(I gave this talk at the Dutch Python meeting)
On the mailinglist, Remco Wendt asked for talks about making your practical development life more efficient. I recently cleaned up my mac, so my setup is nicely optimized again. And I know exactly where everything is, now. So I jumped in to give a talk.
My core tip: automate explicitly. Don’t just fool around. You’re bound to collect tips and tricks and snippets of bash configuration and small python scripts and so on. Don’t just dump it somewhere in your config file or on your path, but do it in a neat way. Make sure it is version controlled, otherwise it might just as well not exist. You move to a fresh laptop and you’re reduced to searching for old mails from colleagues to get your hands on that handy bash script again… So: collect everything, but be explicit about it.
I have a
~/tools/bin/ directory on my path. It is on github:
https://github.com/reinout/tools, including a reasonable README in case you
want to browse what I’ve collected.
Small shell scripts, many just one or two lines. For instance
editexternals that just does
svn propedit svn:externals . or an
svngrep that greps while omitting
.svn directories and
Custom-made Python scripts for specific tasks.
And a pip
requirements.txt file that lists a couple of external Python
packages that I want to install. There’s some nice stuff out there!
checkoutmanager (see later in this presentation).
Dotfiles is handy. Your home directory is full of configuration files and
directories that start with a dot (so: hidden files).
.profile. Dotfiles allows you to keep all those files in
one version-controlled directory with symlinks in your homedir. It is a simple
single-purpose script that works really well.
Comments about version control. I’ve got lots of code on github,
bitbucket, Plone’s svn repository and other public places. But… my dotfiles,
for instance, sometimes contain passwords. FTP accounts, pypi plaintext
password… I don’t want that on github :-) Luckily I have my own small linux
server (together with my brother, hosted at
bytemark). So I can put private repositories
on my server. SSH access is enough.
All those checkouts… I have 31 git, 22 svn and 9 mercurial checkouts right
now. No way I’m going to do a
git pull or
svn up on each of them every
morning. By hand. No way. So I wrote checkoutmanager to make my life
checkoutmanager up does
hg pull -u and
pull on every one of my checkouts.
checkoutmanager st shows me which
files are uncommitted in each of ‘em. And, important for distributed version
checkoutmanager out reports which commits haven’t been pushed to
the server yet. This makes sure you don’t forget anything. Very handy.
A small note on backups. Automation is fine, but you also need to feel safe. So automate this, too. Timemachine on OSX is handy. I’ve set up Ubuntu One for backup and sync for my wife’s and kids’ laptops. Works fine, too. Lots of my stuff is in git/hg/svn, so that’s automatically backed up. The mail is in IMAP in gmail’s clutches and with a copy on my own server. For backup tasks on the server, look at backupninja. The name is a bit funny, but it works real well. Easy to set up for various backup tasks. (Bytemark, where we have the server, have off-site rsync backup space for every account: handy).
Opmerking voor nederlandstaligen: we hebben weer een vacature bij Nelen & Schuurmans , waar ik werk. Iemand die kan programmeren maar die het liefst ook in de richting van projectmanagement en/of ontwerp wil kijken. Hartje Utrecht.
