infrastructure questions, broken websites, or custom work. Instead, they would need to send these requests to the DEV_2 team, which currently take about 6 months to turnaround requests. Like I said, we are a rapid-response DEV team, and these particular clients think that a 5 day turnaround time is ridiculous. If they had to wait 6 months for their request to be completed, they would cancel their contracts.
Not to mention the general loss of knowledge if the members of our team went to a different department, which would be catastrophic for our current department. Believe me, this department could not function without this DEV team. If we all went on vacation for a week, the place would be on fire by the time we got back, and many clients would be lost.
Do any of you have any experience with a situation like this, and if so, how did it turn out? Thank you!5 -
Applications written with game engines - Unity to be specific -, that mimick usual user interfaces with an appalling design that screams "grefic desein is ma peaetion"

I just finished designing an entire asset management pipeline and christ on a fucking pogo stick, if it isn't convoluted.
Theres a lot of game engines out there, but all of them do it a little different. They all tackle a slightly different problem, without even realizing it.
1. asset management
2. asset change management
3. behavior change management
4. data management
5. combinatorial design management.
6. Combinatorial Behavior management
7. Feature completion
ASSET MANAGEMENT is exactly what it says on the tin.
ASSET CHANGE management can be thought of handling the import, export, formatting, platform specific packing, and versioning (including forking) of an asset.
BEHAVIORAL CHANGE management is a subset of asset management, because code is a subset of assets (depending on how you define 'assets'). The oldest known example of this is commenting and uncommenting code.
Or worse, printf debugging.
This can be file versioning, basic undo services, graph management of forks and mergers, toggles for features or modules, etc.
DATA management is about anything that doesn't fall into the other categories, everything from mission text to npc dialogues, quests, location names, item stats, the works. Anything you'd be tempted to put in a database, falls under this category. Haven't yet seen many engines offer this as an explicit built in tool as of yet, because the other problems are non-trivial as is, so this is a bit of low hanging fruit that gets handled by external tools, or loaded from formats as simple as json.
COMBINATORIAL DESIGN management is the idea of prefabbing, blueprints of broader object design using nested prototypes of existing game objects, to create more complex, reusable set pieces. Unity did this well. GM does this in part.
COMBINATORIAL BEHAVIOR management is entity-component systems, plus tooling to make it easy to add, remove, and configure components and their values on entity blueprints, also not uncommon. Both stencyl and unity do this. GM has a precursor to this in the form of configurable fields, but these fields are not based on component scripts attached to objects.
FEATURE COMPLETION is that set of gameplay mechanics or styles of design that an engine naturally makes easier to include or build in a game.
I don't think I'm aiming for all that, but I think at minimum a good engine has to do asset management, behavioral change management, prefabs, and entity-component systems with management tools for that. And ideally, asset change management.8 -
Seriously, fuck Discord's new community guidelines! They now think they even own you outside of ther shady app:
"We may consider relevant off-platform behavior when assessing for violations of specific Community Guidelines."
Addressing harmful off-plattform behavior:
https://discord.com/blog/...
"When we talk about off-platform behaviors, we’re referring to any behaviors taking place outside of Discord, either in other digital spaces or in a physical community. If we become aware of specific off-platform, high-harm behaviors with credible evidence committed by a person with a Discord account, we will take the off-platform harmful behavior into consideration when assessing whether that account has violated a specific Community Guideline."
"We are applying this off-platform behavior consideration only if we become aware of highest-harm threats, including using Discord for organizing, promoting, or supporting violent extremism; making threats of violence; and sexualizing children in any way."
Yeah, suure...

A week with flutter:
1. I like how simple it is compared to React Native
2. Same issues as react, want platform specific, good luck writing plugins. Though the upside is I can use Swift and Kotlin with it, but still mixed code is bad7 -
C++99, C++03, C++11 and C++14
I love when your design finally ends up working, looks good and it's running as fast as Usain Bolt, but why the hell does OOP has to be so ugly and clunky in C++? Constructors and copy constructors designs are barf inducing. Yes I am trying to make it as readable and neat as possible but it still looks like shit overall. And related compiler errors are almost always retarded or unhelpful even though I'm used to it now.
