Interesting to read about Jonas's Google Day.

At the BBC we have what's called 10% time, which in our team translates to a Gold Card Day every sprint (i.e. one day in ten, which is... um... 10%).

"Gold Card", because we do Scrum and we put a card on the board for each developer. With the card we can do whatever we want for a day, but it's supposed to be somewhat related to the product, the project, or the team.

It's really good if it's also Innovative(tm).

Innovation is what the BBC is after. Apparently this is even in the BBC charter, and it's something that all of BBC is supposed to be doing. Currently I know of our team and another department doing it, but it's something they are semi-actively trying to get going all over the place at the moment.

When we started doing this Gold Card thing, it turned out that almost no-one actually took his Gold Card during scrum in the morning. So after a couple of weeks our Scrum Master instated the one "mandatory" day of do-whatever-you-want, which worked out very well. It's at the beginning of the sprint, so we don't risk putting it off at the end of the sprint because things may not be done (if that happens, we need to plan and estimate the sprints better).

So what kind of things are we talking about?

• I spent last Gold Card creating a visualization of our code base as a clickable Treemap (I may turn that into a CPAN module in my own time. And replace that somewhat ugly JavaScript treemap with a prettier one). The Perl code stats collected so far are very naive, but here are some sample treemaps of our CPAN deps directory:
  • File Size
    
  • Line Length
    
  • Indentation
    
  • Indentation per Line
    
  • Sub Count
    
  
  
• Way way back I wrote a tool to document and visualize database schemas. As a Gold Card task a month ago I adjusted the tool to MySQL and configured it for our code base so we get an automated SQL Map generated whenever the schema changes.
  
  
• And the sprint before that, I spent Gold Card day investigating how Devel::Cover worked (yes, that took a day, more than that actually), making it possible to write Devel::CoverX::Covered and integrate it into Emacs with PerlySense (Ovid wrote Vim bindings).
  

While I tend to focus on tools and the dev environment and stuff like that, my team mates have investigated interesting and potentially useful technologies and done cool things to and with the product.

Edit: Added links to treemaps

When I run gnokii --monitor I get back Network: ..., LAC: 8bd8, CellID: 166e. This should be enough information to place me on the globe with the precision of between 3-30km. What's stopping me from compiling a table of lat-long values vs. LAC+CI in Israel (like the gsmloc.org guy, who's site I find creepy)? I'm guessing that the cell tower companies keep those tables secret and license the data at exorbitant prices. To protect that interest, they might play games with the CI values. I have no idea if this is done in Israel, but I'll check periodically.

Git has sometimes been described as a versioning file-system which happens to support the underlying notions of version control. And while most people do simply use Git as a version control system, it remains true that it can be used for other tasks as well.

For example, if you ever need to store mutating data in a series of snapshots, Git may be just what you need. It’s fast, efficient, and offers a large array of command-line tools for examining and mutating the resulting data store.

To support this kind of usage – for the upcoming purpose of maintaining issue tracking data in a Git repository – I’ve created a Python class that wraps Git as a basic shelve object. Here is how you normally use the standard shelve module:

import shelve

data = shelve.open('data.db')

# data.db may or may not have existed on disk before now.  If not,
# We're Manipulating an Empty Dictionary.  If so, we can examine or
# modify the previous run's state data.  In both cases, the database
# is manipulated like a standard Python dictionary.

data[key] = "Hello, world!"
data.sync()        # Write out changes to the dictionary

del data[key]
data.close()       # Close and clean up, sync'ing only if necessary

This provides the simplest kind of database, without any query language or notion of whether previous state did or did not exist. Both of those are services you’d have to layer on top of the shelve object if you wanted them.

Now consider gitshelve. Whereas the Python shelve module stores your data by pickling all of the dictionary values, I pass whatever data you place in the dictionary straight on to Git’s standard input. In the default mode, this means you work strictly with string data:

import gitshelve

data = gitshelve.open(repository = '/tmp/data.git')

data[key] = "Hello, world!"
Data.Sync()                  # Repository is created if it doesn't exist

del data[key]
data.close()

The interface is identical, but with the Git version you can now examine the resulting repository’s yourself, using regular Git commands:

$ GIT_DIR=/tmp/data.git git log

By default, the commits have no associated comment text, but the sync method doesn’t accept parameters. If you wish to add transaction notes, use the commit method instead:

data.commit("This is a comment")

You can store data this way either in a separate repository, or in named branches within any repository. If the repository argument is not given, the named branch within the current Git repository is used. An exception will be raised, however, if you do this and there is no Git repository related to the current directory.

# I'm expecting to use the 'data' branch of the current repository, but
# I ran the script in a directory unknown to Git!
data = gitshelve.open(branch = 'data')

# It appears to work, because no Git commands are run until the last
# possible moment
data['foo/bar/hello.txt'] = "Hello!"

