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!

I just had the most intense nerdgasm of my life.
So I'm learning NodeJS (11/10, super fun, totally recommend) and I already had a chat script written up but it was only available to my LAN. Im hosting it using my Raspberry Pi Zero, which is surprisingly fast, and obviously sips power. Anyways, I FINALLY figure out port forwarding (Comcast made things harder, as per usual) and for the first time in my young life, I chatted with someone half way across the country... Using the hardware I set up, running the script I wote, on the network I configured.
I could have sworn I was drooling.
Today was a good fuckin day.19 -
I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.
So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.
It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.
Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).
Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!
The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.
Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.
So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.
There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

devRanters do you think this is feasible as a fun/learning devRant community side-project?
Possible community side project: 'devie Stressball Trans-OceanicTrackable Voyage': So, my idea is based on the 2,000 year old concept of a message in a bottle. In fact, bottles from the Titanic were found 100 years after it hit the iceberg.
Pseudo: we pack devie into a bottle along with maybe a Raspberry Pi,GPS module, solar battery... Hopefully, it could send pings and we could track the journey. I am more a software guy than a hardware guy but I have played a bit with Pi and I know a few devs good with Pi's.I will also talk to the folds at Adafruit.
Here is an interesting paper I found in my beginning research. http://netlab.tkk.fi/u/jo/...
Also, I have seen low cost Raspberry Pi cubesats powered in outer space by solar.
Please let me know your thoughts if you think this might be possible. Also, if some of you might be interested in taking this learning journey. If we decide to try it I will purchase the hardware. Looking forward to your thoughts. Love this community!

When working with hardware some mistakes can be literally painful. Thankfully this was all during undergrad and I'm only around computer hardware now lol.
>Misprogrammed a software kill switch so a sensor that should not have been sending data was actually sending data which caused the system to activate a piston that went WHAM! into the face of a teammate working on replacing some part of it...
>Misprogrammed a controller so it drew too much power from the supply and the puny supply wires literally burst into flame and fell across my arm.
>Spun a 9000rpm CNC spindle the wrong way and caused an attached screw to go rocketing upwards instead of downwards and almost break the (pretty expensive) thing (uh...we were trying to use it as a power screwdriver essentially but I set the rpm to about 100x what I wanted and the direction wrong so yeah).
>Switched a -1 with a +1 in a robot's control system sending it careening into a teammate's leg... let's just say mecanum wheels are paaaainful.6 -
So I Bought this bio metric pad lock for my daughter. She excitedly tried to set it up without following the directions( they actually have good directions on line) first thing you do is set the "master print" she buggered that up setting her print. So when I got home I was thinking, no problem I'll just do a reset and then we cant start again.
NOPE !!! you only have one chance to set the master print! after that if you want to reset the thing you need to use the master print along with a physical key that comes with it.
What sort if Moron designs hardware / software that is unable to be reset. Imagine how much fun it would be if once you set your router admin password it was permanent unless you can long back in to change it. Yea nobody has ever forgotten a password.
Well they are about to learn a valuable financial lesson about how user friendly design will influence your bottom line. people (me) will just return the lock to the store where they bought it, and it will have to be shipped back to the factory and will be very expensive for them paying for all of the shipping to and from and resetting and repackaging of the locks and finally shipping again to another store. Meanwhile I'll keep getting new locks until at no cost until she gets it right.
poor design

Cracking old recovery CDs for the 9x/2000/XP era shines some light into how companies operated and when concepts came to be in that time:
Packard Bell: An EXE checks that you're running on a Packard Bell machine and reboots if it's not. How do we bypass it? Easy: just fucking delete it. The files to reinstall Windows from scratch come from...
...
C:?
Yup. Turns out Packard Bell was doing the recovery partition thing all the way back to the 9x era, maybe even further. Files aren't even on the restore disc so if your partition table got fucked (pretty common because malware and disk corruption) you were totally fucked and needed to repurchase Windows. (My dad, at the time, only charged at-cost OEM prices for a replacement retail copy. He knew it was dumb so he never sold PB machines.)
Compaq:
Computer check? Nope, remove one line from a BATCH file and it's gone.
Six archives, named "WINA.ZIP" through "WINF.ZIP" (plus one or two extras for OEM software) hold Windows. Problematic? Well... only because they never put the password anywhere so the installer can't install them. (Some interesting on-disc technician-only utils, though!)
