So a few days ago I felt pretty h*ckin professional.
I'm an intern and my job was to get the last 2003 server off the racks (It's a government job, so it's a wonder we only have one 2003 server left). The problem being that the service running on that server cannot just be placed on a new OS. It's some custom engineering document server that was built in 2003 on a 1995 tech stack and it had been abandoned for so long that it was apparently lost to time with no hope of recovery.
"Please redesign the system. Use a modern tech stack. Have at it, she's your project, do as you wish."
Music to my ears.
First challenge is getting the data off the old server. It's a 1995 .mdb file, so the most recent version of Access that would be able to open it is 2010.
Option two: There's an "export" button that literally just vomits all 16,644 records into a tab-delimited text file. Since this option didn't require scavenging up an old version of Access, I wrote a Python script to just read the export file.
And something like 30% of the records were invalid. Why? Well, one of the fields allowed for newline characters. This was an issue because records were separated by newline. So any record with a field containing newline became invalid.
Although, this did not stop me. Not even close. I figured it out and fixed it in about 10 minutes. All records read into the program without issue.
Next for designing the database. My stack is MySQL and NodeJS, which my supervisors approved of. There was a lot of data that looked like it would fit into an integer, but one or two odd records would have something like "1050b" which mean that just a few items prevented me from having as slick of a database design as I wanted. I designed the tables, about 18 columns per record, mostly varchar(64).
Next challenge was putting the exported data into the database. At first I thought of doing it record by record from my python script. Connect to the MySQL server and just iterate over all the data I had. But what I ended up actually doing was generating a .sql file and running that on the server. This took a few tries thanks to a lot of inconsistencies in the data, but eventually, I got all 16k records in the new database and I had never been so happy.
The next two hours were very productive, designing a front end which was very clean. I had just enough time to design a rough prototype that works totally off ajax requests. I want to keep it that way so that other services can contact this data, as it may be useful to have an engineering data API.
Anyways, that was my win story of the week. I was handed a challenge; an old, decaying server full of important data, and despite the hitches one might expect from archaic data, I was able to rescue every byte. I will probably be presenting my prototype to the higher ups in Engineering sometime this week.

Not one feature.
All analytics systems in general.
Whether it's implementing some tracking script, or building a custom backend for it.
So called "growth hackers" will hate me for this, but I find the results from analytics tools absolutely useless.
I don't subscribe to this whole "data driven" way of doing things, because when you dig down, the data is almost always wrong.
We removed a table view in favor of a tile overview because the majority seemed to use it. Small detail: The tiles were default (bias!), and the table didn't render well on mobile, but when speaking to users they told us they actually liked the table better — we just had to fix it.
Nokia almost went under because of this. Their analytics tools showed them that people loved solid dependable feature phones and hated the slow as fuck smartphones with bad touchscreens — the reality was that people hated details about smartphones, but loved the concept.
Analytics are biased.
They tell dangerous lies.
Did you really have zero Android/Firefox users, or do those users use blocking extensions?
Did people really like page B, or was A's design better except for the incessant crashing?
If a feature increased signups, did you also look at churn? Did you just create a bait marketing campaign with a sudden peak which scares away loyal customers?
The opinions and feelings of users are not objective and easily classifiable, they're fuzzy and detailed with lots of asterisks.
Invite 10 random people to use your product in exchange for a gift coupon, and film them interacting & commenting on usability.
I promise you, those ten people will provide better data than your JS snippet can drag out of a million users.
This talk is pretty great, go watch it:

We're using a ticket system at work that a local company wrote specifically for IT-support companies. It's missing so many (to us) essential features that they flat out ignored the feature requests for. I started dissecting their front-end code to find ways to get the site to do what we want and find a lot of ugly code.
Stuff like if(!confirm("blablabla") == false) and whole JavaScript libraries just to perform one task in one page that are loaded on every page you visit, complaining in the js console that they are loaded in the wrong order. It also uses a websocket on a completely arbitrary port making it impossible to work with it if you are on a restricted wifi. They flat out lie about their customers not wanting an offline app even though their communications platform on which they got asked this question once again got swarmed with big customers disagreeing as the mobile perofrmance and design of the mobile webpage is just atrocious.
So i dig farther and farthee adding all the features we want into a userscript with a beat little 'custom namespace' i make pretty good progress until i find a site that does asynchronous loading of its subpages all of a sudden. They never do that anywhere else. Injecting code into the overcomolicated jQuery mess that they call code is impossible to me, so i track changes via a mutationObserver (awesome stuff for userscripts, never heard of it before) and get that running too.
The userscript got such a volume of functions in such a short time that my boss even used it to demonstrate to them what we want and asked them why they couldn't do it in a reasonable timeframe.
All in all I'm pretty proud if the script, but i hate that software companies that write such a mess of code in different coding styles all over the place even get a foot into the door.
And that's just the code part: They very veeeery often just break stuff in updates that then require multiple hotfixes throughout the day after we complain about it. These errors even go so far to break functionality completely or just throw 500s in our face. It really gives you the impression that they are not testing that thing at all.
And the worst: They actively encourage their trainees to write as much code as possible to get paid more than their contract says, so of course they just break stuff all the time to write as much as possible.
Where did i get that information you ask? They state it on ther fucking career page!
We also have reverse proxy in front of that page that manages the HTTPS encryption and Let's Encrypt renewal. Guess what: They internally check if the certificate on the machine is valid and the system refuses to work if it isn't. How do you upload a certificate to the system you asked? You don't! You have to mail it to them for them to SSH into the system and install it manually. When will that be possible you ask? SOON™.
At least after a while i got them to just disable the 'feature'.
While we are at 'features' (sorry for the bad structure): They have this genius 'smart redirect' feature that is supposed to throw you right back where you were once you're done editing something. Brilliant idea, how do they do it? Using a callback libk like everyone else? Noooo. A serverside database entry that only gets correctly updated half of the time. So while multitasking in multiple tabs because the performance of that thing almost forces you to makes it a whole lot worse you are not protected from it if you don't. Example: you did work on ticket A and save that. You get redirected to ticket B you worked on this morning even though its fucking 5 o' clock in the evening. So of course you get confused over wherever you selected the right ticket to begin with. So you have to check that almost everytime.
