Previously I wrote about finding shared resources and files on your local network using SoftPerfect Network Scanner . In this post I am going to write about how to properly share files on local network. Unlike Windows XP where you could easily share a file just by going to its properties and checking the Share Folder option, in Windows 7 you’ll have to make sure that Everyone has Read access on the folder. Otherwise you’ll encounter permission problems like below. First of all you’ll have to make sure that you have turned on network discovery and file sharing from advanced sharing option for whatever profile you may uning for your network. Go to the properties of the folder you want to share by right clicking on the folder and selecting properties. Then go to Sharing Tab and then click on Advanced Sharing. Check on the option of Share this folder. Now go back and select Security tab on the folder properties. Click on Edit and the select Add. In the opened window type “Everyone

In colleges and other big organisations people share files through Windows File Sharing option within their homegroup/workgroup. One irritating problem one a has to go through is that while not all people may have a folder to share but the windows Network locations will show all the devices connected. On opening these computers one encounters Network Password error. One may have turned on sharing but the shared folder might have restricted access. So it is a a very painful experience to browse through the network pc’s. SoftPerfect Network Scanner  is a Network Scanner that does the job of finding connected devices on your LAN and displaying all the shared resources. Key Features:— Pings computers and displays those alive. Detects hardware MAC-addresses, even across routers. Detects hidden shared folders and writable ones. Detects your internal and external IP addresses. Scans for listening TCP ports, some UDP and SNMP services. Retrieves currently logged-on users, configured

In many modems there is no support of sending USSD commands to check balance, usage etc.. Most of the times the modem’s dashboard does not have a support for sending USSD command. Most of the 3gpp compliant modem can send USSD commands. You can send USSD commands either directly through AT commands or via third party software. You can also try to upgrade your Dashboard if the manufacturer may have added support later on. I’ll be showing you to send USSD command via a software called MWCONN . It support many modems of leading manufacturer’s by default. If it doesn’t support then you will have to  manually send them. <1> Find the com port of your modem. Go to Device Manager Settings from Control Panel, Click on  Modem to check the properties of your current modem, and then Select the modem tab. Here you’ll find the COM port your modem is using as shown in the image. <2> Now download and open the MWCONN folder. Find and run config.exe from the folder. Go to the device tab

Greasemonkey is a Mozilla Firefox extension that allows users to install scripts that make on-the-fly changes to web page content after or before the page is loaded in the browser (also known as augmented browsing ).

GitHub is a web-based hosting service for software development projects that use the Git revision control system. GitHub offers both paid plans for private repositories, and free accounts for open source projects. GitHub is the most popular Git hosting site, and the most popular open source hosting site. Git became very popular due to its awesome documentation and numerous extra free resources — like Scott Chacon’s Pro Git book — which explain Git in great detail. But these are not interactive and you have to install software, learn all the commands. You are pretty much on your own to figure out what’s happening. Try Git is initiative of CodeSchool and GitHub. Try Git will help you learn the basic of using GitHub. There is no need to install GitHub software because it works right away from the browser. It has a command line prompt, paired with step-by-step instructions and a visual representation of a Git repository, along with some tips and tricks for figuring out Git. The Try

If you work with multiple windows open in background, you must have spent a lot of time switching back and forth between them even for simple tasks like copying files or comparing text. You can save a lot of hard work of switching back and forth by cascading them or stacking or displaying them side by side. Cascade , puts windows in a single stack that has been fanned out . Stacked , puts windows in one or more vertical stacks . Side by side , places all open windows , in a side by side arrangement so you can see all the windows at once. Arrange windows in a cascade (left), vertical stack (center), or side-by-side pattern (right) You can do this easily by Right Click on empty area on Taskbar and choosing the arrangement you want. You can also snap an open window to Left/Right side by using the Windows logo key +Left Arrow or Windows logo key +Right Arrow

If you have a Nvidia graphics card in your PC, and if it supports Nvidia 3D Vision, you’ll have some .jps images in your Pictures folder. If you opened them on a non 3d screen you’ll encounter a error as shown below. .jps is extension for JPEG Stereoscopic images. It usually contains one image of double width, representing two images of identical size in cross-eyed side-by-side arrangement. To open .jps files you can simply change the extension to .jpg and open them in your regular Image Viewer like Windows Photo Viewer. You can also drag and drop them in other photo editing tools like IrfanView or XnView without changing the extension. The image you will see, will essentially be like below on a non-3D screen.

