Strapping Young Lad
… Went to go see a killer band — Strapping Young Lad — last night at The Pound, a little metal club out in Dogpatch/Hunter’s Point/Bayview/whatever it’s called nowadays. I haven’t been to a clubin years…Lots of metal twenty-somethings, a mosh pit, a surprising amount of thirty-somethings, and lots of blonde hair.
It was an amazing loud powerful show. Devin was right on last night, the vocals were incredible, and the band was very tight. The crowd was very into it – it’s amazing looking out at the crowd and realizing that everyone is singing along to the songs.
I took 4 rolls of film with my Lomo, we’ll see how they came out.
I forgot my ID at home, and so I had to show my Costco card to get the tickets from Will Call – it was the only photo ID I had. When I told the
bouncer putting on drink bracelets that I didn’t have my ID, he leaned over in my ear and yelled over the music,”WHO PLAYED THE BEAVER?”
I yelled back, “JERRY MATHERS!” “NO 20 YEAR OLD WOULD KNOW THAT — HAVE A GREAT TIME!”
I got my drink ticket.

Jazz Cameras
I bought another Jazz 101 today, and I thought about how fun my toy camera phase last summer was. I’d just discovered www.lomo.org and rediscovered photography after a long dormant period. Most of the pictures I took that summer were taken with a $30 Ebay Olympus XA 2, a Jazz Jelly, Jazz 101, or Lomo Smena and $.99 Fuji film. Somehow, it seemed more fun.
I think I need to hang up the SLR for a while and go back to shooting with a Lomo. Or fix the sliding door on my XA 2.

What’s wrong with Lomography?
Here’s two interesting pages regarding Lomos and why some people don’t like “Lomography” — http://home.planet.nl/~ucklomp/lomography/index.htm and http://homepage.mac.com/mattdenton/photo/cameras/olympus_xa.html
I have to agree with them – I love the Lomo LC-A, but I dislike lomography – it seems way too marketed and commercial. People carried pocket cameras with them a long time before the Lomographic Society decided to pretend that they invented street photography.
There are a lot of independent sites and resources for Lomos that I like (The GO LOMO and Action LOMO web rings being two of them) but the lomo.com site always seemed a little too contrived.
They even publish “Rules of Lomography” – luckily the last rule is “ignore the rules”.
The number of new users on www.lomo.org who ask if it’s possible to take LOMOpix with other cameras, and who ask if they need to use LOMO film to take LOMOpix tells me that the marketing blitz is working.
All criticism aside of the lomographic Society, the LOMO LC-A is an amazing little camera. It’s very simple – there’s no auto-focus and no motor film advance. To shoot, you open the lens cover, set the focus according to a zone focusing scale (one head/two heads/family/building) corresponding to 8 meters, 1.5 meters, 3 meters or infinity. Point, shoot, and advance. That’s it. The shutter can stay open an amazingly long time, so you’ll never get an underexposed picture with the LOMO. Blurry, maybe, but never underexposed. It fits nicely in your hand, and is the perfect stree-shooter – no flash, motor advance noise to give you away, no auto-focus to fail – just set the focus to 3m and shoot.
There’s something about the feel of these cameras – they feel *solid* (although they aren’t any less breakable than other cameras) and all of the controls are easy to reach when shooting one-handed or traditionally. I’ve tried a bunch of cameras, but keep going back to the LOMO for street shooting, creative shooting, and most everything except portraits.

LOMO Smena-35 Manual
I just scanned in the manual for my little Russian plastic piece-o-crap camera, the Lomo Smena-35. I’ve put the HTML-ized version of the manual up at http://www.kataan.org/smena/index.html . Gotta love the cold-war Soviet Union-era manual:
The Smena-35 camera is safe for health, life, and property of the consumer and environment as confirmed in declaration # 012/001 dated March 30, 1993 claiming compliance with State standards…

Home firewalls
I’ve been running on the SMC Barricade for about a week now, and like it. If you’re looking for a firewall appliance, $100 gets you a 4-port switch, NAT firewall, and print server. Setting up printing between Linux and Windows has traditionally been a pain; the SMC acts as an LPR-type print server, so setting up print sharing between my Windows 2000 box and Linux was simple.
I’m evaluating an interesting product in my lab, the E-smith mail server/gateway. It’s a stripped-down version of Red Hat Linux with NAT, IPCHAINS, POP/IMAP/SMTP email servers, a webmail interface, WWW server, and FTP server. It’s all administerable from a web browser. They have an evaluation version available at their web site, which looks to be a free for non-commercial use license. I’m a little leery of using older computers as firewalls, since they’re more susceptible to hardware failure. E-Smith looks to have a feature where you can back up all of the data relatively quickly. Since it’s a turnkey install, if you have a hard disk failure, you could replace the hard disk, do a fresh install, then upload all of your data back in to it.
The lowest recommended hardware is a Pentium-90 with 32 megs of RAM and 1 gigabyte hard disk. This will accomodate 40 users, so a small home network should run just fine on similar hardware.
I’d like it if someone came out with an inexpensive, mini-tower Celeron 300 with 64 megs of RAM, serial, parallel and video on the motherboard, and two (or better, three) PCI slots. Such a machine would be a perfect platform for a network appliance/turnkey system.

