The only gold I see in that gold rush is from acqui-hire.
arek2··on Strongest chess player, ever
Rybka is better than top-20, so I did not claim that.

I was a half-pro ~10 years ago. I won the championship of my country. I wrote an M.Sc. thesis on evaluation tuning. If I'd use the standard approach that I already know, 6 months is a conservative estimate. The question is - what for?

arek2··on Strongest chess player, ever
I have not seen the Stockfish source, but my impression is that computer chess was going round in circles in the last 10 years, and it's still good old alpha-beta search with more refined heuristics.

The biggest value in studying computer chess for a programmer is IMO in seeing all the different performance optimization tricks.

arek2··on Strongest chess player, ever
I don't think that the present situation, when the top chess playing program is free and open-source, is good for innovation.

I estimate that it would take me six months of work to get to the top-20 in the world, and I don't see how I can justify that work to myself.

arek2··on After Google bought Nest, it removed company’s biggest competitors from results
Why did Google ask all those SEO companies to send e-mails to me? Why did Google give them a possibility to blackmail webmasters (disavow tool)? The Internet was not supposed to work this way. I should be able to link to whatever I want, and care only about the users, and not care about how competent or incompetent the search engine creators are, together with the SEO industry.
arek2··on After Google bought Nest, it removed company’s biggest competitors from results
I "nofollow" the links. Also that is additional work and unnecessary burden for webmasters.
arek2··on After Google bought Nest, it removed company’s biggest competitors from results
I have a website 5000best.com/tools with a ranking of web tools, and I received so far about 40-50 link removal requests. I rejected them all. First I answered to those people, later I stopped answering, because that's waste of my time.

The reason of all that nonsense seems to be this article: http://googlewebmastercentral.blogspot.com/2012/07/new-notif... and notifications in Google Webmaster Tools that tell people that spammy links point to their website, but do not tell them specifically which links Google does not like. I understand that Google uses link data mainly to estimate popularity of a website.

I don't understand why so large company, a global monopoly with so large revenue, and so much data gathered, can't figure out which sites are more popular than others without wasting webmasters' time. What's so difficult about that task? Why shift any work burden on website owners?

If this task is too difficult, maybe it's time to support the competition, or create a serious competition. Maybe Google does not deserve to be the largest search engine and get all the profits.

arek2··on 2048, success and me
If someone wants to cure his addiction, here is my variant of the game - 2048 with AI autoplay and taking back moves:

arek2··on How Netflix Reverse Engineered Hollywood
76k micro-genres seems much. For my website http://5000best.com/movies/ I created 40 main genres using IMDb tags together with the 100 million ratings from the Netflix Prize data (I was 43rd in that competition).

Additionally, earlier I extracted and named 12 new genres (those ones on the right) from the Netflix ratings alone - I described the process here: http://arek-paterek.com/book/predict_sample.pdf

arek2··on Show HN: Omegle-style random chat combined with a recommender system
I see that the link was hit by some kind of penalty before a moment, and dropped from the frontpage to the third page. Annoying.
arek2··on Show HN: Omegle-style random chat combined with a recommender system
Thank you for feedback. I wish the users will come back of course.
arek2··on Show HN: Omegle-style random chat combined with a recommender system
Also, people asked about the recommender system. I was 43rd in the Netflix Prize, and you can try out my other recommender systems at: http://5000best.com/movies/Personalized/ or http://5000best.com/movie-galaxy/

I also wrote a 195-page e-book on recommender systems: http://arek-paterek.com/book/

arek2··on Show HN: Omegle-style random chat combined with a recommender system
Someone asked how I implemented the video chat. It's a P2P technology called RTMFP (http://en.wikipedia.org/wiki/Real_Time_Media_Flow_Protocol), built-in into Flash. My server does not transmit the video.

arek2··on What I learned from others' shell scripts
or &>/dev/null
arek2··on What I learned from others' shell scripts
All right, but he wrote: "The 2>&1 > /dev/null puts both output stream and error stream to /dev/null (which means nothing printed on console).". So the intention was different.

PS. I think "which" will never produce anything on stderr

arek2··on What I learned from others' shell scripts
Shouldn't it be:

which curl >/dev/null 2>&1

?

(what I learned from man bash)
