Alternate method of erasing CDs

Sure, anyone can grab a screwdriver and scratch the top off a burnable CD, making it unreadable for all but the most determined hackers ... but to REALLY do the job properly requires a bit more equipment.

Watch how this high voltage hell raiser from across the pond gets the job done:

New hardware installation ...

This is another kind of support structure & despite its importance to me I can honestly say I slept through the whole installation. The material is titanium I believe and it'll probably cost about as much as a Rohn Tower.

The celebratory beer might have to wait until I've backed off on the pain killers but it'll be a happy day once this whole thing is complete, believe me!

Limited space creates a demand for electronic books

Collecting vintage & antique books is a relatively inexpensive hobby, as long as you have space to store and display the books! It occurred to me a while ago that I should scan my books, both for preservation reasons and also, where copyright allows, so they can be shared and enjoyed by others.
In a country where space is at a premium Japan has gone where I couldn't bring myself to go and several conversion services are springing up that cut the spines from books and then scan the stack of pages to electronic formats. The books are then thrown away so they cannot be sold as second hand, this is literally a conversion service!
The book scanners that interest me are non-destructive and use a angled tray to hold the book while two cameras take pictures of the opposing pages. It is much slower than the above mentioned process but the only method I would consider with rare books.

Feb. 4 (Bloomberg) -- Japan’s cramped living conditions and the arrival of Apple Inc.'s iPad in May have spawned as many as 60 companies offering to turn paper books into e-books as Japanese publishers have been slow to provide content for new electronic readers.
The country's $24 billion market for paper books and magazines, the world’s largest, may see an explosion in e-books as Samsung Electronics Co.’s Galaxy Tab tablet computer and readers by Sharp Corp. and Sony Corp. take on Apple Inc.'s iPad. Mike Firn reports from Tokyo for Bloomberg Television.

Listening to history ....

With careful tuning I can listen to single sideband signals on my old Hallicrafters SX-25 receiver. The longer it is left on the more stable its internal oscillators become and it will "drift" less. When it drifts the frequency the radio is tuned to changes slowly requiring constant retuning ... just part of the charm of these old boat-anchors.

Flying practice.

A few days ago I decided to restart my morning bike rides. This means getting up at 5AM (I'm not a morning person so this is a struggle) and going for a 1 hour ride around the neighborhood.
The particular ride was cut short as I encountered an unexpected change in ground level and was sent sailing over the handle bars only to break my fall a few seconds later with my elbow.
A bone in my elbow, not usually subjected to this type of punishment, broke off and took up temporary residence quite a way from its original home. Since tendons that help my arm to move were attached to this bone I found myself riding one handed back to the house.
A few xrays later it seems as though I'll be having some surgery soon to reattach pieces of bone back together with whatever titanium bits the doctor deems necessary. In the meantime I'm consuming the minimum pain relievers required to take the edge of the pain without turning into a zombie.

This is what a normal elbow joint should look like.
