Google Chrome now uses SPDY HTTP replacement, halves page load time

SPDY in Google Chrome
We're not entirely sure of the time line here, but it looks like Google has now rolled out the SPDY HTTP replacement to its full bevy of Web services, including Gmail, Docs, and YouTube. If you're currently using Google's Chrome browser you're probably already using SPDY.

We originally reported on SPDY way back in November 2009, when Google introduced it as yet another experiment in making the Web faster, like Go, Native Client and speculative pre-connections. Over the last 18 months, though, SPDY support has found its way into the stable build of Chrome.

SPDY is basically a streamlined and more efficient version of HTTP. At its most basic, SPDY introduces parallel, multiplexed streams over a single TCP connection -- but at the same time, SPDY allows for prioritization, so that vital content (HTML) can be sent before periphery content (JavaScript, video). All in all, the SPDY protocol can halve page load times, which is obviously rather significant.

The best bit, though, is that SPDY is an open-source project. HTTP 1.1 is a lumbering beast that needs to be replaced before low-latency real-time computing really becomes a reality, and SPDY is one of the best options currently on the table. To be honest, we're not sure why SPDY hasn't received more coverage -- it's awesome in every way. At the moment, though, the only way to help speed up SPDY's proliferation, is with an experimental Apache mod.

As far as actually 'trying it out,' your best bet is downloading Chrome, hitting up some Google sites, and then checking chrome://net-internals to see your active SPDY sessions. SPDY is a transparent replacement for HTTP, though, and as such it's rather hard to see its effects. Google's sites definitely feel fast in Chrome, but there are more technologies than just SPDY at work.

How to easily transcribe audio or video recordings into text

I recently had to transcribe a number of video interviews into text. This turned out to be much more of a labor intensive project than I thought, and it quickly dawned on me that the process can be vastly improved via a few technological tweaks. This posting aims to present a step by step ...

Why won't Intellectual Ventures answer questions about its relationship with Lodsys?

Is ex-Microsoftie Nathan Myrhvold's company getting shell companies like Lodsys to demand payment for software patents? And is there any evidence those patents help innovation in software?

When it comes to software patents, one company has recently become more and more noticeable for its position defending them: Intellectual Ventures, a company run by Nathan Myhrvold, who founded it in 2000 after leaving Microsoft, where he was chief technology officer.

It's a company which has received $300m of funding from venture capitalists Charles River since 2006: "Nathan helped open my eyes to the notion that IP [intellectual property] is a very important market ? it's actually a very big market in tech," Izhar Armony, a partner at Charles River Ventures, says in the linked interview from April. He thinks there's a $6bn litigation market based on legal fees, and a $50bn market in IP rights and licensing.

Here's the odd thing: Intellectual Ventures doesn't seem to be very good at exploiting patents it owns. In two cases it appears to have bought software patents that have value in the courts and then transferred them to little one-man bands who have abruptly realised their value and begun suing people for infringing them.

The two companies: Oasis Research and Lodsys. You may have heard of the latter: it is suing a number of app developers on the Android and Apple iOS platforms, claiming that they infringe patents that it owns, particularly covering in-app purchases. Despite attempts by Apple to intervene ? because it says that it has licensed those patents ? the cases seem to be going ahead. And its determination to prevail has, as we've written, led to some European app developers deciding that the US game isn't worth the candle.

In other words, software patents are doing the same to the US's standing as a centre for innovation and competition as the debt ceiling issue is doing to its financial standing: destroying it hour by hour. (The NPR program This American Life had an hour-long episode about "invention peddlers" which looks at this in detail.)

You don't have to look far to find venture capitalists who decry what Myhrvold represents. Paul Kedrosky wrote on 19 July that Myhrvold's arguments "veer from hysterical, to unsupportable, and back again", pointing to a Myhrvold column at Bloomberg.

One key sentence from Kedrosky's denunciation: "There is no inconsistency in promoting innovation while attacking the software patent system. Most software companies, large and small, think the patent system is an obstacle to innovation given the prevalence of nonsensical blocking patents and patent trolls. I would hope that they attack it ... This is far, far from a disinterested observer of a fundamentally broken US software patent system. Let's end the deference."

Fred Wilson, principal of Union Square Ventures, who has backed a number of companies, including Twitter, said as long ago as 2009 that patent trolls are a tax on innovation, after one of his funded companies spent $500,000 defending itself against baseless patent claims.

But Intellectual Ventures stands ? apparently ? aloof from all this. It isn't, as far as I know, involved in any lawsuits where it is asserting any of the patents that it owns. For a company that has $300m of venture capital funding, that seems odd ? as does the seeming lack of nous about the value of the patents that it held but then transferred (it's not clear whether "sold" is the right phrase here) to those companies.

There's more, though. A research firm last year released a report claiming that Intellectual Ventures has as many as 1,100 shell companies which it uses to carry out patent "shakedowns": the front companies do the suing, and the parent reaps the benefits.

I contacted Intellectual Ventures on Tuesday evening, and spoke to a person to put a number of detail questions about its relationship with Oasis Research and Lodsys.

Here are the questions that I subsequently put via email (in time for them to be answered during the Seattle business day):

? Does Intellectual Ventures have any royalty or licensing agreement with Lodsys over the patents that it transferred to it? And when did it sell/transfer them?

? What form did the transfer of patents to Lodsys take: simple sale and complete title, or some other arrangement?

