> The second operational aircraft[40] designed around a stealth aircraft shape and materials, after the Lockheed A-12,[40] the SR-71 had several features designed to reduce its radar signature. The SR-71 had a radar cross-section (RCS) around 110 sq ft (10 m2).[41] Drawing on early studies in radar stealth technology, which indicated that a shape with flattened, tapering sides would reflect most energy away from a radar beam's place of origin, engineers added chines and canted the vertical control surfaces inward. Special radar-absorbing materials were incorporated into sawtooth-shaped sections of the aircraft's skin. Cesium-based fuel additives were used to somewhat reduce exhaust plumes visibility to radar, although exhaust streams remained quite apparent. Kelly Johnson later conceded that Soviet radar technology advanced faster than the stealth technology employed against it.[42]

I understood it as manufacturing/extracting the right molecule.
I think you're confusing async and parallelism. In multithreading, the computer will switch between multiple tasks whenever there is nothing to do, such as waiting for I/O read or waiting for a network packet to arrive. Things don't happen at the same time, it's just a more efficient, dynamic scheduling of a sequence of tasks happening one after the other. It's not physically possible for a multiple threads to happen at the same time unless they are on separate cores. In my use-case, hashing 200000 files on 7 separate hard drives, the only way to speed up the computation was to read from all 7 drives AT THE SAME TIME. There is no way to schedule 10^6 disk reads and hash operations into a single thread of execution that will reduce the runtime. Those async tricks can work in a more complicated program but you have to understand, I was ONLY reading from disk. The hashing step was faster than disk read (thanks xxhash) and the data was written to a sqlite file in a RAMdisk instantly so pretty much the entire runtime was spent reading from disk. multiprocessing was able to parallelize that unambiguously. Personally I don't trust python's multithreading because I have no control over whether it executes on one core or multiple cores, and in the world of parallel (not async) it is a very common convention that processes are parallel, while threads are async.

However, that being said, I'm open-minded. I will try to benchmark reading from multiple hdds using multithreading and compare bandwidth to the multiprocessing approach. How's that?

> No, actually it's not. None of these can satisfy the energy needs.

Of course they can, and already do in some countries.

> We have data[1].

Or at least a TED talk. Checking it out...

1:26 "From 36% to 31%": Well, it certainly dropped, but it doesn't look from a quick scan as if that trend is continuing after 2010. Looks like it goes up after 2013. And, indeed if I check the source he used, the BP Statistical Review of World Energy, it has figures now up to 2019, which show we're at 37% so the trend has reversed in the right direction. Also, that talk was given in 2016, so why are the figures only up to 2013? I was able to get last year...

Moving on...no, wait, that graph looked a bit weird. That "arrow" was meant to look like a trend line, but it's actually just hovering above two points. What're the rest of the data for, decoration? That's just two cherry picked points! That isn't statistics, it's join-the-dots.

We're less than 2 minutes in and it's not looking good for the "we have data" video.

2:07: "There's just a lot of poor countries that are still using wood and dung and charcoal as their main source of energy": ironically, these are carbon neutral, but at any rate, these are not the countries that have the highest CO2 emissions, so why are we trying to suggest it's their fault?

2:44: "Barely makes up half": not true anymore; renewables have overtaken nuclear and as mentioned, have reduced the usage of fossil fuels already.

2:50: "Let's take a closer look in the United States." - This seems a bit like talking about how to get to the Superbowl and suggesting we take a closer look at the Cleveland Browns. Would it not be a good idea to look at countries who're actually good at renewables?

3:15: "People think of California as a clean energy and climate leader": Heh, no, I think of countries and states with >80% electricity from renewables as leaders. California doesn't qualify.

3:21: "What about Germany?": Ah, lets move on from Cleveland and talk about the Detroit Lions...Why is it that the nuclear fanboys always want to talk about Germany, rather than the other countries in Europe who have far more renewable energy.

3:21: "and there's really not anybody who's going to tell you that they're going to meet their climate commitments in 2020.":

Narrator: "They met their targets."

3:36: "Solar and wind provide power about 10 to 20 percent of the time": Genuinely baffled by this one. This guy thinks there's only daylight 20% of the time? He thinks that wind turbines are built in areas that only have wind 20% of the time? Is he a complete idiot?