Dell:
If not a Dell machine, lock up. Cause? CONFIG.SYS driver masquerading as OAK (the common CD driver) doing the check, then chainloading the real OAK driver. Simple fix: replace the fake driver with the real one.
Issues?
Would I mention this one if there weren't?
Disc is mounted on N:. Subdirectories work, but doing anything in them (a DIR, trying to execute something, trying to view shit in EDIT.COM) kicked you back to the disc root.
Installer couldn't find machine manifest in the MAP folder (it wanted your PC's serial before it'd let you install, to make sure you have the correct recovery disc) so it asked for 12-digit alphanumeric serial. The defined serials in the manifest were something like "02884902-01" or similar (8-2, all numbers) and it couldn't read the file so it couldn't show the right format, nor check for the right type.
Bypassing that issue, trying to do the ACTUAL install process caused nothing to happen... as all BATCHes for install think the CD should be on X:.
Welp.
well that was fun. Now to test on-real-PC behavior, as VBOX and VMWare both don't like the special hardware shit it tries to use. (Why does a textmode GUI need GPU acceleration, COMPAQ?????)4 -
Sometimes I just don't know what to say anymore
I'm working on my engine and I really wanna push high triangle counts. I'm doing a pretty cool technique called visibility rendering and it's great because it kind of balances out some known causes of bad performance on GPUs (namely that pixels are always rasterized in quads, which is especially bad for small triangles)
So then I come across this post https://tellusim.com/compute-raster... which shows some fantastic results and just for the fun of it I implement it. Like not optimized or anything just a quick and dirty toy demo to see what sort of performance I can get
... I just don't know what to say. Using actual hardware accelerated rasterization, which GPUs are literally designed to be good at, I render about 37 million triangles in 3.6 ms. Eh, fine but not great. Then I implement this guys unoptimized(!) software rasterizer and I render the same scene in 0.5 ms?!
IT'S LITERALLY A COMPUTE SHADER. I rasterize the triangles manually IN SOFTWARE and write them out with 64-bit atomic image stores. HOW IS THIS FASTER THAN ACTUAL HARDWARE!???
AND BY LIKE A ORDER OF MAGNITUDE AT THAT???
Like I even tried doing some optimizations like backface cone culling on the meshlets, but doing that makes it slower. HOW. Im rendering 37 million triangles without ANY fancy tricks. No hi-z depth culling which a GPU would normally do. No backface culling which a GPU with normally do. Not even damn clipping of triangles. I render ALL of them ALL the time. At 0.5 ms7 -
So I enventually spent 2 years working for that company with a strong b2b market. Everything from the checkouts in their 6 b2c stores to the softwares used by the 30-people sales team was dependant on the main ERP shit home-built with this monstruosity we call Windev here in France. If you don't know it just google and have some laugh : this is a proprieteray FRENCH language. Not french like made by french people, well that too, but mostly french like the fucking language is un fucking french ! Instructions are on french, everything. Hey that's my natural language okay, but for code, really ?
The php website was using the ERP database too, even all the software/hardware of the massive logistic installation they had (like a tiny Amazon depot), and of course the emails of all employees. Everything was just handled by this unique shitty and so sloooooow fucking app. When there was to many clients on the website or even too many salespeople connected to the ERP at the same time, every-fuckin-piece of the company was slowing down, and even worse facing critical bugs. So they installed a monitor in the corner of a desk constantly showing the live report page of Google analytics and they started panic attacks everytime it was counting more than 30 sessions on the website. That was at the time fun and sad to observe.
The whole shit was created 12 years ago and is since maintened locally by one unique old-fashion-microsoft dev who also have to maintain all the hardware of all the fucking 150+ people business. You know, when the keyboard of anyone is "broken" cause it's unplugged... That's his job too. The poor guy was totally overstressed on a daily basis and his tech knowledge just saddly losts themeselves somewhere in the way. He was my n+1 in a tech team of 3 people : him, a young and inexperimented so-called "php developer" who was in charge of the website (btw full of security holes I discovered and dealed with when I first arrive at the job), and myself.
The database was a hell of 100+ tables of business and marketing data with a ton of specific logic added on-the-go during years. No consistent data model or naming. No utf8. Fucked up relations that ends with queries long enough to fill books. And that's not all, all the customers passwords was just stored there uncrypted. Several very big companies and administrations were some of these clients. I was insisting on the passwords point litterally all the time, that was an easy security fix and a good start... But no, in two years of discussions on the subject I never achieved to have them focusing on other considerations than "our customers like that we can remind them their password by a simple phone call if they lost it". What. The. Fuck. WHATTHEFUCK!
