Search - "format string"
-
Watching a tutorial.
* Uses the mouse in order to select and format code, instead of the shortcuts VS code provides
* Does multiple "bool == true"-comparisons
* Doesn't use string interpolation and makes unnecessary .toString() calls
* Adds fucking parentheses around the whole fucking expression he wants to assign
value = (expression)
* Explanations so vague, the EU wants to hire him to reform the internet
Fucking waste of time even on x2.25 speed.10 -
I'm a huge fan of the imagecreatefromstring function in PHP. I love how it can just take any image format as a string and turn it into an image!

YOU CANNOT parse CSV by just splitting the string by commas.
YOU CANNOT generate CSV by just outputting the raw values separated by commas.
CSV is not the magical parseless data format. You need to read fields in quotations, and newlines inside of fields shouldn't prematurely end the row.
Do it fucking right holy shit.15 -
Working with a delivery ordering API. Response:
Shipping label type: PDF
Label: base64encoded string
I was like, that's easy, literally two lines of code. Proceeds to convert and save the file. Then on open, bam! Format ubreadable. What the actual fuck?! Found an online converter, and tried to convert it to pdf, to see if I was missing something, but the results was the same.
Then checked the decoded string. First 3 characters: GIF
Well fuck you too! This carrier uses GIF's for it's shipping labels for 2years at least, how hard is it to change that in your fucking api response, you pice of shitbag.2 -
Well, if your tests fails because it expects 1557525600000 instead of 1557532800000 for a date it tells you exactly: NOTHING.
Unix timestamp have their point, yet in some cases human readability is a feature. So why the fuck don't you display them not in a human readable format?
Now if you'd see:
2019-05-10T22:00:00+00:00
vs the expected
2019-05-11T00:00:00+00:00
you'd know right away that the first date is wrong by an offset of 2 hours because somebody fucked up timezones and wasn't using a UTC calculation.
So even if want your code to rely on timestamps, at least visualize your failures in a human readable way. (In most cases I argue that keeping dates as an iso string would be JUST FUCKING FINE performance-wise.)
Why do have me parse numbers? Show me the meaningful data.
Timestamps are for computers, dates are for humans.3 -
SICK AND TIRED OF READABILITY VS. EFFICIENCY!!!!!!!
I HAD TO SEPARATE A 4 LOC JSON STRING, WHICH HAD AN ARRAY OF A SINGLE KEY-VALUE PAIRS (TOTAL OF 10 OBJECTS IN THE ARRAY).
ITS READABLE IF YOU KNOW JSON. HOW HARD IS TO READ JSON FORMAT IF YOU GET YOUR STYLE AND INDENTATION PROPERLY?!?
SO I HAD TO
BREAK THE POOR FREAKING JSON APART TO A FUCKING DIFFERENT YAML FILE FORMAT ONLY SO I CAN CALL IT FROM THERE TO THE MAIN CONTROLLER, ITERATE AND MANIPULATE ALL THE ID AND VALUES FROM YAML BACK TO MATCH THE EXPECTED JSON RESPONSE IN THE FRONT END.
THE WHOLE PROCESS TOOK ME ABOUT 15 MINUTES BUT STILL, THE FUCKING PRINCIPLE DRIVES ME INSANE.
WHY THE FUCK SHOULD I WASTE TIME AT AN ALREADY WORKING PIECE OF CODE, TO MAKE IT LESS EFFICIENT AND A SLIGHTLY BIT MORE READABLE?!? FML.5 -
Imagine saving Integers and Floats in a MySQL table as strings containing locale based thousand sepatators...
man... fickt das hart!
Wait, there's more!
Imagine storing a field containing list of object data as a CSV in a single table column instead of using JSON format or a separate DB table.... and later parsing it by splitting the CSV string on ";"...7 -
Normal person : 365 + 1 = 366
Developer dealing with julian dates : 365 + 1 = 1(New year)
Business person : 365 + 1 = 001 (because they like symmetry in their file names with dates)
We found this BUG, now we are celebrating our new year by changing code in each of script to format string accordingly.2 -

Me and my bestfriend joined a hackathon way back since we were in college. The task was to fetch JSON data from a REST APIs then we were given a sample link so we can compare the output between the expected output with our own. But the response from the actual API is not in JSON format, it's a string so we need to do dozens of string manipulation to match the expected output.
