Surprisingly never heard of Thermophotovoltaics.

Here's a simple diagram https://proxy.duckduckgo.com/iu/?u=http%3A%2F%2Fanilyuksel.f...

It seems like 'impedance matched' photovoltaics.. very interesting.
Can you explain more about this? What does putting your daughter to bed look like??

It sounds crazy!
I suspect the permafrost melt has an important detail that some people are forgetting: Methane has a short half-life (7 years) in the atmosphere though it eventually turns into CO2

This (I think) could cause an overshoot, then a reduction of the total greenhouse effect
"He was a great galumphing racist."

Well, gosh golly and gee willickers! That old rascal!

I don't think anyone benefits from this sort of white-washing the past. How about taking the topic seriously and writing, "Sadly, he was an unrepentant racist who literally bought or kidnapped his 'performers' before exploiting their racial differences or physical deformities. This was not a good man."

Honestly, I stopped reading after that. I have no desire to read some revisionist history puff piece about such a horrible human being.
You should take a look at the trim package and how often hat is downloaded.
A good way to get Clojure into your contracting work is with polyglot solutions where Clojure, along with, say, Python sits behind a Node.js gateway. Combined in this way Clojure is always accompanied by 2 of the most popular languages - Javascript and Python.
Is this supposed to sound bad or good? Well, 3m² to make toast intuitively sounds bad I guess. Well, consider this: It's enough to run 2 small office PCs with all peripherals. Considering that it sounds much more positive. Really just anything producing heat would sound bad because of power dissipation. A toaster is probably one of the most extreme ... (Imagine putting 1kW into a slice of bread without power dissipation!)
Sometimes it's about being professional, but more often than not it is about taking and ignoring mountains of problems.
You get called for being a whiner if you constructively point out problems, and a problem case of you try any solutions that are smarter than whatever your middle manager(s) comes up with.
Worse, if they perceive you as a threat. Or fail to play office politics - you will be that guy who does most of the work, or hardest work with no renumeration. Favorite of all hiring teams until inevitably getting psychologically damaged if you're normal in any way. (Especially crude way is to give someone a problem insoluble by one person or overload a small team.)
I'm using Lispworks. Good IDE, solid and CAPI is a great for development of IDE and graphics. Start using the free personal version and if you like it, get in touch with them, they will help you. I also like SBCL+Emacs+slime+org-mode.
I honestly was not aware you can burn plastic with minimum air pollution. Where I live, many people warm their homes in winter by burning plastic junk they find on the street. I don't have to explain what sort of air it produces. Being in it feels like washing your face with sulfuric acid.

After living under these conditions for many years, it'll be hard to let go of stereotypes.
details of my direct upstream peers would be here: https://bgp.he.net/AS204994. Some of my peers (CLoudflare, he.net) are peering directly over IXes (KleyRex, for example) and some (Google) would be though the route server...
> concern then falls off to zero as you approach closer to the dam! That is, the people living immediately under the dam, the ones most certain to be drowned in a dam burst, profess unconcern.

It's a fun story but it doesn't prove causality. Maybe their faith in the dam is why they moved there.
And Teslas can use non-Tesla charging networks. Tesla should standardize on CCS plugs where it makes sense to (like they've done in Europe) and open their chargers up to other EVs.

Tesla was recently denied a government subsidy in New York because they're not offering CCS charging, which is fair enough. If they're not going to make it available to all EVs then the utility of the infrastructure is limited and they shouldn't get any discounts funded with public money:

I'm curious why you feel its the Catholic church specifically. My understanding is that strong disapproval of gay or trans people is common throughout the Abrahamic religions.
Interesting article on media business model. never really considered the change from print to media content as much because I grew up with media print my primary source of information which made this to be very eye opening.
5-Axis Machining: The Game Changer in Manufacturing
I think what is driving the distinction between what the author is claiming and what WashPo is talking about is that whilst it's true the data suggests people gernerally over-estimate their ability relative to others when they under perform, that's not important. It's not important that the average guy thinks he's smarter than 60% of other people. The important bit is that the idiot thinks he's smarter than average.

So there's the DK effect, and there's the interesting part of the DK effect.

But in the original article, the line is drawn to Trump. But I don't think taking a statistical pattern and then applying it to the public persona of a reality TV star is a good idea. If we're going to object to anything, I'll object to that first.

I've been looking for information on risk, overall, by passenger miles travelled, by trips, and by time-in-mode (which adjusts for typical trip length).

Only partially successful, though I find:

30,690 overall auto fatalities.

- 6,067 cycling & edestrial fatalities, combined.

- "More than 90% of pedestrian fatalities occurred when the victims were hit by automobiles and light trucks."

