Wrapping up Speeds and Feeds, part 3: Ruggedness

As I continue to wind down Speeds and Feeds, I picked ruggedness as the topic for part 3.

In part 2 of this wrap-up series, I on Tuesday discussed reliability, suggesting that an increasing portion of the transistor budget in personal computers should be used to avoid, detect, and recover from hardware, software, and data errors.

Ruggedness, the ability of a PC to survive adverse physical conditions, complements reliability by further increasing the practical availability of a PC to do useful work.

As with efficiency in power management (part 1's topic), this is an area where PCs can learn … Read more

Books for practical mechanical engineering

I've mentioned the Homebrew Robotics Club here a few times. The club has an active mailing list. And when I found myself writing a lengthy post there over the weekend, I figured it might be of interest to the wider audience.

The post was in response to this inquiry from club president Wayne C. Gramlich, included here with his permission:

Can anybody point me a book that goes into design issues associated with assembling mechanisms out of bearings, axles, and gears? I'm looking for pretty basic stuff, like when to use a ball bearing, where to place bearings … Read more

Intel and TSMC: What are they thinking?

Don't get me wrong-- I think the Intel-TSMC alliance announced earlier this week is a good thing for both companies.

But the official explanation, that Intel wants TSMC's help to make Atom processor cores more widely available to the industry, just doesn't strike me as a sufficient reason for the deal.

Intel hardly needs TSMC's help to make SoCs (systems on a chip). Intel has been making highly integrated devices for the embedded market, as well as PC chipsets for a long time. It already has enough of the building blocks and enough experienced engineers to … Read more

Researching notebooks for medical research

I received an interesting e-mail from a reader over the weekend. Dr. Katherine Gold, a lecturer with the Department of Family Medicine at the University of Michigan, had some questions related to Netbooks (or small notebooks), broadband Internet access, and physical computer security. After some discussion, Dr. Gold and I decided to see if some of you might be able to help answer her questions.

Here's the situation: Dr. Gold is setting up a research project to investigate the benefits of online support groups for low- income women in the Detroit area who have recently suffered the loss of … Read more

Notebook news from MacWorld Expo

I suppose most of the excitement from MacWorld Expo has died down by now, but I'd still like to talk a little about two new Mac laptops introduced at the show-- Apple's own 17" MacBook Pro, and Axiotron's Modbook Pro, a tablet computer made by repackaging the components from Apple's 15" MacBook Pro along with some new parts.

First, the Axiotron product. Externally, the ModBook Pro is radically different from the Apple notebook that provides most of its component parts.

In this publicity photo, the Modbook Pro's beveled edges are apparent. The shape … Read more

Hands-on with the new MacBook Pro

When Apple announced its new notebooks on Tuesday, it said the new machines would be in the company's retail stores the next day.

So I went to the Apple store at the Westfield Valley Fair mall in Santa Clara, Calif., after work on Wednesday. I got there a few minutes after 6 p.m. and discovered that an Apple technician was in the process of replacing an old MacBook Pro with the first one of the new models.

I positioned myself authoritatively about a foot from the tech's left elbow, so when he was done, I was the … Read more

E-books: The flexible future

Interesting news from the DemoFall conference held this week in San Diego:

Plastic Logic--a company founded to commercialize electronics built on flexible plastic substrates--demonstrated a prototype e-book reader (not yet named) and announced that it plans to ship this product in the first half of next year. You can read the press release for yourself.

This particular gizmo is very attractive. It uses a large, flexible electronic paper display based on technology from E Ink (the same company that makes the displays for Amazon.com's Kindle and Sony's Reader), but the device overall is remarkably thin and light.

And the whole thing is somewhat flexible, so it won't break if it gets slightly bent in a backpack or briefcase. Flexible doesn't mean invulnerable, but it's a lot better than the brittle glass displays of existing e-book readers.

Check out this video from DEMOfall, in which Plastic Logic CEO Richard Archuleta demonstrates the prototype. I see some minor problems in the prototype's display--some dead lines and odd drawing glitches--but nothing that should interfere with the scheduled launch.

More importantly, even as a prototype, the display's contrast ratio seems to be better than that of the Kindle or Reader, mostly by virtue of the white being whiter--I'd have to make a direct comparison to be sure, though. I also see all of the critical features I want in an e-book reader: good display resolution… Read more

A practical consumer fuel cell, coming soon

At CES 2008, I talked with several companies, some for work and some for Speeds and Feeds.

Although I saw many interesting products, I'm really looking forward to one product in particular that isn't due to ship until October.

It's the HydroPak fuel-cell power supply from Horizon Fuel Cell Technologies. It produces up to 25 watts of power from replaceable solid fuel cartridges and water. A single refueling can produce about 270 watt-hours of energy through the HydroPak's standard 110V AC power outlet and two auxiliary USB power jacks.

This electricity is expensive-- $20 for a … Read more

Unboxing OLPC's XO-1 laptop

I'm a little late to the party with this unboxing of my new OLPC XO-1 laptop, but the machine arrived while I was out of town visiting my family for Christmas. In fact, there's a story there.

Before I left, I started hearing that people were receiving their XO-1's, and I realized that if mine didn't show up before I left, it would almost certainly arrive while I was gone. The OLPC people sent out no shipment notifications and didn't reply to several emails, so I had no way to delay the shipment or contact … Read more

Unboxing Amazon's Kindle

I got my Kindle ebook reader from Amazon yesterday. It was very attractively packaged, and I've been looking for an excuse to do a traditional unboxing blog post, so here we go.

[Later update: my Kindle review is online now.]

When I opened the outer box the Kindle was shipped in, I found a second folded-cardboard sleeve inside protecting the product.

Inside that was the packaging for the product itself, a book-like box held shut by an elastic band around a post recessed into the "cover". This box would look reasonably attractive on a bookshelf, helping to reinforce Kindle's place in one's library.
