> For example, I've been meaning to research reflective blinds to see if they do more than normal blinds at keeping out heat.

I can confirm they work. It's much cooler in my small flat when they are closed for day, even though they are inside and a little warm. On a sunny day, my outer wall heats up to 60°C. Inside temperature can be 50°C with blinds open or 35°C with blinds closed. This was with outside temp 30°C and wall directly exposed to sun.
I’m no philosopher but this sounds incorrect. You can prove that many things couldn’t exist, and therefore prove that it doesn’t exist.

Like an integer greater and less than 0.
That would be a really neat project: printing a functional transformer as a single piece.
Of course it has. There are many cultures where it was normal to simply dig a hole in the earth and put the body in there, either directly, or wrapped in cloths or in a wooden casket.

The composting happens slower that way, but it still does.
Its funny, on a rare occasion, I too have saved some content as a PDF - more so for archiving rather than for offline viewing...But i guess i never thought to scale it for all/most of my bookmarks. It seems so obvious now after reading your comment. However, my experience with PDFs has been negative. From filesize to slow booting of myriad pdf viewers, etc., it just seems like viewing stuff in native html, text is better - at least for what I've experienced. Further, my preferred browser - firefox - leaves much to be desired in this arena of generating proper PDFs, and i end up switching to chrome (bleh!) just to "PDF something" that i saw/read online. Again, this function in firefox is not something that i use as often, hence why i stick with FF, and not gone back to chrome. However, going back to your approach....I wonder if i can use a tool - either like this monolith or singlefile, or even pupeteer, etc. - to snapshot web content, but save it into html instead of pdf. I would guess html content is still grep-able (as you noted for your PDF local searches). Hmmm...a local cache of my own offline bookmarks...Hmmm, interesting. Thank you for this inspiration!!
You can spray water on your roof with a garden hose and cool your house. Of course water isn't free either.
They mentioned they spent $500k (in research credits) on all the experiments to actually find the hyperparameters.

Is it only me but Plex never worked stably on tvOS. The transcoding stops every 20 minutes and the movie freeze, forcing me to restart it.
I suspect it's only with the mkv container and when using subtitles...
Besides that, it forces you to transcode, and you need to subscribe to have native decoding.
I use Plex for many years, even wrote and published plug-ins for it, but I could never convince me to subscribe. There are too many quirks that make me think let's wait until it works...
> I think compote and jam are the same thing.

Jam is generally eaten with something else, compote can be eaten on its own or be a "base" e.g. you'd spread jam on bread but you'd eat compote with a spoon. Compotes are jams but in effect closer to mashes.
It's hard to point those out without coming across as a hater, and because they might seem so obvious. Trying...:

With the way transactions and durability work in SQLite, a normal setup will not do more than on the order of ~100 transactions per second without adding additional layers of complexity. Which is completely fine for it's intended usecase of being an embedded, lightweight database and of course is not due to some bad engineering decisions, but due to inherent tradeoffs in how transactions are handled.

So basically it's all fine until you try to use SQLite for something for which it is not a good fit, like a large volume of inserts. Other solutions exist that are conceptually better equipped for this usecase out of the box (Postgres/MySQL/Elastic/etc). Not a shortcoming in SQLite per-se, but rather a practical shortcoming that comes up when you try to use it for the wrong job.

Case in point is TFA which takes the theoretical SQLite database size (140TB) limit and runs with claiming that is the useful limit on how much data you can store in SQLite. LOL! That value is when SQLite page IDs start overflowing and not an estimate on how much data can be usefully handled in a single SQLite database.

SQLite is, by the nature of what it is, not a good fit for big data volumes. Try loading 100TB of data into SQLite and try to run even a single query. Even assuming that you have a hyper-fast SSD, a single query will take days to complete! But it still get's mentioned as a potential solution for that problem every so often. In this post even...

