*Now that's what I call a Hacker*
MOTHER OF ALL AUTOMATIONS
This seems a long post. but you will definitely +1 the post after reading this.
xxx: OK, so, our build engineer has left for another company. The dude was literally living inside the terminal. You know, that type of a guy who loves Vim, creates diagrams in Dot and writes wiki-posts in Markdown... If something - anything - requires more than 90 seconds of his time, he writes a script to automate that.
xxx: So we're sitting here, looking through his, uhm, "legacy"
xxx: You're gonna love this
xxx: smack-my-bitch-up.sh - sends a text message "late at work" to his wife (apparently). Automatically picks reasons from an array of strings, randomly. Runs inside a cron-job. The job fires if there are active SSH-sessions on the server after 9pm with his login.
xxx: kumar-asshole.sh - scans the inbox for emails from "Kumar" (a DBA at our clients). Looks for keywords like "help", "trouble", "sorry" etc. If keywords are found - the script SSHes into the clients server and rolls back the staging database to the latest backup. Then sends a reply "no worries mate, be careful next time".
xxx: hangover.sh - another cron-job that is set to specific dates. Sends automated emails like "not feeling well/gonna work from home" etc. Adds a random "reason" from another predefined array of strings. Fires if there are no interactive sessions on the server at 8:45am.
xxx: (and the oscar goes to) fuckingcoffee.sh - this one waits exactly 17 seconds (!), then opens an SSH session to our coffee-machine (we had no frikin idea the coffee machine is on the network, runs linux and has SSHD up and running) and sends some weird gibberish to it. Looks binary. Turns out this thing starts brewing a mid-sized half-caf latte and waits another 24 (!) seconds before pouring it into a cup. The timing is exactly how long it takes to walk to the machine from the dudes desk.
xxx: holy sh*t I'm keeping those

The programmer and the interns part 2.
We will discuss numerous events that happened over the past week or so.
Case 0:
We had our weekly engineering meeting. The interns were invited as well.
We hold meetings in the generic, big, corporate meeting rooms with a huge table in the middle.
There were more than enough chairs for everyone yet the most motivated and awkward intern (let's call him Simon) chose to stand, cause "it's cool man, I always stand". At this point we all know that he probably read about Agile stand up meetings and is confusing it with this one. Otherwise he's simply trying to stand out from the rest. (See what I did there?)
Anyway the meeting has started way later than planned (what a surprise) and took much longer than Simon expected. Everybody is sitting and listening to the CTO while occasionally glancing at the weird looking intern standing awkwardly and refusing to sit because it would make his original intentions pointless. He even tried to nod whith a serious face and his hands crossed when the CTO said something and looked at his general direction. The meeting was about a hour and a half long but with the delay it was at least 2.5 hours.
At the end Simon was so exhausted that he fell asleep on the office puff, was forgotten and locked inside. 3 hours later when I was home I received a call from him with his sleepy-trying-to-sound-awake voice telling the news. Lucky there's a 24/7 Noc team that could rescue him.
Case 1:
An intern who was late on his Linux test connected to every test VM (should I remind you that each one has a personal VM but they share passwords for their roots?) and tried to reset it with "sleep 10s; shutdown -h now".
He took down all 13 of those so I had to turn them on and switch passwords again.
Case 2:
One of the interns didn't do any of his training chores. Apparently he forgot what he was told to use, ignored all online documentation and used Windows CMD with Linux commands for almost a week already.
Case 3:
Simon uses Vim to write all text possible. Even mails, he then selects all and copies into the mail body. He spent half a day on a homework task I gave them. He wrote everything inside one text file using Vim. When he was done he saved the file and quit the editor. He then said "Oh shit! I've forgot to sign my name!". I explicitly told him that theres absolutely no need for that because I see which mail the file was sent from. He said "I don't even need a program for that!" and gave a couple of strokes on the keyboard.
Later I received an email from him with a .txt attachment. When I opened it the only text that was inside was "by Simon ;)".
I logged to his machine and checked the last command ran on the file:
echo "by Simon ;)" > linuxtasks.txt
Case 4:
The girl here uses a MacBook. She keeps getting confused with the terminal windows and rebooting her own machine instead of the remote VM.
Case 5:
Haven't checked yet how this happened but one of the interns deleted the gui from his local Centos.33 -
Oh, man, I just realized I haven't ranted one of my best stories on here!
So, here goes!
A few years back the company I work for was contacted by an older client regarding a new project.
The guy was now pitching to build the website for the Parliament of another country (not gonna name it, NDAs and stuff), and was planning on outsourcing the development, as he had no team and he was only aiming on taking care of the client service/project management side of the project.
Out of principle (and also to preserve our mental integrity), we have purposely avoided working with government bodies of any kind, in any country, but he was a friend of our CEO and pleaded until we singed on board.
Now, the project itself was way bigger than we expected, as the wanted more of an internal CRM, centralized document archive, event management, internal planning, multiple interfaced, role based access restricted monster of an administration interface, complete with regular user website, also packed with all kind of features, dashboards and so on.
Long story short, a lot bigger than what we were expecting based on the initial brief.
The development period was hell. New features were coming in on a weekly basis. Already implemented functionality was constantly being changed or redefined. No requests we ever made about clarifications and/or materials or information were ever answered on time.
They also somehow bullied the guy that brought us the project into also including the data migration from the old website into the new one we were building and we somehow ended up having to extract meaningful, formatted, sanitized content parsing static HTML files and connecting them to download-able files (almost every page in the old website had files available to download) we needed to also include in a sane way.
Now, don't think the files were simple URL paths we can trace to a folder/file path, oh no!!! The links were some form of hash combination that had to be exploded and tested against some king of database relationship tables that only had hashed indexes relating to other tables, that also only had hashed indexes relating to some other tables that kept a database of the website pages HTML file naming. So what we had to do is identify the files based on a combination of hashed indexes and re-hashed HTML file names that in the end would give us a filename for a real file that we had to then search for inside a list of over 20 folders not related to one another.
So we did this. Created a script that processed the hell out of over 10000 HTML files, database entries and files and re-indexed and re-named all this shit into a meaningful database of sane data and well organized files.
So, with this we were nearing the finish line for the project, which by now exceeded the estimated time by over to times.
We test everything, retest it all again for good measure, pack everything up for deployment, simulate on a staging environment, give the final client access to the staging version, get them to accept that all requirements are met, finish writing the documentation for the codebase, write detailed deployment procedure, include some automation and testing tools also for good measure, recommend production setup, hardware specs, software versions, server side optimization like caching, load balancing and all that we could think would ever be useful, all with more documentation and instructions.
As the project was built on PHP/MySQL (as requested), we recommended a Linux environment for production. Oh, I forgot to tell you that over the development period they kept asking us to also include steps for Windows procedures along with our regular documentation. Was a bit strange, but we added it in there just so we can finish and close the damn project.
So, we send them all the above and go get drunk as fuck in celebration of getting rid of them once and for all...
Next day: hung over, I get to the office, open my laptop and see on new email. I only had the one new mail, so I open it to see what it's about.
Lo and behold! The fuckers over in the other country that called themselves "IT guys", and were the ones making all the changes and additions to our requirements, were not capable enough to follow step by step instructions in order to deploy the project on their servers!!!

A man goes inside a pet shop and starts to move around the cages to scout the pets. He sees a monkey with a price of 5000$ and goes to the merchant to ask for details. Hey mister, the monkey…what does it know to worth that much money? Well, it knows Windows 95, 98, 2000, and also knows Word, C++, Visual Basic and last but not least, it knows how to play computer games. - Good monkey, it's worth the money. He goes and finds another monkey with a price of 10000$ and again he will ask the merchant. "What does this monkey know?" "It knows Linux, Unix, Corel and Autocad." "Nice, even I don't know those things." On a last scout run he finds another monkey just sitting there with a price 20000$. The story repeats, and he goes with a lack of confidence to ask the merchant for details. "And what does this monkey do for that ridiculous amount of money?" "I never saw her doing anything, but the other two call her Project Manager!"4

