Sound over Network

For some years now we have a multiseat system based on Ubuntu (since it was initially very easy to set on). Moving to a new apartment made us think about how to place the furniture and most important the working desk (with the two workstations) as well as the speaker boxes. Until now the (Class A, SET vacuum tube) amplifier and the (also vacuum tube) DAC were on the desk with the speaker boxes placed on the two sides of the working table.
However, in the new apartment we decided to place the working desk in a corner. This brought up the question where to place the speakers. We decided to put them on a remote wall of the room. The problem was now how to control the sound from the common machine (client).

Why We Should Buy Music In FLAC

There is a discussion started today in Slashdot about using FLAC as music distribution format (instead of the currently widely used lossy formats, e.g. mp3). Here is my comment I submitted there:
I could understand some price differences in offering different qualities on a carrier (e.g. CD vs. DVD-A). But I definitely can not understand why I don't have the opportunity to buy the highest available quality.
Studio recordings are done in 24bit/192kHz and not in 16bit/44kHz. The difference is as audible as it is between mp3 (even at 320kbit/s) and 16bit/44kHz (CD quality) when you have equipment used to be called audiophile but easily available nowadays.
As long as 24bit/96kHz recordings are offered for $80 per album (see SACD and DVD-A prices), I will refuse to buy them. And I am not sure that this is the goal of the music industry. It is just that greed and stupidity run hand by hand.
Unfortunately the discussion about higher quality recordings is far from getting relevance, as we know that the most successful online music store price a song at $1. (On top of that they put also some restrictions on how you should use it.) At this price you could get a CD with CD-quality sound, carrier and a booklet. Still, this music store is so successful that the music stores almost disappeared from the streets.

Reflecting or sourcing light (E-Ink vs. LCD)

Electronic devices for reading long text files (e.g. eBooks) have become very fashionable in the last couple of years. One could wonder what changed for this to happen. After all flat screens have been around for some decades now. Portable flat screens also!

Tablet laptops (yes, they were called with the word "tablet") were produced at least for a decade now. With the introduction of the iPad, the tablets ran quickly into the consumers’ daily life. Charismatic as always, Steve Jobs presented the iPad about a year ago. The presentation was quite interesting because we know that Apple was hesitant whether to get into the market with Netbooks where Asus was making meanwhile a lot of profit with its Eee. Eventually they decided to offer something without a real keyboard in the same price range. Steve explained how you could listen to music (!) and see pictures (!!) on this new device. Incredible, those novelties! :)

Why not WP?

The ubiquitous use of WordPress nowadays makes it mandatory for consideration when one starts a new blog. And there are good reasons to choose WP among all the alternatives: it is open-sourced(!); it has the largest community, so support is not an issue; the zillions of plugins and themes allow making almost everything out of it; Matt Mullenweg (founding developer of WordPress) is a nice guy and has one of the coolest domains for his website: :)...
