So a few days ago I felt pretty h*ckin professional.

I'm an intern and my job was to get the last 2003 server off the racks (It's a government job, so it's a wonder we only have one 2003 server left). The problem being that the service running on that server cannot just be placed on a new OS. It's some custom engineering document server that was built in 2003 on a 1995 tech stack and it had been abandoned for so long that it was apparently lost to time with no hope of recovery.

"Please redesign the system. Use a modern tech stack. Have at it, she's your project, do as you wish."

Music to my ears.

First challenge is getting the data off the old server. It's a 1995 .mdb file, so the most recent version of Access that would be able to open it is 2010.

Option two: There's an "export" button that literally just vomits all 16,644 records into a tab-delimited text file. Since this option didn't require scavenging up an old version of Access, I wrote a Python script to just read the export file.

And something like 30% of the records were invalid. Why? Well, one of the fields allowed for newline characters. This was an issue because records were separated by newline. So any record with a field containing newline became invalid.

Although, this did not stop me. Not even close. I figured it out and fixed it in about 10 minutes. All records read into the program without issue.

Next for designing the database. My stack is MySQL and NodeJS, which my supervisors approved of. There was a lot of data that looked like it would fit into an integer, but one or two odd records would have something like "1050b" which mean that just a few items prevented me from having as slick of a database design as I wanted. I designed the tables, about 18 columns per record, mostly varchar(64).

Next challenge was putting the exported data into the database. At first I thought of doing it record by record from my python script. Connect to the MySQL server and just iterate over all the data I had. But what I ended up actually doing was generating a .sql file and running that on the server. This took a few tries thanks to a lot of inconsistencies in the data, but eventually, I got all 16k records in the new database and I had never been so happy.

The next two hours were very productive, designing a front end which was very clean. I had just enough time to design a rough prototype that works totally off ajax requests. I want to keep it that way so that other services can contact this data, as it may be useful to have an engineering data API.

Anyways, that was my win story of the week. I was handed a challenge; an old, decaying server full of important data, and despite the hitches one might expect from archaic data, I was able to rescue every byte. I will probably be presenting my prototype to the higher ups in Engineering sometime this week.

Happy Algo!

Customer care guys are stupid
Me : yeah, OS crashed. It keeps getting into bios setup saying there's no hard drive detected on this system and no recovery file found as well, what do ?
Him : "well sir, your OS has been corrupted and now you have to buy new licensed one, if you can just give me your location I can help you locate out nearest service centre which will help you install a new licensed instantly"
Me : *WHAT THE ACTUAL TRIPLE FUCK* atleast try to understand the problem first.
Him : No need sir, I already come across this problem and now you have to pay, as I was saying *beep*
*I smashed the phone*
After that I fixed it myself
These low level shit licking faggots need to get themselves fucked in the ass by horses and then apply the same conversation when the intercourse begins with the horse.
Also, if I could be placed in the same customer care cell, I would do better.
So wk62 too I guess

So my friend was in a hurry when she was setting up the passocde for her phone and later she forgot the code.
So she takes it to the service center.

SC guy: Ma'am we have to do bla bla bla. And you will lose your data. It will cost you around $10.

She just came back and later gave me the phone.
*unlocks bootloader *
*flashes a custom recovery*
*delete passcode file*
Phone is now unlocked with all the data intact.

PS: I got a small treat at McDonald's. 😋

'Sup mates.
First rant...
So Here's a story of how I severely messed up my mental health trying to fit in university.

But the bonus: Found my passion.
Her we go,

Went to university thinking it'll be awesome to learn new stuff.
1st sem was pure shock - Programming was taught at the speed of V2 rockets.
Everything was centred around marks.

Wanted to get a good run in 2nd sem, started to learn Vector design, but RIP- Hospitalized for Staph infection, missed the whole sem and was in recovery for 3 months.
So asked uni for financial assistance as I had to re-register the courses the next semester. They flat out refused, not even in this serious of a case.

So, time to register courses for third semester, turns out most of the 2nd year courses are full, I had to take 3rd year courses like:
Social and Informational Networks
Human Computer Interaction
Image processing
And
Parallel and Distributed Computing (They had no prerequisites listed, for the cucks they are: BIG MISTAKE)
Turns out the first day of classes that I attend, the Image proc. teacher tells me that it's gonna be difficult for 2nd years so I drop it, as the PDC prof. also seconds that advice.

