- accelerometer not always responsive
- spelling correction very good
- why is search in Calendar app worse than searching entire iPod for calendar items?
- conflicts with calendar events when coming from offline to online not handled well, i.e. events are deleted (need to get more details on circumstances)

More observations about iPod Touch

2011-07-10 - Spark in the Summer: Tim Wu on The Master Switch
- Podcast
- Tim Wu, who coined "net-neutrality" and author of The Master Switch suggests that we are entering a stage of consolidation and monopolization in the internet arena since historically after 15-20 years of a new technology, one corporation comes to dominate
- Google has more potential power to censor than the government
- For many people, Facebook has more personal information about them than the government
- net-neutrality or principles like it are a ways to prevent a single corporation from staying in power simply by shutting out others

Evaluating Mobile OSes
My Windows Mobile 6 phone continues to perform erratically (rebooting itself now and then) although the battery life is now reasonable due to battery replacement. So still wanting to replace it and then give my iPod Touch to my wife. The article Mobile OS Showdown: Android, BlackBerry, iOS, and Windows Phone 7 provides several slants for comparing features of the mobile OSes. Some criteria and considerations that sets the mobile OSes apart:
Some thoughts:
- Two-way sync with multiple Exchange-protocol (e.g. Google) calendars
- Customization, e.g. different virtual keyboard or home screen
- What security granularity and warnings when installing new app?
- SSL connection when connecting to retrieve email, calendar?
- Voice control of device and extent
- Turn-by-turn navigation
- Important: Does default browser support Flash? HTML 5?
- How are email attachments handled? Can choose application to open them?
- Open file system structure
- What formats can default media player handle?
- VoIP calling
- Multi-tasking for third-party apps?
- OS-specific features: WP7 Live Tiles and Android's Notification pane
Some thoughts:
- Apps - is developing a WP7 app that integrates well with the OS so different compared to the other OSes that developers will avoid offering a WP7-version of their app?
- Office suite - how good is Android's native Google Docs app? How well does it work offline?
- iOS seems to marry data and application together, that is, data resides in one application and to access it, you have to use that application. Another way of looking at it: You can't choose which application to open a piece of data. Generally this is not a problem which seems to be iOS's design philosophy

Informal and incomplete web browser comparison
Evaluations in progress:
| Pros | Cons | |
|---|---|---|
| Internet Explorer (ver 8.0.7600 ...) | Flash media doesn't appear to crash browser |
|
| Mozilla Firefox (ver 3.6.6) |
| Flash media can slow down or crash browser |
| Mozilla Firefox (ver 4 ...) | N/A | N/A |
| Opera (ver 11.01) |
| Some web sites don't render well and functionality is hurt on others (e.g. Google Docs spreadsheets) |
| Chrome (ver ) | N/A | N/A |
| Internet Explorer (ver 9.0.8112 ...) | Didn't bother using further | Sometimes difficult (or impossible?) to restore last browsing session, that is, the open tabs and their loaded locations, after shutting down browser. This is a show-stopper. |
PowerShell and other essential Windows software for the geek
All are free or non-expiring trial versions:
- PowerShell - after using Linux terminal windows extensively (and even Putty for that matter), cmd.exe just won't do. PowerShell is a good Windows alternative, rather than Cygwin and the like. However, response is somewhat slow for typical commands you would type in a Command Prompt window.
- VirtualBox - compared to Virtual PC and using a Linux guest OS: better performance (seems to respond faster), mouse pointer integration (mouse pointer can move to and from host OS seamlessly), able to install Ubuntu (with Virtual PC, because of strange display issues, could not install Ubuntu or Fedora but OpenSUSE works)
- WinMerge - text file comparison tool. Also can find differences between directories
- Notepad++ - developer-level text editor
- PrimoPDF - print driver that enables creation of PDF files (rather than printing to hardcopy)
- Firefox Add-ons:
- Delicious Bookmarks
- Selenium IDE
- Firebug
- Some more Windows geek tools under my Delicious bookmarks
- More (short write-up to come):
- FileZilla
- Putty
- FreeMind
- Git
- UMLet

Viewing DOCX files
Accurate rendering from best to worst:
- MS Word (obviously)
- MS Word Viewer (of small sample of .docx files I've tried, they look as rendered in Word itself)
- Google Docs
- Open Office (possible problems include bullet numbering incorrect, side bar layout messed up); don't trust the rendering as what you see can be misleading

Streaming to PS3
We purchased a PS3 more than a year ago. Still don't know why--I think we thought if we had company over, they could play games on it. But in 2010, we didn't have time for much "company" :-| So to turn a bad purchase into a better one, I lent it to my sister who made use of it. Recently, got it back and trying to see how to play media saved on desktop computer onto the HDTV which has no network connection: The key is a PS3 connected to our wireless network and a DLNA compliant Media Server.
At first tried Windows Media Player but problems getting option of "Turn on media streaming ... " on one computer running Windows 7 Ultimate. Only get "Turn on media streaming with HomeGroup ... ". This is what I want:
So rather than jumping through WMP hoops, tried using PS3 Media Server. Very easy to install and set-up, but some gotchas:
So far, the results seem to indicate that "Data rate/Total bitrate" is a large factor in whether stuttering of the video/audio occurs.
To eliminate stuttering, with a better network connection where no ethernet ports are available, I'm considering powerline networking (this is just one product in this category); not sure whether I'm willing to spring for that yet.

So rather than jumping through WMP hoops, tried using PS3 Media Server. Very easy to install and set-up, but some gotchas:
- PS3 divides media into Photo, Music, Video, etc. so if you're looking for a video file while you're in the Photo branch, don't expect to find any!
- By default, PS3 Media Server shares all drives. For security reasons, you probably want to limit this to specific folders
- PS3 seems to have a limit to the depth to which it can browse folders. So if you have shared a really deep tree on your media server, PS3 may not be able to navigate to the media you want.
| Frame width | Frame height | Frame rate (fps) | Data rate/Total bitrate (kbps) | Stuttering? |
|---|---|---|---|---|
| 560 | 416 | 25 | 1444/1828 | Yes |
| 608 | 336 | 23 | 1012/1140 | No |
| 640 | 272 | 23 | 1188/1380 | No |
| 640 | 352 | 25 | 1117/1245 | No |
| 640 | 480 | 29 | 896/1024 | Rarely |
| 720 | 416 | 29 | 1061/1445 | No |
| 1280 | 528 | 23 | 1728/1997 | Yes |
| 1280 | 544 | 23 | 2274/2717 | Yes |