I know you will tell me "why are you using those old ass versions?". Well unfortunately in embedded you are stuck with old crap until some envoy of the gods finally up the standards... or if I do it myself for a specific platform.2 -

How do you (not) secure your Rest based web service?
1. Chain it to shady organic authentication system built by a hoard of monkeys high on Tequila.
2. have secret keys that get copy pasted into config flat files, and index them on your code search engine.
3. make the onboarding extremely platform specific that you need 500 environment variables, 50 scripts, 5 fancy device presses and a tap dance to make a GET call to the service.
4. fish through 500 rotating log files that the authentication system generates for each API call made.
5. Leave traces all over the host so if you have to start over, you should sudo rm -rf / and set fire to your computer. -
One thing JS does great is that everything from the server to the gui to the (extremely flexible) build system is 100% platform independent with very few platform specific bugs. And that's a big deal when a basic setup is 1200 packages from 650+ semi-coordinated people.13

Looking for platform specific language options for a new project at work and reading articles from well known sources.
If you start your article with something like, "when I think of a good programming language, I think of JavaScript", I'm going to punch out of your shitty opinion faster than an async function.
When you're trying to convey an unbiased message you generally don't start with, "I'm an absolute shill for {language}".
What the fuck happened to journalistic integrity?7 -
We had a issue with a webstore that was only affecting users on Windows: one button didn't do anything.
The colleague that was working on the ticket was running Arch, and for him it was working as expected. He reported that the bug couldn't be replicated on Chromium, Firefox or qutebrowser. But our designer, who was running Windows 10, commented that it wasn't working for her in either Chrome or Firefox.
Some more conflicting reports later a colleague using Windows managed to fix it. It was caused by querying the button elements by id selector instead or a class selector. There was multple buttons, one for each product row.
I guess there just are platform differences that aren't specific to browser but instead the OS, that could have caused it7 -

This is more of a thought-related post. In the morning I stumbled across an article about artificial intelligence and the research from Facebook. I couldn't get around the thought of Elon Musk warning the people about uncontrolled developing of AI. The article was written about the experiment of Facebook, where two bots (Bob and Alice) were told to communicate with each other. As the developers "forgot" to implement a reward for using the English language, the bots started to change the grammar and spelling. They invented their own english-styled language, removing words that were too complex in their opinion. As soon as this happened, the researchers stopped the experiment, stating that they "couldn't follow what the bots were saying".
I wouldn't call myself a neural network expert, but I can understand why the bots could have behaved like that. But: Imagine that we invent an artificial intelligence with greater responsibility and just "forget" the reward for a specific task. If the AI will then try to increase it's own efficiency, I believe that we will be in alot of trouble.
Any thoughts on this are highly appreciated, as I think that this is a topic we should all look into (especially on a platform for developers).

I'm sure this has been ranted about before because I can hardly be the only one.
Android development and the upgrade dance.
Things were worse in the bad old days of eclipse but it's not like they're peachy now, either. Android is one of many platforms I'm developing for - c++ back-end, running on lots of different platforms through a thin bit of platform specific glue.
That's all I care about - that this thin bit of glue just works. I want to write this stuff, forget about it and get on with solving what I feel are real problems, for me, in my code.
The trouble is, I'm never finished writing this and android is one of the worst. With every revision change, google changes *something*. New build system? Why not, you indie developers have *loads* of time and resources to waste on that, don't you? Some weird thing just stops working for no apparent reason? You guys love to drop whatever it was you were working on to figure out what the hell ' android.app.Instrumentation' does and why it can't talk to my main class any more, or why I even need it but nothing in that error message about what I might do to fix this arcane random error.
Google have all the resources in the world, I do not. Yet I have to dance for them, every time I upgrade.
