Street View, a cool feature from Google Maps

Google MapsHave you recently used Google Maps? Maybe you already noticed its new feature from the maps, yes, it is called Street View. What can it do? well, when you browser the maps (of course, on the website of http://maps.google.com) and click the Street View button on the map. You will see a little man icon on the map, and some street view photos will appear when you drag “you” (the little man) on some blue line highlighted roads. These photos just like what you can see when you walk or drive on the road of the Google maps.

Yahoo Opens Search Technology To Third-Party Search Engines

By Scott Morrison
Of DOW JONES NEWSWIRES

SAN FRANCISCO -(Dow Jones)- Yahoo Inc. (YHOO) is hoping to boost revenue and steal market share from rival Google Inc. (GOOG) with a new plan that opens its search technology to third-party developers who want to build their own search engines.

The initiative lets partners tap into Yahoo’s back-end search technology - the algorithms and infrastructure that power its search engine - as a Web service, but allows them to control the presentation and ranking of the search results. Those partners, in return, would be required to run Yahoo search ads on their pages, with the two sides sharing revenue.

The Sunnyvale, Calif., company announced the program, dubbed Build Your Own Search Service, or BOSS, early Thursday.

How to disable/remove/uninstall incompatible add-ons in Firefox

firefox-extensions_thumbnailJust wanted to explore some add-ons after I installed the final version of Firefox 3.0 today. I found this add-on named TwitterFox in Get Add-ons Tab after I clicked Tools –> Add-Ons option. Excitedly installed it since I am using Twitter accounts now. But after the TwitterFox installation, my firefox 3.0 acted very wired. I could not bring the Firefox screen focused. It always hid in the taskbar, and the left/right click of my mouse did not even work at all on FireFox in the taskbar.

Official Firefox 3.0 download site is down

I really tried to help Mozilla to make the Guinness Record for the most downloaded software within 24 hours. But unfortunately the poor preparation of Mozilla made it very difficult for me to even get on the website. I tried from 1:40pm (Eastern time, 40 minutes after the official release time) to 2:40pm and could not connect to the website. I am sure it was because too many people were connecting to the website at that moment, but Mozilla should have known better before it put such statement as Make Guinness Record on its website to promote Firefox and lure everybody.

I put some available screenshots below and hope the poor website will be back soon.

Mozilla Error

Mozilla.com which hosts Firefox and Thunderbird was down with “Service Unavailable” error message

Firefox Guinness

And the FireFox could not connect to the download page of Firefox 3.0 on Spreadfirefox website

Finally, I even tried the Firefox Check Updates… feature and no luck at all.

[Updated: the website is back now, it is not too late to download the firefox 3.0 and make the Guinness Record now before 18:00 EST 6/18/2008]

But the final build of Firefox is now available for download on the FTP server. I could not resist and already grabbed my download and installed. (I will download again as soon as its official release becomes available because my downloading will help Set a Guinness World Record for the most downloaded software in 24 hours)

IMPORTANT: Downloads from FTP server and direct links will not count towards the Guinness World Record attempt for the most software downloads in a day. If participation in this event is important to you, wait for the official release.

Make a free auto get/put files schedule with FTP scripts in DOS environment

Challenge:

msdosI need to pull over a file from our FTP server every minute to the database server. I do not want to install any FTP schedule utilities on the database server. So I decided to use the FTP.exe comes with the Windows server OS. I brought up a DOS prompt, type FTP and hit Enter. I got some prompt screens, what I needed to do is to provide the remote server IP (host name) and user credential information. After I logged on, I then can use some UNIX like commands as LS and GET to download files. Great, it approved that we really do not need a fancy FTP client program.

But how can I make the above process automatically, since I could not put user logon credentials into a DOS batch file.

Research Results:

To overcome the challenge above, I need to come up an FTP “script” which can work together with FTP in DOS, since FTP.exe supports scripting with the “-s:” option.

For example, if your plain text FTP script file has a name of FTPSCRIPT.TXT (assume you put the same directory as you type your DOS command), then you can use the following command to execute FTP script:

ftp -s:FTPSCRIPT.TXT

Can not start a workflow from a survey response in Windows SharePoint Services 3.0 (MOSS 2007) with "Failed to Start" error

Challenge:

sharepoint When I was approached by a co-worker to come up a quick solution to design a training registration application. The requirement is to display all upcoming training events in calendar view and allow users to register to each training. And upon the registration is submitted, the training department and the user’s supervisor should receive notifications immediately (although not required now, but might need the approval from the supervisor in later development). The deadline is very…, how to say it, … how about this afternoon. Well, while the co-worker asked how to design the database tables and asp.net coding, I suggested why not giving the SharePoint a shot. Since I am the one proposed, then I had to create it for her.

Well, that was what I came up so far. In our Microsoft Office SharePoint Server System (MOSS) 2007 with Windows SharePoint Services 3.0 (WSS), I created a calendar list to display training events; in the calendar item there was a link to another new created survey list acting as a registration form. Then I added a workflow to the survey so that emails will be sent out whenever a new response is added into the survey (or register list).

Everything is working fine, but however, the workflow does not start. Instead, the status of the workflow appears as Failed to Start.

Trouble-Shootings:

I searched this issue on Google, and I found out a lot of people had the similar errors before. Someone pointed out the cause was the user of application pool who should be Network Services instead of a user with administrative right; Someone suggested to re-active the workflow feature in SharePoint Application server; Someone asked whether it was done in SharePoint Designer  2007.

Fix RIM BlackBerry 8703e "JVM Error 523"

blackberry_8307e Challenge: Today when I tried to browser a website on my BlackBerry 8703e, it all of the sudden frozen up and then showed a white screen with "JVM Error 523" in the middle after a self-reboot.

