I suspect the idea was partly that we already have to build infrastructure for roads; why not make the roads also a source of power?

In practice it will take many iterations to reach a point where it makes sense. Or it simply may never make sense.

The recent articles about some California farmlands being converted to solar fields does make sense. They were running out of water, but they had a lot of land to use for something.

Even if solar roads can work, there's still the problem of relatively inefficient tranfer of power over long distances. It makes little sense to spend a lot of money to make a solar road that's far away from energy consumers since a lot of the energy produced by the road will be lost in transit.
“They taste absolutely terrible”

That’s your opinion, I personally think it tastes great and haven’t had issues drinking it over the past 4 years. Given that Soylent has continues to grow signals that other consumers agree (investors also agree given they’ve raised $50m led google ventures).

Also your product costs $12 per 500 cal (vs. $2.42 for 400cal for soylent) which is a huge selling point for people that drink soylent (it’s affordable, convenient and better than most fast food alternative)

私はネイティブの日本語話者です。確かに777個の漢字を知ると90%をカバーできるとは思いますが、それがイコール日本語の90%をマスターしたとは言えないはずです。実際、この文章は極めて平易ですが、外国人にはそれなりの難易度になっていて読むのに非常に苦労するんじゃないかなと思います。
それから、リストのすべてをレビューしましたが、一部「経（ふ）」や「格別空」は言葉としておかしいです。また「恬然」や「整復」は明らかに頻出語句ではなく、ソースに偏りが見られます。

I'm a native Japanese speaker. I agree that 777 kanjis are contained in common sentences at the rate of 90%, but it doesn't mean you can complete 90% of Japanese. Actually, these sentences are very easy to read for Japanese people, although it's hard for foreigners because of the difference of vocabulary.
I also reviewed the list. I believe「経（ふ）」and「格別空」are odd as a word. In addition, 「恬然」and「整復」 are not frequently appeared so I think there was a bias to choose sources.
The book’s use of the term “architecture” is pretty different from modern usage. It refers to the shape that the new computer/OS will present to application developers. The architect is something like a product manager; a voice for what the customer wants.

What my team calls “architecture” - the decomposition into services and classes, database schemas, interfaces between major components - I think Brooks would call “implementation design.”

One year before Fukushima:

> Computed risks for new reactors are lower than for current designs "when only internal events are considered," according to a 2009 report that the Nuclear Energy Institute wrote for the NRC. (That includes fires or pipe breaks, for example.) But when risks of damage caused by external events — earthquakes, for example — are factored in, the new reactors are no safer than older reactors. In addition, because utilities have no operating experience with the new reactors, the probable risk assessments are purely theoretical and not as reliable as years of actual operating data from existing plants.

> The new designs are engineered only to withstand a predictable sequence of events, something engineers theorize may happen. In nuclear parlance that is called a "design basis accident." The new reactors, like their older counterparts, are not designed to survive an unexpected sequence of events. That is the critical flaw, says Lyman: "Three Mile Island was a beyond-design-basis accident."

That's a rather naive point of view. Yes free press as an ideal is great, but that rests on the premise that press' goal is for the betterment of the country. But in reality, press is effectively weaponized as a propaganda tool that's trying tirelessly to push their own agenda. I think of limited press freedom in China as a measure of protectionism, it knows it does not have the level of sophistication when it comes to pushing out their own narrative, so it blocks it off. And I have no doubt that there will be free press when the parity in sophistication is reached.

Most solar panels are very inefficient at converting the sun to electricity so they need all the help they can get. Two things solar panels require is to be clean and to be perpendicular to the sun. A solar road achieves neither of those things.
Give it time. Compulsory Latin education was very common for a very long time in large parts of Europe. In parts because the catholic church had a lot of influence. Now people barely even remember it. Many schools now offer Latin as an elective subject, and those who are into that sort of thing can study it to their hears contents, without wasting everyone else's time [1].

Something similar will probably happen to Kanji. They'll become more and more useless. And, eventually, education will adapt. Give it another generation or so.

[1] I realize that whether or not studying Latin (or Kanji) is a waste of time is a contentious point. If it's your cup of tea, go for it, but don't force it on others. Force them to learn maths instead.
> Think they’ll retract the S-1 and stay private?

