Obligatory reference to "Children of the Magenta Line"

http://independentflightinstructors.com/instructors/2011/11/...

(Automation systems typically tell the pilot where to go with a magenta line, on the G1000 systems I am used to it's an indicator of GPS navigation)

From the opening line: "as we look at this accident history, we find that in 68% of these accidents, Automation Dependency played a significant part".

So automation certainly is not the solution currently, at least not by itself. It handles a lot of the routine very well, but not non-routine situations, which happen frequently enough. Big events like Captain Sullenberger's Hudson landing have been mentioned, but there are many other smaller situations that occur on a regular basis.

On the other hand, automation has been a crucial part of making commercial aviation so incredibly safe and accidents so rare that we no longer really have a statistically relevant sample base. That's an enormous achievement, but automation is only part of the story.

The current amazing safety record has been achieved with the current consensus/compromise setup: humans + machines.

Most of the problems that happen nowadays seem to happen due to problems at the man+machine interface. Asiana 214 for example would have been fine as a fully automated approach just as much as a fully hand-flown approach, but confusions between the automation and the pilots caused a crash.

However, looking at those statistics and saying "we must remove one element" is fallacious, simply because the statistics do not show how many crashes were prevented by having that element aboard.

So while these sorts of radical proposals sound good and appear to make a lot of sense when not examined too closely, I would be very surprised if the objectively best solution is not the combination that we have, refined further to smooth out problems at the computer/human interface.

Automated trains and cars have been mentioned as examples. Planes are fundamentally different, because with any surface bound vehicle you can, in an emergency, just stop and wait for help. For a train, that's literally it. For a car, you'd probably want to pull over somewhere safe, but if worse comes to worse you can stop in place and hope everyone around you stops as well or avoids you.

If you "stop" a plane in flight, everyone on board dies. You have to actively land the plane on a suitable surface at suitable speed and orientation, arguably the hardest part of flying. That's also one reason why requirements for airplane engines are so different than for cars: if a car engine dies, you pull over. If a plane engine dies, you also die unless you find a good place to land in the next couple of seconds or minutes.
Also, it seems possible that large scale DOS could be performed by applying for domains (via DNS hijack) before the owners do, causing significant administrative burden to recover from. I would suggest allowing simpler revocations within some multiple of the DNS TTL value for the domain.

I can also envision unscrupulous registrars pre-applying for LE certs for a fee, like $5.99 per month, and being very tardy and uncooperative about relinquishing control.
I've always liked to imagine a future where games are actually telepresence modules allowing users to mine asteroids using robots, monitor servers in a global cluster and protect them from attack, or run undersea farms here on earth, all from their home and with a sense that they're collaborating on a fun activity with friends.

So instead of skinner boxes trying to get people addicted to pointless tasks and extract money from them for worthless virtual attributes, they'd actually be useful ways to earn a living. Probably instead corporations will find ways to make gamers work for them and earn them more money.
Do you know if they work with typed arrays?
You wouldn't be in a very good position to revoke them then, would you? For example, if we had another heartbleed.
Hrm I think I love the tagline more than the site. I really like what OkCupid has done and would love it if someone actually built a jobs site that worked in the same way. Both sides have lists of questions which are presented to them and they answer them and/or rate how important the answers of their prospective parter are. How would this work for a job site?

Q. What's your favorite CSS preprocessor?

- sass
- less
- I don't write CSS

Q. Do you want to work in an office where there are dogs?

- absolutely!
- that would be cool
- don't really care

etc.

I think there are a LOT better ways to find good employee/employer matches than pulling in job listings and resumes. OK Cupid for jobs is a great idea, I just hope you end up building it!

getrandom() is a generic interface you can use to implement getentropy(), which is used to seed arc4random(). It is not an alternative arc4random implementation...

From the OpenBSD Manpage:

getentropy() will succeed unless:

[EFAULT]
The buf parameter points to an invalid address.

[EIO]
Too many bytes requested, or some other fatal error occurred.

See: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/...

There have been many incidents where it took both pilots to save the airplane.
Summary of what you can do for yourself:

1. In Linux, use the fq_codel queueing discipline for your interface which sits on your fast-to-slow network boundary:

tc qdisc add dev $IFACE root fq_codel

I'm definitely talking about Sedgwick. I'm not a huge fan of Tim Roughgarden's presentations, honestly. My mistake about the university.
>> If no state gave an incentive, they'd have to pick one at full price anyway

Or build it in another country and people could scream at them for being unpatriotic.

>> Also, if the deal is good with Tesla, why not give similar deals to every company that wants to put up a building?

You are arguing for lower taxes. This is a noble goal, but much harder to achieve than such deal. As Bismarck said, politics is the art of the possible. It's not ideal, but given current situation it's also not the worst outcome.

