Linux Ultra-Portables

Leave a comment

Engadget has a nice feature on the growth of Linux based UMPCs.Linux Ultra-Portables

ASUS set the pace with Xandros on the Eee PC, and HP has tapped Novel SuSE Linux for the 2133 Mini-Note, but whereas the Eee’s positioning has been somewhat of a loose hybrid between an adult OLPC and the Nintendo Wii’s culture of global inclusion, the HP Mini-Note has been strongly focused on reckless, immature students while acknowledging potential for senior executives that have been known to share their temperament.

It’s interesting to see how this product niche has almost appeared from nowhere and is growing rapidly.

It seems to be a product that appeals to people who already own a computer, but want a laptop (and a small laptop at that) to complement it. The advantage of these little Linux laptops as well as the small size is the small price.

I have already seen quite a few of these laptops in college, brought in by learners, so I am expecting to see more of them.

Wireless security

Leave a comment

When it comes to wireless security there are lots of myths out there.

Wireless security

Ars Technica has published a nice article on wireless security which covers many of the key issues and importantly debunks some of the myths out there as well.

The SSID (Service Set Identifier) is an identification code (typically a simple name) broadcast by a wireless router. If a wireless device detects multiple SSIDs from multiple access points (APs), it will typically ask the end-user which one it should connect to. Telling a router not to broadcast its SSID may prevent basic wireless access software from displaying the network in question as a connection option, but it does nothing to actually secure the network. Any time a user connects to a router, the SSID is broadcast in plaintext, regardless of whether or not encryption is enabled. SSID information can also be picked up by anyone listening to the network in passive mode.

Lots of dongles

4 Comments

BBC reports on how the use of 3G for data is increasing really fast.

This graph from 3 shows how fast 3G data usage is rising.

Lots of dongles

Why is this, well according to Rory Cellan-Jones of the BBC, the reason is simple.

So what’s behind the sudden explosion of data use? One word: dongles, those plug-and-play devices that give your laptop mobile broadband wherever you go.

3, T-Mobile and Vodafone have been pushing their 3G USB dongles hard over the last few months, and the monthly cost of such services has dropped considerably.

When I first used 3G in June 2004, I was paying £100 per month, now you can get 3G for just £10 per month, and as part of a phone plan it can be as little as £5 per month!

Also we are seeing an explosion in speed (just don’t tell O2 who are still stuck on 128Kbps), back in 2004, I was lucky to get 384Kbps, today with my Vodafone 3G dongle I can achieve 7.2Mbps (well I can in London, less so in Gloucester).

These fast speeds start to make 3G a viable option for many people.

With more people using 3G dongles and laptops, suddenly they will be able to access media-rich learning content where they like, mobile learning starts to become more real and accessible.

Of course as noted in the BBC, problems start to arise if you exceed the fair use limits of these 3G services.

Photoshop Express

4 Comments

Adobe have released an online photo editing app which they have called Photoshop Express.

You shot it — now do something to it. Make it pop. Make it impossible to ignore. Upload, sort, polish, and store up to 2GB of photos. All for free. Resize, tint, distort, and more — add your mark to all your images. Then show them off on Adobe® Photoshop® Express or your Facebook page.

A bit of a warning, this is not an online version of Photoshop. This is an online photo editing application which Adobe have called Photoshop Express.

It reminds me a lot of iPhoto and many Mac users will find it pretty simple and easy to use and very familiar, but obviously Photoshop Express also works on Windows PCs.

Unlike (the real) Photoshop which has a pretty steep learning curve this has a pretty simple interface which works quite well.

Photoshop Express

Certainly worth a look as both an online photo editor but also as an online photo storage tool.

3D GPS

Leave a comment

Do you have a GPS or satnav and still get lost?

Could it be because the maps on satnavs look like maps rather than the place where you actually are?

Though I think GPS devices have a place in learning and especially mobile learning they do have a requirement that the learners understand maps and the concept of maps and am not sure that all do.

In Korea we are seeing the future of satnav with the map been replaced by a 3D view of the road you are on.

3D GPS

Thinkware announced the launch of its premium navigation device ‘iNAVI K2’ in Korea market, which is equipped with its dynamic electronic map of 3D space representation ‘iNAVI 3D’.

