How to keep your real email address secret


Mailinator is such a brilliantly simple idea that you'll wonder why you didn't think of it yourself -- and why you haven't been using it for years.

Tons of sites -- and lots of proprietary software -- demand you register first. While you can claim to be an Albanian brain surgeon earning millions of dollars a year, you invariably have to supply a real email address to get the desired registration confirmation or secret activation code. That's where Mailinator comes in.

You just make up an email address ending in @mailinator.com. dropdead@mailinator.com, GetStuffed@mailinator.com, Aaargh123@mailinator.com ... anything you like. To read your email, just go to www.mailinator.com and enter the inbox name you created. No sign-up, no registration and no password required.

Obviously you won't want to use the service for personal or private messages as anyone entering your account name will be able to read them. But that's not the point. Mailinator provides you with a disposable email address that allows you to collect those confirmations and activation codes while maintaining your privacy.

Brilliant and simple!

Hidden Linux : Test Driving KDE 4.1


KDE 4.1 was released at the end of July and you can add it to any Ubuntu installation with a simple repository update. Add is the operative word here. It's basically a no-risk operation since 4.1 will happily co-exist with your current version of KDE or Gnome(or Enlightenment, or Fluxbox, or Openbox, or ...). It's simply a matter of switching display managers at the login screen.

Kubuntu users should add the following repository to Adept Manager (by clicking Adept / Manage Repositories / Third-Party Software). Ubuntu users should select System, Administration, Software Sources from the desktop menu and add it there.

deb http://ppa.launchpad.net/kubuntu-members-kde4/ubuntu hardy main


Install the package: kubuntu-kde4-desktop either via your GUI installer or by running the command sudo apt-get install kubuntu-kde4-desktop in a console. The total download is around 112MB.

For good measure I also added:

gtk-qt-engine-kde4 : a theme engine that gives GTK+ 2 applications a more unified KDE 4 look.

kdeplasma-addons : a collection of additional Plasma data engines and widgets.

kdebase-workspace : to fix a bug when running the KDM-KDE4 display manager. I only added this to try and fix my graphics woes (see below). It didn't work.


The initial result was a sumptuous graphical feast ...


KDE 3.5.9 Desktop (Before)                                              [Click for a larger view]


KDE 4.1 (After)


The graphics are rich, transparency looks great, and Compiz -- which I'd set up in KDE 3 -- transferred across flawlessly. To get an idea of the integration, compare these two views of the Dolphin file manager. The KDE 3 version looks positvely old-fashioned in comparison ...

Dolphin -- in KDE 3 and KDE 4


But I won't bore you with talk of all the new features. Instead, let's talk about the problems.


Kickoff
Kickoff, the new menuing system, looks good and I like the Search facility, but it's actually a retrograde addition since it requires more mouse wiggles and clicks than the Classic menus, and is less intuitive to boot. To start OpenOffice.org Writer in KDE 3 I ...
  • Click the K menu
  • Slide the mouse to Office
  • Slide down to OOo Writer
  • Click on the item

In KDE 4 that sequence is ...
  • Click the K menu
  • Move to Applications
  • Move to Office
  • Click on it
  • Scroll down to OOo Writer
  • Click on the item
A first it looks like this isn't a big deal because switching back to the Classic menu is simply a matter of right-clicking the K button. But caution! Doing this removes some functionality. In KDE 4, the only way to put icons on the panel is to right-click on them in the Kickoff menu. (But they don't seem to stay there! When I restarted 4 they'd all vanished.)


Panel Control
Speaking of Panel, a lot of the old options and functionality seem to have vanished in KDE 4. These are the only options I've found so far ...



... compared with the multi-layered controls you had in KDE 3 ...



In fact there are now so few user-configurable options in Panel I've started calling it ... er ... Gnome.


Dolphin
It looks better and works more smoothly in KDE 4, but I still don't like it. Konqueror is a vastly superior file manager. Fortunately it is still available in KDE 4, but it's hidden away under its web-broswer+file_manager+??? cloak. One of the first things I did was create a separate menu item for it using the ridiculously arcane command string kfmclient openProfile filemanangement then set this as the default file manager


Other Interface Nonsense
Back in January, Insane Coder pointed out other retrograde interface steps in KDE 4. Unfortunately, no one at KDE was listening. They're all still there.


Input Actions
I'm a big fan of using hotkeys to start applications and perform various useful functions, but I've had big problems with 'em under 4.1. They seemed to work initially and then stopped. For good. Even enabling the preset Example set produces nothing. And what happened to the Run command (Alt+F2)?


Screensavers
Where did all the screensavers go? By default you have a choice of Blank Screen or Random -- which obviously means you'll just get a blank screen. Fix this by adding the kscreensaver-kde4 package.


Graphical Desktop Weirdness
The underlying platform seems rock solid but I get a lot of graphical weirdness. With focus on an application like OpenOffice Writer or Kompozer (but not Gimp), dragging the cursor over the Taskbar creates all sorts of weird effects ...


