dialamac··on Apple is building an operating system for health
You are being overly obtuse. The term popular vote has a clear definition in US presidential politics and the meaning of “won” the popular vote has a clearly defined meaning. That this has no bearing on the outcome of the election is a separate issue but doesn’t diminish in the slightest the meaning of winning the popular vote.

Well sugar beets excluding water content are about 85% sucrose. Sugar production and consumption dates to antiquity, long before mass western obesity epidemics, a luxury item. It essentially became a staple food in the North American diet in the 20th century.

Anyway, honey has a higher concentration of fructose so it has a lower GI than table sugar, but this difference is quite moderate (a few percent) - it seems to get overstated a lot on the web. Honey is basically refined/processed fuel produced by bees - and on evolutionary time scales it has been in use by humans about the same as sugar. Don’t get me wrong, it has chemical and physical properties that make it a beneficial sugar alternative - probably most of which is earlier satiety and therefore less consumption. If consumed in similar quantities it’s still going to make you fat. TANSTAAFL.

My grandparents are probably older than average... but the life expectancy was a fair bit shorter just 100 years ago. Most didn’t even get the opportunity to live long enough to have gastric cancer (smoked meats) or a second MI.

> We did not evolved to eat processed sugar, which is not easily found naturally in the environment

The flour you make French bread with is not found any more or less naturally in the environment than the sugar you get from cane or beet.

This whole thing about evolution and nutrition is entirely pseudoscientific woo.

If humans had to eat the same way as our ancestors (ie actual paleo, not some hipster fad diet) humanity would have died out long time ago.

The French thing makes this all the more ironic... I can’t imagine much more triumph in modern processing than the five mother sauces.

Clearly the American diet has a crazy oversupply of sugar... fructose, glucose, sucrose... at the amounts we’re talking about in the average American diet it doesn’t fucking matter (making the whole HFCS controversy always a joke).

I have a hard time believing he would have been unfamiliar with Plan 9. It wasn’t exactly obscure in the research community at the time. See the USENIX proceedings in the late 80s and 90s.

This is mere speculation, but I doubt he would have appreciated Plan 9.

dialamac··on Why do C to Z80 compilers produce poor code? (2018)
The accepted answer is somewhat true but also has some glaring inaccuracies.

The fact is that there are/were some very effective C compilers for Z80, none of them free and far from it. By the time compiler technology advanced through the 80s and 90s the market for a non commercial optimizing compiler for the Z80 and 6502 rapidly diminished. gcc has never in its history been a fantastic 8 or 16 bit compiler. By the time egcs was merged even 68k was rapidly losing relevance.

It is totally possible with modern techniques to make a very effective optimizing C compiler for Z80, but who’s going to do it? There are very few hobbyists with both the chops and the time for something with little commercial value.

The answer is correct in implying that the PDP was better suited as a CISC target for C when optimization is not done.

dialamac··on CA Root expired on 30 May 2020
Probably. It’s an honest mistake. For Gen Xers and early millennials blue m&ms are memorable for being added in the 90s with much ludicrous publicity.
dialamac··on The PEPs of Python 3.9
CPython is pretty terrible. Numpy has the concept of views, cpython doesn’t do anything sophisticated.
dialamac··on Boeing cutting more than 12,000 U.S. jobs with thousands more planned
Boeing is the only American commercial transport jet manufacturer based in the US. The US politically would never allow the loss of this - whether it be “Boeing” or some new named thing that’s basically the same. For pro-global politicians it would be a major signal of failure of American industry, for “America first” isolationists it’s an obvious problem.

Indeed, I did just that (with NetBSD long) about 20 years ago on a Dreamcast.

dialamac··on Two capacitor paradox
Model inconsistencies, unreasonable mathematical idealiazations and false assumptions are what are commonly classified as paradoxes in physics. It’s a common use of the term.

dialamac··on Guide to Concurrency in Python with Asyncio
This doesn’t sound quite right. Unless they changed something threadpoolexecutor does involve multiple OS threads, and is not single threaded. Sure the GIL puts a big limitation on parallel execution, but it is most definitely different.

For one, regardless of the GIL it is still possible to have races in multithreaded python code. You have to worry about RMW because the threads are arbitrarily preemptible at a bytecode boundary. This is not the case with asyncio.

Additionally you can release the GIL when making calls to C code. Asyncio is giving you concurrency by using nonblocking calls, you can’t run two CPU bound threads in parallel with it. But you can do this with python threads. So it’s not true that neither can accomplish more than the other.

dialamac··on Unable to deal with Chrome Extension Team, Kozmos is shutting down
I’m not arguing either. But dude, google? Google!? Its business is selling ads for corporations. A google software engineer can get a job at countless places including nonprofits sometimes making close to google money, but even if they made half that income they would be living more comfortably than 3/4s of the US.

Anti corporate soapbox or google job, please just pick one.

> including many with an anti-corporate streak.

So basically the worst form of slacktivist hypocrites.

dialamac··on Ask HN: What startup/technology is on your 'to watch' list?
No they’re underrated. We all know the stats. Driving isn’t the safest activity. Having said that there’s a lot of wishful thinking that the current state of ML can do any better if we were to just put them on the roads today as-is.
dialamac··on Python performance: it’s not just the interpreter
How much time is actually spent in the python runtime/interpreter? That python can glue some libraries together at a high level was never really in doubt.

dialamac··on Ask HN: Production Lisp in 2020?
Do you pretty much exclusively use LispWorks, or do you other tooling. I am curious to hear.
dialamac··on Ask HN: Is there still a place for native desktop apps?
There’s nothing to really block much on the aur. There are some guidelines in naming and no duplicates, no maliciousness etc that are enforced, but that’s it. But anyone can upload a build script (PKGBUILD) for anything.

If you want to see how it’s done search the package name and AUR and you can see the build script right on the website.

dialamac··on Ask HN: Is there still a place for native desktop apps?
In a fair society it should be taxed as an externality. There is a real environmental cost associated with software bloat.
