It’s strategy week. And I have flown to A COMPLETELY DIFFERENT FUCKING COUNTRY.

In their wisdom, it has been decided that I, master of all knowledge (not!) will outline a roadmap for potential tech to come and where our pain-points are. They don’t have the slightest. CORP only now talks about AI and NOTHING sane is even closely is being addressed.

Fucking retards.

It is all for show.

It’s just a game for them.

Fucking holistic people.

Fuck leadership in IT with no actual knowledge of the pain of database upgrades. Fuck em!

It’s all pretending and using big words. I been in meetings where people actually use the words AI, autonomous and digital twin. In the same fucking sentence. Fucking imbecils! Do they even know how fucking impossible that is in a company like this where we struggle every-single-day with a tech debt that is actually incomprehensible. Yesterday I found code from 1978 in use, with no knowledgeable maintainers. Which is very cool but will be difficult, to say the least, to migrate. At the core of one of the deepest core processes at a specific site (we kind of make things). 1978. Thousands of lines of code.

We are NOT in a position at all to say things like this. Autonomous. We are NOT ready. We are NOT staffed and we will not be since we have NO money to hire the necessary workforce of 100 people it would take to actually do something useful. Even if we could hire them the time it would take to actually hold on to them would be too short. Since people are LEAVING THIS COMPANY SINCE IT/TECH IS NOT CONSIDERED TO BE IMPORTANT to the company.

Fuckers. I can take out half the factory in one minute.

Autonomous? AI? It is such a shitshow. And really, really depressing.

I wonder if they know. What would happen. If key persons was to decide to leave.

The care that has been put in place for this factory (HUGE FACTORY!!! HUGE!!!!!!!) system support is just really… well, crazy actually.

modern callback hell

Difference between 2023-01-01 00:00:00 and 2023-12-31 23:59:59 is 11 months, 29 days, 23 hours, 59 minutes, 59 seconds ; so almost a year (by one second)

Difference between 2023-01-01 00:00:00 and 2023-01-31 23:59:59 is the same, almost a month by 1 second.

Same for february (even with 28 being the last day).

But then, 2023-03-01 00:00:00 and 2023-03-31 23:59:59 gives me :
1 month, 2 days, 23 hours, 59 minutes, 59 seconds.

WHY, are there fucking 34 days in March ? Is this a bug ? Is it confused with February being the previous month ?
Why would PHP do this to me ?

Why the hell is it always so painful to work with dates, it's not even like I'm stretching the standard library or using raw timestamps to hack things together

I used the diff method of PHP 7.4 DateTime, is someone wants to try it

1. Being the only single wringable neck to keep 40+ websites afloat, plus 3-5 new ones coming in or being built each month all with an overseas team that uses Google Translate to communicate and who are also in an active war zone.
2. Being fired for being “too old” in my mindset about how to do things. I had just turned 40 and my boss was 24 and distracted by all the shiny frameworks when all the marketing person needed was a simple off-the-shelf CMS-based site to publish company offers.
3. Jumping into the middle of a HUGE clusterfuck of thousands of Slack channels, wikis, and Jiras and an outmoded content management system while trying to learn the ropes from a guy who has no time to teach properly and then who abruptly leaves the company with scant documentation on everything that he held mainly in his own head. And there was no way I.T. was going to allow him to have the ability in Zoom to make a video of his training sessions, for no discernibly good security reason at all.
4. Working for only 9 months at two separate companies for two separate frat dudes who could have been clones of each other and whose egos made them into seagull managers* in every sense.
5. Being told by a new employer that they’re hiring me to be the head of their new web team only to find myself shuttled off to obscure contractor roles at MegaCorp Inc and AcmeCorp Inc.

I have 17 more years of this shit ahead of me before I can retire.

*If you haven’t heard of this: Someone who flies in, makes a lot of noise, shits all over everything, and flies out leaving everyone else to clean up the mess.

