  • Dodecahedron Speaker Is Biblically Accurate

    Once upon a time, many radios and TVs only came with a single (mono) speaker. Then someone decided all audio hardware should have as many speakers as we have ears. That was until [Olivia] came along, and whipped up a dodecahedron speaker as an educational piece for workshops. Really, it shows us that twelve speakers should be the minimum standard going forward.

    The speaker relies on a 3D-printed frame. The dodecahedron shell is assembled from 12 individual faces, each of which hosts a small individual speaker. Multichannel audio fans shouldn’t get too excited—all twelve speakers are wired to the same input in four groups of three, making this essentially an exceptionally complicated mono device. It might sound silly, but it’s actually a great way to deliver audio in many directions all at once. [Olivia] even went to the effort of running some sweep tests in anechoic and reverberation chambers to see how they performed, which is a fun bit of extra detail in the build log.

    [Olivia] notes that these unique speakers are great as a beginner workshop build. They’re easy to modify in various ways to suit different ideas or levels of ability, and they can be made for less than $30 a pop. We’d love to see an advanced version that maybe packed in a lithium battery and a Bluetooth module to make them a standalone audio device. Video after the break.

    I enjoyed and appreciated reading this post.

    "I realized almost immediately that GNU/Linux and FreeBSD were so similar they were completely different."

    This right here.

    My initial impression with in 2006 was quite similar. Of course, back then was a much different beast than what it has evolved (mutated?) into today.

    Had I not pursued Linux system administration as a career, I *probably* would have stuck with FreeBSD.

    We can make all the technical comparisons between the two OSes all day long but what drove my interest and enthusiasm are (1) the documentation and (2) the community.

  • @stefano Don’t bother filing a bug report. They will act stupid. Probably they are stupid about it. They think it is a bug. Actually the author probably wrote a program he knew was not a solution to the problem but which he could do on deadline and which was good enough for his job at HP.

  • @stefano Here is something new for you to be upset about, though, which affects everyone, Linux, BSD, illumos alike. I have been upset about it for over 20 years.

    Read ‘man 5 fonts-conf’ or whatever your equivalent is. Read it carefully under ‘FONT MATCHING’. What it says is that a font is not chosen as you wished, but instead RANDOMLY. You are only LUCKY if you get the font you wished.

    And if you experiment long enough you will find this is true.

    Fontconfig is unfixable and must be scrapped.
