We hear a lot about A.I. – artificial intelligence – these days. But is it really here?
Should you be worried about Skynet and terminators and some little punk named John having to grow up and save the world?
Not quite. At least not yet, anyway…
While so-called machine learning algorithms are insanely powerful these days, they aren’t really true AI.
Then again, we keep changing out definition of AI with every advancement in technology…
A few weeks ago, I published a video on how to get max speed from your USB 3 gizmos, which you can find here:
Slow copy speeds with USB 3? No problem!
Right, but if what about lowly USB 2 sticks? They’re far more prevalent than USB 3 sticks, and many of them are veeeery sloooow…
There are a few things to watch out for when buying your next USB stick.
And you don’t even need to be a technical genius!
USB is totally awesome, and USB 3.0+ is even more awesome.
With real-world data transfer rates of 400MB/s or more, copying files to external USB sticks and drives has never been more fun.
Only one problem, and I’ve noticed this A LOT: People are using USB3, but they’re sitting there putting up with relatively slow copy speeds from, say, a USB3 key.
It’s often rather difficult to achieve copy speeds in excess of a measley 40MB/s…
What gives?
Extension cord reels, or rolly cords as I like to call them, are seriously handy.
Nobody likes spending 30 minutes untangling a 50m extension cord.
Trouble is, usually we use them incorrectly!
It turns out you have to read the fine print: You can only use the full capacity of the reel if you fully unwind the rolly cord.
Oops!
I usually see people freak out when they open the door of their circuit breaker panel. No more!
Note that I’m using European breakers and EU-type panel design as my example, so if you’re in North America or certain other countries, you’re not gonna see the same thing. Still, the general principles are the same.
Also keep in mind that there are far more gizmos that you might find in your panel: combined GFCI/circuit breakers, timers, and even a nifty gizmo that turns off circuit B when circuit A is energized.
Having said all that, if you just need a basic intro to breaker panels of all types, this is a good place to start! Then follow up with a book or an internet search for your specific location, and Bob’s your uncle.
You’d think that connecting an LCD screen to your puter would be straightforward. You’d be wrong! It all gets pretty confusing.
There are several types of connectors and cables, and it’s difficult to know which one to use.
Often, you can even use an adapter cable to connect one type of connector to another, like HDMI → DVI.
This video is a summary of the various details of the most popular current cable types.
Cryptocurrencies like Bitcoin and Ethereum are the wave of the future, right?
So why is all the latest news about their value in US dollars? Isn’t that kind of backwards?
Obviously, these new digital currencies have a ways to go…
It doesn’t help that the systems in place are less than stellar, and we’re still seeing hacking resulting in people losing money.
But what about the future of blockchain technologies as a whole? Those are pretty awesome, right?
Well, yes and no. If you cut out the hype, you’ll have a much better idea about where all of this stuff is heading.
There are a few things you need to understand about staying safe and secure online. You need to realize what you’re actually up against.
But don’t fret, because it’s really not a big deal if you always keep in mind how things usually work.
For example, e-mail is never really safe, HTTPS doesn’t really always keep your connection secure, you can be tracked online very easily despite what most people will tell you, and you should always use some kind of anti-virus/malware protection no matter what OS you use.
And remember that the OS you use makes very little difference if you’ve taken some basic precautions… In fact, thinking you’re safe because you use Not Windows is probably a bad idea!
The age old question: How does your electric tea kettle know when to turn off? Is it electronic, or something simpler?
It turns out the key is a bimetallic strip. At a certain, carefully adjusted temperature, the bimetallic strip will bend just enough such that right when the water starts to boil, the bent strip will trigger the mechanism that flips the switch to the OFF position.
It doesn’t matter how much water is in the pot. Once the water is boiling, the temperature in the base will be at a certain point. That temperature point is the trigger threshold for the bimetallic strip. More or less.
That sounds complicated, but watch the video. It’s pretty simple!
Why does AC electrical power come in 3 phases? What the heck is a “phase”, anyway?
In this episode of the EEK! Series, you’ll learn about 3-phase power and its advantages.
In short: fewer wires, more power, and the Earth itself is a conductor.
In addition, 3-phase industrial motors are more efficient and don’t require a starting capacitor since the 3 phases are “rotating” already.
