3s load time is crazy high. You need to get below 0.1 second before it feels instant, which would be a huge upgrade compared to most websites (it should still feel instant if you load the ads after that, just so long that you don't change the layout on the page at all).

I have a gigabit connection, so it is not a question about not downloading fast enough, I can browse wikipedia this way. It is a matter of not using so much javascript.
Yeah, nobody actually cares about the guy, they're just using this as another stone to throw at political rivals. Let's first get confirmation of his death. Nothing about this is on the level.

Cliff Click – The Azul Hardware Transactional Memory Experience
I'm not convinced that Spin-Launch is anything but vapour-ware. At risk of sounding like an arm-chair engineer, the G-forces experienced by the payload during it's rotational-phase must be astronomical. Not to mention the aero and thermal loads of slamming into the thick lower atmosphere at a substantial fraction of orbital velocity. The aerospace startup industry is no stranger to dumb ideas getting inexplicably large amounts of start-up capital, so capital itself isn't a reliable measure of their engineering expertise.

We shall see though.

EDIT: g-force calculation in a centrifuge is velocity^2 / radius. A 1st stage probably needs at least 4 km/s. A 10 km radius centrifuge yields a gigantic 1600 gs at that speed. So they're either building a centrifuge the size of a medium sized city, or their stage 1 speed is so slow that why bother with the added engineering complexity of this portion? This is without even considering the thermal and aero problem that emerges with high-speed flight at sea-level upon exiting the centrifuge. I think I'd keep my wallet closed on this one if I was an investor. Is there something I'm missing somehow here?
So many submissions, so few comments.

This is a good article, and an interesting topic. Every seems to be looking for the One True System(tm) to make knowledge acquisition and note-taking effortless, seamless, and productive.

But to me, the crux of all the systems I've looked at lies in the review of material. Luhmann's original Zettlekasten was all about putting the cards in the system and linking them up. By all means write your notes/snippets/capsules/whatever, but they then should be woven into the system, and it's the act of making those connections that is the "Conversation".

Otherwise it's just a write-only brain-dump. Maybe you can search for a single "card", but it's the connections that matter.

Ad's got us here to begin with. Without ads the internet would have been only for the rich.

There would also have been no google, no amazon, no android, no kindles. I'd still be ordering everything from the Sears Catalogue, waiting 6-8 weeks for it to arrive.
I signed up for an account and all I see on the dashboard is...

It's quite remarkable how few accidents happened, at least lately: only 3 events in the last 3 decades. Throughout this period the US and Russia had a combined number of nukes always in excess of 10000, and more than 100 naval nuclear reactors, and many, many nuclear facilities for R&D, for nuclear enrichment, for nuclear disposal and who knows what else.
Thanks for this comment. I've been annoyed by the fact that click-baity articles don't load Instagram content in the past, but re-framing the issue as a bullet dodged and time saved is a surprisingly powerful shift of perspective.
Back in the 90's we half joked that we needed a remote controlled robot with 3 fingers to press Alt Ctrl Delete rather than drive down to the data center at 3am to reboot a jammed server. I sketched "R2Reboot".
Facebook does this too. I'll go to a link to a facebook page and be greeted some seconds later with nonsense about having to login. There's also that facebook login box that covers the bottom of the page.
I had the same experience. I wanted to watch someone's podcast Livestream that was being broadcasted on Instagram (I don't know why they didn't just use YouTube). But I couldn't even create an account. I tried with my desktop and phone on different networks. It wouldn't work.
Organs are edible. You should try it sometimes. They are not waste products. No wonder Americans find these things wasteful. In my experience, even something as simple as chicken. People do not actually eat the whole thing. Half of it is thrown away, just like everything else.

It's very strange to me, because growing up, we'd eat everything. But I married into an American family, and I'm often picking stuff off the bones they throw out. We were raised to eat everything, even the marrow.

> That's a lot of energy that bioreactor-grown steak doesn't have to expend

Sure, but the bioreactor is (1) heavily affected by supply chain issues, (2) dependent on an external source of energy, (3) requires complex chemical inputs that have to be synthesized themselves oftentimes. No one takes into account the whole thing.

Also, monoculture is always going to be less resilient than an actual population of cattle, or pigs, or chickens. But, I guess this is a problem that affects the whole industry.
So you're just making up number because they sound right to you? In the future, if you do some simple googling before you join a conversation you'll sound less uninformed.

