If you look at White/Blue/Super funny they will rust. HAP40 is a high-speed tool steel. CPM M4 is a good comparison to it. MagnaCut will offer corrosion resistance that you don't tend to see in Japanese steels. MagnaCut will have better edge retention than White/Blue/Super. Those steels are low-alloy and rely on high hardness for wear resistance. MagnaCut has vanadium and niobium plus it can get pretty hard as well. MagnaCut is so far ahead of White/Blue/Super in this regard. Japanese steels are known for being great to sharpen (even HAP40). From what I have read, MagnaCut sharpens well.

If we say that MagnaCut = stainless 4V and HAP40 = CPM M4, then HAP40 should have some more edge retention but less toughness when compared to MagnaCut. The differences aren't all that great. Corrosion resistance is the real difference maker.
On my MacBook, canonic.com displays a few sentences of text and a few links. To do this, it takes 15 seconds to load a 25 megabyte WASM payload. The resulting page draws all of its content onto a <canvas>, scrolls backwards because it somehow ignores my system's "natural scroll direction" setting, and doesn't let me right-click to open links in a new tab.

In other words, it's a demo of what Web performance and usability will be like ten years from now. Twitter and Reddit are already working on redesigning their websites to incorporate this new technology.

(In all seriousness, it's a demo of a subset of Qt compiled to run in a web browser, and it seems to work better on desktop.)
thanks. i hear you on the desperate employer thing, that got me a job in 2001 working for DigiEffects when their code broke going from iOS9 to OSX
Find file(s) with queries in less than a second? Save the query as a folder and now you have “live” searches?

No.

A subreddit could, depending on it's (unpaid) mods have a wide variety of content. For example /r/WTF content could be funny or shocking. An advertiser on that sub would have to be okay with their content being alongside either content.

Let's say a tumblr site gets tagged as "mature".

That site does not get the expected ads normally seen on a site

That site is effectively invisible to other sites

Why would you buy ads on a site that no-one will see?

Why would you stay publishing on a site where your traffic falls of a cliff?

What makes a site get that 'mature' tag? It could be one post, it could be a series of posts. But that tag stays until it manually removed.

When you are running a site that has user generated content there are two alternatives:

- Being clean

- Being seen to be clean

Tag filtering helps the latter.
I've been in this position myself (as someone with an engineering background!!), and it's a matter of effort vs. return.

Far fewer customers care about a website than an active social media profile, and the effort required to maintain them, secure them and set them up is orders of magnitude higher.

If you're a growing small business, there are typically much better ways to invest your time.
Nobody uses that symbol after grade school.
No wheels, except on the East Coast, but West Africa had, for example, drum telegraphs and (probably independently invented) iron smelting for 4500 years. Heliocentrism was mainstream in Mali centuries before Galileo. The Americans probably learned inoculation from Ghana. Coffee, irrigation systems, dams, aqueducts, terraced farming, megalithic astronomy, etc.

Except in telecommunications, surgery, and metallurgy, subsaharan Africa wasn't ahead of Europe, China, and India even before the early modern ramp-up in the slave trade, but it wasn't nearly as far off as you'd extrapolate from looking at the ruins after 500 years of enslavement and colonialism.
Have to admit, my first thought was "lucky them".
Fascinating.

They mention in the paper that the Dark Ages power spectrum would require a 100,000 dipole antenna array, seems like we are far from that.

It's pretty crazy that we allow ourselves to be bombarded with the psychological attacks that are advertising. Ads use pictures of food or sex appeal that manipulates our lizard brains or social attacks to convince us to buy products we don't need. If you pay close attention a large percentage is for negative sum products like unhealthy and addictive fast food.
It took me until the following passage to realize this:

> As my regular readers will by now, I think that a massive deficiency in religious literacy is causing confusion. We have an inability to make sense of new developments like Bitcoin because our fundamental nature as religious beings — homo religiosus — is being denied. If we recognized and embraced it, who knows what Renaissance of reason and innovation we might see?
Indeed, this is relying on the optimizer’s cardinality estimates from previously collected statistics. These are notoriously inaccurate across all DBMS’s in even marginally complex queries[1].

