There's no maximum length - only a theoretical maximum set of hash numbers before you have collisions.
So, an md5 hash has 128 bits of length, ergo 2^128 is the set size of hashes. That's best case. in practical terms you'll probably hit a collision before then. But I wouldn't worry... it will take a decade or two..
You can't take a tatoo off without pain and misery... Thirty years from now that tat is going be ugly as crap Possible infections, ink poisoning, skin rash & allergies Loosing a promotion, all sorts of other inequalities...
You can always change a shirt, throw it away, make a new one, change your mind... whatever. It's true that a tattoo says/means nothing these days, but sometimes it does.
And if you do get a tat, make sure you don't have to wear long sleeve shirts everyday - what a pain!
You are correct - the chip by itself (in its current incantation) is simply a crypto chip with limited capabilities.
However, what you're failing to understand is that you won't have a connection to the internet without passing a series of cryptographic tests, which have been outlined in TPM documents.
The biggest problem with this sort of arrangement is that you simply can't authenticate humans reliably, either by way of signup, policy or simply magnitude of scale. People steal credentials regularly, aka identity theft! Secondly, the cost of implementation would be astoundingly large... building authentication systems securely, deploying POP authentication points across billions of connections and safely transporting and storing said information would take decades.
I should know, we spent 3 years building the most secure commercial internet authentication system, with a 5 site redundant cloud of authentication services. 3 of 5 sites were necessary to pass an authentication, so we could handle two complete site thefts, or two complete site disasters and still authenticate safely (auth material was split utilizing a secret sharing algorithm). Each of our data sites were military-grade EMI/Faraday cages, under separate corporate ownerships.
In other words we spend millions on building the easiest & safest way to authenticate a user on the 'net, with most of that on auditing, code reviews, facility buildout etc...
And nobody wanted it!! Not for any price... not even for 50 cents/user a year!! Banks said users would NEVER type in two passwords,... HA!
They're everywhere! Sure, lots of people say they're writing C++ code (or, C code wrapped in C++), or application development. A lot of C development is OSS too - there's paid work in that area as well. There's TONS of maintenance work, especially in specialized industry controls, monitoring, whatever.
In other words, it's all around you - just shrouded in mystery. Not many people advertise new C development, but oftentimes it is just a another tool in a developer's arsenal.
I spend about $500 a year on music, and I'm really happy I can play it anywhere, on any device I buy, and without any hassles. Anyone arguing about the price, availability or quality music is just being an ass. Those that want uncompressed FLAC can pay the extra couple of bucks or buy the CD and rip it themselves - that's the price of being an audiophile.
I think most of the pirates you see online are either kids, people looking to make a buck off advertising, or foreigners who can't reasonably get your music because of language, lack of credit card or censorship barriers. Perhaps your missing a market opportunity by not having a way to sell to foreign markets, or maybe you could develop a second-tier market for advertising-paid revenue stream through youtube or other sources.
Anyway, use whatever tools you have to develop a rapport with your customers AND your pirates. Deals, promos, special cheap-o gifts, tours, bookstore signings - I dunno. But if you've got people watching then you have an opportunity to make money. Best of luck!
Sorry to say, but RTMPE has been broken for a while, originally as it was badly developed, and now using man in the middle type attacks - http://rtmpdump.mplayerhq.hu/ .
I agree that DRM can work for a limited time, or for a limited target size quite well. But with the current stat-of-the-art in cryptography, DRM will always be breakable. It's simply a game of hiding the key, and always will be.
GMO corn and soybeans are regularly found crossing into other fields, sometimes miles away... you can't stop the spread of pollen.
I agree with the speaker on many points, but the honest truth is that humanity is rather poor at predicting long-term dangers in products. Radium, mercury, benzene, tobacco, asbestos and PCB's were all thought to be minimally safe, or containable, or easily managed.
Food is a basic necessity for all humans, and I think we should be making better crops, more nutritional foods, and increasing the sustainability of farming and ranching. But honest labeling should be mandated to allow consumers to make informed choices. Making a bad choice is allowable.
I propose that every website which handles private data (credit, ssn, health, etc) should be integrating these kinds of tools into normal test procedures, both in development and on production mirrored sites.
The only thing this tells me is that investors are very slightly more confident in Apple's future.