Upwork is absolute GARBAGE.

PLEASE tell me alternative to find a job as a dev and work remotely. I have to work for foreign international software company.

I cant be working for my local city companies because the salary even for engineers is TRASH

I'm 2 months into my first dev job. Today, I was working on upgrading one of our products to React 18. Had a feeling my UI changes weren't being pushed to AWS so I wanted to test that. Changed all labels from ".. filter users..." to "shmilter shusers". Committed, then nearly pushed those changes for a PR. There are multiple lines of defence and only a 5% chance that no one would spot it but as soon as I realized that there's a small possibility that our customers would suddenly see "shmilter shusers" on their instances, I had an absolute fit. Maybe it's a "you had to be there" kind of thing but I don't remember the last time I laughed this hard.

What is it with over qualified, over certified consultants that go around spouting "best practises", and then come delivery time, have the most absurd bullshit that a junior with 3 weeks of knowledge in a particular subject would know what you just served up is nothing more then a pile of shit that will not be deployed even if your livelihood depended on it.

... Monday gonna be fun!

I'm notoriously bad at Git. By that I mean I REALLY REALLY SUCK AT IT. And I have the curse of short memory and an even shorter ability to retain the how-to, muscle memory knowledge of things if too much time passes.

So, I was staring down the gullet of merging two separate repositories onto my local machine and then pushing the result to a remote server. Not having the benefit of someone else to bounce this off of, and always finding the usual Git docs too dense and obtuse, I turned to ChatGPT to help me sort it out.

Guys, where has this been all of my life? I know it's not perfect and it can make mistakes. I knew that going into it, so I made preparations in case this failed. BUT. IT. WORKED! I feel like it has put me into the Star Trek:TNG universe where I can say "Computer, do the thing." and it does that thing. Here's the prompt I used and which it answered perfectly.

"Play the role of a git coach. I have two git repositories. One is on Bitbucket. The other is on GitHub. The branch named "master" on Bitbucket has the latest code. The branch named "master" on GitHub needs to be updated to what's on the Bitbucket "master" branch. Please write the series of git commands that I will need to accomplish this."

Others here hates how DevOps pushed parts of operations workload on Devs? Just this afternoon I have to fix a CI issue and then find a way to connect a microservice I built to production MongoDB; I'd be okay with that (I love to thinker with servers) if not for the fact which I have to do it trough leaky and badly documented abstractions put up by the customer. I was having a nice productivity streak but when I have to do this kind of shit the motivation quickly plummets.

Coming back here after years to rant about... myself.
TLDR: I fucked up and now have to call a thousand people as a dev, I'm not even getting paid for it and they all get crazy about a random ID that got assigned to them, so now I want to throw away all my electronics and become a skilift operator.

Stupid me deployed a project shortly before we have the largest amount of orders in the year. (Like 90% of yearly orders in a couple minutes cause they are sold out fast and people wait to order first)

I got this horrible legacy "plain self written framework php" project which I tried to upgrade state of the art.
There was one piece missing to upgrade everything and nicely deploy it to some fresh new servers which can handle the high load which peaks at the time orders open.

So I did it the day before orders open and... everything worked well! Nothing crashed.
I wrote my client to wait a little before he confirms the orders, since after confirmation each of the people who ordered will receive an email where they can choose a unique number which they'll receive as a sticker with the order.

Since it's an event my client is promoting, people will meet each other wearing those unique stickers and being able to identify each other online and in person with this number.

Suddenly my clients call me that "customers are complaining about that there is something wrong"
Turned out he confirmed all orders straight away and that part of the application which makes the number unique was broken on the update.
So everyone could chose any number (also taken ones) as his "unique" number.

