Google Chromebook: The Computer You Can't Screw Up

I’ve had my Samsung Chromebook for a couple of weeks now.  

A lot has been written about the Chromebook concept, so I won’t go into it in detail here, but in a nutshell, a Chromebook is a specialized small form-factor computing device that is designed to act as an Internet terminal which can rapidly connect the user to network-based services.  It provides a software platform for web-based “apps”  which can be as simple as links to web sites, or as complex as browser extensions using the scripting facilities provided by the Chrome web browser.

My editor has an iPad and I admire its mobility and, more importantly, feeling of immediacy.  A touch or two and you are ready to go.  I have a netbook (actually two) and a netbook is certainly mobile, but it’s still a full-blown computer and that is not always an advantage.

While I understand some of the appeal of the iPad (especially as a media consumption device), the one thing that I can’t understand is how people tolerate its miserable web browser.  Slow and incapable of multitasking, the iPad has the bulk of a computer while unable to perform any better than a smartphone.  To my mind, a Chromebook has many of the desirable attributes of iPad (mobility, immediacy, long battery life) without its limitations.

The tech pundits have weighted in on the Chromebook and I have been quite surprised by the number of negative opinions that this product has spawned.  I guess that I shouldn’t have been surprised given how many negative things were said about the iPad at its introduction.

They Are Missing The Point

Let’s look at the main criticisms being leveled at the Chromebook:

1. “They are too limited.”  The problem many people have is that Chromebooks look like laptops but they don’t do  as much.  Yes, they look like laptops, but they are not laptops.  It is better to look at them as iPads with an actual keyboard, a real web browser, and USB ports.  True, you can’t run Photoshop on a Chromebook, but you can’t run it on your phone either.

2. “They don’t have enough local storage.”  While 16 GB may not sound like a lot, I have noticed that on my netbooks (both of which have 16 GB SSD drives), I don’t store anything close to that much data locally.  I’m always transferring it to other larger machines (Hint: Ubuntu One is your friend).  Besides, unlike an iPad, you can attach USB mass storage devices to a Chromebook.  So, if you want to download that massive video collection, just whip out your 3 TB external drive and go for it.

3. “They are useless without an Internet connection.”  As far as I’m concerned, in this day and age all computers are useless without an Internet connection.  Don’t believe me?  Disconnect your network for a while and see how much you can really get done.  Check your email?  No.  Update your Facebook status or send a tweet?  Nope.  Post to your blog?  Nah.  Conduct research?  Go shopping?  Read the news?  Manage a remote server?  Forget it.

4. “They cost too much.”  For the same money you can get a “real” laptop or netbook,  but name a $430 laptop that will boot in 8 seconds and has 8 hours of battery life.  You also have to consider your definition of “cost.”  Sure, you could buy a lovely Windows 7 netbook for about the same price as a Chromebook, but then you would be confronted with what I call the “money pit of maintenance.”  How much time and money will you spend keeping that machine secured and maintained?  For businesses, the cost of support far exceeds that of the machine itself.  Google uses the slogan “Nothing But The Web,” but they should have called the Chromebook “The Computer You Can’t Screw Up.”   I consider this to be the killer feature of Chromebooks.  There is almost nothing to manage.  Imagine what a business spends maintaining its fleet of PCs each with its own copies of programs and local storage.  With Chromebooks (as with any kind of “thin client” computing model) administration becomes centralized and vastly simplified.  Yes, you may be vulnerable to a possible single-point-of-failure scenario, but I think that many businesses would find this to be an acceptable trade-off.  Oh, and did I mention that a Chromebook is at least $100 less expensive than an iPad.

5. “The Cloud is insecure/unreliable.”  I guess you haven’t suffered a hard drive failure lately, or  had your laptop stolen.  I don’t trust the cloud, but I don’t trust hard disks either.  That’s why I keep backups.

The Philosophical Issue

RIchard Stallman, as you may know, has come out strongly against cloud computing, the model that the Chrome OS so vigorously promotes.  He calls it “stupid” and “careless.”  I think that if you are careless and stupid with anything, you will likely get what you deserve, but I don’t see the cloud as intrinsically evil the way Mr. Stallman does.  I would point out that most free and open source software is developed in the cloud.  Likewise, I don’t see Chrome OS as particularly evil, any more than I see the firmware built into a terminal as particularly restrictive to my freedom.

Where freedom is endangered is with the software that the cloud sometimes provides.  Just like many kinds of proprietary software, cloud-based services have the potential for abuse, particularly by locking your data into a particular vendor’s service.  Also, many of the services provided by cloud vendors are closed-source violating the fundamental tenet of software freedom.

However the concept of cloud computing creates an opportunity for free software and personal liberty.  While the Chromebook demonstrates a certain bias towards Google services, it is not bound to them  You are free to use any cloud service of you want, including your own.

Chromebooks Seem Fine To Me

I, for one, am enjoying my Chromebook.  It fills my need for rapid, lightweight web access without having to support another computer in my “fleet.”

In Praise Of Panix

During the editing of my book, one of my reviewers suggested that it would be cool if there could be an on-line shell host that readers could use to play with command line stuff while reading the book.  While this is an interesting idea, it's not really practical for me to do.

