Online Service Lets Blind Surf The Internet From Any Computer, Anywhere

New software, called WebAnywhere, launched today lets blind and visually impaired people surf the Web on the go. The tool developed at the University of Washington turns screen-reading into an Internet service that reads aloud Web text on any computer with speakers or headphone connections.

"This is for situations where someone who’s blind can’t use their own computer but still wants access to the Internet. At a museum, at a library, at a public kiosk, at a friend’s house, at the airport," said Richard Ladner, a UW professor of computer science and engineering. The free program and both audio and video demonstrations are at http://webanywhere.cs.washington.edu. …

Free screen readers already exist, as do sophisticated commercial programs. But all must be installed on a machine before being used. This is the first accessibility tool hosted on the Web, meaning it doesn’t have to be downloaded onto a computer. It processes the text on an external server and then sends the audio file to play in the user’s Web browser.

"You don’t have to install new software. So even if you go to a heavily locked-down computer, say at a library, you can still use it," Bigham said.

About

ShadowExplorer allows you to browse the shadow copies created by the Windows® VistaTM Volume Shadow Copy Service. It’s especially thought for users of the home editions, who don’t have access to the shadow copies by default, but it’s also useful for users of the other editions.

Shadow Copy

From time to time, Windows® VistaTM creates point-in-time copies of your files. This allows you to retrieve older versions from files you accidentally deleted or altered. This service is turned on by default on all versions of Windows® VistaTM, but Microsoft grants access to these copies only in Ultimate, Business, and Enterprise editions. This is where ShadowExplorer comes into play. For more information on Shadow Copy, visit Microsofts website.

ShadowExplorer

Since the Volume Shadow Copy Service is included, and turned on by default, in all editions of Windows® VistaTM, why not take advantage of it? All it takes is an additional tool like ShadowExplorer, that can access the shadow storage and make the point-in-time copies accessible to the user.

UNM Today: Lobo-WiFi Debuts

Lobo-WiFi is on its way. Information Technology Services will begin to consolidate wireless network access next week by renaming the UNM_Wireless_Guest connection to Lobo-WiFi. The name change will feature additional services including secure e-mail.

Uniform access should be complete when students return for the Fall 2008 semester when all wireless network services will be available via the single Lobo-WiFi connection.

The wireless network continuous improvement project is in its second year. Many high-traffic common indoor and outdoor areas not previously covered by wireless network service now have coverage. High Priority areas - determined by student polling include areas such as the Duck Pond, Smith Plaza, Yale and Cornell malls, which were completed in June 2007.

When the wireless improvements project is completed in 2009, the main campus will have as complete coverage as possible with one uniform connection.

Improvements are being made in part by a donation from the New Mexico Educators Federal Credit Union.

More information is available at its.unm.edu/wireless.

Restoring from Vista’s Complete PC Backup
Thu 05/15/08 at 2:29 pm | In Ch 05 Backup, Restore, and Recovery | Be the first to comment on this | email Mark

The only thing worse than no backup is one you can’t actually use. Twenty years ago, a colleague called me with an emergency. He needed to restore files from a backup, but he didn’t have the software used to create that backup. Oops. A friend had a similar problem about ten years ago — no way to get at the backup she had. Oops.

Windows has long included a file backup program. With Vista, a disk backup program is included, as well. Complete PC is Vista’s tool for backing up, well, completely, as opposed to the data file backup performed with the separate file backup tool. If you have both, use them both. (I use LazyMirror for file backups. Vista’s file backup tool is less convenient.)

A full disk backup is useful in a disaster that requires everything be restored rather than just a few deleted or damaged files. Full disk backup is extreme insurance that you hope you’ll never need (baring theft or catastrophe).

Complete PC’s backup is "an image backup." Image backups duplicate the bytes on a disk, rather than copy files individually. With older image backup software, when you make a second backup, you make a second complete image — potentially a huge use of space. Vista’s Complete PC is better than this. In subsequent backups, it only backs up changed sectors, reducing the time and space required for most updates to the backup.

Image backups usually are not useful for restoring individual files. However, Vista’s Previous Versions tab (right-click a folder or file) includes backups made with Complete PC, as well as regular file backups and those made automatically by System Restore ("shadow copies"). This is a far-from-obvious improvement in Vista.

Recently, I attempted to install Vista’s 64-bit version on my desktop. I felt safe in that attempt because I had redundant backups. When I finally gave up on Vista 64, I expected to easily roll back to the 32-bit (x86) backup.

When you boot from the Vista setup DVD, you enter the Windows Recovery Environment (WRE), a reduced version of Vista that includes the setup program and various maintenance/recovery tools. One of these is Complete PC.

