0:00 Part 1#3 "A bit of history"
1:51 Part 2#3 "Putting it all together"
8:48 Part 3#3 "How useful is it..."

This video is about converting a Commodore 1530 datasette (made in Japan) into a boombox. So that you can play your mix tapes wherever you want and play it loud... well sort of (it's only 2x 3W, but that's pretty loud in the living room).

I love how he doesn't hide the mundane parts of the process or make it look more glamorous than it is

What’s the point!?!?!

Cat and Girl wade deeper and deeper into the sea. 'And to bring up children in the ways of a dead world!' continues Girl. 'Hustling them through test prep and extracurriculars - hoping to secure one of the last spots - in a meritocracy that is winking out of existence. Seeing all those sharing your burden only as COMPETITION.' They are now fully submerged but walk on. 'What difference lies between that and a Black Friday fight over a TV at Best Buy? Save twenty years and one tock along the socioeconomic scale.' 'Well you don't get a new TV' complains Cat. They arrive at an underwater suburban home with the lights on and go inside. It may be their house. Cat grabs a remote control and tuns to face the television in the living room. 'But the KIND of TV you have isn't as important as what you can SEE on it!' he says. He clicks. Click click click. The TV turns on. CLICK CLICK CLICK CLICK. The screen shows nothing but light.

I bought a 1080p projector without any smart functions half a decade ago for cheap, and just connect a decade old laptop to stream, or play bluray. Would recommend as a TV replacement (assuming you also have a decent audio-system to hook up to the laptop as well)

I use an old laptop hooked up to an old monitor and old loudspeakers. The only new component is a wireless keyboard with a trackpad. Indeed, can recommend. Kodi is nice if you don't want it to look and work too much like a PC.

Cat and Girl are spending a Sunday afternoon on the island of La Grande Jatte. 'Believe in education begins as a practical step,' says Girl. 'A potential pathway to a higher standard of living. The education itself becomes a virtue - isn't it GOOD to learn? To be curious about the world? Then you look around - at the most successful people in society - and see society's most self-satisfied, least curious members - with thoughts only for their own dominance - so why learn ANYTHING if it doesn't directly benefit me? Am I just a SUCKER?' They now look out across the island's far shore, and then walk into the waves. 'Yet I still believe,' continues Girl, 'even if the beliefs is negative - even if it's a relic - the Edwardian women still wearing a bustle when the rest of the world has moved on.

Uh, is that last panel a reference to how Virginia Woolf ended her life?

Big news! We have a brand new archive page! Now you can SCROLL ENDLESSLY through the archive, or type in a comic number and read from there! I think it's very cool, and much better than the old "giant list of 6000 comics" version.

A very simple energy consideration, but most people will not explain it correctly !

Am I missing something? The block is still moving relative to the ground, isn't it?

In the new inertial system the block was moving to the left before dropping and was sped up to exactly standstill.

Not relative to itself though, which is the chosen frame of reference. My guess is the energy went into the ramp and whatever is connected to it (e.g. Earth). Now off to the comments to see if I'm right.

The second half of the video is a bit misleading, with the break in movement going downhill. But first off, there is no such thing as movement of the block relative to the block. Both systems (camera A, standing still relative to the hill and B moving at speed beta to the right) are inertial, so energy is conserved. In system B, the block is moving to the left at speed -v, and is accelerated to the right in such a way that it comes to a standstill relative to B. Kinetic energy itself isn't Loretnz invariant, but conservation of energy holds in every inerial system.

Unicode 18.0 Beta Review Opens for Feedback

1 Comment

 By: Peter Constable, Chair of the Unicode Technical Committee

The Unicode® Standard provides the character encoding that underlies text in the world’s language on billions of devices, in apps and across the web. The next version of the standard, version 18.0, will be released later this year. A beta review period for Unicode 18.0 has started and is open until July 7, 2026.

The beta is intended primarily for review of character property data and changes to algorithm specifications (Unicode Standard Annexes and certain Unicode Technical Standards that are synchronized with the Unicode Standard). Implementers are encouraged to review these changes for consistency or unexpected issues. Also, a complete draft of the core specification text is available for review during the beta period.

At this phase of a release, the character repertoire is considered stable. No new characters will be added. Characters that are new in this version could still be removed, and their character names or code points could be changed, but such changes would require strong justification.

For this release, 13,047 new characters will be added, bringing the total number of encoded characters in Unicode 18.0 to 172,848. The largest set of additional characters is for the new Small Seal script with 11,328 ideographs. Other notable character additions include:

  • Chisoi script: a modern script used in northeast India.
  • Jurchen script: an historic ideographic script used in northeastern China during the Jin and Ming dynasties.
  • New currency symbols for the Maldivian rufiyaa, Omani rial and UAE dirham currencies.
  • 72 historical mathematical symbols.
  • 73 musical symbols.
  • Nine new emoji characters.

See The Pipeline and the delta code charts pages for details on all of the new characters.

In addition to new characters, there are some significant changes related to character properties or algorithms, including the following:

  • A new Unicode Standard Annex will be added to document properties for large, non-CJK East Asian scripts.
  • Two provisional properties for CJK Unified ideographs will be removed, and two new provisional properties will be added.
  • The derivation of one of the properties used for grapheme cluster segmentation of Indic scripts will be revised.
  • There will be significant revisions to the confusable characters data (confusables.txt) relevant for security.

It was found that wording in the core specification of earlier versions was not completely clear regarding variation sequences and conformance. To provide greater clarity, the text describing variation sequences and related conformance requirements will be revised. See section 3.6.2 in the draft core spec for details.

See the Unicode 18.0 Beta landing page for other noteworthy property and algorithm changes. For full details regarding the Beta review, see Public Review Issue #548. Feedback should be reported under PRI #548 using the Unicode Contact Form by July 7, 2026.

Uh oh, I've seen this movie before https://ionathan.ch/2022/04/09/angzarr.html