>> In the end states will just forego corporate taxes altogether and get all their revenue from the people.

Corporate taxes are about 10% of budget income, despite US corporate tax rates being one of the highest in the world. So it's neither unprecedented not unimaginable to have lower corporate tax rates. As for the people, corporations are ultimately owned by people, so it's still tax on people, just certain kind of people - doing business in the US. Every dollar taken as corporate tax is not paid as dividend, not invested in hiring another worker, not spent on buying supplies or services. So ultimately it's people all the way down.
I do t know about the "some", but that is what that Apple engineer says:

Which leads to the problem of centering. I wish to center a bitmap image within a button's border. The image is 101 logical points high, and the border is 200 logical points high. With a 2x scale factor, I can center absolutely, and still be aligned to device pixels. With a 1x, 1.25, 1.33, etc. scale factor, centering will align me on a partial pixel, which looks like crap. So I have to round. Which way? If the goal is "make it look good," then the answer is "whichever way looks good," which depends on the visual style of the bezel, i.e. whether the top or bottom has more visual weight. So now we need hinting.

And that's where things start to get really nasty. In order to make things look good at arbitrary resolutions, we want to round to device pixels. But the rounding direction is not a local question! Consider what happens if we have two visual elements abutting in logical coordinates, and they round in opposite directions: now there's a device pixel between them. That's very visible: you get a pixel crack! So you have to coordinate rounding.

Question: even with hinting, is it actually possible to make a font where two glyphs align perfectly without white space between them?

WPF is a good example of a framework that attempted resolution independence and encountered this problem. Initially it has the "SnapsToDevicePixels" property, which triggers rounding behavior at draw time. But draw time is too late, because of the "abutting elements rounding in opposite directions" problem. So they introduced the "UseLayoutRounding" property, which does...something. And the guidance is basically "turn it on and see if it helps, if not, disable it." Great.

I think a way out of this is way higher DPI with some blurring as the last step. That's what print does. At 1000 or 2500 DPI nobody will notice aliasing anymore, and he blurring would take care of small cracks between objects that supposedly are abutting, make cases where two objects that shouldn't accidentally do overlap less obnoxious, etc.
As others have noted, this is capital cost per kWh of capacity.

Compare against Beacon Energy's 25kWh flywheel storage units, which have a cost of $10,000 per kWh.

There are trade-offs. Beacon's system is very highly responsive (flywheels can pretty much take up or deliver as much energy as you want, with response in the second to sub-second level) directly receive and deliver electrical energy, and have extremely high round-trip efficiency (90%+, approaching 99%). As an alternative to spinning reserve they have benefits.

http://www.beaconpower.in/html/technology.html
http://beaconpower.com/

The problems are the limited capacities of individual units (25 kWh isn't that much power at grid scale), engineering problems, notably precession (the Earth's own rotation about its axis is a concern for the units), and interesting failure modes (preferred deployment is burying the units in below-grade concrete containment with massive lids -- you neither want systems flying apart nor wandering about the neighborhood at 16,000 RPM should the come unmoored).

Flywheels are among the more expensive energy storage options available, but at least at first glance the cooling option looks reasonable.
Even ex-DDR still did not catch up with the rest of Germany - and one generation did pass.
And they were just 3x poorer, where DPRK is more like 15x poorer than ROK.

I doubt that SE countries you listed lost 100k+ people due to hunger (in 90-s and 00-s anyway). Sure they are poor, but they can handle it better than command economy. They're used to be poor, not shocked by it.

Not sure if I'm getting downvoted because I was a looter/griefer or because of my blunt question. If the former I want to point out that looting/griefing was a big part of the game and not a destructive element. Stealing from other players was a skill where you advanced just like in swordsmanship or magic. It would flag you as a criminal but still a valid profession. Good looters and griefers gained world-wide recognition and stardom. Just check out the Galad the Looter and Belan the Looter comics.
> If you're a pro performing well enough to be invited for an entire season, you technically only have to play four one-week events per year. Being physical and physically social is a factor.

Yeah, but only technically - in practice, intense preparation before each pro tour greatly increases your chances, so that's what most pros end up doing (esp. since the introduction of magic online, where they can practice, test out ideas etc. 24/7).
All of your posts pretty much talk about how you think "information wants to be free" (aka: free music, movies, games and other entertainment) so I don't see any strawman here.
I did a start-up in Algeria few years ago. Didn't work great but was a very good experience. Big issue is red tape, too much of it as long as we'd have the same bureaucracy I think things would move slowly.

Just to follow along cdr's comment, I want to point out that you never hear about anyone who sent their life down the drain over Magic. And it's because, as noted, if you sink money into the game, you can recoup some percentage of those costs by selling your assets.

