Windows 7 : Reasons not to upgrade

Cyber Cynic Steven J. Vaughan-Nichols has come up with a list of seven reasons not to upgrade to Windows 7. Here's his list (in brief);

1) Windows 7 still has all the security of a drunken teenager in a sports car...

2) Windows 7, no matter how you buy it, is expensive. Does your budget have the extra cash to buy a new and improved taskbar!?

3) Upgrading from XP to Windows 7 will require that you do a clean install. That means everything on your hard disk gets vaporized during the 'upgrade.' ...

4) You'll need to reinstall your old programs and device drivers. Then, you'll need to update all those programs and drivers. Doesn't that sound like fun? Doesn't that sound like hour after hour per PC of migration work?

5) XP already works ... I'll be darned if I can think of a single, significant change that you'll get from running Windows 7 instead of XP.

6) If you're an XP user you'll need to learn a new user interface. ... if I'm a CFO or CIO, I want to know what I'm going to get out of re-training people to the new interface and I'm left thinking there's really nothing game-changing about the Windows 7 UI.

7) Finally, if you have an older PC, forget about it. I know there are people who swear that Windows 7 will run on low-powered PCs. Yeah, right. I've used Windows 7 on netbooks. It wasn't pretty.

Bottom line. If you want something that's really better than XP, and you're willing to go to the trouble and expense of moving from one platform to another, you'll get real improvements like better security and low up-front costs, from a desktop Linux like SLED (SUSE Linux Enterprise Desktop) 11 or Ubuntu 9.04. Windows 7 is certainly better than Vista, but XP... not so much.

Check out the link above for the full details. And by the way, Ubuntu 9.10 is out today ...

Hidden Linux : Learning to love KDE 4 (part III)


To conclude this mini series on KDE 4 I'm going to let you on a few tips and tricks I've picked up in the course of my explorations. Note that all comments apply to Kubuntu 9.10 and KDE 4.3. You distro mileage may vary!


Desktop Search
"Pervasive searching" allows you to search the contents of your files in the same way that Google searches the contents of websites but activating Nepomuk and Strigi in System Settings / Advanced / Desktop Search didn't do anything for me, so I searched out the answer and found it here. After a few straightforward tweaks Nepomuk started indexing ...




Task Manager Tweaks
Task Manager isn't just cashew-controlled. Right-clicking on it gives you a even more settings, amongst them the ability to group, sort and stack open tasks so, for example, instead of this ...


you can have this ...





Plasma and Panel Themes
Want to change your Desktop theme? Don't go to System Settings / Advanced / Desktop Theme Details! Yes, yes, I know it's got a button to Get New Themes but it won't do you any good. You can add new themes, you can select them but you simply can't apply them. I wasted ages trying to figure out why Apply stayed greyed before finally discovering the place to go is Desktop Settings under the desktop cashew.

Don't go here ...


Go here!




Krunner Kraziness
Krunner -- invoked by hitting Alt + F2 -- is a quick and useful way to kick off programs but it has a ton of other functions too. You'll start to get the idea if you click on its Settings button ...


Amongst other things you can use it as a calculator ...


... a unit convertor ...


... a website launcher ...


... or simply click the System Activity button to see what's eatiing your CPU.


But wait, there's more! Add the plasma-runners-addons package and you'll get spell-checking, contacts lookup and assorted other goodies.



Zooming Desktops
Linux has had multiple desktops since Adam was a cowboy but under KDE 4 you can have multiple-multiple desktops. Confused? Bear with me ...

Start by setting just one desktop under System Settings / Desktop / Multiple Desktops. Now click on the desktop cashew and choose Zoom Out. You'll get something like this ...



Note how that central menu conveniently covers half the window controls making it impossible to zoom back in! Nice. (Actually, the trick is to click and drag on the background. You can move it around that fixed central menu so you can get back out. Phew!)

On the central menu choose Add Activity. Pow! A new desktop appears.



You can now zoom in and configure this one with whatever settings and widgets you like, completely independent of the first desktop. I find this great for switching to a widget-free workspace but going backwards and forwards via the cashew / Zoom Out / Zoom In route is a pain. And the shortcut (under cashew / Shorcut Settings) doesn't work on Kubuntu either so I configured my own:
  • Click the cashew and choose Shortcut Settings.
  • Find Next Activity and click the arrow head under the Alternate column.
  • Select Custom, click the None button, then hit the keys you want to use. (I chose Meta + RightArrow.)
If you don't like shortcut keys, add the Activity Bar widget (cashew / Add Widget). That'll put a mouse-clickable activity bar on your desktop, but forget to put it on both!

