One Speaker Per Child (OSPC) project.

-
100 speakers. One for each person at a party.

Here's six mini usb sound cards attached to some usb hubs and extension cables.



The plan is to hook up 100 speakers to 50 sound cards attached to a bunch of linux computers connected via the network. Then using the OSC protocol to get them to act as one massive speaker system.

The cool thing is that there'll also be 50 microphone inputs.

I'm not sure what kind of limits I'll run into yet. It'll be interesting to see how many sound cards I can attach to each computer. Hopefully all 50 sound cards on one computer!

For fun. For arts sake.

So I can observe how people interact with lots of different speakers :)

So musicians have a chance to play music from 100 different sources. Kind of like an orchestra, or a big band might sound like.

Draft 3 of, ^Let's write a unit test!^

-

So, I started writing this for people who want to 'contribute' to Community projects, and also Free Libre or Open source projects. Maybe you'd like to get involved, but are unsure of where to begin? Follow along with this tutorial, and peek at the end in the "what is a git for?" section for explanations of what some of the words mean. Draft 1, 2018/07/18 - initial draft. Draft 2, 2019/11/04 - two full unit test examples, assertions, making a pull request, use python 3 unittest substring search, "good first issue" is a thing now. Started "What is a git for? Jargon" section. Draft 3, 2020/12/12 - default branch name is main. What's first? A test is first. A unit test is a piece of code which tests one thing works well in isolation from other parts of software. In this guide, I'm going to explain how to write one using the standard python unittest module, for the pygame game library. You can apply this advice to most python pr

Is PostgreSQL good enough?

-

tldr; you can do jobs, queues, real time change feeds, time series, object store, document store, full text search with PostgreSQL. How to, pros/cons, rough performance and complexity levels are all discussed. Many sources and relevant documentation is linked to. Your database is first. But can PostgreSQL be second? Web/app projects these days often have many distributed parts. It's not uncommon for groups to use the right tool for the job. The right tools are often something like the choice below. Redis for queuing, and caching. Elastic Search for searching, and log stash. Influxdb or RRD for timeseries. S3 for an object store. PostgreSQL for relational data with constraints, and validation via schemas. Celery for job queues. Kafka for a buffer of queues or stream processing. Exception logging with PostgreSQL (perhaps using Sentry) KDB for low latency analytics on your column oriented data. Mongo/ZODB for storing documents JSON (or mangodb for /dev/null replacemen

post modern C tooling - draft 6

Contemporary C tooling for making higher quality C, faster or more safely. DRAFT 0 - 10/11/18,  DRAFT 1 - 9/16/19, 7:19 PM, I'm still working on this, but it's already useful and I'd like some feedback - so I decided to share it early. DRAFT 2 - 10/1/19, mostly additions to static analysis tools. DRAFT 3 - 10/4/19, updates on build systems, package management, and complexity analysis.  DRAFT 4 - 10/6/19, run time dynamic verification and instrumentation, sanitizers (asan/ubsan/etc), performance tools, static analyzers. DRAFT 5 - C interpreter(s).  DRAFT 6 - 11/6/19 , mention TermDebug vim,  more windows debugging tools, C drawing for intro. In 2001 or so people started using the phrase "Modern C++". So now that it's 2019, I guess we're in the post modern era? Anyway, this isn't a post about C++ code, but some of this information applies there too. No logo, but it's used everywhere. Welcome to the post modern era. S
