Frederick Schuller's Lectures on Geometrical Anatomy of Theoretical Physics, https://www.youtube.com/playlist?list=PLPH7f_7ZlzxTi6kS4vCmv.... A meticulously organized series covering the math concepts needed to understand the ideas of modern physics. Not for the faint of heart, but well worth the effort.
I really wanted to watch this, but the video is unwatchable, it keeps buffering every few seconds, and the slides aren't showing at all. Many thanks to pron for linking the paper. Message to http://www.heidelberg-laureate-forum.org/ and all others who persist in using video players that don't work: maybe try youtube?
First, thank you Matthew and HN for a great resource.
Re metadata, please don't "require" it. I agree it would be nice if posters could find a more search-friendly way of saying "no remote", but I think it would be a huge mistake to impose any sort of format or content requirements, or any other barriers that increase the hassle for posters. Even something innocuous like "please read these simple guidelines before posting", and I would predict the number of posts will go down significantly. Our goal as programmers should be to write filters that can handle free form data, within reason, not to force humans into rigid forms for the convenience of easy filtering. Please don't surrender yet another valuable tool to the HR everything-must-fit-in-its-box mindset.
The 'insider' complaining here is -- Oracle?? That would be the Oracle that is No. 58 in the PTO's list of the top 100 most prolific patenters? Who is the troll here?
Number of patents filed doesn't by itself mean anything. These days, companies have to amass large patent portfolios for defensive purposes, if nothing else. Failure to do so would get them sued by their shareholders.
The question is to what extent they use their patents aggressively, and how good a case they have when they do so. I don't know the answer in Oracle's case (and I'm no great fan of the company) but again, mere numbers of patents won't tell you that.
1. Having patents and enforcing them does not make you a troll. It's generally understood that trolls are non-practicing entities. Unfortunately, people frequently use the word as a derogatory term for "someone who uses patents in a way I don't like" (which often really means "someone who uses patents for their intended purpose, which I don't like on principle"), making it lack any real meaning.
2. That someone as litigious as Oracle was supporting this should tell you something: that this effort had little to do with "reforming patents" and more to do with "large corporations managing risk".
> Having patents and enforcing them does not make you a troll. It's generally understood that trolls are non-practicing entities.
Apple and Microsoft have managed to turn that line thoroughly into mud by weaponizing patent trolling as a tool to wage proxy wars.

Patent trolling as a practice has quite clear contours: The perpetrator alleges patent infringement and demands a license fee which is less than the cost of proving non-infringement or patent invalidity in court, leaving the victim having to either pay the troll the Danegeld regardless of infringement or pay even more to their own lawyers to prove otherwise.

Your explanation is belied by the number of patent nastygrams received by startups that can hardly be described as "large corporations." That we see Oracle on the side of reform next to the likes of Red Hat and the EFF only goes to the severity of the problem.
> Apple and Microsoft have managed to turn that line thoroughly into mud by weaponizing patent trolling as a tool to wage proxy wars.
1. Apple and MS have historically sued competitors with their own patents, which typically they practice themselves.
2. The only conceivable "proxy" may be Rockstar, and they claim to operate independently. If they didn't, well, the DOJ and FTC would be mighty interested [1].
>Patent trolling as a practice has quite clear contours:...
And my point was, Oracle clearly don't fit the bill. Heck, even IV don't fit that bill, because they apparently ask for pretty large licensing fees.
>Your explanation is belied by the number of patent nastygrams received by startups that can hardly be described as "large corporations."
Outside of cherrypicked media reports, there is insufficient empirical evidence that trolls target startups. I've been tracking trolls for a while, and trolls that go after the little guys are actually rare. The moment they do, there's inevitably some media outrage, and the number of unique trolls so far have been few (lodsys, scanner trolls, WiFi trolls... Fotomedia / photo sharing trolls about 7 years back... Any more?) By and large these pick on larger companies, because that's where the big money is.
> 1. Apple and MS have historically sued competitors with their own patents, which typically they practice themselves.
So you can't be a patent troll if you weren't one three years ago?
> 2. The only conceivable "proxy" may be Rockstar, and they claim to operate independently. If they didn't, well, the DOJ and FTC would be mighty interested [1].
In much the same way as a toy soldier can "claim to operate independently" after you release it having wound it up and pointed it in the direction you want it to go.
> Heck, even IV don't fit that bill, because they apparently ask for pretty large licensing fees.
Compared to cost of trial and appeals + impact on customer opinion of company + impact on shareholder confidence + risk of pro-plaintiff East Texas court or pro-plaintiff Federal Circuit judges reaching an incorrect decision and product being taken off the market during further appeals? What are they asking, hundred million dollars + first born child?
> Outside of cherrypicked media reports, there is insufficient empirical evidence that trolls target startups.
Of course there isn't. For a startup fighting is equivalent to bankruptcy and the settlement comes with an NDA. Suppressing all the evidence you can and then claiming there isn't sufficient evidence is not a very strong argument.
> So you can't be a patent troll if you weren't one three years ago?
Not sure where you got that. I meant if you don't exist for the sole purpose of asserting a patent, you can't be a troll.
> In much the same way as a toy soldier can "claim to operate independently" after you release it having wound it up and pointed it in the direction you want it to go.
1. Actually, Nortel was already hitting firms up for licensing those patents before they went down. It was already "wound up and pointed in the right direction." Everyone knew what was coming. The companies that bought them did so to manage their own risk. They are now simply going after the rest of the industry that failed to do so.
2. Rockstar is now suing giant corporations like Google and Samsung. You think they wouldn't get the FTC and DoJ involved if they could prove anything?
>Compared to cost of trial and appeals ...
Those are the only concrete costs. Everything else is handwavy (public opinion? Really? Impact on stock? The weather has more impact) or highly unlikely (injunctions). The companies IV goes after can certainly afford to take them on.
> pro-plaintiff Federal Circuit judges
I'd encourage you to lay off Timothy Lee's articles about the Federal Circuit and actually look up statistics about their decisions.
> Of course there isn't. For a startup fighting is equivalent to bankruptcy and the settlement comes with an NDA.
1. Absence of evidence is not evidence of absence, but it's not proof that evidence is being suppressed either. claiming something is a problem without sufficient evidence is not a very strong evidence either.
2. Evidence always leaks out. All those other trolls no doubt have NDAs, yet we hear of them. If so many startups are getting hit, where were the VCs in this whole thing?
Nonetheless, there's something in the works about making these "nastygrams" more trackable. That will give us enough data to see how much of a problem this really is. Until then all we have is a outrage driven by a media hungry for rageviews and informed by PR.
> Apple and Microsoft have managed to turn that line thoroughly into mud by weaponizing patent trolling as a tool to wage proxy wars.
Which is why I favor calling them patent ogres, not patent trolls. What Apple and Microsoft (most notably among others) are doing is different, but similarly troubling.
