8x as much light as the moon is the same angular diameter and 8x more reflectance, or the same reflectance and 8x as much angular diameter. I suppose they could mean "8x as much reflectance but an unknown smaller insolation equivalent", but then they might as well say "we're putting a big spot light on a high-altitude balloon".

The relative sphericity of the moon is nearly immaterial here: when the moon is in full phase, do you see notable dimness around the edges where less sunlight is reflected away from you? Increasing the albedo to a near-perfect mirror cancels it all out.
Perhaps. However, that's not the same as taxes and its not a hidden cost like a tax. It's not factored into the price of US goods as US companies would use a private shipper if the this law significantly effected shipping costs.

At worst it hurts USPS revenue and increases the cost of first class mail as market forces can't compete for first class mail. My point is a lot of the comments are misleading about the scope of the costs involved here.

The most important science policy issue in every state
Interestingly, until now, "light pollution" meant artificial sources. (i.e. with different colour and spectrum signatures such as CFLs, LEDs, etc.) Florida Atlantic University studies the impact of light pollution on plants[1] and animals[2] but I suspect many studies only partially apply to something like what Chengdu is doing because significant solar (or lunar) light pollution hasn't been available to study.

Just a few concerns off the top of my head that I hope Chengdu will consider or at least study if it moves forward with this: circadian patterns, melatonin production, restful sleep, feeding patterns of nighttime predators (even in cities) including exhaustion of food sources (e.g. insects) that would naturally be difficult to find.

Well this will probably improve human and traffic safety, but seriously hurt astronomy and dark sky appreciation for those who live there. And it's a given that all-seeing surveillance footage resolution will be improved!

But the Financial District was much emptier at night historically than it is now, so I'm not sure this is closely linked to the article's claims.
For my part, I think it's worth considering that how perfect a plan has to be to implement should be a function of how readily it can be adjusted to match changing requirements. An MVP SaaS product is pretty tunable.

It's possible that local tax policies, particularly as mandated by and only changeable by plebiscite, might be slightly more difficult to adjust (win an election, get one chance every two years) to changing requirements or to handle undesirable effects.
This is the removal of market manipulation (subsidies on shipping). We should see more innovation because the market can act freely now. For instance, now that China will have to pay for their full shipping, some product may increase in cost to the point where they could be manufactured and sold in the US, spurring innovation. The fewer artificial market constraints the better.

> Finally, the greatest American innovation is democracy, the belief that all men are created equal and that's what leads to prosperity. That innovation has resulted in an explosion of peace and liberty unlikely anything the world has ever seen, and it has, as a secondary side effect, brought an explosion of prosperity unlike anything the world has ever seen.

Yeah, I don't know about that. Maybe in the US we've had a decent run of peace (with 50 years of nuclear holocaust hanging over our heads), but we've definitely dropped a lot of bombs on people. Enough that I think we can say that US democracy has not "resulted in an explosion of peace and liberty unlikely anything the world has ever seen".
Can you give practical examples of what you are mentioning? Like, how to achieve ""static builds"" with python? Got me interested!
I don't get your point, you probably aren't sarcastic? The wealthy effectively do write tax laws for themselves, through their capture of the congress, and the use of divisive social issues to trick poor people into voting to cut their own social safety network.

V8's timers have nothing to do with this, given the API doesn't give the data to even do any timing analysis on.

The accelerometer is limited to (IIRC) 25Hz without a permissions prompt. IIRC, at that sampling interval, you can't even distinguish between a phone being held in a hand and a phone in a pocket, and I know the decision to go with 25Hz was done on the basis of various studies. From memory, some study failed to get numeric PINs from full-screen entry at 60Hz, and a typical on-screen keyboard requires much more granularity than that.
So if these 50% will be less than a living wage (due to extreme inflation for example) you become slave? At least at Worryfree they were fed.

1. Everyone makes mistakes. Everyone breaks things. Happens at your first job, happens after 30 years. A good organization will have processes in place to prevent massive damage. You can learn techniques to limit damage of mistakes (from testing to resiliency).

2. Your knowledge is limited cause you're 23. No one hiring you will expect your knowledge to be massive. It's expected.

3. What's the worse that could happen? In most jobs, not that much. A feature doesn't work? Oh well, that happens, fix it in the next release (and QA should've caught it anyway).

Politics in a democracy has always disgusted everyone.

Or more succinctly put - context matters.
The first 30 mins describes the electronic warfare part of the WWII strategic bombing campaign in Western Europe.

Personally, I think it explains part of it. But certainly the, in retrospect idiotic, idea that unescorted bombers armed with machine guns would be a match against fighters played a major role as well.
Waiting is a risk that may pay off, so that 35% write off still changes the math.

Suppose you are going to make a coin flip bet. On heads you win 1$ cents tails you win 0$. That's worth ~50 cents. Now, suddenly on tails you get 35 cents. By reducing the downside risk it's more worth it to make the bet (67.5 cents).
>Imagine a world with double the amount of people living in it.