(Of course you don't have to restrict yourself to a single desktop to for this or even a single activity. I've just done so to make this illustration a little clearer.)

That concludes this three-part tour of KDE 4, but if you have a favourite tip or tweak I'd love to hear it. Maybe we could do a Part IV!

Toolbox: Roadkil's Unstoppable Copier


Digging around on an ancient home-burnt DVD I discovered a couple of large video clips that simply weren't readable -- in any of my three machines -- and of course they were the very clips I wanted. I covered recovering audio CD data a while back, but what about DVDs?

A quick search turned up Roadkil's Unstoppable Copier, a free program that claims to recover files from disks suffering physical damage.

The program will attempt to recover every readable piece of a file and put the pieces together. Using this method most types of files can be made useable even if some parts of the file were not recoverable in the end.

Test #1 was on a file from which I could only copy or play the first half. That went brilliantly. In fact it took Unstoppable Copier only a few minutes to recover the whole thing. Woot!

Test #2 was more taxing. The file showed on the directory but there was no way to so much as get a look-see at it. This took all night but by morning it had been recovered. There are one or two glitches in the video where data is apparently gone for good, but they're easily editable and it's relief to something back!

And the other good thing about Unstoppable Copier is that it's available for Linux, Linux 64-bit and all flavours of Windows.

Hidden Linux : Learning to love KDE 4 (part II)


The main difference between KDE 3 and KDE 4 is that the former is fixed and static while the latter is dynamic and interactive. For a trivial example of that go to System Settings / Desktop / All Effects and activate Snow. Now hitting the Meta+Ctrl+F12 keys (or Win+Ctrl+F12) will fill your desktop with falling snowflakes.

KDE 3 always displayed the contents of the user's Desktop folder on the desktop but in KDE 4 you can use plasmoids to display any containment on Plasma. Say what? Yeah, that's part of the problem: KDE 4 has a whole new lingo.

OK, let's start with the basics.



Plasma is the screen you see when you start KDE 4. It includes the panel -- that's the task bar running along the bottom -- the Plasma toolbox -- the thing up in the top right-hand corner that looks like a cashew nut (it's also known as the cashew), and in the example above a containment -- the shaded translucent area displaying the contents of the user's Desktop folder.

Perhaps a more practical example of KDE 4's desktop dynamism is that it doesn't just restrict you to displaying the contents the Desktop folder. You can display the contents of any number of folders, even networked ones, and changes to them are displayed in real-time. If you run an automated daily backup for example you can open view of the server's backup folder to provide a handy visual check that everything's working as expected.

The other major feature of KDE 4 are its widgets and plasmoids, which are almost one and the same. Widget is the generic term for any small application that directly manipulates specific data. They may come from a variety of sources such as Google Gadgets and the Mac OS X dashboard.  Plasmoids on the other hand are Plasma-specific widgets native to Plasma itself. Here's a widget/plasmoid that displays network activity ...



... and here's one showing the weather forecast ...


(Yes, I know it's tilted. You can position and resize widgets any way you like!)

Add widgets by clicking on the cashew and choosing Add Widgets. Then just drag-n-drop to the desktop. If you want to find more, click the Install New Widgets button at the bottom of the Add Widgets window and select Download.

What sorts of things get widget-ised? All sorts of things! At the time of writing the highest rating widgets included a notifier that sits in your panel telling you how many unread messages are in your GMail account, a plasmoid to stream audio from the internet, a Facebook viewer, and one for send fast SMS via a Greek mobile provider! And heres some more cool ones.

But what use are all those widgets if you can't see and monitor them when you apps are full-screen? Easy. Ctrl+F12 toggles the widget dashboard, darkening your application and bringing them to the foreground.

Almost everything's a widget in Plasma, including the K menu. If you don't like the Kickoff or Classic menus, try something different. Lancelot's very popular. And because it's a widget you can run it alongside the K menu to see which one you prefer.

