You can buy a camera with an integrated thermal printer for 20$ or even less.

For a textual teaching language check out https://hedy.org It is multilingual (not just English) and introduces syntax gradually

I asked how much money people say they need to retire early.

In the answer:

> Median “target number” is about $401 k

So it thinks 401(k) means $401k :-)

These are Go bindings for Tk, a cross-platform widget toolkit initially developed as extension for Tcl. Nowadays a lot of languages have bindings for Tcl/Tk. Python for example has been including tkinter [0] for a long time.

If you look at https://www.watchrecon.com/ good get an idea what people spend on watches if they are into (collecting) watches

I find it strange that the README does not mention at that `eza` is a fork of `exa`.

Same here. I always had problems with laces getting undone. Not with this knot.

Looks like only some of the talks have a link to slides. The links visually blend into the other link in the title column.

[edit: some of the talks also can be found elsewhere when searching for the title]

I think this is a great idea and is super useful if you want to add annotations for a screenshot or overlay annotations in a screen sharing session

Using one of the many JS editors in something like codepen.io works well:

eg https://codepen.io/quill/full/KzZqZx or https://codepen.io/JessieWooten/full/wYObEX

Or one of the many online markdown editors (https://markdownlivepreview.com/, https://dillinger.io/)

You can use a different formatting. I would suggest looking at https://github.com/oculus42/short-uuid Of course if you just want a random ID, then you might not need a UUID. But UUIDs have the advantage that there are different versions and you can distinguish them; e.g. you might want a unique ID that gives you some debugging information (where/when was it created), so you use v1 and later you can decide to switch to v4 if decide you want the IDs to carry no information.

Indepedent of how you generate the ID, I think the base-57 encoding that shortUUIDs use is quite good when the IDs are user facing. Not using O,0,l,1,I in the alphabet makes IDs more readable.

I would probably see it more like low priority bugs in an issue tracker. They only get done when there's nothing with higher priority or someone takes a person personal interest.

Yes. Simplest in-place example would be bubble sort. You might need a temp element for swaps, but that's it. Heap sort can also be done with constant space. You need of course O(n) space to store the original data; but that is not part of the sort algorithm.

Sorry, wasn't clear. Was talking about the space complexity. If you sort in-place you don't need O(n) space, you can do with O(1 ). Not talking about time complexity