Eventually I ran myself out of this nightmare. I had a few bad jobs already, and worked on shitty software already. But that one really blows my mind (and motivation for a time too). Happy it's over.1 -
When you, being severely understaffed, ask your boss and the president of the company to hire another embedded dev and a technical QA to work with you at the minimum, with hard proof of the need, because you work alone on a project that was initially poorly designed even though it is the core business of the company and that it bottlenecks literally almost every other sphere of the company...
and instead, he propose you to find by yourself 4 offshore unpaid interns to help you develop an EMBEDDED SOFTWARE that requires specific EXPENSIVE HARDWARE to run and test...
because paying new employees or even an intern is too expensive even though we had record sales the last few months and that the government pays 50% of salaries until the pandemic is gone.
Fuck this shit I'm out! I'm tired of not being paid enough to fix other people's mistakes. Have fun with your failing business. Btw, this is all your fault.2 -
Frustration Rant!
Because old hardware means learning the hard way sometimes, I've had to purchase more goodies.
On my last update, I installed the rs232 shield which may have inadvertently been wired backwards for Tx/Rx from what im used to. I assume it is backwards to most db9 serial ports because most Arduino or other projects you would do with a pi have serial "in" connections like old routers and devices that would be "controlled" rather than the other way around. Anyway, according to a video on youtube showing a guy turning an old machine into an IRC client via raspberry pi, this shield may be swapped. That means that instead of interfacing with the old machine via a null modem crossover cable, I need a straight cable with male db9 on both ends. I unfortunately tried using the null modem crossover cable which was reversing the reversed pins all over again. I hope these next few days are more fruitful now that I've bought a straight cable and db9/25 adapter.
The good thing is that I managed to get the pi to recognize its new serial port. I also dusted off my DOS skills and my serial card in the 5150 seems to work.
I literally banged my head after nothing worked. Im hoping that the tx/ Rx is solved soon.
Oh and that AT to PS/2 adapter will allow me to use by IBM original Model M Keyboarf rather than the fun model F.

(Warning: This rant includes nonsense, nightposting, unstructured thoughts, a dissenting opinion, and a purposeless, stupid joke in the beginning. Reader discretion is advised.)
honestly the whole "ARM solves every x86 problem!" thing doesn't seem to work out in my head:
- Not all ARM chips are the same, nor are they perfectly compatible with each other. This could lead to issues for consumers, for developers or both. There are toolchains that work with almost all of them... though endianness is still an issue, and you KNOW there's not gonna be an enforced standard. (These toolchains also don't do the best job on optimization.)
- ARM has a lot of interesting features. Not a lot of them have been rigorously checked for security, as they aren't as common as x86 CPUs. That's a nightmare on its own.
- ARM or Thumb? I can already see some large company is going to INSIST AND ENFORCE everything used internally to 100% be a specific mode for some bullshit reason. That's already not fun on a higher level, i.e. what software can be used for dev work, etc.
- Backwards compatibility. Most companies either over-embrace change and nothing is guaranteed to work at any given time, or become so set in their ways they're still pulling Amigas and 386 machines out of their teeth to this day. The latter seems to be a larger portion of companies from what I see when people have issues working with said company, so x86 carryover is going to be required that is both relatively flawless AND fairly fast, which isn't really doable.
- The awkward adjustment period. Dear fuck, if you thought early UEFI and GPT implementations were rough, how do you think changing the hardware model will go? We don't even have a standard for the new model yet! What will we keep? What will we replace? What ARM version will we use? All the hardware we use is so dependent on knowing exactly what other hardware will do that changing out the processor has a high likelihood of not being enough.
I'm just waiting for another clusterfuck of multiple non-standard branching sets of PCs to happen over this. I know it has a decent chance of happening, we can't follow standards very well even now, and it's been 30+ years since they were widely accepted.5 -
How often do we come across IT managers who don't plan their work properly?
I teach software development and programming at a vocational school. Our IT manager said that we got a certain budget influx and that he can procure new computers for our teaching facilities. I happily agreed and hinted that i would really like some new hardware with proper graphics cards so i could do a few small projects with Unreal engine, Unity3d or use adobe products without hardware lag. The new computers arrived about a week ago and then the "fun" started.
