Just yesterday I finally got to running actual tests of graphical performance between my host (Windows 7 Ultimate, NVIDIA GTX 950 - not top of the range :)) and guest (Windows 10 Pro running inside VMWare Workstation 15).
Used "PerformanceTest 10" from Passmark. Host scored 6015, ran all benchmarks nicely. Guest scored 1645, only ran some benchmarks (due to lack of Dx12 and compute capabilities), and even those were penalized.

Virtualbox guest didn't participate in the contest, as I find graphical performance of VBox guests noticeably worse.

I must add though, that for desktop tasks VMWare Workstation performance is absolutely adequate, able to run double 2K monitors wonderfully. For gaming setup I'm personally planning to play with PCI-passthrough. The only problem is not to get lost in the tinkering, before playing any actual games :)
No, they would just click anything that makes that dialog that stands between them and their goal of installing the app go away without reading the text and then be unhappy that their battery drains. Any design that relies on a confirmation dialog is fundamentally broken. Even technically competent users will read most confirmation dialogs as „Let me do what I want [Abort] [OK]“ no matter what you actually write there.

In many situations we may not have better solutions, but that doesn‘t change the fact that this is terrible.
As the author notes in the article, all this takes is basic knowledge of physics units, and the only math required is addition and multiplication. So it’s a matter of basic skills to some extent, but that’s not really the key.

The way you get better at this is by doing it, a lot. Every time you read such an article, or some one relays such information to you, run the math through your head as much as you can. Make notes of the things you don’t know that prevent you from pushing the thinking further, and methodically learn about those. Don’t think of yourself in terms of particular labels - eg “I’m not much of a physics person” or “I’m a software guy” - your job is to understand the world, solve problems, answer questions.

It’s a constant effort and it’s not easy. It helps to surround yourself with others with the same drive. It helps to teach, as it forces you to constantly reassess the fundamentals, and the common mistakes beginners make (see Feynman’s writing on that topic).
can you try to go in Settings -> Swipe zones and change the trigger size? And then try to grab it from those triggers?

Thanks!
As it was said elsewhere, you present yourself as the stupid person version of a smart person. Maybe it is true, maybe it is not.
The name for what you and the parent described is a review paper. I can't speak for Math or CS, but in life sciences the following techniques would work:

1. Search X and sort by citation count. High quality review papers get cited A LOT, typically in introduction sections of primary research papers. Alternatively, google "[X] review" or "best review paper on X".

2. Look for review journals. Many fields will have journals who only publish reviews. Nature has several such publications for example.

3. Look for the top journals in the space (start by sorting by impact factor) and see if they have review sections. If they do, try to search those sections. Most journals will reach out to top labs in a space and request that they write a review on a subject if the journal editors feel one is needed.

4. Ask someone in the field. Any researcher should be able to immediately point you to canonical reviews in their space.
At one point, there will be only sourcecode to read. Read what the best programmers actually do use.

Michael David Crawford protested a Hacker Dojo event by calling the fire department and pulling the overloaded traps the computers were hooked up to. He claimed nothing would ever come of the projects being developed and that they are using the hackers to get ideas.

The whole point of a hackathon is to have hackers meet VC people.
Given your name, I guess you live in Japan, so I'll just give my opinion for others who have never lived here. I also think the title is misleading, though I wouldn't express it so dramatically.

One thing to consider is that Tokyo is a prefecture, not a city. There are rural areas of Tokyo (like really rural), though most of it is very suburban. Anybody who has lived in the suburbs in western countries would probably be fairly comfortable in most parts of Tokyo prefecture.

It is true that in quite a few areas of Tokyo it takes a long time to get to central Tokyo. 2 hours is at the extreme, though. I live in very rural Shizuoka prefecture and I can get to Tokyo station in 2 hours if I time the bus and shinkansen perfectly. If you are on the train line, most places are no more than an hour away. It's pretty comparable to living in satellite cities in London, but the train is much better :-)

If you are not on the train line, though, it can take quite a long time. Roads in Japan are very slow, especially in rural areas. It's not unusual for it to take me over an hour to drive 30 km or so if I need to go through several towns. So you definitely can find houses in Tokyo that will be 2 hours away from the city center, but I don't think anyone working in central Tokyo would buy those houses.

