keltor··on Principia Mathematica is modern and insightful
It was required reading for my Logics class in undergrad. Pretty sure it was also on the optionals (aka required) for my Set Theory class as well.

It's also pretty typically a part of History Of Mathematics and Philosophy of Mathematics courses.

keltor··on Arch is a gateway drug to NixOS
Arch is something a fairly non DIY user can easily conquer and use for many years and it will just work. As long as they don't choose to do anything exotic, they can use it basically forever.

NixOS is nothing like that, there's limited docs, the docs are sometimes just RTFM that links to another RTFM and oh yeah don't be afraid of breaking userspace because userspace is doing something wrong. It's fine for some of us who can of course get shit done.

Ultimately, I think some subset of Arch users who really wanted to be Gentoo users but weren't because "drama" and then NixOS scratches that itch.

keltor··on Japan: The land that doesn't need Ozempic
Americans eat 25% more calories since 1961. It's that plain and simple, no need for monsters hiding under the food.
keltor··on Japan: The land that doesn't need Ozempic
Basically it's all about Calories and Americans have added 25% to their caloric intake since 1961 when it started increasing.

Its also not really magical, they didn't just add sugar, they added meat, sugar, grains and oil (replacing butter mostly) - all together it adds up to 720 kcal extra per day per capita.

Koreans eat about 1500 kcal less per day (they are also quite a bit smaller on average so it's not 1 ot 1 of course.) Japanese eat even less (like 200 kcal less) but are also even a bit smaller on average. Both countries happily eat terrible food just as much as Americans do these days, they just eat a lot less food in total.

There's an idea that American eat out more and that the calories at dining establishments about increased about 35%.

keltor··on Satoshi – Sirius emails 2009-2011
The C++ coding style is also very much the way a Windows developer would write C++ code. Not the way a Unix-y C++ developer writing on Windows would write.

I always figured based on the code and the emails that it was an older Japanese developer. I've emailed 100s of them over the years and they do all typically write similar in English, they mix a lot of UK/US-ism, and often their English is really good, like I wouldn't know they weren't a native English-speaker until I just caught on to how they wrote. (Speaking is an entirely different issue, many of them cannot speak English in person very well or make obvious grammatical mistakes they don't make when typing.)

Windows is also very pervasive among developers.

keltor··on A woman who can smell Parkinson's is inspiring research into diagnosis (2020)
She was able to detect a person who they thought was a false positive and turned out several months later did have Parkinson's. She detected her husbands before he had signs as well.

They also found the molecule she was smelling which was expressed with sebum. This isn't entirely unfounded as they already knew about dogs smelling cancers and other various diseases.

keltor··on We need a lot more electricians
There have been attempts to use modular electrical systems, but consumers want choice and flexibility and governments at least in the US want those inspection $$$$s.
keltor··on We need a lot more electricians
Almost for sure that's what happened to the OP as he was having an external disconnect, so the entire panel got depowered + likely big lines were run for whatever he needed the disconnect for. There's sometime exceptions for Solar now that don't require full upgrades, but some cities don't give a fuck.

The US is way worst about this than most other places though. Here they inspect your insulator, lead-in wires, meter, and distribution panel and then ask what if any problems you are having (they is the power company) every four years. Mostly the electrician/contractor does the work and there's no inspection of that.

keltor··on The CPSC is on a mission that has nothing to do with safety
Finding statistical "faults" without experts in the specific narrow area of research being consulted reeks of politics.

On the subject of banning gas stoves specifically. I think 100% of everyone suspects that is going to happen at some point. Why not now?

Are we implying that gas stoves are safe? Surely this is just a straw that broke the camel's back for the CPSC and likely they didn't need much if any reason to ban them for safety reason, they do in fact pretty regularly kill people.

keltor··on On leading underscores and names reserved by the C and C++ languages
There's lots of them but long long gone are the days when the guy who's working on Network blah blah for Azure is allowed to do anything with Windows. Silos are good except when they become Ivory Towers which is what they have become. Sadly it seems some sort of modern managerial style since it infects almost every corporation these days.
keltor··on The search is on for banana ancestors
"Wiped out" is patently false. Gros Michel is pretty standard in Southeast Asia and still grows all over Central America.

Cavendish is actually still fairly susceptible to Panama disease and the Cavendish grown in parts of SEA are being pretty handily wiped out.

