Tool in Concert

Image0026-1Tool played the K-ROCK Centre in Kingston on Aug 4th.  The opening act was Tweak Bird – who managed to generate and impressive amount of sound with their 2 primary members (a 3rd joined them for a couple of songs on various ‘odd for a heavy metal band’ instruments: flute, sax).  If you want a sample of what they sounded like check out their MySpace page.

This was the 2nd time I’ve seen Tool in concert, and this was a very different experience than the last.  The 1st show I saw was in Ottawa at the Corel Centre, a much larger venue.  Also, this time we were in general admission (on the floor) vs. in seats.

The K-ROCK Centre has a concert capacity of 6500.  It was clear from the number of empty seats that this was not a sold out show, I’d guess it was somewhere under 6000 people.Image0022-1 On the left is a picture I took before the opening act – it gives you a sense of how small this venue is and how close we were to the stage (this was 3/4 of the way back from the stage).  The general (floor) crowd did get more tightly packed once Tool took the stage, but we ended up standing closer (about 1/2 between the sound board and the stage) and there wasn’t a crazy crush around us.  To be able to see a band like Tool in such a small venue was pretty amazing.

Tweak Bird was LOUD.  Tool was LOUDER.  I was glad to have my earplugs, but don’t get me wrong – I expect a concert like this to be very loud.  Feeling the bassline inside your chest is part of the experience.  Tool put on a great concert.  For more, check out these reviews of the Toronto show.

Book Review: Roo’d

Given the title, how could I not read this book?

I came across this book while browsing feedbooks using Stanza.  For the past couple of months I’ve been reading (free) eBooks almost exclusively.  At first I was using my NDS, and now my iPod Touch.  Primarily I’ve been reading material from the Baen Free Library, but lately I’ve moved over to feedbooks as they have a nice recommendation system which is how I found Roo’d.

I was hooked within the first few pages.  It was a fun and easy read, with plenty of actual technical jargon thrown in and for the most part the jargon was used in a way that made technical sense.  You do need to suspend disbelief a little with this story, and there are clearly areas where concepts from the Matrix and other popular sci-fi has been re-used and adapted.  It has a very similar feel to Little Brother, which is another eBook I’d highly recommend.

You can also purchase a hard copy of this book (paperback) from  I’m a little surprised by the somewhat hefty price tag on this, considering it is downloadable for free.  Still, it is nice to know you can get a ‘real book’ version of this – while I’ve been reading lots of eBooks, I still like real books.

The New Server

I had previously posted about the server than runs and that it had been given me trouble.   Well, the new parts came pretty quickly and it was a good thing – as just last week the old server packed it in.  It turns out that the most likely reason for the instability was the CPU fan, as it totally seized on the failure day and my CPU temperature climbed up past 90C.  An $8 fan might have solved my immediate problem, and been a lot less headache — having temperature graphs of the server would have helped spot this, something I plan to do with the new one.

At least I had a good excuse to buy new hardware.img_1086 So here is a picture of it hanging out in my furnace room next to the water heater.  While the new system is based on a MiniITX mainboard, I’ve opted to use a full size ATX tower case to house it (the case was a free hand me down from a friend).

I did modify the case quite heavily.  The stock fan grills were simply holes drilled in the case – it was more grill than not, so the airflow was pretty poor.  A couple of minutes with the dremel removed the grills entirely.  I also opened up the front bezel to provide easy inflow of air for the lower case fan.  The upper case fan is mounted to a pair of drive bay covers I’ve glued together.

This case has 6 x 5.25 drive bays, and 3×3.5 bays.  My system drive lives down in the bottom and the data drives are up where the top fan is.

I also cut a fan vent in the side panel to blow down onto the mainboard itself.  This I did with a jigsaw, and I think it turned out well considering it was my first attempt a something like this.

img_1071This older ATX tower case had all of the right connections for this new motherboard.  Power, reset and HDD connectors hooked up no problem.  The power LED was a 3 pin connector vs. the required 2 pin connector.  Karl was able to hook me up with a spare HDD connector that I spliced onto the power LED.

Since there were mounting locaimg_1074tions for 2 more exhaust fans, I couldn’t help myself and added two more at the top/back of the case.

If we count fans, I’ve got 5 case fans, 1 more in the power supply, and a chipset fan on the mainboard.  Overkill?  Yes. Required?  No, probably not.  There seem to be plenty of folk out there running exactly the same board with very minimal cooling.

My motivation here was the current system failing due to heat death, and I’d like this new system to run problem free for years.  The extra cost of a few fans isn’t a big deal, and its very quiet relative to the furnace.  I may further duct / optimize the cooling as the measurements thus far don’t show much of a delta from other peoples numbers on the net.

One more picture of the guts, to give you a sense of how small the MiniITX board is:

img_1070The transition from the old system to the new one should have been as simple as dropping in the drives and booting.  Unfortunately the old version of Ubuntu (Dapper) didn’t have support for the new Atom board and couldn’t make use of its network drivers etc.

Worse still, the system drive refused to boot in the new machine.  It is something that still has me scratching my head.  I even went to the effort of cloning the boot drive onto another which I had proven would boot with the new system – and still no go.  It was almost as if the MBR was in an unexpected location.  Last week I lost a bunch of sleep.

img_1075Above is a picture of the old server while it was cloning the boot drive (which as I mentioned, turned out to be a waste of time).  After five hours of beating my head on the problem, I simply moved the data drives to the new system – and did a clean install on a fresh boot drive.  The old server continued to host on the old system drive using the external fan to keep the CPU cool.

Yesterday I turned off the old server.  Here are a few URLs that I found helpful in the migration:

As I host a number of wordpress blogs here migrating them required a database backup / restore.  I simply copied over the /var/www directory data instead of re-installing the blog software itself.


mysqldump --add-drop-table -h localhost -u sql_username \
--password=sql_passwd sql_database_name > blog.bak.sql

Create DB on new host:

$ mysql -u root -p

mysql> CREATE DATABASE sql_database_name;

mysql> GRANT ALL PRIVILEGES ON sql_database_name.* TO “sql_username”@”localhost”
-> IDENTIFIED BY “sql_passwd”;


mysql> exit


mysql -h localhost -u sql_username  -p sql_database_name < blog.bak.sql

Well, if you’re still hanging in there – let’s talk about power consumption.  I borrowed Trent’s Kill-A-Watt meter and did some measuring.  My home desktop machine draws around 150Watts, and up to 200Watts of power when loaded (and using the CD drive).  The old server machine used 2W in standby, 120W during boot (loaded) and 112W steady state.  The new machine uses 1W in standby, a peak of 100W at boot (when the drives are spinning up), and 60W steady state.

In conclusion: Server machines need to have monitoring setup to track potential problems (temperature).  Migration of your data is less painful if you keep an install log with notes and links (thank goodness I did one last time).  New hardware usually needs a new software install, don’t fight it.
