An Awesome Alternative to a Traditional Mouse

Thu, 25 Feb 2010 09:30:00 -0700

Like most of you, I sit in front of a computer for a large part of my day. Over time, sitting and working on the computer has caused me varying physical issues, like back, wrist, and elbow pain. To alleviate this, I bought a desk with an adjustable height, an ergonomic keyboard, and an Aeron chair. These have helped greatly. But the one issue that kept coming back was wrist pain. I tried several types of mice, with varying shapes, but none of them dealt completely with the issue. For me, a big part of the discomfort in my hand and elbow came from constantly reaching over for the mouse, as well as gripping it. It might sound silly to some, but when you do this thousands of times, it adds up! Then, about six months ago, I found a blurb about the RollerMouse Free on some tech site. Having used it daily for a while, I can say that this mouse is an excellent option to a traditional mouse. The RollerMouse sits directly under your keyboard, just past the space bar. To control the cursor, you roll a bar up, down, and side to side. It sounds bizarre, but it works very nicely and was easy to get used to. The bar moves very smoothly, and is very accurate. You can easily move it with your thumbs, and you barely have to move your hands off the keyboard, or you can use your fingertips. Either way, it's far better than reaching over for a normal mouse. I still keep a regular mouse as well, but I use it pretty infrequently (except for gaming!). This odd new RollerMouse is the workhorse now. I just wanted to mention this device in case anyone else has similar problems and was frustrated trying to solve them. I was uncertain about how this thing would work out, but it really does work well. There's a video at the product web site which shows how it works in more detail, if you're interested to see it in action.

Upgrading from Vista to Windows 7 (And How to Deal with Warnings about iTunes)

Fri, 23 Oct 2009 11:43:00 -0700

Last night I crossed my fingers and upgraded my Vista Professional workstation to Windows 7 Ultimate. I have multiple backups, including Mozy, Windows Backup every night, and a Windows Complete PC Backup (essentially a disk image) every week. As a result, I was very confident that even if all hell broke loose I could restore things quickly. Happily, the upgrade went smoothly and Windows 7 is running great. All of my programs and settings were migrated perfectly. The upgrade compatibility analysis at the beginning highlighted two potential problems that I dealt with. First, I run two ATI Radeon 4850 video cards to power my three monitors for work, but I enable CrossfireX when gaming, which disables the two outer monitors and puts all the GPU power into the center screen. Windows 7 warned me that my ATI drivers might be a problem after the upgrade. So I simply uninstalled the existing ATI drivers, ran the upgrade, and the installed the Windows 7 64-bit ATI Catalyst drivers after the upgrade. Everything works fine. The other item flagged was iTunes. I did some research, and it turns out that Apple appears to be using an older and/or unsigned GEAR driver in iTunes. This has to do with CD/DVD recording/burning. I'm not sure why they would do this, but there is an updated driver available at the GEAR Software site. I installed that update and then proceeded with the Windows upgrade, and everything works fine after the update finishes. So if you're getting this warning and want to be sure it won't mess anything up afterwards, I'd install the updated driver. Overall, Windows 7 is very nice. It looks better than Vista and has many new features like the taskbar, improved Explorer interface, better window management, etc. I'd been using Vista for about 10 months and unlike most people I never had any real issues with it, it worked just fine with no crashes or problems. Even so, the new Windows is definitely an improvement as things seem snappier, and the enhancements are welcome. So as long as your backups are up-to-date and you look over any upgrade warnings carefully, I'd definitely recommend installing it. Hopefully this entry might help others who see these types of warnings, especially the iTunes one.

