Thanks for the suggestion Zvone. Pretty good as a code editor for the PHP language.

Excellent article! Thanks!

You're welcome Cooleeman.

Great list! Btw have you seen outliner ? It's more minimalist compared to Thinklink but also has a mobile version for iPad & iPhone.

by Jojo Yee on 15. December 2010 - 15:15  (62561)

Thanks Kaspars for mentioning Knowcase, which is now added to the list.

There are many online operating systems or web operating systems in the internet.

Could you include them?

by Jojo Yee on 31. October 2010 - 1:38  (60499)

Thanks Connor for the feedback. Currently we have included Glide under the category of "Desktop and GUI" > "Web Desktop". There might be more such as Icloud, EyeOS and others. Please share with us if you would like to recommend a good one.

Any suggestions for landscaping or outdoor space design?

by IvanDurakov (not verified) on 27. September 2010 - 22:07  (58540)

Any chance of adding some kind of revision marks to this excellent but rather lengthy page? I can never find what has changed since the last rev.

by Jojo Yee on 28. September 2010 - 14:39  (58577)

That's a good idea IvanDurakov. The items added most recently are now marked with a 'New' icon, and with quick links to the items from the Index Table.

Looking also Desktop Wallpaper Tool (with HTML5 features - Drag & Drop and Canvas)

With Desktop Wallpaper Tool you can quickly create desktop wallpaper. Simply load any image and it will be automatically adapted to your screen resolution. An image is adjusted either by cropping the part of it or by scaling, if the resolution of the original image differs from your desktop resolution.

And Slideshow Player for show pictures and photos of professional digital artist from Digital Art Gallery

All scripts based on Prototype

That's a good suggestion, thanks igornevsky.

Minor complaint:

It would be good to add a hyperlinked index for a short table of contents (ToC) at the start of this page, using only the section or category titles. This would provide readers a quick way of knowing whether there are any categories of interest for each reader, while also making the page's listings easier to use for everyone.

by Jojo Yee on 10. September 2010 - 14:14  (57590)

Thanks Mike for the suggestion. In the Index Table, the category titles, when clicked, serve as a tool to expand or collapse a sub-table of a category. The first line in each sub-table is a category hyperlink. Give it a try if that works.

by mikecorbeil on 10. September 2010 - 16:24  (57591)

I don't see an index table, the categories are all fully expanded, and when I click on the title of each category, nothing happens. When I passed the mouse pointer over the first couple of category or section titles that I checked, the pointer changed, but clicking on the title does nothing.

Clicking on "Quick Select Links (After clicking a link, use your browser's Back icon to return here.)" also does nothing.

Found the problem, partly:

I just tried loading this page in Maxthon2 and it seems that the problem is with Firefox. I updated to v3.6.9 this week. Might 3.6.9 be the problem, or is it something else about Ffx, or maybe an add-on? If an add-on, then I don't have a clue which one it'd be, because none of the add-ons that I have installed should cause your index to not appear.

Maxthon2 shows the excellent index that you're talking about and the links work as they would be expected to.

[Moderator's note : Unnecessary list of add-ons removed.]

by Jojo Yee on 11. September 2010 - 0:59  (57615)

Probably you need to wait for the page to be fully loaded before the category links appear. If the page stops loading half way, you might need to refresh it.

The Index Table is using a node feature comes with the CMS Drupal used by this website. I've this page worked perfectly on Firefox, Chrome and IE, and I believe it works for other browsers too.

by Anupam on 11. September 2010 - 16:14  (57655)

Jojo, after Mike posted the comment, I too noticed that the index was not showing for me on Firefox. I disabled AdBlockPlus, for the page, and the index was visible. Any work around for this?

by Jojo Yee on 12. September 2010 - 0:26  (57673)

I tried it on FF3.6 and FF4, both with AdBlockPlus 1.2.2 addon. They showed up the index table nicely for me. Can it be something to do with your filter list?

by MidnightCowboy on 11. September 2010 - 17:32  (57659)

Yeah, use IE :D

by Anupam on 11. September 2010 - 18:00  (57662)

LOL. Pffftt.. neva! :D

by mikecorbeil on 10. September 2010 - 18:36  (57585)

Another online alarm clock is and a user can set the alarm to go or sound off as a rooster, a classical or old-fashioned ringing alarm, an electronic beep, Slayer Guitar (like rock), or military trumpet. I usually use the oldest alarm clock sound, the rooster or cockerel, but wouldn't mind the Slayer Guitar one, if it was James/Jimi Hendrix (often spelled Jimmi). :)

by Jojo Yee on 11. September 2010 - 1:00  (57616)

Good suggestion. Thanks Mike.

For Best Free Screen Capture Utility, you couldn't get anything easier than Snipping Tool, built right into Windows 7. Highly recommended!

Re Time Zone Genius: Doesn't recognize Salt Lake City and Adelaide, two cities important to me. Then if you start to search by country, it shows only four states in the US! Far better is WorldTimeServer at

by Jojo Yee on 24. August 2010 - 9:05  (56622)

Thanks for the feedback and good suggestion.

[Update: just added and hope that you'd find it better. In addition to the main list, a search box is available for entering a city name at the site.]

One last suggestion, I don't want to take over the comment section...
for Best Free Bookmark Manager:
While having less users than, it has far superior features that I think everybody should be aware of.
Diigo has the same "social" functions as but additionally enables you to highlight text and even create sticky notes right on the website, to share or save your bookmark with a personal touch. You can always choose between private or public mode. You can also choose to see the public sticky notes of other users while on a site if you want, a potentially very helpful (or spammy) feature, similar to Google's Sidewiki. A snapshot of the site is taken, so you can still view it even if the page is offline/removed. A new feature is the ability to save frames/images, and take screenshots of any shape and edit them right on the page.
It's an extremely well designed service and integrates nicely with Firefox (bookmarklet, toolbar and combined Google/Diigo search engine).