Time travel 2 months in: The PDC prof is a bitch, doesn't upload any notes at all and teaches like she's on Velocity-9 while treating this subject like a competition on who learns the most rather than helping everyone understand.
Doesn't let students talk to each other in lab even if one wants to clear their friend's doubt, "Do it on your own!" What the actual fuck?

Time for term end exams and project submission: Me and 3 seniors implement a Distributed File System in python and show it to her, she looks satisfied.
Project Results: Everyone else got 95/100
I got 76.
She's so prejudiced that she thinks that 2nd years must have been freeloaders while I put my ass on turbo for the whole sem, learning to code while tackling advanced concepts to the point that I hated to code.

I passed the course with a D grade.
People with zero consideration for others get absolutely zero respect from me.
Well it's safe to say that I went Nuclear(heh.. pun..) at this point, Mentally I was in such a bad place that I broke down.... Went into depression but didn't realise it.

But,
I met a senior in my HCI class that I did a project with, after which I discovered we had lots of similar interests.
We became good friends and started collaborating on design projects and video game prototyping.

Enter the 4th sem and holy mother of God did I got some bad bad profs....
Then it hit me
I have been here for two years, put myself through the meat grinder and tore my soul into shreds.
This Is Not Me
This Wont Be The End Of Me
I called up my sister in London and just vented all my emotions in front of her.
Relief.
Been a long time since I felt that.
I decided to go for what I truly feel passionate about: Game Design

So I am now trying to apply for Universities which have specialised courses for game design.

I've got my groove again, learnt to live again.
Learning C# now.
:)
It's been a long hello, and If you've reached till here somehow, then damn, you the MVP.
Peace.

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.

*edits file on remote server*
WanBLowS: naah you can't 😈
*le wild BSOD appears for the over 9000-th time*

... Yeah. Windows, great job. Who needs system integrity when they're working on remote servers anyway, right?!

And to top it all off, le reboot mentions that they're working on fucking "features" again. That's what you needed to BSOD for?! For a goddamn motherfucking feature?!! Fucking piece of shit.

At least when I opened vim on that server again, it's saved everything neatly in the .swp files, ready for recovery. Now that's neat, isn't it? Microsoft, the Linux community has already moved on to nvim in terms of development, but maybe, just maybe, you can learn a thing or two from our "legacy software", vim.

As for me, maybe it's time to take out my Arch laptop again. At least that won't crap out on me because the sun and the stars are in a position that the OS doesn't like, or something stupid like that. FUCK YOU MICROSHIT!!!

Last week I was erasing a 2Gb USB thumb while copying some really important shit to my backup disk. I look at the terminal and see it's taking a lot of time to did zeroes on dev/sdb.
Then I realized that dev/sdb is the backups drive and I just erased the firsts sectors of my only fucking backup.
It's ok, I said, let's see what can TestDisk do for me. And it only could find an empty sad partition that had useless shit on it. Whdd couldn't even find the drive. Cat and dd vomited 160Gb of nothing to a file that couldn't be read. I was lost, because I failed doing something I'm really good at. And I did it because I was to stupid to check fstab...
It's the very first time I couldn't recover data, so I'm thinking about delete "Data recovery" from my resume skills and put "Data cleaning. Really effective. I can send you 160Gb of pure horse shit to prove it" instead.

DO !!!NOT!!!!! USE 'X' AND 'P' TO 'CUT AND PASTE' A LOT OF LINES ACROSS FILES IN VIM!!! HOLY SHIT I JUST PWNED MYSELF SO HARD I LOST SO MUCH CODE HOLY FUCK IT'S NOT EVEN FUNNY! WHERE DID AT ALL GO YOU ASK, WHY THE FUCKING REGISTER, OK LET'S CHECK THE REGISTER, COOL THERE IT IS, BUT WAIT, THERE'S ONLY LIKE 20% OF IT BECAUSE WE CUT A SHIT LOAD OF LINES AT ONCE, AND THE REGISTER OVERFILLED.... Ok let's calm down, doesn't Vim have a recovery option? Yes it does, but WAIT A FUCKING MINUTE, MY CHANGES ARE NOT IN THE SWAP FILE BECAUSE IT'S NOT LIKE VIM CRASHED OR ANYTHING, MY DUMB-FUCK-ASS WILLFULLY WROTE THE CHANGES WHEN I SWITCHED OVER TO THE NEW FILE, AND NOW, WELL THAT'S IT, YOU'RE DEAD KIDDO, YOU WROTE THE CHANGES TO DISK, NOTHING YOU CAN DO, AND I AM SO SCREWED I SPECIFICALLY MADE A DEVRANT ACCOUNT TO MAKE SURE NO ONE ELSE PWNS HIMSELF AS HARD AS I JUST DID HOLY FUCK