I honestly don't think the example picture is representative of houses you'll find in Tokyo prefecture. They definitely exist in areas that are desirable, though. I think saying that you're probably looking at either a 1 hour commute by train or your are going to get a house jammed in wherever it will fit is correct. But it's not both at the same time.

I don't often go to Tokyo, but I occasionally go to surrounding areas. Probably if I was looking at houses for commuting to central Tokyo, I would probably look at places in Kanagawa, Chiba and Saitama as well as Tokyo. There is actually quite a lot of choice.

The video linked in the article is well worth watching (as is anything from "Life Where I'm From" if you are interested in Japan) and is extremely balanced IMHO. Compared to other big city centers around the world, Tokyo and the surrounding area is quite affordable. Compared to Silicon Valley it's almost comically so, but Silicon Valley is really right at the other extreme.

What subject excites you that doing a course on Coursera or Udemy, for example, doesn't make you feel like, "Groan, 6 hours a week x 6 weeks?!"? Do that course + talk on the Coursera forum with other students and reach out to folks in the industry who'd value seeing that certification on your resume / LinkedIn.

About feelings: you have to feel your feelings, but productivity is difficult if you're always feeling down. Don't beat up yourself, which adds a 2nd layer of sadness to an already sad situation. Get enough sleep and work on things that excite you.

More generally twitter has spent the last 14 years painting itself into a corner.

It seems the world need a massively scalable messaging backbone, and when twitter was created I thought (IIRC, this is a decade ago and I can't remember if and where I wrote it down) something like that would happen:

Basic Twitter would stay free and there would be all kinds of paid services on top:

- it could be extended to allow APIs for machine to machine communication.

- it could be improved to be used for groups and one to one messaging (WhatsApp, later Telegram took this market. Google+ had a decent chance to get a slice of another part of it.)

- they could charge for API access or for more than what clearly personal usage (more than a few groups, multilanguage distribution, near realtime machine to machine communication etc)

When I think about it now here's another one:

- paid subscriptions to feeds. Examples: news feeds (maybe you pay for access to your newspapers)

Instead they become what I would describe as a spam distribution machine where you can follow celebrities.
Reproducible builds are not a "perfect" solution.

They, and the source code to build them, is the baseline requirement for any trust in what is being provided to people.

The Australian government has a history of extreme incompetence with IT projects, using PR to try and effect adoption, then bullshitting about their failures.

If there's evidence this project is going to be any different, then great. :)

In the meantime, I'm judging them based on their historical actions.
How does it work with futures?

My understanding is that I buy a contract for 100 shares at a future date of my choice.

So let's say stock XYZ is currently trading at $20, and I buy a futures contract for $100 for Jan 1st 2021.

I don't have enough money sitting around to buy those 100 shares, so let's say XYZ is trading at $200 by Jan 1st 2021, That means I have a contract where I can buy 100 of them at $100 and immediately sell them for $200, so in theory it's a $10k profit.... but because I don't have enough money to actually do that, do I just sell my future for something close to 100* $200 (because someone with enough money will buy it and do the actual trade?)

What happens if it's already well over $100 long before Jan 1? Can I just set a price and sell it whenever I want like a can with a regular share?

A hackaton can be a fun excuse to experiment with random, but when I learned about the pan european hackaton against the corona virus organised by the EU commission I didn't know if I should to laugh or cry. Its like children playing doctor:

>It's just a fuzzy idea.

Well I'm sure it proves your point, whatever it is, and definitively wins your argument, hands down. Who am I to question such extreme self confidence? I graciously concede. Congratulations!

>Yeah I figured you might get pissed off. Note that it was nothing personal, and none of my comments (other than the sarcasm above)

Why I'm not pissed off at you at all, and I don't mean for you to take any of this personally, and I non-apologitically apologize for you choosing to be offended by any of my words, plus I give you the full and sincere benefit of the doubt that you would never retroactively claim you were being sarcastic, simply because you didn't want to admit you made a mistake. Who in their right mind would ever do something like that, in this day and age? I'm sure your brilliant idea is good enough to win the Noble Prize in Journalism for curing Coronavirus by injecting bleach.

>No who are those guys. Never heard of them. I only know about Mark Zuckerberg, Elon Musk, Jeff Bezos and Bill Gates. That's all I know.

