Ask HN: Who pays the extra cost of WFH?
So in the current wave of the virus, many of us are being told to WFH on a permanent basis.

For my part I would normally have WFH once a week, but now that I have to do it full time, I'm wondering should the company cover the cost of that?

After all there is going to be a lot more electricity usage etc. Just curious what our full time WFHers do?

Of course - because it's a silly title. Give an article a silly title, expect silly comments.
Herd immunity is a term describing a steady-state distribution and one avenue (the typical one) of getting there is vaccines. Typically when 80% of the population\* is immune for one reason or the other a population is said to have herd immunity. The idea is statistical safety for susceptible individuals (yes, typically those that cannot be vaccinated for $reasons) thanks to being significantly outnumbered by those immune/resistant to infection - or a buffer population acting as a firewall, if you will.

I haven’t seen the term used for small pox in the Modern Era, but I believe it would be fair to say even though the small pox vaccine hadn’t been invented (and wouldn’t be until 1796), there were definitely periods of herd immunity in major European cities/ports of the time as it absolutely destroyed the previously unexposed Native American population.

But when dealing with “learned immunity” due to previous exposure as compared to natural/genetic immunity to the same diseases and the antibodies are not passed down from mother to child, what you’re going to see is a resurgence in cases as each new generation loses that immunity. In the present case, the unvaccinated herd immunity would be something to keep spread in check until a vaccinated herd immunity can take its place (assuming the vaccine isn’t developed before 80% of the remaining population has been exposed to and has recovered from this particular variant of the coronavirus).

\* at least that’s the number we were taught in my livestock/farm animals veterinary medicine class a decade ago.
> Your comment about not being older than 60 to get tested made me so angry and shows how fucked the US is

I live in the (presumed) social democratic paradise of Sweden where the "government" has just decided to stop testing anyone who is not already in a hospital and belongs to a risk group, i.e. anyone under ~65 years of age without any co-morbidities [1 - Swedish]. The "state epidemiologist" Anders Tegnell has other wisdom to spread to the world like the fact that a call for as many companies to have as many employees as possible working from home is "problematic" because it ends up exposing some people to more risk of infection than others and thus offset the principle of "fairness" in society [2 - Swedish]. In other words, if we can not lower the risk of exposure for everyone we should not lower the risk for anyone. He is also against school closures because children can not get infected - oh, they can? OK, because children don't get very ill - but they'll still spread the infection to those who can get very ill? OK, because some children don't have it all that nice at home so it would not be fair to them to close the schools. Again, if we can not make it better for everyone it is preferable to not do anything at all.

Sweden is now coming under heavy criticism from other countries, China being one of them [3 - Swedish] when they state "Sweden has capitulated in front of the virus and stands to become a danger to other countries". This is probably part of an ongoing spat between Sweden and China where Sweden earlier criticised China's actions against a Chinese-Swedish citizen but there is no denying that the Swedish "government" has shown a lack of foresight and proactive strategies. There is a dearth of supplies, Sweden has the lowest number of hospital beds per capita in the OECD which is odd for the country with the highest taxes in the world, the health care system can not cope with the normal case load let alone with an influx of Corona-related patients.

I started my career on a project that was 90% C# and 10% VB.Net. Most of the work in VB.Net was junk code that I had to refactor; ultimately, it didn't make any sense to use VB.net for that code.

I could never really understand why there was VB.Net. It had some language features that C# didn't have, but they were features I'd never use in an industrial strength program.

Italy also wasn't testing. Their signal was hospitals overflowing with dying patients. So it's unlikely that SK is missing significant numbers of cases. If they were their hospitals would be overflowing.
Oof. I hate powershell studio. It weirdly splits up the files and none of them are .ps1 and they obliterate all good standards and practices forcing you to leave arbitrary code in the project so that theres no way to know what pieces fit with what.

Fermi-1 in Detroit and EBR-1 in Idaho were the only fast breeder reactors that had meltdowns that come to my mind. They didn't go boom at all. Though we did get a great Gil Scott-Heron song out of the former.

As a pro-nuclear person, this is my favorite anti-nuclear song. The lyrics are pretty off though.

The Russian nuclear ice breakers like the one that took the Olympic torch to the north pole on the relay a few years ago use light-water reactors, not fast breeders.

A water-cooled reactor in the water isn't all that dangerous.

You're interpreting things through the prism of your pre-existing ideology. Someone else could see current world events as evidence of the exact opposite of everything you say here. Indeed one headline I saw lately was something like "the nation state is back"!

For instance the fact that different countries are trying different tactics let's us compare between them to see what works best. Without nations we'd presumably have the same response everywhere, so we couldn't look to e.g. South Korea to learn anything. Singapore's previous experience in combating SARS wouldn't have gone anywhere because it wouldn't have reflected global priorities.

