Not my field, but I'd be surprised if this was an iron issue; the timescales don't match up. I wouldn't be surprised if magnesium was an issue though.

See also "anaemia of chronic disease" -- people with chronic infections or inflammation often end up suffering from what is effectively iron-deficiency anaemia, because their bodies sequester iron to keep it away from pathogens.

My approach: ln(19683) ~ ln(20000) = ln(20) + 3 ln(10) ~ 3 + 3*2.3 = 9.9. 3.3 = 1.0 + 2.3 ~ ln(e) + ln(10). My mental landmarks are ln(2), ln(e), and ln(10), roughly 0.7, 1.0, and 2.3 respectively.

early model Sun workstation (pizza box years) rated to survive EMP with shielded casing, monitor, etc. Obviously, while it might survive some EMP, there's a limit to the efficacy of the shielding. Anything your Sun workstation wou

Yes, but the scenario where you're relying on a mechanical clock because it survived an EMP attack is the scenario where you're getting attacked with nuclear weapons . Which... I dunno, the idea of rowing to safety seems a bit i

Is there any point knowing exactly where you are if the ship is dead in the water because all the electronics are fried?

There's an antiviral drug which is used to treat COVID. It works by causing a specific type of error in viral DNA copying. These errors usually result in the virus dying, but in some cases it could theoretically survive and still spr

Rather to my surprise, I have never received such a request. I don't know if this is because Tarsnap users aren't of interest to the relevant agencies, because they know they wouldn't get anything useful, or because I'm

If stocks go to zero, it's generally easy to get your hands on them, since people holding those shares will want to realize capital losses for tax purposes. Even if the stock is delisted from exchanges, brokerages routinely "buy&

I don't know what YC employees are called, but I really hope they're "Combinations".

This was Startup News once. Then it got renamed because pg wanted the name to reflect a wider range of interesting topics and not just startups. It was also briefly Innocuous News.

I get regular emails from Tarsnap users thanking me for making it possible for them to recover data which they lost. The work itself isn't all that satisfying, but knowing that it's having a positive impact is very satisfying. In

Interesting that the judge wrote "non-family" and then amended it to "non-parental". Makes me wonder if one or both of the additional sureties (the names of which are sealed) are siblings.

Regardless, the stethoscope has (for better or worse) already been replaced for a while, at least for in-hospital care at larger US/Canadian community/academic settings, by chest x-ray and/or the increasing straight jump to

People who get vaccinated are also necessarily not people who are excluded from vaccination for medical reasons (e.g. people with weakened immune systems can't get live virus vaccines).

Isn't the Federal government exempt from taxes imposed by the States anyway?

I have the same experience with my Kona EV. Official range 415 km, but in the summer it's actually ~450 km. (Not that I ever run 100%-0% of course, but I get 90 km going from 80% down to 60%.)

Canada doesn't have the best aircraft pilots, but we definitely have the world's best glider pilots.

I don't think it's just the drivers -- my understanding is that FedEx Ground is outsourced on a city by city basis.

I haven't been impressed by Amazon drivers, but I haven't been impressed by any other delivery drivers either. My house has a new garage door thanks to Purolator (a package delivery subsidiary of Canada Post).

My favourite is "prove that the square root of 4 is irrational". It produces a "proof"... and if further interrogated admits that 2 squared is 4, but insists that the square root of 4 is nonetheless an irrational number

US taxation applies to dual citizens who don't hold US passports though. Heck, it applies to people who don't even realize that they are US citizens -- a number of Canadians have been hit by large bills from the IRS after discov

I see it the other way: Corporations can invest in anything, so if any asset class outperformed equities we would soon see corporations listed on the stock market which simply held those assets. (This happened with BTC, with limited succes

All the option parsing is done in functions called by the macros. The "getopt string" isn't needed since the GETOPT_OPT() and GETOPT_OPTARG() "case statements" convey the same information (the set of valid options)

Another option with similar levels of macro (ab)use is my "magic getopt" which lets you write code like this: const char * ch; while ((ch = GETOPT(argc, argv)) != NULL) { GETOPT_SWITCH(ch) {

Isn't the answer to "what do you do if a storm hits the bay area" simply "go back to sleep because all our servers are hosted in us-east-1"?
