Good Morning!, its time for practiseSafeHex's most incompetent co-worker!
Todays contestant is a very special one.
*sitcom audience: WHY?*
Glad you asked, you see if you were to look at his linkedin profile, you would see a job title unlike any you've seen before.
*sitcom audience oooooooohhhhhh*
were not talking software developer, engineer, tech lead, designer, CTO, CEO or anything like that, No No our new entrant "G" surpasses all of those with the title ..... "Software extraordinaire".
*sitcom audience laughs hysterically*
I KNOW!, wtf does that even mean! as a previous dev-ranter pointed out does this mean he IS quality code? I'd say he's more like a trash can ... where his code belongs
*ba dum tsssss*
Ok ok, lets get on with the show, heres some reasons why "G" is on the show:
One of G's tasks was to build an analytics gathering library for iOS, similar to google analytics where you track pages and events (we couldn't use google's). G was SO good at this job he implemented 2 features we didn't even ask for:
- If the library was unable to load its config file (for any reason) it would throw an uncatchable system integrity error, crashing the app.
- If anything was passed into any of the functions that wasn't expected (null, empty array etc.) it would crash the app as it was "more efficient" to not do any sanity checks inside the library.
This caused a lot of issues as some of the data needed to come from the clients server. The day we launched the app, within the first 3 hours we had over 40k crash logs and a VERY angry client.
Now, what makes this story important is not the bugs themselves, come on how many times have we all done something stupid? No the issue here was G defended all of this as the right thing to do!
.. and no he wasn't stoned or drunk!
G claimed if he couldn't get the right settings / params he wouldn't be able to track the event and then our CEO wouldn't have our usage data. To which I replied:
"So your solution was to not give the client an app instead? ... which also doesn't give the CEO his data".
He got very angry and asked me "what would you do then?". I offered a solution something like why not have a default tag for "error" or "unknown" where if theres an issue, we send up whatever we have, plus the file name and store it somewhere else. I was told I was being ridiculous as it wasn't built to track anything like that and that would never work ... his solution? ... pull the library out of the app and forget it.
... once again giving everyone no data.
G later moved onto another cross-platform style project. Backend team were particularly unhappy as they got no spec of what needed to be done. All they knew was it was a single endpoint dealing with very complex model. There was no Java classes, super classes, abstract classes or even interfaces, just this huge chunk of mocked data. So myself and the lead sat down with him, and asked where the interfaces for the backend where, or designs / architecture for them etc.
His response, to this day frightens me ... not makes me angry, not bewilders me ... scares the living shit out of me that people like this exist in the world and have successful careers.
G: "hhhmmm, I know how to build an interface, but i've never understood them ... Like lets say I have an interface, what now? how does that help me in any way? I can't physically use it, does it not just use up time building it for no reason?"
us: "... ... how are the backend team suppose to understand the model, its types, integrate it into the other systems?"
G: "Can I not just tell them and they can write it down?"
**
I'll just pause here for a moment, as you'll likely need to read that again out of sheer disbelief
**
I've never seen someone die inside the way the lead did. He started a syllable and his face just dropped, eyes glazed over and he instantly lost all the will to live. He replied:
" wel ............... it doesn't matter ... its not important ... I have to go, good luck with the project"
*killed the screen share and left the room*
now I know you are all dying in suspense to know what happened to that project, I can drop the shocking bombshell that it was in fact cancelled. Thankfully only ~350 man hours were spent on it
... yep, not a typo.
G's crowning achievement however will go down in history. VERY long story short, backend got deployed to the server and EVERYTHING broke. Lead investigated, found mistakes and config issues on every second line, load balancer wasn't even starting up. When asked had this been tested before it was deployed:
G: "Yeah I tested it on my machine, it worked fine"
lead: "... and on the server?"
G: "no, my machine will do the same thing"
lead: "do you have a load balancer and multiple VM's?"
G: "no, but Java is Java"
... and with that its time to end todays episode. Will G be our most incompetent? ... maybe.
