A bit of a bad analogy as, in water, the sodium and chloride are not bound together; rather, the ions are separately distributed throughout and wouldn't have the same density that they would have in a dry, crystal, ionically bound form.
The mods probably added the date to the title later to make it clear. It was discussed in 2015 https://news.ycombinator.com/item?id=9425587 (55 points | April 23, 2015 | 11 comments)
Stories about historical artifacts are popular here and it's not unusual that they are reposted a few years later by someone that missed the original discussion.
This is news to me, and I like classic ADVENT type games. I've bookmarked it for future investigation, and maybe tackle the broken LOAD/SAVE in the pure DOS port.
I use Control as well, and it was an adaptation to prevent typing spaces or letters into the password field that I would have to delete before typing in my password. Perhaps you had a similar experience.
Certain viruses maintained their lethality as time went on. Smallpox was very lethal throughout time. Influenza lethality ebbs throughout history. I don't think we can or should depend on less-lethal, common-cold-like symptoms from Covid-19 at any point.
SARS-CoV-2 does cause common cold like symptoms in the vast majority of cases, just like other coronaviruses. In particular it's quite similar to HCoV-OC43. The only reason those other endemic coronaviruses don't kill many people is that most of us get infected as children and build up some immunity.
There actually is. The evolutionary selection pressure on most coronaviruses exists throughout its infectious stage. So in order to be more infectious for longer the coronavirus would become less symptomatic and so less serious.
But with C19 we are aggressively isolating people with symptoms. This focuses evolutionary selection pressure on the initial infectious stage. In order to be more infectious the virus increases viral load and shedding, causing more serious symptoms; which would be an evolutionary disadvantage, except isolation renders this disadvantage moot.
Also natural immunity general focuses on the nucleus of the virus, vaccine immunity is to the spike. So this forces mutations in different proteins, which has different results.
It's an interesting argument; however I am a little dissuaded by the fact that half of the support for the claims of similar syntax between Norwegian and English (split infinitives and placing a preposition at the end of a sentence) are generally considered poor grammar in English.
They're considered "poor grammar" for historical reasons (mainly because they're impossible in Latin), not because they are not understood (compare to "I the dog kick" which is ungrammatical in a much more rigorous sense). From a linguistic standpoint what's interesting is what is understood and what isn't, not what is the most proper.
Those protests were popularized by grammarians who learned grammar thru a Latin lens, so, to them, being used to the Latin grammar, this construct in English looked incorrect. From a Germanic language context, though, it's perfectly normal.