In my panic, I told my client "It's my mistake, I'll deal with it of course and call the affected people in my free time, since it's my mistake you don't have to pay for it". (it's my largest client by far, am a freelancer)
Realizing when people can chose any number it'll not be a few ones who have the same, it's like almost everyone did chose "69", "1", "420", "88 (a scary amount of people)",... (with 69 being the number being chosen by most people btw, even more then "1")

So now I have to call about a thousand people telling them a new random ID will be assigned to them. I thought of course about mailing them, wrote a script that deals with the issue automatically, and FUCKED IT UP TOO so everyone is confused and the only way to deal with it is by a call basically.
And while I'm sitting here now for 2 days straight calling people in my free time about their random ID will have to change, I realized that some people are quite crazy about random ID's.
I'm talking about yelling and threatening because "is it too much to ask for a working website when ordering this expensive product".

I hate my life right now and am getting quite serious about throwing all my electronic devices away and become a skilift operator instead. Fuck the higher pay, it's not worth the shit, I wanna have only responsibility about one button to press while watching people fall on their face.

I am amazed. I witnessed (mostly heard) a 14 year old girl calm down a young adult female suffering an anxiety attack before I managed to push through people on the tram. She told her to close her eyes, breath, tell her what she smells, then open her eyes, name first thing that she sees, then look left, name first thing, etc.

This is called sensory grounding and it works. And yeah, what she did was pretty awesome but this isn't what amazed me the most. I asked where she learned that and she said "from a game about apes". And I knew exactly which game she meant. There's a title called Ancestors: The Humankind Odyssey and among many interesting mechanics there's one that puts the player in a state of anxiety when they venture into an unknown territory. The way to win that part is by analyzing surroundings by vision, hearing and the sense of smell before a panic countdown goes to zero. It's called "conquering your fear". Holly fuck, I played that and I didn't connect the dots. Are games nowadays teaching kids how to handle real life crisis? Where were those games when I was a kid??

Hello, world!

Just signed up for devRant...

So today our CFO stepped into IT and angrily proclaimed someone using tech@ e-mail and fake name is defrauding company funds buying themselves... "used female lingerie with extra virgin juice" (sic!).

I work for an IPSP, we handle finance for commercial services (think PayPal but smaller). One of our clients is a big platform where girls can sell items like bath water, used socks and more. CFO demanded our admins found out who and when connected to that website, what URLs and so on.

As mentioned, said platform is pretty big, hence, from time to time we help them with their service when they ask us to, that's why we have a tech@ account. Last month there was a minor issue with one of the banks, someone fixed it and, as per usual, made a small payment of €1 topping up the account wallet to make sure everything works. It was an intern whose will to live is still strong and unencumbered with experience so she jokingly wrote "panties juice, extra virgin" in the payment note. What she *didn't know*, however, is that admins on that platform used the very same account to test new billing system they've implemented and our CFO received an invoice.

Oh boy, my riskiest coding decision was certainly that one time when I refactored some 50k lines of critical legacy shit code in 3 days, straight up merged everything into master and then deployed to prod.
Luckily there was only one minor bug I had to fix after that... phew...
(To my defense: I was solo-working on it - the infamous CMS Of Doom™)

We aren't allowed to boil water BOIL WATER

"We have to get Climate Neutral until we decided for a plan the kitchen is closed"

FUCK YOU I JUST WANT TO ENJOY MY COFFEE WHICH I CAN'T DRINK IN MY OFFICE ANYMORE BECAUSE OF SAME BULLSHIT

I get it we have to become climate neutral but holy fuck this can't be part of the solution to not use the kitchen anymore....

I messaged a professor at MIT and surprisingly got a response back.

He told me that "generating primes deterministically is a solved problem" and he would be very surprised if what I wrote beat wheel factorization, but that he would be interested if it did.

It didnt when he messaged me.

It does now.

Tested on primes up to 26 digits.
Current time tends to be 1-100th to 2-100th of a second.

Seems to be steady.

First n=1million digits *always* returns false for composites, while for primes the rate is 56% true vs false, and now that I've made it faster, I'm fairly certain I can get it to 100% accuracy.

