Want to Rent a Movie on Your Apple TV?

Online movie rentals have long been available on both cable and satellite TV systems. There’s always been one little, well not so little, problem. Actually, renting the movie tends to be a pain.

You usually must call up the service, jump through an automated voicemail system, and, in some situations, then wait for the next time the movie starts on its designated channel before you can watch it. Wouldn’t it be better if you could just rent movies online the same way you do at a hotel? Click the remote a few times, pick a movie, hit OK and you’re watching your movie. This is how home movie renting should be, but it’s not.

Until now. It appears that Apple is getting ready to offer exactly that kind of service for the Apple TV or your computer using the latest version of iTunes: iTunes 7.5.

VirtualBox: The best virtualization program you’ve never heard of

Quick, name some virtualization programs that run on Linux.

Time’s up.

If you’re like most people, you probably named VMware or Xen first. Many of you probably know of one or more of the following: Parallels, QEMU, KVM, Virtuozzo and OpenVZ. However, few of you probably know about VirtualBox. And chances are if you know about VirtualBox 1.502, you’re already running it because it manages the trifecta of being good, free and, sort of, open source.

Sort of? Here’s how it works. InnoTek, a software company in Stuttgart, Germany, has released both a proprietary and a GPLv2 open-source version of the program. The VirtualBox OSE (open-source edition) has a subset of the features of the proprietary version.

VirtualBox OSE is not crippleware. It’s as full-powered a virtualization program as you’ll find today. What it’s missing are additional features, not basic functionality. You can also use the proprietary version, without charge for personal and educational use and to evaluate it for possible business purchase.

Rotten Apple: Leopard

Apple’s latest operating system release may be the most troublesome since Apple switched from its System operating system to the BSD Unix and Mach-based Mac OS X.

I have never heard so many complaints about a Mac OS upgrade. Back in 2000/2001 when Apple users were switching from its older System operating system to the BSD Unix-based Mac OS X, I also heard many a die-hard Mac user cursing at the changes. Then, however, everyone knew that there was going to be real trouble. After all, this wasn’t just an upgrade—both the software and hardware were moving from one operating system to another.

Leopard’s (Mac OS X 10.5’s) problems have shocked the Mac user community. Most Mac users would have agreed with me that Leopard wasn’t supposed to be a major step forward. Instead, it was going to be many small steps forward for the Mac. Well, that was the idea. It’s turned out to be a major step backward.

Linux-powered Asus Eee PC mini-laptop arrives

The Xandros Linux-powered “ultra-mobile PC” (UMPC) has finally arrived. One of the most eagerly awaited laptops in some time, the tiny Asus Eee PC 4G, is now available from online retailers that include Newegg and Directon.

When the news first broke that Taiwanese computer manufacturer Asus was coming out with a less than two pounds mini-laptop for under $200 that would be running Linux, both gadget and Linux desktop fans were thrilled. Now that it’s here, the Eee PC 4G’s price has doubled, but early reviewers are still finding this Xandros-Linux powered laptop to be worth the price.

It helps, though, to keep in mind that this is not a full-blown laptop. If that’s what you want, we recommend you check into Dell’s Ubuntu-powered Inspiron 1420 Notebook, or Lenovo’s ThinkPad T Series business notebooks with SLED (SUSE Linux Enterprise Desktop) 10 SP 1.

What’s the difference? Well, for one thing, instead of an 80GB hard drive, the Eee PC 4G has a 4GB SSD (solid state drive). In place of the 1.5GHz Intel Core 2 Duo T5250 processor that the 1420 comes with, the Asus UMPC uses a 900MHz Intel “Dothan” Celeron M CPU.

It’s all a matter of setting expectations. If you want an inexpensive, light-weight system that can handle all the home, work, and Internet basics, the Eee PC 4G may be all you need.

The 7-inch diagonal LCD screen, which is driven by an Intel Graphics Media Accelerator 900 GM chipset, has an 800×480 pixel resolution that’s perfectly adequate for most program use. You may, however, find yourself needing to scroll back and forth horizontally to view some Web sites.

