Speeding up bzr info on the hpss with a good sized branch - samba 4.0 (which is > 200MB of bzr repository).

I say 'whoot' to the sprinters!

So we've been sprinting here in Amsterdam all week. So far we've:

• created a prototype of windows explorer integration for bzr-gtk
• overhauled the commit, branch, push gui commands
• enabled plugins to import other plugins as-needed, allowing code sharing between plugins
• improved the smart-server branches performance for revno ~900% - and potentially an unlimited improvement as it no longer needs to read the entire revision-history file
• made good strides towards push in bzr-svn
• worked on the shallow branches spec - checking out or branching from a repository without having to read ALL of history
• more that I can't remember :).

So, phone call today went something like this

• Hello Robert [voice I dont recognise]
• Hi, who is this.
• This is a courtesy call from Telstra mobile, is that ok?
• Maybe, what do you want?
• Are you aware that Telstra a running a special right now - 400 dollars credit and a BRAND NEW PHONE absolutely FREE if you bring your number over to Telstra today?
• Are, so you are calling me unsolicted even though I'm not a customer of yours?
• <starts to say something>
• Let me make this clear, <shouting>FUCK OFF</shouting>
• dead phone..

Yeah, I was seriously cranky - after the amount of email spam I cleaned out this morning, it was -not- a good day to be spamming my mobile phone number.

I feel somewhat guilty about the abusive (its not my normal persona!) language to the poor shmuck (who sounded like they come from an Indian call centre by accent) whose job it is to spam people, but not very: they are willing to do so - so I dont feel guilty.

I do feel quite a sense of satisfaction though : imagine having one of the pharma spammers on the phone - what would you choose to say to them ?

Added to my list of 'things we need'... a version of icheck that requires less configuration to hook into package builds. Ideally one that we can get running automatically on any package build.

Yes, its sci-fi, but avoiding ABI breaks across all libraries would be fantastic.

Well, UDS mountain view is over, and all-hands.

I found the USA fun in a number of ways. However, for some reason I recieved the 'SSSS' ("Selected for Secondary Security Screening") marker on my boarding pass in both directions, which is known to not be a coincidence. So someone out there with my name is a security risk, or its because I flew from .au to .us on a .nz passport or perhaps they think I'm this guy.

I think its time we did something about this. I urge every American to start writing to your senator or representative about this.. Bruce Schneier and others have already commented on how ineffective the SSSS mechanism is.

For my part, I'm now boycotting as much as possible every company based in the USA. And I shall never visit the USA except when work compels me to.

Which is of course a shame, as many of the people in the USA are nice: but unless they collectively *do something* and fix their out of control government, the USA is heading into being a surveillance state.

Just landed a sweet feature for bzr: dotted decimal revision numbers. There is a sample log (warning its 2Mb) where you can see this in all its glory. A sneak preview is here:

This is really nice for users, because it lets them address revisions in a somewhat more predictable manner than the UUID each revision has. This feature is in the mainline now, look for bzr 0.12 to be able to use it - or grab bzr.dev now!

It make be a small thing, but barriers to entry are .. barriers to entry.

Erlang has a make-life file built into the system. If you see something like 'Emakefile', you might be tempted to google 'emake'.

Dont.

Instead, run 'erl -make'.

And this is my point : that should be made much more obvious. Simply saying in the README for an app that uses this, 'build with erl -make' would remove all the mystery.

Man, paper selection is awesomely hard... but we've done it!

My second release as bzr release manager is over - 0.11 is released. John A Meinel will be doing the 0.12 release - and it looks to be a cracker!

I've just released bzr 0.11rc2 which unbreaks the test suite for windows and fixes our commit performance regression! The 0.12 release will be managed by John Arbash Meinel, giving me some more cycles to focus on local performance. Yay!
