Shower thoughts: i wondering something silly, for example address 0xf006 points to address 0xf003 which has value of 0x0000 how did it know if it is a 0 or a NULL

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

LoL relatable

29-year veteran here. Began programming professionally in 1990, writing BASIC applications for an 8-bit Apple II+ computer. Learned Pascal, C, Clipper, COBOL. Ironic side-story: back then, my university colleagues and I used to make fun of old COBOL programmers. Fortunately, I never had to actually work with the language, but the knowledge allowed me to qualify for a decent job position, back in '92.

For a while, I worked with an IBM mainframe, using REXX and EXEC2 scripting languages for the VM/SP operating system. Then I began programming for the web, wrote my first dynamic web applications with cgi-bin shell and Perl scripts. Used the little-known IBM Net.Data scripting language. I finally learned PHP and settled with it for many, many years.

I always wanted to be a programmer. As a kid I dreamed of being like Kevin Flynn, of TRON - create world famous videogames and live upstairs my own arcade place! Later on, at some point, I was disappointed, I questioned my skills, I thought I should do more, I let other people's expectations make feel bad. Then I finally realized I actually enjoy a quieter, simpler life. And I made peace with it.

I'm now like the old programmers I used to mock 30 years ago. There's so much shit inside my brain. And everything seems so damn complex these days. Frameworks, package managers, transpilers, layers and more layers of code. I try to keep up. And the more I learn, the more it seems I don't know.

Sometimes I feel tired. Yet, I still enjoy creating things and solving problems with programming. I still have fun learning. And after all these years, I learned to be proud of my work, even if it didn't turn out to be as glamorous as in the movies.

Client asks for redesign to look more like XYZ site.

I deliver a redesign to look more like XYZ site.

Client wants the site to look more like his old site. But different. Gives extensive instructions on how to design his website to his liking.

At some point, I think I'll be owing him money for his design/dev services, not the other way around.

What is it with these people?

Just finished my aMaZinG biLlioNairE aPp. It was easier than I thought

Today was fucking awesome!

I always wanted to do a project in C++ since I've been more of a Java guy for years now.
And today, I finally wrote a full console program in C++! (For windows, it's a .exe)

The purpose of that program is to show if a file has a file lock on it (because of copying for example).

It started as simple as that, but got complicated quickly:
- It needs colors! So I added colors.
- Just a single file? Boring. I need wildcards, so I can put a * for anything in the file name! Jup.
- Just one directory? Boring. I need a recursive directory walk! Got it.
- But wait! There has to be an option to switch between recursive and wildcard/single mode! So I checked if the first argument equals "-r"! Hacky but works.
- Oh uh... that spams a lot now! The purpose was to show locked files, so I need another argument to specify that I only want to see locked files! Damn now it get's hard... I need a Linux-like command line argument parser (this -h and -s "hello" stuff). So I took the opportunity to write one myself! Done.
- Refactoring everything to use my new fancy parser...
- Adding more and more arguments, just because I can:
- "-d" hides "access denied" messages
- "-l" shows only locked files
- "-r" activates recursive directory walk
- "-f" formats everything nicely, basically printf("%-150.150s | %s", filename, locked); a maximum width which get's truncated if too long so everything lines up nicely
- "-h" which of course displays the help page
- "-w file" watches a file, if the file is locked it will refresh every 500ms, if it's still locked nothing happens, if it's unlocked, the program prints "unlocked" in green and exits. And yes, it does have a rotating line (something like this: "-" "\" "|" "/" "-" and so forth...)

That project was just awesome to make. I learn languages fastest if I just do a big project in them, and today, I really learned a lot.

Thank you for reading all this!

There is this thing called the Pulfrich effect (https://youtu.be/Q-v4LsbFc5c a Tom Scott video about this).

Since I have 3 monitors, I decided to write a small C++ program which copies the image from the first monitor to the second and, with 5ms delay, also to the third.
That way I can sit down like 5 meters away and squint a bit to make both copies overlap. This creates a 3D effect for about half of the time of any moving video.
If you watched the video at the top you should know why, if the right image comes later the background has to move as in the video, and vice-versa.

Just some random thing that came to my mind and it's actually awesome!

Oh god, I was like 13 and just found out about RPG Maker 2000. I got a pirated copy from a friend because ive got no internet at that time. I remember, my first project was with a friend of mine and dayum, we were so dumb and unknowing.