I think I'll stop here. I've just one more point to add: this guy says he's been travelling and researching this himself, yet his actual graphs came from the BP report I mentioned earlier. Why did the data come from an oil company if they compiled it themselves? I get the feeling that the real push for nuclear is simply a stalling tactic being pushed by fossil fuel interests, because they know that if countries simply rolled out wind, solar, hydro, geothermal, tidal etc today, they couldn't possibly compete and they'd be finished.

What do you reckon?
Ha. :)

You don't think some team at Google is using photo metadata for ads? There's plenty of value prop in pushing different ads to me if you know that I'm on vacation based on location metadata, or knowing that I buy new shoes and take pics of them every 2 months in order to push me shoe ads at that cadence. I'd be astonished if that isn't the case today or won't be tomorrow.
I lost power for a few days during that ice storm. And a number of years later, another storm only knocked me out for about a day but there were people without power for 2-3 weeks. People stayed with relatives and friends, presumably there were emergency shelters, etc. But there was no armed gangs roaming the street in the Northeast and I doubt there were in Canada either.

If I'm reading the 'buy' page correctly, this is in fact only $10k in deposits with $190k in commitments at an unknown future time, similar to Tesla reservations.

A bit different than $200k in hard sales. Actually for $10k you may as well buy your own reservations just for the marketing value of "$200k in sales"

What Is a Microservice
Fast heat exchange could be a useful property if you wanted to, e.g., stop cooking at a well-defined stage both internally and externally. The faster you can cool down the pasta the less the interior will overcook.

I see no good reason this would have better heat exchange than an unrolled plane. It has a slightly lower surface area to mass ratio (assuming equal thicknesses), and I'd expect the ridges to be more likely to trap water and air, giving the pasta a higher thermal mass and/or reduced pasta/water boundary area. I'm not an expert though.

Tangential, but is Etesync and Notes a cheap, unbloated and foolproof app combo compared to paid competitors? And would the existing protocol support a (team) password manager? I would buy that trio if its a healthy business at $2 per month and avoided lock-in. And in future enabled "SaaS" products which is a static site + a safe backend.

It may be just my bubble, but I see TCL still being used, but I don't remember the last time I saw someone use a Tk application that wasn't written by me (and it's been a while since I wrote any Tk for that matter).
There are really only two FPGA vendors that can compete in this space, and Xilinx is the one that's clearly ahead for computational storage applications. They already provide a platform for storage accelerator IP to be shared between this Smart SSD and their pre-existing PCIe FPGA cards that connect to standard SSDs over PCIe or networks. So porting to another accelerator platform probably isn't as big an issue as you expect.

The bigger challenge I see for implementing something like SQLite on a SmartSSD is that you really don't want your database to exist on just one drive, so you need to figure out how to do HA across multiple SSDs while still offloading most of the computationally expensive database operations to the FPGAs instead of leaving it on the CPU. I think this will condemn SmartSSDs to always working at a slightly lower abstraction layer than what the application really wants.
Have you tried the Lite version? I don't have keys right now but they come with hardware all the time and I already have a Suite licence. On the Ableton subreddit sometimes there's giveaways.

It's kind of like a gateway drug, because you can do a lot of stuff on the Lite version but all the "fun" things like all the bundled instruments and effects that let you use it like a modular synth or the scripting and automation goodness come only on the more expensive version.
GDPR Compliance is nice and all, but as long as their staff has the ability to access my data, I just can't legally host most of my business data on that platform.

Other than that and the terrible performance I love Notion and I really hope they get this sorted. I'll even keep paying for my personal account (drop in the bucket, I know) in the hopes that they will.
As the article says, taking the target seriously would mean drastic rapid changes to try and achieve it. Furthermore, it would require worldwide changes - unilaterally restricting yourself would give all the harm but none of the expected benefit.

So every country on Earth has seriously decided that they are not willing to take on the cost of achieving that target; they haven't communicated it explicitly to their voters (because, let's be real, voters don't want to hear bad news), but IMHO that's a serious decision, and not an unilateral one but one that takes into account the will of the voters as well - I'm quite certain that if the necessary changes are actually undertaken anywhere, mandating major restrictions to lifestyles and economics, the mass of protesters will overwhelm the environmental activists and replace the government (with violence, if necessary) with someone else who'll "not take the 2 degree target seriously" and roll back the measures.

