There's that, and also visiting a speed test site is an indicator that a particular user is more sensitive to speed than the general user base (and perhaps considering jumping to another ISP). It absolutely makes business sense to pri

Ages ago, I was a professional P2P developer, and I vaguely remember some of the research papers on P2P censorship-resistant reputation systems. Generally, you have public signing keys that sign ratings (say, -1.0 to 1.0) for both content

Yes, A9 was one of the competitors for some of my time at Google, but I'm talking about Amazon basically creating some search engine infrastructure and a framework for building search engines on top of. Selling shovels to the gold min

Google and Bing can already crawl AWS sites just fine. As long as Amazon doesn't provide any first-party search engine, just providing search engine infrastructure, I think it would be a net win for competition. As it stands, if you w

I have a mind to write a PQC daemon to negotiate/rotate WireGuard pre-shared keys. Even though WireGuard uses 3-way ECDH using Curve25519, with a 256-bit pre-shared key, an attacker will either need 2^128 work using Grover's quan

Having worked on Google's indexing system, I can't imagine how much it would cost to write all of the crawling and indexing code from scratch, and then run it on over the visible web. You need to bootstrap somehow form an existin

More than a decade ago, Google had some special-case logic for these "navigational queries". Lee Kai-Fu (head of Google China at the time) said that navigational queries were particularly prevalent in Chinese search traffic. Thou

Back when I started at Google, they at least said they actively targeted "long-tail" queries to gain market share. The thinking was that people would use a search engine until they hit some query that their usual search engine fa

Be careful. Maybe it's a useful rule of thumb, but be careful of the "searching for your keys under the light pole" problem. I worked at Google on rich content indexing for 4 years, more than a decade ago now. Google is pre

If you really want to harm the Putinists, insert an overseas jobs listing link when a Russian IP is detected. Encouraging brain drain is likely the most effective way the tech community can harm the regime. Welcome a Russian, make a frien

Radioactive decay isn't the only source of quantum noise. Johnson-Nyquist kTC noise on a capacitor is another quantum source of noise, for instance.

by KMag 5y ago
No, but Intel's RDSEED and friends rely on quantum electrical noise in conventional circuits to provide true randomness. (Intel uses kTC reset noise from a capacitor or pair of capacitors on the CPU core die, IIRC.)

Oh, interesting. But if the DAG requirement still stands, then it can still be converted into forward-only branches. Why not force that work into the bytecode compiler (or macro assembler) and simplify the kernel logic?

Speaking of alternative representations of eBPF programs, one thing I've noticed about eBPF is that it's particularly well suited to asymmetric number system (ANS)-based compression (such as Facebook's zstd). Asymmetric numb

It's great that Intel is adding a mode where indirect branches must land on specially encoded no-ops. Ideally, they'd also provide special encodings for "push rbp" and "sub rsp, x" (for the -fomit-frame-pointe

The historical longevity of hard-wired pointer tagged systems isn't great. Others have alluded to early m68k Macintoshes ignoring the top 8 bits of pointers, resulting in later Macintosh systems needing per-application compatibility mo

I certainly agree with your broader point: nobody is handed a degree from MIT. If they have a degree, they've put in the work and have a good grasp of the subject matter. (Also, MIT doesn't give out honorary degrees.)

Roughly nobody at MIT brags about SAT scores (at least when I was there 20 years ago). Any test is most sensitive around a given range. I think most MIT students are performing well enough in math that most of their mistakes in the SAT I
