So, I needed a package installed on one of our Unix servers. The package manager--which is obsolete garbage--was failing with a message which can only be described as a variant of "Go fuck yourself". A quick Google search didn't help.
3 espressos and an eternity later, I have descended into a manic state. My hair has turned grey and I have started lactating. As a last-ditch effort, I try a new search query on Google, and the first link takes me to a forum with a thread discussing a similar issue. The last post in the thread has a solution which works for me. After fixing the issue, everything in the world feels right and I decide to thank the generous poster, who is like an angel to me at this point.
Guess what? The poster is none other than me. 8 months back, I had created a user account on the forum just to post the solution to a similar issue I had on another server.13 -
If Operating Systems Ran The Airlines
UNIX Airways
Everyone brings one piece of the plane along when they come to the airport. They all go out on the runway and put the plane together piece by piece, arguing non-stop about what kind of plane they are supposed to be building.
Air DOS
Everybody pushes the airplane until it glides, then they jump on and let the plane coast until it hits the ground again. Then they push again, jump on again, and so on ...
Mac Airlines
All the stewards, captains, baggage handlers, and ticket agents look and act exactly the same. Every time you ask questions about details, you are gently but firmly told that you don't need to know, don't want to know, and everything will be done for you without your ever having to know, so just shut up.
Windows Air
The terminal is pretty and colorful, with friendly stewards, easy baggage check and boarding, and a smooth take-off. After about 10 minutes in the air, the plane explodes with no warning whatsoever.
Windows NT Air
Just like Windows Air, but costs more, uses much bigger planes, and takes out all the other aircraft within a 40-mile radius when it explodes.
Linux Air
Disgruntled employees of all the other OS airlines decide to start their own airline. They build the planes, ticket counters, and pave the runways themselves. They charge a small fee to cover the cost of printing the ticket, but you can also download and print the ticket yourself. When you board the plane, you are given a seat, four bolts, a wrench and a copy of the Seat-HOWTO.html. Once settled, the fully adjustable seat is very comfortable, the plane leaves and arrives on time without a single problem, the in-flight meal is wonderful. You try to tell customers of the other airlines about the great trip, but all they can say is, "You had to do what with the seat?"11 -
Girlfriend (art student): “You’re in CS. Why don’t you use Windows? Macs are terrible for programming.”
Me: “macOS is better for doing command line compilation and shit because it supports Unix terminal commands and stuff with a reliable OS that’s better-supported than most Linux OSes. I also have Windows on my laptop too, for Visual Studio.”
Girlfriend: “Only like 1% of people use command line stuff. Windows is better for programming. I’ve seen a lot of CS majors use Windows.”
Me: “Uh. You watch me use my computer every day. The stuff I do in Terminal takes forever on Windows.”
Girlfriend: “Yeah, but Windows is just better for programming though.”

Client: "Do you think we could finish specs in week 33, see a demo in week 35, and aim for the product to be finished in week 39?"
I jump on the conference room table, rip the shirt off my sweaty chest, and yell:
"WEEKS OF WHAT? 31 WEEKS SINCE YOU BECAME A CLIENT, 35 WEEKS FROM NOW, 39 WEEKS INTO THE PREGNANCY? BLOODY FUCKING HELL MAN, DO YOU HAVE TO TALK LIKE A RETARD?"
Client, unfazed: "Weeks since the start of the year, sir"
Me, swinging my pants above my head like a lasso:
"WHAT THE FUCK KIND OF SNOWFLAKE ARE YOU, YOU REALLY EXPECT ME TO COUNT THE WEEKS SINCE THE START OF THE YEAR? WHAT ABOUT JUST USING DAY OF THE MONTH YOU OBNOXIOUS DIMWIT?"
Client: "We always use weeks at our company to plan things"
Me, winding the legs of my pants around the neck of the client:
"I HATE IT WHEN PEOPLE USE WEEKNUMBERS, JAKE. I. FUCKING. HATE. IT."
Client, still pretending everything is fine: "If you want I could send you a screenshot of my outlook calendar?"
Me, sitting in underpants on the client's back, sweaty legs wrapped around his waist, trying to pull out his gel-infested manager-hair while strangling him with my pants:
"TIME OF DEATH, UNIX TIMESTAMP 1595240810, ISO 8601 DATE 2020-07-20T10:26:50+00:00. ANOTHER PROJECT SUCCESSFULLY WRAPPED UP"

Sharing a short story.
Time: 1:30 am
Conversation between me and a night watchman in my society.
I was walking and this watchman suddenly stopped me and started asking questions.
Watchman: Isn't it late at 1:30am. When do u sleep?
Me: I sleep very late (replied in a very uninterested manner)
Watchman: Which year are you?
Me: Final year of Graduation
Watchman: Which branch?
Me: (a bit annoyed now) Software Engineering
Watchman: So you know programming?
Me: (little shocked that he knows what's programming) Learning
Watchman: So, do your university teaches C, Python and UNIX?
Me:(completely shocked by his knowledge) Yup. Except UNIX, others yes.
Watchman then asked some fees related questions and placements scope.
I was annoyed when he approached me for a little talk.. But had a wonderful experience talking to this person. It's great when you meet such unexpected person having such knowledge.
When I asked him how he knows all these, he said he talks like this to many students and learnt it.
His last line to me when I said that you know a lot, was:
Sir, you are the ocean, I am a needle in it.
Truly awesome moment... Never judge anyone by looks or his occupation... Knowledge is something that anyone anywhere can gain...
Respect to that watchman...5 -

curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line
tldr
do curl cht.sh/go/execute+external+program to see how to execute external program in go
And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?
I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.
Nowadays you probably know, how to check the weather from the command line, but if not:
curl wttr.in
or
curl wttr.in/Paris
(curl wetter in Paris if you want to know the weather in Paris)
After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):
curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text
And now last but not least, the gem in this collection: cheat.sh.
The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.
With cheat.sh you don't need to install anything, just do:
curl cheat.sh/tar (or whatever)
you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).
But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.
Now you can simply do:
curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read
or even
curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件
and get your question answered
(cht.sh is an alias for cheat.sh).
And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.
One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.
The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.
The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh
What do you think about this service?
What do you think about this approach?
Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?

My school computers are *the most secure machines* on the planet as per the network admins at school.
A simple Unix command like sudo -i allows you to break in the system with "root" as password.
Pretty secure, right?3 -
fork() can fail: this is important
Ah, fork(). The way processes make more processes. Well, one of them, anyway. It seems I have another story to tell about it.
It can fail. Got that? Are you taking this seriously? You should. fork can fail. Just like malloc, it can fail. Neither of them fail often, but when they do, you can't just ignore it. You have to do something intelligent about it.
People seem to know that fork will return 0 if you're the child and some positive number if you're the parent -- that number is the child's pid. They sock this number away and then use it later.
Guess what happens when you don't test for failure? Yep, that's right, you probably treat "-1" (fork's error result) as a pid.
That's the beginning of the pain. The true pain comes later when it's time to send a signal. Maybe you want to shut down a child process.
Do you kill(pid, signal)? Maybe you do kill(pid, 9).
Do you know what happens when pid is -1? You really should. It's Important. Yes, with a capital I.
...
...
...
Here, I'll paste from the kill(2) man page on my Linux box.
If pid equals -1, then sig is sent to every process for which the calling process has permission to send signals, except for process 1 (init), ...
See that? Killing "pid -1" is equivalent to massacring every other process you are permitted to signal. If you're root, that's probably everything. You live and init lives, but that's it. Everything else is gone gone gone.
Do you have code which manages processes? Have you ever found a machine totally dead except for the text console getty/login (which are respawned by init, naturally) and the process manager? Did you blame the oomkiller in the kernel?
It might not be the guilty party here. Go see if you killed -1.

