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.

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

> a sorting algorithm may take O(n log(n)) runtime which is pretty common but be able to operate on an array in-place, only requiring O(n) storage.

If it's in-place the sorting might only require constant space and it can be O(1 ) [edit: in terms of space complexity]

This is "made by a Googler"; that is not the same as "Made by Google".

  This is not an official Google product, it is just code that happens to be owned by Google

Worth noting "rows read" is not "rows returned". If you do 1000 full table scans on table with a million rows, you got a billion reads

vim had an undo tree for 10 years (or longer?) [0] and there are plugins (eg [1]) that make it very easy to go back in history and also to explore different branches of your undo/edit history. Dura will not track changes that are not saved to disk IIUC

Answering my own question...

From looking at https://gitlab.science.ru.nl/clean-and-itasks/clean-ide/-/co...

  - Clean used to be dual licensed: commercial license + LGPL
  - 3 years ago LGPL was replaced by Simplified BSD
  - 7 months ago the commercial license was removed

IIRC I looked at Clean 10+ years ago and it was not BSD licensed; either closed source or some restrictive license. And that made me not invest any time into trying it out.

Do I remember this correctly? Does anyone know/remember?

You are missing a '0' at the end of your first link.
