Google Glass

"What?"....  That was my first reaction to the first time I heard the term "Google Glass".  What might make more sense to most folks is if they called it/them "Google Glasses".

Google Glass is a "wearable computer", which incorporates an optical head-mounted display (OHMD) with voice and touch commands, and a "Bone Conduction Transducer" for sound.  A camera for stills and video is incorporated into the frame, which can give real-time photo and video (with audio) records of the wearer's point-of-view and experience.  Other terms for this "Wearable Technology" include "Augmented Reality (AR)".

The device is based on the Android OS.  Third-party developers are creating "Glassware" applications for the device.  Common tasks (apps) will be for e-mail, mapping, web searches, language translation, social networking connections, news & media, etc.  But basically, as the below TechRadar.com article put it, "The sky's the limit."

Initially, consumer release of Google Glass was scheduled for 2013, but very significant privacy issues are largely responsible for delaying its release to the general public (in 2014?).  I have a feeling though, that the Genie is out of the bottle on this one, and it is going to be hard to get it back inside.  Like so many other new technologies, this is coming, whether you like it or not.

Microsoft Anti-Trust Case... 5 Years Later

This broadcast is now over 8 years old, but there is still a lot of truth to it... and the visibility of Google and Linux is much more prominent now as well, confirming and reinforcing predictions.

This broadcast is brief, yet is sums up very well my views of Microsoft and some of the competitive products they deal with.

Linux Distros for Older PC's

Here is a way to revitalize an older PC.  Breathe some new life into it... and possibly keep it out of a scrap heap (or landfill) for just a little bit longer.

  • Is your PC grinding to a halt every time you try to use it?
  • Did you buy a "low cost" PC over 5 years ago?

What happens, especially with Microsoft Windows Operating System (MSW-OS) based PC's, is that the software gets ahead of the hardware.  Eventually the "resource" demands of updated software outstrips the hardware resources (such as RAM, and CPU power) to a point where the machine can literally grind to a halt.  The problem is not the machine hardware... the problem is the software.  Too often, the "Old Clunker" PC is still a perfectly good computer, it simply just cannot handle the new software.

Top 5 Lightweight Linux Distros @ "The Linux Site"

Using less resource hungry software is a very viable solution for getting more life out an older (and/or less expensive) PC that seems to be stuck in the mud.  There are some very resource friendly ("lightweight") versions of Linux around that usually will run quite well on a basic PC intended to run MS Windows. A good Google Search will yield a number of hits like the one above, and provide a number of choices for a "Free" alternative to buying yet another MSW based PC... and adding yet more (potentially toxic) discarded tech stuff to closets, garages, landfills, etc.

If your computer and internet use can best be described as: "I mostly surf the web and do e-mail, with some occasional 'Office App' stuff" (like Word Processing, Spreadsheet, and Presentation tasks)"... then a Lightweight Linux Distro (distribution) may just be the thing for you (and Planet Earth).  ;-)

Most basic computer operations can be done "On the Cloud" these days, so all you need really is a browser and an Internet connection (along with the hardware and OS to get you there).  An old PC with Puppy Linux for example, can get you where you need to go in most cases.  For example, with a Google ID (i.e. an e-mail account), you can have free access to a number of very sophisticated "Products", including "Home & Office" apps like Google Drive.

If you need or want to run various applications locally, odds are pretty good that you can find what you need ... still, for free.  Ubuntu-based distributions of Linux are very popular right now, so anything in that family of OS software is likely to have a healthy list of available apps to choose from.  A quick Web Search will let you know which direction you may want to go, in deciding on a Slim Linux Distro for an old PC.

What makes Linux "Free"?

Linux, and most of the apps written for it, are known as "Open Source Projects".  What this means is that there is a small army of developers out there, who collaborate as volunteers to create and improve these software applications.  Open Source applies to the fact that the "Source Code" for the software is open for all to see, and modify as they see fit.  To avoid total chaos, there is typically a controlling entity to coordinate the final release... but in general, these are all "grassroots" projects, which are developed and maintained by some very dedicated folks, who want to see the World of Computing be a better place for everyone.  It is a very "coolbeans" idea, and it seems to be working very well.

How Do I get Linux onto my PC?

This is a pretty big question for a single blog post, but a few clever Web Searches will yield lots of tips and detailed instructions regarding how to get the task done.  The good news is that in most cases, you can still keep your MS Windows OS on your PC, with Linux running alongside it.  You won't necessarily run them both simultaneously, but you can easily have the option of running one or the other.  In this case, you typically want to have MSW loaded first (which is typically how it works anyway).