And get their next cash infusion from where, exactly? If they manage to find even more private investors, that might be an option, but would probably hurt their image more than the negative press around the S-1.

The current system was ripe for a fantastical display of absurdity, and maybe this is it. It's startingly familiar given the current US political situation.

Couldn't you phrase a strategy as a time series of binary decisions, e.g., of the type "buy/sell stock X at current time: yes or no"?

Then the inverse would be obvious. However, it's not immediately clear to me whether the claim holds that an inverse thus defined would perform better than the original strategy.
And the craziest thing is that the sunniest parts of the planet are completely uninhabited, so land is plentiful and cheap. As opposed to urban areas, which are the most expensive real estate that exists.
>After her video was posted online, she told us, “I had to change my major and career choice. I lost a lot of friends, and my family wouldn’t talk to me for a while.

It was one of the worst things I have ever done and not just because it showed up on the Internet. I wish I could erase that memory out of my mind forever.

Fuck having responsibility for your actions.
Thank you for humoring me. I had to sleep on it, but I can see it now. Seems like it would require a really bad design or more likely bad actors (remotes leaving dead sockets open), but it would definitely be possible.

The same scenarios would lead to resource exhaustion if the thread pool wasn't bounded.
I'm curious about the no-triggers claim. There's stuff that happens after installing packages sometimes, which you can't put into an image. For example refreshing the font cache. How does that work here?
Really cool project. Nice work!
I think putting a roof on streets (on a relatively light aluminium/carbon fiber scaffold) for the panels is less outlandish than trying to fix "solar roads" by adding maintenance vehicles (or solar roads themselves, really).

It keeps away rain (which improves driving), doesn't expose the panels to the weight of tractors, has similar safety properties (the panels need to react quickly on any accident related impact and isolate affected circuits to avoid electrocuting passengers), and if slanted, is somewhat self-cleaning in wind or rain.

I agree though that it's nice that somebody did a field test. That idea sprang up again and again and it helps to have some real world data: people anticipated the cracking issue, but who argued against solar roads because of leaves killing the efficiency?
So after my erroneous comment, i have learned that roofs, parking lots and bike lanes are better candidates. I just dint want to give up on converting asphalt to energy generators.
...and this is how we end up with people driving through fire trucks. I haven't sat in the 3, but I did drive Model S and also played with the e-Tron's controls while waiting for an oil change (which ids pretty much the only advantage of an electric car I could possibly think of). Controlsd in both are very "neat". As long as you are sitting on a showroom floor. The very thought of actually trying to live with either while driving makes me pine for my very first car, a rusted through Chevy Citation that I paid $300 for.

Just because it is a good selling point for a certain subset of population that likes new and shiny and does not mind mowing people over in the process does not make it a good thing.

Starbucks also has incredible gross margins of close to 60%. Almost as high as a SaaS business (70-95%).

WeWork has 10-15% gross margins.

"Gross margin is a company's net sales revenue minus its cost of goods sold (COGS). The gross margin represents the amount of sales revenue that the company retains after incurring the direct costs associated with producing the goods and services it sells."
Everyone is their own worst critic. I frequently am editing production code I wrote 15+ years ago. I also have to deal with the unintended consequences or side effects from my code that were not thought out at the time. It certainly is hard to teach this kind of thing and, more importantly, find a way to get people who haven’t experienced it to find the value in doing so.
The frustrating thing was that pretty every problem that arose during these trials were already known. Those who spoke up were ridiculed for being naysayers. There's a balance between those who reflexively oppose everything and those who have an informed opinion based on experience and knowledge. There was quite a bit of overlap between those who strongly supported solar roadways and the "I f*ing love science!" crowd that have turned science into something indistinguishable from magic.

The original installation in Idaho ran into predictable problems almost immediately. The much larger installations had very little justification for going forward other than it was very popular with a rather vocal group of voters. Doubt any of the politicians, celebrities, or their fans who pushed this and dumped all over those with credible objections will apologize for their part in the boondoggle.
Alone in the Dark was very similar to an H.P. Lovecraft story and if that was what you were looking for that is what you would find. Relentless Twinsen’s Adventure was an intense fever dream of a fantasy that kept the player going on pure suspense and wonder. It had the dramatic finesse of Loom or a good sci-fi novel. When I purchased it I had only assumed it to be mindless entertainment. It turned out to be a statement on the human condition that was too valuable to let everyone know about. I diligently played it after school for many days giving the game my full attention. When I was finished I felt like I grew up a little and society at large did not let me down concerning the harsh truths revealed in this game. This is why I’ll never forget Relentless- the general malaise and apathy of the time in history it was released deeply contrasted against the wake-up call contained within the lessons of its gameplay. Both games we’re ahead of their time and technically very impressive.

