*Rules For Work*
1. Never give me work in the morning. Always wait until 4:00 and then bring it to me. The challenge of a deadline is refreshing.
2. If it's really a rush job, run in and interrupt me every 10 minutes to inquire how it's going. That helps. Even better, hover behind me, and advise me at every keystroke.
3. Always leave without telling anyone where you're going. It gives me a chance to be creative when someone asks where you are.
4. If my arms are full of papers, boxes, books, or supplies, don't open the door for me. I need to learn how to function as a paraplegic and opening doors with no arms is good training in case I should ever be injured and lose all use of my limbs.
5. If you give me more than one job to do, don't tell me which is priority. I am psychic.
6. Do your best to keep me late. I adore this office and really have nowhere to go or anything to do. I have no life beyond work.
7. If a job I do pleases you, keep it a secret. If that gets out, it could mean a promotion.
8. If you don't like my work, tell everyone. I like my name to be popular in conversations. I was born to be whipped.
9. If you have special instructions for a job, don't write them down. In fact, save them until the job is almost done. No use confusing me with useful information.
10. Never introduce me to the people you're with. I have no right to know anything. In the corporate food chain, I am plankton. When you refer to them later, my shrewd deductions will identify them.
11. Be nice to me only when the job I'm doing for you could really change your life and send you straight to manager's hell.
12. Tell me all your little problems. No one else has any and it's nice to know someone is less fortunate. I especially like the story about having to pay so many taxes on the bonus check you received for being such a good manager.
13. Wait until my yearly review and THEN tell me what my goals SHOULD have been. Give me a mediocre performance rating with a cost of living increase. I'm not here for the money anyway.

My first story in devRant! Was lurking for quite a while and finally felt like sharing something 🙃24 -
FUCK OFF. It's 2 days before a deadline, I'm wearing headphones and clearly focused and you have the fucking audacity to interrupt me because you're fucking bored? Go light yourself on fire you fucking cunt6

I came from a village, we have animals (like a farm), pigs, chicken, sometimes duck and goose. One day I had to work from home, bc had to come back to parents house. Our daily skype meeting was like this:
* discussing very important IT stuff *
* grandma rushes into my room *
me: sorry, but i have a meeting
grandma: i just wan...
me: but i cannot right no...
grandma: just wanted to know if...
me: grandma, I cannot right now, we have a skyp... im talking with colleagues, on the computer
grandma: * quiet voice * okay, i dont want to interrupt, I just want to know - Did you ordered the ducks?
* what I hear in headphones: collegues and boss LOLd sooo hard *
me: ffs, what ducks?
grandma: did your father not give you the guys number?
me: * starting to sweat * what guy? no he didnt, i have no idea what youre talking about
grandma: * disappointed * then who gonna order them...?
me: ...
grandma: * standing next to me, she hears the laughter * whats that?
since then, if im working from home every skype meeting starts with "Tommy, is your grandma there? HAHA!"7 -
Interviewer asked me how to find the best move in Tic Tac Toe game.
We discussed several ideas and ended up playing Tic Tac Toe for nearly 10 minutes.
It turns out HR was keeping an eye and they had to interrupt.12 -
Dev: I’m taking a vacation next week
Manager: Good you need a break! I’ve put together a list of tickets for you to action during vacation since you’ll mostly be free during that time
Dev: Do you know what vacation means?
Manager: Well I work during *my* vacation
Dev: You write non-answers to emails and interrupt devs with status questions that are easily answered by a single glance at the kanban board. Also, you’ve just assigned a month’s worth of storyboard points to me on my week long vacation. We’d get more work done if you didn’t “work” during your vacation.
Manager: Well it all needs to get done! It’s the only way we can catch up and get ahead of schedule.
Dev: Why do you exist again?15 -
It's 3:30AM and I'm working.
If you work at night, no one can interrupt you.
If you sleep during the day, you can't attend any zoom meetings.
Also, at night you can work naked, and drink on the job without any judgement.
All problems solved.10 -

PM: Hey Brod, I know your really busy refactoring to ES6 but I think our Ruby app broke, could you fix it?..
Me: Ask Tom, he's the only one here who knows ruby he wrote the app..
PM: I didn't want to interrupt his Skype call.
Me: he's not on Skype, that's his face, he's taking snapchats.
PM: oh, well I don't want to really interrupt that either.

A quite normal Windows day:
Bios to Windows: "Go now! Get up!"
Windows to Bios: "Always slow with the young circuit boards."
"I've got something weird on screen."
Windows' answer: "Ignore it first."
Hardware assistant to Windows: "The user puts pressure. He wants me to identify this thing. Could be an ISDN card."
Windows: "Well, well."
Unknown ISDN card to all: "Will you please let me in?"
Network card to intruder: "You can't spread out here!"
Windows: "Quiet in the case! Or I'll cut both their support!"
Device Manager: "Offer compromise. The network card is allowed on Mondays, the ISDN card is on Tuesday."
Graphics card to Windows: "My driver retired yesterday. I'm crashing now."
Windows to graphics card: "When will you be back?"
Graphics card: "Well, not at first."
CD-Rom drive to Windows: "uh, I would have a new driver here..."
Windows: "What's ich´n supposed to do with it?!"
Installation software to Windows: "Leave it, I'll mach´ that already."
Windows: "That's nice to hear."
USB connection to interrupt management: "Alarm! Just been penetrated by a scanner cable. Request response."
Interrupt management: "Where are you coming from?"
USB connection: "I was in the computer right from the start. I'm joined by another colleague."
"You're not on my list." - "Say something."
Windows: "Hopefully there won't be another printer."
Graphics card: "The new driver twitches."
Windows: "We'll just have to get the old one out of retirement."
Uninstall program to new driver: "Go away."
Unwanted driver: "Fuck you."
Windows to Norton Utilities: "Kill him and his brood!"
Utilities to driver rests: "Sorry, we have to delete you."
Important system file: "Arrrrrrgghh!"
Windows on blue screen: "Gib´, the Norton Boys are over the top again."
Blue screen to user: "So, that's it for this week."
Excuse me for stealing your time