To submit our work we are given our own subdomain to upload our work and setup the environment and the URL will be submitted. We know how to complete the challenge but the time is running out and we were in panic mode so my friend mistakenly submitted the URL used to compare the output. We already expected to fail the challenge but what the fuck, we got a perfect score and won the challenge.1 -

Conversation yesterday (senior dev and the mgr)..
SeniorDev: "Yea, I told Ken when using the service, pass the JSON string and serialize to their object. JSON eliminates the data contract mismatch errors they keep running into."
Mgr: "That sounds really familiar. Didn't we do this before?"
SeniorDev: "Hmmm...no. I doubt anyone has done this before."
Me: "Yea, our business tier processor handled transactions via XML. It allowed the client and server to process business objects regardless of platform. Partners using Perl,
clients using Delphi, website using .aspx, and our SQLServer broker even used it."
Mgr: "Oh yea...why did we stop using it?"
Me: "WCF. Remember, the new dev manager at the time and his team broke up the business processor into individual WCF services."
Mgr: "Boy, that was a crap fest. We're still fighting bugs from the mobile devices. Can't wait until we migrate everything to REST."
SeniorDev: "Yea, that was such a -bleep-ing joke."
Me: "You were on Jake's team at the time. You were the primary developer in the re-write process saying passing strings around wasn't the way true object-oriented developers write code.
So it's OK now because the string is in JSON format or because using a JSON string your idea?"
SeniorDev turns around in his desk and puts his headphones back on.
That's right you lying SOB...I remember exactly the level of personal attacks you spewed on me and other developers behind our backs for using XML as the message format.
Keep your fat ass in your seat and shut the hell up.3 -
The infuriating edgecases of python copypasta.
If you're like me, and you find it easier to noodle in notepad++ and the console, then you may have encountered this peculiar bug.
Try padding blank spaces on an empty string variable, and follow it with print(blanks + str(var))
#for any variable
Now copypaste that along with at least one other line at the same time.
Observe how no matter what you do, print will always output the blanks variable on a separate line, with quotes.
Try rewriting right-justify? No good.
Try using f-format strings? No good.
Raw strings? Inspecting bytes to see where the newlines and carriage returns are being inserted? Nothing.
Copypaste with multiple strings will *always* insert quotes and a new line when printing *any* variable with a string thats been justified.
And this is 100% non-congruent with pasting the same *line* of code *by itself*, which works as intended, no quotes or additional new lines are inserted.
I just went ahead, turned the snippet into a function, and called it from there, which solved the problem entirely.6 -
Image relevant.
Tried getting puter to talk, puter no want to talk.
Me sad.
Me tell puter to stay put and listen at 4444.
External device doesn't do shit.
Me sad.
Read the docs. Nothing. Written like a 5 year old would.
Be angry, how do I put external device into tcp/ip mode? No one knows, the docs don't know.
I get frustrated and pull the USB cable out of it.
Mfw it starts spitting out requests to my server with no end in sight.
Mfw the requests all just repeat.
Mfw the docs tell me to acknowledge a request I have to respond with a content type of
"application/x-www-form-urlencoded"
How.
Not possible.
Mfw I decide to dissect a request to check it's accept header.
Mfw it says text/plain.
Great, no idea in what format the thing expects it.
Try writing out query string plainly.
It fucking works.
Why can't people just learn to write proper documentation.5 -
Fuck this I need to ventilate.
Thinking about job change because maintaining and extending 3 years old codebase (flask project) is FUCKIN exhausting. It was badly written since start by someone who obviously didn't know much about python. (Going by commit history.)
Examples:
- if var != None / if var == None
- if var is not None / if var is None (well..)