Tune in later for more practiceSafeHex's most incompetent co-worker!!!31 -
Got an email from a stakeholder about a $0 transaction for an item that was not meant to be $0. Found someone put a condition in the code to set the price to $0 if it couldn’t be queried from the database. Wut…that is…not logical 😵💫😵9

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
School gave me 3 DigitalOcean droplets to try out Kubernetes in the cloud, awesome!
Wrote an Ansible script to not only simply install docker and add users but also add kubernetes, nice!
Oh wait, error?! Well I should've known this wasn't going to be easy... ah well no problem. Let's see... Ansible is cryptic as always, it can't connect to the API server? Is it even running?
Let's ssh to the master, ah nothing is running, great. Let's try out kubeadm init and see what happens, oh gosh, my Docker version has not been validated! No problem, let's just downgrade!
How do I do that? Oh I know, change the version in the role! Wait that version doesn't exit? Let's travel to Docker's website and see what versions exist of docker-ce, oh I see, it needs a subversion, no problem.
Oh that errors too? Wait then what... Oh I need a ~ and a ubuntu and a 0 somewhere, my mistake!
Let's run it again! Fails!
Same ssh process, oh wait...
Oh god no...
Kubernetes requires 2 cores and these things only have 1...
Welp, time to ask the teachers to resize my droplet by a small amount tomorrow, hopefully I'll get a new error!
----------------------------------------------
My adventure so far with Kubernetes. I'm not installing it for any serious/prod reason, just for educational purposes. K8s seems like 'endgame' to me, like one of the 'big guys' that big enterprises use so I'm eager to throw stuff at a droplet and see what happens.
Going further down the rabbit hole tomorrow!
Wish me luck :3
(And yes, I could've figured this all out beforehand with documentation, but this is more fun in my opinion)8 -
I am currently looking for a DAW (Digital Audio Workstation), because my music projects are starting to get a little too complex for Audacity.
So I started looking for a good, easy-to-learn, ideally free program, and quickly learned that Avid now has a free version of Pro Tools called First.
So I go to their site and fill out the registration form to get the download. In addition to creating an account with Avid, you also need to create one with iLok, which apparently has something to do with how they manage their licenses. Kinda overkill for a free program, but okay...
I download the program (about 3gigs...), install it and try to start it. It gives me an error message about missing some service. Okay? I'm confused because I notice that an 'Application Manager' service has appeared in my tray, and when I open that I can log into my new account just fine. But it still doesn't work.
There's a link in the error message to the iLok website, and it looks like ai need to dowload and install another component. Why didn't that get installed with the program if it's required?
Hmm...
So I go to the iLok site, download it and install it. Pro Tools First still won't start. I realize that the PTF installer asked me to reboot, which I didn't do because: a) I always have a lot of windows open, and b) How often is a reboot ACTUALLY required? Why would you need to reboot?
So I (begrudgingly) reboot, and now the program seems to start initializing... but then it throws an error message about some plugin that it can't load because it doesn't work for the 64 bit version. Then... why are you even looking for it?
And then it says something like: 'I can't handle that, I'm just gonna shut down'.
What?
I try starting it again. Same error appears, but then it gets past it this time... Only to throw another error message about something else it can't load, and therefore it must shut down.
Deep breath.
Third time is the charm, the program actually made it to the project create/load screen! Huzzah!
So I look around a bit, but don't do much. It doesn't seem too intuitive to me, so I start watching some tutorials on YouTube from Avid themselves. It's a little late by now, so I don't get my hands dirty that day.
Next time I want to try out the program I start it up, still get error messages, but it does seem to initialize okay. But then the 'Create project' button doesn't react when I press it.
It turns out that the program takes a looong time to log in to the avid account, even though the manager service is running and logged in...
When it finally logs on I create a new blank project, but it doesn't ask me where to save it to. I see there is a counter saying 1/3 and looking around I find some info about 'cloud based projects'.
It would seem that this program only supports saving projects to the cloud, and you get only 3 projects total. Three. THREE?
Ahem...
