I use it to give me focus-follows-mouse and to have a large circle surrounding the mouse when i move it, to aid finding it.
jmcguckin··on Show HN: I wrote a technical history book on Lisp
Can i get it in pdf form, or at least, can i get a copy of the epub, instead of being helf hostage to a proprietary reading walled garden like Amazon. Does Nook allow you to download the epub file? But, I’d prefer pdf.
jmcguckin··on Tell HN: Avoid Cerebras if you are a founder
Didn’t Cerebras announce a deal with OpenAI recently? Perhaps they need the resources for that contract…
jmcguckin··on Dick Cheney Dead
It’s about time.
jmcguckin··on Open Hardware Ethernet Switch project, part 1
If i wanted to do a motherboard that held 16 or 24 raspberry-pi compute modules, could i connect them together using the onboard gig ethernet without using any magnetics? Just by using the gige output from the module going to a commercial switch chip.
jmcguckin··on Why 'Margin Call' remains Wall Street's favorite movie
This is a great movie. Spacey is great but Jeremy Irons is fantastic. I really like the speech where he says "Speak to me like I was a golden retriever."
jmcguckin··on Backblaze: Mounting Losses, Lawsuits, Sham Accounting, Insider Selling
I remember when my mom used to hold Tupperware parties.

I guess they could go door-to-door selling backup or maybe hold Backblaze parties…

jmcguckin··on Backblaze: Mounting Losses, Lawsuits, Sham Accounting, Insider Selling
I think Backblazes pricing model is unsustainable and expect them (and any competitors who mimic their model) to eventually fail when the money runs out. Racks and racks of disk drives use a lot of power and cost a lot to keep running. A better model would be storage based on tape; one of those large tape libraries (e.g. iceberg) with nearline disk space. Most of the data that gets uploaded never gets accessed, so keeping it on tape instead of spinning rust makes sense. Sure, there’s tradeoffs, but imagine how much they’d save if they could downsize their data center spending by 90%.
jmcguckin··on Ask HN: Why does OpenAI require an ID to use their image API?
I think part of the reason is that they want to be able to track the images back to you. Some person in the company is probably worried that a user will generate child porn like images and distribute them on the net. When the cops eventually come calling, they want to point to the user. This probably means there is a user-id embedded somewhere in the image.
jmcguckin··on Visiting Us
What’s a typical Epic installation. Does it run on a single server? A cluster?
jmcguckin··on Reflecting on 18 Years at Google
All the wood behind one arrow…
jmcguckin··on What is ‘budget Ozempic’ that’s all over social media?
Otherwise known as ‘colon blow’…
jmcguckin··on HP 15C Collector’s Edition (preorder)
Double shot keys?
jmcguckin··on The Wikimedia Foundation spends Wikipedia donations on political activism
It’s my understanding that a large percentage of hosting costs are donated by large companies like Google…
jmcguckin··on Why Doesn’t California Solve Its Housing Crisis by Building Some New Cities?
California already has several cities available for housing the homeless:

1) Eagle Mountain. Housing, Administration and ancillary buildings are already erected. 2) Salton Sea 3) Manzanar

In addition, there are several abandoned military bases that could be put back into habitable shape with minimal effort.

jmcguckin··on Kaketsugi – A technique for repairing holes or tears in fabric (2021) [video]
Wow!
jmcguckin··on Restored F80 compiler code for CP/M
Wasn’t this compiler liscenced from Silicon Valley Software?
jmcguckin··on Flexible device could treat hearing loss without batteries
An ear trumpet?
jmcguckin··on Yamaha DX7 Technical Analysis
For a number of years, the FM patent was the most profitable patent that Stanford owned. It's interesting that it was a patent from the music department - not engineering, not biotech that made the most money...
jmcguckin··on Show HN: ChessCoach – A neural chess engine that comments on each player's moves
I’d like to self host. Will this run with a gpu?
jmcguckin··on Vintage Byte Magazine Library
I’d be happy to host it for you. We have lots of space and a big connection at my work.

jmcguckin··on Video of Tesla FSD almost hitting pedestrian receives DMCA takedown
At the time the car was going to make a right hand turn, it looks like the pedestrian hadn't even stepped off the curb. I don't see the problem.
jmcguckin··on Liquid cooling next-gen servers getting hands-on
One place i worked used flourinert to cool the circuit cards of a integrated circuit tester.

Each card has a 'cold plate' where the outside of the cold plate has a brass tube brazed to the plate in a serpentine pattern leading to two quick disconnect connectors that automatically engage/disengage when the card in inserted or removed from the card cage.

The other side of the cold plate (the 'inside') has spring loaded fingers to pull the heat away from chips. We had some chips that dissipated over 100W.

This worked great - you'd lose maybe 1 drop of fluid per card insertion, etc. We used flourinert, but DI water, mineral oil or water with ethylene glycol could be used as well.

jmcguckin··on Judges reject Viasat’s plea to stop SpaceX Starlink satellite launches
As far as I know, starlink has not been subsidized by the government. They recently won an rdof grant to provide service to rural areas in the US, but this grant was received after most of the satellites were in orbit.

Musk always seems to be thinking two steps ahead, so perhaps Starlink is just an enabler for a future, more profitable product.

jmcguckin··on I wrote a children's book / illustrated guide to Apache Kafka
cute. ELI5, but with beavers.
jmcguckin··on “About one-third of Basecamp employees accepted buyouts today”
Sounds like Basecamp just got rid of all the slackers/drones...

I can see a typical job interview for one of those employees: ‘And why did you leave your last job?’

‘They wouldn’t let me waste half the day arguing politics’

jmcguckin··on Rupert Neve, Grammy-Winning Audio Industry Icon, Dies at 94
He was great in those Harry Potter films...
jmcguckin··on Anthony Levandowski Pardoned
The earlier comment implied that Bannon stole all the monies raised, when in fact, where talking about what - 10%? - diverted? There's no question that 100% of the monies did not go to the construction of the wall. From a practical standpoint, a non-profit that manages to run with a 10% overhead is very unusual. Most non-profits spend most of their money (70%+) on marketing and administration.
jmcguckin··on New Intel CEO rehiring retired CPU architects
I worked as a contract employee in Santa Clara about 20 years ago. What do I remember? The corporate infighting and the corporate paranoia (examining the contents of your briefcase and backpacks) and the IT department sniffing your internet use.
