ENTRIES TAGGED "numbers"
- Google Keyword Advertising — interesting infographic about the most lucrative advertising categories for Google. #20 is an eye-opener!
- Etsy AB (GitHub) — Etsy’s framework for A/B testing, feature ramp up, and more. (via Randy J. Hunt)
DIY Bio Hardware, App Store Numbers, Open Hardware Repository, and Science Startups
- OpenPCR Shipping — A PCR machine is basically a copy machine for DNA. It is essential for most work with DNA, things like exposing fraud at a sushi restaurant, diagnosing diseases including HIV and H1N1, or exploring your own genome. The guy who discovered the PCR process earned a Nobel Prize in 1993, and OpenPCR is now the first open source PCR machine. The price of a traditional PCR machine is around $3,000. This one is $512 and would go well with Ben Krasnow’s Scanning Electron Microscope. Biological tools get closer to hobbyist/hacker prices. (via Gabriella Coleman)
- Apple App Store Figures (Fast Company) — 1 billion apps in a month, 200M iOS users, $2.5B revshare to developers so far (implying a further $5.8B revenue kept by Apple). Another reminder of the astonishing money to be made by riding the mainstreaming of tech: as we move from dumb phones to smart phones, the market for Apple’s products and App Store sales will continue to rise. We’re not at the fighting-for-market-share stage yet, it’s still in the boom. (via Stephen Walli)
- Open Hardware Repository — open source digital hardware projects, such as a tool for generating VHDL/Verilog cores which implement Wishbone bus slaves with certain registers, memory blocks, FIFOs and interrupts. CERN just approved an open license for hardware designs. (via CERN)
- Wingu — SaaS startup to help scientists manage, analyze, and share data. Recently invested by Google, it’s one of several startups for scientists, such as Macmillan’s Digital Science which is run by Timo Hannay who is one of the convenors of Science Foo Camp. (via Alex Butler)
Mediasaurus Dix, Mobile Numbers, Machine Learning, and Software Patents
- Networks Blocking Google TV — the networks are carrying over their old distribution models: someone aggregates eyeballs and pays them for access. In their world view, Google TV is just another cable company. They’re doubling down on this wholesale model, pulling out of Hulu and generally avoiding dealing with the people who ultimately watch their shows except through ad-filled shows on their corporate sites. (via Gina Trapani)
- Mobile Market Snippets — lots of numbers collected by Luke Wroblewski. After the Verizon iPhone launched in the U.S., Android suffered its first quarterly decline. Apple’s share of the U.S. smartphone market gained 12.3% to 29.5% in the March quarter while Android’s share in the U.S. fell from 52.4% to 49.5% — its first sequential loss in any region of the world since early 2009. The post has lots more like that.
- Unsupervised Feature Learning and Deep Learning Tutorial — This tutorial will teach you the main ideas of Unsupervised Feature Learning and Deep Learning. By working through it, you will also get to implement several feature learning/deep learning algorithms, get to see them work for yourself, and learn how to apply/adapt these ideas to new problems.
- A Generation of Software Patents — This report examines changes in the patenting behavior of the software industry since the 1990s. It finds that most software firms still do not patent, most software patents are obtained by a few large firms in the software industry or in other industries, and the risk of litigation from software patents continues to increase dramatically. Given these findings, it is hard to conclude that software patents have provided a net social benefit in the software industry.
Fair Use, Equation UI, Startup Numbers, and Data Search Engine
- Putting Fair Use Forward (Chronicle of Higher Education) — lawyer and academic collaborating on guidelines for academic fair use, intended to remove the chilling effect of the fear of being sued. Great quotes: People deal with fuzzy laws all the time, she argues. “Obscenity is impossible to define, and yet people have some idea of when they’re committing an obscenity or not. You could walk through your life being haunted by the specter of litigation in every aspect of it. But people don’t usually do this in their other free-speech rights.” (via David Adler)
- Scrubbing Calculator — clever UI for solving equations without needing to know how to solve equations. Imminent death of mathematics skill in the US predicted, film at 11. (via Dan Meyer)
- Startup Genome — a report, written from research into 650 startups. Investors who provide hands-on help have little or no effect on the company’s operational performance. But the right mentors significantly influence a company’s performance and ability to raise money. (However, this does not mean that investors don’t have a significant effect on valuations and M&A) Balanced teams with one technical founder and one business founder raise 30% more money, have 2.9x more user growth and are 19% less likely to scale prematurely than technical or business-heavy founding teams.