I add an instrument track to my new project and select the one and only plugin, which is a synth. I don't see the plugin window, like in the tutorials I watched. I fiddle around with the windows, but I only manage to get the layout fucked up. There's a handy 'Window' menu, but none of the options resets the view. The main window is now sporting a WINDOWS FUCKING 7 BORDER! And partially blocking the view of the top menu.
Blaaargh!
Frustrated, I shut the program down and restart it. I now select one of the project templates (after waiting for it to LOG IN AGAIN!) in the hope that I might have a bit more luck with that starting point.
But when the template has loaded, out of nowhere, the program goes from maximized to windowed mode! And the fucking Win7 border is back again, still messing with the main menu!
FFS!
I get the sucker maximized again and select one of the synth tracks, and Lo and Behold! The synth plugin window actually shows up! But of course there is no sound produced when I play, neither with the keyboard or my midi keyboard.
Oh no, that would have been too easy.
I see some the meters moving when I play, but no sound is produced. I check the options menu, but find out nothing useful except for the fact that the program only support 48kHz sample rate. That's pretty disappointing when you have a 192kHz/24bit soundcard.
I'm done. This piece of shit software is NOT for me. It's bloated, complicated to sign up for and install, extremely limited and buggy as hell!
The final insult is that it takes 5 minutes to uninstall because there is no uninstall option in the so-called 'Application Manager' (of course fucking not!), and doing it through Programs & Features there are 5 (FIVE!!) different apps and services to uninstall, one by one.
0/10, would not recommend.11 -
OK people, I don't need a novel written for every line of code, but PLEASE STOP trying to tell me that "yOuR coDe sHouLd bE sELf dOcUmeNtiNg aNd cOmMenTs mEaN iT's aUtoMaTiCaLLy bAd". That's a bunch of BS. I can't begin to tell you how many times I've saved my own butt by dropping a "this call can't be awaited; causes the library's internal API to throw an error" comment in my C#, or a "can't use double quotes here; doesn't work right for some reason" line in my JavaScript. Sometimes there are very good but un-obvious reasons why something was done a certain way, even though it looks like it could be done better. And don't try to tell me "the tests will catch it". Let's be realistic here, nobody has 100% test coverage on any project that's much more than "Hello World". And even if the tests DID catch it, why waste the time when you could just write a comment?
P.S.: This is not directed at anyone on here specifically. It's directed at all the devs I've met IRL and the comments I've seen on SO, who think that comments must be bad.12 -
Come on guys, use those JSON schemas properly. The number of times I see people going "err, few strings here, any other properties ok, no properties required, job done." Dahhh, that's pointless. Lock that bloody thing down as much as you possibly can.
I mean, the damn things can be used to fail fast whenever you misspell properties, miss required properties, format dates wrong - heck, even when you want to validate the set format of an array - and then libraries will throw back an error to your client (or logs if you're just on backend) and tell you *exactly what's wrong.* It's immensely powerful, and all you have to do is craft a decent schema to get it for free.
If I see one more person trying to validate their JSON manually in 500 lines of buggy code and throwing ambiguous error messages when it could have been trivially handled by a schema, I'm going to scream.18 -
python machine learning tutorials:
- import preprocessed dataset in perfect format specially crafted to match the model instead of reading from file like an actual real life would work
- use images data for recurrent neural network and see no problem
- use Conv1D for 2d input data like images
- use two letter variable names that only tutorial creator knows what they mean.
- do 10 data transformation in 1 line with no explanation of what is going on
- just enter these magic words
- okey guys thanks for watching make sure to hit that subscribe button
ehh, the machine learning ecosystem is burning pile of shit let me give you some examples:
- thanks to years of object oriented programming research and most wonderful abstractions we have "loss.backward()" which have no apparent connection to model but it affects the model, good to know
- cannot install the python packages because python must be >= 3.9 and at the same time < 3.9
- runtime error with bullshit cryptic message
- python having no data types but pytorch forces you to specify float32
- lets throw away the module name of a function with these simple tricks:
"import torch.nn.functional as F"
"import torch_geometric.transforms as T"
- tensor.detach().cpu().numpy() ???
- class NeuralNetwork(torch.nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__() ????
