School gives every child an iPad

Posted on 01:59 by Unknown
There is a school in the US that is giving every child an iPad according to a news report at CNN. It is spending hundreds of thousands of dollars on the Apple gadget and opinions on the wisdom of this is divided. Is it a good idea for a schools to spend this amount of money on a gadget like the iPad, or should it be spent on books and other traditional educational materials? Of course, there are some great educational apps on the iPad, but you have to bear in mind that the money spent on iPads is not available for other things, such as books. Increasing the spend on technology means decreasing the spend on other things the school might need.

The iPad is costing $475 per child and this would buy quite a few good educational books. It is hard to get children to look after books, never mind an iPad, so you can expect several breakages each year. There will also be a small number of hardware failures because, like all electrical goods, they occasionally fail. They also have a limited lifetime and will need replacing in a few years too. This is a never-ending drain on a school's budget and replacements and repairs need to be factored in to the equation.

Of course, books can be damaged and eventually need replacing, but they are quite likely to outlast an iPad. Maintenance and replacement will be lower with books.

In a perfect world where money doesn't exist or is unlimited then buying every child an iPad would be a great idea, but schools are struggling with limited budgets. The cost of each iPad is not $475 because this is $475 that is not available for other things. I don't know how much money is allocated for the educational needs of each child, but even so, would you want the school to take $475 out of it for your child to buy them an iPad?

Schools have to spend wisely and get the most educational value out of their limited funds and you have to wonder whether this is a good idea.

Secure ways to chat in public

Posted on 02:31 by Unknown
Security is always an important topic with the web and you should constantly be on the lookout for ways in which to keep yourself and your personal information private. One of the ways in which you can improve security on the web is by using an encrypted communication protocol like https instead of plain old http. You'll see it if you ever buy anything on a website or access a bank.

Now you can use https://www.facebook.com and https://www.twitter.com to ensure you have a secure and private communication between your PC and the site. I can see the point when accessing a bank or online store, but why encrypt a conversation that will be made public anyway? Everyone can see what you post on Facebook and Twitter, so why would you want to encrypt its transmission between your PC and the server, only then for it to be made public? Am I missing something here?

When you log in then maybe the password you enter is sent as plain text, but someone would have to be sniffing the network and capture the data for the nano-second it takes for the password to be sent. That would represent a slight security risk, so is this what it's for? It's certainly not needed after login.

Anyway, if you want a secure connection then use the http URLs above. You can also make this a permanent default setting to be used all the time. In Twitter click your name in the top right corner and select Settings. Down at the bottom of the Account tab is Always use https. Tick the box. In Facebook click Account, Account Security. On the Settings tab expand the Account Security section and tick Secure Browsing (https).

Amazon Cloud Drive

Posted on 01:33 by Unknown
Amazon has just launched an online storage service called Amazon Cloud Drive. It can be accessed through a web browser and from any computer, any operating system and by mobile devices too. OK, so that's not unusual, but it is free and you get 5Gb of online storage space for all your files. What's more, if you buy an MP3 music album from Amazon your free storage space gets bumped up to 20Gb, and you can  store your music online too. Just imagine, you can buy MP3 music and store it in the cloud where it can be accessed by any internet-connected device you own!

To claim your 5Gb of free online storage and start uploading files you just need to go to Amazon Cloud Drive and sign in with your Amazon store login name and password. If you've never ever bought anything from Amazon (is there anyone that hasn't?) you can sign up. If 5 or 20Gb isn't enough for you, it is possible to purchase larger amounts of storage ranging from 50Gb ($50/year) to 1Tb ($1000/year).



If you buy a music album from Amazon in MP3 form there is an option to have it placed in your online storage. You can then download it or play it whenever you like. In fact, Amazon has a Cloud Player which works in any web browser and there is an Android app too. Using Amazon Cloud Player you can play your music purchases from anywhere by streaming them over the internet. When you log into your Amazon account you'll see a link to the Cloud Player at the top of the page.



This raises questions of legality and it is a gray area that isn't very clear. Are you allowed to do this or not? More to the point, will the music companies allow it?

Download problems with the Mac App Store

Posted on 12:18 by Unknown
The Apple Mac App Store must work in a strange way because it is causing problems for some people, me included. Some people have found that they can't download any apps. They can get on to the store and click the button to get the app, but then nothing downloads, or it starts and then stops. Some people downloaded apps, but then couldn't update them when they were notified of updates. Here are some solutions for people having problems with the Mac App Store.

There is an article on the Cnet website that might be useful called Mac App Store downloads hanging related to Boot Camp. Apparently if you have Boot Camp set up on your Mac then the App Store might not work properly.

There is also an article in Apple's support database called Mac App Store: Unresponsive after clicking Updates icon. There is some advice that's worth trying.

Searching the web turned up someone who found that changing the MTU network packet size in his router to 1500 solved the problem.

