She's been the senior Senator from the USA's largest state for over 27 years. How many major legislative accomplishments has she achieved?

Some may name the Desert Protection Act, until one looks closely at the specifics -- it was primarily a vehicle for pork and to financially benefit her family.

Some may name the "assault weapons" ban elements of the 1994 Crime Bill, but that lapsed 15+ years ago, and its failure to accomplish its stated goals was so pronounced that even she hasn't moved it again.

Anything else? For 27 years in what should be the most prominent seat in the Senate?
> This means if you caught the virus early in the spread of the pandemic your odds of surviving are substantially higher than if you caught it right at the peak of infection.

I'd say your odds are best if you catch it some time after the peak. The hospital will be better prepared to prevent infections there and have more experience on how to treat patients best. There may even be some treatment that prevents the worst symptoms.

Also, if you (egoistically) try to get Covid-19 early, you may inadvertently infect others against their will.

It's true we don't have to invent every wheel. But it's also true that we don't have to treat invented wheels as gospel. There's more than one standard for living a good life, which depends on the person.
The problem is the high number of infections. The virus is having a run in a population that has no immunity, unlike a flu. So it is spreading fast and in large numbers. A tiny hospitalisation rate multiplied by a very large number of people infected may be more than the hospital capacity.

Which is why both of these statement can be true at the same time: this thing is no more dangerous than the flu to an individual if you get it, but it can kill many more people than the flu because the population doesn't have any immunity and many more people will get it.
Great to see progress in this space. I remember trying out G1 for the first time years ago and almost immediately noping out of it as the performance was terrible.

Working in low-latency space the angle for me is much more about GC latency (in microsecond-level scales).
I've never seen anyone doing a thorough evaluation of GC times across different implementations.

Community-Powered Productivity and Feedback
Funny you should mention Hook. When I first heard about it, I made another Alfred workflow (called Rabbit Holes) that allowed me to gather related files, notes and bookmarks under a particular subject.

It relied on unique id numbers for each subject and an index file that listed them. For instance, if I wanted to associate a pdf to the subject "Hypertext", I would:

1. Select the pdf in Finder

2. Run the workflow and perform a fuzzy search on the index file

3. Find the subject and select it.

Then, the pdf's filename would be prefixed with the code corresponding to "Hypertext"; finally, a master note for "Hypertext" would be appended with the link to that file.

(This workflow also used Dropbox though. It would have been easier if it didn't.)

If you use Alfred (with Powerpack), I'm sure we can think of something that may at least look like an alternative to Hook.

Autonomy and Agency.

Trust your people. Make sure they feel safe (not afraid) to make decisions and take action.

It drastically reduces the need for management. It makes people feel happier about their work, raises quality and reduces employee turnover rates. It makes it simpler to keep high skill people, which in turn makes it easier to recruit high skill people.

The counter argument I run across is that the mistake rate will increase. But that is simply not true. Through all my data I have never seen that happen. Generally the mistake rate goes down, and the cost of mistakes goes down a lot. And the cost of all actions goes down since fewer people are needed.

Couple this with transparency, asynchronous communication and decision making, and you have drastically reduced your company's management overhead, increased speed, increased well being, increased innovation, etc.

Depending on how philosophical you want to get, it is not so clear what exists and what does not. Neither it is absolutely clear what means to be discovered.

I think that ideas can be discovered. In my opinion, theorems, or more precisely the proof of these theorems, for instance, are discovered. In the sense that they are not an invention, they "emerge" from more fundamental definitions.

You seem to be of the opinion that the only things that can be discovered are those that emerge from the "real world", whatever the real world is. That is, I guess, an acceptable interpretation, but I do not think is the only possibility.

To give a very concrete example, chess rules do not exist in the real world, but knight's tours are discovered.

Following the link to libeatmydata that some hardware controllers use for asynchronous writes:

libeatmydata is a small LD_PRELOAD library designed to (transparently) disable fsync (and friends, like open(O_SYNC)). This has two side-effects: making software that writes data safely to disk a lot quicker and making this software no longer crash safe.

DO NOT use libeatmydata on software where you care about what it stores. It's called libEAT-MY-DATA for a reason.

Probably more to do with FAA regulations than anything else. You can't put more than a 100W batter in a laptop, and the charger is 100W (96W, I think), but modern processors and GPUs need more than that at full speed with all cores, leave along fans and SSDs and screens. My similarly specced desktop runs at 400W, not including the monitor.

