  • OLPC (One Laptop Per Child) XO Arrived

    OLPC XO beneath an iPod touch and above a Macbook

    My daughter’s OLPC XO finally arrived today (Jan. 3, 2008). In the photo above there is an iPod touch on top of it and an Apple Macbook beneath it to help provide a sense of scale. The first thing I want to make clear is that I think the OLPC is a great idea with startling (in the good sense) design features especially given its low price. So, anything I say that sounds like nit-picking is just that… Little nit-picky notes to help those still waiting for their XO to learn more about the device while they wait. There’s a lot of good reviews and XO focused blogs out there. So, I’ll just mention a few things that I haven’t seen noted elsewhere.

    First my decidedly non-techie daughter who is a bit above the target audience’s age range (7th grade) is very excited about the XO. This actually surprised me. I was even more surprised when she showed a lot of interest in the Python-based Pippy component that is designed to help children understand programming concepts. I used to write a lot of code in Python before I discovered Ruby, so this means I may spend some time back working with Python if she remains interested in learning more about Pippy.

    Second, returning to the theme of a non-techie kid’s reaction to the XO… This week is still part of the winter holiday school break. I was at work when the XO arrived. But, my daughter was at home with her mom. If a Windows based PC or Macbook had arrived, she would have waited for me to come home to plug it in and configure it. But, because the XO is designed to be opened and setup by very young children (much younger than my daughter), she popped XO out of its container, put the battery in, plugged it in to charge it, and started playing with it right away. I actually don’t know what the initial setup screen(s) look like since she had put her name on the system before I got home.

    Third, my daughter commented that the Mac seemed easier to use. But, that is because she has used that at school for several years now. However, she also commented that she liked the circular activity ring that builds as you launch applications. That surprised me a little since it is so different from the more familiar GUI conventions she has used with Microsoft Windows and Mac OS X.

    Fourth, the browser is very fussy about SSL certificates. What do I mean by that? Since the OLPC does not have an IMAP4 email client, I pointed the browser to the web interface for the account I created for her email account. Like many web hosting services, the SSL cert does not match what the browser expects to see. Most browsers complain about this as a potential security risk but let you continue on by pressing a button. XO’s browser rejects the invalid SSL cert and stops dead in its tracks. The non-SSL (plain http:// instead of https://) web interface works. But, of course, this means that everything is transmitted in clear text.

    Fifth, although the XO has some kind of Flash player built in, it is apparently based on an older version and rejected by sites like DisneyChannel.com. This is too bad since so many child and tween friendly sites are Flash based.

    Sixth, the XO’s 802.11b/g WiFi radio doesn’t support WPA (it does support the weaker WEP). The bigger problem for me was that it couldn’t see my 802.11g access point even with just WEP turned on for it. It could see my old 802.11b access point though. So, I was able to get it online this evening.

    Seventh, I was able to briefly get to play with it and opened up a shell window to take a look around. The XO seems to have a good set of tools including ssh and scp. I was able to ssh into a Linux test server with no problem. The XO does not support X Windows (too heavy). So, I couldn’t run X applications remotely. But, a secure remote text shell is usually enough for 99% of quick little systems tasks.

    Eighth, I plugged in an old USB optical mouse and it worked fine. No setup. No configuration. It just worked.

    Ninth, there are apparently two different batteries used by the XO: LiFeP and (the more familair) NiMH. The LiFeP based XO’s are slightly lighter than the ones with NiMH batteries (3.2 lbs. vs. 3.48 lbs.). The one we received has a LiFeP battery.

    Finally (for the moment), the OLPC XO has what looks like a rich set of tools both in the sense of the graphical ones it provides for children as well as under-the-hood ones for systems people. As an old UNIX/Linux hack, I’m looking forward to asking for some play time on the XO to look under the hood a bit more. My daughter had a lot of questions about the XO that I can’t answer yet: Can you change the default screen colors? Does a USB flash drive need to be dismounted before physically removing it? Can we plug in a USB printer? Can the word processor read and write Word files? And many other reasonable questions that we need to dig into over the next few days and weeks.

    I think 2008 is going to be the year of the ultraportable. the Asustek EEE PC led the way in late 2007. The OLPC XO followed up. And, the rumored Apple subnotebook may be announced in less than two weeks at Macworld.