A group of Security researchers has officially fucked hardware-level Intel botnet officially branded as "Intel Management Engine" they did so by gathering it all the autism they were able to get from StackOverflow mods... though they officially call it a Buffer Overflow.
On Wednesday, in a presentation at Black Hat Europe, Positive Technologies security researchers Mark Ermolov and Maxim Goryachy plan to explain the firmware flaws they found in Intel Management Engine 11, along with a warning that vendor patches for the vulnerability may not be enough.
Two weeks ago, the pair received thanks from Intel for working with the company to disclose the bugs responsibility. At the time, Chipzilla published 10 vulnerability notices affecting its Management Engine (ME), Server Platform Services (SPS), and Trusted Execution Engine (TXE).
The Intel Management Engine, which resides in the Platform Controller Hub, is a coprocessor that powers the company's vPro administrative features across a variety of chip families. It has its own OS, MINIX 3, a Unix-like operating system that runs at a level below the kernel of the device's main operating system.
It's a computer designed to monitor your computer. In that position, it has access to most of the processes and data on the main CPU. For admins, it can be useful for managing fleets of PCs; it's equally appealing to hackers for what Positive Technologies has dubbed "God mode."
The flaws cited by Intel could let an attacker run arbitrary code on affected hardware that wouldn't be visible to the user or the main operating system. Fears of such an attack led Chipzilla to implement an off switch, to comply with the NSA-developed IT security program called HAP.
But having identified this switch earlier this year, Ermolov and Goryachy contend it fails to protect against the bugs identified in three of the ten disclosures: CVE-2017-5705, CVE-2017-5706, and CVE-2017-5707.
The duo say they found a locally exploitable stack buffer overflow that allows the execution of unsigned code on any device with Intel ME 11, even if the device is turned off or protected by security software.
For more of the complete story go here:

Hello there, just couple of words about PHP. I've been develop on PHP more than 10 years, I've seen it all 3,4,5,{6},7. Yes PHP was not good in terms of engineering and patterns, but it was simple, it was the most simple language for web to start those days. It was simple as you put code into file, upload it via FTP and it works. No java servlets, no unix consoles, no nothing, just shared hosting account was enough to host site, or even application with database. As database everybody used to have mysql, again because its simple to start and easy to maintain. So PHP+MySQL became industry standard on Web during 00-2012, and continues in some way.
You can write HTML and logic inside single file, within php code, even more single file may content few pages, or even kind of framework. That simplicity and agility sticks everybody who wants to develop sites with PHP.
This is pretty much about why it is so popular.
Each good or wannabe PHP developer in an early days write its own framework or library (like in javascript this days because of nodejs)
Imagine that PHP has hadn't have package manager, developers used to have host packages on their own sites, then various packages catalog sites created, and then finally composer. A gazillions of php code had spread over internet, without any kind of dependency control. To include libraries to your projects you have to just write include, or require. Some developers do it better than others.
So what we have ? A lots of code, no repositories, zip archives with libraries, no dependency control.
Project that uses that kind of code are still alive even today, they are solid hose of cards, and unmaintainable of course.
And main question that I'm trying to answer is Why PHP is not good ?
- First is amount of legacy code which people copy and pasted into their project, spread it even more like a virus.
- Lack of industry standards at the beginning lead to a lots of bad practices among developers. PHP code usually smells.
open source php projects in early days was developed in same conditions so even in phpbb, phpnuke, wordpress, drupal used to have a lot of bad practices in their codebase. So php developers usually not study by another library, instead they write their own frameworks/libraries.
- "It works", - there are no strong business demands, on web development, again because lack of standards, and concerns.
This three things are basically same, they linked to each other and summarize of answer of why PHP have strong smells and everybody yelling against it.
Whats is with PHP nowadays ? Of course PHP today is more influenced by good practice of webdev. Composer, Zend, Laravel, Yii, Symphony and language it self became more adult so to say, but developers...
People who never tried anything except PHP are usually weaker in programming and ecosystem knowledge than people who tried something else, python, perl, ruby, c for instance.
Summary
PHP as any other programming language is a tool. Each tool has its own task. Consider this and your task requirements and PHP can be just good enough solution.
"PHP is shit" - usually you heard that from people who never write strong applications on PHP and haven't used any good tools like Symphony or Laravel.
Cheap developers, - the bigger community, the more chance to hire cheap developers, and more chance to get bad code. That can be applied on any other language.
PHP has professionals developers, usually they have not only php on scope.
That's all folks, this is very brief, I am not covering php usage early days in details, but this is good enough to understand the point.

Got a call from Google!
Asked for two months to study: Discrete mathematics, Calculus, introductions to algorithms, design patterns, CTCI and linux/unix OS workings in general.
I know I'll be banging my head against the wall and I don't have my expectations too high. But regardless I feel like this is a good excuse to speed up my studies and push myself in the direction I want to go already. It'll be a win-win even if I don't land the position because I'll definitely gain a ton in the process of preparing.
I will be expose to all of this material (except for calculus because I've been learning it for a couple of months) for the first time so I know it'll be a challenge and I am looking forward to it.
If any of you have any tips on good study habits that'll be much appreciated; I currently like to read most of my material and supplement with videos/tutorials... Khan is great but they lack material on discrete mathematics unfortuantely. Thanks in advance!
Wish me luck (:9 -
Today I learned what GNU acronym stands for:
GNU = GNU's Not Unix!
😂 why doesn't Computer Science have more acronyms like that?14 -
I love how the Keybase Linux client installs itself straight into /keybase. Unix directory structure guidelines? Oh no, those don't apply to us. And after uninstalling the application they don't even remove the directory. Leaving dirt and not even having the courtesy to clean it up. Their engineers sure are one of a kind.
Also, remember that EFAIL case? I received an email from them at the time, stating some stuff that was about as consistent as their respect for Unix directory structure guidelines. Overtyping straight from said email here:
[…] and our filesystem all do not use PGP.
> whatever that means.
The only time you'll ever use PGP encryption in Keybase is when you're sitting there thinking "Oh, I really want to use legacy PGP encryption."
> Legacy encryption.. yeah right. Just as legacy as Vim is, isn't it?
You have PGP as part of your cryptographic identity.
> OH REALLY?! NO SHIT!!! I ACTIVELY USED 3 OS'S AND FAILED ON 2 BECAUSE OF YOUR SHITTY CLIENT, JUST TO UPLOAD MY FUCKING PUBLIC KEY!!!
You'll want to remove your PGP key from your Keybase identity.
> Hmm, yeah you might want to do so. Not because EFAIL or anything, just because Keybase clearly is a total failure on all levels.
Written quickly,
the Keybase team
> Well that's fucking clear. Could've taken some time to think before hitting "Send" though.
Don't get me wrong, I love the initiatives like this with all my heart, and greatly encourage secure messaging that leverages PGP. But when the implementation sucks this much, I start to ask myself questions about whether I should really trust this thing with my private conversations. Luckily I refrained from uploading my private key to their servers, otherwise I would've been really fucked.1 -
Been reading devRant for a while now and I have to say I'm sad about the way the future of the software engineering looks like. Everyone seems to have a lot of hatred towards certain techniques and/or platforms and sad to say, but you are missing a lot.
I have been in the biz for around 15 years and have worked on Win, Linux, Mac, Unix, Symbian, Embedded etc. using all sorts of tools and languages and I must say it has taught me a lot and given diversity on my career and I hope you could also open your mind and start educating yourselves. Theres a world behind your bubble!
Peace and love!13 -
Back in my sysadmin days we had an IT zoo to look after. And I mean it... Linux side was allright, but unix.... Most unices were no longer supported. Some of their vendors' companies were already long gone.
There was a distant corner in our estate known to like 2 people only, both have left the company long ago. And one server in that corner went down. It took 2 days to find any info about the device. And connecting to it looked like:
1 ssh to a jumpbox #1
2 ssh to a jumpbox #2
3 ssh to a dmz jumpbox
4 ssh to an aix workload
5 fire up a vnc server
6 open up a vnc client on my workstation, connect to than vnc server [forgot to mention, all ssh connections had to forward a vnc port to my pc]
7 in vnc viewer, open up a terminal
8 ssh to hp-uxes' jumpbox
9 ssh to the problematic hp-ux

