Are you taking proper care of the battery in your laptop? While chips are getting more efficient and battery life is increasing, avoiding a few mistakes can help extend your laptop battery health in the long term.
With that in mind, the lithium-ion battery inside your laptop will last longer if it does not hold a high voltage level for prolonged periods. If we’re talking about battery health, the life of your battery can be prolonged by not keeping it at 100% constantly. This means using your battery by unplugging it during the day, rather than keeping it plugged in.
SEOUL, June 17 (Reuters) – For Jung Ki-young, a South Korean software engineer, Microsoft Corp’s (MSFT.O) decision to retire its Internet Explorer web browser marked the end of a quarter-century love-hate relationship with the technology.
To commemorate its demise, he spent a month and 430,000 won ($330) designing and ordering a headstone with Explorer’s “e” logo and the English epitaph: “He was a good tool to download other browsers.”
After the memorial went on show at a cafe run by his brother in the southern city of Gyeongju, a photo of the tombstone went viral.
Microsoft scaled down support for the once omnipresent Internet Explorer on Wednesday after a 27-year run, to focus on its faster browser, Microsoft Edge.
Jung said the memorial showed his mixed feelings for the older software, which had played such a big part in his working life.
“Unlimited” is a big word in the mobile world. Everyone wants a data plan with no limitations. That’s why carriers love to use the word, but “Unlimited” rarely means truly unlimited. There are a few reasons for that.
There was a time when unlimited data planswere truly unlimited. You paid a certain amount every month and you could use as much data as you wanted. However, as more of the world has adopted smartphones, these plans have gone away.
The biggest catch in most “unlimited” data plans is speed limits. It’s common practice for unlimited plans to only allow access to high-speed data for a set amount, such as 25GB. After you use that much data, your speed gets throttled down.
If you’ve ever shopped for home networking, there is an excellent chance you have heard about Ethernet cables. But what are they for, why would you want to use them, and how do they differ?
A Reliable Network Connection
An Ethernet cable is a cable that you connect between your computer, TV, gaming console, or another device and a router, modem, or network switch. It gives your device access to a local network or the internet. Although Wi-Fi has become a very common way of connecting to the internet, an Ethernet cable can provide a faster and more stable internet connection than wireless currently can.
Ethernet cables typically use RJ-45 connectors on both ends and can be as long as 300 feet. Additionally, there are no upstream or downstream ports in an Ethernet cable, so you can plug whichever end you want into a router or your computer.
If you’re trying to connect to a Wi-Fi access point and you see “FBI Surveillance Van” in your SSID list, should you be worried? Is there an FBI van outside your door? We’ll get to the bottom of this surprisingly common situation.
It’s a Practical Joke
If you see “FBI Surveillance Van,” “FBI Van,” “NSA Van,” or “Police Surveillance Van” on your list of Wi-Fi routers or access points, don’t worry: It’s just someone nearby playinga practical joke. This joke originated in the early days of Wi-Fi—in the 2000s—because it ties into a common fear that someone might be lurking nearby and watching you. Also, in the early days of Wi-Fi, some people used scary-sounding SSID names as a deterrent to keep people from connecting to their open(not password protected) Wi-Fi access points.
Phones with Touch ID look different than iPhones with Face ID, and it can also change how you use certain features on your device. Here’s how to spot a phone with Touch ID—and a list of models that support the feature.
What Is Touch ID?
Touch ID is a biometric authentication feature that recognizes your fingerprint to verify your identity. To use it, you gently place your finger on the Touch ID sensor build into the home button. It comes in handy because you don’t need to type in your PIN number or passwords as often when purchasing apps, logging into accounts, or unlocking your iPhone.
In physics, a “weber”, named after the German physicist Wilhelm Eduard Weber, is the SI unit of magnetic flux. A weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.
f you’re buying a new amplifier or speakers, paying attention to the impedance of each is important. Why? Because a mismatch can seriously damage either of them. Let’s take a look at how to avoid that.
The Elements of Electricity
It’s tough to talk about ohms without mentioning the other elements of electricity. So, before we dive deeper into ohms, let’s take a look at all the elements of an electrical signal as it applies to audio.
Faraday bags use the same principles as a Faraday cage to prevent wireless signals from leaving or reaching your devices. So what are the reasons to use one, and how is it different from turning the device off or using airplane mode?
How Faraday Bags Work
Faraday bags are essentially portable, flexible Faraday cages. A Faraday cage, named after scientist Michael Faraday, blocks electromagnetic waves from reaching anything inside it.
These cages work by surrounding an object with a conductive metal mesh. When an electromagnetic field encounters the cage, it’s conducted around the objects inside. If you were struck by a bolt of lightning while inside a Faraday cage, you’d be completely unharmed as the energy is diverted around you. Ideally, the cage should be made of continuous metal, but that’s often too expensive or impractical. A mesh works just as well, as long as the holes in the mesh are sufficiently smaller than the wavelength of the signals you want to block.
Getting back to Faraday bags, these are made of a conductive metallic fabric that blocks signals from reaching whatever is inside. You can buy these bags just about anywhere these days, so are they worth your time and money?
Why Use a Faraday Bag?
Consider that your smartphone probably doesn’t have a removable battery and that your Wi-Fi, Bluetooth, and other internal radios are operated by a software switch—not a physical kill-switch. In other words, you have no way of knowing that your device is really not sending and receiving data when you put it in airplane mode or toggle Wi-Fi off.
That’s one reason that Faraday bags are useful. When you want to make sure your devices aren’t shaking hands with Wi-Fi hotspots, cellular towers, RFID readers, and Bluetooth beacons, you can use a bag to hide them. If you want to temporarily go incognito, using a Faraday bag is better than
