Learning Git, And Should You Switch from SVN

If you are just learning to use git, or you have been using it for a while without too much thinking, this introduction to Git principles provides a fantastic overview into the concepts behind git, using a very simple and natural examples. Do you need to switch to git from svn? My personal take on this is as follows:
  • If you have several developers far away with bad internet connection, then YES.
  • If you have more than several developers (say hundreds) then YES.
  • If your developers often work on long multi-day features, where they want to commit often, but commits may result in instability of their branch, then YES. Git allows much easier branching than SVN.
  • If you want to leverage GitHub's infrastructure for hosting your project privately or publicly, then YES.
To balance this and not to appear as I am advocating everyone to switch, here is the reverse:
  • If you have a small team who works locally and uses a local SVN server then NO.
  • If your team does not need branching, or prefers to check-in complete features instead of incremental check-ins then NO.
  • If your team is used to SVN and there are no major issues, then NO.
  • If your team is using SVN authorization module to create groups and grant them special access per subdirectory then NO. I am unaware of Git providing this level of access control.

Great post! I'd also say if you have more folks that don't know much about SSH or FTP, then ya, but there's git gui, so there's no excuse now.

Good point, thanks for sharing the link!

The real question is whether to switch to git or mercurial!

Car or Auto Make-Model-Year Database : For Breakfast

Make Model What?If you like me were tasked with loading a database of recent car makes/models/years, you would start by looking on the web and seeing if someone else just has it out there, readily available, hopefully for free, but perhaps for a tiny nominal fee.?If only it was that simple... I looked and looked, and couldn't find anything that would fit the above requirements. So I thought, who would know about US car models better than Kelly Blue Book? So I went on their site, and sure enough they have a javascript file that lists all known to them makes and models of used cars. Since the file is public, I figured it's not really "evil" if I scrape and parse it for my own benefit. Disagree? Have a better source? Then leave a comment.Anyway, to cut the long story short, I'm hoping to save a day or so to someone else who may, like me, be looking for this information. The ruby module shown below retrieves and parses the javascript from KBB site into a Ruby da…

Mac OS-X tips: How to run SSHD on an alternative port

This tip falls into one of those "I had to spend more than 10 minutes looking for an answer" category, so it's a worthwhile subject for a quick blog post. Why Run SSH? Running SSH on Mac OS-X allows you to login to your machine remotely, and also copy file securely via SCP command to and from your Mac OS-X host. But I am behind my own $50 router/firewall. Can I still connect to my computer from outiside?Yes. Most off the shelf routers and firewalls will allow you to do two things that are needed for this: Assign a permanent IP address to your Mac on a local network (see your router documentation for more details) Create a port forwarding rule on your router. Eg - any request to port 22 on your external IP (provided by your router) can be routed to the specific IP address of your Mac. Exact specifics on this configuration are once again available in your router documentation. Most off the shelf routers support this, including basic Netgear and D-Link. So let'…

Why I Like PostgreSQL

Today I gave a short presentation at work about PostgreSQL, and why I much prefer it to MySQL.

PostgreSQL vs MySQL: Eternal Battle
I may be misreading this, but it seems that there is a recent trend within startups to move away from MySQL, probably thanks to folks like Heroku on one side (who use PostgreSQL to the extreme, and help and contribute to it's development), vs folks like Oracle on the other side, tainting the "open source pureness" of MySQL :)

At my work we currently use a mid-sized MySQL 5.1 Percona instance, which is holding up quite well I must admit. Both PostgreSQL and MySQL have definitely converged to cover most features that people want, but my leaning is still towards PostgreSQL. I just agree with it's focus on data integrity, recovery, constraints, extensibility, while some of the early decisions in MySQL's design do not agree with me at all (like truncating long strings, 1/0 instead of booleans, ambiguous group by, etc). I think that data …