- Zanran — search engine for graphs, charts, and data. (via Pia Waugh)
Healthcare Data, C64 Emulator, Python Machine Learning, and Startup Success Stats
- E-Referral Evaluation Interim Findings — in general good, but note this: The outstanding system issues are an ongoing source of frustration and concern, including [...] automated data uptake from the GP [General Practitioner=family doctor] PMS [Patient Management System], that sometimes has clearly inaccurate or contradictory information. When you connect systems, you realize the limitations of the data in them.
- c64iphone (GitHub) — the source to an iPhone/iPad app from the store, released under GPLv3. It incorporates the Frodo emulator. Sweet Freedom.
- mlpy — machine learning Python library, a high-performance Python package for predictive modeling. It makes extensive use of NumPy to provide fast N-dimensional array manipulation and easy integration of C code. (via Joshua Schachter)
- What is The Truth Behind 9 Out of 10 Startups Fail? (Quora) — some very interesting pointers and statistics, such as Hall and Woodward (2007) analyze a dataset of all VC-backed firms and show the highly skewed distribution of outcomes. VC revenue averages $5 million per VC-backed company. Founding team averages $9 million per VC-backed company (most from small probability of great success). The economically rational founding team would sell at time of VC funding for $900,000 to avoid the undiversified risk. (via Hacker News)
Twitter Numbers, Online News, Emotional Complexity, and Making Described
- Twitter Numbers — growing at half a million accounts a day (how many are spammers, d’ya think?), over 140M tweets sent each day.
- Online vs Newspaper News (Mashable) — The Poynter Institute, a landmark of American journalism research, has determined that as of the end of 2010, more people get their news from the Internet than from newspapers — and more ad dollars went to online outlets than to newspapers, too. (via Sacha Judd)
- Blue Lacuna: Lessons Learned Writing the World’s Longest Interactive Fiction (PDF) — While I felt Progue was largely a success, the extreme complexity of the character’s code made difficulties with him both intensely difficult to diagnose and repair, and failures all the more mimesis-breaking for an engaged audience. In addition, the subtle text substitutions and altered behaviors provided in many cases too opaque a window into Progue’s interior workings. From informal interviews and published reviews I gathered that players could often not tell which conversation responses might cause Progue to become more submissive, paternal, and so on. In many cases, the change was not noticeable at all, and did not successfully indicate to players that their actions had had an eect on the character. More mechanisms to let the player shape their relationship with Progue more directly might have created a stronger feeling of agency for players, and an increased ability to shape the story more to their liking. Lessons for people designing complex emotional states into their products. (via Zack Urlocker)
- From Head to Hand (Slate) — I was searching for the place where someone, anyone, writes about that epiphany where you see what you have made and it is different from what you had conceived. I was searching for a description of how an object can displace a bit of the world. I was avid. I wanted someone to write a description of Homo faber, the maker of things. I wanted a story of making told without the penumbra of romanticising how hard it is, without nostalgia.
Facebook Bank, New in NoSQL, Twitter Numbers, and Open Source EEG Driver
- ASB Bank’s Facebook Virtual Branch — the world’s first Facebook branch of a bank, where you can live chat with tellers. (via Vaughn Davis)
- SciDB — GPLv3 NoSQL database. In addition to being multi-dimensional and offering array based scaling from megabytes to petabytes and running on tens of thousands clustered nodes, SciDB’s will be write once read many, allow bulk load rather than single road insert, provide parallel computation, be designed for automatic rather than manual administration, and work with R, Matlab, IDL, C++ and Python. (that from The Register) (via jsteeleeditor on Twitter)
- Twitter By The Numbers (Raffi Krikorian) — given to answer the question “what’s so hard about delivering 140 characters?”. They hit a peak of 3283 inbound tweets/second. Every time Lady Gaga tweets, 6.1M people have to get it. (via Alex Russell)
- EmoKit — an open source driver to the $300 Emotiv EPOC EEG headset. (via BoingBoing)
Big Dumps, 3D Printing Atom Movers, Faceted Browsing, and Useful Math
- Socorro: Mozilla’s Crash Reporting System (Laura Thomson) — We receive on our peak day each week 2.5 million crash reports, and process 15% of those, for a total of 50 GB. In total, we receive around 320Gb each day. Moving to a Hadoop-based system in the future, as they’re limited by database and filesystem storage.
- DIY Atomic Force Microscopy — use a 3D printer to make the parts so you can build a cheap and simple AFM head suitable for single molecule force spectroscopy. (via Vik Olliver)