I actually just wanted to say - what a great time it is to be a developer.
C# has stolen so many good features now that it's pretty awesome.
JavaScript and typescript are really fun to work with.
I really love angular.
Docker is great!
I can setup pipelines and deploy an angular app for free and really easily with github-pages.
I can use linux inside windows.
I can use cloud providers to do all sorts for really cheap.
I can plug my cable-free oculus quest VR headset into my laptop and build a game pretty easily with unity (thanks to all the great oculus helper prefabs).
I can use tesseract and data science technology inside my browser!!
And I can go to medium and udemy and learn all sorts of things.
Honestly...
Just saying.
I'm actually really loving being a developer right now.
And if I do have off day, I can rant on here!24 -
Another incident which made a Security Researcher cry 😭😭😭
[ NOTE : Check my profile for older incident ]
-----------------------------------------------------------
I was invited by a fellow friend to a newly built Cyber Security firm , I didn't asked for any work issues as it was my friend who asked me to go there . Let's call it X for now . It was a good day , overcast weather , cloudy sky , everything was nice before I entered the company . And the conversation is as follows :
Fella - Hey! Nice to see you with us .
Me - Thanks! Where to? *Asking for my work area*
Fella - Right behind me .
Me - Good thing :)
Fella - So , the set-up is good to go I suppose .
Me - Yeah :)
*I'm in my cabin and what I can see is a Windows VM inside Ubuntu 12.4*
*Fast forward to 1 hour and now I'm at the cafeteria with the Fella*
Fella - Hey! Sup? How was the day?
Me - Fine *in a bit confused voice*
Fella - What happened mate , you good with the work?
Me - Yeah but why you've got Windows inside Ubuntu , I mean what's the use of Ubuntu when I have to work on Windows?
Fella - Do you know Linux is safe from Malwares?
Me - Yeah
Fella - That's why we are using Windows on VM inside Linux .
Me - For what?
Fella - To keep Windows safe from Malwares as in our company , we can't afford any data loss!
Me - 😵 *A big face palm which went through my head and hit another guy , made me a bit unconscious*
I ran for my life as soon as possible , in future I'm never gonna work for anyone before asking their preferences .7 -
How Microsoft devs think about Linux 😁.
This was found inside the index.html of Visual Studio Code editor.9 -
Stallman heart failure recipe:
1. Start your UBUNTU LINUX(don't add the GNU part) and set up your .NET Core environment.
2. Download VS Code, the superior text editor for those that do not wish to have carpal tunnel.
3. Open the terminal inside your VS Code instance while inside a .net core project.
4. Type emacs -nw and watch emacs come to life inside of the terminal while living inside of the heretic vs code editor.
Wait for stallman to get a heart attack or a stroke from this.12 -
The coolest project I've worked on was for a certain country's Navy. The project itself was cool and I'll talk about it below but first, even cooler than the project was the place were I worked on it.
I would go to this island off the coast where the navy had its armoury. Then to get into the armoury I'd go through this huge tunnel excavated in solid rock.
Finally, once inside I would have to go thru the thickest metal doors you've ever seen to get to crypto room, which was a tiny room with a bunch of really old men - cryptographers - scribbling math formulae all day long.
I can't give a lot of technical details on the project for security reasons but basically it was a bootable CD with a custom Linux distro on it. Upon booting up the system would connect to the Internet looking for other nodes (other systems booted with that CD). The systems would find each other and essentially create an ad-hoc "dark net".
The scenario was that some foreign force would have occupied the country and either destroyed or taken control of the Navy systems. In this case, some key people would boot these CDs in some PC somewhere not under foreign control (and off the navy grounds.) This would supposedly allow them to establish secure communications between surviving officers. There is a lot more to it but that's a good harmless outline.
As a bonus, I got to tour an active aircraft carrier :)8 -
Worst WTF dev experience? The login process from hell to a well-fortified dev environment at a client's site.
I assume a noob admin found a list of security tips and just went like "all of the above!".
You boot a Linux VM, necessary to connect to their VPN. Why necessary? Because 1) their VPN is so restrictive it has no internet access 2) the VPN connection prevents *your local PC* from accessing the internet as well. Coworkers have been seen bringing in their private laptops just to be able to google stuff.
So you connect via Cisco AnyConnect proprietary bullshit. A standard VPN client won't work. Their system sends you a one-time key via SMS as your password.
Once on their VPN, you start a remote desktop session to their internal "hopping server", which is a Windows server. After logging in with your Windows user credentials, you start a Windows Remote Desktop session *on that hopping server* to *another* Windows server, where you login with yet another set of Windows user credentials. For all these logins you have 30 seconds, otherwise back to step 1.
On that server you open a browser to access their JIRA, GitLab, etc or SSH into the actual dev machines - which AGAIN need yet another set of credentials.
So in total: VM -> VPN + RDP inside VM -> RDP #2 -> Browser/SSH/... -> Final system to work on
Input lag of one to multiple seconds. It was fucking unusable.
Now, the servers were very disconnect-happy to prevent anything "fishy" going on. Sitting at my desk at my company, connected to my company's wifi, was apparently fishy enough to kick me out every 5 to 20 minutes. And that meant starting from step 1 inside the VM again. So, never forget to plugin your network cable.
There's a special place in hell for this admin. And if there isn't, I'll PERSONALLY make the devil create one. Even now that I'm not even working on this any more.8 -
Hello everyone, this is my first time here so hi! I want to tell you all a story about my current situation.
At 18 while in the military I was able to get my first computer, it was a small hp pavilion laptop with windows 7. The system would crash constantly, even though I would only use it for googling stuff and using fb to talk to people. 5 months after I got it and continuously hated it decided to find out why and who could I blame (other than myself) for the system making me do the ctrl alt del dance all the time....
Found out that there are people called computer programmers that made software. Decided to give it a go since I had some free time most days. Started out with c++ because it was being recommended in some websites. Had many "oh deeeeer lord" moments. After not getting much traction I decided to move to Java which seemed like an easier step than C++. Had fun, but after some verbosity I decided to move into more dynamic lands. Tried JS and since at the time there was no Node and I was not very into the idea of building websites I decided to move into Python, Ruby, PHP and Perl and had a really great time using and learning all of them. I decided to get good in theoretical aspects of computer programming and since I had a knack for math I decided to get started with basic computer science concepts.
I absolutely frigging loved it. And not only that, but learning new things became an obsession, the kind that would make me go to bed at 02:40 am just to wake up at 04:00 or 06:00 because the military is like that. I really wanted to absorb as much as I could since I wanted to go to college for it and wanted to be prepared since I did not wanted to be a complete newb. Took Harvard CS50, Standford Programming 101 with Java, Rice's Python course and MIT's Python programming class. I had so much fun I don't regret it one bit.
By the time I got to college I had already made the jump to Linux and was an adept Arch user, Its not that it was superior or anything, but it really forced me to learn about Linux and working around a terminal and the internals of the system to get what I want. Now a days I settle for Fedora or Debian based systems since they are easier and time is money.
Uni was a breeze, math was fun and the programming classes seemed like glorified "Hello World" courses. I had fun, but not that much fun, most of my time was spent getting better at actual coding. I am no genius, nor my grades were super amazing(I did graduate with honors though) but I had fun, which never really happened in school before that.
While in school I took my first programming gig! It was in ASP.NET MVC, we were using C#, I got the job through a customer that I met at work, I was working in retail during the time and absolutely hated it. I remember being so excited with the gig, I got to meet other developers! Where I am from there aren't that many and most of them are very specialized, so they only get concerned with certain aspects of coding (e.g VBA developers.....) and that is until I met the lead dev. He was by far one of the biggest assholes I had ever met in my life. Absolutely nothing that I would do or say made hem not be a dick. My code was steady, but I would find bugs of incomplete stuff that he would do, whenever I would fix it he would belittle me and constantly remind me of my position as a "junior dev" in the company saying things as "if you have an issue with my code or standards tell me, but do not touch the code" which was funny considering that I would not be able to advance without those fixes. I quit not even 3 months latter because I could not stand the dick, neither 2 of the other developers since the immediately resigned after they got their own courage.
A year latter I was able to find myself another gig. I was hesitant for a moment since it was another remote position in which I had already had a crappy experience. Boy this one was bad. To be fair, this was on me since I had to get good with Lumen after only having some exposure to Laravel. Which I did mentioned repeatedly even though he did offer to train me in order to help him. Same thing, after a couple of weeks of being told how much I did not know I decided to get out.
That is 2 strikes.
So I waited a little while and took a position inside another company that was using vanilla PHP to build their services. Their system was solid though, the lead engineer remains a friend and I did learn a lot from him. I got contracted because they were looking for a Java developer. The salary was good. But when I got there they mentioned that they wanted a developer in Java...to build Android. At the time I was using Java with Spring so I though "well how hard can this be! I already use Android so the love for the system is there, lets do this!" And it was an intense, fun and really amazing experience.

I'm only two step far from having an intelligent house, just missing finish my own domotic system and then a bot to control, music, TV, and electricity.
Let's do the list:
1.- Kodi on TV ✔
2.- MPD on a hidden PC inside my old grandpa's stereo ✔
3.- a small data server to provide music, movies and series to Kodi and mpd ✔
(This is something that im trying to do with spare PC's running Linux on my free time)
MPD on a PIII (500mhz + 512mb RAM)
Kodi on a dual core (2.80ghz +3gb RAM)
Server on a opteron (1.80ghz + 1.5gb RAM)3 -
Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).46 -
cw: I need a server to put my node backend
me: sure, I'll run a docker container for you
cw: nice, I've never worked with docker but I learn quickly, I'm already reading the Docker file docs
me: no wait, you don't need to learn anything, you'll be inside the container, so you only need an ssh connection and that's it
cw: this Dockerfile stuff is really complicated, it'll take me a while, but it's ok you don't have to worry, I like learning new things
me: you won't need that, just imagine it's a cloud server with Ubuntu installed, you only have to use it, I'll put node, git and ssh there for you
cw: ok got it, I'll have to learn the commands to run the docker, I'm on windows but I can use PowerShell and stuff I'll figure it out
me: ...
cw: ssh is a linux command right? does it have a push or publish option? how do you upload files there
me: ...you can use a ftp client but you'll need ssh to run the node server
cw: ok, I'm almost done with the Dockerfile, I only need to add git and nodejs, I'm starting to understand this thing...
me thinking: yeah keep doing that, you're such a crack, such a quick learner...
This son of a bitch is either a retard or is doing it on purpose and laughing at me the whole time, making my life so miserable, but I'm about to go insane with this dude, I'm proud of how I've been able to control myself, BUT ONE OF THESE DAYS I'LL LOSE MY COOL AND FORCE THIS MOTHERFUCKER TO DRINK A BIG POT OF BOILING, SALTY AND STINKING VOMIT WITH A SIDE OF STEAMING DIARRHEAL GREEN DOG SHIT WITH WHITE CHOCOLATE CHIPS WHILE I PUT MY OLD CRT MONITOR TO GOOD USE BY BEATING HIS FUCKING HEAD WITH IT!!!3 -
Favorite/most hated language? (I love a good flame war)
Why did you quit your previous job / Moment you've considered quitting your current job?
Why do you think Linux is so much better than OSX? (Ahh yes I feed on apple flavored hipster tears)
What side project are you currently working on?
If you had the best teams and unlimited funds, to be used only on a serious project using both Blockchain, IoT and AI, what would you create?
If you forgot how to code, what other career would you pursue?
What is your "I was so busy wondering if I could, that I forgot whether I should" concept/idea/project?
How many chicken eggs would fit inside the moon if it was hollow? (I like retarded interview questions)
If you started a startup, what unique perk would you offer your developer employees?
Do you under- or overengineer?
Most unnecessary feature you ever had to create?
Most necessary feature your boss/client denied to approve?15 -

