MSP430 Alphanumeric Instructions
[0-9a-zA-Z]{2}
30-39,41-5a,61-7a
a:61 z:7a A:41 Z:5a 0:30 9:39
MSP430 alphanumeric shellcode is hard. There's no way to write to memory,
no word-sized reg-reg operations, and all we have is add/sub/mov and a few conditional jumps.

You appear to be creating a new IDE...
You appear to be advocating a new:
[ ] cloud-hosted [ ] locally installable [ ] web-based [ ] browser-based [ ] language-agnostic
[ ] language-specific IDE. Your IDE will not succeed. Here is why it will not succeed.
You appear to believe that:
[ ] Syntax highlighting is what makes programming difficult
[ ] Garbage collection is free
[ ] Computers have infinite memory

Simultaneous output to Analog and HDMI with Jack on Ubuntu 13.10

How to get simultaneous / dual output to both Analog out and HDMI out with Jack Audio on Ubuntu 13.10

Configuration used:

  • OS: Xubuntu (Ubuntu) 13.10 (saucy)
  • Audio: HDA Intel PCH (ALC269VB Analog) on an Intel Core i5 2557M (Sandy Bridge microarch)

Install below packages and set user group, then reboot

Packages you will need (and the versions I had when I did this):

  • jackd2, 1.9.9.5+20130622git7de15e7a-1
# mail.example.com should be one of the results of a `dig +short mx example.com`
# Note that your provider might block all port 25.
# If STARTTLS header is missing or mangled, but https://starttls.info/ shows example.com as supporting STARTTLS,
# there might be a downgrade going on.
(echo EHLO foo ; sleep 3) | nc mail.example.com 25

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.

How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would
