Although PayPal is the most popular platform that allows people to complete different online payments, some individuals are continuously looking for some other alternatives that give them the chance to benefit from better services. The reasons behind this action are due to various issues, such as availability, terms and conditions, restrictions and so on. If you are one of these individuals, you most probably want to find out the best PayPal alternatives. In order to help you with this issue, the following list present the top available options that come along with a succinct description of their activities.

Google Checkout

Google Checkout seems to be the best possible alternative to PayPal. Recommended for all users, this option allows anyone to benefit from a series of services, which are similar to those of PayPal. Therefore, the first thing that you should know about Google Checkout is that it allows its users to complete different online transactions. If you open a Google Checkout account, you can make payments to those individuals or businesses that accept Google Checkout. There are a few important pros of this service, including the fact that it is 100% free. Additionally, the signup process is not only free but also very fast and really convenient. Google Checkout also provides a great customer service, which gets back to its customers within 24 hours. The most important drawbacks relate to the fact that it is not available on eBay, it does not provide phone support and most of its services are quite limited for the moment.

Moneybookers

Having about 3.5 million users, this service is also recommended to different individuals. A truly great thing about this service is that the number of its users shows a continuous growth, which tells us that this service will become a very strong competitor for PayPal. Similar to PayPal, this service also allows its users to send or receive money via an e-mail address. As well, the service is present on eBay, so that you can easily close different deals. The pros that relate to this service highlight a few important considerations, such as the fact that the service is available around the world; the signup process is free for all users; its interface is user-friendly; and the platform can be used for different person-to-person, person-to-business, business-to-business and even auction transactions.

AlertPay

This is another important PayPal alternative, which represents an ideal solution for those people who intend to collect payments for their businesses. Additionally, it also allows people to send money via e-mail addresses. Thus, if you want to make any online payments, send or receive money, AlertPay can definitely support all these activities. This service also comes along with some great pros, which include free signups, low fees, fast and easy withdrawing process, and strong seller and buyer protection. Its cons highlight the fact that the platform is not yet available on eBay and the customer service via phone has some truly high fees.

In conclusion, if you are searching for the best PayPal alternatives, it is important to know that the aforementioned options are a real pleasure to use. Therefore, anyone who intends to open some new accounts for completing various online transactions should definitely consider these great PayPal alternatives.

[This is a guest article by author: Srikar Srinivasula, who blogs at - GadgetDust.com ]

Bill from Youtube channel engineerguyvideo has come up with an awesome tutorial video explaining the concepts of how fibre optic cables work and how they are used to send data/messages. In this short and concise, yet very clear video ( clocking at just 5:36 minutes), the primary concepts of the working of fibre optic cables have been discussed. Have a look at the video embedded below.

The brilliance of this video lies in the fact that how he has managed to capture the intuitive facts and bare-bone concepts of what could potentially be a complex topic of discussion replete with jargon et al.
It allows viewers to quickly grasp the concepts without being bombarded with unintelligible jargon.The mark of a great teacher if you ask me. He did more than enough explanation in those 5 minutes.

And there’s one thing that comes into my mind after watching this video – TUBES, I tell you. The whole internet is nothing but a series of tubes (or maybe complexly connected in series and parallel or a different arrangement in a different dimension).

Thanks to the awesomeness of the interwebs, that we have managed to get hold of this amazing piece of sheer genius in motion. First of all, have a look at the image itself.

I call it – Trigonometry in Motion. [ Courtesy: Reddit ]

The idea here is that in the circle, if you look at the special angles i.e. 0, 30, 45, 60, 90 degrees etc. for the first positive quadrant, all these angles are some combination of 1/2 , sqrt (3)/2 and sqrt(2)/2. And these keep oscillating amongst the special angles.

Or the easy way to remember this back in the days was SOH-CAH-TOA. As in, Sin = Opposite / Hypotenuse, Cos = Angle / Hypotenuse, Tan = Opposite / Anlge.

And now let’s go for a geek nitro booster after the jump.

I call it – Harmonic motion Hyper-drive. [ Courtesy: Reddit.com]

The circular 2d figure on the bottom is Uniform Circular Motion, and the top figure is its projection into 1d space (otherwise known as Simple Harmonic Motion aka SHM). This is a great application calculus and trigonometry – note that the derivative of a sine wave is another sine wave (with the same frequency but a different phase and amplitude).

Deep stuff! Go get some beer for me now!

The new Android 2.1, more popularly known as the Android Eclair, is now available to be downloaded on the Samsung Galaxy Portal on T-mobile UK. The catch is, this upgrade is not available over-the-air (OTA), but has to be initiated by the user using Samsung’s mobile PC suite – Samsung PC Studio.

This is ridiculous, since the Android is a modified version of the Linux kernel, and at its core, is Open Source. However, for the upgrade itself, it has to be connected to a Windows PC. More on that later. For now, let’s focus on the upgrading progress. And this process took me a good 4 hours to complete, until I found the easy and shortcut way to do it. Trust me, follow this process and the upgrade is done within 15 minutes flat!

