Looking forward to trying it out.
Wouldn't even just supporting samba, nfs alone without kernel module will make the kernel bigger than needed?

Or does OpenBSD doesn't support those network fs neither?

If smbd/nfsd build in by default, wouldn't a single kernel image with samba/nfs build-in to kernel by default trigger more attack vector/surface especially if I just want to run a simple LAMP stack?

Sorry for the OpenBSD noob questions. I am just curious on tradeoff on the decision turn off the kernel module completely.

This guy's whole article falls apart based on one terrible assumption: that Uberx behaviors are similar to taxis. There are a whole host of reasons why this is not the case. Taxis are more likely to hang out in dense, Manhattan areas contributing to short and slow rides. Riders would much prefer to take an Uberx to the airport than a taxi. Surge pricing. Etc.

for the next three months at least, Uber is indemnifying full-time drivers against slow business. Good luck competing with that, companies-that-don’t-have-a-$1.5-billion-war-chest.

This is what worries me. Uber are the freemarket dream child, but they're using their financial heft to actively distort the market. They've already driven Hailo out of the city, and I wonder who is next. I want Uber to become the de-facto choice by providing good service, not by bullying everyone else out of the city.
One thing I dearly miss from when Google Calendar first came out was the ability to type in text to create an event.

Eg - Typing "Dinner tomorrow at 7:30pm at Foobar restaurant" would automatically create an event with the correct lexical components.

It looks like they're finally reintroducing this back.
Why would people be more inclined to take an UberX to the airport than a taxi? The taxi has a flat fare. And from the map view I've seen using Uber, UberX's absolutely do hang around in dense Manhattan areas.

Glitch [1] is based on this to achieve eventual consistency through dependency tracking and replay. Its not exactly the same though: many operations commute (e.g. accumulation), but certain operations like cell assignment will never commute, so we have to dynamically disallow re-assignment. Another trick is to pair commutative operation order with transactional style rollback, which allows the repair of arbitrary executions (since you can rollback executions and redo them in any order!).

This is the worst kind of comment and what is wrong with Hacker News.

This article is poor scientific journalism. "New clock may end time as we know it." Seriously? How is that remotely true? There is nothing in this article that justifies that headline. If anything, this new clock affirms our understanding of the nature of time, pointing out the minute changes that we expect to see but have not had instruments sensitive enough to measure until now.

But that desire to pin down the elusive ticking of the clock may soon be the undoing of time as we know it: The next generation of clocks will not tell time in a way that most people understand.

Undoing of time as we know it? Will the existence of this clock somehow magically make all other clocks in the world turn incomprehensible? No, the truth is that most of society won't even be aware of this "undoing of time as we know it."

And on the subject of telling time in a way most people don't understand, that is already true of the cesium clocks they mention. We already have to deal with relativistic drift, of which most people are ignorant.

But this new clock has run into a big problem: This thing we call time doesn't tick at the same rate everywhere in the universe. Or even on our planet.

This line makes it out like we didn't know about relativity. Also, I hardly think more precision is a problem. If anything it gives us power to do things we never have done before. Technologies like GPS wouldn't work without the current generation of clocks. I'm excited about the new possibilities that an even more precise clock will open. It's not a problem.

They just may not be able to tell us the time.

What?!! This is incredibly misleading. The new clock will be just as able to tell time as all of the clocks we've had up until this point.

I could go on, but nullc is right, this article is crap. It is dripping with sensationalism.

Fitting to a statistical model superficially makes sense. But I think the details kill it.

The outcome you are measuring is the change in test score from before having a teacher and after. VAM attempts to statistically estimate the teacher's contribution to that change.

Presumably, the test is of something that theoretically the students will not know beforehand. Which means the teachers don't want students who study on their own (or participate in activities where that knowledge might be useful). And they don't want students who aren't going to learn it -- whoops, that was a leap, I meant to say who aren't going to test higher at the end. So you don't really want the top tier nor bottom tier coming into your class.

Nonspecific to VAM, but a result of standardized test results being used for anything meaningful to the teacher (salary, tenure, etc.) is that anything not on the test has an opportunity cost, and so will be omitted in favor of test prep. The more statistical validity that VAM has, the stronger this effect will be. If the teacher shows the students how to incorporate their new knowledge into a broader perspective, it may make the school's scores improve but it will screw over the next teacher in line (because the before test will be higher). So there's some peer pressure to make sure the students learn nothing that they're "supposed" to learn later.

If you consider a subject like math, what happens is that at some point many students fall behind. This makes the later topics much, much harder, because they build on what they never quite understood. A perfect teacher would figure out what balance of old and new material to give each individual student. That perfect teacher would score poorly on VAM compared to a teacher who crammed in test-specific mechanics and regurgitation, relying on dismal beginning test scores to make poor but not awful ending test scores look good. The system would gradually optimize for squeezing incremental gains out of improperly taught students.

