We desperately need someone to configure Android with LUKS/dm-crypt, which theoretically shouldn't be such a huge leap since Android is based on Linux (I know nothing about Android-specific kernel divergences, but would be interested to know if device-mapper is badly broken in Android kernels).

Another interesting project would be a service that sits on your phone and automatically encrypts all of the automatically synced data, so Google only received encrypted data and your phone transparently decrypted it upon demand. This one would probably require much deeper work than making device-mapper run on Android Linux kernels.

I am grateful to Google for making an open, decent phone system so that this kind of stuff is made possible. Think about the options we'd have if iOS was the only smartphone on the market.

People need to accept that without strong encryption, any and all of their digital storage is open to adversarial or even accidental perusal, and that they should have no realistic expectation of privacy without correct application of cryptographic techniques. This is true across every form of digital storage: mobile, desktop, laptop, cloud, USB stick, etc. Encrypt or suffer.

Why on Earth would he use hma when tor is readily available and far better at hiding your nefarious deeds? At the very least, if you live in the US, use an extranational vpn. Take some of those "hacking" skills and use your neighbour's wifi, wiping the logs after each session. For the FBI to have an IP address that leads back to you means you're incompetent.

The lack of technological sophistication from these guys just further highlights the negligence on the part of the victims. If someone who knows this little about security can infiltrate your network and steal your secrets, then you have serious problems.

Lovely bit of work for just 10K. The only criticism I would make is about the zoom. Not sure that the controls should enlarge as well.

Is there a betting pool where I can put a few quid on you winning the contest?
> Thanks for the excellent introduction to my next topic: An important function of programming education is to teach people which things other people often find difficult.

Why? In my mind, managing student psychology is more important than conveying meta-facts. If a student will learn slower if you tell them that other people find something hard, then don't tell them that. As a bonus, the meta-fact might become less true.
Love the carriage return. Love the music in the video. Love the whole project.

This looks like it's going to be a great language. Compiling to LLVM should mean that it does tall call optimization, which is great and also means that integrating with C/C++ should be fairly easy.

The only thing it's missing that I'd like to see is support for CPS conversion like streamlinejs does. Even if it supports growable stacks that start at 1KB, with thousands of threads CPS conversion is still more efficient. Having said that, seeing as they are writing browsers, not servers, I can see why it's not a priority to do this.

CoffeeScript and SASS are awesome, but when asked, nobody seems to be using them yet. Is it all just hype?
I'm guessing Facebook Timeline triggered this sell?
I wonder if any of that has to be said at all? What if a lecturer did not set this prejudice upfront at all? However helpful emotions are in the learning process, saying "this is tricky" or "this is easy" is not going to help.
Instead, play on other emotions. Explain the theory, show real life examples, simple tricks, stuff like that, surprise them. But don't say "this is hard" or "this is easy". Let them decide.
Granted it's not groundbreaking but it's attempting to make UUIDs "better". For computers it doesn't really matter what an identifier looks like (minus memory to store long strings, maybe). For users, it does matter.

Long UUIDs are just an artifact we've grown accustomed too. By no means are they the ideal solution.

The type of namespacing OpenPhoto does doesn't apply to everyone either. Sometimes you do need a UUID that isn't namespaced. Sometimes you don't.
UGG 5733 Suburb Crochet Tall
Sometimes I wonder why do all the programming language designers prefer to invent several different syntaxes for one concept...

From the third slide: we can see two different function definition syntaxes, a "normal" style and a "ruby" style. I really like the way of JavaScript, CoffeeScript and OCaml that have a single unified function syntax.

Also on this slide: why have a special syntax for importing submodules from modules/crates? Again, CoffeeScript excels here, an import is simply a variable declaration:

{int, vec} = require('std')

Furthermore, it has always bothered me why generic types use <> brackets. I can understand it in Java and C# (where types are declared before values/functions), but in Rust, it's really unnecessary to introduce the 4th type of brackets into the language (apparently, they used [], but latter changed it to <>... I would really like to know why.)
Feynman said it in reference to top-flight physicists explaining their research. I can certainly believe that CS teachers would know the words well enough to recite them to their students without having a true understanding of what they were saying.

As to why they don't understand - well, who taught them?

It was a huge gamble bringing a successful enterprise software CEO into a media company and it failed.
You can ask that question about almost any leader, especially non-founder CEOs -- were they just sitting on top for the ride or did they do it themselves.

What prospective should I pitch my marketplace business from to investors?
I'm building a marketplace that has two sides: users and businesses. The businesses benefit from the marketplace because they can sell things. The users benefit because they find things they need.

With this type of business, do I need two separate pitches? One for businesses and one for users? If so, which pitch do I give potential investors?

Via sues Apple for patent infringement over 'microprocessor functionalities'

Yes I would say kqueue, the interface, is superior to epoll. Kqueue allows one to batch modify watcher states and to retrieve watcher states in a single system call. With epoll, you have to call a system call for every modification. Kqueue also allows one to watch for things like filesystem changes and process state changes, epoll is limited to socket/pipe I/O only. It's a shame that Linux doesn't support kqueue.

But as awesome as kqueue is, OS X apparently broke it: http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod#OS_X_AN...
It indeed is the standard deviation.
I didn't know what Pixel-Perfect is and your README didn't tell me much about what Perfect-Pixels does. I found a short description of it in the project description, but you definitely should add it to your README and this post.
I'm not making a close analogy and I'm not saying they should shut it down.

I'm just saying Apple will know when the classic isn't worth the time/energy/shelf space and I wouldn't be shocked if they announced this is the case in weeks rather then years.

