That guy who edited babies no long ago is one of it, apparently he raked in hundreds of millions of both government and private investment, claiming he invented an industry-leading gene sequencing machine that in fact is a failed US product he bought from his professor.

Also, Huawei in their early ages stole one of Cisco router's source code and priced out Cisco with an exact same product compatible with Cisco systems, one Chinese academic invovled in modifying admitted it in an article. One of the role model stories.
The conclusion is correct. It doesn't rely on the moon being a black body radiator, but on etendue, which shows that the most you can do with a system of lenses and mirrors is to create an environment (on earth) as bright as the environment on the moon. The fact that rocks on the moon's surface only reach 100°C shows that an environment like that is not bright enough to light a fire.

The main issue I have seen with the smaller divisions is that they manage to do thing worse while not providing any true accountability because they are too small to be watched effectively and lack the oversight infrastructure of larger organizations - which is really saying something given how infamously ineffectual the watchers are at watching themselves.
Indeed, you can not focus all of the sunlight that would hit a square mile of Earth down to a penny. You just can’t. When you focus the sun, you’re not making an infinitely small spot, you are making a tiny image of the sun. The bigger your lens, the larger that image. You can’t get any more focused than “in focus”.

When you focus a cutting laser, you are imaging the shape of the laser cavity. The emission is coming from a very narrow spatial region, so you can focus it back down to a small spot. However, a laser that is out of alignment, will often not be able to be focused to a small spot.

I second the importance of 2,after the work drink or no-blackjack "behind the scenes" for its where the real business is, the rest is just the "acting". I agree in pointing the importance of the reason he/she was granted that position. Chances are parent is considered smart and polite and capable enough to be there, so maybe parent should just use his skills and go directly to open his company, or don't stay too long there, don't get used to be a shadow, even if you make good, comfortable bucks, if the desire is to open one's own company. Anyway, if the best thing if you are not just procrastinating in opening your own company is to go to your friend who owns 25 million bucks company and ask him if he would put some of his hard-nosed earn money in your plan for a company. Ask him to tell you as honestly as a friend can possibly be honest in this word, why he will not put the money that costed him his blood and sweat in your plan for a company. His honest answer would be enough what you need to learn from him in relation to opening this specific company you plan. Moreover, Whenever and wherever you see the word "opportunity" , be aware "opportunity" is a dangerous word, and all scam in the world comes from the word "opportunity".
They still giving out sensors? Not sure I live far enough away from you to merit another for the study, but worth an ask.
Any idea why they developed Flashlight for this, instead of using PyTorch?
It’s still profoundly disturbing to my eyes.

Technically their underlying problem is relying on IP ranges, wich is flawed and raises false positives all the time.

They seem to recognize they shouldn’t be doing irreversible and critical action with only that info, yet will still use it to drop traffic.

To me their message is “sorry we screwed with your accounts, going forward we’ll only screw with your messages”. Am I supposed to be that reassured ?
Reports from the affected are a bit imprecise and often heated. Do we know whether Slack here banned based on IPs from the past and if so, do we know how long they keep that data?
On steam, most people don't want to use the in-game friends client even though it looks a lot like discord in style (when you get to the chat rooms). Not sure why that is, but Steam Chat most definitely lost to discord.

"magic numbers" aka memory addresses where CPU registers were visible

Anyone who has done some amount of programming with microcontrollers like the 8051 or the Microchip PIC will not find such things unusual; when everything is integrated into one unit, the difference between a register and a memory location decreases.

Of course, if all you've ever known of are the bland RISCs they love to teach in CS courses, then all this is very weird and foreign to you... but it's just a natural consequence of how the hardware was designed.

As such, I do recommend glancing around the documentation for actual computers, from 4-bit microcontrollers to 50s and 60s mainframes, to familiarise yourself with the overwhelming diversity of existent computing devices.
Waymo is the only driverless car company that I even remotely trust.

I went to a conference where Uber was presenting, two months before the incident where they killed a pedestrian. Their entire presentation focused on providing a public service to improve safety. It was so over the top on feel-good-make-the-world-a-better-safe-place, you couldn't believe a word of it. If they really cared about safety, they would be adding safety features to cars already operated by humans (e.g., automatic breaking, warnings when you veer out of your lane, cameras, etc). They wouldn't try to take the giant step of removing the human.

