Access multiple Google Calendars from KOrganizer
Posted on June 11, 2011
Recently, a question came up on the KDE Community Forums regarding the use of multiple Google Calendars with KOrganizer. The preferred access up to now has been with googledata Akonadi resource, however that doesn’t support more than one calendar, and (at least from my unscientific observation) seems to be rather unmaintained these days.

Luckily, not all’s lost. Akonadi recently gained the opportunity of accessing CalDAV resources, and Google Calendar also offers a CalDAV interface, hence this is possible.
This post will briefly describe how (thanks go to PIMster krop, which casually mentioned the possibility on IRC and prompted me to investigate).

Notice: I am running trunk (4.7) so I have no idea if the steps posted below are possible in 4.6. Also, this worked for me with my particular setup. YMMV.
First of all, you need to obtain the calendar IDs you want to use. This is done in the web version of Google Organizer, in the settings page of your specific calendar, near the private links: it’s a string of alphanumeric characters followed by @gmail.com. Copy it in full (even the address part) as you will need it later, and do it for every calendar you want to use.
Next, open KOrganizer, locate the list of the calendars, right click on an emtpy spot and select Add Calendar:

In the next screen, select “DAV Groupware resource”, then a wizard will come up. Fill in username and password (apologies for the language! I haven’t found a quick way to switch these dialogs to English) and click on Next:

In the following screen, choose Configure the resource manually:

Click on Finish, but you’re not finished yet. In fact, we will have to add more stuff here. In the new window, select the display name (here shown as Nome visualizzato) of the calendar, then click on Add (which is translated as Aggiungi in this screen):

In the next screen we’ll have to add what’s needed for our calendar to work. In Remote URL put https://www.google.com/calendar/dav/YOURCALENDARID/events (https, not http) then put (again) your Google account credentials in the relevant places. Then click on “Download” (Scarica here) and you will see (after a while) your Calendar being loaded in the “Found collections” pane, with the name you set in Google Calendar. Click OK to save the configuration.

This will bring you back to the previous window. For more calendars, repeat the steps (click on Add, insert URL, Download, OK) for all the calendars you have to display.
That’s it. If you encounter trouble, have a look at ~/.xsession-errors to see whether Akonadi managed to connect and download your existing items correctly. And don’t forget to file bugs!

Opera 10.5 Beta Adds Private Browsing and Excellent Windows 7 Integration [Downloads]

Standard

Windows only: The latest beta version of the Opera browser adds total Windows 7 integration, with Jump Lists, Aero Peek, and a beautiful Aero Glass interface—and we’ve got a quick tour of all the new features.

The first thing you’ll notice after installing the 10.5 beta is that the interface has been completely re-done with Aero Glass for Windows 7 or Vista users. The menu bar has been rolled up into a single button similar to the way Office 2007 works, with easy access to all common functions all from one place.

Windows 7 users can now hover their mouse over the taskbar button and see previews of each of the open tabs, and moving your mouse over a specific tab will enable the Aero Peek effect and show the Opera window with the contents of that particular tab—just the way Internet Explorer 8 does. You can even middle-click on the thumbnail preview to close a tab.




The Jump List menu shows the items from your Speed Dial, lets you open a new tab, or start a new private browsing session in a separate tab. Once you’ve opened a new private tab—which you can also do by right-clicking on the new tab button on the right of the tab bar—the icon in the tab will change to indicate that you are in a private browsing session.

You can choose to open a separate window for private browsing, but being able to include that private tab without requiring a new window is a nice feature that you can’t currently do in any of the other mainstream browsers.

Opera 10.5 beta is a free download for Windows only; Unix and Mac builds will be available later this week.

Avast Free Antivirus 5.0 Adds Behavior Monitor, Heuristics Engine, and Improved Performance [Downloads]

Standard

Windows only: The newest version of the popular Avast Antivirus is finally available for download. It’s lighter, faster, and more feature-filled than ever, bringing a new behavior shield, heuristics engine, and code emulator to keep you protected at all times.

Apart from its far easier-to-navigate interface, Avast has a few new features that make it hard to turn down. Its new code emulator can emulate a suspicious executable’s code, isolated, for use in its new heuristics engine, designed to detect malware that would otherwise be undetectable with normal definitions—in other words, spotting malware by learning what the code does. If you use the pro version, you also get their new sandboxing feature for even further protection.

Apart from the new features, Avast has also lowered scanning times as well as the resources necessary to scan and update—a common issue with antivirus programs that are always running in the background. If you’re already an Avast lover (and many of you are), you can either wait for the program to update itself in the near future or go download 5.0 straight from Avast. If you’ve tried Avast and turned it down before, it may be worth another look—you may find that its former cons (such as the difficult-to-use GUI and resource use) are now more up to your standards.

Avast Antivirus is a free download, Windows only.

Build a Wall-Mounted Kitchen Computer [DIY]

Standard

If you’ve been dreaming of having a computer in your kitchen but don’t like the idea of hanging it from a cabinet or having it clutter up the counter, this guide can help you build a sleek in-wall computer.

Putting a computer in your kitchen and having it look natural and part of the design is a big challenge. Ryan’s wife had been bugging him to put a computer in the kitchen so she could use it to access the internet, manage recipes, generate shopping lists and so on. She also had a pretty tall order when it came to the machine, she wanted it to be discrete, have a touch screen, be internet-enabled, with wires hidden and equipped with a barcode scanner for her to scan products and manage a kitchen database. Not dissuaded by such an ambitious list, Ryan set to work and built an in-wall computer that looks like it was designed and installed by a professional.

The build sports a touch screen, runs Windows XP with an interface cloned from the iPhone for easy finger-based navigation and use, and can do everything from displaying the weather to organizing the pantry. You can check out his build guide for detailed information including how he created the iPhone interface from scratch using the active desktop feature in Windows and coding a custom web page using icons he made and linking them to online services and software on the computer.
