Apple is rethinking how components should exist and operate inside a laptop. With M1 chips in new Macs, Apple has a new “Unified Memory Architecture” (UMA) that dramatically speeds up memory performance. Here’s how memory works on Apple Silicon. How Apple Silicon Handles RAM In case you haven’t already heard the news, Apple announced a new slate of Macs in November 2020. The new MacBook Air, MacBook Pro, and Mac Mini models are using an ARM-based processor custom-designed by Apple called the M1 . This change was long expected and is the culmination of Apple’s decade spent designing ARM-based processors for the iPhone and iPad. The M1 is a system on a chip (SoC), which means that there’s not just a CPU inside the processor, but also other key components, including the GPU, I/O controllers, Apple’s Neural Engine for AI tasks, and, most importantly for our purposes, the physical RAM is part of that same package. To be clear, the RAM isn’t on the same Silicon as the fundamental … [Read more...] about How “Unified Memory” Speeds Up Apple’s M1 ARM Macs

Microsoft released Windows CE in November 1996 as a new version of Windows. Designed to run pocket-sized computers, CE brought the user-friendly Windows 95 interface to mobile computing for the first time. Its architecture also formed the basis of Microsoft’s later mobile computing and smartphone products. Here’s why it was needed. A Compact, Portable Version of Windows Windows CE was necessary because full desktop versions of Windows, then tied mostly to the Intel x86 CPU architecture, weren’t practical to run on the pocket-sized devices of the time. As a result, Windows CE represented an entirely different platform from its desktop OS cousins. It couldn’t run programs designed for Windows 95 or Windows NT. Windows CE’s design emphasized low power usage, compatibility with flash memory storage, and relatively low memory requirements. It also retained a user-friendly graphical user interface (GUI) similar to Windows 95 , complete with the Start menu, and even a built-in … [Read more...] about What Was Windows CE, and Why Did People Use It?

We’ve covered why “Do Not Track” isn’t a silver bullet that prevents you from being tracked . However, if you don’t like being tracked and want to express that preference to websites, you can enable “Do Not Track” in every browser. To Google’s credit, future versions of Chrome explain exactly what Do Not Track does when you enable it. Remember that, by enabling Do Not Track, you’re just expressing a preference. Websites may or may not obey your preference. Mozilla Firefox In Firefox, click the Firefox menu button and select Options. Click over to the Privacy tab and enable the Tell websites I do not want to be tracked check box. Firefox will send the DNT: 1 HTTP header whenever you connect to a website. Google Chrome When this article was written, Google was on the verge of adding Do Not Track to the stable version of Chrome. To enable Do Not Track in Chrome 23 and later (the unstable versions of Chrome, when this article was written), click Chrome’s menu … [Read more...] about How To Enable Do Not Track In Every Web Browser

You can’t believe everything you read—or see. Social media is rife with manipulated or “Photoshopped” images. Here are some telltale signs you’re looking at an altered image. Airbrushing Is Easy to Spot Have you ever seen an image that just doesn’t look right? Trusting your gut might not be the most scientific approach, but you’re probably better at spotting a fake than you realize. If you see an image that sounds alarm bells, you might want to look a bit closer. You’ll probably spot some telltale signs that it’s been manipulated. Airbrushed images often fall into “ uncanny valley ” territory. Even if you have perfect skin, most light sources cast small shadows on fine wrinkles, pores, and other slight imperfections. When these imperfections are digitally removed, so is the appearance of natural lighting. Professional retouchers often strike a balance between perfection and realism, but amateurs and mobile apps rarely do. Apps, in particular, depend on existing skin tones … [Read more...] about How to Tell If an Image Has Been Manipulated or Photoshopped
