Hey there, I was enrolled in the 2013 edition of Analytic Combinatorics, but it seems that I am out of luck - no access to the materials either way. :-/ Does anyone happen to have the name of the 2013 edition? Or is it by design that t

So I do not know (in the mathematical sense) that ChipKill won't create a problem, but I think it is unlikely. In general, if the ECC infrastructure works (e.g. DRAM detecting bit corruption and reporting it to the OS), the odds of a

Hey there, if anyone wants some more background on all the negative side-effects of the current regulation, I wrote a lengthy blog post on the problems with the current phrasing of the Wassenaar amendments here: http://addxorrol.

This is a good point really -- the BND seems to be exceptionally gaffe-prone. It seems the current BND president has to leave the office every few years over some affair or the other...

What I suspect is actually not "helping", but rather "blind trust" -- e.g. just having an arrangement with the US where the US sends in "selectors" and the Germans send over the data; and nobody competent/

Do you have similar numbers that are adjusted for "amount of money in the acquisition / IPO" ? (genuinely curious)

Yep, that was me :-) - although already post-acquisition. Alan Mycroft had invited me over, I really enjoyed the visit :)

This touches on an interesting conundrum: I was one of the founders of zynamics (exit to Google in 2011), and I have been looking for attractive angel investment opportunities in Europe for a while - and also have tried to volunteer some ti

Katsuyama created a trading platform that nullifies one HFT strategy, namely latency arbitrage. Stieglitz is much more critical of the strong efficient market hypothesis in general; from this, he derives a number of positions that are ana

As someone who has been very closely involved with Infosec and who has followed all the vulnerability market rumors, I have never heard of "pays the companies to not fix them" before, and I strongly doubt the veracity of that st

What you are describing as a background is all part of a "normal" math/CS undergrad education (at least in Germany where I studied). From a level of the mathematical difficulty, Elements etc. (but also current-level research

Agreed; I guess my complaint could be best phrased as "the paper does not sufficiently address the complexities of determining whether you are in such a cycle, and the fact that many people that struggle actively search for more concre

Bosses do, but the article does not necessarily provide any real solutions. The only clear thing to take away is "be aware that you may be causing a vicious cycle, and try to look out for that/get out of it" - which is a leve

We had lots of hilarious answers to the question of what we do, but none are fit to post :-). As soon as you mention "reverse engineering", you end up in long discussions about EULAs; so you're immensely popular at cocktail p

Perhaps as a "cheer up" story: We applied to YC in their very first batch and got rejected. It is unclear what the reasons were -- but there were many reasons why it was understandable for YC to reject us. Among other things, the
