I think setuid executables would be a good place for rust or go, but I have reservations about the kernel itself.

Non CS people may not understand this at first, but you are exactly right. A 'tree' is connected and has n-1 edges. So there can only be precisely one path between any pair of vertices. He may have meant a general connected graph

I was under the impression that the Romans were more applied/practical and less theoretical, but I may be wrong. I got that notion from a professor I had years ago who was fond of saying, "The Romans built roads. The Greeks talked

I love the solar g-shock wave ceptors. They blend radio signals (to sync the time), toughness and solar power. They are almost as accurate as GPS time on smart phones, yet much simpler.

Agreed. I get cheap Stanley tools at Walmart that have a no questions asked lifetime replacement. Walmart is still cheap, but becoming more like Sears once was in quality (on some items). As for Amazon, I like them too. I know they have a l

Non-ionising radiation can cause harm. Ask welders (burnt eyes). Get a cheap auto-darkening welding helmet, put it on and point a TV remote at it. The levels of IR in the remote are small, but the sensors still activate in the helmet.

I think James Mickens (Harvard CS) has it right. ML is inscrutable, black-magic that no one really understands. This is long, but worth watching: https://www.youtube.com/watch?v=ajGX7odA87k

I see this every time I try to log in to twitter. I've used different computers, different browsers, different operating systems (Debian, Xubuntu and Windows 10). I've opened tickets with twitter (they don't seem to care). I&

Hire "problem solvers" who have CS degrees and pay them to solve your problems. They should have a practical bent and should accept 80% solutions (good enough). That is key to getting stuff done. Avoid non-pragmatic roles (archite

This has been my experience as well. It's either retirees or stay at home moms/dads that drive the buses part time. They may not be purely volunteer (no pay), but it's definitely a part time job. Couple of hours in the mornin

Slightly wrong. Here's the original: "There are only two kinds of languages: the ones people complain about and the ones nobody uses." Bjarne Stroustrup's FAQ: Did you really say that?. Retrieved on 2007-11-15.

Which one? Python 3.5.x or 3.7.x or something else? Version 3 should be version 3. Anything written in 3 ought to work on every Python 3. Not so in the Python world. And that makes it a mess to use (unless you Dockerize every script). Perl

Ping is how I found a compromised server once in a large, poorly wired server rack. The sys admins were out and the supervisor did not know anything about the server room (nor did I... the security guy) so he pinged the infected box from a

I wrote a lot of software before I ever took a CS class in college. The only things you'll get from a CS degree are the ability to prove problems are NP-Complete, learn how to do Dynamic Programming, reductions from one problem to anot

I obtain the SHA1 hashes published by HIBP, load them into a bloom filter and use that for checks. It's super fast (constant time lookups) and avoids a network dependency/third party service. Here's working Go code: https:&#

It's actually rather expensive storage compared to other cloud providers.

I'd just use IPv6 and Go from AWS. No need to have 1000's of machines.

Stop parroting these criticisms of OpenPGP without offering concrete, working replacements that are widely adopted and have open standards. Some kid recently tried to have OpenPGP support deprecated from Golang's crypto-x package. And

I agree 100%. A Go fat binary has all the advantages of Docker with none of the added abstractions and complexities.

End to end encryption was once classified as a munition. If the data is not end to end encrypted, then it is public. Everyone should understand this.

I had a friend who was in the Marines and he told me once that they wore panty hose when training in areas with ticks. He said the only downside was that they can be hot in the summer time.

When you do buy an individual copy, it comes with your name printed in the footer of every page. I had a copy of one once (won't say which one) and I could not let my boss read it. For many topics, national standards (like NIST) are gr

I was a dumb phone user for years. I carried a refurbished LG 105c for about the last six years. The battery was great. I could go an entire week without charging it. MMS messages started crashing the LG in the past few years and this incre

Very nice. I've never used a Golomb Set (looks interesting). I bet we'll see more organizations doing this and maybe in five to ten years, it'll be the norm.

I hope that the SHA1 hashes remain freely available for download. I use them to build a bloom filter for password vetting. We should all do away with password complexity rules (except minimum length) and simply test a large, comprehensive e