So many interruptions!
So many distractions!
I just want to fucking finish this refactor. I dont' care about meetings, texts, bloody office game tournaments, lunchtime, gossip, or people trying to be friendly. Just let me fucking work!
If you see me rocking out with my headphones on and working furiously, seriously, just don't fucking interrupt. I'll bite.16 -
Attack is the best defence! I read my emails in the morning and figure out whether there's some action for me. When I go and get my second coffee, I drop by the PM's office and have a short chat with him.
Where I am in the projects, whether there's stuff from other tasks or unexpected actions, how long that might take, whether schedules are still OK, whether I need him to take care of some customer communication, these things. Usually less than 5 minutes.
The kicker is that he mostly doesn't interrupt me because I instead interrupt him - unless he is highly busy, in which case he just says "sorry, later", same as I would do.
It's a win-win because I can schedule the interruptions while he enjoys that he doesn't have to ask around.5 -
>>> print(whoSaid("OlderFriend"))
About 20ish years ago I was working in IT, and it was about around this time where CD-Roms were hitting the stores and becoming the newest craze. However, Microsoft did not write the drivers correctly for this new hardware.
In a nutshell, the driver would be installed and the user would lose the sound to their speaker.
How did this happen? By altering the way the interrupts worked on the computer. At the time there only existed a few unreserved IRQs or Interrupt ReQuests. The installer package would redirect IRQ 5 which is "User Selectable (Sound Cards)" to work with the CD-Rom. This was fine and all unless you wanted to listen to your speakers.
I had come up with a clever hack through rewriting a config file that would be run during bootup. So at the time of boot up IRQ 5 would be dedicated to the sound card, and IRQ7 (which was usually for the Lpt1 Printer) would be dedicated to the CD-Rom. This worked.
And because I was IT at the time, I would get a lot of calls for fixing this problem.
So, as you can imagine, I've gotten **really** good at doing this. I didn't even need to be at a computer to walk someone through the problem.
I receive a call one day, it was a problem with the CD-Rom and sound card. I walk him through the problem and he reboots his computer. I could hear him on the other side jumping with joy when he was able to put in his music CD and hear sound coming from the speakers.
He asks me, how in the hell did you figure this out!? You're a fucking Genius!
And I said, It's not rocket science it's just a computer.
There was a long pause of silence.
Uhhh... Hello? Did I say something wrong?
Sir, I work at NASA I deal with Rocket Science on a daily basis.4 -
Found this on discord.
Could be copypasta but I decided to share it anyway.
"I use Linux as my operating system," I state proudly to the unkempt, bearded man. He swivels around in his desk chair with a devilish gleam in his eyes, ready to mansplain with extreme precision. "Actually", he says with a grin, "Linux is just the kernel. You use GNU+Linux!' I don't miss a beat and reply with a smirk, "I use Alpine, a distro that doesn't include the GNU coreutils, or any other GNU code. It's Linux, but it's not GNU+Linux."
The smile quickly drops from the man's face. His body begins convulsing and he foams at the mouth and drops to the floor with a sickly thud. As he writhes around he screams "I-IT WAS COMPILED WITH GCC! THAT MEANS IT'S STILL GNU!" Coolly, I reply "If windows was compiled with gcc, would that make it GNU?" I interrupt his response with "-and work is being made on the kernel to make it more compiler-agnostic. Even you were correct, you wont be for long."
With a sickly wheeze, the last of the man's life is ejected from his body. He lies on the floor, cold and limp. I've womansplained him to death.14 -
Teacher: Computer settings are stored in the ROM on the motherboard.
Me: *internally* Uhm, yea, sure... and I am the pope
Me: Sorry to interrupt you but how come the BIOS settings get reset when the CMOS battery is pulled out or dies if they are stored in ROM?
Teacher: ....
Me: *internally* yea, that's what I thought, you have no clue what you are even saying - the BIOS is stored in ROM or flash memory while the settings are stored in NVRAM also called CMOS memory...10 -
I have just concluded a post-mortem on one of my servers.
Cause of death: out of memory due to a tiny memory leak in a VPN service triggered by 66 different IPs brute-forcing the creds at the same time. Mostly from China, of course.
Dear bot writers: you made me put aside my spaghetti and write iptables rules. I hate iptables. And I love spaghetti. You should be ashamed of yourself! Did momma not teach you basic OpSec? Don't crash the target and never, ever, interrupt the sysadmin during dinner!6 -
If you are a salesperson, you can just go straight to hell. You're all a bunch of cocksucking twats and I'm amazed you manage to get yourselves dressed each day. You're a no good fucking waste of oxygen and you need to put your fork in a socket the next time you're eating.
I'm working on building a crm and ticket management system for use in the office to handle client passwords. Since I'm building from scratch I wanted to make sure I had properly planned my classes and functions before opening the code editor so I put a message on my door that says "Don't interrupt, thanks" followed by the date so people knew it was a fresh message and not something left from the previous day.
I'm deep in the zone, the psuedo code and logic is flowing, I'm getting classes planned and feeling really productive for an hour or so when suddenly my door flies open and in comes a sales person.
SP: "Hey, do you have any extra phones lying around? Mine's being slow and keeps hanging up on people."
Me: "Do you see the sign on my door right there at eye level which says not to bother me?"
SP: "oh, do you want me to come back later?"
Me: "You've already interrupted me now, let's go see what's going on before I spent an hour setting up a new phone for you." While we are walking across the office I asked him when the last time the phone rebooted.
SP: "idk, Salesperson#2 suggested that as I was headed over here but I figured I'd just ask you."
We get over to his desk and I see he has two phones sitting on his desk. "Where did this one come from?"
SP: "Oh that was on the desk over here but I figured I could use it."
Me: "Well aside from the fact that the phones are assigned to specific people for a reason, you took the time to unhook your phone to set this one up and you didn't think to reboot your phone first. Plug your phone back in."
He plugs the old phone, which is assigned to him, and while booting it does a quick firmware update and boots up fine. He tests a few things and decides it's all better now.
So someone suggested a fix for you and you decided, instead, you would break company IT policy by moving equipment from one station to another without notifying the IT department. You entered a room which had a closed door without knocking, and you disobeyed the sign on the actual door itself which politely requests that you go away. All because you couldn't be bothered to take 2 minutes and reboot your phone, which you had to do anyways.
You completely broke my train of thought and managed to waste 2 hours of effecient workflow because you had an emergency.9 -
As an introvert & junior dev, I'm so frustrated with video conferencing meetings:
1. People interrupt each other and change topics all the time.
2. People disregard the host's agenda.
3. Meetings are starting to be recorded or secretly screenshotted in the very moment I am frowning because my internet connection is getting bad.
4. The meeting chat turns into a side discussion if the host is not addressing things in the chat and setting the rules clearly.
5. There are lots of buttons missing in my company's VC tool that would display my current status to the other participators, e.g. a no "I agree", "I disagree", or "I have something to add". All I have available in my VC tool is a "thumbs up" or "applause" reaction that stays next to me in my picture for very long 10s...
6. Webinars via VC tools are super uninteractive. To make it worse, there is no pizza, no free drinks and also no side conversations and no walking to the station together with the other nerds.
7. There is no way to tell the person speaking that you haven't heard them clearly or you would like them to explain something further in a big group meeting. It's too embarrassing for me to interrupt or let everyone else know in the chat that I haven't got it.
Bottom line: I HATE video conferences without a good facilitator that involve more than 3 people and would like to write my own VC software but I'm already kinda feeling drained because all these chaotic meetings stress me so much :(3 -

Okay, just because I'm the only one under 35, single, and only white/hispanic guy on this team doesn't give you the right to interrupt me mid sentence IN my meeting. No disrespect to the developers from India and this may just be a culture conflict where I am outnumbered in my company but I don't understand the how some of these guys can't just be polite or respect others opinions(this is just from my experience with 90 or so developers from India and I don't believe in blanketing all Indians as this way just these 90 plus I do love the food).
Don't hijack MY meeting and then completely derail where I was going and disregard my solution without listening to the whole thing for an idea that isn't even solution but adds more work for both parties involved. You may have been working here for 5 years, but I worked in the actual department where we're building the new process and solution to a problem I've worked on. I understand the user since I WAS ONCE THAT USER for a good 8 months. And on top of that you can barely code efficient, or complex SQL statements. You're nothing more than fucking script kiddies and this whole IT department is joke. I apologize if the rant isn't really that coherent, I'm not very good at typing rants with my adrenaline running hot.14 -
I fucking hate being the "ask me anything" guy in the office, how am I supposed to code if people interrupt me every 5 minutes?
OH LOOK AT MY HEADPHONES! MAYBE I'M CONCENTRATED AND HAVE SHIT TO DO! I mean there are other 10 devs, why don't you go to them? or maybe try to GOOGLE IT, I HEARD STACK OVERFLOW IS GOOD YOU PIECE OF SHIT!
don't get me wrong, I like to help people but I hate when those bastards come asking questions that could be easily answered if they read the code for 5 fucking minutes.
when I have to look at code that is not mine I try to understand it by myself, even if it's not documented, and I try not to bother anyone unless is really necessary.
But then this sluggish leeches think I know the whole codebase and that can interrupt me whenever they can.7 -
Our web department was deploying a fairly large sales campaign (equivalent to a ‘Black Friday’ for us), and the day before, at 4:00PM, one of the devs emails us and asks “Hey, just a heads up, the main sales page takes almost 30 seconds to load. Any chance you could find out why? Thanks!”
We click the URL they sent, and sure enough, 30 seconds on the dot.
Our department manager almost fell out of his chair (a few ‘F’ bombs were thrown).
DBAs sit next door, so he shouts…
Mgr: ”Hey, did you know the new sales page is taking 30 seconds to open!?”
DBA: “Yea, but it’s not the database. Are you just now hearing about this? They have had performance problems for over week now. Our traces show it’s something on their end.”
Mgr: “-bleep- no!”
Mgr tries to get a hold of anyone …no one is answering the phone..so he leaves to find someone…anyone with authority.
4:15 he comes back..
Mgr: “-beep- All the web managers were in a meeting. I had to interrupt and ask if they knew about the performance problem.”
Me: “Oh crap. I assume they didn’t know or they wouldn’t be in a meeting.”
Mgr: “-bleep- no! No one knew. Apparently the only ones who knew were the 3 developers and the DBA!”
Me: “Uh…what exactly do they want us to do?”
Mgr: “The –bleep- if I know!”
Me: “Are there any load tests we could use for the staging servers? Maybe it’s only the developer servers.”
DBA: “No, just those 3 developers testing. They could reproduce the slowness on staging, so no need for the load tests.”
Mgr: “Oh my –bleep-ing God!”
4:30 ..one of the vice presidents comes into our area…
VP: “So, do we know what the problem is? John tells me you guys are fixing the problem.”
Mgr: “No, we just heard about the problem half hour ago. DBAs said the database side is fine and the traces look like the bottleneck is on web side of things.”
VP: “Hmm, no, John said the problem is the caching. Aren’t you responsible for that?”
Mgr: “Uh…um…yea, but I don’t think anyone knows what the problem is yet.”
VP: “Well, get the caching problem fixed as soon as possible. Our sales numbers this year hinge on the deployment tomorrow.”
- VP leaves -
Me: “I looked at the cache, it’s fine. Their traffic is barely a blip. How much do you want to bet they have a bug or a mistyped url in their javascript? A consistent 30 second load time is suspiciously indicative of a timeout somewhere.”
Mgr: “I was thinking the same thing. I’ll have networking run a trace.”
4:45 Networking run their trace, and sure enough, there was some relative path of ‘something’ pointing to a local resource not on development, it was waiting/timing out after 30 seconds. Fixed the path and page loaded instantaneously. Network admin walks over..
NetworkAdmin: “We had no idea they were having problems. If they told us last week, we could have identified the issue. Did anyone else think 30 second load time was a bit suspicious?”
4:50 VP walks in (“John” is the web team manager)..
VP: “John said the caching issue is fixed. Great job everyone.”
Mgr: “It wasn’t the caching, it was a mistyped resource or something in a javascript file.”
VP: “But the caching is fixed? Right? John said it was caching. Anyway, great job everyone. We’re going to have a great day tomorrow!”
VP leaves
NetworkAdmin: “Ouch…you feel that?”
Me: “Feel what?”
NetworkAdmin: “That bus John just threw us under.”
Mgr: “Yea, but I think John just saved 3 jobs. Remember that.”4 -
A senior developer come to interrupt me.
Senior developer: blah...blah....blah about this concept...... that concept... So, any new things you learn lately that you would like to share?
Me: I am learning back C++
Immediately he stop me and said, "Why did you learn C++? It is obsolete, no one use it anymore"
Me (in my head): But, you just said what I learn. It doesn't matter if its obsolete or not. Infact you are wrong, C++ is not obsolete anytime soon. I was about to share on webassembly.
Senior developer: So, would you like to join me in a short sharing session this afternoon.
Me: No thanks, I am really busy (just want to avoid at any cost)8 -
Man I really hate it when people think that coding doesn't take any concentration and can just interrupt you while you're thinking about how to solve problems
So the other day I was working on how to solve a problem with filtering data with JS, and I had to urgently update one of our pages on our website. I had to update that page according to the content of a Word file, which I didn't check how long it was.
About 15 minutes later everything was ready and published, so I set myself back to my problem.
I get an email from her, "you mixed up things" and she showed up in my office. "There are four pages in this word doc and you copied wrong parts", I was like "ok, I'll fix it". Fixed it two minutes later, went back to code.
Received another email, with another subject, again with another problem. Start getting pissed off for being interrupted for nonsense. Fixed it instantly and put my manager in the email loop so she is aware my other colleague pisses me off.
And again, another direct email "can you fix this?!". I started ignoring her requests because I need some work to be done, and I already lost 2 hours. Got again interrupted by her personal visit to point me which things are wrong, repeating everything twice as I am stupid to her. Man I can't code in peace. I fixed her shit, exactly as she wants and decided to pay my manager a visit to tell her I'm really pissed about being interrupted all the time.
Five minutes before the end of the day, she comes panicking in the office about ANOTHER WORTHLESS issue. Told her it's nothing and went away.
Day is over, thought it was over - a whole afternoon spent correcting her fucking page that gets 10 visits a year.
On the next morning, "there is something wrong with your form, can you check it?!!?" with an attached screenshot. FFFFFFFFUUUUUUUUU STOP ANNOYING ME WITH YOUR FUCKING SHIT CANT WORK ANYMORE. PUT YOUR FUCKING PAGE RIGHT UP YOUR ASS AND FIX IT YOURSELF.
She doesn't have any access to the back end.
Guess I'll have to fix it then...9 -

