It's worth point out that there are still plenty of static RAM in modern chips and those obviously don't require refreshing. The CPU cache would be an example, but there are also plenty of internal SRAMs in ASICs and FPGAs everywhere.

The refresh needed by DRAM is also why you can't merely suspend-to-RAM by merely keeping it powered up, the bits will flip. You need a special self-refresh mode that keeps updating every cell.

While implementing suspend-to-RAM on an embedded system I wanted to test that my self-refresh was working correctly, so I decided to test the null hypothesis: I'd suspend my ROM code without enabling auto-refresh, wait a second or so, wake up and smell the ashes. Except... it seemed to work anyway. The data was still here.

It turns out that while the refresh period of DRAM is usually a handful of ms at most, you will still have a relatively low bitflit rate even after several seconds. In hindsight it makes sense: in production you want an error rate of effectively 0% (especially if you don't have ECC) across potentially billions of cells. Most cells can probably hold their value for much, much longer than the refresh period but you need to catch the full bell curve and it needs to keep working across the entire temperature and voltage range for all chips.

After a recent visit to London I've really come to appreciate how fantastic the signage is in the Tokyo railway system. In London I often had trouble finding exits or connections (often following signs only to seemingly run out of directions), but in Tokyo it always seems seamless.
I agree that it is complex and your assessment seems accurate but the problem with Saudi is not that they are opposing the houthis but their tactics of attacking supply lines and bombing indiscriminately. They refuse to use ground troops because they rely on Pakistan for an army and Pakistan does not want to invade. So they continue to do airstrikes on any and all targets like hospitals, kindergartens, food supply caravans, power stations etc and they don’t seem to care.

I worked closely with their reconnaissance aircraft as a foreigner and it’s funny that when they found out I was in Afghanistan they lectured me about killing kids but they are 100 times worse. I eventually left because I was disgusted with the way they conducted that war and did not want to be a part of it regardless of it if supported US foreign policy goals.

So if the Houthis win I don’t know if it’s better long term but at least 5 year olds won’t get blown up on their way to school but a Saudi pilot.
I have been wrong about a lot of stuff in the past. The reason I like discussing things here on HN is because there's a higher threshold of logic over emotions.

You have to look around and see what commercial plans are available to you. Depending on where you are, there may be subsidies available to you. What state are you in?
Yes, 100%. That, combined with Google Maps for routing made any sort of train or metro interaction in all of Japan utterly painless.

The only time I got lost was when I couldn't immediately find a Tokyo Metro station and Google Maps sent me to the JR station on the other end of the mall. Even then, it only took me a few minutes of wandering around to find what I was looking for.
Right, it's only been on the childhood vaccine schedule for 10 years. Most people don't know that nor that there's even a vaccine available for it. Chickenpox is such a mild childhood event that it's widely just assumed that your children just need to get infected with it and a week later they have lifetime immunity. Something like 95% of all adults today had Chickenpox as a child and most people have probably forgotten the event.

10 years for a vaccine against a generally mild week long childhood rash is not really enough time or importance to enter the general public consciousness and it's not really a sin to get your kids infected with it. You're judging billions of people with your own ignorance of their lives.

Why Do Laptop Makers Have Such Terrible Websites
I am selling a product on Amazon that has two colors, black and white. Somehow the pictures got mixed up: the white version has pictures of the black version and vice versa. It was once correct, so I don't know what happened.

I've been fighting with seller support for about two weeks to get this fixed. First they said they need a link to the manufacturer's website for the product (!?) Then when I gave them the link they said I need to upload the new pictures myself (!?) So I did, I downloaded the pictures from the manufacturer website and uploaded the black pictures on the black version and the white pictures on the white version. Now they've just been sending me messages every few days saying "we are still working on this issue." This is for a real simple fix, not some sort of complicated issue, but it's a big issue if a customer doesn't know what they are getting, this should be priority one.
Just a note on wage:

This article seems quite a bit... bias? Or unprofessonial reporting? I can't place my finger on it, but if there are more sources that agree I'd be inclined to believe it. Looking for some education on this so pardon my ignorance.
> The british were instrumental in supporting saudi and arab nationalism

The Saud family didn't overthrow the Ottomans with the British. That was done the Hashemites, under King Faisal, and of course T.E. Lawrence (whose story was told in his own memoir, and later in David Lean's epic film Lawrence of Arabia).

