This project lets you conveniently connect any computer with USB ports directly to a simple, traditional connector the 9-pin RS-232,It converts the electrical signals from a USB<–>serial TLL convertor to the RS-232 standard. So in a nutshell,it converts a USB port into a standard but basic serial port.
The voltage level adaptor is a MAX3232 from Maxim. This industry-standard part comprises two transmitters and two receivers, ideal for our USB<–>serial convertor, which itself offers the four fundamental signals of an RS-232 standard port, namely TXD (Transmit Data), RTS (Request To Send), RXD (Receive Data) and DTR (Data Terminal Ready).

There you go....

I am not sure this is already posted, only yesterday I came to know about this, so thought will share with you all.

Follow these steps:

1) Open Notepad and copy the contents of the code below.


2) Change the password by replacing change to your desired password in the code above with your desired password.

3) Save it as FL.bat and close. (Note: Try to be innovative and save it in such a way that it sounds like a system file so that nobody will try to bother clicking it)



4) Double click run FL.bat.

5) It will create a new folder called ‘MyPrivateLocker’ automatically. (If you want the file name to be different, replace MyPrivateLocker in the code above with the name of your choice). This new locker folder will be created in the same folder/drive as the .bat file).




6) Copy/place the files to be locked and hidden inside the MyPrivateLocker



and double click run FL.bat, it will ask whether you want to lock. Say ‘Y’ and now your folder will get locked and hidden.



7) To unlock and unhide the folder, double click run FL.bat again and enter your password you have changed in the code (step 2).



Tested for invalid password : Gave error

If you have upgraded your Laptop from Windows Vista/XP to Windows 7 some of us will find our laptop batteries not charging. I’ve been the unfortunate to have two laptops (Dell and an Acer) do the same. While there is no official word from Microsoft about the problem, there has been a lot of Microsoft Technet forum users complaining of this issue and there are couple of fixes one can try before replacing the batteries or A/C power adapters.

1. Uninstall and Reinstall Microsoft ACPI-Compliant Control Method Battery
Reinstalling the “Microsoft ACPI-Compliant Control Method Battery” has solved the problem for some of the users. To do so,
1. Start – Control Panel – Hardware and Sound – Device and Printers – Device Manager.
2. Expand Batteries
3. Right-click “Microsoft ACPI-Compliant Control Method Battery” and click Uninstall.
4. Now, click Action menu and select “Scan for Hardware changes”. This should identify and reinstall the component.

If this doesn’t solve the problem try the following:
2. Reinstall Battery
Close all the running applications and any open files to avoid any data loss.
1. While the laptop is still powered ON and connected to A/C power. Close the laptop lid and unplug the battery.
2. Open the lid and pull the A/C power off. This should power off the laptop.
3. Close the lid again and plug the battery back in.
4. Open the lid again and connect the power adapter and turn on the laptop.
This should get battery charging! If still no good, then contact the hardware vendor. I’ve managed to fix my both laptops with the above procedure.

If you use Internet Explorer and you have trouble downloading more than 2 files from one website, this registry edit might solve your problem.
To do this, open the Registry Editor by entering “regedit” (without the quotes) in the Search box on the Start menu. When regedit.exe displays in the results, click on it or press Enter when it’s highlighted.

If the User Account Control dialog box displays, click Yes to continue.
NOTE: You may not see this dialog box, depending on your User Account Control settings. See our post, Windows 7 – How to configure UAC (User Account Control), for more information.

Navigate to the following key in the tree on the left.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

Right-click on the Internet Settings key and select New | DWORD (32-bit) Value from the popup menu.

Name the new value MaxConnectionsPerServer and then double-click on it.
NOTE: This key sets the limit for HTTP 1.1 servers, which is normally supposed to be 2.

On the Edit DWORD (32-bit) Value dialog box, enter 4 in the Value data edit box, select Decimal as the Base and click OK.

Create another new DWORD (32-bit) Value under the Internet Settings key and name it MaxConnectionsPer1_0Server. Double-click on the new key and change its value to 8.
NOTE: This key sets the limit for HTTP 1.0 servers, which is normally supposed to be 4.

Close the Registry Editor by selecting Exit from the File menu.

You can set these two keys to higher numbers if you want, but if you set the numbers too high, you may find that your browsing becomes much slower than usual, and you might even get blocked from some servers for using too many connections. It’s usually safe to double the default values.
To revert to the default values, simply delete the two keys you added to the registry.

Drupal 6

You can run the following query directly in the drupal database to reset the password of user 1 to whatever you wish to set

UPDATE users SET password=MD5('whatever-password-you-wish-to-set')
WHERE uid = 1;

Drupal 7

The query is not quite the same in Drupal 7 as there is salt used in Drupal 7 and you need to put in a bit of extra effort to get the password hash. First you have to get the password has to be used. You can do this by running

./scripts/password-hash.sh the-new-password

from the root of your drupal installation. This will output the password hash in your terminal. Copy this hash. Then run the following query in your database

UPDATE users SET password='password-hash' WHERE uid = 1;

where password-hash is the has you got when you ran the script given earlier.
The assumption is that you have access to the Drupal database. If you don't have access to the Drupal database but still wish to login as user 1 you should check out our article on how to login as user 1 to your Drupal database. Again the assumption is that you have ftp access and that you are authorized to do so. If you are not then probably you are not doing it right.