Alright, rant over.
Let's see if i beed to make another one after their big 'all feature requests on hold, UI redesign, everything will be fixed and much better'-update.5 -

tl;dr: Windows' MAX_PATH is the devil, and it basically does not allow you to copy files with paths that exceed this length. No matter what. Even with official fixes and workarounds.
Long story:
So, I haven't had actual gainful employ in quite awhile. I've been earning just enough to get behind on bills and go without all but basic groceries. Because of this, our electronics have been ... in need of upgrading for quite awhile. In particular, we've needed new drives. (We've been down a server for two years now because its drive died!)
Anyway, I originally bought my external drive just for backup, but due to the above, I eventually began using it for everyday things. including Steam. over USB. Terrible, right? So, I decided to mount it as an internal drive to lower the read/write times. Finding SATA cables was difficult, the motherboard's SATA plugs are in a terrible spot, and my tiny case (and 2yo) made everything soo much worse. It was a miserable experience, but I finally got it installed.
However! It turns out the Seagate external drives use some custom drive header, or custom driver to access the drive, so Windows couldn't read the bare drive. ffs. So, I took it out again (joy) and put it back in the enclosure, and began copying the files off.
The drive I'm copying it to is smaller, so I enabled compression to allow storing a bit more of the data, and excluded a couple of directories so I could copy those elsewhere. I (barely) managed to fit everything with some pretty tight shuffling.
but. that external drive is connected via USB, remember? and for some reason, even over USB3, I was only getting ~20mb/s transfer rate, so the process took 20some hours! In the interim, I worked on some projects, watched netflix, etc., then locked my computer, and went to bed. (I also made sure to turn my monitors and keyboard light off so it wouldn't be enticing to my 2yo.) Cue dramatic music ~
Come morning, I go to check on the progress... and find that the computer is off! What the hell! I turn it on and check the logs... and found that it lost power around 9:16am. aslkjdfhaslkjashdasfjhasd. My 2yo had apparently been playing with the power strip and its enticing glowing red on/off switch. So. It didn't finish copying.
aslkjdfhaslkjashdasfjhasd x2
Anyway, finding the missing files was easy, but what about any that didn't finish? Filesizes don't match, so writing a script to check doesn't work. and using a visual utility like windirstat won't work either because of the excluded folders. Friggin' hell.
Also -- and rather the point of this rant:
It turns out that some of the files (70 in total, as I eventually found out) have paths exceeding Windows' MAX_PATH length (260 chars). So I couldn't copy those.
After some research, I learned that there's a Microsoft hotfix that patches this specific issue! for my specific version! woo! It's like. totally perfect. So, I installed that, restarted as per its wishes... tried again (via both drag and `copy`)... and Lo! It did not work.
After installing the hotfix. to fix this specific issue. on my specific os. the issue remained. gg Microsoft?
Further research.
I then learned (well, learned more about) the unicode path prefix `\\?\`, which bypasses Windows kernel's path parsing, and passes the path directly to ntfslib, thereby indirectly allowing ~32k path lengths. I tried this with the native `copy` command; no luck. I tried this with `robocopy` and cygwin's `cp`; they likewise failed. I tried it with cygwin's `rsync`, but it sees `\\?\` as denoting a remote path, and therefore fails.
However, `dir \\?\C:\` works just fine?
So, apparently, Microsoft's own workaround for long pathnames doesn't work with its own utilities. unless the paths are shorter than MAX_PATH? gg Microsoft.
At this point, I was sorely tempted to write my own copy utility that calls the internal Windows APIs that support unicode paths. but as I lack a C compiler, and haven't coded in C in like 15 years, I figured I'd try a few last desperate ideas first.
For the hell of it, I tried making an archive of the offending files with winRAR. Unsurprisingly, it failed to access the files.
... and for completeness's sake -- mostly to say I tried it -- I did the same with 7zip. I took one of the offending files and made a 7z archive of it in the destination folder -- and, much to my surprise, it worked perfectly! I could even extract the file! Hell, I could even work with paths >340 characters!
So... I'm going through all of the 70 missing files and copying them. with 7zip. because it's the only bloody thing that works. ffs
Third-party utilities work better than Microsoft's official fixes. gg.
...
On a related note, I totally feel like that person from http://xkcd.com/763 right now ;;21 -
The gift that keeps on giving... the Custom CMS Of Doom™
I've finally seen enough evidence why PHP has such a bad reputation to the point where even recruiters recommended me to remove my years of PHP experience from the CV.
The completely custom CMS written by company <redacted>'s CEO and his slaves features the following:
- Open for SQL injection attacks
- Remote shell command execution through URL query params
- Page-specific strings in most core PHP files
- Constructors containing hundreds of lines of code (mostly used to initialize the hundreds of properties
- Class methods containing more than 1000 lines of code
- Completely free of namespaces or package managers (uber elite programmers use only the root namespace)
- Random includes in any place imaginable
- Methods containing 1 line: the include of the file which contains the method body
- SQL queries in literally every source file
- The entrypoint script is in the webroot folder where all the code resides
- Access to sensitive folders is "restricted" by robots.txt 🤣🤣🤣🤣
- The CMS has its own crawler which runs by CRONjob and requests ALL HTML links (yes, full content, including videos!) to fill a database of keywords (I found out because the server traffic was >500 GB/month for this small website)
- Hundreds of config settings are literally defined by "define(...)"
- LESS is transpiled into CSS by PHP on requests
- .......
I could go on, but yes, I've seen it all now.12 -
This story starts over two years ago... I think I'm doomed to repeat myself till the end of time...
Feb 2014
[I'm thrust into the world of Microsoft Exchange and get to learn PowerShell]
Me: I've been looking at email growth and at this rate you're gonna run out of disk space by August 2014. You really must put in quotas and provide some form of single-instance archiving.
Management: When we upgrade to the next version we'll allocate more disk, just balance the databases so that they don't overload in the meantime.