They’re obviously better than nothing when making planning decisions—correctly estimating A > B is useful enough even if both are off by large factors—and maybe for this application it’s effective enough.

For the DBMS I work on, an alternative solution would involve bitmap indexes for each possible filter field. These are compact and can be logically combined and counted at rates of billions/second via SIMD, even without HLL or other estimators.

It’s incredible to see Lana be handed millions of dollars to make a film and they bomb every single time no matter how large or spectacular. They just keep giving her money. It’s amazing how she makes the same mistakes every time and never seems to learn or gain any self awareness. And it’s amazing to think it all began somehow with the greatest movie of all time.
It's mirrored by Hungarian nationalism. The Hungarian minority has a party in the current government coalition. It's also not their first time in a coalition. There were tensions in the 90's but in general they're well represented and treated. They've got state education in their own language, schools, Hungarian departments in several universities. Also the Romanian far right was pretty much off the radar after admission to the EU and until last year. I believe it's actually Russia backed and has brought ultra nationalists and anti vaxxers together, pushing nationalist, conservative and eurosceptic rhetoric.
Personally I wonder whether anyone actually used log4j willingly or just because its generally used by all the apache projects and they wont start without it.

With a healthy dose of "use the latest versions" mentality.

I checked back and all my java code was still running log4j 1.1, and removing it has been on the todo list ever since it needed linking.

You should be checking all your 3rd party source code, "capabilities" wont get round that, the number of applications that dont need network access these days is as good as zero.

The first batch was given to smaller makers, often custom makers. Right now, Tactile Turn is offering a couple knives in MagnaCut (change the option in the drop down). I've seen people say they have used up their MagnaCut already. The steel will probably trickle into the market.

Spyderco announced that the Native 5 Salt will come in MagnaCut. No date has been given for that.

I spent ~10 years in the rental car business (although the very very high end of it.) Let me say, it's a weird business with LOTS of quirks.

Here's one: One of the biggest frustrations people have is that it seems impossible to actually get the car you reserved. Seinfeld even has a whole schtick about this - why is it called a "reservation" if it's not actually....a reservation?

Reservations never work because the rental car companies don't enforce them. You can book any car with any rental company and cancel up until the minute of the rental or just not show up and there's no penalty. (Everyone forgets this part.)

If a rental car company actually treated reservations like reservations, then they'd hold your Toyota Camry for you and not give it to someone else. But then when you decide not to show up for your rental, the rental company would be stuck because they planned for you to show up and you didn't.

So they have two choices: Either assume there's only an X% chance you're going to show up and use that to roughly plan fleet availability for that given day (the current state of affairs which results in your not getting a car you reserved when X+10% of people show up that day instead of X%), or start penalizing people for not showing up so they can actually honor reservations.

And why don't they do that? Good 'ol competition. Everyone is afraid to start enforcing reservations because if Hertz does but Enterprise doesn't, people are going to book with Enterprise ("Book w/ us and never pay a penalty when your plans change!").

You will notice that they are tip-toeing into this -- lots of companies now offer discounts for pre-paid (non-refundable) reservations, but the no-penalty-for-no-shows-pay-at-the-counter option is still there. And until it vanishes, the reservation issue will still be there.
Ah, thanks, that makes sense.
I don't know much about the company, but don't they run Wordpress.com? I think I've seen some wild stuff on subdomains there, do they do similar filtering on ios for those sites?
Great work, seeing news i wouldn't see otherwise.

Where are the votes coming from? Are they actual votes? Since i don't really see a pattern on big upvotes: catholicism, a city in the US and Indonesia.

