  • I hate it when these things assume you know what the software does, it why I should care.

    Here you go:

    darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.

    Raw is the unprocessed capture straight from the camera’s sensor to the memory card, nothing has been altered. There are multiple alternatives in the open source world for raw development (ufraw, dcraw, rawtherapee) but darktable tries to fill the gap between the excellent existing free raw converters and image management tools (such as e.g. ufraw, rawstudio, f-spot, digikam, shotwell). It focuses on the workflow to make it easier for the photographer to quickly handle the thousands of images a day of shooting can produce. It’s also one of the very few FOSS projects able to do tethered shooting.

    The internal architecture of darktable allows users to easily add modules for all sorts of image processing, from the very simple (crop, exposure, spot removal) to the most advanced (simulation of human night vision).

    The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The main focus lies on user interaction, both in terms of a smooth interface design as well as processing speed. High quality output is also one of our goals.

    All editing is fully non-destructive and only operates on cached image buffers for display. The full image is only converted during export. Raw image loading is done using rawspeed, high-dynamic range and standard image formats such as jpeg are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).

    For a more complete list of darktable’s current features have a look at the features page. Or – even better – just install it and try it out!




  • I agree with this and do not dispute it.

    However, I think there is value to the human mind in performing ritual, meditation, and positive thinking. We can think ourselves into feeling better. The placebo effect works, even in you know about the placebo effect.

    Jesus didn’t know about these things 2000 years ago, but the stories about him make him seem like a worldly rabbi. He might have seen evidence of people getting better from disease through the power of prayer. (Never amputees, though.) The human body can fight disease; it can never regrow a limb.

    The human mind also tends to remember positive experiences, and tends to ignore things that don’t seem to work. This is how fake psychics and cold readers work. You send out a bunch of guesses, and get a couple of “hits”, and the client remembers the hits. We all remember the hits. It’s harder to remember the misses. (Side note: I experienced a palm reader at a party and experienced this first-hand, and despite knowing their techniques, I still felt it a little.)

    All this makes me believe that our brains are generally susceptible to a construct like religion. And that there could be some value in meditation, ritual, and positive thinking. However religion is frequently a grift and makes people do bad things - it doesn’t have to be, though. Being quietly spiritual is ok, which is what Jesus taught.













  • Clojure is an interesting language that will improve the way you work and think with other languages. A passionate community, but there are very few “starter” Clojure jobs; they mostly expect you to have years of experience.

    I don’t think anyone could go with doing the “Clojure For The Brave And True” book which is online and available in dead-tree form. I liked it so much, I bought the book.

    It’s a Lisp language which is the oldest kind. Instead of “object oriented”, I think if it as verb oriented. Each statement is a verb (function) possibly followed by all the nouns you want to apply it to. Easy peasy, right?

    People complain that there’s “too many parentheses”. People like to complain about dumb stuff.