Say what you will about CCGs: they do, at least, provide you with tangible property that is unquestionably yours. That is not something WoW can claim.
Does it also extract methods, convert fields into accessors, move code between packages while updating import statements, update comments that relate to code, move methods across types?

Yes in that it's utilizing compressed gas for energy storage, but no in that in how they're addressing the issue of adibiatic heating and cooling of gas -- the fact that gasses heat when compressed and cool when expanded -- they're actually using this heat itself as the energy storage mechanism, with argon as the working fluid.

Light Sail's approach harvests the provided heat and cooling, but utilizes those for what is effectively a coordinated heating/cooling service. The heat itself isn't part of the energy storage/recovery process.

Both are interesting approaches to the heating/cooling problem.

If you don't allow for the heating and cooling, you run the risk of explosions or of excessive thermal loss from your compressed gas. Explosions are possible if you're storing large volumes of gas in underground former natural gas reservoirs -- injecting large volumes of high-temperature N2 + O2 atmospheric gas risks igniting the residual methane. You also have the problem of icing over your recovery apparatus. As a consequence many CAES (compressed air energy storage) designs incorporate a natural gas burner on the exhaust side which both heats the expanding gas and adds additional energy to the process. The resulting systems are a hybrid of natural gas generation plus energy storage.

Twisted, Nodejs and all of these other frameworks use the select system call under the hood. This works well when the process is IO bound. Processes that are responding the HTTP requests or reading or writing to databases tend to be IO bound.

The select system call takes a set of file descriptors and returns which file descriptors you can read, because new data is available to read. These frameworks read from these file descriptors and dispatch the new data to a callback method. The event loop only processes one thing at a time, because it is single threaded. However, since reading from the file descriptor and processing the callback is usually fast, this scales very well. Once again, it only scales well for IO bound operations. This uses less memory than having a single thread for each HTTP request, and it definitely uses less memory than having a single process for each HTTP request.
Sorry, I use a throw away account for this post. This is a weekend project of me and my buddy, actually more of my buddy to be honest. We hammered it together last year over a weekend after lots of drinking. It is based on Django. We had 20k visits a month but this had declined due to a spam problem. We had to delete all the comments and use a captcha to prevent this in the future. We want to spent a little time now in this project to see if we can gain traction.

So, Any comments?
Face is not a singular object. Its a collection of colour, hair, nose, ears and so on. Wont the tenet of evolution is that each generation there will be some random change to these aspects, which makes the face unique across the humans ?
There's still a huge dearth of rigor in defining both the width of a range of environments, the degree of success in achieving goals, and the significance of various goals. I'll expound briefly on the first. Who is to say that the range of "environments" a chess supercomputer faces is narrower than the environments a human faces? Obviously, we intuit our range of environments to be wider, but can we explain why rigorously?
It's even worse because you might code up a storm and not add any value. You might work a dead project and only loose the company money. I have seen many a John Henry try to save a project from technical failure when it was a business failure.

I feel you're mistaken on all three counts here.

1) She was productive. She just wasn't productive at being a college student.

2) She doesn't sound like she was being entertained. She sounded like she was handling logistics and leadership roles with great competence. To me, what I hear is "job satisfaction", except without pay. That's not entertainment.

3) Needing to entertain yourself is an excuse for not graduating. Probably not a sufficient one, but it's a valid one. Honestly, I think it's more accurate to say she dropped out due to burnout from working effectively two jobs.
One element of using intermittent or variable renewable energy is to take the approach of dispatching demand to meet your available capacity rather than dispatching capacity to meet demand.

Presently, electrical generation relies on base-load power -- plants which run very nearly all the time, typically coal or nuclear -- with "peaking" and matching capabilities -- generation which can be rapidly added or removed, with response times typically measured in minutes (grids can change fairly rapidly, but not that rapidly, and much demand is highly predictable based on weather, human behavior, and other patterns).

Some large power loads can effectively be banked, and heating and cooling loads are key among these. By providing a large thermal storage mass (either hot or cold), it's possible to "bank" energy when there's a surplus, or when generation is low-cost, and draw down that bank when energy's scarce. Other alternatives are running energy-intensive processes which can be cycled either rapidly or predictably as needed. Aluminium smelting (very electrically intensive), hydrogen electrolysis, and other industrial processes are candidates for this. It's also effectively how pumped-storage hydro works.

You may not be getting back electricity directly, but by offsetting a large cooling load, you're shifting demand.

I suppose if the second scenario is correct and the bureaucracy lasts 10,000 years into the future there's not really any harm in having developed the signage anyway. But on the other hand, if we just assume that the knowledge will be passed on via bureaucracy or some other means and don't develop the signage and then those methods of transmitting the knowledge fails, it could be bad for people in the future.