Added to the Geek Page: IP netmask information and HTTP error codes. If you have any other good sources of technical information you want to see preserved on the web, please email a link to me.
I’ve wanted to replace my home firewall (A Pentium 233MMX running Linux, IP Masquerade and IPCHAINS) for some time, and have been looking at alternatives. There are several alternatives:
FLOPPY-BASED FIREWALL:
Pros:
Doesn’t need high-end hardware (486, 24+ megs RAM, no hard drive is sufficient for most implementations)
RAM-based operation: if the firewall is compromised, power cycle it to go back to original config
Uses existing IPCHAINS knowledge
Uses existing hardware
Quiet, doesn’t need a power supply fan or hard drive.
Cons:
One More Computer to run…
Most require custom floppy formats to allow room for Linux 2.2 kernel
DEDICATED FIREWALL/SERVER COMPUTER:
Pros:
Have lots of hardware laying around
Uses existing IPCHAINS knowledge
Don’t need to masquerade services on firewall computer
Cons:
One more computer to run…
Several new points of failure (power supply, hard drive, etc.)
FIREWALL APPLIANCE:
Pros:
Convenient, web-based administration
Quiet
Cons:
Less flexible than traditional firewalls
No Packet filtering
No intrusion detection features
Limited logging
I’ve tested the Linksys BEFSR11 Cable/DSL router, and have two other routers on order – the SMC Barricade and Allied Telesyn AT-220E. Both the SMC and the Linksys have comparable firewall facilities, but the SMC adds a 4-port ethernet switch for $20 less than a similarly configured Linksys model (The BEFSR41) , and adds a print server. Connect your printer to your firewall and share it with Windows and UNIX hosts – pretty nice.
Many of these appliance firewalls don’t provide packet filtering, but rely on NAT and RFC1918 addressing in the protected area to provide protection to the internal hosts. Since you can’t get a route to 172.0.0.0 from the outside, you’re relatively safe. I’d like to be able to provide some filtering capability for those ports I do allow (say, only allowing certain IP addresses access to a POP server).
The Linksys router is one of the more popular routers, and it performs adequately for most home users. I’m running several services on the outside (including this web server). In order to make this server available from the outside, the router performs what is known as “Port Forwarding”. Port forwarding is a way of making specific private services on the protected network available from the outside world. For example, say you have a WWW server in your protected network that you would like to share with others. You add a port forwarding rule to the firewall forwarding port 80 (WWW) traffic to a host (your WWW server) on the protected network.
Someone on the outside wanting to see your web server would point their web browser to the “outside” public IP address, and the router would forward requests to your internal server.
The Linksys only allows 10 ports (or contiguous port ranges) to be forwarded, which is sufficient for most DSL or cable users, but a little tight for someone running a public server.
I’ve seen random lockups where the linksys doesn’t respond (and my network is isolated from the internet for 5-10 minutes at a time. I don’t know the cause of this. I’ve updated my router firmware to the latest version from Linksys’ web site, and the problem remains. Linksys has gotten some bad press regarding reliability and their ability to fix problems; some complain that their fixes introduce new problems, or don’t address issues.
The Allied Telesyn router shows a lot of promise. It appears to have more full-featured port-forwarding (allowing you to forward port X on the outside to port Y on the inside, for example, and appearing to allow more port forwarding rules than the SMC or the Linksys, which allow 10. It also features a DNS proxy, and firewall software that includes stateful packet filtering, logging to syslog or email, intrusion detection features, and packet filtering.

Systems Update
We’re mopping up after what seems like one of the rainiest winters on record! It’s been sunny for a few days straight, so my leaky office roof can finally dry out, and work can continue on my employer’s heating system.
www.kataan.org is doing nicely; it’s hosting my mail, running this web site and providing network services for my internal network. Go, Red Hat!

Dear Mr. Vernon,
We accept the fact that we had to sacrifice a whole Saturday in detention for whatever it was we did wrong. And what we did was wrong. But we think you’re crazy making us write an essay telling you who we think we are. What do you care? You see us as you want to see us. In the simplest terms, the most convenient definitions, you see us as a brain, an athelte, a basket case, a princess, and a criminal. Correct? That’s the way we saw each other at seven o’clock this morning. We were brainwashed.

.plan files
Remember .plan files? I found my old .plan:
Here it is again. Some clueless FOOL talking about the “Information Superhighway.”
They don’t know JACK about the net. It’s NOTHING like a Superhighway. That’s a BAD metaphor. Yeah, but suppose the metaphor ran in the OTHER direction. Suppose the HIGHWAYS were like the NET. All right! Severe craziness.