Reviewers agree, to no one’s surprise, that the keyboard is on the small side. It’s about 4/5ths the size of a conventional laptop keyboard. On the other hand, the size reduction has been taken out mostly on the function keys rather than the alphanumeric keys. The result seems to be a keyboard that’s a lot more usable than, say, a Blackberry Pearl’s, but not the equal of a normal notebook’s keyboard.

The scratchpad, in particular, has been singled out as being too small. Fortunately, Asus didn’t scrimp on the ports.

The device provides three USB 2.0 ports. I’d suggest plugging a mouse in immediately.

It also has a 100Mbps Ethernet port, a modem, and built-in WiFi (802.11a/g) for your network needs. There’s also a VGA port for external monitor hookups.

While the machine doesn’t have any kind of optical drive, it does have SD (Secure Digital) and Memory Stick card readers. You can use these for either their typical jobs — importing photographs or video — or what might be even more useful, as secondary storage to the built-in SSD.

The version of Xandros on the Eee PC 4G uses the KDE environment. The desktop has been customized to make it as easy as possible to use. For instance, the initial screen consists of a set of four tabbed pages: Internet, Work, Learn, and Play. On each page you’ll find the appropriate icons for that page’s set of applications.

The system’s applications include such usual Linux favorites as OpenOffice, Firefox, and Thunderbird. To make life easier still, some pages include links to useful sites such as Google Docs.

Even though this is a lightweight laptop in just about any way you’d take the word, “lightweight,” it does have one heavyweight feature. This is that, thanks to Xandros, it works extremely well with Windows networks. From all reports, and our own experiences with Xandros on other PCs, it’s easy to hook the Eee PC 4G to Windows or Samba network drives and printers.

So, is it worth it? From what we can tell, the answer depends mostly on what you want from a laptop. If you’re a power-user, or a Linux maven, this isn’t a system for you. If, you just want a cheap, light mini-laptop to toss in your luggage and be able to do the basics at home, office, or on the road, it might just be the baby laptop you’ve been waiting for.

No worries: head of MEPIS Linux is fine

Users of the popular Linux distribution MEPIS were getting worried about the distribution’s leader, who had been rather quiet lately.

Some Linux distributions — Red Hat, Ubuntu, and Novell, for example — have thousands of people working on them over the course of a month. Others, like MEPIS, have one developer, and users of the popular Linux desktop distribution were getting worried when Warren Woodford, MEPIS’s CEO, had been laying low for the last month.

Usually, Woodford is an amazingly productive Linux developer. His MEPIS distribution is well-regarded and has tens of thousands of users. He keeps in touch with them via the main MEPIS Web site and by the community site, MEPISLovers. Since Woodford released the last beta of MEPIS 7, MEPIS 7.0 Beta5, Woodford had been quiet. Too quiet for the peace of mind for some MEPIS Linux users.

Some of them began to worry that he was in ill health. As one member of the MEPISLovers site wrote to me, “The general tone is that he’s gravely ill and that MEPIS is going the way ‘Libranet’ went.” Libranet was a one-time popular Linux distribution. After the death of its founder, Jon Danzig, in June 2005, the distribution struggled on for a time under his son Tal, but eventually went under.

The truth, however, has nothing of tragedy in MEPIS’s case — and everything of the mundane. Linux-Watch was able to reach Woodford. He said, “I’m fine. MEPIS was slowed down, because I finally had to reenter the workforce as a consultant in order to pay the bills. I can net more in two weeks of consulting, then in a year with MEPIS.”

That doesn’t mean he’s stopped work on MEPIS by any means. “I have Beta 6 in the mirrors and I will issue a press release soon. Next week, I will have a corporate apartment near my client and then I will be able to resume a regular development schedule for MEPIS. I hope to go final very quickly, maybe around Thanksgiving.”

This version of MEPIS is a return to its Debian roots. The last edition, version 6.5, was built around Ubuntu. However, Woodford didn’t care for how packages were being maintained for older versions of Ubuntu, so he decided to go back to Debian and use Debian 4.0 for the basis of his distribution.