I tried to scroll down and clicked the Reset link under the error message, but nothing happened. I could not even do a power off reset, since the Power button on the top was basically non-responsiveness.

So, I opened the back cover and took out the battery, and then I put back the battery. Yes, I could see the desktop after the boot-up and even the message of "verifying security software…". But unfortunately the blackberry immediately went back to the White Screen with the same "JVM Error 523". At that point, the device is totally useless, since none of any buttons on the blackberry was functional.

Cannot use right click or drag/drop of mouse in Microsoft Word and Outlook 2003

Word_Icon_A Today I tried to copy and paste an email in Outlook 2003 but found out the SELECT ALL function of my mouse did not work. I could not highlight any texts in the mail body, and I could not even see the copy & paste options and the whole context menu by right clicking my mouse. 

Since I know I configured in the Outlook to use Microsoft Word 2003 as the primary email compose tool, I opened a new Word Window to see how things do in the Word. Same thing happened in Microsoft Word 2003, I could not use all my mouse right clicking.

Ubuntu 8.04 installed (with pictures)

ubuntu804 As its previous versions, the newer version of Ubuntu (version number 8.04 and code name ) is very easy for the installation. After downloading the ISO file from the Internet and pointing it with one of my virtual machine, the installation menu was there quickly. With its no-brain 7-step installation process, the overall time was less than an hour ( I got some issues with my virtual machine, but it was still cool compared with couple of hours with Windows OS installation).

Read on for more installation photo gallery… You can click the thumbnail to view the larger picture.

A very good Chinese Airline ticket price comparison website

Smart consumers in USA will go to price-comparison websites (Such as expedia.com, sidestep.com,  travlocity.com etc. ) to find good deals on airline ticket, hotel price before their trips. Sometime, we can find good International travel deals on these websites as well. But as for the airline ticket pricing information for Chinese domestic travel, I would like to use some Chinese websites. One of them I like most is Qunar.com whose name means "Where are you going?" in Chinese. It is a search engine which can search prices from most travel (airline tickets, hotel) service providers’ websites based on your search query, and then filter, sort for you. Then you can purchase such services by clicking the links in the search result (sounds more like sidestep.com).

Based on my recent uses, the prices on the search result is the best price I can find on the Internet. So I recommend this web site to you if you are going to travel in China cities next time.

Good Overseas Travel calling plan - Using MagicJack to call back home

I will stay in China for a while and have to contact back to my family and co-workers. Using traditional phone plans is not a good idea, I know China Telecomm is overcharging international calls as much as they can. I am glad that I can install a broadband at home here very quickly and cheap (RMB 660 like $90 for a whole year), and glad that I brought my MagicJack with me as well.

After the Internet broadband installation, the first thing I did was to connect the MagicJack to my Laptop’s USB connection, and let the Jack automatically run the software installation. Since this MagicJack has been registered and activated by me in USA before, the whole installation process here is very simple. The only holdup is the downloading time due to the bandwidth from the ISP I am using.

After the completion of installing MagicJack software, I heard the dial tone when I plug a normal phone set to the MagicJack. And I dialed a USA phone number, and I heard the phone on the other side ringing. Then I asked my family test from USA, they just dial a local number (I registered for my MagicJack) and the phone connecting to MagicJack ring. I pick it up and then I can talk to them in North America for free from China now. (Of course, I already paid $19 a year for the MagicJack)

How to get back the Internet Online Stream Radio by uninstalling Windows Media Player 11

Windows Media PlayerWho loves listening to Internet Radio while you are working or coding? Yes, it is me. I like Internet Radios, and that is why I think the Internet is so great. Since I like music, especially listening Chinese songs while I am coding to stop the outside world from interrupting me at that moment, I sometimes use online stream radio to enjoy the no-stop new/old music playing because the traditional radio wave can not cross the ocean for me.

But suddenly I could not connect to some of my favorite Internet Radio stations any more, name a few, Taiwan Kiss Radio, etc. This made me very frustrated, since I could not be focused on coding without radio music. But the trouble shoot for this issue made me more frustrated. I tried to close all my anti-virus, and google search on “can not listen online radio” return invalid solutions.

After a few days of listening to CD music, I figure out the problem was caused by one of Microsoft’s recent updates. MS just upgraded my Windows Media Player from version 10 to version 11. And for no reason, starting from Windows Media Player 11, it does not support mms:// protocol any more. And a lot of radio stations are still using mms:// instead of rstp:// protocol.

I know it is so stupid for doing such thing on a so-called popular stream audio/video player. But hi, it is MICROSOFT. What is the difference of rstp:// and mms:// anyway.

OK, to get back my Internet Radios, my only choice is to un-install Windows Media Player 11 and use the previous version of Media Player (Unfortunately all of my favorite online radios do not use Realplay stream format, it is sad).

Do you want to get paid for your interview?

On the web, there are a lot of new ideas coming up everyday. Yesterday, I heard about that there is a web to pay people for their interviews. According to Clark Said, now a website allows you to name your interview price. Since this website believes that it is cheaper for employers to pay targeted candidates to interview than to wade through a ton of unqualified applicants.

Here’s an odd one for the job seekers among you. There’s a new website that pays you to go on interviews. So far only technology-geared companies are making use of NotchUp.com, which is in beta. Here’s the scoop: It’s very expensive for companies to use classifieds and online job sites to find new employees. NotchUp.com, however, is free to employers. They find it’s cheaper to pay targeted candidates for their interview time than to go the traditional advertising route and have to sort through a ton of unqualified applicants. Will NotchUp.com be around a year from now? Who knows! But if you’re seeking a new position, pursuing this opportunity can’t hurt you. …..
