A Change of Switch · July 13, 2009

Fair warning: this is going to be a geeky post.

So, I realized a few weeks back that part of the reason my office/computer room was so hot was because of my switch. I have a really nice 24 port, managed gigabit switch, but it gets really hot. Probably ok for most applications where it’s in a rack in an adequately cooled data center or computer room, but this was like a little radiator for my home office. That and the heat from my home server were keeping that room at a pretty steady 80 or more degrees, even in the winter. I started looking for switches with a smaller number of ports, that were also managed, and were more efficient power-wise. After a lot of digging, I discovered the 3Com OfficeConnect Managed Gigabit Switch (3CDSG8). 3Com hasn’t advertised this switch very well, and it seems to be the only managed OfficeConnect switch of this configuration. Typically there would also be a 16 port version or something, but not so far with this one. It also had an issue out of the box, where after I changed the password it wouldn’t let me access the web interface, telling me I was giving it the wrong password. A factory reset and firmware upgrade fixed that, but it seems like an awfully simple and obvious bug to let slip through the cracks and into distribution. Anyway, it’s one of 3Com’s new “green” switches, that reduces power for shorter cable lengths, and turns off ports when they’re not in use. So far it’s much cooler than with the 24 port I had. This switch has a lot of other features that prove to be useful, but I’ll let their product details page do the marketing there. I have yet to put the Kill A Watt on it and experiment to see if the “green” functions actually do anything meaningful…

One of the cool things about a “managed” switch is that most of the time that means you can do, among other things, SNMP monitoring, which this switch also allows. This way you can see bandwidth usage on each port or VLAN, get alerts, and even control some functions of the switch if you know how to use SNMP tools. There are bandwidth graphing tools out there like MRTG, which are excellent but require a lot of advanced setup and network knowledge to implement correctly. However, Paessler has a really cool tool called PRTG Traffic Grapher, that is easy to setup and almost anyone can use. There’s a free version that gives you 10 sensors to use, which is 2 more than you need to use with this switch if you only want to see the traffic from each of the 8 ports. It’s a great way to see what’s happening on your network. Click on the link below to learn more.

As for the nice 24 port gigabit switch I replaced with the 3Com, it’s going to have to wait until I have a cool room or basement where I can put it in a rack with some breathing room.

A Farewell to 2008 · February 13, 2009

2008’s over, and it’s the middle of February 2009, but better late than never… 2008 was a rough year. On the 2nd of January my grandfather passed away, then in August my cousin was killed in an accident at work. I know of more people who passed away last year than in any other year I can remember. Maybe it’s part of getting older; the group of people I know is also getting older and some of them are starting to shuffle off, who knows… In that respect, 2009’s already off to a better start. 2008 is also when our current economic crisis was realized (notice how I say realized and not began).

2008 did have some shining momemts, however. It was the year that I started bonsai trees as a hobby, which is far more demanding than I’d ever imagined it to be but rewarding as well. I rekindled my enthusiasm for tennis and racquetball. And I started volunteering for ImageOut, which has been a great outlet for my desire to be involved with the community.

So what will 2009 hold? I’m still involved with ImageOut, and I’m actually on the board this year. The bonsai are in the middle of their first winter (under my care), so we’ll see how they fared when spring arrives. My racquetball and tennis games are both suffering because I keep switching back and forth between the two, refusing to believe that I have to choose one or the other. And hopefully I will meet more of my fitness goals this year than I did last year. Let’s hope that by the end of the year 2009 (or sooner) the economy will have stabilized, or at least have a direction, and we all still have jobs.

2008 ImageOut Film Festival · September 10, 2008

Since February of this year, I’ve been watching, voting on, and reviewing film submissions for the ImageOut Gay & Lesbian Film Festival. I’m a member of the Programming and Outreach volunteer committees. Hundreds of films are submitted each year for consideration for the festival, and they all need to be screened by the Programming group. Needless to say, I didn’t watch a lot of mainstream movies or read any books during that time! This was my first year as a volunteer for the festival. It has been very interesting to see the amount of work that goes into programming and coordinating the festival, and it has given me a greater appreciation for it.

The festival runs from October 10th through the 19th this year and includes 48 films or shorts programs. The lineup has finally been announced and the programs printed and posted online! Anyone interested in seeing the lineup, reading the film synopses and reviews, or just getting more information on the festival can go here.

The Programming committee members share the responsibility for doing the film write-ups that you’ll see online and in the program booklet. This year, I did the write-ups for Were The World Mine, Be Like Others, Tru Loved, and In Sickness And In Health. I would describe each of those films here, but with all the time I spent writing them up for the program, you can just follow the links and read them there. I encourage you to read the reviews of all of the movies and programs in the festival, not just mine; they’re all great!

There will be a Festival Fair at the Rochester Museum & Science Center on Monday, September 15th. Two films will be shown and this will be the first opportunity for people to purchase tickets for the festival. Programming committee members will be on hand to answer questions about any films.
