Tried to install hackintosh. So I partitioned one empty partition and the other with windows with my school files.

I then accidentally defragmented my windows drive to Mac Os Journal Extended. I lost a lot of important school files which set me a few weeks back.

Almost bricking a Linksys WRT54G-TM Tmobile branded router trying to flash DD-WRT. Turns out the customer's laptop battery was just defunct and luckily Windows gave a battery warning or else it was seconds away from going off mid-flash and I forgot about it yet I MYSELF worked on it hah!

Actually did brick a Netgear WNDR3300 trying to flash an updated DD-WRT. Had it in recovery mode, could've possibly fixed but then turned it off and it was gone forever.

Also, failing to back crap up then wiping a drive (in my main machine) containing 4 or 5yrs of work on my various programs. Now I have another machine that hosts a mercurial install containing all my code. The only code that touches my main machine now is what I'm working on, and even that is checked back in after each change, small or large. Though better than before, I still need to implement something that backs all that code up to somewhere offsite.

Nothing too bad really. When I was like 10 I was staying at my parents friends and they had a 486 that wasn't working in the room. Seeing I had been using a 486 at home I though I could fix it haha. I took one look at the back and decided to flick that little red switch on the powersupply (read voltage settings). Turn on, flash, bang (huge fright), smoke, put computer back and and never told anyone ahahahah. Was mortally scared of powersupplys till the age of 13.

I almost formatted a HDD holding every customers restaurant menu designs from a small printers shop once, when I realised what I had just done I pulled the power with an instant sweat appear on my forehead

Luckily slow XP and fast reflexes saved the day

I was not so lucky a few years ago when I was backing up full outlook emails/profiles etc for every machine in head office and somehow managed to not backup the CEO/Boss' outlook before we switched servers/domains... was not a popular boy for a while

Lol, I've formatted the wrong drive on a couple of occasions. I get through several stages of emotions when it happens. Mortification, anger, then acceptance.

Sorry had to quote this, thats the best thing ive read all week

Mortification, anger, then acceptance.

I can see that process in my head, as i suspect, can many

What are your worst computing mistakes?

Building one.

That's the best thing you can do! Hmm, my worst mistake has to be installing Ubuntu (or for that matter, any Linux distro. I have tried). Sure, it's free, but it always broke after the updates, which required tons of time to fix (or reformat) or Linux experts telling me "I'm doing it wrong" rather than helping to fix the problem. Time = money, so Linux != free

We had a client who we were building two custom PCs for. One was to be shipped to Washington state, the other to Texas. I had everything perfectly setup so they could literally open up the box, turn it on, and VPN, Outlook, everything was all setup.

I shipped each one to the wrong location, priority overnight. About a $600 mistake.

run a sql script on a wrong db schema.

deleted important tables on the development database.!!

back up was 2 months old

:rolleyes:

I can sympathize there - about 2 months ago, accidentally left out a where clause on a sql script, ended up deleting every entry on a table...

Thought to myself "Dammit!...ah well, I'll just have to recover it from the backups..."

Checked the backups (which I thought had been running daily) - last backup was sometime in March...

Lesson learnt: Backups! Backups! Backups! Every morning now, I check and double check to make sure both our on-site and online backups are running.

don't really have many. Mostly formatting USB sticks I don't mean to. The only major thing I did was quickly fixed with a call to intel, was I tried upping the speed of my ram to 1333 which my MOBO supported but my RAM didn't (or other way around) and my PC would reboot right after post. Clearing CMOS didn't fix it, had to call intel and ended up having to reset the CMOS by moving a Jumper from operation to reset mode and reboot and reset up the CMOS and BIOS settings.

I remember at primary school some kid told me that there was a game creator program in the control panel in windows 3.1.

I vividly remember the day being the longest ever as I waited to get home to find this program and make a game. I spent hours looking everywhere in 3.1 (although not many places to look - I was a kid) and literally clicking every possible thing I could.

Not really a bad mistake, but funny nonetheless. I never did find that game maker....

while hotswapping a drive I accidentally plugged the power connector the wrong way. bye bye hard drive. luckily it wasn't my main drive or i would have been even more furious.

oh and another time I was resizing a partition on an external HD, and i accidentally unplugged the USB cable before it was completed...

i had to spend hours recovering my data.... not fun.

    • Microsoft is making Windows 11's context menus faster, simpler, and configurable

      I think the car analogy is more this: Left hand drive, basic commands on the left side of the infotainment screen. Right hand drive, basic commands on the right side of the infotainment screen. Granted, you're not swapping between the two often so it's doesn't really work. But it's to do with the proximity of you (your mouse, or the driver) to the controls.

      I mean, the old one was broken and so stupidly complex for many users, so I don't see that as a feasible option. A context menu needs to be simple to use, and for me the Windows 11 style actually worked really well for me, and many others. I used to have to scroll the damn context menu just to get to "file properties" in Windows 10. That was not a good experience, and I'm sure you'd agree. What they're trying to do is make it the best of both worlds, as clearly you'd prefer the Win10 style. I'm curious how they're going to do this.

      The "Show more options" has its place, as does the simpler context menu, but it should perhaps be a separate fly-out rather than relaunching the entire, old context menu. The old context menu was getting absurd in Windows 10. Often I'd have to make the context menu scroll just to get to "File properties" on my old laptop. Even without much installed, the amount of items was just too much. It's a context menu, not a "do all" menu. Making it configurable is fraught with challenges too, so I'm interested to see how Microsoft tackles this one.

      I don't hate the new menus, I am not a fan of the lack of features and how they went live when they clearly are not complete. The menu itself presents much better than the previous - but what's lacking (IMO) is: 1) Any kind of automated manipulation such as: "this goes on the new menu because you use this feature more often on this filetype" "this is rarely used and will fall back to the old menu" 2) Any kind of user manipulation such as: "a UI to add/remove/order items to the new menu"