Another option is to reformat the HDD (hard disk drive) and load Linux as the primary OS.  This is not a bad choice, especially if you are fed-up with Windows and Microsoft in general.

In any case, you will need to figure out "How To Burn an ISO File" to a CD or DVD.  The resulting disk will be a "bootable" disk, which will allow you to load the OS on your HDD, BEFORE MSW boots up.  All you need to be sure of is that you have enough "free space" on your HDD to accommodate the Linux installation.

You may already have a CD/DVD Burner software package on your MSW-PC.  If not, or if you are not sure, there are a number of free choices out there to get you on your way.  I suggest using CDBurnerXP... it is free, does an excellent job, and has an easy to select option ("Burn ISO Image") for getting your Linux ISO download onto a CD or DVD (usually a CD is just fine for these Slim Distros of Linux).  This an other CD Burner Choices can be found at places like Download.com - Free CD Burners ... (a C-Net.com site, which I find to be fairly reliable).

The important thing is to be patient.  The best advice I ever got was to, "Load it, try it till it breaks, and try it again."  It is a very satisfying feeling when you get it right, and you will be amazed at the speed of that "Old Clunker PC" that you wanted to toss out the window on numerous occasions.

You can also be proud of the fact that you will doing yourself, the Open Source Project world, and the Planet Earth a huge favor.  And don't forget: Have Fun with It!

Managing WiFi Networks and Connections

Wi-Fi (wireless) computer networks are convenient  but they add a significant layer of complexity and instability in the connection, and they add a far greater amount of a security risk... as opposed to a more traditional "Wired" LAN" (Local Area Network) style computer network.

Both systems central focus is a "Router".  Most common Wi-Fi routers have 4 "RJ-45" LAN cable ports on them, so they can be used as a wired network as well... they just add the antenna(s) and circuitry for the radio broadcast (Wi-Fi) part.

Unfortunately, when you radio broadcast your data (or anything for that matter), it means that anyone in range can intercept it, and possibly decrypt it.  A number of folks don't even have "secured" Wi-Fi networks.  

It is a good idea to do your homework, and know and understand something about Wi-Fi security, before you try and connect to and use a Wi-Fi network.

You should at least be able to identify if you are connecting wirelessly.  It is entirely possible to be connected both through a wired and wireless connection at the same time, so simply connecting your PC to a router with a cable does not necessarily mean that you are disconnected from the Wi-Fi part... and if the Wi Fi is not secure (or even if it is), there is a possibility that you are broadcasting sensitive information. 

https://www.google.com/search?q=wireless+network+security+protocols

The two most popular Wi-Fi Security Protocols in use today (Feb-2013) are:
WEP
WPA2-PSK  (which has several different variations)

Try reading:
The Differences Between WEP and WPA
... while the publication date is old, it is still a very easy to read article, which pretty clearly explains the differences here.  One significant nugget here is:
"Researchers in the computer science department of a German university recently demonstrated the capability to compromise a WEP-protected network very quickly. After spending less than a minute intercepting data (fewer than 100,000 packets in all) they were able to compromise a WEP key in just three seconds."
https://www.google.com/search?q=how+secure+is+a+wireless+computer+network

Even the most secure household Wi-Fi Computer Networking are not necessarily all that secure.  Some major problems in using an unsecured network include:

  • Unauthorized use of your Network by neighbors, of people on the street or in parking lots.
  • Ability of intruders on your network to access your files, data, and possibly even "secure" website connections (e-mail, banking, etc.) where you "saved" the log-in info to your browser.
  • Allowing intruders to use your unsecured (or poorly secured) PC Network to upload illegal materials to the Internet, which can be traced back to you... and could bring an agency such as the FBI knocking at your door.

So... A word to the wise... Again...
Do your homework... and know how to test that your WI-Fi network is secure.


Another good topic to followup on is:


Have fun!

Video Viewing Software

My favorite Video Viewers are:

(Both of these are apparently for the MS Windows OS only... and they are "free".)

Media Player Classic ... on CNET... for MSW

  • Runs more smoothly for me when I watch commercially produced DVD movies.
  • Has a hands capture mode, to capture a frame to a still image.


and

SM Player ... on CNET ... for MSW

  • Works well for me, except that transitions between "chapters" in commercial DVD movies are not always that good.
  • I especially like the image capture feature on this one... as it can capture a whole series of frames, which is especially handy with fast action scenes.
