Paranoid Developers - It's a long one
Backstory: I was a freelance web developer when I managed to land a place on a cyber security program with who I consider to be the world leaders in the field (details deliberately withheld; who's paranoid now?). Other than the basic security practices of web dev, my experience with Cyber was limited to the OU introduction course, so I was wholly unprepared for the level of, occasionally hysterical, paranoia that my fellow cohort seemed to perpetually live in. The following is a collection of stories from several of these people, because if I only wrote about one they would accuse me of providing too much data allowing an attacker to aggregate and steal their identity. They do use devrant so if you're reading this, know that I love you and that something is wrong with you.
That time when...
He wrote a social media network with end-to-end encryption before it was cool.
He wrote custom 64kb encryption for his academic HDD.
He removed the 3 HDD from his desktop and stored them in a safe, whenever he left the house.
He set up a pfsense virtualbox with a firewall policy to block the port the student monitoring software used (effectively rendering it useless and definitely in breach of the IT policy).
He used only hashes of passwords as passwords (which isn't actually good).
He kept a drill on the desk ready to destroy his HDD at a moments notice.
He started developing a device to drill through his HDD when he pushed a button. May or may not have finished it.
He set up a new email account for each individual online service.
He hosted a website from his own home server so he didn't have to host the files elsewhere (which is just awful for home network security).
He unplugged the home router and began scanning his devices and manually searching through the process list when his music stopped playing on the laptop several times (turns out he had a wobbly spacebar and the shaking washing machine provided enough jittering for a button press).
He brought his own privacy screen to work (remember, this is a security place, with like background checks and all sorts).
He gave his C programming coursework (a simple messaging program) 2048 bit encryption, which was not required.
He wrote a custom encryption for his other C programming coursework as well as writing out the enigma encryption because there was no library, again not required.
He bought a burner phone to visit the capital city.
He bought a burner phone whenever he left his hometown come to think of it.
He bought a smartphone online, wiped it and installed new firmware (it was Chinese; I'm not saying anything about the Chinese, you're the one thinking it).
He bought a smartphone and installed Kali Linux NetHunter so he could test WiFi networks he connected to before using them on his personal device.
(You might be noticing it's all he's. Maybe it is, maybe it isn't).
He ate a sim card.
He brought a balaclava to pentesting training (it was pretty meme).
He printed out his source code as a manual read-only method.
He made a rule on his academic email to block incoming mail from the academic body (to be fair this is a good spam policy).
He withdraws money from a different cashpoint everytime to avoid patterns in his behaviour (the irony).
He reported someone for hacking the centre's network when they built their own website for practice using XAMMP.
I'm going to stop there. I could tell you so many more stories about these guys, some about them being paranoid and some about the stupid antics Cyber Security and Information Assurance students get up to. Well done for making it this far. Hope you enjoyed it.26 -
Yesterday I bought myself a PSP to relive some of my childhood memories, run custom firmware on it and so on. Unfortunately however, the battery on this one is seriously puffed up, and I need one in order to update the firmware from 5.50 CFW (the seller actually modded it too!) to 6.61 OFW (to then install CFW from there again).
I figured that I might as well have a kick at disassembling the battery for good measure, to take out its controller and power it from my lab bench power supply. I set it to 3.70V, double-checked the connections.. nothing. I raised the voltage to 4V, still nothing.
There is absolutely nothing wrong with the controller from looking at it. The magic smoke is still in there, all I did was removing the housing and snipping off the battery. I measured the cell voltage and it was only some residues at 0.01V. Might be internally shorted or something, normally even dead cells settle back at 3.7V unless you keep them shorted externally.
After seeing this so many times now with controllers, I'm starting to get a feeling that manufacturers actually program these things to look at the battery voltage, and when it reaches 0V, to just make the controller kill itself. Doesn't matter if the controller's electronics are still good, just fucking kill it.
If true, that is very, VERY nasty. It would also explain why batteries in laptops especially all have different form factors, despite having used regular 18650's internally for a very long time. It would explain why they're built like tanks. It would explain why manufacturers really don't want people in there. Yes there are safety issues and you're literally diffusing a bomb. Since recently we've also got space optimization.. anything for half a mm of thickness, amirite? But doing it this way is fucking disgusting. There is absolutely no reason for the controller to kill itself when the cell dies. Yet it seems like it does.
PS: I've posted the original picture on https://ghnou.su/pics/... now if you're interested. I noticed in my previous rant that devRant really squishes these down.12 -

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGGGGGGGGGGGGHHHHHHHHHHHHHH7 -
Gotta admit. Amazon fire tablets are awesome for cheap tinkering and installing custom firmware in it. Using 7 of them to use at my super efficient smart home (😎) and they don't break at all...
