Grading papers

March 16th, 2008

Well, I’ve been grading papers for the past 2 days. This is assignment 2, an essay, whose grading is very subjective. In this case, it means that I’m not failing half of the class like last time. I give a lot of credit out. It takes a particularly poor paper to do badly.

Also, the subjectivity of the grading for this assignment gives me a lot of leeway. I’m not constricted to a specific grading rubric. I can be a nice grader.

I don’t like failing students.

Internet is down…

March 13th, 2008

The internet at my apartment is down, and has been for over a day now. I’m connected through my phone, so it’s not a deathly situation, but it really sucks.

When IRC gets old…

March 12th, 2008

Some days, there’s just nothing to do. IRC has gotten old. The web has gotten old. Listening to audiobooks has gotten old. Listening to classical music is getting old. Programming has gotten old. Grading assignments has gotten old.

What is there left to do?

TV is old too.

How to use your SCH-i760 as a modem with Mac OS X

March 10th, 2008

It is possible to use a Samsung SCI-i760 as a modem with Mac OSX. Verizon Wireless will be no help here, but hopefully I can. After literally months of hunting around, I have figured out how to do it. Here’s how:

You will need three files for this. They are Verizon Wireless’s VZAccess program, BTModem.exe, which creates a dial-up networking bluetooth interface, and VerizonWirelessModem, a modem script. I am not certain that VZAccess is required, but I had it installed when I managed to get this to work, so I’m going to recommend that you install it as well.

First, install BTModem.exe on your phone. Copy it over any way you can, such as with a memory card or using the Obex FTP application on the phone. Run it. It will create a bluetooth serial port to which your computer will connect and use as a modem.

Next, install VZAccess. The steps for this are pretty obvious.

Finally, you need to install the modem script. Unzip it and copy it to “/Library/Modem Scripts”.

Then, you need to set up the serial port. I assume that you have already paired your phone with your computer.

Go to the System Preferences and choose the Bluetooth pane. Select your phone, then click on the gear icon. Select “Edit Serial Ports…”. There should be one listed already, named with the bluetooth name of your phone followed by “-i730ModemS-1″. If there is not, click on the plus icon, and it will be added.

Select the serial port, and set the Protocol to RS-232. Set the Service to “i730 Modem Serial Port”. Check both “Require pairing for security” and “Show in network preferences”. Here is what mine looks like:

BTSerial.tiff

Next, back in the System Preferences, choose the Network pane. Select the “-i730-Modem-S-1″ interface, and name it something like “VZW”. Click Create.

NInterfaceAdd.tiff

Now to edit the modem settings. Use “#777″ as the telephone number. Account Name is “(yourphonenumber)@vzw3g.com”. For me, this was “5402728159@vzw3g.com”. The password is “vzw”.NIntefaceConf.tiff

Next, click on Advanced. Set Vendor to “Other”. Once you have done this, set “Modem” to “Verizon Wireless”. Click OK.NModemConf.tiff

Now, disconnect your phone from the net if it is connected. Your modem is now set up.NInterfaceDoneConf.tiff

Disconnect any other active network interfaces, such as an Airport. If your computer is already connected to the net, it doesn’t seem to work. Click “Connect” to try it out. :)NInterfaceConnected.tiff

A side note: I have discovered an intermittent problem that undoes some of this connection stuff. Occasionally, for no apparent reason, my mac forgets that the serial port, “i760 Modem Serial Port”, exists. When this happens, go to the “Edit Serial Ports” dialog from the Bluetooth preferences, and click the “+” button below the list of serial ports. It should show up immediately. If you have already set up the VZW network interface, you don’t need to do that again after re-adding the serial port.

Side note 2: Sometimes, for example when you get a phone call while connected, OS X seems to hang on the disconnect step. It will say it is disconnecting, but never finish, and not let you reconnect either. Internally, this is the PPP daemon getting hung on a suddenly gone serial port. The solution to this is similar to the note above: If it hangs on disconnect, go to the bluetooth preferences for the device, click “Edit Serial Ports…”, and then remove the serial port. Click apply. Suddenly the stalled disconnect will finish. You can then re-add the serial port and connect again.

Sophie’s World

March 5th, 2008

I bought Sophie’s World on audiobook from iTunes yesterday. I’ve been listening to it practically non-stop. I love this book.

I guess I’m a bit of a philosophy nut. I tried to get Lauren to read it, but she said it was boring, and stopped. Oh well.

Ultra-fast chemistry lab

March 3rd, 2008

I got through my chemistry lab today nicely quickly. My partner and I used batch processing and parallelization to do the trick. I measured with the spectrophotometer and cleaned test tubes while he mixed solutions. We got it done in about an hour, way before everyone else. It was pretty awesome.
