Search - "ascii code"
-
So i was playing around with terminal apps in node.js a few weeks ago and made a CLI version of devrant. Images get converted to ascii just for fun. This is about was far as it goes for me though - anyone want to take it over? (The code is shit - this was a midnight proof of concept). Currently there's pretty much just the rant listings, the login works too but I think @dfox would need to approve it's use.
Next script I'm writing is going to be a terminal rant posting tool so I can rant from my server 😉
$ rant -m "fml" -f ~/screenshot.jpg -t "lol"20 -
The GET /users endpoint will return a page of the first 13 users by default.
To request other pages, add |-separated querystring with the limit and offset, as roman numerals enclosed in double quotation marks. Response status is always equal to 200, plus the total count of the resource, or zero when there's an error.
You can include an array of friends of the user in the result by setting the request header "friends" to the base64-encoded value of the single white pixel png.
Other metadata is not included by default in responses, but can be requested by appending ?meta.json to any endpoint, which will return an xml response.
If you want to update the user's profile picture, you can request an OAuth token per fax machine, followed by a pigeon POST capsule containing a filename and a rolled up Polaroid picture. The status code attached to the return postal dove will be the decimal ASCII code for a happy smiley on success, and a sad smiley if any field fails form validation.

Wtf Microsoft...
Found out the hard way that copying a line of code from Teams chat will sometimes convert the spaces into unrecognized ASCII char.
Spent a few hours yesterday to fix the bad chars.
🤡👍16 -
I-I totally did n-not spend half an hour on this...
(here's a gist for you: https://gist.github.com/moriczgergo...)5 -
I Just created My first code in brainfuck.
My First reaction was why was this made, but as I continued it seemed to make some sense, even though All I was using was some random ascii symbols6 -
Interested in the "If 42 is the answer? What is the question?" diversity. 🤔
*me going to wikipedia*
searching for 42
buncha math stuff whatever
matrix sum... interesting 🤨
(is 42 maybe related to dimensions?)
*sees a lot of programs relations where 42 is considered magical in themselves*
"The ASCII code 42 is for the asterisk symbol, being a wildcard for everything."
*literally speechless* 😮8 -
Crazy... Hm, that could qualify for a *lot*.
Craziest. Probably misusage or rather "brain damaged" knowledge about HTTP.
I've seen a lot of wild things when devs start poking standards, but the tip of the iceberg was someone trying to use UTF-8 in headers...
You might have guessed it - German umlauts. :(
Coz yeah. Fucktard loved writing everything in german, so why not write custom header names in german.
The fun thing is: It *can* work, though the usual sane thing is to keep it in ASCII range for the obvious reason that using UTF-8 (or ISO-8859-1, which is *not* ASCII) is a gamble you gonna loose.
The fun game was that after putting in a much needed load balancer between services for monitoring / scaling etc suddenly *something* seemed off.
It took me 2 days and a lot of Wireshark hoola hooping to find out why, cause the header was used for device detection aka wether it's a bot or not. Or in the german term the dev used: "Geräte-Art".
As the fallback was to assume a bot, but only rate limit based on IP, only few managed to achieve the necessary rate limit to get blocked.
So when I say *something* seemed off, I really mean a spooky kind of "sometimes IP blocked for seemingly no reason at all".
Fun stuff. The dev btw germanized everything. Untangling the code base was a lot of non fun. -.-6 -
If you host a forum for dev discussions, make sure that, even in code blocks, every single or double quote will be replaced by quirky typographic quote characters that resemble their ASCII equivalents so closely that cut-and-paste programming will be punished by hours of searching the error in the wrong place.4

Atlasssian Bitbucket has broken umlauts since version 8.0 ...
https://jira.atlassian.com/browse/...
Ladies and gentleman,
it's the year 2022.
In the internet, dat "Neuland" as Mama Merkel used to say, Atlassian managed to revert back to the good old times of ASCII.
Who needs proper multibyte charset support anyway?
Just display broken shit - as broken as the quality management of that misanthropic chum bucket company called Atlassian.
Oh and the last upgrade to Confluence broke, too.
Was just very needed because of an remote code execution.
