It's worth noting that 0MQ was developed as a library for HFT/algorithmic trading applications. In those environments, TLS isn't necessarily a requirement because it's a closed network. If you need TLS so your trading app can talk to the ticker-plant securely, you have bigger problems than you think.
From what I understand, it's fairly expensive. It's tough to make a profit on a phone when the battery costs $500. Costs are surely coming down but I think we'll have to wait before it hits the mass markets.

This is one of those priceless documents that served me well, and which I have recommended to many others as a great starting place.
Im not clear on why you get better features.

I have a webapp that I built, that utilizes rackspace's API and chef. I have a chef server that I use for all my configuration management, I have a Rails app that I use to talk to my chef server to manipulate machines, or rackspace's api to spin up machines, and I am building "triggering" into it (low disk space, high CPU do X). I am able to change IP addresses, spin up a machine with a specific stack etc. Granted this isnt the default chef-server, but the ability to do all this stuff, and not be locked into AWS is there.

I agree with your POV and the decisions we have to make as a result. That said, users should be expected to learn computers if they want to use them. If not, they shouldn't be allowed to use them. Same policy I'd have with a buzz-saw in a shop.

So if you fall for email phishing attacks despite training, then you shouldn't be trusted with mass email rights. Likewise, the admins have an obligation to control those resources, and to train users. (If that's too hard to expect, then we need to find out why.)

Point is, users should get the blame for their fuckups-- when they fuck up. It's not an all-or-nothing thing.
How is dumbing down the world better than teaching best practices to people who will shape the future?

20 years earlier, wouldn't you have expected an office secretary to not send postal mail to everyone in the city?
Or give the cabinet keys with the petty cash to anyone who dressed like his/her boss?
I like data driven stuff. Though there's still a DSL. This is a large reason why I made http://ansible.cc, as I wanted the actual description of the policy to be data as well.

I used a similar technique for a less frivolous task. I had script dumping data in text format, and wanted to refactor it. I committed the result and could refactor brutally step by step, running the script at each step and reverting whenever the dumped data showed some diffs.
Any demo website out there? Seems to be a great project.
I think the editorial doesn't make clear exactly what "online courses" mean.

There are two ways to interpret the phrase:

1) Normal high school students go to community and technical colleges and possibly take online classes. In that case, you are correct

2) In washington state, you can actually take online classes in high school and even k-8 (k12.com) and my understanding is that there have been studies on k12 students and their performance in community and technical colleges as a function of whether they went to a physical or virtual elementary and high school. I am guessing they are referring to the latter (where other studies -- take a quick gander at google -- do draw the conclusions that the article refers to as "well known")

Unfortunately I couldn't find the study that the article is explicitly referencing.

The official Basecamp app for iPhone
Sunrise has really taken it the extra distance to make for a compelling, easy-to-use calendar app. There is no doubt that the native iPhone calendar is mundane, but to beat any native feature of the iPhone, an application needs to demolish it in its functionality AND UI. Mailbox seems to be doing just this to the native Mail on the iPhone and I think Sunrise will do the same to Calendar.

what's a "macro"?
They also have (on average) ~12g protein and 1.5g fat. At a little over 20% of the carbs you need per day, it's not going to ruin your diet, but could have an unhealthy effect on blood sugar levels in some people [http://www.phlaunt.com/lowcarb/19060174.php]
I feel for them. I attend an IT-focused university that has both hardcore techies (computer science and such) but also a lot of non-techies (communication, UI design, etc.)

We frequently (at least once per month) get a phishing e-mail asking us to reply or click a link and provide our credentials. For anyone who has attended the university more than 6 months, there will have been at least 3 e-mails from the IT-department telling people to not ever, in any way, give out credentials. Yet, for every phishing mail we get at least 3-4 accounts get compromised (out of ~1500), and more would get compromised if the IT department weren't quick to block traffic to the offending URLs. And again, this is in a crowd that should be somewhat unfavourable to scammers (as most of us know and can recognise such attempts).

You can try to educate your users, and you should, but just know that it only minimizes the risk, it will never, ever nullify it and if they can send 1 million e-mails from just 1 account, then it is practically a dead-end in terms of stopping the scammers. I can completely understand why they are blocking Google Docs, it's a matter of settling for the "lesser evil" solution.
That book only applies to you if you have a very flexible schedule.

They're probably not going to test gun control as much as the press thinks. Calibrating cheap 3D printers is hard, and chances are it's going to take quite a bit of tweaking to print off a reliable magazine or other part on a new printer. I can easily see would-be spree killers getting stopped mid-massacre because their misprinted magazine jammed.
No, because it is a good name.

With 3d printers you are printing layers, like a conventional printer, but one over the others. In fact you could even use the same heads, I could 3d print wax with my printer and an Epson Inkjet head.

I wonder, why doesn't Amazon venture into actual utilities business? As in making their own power plants(nuke/solar/whatever), and renting power out?

