Keepass? That is an... err.. unfortunate name.
Robots dehumanize war, but if war shifts away from human casualties, isn't this a good thing?
Will drones ever be cheaper than training a grunt?
Cryptography is merely the study of hiding and unhiding information. It doesn't secure information. Security is about securing information from unauthorized access. These guys attacked the security of the device, probably through the protocol or through insecure hardware.
If the crypto itself (probably AES-256) had been broken, the NSA would have had some big problems on their hands due to the fact that the same crypto is used in the publicly-available Suite B algorithms.
Also, doctors and dentists are asking patients to sign binding arbitration agreements. Be VERY wary about this, as functionally it is much worse than limiting public commentary.
1. If this doesn't catch on and people want it to continue, this could be a significant ongoing cost for running this project above and beyond allocating what people might think are one-time NRE charges. None of this appears to be detailed enough on that site so I'm not sure how far they've thought through this. Who are the target vendors, and have they tendered bids? Costs vary greatly, and I'm not at all ready to throw money when there appears not to be an "open source" plan with sufficient detail to make this real, nor with open listing of the credentials of the individuals involved. If you're gathering up to $250k for a project and you want my money, I had damned well better know that you're able to execute and that you have a real plan and definitely not just an FAQ.
2. How did they define the product? Is it based on market needs? If so, what markets and where is the information on said markets? If it's for hobbyists, I get that, but did anyone do even a rudimentary survey to say how many timers or UARTs might be necessary, whether they should embed an MMU so you can run a more advanced OS, or what the max CPU clock speed should be? If *I* am going to put my money in it, then why not ask *me* what I want? And yeah, I know I can contribute, but how have all of those contributions been managed, organized and synthesized into what is being built AND make it sufficiently relevant for enough time that this would be worth doing before technology moves on? I don't see a single place for that around their site.
3. Frankly, why bother when there are many other vendors such as Microchip who offer 32-bit micros with fully-documented architectures and better capabilities that you can run Linux on? I know, I know, this is what open source is about, but we're not just talking about someone's spare time on a machine they do other things with; this is a real product with real implications. I seriously don't buy how they're going to change the industry since the successful players in the industry guarantee supply to their customers.
I know I'm going to get flamed and down-voted for this post, but the open source hardware world is much tougher than the software world, and ASIC designs are steadily dropping because ASSPs are taking their place. I think people's efforts need to be focused on software, and this is coming from a guy who's been on Slashdot more than a decade with a hardware background (and hence my name) and has switched to the software and systems world...
Watchmen wasn't too dissimilar to the bittersweet ending of Sin City. You liked the characters, but most of the "good" (read: likable) guys actually die. The key is that both of these comics explore the subtlety that what is good versus bad isn't cut and dried. Most people aren't really willing to spend their two hours of escape dealing with these subjects and want to see the bad guy lose because it represents their boss or ex or some other negative character in their lives.
Contrast Watchmen and Sin City with LOTR: ROTK where the ending was again turned into a much happier event than what was in the books. Now look at which of these three movies I discussed made the most money. That's what the studio execs are most interested in. I just hope the genre doesn't completely go away because of straight money concerns. Sometimes producing art for its own sake is a worth cause.
According to the article: "However, phosphor powder is highly toxic and its price is expensive. As a result, Dr. Yen-Hsun Wu had the idea to discover a method that is less toxic to replace phosphor powder. This is a major motivation for him to engage in the research at the first place."
Is gold really cheaper than phosphor powder? Chemists care to chime in? Is it the powder part that increases the price?
The big question I have for all of these technologies is whether or not is is mass production worthy and reliable over a normal usage life.
That said, there is a particular order of ease of simulation: percussion (including piano), strings, brass and woodwinds. The latter two are notoriously difficult to emulate because they are so closely tied to non-discrete complex forms of movement of the mouth (articulation). For example, see this demo of one of the betters saxophone emulators - still something missing even to uneducated ears, but not too bad in a mix. Strings can also be difficult to emulate, but if apps from companies like Prominy are coming out, guitars and violins, this is getting scary.
There are a couple of serious implications of this. First and foremost is what the value of a live performance is with and without musicians, which the linked article addresses. The second is decreasing numbers of people willing to learn these instruments. For a lot of folks who compose for small-budget TV and movies and can't afford musicians, it's a great way to go. Nevertheless, it's the same cautionary tale as the decline in handwriting that coincided with the rise of computers with keyboards. You can't replace handwriting in a lot of circumstances.
MPEG TS is higher in container overhead than MP4. Vudu happens to use it in their service, but it's a cut down version and was used primarily because the set of targeted devices for playback used it(i.e. TVs and STBs). I'd never choose it if I was starting any kind of streaming media service or defining a standard. There are even plenty of tools from companies like Rhozet and Digital Rapids to be able to batch re-mux and re-encode any content from MPEG TS to MP4.
By the way, you're all over the map with your standards. ISDB-T and DVB-H are broadcast standards that encompass much more than the media container specification, like the modulation scheme and receiver-level RF tests. MPEG TS is a container format defined in MPEG-2 Part 1 and is completely agnostic to broadcast standards and that physical medium, even though it is used almost exclusively in that domain.
Huawei should have been subject to ITC embargoes years ago for their technical thievery from the Western network equipment makers. It isn't a surprise to me that this kind of backdoor would exist. People get everything they deserve for buying their equipment from a company started by a Chinese army officer and Communist Party official.
I mostly agree with you: ownership should mean total control, so I should have total freedom to do whatever I want with my physical property.
The part where I disagree with you, I nevertheless actually agree in spirit: the DMCA is bullshit. It's bullshit because it prohibits too much. IIRC, it makes tinkering with devices illegal, and that's just ridiculous.
The part where I disagree with you is that I think reasonable copyright laws are good. What if I wrote some songs or something, someone else stole the music, and became rich and famous by claiming my stuff as their original? That's just plain wrong, so I think reasonable copyright has it's place.
Unfortunately, the DMCA is not reasonable copyright.
