The VAM metric (which is not very complicated) measures teacher performance by excluding student quality as a causative factor.

If you have low quality students, who are only expected to score at the 25% level, and you boost them up to 35%, you win. If you have high quality students expected to reach 75%, but the only achieve 65%, you lose. Do you believe it's really that hard to predict that Asian kids in 2 parent $250k/year+ households will score higher than black kids in 1 grandparent $10-20k/year households?

If you truly believe the effects of education are immeasurable, perhaps we should stop wasting money on it. We don't spend $859 billion on homeopathy for much the same reason.
If your argument is that we should purse some kind of standardized metric for teaching effectiveness, and that it might take the form of a standardized test, I'm with you.

If your argument is "nothing could be worse than the way it is today", I strongly disagree. More than 70% of Americans are satisfied (or better) with their own local school. High-stakes testing can easily make schools worse by disrupting curricula and damaging incentives for teachers. If we're going to focus our efforts on the school systems that are in crisis, there are probably better interventions.

Measuring teacher effectiveness is a real problem that needs real work, but in the interim, primum non nocere.
I don't think backing up the entire db to a laptop is a good idea, since laptops can get both lost and stolen. As somebody who uses the service, I am not super-comfortable with knowing that a full copy of my account and everything I save is sitting on a laptop somewhere.

It would be much better if these dumps were made to S3, or somewhere else that is actually in a secure datacenter (and a step that includes the word 'encryption').
Copy a string in one line:

while (*dst++ = *src++);
POTENTIAL SPOILER

You only have to think in terms of permutations, which always break up into cycles. How is this especially hard?
thats why I never have a DELETE in any query, only UPDATE and a state field (ie. deleted)

performance advantage here as well since indexes aren't rebuilt and no table lock
This is the dumbest and most dangerous idea I've heard in a while. Go ahead and vote me down, but I hope some on this site have the common sense to see how bad this idea is. This is essentially welfare, and in the US, we've been down that road and we know exactly where it leads.
...precedent.

"You keep saying that word. I do not think it means what you think it means."

As terrible as I, too, think this decision was, it was a decision by a trial court judge. "Precedents" don't attach to trial court decisions, only to appellate court decisions.

If Restis appeals, and the dismissal is upheld by the appellate courts, then there will be a precedent, with everything that implies. Similarly, if he appeals and the dismissal is reversed, a much more favorable (to your and my tastes, anyway) precedent will attach, which can be used to argue against any other attempts to toss suits to which the government isn't even a party on the basis of the State Secrets Privilege.

For the moment, however, this is an "isolated" incident, and can't be used precedentially in any similar cases.

EDIT: Yes, follow-ups, there are other definitions of the word "precedent". In the discussion of a legal decision, however, the legal definition takes ... well, precedence.
It wasn't random stuff pulled out of thin air -- it's a well researched paper that cites 158 academic sources. Of course it will seem weak if you will dismiss its arguments and evidence out of hand rather than critically engaging it. If nuance is what you want from this site, then try it yourself, yeah?
Totally agree, it could have gone quit a few ways from the start of it.

You were apparently more right the first time. -X establishes an untrusted connection, subject to limitations. -Y says "trust me, no limits". -Y is the less safe option.
It is common mistake to count all countries with names ending "*stan" as one totalitarian region. I live in Kazakhstan whole my life (30yr) and I or all my friends hadn't any issues with police. We have one big drawback, it's called corruption, but all countries have to pass through this desease.
So true! Employers are investing so much time in the preliminary recruiting, filtering, and scheduling- by the time a face-to-face interview comes around you can guarantee they are interested in you. Candidates can make their job much easier (and perhaps land the gig) simply by anticipating their questions and concerns. Come prepared, ready to prove your qualifications and all their questions just might go out the window anyway.
I doubt anyone read the title, and then upvoted, because they assumed it was an article about how psychedelics held the key to humanity's survival.
Parking-- problem is, when you have to source it yourself you can end up working for a company where there is not enough parking in the area. Spent a year dealing with this, couldn't get a spot to rent on a monthly basis, there was more demand than parking supply in the area. The company got a deal on the office rental and so ignored this. Them having to source it forces them to take it into account.