Once we wanted to implement a counter of how many fights a player had.
The problem was, we only knew about switches (boolean variables) and so we started to implement boolean variables like these:

hadOneFight
hadTwoFights
hadThreeFight
and so on, as something like a counter.
We took this to 50 before I asked my friend if this is the right way of doing this.

He answered: "thats probably the reason, why games are so big nowadays" (he just installed morrowind at home...)

Then at one day, I reached the point I didnt knew what I should do next in this project, so I looked around at all the other functions we never even tried and I found something called "variables".
Those where the "real" variables like string and int and wow, suddenly the possibilities where endless. I told him about variables at telephone and what we could do now, but that just got him somehow frustrated so he told me, that he wants to leave this programming thing

I started early in my childhood days, nobody had cellphone or internet here, my phone number was 3 digits long and my home country started to recover from 44 years of communism.

My first dev project was probably to copy game from newspaper to Atari 1300XE

Article listing was around 10 pages long and if you made mistake program didn’t run.
It took me a while I can’t remember how long but probably whole day and I was finally able to play it.

I don’t remember what was game about but later on I learned some BASIC from book and was able to color the screen and stuff like that.

I was about 6 years old.

I also remember that Atari computer had tape recorder where you put cassette to load game.
Some more complicated games were loading more then hour and you need to walk very carefully around or your walk can cause error and operation would fail.

Besides that there were national radio auditions about Atari where at the end they played code sound wave so you can record it on your cassette and then play software from radio on your Atari.

I never managed to do it cause I was living near military airport and pilots were practicing landing and starting above my home causing radio signal noise and breaking my software recoding.

I can probably say that highly accelerating plane could cause game loading problem and it’s not a joke.

When she says she wishes she could find a guy like me but I’m a guy like me.

Recently I had to work on a project using PrestaShop. Naturally I looked up the "docs" and found the part where they recommend to write documentation.

Fine until you realize they don't and the documentation website gives generic useless informations...

A v dumb C language question....

Consider this code snippet:

{
while( getchar() != EOF )
printf("a");
while( getchar() != EOF )
printf("b");
}

Is there some way to get inside the second loop? After I input some text, ctrl+D sends in the text stream and loop 1 executes, then the control waits at the test for loop 1 again, pressing ctrl+D again triggers EOF, but it ends up skipping all loops after

”G as in giraffe” really got me lol

LOL that's why I love C!

The function pointer cast for strcmp because qsort expects a compare function with two const void * pointers instead of two const char * pointers, that's just beautiful.

Not to mention the hack to abuse strcmp on a struct - which just works because the first struct member is a string and the rest just gets swapped with memcpy as opaque data.

I guess that wouldn't pass a code review at work. :-)

Ok, bye....

Here’s a poster with a super short description of each one to help you keep track and find some new useful Linux tools.

Which place do y'all go for developer related comics and memes ? Besides devrant ofc.

I actually wanted to use some in a boring article am about to write. Something with a sword and needle context, like people using heavy frameworks when a small snippet of native code could do just fine.

"devRant has changed" "I'm so fed up with this site" "Its a bunch of hate and memes, it was so much better before"

A rebuttal.

devRant is approximately the same as it was when it was just a newborn. Remember the days of semicolon jokes being unironically funny?

Look at the top rants of all time, for fucks sake. #2 ever is:

"A different error message! Finally some progress!"

Posted three years ago. That's the second most upvoted rant in history (Remember, this was a "rant" because the joke/meme category didn't exist back then), it made it's way into the app store screenshots, and was a welcome post.

Now imagine that posted today. It would probably go over okay, in fairness, but it's certainly at risk of any number of pretentious pricks complaining about how this is "devRANT not 4chan" or how they had seen the joke before and it's a shitty repost.

And sure, the repost bullshit is fair. I'm not saying that all the reposts are good content. What I'm saying is devRant has always been full of reposts - they just weren't reposts in the early days. The quality of content is the same.

There's also the common misconception that your posts need to be directly related to tech to post on devRant. This is a myth propagated by 0 IQ heathens that don't read any further than the name of the application. Your posts can be anything that isn't prohibited, like porn, spam, and, importantly, politics (commonly overlooked rule)

"All the memes are just too much". Oh you poor fucking baby, let me pour you a healthy serving of pity juice. First of all, you can turn off the memes category, and while they will still find their way to your feed, the concentration will be much lower and it will once again be bearable for your pitiful, weak little soul. Do you seriously get annoyed that severely by shitty posts that you need to leave the app altogether, or do you just want the attention of being a "cool hipster that hates on xyz"?

