This post about kettles is strangely fascinating:
I actually did have people ask why I have a stove-top kettle back when I was in Ottawa. I usually said it was just habit (true) and I just didn't have space for another appliance (true) and then later when I wound up with a free electric kettle, I'd tell them that my electric kettle was terrifying (also true), but now I realize I could have said it was all about voltage and seemed *way* more into the science of my tea.
I'm doubting that all of us who use stove-top kettles actually thought about it that way, though. It's just what I was used to. I only switched a few months ago when an electric kettle was all I had while my stuff was in transit. And even if I'd cared, I might not have noticed a difference since water boils around 85°C here instead of 100°C (woo! Altitude helps protect me from burnt tongue!)
... all that said, I almost always boil water in the microwave now. 55s to hot chocolate!
To raise the temperature of one litre of water from 15°C to boiling at 100°C requires a little bit over 355 kilojoules of energy. An “average” kettle in the UK runs at about 2800 W and in the US at about 1500 W; if we assume that both kettles are 100% efficient† then a UK kettle supplying 2800 joules per second will take 127 seconds to boil and a US kettle supplying 1500 J/s will take 237 seconds, more than a minute and a half longer. This is such a problem that many households in the US still use an old-fashioned stove-top kettle.

Doctor Who Scarf: Finale
Apr. 13th, 2012 04:42 pmThe scarf is finished and gifted! As I said in the first post, I wanted to make the scarf for Ken because he's the one who's really carried me through the new seasons of Doctor Who with his enthusiasm, even when my faith in the writers often flagged.
I hope Ken enjoys it. I'm sad I didn't manage a better photo of him -- he's usually quite photogenic when I don't mess up the focus on my camera! It's soft and warm, so at least it'll do its job as a scarf. He agreed with my choice to prioritize softness over perfect colour matching, of course. Turns out Ken hasn't watched much of the old Doctor Who, though, so now he feels like maybe he should.
Quite a few other people have recognized and liked it, at least, including my mother. Tom Baker is the doctor that I remember watching sometimes as a kid 'cause he was the one my parents liked, so no surprise that she thought this was fun (if a little crazy). And of course John wants one too, but I think he should learn to knit one himself! He's good at this sort of thing and I like the idea of him messing with people's heads when they ask, "Oh, did Terri make that for you?" and he can say, "No, I did it myself!"
The best story I heard was from my friend Andrew, whose sister-in-law asked if she could knit him anything for Christmas and he said "a doctor who scarf" and she said ok without knowing what that was. When she found out, she had to retract the offer and told him he was getting gloves or something else manageable!
I say the scarf is finished because I've given it away, but if you look at the picture you can tell I only got this far in the scarf pattern:
Just over 70%, or I think around 8 feet long? I forgot to measure it. Obviously long enough for usual scarfy purposes. It's also slightly less wide than the pattern calls for because I thought it was hilarious if it was 42 stitches wide. If I were doing one for myself I think I might make it even less wide, although I *did* appreciate being able to use it as a blanket while I was knitting on the plane. ;)
I keep saying it took me around 3 weeks, but looking through my journal it turns out I started on Mar 22, so it's actually been closer to 2 weeks. 2 weeks + 2 days in fact. This was helped by the fact that I can knit at work during seminars, colloquia and other meetings (an extra 5-8 hours of knitting at work per week), but I also spent a lot more time than usual listening to audiobooks, the radio, podcasts, and even watching TV. It was fun -- often I get so bored/fidgety when i try to watch TV that I'll wind up doing things like getting up and cleaning just to avoid staying still (which is why I usually prefer audio-only media and am so hooked on the radio) but the knitting kept me busy enough that I could actually enjoy TV on my own while John was off at collab summit. I'm pretty impressed with myself regardless.
I'm most definitely not taking orders for any more dr who scarves anytime soon, but I might consider doing it again sometime just so I can say that I made a complete one. Right now, I'm trying to lay off the knitting for a bit I work on wrangling mentors and student applications for Google Summer of Code, but I'm finding that I've gotten so used to having my hands busy all the time that I'm craving a new project. Perhaps a smaller one this time, though!

I often get into discussions about whether people really do care about privacy, given that they give away personal information regularly when they share with friends via Facebook or other services. A recent report suggests that people do care, at least when it comes to banking and shopping:
The blog of the Office of the Canadian Privacy Commissioner (from which I drew this quote) sums it up in the title: Privacy: Not just good business, but good for business.
But I have to wonder, do these numbers indicate that privacy-preserving businesses will be winning customers, or will we simply see claims of privacy that aren't backed up by carefully constructed systems? Do consumers really care about privacy or do they just say they care? How will consumers evaluate potentially spurious privacy claims? In Canada we at least have the privacy commissioner who brings issues to light, and worldwide we have the Electronic Frontier Foundation, but while both organizations are astute and do their best, privacy claims are something that will need to be evaluated by organizations like Consumer Reports that are used by consumers when making decisions about where they spend and keep their money. Right now, by and large, we only hear about the relative privacy of an organization when a breach occurs.
I attended a talk on Internet voting yesterday and the speaker quoted an official in DC who claimed that, "voters like internet voting, so it must be secure," which is really quite a terrifying quote if you think about it. The speaker joked, "does this mean that because my kid likes cake, it must be healthy?" It really clearly demonstrates first that users of the system have very little understanding of its safety (despite strides in the area, internet voting as currently implemented is rarely secure) but also that officials who roll out such systems have little understanding of the flaws of the system and are much too willing to overlook them for convenience sake. If this is the case with voting, it's hard to believe that business would avoid such cognitive mistakes.

The Edelman study released in February 2012 shows that consumer concerns about data privacy and security are actively diminishing their trust in organizations. For instance, 92% listed data security and privacy as important considerations for financial institutions, but only 69% actually trusted financial institutions to adequately protect their personal information. An even sharper disconnect can be seen with online retailers, with 84% naming security of personal information as a priority but only 33% trusting online retailers to protect it.

16g USB necklace
Mar. 21st, 2012 07:13 pmI decided I wanted to upgrade my flash drive and there was no reason it shouldn't be pretty, so I bought this 16G USB Flash Drive
off Amazon.
It's so very shiny that when I opened it up, I decided that rather than just stuffing it into my purse, I should use it as a pendant. A few minutes, some jewelry wire, pliers, and a necklace wire I had on hand, and here it is:
I'm inordinately pleased with myself. :)