Curiously, I was not able to restore my 32-bit backup using the 64-bit version of Complete PC. To me, this is like saying one can’t use the 64-bit version of an application to open data files created with the 32-bit version or vice-versa. It’s data. Why would the 64-bit version fail to see that data? But it did fail.

So, I booted with the 32-bit installer. New problem: It wouldn’t restore the backup over the the 64-bit Windows setup. It’s not that Microsoft can’t foresee the need to rollback; they just don’t want to make it easy. I remember carefully hanging on to my DOS5 disk for years after I was through with DOS because it was the last version that would format disks set up by later versions.

All was not lost, even though, for a moment, it looked like my backup was unavailable for restoring no matter how I tried. Rather than give up, I began a clean installation of the 32-bit version. (I did not want to go through the full installation just to be able to restore.) Part-way into the clean setup, I used the available tool to format that 64-bit partition. Then, I backed out of the installation. Complete PC ran happily when offered a clean disk.

The moral of this story, beyond persistence, has always been to make sure you are able to restore files before you are *desperate* to restore files. Practice ahead of need. (And have more than one backup plan.)

peace,
mjh

PS: I worked as the tech editor on Windows Home Server, by Rick Hallihan. Windows Home Server has considerable potential for automatically and regularly backing up a few computers on a small network. Like any other tool, you need to understand how it works and to check up on it regularly. Don’t simply trust your backups.

PPS: I have collected a few different backup tools that might be good alternatives to LazyMirror. I’ll write about them eventually. LazyMirror works well, but it is tricky to configure.

Installing Microsoft Windows Vista 64-bit version
Wed 05/14/08 at 11:44 am | In Ch 03 Getting Windows Vista, Vista | Be the first to comment on this | email Mark

Recently, I decided to install the 64-bit version of Windows Vista. For over 25 years, I’ve been installing and reinstalling myriad versions of DOS and Windows. Prior to Vista, I routinely ‘clean-installed’ Windows at least once a year, reveling in that shiny, happy moment when Windows is uncluttered by the software I need to get anything done.

Note that I have not felt the need to reinstall Vista on my primary desktop machine since I installed the final version nearly a year and a half ago. That’s a testament to improvements in my setup, which is partly due to Vista and partly due to 2GB RAM and vast disk space. (In contrast, I have reinstalled at least once on my 1GB / 60GB laptop.)

My colleague and fellow New Mexican, Ed Bott, a geek’s geek, has written of the joys of 64. One barely needs to grasp the true differences between 32-bit (standard) and 64-bit to intuit the latter might be twice as good. While the truth may not be quite so linear, 64-bit Vista offers improved performance, stability and security, including access to more RAM (than I have). Designed for the latest processors, 64-bit is inevitable.

After a quick refresh and double-check of my redundant backups, I booted from the Vista 64 DVD. Over all, the installation process is identical for the two versions (32 & 64). However, my first problem arose when the installer reported it could not find a suitable destination. Strangely, the screen displayed the drive I wanted to use plus my external USB drives. Though there was nothing displayed to help me, those USB drives were the problem. I understand they might be unsuitable for booting (though my desktop’s BIOS supports USB booting). I’m shocked that (a) they prevented the installer from allowing the one suitable drive and (b) there wasn’t a clue about this.

Eventually, I shut off my 3 external drive (1.75TB) and rebooted to the DVD. This time, the main drive was acceptable. Vista’s setup doesn’t require any interaction after the first few screens for 30-60 minutes.

I returned to find a boot options screen offering Safe Mode or normal start — an unexpected, bad sign. Because this screen happily boots normally after 30 seconds, I imagine this had come up many, many times before I returned.

I started normally and completed the setup process (name, icon, background image, computer name). I proceeded to Problem Reports and Solutions, which told me of a couple of new drivers. One was for one of my personal video recorders (USB). The other was an IBM program that was far from self-explanatory — did I want this or not? (I installed it and later uninstalled it. I still don’t know what it was for.)

Next, I tried Windows Update, curious what would show given that this installation includes Service Pack 1. Hmmm. Update would not run. Understand: Nothing happened no matter how I tried to initiate Update. Moving right along, I looked at Network and Sharing Settings and saw the first of several things I’ve never seen before: Access Denied, in the middle of the normally helpful dialog. Oddly, I had Internet service, I just wasn’t allowed to know anything or do anything about it.

Somewhere in this Looking Glass moment, I got the first of many, many perplexing error messages. One oddity of these messages was that the look, size, shape and position of the dialog box varied, though all looked rather last-century, as if each iteration was hand-crafted by a student failing Programming 101. Another oddity was that each consistently included a reference to d: and a folder named "rtm" (release to manufacture). D: would be the empty DVD drive; ‘rtm’ seems rather out-dated. Many different actions triggered many variations on this error. None of the messages was the least bit helpful, though I read their tea leaves and carried their entrails to the alter of Google, like a worthy supplicant.