# This raises an exception, because there is no current repository.  To fix
# it, either run "git init", or use a specific 'repository' argument above.
data.commit("I just said hello")

The really nice thing about using Git this way is that you get all of its best features for free.

Added non-text values

If you have a need to store non-textual values, you’ll have to let gitshelve know how to deal with them. I don’t do any such handling by default, because of the big chance of doing the wrong thing, and having you not find out about it until it’s much too late. Just pickling data like shelve does isn’t very smart, for example, because it will wreak havoc on Git’s merge algorithms should you ever need to incorporate new data from another source.

So, let’s see how to add a custom data translator. First, you need to subclass a new type of gitbook, which is the wrapper used to interface with the blobs in the Git repository. There are only two methods you need to override:

class my_gitbook(gitshelve.gitbook):
    def serialize_data(self, data):
        return object_to_string(data)

    def deserialize_data(self, data):
        return object_from_string(data)

Now you must define object_to_string and object_from_string, which should examine the types of the objects passed and turn them into merge-friendly string as appropriate. Certain forms of XML work well for this job, as do ini-style configuration files in some cases. It’s up to you and what works best for your usage.

Once you have this new class type, you must pass it to the gitshelve.open function:

data = gitshelve.open(repository = '/tmp/foo', book_type = my_gitbook)

Making things even faster

Every time you open a gitshelve, it must walk through the assoicated branch and determine its contents in order to build the key/value relationships in the dictionary. If you find that this ever gets slow, what you can do is just pickle the gitshelve! The only caveat is that you must take care to delete it if the HEAD you created it from is different from the current HEAD. Here’s an example:

import gitshelve
import cPickle
import os

data = None
if os.path.isfile('data.cache'):
    fd = open('data.cache', 'rb')
    data = cPickle.load(fd)

    # I'm using an arbitrary file name here, __HEAD__
    if data['__HEAD__'] != data.current_head():
        data = None       # Out of date, we can't use it

if not data:
    data = gitshelve.open(branch = 'data')
    data['__HEAD__'] = data.current_head()

# ... for data sets with enormous quantities of tiny files, this
#     could really speed things up ...

Where can you get it?

The gitshelve module is being maintained as part of the git-issue project, which is yet another attempt to bring distributed bug tracking to Git. Actually, I tend to support multiple repositories as data backends, but right now Git is my initial focus. You can clone the project and test it out as such:

git clone git://github.com/jwiegley/git-issues.git
cd git-issues
python t_gitshelve.py

If see “OK” at the end of the unit tests, you’re good to go! There isn’t much documentation on gitshelve.py itself right now, beyond this blog entry, but then again the shelve-like interface is simple enough that you really shouldn’t need much more.

Or if you prefer, you can just browse the project at the GitHub project page.

WARNING I needed a place to take notes while debugging sound issues after upgrading my desktop from Gutsy to Hardy, so here they are. This is probably a pretty boring read, so continue at your own risk.

Upgraded to Hardy today. Got some indistinct error message at the end, so I made sure and ran aptitude update && aptitude -y full-upgrade && dpkg --configure -a a few times before and after rebooting. Then, when I fired up Firefox (fired up... Firefox... get it...?) and went to youtube I realized I didn't have flash anymore. I aptitude installed flashplugin-nonfree, restarted Firefox, and videos worked. Yay!

Then I went away for a while. When I came back youtube videos had no sound. This is actually a problem that I was having before the upgrade. Not even a reboot helped. I fired up Amarok to see if mp3s still played. Nope, it froze. I googled a bit and found some pulse audio help which led me to believe that maybe I needed to add myself to the pulse audio groups. I did so, tried Amarok again, and the whole system froze. No magic keys or anything could save me. I hit the reset button on my case, and when it came back up, still no youtube sound. I started Amarok and it took forever to start, and then I made sure it was configured to use pulseaudio for its output plugin (I'm using the xine engine), and it didn't freeze, but it didn't play music either. Frustrating. First I had sound problems with Gutsy, and now seemingly worse problems with Hardy. Ubuntu, you've been so good to me in the past. What gives?

Pressing on, I tried changing the output plugin for Amarok and the whole app froze again. I tried watching video with totem, no sound. It froze after a bit too and I had to kill it. This is getting quite scary.

Reading some more here and here I discover this thing called libflashsupport. Aptitude tells me it's not installed and the description reads:

Due to various bugs in the Flash 9 plugin sound output of Flash 9 through the pulseaudio soundserver doesn't work properly. This library adds a clutch to make Flash 9 sound output in pulseaudio possible.

After installing this I shut off my computer completely (I'm in full belt-and-suspenders paranoia mode now), waited a few seconds and then turned it back on.