Can you guys please funnel some of your practically infinite resources in to making this stuff 'just work'? -
The Zen Of Ripping Off Airtable:
(patterned after The Zen Of Python. For all those shamelessly copying airtables basic functionality)
*Columns can be *reordered* for visual priority and ease of use.
* Rows are purely presentational, and mostly for grouping and formatting.
* Data cells are objects in their own right, so they can control their own rendering, and formatting.
* Columns (as objects) are where linkages and other column specific data are stored.
* Rows (as objects) are where row specific data (full-row formatting) are stored.
* Rows are views or references *into* columns which hold references to the actual data cells
* Tables are meant for managing and structuring *small* amounts of data (less than 10k rows) per table.
* Just as you might do "=A1:A5" to reference a cell range in google or excel, you might do "opt(table1:columnN)" in a column header to create a 'type' for the cells in that column.
* An enumeration is a table with a single column, useful for doing the equivalent of airtables options and tags. You will never be able to decide if it should be stored on a specific column, on a specific table for ease of reuse, or separately where it and its brothers will visually clutter your list of tables. Take a shot if you are here.
* Typing or linking a column should be accomplishable first through a command-driven type language, held in column headers and cells as text.
* Take a shot if you somehow ended up creating any of the following: an FSM, a custom regex parser, a new programming language.
* A good structuring system gives us options or tags (multiple select), selections (single select), and many other datatypes and should be first, programmatically available through a simple command-driven language like how commands are done in datacells in excel or google sheets.
* Columns are a means to organize data cells, and set constraints and formatting on an entire range.
* Row height, can be overridden by the settings of a cell. If a cell overrides the row and column render/graphics settings, then it must be drawn last--drawing over the default grid.
* The header of a column is itself a datacell.
* Columns have no order among themselves. Order is purely presentational, and stored on the table itself.
* The last statement is because this allows us to pluck individual columns out of tables for specialized views.
*Very* fast scrolling on large datasets, with row and cell height variability is complicated. Thinking about it makes me want to drink. You should drink too before you embark on implementing it.
* Wherever possible, don't use a database.
If you're thinking about using a database, see the previous koan.
* If you use a database, expect to pick and choose among column-oriented stores, and json, while factoring for platform support, api support, whether you want your front-end users to be forced to install and setup a full database,
and if not, what file-based .so or .dll database engine is out there that also supports video, audio, images, and custom types.
* For each time you ignore one of these nuggets of wisdom, take a shot, question your sanity, quit halfway, and then write another koan about what you learned.
* If you do not have liquor on hand, for each time you would take a shot, spank yourself on the ass. For those who think this is a reward, for each time you would spank yourself on the ass, instead *don't* spank yourself on the ass.
* Take a sip if you *definitely* wildly misused terms from OOP, MVP, and spreadsheets.5 -
I often wonder why JS is the only language that has the native support from browsers and native built in DOM apis?
The world has come up to a saturation point for so many techs:
- if a software is needed to be created for mobile, it must go through 1 layer of java (aka JVM) or objective C (i guess? for ios) before being understood by the CPU
- if a software is needed to be run via browser( which itself is made to run on jvm, objective c or machine language), it must go through one layer of js interpretters before being understood by the CPU
all the OS are made on C but the application and application platforms are made on specific languages. I wonder why can't there be a single application platform, if all of them(browser, JVM,objective C and whatever .exe apps run on) are doing the same thing and are equally mature to handle every usecase?13 -
Who actually started the reign of mixed character passwords? because seriously it sucks to have an unnecessarily complex password! Like websites and apps requesting passwords to contain Upper/Lower case letter, numeric characters and symbols without considering the average user with low memory threshold (i.e; Me).
Let's push the complaint aside and return back to the actual reason a complex password is required.
Like we already know; Passwords are made complex so it can't be easily guessed by password crackers used by hackers and the primary reason behind adding symbols and numbers in a password is simply to create a stretch for possible outcome of guesses.
Now let's take a look into the logic behind a password cracker.
To hack a password,
1) The Password Cracker will usually lookup a dictionary of passwords (This point is very necessary for any possible outcome).