If you’re an administrator of a computer with multiple users, it can be a hassle having to give permission to certain users to perform tasks above what their user privileges would normally grant them. For instance, maybe a user wants to be able to install programs from the Terminal or via the Synaptic package manager. Using “dpkg” or “apt-get” or “synaptic” from the Terminal all require Administrator privileges, which normal (non-Administrator) users don’t have.
Instead of the Administrator being required to grant privileges each time it is requested, it’s possible to allow certain users to use certain programs without requiring a password. This doesn’t mean a typical user can do any task requiring a root password, but simply those he or she is authorized. How do we do this? We simply edit a particular file.
First, open up the Terminal.
Now type sudo visudo.
You’ll be asked to enter your password.
We’ll be entering all of our edits at the end of the file, so scroll all the way to the bottom. You should now see something similar to this.
To allow a user to run a certain program as root without a password, you’ll need that person’s username, as well as the path to the program’s binary.
Let’s say we want a user named “ericcflem” to be able to install programs using “apt-get” but don’t want to make “ericcflem” a full Administrator. We can allow “username” access to “apt-get” and only “apt-get” by typing ericcflem ALL = NOPASSWD: /usr/bin/apt-get at the end of the file, as shown below.
Now simply hit Ctrl-x to close the program, then hit y when you see this prompt. This tells the computer to save your changes (typing n would tell it you don’t wish your changes to be saved).
You will then be asked (in the following prompt), to type a name and location for the saved file.
Simply hit the Enter key, which will save the file with the same name and location as the original.
In our example, we chose our own username to be the one able to run “apt-get” without entering a password, as it’s our personal computer, and not having to enter a password saves time. To see that it worked, we decided to install a program (in this case we installed gPodder, a podcast client) via the Terminal, by using the sudo apt-get install gpodder command.
As you can see in the following screenshot, we were never asked for a password.
Success! Obviously, giving any random user the power to perform potentially dangerous tasks is something you won’t want to do without serious thought. However, for some users, or for some tasks, this should be an easy way to make certain tasks just a bit more convenient.

Here’s a quick post for those looking to change the location of the downloads folder in Google Chrome. You may want to do this for many different reasons, but for most people, it’s probably because you are running out of space on your local hard drive. I moved my downloads folder to my NAS (Network Attached Storage) device. Since it’s on the network and always connected, I don’t have to worry about it suddenly getting disconnected.
I’ll talk about what happens if you do change the location to an external hard drive that can occasionally become disconnected. First let me show you how to actually change the download location in Chrome. First, click on the wrench icon at the top right and click on Settings.

Then scroll down to the bottom and click on Show advanced settings.

Now scroll down more until you get to the Downloads section.

Go ahead and click on the Change button and choose a new location. Like I mentioned before, you can choose an external drive, a shared folder, a network drive, etc to save the downloads too. There really is no restriction. Now if the download target suddenly disappears, i.e. you unplug the external hard drive, etc, then what happens?
Well, I was hoping that it would default back to the default location when you first install Chrome, but it doesn’t. Instead, the Save As dialog pops up and you have to choose a new location for the file.

And that’s pretty much it! If you have any other questions about Chrome, feel free to post a comment. Enjoy!

Internet Explorer 9 recently was having some strange issues on my Windows 7 machine and instead of spending hours trying to figure out what was causing the problem, I decided I would just reinstall the whole thing! Well, it fixed my problem and that’s why I’m writing about it.

Method 1 – Windows Features

Depending on your version of Windows 7, you have either IE 8 or IE 9 installed by default. You can uninstall and reinstall IE now by simply going to the control panel. In the Control Panel, just click on Programs and Features.

Next, click on the Turn Windows Features On and Off link located in the left-hand pane.

In the dialog, simply uncheck Internet Explorer 8 or Internet Explorer 9.

You’ll get a message stating that doing so could affect other programs, blah, blah. Don’t worry about it, it won’t do anything. Just click Yes.

Now go ahead and reboot your computer and then come back into the same dialog and re-check Internet Explorer. It will reinstall it and hopefully any issues you were having will be gone.

Method 2 – Installed Updates

There’s also a second way to reinstall Internet Explorer in Windows 7. Instead of clicking on Turn Windows Features On and Off in the Control Panel screenshot above, click on View Installed Updates.

Now scroll down the list to the Microsoft Windows section and there you will find Internet Explorer:

Click on that and then click the Uninstall button that shows up at the top. Then to reinstall IE 9, you can go to the IE 9 homepage and download it:
http://windows.microsoft.com/en-US/internet-explorer/downloads/ie-9/worldwide-languages
I’m not 100% sure about the difference in using one method over the other, but you can try both if you find one method does not fix your problem. If you have any questions, feel free to post a comment. Enjoy!