> I don't even know how China got in the WTO in the first place

The hypothesis was a wealthier China would become a freer, safer and more democratic and stable one. Ceteris paribus I still subscribe to that view. But the effect of modern technology on the scaling capacity of dictatorships was unexpected, among other things.
I think it'd be much better putting panels over roads. It uses pretty much the same footprint and it'll reduce the effect of roads being huge heat sinks they are.
> Maybe expectations need to be adjusted, but experiments like this are worth doing!

No they are not. Solar roads do not make sense, not for a looooong time anyway.

So far, all of the currently failed solar road projects have failed in utterly predictable ways[1][2][3], and I'm certain nothing novel has been learned.

There are so many better places to put solar panels than beneath roads. If anything they should put water pipes to utilize the heat. But solar panels, that's like trying to optimize a function for another 0.03% speed while there's still order of magnitudes of trivial improvements laying on the table elsewhere.

Awesome. Always ask for a call back number. My dad was in his late 70s and fell for stuff like this. I beat the notion into his head, if in doubt ask for a call back number. If they they refuse to give it, it is a scam....period.

5) zkanji: https://github.com/z1dev/zkanji! It's got a dictionary from which you can directly add words into its study decks when looking them up, and it has handwriting recognition plus let's you easily find similar looking kanji (with shared components etc), which is great when tesseract ocr fails, or when the text is so blurry/compressed you can't really even see it clearly (the online Japanese war history archives really love to compress their scans).
So ... this is more or less exactly how Haiku's package management system works. (It was designed in ~2008-2009, merged into the nightlies in 2013, and of course has been used by default since then.)

We use different terminology for a number of these things, but all the concepts are almost identical. Is this really the case of two completely separate creations of the same idea? Or is this another instance of the Linux world NIH'ing something a different project had for a while without even mentioning it?
A majority of shortwave stations are engaged in propaganda of some form or another, beaming a message across international borders. The US has multiple operations covering the Middle East, Asia, the CIS and Central America, most of which were historically funded and controlled by the CIA.

https://en.wikipedia.org/wiki/Radio_Free_Europe/Radio_Libert...

https://en.wikipedia.org/wiki/Radio_Free_Asia

>The station now uses more than 100 radio antennas located in countries all around China, such as Thailand and Taiwan, which trade the signal — in effect, playing a game of keepaway with the station’s broadcasting.

Shortwave broadcasters change transmitter sites and frequencies throughout the day as a matter of routine, because the atmospheric conditions that allow shortwave signals to travel beyond the horizon are constantly changing. Most modern shortwave transmitters are steerable and frequency-agile, so they can be reconfigured in a matter of seconds to provide the optimal coverage of the target area. Efforts to evade jamming are really just an extension of the normal operation of a shortwave station.

https://en.wikipedia.org/wiki/Skywave

https://en.wikipedia.org/wiki/ALLISS

It's surprisingly difficult to jam a shortwave station within your own borders due to a phenomenon called beam skip - at typical frequencies, there's a large gap between the line-of-sight coverage area of a transmitter and the longer-range signals that bounce off the atmosphere. It's just about viable for a country the size of China, but it would require multiple overlapping transmitter sites and would be unlikely to provide consistent jamming.

"It was his response to a dearth of Chinese-language news coverage that wasn’t heavily influenced by the Chinese government." So maybe because AP/Reuters/etc. are biased?

It also seems from browsing their site that most articles are summaries/commentaries of other sources.
It's a fundamentally stupid idea. Passing solar light requires transparency. Transparent materials (glass, plastics) wear quickly and make terrible road surfaces. Texturing the surface to make it a better road reduces transparency and increases wear even more.

How about solar (covered) parking lots, solar roofs, etc. It makes far, far, far, far more sense.
That sounds intuitive but does not follow. The strength of the random strategy is that it approximates the theoretical ideal - a maximally diversified market-cap weighted portfolio. The non-random strategy is too concentrated, and inverting that can leave you with another strategy that is also too concentrated compared to the ideal.