TypeScript was in the right place at the right time, and the team prioritized the right features in the beginning, allowing for the great adoption.

But I'd still place TypeScript firmly in the "worse is better" category (products that are technically inferior then the state of the art, but succeed due to circumstance), it's a band aid on top of a the broken JS ecosystem. Its ad-hoc, Hodge-Podge type system and poor meta-programming is sad to see for such a popular language.

I'd rather write TypeScript then JS, but as soon as there's an opportunity to write software that works across all platforms without dealing with JS, and with a type system that's actually built on a solid foundation, I'm taking it.
Is this a new cpu in that sense? I thought this was ARM64?
> and according to the Rust core language developers will not.

Which feature are you talking about here?
But, one potential issue here is that your FPGA now needs to modify the filesystem to write any new results.

Maybe the use-case here is more like transforming the data on the fly. Let's say storing the data compressed, but reading it back uncompressed. This could effectively be transparent to the host CPU, but handled by the FPGA.

The more that I think about it, this data flow sounds significantly more reasonable than asynchronously processing data. Then you could still read / transform / write the new data to the SSD, but you'd limit the main CPU to only sending the read/write IO, instead of the transparent transformation.
EteSync and EteSync Notes: I'd say yes. To be honest, it's way too cheap for what it is. :)

Yes, the protocol can support that, though it's not yet implemented.

Not sure what you meant with the rest of your comment.
Looking for an iOS developer (Any experience level)
Looking to hire or share equity with an iOS developer interested in helping make a live-streaming/social media platform as a part of our startup, Good Vibrations. Contact me at (216) 308-4923 or james.m.rogers@yale.edu if interested. Thanks.

Our movement is rooted in an online platform consisting of hosted gatherings (e.g., worldwide prayers, meditations, debates, etc.), direct connection to services for living a better life, and user content as unbiased and uncensored as possible. It is a place where you can nourish your soul with the growth that comes physically, mentally, and spiritually when someone wants to reach happiness, and others from all walks of life are there to support that journey.

In contrast to current platforms—which in fact are serious perpetrators of unhappiness and derision—Good Vibrations is set up in such a way to prevent echo chambers while still generating communities of like-minded individuals. Perhaps most importantly, the stance of the platform’s content implicitly expected by its users is commitment to what is good. Companies like Facebook, Twitter, and Google could not make such a platform. It is only possible because the managers of Good Vibrations are unconditionally committed to good and respect for the individual.
Don't take mine, please
Exactly this. People severely underestimate the power in communities when this happens. If word gets out that you stocked up weapons and you’re on the prowl for food, it’s going to be a 50-to-1 situation against your favor.

I love the idea of Notion, and I love what the team is trying to do, and I love almost all of Notion.

Unfortunately, it's too slow, at least for me. For a tool like that I need it to be a frictionless as possible, and Notion (for me!) is just a bit too annoying for me to put up with after extended usage.

If you value features over snappiness, Notion may be great for you though. It's an amazing concept! And I certainly understand why they'd choose the tech stack they did...

...but I'll stick with Joplin. :)
They mentioned this:

> augmented with utility-scale storage that currently runs about $200M/GWh and will be at least 2x cheaper by 2030

So storage is a cost, but seems like a relatively small cost, especially if the stated trends continue.

> Frankly, Notion and it’s ilk would not be nearly has great or feature rich without Electron. It perhaps wouldn’t even exist. Trust, it being an Electron app is a good thing for you, despite its limitations.

Google Mail (Gmail) is very successful despite not having an official desktop application, even though Electron and other web wrappers exist. I am confident that Slack, Discord, Messenger, WhatsApp, Notion, among other web applications, would exist without Electron, and the features would be the same.

If you are a macOS user and want to have a better experience with hybrid web applications, I highly recommend Fluid [1] or Unite [2]. They both create wrappers for web applications using WebKit, which performs several times better than Chromium on macOS.