I struggled for a while and then hit upon a different solution. I have an SMC router with an ADSL modem and an Apple AirPort Extreme router for the Wi-Fi:

Mac --- Wi-Fi---> AirPort Extreme --- LAN cable ---> router/ADSL modem

I couldn't download anything from the Mac App Store, even though I could browse the web with Safari, Chrome and so on. I I took the LAN cable and plugged it directly into the Mac instead of using Wi-Fi, cutting out the Wi-Fi and AirPort Extreme. The App Store worked great and downloads were really fast.


Mac --- LAN cable ---> router/ADSL modem


It seems that something in the Mac's Wi-Fi or AirPort Extreme was blocking downloads from the App Store. Whether this solves your own problem is anyone's guess, but it is worth trying.

Cheap software in the Mac App Store

Posted on 02:33 by Unknown
The latest Distimo report is out and it has some interesting facts and figures about Apple's Mac App Store. For example, the average selling price of the top 300 apps is $11.21, or as we say over here £6.91. That is a very low price and perhaps it has something to do with the success of the App Store. It's obviously easier to shift a lot of cheap software than expensive items and people are always on the lookout for a bargain.

This is great news for consumers and it would be fantastic if the App Store continued to supply low cost software, but is it such good news for developers? It's a bit of a gamble pricing a product very low in the hope that a sales high volume will compensate this.

You often see headlines and stories about the massive number of downloads that products get and the huge revenue that some companies earn, but the really interesting statistics are never revealed. I wonder whether a small number of people are making a lot of money and the vast majority are making very little. It's just a suspicion on mine.

There are 300,000 apps in the iOS app store (iPhone, iPad, iPod Touch), but how many can you find? Start iTunes and browse the store and you'll find a few hundred, perhaps a thousand a most, and these are apps of the week, top free/paid lists, highlighted ones and so on. There must be tens of thousands, maybe hundreds of thousands that Apple never highlights on the few pages it dedicates to apps in the store and I'd like to know how many sales they get.

Conflicting iPad buyer surveys

Posted on 02:37 by Unknown
Just sitting at McDonald's reading through the latest headlines on my RSS feeds and I noticed a couple that immediately stood out. Both are articles at Apple Insider. The first one is titled Survey says 70% of first iPad 2 buyers own original iPad, but the second one says Apple attracts 70% of new buyers with iPad 2 launch - survey. So one says 70% of buyers already own the original iPad and the other says 70% don't. Which is right? They both are and it just shows that you can always find statistics to support any point of view you like.

They were both surveys that looked at the people queuing up to buy the newly launched iPad 2. There were big queues at some Apple stores and they ran right around the block - hundreds of people. The two very different survey results show that the makeup of these queues can vary greatly.

The big problem with articles and surveys like these is that some people will read just one and use it to support their argument, theory or point of view. One survey like this on its own is meaningless and to get an accurate picture of iPad 2 buyers you would really need to perform 100 surveys and then combine all the results.

The headlines of these articles aren't wrong, they are right, but they don't actually mean anything.

Samsung rethinks its Galaxy Tab

Posted on 02:30 by Unknown
Anyone can be a blogger (hey, look at me!) and anyone can post their thoughts, ideas and comments online, but how many are worth reading? There's a lot of rubbish posted on the web and it gets depressing and irritating reading it. I subscribe to lots of RSS feeds to keep up with the latest news and the Apple ones are the most irritating. An article titled "Samsung Gets iPad 2 Envy" starts off with the sentence "Samsung Electronics is already rethinking its Galaxy Tab lineup after the unveiling of Apple's second generation iPad." Doesn't everyone rethink everything? We'd still be swinging from trees with the rest of the apes if we never rethought anything we do and looked for better ways of doing things.

Didn't Apple rethink the iPad to come up with the iPad 2? It thought "How can we make this better next time around?" It will rethink the iPad 2 and ask the same question to come up with something even better for the iPad 3. Samsung is rethinking its Galaxy Tab lineup just as Apple is rethinking its iPad, iPod, iPhone, MacBook and iMac lineup. Car manufacturers are rethinking their cars in order to come up with better cars, chefs are rethinking their recipes to come up with even tastier ones, television manufacturers are rethinking their TVs to come up with improvements that will enhance the next generation. Everyone rethinks everything and it's the way technology progresses.

Here's another quote from the article, "We will have to improve the parts that are inadequate, " said Samsung. Once again, this is something everyone does and it's not just Samsung responding to Apple's iPad 2. I'll wager that the iPad 3 will have a better screen, perhaps a retina-type display, or a better camera with a higher resolution. After all, the back camera takes photos that are less than one megapixel! Apple will improve the parts that are inadequate when it designs the iPad 3. Everyone does this. The parts on a device produced last year are inadequate compared to what's available this year or next year, and so on.

The difference between Samsung and Apple is that Samsung is thinking out loud and sharing its thoughts with the whole world. Apple says nothing and keeps quiet. Both companies are rethinking designs and replacing inadequate parts with better ones though.
