Some additional discussion at NextPlatform. It's an all-CPU system, but the CPUs have Scalable Matrix Engines on them, and a lot of cores, adding up to something that resembles GPU…

Interestingly (to me), I learned about the "ridgeway" just a few days ago, from Jim Leary's episode on the "History Rage" podcast, where historians vent about popular historical mi…

Slightly OT, but if you are interested in this sort of thing, William Dalrymple and Anita Anand co-host the Empire podcast, which has many episodes and guests and recommended readi…

I think yes? Kinetic energy scales as velocity squared, so a car at 100 MPH has 4x the energy of a car at 50 MPH. But in the 50 MPH scenario there are two cars, so the total energy…

Vaguely reminds me of the Adapteva Epiphany RISC multi-processors from the old Parallella Kickstarter project, and presumably others, but that's the one I played with for a while. …

Lovely. "The Mythical Man Month" was a recommended supplementary text when I was in undergrad computer science, and it was well worth the read, especially for me -- I have a tenden…

I'm not sure if this is a fair question or not, but suppose I have a 6-byte blob I want to send. I can pad it out to 8 bytes, use this scheme to encode it, and send it. Then I want…

I noticed that too. I was also surprised that they called out the complexity of EV drivetrains (and charging systems, but I don't know anything about those) as a factor. My prior u…

Sorry for the late reply, but no to all three. We lived in Chicago when this became a thing. My grandmother did live in Denver (well, Aurora) though.

The article being from 2011 is perhaps why it can be as long as it is without mentioning "Coarse-grained reconfigurable arrays", or CGRAs, which, at least as of 2019 when I learned…

First hit for me is the Bluesky social media logo.

I love this, it's got that "technical correctness is the best correctness" vibe going on big-time, and it will probably change the way I see that slice of the world. Butterflies lo…

I learned about this after stumbling across the "Museum of Jurassic Technology" in Los Angeles, several years ago. It was pretty clear from the outset that it wasn't a "real" museu…

Definitely not my field, but a colleague of mine in grad school who was doing GR stuff was convinced that black holes didn't have singularities. As I recall (it was a long time ago…

And in French, in particular, it's named after India, but the word is an abbreviation and contraction of the phrase "poulet d'Inde" ("Indian chicken"), which got shortened to "dind…

Even more radical proposal: Make this restriction on senior corporate officers. Your salary can depend on how well the company does, but your investment portfolio depends on the br…

On the one hand, I am not surprised -- at my workplace, we only ever had one Itanium system, an SGI Altix 3000-series computer. It was kind of niche even when we bought it, and cor…

These are interesting and fun. Each issue follows a particular theme (youth, risk, energy, time, etc.) and I occasionally wondered if they would run out, but they seemed to keep go…

Commander Koenig.

The article implies pretty strongly that there is an ozone problem that's independent of the smoke problem, so the proposed ozone controls are still necessary, and that erasing two…

This is very cool, as are a lot of older algorithms, and some newer ones. Probably mechanical computers had lots of under-the-hood optimizations that would be interesting to dig in…

Not mentioned in the article, but if you add the key to your agent with "ssh-add -c ", then whenever the key is used to connect to another machine by the agent, the agent will prom…

Selecting what metrics to use for categorization in a scientific study is a subjective choice, and searching for objective measures can de-contextualize your data.
