petesoper··on Fable turned reMarkable into Tom Riddle's diary from Harry Potter
A new high water mark for R T F A.
petesoper··on JuiceSSH – Give me my pro features back
"I guess I'm asking for a "Convince me to try it" style review of juice" Notice this is about juicessh becoming unusable and no longer having any support. That should satisfy you.
petesoper··on The recurring dream of replacing developers
90 years ago there were about seven million farmers in the US. There are now less than two million.
petesoper··on Building an IoT Notification Device from Scratch
When I got to auto[ssid, etc in main.c it became clear the sophistication/excursion from the typical Esp32 code centerline is at many levels. Thanks for sharing!
petesoper··on The Limits of NTP Accuracy on Linux
The OP says early he only needs 10us.
petesoper··on JEP 483: Ahead-of-Time Class Loading and Linking
Sweet!
petesoper··on Robert Dennard, DRAM Pioneer, has died
"By the early 1970s, DRAM was standard in virtually all computers."

Perfect bullshit.

petesoper··on A RP2040 based DECstation 3000 emulator that can run DECWindows
What boggles my mind is the notion of running an RP2040 at 300mhz.
petesoper··on The t-test was invented at the Guinness brewery
54 years after I was mystified trying to parse the use of "student" for this, here is the answer. Cool!
petesoper··on Gordon Bell has died
Gordon was one of the founders of Encore Computer and my first encounter was in Mass at the point Hydra, Resolution, Foundation and the other component company acquisitions were melding together. I remember being gob smacked by Gordon having a little Vax as his PC and only later came the "well of course he does" realization. He was keen for us to get on to Arpanet and that happened before the end of 1984.

If you're in 2025 we have a few questions for you.
petesoper··on ENIAC programmer Jean Bartik's Amazon book review
Closing line was "I'm glad this book was written."
petesoper··on The cancer that some doctors don't want to call cancer
There is a solution for chronic cases like this: a manually operated valve that stands in for the sphincter. Some of the guys in my prostate cancer support group have described this as "life changing".
petesoper··on Hughes Elevates Rural America's Internet Experience with the New Hughesnet
These satellites are in geosynchronous orbits. The minimum latency of an interactive exchange with something on the internet is a major fraction of a second. One might think of something like ssh being almost perfectly unusable, and it is, but consider how much back and forth there is with web pages being rendered these days. Having lived with synchronous satellites for a couple years I'm here to tell you they absolutely stink for much beyond watching streamed content and downloading files. Something like Pi Hole to avoid wasting time with junk would be valuable in this setting and doubly so if Pi Hole's name server caches effectively. The basic principle involved with these services is statistical multiplexing with a constrained composite link speed. Translated, that means the more subscribers there are the less bandwidth during busy times. So although Hughes touts up to 100mbs down you won't see that unless you use the system when most are asleep. Finally, if this system is truly advanced it will support alternate ground stations. Without that you get the astonishing experience of blackouts when thunderstorms visit the ground station.
petesoper··on 1-bit CPU for 'super low-performance computer' launched – sells out promptly
Because the term "central processing unit" has many connotations. This thing with the label is missing too many essential parts. It's like calling a box that slides down hill with enough incline a soap box derby car.
petesoper··on 1-bit CPU for 'super low-performance computer' launched – sells out promptly
1-bit CPU? Bullshit.
petesoper··on Wasabi linked to "substantial" boost in memory, Japanese study finds
Scratch the price remark as I just caught up to the "99% is fake" data. Sigh.
petesoper··on Wasabi linked to "substantial" boost in memory, Japanese study finds
Real wasabi powder runs vaguely $5 an ounce. Wasabi is a different species than horseradish. The taste is quite different.

petesoper··on Ask HN: What paper/print magazine do you still buy and read?
I look forward to reading The New Yorker every week.
petesoper··on The Unforeseen LSD Overdose of 1972
"All eight individuals had plasma levels of 1000-7000 μg per 100 mL of blood plasma."

Those were the gastric concentrations. Blood concentrations were about 2 to 25ng/ml.

How does he cool those wafers?
petesoper··on John Backus (1924 – 2007) [pdf]
Backus-Naur form was a great help to me in the 70s and 80s. Thanks, John.
petesoper··on A novel ultramicro supercapacitor with ultrahigh charge storage capability
Based on the article scaling would require a lot of hand eye coordination!
petesoper··on One man’s quest to revive the great American vacuum tube
Eimac, founded before WW2 but now some division of some corp, is the gold standard for amateur radio amplifier tubes and is still used by governments. They developed technical advantages while making a lot of radar tubes during the war and amateurs scooped up the surplus and later became regular customers and then commercial suppliers like Collins designed them in. They were part of Varian for a while and make modern very high power klystrons among other things.

He delivered it to the fourth estate and that's progress.