Yknow what the best part about Unix is? (Not Linux. Like old school Unix. AIX, HPUX, or in this specific case: Solaris)
It never needs to be updated. like ever. Even when new features are added 5 years ago to add features that GNU has had for literally decades. Updates are for the weak. Because why should I be able to type "netstat -natup" when instead you can enjoy several hours of developing the nightmare one-liner that is:
Pfiles /proc/* | awk '/^[0-9]/ {p=$0} /port/ {printf "%.4s %-30s %-8s %s\n", $1,$3,$5,p}' 2>/dev/null
Isn't that just so much more fun?!
Thanks guys. I'm going back to GNU now if you don't mind.6 -

I've never used Windows in my day-to-day life. No kidding.
When I got my father's first computer, I used an old distribution called BBC Linux. I didn't have any computer knowledge, it was my first contact with a computer, so I went to a friend's house and asked for a CD to install on my computer. I don't know if this friend ended up making a "gotcha" and thought I'd give up, but I just read the manuals and fell in love. That was year 2000.
Then I used Conectiva Linux, then I went to Red Hat 9, then Slackware, then in 2007 I started using Solaris. And I stayed on Solaris (Solaris 10, Solaris Nevada and OpenSolaris) until 2011.
In 2011 I bought a Mac. I stayed at Apple until 2020, when I couldn't stand Apple forcing me to buy new computers (I still don't understand how a 2011 iMac, i5 (4 Hyper Thread cores) with 16GB of RAM, 1TB SSD only runs up to High Sierra).
Then I bought a Dell. It came with Windows 10, the first thing I did was install WSL2. I could not stand it, the system is bad, sorry. I installed OpenSuse and have been using it for two years.
It's just that every day someone tells me "how can you use this"? "There is no alternative to Windows, do you want to be different?"
I know that my story was the reverse of the "mainstream", so I'm going to talk about my vision of Windows, that in my brain it is actually the "alternative".
- Having a file explorer without "tabs" in 2022 is unthinkable for me.
- I love terminal. And the Windows terminal is very limited. "ps ... | awk ... | xargs ..." is a must for me. "find ./ -name '...' -exec ..."... these things on Windows are totally "different" and have the "powershell way" while all other operating systems keep the same form. And cygwin is not an option. As Wine for serious work is also not.
- Dragging a file into the terminal, and having it write its path, is so natural, that when Windows didn't do it, I was dismayed.
- I've always used StarOffice, OpenOffice and now LibreOffice. All the people in my story received my documents and reports as a PDF and no one complained. Until a coworker saw me editing in LibreOffice and said "oh I want it in word format". As long as he didn't know, everything was fine, right?
- Windows is paid. And is there advertising? I don't understand. And I refuse. If you want to display advertising, then excuse me. I have no problem paying, I'm not an opensource shiite. It's just that paying and not working bothers me much more than an opensource that I can fix or expect a fix knowing the good will of the people involved.
- Hyper-V is a joke. QEMU/KVM is better, and Bhyve on FreeBSD which is a very young project, is already a million times better than Hyper-V.
- Developing in C/C++ for Windows is only possible in two ways: Either you've always lived in Windows and your brain is conditioned, or you compile with MSYS2 (CLang or GCC).
- There is no significant evolution of the windows desktop since 95.
- Multiple workspace support with multiple monitors, not ready. It's another joke.
- REGEDIT does not need any comment.
- The system loses performance over time. I still don't know how Windows achieves this.
- I've seen people complain about desktop fragmentation on Unix and Linux. Many DEs end up leaving applications with different themes (like running a Qt application in Gnome and GTK in KDE), but to be quite honest, the lack of Windows standard bothered me much more. Even Microsoft's own software is completely different: Control Panel, Calculator, Paint and Office, To-Do, and Settings, have horrible style differences and look-and-feel fragmentation.
- Dark mode has not been implemented. It's another joke. Many applications are white while everything else is dark. Sorry, even on Linux which is a mess, this has been resolved. And well resolved.
- NTFS? Serious?
- C:, D:.. It doesn't convince me since DOS.
- Bloatware.
- News "biased" in the search bar is a lack of respect for those who use the computer to work.
And that. For me, Windows is the alternative operating system. I can't take Windows seriously, for me it's an experimental one like Haiku or ReactOS. It's good to play.
About market share, it doesn't convince me to use it. But convinces me to sell. I've always developed applications to run on Windows. And when I need it, I turn on a VM to compile the project. But in everyday life? Impractical.15 -
I previously worked as a Linux/unix sysadmin. There was one app team owning like 4 servers accessible in a very speciffic way.
* logon to main jumpbox
* ssh to elevated-privileges jumpbox
* logon to regional jumpbox using custom-made ssh alternative [call it fkup]
* try to fkup to the app server to confirm that fkup daemon is dead
* logon to server's mgmt node [aix frame]
* ssh to server directly to find confirm sshd is dead too
* access server's console
* place root pswd request in passwords vault, chase 2 mangers via phone for approvals [to login to the vault, find my request and aprove it]
* use root pw to login to server's console, bounce sshd and fkupd
* logout from the console
* fkup into the server to get shell.
That's not the worst part... Aix'es are stable enough to run for years w/o needing any maintenance, do all this complexity could be bearable.
However, the app team used to log a change request asking to copy a new pdf file into that server every week and drop it to app directory, chown it to app user. Why can't they do that themselves you ask? Bcuz they 'only need this pdf to get there, that's all, and we're not wasting our time to raise access requests and chase for approvals just for a pdf...'
oh, and all these steps must be repeated each time a sysadmin tties to implement the change request as all the movements and decisions must be logged and justified.
Each server access takes roughly half an hour. 4 servers -> 2hrs.
So yeah.. Surely getting your accesses sorted out once is so much more time consuming and less efficient than logging a change request for sysadmins every week and wasting 2 frickin hours of my time to just copy a simple pdf for you.. Not to mention that threr's only a small team of sysadmins maintaining tens of thousands of servers and every minute we have we spend working. Lunch time takes 10-15 minutes or so.. Almost no time for coffee or restroom. And these guys are saying sparing a few hours to get their own accesses is 'a waste of their time'...
That was the time I discovered skrillex.4 -
Master Foo and the Script Kiddie
(from the Rootless Root Unix Koans of Master Foo)
A stranger from the land of Woot came to Master Foo as he was eating the morning meal with his students.
“I hear y00 are very l33t,” he said. “Pl33z teach m3 all y00 know.”
Master Foo's students looked at each other, confused by the stranger's barbarous language. Master Foo just smiled and replied: “You wish to learn the Way of Unix?”
“I want to b3 a wizard hax0r,” the stranger replied, “and 0wn ever3one's b0xen.”
“I do not teach that Way,” replied Master Foo.
The stranger grew agitated. “D00d, y00 r nothing but a p0ser,” he said. “If y00 n00 anything, y00 wud t33ch m3.”
“There is a path,” said Master Foo, “that might bring you to wisdom.” The master scribbled an IP address on a piece of paper. “Cracking this box should pose you little difficulty, as its guardians are incompetent. Return and tell me what you find.”
The stranger bowed and left. Master Foo finished his meal.
Days passed, then months. The stranger was forgotten.
Years later, the stranger from the land of Woot returned.
“Damn you!” he said, “I cracked that box, and it was easy like you said. But I got busted by the FBI and thrown in jail.”
“Good,” said Master Foo. “You are ready for the next lesson.” He scribbled an IP address on another piece of paper and handed it to the stranger.
“Are you crazy?” the stranger yelled. “After what I've been through, I'm never going to break into a computer again!”
Master Foo smiled. “Here,” he said, “is the beginning of wisdom.”
On hearing this, the stranger was enlightened.2 -
In college when we had programming labs where we had to use the schools unix server to compile and run.
My professor was very bad at explaining what actually needed to be done in the labs to the point where even the TAs didn't know what to do.
We were suppose to write an application in C to find out by "trial and error" how large we could make an array (or something like that, it's been too long). This not being explained well and no one knowing that much about C, I wrote a loop that just kept growing an array until it couldn't anymore. I watched it consume 72GB or memory from the servers before quitting the loop and realizing with the TA what the professor really meant.
I now feel bad for the IT staff monitoring the system wondering where 72GB just went...2 -
I own my grandfather's Victorinox Swiss Army Knife, probably from the eighties. I absolutely love it — it's just like the standard Unix toolkit. Minimalist, multi-purpose, efficient. This is what I have in my knife:
1. Two blades. I call them master (yes) and slave
2. Corkscrew. I call it "ed".
3. Hole puncher, but not just any hole puncher. Mine has an angular sharp edge to carve holes instead of just punching them. Super efficient for wood, plastic and thick fabric. It also has a hole so it can be used as a needle. I call it "vi".
4. Bottle opener which is also a screwdriver. I call it "more".
5. Can opener. This is my favorite one.
It can help you open just about anything. Any type of cans, closed pistachio nuts, oysters, your barely legal girlfriend's virginity — anything. When I eat pistachios, I'm holding my Victorinox in my hand opening tough ones with the speed of rm -rf ripping through your files. Oh, and it's also another screwdriver. I call it "cat".
But let's take a look at modern Victorinox. Maybe it's better? No, not at all. It's totally metrosexual featuring nail files, nail clippers, nail scissors and a flash drive (not even a good one).
Newer doesn't always mean cooler.
(I have the exact same one, photo from the internet because I'm too lazy)

