AMD says transistor tech will keep Moore’s law alive for 6 to 8 years

bob, mon!

Ironic quote in the sub-headline

...considering that Moore's original observation referred to lowering the cost of transistors. Here's a quote from his 1965 paper (see e.g. https://montcs.bloomu.edu/~bobmon/PDFs/Gordon%20Moore.Law.pdf)

The complexity for minimum component costs has in-

creased at a rate of roughly a factor of two per year (see

graph on next page). Certainly over the short term this rate

can be expected to continue, if not to increase. Over the

longer term, the rate of increase is a bit more uncertain, al-

though there is no reason to believe it will not remain nearly

constant for at least 10 years. That means by 1975, the num-

ber of components per integrated circuit for minimum cost

will be 65,000.

I believe that such a large circuit can be built on a single


After lunar orbit trip NASA's Orion capsule is on its way back home

unbelieveable accuracy

"Orion carries a trusty bit of equipment leftover from NASA's Space Shuttle era, its main engine, capable of providing 6,000 pounds (over 2,721 kilograms) of thrust "

Other sources suggest that the Space Shuttle's main engine provided as much as 470,000 pounds of thrust. One document does mention the "Orbital Maneuvering System Engines" producing 6,000 pounds of thrust.

Northgate keyboard

I still have a Northgate Omnikey from three decades ago. Great keyboard, even without the Windows key :-] Sadly, I can't get it to work through my KVM switch.

Weighs a ton, should be able to stop a small-calibre round at least.

Bullseye! Debian-based Raspberry Pi OS scores an update with 'less closed-source proprietary code'

bob, mon!

Re: Back to the Past

> Or try the unofficial Debian arm64 edition.

I'm sticking with 64-bit RaspiOS beta for now. I have to maintain both RPi3 and RPi4 with their differing boot methods, so bringing the Debian release up looks daunting. Or maybe I'm lazy.

A compromising document

"...an office automation suite compromising the usual suspects: word processing, spreadsheets, email, database and so on."

Is this the office automation suite for scandal mongers? Or just a lot of apps that are vulnerable to zero-days?

Microsoft doles out Office Long Term Servicing Channel for cloud refuseniks

Office XP works as well as it ever did, and does a good 90% of what 90% of the users actually want out of a word processor, spreadsheet, and presentation app. And Outlook on the Web does the rest.

Re: Astrophysicists love approximations

Way back when I was in college, I was told that an engineering equation was "good enough" if it was accurate to 3 decimal places; a physics equation was good enough if it was within an order of magnitude; and an astrophysics equation was good enough if the units came out correctly.

That was in the days when slide rules ruled....

Yeah, that Zoom app you're trusting with work chatter? It lives with 'vampires feeding on the blood of human data'

bob, mon!

I can only hope that this data slurpage applies to the free version. My school system (consisting of 14 state universities) has chosen zoom as its official standard teleconferencing software. I have zero options to change to any other platform. And even if I could, getting people to use zoom was and is an exercise in on-the-fly training, and anything else would have that problem and no official support.

Well, maybe the corporate legal team actually did due diligence and checked out the Ts &Cs. Who knows?

Astroboffins discover Sun is surfing on 9,000-light-year gas wave that acts as Milky Way's stellar nursery

bob, mon!

... Is it a static wave or does it undulate? ...

Quoting from the abstract:

"Remarkably, the new structure appears to be undulating and its three-dimensional structure is well described by a damped sinusoidal wave on the plane of the Milky Way, with an average period of about 2 kiloparsecs and a maximum amplitude of about 160 parsecs."

Rural Pennsylvania. Rural (western) New York, rural Vermont, New Hampshire. Rural Ohio, Indiana, Illinois, etc.

I'm 2 hours from New York City (at 70 mph), and 4 hours from Pittsburgh. Lots of small towns in between, but lots of farms, forests, state hunting lands and the like as well. My nearest neighbor is across the road, but the next nearest is 1/8 mile away. No cable out here, never mind fibre. Some days "IP over avian carrier" seems like a viable option.

"Can you do 3Mb up with a low bandwidth modem on a long phone line?"

AHHHAHAHAHA*kaffkaff* No.

I get less than 100 KB/s (so 800Kb/s) up on a good day... and Verizon DSL doesn't give me good days. I just now got a 44.1KB/s upload of a 300MB file. Yawnnn....

Of course, a true "low bandwidth modem" would be the 300-Baud unit I started out with, back in the previous millennium.

Seriously: do-while versus while? (Versus for???). Look at the machine code. A decent compiler generates the same code for any version, and it's the most efficient implementation the architecture can provide. Those higher level constructs are so YOU, the programmer, can remember what you meant 6 months from now.

That's all you can say about the paper? I met it in grad school in the 1980's, and still have my copy. It's delightful! Here's an excerpt:

"Encouraged by this success, as minor as it is, the Blefuscuians tried to pull another fast one. This time it was on the VAX, the sacred machine which all the Little-Endians worship."

Go fourth and multi-Pi: Raspberry Pi 4 lands today with quad 1.5GHz Arm Cortex-A72 CPU cores, up to 4GB RAM...

bob, mon!

Re: Ethernet

True GigE will be a boon for beowulf clusters running MPI or whatever over Ethernet, as the node interconnect is a bottleneck.

I just built up a 4-node RPi 3B+ cluster for class use, now i need to justify getting 4 new RPi 4's. Also glad to hear that the boards can run on 2.5A, since the cluster doesn't have any peripherals and the current generation of multiport USB P.S.'s max out at 2.5A per port.

Next step - find out whether 64-bit Devuan will run on the new board.

"Latency has also been lowered in the 9300s from 92μs/21μs read/write to 86μs/11μs."

Really? Read latency is worse than write latency? I am surprised, would've expected it to be the other way around.

bob, mon!

Thank you, Lenovo?

Their list of laptops includes the T440s - "not affected", and the T460s - "affected". So where does that leave my T450s??? "Sort of affected"? "Deeply moved"? "Concerned, but not really bothered"?

Fortunately, Lenovo also listed the relevant firmware numbers, and a reboot and BIOS check suggests that I have an older, unaffected version of the ME firmware. Sure wish they'd included my machine in the list though, makes me feel somewhat abandoned.