Their presentation was such BS, that it was clear they couldn't be trusted. Then two months later, it was confirmed.
Some features that I find elegant in Bazel, but probably don't have that much impact on small projects/teams is the whole concept of "visibility"[1]. For large projects, being able to control who can take a dependency on your code is really nice.

Which is why you should contain things to your own property. Set off an alarm as soon as the package moves. Sending a secret device/camera out to, potentially, the crooks home invites danger.

At a very base legal level, such actions may require a PI license.
I mean you can just take white phosphorous to a warm place and let it spontaneously combust.

The use case would be materials that don't burn at the Earth's surface temperature, but do burn at the Moon's peak surface temperature. But you could probably get those hot enough just by rubbing them or something.
That was a very good read. Thank you very much. I purchased the Kindle version of "The Dream of a Ridiculous Man" after reading this.

I have never read Dostoyevsky before. Any recommendations on where else to start?
No, that was pretty blatant Keynesianism [0]. Although I suppose if it is possible to be a Nazi apologist in 1919 then maybe I can be one too.

I did admit it was complicated. But the state of the economy was clearly a contributer to the rise of the Nazi party. It isn't like Hitler got in because the Germans just went crazy one day and thought the dude was a great guy to lead. He got in because the country was collapsing anyway.

Isn't that particular feature mostly implemented server side?

On the other hand, yes, I agree that modern messengers has a lot of features that my IRC clients missed (voice comes to mind). Also they are easier for mainstream users to use and administer, and, compared to old IRC, safer in a number of ways (although I'd add that we are seeing a number of new threats now).
It's not because the moon is a spherical surface. If that were the issue, there would be a bright spot on the Moon where you can see the reflection of the Sun (you can see such specular reflection spots on e.g. many cars), and you could use that spot to light a fire. The issue is that the Moon barely reflects any of the light that falls on it. Most of the light is scattered, and most of the rest is absorbed and re-radiated.

No, it means "spitting sparks". Like you see coming out of the control panels in the original Star Trek, when they got shot by Klingons.

The Roman empire collapsed, the Soviet union collapsed, numerous South American, Eastern European countries collapsed, the US economy crashed in the great depression. None of them resulted in anything remotely resembling Hitler's Germany. Hate is an emotion. It can be stoked by class resentment and injustice, but it's quite a different thing. Hitler harnessed hate like few societies have seen before or since.
A whole slice of Japanese workers’ have life that squarely fall in “poor and dull”. The overworking cliche is only true to an extent, but still working poor people are plenty and their number rising could arguably be the main factor in the population demographic change.

We would write the number out for you, but it would fill up thousands of pages, give or take, and look like this gigantic zip file.

It's ironic to see that 11MB file being called "gigantic" in this day and age; many web pages are now unfortunately much larger, and the page of the article itself transfers at least 1MB of data.
Are you joking? It provides no specific action they're taking to prevent this type of thing in the future, and it's internally inconsistent (who are "the people whose accounts we intended to disable" who they "will not deactivate their account and they will be able to access Slack when they return to countries or regions for which no blocking is required"?).

I've spent the day messaging and talking with friends who work within Slack in an engineering capacity who feel, frankly, betrayed by the organization. Slack advertises itself internally as an engineering-driven company and on the security side, has an incredibly elaborate system of internal controls that I have espoused emulations of during my consulting that, and I am being very specific without being too specific here, were bypassed to perform these account bans. Slack's security team was bypassed. Slack's internal controls were contravened. Slack has demonstrated that they can access every location you've ever logged in from and will cheerfully give that information up for the pleasure of the US Government without it even being required of them.

Leaving this comment to make sure that others don't get confused by your response.

1. As you mentioned, the moon acting as greybody absorbs part of the radiation and scatters the rest. In the second sentence you mention that the moon's temperature is enough to describe this radiation. In the third sentence you mention that you don't need moon's temperature to do that. So which is which?

Correct answer - to describe re-radiated energy we need moon's temperature, but to describe scattered we don't. We can ignore re-radiated, since it is not visible light and not hot enough. We can use scattered, since it is visible and hot enough.

2. Not sure why it is "No" if you are agreeing with me. Also not sure what you mean by temperature represented by total radiation (as you mentioned in part 1 there are two parts - re-radiated - at temperature of the moon, and scattered - at temperature of Sun).

