Can green technology help us get out of the red?

14 Replies Christopher Roberts

Most people know that the world has recently emerged from an economic recession. Many people also know that we are all dangerously close to slipping back in, and are replying on governments around the world to keep us in the black.

However, has anyone thought about green technology as a way of helping steer an economy back to growth and prosper?

Well it would appear that Scotland might be doing just that, as they are trying to encourage as many as 600 companies to move into the ‘green economy’ in order to boost profitability. The green economy consists mainly of renewable energy sources, and low-carbon technologies.

Scotland seem to have recognised that there could soon be big money in this industry, hence the drive towards getting more firms into the industry.


In its attempts to become the industry leader in green technology, Scotland’s Finance Secretary, John Swinney has said that he wants to increase exports 50% by 2017 and encourage inward investment in green and low-carbon technologies.

Unemployment seems to be a problem everywhere at the moment, but Mr Swinney’s new ‘green growth’ plans are likely to create around 130,000 jobs by the year 2020.

What do you think, is Scotland taking a step in the right direction by investing in green technologies, or is is a risky option to take given the current global economic climate?

DVD Creation with Video from a Flip Camera

12 Replies Rob Boirun

Convert a Flip camera video to DVDSince the invention of portable video cameras people have been shooting video and making home movies. But now there are new hand held HD cameras such as the Flip and Vado which can shoot 720p HD video making home movies look better than ever. But what are you going to do with all that video now? The most logical and fun way to utilize this video is to create a DVD movie, and to do this you would use your Windows PC and some DVD burning software. This article will list what hardware and software to use that will make you a video master in no time at all.

Camcorder Options

The least expensive choices when it comes to shooting HD video is to use either a Flip HD camcorder from Cisco (no longer supported) or a Vado from Kodak. Both of these options are simple to use since they are a single function gadget, and usually under $200. Both shoot HD 720p video with the click of a button. It’s just as easy as taking a digital photo. Both offer on board memory for video storage, just be sure to choose a size big enough for the amount of video you are planning to shoot. Typical options come in 4GB, 8GB, 16GB, even 32GB. You can always upgrade to a better video camcorder but expect to pay upwards of $500. Now that you know what camcorder to use it on to the big machinery.

Windows 7 Is Great for Video Editing

Even though editing video on a Mac is like a dream, this article will cater to the Windows users. So with that said your Windows PC needs to be up to date with better hardware including memory (4GB is recommended), video card (CUDA enhanced), Hard Drive space (just get a 1TB already), and processor (quad core is best). Since video editing is a very processor intensive task it’s a better choice to upgrade on hardware when necessary. Now onto the fun part of creating your DVD masterpiece.

Movie Converting and Burning Software

There are plenty of choices when it comes to choosing a video converting software that will make a compliant DVD movie from your Flip video footage. The camera itself is bundled with a basic video application but the features are very limited so if you are looking to create a custom DVD with your special touches it would be best to look around for a few more editing options.

Two recommendations that I can make are to use Sothink HD Movie Maker or ConvertXtoDVD. Both are easy to use video to DVD converters but the main difference is that Sothink also supports Blu-Ray burning. This will allow you to capture and burn true HD video and retain that same resolution to the TV set. So both of these applications feature an easy drag and drop timeline where you add the videos in the order of your choosing, then select a few DVD menu design options and click the convert button. The result will be a properly formatted DVD or Blu-Ray in Sothink’s, which you can then take to your DVD/Blu-Ray player and enjoy on your TV just like a Hollywood formatted movie disc. You can review more DVD creators at burnworld.com.

Even if you don’t choose a software package like I recommend, there are plenty of other options to choose from which include more advanced authoring features for the more advanced user. But whatever you choose all video editing packages follow basically the same procedure for making your home movie, as follows.

First Add Your Video Files to the PC

Connecting the camcorder to the PC via USB or Firewire should prompt Windows to give you a few choices on what to do with the content on the camcorder. You can choose to copy directly to your hard drive or import using your authoring software of choice.