- lets call a function that switches on the tracking of math operations on tensors "model.train()" instead of something more indicative of the function actual effect like "model.set_mode_to_train()"
- what the fuck is ".iloc" ?
- solving environment -/- brings back memories when you could make a breakfast while the computer was turning on
- hey lets choose the slowest, most sloppy and inconsistent language ever created for high performance computing task called "data sCieNcE". but.. but. you can use numpy! I DONT GIVE A SHIT about numpy why don't you motherfuckers create a language that is inherently performant instead of calling some convoluted c++ library that requires 10s of dependencies? Why don't you create a package management system that works without me having to try random bullshit for 3 hours???
- lets set as industry standard a jupyter notebook which is not git compatible and have either 2 second latency of tab completion, no tab completion, no documentation on hover or useless documentation on hover, no way to easily redo the changes, no autosave, no error highlighting and possibility to use variable defined in a cell below in the cell above it
- lets use inconsistent variable names like "read_csv" and "isfile"
- lets pass a boolean variable as a string "true"
- lets contribute to tech enabled authoritarianism and create a face recognition and object detection models that china uses to destroy uyghur minority
- lets create a license plate computer vision system that will help government surveillance everyone, guys what a great idea
I don't want to deal with this bullshit language, bullshit ecosystem and bullshit unethical tech anymore.11 -
Of course, I just swiped the wrong way on my fucking laptop trackpad and list everything I just typed. FUCKING MARVELOUS.
TL;DR: Teacher stopped me from being productive. Principal almost called cops on me. Nearly threw chair at librarian.
So I'm at school yesterday, and we have a presenter in 2nd hour, so naturally, I'm gonna be on my computer doing things for other classes at the same time. Efficiency. Teacher doesn't like it, I refuse to put the computer away telling her that I'll be more productive and still pay attention, which HAS BEEN PROVEN MIND YOU, but she ends up calling security on me and I get sent down to the principal's office.
I talk to him, and he says 'Yeah, I know it's in the way, but you have to follow the directive given by the teachers.' Fine, fuck it. Won't go to her class for third hour. (I have her twice in a row for two different classes.) Next day.
I walk in, asking her if she's gonna do the same thing she did yesterday, hoping that she realized her error and will fix it, but no. She says I STILL can't have the computer out. I'm sorry, do you not realize I have 6 other fucking classes, most of which are required to graduate, unlike YOURS, as well as a FUCKING COLLEGE CLASS TONIGHT?! She gives the ultimatum. 'Obey or leave.' Fine, I'll leave. I go to the principal's office again, he must have a stick up his ass or something today because he's not budging. We argue for a while and he gives a WORSE ultimatum: 'Obey, Go to the Library, In House Suspension, or I'll call the police.' What the actual FUCK MAN?! You're gonna call the POLICE on a NONVIOLENT STUDENT?! Are you fucking MAD? I keep trying to tell him that there's an easy solution to this, but as he's getting up to call the cops, I say 'Fine! I'll go to the library!' He follows me over to make sure I don't kill anyone on the way.
I slam the door to the library open, and when I walk in, the librarian is there at her computer, and she asks 'Where are you coming from?' 'Principal!' 'I need a pass-' 'Well, I'm sorry, I can't exactly get anything for you right now, I was just sent down here.' She says 'Either way, I need some kind of note or pas-' 'Listen, I'm not in the mood for any of this right now. Please, just leave me be.' She then tries to say something, but I cut her off quickly, 'Just back off and leave me alone right now. The more you push it, the more you're gonna make me want to throw this chair!' Imagine the volume just gradually getting louder on that last one. She quickly runs out and talks to the security desk or something, which is right outside the library door, but she's the only one who comes in, thankfully. I was expecting to be fucking dragged out for no good reason. I'm loud, not violent. I have no history of violence.