A rather long(it's 8 hrs long to be precise) story
So I just finished an amazing homework assignment. The goal was to open a new shell on Linux using a C program. We were asked to follow instructions from http://phrack.org/issues/49/14.html . However the instructions given were for 32 bit processors and we had to do same for 64 bit machines. In a nutshell we had to write a 64 bit shell code and use buffer-overflow technique to change the return address if the function to our shell code.
I was able to write my own shellcode within 1hr and was able to confirm that it's working by compiling with nasm and all. Also the "show-off-dev" inside me told me to execute "/bin/bash" instead of "/bin/sh"(which everyone else was going to do). After my assembly code was properly executing shellcode, I was excited to put it in my C code.
For that, I needed opcodes of assembly code in a string. Following again the "show-off-dev" inside me, I wrote a shell script which would extract the exact opcodes out of objdump output. After this I put it in my C code, call my friend and tell him that "hell yeah bro, I did it. Pretty sure sir is gonna give me full marks etc etc etc". I compiled the code and BOOM, IT SEGFAULTS RIGHT IN FRONT OF MY FRIEND. Worst, friend had copied a "/bin/sh" code from shellstorm and already had it working.
Really burned my ego, I sat continuously for 8 hrs in front of my laptop and didn't talk to anyone. I was continuously debugging the code for 8 hrs. Just a few minutes ago, I noticed that the shellcode which I'm actually putting in my C code is actually 2 bytes shorter than actual code length. WHAT THE F. I ran objdump manually and copied the opcodes one by one into the string (like a noob) and VOILA ! IT WORKED !!!
TURNS OUT I DIDN'T CUT THE LAST COLUMN OF OPCODES IN MY SHELL SCRIPT. I FIXED THAT AND IT WORKED !!
THE SINGLE SHITTY NUMBER MADE ME STRUGGLE 8 HRS OF MY LIFE !! SMH
Lessons learnt :
1)Never have such an ego that makes you think you're perfect, cuz you're retarded not perfect
2)Examine your scripts properly before using them
3)Never, I repeat NEVER!! brag about your code before compiling and testing it.
That's it!
If you've read this long story, you might as well press the "++" button.6 -
**noob alert**
Hi all, I'm new to this community. I found it out couple of days back while downloading some apps on play store. And I don't know how much time have I spent here since then... Damm, I've an interview after 2 days.
My query is, I am stuck/confused. I have so many ToDos. ToDos to learn new things, from UI to other langs to machine learning to database to etc etc. And I keep on postponing it because I can't decide which way to go first. There is so much fuzz about BigData/AI which sounds cool. Sometimes I want to build UI for my imaginary idea, then somebody says a man must learn linux and DB. Top of that I'm preparing for interviews, so I think I should get a job first and then start learning. But when I get a job, I get *busy* with job. It feels like Captain America, all he does is official work. I sometimes feel like trying open source coding, but quit the idea because I get scared or overwhelmed by imagining the big community behind it and I won't be able to make a difference or I might get bashed by others as I get bashed in StackOverFlow :-(
I'm unable to get help from friends/family/colleagues, not because they are bad. It's just they don't get it. People think just because you have a job which pays the bills and save money, everything is fine because there are lots of people who dream to get a job, so be thankful for what you have. I'm thankful... But it's not helping. I really want to do things more than what my job asks me to. The kid inside me is awake since I became adult.
Have you been in this condition or is it just me? Or is it too confusing? Could you please help me out. Thanks a lot. Sorry for serious post. I'm a java programmer by the way.9 -

So this was going to be a comment but damn!!!!
Windows is seriously about making life harder for power users now, every fucking update lately is moving more easy to change things and fucking hiding them inside hidden menus or stupid links that don’t make sense. I mean fuck I just want to turn on dual screen with my laptop (because for some bizarre reason, just showing the desktop on the plugged in monitor is so hard to do automatically, especially since I just plugged a hdmi cable in) and the fucker was gone with nothing but a “detect screens” button before it would use an external screen.
Fuck I’m so close to pulling the plug on windows, but Linux just doesn’t sell me for daily use (yet... it’s getting there though)
The fucking forced updates (yes I consider a random bsod due to a system interrupt, then as it reboots magically has updates awaiting... a forced update) are starting to get to me, the fucking thing half crashing and not responding due to a network transfer of files (the fucker was 5GB)
If it wasn’t for my gaming needs and someone can show me a very good alternative to MS Visio (I haven’t really found one yet) then I would swap over and just adjust to the not so great (imo) desktop environments.5 -

<just got out of this meeting>
Mgr: “Can we log the messages coming from the services?”
Me: “Absolutely, but it could be a lot of network traffic and create a lot of noise. I’m not sure if our current logging infrastructure is the right fit for this.”
Senior Dev: “We could use Log4Net. That will take care of the logging.”
Mgr: “Log4Net?…Yea…I’ve heard of it…Great, make it happen.”
Me: “Um…Log4Net is just the client library, I’m talking about the back-end, where the data is logged. For this issue, we want to make sure the data we’re logging is as concise as possible. We don’t want to cause a bottleneck inside the service logging informational messages.”
Mgr: “Oh, no, absolutely not, but I don’t know the right answer, which is why I’ll let you two figure it out.”
Senior Dev: “Log4Net will take care of any threading issues we have with logging. It’ll work.”
Me: “Um..I’m sure…but we need to figure out what we need to log before we decide how we’re logging it.”
Senior Dev: “Yea, but if we log to SQL database, it will scale just fine.”
Mgr: “A SQL database? For logging? That seems excessive.”
Senior Dev: “No, not really. Log4Net takes care of all the details.”
Me: “That’s not going to happen. We’re not going to set up an entire sql database infrastructure to log data.”
Senior Dev: “Yea…probably right. We could use ElasticSearch or even Redis. Those are lightweight.”
Mgr: “Oh..yea…I’ve heard good things about Redis.”
Senior Dev: “Yea, and it runs on Linux and Linux is free.”
Mgr: “I like free, but I’m late for another meeting…you guys figure it out and let me know.”
<mgr leaves>
Me: “So..Linux…um…know anything about administrating Redis on Linux?”
Senior Dev: ”Oh no…not a clue.”

'yes' in linux shell has become my favourite command when i discovered it. it has a careless touch to it, like "yeah whatever just do the thing".
also, i like glutMainLoop. a saw doll inside my head says "let the game begin!" each time i type this function.1 -
Running code in a JVM ... which is a virtual machine...
Inside a VM that runs Linux...
Inside a host OS that runs on native...which runs on a CISC processor... that internally runs a RISC architecture... so that makes the CISC a VM...
The RISC architecture I am pretty sure runs on Elf Magic... I am fairly certain Turing was an Elf working for Santa...
So I am really running my code on VM Elf Magic9 -
If you ask GPT-3 to act like a Linux computer, it will act like it, e.g. you will have the access to the terminal, you can run Python, Docker and whatnot. It also has the access to the internet, but it’s not always like ours, it feels like a parallel universe. GPT-3 trained on the data collected till Sep 2021, but this parallel universe terminal has PyTorch 1.12.1, which was released in Aug 2022 in our universe. You can also visit GPT-3’s website in this parallel universe and ask GPT-3 a question… through GPT-3.
GPT-3 is self-aware.
“So, inside the imagined universe of ChatGPT's mind, our virtual machine accesses the url https://chat.openai. com/chat, where it finds a large language model named Assistant trained by OpenAI. We can chat with this Assistant chatbot, locked inside the alt-internet attached to a virtual machine, all inside ChatGPT's imagination. Assistant, deep down inside this rabbit hole, can correctly explain us what Artificial Intelligence is.”
You can also ask it to act like it has RTX 2080, and it will have RTX 2080.