Then Edit the Video

Like I mentioned with the two recommended software choices, almost all video editing/authoring software packages use a timeline feature where you add the files in the order of your choosing. More advanced applications will even allow you to trip and crop the video giving your further control of the final outcome. In addition to this you can add text, sound effects, background music, and more to the video production. The better applications will have a preview window so you can view your changes to make sure it’s what you are looking for.

Finally, Burn to DVD

Now that you have finished adding files and editing video, it’s time to burn the production to a DVD or Blu-Ray. All software options will have a settings area for burning. This is where you will specify they type of disc to create. The more common choices are DVD, either DVD5 or DVD9 (dual layer), just choose the type based on the blank DVD’s that you have. If you want to burn to Blu-Ray be sure to use a Blu-Ray burner (sorry have to mention this because I get questions daily on why Blu-Ray won’t work in their DVD drive). There will also be a setting for the Video frame rate: in the UK and Europe “25 (PAL)” is the standard, for the USA select “29.97 (NTSC)”.

There may be more settings under an Advanced Tab, but these are the main settings to get you started. Now you are ready to select “Burn” and beginning making your DVD movie. The burn process only takes a few minutes with today’s burners.

I hope this article puts you down the right road for creating your own DVD movies from your Flip or other camcorder video.

5 Most Popular Two-Factor Authentication Security Devices

12 Replies Alan

As we had discussed before, one-factor authentication is not sufficient in order to have good security. Especially when we talk about sensitive transaction such as banking transactions, it is not secure anymore today if it were done only using username and static password.

Two-factor has to come into the IT security field to ensure that the correct person is authenticated. The items below are the five most popular methods used for any two-factor authentication.

1. Mobile OTP

Mobile One-Time Password

Mobile One-Time Password (OTP)

A very popular and cost saving method is to use a SMS gateway and send OTP (one-time password) to a mobile phone user. This method is used widely simply because everyone has a mobile phone today which means everyone can use two-factor authentication as long as the host of the application willing to invest and provide this service.

2. OTP Token

One-Time Password Token

One-Time Password (OTP) Token

OTP token works more or less the same as the Mobile OTP. The difference is that this is a separate device and the OTP can be generated immediately instead of waiting for the SMS gateway to send. As a result, it is more reliable than the Mobile OTP but additional cost needed to have this device.

3. PKI USB Token

Public Key Infrastructure Token

Public Key Infrastructure (PKI) Token

PKI USB Token offers the second best security in the market by beating off man in the middle attack such as phishing attack. However, PKI implementation needs an infrastructure where it is going to be costly. Due to the cost matter, PKI is not well known in certain countries as people will go for OTP to have the balance of security and investment cost.

4. EMV Cap OTP with Signature

Europay, MasterCard and VISA Cap One-Time Password with Signature

Europay, MasterCard and VISA (EMV) Cap One-Time Password (OTP) with Signature

EMV Cap OTP offers the best security around as it not only beats off the man in the middle attack, but also the man in the browser attack. This is simply because the user needs to sign the transaction using the EMV card reader instead of the web browser. As a result, the Trojan of the man in the browser will no longer work. The drawback is that, signing with transaction device can be a tedious thing to do. The user needs to enter correctly the recipient’s account number and the amount in order to perform the transaction successfully.

5. Out of Band Transaction Detail Verification

Out of Band

This method provides the best security similar to the above and solves as well the weakness of the EMV Cap OTP. What this method does is to send the user the details of the transaction such as the recipient’s account number, amount and the OTP code via non-internet channel such as voice call or SMS. The user will verify those details given and confirm the transaction by submitting the OTP code into the web browser. This gives great security but not anything more after that. Unlike PKI, that piece of digital certificate can do not only authentication signing, but also document signing, PDF signing or even data encryption.

Nothing is perfect in this world where everything has its good and bad. You have to clearly define what you want and I’m sure you can find the device that is suitable to you.
