Isn't large portion of the tracking aspect simple geometry and decrease in cross section are based on sin(angle)? No kind of concentrator can solve this limitation without also increasing dimensions and spacing requirements between panels. Are there any other significant effects causing decresase in solar energy conversion in addition to the losses caused by sin(angle) decrease in cross section area? Something like decrease in light to energy conversion efficiency when light density is bellow certain threshold or increased amount of reflected light based on angle ?

Overpopulation hits places like India and Bangladesh badly. China and Europe's population actually seems to be declining and they seem to be quite well off.

The original comment suggested to use CO2 captured from air for the storage facilities. Yet takes more energy to remove CO2 from the atmosphere than to remove it from exhaust. We'd be burning coal to extract CO2 from the air!
My father's parents were immigrants and they spoke their native language to each other, but they didn't want their kids to learn it. I've tested my father and he has about a 5000 word vocabulary, pretty good for someone whose parents didn't want him to learn it!

Kids have an incredible ability to learn languages, given motivation, and they don't need to go to school to learn words like "accountant" reading books will do.

Yeah, the answers in this thread clearly show that I greatly overestimated whatever pacifism commitment Lego ever had. I'm genuinely surprised, apparently they were quite successful at overselling the "play good" brand to me. Pirate cannons actually throwing plastic? Before today I was convinced that this was the defining difference between Lego and Playmobil.

I'm from the region that is home to playmobil and we have a joke here that by count of items identifiable as "handgun" we have the world's largest guns manufacturer at our doorsteps, given the number of pirate and wild west kits sold each year.
It obviously contains a lot of CGI, but the question is if the lego pieces are CGI.

Eugenicists, Hitler, and most recently, radical transpeople and radical feminists, etc all thought something similar as well. I don't think that's the right solution.

It all boils down to the old and dusty Nurture vs. Nature debate. And also competition; without competition there's no reason to live. If you pay close attention you'll realize that competition presents itself in different ways.
Correct.

History in an ideal world tries to record what happened.

But realistically, history is a tool for politics.

But judging by the heavy downvotes of your comment, that fact doesn’t seem to be popular.
On the other hand, changing the length of a varchar column in Postgres is actually changing the type of the table, and if you have any other objects in the database that are dependent upon that type (e.g. views), you'll have to drop and recreate them (and transitively, any views that depend upon those views) in the same transaction where you alter the column. This can easily spiral into a lot of work.
>and Europe's population

Where are you getting this from? Loads of countries are still rising in population, mostly due to immigration (birthrates of natives are below replacement rates).

>and they seem to be quite well off.

I wouldn't call Europe 'well off', unless your definition solely relies on "well, at least it is a developed country". We're facing multiple crises in several countries, and the younger generations are the ones most likely to pay the price.
It's so easy what you already support it :)

I'm pretty sure Singapore usings contractors to build the HDBs and doesn't employee labourers themselves.

But also Singapore's construction per sq ft isn't insanely cheaper than the US. You're looking at $120 per sq ft and you would expect Singapore to be much cheaper because they have $2-3/hr labourers, less labor laws, and far less environmental restrictions.

And the HDBs don't really house the poor but the middle class. The poor live in cramped dormitories for foreign immigrants.

Sauron was never bound by the oaths Istari took, and Saruman broke his, and those involved not intervening too much. Most of the time, Gandalf & other Wizards were running around trying to keep things together so that societies could rebuild.

The remaining higher technology groups either lost the capability (Gondor), were destroyed (Arnor), are fighting constant war with Orcs with occasional dragon making problems that prevents building up proper industry (Dwarves), or are depopulated depressed groups that while not hoarding, do not interact with others anymore much and mostly use what remains of their industrial base to facilitate the last days of their race (Elves outside of Mirkwood - those in turn are trying but don't have much to build upon since Moria got overrun and they lost their main trading partner for technology).

The rest is down to subsistence farming levels without base of previous knowledge to rebuild or at least inspire.
> It doesn't go up in smoke, it goes back into the economy.

There is still a gigantic opportunity cost of bringing together resources to produce an explosion rather then something more useful.

The old 'its going back into the economy' is some sneaky Keynsian language that only applies in certain macro economic situation and even that was mostly wrong and a misunderstanding of economic theory in the late 30s.

Wouldn’t that just cause a massive amount of confusion over what was legal cash and what exchange rates are? One of the economic strengths of the US is its unified currency which has been poorly copied by the euro.

