So you select one country, over a carefully selected period of time, you select one parameter amongst hundreds to explain one other. I'm not very good at US history, but slavery, an almost infinite amount of natural resources comes to mind, more that the tax system. While during this time European countries were still wasting resources in wars, throne successions and a mostly feudal system.

If I give you another country that pushed people out of poverty into middle class with heavy taxes (Germany after the war for example), then I win at telling the taxes are not the primordial criterion?

Or maybe we cut the crap and we look at global data, statistics and economic theory instead of looking at one datapoint and make it an example.

Millionnaires are a very small population, they are statistically irrelevant at the people level. Having a very few millionnaires, all of them self made, doesn't influence the social mobility. Otherwise, a few winners at the lottery in a very poor country (imagine the winners being more numerous than the war profiteers) would be enough to claim that it's a country where there is social mobility. You're just looking at the statistics of an infinitely small population.

edit: and I probably forgot to throw some Chinese railroad workers in there.

My feeling, from limited experience, is that it is easier to bring/hire people into an existing/new process than it is to change an existing process people are familiar with.
If anything this shows there is a ton of low-lying fruit for the Feds to pick to improve operational efficiency. This along with the Pentagon's inability to do accounting should allow for big improvements. And due to budget constraints and more government services coming online (Healthcare) there might actual be a reason to push through some of these changes. Or at least that is my hope.
Then we should have higher social mobility in the US than in France right? But it doesn't seem to be the case (look for "Country comparison"):

Note also that the northern Europe countries are much better than either France or the US. Not really low taxation countries either.

This article is pretty thin. We are currently building out a clustered application on corosync/pacemaker with postgres synchronous replication and tomcat, and I have mixed feelings about Linux HA so far. It isn't too bad to get something basic set up (cluster with virtual IP for instance), but when things don't work it can be difficult to figure out why. If you are looking for a distributed filesytem GFS2 in this stack isn't bad. However, it seems like there are a lot of differences between package versions, and the interactions between versions of heartbeat, corosync, pacemaker, crm, pcs, your resource definition ocf files, the stonith resources, cluster-glue, along with the linux packages makes problems hard to track down and much of the web info you do find out of date. I've often had to resort to irc or the mailing list to try and figure things out, and even then sometimes it seems like nobody knows. The whole thing feels a little bit shaky at first, but it is possible to build a solid cluster on top of it with enough effort.
I meant more about patient education in general rather than specifically discharge instructions.

also, from my experience, the stories of patients not understanding something about their discharge and then being readmitted because of that lack of understanding is far less than the cases of patients being readmitted simply because they chose not to follow specific instructions regarding their health.

You can't fix fat with education (no matter how shiny of a device it's on) and fat, generally speaking, is what causes a lot of of the chronic diseases that perpetuate the need for hospitals in the first place.
The author left out one major reason textbooks are so expensive-- course adoption lists (i.e. which books go with which courses) are kept private or disorganized so that students or businesses can't offer rival "Search by Course" type sites without scraping the local bookstore. As a result students go to the bookstore which knows their requirements unlike Amazon.com.

I open sourced a course data scraper a while ago to help solve this problem: https://github.com/bsgreenb/Open-Textbooks

In contrast with his previous posts, this one does not seem to contain much in the way of novelty, as nearly everything is already contained in the ed25519 paper [1]. To summarize, ECDSA is bad because (in order of gravity):

- It requires cryptographic randomness for each individual signature;

- As a NIST standard, it is defined over the NIST elliptic curves, which are not particularly implementation-friendly;

- The standards give little to no guidance on implementation issues;

- It is slower than necessary, requiring inversions during signing.

DSA was a step backwards from the Schnorr scheme, which was the superior option at the time. The blog post (but not the ed25519 paper) seems to forget that Schnorr was never practically adopted due to patent issues, similarly to IDEA, OCB, and many other schemes left on the patented algorithm wasteland. Legend goes that the DSA was designed with the express purpose of avoiding Schnorr's patent, while still resulting in a similar scheme. Since the patent expired in 2008, this is no longer a concern, and certainly not for a signature scheme designed in 2011.

The main point is the sheer mass of regulations and laws affecting and quite possibly contradicting each other.

Essentially you try to make a system that "fits all cases"... with every possible permutation. Bound to fail, actually.
Same here, check my above comment.
Who said anything about incentivizing?

We have to ask ourselves why college is so expensive.

When some people read articles like this, they call for more government aid to students. "We need to help young, hard working students from unprivileged backgrounds to pay for college!" Their hearts are certainly in the right place, and it isn't an unreasonable idea at first glance.

However, could this idea be part of the problem? Maybe giving people free money for college isn't the best idea.

There are four ways to spend money:

1) You spend your own money on yourself

2) You spend someone else's money on yourself

3) You spend your money on someone else

4) You spend someone else's money on someone else

When you spend your own money on yourself, you are very selective with how that money is spent. Not only do you gain from what you buy, you also lose money you could use to buy other things. The other three situations are ones in which being selective isn't as important to the spender.

