Have you ever felt that you're being overrated by your employer ?
For our front end projects we use Cloud9 IDE
Now the business have around 100k+ files.
So Cloud9 is becoming slower and slower with every new project created.
So I was tasked to build a code editor where a new instance of that code editor will be created per project ( so, the new editor doesn't need to handle a huge file tree), so I "git clone" ACE editor and add to it GoldenLayout.js , FancyTree.js and some other plugins.
Now they think I'm a genius, and I'm like ... Eh? Should I tell them.. ? Will it backfire later ?
I kinda like the feeling.
What's the best thing to do in this case?3 -
And this, ladies and gentlemen, is why you need properly tested backups!
TL;DR: user blocked on old gitlab instance cascade deleted all projects the user was set as owner.
So, at my customer, collegue "j" reviews gitlab users and groups, notices an user who left the organisation
"j" : ill block this user
> "j" blocks user
> minutes pass away, working, minding our own business
> a wild team devops leader "k" appears
k: where are all the git projects?
> waitwut?.jpg
> k: yeah all git projects where user was owner of, are deleted
> j.feeling.despair() ; me.feeling.despair();
> checks logs on server, notices it cascade deletes all projects to that user
> lmgt log line
> is a bugreport reported 3(!) years ago
> gitlab hasnt been updated since 3 years
> gitlab system owner is not present, backup contact doesnt know shit about it
> i investigate further, no daily backup cron tasks, no backup has been made whatsoever.
> only 'backups' are on file system level, trying to restore those
> gitlab requires restore of postgres db
> backup does not contain postgres since the backup product does not support that (wtf???)
> fubar.scene
> filesystem restore finished...
> backup product did not back up all files from git tree, like none of refs were stored since the product cannot handle such filenames .. Git repo's completely broken
Fuck my life6 -
Two years ago, I developed an security app for Android as a school project. I didn't like teamwork at school (you know, you do all the work and everyone else is getting the same grade you receive, specially if you are the nerd of the class), actually I hated it, so I made it alone.
Its name was "Alex" and was a simple "panic button". You can configure two emergency emails and phone numbers (contacts only, not police) and, if you're in danger, you just have to press the button and the app is gonna send two messages/emails to your contacts: the first one, to tell where are you (GPS, only the name of the place) and that you're in problems. The second one with an audio/photo file of the situation.
Sounds like a great app, and I tested it few times. The reason I didn't continue with this is that I got my first job and I had not time, and that, tree or four months later, the government (of the city) launched a similar app. Less sophisticated, but I think it's still useful: "No estoy sola"(I'm not alone). I haven't tested it cause I don't trust on the authorities, I'd preffer to send my location to a friend through messenger app instead.
I don't know if I should re-work this app (I didn't released it, I just have the beta) or work on something else. I'm afraid that, if I release it, someone could die or get kidnapped because of a bug or something going wrong with the app :c What do you think?5 -
Storytime!
I got a ticket near the end of the day, asking to install a printer on a computer. The branch in question was in a different time zone (I'm in US-Pacific [GMT-07] and the computer was in US-Eastern [GMT-04]). I figured I wouldn't worry about it; after all, I had other tickets to work on that were much higher priority.
The next day I come into work and immediately get a message from one of my East Coast coworkers, telling me that this branch is calling and asking how the printer is coming. I told him to tell them I would call them a bit later. I do a couple of easy jobs and then begrudgingly call the branch. I listen to the phone tree that they have (which requires two button presses instead of one in order to speak with someone) and finally get in contact with a person... only to have the call disconnect.
I call back and ask for the person who called in the ticket and then followed up, who had apparently gone to lunch. I informed the person that I was just going to install the printer and it would be good to go. This would be fine... up until she mentioned she needed scanning functionality.
Now I wasn't sure if the driver we have in AD is set up with the scan functionality, so I said okay, but that meant I would have to get the driver from the website. The connection to our branches are about 1Mbps, so even downloading Java updates (60-ish MB) take about 5-10 minutes on a good day. The file for this printer was about 700MB (thanks HP). So I went and did other stuff while that downloaded.