I feel like this is a very disingenuous way to put this issue. It's not that people write a program that actually have lines of code like this in them but rather machine learning algorithms operate on our current reality rather than any ideal. With few exceptions a pregnant employee is worse than a non pregnant one so if all employee data is fed into a nice ML black box with all things being equal it's going to start firing the pregnant ones.
That's why when you look up who received the funds you'll immediately see a pattern where large scale enterprise corporations have 100% owned subsidiaries that do nothing more than receive state funds, live for like 2 years without hiring any talent that is specific to their "research" area, and then get declared insolvent because the managers got themselves a big payout.

Most of the funds don't go to startups, and that's exactly what I hate about this paper pushing goldberg machine.

The big consultancy companies like accenture are also heavily involved in this scam. Founding AI startups without a single data scientist or engineer is what they seem to do for a living.
I think they were being sarcastic, given that they're writing it under a pseudonym.
Disney, other film studios, large record labels and distributers, etc, have the ability to place their content directly into YouTube's ContentID system so a copyright claim will generally be denied immediately by one of youtube's bots.
Try i.reddit.com on mobile, it's easier on small screens. Click the cog on the right for options like collapsing comments.
I disagree. Reddit is worse because if you don't have an account, you are constantly pushed to make one, or get pop-ups to download the ad. They also seem to limit functionality, like seeing all comments, unless you have an account.

The Windows installation process is annoying for sure, but once you get through it, you are able to disable or rework everything you mentioned. iOS honestly has everything you mentioned as well; in fact, it's installation process pushes even more services than Windows does, but I never see people complain about it. I find both process annoying, but I forget about them once I get everything setup because it goes away. I don't want a reddit account because I basically only visit the site when a friend sends me a link. I am guessing I can also have their stuff go away if I download the app and sign up, but it's not as essential to me as using Windows or iOS.
Yes, some former releases at least via https://github.com/intel/Intel-Linux-Processor-Microcode-Dat... is what I use during some of my past/present Linux testing
>"These technologies work by combining incoming infrared light with a strong light source – a laser beam – inside a material known as “nonlinear crystal”. The crystal then emits light in the visible spectrum.

However, nonlinear crystals are bulky and expensive, and can only detect light in a narrow band of infrared frequencies.

Metasurfaces provide the solution

Our work advances this all-optical approach. Instead of a non-linear crystal, we set out to use carefully designed layers of nanocrystal called “metasurfaces”. Metasurfaces are ultra-thin and ultra-light, and can be tweaked to manipulate the color or frequency of the light that passes through them.

This makes metasurfaces an attractive platform to convert infrared photons to the visible.

Importantly, transparent metasurfaces could enable infrared imaging and allow for normal vision at the same time.

Our group set out to demonstrate infrared imaging with metasurfaces. We designed a metasurface composed of hundreds of incredibly tiny crystal antennas made of the semiconductor gallium arsenide.

This metasurface was designed to amplify light by resonance at certain infrared frequencies, as well as the frequency of the laser and the visible light output. We then fabricated the metasurface and transferred it to a transparent glass, forming a layer of nanocrystals on a glass surface."

PDS: So, here's the next logical question then: If we have a metasurface, then what are its limits; it's extrema (min, max) -- in terms of wavelength conversion (AKA "use as a transducer") ?

Phrased another way, what are the max and minimum frequencies of waves that can be transduced from one type of wave to another?

Wouldn't it be interesting to do some experimentation in this regard, to try to figure out the maximum frequency that can be downshifted, and/or the minimum frequency that can be upshifted (and to what amount?) -- with respect to metasurfaces/layers of nanocrystals?

And of course -- what are the various problems encountered (probably more important than answering the above questions) when engaging in that line of research?

All I know is that the future looks very interesting, with a whole bunch of new (and possibly very weird!) future transducers based on this technology!

Also, with the right transducers available -- the world would take a step closer to full-on Optical Computing...
This seems like an awfully simplistic first order analysis that doesn't consider the end to end economics of driving.

Location is an economic constraint, and the ability to reduce or eliminate that constraint at will is very powerful. The fact that (some) traffic fills to capacity on a specific road just means there is economic demand surplus for travel between points connected by that particular route at that particular time. This demand tapers off when the roadway reaches capacity because another cost begins to grow exponentially. Travel in congested traffic quite literally causes people to murder each other. This cost, the stress of driving on congested roadways, doesn't seem to surface much because it's difficult to quantify. However, for me, it is the one thing that will cause me to change my plans.

