Neu! Jetzt auch auf Deutsch!

Filed under: personal — Tags: — Yeti @ 0:19

Da mir einige bloggenswerte Sachen in den Sinn gekommen sind, bei denen es keinen Sinn hat, die auf Englisch zu veröffentlichen, habe ich mich entschlossen, ein deutschsprachiges Blog – ebenfalls hier auf WordPress – anzulegen. Bitte hier entlang!

Because some things I consider worth blogging have absolutely no impact to the anglophone world, I decided to create a secondary blog in German.

I will still mostly blog here, though.

Vacation Reading List

I have been on vacation for the last three weeks now, thus the decline in my posting frequency …

The first thing I usually do when I know that I have a few weeks to spare, is to go out and buy a heap of books (mind-fodder, munch, munch).

Following is the list I purchased two and a half weeks ago – in no particular order, if I get the time, I will comment on one or the other when I have read them (I’m already through some of them … they’re written in green, the one I’m reading at the moment is in red):

  • Bjorn Lomborg
    Cool It! The Skeptical Environmentalist’s Guide to Global warming.
  • Michel Onfray
    Traité d’athéologie. Physique de la metaphysique.
    (Wir brauchen keinen Gott. Warum man jetzt Atheist sein muss.)

    (We Don’t Need A God. Why One Has to be an Atheist Now. – re-translation of the German title)
    (Treatise on an Atheology. Physics of the Metaphysics. – direct translation of the French title)
  • Ray Bradbury
    The Martian Chronicles
  • Philip K. Dick
    A Maze of Death
  • Harald Lesch and Harald Zaun
    Die kürzeste Geschichte allen Lebens

    translation of the German title)
  • Julia Friedrichs
    Gestatten: Elite – auf den Spuren der Mächtigen von morgen.
    (May I Introduce Myself: Elite – On The Trail of The Powerful of Tomorrow
    – translation of the German title)
  • Dietmar Wischmeyer
    Logbuch, Das Schwarzbuch der Bekloppten und Bescheuerten.
    (Logbook, The Black Book of The Nutty And The Crackbrained
    – translation of the German title)
  • Douglas Adams
    Mostly Harmless – Part Five of The Trilogy
    (Einmal Rupert und zurück
    – German title)

Yeah, I know, I read a lot, maybe too much at times …

Optical Illusion

Filed under: Uncategorized — Tags: , — Yeti @ 23:12

Wow, while tag-surfing during re-read of my last blog entry, I discovered this:

Private Projects

Filed under: Computer, Simulation — Tags: , , , — Yeti @ 22:57

I present a list of some of the private projects (not only programming, some of them involves hardware) I’m currently working on. This blog entry will also stay here as a permanent (and – hopefully – growing) page.

When I get around to it, I will create sub-pages pointing to more information regarding the particular project, but for now I will only list them here with my working title and a short description of what they’re good for (or will be at some diffuse point in the future).

Watch the pages-entry to the right.

So here we go …


That’s the one into which I have put most of my current effort. It simulates the functioning of a (smallish) brain by mimicking the inner workings of real neurons to the extent that I thought made sense. It has an unlimited set of types of neurons, (more…)

C# (or .NET) Really Helps

Filed under: .NET, Computer, Programming Languages — Tags: , , , — Yeti @ 7:25

Some time ago, I realized why I really like C# (or .NET, for that matter), now I decided to try and put it into words.

I program a lot. I mean, an awful lot, really. Just as a brick-layer layers an awful lot bricks, because that’s what he does all day. Modularity has always been one of my concerns, but it never really worked up to the point of really reusing code. I mean reuse as in: just use it again. Full-stop. And not, “oh, I did something similar some time ago, I’ll just copy ‘n paste this stuff into this project and adapt it to my current needs”.