In short, Plasma and KDE 4 allow you to build your own interactive desktop. If that seems a little daunting, check out what others have done ...















You'll find even more here.

Hidden Linux : Learning to love KDE 4 (part I)


There seems little doubt that KDE 4, the flagship desktop environment used by many Linux aficionados, was released too early. After seven years of solid, steady KDE 3 deployment, KDE 4 was released amidst the much media hoopla and near-universal user disappointment. It simply wasn't ready for userville. There was too much missing and too many differences; it felt like a retrograde step. To be fair, the KDE team did describe it as a work-in-progress, and some of the fault lies with distro packers who slapped essentially beta code into their latest releases. As a result many users simply avoided it. Including me. At least until recently.

Since its ill fated inception in November 2007 KDE 4 has undergone a number of significant upgrades. Version 4.1 came out in July last year, 4.2 in January this year, and for the last month I've been working with version 4.3 which was released in August. I reckon KDE 4's now ready for the big time, and with Kubuntu 9.10 ("Karmic Koala") due shortly, it's time to throw off the shackles of KDE 3.

Moving from 3 to 4 is a big shift. There's lots of new stuff and many unfamiliar concepts so to start with I'm going to show you how to make it all look familiar. We're going to make KDE 4 look and act like good old KDE 3. That way you can ease into the new environment without losing productivity.

(Note 1: The following discussion ignores all the new stuff for now. We'll get to that next time!)
(Note 2: If you're already running KDE 4, I strongly recommend upgrading to version 4.3!)



Menus
The new menu style is known as "Kickoff". If you want to make it eff-off and go back to the traditional K Menu, simply right-click the K button and choose Switch to Classic Menu Style. Right-click again to switch back to Kickoff.





Desktop icons
The absence of desktop icons has caused no end of concern. By default they're replaced by a "containment" -- a semi-transparent window displaying the contents of the Desktop folder. (We'll talk about some of this new terminology in Part II.) To get your icons back, proceed as follows;
  • Move your cursor into the containment and a handle will appear, either to the left of right of it.
  • Click on the X to make it go away.
  • Now right-click a blank area of the Desktop and choose Appearance Settings.
  • Under Desktop Activity click on the Type droplist and select Folder View.
  • Click OK.


Adding icons to the Desktop or Panel
To do this you first need to switch to the Kickoff menu style. (See "Menus" above.) Then you just navigate to the desired application, right-click it and choose Add to Desktop or Add to Panel.



Modifying the Panel
The bar at the bottom of the screen is officially called the "Panel". To modify it, right-click in an unused area and choose Panel Options followed by Panel Settings. This will open an extra GUI. with extra controls.



The arrowed sliders immediately above the Panel allow you position and size it horizontally. Click and drag Height to adjust its height. If you want to move the Panel to the left, right or top of the screen, click and drag on Screen Edge. And you'll never believe what's under the More Settings button. Yup, more settings including auto-hide and how windows interact with the Panel.

You can also reposition things on the Panel by hovering your cursor over them and left-clicking and dragging when the four-pointed arrows appear.



Defaulting to Konqueror
If you don't like Dolphin, KDE 4's new default file manager, you can switch back to Konqueror like this;
  • Hit the K button and open System / System Settings. (Or Computer / System Settings if you're using Kickoff.)
  • Choose Default Applications, select File Manager and click Konqueror.
I prefer the Details view as my default but until KDE 4.3 there was no way to lock this in. There is now though!
  • Choose View / Adjust View Properties.
  • Choose Details from the View Mode droplist.
  • Under Apply View Properties To select All Folders and tick Use as Default for New Folders.


What the hell happened to ...?
* KControl now has a more meaningful name: SystemSettings. (Or "systemsettings" if you want to run it from a console.)

* KCron is now part of System Settings. Choose the Advanced tab and click on Task Scheduler.

* Ctrl+Alt+Backspace to restart the X server is disabled by default. You can either use the more awkward Alt+SysRq+K combination or type sudo dontzap -d in a console window to re-enable it.

* Compiz is still around but you might like to check out Desktop Effects under System / System Settings / Desktop first. (I particularly like the Fall Apart option for closed windows ...)



In the next part we'll explore some of KDE 4s core concepts -- and what makes it different and sooo exciting. Stay tuned!
