A Fictional Compression Metric Moves Into the Real World

tommeke100 F1 score, precision and recall (133 comments)

Sounds a bit like the f1 measure used in classification systems, where the F-score is the harmonic mean of precision and recall. (where trying to higher precision yields lower recall and vice-versa)
however, I'm wondering how stable this Weissman score is. Compression algorithms might not all perform O(n) where n is size of data to compress.
Or it may actually give a very high score to something that doesn't compress at all.
public byte[] compress( byte[] input) { return input;}
I bet this gets a high Weissman score ;-)

Amputee Is German Long Jump Champion

tommeke100 Re:No, no unfair advantage at all... (175 comments)

I can't speak for long jump, but in high jump your shoes are definately regulated.
you're not allowed for example to have shoes that have a sole thicker than a certain amount.
I just looked it up and apparently it's the same for long jump shoes.
So yes, I don't think springs or a blade qualify as valid shoes in this case (especially if the blade is 18 inches longer than your other leg!).

In France, Most Comments on Gaza Conflict Yanked From Mainstream News Sites

tommeke100 Re:Or maybe you're not so good at math (501 comments)

Selective, maybe. However the chart is a bit outdated, as there are over 800 casualties already, and that was 2 days ago.
So, in that given chart, the Palestina conflict just climbed 6 places.

Math, Programming, and Language Learning

tommeke100 Why Math matters (241 comments)

No you don't need math to write an iPhone App or an interactive website.
You do need math to understand why looking up some keys in a HashMap is much faster than iterating over a vector.
You do need math to understand why some encryption algorithms are better than others
It just gives you the tools to better comprehend what's going on under the hood, so you have more information to make the right choices in how to implement something.

Elite Group of Researchers Rule Scientific Publishing

tommeke100 flawed methodology (123 comments)

They took a publications database between 1996 and 2011, which contains about 15,000,000 authors.
There they found only 150,000 published every of those years.
Of course not all of those 15 million have been working in research for 16 years. Most graduate/PhD students are in research for 5 years and then they need to find another job.
Actually most people at my company were author or co-author of a paper at some point, and we only published because of some grants that required it.
So if you take out the people who really only have a couple of publications, or published for a small period of time, the picture will be completely different.
Take into account that you need people who's career actually span the 1996-2011 period (which filters out probably like 30% of people genuinely having a successfull academic career), and they actually paint a realistic picture of who the profs are or research leads.

Python Bumps Off Java As Top Learning Language

tommeke100 Re:"Top Learning Language" ...OR... (415 comments)

You can implement a programming language in python.
We used Scheme (simple LISP derivate) at our university in the nineties (good old Abelson and Sussman).
Didn't even have classes (objects) back then!
Still it was perfectly possible to simulate objects (state and behaviour) by lambda expressions.

Same can be done with Python, I'm sure.
Writing a meta-circular interpreter in any language will teach you about memory allocation.
Maybe not pointer specific notation as in C.

Washington Redskins Stripped of Trademarks

Apparently the PTO did not mind trademarking the symbol for Pi, so maybe they should call themselves the Washington Pi's from now on.

Interviews: Ask "The King of Kong" Billy Mitchell About Classic Video Games

tommeke100 Re:A Lost Era (122 comments)

Same question.
I grew up playing Wonder Boy, Double Dragon, Yie Ar Kungfu, etc...
Grew out of it after Street Fighter 2.
Most of these games could be played and beaten with a single coin (Double Dragon being my favorite).
Then something changed. Suddenly you couldn't even finish the first level without putting back money into the machine.

Did you also feel this transition (or maybe those games aren't classic enough), or did I just suck too much and these games were beatable after all?

Chelsea Clinton At NCWIT: More PE, Less Zuckerberg

tommeke100 Re:Wait... (255 comments)

There was a girl in our first year of CS who was a very hard worker, but just couldn't handle the advanced math.
She switched to med school after she flunked and passed with flying colors.

It really depends on what you take as basis for a 'tough' curriculum.
Med school and veterinary school may require you to work 'harder'. But with CS and Math, if you don't get it, you just don't get it. No matter how hard you work.
I wouldn't be able to do Med school though, I faint at the sight of a needle ;-)

I had the following courses in my first year of CS: differential and integral calculus, Linear Algebra and geometry, Higher Algebra, Algorithms and Data Structures, Logic and Formal Methods, Interpretation and Structure of Computer Programs, Information Systems.
Web Development class....Nope...doesn't ring a bell.

RightsCorp To Bring Its Controversial Copyright Protection Tactics To Europe

tommeke100 Re:RightsCorp (196 comments)

The article says that RightsCorp sends settlements for 20$ a title.
So, it's not like they will sue you for thousands if you happen to download the latest GoT episode.
Although I don't concur with their process (sneak their way into getting personal info by avoiding courts), at least they are asking for a 'reasonable settlement'.

Microsoft Cheaper To Use Than Open Source Software, UK CIO Says

You think they are arrogant because their discussions are public. It's all happening on public boards and mailing lists.
Microsoft's internal kitchen is private, so you won't hear their developers speaking out publicly as often.