The problem isn't that the non-random strategy did poorly, it's that it has too much exposure to needless sources of uncertainty. The inverse strategy doesn't get rid of uncertainty, it just flips the sign of their exposure to that uncertainty.
API and system design is usually technique agnostic - but I think the biggest reason to have someone designing the system close to those doing the work is both motivation and buy in. As people get more senior they tend to code less frequently, but that’s usually okay - a doc describing all aspects of a system is very much a coding exercise.
Jesus THAT'S your reaction??

You're trash.
Indeed, I like working when it serves some purpose. I don't mind some idle periods (recovery, thinking, travel and experiencing).

The challenge comes when we put our energy into work in places where our output is squandered. For a great example, imagine the game developers who built entire AAA games, only to see their games canceled just before release. Yes there may be many reasons for the cancellation, but the feeling of wasted time and creativity is real.

Manual labor is practical, and it can be useful and even meditative. Unfortunately, it usually doesn't pay enough to live in most modern areas of the world.

I don't know the age of your friends, but I would posit that they bounce around because they have a strong sense of "this is not right" when they get into a job. I have had more satisfaction from some of my days waiting tables (providing a really good dining experience!) when I was young, and I have had some soul-crushing days sitting in futile meetings about projects that were doomed from the start at big companies. If you asked me during those meetings, I would have rather been a waiter making $3/hr + tips. At least then I would be making people happy.
They also didn't think about the pressure and weight from tractors

I mean, the hell? I wouldn't put solar panels in a playground, because I would assume 50 pound children running around would destroy them. Obviously, motor vehicles will. And very quickly.

Is this some sort of insane joke?
Microsoft Has First Major Impact on Chrome
Oh god I'm getting flashbacks.. people saying 'think of me as an "urban planner" rather than an architect'...
Think the person you responded to meant for the solar panels to be above the parking lot, not the parking lot surface. IIRC, Google has quite a far solar panels in their parking lots, where they not only generate electricity but also provide shade for the cars parked there. I've also seen a couple of rather massive solar panels in central Atlanta near CNN. I was told they were installed by Ted Turner because he has a penthouse nearby. No idea how much power they generate but it does provide some nice shade.
Bullshit. Good software is never mature, it evolves over time. A good software architect, or ideally any dev should be a good software architect, will make sure it stays on course to: little tech debt and doesn't become toxic.
Why would this even be tried? It's an obviously terrible idea for lots of reasons.
I agree that we as a society generally need to afford ourselves to be brave and fail sometimes. But... this seems like such a bad idea even in theory.

Road surfaces have pretty specific and harsh needs, which currently can be mostly solved with really cheap solutions (concrete/asphalt). Photovoltaic cells on the other hand are comparably very expensive and fragile.

Surely, land can't be that expensive in most places that it makes sense to use the road surface, compared to say roofs.
"The engineers also didn't take into account the effects of leaves, which caused damage and limited the amount of electricity the panels could produce. They also didn't think about the pressure and weight from tractors, two locals told Le Monde."

They were warned about this.
I think it ultimately depends on the circle of people and what kind of cuisine they have normally. I think Soylent tastes quite mediocre- but my favorite foods are curries and vinegar/chili oil sauces. (Sad to say I often have meal replacements as punishment food.)

I would definitely try this saag as a service(alas, I live in NYC), as a healthy alternative to food I already love eating. Meal replacements are definitely not covering that niche for me.
Can't get more niche than this! But it's great. If I lived in SF, I would try it.
I remember at the time this was announced, I was working at a startup in the solar PV industry. Our collective response on the workfloor was, "wow, that's an incredibly stupid idea for so many reasons". Surprised it took them so long to admit failure.
I can't imagine how hard it must have been, in France of all places, to try something that bold and risky and obvious to oppose beforehand.

We're the country of ruthless self deprecation coupled with perfectionist universalism.

I hope something was learnt here (other than learning not to do it again), and I'm absolutely confident the people who cluelessly pushed for it will go on their public careers unaffected while the innocents are punished.

We've done more insane stuff and survived to tell the tale.

But really, PV in Normandy ? Come oooooon....