(edit: It's easy to distill 'economic' motivation into profit. That's not my intent here. My view is that there is no intrinsic value of anything, the sun could have exploded 7 minutes ago and if anyone outside of its reach is there to witness it they might catalogue it as ES0481A (in 4+ years). I use 'economic' as an encapsulation of human desire to live and to thrive and its important to me and to this argument from that perspective.)
Yeah. People forget free speech does not mean consequence-free speech.
Not supporting OPs assertion, but. Even with same proportion they will have huge advantage in absolute nos. Also society and government are lot different, changing the way and proportion of people persevere for a particular career option.
Users are not consumers, but product. And untracked users are lower quality, so culling them can be beneficial. So no problem here.
It can also be about initial startup time of the system, not startup time of any individual service. Please follow the site guidelines, c.f. the part about "don't cross-examine" -- this is just a technical tool, I'm sure we both can come up with some ways that it could be useful, even if we wouldn't use them ourselves.

>But systemd needs a few full time adults, not just a patch here and there to fix the launch-while-brainstorming culture that gave us the current situation.

Then start working it on it full time, and get some of your friends hired too? Surely you can find someone to pay for that, if it's useful? What else is it that would satisfy you here? I'd be happy if another group was committing full time to systemd (or another similar open source project) just to fix bugs. I fully support you if you decide to do that.
They are two different, but related, things. There are people who die early because they eat extremely poorly; lots of fats and sugars.

1. If the fatty and sugary foods were too expensive for them to buy, they would not have died from those things.

2. They did not die because fatty/sugary foods weren't expensive. They died because they chose to eat fatty/sugary foods. [1]

Just because X (good insulin being cheaper) would have helped prevent Y (deaths) doesn't mean that <not X> caused Y.

[1] I'm ignoring the fact that truly healthy foods tend to outside the price range of the poorer segment. The analogy only really goes so far here.
... but if you can't collect data on them, you can't target ads to them or sell their data elsewhere, and therefore they're worth nothing to you.

At the end of the day every company wants to make money, or will be bought out by cutthroats who think it's all there is, and this kind of thinking will take hold. Users you can't profit from = leeches.
If you start building a skyscraper by nailing up 2x4s, you won't get very far. But that says nothing about the merits of nailing up 2x4s.

If you start a project thinking, "I'm going to make an object-oriented program", or "I'm going to make a data-oriented program", you are just working with one hand tied behind your back. A mature programmer mixes elements freely with no thought to "orientation".

If you demand simple advice: Don't Be Stupid. It's not helpful, but neither is TFA. At least mine is correct.
For sure younger managers are intimidated by managing someone who reminds them of their dad (or mom? Unfortunately unlikely).

How can startups that are almost all 20-35 year olds overcome this?
I don't have a Reddit account, and every time I use it I am reminded why. Their patterns have taken me from "I should create an account one of these days" to "there is nothing on the Internet that I need to see so badly that I would let Reddit see anymore about me than my IP address." It's almost as if they are taunting users: "give up and create an account, or go home. Oh, and use the fucking mobile app while you're at it, or the suffering will continue."

OTOH, once I get there, a lot of Reddit content makes me wonder why I bothered. :-)
I suppose I don’t have enough experience because I stick to the latest LTS.

I agree that the Linux desktop has its shortcomings, but I still feel that it would be a great option for plenty of people who default to windows today. Especially if they spend most of their time in the browser as it is.

I’ve been a happy Ubuntu user for several years now and I’m not a tinkerer or anything, though I am more technical than the group we have been talking about.
I replaced https://news.ycombinator.com/item?id=27666416 in your comment with the URL it points to. That way people can click directly to go to the ruling, and we avoid the crankiness problem with empty thread links (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). I hope you don't mind!
No one's going to be paying anyone to "engineer" this transition if there's no incentives. You can be as american as you like, but that won't change the fact that oil is basically free. You can't compete with free in a free market.
> Aren't they contractors?

Question is, according to whom. For example, Uber got hit with a pretty big fine in Italy because in the view of the court, the people working for Uber should be viewed as employees.
Turning of javascript completely breaks so many sites, but it is much, much, much faster to browse the web that way. I run Ublock Origin and it is great, but you are often still paying the javascript price.

