CobaltFire··on NRC issues first U.S. construction permit for a BWRX-300 small modular reactor
This is a 10th Generation Boiling Water Reactor. Here's some relevant links:

Interesting point: no pumps; convection flow for 100% of the operational envelope.

CobaltFire··on Alan Kay's answer to “Did the ENIAC have a BIOS”?
Typically daily. They were used for troubleshooting and repairing military avionics. They survived decades onboard ships, etc. They got temperamental in their later years, but we kept them going.

If you have any interest you can search up the (sparse) information on the AN/USM-484 Hybrid Test Set (or System).

CobaltFire··on Alan Kay's answer to “Did the ENIAC have a BIOS”?
The Harris 100 launched in 1978 still used a bank of toggles for initial load.

I was operating and maintaining several until about a decade ago.

CobaltFire··on EV Sales Are Booming in Europe with Gasoline at $10 a Gallon
We picked up a used 2022 Leaf S+ a while back and it's been amazing.

Also just about the only shade tree mechanic EV. Even swapping a battery is doable by the typical car guy. Rebuilding one isn't much harder due to no cooling.

CobaltFire··on AI-generated posters don’t have to be horrible
Sorry for the late reply:

I'm in Japan more than a month out of the year, as that's where my wife's family is. At least in that area, which I just returned from, I didn't see anything but the usual food displays that have been omnipresent for decades.

CobaltFire··on Excel now supports multiple values in a single cell
When I did Process Improvement we used MiniTab for this.

I honestly was not a fan of that program and would have loved to be able to use Excel, but there are so many statistical things you just can't do in it.

CobaltFire··on Ask HN: Who's still keeping a DOS machine up because the business depends on it?
Having worked on nuclear plants (as a reactor operator) around that time this doesn't surprise me in the least.

Thats far more advanced than the systems I worked with, one of which reported rod position via resistance measurement on a brushed cylinder (one for angular and one for depth).

Cleaning and calibrating those was a constant maintenance item every time the reactor was shut down.

CobaltFire··on Ask HN: Who's still keeping a DOS machine up because the business depends on it?
I had to keep a disturbingly old machine with GPIB running until a few years back. They are still in operation in Australia (who we sold them to).

It was a test/repair bench for military aircraft avionics, with the only flying platform left using it being the legacy F/A-18 (A/B/C/D). Harris H-100 minicomputer hooked to an HP terminal and several full racks of GPIB test equipment with half of a rack of solenoids for switching between stimulus and response and which pin.

Not what you asked, but the question brought back memories.

CobaltFire··on Pentium II at 600Mhz with Voodoo 3 Emulated on 86Box with M6 Mac Mini
Played a huge amount of Quake Grapple on my Voodoo 2 12MB over a 28.8 modem back in high school.

That brings back some memories.

CobaltFire··on AI-generated posters don’t have to be horrible
Given that any advertisement with AI generated food would be illegal there I don't imagine you have to avoid very many!

I just got back from a month there and recall perhaps 2 posters that may have been AI. I actually ran into several public art exhibits as well.

CobaltFire··on Nike exits the S&P 100 after 18 years and a $200B market-cap wipeout
Ran in Asics Gel Kayanos for 20+ years and I'm in Hokas now too.

I had wondered how well that would work; thanks for that input!

Something to keep in mind that a lot of simmers (DCS specifically) don't get when they want to jump into VR:

Once you hit the advanced 3rd Gen or any 4th Gen fighter or attack aircraft (essentially anything where you go "heads down" for any significant portion of the aircrafts mission profile) VR becomes more of a liability than an asset.

For those aircraft being a pilot is secondary to being a systems operator.

Think of an F-14; you have the front seat who would want to be in VR because they fly the aircraft, but the RIO would NOT want to be because they have very little need to be, especially since it makes interfacing with their mission systems so much harder. AH-64's are the same split.

Now if you are the sole person in the aircraft and need to do both missions being able to operate the systems fluently and smoothly via dedicated interfaces FAR exceeds any benefit from being in VR.

I've done it all, and I far prefer flying in VR. But for accomplishing complex mission profiles multiscreen with each being an MFD and a rich control set far beat that immersion.

Perhaps the best mix is using a curved UW and trackir plus dedicated MFD screens. Once you get that setup its amazing for that advanced capability set.

All of this assumes you want to use the full capability set of an airframe, or use an attack profile at all. If all you want is to use them for A2A, then VR is wonderful as long as you have a full HOTAS set, understand the preset modes on everything, and memorize the controls and alternate control schemes properly for BVR to close in conversion, countermeasures, etc.

I use my RP6 (and RP5 previously) quite a bit. Its amazing what those devices can do nowadays.
CobaltFire··on How to buy a good car for $1000
Even Leaf batteries can be fine. A used Leaf might be the best deal going right now due to everyone being afraid of the battery, but if it hasn't been fast charged a ton its fine. Specifically the second gen "plus" models are great due to the larger battery meaning they have less wear.

Its also, by far, the easiest EV to swap a battery on yourself. It might be the only one you can reasonably do in your driveway. As its 8 bolts, 3 plugs, and a quick ECU flash to get a new one going. Its also cheaper ($8k last I looked, for the 62kw model) than any other EV to swap the battery due to the lack of cooling.

Not the perfect EV, but maybe the perfect shade tree mechanics EV.

CobaltFire··on The car industry A/B tested selling a car with and without CarPlay
As a counterpoint:

Telluride/Palisade causing fires because they cheaped out on the current/torque sensors in the drive motors for the seats.

ICCU failures across their current EV platforms. No fix planned last I heard.

