Is IE8 really fat and slow?

Since IE8 shipped last week, I've read two criticisms repeatedly: One is the burning question of whether IE8 is faster or slower than its competitors; the other is whether it makes reasonable use of system resources. In this post, I explain why some people are seeing performance issues (and share an obscure system tweak that might just cure IE8 performance and stability problems). I also take a closer look at why you might prefer a browser that uses more memory than others.

Opera Mini serves up 1 petabyte of data in January 2009

Even though I have mobile phones with powerful web browsers, such as the G1 browser and S60 browser, I still go back to using Opera Mini the majority of the time. I like that I can login to my Opera Link account and have the same bookmarks on every device I use with no real effort on my part. I also find the speed to be excellent and the shortcuts and viewability to be extremely useful and attractive. On my G1 I can cache data to the storage card while the integrated browser consumes all of my onboard memory. Opera just released their latest State of the Mobile Web report for January 2009. Usage of Opera Mini went up 12.2% to 20 million unique users.

Opera Mini 4.2 for Android brings microSD support and video viewing capability

As I pointed out in a recent post regarding the current firmware on the T-Mobile G1 Google Android device there is a major issue with not being able to store applications or content onto the external microSD card. I get low memory errors daily and if I browse a lot with the device my browser cache fills up to 10MB+. Then when I delete the data I lose all my history, bookmarks, etc. and this really limits my usage of the G1. Opera thankfully announced today that its Opera Mini 4.2 product for the Android platform is out of beta already and available as a full release in the Android Market.

Alarmed about Vista security? Black Hat researcher Alexander Sotirov speaks out

Earlier today I published a lengthy blog post questioning some of the sensationalist conclusions raised in press coverage of a paper presented by Alexander Sotirov and Mark Dowd at last week’s Black Hat Conference in Las Vegas. This afternoon, I received an e-mail from Sotirov, who says he was "horrified by the lack of understanding displayed by the tech press when they covered the paper." He agreed to a follow-up interview, in which we discussed Microsoft's reaction to their research, how Windows users should respond to this news, and how they conducted field research into whether girls really are impressed by browser memory protection bypasses.

IT Dojo: Control users' temporary Internet files and browser history

In this IT Dojo video, Bill Detwiler shows you a simple monitoring solution that uses Windows Server 2003 Group Policy.Before watching the video, you should realize this tip isn't right for every situation. This method uses Windows XP and Internet Explorer's local browsing history. To view the history files, you must physically visit each machine, remotely access the machine, or copy the files to a network location with a script. Furthermore, a sophisticated end-user could easily navigate to and delete the browser history. This monitoring technique is best suited when monitoring a small number of users, or better yet, a single, problem user.

IT Dojo: Disable USB storage under OS X or Windows

Hollywood would have IT pros believe that the biggest threat to network security comes from international super hackers or high school kids trying to download games like global thermonuclear war. In reality, we face a more mundane threat--our end users, particularly those wielding USB storage devices.These pocket-sized devices can store a large amount of data. But even if your users aren't planning to cart off sensitive company files, USB storage devices (external hard drives, camera, memory stick, MP3 players, etc.) can be a headache in other ways. Employees may use your networks to download music to their USB-based MP3 players. New USB flash drives, such as SanDisk's U3 smart drives, can even run software directly from the device--a perfect tool for the end-user who wants to run unauthorized software on your network.If your concerned about USB storage devices on your network and don’t feel a written policy alone will protect your data, disabling the devices is your next step.In this IT Dojo video, Bill Detwiler, TechRepublic's Head Technology Editor, shows you how to disable USB storage devices on both Apple OS X and Windows. The United States National Security Agency (NSA) described the process in a March 2008 document from the agency's Information Assurance Directorate.Once you've watched this IT Dojo video, you can read the original TechRepublic article, download PDF version of this tip, and learn more about mitigating the risks poses by USB storage devices from our IT Dojo blog.