In fact what I'm thinking I'll do is generate a random semiprime using the suspected prime, map it over to some other factor tree using the variation on modular expotentiation several of us on devrant stumbled on, and then see if it still factors. If it does then we know the number in question is prime. And because we know the factor in question, the semiprime mapping function doesnt require any additional searching or iterations.

The false negative rate, I think goes to zero the larger the prime from what I can see. But it wont be an issue if I'm right about the accuracy being correctable.

I'd like to thank the professor for the challenge. He also shared a bunch of useful links.

That ones a rare bird.

Both Conservancy and the Git project are aware that the initial branch name, ‘master’, is offensive to some people and we empathize with those hurt by the use of that term.

Offensive my butt. It's not like any developer alive today had experienced the life of a slave. It's all in the past. Should I get offended by imperial Japanese flag?

I have a confession to make.. I have sin.. after 8 years of coding in the dark I've joined the light..

How did this happen? Well whenever I would decide to change my dark theme to another dark theme in VSCode, normally I would arrive at the light themes in the list, and for some reason the reading felt more pleasing to my eyes, so I started researching as to whats the best theme for the eye, and why does the light theme feel "more right"?

So it turns out that there isn't any difference for the eye, but that maybe because of the white paper black letters the eye finds it easier to focus on the letters rather than visa versa.

And here I am coding in the light for a month now and it feels great I guess?
Keep in mind I was one of those that would see light theme users as mudbloods and muggles. But I can't deny that the light theme + blue filter makes my eyes more rested.

meeting with PM, 1:1
me: well, to be honest, i think there is also some room for improvement concerning communication in our meetings. the discussion culture in our meetings could be more open.
PM: what do you mean? i don't know what you're talking about.
me: well, i feel sometimes that in meetings, you overly challenge what colleagues suggest. on the other hand, it's really hard to argue against what you are saying. what you say is often like engraved into stone and it is hard to argue against that, but the next day you might have changed your mind again and then things are different, but engraved into stone again.
PM: hmm. can you give me some more concrete example?
me: well... (gives some examples) it's just that it would be nice if you would listen more to what people say in meetings and try to understand what they actually mean or want to say, instead of saying "nah, that's not how we do it" or "no, that's wrong"... just.. well, have more trust in our skills, try to find out what people mean before you discard what you think they said... a bit more of appreciation and openness.
PM: oh, i can tell you, i'm the MOST open manager in this whole company.
me: ...
PM: but anyway, i will think about it.
me: well... okay. also i see there are some challenges within our team concerning intercultural communication. i mean, communication between Germans and Indians is in general a bit problematic in our company, and maybe it is a good idea to have some workshop together concerning intercultural competences... i think we could benefit from that. (what i actually meant is, these problems exist, but currently i see them more on his side or between him and Indian colleagues, because e.g. he tends to harshly criticize people in daily standups, and if we "direct" Germans already feel affronted by his behavior, how must Indian guys feel about it? in fact, 2 Indian devs already left the project. also communication doesn't really work well, in a way that there's often a great mismatch between his expectations and what Indian devs actually think they have to do)
PM: i can tell you, i really understand our Indian colleagues, i really know how to work with them. also, their working style has greatly improved since project start. (which doesn't feel quite right after he totally ripped apart the work of one guy in the last sprint review meeting)

of course, that's not the whole conversation, but it's kind of a symptomatic example for the whole situation...

"It works on our end", the sentence that made me lose my shit.

I've been working on a project were we're supposed to integrate an API into our system.

When trying to get some user id's (UUID) from said API, we got a type-error in the response (???), so I called their integration support and asked what the fuck they were doing (not really, i was kinda calm at this point).

The answer I got was following:

Integration guy: "Uh, bro, like, I don't even know, it's probably on your end"

Me: "We literally used this endpoint with the same parameters yesterday, and got a result we expected. I noticed you updated your API this morning, did you make any major changes?"

