yesterday i did a quick tally of my cycling this year, and it looks like i rode between 2700 and 4000km (26km 'standard trip', never less than twice a week but more commonly 3-4 times, all year round).

not too bad, considering my slacker nature...

The current wanking draft for HTML5, section translates into the W3C saying 'standards are a good thing, but we are clairvoyant and know better than all of you, so fuck them standards and all the people actually relying on standards compliance!'

Dear W3C, when I label material as being encoded in iso-8859-1 then I MEAN ISO-8859-1 and not smart-shite-infested windows-1252, thank you very much.

Your oh-so-helpful labelling of this mess a 'willful violation, motivated by a desire for compatibility' motivates me to shoot you all on sight.

I've got these Ikea spice racks in my kitchen, and the way I installed them they needed to be fastened to the wall for stability. I didn't want to drill the tiles, however.

Once again my answer is "recycling": I habitually salvage the magnets from dead hard drives. The spice rack is coated steel, the magnets are pretty strong and so I simply glued a bunch of them onto the tiles. Silicone sealant makes a decent glue for operations like that, and it's removable if need be. Problem solved.

...doesn't have to be high tech. I've got a new toy that I really like:


It's a Aristo 868 slide rule, and I find it pretty amazing how much you can do with it. Best of all: no batteries :-)

I'm obviously not against high tech, for example:


That's my trusty HP 28S, which I got in 1988 - RPN forever! But still there is a certain minimalistic appeal to the simple magic of sliding log scales...

I like gumtree quite a bit: it's free for private ads, no registration required, simple email-based access and best of all it works. When my nephew visited we needed a car seat for him, and the second ad I responded to worked out. Now that Emil is back in Vienna the seat is surplus. I posted an ad two days ago, had four responses within 24 hours and sold the seat today (for the same amount as I paid two months ago). Very nice.

I just hope ebay (who own gumtree via some subsidiary nowadays) don't stuff this service up...

One week ago: I detect a leaking hose under the bathroom wash basin. Fortunately it was only the fitting that needed to be screwed on a little tighter.

Sunday: the water filter (under-sink twin system, in the kitchen) is leaking badly. Repair attempts showed that the plastic filter housings had developed cracks and were about to start spraying water big-time.

Sunday, part 2: So I bunkered some 20l of filtered water in a plastic water bladder, just to tide me over until the filter was back in operation. However, the collapsible water canister has also suffered a puncture and leaked almost as badly as the filter.

Monday: I checked with the original supplier of the kit (7 years later, and the local company is still thriving, a good sign) and it turns out that the cheap filter housings that I ordered in 2004 should be replaced every 5 years or thereabouts. I ordered the (marginally pricier) premium housings on Tuesday, got them on Wednesday and all is well again.

I heartily endorse PSI Filters: they are local(-ish: Tasmanian), their prices are good, and their advice and customer service are great.

but then that's maybe a good thing? Because Tron = pretty cool for 1982, but Tron Guy = doubleplusuncool, anytime.

Recently I bought some pretty cheap LED strips (5050-type, 60 LEDs/meter, flexible, waterproof and self-adhesive, can be cut every 5cm, cost $72 for ten meters) for overhauling the under-cabinet lighting in the kitchen. One old laptop PSU went into the range hood casing (displacing the trashy light sockets that thing had) and the left side is powered by a low-profile LED transformer. Mounting the stuff is a breeze: cut to size, cut and peel back a little of the silicon waterproofing, solder on wires, then peel off the backing paper and stick it in place, done.

I think it looks great - I'm pretty sure my sisters will say it looks like an abattoir... It's certainly very nice for working and it's also pretty frugal for the amount of light (about 2A at 12V on the left side, a bit less on the right).

dear wikileaks webhamsters, would you please stop inflating every single damn cable with all the navigational fluff? it's all empty carbs, you know, and makes mirroring you a FPITA.

if you downloaded the latest cablegate snapshot via bittorrent you might be surprised that it's only about 300 megabytes (for 150k cables) - but you WILL be unpleasantly surprised when you unpack that archive: it expands (like kudzu) to a whopping 30+ gigabytes.

the reason: every single cable page is infested with links everywhere else and then some, so that the actual content is just about 3%.

take this cable for example: after ripping out all the gunk between <div class='pane small'> (might have called the css class 'pain, big') and the closing </div> after 'courage is contagious', the page shrinks from a whopping 168k to just 6k. the cleaned page thus consumes only 3.6% of the disk space and network bandwidth of the fugly original beast (and don't forget there's 150 thousand such occurrences right now).

nobody, dear leakers, is going to mirror 30+g of you strutting your fluff on a daily basis - but a decent, still navigatable 7g would be a very different story.