I come back after it finished and started the install process. Right away it asks to re-seat the USB cable. So I call the branch. The call disconnects. I call again. It disconnects. I call one more time, and finally get the person who called the ticket in. I instruct him to re-seat the cable. He does. The driver starts doing its thing. I tell him I'll call back if I run into any issues and we hang up.
The driver goes through the install process for about 20 minutes, stops at 99%, then fails. I want to restart the computer, just in case there's a conflict somewhere, but that would require calling the store again, so I put it off.
About an hour later I get a message from another East Coast coworker, telling me the branch is calling about the printer again. I was in the middle of another call and said I would call back later. I do. It disconnects. I call again, and get the person who called the ticket in again. I tell him I want to restart the computer, but wasn't sure if it was okay. He checks with the people using it, who says it's okay, so I reboot. I hang up.
Once the computer comes back up I start the install process again. It asks to re-seat the cable. Fuck. I don't want to call the store again, so I open notepad and say "Please take out the printer's USB connection from the back of the computer."
Three. Fucking. People. Saw it. They moved the window and one even tried to close it, but they didn't re-seat the cable. I opened another window, telling them to call me at my number. They didn't. I called them. Got disconnected. I called them again, finally got someone, told them to re-seat the printer cable again. They do, thank god.
I say thank you and hang up. Continue the installer. It stops at 99% again and fails. I reboot the computer; screw it, I'm just going to install the driver from Active Directory. Check Devices and Printers. It's installed successfully. Hallelujah!
I get the printer set up for the various programs they use and print a test page. I call them one last time; their phone system sounding like they were connected via an underwater line connected by tin cans. I get someone.
$me: Hi, I want to know if the printer has printed something.
$them (garbled): -et me shee... yesh, it -rint-d a *beezelborp*.
$me: Perfect, I'm going to close this ticket! Thanks, goodbye! *hangs up*
tl;dr - I hate printers -
(Dev)Life in the past 12 hours
Oh boy have the last 12 hours been a roller coaster ride for me. Noob me decided to "compile" AoSP for my device to get a taste of how custom ROMs are built from source. Overall it was fun but the errors were a very good excercise for googling, SO. Couple stuff I learnt ( possibly useful for anyone who comes here )
* The shebang line ( #!/usr/bin/env python ) on my system translated to Python 3.7 environment instead of the expected Python 2.7. Best solution I think to avoid confusion is to create a python 2.7 environment and source it.
* Get your trees right. A jar file called WfdCommon.jar ( apparently known as wifi-display common ) was the cause of several hours of hunting the fault. My vendor tree somehow didn't have this file so dex2oat was borking out like mad. I'm still amazed how I figured this one out almost by myself. ( Basically I had to check every file included in the boot class path, and find the odd one )
* I wasted a lot of time in finding the right files to change version numbers and all. Maybe I didn't search XDA properly for a guide ?
Overall it was a fun experience. Also if anyone's experienced in this area could you share resources to learn more about custom ROM development? Specifically on the tweaking part where you mix features from different ROMs to make a great ROM ( like AoSP extended or Pixel Experience ). All I could find were on the zips and not on sources.7 -
Part two of: a day off an iOS developer life:
1. App crashed and stack trace gives no info in which file it happened, I have a generic table view cell that is used in so many places and Xcode just wrote: xcell does not support key value.
2. Mac freezing when Xcode is creating IPA file thanks to a new feature in Xcode 9 (Mac freezing is the new feature, even mouse pointer doesn't move -.-)
3. Let's check the value of this class property, Xcode: fuck off and either print it in console (after hitting a break point) or expand that shitty tree at the bottom to reach your class property!
An advice: never click jump to definition when Xcode is indexing, it will either freezing Xcode or crash it.

just found out a vulnerability in the website of the 3rd best high school in my country.