The real problem is the want to transport unripen bananas with thick skins to market and have them look ripe and unbruised. Bananas don't seem to want to breed pretty and thick skins.

keltor··on AirPods don't “just work”
I've used 100+ Bluetooth devices and ever single one of them had weird connection quirks. Hell every wireless protocol I've ever seen has been similar excluding some actual industrial stuff.
keltor··on Exploring System76's New Rust Based Desktop Environment
It "looks" good because so far all it is, is recreating GNOME running in PopOS while using the Rust GTK4 bindings.
keltor··on Ken Thompson's Unix Password
Actually, it's a rather perfect analogy.

People have some expectations of privacy and it's not normally considered acceptable to violate this.

Sometimes this stuff is untried in court or falls into a definite legal grey area and usually the policy is to err on the side of caution and simply assume that if something is commonly expected to be private, then it's private and should be kept so.

If we were investigating a user for XYZ and came across a file named "Personal Diary 2019.txt" or whatever, I can assure you that HR would not want us to open that file. Possibly if HR found out they'd declare the investigation tainted and want to stop it right there.

keltor··on 200k people applied for jobs at Amazon in a single week
Contrary to what the GP is saying, Glassdoor seems EXTREMELY resistant unless the review is actually fake and/or contains proprietary information. It's absolutely nothing like Yelp.

I do understand that they have their "own" system that automatically reviews posts and removes them. Sadly that hasn't worked out fantastically at my employer, they mostly remove these 5 star reviews.

keltor··on CPU Usage Differences After Applying Meltdown Patch at Epic Games
We're using KVM on OpenStack. We use a number of the services and PostgreSQL is our main database platform with our main backend platform being C++ based.

I have performance trending going back 1 year and honestly other than Postgres, the performance #s are like rounding errors. PostgreSQL is getting about a 7% hit on our databases that don't fit in memory.

We also run SAP and again we're not seeing anything. The SAP Database runs on POWER Servers, so obviously unaffected at least by Meltdown.

In our case, there was a major kernel version change, so we're just at the tail end of QC before I can release things to production to begin the rolling restarts tomorrow morning.

keltor··on Zhaoxin's x86 CPUs
It has 64 bit.

Hans started moving to Taiwan in the 1600s, then you had that big influx as the Chinese Revolution wound down.

There's also Native Taiwanese - https://en.wikipedia.org/wiki/Austronesian_peoples, they even make up about 2% of the population, I think they all want the Hans to pickup and leave their lands.

keltor··on Zhaoxin's x86 CPUs
It wouldn't really matter anyways since the Chinese have been making MIPS64 chips for more than a decade.

The current high end chip in China is actually new arch based on the DEC Alpha.

keltor··on Reading privileged memory with a side-channel
I'd bet a certain percentage of THOSE were actually lynx/links/elinks users rather than no script users.
keltor··on Linux page table isolation is not needed on AMD processors
They actually DID have hardware RAID controllers, but not like you're talking about.
keltor··on An In-Depth Look at Google's Tensor Processing Unit Architecture
There are no datacenter class Maxwell-series GPUs. They never released a version with ECC SRAM and so Amazon and Google never used them in production.

Part of the fault was GDDR5's limitations that involved trickery to make the Kepler-series work.

Pascal is coming with ECC because HBM2 comes with ECC built-in.

keltor··on Night Shift compared to f.lux
Unfortunately, it's known to decide to change that back to your actual location. Happened quite a bit, it's been one of the more annoying problems.
keltor··on False information on the internet is hiding the truth about onions
Every couple of years they seem to wipe out all these kinds of things, so you don't get them, then companies come up with new ways of writing their pages so that they all show up again.

Remember when we had all those spammy answer sites that dominated Google searches for almost any technical question?

keltor··on OpenEMR: Electronic Medical Records and Medical Practice Management Software
Unfortunately most of the time you end up having to individualize so much data structure for each deal it's a gigantic pain.

I think the one nice thing about the dental world is that "for now" there are still far more independent entities without the ties into hospital groups like doctors and practice groups all have.
keltor··on OpenEMR: Electronic Medical Records and Medical Practice Management Software
Unfortunately with the consolidation into medical "groups" that has been going on among doctors and with the hospitals offering "deals" along side those vendors they use for the doctors to adopt them, a lot of doctor's groups have adopted whatever system they are most integrated with's EHR.

There's a ton of slimy dealings going on sadly.

keltor··on OpenEMR: Electronic Medical Records and Medical Practice Management Software
Epic, Cerner and Meditech are the largest EHRs and they combined control just about 50% of the market. Epic and Cerner tend more towards the Academic hospitals and Meditech and McKesson (#4) tend towards the Commercial hospitals.

There has also been a ton of incentive payments from CMS that have almost exceeded the EHR industry as a whole.

There have also been quite a few big switches from the 90s to today, a bunch of them from Meditech/Epic/Cerner to others, so it can definitely happen.