AT is abbreviation for ATTENTION. AT commands are used for controlling the modem directly. These commands are derived from Hayes Modems commands which were in use few decades earlier. You can use AT command to do specific task which your Modem’s dashboard does not allow you to do. For example sending USSD command to check prepaid balance. Dashboard just act as interface between you and the modem. You can use AT command to do some common tasks:—  1. Obtain info about device and SIM. 2. SMS/MMS services. 3. Data Services. 4. Voice Services. To send AT command you need to have the manual of the modem, and remote shell client like PuTTY. Here is nice and detailed instruction to send AT commands to your modem. http://3g-modem.wetpaint.com/page/common+AT-commands You’ll need to find AT commands specific to your modem.

You might have come across videos that have their audio out of sync. And if it is a movie you will probably don't want to delete that file. Well there is an easy way to fix that using VLC. It is also possible to fix out out of sync subtitles using VLC using same procedure. Figure out the lag of the audio/subtitle. Then navigate to Tools >  Track Synchronization. Alternatively   you can use Ctrl + E shortcut. In the pop-up windows that opened, adjust the settings according to the lag. If the subtitle/audio is lagging behind the video, the value would be negative. For example the lag is 3 seconds after the video, the value you would fill be –3.000 s. After you have adjusted the settings, hit the Refresh button. And you are done. There is also shortcut keys for the above job, but they aren't as precise. They move the audio back or forth by 50ms. There are also cool features in VLC that you might like. Play in ASCII mode: —> Open VLC media player and click on Tools>Prefe

Stop the Internet Explorer 9’s pop-up message that says “Speed up browsing by disabling add-ons’. There are few ways to do this, but choosing the “Ask me later” button just delays the pop-up for 24 hours. You  can also click on the arrow to the right of the button and select “Don’t disable”. This will stop the pop-up for a month, which is better than seeing it every day. For a more convenient solution, click “Choose add-ons”. In the window displayed, the timer at the bottom lets you choose how much time add-ons have to load. Setting it to the longest time(10 seconds) will stop the pop-up as long as you don’t have any add-ons that take longer than this to load. You can also disable or enable any add-on later from Manage Add-ons in the Tools Menu present at upper right corner of IE.

Want to know if your Mobile service provider has been capping your speed. Here is a tool which lets you check that. MDMA — Mobile Data Monitoring Application You can use this application instead of your regular modem dashboard. It also shows many other information that are usually hidden from you. In the Signal section following things are shown. On the left is the Received Signal Strength Indicator (RSSI) in dBm, measured between -113dBm and -51dBm. Next is your operator's Mobile Country Code (MCC) and Mobile Network Code (MNC). Next is your operator's long alphanumeric name. Depending on device and SIM card, this information might not be available. On the right is the Radio Access Technology; GPRS, EDGE, 3G, HSDPA, HSUPA or HSD+UPA (High Speed Downlink and Uplink). It is normal for the HSxPA indicators to only appear while data is being transmitted, while the connection is idle, 3G is displayed. Below this is a bar graph indicating the signal strength. The next line of inform

WebGL is a standard specification that is currently being developed to display 3D graphics in web browsers. The WebGL allows you to enable accelerated 3D graphics hardware on websites. Due to security reasons Firefox does not enable WebGL by default. The problem is not in Firefox but many drivers and Graphics cards do not have the full support for OpenGL . The reason it works on Chrome right now is because chrome doesn't have white/black/block-lists currently, as FireFox has. Mozilla blacklists specific GPUs based on the driver version number, i.e. NVIDIA cards require a driver numbered 8.17.12.5721 or greater AMD/ATI cards are 8.741.0.0 or greater Intel cards normally require 6.14.11 on XP, 7.15.10 on Vista or 8.15.10 on 7 (although some products are completely blocked) Macs require OS version 10.6 or newer To check if your graphics card is supported or not type following in address bar in your FireFox about:support Scroll down to Graphics Section and look for WebGL rendere