So yeah. Here I am in the school library, angrily tapping away at my keyboard, trying not to throw the entire table to the fucking moon. All because this broken-ass public school system has no idea how to deviate from the norm when it's actually productive and efficient to do so. And now, the obligatory:
FUCKING PIECES OF SHIT WHY DON'T YOU REALIZE THAT YOU ARE COMPLETELY WRONG IN EVERY SINGLE THING YOU ARE DOING YOU IDIOTIC SCUM-FILLED MEAT SACKS OF NO FORSEEABLE VALUE! FUCK!1 -
XCode you fucking piece of shit...
So I just wanted to process my ios app to the app store and start the archive process. All of the sudden:
Command CodeSign failed with a nonzero exit code
What? So there is an error and you cannot tell me the error code? All information you give me that it isn't zero!? Wow... Amazing... What a great user experience. Maybe it cannot resolve the error? Maybe it is some external tool Apple has no access to and that is the only valid error they can throw at us?
Oh hell no! It has something to do with the keychain access! But why tell the user? That wouldn't be as much fun as just tell it is a nonzero error, isn't it apple?!
In the end locking and unlocking my key chain solved the problem... Thanks for nothing XCode!2 -
I did not think that making a serverless Discord bot would be such a learning experience. The code itself was easy. The hard part was the infrastructure, because I decided to automate it all with Terraform and deploy it on AWS.
Before this project, I had no idea how API Gateways worked. Now I still have very little idea how they work but I managed to build one anyway. Eventually. And then I had to figure out how to automate the deployment of a lambda layer and function that would both still be managed in the Terraform state, with any code changes triggering a rebuild and update for the resource.
And then I had to untangle a dependency mess because API Gateways have some weird issues where two resources that have no explicit dependencies on each other will throw an error if they don't deploy in the right order.
And then I went the wrong way with Github actions trying to conditionally chain multiple workflows together before I realized I could just put multiple jobs with conditions in a single workflow.
And now after all that work over the course of 2 days, I have a bot that does this:2 -
Had to extend the platform of a customer. For one part of my task (generating an encrypted string) there already was a class with encryption and decryption methods. This class is used in a gazillion places all over the code, so I thought it might be a good idea to re-use already existing stuff... Until I saw that the encryption method using basic Java methods (all fine with that) wrapped in a try-catch block, 'cause the Java methods may throw, returning err.getMessage() in the catch block...
Yeah...sure...makes sense... Instead of throwing an error or returning null just remove the possibility to handle the error.
So I decided to basically copy the methods and return null so I can work with that.
Created a merge request and was told by another dev of that company to remove my own impelemtation of the encryption method and use the already existing. Arguing that I won't have a possibility to prevent my code, that returns an URI containing the encrypted string, from generating something like "http://..../Encryption failed because of null" without success.
So I had to use the already existing crappy code...5 -
The worst part about switching code from python 2 to python 3:
`map(myfunc, mylist)`, behaves differently, but won't throw an error. It will just show up as nothing.3 -
Let me rant! I don’t usually do this but this is just frustrating and draining. Please tell me if im wrong. We have authentication that needs to be refactored. I was assigned on this issue. Im a junior btw. I also attached an image of my proposals. The issue of the old way of our signup process is that when validation fails they will keep on accepting the TaC (terms and conditions) and on our create method we have the validation and creating the user. Basically if User.create(user_params) create else throw invalid end. (Imma take a photo later and show it you)which needs to be refactored. So I created a proposal 1. On my first proposal I could create a middleware to check if the body is correct or valid if its valid show the TaCs and if they accept thats the moment the user is created. There is also additional delete user because DoE told me that we dont need middlewares we have before and after hooks! (I wanted to puke here clearly he doesn’t understand the request and response cycle and separation of concerns) anyway, so if middleware is not accepted then i have to delete the user if they dont accept the TaCs. Proposal 2. If they dont want me to touch the create method i could just show the TaCs and if they dont accept then redirect if they do then show form and do the sign process.
