Submission + - Texas likes open source, doesn't understand it 2

emerika writes: The state of Texas has issued a request for offer that is embarrassing to read. On the surface, they want to invest in open source textbooks; however, the RFO is littered with statements like: "A state-developed open-source textbook is the property of the state".

Particularly annoying, and an ongoing problem, is that they have written their own definition of open source: "As defined by statute, an open-source textbook is an electronic textbook that is available for downloading from the Internet at no charge to a student and without requiring the purchase of an unlock code, membership, or other access or use charge, except for a charge to order an optional printed copy of all or part of the textbook."

Further evidence of their lack of understanding here: "The Commissioner of Education (COE) may provide a license to use a state-developed open source textbook to an entity not listed. In determining the cost of the license, the COE shall seek, to the extent feasible to recover costs of developing, revising, and distributing state-developed/state owned open-source textbooks."

Is RawTherapee an interface for dcraw?

No. RawTherapee uses dcraw only for decoding of the raw files. It is not commonly known, but dcraw is the basis of the decoding engines of almost all raw converter software (including Photoshop, LightZone, RawShooter, etc.).

All the algorithms of the image processing steps (including the demosaicing) are RawTherapee's own methods.

The only advantage of lithium batteries is high energy density, which is irrelevant for a static installation. For powering something as long lasting as a house it would be better to use something more robust. Nickel-iron batteries have low energy density but are very robust. I wouldn't want a house battery I'd have to replace every few years.

Submission + - Google says ad blockers will save online ads (theregister.co.uk)

azoblue writes: Google — the world's largest online ad broker — sees no reason to worry about the addition of ad-blocking extensions to its Chrome browser. Online advertisers will ensure their ads aren't too annoying, the company says, and netizens will ultimately realize that online advertising is a good thing.

Ardour is the only Free software DAW suitable for any serious work. It uses JACK, which is an excellent low-latency audio routing system, but actual audio playback on Linux depends on the ALSA backend, which varies in quality depending on your hardware. Check the Alsa SoundCard Matrix for details. Recent Linux kernels have reasonably low latency by default, but for very tight latency requirements you might need a custom kernel configuration or patches.

E-ink displays have very bad contrast ratio. Typically about 10:1, compared to 1000:1 or more for an LCD. The only visual advantage of e-ink is higher DPI, which is a marketing based rather than technical benefit because there's no reason LCDs can't have just as high DPI (see the OLPC XO1's display, which is also reflective so it's usable in sunlight).

E-ink is a dead-end technology. Bistable LCDs will exceed it in ever aspect. Ferro Liquid Display technology looks promising.

Consistent fonts are a good thing. People argue over hinting and serifs and kerning and the like, but the single most important factor in font legibility is familiarity. Always use the same font and you'll read faster and more accurately. This is a big reason why I prefer to read on screen.

Submission + - Bing Censoring all Chinese Language Querys (nytimes.com) 2

boggis writes: Nicholas Kristof, a New York Times journalist is calling for a boycott of Microsoft Bing (so don't click that link). They have censored search requests at the request of the Chinese Government (like certain others). The difference is that Bing have censored all searches done anywhere in simplified Chinese characters (The characters used in mainland China). This means that a Chinese speaker searching for Tiananmen anywhere in the world now gets the impression that it is just a lovely place to visit.
