Messaging is easy, but Enterprise Calendaring is hard. I’ve just learned about the guys over at SOGo who have a GPL/LGPL competitor to Zimbra and MS-Exchange. Sure, you pay for support, but using the server software doesn’t cost anything.

• If you want to connect MS-Outlook clients, that’s fine.
• If you want to connect smart-phones, that’s fine.
• Thunderbird seems to be their main integration client, which is nice. That’s what I use.

Anyway, go take a look.

I’ve just pulled the VM appliance VMDK down and will be playing with it on ESXi in the next few weeks. They claim it was setup for VirtualBox, but I’d rather not run this sort of thing on that VM technology. This could be perfect timing for my company – we have been planning a Zimbra upgrade and honestly, it scares me.

There are lots of search hits on SOGo on freshmeat.net – that’s encouraging to me.

Check back here later. If SOGo is great, I’ll certainly write more. If it is crap, it will be in the comments below.

This could be good, really good. I’m hopeful.

Tips consolidated from these posts.

Below are tips to get the most printing out of an inexpensive Brother laser printer, beyond what the default setup would provide. Users are reporting 500-1000 extra pages out of toner cartridges with these tips. I haven’t used the printer yet.

So, is was announced on Slashdot and Gawker that much of the Gawker user-password DB has been compromised. They claim to have grabbed 1.3 million user accounts. I’ve seen that my account, password (encrypted-hash) and email address were included in the breach.

Last night I did a little presentation on Using VirtualBox on a Desktop. I’d give myself a D+ for a grade on the presentation. Fortunately, it was a small and highly interactive crowd. I tried to cover too much stuff. Also, I showed how to do this on a Windows host OS with a Linux client OS to a Linux-specific crowd. Initially, I’d planned to show an install on a Linux host OS too. The physical machine had a really slow disk controller, so I wasn’t able to create a virtual disk to install the OS into. I tried it a few weeks ago on the test machine and it took 45 minutes to create a 10GB .VDI file. On my home machines, doing this is just a few minutes.

The good thing was that I covered some of the key performance choices in virtualization – multiple times. The good news is that the newer VirtualBox releases choose most of these settings automatically. I should probably create a blog entry for each of the different client OSes that covers performance choices. Anyway …

Last week, I visited some relatives. Their computer running MS-WindowsXP had at least 1 rootkit installed and a number of viruses and spywares. This machine was running Firefox with NoScript (disabled) and Thunderbird for email. The main user is not very technical, but uses Firefox, Thunderbird, Quicken, and Investor’s Toolkit most days. I knew that solving the issue on Windows was going to be a problem again and again.

Linux to the rescue.

This article is extremely out of date and probably not very useful for steps to get quicken working on current Linux releases.

For many people, Quicken is the program that prevents them from switching to Linux 100%. This week, I finally took the time to install Quicken 2011 Premium under Linux Lubuntu 10.04 LTS and get it working very nicely.

Below are the steps and comments for how to accomplish this. I did reference the WINE-HQ Quicken App Instructions to make it work, but some of those steps were less than clear to me. WINE is Wine Is Not an Emulator.

I’d bet these steps will work for older Quicken versions too. I’ll test it with Quicken Home & Business 2008 in a few days, but expect it will work just fine for the things I do, which are fairly extensive.

I shouldn’t have been surprised that Quicken would work under WINE, heck Microsoft Office 2003 works too (except Outlook).

Every year or so, it is a good idea to check the WiFi networks around your home to see if your neighbors have decided to setup their WiFi on top of yours. Often, these wizard setups just pick a channel and use it without any regard for how many other access points are already on that channel or whether a channel overlaps others in use. In any WiFi location, having more than 1 access point on a channel - or even the nearby channels of the radio spectrum will reduce your bandwidth and will probably lead to dropped connections.

In the USA, there are 11 channels for 802.11b and 802.11g wireless networks to use. However, only 3 of those channels do not overlap, 1, 6, and 11. That means choosing any channel besides one of those three is to be avoided. In my neighborhood of single family homes with USA average sized lawns, I see 9 WiFi networks from my home office, one of them is mine. Here is a table created by a wireless router Wireless Site Survey function:

This morning, I was going through the normal RSS feeds that I read daily. Slashdot.org is in the top 5 reads.

As I write this there is an article titled Dell Knew About Computer Failures in the RSS feed. Clicking on it initially took me to a page with that title, but no content.

CrossChris writes " Freedom of information’ has revealed details of a lawsuit against Dell where they admit that they knew about a high failure rate of their products, but hid it from their corporate customers! From the article: ‘…Dell apparently encouraged its salespeople and technicians to not let customers know about known defects, and said internally that most customers (those who had not bought more than 50 machines) would be subject to “fix on fail”—that is, the company would only help them when their machines broke down. An internal presentation on the Optiplex GX and SX270 acknowledges that the company had discovered “quality issues,” but that employees should not proactively bring them to customers’ attention.’"

I read about this story yesterday on anther web site, so seeing it removed from /. is concerning. OTOH, I bet Dell is a major advertiser on /. so having the story removed would be a smart moved to retain those revenues. I don’t know that the article was removed – it could just be a publishing glitch or some other technical issue.

There is a /. discussion page related to the article still with a few comments.

A quick search of Dell on slashdot shows they haven’t pulled too many negative stories previously.

Arstechnica didn’t pull their version of the story.

My interest is mainly from a laptop that died a few weeks after the warranty ended. Dell Support was completely useless.

I was reviewing the web site statistics today and noticed that 63.7% of my visitors have java enabled. Java, not JavaScript.

ARE YOU CRAZY?

Having Java enabled in a browser by default seems crazy to me. There are not that many websites that need Java in a browser to run Applets, but if you run NoScript, then you can specify which websites can run Java Applets and all others cannot. If I had java enabled in a browser – which I do not – I’d definitely selectively enable it for specific web sites only.

Above are my real NoScript settings in Firefox 3.6.12 running on Lubuntu Linux 10.04.

I do understand that if you are visiting this site from work, you may not have the option to disable Java selectively.

From a security perspective, disabling all the extra plugins should increase security. Having them enabled by default is just a bad idea. These are my opinions. Computer security is one of those things where everyone thinks they are secure … until they are hacked. Then it is too late.

If you don’t use Java, turn it off by disabling the plugin. If you do use Java, please use NoScript to be selective where you allow it to run.

Of course, if you have Java applications and need to run on your desktop, please remember to stay patched. There was an important security update for Java earlier this week and there have been a number of important patches for Java the last few months.

We all get computer viruses, eventually. There is nothing anyone can do, but whether it is a small inconvenience or a major computer-doesn’t-work-for-weeks issue is up to you.

It doesn’t matter which operating system you have. Viruses have been written for it. It is true that since 92% of all computers in the world run MS-Windows, that platform is the main target, but Apple’s OSX, Linux, Solaris, AIX, iPhones, iPads, Blackberries, Android, Windows7 Phones are all targets too. If it runs with a computer, then it can have a virus. Those electronic picture frames have carried viruses.

Below, I outline the steps to recover from a virus infection or worse.