Yeah, I didn't think you knew who you were criticizing, or even had the curiosity to google them.
Not at all. I appreciate a few hedonism treadmills myself, though they usually don’t have the same price variance as wine.
Many problems require lots of huge matrix multiplications—think simulations of physical systems, i.e. weather systems or molecular interactions, or numerical optimization.
Not an edit war, but I was amazed at the time about the discussion over the name of the Río de la Plata article, which just went on and on and on. I didn't contribute. The article at the time was just a tiny stub. https://en.wikipedia.org/wiki/Talk:R%C3%ADo_de_la_Plata/name
Exposed to SARS-CoV-2? Absolutely, no problem.

Exposed to god-knows-what in their untested vaccine? Absolutely not, even five years after release ("my body, my choice"). There is a long history of contaminants in biologics, and vaccines in particular. Problems like GBS (Guillain-Barre Syndrome), tumors, polio, and who knows what from PCV. If I recall correctly, wasn't SV-40 injected into 25 million Americans, and perhaps hundreds of millions world-wide? Well-tested and analyzed vaccines like BCG I have no problem with, but being a guinea pig for whatever was cooked up in a rush over the last few weeks? Count me out.

The headline has it backwards -- the more significant (unbounded) risk is from the therapy, not the SARS-CoV-2 exposure.
I wanted to thank everybody who took the time to explain this. Thank you.
Any textbook exposing this mathematical formalization with rays? I'm interested by the mathematical aspect as well.
This sounds like the same feature that Intel's C compiler used to "cripple AMD" by switching to a slower code path when it detected that the program was running on a non-Intel CPU.

if the sun, which is huge compared to the earth, were the size of a pea, the nearest star would be ~120 miles away to scale. this is a typical distance between stars and it’s why when andromeda collides with the milky way there is little chance of stars colliding.

A semi decent amateur telescope (I recommend starting with a dobsonian) and a drive to an area with low light pollution (perhaps the harder requirement) will fill your eyes with the many wonders of the night sky, M31 (Andromeda) included :)
Interesting. The SQL concept of null always made perfect sense to me.

Two people with the same middle name would have equality with respect to the string value of middleName. The same applies with two people known to have no middle name—where you store a zero length string.

Two people who didn’t supply a middle name should not have equality with respect to middleName. Hence null. This acknowledged lack of data cannot be equal to a different lack of data.

Aside from Shor's, the other is Grover's algorithm which deals with search in an unstructured database. There are more and more superpolynomial speedups which have been discovered in application of QC. A good enumeration of these is the quantum algorithm zoo.

The thing I don't understand about qc is how on earth can you read values from qbits without breaking superposition.

Oh really? How much of your time has been spent on what brand of salt is in your pantry right now? What informs your type of shampoo in your bathroom? How much weight would you say your friends or colleagues experience with a car brand has influenced the decision you made to purchase one auto manufacturer's model over another? Advertising works and if it didn't it wouldn't exist. While I do understand and am with you on your philosophy of making an informed decision, so much of our impulses as we purchase the things required to live daily are influenced by ads whether we're aware of them or not.
IRC has no message storage - so not only it has no IMAP, it has no POP3 either.

And IRC is a horrible transport protocol because it handles errors by dropping messages. SMTP has both message-ids and explicit confirmation response to make sure that as long as server comes up, eventually, the message will be delivered exactly once. IRC does not; so it is simply not appropriate for the cases where each message matters.
I grew up in the piracy era, if the code is possible to get and I want it, I get the code and do what I want. What is this license everyone keeps talking about? Never read one of those. Seems like a lot of wasted time and energy to me. I'd rather use that time and energy to building something cool. If I gotta be anon to do that, I'm black as night. This legal shit is for bean counter types. I get shit done for a living.

> the transmission rate dropped again, to the point where any single case led to less than one more. Once that happens, an epidemic dies.

Note that this can take a while. What the article suggests - getting back to the containment phase - is the stated goal of some countries. However, to get there quick you need very drastic measures. With the measures we adopted, it will take a bit of time - I read one estimate that the reproduction number in Switzerland has been around 0.59 since the lockdown was enacted, so you'd expect cases to drop by a factor of this per generation - it still takes weeks/months to go from 1000+ cases to below 100 (where they estimate they have enough resources for contact tracing).
I obviously didn't flat out ask others if they had tried it. I either mentioned that I had tried it or played dumb and asked if they knew anything about e.g. microdosing, as if I had only heard of it.