[I write custom scripts to estimate mailbox size patterns and move mailboxes around to avoid uneven growth]
Nov 2014
Me: We really need to start migration to avoid storage issues. Will the new version have Quotas and have we sorted out our retention issues?
Management: We can't implement quotas, it's too political and the vendor we had is on the nose right now so we can't make a decision about archiving. You can start the migration now though, right?
Me: Of course.
May 2015
Me: At this rate, you're going to run out of space again by January 2016.
Management: That's alright, we should be on track to upgrade to the next version by November so that won't be an issue 'cos we'll just give it more disk then.
[As time passes, I improve the custom script I use to keep everything balanced]
Nov 2015
Me: We will run out of space around Christmas if nothing is done.
Management: How much space do you need?
Me: The question is not how much space... it's when do you want the existing storage to last?
Management: October 2016... we'll have the new build by July and start migration soon after.
Me: In that case, you need this many hundreds of TB
Storage: It's a stretch but yes, we can accommodate that.
[I don't trust their estimate so I tell them it will last till November with the added storage but it will actually last till February... I don't want to have this come up during Xmas again. Meanwhile my script is made even more self-sufficient and I'm proud of the balance I can achieve across databases.]
Oct 2016 (last week)
Me: I note there is no build and the migration is unlikely since it is already October. Please be advised that we will run out of space by February 2017.
Management: How much space do you need?
Me: Like last time, how long do you want it to last?
Management: We should have a build by July 2017... so, August 2017!
Me: OK, in that case we need hundreds more TB.
Storage: This is the last time. There's no more storage after August... you already take more than a PB.
Management: It's OK, the build will be here by July 2017 and we should have the political issues sorted.
Sigh... No doubt I'll be having this conversation again in July next year.
On the up-shot, I've decided to rewrite my script to make it even more efficient because I've learnt a lot since the script's inception over two years ago... it is soooo close to being fully automated and one of these days I will see the database growth graphs produce a single perfect line showing a balance in both size and growth. I live for that Nirvana.6 -

And BAM. Wrote a quick'n dirty little php script which works with loads of shell_exec calls to block all ip addresses belonging to an ASN number.
For example: If I get Facebook's ASN number and use it as parameter for this script with a custom name (for the iptables chain), the script creates a chain called the custom name, adds all ip addresses/ranges it got from the whois lookup (on the ASN number) with DROP to iptables and then it adds that chain to the INPUT and OUTPUT chains.
I've done some tests and can indeed genuinely not reach Facebook at all anymore, Microsoft is entirely blocked out as well already 💜16 -
Pro tip: never set custom script stuff related to dns server forcing things in a root firewall app if you don't know what you're doing.
How would I know? There's a slight chance that I just went offline for a few days (mobile only) to figure this shit out 😅
All fixed now, though!21 -

I showed a friend of mine a project I made in two days in Docker and Symfony php. It is a rather simple app, but it did involve my usual setup: Nginx with gzip/cache/security headers/ssl + redis caching db + php-fpm for symfony. I also used php7.4 for the lolz
He complained that he didn't like using Docker and would rather install dependencies with composer install and then run it with a Laravel command. He insisted that he wanted a non-docker installation manual.
I advised him to first install Nginx and generate some self-signed certificates, then copy all the config files and replace any environment-injected values (I use a self-made shell script for this) with the environment values in the docker-compose files.
Then I told him to download php-fpm with php 7.4 alpha, install and configure all the extensions needed, download and set up a local Redis database and at last re-implement a .env file since I removed those to replace them with a container environment.
He sent an angry emoji back (in a funny way)
God bless containerized applications, so easy to spin up entire applications (either custom or vendor like redis/mysql) and throw them away after having played with them. No need to clutter up your own pc with runtime environments.
I wonder if he relents :p9 -
That would probably be implementing multithreading in shell scripts.
https://gitlab.com/netikras/bthread
The idea (though not the project itself) was born back when I still was a sysadmin. Maintaining 30k servers 24/7 was quite something for a team of merely ~14 people. That includes 1st line support as well.
So I built a script to automate most of my BAU chores. You could feed a list of servers - tens or hundreds or more - and execute the same action on each of them (actions could be custom or predefined in the list of templates). Neither Puppet nor Chef or Ansible or anything of sorts was consistently deployed in that zoo, not to mention the corp processes made use of those tools even a slower approach than the manual one, so I needed my own solution.
The problem was the timing. I needed all those commands to execute on all the servers. However, as you might expect, some servers could be frozen, others could be in DMZ, some could be long decommed (and not removed from the listings), etc. And these buggars would cause my solution to freeze for longer than I'd like. Not to mention that running something like `sar -q 1 10` on 200 servers is quite time-consuming itself :)
And how do I get that output neatly and consistently (not something you'd easily get with moving the task to a background with '&'. And even with that you would not know when are all the iterations complete!)?
So many challenges...
I started building the threading solution that would
- execute all the tasks in parallel
- do not write anything to disks
- assign a title to each of the tasks
- wait for all the tasks to complete in either
> the same sequence as started
> as soon as the task finishes
- keep track of each task's
> return code
> output
> command
> sequence ID
> title
- execute post-finish actions (e.g. print to the console) for each of the tasks -- all the tracked properties are to be accessible by the post-finish actions.
The biggest challenges were:
a) how do I collect all that output without trashing my filesystems?
b) how do I synchronize all those tasks
c) how do I make the inception possible (threads creating threads that create their own threads and so on).
Took me some time, but I finally got there and created the libbthread library. It utilizes file descriptors, subshells and some piping magic to concentrate the output while keeping track of all the tasks' properties. I now use it extensively in my new tools - the ones where I can't use already existing tools and can't use higher-level languages.4 -

I also have a custom bash script written that if the message is longer than 50 lines it writes cuts it off with a '...more' and outputs to a file where I can read the full details if needs be.

So I setup a nice csv file for the customer to fill in the shop items for their webshop, you know? with a nice layout like
name - language - description etc.