Not really sure about the correlation about your current audience. It seems a bit off, except if it's an indicator from the site your pulling it from.

> If users ... want to opt into using a new less-broken thing, they can always do that

Users don't necessarily have that much agency. The most successful and powerful businesses don't need to satisfy user preferences because the users are FORCED to conform THEMSELVES to the constraints imposed by the business.

I've always found car rental to be the least competitive market out there.

My car cost me £800 approx a year ago. I spent £150 on new tyres and I've since driven it almost 10K miles without much other than the odd oil change and brake pads etc.

Add on insurance and tax and it'd be about 14-1600 annually if it exploded tomorrow.

That's £5 a day. But there is literally nowhere I can rent a car for that. I can't do 10, 15, etc.

And that £5 is an overestimate of the cost based on it having a residual value of 0 after 1 year.

Mainstream car companies universally rent out cars that are far newer than most cars on the road.

I get that renting out absolute bangers might be hard to manage, but surely there's a middle ground here.

I would sell my car and rent if I could do so for less than 2x the all-in price of my current one, but I can't even get remotely close.
Thanks! I'm not the one who shared it here, but I'm the one who wrote the article. It was a blast to play around with Sam. I hope to play around with some other Plan 9 utilities as well.
Pretty sure you don’t live in Central Europe or areas like northern Michigan?

There are weeks with zero direct sun, just low cloud cover, scattered snow, and cold cold cold.

I was in Michigan once when Lake Superior froze over, shore to shore.

Unless the place is so well insulated you can keep it warm purely with body heat, you need supplemental heating in climates like this. The sun is not always shining.
> Or just buy their insurance

Note that many credit cards cover your insurance.
Static ads I can look at or ignore at if I so choose, both on the web and on the street. For reference, just some decades ago static ads in, for example, a computer magazine used to be as much valued content as the magazine articles themselves.

Ads become a problem as soon as they become interactive, illuminated, or moving images. Those remove my option to consume the ads at my own pace and choice. Instead, they become attention magnets primarily to be fought against.

Just as pop-in ads or flashing/screen-estate-hungry ads are bad on websites do large, bright digital advertisement screens make a horrible streetscape and in public transit video screens totally kill your ride. You can no longer walk or sit in your own thoughts as you're kept occupied to avoid looking at the flashing, moving footage.

Google search still mostly does ads right. Not only are they sometimes even relevant but firstly they don't stand out so badly that I'd refuse to take a glance at them.

(Not that I ever click on any of them because that would support the ad-business. If I see something interesting I open an incognito window and browse the corresponding company's site directly and look for the bargain/offer - they might still be able to track me, even if partially, but at least there's no direct link via the clicking the ad.)
There's an RSS feed. There must be some services out there for automatically checking an RSS feed and sending emails, right?

I don't think this is true, because the Reddit iOS app would've been shut down ages ago if it was.
There is a large difference between "them" having to m2m smtp sessions to intercept emails versus directly sending the emails through them.

Besides, metadata is probably already more significant than the message contents and encrypyion solves nilch there.
How could it not be completely different? We both came to HN. We saw this article about advertising. We clicked the "450 comments" link because we wanted to see what other people were posting. We wanted to participate. That's what we're doing right now.

I didn't pay money to put this comment on your screen to make you read it every time you try to do anything on your phone or computer. No, we're the ones who came here to talk about this stuff. Speech is not advertising.
Very interesting project. What I don't quite get is if you can calculate the state after 100 steps in one go what would make you select exactly100? Why not select 1007 or 10 million etc. ?
That percentage is far too low, any ideas on how we increase it?
http://joeduffyblog.com/2015/11/03/blogging-about-midori/ sounds relevant as what sounds like a contrast in that space.
Yeah I totally get it. It's just not nearly as relevant for my industry (web dev) as it is for actual rocket science, for example.
Has your life really changed that much since computers? I guess I have a different career, but in most respects it's about the same. These things are addictive little tchotchkes I can't seem to put down. My wife was just complaining about the Nest products I buy and then never take out of the box.
Dostoevsky is one of those authors for me whom I just really cannot stand when reading the book, but there are always quotes from them and critical interpretations of them that I find absolutely amazing. Hemingway is the same, except for The Old Man and The Sea.

