I believe that "Success Academy" does a lottery after you apply. This is selection bias again as they disqualify some applicants (almost always by a proxy for socioeconomic cohort).
The "lottery" I am referencing is when students get assigned to any available school which takes public money solely based upon the lottery. A school cannot refuse a student that has been placed into their school by the lottery.
What this does is that it removes selection bias. A school can no longer decline a student simply because they belong to a lower socioeconomic cohort (or use any of the proxy measures that indicate lower socioeconomic cohort--religion, race, ADHD, etc.).
Once you remove this bias, the alternative schools almost always come in looking worse than the public schools. This is unsurpising as the alternative schools are almost always smaller and cannot amortize the fixed costs as effectively.
We know how to "fix" education. You make teacher to student ratios somewhere around 1 teacher (2 teachers if elementary age) to 5-10 students and then place students of roughly equivalent levels together.
Ec2 classic was dirt simple. You basically were on a big public lan it felt like. If I remember right there were some issues with folks running scans / abuse originating inside AWS that felt like got a touch slow of a response - then at some point it all cleared up? I remember hardening internal systems as if the they were public which was a good practice even as vpc arrived. They might have gotten a default public ip as well?
I used google app engine which was orphaned (at least version I tried) so that was a clear contrast w AWS.
[parent comment was edited, it originally mentioned SimpleDB]
Speaking of SimpleDB, we still use it. It's amusing how it's basically swept under a rug at AWS. It's never mentioned, barely documented, but continues to work. It's a pretty good product for what it is - a very simple key/value store where you don't need/want to manage provisioned throughput, costs, keys, etc.
The way they handle SimpleDB makes me respect AWS and feel more comfortable on some other services we also rely on that seem close to abandoned (like ElasticBeanstalk).
However, as a counter-point, they are killing OpsWorks with what feels like a fairly short notice, so I'm also a bit cautious about how long they'll maintain services.
Yeah, I didn’t want to distract but in my use case simpledb was even a fit after first dynamodb release for a reason I forget. Even more they took it totally off marketing after depreciating it but the hammer never dropped! Absolutely love this. The ec2 classic termination was actually a bit surprising in that context.
Re: ElasticBeanstalk - it's just a feeling, and hopefully not correct - it just doesn't feel like it's one of their primary focuses, and seems suspiciously stable overall. There's nothing I particular want them to add, though, so maybe it's "perfect".
I love it, though - it's been a great boon for our small team - allowing for a painless hands-off deployment strategy that's worked great (largely unchanged) for almost a decade.
The public IPs were the big part: if you had the default 0.0.0.0/0 rule allowing SSH, you’d see brute force attacks within a few seconds of launching a new instance.
VPCs gave a little more room to prevent that but the big thing was really better tooling - the average developer still doesn’t think about security enough to be trusted with the EC2 or GCP launch wizard.
I remember this. I don’t remember if it was cloud unit or something else like a pre hardened ami, but basically that - you got hammered in seconds after starting in default config so was good to take some steps right on launch.
Yeah, the official AWS AMIs have had password auth disabled for a very long time but I’m pretty sure I remember some third parties learning the hard way that setting a default password and telling people to change it isn’t good enough.
One thing AWS has done well is charge enough out the gate that they don’t need those “good news” posts where companies jack rates up. Google maps, but many business focused apps I’ve used too end up squeezing ridiculous price increases through. I’ve not experienced that with AWS.
And of all the predations on the net - it’s wild THIS is what the ftc goes after. How about non age gated / warned gore and porn? How is that no a violation?
In this age, I don’t know why browsers don’t simply have parental controls built in. Nearly all adult sites declare themselves to be adults only in their meta data, and if they don’t they can easily be shortlisted as such.
Heck even blocking the top 100 would pretty much ensure children can’t access the content freely.
I remember there being a voluntary rating system for websites back in the 90s. No clue if anyone actually used it, but there was a setting to enable it back in IE6.
The FTC is going after what is made available to them, and the privacy watchdogs said "hey YouTube Kids still has cookies and behavioral ads on it" so they're going to look into that.
My understanding was that age gating was a purely voluntary practice and that the 1st Amendment bars government enforcement of age gating on media. Almost two decades ago California tried to enforce age gating on video games and got shot down by SCOTUS[0]. I am aware that several deep-red states (e.g. Utah) are trying the same thing for porn. I doubt such a thing will get by SCOTUS, not even today's right-leaning court that's in a 'overturn precedent the liberals like' mood. So if the FTC were to start going after YouTube for Pregnant Elsa Spiderman videos they're likely to have a huge legal battle on their hands.
Let's be perfectly clear: if social media companies are required to ensure a 100% success rate with your kids not seeing garbage on YouTube, then they're going to start requiring age verification for any use of their service. Age verification companies are very scummy and, even if they weren't, requiring you to deal with such a company in order to watch a YouTube video is unnecessarily invasive. Practically speaking, if you want everyone to be able to upload video, then the best you can do for keeping kids out of the gore and porn videos is a series of 'good enough' educated guesses. YouTube is not a babysitter.