What I did wrong before:

• Installed Samsung PC Studio which was on the CD that came along with my phone.[ This is version 1.4. etc, which is an old one ]
• Connected my phone via USB cable, and opened up Samsung PCS, and hit the Upgrade button.
• It goes to download the latest install, and then on to Step 3, which is actual upgrade on the phone, and then it goes on for ages, whilst the phone keeps flashing the Samsung logo.

Here’s the right way to do it.

• Install the latest version, just to be very sure. Go to Samsung Mobile UK website, and select Samsung Galaxy Portal-> Software, and download the 1.5 version of Samsung PC Studio.
• Once installed { i.e. after uninstalling the previous version and installing this one } , connect your Samsung Galaxy Portal using the USB Cable. Mount your SD card.

• Open Samsung PC Studio, and now it should detect your phone as GTi5700, and also should show – Firmware version on your phone, and the Upgrade Firmware version.
• Hit the upgrade. First it will download the BinaryUpdate file which is the new firmware that will be eventually loaded onto your phone. Once downloaded, it will go on to Step 3 – Upgrading the firmware on the phone.
• It will ask if you have backed up your data – i.e. contacts, SMS etc. ( I hope you have. This upgrade wipes all of it clean. Data on Memory Card is untouched ). Say yes, to that, and now it will start upgrading. PC Studio will ask you not to disconnect your phone from the PC. The phone will flash a Samsung Logo whilst in this process.
• A lot of people have complained about this process taking ages to complete. I personally experienced this 4 times, when the process did not progress at all for more than an hour.
• I found this shortcut on T-Mobile’s forum, and hence, thought to give it a go. When the Samsung logo is flashing, open the back case, and remove the battery.
• PC Studio will alert you of a critical fault in your cell, and advise you to reboot your cell in recovery mode.
• To do this, press these buttons simultaneously – Volume Down + Camera + Power. When you press these buttons, the home screen will show a Blue SIM logo and a Downloading status bar.
• In the recovery mode itself, hit Next on Samsung PC Studio, and it should go back to Step 1 and Step 2 – but it gets completed pretty soon. On to Step 3 of upgrading, this time around, the progress bar on PC Studio actually shows progress, and the process takes only about a minute to be 100%, and simultaneously, the Download bar on your phone also shows the progress.
• Once this is done, PC Studio goes to finish, and advises you to download Kies, as the new Android firmware is not supported by PC Studio. Ignore it.
• Your phone reboots on its own, and now has Android 2.1. Voila!
• All you need to do now is associate your Google account as you did the first time.

The entire upgrade process took around 15 minutes for me. I know it is quite sad that when the whole world of Android phones has been busy flashing off their Froyos, the Samsung Galaxy Portal has been struggling to get the Eclair. But still, it is much better than the 1.5 Cupcake. More on that later.
Do let me know if you face any problems in this upgrade.

Yes, we have done quite a few YouTube downloading how-tos in the past. Some of them still work, some don’t. The one which continues to work is the ever-updating awesome tool – KeepVid.com. But remember the good ol’ days of the javascript bookmarklet which used to make life so much easier. Well, the bookmarklet is back again.

And it’s called – PwnYouTube. Go drag and drop it on your bookmarks bar just as I did.

PwnYouTube Bookmarklet

Now when you visit a YouTube video, on the page, when you hit the bookmarklet, the menu option appears on top of the screen. Its on a yellow background, so I don’t think you’ll miss it. For your convenience, it looks like this.

Right click, and save as shown. Voila! Easy peasy!

Else, there is another alternative. Just append ‘pwn’ before the youtube video URL.

e.g. To download video:  http://www.youtube.com/watch?v=66TuSJo4dZM, enter

http://www.pwnyoutube.com/watch?v=66TuSJo4dZM

You’ll be redirected to deturl.com, and there, you’ll find options to download it from SaveVid, YouDDL and KeepVid.

So there you go, happy downloading YouTube videos.

Google Image search is one of the most visited search engines. Be it searching for normal images we want for a project, or something we want to grace our desktop/laptop as a wallpaper. And more often than not, it is the latter. So, it is quite cumbersome when it comes to searching on Google Images for the appropriate sized – or in other words, wallpaper sized images from the huge list of thumbnails. It is a further pain to sort out by clicking on each of them to verify if they are indeed good looking images in the full size, and if they are not pixelised.

The solution: a Google Image Search hack which allows Full size image results, no thumbnails whatsoever, for your full viewing pleasure. [ as shown in the pic above]

The link is here:

Google Image Ripper » Dear Computer,.

Enter your search keyword, choose your size – which ranges from icon to xxlarge to huge. Press “Rip Google” and voila. Just be prepared to be hit by a massive wall of wallpapers. And just for your viewing pleasure, I’ll attach a massive High Definition wallpaper of Inception. Of course, this one’s a thumbnail, so do click on it to enjoy it in full HD glory.
