newsletter

my blog now has an atom feed so you can subscribe to automatically receive new blog postings.

to subscribe to blog feeds, you need a reader such as google reader. the point of a reader is that it allows you to read multiple blogs all in a single location. the main advantage is that it saves you the time and effort of having to visit each blog one at a time just to see whether they've been updated since you last visited.

another advantage is that--since it's so much faster and easier to check them all at once--it's feasible to check them all more frequently, thus allowing you to find new posts much sooner after they are posted.

and yet another advantage is that (once you've subscribed to the feeds) you don't have to remember any links, e.g. "blog.t-rev.net". with an online reader such as google's, i can sit down at any computer connected to the internet, log in, and check all the blogs to which i'm subscribed. otherwise i would need bookmarks or favorites to remember the locations of them all for me.

update 2008-08-14: the address of my blog's feed is changing. you can subscibe to the new feed now at http://blog.t-rev.net/atom.php or http://blog.t-rev.net/xml-rss2.php

tips

Laura's phone lets you use MP3s as ring tones, but it only accepts .mmf or .amr files (at least, it doesn't take .mp3 or .wav) for other sounds, such as reminder alarms and voice mail alert tones.

after trying some other methods that didn't work, here's how to make make .mmf (SMAF) ringtones that will actually work on the samsung sync (A707) phone:

  0. download Yamaha's free WSD "Wave Sound Decorator" (for Windows) and install it.

  1. create your desired ring tone as a .wav file.

Note: it's best to make it monaural. also apply "compression" if you can. i use audacity for audio recording and editting.

  2. run WSD and drag your .wav file onto it.

  3. select "MA-5" in the drop-down box on the toolbar (upper left).

  4. if the sample rate in the status bar (bottom right) is above 24000 Hz, click "Edit" and "Sample Type" then resample to 24000. (in the process, check "convert to mono" if it's not grayed out.)

Note: WSD can also normalize, trim, and fade in/out if you didn't do all that in step 1.

   5. save it, (it saves only as .mmf format.) put it on the phone and use it.

ringtones on the Samsung A707 are limited to a file size of 300kB, which for a 19.4 second (that's how long her phone rings before voicemail picks up) mono MP3 requires you to use 112kbps (or less, or VBR).

alarm tones aren't subject to the 300kB limit. reminder alarms sound for 60 seconds or until acknowledged, and the phone allows you to use 60s of 16bit mono .mmf audio at the highest allowed sample rate, 24000Hz.