- Returning self-parsed obscure JSONs from dict variable
- Serializing dictionaries into database by str() (both sqlalchemy and mysql support JSON format) - THEY ARE ALMOST UNUSABLE OTHER WAY AROUND (luckily, python can deal even with that)
- celery tasks, the way they are called they BLOCK the whole flask (not bad in itself, but if connection breaks there are no errors, nothing it just hangs)
- obscure generator/yielding that contains return of flask's response in itself
- creating fifteen thousands of variables one by one where they would look so nicely as dict keys, and hey they are then both MANUALLY SERIALIZED into returning dict by "%s" (string formatting) [okey, some of them are objecst like datetime but MATE WTF]
- many, many more, PEP lint shall not pass
I would rather deal with fresh startup owners wanting me to program unicorns in one week then trying to extend and manage zombie-like projects.
Nothing personal against the firm I actually like the place.3 -
How it started:
Need to replace in a lot of SQL files certain stuff...
find . -type f -iname '*.sql' -exec sed -i 's|new|old|g' {} \;
12 hours later that find executed a shell script containing roughly 120 lines of text pipelining.
The jolly of inconsistent workflows.
Different SQL format stylings... Makes fun when single line string replace needs to be extended to multiline RegEx handling. Or matching SQL comment configuration..
Different line endings. MacOS, Windows, Unix, Bukkake.
Different charsets / collations. Anyone wants latin1_swedish_ci... utf8... utf16... :/
Realizing some people even left sensitive data inside the SQL files (e.g. API Tokens..... Yayyyyyyy).
...
Ugh. It's never a one liner. It's never easy. -.-
I hate cleaning up messy shit.3 -
I fix antique code for a living and regularly come across code like this, and this is actually the good stuff!
Worst usecase for a goto statement? What do you think?
int sDDIO::recvCount(int bitNumber){
if (bitNumber < 0 || bitNumber > 15) return 0; //ValidatebitNumber which has to be 0-15
//Send count request
if (!(send(String::Format(L"#{0:X2}{1}\r", id, bitNumber)) && flushTx())){
bad: //Return 0 if something went wrong
return 0;
}
String^ s = recv(L"\r"); //Receive request data
if (s->Length != 9) goto bad; //Validate lenght
s = s->Substring(3, 5); //Take only relevant bits
int value; //Try to parse value and send to bad if fails
bool result = Int32::TryParse(s, value);
if (!result) goto bad;
int count = value - _lastCount[bitNumber]; //Maximumpossible count on Moxa is 65535.
if (count < 0) count += 65536; //If the limit reached, the counter resets to 0
_lastCount[bitNumber] = value; //This avoids loosing count if the 1st request was
//made at 65530 and the 2nd request was made at 5
return count;

python machine learning tutorials:
- import preprocessed dataset in perfect format specially crafted to match the model instead of reading from file like an actual real life would work
- use images data for recurrent neural network and see no problem
- use Conv1D for 2d input data like images
- use two letter variable names that only tutorial creator knows what they mean.
- do 10 data transformation in 1 line with no explanation of what is going on
- just enter these magic words
- okey guys thanks for watching make sure to hit that subscribe button
ehh, the machine learning ecosystem is burning pile of shit let me give you some examples:
- thanks to years of object oriented programming research and most wonderful abstractions we have "loss.backward()" which have no apparent connection to model but it affects the model, good to know
- cannot install the python packages because python must be >= 3.9 and at the same time < 3.9
- runtime error with bullshit cryptic message
- python having no data types but pytorch forces you to specify float32
- lets throw away the module name of a function with these simple tricks:
"import torch.nn.functional as F"
"import torch_geometric.transforms as T"
- tensor.detach().cpu().numpy() ???
- class NeuralNetwork(torch.nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__() ????
- lets call a function that switches on the tracking of math operations on tensors "model.train()" instead of something more indicative of the function actual effect like "model.set_mode_to_train()"
- what the fuck is ".iloc" ?
