Compiled bjoern packages

bjoern is a WSGI-compatible web server for Python web applications. It supports both Python 2 and Python 3. Unfortunately the authors don't provide any binary packages but I've created compiled binary wheels for bjoern for Python 2 and 3 for Debian Jessie, Stretch and Buster and Ubuntu Xenial, Trusty and Bionic.

To install the package:

Debian packages for netatalk 3

netatalk hasn't been packaged with Debian for a few years now. If you don't want to get your hands dirty with compiling the package you can download compiled (binary) deb packages of netatalk version 3 from my GitHub releases. Right now I have packages for netatalk version 3.1.12 and 3.1.11 for for Debian buster, stretch and jessie.

To install the packages:

Tokyo

I had the desire to go to Japan, and especially Tokyo, because I wanted to spend my next trip in an urban area doing urban things. I felt that the last few vacations had a focus on exploring nature and natural wonders and I wanted to try going the other way. Tokyo is a massive urbanized area with the largest urban population in the world and endless things to do so it fit my goals well.

My criticism of dotdrop, a dotfile management system

Git, the command-line version control system, was initially released on April 7, 2005. Github launched to the public on April 10, 2008 and was the killer application that promoted Git beyond its initial audience of systems programmers. By 2010 it was clear to me that the industry was moving away from Subversion and Git was the new standard in version control. I took it upon myself to git with the times and learn it for myself.

Lessons learned porting from SQL Server to SQLite

After a sudden reduction in force at the day job I inherited a crufty old reporting system from a team of DBAs. We're a company full of Linux and a few legacy Solaris systems but the DBAs who built this thing almost 15 years ago must have insisted on SQL Server 2005 so I was the proud owner of one of the few Windows servers on our side of the business. After three months of wrangling with the report I was able to get it off of the Microsoft stack just before the Windows sysadmins decided it was time to pull the plug on this long forgotten and neglected Windows Server 2003 system.

Understanding the Lightning Network: how it works and why it sucks

Bitcoin engineers face a future where rising transaction fees price users out of using bitcoin for everyday commerce. There are a few solutions for lowering those fees and the latest, most hyped solution is the Lightning Network, a system built on a web of payment channels. I'll explain how payment channels work, how they can be put together to make the Lightning Network and show what this new economy looks like.