2) Attempts to login multiple times with list of passwords found (In most cases successful entries are found for passwords less than 8 chars).
3) If none was successful after the end of the dictionary, the cracker formulates each password on the dictionary to match popular standards of most website (i.e; First letter uppercase, a number at the end followed by a symbol. Thanks to those websites!)
4) If any password was successful, the cracker adds them to a new dictionary called a "pattern builder list" (This gives the cracker an upper edge on that specific platform because most websites forces a specific password pattern anyway)
In comparison:
>> Mygirlfriend98##
would be cracked faster compared to
>> iloveburberryihatepeanuts
Why?
Because the former is short and follows a popular pattern.
In reality, password crackers don't specifically care about Upper-Lowercase-Number-Symbol bullshit! They care more about the length of the password, the pattern of the password and formerly used entries (either from keyloggers or from previously hacked passwords).
So the need for requesting a humanly complex password is totally unnecessary because it's a bot that is being dealt with not another human.
My devrant password is a short story of *how I met first girlfriend* Goodluck to a password cracker!6 -
So I was looking into phone app development again (as you do) and I'm working on a simple QoL app for me and my SO that will help us automate some home management and finances stuff. Naturally I delved down the rabbit hole deep and wanted to have push notifications so we don't have to check the app periodically to know when certain things happen... Oh boy... Why is mobile development so convoluted, especially if you don't want to rely on Google Services...
It seems that the most accepted way of doing this is Firebase (FCM). Well me being me, I refuse to use google services for this and I prefer self hosted solutions (for data privacy reasons) which eliminates most products out there.
It also didn't help that my framework of choice is Flutter/Dart, because fuck Android Studio and the insane buggy XML stuff and fuck Android and it's constantly changing APIs...
Well In the end I decided on a rather simple solution and self hosted an AMQP service (RabbitMQ in my case, as I have some experience with it already) and implemented a foreground service in android platform specific code on top of my flutter project to kickstart it and made my phone a queue listener... This now means I can push notifications from my server to the Messaging Queue and it will be pushed into my App automatically!
One thing I found out on this journey was that Android now kills most background services and enforces foreground services to have a visible notification in the status drawer... which I actually approve of. It's a bit annoying that you can start a reliable background service, but I'm absolutely on-board with long running processes started by my apps are constantly visible...
Long story short, I love reinventing all the wheels, especially if it's for free and private... And I also went to sleep at 2AM again because this took longer that I'd like to tune... but it works, and it's google free...
I'm thinking of trying to package this up as a flutter module later, but first I want to do testing on battery life and the general life cycle of the service. RabbitMQ says they have the client library optimized for long-lasting connections and it should be just using a tcp socket, which should pretty much be what all the push notification services are doing anyway. I'm also not completely satisfied with how the permanent notification looks.. it isn't collapsible like some of the other ones from other apps and it's about 2 lines high instead of single line... which is something quite annoying and I'm struggling to find any relevant docs on how this is done other than possible making a custom Notification Style... but I just can't believe that everyone is doing that.. there must be a built-in somewhere -_-... Ugh Android is hell...
Anyway, if any android devs here have some hints, tips and tricks on how to handle this type of background/foreground process stuff and I'm doing something wrong let me know, cause googling this shit is a nightmare too!6 -
One of these days i'm gonna pop a blood vessel, trying to keep all my dotfiles organized: syncing the files themselves is easy, just shove them into git, the problem is that i have to install dependencies on different distros (Arch, Debian and Ubuntu):
The package names are different, the paths are different, fuck with Debian i need to compile from source anyway because most of the packages i need aren't available. Its taking me so much time writing distro-specific installers, just so i can deploy my setup on different machines...
Its at times like these that you appreciate just how mind-boggling fragmented Linux is as a platform :D8 -
Couldn't be arsed with all the conditional compilation that angelscript required, so I dumped right back to good ol' lua for now.
Got lua in, vm started, loading strings and pushing/popping the stack.
Got SDL actually drawing as intended.