Why does this matter? When people pay for college themselves, we are in situation 1; they have an incentive to choose a college they can afford while still being a great place to learn. When a student gets free money proportional to tuition, they can choose a school that charges ridiculously high rates for tuition. (Student loans are a middle ground. They are still spending money on themselves, but people the age of college students tend to be more frivolous with loans than money they earned, so they are still less interested in the price.)

The more students that get free money for college, the higher the cost of college becomes, because the equilibrium price of college gets distorted. If all student aid disappeared tomorrow, then certainly the cost of college would decrease.

If colleges get more money, then where does it go? Certainly not directly to education. It goes to fancy buildings to impress donors, and supporting the ultimate cash cow: government research grants. It goes to inflating the administrative staffs and inflating the salaries of the highest ranked members of that staff. If it was possible to pay for college on minimum wage, I wonder why we ever changed the system.

Anybody ever heard for such a kind of gateway?
R and S are the two signature elements. A is the public key, B is the common base. That is, A = B^a in prime fields, or A = a * B on elliptic curves. R is a random element used for each signature, usually R = k * B for randomly generated k.

Note that those equations are only covering the verification part of the scheme.

In India, at least at IITs, we get assignments and course material on email or as hardcopy kept at campus photocopy centre from where students can get copies at cheap rates. We hardly bought textbooks. The once we bought were very cheap. I think the most expensive one I bought was for $8 at current rates. Don't you guys have libraries ? Whenever I needed to consult a textbook I used to go to the library and read it there.

Moreover we get "Indian" edition of those books which are written by Americans and those used to be as cheap as Indian author text books.

"It'd be a strange thing to pitch to investors too."

I think there is something here actually.

For example it's a constant annoyance to me that when I get chinese food or sushi from the same places on a regular basis I actually have to make a phone call and talk to someone. At one place where they know me they actually make me give them my phone number which allows them to pull me up in their system. Just having to recite my phone number annoys me to no end.

I am sure there are obviously people who have solved the problem of using a smartphone or a simple web interface to help order pickup food (or delivery). But they haven't made any headway in the major city suburb where I am located.

For the life of me I don't understand why someone doesn't create a "bingo card creator" [1] type business to serve this market at a reasonable monthly fee. Most ideas on HN are "start by getting funded or incubated" as opposed to things that actually could be sold, proven, and then scaled. Write the app then knock on some doors and sell it (after giving it away to test restaurants for free).

Linux High Availability is certainly still used a lot within application infrastructures, especially in some of the smaller ones. However what I find more interesting are the architectures that are performing all of the availability functions in the software layer such as in the application or database code, as typically these are simpler and offer far better scalability.

I have been working remotely for the last year after working in an office for ~14 years.

The largest potential issue that I have run into is is communication and how it is handled.

The most important thing I would ask would be how many of the people on the team you deal directly with are remote. That will give a pretty good gauge on what it will be like.

I would also ask why they chose to open up remote positions. Is it a last resort to get people hired or is it because they just care about the quality of the hires. You may or may not get an honest answer here, but I would ask it any way.

The other I would ask is what is the primary means of communication in the company. If they say "Campfire", "Flowdock" or something along those lines - ask how many rooms they have and how active they are. The key here is asynchronous communication, with remote positions come different schedules, removing the need for instantaneous response is nice.

Along those lines I would ask about hours that people work, are there core hours or is it 8-5 Pacific time, etc. If there is a rigid schedule, that is a bit of a red flag for me.

I would also ask how often the team gets together, this should be a priority and I think once a quarter minimum would be a good time frame.

You mentioned a devops role, so this might not be as big of a thing for you, but I like to see them using pull requests (or similar methodology) for feature merging. In my experience thus far, those have really helped keeping team members up to speed. That isn't a deal breaker, but a good thing if I see it.

Many of us over here in Europe lost a lot of respect for the NYT when it failed to denounce the complete garbageness of the Saddam-WMD connection, which was widely reported on over here.

Personally, I was also disappointed when Cablegate happened. I still own all five newspapers that collaborated in the dissemination and back in the day I read through the reporting of every single one of them.

Only one did not apologize for reporing on the cables (El País). The NYT, on the other hand, was the most apologetic by far.

A free press should report on all the secret shenanigans. Clearly, in the past, most major newspapers in most countries were not free in that sense, as they have refrained from reporting certain things on the intelligence agencies of their home countries.

This includes the Western World. In my home country, Germany, we recently were made aware of the fact that the West German intelligence agencies had opened and read all correspondence between citizens of East and West. Best detail: If they couldn't re-seal the letter in such a manner that you wouldn't know it had been read, they would just throw it away!

Somehow, this was kept a secret for decades, even though a massive amount of people were involved. So much for free press.

