We have tried to take Webpage/Website screenshot and use it’s Thumbnail  in website worth calculator website.

This method  works for most of the websites which are hosted on Linux server except for few  java script enabled websites where it throws a error.

But for websites hosted on  windows server it works 100%  perfectly.

How to Take website screen shot in Windows Server

If you want to start your own website thumbnail generation service it is best to take windows hosting  because this software / script  works 99.99% correctly  on windows Operating System as it is an .exe file

Requirements :

Windows Hosting

PHP GD Library

Permissions to execute ".exe" files (VPS/Dedicated server is best for this)

IE must be installed (because screenshot is taken from IE only)

How this script will work in your hosting server

Thumbnail Generator software checks if it can capture particular website thumbnail or not.

If it can take the screenshot, it will be in the cache.

If not it will capture full webpage (home page of the given domain) and shows it in the IE Browser by using IECapte.exe

The images now are saved  into the folder which is specified in the script and the thumbnail would be resized by given dimensions and finally displayed in the Browser

How to Install this Script

Download IECapt and upload it to your windows hosting server

Download Website Thumbnail Generator script and unzip to the same folder where you  uploaded the IEcapt

Change the webthumb.php as  needed . You can change the cache time, thumbnail size, folder path for thumbnails etc..

Usage Example

webthumb.php?url=http://www.google.com

webthumb.php?url=http://www.facebook.com&x=150&y=150

Sample Screen shots taken by me in my PC

save all files to your PHP folder In my PC it is C:\xampp\htdocs\webthumb (I am using XAMPP)

Screenshot of files in that folder

Modify webthumb.php to use it in your PC as like below:

script changes

open your browser and copy/type this path

"http://localhost/webthumb/webthumb.php?url=http://www.google.com"

Check the cache folder.Full size thumbnail image will be saved in that folder (in my System i have created cache folder in “C:/webthumb/cache”

thumbnail screen shot

We will see in next post how to take website screen shot in Linux Server

The Best Web-based OCR Services

Most scanners ship with some sort of OCR software but if you don’t have a scanner, you can simply capture a photograph of the printed text with your digital camera or even your mobile phone and then use an online OCR utility to extract text out of that image.

Meet the best online OCR services that can help you convert images into text.

1. Google Docs – When you upload an image file or a scanned PDF to Google Docs, check the option that says “Convert text to Google Docs format” and Google Docs will automatically perform OCR on the file before saving it to your account.

If the OCR operation is successful, all the extracted text is stored as a new document else Google Docs will store your original image without any modification.

With Google Docs, you can perform OCR on images and PDFs as large as 2 MB, the text recognition accuracy is quite impressive and there are no limits on the number of files that you can process in a day. However, Google Docs won’t retain the original formatting of the document and the OCR engine almost fails with low-resolution images.

2. Abbyy FineReader – FineReader Online is a web-based OCR service that can instantly convert your PDF files and images into corresponding office file formats. This is an Abbyy service and therefore the character recognition accuracy is quite good.

Unlike the OCR engine in Google Docs that can only recognize printed text written Latin characters, FineReader can understand a much wider variety of languages. It even works with multilingual documents that have text written multiple languages.

A free account at FineReader Online will only let you convert a handful of images to text and you’ll have to shell out around $3 per 10 pages for additional conversions.

3. OnlineOCR.net – Online OCR, as the name suggests, is a cloud based OCR service that can handle all common images formats including scanned PDFs. If you have multiple images that you would like to convert to text in one go, you can put them all in a single zip file and upload it to Online OCR.

Of all the OCR services that I have tried so far, Online OCR has impressed me the most. The character recognition accuracy is quite good and the converted documents look like a replica of the original images. In my limited test with three different types of images, Online OCR was able to preserve the structure and formatting after the conversion in all the three case.

Like FineReader, Online OCR offers credits for converting around 5-6  images to text for free and after the limit is over, you’ll have to pay around $4 per 50 pages.

4. FreeOCR.com – If you ever need to extract plain text from an image or a scanned PDF file, Free OCR may be worth a try. The service requires no registration and you can handle up to 10 image uploads per hour.

Free OCR is like a graphical front-end for Google’s Tesseract OCR engine that is often considered as one of the most accurate text recognition engines around. However, Tesseract supports only a limited number of languages and it ignores most of the formatting of the scanned image.

5. OCR Terminal – OCR Terminal is one of the most mature online OCR services out there that not only supports images and scanned PDFs but even software screenshots.