I find it mildly disturbing that the author assumes everyone reading this sentence is going to agree that it's an ominous prospect. Obviously, the implication is that it would be a world of fourteen billion people the vast majority of whom are on the brink of starvation, but we've (as a species) overcome Malthusian obstacles before. Why shouldn't having as many thriving human lives as possible be a goal worth striving for? If every human life has intrinsic (not to mention economic and cultural) value, then declining reproductive rates are a form of opportunity cost, not "one of the most important ... achievements in human history." And if we can't agree (or at least agree to act as if) every human life has intrinsic value, we're on our way to undermining the foundations of peaceful coexistence.
Where are you getting those numbers from?

My understanding is that there's a nominal fee for last-mile delivery the USPS charges mail from other countries, which is all (or the vast majority) that's being charged for Chinese shipments, as the Chinese side is subsidized completely (or almost so) for outgoing mail. I think the $2 you are quoting might be the treaty fee for delivering mail from other countries, which is not the true cost of delivery, but mostly works out as long as there's a fairly even flow of mail between two countries. What we have here is that China is subsidizing their side of the outgoing mail, so all that's being paid is the treaty set delivery fee for external mail (which again, isn't the true cost of last-mile delivery).
Apple NPCs will defend this.

It was an interesting time - Java didn't have generics yet and C# didn't exist. OO purists were complaining about C++ and Java implementing subclassing using subtyping but in the end no language really directly supports something like the Liskov substitution principle, which is about behavior and not just substituting function signatures.
Well, I have a T480. Here are the issues:

---

fingerprint reader: unsupported, driver under development

smartcard reader: unsupported

infrared webcam: half works with V4L, flickers or appears green at full resolution due to odd pixel format (fully working if you write your own image processing)

Live switching between discrete NVidia GPU and integrated Intel GPU: distro-dependent

Other than that, as far as I can recall, everything works perfectly, and did so out of the box. The main thing that annoys me about Linux these days is a lack of vendor-supplied binary packages, meaning I have to either compile from source or rely on a package manager. But if you use an Ubuntu LTS release even that is mostly a non-issue.
I think this article should be retitled to remove the word "How" at the beginning, since it doesn't even really speculate how one would go about doing this. It's interesting nonetheless.

Any ideas? Assume that someone decided to harness one of the many click-farms to do automated podcast subscriptions?

I suppose it's also possible that Apple did an ill-advised algorithm change or something that changed the weights very heavily, and the spammers who had been quietly doing their thing for months suddenly all got promoted.
The motivation for me to switch in 2007 was living the virus nightmare on Windows, time machine backups and access to really great photo management and video editing software preinstalled given I’d just had kids.

My most recent Mac was a 27” 5k when 4K monitors were on the cusp of being a thing, given the whole Mac was the same price as a high end 4K monitor - just the monitor - at the time. Love fusion drives as well.

Those were contingent on the times though. Nowadays there are decent software options on Windows, backups are still a pain but there are decent cloud options, I don’t know. Up to now the Mac has given me things you couldn’t really get on Windows. If that’s not the case when my current max expires I might consider Windows again but it would be a wrench to go back.
I'm in Canada and I can still order all the $.99 items with free shipping from China I want - either there's some sort of magic happening, or the renegotiated terms still allow substantial subsidies.

We just went through this cycle - ultimately we build packages (debs) and dockers, for deployment within VMs. Our build process - depending on the component pushes the deb to repos, or uses the deb in the docker.

After trying to replace pip with Pipenv, we had to stop. The dependency resolution time for 20 declared dependencies (that in turn pull down > 100 components) takes well over 5 minutes. With poetry - it takes less than 33 seconds on a clean system. The times are consistent for both Ubuntu 16.04 and Mac OS X.

Our only goal is to get to the point we're now in - tracking dependencies, and separate dev requirements (like ipython and pdbpp) from our other requirements. Poetry made it fast, simple, and made me an addict.

Over two days, I moved our entire codebase and every single (active) personal project I had to poetry. I don't regret it :)

While Apple doesn't comment on how the rankings are calculated, the common knowledge is indeed that its heavily biased towards recent subscriptions.

For me it's perfect: you get a three-character penalty to remind you that you're sacrificing your privacy for convenience. Up-front cost. I do the same with social apps on my phone, I put them far off right on the dashboard, in a folder. That way, it's a little bit annoying. Just a little.
In a feudal system the money flows up and the protection flows down - look at Putin and his oligarchs. In the US it's only the money that flows upwards.

> the Fed injects money into the economy

It's deceptive to conflate the Fed's response to the 2008 financial crisis with normal non-crisis operations.

It's true that the Fed purchased a lot of securities in response to the crisis.