Adopting 8GB SDHC memory card and 256MB of RAM, the iNAVI K2 provides useful information on the 3D environment structure through a 4.8-inch WVGA(800 x 480 resolution) LCD in a photo realistic way.

Of course with initiatives like Google Street View in the US, eventually we may see (in the UK) photo-realistic 3D environments on satnav devices.

This all means for learners that they will find using GPS devices much easier to use for location based learning activities.

Yahoo to adopt “semantic web”

2 Comments

Yahoo is going to adopt some of the key standards of the “semantic web” in order to improve the search experience for its users, reports the BBC.

The technology is widely seen as the next step for the world wide web and it involves a much richer understanding of the masses of data placed online.

Andy Powell Pete Johnston makes some additional observations on his blog entry:

It is worth bearing in mind the note of caution from Paul Miller that such an approach brings with it the challenges of dealing with malicious or mischievous attempts to spam rankings, and as I think Micah Dubinko’s post makes clear, this is not going to be an aggregator of all the RDF data on the Web.

Wikipedia on the semantic web.

Edit: Corrected who wrote the blog entry on eFoundations.

Please do not send 17MB Word attachments…

2 Comments

As per usual when I am out of the office for a while I get the usual “Your mailbox is over its size limit” as I do send and receive a large amount of e-mail (even more so when I am out of the office as it is my main form of communication).

Please do not send 17MB Word attachments…

Now it’s very difficult to archive from a remote location, so I do go through and trim a few e-mails and download and then delete large attachments.

However was very surprised to see literally one day after doing this he “Your mailbox is over its size limit” message again, I checked I hadn’t received any new BIG e-mails for a while, so I thought I know I suspect that an all staff e-mail with a large attachment had been sent round.

And boy was I right!

Somone (who shall remain nameless as this is a public blog) had sent for sending to all staff an e-mail with a single Word document as an attachment.

This Word document was a single page document, with some pictures on it.

This Word document in terms of file size was large, nay huge, nay really really BIG!

It was 17MB, that’s right seventeen MB!

17MB for a single page document!

Obviously the person who had created the document had taken some photographs with a digital camera and inserted them into the word document, resized them so they fit on the page, but not resized them in terms of file size!

17MB for a single page document!

Now with other a thousand staff, that means the mail server was choked with 20GB from a single e-mail!

I suspect I was not the only one who received the “Your mailbox is over its size limit” e-mail this weekend and I suspect that there will be a lot of people who will be very annoyed and will just delete the Word document without opening or downloading it.

Really that file should have never been sent, posted as a link perhaps (but would you download a 17MB Word document).

I did go ahead and print it as a PDF and got it down to 300KB without trying which is still large, but so much better than 17MB.

Maybe next time a simple text e-mail would have sufficed.

Learning on the Wii

Leave a comment

A MoLeNET colleague of mine has been playing working hard on seeing how the Nintendo Wii can be used to support learners.

Learning on the Wii

http://www.xlearn.co.uk/2008/03/learning-on-wii.html

http://www.xlearn.co.uk/2008/03/getting-your-wii-on-net.html

I’ve finally got round to buying some points and downloading Opera on my Wii. I’m excited by quite a few possibilities in its use for education, especially since some colleges I know have bought them to support learners in their Entry Level courses for the Learning for Living and Work projects.

From my perspective this device can be used for mobile learning in addition to learning in college.

For some learners this is their “mobile” device.

If learning while mobile means learning at home using a console, that has to be an advantage over “not” learning at home.

If I am at home learning on the net on my wifi capable Nokia N95 is that more or less mobile than learning on the net on my 17″ MacBook Pro on Brighton beach using the free Pier to Pier wireless network?

Do you have to be at Starbucks using their wifi for it to be mobile learning?

Surely it is all about choice, and learner choice at that?

The latest street danger? Walking and texting

Leave a comment

From the Guardian…

In case anyone reading this is one of the 68,000 individuals who apparently interfaced thus with street furniture in London last year (mostly resulting in cuts and bruises, but with a fair proportion of broken noses, cheekbones and one fractured skull in the mix too) and therefore is self-evidently stupid enough to need the problem further delineated, these are injuries caused by people who do not understand the importance of peripheral vision. Until, that is, they compromise it by texting as they walk along the street and into lampposts, signs, bollards and other pedestrians.