Cause you know the usual deal. Oops zero exploit, let's make it public, telling our customers that in cloud their data is safe, otherwise they need to shut off their instances or pray that they have a WAF that can filter strings...
What broke you might ask?
Unique constraint in database, the migration wizard loved to add few extra rows, solution was to fry the rows while instance running, followed by immediate cache drop, otherwise fun started again.
I hate Atlassian.4 -
Ah, the little subtle things we have to iron out as we progress from Junior Developer to Medior Developer.. things like:
- knowing the difference between a carriage return and a line feed (although having worked with analog typewriters helps) and later knowing that Unix-based systems and Windows NT-based systems implement it differently..
- knowing that serialization is important because not all computers interpret data the same way and some computers allocate 4 Bytes for a construct, others 16 Bytes.. and then we get the funkiness of transferring character sets between machines..
- knowing that a whitespace character is not only an actual space (as is known in ASCII as code 32). This one can cause even medior developers a headache, as in: why the fuck does this string function say that "hello I am a duck" and "hello I am a duck" are not the same?! Turns out then in the debugger that when you expand every character in the string you see that string1 contains 32 32 32 32 as usual.. but then string2 contains -96 -96 -96 -96 and you're like.. what the fuck..? Then you know you have to throw \\h regex at it. Haha.
- finalizing our objects and streams (although modern languages do that for us).. otherwise we have to do funky shit like trying to find what's locking a file, which is not so easy to figure out.
- figuring out why something won't work often requires you to not only break down the problem in smaller steps, to use a debugger, but sometimes it's even better to just create a proof of concept, slap some minimal code in there and debug that.. much easier.
- etc.

Since my first post was a success, here's another shameless hack-- in this case, ripping a "closed" database I don't usually have access to and making a copy in MySQL for productivity purposes. That was at a former job as an IT guy at a hardware store, think Lowes/Rona.
We had an old SCO Unix server hosting Informix SQL (curious, anyone here touched iSQL?), which has terminal only forms for the users to handle data, and has keybindings that are strangely vi based (ESC does commit changes. Mindfsck for the users!). To add new price changes to our products, this results to a lengthy procedure inside a terminal form (with ascii borders!) with a few required fields, which makes this rather long. Sadly, only I and a colleague had access to price changes.
Introducing a manager who asks a price change for a brand- not a single product, but the whole product line of a brand we sell. Oh and, those price changes ends later after the weekend (twice the work, back at regular price!)
The usual process is that they send me a price change request Excel document with all the item codes along with the new prices. However, being non technical, those managers write EVERYTHING at hand, cell by cell (code, product name, cost, new price, etc), sometimes just copy pasted from a terminal window
So when the manager asked me to change all those prices, I thought "That's the last time I manually enter all of this sh!t- and so does he". Since I already have a MySQL copy of the items & actual (live) price tables, I wrote a PHP backend to provide a basic API to be consumed to a now VBA enhanced Excel sheet.
This VBA Excel sheet had additional options like calculating a new price based on user provided choices ("Lower price by x $ or x %, but stay above cost by x $ or x %"), so the user could simply write back to back every item codes and the VBA Excel sheet will fetch & display automatically all relevant infos, and calculate a new price if it's a 20% price cut for example.
So when the managers started using that VBA sheet, I had also hidden a button which simply generate all SQL inserts for the prices written in the form, including a "back to regular price" if the user specified an end date, etc.
No more manual form entry for me, no more keyboard pecking for the managers with new prices calculated for them. It was a win/win :)1 -
Who would be interested in reviewing an old peice of Python code I wrote..? It's a few years old, and it uses basic procedual generation to cypher text (entry, or ASCII files) using a hashed password. It's a command line tool.
I used to brag about how "secure" it was, and now I'm curious if it is secure or not.
I plan on picking it back up and open-sourcing it, but I want to know what problems might be wrong with it now.9 -
Didn't think I had material for a rant but... Oh boy (at least at the level I'm at, I'm sure worse is to come)
I'm a Java programmer, lets get that out of the way. I like Java, it feels warm and fuzzy, and I'm still a n00b so I'm allowed to not code everything in assembly or whatever.
So I saw this video about compilers and how they optimize and move and do stuff with the machine code while generating the executable files. And the guy was using this cool terminal that had color, autocomplete past commands and just looked cool. So I was like "I'll make that for my next project!"
