House of Suns

House of SunsA very different book by Alastair Reynolds. In this book humans have long colonized our galaxy and split into many different sub-species and sub-civilizations. One such sub-civilization is the shatterlings. They are clones who’s purpose are to explore the galaxy. The particular faction we follow are all clones of a woman who’s childhood is one of the parallel storylines in the book. These clones live for millions of years, both due to relativistic time dilation and cryogenic technology. But something threatens their existence, most of them are killed in an attack, and the survivor are left to figure out what happened.

The setting of the book is brilliant, but this time I think Reynolds got a bit lost in his storylines. I felt too much time was spent on less significant tracks, and too little on the conclusion. The end of the book comes really fast and while magnificent, a bit hasty. Still a very good book.

Absolution Gap

Absolution GapCatching up on my book reviews, so here is yet another book I just read by Alastair Reynolds. This book is the continuation of the story in “Redemption Ark”. In that book we left a shipload of refugees on a habitable planet after fleeing from the Inhibitors, a machine intelligence who’s task is to prevent intelligent civilizations to arise in our galaxy in an effort to prevent galactic wars. In “Absolution Gap” they’ve caught up with our refugees. We follow these people as well as the story of a man employed by a Conjoiner to survey solar systems for treasure. He has a religious experience involving a gas giant that seems to periodically vanish from existence for a fraction of a second. On an orbiting moon he forms a cult of believers who sole purpose in life is to observe such a vanish. The two storylines meet at the end to form a grand finale.

I have to say I enjoyed this book the most of the 3 Revelation Space books involving the same characters. The characters in this book are even more colourful than the previous, and the story is entertaining and involving in every substory and side tracks. Reynolds description of futuristic technology is more imaginative than ever, and his attention to details is as great as always.

New Media Centre PC!

Chieftec HM-03Well, I had already bought new hardware for my Media Centre PC  a couple of months ago, but this week my good old Silverstone HTPC box died (or the PSU did). I looked a bit around and landed on the Chieftec HM-03B box and a 400W PSU. The box is just fantastic. Has plenty of room, though it only takes a micro-ATX mainboard and low profile expansion cards. The HM-02 box is taller and probably takes the full size expansion cards, though I didn’t really care as I don’t need any additional cards. Anyway, the box comes with a display, a volume and selector knob and a remote. All connected through a single USB cable which fits onto one of the USB connectors on the mainboard.

ASUS M4A785D-M PROIn addition to the box, I run this setup of an ASUS M4A785D-M PRO mainboard, with a AMD Athlon II X2 240 CPU. Now I’m a long time fan of both AMD and Asus, and generally only buy their hardware. In any case, the Asus mainboard has a ATI Radeon HD 4200 graphic chip and a 7.1 HD audiochip built-in. The GFX card uses shared memory, which is not a problem as I run 2GB of Crucial DDR2 PC5300 RAM. The mainboard has VGA, DVI and HDMI connectors, so I bought a HDMI cable as my now ageing 32″ LCD TV supports 720p. I have to say it was amazing how much difference the HDMI cable made compared to the VGA. The picture suddenly became crystal clear.

With the addition of a Blue ray drive and a used SATA-II HD, my setup is complete. It is installed with Windows XP. I had a spare key around, so I saw no reason to run any heavier OS. I don’t run Windows Media Center, can’t stand the software. Instead I run XBox Media Center (aka XBMC) which I will write a review of on its own later.

First Collisions in the LHC

 

CMS data at LHCYesterday a test run of the Large Hadron Collider at CERN produced the first collisions and collision data after 20 years of construction and preparations. They produced collisions in ATLAS, ALICE, CMS and LHCb. The beam was running at injection energy, so no acceleration. Next steps will be to crank up the power. This is looking promising so far, and I hope it all runs well. People were really excited here at the Institute of Physics in Oslo yesterday when they followed the unexpected test run online. Too bad I wasn’t there myself at the time, so I didn’t get to see the live feed.

How to stop the damn commentspam!

captchaI got fed up with the comment spam I get on my blog. I googled a bit and found a few solutions, but ended up with a plugin that adds CAPTCHA to the comment form.This little gem can be downloaded from here.

It is fun to observe the spammer-scripts bang their virtual heads against this simple little tool. I can observe all the spam attempts in my website log. :)