Convenient to transit plus a transit pass can work for some employees and having that as an option would work for me some of the time. The situation that caused this to go on the list was one where there was no convenient access to transit and I lived in a place without access to transit. A better phrasing would be "have transportation and parking if necessary be convenient and not a significant distraction from work."

I worked with Bezos dealt with him on tickets etc.

1 year cliff is terrible when you get "laid off" in month 11. There's absolutely no reason for it, really. It's not like it takes a year to figure out if an employee is any good or not. It's just greed. It may be "standard" but so are open office plans and I'm no longer interested in "standard".
Thanks, will keep that in mind, google does not seem to be allowing me to pull most visited website data from the history, though :(
> There is a brief period in time when data is present in the clear in memory - when it's used - but nothing can be done about it, short of moving the code to some kind of protected processor.

`mlock()` can be used to prevent the memory from being paged out, but the DMA issue itself isn't something that can be (or should be) solved in userspace; if someone can do DMA reads/writes, rewriting any code or data, there's nothing an application can do.

Catullus is the greatest, though.
You're assuming that the time/money spent working on web literacy at Mozilla can just be taken and thrown at Firefox to make it better. I disagree, and think that web literacy is a good direction to put some effort towards as it relates pretty directly to our manifesto.
Plenty of languages are commonly used for writing backends. JavaScript may be more popular for backends than Python for new projects these days. The point is that JavaScript, CSS and HTML are native web technologies, Python is just one language choice among others.
I would put it more on the fact that attacking a foreign government is kinda usurping the role US government and they won't take kindly to that.
Anyone used Racket AND clojure in production? Any first hand experiences? We're looking to add another language/environment to our, currently RoR+Postgres stack, and have a soft corner for lisps.
If you don't mind your soul, and are only after money, do COBOL instead.
So it's either all or nothing? It's possible to concede some privacy in some aspects of work/life while trying to retain it in another. Even though you have a Github account doesn't mean that all your code is on Github. You might not have remotely close to all the work you do in an editor on Github, at least if you're the kind of person who's more comfortable in your favorite editor than in a word-processor. People have been power users of editors for decades without needing the cloud or a remote, third party service in order to use them.
I disagree. I have seen very little in any religion that puts them in direct opposition to science. Rather it's peoples interpretation of both that seems to create so much conflict.
How much value would you get out of speaking if it were free (assuming they pay for travel)? If you told them a price and they said no, would you be okay walking away from the opportunity?
This is an age-old problem -- see Romans 7.15: "I do not understand what I do. For what I want to do I do not do, but what I hate I do." (http://goo.gl/p4hl) [EDIT: Corrected the chapter from 1 to 7]
"Leave the gun. Take the iPad."
Ah, that actually makes a bit of sense -- but what about quality of solution? like if they see a second answer and if they decide the first answer was better?

This model actually seems pretty viable, my idea was actually related to real-time translation apps, so it's a little harder (for the user) to establish which is better or not, but if it's a program, then they can definitely check if it works (at least) right away (and probably with some good google searches or even an explanation, find out what the person did that was different/special/good)
100% Nerd Vitamins, thank you for making my evening better.
I don't see an issue. If a browser wants to create a websocket connection, it will always create a fresh connection and do a HTTP/1.1 upgrade. Because that's the only way how websockets are specified.

On the server side most things are handled in the low-level HTTP handlers. There (e.g. in Netty/Jetty and Co) one needs to care about ALPN negotiation, websocket upgrades and Co. But higher up (J2EE, express, etc) things are mostly about HTTP semantics, and there isn't any handling about "upgrade" or even the "Connection" field in general anymore.