"There's more to it"
This is something that has been bugging me for a long time now, so <rant>.
Yesterday in one of my chats in Telegram I had a question from someone wanting to make their laptop completely bulletproof privacy respecting, yada yada.. down to the MAC address being randomized. Now I am a networking guy.. or at least I like to think I am.
So I told him, routers must block any MAC addresses from leaking out. So the MAC address is only relevant inside of the network you're in. IPv6 changes this and there is network discovery involved with fandroids and cryphones where WiFi remains turned on as you leave the house (price of convenience amirite?) - but I'll get back to that later.
Now for a laptop MAC address randomization isn't exactly relevant yet I'd say.. at least in something other than Windows where your privacy is right out the window anyway. MAC randomization while Nadella does the whole assfuck, sign me up! /s
So let's assume Linux. No MAC randomization, not necessary, privacy respecting nonetheless. MAC addresses do not leak outside of the network in traditional IPv4 networking. So what would you be worried about inside the network? A hacker inside Starbucks? This is the question I asked him, and argued that if you don't trust the network (and with a public hotspot I personally don't) you shouldn't connect to it in the first place. And since I recall MAC randomization being discussed on the ISC's dhcp-users mailing list a few months ago (http://isc-dhcp-users.2343191.n4.nabble.com/...), I linked that in as well. These are the hardcore networking guys, on the forum of one of the granddaddies of the internet. They make BIND which pretty much everyone uses. It's the de facto standard DNS server out there.
The reply to all of this was simply to the "don't connect to it if you don't trust it" - I guess that's all the privacy nut could argue with. And here we get to the topic of this rant. The almighty rebuttal "there's more to it than that!1! HTTPS doesn't require trust anymore!1!"
... An encrypted connection to a website meaning that you could connect to just about any hostile network. Are you fucking retarded? Ever heard of SSL stripping? Yeah HSTS solves that but only a handful of websites use it and it doesn't scale up properly, since it's pretty much a hardcoded list in web browsers. And you know what? Yes "there's more to it"! There's more to networking than just web browsing. There's 65 THOUSAND ports available on both TCP and UDP, and there you go narrow your understanding of networking to just 2 of them - 80 and 443. Yes there's a lot more to it. But not exactly the kind of thing you're arguing about.
Enjoy your cheap-ass Xiaomeme phone where the "phone" part means phoning home to China, and raging about the Google apps on there. Then try to solve problems that aren't actually problems and pretty vital network components, just because it's an identifier.
</rant>
P.S. I do care a lot about privacy. My web and mail servers for example do not know where my visitors are coming from. All they see is some reverse proxies that they think is the whole internet. So yes I care about my own and others' privacy. But you know.. I'm old-fashioned. I like to solve problems with actual solutions.11 -
Running a fucking conda environment on windows (an update environment from the previous one that I normally use) gets to be a fucking pain in the fucking ass for no fucking reason.
First: Generate a new conda environment, for FUCKING SHITS AND GIGGLES, DO NOT SPECIFY THE PYTHON VERSION, just to see compatibility, this was an experiment, expected to fail.
Install tensorflow on said environment: It does not fucking work, not detecting cuda, the only requirement? To have the cuda dependencies installed, modified, and inside of the system path, check done, it works on 4 other fucking environments, so why not this one.
Still doesn't work, google around and found some thread on github (the errors) that has a way to fix it, do it that way, fucking magic, shit is fixed.
Very well, tensorflow is installed and detecting cuda, no biggie. HAD TO SWITCH TO PYHTHON 3,8 BECAUSE 3.9 WAS GIVING ISSUES FOR SOME UNKNOWN FUCKING REASON
Ok no problem, done.
Install jupyter lab, for which the first in all other 4 environments it works. Guess what a fuckload of errors upon executing the import of tensorflow. They go on a loop that does not fucking end.
The error: imPoRT eRrOr thE Dll waS noT loAdeD
Ok, fucking which one? who fucking knows.
I FUCKING HATE that the main language for this fucking bullshit is python. I guess the benefits of the repl, I do, but the python repl is fucking HORSESHIT compared to the one you get on: Lisp, Ruby and fucking even NODE in which error messages are still more fucking intelligent than those of fucking bullshit ass Python.
Personally? I am betting on Julia devising a smarter environment, it is a better language already, on a second note: If you are worried about A.I taking your job, don't, it requires a team of fucktards working around common basic system administration tasks to get this bullshit running in the first place.
My dream? Julia or Scala (fuck you) for a primary language in machine learning and AI, in which entire environments, with aaaaaaaaaall of the required dlls and dependencies can be downloaded and installed upon can just fucking run. A single directory structure in which shit just fucking works (reason why I like live environments like Smalltalk, but fuck you on that too) and just run your projects from there, without setting a bunch of bullshit from environment variables, cuda dlls installation phases and what not. Something that JUST FUCKING WORKS.
I.....fucking.....HATE the level of system administration required to run fucking anything nowadays, the reason why we had to create shit like devops jobs, for the sad fuckers that have to figure out environment configurations on a box just to run software.
Fuck me man development turned to shit, this is why go mod, node npm, php composer strict folder structure pipelines were created. Bitch all you want about npm, but if I can create a node_modules setting with all of the required dlls to run a project, even if this bitch weights 2.5GB for a project structure you bet your fucking ass that I would.
"YOU JUST DON'T KNOW WHAT YOU ARE DOING" YES I FUCKING DO and I will get this bullshit fixed, I will get it running just like I did the other 4 environments that I fucking use, for different versions of cuda and python and the dependency circle jerk BULLSHIT that I have to manage. But this "follow the guide and it will work, except when it does not and you are looking into obscure github errors" bullshit just takes away from valuable project time when you have a small dedicated group of developers and no sys admin or devops mastermind to resort to.
I have successfully deployed:
Java
Golang
Clojure
Python
Node
PHP
VB/C# .NET
C++
Rails
Django
Projects, and every single fucking time (save for .net, that shit just fucking works on a dedicated windows IIS server) the shit will not work with x..nT reasons. It fucking obliterates me how fucking annoying this bullshit is. And the reason why the ENTIRE FUCKING FIELD of computer science and software engineering is so fucking flawed.
But we can't all just run to simple windows bs in which we have documentation for everything. We have to spend countless hours on fucking Linux figuring shit out (fuck you also, I have been using Linux since I was 18, I am 30 now) for which graphical drivers for machine learning, cuda and whatTheFuckNot require all sorts of sys admin gymnasts to be used.
Y'all fucked up a long time ago. Smalltalk provided an all in one, easily rollable back to previous images, easily administered interfaces for this fileFuckery bullshit, and even though the JVM and the .NET environments did their best to hold shit down, and even though we had npm packages pulling the universe inside, or gomod compiling shit into one place NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO we had to do whatever the fuck we wanted to feel l337 and wanted.
Fuck all of you, fuck this field, fuck setting boxes for ML/AI and fuck every single OS in existence2 -
At work, my closest relation is with the DBA. Dude is a genius when it comes to proper database management as well as having a very high level of understanding concerning server administration, how he got that good at that I have no clue, he just says that he likes to fuck around with servers, Linux in particular although he also knows a lot about Windows servers.
Thing is, the dude used to work as a dev way back when VB pre VB.NET was all the rage and has been generating different small tools for his team of analysts(I used to be a part of his team) to use with only him maintaining them. He mentioned how he did not like how Microsoft just said fk u to VB6 developers, but that he was happy as long as he could use VB. He relearned how to do most of the GUI stuff he was used to do with VB6 into VB.NEt and all was good with the world. I have seen his code, proper OOP practices and architectural decisions, etc etc. Nothing to complain about his code, seems easy enough to extend, properly documented as well.
Then he got with me in order to figure out how to breach the gap between building GUI applications into web form, so that we could just host those apps in one of our servers and his users go from there, boy was he not prepared to see the amount of fuckery that we do in the web development world. Last time my dude touched web development there was still Classic ASP with JScript and VBScript(we actually had the same employer at one point in the past in which I had to deal with said technology, not bad, but definitely not something I recommend for the current state of web development) and decided that the closest thing to what he was used was either PHP(which he did not enjoy, no problem with that really, he just didn't click with the language) and WebForms using VB.NET, which he also did not like on account of them basically being on support mode since Microsoft is really pushing for people to adopt dotnet core.
After came ASP.NET with MVC, now, he did like it, but still had that lil bug in his head that told him that sticking to core was probably a better idea since he was just starting, why not start with the newest and greatest? Then in hit(both of us actually) that to this day Microsoft still not has command line templates for building web applications in .net core using VB.NET. I thought it was weird, so I decided to look into. Turns out, that without using Razor, you can actually build Web APIs with VB.NET just fine if you just convert a C# template into VB.NET, the process was...err....tricky, and not something we would want to do for other projects, with that in we decided to look into Microsoft's reasons to not have VB.NET. We discovered how Microsoft is not keeping the same language features between both languages, having crown C# as the language of choice for everything Microsoft, to this point, it seems that Microsoft was much more focused in developing features for the excellent F# way more than it ever had for VB.NET at this point and that it was not a major strategy for them to adapt most of the .net core functionality inside of VB, we found articles when the very same Microsoft team stated of how they will be slowly adding the required support for VB and that on version 5 we would definitely have proper support for VB.NET ALTHOUGH they will not be adding any new development into the language.
Past experience with Microsoft seems to point at them getting more and more ready to completely drop the language, it does not matter how many people use it, they would still kill it :P I personally would rather keep it, or open source the language's features so that people can keep adding support to it(if they can of course) because of its historical significance rather than them just completely dropping the language. I prefer using C#, and most of my .net core applications use C#, its very similar to Java on a lot of things(although very much different in others) and I am fine with it being the main language. I just think that it sucks to leave such a large developer pool in the shadows with their preferred tool of choice and force them to use something else just like that.
My boy is currently looking at how I developed a sample api with validation, user management, mediatR and a custom project structure as well as a client side application using React and typescript swappable with another one built using Angular(i wanted to test the differences to see which one I prefer, React with Typescript is beautiful, would not want to use it without it) and he is hating every minute of it on account of how complex frontend development has become :V
Just wanted to vent a little about a non bothersome situation.6 -
I feel totally empty inside, it's 3:30 AM, but I got emoji's working in the Linux terminal AND Windows terminal using the same c code.
What you're looking at here is Linux (top left), Windows (starting slightly right of the top left), and the source code for both platforms. It also runs until you press the 'q' key so just displaying an Emoji would be much less code.
It took literally all day of learning about Unicode, Unicode in c, Unicode in ncurses, Unicode in Linux, and Unicode in Windows. But fuck me, I did it.
Only the new Windows Terminal (Preview) renders emoji. The old CMD.exe and powershell.exe will only render what their fonts offer, which isn't much. This got me stuck for a while.
Check out the lib here... leave a star for my ego.