So you could consider those practical shortcomings or ill-advised usage. It depends on the definition/perspective I guess. At any rate, SQLite, even if generally being excellent, is not the panacea as which it sometimes gets sold here on HN. No database is, there are just too many tradeoffs involved.
Honestly, years ago after I took a job that uses git, I converted a Mecurial repository to github. I don't remember what tool I used, but it preserved all my history.

Granted, this was a personal project and I didn't use much branching, but I remember the transition and history were pretty seamless.

I originally started with Bitbucket, and then transitioned to a small hosting service after Bitbucket had extended downtime. (I just had to update my Mecurial repository to push to a new host.) Then, the transition to github was almost as easy.

(If only I could remember the tool I used. Maybe my private Mecurial host allowed pulling with git? I just don't remember!)
It's called evaporative cooling, and until recently the principle was the way the vast majority of Arizonans cooled their houses. (They are called swamp coolers down there.)

It only works in dry climates, but it makes such a difference.
We used to buy from Amazon since it was a stamp of quality. I tried buying a usb-c cable for my mac mini, and it was terrible. So many brands and no way of knowing what to get. Today you might as well buy from Ebay.

What online store exists today, where I can be guaranteed to buy quality things? Do they no longer exist?
There is a clear sustainability advantage in using hydrogen since we can produce it trivially. Helium is a very limited resource, and its the most challenging to contain due to its small size. Plus the hydrogen delivers so much more lifting force per volume that some extr mass could be used for safety measures.

The point about remote work is one interesting downside that I haven't seen discussed before. But it's very real in my experience as well.

Even just from running fans, my electric bill in summer is much higher in months when I'm working from home frequently.

I wouldn't be surprised if I consume more energy cooling my house during a work-at-home day than I do commuting round-trip on the subway.

From the article on London:

> To understand how more of the Central line could be cooled down, just look at the Victoria line. In 2006, a similarly experimental groundwater cooling system was installed at Victoria station to lower temperatures in mid-platform areas. In 2011, TfL completed the installation of 13 ventilation shafts throughout the Victoria line, while the new fleet of trains running on the line allows TfL to operate a regenerative braking system, which returns power to the rails when a train brakes. And when a whopping 38 per cent of heat generation on the London Underground comes from trains braking, that’s a pretty big deal.

It's basically another example where sensible design can make a huge difference.
I can definitely imagine this being really hard to work out in an equation, but I'm somewhat surprised that this implies that it has been difficult to come up with experiments that would give data that might help figure this out. Surely we have ways of measuring air vortices and pressure that would clarify a lot of what is happening to the air flow?
I have found (in mild but sometimes warm South Africa) that the best bet is to prevent the sun from getting through the windows.

Curtains/blinds are not nearly as effective as external shutters or some kind of external blind.

I make my own frames with light coloured textile stretched across it that I attach over the sun-facing windows, which has a dramatic effect without completely blocking out light.

I'm honestly shocked that's possible after living in the northern Virginia area for a summer. It was miserably hot/humid for the majority of the ~9 weeks I spent in the area.
All the families stuck in cages on the border and those whose kids died from being refused vaccines may disagree with you.

Yes, this is pulling at emotions, but I'm appalled at how well everyone is ignoring or brushing away the awful things that are going on under the guise of "many people disagree".

I agree there are parts of him that are worthy of respect. But those parts are shadowed by all the parts that have been treating humans other than him as just pieces of garbage.

Nobody deserves to die. But some peoples death can spread a sense of relief because the survivors won't have to deal with all the misery that person was spreading around.

The problem is all of the concrete. Get outside the heat dome and it cools considerably. You just have to rethink the building pattern. (White roofs with water collection would be a good start.)
Anyone else think this is on purpose? Now they can remove all third party sellers from their platform and cite a trust & safety risk. They've been neglecting sellers on the platform for a decade. Why else would the API be absolutely ancient? A huge change is coming.
Thanks a lot quickthrower for your comments. Much appreciated.
Not to diminish the issue at hand, but your quote (or rather, what you left out) makes it sound worse than it is. The full sentence is:

> More than half of the respondents said they either had a negative experience while applying for engineering internships or knew another woman who had a negative experience, such as being subjected to gender-biased interview questions and inappropriate remarks, or observing a noticeable lack of diversity when they interacted with company representatives during the interview process.

