One of our web developers reported a bug with my image api that shrunk large images to a thumbnail size. Basically looked like this img = ResizeImage(largeImage, 50); // shrink the image by 50%
The 'bug' was when he was passed in the thumbnail image and requesting a 300% increase, and the image was too pixelated.
I tried to explain that if you need the larger image, use the image from disk (since the images were already sized optimally for display) and the api was just for resizing downward.
Thinking I was done, the next day I was called into a large conference room with the company vice-president, two of the web-dev managers, and several of the web developers.
VP: "I received an alarming email saying you refused to fix that bug in your code. Is that correct?"
Me: "Bug? No, there is no bug. The image api is executing just as it is supposed to."
MGR1: "Uh...no it isn't. Images using *your* code is pixelated and unfit for our site and our customers."
MGR2: "Yes, I looked at your code and don't understand what the big deal is. Looks like a simple fix."
<web developers nodding their heads>
Me: "OK, I'll bite. What is the simple fix?"
<MGR2 looks over at one of the devs>
Dev1: "Well, for example, if we request an image resize of 300, and the image is only 50x50, only increase the size by 10. Maybe 15."
Me: "Wow..OK. So what if the image is, for example, 640x480?"
MGR1: "75. Maybe 80 if it's a picture of boots."
VP: "Oh yes, boots. We need good pictures of boots."
Me: "I'm not exactly sure how to break this to you, but my code doesn't do 'maybe'. I mean, you have the image from disk.
You obviously used the api to create the thumbnail, but are trying to use the thumbnail to go back to the regular size. Why not use the original image?"
<Web-Dev managers look awkwardly towards the web devs>
Dev3: "Yea, well uh...um...that would require us to create a variable or something to store the original image. The place in the code where we need the regular image, it's easier to call your method."
Me: "Um, not really. You still have to resolve the product name from the URL path. Deriving the original file name is what you are doing already. Just do the same thing in your part of the code."
Dev2: "But we'd have to change our code"
Mgr2: "I know..I know. How about if we, for example, send you 12345.jpg and request a resize greater than 100, you go to disk and look for that image?"
<VP, mgrs, and devs nod happily>
Me: "Um, no that won't work. All I see is the image stream. I have no idea what file is and the api shouldn't be guessing, going to disk or anything like that."
Dev1: "What if we pass you the file name?"
<VP, mgrs, and devs nod happily again>
Me: "No, that would break the API contract and ...uh..wait...I'm familiar with your code. How about I make the change? I'm pretty sure I'll only have to change one method"
VP: "What! No...it’s gotta be more than that. Our site is huge."
<Mgrs and devs grumble and shift around in their chairs>
Me: "I'm done talking about this. I can change your code for you or you can do it. There is no bug and I'm not changing the api because you can't use it correctly."

Later I discovered they stopped using the resize api and wrote dynamic html to 'resize' the images on the client (download the 5+ meg images, and use the length and width properties)

A friend was writing a small game. He asked me to take a look at why the FPS where horrible although he was only drawing the background each tick.

He had about 10 different images that were used to draw the background tiles. Each iteration of the game loop he would loop over all tile positions, determine which image to use for this tile, load the image from disk and create a new tile using the image, which then would be drawn and forgot.

Running a script to do some checks on a list of Git repos.

A 8 FUCKING GB VAGRANT DISK IMAGE IN IT.

i am BEYOND pissed at google.

as some of you know, i recently got android studio to run on a chromebook (you read that right), but it being a chromebook and google being a protective fucktard of their crappy operating system, i had to boot into bios every time i started it.

when i was with some friends, i started up the chromebook, and left, after telling my friends how to boot the chromebook.

ten seconds and literally one press of the esc button later, he broke the entire thing.

but that's not what that rant was about, i honestly knew it would happen eventually (although, this wasn't the best time).

so now this screen pops up.

