TiddlyWiki for Technical Talks?

One of the most interesting talks that many of us in the quantum computing world have seen is the talk by Manny Knill on fault-tolerant quantum computing. Above and beyond the interesting content, what was cool about this talk was that, as far as I could tell Knill used a linked PDF for the talk. That way if he needed to delve into deeper details on a particular subject, he could. While for some talks, like colloquiums, I don’t see the need for this, for technical talks before a more informal audience, this, I think is a great tool. Now, having discovered TiddlyWiki, I wonder if it isn’t time for me to try to perform a similar feat but using TiddlyWiki? Hmm, I have very tempted.

Leaving Academia: Cry or Celebrate?

No, no, I’m not leaving academia (yet 🙂 Pfffffft! That’s the sound of me thumbing my nose at the world.) But recently I was thinking about about people who get a Ph.D. in, say, physics, or are a new postdoc, and then are faced with what to do next. As Peter Rhode, writes in a post today (or whatever day it is in the upside down part of the world) entitled “Farewell physics”:

The academic system has some serious problems. Most notably in my opinion, there is very limited scope for promotion. For every permanent position there are countless postdocs competing for that position. It simply isn’t possible for all of us post-docs to progress right up through the ladder. Many of us will be stuck as postdocs for the indefinite future. Realistically, I could expect to spend the next 5 or even 10 years as a post-doc before a permanent position would come along, and even then I would have very little control over where I would end up. I’ve seen many outstanding colleagues in exactly this position….
There is a huge salary discrepancy between academia and the private sector. With the same qualifications one can earn twice as much in the private sector than as a post-doc.

Peter, like others before him, has decided that the academic rat race is not the path he wants to take, and is therefore heading out for greener pastures. Of course my first reaction, I’ll admit, is one of sadness: I’ve read some papers by Dr. (err DJ) Rhode, and enjoyed them. By contributing to quantum information science, he’s become part of a community I consider myself a (annoying, loud, insert random invective here) member of. But, in thinking about this, I realized, that I’ve got it all wrong.

Black Hole Bets Of a Different Kind

So you really think the LHC is going to swallow up the Earth by creating a black hole or a quacking duck with X-ray super powers? Why don’t you put your money where your mouth is? Not to be confused with other famous black hole bets.

New CACM

The first edition of the newly revamped Communications of the ACM is out. And I must say, so far I’m greatly impressed. First of all it seems that they’ve gotten rid of the absolutely horrible front pages for all articles that were (a) ugly (I’m not a font nazi, but sheesh that font choice was horrible!), and (b) a waste of space. This issue includes a blurb about quantum computing, an interview with the Donald Knuth, and a paper by David Shaw (yeah, THAT David Shaw) and coworkers on custom hardware for molecular dynamics simulations. Good stuff, I hope they can keep it up!

Blak Holz Eatn My Worlsd! Update

Woke Up, Got Out of Bed, Dragged a Comb Across my Head

One of the most amusing things about writing a blog is that people you’ve never met form an impression about you from your blabberings, and then, often, when they actually meet you they are astounded that you aren’t “an old grumpy guy” or whatever image they had in their mind. So, in order to confuse you even more, here are some things which I’ve been reading and thinking about and doing while not working on efficient quantum algorithms for the hidden subgroup problem.