I did a 3 years study in computer science.
I got an intern that is on her last year of a 5 years study in computer science too.
So we have the same age, just that I have more practical experiences than her and she have more theoretical baggage than me.
We are discussing on the design of what she will do over her internship and while I'm talking about some JSON modelling she interrupt me to say something like "so this tuple is meaning..." talking about a JSON object. I didn't get what she was talking about (I never did python and didn't learn much about mathematical theorems during my study) so I asked her: "What is a tuple?".. She looked at me with dead eyes saying "what!? you don't know this ?!!" Like I was the dumbest man on earth. Fortunately our PM which is also a coding guy was sitting next to us and explained to me that by saying "tuple" she meant a "JSON object" and to her that it IS normal if I do not know what a tuple is, first because of my studies, 2nd because my job is to be an Android Dev and that I do not need to know this to do my job. He added that by the way I'm doing well my job and that if I wasn't there to help her on her code she would never succeed her internship.
I'm glad my PM intervene but fuck those who always think they know everything better than others without questioning themselves before !12 -
Yesterday, after six months of work, a small side project ran to completion, a search engine written in django.
It's a thing of beauty, which took many trials, including discovering utf8 in mysql isn't the full utf8 spec, dealing with files that have wrong date metadata, or even none at all, a new it backup policy that stores backups along side real data.
Nevertheless, it is a pretty complete product. Beaming with pride I began to get myself a drink, and collapsed onto the floor, this caused me to accidentally hibernate my computer, which interrupted the network connection, which in turn caused an OSError exception in one of my threads, which caused a critical part of code not to run, which left a thread suspended, doing nothing.
From the floor I looked at my error and realised my hubris and meditated on my assumptions that in theory nothing should interrupt a specific block of code, but in reality something might, like someone falling over...7 -
The solution for this one isn't nearly as amusing as the journey.
I was working for one of the largest retailers in NA as an architect. Said retailer had over a thousand big box stores, IT maintenance budget of $200M/year. The kind of place that just reeks of waste and mismanagement at every level.
They had installed a system to distribute training and instructional videos to every store, as well as recorded daily broadcasts to all store employees as a way of reducing management time spend with employees in the morning. This system had cost a cool 400M USD, not including labor and upgrades for round 1. Round 2 was another 100M to add a storage buffer to each store because they'd failed to account for the fact that their internet connections at the store and the outbound pipe from the DC wasn't capable of running the public facing e-commerce and streaming all the video data to every store in realtime. Typical massive enterprise clusterfuck.
Then security gets involved. Each device at stores had a different address on a private megawan. The stores didn't generally phone home, home phoned them as an access control measure; stores calling the DC was verboten. This presented an obvious problem for the video system because it needed to pull updates.
The brilliant Infosys resources had a bright idea to solve this problem:
- Treat each device IP as an access key for that device (avg 15 per store per store).
- Verify the request ip, then issue a redirect with ANOTHER ip unique to that device that the firewall would ingress only to the video subnet
- Do it all with the F5
A few months later, the networking team comes back and announces that after months of work and 10s of people years they can't implement the solution because iRules have a size limit and they would need more than 60,000 lines or 15,000 rules to implement it. Sad trombones all around.
Then, a wild DBA appears, steps up to the plate and says he can solve the problem with the power of ORACLE! Few months later he comes back with some absolutely batshit solution that stored the individual octets of an IPV4, multiple nested queries to the same table to emulate subnet masking through some temp table spanning voodoo. Time to complete: 2-4 minutes per request. He too eventually gives up the fight, sort of, in that backhanded way DBAs tend to do everything. I wish I would have paid more attention to that abortion because the rationale and its mechanics were just staggeringly rube goldberg and should have been documented for posterity.
So I catch wind of this sitting in a CAB meeting. I hear them talking about how there's "no way to solve this problem, it's too complex, we're going to need a lot more databases to handle this." I tune in and gather all it really needs to do, since the ingress firewall is handling the origin IP checks, is convert the request IP to video ingress IP, 302 and call it a day.
While they're all grandstanding and pontificating, I fire up visual studio and:
- write a method that encodes the incoming request IP into a single uint32
- write an http module that keeps an in-memory dictionary of uint32,string for the request, response, converts the request ip and 302s the call with blackhole support
- convert all the mappings in the spreadsheet attached to the meetings into a csv, dump to disk
- write a wpf application to allow for easily managing the IP database in the short term
- deploy the solution one of our stage boxes
- add a TODO to eventually move this to a database
All this took about 5 minutes. I interrupt their conversation to ask them to retarget their test to the port I exposed on the stage box. Then watch them stare in stunned silence as the crow grows cold.
According to a friend who still works there, that code is still running in production on a single node to this day. And still running on the same static file database.

I sometimes remember the time when I wrote a Email-inbox-exporter-PHP-script-type of application that collects all the emails from an inbox, "copied" it to a database with the attachements and stuff and moves it to a folder..
I just started at the company for like a couple of months, had no privileges to create mailboxes and such and I didn't want to interrupt our programmer to do this for me, so... I decided.. to save time and resources.. to test run it on our global, live 'support' mailbox.. :D Well.. You might guess what happened.. Apparently I mistyped the name of the move-destination folder (because imap-weird-things) that resulted in a completly empty mailbox and an empty database because the inserts failed due to bad encoding and mime-type issues..
The moment I refreshed my Outlook and noticed that all our mails where gone.. I swear, I can't describe that feeling of fear, cold sweat, intense heartbeat... I just stood up, asked if anyone wanted coffee, and just walked out of the office.. When in the hallway, I heard my collegues ask to one another "do you have any issues with outlook, all my mails are gone?". Everyone was stressing out, the chief was stressing out "what happened?!", nobody knew what happened.. :D
They could partially resolve it via one collegue who hadn't refreshed the mailbox and he could forward all the mails back to our support mailbox..
I dropped the project idea and learned to work with dev environments :D A couple of months later, I accidentially forgot a where condition in my SQL UPDATE statement, but that was the last time I seriously f*cked up.. :D Got to learn the hard way I guess.. Now everything I do runs in dev environments, I test everything before publishing,.. When I look back.. I don't even recognize the (inexperienced) guy I was back then ! :D
Ps. No one still knows what happened that day and they blamed it on server issues :Dundefined learned from my mistakes sorry collegues fucked up live testing fml inexperienced empty mailbox3 -
Recap: https://www.devrant.io/rants/878300
I was out Thursday at the Hospital. I'm what the doctors would call "Ill as fuck"
So, Friday I’m back in the office to the usual: "How was that appointment?"
I know people mean well when they ask this. So, I do the polite thing and tell them it went as well as it could.
Realistically it does't matter how well it went... They haven't cured Crohn's because I showed up to the appointment. They know I'm fucked already.
But, push it down, add it to the future aneurism.
I had to go through the usual resignation meetings with managers:
"We"re fucked now you're going"
"yep"
"we need to get a handle on how fucked"
"already done that for you, here"s a trello board, very fucked."
"we need to put a plan together to drop all the junior devs in the shit with the work you’ve been doing"
"You need about 4 devs, please refer to the previous trello board for your plan"
Meanwhile, me and Morpheus are in constant communication because all of this is like a Shakespearean comedy.
So, I overhear a conversation between a Junior Dev and the Solution Architect.
[SA] took over the project because he knows better than two tried and tested senior devs -_- (fuckwit).
JD: "It took me one and a half days to build it out"
SA: "Yeah, it must have taken me twice as long... It must be a problem with the project, you should just be able to check it out and run it."
JD: "I know, it has to be wrong"
All of this is about Morpheus' work of art, of an Ionic 3 hybrid app.
I fumed quietly at my desk because I've been ordered by the Stazi to be hands off.
Since Morpheus and me were pulled from the project [JD] and [JD2] were dropped into it to get it over the line.
It"s unfortunate and I was clear and honest with my advice to them: I personally would not take over the project because I"d be way out of my depth... Oh, and the App works, so uh, there's no work to do.
They have been constantly at our desks. Asking fuckdiculous questions about how to perform basic tasks. So they can get Morpheus" frigging masterpiece to the user.
It"s like watching that touch up of jesus that got borked by an amateur. Shit I have google, it's like watching this happen: http://ti.me/NnNSAb
[JD] came to me Friday evening.
"I can’t get this to build to iOS or install on [Test Analyst]'s phone."
Me: "No worries brother, where are you stuck right now?"
[JD] describes the first steps with clear indication he hasn't googled his problem.
Life lesson: http://lmgtfy.com/?q=lmgtfy
Que an hour of me showing [JD] how to build an Ion3 project for iOS. Fuck it, your man's in a bind and he"s asked politely for help. I can show him quicker than he can read 3 sets of docos.
I took him through 'ionic cordova build ios', the archive and release processes in XCode 9, then the apk bundling process for droid. Finally we have an MAM so the upload process for that too.
All the while cleaning up his AppIDs, Profiles, deployment attempts.
Damn they were a mess.
I did this with a smile on my face, not because I could say "I told you so"... But. because when any developer asks you how to do something. If you know how to do it, you should always be happy to learn them some new tricks!
Dude's alright, he's been dropped in the shit. Now I know how badly so I'll help him learn things that are useful to his role, but aren't project specific.
As a plausi-senior dev (I'll tell you about that later); it's my job to make sure my team have what they need to go home smiling!
I’m not a hateful fucker, the guy asked me an honest question so I am happy to give him the honest answer.
I took him through it a few times and explained a few best practices. Most were how to do his AppID and ProvProfile set up. Good lad, took it all on board.
However! In his frustration, he pointed the finger at Morpheus' "David" (ref: Michelangelo).
He miraculously morphed into a shiny colourful parrot and fed me SA's line:
"you should just be able to build from a clean clone"
My response was calm and clear:
"You can, it took me 20 minutes on Thursday evening. I was bored and curios, so I wanted to validate Morpheus' work. Here it is on my iOS device and my Android device. It would have taken me 5 if my laptop wasn’t so horrifically out of date."
I validated Morpheus' work so I have evidence, I trust that brilliant bastard.
I just need to be able to prove it's good.
[JD] took this on board.
Maybe listening to two tried and trusted senior devs is better than listening to a headstrong Solution Architect.
When JD left for the weekend I was working a late one (https://www.devrant.io/rants/874765).
His sign off was beautiful.
"I think I can happily admit defeat on this one, it can wait until Monday."
To which I replied: "no worries brother, if you need a hand give me a shout."
Rule 1: Don't be a cunt.
Rule 2: If someone needs help and you can give it: Give it!
Rule 3: Don't interrupt James' cigarette time.

Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).46 -
You wanted to hear more about my "glorious" teacher. I deliver. So get a cup of tea, take a seat and prepare for insanity.
As I already told in a comment my programming teacher is one special snowflake who lives in his personal bubble. We have final exams in less than a month and he spents at least half a lesson talking about vanishing bees and missing plants from his garden. Other topics he likes to talk about (and tries to turn every freaking conversation into at least one of these):
1. Other students and their stupidity
2. Diesel scandal
3. His sick wife
4. "Why does noone read newspapers anymore?"
5. Why he can't teach Java but really really really wants to and everyone hates him and forces him to do C#.
Even if I try to interrupt him he'll go on until he thinks we gained some "common knowledge" - this is how he justifies these topics.
Everytime he introduced us to a new command he compared it to Java and sometimes he even falsely corrects code because he confuses them.
We are only 6 people including me (another story for another time) and he is not able to help everyone during a 90min lesson. He normally sticks with one person for at least one hour and just talks to them or even do their tasks. This is really annoying if you have a simple question. He won't answer you until he's finished whatever he's doing.
Most of the time he doesn't seem to understand what he's talking about/trying to teach us. He's muttering statements from our textbook to himself switching halfway through to another sentence while drawing not decipherable shit on the blackboard.
Another gem are his "guidelines" for classtests. We are allowed to use any command we know. Except the ones we learned not in class. And the ones he doesn't like. And the ones he doesn't want to exist. And of course not the ones which make you're life easier. So basically we are bound to use his favourite commands or we won't get a good grade. Example: use an array. List is not allowed. Never.
He has some weird fetish with arrays.
I once presented him perfectly fine code I wrote in my freetime and asked what some warnings meant. (Was because of different Visual studio versions as I learned later.) He scolded me for using things he didn't taught us yet and ranted about how I'm pressuring him into rushing these things now - I never wanted to show this to my classmates nor was this anything else than a project for fun and learning something new. (FYI the "new stuff" where classes and objects because i was tired of kilometers of spaghetti code). His rant went on a good 20minutes and - obviously - he didn't answer my question. I asked my fiance that evening and he explained it to me.
This should it be for this time. I'm sure I have more stories to tell for another time!
Thank you for reading. ^^5 -
Remembering a university lecture
Prof: "What are some other downsides of using polling instead of interrupts?"
Student: "The process has to wait until it gets polled."
Prof: "Exactly. When you click Ctrl+W, you want that tab to be closed immediately. You don't want the system to wait a few seconds for those keys to get polled and risk your mom looking at that tab."6 -

Today I had the pleasure to introduce to my Professor (who teaches Python) that you could cause a keyboard interrupt typing Ctrl-c. Her logic was that "Ctrl-c is for Copy" and the only way to end a infinite Loop in the shell is to, "X out the Window." She also clearly has never dealt with linux or terminals.13

Another project with legacy code got just dusted off at work. Shits fucked beyond recognition! We got:
- Rando variable names that mean nothing
- Timers running with a cycle time of 2.5ms if you start them with the multiplier 1.
- An Interrupt routine thats 300 lines long.
- Another interrupt thats starting an ADC conversion and waiting for it to complete before returning.
- For loops that start with one and subtract one from the iterator in the loop
- Every value that would normally be expressed as a regular number is written down in Hex. Eg: if(val==0x05)
- State machine built without writing down which state is which. Its just a number. (In hex obviously!)
- All running on a Microcontroller you cant debug on.
- Using a compiler no one has ever heard of before.
- Weird ass Port manipulations
- 15 different .hex and .elf files with no clue whats in them.
- No version control
- We tried explaining the code to a monkey and it hanged itself.12 -
So this was going to be a comment but damn!!!!
Windows is seriously about making life harder for power users now, every fucking update lately is moving more easy to change things and fucking hiding them inside hidden menus or stupid links that don’t make sense. I mean fuck I just want to turn on dual screen with my laptop (because for some bizarre reason, just showing the desktop on the plugged in monitor is so hard to do automatically, especially since I just plugged a hdmi cable in) and the fucker was gone with nothing but a “detect screens” button before it would use an external screen.
Fuck I’m so close to pulling the plug on windows, but Linux just doesn’t sell me for daily use (yet... it’s getting there though)
The fucking forced updates (yes I consider a random bsod due to a system interrupt, then as it reboots magically has updates awaiting... a forced update) are starting to get to me, the fucking thing half crashing and not responding due to a network transfer of files (the fucker was 5GB)
If it wasn’t for my gaming needs and someone can show me a very good alternative to MS Visio (I haven’t really found one yet) then I would swap over and just adjust to the not so great (imo) desktop environments.5 -

So recently I did a lot of research into the internals of Computers and CPUs.
And i'd like to share a result of mine.
First of all, take some time to look at the code down below. You see two assembler codes and two command lines.
The Assembler code is designed to test how the instructions "enter" and "leave" compare to manually doing what they are shortened to.
Enter and leave create a new Stackframe: this means, that they create a new temporary stack. The stack is where local variables are put to by the compiler. On the right side, you can see how I create my own stack by using
push rbp
mov rbp, rsp
sub rsp, 0
(I won't get into details behind why that works).
Okay. Why is this even relevant?
Well: there is the assumption that enter and leave are very slow. This is due to raw numbers:
In some paper I saw ( I couldn't find the link, i'm sorry), enter was said to use up 12 CPU cycles, while the manual stacking would require 3 (push + mov + sub => 1 + 1 + 1).
When I compile an empty function, I get pretty much what you'd expect just from the raw numbers of CPU cycles.
HOWEVER, then I add the dummy code in the middle:
mov eax, 123
add eax, 123543
mov ebx, 234
div ebx
and magically - both sides have the same result.
Why????
For one thing, there is CPU prefetching. This is the CPU loading in ram before its done executing the current instruction (this is how anti-debugger code works, btw. Might make another rant on that). Then there is the fact that the CPU usually starts work on the next instruction while the current instruction is processing IFF the register currently involved isnt involved in the next instruction (that would cause a lot of synchronisation problems). Now notice, that the CPU can't do any of that when manually entering and leaving. It can only start doing the mov eax, 1234 while performing the sub rsp, 0.
----------------
NOW: notice that the code on the right didn't take any precautions like making sure that the stack is big enough. If you sub too much stack at once, the stack will be exhausted, thats what we call a stack overflow. enter implements checks for that, and emits an interrupt if there is a SO (take this with a grain of salt, I couldn't find a resource backing this up). There are another type of checks I don't fully get (stack level checks) so I'd rather not make a fool of myself by writing about them.
Because of all those reasons I think that compilers should start using enter and leave again.