I did remember reading about Bezos investing in a few energy companies, but nothing about Amazon.
I'm hoping for this too. Especially somebody who has used both exhaustively. At first glance the architecture of both seems to be pretty sensible, clean, minimal and good in all the ways that puppet isn't. I half heartedly picked salt based upon the following:

* More commits in github.
* More pull requests in github.
* Main website is ranked higher by alexa.

However, after using salt for a short while, I ran into a couple of problems (no mercurial state, no ability to specify versions when using a pip state), which ansible seemed to be able to handle.

So, I don't know... salt seems to be more popular. A bit. That's all I can tell.

Considering he's modeling the drive writing at the full SATA 3.0 interface speed for the entire lifespan of the drive, continuously, amplification shouldn't affect his numbers, only the perceived throughput the user receives under this workload. He mentions this is already faster than the drive can actually write: "the maximum link speed for SATA 3.0, which happens to be larger than any other relevant interface or drive speed so it's a solid upper bound."
It looks like every comment here is picking apart the reasoning of the New York Times editorial kindly submitted here. The editorial includes a paragraph relating a rather troubling factual assertion: "A five-year study, issued in 2011, tracked 51,000 students enrolled in Washington State community and technical colleges. It found that those who took higher proportions of online courses were less likely to earn degrees or transfer to four-year colleges. The reasons for such failures are well known. Many students, for example, show up at college (or junior college) unprepared to learn, unable to manage time and having failed to master basics like math and English."

Taking the statement "Many students, for example, show up at college (or junior college) unprepared to learn" (college-level subjects) at face value, which I will because I have seen multiple sources that report the same phenomenon, let's see if the editorial makes sense. The editorial does NOT say that anyone has done a treatment/control study of taking beginning college students of matched preparation and then having some take online courses by random assignment while others take brick-and-mortar courses by random assignment. It is that kind of study design

http://norvig.com/experiment-design.html

that would be necessary to blame the online nature of the courses for lack of "success" (completing the course and going on to another course) by the students in the course.

If bad preparation of students before they attend college drags down the success rate in college courses (as seems plausible to me), then the policy response is to research better preparation for K-12 students. Fortunately, many researchers are working on that important issue.

http://www.gatesfoundation.org/united-states/Pages/measures-...

But if an online college course makes the difference between a college-age student attempting to take a course versus not attempting the course at all, and is meanwhile less expensive for the taxpayers who subsidize higher education, let's give the online courses some more tries and attempt to refine and improve those. This doesn't have to be an either-or choice. Students who are adults attempt to find college courses while fulfilling their other adult responsibilities, such as earning a living. Sure, let's improve courses for learners at all ages. But let's not reject an entire learning model if it is chosen willingly by some students who may not be able to choose any other.
> Our solution is simple. If you want to send out an email to everyone, send it to a central authority that can approve the sending.

It sounds like all you are doing is regulating access to some sort of all@university mailing list. How does this solve the much bigger problem of spammers using compromised accounts to spam Gmail/Hotmail addresses, which then end up getting the university blocked? And even ignoring that how does it prevent people from just looping through a list of your university's email addresses and sending them one at a time?
This is truly disturbing, I really don't know what to say. What is the point in a war, where people feel it is ok to become monsters like this?

Am I Stupid Again?
A couple of years ago, say around 3 years ago, I could not watch movies anymore. Every single movie was quite predictable IMO which completely ruined the experience.

This let me to believe that that phase of my life were I could just vegetate all day in front of a TV watching films was over.

I decided that it was either two things, I'm smarter now, more experience, or the population is simply stupider. I did not think that the films were worse then before, is just that I'd seen so many films that no new films felt original. For somebody just getting introduced to films, say a child, they were great films.

Lately though I've started to see a lot of really good films. At least films that have kept me entertained. And although sometimes you can still predict that the hero will win and how he will win I still find the films interesting.

This has let me two believe one of two things, I've become stupider or I was simply going through a depression phase of which I'm just becoming aware of.

By the way, two examples of really good films that I've seen are "The Last Stand" and "Jack Reacher".
Just saw a trailer of "The Internship" and though it was hilarious.

So what does everybody else think? Has anybody gone through something similar?

Better, but scrounging up a few million pounds for dongles, plus the non-stop cost and effort of replacing lost and stolen dongles, is not easy for a university, no matter how famous.

Additionally, what OSes will these dongles support? Would you rather "Oxford University bans Windows XP"? or "Oxford University bans iPhones"? etc.
Macronutirent. Basically it means one of either fat, protein or carbohydrate. Many diets will have you set a calorie goal, and then suggest a guideline what percentage of your calorie intake should come from each macronutrient group.

I don't think it is.

Basically if you get your car from the dealership (AWS is great esp for EC2 and S3), you don't have to buy the tires from them too.

What I saw from the video does look interesting, but in the end, if you are going to have to edit your configuration management recipes in git, and then you're going to have the same choices to make about what tool is best for you. Whether that's Chef or something like http://ansible.cc -- this is what you are going to pick because it's what you're going to spend most of your automation time in.

