symmetricsaurus··on Liquidfun – 2D physics engine for games
I assumed it was a js lib when I saw it. Made me kind of confused when there were no live examples, only videos.
symmetricsaurus··on An open-source fully homomorphic encryption library
The README has lots of really cool words and names and things. But it doesn't say what homomorphic encryption is or what it is good for. Could someone enlighten me?
symmetricsaurus··on Emacs setup for Python development
That looks awesome. Having used the WMII window manager it looks quite familiar. Even then the learning curve seems steep.
symmetricsaurus··on Rails' Insecure Defaults
I don't agree on WEBricks verbose headers being a problem. It should not be used in production anyway and during development getting lots information easily is obviously very useful.
symmetricsaurus··on Shapecatcher: Draw the Unicode character you want
Tried to draw an alpha but it didn't get it.

So far I haven't tried Shapecatcher a lot but I think that http://detexify.kirelabs.org/classify.html works much better. Detexify is of course only for LaTeX symbols and doesn't do unicode.

To be useful Shapecatcher needs to become better at recognition.

symmetricsaurus··on That Daily Shower Can Be a Killer
Angband(the roguelike) is an excellent teacher of the point made in the article.

The game is quite long and if you die you have to start over from the beginning. You can also be killed in one turn if you are unlucky and not careful. The only way to win is to lower the risk to die at each turn sufficiently that you can play through the 100 000 turns or so that it takes to win.

Playing it has really given me perspective on risks in a similar way to the author of the article. In real life you end up doing some things a lot of times and then the risk has to be damn low.

symmetricsaurus··on In 2050, Flight Time From Europe to Australia Will Be 90 Minutes
What is new here? Rocket powered aircraft concepts have been around at least since World War II. This seems to build on proven technology so why should we need to wait until 2050?
symmetricsaurus··on How Japanese Kids Learn To Multiply
The videos only show the technique using small digits. For the larger digits this method quickly becomes cumbersome.

Latttice multiplication is much better for large numbers and deals with a lot of the carrying of overflowing digits which occurs in both normal and "Japanese" multiplication.

edit: spelling

symmetricsaurus··on Why tiny Stockholm has the most stunning startup ecosystem since Tel Aviv
1.4 million in the urban area and 2.1 million in the metropolitan area is not exactly tiny.

Tel Aviv is for example smaller, but I guess that the comparison is to the bay area/silicon valley or something like that.

symmetricsaurus··on Nokia 'Here Map' arrives at the App Store
It's quite quick on my iphone 4 but the actual maps are blurred. It would seem that they are rendered at the "old" iphone resolution. This gives the app a very unpolished look unfortunately.
symmetricsaurus··on What you should know about IPv6
That was interesting and highlights that I do not know a whole lot about networking. What would be a good source to get a basic understanding of these things work?
symmetricsaurus··on A little hexapod robot that I made
Nice little robot. The video is a little short, is there any more footage?
symmetricsaurus··on Blaze: Next Generation NumPy
I don't get it. Am I supposed too just look at the slides from a presentation and get what it's about? If the presentation is any good that will be quite hard.
symmetricsaurus··on Don’t mess with IBM
I agree that some more references are in order. As it is now, all this post does is spread rumors. At least the lawsuit happened but it's hard to tell about the rest from the information we're given.
symmetricsaurus··on Such a Little Thing: The Semicolon in Rust
Indeed. On a Swedish keyboard the semicolon is not the biggest problem though. {}[] are since you need to press right-alt+number keys to get them. Really awful. It takes a very short time using an American keyboard for coding to realize its benefits.

Still, even on an American keyboard () are not terribly well placed.

I've been thinking about adopting the NEO2 layout(with some modification so that I get all of åäö) but haven't gotten around to it yet. Has anyone tried that for programming?

symmetricsaurus··on The Ultimate Vim Distribution
I think it is good for showing some different plugins and configuration options available in Vim. I think I will use the the included .vimrc file and plugins to look at to get ideas for my own .vimrc. The default in the distribution makes my Vim look like a christmas tree, which I don't really like.
