> Wood’s flagship fund, the ARK Innovation ETF, had lost roughly half of its value over the prior year, as its aggressive bets on hot companies from Coinbase to Robinhood and Tesla had melted down amid a bear market in tech stocks.

It's important to note what this really means. You can have 4 years of 20% returns and if the last year you're down 50%, you gave back nearly everything you've ever made, assuming you had no new money come in those years, otherwise even more. The max drawdown is whats important. You can almost always make money writing out of the money call options, except the one year where you give back everything you've made and then some. As expected:

> Her ARK Innovation fund, often known by its ticker as ARKK, returned some 157 percent during that first year of the pandemic, compared to just 18 percent for the S&P 500 as a whole... Wood’s fund is now exactly where it was in March 2020, meaning pandemic investors who bet on her have now round-tripped all the way up and all the way back down. Adjusting for inflation, they have lost money.

Cathie Wood is one of those investors that just makes directional bets, in her case high growth tech stocks. They happened to do well last 5 years or so, so it appears that Cathie has done well. But same as someone who just plowed a bunch of money into Bitcoin in 2012, it doesn't mean you're a good investor or you have anything interesting to share today.

I read her Twitter occasionally and found her very unimpressive. For instance, she made some uninformed comments about "velocity of money" decreasing and that's the reason we won't have inflation (this was during the "transitory" phase of inflation denial). Then she had some ridiculous examples of things actually going down in price like AI training costs, which should balance things out. It was so comical it could have been on the show Silicon Valley.

Apple App Store appears to be widely removing apps that still work, but have not been recently updated, like native apps and PWAs, so treating better would be very welcome:

This kind of guidelines also kind of do not treat PWA style apps well, or could even prevent adding app that is similar to another app already existing at App Store:

I don't want to deal with maintaining another OS, so I'm perfectly happy with them maintaining it and making updates easy.
I have both Pi Hole and browser ad blocker plugin, the biggest problem is, sometimes a website does not function well or everything just loads extremely slow, I then have to spend some time debugging my network to know what is going wrong.
Well, the potatoes are pretty much free if you have some dirt to plant them in.
There is no anonymity if you connect to 4chan using a Silicon Valley designed processor.

The "facts" that these shooters are fed are highly tailored to what they are predisposed to believe already, because the ones posting have complete surveillance of everyone (including of you who reads on HN) and know exactly what to post to create a shooter.

Silicon Valley has blood on their hands. 4chan is just one of the places used for these operations.
> based on watching protests and other political activity over the last few years, it's substantial

I’m not convinced it isn’t just performance art or clever meta-commentary or a joke for the in-person protestors as well.
Would it not be in Intel's best interest to have popular compilers be able to squeeze the most performance out of its own line of CPUs?

I'm wondering how the incentives play out to keep this stuff private?
Ask HN: Is Security Possible?
I've been working on a web app for the past two years and keep having the uneasy feeling that security-wise all I'm doing is adding a few "rooms" to the house of cards that is today's software and network security.

Would it be possible to host a single _bit_ on the web that I KNEW could not be hacked, exploited, MITM'd?

So much of civilization is now networked, critical infrastructure, even nuclear power plants. With the state of our security capabilities, this seems unconscionable.

I'd like to be part of building something that has actual security---not the whack-a-mole that is de facto for every major operating system, library, database, API, service, device, CPU architecture, programming language, etc.

Is security even possible?

I've learned Rust, which can solve or seriously reduce the risk of _one_ class of security holes. But that's at best a constant-factor improvement---even if all software were competently written in memory-safe languages, the threat surface would still be unfathomably vast.

What are we even doing here?

P.S. I know this is a bit hyperbolic but... there's got to be a better way?

P.P.S. The lack of security also seems to be the main threat to the Internet's end-to-end principle, which has previously been the most empowering thing about this global network.

Uh no, I mean the doctrine of code review in general needs to be put on a diet.

I'm definitely opposed to everyone sitting around synchronously nitpicking everyone else's code in enforced meetings, but I wasn't considering that.

