Q: Simple program to print from a buffer until a newline is found

CarcigenicateFor practice, I wrote a small program that goes through a string in the data section (although, it could be easily adapted to take user input), and print out the characters in the string until it finds a newline, then stops. This is by far the most complicated assembly program I've ever written. ...

Q: JSX render method in react

NeshFollowing is the piece of code which is working fine, but somehow it looks bit odd to me to have a function inside a render method and using it in both conditions. Let me know how can I improve this react code as showContainer is only adding a wrapper to the function JSX. Code - render () { co...

Those screenshots don't make the answer clearer. You can use to_clipboard to get a decent text representation — Maarten Fabré 1 hour ago
Hmm, what is wrong in the screen shots? Get I get more info? And what is to_clipboard?
the screenshots are the output of those commands.
Screen shots are not readable for people that are blind. I have translated pictures to text on request of a blind user multiple times before.
Not only does it make the site unusable for people with visual impairments, it give an unsatisfactory user experience for many users
Sorry I had no idea that blind people also use the site.
But thanks for correcting.
But this is also new for me. How is seeing text different from seeing images?
You can have a text to voice application, (changing interaction from using eyes to using ears) think how Google Translate has the "what does this sound like button"
sorry, I rarely have used google translate
not too aware of those technologies yet
Are the screenshots required too? Do I need to give proof that the code is working?
I think maybe it's better to remove those images rather.
You can change them to code blocks. The commentor has explained how
9:58 AM
to_clipboard? No idea of it too

@student there's a difference between "bugs" and "improvements" - the two things mentioned sound like "improvements", and frankly: I agree with both of them (they sound like things I've said recently, though - did I say those things? they certainly sound like me); as for "further improved" - again, that's subjective, but I'd add "remove param from GetAllData - it isn't used" - but: you may be looking for codereview.stackexchange.comMarc Gravell ♦ 22 secs ago

@pacmaninbw It was blatantly off-topic. At least it looks ok now.
But I don't Angular, so, not sure. Retracted my CV hours ago anyway.
Thanks, I already decided to leave it open, it was off-topic before the edits.
I go a step farther (I run away from any JavaScript).
I used to do that.
Turns out you can write relatively sane things in an insane language.

@Mast I'm not sure I can bend my mind that way, for a few years I tried web development and hated it, jQuery was part of the problem.
1:30 PM
Oh, yea, I try to stay away from anything front-endy
I still have a project running that should be the last of it (in Python, so it couldn't've gone that bad I thought (I thought wrong)).
@Mast Those of us that think logically might have a problem with front ends.
@pacmaninbw The only logical conclusion is front-ends defy logic.
Technically it just has a weird idea of logic.
Realistically I simply don't like it.
1:47 PM
@Mast Same here, I just don't care what something looks like as long as it's not code.
off by one or two pixels is always a problem for me.
Thanks to frameworks it doesn't have to be a matter of pixels. Just put it roughly where it should be and only use rectangles.
@An225 i updated my answer with code reviewed, it works for sure (it just used one blueprint) to isolate the logic. — cizario 42 secs ago
Python Tkinter can work with lay-outs roughly like C# can with XAML, grid-like structures.
Create a table, fill it out and let the framework do the alignment.
Use sensible sizes and it doesn't look that bad.
@Mast Flex boxes, flex boxes all the way
Who needs frameworks ;)
Python has flexboxes?
I only know those from CSS.
1:50 PM
Nah, CSS does
Oh, I forgot front end is more than just browsers...
Yes, GUI is also front-end.
Technically even CLI is front-end, but, that's semantics here.
But I much prefer CSS than TkInter, it's just so much easier to make something that doesn't look like it's from the 60s
What, and use a HTML/CSS/JS front to send your data to Python?
In a perfect world it'd be the HTML/CSS/Python stack ;)
I have news for you.
It shouldn't come as a shock to you, especially in 2020, but...
The world isn't perfect.
1:55 PM
I thought you were about to say here's a framework with that.
You really got me grounded in reality now >:(
Oh, there's probably a JS framework that runs Python.
There's a JS framework for bloody everything nowadays.
They've compiled Python to WASM so I can run Python in the browser... But... Yeah maybe not
I've heard about Anvil, but I'm sceptical about that.
> Create your UI with drag and drop
Hmm, that's a hard pass from me
@Peilonrayz That never ends well.

