Souders Joins Speedcurve — During these engagements, I’ve seen that many of these companies don’t have the necessary tools to help them identify how performance is impacting (hurting) the user experience on their websites. There is even less information about ways to improve performance. The standard performance metric is page load time, but there’s often no correlation between page load time and the user’s experience. We need to shift from network-based metrics to user experience metrics that focus on rendering and when content becomes available. That’s exactly what Mark is doing at SpeedCurve, and why I’m excited to join him.
3 Steps for Licensing Your 3D-Printed Stuff (PDF) — this paper is not actually about choosing the right license for your 3D printable stuff (sorry about that). Instead, this paper aims to flesh out a copyright analysis for both physical objects and for the digital files that represent them, allowing you to really understand what parts of your 3D object you are—and are not—licensing. Understanding what you are licensing is key to choosing the right license. Simply put, this is because you cannot license what you do not legally control in the first place. There is no point in considering licenses that ultimately do not have the power to address whatever behavior you’re aiming to control. However, once you understand what it is you want to license, choosing the license itself is fairly straightforward. (via BoingBoing)
Jane Jacobs on Strangers (Nina Simon) — Many of us live in towns where we rarely have the opportunity for this kind of anonymous, safe, positive social contact. This is a problem. It means we smile less at strangers. We take care of each other less. We fear it opens up a social contract for too much more. There’s an analogous gap in online social media, where it feels like there are all too few social contract-building public Internet spaces.
PANDA — an open-source Platform for Architecture-Neutral Dynamic Analysis. It is built upon the QEMU whole system emulator, so analyses have access to all code executing in the guest and all data. PANDA adds the ability to record and replay executions, enabling iterative, deep, whole system analyses. Further, the replay log files are compact and shareable, allowing for repeatable experiments.
From Gongkai to Open Source (Bunnie Huang) — The West has a “broadcast” view of IP and ownership: good ideas and innovation are credited to a clearly specified set of authors or inventors, and society pays them a royalty for their initiative and good works. China has a “network” view of IP and ownership: the far-sight necessary to create good ideas and innovations is attained by standing on the shoulders of others, and as such there is a network of people who trade these ideas as favors among each other. In a system with such a loose attitude toward IP, sharing with the network is necessary as tomorrow it could be your friend standing on your shoulders, and you’ll be looking to them for favors. This is unlike the West, where rule of law enables IP to be amassed over a long period of time, creating impenetrable monopoly positions. It’s good for the guys on top, but tough for the upstarts.
Solar Hits Parity in 10 States, 47 by 2016 (Bloomberg) — The reason solar-power generation will increasingly dominate: it’s a technology, not a fuel. As such, efficiency increases and prices fall as time goes on. The price of Earth’s limited fossil fuels tends to go the other direction.
Facebook’s Top Open Data Problems (Facebook Research) — even if you’re not interested in Facebook’s Very First World Problems, this is full of factoids like Facebook’s social graph store TAO, for example, provides access to tens of petabytes of data, but answers most queries by checking a single page in a single machine.

The Care and Feeding of Weird Machines Found in Executable Metadata (YouTube) — talk from 29th Chaos Communication Congress, on using tricking the ELF linker/loader into arbitrary computation from the metadata supplied. Yes, there’s a brainfuck compiler that turns code into metadata which is then, through a supernatural mix of pixies, steam engines, and binary, executed. This will make your brain leak. Weird machines are everywhere.
European Libraries May Digitise Books Without Permission — “The right of libraries to communicate, by dedicated terminals, the works they hold in their collections would risk being rendered largely meaningless, or indeed ineffective, if they did not have an ancillary right to digitize the works in question,” the court said. Even if the rights holder offers a library the possibility of licensing his works on appropriate terms, the library can use the exception to publish works on electronic terminals, the court ruled. “Otherwise, the library could not realize its core mission or promote the public interest in promoting research and private study,” it said.
Laws of Crappy Dashboards — (caution, NSFW language … “crappy” is my paraphrase) so true. Not talking to users will result in a [crappy] dashboard. You don’t know if the dashboard is going to be useful. But you don’t talk to the users to figure it out. Or you just show it to them for a minute (with someone else’s data), never giving them a chance to figure out what the hell they could do with it if you gave it to them.
PlotDevice — A Python-based graphics language for designers, developers, and tinkerers. More in the easy-to-get-started + visual realm, like Processing. (via Andy Baio)
Scumblr and Sketchy Search — Netflix open sourcing some scraping, screenshot, and workflow tools their security team uses to monitor discussion of themselves.
Should Twitter, Facebook and Google Executives be the Arbiters of What We See and Read? (Glenn Greenwald) — In the digital age, we are nearing the point where an idea banished by Twitter, Facebook and Google all but vanishes from public discourse entirely, and that is only going to become more true as those companies grow even further. Whatever else is true, the implications of having those companies make lists of permitted and prohibited ideas are far more significant than when ordinary private companies do the same thing.
slic3r — converts a digital 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
gCodeViewer — GCode is the “numerical control language” for telling extruders, mills, polishers, etc. where to move to and when. This open source package is a visual GCode visualizer, viewer and analyzer in your own browser! It works on any OS in almost any modern browser (chrome, ff, safari 6, opera, ie10 should work too). All you need to do – is drag your *.gcode file to the designated zone.
AC Power Control with Arduino — in the video video and the code, we take an in depth look at the hardware for using Arduino interrupts to control AC power through a triac. Using a zero-crossing detector Arduino will detect the pulse then calculate a delay to control the power output to a load.
OpenRefine — (edited: 7 Dec 2013) Google abandoned Google bought Freebase’s GridWorks, turned it into the excellent Refine tool for working with data sets, now picked up and developed by open source community.
CC 4.0 Out — The 4.0 licenses are extremely well-suited for use by governments and publishers of public sector information and other data, especially for those in the European Union. This is due to the expansion in license scope, which now covers sui generis database rights that exist there and in a handful of other countries.
Algorithms and Accountability — Thus, the appearance of an autocompletion suggestion during the search process might make people decide to search for this suggestion although they didn’t have the intention to. A recent paper by Baker and Potts (2013) consequently questions “the extent to which such algorithms inadvertently help to perpetuate negative stereotypes”. (via New Aesthetic Tumblr)
