What Is a PPSX File? A file with the PPSX file extension is a Microsoft PowerPoint Slide Show file. It serves as an update to PPS, a format used for the same purpose in MS Office versions 2007 and earlier. These files open directly to the presentation because they’re meant to be used just for presenting the slideshow. PowerPoint files that open directly into the editing mode are saved with the PPTX extension....

Adobe fixed its photo editing and storage app immediately, but the lost images remain gone unless individual users had their own personal backup. Your photos contain the memories and history of your family, friends, and your whole life. Losing them is one of the biggest data-loss nightmares for most people. “After the automatic update to Lightroom mobile 5.4 on my iPad Pro (active subscription), my whole library is lost,” wrote Lightroom user Christoph Willerscheidt in the Photoshop Forum....

What Is a PSF File? A file with the PSF file extension is most likely an Adobe Photoshop Proof Settings file. These kinds of files store specific color preferences so that you can see how an image will look before you print it. A PhotoStudio file is an image format that uses this same file extension. They can contain text, layers, and shapes. Other programs might use the PSDF file extension, too, like as a GPS Prediction Support file, AutoCAD PostScript Patterns file, Portable Sound file, PID Script file, or an HP-UX Product Specification file....

The two main issues are efficiency and undesired interference from the additional harmonics present in a modified sine wave. That means that a pure sine wave inverter is good at two things: efficiently powering devices that use the alternating current input without rectifying it first and powering devices like radios that can suffer from interference. Do You Need a Pure Sine Wave Inverter? Some useful questions to ask yourself to determine if you need a pure sine wave inverter include:...

It’s getting rereleased now to build up hype for its sequel, simply called Dark Alliance, which is set to release on PC and consoles early next month. Playing it in 2021, I’d forgotten just how foundational it is. It’s very much a diet Diablo, an attempt to port the smash-and-grab gameplay of a good dungeon crawler into a console-friendly, Dungeons & Dragons-themed format. The original Dark Alliance does end up feeling a little bare-bones now, but it also puts almost zero nonsense between you and the action....

Dell has announced a new design concept for a laptop that has a long life and is easy to repair. Experts say repairable electronics could take less of a toll on the planet by reducing waste. “It feels like our society has sadly accepted that many electronics are disposable, as they can’t be repaired,” Amanda LaGrange, an electronics recycling advocate and CEO of Tech Dump, told Lifewire in an email interview....

According to ETNews, the two Korean companies showed off their new tech at the Global Tech Korea 2021 event. In Samsung’s demo, different display sections rose and fell to mimic a lava bubble forming and then dissipating on its own. However, the stretchable screen does make the video lava seem more realistic as it flows. The earliest concepts were shown back in 2017, albeit with a smaller 9.1-inch display. According to Changhee Lee, the executive vice president of Samsung Display, these displays could only be stretched out by a small amount but have “improved significantly” recently....

While rumors about the Galaxy S21 FE have been swirling for some time, this is the first time Samsung has officially detailed the device in any capacity. Previously the company has released FE (or Fan Edition) versions of its primary flagship devices as cheaper variants for users to purchase. The S21 FE will feature the same 5nm 64-bit Octa-Core processor as the original Galaxy S21. Samsung says the processor will deliver fast but quality graphics on an ultra-crisp 6....

A new update gives the Xperia PRO and Xperia PRO-I additional options for when they’re being used as an external monitor—typically paired with one of Sony’s Alpha cameras. Using the Xperia PRO as an extra monitor for your camera has been possible since its release, but this expansion aims to add more direct control through the smartphone. Both the Xperia PRO and Xperia PRO-I will now be able to use the Waveform function when being used as a monitor to better control exposure and RGB balance....

The WF-1000XM4 builds off of the noise cancellation technology used in previous Sony products by adding two noise sensing microphones in each earbud—one feed-forward, one feed-backward. These microphones will analyze ambient noise and work in conjunction with a newly designed 6mm driver unit to generate a noise-canceling signal with a 20% magnet volume increase. There is also an Automatic Wind Noise Reduction mode for use on windy days. In addition to noise cancellation, the WF-1000XM4 supports High-Resolution Audio Wireless with a 900 kbps maximum transfer rate, as well as 360 Reality Audio, when paired with an applicable smartphone....

You know how, when you need customer service, the lack of phone lines and physical offices means you’re funneled toward using a chatbot? Well, how about using your own chatbot to chat back and even up the score? That’s the promise of the new GPTChat-based bot from the defender of the masses, DoNotPay, which can negotiate bills and save you a ton of money. “Chatbots don’t get angry, and they don’t get frustrated....

If you’ve ever wanted it to be just a bit simpler to keep track of new content from the accounts you follow on Spotify, your not-quite wish is being granted. Spotify has announced its new What’s New feed, which lists new releases from the artists and shows you follow in one spot. Seeing as the service claims over 50,000 hours worth of content added every day, a method of sifting through it all is pretty much essential....

Valve just announced that the Steam Deck launch is delayed for two months from December 2021 to February 2022. The PC gaming giant blamed the delay on global supply chain issues, according to a company blog post and emails sent out to people who preordered the console. “We did our best to work around the global supply chain issues, but due to material shortages, components aren’t reaching our manufacturing facilities in time for us to meet our initial launch dates,” the company wrote on Wednesday....

In addition to featuring some genuinely enjoyable single-player offline story campaigns that will keep players of all ages busy for days, each Pokemon game also supports online multiplayer in the form of Pokemon trading and battles.

Let’s start with the fact that many smartphones are ditching the headphone jack, meaning your expensive corded headphones are useless. You might be a runner or someone who’s really keen on portability. MP3 players are often much smaller than smartphones. You might prefer a more simplistic interface or you might want to conserve your phone’s battery or storage space. Whatever the reason, a dedicated audio player (or DAP) might just be right for you, and we’ve got some of our favorites down below....

What Are Cleaners for Android Phones? When you delete an app, residual data remains stored on your device. Ads, notifications, and your browser history all leave traces of data in the system cache, which can slow your device down over time. Cleaning apps get rid of these lingering files to free up storage space and make your device run faster. Many cleaners perform additional optimizations, and some even offer antivirus protection....
