DMC-TZ3 Zoom

So I got the Panasonic DMC-TZ3 for my birthday, which was July 10th!

It does take decent pictures, but they do seem a little feathery when you zoom in. My old Canon S200 seemed to take sharper pics, but this difference isn’t noticeable unless you zoom in. Here’s two sample pics of a sunrise up at the lake.

The camera does have an incredible zoom, 10x, for its size. The first pic is of the sunrise without zooming, the second is a full zoom:

I got the camera on NewEgg.com for less than $300, and a 4GB SDHC card for $38, it also came with a free 1GB card, but I felt that it would be too small for extended trips.

Nokia N73!

I ordered the phone from Buy.com. They had it for $339 and a coupon for $15 off any purchase over $200. Subtotal after the coupon was $320, but as they have a warehouse in Massachusetts there is 5% sales taxes on that, which add $16 to the total. But, that’s still cheaper that most of the used models on Ebay.

I went for the free shipping is estimated at 7 to 9 days, but if I’m lucky they’ll ship from the local warehouse and it won’t take too long.

This is good news:

The phone can be mounted as a USB drive so I had no trouble transferring photos to my Linux running computer and had no need of any special software. Nevertheless, I’ll be installing the Nokia PC Suite at work to get our Outlook calendar syncing.

Which means I’ll hold off on ordering a Bluetooth dongle from Newegg, and see if a cable is included with the Phone. Buy.com doesn’t say what’s in the box, but the same phone from Nokia’s US site shows it ships with a cable, but for $100 more.

I’ll need a memory card to hold pics and save on data charges from sending pics via T-Mobile’s network. But, I’ll wait until I get the phone before I order anything else related to the phone, except for either screen protector or a case to protect it.

Hmmm, phone lust

Got that new mobile phone lust. Some friends at home (Mick McG, and Murph) had Nokia n73 phones. They seemed OK, when I played with them. But, looking at the specs, feature list, and the pretty decent photographs it takes has given me that new phone lust:

Nokia N73 Review

All this thing is missing is Wifi support for Web surfing off the phone company’s network. The iPhone looks really cool too, actually cooler, except here in the US you need to sign up with ATT, whom used to be ATT Wireless.

I had an ATT Wireless phone for 2 weeks when I got my first mobile phone here in the US, a Siemen S45 I think. But the quality of the service wasn’t that good, ATT was in the middle of changing their network from CDMA or TDMA to GSM. I had 28 days to return the phone and cancel the service, so I brought the phone back and signed up with T-mobile who allowed internation text messaging and at the time ATT didn’t. For the next SIX months I got bills from ATT claiming I still had service and had to pay. Every time I phoned their Customer Service, whom were always really, really nice, it took 30 to 45 minutes on hold to get to a human. This is why:

ATT System Upgrade goes haywire

Eventually, ATT Wireless got bought by Cingular, whom got bought by ATT. ATT & ATT Wireless were 2 seperate companies, so ATT renamed Cingular ATT Wireless.

Back to the iPhone, neat piece of technology, but I cannot imagine that Cingular were able to digest ATT properly and get their systems meshed and working properly and I doubt if the new ATT Wireless is much better. I’d wait a few years before using ATT Wireless.

Now if I could get an unlocked iPhone and use it with T-Mobile I’d be tempted, but I think to get full use of the iPhone’s phone feature it would need to be an Apple approved company. Articles I’ve read about the iPhone in Europe claim that European phone companies are or were balking at it because the iPhone requires Apple servers or technology embedded in the phone company’s network or systems for it the work as advertised which means it’s breaks the standard for GSM phone.

And, how do you keep the iPhone from getting all scratched to shit like my first iPod? My first iPod was a 3G 20GB, I had it for a week and kept it in the Apple supplied carrying case, and it got all scratched to fecking shite.

Jetspeed Login Portlet & WebSphere 6.1

How to get the Jetspeed Login Portlet to work with IBM’s WebSphere 6.1. The default Jetspeed login Portlet doesn’t with WAS, it does work with Tomat, there is an alternative Login Portlet that can be used that will work with WAS. Follow the steps below to disable the LoginPortlet and enable the PortalLoginPortlet.

1. WAS version

First make sure you’ve running at least WAS 6.1.3 or higher.

2. PortalFilter & web.xml

Edit the web.xml file that’s in the Portal’s WAR file and uncomment the PortalFilter:

  <filter>
    <filter-name>PortalFilter</filter-name>
    <filter-class>org.apache.jetspeed.login.filter.PortalFilter</filter-class>
  </filter>

  <filter-mapping>
    <filter-name>PortalFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

3. LoginPortlet & PortalLoginPortlet

Replace the LoginPortlet in your default-page.psml with the PortalLoginPortlet:

<fragment id="dp-12" type="portlet" name="j2-admin::LoginPortlet">
      <property layout="TwoColumns" name="row" value="1" />
      <property layout="TwoColumns" name="column" value="1" />
</fragment>
 <fragment id="dp-12" type="portlet" name="j2-admin::PortalLoginPortlet">
      <property layout="TwoColumns" name="row" value="1" />
      <property layout="TwoColumns" name="column" value="1" />
</fragment>

You may need to change theĀ  “fragment id” also.
4.Edit jetspeed-portlet.xml

Add this to your j2-admin’s WEB-INF/jetspeed-portlet.xml, immediately below the first portlet entry:

<portlet>
        <portlet-name>PortalLoginPortlet</portlet-name>
        <js:security-constraint-ref>public-view</js:security-constraint-ref>       
        <dc:title>Portal Login Portlet</dc:title>
        <dc:creator>J2 Team</dc:creator>
</portlet>

5. Custom PSML?

If your using Maven 2 to build a custom Portal, override the the default page by putting the modified copy of your page in

portal/src/webapp/WEB-INF/pages

Firefox 2 & Tabs!