This whats weird (weird because he has a lot of experience and has master or phd) he proposes to create a method called validate (this method is in the same controller as the create, i think hes thinking about hooks) call it first and if it fails then response with error and dont save user, heres the a weird part again he wants me to manually check on each entity. Like User.find_by_email(bs@g.com) something like that and on my mind wtf. Isnt it the same as User.create(user_params) because this will return false if paras are invalid?? (I might be wrong here)
This is not the first time though He proposes solutions that are complex, inefficient, unmaintainable. And i think he doesnt understand ruby on rails or webdev in particular. This the first time i complained or I never complained because im thinking im just a junior and he hs more experience and has a higher degree. This is mot the case here though. I guess not all person who has a higher degree are right. To all self thought and bachelors im telling you not all people who went to prestige university and has a higher degree are correct and right all the time. Anyway ill continue later and do what he says. Let me know if im wrong please. Thanks4 -
I just spent a few hours wondering why Android Studio wouldn't recognize my phone. I later found out that it was set to "Use same device for future launches", but as i never used a device before it just didn't have a standard device and decided to just throw me an error instead of asking me to select a device. Yeah, Android Studio is great

FUCK YOUUUU media creation tool! Should have created a bootable stick, but NO, it does not just throw an error and leave my stick without any partition anymore, it even JUST THROWS AWAY the downloaded file...couln't have saved it as iso, no?!
Jeez, after taking over an hour for downloading5 -
try{
If(!res || typeof res == undefined || res == undefined){}
}catch(err){
// you just had to throw an error

Urgh... No exceptions in Rust annoys me. Now you only have the choice between "this didn't work please handle this error, thank you ^-^" and "you fool, prepare for annihilation". So basically if anything remotely serious happens your programs dead and there's nothing you can do about it. I don't get why people have this hate for exceptions. Everytime a new language gets made it's always either "ew it has exceptions" or "it's so nice it doesn't even have exceptions". NOOO! They can deal with serious situations in the best possible way and they can be statically checked (so no "but they're so complex and unpredicable" stuff please). If you can expect an exception they shouldn't be used in the first place (eventhough they are absolutely no less good than Option returntypes or whatever, just different) but in cases when it's impossible to predict an error they really shine. And not having them makes your language worse. If a device driver accesses illegal memory it should throw an exception, so instead of the computer shitting the bed, first the offending function has a chance to resolve the problem at it's root, then a few functions up the call stack, the general control functions of the device drivers can handle it and restart the operation if applicable, and even if the driver fails to handle it, the OS can jump in and restart the driver, log an error and do whatever. It's absolutely beautiful: This hierarchical ramp from near the accident site to more high level operations code ensures the error can be caught at the right level of abstraction without introduction a lot of boilerplate. If everything fails and nobody can handle it *then* the program or kernel or whatever can panic.4

AHHHHHHHHHHGGGH
I HATE VPN SETUP
- Trying OpenSwan
Installing open swan on a Debian machine.. setting up the config.
Restarting openswan. Syntax error. No syntax error to be found.
Different tutorial.. it starts! Try to connect.. I can’t connect. Look at the logs. No errors.
Tcpdump. My traffic is coming through.. all fine.. try to connect again.. it works! (Nothing changed!)
Try to ping somewhere else.. no connectivity.
Try to ping an IP in the same network.. works fine. So I have connectivity, just no internet.
Spend an hour finding out about traffic directions of which no one seems to know what they really mean.
Boss tells me to stop using openswan because it’s deprecated and replaced by strong swan..
- Strongswan
Reinstall Debian machine, install strongswan. Copy openswan config. Oh, they’re incompatible? Look up strong swan config, and the service starts.
Connect to the VPN.. it works! Again, no internet, just connectivity in the same network. Spend 2h debugging the config, disable firewalls everywhere, find an ancient bug in the Debian package related to my issues.. ok, let’s try compiling from source.. you know what, let’s not. I’ll throw this Debian machine away and try something completely different.
- pfSense
Ok, this looks easy enough! Let’s just click through the initial setup, change some firewall rules, create an L2TP VPN with a simple wizard.
Try to connect to VPN. First, it times out. Maybe a firewall issue? Turn off firewall.. ah, something happens now. I get an error message right after trying to connect to the VPN. Hmm, the port doesn’t even get opened when I enable the firewall.. this implementation seems a bit buggy.. let’s try their OpenVPN module.