Unfortunately all the national space agencies seem to suffer from this. Both NASA and ESA also seem to think that people are tuning in to watch the smarmy politician talk rather than the robot making its way to space/landing on another body.
It's also because these agencies are reliant of politicians and government institutions for funding. So there is a balance between "showing what the public actually cares about" and "keeping this guy happy so we can keep up funding / congressional support / etc."
To his credit, Narendra Modi has increased ISRO's budget a lot. Many years they have received more than promised! So he kind of deserves to rake in the limelight.
On the other hand, political speeches on such occasions go down as most remembered historically. The infamous quote "One small step for man, one giant leap for mankind." was obviously said by some politician! (or at least with non-technical motives)
The full version of that section is more amusing but forgotten
>> But why, some say, the moon? Why choose this as our goal? And they may as well ask: why climb the highest mountain? Why 35 years ago fly the Atlantic? Why does Rice play Texas? We choose to go to the moon {applause} We choose to go to the moon... {applause} We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard -- because that goal will serve to organize and measure the best of our energies and skills -- because that challenge is one we are willing to accept, one we are unwilling to postpone, and one we intend to win. (And the others too)
(as spoken and delivered at Rice University in Houston, Texas, referencing the Rice-Texas American football rivalry, where Texas is a 10x larger university)
I think it is a sign of habitual cynicism that you assume "One small step for man, one giant leap for mankind." was said by a politician. I think people feel like they are defending themselves from being manipulated by not accepting anything on its face as sincere. Sometimes a pipe is just a pipe.
That's correct about Freud! I was referring to Magritte, who made the painting "Ceci n'est pas une pipe." By which he meant the image of the pipe was not actually not a pipe. Which means .. well I think you would have to read about it and I am not sure I am using the reference in the right way.
I believe Freud and the cigar is about our thoughts and impulses sometimes not having greater meaning in our subconscious. Magritte is about something different.
No sarcasm, just wondering. Armstrong could have been cancelled or something. I might have missed the Two Minutes Hate [0] when he or lunar exploitation was on.
Could just be a misuse of infamous but could just as well be intended to refer to the fact that Man and Mankind mean the same. You need an article in front to transform "One small step for Man" into "One small step for a man" to refer to Neil himself stepping.
Wikipedia (see elsewhere for link) has good coverage of that. "A" was intended to be said, but when humans say lines like that it is common to miss a word here and there. There is no way to know for sure if he said it and the technology of the time didn't pick it up, or if he misstated his own quote.
Exactly! This has been my own head canon too since like decades! I was actually surprised to read in this thread that "infamous" is a negative interpretation of famous which seems like a revisionist and recent interpretation. The English language also evolves through the ages and so do the meanings and interpretations.
They want to go down in the history books the way JFK's "we choose to go to the Moon" did without experiencing the "mind-blowing" event afterwards that made the speech historical.
I believe the chairman of the space agency also used the Prime Minister's mention of future projects to note it as confirmation that those projects will indeed happen i.e. be funded. That was pretty smart at @ 01:07:00 in the video.
That was very memorable- grainy photos projected on a wall while nasa admin (old white guy) briefed Biden? Jwst had a pretty well planned out program for first images including events and it just got crushed.
That is condescending nonsense. Pretty much everybody would prefer to see rocks from outer space than hearing politicians congratulating themselves and the unity of our country.
Yeah it's more likely this is a case of wants of decision makers being prioritized over wants of the audience. This event is an avalanche of prestige. Of course politicians want to soak it up.
Nope. Same reaction from a wide variety of people including my wife who's not in tech and doesn't know what HN or YCombinator are. She was like "let the team speak already!"
So what you're saying is you'd need to be an uneducated imbecile to prefer politicians speaking to live space footage.
I think you're selling uneducated imbeciles short; surely even they prefer the space footage. Only the politicians doing the speaking prefer themselves.
SpaceX livestreams didn't get super popular for having a politician on them. They got popular for showing exactly what's happening with enthusiastic presenters narrating it.
Most people find speeches and politicians boring. They wanna see rockets flying, robots moving, etc.
The first launch of SpaceX's Crew Dragon with astronauts on-board holds the record for the most concurrent internet viewers on a stream tracked by NASA at 10 million.
Of course if you drop the internet requirement, Apollo 11 still is by far the most live viewed at 600 million viewers.
That makes sense for Apollo 11. I expect that one won't be beat until we land people on Mars. I figured SpaceX had some much bigger viewerships than 10's of thousands. (I've watched several myself.) That number must have been on the more (now) regular things like vertical landing the same rocket for the Nth time! Thank you for the update.
The whole Prime Minister thing was bizarre to me .. He was like on the mission-control screen with his own panel .. it was just weird lol.. Even in the US where our presidents fancy themselves god's.. it still just had a weird perception from my point of view..
But I'm proud of the people that worked on and executed that mission for them. Obviously a moment of immense national pride, well deserved.