- solving environment -/- brings back memories when you could make a breakfast while the computer was turning on
- hey lets choose the slowest, most sloppy and inconsistent language ever created for high performance computing task called "data sCieNcE". but.. but. you can use numpy! I DONT GIVE A SHIT about numpy why don't you motherfuckers create a language that is inherently performant instead of calling some convoluted c++ library that requires 10s of dependencies? Why don't you create a package management system that works without me having to try random bullshit for 3 hours???
- lets set as industry standard a jupyter notebook which is not git compatible and have either 2 second latency of tab completion, no tab completion, no documentation on hover or useless documentation on hover, no way to easily redo the changes, no autosave, no error highlighting and possibility to use variable defined in a cell below in the cell above it
- lets use inconsistent variable names like "read_csv" and "isfile"
- lets pass a boolean variable as a string "true"
- lets contribute to tech enabled authoritarianism and create a face recognition and object detection models that china uses to destroy uyghur minority
- lets create a license plate computer vision system that will help government surveillance everyone, guys what a great idea
I don't want to deal with this bullshit language, bullshit ecosystem and bullshit unethical tech anymore.11 -
Microsoft.Graph has filtering capabilities for dates, which is great.
Format is: "2018-04-12T12:00:00Z"
Doesn't natively support string conversion of a DateTime to match the pattern... Nor does Graph accept any date formats such as the "s" parameter for sortable dates, which goes into milliseconds, etc.
DateTime.ToString("derp");
Sometimes I wish I was a Java Dev.1 -
Unicode's biggest problem is that it isn't a streamable format. Given a section of a Unicode string, it's impossible to assert that the next character won't be an accent or zwj or other modifier. This means that it's impossible to convert stdin into an iterator over canonicalized Unicode graphemes.12

So the guy who i mentioned previously with his shitty csv made webservice which i needed to use.
It returned utf-8 encoded xml:
- in file the header contained central europe encoding
- the xml had more roots
- basically he only put his csv format inside xml tags
- csv contained html tags but there wasnt cdata
Now work with this lol
I neded to cut this shit with string functions and also some numeric data get with regexp from htm table td's

I'm doing work during the weekend. Just to parse this line of json.
Argh, what drive me nuts is after discovering that json response wasn't proper.
*sample - from what i seen*
{
head= {
data=value,
data=value,
}
}
This is my first time seeing json response with =. Since my assignment is to retrieve the response.
I cheated by calling replace over and over to correct the string of response to correct json format.
That is actually production stuff. Knowing that makes me sick to the stomach.7 -
I can't imagine any worse decision than the one to make document.cookie accessed as the string format it's actually in.3

See if you can notice the error is this schema. Don't copy and paste it. I change some format to obsfucate the real data naming, but this schema error is still up there
Just wasted my 30 minutes staring at this10 -
I have to go through roughly 700 data entries and adjust the system's data accordingly ... by hand.😑
We don't have the tools to automate this reliably, the only available tool, tells you that an error occured and what happened but not where. That would've been kinda helpful...
The problem is that the respective data object of the data entry often contains a phone number, which has to be in a standardized format ... which it is not. Every number is formatted in like 10 variations!? A dozen different separators like spaces, commas, slashes and hyphens. And it must be edited manually 😖
My solution: built a goddamn chrome extension to format the string on click. Done. Saves a few seconds each time and a lot of headache in future. Of course given the correctness of the extension.4 -
I hate when programming books have shit code examples.
Just came across these, in a single example app in a Go book:
- inconsistent casing of names
- ignoring go doc conventions about how comments should look like
- failing to provide comments beyond captain obvious level ones
- some essential functionality delegated to a "utils" file, and they should not be there (the whole file should not exist in such a small project. If you already dump your code into a "utils" here, what will you do in a large project?)
- arbitrary project structure. Why are some things dumped in package main, while others are separated out?
- why is db connection string hardcoded, yet the IP and port for the app to listen on is configurable from a json file?