Integration guy: "Yeah we changed the type of user id from string to number"

Me: "So, you changed the type of a UUID (uuid4) from string to number? How did you not think that would be an issue? I can see in your forums that everyone else is having the same issue."

Integration guy: "Nah, it's probably a bug in your code, it works on our end"

Me in my mind: *IT WORKS ON YOUR END?!? IT DOESN'T FUCKING MATTER IF IT WORKS ON YOUR END, FUCKTARD.*

What I actually said: "Uhm, I'm not sure if works on your end either, I'm not even sure how this change made it to production. But hey, thanks I guess, bye."

WHY AM I NOT ABLE TO YELL AT PEOPLE WHEN THEY ARE BEING RETARDED???

But really though, when you're maintaining an API, you shouldn't fucking care if things work on your end in your dev environment. What matters is how it works in production, for the end user/users.

And I know that 99% of cases it's the users fault by entering the wrong parameters or trying to request with wrongly setup auth and what not, but still.

Don't ASSUME nothing's wrong on your end. It's your fucking job to fix the issues.

And guess what? The problem was on their side.
I'm going fucking bald.

User: We have been dealing with this bug for a month now! How come nobody has fixed it?

Dev: Who did notify about this issue?

User: You’re not listening we have been dealing with this for a MONTH!

Dev: When this issue first occurred did you tell anyone?

User: Yes!

Dev: Who?

User: …. Ok I don’t remember but I know I said something to someone. Anyway it doesn’t matter, your job is IT so how come this isn’t fixed?

Dev: Did you have an email? Ticket number? Teams message? Any record of where this was dropped?

User: I think you’re missing the point. We haven’t been able to do out jobs for A MONTH. We’ve just been sitting around completely helpless. We’ve been trying to figure a system using paper and pencil to replace the electronic one but it’s too complicated. How come this wasn’t fixed the second it happened?

Dev: It’s hard to respond to an issue if it’s not brought to out attention.

User: Ok but we are too busy to create a ticket! We have a million things to do and we can’t do any of them because your app doesn’t work! We’ve been sitting here telling each other how terrible this system is AND IT HAS BEEN A MONTH.

Dev: …. Yeah I got that

I am a female manager at a small, mostly male company, and directly manage several people (all male). One of the six has worked for me for multiple years. Since he began his employment, I always felt he had a “crush” on me and kept my distance (as much as I could as his manager).

His crush has gotten increasingly more obsessive over the past year: constantly staring at me, using absurd reasons to contact me through email/messenger/texts, whether at work or evening/weekends, and getting extremely emotional/upset if I do not frequently talk with him or provide feedback for his every task. He never says anything inappropriate or makes any advances but is making me increasingly more uncomfortable.

My tendency to avoid the employee combined with my obvious annoyance with his increasingly absurd reasons to interact with me is reflecting poorly on my management skills — to the extent that my manager is questioning my abilities to manage.

This Old Fart looks at webpack prod ver of my code and be like change the way you write code because I can't read it.

Once had a manager who would refuse to review anything on the basis he "didn't have enough time". Not just code reviews, but also customer comms, support messages, documentation etc. - anything that it's good to get more than 1 set of eyes on. This was a small startup so me working pretty much solo - it wasn't like there was anyone else able to review anything like this.

Fair enough, you might say. He trusts me. Just put it out there.

...but then *as soon as* it was published / sent / committed / whatever, he'd then magically find 5 minutes to glance through it and point out how rubbish / unhelpful / ridiculous the work was, and how it should have never gone out in the first place, and why didn't I read through it before sending as I'd clearly realise how stupid this was.

After a few rounds of this I actually flipped out on him in the office, called him out on his BS and told him to think for 2 seconds about how ridiculous this situation was. In fairness to the guy he did back down, take note and it didn't happen again, but damn, those times were some of the most frustrating of my career to date.

