tig + mutt = commit review
I spend some of my time reviewing team members commits. Typically I’d use the RSS feed from Google Reader, but it doesn’t have the actual diff to comment on.
Most of the time I use tig to view
the commits. And instinctively I’d want to email the author with my comments, so here’s how to do that. I’m sure there are easier commands but this is what worked for me, your experience may vary.
First thing I did was create a git alias which is useful by itself. It outputs the commit to a temp file, then gets the title and the author’s email address from the same commit passing that to mutt.
[alias]
...
prepmail = !sh -c 'git show $1 > /tmp/commit && mutt -s \"`git show --pretty=format:\"%s\" $1 | head -n 1`\" -i /tmp/commit -- \"`git show --pretty=format:\"%ae\" $1 | head -n 1`\"' -
Now I want to be able to press a key in tig at the diff screen to reply to the author’s commit.
Simply bind a key, in my case I bound s in the diff view to call git prepmail with the commit’s SHA1.
In your $HOME/.tigrc add the following line. Checkout the tigrc man page for more information.
bind diff s !git prepmail %(commit)
Now in the diff view press ‘s’ and tig will launch mutt with the appropriate information.
The email shows up first:
Followed by the email’s subject, notice it matches the commit’s message.
And finally, the diff as an email body allowing you to comment on the changes
to the author.
So a simple git alias in $HOME/.gitconfig, a key binding for $HOME/.tigrc, and you can now review commits using tig. Enjoy!

can I have a do over?
The next webapp I write, I think I’m going with some of the new hotness: NoSQL datastore, RESTful API, and Ruby. On a recent project I chose to use a RESTful API which I really like, but it definitely changes how you think of things coming from the XML-RPC way of doing APIs, but I still like its simplicity.
Unfortunately, I went with Java as the implementation instead of something like python or Ruby, and looking back I don’t know why I did that. I should know by now that python and Ruby are much easier to work with than Java has proven to. Hell even the build environment is a pain: ant – write xml build file from scratch, maven – reminds me of make with lot’s of pom.xml files, or buildr – ruby based maven replacement, annoys all Java people. If I had a do over on this I’d choose Ruby as the implementation language.
Since we’re using Java and needed a database we went with Hibernate. If I had to redo this decision, I most certainly would’ve gone with a NoSQL datastore like MongoDB or CouchDB, this way I could avoid the annoying mapping of domain model to relational tables which is highly annoying.
So if you’re planning a new webapp avoid the boring, traditional webapp design of using a relational database with ORM and compiled languages 
To C or Ruby that is the question :)
I’m trying to decide whether to pick up C again (as it’s been almost 13 years since I’ve done it) or Ruby. I’ve spent the last 13 years in the Java world, as of late I’ve been working with python as much as humanly possible. Ruby keeps me in the web side of things, but C would open up a bunch of Linux opportunities which I find interesting. I know one of my friends would say neither go for Erlang
</thinking>
sm-photo-tool bug fix release – 1.19
sm-photo-tool had a problem where it would no longer upload pictures to your smugmug.com account, a bug of this magnitude pretty much renders a photo uploader useless I fixed the upload issue and at the same time switched it from using a HTTP POST with multipart encoded data to HTTP PUT. Uploads are now FASTER!

Evil Robot Conference (no robots allowed)
On Saturday, I attended the Evil Robot Conference held at Red Hat HQ.
I got there a bit late, but I caught the tail end of Clinton Ebadi’s talk on “UnCommon Web: A Common Lisp Tale of Continuations, Multimethods,
Metaclasses, and Web Applications”. While Lisp can be hard to understand, what you can do with it from a web programming perspective made Java webapps look quite lame considering the amount of code you have to write to make them do anything.
Had lunch at El Cerro with Kevin Smith, from Hypothetical Labs, and a few other folks attending the conference. A good time was had by all, and the salsa was quite spicy but oh so good today
After lunch, I sat through Dan DeMaggio’s “Anti-databases (NoSQL): Where they came from and where they’re going”. I learned a lot of alternatives to the old school single database setup. There’s a lot of cool stuff out there for this such as redis, Cassandra, couchdb, BigTable.
Dan’s talk was followed by Kevin’s “Intro to Erlang” which was most excellent as well. Kevin seemed very comfortable talking and definitely knows his stuff. Great job!
Last but not least, I got to hear what BRTFS was from Josef Bacik. Very cool stuff, most of the time I forget how much cool stuff goes into OS development compared to the webapps I do for a living.
All in all, it was a great day long conference. I hope we can make it at least a yearly event.
PS. Sorry I missed your talk Max and thanks for the donuts.