He had ordered some PCs with proper graphics cards and processing power and talked about putting them to up in my classroom, so wheres the "fun" i meantioned? He only ordered half a classroom worth of them - i guess the budget didn't allow for more. A week later i was supposed to move to a new room and was waiting for my new computers to be installed and yet the IT manager said that my computers would be moved along with me. I was appalled - what had happened to the new PCs he promised?
Turns out he had put em up in another building without notice, a teacher there wanted to do an extracurricular movie making activity (that included a bit of video editing at some point). That classroom is always in use so me getting more than 1-2 hours a week in there is nigh impossible.
In the end i got no new computers, hardware or software.... he didnt even bother to switch out the 2 "temporary" laptops i had in my classroom since 2 years ago due to a small shortage back then and even these have an old image that didnt include a third of the software i normally use.
PS. He had about another 2-3 classrooms worth of new PCs but those were promised to the other IT teachers back then....2 -
HEYYY!!
Glad to see ya all, how have ya been?
Gosh, it has been forever since the last time! I feel like I forgot about this platform too much, it feels good to have a place full of wonderful people to speak to, and you don't see those everywhere. I'm sorry I haven't been here much, it was mostly due to me not being able to practice programming much and thus falling back on tech stuff.
BUT - that period is now over. Maybe.
I'm gonna be more active on here, in the past recent years I've seen how bad most social medias turned out to be, with a few very special exceptions. I think devRant deserves more activity, so for better or for worse (hopefully better), I'm back!
I think my biggest problem right now is the need for a better PC, one Italians would call "a PC with the controcazzi", lol. A good one, is what I'm sayin. But would ya look at that, thr moment I start searching up for one, a friggin pandemic takes place and prices skyrocket! Ain't that fun. XD
I would probably have found an awesome PC build by now if I knew jack shit about hardware, but unfortunately I was always more into software than hardware. ^^"
So if anybody has any idea, I mean, I'm open to suggestions~ they'd be very appreciated, and thanks in advance. <3
But enough about that - how are you holding up? I hope you're doing good.
Misadventures and bad stuff happen, but I promise you we're all gonna get out of it soon. In the meantime, always remember to drink water, eat properly, keep yourself sanitized, exercise, and do things you love doing. That's what life is about. I'm looking forward to hearing from y'all, once again. 💙
Keep fighting the good fight, and kick ass! And chew gum, too.2 -
Everyone in this team calls everything a team effort, but once I start offering my help, they be like "no, I can do it. I know more than you".
Hmm. yeah, but you (sysadmin) use jQuery and vanillajs mixed. For example: $('#hello') and document.getElementById('hello').
Also you put console.logs everywhere, I don't mind putting console.logs in development, but not in production.
Oh and he copies the libraries to every folder that needs it, so there are at least 12 jquery libs in this project and the version is not even the same. Lol.... Please slap me to death.
There is another networkadmin that calls himself a (python) developer. He doesn't agree with my simplicity.
His work (just an example, changed names but you get the idea)
"A notebook that is used by x-department"
Model: Notebook
endpoint: department-notebooks
Model: DepartmentConfigs
Endpoint: notebook-department-configs
You won't believe what he put in 'department'configs, it's literally hardware vendor, model, versions.
Like... really? What the hell you doing man?!
Just have these models for example: device, department, vendor, product, category
We do not only have notebooks, but also servers, routers, switches and more.
His argument of having configs in the name is that they do more complex things. Hmm, I don't see it in the code and the data is messed up:
Microsoft, microsoft, micro soft.
He fixed it by hardcoding it in a select box. Mickysoft isn't the only vendor, fuck you!
fuck this team, fuck these people
Another fucking rant, a story was assigned to me. But that stupid fake developer worked on it immediately and message me he fixed it already. I guess he won't let me touch his baby.
Everything is just piling up. This team and people aren't fun at all.3 -
it would help if i had time to learn even a little more C, as I'm bumbling my way through the Linux kernel and GodMode9 (an amazingly powerful 3DS manip tool for everything from the SD card to the NAND to literally raw FIRM0/FIRM1 bootloader access) to try amd patch some code from GM9 into the kernel to handle the SD card *properly* so Linux 3DS doesn't constantly hang when reading/writing to the SD card, to enable Wi-Fi access (same bus location and similar bus structure as SD/NAND access, different processor,) enable NAND decryption and access (yes, really, NAND is encrypted via software, which is... ...fun...) and more.
tl;dr: the 3DS hardware, C, and others' code collectively make me wanna slit my fucking wrists. Hopefully my sacrifice allows higher-level programming languages to be visble for low-level jobs in the future.