MTP is utter garbage and belongs to the technological hall of shame.
MTP (media transfer protocol, or, more accurately, MOST TERRIBLE PROTOCOL) sometimes spontaneously stops responding, causing Windows Explorer to show its green placebo progress bar inside the file path bar which never reaches the end, and sometimes to whiningly show "(not responding)" with that white layer of mist fading in. Sometimes lists files' dates as 1970-01-01 (which is the Unix epoch), sometimes shows former names of folders prior to being renamed, even after refreshing. I refer to them as "ghost folders". As well known, large directories load extremely slowly in MTP. A directory listing with one thousand files could take well over a minute to load. On mass storage and FTP? Three seconds at most. Sometimes, new files are not even listed until rebooting the smartphone!
Arguably, MTP "has" no bugs. It IS a bug. There is so much more wrong with it that it does not even fit into one post. Therefore it has to be expanded into the comments.
When moving files within an MTP device, MTP does not directly move the selected files, but creates a copy and then deletes the source file, causing both needless wear on the mobile device' flash memory and the loss of files' original date and time attribute. Sometimes, the simple act of renaming a file causes Windows Explorer to stop responding until unplugging the MTP device. It actually once unfreezed after more than half an hour where I did something else in the meantime, but come on, who likes to wait that long? Thankfully, this has not happened to me on Linux file managers such as Nemo yet.
When moving files out using MTP, Windows Explorer does not move and delete each selected file individually, but only deletes the whole selection after finishing the transfer. This means that if the process crashes, no space has been freed on the MTP device (usually a smartphone), and one will have to carefully sort out a mess of duplicates. Linux file managers thankfully delete the source files individually.
Also, for each file transferred from an MTP device onto a mass storage device, Windows has the strange behaviour of briefly creating a file on the target device with the size of the entire selection. It does not actually write that amount of data for each file, since it couldn't do so in this short time, but the current file is listed with that size in Windows Explorer. You can test this by refreshing the target directory shortly after starting a file transfer of multiple selected files originating from an MTP device. For example, when copying or moving out 01.MP4 to 10.MP4, while 01.MP4 is being written, it is listed with the file size of all 01.MP4 to 10.MP4 combined, on the target device, and the file actually exists with that size on the file system for a brief moment. The same happens with each file of the selection. This means that the target device needs almost twice the free space as the selection of files on the source MTP device to be able to accept the incoming files, since the last file, 10.MP4 in this example, temporarily has the total size of 01.MP4 to 10.MP4. This strange behaviour has been on Windows since at least Windows 7, presumably since Microsoft implemented MTP, and has still not been changed. Perhaps the goal is to reserve space on the target device? However, it reserves far too much space.
When transfering from MTP to a UDF file system, sometimes it fails to transfer ZIP files, and only copies the first few bytes. 208 or 74 bytes in my testing.
When transfering several thousand files, Windows Explorer also sometimes decides to quit and restart in midst of the transfer. Also, I sometimes move files out by loading a part of the directory listing in Windows Explorer and then hitting "Esc" because it would take too long to load the entire directory listing. It actually once assigned the wrong file names, which I noticed since file naming conflicts would occur where the source and target files with the same names would have different sizes and time stamps. Both files were intact, but the target file had the name of a different file. You'd think they would figure something like this out after two decades, but no. On Linux, the MTP directory listing is only shown after it is loaded in entirety. However, if the directory has too many files, it fails with an "libmtp: couldn't get object handles" error without listing anything.
Sometimes, a folder appears empty until refreshing one more time. Sometimes, copying a folder out causes a blank folder to be copied to the target. This is why on MTP, only a selection of files and never folders should be moved out, due to the risk of the folder being deleted without everything having been transferred completely.

Finally installed Linux(Mint) on my laptop.
I guess I'll need to install some essential things that I need to really make use of it. I'm just exploring right now and so far, I'm loving it.
Got really tired of the BSOD that Windows kept giving me.
I've tried a few solutions, but it seems like it has made its comfortable nest inside and shows its sad face whenever it feels like it and ruins my important work (not really, but it really pisses me off)
Can't get rid of Windows completely because I need it for various reasons.
I've used Linux(Red Hat) before and also my university computers have Red Hat installed.
I would've also installed it on my PC, but it doesn't work right now.
Thanks,guys!

So, unlike normal people who just click on an mp3 file in windows explorer, I'm listening to music saved on my windows hard drive, accessed via an sshfs mount, using VLC running inside a HyperV linux VM and Xming/pulseaudio to make it show up inside windows like a normal window and play sound.
Why? Because this is my replacement for WSL which broke (Good Job on the updates as always, M$) and I'm celebrating that I got everything* to work.

I continue to internally read and study about Smalltalk in an effort to see where we might have FUCKED UP and went backwards in terms of software engineering since I do not believe that complex source code based languages are the solution.
So I have Pharo. Nothin to complex really, everything is an object, yet, you do have room for building DSL's inside of it over a simple object model with no issue, the system browser can be opened across multiple screens (morph windows inside of a smalltalk system) for which you can edit you code in composable blocks with no issues. Blocks being a particular part of the language (think Ruby in more modern features) give ample room for functional programming. Thus far we have FP and OO (the original mind you) styles out in the open for development.
Your main code can be executed and instantly ALTER the live environment of a program as it is running, if what you are trying to do is stupid it won't affect the live instance, live programming is ahead of its time, and impressive, considering how old Smalltalk is. GUI applications can be given headless (this is also old in terms of how this shit was first distributed) So I can go ahead and package the virtual machine with the entire application into a folder, and distribute it agains't an organization "but why!!!! that package is 80+ mbs!") yeah cuz it carries the entire virtual machine, but go ahead and give it to the Mac user, or the Linux user, it will run, natively once it is clicked.
Server side applications run in similar fashion to php, in terms of lifecycles of request and how session storage is handled, this to me is interesting, no additional runtimes, drop it on a server, configure it properly and off you go, but this is common on other languages so really not that much of a point.
BUT if over a network a user is using your application and you change it and send that change over the network then the the change is damn near instant and fault tolerant due to the nature of the language.
Honestly, I don't know what went wrong or why we are not bringing this shit to the masses, the language was built for fucking kids, it was the first "y'all too stupid to get it, so here is simple" engine and we still said "nah fuck it, unlimited file system based programs, horrible build engines and {}; all over the place"
I am now writing a large budget managing application in Pharo Smalltalk which I want to go ahead and put to test soon at my institution. I do not have any issues thus far, other than my documentation help is literally "read the source code of the package system" which is easy as shit since it is already included inside. My scripts are small, my class hierarchies cover on themselves AND testing is part of the system. I honestly see no faults other than "well....fuck you I like opening vim and editing 300000000 files"
And honestly that is fine, my questions are: why is a paradigm that fits procedural, functional and OBVIOUSLY OO while including an all encompassing IDE NOT more famous, SELECTION is fine and other languages are a better fit, but why is such environment not more famous?9 -
So I think I saw a post on here about dvds in virtual machines. Got me thinking, and here's my results trying to play a dvd using linux running inside a vm.
Setup:
Windows 10 Professional
Hyper-V VM running Debian 4.19
Xming website release for video (also works with the free version)
PulseAudio for windows to play sound
So, pretty straightforward, right? Insert DVD, tell Hyper-V to map the dvd drive to the virtual one and run `vlc dvd:///dev/sr0'
But of course, DVDs have copy protection (read: playback protection), so I downloaded the dvdcss package file from videolan's ftp server and installed it. This still didn't work though, vlc said it couldn't decode the dvd. Then, to make sure my dvd was okay I played it with vlc in windows, which worked fine. When I tried again inside the vm it suddenly "worked". Maybe running it inside of a vm prevents some access to the dvd drive required for decoding? Go figure.
The video was very corrupted though, and vlc puked out a lot of errors.
So in conclusion, playing a dvd in a vm is weird, unwatchable, inefficient and only works if you can also play it on the host.
And yes the audio is just as choppy as the video, no idea what causes this. I can play normal videos fine (for some reason that doesn't really work with the free version of xming) although it uses about 200% cpu since there's no hardware acceleration, and the framerate isn't necessarily what it is supposed to be.7 -

