Flickr Camera Page

Flickr has a very cool Camera Finder page. You can use this to see what the most popular cameras that Flickr users are using.

It would be really cool if there was a similar page on YouTube. It would be cool to see what the most popular video camera is being used.

CD and DVD Archiving

?? ?If you do any type of computer data backup to CDs or DVDs, you should read the NIST Digital Media Group: docs/disccare. They have some great advice on how to make sure your CDs last a long time. For example, did you know that you should be using an adhesive label on your disk. (Not sure what Avery or Meritline would have to say about that.)

?? ? If anyone knows about maintaining technology for the long run, it's the National Institute of Standards and Technology. The NIST is an agency of the U.S. Department of Commerce.

Dell Card Blank

On my work laptop computer there's a built in SD card slot. Dell provides a card blank to protect anything from going into the card slot. The card blank device also blends in very nicely. Should you loose the card blank, you can get a replacement for the K2D98 part:

Yes, for only $16.16 you can get your computer safe again! No more sleepless nights thinking about how unprotected your laptop is. Personally I think it's a waist of money. You can get a 4GB SD card for about $5. What's more, the SD card is so common now a days, you might have some from an old camera that you don't need any more.

Don't pay the extra price to protect the SD slot, put in a SD card and you'll be just as safe.

Crucial 8GB Memory

This past weekend I installed 8GB of memory in my Late-2011 iMac. Before I started, I printed up the directions on how to install the memory so that I had clear step by step directions.

I purchased my memory from Amazon Prime, they had the cheapest price ($79.95) and fastest delivery. I did learn that the iMac Late-2011 only accepts 2Gb and 4GB memory and the max memory that I can install is 16GB.

The only change I would make in the directions would that Apple suggest using any Philips screwdriver. You are best to use a Mini Precision Screwdriver set, as a regular Philip is too big for the screws.

Having more memory in the computer allows me to open up more programs at the same time, I was having slowness issues opening up iPhoto and Firefox with 2GB of memeory. More memory is essential for Parallels Desktop 9 for Mac. I should have upgraded a lot time ago.

Developers sayings

Found on several sites, here is the list of things that Programers say when QA finds a bug:

  1. That's weird....
  2. It's never done that before.
  3. It worked yesterday.
  4. How is that possible?
  5. It must be a hardware problem.
  6. What did you type in wrong to get it to crash?
  7. There is something funky in your data. OR It's a data problem, not a program problem.
  8. I haven't touched that module in weeks!
  9. You must have the wrong version.
  10. It's just some unlucky coincidence.
  11. I can't test everything!
  12. THIS can't be the source of THAT.
  13. It works, but it hasn't been tested.
  14. Somebody must have changed my code.
  15. Did you check for a virus on your system?
  16. Even though it doesn't work, how does it feel?
  17. You can't use that version on your system.
  18. Why do you want to do it that way?
  19. Where were you when the program blew up?

And the Number One Thing Programmers Say When Their Programs Don't Work:

  1. "It works on my machine..".

Flip Mino HD problem

If you having a problem with turning on a Flip MinoHD you should first plug it in for a while. For example if it doesn't turn on or it turns on and then immediately turns off.

I recently had problems with my Flip camera not working, and I found that when I plugged it in overnight that it fixed the problem. I think this was because I wasn't using the camera for a long time and the battery just died out.

Incidentally don't just plug it into the computer, plug it into a USB hub or wall charger. Most computers will power down after several hours of inactivity and the flip won't get charged.

It's worth a shot to see if that might fix your problem. If this doesn't, you may want to consider upgrading to a different camera. The GoPro series seems to be the perfect subsititute for the Flip camera. Also the iPhone 5s might be a good solution too.

Pingback and Trackback

Some useful information on how Pingback and Trackback work. Might be useful for non-technical people to understand how theses work:
 
A basic explanation on how Trackbacks work:
  • Kim Kardashian writes something on Vistaprint her blog.
  • A fan wants to comment on Kim's blog, but wants his own readers to see what she had to say, and be able to comment on his own blog
  • The fan posts on his  own blog and sends a trackback to the Kim's blog
  • Kim Kardashian's blog receives the trackback, and displays it as a comment to the original post. This comment contains a link to the Fan's post   
              
A basic explanation on how Pingback works:
  • Madonna posts something on her blog.
  • A fan posts on his own blog, linking to Madonna's post. (This automatically sends a pingback to Madonna when both have pingback enabled blogs.)
  • Madonna's blog receives the pingback, then automatically goes to the Fan's post to confirm that the pingback did, in fact, originate there.

Microsoft Outlook Message

Microsoft Outlook Exception

Today I encountered the above dialog in Microsoft Outlook 2010 when I was extending a meeting recurrence. This dialog box really confused me and almost prevented me from extending the meeting.

Why would exceptions be thrown? More importantly, shouldn't I know about them, in case I don't want to extend the recurrence of this meeting.

I get it that Microsoft wants to be helpful by showing the dialog box, but I think that they would have added more value to end users by telling me why Exceptions would be thrown and not just automatically ignore them.

Developer Tip: Don't just tell me that an error might be thrown, show me the error and allow me to take action on that.

Windows 7 unable to access Facebook

This weekend I was trying to debug a Windows 7computer that was not able to access certain websites, such as facebook.com, nytimes.com and cnn.com. This only happened to the desktop computer and no other computer on the network. When I tried ping nytimes.com on the desktop computer, this is what I got:

Pinging nytimes.com [170.149.168.130] with 32 bytes of data:
Reply from 144.24.124.100: Destination host unreachable.

I searched around online but didn't see anything that would help. I checked the virus status, using SpyBot and Microsoft Malicious Software Removal Tool and they didn't find any issue. The host file, and Firewall connections did have any IP address or websites blocked. Nothing came up as the root of the cause. There's nothing in the Event Logs that would explain why the site was blocked.

I also cleared all the cache files from all the browsers, Firefox, Safari and Chrome and it didn't make any difference.

I even tried resetting the TCP/IP stack, as per suggested by Microsoft:

ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int reset all
netsh int ip reset
netsh winsock reset
REBOOT

One thing that I did notice when I used Fiddler2 was that when I would try to access facebook.com, it would hang at fbstatic-a.akamaihd.net. There's no logical reason to why this is happening.

I am still looking into the cause, but one interusting bit is that when the computer was taken to Best Buy's Geek Squad, they had no problems accessing the Facebook sites. Which is weird, because this issue is specific to this computer. No other computers on the network encountered this problem.

The search goes on. One possible solution would be to install Windows 8, but we're not sure if that would really solve the problem.

Wallpaper

Here's a cool trick if you have 2 1920x1080 monitors and looking at wall papers. Look for a panoramic wallpaper, something like 4912x1080 and use that as a background. What's cool is that the image will split between the two monitors. This will only happen if you have the picture position set as Tile. If you use any other selection, the image will not cross over to the other monitor.

You can find lots of really cool Panoramic pictures using Google Picture Gallery or Bing Picture Gallery. Also check out other image search galleries such as Yandex, which recently passed Bing to become the 4th largest global search engine.
