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-scale parallelism, so it is accelerated in that sense,

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 misconceptions. For the Ridgeway in p

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 reading covering lots of ancient history. I'm not affiliated

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 dissipated in the 50 MPH head-on collision is half that of

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. I'm not sure how this project's interconnect

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 tendency to get hung up on the cool tools and fun method

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 the receiver to understand that only the first 6 bytes

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 understanding was that EV drivetrains are significantly

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 about them, seemed to occupy a good middle ground

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 loom weirdly large in my life, at one point man

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" museum, and one should not take the labe

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), it was mostly an aesthetic preference, he felt it wa

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 "dinde".

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 broader market. I mean, as long as we're using investment

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 core-for-core, the Itanium CPUs were slower than their competit

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 going. Articles were an interesting mix of deep dives and shor

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 days of bad air quality by attributing it to wildfire

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 into. It reminds me of e.g. the CORDIC algorithm, used to calc

Not mentioned in the article, but if you add the key to your agent with "ssh-add -c <key>", then whenever the key is used to connect to another machine by the agent, the agent will prompt (on the machine where it was initial

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.

You might want to give this more thought -- on reading the piece, my take-away was, "this guy is a half-step away from inventing the slide rule". IMO, what the slide rule does is replace the memorization of squares and roots, or o

We have a related issue in US civilian Federal agencies, where the IT security posture has been moving for some time to a formal compliance scheme. The idea is that to manage things at scale, it's desirable to have certified solutions,

Seconding this, for sure. "/usr/sbin/sshd -T" (T for "test") has been a life-saver more than once. My strongest version of this is that any application that manages any state should be able to report o

I remember writing a GTK extension widget many years ago, and yes, it was very much like this. The macros end up making your very own hand-coded vtable-equivalent, so that function calls get dispatched to the appropriate point in the inheri

I recently read what you might call an "apprecation" of the Sextant, the navigational instrument -- it was a mix of a travelogue of the author's trip across the Atlantic, a narrative history of nautical navigation, and a tech
