### Ad Triumphalism, Education Not Transformed, Bookstore Infrastructure, and Tossable Camera

1. Why The Banner Ad is Heroic — enough to make Dave Eggers cry. Advertising triumphalism rampant.
2. Udacity/Thrun ProfileA student taking college algebra in person was 52% more likely to pass than one taking a Udacity class, making the $150 price tag–roughly one-third the normal in-state tuition–seem like something less than a bargain. In which Udacity pivots to hiring-sponsored workforce training and the new educational revolution looks remarkably like sponsored content. 3. Amazon is Building Substations (GigaOm) — the company even has firmware engineers whose job it is to rewrite the archaic code that normally runs on the switchgear designed to control the flow of power to electricity infrastructure. Pretty sure that wasn’t a line item in the pitch deck for “the first Internet bookstore”. 4. Panoramic Images — throw the camera in the air, get a 360×360 image from 36 2-megapixel lenses. Not sure that throwing was previously a recognised UI gesture. Comments: 3 | ## Four short links: 18 November 2013 ### Chicago Code, 3D Smithsonian Data, AI Controlling Everything, and Game TCP 1. The Virtuous Pipeline of Code (Public Resource) — Chicago partnering with Public Resource to open its legal codes for good. “This is great! What can we do to help?” Bravo Chicago, and everyone else—take note! 2. Smithsonian’s 3D Data — models of 21 objects, from a gunboat to the Wright Brothers’ plane, to a wooly mammoth skeleton, to Lincoln’s life masks. I wasn’t able to find a rights statement on the site which explicitly governed the 3D models. (via Smithsonian Magazine) 3. Anki’s Robot Cars (Xconomy) — The common characteristics of these future products, in Sofman’s mind: “Relatively simple and elegant hardware; incredibly complicated software; and Web and wireless connectivity to be able to continually expand the experience over time.” (via Slashdot) 4. An Empirical Evaluation of TCP Performance in Online GamesWe show that because TCP was originally designed for unidirectional and network-limited bulk data transfers, it cannot adapt well to MMORPG traffic. In particular, the window-based congestion control and the fast retransmit algorithm for loss recovery are ineffective. Furthermore, TCP is overkill, as not every game packet needs to be transmitted in a reliably and orderly manner. We also show that the degraded network performance did impact users’ willingness to continue a game. Comment | ## Sharing is a competitive advantage ### Why the Velocity conference is coming to New York. In October, we’re bringing our Velocity conference to New York for the first time. Let’s face it, a company expanding its conference to other locations isn’t anything that unique. And given the thriving startup scene in New York, there’s no real surprise we’d like to have a presence there, either. In that sense, we’ll be doing what we’ve… Read Full Post | Comment: 1 | ## The web performance I want ### Cruftifying web pages is not what Velocity is about. There’s been a lot said and written about web performance since the Velocity conference. And steps both forward and back — is the web getting faster? Are developers using increased performance to add more useless gunk to their pages, taking back performance gains almost as quickly as they’re achieved? I don’t want to leap into that argument; Read Full Post | Comments: 4 | ## Four short links: 6 August 2013 ### Modern Security Ethics, Punk'd Chinese Cyberwarriors, Web Tracing, and Lightweight Server OS 1. White Hat’s Dilemma (Google Docs) — amazeballs preso with lots of tough ethical questions for people in the computer field. 2. Chinese Hacking Team Caught Taking Over Decoy Water Plant (MIT Tech Review) — Wilhoit went on to show evidence that other hacking groups besides APT1 intentionally seek out and compromise water plant systems. Between March and June this year, 12 honeypots deployed across eight different countries attracted 74 intentional attacks, 10 of which were sophisticated enough to wrest complete control of the dummy control system. 3. Web Tracing FrameworkRich tools for instrumenting, analyzing, and visualizing web apps. 4. CoreOSLinux kernel + systemd. That’s about it. CoreOS has just enough bits to run containers, but does not ship a package manager itself. In fact, the root partition is completely read-only, to guarantee consistency and make updates reliable. Docker-compatible. Comment | ## Four short links: 14 February 2013 ### Malware Industrial Complex, Indies Needed, TV Analytics, and HTTP Benchmarking 1. Welcome to the Malware-Industrial Complex (MIT) — brilliant phrase, sound analysis. 2. Stupid Stupid xBoxThe hardcore/soft-tv transition and any lead they feel they have is simply not defensible by licensing other industries’ generic video or music content because those industries will gladly sell and license the same content to all other players. A single custom studio of 150 employees also can not generate enough content to defensibly satisfy 76M+ customers. Only with quality primary software content from thousands of independent developers can you defend the brand and the product. Only by making the user experience simple, quick, and seamless can you defend the brand and the product. Never seen a better put statement of why an ecosystem of indies is essential. 3. Data Feedback Loops for TV (Salon) — Netflix’s data indicated that the same subscribers who loved the original BBC production also gobbled down movies starring Kevin Spacey or directed by David Fincher. Therefore, concluded Netflix executives, a remake of the BBC drama with Spacey and Fincher attached was a no-brainer, to the point that the company committed$100 million for two 13-episode seasons.
4. wrka modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design with scalable event notification systems such as epoll and kqueue.

