The author seems to be assuming that all operating systems use the same implementation or have the same man page even for these random number generator devices -- they do not.

For example, on Solaris from random(7D):

The /dev/random and /dev/urandom files are suitable
for applications requiring high quality random numbers
for cryptographic purposes.
...
While bytes produced by the /dev/urandom interface are
of lower quality than bytes produced by /dev/random, they
are nonetheless suitable for less demanding and shorter
term cryptographic uses such as short term session keys,
paddings, and challenge strings.

In short, on Solaris, you can use either one although you are encouraged to only use /dev/urandom for specific cases.

Seems like an ipad is pretty close to what you want. If you could project part of the screen and leave some left for nav, new slides etc. then you could draw at will and be able to jump around slides without having to disturb the audience while you fumble around for it.
Did you bother checking what else it says and what the U.S.'s stated reason for not signing is? Or do you prefer to post ignorant sarcastic criticism?

There are two kind of classes: those that bring you up to speed; all the stuff there is found in textbooks or review papers.

And those that present wholly new ideas (research seminars, conferences,) where you can just read the paper or the preprint for details.

The only time I've seen something on the board that I really had to copy down to keep an copy of was exercises and their solutions.
Mozilla does a great job promoting open web standards and Firefox is the one of the best footholds the community and industry have against hegemony and stagnation online.

However other organizations can and do work towards the same goals. I'm one of the creators of Tent[1] which shares a lot in common with Persona (including some community members) but is more ambitious in many ways.

In the Persona AAR Mozilla identified several reasons for Persona's failure to gain adoption[2] including that Persona " can't offer the same [as Facebook Connect] incentives (access to user data)". Tent's primary purpose is as a user data store and also supports features like address changes automatically (which Persona never did).

We were fans of and friendly with the Persona team, but I believe the best solutions to these problems will come from teams that aren't afraid to think bigger than Mozilla's strategy at the time allowed.

The work of federated identity solutions will continue on Tent and other projects, many of which are probably better suited for a wide variety of users and products than Persona would have been. Of course none of us have (or are likely to gain) the level of institutional (or financial) support that Persona had.

Current source article title: "Lakota Indian Promotes New Digital Currency, Mazacoin" (there is a correction notice in teh source article.)

No one has adopted it as "legal tender", one guy is promoting it, and has duped a few news outlets (including Forbes and the WSJ) by issuing false press releases about official adoption by either the Oglala Sioux Tribe or the Lakota Nation. An article [1] linked in the corrected WSJ article notes (but the WSJ does not) that the tribe has denied that the person promoting it is even on their roles as a member; the corrected WSJ article does note that the member of the Lakota Nation governing council that they discussed it with had never heard of it and seemed suspicious of it.

I think nether has decided there are a group of A-10 fanboys who love the plane unconditionally. It has guns not missiles, therefore guns must be better than missiles.

C has no references -- 'type& param' -- so there is no debate. This is a topic exclusive to C++, and isn't affected by smart pointers, which overload all the pointer operators in order to act like regular pointers, only with some sort of lifetime management.

To better understand the importance of RAII, you might consider what some other languages offer to solve similar problems.

Consider a C example:

int f()
{
int ret = -1;

handle * a = acquire_handle(0);
if (a == NULL) goto fail1;
handle * b = acquire_handle(1);
if (b == NULL) goto fail2;
handle * c = acquire_handle(2);
if (c == NULL) goto fail3;

// use a, b, c
ret = 0;

release_handle(c);
fail3:
release_handle(b);
fail2:
release_handle(a);
fail1:
return ret;
}

Consider a C# example:

void f()
{
using (handle a = new handle(0))
using (handle b = new handle(1))
using (handle c = new handle(2))
{
// use a, b, c
}
}

Now a C++ example using RAII:

void f()
{
handle a{0};
handle b{1};
handle c{2};
// use a, b, c
}

These examples are mostly equivalent (Although the C#/C++ assume exceptions instead of error codes).

The C#/C++ examples are far more structured and less error prone than the C example.

The advantage of C++'s RAII over C#'s using statement is that cleanup is tied to the object rather than a statement. This means that RAII is both composable and non-leaky as an abstraction. You cannot forget to destruct an object in C++, and you don't have to care that its destructor frees resources. When you have an IDisposable member in C# you must manually mark your class as IDisposable and then implement the Dispose method yourself. Clients must also be aware that your class is IDisposable in order to use it correctly.

Ok, here's a solution: Private prisons are corporations. To ensure that they act in good faith towards the goal of a better society, instead of motivated by sheer profit, let us make a laws that compensate private prisons, not by the number of bodies they house, but instead on the recidivism rates. We should not be paying these entities to house humans indefinitely. Instead, motivate them to rehabilitate and return these people to society.
Entity Framework, when you modify an object it stores in a central location what the change was to be written out to a location latter.