As for your last paragraph, that's just bog standard Marxist catastrophism isn't it? He was claiming capitalism's inherent contradictions would cause global collapse in the mid 1800's but he was wrong. It's been a standard refrain for centuries but where did this outbreak start? A communist country, that oppressed the doctor who tried to raise the alarm. Not great evidence for your case.

> We can already return structs

AFAIK, no? You can return a pointer to a struct, and you can pass whole structs as arguments, but not, IIRC, return them from functions.

EDIT: Apparently you can, sort of, but not portably; how exactly it is defined to work depends on the compiler, and each compiler might define it differently. This means that if you’re using a library which returns a struct and your program use a different C compiler than the library used when it was compiled, your program will not work. I.e. there is no one defined stable ABI for functions returning structs.

Therefore I think it’s reasonable to regard it as impossible in practice.
> I think a more traditional finance person will have trouble understanding it all as in some cases, there are no analogies to the traditional finance system (e.g. flashloans).

All "cryptocurrencies" are, in effect, complex securities that are derivatives of greater market factors. The crisis of 2007 showed the risk of using complex investment vehicles that were poorly understood by investors -- and the CDOs that were sold in the mid 00s were far more transparent and predictable than cryptocurrency. Given that crypto will always be one asset class among many, if the traditional finance system (which already operates outside any single fiat currency) can't understand it, they won't use it for anything more than speculation.

Using crypto as an investment vehicle requires a reasonably accurate assessment of risk. In the case of fiat currencies, central banks manage that risk so that investors can rely on the liquidity of the overall system without wiping out deposits. DeFi has no such mechanism, and no central bank to absorb a big hit temporarily in the case of a black swan event.

I still feel that cryptocurrency is just the 21st century version of penny stocks and junk bonds. Fiat currency works because its power as currency is secured by a government able to mobilize military and industrial power to solve market problems. The most heavily traded currencies (RMB, USD, EUR) are those backed by large industrial and military powers because those countries have the scale and political power to manage market risk. Centralized governance is a feature, not a bug.
In the comment I replied to where you suggested a disease center could release a new bioweapon.

A disease center would study known diseases. A disease center could only release a new bioweapon if it was secretly a bioweapons lab — there’s your conspiracy theory. Which you’re putting forward on the internet.
This is cool because it can help quickly determine structures if the virus mutates. However, the obsession with structural biology isn’t necessarily optimal, because we’re talking about shapes of things (analog, constantly changing) instead of discrete states of molecular circuits. Check out the book “wetware: a computer in every living cell” —- cells figured out logic long before we did. Treatments which operate from a structural paradigm, like small molecules, antibodies, and vaccines, are analog. Treatments which operate from a sequence / switching / circuit paradigm are digital.

The digital solution is stronger: delete Coronavirus RNA. This isn’t dependent on shape of some molecule and how some other molecule docks with that inside a molecular blender. Genome engineering targets sequences directly, works with novel viruses right away, tolerates mutations with wobble base pairs, works in immunocomprimised patients, has potentially zero side effects, etc etc

I applaud these efforts but implore you to consider: why throw a fancy molecular wrench into the virus machine when you can instead set the “virus switch” to “off?”

If anyone’s gonna grok the benefit of digital over analog, it ought to be the Hacker News community. The hardest part is delivery, we need to affordably mass produce nano particles with the CRISPR DNA inside. That’s the number one thing holding back biotech from curing many diseases including this one: AAV is the standard vector but it only works once before you’re immune to the gene therapy.

What are some easy-to-implement tools for newly remote teams?
In light of the coronavirus, my team of mechanical engineers is now working from home. Can anyone recommend any tools that are easy to get started using that might be helpful for us?
That is just not true. There were a few number of cases, where a second test was positive after initial curing. This is being investigated and can be attributed to issues with the test, false positive diagnosis in the first place or various individual reasons. There is no evidence for a fundamental issue with adapted immunity to Sars-CoV-2.
A few more recent innovations in packs...

Aarn "bodypacks" use front bags to counterbalance the load on the back: https://www.aarnpacks.com/

NeoTrekk (formerly LuxuryLite) also offers a "front pack" for counterbalance that can be used with their pack. However, that is just one of the pack's many innovations, which include modular waterproof storage, quick-detach hip belt, camp chair conversion, attachable wheels, and more: http://www.neotrekk.com/index.html#stackpack

The McHale Bypass Harness on McHale packs completely solves the inherent adjustment problems of the traditional load-lifter design used on most trekking packs. This innovation is not recent; its US patent has expired. Despite this, I do not know of any companies that have adopted it: http://www.mchalepacks.com/sarc/04.htm

In some cases it does, in some it does not. And yes, the western world taking their flu shot does mean that those who can't afford it might have a problem or a worse problem compared to what would otherwise be. ( Also why many advocate you should only take it if you need it. )
The problem with local, less aggressive measures is that people act in their self interest to bypass them for convenience or safety, and they make the problem worse. Recent examples:

- Lockdown in northern Italy: People ran to the south taking the virus with them.
- Schools closing, folks asked to work from home in Madrid: Families drive to the coast where bars and restaurants are full.