List of shit my superior said and wrote in the project:
1. Prefer to write "pure" SQL statement rather than ORM to handle basic CRUD ops.
2. Mixing frontend and backend data transformation.
3. Dump validation, data transformation, DB update in one fucking single function.
4. Calculate the datetime manually instead of using library like momentjs or Carbon.
5. No version control until I requested it. Even with vcs, I still have to fucking FTP into the staging and upload file one by one because they don't use SSH (wtf you tell me you don't know basic unix command?)
6. Don't care about efficiency, just loop through thousands of record for every columns in the table. An O(n) ops becomes O(n * m)
7. 6MB for loading a fucking webpage are you kidding me?
Now you telling me you want to make it into AJAX so it'll response faster? #kthxbye2 -
Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.
Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".
The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.
Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.
And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.
The resulting command that you end up picking is something that you'll probably forget in the next hour.
I like a good challenge, but readability is important too.
Or maybe I have very rudimentary shell skills.5 -
Hello fellow coders can you help me here plz.
I'm really confused whether to buy MACBOOK PRO 13 INCH or SURFACE PRO 4. Both of i5/8gbRam/256ssd specs. Price almost same in India.
My main use is programming ( web apps/ open source) + portability.
Factors I like in macbook pro:
1) unix based
2) best service here in India ( heard from answers on Quora )
3) DURABILITY ( heard from answers on Quora ) ( will last for many years without any glitch).
Factors I like in Surface pro 4:
1) its ultraportability
2) pen & touch
3) better typing experience ( since I code/blog for long hours)
4) native bash support
5) sexier than MBP :P
I really like SP4 over MBP but I'm worried about its durability and service(in India).
What are your thoughts on this guyz?

Don’t teach with LOGO, but instead start with Scratch, then something more advanced like Python and after that maybe C# or Java.
Teach different operating systems and software, not only Windows and Microsoft Office. There should be class with Linux (Mint for instance) with LibreOffice and another with macOS and iWork.
Teach basic troubleshooting steps.
Less theory, more practice.
STOP BEING SUCH MICROSOFT ORIENTED.
Ability to use own laptop (I would be really happy to use my own one).
Teach basic commands for Windows and Unix based systems.
Teach how to install Windows and Linux.3 -
Why the fuck don't you provision and configure the cloud virtual machine yourself, "web lead" guy who uses fucking WINDOWS to develop software? Why don't you install Webmin and PHPMyAdmin in the VM yourself if you like GUIs so much? Why do I have to configure Apache and MySQL and fix all sorts of little issues for your project just so you can use some shitty CMS? I'm not your fucking IT support guy. Go learn how to use Unix, take responsibility for your shit, and let me spend my time actually developing software.9