- why does the data access code contain random functions that format dates for templates? If anything, these should really be in "utils".
- failing to use gofmt
These are just at a first glance. Seriously man, wft!
I wanted to check what topics could be useful from the book, but I guess this one is a stinker. It's just a shame that beginners will work through stuff like this and think this is the way it should be done.3 -
I use the ICU format often for translation because it's simple enough and supported on many platforms. It's something of a standard so I can use the same translation string format and similar library functions everywhere.
ICU is like a really simple templating language, somewhere between printf and something like smarty or twig simplified and specifically intended for internationalisation.
I updated a library providing ICU compatible parsing and formatting for one of the platforms I'm using and find tests break. I assume that only thing to change is the API. ICU very rarely changes and if it did it would be unexpected for it to break the syntax in a major way without big news of a new syntax.
The main contributor of the library has changed since some time last year. Someone else picked up the project from previous contributors.
Though the library is heavily advertised as using ICU it has now switched to using a custom extended format that's not fully compatible and that is being driven by use case demand rather than standardisation.
Seems like a nice chap but has also decided for a major paradigm shift for the library.
The ICU format only parses ICU templates for string substitution and formatting. The new format tries to parse anything that looks XML like as well but with much more strict rules only supporting a tiny subset of XML and failing to preserve what would otherwise be string literals.
Has anyone else seen this happen after the handover of an opensource library where the paradigm shifts?3 -
Anyone tried converting speech waveforms to some type of image and then using those as training data for a stable diffusion model?
Hypothetically it should generate "ultrarealistic" waveforms for phonemes, for any given style of voice. The training labels are naturally the words or phonemes themselves, in text format (well, embedding vectors fwiw)
After that it's a matter of testing text-to-image, which should generate the relevant phonemes as images of waveforms (or your given visual representation, however you choose to pack it)
I would have tried this myself but I only have 3gb vram.
Even rudimentary voice generation that produces recognizable words from text input, would be interesting to see implemented and maybe a first for SD.
In other news:
Implementing SQL for an identity explorer. Basically the system generates sets of values for given known identities, and stores the formulas as strings, along with the values.
For any given value test set we can then cross reference to look up equivalent identities. And then we can test if these same identities hold for other test sets of actual variable values. If not, the identity string cam be removed, or gophered elsewhere in the database for further exploration and experimentation.
I'm hoping by doing this, I can somewhat automate the process of finding identities, instead of relying on logs and using the OS built-in text search for test value (which I can then look up in the files that show up, and cross reference the logged equations that produced those values), which I use to find new identities.
I was even considering processing the logs of equations and identities as some form of training data perhaps for a ML system that generates plausible new identities but that's a little outside my reach I think.
Finally, now that I know the new modular function converts semiprimes into numbers with larger factor trees, I'm thinking of writing a visual browser that maps the connections from factor tree to factor tree, making them expandable and collapsible, andallowong adjusting the formula and regenerating trees on the fly.7 -
Aka... How NOT to design a build system.
I must say that the winning award in that category goes without any question to SBT.
SBT is like trying to use a claymore mine to put some nails in a wall. It most likely will work somehow, but the collateral damage is extensive.
If you ask what build tool would possibly do this... It was probably SBT. Rant applies in general, but my arch nemesis is definitely SBT.
Let's start with the simplest thing: The data format you use to store.
Well. Data format. So use sth that can represent data or settings. Do *not* use a programming language, as this can neither be parsed / modified without an foreign interface or using the programming language itself...
Which is painful as fuck for automatisation, scripting and thus CI/CD.
Most important regarding the data format - keep it simple and stupid, yet precise and clean. Do not try to e.g. implement complex types - pain without gain. Plain old objects / structs, arrays, primitive types, simple as that.
No (severely) nested types, no lazy evaluation, just keep it as simple as possible. Build tools are complex enough, no need to feed the nightmare.
Data formats *must* have btw a proper encoding, looking at you Mr. XML. It should be standardized, so no crazy mfucking shit eating dev gets the idea to use whatever encoding they like.