- "A related study on risk factors for on-road cycling commuters indicated that prior to car-bicycle accidents, 89% of cyclists were traveled in a safe and legal manner. In addition, vehicle drivers were at fault in 87% of the events."

The risk externalities of motorised vs nonmotorised transport appear far greater.
They should have made a way for simple web-components to declared and defined without any Javascript. Simple static HTML.
It might help to add the ASK HN, frame it as a question, and provide context.

For example, what's the market, product, buyer persona?
I'm sure people are, but it's too big of a problem to fit in the space of thinking for the average person. Also, where do you live? If you don't live in any of the areas soon or already being affected (e.g. Pakistan, India) then it's not an 'immediate' (relatively) concern. Of Europe heats up, it's still cooler than Mumbai.
On Deep Work, Cal Newport recalls how Carl Jung built the Bollinger Tower to be away from his daily obligations in Zurich in order to produce high level work. It shouldn't come as a surprise that Melville would do the same.

By the way, for those of you interested in Deep Work, I've put together some notes here: http://alvaroduran.com/deep-work. Any feedback is much appreciated
Now do the same for the devil:

"The devil, by definition, is that for which no greater evil can be conceived. The devil exists in the understanding. If the devil exists in the understanding, we could imagine him to be greater by existing in reality. Therefore, the devil must exist."

From which it also follows that:

"If the devil doesn't destroy god, we could imagine him to be a greater evil by destroying god. Therefore, the devil must have destroyed god."

At which point we must conclude that it is a shame that theology has captured the minds of so many brilliant people.
The paper was published 18 July 2018. The public inital commit of libra was on 18 June 2019 and had 1,063 changed files. That could be a coincidence or not. Fact is, only one has realized the idea.
Methods seem to vary a lot by country, and some of the highest-rate countries don't primarily use guns, so I'm not sure other methods can be easily dismissed as less dangerous. For example, Belgium's overall suicide rate is higher than the USA's, and the most popular method there is hanging (a majority of male suicides, and a plurality of female suicides) [1]. Of course I can't say that the rate wouldn't be even higher if Belgium had more guns, but it manages a quite high rate without them.

> you do get exposed to a fair amount of Java stuff

Can you please expand on this? I've been using Clojure as my main PL for the past 3 years, and honestly only once I had to actually deal with some Java code (when I needed to figure out some Selenium stuff).
Url changed from https://phys.org/news/2019-07-heatwave-human-body-thermal-li..., which points to this.
We already have drones with wings that are capable of that, or close to it. This would make them more efficient.

For quadcopters and similar I doubt it will be enough.
The article talks about “wet bulb” temperature. That takes into account humidity. When the temperature is at or above body temperature our body relies on evaporation to cool.

The problem for many areas is it’s not a dry heat. I like many other people as you point out have lived in 35c and above areas just fine, but the humidity was very low - it wasn’t really that bad if you could avoid direct sun exposure and didn’t physically exert yourself much.

Once that humidity creeps up then it’s a problem.
The blogpost says that == is needed while the paper doesn't.

I'd say having == is more performant for strings.
Being "Green" was always about Reducing first and foremost, which is what would happen collectively under a carbon tax scheme.
It's just apathy, and the difficulty of perceiving how it can impact any of the 'people' the individual level.

Every person feels like, often rightly so, that they have enough fiscal and social stress that immediately impacts their lives.

For an (U.S) example, Presidential elections: the results of which undoubtedly impact the entire nations population in, potentially, massive ways in every sphere (social, economic ect.). You cannot really escape it either, it permeates news cycles at all levels nationally and globally.

Since 2000 it turnouts have been bounced between 50-60%. Given that, how many people are really going to be concerning themselves with something like climate change? Tax policy rattles more people than climate change ever will, they may even recognize it themselves, and yet people just don't care (or have more immediate concerns).

If you want someone to care, they have to be moved enough by being directly impacted. In climate change's case, it will be too late to do anything. But that's just how people (including myself) work.
If you ever need someone to talk to, the national suicide hotline is 800-273-8255. It’s free and open 24x7.

As someone who struggle(s|d) with ideation, I realized that I too was on that path. If I kept idealizing suicide then I’d eventually succumb. Some recommendations:

1. Find a therapist with whom you can build a relationship.

2. Be open to medication. Even if side effects can hurt your quality of life, you’re clearly already suffering from QoL problems.

3. Keep an emotional journal. In it, also track common culprits like sleep, food, alcohol, etc. this can help you identify and avoid triggers.

