This is really cool tech, amazing that somebody's managed to get dynamic valve action working reliably. What I'm wondering, though, it what the benefit is of using it on a hybrid car.

It sounds like they did connect the engine mechanically to the drivetrain, with the electric motors mostly assisting. But why not have it just directly drive a generator, with some decent sized batteries? An engine that only runs at full power at a single RPM to charge batteries doesn't benefit much from elaborate valve technology.
> "Plan for at least a week, if not two ahead."

30-60 days would be a safer bet, plus a little extra to help out friends and neighbors who failed to prepare. That isn't to say that the current panic buying is justified but that, in general, that's how long it seems to take before relief efforts fully come online in the event of a disaster and should therefore be the normal standard for preparedness.

> "Someone correct me if I am wrong but cargo transports haven't stopped (ships, planes, trucks, trains). These things will keep coming in and stocking up the necessary stores.

This hasn't occurred domestically and it's likely that stores will be continued to be stocked for the moment. In the intermediate term, reportedly freight shipping from China seems to have slowed drastically (e.g. https://www.eastbaytimes.com/2020/03/13/coronavirus-oakland-... and
https://www.seattletimes.com/business/international-trade/se... Disable Javascript to get around the paywall.) and this might (emphasis on might) eventually have cascading effects on even products from the domestic manufacturing chain depending on how long production and shipping from China takes to be restored. Even if a product's primary components are domestically produced (toilet paper seemingly being the canonical example these days), the machinery, packaging, etc. may depend on supplies or replacement parts from overseas.
Yes.

There's between 50k and 500k people in the US with covid19. At this stage it's fairly immaterial to give people tests that take 2 days to run.

If you have a temperature or a new cough, just assume you have it, and self isolate, ideally asking people to report they are self isolating too.

They should be doing mass temperature scans to find people with high temperatures at large events, subway stations, shopping malls, etc. Far easier to test en-mass, and gives an indication.

I have a couple of 30+ year old backpacks. One thing I like about them is that they don't have thousands of zippers and compartments, so they're quite lightweight despite being made of relatively basic materials.

One of these backpacks has been my companion on every plane trip I've ever taken. Unfortunately, I learned the hard way last summer, that it's no longer waterproof at all.

It's more than wet markets, although those are obviously dangerous. It's the continued expansion of human population into rainforests and other wildlife areas:

> Yes. EcoHealth Alliance, an NGO, and others, looked at all reported outbreaks since 1940. They came to a fairly solid conclusion that we’re looking at an elevation of spillover events two to three times more than what we saw 40 years earlier. That continues to increase, driven by the huge increase in the human population and our expansion into wildlife areas. The single biggest predictor of spillover events is land-use change—more land going to agriculture and more specifically to livestock production.

This is not going to be fixed easily. Everything from the deforestation of the Brazilian rainforest to Chinese population growth is driving it.

Given the cost of Lithium Ion batteries, especially the human costs of mining Cobalt, I would argue that hybrids are the better technology today.

You reduce the Lithium-Ion battery size, and then increase the range of cars. Li-Ion is also extremely heavy, reducing range, increasing wear-and-tear on the road.

In overall costs, hybrids make sense today. We need another magnitude of improvements before Li-Ion batteries can completely replace ICE.

But we are absolutely at the point where Li-Ion can augment cars in hybrid form. Maybe in a few years, a Cobalt-free battery would be mass produced (or other chemistry that doesn't need to be sourced from war-torn nations).

And in the meantime, increasing ICE efficiency by 30% (on TOP of the Hybrid savings) is only a good thing.
Epidemics: The End of Containment Measures?
For basic goods like toilet paper, production hasn't fallen, and consumption hasn't risen. Distribution is still adequate for the amount of production and distribution, so it's not directly the problem, either.

The problem is buffering. Normally, buffering happens within the supply chain -- the back rooms of stores, loaded in trucks, warehouses, distribution centers, and the factories themselves. Now, we are telling everyone "buffer at home so you don't need to go out so much". But the problem is, buffering is much less efficient at the end of the chain, so you need to buffer a lot more. That's causing a short-term strain on production and distribution.

Blaming selfishness or gouging probably doesn't do much to help this problem. My guess is that the biggest problem is the discrepancy between how much stuff would be needed to buffer within the supply chain versus how much stuff is needed to buffer at the end of the supply chain (i.e. at home).

Worse, because it's a temporary buffering problem and there's no real increase in consumption, there's little incentive for production to increase now to alleviate it. Any increased production/distribution now just means less demand later when people start to work through their caches at home (and stop buying for a while).