Hi, my name is bohr and I'm a recovering distro hopper.
It all started with Ubuntu, out of my frustrations with the unintuitive nature of DOS I gravitated to a Unix environment which Ubuntu naturally solved. But I quickly became annoyed with the laggy nature of it's daily usage. So I switched to Linux mint. Loving the HTML/css/js configuration aspect of cinnamon I thought it was the answer to all my problems. But I became annoyed with apt and it's lack of a few programs I wanted. This got me to look into an arch based distro, because pacman seemed like the answer to my problems. Unfortunately there are way too many arch distros to use. I experimented with antegros' many DE options: gnome, kde, i3, deepin, openbox... Always finding something wrong. I tried manjaro and it's many flavors, still being annoyed with minute aspects of the os. Out of frustration, with the deep configuration settings I was getting into and the need to actually focus on the work being done on the computer I crawled back to Linux mint. But now my friends, I have decided that maybe it's time to just use a more established distro? Maybe gnome isn't actually that bad? Maybe I need to give it another try? And that is why, I promise, this is the last hop for me. Arch Linux, Gnome here I come and I'm ready to commit this time!...
But have you guys seen POP!_OS? Woah, I bet it would solve all of my problems....6 -
I've been using the Square REST API and I spent one hour thinking there was something wrong in my code until I f** found that THEY were not following OAuth 2 guidelines, which made their workflow incompatible with the OAuth lib I was using, so I had to mark an exception for Square's OAuth from the rest of my OAuths. Specifically, RFC 6749 Section 4.2.2 and 5.1.
However, after reading OAuth 2 guidelines, I became angry at THEM instead. The parameter `expires_in` should be the "lifetime in seconds" after the response. This will always be innevitably inaccurate, since we are not taking into account the latency of the response. This is, however, not a huge problem, since the shortest token lifetimes are of an hour (like f** Microsoft Active Directory, who my cron jobs have to check every ten minutes for new access tokens). Many workflows (like Microsoft, Square, and Python's oauthlib) have opted to add the `expires_at` parameter to be more precise, which marks the time in UTC. However, there's no convention about this. oauthlib and Microsoft send the time in Unix seconds, but Square does this in ISO 8601. At this point, ISO 8601 is less ambigious. Sending a raw integer seems ambiguous. For example, JavaScript interprets integer time as Unix _milliseconds_, but Python's time library interprets it as _seconds_. It's just a matter of convention, a convention that is not there yet.
Hope this all gets solved in OAuth 2.1 pleeeaasseee

Ah, the little subtle things we have to iron out as we progress from Junior Developer to Medior Developer.. things like:
- knowing the difference between a carriage return and a line feed (although having worked with analog typewriters helps) and later knowing that Unix-based systems and Windows NT-based systems implement it differently..
- knowing that serialization is important because not all computers interpret data the same way and some computers allocate 4 Bytes for a construct, others 16 Bytes.. and then we get the funkiness of transferring character sets between machines..
- knowing that a whitespace character is not only an actual space (as is known in ASCII as code 32). This one can cause even medior developers a headache, as in: why the fuck does this string function say that "hello I am a duck" and "hello I am a duck" are not the same?! Turns out then in the debugger that when you expand every character in the string you see that string1 contains 32 32 32 32 as usual.. but then string2 contains -96 -96 -96 -96 and you're like.. what the fuck..? Then you know you have to throw \\h regex at it. Haha.
- finalizing our objects and streams (although modern languages do that for us).. otherwise we have to do funky shit like trying to find what's locking a file, which is not so easy to figure out.
- figuring out why something won't work often requires you to not only break down the problem in smaller steps, to use a debugger, but sometimes it's even better to just create a proof of concept, slap some minimal code in there and debug that.. much easier.
- etc.

Since my first post was a success, here's another shameless hack-- in this case, ripping a "closed" database I don't usually have access to and making a copy in MySQL for productivity purposes. That was at a former job as an IT guy at a hardware store, think Lowes/Rona.
We had an old SCO Unix server hosting Informix SQL (curious, anyone here touched iSQL?), which has terminal only forms for the users to handle data, and has keybindings that are strangely vi based (ESC does commit changes. Mindfsck for the users!). To add new price changes to our products, this results to a lengthy procedure inside a terminal form (with ascii borders!) with a few required fields, which makes this rather long. Sadly, only I and a colleague had access to price changes.
Introducing a manager who asks a price change for a brand- not a single product, but the whole product line of a brand we sell. Oh and, those price changes ends later after the weekend (twice the work, back at regular price!)
The usual process is that they send me a price change request Excel document with all the item codes along with the new prices. However, being non technical, those managers write EVERYTHING at hand, cell by cell (code, product name, cost, new price, etc), sometimes just copy pasted from a terminal window
So when the manager asked me to change all those prices, I thought "That's the last time I manually enter all of this sh!t- and so does he". Since I already have a MySQL copy of the items & actual (live) price tables, I wrote a PHP backend to provide a basic API to be consumed to a now VBA enhanced Excel sheet.
This VBA Excel sheet had additional options like calculating a new price based on user provided choices ("Lower price by x $ or x %, but stay above cost by x $ or x %"), so the user could simply write back to back every item codes and the VBA Excel sheet will fetch & display automatically all relevant infos, and calculate a new price if it's a 20% price cut for example.
So when the managers started using that VBA sheet, I had also hidden a button which simply generate all SQL inserts for the prices written in the form, including a "back to regular price" if the user specified an end date, etc.
No more manual form entry for me, no more keyboard pecking for the managers with new prices calculated for them. It was a win/win :)1 -
Way back, 20 or so years ago, when I went to the university, every student got an account so that we could work with the Unix machines. Every user got the same default password, -apollo-, still remember it until today, and one day I felt a little bit evil and I tried to login to the administrator account, of course the first password I tried was the default password and it worked!!! I got super scared and told an older student about it, who was brave enough to scare the administrators a little bit by leaving a message like "you have been hacked!!!" or something similar. I was just too scared to do anything about it. All I wanted to do was see IF I could login ☺️ my few minutes of being Mr. Robot... Guess hacking was not for me 😃

I've been laughed at a lot for thinking this way, but I'm honestly frustrated by how little information exists on the web for people who want to take Operating System development a step further. I mean, the OSDev Community is amazing and offers pretty, much everything one needs to know at the system level. But my issue is: What if someone didn't want to use existing compilers and assemblers like GCC and NASM, and do everything from total scratch? I mean, the original Unix came from somewhere, right? I know you're going to think "Why not? It works.". Well, I just think it's crazy how few people (such as Linus and the GNU foundation) are out there that have the ability to create such things without help from existing software tools. Sure, it could take me decades of careful practice and experience, but my passion is for creating software at this level and becoming one of those people is very strong. I just wish I knew where to begin and who to learn from.4