If you're situated somewhere near the Gold Coast and need a Unix/Linux sysadmin/netadmin/security person/software geek for some Unix-related magic, then you might like to know that I'm for hire (casual/hourly or long-term).

I'm likely not the cheapest around (cf. 'pay peanuts, get monkeys') but then I'm quite good at what I'm doing and have a fair amount of experience (22+ years various Unixes, C, Assembler, Lisp, 19+ years Linux, 15+ years Perl, 10+ years as Debian Developer - thus quite familiar with Debian and its derivatives like Ubuntu - and so on...)

Some time ago I wrote up my experiences with running gpg remotely. This post documents the most recent changes I've made to my setup, which finally make my gpg (and ssh) keys fully mobile and 'migratory'.

Like before I use the kernel key storage system to cache passphrases (and that won't change until I switch to gnupg2 with the agent). But now my keys are all stored on a usb stick, in an encrypted filesystem.

When I login the first time any day, I load the keys from the encrypted storage into a RAM disk. (A simple symlink in ~/.gnupg is sufficient to convince gnupg to find the secret ring.) When I leave for/from work I nuke the RAM disk - that way the keys are always only present where I physically am.

The big new change from the previous setup is that now I use sshfs when I need to use gpg for anything on a remote box: I ssh into the target box with a remote port forwarded back to a listening instance of sftp-server on the local box (which has the keys in RAM). With agent forwarding on, the sshfs connection doesn't require entering passwords, and the mount point is of course set to be the same as the RAM disk location for locally loaded keys, so to gpg it's totally transparent. (I'd never do any of this if not all machines in question were under my exclusive full control.)

sshfs is no speed daemon, but then the secret ring file isn't large. sshfs with -o directport on the forwarded port reuses the existing outbound ssh connection, so one single outbound ssh connection does it all - and another benefit of that setup is that the keys vanish from the remote machine as soon as the outbound ssh connection is shut down.

The one simple shell script doing all this setup is less than 60 lines long: simple, neat, sufficient.

What do you do with dead hard disks? I usually salvage the magnets; the larger ones make perfect holders for things like tools, knifes or mobiles.

Here's my ghetto mobile mount, mk.2: a 3x3cm piece of thin sheet metal sellotaped to the back of the phone and two fat ex-disk magnets screwed to the dashboard. Plenty strong, vibration-proof and completely invisible under the silicone phone cover. And, of course, zero cost.

her: that's great. please note that this call may be recorded or monitored for training and quality assurance purposes. are you ok with that?

me: no, i'm not. i do not want this call to be recorded.

her: brief pause while some thoughts scramble through her hamster brain, which is obviously completely lost when things leave the crib sheet path oh, but why do you not want that call recorded?

me: i do not want this call to be recorded.

her: but what's the problem?

me: i do not want this call to be recorded.

her: ok, i won't be able to continue this call then. have a good day. click

me: happy

Next time I think I'll ask for extra anchovies with my pizza (if male sales weasel) or request some telephone sex (if female).

Looks like some of my students think I'm a reincarnation of Werner Kuich - not because of any brilliance on my side but because of his really special first lectures which scared off a good number of prospective students (the subsequent lectures were then held at a quite humane speed and pretty good IMHO).

So a number of the more unwilling members of my flock decided to bail out early - which is of course their call (at the ork place they can switch subjects until end of week 2) - but it still rankles to have this kind of desertion just because you a) expect them to start working in week 1 (duh!), b) don't dumb down the content to the level of 'reading for dummies' and c) require that they allocate a few working brain cells to this here university education thing.

once more i got nice feedback from somebody out there who benefits from my tinkering - it's very nice to see that one's efforts aren't totally wasted.

here is the original post about pam_recent for context; the newest version (with documentation) is here.

lorenco catucci suggested that pam_recent works better for rate limiting services that don't terminate the network connection on a failed login if it offered handlers for the other pam phases too, most importantly auth.

that way, one can use pam_recent to record that somebody attempts access in an iptables' recent list, and clear the record if and only if the connection gets to the account or session stage. in this setup pam is providing the control and iptables recent match just enforces the limits.

nice idea, just a few simple changes required and the result is better and more useful than before.

..of those high-energy photons, please! Ahem. On Monday the sparkies performed the solar installation on my roof (6 big panels for a nominal 1.5kW of lovely solar electricity).

We'll see how much of my energy needs that will take care of (it won't be all for sure; I usually need about 11kW/day and a 1.5kW installation won't provide more than 60% of that) - but the feed in tariffs for exporting energy to the grid are good (so far): you get quite a bit more for your exported kW than you pay for consumption.

Now I just need to wire up the inverter's serial port and start logging performance with rrdtool...