So I now bought an iphone 6 again for development and tried just for fun to make it a daily driver and it feels really limited, especially because apparently theres no jailbreak yet for 11.2.5. (I feel near everything could be solved as soon as cydia etc. get fully released to the alibaba jailbreak)
I didnt even remember, that it doesnt have any option to have haptic feedback when typing, such a basic feature has to be jailbroken..? I thought I remembered that it had it, last time I had one - did they remove such a basic feature?
Also the fingerprint reader is really weird compared to other phones from the same year, first getting it to actually fill all fingerprint lines without saying "try again" or it trolling you and vibrating as if it recognized your finger, but actually didnt (really frustrating when its the last 2 lines...) - is a real challenge, might be that I have some mutant fingerprints, but when I asked my s/o to try it out, it also failed most of the times, so you have to position your finger in a very specific position for it to work, even if you add the max amount of 5 fingerprints.
Most ads on iphones feel HORRIBLE, the amount of lag some can add is incredible, wait till it loaded or youre fucked and besides using some shady adblocker vpn, theres no way to block them, without again - a jailbreak.
Another feature that I used many times on my android phone, is controlling it from the desktop, connect it via usb and then just use it for demonstration purposes on a projector or to instruct how things work - theres no such function without a jailbreak, even if you use osx..
Then theres the feature, that instead of just setting your cursor to a specific location, you have to hold and it zooms in, not sure if I just got too used to the android way of doing it, but I can see myself making less mistakes of where I positioned it with the ios way.
The hardware mute switch feels like a great feature, its just sometimes weird, so if you were inside an app that was playing sound and you mute it, it still plays it until you either close and open that app or just change to another one temporarily, so its not an actual hardware switch as I usually thought, more like a request to mute the phone.
The cable that comes with it is too thin, I am afraid to even unwind it, as it would probably break, so I had to get another one.
Please don't turn this into a shitfest from any of the fanboys, I really just wanted to share my image of finally being able to try it first hand again.4 -
I am trying to reverse engineer a fingernail hardening device for rapid hardware prototyping (becoming some kind of hardware developer I guess)
Since it is a fucking mess (all cables are black) they've chosen a weird construct to operate microcontroller on 240Vac (seems to be possible and made in very low energy consuming devices) i do not find any datasheet for one of the used products. It would help a lot but no. And messing around with high voltage is no fun.
I'm unsure if this fits as a dev rant since most/all I've read so far are software-related.

The universe has taken a cactus.
It proceeded to gift the cactus with a toxin that greatly enhances the stimulus of pain.
After the universe watched it's miraculous creation it decided to shove it up so far my arse that my gag reflex turned on and I puked a lot of cactus.
Didn't sleep well, weekend hardware migration finish, today an old server got moved.
Some part, most likely the redundant PSU, had a short circuit - decided to take the switches out... Which are the only non redundant hardware...
There was only one critical system in the whole rack, that was one redundant firewall.
Guess what happened..... Naaaa?
*drum roll*
For whatever reason, the second firewall didn't kick in, so large part of internal network unreachable as VPN was on the firewall.
:thumbsup:
That's not cactus level yet.
Spontaneously a large part of the work at home crew decided to call, cause getting an email wasn't enough.
So while all the phones were ringing and we had the joyful fun to carefully take apart a whole rack to check for possible faulty wiring / electric burns / hardware damage and getting firewall up and running again...
Some dev decided to run a deployment (doable as one of the few working at the company at the moment -.-).
I work from home, but we had a conference phone call running the whole time so I could "deescalate" and keep others up-to-date. So me on headphone with conference call, regular phone for calls, while typing mails / sms for de-escalation.
Now we're reaching cactus level, cause being tortured by being annoyed out of hell by all telephone ringing, the beeping of UPS (uninterruptible power supplies), the screaming of admins from the server room and the roaring of air coolers…
Suddenly said dev must have stood in the midst of the chaos… and asked for help cause "the deployment broke, project XY is offline"...
I think it was the first time since years that I screamed at the top of my lungs.
Bad idea (health issues)… but oh boy was it a pleasure to hear my own voice echo through the conference speaker and creating an echoic sound effect.
It was definitely worth coughing out my loungs for the next hour and I think it was the best emotional outburst ever.