If you have ever received an email from me, you know that my email address contains the domain "panix.com."  What is Panix?  Therein lies a tale.

Panix (short for Public Access Network Corp.) is a small, regional ISP located in New York City.  According to Wikipedia, it is also the third oldest ISP in the world.  They do the usual ISP stuff plus something special.  They provide shell accounts.  In fact, one of their slogans is "Your $HOME Away From Home."  Here is a quote from their web site:

Panix has been providing shell accounts and Internet connections since 1989 —nearly twenty years! During that time we've developed a reputation for technical know-how, reliability and customer service unmatched by today's Internet "superstores". If you're looking for access to a professionally-maintained UNIX host, with the latest versions of all your favorite newsreaders, mailers, compilers and internet clients —and if you want your home and email address to be good for the rest of your life, not just until some DotCom.CEO decides that shell services aren't profitable enough to keep running— you want a Panix account.

We are all shell users ourselves, and we are shell snobs. We know a well-maintained UNIX shell is indispensable for serious programmers, web developers and net fiends. Nothing else gives you as much control over your operating environment, nothing else is as flexible. You know that, we know that, and that is why Panix will always make shell access our first service.

I'm not sure when I started using Panix, probably around 1996 and they have been my faithful partner ever since.  Now since I don't live in NYC, I don't use Panix for my Internet connectivity.  I'm a Verizon FiOS customer at present, but you can still use Panix even if they are not your "primary" ISP.

Panix offers an account called a "No-dial: Full Shell, Remote Login Only" which allows you to use SSH to reach your Panix shell account.  From there you can access a huge array of command line programs and tools.  Included with the account is web hosting, email (accessible directly from the shell with a text mail reader, or remotely via POP or IMAP), USENET access, and 500 MB of disk storage.

In addition to the services, there is the Panix community.  Panix maintains their own hierarchy of USENET newsgroups for access within the Panix system.  Here you will find a vibrant collection of Unix people and other colorful characters.  There is also frequent interaction with the system administrators who are very experienced and knowledgeable.  You can learn a lot just hanging around.

The No-dial account costs $10/month or $100/year if you prepay.



So if you want to experience what a large, multi-user Unix system (they run NetBSD) is like, give them a look

Followup On My Dell Inspiron 530N

Had a problem with the monitor that came with my recently purchased Dell 530N with Ubuntu. After a couple of hours, the monitor would get brighter and brighter until it reached maximum brightness and then after a few minutes of that, the lamp in the monitor would go out leaving me with a black screen. I could turn the monitor off for a few minutes (and presumably, let it cool) and it would work for another couple of hours.

I got tired of that (Hey! I'm trying to write a book here!) so I called Dell's Ubuntu support number (1-866-622-1947) and got connected to an overseas call center. The representative had me perform a simple test, reboot the computer and press F2 to get to the setup screen, then just let it sit and see if the monitor would fail again. This test would eliminate the possibility of a video driver issue. Sure enough, after about 30 minutes, it went out again. I called back and talked to another representative who was able to see what had transpired during the first call. She arranged for a replacement to be shipped overnight to me. A refurbished monitor arrived the next afternoon.

I'm pleased with the service. Their support staff was polite and professional, but I didn't have a chance to test their Linux skills.

Maybe next time.

Review: Dell Inspiron 530N With Ubuntu 8.04 LTS


A couple of months ago I purchased a new desktop system for my office, a Dell Inspiron 530N with Ubuntu 8.04 LTS pre-installed by Dell. For those of you unfamiliar with the "N" series, these systems are sold without Microsoft Windows installed. They are available with either Ubuntu Linux pre-installed or with no operating system installed and a copy of FreeDOS (an open source MS-DOS work-alike) installation media in the box.

My previous computer, another Dell N Series (a Dimension 2400 from 2004) still works but since it's Celeron powered, it's a bit slow for my contemporary tastes.

Ordering from the Dell website was very straightforward and I configured my system with the optional Intel Core2 Duo E4600 processor, 2GB RAM, Integrated Intel 3100 Graphics (I'm not a gamer), and a 22 -inch E228WFP wide-screen flat panel monitor. The total system price was $703 including $35 shipping charge.

After it arrived (it only took about three days even with ground shipping), I got it out of the box and set it up. The only interesting thing of note was that no manual for the computer was included in the box. I don't know if this was a shipping mistake or if Dell omits it because the manual is Windows specific. I later went to the Dell support site and downloaded a PDF version.

Physically, the machine is a pretty typical desktop computer. It features an attractive silver and white case with front audio and USB sockets behind a sliding cover and it has a glowing blue power button. When the system powers up, all of its fans turn on (loudly) for about three seconds and then turn off. Besides that, I would rate the system as very quiet. The standard keyboard is on the smallish side, with no excess around the keys themselves and I had concerns at first about using a keyboard that had no wrist rest, but after having used it for a while, I like the small size. It leaves plenty of room on my desk for even more junk.