(just temporary, because the legacy website is going under a ((sadly frontend only)) rework, so it now also has to display different 'kind' of products... and because the new cms isn't done yet they
have to provide the data with other means)
my thoughts were to create a little import script to write the file into the database.... keep in mind of the relations... etc...
guess what? TWO MONTHS later, I get a file with a custom layout, empty cells, sometimes with actual data, sometimes (in red / green text color) notes for me
I mean WHY.... WHY DO YOU MAKE MY LIVE HARDER???
So now I have to put data in 6 columns and 411 rows in the database BY HAND...
oh and did I mention they also have relations? yeah... I also have to do that by hand now...3 -
Dev of 15 years here. All my career historically started and evolved/revolved around Microsoft in one way or the other, so was my exposure to only DOS and the Windows as a child and growing up.
Like already discussed in multiple rants here, I was one of those naturally Windows -favoring ppl through all my life. That is not to say I didn't try Linux here and there, for hosting of personal projects, as one usually does. But it never quite stuck with me as a personal daily driver, mainly because all I ever needed for personal use was a browser, discord, and Steam/GOG/Epic Games store for gaming (work-wise I always had and still have company provided laptops which are OF COURSE Windows powered)
Anyway, maybe you can see where I'm going with this... I recently gave Nobara Linux a go (Glorious Eggroll's Fedora flavor, with some custom kernel patches) and I have to say, not thinking of going back to Windows at all.
Just a few thoughts on comparing two sets of experiences with Win vs Nobara
- Win definitely feels more sluggish
- Nobara's default desktop env was Gnome 42 with some extensions pre-enabled. I dove right into hacking/customizing it to my tastes and it looked glorious. Never would have achieved this customization with Win
- I was using RDP to remote into my work laptop from my personal desktop setup with Windows and I still successfully do so with Remmina now in Linux
- A week ago I dove deeper and installed Awesome window manager as a UI and mh boy does this feel intimidating at first. But then the allure of having nice window managing experience was too strong, and 15 years of coding do help with just seeing a new language and kinda feeling at home instantly (Lua language for AwesomeWM customization/themes). Fast forward a week and now I'm sitting happily with 3 monitor setup, one of them vertical, all properly auto aligned with arandr on startup, variety+wal for wallpaper auto circling and applying a theme out of main wallpaper colors every so often (+wrote a script to put those main colors into my RGB peripherals via OpenRGB)
- Gaming. I still game, Steam Deck from steam gave me all the confidence to set up Linux gaming that I needed. I think I am now properly versed in all things Wine/Proton/Lutris/Bottles/Heroic Games Launcher, you name it. Recently finished Cyberpunk 2077.
ANYWAY, thank you for coming to my Linux appreciation TED talk. It's amazing. -
I’m developing a fairly sophisticated desktop app in Python with PyQt5 as the widget set. Because my partner insists that all the kids these days love Python.
Piss on Python. And that goes double for PyQt5.
I’m on the absolute hardest section of the app. It’s a fairly complex import of data from PDF reports. There are so many different parts that I decided to go with a wizard.
So, I built a QWizard in Qt Designer. It generates a C++ .ui file, but you just truck it over to the command line and run this pyuic5 command, and it converts to a handy dandy Python class. Woo. You can subclass it and consume it from your Python script.
Sounded SO MUCH EASIER than writing the wizard from scratch. But OH NO. I need to do custom validation on my custom text control at every stage to control when the Next and Finish buttons are enabled, which means I gotta overwrite some damn event.
But I can’t. Because I can’t subclass the individual pages. Because they’re part of the same damn file and the wizard offers no access to them.
I’m almost certain that I’m going to have to completely redesign the wizard so that it’s pages are in separate files, which means I have to recode the bitch as well.
The cherry on top is that there’s zero documentation for this specific thing. None. No QWizard documentation exists for PyQt5 (if there is, they’re doing a damn good job of hiding it), so I have to read the documentation for PyQt4. Not the same animal. Close, but different. Even with the differences aside, this documentation is minimal and useless. “We’re going to tell you in very general terms what you should do, but we’ll give you zero idea how to do it. And we know the very common code method you’ll want to try first won’t work.”
And getting at this stuff when you do it in Qt Designer is WAY different. And all that documentation is in C++. Because apparently you HAVE to speak C++ if you want any real info about PyQt. Because that’s perfectly reasonable, right?
So, now I’ve lowered myself and posted a question on Stack. Because, hey, once you get past the power-tripping, mouth-breathing, basement-dwelling, neck-bearded high school punching bags picking apart your question rather than, I dunno..., BEING HELPFUL, sometimes you can get good info there. Sometimes. They seriously saved my ass at least one time.
But yeah. Fuck Python. Fuck everything Qt.17 -
Oh I have quite a few.
#1 a BASH script automating ~70% of all our team's work back in my sysadmin days. It was like a Swiss army knife. You could even do `ScriptName INC_number fix` to fix a handful of types of issues automagically! Or `ScriptName server_name healthcheck` to run HW and SW healthchecks. Or things like `ScriptName server_name hw fix` to run HW diags, discover faulty parts, schedule a maintenance timeframe, raise a change request to the appropriate DC and inform service owners by automatically chasing them for CHNG approvals. Not to mention you could `ScriptName -l "serv1 serv2 serv3 ..." doSomething` and similar shit. I am VERY proud of this util. Employee liked it as well and got me awarded. Bought a nice set of Swarowski earrings for my wife with that award :)
#2 a JAVA sort-of-lib - a ModelMapper - able to map two data structures with a single util method call. Defining datamodels like https://github.com/netikras/... (note the @ModelTransform anno) and mapping them to my DTOs like https://github.com/netikras/... .