Taking a more conservative route this time, I started Totem first. No KDE or flash weirdness there. It worked, sound and video played without any problems. Next I tried Amarok with the xine engine output plugin set to autodetect. It worked, no hang. Next, youtube. No sound. Totem and Amarok still worked even after trying flash. I don't know if this result is any different from before, unfortunately. Maybe everything works better as long as you don't do flash first. I don't know.

I'm not sure what to try next. Apparently there might be a newer version of libflashsupport that I could try. This advice is not well explained, but it might be worth a try as well. Overall, I'm getting the impression that this is more the fault of flash than anyone else. Cursed closed-source crap!

I decided to try compiling libflashsupport from source as suggested on the pulse audio wiki. I aptitude removed libflashsupport first. After compiling and installing and restarting firefox there was still no youtube sound. Amarok and Totem were still good though. I rebooted. Still no youtube sound.

And then I saw it. There is a volume control on the little video controls under the youtube video. And it was turned all the way down. Oh. my. gosh. Sure enough, when I turned it up, sound played. How long has that been the problem!?!?!?

I decided to undo what I'd done a bit. I uninstalled libflashsupport as compiled from source and re-installed the ubuntu package. After restarting Firefox youtube and totem both worked, at the same time even. I think I'll leave things like that for now. Don't you love Linux? I do. I really do.

Adapting the GNU userland tools (and Debian package management) to the core system of a free software version of Solaris is called Nexenta. I used Solaris in university and learned a lot of unix and X window things while using it. I don't have any particular use for it, as I've only worked in situations where people could only afford GNU/Linux, and never had an legacy Solaris systems. Clearly, keeping GNU software highly portable has reaped many rewards for the day other kernels besides Linux became free software.

So I've been working on modularizing a big project at work. The REST API for this one project needs to be used in multiple places, so I've taken it out of the Rails app and spun it off into its own server using Rack. Rack is a library that abstracts away the gory details of HTTP and gives you a nice object-oriented wrapper for it, allowing you to plug it into multiple different backends. It's great for accelerating development on your simple lightweight services that wouldn't otherwise justify a Merb or Rails application. Ezra gives a good explanation of why you might be interested in Rack.

Anyhow, I was able to put this together fairly quickly by hooking up libxml, ActiveRecord, and Rack. (If I were doing it again I'd use faster-builder, which I found out about a few hours after I started the project, but whatever.) But this particular project must be able to support ridiculously large XML responses that could be larger than 4GB. On a 32-bit machine this is... well... problematic. The solution, of course, is to stream the response back to the client as it's generated so it doesn't have to all be in memory at once.

Unfortunately the only Ruby support for HTTP streaming I was able to find by searching the web is about streaming static files. I was getting pretty discouraged until Ezra mentioned that Merb bundles a patched version of Rack that allows streaming of programmatic content.

Sure enough, Merb's changes to Rack do the trick:

require 'rubygems'
require 'rack/response'
require 'rack/handler/mongrel'

# Launches an HTTP server on http://localhost:9999/N that streams its own code N times
Rack::Handler::Mongrel.run(Proc.new do |env|
                             [200, {}, Proc.new do |response|
                                response.send_status_no_connection_close('')
                                response.send_header
                                env['PATH_INFO'][/(\d+)/].to_i.times do
                                  response.write File.read(__FILE__) + '\n'; sleep 1
                                end
                                response.write '\r\n\r\n'
                              end]
                           end, :Port => 9999)

I check the streaming with curl; if it's properly streamed the % Received will climb slowly instead of jumping at once to 100:

$ curl http://localhost:9999/7 > /dev/null
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  5310    0  5310    0     0    755      0 --:--:--  0:00:07 --:--:--   796

It's not clear to me why this functionality isn't in the standard Rack distribution. Merb seems to be Rack's biggest user, so the fact that they have to bundle their own patched version seemes quite odd. Anyway, if you need HTTP streaming outside Merb, you can use my version of Rack. I haven't been able to get the gem served by Github; unreproducible remote problems in the gem build process are very opaque and give no feedback. Will look into this later.

I'm going to try to get the changes into the mainline rack, but if Merb hasn't been able to get it accepted this may not actually happen. The meat of the patch is three lines, but I've got a bunch of other stuff that allows the project to actually build as a gem; the source as I found it was not in a working state. (Who knew there were people out there who haven't yet discovered hoe?)

Much thanks to Ezra for the fix. I was starting to lose hope that I'd even be able to even pull this off without resorting to low-level Mongrel invocations. Even though the fix is available in Merb, it's not really very clear how to use it, so I thought this post would save other people from going through the same crazy hoops I had to.

In a previous post I discussed the undelete feature of version 2 of extended file system for the Linux kernel (ext2) and how it doesn't exist in version 3 (ext3). Someone asked in a comment about ext4. I found this in the frequently asked questions on the Ext4 project Wiki.:

Can I undelete files in Ext4?