It is performance wise infeasible to avoid that circular reference because it is very easy to pull back a lot of data from entity framework and change none of it.
Does your statement mean that one could actually turn off the randomness collector once the initial 256 bit seed has been generated?

It would make designing a one-time pad generator chip very cheap. The factory could print a chip, seed it, and the product would be done. Would you put your name to such product, making the argument that it would be fully cryptographic safe to use?
PowerPoint isn't the enemy. Poor use of PowerPoint is the problem. Bad presenters is the problem. People switching over to white boards won't make them better presenters, now they'll be communicating poorly in a messy unshareable medium.

The solution isn't no PowerPoint. The solution is teach people how to communicate. How to present to both technical and nontechnical audience. How to write an executive summary / elevator pitch.
Maybe I'm not following your response. What I'm saying is that there are reasons to use /dev/random at least after boot (to block for seed entropy). Saurik gives a real world example of the "cold boot" problem as other articles have done in the past. Are you saying we should be able to simply stop there and then just use /dev/urandom? If so, then why is the CSRNG re-seeded every 60 seconds? It would seem that there are reasons for doing so.
Do you know anything about changes in tactics related to MANPAD threats, then? I read some about the Soviet war in Afghanistan, where we supplied MANPADs to the rebels for use against Soviet helicopters. Reportedly, they didn't actually shoot down very many helicopters, but they were very effective in that the threat of them forced the helicopters to engage from much further away from the battle and move at higher speeds to limit their vulnerability, but also limiting their effectiveness.

I wonder if there has been an affect like that on the A10s. And I wonder if anybody who knows is actually allowed to tell us.
Awesome, thanks for the comments. I actually saw your blog post a few days ago.

I wasn't aware that 3 digit hex codes had less support. I had tested everything in Litmus and it seemed fine, but I've updated the examples anyway to use 6 digit color codes just to be sure.

I agree with your point on image buttons as well. We're planning on adding many more snippets in the future so stay tuned :)
That exact link (the Persona AAR) is in the blog entry. It's in the FAQ under "Why has Mozilla stopped funding new feature development on Persona?"
The next part is the funniest though...

As good as this gun would be as a rocket pack engine, the Russians built one that would work even better. The Gryazev-Shipunov GSh-6-30 weighs half as much as the GAU-8 and has an even higher fire rate. Its thrust-to-weight ratio approaches 40, which means if you pointed one at the ground and fired, not only would it take off in a rapidly expanding spray of deadly metal fragments, but you would experience 40 gees of acceleration.
This is way too much. In fact, even when it was firmly mounted in an aircraft, the acceleration was a problem:

[T]he recoil … still had a tendency to inflict damage on the aircraft. The rate of fire was reduced to 4,000 rounds a minute but it didn't help much. Landing lights almost always broke after firing … Firing more than about 30 rounds in a burst was asking for trouble from overheating …

But if you somehow braced the human rider, made the craft strong enough to survive the acceleration, wrapped it in an aerodynamic shell, and made sure it was adequately cooled...
... with a GSH-6-30, you could jump mountains.
I have done weak pointer logic, it is not pretty.

The "non obvious" part that makes it RAII is simply that the stack variable in question owns another resource besides itself. The stack variable is being used to wrap something else, be it a chunk of memory, a file handle, one or more other dynamically allocated objects, etc. The key in RAII is that when the stack variable wrapper goes out of scope, the wrapped resource (which is in addition to the stack variable) is deallocated, freed, released, etc.
Workforce Optimization Consultation
Name one language that got popular with no one posting/talking about it.
Sorry I was unclear.

I think we only had "misgivings" because the key we were generating had only relatively minor use in the product. Alas, I don't recall exactly what that was, and it's certainly possible, in retrospect, that we didn't care as much about the implications of using /dev/urandom as we should have. But that was pre-Snowden.
I find it interesting that nobody mentions iterators anywhere in this discussion. One of the main uses of pointers is to iterate through data. Pointers are the most basic form of iterators in C++. STL iterators are based on, and often implemented in terms of, pointers.

Most of the time it's because those people can't make the connection between the research and the "real world". The worlds are very blurred in my experience.

"A glance" is a good way to express it. I don't really care what I see, I would just like a quick gauge of how well-kept their code is. I think looking at the small things like frequency of comments, variable naming, parameter checking, etc would be a good basic indication of their style.
As a former Mozilla intern whom worked directly with Identity team on a daily basis last summer, I can say that this indeed hits close to home, though not unexpectedly so. I could see this coming. The Identity team has so many weird and wonderful things on the way for the broader Firefox audience that transitioning it to the community only makes sense.