This is the kind of question you should ask in Code Review. — Ann Zen just now
Hi Ann Zen. In the future please use doubtful wording and link to the help center when recommending Code Review. Take, "This may be on-topic on Code Review. Please check if it is on-topic and how to post a good question before posting there." — Peilonrayz 6 secs ago
A UI should be modifiable with parameters, just like the rest of the code. No drag-and-drop, but coded up.
Yeah, I've only used drag and drop once. It was in VB.Net and I stopped doing that ASAP. Making a calculator with drag and drop... no thanks
Heh, I used VBA once to programmatically sketch HMI lay-outs. I may still have that code somewhere.
2:17 PM
That sound pretty interesting
@JimB I didn't have type Cache interface in the beginning but in the code review I was told to create an interface and use Set() and Get() through it. So I am not sure how to implement it. That's why i posted the question. — Farzam Alam 20 secs ago
@Peilonrayz Mostly for lay-out purposes, but it did help. I can probably recreate it if I don't have it handy somewhere.
cjld jcfld jc j ghyf fgu... That would never pass a code review 😱 — Legacy Code 26 secs ago
If someone told you to create that type, and you don't know why, you need to ask them. That's one of the key reasons for code review--to improve understanding. So go ask them. We can't really read your code reviewer's mind, and we don't have enough context to come to our own conclusion. — Flimzy 53 secs ago

Q: Image uploads are too slow

Franck DernoncourtImage uploads are too slow. It takes at least 5 seconds to upload one image (demo: https://youtu.be/laNmsiLhcFY), not due to upload speed but because imgur processing is slow.

@Mast you should consider all images uploaded to stack exchange over time and consider all the human time wasted. — Franck Dernoncourt 49 mins ago
@Mast I normally have the image on a third party site, so I just type the markdown and viola no upload to Imgur
I also noticed you on the outdoors meta about qpixel (IDK how it's spelt). Seems like they've actually got an MVP, just not in the language they want...
@Peilonrayz They've had a barebones MVP for Writing for a while now, and while it functions, I don't think it's close to what they had in mind yet.
Oh I don't remember Writing. I'm surprised at how far its come tho. But then again I'm judging it of the UI and their links/docs/pages whatever seem a bit lacking
2:43 PM
The problem of moving any community to anywhere is momentum. Whatever you come from has it, whatever you move to hasn't.
You can't 'migrate' a community like you can do with a server.
The neighbour's grass always looking greener until you buy the place doesn't help either.
Yeah, I can only see this fracturing the community, making two distinct communities. Or one if one disappears one day...

goto is hard to use correctly, but it is even harder to convince other programmers that you used it correctly. It will usually take less time to restructure the code than defend a goto in a code review. — user4581301 33 secs ago
@Mast Micro Soft Word does a fairly good job, but I tend to agree with you. The WYSIWYG would have to generate HTML, and CSS and maintain it to keep things correct.
And I hate cleaning up Word generated HTML.
@Peilonrayz You should see what it does to numbered outlines and table of contents if you think that is bad.
I don't use it, the worst I ever got was problems with images... I guess it was a blessing in disguise
Just think of the number of software engineers and programmers that MS keeps employed for that stuff.

As Emma said, this is better suited for Code Review, but I can already provide some feedback: You store the values as user Something but access them as something, so you get null. You should useprompt("something") instead of [prompt("something")]. The last one creates an array, which is probably something you don't want to do. Maybe you should handle if the user presses "Cancel". In that case, the return value of prompt() is null. — D. Pardal 45 secs ago