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?????)

nearly cried.

I had been working on this file for the last 4 or so hours.

And accidentally deleted it with NerdTree (mdy).

300 loc. poof.

scoured internet for recovery procedure.

and.......
... to no avail. just about to give up.

here comes the climax: .....

It was stillllll...... in the NEOVIM. BUFFER.
vim got my back.

praise you vim lord.

#vim_pope

Stopid mf fat fingers, worked 2 weeks building a design system and 2 hours ago I accidentally shift deleted the scss folder and lost every fcking file, no git, no backup, no nada,guess what, tried to recover the files with 2 Permanently deleted file recovery softwares and from fcking 20 files, 17 were corrupted and weren’t readable, I and my designer friend use a folder sync app, the fcking app synced the delete and she lost the files aswell, fooockiinggg shieeeet, to my don’t know how where luck I managed to recover the copiled javascript chunck from my vue app that had the css styles embeded in the file, you know where I found the js file? iN ThE fcking cache of google chrome. Today I almost broke down to tears, but nonetheless it was a reeee moment for me.

So, idiot me decided it would be a good idea to never get around to configuring my UPS to gracefully shutdown my server after a powercut lasting more than x duration...

Long story short, we had a powercut that lasted 4 minutes or so longer than the battery in the UPS could keep the server up for...

UPS died, server went pew, and after rebooting itself once the power came back on, my raid array wouldn’t mount anymore...

After Googling around, it seemed like running e2fsck would solve the problem.

Didn’t seem to do the trick... and tired me at 3am decided it would be a good idea to poke around.

Pretty sure I ran a command wrong, or two, because now I can’t even mount the fricken array in read only, and fsck complains with a shit ton errors...

Been researching for hours, and no dice...

Test Disk shows the ext4 partition, but fails to list any files...

I may have destroyed the tables or something... I’m a noob at this point.

I’m able to access files with the RStudio tool, however this doesn’t help with file names and directory structure 😭

Is it all over for my 5 years worth of photos and other bits and pieces that I don’t have any backups of ? 😂😭😭

If any of y’all are pros with data recovery and can help a fellow boi out, I’d be more than happy to pay for ya time !

Accidentally rm -rf a git repo, one of the branch still not pushed to remote yet. I managed to use file recovery software to recover the .git folder, any idea what to do next?

Update on my previous rant -

Mac restart after upgrade got stuck due to a fucking corrupted kext file, had to switch between recovery and safe/verbose mode to isolate that bastard, move him out of the folder and then do a clean restart.. Then, after 7 hours, it said 15 minutes remaining to complete installation...

Finally, it came up fine, doing healthy :)

Dear Mac, You, Sir, gave me a scare during a restart and are becoming like Windows (note: bsod) :(

!(!(!(!(!(!(!(!rant)))))))
My new HTC smartphone hates me.
First it started to shut down all of the sudden yesterday night, when I was solving quadratic equations on my laptop.
I thought that it might be due to low battery. So I have restarted it. After putting itself into a bootloop for 4 start sequences, it was able to fully start to the page where it told me to enter the security pin to decrypt my files. I also had 30 attempts left. Like a ransomware.

I was like "tf I didn't set anything up".
So I decided to use my first attempt as I had 30 attempts left.
I entered the pin (I can swear that it's correct) and it told me that it has to wipe the /data partition.

I did that. I pressed that button. After waiting for 30 minutes I gave up and rebooted into the bootloader.
Bootloader -> Download Mode -> wipe /data (stock rom + stock recovery btw.)