I for one can't wait to see what the open source and HN community does with Persona and also can't wait to see what comes out of the Identity team as a result of this transition of focus.
Agreed. Now instead of people reading off of Powerpoint slides, they'll be talking into a whiteboard with their back to you, while you struggle to read their handwriting (and short of taking a picture of the whiteboard afterwards, you won't be able to review the notes).

I would certainly include defining a singular version to be under the power granted by standardize. Heck most standards are singular in nature. That isn't a stretch at all.

That only works for some very basic things. Maybe roads (I doubt it) and certainly not a lot of things such as National Forests.

Agreed. I recently had someone who refused to sign in (after paying for a subscription!) because they thought I was asking for their Gmail password. He ended up changing his account to a different email address specifically so he wouldn't go through the Google bridge.

Persona is a great idea on paper, but my outsider's perspective is that it has been very very challenging to implement in practice. The BrowserID protocol works great. User experience and login state management has been a bumpy ride.

My site (letscodejavascript.com) relies solely on Persona, so I hope it thrives, but I can't help being worried at this announcement.
If you're saying that the students in the other countries get a better understanding of the material, they would then also be better at taking the test. So, the whole base of your arguments falls, since you compared the way they teach in different countries and then concluded that other countries' ways were better and taught more. By your own logic, the US should follow the other countries ways if they want to achieve better scores..

I.E. the tests are not at fault, but it sounds like your education system is teaching things in a wrong and inefficient manner.

To provide some anecdotal comparison, here in Denmark, we also regularly test students. Nobody has any problems with this, the education doesn't lack because of it. So the problem does not lie in testing, but it might lie in what you test for, and how the teachers perceive what the most efficient way of teaching is.

If you test a child in the curriculum to check if they learned the curriculum, and they pass the test, is it not reasonable to conclude from that, that they have learned what they should?...
For cultural context, i live in germany.

Are you american and really think this is a sane path of action: "The Convention is unlikely to be ratified in the near future because it forbids both the death penalty and life imprisonment for children [...] threatening national control over domestic policy"

To be honest, to me this sounds exactly like immigrants to germany claiming a right to honor slayings because it's part of their culture.

If that's not the statement you tried to make, please clarify what exactly you think is the US' stated reason for not signing it.

Its not really that surprising -- survivability through sheer speed seems to have been largely abandoned in favor of focussing largely on stealth (see, B-2 Spirit vs. B-1 Lancer).

With the motivation for pouring money into moar speed gone, you stop getting moar speed.
Agreed, a thousand times over. I lived through the transition from chalkboard + transparency classrooms (high school) to whiteboard classrooms (college) to powerpoint classrooms (grad school). I've also taught with all three.

The real shock for me came later in grad school, when the undergrads (these were all upperclassmen) all basically expected that you'd provide them with the printouts of your slides, and therefore did nothing in class. They'd sit there, diddle on their laptops or phones, and then get cranky and exasperated when you'd tell them, "no, sorry...there are no slides. you have to take notes."

Learning is simply better when you have to write things down. You're engaging your eyes, your ears and your brain...and you're well aware when you're goofing off. I wish colleges would ban powerpoint in the classroom, but since powerpoint is an epic crutch for the lecturer as well, I have my doubts that it will ever happen....
> A hypothesis that's only true in an ideal world isn't useful nor is it meaningful in the real world.

You are not treating EMH like you should, think of it as a guideline not a hard and always true rule of life.

For instance lets say Telsa is trading for $100 and you think it is worth $50, there are two reasons for this, either:

* The market is not efficient and you should take advantage.
* The market is efficient and you aren't considering all of the variables.

In almost every conceivable case it is the latter. The answer for Tesla is probably optimism for the technology when optimism often drives prices above the otherwise expected value.

EMH makes you consider the market as the baseline, which greatly helps steer you towards what is going on.

Something makes me feel like that might be an uphill battle. The focus of the entire site appears to be a slick superficial UI. There is no attempt to consolidate data from various agencies into a uniform access format (say a JSON API or periodic dumps to a user-pays S3 bucket). The data is in XML or CSV or even XLS. The whole implementation seems a bit misguided, to be honest.
Powerpoint allows you to put text in the "lecture notes" section. This doesn't get presented, but you can view it with the file. Win-Win
if your teacher has a textbook that he follows okay, but here in France most teachers don't and you have to copy everything they write. And even if they have a course online, they will waste so much time just writing it...
completely disagree. my calculus and algebra professors never used powerpoint on any lecture and they were extremely well prepared. those were the best classes on the whole uni.