In the subsequent post-WWI, post-Ottoman chaos, the Sauds conquered Mecca from the Hashemites, and established modern "Saudi" Arabia.

The Hashemites fled and established what is now the modern country of Jordan, which they rule today.
Very bad examples.

First, those are their neighbors with which they have territorial disputes, like every other country (as borders where not there when the Earth was created, nor where they god given). Not some colonial grab, just out of pure greed, thousands of miles away, and with no prior provocation or history between the two countries.

Second, Mongols invaded and dominated China. You got your facts reversed. Ever heard of this guy, Genghis Khan?

Third, if we considered the same for the EU/US for example, we'd add the genocide of native americans, the abduction and slavery of 20+ million blacks for 4 centuries in the US South, colonial grabs and wars all over the planet (at some point 2/3rds of Earth were slaves under European colonial powers, not the inverse), tons of wars, the land grab of Mexico (California, Texas, etc), Hawaii, Phillipines, and Puerto Rico, the genocide of indigenous people of the Americas [1], and so on and so forth, plus 2 world wars, the genocide of the Jews, and the only atomic bombs to even fall (and on civillians).

Yeah, tell me again how bad China has been?

You say that, but there will be a document somewhere telling people what the requirement is, and it will probably NOT say "Imagine the maximum possible amount of people that could physically fit, now add ten percent".

I think I can more or less say that we would not have been able to build what we have without RN. At least not with same budget. There is a large class of apps that would suck @ in a webview but can get by just fine in RN with 90% cross-platform code re-use. If you're already a team of experienced react developers the learning curve mostly just comes down to learning how to resolve build issues. And possibly expo can take care of that depending on your app. (anyone actually use expo for real stuff?)

With RN + React Web + [PaaS/FaaS] I feel like a lone dev can be dangerous theses days.

Doesn't mean Flutter or PWA's won't obsolete it eventually, and I'm optimistic about Flutter's approach. Just saying that there's a reason RN is a thing.

Amazon's Black Friday tech deals are full of stocking stuffers – Time (audio)
I once spent an hour or so trapped in an elevator. It was a small building, only six stories or so. A bit of a rumble, and it was just stuck, a few inches out of alignment with the exterior door. I didn't know it at the time, but the elevator had actually fallen up, because it was counter-weighted and I was alone inside, well below its weight limit. It was very old and a relatively small building, so I had no idea that this happened, and I thought it was just jammed at my destination on the first floor.

The emergency brake had kicked in at the top floor, but the doors wouldn't open when misaligned like that. Most of the time I spent in there was the technicians (and, for some reason, they sent the police to talk to me) looking for me. I had thought I was on one of the lower floors, and that's what I told the person on the emergency phone, so they were looking for me in the wrong place.

The elevator was old enough that I guess it didn't have any mechanism for reporting its location, and may have even been a relay-controlled system, which explains why they couldn't find me. After they showed up, it took a fair bit of prying on both sides to get the doors to open. I was surprised when I left and found out that I had been on the top floor the whole time, as they didn't tell me until I was freed. Then I took the other elevator back down to the lobby with the technicians, showed my professor the card from the police officer and explained why I missed class.

The one thing I wonder while reading the article is how they managed to figure out where the elevator was if it was in a blind shaft - they couldn't just go from floor to floor listening like they did for me. I used to live in an apartment in at all building that shared a wall with a blind elevator shaft, and I didn't even realize it for a while because the walls were so thick that the shaft was silent.
>All of a sudden, an outbreak occurs, putting all the immuno-compromised at risk...

I mentioned the issue of being a single US traveler (that got vaccinated) going to a foreign country without vaccinations. It's a single person in the middle of everyone else.

How does the vaccine protect one person in millions (US traveler) but in the US a few unvaccinated kids put lots of people at risk?
In Apple's early days it established a precedent of extraordinary ads. No one wants to violate that standard because they want to feel a part of that tradition and a part of a group of peers that maintains that tradition. Elsewhere that dynamic often does not exist. In the absence of that tradition and other's expectations, good enough seems ok.

Just want to post a reminder that solar cells are already efficient enough and cheap enough to be cost effective for power generation in many regions of the world. I am all for continued research to improve efficiency or decrease cost, but sometimes articles like this one lead people to believe that solar cells are not yet cost effective. They already are!

