Fiona Apple saga shows Sony’s core dilemma | The Register
Some stories are painful to read. This is one of them, but probably not for the reasons you think.
Beware Windows 2003 Service Pack 1
by danlor on Apr.02, 2005, under Technology, Work
While it has been tested for eighteen months, it still is not ready for prime time. After installing it on a clean 2003 server at work, the server was nolonger bootable. Uninstallation failed as well. The machine locks up during boot, right after the splash screen shows.
So… You have been warned.
Lots of good stuff
by danlor on Mar.30, 2005, under Technology
I’ve been in withdrawl for quite a few months now since the divorce. You might wonder what from. My Tivo of course. I went back and forth a few times on buying a new one, but finally decided to go the home brew route this time. After lots of thought and debate, I decided to give the snapstream beyond tv stuff a try. It started out bad. The machine I wanted to use had a graphics card that was too old (no directx 9), and the software simply would not allow me to use it. I could record, but not view. I then went ahead and built a machine from scrap that met the software’s needs. It took about two days of work, but I got everything working pretty good. I had to dig on the internet for drivers and stuff, and the IR blaster codes took me almost a week to get right.
Now that everything is up and running, I’m pretty happy. The interface is clean enough to use, and the features are similar to a real tivo. There are some notable missing goodies like tuner state persistance while going to the main menu. If you pause a show, go to the menu to schedule a recording for a show you just saw a comercial for… then you not only lose your place in your show, but the stupid tuner will retune your channel to what ever you were looking at in the guide.
On the plus side, there are some wonderful additions like webstreaming and copying your shows to your laptop for viewing on the road. You can also burn the video files right to a dvd.
I would not recommend this product for the casual computer user.
Upgrades Complete

Jenn and Joe are now upgraded to the same rev as me for their blogs. Yea.
In other news… Ripcord is knawing on my leg again. I think it may be time to start working on the suite once more.
Redmond Rides Again

In typical “helpful” MS fashion, they have helped the world by taking down the site of one of the best ani spyware vendors. Since the link is gone to the download, you can get it from here:
Giant Antispyware
Cisco VOIP Mitigation
by danlor on Dec.14, 2004, under Technology
I’ve been working with HP trying to figure out what we can do here about these phones. It is not a simple problem. Most hardware can deal with multi-link loopback conditions using technology like spanning tree, but how the hell do you handle a loopback on the same link? It is technically impossible to do unless you actually go ahead and create a cable with shorted out pins, or litterally looped the wires back into the connector. It is not condition you would normally ever see by accident.
So far I have had limited success. Spanning tree has been usefull in limiting how many loopbacks I get on the switch. It will shut down all loopbacked ports except one. The second step was to turn on flood control (throttling). This keeps the ports from shutting down the entire switch with broadcast storms.
The final solution is to get HP to patch the switch to sense this insane condition and shut down the port. I have no idea when I will get that.
Absence of the best boss ever
by danlor on Dec.10, 2004, under Technology
I’m moving into a scary time now. My boss is on medical leave for a month while I’m alone maintaining our network. We have two positions open… Anyone want a job?
It will suck being with out her for so long. I have to say that she is easily the best boss I can ever hope to have.
If you answered yes, then I am living your wish. I don’t know how long it can last, but I’m enjoying it while I can. Here’s to hoping she makes a speedy recovery!
Hell has frozen over
by danlor on Dec.09, 2004, under Technology
Last thursday, I had another Dell machine hard crash the disk drive. I’m not really sure why so many Dell machines crash this way. Anyways, I was not sure at the time that the problem was the disk drive. I could not boot windows, and I could not reinstall windows without disk errors. I have had similar problems on hp machines that were caused by wrong ram modules being installed.
So, after testing a few things out, and getting a disk failure message in the diag util, I called Dell up to ask advice. The tech was convinced it was a drive failure, and he convinced me too after about 15 minutes of corrolating symptoms. He went ahead and sent me a drive.
If I had known it was a drive failure, I would never have called them. I have been through too many refurb disks with these guys to screw around with that. I always put brand new disk drives in machines. It’s cheaper in the long run.
You can imagine my shock when I opened the Dell repair box to see a shiny new shrink wrapped sealed drive inside. I could not believe it. They sent me a new drive. I had already built the machine with a drive of the same model, so I did not use it, but put it on the shelf for next time.
May be these guys are finally waking up. Melissa was able to get a new TFT panel out of them last week without even a fight. I sure hope they are coming out of thier funk.
Another Amazing Week in Technology
by danlor on Dec.07, 2004, under Technology, Work
So. Where to start.
Just to show that I am an equal opportunity bitcher, I had an hp d530 ultra slim blow a motherboard last week. hp was nice enough to send me a used motherboard to replace it. Unfortuantely, they did not make sure it was usable before shipping it. The video connector was mostly broken off the board. They did not argue and sent me working used board. At least it works now. TAKE NOTES DELL!!!! [sigh]
Ok, so… the fun of my day today. Everyone is really keen on all these lovely cisco IP phone we have now. I have to say the whole thing has been quite mixed from my point of view. On a scale of 1 to 10, our success runs in the 3-4 range.
And now that I have discovered the most wonderful “feature” ever, I can tell everyone I know to run away from these pieces of shit screaming. As fast as you can. Are you ready? You sure?
Every cisco IP phone ever made is a network time bomb. Every fucking one. Want proof? Read this:
If the phone is not powered by an AC power adapter and the phone is connected to an Ethernet switch that does not provide POE support, the circuit inside the phone’s uplink port remains closed. In this state, any traffic sent by the switch to the phone may loop back to the switch and create a loop back storm that disables the entire VLAN.
This may mean nothing to most of you non network admins, but all you real admins right now are shuddering. Read that again to just make sure you fully understand the situation.
It took out one of my branches last night. A cleaning lady knocked a powersupply loose. Took everything out: Security, atm, teller machines, phones, everything. And it can happen to anyone. Any company that has IP phones, and a mix of POE and non POE ports on thier system (everyone), are in danger. Just imagine little Suzie moving some stuff around in her cube, and accidentally plugging her computer and phone into the opposite ports. POOF the main vlan for the comapny is now DEAD! By design no less. Here is another quote for you:
Devices that are capable of receiving POE, such as Cisco IP Phones, close the loop back circuit on their uplink Ethernet port when they are powered down to enable the POE discovery pulse message to be looped back to the switch.
Again, you might want to read that twice. Cisco ip phones use the biggest mistake in networking to power themselves up. It is completely unnessesary as well. 802.3af uses resistance and capacitance on the line to determine the same thing. And it is backward compatible to NOT take your network down. how quaint.
Cisco is quick to trumpet the fact that cisco hard ware is “immune” to this problem. They claim that their hardware has loopback recovery features to prevent the vlan from crashing down. Just one problem. It shuts down real live working servers. cisco has shut down their own fucking Call Manager software (phone switch) on our network three times due to “errors”. The problem has been remedied by moving the server to an HP switch that does not suck.

High speed CHEAP photography

Another site I forgot about until Alex brought up the subject of high speed cameras. These guys took cheap disposable cameras and rigged together optical triggers to get some pretty amazing photos. Here is an example of one:

Pretty crazy considering this picture was taken by a bolt knocking a piece of cardboard free.
