There's new feature comes with Gmail, filters for new mails.

   

We could custmize our own rules with it for various automatic operations such as attaching tags, forwarding, delete, archive.

   

I mainly use tags for nearly all filters and use archive for some subscribed mails which comes lots of each day and no need to pay special attention.

As default, new created filters won't be applyed to existed mails. there's an option for applying filter on the old mails which matchs the filter during the creating process.

Father moe, I got a tip after several tries.

If you want a rule search logic as "A or B", you can input "A || B" as the rule text. Any way else, I tried "A B", "A or B", they don't works.

In this way you could merge multi filters which have different rule search but same rule actions into one filters, just like this one merged.

   

I bought a PCMCIA card reader for reading SD memory cards within my thinkpad.

After a try, I found MCR-5A will take cpu to 100% load when writing or reading for the SD card within it. 

Made a search on Internet, there's simular problem from others . Also refered to the spec on website of Buffalo . MCR-5A and MCR-16A are both don't support the sd card greater than 1GB and both are 16 bits card.

I use 2GB sd card and am not happy with 100 cpu load, seems have to try others. 

I bought a 2 GB SD memery card(kingmax 150x) for pda, I also use this new sd card on my *ist DS camera as backup.

But there's a problem that the DS can't save the pictures with the new card even there's still free space available.

I found useful link on Pentax website, the firmware version 1.01 only support max 1GB sd card, when you use a sd card greater than 1GB, the exceed space won't available.

Solution

Thew new version of firmwares are available, can work out with this.

• v1.02
• v2.00
• v2.01(current version)

I'll make a upgrade for my *ist DS.

Reference

Unicode file always set the first byte as certain content to indicate the file format. We could use edit tools like UltraEdit open the file in Hex mode to see the byte.

Byte order mark	Description
EF BB BF	UTF-8
FF FE	UTF-16, little endian
FE FF	UTF-16, big endian
FF FE 00 00	UTF-32, little endian
00 00 FE FF	UTF-32, big-endian

Note: Microsoft uses UTF-16, little endian byte order.

When I use WM 2003, the sync feature via USB was all right(cant by BT), but for current WM 5.0 OS, continue to failed for sync via USB.

I found a link below, it really helpful.

I remove my BT device in my Device Management. and then update drivers by Internet. the new drivers come and with a new applet in control panel.

follows the article, all problems settle down, get successfully on sync via bluetooth.

When you run a .exe file to install Pocket PC application from desktop PC, the .cab files will be extract into following folder in the descktop PC.
