Cool, and I love the retro font. I had a Vic-20 (early 80s) and Commodore PET 2001 (1977) I am learning Odin, and I was going to try creating live coding environment with scripting in Forth and with the gui and rest in Odin, but for audio and graphics. I was inspired long ago by Paul Batchelor's Sporth and Tidal (now tidal cycles?). Forth is a great language. You can make an compiler/interpreter in a few days. John Earnest's ok.js is also cool. I like stack and array languages, so when I am not playing in J, I use Uiua. Uiua has the capability to do audio and graphics/animations and scratches my array/stack itch.
I picked up a book around 1977 on the PDP-11 processor and worked my way through it with pencil and paper to understand the architecture when I was around 13. I saves up my summer job money and bought a used Commodore PET 2001 for ~$700 with cassette drive and 8kb and a green phosphor screen. I later bought an expansion for it that gave me 32kb. The PET's 6502 was simpler, but that DEC handbook and working out registers on paper gave me a strong foundation in computers. I realized computers would only be tools and always managed to take jobs outside of comp. sci. or IT, but always used a computer and programmed utilities for every job I had in any language I fancied at the time and throughout the years: C, Basic, asm (6502, PIC, Scenix, 68000, 8086/88, now ARM/x64), Forth, Lisp (Lush/Lush2 lush-users on Sourceforge with Yann LeCun to get Lush running, APL, J, Logo, Pascal, Factor, Java, Python, F#, now Rust, Odin, and J is still open on my desktop daily). I had in mind how people were talking about high-paying jobs if you learned WordPerfect, and it was "the future" back in 1991-93. I felt people were putting the tool before thought, intelligence, and process. I did dip into DBA and IT here and there for a little bit, but I thoroughly enjoyed writing embedded software for the window animation I was working on for a display company, and interactive prox switches on the store window at Sachs to trigger a pneumatically actuated Nutcracker to raise his arm and close his jaw and other fun kinetic pieces in the late 90s (Pre-Arduino saturation days - Parallax Basic Stamp, Scenix, PIC, and PCBs from scratch by hand with resist and etch). Kids loved pressing the Nutcracker switches! The reason I learned so much was that you had to go to the library, write a letter or eventually by the 90s email and user groups, and just plain figure it out through trial and error on your own. I had a VIC-20, Commodore 128, Amiga 500/1000, then a PowerPC Mac running Mach Linux in the late 90s/early 2000. I loved Commodore. It's a shame. They were the best option for the buck.
A great tech book on symbolic computers in general and Lisp machines, is Peter Kogge's 1991, "The Architecture of Symbolic Computers". I believe new efforts by people like Yann LeCun will counter the "LLMs or bust" monoculture along with SOC/ASICs, in-memory compute, neuromorphic chips, dataflow, optical/analog hybrids , etc. that will bring a healthy correction or alternatives to the Von Neumann architecture.
For me, vigorous exercise, riding my bike, running, jumping rope, has always made me feel better mentally and physically whether it was a pathogen funk or just life and feeling down or symptomatic as some describe below. I always check my kids and myself after hikes, especially in tall grass or shrubs. I've found ticks here and there over the years. The cathartic effect of high-intensity exercise where you push yourself to what you think is your limit is amazing for your physical and mental well being. The old Sufi saying, "Movement is life; stillness is death" is my mantra. I have friends who avoid hiking for fear of ticks and Lyme disease. It's a shame, since being outdoors in the sun, smelling the woods, and taking in the views while walking are priceless. Movement over pharmaceuticals.
Yes, and AdaCore's tooling is formally verified and produces reports already familiar to aerospace, railway, and auto auditors for verifying certifications making it attractive to this industry segment of high-integrity apps. Memory safety is taken care of mainly through the features Ada/SPARK2014 offer in creating safe, high-integrity programs, correct.
We passed on Rust for Ada/SPARK2014 to write to bare metal on Cortex-M processor for real-time, high-integrity, and verifiable mission-critical software. Rust is making strides to be a future competitor, but it's new to the formal verification tooling and lacks any real world legacy in our domain. Ada's latest spec. is 2022. Other than AdaCore's verified Rust compiler, Rust still does not have a stable language specification like C/C++, Lisp, or Ada, SPARK 2014. I have no doubt that it will start rising to tick all the boxes that Ada/SPARK do right now with their decades of legacy in high-intetrity, mission-critical applications. The mandate to use memory-safe software put into effect this past Jan 1 2026 puts some wind in Rust's sails, but it's more than memory-safety in this domain. Plus, I do not enjoy Rust, but Cargo is nice. We're looking at Lean for further assistance in verifying our work. I think there was and is lot of Rust evangelism that will also carry it forward and boost even more Rust popularity,
Everytime I start jumping rope after a long break like Winter. It immediately starts trending lower a few points in 3 to 4 days, and plateaus after 6 weeks or so. I've averages as low as 54 bpm, but not as consistent as 58 to 60 bpm over a six month period. Granted, I tend to sleep better, have lower stress anecdotally and quantifiably by my Garmin watch's data. It has to be said that I usually add more exercise, because the rope jumping greases the skids so to speak. Good begets good.
