I thought this was excellent (in all ways) but particularly for your question: https://www.youtube.com/watch?v=UYW1lKNVI90

mikeInAlaska··on A 1.9 solar mass neutron star candidate in a 2-year orbit
The diameter of a neutron star, despite its mass, typically ranges from about 20 kilometers (12 miles) to just under 30 kilometers (about 18 miles).
mikeInAlaska··on Ask HN: How can I back up an old vBulletin forum without admin access?
When some of my favorite google groups forums were going away, I wrote a perl scraper that started grabbing materials from my groups. Eventually Google perceived it as unwanted or suspicious contact, and shut off access to google for the entire company of 2000 I worked for at the time. Fortunately this was on a timer, but I was sweating bullets.
mikeInAlaska··on How did the tiny Alaska village of Chicken get its name?
I went to Chicken a couple years ago hoping to photograph Mountain Bluebirds, but they never showed. There were very cooperative Phoebe's though and after watching them for a long while, I saw that one had a real pattern to his hunting that involved this giant multi-story gold dredge. It would always fly out of a hole in a certain window, and eventually go back in a separate path. I am sure it was feeding babies inside that giant dredge somewhere.
mikeInAlaska··on How thermal management is changing in the age of the kilowatt chip
The low voltage power rails on consumer Ryzen and Intel chips exceed 100 amps.
mikeInAlaska··on Skaters glide across rare Alaska 'ice window' [video]
Possible, but also possible that a bunch of us live here, hike every week, are familiar with the conditions and know that the deep freeze is almost always preceded by snow that keeps this from happening.
mikeInAlaska··on M51: A Feast for the Eyes
Actually, after taking a second, third and fourth look at these, and as a backyard astrophotographer for 18 years, I'm going to say these actually are all individually resolved stars and clusters in M51. Clearly in this https://cdn.esawebb.org/archives/images/large/potm2308b.jpg

You can tell they are M51 stars, but that there are just a handful of bright, HUGE foreground Milky Way stars in the shot.

Especially considering the Ursa Major location of M51 well outside of our own Milky Way plane, there isn't a ton of foreground stars lying on the galaxies compared to other galaxies seen through the plane of our own.

When I photograph M31 Andromeda, which is hugely closer, with my 8 inch refractor, you can just start to see the resolution of these extra-galactic large clusters, as in: https://pbase.com/mclemens1969/image/128625703/original

So this seems right that this huge aperture scope would resolve in M51. Just wait until they shoot the large clusters in M33 and M31 !!

Here is my own M51 https://pbase.com/mclemens1969/image/154398728/original

mikeInAlaska··on M51: A Feast for the Eyes
You gotta be kidding me. Are those the stars of M51 individually resolved all over the image?
mikeInAlaska··on Nanofiche: Small Storage, for Forever
When we reached the Moon in 1969, could we have read it?
mikeInAlaska··on Dumpster Tektronix 2465B Restoration
It may actually prove to be the opposite case as the capacitors in these old scopes self destruct and eat their own circuit boards and surrounding components.

I have a Rigol and an Agilent over 10 years old now and going strong. Honestly though, my Agilent overheated once and destroyed its own SMPS. This was terrifying given the price of the scope (and at the moment, just knowing -- it was dead and smelled like an electronics fire). I now have a circulating fan on my scope shelf moving air behind and across all my bench equipment.

I replaced that Agilent SMPS for $150? and then got a 2 year service plan for another couple hundred dollars.

The latest Rigol prices are pretty expendable, $299!! but I suspect they will be running for quite a few years.

mikeInAlaska··on Intel Xeon Max 9480 Deep-Dive 64GB HBM2e Onboard Like a GPU or AI Accelerator
I have a Klein Torque screwdriver. Holy cow have they become expensive in the decade since I bought it.
mikeInAlaska··on Intel Xeon Max 9480 Deep-Dive 64GB HBM2e Onboard Like a GPU or AI Accelerator
What a beast. It doesn't apply much to my life, but I did notice one thing that would have been nice on several builds in the past. The torque for the heatsink screws is specified in exact lb/feet.

I have made builds in the past where you had to judge, tight enough? I thought it was unsettling. I believe my last couple builds had a more cam-lock feel to the heatsink though where it was tightened to a point where it had an obvious force-threshold stop to it.

mikeInAlaska··on 95 bits per second
I remember working for hours and hours, failing, to get a 32kb transfer to work between two Commodore 64's with 1650 Automodems. I wish I could remember the app, it would be a nostalgia overload to see a screenshot of it again.
mikeInAlaska··on Why do cats love tuna so much?
Outside of Pate' style catfood, it seems my 15 year old Calico will only eat one thing. Cane's Chicken Strips. (A piece of the white meat, with the breading torn off.) She smells that arrive and goes crazy waiting. Even making styrofoam box noises before its opened will have her bouncing around in anticipation. She will only eat a couple pieces, but it's the most exciting time for her.
mikeInAlaska··on Railway Safety Posters (2022)
I remember a Thai train slowing to a near standstill, followed by an excessive tilt to the side for a couple car lengths of movement, then back up to speed.