A provably anonymous and untraceable digital currency backed by a government would see instant adoption. Before anyone complains about catching baddies just remember that serious criminals will astutely avoid any traceable currency or will find ways to launder it, only law abiding citizens and bunglers will be caught up in a surveillance state. The corrupt and criminal will remain as free as ever.
After almost a century of doubling down too much for too long it has become a societal character issue that can not even be questioned, let alone admitted. From Turk's point of view, Armenians asked for it when they worked together with foreign forces and rebelled, and all Turks did was to relocate them to safer locations so they don't get killed. If some Armenians ended up dead then it's because of problems related to transportation, lack of resources, etc, but definitely not a genocide, and even it if was, it's not intentional.

You can see the narcissist's prayer somewhere in there and it is sad that it has become (long ago) an easily noticeable character trait of average Mehmet. You can only move on as a society/nation if you looked back in your past and learned from your mistakes. Turks have been denied of this opportunity by a century of identity politics and now sadly it's too late.
The famous experiment seems to prove that a large number young people are bad for social stability in a mice society. That amounts to a pretty strong argument against infant healthcare /s.

I don't think we should generalize too much from mice to men. Deriving social policy from what works for mice seems like a very bold move to me.
Ask HN: Can a mutex have a race condition?
If two threads lock a mutex at the same time, wont both of them think they both hold the lock?

But then, if there’s a way to lock a mutex so that it’s impossible for two threads to do it at the same time, why not use that mechanism to modify whatever shared variable is in question?

I imagine that pthread or <insert other threading library>’s provided mutex is, internally, an integer which is set to 1 or 0 depending on the mutex’s state.

if i want to share an integer from my program with another thread, why cant I just use whatever is used by the mutex?

> 1300 guns

Ok? Is that a lot?

> were given to gangsters in Mexico by Holder and Obama.

There are two options here.

One, you believe this is true, and that it is somehow relevant.

That means you are arguing for more gun restrictions. Which means you are a person that makes it harder for me to preserve an important fundamental right of gun ownership.

The second is that you are playing the part of an ignorant rube that plays into stereotypes of gun owners which are ultimately self-defeating to anyone who actually cares about the issue.

Either way I can’t come up with a way that you are simultaneously making an interesting and honest argument.
I am currently born near to Verdun

> The amount of shells fired at the battle of as Verdun is so extremely high that you find layers of shells everywhere

On the first onslaught on the city, it is estimated the German fired around 2 millions shell on Verdun in two days. [1]

It is hard to imagine by today living standards the hell that people lived there.

> The land is literally filled with shells, bullets, scrapnel everywhere. Some are still live and just brought to the top of the soil by farm tractor machinery

Some forest area are still today considered the 'zone rouge'. There is still so many shell inside them that the access or activities there are forbidden [2].

Even in the area not considered 'zone rouge', it is still pretty common for farmers or forest workers to find back non-exploded shell regularly, even today.

After one year of offering our service to some customers, as an on-premises service, we have launched the cloud version of our image optimization and processing tool, imglab.

We are happy with what has been achieved in terms of features:

- Support for modern image formats like WebP and AVIF.

- Smart cropping, including face detection (and many more options). [1]

- Easy watermarking. [2]

- Image composition and custom masking. [3]

- Image animation support for GIF and WebP.

- Native integration libraries for Javascript, Ruby, and Elixir.

- A friendly but powerful API (with what we believe is good documentation [4]).

Features we are working on right now:

- Experimental support for JPEG XL (we are really excited about this new format).

- Complex text rendering, to label images and create banners.

- Native libraries for Python, Go, and PHP.

- NSFW detection.

We are happy to hear some feedback and comments from you about our new product.

The atheist case for free speech
Surely it can't be worse than Finger Family or other such crap?
I don't remember the specifics, it was around the 1.0 release of meteor, so... eight years ago? But the core concept was sports betting dashboard, live updating the odds. So updates were coming in thick and fast, hundreds of betting positions would change every couple seconds as bookies would try to boost their margins during games in progress.

In testing it was beautiful. With simulated updates on local machine, instant updates. Instant. Everyone's happy. Deployed to the server, and connected to the data firehose? Feedback is still okay, with just the clients employees and us browsing every now and then. Slightly slower, but hey it's on a remote server now, that's got to be the issue.