For instance, if you ever get an error message on your computer, capture a screenshot, upload the image to OCR terminal and it will return you the entire error in plain text that you can copy-paste in emails or online forums.

OCR Terminal is internally powered by Abbyy’s OCR engine. A free account with OCR Terminal gets you 20 free conversions every month and you can pay around 7-9 ¢ per additional conversion.

6. OCR Online – Like FreeOCR, OCR Online doesn’t require any registration and you can translate up to 100 images to text in a single day. It also supports a large number of languages.

OCR Online offers good recognition accuracy and preserves most of the original formatting but what you’ll like most about this service is batch processing. You can upload a large number of files in one batch and it will output the results as one document.

Online OCR Software – A Comparison

[*] One obvious downside will all the above mentioned OCR software is that they work only with printed text, they cannot recognize characters from hand-written text.

How to Measure your Site Performance
Google offers a free tool called Page Speed that you may use to improve the performance of your web pages. The tool performs several tests against your website and then suggests simple ways to make your site even faster.

YSlow from Yahoo! is another such tool that measures the performance of your pages and offers suggestions for improvement. Yahoo! says that the response time of web pages can be improved by 25% to 50% by following the recommendations made by the tool.

Run Page Speed and YSlow Online
Both Page Speed and YSlow are available as add-ons for Firebug and will therefore only work if you have Google Chrome or Firefox on your computer.

If you are however running a different browser (like IE) or would like to evaluate the performance of your sites without installing add-ons, you should give GTMetrix a try.

GTMetrix will analyze your pages using both Page Speed and YSlow rules in one go and other advantage is that it runs online without requiring any add-ons.

You can setup a free account and the service will automatically run performance tests against your site at pre-defined intervals. It also preserves the reports of previous tests and you can therefore easily measure the outcome of your optimization efforts over time.

Is your ISP is limiting your download speeds?

You can run the Glasnost test in your browser to determine whether or not your ISP is following any such tactic to manipulate your download speeds for specific sites.

The test uses a Java applet to compare your regular download speed against the speed at which Flash videos get streamed to your system. Other than videos, it can also compare the download speed for email attachments (via POP and IMAP), normal HTTP based file transfers, torrents and binary downloads from Usenet servers.
You should consider running these tests at different times of the day since some ISPs may be limiting speeds only during peak hours. Also, do remember to stop any other downloads that might be running in the background for more accurate results.

Merge Multiple Bookmarklets into One

Your bookmarklet collection is growing everyday but if you are looking to trim it down, try Quix. It is a powerful bookmarklet that combines the functions of multiple bookmarklets into one and works just like the command-line in Unix – you hit the bookmarklet button and it will open a dialog box where you can type a command.

For instance, if you say bitly, it will shorten the address of the current web page using bit.ly while a command like tr will automatically translate the page into your language using Google Translate. Easy to remember commands like s, w and yt will help you search Twitter, Wikipedia and YouTube respectively while you can always extend that list with your own custom commands.

Ubiquity for Firefox and Quicksilver on Mac offer similar functionality but what interesting about Quix is that you may also use it on your iPhone and iPod Touch.

To learn more about the Quix bookmarklet, check this video screencast by Joost de Valk, the developer.

Recently, while playing with my Acer Aspire One A110 netbook, I tried installing Windows 7 on it. Since it doesnt have any CD drive, I had to create a bootable windows 7 USB stick in order to install it on my netbook.

There are several applications i.e Ultimate Multiboot, that can make your USB bootable and even configure it to boot with Windows XP, Vista etc. But it didnt support the latest upcoming OS by Microsoft, Windows 7.

A Bootable USB is a free application to create bootable Windows 7 USB. There are lots of online tutorials to do this manually, but it always better if an application does it all automatically.

The process of this tool can be explained in just 4 easy steps!

* Check USB drive
* Format USB drive
* Choose DVD or ISO image
* Start the process

Download A Bootable USB

You can create bootable Windows 7 USB by downloading A Bootable USB from here: Download A Bootable USB.

Wireless Networking (Wi-Fi) has made it so easy for you to use the computer, portable media player, mobile phones, video game consoles, and other wireless devices anywhere in the house without the clutter of cables.

With traditional wired networks, it is extremely difficult for someone to steal your bandwidth but the big problem with wireless signals is that others can access the Internet using your broadband connection even while they are in a neighboring building or sitting in a car that parked outside your apartment.