Onboarding new devs is where code review and pair programming is obviously useful. And honestly I've seen it go both ways, where onboarding a new dev was an opportunity for the old veterans to learn some new tricks. If code review for new devs is just beating them into submission with your own code standards for the sake of your own code standards, then it becomes more of an ego-flexing exercise.

But day-to-day it can get very repetitive and if I'm looking at a PR by a dev who has been around for a long time, doing work which is repetitive work that we've already beaten to death how to do it all correctly, I'm going to give it a very thin skim--that would probably absolutely horrify people who deify code review--before just approving it.

And most of the regressions that I've seen shipped went through code review and everyone missed the edge condition, and done 100 more times everyone would have missed it again, and nobody would have seen the deficiency in the tests. Donald Rumsfeld's unknown-unknowns.

This obviously doesn't apply at all to externally-contributed code to open source software, because you can't really trust external contributors to think through all the edge conditions, you have to assume they're operating in "just-fix-my-bug" mentality and the fix may not be correct or may not be (adequately) tested. That's where you need to be very defensive and need to have your "steward of the codebase" hat on. But for teammates that you've worked with for years, everyone should have their own hat pretty well-developed and its good for velocity and reduction of frustration to trust them a lot more.
>they do have a fairly uniform community.

I strongly disagree with this. Although there is some minor overlap between the different boards or *chan sites, the community is hardly uniform. There's a huge difference between the likes of /pol/ and /lgbt/ or /o/ and /b/
I move a lot to different cities, but was able to come to a similar conclusion in central FL in that every house older than 1980 or so had a wood burning fireplace. The thought was so gross to me even seeing them...it rarely got cold enough to even warrant heat. Of course, it was very rare in new builds, and even then usually just the decorative kind.
Looks like someone wrote pretty good parallelizable code on the original question, here: https://stackoverflow.com/a/72333152
On the outside, VC should theoretically be about value investing in the best startups that have sound fundamentals and can grow. Practically, when the market is optimistic and everyone wants to invest in high growth startups, the game can become about "passing the bag". Invest in a company at a low valuation in their seed or series A and wait for a later stage investor to come in and be the one left holding the bag. Ideally, the startup generates enough hype to IPO and then all the investors have a successful exit. You can see this trajectory with startups like WeWork.

When the market is not that optimistic anymore and people are in conservation mode, there's no one to pass the bag to anymore so VCs have to appropriately adjust which businesses they are going to invest in and the valuation.

This is why hype, signaling and FOMO plays such an important role in fundraising. It is about whether the startup can generate enough promise to convince others that they're a high growth investment vehicle and not as much about whether they are profitable in the short term.
Much like the re-invention of "fogbank" for nuclear weapons.

I love ad blockers such as this and uBlock Origin, they truly will make your experience cleaner than even offering to pay for services will, but you have to be careful to not fall into the "wow, <x> percent/count of my requests were for ads that's crazy!" trap when looking at their statistics. Often when services cannot reach something they are set to retry so it's very easy to turn 1 actual request into 100s of blocked retry-requests in statistics panel.
During lockdown I found that a bag of ‘meme stocks’, like Gamestop and AMC was outperforming the ARKK ETF, and still does so in the current downturn. I don’t quite get how a huge ETF could perform worse than an obviously stupid investing strategy…
memcpy is more like copying a single line, to copy a rectangle you need to call it in a loop or use specialized blit hw/sw.

How is MLIR different from LLVM IR?

And tile/block processing is not that novel for generic compute, graphics use it for other reasons - mostly how the pixel data is in memory and how the pipeline scales with tile size.

Susceptibility is a big factor too. Seeing something mysterious on the internet is one thing, but believing in something that has no factual or verifiable basis is quite another.

So a followup question is, why are so many people susceptible? It seems to have something to with making sense of the world when you feel like you're being lied to all the time, and I totally get that part, but I don't get how these conspiracy theories help with that.

It would be one thing if it was just a handful of people, because there's always a few people who will believe anything, but it's a lot more than just a few in this case.

In this particular case, true, but the design of these also lacks feet, so the leverage of the rack works against it, rather than in its favor.