I don't know even half of what I'm doing.
Apparently header files that end in ".hpp" are specific to c++, while .h are for c headers.
I like the new SDL2 though, little bit different than SDL1. Not a lot of tutorials cover the difference, but I could kinda suss out from the documentation where I needed to adapt, even though I'm still pretty loose on the library, on the docs, and on c++ itself.
Still just a learning project.
Also, I'm continually surprised there isn't a portable, platform independent tool or little language just for replacing all pseudo-languages out there like .bat and .sh, and .zsh
Maybe even just a tool that standardizes it all, then takes config files that map the new standard to system dependant commands, so you can download the damn thing, configure the relevant environment variables, drop in the platform dependent configuration (or your browser or package tool detects what platform you are on and chooses the relevant package/download for your platform), write a console script and the tool automatically translates, and emits the system-relevant commands to that platform's console (so you don't even need much platform-specific code to do things like file access). -
PM: Could you make a deployment platform to only roll out to specific users, and make a script that changes the code so that you can tailor tasks to each user.
Me: Excuse me? ... -
As a developer, how important to you that you have the choice of tools/platforms to do your job?
I've worked on some companies that don't give a damn as long as you get the job done, while some frown upon it because they haven't tried anything other than what they have and are skeptical. Some are completely locked because their products are platform specific so it makes sense for dev to work on the same platform.
Thoughts?5 -
Why do I keep getting an error when posting my rant saying, "There was an error creating the rant."?
Has anyone else gotten this before? Happening both on mobile app, mobile browser, and laptop's browser so it's not the platform.

Was absent minded this whole day, sorry if my answers took long / were out of context @ the meetup.
I was poking why a bona fide DB import didn't work...
VARCHAR(254) COLLATE utf8_unicode_ci GENERATED ALWAYS AS (LOWER(...)) VIRTUAL
MySQL 5.7 to MariaDb 10.5 ...
After long hours of poking:
https://jira.mariadb.org/browse/...
Yeah. It's the COLLATE statement. *narf*
I love SQL, but god damn it this stupid fscking frigging dumb platform and version specific behaviour is fucking annoying.
sed -Ei 's|COLLATE.*GENERATED|GENERATED|g' helps. Just takes a bit of time on an 75G sql dump. -.-
Took only 4.5 hours to find out.
But now test suites are crunching, looking good til now.... *sigh*2 -
So. Wow I have a question. Ok for real... I am in need of advice. I have a concept for a platform based on a specific interest which almost all of us have, based on a peer-to-peer principle with multiple services and user types/needs/agendas/reasons. The platform is intellectually straight forward and users will all participate on the platform as they see fit which will benefit other users as well as motivate more to join. The platform will serve it's own purpose and meet the users needs in a way that you may have seen before but the intellectual property and how the platform is used, is so unique that I can't risk too much information.
The question is. How do I protect my idea / intellectual property so I can recruit help and market without someone coming along and stealing it out from underneath me?
This isn't uncle Vinnys Cologne idea...
Everyone thinks they have the million dollar winner. I'm not sure if this puts gold toilet paper in my bathroom just yet but... I have something that an existing platform with money will absolutely steal and try to push as their own idea... They will probably succeed too.
So how do I protect this from happening so only I get to fail or ruin this good idea?1 -
It baffles me that although all they're doing is shuffling numbers around based on abstract descriptions of the target architecture and platform-specific behavior is completely out of the question, compilers are some of the least portable programs in active development.
-
You know what I dont like? Platform specific propriety softwares...
Oh well, there is always a better open source alternative1 -
I first try to figure out why I really want to build this and (if the project is intended that way) why someone would use it.
Then I strip the idea down to its bare minimums so I know what I should build for it to be of any value.
And then I start building until I no longer think it's worth working on the project.
For instance:
I am kind of surprised to see that in a world where cloud and apis become more and more leading, there isn't really a commonly accepted and flexible api management platform.
There are some cloud based platforms out there that can be configured using some interface but why is it like that? Surely you aren't going to deploy multiple versions of your core with different platforms right?