Anecdotally...

1) Friend from college working in machine learning space who just moved back to SV from Asia, saying that the tech culture in Asia suffered from a lack of creativity. In the same conversation I brought up having used psilocybin and he freaked out, thinking it was going to damage my brain.

2) Another friend from college who's a hardware engineer. who found it strange that I didn't want to drink whiskey with him but regularly use psilocybin. He also warned me about brain damage.

3) Friend from work whom I knew socially. After he quit working, I chatted with him and suggested that if he wanted to try psychedelics now would be a good time, before he decides whether to go back to working. He seemed to be surprised, and just made a comment about Steve Jobs to cover up the awkwardness.

4) Another coworker I worked closely with and had a good opinion of me because of the work that I had done, who had gone to another company. I asked him if he knew anything about microdosing while having lunch and he said not to try that stuff because it would mess up my head.

5) The Burning Man guy was someone I'd worked with before. He told me about his recent BM psychedelic experience after I told him about having used ayahuasca recently.

Point is, my experience of sampling people I know in SV both socially and professionally hasn't yielded anything close to "yeah I have used psychedelics to help my work" even when I didn't ask them straight up if they had used it, and instead volunteered my own experience first.

I worked in large companies in South Bay, not SF-based startups. That probably had something to do with it. Still, all the press about SV and psychedelics gets tiring when it seems not to take into account the likely uneven distribution between South Bay vs SF and large companies vs startups.

That's pretty neat. I wonder if anyone can help with my use-case. Basically I want to replicate netlify's [1] "deploy-previews". Hopefully I can get it working some day.

The action runs on a PR:

1. runs build

2. create static-hosting subdomain, e.g. "pr-233-myrepo.mysite.com"

3. upload build to subdomain

Subsequent commits to the PR: simply rebuild then upload.

Anyone know some ways to achieve this?

I do think majority of the effort should be spent on protection from hacking, but dismissing other very real attack vector as entirely hypothetical is just naive.

Last elections were decided by 80k votes, in a country with 250M eligible voters. With such a tight margins we have a lot of valid attack vectors, not only most obvious hacking ones.

Effective organizations are (and should be) able to deal with many risks at once. Do you think that during Cuban missiles crisis all other investigations stopped, and 100% of CIA, FBI, Police, Army etc focused on Cuba?

1) As other comment said, the C14 is produced in the atmosphere almost at a constant rate, and it decays at a constant rate. So as an approximation you can suppose that the concentration of the C14 in the air is constant. When the C14 is inside a dead body it is not longer replenished, so the concentration decrease slowly. [Note that the concentrations of C14 in the air actually changes. You can see in the Wikipedia article a table to fix the differences.]

For recent times, you can also compare the dates of the C14 with other methods like counting tree rings, or the date of a total eclipse and check the calibration.

2) You are almost right. The tides are not produced by the gravity of the Moon, but from the differences in the gravity of the Moon in the water that is nearby and the average of the Earth.

You forgot to include the centrifugal force [when you are in the non-inertial frame frame that rotates like the Earth-Moon system https://xkcd.com/123/ ]. The centrifugal force is bigger in the water that is in the more far from the Moon and again the difference creates the other tide.

3) The sky is blue because the single molecules in the air disperse the blue/violet color more than the other colors. There are many ways to produce colors. In this case the light is dispersed by the whole molecule.

A different method to produce blue is using a CD to produce a rainbow and the using a slit block the other colors. Some birds and butterflies use a somewhat similar method. [Not very similar but closer to the CD method than to the air method.]

The blue in the die for cloth uses another method. You make a long chain of conjugate chemical bounds C-C=C-C=C-C=C-C, and pick length and atoms so the electrons absorb the colors you don't like and transform the energy into heat.

I'm probably forgetting a few more method, there are many of them, so it's interesting to understand which of them make the sky blue.

*) These are good questions. My explanations are not 100% complete (and probably not 100% accurate) but I hope you can fix the holes.