I can't find any source of Laurie Bream in Silicon Valley being a caricature of Cathie Wood but the resemblance is uncanny.
Pinhead & Hexlox barely say how they work or offer any instructions and they're also quite expensive compared to cheap bikes.
Cathie Woods has no idea what she is doing. She rose to prominence betting on tech stocks during the bull market and doubled down on them despite most being grossly overvalued even if you assumed they would double or triple in revenue. Now we have entered a bear market and all of her gains have been erased.

Just a few months ago prominent investors were on the record saying Warren Buffett style value investing is outdated and dead. They were and are wrong. Value Investing might not realize huge one year gains, but it also won’t see all of those gains erased at the hint of an economic downturn.

I've been to a lot of protests of all types [to be clear, as an observer, not a participant], including far right and antivax protests where many QAnon types were present, and I can say without any doubt that most of the people involved are sincere.

I also spent an inordinate amount of time watching protest/political live streams in 2020 and 2021, which further reinforces this.
in japan bikes are stolen once in a while by drunk salarymen who dont want to wamk to go back home. so not 100% safe but fairly safe. also all bikes have a registration number so you eventually find them.
First, I'd remove the email from the editorial team at the bottom. It feels like doxing. I understand that anyone that is not a moron can find those emails, but for that reason I think it's not necessary. Moreover, making morons fail to get the email is a feature.

I tried to read the "Smoking Gun". It's a links to a viewer, so it's not necessary to download the file.

The first section 2 about not publishing a clear script of how the author published the data is so common (at least in other areas) that I'd not bother mentioning it. It would be nice to have that information available (at least in other areas), but the hard true is that in each paper (at least in other areas) you must cross your fingers and try to guess what the author actually did.

Section 3 and 4 are about discrepancies with other source. Most errors look small and are probably not relevant. I'm not surprised. It's not ideal, but I've probably seen worse cases (at least in other areas). Try to focus in big error with big effect. This sound interesting:

> Peculiarly, the mere change in registration cutoff date tripled the effect magnitude for White voters living
within 100 meters of demolition projects, from slightly below -0.05 (decline in turnout by 5%) to around -0.15
(decline in turnout by 15%).

I don't understand the section 6 about other works by the same author. It's common to republish the papers as book chapters or vice versa.

Perhaps there is a smoking gun there, but it's surrounded by a lot of small complains that are (sadly) usual and no one will be concerned by them. Try to find the most clear and most big problem, and isolate it.
it lagged the qqq too. at best it generates beta. no alpha.

I'd take your comment with a much larger grain of salt. Be aware that all of Sequoia's existing VC investments are getting marked down drastically as well. Private company valuations don't just magically stay at above market levels when the public markets go down.

The addition based version should be hand vectorizable if you do the math to figure out the increment based on vector sizes.
This is equivalent to an association list (aka alist) which is a technique which goes back to JAM.

(define xs `(foo (bar ,1) (baz ,0)))
(second (assoc 'bar (rest xs))) ;; 1
(define (prop xs k) (second (assoc k (rest xs))))
(prop xs 'bar) ;; 1
Here in Spain this is a bit of a thing. You can get a three course meal for a fixed price of around 12 euro. Usually about 3-4 choices for each course that change each day. Pretty much every restaurant does this.

Problem is it's only for lunch time and eating the big meal of the day at lunch doesn't work for me :( I end up being hungry at night and having 2 big meals. Whereas a small lunch doesn't bother me.

Journalists do this all the time now. They coordinate reporting to manufacture controversy that will hopefully shame advertisers into censoring opinions they find disagreeable.

Most of the time it's a massive cope pulled out of their asses in lieu of any real solution to a societal problem. They've accepted the fact that Americans will not stop mowing each other down with military grade weaponry and have redirected their impotent rage towards cheeky memes instead. I'm sure some French motherfucker has written reams on this sort of phenomenon.

I dunno if it will work on 4chan though. It has always run on an absolute shoestring budget and is not beholden to any demands to grow.
Would you care to share any details on how you made it?

I have a back-burner project to make one out of hardwood on a CNC, which potentially requires a custom generator.
So many people got burned by this, same for chamath's spacs. Index funds are boring but they work.
I'd honestly never given much thought to the ownership of 4chan. I think mentally I'd put it in the same bucket as a site like The Pirate Bay, in that the ownership almost doesn't matter. Domains can be seized but the software is out there so it's fairly resilient in that it's easy to set up again.