This reminded me of zero electricity air-con made of plastic bottles:
https://www.straitstimes.com/world/zero-electricity-air-con-...

The hot air flowing from outside through your windows could be compressed making it cool.

I wonder if there are existing, not so ugly commercial products providing that. This could be a green alternative for air-conditioning.
The odd thing is eBay's quality is now easier to assess than Amazon's.

If you liked that alias, check out tig, which is a very simple TUI for git. It gives you a browsable graph, and other nice things. It also does "tig blame" with going back to revision before a specific line with a single key shortcut.
That is false in the case where the mass market dramatically improves global supply chains for batteries/storage. When the world has low cost batteries, solar energy will dominate due to the fact it is approaching order of magnitude lower $/kW costs than extraction fuels.

If you're old enough to remember GWB being in office, contrast how people thought about him then (which was similar to Trump in a sense) to how they think about him now. In some new future republican administration, people may think similarly about Trump as they do now re: GWB.
Am I the only one worried about this card for other reasons? Didn't Apple take a sales hit because their stuff is too expensive and the average American doesn't have a lot of money? This seems like an unethical way around that little hurdle.

Making it easier to go into debt to buy the next Apple product is a worrying pattern to me.

This is fantastic marketing by Apple--tons of articles about their new credit card. This is at least the second thread on it here.

The first and most important step in the marketing journey is awareness in the mind of the consumer... everyone here is now well aware that Apple just launched a credit card!

And for what? Just writing down in a "support" page what everyone already knows about credit cards: if you put them in your pocket or wallet they will get marked up.

Another step in marketing is product differentiation--why my product is better than yours. By creating a product support page for their card, Apple is implying that you should care what happens to an Apple card--which helps imply that it is somehow better, more valuable, than a boring old regular credit card.

Apple gets accused of being a luxury fashion company. But this card is no more expensive than any other rewards card. It's not actually a luxury product.

I think it's more accurate to say that Apple is extremely good at employing luxury fashion tropes to market their regularly-priced functional products.
Animation Excellence: A Eulogy to Kim Kaphwan's Pants [video]
For Linux cli tools the obvious (to me) answer is IoT devices. These devices are typically pretty lacking in terms of hardware capabilities. So for common tools having them as small as possible allows them to be distributed on a wider range of devices.
I don't think it is a maturity thing. It's a you have customers and business requirements to satisfy and if certain criteria are not met than the feature is kind of useless. I work at an org with around 5000 people and there is no way any engineer could know all of the business requirements for an application, there is just too much to know.

I agree about keeping the original currency, but I don’t buy the future- incompatibility argument. Even comparing current dollars to past dollars needs to be taken with a grain of salt and some reflection (though, granted, inflation is not so quick as forex), but when the specific news event happened, the dollar equivalent number had the same value as the euro-denominated one.
When was Amazon ever a 'stamp of quality'? You can still buy a brand-name cable from Best Buy or other retailers that people used to use before everyone was trying to save a few pennies.
Unveiling Elite Developers’ Activities in Open Source Projects
My more than 8 years old Motorola Defy begs to differ, as does the equally old Ainol Novo tablet I bought around the same time. Both devices run Android 4.4, an older but still usable version for which new software is still produced. The Defy has a replaceable battery, the Novo does not but both still work fine on the original versions albeit with a certain loss of stamina (Defy: 3 days on a charge, Novo ~4 hours of actual use/about a week standby).

In other words, yes, you could and can get Android devices which last for a long time. I does not need saying that both the Defy as well as the Novo were far less expensive than the 'equivalent' Apple devices - where 'equivalent' means 'iPhone 4' for the Defy and nothing for the Novo as Apple at that time did not have a mid-sized (8" 1280x768) tablet.

