https://blogs.sciencemag.org/pipeline/archives/2020/04/15/co... is a post from April of last year detailing the different types of vaccines, which does mention some of the issues mRNA vaccines have had in the past. I think there's a fuller discussion of mRNA somewhere on that blog, but the gist of it is "we've been trying this for about a decade and we might finally have all the kinks worked out."
So they'll be out of business sooner or later then and a company that follows security best practices will take over ideally.
To their credit, false positives are the designed nature of PCR.
I traveled a bit during this pandemic and in Arizona it’s like the virus didn’t exist. Nobody was wearing a mask, nobody. Even indoor. Even the waiters.

I’m back in SF now and everybody is wearing the mask. Everybody. The adults, the children, Even the vaccinated people. Yesterday the waiter asked me if we could put back our mask so she could hand us our plate.

Country of extremes. I feel like there’s no going back to normal eventhough I’m fully vaccinated.
Easy, we just nuke the mountains. No steep gradients and no more tunnels. I’m available for consulting work if anyone at CP or CN need me.
I knew when Apple released the iOS update that lets my Apple Watch unlock my phone when wearing a mask, that it would mean I would very soon not have to use it anymore. Some corollary of Murphy's Law.

Not that I'm complaining!
Unfortunately for many, rescinding the mask mandates means removing a rather convenient tool to twist the arms of their political opponents.

> Zulip has a notoriously bad db schema.

Interesting, I've never heard that rumor before.

> a single write in a 5000 member public group would result in 5000 writes to the user table.

This hasn't been true since we implemented soft deactivation in 2017. You can read about the feature in our documentation here; I think it's a pretty cool design:

https://zulip.readthedocs.io/en/latest/subsystems/sending-me...

The optimization takes advantage of the fact that public groups with 10Ks of members tend to have a lot of totally inactive users, and so if you have a good way to know that only 600 of them have logged in during the last 2 weeks, your server can run like it only has 600 users.

It is true that Zulip writes a tiny UserMessage table row with (user_id, message_id, flags) for every active recipient of a message, we need to do so in order to track the unread state for all of those recipients (as well as related details, like mobile push notifications state). We need to write to that row a second time when the user reads the message.

With modern postgres and SSDs, writing 1000 rows is really cheap, and so part this is extremely fast when sending messages with 1000 online recipients, which isn't a thing real users do constantly anyway (since that's effectively an announcement, not a chat message).

Folks who are curious can read https://chat.zulip.org/#narrow/stream/3-backend/topic/send_m..., which is related optimization work we did this week that made it into this release.

(You could have a bad experience if you use remote storage that rate-limits "IOPS", though, because AWS at least used to count each row as an IOP and would use your full quota for 20s if you marked 20K messages as read with a 1000 UOP/s plan).
The problem is they didn't say "masks work but please save them for first responders until we get more." They said "masks don't work." You can argue they may have had a good reason to lie, but you can't argue that they didn't lie.
They are starting to lose money, it's 5M$ today, who knows what it'll be tomorrow or how often it's going to happen.
Someone mentioned that these could be terrorists posing as hackers. So, why not both?

I’m wondering if in the grand scheme of things this could be one more reason to speed up development of solar/wind + distributed energy production.
Long term effects of an unproven technology? Who knows what this will do to your body in 10 or 20 years?
Yeah, I was ignoring sideways velocity. I was taking "just look up what happens when you drop a 10ton tungsten rod from outer-space" perhaps a bit too literally.

If we add in 1/2 * 10,000 kg * (7500 m/s)^2, to account for sideways LEO-equivalent momentum, I have it coming out as about 0.0906 kilotons: about 4 times more energy. Which isn't too surprising, since the hardest part about getting into orbit isn't the going up part, it's the going sideways fast enough enough part.

My whole formula is this: (((10000 * 9.8 * 1000000) + (0.5 * 10000 * (7500 * 7500))) / 3600000) / 1162200

Basically, (mgh + 1/2 mv^2) converted from joules to kilowatt hours to get it into a larger unit I can sort of relate to, and then converting that in turn to kilotons equivalent TNT in order to compare with nuclear yields.

That's assuming I didn't leave off some zeroes somewhere or apply a formula incorrectly.
The headline is a bit clickbaity.

> At least eleven accounts that originate from Greater China were suspended.

You may have heard of two of them. They weren’t pulled because they were Chinese, but because they violated the terms of their agreement (by paying for reviews).
Another form: you don’t need to outrun the lion, just the guy next to you.

This also gets taken in dark directions: you don’t even need to run faster than the guy next to you, you just need to trip him up.
Oh wow, and the offender is now living freely since 2017. Good to know.
It's not about being sure it will work. It's about giving options for decent food to people who want it, not physically forcing it into their bodies.
"For some people... Tesla is a religion."
That’s a pretty silly way to look at it. There are a lot of reasons, but the most obvious is that you just moved people around, you didn’t get any new ones. It’s zero sum in the short term, because there are many many years of latency to correct the talent pipeline on something like security.
Not really BS: If it is really less compensation then employees.can view that as the price for job flexibility. And if they don't want or need that flexibility, they can go get a (maybe) higher TCP with a multi-year lock.
I consider myself very "science minded", which is why I absolutely hate the phrase "trust the scientists." Primarily because science is all about having a healthy skepticism, and if anything it's about trusting the scientific process (even then, "trust" is a not a great word here - we "trust" the scientific process because history shows it works).

