> Compare relative volumes of materials. Brake dust is always going to be a much smaller source of particulate matter in the air than tire dust.

It's not a fair comparison, because you don't wear through the entire tire material as extensively as a brake pad. Fortunately we don't have to back of the napkin this one, there's lots of research showing brakes are near peers or exceed tires in contribution to PM 2.5.

As to your second point that brake material might be less harmful -- there is some initial research on how composition mediates impact.

Aluminum, sulfate, nickel, arsenic, and silicon seem to have the strongest relations. Aluminum is a frequent abrasive in brake pads, they aren't merely contributing some form of benign 2.5.

I can't do a comparison, you might be right it's "less bad" than tires, which contain other heavy metals. But I do not think the research is powerful enough to precisely settle that question beyond the overwhelming academic consensus that both are bad and we should definitely try to reduce both.

Yea, that's now how SQLite has ever been sold. All the other comments on this post have since shown just how useless the "serverless" label is for this.
It uses Thunderbolt 3. Same connector, but different protocol with 2-4x the bandwidth.
I'm reluctant to spend that much if it can't even fully power my laptop.
I didn't make the argument, the other poster did.

It doesn't matter what definition came first. It was bad back then when embedded and in-process already existed. Now it's even worse.
no, it was a special call center software called vacapo.
But SQLite has rdbms features. I remember being able to show tables and do SQL queries in SQLite DBs.
To be honest, that sounds like the reasonable and fair thing to do when a foreign company is violating your laws on the internet. First tell them to stop, then block them. Not every country has this "safe harbor" concept that the US does, so you may have to take responsibility for the content you host if you want access to those markets.

I'm really eager to know how long ago and what kind of GIS software you used.
On Android: being paranoid about multithreading in all the wrong places before I stopped worrying and love the main thread.

Move actual work off thread whenever possible, but never try to integrate off threat memory access by hand using synchronized and friends, just enqueue your final result plumbing on the main looper.

Be paranoid about multithreading in the right places, particularly when you hand a callback to some black box. A callback that checks the thread it's running on to enqueue itself on main if necessary might become a familiar pattern. You might start to hate all callback methods that don't return void.
The use case for faster connections isn't usually so that you can download faster from a single source. It's so that you, the spouse, three kids and the dog can each watch their own 4k stream while downloading software updates for six laptops, six phones, your fridge, your microwave and two dozen smart lightbulbs.
I'm not sure how you missed it, but right from the main Reason web page(https://reasonml.github.io/) there is a link to the Github repo for one of the ReasonML syntax (https://github.com/facebook/reason) which has a link to the latest Release on npm which was four months ago. Where did you get the 18 months figure? (You might have stumbled upon some old docs). There is also an important PR in progress for async syntax extension, which will form the next release.

That Reason repo is just for the parser which is only one of the many pieces of infrastructure under the Reason umbrella (an important one though). Also follow BuckleScript, and esy for example.
I fail to see why you assumed I wouldn't want a thunderbolt 3 dock.
tl;dr This old Pandemic II meme fluffed in scientific jargon: https://files.catbox.moe/lenadr.jpg

The only actual purpose of this paper is to advertise Taleb (and his books): Wuhan virus worse than current predictions? He's definitely going to remind people about his "genius" prediction that it could be worse. Turns out to be not such a big deal? Nobody is even going to remember he wrote this.
Again, it's not like there's no work to implement it but … do you think that's more or less complexity than implementing CSS Grids, text layout systems for complex scripts, building a high-performance JavaScript engine, etc.? The browser teams are not shy about saying when they think changes are important for security, performance, or reliability so I'd consider it an indicator that it's not a huge part of their ongoing efforts.
SQLite is amazingly prevalent as well. Your own phone probably has hundreds of SQLite databases on it. One challenge with SQLite, though, is you have to download the whole thing to make use of it.

Shameless plug, but I made a fun side project that allows Amazon Athena to read SQLite databases from S3. https://github.com/dacort/athena-sqlite
I'm far from an expert on such things, but I like the adjustable fixed-price model (like digital ocean).

Whenever I see a price like 0.0002$ per hour, I feel like they're trying to mess with my intuition.

