UMPCs and Linux: made for each other, and coming soon

Who knew that the biggest desktop Linux show of 2008 would turn out to be the June Computex show in Taipei, Taiwan, where the next generation of Linux desktop hardware was put on display? In fact, Linux was at the heart of no fewer than four different ultra mobile PCs (UMPC).

At the show, Intel introduced the next two members of its Diamondville Atom processor family. The first to arrive was the N270, which is meant for what Intel calls Netbooks and the rest of the world calls UMPC. The other Diamondville processor, the N230, is meant for mobile Internet devices (MID). Both chips are meant for lightweight (under four pounds) portable computers with battery lives of three hours and up.

The N270 powers four soon-to-ship Linux-powered PCs: Asus’s two new Eee PCs, the Eee PC 901 and 1000; MSI’s entry into the field, the N270; and the Acer Aspire One.

The Eee PC 901 comes with an 8.9-inch screen, a gigabyte of RAM, a 20GB solid state disk (SSD), a built-in 1.3-megapixel webcam, built-in Bluetooth connectivity, and 802.11n Wi-Fi. The 1000H comes with a Xandros-based Linux operating system or XP Home. The 1000H offers a 10-inch screen and 2GB of RAM, but is otherwise pretty much the same system as the 901. An 80GB hard drive is also an option. The 1000H is priced at $679, while the 901 goes for about $629. Like previous Asus Linux-powered UMPCs, the new Asus systems run a variant of Xandros Linux.

Finding these systems today is a challenge — I was unable to find any US resellers who had any in stock — but most vendors are promising shipments in one to two weeks.

The MSI Wind N270, a.k.a. NB-Linux, uses the 1.6GHz Intel Atom N270 CPU and 1GB of DDR2 667MHz memory, with an upgrade to 2GB possible. Unlike Asus, MSI is continuing to use conventional hard drives instead of SSDs. The Wind N270’s default storage device is a 80GB hard drive.

For a UMPC, the Wind has a good-sized screen: 10 inches wide with 1024×600 resolution. For networking it supports 802.11b/g Wi-Fi. Like almost all UMPCs these days, the Wind also comes with a 1.3-megapixel webcam. Its operating system is Novell’s SUSE Linux Enterprise Desktop (SLED) 10 SP2.

MSI promised the Wind would go on sell in May. Now the company, citing a lack of parts, is predicting mass availability of the mini-laptops by late July. It may be later still; Amazon.com is advising would-be buyers not to expect shipments for three to five weeks. When they appear, you can expect to pay about $500 for this UMPC.

Curiously, a twin to the MSI Wind N270, the Advent 4211, is already available in the UK. The Advent 4211, however, is sold by UK retailer PC World as a Windows XP Home-only system. Presumably, the Advent would work with SLED, but UK Linux hackers are spending their time on porting Ubuntu 8.04 to the Wind and Advent UMPCs.

The Acer Aspire One runs the little-known Linpus Linux distribution. The Aspire One will come with 512MB or 1GB of RAM, 8GB of SSD, an 8.9-inch, 1024×600 display, 802.11b/g Wi-Fi, and a webcam. Buyers also have the option of an 80GB hard drive. Eventually, but not in the first release, Acer will offer 3G cellular wireless connectivity as an option, and the company is considering making 802.16e mobile WiMAX an option.

Like the other Atom-powered UMPCs, the Aspire One was supposed to have shipped by now, but it hasn’t. Acer assures would-be buyers that it will be out Real Soon Now. Come the day the Aspire One shows up, it’s pricetag will be about $500 with all the goodies.

A host of other vendors, most notably Dell, plan to release Linux-powered UMPCs this summer. Sources close to Dell confirm that its will be releasing two “Dell E” systems that will use Ubuntu 8.04. The first Atom-powered model is aimed at the growing UMPC market with a price point around $300.

The Dell E Slim, however, seems to be targeting the MacBook Air high-end laptop market. Sources say that this luxury UMPC will be just 0.8 inches thick but will include a 12.1-inch display, a choice between the 1.3 or 1.6GHz Atom processors, an 8GB SSD or a 40GB hard drive, 1GB to 2GB of RAM, 802.11g and n Wi-Fi, and mobile WiMAX support.

Officially, Dell has no word on these plans. Come August, about the same time the other Atom-powered Linux UMPCs actually arrive, you can expect to see Dell Ubuntu Linux-powered UMPCs on sale.

Why openSUSE 11 is the Linux for me

Recently, my colleague James Turner reviewed openSUSE 11 and he liked it. It’s hard to tell from some of the notes he got back-shame on you people!–but he really did.

I, on the other hand, love openSUSE 11 and since Warren Woodford, the developer behind MEPIS, has had to put his great Debian-based Linux distribution on the back-burner for now, openSUSE 11 has become The Linux distribution as far as I’m concerned.

Why? Well, for me, openSUSE is easy to install. Yes, you need to decide if you want to use LVM (Logical Volume Manager) for storage, and that is a mysterious question for new users. But, as Turner points out, all you need do is click on the default choice instead and in a few minutes you’re in business.