So the only way to alleviate this is to allow the prices (that manufacturers charge) to rise, which will give manufacturers a cushion against the inevitable slump in the future. That's not very popular and not worth the brand damage, so it won't happen.

The good news is that I don't think this will last more than another few weeks. Gougers will stop buying at some point because they don't want to get stuck with a huge supply of toilet paper and no channels to sell it. And the home caches will fill up.

EDIT: this analysis has nothing to do with things like facemasks, where consumption has dramatically risen.

Just because Glitch joined CWA instead of forming their own union does not erase the fact that they are a tech company that became a union shop. And 2 is definitely more than 0, that's just simple arithmetic.

Finally, I never said "high-profile" had to mean FAANG. These two are high-profile cases that gets public attention- not necessarily because the media is manufacturing a narrative, but because Kickstarter, for its small size, is a household name. And Glitch is the successor of Fog Creek Software- this company, as well as Anil Dash and Joel Spolsky, are certainly high-profile names in the tech startup scene. We're not discussing some unknown boutique consultancy.
> This is not a case of toilet paper suddenly costing more to produce

Production and logistics have gotten more expensive. That has happened economy-wide, and will only get worse as the pandemic exponentiates. They’ve also become less reliable, which is why we have hoarding.

The purpose of price spikes is to incentivise production, to create slack in the system. (It also reduces the quantity demanded. Toilet paper at a 100% premium doesn’t do much to someone purchasing a normal amount. But it is material at hoarding volumes.)

One could say “we don’t want more price discrimination.” But that is a choice to prefer shortages over price increases. (Which is fair.) If I have a warehouse of toilet paper, I am incentivised to ship it to Texas or New York over California. (Counterpoint: low income consumers there are going to face pressure to use alternatives.)

Bottom line: these are not costless policies. (That doesn’t make them bad per se.)
The Last Hurrah Before the Server Recession
The primary transmission route in inhalation in close proximity to an infected person. Yes, it can persist on surfaces, but this hand-washing meme is mostly a result of (1) it costs nothing and may help, so we should try and (2) masks are supply limited and the healthcare industry doesn't have enough. In reality, if we had an abundance of masks, masks would be more important than hand washing. As it stands, we reserve them for HC workers and infected persons. The point being, subways are worse.

Road wear is IIRC to the 4th power of weight.

That is to say, a 4500 lb Tesla Model S has 5x the road-wear of a 3000lb Toyota Camry.

If all Tesla Model S drivers were willing to pay 500% the road-taxes to make up for their 5x damages that their cars do to our roads, I think I'll be cool with them using their road-destroying heavy batteries.

And the F150 drivers too, while we're at it.

Xe is conflating compilers and calling conventions a bit. The way that structure types are returned varies by calling convention, as indeed do a lot of other things. Mismatched calling conventions leads to problems.

But structure type return values are well specified for most calling conventions, and quite a number of compilers support explicitly specifying the calling convention for mixed-language or mixed-compiler situations.

To my recollection (corrections welcome), the covid19 virus has been reported to live on hard surfaces for 8 weeks, have an incubation period of up to 4 weeks, and live 5 weeks in vitro after confirmed infection ... if you're sanitising several times a day then that's a need for quite a long stretch of sanitiser.

You're right, but for wrong reasons. Internal combustion engines will go away, because electric vehicles' cost curve will destroy them.

IIRC, batteries get 13% cheaper per year, and that means price halves every 5 years or so. Right now 1 kWh of batteries (including BMS) costs about $100. So in 2025 one kWh of batteries will probably cost only $50.

Electric vehicles purchase price will simply be cheaper unless ICE vehicles get subsidies. At that point, for economical consideration you'll need to have pretty compelling reasons to buy an ICE vehicle.

Ultimately even gas station network will be decimated and gradually fade away.

They thought they could corner the market and know nothing about the ability of the US logistics system to resupply in face of a small increase in demand likely caused by speculators rather than a huge spike in demand.

Good points but "I either want a quick notification about some critical error with everything inside, or I want nothing", so this is hoping a) you will never need as much information as you can about a hard issue you are trying to debug/RC and b) you will never have to go through any audit/retro touching this path.

I operate a couple of Elixir apps and so far a simple Makefile with a couple of shell scripts has been enough. This simplicity is due to the fact that the only external dependency is a database server, everything else (language runtime, web server, caching, job scheduling, etc.) is baked in the Elixir release. One unfortunate annoyance though is that Elixir releases are not portable and can't be cross-compiled (e.g. building on latest Ubuntu and deploying to Debian stable won't work) so we have to build them in a container matching the target OS version. So to be really honest I should mention that Docker is also part of our deployment stack, although we don't run it on production hosts.
