I learned Common Lisp with this book. I read other books, but this is easy to understand and well presented.

I wanted to see images also - no matter how crude they be.

Impressive, although quite large program! One suggestion: Use PgUp and Pgdown to scroll a screenful, and use arrow keys to scroll one or two lines. Use shift with some keys to scroll half screens. Is there a keyboard shortcut to go into rem

And then we should talk about categories (and subcategories, relations or associations) instead of tags, which to many people seem to represent a flat namespace of tags.

I got the idea for Spellbook, because I was learning programming, but also having some projects that involved quite a bit of research on subjects like audio physics, statistics, data visualisation etc., and I wished I could keep my bookmark

I also had the idea to apply these kind on ideas about nonhierarchical file organisation to music or photo library organisation, and really wish there was a file system level support.

The article fails to mention existence of graph databases or graph theory, except for tuple spaces which leads to that direction. Property graph model is the keywords to search for if you are interested in graph databases' suitability

I could not get Postgres installed through NixDarwin, so I installed with Postgres.app for MacOS. With it you can easily manage Postgres versions.

I have moved to Nix on two of my three machines – the two laptops have Archlinux32 and MacOS Mojave. I should replace Homebrew installed packages with Nix packages on my desktop iMac too, but in the mean time I have used Macports and some N

Nox is much easier interface to nix. I often use that instead of nix-env.

Nix with nix-direnv is awesome!

I was also interested about the data (and cryptanalysis on it) – the best I could find with a quick inquiry was the original article published in The Astrophysics Journal: https://iopscience.iop.org/article/10.3847&#x2F

An intuitive understanding or the mathematical formulas is that they describe an oscillating radius, which results in the various shapes as you move along the angle in polar coordinates.

I have used superellipses as oscillators. They look much better than rounded rectangles, and probably work with less and more equally spaced polygons in 3d. You can probably calculate the points as slices in azimuth, or as a continuous heli

With a PDF file you can also make the image crop box be exactly the reference image area, add crop marks and put the CC note and other info possibly inside or outside the crop area.

For anybody wondering – the correct DPI is about 508 for some reason.

by peterhil 5y ago
This seems very handy – however the reference image would be infinitely easier to print on the correct size if it was a PDF file. PNG image format does not retain the resolution IIRC.

This requires nix-direnv installed with Nix.

I wrote a handy wrapper for xlrd in 2014 while making my project Ninhursag. I just checked and it still works with Python 2 – here is an example usage: pip2 install excelsior curl -O https://prd-wret.s3.us-west-2.amazonaws.c

I have been using this setup for a few months now, and generally it works really nicely, except for clang_12 on Mojave and Python packages. When you combine direnv with shell.nix or default.nix by adding "use nix" in a `.envrc` fi

The specs for this game jam are quite loosely defined, but basically the point is to make a game or app in two weeks with fantasy console specs at 240 x 135 px resolution, 10 colour palette, 7 control buttons and TIA like audio capabitilies

No surprise. WD My Book was the worst purchase of my life. The dual RAID hard drive just started clicking one day, and no data could be read after that. Apparently using only one drive was not possible on hard drive failure or the controlle

Thank you for the kind feedback! I made an issue, and will fix that and other accessibility concerns in the next release: https://github.com/peterhil/ninhursag/issues/10