I guess go all the way around. If you're not burning fuel to move, and time isn't a factor, there's no obvious downside. I would guess that a jetstream-bound airship taking the long way around would still be faster than an ocean-going container ship in most cases.

No. Worth of respect ain't something you give out freely to anybody who lived just because they earned more money than most no matter what. It has to be hard earned with some proper hardships and moral decisions on top of that.

At least that's how my respect works. YMMV
I don't think I'll be able to do it when I'm older. Heat stroke is a serious thing and if I ever had a sense that my body wasn't good I'd 100% use A/C more.

It used to be when I wanted a quality item, I'd click "Ships from and sold by Amazon". They removed that option. Now I cancelled Prime and either buy from other well known retailers, or click "Condition: Used" on EBay. Amazon now is just FBA Alibaba with same lack of quality control.
I really liked the content, but at some point it felt too good to be true. Links to feature screens or walkthroughs might quell that doubt without compromising on messaging.

Spring boot + jOOQ + modern java is probably one of the easiest ways to build java services right now. Spring has done a good job at mostly just getting out of the way. Nothing I've seen with spring boot would have lead someone to write bad code any more than using guice.
The best transport option might be smartrail (similar to http://openprtspecs.blogspot.com/2011/11/climbing-chain.html but steel wheel/LIM and faster).

Smartrail and PRT are designed as a point to point separated-grade network carrying on av. 1 person or a pallette of goods. With a hanging rail you don't need heavy batteries, parking for the vehicles, you can run a pod straight into the factory to pickup goods, and large/rich places can pay to have track straight to their door.

You can prefab the rail and as land usage is just poles in the ground it can be rolled out over fields etc quickly. Track is one-way to eliminate junctions. Pods are on-demand ie. No waiting.

Accessibility improves, you can use the top of the rail to generate (solar) power, run highspeed internet cables in the rail to improve comms across a country, and save on distribution center logistics as you're going point to point.

The last mile may possibly be an issue, but forklift drones and bicycles can take most of the load I feel.

Drivers for this are that it would go fast (200mph+ as light pods so little wear), can go overnight (sleeper pods), you could buy track to your door, personal transport (like a cinema room if you want). The main real issue with cars is that there's a large lobby behind what is a legacy transport solution...

By way of example, UltraPRT has been running flawlessly at Heathrow airport for 10 years, was built on time, on budget, and performs exactly as predicted/modelled.

Straight from the first paragraph of the Hypotheses section, emphasis mine.

>Also called Chimney effect or Stack effect, observes that warm air (from the hot shower) rises out over the shower curtain as cooler air (near the floor) pushes in under the curtain to replace the rising air. By pushing the curtain in towards the shower, the (short range) vortex and Coandă effects become more significant. However, the shower-curtain effect persists when cold water is used, implying that this cannot be the only mechanism at work.

Scientists investigate and prove things that are "common sense" things all the time because the "common sense" answer turns out to be wrong.

Redesigning our systems to provide more control over Off-Facebook activity
DeepMind Co-Founder Mustafa Suleyman Placed on Leave
OpenAI most likely spent 6 or even 7 figures to produce GPT-2 model. The guys who wrote this article mentioned they spent $500k to replicate OpenAI’s results. Each training run costs $50k, and they needed many runs to find the optimal config. Note that the GPT-2 paper had already described many crucial details (eg dataset). Without those details it would be a lot harder to do this.
Dear David

I'd like to know what's on your face,

When you think about how you left this place,

A thought of pride?

A thought of sin?

You worked so hard,

You built,

You played,

And now you'll rest inside a grave.

What motivations do they have to change it? Amazon has very little incentive to change an API that is a cash cow. The AdWords API is much the same. It's a SOAP api that largely hasn't changed in 5+ years.