In Java.
So I Google around and find a code snipped that gives me "raw" input (vs "cooked" input) and returns codes and I'm like 😎. Pressing "a" returns 97 (I think that's the ASCII value) and I think this is all golden now.
No point in ranting if everything goes as planned so here is the *but*
Tabs, backspaces and other codes like that returned appropriate ASCII codes in Unix. But in windows, no such thing. And since I though I'd go multiplatform (WORA amarite) now I had to do extra work so that it worked cross platform.
Then I saw arrow keys have no ASCII codes... So I pressed a arrow key and THREE SEPARATE VALUES WERE REGISTERED. Let me reiterate. Unix was pretending I had pressed three keys instead of one, for arrow keys. So on Unix, I had to work some magic to get accurate readings on what the user was actually doing (not too bad but still...). Windows actually behaved better, just spit out some high values and all was good. So two more systems I had to set up for dealing with arrow keys.
Now I got to ANSI codes (to display color, move around the terminal window and do other stuff). Unix supports them and Windows did but doesn't but does with some Win 10 patch...? But when tested it doesn't (at least from what I've seen). So now, all that work I put into making one Unix key and arrow key reader, and same for Windows, flies out the window. Windows needs a UI (I will force Win users, screw compatibility).
So after all the fiddling and messing, trying to make the bloody thing work on all systems, I now have to toss half the input system and rework it to support UI. And make a UI, which I absolutely despise (why I want to do back end work and thought this would be good, since terminal is not too front end).2 -
Feeling like a boss! 😎
Long story short:
Solved a formating issue in a program at work by using ancii code 32.
Even my team lead didn't think of that solution!4 -
So there is this program with legacy code from 15 years ago the client is in love with. Every time we try to accomplish something it proves that the mf who wrote it was so lazy and incompetent that he should have never chosen this profession. Goto, one-two letter for type and variable names. Dude even wrote an ascii decoder as if he would be payed for lines of code. Today we found a code where a rows of data was misindexed by one (we incorrectly assumed that we could extract some data from it but the column we wanted to use was just there for decoration, it was not actually used). the calculations the system uses are replicated for each interface with duplicate lines of code so the same binary data can show different values because of the multipliers.
If I could I woukd go back in time and bang the guy's head to the desk emphasising each word like "You - should - quit - and - never - ever - write - code -again"6 -

Almost everyone nowadays uses a PC, Laptop, Smartphone but sadly not even 60% of the total potential of the hardware is being used.
.
And no - you don't require custom cooling to use the whole 100% of the total potential, stock cooling is more than enough.
.
IRL "programmers" these days don't do any fscking effort to optimise their code and give it all up as some kinda shitty "hot patch" - code of their looks disturbing with no security features + optimisation. (wAnBlOwS products remain an example)
.
Even when you're using python you can push your project to limits. Instead of shoving face-size ASCII banners why don't chaps stress test their projects? Oh I forgot the community runs on show-offs and CVs ...
.
Note to Self : Optimisation is the key to integrate Technology with Nature.2 -
Hello C++ / C programmers. I've noticed my professor putting the ASCII code of a character into an int instead of just using a char to store it. When he does this he's not doing math or anything with them, so is there any advantage to it? My TA mentioned something about memory alignment, but I'm not experienced enough to know how something being aligned differently in memory would help or hurt a program.5
-
I should try to put ascii arts of pepe memes instead of meaningful error handling messages in my code, this way I would know for sure if people are actually not just patching fucking try catch silence everywhere instead of doing proper code.
I should probably do the same with documentation as well while being at it. -
First post on devRant... Aaaaand it's university hw... I can't wrap my head around this...
So, the problem is: I have to implement writing and printing 64 bit decimal integers (negative and positive with 2s complement) in NASM Assembly. There are no input parameters, and the result should be in EDX:EAX. The use of 64 bit registers is prohibited.
There is a library which I can use: mio.inc
It has these functions:
- mio_writechar (writes the character which corresponds to the ASCII code stored in AL to console)
- mio_readchar (reads an ASCII character from console to AL)
It also has to manage overflow and backspace. An input can be considered valid or invalid only after the user hits Enter... It's actually a lot of work, and it's just the first exercise out of 10... 😭
The problem is actually just the input - printing should be easy, once I have valid data...