TL;DR: they had burried in some folders a c99 shell.
i am a begginer html/sql/php guy and really was looking into learning a bit here and there about them because i really like problem solving and found out ctfs mainly focus on this part of programming. i am a c++ programmer which does school contest like programming problems and i really enjoy them.
now back on topic.
with this urge to learn more web programming i said to myself what other method to learn better than real life sites! so i did just that. i first checked my school site. right click. inspect element. it seemed the site was made with wordpress. after looking more into the html code for the site i concluded all the images and files i could see on the site were from a folder on the server named 'wp-content/uploads'. i checked the folder. and here it got interesting. i did a get request on the site. saw the details. then i checked the site. bingo! there are 3 folders named '2017', '2018', '2019'. i said to myself: 'i am god.'
i could literally see all the announcements they have made from 2017-2019. and they were organised by month!!! my curiosity to see everything got me to the final destination.
with this adrenaline i thought about another site. in my city i have the 3rd most acclaimed high school in the country. what about checking their security?
so i typed the web address. looked around. again, right click, inspect element and looked around the source code. this time i was more lucky. this site is handmade!!! i was soooo happy because with my school's site i was restricted with what they have made with wordpress and i don't have much experience with it.
amd so i began looking what request the site made for the logos and other links. it seemed all the other links on the site were with this format: www.site.com/index.php?home. and i was very confused and still am. is this referencing some part of the site in the index.php file? is the whole site written inside the index.php file and with the question mark you just get to a part of the site? i don't really get it.
so nothing interesting inside the networking tab, just some stylesheets for the site's design i guess. i switched to the debugger tab and holy moly!! yes, it had that tree structure. very familiar. just like a project inside codeblocks or something familiar with it. and then it clicked me. there was the index.php file! and there was another folder from which i've seen nothing from the network tab. i finally got a lead!! i returned in the network tab, did a request to see the spgm folder and boooom a site appeared and i saw some files and folders from 2016. there was a spgm.js file and a spgm.php file. there was a contrib, flavors, gal and lang folders. then it once again clicked me! the lang folder was las updated this year in february. so i checked the folder and there were some files named lang with the extension named after their language and these files were last updated in 2016 so i left them alone. but there was this little snitch, this little 650K file named after the name of the school's site with the extension '.php' aaaaand it was last modified this year!!!! i was so excited! i thought i found a secret and different design of the site or something completely else! i clicked it and at first i was scared there was this black/red theme going on my screen and something was a little odd. there were no school announcements or event, nononoooo. this was still a tree structured view. at the top of the site it's written '!c99Shell v. 1.0...'
this was a big nono. i saw i could acces all kinds of folders. then i switched to the normal school website and tried to access a folder i have seen named userfiles and got a 403 forbidden error. wopsie. i then switched to the c99 shell website and tried to access the userfiles folder and my boy showed all of its contents. it was nakeeed naked. like very naked. and in the userfiles folder there were all, but i mean ALL files and folders they have on the server. there were a file with the salary of each job available in the school. some announcements. there was a list with all the students which failed classes. there were folders for contests they held. it was an absolute mess and i couldn't believe it.
i stopped and looked at the monitor. what have i done? just to learn some web programming i just leaked the server of the 3rd most famous high school in my country. image a black hat which would have seriously caused more damage. currently i am writing an email to the school to updrage their security because it is reaaaaly bad.
and the journy didn't end here. i 'hacked' the site 2 days ago and just now i thought about writing an email to the school. after i found i could access the WHOLE server i searched for the real attacker so if you want to knkw how this one went let me know in the comments.
sorry for the long post, but couldn't held it anymore13 -
Why, in 2023, do we still have a path length limit in Windows?
I know it's not that trivial finding a good soution, but at least if I managed to get a .zip which I can't extract in that directory because of a few files with a too long file name, let me know in advance (and not during the extraction) and maybe (amazing idea) let me know how many steps I have to go back in the directories tree to make it work…12 -

So I see posts about an interview question/challenge of inverting a binary tree. I don't use trees very often (mainly file related or parsing server nodes), but I thought I would learn how to do this.
I saw a page that started talking about different ways to invert enough to understand that one type of inversion is swapping left and right nodes. So I stopped before they showed how.
Then I created a test program that has a tree structure and also can display a tree before and after modification. This was kind of fun.
So then I wrote the inversion function. It was less than 10 lines of code. Wtf? I thought it would be harder than this.
Then I started wondering where trees were used. So today I have been learning how they are used and why I might need one to solve a problem. One use I intuited was parsing regex or a language. Apparently it is useful there.
What I am learning is that a lot of these interview questions are really test to see if you can comprehend instructions when stressed. Or you will ask questions to clarify the task. It doesn't necessarily test your ability to solve hard problems.
One thing that perplexes me. If inverting a tree is swapping nodes left<->right, then why not leave data in place and just swap roles in the functions. Maybe I completely misunderstood what inversion means or why it would be done. I guess if this is not inverting I have the structure to try other methods now.2 -

I prefer VSCode over visual studio for a ton of tiny conveniences. Some git operations can really only be done conveniently by switching rapidly between the command line and the big scrollable list of diffs. The currently open file is automatically focused in the tree, not by explicit user command. Ctrl+Tab shows the last viewed section of files and not their name, so I can find an arbitrary point in my jump chain. If I open the diff for a newly added file it's possible that I want to edit the file, but it's also possible that I didn't notice that it's newly added. Painting the whole background green doesn't hinder the first scenario nearly as much as it solves the second, in contrast to VS not showing any changes, which just has me confused because of the total lack of modification marks.3

How Microsoft expect anyone to develop using any technology they introduce with so many limitations.
Moi a Microsoft dumb enthusiast said to myself : hey dude you are a developer stop whining about the app gap bust a move create decent array of apps and release them, went into a full project management mode wrote requirements did sketches and some prototypes, time to execute.
1. first app: image files organizer, viewer , with some light editor capabilities and album creator after some work i came to discover that you don't have a proper file system APIs to show a folder tree view in my app "WTF" there are work arounds and dirty solutions but seriously? i can only access the stupid media folders created by Microsoft and that's it.
so i ditched the apps until uwp become a development tools with target audience other than kids who eat crayons, and while using "Edge" i thought to my self : "you know what dude extensions are cool and if you do something like a speed dial it would be awesome"
fire up my text editor started writing my extension to discover that:
"you cannot use localStorage from local HTML files".
moral of the story
MS is failing with consumers not because people hate MS but rather MS hates itself like no engineer over there said to him self this is fking stupid ?
other limitations :
no proper system tray access
no registry access what so ever
and i have started 2 days ago.
yeah Ms this is the main app gap problem the uwp sucks big time. compared to android Java which has a great access to every aspect of the device even apple provide better APIs for their systems.
if uwp is MS future then rip MS.
please i stand corrected if anyone knows better.2 -
The rear ducking continues. We've built a reliable translator in the dumbest fucking way possible, it's just lovely. I simply reused the structure for feeding data to the VM assembler, an array of arrays, where there's one array of (ins [args]) per node in the parse tree.
It's nice because nodes can be solved out of order without affecting the actual sequence in which the instructions are output. And if one statement (node) equals multiple instructions, you just push multiple entries to the corresponding array, or push nothing if you need to output nothing. Easy as goblin pie.
This is enough to convert an input language to the assembly-like intermediate representation we use for the virtual machine. So then there's doing it backwards: walk the same array of arrays, and map those virtual instructions to a physical architechture. I guess I could do the encoding to native binary myself, it'd certainly be interesting to try, but I'm burnt-out already so I'll just use fasm for now.
Initial test: wrote a test program in my own stupid language, ran the translator, dump output to file, assemble that with fasm, run with r2 -d.
Crashes? No.
Runs fine? Yes and no.
For fuck's sake, I don't have syscalls. Mainly because the VM doesn't have an operating system, lmao. I was testing virtual programs by just freezing state, terminating, then dumping the fucking registers and stack to the console, we have no I/O to speak of. Not even a real 'exit', VM handles that by reading a return value every step like a mentally damaged son of a bitch.
So anyway, I manually paste the linux mambo, you know:
mov rax,60
mov rdi,0
syscall
And NOW our program can end execution without crashing.
Okay then, so does the test code work correctly?
** DRUM ROLL **
Yes.
Ladies and gentlemen, mother fucking PESO is now a compiled language, and going forward I will be expectantly receiving your marriage proposals for reviewing. Oh, but not so fast, we still need a frontend...