And I guess I'm making a wild guess as to how they might keep an HDD based idevice relevant although I don't think that's particularly likely either.

There's the issue that digital data is much more valuable (and/or damaging). Nobody is going to break into an office building to steal their filing cabinets in the hopes of finding enough info there to guess someone's mother's middle name and subsequently hope to steal their credit card or bank account. Being able to effectively search, filter, and map against other sources makes digital data particularly valuable. In essence, digital crime scales.

That said, I'm not sure I agree with your claim of the ease of digital versus physical security - physical security is something we're fairly good at, having had a few thousand years of practice. I suspect the number of bank robberies in which human factors (The physical equivalent of rubber-hose cryptanalysis being 'pointing a shotgun at the manager') massively outweighs those that were exploited by technical means.

That's not to say that they weren't negligent in not even taking the basic precautions that are common sense to anyone working in the field, and even many who aren't.

Looks to be a very interesting idea. In fact, I do want one. Buuuuut, I'd have to wonder with those prices for the full models and DIY kits if he is not overcharging by several hundred dollars. True, you're buying a piece of tech for its look and feel more than functionality, but as a guy who's actually bought, played with, and used old style typewriter, $700 is a bit much for anyone.

Could any enthusiasts (I consider myself an amateur) weigh in?

I hear it all the time, mostly from Ubuntu and Debian users (we have millions of users, so I get an earful of just about every strongly held opinion out there), but occasionally from SUSE and FreeBSD users.

It tends to be sour grapes about Red Hat and derivatives being the most popular. That may change now that Ubuntu is approaching similar popularity on servers (which is the sort of Linux users I interact with). But, I also hear quite a bit of bellyaching about RPM and yum, which I can't fathom...I prefer them to apt-get/dpkg, though both are perfectly acceptable and I rarely complain about either.

But, I hear a lot of complaints about just about everything. So, maybe Red Hat just gets the biggest share because they get the biggest share of the money in the Linux distro market.
What doesn't add up? It's an auction.

My plan is to open source it on Github or something if no one thinks it's worth 10k.

I am not trying to correct but clarify what you mean by unified syntax.

In OCaml you can say let rec func = ... , let func = ..., let func = function |... | _->... and let func = fun ... -> ... Now I find that each of these variations make good sense and would call them unified facets but they tripped me up many years ago when I was first learning the language.
Actually I would run ss over the netstat for such high concurrency connection as netstat hits /proc/net/tcp and it's quite slow. However, you need to have the tcp_diag module loaded otherwise it falls back to /proc/net/tcp.
Two typos in the first sentence:

interpretation of software as language and therefor patentable

Should be "therefore" and "not patentable" or "unpatentable" or "not subject to patents".

That's true, and there is also let func a b c = ..., and most of these are just syntax sugar, mainly useful at the module level. The important thing is, though, that the function declaration syntax is the same as the "inline" function syntax, I can easily say:

let f = function 0 -> false
| 1 -> true

use (f)

and then refactor the code into

use (function 0 -> false | 1 -> true)

That's the consistency I'm talking about...

I'm going to drag out another cstross quote (from Accelerando[1]):

"[...] his suitcase is on its way to Mombasa, where it will probably be pithed and resurrected in the service of some African cyber-Fagin. That's okay by Manfred — it only contains a statistically normal mixture of second hand clothes and toiletries, and he only carries it to convince the airline passenger-profiling expert systems that he isn't some sort of deviant or terrorist"

At what point is it going to be statistically abnormal to not be sharing the minutiae of your life in this way, and what are the consequences to anyone who wants to retain some level of privacy? Will they be required to maintain some sort of statistically-average social network profile, occasionally updating it with something plausible?

Dragging this offtopic a bit, but is there any reason why YouTube couldn't add an upload flag of 'audio optional' so that in situations like this, it just muted the audio stream in the specified regions?

Then, if someone owns the copyright to the soundtrack, they file a complaint against only that, and the video remains up. Or, they can file against the whole thing, and have it completely blocked (assuming sufficient rights).

Yuck, embarrassing.
My entrepreneur friends and I have many apps like this that were learning experiences or that never materialized into anything. I was having a conversation with someone just yesterday brainstorming with them how to wind up a project like this and helping them to get past emotional attachments, sunk costs, etc.

The thing is that when someone buys an app you've finished, but that isn't generating revenue, they're buying both an opportunity and a problem.

The opportunity is obvious - maybe you can turn it into a money printing machine.

The problem is the developer cost to maintain and improve the app. Unless it's a complete business that's generating cash already (in which case it would be worth more than $10K), it's going to cost significant $$ for another dev to maintain and build on it.

Most dev salaries are around $50k to $150 per year. But lets assume you offshore it, find some killer talent and pay them $20k per year. If it needs 2 years of work and growth to be successful, that's 400% more than the $10K it costs to buy it in the first place. [Ignoring time value of money]

The point I'm making is that the $10K price tag is arbitrary to a buyer because what they're really getting into is a much larger commitment and quite a bit of risk.

So what to do?

I don't have the answers but I'll throw out 2 ideas:

1. Open source the project and recruit your friends to keep building it. Use the publicity and interest surrounding it to drum up consulting gigs worth more than $10K and funding and credibility for future projects and businesses.

2. It might not be a home run because Facebook has done it, but spend an additional 20% of the time you've spent so far to put in place a payment processing system and charge for the service. You may make more than $10K per year in recurring revenue. Just because Facebook did it doesn't mean you can't too.