The Ubuntu installation on the system is pretty good. Dell adds two icons to the desktop, one linked to a folder named "Dell" which contains a single PDF file of technical support contact information, and a second icon that links to a program that generates a DVD recovery image for performing a full system restore to original factory condition. A recovery partition is also included on the hard disk which can be selected at boot up. What is missing is a document that describes how Dell integrated the OS. Such a document is useful if you later decide to switch to another Linux distribution and need to know if any special tweaks are required to support the hardware.

After the system was attached to the Internet, it set about updating itself from the Ubuntu and Dell repositories. Amazingly, there were over 900 updates available, virtually all of them from Ubuntu. One thing to note about the Dell repositories, packages from there will always display "not authenticated" warnings when you attempt to update them. I looked into this (as the warning you receive is pretty dire) and it seems to be an Ubuntu problem in that only packages from the official Ubuntu repositories can be authenticated.

All of the hardware on the machine appears well-supported by Ubuntu. Dell also includes the closed-source LinDVD program from Corel for DVD (and other multimedia) playback. While the program could be said to work, it has two annoying features, first it always sets the volume level (system-wide) to maximum each time it's started. Second, its user interface is visually ugly, looking like a 1998 version of XMMS. This is the inevitable result of it being closed-source. No one in the GNOME or Ubuntu communities is able to properly integrate it into the desktop. Since receiving the system, I have installed all of the usual multimedia packages from the Ubuntu repositories and reserve LinDVD for DVD watching only and use totem for everything else. The integrated Intel graphics system is fast enough to display 720p video playback without problems. This system is also the first system that I have owned that can run compiz-based visual effects on the desktop and it works pretty well.

Overall, I am very pleased with the system. Dell did a good (though not perfect) job with the Ubuntu setup and the hardware performs well. The 22-inch monitor combined with the compiz visual effects is a delight. For the money, I think this is a very good system. I've enjoyed it every day so far.

Review: Miro


Miro 1.1 from the Participatory Culture Foundation

A couple of months ago I installed version 1.0 of Miro. What is Miro you ask? It's probably best described as a video podcast feed aggregator. With it, you select from over three thousand "channels" (feeds) and it monitors and automatically downloads new programs as they become available. Once downloaded, Miro provides a full screen viewing experience using its own integrated player based on the popular Xine engine. If you have a complete set of codecs installed on your system, you can pretty much watch any web video. The breadth of available programming is remarkable, everything from the wonderfully thoughtful TED Talks to the wonderfully silly Tiki Bar TV. Shows from the major networks are conspicuously absent though there are some entries from PBS, Discovery Channel, Science Channel, and National Geographic.

Miro is an open source project sponsored by the Participatory Culture Foundation. Their goal is to create a truly open platform for Internet television, allowing anyone to publish and view on-line content. This is an important front in the battle for freedom as I, for one, do not look forward to a future where Internet broadcasting is dominated by the handful of media giants that control most content today.

To use Miro, you need a fast computer. As the program is mostly written in python and uses various components from the Firefox web browser, it consumes a lot of CPU cycles particularly during its download process but if you have sufficient hardware, Miro provides a rich addition to your Linux system. Miro is multi-platform (Linux, Windows, MacOS) and is available here.

Review: Linux Administration Handbook


Linux Administration Handbook Second Edition by Evi Nemeth, Garth Snyder and Trent R. Hein

If you, like many readers of LinuxCommand.org, have been tasked with performing system administration on Linux systems, you would do well to get this book. At nearly one thousand pages, this volume covers a wealth of topics vital to anyone using Linux for common IT infrastructure including processes, filesystems, networking, package management, performance monitoring, security, etc., etc.

One aspect of the book I particularly liked was its in-depth treatment of a few specific topics such as TCP/IP, DNS, routing and email. Even users who are not system administrators would find this book useful for gaining an improved understanding of the fundamentals.

While the book focuses on command line administration, it also recognizes the different GUI admin tools available in the popular distributions. The different styles of configuration between various distributions is covered as well, so this book is good if you are confronted with a system that is running a distribution you are not experienced with.

If I were to find one fault in this book (aside from the child-like graphic design which turns off some readers and belies the serious value of the book), it would be that it's uneven in its depth. Some topics have great coverage while others are only lightly touched upon. I'm still looking for a book that covers NFSv4 in any detail for example.

Review: The Official Ubuntu Book


The Official Ubuntu Book by Benjamin Mako Hill and Jono Bacon, Corey Burger, Jonathan Jesse, Ivan Krstic.

I have been working with Ubuntu 6.06 for the last couple of months since its release and have been impressed with its simplicity and elegant design. I think it's a good distribution for anyone starting out with Linux. Likewise, The Official Ubuntu Book is an excellent starter book for new users. It includes a live DVD Ubuntu disk that let's you do a "try before you buy" test of the system before you install it.

The book is well written and includes interesting chapters on the history of Linux and the Ubuntu project. There is good coverage of the installation process for both the desktop and alternate CD versions. The chapter on using the GNOME desktop and its application programs is clear and useful. There is a very helpful chapter containing tips and troubleshooting info along with plenty of links to where to find help from other members of the Ubuntu community. There is also discussion of the server and Kubuntu (KDE centric) variants. For the new Linux user this is great place to start.
