THE LOST HERO by; Rick Riordan. Reviewed by Daniel

I loved Lost Hero These are the three main characters: Jason, Piper and Leo.

When Jason woke up on the school bus, he had amnesia.

Piper's dad has gone missing. She has a really big secret she doesn't want to share. It's about her dad.

Leo has a way with tools. Ever since he got to Camp Half Blood and he saw all the kids with all the machinery, he forgot about leaving.

There is a missing camper.

I recommend this book to people who like adventure stories.

I like this story because it's an adventure story with lots of Greek myths and monsters and it's part of the Percy Jackson series.

i forgot an important one!

 
I read it last January and it still haunts me. The characters. The prose. The story. City Of Thieves by David Benioff manages to be devastatingly tragic, powerfully hopeful and sharply funny. It's on the list of my life-time favourites.

Please forgive the hyperbole.

I just can't believe I forgot this book when I wrote up yesterday's list. Set during the first world war and the siege of Leningrad, City of Thieves tells the story of a young Jewish man who, in order to save himself, must find eggs - to be used to make a wedding cake for an officer's daughter - during a time of famine. His companion on this quest is a worldly Russian soldier and aspiring writer. The two men encounter the best and worst of human character and become the most unlikely of friends.

This one is beautiful.

New theme for Kingston-Wayne.ca

We have changed the theme. The new theme is probably just as dull as the previous theme. But NEW!

I have returned the voltmeter

My time with the Ottawa Public Library's Kill-a-Watt meter has come to an end. It was fun and informative. My final measurement was of my stereo system while not in use. With all my components (amplifier, CD player, turntable) off, or rather on stand-by,  my stereo draws 17 watts of power.

I will have to re-order the meter from the OPL when I have more time.

The Kill-a-Watt meter is one example of a non book or other media item the OPL has available.

 

Take a look at http://biblioottawalibrary.ca/en/main/find/catalog/search/all/realia for more items.

Shocking Voltmeter News!

Well, I was a little shocked.

 

I have been having a running discussion on monitor power usage. When flat screen monitors first came out I was told that they used less power than the old CRT monitors. Lately I've been told that large flat screen monitors actually use more power than large CRT monitors. So, having the means to test this, I did!

I currently use two Dell 19" flat screen monitors. To make the test fair I unplugged one flat screen and connected a Sony Trinitron 17" CRT monitor. I have also heard that a white screen uses more power than a black screen, so I tested that as well. 

  White Screen Black Screen
Flat Screen

28 watts

.37 amps

29 watts

.39 amps

CRT

86 watts

1.03 amps

63 watts

.78 amps

 

The results were clear. Flat screen monitors at this size use less power than CRT monitors. The shocking results?  While black screens may use less power than white in the old CRT world, the opposite is true with flat screens.

Kill-A-Watt

While browsing the Ottawa Public Library site I noticed that they had watt meters available for borrowing. These are the kind of meters you can plug into the outlet and then into which you can plug various electric devices. I put one on hold and it arrived less than a week later.

I've been curious for a while about the actual draw of the many electronic devices we have, especially when in 'standby mode'.

How much electricity does it take to run the VCR's clock?

What is the difference between a computer in 'sleep' mode versus a computer in 'hibernate'?

How accurate are the watts/amps on the device's labels?

What uses more power a flat screen monitor or a CRT monitor?

Now I can find out!

 My first project was to check out my computers.

Computer Electricity Usage

When measuring the computer electricity usage I noticed that the numbers varied quite a bit depending on what the computer was doing. Booting up took more power than idling. Anytime the hard drive was accessed the numbers jumped up. The numbers below are averages of a few seconds of observation. Where there was a large spread I have given the spread as best I could observe. I assume that there are probably other factors I didn't consider that may affect usage.

Laptop

  Watts VA Amp
Laptop Sleep Mode .03 14 .13
Laptop On 53 93 .70
Laptop Hibernate .03 14 .14

 

Desktop

  Watts VA Amp
Desktop On  60-80  93-117  .77-1.00
Desktop with Flat Screen  80-90  158  1.11
Desktop with Two Flat Screens  110-120  164-185  1.36
Desktop with Monitors and External Hard Drive (running) 120-130 119 1.5
Desktop with Two Flat Screens and iPhone plugged into USB port 115 177 1.47

 

It turns out that usage varies quite a bit and seems to depend on what the computer is doing. If I were testing multiple computers for comparison I would have to be pretty rigorous in my approach to ensure that each computer was working the same. It does make me wonder if different operating systems would have different electricity usage. Plugging and unplugging my iPhone had a small but measurable effect on usage.