Avoid ACPICA if at all possible. It's one garbage tier cluster fuck of bad design, horrible documentation and downright misleading and wrong code
It's meant to consist of an ASL compiler, disassembler, debugger, dumper, various user space utitilies and a kernel resident OSPM implementation *if* you can figure out what belongs to what. Even just compiling this pile of trash is a mystery in itself. Think you need the source files in source/common? EEEEH, wrong. Well, at least partially since most of them seem to be for the user space stuff..? Other ones *are* needed on the other hand. At least the disassembler and/or debugger and/or dumper components seem to reference them. Not that I could figure out how to compile those anyways. The real path to your goal seems to be to ignore a seemingly arbitrary subset of source and header files until your linker stops complaining
There's also a bunch of configuration defines, some of which *you* define, some defined *for* you, based on again others. Of course most of them do stupid shit. Enabling the debugger automatically enables debug logging. Enabling the disassembler force enables debug allocation tracking... What?
The code itself isn't of much help either. Looking in "os_specific/service_layers" you find what looks to be reference implementations of acpica functions in certain os' like windows and unix. Of course I had a look because AcpiOsReadMemory is supposed to read physical memory and I don't know how I would even implement that. But hey, osunixxf.c (xf for interface... of course) should tell me. I'll let you see for yourself in the attached image. Apparently it does fuck all and just returns AE_OK. No error, no logging, no nothing. Just ok. As you can imagine, AcpiOsWriteMemory doesn't do much more either.
...okay so maybe physical memory accesses aren't actually used and these functions are some sort of relic from past times? Nope! They are absolutely necessary for doing low level device interaction. WTF. So finally I went to the linux source and checked how *they* implemented them, and just as I thought, these functions are anything but no-ops...
...So for what fucking reason do these stupid interface implementations even exist but to purposefully mislead you?? They aren't used for fucking anything! As far as I know Windows doesn't even *use* ACPICA and Linux have their own fork with working implementations... They just sit there, just to tell you how to NOT do it
So that's some of my thoughts about ACPICA. Note that I haven't even used it as a library yet, I just got it to compile and link and it already fucked with me this much.
There's also so much more I didn't mention like that you *have* to modify the acpica source in order to get your own platform header working (else #error) eventhough the docs explicitely instruct you not too but you get the point
Don't use ACPICA if you don't have to. Save your sanity for something that's worth it

Translating win32 calls to whatever the hell there is in Unix and Unix-like OSes (well, most of them) in order to port a certain game net code library and dear god why did I volunteer myself for this task
At least pevents is there to help, but too bad cmake doesn’t want to compile it with the flag I need (“-DWFMO”) in order to make the “WaitForMultipleEvents” method to work at all. Instead no matter what options I give it on the command line or how I tell VS Code to do it, it seems to give me the finger to my fucking face.
Doing it for games on the cooler OSes... doing it for the community... come on...2 -

44 years after Unix, Windows gets sudo. I'm proud of the little guy. He's starting to grow up!22 -
After having my soul suck away by "corporate", I installed VS code on my Windows 10 gaming machine.
Now, I have a pretty hardcore dev setup on my MacOS (it's unix-based and it's good, so stop the hate). I'm talking about fully automatized Rakefile that will provision it from scratch: vim, macvim, tmux, iterm configs, 15+ brew tools, 15+ brew-cask tools, themes, plugins, etc.
Installing VS Code, Node and MongoDB on Windows, just for the fun and giggles, and not having any of my hardcore tools, made me feel like... it's something silly and fun again. I'm once again that softcore developer with no stress and no constant self-reminder to improve workflow effectiveness.
Made me a little happy.

Tl;Dr Im the one of the few in my area that sees sftping as the prod service account shouldn't be a deployment process. And the ONLY ONE THAT CARES THAT THIS IS GONNA BREAK A BUNCH OF SHIT AT SOME POINT.
The non tl;dr:
For a whole year I've been trying to convince my area that sshing as the production service account is not the proper way to deploy and/or develop batch code. My area (my team and 3 sister teams) have no concept of using version control for our various Unix components (shell scripts and configuration files) that our CRITICAL for our teams ongoing success. Most develop in a "prodqa like" system and the remainder straight in production. Those that develop straight in prodqa have no "test" deployment so when they ssh files straight to actual production. Our area has no concept of continuous integration and automated build checking. There is no "test cases", no "systems testing" or "regression testing". No gate checks for changing production are enforced. There is a standing "approved" deployment process by the enterprise (my company is Whyyyyyyyyyy bigger than my area ) but no one uses it. In fact idk anyone in my area who knows HOW to deploy using the official deployment method. Yes, there is privileged access management on the service account. Yes the managers gets notified everytime someone accesses the privileged production account. The managers don't see fixing this as a priority. In fact I think I've only talk to ONE other person in my area who truly understands how terrible it is that we have full production change access on a daily basis. Ive brought this up so many times and so many times nothing has been done and I've tried to get it changed yet nothing has happened and I'm just SO FUCKING SICK that no one sees how big of a deal this. I mean, overall I live the area I work in, I love the people, yet this one glaring deficiency causes me so much fucking stress cause it's so fucking simple to fix.
We even have an newer enterprise deployment. Method leveraging a product called "urban code deploy" (ucd) to deploy a git repository. JUST FUCKING GIT WITH THE PROGRAM!!!!..... IT WAS RELEASED FUCKING 12 YEARS AGO......
Please..... Please..... I just want my otherwise normally awesome team to understand the importance and benefits of version control and approved/revertable deployments2 -
hey guys yesterday I got roasted cuz I was using a pc instead of Mac for development work and this was my reply. For me I don't gonna spend 2000+ $ only for 1 sec faster app loading and only for writing codes if someone willing to spend lot of money then they have completely command on there system Mac is very overpriced and overprotective it doest allow dual boot tell u what Mac sucks in 4k video editing,games,it don't even support maya or 3ds max rendering on Mac is gonna hit you hard , and there is same for linux but because it's free I don't much care about it but it is extremely crash and error prone I've installed Ubuntu nearly 20+ computer and after few days some kind of internal error occurred if u cancelled any ongoing installation it's going to hijack your system not let order program to install unless you manually clean that shit out ,yea Unix systems have bit faster app opening time and I appreciate that .
For nerds like me it's not only about coding stuff I like to do crazy stuffs17 -
Didn't think I had material for a rant but... Oh boy (at least at the level I'm at, I'm sure worse is to come)
I'm a Java programmer, lets get that out of the way. I like Java, it feels warm and fuzzy, and I'm still a n00b so I'm allowed to not code everything in assembly or whatever.
So I saw this video about compilers and how they optimize and move and do stuff with the machine code while generating the executable files. And the guy was using this cool terminal that had color, autocomplete past commands and just looked cool. So I was like "I'll make that for my next project!"
In Java.
So I Google around and find a code snipped that gives me "raw" input (vs "cooked" input) and returns codes and I'm like 😎. Pressing "a" returns 97 (I think that's the ASCII value) and I think this is all golden now.
No point in ranting if everything goes as planned so here is the *but*
Tabs, backspaces and other codes like that returned appropriate ASCII codes in Unix. But in windows, no such thing. And since I though I'd go multiplatform (WORA amarite) now I had to do extra work so that it worked cross platform.
Then I saw arrow keys have no ASCII codes... So I pressed a arrow key and THREE SEPARATE VALUES WERE REGISTERED. Let me reiterate. Unix was pretending I had pressed three keys instead of one, for arrow keys. So on Unix, I had to work some magic to get accurate readings on what the user was actually doing (not too bad but still...). Windows actually behaved better, just spit out some high values and all was good. So two more systems I had to set up for dealing with arrow keys.
Now I got to ANSI codes (to display color, move around the terminal window and do other stuff). Unix supports them and Windows did but doesn't but does with some Win 10 patch...? But when tested it doesn't (at least from what I've seen). So now, all that work I put into making one Unix key and arrow key reader, and same for Windows, flies out the window. Windows needs a UI (I will force Win users, screw compatibility).
So after all the fiddling and messing, trying to make the bloody thing work on all systems, I now have to toss half the input system and rework it to support UI. And make a UI, which I absolutely despise (why I want to do back end work and thought this would be good, since terminal is not too front end).2 -
Compiling on Windows feels like an Internet Browsing Simulator.
Really shows how incredible the central Repository and System Package Managment systems of Unix are.
Now... Back to downloading the remainder of the required libraries.8 -
Without Unix, there would have been no Minix (Tanenbaum et al.) orGNU (Richard Stallman et al.).Without Minix, there would be no inspiration to write Linux. Remember that Linus started his “project” because he didn’t like many of the design decisions Tanenbaum has taken in Minix, including the microkernel. In fact, Linus has tried to submit some changes to the professor and the latter rejected them. So the young chap decided to write his own kernel using his design.Without GNU, there would be no open source tools that Linus himself used to write, compile, test and distribute his project, to become a few years later a global phenomenon. Also, the fact that GNU was already an established Unix clone (minus an operating kernel) at that time helped Linus to focus on the missing part, the kernel. Otherwise, he would not have known where to start.And finally, Unix was the template all of the above (and more) were trying to imitate. Without it, there would have been nothing to clone from.1