I feel a bit sorry for the dev, but only a tiny bit.
After the whole rack thing, the broken deployment fixing and the "my ears are bleeding and I think I will never be able to talk again" action...
We had to roll out several emergency deployments to fix CVEs (eg libexpat).
This day was a marvelous shit show.
I will now cry myself to sleep with some codein.1 -
Hardware Developing.
My current school project where I build a gps thief lock for my moped had me realized one thing. I don't want to go into Hardware Developing. The first problem took me about 4 months until I finally gave up and solved it differently. And this goes on and on and on. You fixed something and the next day it doesn't work anymore for some reason. I never had this problem when coding. It's fun to do stuff with electronics but coding is just way more rewarding. Anyone else had the same experience?1 -

I gotta say I really love the beauty of being able to merge math, code, and hardware all in a well tuned symphony to make something awesome. Building an LQR controller for a custom quadrotor flight controller and it is just so much fun! -
Bought an Arduino and is finally able to learn how to make my software interact with custom hardware projects. Just wiring up a led and controlling it with software is amazing fun! Really looking forward to learning servos, motors etc.
Planning to make velocity sensitive midi drums with piezos in the future.4 -
God, playing SoulSilver has made me remember an era (or two, but I wasn't alive for one and the other was my childhood) where games were actually fucking *GOOD.* Some games can be absolute home runs now on rare occasion, but if I name consoles from these periods, you can INSTANTLY tell me at least one game that is pretty universally regarded as a best-ever.
Examples and predicted responses:
-Gamecube: Too fucking many to even count. Instant answers vary immensely, but everyone who's played games on this thing have one.
-Original Xbox: Halo 2 is the one instantly on one's lips, or maybe CE for some. Also JSRF.
-Dreamcast: SA2 or Phantasy Star or JSR or...
-PS1/2: Resident Evil, Spyro, Final Fantasy, Ratchet & Clank...
-PS3: Lara Croft games, Uncharted, Infamous... (this one's right on the border, it seems)
-NES: The fucking birthplace of modernized gaming.
-Genesis: Sonic games, obviously. Some may answer with arcade titles, too.
-SNES: Mario games. Mario Paint, SMW, SMW2, SMAS, a couple like Super Metroid or Kirby's Dreamland or F-Zero may come up too.
-N64: Banjo Kazooie, F-Zero GX, Waveracer, 1080, Zelda games...
-Gameboy (all systems:) Pokemon is the instant answer.
Now, a harder one:
-Wii U? Maybe one of the Mii game things? U-less games? Not many people remember the games for this system.
-Xbox One? Halo 5, pretty much. You probably played everything else on PC.
-PS4? The PS3 lineup, but without any soul? You played pretty much everything here on PC, too.
Is there a point to this rant? Yes. Kind of.
Games used to be great, not just due to better hardware, but due to people putting some goddamn heart and soul into making games, and due to creativity stemming from working on such limited hardware. It seems the more powerful consoles (and PCs!) get, the more gaming becomes a soulless cash grab to drain cash from wallets on subpar products with paywalls every 20 feet you have to clear to get the "full experience." Gaming has become less about letting people have fun and being creative with games and more about the bottom dollar, whether that be through making games as fast and as cheap as possible with as much paid content dumped on top as possible, or the systematic erasure of archival efforts to preserve gaming history. From what I read here on devRant, that seems to be the moral of anything computer-related as well. Computers are made to slow down and fail far faster than normal via OEM bloat and shitty OSes, and are used to constantly empty one's wallets with constant licensing fees and free trials and deliberate consumer ignorance. None of it's about having fun anymore. Fun seems to no longer have a place in computing at all.
If you take anything from any of the madman-esque loosely-structured rambling i'm saying here, make it that "the enemy of creativity is the abscense of limitations... and the presence of greed." Another message i'd like to leave you with is "start having fun when making things whenever possible, as it improves not just the dev process, but user experience, too." You can't always apply this, and sometimes you can never do so, but always keep it in mind.14 -
I am looking at replacing my Dell XPS 15 from 2019, but because I work 100% remote I am considering building a desktop developer rig instead of getting a new laptop. I have only had laptops since early 2000s, but thought it would be fun building something from scratch again. The problem is I have fallen tragically behind on everything hardware, and therefore looking for some pointers.