#3 a @RestTemplate annptation processor / code generator. Basically this dummy class https://github.com/netikras/... will be a template for a REST endpoint. My anno processor will read that class at compile-time and build: a producer (a Controller with all the mappings, correct data types, etc.) and a consumer (a class with the same methods as the template, except when called these methods will actually make the required data transformations and make a REST call to the producer and return the API response object to the caller) as a .jar library. Sort of a custom swagger, just a lil different :)
I had #2 and #3 opensourced but accidentally pushed my nexus password to gitlab. Ever since my utils are a private repo :/3 -
Previously: http://bu.tl/8t
I wanted to grab a script off another computer, and was getting strange scp errors. Turns out my use of .bashrc to hold all my aliases and custom variables was not "best practice," and scp was flipping out. I renamed my .bashrc files to .bash_profile, and scp worked properly from there. But then, I found that by default xterm doesn't consider an xterm session a "login." So I had to update my .Xresources file with an option for xterm, and re-merge it with xrdb. SO! I was ready to grab my script to set my openbox config the way I like it.
All the while, I noticed that the trackpad tapping didn't work, so that was my next hurdle to take. Next post! -
I dunno about coolest, but I did sort of cement my reputation as the "database guy" in my first job because of this.
My first job was with a group maintaining a series of websites. Because of the nature of the websites, every morning we had to pull the records from one database on one network, sneaker net the data to a database on another network, and import the data via custom data import function.
However, the live site would crash after 100 or so records were imported. The dba at the live site had to script out a custom data partitioning script to do his daily duties, but it definitely messed up his productivity.
Turns out, the custom mass import function had recycled the standard import function, which was only used to import 1 record at a time, and it never closed its database connections, because it never needed to. A one line fix to production code was delivered 6 months later (because that was our release cycle) and I came up with the temporary work around, which was basically removing the connection limit. It would still crash with the work around, but only with multiple days worth of data. So basically only on Monday. Also developed the test set for the import (15k+ records). -
A custom script that makes a Jira ticket, assigns it to me, marks it as in progress, check out a git branch, set the commit title and the Jira title to my command line argument…. Push, open a PR, and fuck it, merge that shit too.
I checked all the corporate boxes and you got the typo fixed. -
Welp, this made my night and sorta ruined my night at the same time.
He decided to work on a new gaming community but has limited programming knowledge, but has enough to patch and repair minor issues. He's waiting for an old friend of his to come back to start helping him again, so this leads to me. He needed a custom backend made for his server, which required pulling data from an SQL/API and syncing with the server, and he was falling behind pace and asked for my help. He's a good friend that I've known for a while, and I knew it wouldn't take to long to create this, so I decided to help him. Which lead to an interesting find, and sorta made my night.
It wasn't really difficult, got it done within an hour, took some time to test and fix any bugs with his SQL database. But this is where it get's interesting, at least for me. He had roughly a few hundred people that did beta testing of the server, anyways, once the new backend was hooked in and working, I realized that the other developer he works with had created a 'custom' script to make sure there are no leaks of the database. Well, that 'custom' script actually begins wiping rows/tables (Depends on the sub-table, some get wiped row by row, some just get completely dropped), I just couldn't comprehend what had happened, as rows/tables just slowly started disappearing. It took me a while of checking, before checking his SQL query logs (At least the custom script did that properly and logged every query), to realize it just basically wiped the database.
Welp, after that, it began to restrict the API I was using, and due to this it identified the server as foreign access (Since it wasn't using the same key as his plugin, even though I had an API key created just so it could only access ranks and such, to prevent abuse) and begin responding not with denied, but with a lovely "Fuck you hacker!" This really made my night, I don't know why, but I was genuinely laughing pretty hard at this response.
God, I love his developer. Luckily, I had created a backup earlier, so I patched it and just worked around the plugin/API to get it working. (Hopefully, it's not a clusterfuck to read, writing this at 2 am with less than an hour of sleep, bedtime! Goodnight everyone.)7 -
My IT-teacher has a website. Aside from it looking like from 1980 (which is ok), he has a "security js Mail decryption":
In his page there is a <script> with a simple yet custom de/encrypt function. Then his E-Mail is an <a href="javascript:mailto:function('rubberish173848'>private email</a>. (Or something like that)
You can just run this link (open email app and read it) or use the same function and same href in the browser console and read it. It sounds so stupid.
(Yet I figured out he probably doesn't want bots to spam his mail, so maybe I am stupid)1 -
Dear client,
I'm trying to import your data into your new system with a one-off custom script. But the fact that you keep screwing around with the data and rules is like jamming a stick in the spokes of the bike you're riding. We're never gonna finish this project if you keep doing that.
Sincerely get a clue,
Me -
Making scripts for custom physics is fun. One moment, the object gets stuck on the ground. The next, it shoots off into the far distance.
Lesson of the day? Don't be an idiot for once, stop, grab a notebook, Google some formulas and think like a human being before messing around with the script again.2 -
OMG... this client is killing me...
So they are writing a Java / SpringBoot app for whatever. For some reason they decided to write it in the overcomplicated way, i.e. using a custom Spring's BeanPostProcessor that changes the eventual type of some beans, causing some weird ass issues, causing the app to fail to boot up if built on some systems and start up just fine if built on others (https://stackoverflow.com/questions...).
I've advised the client (devs) to simplify the architecture and avoid using type-mutating BPPs (bcz.. you know.. noone does that..).
Instead, the client created a task for me to "remove the build logic creating JAR packages" and another "Create a shell script manually assembling the CLASSPATH list and launching the application"
omg... what the hell is going on? Am I on camera? This can't be real... in 202-fucking-4 in a greenfield project!!!