This practice, also known as piggybacking, is bad for three reasons:

* It will increase your monthly Internet bill especially when you have to pay per byte of data transfer.
* It will decrease your Internet access speed since you are now sharing the same internet connection with other users.
* It can create a security hazard* as others may hack your computers and access your personal files through your own wireless network.

*] What do the bad guys use – There have been quite a few instances where innocent Internet users have been arrested for sending hate emails when in reality, their email accounts where hacked though the unsecured Wi-Fi networks that they had at home. Wireshark is a free packet sniffing tool for Linux, Mac and Windows that can scan traffic flowing though a wireless network including cookies, forms and other HTTP requests.

How to Secure Your Wireless Network

The good news is that it is not very hard to make your wireless network secure, which will both prevent others from stealing your internet and will also prevent hackers from taking control of your computers through your own wireless network.

Here a few simple things that you should to secure your wireless network:
Step 1. Open your router settings page

First, you need to know how to access your wireless router settings. Usually you can do this by typing in 192.168.1.1 into your web browser, and then enter the correct user name and password for the router. This is different for each router, so first check your router user manual.

You can also use Google to find the manuals for most routers online in case you lost the printed manual that came with your router purchase. For your reference, here are direct links to the manufacturer site of some popular router brands – Linksys, Cisco, Netgear, Apple AirPort, SMC, D-Link, Buffalo, TP-LINK, 3Com, Belkin

Step 2. Create a unique password on your router

Once you have logged into your router, the first thing you should do to secure your network is to change the default password* of the router to something more secure.

This will prevent others from accessing the router and you can easily maintain the security settings that you want. You can change the password from the Administration settings on your router settings page. The default values are generally admin / password.

[*] What do the bad guys use – This is a public database of default usernames and passwords of wireless routers, modems, switches and other networking equipment. For instance, anyone can easily make out from the database that the factory-default settings for Linksys equipment can be accessed by using admin for both username and password fields.

Step 3. Change your Network SSID name

The SSID (or Wireless Network Name) of your Wireless Router is usually pre-defined as “default” or is set as the brand name of the router (e.g., linksys). Although this will not make your network inherently* more secure, changing the SSID name of your network is a good idea as it will make it more obvious for others to know which network they are connecting to.

This setting is usually under the basic wireless settings in your router settings page. Once this is set, you will always be sure that you are connecting to the correct Wireless network even if there are multiple wireless networks in your area. Dont use your name, home address or other personal information in the SSID name.

[*] What do the bad guys use – Wi-Fi scanning tools like inSSIDer (Windows) and Kismet (Mac, Linux) are free and they will allow anyone to find all the available Wireless Networks in an area even if the routers are not broadcasting their SSID name.

Step 4. Enable Network Encryption

In order to prevent other computers in the area from using your internet connection, you need to encrypt your wireless signals.

There are several encryption methods for wireless settings, including WEP, WPA (WPA-Personal), and WPA2 (Wi-Fi Protected Access version 2). WEP is basic encryption and therefore least secure (i.e., it can be easily cracked*, but is compatible with a wide range of devices including older hardware, whereas WPA2 is the most secure but is only compatible with hardware manufactured since 2006.

To enable encryption on your Wireless network, open the wireless security settings on your router configuration page. This will usually let you select which security method you wish to choose; if you have older devices, choose WEP, otherwise go with WPA2. Enter a passphrase to access the network; make sure to set this to something that would be difficult for others to guess, and consider using a combination of letters, numbers, and special characters in the passphrase.

[*] What do the bad guys use – AirCrack and coWPAtty are some free tools that allow even non-hackers to crack the WEP / WPA (PSK) keys using dictionary or brute force techniques. A video on YouTube suggests that AirCrack may be easily used to break WiFi encryption using a jail-broken iPhone or an iPod Touch.

Step 5. Filter MAC addresses

Whether you have a laptop or a Wi-Fi enabled mobile phone, all your wireless devices have a unique MAC address (this has nothing to do with an Apple Mac) just like every computer connected to the Internet has a unique IP address. For an added layer of protection, you can add the MAC addresses of all your devices to your wireless router settings so that only the specified devices can connect to your Wi-Fi network.

MAC addresses are hard-coded into your networking equipment, so one address will only let that one device on the network. It is, unfortunately, possible to spoof a MAC address*, but an attacker must first know one of the MAC addresses of the computers that are connected to your Wireless network before he can attempt spoofing.