Workflows. You know, things like
- update dependency
- compile stuff
- test run
- ...
Keep. Them. Simple.
Especially regarding settings and multiprojects.
http://lihaoyi.com/post/...
If you want to know how to absolutely never ever do it.
Again - keep. it. simple.
Make stuff configurable, allow the CLI tool used for building to pass this configuration in / allow setting of env variables. As simple as that.
Allow project settings - e.g. like repositories - to be set globally vs project wide.
Not simple are those tools who have...
- more knobs than documentation
- more layers than a wedding cake
- inheritance / merging of settings :(
- CLI and ENV have different names.
- CLI and ENV use different quoting
...
Which brings me to the CLI.
If your build tool has no CLI, it sucks. It just sucks. No discussion. It sucks, hmkay?
If your build tool has a CLI, but...
- it uses undocumented exit codes
- requires absurd or non-quoting (e.g. cannot parse quoted string)
- has unconfigurable logging
- output doesn't allow parsing
- CLI cannot be used for automatisation
It sucks, too... Again, no discussion.
Last point: Plugins and versioning.
I love plugins. And versioning.
Plugins can be a good choice to extend stuff, to scratch some specific itches.
Plugins are NOT an excuse to say: hey, we don't integrate any features or offer plugins by ourselves, go implement your own plugins for that.
That's just absurd.
(precondition: feature makes sense, like e.g. listing dependencies, checking for updates, etc - stuff that most likely anyone wants)
Versioning. Well. Here goes number one award to Node with it's broken concept of just installing multiple versions for the fuck of it.
Another award goes to tools without a locking file.
Another award goes to tools who do not support version ranges.
Yet another award goes to tools who do not support private repositories / mirrors via global configuration - makes fun bombing public mirrors to check for new versions available and getting rate limited to death.
In case someone has read so far and wonders why this rant came to be...
I've implemented a sort of on premise bot for updating dependencies for multiple build tools.
Won't be open sourced, as it is company property - but let me tell ya... Pain and pain are two different things. That was beyond pain.
That was getting your skin peeled off while being set on fire pain.
-.-5 -
Still as a scholar who has had his intership I decided that I was finally confident enough in my ability to apply for a small part-time programming job. I had an internship at a cool exhausting place with tons of expertise and I've proven myselve over there. So now I wanted a job on the side. Nothing special, just something that would make a little money with programming instead of washing dishes at the restaurant.
So I started at this small internet based startup (2 or 3 progammers) as a backend-oriented programmer. The working hours were amazingly compatible with my school schedule.
The lead dev also sounded like a smart guy. He had worked as a backend guy for years and had code running on verry critical public infrastructure that if it were to fail we'd be evacuated from our homes.
As a first asignment I got an isolated task to make an importer for some kind of file format that needed integration. So I asked for access to the code. I didn't get it since they were going to re-do the entire backend based on the code I wrote. I just needed to parse the file in a usable object structure. So I found out that the file format was horrible and made a quite nice set of objects that were nice. At the end of the first week or so I asked if I could get access to the code again, so I could integrate it. Answer was no. The lead dev would do that. I could however get access to my private repository.
Next week a new intern was taken to build a multiplatform responsive app. Only downside was that all the stuff he had ever done was php based websites. It wasn't going anywhere anytime soon, but I figured that that was where internships were for. So I ended up helping him a lot and taught him some concepts of OOP and S.O.L.I.D. and the occasional 30 minute rants of IndexOutOfRangeException, ArgumentException and such.
So one day he asked me how to parse a json string and retrieve a specific field out of it.
I gave him something like the following to start with:
"
JObject json;
if(!JObject.TryParse(jsonString, out json))
{
//handle error
}
string value;
if(!json.tryget("foo", out value).../// code continues
"
but then the main dev stepped in and proposed the following since it wouldn't crash on an API change:
"
dynamic json = new JObject(jsonString);
string value = json.myJsonValue;
"
After me trying to explain to him that this was a bad choise for about 15 minutes because of all kinds of reasons I just gave up. I was verry mad that this young boy was forced to use bad programming pracises while he was clearly still learning. I know I shouldn't pick up certain practises. But that boy didn't.
