There's talk that Apple has bought a MicroLED display company called MicroView. Some think that indicates they're going to make a TV, but MicroView tends to mean that they are going to bring those screens to mobile phones or even the Apple Watch. The Apple Watch displays 320 dpi, but Scott has heard of breakthroughs to 1600 dpi. If you get to the point that you can't see the dot, then it becomes pointless to get any sharper. Leo says that the reason to get DPI that high is for Virtual Reality, and that really may be what Apple is up to.

How can I email files securely?

Email

Episode 1471

Fred from Fort Worth, TX

Leo says that Fred is right to be concerned about the security of sending emails because the contents of the messages can be read along the way. If the email is going from one Gmail address to another, however, it would be secure. Ultimately, though, Leo doesn't recommend sending attachments at all. Opening attachments is how most people end up getting infected, and it doesn't just affect that person either. It will spread to all of that person's contacts, affecting their family, business, and the internet as a whole.

Get More Out of Live Photos on iPhone

If you have an iPhone, you may already be familiar with the Live Photo feature that it has. When Live Photos are enabled, whenever you take a picture, the iPhone will also capture a few seconds before and after the shot is taken. This gives the photo some motion, almost like a very short video clip. But you may not know that it can actually go beyond just that basic functionality. After you take a photo of something that moves, go to edit the photo and swipe up. This will reveal a few different effects that you can apply.

Tech companies announced quarterly earnings last week, and everything was up. Alphabet's revenue was up 24%, but because of the new tax law, it actually lost money.

Ebay lost money because it had to pay $3.1 billion, and Lenovo lost money because it had to pay $400 million in taxes.

2018 brought about the news that every processor built in the last ten years have a flaw in them that could give hackers access to sensitive data. Initially believed to affect just Intel processors, the latest is that this affects every single processor made, regardless of platform.

The flaws utilizes a technique called "processor speculation," which enables the processor to speculate what the user will do next in order to accelerate performance. But the feature also gives hackers access to sensitive L2 cache data like passwords. It's especially true for networks.

Apple has released the iMac Pro, which it announced earlier this year. This computer starts at $4,999, and it's not hard at all to configure it up to $10,000. This is for professionals who are using it for business, like 3D design, photography, and video editing. Even if you did decide to spend the money on that, it still wouldn't be the fastest computer out there. This isn't even the fastest Mac. It all depends on what you do. It's using the Intel Xeon chip, which has 8, 10, 12, and 16 cores. But, when you get these multiprocessor Xeon chips, they run at a slower clock speed per process.
