Tethering on a Budget with Opera Turbo

I have a bargain basement data package on my mobile phone that includes a mere 250Mb per month of data. I am sure that my provider would love me to upgrade and the threat of completely outrageous out of package rates does weigh on my mind (would you believe 2c per kb!!!) but 250Mb is really more than adequate for all my small screen Internet needs. A typical half hour browsing blogs and forums during my morning commute to work uses no more than a megabyte or so. While a quarter of a Gb might seem piteous to an Iphone using you-tube junkie it more than suffices for my text heavy web browsing tastes.

At least it did until I discovered tethering. You see my new laptop has built in Blue-tooth and my phone is happy to share the benefits of browsing anywhere to the laptop through the magic of tethering. Except there is a problem. My first 10 minute browsing session via tethering consumed 10Mb of data. A quick back of envelope calculation indicated that I could blow my entire monthly data allowance before the laptop battery ran out. Not good.

I was actually surprised that laptop browsing was so data intensive compared to the phone. Admittedly I was using the freedom of tabbed browsing to consume multiple pages at a time and I was also more inclined to follow through on media rich content links. One less obvious reason though is that I use Opera Mini on my phone and the nice people at Opera offer server side data compression. This means that Opera's servers actually compress the data you are viewing before sending it to your phone which greatly reduces the bandwidth required. There are trade-offs particularly in terms of image quality but for the most part it works.

I wanted to see if something similar (and in particularly something similarly free) was available for a Windows browser and happily it turns out that Opera 10 has a built in "Turbo" mode that does just that. Using it on the Laptop I am getting average compression of about 3 to 1 which will definitely help stretch my meagre data allowance. The degradation in image quality is more noticeable on a laptop screen than on a phone but pages are still very readable. Flash games don't seem to work at all in turbo mode but youtube videos work once you confirm that you want to download them. I suspect that compression is turned off for the duration of the video though. An added bonus is that the compression helps squeeze a bit more speed out of the slow 1Mb/s blue-tooth link to the phone.

Of course if you are concerned about privacy you might not like the idea of Opera getting a peek at everything you do on the web as it goes through their servers but I think it is a worthwhile trade-off.

This iPhone user is govened by text browsing like google reader too but also Twitter app and facebook. YouTube is not something I'd stream on my phone

Hi DM. I Googled around a bit and was surprised to see that the average Iphone user hardly uses more than the 250Mb allowance I have.

How do the carriers get away with selling multi-gigabyte data packages so when the vast majority of their customers just don't need them!

My First Gaming Mouse: Logitech G300

I bought a gaming mouse yesterday a Logitech G300, here my initial thoughts. What is a gaming mouse?  There are a wide variety of devices available classified as gaming mice but a few features  seem common: 1. Wired rather than wireless: Although some high end models are wireless wired connections are just better and faster than wireless so most gaming mice stick with wired. As a bonus wired mice don't need batteries so the mouse is lighter.  2. High response rate: 1 to 2ms response rate so the mouse immediately responds to input.  2. High DPI. Gaming mice invariable boast high DPI numbers from 2,000 DPI upwards. This makes the device very responsive to the smallest movements.   3. Adjustable DPI . High DPI improves responsiveness but reduces precision so gaming mice generally allow you to adjust the DPI down for precise work such as pulling off headshots in sniper mode. Generally the mouse allows dpi to be changed on the fly by pressing a button.  4. Extr

Android Tip 3: Sharing a Folder between multiple users of an Android device

Android has allowed multiple user logins for quite a while now. This is can be very useful for tablets which are shared by family members. Normally Android erects strict Chinese walls between users preventing them from using each others apps and viewing each others files. This is a useful security feature and ensures your kids don't mess up your work spreadsheets when screwing around on the tablet and should also prevent them from buying €1,000 worth of Clash of Candy coins on your account. Sometimes however you really do want to share stuff with other users and this can prove surprisingly difficult. For example on a recent holiday I realised that I wanted to share a folder full of travel documents with my wife. Here are some ways to achieve this. 1. If you have guaranteed internet access  then you can create a shared folder on either Dropbox or Google drive. Either of these has the great advantage of being able to access the files on any device and the great disadvantage of bein

Portal 2 two screen coop on one PC.

I mentioned before that I intended to try Portal 2 in "unofficial split screen co-op mode. Well split screen on a small computer monitor is a recipe for a headache especially when the game defies gravity as much as portal. However a minor bit of extra fiddling allowed us to drive two seperate screens from one PC. The Steam forums describes a complicated method of doing this that I couldn't get working so this simpler method which worked for me might be of use to someone. 1. First I followed the instructions in this post to get split screen multi-player working: http://forums.steampowered.com/forums/showthread.php?t=1847904 A minor issue not mentioned is that you need to enable the console from the keyboard/mouse options menu I am using keyboard and one wired Xbox360 controller as suggested. Getting the controller to switch to channel 2 was tricky at first but as Chameleon8 mentions plugging it out and in again during loading works. The trick for me was to do the plug / p
