For the typical case of a linear form over ${\mathbb{R}}^n$, the form can be seen just as a row vector with n elements, the full form being specified by the value of each of the basis vectors.

Namecoin examples are catalogued at: punycodes.xyz. The are small Unicode art or emoji code.

There seems to be nothing of particular artistic value as far as we've seen so far, the only interest in such tokens seems to be that:

This is one of the the key innovations of the Illumina (originally Solexa) sequencing.

This step is genius because sequencing is basically a signal-to-noise problem, as you are trying to observe individual tiny nucleotides mixed with billions of other tiny nucleotides.

With bridge amplification, we group some of the nucleotides together, and multiply the signal millions of times for that part of the DNA.

Simulates vintage hardware synthesizers, and includes some pretty complex ones!

Aims to show an UI that looks exactly like the synthesizers in question.

For example for the Minimoog on Ubuntu 20.04:

This is a really good piece of software. You can search on YouTube how some classic synths, work, and the immediately start playing them!

One of the defining properties of algebraic structure with two operations such as ring and field:This property shows how the two operations interact.

Some notable examples:

Example: sqlite/ip.c, adapted from www.sqlite.org/loadext.html, also mentioned explained at: stackoverflow.com/questions/7638238/sqlite-ip-address-storage/76520885#76520885.

Sample usage in the test program: sqlite/test.sh.

A slow development test cycle will kill your software.

New developers won't want to learn your project, because they would rather shoot themselves.

This means that build time, and the time to run tests, must be short.

5 seconds to rebuild is the maximum upper limit.

Of course, at some point software gets large enough that things won't fit anymore in 5 seconds. But then you must have either some kind of build caching, or options to do partial builds/tests that will bring things down to that 5 second mark.

You also have to spend some time profiling execution and build from scratch times.

A slow build from scratch will mean that your continuous integration costs a lot, money that could be invested in a new developer!

It also means that people won't bother to reproduce bugs on given commits, or bisect stuff.

One anecdote comes to mind. Ciro Santilli was trying to debug something, and more experience colleague came over.

To reproduce a problem, ciro was running one command, wait 5 seconds, run a second command, wait 5 seconds, run a third command:

The first thing the colleague said: join those three commands into one:And so, Ciro was enlightened.