"chrome os is damaged or missing, please insert a usb recovery drive" or something like that.

well, i'll create one. simple enough.

no wait, this is google, just your average 750 billion dollar company who cares more about responsive design then a product actually responding.

i started to create the recovery usb. of course, chrome developers thought it would be a good idea to convert the old, working fine, windows executable usb recoverer, and replace with with a fucking chrome extension.

i truly hope someone got fired.

so, after doing everything fine with the instructions, it got to the part where it wrote the os image to the usb. the writing stayed at 0%.

now this was a disk thing, writing os's and shit, so i didn't want to fuck it up. after waiting ten minutes, i pressed 'cancel.'

i tried again many times, looked things up, and frantically googled the error. i even tried the same search queries on bing, yahoo, duckduckgo and ecosia because i had the feeling google secretly had tracked me over the past 7 years and decided to not help me after all the times i said google was a fucker or something similar.

google is a fucker.

after that, i decided to fuck with it, even if it formats my fucking c drive.

i got to the same point where the writing got stuck at 0% and proceeded to fuck. i start spamming random keys, and guess what?

after i press enter, it started.

what the fuck google?
1000s of people read the article on how to make the recovery drive. why not tell them to press the goddamn enter key?

i swear there are hundreds of other people in my same situation. and all they have to do is press one fucking key???

maybe tell those people who tried to fix the shit product you sold them.

fuck you google.

The PCs in our school have a software called "Dr. Kaiser" which purpose is to prevent changes to the disk. I thought it's working like DeepFreeze for OSX devices; having a copy-on-write feature or something like that. One day a friend of mine (kinda newbie in hacking) said he wanted to create a backdoor in the system so you can login as the local administrator of the device. He replaced the "sethc.exe" in the windows directory with cmd.exe on a live distro and claimed it was working perfectly. It turned out that "Dr. Kaiser" is indeed loading the default image on startup, but doesn't verify checksums for system files (and also doesn't include the files in the default image). Long story short: You now can open a cmd with System permissions on every PC in the building.

This. Is. Stupid. It should be forbidden to sell this software 😖

So probably about a decade ago at this point I was working for free for a friend's start-up hosting company. He had rented out a high-end server in some data center and sold out virtualized chunks to clients.

This is back when you had only a few options for running virtual servers, but the market was taking off like a bat out of hell. In our case, we used User-Mode Linux (UML).

UML is essentially a kernel hack that lets you run the kernel in user space. That alone helps keep things separate or jailed. I'm pretty sure some of you can shed more light on it, but that's as I understood it at the time and I wasn't too shabby at hacking the kernel when we'd have driver issues.

Anyway, one of the ways my friend would on-board someone was to generate a new disk image file, mount it, and then chroot to that mount path. He'd basically use a stock image to do this and then wipe it out before putting it live.

I'm not sure exactly what he was doing at the time, but I got a panicked message on New Years Day saying that he had deleted everything. By everything, he had done an rm -fr /home as root on what he had thought was the root of a drive image.

It wasn't an image. It was the host server.

In the stoke of a single command, all user data was lost. We were pretty much screwed, but I have a knack for not giving up - so I spent a ton of time investigating linux file recovery.

Fun fact about UML - since the kernel runs in user space as a regular ol' process, anything it opens is attached to that process. I had noticed that while the files were "gone", I could still see disk usage. I ended up finding the images attached to their file pointers associated with each running kernel - and thankfully all customers were running at the time.

The next part was crazy, and I still think is crazy. I don't remember the command, but I had to essentially copy the image from the referenced path into a new image file, then shutdown the kernel and power it back on from the new image. We had configs all set aside, so that was easy. When it finally worked I was floored.

Rinse and repeat, I managed to drag every last missing bit out of /proc - with the only side effect being that all MySQL databases needed to be cleaned up.