That's especially applicable to data-science, because you're not worried so much about automatic scaling, you just don't want to be surprised at the end of the month.

I don't know if you can match digital ocean's prices (they offer managed postgres, for a fair comparison), but if you can get close then you have a chance.

I don't see that much honesty and openness out in the open that often. So thanks!
Yeah, in the advent of byte-addressable NVM... I think we have to rethink a lot of stuff and I'm sure we can get rid of a lot of stuff, which isn't needed anymore or should be replaced with light weight components. I'm trying to achieve some of this with https://sirix.io. However, I hope more and more people will get involved over time as it's of course completely Open Source.
It looks really nice!

I was wondering if you could add power output per port, and total, in Amps...

Reason that I ask is because someone might want to power a whole bunch of Raspberry Pi's off of a single USB hub, and if it doesn't have the requisite amps (~3.0 Amps per socket), it will probably burn out, or power will probably sag, and that wouldn't be fun!

But, other than that minor "would-be-nice" -- great site, all in all!

I think people are looking for this review in Nature, where they asked a bunch of ecologists if we could eradicate mosquitoes and the consensus was basically fine with it.

https://www.nature.com/articles/466432a

I think there's even an argument to be made that we should increase our risk tolerance relative to the scale of the harm, and if you study mosquitoes for even a little bit, the harm is off the charts. Fortunately ecologists pretty uniformly agree this is an easy case.
I've never used one but imagining to go by night train from one part of Europe to another gives me a feeling of travelling somewhere as experience instead of it being a chore where being-en-route rather feels like not-being-there-yet.
I always wonder how one could enforce CCS via forestation. How can you be sure that the forest won't be cut down and never replanted? After all the idea behind capture certificates is to buy and forget.

> Same thing with DRM - its scariest because one day it will work.

If corps really needed DRM to work well, it would work well already. The reason that it doesn't is that there is no business case:

1. The music industry has mostly (heavy emphasis on "mostly") woken up to the fact that DRM does not stop piracy. Only a good user experience stops privacy. Hence why piracy stopped being a big problem once streaming services like Spotify became available.

2. The movie and game industry only rely on DRM protecting the initial wave of sales right after the initial release. When the DRM of a AAA game gets cracked 90 days after release (as is usual for Denuvo afaik), it doesn't matter much because 95% of sales are already done at this point. Same for movies. The long tail is impacted a bit by the movie or game being available on piracy sites, but most customers still go through the official sales/streaming channels unless they're absolutely atrocious.
I've seen SCSI adapters of many types - SD card ones as well, don't have any direct product I could link, google pulled up many avenues - including this: https://www.crucial.com/usa/en/upgrades/sgi-%28silicon-graph... though didn't see SGI on list, so hard to rabbit hole that one without using live chat perhaps and may well be a legacy placeholder that time forgot.

Though network booting and storage may well be an easier avenue and cheaper. If you already have a NAS, that may well be the easiest path.
As posted to a sister comment, I think Nature's review -- discussed in Radiolab -- is what people are thinking of.

It'd be better if they were transparent about it and you could see these actions clearly instead of having to glean it from a looking glass or from in country probes.
If you're only after a power adapter for your X1C6 + iPhoneX then this Anker device will certainly work.
I would however wonder if you really need 100W power, 75W would seem sufficient.

Edit: if you plan to use a USB to lightning connector for your iPhone X then indeed the 100W is needed as apparently this device splits power evenly (50W+50W) between the two USB C. A comment however says it's not fast charging the iPhoneX when they are both used, so now I understand your dilemma.
5 references and no quantitative treatment of a very very serious topic like nCoV. Taleb can publish whatever, but why is this grabbing HN front-page ?
They can simply outlaw possession of the equipment for connecting to it. Kind of like how guns don't make it incredibly difficult for oppressive regimes because they simply don't allow everyone have them.
I’m thoroughly convinced google will never be able to produce light weight consumer software. That was their second try at a “light weight operating system” and they so wildly missed the mark both times.
The Open Book eReader will be a real thing you can buy eventually
Sorry, to clarify, you technically can get enough bandwidth for 4k@60hz out of a USB-C port, but you have to abandon the data lanes for more DisplayPort lanes. (I.e, give up all of your USB 3.0 ports and gigabit ethernet or similar-speed ports). So, "adapters" can do it, but docks generally can't.