Honestly, I prefer my writing to be opinionated. Every author has an opinion, which means I'm going to waste energy trying to decipher their opinion from their facts if they present too neutrally.

One game you are unlucky, another one you are lucky. I've played hundereds of BW 2p matches, and lost/won only due to extreme run of good or bad luck maybe in 3% of games. Just move on and play the next game. Or play chess.
but doesn’t the printed text fade away before then?
Whatever language is spoken, it’s always a dialect of some parent language. Even preferential versions of the language, like “the Kings English”, a.k.a., Received Pronunciation, is still just another dialect that happens to be preferred.

You could just as easily have asked him what dialect of German that he spoke.

This happens in languages that do have an official version, too — like French. There’s an official dialect that is defined by L’Academie Française, and there’s everything else. But they’re all still dialects.

Robust printer support and color management.

Which at the time would have been super super duper important for the just-hanging-in-there Mac user base. (I was one of them. It was just hanging in there.)

> Every time you say something like that, imagine that someone whose sense of injustice is opposite to yours is using it.

This line of reasoning only makes sense if you think that moral positions have no qualities other than how strongly people hold them. If, on the other hand, you believe that two people can hold two opposing moral positions with equal strength, and one of them can be correct while the other is incorrect, this line of reasoning doesn’t make sense.

Of course, this was obviously Tutu’s position. Tutu probably didn’t think “before you go and help the mouse, realize that doing so might be just as upsetting to the elephant as your neutrality would have been to the mouse.”

> Price signals are an important part of ensuring that resources go where they're needed, but this also sort of assumes that everyone has an equal capacity to pay.

Right, but it's not claimed that price signals is some all-powerful force to drive behavior. It just ensures "resources go where they're needed" in aggregate. Well resourced individuals can still use their money to override that as they see fit.
It's surprising it's only 3 years, and that is for men. For women it's even less. Most people if surveyed would guess figures like 10 years or more, but as it turns out, obesity just is not as big of a killer as the media hype would have one believe.

I know someone who exploited this and would just keep a reservation handy in their city in case they needed a car, cancelling at the last minute. It was basically a zipcar for them with no membership fee.
There's what I think is a similar concept in Java called security contexts. I've never encountered it actually being used, and it just tends to get in the way, like you said. These strike me as similar to SELinux in that regard.
If your language is capable of expressing "this part of the code can't access the network", in a general way such that networking is not some special snowflake that's baked in, then you've created an effects system which is likely to be useful in many, many other contexts for other things you want to assert without having them supported in the OS. (For example, "is this code async", or "does this code print anything", or "does this code have any side effects", or "does this code throw", or "does this code allocate".)
The article sounds good. It depicts how current mainstream business models collect data and maintain control over their users, in a way, it seems it will legally challenged.

But wait a moment. It offers, in exchange, and in an indirect way, but as the author being the founder of Ethereum, the decentralized app business model, where app developers / users must pay a fee to participate.

So the current choice is: Go develop a business the classic / mainstream / centralized way, and do, or do not harm by collecting data and control the users. Or, create a decentralized app, where the first thing, for you or your users is to "Get some ETH".

No thanks. I don't think the answer for what FAANG did wrong is me / my users to pay a fee to develop / use an app. There should be a third way.
Per TFA, it is to an extent? The author briefly discusses a computational search of the design space, and uses that data to encourage the partner company to make a batch of the steel.

That said, simulating material properties from atomic scale principles seems nontrivial compared to predicting them given observed parameters and properties of other alloys. I’d be interested in more informed comments on that possibility!
