I had a DD-WRT router that was dropping a lot of packets. I got a lot of errors and that caused poor playback in Netflix and especially MLB.tv. It wasn’t a bandwidth issue. My wireless network connection was just too noisy. I had to adjust my DD-WRT TX power to fix it.
I probably adjusted it the opposite way you would expect. Read more
Insurance companies are starting to offer discounts if you plug one of their devices, often called a RightTrack or SnapShot, into your car’s ODB2 port.
One of my college buddies asked me about them when his insurance company offered his family a 5% discount to plug these into their cars, and then make them eligible for up to another 25%. Those are compelling numbers. So what are the potential drawbacks?
Since my advice on selling other makes of trains was popular, I thought I would give similar advice on selling Marx trains. Marx never got the respect that its competitors got, but its trains have built up a following over the years, and in the last decade as I’ve watched prices on competing trains slide, Marx has held its value.
Don’t expect to get rich selling off your Marx trains, but if you keep your expectations realistic, you’ll find an eager buyer, or ideally, at least two interested buyers so you’ll realize a good price at auction.
I had a Java app pointing at a Forcepoint (formerly known as Websense) proxy server. The proxy server wasn’t working, and the app was giving me a 407 error.
We had Websense set to require NTLM authorization, but it turns out Java won’t do NTLM, so the Java traffic wasn’t even showing up in the monitor.
My workaround was to have users open a browser, then go to any web page immediately before opening the app. By letting the browser authenticate for it, the Java app worked thanks to Websense having the credentials cached.
If you want, you can launch the applet with a batch file that uses IEcapt to hit any web page, then starts the applet.
I lost an afternoon troubleshooting a Websense non-issue. A web site related to Salesforce wasn’t working, and any time something like that happens, Websense goes on trial. About all I can do is make sure it’s a fair trial. Such is the life of a proxy administrator. And in this case, Websense was innocent–the guilty party was a dirty, no-good domain squatter. It’s a business model. And people wouldn’t do it if it didn’t work. Here’s why domain squatting works.
The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses. I hate to be flip, but MAC address filtering doesn’t help, so why bother?
The reason is because your MAC addresses are broadcast as part of the network traffic, and it’s unencrypted. So your MAC addresses aren’t any secret at all. So it doesn’t do any good. One could argue it doesn’t do any harm. But it adds an extra step every time you put something on your wireless network. Why go to the inconvenience if you don’t gain anything from it?
I got a couple of questions about my recommended DD-WRT settings, but I’m going to start with the question about why not to hide the SSID. It actually turns out that hiding your SSID is bad for you, and makes your security worse. I’ll explain.