Yes, the line between HTTP application semantics and HTTP/1.1 transport is very thing and nobody exactly knows where things start and end. But I'm still not convinced we need web sockets over HTTP/2, e.g. in order to allow u pgrades in the application layer.
Why did it happen entirely behind closed doors? No way they got this deal together just after price caps were removed. Was this orchestrated beforehand? Domain registrations for Ethos Capital pre-date the change and timing coincides with proposed contract change to remove price caps.

What does Andrew Sullivan get for this move? Is Jon Nevett connected as well considering his ties to Donuts which is connected to Abry Partners which was managed by now Ethos Capital CEO?

So many questions, all this happening in shadows means we shouldn't give any benefit of the doubt.
Any recommendations? This looks bad really bad. Cybergoast a previous VPN bought by Kape went to shit.

For the Pia engineer who ends up reading this.

You might not need nginx if you are using Go. I would only add it if neccessary.
Seems like the laws only apply to foreign corporations, though. If you're Koch, feel free to pollute the air and rivers after funding the appropriate (re-)election campaigns.

Have you ever actually needed to look at a movie rating to know if it was suitable for a child? No, you can just use basic reason and context.
I saw this logic coming from a lot of people trying to push these changes through. They've been good so far, we should just trust them. They stick their heads in the sand and pretend we don't need rules because organizations, people, societies follow norms and that's enough. Until someone shits all over them, which is why we make rules in the first place. This whole nothing bad has happened yet, we shouldn't consider a bad outcome as a real possibility is ignorant and dangerous. The same people who if you look at ICANN mailing lists are still trying to play both sides, with whataboutism type arguments in an attempt to discredit people against .ORG being sold to a private equity company. I've dug into those people a bunch too, they're pretty much all connected to registry interests (https://reviewsignal.com/blog/2019/06/24/the-case-for-regula...)
That's true, but you are also probably not taping yourself each time.
Practice is absolutely the best thing to do but this little trick worked for me in my early days so I thought I'd pass it on.

Get someone you're really close to like a best friend or a spouse and have them sit in the absolute middle of the audience (or in the middle of the area where you can make out faces). When you start the talk focus directly on them and give the speech as if you were talking to that one person.

Once you get a few minutes into the speech and you've gotten over the initial hump start looking around the audience and trying to connect to other people as well. But if you start to feel nervous again go right back to your "safe" person and focus on them for another couple minutes. Then repeat the process until you can connect with the entire audience and be calm doing so.

It sounds weird but it worked for me every time.
Then again, for security he might want to use something else.
Is it only me who is amused by the irony of someone using a system with such a poor security track record to talk about ssh which is intended to provide secure connections?
This is both awesome and very terrible at the same time.

This proves that you can do magic in C but it also proves that C is really a low level assembler :-)

For me, stuff like this has been one of the prime reasons to prefer C++ over C. You can totally get the same performance and compiled code when using templates. But you gain compile-time checking and much more robust code.

(These preprocessor tricks are also popular in the BSD kernel)

All the innovation and multitude of startups can't plug the sinking ship that is the US economy. For example, how will these problems be fixed:

- US national debt at 13 Trillion.

- US debt held by foreigners at 4 Trillion.

- US total debt at 54 Trillion. Unfunded social security
and medicare liabilities.

- a costly army stationed at 150 countries around the world

- an aging baby boomer generation, which will reduce their consumer spending (70% of the US economy is consumer spend)

- U6 unemployment rate at 17%

Not to mention in this economy, the web startups face

- closed platform dominance from facebook/google/zynga/apple. if you build something they want, they will duplicate the functionality quickly

- too many other 'me-too' startups. all the seed camp startups are starting to look alike.

- lack of monetizing opportunities, as most people still don't like to pay for things online.

2015: YouTube Founders Acquire Tungle.me from RIM
Observation: For coworking and hacker spaces, apparently it reduces latency but that's about it for a business-class connection. Surprisingly, the issues of abuse tend to go away as multi-TB hard drives are self-limiting.