No, in the same way that the ext3 journal requirements to be consistent after a crash prevent undelete of ext3 files, it isn't possible to undelete ext4 files.

However, the page with the list of New ext4 features has:

Undelete Feature for Ext4

• Primary Developer:
• status: Idea was proposed on the mailing list, still need more thought on the feature.
• Change on-disk format:
• Target Date:
• e2fsprogs changes:
• outstanding issues: Should the kernel be involved with undelete

I found this thread on the Ext4 mailing list archives Secure Deletion and Trash-Bin Support for Ext4. Apparently, people wanting secure deletion have something in common with people losing their files. I couldn't find anything further as to the patches status in ext4.

"So you're saying that to truly enjoy the car I have to break the law?" I say. But I understand Duncan's frustration. I'm an annoyingly cautious driver. The speedometer of this Aston Martin goes up to 220mph, and I haven't once exceeded 70mph.

"OK, I'll overtake that lorry. But just this once." I gingerly touch the accelerator. "Oh my God!" I yell.

I'm suddenly going 100mph and the car is so smooth it feels like 30. I've never seen a lorry vanish so quickly in my rear-view mirror. I feel like Han Solo in hyperdrive, or Jeremy Clarkson. It feels fantastic. No wonder the rich and boorish love themselves.

As I was reporting the details of my travails on #olpc, I noticed two nicks with "sj". I cracked a joke about the Jesuits being interested in the XO, only to be told that they (Boston College is in the neighbourhood) had in fact demo'd the laptop at the Vatican (at which point I solemly vowed that was the last Jesuit joke I was going to make.)

Then, to answer someone's question about Jesuits, I posted a link to the eponymous Wikipedia article and as I was browsing it, I noticed that a scifi novel, The Sparrow by Mary Doria Russell, featured a Jesuit priest (Brad Pitt has bought rights to the novel and is planning to play the priest in the movie). Strangely, there is no mention of Dan Simmon's novel, Hyperion, which also features a Jesuit.

Finally, the entry for The Sparrow has a link to the entire text of Arthur C. Clarke's short-story, The Star which features a similar plot.

This tip comes form the gnus mailing list from almost two years ago. I re-discover it today because, after writing a long email for a mailing list, I needed to change my original reply to a wide reply.

This is as easy as this:

Keybinding: `C-c C-f w'

Description: Insert `To' and `Cc' headers as if you were doing a wide reply even if the message was not made for a wide reply first.

The link for the original message is here

A couple of handy tips for those coding in C with Emacs. The first bit of code automatically saves all open buffers (ideally, it should only save source-code buffers) and starts the compilation process in one shot; the function, save-and-compile-program can be bound to a single key to speed-up the process:

 ;;; save all files then run M-x compile (defun save-and-compile-program() "Save any unsaved buffers and compile" (interactive) (save-some-buffers t) (compile "make -k")) ;;; bind it to a key-sequence (or an F-key) (global-set-key "\C-cc" 'save-and-compile-program) 

The next tip is helpful for those time when you have your source buffers arranged in a certain way and the compilation-buffer decides to whimsically re-arrange them; the library compile-frame comes in handy because it puts the *Compilation* buffer into a separate frame ("separate window" in modern terminology) leaving your buffer arrangement alone.

Both these tips were used for many years to make Emacs a more agreeable development environment.

A posting from earlier this year by Karl Fogel called Thread Theory explains how electronic conversation -- email, newsgroups, forums -- are all the same thing, threads.

This reminds me of something an old roommate had discovered 2 or 3 years ago when he was loving electronic fora -- Gmane, mailing lists, Usenet, blogs. He was also developing Web course software as a project for a software assignment for school. I think his quote was, "'You want a mailing list? That's a newsgroup. You want a Web forum? That's a newsgroup. You want a blog. Yeah, that's just a newsgroup.'" Needless to say, his group's Web course software design dropped the usual boring SQL database in favor of interacting with a Usenet server on the backend.

Los Alamos Computers is now selling laptops, desktops and servers preinstalled with gNewSense, the fully free GNU/Linux distribution. This is even better than what larger companies like Dell and Lenovo have been offering -- and they are also donating a portion of their sales to the Free Software Foundation.

I've been working with them to get this set up so I'm happy to see it go live. Especially since I'll probably be needing to make some purchases in the next year or so :).

I understand people who know each other following each other. That’s like RSS, right?

I don’t quite get how Twitter spam is supposed to work. Assuming some idiot start following me – how does that help them? Perhaps I click on their feed which is essentially full of ads and follow a link elsewhere? Perhaps.

What I also don’t get is apparent interests starting to follow me. What is @emacs doing following me? Is it a person? A name stealer? A topic? Something communal? Do we have shared ownership?

Weirdness.