But this is fascinating. Why a Japanese toy company is a part-owner of 4chan is both something I never would've expected. Nor would I have expected it to have various US offices. That could well be its undoing. Given recent events it may finally have reached the attention of the NY AG (mentioned in the article), the DoJ and Congress.

A toy maker linking themselves to a platform known for its links to the illegal (including child sexual material) is wild. Why is there no effort to shut that down? Does this say something about Japanese culture in that if a US company had similar links there'd be a public outcry?

And why does the US government, who went to extraordinary lengths over Wikileaks, apparently had little to no interest in this until now? I know that Federal agents frequent the site. They're called "glowies" in 4chan-speak but unravelling a corporate structure is something the US tends to do when it suits it.

As for 4chan's role in radicalization, I can't help but point out that you cannot radicalize someone to views they weren't already predisposed to believe. The article mentions an incel who frequented /r9k/ (which is the first I'm hearing about this board) and obviously there are the white supremacy links to /pol/. There are base attitudes in both cases that are reasonably normalized.

It's why countries like Saudi Arabia, Iraq, Iran and Afghanistan create Islamic extremists rather than any other kind of radical: there are prevelent societal (and understandable I might add; not that I'm justifying extremist violence of any sort to be clear) anti-US attitudes in those countries.

Likewise QAnon became a phenomenon because it found fertile ground in existing attitudes with a significant portion of the population.

At some point you have to address the underlying attitudes that lead to radicalization.
It was really strange to watch my family fall into QAnon. I've been on the internet since the mid 90s. I remember when 4chan came along, I remember it being just a silly place. I remember when Anonymous started there too. But when my family got hooked it was weird they had been watching Glenn Beck and Alex Jones and other rightwing figures. Then I remember my step-mom telling me she wanted to join Anonymous and become the biggest informant ever. I was taken aback. I didn't understand where the conjunction between right-wing media consumption and a quasi-hacker group intersected. This was back in 2014 mind you. I took her down to my computer and I showed her 4chan and a few other places and asked her is this what she was talking about when talking about Anonymous. She had no idea what I was talking about. She lost her mind, quite literally, a little bit later. My dad filed for divorce and they separated. But he continued on with the Q shit. I don't talk to him anymore, he's a fucking stranger to me these days.
Much of the QAnon mythology incorporated conspiracy theories and beliefs that already existed within the right-wing and Evangelical communities. I think it tapped into the populist zeitgeist of Trump's base - which was already deeply conspiratorial - and crystallized all of those inchoate fears into a single narrative, promising vindication, redemption and cleansing. I don't think it can be separated from the greater global right-wing populist shift, or the phenomenon of "post-truth" reality, whereby people tend to live in self-reinforcing bubbles of subjective reality manufactured by news and social media, rejecting the mainstream almost by reflex.

I doubt most people who fall into QAnon know what 4chan is or even care. It was a parody that was so on point, the people it was mocking just saw it as a revelation.
Ah, that makes more sense. The connection between EE degrees and jobs seems tighter than in computing.
Yeah. If someone wants to do a levered bet on tech, they should. This is essentially what Cathie Wood is selling. So let's just drop the BS.

Peter Thiel gave a speech at a Bitcoin conference a few months back where he explained Bitcoin price movement resembling a levered tech stock. And I'll say, it makes a lot of sense and dispels the whole idea of Bitcoin being an inflation hedge.

I like it! I'm reminded of Apple's attempts at localizing AppleScript.

In addition to the standard English-like AppleScript syntax, Apple also developed [1] localized dialects including French and Japanese, as well as a "professional" query language syntax:

English: the first character of every word whose style is bold
Japanese: スタイル＝ボ-ルドであるすべての単語の最初の文字
French: le premier caractère de tous le mots dont style est gras
Professional: { words | style == bold }.character[1]

(Any transcription errors are mine.)

The dialects apparently shared a common internal representation so you could write a script in one language and then view/edit it in another (of course comments would still be in the original language.)

From an interesting retrospective by one of its designers:
