I was 15 years old and the first year of high school. Everything was new to me and I was such a newbie. At that time I had 2-3 year of programming behind me at an institution where they taught competitive programming. And I knew something about computers. Not much but more than most of my school mates. At that time I wanted to become "super cool hacker".
So we had this very very thought teacher for history which was also our form master. She really knows how to explained everything about history and in an interesting way. But while she was teaching we also had to write down notes from her powerpoints that were on a projector. And occasionally she would wait for us to copy everything and then move on with her lecture. But sometimes she didn't. This was frustrating as hell. The whole class would complain about this because you couldn't take notes down normal, you had to do it at double speed.
But she got one weak spot. She was not very good with computers. Our school computers were locked in some kinda closet so that students didn't have physical access to a computer and were also password protected. So I came up with the plan to plant wireless mouse in her computer so that I could control her mouse. At that time it seemed like SUPER HACKER MASTER PLAN.
So I got an opportunity one time when she left the classroom and let closet where the computer was open. I quickly sneaked the USB of the wireless mouse in the computer and then go back to the seat.
So THE FUN began.
Firstly I would only go back in powerpoint so that all my schoolmates could write down notes including me. And it was hilarious to watch when she didn't know what is happening. So then I would move her mouse when she tried to close some window. I would just move it slightly so she wouldn't notice that somebody else is controlling mouse. And by missing X button just by slight she would click other things and other things would pop up and now she had to close this thing so it became a nightmare for her. And she would become angry at the mouse and start complaining how the computer doesn't work and that mouse doesn't obey her.
One time when she didn't pay attention to her computer and projector I went to paint program and drew a heart and wrote we love you (In Slovenian Imamo vas radi -> See the picture below) and one of my school mates has the picture of it. We were all giggling and she didn't know what is was for. And I managed to close everything before she even noticed.
So it got to the point where she couldn't hand it more so she called our school IT guy so that he would check her computer (2 or 3 weeks passed before she called IT guy). And he didn't find anything. He was really crappy IT guy in general. So one week passed by and I still had messed with her mouse. So she got a replacement computer. Who would guessed all the problems went away (because I didn't have another mouse like that). I guess when our IT guy took the computer to his room and really thoroughly check it he found my USB.
So he told her what was the problem she was so pissed off really I didn't see her pissed off so much in all my 4 years in high school. She demanded the apology from whom did it. And at that moment my mind went through all possible scenarios... And the most likely one was that I was going to be expelled... And I didn't have the balls to say that I did it and I was too afraid... Thanks to God nobody from my school mates didn't tell that it was me.
While she waited that somebody would come forward there was one moment when our looks met and at that moment both of us knew that I was the one that did it.
Next day the whole class wrote the apology letter and she accepted it. But for the rest of 4 years whenever was there a problem with the computer I had to fixed it and she didn't trust anybody not even our IT guy at school. It was our unwritten contract that I would repair her computer to pay off my sin that I did. And she once even trusted me with her personal laptop.
So to end this story I have really high respect for her because she is a great teacher and great persons that guide me through my teen years. And we stayed in contact.11 -
I keep putting my phone between my mouse and the wireless receiver and every time it makes it hard to move the cursor because of the blockage. So annoying!!3

Most successful? Well, this one kinda is...
So I just started working at the company and my manager has a project for me. There are almost no requirements except:
- I want a wireless device that I can put in a box
- I want to be able to know where that device is with enough accuracy to be able to determine in which box the device was put in if multiple boxes were standing together
So, I had to make a real time localization system. RTLS.
A solo project.
Ok, first a lot of experiments. What will the localization technique be? Which radio are we going to use?
How will the communication be structured?
After about two months I had tested a lot, but hadn't found THE solution. So I convinced my manager to try out UWB radio with Time Difference Of Arrival as localization technique. This couldn't be thrown together quickly because it needed more setup.
Two months later I had a working proof of concept. It had a lot of problems because we needed to distribute a clock signal because the radio listeners needed to be sub-nanosecond synchronous to achieve the accuracy my manager wanted. That clock signal wasn't great we later found out.
The results were good enough to continue to work on a prototype.
This time all wired communication would be over ethernet and we'd use PTP to synchronize the time.
Lockdown started.
There was a lot of trouble with getting the radio chip to work on the prototype, ethernet was tricky and the PTP turned out to be not accurate enough. A lot of dev work went into getting everything right.
A year and 5 hardware revisions later I had something that worked pretty well!
All time synchronization was done hybridly on the anchors and server where the best path to the time master was dynamically found.
Everything was synchronized to the subnanosecond. In my bedroom where I had my test setup I achieved an accuracy of about 30cm in 3d. This was awesome!
It was time to order the actual prototype and start testing it for real in one of the factory halls.
The order was made for 40 anchors and an appointment was made for the installation in the hall.
Suddenly my manager is fired.
Oh...
Ehh... That sucks. Well, let's just continue.
The hardware arrives and I prepare everything. Everything is ready and I'm pretty nervous. I've put all my expertise in this project. This is gonna make my career at this company.
Two weeks before the installation was to take place, not even a month after my manager was fired, I hear that my project was shelved.
...
...
Fuck
"We're not prioritizing this project right now" they said.
...
It would've been so great! And they took it away.
Including my salary and hardware dev cost, this project so far has cost them over €120k and they just shelved it.
I was put on other projects and they did try to find me something that suited me.
But I felt so betrayed and the projects we're not to my liking, so after another 2-3 months I quit and went to my current job.
It would've so nice and they ruined it.
Everything was made with Rust. Tags, anchors, RTLS server, web server & web frontend.
So yeah, sorry for the rambling.5 -
I HATE SURFACES SO FRICKING MUCH. OK, sure they're decent when they work. But the problem is that half the time our Surfaces here DON'T work. From not connecting to the network, to only one external screen working when docked, to shutting down due to overheating because Microsoft didn't put fans in them, to the battery getting too hot and bulging.... So. Many. Problems. It finally culminated this past weekend when I had to set up a Laptop 3. It already had a local AD profile set up, so I needed to reset it and let it autoprovision. Should be easy. Generally a half-hour or so job. I perform the reset, and it begins reinstalling Windows. Halfway through, it BSOD's with a NO_BOOT_MEDIA error. Great, now it's stuck in a boot loop. Tried several things to fix it. Nothing worked. Oh well, I may as well just do a clean install of Windows. I plug a flash drive into my PC, download the Media Creation Tool, and try to create an image. It goes through the lengthy process of downloading Windows, then begins creating the media. At 68% it just errors out with no explanation. Hmm. Strange. I try again. Same issue. Well, it's 5:15 on a Friday evening. I'm not staying at work. But the user needs this laptop Monday morning. Fine, I'll take it home and work on it over the weekend. At home, I use my personal PC to create a bootable USB drive. No hitches this time. I plug it into the laptop and boot from it. However, once I hit the Windows installation screen the keyboard stops working. The trackpad doesn't work. The touchscreen doesn't work. Weird, none of the other Surfaces had this issue. Fine, I'll use an external keyboard. Except Microsoft is brilliant and only put one USB-A port on the machine. BRILLIANT. Fortunately I have a USB hub so I plug that in. Now I can use a USB keyboard to proceed through Windows installation. However, when I get to the network connection stage no wireless networks come up. At this point I'm beginning to realize that the drivers which work fine when navigating the UEFI somehow don't work during Windows installation. Oh well. I proceed through setup and then install the drivers. But of course the machine hasn't autoprovisioned because it had no internet connection during setup. OK fine, I decide to reset it again. Surely that BSOD was just a fluke. Nope. Happens again. I again proceed through Windows installation and install the drivers. I decide to try a fresh installation *without* resetting first, thinking maybe whatever bug is causing the BSOD is also deleting the drivers. No dice. OK, I go Googling. Turns out this is a common issue. The Laptop 3 uses wonky drivers and the generic Windows installation drivers won't work right. This is ridiculous. Windows is made by Microsoft. Surface is made by Microsoft. And I'm supposed to believe that I can't even install Windows on the machine properly? Oh well, I'll try it. Apparently I need to extract the Laptop 3 drivers, convert the ESD install file to a WIM file, inject the drivers, then split the WIM file since it's now too big to fit on a FAT32 drive. I honestly didn't even expect this to work, but it did. I ran into quite a few more problems with autoprovisioning which required two more reinstallations, but I won't go into detail on that. All in all, I totaled up 9 hours on that laptop over the weekend. Suffice to say our organization is now looking very hard at DELL for our next machines.4

Which phones do you recommend?
Which have given you the fewest problems?
I want something with custom rom support so i can add my own problems (duh) and to make it prettier. Apart from that, the only other deal breakers are a lack of wireless charging (I have children who break everything) and an awful screen. I'm not really picky about anything else, but I do want it pretty.
Anyone have a phone like this that they actually like?17
