on: Show HN: Mediachain Attribution Engine
Because our system represents extant authorship relationships (as opposed to creating a whole new first-to-file system like some other approaches in the space), we defer to existing authorities whenever possible -- so authorship information provided by MoMA, NYPL, DPLA, etc is considered authoritative, whereas statements by a private individual generally do not carry the same weight. All of this (including conflicting statements) is surfaced at read time and can be subject to different weighting depending on the situation (best-effort attempt to find the author of an image for discovery purposes, versus automatic payment, for example)

Absolutely! Spotify's 30M settlement with NMPA is a great example of this kind of failure in existing systems

Declaring ownership and provenance with complete certainty is very hard, which is why we don't profess to do it. Our approach is to nondestructively aggregate potentially conflicting claims and allow for more nuanced resolution at read time, as appropriate for a given situation. In your particular example, we would have a chain of derivative works.
Obviously, in certain cases (payment routing) a definitive answer is required, but this is already something that PROs and similar organizations deal with on a daily basis, and we can support their arbitration.

Filecoin is one of several proposed approaches for encouraging seeding ("pinning") in the IPFS network. In our network (Mediachain), we will probably start out by using tit-for-tat pinning between peers for this purpose.

on: Microsoft Introduces New "Surface" Tablet
Actually, you could program for the eMate (NewtonScript, which is surprisingly powerful -- you do need a mac to build the app but you could write code on the device itself, there were apps for this), and you could connect to the internet, too -- I had a PCMCIA ethernet card with a pop-out jack in mine. I fondly remember printing to a HP laser printer via the IR port in the library, bypassing normal printing limits.

To paraphrase the well-known maxim, you can never go broke underestimating the good taste of the american public (over a long enough timeframe). The IP status of the voice is a really fascinating question though, given how complex the current songwriting/master/recording breakdown is already.

I can't wait for real animated holography to become available commercially. The static prints that Zebra Imaging makes are already incredible (full color, 90 degree viewing angle, etc) and the video footage of their live table prototype looks nuts, though it needs on the order of 100GBps of hogel data coming into the surface for 3x3ft image...

Rebuilding speech/song based on existing phoneme library (i.e. the discography) is already practical and, like everything else in this domain, has been done long ago in japan:

on: An Open Letter to JavaScript Leaders Regarding Semicolons
Be very, very careful when you're using PHP as an example of the proper way to do something, because you're probably at least partially wrong. Semicolons are optional when followed by a closing tag (and likewise, closing tags are optional when the last statement ends with a semicolon -- in this case, whitespace at the end of the file is valid, as well)

on: Inside Apple's Actual Distortion Field
Am I wrong in thinking that this is a completely industry-standard setup for RF testing? Many of the passages make it seem that Apple is going above and beyond the call of duty in their testing (like the heads filled with solution approximating tissue), but it seems to me like these are essentially minimal due-diligence procedure mandated by the FTC. Hell, I'm pretty sure some of the (severely underfunded) labs back at my university had similar equipment.
Can anyone more familiar with the industry comment on what sort of facilities other vendors use?

These are just a few statements I picked at random, without even taking the bait of spurious, unsupported "rah rah free markets would have made it better!" fluff sprinkled throughout. I don't know how you can celebrate innovation and be so thoroughly wrong on so many facts in a single article.

This article appears highly questionable (as Reason fodder often is). The list of "20th-century inventions that were never patented" is completely wrong, cellophane is USPTO #1266766, Bakelite is #1233298, zippers are contested because of terminology and structure differences but there's at least two candidates, and the others are probably covered by dozens if not hundreds separate patents. Not that I think the modern intellectual property system is functional or sane, of course.
The structure and basic mechanism of action of penicillin was determined in 1945, not that much later than its 1928(ish) discovery and certainly not "the time bacteria learned to defeat it".
I don't even know what to make of the comment that machines in early industrial england "would not have surprised Archimedes".
The sole source to support the claim about nonexistent connections between science spending and innovation appears to be an OECD study, which I would very much like to see.
Hero of Alexandria worked (as the name suggests) in a hub of technological development, published extensively, and was cited by many influential arabic texts.
Dude, come on.

on: Ask HN: Please explain short selling?
fexl, loom looks very interesting, and the maintainer (you?) actually touches up on some specific market-based ideas I've been sort of idly kicking around in the FAQ (e.g. phone service contract exchanges). Is there a way to get an invite/sponsorship to play around with the system?
