Bitcoin is a money platform with many APIs

Bitcoin is a money platform with many APIs

Bitcoin is much more than just a digital currency. It is a protocol, a network, a currency and a transaction language. Most of all, though, it is an application programming interface (API) for money. Nowadays, bathroom scales and fridges have APIs, so why not money?

Traditional money does have APIs, but they are closed. You can program the merchant API of the VISA network if you are a trusted merchant. You can send and receive FIX messages if you are a stockbroker or exchange. Regular people, however, don’t even have APIs into their bank accounts, let alone the broader economy. Bitcoin changes all that by not only offering an API for accounts (wallets) and transactions, but also making that API available to everyone.

Fedora for short-lifespan server instances

Fedora for short-lifespan server instances

Let’s come back to the odd fact that Fedora is both a precursor to RHEL, and yet almost never used in production as a server OS. I think this is going to change. In a world where instances are deployed constantly, instances are born and die but the herd lives on. Once everyone has their infrastructure encoded into a configuration management system, Fedora’s short release cycle becomes much less of a burden. If I have service foo deployed on a Fedora X instance, I willnever be upgrading that instance. Instead I’ll be provisioning a new Fedora X+1 instance to run the foo service, start it, and throw the old instance in the proverbial bitbucket once the new one works.

The Archive of Interesting Code

The Archive of Interesting Code

The Archive of Interesting Code is an (ambitious) effort on my part to research, intuit, and code up every interesting algorithm and data structure ever invented. In doing so, I hope both to learn the mathematical techniques that power these technologies and to improve my skills as a programmer.

VaultPress Lite

VaultPress Lite

VaultPress, “the world’s best WordPress security, backup and support”, has recently introduced a Lite plan.  It’s only $5 per month and it covers most of the essentials:

  • Daily backups that happen automatically, so you can focus on creating, not logistics.
  • Automated site restores, so you can restore your entire site with a single click.
  • Thirty days of saved backups, so you can go back in time to restore the last clean version of your site.

It’s cheap enough for small, personal blogs, and it’s more than perfect for start-ups and small businesses too.  $60 per year for healthy full night sleep is nothing in my book.