You can see their balance sheet ballooning from $0.9T to $4.5T here --> https://imgur.com/a/PGthKNj

When the Fed buys securities, they essentially create new money out of thin air. So that's $3.6T of new money.

But that program ended four years ago. Since then the Fed's balance sheet has been gradually shrinking.

Since the program ended, the Fed has sold $0.4T of those securities.

Just like the Fed creates new money when they buy securities, they destroy money when they sell securities.

So for the last four years, the Fed has been destroying money, not creating it.

This has nothing to do with the national debt, or the government selling bonds to finance the budget deficit.

With the exception of the Fed's crisis response (which ended four years ago), the bonds that fund the national debt are held by the general public and as foreign reserves by nations around the world -- not by the Fed creating money.
I'd argue that things like "likes" have created an environment where people generally publish what they think other people would want them to say (e.g. things that will be "rewarded" with internet points), rather than what they actually want to say.

I think a lot of these articles miss an important consideration. The underlying economies of the world have functioned on an unseen assumption: the population (i.e. consumers & producers) always increase. This has been true for the entirety of modern history. There should be some discussion on how that changes once the population either stops increasing, or declines.

This is somewhat discussed with the aging baby boomer generation being larger than their childrens, but that dynamic will likely become the new norm in many countries. Japan in particular is experiencing this first hand with one of the lowest birth rates.

I'd like to hear about this as well. OpenBSD has been on my list of "to try" for quite awhile but the app/package thing has been a big question mark for me.

I _really_ enjoy being able to apt-get or brew install pretty much any of the applications out there and am a bit worried about how that experience would be on OpenBSD. I guess the best way to find out would be to try it eh? :)
Ask HN: Founders, how did you balance between increasing users and revenue?
Startup has limited resources. Hence, I found myself in catch-22 situation.

For example, if we want to increase revenue, we need more users. To increase users, we need to spend more. However we do not have enough revenues to justify the spending. How did you make decision(s) in this situation?
No mention of Anaconda?! How strange. I recommend using `conda` instead of virtualenv, and instead of pip where possible.

A Python project does not only depend on Python modules, but non-Python modules as well. Beyond Python, conda helps manage your other dependencies, like your database. I use Miniconda instead of Anaconda, to avoid the initial mega-download.
Choosing to not change a setting is still a choice.
I would not advise eating foods containing iron bolts, though. This is what happens with the microplastics, they're everywhere now.
While it's unlikely that money saved would be directed to more useful endeavors internally, as a US citizen I'd prefer that money not subsidize Chinese commerce (or rather, subsidize US consumers purchasing directly from China).
OTOH, all those chemicals are problematic precisely because they leach out into water. So you might expect marine microplastics to contain little-to-none EA chemicals, as they've been "cleaned" by the ocean for a long time.

Presumably they would still be allowed to work for a company that does not compete with the one they worked at previously, so they would get those 50% on top of the salary of their new job.
I've wondered what would happen if Apple acquired DuckDuckGo.

In theory, Apple could overpay a lot and still make a ridiculous return by using it as their default search engine. The usage would multiply overnight.

It would also reinforce Apple's position on privacy, and make Apple less dependent on Google for revenue.
Please don't take offense, but these subsidies are paid for by our taxes and I have no interest in paying to help you dress nice.

Also, if you're really buying clothes from China for $1-$5 you're almost certainly supporting child labor.

This is how it used to be done in parts of Cheshire, which had the interesting effect of leaving large voids under parts of some towns and consequent subsidence. The solution was to effectively underpin whole areas by pumping in massive quantities of grout (a £28m job in y2k) whilst simultaneously pumping out the brine.
“He who knows he is a fool is not the biggest fool; he who knows he is confused is not in the worst confusion. The man in the worst confusion will end his life without ever getting straightened out; the biggest fool will end his life without ever seeing the light. If three men are traveling along and one is confused, they will still get where they are going - because confusion is in the minority. But if two of them are confused, then they can walk until they are exhausted and never get anywhere - because confusion is in the majority.”

Delaying Brain Injury
Thanks for posting comments. My Technique is based on 25 years of research in the aging medical archives in the many libraries in Philadelphia.

My initial research was started because I read of a cold water drowning victim who was recovered and revived with no brain damage after 40 minutes of submersion. Could what delayed anoxic brain injury in him be applied to victims of Sudden Cardiac Arrest?

Encouraged by my early research findings (through teletype and microfiche) I was driven by my own intellectual curiosity to find out why people of cold water drownings had no Hypoxic Ischemic brain injury.

With my research papers in one hand and a medical dictionary in the other, the results I discovered are shown on the website of the Brain Injury Foundation (.org) Jeffrey Dobkin

Relevant quote from the article:

“The process of withdrawing from the treaty takes at least a year and the White House said it would be willing to remain in the UPU if negotiations were successful.”

The UPU has not reclassified China despite years of pressure to do so, and this is the only leverage left to a country in the treaty to force that to happen.
