Are our phones becoming too much like computers?

Last week while I was merrily tapping away at my keyboard at work I noticed that my phone (a Nokia N900) felt warm in my pocket. This happens every now and then, I leave an app on and it ends up doing something heavy or a webpage with flash is open. No biggie, I'll just turn stuff off and continue working. The problem was that I had no apps running. Since the N900 runs a full Linux installation, daemons and background apps can sometimes run amok. Being a command-line Linux-guy I looked deeper into my computer-slash-phone and found out that a computer with a Mexican IP-address was running a dictionary attack on SSH (over 3G), trying to break into my phone.

Now, I should point out that first of all I was running an up to date OpenSSH-version (which isn't installed or actived by default for those worrying) and I had a strong password, so I wasn't running a risk of being compromised. But my battery-life wasn't improving either. I shut down OpenSSH* and the next time I need it I'll bind it to WLAN-only, but the question remains:

Are our phones becoming too much like computers?

I, for one, like carrying a full Linux-system in my pocket, but it might require a little too much expertise for most people. The complexity is hidden away in most smartphone OSes, but that doesn't mean it isn't lurking there, in the background. Waiting to be exploited by hackers, virus-writers and other assorted nefarious characters. Be safe and think about what you install on your phone!

*) Turning off SSH in Maemo is a bit tricky - Maemo uses "upstart" for daemons but still keeps the old rc.d-system also, which can be a little bewildering (it was to me). What you need to do is go into "/etc/event.d/sshd" with a text-editor and comment the first line (with #). Then you write "initctl stop sshd" and sshd will be stopped and not restarted automatically.

This Mac devotee is moving to Linux - Dan Gillmor - Salon.com

Apple is pushing computer users as fast as it can toward a centrally controlled computing ecosystem where it makes all the decisions about what native applications may be used on the devices it sells -- and takes a cut of every dollar that is spent inside that ecosystem. This is a direct repudiation of its own history, and more broadly that of the larger personal-computing ecosystem, where no one can stop anyone else from writing and distributing software that other people might want to use.

Steve Jobs says Apple is a curator, nothing more. This grossly understates the control. Jobs says Apple has "made mistakes" in being the police, judge, jury and executioner in its Disney-style world, and is working hard to perfect the system.

But this is a disconnect with reality. Central control, no matter how well-intentioned, is itself the problem, not the solution. The "enlightened dictator" is fiction. And dangerous.

I realize that I won't persuade the many people who prefer to live in gated communities, believing they can leave any time they wish. But switching costs will only get higher over time for those who choose to live in the Apple ecosystem.

Dan Gillmor is saying what I have been thinking for a while, and why I bought the HP Mini 210 netbook. It's so that I can reacquaint myself with Linux on the Desktop and see if it could be an alternative (again).

HP Mini 210, first impressions

I bought my first iBook G3 because I wanted a laptop but the PC-based alternatives of the time were either extremely ugly and bad or very expensive. I stayed with Macs for years because the trend with desktop-replacements on the PC-side was not what I was looking for. Laptops are supposed to be carried around, used everywhere and they shouldn't cost a fortune because they are, in the end, quite fragile and disposable. Now there is finally a class of computers that fit my kind of use, the netbooks.

Yes, I am quite aware that they aren't new things anymore, netbooks were after all introduced in late 2007 (according to Wikipedia) but for a number of reasons it took a while before I purchased my own.

I ended up buying a HP Mini 210, its a 1.22kg laptop with a 10" 1024x600 screen, 1GB of RAM and a hyper-threaded 1.66GHz N450 Atom processor from Intel. At a little over 300 euros that's quite a nice bit of kit for a small price and quite average both in specs and prices of current netbooks.

The computer comes in a simple and small box with little more than the computer, the charger and manuals in several languages. The computer has protective plastic taped over the shinier parts and you have to attach the battery yourself but, while not as elegant as "unboxing" a new Mac, there's really not much you can complain about.

Any complaints should go to the way the OS-installation is handled on new Windows PC:s, the OS is installed when you first turn on the machine which means that you spend the first hour with your new machine watching progress bars. An annoying ritual for anyone who has had the pleasure to start a new Mac - by the time Windows is installed a Mac-user has already migrated all of his or her files and started working.

I went through with the install, not because I wanted to use Windows, but because I wanted to see that the hardware worked and get a feel for how new Windows-computers are these days. The massive amounts of trialware are apparently gone, only Norton and a few other bits and pieces remains but the experience is less than stellar nonetheless. The next day I installed Ubuntu 10.04 Netbook remix - I'll go in to more details about that in a separate post.

The hardware itself is nice, the build quality feels better than many more expensive (larger) laptops but obviously its not competing with 1000+ euro MacBook's. I like the finish of the covers, it's not the glossy fingerprint-magnet that many PC's are nowadays, instead it has a slightly brushed look and feel. Obviously its small and light but still manages to have more USB-ports (3) than many of the MacBooks. The screen is bright and sharp enough to read very well but is glossy which I don't particularly like but its no worse than other glossy screens I guess. The keyboard I particularly like, its very much like any Mac-keyboard with spaces between the flat keys, big and similar enough that I could immediately start to touch-type with decent speed and accuracy. Unfortunately the trackpad is not as good, its small (which is understandable) but has buttons built into the trackpad which makes it somewhat inaccurate, especially if you want to click-hold and scroll. Will take some getting used to and I suspect I might be looking for a way to disable it while typing longer texts.

What else? The battery-life seems decent, its hard to find clear information on how long the battery is supposed to keep up to begin with and using Linux with its less optimized energy-saving will probably drain it faster than in Windows. That said, this morning, while I downloaded and tested out, installed, configured and played around with Linux I had it on for over four hours and had 20% battery left before going into town to eat. If less strenuous use gave me 5-6 hours of productive time I'd be happy - there are Netbooks with bigger and better batteries out there if that's your thing.

All in all I'm quite happy with my purchase at the moment, I will be using it much like a toy to re-discover and play with Linux after a long hiatus from using Linux on the desktop (or in the lap in this case) and as a secondary computer - I'm still keeping my 24" iMac so I'm not abandoning Steve and his funky bunch totally but looking forward to some fresh perspective! I'll write more about Ubuntu Netbook Remix soon.