My Take on Mac vs. PC

Wed, 13 Aug 2008 12:17:00 -0700

At Broadchoice, everyone uses a Mac. Except me. In fact, it seems like just about everyone in the programming world is jumping onto the Mac bandwagon. Which is fine, I say use whatever you think works best for you. However, that's usually not good enough. When I tell someone I work on an XP box, the floodgates of hate open! Well, not really HATE, but people sure are happy to let you know what they think of Windows and why Macs are so utterly superior. And I've got to tell you, it makes me feel like this:

It can be downright depressing being a "poor PC guy"! It might be blasphemy in this day and age, but I like my PC. It runs just fine. It never crashes. I've got everything set up on it just how I want it, and I'm talking about a lot of stuff: games, development tools, servers (ColdFusion, JBoss, etc.), databases, and all the rest. I don't really want to have to go through all that effort again just to say I'm working off a Mac. Plus, not to brag, but my PC is a monster. 500 GB RAID 0, 4 GB RAM, 4 GHz dual-core Athlon 64, dual GeForce 8600's. And for display:

Yes, that is three 19 inch LCDs. And I use them all, all of the time. I know the Mac has Spaces but its not the same thing. I can actually see everything instead of having to switch to different spaces. I know that I am completely spoiled by this setup but it results in very high productivity for me. Now compare that to the admittedly very nice Macbook Pro that Broadchoice set me up with:

Yes, it's very nice. Yes, I like OS X. I have nothing against Macs, it's just not my preference. I have this set up with my basic tools and applications. I use it when I'm traveling or presenting, or whenever I'm not at my desk. But surely it wouldn't surprise anyone that I would prefer to work on my very well-appointed PC workstation than on this 15" Macbook. So please Mac folks, stop giving people the third degree just because they are actually fine working on a PC! I get it, you love your Macs. But seriously, the attitude is starting to go from enthusiastic to arrogant and overbearing. So I'll open the floodgates to see what the Mac folks have to say, as well as to see if there are any other PC users who feel like they are supposed to be ashamed of daring to use a Windows-based system.

Review of the Amazon Kindle Wireless Reading Device

Wed, 21 May 2008 11:10:37 -0700

I recently bought an Amazon Kindle and thought I would share my thoughts on it. Before someone drops $400 on something, they usually want to know if it's worth it.

Overall, the Kindle is amazing. The text is completely clear and readable. I quickly forget that I am looking at a screen at all. The technology draws no power to keep text on the screen, it only uses juice to refresh the screen. There is no "burn in": if you put it down and pick it up two weeks later, you're still fine, and it used no power to keep the screen that way the whole time.

The device uses Sprint's EVDO 3G network to connect to Amazon and let you download the books that you buy. They download in under 30 seconds. The device has enough memory to store a ridiculous number of books, and if you want to drop $20 for a 4 Gb SD card, you basically go to unlimited storage space.

The books are generally 30-50% less than the printed versions. For about $100 so far, I have the entire H.P. Lovecraft library (of course), 1984, The Singularity is Near, Patterns of Enterprise Application Architecture, Implementation Patterns, Agile Java Development with Spring, Hibernate and Eclipse, and more.

Further, you can email yourself documents to a special Kindle email address for automatic conversion and downloading to your Kindle. The address only accepts mail for addresses you specify to avoid any spam. The conversion costs 10 cents, and it even works with PDFs, though the PDF conversion is still labeled "experimental" and the results are not perfect. Even so, I emailed the entire Flex 3 Developers Guide, the Flex 3 ActionScript Guide, and other big PDFs to myself and now have a vast set of things to read at any time.

The real hidden power of the Kindle, though, is it's built-in cellular connection. In addition to letting you get to the Amazon Kindle store, it includes a basic web browser. You can see where this is going already. Because you don't pay for any of your wireless usage (it is just included with the cost of the device) and don't have any sort of account with Sprint, this high-speed internet access is really, really kick ass. The browser works best for text-based sites, so hitting things that are optimized for cell phones is preferred. You can go to any site you want, but the layout can be screwy for "wide" sites with complex layout or graphics.