Preventing DNS Poisoning in Linux

If you don’t think the recent discovery of the DNS cache-poisoning flaw is bad news and needs to be addressed as soon as possible, let me repeat what Paul Mockapetris, DNS’ (Domain Name System) inventor, had to say about this security hole: Patch your DNS servers right now.

CERT can tell you about the technical details of DNS cache-poisoning, here’s what an attack on a DNS server can mean to you according to Dan Kaminsky, a researcher at security services firm IOActive: The vulnerability could allow attackers to redirect Web traffic and e-mails to systems under their control.

In other words, you click on your bookmark for Google and you end up at a site that looks like Google but is loaded down with malware. Or, you go to what looks like your bank site, the URL is the right one for your bank, but when you enter in your account ID you’ve just given it to a rip off artist.

Developing Open-Source Business Policies That Work: Everyone Is Making It Up As They Go Along

We know your company uses open-source applications. We also know many of you already have an open-source policy. Sort of. As CIO.com discovered when researching the adoption of open-source in enterprise IT, a quarter of respondents have a formal policy in place to control how such software is chosen, supported and deployed. Another 18 percent expected to adopt such a policy in the next 12 months. But those who have some kind of policy aren’t necessarily thrilled with it; just 45 percent said their policies are very effective.

“Somewhat effective” policies are like “somewhat effective” security; clearly, there’s more to be learned. CIO.com asked CIOs and other people in the trenches about what’s working—and what’s not working—with their open-source usage policies. We found that most people don’t really have a formalized policy. What they do have, though, are common concerns. Considered carefully, these issues should help you get a handle on how to better manage open-source software in your company. Once that’s out of the way, you’re in a better position to decide what you want in a formal policy that’s right for your own company.

Building Linux Software the easy way: OpenSUSE Build Service

Let’s say you want to write an easy-to-install program for any Linux distribution. That’s a a problem. There is no single, easy way to install software for all versions of Linux OpenSUSE thinks it has an answer: the openSUSE Build Service.

The openSUSE project, the community Linux distribution supported by Novell, announced the release of its openSUSE Build Service 1.0 on July 7th. The first major release of the Build Service provides developers with direct access to the code repositories for the openSUSE Linux distribution.

Access to code is nice, but this is open source, we always have access to code. What’s more interesting is that the build service enables developers to build programs for different hardware platforms without a “compiler farm” of different hardware. It also provides automatic resolving of dependencies to other packages. If a program depends on another package, say a KDE application on a Trolltech Qt library, the KDE application will be rebuilt automatically if its Qt library is changed and rebuilt. That takes a lot of the drudgery out of building Linux applications .

Ubuntu Linux goes retail

The cheapest way to get Ubuntu Linux is to download it, burn it to a CD, and then install it on your PC of choice. The easiest way to get Ubuntu is to buy it pre-loaded on a Dell PC. The U.S. consumer way to get Ubuntu may turn out to be buy it yourself at Best Buy.

Steve George, director of corporate services for Canonical, announced on a blog that Canonical along with ValuSoft, a U.S. retail software distributor, have paired together to get a boxed version of Ubuntu 8.04 into Best Buy retail stores. The retail box contains a “Ubuntu 8.04 CD, a Quick Start Guide and 60 days of support from the ValuSoft team, trained and backed by the Canonical support guys. The support covers installation and getting started using Ubuntu and is priced at $19.99.”

“The aim” wrote George, “is to provide Ubuntu to users who want the software and support conveniently presented in a boxed set. Making it available through Best Buy is an opportunity to reach users who are unaware of Ubuntu or who are bandwidth restricted and don’t want to download Ubuntu themselves.”

If that describes you, and your closest Best Buy is several hundred miles away, you can also order the Ubuntu package from Best Buy.com.

The packaging is designed to make it clear to anyone that Ubuntu enables users to do the PC basics of “Web Browsing”, “Productivity Suite” and “Email” without any additional software. Or, as I’d put it, $19.95 for the operating system and the office suite vs. $279.90 for Windows Vista Home Premium and Microsoft Office Home and Student 2007.

The real value-add for new users is that the 60-day support contract will make it easy for people who’d get the shakes at the very thought of installing an operating system.  It gives the reassurance of having a helping hand no more than a phone call away.

For users who really don’t want to try to do it by themselves, Best Buy’s in-house tech crew, Geek Squad, will install it for you for $129.95. That’s still cheaper than Windows, but at this point, you’ll really be better off just clicking your way over to Dell’s Ubuntu store.

Dell not your speed? There are smaller companies, like LinuxCertified, that will also sell you preinstalled Ubuntu systems. In addition, other OEMs will soon be offering Ubuntu-powered PCs.

Desktop Linux used to be pretty geeky. With moves like this one, and the flood of Liunx-powered cheap UMPC (Ultra Mobile PCs) like the Asus Eee PCs, by year’s end, it’s going to be just as easy to buy a Linux PC at a local retail outlet as it is to buy a Mac today.