This post showed very well that bare numbers can often mislead.21 -
I miss old times rants...So i guess, here it goes mine:
Tomorrow is the day of the first demo to our client of a "forward-looking project" which is totally fucked up, because our "Technical Quality Assurance" - basically a developer from the '90-s, who gained the position by "he is a good guy from my last company where we worked together on sum old legacy project...".
He fucked up our marvellous, loose coupling, publish/subscribe microservice architecture, which was meant to replace an old, un-maintainable enormous monolitch app. Basically we have to replace some old-ass db stored functions.
Everyone was on our side, even the sysadmins were on our side, and he just walked in the conversation, and said: No, i don't like it, 'cause it's not clear how it would even work... Make it an RPC without loose coupling with the good-old common lib pattern, which made it now (it's the 4th 2 week/sprint, and it is a dependency hell). I could go on day and night about his "awesome ideas", and all the lovely e-mails and pull request comments... But back to business
So tomorrow is the demo. The client side project manager accidentally invited EVERYONE to this, even fucking CIO, legal department, all the designers... so yeah... pretty nice couple of swallowed company...
Today was a day, when my lead colleague just simply stayed home, to be more productive, our companys project manager had to work on other prjects, and can't help, and all the 3 other prject members were thinking it is important to interrupt me frequently...
I have to install our projects which is not even had a heart beat... not even on developer machines. Ok it is not a reeeeaaally big thing, but it is 6 MS from which 2 not even building because of tight coupling fucktard bitch..., But ok, i mean, i do my best, and make it work for the first time ever... I worked like 10 ours, just on the first fucking app to build, and deploy, run on the server, connect to db and rabbit mq... 10 FUCKING HOURS!!! (sorry, i mean) and it all was about 1, i mean ONE FUCKING LINE!
Let me explain: spring boot amqp with SSL was never tested before this time. I searched everything i could tought about, what could cause "Connection reset"... Yeah... not so helpful error message... I even have to "hack" into the demo server to test the keystore-truststore at localhost... and all the fucking configs, user names, urls, everything was correct... But one fucking line was missing...
EXCEPT ONE FUCKING LINE:
spring.rabbitmq.ssl.enabled=false # Whether to enable SSL support.
This little bitch took me 6 hours to figure out...so please guys, learn from my fault and check the spring boot appendix for default application properties, if everything is correct, but it is not working...
And of course, if you want SSL then ENABLE it...
spring.rabbitmq.ssl.enabled=true

So... I've got a confession to make.
I'm no longer a Dev. After the disaster that was my last commercial gig, I went and got a sec Ops role... And I love it. It's just technical problem solving and explaining all the way.
Don't get me wrong, I still love to code. But that's exactly the thing. As a commercial developer employed by corporations, I spent close to 80 % of my time not coding, but in useless meetings, or trying to figure out just what my colleagues thought was "common sense", reverse engineering their work and documenting how to get it running, etc. Basically, fixing shit for braindead academics with next to no real world experience.
Now, when I code, I get to do it on my own terms, with my own stack and as much comments and docs as I want to have. I own my time, and the only ones that are allowed to interrupt me is the local fire department.
I can do what I'm fucking passionate about and leave the rest for the useless people.4 -
When you want to get stuck into coding, but you just KNOW someone is waiting to interrupt you. It could be 5 minutes from now, 10 minutes or 45. You don't know. You can hear their breathing and their footsteps, just waiting for you to get deep into your code.
So you sit there looking for pointless short term crap to do until you know it's clear to start work.2 -
Been working for a while with some terrible code with no documentation that I just inherited from a previous employee
Topic: multi-threaded program in Python
Goal: kill both parent and children with keyboard interrupt
Intuitive idea: check in children processes if parent still alive
Implemented idea:
- parent creates socket connection
- keyboard interrupt kills parent and thus the socket connection as well
- children receive some specific socket error from the loss of connection
- children catch the exception and are killed
In Python 2, of course
I, too, like to inflict pain on myself for fun7 -
What a new years start..
"Kernel memory leaking Intel processor design flaw forces Linux, Windows redesign"
"Crucially, these updates to both Linux and Windows will incur a performance hit on Intel products. The effects are still being benchmarked, however we're looking at a ballpark figure of five to 30 per cent slow down"
"It is understood the bug is present in modern Intel processors produced in the past decade. It allows normal user programs – from database applications to JavaScript in web browsers – to discern to some extent the layout or contents of protected kernel memory areas."
"The fix is to separate the kernel's memory completely from user processes using what's called Kernel Page Table Isolation, or KPTI. At one point, Forcefully Unmap Complete Kernel With Interrupt Trampolines, aka FUCKWIT, was mulled by the Linux kernel team, giving you an idea of how annoying this has been for the developers."
>How can this security hole be abused?
"At worst, the hole could be abused by programs and logged-in users to read the contents of the kernel's memory."

I have a couple of thoughts about social justice controversies from these last years.
I think it's hard to have a good opinion about these events for several reasons.
One reason is that finding good information in 2019 is very hard.
Revenue based sites (thus unneutral) dominate the search results. You search about something and you find thousands of sites basically saying the same thing (because they copy each other).
That's why the existence of a free and open search engine is so important, so it's easier to find neutral hence good information on which to base your opinions, but they are prohibitively big for small groups to build.
Another reason is that controversies generate shock and shock curtails rational thinking. Maybe that's how the primitive brain works?
I'm not much of a scholar to feel confident to say that, but it's so recurrent that it's not too much of a wild guess.
When a controversy happens, a natural reaction is to pick a side. This means that:
a) we assume that there are only 2 sides, and
b) we must pick one of them
So, maybe the human is a bad politician by nature?
Also, because of the shock controversies generate, peaceful dialogue is very rare.
I have yet to see peaceful dialogue online about what patriarchy means to feminists and a lot of other terms they use.
I don't care much about feminists that vandalize or interrupt talks (yelling over someone else is abuse in my opinion).
But for the rest of them, I think discussing their ideas would be good.
I say this because most feminist discourse I see online is not open. Or maybe there are such instances but the web is so big that it's hard to find such instances.
I think some part of the modern feminist doctrine is bullshit, and some part is true.
I for one hate when some men I know in life expect their wives to be their cooks+cleaners (unless they want to do that, willingly). Personally, I'd encourage my wife to get a job (rightfully so, not just to meet some minority quota in some company).
I don't mind either calling a trans person the pronoun she wants.
But other ideas are awful, like the idea that meritocracy is patriarchy, so you need to force minorities to meet a proportionate quota. That's terrible reasoning.
Or the excessive self appreciation culture, like saying to yourself "you are pretty, you are beautiful, you are perfect". I think that grows arrogance and black-or-white thinking.
And some other ideas as well.
I guess the same you can say about any doctrine with different degrees. Some part is bullshit, some part isn't.
Some right wing people hate everyone who isn't white by default, but some want to have more immigration control.
I sure don't like the experiment of separating children from families like the current us govt did, but I wouldn't be happy either to know that by '99 50% of gangs members in the us were hispanic.
With this, I'm not going to say "embrace everyone's ideas" like an idiot. I hate when people do that. It's a stupid and weak reaction to radicalism.
In fact I think the way you fight radicalism and bad doctrines is that you listen to them and maintain good dialogue and counterargue in a respectful but insightful manner.
Making snide remarks, insulting or trolling won't change anyone's mind. That is just throwing fire to the fire.
In fact, when someone gets harassed because of something they believe in, usually it results in even more adherence to their beliefs, because of the usual assumption that success or goodness is full of strife.
So by telling a "sjw" or kkk member that they are idiots over twitter, you are in fact making them stronger believers in their doctrine.
Think of Daryl Davis, a black guy that made 200 members leave the kkk. How? He didn't tell them they were assholes, he somehow made friends with them.
I feel bad now because I've been trolling new devrant users a lot because of how they worsen the quality of the site, but maybe I should tell them that they are ruining the site somehow in a nice way and maybe they'll listen? I dunno...23 -
Rant:
I am at work, some one says to me this system we are working on is multi threaded. I tell the no its not multi threaded and in this context. Things cannot happen concurrently. Its a single core arm 7tdmi. Arguments ensue abot the difference between multithread multitasking an multiprocessing. I proceed to explain this is a multitasking interrupt driven system. With no context switching or memory segmentation so one heap for all tasks cause thats how we have it configured and there is only one core. So there is no way the error he just described could possibly happen. Then he tells me im wrong but refuses to even look at the processor manual and rejects the Wikipedia entry for multithreading. So I plan on calling off so i can just have the next two weeks off while he trys to figure out why two things ar happening at once on this system. He deserves all the frustration that is to follow.1 -
There are a lot... I am going to pick the interview dialogue (incl. test) with the government.
Following situation:
-5 recruiters
-3 candidates (including me) who have all passed an online test that did last for 3 hours
The online test was for the government to see how every candidate is good at math, English, situation adaptation, historical questions, a little bit of techy questions like "What does fps stand for?" and basic questions like that.
Even tho I did apply for a job as a software developer, there was not a single fucking question about programming. I shit you not. Anyways...
After everyone did introduce themselves. I was given the following question by one of the recruiters:"How do you think will the regular work look like to you, if you were to schedule it? We will be starting with you, <myName>"
Me:"Since this is hopefully going to be my first job in software development, I can only assume it for now. Based on my knowledge about this specific topic that I have made by reading other software developers' work experiences in form of textual content, I guess that I am going to do this [...] and that [...]. Oh and after this comes the planning phase (I had mentioned the sprints and agile "frameworks") and meetings of how the projects are doing so far.
After this comes the phase of sitting down and getting to work on the project I am assigned to.
At the end comes the "see you tomorrow, xyz" phase and everyone leaves."
Somebody else from the 5 recruiters:"I am sorry to interrupt you right here, but we are not offering you a dev job. It rather is a mixture of dev and sysadmin. You will be working most of the time fixing someone's problem with their PC and not sitting in a dark and empty corner of a warm room."
This was such a disrespect that I could not give an answer to. I was deeply shocked. Developers need more respect. Most of the fucking things you use, are created by developers, you asshole.
"We will be very happy, if you can call us by tomorrow to let us now if you are still interested."
Me does not even bother anymore and blacklists that government as a "trust me. You do not want to work there" type of job offering place.
Since I did not sign any NDA. It is the government of Germany.
PS: I did apply for a *dev* job. But somehow they did decide to create a new job and assign me to it. That is not professional.5 -
Not Speaking The Same Programming Language
(It is the mid 80s, and I have a coworker come to me with two full pages of computer programming source code.)
Coworker: “Hey, can you help me with this? This function is not working right.”
Me: “Sure. What’s it do?”
Coworker: “Well, on the first line I copy…” *drones on for a few seconds about stuff I can clearly read*
Me: “Wait! Let me interrupt for a moment. I can read the code. In 20 words or less, what does this do?“
Coworker: *long pause that tells me he’s having trouble seeing the forest for the trees* “It, um, converts a date that’s a string to three integers: month, day, and year.”
Me: “Ah! Excellent. And by the time you get the string, has it been sanitized? You know, guaranteed to be pairs of digits with a slash in-between, not blanks or words or other garbage?”
Coworker: “Oh, yeah, all the user input is cleaned up.”
Me: “Okay, good.”
(I scribble “sscanf(text, “%02d/%02d/%02d”, &month, &day, &year);” in a blank spot on the page.)
Me: “Throw out everything and replace it with that.”
Coworker: “You’re kidding.”
Me: “Not at all. Use that. It’ll work. Trust me.”
Coworker: *not sure* “Well, okay.”
(Half an hour later he’s back and looking a bit sheepish.)
Coworker: “That worked. Thanks.”
Me: “No problem.”
(It’s been 30 years. Unfortunately, the new generation of programmers is in the same spot.)