Configure OpenVPN. Documentation isn’t that clear.. apparently a client isn’t actually a client but a user is a client.. ok, there’s a hidden checkbox somewhere.
Now where do I download my certificate? Oh, I need a plug-in for that.. ok, interesting. Able to download the certificate, import it, connect and.. YES!!! I can ping! But, I have no DNS..
Apparently, ICMP isn’t getting filtered but all outbound ports are.. yet the firewall is completely disabled. Maybe I need outbound NAT? Oh. There’s no clear documentation on where to configure it. Find some ancient doc, set it up, still no outbound connectivity.
AHAHAHAHHHHHHHHHHG
Then I tried VyOS. I had a great L2TP VPN working in less than 15 mins. Thank you VyOS for actually providing proper docs and proper software.3 -
(Warning, wall of text)
Settle an argument for me. Say you have a system that deals with proprietary .foo files. And there are multiple versions of foo files. And your system has to identify which version of foo you are using and validate the data accordingly.
Now the project I was on had a FooValidator class that would take a foo file, validate the data and either throw an error or send the data on its merry way through the rest of the system. A coworker of mine argued that this was terrible practice because all of the foo container classes should just contain a validate method. I argued that it was a design choice and not bad practice just different practice. But I have also read that rather than a design choice that having a FooValidator is the right way to do OOP. Opinions?1 -
I love it!
So I want to understand an new library, to get rid of some functions that are expected to cause some trouble in our main product. Luckily someone did a great job on github, providing a programm that can do what I want in a slightly different, more complicated way. But it is good and we need it anyway.
But instead of understanding the things I wanted to learn, somehow my test programm just didnt work. It just didnt want to. I DID EVERYTHING THE SAME I ALWAYS DID. Without implementing anything new. And it didnt throw any error, debugging showed me what i already knew, BUT NOTHING HAPPEND.
Wasted the day, tried everything, learned nothing.
BTW its written in C, so my error is definitely some tiny dumb shit, that i was too stupid to see... -
TypeScript types are fun. Problem is: the check is compile-time only.
I just wasted an hour not understanding that an integer passed from command line was actually getting transmitted as a string. The library, where that value landed as parameter, happily ignored the non-matching type and worked as if the value has not been set at all!
Dear library maintainer, please enforce your parameter types! Throw an error right into my face saying I shall not pass anything but an integer! Don't just continue to work to produce false output correctly. Thank you!
Dear TypeScript, I really want type checks on runtime.
Dear JavaScript: Why did you ever think loose types were a good idea? (And I say that as a PHP developer as well.)2 -
firstly, does anyone know of an online telegram or whatsapp group where i can ask silly stuff regarding web dev and get immediate answers, just like it is here?
secondly i am trying to learn js and there are just too many related terms that are messing with my brain:
"some features are supported ines5/es6/es15/es16/es17 , some are supported in chrome's v8/chakra/spidermonkey/android browser , some features are only supported in "serverside" and blocked in all browsers thanks to browser's vm environment; babel can't read this code, some features are provided only by node js..."
WHAT THE MESS IS THIS?
All i am trying to do is to write code that would make a website visible to everyone. if by specific browser , i want to target, chrome and its subsidaries and android chrome/other android browsers .
for other browsers am willing to make external converters later but don't want to change my code by 1 bit. And from what i know, each browser (at least the browsers am thinking of supporting) has the complete JS compilers already built in
can i or can i not built a complete functional website with those things?
and finally my main question : how to make custom exceptions in vanilla js? i saw this answer on stack overflow:
===================
function InvalidArgumentException(message) {
this.message = message;
// Use V8's native method if available, otherwise fallback
if ("captureStackTrace" in Error)
Error.captureStackTrace(this, InvalidArgumentException);
else
this.stack = (new Error()).stack;
}
InvalidArgumentException.prototype = Object.create(Error.prototype);
InvalidArgumentException.prototype.name = "InvalidArgumentException";
InvalidArgumentException.prototype.constructor = InvalidArgumentException;
Usage:
throw new InvalidArgumentException();
var err = new InvalidArgumentException("Not yet...");
=====================================
where is the error code? what would be the exception details? what is the line number/timestamp of error?why is that function making an error, i thought error/exception is a class in JS?4 -
Just discovered https://twitter.com/ExpertBeginner1. It's the story of my life. Giant classes, copying and pasting, and architects who create frameworks. It's great when we combine all three: A "framework" created by an architect which is made of giant classes that you copy and paste. Imagine a giant generic class where the generic argument is only used by dead code. Pause for a moment and try to visualize that.
