Computing UI visionary Douglas Engelbart passes away at age 88

Computing UI visionary Douglas Engelbart, passes away at  88

The computing world lost one of its great minds and true pioneers yesterday. Douglas Engelbart passed away at age 88, just over a half-century after he joined the Stanford Research Institute (SRI) — the place where much of his ground-breaking computing research would take place. Among his (and his research team’s) many inventions made at SRI are the mouse, bitmapped screens, hypertext, networked computers and elements of a modern, windowed GUI. Should you be among those unfamiliar with his work, we’ve included a video of his epic and appropriately named “Mother of All Demos” that he gave in 1968 to introduce many of his computational contributions to the world. Tip of the cap, Mr. Engelbart. You will be missed, but assuredly not forgotten.

KDE 4.10 released with leaner Air theme, more love for mobile devices

KDE 4.10 released with leaner Air theme, more love for mobile devices

There are plenty of Linux desktop environments to choose from, but if KDE has a special place in your heartware, you’ll be pleased to know its first 2013 update is out. Making the jump from 4.9 to 4.10 brings various tweaks to Plasma Workspaces, including upped support for high-res displays, a streamlining of the default Air theme, and plenty of behind the scenes adjustments. All running software can now be controlled through a common menu system, search indexes happen faster, and the new Nepomuk Cleaner will help rid those clogged drives of unnecessary data. In addition, printer management has been improved, and the enhanced Dolphin file manager communicates more freely with mobile devices. A thorough, lovingly crafted changelog is available at the source link below, but if you’re particularly fond of surprises, then head straight for the download. Happy upgrading!

How-to: Picking a Window Manager in Linux

Picking a Window Manager

When using Linux, or just about any open source operating system out there for that matter, there’s a proverbial Santa’s knapsack of graphical user interfaces (GUIs) available. When you boil this topic down on the basic level, you’ve got two choices: Use a fully featured Desktop Environment (DE) with tons of bells and whistles, or alternatively you can use a slimmed-down and streamlined Window Manager (WM). We’re going to get you up to speed on what each of these actually are, some reasons why you’d want to choose a WM over a DE, as well as some of the options you have among the Window Managers out there. Catch us after the break to join the age-old battle of choosing your GUI.

Meet your desktop’s ancestors: AT&T exhumes footage of the Bell Blit (video)

AT&T exhumes footage of the Bell Blit, shows you where your desktop came from

AT&T’s video archives are rich seams of juicy historical tidbits, and today’s offering is a fine example. It’s sharing footage of the Bell Blit, a graphic interface that Bell Labs developed after being inspired by the Xerox Alto. Originally named the Jerq, it was created by Rob Pike and Bart Locanthi to have the same usability as the Alto, but with “the processing power of a 1981 computer.” Watch, as the narrator marvels at being able to use multiple windows at once, playing Asteroids while his debugging software runs in the background on that futuristic green-and-black display. The next time we get annoyed that Crysis isn’t running as fast as you’d like it to, just remember how bad the geeks of yesteryear had it.

Windows 8 Is “A Cognitive Burden”

Image

It’s hard to blame Microsoft for making bold decisions with its upcoming desktop operating system. But the renamed Windows 8-style UI (or Modern UI) instead of Metro might be too great a departure from known and trusted interactions found in the previous versions of Windows.

According to Raluca Budiu, User Experience Specialist with Nielsen Norman Group, who gave an interview to Laptop Magazine, some design decisions are confusing at best and, at worst, a cognitive burden that slows down the user.

Budiu used to do research in human-computer interaction at Xerox PARC, the very same company that invented the Graphical User Interface and gives therefore a valuable opinion on user interfaces and user experience.

Budiu states that the main problem with Windows 8 will be that users will have to deal with two completely different interfaces, that is to say the traditional Windows desktop interface and the tile-based Modern UI. Not only will some interactions be drastically different in Windows 8, but users will have to keep track of which action to use in which environment.

In addition to piling up two different user interfaces, Budiu believes that the app switcher is problematic. It shows each Modern style app in its own tile but all the desktop apps are regrouped in one tile. Users will have to remember the apps that are currently running on the desktop in order to avoid going back and forth between the desktop and the Start screen.

When it comes to finding a common point between these changes, the Start screen seems to incur Budiu’s wrath. It is both a waste of screen space and unintuitive. The Start menu button is gone and switching between the desktop and the Start screen is not evident at first — the button is hidden in a corner and you must hover to make it appear.

Many of the Modern interface paradigms are taken directly from Windows Phone 7. Buttons are not in plain view and most of the screen real estate is dedicated to content. It should have been adapted more thoroughly to the desktop environment.

The risks for Microsoft are clear. Windows users might react badly to UI changes by using the desktop interface as much as they can. Some will put off upgrading their operating systems. By stating that they won’t offer to boot straight to desktop, Microsoft is courageous. The question now is whether they will be able to stay the course and whether the Start menu is effectively gone forever.


Ceton’s Media Center Companion apps for mobiles hit RC status, add new features (video)

Ceton's Media Center Companion apps for mobiles hit release candidate status, add new features

Fans of Windows Media Center will have a new remote control option soon, as Ceton has pushed out some release candidates of its mobile device Companion apps. Beta testers should be seeing some new features including an updated program guide with infinite scrolling, plus universal search through the guide, movies, recorded TV, TV series and channels, as well as series recording management and overall speed improvements. Currently only the Windows Phone and iOS clients are considered at RC level with the Android version not quite there and lacking the guide search feature. Those in the test group can hit the source links to make sure they’ve got the latest versions of the apps and services for their HTPC, while those of us on the outside looking in can get a quick preview from the demo video embedded after the break and pics in the gallery.

KDE 4.9 arrives, wants to show off its stability

Image

While its austere naming structure may not endear itself to alliteration fans, KDE 4.9 has arrived with a raft of improvements designed to impress Linux users. It’s the first release since the formation of the KDE Quality team, tasked with improving the overall slickness of the desktop environment. You’ll find changes to Plasma Workspaces, the application stack, the Dolphin file manager and Okular, which can now save and print PDF files. If you’re eager to upgrade, the source code is available at the source link and is dedicated to Claire Lotion — a KDE contributor who passed away earlier this year.