I wish they allow direct international shipping tho...2 -
Years ago was the first time I put custom firmware on our wndr3700 router, it hasn't crashed since.
I bought a wndr4700, faster, 5ghz, possibility for a hard drive.
It's been 3 years and still no custom firmware. -
TLDR; macOS wouldn’t update to the version I needed because I have a 3rd party SSD. All I needed was a firmware update only found deep within a google search and a secondary SO answer.
I have a video edit project this weekend. No big deal.
Except that the Final Cut Pro project was saved in the latest version of FCPX, for which I need latest MacOS version
As a music producer on the side, I had heard the new file system of MacOS High Sierra would possibly break audio plugins. I didn’t bother updating until now. Looked further into plugin problem, it would be simply a broken hard link which I can easily fix. No big deal.
Except that I have upgraded my MBP SSD from 256gb to this 3rd party 480gb SSD. macOS does not recognize this SSD as compatible with update. No big deal. Simple google search for a terminal command would do the trick.
Except that I found and tried several solutions, including wasting an entire hour updating the original ssd and booting from that to try to update it.
Nothing worked, but deep down in the google search, found in a secondary answer on SO, there was a link for a beta release of a firmware update for the SSD that took two minutes to install, and I was finally able to update.
That firmware update needs to be more prominent everywhere. Wasted well over 3-4 hours updating crap, swapping out SSDs, and googling when all I needed was a fucking firmware update.9 -
The near future is in IOT and device programming...
In ten years most of us will have some kind of central control and more and more stuff connected to IOT, security will be even a bigger problem with all the Firmware bugs and 0-day exploits, and In 10 years IOT programmers will be like today's plumbers... You need one to make a custom build and you must pay an excessive hour salary.
My country is already getting Ready, I'm starting next month a 1-year course on automation and electronics programming paid by the government.
On the other hand, most users will use fewer computers and more tablets and phones, meaning jobs in the backend and device apps programming and less in general computer programs for the general public.
Programmers jobs will increase as general jobs decrease, as many jobs will be replaced by machines, but such machines still need to be programmed, meaning trading 10 low-level jobs for 1 or 2 programming jobs.
Unlike most job areas, self-tough and Bootcamp programmers will have a chance for a job, as experience and knowledge will be more important than a "canudo" (Portuguese expression for the paper you get at the end of a university course). And we will see an increase of Programmer jobs class, with lower paid jobs for less experienced and more well-paid jobs for engineers.
In 10 years the market will be flooded with programmers and computer engineers, as many countries are investing in computer classes in the first years of the kids, So most kids will know at least one programming language at the end of their school and more about computers than most people these days. -
There seems to be a market for custom 3D printer firmware, consulting and debugging. What should I charge for something like this? I live in Germany and this will be a side quest.4

After waiting 3+ years, I finally found custom firmware for my netgear wndr4700.
LEDE project(based on openwrt), you are amazing.
Now just to figure out the 10000 options i have now.
Anyone that can help me?
Per example, my router should be capable of 300 mbit theory and 200 mbit practical.
But the custom firmware says max 150mbit.1 -
if anyone has firmware or any custom rom for htc 728, please help me. I need it asap. every file that I downloaded and tried was curropted while installing
Thanks!!2 -
Started with 3D-Printing last year, bought a cheap Creality Ender 2 and upgraded almost everything except the mecahnical parts.
Upgrades include a new Mainboard, stepper drivers, stepper dampers, custom firmware, new printed case, better extruder, OctoPI Server etc.
Oh yeah, and Animu ^^ -
YAYYY! I MADE IT!!
After several nights of playing with my new and very first custom mechanical keyboard, at last I could successfully get my long-time-dreaming keyboard!
I read the guilds, tutorials, even youtube videos to get walked through the process:
- I started with building my own layout on different websites, since they said that it would be easier to use online tools than to write codes by yourself in order to build your own keymappings, but the UI/UX of the first one I tried was so bad that it took me a great deal of time to understand how to use it and working on it is even more time consuming. Later I found another webpage which was less recommended, but could help me to do that a lot easier.
- Then, the result was compiled to a firmware file, which would be flashed into the kb's controller. Loading the file into the board was also tiring and got me exhausted totally! I tried all the "lazy" recommended ways (using Windows softwares) but received the same error all the time. When I almost lost all the hopes, I'd come to the least recommended way: typing a few command lines on Linux. And it worked! The keyboard just do what I want it to do miraculously.
What I learnt: never do complicated things on Windows, because they are suuuuuper simple on Linux!
P/S: Sorry for the bad lighting in my room and the tiny spacebar (the spacebar size is 7u which I don't have one right now). I just need a beautiful keycap set to make it perfect.5
