Will Internet Explorer 9 be any safer?

You can download the next generation of Internet Explorer 9, but I really don’t recommend it unless you’re an expert at both Windows and Web browsers. I qualify on both those grounds — What? You think I only work on Linux? — So I took a quick peek at this so not-ready for prime time Web browser.

I can tell you that it works on Windows 7 and Vista and that it does an OK job at rendering Web pages. But, as far as the rest goes, I really can’t say much. As Dean Hachamovich, Microsoft’s IE team’s general manager indicated the IE 9 Platform Preview isn’t even finished, never-mind polished.

But, we also know what Microsoft intends for IE 9 and that tells us something. Unfortunately, it doesn’t say a lot for any Internet Explorer security improvements. First, Microsoft says that IE 9 will not be available on Windows XP. That’s because, to quote a Microsoft public relations representative, “Internet Explorer 9 requires the modern graphics and security underpinnings that have come since 2001, and is intended to be run on a modern operating system in order to build on the latest hardware and operating system innovations.”

Linux on the Cloud: IBM, Novell & Red Hat

Today, March 16th, has been filled with Linux and cloud news. Which is great, I guess, if you’re ready to trust your data to the cloud.

In case you don’t follow Linux as closely as I do, here’s the round-up. Red Hat and Novell have joined up with IBM to provide a new open cloud environment that goes by the unwieldy name Smart Business Development and Test on the IBM Cloud.

Besides running Linux, this new cloud service comes ready for work with more software partners then you can shake a stick at. The bottom line is that I don’t care what capability you want from your server farm, chances are you’ll find it already ready to go on IBM’s new Linux-powered cloud from either IBM itself, which is offering its full Lotus and WebSphere lines, or from one of its ISV (independent software vendor) partners. These services are scheduled to be made available in the second quarter of 2010 in The United States and Canada, and to roll out globally by year’s end.

A Quick IE Fix

Last week, Microsoft got yet another security black eye when a new, ready-to-be exploited IE security hole was revealed. This week, Microsoft is trying to redeem itself with a pair of quick fixes for the problem.

The IE 6 and 7 security hole is a serious one and it’s already being exploited so you should head over to Microsoft support for one of the two fixes for this IE problem. No, you read that right. There are two separate fixes. Unfortunately, no matter which one you pick, they come with potential problems.

The first one disables the peer factory class in the Windows registry. ‘Peer factory’ is used by the iepeers.dll binary program in IE 6 and 7 on Windows XP and Windows Server 2003 to call some kinds of Windows functionality from within IE. The most common way it’s used is to print from IE. The downside of this fix, as you might guess, is that it will stop IE’s print functionality from working.

An iPad on your belt?

If the reaction to my Linux alternatives to the Apple iPad story is any indicator there are a lot of people who want an iPad. People also have some concerns about the iPad, such as how easy, or not, will it be to use this large hardbound sized tablet. I don’t see that as a big potential problem, but it looks to me like Apple is working on an answer for it anyway: the wearable iPad.

You see, Apple just hired a senior engineer to work on wearable computers. I can easily see people buying into a wearable iPad. You’d hook the computer on your belt, use an iPad Touch sized device for its interface and a Bluetooth-enabled eye and ear piece for sound and video. Ta-da. Instant Mac Borg!

Actually, I’m quite serious. The iPad is primarily an entertainment device requiring relatively little interaction from its user, so why not put it on your belt and use a wired or wireless connection to hook up an eye-piece and earphones to watch a movie as you go for a run?

Getting the most from 802.11n

Given a choice between fast, 802.11b; faster, 802.11g; and fastest, 802.11n, most people will pick the fastest every time. But, while the IEEE 802.11n Wi-Fi standard, with its up to 300Mbps burst speeds, is easily the fastest wireless networking protocol, until recently it’s never been a standard. Thus, a Wi-Fi access point (AP) using a draft 802.11n protocol from one vendor was unlikely to deliver its full potential speed to a laptop with an 802.11n chipset from another maker.

It wasn’t supposed to be that way. But, for years, the Wi-Fi hardware OEMs puppies fought over the 802.11n protocol like it was a chew toy. The result was that we’ve had to wait for over five-years before 802.11n finally became a real standard on September 11, 2009. The delay was never over the technology. The technical tricks that give 802.11n its 100Mbps to 140Mbps steady connection speeds have been well-known for years. The reason why is it’s only recently that we’re able to use 802.11n at its full potential.

So, you’re ready to go with just buying a new 802.11n AP right? Not so fast tiger. While it’s true that 802.11n can leave 802.11g at the starting line and even leave some older Ethernet routers eating its dust, it’s still all too possible to set it up so that you can’t get all the speed out of 802.11n you paid for.

CrossOver Linux 9: Run Windows apps without Windows

Some Linux users insist that anything you can do on Windows, you can do better on Linux. While there’s some truth to that, many of us have Windows applications that make completely leaving Windows close to impossible. That’s where CodeWeavers’ latest version of CrossOver Linux comes in.

CrossOver Linux 9 (code-named Snow Mallard) and its Mac brother, CrossOver Mac 9, let you run many popular Windows applications on Linux or Mac OS X. Supported Windows applications include Microsoft Office (from Office 97 to Office 2007), Internet Explorer 6 and 7, Outlook 2002 to 2007, all current versions of Quicken up to 2010 and QuickBooks up to 2004, and some versions of Photoshop and Photoshop CS. Based on my experience with CrossOver, which goes back more than a decade, I’d say this new version supports about 20% more applications (at a level that most users would find usable) than the last one.

CrossOver is based on the open-source project Wine, an implementation of the Windows API on top of the Unix/Linux operating system family. Wine is a mature project involving almost 17 years of work to get Windows applications to run on Unix and Linux systems.