Diary of an insane lead dev: day 447

pdf thumbnails that the app generates are now in S3 instead of saved on disk.

when they were on disk, we would read them from disk into a stream and then create a stream response to the client that would then render the stream in the UI (hey, I didn't write it, I just had to support it)

one of my lazy ass junior devs jumps on modifying it before I can; his solution is to retrieve the file from the cloud now, convert the stream into a base64 encoded string, and then shove that string into an already bloated viewmodel coming from the server to be rendered in the UI.

i'm like "why on earth are you doing that? did you even test the result of this and notice that rendering those thumbnails now takes 3 times as long???"

jr: "I mean, it works doesn't it?"

seriously, if the image file is already hosted on the cloud, and you can programmatically determine its URL, why wouldn't you just throw that in the src attribute in your html tag and call it a day? why would you possibly think that the extra overhead of retrieving and converting the file before passing it off to the UI in an even larger payload than before would result in a good user experience for the client???

it took me all of 30 seconds to google and find out that AWS SDK has a method to GetPreSignedURL on a private file uploaded to s3 and you can set when it expires, and the application is dead at the end of the year.

JFC. I hate trying to reason with these fuckheads by saying "you are paid for you brain, fucking USE IT" because, clearly these code monkeys do not have brains.

I just saw an ad by a viral marketing agency thisventviral.net that sell a 16GB USB stick with an os image they call Xtra-PC for 29,60.
I immediately noticed that it seemes to be a simple USB boot stick with a Linux distro with a Windows like ui and OpenOffice and other software pre installed.
They guy took out his CD drive bay an claimed that he removed the hard disk. While odd his clames about faster speeds are obviously true because microshaft windows and office are bloated pieces of shit.

So this leaves me in the odd position that a viral marketing scam selling you over priced USB sticks and an image you probably could find for free, also makes people adopt Linux instead of the bloated shit. And that with people that won't notice any of the downsides of using Linux.

Wired position, should I hate them or should I commend them for theire unintended efforts spreading Linux desktops?

I've always been kinda lazy about backups and such, thinking it wouldn't be so bad, and "I have my most important stuff on Dropbox".

Just now, for some reason one of my hard drives just stopped for a bit, and I couldn't do anything with it anymore. Luckily it went away after restarting my pc, but it scared the shit out of me, as I almost lost 500 gigs worth of music, films, documents, etc...

This made me really think about the whole backup thing, and I'm creating a disk image as I type this. The time that I spend on that will be much less then the time it'll cost to recover everything. Lesson learned ^^'

As a kid, I wanted to try new stuff. New programs, new games, new websites, new OSs. Those were the days when we had very limited and slow access to internet and cloud was still to be discovered. I had everything on my local HDD.

So one fine day I decided to try out Ubuntu on my Windows 7 Laptop.

I emptied a partition, burnt the image to a USB drive and booted from it. Installation went well.

Somehow I ended up deleting the logical partitions on my Windows machine. Not only I was not able to boot into Windows, my HDD was just one tiny partition. I cried my eyes out. That disk had everything I ever had.

PS: I recovered everything by restoring the partitions.

Last night my friend started messaging me to help her install windows 10 onto their computer. She said her and some idiot with less tech credibility then a rock tried everything they could think of. First they downloaded the windows 10 ISO from the site, good so far, then instead of burning to a disk or USB, they thought 'copy and paste' would be enough (no googling at all) obviously the image wasn't attatched correctly, so they say they spent an hour doing IDEK to get the disk to read before messaging me. I talk her through getting the ISO mounted and then it asks her for the product key, she got pissed at that and said 'They gave me the ISO for free why do I need to buy a product key'
this is why I despise my friends some days

I will never rant enough about Windows. It is so aged. I have 6TB of storage, 2 SSD of 1To and 1 HDD of 6TB

But windows doesn’t care, it will pack everything in the same disk in this damned AppData no matter where you install your softwares, making main disk full.

Wanted to build a rather big docker image, but yeah, because I guess that the guys from Docker have other things to do than caring of a 90s OS with a fancy UI, they use an emulated ext4 file system, it filled my disk, Docker is crashing because of that, letting me no other choice than removing the emulated disk.

So this is a story all about how:
I went from my brother being asked to clone the disk of old laptop to a new one. My m.2 ssd being held in with duct tape because of it and me having to run a tar command that took over 5 hours to complete.