From my comment below, we used Betamax back in 1982 for film class and would go back to editing it on a tape-to-tape deck, so starting with Betamax vs. VHS meant you had less degradation in the final edited product, since you started with higher quality. Sort of like editing RAW vs. JPEG photos nowadays to start with more resolution/information. For me streaming vs. my Blu-ray stuff was about cost. A $39 Blu-ray disc vs. a $12 movie or free movie with subscription. Amazon Music took away a purchase I had from 2014. I could no longer download it, since something changed with their licensing agreement. I have digitized my DVD/Blu-ray discs, since the discs don't last forever. I keep a streaming rez and a hi-rez copy of my faves.
Yes, but you're forgetting editing wasn't digital/digitized. You would copy from one tape to another, so a degradation issue. It's not the TV's capabilities, but if you started with higher quality you would get less overall degradation. I took film classes in TSOA at NYT back in 1982, and one class was film production and the other was lugging around a huge deck and camera in Betamax and then going back to a tape-to-tape transfer editing deck.
I'm going to download and check out Mine and Coalton. Right now, I use Neovide and Lem interchangeably. However, I am in deep with Shen. I bought a hardcopy of The Book of Shen, 5th Edition, and I still have Peter Kogge's 1991 text, "The Architecture of Symbolic Computers". I suspect the Hindley-Milner type system in Coalton will be more familiar to the Haskellers out there, but it is not as strong as Shen's Sequent calculus type system. In Shen, computation is allowed in side-conditions (if, let, and, etc.), so you can compute over terms inside types. Shen wins for raw expressive power and programmable types. Shen is very portable, but being a DSL, Coalton must integrate nicely with Common Lisp. And you get native exe's. Glad to see a simple way for people to program in CL or Coalton without having to go through the decades I have done with Vim and Emacs. VS Code bores me, but it is practical, even if it seems like junkyard truck with everything bolted on or hanging off of it.
I ran Minix around 1991 on my Amiga computer. Minix had a smaller attack surface and isolation provided by its microkernel vs. Linux's monolithic kernel. I had the Minix textbook, and it was easier to think about it because of the split along modules. I personally think Minix vs. Linux was very similar to Betamax vs. VHS. Betamax was technically superior, but the market picked VHS. I may run Minix again on my old Lenovo T430u from 2012. I was amazed that some of the code to Minix was in the appendix of the book, sort of like the magazines with pages of code to hand type in games or toy programs. I guess I liked MS-DOS for the same reason: tinkering, from my PEEK and POKE back in my Commodore PET 2001 (1977) and Vic-20 days...
Wow, 160 kWh/month! My family of four uses as much as 790 kWh/month in the high-heat or very cold season, with an annual average of 650 to 700 kWh/month. We pay around 0.13 USD/kWh, however, when you add the taxes and supply charges, it actually averages out to 0.28 USD/kWh...Granted I have two younger children at home, and my wife cooks fresh meals all the time - fresh-baked breads, etc., so we don't eat out much at all. We have an electric oven, electric washing machine and dryer, and electric cooling and heating (split unit HVAC).
A delta of 3 bpm on sauna days corresponds to around 4% delta if the baseline is 72 bpm. I've gone from a resting heart rate over a 7-day average of 64 bpm to 58 bpm by jumping 15 min. of rope a day, 4 times a week. I've lost weight, body fat, and I feel like my body is more efficient with corresponding lower heart rates throughout my active day. I like saunas for recovery and aches, they put me in a relaxed state after, and I believe the dilation is flushing my system. Like anything else, moderation. Perhaps I will add sauna to my weekly routine 1x per week or less.
Since it's not a battery storage setup, the energy being sent into your home circuit alleviates demand by a small amount. Where did they come up with 10 to 25% savings? Factors such as an optimal view of the sun for as much as possible, south-facing or biased East or West, would be the max. payoff. Night would be a zero net gain. At a savings of $7 a month, the panel would pay for itself in maybe 10 years not factoring in government subsidies. You need to keep it clean as well for it to maintain its potential output.
Correct, not millions of Demodex mites, which are usually in the hundreds to thousands on a typical, non-infested human. The millions should be the general amount of mites and other symbiotic/parasitic on and in your body. Thanks!
Yes, and I think it's important to highlight that Iverson would write APL on chalkboards and paper when working on math at times. I am sure some people here can hand write a program, but it seems so much more akin to writing math. I am in J daily, APL once in a while, Uiua more frequently, but J is the only one I actually write in my journal and then try it on my J phone app or when I open up my laptop. The intro books for J are great for working through math and learning J - Concrete Math for Computing in J; Easy J; Calculus; Arithmetic - https://code.jsoftware.com/wiki/Books