The CDC has made plenty of mistakes and mishaps during this pandemic, so "trusting" them would be foolhardy in my opinion. That said, the CDC has many brilliant people working for them, and unlike many of their critics in my opinion they are always acting in good faith.

But they still exist in the area of public health policy, which is about much more than just "science". Zeynep Tufekci, a sociologist, has had some of the best articles and analysis throughout the pandemic. She advocated public mask wearing when the CDC was telling people it wasn't necessary, and she just recently said the CDC's mask guidelines were too timid [1].

The message shouldn't be "trust the scientists". The science here is actually not that complicated that most people can't grasp it. The message should be to dig in to the science that is presented so you can make up your own mind.

There is no way to say that with certainty. SpaceX is far from the only rocket company and while yes, they have had great success, their success only makes it harder for other rocket companies to stand out and succeed. What if another company was just a a year or two behind SpaceX but got their funding shit on when SpaceX launched their rocket?

SpaceX is standing on the shoulders of giants, if SpaceX didn't exist, the science and people wouldn't just disappear.
Abandoned is perhaps too strong a term :-). Effect handlers in the language are supported by fibers, lightweight stacklets managed by the runtime. The details of the implementation can be found in the upcoming research paper in PLDI'21 conference [1]. The effect handlers in Multicore OCaml today do not provide effect safety. Programs are not statically guaranteed to handle all the effects they may perform. This is only as bad as exceptions in OCaml and every other mainstream language with exceptions.

We are working on developing an effect system, which will ensure effect safety i.e, the compiler ensures that all the effects performed are caught. You also get a nice inferred type that says what effects a particular function may perform; if it performs none, then it is a pure function! This implementation would still use the current fiber support in the runtime. Leo White, one of the developers of Multicore OCaml had given a talk on this new effect system a few years ago [2]. That's the best place today to learn about the new effect handlers.

The plan is to first add the fiber runtime support to OCaml without the syntax extensions for effect handlers, and then introduce syntax along with the effect system.

why would solar or wind have any better security, if the incentives for better security isn't really there in the first place?
Weird to see this downvoted, it’s completely accurate and pretty basic economics. Security is a cost center, product development is a revenue multiplier. Investing in the latter as much as you can get away with is the most rational way to allocate resources.
How so? The risk of a bad outcome from children under 12 catching COVID is basically nil.

Sigh, it is a paradox.

As a consumer, I want my software on-prem. But as a producer, I want to deploy as frequently as possible, so that I could iterate without friction, and I would try to avoid platforms/techs that are not hot upgradable.

As a consumer, I want no data tracking. But as a producer, I want data-driven growth, so that I could understand where I did wrong and how to improve it. And data comes from tracking.

This paradox is not just limited to the software industry: For example as a consumer, I prefer reading texts. But as a producer, I found videos are easier to monetize because of the attractive/addictive nature.

More often than not, the formers which benefit consumers are not justifiable in pure economic senses compared to the latters, thus the reality we are living in nowadays.

Texas.

That would depend on how you classify 1%.

The effective tax rate for an individual earning $400k would be around 31%.

Like I said, even approaching 40% is obscene. 50-55% is absolute thievery. I would relocate from Texas if my effective tax was even close to 40%.
Ditto. Sometimes I get some CPU spikes but overall it has been amazing.
You can have both though. In Europe and Asia you can usually choose a train with few stops or many on the same line, and you’ll see the fast train blow by the slow one as it’s stopped at a minor station.

What blows my mind is the concept of sensor fusion and how it works in the brain.

How you can infer the shape of an object by progressively touching it with your fingers even if you cannot see it. Try to implement an algorithm or ML solution that does this and you'll know how insanely hard this problem is.
The risk and severity of bad effects from COVID exceed the risks and severity of the bad effects from the vaccine across all age categories.

It is a low-risk, higher-reward proposition for everyone.

And even if all the virus does is fry your sense of smell you're better off with a few days of influenza-like symptoms from the vaccines.

I’m not happy with how Backblaze handled informing affected users at all.

They were aware of it on March 21 and said that they “were preparing a communication with affected users at that time”.

I received an email about that only yesterday.

That’s 52 days it took them to write me an email which imo just isn’t good enough and afaik does not conform with the GDPR requirements for data breaches.