The ISOs and deltas for 32- and 64-bit processors are now available from the testing directory at the MEPIS subscriber site and public mirrors. The current pre-release, beta 6, includes updates that include KDE 3.5.8, Linux kernel 2.6.22.10, and Skype 1.4.0.118. Additionally, icaclient 10.6, which enables Linux to work with Citrix’s WinFrame and Presentation Server, had been added to the MEPIS pool. The first release candidate is scheduled to be released around Nov. 10 and a second release candidate around the 17th of the month. The final release is, as Woodford said, tentatively scheduled for Nov. 24.

So, there you have it. Woodford and MEPIS are both fine. It is, however, a bit sad that even an excellent Linux distribution, if it doesn’t have a large company behind it, can’t support its founder.

SFLC, BusyBox and Monsoon agree to dismiss GPL lawsuit

On Oct. 30, the Software Freedom Law Center, acting on behalf of the two principal BusyBox developers, and Monsoon Multimedia jointly announced that an agreement has been reached to dismiss the GPL enforcement lawsuit, which had been filed by the SFLC.

This was the first time in the United States, according to the SFLC, that a company and software vendor, Monsoon, was going to be taken to court for a GPL violation. Previously, alleged GPL violations have all been settled by letters from the FSF (Free Software Foundation) or other open-source organizations, pointing out the violation.

Monsoon makes consumer devices primarily for home multimedia users. One such device was Hava, a place- and time-shifting TV recorder similar to the SlingBox. It was the Hava that got Monsoon in hot water with BusyBox’s developers.

BusyBox is a set of tiny versions of many common Unix/Linux utilities into a single small executable. By providing replacements for most of the utilities ordinary found in GNU fileutils, shellutils, etc., developers get much of the expected functionality of the GNU utilities without the space requirements. Thus, the BusyBox programs are used in many — perhaps most — embedded Linux-based devices, such as Numark’s iDJ2, a Linux-based DJ mixing console built around the Apple iPod; Drew Tech’s DashDAQ car engine computer; and Pinnacle Audio’s Athenaeum music server.

BusyBox is open-source software licensed under the GNU GPLv2 (General Public License version 2). One of the conditions of the GPL is that re-distributors of BusyBox are required to ensure that each downstream recipient is provided access to the source code of the program. Monsoon’s sin was that it had used BusyBox in its Hava line without providing access to the BusyBox code.

Once the matter came to the point that the SFLC filed suit against Monsoon, the company quickly agreed to comply with the GPLv2 requirements. That in and of itself, though, wasn’t sufficient.

Lead SFLC attorney Daniel Ravicher explained that the delay was because “simply coming into compliance now is not sufficient to settle the matter because that would mean anyone can violate the license until caught, because the only punishment would be to come into compliance. I can’t discuss the details of what additional things are being sought by our clients, but hopefully we’ll be able to shed light on that if/when we do reach an agreement.”

Now, that agreement has been reached. As a result of the plaintiffs agreeing to dismiss the lawsuit and reinstate Monsoon Multimedia’s rights to distribute BusyBox under the GPL, Monsoon Multimedia has agreed to appoint an open-source compliance officer within its organization to monitor and ensure GPL compliance, to publish the source code for the version of BusyBox it previously distributed on its Web site, and to undertake substantial efforts to notify previous recipients of BusyBox from Monsoon Multimedia of their rights to the software under the GPL. The settlement also includes an undisclosed amount of financial consideration paid by Monsoon Multimedia to the plaintiffs.

“Although we really hated having to ask our attorneys to file a lawsuit to get Monsoon Multimedia to abide by the GPL, we are extremely pleased that they worked so hard and so fast to come into compliance,” said Rob Landley, a developer of BusyBox and a named plaintiff in the lawsuit, in a statement.

“Going forward, we are confident that Monsoon Multimedia will be upstanding members of the open-source community and we wish them the absolute best of luck with their business,” said Erik Andersen, the other BusyBox developer named as a plaintiff in the lawsuit.

“We are happy to put this behind us and move forward,” said Graham Radstone, chairman and COO at Monsoon, in a statement. “The fact that Monsoon Multimedia and BusyBox have reached an agreement amicably shows that settlement is far better than costly litigation. We will ensure that we are in compliance with the agreement in the future. Monsoon Multimedia is a highly innovative company and occupies a leading position in the emerging place-shifting market; therefore it is essential that we set an example for compliance for others.”