So my bro got asked by a friends mom to help her with "PC Problems". In short the old laptop was barely useable and they ordered a new one on the reccomendations of my brother. Turns out the laptop he recomended shoud have had a 1tb hdd in it. Instead it had a 256gb m.2. Note: The old disk was 500GB.
So cloning wasnt possible. He then told me, that they also bought a regular sata ssd which was supposed to go in instead of the non present hdd. So I <-Want to emphasize on this! went to work.
Ordered a ssd in the right form factor.
Made a disk image of the old HDD.
Had to drill out the screw holding in my m.2 ssd as it was stuck.
Its now held in with a piece of kepton tape.
Wrote old disk's image on new disk.
It doesnt boot in new laptop.
Spend an evening trying to rebuild boot partitions.
Fuck it, lets install windows 10 (instead of 7) and copy all the shit over manually!
Lets buy office for 30$ on g2a as it would be a pain in the ass to explain the that its normally a subscription.
Previous rant happend.
Brought them the laptop yesterday telling them I did all the work.
I collect the ssd they ordered explaing i ordered the correct one and would take tis one for me.
Still had the 500GB img file of the disk and wanted to compress it in order to put some data back in place.
The tar command took over 5 hours to complete! I havent checked on it yet as I went to sleep.

I. Hate. Windows. Apps. UGH.

I may never be able to play FS2020 from the Xbox Game Pass again as... Its unable to install, gives a helpful 0x1 error code, and the help page link goes to a 404.

Now, I caused this myself... Partially... Er, no, fully, but I had a good reason!

I wanted to install something larger again and didn't have enough disk space. Fired up WinDirStat and there was a huge, like... 45 GB file in C:\Program Files\WindowsApps\Somedir\

Googling around, I found some people saying its a temp file so that Windows Store could reserve enough space for the app instalation... Okay, so... It got stuck, and I had no way to remove it?

Of course I didn't want to remove all apps of the windows market... So, I did something any *sane* person would never do - Took ownership of the whole WindowsApps and gave myself full control. Then I removed the file and... FS2020 never launched again.

I couldn't even uninstall it! It would give me no error either. It just lagged and then did nothing.

I tried resetting all the ACLs, tried giving ownership back to TrustedInstaller, nothing worked. Failed on some of the files, wtf?

Launching the game only ever told me there was an update in progress.

Tried booting a windows iso image and fix the ACLs from there, nope, also failed for the same bunch of files of FS2020. (Permission Denied while on a live image? Wow)

Last resort, I booted up Linux and tried removing the offending folders from there, only to find out that... Huh. The NTFS module labelled the offending folders as... broken links leading to an "unsupported reparse point". But hey, it let me remove it at least.

Since then, it no longer appeared as installed, but... Now, anytime I want to install it, it just throws an error 0x00000001 with no further details.

So yeah, I know I caused this myself, but after fiddling with the permissions and ACLs and NTFS dark magic, I feel justified in saying - Fuck you WindowsApps DRM.

tldr := Windows 10...
So I had Windows 8.1 / Linux dual boot system. And decided that, what the heck, I'll try upgrading to WinX. That went well. Surprisingly. I even used WinX for a while. Windows 10 and linux side by side, on the same disk, just different partitions. And since everything was so nice, I've decided to let Windows install some updates. After reboot, uefi linux entry is gone. What? How? Well, after update windows found 'unrecognized' partition, and, since it is urecognized, it must be unused. So it helpfully fucked it up. That was linux uefi partition (yes, I kept them separate).
Long story short, windows8.1 back from original image, side by side with linux. Lesson learned, gonna ispect each windows update twice before installing. And not gonna touch WX even with a 10-foot stick!

I remember the day I used Linux to enforce size quotas on user directories oh what a day
I was surrounded by horrible monsters wearing manho suits that made them appear superficially human... though the sounds screeching forth from their many toothed mouths in whining jarring tones would suggest otherwise and I used this wonderful feature : you can call most of the file systems commands on files !

did a dd to create a disk image specified to the correct size made an fs inside and mounted it straight into the home directory adding entries to the fstab to auto mount and setting the io permissions
It was so wonderful and the little bastards refused to use the server !