Some error with "e: mount /cache failed[...]e: mount /data failed"
So, I tried using the adb sideload - no success.
Fastbooted into RUU Mode - HTC keeps rebooting itself into the RUU Mode - no success

Tried to flash the firmware and twrp recovery from Download mode - no success
Then I tried to flash all these things from the sd card - no success

Searched for revolutionary (I know this from my old HTC sensation device).
It wasn't big of any help.

Then someone on xda recommended htcDev (htc's <b>developer-friendly</b> lol site)
I followed every step. Everything seemed to be okay.
I got to the last step.
I needed to get my encrypted token by entering "fastboot oem get_identifier_token" to be able to submit it to HTC, and after they would send me an e-Mail with an .bin file that would let me unlock the bootloader to be able to flash my way through all this headache giving fucking piece of dog shit!

But since I can't back to the phone settings to select the bootloader activation box that would let me get my token... but nah.

Living on the edge!

One or two years ago I managed to deploy a DDL change directly on the production server. As I knew there was a backup job which will run every day at noon and at midnight. So I run my script some minutes after noon. So far so good. But somehow I tested it badly in my test environment and the UI of the application throws error after error now in production.

Well, just revert the db to the latest recovery point with the backup, I thought.

It became clear then after a couple of minutes of searching the backup folder for the db backup that there was no such file. The youngest backup file was 3 years old.

Now what happened: The backup script had a switch "simulate=true" and then simulated a successful backup on each run. Therefore the monitoring system got no alerts for not correctly executing those jobs correctly. Then the monitoring job which should do the backupfolder surveillance stuck with green, because there was a valid backup file inside. But it did not check for a specific creation date.

Now this database is the one we need for doing our daily business and is really crucial. Therefore It was easier to emergencyfix the application than doing a rollback of the db 🙄

Well, not really a data loss story, but close to one.

At one point, my laptop's hard drive went down. Turns out, windows had written some garbage data to the mft, and fucked up the file structure. Luckily i was able to restore a big chunk of the data using recuva. I cleaned the disk after saving the most important files, cleaned the disk, reinstalled windows. All good so far. I put the laptop's drive and my recovery disk into my desktop to put back the files. During the install in forced me to make an account, which I wanted to delete. So I ran "rmdir /users /s" and went to grab a cup of coffee. Turns out, cmd was pointed at my recovery disk instead of my laptop disk. My whole backup wiped.

Whenever I have my mac crash and corrupt its OS, I just get a backup harddrive and it copies itself FLAWESSLY. I have all my programs, settings, settings in programs and files.

When Windows crashes, and I use the recovery tool, I LOOSE EVERYTHING. The only thing I get to keep are my files, and they most of the time have permission issues after a restore.

Windows is like the toddler that stares out to void of existance and can't do anything but drool on their shirt, while its parents say he's highly gifted.

Fuck me we're able to choose between only a few OS'es that my clients know and allow me to work on but things like this just make me want to go be a chicken farmer or something.

So last night I ran out of space on my root partition, apparently 30GB isn't enough for `/` besides `/home` and `/data` because both `/var` and `/usr` used around 14GB each so I decided to create partitions for them, had 500GB unallocated disk space on my SSD for if I wanted to install windows on my machine besides Arch Linux.

I edited the fstab file and sure enough, the partitions were mounted on boot, everything went fine. Then U realised the data wasn't actually removed from the first partition so I decided to mount the drive again and remove the files, the system still worked fine.

Untill I rebooted. Apparently the bit scripts require files in the`/usr` folder which wasn't mounted at boot, but right after. F*ck, system won't boot and now I'm in a recovery shell in busybox. After googling and reading the arch wiki I noticed a small message saying what you should do if you want to have `/usr` on another partition. I didn't do any of that.

After a couple of hours and a lot of reboots and chroots from a live USB to the broken installation it was fixed without losing any data! I did learn to read the manual or wiki to see any specifics when using more partitions. 😂

Ended up dong an internship for my school (not really internship, more along the lines of formal volunteering, but whatever) helping set up laptops for a statewide standardized assessment.

I made a program to log the machine's identifying info (Serial, MAC addresses, etc), renames it, joins it to the school's Active Directory, and takes notes on machines, which gets dumped into a csv file.

Made the classic rookie mistake of backing things up occasionally, but not often enough. Accidentally nuked the flash drive with the data on it, and spent a good while learning data recovery and how grep works.

Lesson Learned? Back up frequently and back up everything

Okay new Rant
INSERT TRIGGER WARNING HERE

OSX still sucks I have been using the bloody darn thing for last 8 months still I found things that are obnoxiously trivial missing.
Latest incident I was trying to plug in my android phone(soft bricked) in recovery mode and I had to push a file with ADB (i save this mutherfuker for another day). So back to the original topic now I plug it in and but turns out it doesn't recognize my device now as a preliminary check I decide to check my USB cable and my DONGLE both seem to be working fine now I try rebooting back into recovery. Now after scrapping the internet for a few hours I find that this problem is caused because sometimes due to a recurrent bug in OSX the operating system sometimes fails to recognize the difference in between directories "Adam"(just an example) and "adam" which in turn can interfere with some of the flags used while checking if a device might be connected.

I mean this is fucked why the fuck can you not simply use your device as an external storage that would have made the process easier by a fucking lot.

I think the people at Apple are going the destroy a UNIX powerhouse just to make their OS more CUPCAKE friendly.
And all of this is in addition to the problems with AFS.

I just wish I had not bought mac for development

So my friends USB drive suddenly doesn't work. It shows up in Windows' device manager (with no exclamation sign) but not in My Computer or even Disk Management (So I can't partition it) Reinstalling drivers doesn't work either. When trying to mount it in Linux, Linux complains that it can't see the drive. fsck and gparted don't read it either, but it shows up in lsblk. Dmesg complains it can't read the partition table (error -110). Any of you guys have bright ideas? Nothing like this has shown up in SO before so I've asked in both here and SO. Any ideas?

This happened to me sometime back.

I want to try out a WordPress plugin in my local machine before installing on a production server. It is an Ubuntu machine. Downloaded and installed Xampp, then setup WordPress with MySQL. Now tried uploading the plugin zip file, it throws some permission error, asking to fix permissions or use FTP. I thought of just chmod 777 recursively for the WordPress directory to fix this easily.

Ran the command, looks like it is hung. Terminated using Ctrl+C and then ran the same command. Again it is taking much time. It should not take so much time to recursively change the permission of just a WordPress directory. Thought something was wrong. Before I realized the damage is already done.

Looks like I ran the command

sudo chmod -R 777 /

instead of

sudo chmod -R 777 ./

Fuck, I missed a dot in the command and it is changing permissions of everything in my machine. Saw the System monitor, CPU usage spiked to 100%. I can't close or open any program. Force shutdown the machine using the power key. It didn't boot again. Recovery mode didn't help. Looks like there is no easy way to restore back from this damage. Most of the files I need are backed up in the cloud, still, need a few more personal files so that I can format and reinstall Ubuntu. Realised I have Windows in dual booting. Boot into Windows and used some ext4 reader to recover the files, formatted and reinstalled the OS. Took a few hours to get back to my previous setup.

Lesson Learned: Don't use sudo unnecessarily.
Double check the command while executing.
Running a wrong command with root permission can fuckup your entire machine.

I had that installation of windows 3 to 4 years now.
I'm using a third party software for backup so everyday at 23:00 the backup service starts. The image is stored on a second HDD.
First i want to point out that i set up the windows maintenance around that time too. So any updates should occur then and i remember finding my PC at login screen couple of times meaning a restart had taken place.
Everything was fine all this time.
Couple of days ago i returned home late around 2 am to find a blue screen saying that the computer did not boot property the last time. Had two options, just restart or try to fix.
Of course i will fix it, come on.
Everything failed. Everything. Even safe mode won't boot.
Who cares i have the back up system image. Boot from the bootable usb stick and restore. Well nothing is happening. It's just freezing at 5%. Cancel. Try again. Cancel. Verify the image. Success! Try again! Nothing.
Damn. Im really tired, off to bed.
Woke up tried fixing and restore but to no avail.
Fuck it i will just install Windows fresh. I was set up after an hour or so installed the necessary drivers and such. Let's see that image of any file i want to get back.
Image is corrupted. What the fuck? How? Damn it. Mount and recovery also failed.

That's it. I did not lose any important files. I save everything on a different drive and also the backup.
But I'm wondering what had gone wrong.
My guess windows rebooted when the backup was running. If that's the case shouldn't be a check if such service is running?