https://www.bigmessowires.com/2019/05/19/explaining-4k-60hz-... has the specific technical details.
What is the difference between one server with many TB vs multiple servers with less space?
Been wanting one of these machines for years, but they are sooo pricey it is insane. Mainline Linux support will be good, but I tbh I would be running IRIX as intended.
This really didn't make things any less confusing. If anything else, I'm more confused by just a massive spam of product tiles as the first thing I see. It feels like I misclicked an ad in my Google search and ended up at a knock-off product website from abroad.

What you really need to be doing is making recommendations, product breakdown, and even label things as your "choice" and why. Right now, it just looks like a glorified affiliate link farm and that feels dirty.

Spamming users with a wall of product is not the solution.
This. I grew up as a Seventh-day Adventist, and buffets were a frequent dining choice for my family— only because it was possible to have a good lunch without any meat, and with as much dessert as one wanted.
Definitely cool for geek points but can't be terribly power efficient. Wonder how a NUC installed inside one of the drive bays would compare?
Spot on.

Why Aren't Operating Systems Getting Faster as Fast as Hardware? (1989)
> Somebody will meet that need. The plastic will be produced so long as consumers demand it.

putting blame only on the consumer, who’s is born into a system that is designed to fuel consumption (in order to survive in society, you need to buy clothes, phones, refrigerators, toys for your kids, diapers etc etc) is not very productive imo

not to mention the effect of marketing in all of this and it’s clear we need an all-round approach from supply-side to marketing to consumer awareness

(all my opinion of course ^^)

It seems like you are determined to be contemptuous of Apple here.

It’s fairly clear that things like sandboxing are good faith efforts to improve platform security against risks that are very real.

It’s also clear that they are seeing their platforms as unified, and attempting to bring as much technology to the Mac as they can, rather than reserving some for iOS.

Without these kind of improvement the Mac platform would have no future.

I can agree that it would have been better for the dream of Mac application space if they hadn’t had to address these issues, but I can’t see where the idea that it is bad faith comes from.
i'm glad to hear it's working out

For everybody that does business in the region.

Helsinki<->Tallin<->Riga<->Vilnius<->Warsaw<->Poznan<->Berlin<->Hannover<->Amsterdam would be a very useful connection to have.

East of Poznan road travel gets more and more dangerous, especially with the winter weather thrown in. Being able to visit those parts of Europe year round without having to go by air would be something I would definitely make use of, especially on an overnight connection.
That’s not what I got from it at all. The precautionary principle and fat-tailed processes that come with extinction-level risks are real. He makes valid and salient points.
Ask HN: Ultrawide monitors, what's your experience been like?
I need a monitor for work that has lots of space so that I can open up different applications side by side. I was initially considering buying two separate monitors but am now considering ultrawide monitors as an option as well. For those of you with ultrawide monitors, what's your experience been like? Are there any brands or models that you recommend? Is there anything I should look out for?

Risk level to the brokerage is different from margin requirements and leverage, but they do trust you more. They don't look at or even know about any other assets though. It's based on your account size, trading experience and strategy. And of course negative balances are always owed.

But the point is that more capital does give you more leverage. The next step is $5M+ mark when you get even more access to trading vehicles.
Thanks, ordering that DeLOCK now! Will get back to you when I test it!

Titan Ridge is an option as well though I want to use it in an x399 Zenith Extreme board (DeepLearning rig) and that might be challenging (in theory it should work but the board is super buggy).
You can use the memvfs module to load in-memory databases if you're using the C API. I'm not sure how many higher-level APIs support it though.