semi dev related(later half)
A common and random thought I have:
A lot of units that humans use are either needlessly arbitrary or based on something weird. Like Fahrenheit. That shit is weird! 0°F is the freezing point of a water and salt solution. What a weird fucking thing to use!
But also, I like Fahrenheit more. Probably because it's what I was raised with and switching is tedious (though I'm trying. I'd like to use metric more), but also because one degree F is a smaller, more precise change. You can describe more accuracy without decimals.
On the other hand I prefer metric for length. Centimeters, and centimeters are way more precise and way less confusing than inches and .... 1/8th inches? Who the fuck decided on 1/8ths?!
Which brings me to my common thought:
If you look at a Unix timestamp, you can approximate somewhat when it happened. Knowing the current timestamp and a few reference points you can see RELATIVELY what a epoch stamp translates to. A few days ago, an hr ago, 2014ish.
This leads me to think that if we actually taught from a young age to think in epoch as a unit (not as a replacement to normal date formats but as a secondary at first) that we could just naturally read epoch time in the same manner we read dates like "28/01/2006 14:24:10 UTC"
In your brain you automatically know how old you were when that timestamp happened. What grade/job and where you lived at the time. What season it was. You know how far into the day it was, a little before lunch (or after or whatever, your time zone will vary). Now try with 1138458250. I can usually get roughly the year, and month if I really think about it, but that's it. And it takes much more effort
I'm sure there's other units we could benefit from but epoch is the one that usually brings this to mind for me.13 -
First patch for buildroot submitted and added applied to master!! 😁
I had the impression that git (like, more than "git add ." was just too complicated and that making patches was some sort of dark magic using some obscure unix tools.
Well, it turns out that is actually pretty easy, fun and exhilarating!!
Looking forward to build up until I'm making contributions to the kernel! 🤓 -
Spend hours debugging a python script because tests fail. Turns out ftp (the unix binary) adds CR bytes to every byte in a .gz file that looks like a LF on upload (in test setup). Client and server are both linux. 😭
Yes i know switch to binary mode (that fixed it - why not default??). But still WHY CR? Didn't ask for it. No windows in sight.1 -
Last weak I tried to use Linux Arch on my VM. The only Linux distribution I'm used to is Ubuntu and the fist time I launched Arch I completely forgot that it was " do it yourself ". And that the ISO isn't actually a fancy installer like the Ubuntu one.
So I started following a guide and found out that the arch wiki is actually the way to go.
I searched for 1 hour how to change the keyboard to swiss-french which was actually pretty simple.
After that exhausting research that made me realise how ignorant I am with UNIX universe, I finally tried to install the thing.
When I was done installing, it didn't want to boot after I restarted. I got stuck at the 'Booting...' screen. After a few tries I lost all my energy and motivation.
Tl;dr: Tried Arch Linux, realised I had no idea, gave up after a few tries4 -
Since Friday devRant posts where errors are introduced by very dumb things like commas have stood out to me.
Today's error fix. Line 1352. A string input defined in the spec file was set for 13 length. The body file had 12 dashes to represent this input.
Really, one dash, four days to solve.
Oh and Unix over Windows because my compiler on Windows didn't catch it but the Unix one sure did which is how I found it. -
How do you approach generating "random" unique numbers/strings ? Exactly, when you have to be sure the generated stuff is unique overtime? Eg. as few collisions in future as possible.
Now I don't mean UUIDs but when there is a functionality that needs some length defined, symbol specific and definitely unique data, every time it does it's stuff.
TLDR STORY: Generating 8 digits long numbers so they are (deterministically - wink wink) unique is hard but Format Preserving Encryption saves the day. (for me)
FULL STORY:
I had to deal with both strings and codes today.
One was to generate shortlink word for url, luckily found a library that does exactly this. (Hashids)
BUT generating 8 digits long, somewhat random number was harder then I thought, found out on SO something like "sha256(seed) => bytes => ascii/numbers mangling" but that had a lot of collisions because of how the hash got mangled to actually output numbers and also to fit the length.
After some hours I stumbled upon Format Preserving encryption (pyffx) and man it did what I wanted and it had max 2 collisions in 100k values. Still the solution with this feels hacky af. (encrypting straddled unix timestamp with lots of decimals)6 -
Urgh.. the amount of things you have to know as a developer.. it can get stressful and frustrating sometimes when (in-depth) technology knowledge is demanded from you (for instance, for a job position)..
It's like being a doctor, being a lifelong student.
A few examples of what I had to know during my career:
Java, .NET, Python, PHP, JavaScript/HTML5/CSS3, Sass/Less, Node.js, ReactJS, AngularJS, Vue.js, Cordova, Ionic, Android, design patterns, SOLID, databases (design, implementation, administration, both NoSQL and relational,..), deployment tools (Octopus, Jenkins,..), VCS, CI/CD, HTTP, networking, security (OAuth2, CORS, XSS, CSRF,..), algebra, algorithms, software testing, profiling, Linux, Unix, Windows, MS Office (advanced mail filtering,..), ITIL, IT Law (licensing and its implications when choosing a product, distribution right,..), server architecture,..
Sure yeah, I know, I've studied all that at university but.. it's been too long (almost a decade now). I have to revisit that knowledge.5 -
I want to look a bit into other unix-like operating-systems, apart from Linux, so BSDs and such.
Can any of you tell me, with what or where to start ?4 -
I hate Windows and I hate Dell.
Apple fucking extorts you but at least it fucking works. macOS works, great UI, unix-like, NO FUCKING INTRUSIVE UPDATES
Did your mac break? We'll replaced, no problem.
Fuck, some company should try to be serious competition to Apple. I'd love to see that day, but untill them I unfortunately have to come back to apple, again and again. Fucking shit.16 -
Isn't it ironic that today most of the operating systems are based unix while unix sounds like the word "unique"?1

