"Maybe I'm just naive, but designing a graphics API such that all image data had to be sent over a socket to another process every time the image needed to be drawn seems like complete idiocy. Unfortunately, that is precisely what the X Window System forces a program to do, and exactly what Cairo does when drawing images in Linux - a full copy of the image data, send to another process, no less, every time it is drawn. One would think there would be some room for improvement. Unsurprisingly, others felt the same way about X, and decided to write an extension, Xlib Shm or XShm for short, that allows images to placed in a shared memory segment from which the X server reads which allows the program to avoid the memory copy. GTK already makes use of the XShm extension, and it seems like a good idea to see if Gecko couldn't do the same."

You are comparing apples to oranges. Even more of my users run from remote offices using NX (which is still really X). And believe me... NX blows RDP out of the water for both speed and quality over WAN connections. They are not even in the same class. Proxying RDP (or VNC) through an NX server helps some, but not that much. The OSX approach is nothing but VNC, which is noticeably poorer in quality and speed than even RDP.
X has Xshm which is optimum for local clients, straight X which is optimum for LAN environments, and NX which is optimum for WANs. No other windowing system can touch that combination for performance and flexibility.
Edit: I should mention that as amazing as FreeNX is... it has the rudest and most unhelpful support mailing list in all of Open Source, to the point that if I had another option that was even remotely as good I would migrate to it.

Let's not compare WindowServers of OS X to Xorg. Apple didn't design WindowServer around the notion of a VPN/RDP approach.
I will be interested to see how Apple reimplements NXHost and beyond for 10.6 and the Enteprise.

"Google is facing a new antitrust probe by the U.S. Federal Trade Commission into whether the company is using its leadership in the online display-advertising market to illegally curb competition, people familiar with the matter said." Sucks to be Google today, apparently.

"In the midst of the major press blitz surrounding its annual I/O Conference, Google dropped some unfortunate news about its instant messaging plans. In several places around the web, the company is replacing the existing 'Talk' platform with a new one called 'Hangouts' that sharply diminishes support for the open messaging protocol known as XMPP (or sometimes informally Jabber), and also removes the option to disable the archiving of all chat communications. These changes represent a switch from open protocols to proprietary ones, and a clear step backward for many users." That's why I always say: only suckers trust companies.

"The wave of departures is a sign of internal struggle, but amidst all the bad news, there is a glimmer of hope. According to an anonymous HTC executive cited by WSJ, the crucial HTC One is selling 'pretty good so far'. The executive revealed that HTC sold about five million One units since launch, a performance that is deemed encouraging. However, sales have been limited by the persisting supply issues that still plague the production of the HTC One." Finally some good news for HTC. Five million units amidst supply constraints is very impressive.

"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.

"The Verge has learned that HTC's Chief Product Officer, Kouji Kodera, left the company last week. Kodera was responsible for HTC's overall product strategy, which makes the departure especially notable on the heels of the global launch of the make-or-break One. It's not just Kodera. In the past three-odd months, HTC has lost a number of employees in rapid succession." I really hope HTC pulls it together.

"It is with huge pleasure that the Debian GNU/Hurd team announces the release of Debian GNU/Hurd 2013. This is a snapshot of Debian 'sid' at the time of the Debian 'wheezy' release (May 2013), so it is mostly based on the same sources. It is not an official Debian release, but it is an official Debian GNU/Hurd port release." Important note: 75% of Debian packages are supported bu Debian GNU/Hurd. Impressive.

"The first killer app was VisiCalc. This early spreadsheet turned the Apple II from a hobbyist toy to a business computer. VisiCalc came with room for improvement, though. In addition, a new architecture and operating system, the Intel-based IBM PC and MS-DOS, also needed a spreadsheet to be taken seriously. That spreadsheet, released in early 1983, would be Lotus 1-2-3, and it would change the world. It became the PC's killer app, and the world would never be the same. On May 14, IBM quietly announced the end of the road for 1-2-3, along with Lotus Organizer and the Lotus SmartSuite office suite. Lotus 1-2-3's day is done." Impressive 30 year run.

"There's a disconnect between how Apple CEO Tim Cook sees his company's tax strategies and how some members of the US Senate view it. That became clearer than ever today after Cook and two other Apple executives testified before Congress, explaining why they're holding most of their international income in Irish subsidiaries like Apple Operations International, which declare no tax residency anywhere in the world. AOI hasn't filed a tax return anywhere in the world for the last five years, yet it earned $30 billion in income from 2009 to 2012, according to a Senate report released yesterday." Just because something is legal, doesn't mean it's just. Apple, Google, Microsoft, and many more - these companies might not be breaking any laws, but it's obvious to anyone that what they are doing is scummy.

The new WebKit Opera for Android has been released. "Opera 14 for Android is built on top of Chromium 26, with a total overhaul of the UI in native code, making it fit well with the latest Android design guidelines. Go get the build from Google Play or point your browser to m.opera.com, and give it a spin!"

The Verge pointed me to a blog post by Leap Motion - which reveals how their Kinect-like motion control works with Windows 8. "From the second you plug in your Leap Motion Controller, you'll be able to browse the web and interact with your computer just by moving your hands and fingers in the air. With Leap Motion technology and Windows, you can do everything that's possible with multi-touch inputs - without actually touching anything. This also means that existing applications in Windows 7 and 8 will respond to your natural hand and finger movements. Soon, we'll show you how Leap Motion will work with Mac OS X." Quite cool.More News »