And don't forget that the outcome is what's measured, and what's measured is crap. In football, you can look at a score (or just who won). Here, the structure is tuned to produce students who can do well on year-end tests but nothing else, certainly not on their ability to apply their knowledge to situations not likely to show up on a test.

Ok, this became more of a rant against standardized testing, but it just bothers me that adding statistical power magnifies the problems. You'd be better off throwing in a large random component, so that teachers' innate desires to teach well have a chance at winning out over gaming the system. Because even if your population of teachers is really conscientious, you're actively selecting for those most willing to play the game. And selection always wins in the end.
I'm guessing that the housing market is dancing with the maximum value of "1/3 of the typical house-buying population's salary" that buyers are willing to pay. If a lot of house-buyer are couples and they make $75-100K each, then that is balanced against maximum-tolerable commute time and voila, prices drop off once you get to Hercules, Tracy or Gilroy.

You didn't really respond to his No one cares about your intellectual superiority, or the fact this might be a special interest for you part of his comment.

Your tone and delivery is a bit offputting.

And the thing that I didn't see you comment on that I found particularly fascinating was that the increased resolution of these clocks is such that you can discern differences in relativistic effect between floor and wall. That changes how I think of time.

(My favorite headline that I read sometime around 1965 is "Dating Events in the Vicinity of a Leap Second.)
> Time itself is flowing more quickly on the wall than on the floor

Velocity is a function of distance and time. How can time have a velocity? Couldn't you also say the distances in the clock stretched or shrunk by the lorentz factor?
It sounds like Boot has had a lot of thought put into it, and I certainly welcome the idea of effectively immutable directories.

But it also looks like Boot dives head first into I/O, when I'd prefer a build tool that is a little more circumspect about complexity. While I welcome competition to Leiningen, and I'll certainly keep an eye on Boot, my initial impression is that it's heading in the opposite direction to where I'd want a build tool to go.

That's a nice example of some elegant and readable code.
To be more specific, when I said that C4 "emulates" the Vega architecture, I was referring the way that you presumably need to be able to invalidate an operation when another thread concurrently reads or writes to shared memory in the middle of a transaction (i.e. copying a black and updating pointers). By emulate, I meant you need to construct a primitive that provides an efficient lock-free large block copying operation, similar to what the Vega cache system provides. Of course, that's only a primitive--you need to then build compound operations atop that, and there's more than enough engineering there to keep people busy for quite awhile.

Again, if you can claim that in fact your page mapping and protection schemes are not analogous to the transactional memory support in the Vega hardware (which looks to be both small block transactional memory tied into the cache controller, as well as some useful page-level operations built into the memory controller), then mea culpa.
It's not just about how much weight the stand can hold. How well-balanced is it? How well-balanced is it while being raised or lowered by hand? Keyboards are typically fairly even in terms of weight distribution, and have a low center of gravity. Monitors, not so much.

You seem to assume that money is the sole motivator, everywhere.

What's really going on is that you're trapped in your own world view, validated by people like you, all alike in your social circles.

My advice: at least try and get out of it a little. I'm up to my gills in the high-tech culture, working at a startup in the Silicon Valley - but my wife is a teacher. I went to a Halloween party hosted by some of her co-workers - it's a tremendous difference in terms of culture, ideals, etc. It was literally like meeting people from a different country.

Metrics aren't the final answer to every question. When dealing with people (which is what education is doing), a simple, single, narrow number used to reduce everything to a handy metric can be incredibly misleading.

Whenever I head some folks saying that we need more metrics and more competition to make the education system better, I just want to tell them: "thank you, but sit down and shut up, cause you've no idea what you're talking about."
> that teacher does not exist

The proposed model makes no assumptions about the "average" teacher -- it proposes a simple metric applied to student performance. Under this metric, some teachers would get a positive score because their students' scores improved more than the average. Others would get a negative score because their students' scores improved less than the average.

> would this model prevent it?

I don't know, but the goal of the model is to prevent this, or even reverse it -- that is, the best teachers would want to work with the least advantaged kids, because arbitrage -- it should be easier to make a difference for kids starting at a low performance level, and harder to make a similar difference with kids starting at a higher level.

I don't know whether this works even a little bit in practice, but the thinking sounds promising.

Interesting and relevant comment from cbrozefsky, which is marked dead.

ThreatGRID, now part of Cisco, uses clojure in our malware analysis and threat intelligence platform. It's a core part of our analysis engine, which examines all the things malware does and how to detect it on the rest of your systems. We've built a 1980s "expert system" startup using core.logic.

