Simon Rumble’s blog

Just discovered a really interesting food blog, STUDIOKITCHEN, written by chef Shola Olunloyo. It's got lots of cool technical experiments, and good ideas. Most interesting post I've found so far is this have you post, which just asks some simple questions about things you should try cooking.

Have You wrapped fish in Kombu and poached it gently. No I haven't but it sounds divine. I'll try it shortly I think. Fortunately I work above a large Asian supermarket.

Have you just for the heck of it made Miso Soup lately with Dashi and Bonito. No I haven't and it's insane that I haven't! Miso soup is one of the easiest and most delicious quick meals you can make. In fact, I think I'll make some tonight! I'm a big fan of (rehydrated, dried) Shiitake mushrooms in mine. And with the weather turning cool, there's nothing finer than a warming bowl of soup. Well, maybe a really hearty stew, but nothing finer for a weeknight.

Last night I knocked up a couple of changes to the shed plans, taking out the windows on the "shed" side and removing the door between the two sections to reinstate the separate doors. So we'll have a glass sliding door on the "office" side, and an ordinary external door on the "shed" side. There'll be loads of natural light and ventilation on the "office" side, and complete darkness on the "shed" side.

The purpose of all these changes is to finally get myself a meeting with the planners at Marrickville Council. I'll be asking lots of questions about the planning process and what I need to give them to get my Development Application through. We've got a few things that force us to go the DA route. The floor space of the "shed" is bigger than the "complying development" rules, and our house isn't detached so we can't use the new rules.

I'll have lots of technical questions for them too. Like the need for a retaining wall under the fence, as there's about a 50cm drop at the fence. And drainage is going to be an interesting issue, as the back of our block is lower than the street level. Big question is whether I can use a rubble pit for the gutters on the shed, or if I have to do the very complicated easement thing and drain into a public stormwater drain.

Over the weekend we made a few changes around the house. The hedge out the front came down, which means the front looks quite strange since we're accustomed to the hedge. I'm thinking of growing a lemon and lime tree out there now, but might change my mind and go for something deciduous to let light into the front room in Winter.

Also moved the Myth server into the lounge room, as I figured it's so quiet it might work out there. I'm not sure it'll end up staying there, as the hard drive can be quite noisy when it's in use. But using the Myth interface is brilliant, compared to the PS3. I can watch high def stuff, including downloaded video, without having to worry about the PS3's very finnicky format requirements. Ad skipping is just so wonderful for the few shows I watch from commercial telly.

I also measured up our house block and designed what I think is the eventual design I'll use for my garden lair. As featured on Shedworking last week I've been using Google Sketchup to design my lair. I'm pretty close now I think.

The shed is divided into two halves. One half is the more traditional "shed", with storage space and possibly a little bit of workshop space. I'll brew beer in here too, and if we have space put a chest freezer. The "office" side will be where I but my desk, computers and office space. It will have nice natural light access and shelves. The whole thing will be lined inside with plasterboard, well insulated (thermally and acoustically, as we live under the flightpath) and have a weatherboard skin. Roof will be Colourbond. There'll be a fair chunk of space inside the ceiling, which we'll also use for storage.

A couple of changes to the design you see above (click to see more angles) have come up. I think I'll skip windows in the "shed" half, to allow more wall-mounted storage. And the door between the two halves will go — I was thinking of putting a water tank in front of the "shed" half, but I think direct access to each half will be better.

I'm planning an office/shed in the garden of our house, to provide an office for me and storage for the household. I've been mulling over the design for quite a while and now need to finalise it and get plans into council. Above is my first draft which has windows in the space between horizontal and the sloping roof, similar to this building. The finish would be similar too, with either these kinds of boards or possibly weatherboard.

Yesterday while flicking through architecture books at Kinokunya yesterday I discovered these Gilbert Barker Pod buildings. I quite like this look too, particularly the way the glass frontage is recessed back from into the building. Angled the right way, this could be a passive solar element.

So any ideas on this shed? Inspiration to share? I have a whole gallery of inspirations. The actual space looks like this photo and we're looking at dimensions of about six metres by four metres. I hope to have a wall down the middle to separate the "office" and "shed" parts of my lair.

Having shamelessly stolen Danny's excellent research I've finally finished building my new quiet server for MythTV, Squeezecenter and other serverly duties. It's brilliant!

The Antec Mini P180 case and Antec NeoHE power supply provide the core noise reduction. The case is solid and with an enormous, but slow, fan at the top of the case providing quiet cooling. The mounts for all the drives have little silicone grommets to cushion their vibrations. Seems to work very well with my four 7200 RPM SATA drives, which previously resonated inside the case and made a very loud, high-pitched hum that was audible from the lounge room.

I don't yet have the CPU heatsink, as my supplier sent the Xeon version instead of the 775 socket version. The supplied Intel fan is bloody quiet anyway, only moving at 800 RPM. I'm sending the heatsink back and will see if they'll give me a refund instead of a replacement.

The result is that unless you put your head almost inside the cupboard, you can't hear the computer. This contrasts rather well with the previous systems, which had quite the roar going on. Cooling is okay, though I'm gonna have to keep an eye on it. Running two burnP6 processes sees the temperature (presumably CPU, but lm-sensors labels it core 0 when another is CPU temp) shoot up to 61 °. Perhaps that big mama heatsink will help there, as it's not the ambient temperature in the case that's the problem. See the graphs.