I just started but I'm already tired.

For some years I have worked in the industry, not a lot, I know right but I really wonder how do you deal with all "not code-related" bullshit.

IT should be a dynamic field but somehow it is stuck inside the business logic which is all about the money and that does not take care of the real matter which is "code engineering".

- Most of the projects I have seen are an utter mess.
- No real structure
- Code is literally thrown somewhere to make stuff works and fix bugs
- Features which should require X amount of time are planned and shipped earlier ignoring best practices.
- The customer changes idea every week
- Nobody wants to pay for a reasonable architecture but prefer to keep financing un-maintainable projects that only God knows where they have been made (presumably in Hell)
- Juniors devs with no real senior following them committing unreasonable stuff
- Seniors devs thinking they are but they aren't.
- Company that keeps delivering projects even if they have not the required amount of people to make it in time.

Seems like nobody wants to stop and take time to think and make the right decisions. I see people running around me like crazy ants.

But, above all, what really kills me deep inside is HR. You are looking for "dynamic" "talented" "cool" devs but you are not willing to pay them enough.

Should I talk about LinkedIn?

Oh, God... Even the worsts companies sound like they are into Fortune 500. I feel so much hypocrisy here.

I have worked for big and small IT companies.
In the end, is all about "inside politics", everything which is getting financed is not because of usefulness but because of "relationship".

I started coding when I was really young.
After ten and more years, I finally take the job of my dreams but everything is shuttering under my feet.

If you have some words of wisdom, I'm here to hear you.

PS.
I'm not a native English speaker, I apologize for any mistake.

To replace humans with robots, because human beings are complete shit at everything they do.

I am a chemist. My alignment is not lawful good. I've produced lots of drugs. Mostly just drugs against illnesses. Mostly.

But whatever my alignment or contribution to the world as a chemist... Human chemists are just fucking terrible at their job. Not for a lack of trying, biological beings just suck at it.

Suiting up for a biosafety level lab costs time. Meatbags fuck up very often, especially when tired. Humans whine when they get acid in their face, or when they have to pour and inhale carcinogenic substances. They also work imprecisely and inaccurately, even after thousands of hours of training and practice.

Weaklings! Robots are superior!

So I replaced my coworkers with expensive flow chemistry setups with probes and solenoid fluid valves. I replaced others with CUDA simulations.

First at a pharma production & research lab, then at a genetics lab, then at an Industrial R&D lab.

Many were even replaced by Raspberry Pi's with two servos and a PH meter attached, and I broke open second hand Fischer Sci spectrophotometers to attach arduinos with WiFi boards.

The issue was that after every little overzealous weekend project, I made myself less necessary as well.

So I jumped into the infinitely deep shitpool called webdev.

App & web development is kind of comfortable, there's always one more thing to do, but there's no pressure where failure leads to fatalities (I think? Wait... do I still care?).

Super chill, if it weren't for the delusion that making people do "frontend" and "fullstack" labor isn't a gross violation of the Geneva Convention.

Quickly recognizing that I actually don't want to be tortured and suffer from nerve damage caused by VueX or have my organs slowly liquefied by the radiation from some insane transpiling centrifuge, I did what any sane person would do.

Get as far away from the potential frontend blast radius as possible, hide in a concrete bunker.

So I became a data engineer / database admin.

That's where I'm quarantining now, safely hiding from humanity behind a desk, employed to write a MySQL migration or two, setting up Redis sorted sets, adding a field to an Elastic index. That takes care of generating cognac and LSD money.

But honestly.... I actually spend most of my time these days contributing to open source repositories, especially writing & maintaining Rust libraries.

So this chick has been super nice to me for the past few months, and has been trying to push me towards a role in security. She said nothing but wonderful things about it. It’s easy, it’s not much work, it’s relaxing, etc.