I guess the Americans have to decide. Do you want to be West Germany? Or do you want to be the United States of fucking America?
That was actually my first thought as well, but came to an opposite conclusion: it's even harder now for students because there are no jobs above MW.

Today there are MW jobs, and there are middle-class 40/year jobs, but there not much in between. I'm 30 so I don't know for certain about the past, but the only higher than MW job I could find when in school 4 years ago was delivering pizza.
So you achieved your goal right? Historically bakeries are very 'spikey' in their demand, a friend of mine runs one and they spend 3AM to 6AM making donuts and bagels which they sell out of between 6AM and 7:15AM, and then sell maybe a handful or two for the rest of the day.

Given the complexities of bread, it would interesting to hear a post mortem about ways you might both account for spikes without compromising delivery times, delivery scheduling to make maximum use of delivery resources, and even recipe variations to support those goals.

I disagree based on my experience with equally bureaucratic and wasteful private organizations. My take is that we simply don't have the right organizational frameworks to undertake large, ongoing tasks involving lots of people.

I don't know what the answer is, but watching the results of privatization binges in a number of countries in the past, I don't think it involves moving things along the public/private axis. There are more ways to motivate people than just competition.

I suppose you're located in the south of Italy, as in the north (Milan for example) bread (standard, not multicereal or special ones) is around 4-5€ per kilo.
NB I'm Italian now in Luxembourg and one of the thing I miss is the quality of bread (here it is generally not very good, too many "boulangerie" of the same brand, Fischer, with all the same bread / taste). And of course it is even more expensive...

> It goes to inflating the administrative staffs and inflating the salaries of the highest ranked members of that staff.

This. Bureaucratic bloat, no accountability and terrible efficiency. Many Universities are the largest employers in their state.

Do our Universities exist to be Research and Educational institutions, or to employ armies of admin workers that push papers?
> You can use a write-once hardware register at the end of the boot sequence for similar effect.

Or use a turn-key switch. First put it into II, wait for the boot sequence to complete, switch back to I. Yes, that does require someone to be on site but that tends to happen anyway when someone restarts the ATM in the first place. If you want to update the software remotely, you could download it into ramdisk and run it from there. For the base system, you'll want something robust so it's more or less guaranteed to get to the point where you can manage it remotely. And you could verify the downloaded application bits against a locally installed root certificate.

The old MS-Windows-based ATMs may be rebooted daily, but let's face it, that's just because Windows. When the base system has to be updated for some reason, a service technician will have to physically replace the storage device for it. If that happens very often, they're either doing it wrong or I'd recommend against such a setup. But perhaps the vendor can charge for the service, in which case /care ;)

Or they could turn the key into II every last Monday of the month for example (the ATM would go into maintenance mode) at a certain time and let the big maintenance server do its work overnight, avoiding the situation altogether at the cost of a slightly greater risk that the machine becomes defective.

In any case, a tiny embedded OS would be perfect for the job.
Nope, it was a MVP.

I teach at a community college, and as it was explained to me by our financial aid office, student aid isn't paid out until a few weeks in as a mechanism to prevent financial aid fraud. Every year people sign up for classes, collecting their financial aid money, and then never show up. Community colleges are the primary target for this type of fraud, since we have open admissions.

The federal government is not okay with this, so they instituted a system of mandatory reporting where we have to keep track of whether or not a student shows up during the first few weeks. That way they know who not to send aid to when that time is up. If we fail to properly report this then the college is expected to send money to the federal government to make up the difference.

So it's not a trick on our part to get you to use the campus bookstore. I personally encourage my students not to use the bookstore, since I think marking up the prices on textbooks is inappropriate. I've also pushed hard for the adoption of open textbooks in my department, but it looks like that's going to be at least two years away.

It's easy to blame government bureaucracy but the real problem is the combination of lack of empowerment and policy which discourages hiring qualified staff in-house. Most agencies have been facing budget cuts for awhile and there has been congressional pressure against hiring staff because hiring contractors allows you to campaign on having shrunk the government, you can receive donations from contractors, and few reporters will actually do the homework needed to note that "saved" positions tend to cost more once you factor in overhead.

Even if you do get permission to hire techies, the GS pay scale limits who you're going to be able to hire. There aren't all that many jobs at the top end of the scale and even fewer will be non-managerial spots which means that your sales-pitch for putting up with bureaucracy and political meddling starts with a significant pay cut for high demand professions. (This is the same reason why regulatory capture is such a problem – we'd be much better off giving the SEC staff 400% raises than having them make decisions about likely future employers when they get tired of below-market pay)

If you do manage to make it that far, you can do some interesting things. I know the CFPB runs a far more modern IT shop because they were able to start without years of legacy-blinkered culture and hire skilled staff directly rather than relying on contractors through a procurement process which basically legally binds you to the least functional waterfall process. It'd be really good for the entire government if that became the model in the future – hire good people, give them autonomy to get projects done and responsibility to deliver.