Yep. Every time I see a lost cat poster, I wonder what the owner's thinking. There was even a lost dog poster in my neighborhood stating outright that the dog got snatched by a coyote.
That's misrepresentation of the root cause. The block was there, because it's easy to block. Uber is blocked in Turkey, you can't even access uber.com. Pastebin.com is blocked due to a data leak was posted in there a couple of years ago. Imgur is banned due to pro-terrorism post, AFAIK but I'm not sure. There's no damat (son-in-law) in those cases. Damat is a multiplier but not a reason.
Even if they had that sort of leverage, we would still gain some price for exerting that control. So it would still be a win-win for the US.
Nice job. (But how did we get into this mess in the first case, I ask rhetorically.)
For my next vacation I’m planning on taking the train from Seattle to San Francisco, for exactly this reason. I’ve told people about this and they all think I’m crazy: “It costs as much as flying and takes 22 hours, why would you do that?“ But they’re not getting that the train ride is the point.
This was definitely true last summer, when it was trendy to flight-shame. But human nature being what it is, the itch to travel to the sun is inevitably creeping back, and I’ve noticed several colleagues returning from breaks in Bali, Goa, Thailand and Sri Lanka. They just don’t talk very much about it.
I used to take the night train to go back to my parents as a student back in France. Was a nice feeling, having a bed and reading a good book during the night while enjoying the scenery and the relaxing sound of the tracks under you. I really miss it and would love doing it again. They removed those trains like 10 years ago.

I'll see, I am worried it won't work as well as that LG monitor is like 1st gen bleeding-edge tech where incompatibilities might arise. MacOS users definitely had issues with it at first and those use USB-C connector on the display, but DP/HDMI works fine so far.

Thanks for replying, my comment above was a bit flippant and I just want to say well done on sticking with a training regime for such a long period of time. I've heard coaches say that, at a high level, being consistent and believing in your training approach is just as important as the specifics of the training.

As you say blending high intensity and low intensity is important. Either or is a false dichotomy that it is easy to get caught in, and high/low intensity is better than always training at a moderate intensity.

While effective for you, your session, doesn't resemble an interval session a miler might do. Stampfl had Bannister running things like 10 X ~440 yards at ~60 seconds a pop. Definitely influential, it is still a staple today, but it isn't HIIT.

From my reading (admittedly from a distance background), HIIT is no substitute for long term aerobic development. Aerobic development comes from longer stints at easy paces, through to intervals at 10k pace or just below. HIIT will show results more quickly, but it is a dead end. A 5k race is >88% aerobic, there's no way HIIT is better in the long term or we'd see athletes training that way.
> Keep in mind you're really only able to learn to code if you're able to read English at a proficient level, which only ~13% of Americans are able to do.

Proficiency is measured on a scale — it is not binary.

What specific level of proficiency are you referring to, and what is your source for saying that this is the minimum level needed to learn to code. I will go out on a limb and say that your 13% is folks who can read at a 12th grade level (or thereabouts). Note that in the literature, this does not refer to the reading level of an average 12th grader, rather the level that curriculum developers aim to have 12 graders read at.

Also, what level of coding are your referring to?

I will just say straight up that I can teach and have taught kids who have little or no knowledge of English how to code (e.g., with Scratch), so I think you may need to make your assumptions a bit more transparent.
Nuclear is extremely low-carbon baseload energy with very low land, waste, death, and raw material footprints. In a world of increasing carbon-related challenges, it's very challenging to write off.

We're currently building high-carbon fracked gas plants like crazy because they're cheap. Put some kind of price on carbon emissions and instantly fracked gas is expensive and nuclear is cheap. Nuclear's low-carbon nature is not valued in markets, and that's a great shame.

Look to the Koreans and Chinese if you want to see economical and effective nuclear projects.

It depends on whose perception. Common as in 'the world' is something that we don't really have so you are always going to have to go by some locally colored version of events.

The US eventually did win the space race, but they lost Rounds 1 and 2 to Russia. The United States getting involved in WW2 when they could no longer ignore it ended up getting the formidable American industrial engine engaged in ways that had Japan been a little bit smarter might have seen a completely different ending to WW2.

The US view is that they did all the heavy lifting, when in fact Canada and the UK did given the relative sizes of their population at the time made a disproportionate difference in Western Europe, but America was definitely very important while in the East Russia made the biggest difference. In the pacific it really was the United States that made the difference.

Perception when simplified to the point where it makes no sense isn't the right metric to go by, but with some nuance it can actually be quite useful.