"This place is just filled with hate! Why can't you just respect xyz technology, it isn't actually that bad!"

This is probably the most stupid fucking thing you could possibly ejaculate from your fingers into whatever device you are using to type. Welcome to devRant, we hate on shit. That's at our core. No, xyz technology ISN'T actually that bad, you're correct. But we're here to tear it apart because it probably has frustrated us in the past. I fucking hate JS because it was my first language and it confused the shit out of me. JS is a great language. But I still talk shit about it, and that's what we're here to do.

Like seriously, I know a lot of people post stuff they're proud of here, and then they're met with "Would be great if you didn't use xyz tech", and that hurts, but holy shit, this is devRant. If you're sensitive to criticism, or even just straight up being made fun of, don't post shit that you're proud of. You won't have a good time. It's just not what we do here.

Quick interlude before the conclusion, "My girlfriend dumped me after I named a class after her. She felt I treated her like an object." is also on the first page of all-time most popular posts.

In conclusion, devRant has not changed. Reposts have been a nuisance since day 0, and just because reposts look different these days doesn't mean the quality of content has decreased in any manner. The two main sources of your frustration are the volume of low-quality posts (Mind you, not the concentration of them, but the volume of them) and your own prejudices about the platform. You're looking back with rose-tinted glasses.

Here are some tips for a more enjoyable experience:

-Make sure you have the "Hide reposts" setting ENABLED in settings. Any posts marked as repost will be hidden in your feed, pulling down the concentration of low-quality posts.
-Keep to the algo sorting method. Obviously, algo is a bot, and there's still gonna be some shit content in there anyways, but if you're in recent, you are absolutely guaranteed to see low-quality posts. It's unfiltered.
-Keep in mind that what you consider a "quality" post is not what others consider a "quality" post. Just because you don't like memes doesn't mean memes are poor content. There are people here who have never seen the bobby tables comic. And they deserve the same experience we got when discovering dev humor.
-Don't be a prick. And if you cannot help yourself, leave. Ironically, you're making the site worse by complaining about how bad the site is. You can always come back if you aren't a prick anymore. And you can leave permanently if you choose as well.
-Downvote and move on. You're not doing anything but making yourself more aggravated by leaving a shitty comment about how shitty the shitty post is.
-Think critically. Obviously optional, and I know not many people like to use their brain when a phone is suspended between their hands, but if you want a better experience, remember to use your head and not to lose it.

I think I still have a 64MB HDD somewhere on a shelf at my late grandpa's house.

Now they make CPUs with caches of that capacity...

o tempora..

EDIT:
FFS! This CPU cache contains >44 floppy disks! I've never even had that many!!!

Here is another rather big example of how C++ is WAY slower than assembler (picture)

Sure - std::copy is convenient
but asm is just way faster.
This code should be compatible with EVERY x86_64 CPU.

I even do duffs device without having the loop:
the loop happens in the rep opcode which allows for prefetching (meaning that it doesnt destroy the prefetch queue and can even allow for preprocessing).

BTW: for those who commented on my comment porn last time: I made sure to satisfy your cravings ;-)

To those who can't make sense of my command line:

C++ 1m24s
ASM 19s

To those who tell me to call clang with -o<something>:
1) clang removes the call to copy on o3 or o2
2) the result isnt better in o1 (well... one second but that might be due to so many other things, and even if... one second isn't that much)

After over 20 years as a Software Engineer, Architect, and Manager, I want to pass along some unsolicited advice to junior developers either because I grew through it, or I've had to deal with developers who behaved poorly:

1) Your ego will hurt you FAR more than your junior coding skills. Nobody expects you to be the best early in your career, so don't act like you are.

2) Working independently is a must. It's okay to ask questions, but ask sparingly. Remember, mid and senior level guys need to focus just as much as you do, so before interrupting them, exhaust your resources (Google, Stack Overflow, books, etc..)

3) Working code != good code. You are an author. Write your code so that it can be read. Accept criticism that may seem trivial such as renaming a variable or method. If someone is suggesting it, it's because they didn't know what it did without further investigation.

4) Ask for peer reviews and LISTEN to the critique. Even after 20+ years, I send my code to more junior developers and often get good corrections sent back. (remember the ego thing from tip #1?) Even if they have no critiques for me, sometimes they will see a technique I used and learn from that. Peer reviews are win-win-win.

5) When in doubt, do NOT BS your way out. Refer to someone who knows, or offer to get back to them. Often times, persons other than engineers will take what you said as gospel. If that later turns out to be wrong, a bunch of people will have to get involved to clean up the expectations.

