OSSBarCamp this weekend

Published March 26, 2009

It’s two days until OSSBarCamp, a free open-source-focussed Bar Camp unconference at Kevin Street DIT, this Saturday. I’m looking forward to it — although unfortunately I missed the boat on giving a talk. (Unlike the traditional Bar Camp model, this is using a pre-booked talk system.)

Particularly if you’re working with open source in Ireland, you should come along!

I have high hopes for John Looney’s discussion of cloud computing and how it interacts with open source. Let’s hope he’s not too Google-biased in his definition of “cloud computing”. ;)

Also of interest — Fintan Boyle’s “An Introduction To Developing With Flex”. To be honest, I hadn’t even realised that Adobe Flex was now open source. cool.

Talk: Early days of Computing in Ireland

Published March 23, 2009

On Monday April 20th, the Heritage Society of Engineers Ireland, in association with The Irish Computer Society, and the ICT and Electronic and Electrical Divisions of Engineers Ireland, will be hosting an evening lecture: ‘Reminiscences of Early days of Computing in Ireland’:

In 1957 the Irish Sugar Company installed the first stored program computer in Ireland. Other large organisations slowly followed suit.

Gordon Clarke will discuss how the early computers enhanced the electro-mechanical systems that had developed over the previous 60 years. He will talk about their specifications, a few of the first applications and tell the story of the very early years of designing and developing computer based systems.

All Welcome. Admission Free. No booking required. This event will be web-cast

For Details: www.engineersireland.ie, or Con Kehely: (01) 6860113 (con.kehely /at/ dublincity.ie)

Location: Engineers Ireland, 22 Clyde Road D4

Sounds great! Thanks to Frank Duignan on the ILUG list for forwarding the notice.

4chan Memes, circa 1889

Published March 20, 2009

In the comments to this unremarkable story about 4chan’s Boxxy fad, I came across this gem from CSClark:

I don’t know why I didn’t think to see if this sort of phenomenon was covered in Extraordinary Popular Delusions… Of course, it is.

Walk where we will, we cannot help hearing from every side a phrase repeated with delight, and received with laughter, by men with hard hands and dirty faces, by saucy butcher lads and errand-boys, by loose women, by hackney coachmen, cabriolet-drivers, and idle fellows who loiter at the corners of streets. Not one utters this phrase without producing a laugh from all within hearing. It seems applicable to every circumstance, and is the universal answer to every question; in short, it is the favourite slang phrase of the day, a phrase that, while its brief season of popularity lasts, throws a dash of fun and frolicsomeness over the existence of squalid poverty and ill-requited labour, and gives them reason to laugh as well as their more fortunate fellows in a higher stage of society.

Wherein we also learn that the FAIL of the day was Quoz:

When a disputant was desirous of throwing a doubt upon the veracity of his opponent, and getting summarily rid of an argument which he could not overturn, he uttered the word Quoz, with a contemptuous curl of his lip, and an impatient shrug of his shoulders. The universal monosyllable conveyed all his meaning, and not only told his opponent that he lied, but that he erred egregiously if he thought that any one was such a nincompoop as to believe him.

I’m also sure I’ve read of a fad – Greek, Roman, 18th century, something like that – where a group of young (aristocratic?) men who would suddenly grab a common woman and proclaim her Helen and make her their queen and swear to die for her and so on. And the tearing down of such idols could be seen, if you were wont to be pretentious like me, as part of Frazer’s Golden Bough’s Sacrificial King idea, although I’m not sure script kiddies care if the crops grow. (One other problem with that is that Frazer was romancing; but so are the more literal memecists, so yah!)

Since then however, it appears that “quoz” has entirely flipped meaning, according to UrbanDictionary:

slang for quality, a cockney term for something good. usually accompanied with a hand action of slaping ur index finger against the stationary thumb and middle finger. ‘thats quoz man! propa quoz.’ finger slappy hand thingy

“Fundamentally flawed”

Published March 18, 2009

Killer presentation — “RPC And Its Offspring: Convenient, Yet Fundamentally Flawed” from Steve Vinoski, who presented it at QCon London last week. It’s full of reminders of the mid-90’s, hacking away on CORBA technology — Steve was one of the key players at Iona while I was there.

But never mind where we’ve been; let me hit you with the summary slide to show where Steve’s going:

  • RPC is a convenient but flawed accident of history

    • 1980s research focused on monoliths of programming languages, distributed applications, and operating systems
    • each computer vendor of the time owned their own full stack, from language to hardware and network, and you used what they gave you
    • imperative languages won back then simply because of their superior performance at that time

  • It’s almost 2010, folks — we can do WAY better

    • pull your head from the imperative language sand and learn functional programming
    • the world is many-core and highly distributed, and the old ways aren’t going to keep working much longer

Awesome ;)

A plug for Kiva.org

Published March 14, 2009

I just made a loan using Kiva.org to a weaver in Nepal and a group of Vietnamese broom makers.

You can go to Kiva’s website and lend to someone in the developing world who needs a loan for their business. Each loan has a picture of the entrepreneur, a description of their business and how they plan to use the loan so you know exactly how your money is being spent — and you get updates letting you know how the entrepreneur is going.

The best part is, when the entrepreneur pays back their loan you get your money back – and Kiva’s loans are managed by microfinance institutions on the ground who have a lot of experience doing this, so you can trust that your money is being handled responsibly.

Kiva’s microfinancing seems like a nice way of helping the developing world, and I’ve heard good things about it. Here’s hoping it works out well for my two recipients!

Google Reader productivity hack: change your Home

Published March 11, 2009

So, if you use Google Reader, read your news with the “All items” page, and are subscribed to hundreds of feeds, it can be pretty overwhelming. I’ve found a better way to deal with this.

Select a ‘most important’ subset of feeds. For each of those, click through to the feed details page, hit the “Feed Settings…” menu, and select “Change folders…“. Put the feed into a new “top” folder (creating it if necessary).

Now go to “Settings” -> “Preferences” and check out the “Start page” preference. By default, it’s set to “Home“; change it to “Folders and Tags: top“.

Hey presto — now, when you load Google Reader, it’ll come up with your “top” items. You can get through those quickly enough, and get on to other more important tasks. When you’re bored and need something to read, though, just hit “Navigation” -> “All items” (or even just type ‘ga’), and every other feed is now there for your delectation. Sweet!

Using VC to track system config changes by mail

Published March 3, 2009

Here’s a great idea from a thread on the SpamAssassin users list, from Roger Marquis:

Karsten Bräckelmann [questioning the utility of a mechanism to dump the entire contents of the SpamAssassin configuration database]:

‘postconf’ without the handy -n switch dumps about 500 lines. The equivalent dump for SA including the rules is about 6000 lines. And that’s a plain dump, without following and unfolding meta rules or anything.

Whether 6K or 60K would not necessarily make a difference to how I would like to use an SA ‘postconf -n’ equivalent. That use is change management. The intent is not in the full report itself but in its deltas.

As full time mail/systems admins we get invaluable data from tripwire/integrit, ‘postconf -n’, dconf, ‘rpm -qa’, ‘dpkg -l *’, ‘pkg_info -a’, … whose output is checked in to RCS daily. This provides a nice configuration snapshot and historical record but its real usefulness comes from rcsdiff piped into a daily report. These are (usually) relatively concise, and IMO, absolutely essential for monitoring production Unix/Linux systems.

I like it! I think I’d check it into a git repo, though. The concept of applying VC smarts to traditional sysadmin tasks is definitely a meme on the way up — see also etckeeper.
