   It seems likely that the esp8266 chip family is being used in industrial automation. It's a very powerful yet cheap chip, making it practically ideal for adding covert spyware. I love it, yet it scares me. It's a little too amaz

   Pointers in Nim can have the "not nil" annotation. The annotation is checked by the compiler.

   It's important to use a language built on strong theory, but the language shouldn't force developers to use exactly the same theory in building their own software. Developers should use the most appropriate theory for their progra

   Yes, there is a part of me that seems solipsistic. There is also another part that sees myself as an automaton along with everyone else. And there is yet another who reasons that at some level of sophistication, it's impossible to dist

   If there is no free will, then the word "choose" is not a special word that implies consciousness. The word "choose" simply means particles flow one direction instead of another due to some combination of other particle

   For me, acting as if people possess free will is a conscious decision. When I'm tired, I sometimes slip into my natural mode of thinking of everyone as automatons. I have to choose to believe that people are conscious. I have to remi

   I agree. Next time I have a disagreement with another coder, I might ask them whether they see computers as primarily circuits, set theory implementations, or AI. (I might add "filing cabinet" as another category.) It would help m

   That's a very interesting categorization. I would generally place myself in the 'electrical engineers' category. I usually code in Python, Javascript, or Java, but I see those languages as essentially C or machine code with p

   This looks very promising: >>> ls `a(a+|b+)a` aaa aba abba Regex filename matching triggered by backticks. I like that design choice!

    I'm sure it could be used that way, but the compile() function and the ast library (part of the stdlib) are a more direct way to create a macro system: https://docs.python.org/3/library/ast.html I've bui

    IMHO the key is your student has programming skills mixed with humility. When I'm hiring, that's all I'm really looking for, and I think that's true for most coding jobs, mainframe or not.

    Wow, as that Wikipedia article explains, the 8008 was effectively developed through a prototyping process involving 100 TTL chips. Also, it sounds like CTC (Computer Terminal Corporation) invented the circuit and later gave Intel full right

    Great points. I'd like to add that IBM's latest mainframe is the z14 (z14 seems to be the name of both the CPU and the mainframe) and it's pretty interesting: https://fuse.wikichip.org/news/941/isscc

    Many thanks for building and releasing this. It's ridiculously easy to install (especially in virtualenvs) and very powerful. When I push '3' or '4', I get informative, stable output. Minor feature request: an expli

    I'd also like to congratulate Utah for recently completing over 100 miles of commuter-friendly bike trails that connect nearly all of the most populous cities. https://www.heraldextra.com/news/local/golden-spo

    A lot of the good road bike trails in the US are built next to slow-moving rivers and canals for that very reason. Rivers tend to carve the land or reroute until the slope is gentle and nearly constant. My favorite way to find road bike tra

    By contrast, I've been running Octoprint (a 3D print server) full time for over 2 years on a RPi with a 64 GB SD card and I've seen no issues with the SD card or RPi. I've been capturing camera snapshots every 15 seconds. I&#

    Yes it's a huge leap, but the leap might not be as big as it seems: if we can figure out artificial gravity, then maybe we can scale up the technology and move stars, leading to more fruitful space travel than metal ships alone can ach

    If c is the issue, then some civilization will use solar systems as space ships. They'll figure out a way to move a star along a chosen path and keep the planets in orbit. The travelers would have all the comforts of home while wanderi

    This is a good article, but I feel like using Postgres instead of SQLite on the server side would achieve his goals even better: - No need to link with C code. There's a pure go driver for Postgres. - You get the 'psql' comma

    What I wonder is how the encryption keys are stored. There are obvious ways to obfuscate keys, but at decryption time, the keys need to be exposed plainly in memory, don't they? So how do game makers like Riot prevent debuggers from di

    That does look like the right info. I think Utah has a typical emission credit program. Maybe xahrepap was overstating the case when (s)he suggested that every Utah land owner has emission credits they can sell. Emission credits seem to b

    Same here. If I start early (particularly due to a meeting), it's difficult to do any serious mental work for the rest of the day because I consistently forget what I'm working on. I can force myself to work anyway, but then I&#x2

    This particular color test is tricky because it's not a simple linear progression. After finishing the test, I converted the RGB values to HSV and found irregular jumps in hue (sometimes 3 degrees, sometimes 6) along with nonlinear cha