6) Slow down in order to speed up. Always start a task by thinking about the very high level use cases, then slowly work through your logic to achieve that. Rushing to complete, even for senior engineers, usually means less-than-ideal code that somebody will have to maintain.

7) Write documentation, always! Even if your company doesn't take documentation seriously, other engineers will remember how well documented your code is, and they will appreciate you for it/think of you next time that sweet job opens up.

8) Good code is important, but good impressions are better. I have code that is the most embarrassing crap ever still in production to this day. People don't think of me as "that shitty developer who wrote that ugly ass code that one time a decade ago," They think of me as "that developer who was fun to work with and busted his ass." Because of that, I've never been unemployed for more than a day. It's critical to have a good network and good references.

9) Don't shy away from the unknown. It's easy to hope somebody else picks up that task that you don't understand, but you wont learn it if they do. The daunting, unknown tasks are the most rewarding to complete (and trust me, other devs will notice.)

10) Learning is up to you. I can't tell you the number of engineers I passed on hiring because their answer to what they know about PHP7 was: "Nothing. I haven't learned it yet because my current company is still using PHP5." This is YOUR craft. It's not up to your employer to keep you relevant in the job market, it's up to YOU. You don't always need to be a pro at the latest and greatest, but at least read the changelog. Stay abreast of current technology, security threats, etc...

These are just a few quick tips from my experience. Others may chime in with theirs, and some may dispute mine. I wish you all fruitful careers!

Take your pick

So i just had an interesting conversation.

View source images in comments

So some background. I used to do a lot of Minecraft development and server configuration. And Minecraft being made of mostly 12-year-olds they really don't pay very well. So I moved on from Minecraft but someone reached out for me to do their configuration for their server. (this was about a month ago) and I quoted them 40/hr because that's what I charge for my web dev work. So he promptly declined and I thought that was that. But tonight he messaged me and found a 5 month old post saying how I was looking to do free development work in order to get experience. And here is how the converstion when.

(His name is "Candy")

Candy:
Lol
Trying to take advantage of me with your bullshit $40/hour claims
Which is outright laughable
https://mc-market.org/threads/...
”I am looking for a network to stay long-term with and help/see it grow into a bigger server. (I would expect pay later down the road if we work together on an ongoing basis)”
—
Quoting your MC-Market post.
What do you have to say for yourself? Trying to take advantage of people?
Going to say something else completely delusional or own up to the fact that you were trying to take advantage of me?
I already knew you were, but now I have the hard evidence.
As I am not a stupid person.
Not only did your friend lie, but you tried to take advantage of me, thinking I was stupid enough to fall for your $40/hour bullshit for basic configuration work. MineSaga charges $30.00 an hour on the high. Don’t even try to do the same shit you did to me to anyone else. It won’t work.

Me:I was interested in doing plugin development and learning so I offered my services for free so I could learn in a more real environment. I no longer do minecraft plugins rather I am a web developer and my rate is $40/hr I am good at configuration which is why i contacted you but I am not going to lower my rate because it is "simpler" work. Just like how you can higher a prostitute to wash your car but it would be cheaper to get the kid from around the block to do it. Also not sure what your end goal is here. I gave you my rate and you didn't agree with it. So you should just move on. Plus this is the minecraft world let me know when you get to the real world so you you can pay in big boy money.

Candy:
So your configuration work for minecraft is $40/h as well?
Lol
Absolutely hilarious.

Me:
did you not read my message?
"I am not going to lower my rate because it is "simpler" work."

Candy:
Who were your most recent clients?

Me:

i'm not going to give you that information

Candy:
Because you know you are lying to me with your crazy rates, and if you aren't, that means you have near to no clients.
Yet another lie.

Me:
keep telling yourself that buddy

Candy:
Lol
Good luck getting any more clients.
rip

Me:
?
I get more clients all the time
They just are not in your realm of your minecraft imagination where you can pay a developer 20$/hr

Candy:
I just strongly disagree with the fact that you are charging $40/hour for configurative work
xD

Me:
Okay
But why even contact me? Did you really think trying to "Call me out" was going to have me lower my rates or something.
Just get over it

Candy:
I haven't called you out and overcharging like that to others in the minecraft realm for a significant gain in money for work that is not worth nearly that amount is absolutely delusional.
I would recommend you stop making up false assumptions

Me: What ever you say

I left it at that. There was some more stuff but it was not that interesting so i left it out