Also remember lines of Thai people being stopped by a guard with a machine gun for searches while my pale colored wife and I were waved right through into the train station.

I would like to go back to Thailand it was a fantastic vacation.

mikeInAlaska··on JWST spots giant black holes all over the early universe
Now imagine that the Chandra telescope has a 1.2 meter diameter aperture that those 19 photons passed through.

That represents 1.13 square meters of light collecting area, peering into that expanding spherical wavefront at the point where it is 26+ billion light years in diameter.

That would be a sphere with a surface area of 2,123 square light years. I wonder what it would add up to if you had the 19 photons for all those other 1.13 meter chunks of area in one place.

Speaking for myself and my coworkers, the numbers required for software engineers to pass will need to be set differently.
mikeInAlaska··on Microsoft opens MIDI 2.0 repo
Thinking back about it. I believe the MIDI specs were in the Roland TR505 drum machine docs
mikeInAlaska··on Orca rams into yacht near Scotland, suggesting the behavior may be spreading
I have seen ball lightning here in Alaska. One time, at night. Distance maybe 120 feet away. I watching a glowing orb perhaps 3 feet in diameter drift from the front of my parents garage towards their house before disappearing. An absolutely crystal clear view. I was on the phone with my wife at the time and describing the event to her, it was absolutely chilling to see ! I have never seen anything like it before or after. I should have ran down there and seen if I could sense any after effects, but quite frankly, I was terrified.
mikeInAlaska··on Microsoft opens MIDI 2.0 repo
My final project in a 1989 Electronics class was a MIDI interface for the IMSAI 8080 PC. I had various instruments mapped to each of the red/blue switches. Now thinking back about it, I wonder how the heck I got any information on MIDI specs without the Internet.
mikeInAlaska··on Microsoft opens MIDI 2.0 repo
MIDI 1.0 is 38 years old, I wonder if that is some kind of record for a protocol standard. But, what about the years between with MIDI over USB? Is that fairly called MIDI 1.0 still no matter the transport mechanism?
mikeInAlaska··on Arduino Uno R4 WiFi
I have had great luck running ESP32 apps with the Arduino framework. Everything I have tried works. Admittedly I am only using GPIO, SPI bus displays, I2C sensors and displays, WIFI web servers serving REACT apps, WIFI posting to other web services, and ESP-NOW layer 2 direct WIFI connectivity. But this stuff has been flawless.

p.s. the ESP32 dev modules suck and brownout randomly with WIFI usage. I use my own PCB and put fat tantalum caps feeding the modules.

mikeInAlaska··on Venus is not Earth’s closest neighbor (2019) [pdf]
Mercury by average. I've wondered in the past it we could land people on Mercury... at the right distance from the sunset terminator where the surroundings had cooled to, say 21 degrees C, (70F). With a 1408 (Earth) hour day, the landing party could stay for quite a while before needing to relocate again towards the terminator, or leave.
mikeInAlaska··on First up-close images of Mars’s little-known moon Deimos
I remember sitting on my front deck with my telescope watching Mars for a couple hours. The local atmosphere settled and the planetary features and colors were amazing. After a while I kept noticing a speck appearing and disappearing off the edge of Mars. After an hour it had definitely moved substantially. I ran in and checked my observatory software and it was Deimos !! Imagine that, a 7.7 mile diameter object seen visually from 43 million miles away.
mikeInAlaska··on Webb confirms its first exoplanet
Interesting choice for the first Webb exoplanet at 41 light years distance. There are 11 stars within 10 light years of us. Does their choice mean that none of the closer stars have systems that are edge-on to us?
mikeInAlaska··on Ask HN: Anyone else suffering from tinnitus?
I had a fingernail infection that turned into cellulitis in December 2021. Doctors prescribed doxycycline and then bactrim when it failed to resolve. (This fixed the infection.) Shortly thereafter my ears started ringing 24/7 and it has not stopped in 2022 whatsoever. It turns out these drugs have a reputation for this. I think I would have rather amputated my finger. However, I would have required antibiotics for that also : )
mikeInAlaska··on 1M Watts of RF – How the FM Supertower Works
I was surprised to see such sloppy/risky wiring for the Internet hookup along side such fine RF engineering.
