mrspuratic··on Ask HN: Which TV do you recommend for privacy?
VESA mounted with a generic VESA plate "doubler" solved the aesthetics for me. Out of sight and all. Though I now need to replace its fan with the new one sitting in a drawer.
mrspuratic··on Europe's fires are just the start
Portugal has about 10% forested land, of which an estimated 25% is non-native eucalyptus (an active pyrophyte), and over 50% in some areas. I've seen the aftermath of eucalyptus forest fires while travelling through Alentejo.
mrspuratic··on The Beam Engine
My uni had an original 1800s style beam engine (from a whiskey distillery) as a feature in the Engineering faculty building foyer. It did move, but driven by electricity, and only a couple of times a year AFAIR.

mrspuratic··on 10 REM"_(C2SLFF4
My technophile uncle gave me one in the late 80s when he upgraded, even came with a monster of a daisy wheel printer. Can't remember what the WP was, but I remember being amused with V1.0 Microsoft Basic which came on a cartridge.
mrspuratic··on TIL: You can make HTTP requests without curl using Bash /dev/TCP
This feature has been part of bash since 5.1 (ca 2020), though it may not be enabled in all distros.

  cd src/bash-5.3/examples/loadables
  make accept
  enable -f ./accept accept
  (accept -r RHOST -v SOCKETFD -b 127.0.0.1 8000; 
    read -u $SOCKETFD SOCKETDATA; 
    printf "%s: %s\n" "$RHOST" "$SOCKETDATA";
    printf "goodbye, world\n" 1>&${SOCKETFD} ) &
  nc 127.0.0.1 8000 <<< "hello, world"
For real use you may need to add "exec {SOCKETFD}<&-" to close the FD.

mrspuratic··on Shunning AI is the human choice
Not as long as there's money to be made schilling and selling "qualifications" in prompt engineering.
mrspuratic··on Poland is now among the 20 largest economies
This is how it works. Ireland was a net beneficiary until 2018, and now it is a net contributor (one of only 10 net contributors). These are decades long investments, Poland joined in 2004. Per capita Poland is not the "greatest" beneficiary but I don't think that will help win any arguments for those already resistant to facts or reasoning. https://www.euronews.com/business/2024/12/09/eu-budget-who-p...

mrspuratic··on Quarkdown – Markdown with Superpowers
"updoc" is still my favourite joke name. A long time ago (predating E lang's updoc afaict) I wrote a toy markup for semi-technical docs, named so with the specific intention of dropping it casually into conversation. Still funny :D

mrspuratic··on Ireland shuts last coal plant, becomes 15th coal-free country in Europe (2025)
Smoke yes, but you're also turning a carbon sink into a carbon source. At ~16% of the island's surface area, peatland stores an estimated 53% of soil based carbon. (source: Irish Peatland Conservation Council)

Hydro can help a lot with that. Grid stability is a big issue with non-synchronous power sources (SNSP).

mrspuratic··on Why some clothes shrink in the wash and how to unshrink them
I got a Foxydry (Italy) wall-mounted rack a few years back, best €100 I spent that year. Bottom rack folds up flush to the wall, top rack raises nearly to the ceiling. Towels dry fine spread over extra bar or three to allow for better air circulation.
mrspuratic··on What a year of solar and batteries saved us in 2025
No fridge? That's a heat pump.
mrspuratic··on Efficient method to capture carbon dioxide from the atmosphere
This. I have that type (regenerative MHVR) installed in the attic for upstairs, and a synced pair of in-wall ceramic (recuperative) types on opposite sides of main living area downstairs (eliminating ducting, albeit with reduced efficiency). I haven't attempted any energy/ROI calculations but fresh filtered air, lower humidity and good nights sleep are well worth the claimed single-digit watt power usage to me.
mrspuratic··on Aliasing
In old school FORTRAN (I only recall WATFOR/F77, my uni's computers were quite ancient) subroutine (aka "subprogram") parameters are call-by-reference. If you passed a literal constant it would be treated as a variable in order to be aliased/passed by reference. Due to "constant pooling", modifications to a variable that aliased a constant could then propagate throughout the rest of the program where that constant[sic] was used.

mrspuratic··on CO2 batteries that store grid energy take off globally
Ireland is lucky enough to have several suitable sites, but just one operational: Turlough Hill, which has been running for over 50 years and is in use daily. It's at least as useful in terms of grid stability and (relatively) rapid dispatch as capacity. Output ~0.7% of total daily (~120GWh), ~5% of daily peak (~6GW), wintertime figures. For comparison electricity usage has increased about 8-fold since it was deployed in 1974.

mrspuratic··on Microsoft is quietly walking back its diversity efforts
Total US Fed. Gov. contracts for 2024 was (according to gao.gov) $755B. That's a lot of drinking, never mind any anticipated AI spending boost next year.
mrspuratic··on Unpowered SSDs slowly lose data
Not problematic, minor pedantry. With much time spent reading (and occasionally writing) technical documentation it's octets, binary prefixes, and other wanton pedantry where likely to be understood/appreciated or precision is required.

FTR, ECMA-130 (the CD "yellow book" equivalent standard) is littered with the term "8-bit bytes", so it was certainly a thing then. Precision when simultaneously discussing eight-to-fourteen modulation, and the 17 encoding "bits" that hit the media for each octet as noted in a sibling comment.

Now, woktets on the other hand...

mrspuratic··on Unpowered SSDs slowly lose data
CD storage has an interesting take, the available sector size varies by use, i.e. audio or MPEG1 video (VideoCD) at 2352 data octets per sector (with two media level ECCs), actual data at 2048 octets per sector where the extra EDC/ECC can be exposed by reading "raw". I learned this the hard way with VideoPack's malformed VCD images, I wrote a tool to post-process the images to recreate the correct EDC/ECC per sector. Fun fact, ISO9660 stores file metadata simultaneously in big-endian and little form (AFAIR VP used to fluff that up too).
mrspuratic··on Large integer precision error in Bash command output rendering
It seems like it, but it can't be only that. A float64 representation of an int in the range 2^58 to 2^59 should be rounded to multiples of 2^6, i.e. 348555896224571968 as you found (3.48555896224571968E17) (the final digit 9 in the math.log2() expression was lost, it's 2^58 not 2^54) The unexpected output (according to the bugreport) arises from javascript, it does NOT round like everything else for reasons I don't understand. It seems to prefer rounding to arbitrary multiples of 10 in my limited testing.
mrspuratic··on Drilling down on Uncle Sam's proposed TP-Link ban
The whole Tapo/Kasa interop thing was badly handled too a few years back. Put me right off, when most were dangling the seamless integration carrot to distract you from the vendor lock-in.