So I recently returned from university and was catching up with people. Then this guy(childhood friend) who is in EE was "asking" me about how my academics were going. So I was describing my cs classes to him until he suddenly interrupted me saying he knows "how algorithms work" and also that IT == CS. I tried my best to explain to him that it is not the same thing, but his ego just couldn't allow me to talk. He continued on forcefully about how he did a project in java that used SQL and blahblahblah. After he was done exhibiting himself, he asked me what languages do you know(LOL)? When I tried to explain to him that cs is not about learning languages, the guy proceeded to interrupt me again and tell me how his curriculum is hard so as to imply that mine is shit. Finally, this human waste told me to "open java" so that he could code, I opened up my terminal, which he responded to by asking me "What is that?"2

Dont become a dev if you:
- Cant sit in the office for 8-10 hours a day
- Dont know how to google information/ errors, instead you interrupt your teammates with stupid questions every 5 minutes
- Are a perfectionist and don't like constant change.
- Are neurotic and give up easily. If you get triggered about broken or messy things to the point where it ruins your day to you and everyone else around you. You need to separate your work from your life.
- Don't have good communication skills. Worst I saw was a guy who speaks with a stutter(nobody understands him) and also writes very poorly (nobody understands his emails). Also he gets very angry when you ask additional questions to clarify what he said. How can you work with someone like that?
- Are very sensitive to critique. I prefer someone telling me that my code is shit and telling me why, instead of feeding me delusions and false validation.
- Dont know how to balance working in team and working solo. Nobody likes lone wolfs who are arrogant and not in sync with the team. But also nobody likes to drag teammates who cant think for themselves and even after years of spent in the field are required constant spoonfeeding because they are unable to google and teach themselves with trial and error.14 -
My colleague can be so fucking annoying I’m close to snapping. It’s morning, I just got it, didn’t have any coffee yet and he asks me “what did you do while I was gone?” (He was away sick a few days). So I start explaining to him the code changes we did and he takes it as an opportunity to interrupt me and ask more questions during my explanation. Mostly because he thinks it’s amusing. I continue explaining not giving in to his shit and he continues interrupting me and tries to make other team members laugh at his stupid face. No one does. I finally tell him to shut up and listen and he does.
It’s like having a kid run around, focusing on every sound other than what is important and trying to be funny when all that’s happening is everyone thinking he’s and asshole that should shut the fuck up. ARGH!!! So annoying.6 -
When you're deep in thought about a complex problem with your headphones in, and someone comes and stands right in front of you, stares at you and loudly says, "You look like your concentrating really hard!" Causing your train of thought to go "POOF".1

The good: use the hardware watchdog in your application control flow.
The bad: don't use a watchdog.
The ugly: trigger the watchdog from a fucking timer interrupt.3 -
Incident of my colleague, who is really hard-working but ain't so smart strategically.
So this morning the entire team connected to discuss the status or criticalll points.
When my colleagues turn came, she delivered a monologue for 15 minutes straight and was still going strong.
(Fucking hell, I couldn't stop laughing while typing this).
My TPM had to interrupt her, and the way he did is even funnier, to discuss few points.
I was the only one on video and I just couldn't resist laughing at the entire situation.
How the fuck can someone talk non-stop for 15 minutes without being breathless and still can go for another round.
Hahahaha it was hilarious.3 -
I'm sure every tech can relate when I say: "Do not! Interrupt! My weekend! With fucking! Tech issues! Thank you!".
-
I work on many projects at work. There's divisions of teams and each team typically has one project. Each one of those projects have weekly Sprint meetings.
That's great! For the team. That means each team has one meeting a week so it's not too disruptive for those individuals.
Me on the other hand? I've got my hand in all the buckets. I'm on every team. I'm the only person on every team. This means I get to go to every meeting.
Let me rephrase that:
This means I -have- to go to every. Single. Meeting.
Which means I have a meeting every. Single. Day. Even if I didn't touch that project that week.
It is literally THE biggest waste of time. I sit there in a 1-2 hour long meeting saying absolutely nothing, not even being spoken to. I could be working on other projects.
And these meetings normally interrupt something I'm working on. Conveniently in the middle of me being in my zone. It makes me completely un-motivated to work for the hour before the meeting because why bother if I'm just going to get interrupted? And then it takes an hour to get back into everything after the meeting because everyone is fooling around or complaining about the meeting.
So that's three hours of my 8 hour work day completely wasted.3 -
Going on vacation for a couple of days next week. So, apparently, the people scheduling the on-call rotation think it's a great idea to assign me on-call duty next week.
ME: ...you know I'm going on vacation, right?
THEM: Oh don't worry, nothing ever happens, and 95% of the time it's just this easy stuff that can be dealt with quickly.
ME (internally): ...I was taking this vacation time to get *away* from having to think about work. Now I'm going to have to keep this in the back of my mind the entire time I'm away, checking for alerts, and potentially interrupt my flow to deal with work, defeating the point of why I'm taking the down time.
Fuck this. If I'd known earlier I'd have tried to get the time rescheduled, but of course this happens on the weekend, the day before.4 -
Anyone have success dealing with nondevs and explaining the “zone” and to not interrupt if I’m programming and would like to share their techniques? I’m the only developer in the company I work for and all my coworkers/bosses don’t get it and even give me grief about using headphones in the office. I’ve actually gone into vacant offices off the open floor plan to try and program uninterrupted, but I don’t know how long I can keep that up without catching flak.3

[tl;dr at the bottom]
(Project Team Group Chat)
dev: @Desing team, i have a question, there's a required field missing in you design, can i go to your desktop to get an quick answer/explanation about that?
design team:....
dev: hello..?
PM: [writes a huge text to tell me that i can not interrupt them even if its a blocker and that we (dev team) shoul write them down and tell them only once a day in the scrum meeting]
dev: uuumm ok
-next day-
dev: so about that field, why did you...
Client: WHAT? There's a problem with the design!? oh boy, lets re-check every view right now with the whole team!
(it took like 2 hours, the field was missing just because they forgot that feature)
PM: okay, @DesingTeam, answer any questions from developers when they ask you...
tl;dr
we spent almost two hours with the client just because desing team didn't want to answer me a little question -
Spent almost two days debugging the hell out of an interrupt handler only to find out that my reference code (official example from the vendor) has some wrong function calls damn it.3

So happy about being about to convince management that we needed a large refactor, due to requirements change, and since the code architecture from the beginning had boundaries built before knowing all the requirements...
pulled the shame on us, this is a learning lesson card.. blah blah blah
Also explained we need to implement an RTOS, and make the system event driven... which then a stupid programmer said you mean interrupt driven ... and management lost their minds... ( bad memories of poorly executed interrupts in the past).... had to bring everyone back down to earth.. explained yes it’s interrupt driven, but interrupt driven properly unlike in the past (prior to me)... the fuck didn’t properly prioritize the interrupts and did WAYYY too much in the interrupts.
Explained we will be implementing interrupts along side DMA, and literally no message could be lost in normal execution.. and explained polling the old way along side no RTOS, Wastes power, CPU resources and throws timing off.
Same fucker spoke up and said how the fuck You supposed to do timing, all the timing will be further off... I said wrong, in this system .. unlike yours, this is discreet timing potential and accurate as fuck... unlike your round robin while loop of death.
Anyway they gave me 3 weeks.. and the system out performs, and is more power efficient than the older model.
The interrupting developer, now gives me way more respect...4 -
Quick and probably duplicate.
One fucking more time someone comes to me and interrupts me, I swear if it's not important, or chitchat, or something easly googlable, or something you could ask literally anyone else or something that isn't even my shit to handle, I will give the unlucky bastard 30 minute lesson to not fucking interrupt me when Im trying to focus first half of fucking day to do one fucking thing.
What the fuck.
What, should I print big fucking A2 formated poster and stick next to my workstation "If you came here to interrupt me, think if you really need to"?
E:
And no, I dont know where the fuck is your excel file.
And no, I dont give a shit when Im coding that there is cake avail for workers today.
And no, for fucks sakes I dont have time for chitchat, I have deadline on me once again and Im doing something I dont have much expirience in so please leave me fucking alone.7 -
I switched my job a few months ago.
And now instead of having daily rants in our team lead's channel on slack on how I wish to inflict physical harm on one of my interns (and I'm talking interns that would just interrupt a daily to make their breakfast), and having something to bitch about because our method of version control was using the IDE's history.
And that I came on here to make another post about the times that I brought up that we should address our technical debt, and only being met with "we don't have technical debt" by our CTO.
I now have a good dev environment, with also a lot more trust given to the employees, where I actually don't have much to complain, and 0 reason to really post rants about my work here :D
(and the previous company I worked at got sold and merged with another, so I jumped that ship in time :P) -
git add . && git commit -m "Because we're constantly interrupted and because we are not given enough time to do things properly, I need to check in and out of branches all the time (because separate envs are actually separate branches now) and have to interrupt what I'm doing.