What are the most common used technologies in workplaces around you?
Everywhere here I see an endless sea of .NET with ocassional streams of Java and some islands of php on IIS or Apache on the server, with ASP/JSP or Angular and jQuery on the client side.
Workstations are 100% Windows(10 or 7, with some legacy XP here and there).
Also most servers run Windows or some Unix version. Linux only for web servers and various system appliances.
Node.js, Ruby on rails, Django/Flask, React.js,Vue.js, Mac/Linux endpoints are only rarely used by fringe hipsters like me and my friends.3 -
Can someone explain linux to me? I can't see through Unix, Linux, GNU, mingw and all those things which somehow seem to be in the same context but i would like a tl;Dr to save my time :)2

Is there anything like React Context or Unix envvars in any functional language?
Not global mutable state, but variables with a global identity that I can set to a value for the duration of a function call to influence the behavior of all deeply nested functions that reference the same variable without having to acknowledge them.13 -
I am stuck on a UNIX legaxy project. This is the perfect time to learn awk, sed, vim. I use them but I wanna get better.
I can read a book, course, but I WANT to write code, maybe something like the hackerrank challenges but harder.
How do I get advanced in awk, sed, vim?6 -
I'm watching the Cybrary Linux+ Cert course and all throughout the lessons the instructor keeps referring to MacOS and Apple related software as being based on Linux. I thought MacOS was built on BSD and Apple software was mostly proprietary but at its core based on open source projects like Bonjour. I'm cringing because I *think* what he means is "Unix-like systems" and I'm a little disturbed that he might not know the difference between BSD and Linux. Maybe it's just for simplicity's sake though... I hope.

Hi fellow DevRanters! I've been studying software engineering for a while now and, while I love programming, I'm starting to think that all I'll be doing as a software engineer now a days is pulling data from a database, sticking it in a nice gui with some buttons and moving on to the next, similar, project. At the same time I am loving linux more and more, I love working with bash and other unix-like tools and I am interested in systems languages like C and Rust. It is for these reasons that I am playing with the idea of switching to Systems and network engineering. What are your thoughts on this? Is Systems and network engineering a field in which I get to program a lot? Will there be more variation in it? Is my view of software engineering completely off? Please share your thoughts and opinions! -
A philosophical question about maintenance/updating.
There is no need to repeat the reasons we need to update our dependencies and our code. We know them/ especially regarding the security issues.
The real question is , "is that indicates a failure of automation"?
When i started thinking about code, and when also was a kid and saw all these sci fi universes with robots etc, the obvious thing was that you build an automation to do the job without having to work with it anymore. There is no meaning on automate something that need constant work above it.
When you have a car, you usually do not upgrade it all the time, you do some things of maintance (oil, tires) but it keeps your work on it in a logical amount.
A better example is the abacus, a calculating device which you know it works as it works.
A promise of functional programming is that because you are based on algebraic principles you do not have to worry so much about your code, you know it will doing the logical thing it supposed to do.
Unix philosophy made software that has been "updated" so little compared to all these modern apps.
Coding, because of its changeable nature is the first victim of the humans nature unsatisfying.
Modern software industry has so much of techniques and principles (solid, liquid, patterns, testing that that the air is air) and still needs so many developers to work on a project.
I know that you will blame the market needs (you cannot understand the need from the start, you have to do it agile) but i think that this is also a part of a problem .
Old devices evolved at much more slow pace. Radio was radio, and still a radio do its basic functionality the same war (the upgrades were only some memory functionalities like save your beloved frequencies and screen messages).
Although all answers are valid, i still feel, that we have failed. We have failed so much. The dream of being a programmer is to build something, bring you money or satisfaction, and you are bored so you build something completely new.13 -
I would have wanted to bring up SICP again, with the great big warning about the evil assignment operator and state and all the troubles that ensue (just think: concurrency).
But in a way, nothing has really come up from this or my attempts to dig deeper into "everything is a file/object" (Unix, smalltalk), neither from formal languages or the Curry-Howard correspondence. - Maybe there's just nothing, no firm bottom ground to discover. Like the physicists going for their world formula, but instead of a grand, beautiful symmetry that explains everything, we face a shattered world of (incompatible) theories, that is ever so more complex and chaotic through our theories applied to it. There may not be a Platonic ideal world of ideas, but rather partial constructs explaining some particular perceptions.
Similarly the one perfect programming language to rule them all, the perfect abstraction, pattern is probably just another prepubertal fantasy to be sunk.
So maybe instead of seeking the perfect epiphany, we should go for something quite different: the nagging, brooding uneasiness that something is wrong there, that there's something to be fixed... that even negative feeling would propel us to search further, not to stay in whatever is touted as the real thing.
Such irritations I found with Pieter Hintjens' writings. For example when he actively engaged in conspiracy theories. And I'm still not sure, if he just went off the cliff or he's even right alluding that these theories are an act of sanity, a self-defence against the hidden evil mights. I just don't know. Anything. -
It is clear to everyone that Windows is a piece of crap in every possible way.
But I don't understand one thing. Unix existed before Windows. It has always been superb.
Why did Microsoft develop a whole bew crappy OS, instead of keeping Xenix(I know it was licensed) or forking a Unix-like os like Apple did with NeXTSTEP?
Imagine a world where every os is unix like. So wonderful.2 -
DevOps With Ruby and Chef on FreeBSD (and Linux)
I am Ops and Dev by heart. I have always automated *nix systems long before any automation framework was invented because I am pretty lazy. Doing stuff more than once manually is just one time too often for me. Imho Ruby is a really elegant language. The same applies for the tools that are built around it. The Chef ecosystem fits into this with its own elegance and stability perfectly because the server is Erlang driven and the rest is Ruby.
Being a Linux and BSD user since the early 90s I have always loved a *nix system for it's concepts and simplicity. One command for exactly one purpose and everything is combineable like letters are combinable to words in my mother language. I have always loved FreeBSD more though. Imho it is even more focused on simplicity. Because it is a really clean approach of system design that envies a base system and keeps 3rd party separated in a clean way for example. It also values classic UNIX philosophies that most Linux distros these days abandon but which saved my life multiple times through better design and execution that also focuses alot more on stability, fault tolerance and ease of use than any Linux I have come across. The hardcore guys should read "Design and Implementation of the FreeBSD Operating System", compare the readings to the Linux way of things and see for themselves.*

My first day of the "pool" in my school ended. Finally, the first day was learning how to properly use Unix systems. The "Moulinette" has to pass and validate the results, but we can't call it when we want. That's like a debugger that pass at fixed hours...

Whenever I rant about JavaScript and it's terrible way of doing things differently and totally illogical in the way real programmers would do things versus webdev-scriptkiddies...
Whenever I laugh about these engineers who can only 'code' in Matlab...
Whenever I hear people consider configuring (of stuff like WordPress or RGB-Keyboard-Lights etc.) as 'programming'...
I wonder, if I'm just like the 'Real Programmers' back in 1983 who truly considered Fortran or Assembly to be much more superior than Pascal and someone who coded in the latter or even used a simple OS like UNIX couldn't get accepted as a programmer.
Found that old article about "Real Programmers".
It's worth a read.

Just consider someone writing modern computer programs without libraries, ifs, for loops and only gotos by hand from top to bottom...
Some day I want to start some modern project everyone else would do in some random modern scripting language and hack it down in assembly just for fun and to tell people, I did it. So I could call myself a Real Programmer too.2
