Correct. Surgical masks help. N95 masks help exactly as much as surgical masks. Poorly worn N95 masks are equivalent to surgical masks, therefore poorly worn N95 masks help as much as properly worn N95 masks.

The US is going to be full of people wearing N95 masks incorrectly. This paper says that's ok they are still protecting themselves against viruses, just in a needlessly expensive and uncomfortable way that could be accomplished as well with a surgical mask.
Internet Tips
I picked up my first ever games console this year, and got upsold a few months of Microsoft's Game Pass with it, and it's gold: Netflix for gaming, across two of the major platforms (Windows and Xbox). Much like Netflix there's more stuff there than I know what to do with; from my perspective, it makes it harder to see what the value of Stadia is, exactly. Especially when an Xbox One S is about the price of the Stadia starter package these days, and I can stream games from Windows or an Xbox as well.
Google is an engineer-driven company. They're great at building solutions, but terrible at packaging them up as products. Making them desirable, and easy to understand, and just having any kind of unifying vision at all. Nobody who understands this fact is the least bit shocked about how Stadia is turning out.
My Local Cosco was packed this weekend (US-midwest). I've been there on other weekends and it's not that bad. Many disinfectant-related products were sold out.

Makes no sense why ML isn't used, with a quick peep at a potential positive by a human before they rip your luggage open with a buck knife.
Discussions are good for critic and improvements. But to get up and running i.e. setting up your environment, building things, understanding existing design, running from source, finding roadmaps, getting list of open issues and setting up for debugging should not require talking to anyone.
There are a couple of projects focusing on continuing development of python 2, and possibly backporting python 3 feature where it makes sense. https://github.com/naftaliharris/tauthon seems to be the one with the most support.

The other problem is that it's not only your python version that won't see official upgrades, but most of the libraries you use won't either. But I guess if you're OK with Python 2 you're probably also OK with out of date versions of django and numpy or whatever else you use.

But basically, anybody who hasn't at least started their python 3 port by now have probably already weighed the pros and cons and decided that they're never going to do it, and yelling at them isn't doing anybody any good
I agree with this skepticism. There is no strict link between high risk and high return.

Microsoft was not high risk (as noted by Gates), and it provided a return that is so large it might as well be off the scale for the purposes of this discussion (their market cap was recently up around $1.3 trillion; Gates will have pulled over a hundred billion dollars out of his ownership in the company over ~45-50 years).

- Microsoft had very high margins from the beginning. They operated thin and were very cash rich within the first few years. Just a few years in, Gates had Microsoft hoarding multiple $500,000 government bonds (~$1.5m in today's money) from accumulated profit, because they were already very profitable (there is a story about the secretary misplacing one of these bonds).

- Microsoft was founded for relatively little money - $10,000 - and with zero outside VC money. Gates & Allen came up with that capital from working various industry jobs in the prior years.

- They nailed down a serious customer (MITS) and then founded a company, rather than the other way around (found a company and then try to find business for it).

- Sales went from $16,000 in 1976 (first months of operation), to $8m for 1980, and $17m in 1981 with 40 employees ($17m is $50m inflation adjusted). Three years in they were gushing cash.

As far as I can tell, there are no studies showing a higher ACE2 causes more severe disease. Sure, it could, but the pathophysiological models and animal data suggest that it is the loss of ACE2 that may drive disease severity.

There is a contradictory preprint (that hasn’t passed peer review) on ACE2 mRNA expression in smokers’ lungs being higher than non-smokers; but there is data saying the opposite happens in animal models of mice exposed to smoke:

https://pubmed.ncbi.nlm.nih.gov/20178811-losartan-attenuates...

There is also an inaccurate preprint on ethnic groups and ACE2 expression with a low n count which also didn’t pass peer review.

ACE2 loss is probably bad, having more ACE2 probably doesn’t drive disease severity:

Instagram is full of this bullshit. I routinely get dog food ads that advertise that their dog food has "vegetables" in it. Why the fuck would a carnivore need "vegetables"?
> This is a very ignorant response so I assume all your answers are the same.

If that is ignorant then I guess most companies founded in the 20th century (without analytics, stalking and targeted advertising) must not be real then? In fact I'd argue most of the money that funds the cancer that is modern advertising, marketing, etc was made before such things were actually invented.

> I think you meant "advertising"

I kind of agree, and this is why I clarified my definition of marketing. For me, marketing is about putting your product in the best light possible on your website (or physical space if you're into retail), so that people who stumble upon your product (randomly or by searching for it) will be encouraged to buy it.

The modern definition of marketing however seems to be stalking (aka analytics), spam (newsletters, push notifications), creepy targeted advertising (often relying on the previous items) and so on, essentially forcing your product onto people who haven't asked anything. I consider this modern marketing to be cancer.