I've thought of the perfect analogy for people who constantly interrupt us while we are coding.
It's like you're a mechanic and you are working on a complex engine. You're focused on what you're doing, your hands are filthy, and you're just about to fit the part in that you've been trying to fit in for the past hour.
Someone comes along and asks you to help them open a pickle jar in the middle of your work. So you have to stop what you're doing, wash your hands, and then help them open the jar. By the time you're done your focus has completely shifted, you lost all momentum, and your progress comes to a complete halt.
This is what it's like for us when you come into our office or call us to ask us a question that isn't important or urgent whatsoever. It's especially frustrating when it's the same question that has already been asked 100 times. -
GoLive for this big feature is set for Thursday. So the customer approaches me and asks can our team do it. Sure it can be done if everything goes perfectly, but... This means that the feature won't be tested, everything won't probably go perfectly (which it didn't because of customer selected third party api surprise nondocumented features (bugs)) and Thursday release is almost as dumb fucking idea as Friday release. I said it more nicely and I got:
"I don't agree with you"
from a person who has 0 understanding of what is going on and whose boss pays me to tell them what it needs in order to work and prosper.
And we had this fucking conversation three times. So basically he interrupted my coding that directly impacts the schedule in order to debate how fast things can be done. Don't these people understand that everytime you interrupt a software engineer the deadline is pushed by the same amount of time you waste of mine + 30minutes of refocus time to get back into the thing you were doing.
Best part was that the deadline was this magic date the guy pulled out of his ass without consulting the developer team and nobody really cared about the deadline =D

The joy of having to interrupt your current task to go to a hairdresser appointment...
Kinda feels like giving up playing just to go to do your taxes1 -

Windows 10 update rant:
Didn't even just force the update on me, also broke one of my drivers permanently or something like that. 100% CPU on system interrupt, can't run anything, even task manager is dead. Have to reinstall. Lucky I mainly use Linux and that's fine. Just wanted to play some Doom ffs.
Really pisses me off. Idea for Doom mod: swarm mode with windows updates coming from all directions, only weapon is chainsaw and you could charge up for berserk by doing glory kills.2 -
One thing that i found in common among most of rants was devs getting annoyed by people who interrupt them while coding, obviously it's because we love what we do while in most jobs they wish for someone interrupting them so they can stop working for a while

fuck.. FUCK FUCK FUCK!!!
I'mma fakin EXPLODE!
It was supposed to be a week, maybe two weeks long gig MAX. Now I'm on my 3rd (or 4th) week and still got plenty on my plate. I'm freaking STRESSED. Yelling at people for no reason, just because they interrupt my train of thought, raise a hand, walk by, breathe, stay quiet or simply are.
FUCK!
Pressure from all the fronts, and no time to rest. Sleeping 3-5 hours, falling asleep with this nonsense and breaking the day with it too.
And now I'm fucking FINALLY CLOSE, I can see the light at the end of the tunne<<<<<TTTOOOOOOOOOOOOOTTTTT>>>>>>>
All that was left was to finish up configuring a firewall and set up alerting. I got storage sorted out, customized a CSI provider to make it work across the cluster, raised, idk, a gazillion issues in GH in various repositories I depend on, practically debugged their issues and reported them.
Today I'm on firewall. Liason with the client is pressured by the client bcz I'm already overdue. He propagates that pressure on to me. I have work. I have family, I have this side gig. I have people nagging me to rest. I have other commitments (you know.. eating (I practically finish my meal in under 3 minutes; incl. the 2min in the µ-wave), shitting (I plan it ahead so I could google issues on my phone while there), etc.)
A fucking firewall was left... I configured it as it should be, and... the cluster stopped...clustering. inter-node comms stopped. `lsof` shows that for some reason nodes are accessing LAN IPs through their WAN NIC (go figure!!!) -- that's why they don't work!!
Sooo.. my colleagues suggest me to make it faster/quicker and more secure -- disable public IPs and use a private LB. I spent this whole day trying to implement it. I set up bastion hosts, managed to hack private SSH key into them upon setup, FINALLY managed to make ssh work and the user_data script to trigger, only to find out that...

... there's no nat.
THERE"S NO FUCKING NAT!!!
HOW CAN THERE BE NO NAT!?!?!????? MY HOME LAPTOP HAS A NAT, MY PHONE HAS A NAT, EVEN MY CAT HAS A MOTHER HUGGING NAT, AND THIS FUCKING INFRA HAS NO FUCKING NAT???????????????????????
ALready under loads of pressure, and the whole day is wasted. And now I'll be spending time to fucking UNDO everything I did today. Not try something new. But UNDO. And hour or more for just that...
I don't usually drink, but recently that bottom shelf bottle of Captain Morgan that smells and tastes like a bottle of medical spirit starts to feel very tempting.

Can anyone help me with this theory about microprocessor, cpu and computers in general?
( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)
How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.
Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.
Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?
Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.
Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B
On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)
Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.
The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.
My problems:
1. Is this all correct? Does this only happens?
2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.
Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(14 -
Sure just interrupt me constantly all day, I don't have anything important to do.

"Can you estimate how many questions my colleagues will have?"

Have this iOS maniac/UI guy/hustler at my office. (Refers to my first Rant,he's the fucker who always try to shove his iPhone to my face.) Hats off to him for knowing how to generate passive income and his hustling skill. But I hate that fucker. He always like to start a debate. He's always doing his sidejobs all the time. He sells staff online(even fidget spinner). He also does wedding photo shoots. Heard from a friend, he's a mediocre photographer but gets client by giving his potential clients lower prices than his competitors. He got a few connections and somehow always doing websites for his own client by going to codepen and copy pasting JavaScript from here and there. He doesn't know shit about programming. That fucker doesn't even know about closures. He literally doesn't know shit. Yet try to debate about with us regarding programming (wtf?) Always trying to get us to help him with his side paid jobs -when he encountered an error,he will immediately bug us- sometimes would interrupt us while we are busy with the company's stuff. If we don't help, he would slightly mock by saying things like "it's ok...I understand you guys are not that experienced yet..etc". The senior dev was pissed off the other day and emailed a super detailed complaint to the HR.
Note : He gets paid more by his photoshooting jobs on the weekend, he's only at this job for his future citizenship application. That fucker. He's the type of fucker that will definitely gets rich but gets hated by everyone. -
When all you want to do is spend your day at the office writing code and people interrupt you every 5 minutes for the most mundane things!2
-
just saw MS' presentation on bing+chatgpt. It could actually lead to something.
If someone could make a kanban-to-slack bot that can answer my Sprint status, it could vastly reduce my time spent answering the same question over and over to different people.
That is yet again AI doing what it was born to do: creative, artistic and engaging personal connections so that humans can focus on tedious calculations and repetitive labour.
If someone could make a bot to answer my emails for me I could spend the whole day without having to interrupt my workflow to interact with a single "professional" human!7 -
So i had a challenge with a js slider and i wanted my coworker to think along. I was trying to explain my problem and the steps taken so far but, as always, he wants to interrupt me after to sentences. He somehow always thinks he knows things better.
Dude let me first explain my shit before you start working on your solution. This is pure disrespect asshole! -
Usually when listening to music I have on my main Spotify playlist (using headphones), after a good 7-8h sleep followed by a good breakfast.
It's usually better when:
- there's no one around to interrupt me,
- I know what I'm going to do and
- no distracting noise. -
I'm often taking with co-workers and my supervisor, but it's extremely frustrating because they interrupt all the time before I've finished a sentence or if I misplaced one word while talking. They completely misinterpret what I say and I have to deal with their bickering once they think I said something incorrect.
Good grief people, just be patient.1 -
It's 2023 and smartphones can't even properly upload files in background.
When an upload is running in background while I watch YouTube or use other apps, the upload just stops at some point. The speed indicator in the top bar goes down to a few KB/s and I know immediately the upload has stopped well before it could have finished.
When re-opening the tab, I see a blank page and a loading bar. This means the tab has unloaded. Now I will have to re-select all those files again, which comes with its own troubles ( https://devrant.com/rants/9879401/... ).
Mobile browsers need to have a "protect this tab from unloading" option. Samsung already introduced a "keep open" option in the task switcher to protect individual apps from unloading in background. Why not do this on tab level?
Once the user locks their screen, this alone might interrupt the uploading process. On laptops and desktop computers, the upload keeps running in background.
Come on, this should be as easy as childs' play for billion-dollar corporations. Aren't smartphones "smart" enough to detect that a page is currently uploading files so its tab is not unloaded?
If smartphones can not accomplish this simple task that desktop computers and laptops can easily handle since the 2000s, it is a sad and embarrassing state.5 -

