Microwave ovens that you use to cook food operate at a frequency of 2.45 GHz.
This is the same radio band where one finds WiFi, Bluetooth, and so on.
So, why is everything lumped into this one chunk of the frequency spectrum? Is there something particularly magical about 2.4 GHz?
It turns out that there is a common misconception about this frequency and water.
The truth, however, is far more mundane…
So there you are, trying to view holiday photos and video from friends and family.
The files in question have the extension HEIF or HEIC, which you’ve never seen before.
No matter what you do, they just won’t open. They also don’t have a thumbnail preview in Explorer.
So how the heck do you view these things? And why aren’t they just simple JPEGs or MP4 files?
It’s everywhere these days: 2FA (two-factor authentication).
More and more, you must use something more than just a password to secure your online accounts.
Some sites, like PayPal, are apparently requiring 2FA for everyone.
So, what types of 2FA are there? Do you have to use a smartphone? Is there an alternative to SMS-based 2FA? And most importantly, is it that much safer?
Finally, I reveal the other reason why everyone is pushing 2FA so much – and it doesn’t have anything to do with your security or privacy!
Everyone has annoying technical problems.
It’s just part of Computerized Everything these days.
Usually, we tend to become aggravated when these problems occur… But what if we didn’t have to?
What if you could solve your own techie issues with a minimum amount of frustration – and in record time?
If that sounds like a plan, join me for the best techie tip yet!
Power banks, portable USB chargers, battery banks… Whatever you want to call them, they’re very handy for charging your gizmos on the go.
The only trouble is that almost all of them take AGES to recharge themselves.
Even though many models support Quick Charging of your gizmos, the power bank itself usually only gently sips juice from the wall outlet as it leisurely refills its internal lithium-ion cells.
Typically, you may have to wait upwards of 14 HOURS for a full recharge! That’s not very convenient.
Enter the RAVPower 26800mAh USB C Power Bank – with 30W quick-charging INPUT for a full recharge time of only 4 hours!
But the fun doesn’t stop there…
Just how fast is USB 3?
There seems to be a bit of confusion out there about how fast USB 3.x devices can actually go – as well as how to actually obtain those blistering-fast transfer rates.
That’s not surprising since what should be a pretty simple topic is actually quite convoluted…
You may recall my earlier video, Slow copy speeds with USB 3? No problem! 🎞
I was recently informed by one viewer that 400 MB/s is completely impossible for USB 3, so I guess it’s time for a review!
The latest news about 5G isn’t exactly flattering.
After dealing with nothing but hyped-up descriptions of the Technological Wonderland that awaited us, now even mainstream techie news seems to be all about bashing 5G instead of promoting it.
In short, reality sunk in.
I suspect we’ll see some rather substantial evolutionary changes in wireless service instead of the revolutionary changes we’ve been promised – and that’s not necessarily a bad thing!
We often hear lately about nefarious plans involving injectable tracking devices… But is such a thing even possible?
Given the current state of technology, would such a thing even work?
Better yet, HOW would it work?
After all, it’s a long way from contactless payment cards to tracking chips floating inside inside millions of people who are constantly on the move.
The answers to these questions surprised me – and they may surprise you, too!
Wireless charging is all the rage these days.
Unfortunately, it’s not quite up to par.
It turns out that most chargers are actually wasting tons of electricity – and they’re not exactly easy to use, either.
Join for me for a look at yet another wireless technology that leaves a lot to be desired…
For awhile now, we’ve been hearing rumors of anti-trust actions against the four main Big Tech companies.
Recently, the word is that actual charges will be brought starting in June of this year.
When you put all the recent stories together – along with some other interesting events involving Big Tech – it DOES look like something is finally about to happen.
But will any of it actually change anything?
It’s easy to be cynical, but I do see an opportunity here to make a difference…