Almost everytime the main dev was at the office I had such a mindboggling experience.
After that I got a new assignment.
I had to write another xml file format parser.
Of course I couldn't have any access to our current code because... it was unnecesary. We were going to use my code as a total replacement for the backend again.
And for some reason classes generated from XSD weren't clear enough so after carefull research I literally wrapped xsd generated code in equivalent classes.
At that moment, I realized I made some code that was totally useless since it wasn't compatible with any form of their API or any of the other backend code. (I haven't seen their API. I didn't have access to the source.) And since I could've just pushed them generated XSD's that would've produced thesame datastructure I felt like I was a cheat. I also didn't like that I wasn't allowed to install even the most basic tooling. (git client or, Ide refactoring plugins, spelling checker etc...)
Now I was also told that I couldn't discuss issues with the new guy anymore since it was a waste of my valuable time, and they were afraid that I taught him wrong concepts.
This was the time that my first paycheck came in so I quitted my job.
I haven't seen any of the features that I've worked on. :) -
Difference between security threat and programming bug ?
Found a cool paper about format string attacks which mentioned buffer Overflow is a security threat while format string is a programming bug.
Had no idea what that really meant.
Tnx1 -
An Italian provider in his webservice documentation defines a date (birthDate) as string. Why ?
I discovered the format provided is d-m-Y, my database store it as Y-m-d and my users prefer d/m/Y (as many Italians).7 -
We use ActiveMQ as a broker in one of our system but the messages sent between applications are in query string format, God knows why. Then when one of our new features requires a JSON structure, we had to URL encode the JSON so it can be part of the message . Now the log growth is significantly higher than the version before and no longer human readable.1

Guys I need to deploy a very simple authentication API service.
You register with a username (actually an ID with a determined format), a password and uuid. You login with your username and password and if credentials are correct you get back the uuid as a response (JSON or whatever the fuck).
If you forget your password, you can use your uuid (which is confidential, very long string) in some POST request to set a new password. If you forget your username, you use the uuid again in a GET request to get back your username.
I've been looking at a bunch of solutions online and I don't think they suit my purpose exactly and all require emails (Like Firebase, AUth0, etc.) So, let me get this straight: NO FUCKING EMAILS INVOLVED PLEASE.
The above are the EXACT requirements I need for my work (for a good cause too). I fucking hate 0-requirement exploratory research tasks and I'm plagued with those. Those requirements are the only way it should work. So again, NO EMAILS INVOLVED PLEASE.
Also, please note that I have never developed an API in my life. I feel like StackOverflow will be assholes about this so I am asking this here.
I know it is very easy to do and there are probably dozens of ways to do this. I just do not know how, documentations are vague and overwhelming (or I'm just a little stupid lately). Another thing is that I am not sure of how can I do this in the most secure way. Bonus if this can be dockerized.
I know I sound a little rude,so I am sorry. It is just my frustration and depressing times I am going through that's preventing from thinking straight.6 -
Terraform + helm-chart ... I really ned a break. Who the fuck invented this shit.
The HCL format sucks
The documentation sucks
The dev tools suck
The debug output sucks
But I'm ok with that, I can manage.
But today really it shot the bird ... I can't have a fucking comma in a string? Because idk why the fuck helm-release tries to parse that fucking string and wants to make an array or whatever out of it? Why, you fucking abomination?
Something in the docs? Nah, who reads them anyway.
Because you know it's totally not strange that a string is analyse and oh wait there's a comma in it, the dev surely wants me to make an array out of it, because you know ...
So now I have to escape my fucking comma to prevent it to parse my fucking string. I just want to have a fucking string you hideous monstrosity ....1 -
Lost about 4 days debugging bug about date conversion between frontend to backend as an api request.