VSCode doesn't request permission to edit github workflow files by default. Because it's an OAuth app and not a token, I can't grant it scopes that it did not request. I am forced to use SSH or a personal token instead of VSCode's built-in Github authentication, but because there's no convenient way to have VSCode forget that it authenticated a repo, I am also forced to checkout my own repo again and push the changes across.
If you want your product to Just Work, then Just Use Open Processes that are easy to hook into, interrupt or partially replace. Nobody can think of everything. Not even Apple's or Microsoft's mighty designers. What everyone can do is to provide graceful failure modes and offer partial strategies. -
Reunions!
I'm a research fellow, so I have 2 teachers that are orientors.
We never have good reunions. They asks me every week to send a report of work done, but they never give me feedback. I ask what I can do next, sometimes they answer, sometimes they don't. So, some weeks I don't know what to do.
Almost everytime, they go to my room with somebody and ask to show the application. And with that,I need to interrupt my workflow, change one boolean variable (because we have a machine learning that is very slow, I have a if to throw the result I pre-calculated). After all this trouble, I need to speak (as he asked), but he starts interrupt while I'm speaking. -
A demon process is running inside me,
whenever I hear your name it's triggers an interrupt to brain,
Causing my brain to stop working and perform a context switching to think about you...
My memories are encrypted by your memories as like wanna cry...
And it demands to always think about you as a ransom...
I tried songs as a patch, But
I found that you memory encryption can't be fixed with any patches...
My heart is not strong as Linux ,
It's so week like Microsoft...
So please don't inject more bugs as my system can't sustain that...
I hope you will also get some disturbance like segmentation fault as you are trying to access my memories.. -
Anyone have those coworkers that completely interrupt people? I've found that a couple people i work with just were never taught to wait for someone else to finish. Doesn't help that they're really smart and also really opinionated.
How do you deal with these people? I've found steamrolling them or asking them to wait works, but only if you raise your voice a bit, which is mostly inappropriate, but easy to do on a web call.
Any suggestions for keeping this out of private life? I've found that i steamroll my friends sometimes even though i don't have any reason to, and I've become quite good at it...3 -
How the hell do you interrupt a download in Sublime FTP???!!! Any obvious hot key such as Ctrl+C doesn't work, and there's not a word about how to interrupt an operation in the docs of Sublime FTP.15

Programming Siemens PLCs is the same like using windows. Pretty comfortable - if you are fine with using it like 85% of the users.
Spent 10h today finding a way to realise an interrupt everytime a specific variable is set.. Every damned microcontroller can be used to! - _-
And therefore this typcial windows user question:
Is it not intended by Siemens or am I blind?
I mean i know you can use some prefabricated interrupts.. Like the cyclic interrupt OB.. I can't believe that it's not provided to freely create interrupts?!
Someone with an idea? -
I'd tinkered with computers for a long time but the breakthrough moment for me was a robotics class in elementary school where I programmed Legos in TC Logo.
That summer, I made a washing machine with multiple cycles and a door sensor to interrupt the cycles.
Soon after, I played with the code for Gorillas in QBasic to fix a race condition when running it on my 486 at home.1 -
Why do you lil' shits keep making LAYERS and LAYERS of unnecessary abstraction and then call it goddamn progress???
Dude what the fuck is this UEFI shit?!
Why the hell do I NEED to import a frigging library and read tons of boring and overly complicated documentation just so I can paint a pixel on the screen now uh??
Alright alright yeah so the BIOS is a little basic but daaaamit son if you want something a bit more complicated you make it yourself or install an OS that provides it! Like we've been doing it for years!!!
Dude, you don't get to know what a file system is until I tell you!
The PC be like:
"You wanna dereference the 0x0 pointer? There you go: it's 0xE9DF41, anything else?
You wanna write to the screen? Ok I have a perfectly convinient interrupt setup for that.
Wanna paint a pixel yellow? Ok, just call this other interruption. Theere we go.
And it only took four bytes and a nanosecond to do it."
That shit works, and if you want something more complex, but not too much, that still runs efficiently install DOS.
Don't mess around with the hardware pleeease.
We can still understand what's going on down there. Once UEFI steps in, it'll be like sealing a door forever. Long live BIOS damn it all!1 -
Put notifications in their place and carefully selecting which apps can interrupt you and at what times for what purposes.

I do some freelancing on the site, make a bit of cash and it's a bit different to the day job.
It can itself be pretty dull or boring, but at least I can drop the client when the project's over and try to find something interesting.
Anyways, I'm logged into a client Google account to do some domain admin on a GSuite account. Logged into Incognito so that it doesn't interrupt my usual session.
Get a bit distracted and sidetracked, end up searching for porn... in Incognito... in the client's session! 💀
Quickly clear search history and hope that does it!
Tell me someone else has done this too??4 -
I have joined a new company recently and I'm worried.
Really have worry because of my people skills and little doubt on the manager. I mean what do I know I just joined but still overthinking it.
There are people who speak confidently and I feel intimidated because in the casual conversations I don't feel like I can contribute at this point at least, it's been a week only. Other thing is as I do not know much about the work, I can't speak in the meetings. I know that I'm expecting a lot from myself here as I just joined but I have a history of being silent in the meetings and in my previous organisation I could deal with it as I got comfortable finally.
How can I be more interactive with people, given that some are cold?
About my manager, he is young. He definitely has a good IQ that's why he is a manager now.
The thing is, he talks a lot. Conversations are not 2 way, and he kept on saying things without even understanding that I'm overwhelmed. I have previously told him that I am overwhelmed, he listened, took 2 minutes and continued with his all work related talks.
I don't like the way he's stating his expectations from the time I didn't even join. He told me everything about the organization, on first day, he gave me a 2 months rough expectations of me. I don't agree with all the points he makes but it doesn't seem plausible for me to interrupt and say my thing. For example when he stated his expectations, I should have stopped him and politely tell that it's too soon we can discuss these things in upcoming weeks. But just because he continues rambling, I can't say it. It seems a small thing but I know it's not proper conversation and will create issues for me. As I have had similar kind of manager before, who used to ramble and didn't stop talking. But couldn't understand my problems etc. -
Just turned myself inside out why parsing data from serial didn't work. A full day, and 20 minutes before going home I realize the uart interrupt function was too slow. I just didn't get all chars...

It's these individually tiny annoyances in products and software that together form a huge annoyance.
For example, it's 2022 and Chromium-based web browsers still interrupt an upload when hitting CTRL+S. This is why competition is important. If there was no Firefox, the only major web browsers would, without exception, have this annoyance, since they're all based on Chrmoium.
I remember Chromium for mobile formerly locking scrolling and zooming of the currently viewed page while the next page was loading. Thankfully, this annoyance was removed.
In 2016, the Samsung camera software was updated to show a "camera has been opened via quick launch" pop-up window when both front and rear sensors of the smartphone were covered while the camera was launched by pressing the home button twice, on the camera software Samsung bundled with their custom version of Android 6. What's more, if that pointless pop-up was closed by tapping the background instead of the tiny "OK" button or not responded to within five seconds, the camera software would exit itself. Needless to say, this defeats the purpose of a quick launch. It denies quick-launching while the phone is in the pocket, and the time necessary to get the phone out could cause moments to be missed.
Another bad camera behaviour Samsung introduced with the camera software bundled with their customized Android 6 was that if it was launched again shortly after exiting or switching to stand-by mode, it would also exit itself again within a few seconds. It could be that the camera app was initially designed around Android 5.0 in 2015 and then not properly adapted to Android 6.0, and some process management behaviour of Android 6.0 causes this behaviour. But whatever causes it, it is annoying and results in moments to not be captured.
Another such annoyance is that some home screen software for smartphones only allows access to its settings by holding a blank spot not occupied by a shortcut. However, if all home screen pages are full, one either needs to create a new page if allowed by the app, or temporarily remove a shortcut to be able to access the settings.
More examples are: Forced smartphone restart when replacing the SIM card, the minimum window size being far too large in some smartphones with multi-windowing functionality, accidental triggering of burst shot mode that can't be deactivated in the camera software, only showing the estimated number of remaining photos if less than 300 and thus a late warning, transition animations that are too slow, screenshots only being captured when holding a button combination for a second rather than immediately, the terminal emulator being inaccessible for the first three minutes after the smartphone has booted, and the sound from an online advertisement video causing pain from being much louder than the playing video.
Any of these annoyances might appear minor individually, but together, they form a major burden on everyday use. Therefore, developers should eliminate annoyances, no matter how minor they might seem.
The same also applies for missing features. The individual removal of a feature might not seem like a big of a deal, but removing dozens of small features accumulates to a significant lack of functionality, undermining the sense of being able to get work done with that product or software when that feature is unexpectedly needed. Examples for a products that pruned lots of functionality from its predecessor is the Samsung Galaxy S6, and newer laptops featuring very few USB ports. Web browsers have removed lots of features as well. Some features can be retrofitted with extensions, but they rely on a third-party developer maintaining compatibility. If many minor-seeming features are removed, users will repeatedly hit "sorry, this product/software can not do that anymore" moments.