> The free "no subscription needed, just buy the game" tier of Stadia is the thing that should in principle be distinguishing them from the competition, and is actually kind of compelling from a consumer perspective

Isn't that how every other game store works as well? Unreal's, Steam, Microsofts and others all work with that same idea. They also have additional subscription services, but by default it's just "no subscription needed, just buy the game"

I think that this is a lock around dlopen(). dlopen changes the list of mapped objects (and therefore, the mapping from instruction pointer to unwind information).
The problem is trading server latency for input latency, which is much worse. Most console gamers probably wouldn't mind it as much as they're used to TV latency, but the higher you go in competitive games, input/display latency becomes much more important. And if you count PC gamers it's much more of an uphill battle as display latency there is miniscule compared to consoles & televisions.

> Compared to the traditional dedicated server scenario, cloud multiplayer gaming could nearly halve the player to player latency.

There's still the network latency from your streaming edge to the game server, and yours to the streaming edge. You can just use the same optimized routing to reach the shared game server.

Improving routing or using multi-pathing solutions can achieve a similar result. Things like Haste, which offer optimized routes to supported games and shoot your packets across 4+ of them at once for redundancy, can cut your lag tremendously. Haste is a particularly good example because, at least from my packet capture, it looks like they're partnering with ISPs and putting their edge nodes in ISP datacenters.

I don't really approve of that. I know it goes on, but I'm not giving my seal of approval to that.

It's just a pet peeve of mine that dressing well is often mocked as frivolous. It often has a gendered component to it, like women are silly creatures.

I knew a professional couple that both worked at the same place in different departments. She talked about going shopping and both of them spending hundreds of dollars on office clothes over the weekend.

The following Monday, she got teased at work for wearing a new outfit. No one said one word to her husband about his new office attire, though he had spent at least as much as her.

My annoyance about how socially acceptable it is to act like nice clothes are merely stupid status symbols is in no way intended to justify deceptive marketing, especially for medical stuff.
Wait, how is adding more servers into the mix going to reduce latency?

As a counter point to GeForce now and cloud gaming in general. I splurged on a shield tv 2 (maybe 3?) years ago and it was a configuration nightmare, especially to play your own games with. Getting controllers to do the right thing was horrendous, especially when you have young kids waiting for you to finish setting it up.

Definitely planning to be a late (real late) adopter of this tech in the future.

While the OS will not move, Microsoft wants you to move to Azure AD and Intune for Management instead of OnPrem AD and Group Policy

They want that monthly per device revenue, and I would not be shocked to see EA CAL and Core CAL prices increased very soon to be more than the Equivalent Cloud Product.

I think past 2019 Versions of Server Products it is about to become VERY VERY expensive for companies to Continue with OnPrem Microsoft products.

better start looking at Directory389 and and FreeIPA..

Edit:

Since I am rated limited (posting too many controversial things)

I will edit my post to say MS has been signalling well since Ballmer left that Onprem is deprecated and will be a second class citizen in their Line Up

This is just further moving down the path of eliminating all OnPrem for Azure, 5-10 years I would say MAX before they end all support for the Server Side of OnPrem, or it will become Azure Stack and the only way to use Windows Services is with a Hybrid Azure, so your OnPrem AD will be a Cached version of AzureAD

Indeed I am working primarily on Rust now, though I used to write Node 2 years ago and this is one of pitfalls where I would like to rely on compiler. It was just one issue which could been easily detected. Some debugging time was spent aligning SQL query parameters and mapping selected fields to the output type - the problem is that when there is some misalignment node does not raise exception, rather just passing undefined value. That's what takes time, to realize that there is a problem and then find the issue.
Agreed that in general expert in node probably won't hit such issues, though how many experts do we have. Type safety checks, including runtime checks, are actually making technology more adoptable. It does not seem that typescript can do that well though.
Exactly right. "Compared to what?",

I had a really cool internship fifty years ago (when I was sixteen.)

The group was doing pioneering electrocardiogram recognition (now the commomplace monitor beep beep beep). We had a bunch of scary-smart M.D.-Ph.D doctors figuring things out.

And I got to try to make sense of all their code and make it work together. I remember putting copies of Dijkstra's Damation article all over the place so those guys would read it.

They did read it. They liked it. They talked about it.

And then they started to be able to debug their stuff and get it working together.

If I'm reading this correctly, Joe uses docker running on the same host as your regular production db, and provisions a snapshot, and a new docker image to mount it. So yes, your production DB data is 'safe' but if your query uses lots of CPU, or lots of Disk IO, then its still going to fight the other images on the system for resources. IE, a Full Table scan of a 2TB table is going to affect the other docker systems running on this same server.

Yeah, I have a Prius Prime with similar range. It can do basically one outing and back in my city before it needs charge, and at 6 hours to charge on a 110 that means the gas kicks in many days.

Now, since this is a smaller vehicle with a smaller battery, it might able to charge faster on 110, but likely you'd want a 220 charger.

Really, it feels like all EVs will need a 220 line to be practical. Small-battery and PHEVs need frequent top-ups and you don't want those to take hours, and full EVs just take forever to charge on 110.