wtf...1 -
Yet another day at my company, Im rewriting some old code for client (rewriting old, php 4 system for vindications managment) and you know the moment when you are focused and someone comes to you to absolutely ruin your focus. Fine, whatever. Oh, for fuck sake. Again dev is doing as support becouse one moron with second can't login into zimbra admin panel and add fucking mailbox. I show them exacly how they login, remind them they are admins too, slowly show them, so you click "manage" than you click that gear icon and than you click "new", fill in email address and password. As simple as 1-2-3. Okay, fuck it, time to go for a cig. I just finish up few lines and stand, grab my vape and start walking towards door. In door I find my buddy with 2 random people. He told me that they are interns and that I should show them some basics and stuff around that. Oh god, fuck my life. If anything, Im definitely very bad teacher, mainly becouse I often have problems with saying what I mean in the way that somebody actually understans and knows what I am trying to say. Whatever. Fuck it all. I grab two of our old laptops that nobody used in like a year or so, and first thing I quickly figure out, is that one day for some what the fuck reason I dont even dont bothered to remember I installed Arch on both while I dont usually use Arch. I just needed it for some specific reason. Whatever. So I guess I will need to upgrade fucking system. Our network isn't really great so that was like... hour or so. In the meantime I figured what they know about coding in general etc, and holly shit. One of them (there was boy and girl), girl, apparently never ever in her life even touched code. Well... fuck. Why am I wasting my time? Becouse there was some programme or some shit like that... Someone could tell me before so I could mentally prepare.. fuck it. whatever. So while laptops are doing their pacman thing, I sit with them and slowly start to explain based on my machine some really basic concepts. Second guy actually had some expirience, he knew how to make some really really basic logic and stuff, so he had another world of problems, becouse it was PHP and, as we all know, everyone hates PHP, and... yeah.. You can probably imagine his approach. Yes, you get user input in super global array. I really wanted to say "Now shut the fuck up and write that fucking $_POST".
hour or so passed, I was close to giving up to not let my anger rise (im not really good teacher... I mentioned it. I suck at teaching others) but luckly machines upgraded. He wanted to use visual studio code, she didnt care too much, so I installed phpstorm in trial mode. whatever. Since that's linux and they were not comfortable with that, I walked them through installing LAMP stack, and when finally it started to look like LAMP stack, I requested them to google how to install xdebug, becouse xdebug is very usefull and googling skill is your best weapon on that field. I go for cig, come back and what I see boiled me a little bit. The girl was stuck looking at github page randomly looking through xdebug source code and idk... hoping for miracle (she admited she thought there will be instructions somewhere) and the guy was in good place, xdebug has a place to paste your phpinfo() for custom instructions. But it didn't work for him, he claims that wizzard told him it cant help him.. hmm intresting, you are sure you pasted in phpinfo? yes, he is sure. Okay, show me.
Again mindblown how someone can have problems with reading.
so his phpinfo() looked like that:
```<?php
phpinfo();```
I highlighted on the page the words "output of phpinfo". He somehow didn't see it or something. He didnt know, he thought that he needs to put in phpinfo so he did. OMG.
Finally, I figured out I can workaround my intern problem, and I just briefly shown them php.net, how documentation looks, said to allways google in english, if he uses tutorial to read whole fucking thing, not just some parts of it, and left them with simple task, that took them whole day and at which they ultimately failed.
To make 3 buttons labeled "1" "2" "3" and if someone presses one of them, remember in session that they pressed it and disallow pressing other ones.
Never fucking again interns. Especially those who randomly without apparent reason almost literally just spawn in front of you and here, its your fucking problem now.
Fuck it, I have some time to get back to my stuff. Time is running so lets not waste it.
After around 15 minutes my one of my superiors comes in and asks me if I can go on meeting with him and other superior. My buddy goes with us, and next 3 hours I was basically explaining that you cannot do some things (ie. know XYZ happened without any source of information) in code, and I can't listen for callbacks from ABC becouse it wont send anyc cuz in their fucking brilliant idea ABC can't even know that this script would even exist, not to mention it wants callbacks.
Sometimes I hate my job.4 -
Sharing a first look at a prototype Web Components library I am working on for "fun"
TL;DR left side is pivot (grouped) table, right side is declarative code for it (Everything except the custom formatting is done declaratively, but has the option to be imperative as well).
====
TL;DR (Too long, did read):
I'm challenging myself to be creative with the cool new things that browsers offer us. Lani so far has a focus on extreme extensibility, abstraction from dependencies, and optional declarative style.
It's also going to be a micro CSS framework, but that's taking the back-seat.
I wanted to highlight my design here with this table, and the code that is written to produce this result.
First, you can see that the <lani-table> element is reading template, data, and layout information from its child elements. Besides the custom highlighting code (Yellow background in the "Tags" column, and green gradient in the "Score" column), everything can be done without opening even a single script tag.
The <lani-data-source> element is rather special. It's an abstraction of any data source, and you, as a developer can add custom data sources and hook up the handlers to your whim (the element itself uses the "type" attribute to choose a handler. In this case, the handler is "download" which simply sends a fetch request to the server once and downloads the result to memory).
Templates are stored in an html file, not string literals (Which I think really fucks the code) and loaded async, then cached into an object (so that the network tab doesn't get crowded, even if we can count on the HTTP cache). This also has the benefit of allowing me to parse the HTML templates once and then caching the parsed result in memory, so templates are never re-parsed from string no matter how many custom elements are created.
Everything is "compiled" into a single, minified .js file that you include on your page.
I know it's nothing extraordinary, but for something that doesn't need to be compiled, transpiled, packaged, shipped, and kissed goodnight, I think it's a really nice design and I hope to continue work on it and improve it over time

I have been spending all day optimizing a wordpess site for pagespeed, looking into how can I optimize the custom scripts which block rendering and I was learning some new things, it was hard but I was making progress. Then comes the senior engineer who installs a plugin and pagespeed went from 60 to 90 on mobile, I was pretty shocked. Then it hit me. IT DELAYS THE LOADING OF EVERY SCRIPT AND IMAGE UNTIL USER INPUT TRICKING THE SCORING SYSTEM. U GET A WHITE SCREEN IF YOU DON'T DO ANYTHING. I told him it's not really faster this way, and he agreed it is not "ethical" but the score is good.
Am I still an idiot naive kid? There is a line between scamming people and quality work, but it keeps getting more blurry.5 -
Fking alfresco and custom script listeners and fuck referencing multiple jars in one single jar and fuck reload time of alfresco server and all :(2

Is there anyone who has ever used frappe/erpnext?
It drives me nuts, as much as I like the framework doing any thing that needs some basic scripting is a pain!
