Homemade Parabolic Antenna

bandwoiewurp

Here’s an entertaining and very easy way to boost your wireless Internet signal– use a soda or beer can! In the video done by Kim Komando, she uses a beer can, but I think a soda can would do just as well. The technique is surprisingly easy, lol!

In case you are wondering, the beer can becomes a parabolic antenna. While quick and easy, I think the last thing I’d want dangling from my router is a slashed beer can. It just looks…. informal, lol. Even a fancy soda can would be a little messy-looking, I think. Instead of a can, you can use a sheet of aluminum foil wrapped around a piece of card stock paper or cardboard.

Remember When?

Oh spare me those stories of how we used to WALK 20 miles to school when we were kids– and UPHILL BOTH TIMES, even! ;) lol

Here’s a cute video I found of some little kids pondering the enigmatic memorabilia of…. two decades ago! Very cute!

Yes, those were the days….

A Review of the Mobile Edge Laptop Messenger Bag

bag9237498

I recently purchased a new laptop messenger bag for my 15.6″ Toshiba. My old neoprene bag had seen better days, and the broken zipper was no longer keeping out rain and snow. After shopping around for quite some time, I chose the “Notebook Messenger.” I like it because it’s not the typical long, briefcase-type shape, but it’s narrow and tall. These are much easier to hoist around, full of stuff. Because of the unique shape and multiple pockets, this is the best laptop bag I’ve ever owned.

It comes at a pretty penny, however. Mobile Edge sells it retail for $59.99. I paid less than that at a discount store. But even with the discount, it was still rather expensive.

I like the roomy section under the front flap. It’s a great place to hide all the computer accesories and my peppermints. :) The bag is constructed of ballistic nylon, comes in a very classy red color, and has reflective strips along the seams.

The laptop compartment has two slots divided by a non-removable soft pad. I wish the pad was removable, because then the bag could serve as a backpack-type bag, too. The straps are well done, with solid seams and a comfortable molded plastic handle. The bag is extremely roomy and has pockets for everything.

The description of the size of the bag is muddled, though. The Mobile Edge website says it fits “most laptops up to 16″ and MacBooks up to 17.” The tag on the bag says it “fits up to 15.4″ widescreen” laptops. And the discount website I purchased from said it fit up to 17″ laptops. That’s a HUGE margin, and the inaccuracy is inexcusable. The consumer MUST know what size laptop the bag is for! I took a chance, and my 15.6″ Toshiba (widescreen) just BARELY fits. BARELY. I can zip it up and that’s it. The top of the laptop is not protected by any padding, so I must be careful when I haul it around.

Pros:
Very roomy interior.
Durable nylon material.
Narrow, tall shape makes it easy to carry heavy stuff.
Good straps.
Attractive.
Lifetime warranty.

Cons:
Mislabeled laptop sizes.
Non-removable pad in laptop compartment.
Bag often flops forward; won’t stand upright unless laptop compartment is filled.
Expensive.

This is the best messenger bag I’ve had, despite the cons. Is it worth shelling out $60 for? No. Maybe half that, if you can find it. It’s a very, very nice bag, though.

Note: I was not compensated in any way for this review. I’m just reviewing it because I love to review things and I thought my readers would like to know about this product. :)

Cable Bonanza!

ether

I got a new laptop a few weeks ago, a terrific Toshiba Intel iCore3. It’s the lowest grade iCore (all I could afford), but it’s SO much better than the plain ol’ dual core machines! The Toshiba has some nice entertainment peripheral perks, too, which I am itching to try out. One is an HDMI port, for plugging in the laptop to your television. I SO want to do this! We do not have television service, just Internet. We get our news, movies, etc from the Net. I think it would be so terrific to be able to stream a video or weather forecasts or whatever to my TV, for us all to watch. Because currently, in order for us to watch anything, we have to huddle like football players around my computer monitor.

Unfortunately, my TV is “old.” It’s only 5 years old, but all it has in the back are RCA auxilliary ports and S-video port (and a coaxial post, which is useless to me). I’ve been on the hunt for some kind of converter cable to rig up between my laptop and the TV, so we can watch streaming Internet stuff. I think I found the jackpot: Optimization-World. They have everything! They even have the DVI to HDMI cables and splitters that I was looking for for my funky cross-operating system computer setup.

Looks like a cool site. I haven’t ordered from them yet, but they have great deals on the cat 5 cable (colored, too! So I can use color-coded cables instead of messing up the mangled black cables like I always do).

Geeks, check it out. ;)

QR Codes: Amazing Cell Phone Technology

matrix

This technology just blows my mind. Not that I cannot comprehend it– the basics are rather simple– but just the fact that this can be done. Remember, I can recall the days before the VCR and CD!! But anyway, there’s this amazing technology called Sparqcode. It’s a form of qr code advertising:

A QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones. The code consists of black modules arranged in a square pattern on white background. The information encoded can be text, URL or other data.

Common in Japan, where it was created by Toyota subsidiary Denso-Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. QR is the abbreviation for Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.


So perhaps you’re wondering what’s so amazing.

Well, qr codes can do anything. Let’s say a billboard has a qr code on it. You can scan that code with your smartphone, and the phone will activate something according to the data on the qr code (it may open a web page, or tweet your location, or whatever). This technology can be extremely convenient, as it does simplify mobile technology. There’s room for abuse, of course, such as tracking and etc….

If you are a business owner, you can also create your own qr codes (with SparqCode, a popular qr code management company), and track data for analytics later. It’s all just amazing to me.

Qr codes are being touted as our “mobile future.” What do you think about it? If you have a business, would you invest in this technology?

Lots of Bots

ew90085093

Yikes. According to CNet, more than 2 million computers in the the United States host botnets! Botnets are malicious programs that infect computers. They are spread through viruses and worms, and are controlled by a “master” somewhere on the Internet. Botnets spew out spam, more viruses and worms, and phishing attacks. Computers under the control of botnets are called “zombies.”

Many times, computer users are unaware that their computers are infected. Unfortunately, these innocent parties can sometimes get in trouble with the law or their ISP for spewing out spam and other filth, even if they are unaware that their computer has been programmed by someone else. I’ve heard of people being thrown into court or paying large fines for sending spam, having filthy images on their computer, or sending out worms… totally unaware that their computer was a zombie.

You can protect your computer from botnets:

  • ALWAYS install a firewall and anti-virus program– use them, and keep them updated.
  • Keep your operating system updated.
  • Be very careful of the websites you visit. Music and video sites are “risky” sites.
  • Reformat your computer every once in a while. It’s a big project, yes, but I do it once a year or so. Not only does a reformat erase everything on the hard drive, it restores the operating system back to factory settings which makes everything faster like it was originally.
  • NEVER open email attachments unless you are 100% positive you know what it is. Some bots infect email accounts, and send out mail to everyone in the contact list (including you), so a bot can disguise itself as a legitimate email from someone you know. It’s a good policy to email the sender and ask if they did indeed send an attachment before you open the attachment.

With proper security measures and clean online behavior, you can eliminate the risks of botnets.
