Where to get Technology for Less

We all know that when it comes to prices of technology in Australia, they can often be unreasonable, especially now that the Australian dollar is above parity with the US dollar. So what can you do about these ridiculous prices?

There are several websites which allow you to buy things from overseas at a much lower price than you can get them for here, even after shipping is accounted for. Here is a list of some of my favourite websites to buy anything to do with technology. Just be aware that anything you buy worth more than AU$1000 is subject to a 10% GST charge so some more expensive items such as TVs might not become worth it after accounting for this. There are also some local websites which sell grey import products at very reasonable prices. Some of these may be sourced from overseas and you could be liable to pay tax. For example, JB Hi-Fi has launched their direct import website with grey market SLRs and Lenses however they do mention that the product is shipped from overseas and you are liable for paying GST on purchases over $1000.

Windows Developer Preview Apps

Stocks Windows Developer Build

Stocks

A new stocks app. Looks pretty nice with good graphs. No ASX stocks available yet though

Windows Developer Build Windows Explorer

Windows Developer Build Windows Explorer

The new windows explorer is only available in the desktop mode. It does have the ribbon interface which isn't too bad but it should be better integrated

Windows Developer Build App Store

Windows Developer Build App Store

The marketplace is full of apps as you can see!

Windows Developer Build Connect 5

Connect 5 game

A kind of boring connect 5 game

Windows Developer Build Paint

Windows Developer Build Paint

I'm not actually sure whether this is the official pain app but it looks pretty good

Windows Developer Build Podcasts

Windows Developer Build Podcasts

A new podcast app integrated into the OS. The interface is good with podcasts able to be sorted into groups. It is similar to Windows Media Centre

Internet Explorer 10

Internet Explorer 10

A new version of Internet explorer. It opens websites full screen with the address bar at the bottom and tabs at the top. These pop up when you hover near them. Not so sure about the address bar at the bottom though. It seems a bit strange and unintuitive

Measure app

Measure

Kind of like the measuring app on iOS where you take a photo, set a scale and can semi-accurately measure objects as king as you have no need for depth measurements

Windows Developer Build search menu

Search menu

A nice layout for the new search menu

Piano app splashscreen

Here is an example of the app full screen splash screens

Piano app

A nice piano app for touch screens, not so for mice and keyboards

RSS reader

An RSS reader with a similar layout to the podcast app

RSS reader gesture

If you look on the left side of the screen you can see a pop up of another app. You can just drag another open app from the left side of the screen and bring it up as full screen. Supposedly there's a way of making them split a screen but I haven't figured it out yet

Here is a quick overview of some of the apps included in the developer build of Windows. Most have pretty good concepts but need a bit more work to make them useful. Overall, it gives you an idea of how the OS works and the power of the system.

More pictures will come soon as I discover new features

Review: Telstra Post-paid Mobile Broadband

 

Most people when they hear the name Telstra, they run. Not only have Telstra got a bad reputation from past customers but their plans are notorious for being over-expensive and not even remotely competitive with other mobile carriers. Up until now I believed the same thing, that was until I tried Telstra's mobile broadband offering.

First, the plan i chose was the 7GB Liberty which I got for $39.95 a month (a $20 discount because of having other services with Telstra). Seeing as the normal price is $59.95, this plan is incredibly expensive compared to what you're getting. The $39.95 price makes it slightly more reasonable. Other carriers like 3/Vodafone and Optus give you between 8 and 12GB for $39.95 a month. The biggest problem with all these carriers is their data services are unreliable and not upto scratch. Using a mobile phone as a modem with 3, I got a maximum speed of around 1mbps but it was usually around 400kpbs. This barely qualifies as broadband and it is painfully slow. So despite the extra data you get, it really isn't worth the trouble. Another issue is the coverage. Both Vodafone and Optus are notorious for having poor signal in amny areas and lots of blackspots, most likely due to their overloaded networks. 3 has decent coverage in metropolitan areas but you get hit with roaming charges if you wander out of their coverage area which is anywhere outside major cities and towns.

With Telstra, they give you a free "Ultimate" wireless modem depending on the plan you get. This modem gives you a theoretical maximum speed of 21mbps. In the real world, this is practically impossible but in practice, my internet speed is at 13mbps and has gone as high as 15mbps. Although you have to be living fairly close to the CBD to get these speeds, outside these areas you will still get upto 8mpbs theoretically. The main difference is that these speeds are much faster than any other networks and you can have internet access almost anywhere in Australia with fairly decent signal and speed. So, is it worth the extra cost? Personally, I think it is since with the other carriers you will end up being frustrated trying to get decent signal and the high data allowance will be useless. The other advantage is that with Telstra there are no excess usage charges as with other carriers, once you reach your monthly allowance it is shaped to 64kpbs.

Review: Google Chrome 9

Google

Pros

  • Support for HTML5 and WebGL
  • Super fast
  • Chrome Web App Store is fun
  • Minimalist design
  • Instant works on both search and web pages

Cons

  • Sometimes pages fail to load properly or at all

Review

The latest version of Google Chrome has been released. Although Google releases a new version every couple of months, the browser is constantly evolving and getting faster with each release. I have used all of the main browsers in their latest iterations and although they all claim to be fast, Chrome is by far the fastest. Start up is almost instantaneous and you can basically get straight into your web browsing. With the new Google Instant feature web browsing is even faster and easier than before. All of your web pages and searches start loading as you type which is really good because you can quickly see if there ahve been any updates on the pages and searches become much more efficient.

Speedtest.net a bit inaccurate?

Recently I was having a little problem with my network card. After evetually fixing the problem I decided to do a speedtest on speedtest.net because thats what everyone uses. I ended up getting some interesting results.
My internet connection is supposed to run at 2Mbps (pretty slow i know). Here is what I got from speedtest.net after three different speedtests:

Data Transfer Record Broken!

The famous lab breaks speed records at 100 petabits per second per kilometre over transoceanic distance.

Scientists at Bell Labs have broken records with a new data transfer technique that allows up to ten times the data transmission rates over long distances.

The system has achieved speeds of 100 petabits per second per kilometre over a similar distance to that between Paris and Chicago. The technology will be used to lay much faster international data cables and speed up the global network infrastructure.

“There is no question that this record breaking transmission is a milestone in achieving the network capacity and speeds and a key step forward in satisfying the ongoing explosion in demand,” said Gee Rittenhouse, head of Bell Labs Research.

“This is a prime example of Bell Labs preeminent research and demonstrates the ability of our researchers to solve complex problems.”

The technique uses standard Wavelength Division Multiplexing (WDM) technology but adds 155 lasers, each operating at a different frequency and carrying 100 Gigabits of data per second each.

Repeaters, spaced around 90km apart (around 20 per cent further than are currently used), are used to boost the signal and maintain clarity.

Bell Labs also designed receivers which can disentangle the data from the eventual signal contained in the light.