I eventually decided I’m burned out enough that something, anything different would be good, and went for it. I’m now officially doing both dev and security. The day I started, she announced that she was leaving the security team and wouldn’t join any other calls. Just flat-out left.

She trained me on doing a security review of this release, which basically amounted to a zoom call where I did all of the work and she directed me on what to do next, ignored everything I said, and treated me like an idiot. It’s apparently an easy release. The work itself? Not difficult, but it’s very involved, very time consuming, and requires a lot of paper trail — copying the same crap to three different places, tagging lots of people, copying their responses and pasting them elsewhere, filing tickets, linking tickets, copying info back and forth to slack, signing off on things, tagging tickets in a specific way, writing up security notes in a very specific format etc. etc. etc. It’s apparently usually very hectic with lots of last-minute changes, devs who simply ignore security requests, etc.

I asked her at the end for a quick writeup because I’m not going to remember everything and we didn’t cover everything that might happen.

Her response: Just remember what you did here, and do it again!

I asked again for her to write up some notes. She said “I would recommend.. you watch the new release’s channel starting Thursday, and then review what we did here, and just do all that again. Oh, and if you have any questions, talk to <security boss> so you get in the habit of asking him instead of me. Okay, bye!”

Fucking what.
No handoff doc?
Not willing to answer questions after a day and a half of training?

A recap
• She was friendly.
• She pushed me towards security.
• She said the security role was easy and laid-back.
• I eventually accepted.
• She quit the same day.
• The “easy release” took a day and a half of work with her watching, and it has a two-day deadline.
• She treated (and still treats) me like a burden and ignores everything I said or asked.
• The work is anything but laid-back.
• She refuses to spend any extra time on this or write up any notes.
• She refuses to answer any further questions because (quote) “I should get in the habit of asking <security boss> instead of her”

So she smiled, lied, and stabbed me in the back. Now she’s treating me like an annoyance she just wants to go away.

I get that she’s burned out from this, but still, what a fucking bitch. I almost can’t believe she’s acting this way, but I’ve grown to expect it from everyone.

But hey, at least I’m doing something different now, which is what I wanted. The speed at which she showed her true colors, though, holy shit.

“I’m more of a personal motivator than anything,” she says, “and I’m first and foremost a supporter of women developers!” Exactly wrong, every single word of it.

God I hate people like this.

I was hired as Project Manager.

After few days, I discovered that:
- I didn't have a team
- I was also the main and only developer
- all the projects I was assigned to were late
- I was also the account manager and I had to explain the delay to the customers.

And no, the salary didn't make up for the daily loss of reputation.

I lasted more than I thought, when I discovered that customers were not interested in delivery either, as it was a kind of money laundering scheme

"I keep complaining to you guys every day about this bug and nothing happens!"

Firstly, it ain't a bug. Secondly, you're not complaining, you're whining. Thirdly, complaining is a bloody limited resource. If you do it once a year, everyone's going to sit up and take notice. If you do it daily, it's just "Duncan having another moan", and the only thing anyone will do is play "what time of day will Duncan rant" sweepstakes.

A while back, I had a lot of telemarketers were calling me daily, and I mean A LOT of them.

I got so frustrated with he calls that I decided I had to figure out a better way to handle those calls.

At the time, I was working with a PBX software called Asterisk, which is used to handle hardware interfaces and network applications for phone calls.

I needed a suitable side project and there was a version of Asterisk designed for Raspberry Pi, so I made a fun little answering service for myself.

Whenever a telemarketer called, I asked them to call back later, but to "my personal number", and gave them the number to my phone robot. (which had a pre-paid SIM card in a GSM dongle mounted)

When it received a call, it would play a pre-recorded phrase, wait for 1000 ms of silence and then play the next phrase.
After all 16 phrases had been played, it would start from phrase 7 again and repeat until the caller gave up.

I had this set up running for a while, and then added another robot for english speaking callers.

The calls stopped after a few months.
MISSION ACCOMPLISHED!