SQLite is an ubiquitous and well-tested piece of software that is going to stand the test of time and survive the next twenty years. There are very few pieces of software that I am able to praise like that with a clean conscience; SQLite is definitely one of them though. You might find it worthwhile to read e.g. about its memory allocation strategy, or its testing strategy.

Also, I don't think that the image files themselves are stored in the SQLite DB file; likely just their indices and metadata.
I don't have a problem with it. This is a good thing for the industry that Google can't continue to offer unrealistic and unsustainable products for free. They set expectations that were hard to meet.

I think this serves as a warning and reminder to users.
The incentives are not aligned, they want to keep the users paying and they will stop if they succeed.

Therefore it's in their best interest to give you illusion of success in bite size chunks.

These services only amplifies the already attractive people who don't need matches anyway.
Describe "interesting" algorithmically so that it applies generally
Yes. As the social animals that we are we need to devote to a certain social duty, wolves, ants, bees, penguins, you name it...any animal that lives in community look for the benefit of the colony, doing the opposite would be unnatural.
Any open source software for displaying and organizing photos as albums?

I already take care of the uploading (I have a big nextcloud server with multiple copies), however there is no affordance provided for collecting albums and sharing them.

And just to clarify, an album to me it's just a list of paths to photos and the ability to generate password protected links that I can share with family members.
Oh, right, the photos shared through this way should hide all exif tags to prevent leakage.
Nice try, Outline marketing team ;)

You're correct, turns out Dropbox does rename the files and I'd forgotten.

It seems you're right about some quirks in their automatic photo saving system on iOS. Ive been using them with Android exclusively and had good support for auto saving pictures of all kinds.

OP, if you're on iOS Dropbox may not be for you.
Quite a coincidence running into you on HN. I recently did need to setup tunneling to access my home cluster and stumbled on your list. I found frp and was up and running in a jiffy. Thanks for the list!
> Google Photos will start charging for storage once more than 15 gigs on the account have been used.

15 gigs of photos is nothing.

Gak. Randomly deleting your photos. No way I'm relying on cloud storage.

I'm a very long term investor. I received a letter a few months ago from a mutual fund, saying they hadn't heard from me in a few years and were going to hand my account over to the government if they didn't hear from me soon.

Two years is nothing when you're my age. I have piles on the floor in my office that need attending to that have been there 5-10 years.
I use NextCloud to share albums, too. You can share a whole folder publicly
The thing I find so deeply frustrating about the narrative here are statements like this, FTA:

> “Facebook started muting, deleting and labeling every conservative political post in my feed,” Mr. Adam said.

I just don't buy it. If someone posts "I like guns and believe in the right to bear arms", that's just not getting muted. If someone posts "I believe in the sanctity of human life and am anti-abortion" that is not getting muted. "I believe in small government and low taxes." Those are conservative political posts.

It's not that conservative political posts are getting muted, it's that false statements and misinformation are getting muted.

The fact that some people conflate the two is not the fault of Facebook or Twitter. Don't get me wrong - I'm sure they've made plenty of bad calls and neither service is angelic. But I just don't think the labeling & muting phenomenon is what people think it is.

Anyway, maybe more places to have conversations is net net a good result after all. Maybe all the world wasn't meant to talk together in a common public square.

How to test your startup idea
Sweden wants you to prep, they sent a letter to every household in the country.

I prepped for Covid in late February or early March, I was pessimistic in my assumptions, but not by much.

Prepping is important, but you also have to be reasonable when you plan, and you have to be aware of what you can't adapt for (e.g I realized that I had to assume water would still be available, because I couldn't store 14+ days of water in my apartment).

Most of the people who are normally labeled preppers don't have a reasonable assumption of what they prep for. So they try to prepare for the end of the world, not because it is realistically going to happen, but because they need to control things.
While this has become a thread for talking about alternatives, has anyone found a solution with a premium Latex + markdown experience? So far I've found VSC to be the best experience.
I’m late to this thread and it makes me sad because this is such a fun subject. People stockpile weapons but rarely stockpile knowledge for these situations. For example, can you propagate food bearing plants without seeds (they’re mostly hybrids now)? How about basic water sanitation and waterborne illness treatment? A little bit of knowledge is vastly superior to stockpiles of weapons.