  • Zoho Creator Mobile: Simply Amazing

    Zoho Creator Mobile
    I wanted my first 2008 blog entry here to be a positive one. Well, I’ve got a lot of positive things to say about…

    Zoho Creator Mobile

    …which is part of the Zoho suite of web applications that includes a word processor, spreadsheet, presentation tool, note taker (somewhat like OneNote), wiki, and numerous other web based business ready applications. Zoho creator lets you quickly create web-fied database applications. The mobile aspect of this web service was announced back on November 19, 2007. But, thinking it would take forever to configure a test database for testing on a mobile device, I didn’t take a look at it until now. I definitely should have taken a look at it back in November. I probably could have increased my mobile productivity significantly if I had done that.

    Here’s what I did this evening. I already have a Zoho account. So, I logged in on a Windows-based PC and went into the Zoho Creator module. I was surprised to see that there was a simple drag-and-drop box area on the creation phase that said I could drop a number of client-side data objects including a selection from a live Excel spreadsheet. I opened a spreadsheet containing possible topics for my blogs, selected the range of entries in it, and then pasted it into the Zoho Creator web box. The pasted data looked like a textual mess. “This can’t possibly work,” I told myself. However, when I moved on to the next step, Zoho Creator had correctly identified the header information and associated rows and columns. I wanted to add a new field (column) to the data to test the drop-down box selection feature. And, yep, Zoho Creator let me quickly (within seconds) add a field with pre-defined selection options for the drop-down menu. I saved these changes and moved over to a Windows Mobile 6 Smartphone (Standard Edition) and went to the Zoho Creator Mobile site to see what it looked like there. You can see part of the record entry screen in the figure above.

    After filling out a few (but not all) of the fields, I saved what I had and moved back to the desktop. Back on the desktop, I filled out a few more fields and saved the result. Back on the Smartphone, I took another look at the record and saw the updated information.

    I turned on my iPod touch and went to the Zoho Creator Mobile site to verify that it worked with the Safari browser which, of course, it did (the Safari browser is far more capable than the Windows Mobile Internet Explorer browser). This is a huge win for iPhone and iPod touch users since it lets us easily enter and retrieve data that is instantly available on PC or Mac (or Linux box for that matter).
    BTW, Zoho Creator is not a one-way data ticket. It can also export its data in variety of ways. I chose to export the data back to an Excel spreadsheet including the newly added column (field). This process worked fine. I’m really impressed by Zoho Creator Mobile and will probably use it quite a bit in the near future. The entire Zoho Office suite is far ahead of anything Microsoft or Google have to offer in terms of web services. Zoho even one-ups Google by supporting the Google Gears offline feature that Google Docs doesn’t provide yet.

    I posted the MobileViews Weekly Podcast #2 summarizing blog items here for the week ending Dec. 29, 2007.

  • WifiRouter 0.80: Use a Windows Mobile Phone as a WiFi Router?

    Wow, I didn’t mention anything related to Windows Mobile in this blog this week. So, here’s an interesting freeware utility for Windows Mobile to close out this WiMo-less (so far) week.

    WifiRouter 0.80

    Here’s how its author, Jorrit, Jongma, describes it: WMWifiRouter is a tool to use your Windows Mobile 6 (possibly 5) as a WiFi < -> GPRS/UMTS/HSPA router. It’ll allow you to use WiFi capable devices to connect to the internet through your phone’s data connection.

  • Rumored Apple Sub-notebook

    iPod touch, Newton Messagepad 130, and Macbook

    I generally don’t mention rumors in my blogs. But, like many people, I’m anxiously waiting to see what Apple announces at its Macworld conference in a couple of weeks (Jan. 14-18). One persistent rumor this past year is that Apple is going to introduce some kind of subnotebook sized device. A couple of people are even speculating that it is touch screen device closer in size and form factor to the old Apple Newton instead of a conventional notebook. That would put it around the size of the Nokia N700 and N800 series devices. If this is true, I sure hope Apple learns the lesson Nokia leanred with the release of the N810 and provide a physical keyboard. I still am not comfortable and fast on the iPod touch’s screen keyboard. And, while there are people who have become proficient with it, I suspect many more are in my situation (slow with lots of errors).

  • New U.S. Fed Spare Battery Travel Rules Starting January 1, 2008

    APC Mobile Power Pack

    The U.S. Department of Transportation has new rules regarding to traveling with spare Lithium-Ion batteries that go into effect on Jan. 1, 2008. Check out the…

    SafeTravel.dot.gov

    …site for the details.

    I wonder how much variability there will be among TSA screeners looking at items like spare notebook computer batteries, spare digital camera batteries, and my power workhorse the APC Mobile Power Pack (see photo above)?
