Pseudo Memetics, Top Pinch or Bottom Pinch, Innovation Cartography, and Awesome Compilation Hackery
- Anatomy of Two Memes — comparing the spread of Gangnam Style to Harlem Shake. Memes are like currencies: you need to balance accessibility (or ‘money supply’) and inflation. Gangnam Style became globally accessible through top-down mainstream sources (High Popularity), but this gave it high social inflation so it wasn’t valuable to share (Low Shareability). However, scale sustained its long term growth. Harlem Shake was not as easily accessible because it was driven more by small communities (Low Popularity), but for the same reason, being less easily accessible, it remained highly valuable (High Shareability). Lack of scale was what made Harlem Shake growth short-term and eventually killed it prematurely. Caution: contains fauxconomics.
- Handedness (Github) — determine left or right handedness from pinch gesture.
- Innovation Cartography — video of a talk by Richard Jefferson of Cambia’s lens, on the imperative to innovate held at the Skoll World Forum on Social Enterprise. His story of maritime cartography (starts around 5m50s) is awesome.
- Statically Recompiling NES Games into Native Executables with LLVM and Go — or “crack for Nat” as I like to translate that title.
China Threat, China Opportunity, Open Source Sustainability, and SQL for Cohort Analysis
- China = 41% of World’s Internet Attack Traffic (Bloomberg) — numbers are from Akamai’s research. Verizon Communications said in a separate report that China accounted for 96 percent of all global espionage cases it investigated. One interpretation is that China is a rogue Internet state, but another is that we need to harden up our systems. (via ZD Net)
- Open Source Cannot Live on Donations Alone — excellent summary of some of the sustainability questions facing open source projects.
- China Startups: The Gold Rush (Steve Blank) — dense fact- and insight-filled piece. Not only is the Chinese ecosystem completely different but also the consumer demographics and user expectations are equally unique. 70% of Chinese Internet users are under 30. Instead of email, they’ve grown up with QQ instant messages. They’re used to using the web and increasingly the mobile web for everything, commerce, communication, games, etc. (They also probably haven’t seen a phone that isn’t mobile.) By the end of 2012, there were 85 million iOS and 160 million Android devices in China. And they were increasing at an aggregate 33 million IOS and Android activations per month.

Engagement Cliff, SSL Best Practices, Public Domain Numbers, and GitHub License Sniffing
- The Engagement Cliff — Gallup surveyed nearly 500,000 students in grades five through 12 from more than 1,700 public schools in 37 states in 2012 and found that by the time students get to high school only about 4 in 10 qualify as engaged.
- SSL/TLS Deployment Best Practices — clear and concise instructions to help overworked administrators and programmers spend the minimum time possible to obtain a secure site or web application. In pursue of clarity, we sacrifice completeness, foregoing certain advanced topics. The focus is on advice that is practical and easy to understand.
- Do Bad Things Happen When Works Enter The Public Domain? — research to answer that question. Spoiler: no. (via Surprisingly Free)
- Most GitHub Projects Not Open-Source Licensed (The Register) — 1,692,135 code repositories scanned, 219,326 (14.9%) percent had a file in their top-level directories that identified any kind of license at all. Of those, 28 per cent only announced their licenses in a README file, as opposed to recommended filenames such as LICENSE or COPYING. MIT license overwhelmingly popular compared to the different reciprocal (GPL-like) ones.
Solar Numbers, Process Managers, BitTorrent Sync, and Motherfrickin' Snakes in Your Motherfrickin' Browser
- Solar Energy: This is What a Disruptive Technology Looks Like (Brian McConnell) — In 1977, solar cells cost upwards of $70 per Watt of capacity. In 2013, that cost has dropped to $0.74 per Watt, a 100:1 improvement (source: The Economist). On average, solar power improves 14% per year in terms of energy production per dollar invested.

Chinese Lessons, White House Embraces Makers, DC Codes Freed, and Malware Numbers
- What American Startups Can Learn From the Cutthroat Chinese Software Industry — It follows that the idea of “viral” or “organic” growth doesn’t exist in China. “User acquisition is all about media buys. Platform-to-platform in China is war, and it is fought viciously and bitterly. If you have a Gmail account and send an email to, for example, NetEase163.com, which is the local web dominant player, it will most likely go to spam or junk folders regardless of your settings. Just to get an email to go through to your inbox, the company sending the email needs to have a special partnership.” This entire article is a horror show.
- White House Hangout Maker Movement (Whitehouse) — During the Hangout, Tom Kalil will discuss the elements of an “all hands on deck” effort to promote Making, with participants including: Dale Dougherty, Founder and Publisher of MAKE; Tara Tiger Brown, Los Angeles Makerspace; Super Awesome Sylvia, Super Awesome Maker Show; Saul Griffith, Co-Founder, Otherlab; Venkatesh Prasad, Ford.
- Municipal Codes of DC Freed (BoingBoing) — more good work by Carl Malamud. He’s specifically providing data for apps.
- The Modern Malware Review (PDF) — 90% of fully undetected malware was delivered via web-browsing; It took antivirus vendors 4 times as long to detect malware from web-based applications as opposed to email (20 days for web, 5 days for email); FTP was observed to be exceptionally high-risk.
Courier Prime, Lethal Education, Internet Numbers, Mobile Numbers
- Courier Prime — tweaked Courier “for screenplays” (!). (via BoingBoing)
- The Dead Grandmother/Exam Syndrome and the Potential Downfall Of American Society (PDF) — education is dangerous to female extended family members. As can be seen in Table 1, when no exam is imminent the family death rate per 100 students (FDR) is low and is not related to the student’s grade in the class. The effect of an upcoming exam is unambiguous. The mean FDR jumps from 0.054 with no exam, to 0.574 with a mid-term, and to 1.042 with a final, representing increases of 10 fold and 19 fold respectively. (via Hacker News)
- Internet: 2012 in Numbers — lots of surprising numbers, with sources. Three that caught my eye: 42.1% – Internet penetration in China; 2.7 billion – Number of likes on Facebook every day; 59% – Share of global mobile data traffic that was video.
- 2013: The Year Ahead in Mobile (Business Insider) — Mobile is already 1/7 of global Internet traffic and growing its share quickly [...] on pace to top 25% by year end. Interesting prediction that rich people already have devices, so everyone’s working on low-cost units so they can sell to new customers in “growth markets” aka developing world.
Vanishing Landlines, Factory Help, Spectral Analyzer, and the State of the World
- Wireless Substitution (BoingBoing, CDC) — very nice graph showing the decline in landlines/growth in wireless.
- Maker’s Row — Our mission is to make the manufacturing process simple to understand and easy to access. From large corporations to first time designers, we are providing unparalleled access to industry-specific factories and suppliers across the United States.
- mySight (GitHub) — myspectral.com Spectruino analyzer for light spectra in UV/VIS/NIR.
- State of the World (Bruce Sterling, John Lebkowsky) — always a delight. Come 2013, I think it’s time for people in and around the “music industry” to stop blaming themselves, and thinking their situation is somehow special. Whatever happens to musicians will eventually happen to everybody. Nobody was or is really much better at “digital transition” than musicians were and are. If you’re superb at digitalization, that’s no great solution either. You just have to auto-disrupt and re-invent yourself over and over and over again.