Potential Uses:

1. Adaptive media streaming protocols that minimize frame skipping and buffering, and instead gradually reduces quality seem obvious.

2. Outbound streaming to mobile perhaps.

Questions:

1. What is the oversubscription of the various upstream connection(s)? In other countries other than the US, this is a required bit of disclosure.

2. Which port(s) are blocked?

3. What's the bandwidth, ping and packet-loss like?
As far as I can tell, the iPhone cannot determine one's location solely from the GPS antenna. If you travel to a place where you haven't been before, location services simply won't work until you obtain internet connectivity for a few seconds.

I don't know if this is because the iPhone's GPS functionality is crippled, or if it's a software limitation. I'd imagine that if you wanted to overcome this limitation, you'd need to jailbreak your phone and use 3rd party mapping software at a minimum.

*Note: once it has located you, it will generally track you correctly while you're moving, even if you leave the area where you had internet connectivity.
I agree to that. With where battery technology right now, it's simply impractical to have a all-electric car: way too many strings are attached right now, starting from few hours required to charge (vs. few minutes for gas) and to the very first traffic jam that will drain the battery in no time. Granted, the hype will move the progress in these shortcomings forward, which is good. I'll wait until I could have a nuke car though.
Good tip. I went back and took a look at while my previously validated page was failing so badly.

It turns out this test suite is really poorly designed! For example, it can't identify implicitly associated labels, so the whole concept behind this tool is quite flawed.
Thanks for your great service; I'm seriously enjoying Pinboard. Can't imagine switching :)
I'm really happy to see this. I think sort of joshu buying the company back, this is one of the better possible outcomes for the future of the delicious community.
Full links are a available as entity references in each tweet in the api.
For me it's the assumption that if since a particular circumstance triggered an interesting social interaction, that the lack of that circumstance would mean that no interesting social interaction would occur.

At the base, it's the same hollow critique of millennials: because they do things differently (e.g. interact socially online as well as in person) they must be missing out on all the great things that the Boomers experienced.
I wonder how many Linux users permanently spoof their UA to get around pointless browser sniffing? (Then again, I guess a lot of Linux users don't frequent sites with such bad coding practices.)
You've got a typo, Poadcast is misspelled. Thought you would want to know. Looks cool for people who need such a tool.
I wouldn't. I barely understand the concept myself. :-)

...but I know it's much more involved than "a program that runs other programs".
To be fair, I think those of us who might care about the death of Prokofiev wouldn't have paid more/less attention just because Stalin also died.

Yes.

What a shame there aren't more decentralised services like email, the web and Usenet (which is now pretty much dead).

Twitter can do pretty much what it wants to who it wants, and they don't have to give a reason.

Maybe you get banned due to an algorithm mistake. Or an individual contracted by Twitter who doesn't like what you said. Or maybe they misunderstand what you said due to cultural differences.

I found my time on Twitter was fighting against a US-biased culture, and what I consider friendly banter with friends can be misconstrued as abuse by some random moderator or algorithm.
Pricing things in Sats will become more common once BTC is the dominant financial asset.
For Georgia, provided all the totals were a perfect match between initially published machine counts and hand counts, and the hand count methodology was transparent and trustworthy, this is enough to satisfy me. The only other attack vector I can think of would be smuggling in pre-filled ballots, and that's likely unfalsifiable with current election procedures (which I'd like to see improved, but until then we have to live with it).

As for why things haven't settled overall, maybe other states don't follow the same procedures as Georgia. Did all disputed states perform hand counts?
Everyone in the UK was banned - but they got round it by having an actor reading what the SF MP's said.

SF could have go round this by taking up their seats and using parliamentary privilege.

It might be, but it's also depleting a natural resource that refills _really_ slowly. Electricity at least can be (though is often not) generated from resources that do renew, like solar and wind energy.
Facebook grosses about $22/user/year from their platform.