To enable MAC address filtering, first make a list of all your hardware devices that you want to connect to your wireless network**. Find their MAC addresses, and then add them to the MAC address filtering in your router administrative settings. You can find the MAC address for your computers by opening Command Prompt and typing in ipconfig /all, which will show your MAC address beside the name Physical Address. You can find the MAC addresses of Wireless mobile phones and other portable devices under their network settings, though this will vary for each device.

[*] What do the bad guys use – Someone can change the MAC address of his or her own computer and can easily connect to your network since your network allows connection from devices that have that particular MAC address. Anyone can determine the MAC address of your device wireless using a sniffing tool like Nmap and he can then change the MAC address of his own computer using another free tool like MAC Shift.

Step 6. Reduce the Range of the Wireless Signal

If your wireless router has a high range but you are staying in a small studio apartment, you can consider decreasing the signal range by either changing the mode of your router to 802.11g (instead of 802.11n or 802.11b) or use a different wireless channel.

You can also try placing the router under the bed, inside a shoe box or wrap a foil around the router antennas so that you can somewhat restrict the direction of signals.

Apply the Anti-Wi-Fi Paint – Researchers have developed a special Wi-Fi blocking paint that can help you stop neighbors from accessing your home network without you having to set up encryption at the router level. The paint contains chemicals that blocks radio signals by absorbing them. “By coating an entire room, Wi-Fi signals cant get in and, crucially, cant get out.”

Step 7. Upgrade your Router firmware

You should check the manufacturer site occasionally to make sure that your router is running the latest firmware. You can find the existing firmware version of your router using from the router dashboard at 192.168.*.
Connect to your Secure Wireless Network

To conclude, MAC Address filtering with WPA2 (AES) encryption (and a really complex passphrase) is probably the best way to secure your wireless network.

Once you have enabled the various security settings in your wireless router, you need to add the new settings to your computers and other wireless devices so that they all can connect to the Wi-Fi network. You can select to have your computer automatically connect to this network, so you wont have to enter the SSID, passphrase and other information every time you connect to the Internet.

Your wireless network will now be a lot more secure and intruders may have a tough time intercepting your Wi-Fi signals.

Who is Connected to your Wireless Network

If you are worried that an outsider may be connecting to the Internet using your Wireless network, try AirSnare – it a free utility that will look for unexpected MAC addresses on your Wireless network as well as to DHCP requests. Another option is that you open your router administration page (using the 192.168.* address) and look for the DHCP Clients Table (it under Status > Local Network on Linksys routers). Here you will see a list of all computers and wireless devices that are connected to your home network.

*It is also a good idea to turn off the router completely when you are not planning to use the computer for a longer period (like when you are out shopping). You save on electricity and the door remains 100% shut for wireless piggybackers.

**If you ever want to let a new device connect to your network, you will have to find its MAC address and add it to your router. If you simple want to let a friend connect to your wireless network one time, you can remove his MAC address from the router settings when he or she leaves your place.

The hacker tool, dubbed DECAF, is designed to counteract the Computer Online Forensic Evidence Extractor, aka COFEE. The latter is a suite of 150 bundled, off-the-shelf forensic tools that run from a script. Microsoft combined the programs into a portable tool that can be used by law enforcement agents in the field before they bring a computer back to their forensic lab. The script runs on a USB stick that agents plug into the machine.

The tools scan files and gather information about activities performed on the machine, such as where the user surfed on the internet or what files were downloaded.

Someone submitted the COFEE suite to the whistleblower site Cryptome last month, prompting Microsoft lawyers to issue a take-down notice to the site. The tool was also being distributed through the Bit Torrent file sharing

This week two unnamed hackers released DECAF, an application that monitors a computer for any signs that COFEE is operating on the machine.

According to the Register, the program deletes temporary files or processes associated with COFEE, erases all COFEE logs, disables USB drives, and contaminates or spoofs a variety of MAC addresses to muddy forensic tracks.

The hackers say that later releases of the program will allow computer owners to remotely lock down their machine once they detect that it has fallen into law enforcement hands. The hackers, however, have not released source code for the program, which would make it easy for anyone to see if the program contains malware that might also harm a computer or allow the attackers to take control of it.

Update: The developers of DECAF have taken issue with Threat Level referring to them as hackers. Were just two developers who support the free flow of information and privacy, one of them wrote Threat Level in an anonymous e-mail. You could say were just average joes
