So after finding an old Backtrack 5 R3 persistent USB drive I had created years ago, I booted it up to browse the content I had on it. Last time I used it, I was connected to a WEP encrypted network, but as we all know those offer weak protection and are slightly outdated for today. The tools and techniques to break WEP encryption have been around for a while and therefore WEP is rarely used these days. That being said, WPA encryption isn’t flawless, but a better alternative. I’m not going to discuss how to crack those here. Anyway, I figured I would share with you how to connect to a WPA encrypted network in Linux using the terminal and WPA_Supplicant daemon.
Normally, we use iwconfig to configure wireless networks. However, iwconfig does not support WPA/WPA2 encryption. We have to use the “WPA_Supplicant Daemon” to connect to a WPA encrypted network.
Wpa_supplicant comes pre-installed in most Linux distros (including Backtrack 5 R3, Kali Linux and Ubuntu). Since Backtrack 5 R3 is outdated, it is configured to make connecting to WEP encrypted networks easily,
Have you ever been unable to use an electronic device because the power adapter plug has gone bad? Well, worry no more, because I am going to teach you how to repair the plug. It is a common occurrence with most electronic devices, especially the ones we carry with us, such as laptops. Most of the time people wrap the cord up and eventually, over time, will cause it to fail. This is a DIY tutorial on how to fix your own plug.
I’m sure you guys have heard of Ring Video Doorbell by now, seeing as they have so many commercials, and the bell has been out for a while. If you haven’t heard of it, it’s okay, just watch the video above to get a description of the product or visit their website. It’s basically a doorbell with a camera on it, that is connected to your wireless network. Every time someone ring’s the bell, your phone will buzz/notify you that there is someone at the door. At which point you can pick up your phone, and answer (or ignore) based on who it is at your door. You can speak with the person directly through your phone as well. The best part is the person at the door can’t see you, so you can tell the you’re out somewhere. Here is the “Ring Story” (from the box):
..If not for my wife, the Ring Video Doorbell would not exist.
Inventors come up with a lot of bad ideas and she has heard them all. One night I shared my idea for reinventing the doorbell.
She loved it! Not just for the obvious convenience, but for the security of now being able to safely answer the door from anywhere. She said, “This is like caller ID for the front door.”
I hope that you enjoy the Ring Video Doorbell as much as we do, and I look forward to hearing your stories about the product. — Jamie Siminoff, Inventor
There are so many Arduino kits in the market which you can purchase. If you are new to Arduino, the choices can be overwhelming. They have kits on Amazon and kits on Ebay, but where do you get started?
I recently read a great article over at pretzellogix.net before making any recommendations. There are 4 kits the site compares:
In an earlier blog entry, I showed you how to use Xcopy. This time I will show you an even more powerful Command(CMD) line utility called Robocopy, which is short for “Robust File Copy”. The Robocopy command line utility has even more advanced options (or switches), and was apparently released to replace Xcopy in newer Windows versions. I’m running Windows 10 and I have Xcopy commmand line and Robocopy commmand line, pre-installed on both of my Windows machines.
…[Robocopy Command Line] strengths include the ability to copy all NTFS file attributes and to mirror the contents of an entire folder hierarchy across local volumes or over a network.
To see the full list of options, type robocopy /? in the command prompt. The syntax of robocopy command line is different from other copy commands in that it accepts folder names as its source and destination — meaning you cannot use *.* or ?. However, certain files can be selected. If we want to copy a file named myinfo.txt from C:\draft” to “C:\published” then we can run the following command:
I have had the Microsoft Surface RT since it first released, back in 2012, as it was given to me as a Christmas present. I was very disappointed when I found out that it utilizes an ARM processor and cannot run all the usual Windows applications. Only apps that will work on the RT are from the Windows Store (unless it’s jailbroken, but I didn’t want to do that — not worth it for a few extra applications). Even still, I have used the Surface more then I initially expected — It comes pre-installed with the basic MS Office applications (Excel, Word, OneNote, etc.) right out of the box — so it was good for note-taking. If I needed to use any actual Windows Software to perform a task (Photoshop, etc.), I can just Remote desktop into my PC using the RDP app for the Surface RT. I used my Surface more in college than my laptop because of the size–it was easier to carry around.
One major issue I had with the Surface RT was the Windows 8 start button behavior. Push the Start button and you get the following screen:
I hated clicking the Start button and getting the above screen. “What happened to the original Start button Windows is so well known for?” This is one of the reasons I never upgraded any Windows 7 desktop/laptop to Windows 8.
“XCOPY” stands for Extended Copy, and was created to add more functions then the standard copy command. If you are using Windows, it should be installed already.
XCOPY is a command used on PC DOS, MS-DOS, OS/2, Microsoft Windows, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network. — Wikipedia
Xcopy copies multiple files and folders and can create the same structure to the copied location. (Something the copy command cannot do.)
I actually wasn’t interested at all in purchasing a car dash cam. I was in the market for a Go-Pro to take some action shots. I ended up seeing the commercial for the “DashCamPro” and I figured it was pretty neat, especially for the price. But I have had experience with similar “As Seen on TV” products, and they do not generally work as advertised and/or die quick because of poor/cheap-quality materials when manufacturing. Generally the commercials market these items and make them look better then they actually are. The video quality was amazing in the commercial, but I’m sure I missed the small font, “screen images simulated” somewhere during the commercial. It seemed too good to be true:
I purchased a Dynex 32″ TV for my apartment during college. It was a really good TV, however the remote control wasn’t that responsive. The remote got worse over time, and practically became useless within a year. So instead of purchasing a new remote, I decided to open my current one up to see what was wrong with it. I figured it was either the IR receiver on the TV or the IR Transmitter on the remote control. You can also use this tutorial if your remote is very weak. If you have to be very close to the TV to change channels even with new batteries, means infrared LED is weak.

If you use Dropbox, like me, it can sometimes be annoying that it will only sync folders/files that you specifically place in the “Dropbox” folder. This can get annoying at times when you have a folder in another location that you wish to also have backed up to Dropbox, yet do not wish to move it physically. It turns out, there is a really neat trick that you can utilize to allow you to sync any folder with your Dropbox folder.
All you really need is the Windows Command Prompt.
How to Sync any folder with Dropbox:
You need to make sure you do not make any typo’s because you will have to use the Windows Command Prompt. I will first have you setup the command in a text editor, such as Notepad. (I will be using “Sublime Text” – which is practically the same thing only better.)