Yesterday I bought a thumb drive for installing Windows 10. I've also tried booting the Windows 10 installation media from a partition with grub, and adding the storage drivers to the install.wim image, but the drivers don't install correctly and I don't get it to work. I'm on Arch Linux and a laptop.
I spent 4+ hours on that. uefi-ntfs.img, Windows 10, also tried Windows 7, gparted, cp, bla, bla, bla.
On attempt n12903813280, I open again gparted.
/dev/sdb: unrecognized disk label
Turns out somehow I damaged the thumb drive after so many writing. In just a few hours.
Dude I'm literally stuck on Linux. Get me out of here. I want to be normal and play Valorant.

I have this system that receives an image on Base64 or the URL (in that case the system makes an HTTP request and saves re response to disk). It works beautiful when I run the tests, it doesn't work at all in production (all the resulting files are corrupted). I don't know how to start to debug it so I'm going to bed and let my future self to resolve the issue.

Error: Disk image full.
...
Not good on a production SMB server. Wasted 2 hours tracking the fault down....

Turns out the boss thought it would be a good idea to install syncing software as remote backup without telling anyone...

It wasn't remote :(

!dev (kinda)

Warning: Might contain (be) stupid rambling.

So I got my new toy and want to play around with it. Just in case I have to return it I first want to make a full disk backup, so I try to boot clonezilla. I press the power button and mash F2, F8, F9 - and it boots straight into the windows setup. Nope, not what I wanted. Try again. And again. Eventually I look it up and apparently I have to hammer the ESC key to get where I want to. Alright, now it works. Boot from USB. Failed. Try again. Failed. Check the BIOS, disable secure boot, reboot. I need to type 4 digits to confirm disabling secure boot. Alright. Reboot, try again, failed. Secure boot is on again. Wtf? After some more infuriating tries I see that NumLock is disabled. AAAARGH. BIOS: Enable NumLock on boot, disable secure boot, enable legacy boot. Input the 4 digits - works! Try to boot from USB: Failed! Grab another USB stick, did the clonezilla image, try again: Finally! It! Works!

Format disk, install Qubes OS. Success!

Who asked for RedDatabase and RedXpert? You guessed it - nobody 😑 It's a buggy Firebird and DBeaver domestic knock-off!

My student was assigned with making Flask app by "simple" requirements. But guess what? We can't figure out hecking RedDatabase?! Figures out that they sent incompatible *.fdb database file, on which we wasted entire 3 hours troubleshooting obscure error, while clean database doesn't cause any trouble.

Last error that completely drained us is following:
"""
Reason: unsupported on-disk structure for file /var/rdb/test.fdb; found 12.3, support 12.2; IProvider::attachDatabase failed when loading mapping cache [SQLState:HY000, ISC error code:335544379]
"""

So now, he basically recreates database by scheme on image. What also shady seems to me is that application also has to deployed on virtual OS which he can bring on USB stick or by cloud later.

I have the creeping feeling that my laptop is going to kick the bucket (in some way or another) soon. I've had two laptops die on me, both times it was something breaking inside the HDDs and I ended up loosing almost all of my data in both cases.

This time I want to be prepared. How do you guys back up your stuff? Is there a way to take a complete image of all my files? (for windows) or should I manually sift through my files and save them in an organized manner on an external disk?

I open Photoshop, I open an image, I start editing colors. I think to myself "I need to change units to pixels instead of inches". I open the "Preferences - Units" menu. I approach the mouse and click on the selection box for units.... My screens go crazy suddenly and I get a BSOD...
The computer reboots, refuses to repair, complains it can't write on the disk. I launch UBCD, start TestDisk, it tells me my MFT and the mirror MFT are both completely messed up and the partition contents as well... Wow wow... What the...?!
Complete reinstall.
Thank you Intel GFX system driver.
