There are quite a few people who murder despite the risk of incarceration.

I hate to think how many people would kill if it were not illegal. Think about that. Then tell me its not a deterrent.

Ask LG who has agreed to their wiretapping. They can't tell you if some guest in front of a TV has agreed or not.

How can that be concent?

Re:216M Spy TVs – The LG Smart TV Problem [video] on Monday September 07, 2026 @11:06PM (#49605288)
IANAL but without concent I think LG is comitting a crime here. The owner who ostensibly agreed to obtain concent through the ToS might be breaking their agreement, but wouldn't that be a separate issue?

ToS and other click licenses have been making shit up for way too long.

China destroyed a sat with a laser years ago. Not disabled - destroyed. It created a bunch of debris.

If GPS goes down, most of our communications will go down. A lot of other stuff falls from there. I suspect we'd be OK after a brief adjustment, but it would be very disruptive.

Can it please finish itself before it eats the table, chairs, and dishes?

>> Similar formulas exist for moments, to compute the inertia matrix for a rigid body.

Fun fact. The inertia for any rigid body can be represented by 4 point masses forming a tetrahedron. If you diagonalize the inertia matrix, the coordinates of the 4 point masses can be (x, y, -z) (-x,-y,-z) (x, -y, z) (-x, y, z) where x,y,z are easy to calculate (I wrote this all down ages ago). You can also represent any point on the rigid body by its barycentric coordinates relative to those points. I believe an impulse can be applied, by finding the barycentric coordinates of the point its applied and using those coordinates to distribute the impulse to the 4 masses.

This is all really cool with one huge exception. The 4 points become coplanar for large flat objects, which means the z-height is really small for a piece of sheet metal for example.

Better still, you calculate the signed volume of the the tetrahedron formed by the triangle and the origin (4th vertex).

@yassa How long did this take?
>> The yuan will never become a reserve currency as long as China maintain tight currency controls around importing and exporting it. It's very difficult to (legally) send CNY out or China.

Did you read the article? It seems that may be changing.

I dont think its exponential innovation. Rapid incremental innovation is happening very fast with some occasional bigger bumps.

The separation is not total but its more than used to exist.
Right? "The government" as a whole can't have it both ways. Eliminate older navigation systems because GPS is everywhere, AND run around jamming GPS.
An entire generation of programmers was created in the 1980s from typing code from magazines. OTOH the only way to run it was to first type it in. Today people have too many options to be bothered I suppose.
Does FreeCAD use triangle meshes? CAD is usually NURBS surfaces, which require similar algorithms but on curved surfaces.
>> This is the second ChatGPT shared conversation I've seen today that is truly fascinating.

We recently had some bugs fixed in the geometry kernel of solvespace. Not much conversation, but the analysis from the AI was amazing:

https://github.com/solvespace/solvespace/pull/1729

https://github.com/solvespace/solvespace/pull/1730

https://github.com/solvespace/solvespace/pull/1731

From the Validation section of PR 1730:

"The model family was reconstructed programmatically (parameterized cuboid stack) and swept over 2,304 configurations — extrusion directions, workplane-normal orientations, sketch windings, D's plane/height/depth/extent, including all the exact-coincidence heights. Zero failures with the fix; 576 failing configurations without it. The generator is available on request."

It looks like it wrote a python script to generate test cases in our file format for testing. Just... you know, as a side quest.

I recall reading that the corals can reproduce both sexually and by cloning, with most in nature using cloning. The researchers brought them back to a lab and bred a bunch of them and found a lot of offspring could thrive in the warmer more acidic water, so they wanted to reintroduce them to a reef (or maybe they had). Been a while but it was interesting. Not sure what it takes to shift away from cloning in nature, but waiting for most the reef to die off seems backwards ;-)

>> Going forward, however, I expect the inference market to grow much faster than training costs (and that includes the assumption that training costs will continue to skyrocket), which means they really can make it up in volume.

But as inference becomes cheaper, some of the market will move to self hosted inference. I look forward to someone supplying small servers designed to run inference locally.

With or even without open models these companies are selling compute, and we've been making that rent vs buy decision for 60 years.

Re:ECC and DDR5 on Monday July 20, 2026 @10:07AM (#48979084)
>> Everyone repeats the statement DDR5 on-die ECC isn’t a replacement for regular ECC, but nobody ever shows data on DDR5 bitflips.

That's because the on-die ECC cannot detect errors in the transmission of data from the DIMMs to the CPU. It seems like on-die ECC is meant to "hide" some level of errors to make less reliable RAM chips appear good. I have no idea if that's a reasonable way to do it, but it seems like it could be misused. Like TFA suggests, we need to know how the two levels of ECC interact.

>> The commits are in my fork if anyone wants them but I can’t imagine why anyone would.

This recently happened with solvespace (I am a maintainer). Someone posted a link to a fork with a bunch of goodies added. I think they just had AI implement some big features that had already been discussed and were either rejected or far future/maybe. That fork still exists but looks to be dead, as there hasn't been any new development since it first appeared. I had a good look at all the commits but I don't see any that I really want to grab as-is. Some of it looked a bit promising though.

I recommend you at least make upstream aware of your fork if there is anything in it that they might want.

Yeah Eric Raymond and open source were a bad move. Should have stuck to Free Software - as in GPL license. All that open source stuff was deliberately made corporation-friendly, which is not what's in the best interest of the code.
Permissive licensing is a large part of the issue TFA is talking about. GPL does not have those issues. All FLOSS suffers from AI ingesting the code and being able to output work-alike programs to some extent, but for now large GPL programs - Inkscape, Firefox, VLC, Blender, FreeCAD, KiCAD, the Linux kernel, etc are all safe - none of them are permissively licensed so nobody can proprietize them (is that a word?)

Unfortunately (in my opinion) the rewrite it in Rust movement also abandoned non-permissive licensing, so over time a progressively larger body of work will fall to this.

>> Probes trained to predict the outcome of future edits (before they are materialized and written on disk) achieve performance above chance up to roughly 25 steps in advance.

Are these probes effectively run in parallel? The way this reads is more about predicting a future outcome than keeping the current token relevant based on past tokens.