So yeah, we seem to have hit a limit with traditional chipsets. Probably why Apple is going full steam on their own ARM SoCs. The iPhones and iPads out now can do some pretty serious work, just imagine what could be achieved by bringing that power to the Mac.

As you said, the complex numbers are the unique (up to isomorphism) algebraic closure of R. Given that they arise as the unique solution to (in my opinion) a pretty fundamental question about the real numbers, I think it's fair to say that they've been "discovered", not "invented".

Adaptive cyclic lockdown to suppress Covid-19 and allow economic activity
Experimentation in the Arena: Scott Mitchell [audio]
We’ve used online shopping for a few years now, not exactly the same as they deliver, but close enough since there is only a certain amount of delivery slots.

There was never a problem with getting a slot until the recent pandemic. My wife sat there pressing F5 but it wouldn’t be enough, new slots were taken exactly when they opened.

Turns out someone had a piece of software set up new accounts, registered slots and then sell them. The store chain fixed it after a few weeks, but those are certainly interesting problems we face with online “Queuing”.
That China censors and controls media is not wrong. The only reason we have the tank man video is because the journalist hid the tape in the back of his room's toilet.

What's really going on in China is guesswork to a greater degree than elsewhere. The communist party prefers it this way.

I've run into an issue where a Ruby library is technically thread-safe but there is some C library code that blocks (i.e. connect with TinyTds). This makes it practically unusable with threading under special scenarios where your SQL servers are not guaranteed to be available.

A good implementation will calculate the estimated "cost" of a given query before executing it. This is quite tricky to do well, and I doubt many people do it. Once you know the cost of a given query, it's trivial to reject it if it's too expensive.

A much better alternative is to only allow specific queries in production. These persisted queries can then be assigned an ID, and making a request is a matter of sending the ID with any variables.

Though my understanding is that the survival rate of a covid19 patient once he requires a ventilator is around 50%. If that's true, at worst, if we ran out of ventilators, the death rate would double. That's bad and we should avoid it but the doubling of a tiny number will still be a small number.

Which is why I am still confused by the ratio of 1:10 that the White House has shown between the death toll under lockdown vs no lockdown.

For the reason above, I would only expect the death rate to double. No lockdown means a lot more people get infected faster. But lockdown still requires to build herd immunity, we are only slowing it down. So the same number of people will get infected ultimately. So either they implied that the lockdown would be permanent until we get a vaccine (at best 2021 Q1), or it completely disregarded what happened after the initial few weeks of lockdown and then the numbers were at best grossly misleading.

Apparently 60% of the population should use these apps in order for them to be effective, which turns into 80% of smartphone users.

In Singapore the uptake of the TraceTogether app has only been 12%of the population, and the city ended up in lockdown anyway.

Making those apps opt-in, i.e. optional, is taking a big risk. At the same time deploying a system that works at such scale in such short time isn't easy.

When solar system planets formed from stellar dust, do we assume that said dust was uniform in composition and merely position, solar dynamics and interplanetary dynamics such as collisions (formation of Moon) led to the differences in chemical composition?

For example, it's the outer planets that are gas giants. Venus composition doesn't seem too different from Earth but it's much closer to Sol, so it's more exposed with much more energy absorbed etc.
To be fair, so is the rover.
> The same for negative numbers, for that matter.

It might be expressed differently, but the concept of addition seems very fundemental, and additive inverses (negative numbers) are a very real part of addition.

> It's silly to think that the sqaure root of negative one is something real to be discovered

If we assume the aliens also have a need for multiplication, combining it with multiplication we get polynomials, and to factor polynomials you need complex numbers.

Besides, if they think of quantum mechanics they'll surely need some way to express what we call the complex numbers too.

Even if they don't think of them as "numbers", they'll absolutely discover analogous concepts and theorems.

That SSD analogy is wrong. Doubling the capacity doubles the lifespan of the device. The reason why there is extra space is because performance of a full SSD can degrade to unacceptable levels. Basically you can write and erase but you can't overwrite flash. If the drive is full the writes are queued in the over provisioned part of the SSD and once the garbage collector has run and freed up space the pending writes are transferred back onto the regular storage.
And not all of them were even planets, either.

Not really, because the standard is what defines the language, just because GNU Fortran does non conforming stuff it doesn't mean that for example PGI Fortran would do the same non conforming behavior.

By the same measure I can assert that C++ is a memory safe language given that Visual C++ enables bounds checking and iterator invalidation in the standard library by default.
