Sprinting in DC

Planet SurreyLUG - Fri, 24/10/2014 - 18:17

For the last week I’ve been working with 230 other Ubuntu people in Washington, DC. We have sprints like this pretty frequently now and are a great way to collaborate and Get Things Done™ at high velocity.

This is the second sprint where we’ve invited some of the developers who are blazing a trail with our Core Apps project. Not everyone could make it to the sprint, and those who didn’t were certainly missed. These are people who give their own time to work on some of the featured and default apps on the Ubuntu Phone, and perhaps in the future on the converged desktop.

It’s been a busy week with discussion & planning punctuating intense hacking sessions. Once again I’m proud of the patience, professionalism and and hard work done by these guys working on bringing up our core apps project on a phone that hasn’t event shipped a single device yet!

We’ve spent much of the week discussing and resolving design issues, fixing performance bugs, crashers and platform integration issues, as well as the odd game of ‘Cards Against Humanity’ & ‘We Didn’t Playtest This At All’ in the bar afterwards.

Having 10 community developers in the same place as 200+ Canonical people accelerates things tremendously. Being able to go and sit with the SDK team allowed Robert Schroll to express his issues with the tools when developing Beru, the ebook reader. When Filippo Scognamiglio needed help with mouse and touch input, we could grab Florian Boucault and Daniel d’Andrada to provide tips. Having Renato Filho nearby to fix problems in Evolution Data Server allowed Kunal Parmar and Mihir Soni to resolve calendar issues. The list goes on.

All week we’ve been collaborating towards a common goal of high quality, beautiful, performant and stable applications for the phone today, and desktop of the future. It’s been an incredibly fun and productive week, and I’m a little sad to be heading home today. But I’m happy that we’ve had this time together to improve the free software we all care deeply about.

The relationships built up during these sprints will of course endure. We all exchange email addresses and IRC nicknames, so we can continue the conversation once the sprint is over. Development and meetings will continue beyond the sprint, in the virtual world of IRC, hangouts and mailing lists.

Steve Kemp: On writing test-cases and testsuites.

Planet HantsLUG - Wed, 22/10/2014 - 10:21

Last night I mostly patched my local copy of less to build and link against the PCRE regular expression library.

I've wanted to do that for a while, and reading Raymond Chen's blog post last night made me try it out.

The patch was small and pretty neat, and I'm familiar with GNU less having patched it in the past. But it doesn't contain tests.

Test cases are hard. Many programs, such as less, are used interactively which makes writing a scaffold hard. Other programs suffer from a similar fate - I'm not sure how you'd even test a web browser such as Firefox these days - mangleme would catch some things, eventually, but the interactive stuff? No clue.

In the past MySQL had a free set of test cases, but my memory is that Oracle locked them up. SQLite is famous for its decent test coverage. But off the top of my head I can't think of other things.

As a topical example there don't seem to be decent test-cases for either bash or openssl. If it compiles it works, more or less.

I did start writing some HTTP-server test cases a while back, but that was just to automate security attacks. e.g. Firing requests like:

GET /../../../etc/passwd HTTP/1.0 GET //....//....//....//etc/passwd HTTP/1.0 etc

(It's amazing how many toy HTTP server components included in projects and products don't have decent HTTP-servers.)

I could imagine that being vaguely useful, especially because it is testing the protocol-handling rather than a project-specific codebase.

Anyway, I'm thinking writing test cases for things is good, but struggling to think of a decent place to start. The project has to be:

  • Non-interactive.
  • Open source.
  • Widely used - to make it a useful contribution.
  • Not written in some fancy language.
  • Open to receiving submissions.

Comments welcome; but better yet why not think about the test-coverage of any of your own packages and projects...?

Steve Kemp: On the names we use in email

Planet HantsLUG - Sun, 19/10/2014 - 00:03

Yesterday I received a small rush of SPAM mails, all of which were 419 scams, and all of them sent by "Mrs Elizabeth PETERSEN".

It struck me that I can't think of ever receiving a legitimate mail from a "Mrs XXX [YYY]", but I was too busy to check.

Today I've done so. Of the 38,553 emails I've received during the month of October 2014 I've got a hell of a lot of mails with a From address including a "Mrs" prefix:

"Mrs.Clanzo Amaki" <marilobouabre14@yahoo.co.jp> "Mrs Sarah Mamadou"<investment@payment.com> "Mrs Abia Abrahim" <missfatimajinnah@yahoo.co.jp> "Mrs. Josie Wilson" <linn3_2008@yahoo.co.jp> "Mrs. Theresa Luis"<tomaslima@jorgelima.com>

There are thousands more. Not a single one of them was legitimate.

I have one false-positive when repeating the search for a Mr-prefix. I have one friend who has set his sender-address to "Mr Bob Smith", which always reads weirdly to me, but every single other email with a Mr-prefix was SPAM.

I'm not going to use this in any way, since I'm happy with my mail-filtering setup, but it was interesting observation.

Names are funny. My wife changed her surname post-marriage, but that was done largely on the basis that introducing herself as "Doctor Kemp" was simpler than "Doctor Foreign-Name", she'd certainly never introduce herself ever as Mrs Kemp.

Trivia: In Finnish the word for "Man" and "Husband" is the same (mies), but the word for "Woman" (nainen) is different than the word for "Wife" (vaimo).

Debian Bits: Help empower the Debian Outreach Program for Women

Planet HantsLUG - Thu, 16/10/2014 - 18:30

Debian is thrilled to participate in the 9th round of the GNOME FOSS Outreach Program. While OPW is similar to Google Summer of Code it has a winter session in addition to a summer session and is open to non-students.

Back at DebConf 14 several of us decided to volunteer because we want to increase diversity in Debian. Shortly thereafter the DPL announced Debian's participation in OPW 2014.

We have reached out to several corporate sponsors and are thrilled that so far Intel has agreed to fund an intern slot (in addition to the slot offered by the DPL)! While that makes two funded slots we have a third sponsor that has offered a challenge match: for each dollar donated by an individual to Debian the sponsor will donate another dollar for Debian OPW.

This is where we need your help! If we can raise $3,125 by October 22 that means we can mentor a third intern ($6,250). Please spread the word and donate today if you can at: http://debian.ch/opw2014/

If you'd like to participate as intern, the application deadline is the same (October 22nd). You can find out more on the Debian Wiki.

Steve Engledow (stilvoid): Things

Planet ALUG - Thu, 16/10/2014 - 01:05
Ogg(camp|tober|sford)

OggCamp was fantastic. If I can remember all the talks I went to I'll do a brief write up. The event certainly left me with a few little ideas for things to write and do.

Down with dynamic things!

One small example is that I've rewritten the build script for this blog. No more scripted generation of the final HTML; I just wget -m the development server and that's everything built. Then it's all just served up as static content through nginx. Simples and I don't know why I didn't think of just snapshotting it like that before.

Click

I've reached a point in my career now where I find myself wanting to create and present slide decks. WTF?

I'm still writing code fairly regularly but there's so much other stuff I spend my time doing that I'm not even sure I can account for. It still feels important.

Clock

I think I'm going to buy a Pebble to wean myself off the phone-checking habit that I've developed over the years.

Relatedly, I wrote this post on my phone. It wasn't nearly as painful as I'd expected.