To see that there is a problem with your argument - first note that the spectrum of black-body radiation dominates spectrum of grey-body radiation [1] (i.e. if black-body radiation is not in visible spectrum, the grey body will not be in visible as well). Then think that at 100 degrees C there would be no visible radiation. So the light that we see from moon cannot be this cold. Its coming from sun and it is hot enough (since it is in visible spectrum).

Cambridge Joins Cities Requiring Civilian Control of Police Surveillance Tech
Nope sorry. Slack is a walled garden. And relying on a walled garden means handing over your control, freedom and privacy which eventually gonna lead to similar kind of exploitation/abuse.

As another HN commenter @SamWhited put it, "Using a proprietary protocol that doesn't allow any form of federation is an unacceptable way to build a global community". We need to develop and use FLOSS protocols/tools as much as possible.
I haven't done material physics in depth, so can't be 100% certain of this, but I don't see how that can be true. Electromagnetic reflection is what results in either specular reflection or diffuse reflection (i.e. scattering), not absorbing and re-radiating. Which is why the color of reflected light is dependent on the color of incoming light, and not on the spectral frequencies of the material (unlike re-radiated light).
I believe there are unapologizable offenses that reveal true intrinsic character character flaws that can't be regretted away, but this definitely isn't one of them.
Can you describe what black-blackbody and white-whitebody are?

you won't be able to make your object much hotter than that.

I'm bothered by the modifer "much". If you are indeed talking about a physical principle, shouldn't this be an absolute limit rather than a suggestion? How much hotter does physics allow you to go? Are you sure it's not enough to allow ignition?

Along those lines, I'd assume that the surface temperature of the depends on the moon's shape and thermal conductivity. If I were to change the moon to be an ultra-thin and highly heat conductive hemispherical shell rather than a solid sphere, I'd assume the surface temperature would drop.

Assuming the amount of light reflected remains the same, does this imply that the maximum achievable temperature on earth with a magnifying glass drops as well? I don't see any physical reason that it should, but your logic would seem to imply that it must. Can you explain?
Four rounds of interviews is not that many nowadays in 2018. In the past 2 years before I landed in my current role where I'm happy with, I went through about 8~10 rounds of on-sites like that (spread out over 2 years) before getting an offer. I have 13 years of experience in Silicon Valley with a CS degree at a Top 50 university (Top 10 public) and I'm not even seeking leadership positions, just IC, and in some cases just interviewing for mid level.

Anecdotally, trends in recruiting in tech startups have gotten strange. Companies nowadays like to complain about shortage of talent, but interviewers like to be super picky (I've been on that side of the fence the past couple years, to witness the passing of perfectly fine candidates who just didn't get A+ on the interviews by other interviewers). In 2008 I would interview for 2-3 companies and get an offer. In those days I also interviewed candidates for the employer and ended up hiring a lot of great engineers, whose interview performance would not be considered good by standards nowadays (but they did end up being perfectly good devs in the company we ended up hiring them at). Those days are mostly gone. FAANGs have popularized being extremely picky at hiring and smaller startups picked up on this and believe it to be the right way to hire.

It's a messed up situation.

This description makes me wonder. There are lots of games who have huge amounts of depth like Paradox's grand strategy games. And they also claim the "tell your own story" environment, reasoning that the depth gives the environment that you can use to tell a story. So kind of the opposite of what you say being required.

Why do you think depth is not a requirement for this self story telling game? Isn't it getting boring quickly?

Trying to follow your argument. Suppose we put absolutely reflective mirror on the orbit. Since its absolutely reflective its temperature will be 0 Kelvin (in theory, very low in practice - there is a reason solar bound spacecrafts are covered with reflective surfaces). So we would not be able to use the light it reflects to heat anything?
>Correct answer - to describe re-radiated energy we need moon's temperature, but to describe scattered we don't. We can ignore re-radiated, since it is visible light and not hot enough. We can use scattered, since it is visible and hot enough.

When dealing with a gray-body, the equillibrium temperature of the body will be equal to the effective temperature of the incoming light, which will be equal to the effective temperature of the re-radiated + scattered light, since at equillbrium energy out equals energy in. So, assuming the moon is a graybody (and most objects tend to be roughly graybodies), we can use the surface temperature of the moon in our calculations instead of the effective temperature of the light that falls on it.
Apparently SC realized they can make a lot more money if they never actually released a game. I guess they're big fans of "The Producers".