ISRO is primary arm of the Department of Space which is headed by the Prime Minister. So in essence, the Prime Minister is the boss. It is not an independent federal agency like NASA.
I really wish to see a lander mission to Venus. Doesn't look like anybody other than Russia has done it - that too nearly 40 years ago. The environment is so extreme that the technology - especially electronics - would have to be radically different. The data is also likely to be extremely interesting.
You can see the onboard camera view in the background sometimes. And the only truly hard thing about this is getting the political will for the funding, so.
I absolutely agree that they should immediately release data & images for more technically inclined section. However the reason for speeches is entire nation is watching this event across all age group, most of them don't understand technical things, I would say even image of moon surface wont connect to most of them. Basically speeches is the way to connect & artists impression images. To give some example, people thing entire rocket goes to moon, one of the politician was wishing "passengers" on the spacecraft, reputed news channel claiming "breaking new" that there wont be delay in landing as if we can push breaks like in car or traffic on the way. So you get the point, to connect to masses they are speaking in language that everyone understand
In terms of being broadly available, most of AVX-512 (ER, PF, 4FMAPS, and 4VNNIW haven't been available on any new hardware since 2017) is available on basically any Intel cpu manufactured since 2020 as well as on all AMD Zen4 (2022 and on) cpus.
I can't speak to being error free or other issues but it should at the very least be present on any modern desktop, laptop, or server x86 CPU you could buy today.
Edit: I forgot to mention but Intel's Alder lake CPUs only have partial support presumably due to some issue with E cores. I'd guess Intel will get their shit together eventually wrt this now that AMD is shipping all their hardware with this instruction set.
Intel seems to be going for market segmentation, with AVX-512 only available on their server CPUs. The option to enable AVX-512 has been removed from Alder Lake CPUs since 2022, and there is no AVX-512 on Raptor Lake.
AMD also keeps making and selling Zen 3 and Zen 2 chips as lower-cost products, and those do not have AVX-512.
With AVX10 intel will make the instructions available again on all segments. SIMD register width will vary between cores but the instructions will be there.
I don't think it was intentional market segmentation, just poor planning: the whole heterogenous cores strategy seems to have been thrown together in a hurry and they didn't have time to add AVX-512 to their Atom cores in an area-efficient way (so as not to negate the point of having E-cores).
>most of AVX-512 is available on basically any Intel cpu manufactured since 2020
That's incorrect. On the consumer cpu side Intel introduced AVX-512 for one generation in 2021 (Rocket lake), but than removed AVX-512 from the subsequent Alder Lake using bios updates, and fused it off in later revisions. It's also absent from the current Raptor Lake. So actually it's only available on Intel's server grade cpus.
>Edit: I forgot to mention but Intel's Alder lake CPUs only have partial support presumably due to some issue with E cores.
The latest Intel architecture (Sapphire Rapids) support it without downclocking. AMD Zen 4 also supports it, although their implementation is double pumped, not sure what the real world performance impact of that is.
There is a huge confusion about this "double pumped" thing.
All that this means is that Zen 4 uses the same execution units both for 256-bit operations and for 512-bit operations. This means that the throughput in instructions per cycle for 512-bit operations is half of that for 256-bit operations, but the throughput in bytes per cycle is the same.
However the 512-bit operations need fewer resources for instruction fetching and decoding and for micro-operation storing and dispatching, so in most cases using 512-bit instructions on Zen 4 provides a big speed-up.
Even if Zen 4 is "double pumped", its 256-bit throughput is higher than that of Sapphire Rapids, so after dividing by two, for most instructions it has exactly the same 512-bit throughput as Sapphire Rapids, i.e. two 512-bit register-register instructions per cycle.
The only exceptions are that Sapphire Rapids (with the exception of the cheap SKUs) can do 2 FMA instructions per cycle, while Zen 4 can do only 1 FMA + 1 FADD instructions per cycle, and that Sapphire Rapids has a double throughput for loads and stores from the L1 cache memory. There are also a few 512-bit instructions where Zen 4 has better throughput or latency than Sapphire Rapids, e.g. some of the shuffles.
That’s a trope that doesn’t bear on the Fleishhacker pool closure. There’s been a shift I think in govt spending from things like recreation to social services. If you took the SF homeless and other social services budgets including state Medi-cal funding that dwarfs recreational spending - and this is a shift in allocation over time. And I thought pools were racially integrated historically and it’s when they integrated genders the race panic stupidity came in big time. Especially in south some bad behavior.
A quick note that the "open source" license they use requires activation and license keys that block feature activations in the "open source" software be preserved.
This license was popular w folks like apollo who arguably hijacked nearly 700 contributors efforts w a license like this. Because they are using it from start at least that won't be as bad
> This license was popular w folks like apollo who arguably hijacked nearly 700 contributors efforts w a license like this. Because they are using it from start at least that won't be as bad
Which Apollo are you talking about? Only one I know is Apollo GraphQL, and their main server package seems to be MIT, so I must be looking at the wrong thing. What's the story?