Well, we'll handle that in the next few days. I'm just glad to be *nearly* finished with this fucking compiler, I want nothing to do with anything else ever, but we know that's not going to happen, so Lord please end my pain.
No sponsor as this rant has been paid for by tax evasion. -
I guess I'll just trouble shoot this controller for an hour or so before I check the file-tree and find out that I'm editing a stale file of the same name in the root instead of the nested file...
-
Rubber ducking your ass in a way, I figure things out as I rant and have to explain my reasoning or lack thereof every other sentence.
So lettuce harvest some more: I did not finish the linker as I initially planned, because I found a dumber way to solve the problem. I'm storing programs as bytecode chunks broken up into segment trees, and this is how we get namespaces, as each segment and value is labeled -- you can very well think of it as a file structure.
Each file proper, that is, every path you pass to the compiler, has it's own segment tree that results from breaking down the code within. We call this a clan, because it's a family of data, structures and procedures. It's a bit stupid not to call it "class", but that would imply each file can have only one class, which is generally good style but still technically not the case, hence the deliberate use of another word.
Anyway, because every clan is already represented as a tree, we can easily have two or more coexist by just parenting them as-is to a common root, enabling the fetching of symbols from one clan to another. We then perform a cannonical walk of the unified tree, push instructions to an assembly queue, and flatten the segmented memory into a single pool onto which we write the assembler's output.
I didn't think this would work, but it does. So how?
The assembly queue uses a highly sophisticated crackhead abstraction of the CVYC clan, or said plainly, clairvoyant code of the "fucked if I thought this would be simple" family. Fundamentally, every element in the queue is -- recursively -- either a fixed value or a function pointer plus arguments. So every instruction takes the form (ins (arg[0],arg[N])) where the instruction and the arguments may themselves be either fixed or indirect fetches that must be solved but in the ~ F U T U R E ~
Thusly, the assembler must be made aware of the fact that it's wearing sunglasses indoors and high on cocaine, so that these pointers -- and the accompanying arguments -- can be solved. However, your hemorroids are great, and sitting may be painful for long, hard times to come, because to even try and do this kind of John Connor solving pinky promises that loop on themselves is slowly reducing my sanity.
But minor time travel paradoxes aside, this allows for all existing symbols to be fetched at the time of assembly no matter where exactly in memory they reside; even if the namespace is mutated, and so the symbol duplicated, we can still modify the original symbol at the time of duplication to re-route fetchers to it's new location. And so the madness begins.
Effectively, our code can see the future, and it is not pleased with your test results. But enough about you being a disappointment to an equally misconstructed institution -- we are vermin of science, now stand still while I smack you with this Bible.
But seriously now, what I'm trying to say is that linking is not required as a separate step as a result of all this unintelligible fuckery; all the information required to access a file is the segment tree itself, so linking is appending trees to a new root, and a tree written to disk is essentially a linkable object file.
Mission accomplished... ? Perhaps.
This very much closes the chapter on *virtual* programs, that is, anything running on the VM. We're still lacking translation to native code, and that's an entirely different topic. Luckily, the language is pretty fucking close to assembler, so the translation may actually not be all that complicated.
But that is a story for another day, kids.
And now, a word from our sponsor:

Consider an API that uses the HTTP path to represent position in a tree that literally represents a file tree with minimal constraints, and GET/PUT/DELETE methods to read, write and destroy the nodes. How would you encode read/write operations to per-node metadata? The kinds of metadata are static and around 4, so inventing HTTP verbs for each of them is infeasible but filtering is not necessary.
Options considered so far:
- toplevel resources alongside a namespaced /data such as /acl, /lock
- magic keywords to the Range header (this is apparently compliant)
- mimetypes such as text/plain+acl
- SETPROP / PROP methods in the spirit of WebDAV
- headers (I worry this may become an immitigable bottleneck really fast)
I'm looking for any kind of suggestion or insight, not perfect answers.
I read the WebDAV specification and I won't even suggest that I'm trying to align with it, the only protocol I'd seen in the past with comparable scope bloat is WebRTC.22