I don't want an RGB rainbow unit with 6 loud fans requiring a noise cancelling headset to work on. I want a top spec, stealthy thing that has all the goodies but also runs quiet. A decent graphics card that can run the latest games at a decent frame rate, but not the top of the line either.
Any tips on cases, motherboards, RAM, drives, fans and grahpics cards appreciated. The budget is roomy, comparable to a top spec Dell XPS 15 or ThinkPad X1 Extreme.12 -
I like how I'm the only programmer or tech-kid in my school, since everybody else is using there phones for SnapChat and texting in the middle of class.
While I'm over here talking about the insides of software and hardware like if I were the person that made them.
Seriously, I wish I could show my classmates that spending all of their time on apps and websites that sell your personal data is less fun (and basically stupid) than actually making what you want with nothing but a text editor and computer.
But oh well, 90% of my classmates are either assholes, cringy white girls (or Mexican girls), and the only people I find tolerable or even likable, are the people that don't talk much.

So, following up my last rant.
https://devrant.com/rants/2433162
I quit on Friday, this is what I said to my bosses.
"In the last week I had, 2 panic attacks, and I have 2 theories for this, one is that I have underlying psychological problems, the other theory is that we are under an impossible task, I choose to say now that I have to quit because I have psychological issues, but if you are willing to hear my other theory, that involves saying that meeting the deadline is not viable, then I can tell you that, so do want to listen that part?.
Bosses: No, we heard enough, we are going to have your contract terminated in order, and we will let you know when you can come and pick your paycheck."
So, that's them. Now about me and how I re-discovered GTD, or more precisely how I organized my whole weekend using taskwarrior with GTD, and why I think is going to be useful as a freelancer.
Before I feel good about telling you about my weekend I have to tell you a few things about myself.
I am a very impulsive person, I have a lot of energy in short surges, so I have to be able to maximize my activity when I'm in a surge, and I have to maximize my rest when I am not.
That's hard to do, it requires a balanced lifestyle, I am also very prone to being neurotic, and overwhelmed by the amount of stuff that I want to do.
And on top of that, when I am resting, I have surges of things that I want to have, do, or implement, it could be software related, as "Doing an app that will be the Uber of home services", to house improvements like, "I have to fix that leaking roof", and all the sort of stuff that happens in between hardware and software. That surge of consciousness doesn't allow me to have the proper rest that I need before I engage with activities again.
Because of this I have a very cyclic rhythm, with whole weeks burning my energy into doing stuff, and weeks resting doing very little and thinking too much.
Now about my weekend. Friday night I was browsing the web, and a thought came to my head. "The way you use your terminal, says a lot about your personality", and I got curious, so I searched for, "Show me your terminal", and found a post in dev.to to see all kind of nice terminal setups, from the very minimalist to very feature rich oh-my-zsh themes with plugins for git, aws and what not. One of these pictures really got my attention, a guy had set up his terminal to show him, how many task has he done in the day, and how many cups of coffee has he had.
So by investigating how he set up his terminal to show in the prompt the number of successfully completed tasks in the day, I found out that he was using taskwarrior, he was also kind enough to share the source code of his prompt setup, which I bookmarked to later incorporate that into my oh-my-zsh config.
After reading about taskwarrior, I also got a reference to GTD, I don't remember if this was one of those thoughts that I have and follow immediately, or if I read something that led me to a YouTube video summarizing GTD.
In the end, after watching that GTD video, I decided to give it a try to organize my life, and help me find a remote job, keep my house in order, plan my social activities as "hang out with friends", "visit mom and dad", and give the proper amount of attention to my GF, with whom I am deeply in love, and willing to spend the remaining of my years with her.
So my fist task was.
task add Ask for GF's parents blessing.
Which of course I have no intention of doing right now, but is one of the things that I will eventually have to do.
Then it started, I started adding tasks, and things to do, and go through the whole Capture phase of GTD.
Now it is a good time to write a small summary of what I think GTD is.
GTD is a life habit of organizing your life in todo-lists. And it was a very specific core method, that in the video summary that I watched was called CPR.
Capture, Process and Review.
Capture:
When you capture you just add your tasks to a bucket list.
So I took a notebook and started writing down everything that I wanted to have done. I also started to capture ideas as they came up to me, I did this by writing a telegram saved message in my phone, or directly adding it as a task in TW.
Process:
I read my telegram messages and put them into my task warrior list, then I started to organize my tasks into projects, breaking down every task that was not an atomic unit.
* And different projects started to emerge from this. One of them was project:Housekeeping.