Went live, client ran the advertising campaign, and users flocked. Thing is, they flocked all during the same time, when the games were on. And updates were coming fastest while the games were on. Both of those things multiplied together to firmly peg server CPUs at 100%. Clients were also not thrilled about throwing more and more boxes at it to try to stop the bleeding. Resource consumption was going up geometrically with user count, something I hadn't seen before with any technology stack.

All in all, it taught me there is no such thing as free lunch. You pay somewhere - worse developer experience, more resource requirements, development costs and time. No such thing as a silver bullet.

Also, keeping data in sync without transactions in a Mongo cluster provided endless educational entertainment. We needed to process incoming payment confirmations from the bank, and update the "credits" balance of users. Entirely too often one of those would fail, especially under load. I hear it's gotten better, but I still refuse to treat Mongo as anything but a non-authorative cache since then.
I'll go against the grain and say don't follow Stronglifts or Starting Strength (although the book is good if you're interested).

The problem with both is that they overindex on squats and on 5 rep sets. You want to get a mixture of the number of reps you do per set, and doing squats as often as they recommend will turn you into a t-rex. Plus, when you fail at a certain weight (which you're bound to do), then there's not the flexibility necessary to help you push through and so you get frustrated. I know--I've been in that situation with both programs.

I've recently taken up GZCLP[1] and I'm very happy with it. I'm already doing, 3 months in, more weight than I was doing on either SL5x5 or Starting Strength, and I'm over a decade older than I was when I did this programs.

Dunno. In uni I vandalized Wikipedia (oops, I mean created a hoax) with large, believable edits to generic/major articles like "Tree". My edits stayed up until I grew up years later, felt bad, and took them down.

I don't think Wikipedia is as closely vetted as we assume. For one, it's just so much cheaper to create content than it is to verify it. It's pretty amazing that Wikipedia is generally as high quality as it is with this in mind. And one reason why is that I imagine these types of bad actors (vandals making convincing edits just to be a jerk) are relatively rare.

I reckon most of Wikipedia's bad edits come from low-effort vandals and people trying to game high-value articles that have lots of eyeballs.

> If two threads lock a mutex at the same time, wont both of them think they both hold the lock?

If that is possible to happen, you don't have a correctly implemented mutex.

So no.

> But then, if there’s a way to lock a mutex so that it’s impossible for two threads to do it at the same time, why not use that mechanism to modify whatever shared variable is in question?

Because it's fiddly and hardware-dependent. Do you want to rewrite your concurrency code, just because you moved your program to a slightly different processor?

Also, adon't you need other data types than a bit (or a small integer)? The hardware-supported exclusion mechanism certainly won't know about strings or your ApplicationFactory class.
You're probably right. Given they seem to be using glass, I'd say it's both too heavy for space (?), and too costly for earth. I guess I'm hoping they take this technique to cheaper easier materials so I can slap this on top of a van and get decent power in a variety of different conditions.
One of the attached screenshots made me deeply nostalgic because it reminded me of a time when GUI icons were both elegant and easy to comprehend and distinguish: https://bug213945.bmoattachments.org/attachment.cgi?id=30701...

This era ~15 years ago must have been peak GUI design, with many applications being both beginner-friendly and powerful. And if your grandma called, you could easily steer her through menus over the phone. Nowadays, good luck describing the latest incarnation of the hamburger icon over the phone, especially when all the other monochrome line drawings look quite similar to aging eyes.
This sounds plausible.

Judging by the size and description of the object it was not this though.

A while ago there was a big court case in Bali in which an Australian who was travelling there was accused of importing drugs from Australia. As part of their defence they claimed that the drugs found in the luggage was not theirs and that the most likely explanation was that it was evidence of some type of interstate drug smuggling operation. During this time a high ranking member of the Australian Federal Police came forward and said that it was well known within the AFP that criminals were using unsuspecting travelers luggage to smuggle drugs. At the same time people started coming forth claiming that they had returned home from travelling overseas and found drugs in their luggage. Scared and not knowing what to do they flushed it down the toilet.
Yes this was the 70s. At the tail end of my time there were indeed knights with swords and (checks on google) halberds, and the Space theme guys had little doohickeys that were presumably meant to be ray guns - at least that was how we used them. With hindsight one could see that this was the thin end of a wedge, but contemporary weapons like guns and cannons would still have been very off-message.