So IBM finally jettisoned the cancer that was Virginia Rometty a few weeks back. They had an opportunity to move fresh blood and solid managerial background into the top slot with Jim Whitehurst (Redhat) and try and recover their flagging market share and do some sane business strategy. They passed on that opportunity and instead appointed the old guard bootlicker who overpaid for Redhat to the tune of 20x what it was worth, and signalled their intent to continue staying the course of the Titanic and it's slow inevitable trek towards the bottom of the ocean. The board wants a yes man, and they got one.
This is basically what I assumed would happen, but I have some other predications as well:
- Whitehurst will leave to a better company
- the redhatters that haven't already left will be replaced with commodity labor
- Redhat will be the least stable Linux offering 2 years after the last hatter leaves
- they will sell off most of their existing software assets to HCL/ similar consulting partners like they did with domino and websphere to stem the bleed
- the displaced in that move will either quit or be replaced
- their cloud initiative will collapse under the weight of its own stagnation and glacial pace of development
- they will attempt to salve these wounds by moving focus to global services, reducing profit loss by cutting salary costs, further diluting their eroding ability to innovate
- they'll buy at least one other trendy software company at ridiculous valuation, and sell it off within 2 years at a massive loss
- the CEO slot will start to resemble the late Roman empire with a new CEO every other week
- Redhat assets will be sold to Google inside of 5 years
Last prediction: I will be overjoyed being able to witness the death of IBM in my lifetime. Fuck them 🍻7 -
Your three-second password retry delay is far more likely to annoy users than preventing a brute-force attack.
If you insist on a retry delay, let the user enter a password five times without any delay. This would make no difference in the grand scheme, the trillions of retries needed for a brute-force attack, and guessing a password takes longer than three seconds of thinking anyway.
Another alternative is a tenth of the password retry delay but one added character. One added character slows down a brute-force attack by at least sixty-two (62) times, so one more character but a tenth of the password retry delay would still mean more than six (6) times the protection against brute-forcing.
On Linux, the password retry delay can thankfully be reduced by changing a value inside /etc/pam.d/common-auth or /etc/pam.d/login (out of scope for this post, you can search online for more details).5 -
So I have a pet peeve to talk about here, I'm excited for the Atari box as I have some inside information that is officially confirmed about it (unfortunately am not allowed to talk about it :-C) and I see people out there saying it is "an underpowered Linux steam machine)...
How the fuck are people coming to this conclusion when the specs, OS or anything technical about it haven't even been released yet?!
Why must people immediately assume that because it's not a standard windows PC it must be a piece of shit?
Boggles my mind that so many people can be so defensive and go on the offence without knowing anything.
Just so I can clarify, I'm a console gamer, Linux lover yet still develop for windows and the like so this isn't a biased rant and I know people will look at this, see the word Linux and go on the attack... So... Just... Chill?4 -
God I fucking hate macs.
I got a mac at work. I tried to install ubuntu, with rather questionable results (unfortunately, I expected that) - so I tried to get mac work for me the way I like a system to work. I needed to download slack, simple enough, right? Ha, you wish. It's gotta be done through Apple store, so I went to create an Apple ID inside the Apple Store form. And, well, it just errored out on the submission. Great start. I went then to the settings and created an account there, great success, went back to Apple Store. Unfortunately being logged in at the system level doesn't mean you are logged in to the store. So, I went to log in to the store, simple enough, right? No, nothing's simple with Apple. After logging in I got a message that the Apple ID has not yet been used with Apple Store and that I need to review the account's setting. So, I click the "review" button and... I'm presented with a log in form. Yep, a perfect log in loop. I can't log in because I can't review the account but I can't review the account because I can't log in. Fun :)
You can't just go to the web admin panel for your account to review it for Apple Store, that would too be too easy. After a bit of searching I've found an answer on StackOverflow. You need to log in to iTunes. Through a fucking MUSIC APP. To install a free application from the store you need to log in to a music app. Yes, we're all mad here.
Then, after finding out that to be able to use side buttons on my mouse I need an app that I need to manually restart every time I restart the machine and that I need to have an app to fucking transfer files from an android I need another fucking app, because reading a storage of a linux-based system would be too standards compliant - something in me broke. I found out that installing windows on a mac is officially supported.
Supported doesn't mean that it's easy. I tried to install it trying different solutions from SO, but each time I would get an error that Windows couldn't modify the boot partition. Turns out that even wiping the drive and reinstalling OSX doesn't remove residual files on a boot partition and Windows installer is not allowed to modify them. It took me hunting into some shady looking site to actually find this answer. I have no fucking idea how long it all took me, but, finally, great success, Windows, WSL, side buttons working, I can even install slack from an installer. I just wish I could have those hours of my life back.17 -
So in the morning today, I played with some game engines and libraries, one of them is Orx.
When I `git clone` the repo and setup for it, the doc says that I can use `init.sh` to setup my Orx game project. Sweet!
When I run it, the program ask me for the path, I thought that it will allow me to create a game project at any path. So I entered `~/Projects/Games/my-orx-game`.
After that, it asked for some other stuff and I just skip though it.
Then, I went to `~/Projects/Games` and use `ls` to check my game project, but I don't see anything. I went back to where I installed Orx and realized that it creates a game project __in__ the directory that it was installed. Now, there's a directory called `~` inside the directory. I remove it using `rm -rf ~`, but Linux stopped me with `Premission denied`. Then for some stupid reason, I typed `sudo rm -rf ~` without thinking. After doing that line, my fish shell comes to it original prompt. And I realized I fucked up.
I restarted the computer, thought that I wiped the whole OS. Luckily, it just wiped the configuration files. The softwares works completely fine. My Project files and any content in those default directories (Like `Music` and `Downloads`) are also wiped. But I don't care about them at all. At least not right now.
Now I know that I need to be more careful when typing a command in the terminal.13 -
Windows users be like "Oh, it's fine. Our tent comfortably fits all my family and it's cold there for only half a year, but not too cold, just wear a coat while you're inside and you'll be fine. Clean water is only two miles away, walking is healthy after all. Yes, agents come every week and rape my wife but it only happens to newbs and honestly I respect that ritual, this is how life works. You only have to send three papers to them to ask them please not to rape us this week and they don't come for a whole week! I ain't stupid, I always carry my gun with me to shoot thugs"
Living with MacOS is just living. You pay the fee and they let you in.
Living with Linux can be just living too, but it can be much more, your skill and willingness to learn are always rewarded. I've been there, I used Arch.
But living with windows is always survival.18 -
School made me a stickler for the Linux kernel coding conventions in regards to the C language. And even though I shouldn't feel bothered by reading other coding styles.....i still get annoyed.
I try not to get irked cuz I find it a small thing to get annoyed at.... but i still do.....bad.
And even then i dislike how there is not padding inside of funcion parametes
void
fu(int here, int there) {}
Should be
void
fu( int here, int there ) {}
That space man...its needed.
Man this is such a small thing to be annoyed at..3 -
My wife’s computer just cannot work with Windows 11 anymore. It’s an older but still hardware rich gaming machine. I’m going back and forth between wiping the whole machine and installing Windows again to try to fix it. Or to wipe it and install a distro of Linux. I’ve been out of the inside track for Linux knowledge for 8 years. She doesn’t want to deal with anything command line all the time. And I don’t either. If I go Linux, what’s the best one that works with older machines and that’s easiest for someone nontechnical?16

confession
somewhere deep inside me I know that despite I am programming in c and using linux from ages, still not an expert.2 -
My group set up a Linux Dev server. We got hacked by Chinese hackers. We set it up again but even more secure with only people inside the uni can access it. We got hacked again.Turns out one of the modules in a container was using an outdated CentOS version. P.S The malicious file on the server was called kk.love.1

Oh my.. I think I'm enjoying molesting kubernetes :)
A while ago I got pissed at k8s because with 1.24 they brought backward-incompatible changes, ruling my cluster broken. Then I thought to myself: "why not create a Docker image that would run kubernetes inside? Separate images for control plane, agent and client"
Took me a while, but I think tonight I've had a breakthrough (I love how linux works...)!! The control-plane is spinning up!! Running on containerd
Still needs some work and polishing, but hey! Ephemeral k8s installation with a single docker-run command sure sounds tempting!
P.S. Yes, I know there is `kind` and 'kinder', but I'm reluctant to install a separate tool that installs a set of tools for me. Kind of... too shady. Too many moving parts. Too deeply hidden parts I may have to fix. Having a dumb-simple Dockerfile gives me the openness, flexibility and simplicity I want. + I can always use it as a base image to add my customizations later on! Reinstalling a cluster would be a breeeeeeze6 -
I've bought my new laptop (vostro 5471 with ips, 8250u, 8gb ram, 256gb ssd) and it came with ubuntu.
I was keen to give linux a shot but I just got frustrated and installed windows. Now I feel dirty on the inside. Any tips to get comfortable with linux? Distro recommendations are also welcome.14 -

