   I find Massdrop's CTRL mechanical keyboard [1] fascinating. AFAIK it is the only keyboard whose keys are not soldered on the PCB, which allows you to swap mechanical key types out or mix-and-match. [1] https://www.massdrop.c

   Crucial questions about the project remain unanswered: Does it suffer from Spectre attacks ?

    If that were true, they wouldn't have faked the picture.

    Interestingly, the hash bucket structure presented in their papers does not match the one on their code [0], but that probably means they've made some sort of improvement post-publications. [0] https://github.com/Micros

    So this was a demo paper, backed by their SIGMOD paper [2]. Interesting work. Their Epoch Protection kind of reminds me of the functionality provided by RCUs [3]. It is unfortunate that they do not provide comparisons with other hash maps i

    The VLDB reviewers of their paper [1] must not have thought much of it because it's accepted as a short paper, which is not a great signal. No comment on the quality of the work though, as I only just started reading it. [1] https:&#x

    Neat little device, looks like a Yubikey clone. One could get a similar device by hacking a Logitech unifying receiver, which contains a ..16MHz 8051 clone in it, and a radio to spare.

    A 22m rod with a 7m notch is perfectly ok. You'd then be encoding 7/22. As others have pointed out, the rod could span the known universe and it would still not matter. Say you found a great message in the representation of 1&#x2F

    If 'x' marks the notch of a rod of length "1", [0---------x------------1], then the implied ratio is not x/(1-x), but x/1 (so the ratio is always < 1.) Even so, your question could be "what is the infor

    you can loosely think of it as writing down a number in unary where each "digit" takes 1.6 x 10^-35 m space to draw.

    Google succeeded because Yahoo used it as its default search engine for years alongside their directory. Google got enormous exposure from that at a point when they needed it. Imagine if your little startup had a "How about you try us

    This is a well written summary. From the article, the European Commission requires Google to respond to these three accusations: > 1. Tying Google’s search and browser apps to the Google Play Store. From the user's perspective, this

    This argument doesn't make any sense. Android was developed via billions of dollars of investment by Google. Google has no obligation to provide a free OSS variant, other than for the parts that are GPL'ed. If all Google is offeri