Medical specialists were concerned about incorrect usage of masks, which may increase risks of infection. Later studies contradicted those fears somewhat.
You can't just weigh "The risk and severity of bad effects from COVID" with "the risks and severity of the bad effects from the vaccine". You also need to factor in that the probability of an unvaccinated person getting COVID isn't 100%.
Since it’s a ledger, the coins can’t be poisoned, but you can poison the addresses (in traceable blockchains like Bitcoin, at least). At the bluntest level, refuse to transact with addresses that have received money from poisoned addresses, transitively. In practice you probably want to apply somewhat more nuanced rules, or the poison is far too likely to spread to the innocent. It could even be weaponised, by a poisoned address deliberately sending small amounts to addresses that it wishes to poison, since you can’t refuse to receive a transaction.

(Incidentally also, there is a minimum unit, at least in all currencies that I know of; Bitcoin, for example, goes to eight decimal places. But yeah, each unit doesn’t have physical identity like bank notes do. Infinite divisibility is bad for efficiency as it means your data types have unbounded memory usage, so you’d need to put together a bunch of rules about how far you actually can divide things, and it’s just not worth it.)
Without the investment funds, where is the startup getting the funds to pay you 100k/year? Some startups take a while to hit big and the only source of funding is investors. Fair or not, there’s a power imbalance and ignoring that seems foolish.

Also, the view you have is biased to the rare success scenario. In the failure scenario, the employee comes out ahead since they at least got some amount of their investment back.

Also not all investors are created equal. Some investors are strategic partners who can help grow your business. They forgo a salary because they provide advice and a social network the founder can tap into at critical junctures. That’s extremely valuable in some cases. Not all investors play that role (or play it well) but it’s hard to estimate the value of investors ahead of time just as it is to correctly evaluate an employees contribution.
> the unvaccinated can simply go without a mask regardless of their status.

Oh, the humanity.
The bill will allow the government to nominate what content will be more likely to come up in recommended content - it doesn't empower them at all to specifically ban content in any manner they can't today.

As for that power - it can lead to bias but I'm pretty alright with it, it's likely going to be used to both stifle the organic spread of false information (i.e. anti-vax, flat earthers etc...) and it'll also likely be used to favor content that's supportive of the current administration (so if Harper got back into power it'd likely not include pro-climate change content). I think this is a pretty acceptable trade off when it comes to stumble-upon content - but all the content not endorsed by the system wouldn't be banned or removed.

The biggest downsides for me are the possible difficulty adhering to the guidelines for smaller platforms. I enjoy nebula and it's possible if unlikely that they may be forced to exit the market as a result of this bill - but bear in mind that any inherently Canadian content creators should be able to easily argue their adherence to the guidelines even if the CRTC tries to shut them down.
We aren't paying farmers to waste food, we are paying farmers so that big stores don't have shortages or have to increase the price of bread 10x over because there was a bad wheat season. With a 1-2 year lead time on crops, you can't afford to accidentally not produce enough food just because the midwest got a bunch of hail or flooding that year. People can't put off eating for a year while we grow more.

I agree crop subsidies are mismanaged and often way more is spent on crops that don't need subsidization, but without crop subsidization at all you end up with price shocks in the food market and potentially/inevitably shortages and famines.
The Community Corrosive Effects of CLAs
Thank you, will give it a read.
Yes, exactly. The reason why monadic concurrency libraries such as Lwt and Async is that the OCaml language does not support concurrency natively. If it did, we would have built something similar to the `ocaml-aeio` library.

Btw there is a modern instantiation of `ocaml-aeio` called `eieio` [1] which supports Linux's io-uring. Eventually, this will be extended to support all the modern I/O stacks on different platforms, and also support performing I/O on multiple cores.

Wow, people here really hate statistics. https://link.springer.com/article/10.1007/s10654-020-00698-1... ; if you're aged under 34 (as are the majority of tech workers), in the USA you're almost ten times more likely to die from "other acccidental fatalities" (0.0032) than covid if you catch it (0.004). Note that to assess risk the covid IFR there should be multiplied by the chance of catching it, to make it more comparable with the other columns, so if the chance of catching covid is less than 50%, then overall you're also more likely to die in a traffic accident.

And yet Scripps healthcare in California is going on more than a week of all of their IT systems being down for the same reason and it’s disrupting operations enough that they’re diverting a incoming patients to other providers and a lot of their patients have no way of finding out whether their already-schedules procedures will still happen.

Since healthcare is so heavily regulated it’ll be interesting to see what repercussions come of this. The company has been mostly silent on the matter despite it being severe enough that you can’t even get to their website.

Not here to say you're wrong but I think you may be interested by the book "Farmers of Forty Centuries" if you haven't already come by it, basically describing the amount of labor it takes to feed the population dense areas of China/Japan/Korea ~100 years ago off very small plots of land.

Basically the answer is a long growing season: getting 3 rounds of crops out of the same field each season, and keeping the dirt rich by collecting everyone's "night buckets" and preparing the hu-manure to turn nutrients back into the soil.

My impression is that growing produce and composting organic matter can produce more calories per acre than industrial farming methods, but the cost is labor, selling vegetables is only profitable with the petro-fertilizer methods.
