All about smartphone and tablet tethering

November 27th, 2016

Android USB TetherYou may have heard about tethering, but it probably seems a bit mysterious and complicated.

Tethering is when you connect your smartphone or tablet to your puter, and then use your mobile device’s data connection to surf the internet on your puter.

Well, to put it another way: your puter uses your smartphone (or your tablet’s 4G connection) as its internet connection instead of your normal DSL, cable, fiber, etc.

Tethering can be done in several ways, and it’s much easier to set up than you think!

Slow Internet? Try an unlimited satellite internet service

October 23rd, 2016

Unlimited Satellite InternetIf you live in the middle of a big city, chances are you are currently enjoying internet download speeds on the order of 100 Mbps, 200 Mbps, or even 1 Gbps in some areas.

But for the rest of us – especially those who live out in the country – it’s often nearly impossible to get any kind of good high-speed internet connection.

Sure, you may have DSL, but it’s very slow. You know the drill: “Yes, we’re upgrading our networks, running fiber everywhere, blah blah blah… Please wait 5 years.”

Well, it just so happens that there is a solution to your internet woes, but a little luck and some homework is needed!

PPI, Retina displays, and what makes a screen ‘good’

July 17th, 2016

Retina PPIIf you’ve read any reviews recently about phones, tablets, and other gizmos, you’ve probably come across a lot of talk of PPI (Pixels Per Inch) and “Retina” screens.

In short, the number of pixels crammed into a device’s screen seems to be uber-important to which gizmos get the best reviews.

But hang on a minute… Just what do these numbers mean?

Does it really matter that much?

Superglue: Everything you need to know, and some things you don’t

July 10th, 2016

Superglue: Be careful with it!Superglue is awesome.

Originally discovered in 1942 by American scientists who were trying to come up with good transparent gun sights during WWII, superglue is the “sticks to everything” goto adhesive for all your gluey quick-fix needs.

And frankly, until you’ve superglued two fingers together, you really haven’t lived…

Anyway, there’s probably a lot about superglue that you’ve never heard before. So, read on, and then you can go impress your friends with your amazing knowledge of cyanoacrylate adhesives!

The SSHD: Hybrid hard drives that are both big and fast

March 20th, 2016

SSHDYou’ve probably heard of SSDs (solid state drives). These are hard drives that use a type of very fast and very robust flash memory for data storage instead of a spinning magnetic disc.

SSDs are very fast, and until recently, their storage capacity was limited relative to old-fashioned mechanical spinning HDDs. They were also rather pricey.

You probably haven’t heard quite as much about SSHDs: hybrid mechanical hard drives with a small amount of SSD-type storage built-in. The idea here is that the SSD part of the drive can be accessed very quickly, so it acts as a very fast buffer between your puter and the slower mechanical part of the drive.

The result? SSHDs are faster than a mechanical HDD, not as fast as an SSD, but still offer 2TB, 4TB, or even more storage space – all at an affordable price.

A crash course in 4K UHD, or Ultra High Definition

January 3rd, 2016

4K for SmartiesFor awhile now, the talk of the town has been “4K”. We hear a lot about it, and you can even buy a 4K television.

On the other hand, 4K content hasn’t really hit the mainstream yet. In fact, it hardly exists at all.

We do have plenty of new TVs and Blu-ray players that have “4K” printed on them, though.

So what is this magical new format? What is 4K? What is UHD? More importantly, should you care?

How does password authentication work on web sites?

September 12th, 2015

Ashley Madison HackedI recently read an article about the Ashley Madison hack. For those of you who aren’t into cheating on your spouse, Ashley Madison is a web site where you can sign up and meet up with other lovely people in order to have an affair.

Anyway, they were recently hacked. More than 11 million passwords were obtained, and the reason why made me fall off my chair.

In short, the users’ usernames + passwords were stored in the site’s database in an MD5 hash – along side a BCrypt hash of the user’s password.

Well, what does all this mean to you?

Lithium Polymer vs Lithium-Ion batteries: What’s the deal?

June 21st, 2015

LiPo = Li-ionIf you’ve got any kind of gizmo – laptop, tablet, e-book reader, cell phone, MP3 player, cordless screwdriver or drill, etc. – then you’re using lithium-ion batteries all the time.

Lithium-ion batteries, often abbreviated as Li-ion, are extremely common these days.

But what about so-called Lithium Polymer batteries, also called LiPo or Li-poly batteries? Are they really better?

If you believe the marketing folks, yes they are. But, as it turns out, you’ve been fooled just like me!

Browser Fingerprints: What they are, how they work, and what it means to you

April 12th, 2015

Browser FingerprintYou may have heard of browser fingerprinting and its security implications. Then again, maybe not.

In either case, you probably haven’t heard the whole story.

A browser fingerprint is when, by visiting a web site, that site can generate an ID (or fingerprint) that is unique to your computer. The fingerprint can then be sent to their server, and you can be tracked.

No cookies required, no security holes required, no “Do not track me” setting can make a difference… Just plain old browsing the web will do it!

Okay, so how does this all work? And what does it mean?