Curiously enough, since I started to rely heavily on managed code and, more specifically, on C# instead of good-ole C++, ever more pieces have started to fall into ever more places where they seem to fit … (more…)

Dead Mice – What Cats Do At Night

During the warmer months of this and last year (since I abandoned my rented apartment in the city in exchange for my own house in a rather smallish village …), my two cats (Simba and Karlo) typically were and are out of office every night. In the morning, just about a few milliseconds after I have filled their feeding dishes, they come flying through the open kitchen window, arriving for breakfast and then sleeping most of the day out of sheer sloth to recover from the hardship of their outdoor jobs. During the nights, they occasionally waltz in to report on how their business is going.

This means that, during the course of an average summer night, I have to dispose of several (mostly/almost) dead mice; shrews, field-mice and what-not (where does one dispose of dead mice, or what remains of them, respectively?). (more…)

Concurrency Helper – Classes

I have updated my concurrency-page.


… If a thread does a Deqeue() on an empty queue, it is blocked automatically until someone Enqueue()s a new item into the queue. Several threads can access the ThreadBlockingQueue at the same time, regardless if it is a read- or a write-access …

Hydrogen Power on the Cheap–Or at Least, Cheaper: Scientific American

Filed under: energy, Uncategorized — Tags: , , , — Yeti @ 20:46

I just came across this:

Hydrogen Power on the Cheap–Or at Least, Cheaper: Scientific American.

I’m underwhelmed.

It’s just a way to get a cheaper electrolysis – device. Not some new orders of magnitude of efficiency. And the inventor dreams of revolutionizing our energy-economics within a decade. Seems there are different positions regarding if it makes sense to build a totally new infrastructure to create, distribute and consume hydrogen or if it’s more clever to store and use the electricity (that’s needed to split water into hydrogen and oxygen) directly.

In terms of personal transportation, what it all comes down to is the question if there will be effective batteries (meaning storing at least, say, 50 kWh – which would be the equivalent of some 5 liters of gas and weighing no more than about 100 kg, maximum recharge time 5 minutes). I hope for the latter. In my opinion, following the hydrogen way is following the wrong track.

The argument is about that simple: Hydrogen is much more difficult to store and distribute than is electricity – given the batteries suit the case.

A Poem To Cats

Filed under: Kittens, Life Universe and All the Rest — Tags: — Yeti @ 13:00

I’ll just post this “as is”. I wrote this – ahem – poem about three years ago (2005) when I got my second cat and just felt incredibly inspired …

Please note that this is my first and last and always poem I’ve ever written!

It is in German, I’ll try to translate it, but I guess it will lose all of – what? what has it got? – what it’s got in the process. It mostly consists of rhyme and beat – in and out of rhythm, but I didn’t care at that time, I just wanted to express my thoughts concerning my two cats. For now, I’ll just provide a translation that keeps the tenor (and beat) of it, but in no way rhymes or feels like the “real thing” …

Hope you enjoy … (more…)

A Blog Of Kitten Pictures …

Filed under: Kittens — Tags: , , — Yeti @ 1:17

OK, right now I’d like to introduce my cats, named ‘Simba’ and ‘Karlo’.

They both are quite ordinary farm cats (tomcats to be specific) that I ‘rescued’ from being drowned in a bucket if no one had ‘adopted’ them. One of them, Simba, is a light-/dark- gray tabby cat, the other one (Karlo, named after “Black Pete” of Disney’s, just because he looks so … and is called ‘Kater Karlo’ in the German versions of Disney’s Comics), over here he would be described as a so called ‘cow-cat’, because of his painting …

Just before it gets too boring for any possible reader of this post, here are the pictures:

This used to be the place where my TV-set rested ...

This used to be the place where my TV-set rested ... Introducing: Karlo!


This is my favourite, just because it's my first one ... Introducing: Simba!

The reason I’m just now writing about my irrelevant cats is the following:
Simba got engaged in a heavy fight last night and got severely injured at the base of his tail. Tomorrow I’m taking him to the vet, and to prepare for it, I took his cat-carrier and placed it in my living-room to get him acquainted to it (again). Guess what happened? Right now he’s sleeping happily in it and I think I’ll just have to close the lid tomorrow morning
and can get off to the vet.
It could have been much harder, believe me, this is not the first time to take him to the vet …
