A while back I wrote up my personal network build. Recently I swapped out the SSG5 that I had on loan for a cheaply available 5gt. The 5gt went EOL last year, but it’s a pretty reasonable box. I had an interesting time figuring out the quirks of the 5gt, and I now have some [...]

Juniper SRX 100 cheap Junos box, will it be great?

21 November, 2009 (23:23) | Uncategorized | 2 comments

Juniper has produced an interesting niche product for a while now. The entry level firewall has been the Netscreen SSG5 for a while, but with their new line of boxes based on JunOS instead of ScreenOS, things are getting interesting again. I just mentioned that I picked up an older 5gt for my home network, [...]

Netscreen 5gt: best home firewall for the money?

9 November, 2009 (11:07) | Uncategorized | 3 comments

I have a habit of using better than average hardware for my home network. In truth, I prefer near enterprise class if possible. The Netscreen 5gt is the precursor to the current Netscreen SSG5. The SSG5 is a great box, 120MB throuput, 6 interfaces, multiple virtual routers, etc. The 5gt went end of sale on [...]

Every so often I spend some time with a pad of paper and draw out something I need to build. In this case, I need to make drawers and a door for my espresso bar. I found a handy little program (it could use some polish, but it does the job) for calculating the layout [...]

I had quite a few comments looking for Henrik afterI posted a pic of his bike. A short while after I put it up, I found it in the how-to section at It’s hidden on the second page under ‘fitting a triumph fork‘. This was especially hepful to me as I’ve been plotting to [...]

Portafilter seal replacement tricks

4 October, 2009 (10:54) | Uncategorized | 1 comment

I did a little maintenance on my ECM Giotto espresso machine today. My portafilter seal had started leaking recently, so it was a good time to do it. A well used machine will typically need the portafilter seal replaced every six months or so. If you stretch it, it may be a couple of years, [...]