Please help me!3 -
I think I just wrote a non-ASCII comma or space somewhere in my code... damn me for having so many keyboards...8

Maybe you people will like this story.
The past semester I studied Java in class. First time doing object oriented programming, I had an annoying teacher but got the hang of it. I still miss C from the last year.
As a final project we had to do any program and apply some stuff we saw in class (The program should have an array list, use interfaces, bla bla bla bery simple stuff). It also must have a complete documentation, a manual and a diary explaining what was developed every week. Bonus points if it was in a repository like GitLab.
I wanted to do an RPG game in a matrix, like a rougelike or an old FF game, that should be a map or two, a few monsters and items and that's it. Enough to show what can I do and to have enough excuses to apply everything that the teacher asked. I had a team with two friends who wanted to do the same.
After making accounts in three different pages that apparently would help us to be more organized (One to make charts and two task trackers) I lost all patience and made an account in GitLab, made the basic classes that we had defined in a chart, divided the tasks and put them in to do on GitLab and we started to work.
One of my companions caused a lot of problems. First, he didin't wanted to learn how to use GitLab (I simply asked them to do merge requests) and he insisted to use GitHub. Then he started to say that using the console version was even better (Pretty sure he said thet he never used Git, but maybe was gas poisoning). The GitLab repository never had a single commit to his name.
BUT WAIT IT GETS BETTER all the entire time, he was complaining about the graphical interface of the game, wanting to use some SDK for RPGs that he found. I told him that we will see that at the end, that first we should have all the mechanics done, test it in ASCII in the console and then, if we have time, we will put the visual interface, separated and optional from the main program to avoid problems.
After two weeks where he gave me very simple standard stuff late, half done and through Google Drive, I discovered he was most of the time working on... the graphical interface SDK! He took the job already done by me and the other guy and making a pretty hardcoded integration with the graphical interface and making everything that he tought it would be necesary. Soon enough the GitLab repository was totally outdated and completly useless. He had the totallity of the project in his half broken laptop, and sometimes he gave us a zip with all the code, outdated after a few minutes. Most of the stuff that I made was modified, a lot of the code was totally unknown to what it was and I had no idea even of how the folders were organised.
We had a month to finish it. I got totally disconected from the project and just hoped for the best, sometimes doing a handful of generic and adaptable lines of code for a specific thing (Funny enough, many core mechanics were nonexistent). The other guy managed to work more on the project, mostly fixing the mess that the guy did: apparently he didin't read the documentation of the SDK and just experimented and saw tutorials and tried to figure out how to do what he wanted.
Talking about documentation: we dont had yet. The code wasn't even commented propely. We did all that the last week and some stuff was finished the last night. The program apparently worked but I had no idea.
Thank God, the teacher just looked over everything and was very impressed by the working camera and the FF tiles. I don't think he saw the code or read too much of the documentation, much less when I directly wrote how I lost all access to the project.
I had a 10/10. I didin't complained. Most easy and annoying ten I ever had. I will never do a project with that guy. -
I just wondered. What if we replaced every $ sign in the PHP source code with € (and of course also all the corresponding ASCII values etc.). Would that allow for the much better syntax of variables €myVar? Just curious...4
-
man if i could figure out how to do stuff and had the money to do stuff i'd be dangerous as fuck, but as of now i can only posit questions... it sucks.
Examples:
- What do modern browsers/crawlers do when hit with, say, an "HTTP 450 Blocked by Windows Parental Controls" or an "HTTP 374" status code?
- What happens if I do <xyz minor edge case thing> on <system?> (just use your imagination, this happens for every edge case i can think of for every system and the list wouldn't fit in a few megs' worth of half-byte ASCII, much less *here*)
- What if I made like a board to fuck with busses while systems were on? Press a button and for like five bus clock cycles pins like 6 and 7 are shorted? That sort of thing. As for system/bus types, *literally any* (old consoles with expansion ports, PCI/-e/-X/whatever, southbridge, etc.)
- What if I did <filetype> shenanigans by doing <something indescribably horrible> to this file? How do things react?3
