Thoughts and Ramblings

General things I find of interest.

New Semester

Well, the semester is now into its third week and things are going alright. I just had my first week of teaching lab, and things pretty much went as expected. The problem is that the students are expected to do some assembly within lab, but non of them have seen x86 assembly in class yet. Essentially, I had the fun of teaching them the basics of assembly just so they could do the lab.


Site Block in Search

Lately, since I have been investigating the idea of getting a new cell phone, I have started many searches on the topic. My parents just bought a Katana from Sanyo, and so I have been searching for information on their behalf as well. When I do certain searches in google, such as katana ringtone bitpim, I get a whole host of crap results from blogspot.com. So my solution: Whenever I do a search, I simply blog results from blogspot. So the above search becomes katana ringtone bitpim -site:blogspot.com and surprise surprise, I get relevant results!


Will Not Fix it

I had an interesting exchange with the CIS people here at TAMU concerning their VPN. A bit of background:

  • A&M uses Cisco’s VPN client (and there concentrator too IIRC).
  • There are two modes for the VPN. The normal mode which forwards all traffic through the VPN and the “split-tunnel” mode which only forwards TAMU destined traffic through the VPN
  • Upon connecting to the VPN, the client changes your DNS server settings to those specified by the server (in both modes)

I tend to use the split-tunnel mode more often than not because I only care to get through the firewall. Now here enters the situation. Slowly, when I was off campus, I noticed that I could not reach certain websites while using VPN. They were perfectly reachable when not using VPN though. So, I tracked down the problem and reported it:


Searching for Digital

My parents got a new HDTV. Good ol’ Walmart had their 6am sale on black friday, so we all piled in the truck early in the morning to pick up a good deal. Got it home and started to test it out. It seemed to work just fine.

We started testing out the HD part of the TV. Problem, my parents don’t live too near a big city, so all the stations are distant. As a result, picking up the digital channels can be painful. To make matters worse, when one does a rescan on the TV, it forgets all the previous digital channels it found. Here enters the method by which digital channels work. The digital channel for channel 5, for instance, is not on channel 5. It is somewhere else. My dad discovered that if one manually enters in the location for a digital channel, the TV can figure it out and pick it up. So, does one can play the guessing game to find them? Not quite. Government regulation to the rescue. The FCC has a database of all the stations and their licenses. So, simply look up the station by its call sign, location, and/or channel, and it list the info about them. Click on the engineering data, and there is the list of all their broadcast rights, including the channel where their digital transmission is hidden. So, simply tune it in, pray that the set can receive the weak signal, and then add it to the list. Ought to keep my parents busy for the next few weeks, assuming they aren’t still picking up signals from a few states away.


Bad Drainage

On Tuesday, I was sitting in my apartment, and I could hear the distinct sound of cars driving through water on the road. It was not supposed to rain so I looked outside and couldn’t see any water. I then went out to the parking lot, and I could see water flowing by very quickly about 3 inches deep. It was also very murky. The next day, I concluded that a water main broke somewhere nearby and that the water flowed down the street. In a great feat of design, the drainage seems to divert about 70% of the water flowing down the street into the parking lot to my apartment complex. Oh well, glad I didn’t have anywhere to go.