Clock weirdness

... sometimes wrecks the menu ...

Wrecked menus

... and can even screw up the entire desktop ...




None of these are fatal, but they're damned annoying -- and distracting. It surprised me to find this much instability in an upgrade/bug fix version eight months after the inital KDE 4 release. Of course it may be -- and almost certainly is -- something to do with my set up, but until I get it sorted I'll be sticking with KDE 3.

Is NZ ready for a cyber-attack?


An interesting piece in The New York Times links cyber-attacks with the with the recent Russian attack on Georgia.

...in the run-up to the start of the war over the weekend, computer researchers had watched as botnets were ”staged„ in preparation for the attack, and then activated shortly before Russian air strikes began...

Ranking behind Nigeria, Bangladesh, Bolivia and El Salvador in terms of internet use, the effect on Georgia wasn't great:

In the end, Georgia, with a population of just 4.6 million and a relative latecomer to the Internet, saw little effect beyond inaccessibility to many of its government Web sites, which limited the government’s ability to spread its message online and to connect with sympathizers around the world during the fighting with Russia.

That led me -- given our greater reliance on the internet -- to wonder at the state of our own readiness. After all, according to this report, we're number two in the world in terms of hack attacks, and our government domains (govt.nz) are the eighth most popular targets worldwide. So is there an oversight group or coordinating body that would take charge in the event of a concerted cyber-attack on .nz? There's a passing reference to the need to review "New Zealand's cyber security response capability with a focus on government and industry" in April's Digital Strategy, but that seems to be it.

Oh, there is the New Zealand Computer Emergency Readiness Team, "
a registered Charitable Trust established to improve the general Information Security posture of New Zealand society."

So is that all that stands between us a targeted cyber-attack; a charitable trust? (And what the hell is an "Information Security posture" anyway?)

Cyber warfare isn't necessarily a precursor to a military attack, in fact these days it's more likely to be for economic gain. What might a concerted DDOS attack on a small country like New Zealand do to the NZ dollar, for example? As the NYT notes, cyber-attacks are inexpensive, easy to mount and leave few fingerprints so they're bound to become more common. Shouldn't we be prepared?

Hidden Linux : Compiz con-Fusion


In the last Hidden Linux I looked at upgrading to the latest release of Compiz -- that set of jaw-dropping desktop effects available only for Linux. But a regular reader accosted me (in the street, no less!) and reminded me that I meant Compiz Fusion, not Compiz. He's right.

Compiz and Compiz Fusion are related. Compiz is a basic nuts-and-bolts compositing window manager that runs quite happily on its own. It has a number of clever effects built-in -- including wobbly windows and the rotating cube -- and provides a flexible plugin interface for developers to add other goodies.

Compiz Fusion is built on the Compiz core. It came about from the merger of a couple of older projects -- Beryl and Compiz Extras -- and aims at adding functionality to the core components through plugins, tools and libraries. Both projects are still in active development.

That clarified, let me point you to a couple of sites exploring the sillier fringes of Compiz Fusion's plugins. Tombuntu details three experimental plugins, (and how to install them):
  • Atlantis2 adds a customizable aquarium to your desktop cube.
  • Freewins provides the ability to rotate and scale windows in 3D "with fun inertial effects".
  • Screensaver either slowly rotates the desktop cube or zips windows around the screen when while you're away from your PC.

Meanwhile, over on LinuxHaxor, Pavs illustrates what he reckons to be five useless Compiz Fusion effects, among them a burning-windows-while-minimising effect and folding unwanted windows into in a paper plane then flying them off screen.



You can find out more about Compiz Fusion and the main, extra, unsupported and experimental plugins available for it here. You might even want to write your own...

Another reason to secure your wireless network...

After last week's horrific bomb blasts in India, police received an email claiming responsibility. They tracked it back to its sending IP address and promptly raided a Mumbai apartment -- containing not some militant extremists, but a group of bemused American expats with an open wireless network.

In a cautionary tale for those still lax with their wireless internet security, police believe the email about the explosions on Saturday in the west Indian city of Ahmedabad was sent after someone hijacked the network belonging to one of the Americans...       [more]

If you still don't get it, download and install Network Stumbler (it's free) and check out your neighbourhood. I'm amazed at the number of folk who still use unsecured wireless networks -- including businesses!

What are the implications? Well, apart from letting your neighbours (or passing terrorists) help themselves to your bandwidth, anything they do gets logged against your IP address. So unless you fancy high bills or police visits, lock it down! (And please, use a secure password. I recommend GRC's Perfect Passwords generator.)

Incidentally, if you do get picked up by the police, here are a couple of interesting and entertaining video clips (part 1 and part 2) from a lecture on why you shouldn't talk to them without a lawyer -- even if you're innocent!