It inherits from a base class with lots of virtual methods called by base methods that throw NotImplementedException, so if you don't need them you have to override them to return empty collections. If you're going to do something so messed up you could just put those default implementations in the base. But no, you can inherit, it compiles, and then it throws a runtime error unless you override methods the compiler doesn't require you to override.
The one method you're required to override has a TODO comment telling you what to put there. Except don't ever do what the comment says because that's the old standard. The new standard says never, ever do that.
Most of the time when I read about copy-and-paste coding it's about devs who copy and paste because they don't know how to write or reuse code. They don't mention the environments where copying and pasting the same classes over and over again is the requirement and you're not allowed to write your own code.
Creating base classes where you just override a method or two can potentially work, but only in the right scenarios and only if you do it right. If you're copying and pasting a class that inherits from the base class and consists entirely of repeated code, why the heck isn't that the base class? It could be a total mess, but at least it would be out of sight and each successive developer wouldn't become responsible for it by including it in their own code.
It's a temporary engagement, but I feel almost violated. I know it's a first-world problem, and I get to work indoors and take vacations. I'm grateful for those things.
Before leaving I had to document the entire process of copying and pasting an entire repo, making a ton of baseline edits that should just be in the template but aren't, and then copying and pasting from other places into the copied and pasted code. That makes me a collaborator. I apologize more than once in the documentation, all 20 pages of it that you have to read and follow before you even get to the part where you write the code for what you actually need it to do.
This architect has succeeded in making every single thing anyone does more about servicing the needs of his "framework" than about writing actual code to do what needs doing. Now that the framework is in and around everything it creates the illusion that it's a critical part of our operations. It's not. It's useless overhead.
Because management is deceived into thinking they need it they overlook the fact that it blows up, big and small, every single day. The log is full of failures that I know no one ever sees. A big chunk of what they think it does fails silently, and they don't even notice until months later when they realize how much data they're missing. But if they lose, say, 25% they'll never notice.
When they do notice they just act like it's normal, go into fire drill mode, and fix it. Doom. You're all doomed. I'm standing on the deck of the Titanic next to my jet ski.1 -
Is developing on Windows equivalent to squaring the circle? Yeah, obligatory windows bad circlejerk I know.
I’ve been developing a QT5 application for 2 weeks now on my main Linux system. Now, I wanted to make a Windows port for my friends to try.
I install QtCreator on Windows since it’s what I used on Linux. First time setup, I was forced to create an account; I was kind of pissed off but no biggie, I just put “Fuck you” on every credential possible. That’ll teach em.
Now, I needed a decent compiler. Visual Studio is a no go because why the fuck is it so big; also last I checked this thing barely supports C99. So I went with MinGW64 and MSYS2 and made a kit of it. I also went with that because it was the easiest way to get the latest version of GSL and MathGL without having to compile it. Also, the fact that MSYS2 had pacman was pretty nice.
I couldn’t get the thing to work for the whole day until I realized that my kit was pointing to the wrong compiler, turns out msys64/mingw64/bin/g++ and msys64/usr/bin/g++ are two different things. Ok whatever
Now, I just need to hunt down all the .a files and throw it in the LIBS option to get the libraries to work.
I finally made a successful build. Only to find that the application did absolutely nothing. I went with copy pasting the dlls into where the exe was located and launching it manually only to find the error “Application could not start correctly”
Yeah, I might be a retard but fuck you Windows. All I had to do on linux was just install qtcreator on my package manager and let the library dependencies be handled automatically and I could start doing my work right away.6