It's also the core of our API service, and the UI built on top of that. We use clojurescript extensively in the UI, and have been moving large parts of it to Om.

It is a key technology for us, letting us build better analysis tools, faster and more performant than other languages. We have clojure code in production both in our SaaS offering, and shipped to many large finance, government, and corporate customers around the world.
With cable, at least it's possible to never subscribe in the first place. That doesn't work with governments.
I feel like teachers don't ever want to be evaluaged on their performance, yet want raises every year. Without a system in place to get rid of bad teachers and reward good ones, education will stay broken in this country.

Nearly all professions are evaluated and you can be fired. Why should teaching be any different?

Unions are one of the main reasons things haven't gotten any better. As soon as you try to evaluate, the unions step in and stop it.

There is a claim that some positions of power make people unqualified to make choices.

I'm not commenting on morality here, but the state of current law.
Well, this is one teacher in the state of New York. Even a very stable measurement might give a few funny results every now and then.

(Of course, she's probably not the only teacher in New York with a similar story. But I don't know that there are very many.)
And it's hard to do that even when the desired outcome is just good code.

Now try and do it when the desired outcome is good people (education).
Yes, and then you can figure out different values of a and b for a different teacher, different class, different year, different town, etc.

And you're really left with c*teacher_skill + noise, where the noise in the teacher_skill measure may be what results in some good teachers getting bad ratings.

In my view, empirical modeling assumes that there is some underlying regularity that can be modeled, but this assumption seems questionable. And part of the process has to be to decide an acceptable level of good teachers getting bad ratings.

The idea of a multiverse is a derivative idea from Western religion/philosophy. It's a modern variation of the principle of plenitude. "The principle of plenitude asserts that the universe contains all possible forms of existence."[1] It's not a peripheral idea either but a cornerstone of pre-modern western ontologies.

My wife is also a teacher(1). While I didn't go to a Halloween party with her coworkers this year I've been to quite a few other parties with teachers. So maybe don't make assumptions about my world view huh?

I never said that metrics were the final answer to every question either. Teaching is obviously an incredibly nuanced profession. If, as Michael Lewis showed us, we can't even measure baseball player's performance very well then oh gosh it's going to be much much harder for teachers (or programmers too!).

But that doesn't mean there aren't any differences in skill either. There are great programmers. There are not so good programmers. There are great teachers. There are bad teachers. If we deny this reality and just pay them the same amount then eventually the good ones are going to figure out they're getting screwed no matter how much they intrinsically like the gig.

In the outer boroughs there frequently ARE no taxis. So you have a bunch of Uber rides that used to be car service rides which distort the numbers.

How is it a 'fallacy'? To be clear, this has nothing to do with the actual streaming (which does not happen from EC2) but instead are the basics like viewing history and categories. It absolutely is the simple part of the application, albeit, as mentioned, at a very large scale. Given that someone else mentioned it, does Netflix even bother with the whole recommendation algorithm thing anymore? My personal experience has been that it gives the most superficial of recommendations.

And if we're being honest, the Netflix app layer is kind of terrible. I could enumerate the problems, discoverability being king, but it is not the compelling part of the service.
> Your performance is measured in a single week at the end of each year by statistically-controlled standardized tasks.

My main point was that if you're going to appraise teachers based on their students' standardized test scores, it would seem to make sense to use a statistical model that tries to measure how much of an effect the teacher has on the predicted test scores of their students. I'm completely open to the argument that we shouldn't be appraising teachers based on student test scores, but that does not seem to be the position the article is advocating.
This makes great sense! I'd guess this would be (relatively) easily integrated with a standard hybrid system, although the powertrain would be quite expensive (hybrid system PLUS turbocharger system).

I wonder if this would work well with a turbodiesel engine?

Also, I'm a bit confused: why is this not an electric supercharger? I thought the 'turbo' name meant that there was a turbine that spins using the engine exhaust gasses, which drives a compressor that compresses the intake air. This appears to spin using an electric motor instead...
For the first time in my life, I cried when a celebrity died. RIP Tom.
Your assuming the delta is based around just the prior test scores vs this one. aka old 10 new 15 or old 80 vs new 85 is the same improvement. However, statistically there is a tendency to regress toward the mean making simply staying at 80 end up as statistical progress. However, I suspect their using a flawed model that ignores the tendency for school districts to pack high preforming teachers on top of other high preforming teachers. To correct for this you need to look at what happens when someone moves from one district to another.

PS: There is a fair amount of momentum in many subjects so teachers can impact not just this years test results, but next years as well. In the end it's really difficult to come up with a high quality model and my guess is they simply did not bother.

Just wanted to say thanks for this post. I read it this morning, and after lunch had the worst allergic reaction I have ever had. Luckily I already had epipens, just in case.

Anyway, thanks for the PSA.