I also suspect Amazon will feel that people may want to bring their own tools and will add more options over time.

I got a Dell Latitude E5520 (http://www.ubuntu.com/certification/hardware/201011-6894/) about 18 months ago. The screen is better than what I could get from Apple at the time.

I wish I had gotten a Mac Pro instead, mostly for stupid hardware details like the sensitive power contact (the mac magnetic one is superior) and the too sensitive trackpad. Apple is the only competition for Thinkpads, imho.

If I had gotten a Mac I planned to run Linux in a virtual machine all the time, mostly because apt is superior to the native alternatives.

Why is that not an alternative for you?

And on the Fourth Day, God proclaimed "Thou shalt have the ability to use inline assembly in thy C/C++ code for performance-critical tasks".

I can think of absolutely zero reason to write an entire program in x86 assembly, let alone any other kind of assembly (GCC spits out some pretty optimized code for my little Atmel MCU)... It's a lot nicer to write everything in a high-level, and then write any performance specifics in inline assembly.

The really cool thing to see is how other newer languages have adopted this scheme (e.g. PyASM for Python, or the ability to edit the instructions for interpreted languages that run in their own VM). And as always, great power comes with great responsibility ;)
Calibrating cheap 3D printers is hard right now. That doesn't mean it always will be. The good ones will get cheaper and the cheap ones will get better.

It used to be hard to get a computer to use a new paper printer at all. Now it's almost always plug-and-play.

You could imagine a 3D printer that prints test objects, scans them in great detail to find defects, and calibrates itself accordingly.
This is YC. The answer to "can't get a job?" is "create one - start a business." Nobody (broadly speaking) is going to run background checks on a guy (off the top of my head) washing cars at customers' homes, recycling-for-pay whatever he can, running low-cost courier, clean the grounds of the aluded-to apartment for cash, etc. The library is thataway, providing an education in anything you want for free (don't confuse education with certification).

The warnings about nanomaterials are about their applications, not their mere existence. (The rational warnings, anyway.) Graphene is just a form of carbon, like graphite or diamond, neither of which is thought to be particularly hazardous.

There also exist hybrid supercapacitors, which use a chemical reaction but act like capacitors. The best use of high-power capacitors is not as a replacement, its as a supplement. Current technology is not quite sufficient, but ideally it would mean that anything under a 20 minute drive could run off just the capacitor, which could(with sufficient infrastructure) charge in under a minute. It's not quite filling up on gas, but its closer.

I would like to see more investigation into turbine powered cars again, it may be more feasible now to build a car like we build trains (A prime mover generates energy for locomotive motors). I think the best way to transition from gasoline to electric would be to take advantage of existing infrastructure and make hot-swappable battery units. For medium drives you use batteries, which can be switched in a garage with a capacitor bank for short drives, or a unit with a small battery, a helicopter turbojet and a gas tank (Which, ideally, would run at a higher efficiency than an ICE).

The reason we haven't used turbines in the past as far as I know is mostly the start-up times and inability to idle. They don't really slow down, so sitting in stop and go traffic you engine is basically still on full blast. Ameliorate that with a battery and you're good to go, hopefully.

That's true today. Is it true in 2023?

I think there's some failure of the imagination here. 3D printing as we know it today will soon be only one tool in the automated arsenal. As robotics improve and 3D printing improves, the idea of a fully automated shop that fits in a reasonable size is not silly. You say you need a lathe to really make a gun? OK, fine, I tend to agree that current 3D printing techniques will never really make you a decent barrel... but what the stopper on a robotic lathe, or other robotic tool for building barrels? There isn't one.
Every cloud-based email service "scans your email" and does it a lot. This is mandatory in order to:

- Junk filtering, fishing protection and other security protections; all impossible to implement without deep scanning, analysis and correlation (this last item is important: some information extracted from your email is combined to information from other people's emails, in big statistical models and fancy machine learning jobs).
- Index content so you can search it (unless you want to only be able to search by subject and other headers... no, 1988 called, wants its Eudora back). Bing.com may not include results from email, but this is irrelevant, Outlook.com certainly has full-text search so there's indexing.
- Implement all kinds of cool stuff, e.g. Google Now right now shows that my last Amazon order has shipped, a single click on that shows the USPS tracking, how cool is that. Or more modestly, integration with other services from the same provider or from others such as cloud storage, office apps etc., or even simpler features like Outlook.com's ability to automatically sort email into categories, I doubt very much they can do it only looking at headers. (Even if they do, in many cases there's enough private info in headers that just not looking at the email body shouldn't reduce your paranoia.)

In the big picture, the extra scanning for ad targeting is really a very minor part of the whole. So it all boils down to discussing whether you prefer targeted ads or untargeted ads, and whether you trust the cloud service to protect the private information used for this. Notice that this same potential issue exists for all functionality above, not just for ad targeting; so if you don't trust GMail as a matter of principle, then you shouldn't trust Outlook.com either.