Apple has a good business model for the current market, a vertically integrated company is well suited for fluctuation during violent market turns because investors worry less about shortages, missed financial targets and product competition. Microsoft is *hardly* moved by this in reality, though, and still makes most of their money on business licensing - and they are doing fine. MS employees are still having the private jet weddings to the caribbean with ice fountains flowing with rum.
Music and fashion are closely related arts today... nothing is obsolete - only improved, molded differently, passed on, or simply forgotten. But two hundred years ago fashion was not considered an art, it was considered a trade (tailors & dressmakers) until Charles Worth began labeled clothing in 1858.
Secondly, much like today's concern with biological, software, and business method patents the legal landscape was still not set in stone, legal precedents were set based on the public good and which make little sense these days. Suffice to say, America had a huge industrial capacity around 1870 to produce garments and textiles and IMHO didn't see any need to sour the growth of exports with legal problems.
Thirdly, America was rather anti-copyright and very anti-corporate until the mid 19th century due to the history of mercantilism. Trade, manufacturing industries, and exporters did not favor adopting restrictive laws which would grant legal rights to competitors domestic or abroad until major innovation and invention became worthy pursuits much later on.
So really it's just bum luck and bad timing for fashion and shoemakers.
You know who those people are, because you exchanged keys with that person. If you host your data on your own server, or ostensibly, at least the links to that data on another server - then you can control who gets there in the first instance.
Of course, once they have given them a right to a copy then they have it. That data could be kept encrypted with your key, which they would need to retrieve to view it again - but there's no guarantee there as that is essentially DRM.
Well there's competing interests here... you really need to test phones out in the field, across as many networks as possible. After all, a class action lawsuit, bad publicity and lost sales is probably far worse than loosing a few devices.
The problem with ultra-tight security is that people get lax over the years. A basic study of armed forces long-term defense plans reveal most of the common issues.
Property can be seized during a drug raid... in which case it's likely auctioned. Also, if your car is towed, it can have a lien put on it by the towing/storage company in some jurisdictions. But that would take some time... a long time.
Perhaps you misunderstood, my reply was concerning "learning through breaking" And yes, it is a "radically different philosophy." Giving kids things to break and expecting them to fix it is not mainstream. Our culture centers around healthcare, help centers, repair facilities, Genius Bars and Geek Squads. There are those who fix, and those who don't.
Toys are thrown out when they break in most households. Give them a repair kid and see what happens may be an interesting endeavor for them.
Your point concerning the development of childhood interest in subjects has many different variables. Traditionally, children learned the skills of their parents through shared work and play. My statement mostly concerns my own aversion towards "couch potato" living, whereby our interests are mostly confined to industrially produced culture.
Many homes are two-working-parent endeavors and naturally gravitate towards a stasis of ideas. Good for you for going above and beyond and building your child's character and exposing her to the real world.
The capabilities aren't an issue at all - it's just fine for movies, games, music and web surfing. It doesn't have hinges, no keyboard to break, and it's dead simple.
It's a consumer gadget, not a PC. I bought a netbook for my daughter and threw on perl and a C compiler... but that's probably not typical.
I don't disagree, it's just a radically different philosophy... Bored childhood leads to inventive personalities and self-intuition. But, sometimes it's nice to play a game too...
I don't think it's a sign of the end-times... it's a leisure device, it's instant-on and easy enough for kids to use without messing things up.
These people already have a computer for the heavy stuff... Most people just want to google a term, play a quick game, or set the kids up in the backseat for a movie.
No, they snort the noxious gases from a chasm and quack. Using the power of Oracle 13i and a huge dataset of duck calls, they are able to manage a software empire. Recently Oracle, announced the procurement of the Sun God Ra, after he defeated Osiris and left Isis searching the river for his missing uh... firmware.

That's an awesome system you've built... thanks for sharing!
There's a few hundred million people within 500 miles of the border. I don't see limited market as a possible problem.
You know who those people are, because you exchanged keys with that person. If you host your data on your own server, or ostensibly, at least the links to that data on another server - then you can control who gets there in the first instance.
Of course, once they have given them a right to a copy then they have it. That data could be kept encrypted with your key, which they would need to retrieve to view it again - but there's no guarantee there as that is essentially DRM.
You're correct - it really depends on how long someone lets it sit there, where it's at, and the jurisdiction.
It's working.. look at the battery bar graph on the bottom - it flips between 2% and other values @ 0:55.
