A very simple tool for transferring files between two computers. Linux Windows should just work, uPnP handling, etc - just a crazy simple way to transfer a file without setting up Dropbox, ftp servers or whatnot!

Setup SCP on your windows box, everything else already "just works".

I would like (and pay some small amount) for a nice easy small webinterface to configure and manage samba on a little debian vm, something like the Synology UI has, but only for samba.

I know about Webmin as well as lots of other weird (outdated) gui's. I also am aware about the Xigmanas and nas4free projects. They serve lots of purposes at once and i'd like one just for samba.

A tool that checks your broken python/pip install and fixes it properly. https://xkcd.com/1987/

I don't think it's possible if you use a global environment for everything, as different packages might have conflicting dependencies. The best way to solve it is to separate environments. I personally prefer conda as it's fairly easy to create environments of any python version.

I wish I had a tool which measures the trend of every line code in my codebase in production, and shows me on IDE on the background of each line of code which code is mostly used (dark green background or such) and which code is barely used (in light green), and in gray unused code in production (based on the trend of last few months. The benefits : - I will understand during development which code is mission critica…

The tooling for this exits and is 100% usable. All you have to do is run a build with coverage enabled and then load the coverage data files into your IDE. At least Eclipse (with EclEmma) shows the results in a way that are pretty close to what you described. I'm sure other IDEs can do the same. The only thing is that nobody does this on production, because of the performance impact and potentially increased risk.

Yes. I know it's existing as coverage when you run unit-tests.

I'm well aware of the performance impact on production, I guess it's the major challenge here.

Since I'm mainly developing in python - here's a good article about that, he gave some directions to make it faster: https://www.drmaciver.com/2017/09/python-coverage-could-be-f...

The issue I face is that the TV volume suddenly increases when they start playing advertisements on TV. It is probably done to attract user's attention, but it is very annoying esp. for old people. I wished that there was some way (maybe an app on the phone) that will automatically control volume level at a set limit. The phones already have a way to measure decibals (sound meter app) and also a way to control audio…

At least in the US it is illegal for TV (that is, real television, not streaming) to play ads louder than the regular programming (and has been in the last decade). So that app could also auto fill the FCC complaint form[1].

Meanwhile, some TVs and audio receivers have a "night mode" that limits the maximum decibels. It's designed to not wake other people in the household up, but it also serves your purpose.

A better man page reader (man tool) allowing to: - show a table of content with a key press - jump to next section with a key press (like what woman does in emacs) - on a given flag, generate examples using that flag gathered from like GitHub

Regarding your last point, do have a look at utilities like these [1][2][3] if you haven't seen them before - I have just been using cheat.sh as no install is needed, and I think it pulls from the other 2 services.

Just set up a bash alias to simplify querying it.

A very simple tool for transferring files between two computers. Linux Windows should just work, uPnP handling, etc - just a crazy simple way to transfer a file without setting up Dropbox, ftp servers or whatnot!

For files that are not private I use: https://btorrent.xyz/ People usually recommend https://file.pizza but it just doesn't work for me. Now that I think about this it would be beautiful if there was something like stunnel but for NAT hole punching and what not. You would do: $ send-file FILE qk11c14pmq7maeod $ You would send the unique id (that could be also something that gives a QR code to scan or something like r…

You're looking for croc or magic-wormhole.

Software that enables me to cue and play out video and image output to a projector, without playback controls, the Windows UI, or Windows sounds getting in the way. And which enables me to quickly flick off to a black screen. Closest I've come is VLC with a split video interface in full screen, but it isn't perfect.

There are a bunch of video DJ suites out there that can do way more than what you need but they all cost about $300. There is an open source software called Snowmix that might do what you want. Interestingly, the project is run by an amateur manned space program.