4. Strongly consider active exercises to change your outlook. Force yourself to have a social life and hobbies. Cognitive behavioral therapy also has a number of (sometimes touchy-feels, yet effective) exercises. You can learn more from the book “Feeling Good”
It's not suggesting that European temperatures are problematic, other than the observation that despite the recent much discussed heatwaves, Europe has it relatively easy compared to many other parts of the world. It is suggesting it's becoming problematic, and near thermal limit for Southwest Asia, and will likely become so in the Persian Gulf, South Asia, and the North China Plains in the near future.

Where is the alarmism?
That is talking about heat and power cogeneration, not solar power if that's what you're thinking. The paper they site [0] says the density can 300-400kW/m^2 and so at 300kW, 50% efficiency and a small C5 envelope you're looking at over 5kW.

conda use namespaces (called channels). If you want a package from a random person, you've to explicitly add it (either globally or when installing the package).
1. Company builds a product with no/minimal ads and uses community involvement to grow.

2. Company adds more ads to the system to earn money.

3. Company adds more "features" to make money (for expenses and...to make money).

4. Company reduces consulting with the community because the purpose of the community, to grow the site and userbase, has been served well and the community's interests conflict, at times, with the company's commercial interests and directions.

5. Community complains that this is not good.

What would people expect after this? That the company would have a change of heart and go back to how it was years ago? I don't think that's easily possible nor desirable by the company. I'd expect that responses, or the lack of appropriate responses, would be to have those who are unhappy to leave.
This might be off topic but why does the Australian media constantly source their "expert" quotes from the Institute of Public Affairs? The entire organisation is complete bullshit. Surely they can find people with actual credibility to put up an opposing argument once in a while.
It's not as though this issue only affects the US:

"Between January and October 2018, Germany exported 114,000 tons of plastic rubbish to Malaysia, an increase of 125 percent"

"Germans are great at separating their household waste, and the country is not allowed to export plastic unless it's for recycling. So why are there piles of German garbage all over Malaysia?"

I'd be interested to read any research on how drugs impact suicide rates (particularly if it prevents people who would have otherwise committed suicide). As easy it is to get guns, I think drugs actually a bit easier to obtain despite being the thing that's illegal (due to gun purchase wait period).
Start with problems that have a large enough market, understand the issues, find a solution and package it as a product.

If the problem is big enough, and the solution solves the pains, then the demand will be there.
The article is not about solar cells though. It's about thermophotovoltalics, where you'd use a high temperature heat source.
Eons ago as an embedded programmer I came to respect Forth. I encountered numerous situations where using Forth led to a much smaller footprint (size in particular) -- Why? For exactly the reasons that Chuck Moore espouses here; you are writing a purpose-built VM from the hardware up.

Even then I don't agree that portability/abstraction isn't important - it's got the potential to be an extremely reductionist position. Instead I'd argue it's incredibly expensive and should be treated as such.
dice = plural

die = singular
Yes, the original article is about thermophotovoltaics.

Regarding the article posted here (and since a drone with a furnace is not feasible) I went with solar.
lmfao you can't make this shit up
> The C++ compiler needs to provide robust compile-time and run-time checks to tell programmers that things are wrong, like: “your operator does not meet the requirements of the sort algorithm”.

MSVC does that in debug mode - it will assert if you use an invalid comparator for e.g. map / set. No reason it couldn't be further improved, or a clang-tidy check written for that.
The software side of it has not helped. I blame the state of frontend web development rather than databases, payment gateways and other backend aspects.

Not every mom and pop store has a six figure sum to throw to an agency for them to spend six months under delivering a website for them with the 'latest agile methods'.

We sort of have ourselves to blame, the hubris and pathetic development approaches that go with ecommerce have killed the market for mom and pop ecommerce stores.

This is really bad for web development, the customer and the independent retailer.
Landfill it, it's harmless. And since it's only ash that messes up the salt, the mass is tiny compared to the input. Plastics produce virtually no ash.

Salt disposal could be a problem if it contains heavy metals, or if it contains something you want to recover (possibly phosphorus). Either way, MSO ended up concentrating the material in question and transforming it into a simpler chemical form, reducing the disposal problem, or making the recycling easier.
There's a coating bliss of social rhythm. When jobless I was 24/7 on collapse subjects. When working, I was busy doing my job, I was happy going there in the morning, seeing everybody doing their thing, eating and sleeping ready to go for the next day.
Yes, another vote for Hy. Just wish they had some more manpower to take it to 1.0. Be aware of "let" in Hy, though, as it's been removed from the core and now lives in contrib. "let" is a major part of any Lisp IMHO.
People seem to be misinterpreting this a lot.

This is not about solar cells. This is about thermophotovoltalics, and the application here is using a burning fuel source to generate electricity.