It hurts me to point this out because I really, REALLY like where their cars are going. Their new van is EXACTLY what we want, and I'd love an Ioniq 5N.

But those failures are critical and speak to a very deep engineering culture issue.

CobaltFire··on Flock used >100 times to track veteran who recorded traffic stop
As a veteran I agree, with a significant caveat:

Generally those who support the police in general (especially those with the thin blue line American flag displayed somewhere) espouse support for veterans. The clash of a veteran operating legally with police operating illegally helps foster cognitive dissonance and disentangle these two institutions in their mind.

In other words these types of articles are helpful for causing those individuals to confront the issues in their belief structure.

I use them this way all the time with my parents, as they continue to insist that I (a retired Navy vet) should mindlessly support the police. They are not interested in the LONG history of those two populations clashing.

CobaltFire··on I think the military commissary's freezers were hacked
Nothing I shared is, in any way, even close to something I am concerned with sharing.

This type of wargaming scenario is literally stuff they give to brand new kids out of high school to get them thinking. It's not anything close to "loose lips sink ships."

CobaltFire··on I think the military commissary's freezers were hacked
Can't recall them going offline island wide when I was there (given there are two on not quite opposite sides of the island). I do recall one having downtime when the other was up and having to deal with that.
CobaltFire··on I think the military commissary's freezers were hacked
Not really relevant but a fun anecdote:

I can't speak to how much cargo was on board, but I did a Hawai'i to Guam leg on a C-17B that was carrying palletized cargo.

One of my better Space-A experiences. Crew was great, flight was smooth. I preferred it over the KC-135 leg, despite the more spartan conditions. The aircrew let us toss out sleeping bags and packs in the aisles between cargo and get some sleep.

CobaltFire··on I think the military commissary's freezers were hacked
I didn't mean to imply that this would hit Hawai'i as hard as Guam, just that it would be one of the more effective places to hit with a DeCA supply chain attack.
CobaltFire··on I think the military commissary's freezers were hacked
As someone who spent over 20 years active duty, and spent a ton of my career in the IT, security, etc. side of the house:

Unlikely to be a hack, more likely to be a misconfiguration or update sent incorrectly.

That said, the timing of the disclosure and the issue are rather concerning.

Regarding the highest value targets to hit with an attack like this, you would want to target Guam, Hawai'i, and other isolated overseas locations where this would have ripple effects in the local economy. Guam specifically would cause catastrophic supply shortages, since DeCA probably supplies around 50% of the groceries on that island (that's a WAG based on my time there).

CobaltFire··on Intel's Wildcat Lake
The Dell XPS 13 with the intel 5 320 (Wildcat Lake) is getting really good reviews.

Looking at benchmarks for the 320 vs the 322 is enlightening, as the 322 is essentially the same chip but as a full Panther Lake. So the same 2P+4E+2Xe3 setup, but without all of these optimizations. You get twice the memory bandwidth and TB4 as the main consumer facing factors.

CobaltFire··on Those of you who are daily driving Linux, what are your other devices?
I'm actually in the situation of looking to exit the Apple ecosystem to an entirely Linux one.

If you look at my post history here I lost my entire Apple account due to them assuming my purchase of a 128GB Studio was fraud, and was fortunate enough to escalate to the right office to fix it.

Couple that with the age attestations coming down the pipe and I'm thinking that it's time to go ahead and complete my transition. I love the hardware, I am productive with the OS, but enough things are pushing me away that I think it's time to go Linux for the computers and GrapheneOS for the phone.

I'll have to unload the Studio, which is annoying. I have no idea what to replace it with in the Linux space. I love that machine.

CobaltFire··on I, for one, can't wait to join the permanent underclass
I'm not sure I believe in this, but I certainly want to.

There is a certain logic to this, and it's not certain it won't go this direction. But creating a solid society for the masses so they don't revolt isn't what most of the out of touch tech billionaires aspire to, from their own public comments.

CobaltFire··on AI boosted homework scores, then exam scores dropped: study
Naval Nuclear Power School had (maybe still does) this model 20 years ago as well. Pass rate for my class cohort was 28% over the entire 2 year pipeline.

We didn't call them retch sessions, and they were taught by the instructors though. We also were encouraged to peer tutor and since we were all restricted to one building the homework was always group work allowed.

Also had badges to track time spent in the building for required study hours, though some people gave up and just slept at their desks when they started sliding down the grade scale and the hours racked up.

Generally I think I did 30 hours of studying/homework (went up and down depending on what was being taught, but was around that) a week (for 12-15 hours of actual lecturing), with some of my friends putting in 50% more. Generally the only day we weren't there was Saturdays. Most of the day Sunday was usually spent in class preparing for the next week.

CobaltFire··on Site removes all the clutter from recipe videos and gives just the recipe
How do these options deal with translation of other languages?

I can do it manually, but was curious if any send it through any of the translation engines.

Specifically my wife has a TON of Japanese recipes that I want/need to translate so I can use them. I can do it manually but doing it automatically would be awesome.

CobaltFire··on Why I've tracked every single piece of clothing I've worn for three years
I have also settled most of my wardrobe on Uniqlo and Patagonia. I have some other stuff, but over 80% is from those two companies.
CobaltFire··on Two wheels, a few tradeoffs, and gas prices
Rode for nearly 100k miles before giving it up (had a 100 mile/day commute, plus leisure).

Too many close calls, and since giving it up lost five coworkers to accidents.

Still miss it all the time, but it's just not worth the risks. I don't even bicycle on public roads (in the US; I do in Japan) any longer due to too many close calls and several injuries in my social group.

CobaltFire··on Danube's record low levels force shutdown of Hungary's only nuclear plant
Probably me. I wrote that on the train...
