One thing that annoyed me a bit with Tcl is that tclsh doesn't come with readline support, meaning you can't go back to previous commands using the up arrow. However, you can work around that using rlwrap. alias tclsh=rlwrap

I a big fan of the way Bob Nystrom skips the LR and LL theory and goes straight to recursive descent parsing plus the precedence-climbing trick. I'm of the opinion that if you have to learn ONE thing about parsing then it should be how

What made Tcl click for me was thinking that it is basically shell/Bash, except that it's a coherent and sensible design. Just like an unix shell, everything is a string and you don't need to use "double" "quot

At least I'm glad that the press article included the actual images. Oftentimes we have to track the original paper to see that kind of thing.

The Lua benchmarks are a bit funny because many of them were tuned for LuaJIT, including tricks such as eval-based metaprogramming which work well in a JIT.

That's just "2nd ammendment" propaganda that he borrowed from the United States. It's patently clear that he'd go for a totalitarian takeover himself if he could. He just hasn't yet because he did not have the

One of the things that is different is the matter of Moral Rights such as the right to be attributed as the author of the copyrighted work. In some jurisdictions those rights cannot be waived. https://en.wikipedia.org/wiki&#

One of the sticking points is that some countries do not allow the author to waive the Moral Rights over a work that they have produced. https://opensource.stackexchange.com/questions/1371/how-can-...

In Germany a work can only enter the public domain after the copyright expires. The author is not allowed to waive their copyright and intentionally put their work in the public domain before that. If you want to make something available wi

Another thing is that the current world is more hostile to RNA. Anyone who has ever worked with RNA will tell you that you need to be very careful during the preparation to avoid contamination with ribonuclease enzymes that degrade RNA. We&

I hadn't thought about the search highjacking problem but it does help explain why Mozilla is intentionally making it harder to mess with the search engine settings. It does sound like an external program would be the only way to do it

Is there some way to add a big list of search keywords to Firefox without having to type them one by one in the settings screen? I've been trying to figure out how to do this for years now with no luck.

In many of these the full name is also a valid bang. For example: !wikipedia !youtube !twitter !steam !twitch.

I find that Zenity really shines if the script is intended to be launched outside of a terminal window. For example, I have a script bound to Super+Y that opens a youtube video inside a local video player. Before it starts the video it show

I think this might be what the author was trying to say with that inscrutable stack trace that they weaved between the various quotes. It would be reasonable to argue that all those FilterDefinition.doFilter are making it harder to debug th

On Linux I like using gitg. I think it is "good" in the sence that for the tasks it can do (mostly viewing history) the UI is well though out and simple to use. However, it can't do more advanced tasks so it might not be what

The Sun's tidal forces on Venus are only 2.6x the Sun's tidal forces on the Earth, which is less than the tidal forces we get from our moon. (This estimate assumes that tidal forces are proportional to 1/R^3 and that the orbi

I think it is different than CSS here. With CSS I could never really understand how it worked and each new browser released introduced new concepts that added more and more corner cases to the mix. On the other hand, with shell scripting af

I agree. Python shines when you can use real libraries such as "requests" and if you are able to use a proper string/regex manipulation instead of being forced to live with sed/cut/awk. However, sometimes I really j

Everything being a string is not that bad in a world of shell pipelines, where all the commands arguments and results are strings anyway. And if you want you can also use data structures like lists and dictionaries. It is a bit idiosyncrati

One of these days I'm going to write a blog post about it... The built in "exec" command supports pipelines and file redirections with the usual syntax so you can do exec foo < bar | baz and it works similarly to

Recently I've discovered that TCL is a very pleasant language for shell scripting. The command-based syntax and the "everything is a string" design are a perfect fit for that problem domain. Next time that you have a shell sc

It is possible to use Lua hooks to protect against programs that accidentally take too long too run. Lua can be told to stop the script after so many steps. This technique isn't fool proof against maliciously crafted programs, but it m