In fact it's so quiet I'm tempted to move it into the lounge room so that we can use the MythTV software for playback, rather than the PS3 which has plenty of problems with file formats (though has spectacularly good picture quality). If I can convince the boss of the merits, I might buy one of the more-appropriate HTPC cases and move all this hardware into it. Then I'll build myself a nice quiet desktop. I'm sure she'll claim this was my cunning plan all along...

I'm very happy with this system. Total cost around $650. Thanks for letting me steal your research Danny!

There's a bit of a furore over the costings of the Notional Broadband Network, with the Conservatives claiming $150 a month or more. I thought I'd do someback-of-the-envelope calculations.

Assumptions

Number of Australian households: 8,321,000 (projected for 2009, series 1 which was lowest)

Number of households covered: 7,488,900 (90% coverage, assuming they all take it up)

Ten year government bond rate: 4.605% (though I'm not sure I understand the terms "Coupon" and "Yield" here so using the lowest number)

Cost of NBN: $43,000,000,000

Calculations

So the interest on $43 billion is $1,980,150,000 per year. Divided by the number of households that's $264.41 per household per year, or $22.03 per month.

So without factoring in any payment of the principle, it looks a whole lot like the Telstra tax (line rental), which you must pay today to get xDSL-based broadband. Of course you'd need to pay back some of that money, or at least the half that isn't being stumped up by the government, at a commercial rate of return. But even doubling it to $44/month to give some payment of the principle and if you get a few services over it (phone, pay TV, broadband internet, smart electricity grid) that's still okay.

But part of this whole process is to preserve the competitive tension between the new NBN and existing ADSL1/2- and cable-based broadband services. Keeping the NBN honest, so to speak. So what happens if only half take it up? Well then we're looking at $38.25 a month per household, only paying off the interest.

Assuming more numeric minds than mine, who know the fudge factors for "commercial rate of return" and understand what bond rates are, it sounds like the Tory claim of $150/month upward would be at the wide end of the calculations (say your Internet provider was BigPond), but aren't out of this world.

The basic fact of the matter is that we shouldn't be expecting this thing to pay for itself directly. Roads don't, nor does any other infrastructure project. At best we should expect to pay the interest on the bonds, and make the project a gift to the people of Australia. The sooner the ALP has the honesty to say this (hell, did the Hoover Dam pay for itself?) the sooner they can shut down this attack on the project.

Here's my spreadsheet. Feel free to point out my mistakes.

After Jean Charles de Menezes was murdered by London police in 2005, you'd think the press would be more skeptical when the Police make claims. But no, when Ian Tomlinson was assaulted and, ultimately, murdered by London Police last week, the press reported "police were bombarded with bricks, bottles and planks of wood" as they assisted him.

The Guardian has video footage of the brutal Police assault that ultimately killed the man. He was walking away from the cops, back turned to them and with his hands in his pockets: not exactly threatening behaviour. A cop whacks him on the back of the legs with a truncheon, then pushed him to the ground where it appears he may have hit his head.

I've seen the brutality of these cops first hand, and seen the ridiculousness of their tactics. In my case they herded protestors into Oxford Circus and then held them there for hours without food, water or toilets. I fortunately was far enough back in the crowd to see what was happening and managed to stay out of the encirclement. I was threatened with arrest for taking photos of coppers who had removed their identification, and for asking for their numbers.

Pricks. Don't expect any justice for Ian Tomlinson, just like Jean Charles.

So we've finally got the non-announcement of the winner of the National Broadband Network tender, and the winner is... everybody loses! Thanks for playing kids.

So instead of awarding the tender to the best bidder, or bidders, they've decided to go it alone and do it themselves. Because the last time we had a government telecommunications monopoly, that worked great. Low prices, great innovation. Why I even recall being told that that government monpopoly wouldn't investigate data faults until they reduced throughput to 300 bits per second. (Though that scenario is eerily close to the privatised government monopoly's treatment of faults that affect anyone except Telstra retail customers.)

You might expect the tenderers, who put enormous effort into scoping and costing their proposals, might be a little pissed off. Particularly given the government set them the pretty well unachievable target of 98% coverage, while they've set themselves the much more sensible 90%, meaning the NBN will cover the cities and large regional centres only.

Worse yet, the person in charge of the whole proposal is someone who has spent the last 1.5 years alienating the entire telecommunications industry. A man so unable to understand his portfolio that he can't even explain his plans to filter the Internet without constantly contradicting his own statements, and reacting to any criticism by claiming his critics are child pornographers. I would have a lot more faith in this project if they put someone competent in charge. Someone of the Lindsay Tanner calibre, rather than talentless backroom numbers hacks.

Next interesting part will be whether or not Conroy releases the expert panel's recommendations. I suppose that depends on whether or not it agrees with the decision he's had made for him.

I've got a very bad feeling about this whole project. Governments have a very bad record in building technical infrastructure, and of managing giant projects in general. Anyone who's been around telecoms in Australia from before the privatisation of Telstra will remember the ISDN fiasco.

Back in 1998, Auckland had a major blackout lasting five weeks. Oh how we mainlanders laughed. The cause, we were all told: privatisation.

Now we've got regular blackouts here in Sydney. Oh how the East Islanders must be laughing. The solution? privatisation.

Now I thought I'd become suitably curmudgeonly with age, what with still using a text-mode email client and grumbling about HTML posts. But it's always good to know there's someone better at something than you. Gives you something to strive for.

Enter Tom Ellard's Soggy The Sailor rant. I bow before the master.