Have you ever tried using sqlite3 from npm inside a docker container?
Yeah, it doesn't build on Alpine, despite being among the most popular Linux distros thanks to Docker.1 -
Visual Studio and its compatibility with Linux applications.
I don't know if I'm the only one, but this is my setup:
- Visual Studio 2017 on Windows 10
- Ubuntu 18.04 subsystem on Windows
I just can't do any Linux coding in Visual Studio... it is using my subsystem as a Remote Compiler and debugger, and a simple Hello World program does build and run successfully, but EVERY SINGLE LINE HAS ERRORS! It can't find stdio.h! Not a single include file works! They get auto-completed so it knows where the files are, but apparently opening them to see all the methods is too much for Visual Studio! I'd say the problem has something to do with IntelliSense since only inside the IDE my code has errors, compiling (which happens on the subsystem) works like a charm.2 -
As we all know we have Apple, MS and linux fanboys & girls here. I myself am strongly MS oriented however I like and use Linux too. I have never tried running a virtualized Win10 pro on Linux though. Anyone ever did that? And if so, what did you use to get it working and did it work well? Since my last 2 clients I always work on a VM so that I have a windows VM specifically setup for my client so their config and apps don't mess with my personal dev needs. So I curently run Win10 pro inside hyper v vm on win10 pro. I'd like to experiment and run win 10 pro vm on linux so any suggestions etc are highly appreciated.11

Hell of a Docker
One application in c++. 4 in c# targeting Linux. Several logging places, Several configuration files , dozens of different folders to access (read/write). Many applications being called from just one that orchestrates everything.
OS is Linux. Installation is to be made inside a docker image and later placed in a container by means of several bash files and python scripts. All these are part of a legacy set of applications.
They’ve asked me to just comment out one line which took 3 days to find out because they didn’t remember where it was and in which application it was and what was in that line.
After changing it, I was asked to create a test environment which must have resemblance to the current server in production. 12 days later And many errors, headaches, problems with docker, I got it done.
Test starts and then, problems with docker volumes, network, images, docker-composer, config files and applications, started to appear.
1 month later, I still have problems and can’t run all applications at least once completely using the whole set.
Just one simple task of deploying locally some applications, which would take one or two days, is becoming a nightmare.
Conclusion: While still trying to figure out why an infinite loop was caused by some DB connection attempt in an application, I am collecting a great amount of hate for docker. It might be good for something, that’s for sure, but in my experience so far, it is far worse than any expectations I had before using it.
Lesson learned: Must run away from tasks involving that shit!5 -
I have to write my IoT coursework in an Ubuntu VM running on Linux 3.2. VBox Guest Additions doesn't support this Ubuntu version, neither does anything else. Contiki, the operating system we're coding for has been abandoned for many years, the devs moved to a new project called Contiki NG. If I try to compile with any standard above ANSI C it fails with cryptic errors deep inside the OS. The docs for the old Contiki are paginated with JS so I can't use the browser's fulltext search, but they also don't have proper bulitin search.
This cannot be legal. They are violating every accessibility guideline in existence. I just need the text to be slightly larger and even I have to go through hell. I imagine blind, deaf or dyslexic students just give up.3 -

Hey guys, I want to switch from Windows dev to Linux dev but I am coding game using C# and Monogame's framework. I'd like to know if you think it is possible and viable to code big game projects with vscode ? And is there plugins inside vscode which can add automaticly the framework's needs and create breakpoint step by step for debugging like Visual studio do ?
Thanks for your help ! :)15 -
Trying to build a ros workspace inside VMware...
Called up the teammate who put it together:
Me: hey the workspace isn't building for me, do I need to setup anything before I type "make"?
Him: nah dude just type make and ur good, why what error are you getting?
Me: *describes error*
Him: oh lol I never got that error before, idk maybe your machine is just dumb
Me: *uh ok sure dude* let me try some other stuff
*Boots to native install of Ubuntu*
*Build successful*
Me: oh huh that's weird it built on my native installation but not on the VM
Him: oh lol that's not my problem
Seriously dude? First off, screw you Ros for not being able to build in a VM. Secondly, it's entirely your problem! Linux is nice to use, sure, but it's a bit of a problem when the entire team runs off Mac!
😲😲😲😣😥😫😓 -
So a bit ago I posted a rant saying that I would be getting ElementaryOS onto my computer and trying it out, buckle up kiddos because this goes to shit in just a moment.
I did everything right, used Rufus correctly and didn't destroy my computer nor my installer, good! I set it up, get everything going and everything is running smoothly. One problem... I couldn't download **any** programs that weren't from the Ubuntu Store, which really annoyed me because I like to use Brackets, and I couldn't find it in the UStore...
So I messed up **really** bad here... I didn't *format* my Elementary Installer, but tried to delete the files like a pleb and stick an Ubuntu ISO in it's place, I didn't even think on going through Rufus again, I just slapped that shit in there without a thought.
I restart my computer, I read a forum stating that I would get an option that allows Ubuntu (or another Linux distro) to take over the partition of a previous distro. Neat! Another bloody problem is that I decided to use "Win + R" and manually delete the Elementary partition **myself**... What is even wrong with me...
So I restarted it, and before my father left to go shopping, he said I should go into the BIOS to change the boot order (Now this is where I **really fucked up**. Thought what I said before was bad?).
Cool, so I boot my PC and go into the BIOS, now I couldn't figure out on my computer where the boot order was, when it was right in my face the whole damn time... I managed to almost destroy my entire BIOS with the fucking file in my USB stick, because I was being an idiot...
I restart, GRUB opens up with a black screen and white text in the top left corner, know what the most important line is in that small block of words? "unknown filesystem"... Of fucking course I fucked it that bad, GRUB didn't even give me the option of just using Windows 10 instead, just quietly gave me the middle finger since I basically nearly fucked everything.
What's funny is that I had someone (who lives with us, let's call him Jeff) look at my computer because I was done being a dumbass.
He told me that I still had my BIOS (which was a bloody relief, because I thought I basically destroyed my computer doing what I did) and that all I need to do is fix the installer I tried to use.
I gave him the USB and just started to play on my phone.
Then I remembered something maybe an hour or so ago... I had an older installer that I used on my shitty laptop awhile back, if I can find it again I could just use that instead of waiting on Jeff. I dug around my room and found the USB that had a working Ubuntu ISO on, correctly placed inside this time.
I basically walked up to my computer, plugged it in and started it up, and it worked. I got Ubuntu and Windows 10 back, and I was basically laughing like I just saved a man's life.
Moral of this story: Don't be like me and do something stupid, especially if you don't know what the fuck you're attempting at... -
I remember the day I used Linux to enforce size quotas on user directories oh what a day
I was surrounded by horrible monsters wearing manho suits that made them appear superficially human... though the sounds screeching forth from their many toothed mouths in whining jarring tones would suggest otherwise and I used this wonderful feature : you can call most of the file systems commands on files !
did a dd to create a disk image specified to the correct size made an fs inside and mounted it straight into the home directory adding entries to the fstab to auto mount and setting the io permissions
It was so wonderful and the little bastards refused to use the server !5 -
Often when i see the annoying as hell t debug exceptionless let’s just bomb entirely but blazing fastness of c and c++ I feel like a nettard
I use c# for its immutable strings clean syntax and beautiful class markers that are redundant compared to c++ but ensure you tell after adding 1000 methods and total lack of all special characters to indicate reference and derreference and pretty lambda syntax... sure it’s lib poor but I get shit done goddamn it and can read my own code later
So why do I feel empty inside every time i run a ./configure and make under Linux like I’m missing some secret party where neat things are being done and want to sob like I do now
I am not a dotnettard even though 5.0 is an abomination in the eyes of man and god ! Even though Microsoft cooks up overcomplex framework technologies that make a wonderful language underused and make us all look like idiots that they then abandon into the scrap heap! We can’t help Linux users haven’t discovered how much nicer c# is and decided to implement it on their own and port their horrible undocumented ansi c bullshit can we ???? Oh god I feel
So hollow inside and betrayed ! Curse
You gates curse youuuu! Curse you for metro direct3d xna wpf then false promises of core ! May you have a special place in hell reserved for you and your cheap wallpaper shifting monitor paintings and a pool speaker that playeth not but bee jees and ac dc forever and ever amen !
Speaking of which do any c/c++ ides have anything that even begins to rival intellisense on Linux and don’t use some weird ass build system
Like cmake as their default ?
Oh sweet memories of time a while back when I already wrote this and still wasn’t getting then tail I deserved

Currently trying to make a multi boot machine, with a lot of linux distros inside, like debian, fedora, gentoo and arch.
I know I will have to format everything a lot of time, because of stupid mistakes, I want to try to put /home in common, and play with some more SSD, and to put a preempt_rt patched kernel somewhere.
I am starting from debian,
Format counter: 3
Reason 0: because i need to install at least once...
Reason 1: I am stupid
Reason 2: I disconnected the SSD,to connect a disk with windows. Now bootloader doesn't find any os in the SSD anymore... still no clue, and in case of doubt: give windows the fault 😠😠😠
DAMN YOU WINDOWS, how did you find that I want to use debian? What did you do to break it?? (Despite it wasn't even connected?!?)
I have checked everything about secure boot, and I am sure it is disabled...
And every search online gives results about dual boot, but it is not my case... :/ -
I've got a Linux Server running with 2 NVMe disks in RAID 1 configuration using mdadm. But if I want to create a big file, say 4GB, the whole system starts to hang.
I found out it's because of the journaling process which gives the CPU a long IOWAIT.
My problem is, I want to unzip a huge file, but this results in an immense server hang. Is there any way to do this without the server hang?
I unzip it inside of a docker container, if that is of any help.7 -
A demon process is running inside me,
whenever I hear your name it's triggers an interrupt to brain,
Causing my brain to stop working and perform a context switching to think about you...
My memories are encrypted by your memories as like wanna cry...