Eventually, I enabled the normally disabled Administrator account and logged in as god. Windows Update and Network and Sharing Settings worked normally — yeah! But the same mystery messages kicked in.

The Update and other limited functioning was resolved by deleting my personal user account and recreating it. No doubt, that infinite boot-loop contributed to some corruption of my account. Still, as Administrator or me, I was haunted by these *ridiculous* messages.

[How many differences can you find?]

Hoping that the problems I ignore will fix themselves (it’s my approach to life — don’t ask how that’s going), I went about feathering my nest, beginning with the Sidebar. The Sidebar crashed. Honestly, that’s not so unusual in Vista, but this crash was awesome. It began when I tried to add the built-in calendar gadget. Crash! From that point forward, every time I restarted, the Sidebar crashed immediately. Worse, though Sidebar crashed, it remained in memory and quickly revved up nearly 100% CPU activity, like a coma victim running a marathon. The catch was that I could not remove the gadget before each crash. Eventually, I had to delete the calendar gadget from the Sidebar folder and manually tweak the Sidebar INI file. (Oh for the days of INI files — often inscrutable, but so easily hackable.) Mission accomplished.

Odds favored a driver problem and, most likely, a video driver problem. Let me say here that even before this trouble, I have been extremely disappointed with nVidia, on many levels. nVidia’s website is not very friendly. nVidia’s naming convention for drivers is bizarre, based on the final 4 digits of a long version number, not the first few. This makes difficult deciding which of two drivers is newer. While nVidia has released many updates to their drivers in the last year and a half, I sense they still don’t have it right. (I’m also specifically disappointed by the card, GS7600, because of the horribly clumsy way it handles output to a TV. I cannot use my two monitors and my TV, even though there are 3 connections — and my pre-Vista setup handled that. To use the TV, I have to disable the secondary monitor, which nVidia’s ornate and otherwise useless control panel makes easy. That scrambles my carefully arranged screen setup.)

For quite some time, I tried various drivers, some direct from nVidia, some Microsoft’s (presumably from nVidia itself). By this time, I had settled on an easy way to trigger the weird messages: Try to use the Photos screen saver. [Insert Vista error sound.] Always the same, with every driver.

[How many differences can you find?]

What I’ve described here sounds like a few bad hours, but this spread out over most of a week and included at least one more clean install and lots of trial and error, error, error. It is not easy for me to quit in such situations. My thoroughness coupled with optimism traps me. "This time will be different," and, I think, even if it isn’t better, the differences will help me figure this out.

In the end, defeated, I had to roll back a week’s wasted time to the previous version. That ordeal deserves its own blog entry.

The Stats Are In: You’re Just Skimming This Article - ReadWriteWeb

Earlier this this year, we commented on the infamous Steve Jobs quote "…the fact is people don’t read anymore," arguing that, people do read, they just prefer to do it online. However, in this transition from page to screen, a question has risen: are people really reading online content or just scanning page? Apparently, it’s the latter.

The Research on Web Reading

Jakob Nielson, web usability consultant, author, and owner of useit.com, writes on his site about a recent research study by Harald Weinreich, Hartmut Obendorf, Eelco Herder, and Matthias Mayer: "Not Quite the Average: An Empirical Study of Web Use."

What Nielson found by analyzing the data in the study was that although people spend more time on pages with more words and more information, they only spend 4.4 seconds more for each additional 100 words. By calculating reading rates, he concluded that when you add more verbiage to a page, people will only read 18% of it.

Some other interesting findings include:

  • On an average visit, users read half the information only on those pages with 111 words or less.
  • People spend some of their time understanding the page layout and navigation features, as well as looking at the images. People don’t read during every single second of a page visit.
  • On average, users will have time to read 28% of the words if they devote all of their time to reading. More realistically, users will read about 20% of the text on the average page

DOS Lives!
Tue 05/06/08 at 4:32 pm | In Windows | Be the first to comment on this | email Mark

This afternoon, I used a DOS command I learned 25 years ago. Merri wanted to print a list of filenames in a folder. I know of no easy way to do this in Windows *XP*. Granted, there are programs one can install, including one of the cool Microsoft PowerToys. But nothing native to Windows *XP*. So, I opened a command prompt and cd’d my way into the folder (the Tab key makes this easier than it ever was in DOS). I then ran this good old command: dir /on > filenames.txt. Directory listing ordered by name, redirect output to the named text file.

By the way, there is a Vista trick to list filenames (as complete paths — not exactly the same as above, which also works in Vista). Select any or all files. Hold down the Shift key as you right click over a selected file. Use "Copy as path." Paste into Notepad. Not obvious nor the best reason to get Vista, but a step up from the XP so many cling to. peace, mjh