### Tweet Cred, C64 History, Performance Articles, Return of Manufacturing

1. Credibility Ranking of Tweets During High Impact Events (PDF) — interesting research. Situational awareness information is information that leads to gain in the knowledge or update about details of the event, like the location, people aff ected, causes, etc. We found that on average, 30% content about an event, provides situational awareness information about the event, while 14% was spam. (via BoingBoing)
2. The Commodore 64 — interesting that Chuck Peddle (who designed the 6502) and Bob Yannes (who designed the SID chip) are still alive. This article safely qualifies as Far More Than You Ever Thought You Wanted To Know About The C64 but it is fascinating. The BASIC housed in its ROM (“BASIC 2.0″) was painfully antiquated. It was actually the same BASIC that Tramiel had bought from Microsoft for the original PET back in 1977. Bill Gates, in a rare display of naivete, sold him the software outright for a flat fee of \$10,000, figuring Commodore would have to come back soon for another, better version. He obviously didn’t know Jack Tramiel very well. Ironically, Commodore did have on hand a better BASIC 4.0 they had used in some of the later PET models, but Tramiel nixed using it in the Commodore 64 because it would require a more expensive 16 K rather than 8 K of ROM chips to house.
3. The Performance Calendar — an article each day about speed. (via Steve Souders)
4. Mr China Comes to America (The Atlantic) — long piece on the return of manufacturing to America, featuring Foo camper Liam Casey.

### A/B with Google Analytics, Lego Rubiks Solver, TV Torrents, and Performance Tools

1. ABalytics — dead simple A/B testing with Google Analytics. (via Dan Mazzini)
2. Fastest Rubik Cube Solver is Made of Lego — it takes less than six seconds to solve the cube. Watch the video, it’s … wow. Also cool is watching it fail. (via Hacker News)
3. Fairfax Watches BitTorrent (TorrentFreak) — At a government broadband conference in Sydney, Fairfax’s head of video Ricky Sutton admitted that in a country with one of the highest percentage of BitTorrent users worldwide, his company determines what shows to buy based on the popularity of pirated videos online.
4. Web Performance Tools (Steve Souders) — compilation of popular web performance tools. Reminds me of nmap’s list of top security tools.

### Post-Capture Zoom, Load Gen, Inventive Malware, and Manufactured Normalcy

1. SnapItHD — camera captures full 360-degree panorama and users select and zoom regions afterward. (via Idealog)
2. Iago (GitHub) — Twitter’s load-generation tool.
3. AutoCAD Worm Stealing Blueprints — lovely, malware that targets inventions. The worm, known as ACAD/Medre.A, is spreading through infected AutoCAD templates and is sending tens of thousands of stolen documents to email addresses in China. This one has soured, but give the field time … anything that can be stolen digitally, will be. (via Slashdot)
4. Designing For and Against the Manufactured Normalcy Field (Greg Borenstein) — Tim said this was one of his favourite sessions at this year’s Foo Camp: breaking the artificial normality than we try to cast over new experiences so as to make them safe and comfortable.