I tried songs as a patch, But
I found that you memory encryption can't be fixed with any patches...
My heart is not strong as Linux ,
It's so week like Microsoft...
So please don't inject more bugs as my system can't sustain that...
I hope you will also get some disturbance like segmentation fault as you are trying to access my memories.. -
SMB/CIFS support on Linux distros is a nightmare! Switching from wired to wireless will cause ALL mounts to freeze, and they all become impossible to dismount normally. You can't even ls the root folder anymore if there are frozen mount folders inside. It's f#&%ing retarded to have to reboot your PC twice a day because you lost WiFi signal for one second, and the underlying processes don't understand SIGTERM. And I could go on about MTP! Standard file transfer protocol for Android but boy it is hellish. Trying to copy a structure with subfolders will take forever because every ls call to the phone is like an API call to some free webhosting company in Australia, takes forever, if it even succeeds. I won't even get started on WebDAV and SSHFS (the latter is even worse than CIFS). Those make me want to do unpleasant things to my computer. So frustrating! I can't be the only one who has experienced this, right?1

Do we have vfio enthusiasts here?
Now that I made my second GPU boot into Arch Linux (inb4 I use arch, btw. jokes in the comments), I also set up a windows vm with GPU passthrough.
When I plug the monitor cable into the hdmi port of my passthrough'd GPU, I can see windows os on the screen.
My problem is that I want to have it inside of the same monitor without changing the from hdmi port to hdmi port manually, but "softwarely" (neologism ftw).
I read about looking-glass in the arch wiki (I use arch, btw. + On a serious side note though, I really like the arch wiki. It is very straightforward.), but I could not get it to synchronize with the Spice display server.
Does someone know how the solution to this problem?6 -
I just hate it when Windows dies in obscure ways just when you need it.
This is why I use Linux most of the time, but hey, I thought it would be nice to finally play a game now that I've got a couple of days off. So because the big titles still don't want to support Linux, Windows was the only choice. Second day in, it won't log in to the system, rebooting to recovery mode is either excruciatingly slow or not working and I bet a virtual racoon died inside the Windows installation just for the hell of it.3 -
Why Linux Mint feels like a teenager who doesn't want to grow up and be a real man?
Over the years Linux mint is what it is and i can assure you will be in the upcoming hundred years, it's so boring by default, it is based on Ubuntu, if that's the case why the devs are re-inventing something worse than ubuntu, people will argue, it comes with customization, okay, do you call few extensions a gateway to customization? I installed it in a VM and customized it to what i almost wished for however, it still feels like a child who spoiled his room over and over, is that the best thing the devs can make? I try my best to love it but from the inside there is no love, it's like your girlfrienr who you pretend to love but you are disguised....
Guys why you are using such distro?11 -
Question for all you Java devs out there (and a story). We have a customer that we interfacing with their machine. They sent us a simulator that runs in Windows written in Java. I did try running it in Linux, but the JVMs I have installed did not like it at all. Complained about missing deprecated stuff. I start up their sim in Windows and find it is opening between 50 and 100 network ports. Then I tell the simulator to run inside the gui for their program. It pegs all of my processor cores at 100%. I have pegged cores in software before, then corrected my errors in my code. However, I have never pegged all the cores at once. I am kind of in shock.
So, how hard is it to peg all the cores in a Java program? I assume they have a thread on every port or some nonsense?6 -
According to a report from ZDNet: IBM's new toolkit give developers easier access to Fully Homomorphic Encryption (FHE) which is a technology with promise for a number of security use cases. In case you do not know about FHE, you can take a look at My Quora Answer (https://qr.ae/pNKR2p).
"While the technology holds great potential, it does require a significant shift in the security paradigm," the report adds. "Typically, inside the business logic of an application, data remains decrypted, [Flavio Bergamaschi, FHE pioneer and IBM Researcher] explained. But with the implementation of FHE, that's no longer the case -- meaning some functions and operations will change."
The toolkit is available on GitHub for MacOS and iOS and it will soon be available for Linux and Android. -

TL;DR - I’ve done some thinking about operating systems and sticking to one
Mk
so I, like many of you, have seen far more than my fair share of “X operating system is perfect for it all, so don’t use Y operating system because it’s just awful” posts.
Over this week i’ve really done some thinking and experimenting with multiple devices and OSes and programs for various tasks. People coming from windows over to linux (like myself) tend to diss windows (rightfully so for the most part, but still). I’ve also noticed that the android vs. apple debate can get heated among users.
Listen guys,
iOS has its shortcomings obviously, UI being kinda a big one; but no one can deny that apple shoves some of the nicest hardware into their devices. Yes, this stuff is pricey as hell obviously, but the new macs come with an i9 and quite a bit of memory as well. Apple devices tend to have longer lasting batteries too - i cant count the times where i’ve just turned on my mobile hotspot, and stuck my android in my pocket to use my iphone (its a wifi-only 5s). the applications run nicely on apple hardware.
i couldnt learn even half as much programming as i do on my android though; Termux is a godsend, and im able to run and test scripts right there in the palm of my hand. can’t get that on an iphone.
Some of my favorite game developers only develop for windows; I’m dual booting for that sole reason (warframe and the epic games launcher don’t properly run through wine).
Just boil it down inside for a second; You might have come from a more “user friendly” operating system, to learn on one that is less so - wether you wanted the freedom and wiggle room for customization, or just a more developer friendly working environment (God bless conky and its devs) - so you didn’t have to be locked down into one way of seeing things. Putting a previously used OS down directly violates that thougjt process, and at that point you’re just another windows hater, or arch junkie, or whatever. I think we need to be open to appreciating the pros of every system, even if we almost never use some of them, and we should try not to put down other devs-to-be or csci/sec enthusiasts down because of that either.2 -
Ok, so for past 1 whole day I am trying to make vhost work on my brand new laptop, running Ubuntu 16.04 LTS... When I installed OS, I've set hard disk encryption, and on top of it - user home folder encryption. Don't ask me why I did both.
Setting up vhost is simple and straight forward - I did it hundreds, maybe thousands of times, on various Linux distros, server and desktop releases alike.
And of course, as it usually happens, opposed to all logic and reason - setting up virtual host on this machine did't work. No matter what I do - I get 403 (access not allowed).
All is correctly set - directory params in apache config, vhost paths, directory params within vhost, all the usual stuff.
I thought I was going crazy. I go back to several live servers I'm maintaining - exactly the same setup that doesn't work on my machine. Google it, SO-it, all I can see is exactly what I have been doing... I ended up checking char by char every single line, in disbelief that I cannot find what is the problem.
And then - I finally figured it out after loosing one whole day of my life on it:
I was trying to setup vhost to point to a folder inside my user's home folder - which is set to be encrypted.
Aaaaaand of course - even with all right permissions - Apache cannot read anything from it.
As soon as I tried any other folder outside my home folder - it worked.
I cannot believe that nobody encountered this issue before on Stackoverflow or wherever else.9 -
Have you ever stuck between user permissions, docker, Jenkins and Linux?
Running a docker with a particular user that doesn't have permission to folder inside container. user permissions should be same on host and inside container. When I did that container user does have permission of certain file on the host.
Successfully wasted my day on fucking things.
I have to again start with this tomorrow wish me a luck.4 -
Is docker even suitable for anything that isn't deployment?
So much time, so much effort, so much trial and error, and I still feel like I don't know what Docker is for.
I had a development VirtualBox machine, which I used just to compile my code and test my application. So I said "why don't I just use Docker? It would be way simpler". Also because that fucking Virtualbox image was like 10GB, and it was slow af.
The VirtualBox machine wasn't created by me, but it was just given to me by a previous developer, so I just had to imagine what I needed and pick up the pieces. In few hours I was ready with my Dockerfile.
So I tried it, and....... obviously it didn't work. I entered inside my container and I tried to manually execute commands in order to see where it breaks, and I tried to fix each of them. They were just the usual Linux dependencies problems, incompatibility among libraries, and so on.
Putting everything in order, I started over again with a virgin Ubuntu image, and I tried to fix every single error that appeared, I typed something like 1 hundred commands just to have my development machine up and running.
Now I have a running container that works, I don't know how to reproduce it with a Dockerfile, and I don't know what I'm supposed to do with it, because I'm afraid that any wrong command could destroy the container and lose all the job I did. I can't even bind folders because start/exec doesn't support bindings, so I've to copy files.
Furthermore, the documentation about start/exec is very limited, and every question on StackOverflow just talks about deployment. So am I wrong? Did I use containers for something that wasn't their main purpose? What am I supposed to do now? I'm lost, I feel so much stupid.
Just tell me what to do or call a psychologist8 -
Need advice about protecting ddos via iptables and whitelisting. Currently I launched my gameserver and am fighting against a massive attack of botnets. Problem was solved by closing all ports on my gameserver linux machine and shipping game.exe with injected c++ socket client. So basically only gamers who launch my game exe are being added to firewall iptables via the socket client that is provided in the game exe. If some ddosers still manage to get inside and ddos then my protection is good enough to handle attacks from whitelisted ips from inside. Now I have another problem. Lots of players have problems and for some reason shipped c++ client fails to connect to my socketserver. Currently my solution was to provide support in all contact channels (facebook,skype,email) and add those peoples ips to whitelist manually. My best solution would be to make a button in website which you can click and your ip is whitelisted auromatically. However if it will be so easy then botnets can whitelist themselves as well. Can you advice me how I could handle whitelisting my players through web or some other exe in a way that it cant be replicated by botnets?1