And here's my screenshot of what I did this weekend, also the number of projects that I have, and all the things that I have to do in order to have what I think would be a very balanced, fun, and productive life.
You'll be able to see in the screenshot, that there's a blocked task, yes, tw allows you to organize dependencies too, so one task is delegated, and blocked by the delegation task.

Been working on redoing my desktop lately. Currently the specs are:
-FX-8350
-Gigabyte GA-970A-DS3P motherboard with a broken USB 3.0 header lmao
-GTX 660 (Gonna upgrade to an RX 580 at some point, I don't do any hardcore gaming so I know I don't need a top of the line GPU)
-Crucial BX500 240gb SSD
-WD 500gb HDD (gonna upgrade to a bigger one eventually)
-Some like $60 Dynex PSU I bought a while ago, waiting on my Corsair RM650x to come in
At this very moment, it's running Windows 7 Ultimate x64. Once I get to a point where I'm happier with the build, I'll switch it over to Linux and start ricing. It has Windows right now cause I'm just using it for some games and when I last fucked with the hardware, it was the middle of the night so I didn't want to spend too much time setting up a Linux distro the way I want it and everything right then, just putting that off for later (especially cause I use Arch btw)
I have been playing some Half Life 2 lately. I forgot how fucking fun that game is.
Aside from my PC, my birthday was technically yesterday (it's about 2:30AM as of writing this, and I've been up for a while, so I still consider it today). Now I'm 2 years away from being able to legally drink (and smoke since the law change, although I still do both anyways).
I'm gonna stop rambling. Life is fairly decent right now. Not too much to "rant" about except for shit with my roommates, but I won't bore everyone with that1 -
I had this dell server lying around and finally got to make a virtualisation server out of it.
It is now running xcp-ng as its hypervisor, with a CoreOS VM in it, containing a docker container serving xen-orchestra for managing the server.
Enterprise grade hardware really is a thing of its own. Also sysadmin type of stuff is quite fun. I look forward to be playing with it some more. :)1 -
Any gift recommendations. My birthday comes up in a few days and he asked what I wanted as a birthday gift(gifts are supposed to suprises but being able to choose is good still).
However I cannot ask for electronic gadgets. That knocks a lot of stuff of. The exception is that if something does not make me spend more time on the computer that is allowed. Kinda weird. For example I can ask for a printer or medical equipment like oximeters since that wont make me spend more time on the computer. Both of these examples were given by my father. I could ask for a new printer however we still have a printer but it is currently in the shop since it is not being used and the shops printer broke and is hell to replace since they need chips to verify toners and you need to get those chips separately from what my father told me and the shops printer should be repaired in a few months since lockdown was lifted a few days ago and I won't need to print something since everything is online and they don't need to show student projects yet.
Thia knocks a lot of hardware off since by definition if I am using hardware I still need to code it to do something which is more time on computer which is not allowed. So no fiddling with aurdino or rasberry pie or whatever is the most used hardware kit.
I can buy some course or a book to learn something but I already have problems with consistently learning c# with a good book which will lose value in November and that most topics I would like to learn like computer networking or some new language are practical which is more time on computer which is not allowed.
So the only thing I can buy are some books to enjoy reading for fun or some school books like a science digest book like Together with or the ultra popular maths reference book RD Sharma
So what things should I ask which comply with the rules my father has laid or just skip this thing1 -
My family got our first computer when I was in the 1st grade and I really liked it a lot.
After some years I saw someone code and I was like "What's that?". After they explained me what they were doing I was totally hyped and started searching tutorial videos on how to do simple stuff on VB (this was in my 7th grade, I believe).
By the end of my 8th grade I was introduced to a Computer Engineer that lent me a RoR book and tried to teach me the basics.
(Fun fact: around this time I was doing a Habbo clone server with a friend of mine so that we could play with our friends without all the other people poking around).
In high school I took a Computer Technician course where I learnt stuff like VB, C#, PHP, MySQL, some basic CSS/HTML plus some hardware fundamentals.
After that course I tried to enter college and I failed on my first try, so I took a gap year were I worked as a dev for my family's computer repair shop. It was really a good experience to have time for myself while working on what I loved.
Now I'm on the 2nd year of a Bachelor in Computer Engineering (It's more about software than hardware actually), currently working with Java, C, IA-32 Assembly and PL/SQL. My goal is to get a Masters in Software Engineering after it.