Yup, Firefox 2’s tabs annoy me a bit, if you’ve too many open you can’t see them all. Here’s how you go back to the old Firefox 1.x behaviour:

I met Aza, who wrote the above article, at the Ajaxian Conference here in Boston late last year. Nice lad, very smart, interesting ideas, and their product Enso Launcher is a interesting concept. His presentation at the Ajaxian conference really highlighted how you can use the keyboard, via Enso, to do just about everything on the desktop in an easy human thinkable way. It’s too bad they don’t have a version of Linux, I think the type of users who use Linux could really avail and use and promote it.

Camera!

Finally made a decison and settled on the Panasonic DMC-TZ3 and ordered it from NewEgg.com. Went with the Silver Model as it is $30 cheaper than the Black Model. Other cameras I’d consider were the Canon G7 and the Ricoh R6. The Canon beside various auto-modes also allows almost complete manual control, but is almost $200 more. The Ricoh R6 is comparable to the Panasonic, but is only available from one vendor in North America (it’s widely available in Europe & Japan), and is about $70 more than the Panasonic.

A review of the Panasonic DMC-TZ3:

And a comparison with the Canon G7 that I had also considered: http://forums.dpreview.com/forums/readflat.asp?forum=1033&thread=22633538

The Canon G7 is $500 vs ~$300 for the TZ3. Looks like the Panasonic takes comparable pictures, whereas the Canon allows one to use more, much more manual settings, looks really cool, is a bit bigger …

Xorg stopped working …

Updated my Debian system last night and this moring Xorg wouldn’t work. In /var/log/Xorg.0.log at the end of the file is this:

(II) LoadModule: “nvidia”
(WW) Warning, couldn’t open module nvidia

Fatal server error:

Looks like /usr/lib/xorg/modules/drivers/nvidia_drv.so is missing.

Found the fix here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=420177

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428580

To create the .so file do the following (as root or using sudo):

cd /usr/lib/xorg/modules/drivers

gcc -shared -o nvidia_drv.so nvidia_drv.o

Cameras!

Time for new camera. My Canon s200 takes great pictures, but I think it’s starting to show its age. I finally settled on a Panasonic TZ1, for it’s 10x zoom, and because Newegg had it for $189 with a 1GB SD-card.

Panasonic TZ1 Reviews:
http://www.imaging-resource.com/PRODS/TZ1/TZ1A.HTM
http://www.dcresource.com/reviews/panasonic/dmc_tz1-review/index.shtml
http://www.dpreview.com/reviews/panasonictz1/

By the time I was ready to order they had sold out of it at that price, and due to other issues with the camera I don’t think it’s worth over $200. I’d decided on the TZ1 mainly because of it’s 10X zoom, Image Stabilisation, and low price at Newegg. In low light the TZ1 seems to produce poorer pictures (than the Canon’s listed below) and it only has a LCD screen and no viewfinder. So, as a sub-$200 compact-camera it would be a great deal, but for over $200 I think there are better cameras to consider with more MP’s (Mega-Pixels) and better ability in low-light.

I’ve been looking at the following 3 Canon cameras.

First up the Canon A710:

http://www.dcresource.com/reviews/canon/powershot_a710-review/
http://www.dpreview.com/reviews/canona710is/

Most of the reviews give it a thumbs up, and comparable quality pics to the more expensive Canon G7 (see below). But, I don’t like the fact it uses AA batteries, which means having to buy rechargeable batteries & charger and hauling those around. I prefer having a camera that comes with a rechargeable battery and charger, which usually ends up as a less bulky solution. It’s 10 Megapixels, and has a 6x Optical zoom.

Price is about $250.

Next the Canon S3:

http://www.dpreview.com/reviews/canons3is/
http://www.steves-digicams.com/2006_reviews/s3is.html
It’s a 6 Megapixels whereas the A710 and G7 are 10 Megapixels. It takes great pics, and has a 12X optical zoom! But, it takes AA batteries and is bigger than the other 2 Canons.

Price about $300.

Canon G7:

http://www.steves-digicams.com/2006_reviews/g7.html

Great, great camera, also looks great in a sorta of retro-way. It’s more compact than the other 2 Canons. But, it’s about $450 and has many complaints from users of previous Canon G Camera users for being crippled compared to previous G models.

Here are the 3 Canon cameras listed feature wise side-by-side.

I just discovered the Panasonic DMC-LZ7K, 7.1 MP, 6x optical Zoom:

Less than $200 at newegg, with a 1GB SD card. But, it takes AA batteries …