? Does Intellectual Ventures have any royalty or licensing agreement with Oasis Research over the patents that Intellectual Ventures transferred to it? And when did it sell/transfer them?

? What form did the transfer of patents to Oasis Research take?

? Has Intellectual Ventures made any investment in Lodsys?

? Are any of the staff or owners of Lodsys present or former staff or owners of Intellectual Ventures?

? Why would Intellectual Ventures, a considerably funded company with large resources, sell patents with clear value to apparently low-funded companies ? Lodsys and Oasis Research?

? Is Intellectual Ventures providing any funding or legal assistance for the legal actions being pursued by Lodsys and/or Oasis Research?

These seem fairly narrow questions ? that is, they aren't asking for a long thoughtful post on the nature of patents. They're factual.

On Wednesday morning, five hours after I sent those questions, I received a response from Intellectual Ventures. It pointed to a blog post that the company had put up overnight ? which is dealt with below ? and had this response to my questions:

"Specific to your questions on divesting patents, as has been reported, when it makes sense for our business we sell patents ? either to companies who can use them for defensive purposes or to buyers who monetise them. Sometimes based on the structure of the sale we have a financial interest in the outcome of those efforts, but we never have control over, or are involved in, the path to monetisation that these companies pursue once we sell the patent."

Note that this doesn't answer a single one of the specific questions about IV's involvement with Oasis Research or Lodsys (particularly about staff, investment, legal fees or form of transfer). It doesn't say whether it was a sale or other form of transfer ? though it does talk about "structure" which could mean payback. It doesn't mention involvement. Simply, it's a non-answer. I've emailed back reiterating the specifics of the questions and asking for detailed responses.

Meanwhile, there is the blogpost which appeared on IV's site. This says, in part:

"By definition, a disruptive innovation is a product or technology that, when introduced, either radically changes existing markets or creates wholly new ones, thereby disrupting companies and networks reliant on the status quo. In simpler terms, it signifies rapid and unexpected progress ? a change in context. Intellectual Ventures is a disruptive organisation, and like any other product or service which disrupts established markets, we've invited our share of controversy... We appreciate that patents are an emotionally charged issue that generates a lot of conversation and varying points of view, but we want to take a moment to provide our perspective on a recent characterisation.

"IV believes that inventors who invest all the time, money, and emotional resources that are required to protect their ideas with patents earn a right to recognise a return on their investments.

"IV is challenging the status quo by focusing its business solely on invention and investment in patents. But we think this disruption is an important and necessary step in the development of a fully functioning marketplace for ideas. Our ultimate value proposition is simple: we provide an efficient way for patent holders to get paid for the inventions they own, and in turn, for technology companies to gain easy access to the invention rights they need now or may need as they enter new markets."

None of this however answers the wider question: is the exercise of these patents actually stimulating innovation? Is it to the benefit of real inventors, if the patents are traded on? (The original inventor who was awarded the patents now owned by Lodsys is bemused by the attention paid to them. He has also had to suffer a fair deal of unwarranted abuse, since he's nothing to do with IV or Lodsys.)

We've seen nothing from Myhrvold indicating how it might. There is his quote in an interview with Forbes that "we want to build a portfolio just like those companies have, with licensing approaches broadly like they have ... I want to achieve what IBM has achieved [getting $1bn per year from licensing patents]. That's my financial model. This is a play where I take portfolio theory and apply it to something illiquid to deliver a return for my investors. I don't see that as evil. I don't see that as particularly threatening."

The unanswered question remains, though: do software patents really spur innovation, or hold it back?

BitTorrent users don't "act in concert," so judge slashes mass P2P case

Steele Hansmeier, the antipiracy law firm that has been routinely hammered by judges in Illinois, is now getting hammered by judges in California. The firm has tried desperately to head off all the common objections to its mass file-sharing lawsuits over online porn, and has even taken to geolocating IP addresses before filing a lawsuit; its Hard Drive Productions case in California only went after 188 IP addresses that appeared to be located in the state. But the firm still had its entire case severed down to a single defendant last week.

Geolocation tools may help convince skeptical judges that a lawsuit is more than a national fishing expedition, one mainly targeting people outside a court's personal jurisdiction. (Judges in other jurisdictions have expressed annoyance such tools weren't first used to winnow the list of IP addresses.) But P2P lawsuits have other problems, including the fact that they generally "join" people who have little in common except for a taste in digital porn (in this case "Amateur Allure - Erin"). And increasingly savvy judges are now parsing claims about BitTorrent with a scholar's eye to see if these defendants really should be linked.

Mid-2011 MacBook Air reportedly about to launch in China

Fortune's Apple 2.0 is reporting that the mid-2011 MacBook Air (launched just over a month ago in the US) is set to launch in China in the next week or so. According to analyst Brian White of Ticonderoga Securities, this week's Hong Kong launch of the MacBook Air was met with, "long lines and stock outs of certain new MacBook Air models," which is an indication of what's to come when the MacBook Air launches in Greater China.

White says, "Our field checks indicate that several Apple authorized resellers in Beijing, Shanghai and Shenzhen are experiencing stock outs of the previous version of MacBook Air, which we believe is in preparation for the launch of the new MacBook Air." White goes on to say that the MacBook Air could launch "as early as next week at some stores."

Either way, with iPhone and Mac sales booming in Asia, fake Apple Stores and fake Steve Jobs biographies cropping up aplenty in China, and the ever increasing rumors surrounding the iPhone hitting China Telecom, it's clear China is going to be a large market for Apple in the future.