I MEAN, COME ON MAN, WHY ARE DOCS SO HARD TO COME BY? WHY DOES YOUR "CUSTOM SCRIPT" EDITOR LACK BAISIC LINE NUMBERS? WHY ARE YOUR ERROR MESSAGES TELLING ME EVERYTHING BUT THE LINE THE ERROR'S ON, SO I'LL BE HOPEFULL THE ERROR IS IN THE DEV CONSOLE? WHY NOT USE MONACO, SOMETHING, ANYTHING THAT WILL SHOW SYNTAX ERRORS? I'VE WAISTED HOURS ON LITTLE AUTOMATION SCRIPTS!!!! WHY WHY WHY WHY????1 -
My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?2 -
It started when i was about 10 old.
My uncle showed me how to display something in dos-prompt using the echo command in a custom batch-file.
A few commands later, i was able to "program" a flip-book of an ascii ski-driver. Each ascii picture was separated by pressing any key and cls ^^
Aaaaah. Sweet childhood memories!
Later on i used a programming-language for beginners in windows.
This language gave you control of a triangle called "turtle".
My first high-level programming language was Delphi.
Since i had no idea of databases, i created a pseudo database of magic the gathering play-cards. Each card had it's very own windows formular filled up completely with an uncompressed image object displaying the chosen card modally. *sigh*
I scanned each card by using a feed scanner.
Finally, my application consisted of 200 cardimages and forced my PC to swap the required memory from my harddisk.
Boy o boy. I was such a noob! ^^
Over the years i discovered and felt in love with a lot of languages (jsp, java (script), c#, php, ...) and concepts (mvvm, mvc, clean-architecture, tdd, ...)! ;) -
So I'm working on a snippet of JS to generate widgets for a custom data dashboard at the moment, in a project where I've been paired with a junior "developer" (he's more of a junior script monkey though), which is just plain painful...
Recently he wrote up a long message bitching about how my library API keeps changing, making it impossible for him to get any of his work done.. This particular message even made references to "writing his own widget library" and "stabbing me in the eye".
It's currently at version 0.1.0-ALPHA, just by the way. Major version 0 mother fucker.
Anyways, one of my colleagues stepped in the other day to try help him with the front-end stuff, which finally helped me get the feedback I was asking for. At which point we found out he's still currently working off a build I gave him 4 fucking weeks back.
Honestly though, I'd both love and hate to see him try make a library to do this: pull data from a non-standards company data API, parse said data from unnamed number arrays nested up to 4 levels deep, then morph that data into one of four different charts or one of five made up of custom markup.
All he has to do is create a UI to configure and present my widgets, but he can't even figure out how to integrate dependency management into his front-end project.
O.o
OMG. Can I stab him?? Pretty please?1 -
Where do I keep a custom config file?!!!
I have a script in /etc/init.d that runs a program that takes a file as an argument, but I shouldn't keep that file in a user's home directory. Where should it be?6 -
Have to use this custom script language from ABB. I have hever felt this amount of pain in life. Virtually impossible to predict the result, and two compiled versions of the same code might behave different from the other. Please shoot me😖 Sorry, felt I needed to went my frustration. ☺️4

A year ago I built my first todo, not from a tutorial, but using basic libraries and nw.js, and doing basic dom manipulations.
It had drag n drop, icons, and basic saving and loading. And I was satisfied.
Since then I've been working odd jobs.
And today I've decided to stretch out a bit, and build a basic airtable clone, because I think I can.
And also because I hate anything without an offline option.
First thing I realized was I wasn't about to duplicate all the features of a spreadsheet from scratch. I'd need a base to work from.
I spent about an hour looking.
Core features needed would be trivial serialization or saving/loading.
Proper event support for when a cell, row, or column changed, or was selected. Necessary for triggering validation and serialization/saving.
Custom column types.
Embedding html in cells.
Reorderable columns
Optional but nice to have:
Changeable column width and row height.
Drag and drop on rows and columns.
Right click menu support out of the box.
After that hour I had a few I wanted to test.
And started looking at frameworks to support the SPA aspects.
Both mithril and riot have minimal router support. But theres also a ton of other leightweight frameworks and libraries worthy of prototyping in, solid, marko, svelte, etc.
I didn't want to futz with lots of overhead, babeling/gulping/grunting/webpacking or any complex configuration-over-convention.
Didn't care for dom vs shadow dom. Its a prototype not a startup.
And I didn't care to do it the "right way". Learning curve here was antithesis to experimenting. I was trying to get away from plugin, configuration-over-convention, astronaut architecture, monolithic frameworks, the works.
Could I import the library without five dozen dependancies and learning four different tools before getting to hello world?
"But if you know IJK then its quick to get started!", except I don't, so it won't. I didn't want that.
Could I get cheap component-oriented designs?
Was I managing complex state embedded in a monolith that took over the entire layout and conventions of my code, like the world balanced on the back of a turtle?
Did it obscure the dom and state, and the standard way of doing things or *compliment* those?
As for validation, theres a number of vanilla libraries, one of which treats validation similar to unit testing, which seems kinda novel.
For presentation and backend I could do NW.JS, which would remove some of the complications, by putting everything in one script. Or if I wanted to make it a web backend, and avoid writing it in something that ran like a potato strapped to a nuclear rocket (visual studio), I could skip TS and go with python and quart, an async variation of flask.
This has the advantage that using something thats *not* JS, namely python, for interacting with a proper database, and would allow self-hosting or putting it online so people can share data and access in real time with others.
And because I'm horrible, and do things the wrong way for convenience, I could use tailwind.
Because it pisses people off.
How easy (or hard) would it be to recreate a basic functional clone of the core of airtable?
I don't know, but I have feeling I'm going to find out!1 -
....that moment, late at night, when you've just closed that remote terminal to your network media server, tweaking that custom tree listing script, and then you put your phone down and roll over.

so i did this convenient download script that worked like a charm at home only to find out internet is blocked for these kind of things at work. adding a port results in a single connection success that will be blocked on the next attempt. i get it with all the security concerns but am curious which way it-department tells me to download 3k+ files with likely dynamic filenames otherwise...2

I have to build a database migration that generates user handles. The user handles are unique within an organization. The user can change them. The auto generated handles are either the first name + last name, or the business name depending on which user type it is. Unless it would be a duplicate. Duplicates auto increment if the handle is taken. The character limit for a user handle is the same length as first name plus last name so I have to check for possible overflow if I add digits. I also have to see if the generated name is in the DB already because a user could have custom entered the result of the auto generation.
