Q: S3Zilla - A GUI/Tkinter based file-transfer program coded in Python

m.a.d.catHere's the repository. It uses the S3 API to transfer files. Multiple files can be selected for upload/download. The windows version is basically the same except for some of the Tkinter widget sizing. Enjoy! #! /usr/bin/python3 from tkinter import * from tkinter.filedialog import askdirectory ...

Firstly, this is more a code review question. Second your code is "chopped" so much that it would be difficult for anyone to make sensible suggestions. — Peter 43 secs ago

Can you define "more efficient"? If this code basically works, it might be a better fit for Code Review SE, but be sure to read on topic first. — ggorlen 7 secs ago

HunterI am trying to send data from an Arduino into Python via USB every 100 ms. What improvements can be made to my code?

Hi ! Anyone here ?
Usually, yes.
I have a little program I wrote that I would like to post here, but I'm not sure it is acceptable
it is all in french (variable name and comment), should I translate before posting it ?
It helps with getting answers to post code that's in English, but it's not a requirement. One of the answers to your question would probably indicate that it's better to code in English since that makes it easier to share your code with others.
Ok thank you :)
The other question is about size : the project has 9 files/ approx 1000 lines in total... Can I post all of it, or should I just post the important part (main classes, tricky part I had trouble with ?)
8:05 AM
@sayanel You can include only the important part, as long sufficient context is provided . If the provided code calls some method that's not included, your question might be considered off-topic.
@Mast Are there any other tag combo's that require to be tagged together other than python-x-* / python? For instance, should Bash and Powershell also be linked to Shell?
@sayanel 1000 lines shouldn't be a problem. We have a character limit of a bit over 65k and I doubt your question (including code with accompanying text/description) is going over that.
@dfhwze If there's spare room, why not.

Thanks @ggorlen for your explanations about your code review. I was wondering if I want to put a second input for the text, how can show it under the first line. Because I tried with creating variables like ``` var userInput2 = document.getElementById("user-input2"); [...] var text2 = userInput2.value; ``` But I want a different font and a different size for this one, so variable textSizePx won't work for the second input. Even fillText() won't work for the second input. By the way, sorry for my messy code. I will improve myself. — ParkerIndustries 6 secs ago

When a chat-discussion becomes no-longer needed (e.g. post is updated in response) I always delete my comments and then flag the other parties' as no-longer-needed. Is this the right thing to do? Would it be better to just flag the other parties, and let the mod workout that it should all be deleted when they can see the whole context? (is it more effort for a mod to work out what has happened when half the discussion disappears, or to work out which other comments need deleting as well?)
Now that I think about it, should I flag all no-longer needed comments, or just the first? (normally I would flag the first of each 'conversation')

@VisualMelon If all comments should be deleted, use a custom flag to indicate as such on either a comment or the question.
Some moderators prefer that over flagging them all as obsolete one-by-one.
It has something to do with how they pop-up in their system.
OK, so they don't mind reading my ill-formed English? I assumed it would be easier to flag as not-needed, since they will presumably have to figure out the context anyway, but I'll try to remember to write an actual explanation in future.
@VisualMelon Messages I've used in the past go like: "All 3 comments are obsolete."
11:33 AM
@VisualMelon From Could we have some consensus on how to flag bunches of obsolete comments? on Meta Stack Exchange: “Use a custom flag when all comments on a post are obsolete.”
@VisualMelon I've posted a question asking this before, you can delete your comments as mods can see deleted commets, if you only flag the other persons your flags could stay. But I remember a mod saying to Custom Flag the post to nuke them all like Mast and Martin have said

for what it's worth: the more sorting out you do for us, the easier it is for us.
so if everything's unneeded you can flag every comment one by one (which is tedious), or use an "other" flag
otherwise cleaning up after yourself is something you can do, but don't need to
flagging your own comments isn't a thing in the interface IIRC
Having read the linked documents, I get the impression that "delete your own and flag everything else" is generally deemed a good idea, unless there are many comments, in which case a custom flag is in order.
yea, that about sums it up
Also, if you're asking how to improve working code, then perhaps this is perhaps better posted on the Stack Exchange Code Review site, but before doing this, you will also want to read the Code-Review help site, especially its How to Ask link. — Hovercraft Full Of Eels just now

Mmm you're smart @Vogel612 :)
I'm working on something for OGame and I want to spend X units on my defenses and I do that with a ratio of RL:LL:HL:Gauss:Ion:Plasma of 10:10:3:2:2:1
how do I figure out what to build
Mm, actually, if I divide everything by the most expensive unit then I get a ratio of 1:1:0.3:0.2:0.2:0.1
I can take the units value of those added together, and then divide my units I want to spend by that value
I think I solved it already :)

We have been doing this in C: // don't review char a[100]; fgets(a, 100, STDIN); The problem is that the array doesn't know how many...