This shit is mad fucking annoying
The date format was always wrong.
So i gotta ask. Is it better to always have date fields as a Long which contains just a huge number that represents a timestamp, and that way whenever i want to see what date it is i would have to convert it every time on both frontend and backend from timestamp into LocalDateTime, or is it better to keep it as Date/LocalDateTime and not string/long, and that way risk fucking up the date format?
How is it done in real world projects? Whats the right way to do it and why?3 -
Function in my Dao file is:
@Query("SELECT * from appData WHERE type = :type ORDER BY id DESC")
fun getData(type: String): Flow<List<AppData>>
The database contains a column of automatically generated int primary key 'id', a column of string named 'type', and another string column named 'content'.
A Part of code from my composable function is:
val currentRetrievedDate: Date = Date()
val currentDate: String = SimpleDateFormat("dd-MM-yyyy").format(currentRetrievedDate)
var lastDateObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("lastDate")
.collect { newDataList ->
lastDateObjectList = newDataList as List<AppData>
}
}
}
if (lastDateObjectList.size>1){/*TODO*/
for (i in 1 until lastDateObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = lastDateObjectList[i]!!.id,
type = lastDateObjectList[i]!!.type,
content = lastDateObjectList[i]!!.content)
}
}
}
val lastDateObject: AppData?/* = lastDateObjectList[0] ?: null*/
lastDateObject = if (lastDateObjectList.isNotEmpty())
lastDateObjectList[0]
else null
var lastDate = lastDateObject?.content ?: "00-00-0000"
var currentStreakObjectList by remember { mutableStateOf(emptyList<AppData>()) }
LaunchedEffect(streakCounterViewModel) {
coroutineScope {
streakCounterViewModel.appDataRepository.getDataStream("currentStreak")
.collect { newDataList ->
currentStreakObjectList = newDataList as List<AppData>
}
}
}
if (currentStreakObjectList.size>1){
for (i in 1 until currentStreakObjectList.size){
LaunchedEffect (Unit){
streakCounterViewModel.deleteData(id = currentStreakObjectList[i]!!.id,
type = currentStreakObjectList[i]!!.type,
content = currentStreakObjectList[i]!!.content)
}
}
}
val currentStreakObject: AppData?/* = currentStreakObjectList[0] ?: null*/
currentStreakObject = if (currentStreakObjectList.isNotEmpty())
currentStreakObjectList[0]
else null
var currentStreak = currentStreakObject?.content ?: "0"
In this code, the last login time and last streak of user is already saved, we just have to fetch the data from the local database, make sure that there are not more than 1 occurrences of same data type in the database, and then use that data. But this, instead of using the database values, uses 00-00-0000 as the lastDate, and uses "0" as the currentStreak (which should only be used for the first not, and in some rare situations only), and is not able to retrieve data from the database properly.
The data saving and updating logic is working fine, but only the retrieval part is causing some issue.
The complete project is also uploaded on github: at HealthEase repo of tauqirnizami4 -
I am trying to extract data from the PubSub subscription and finally, once the data is extracted I want to do some transformation. Currently, it's in bytes format. I have tried multiple ways to extract the data in JSON format using custom schema it fails with an error

Please let me know if I m doing something wrong while parsing the data to JSON. Also, I am looking for examples to do data masking and run some SQL within Apache Beam4 -
today the backend dev told me that he was trying to setup typescript for the company for so long and the company resisted him but he was super proud of his achievement of getting typescript into the project and i told him. sorry I agree with the company, you're stupid
i didn't tell him he was stupid ofcourse but i told him why i thought it was an unnecessary dep
i asked him are you doing a lot of number crunching? he said no
and i told him, most of the data you're going to recieve is in a string format or in json strings
very rarely are you going to get number data
and you can easily coerce the data into whatever you want37 -
Why we don't write dereference operator while priting string(format specifiers is %s).
For example: char arr[5]={"char"};
printf("%s",arr);//print char.
If we write like printf("%s",*arr);//compile time error.1