That's where my latest project comes in. I want to create an on-prem api management platform which you configure to work with your api during development. Then you can deploy it to any infrastructure alongside your core api.
This way you:
- are not bound to a specific cloud
- don't have to worry about security and firewalls
- get user management and rate limiting for free
I will probably create a collab for this once the platform is mature enough.1 -
TLDR; Anybody got a good method of running multiple terminals with one command without tmux or something like that?
So I've got a lot of projects where I need multiple terminals running at the same time. Might be a backend + frontend application or something that's just split into multiple smaller applications. I usually just start multiple terminals and enter the commands to start the specific sub-application in each of them, but that's tedious, and developers are lazy.
I've tried making something nice with tmux, but I've found it to be a bit too cumbersome. Let's say I need to restart an application. Two interrupts and I've stopped one of four panes. And it's not very intuitive for beginners, and more often than not there are other developers involved.
Any suggestions on a good way to run multiple commands/applications at the same time, preferably with a single command? It has to work cross-platform as well as I work with Linux, Mac and Windows users.8 -
I have a doubt regarding blockchain. I understand how it works, but couldnot make use of it.
I am currently working on a platform which let client to assign task to their employee
Now I am planning to make use of blockchain on existing platform, to somehow set up a mechanism to authenticate that employee had completed the task, as a certification to the employee. I just cannot figure out how
I thought of an implementation, ( if its possible ) where client will trigger the smart contract with some employee-specific data, and the smart contract will generate a custom token, which will then be sent to the employee's account. This token will be non transferable1 -
I have a platform idea, I need feedback
Problem statement: it’s hard to find researchers of specific area, which discourages students to even start looking for research opportunities. The reason for that is because people often look into their own academic circle, and the resource available is simply not enough.
Solution: by scraping Google scholar, generate detailed tag of sub areas for each professors, make a search system for that which will display the most important works of a researcher and what they are working on recently. If possible, invite the researchers to use the platform to add tags of traits they are looking for in students.
I have quite polarized feedback right now, one is the subarea tagging is really useful and academic circle is a problem, other is this is completely useless.
Please let me know what you think.3 -
So I'm target multiple platforms with one of my c++ projects and on one of the platforms I the window manager is quite different, and one of the libraries can't be used. Thats fine for my needs, I'm just wondering what the typical way to allow for these differences is. Basically currently I've created 2 "main" files that have preprocessor code to only use he one that's right for the platform by having ifdefs at the beginning of each, I've kinda followed that methodology for the other files that are totally platform specific also. Is there a better way to go about this? Currently using msvc for windows compilation and a gcc-esqu compiler for one of the other platforms, where the compile command is built by a home made build tool.

Why in the fuck does everyone expose specific ports in Dockerfiles?
If I wanted to expose the port, I would fucking expose it.
Currently can't run my home infra platform because I'm running two separate instances of Maria DB on the same private internal network. These are two databases for two separate applications.
Why don't I run them on one? Because they're two separate fucking applications.
Why the fuck can I not do this when I used to be able to do it a week ago.
Stop exposing your fucking ports in your fucking Dockerfiles.
This shit is getting so bad, I'm just about to throw my towel in on all fucking containers and just install everything in multiple VM environments.
I am God damn appalled that after 8 years of using docker, core concepts like a port exposure is being leveraged as a way to somehow circumvent poor security practices.
You want a secure container environment? Expose your own goddamn ports.
Fuck you Maria DB, and fuck you docker.2 -
which is the best cloud provider for a complete beginner (user/dev) in terms of community support, employer preference and user-friendliness?
i know that understanding the tech and concepts behind it matters more than getting familiarized with a specific platform, but i'm looking to build a more diverse profile and have noticed many positions asking for AWS/Azure experience.
since i'll be starting from scratch, any provider with easy-to-follow documentation, online help and certifications that don't leave you broke (would have to pay myself, earn very less as a student from a third-world country, parents/current employer can't support) would work.8