Even still, this opens up a gigantic range of options. I've been using Google Mobile, including Google Reader for all my RSS and blog needs, GMail, Wikipedia, Google Maps, and more. They all work very well, which basically makes the Kindle a free portable internet reader as well. And this is arguably as big a deal as the Kindle's book reading capabilities. Between the net access, PDF reading, and Kindle bookstore, I have an unlimited store of interesting things to read, any time, anywhere.

The device is easy to use. It is very light. Which makes reading tech books that are normally big and bulky much nicer. You can change font sizes any time. It has a built-in search which lets you search for anything across your whole library. And it has inline lookup against dictionaries and Wikipedia if you're reading something and want a definition or more information on something.

If there are any drawback to the Kindle, it is with the design of it. First, it's not very cool looking. This was not made by Apple. I mean, it's not horribly ugly, it's just meh. The other issue is that it will take you a few minutes to get used to holding it. The sides of the device have "next page" and "previous page" buttons to let you "turn pages", which means you have to be careful about how you hold it to avoid accidentally turning the page. Clearly, this is a pretty minor deal, since you will quickly figure this out, and if you do flip the page you can just go back again. It just means figuring out how to hold the Kindle comfortably will take you a minute or two. Yes, these are about the only two "drawbacks" I could come up with.

Overall I'd recommend this thing to any serious reader. $400 sounds like a lot, and I guess it is, but it is a pretty amazing piece of technology, and when you factor in the unlimited 3G net access the price quickly becomes a lot more justifiable. Since anyone reading this blog is probably already a pretty hard core reader, just set aside some money and buy one. I'd wager you'll love it too.

Want Free Subversion, Trac, Mylyn, and More? Of course you do.

Tue, 22 Apr 2008 08:52:00 -0700

If the idea of 500 Mb of free Subversion, Trac (with XML-RPC access for things like Mylyn), Wiki, and a whole lot more sounds like a good thing to you, check out Assembla.com. I signed up last night and am really quite floored.

This thing has virtually everything one could want in a project management, source code, ticket tracking, and team collaboration setup. And again, it's free for up to 500 Mb of stuff. And after that it is a paltry $12.50 per month for 5 Gb of storage, plus a few extras like https access.

I've been hosting my own SVN locally but have increasingly been thinking about moving it to an external service so that I can get to it from anywhere. This seals the deal. So far, Assembla has been very impressive, and if it keeps up, I'll be springing for the $12 commercial account and be done with it.

Have a look if you have been thinking about jumping on the Subversion or Trac bandwagon but don't have the time or inclination to set up your own server. And if anyone else has been using Assembla, please share! Thanks.

ColdFusion Community Toolbar

Fri, 19 Jan 2007 11:39:00 -0700

Hey just a quick note about the ColdFusion Community Toolbar that I saw mentioned on Ben Nadel's Blog. It's a browser toolbar plugin, and it's pretty slick! It has a CF-specific search to let you search the documentation. It has pull-down tabs for Community (latest CF-Talk posts, latest CFDJ articles, etc.), Blogs (latest MXNA, FullAsAGoog, etc.), Markup and CSS validators, CF Job Postings, and an integrated mp3 player that has all the CF-related podcasts. I must say it's very nicely done! Kudos to Fusion Authority and Epicenter for building this.

Carbonite Backup

Mon, 14 Aug 2006 12:59:00 -0700

Just a quick entry here to mention a very nice backup tool called Carbonite. Unfortunately, it currently only runs on Windows XP, but if you run XP it is very handy. It runs in your system tray and lets you back up anything on your hard drive to their storage servers using your high-speed internet connection. I'm a bit of a backup junkie because I've been through the pain of losing all your data (or music or whatever) and it really, really sucks. Bad. I run backups to an external hard drive, but this wouldn't save me in the event of a fire or burglary. Carbonite encrypts everything and stores it off site, and they give you unlimited space. The best part is, it's only $50 a year. That is $4 month for unlimited, secure, offsite backups of your critical data. Which is a really good deal in my humble opinion. Anyone out there tried Carbonite? What do you think of it? And in general, do you run backups? If so, what is your approach?