The "drone" the paper talks about seems to be a reference to another paper on unmanned sea vehicles though. Edit - to be fair the flying drone part is from the corresponding author.
The Catholic Church policy on condoms was blamed for the high rates of HIV in Africa and yet if you looked at the stats, the countries where protestantism was more predominant than Catholicism had higher rates and vice versa. Not claiming there was any causation there but the original allegation had no basis. If someone is going to flout church teaching on sex outside marriage they are hardly going to be worried about flouting it by using a condom.
Last week I alternated reading programming books and coding with jogging sessions. Every time I hit a mental block or just coding fatigue. I'd leave and run a bit. It wasn't super effective but overall it avoided stress and gave room for free mind wandering and new ideas.
It seems like a reasonable fix to this is to prevent name-specific owning (changing it to a group instead) -- this has the benefit that package maintainers who plan to maintain their packages forever can keep the same names, and those that don't can essentially fork their project and stop fixing the older version (@ <maintainer>/<project>) and force all changes to go to a new one (@ <group>/<project>) and hand off ownership as necessary.

This doesn't break old consumers and it allows for a pretty graceful migration path (if you want new updates, change your version) -- can eve be helped with marking package as deprecated or repo as archived and what not.
If this doesn't scare you I don't know what will. We have to do something about it. By 'we' I mean you and I. As someone said - if you don't think you can change the world you will just be one of the ones who didn't.

We need fundamental cultural and policy change. The question is how to achieve it. Despite popular believe I don't think voting matters. Think about any significant societal change in the last century or so. Women suffrage, civil rights movement, anti-war movement, gay rights. None of these were initiated by the parliament. They all started as a popular rebellion and direct action.

So what are we to do.

- Change your lifestyle. Less flying, driving, meat.

- Divest fossil

- Get out of the techno bubble and get your hands dirty with direct action and civil disobedience. e.g. [1]

POC for Message-Oriented-Middleware Based Architecture
Thanks, I will correct this in a subsequent version of the article.
F1 is a source of precise frequency and only an intermittent one. It puts a puff of cesium atoms into a state which is as controlled as is possible and then finds the microwave frequency that causes the largest number of atoms to change state. The second is currently defined as a multiple of the period of the microwave signal that, under specified conditions, induces that particular transition in cesium.

The up and down motion itself doesn't result in the time measurement.

The purpose of the 'thrown ball' in F1 is so that the atoms being measured are in freefall during their measurement which eliminates uncertanties in the measurement which would otherwise come from forces confining them and to keep them in that unperturbed state for as long as possible. By using a very long interaction (technically two interactions separated by a long time, a form of interferometery) the peak response can be made very narrow which allows for a more precise measurement.

F1's frequency is used to tune continuously running highly stable oscillators (or, really, measure their offsets so that they can be corrected in post-processing without being disturbed by frequent tuning).

The combination of a continuous stable oscillator and a counter gives you something you'd recognize as a clock. So you can think of F1 as a calibration process used to keep NIST's clocks on time.

This paper has a good technical overview of many of the considerations that go into such a device: https://tf.nist.gov/general/pdf/1404.pdf
Yes, well, if society deems it important enough, then we put safeguards in place which includes educating the installers about UV sensitivity. (you'd think the people who engineer these systems would understand the issue and put correct processes in place, no?)

I mean, yeah, if people don't care, negligence will happen because no one is watching. But people apparently care, in fact that why so many people are bothering sorting their refuse, because of their fear of landfills destroying the planet.
They get out of their deep hole very much on their own, usually within weeks or months. But that's actually the problem in bipolar disorder. They can go from total depression to a much more energetic state in days or a few weeks, such that suicidal ideation and feeling like shit can overlap with high motivational energy. And that's the most dangerous time for suicidal tendencies. In a very deep depressive episodes, suicide is just too much effort.

And yes, I was referring to Lithium as the only medication which significantly reduces the incidence of suicide attempts in bipolar patients. But that effect is only visible long-term.
From experience: you don't have to dig into the Java world for using Clojure any more than you have to dig into the C world for using a Unix shell.
> It still have a 35x potential growth, so it can "boom" again, but the EV industry now is huge

One of the hyped upsides of electric cars is decreased maintenance costs leading to a decrease in per-km capital costs of driving. If this is true, unless induced demand from this causes people to drive more, EVs effectively will shrink the total car industry pie, leaving something less than 35x potential growth.
The language around this is messy because not all depressive symptoms are shared, but I would say it's in how you view it.

In your example, being single and having a lot of debt can change over time. But if you were in the throes of a depressive episode, then you might believe absolutely that neither of them can ever change because they haven't changed yet/they'll take so long/it's impossible for you to expend the effort needed to change them/[...].

The facts are the same, but the conclusions you draw are different.