Many people simply don’t know about them! I grew up poor and the amount of work that goes into finding and using some services is ridiculous. We bought a house using some assistance programs and at a couple points were speeding across the city to get paperwork in by sone deadline no one told us about (luckily we had a car!).

Not to mention that services like foodstamps can be unreliable… I’ve probably spent hours of my life holding up checkout lines because my card didn’t process…

not having money is one thing, but being poor also obliterates your time if you use various services…which in my experience is worse… you’re always tired and agitated. Someone is always messing up your paperwork, because of course civil servants are often underpaid and overworked themselves.
Pinterest and Reddit are not better these days. The amount of things you can view on reddit on your phone without creating an account or installing the app is dwindling daily.

Every time my wife sends me a Pinterest link I just ask her to screenshot it as I can't see shit on the default mobile page. I don't even know why Google continues to allow them in the results when there is clear-cut policies around showing something different to the crawler than the user.

Ironically, a good workaround is setting your user agent to the Googlebot and suddenly all those modal/nag screens disappear.

Your statement "how hard is this" shows your complete incompetence regarding the backing of anything.

Nothing of value is backed in our world. If a mere 7% of bank account holders go to the bank to collect their money, the bank collapses. They don't have your money, it's not there.

If all owners of gold (gold value papers) today claim their physical gold, it can't be done. There's 400% more value paper compared to the total supply above ground.

If all owners of Apple stock today decide to sell their stock all at the exact same moment, they won't get out the full market cap. Because the entire thing crashed before that. But that won't happen, because the exchange will simply stop the trade.

Which is the same thing crypto exchanges do when things get too heated.
I'm currently typing this on a build of Chromium 93 (official Chrome is at v91) running on Mac OS X Mavericks (released in 2013, incompatible with Chrome 69+), running on a self-built PC with an Intel 4790K. I replaced Mavericks's default AppleColorEmoji font with an updated version from Big Sur, but my system font is of course Lucida Grande. I have a working copy of Widevine.

I would expect most websites to assume that my machine can't exist. But I don't have any problems with captchas.

I read the comment in a different light. He or she is not exactly proud just admitting to the current circumstance. Specifically with this phrase

> so I won't be the one recommending that.
At first glibc's use of TSX/RTM for mutexes was behind a compile-time opt-in, and Intel was hyping up how great hardware transactional memory was, so most distros flipped the switch to enable it. But glibc's use of TSX/RTM for rwlocks was not behind a compile-time guard, and was used whenever CPUID said it was enabled.

I think the first issue was that pthread locks using TSX behaved differently for incorrect usage, so that applications that had double-unlock bugs worked fine with the normal implementation but crashed with TSX glibc. These were app bugs, but a lot of people were unhappy that a glibc update caused their applications to crash, so some distros patched glibc to make time to fix the apps.

Then TSX was broken in Haswell and Intel disabled it, but it was a total mess, such that the bit in CPUID indicating support for TSX/RTM did not reliably indicate support for TSX/RTM (i.e. bit was set indicating support, but any TSX/RTM instruction resulted in SIGILL), so various versions of glibc ended up with various lists of CPU model numbers to determine when to avoid using TSX.

repeat for broadwell.

At this point more distros decided to turn off TSX in glibc entirely. But most did this by just removing the compile-time opt-in, which did not do anything for rwlocks. A couple distros noticed that rwlocks were still using TSX, and patched that too to remove lock elision entirely - but many did not, so rwlocks on haswell or early broadwell would still cause issues.

In my experience, a lot of the time RTM was not useful for performance because the transactions would be too large and abort. It was worse because in these cases glibc would try the transaction again several times before giving up, which could cause massive performance hits compared to just doing the normal lock to start with.

There were errata about TSX in skylake too, but I can't remember if Intel actually turned RTM off with microcode before now or just left it as is because no one was using it.

Eventually glibc was changed to always compile in support for TSX but require a runtime opt-in using an environment variable.

(this is from memory, the timeline is probably not quite right)

EDIT: I had a bit of deja-vu writing this, and it turns out I have whined about this on HN before lol: https://news.ycombinator.com/item?id=22694546
No because the first thing they do is to show you all of the content, ready to be scraped. Then they add their modal and then, after three reloads they store in your browser storage, they stops to show you the content.

So they don’t protect any data, they just leak it all. Then they hide it.
They deliberately make their mobile web experience awful, so I don’t think that’s why (how can you trust a metric that you’re deliberately sabotaging?). I suspect mobile apps just allow for more data collection than web apps.
