  GPU-based Onion Hash generator

Nitpick about the website, but please don't use PGP short fingerprints like 0x46EBCD72F08E6717. They can be brute forced [0] very fast to get a different private key with the same fingerprint. You can also use them to generate keys with vanity fingerprints, which is pretty funny [1].

• libmish

  Libmish adds a command prompt to your program, and telnet access. With your own commands.

I use a similar approach in libmish [0], ie I "reserve" the bottom 2 rows, and output the scrolling text in the top parts. Pretty straightforward.

• npm

  48 17,233 2.1 JavaScript

npm was about 6 years old and im pretty sure a lot of corporates have adopted node by then.

I don't think it has so much to do with quality but rather we like to re-invent shiny "new" wheels and then the new tooling must iron out all the corner cases.

• runSAS

  1 9 0.0 Shell

  This shell script tool allows you to run a SAS program or a batch of SAS programs via Bash environment with various interactive and non-interactive execution modes. This is ideal for a SAS environment which is restrictive by design and you need a batch execution script/tool especially when you have a batch of SAS Data Integration Studio (DI) jobs.

I implemented something like this in pure bash. I called this status bar sort of implementation as "message bar" to show ongoing progress when script is running on the bottom of the screen using just bash...

This message bar would also become a prompt and take in user inputs on certain events apart from being a static status bar

Cursor positions, scrolling screens, event handling, progress bar, resolution changes, user inputs...everything had to be catered for in this - I remember thoroughly enjoying developing this.

  Composite Radial Progress Demo

To take things in a more constructive direction, that said, it is an area I've experimented with/tried to solve.

My big idea was radial progress indicators to try a different "best of both worlds" approach to progress spinners versus progress bars especially for "composite" progress indication where you have an unknown number of subtasks all running at their own speeds and can be discovered/initiated independently (such as downloading files). People are worse at estimating percentages of circles than lines, which I see as something of a benefit (because the exact progress percentage should be fuzzy).

It's still not great at giving an indication of overall speed/estimated time, but it's potentially very great at "the application hasn't crashed and is busy".

It was fun to experiment with/prototype, but I don't expect it to replace progress bars any time soon. (I think it should, but it's trade-off space where every option has drawbacks and while it fits closer to what I think is my personal "ideal", it probably won't make everyone happy either.)