The TAP card in Los Angeles is good for dozens of local public transport companies. For quite a while, this was not the case; you could only use it on Metro (County-level agency). The integration over the years has certainly increased my use of transit in the area; there are many tiny, obscure transit systems in Los Angeles County and I can ride almost all of them now without having to carry any cash or change. Sometimes you can even get cross-company transfer fares with the TAP. It's fantastic.

I lived in Chicago for 8 years and wouldn't care if I never see it again. But I don't like urban areas in general.
everyone can have their own importance mix for sure. Someone could find Anchorage, Alaska the most important ( and I say that without irony ). But if you want to talk to other people and use the kind of shorthand that all people understand very quickly, then GDP and population are pretty good indicators of importance that everyone sort of agrees to use as the proxy.

To be fair, the entire planet is a freak show catalogue. A lot of countries seem like being controlled by coke monsters currently (sometimes local, other remote controlled). You see a surprising homogeneity everywhere.

It's the US who pretend to be exceptional and to have moral high ground.
People in Bangladesh see their children, and their neighbors’ children, suffer and die of those diseases for which they can receive a vaccine.

People in developed countries are not confronted in the same way by fatal childhood diseases and have the luxury to ignore the consequences of avoiding vaccinations, thanks to advanced healthcare and to the herd protection provided by the majority of responsible parents who vaccinate their children.
I mean on top of the cost. Just reward people for getting the vaccination. Normally you gotta persuade people or pay them for the inconvenience to get them to do something for you.
Do keep in mind that while they are "cost effective" - it takes a few years to recoup the initial investment.
A more efficient panel will repay its value sooner, or will require lower initial investment.

Second, the possible applications -
Low efficiency cells will support low power appliances,
Or you'll need more of them / storage for more power hungry applications.
A more efficient cell enables new applications where weight is an issue.

So you are asking questions to challenge beliefs. That’s called the fallacy of many questions. [1]

I wouldn’t vote you down or have commented if you would just say you don’t believe there is any data to substantiate a claim. But you are clearly trying to ask questions not to illuminate, but to try to advance your agenda.

I will straight out ask you - do you believe vaccines are effective? And do you believe they are dangerous and shouldn’t be given to children?

That’s what I am saying. My work laptop moves between two places - my job with a dual monitor setup and my favorite Bluetooth keyboard and mouse and my home office with a dual monitor setup and a separate set of the keyboard and mouse.

So why buy a more expensive, less capable laptop that will only be used in one spot at home for my personal use instead of just buying the Mac Mini?

Second question is usually why not just buy a cheaper PC? I’m slowly moving away from the Microsoft Windows ecosystem - but I still will be using some .Net Core - and the macOS is real certified Unix that just works.
There's a weird phenomena at play where ignorance has been advertised as a virtue and willful ignorance can be used as a superiority or virtue signal and used to socially position people above others in the same way that other beliefs and belief purity tests end up harming the believer. It seems to be fed by a bizarre ecosystem of pseudo-information that fill the minds of people and discourage critical thinking -- and maybe plays on some desire for social belonging to a group with secret knowledge.

I remember reading some papers and articles on this and how it kind of hacks the minds of people by playing to base insecurities. Critical thought is not really a natural state of humans, so it can be very easy to subvert.
You are right. But let's humor the pitch. What happens if solar gets to 60% efficiency and costs - 20cents per watt?

I don't understand why your upper comment was downvoted since it points at a core aspect of the systemic problem that in a democracy the different branches are supposed to keep each other in check: legislative, judiciary and executive branches. If you have an executive branch without oversight from the judiciary, it just grows like a cancer since the executive government doesn't need to prove anything, and the right to legal defense is vaporized...

I understand why people are distressed, because the press and other media make a lot of noise about imminent disaster. However, markets price in ahead of time any impacts that they foresee, and we can observe that

- Britain's government debt yields, e.g. 2 and 10 year bonds, remain at similar levels to pre Brexit vote, and unlike before 2016, 10-year yields are now lower than US 10-year yields

- in currencies, the GBP has remained fairly stable against EUR and USD.

I have no doubt that there will be some impact. I did not wish Brexit to happen. But I see some positive signs as well (mainly in that this forces EU leaders to sober up).

The same claims were made during the outsourcing craze of the 90 and early 2000s. Companies tried to save money by sending development overseas to Indian sweatshops. They quickly learned you get what you pay for. If you need some backoffice crud app, Crossover will work. If you're building a customer facing app or anything with any significant complexity that requires fixes and features addition, you need inhouse people for the experience and expertise.