I agree that in a place where compliance with social distance measures is high (I'm thinking South Korea, Japan), that would be enough. But that doesn't work everywhere.

Corona viruses also have an error correction enzyme in their rna transcription so their rate of mutation is much lower than most viruses, it’s likely that both herd immunity and vaccination would be effective as a consequence.

> "there already seems to have been cases with this one where a person got it twice"

Just so people know: this has not been confirmed and has been an unsubstantiated rumor for a while. It is pretty unlikely this will happen considering what we know about how things like this function on a physiological level. It is much more likely due to the changes is testing (mostly where on the body samples were taken), confusion about symptoms or false negatives.
Not FAANG but for small to medium "cloud native" businesses I like to use this approach with minimal dependencies:

Managed Kubernetes cluster such as GKE for each environment, setup in cloud provider UI since this is not done often. If you automate it with terraform chances are next time you run it, the cloud provider has subtly changed some options and your automation is out-of-date.

Cluster services repository with Helm charts for ingress controller, centralized logging and monitoring, etc. Use a values-${env}.yaml for environment differences. Deploy with CI service such as Jenkins.

Configuration repository for each application with Helm Chart. If it's an app with one service or all services in a single repo this can go in the same repo. If it's an app with services across multiple repos, create a new repo. Use a values-${env}.yaml for environment differences. Deploy with CI service such as Jenkins.

Store secrets in cloud secrets manager and interpolate to Kubernetes secrets at deploy time.

Cloud provider keeps the cluster and VMs up-to-date, CI pipelines do the builds and deployments. No terraform/ansible/other required. Again, this only works for "cloud native" models.

How can we be immune to a brand new disease?
Epidemiological modeling: A basic SIR model for the epidemic
I'm not sure how sound is UK's strategy.

Current advice is to self-isolate for 7 days if persistent cough suddenly appears and/OR a temperature of 37.5°C (that is not high temperature).

That sound like good advice, but they are not going to test those cases unless it ends in hospital. And they don't want you to call to the NHS help line or go to the doctor (again, not bad advice but I see some people getting anxious about this; IMHO at least the help line should be available because most people aren't doctors).

Considering that it could be a mild case of the disease or any other common seasonal disease (I have two toddlers at home: they get ill), how can we tell we had passed the disease and we have some immunity?

Besides, if testing and tracing stops, it means there won't be information about the progression of the epidemic in the UK; which sounds to me like a bad idea (but I'm not an expert).

Considering how the Conservative government has been underfunding the public health system for 10 yeas, I understand how their approach can be seen by some as untrustworthy.

EDIT: I see this may be off-topic re: herd immunity, sorry about that.

> When donating money or compute time, I want my donation to be used efficiently and not be wasted by high overheads.

Fair point. I think this is something you should bring up with the authors of Folding@Home. I do not work on that project.

My personal view on this is that there is always a cost/benefit balance that one has to strike which is often tricky especially given the considerably constrained resources as it is typically the case in academic computational/simulation tool development.

It is however, as you point out, a great responsibility of the researchers and developers of codes to make sure that choices made and action taken (or not) do not lead to disproportionate waste of resources donated by volunteers or awarded through a grant by research funding agencies.

I do not know the detailed reasons why F@H chose to not update CPU "core" since FahCore_a7 (AFAIK based one GROMACS code from 2014), but it is likely related to the aforementioned cost/benefit analysis done in their team.
One of the motivations could have been (just hypothesizing) that the software engineering efforts estimated to be required to update FahCore for CPUs (which generate a very small fraction of the "points") would have taken away resources from the GPU FahCore.

There's also a huge selection bias the other way, in that people with mild symptoms may not even know they have been infected with covid-19.
I wish there's a way for people to self-report and self-track their progress if they have the virus/disease. Having real numbers, not the number determined by Xi or Trump or [insert your hated government baffoon here], would be useful.

Sadly something like that would probably have a lot of trolls, and hypochondriacs.
Yes, just like Bos taurus is the official name for a cow. Normal people call it "cow".

The common name for the virus is Wuhan virus.

There is an effort by the Chinese government to pressure people, especially news media, into not using the common name. It's sad to see Hacker News caving in to this. Articles with "Wuhan" in the name are not showing up; they seem to be blocked.

No, it isn't offensive. We frequently name diseases after locations. Ebola is an example. MERS is an example. Spanish Flu is an example.
there may be people who continue to test positive, but there have been no confirmed instances of reinfection.
Last time I tried apple cider vinegar the pH was so low it gave me a chemical burn in the back of my throat. It definitely can hurt, so be careful with that stuff.
Yeah, but won't they at least put you in line if they intend to test? Sounds like the lack of capacity is a good excuse to lower the statistics.