This has to be programmed async. The DB driver is using a transaction but multiple calls have to be made to check if the generated handle exists for that organization. Also I have to check the migration script itself for possible duplicates. 3/4 of the users have a handle and with the scale there will definitely be duplicate names.
My idea is if there is a collision, use a UUID and let the users pick something nicer next time they log in. Business says “Reeeeeee!!!! The users shouldn’t see a UUID!!! You can do this!!!” Absurd uniqueness requirements. Absurd backfill procedure. Absurd business rules.2 -
When people say they wish a language was more strict. I'm a fan of the loose lol.
Tried Python. Script failed due to indent not at right amount. Bye
C#/.NET... Typecasting out the a$$. Goodbye lol
PHP. Anything goes. Hello, this is my kind of world. Never had an issue with types but I write my code to handle values properly.
And I know people will have opposing views. However I will say that you can still achieve the strictness in PHP by putting in your own checks. Create a few custom functions to do your validations and you are good to go :)3 -
Shits ridiculous
So much of my goddamn time wasted
Perfect idea really
Gradually grab all pixel locations that fit space constraints
Remember finishing this script and watching the areas populate

So much goddamn time wasted
Bastards I hate you all !3 -
So, I just (few hours ago)made a new variable that's either brilliant or innately flawed... not sure yet. It's an oddly unique var...
__bs__
So far I only made it in python and windows env (i script like the methodology of css).
I bet you're wondering how I've defined __bs__ and the practicality of it.
__bs__ is derived from a calculated level of bullshit that annoys me to tolerate, maintain, etc. as well as things that tend to throw nonsensical errors, py crap like changing my strings to ints at seemingly random times/events/cosmic alignments/etc or other things that have a history of pulling some bs, for known or unknown reasons.
How/why did this come about now?
Well I was updating some symlinks and scripts(ps1 and bat) cuz my hdd is so close to death I'm wondering if hdd ghosts exist as it's somehow still working (even ostream could tell it should be dead, by the sound alone).
A nonsense bug with powershell allowing itself to start/run custom ps1scripts with the originating command coming from a specific batch script, which worked fine before and nothing directly connected to it has changed.
I got annoyed so took an ironic break from it to work on python crap. Python has an innately high level of bs so i did need to add some extra calculations when defining if a py script or function is actually __bs__ or just py.
The current flavour of py bs was the datetime* module... making all of my scripts using datetime have matching import statements to avoid more bs.
I've kept a log of general bs per project/use case. It's more like a warning list... like when ive spent hours debugging something by it's traceback, meticulous... to eventually find out it had absolutely nothing to do with the exception listed. Also logged aliases i created, things that break or go boom if used in certain ways, packages that ive edited, etc.
The issue with my previous logging is that it's a log... id need to read it before doing anything, no matter how quick/simple it should be, or im bound to get annoyed with... bs.
So far i have it set to alert if __bs__ is above a certain int when i open something to edit. I can also check __bs__ fot what's causing the bs. I plan to turn it into a warning and recording system for how much bs i deal with and have historical data of personal performance vs bs tolerance. There's a few other applications i think ill want to use it for, assume it's not bs itself.
*in case you prefer sanity and haven't dealt with py and datetime enough, here's the jist:
If you were to search any major forum like StackOverflow for datetime use in py, youd find things like datetime.datetime.now() and datetime.now() both used, to get the same returned value. You'll also find tons of posts for help and trying to report 'bugs', way more than average. This is because the datetime package has a name conflict... with itself. It may have been a bug several years ago, but it beeb explicitly defined as intentional since.2 -
Anyone notice how fucking difficult it is to install software from GitHub... well for amateurs mostly. I went through pretty much hell to simply install a spotify playlist downloader script from GitHub. Had I not have had Python installed I would have had to download that too. You Install Python, Google a guide to get the pip command up and running. Download the software. PIP it? Then you find out it uses 3 custom libraries that have to be installed separately. Oh that reminds me, u still need an IDE to open the script and figure that, on your own. Then the script is super buggy, expected though it was still in development. I have no idea where I am going with this. Point is ppl need to get better with hosting code at GitHub. And it wouldn't hurt to include a guide to installation in ReadMe.md OR Installation.md. Ok am done now xd5

Having problems with getting user's IP address with PHP.
So basically I made a custom DDoS protection for my linux server.
It works like this: php website gathers visitor IP address when he does a certain action (in this case registers an account). All visitor ips are stored in ips.txt securely on my website ftp.
Then my linux server has iptables rules setup in a way where it blocks all traffic except my website traffic.
On linux server I have a cron job which pulls whitelisted ips every 5 minutes from my php website FTP and then whitelists all IP's in iptables.
That way only visitor IP's (of those who registered account in my website) are being whitelisted in my linux server.
In case of a DDoS attack, all traffic is dropped except for the whitelisted visitor's IP's gathered from website ips.txt
Now I'm having a problem. My PHP script is not accurate. Some visitors in my website are not being whitelisted because they might have a different ipv4 ip address than what is given from php website. So basically I am looking for some php script/library that would gather ALL ipv4 ips from a visitor, then whitelist them.
Also regarding ipv6, my iptables are all default (which means that all ipv6 visitor traffic is allowed) so problem is not with visitors that have ipv6. Problem is with my script not getting ALL ipv4 ip addresses assigned to the user.
Can you recommend me some php library for that? So far I've used https://github.com/marufhasan1/... but apparently it's not accurate enough.16 -
Unity Controller Support:
Why are controllers awful, it seems like I have to custom each different controller manually to the game. Why can't the the A button on one controller be A on all controllers.
Why can't there be a universal built in controller script that would convert all of the different types controller inputs into a generic controller input that can be translated by just one script instead of writing a script for every common controller... 😠3
