What Is a CHN File? A file with the CHN file extension is an Ethnograph Data file that stores information necessary for running analysis in Qualis Research’s Ethnograph software. This software is used by scientists, researchers, engineers, medical professionals, and other professions where data needs to be analyzed. Other CHN might instead be associated with Encom’s Em Vision software as some sort of 3D model, or possibly used with Marimba Network’s Castanet tuner software....

GameClub launched late last year, bringing a slew of mobile classics back into the game for just $4.99 per month. Now the service is looking to expand its options even more by offering subscribers access to PC ports of certain indie hits. Chook and Sosig: Walk the Plank is the first to hit the GameClub library. “There [have] been existing point and click adventure games that were released on the app store and they work pretty decent with fairly minor modifications....

There are actually many other reasons, especially for larger companies that use messaging systems, but for the majority of users, creating a Jabber server comes down to the security of knowing that your home or small business iChat messages aren’t accessible to outside eyes....

What Is a CV File? A CV file has a CV file extension and might be related to either Corel Versions, as an archive file type, or Microsoft CodeView, enabling a multiscreen application that supports source code editing and debugging. Some CV files might instead be Cvip files, but we don’t have any information on how it’s used. How to Open a CV File CV files that are Versions files are opened using Corel Versions, an add-on program that existed only with Corel WordPerfect 8 and 9....

The k-means algorithm is one of the simplest clustering techniques and it is commonly used in medical imaging, biometrics, and related fields. The advantage of k-means clustering is that it tells about your data (using its unsupervised form) rather than you having to instruct the algorithm about the data at the start (using the supervised form of the algorithm). It is sometimes referred to as Lloyd’s Algorithm, particularly in computer science circles because the standard algorithm was first proposed by Stuart Lloyd in 1957....

Defining Old Style, Lining, Proportional, and Tabular Figures Old Style Figures (OsF) Also called non-lining figures, these Arabic numerals are not all the same height and some extend above and others below the baseline (like the ascenders and descenders on some lowercase letters). Lining Figures (LF) A modern style of numerals also known as short ranging figures or regular numerals, lining figures are all the same height and all figures sit on the baseline....

LED Definition LED stands for Light-Emitting Diode, an electronic device made of two types of semiconductor material. Similar in concept to the semiconductor material used in computer components (such as RAM, processors, and transistors), diodes are devices that allow the flow of electricity to occur in only one direction. An LED does the same thing. It blocks the flow of electricity in one direction while letting it move freely in the other....

Your local Chevron station would become a ChEVron (see what I did there) charging location. Electric vehicles (EVs) would be lighter, cheaper, and be back on the road as quickly as a gas-powered car. The source of all this magic is solid-state batteries, and they’re going to change the world. Except, don’t hold your breath waiting for one in a car anytime soon. Every few months, a company, sometimes a major automaker, informs the world that solid-state batteries are just around the corner....

However, third-party websites host the games and offer these games as free downloads to users of Windows computers. These sites include AllGamesAtoZ, BestOld Games, and CNET. Original Grand Theft Auto (1997) The original Grand Theft Auto game was released in 1997 by a small studio named DMA Design, which would later become Rockstar Games. The development company and the Grand Theft Auto series of games expanded rapidly in the years that followed, with the release of more than a dozen Grand Theft Auto titles across various platforms, along with other award-winning and best-selling games, such as Max Payne and L....

High-Speed Stepper Motor Factors Several factors become design and implementation challenges when you drive stepper motors at high speeds. Like many components, the real-world behavior of stepper motors is not ideal and far from theory. Stepper motors’ max speed varies by manufacturer, model, and the inductance of the motor, with speeds of 1000 RPM to 3000 RPM usually attainable. Inertia Any moving object has inertia, which resists changes to the acceleration of an object....

In a blog post, Alphabet’s drone-delivery service, Wing, announced that it has commenced operations in the Dallas-Fort Worth Metroplex, hoping to serve tens of thousands of suburban homes in the area. Drone delivery experts, however, aren’t really excited about this particular use case for the aerial vehicles, especially in urban areas. “I’m skeptical about food and parcel drone deliveries, from a business perspective,” Stephen Sutton, CEO of drone service provider, Flyby Guys, told Lifewire over email....

How to Use the Track Changes Feature When Track Changes is active, all changes made to a document are automatically marked in a variety of colors. Each color is assigned to a different collaborator on the document. This makes deletions, additions, edits, and moves readily visible and collaborators identifiable....

How POP Works Incoming email messages are stored at a POP server until you log in (with an email client) and downloads the messages to your computer. The POP standard doesn’t include the means to send messages. Simple Mail Transfer Protocol (SMTP) is used to send emails. How POP Compares to IMAP POP and Internet Message Access Protocol (IMAP) are similar in that both are used for email retrieval. However, POP is older and defines only simple commands for email retrieval....

Now you can get VR on your iPhone. If you’ve seen people using virtual reality, it’s probably with handheld or head-mounted viewers like the Samsung Gear VR (though the HTC Vive is better used in a full room). And if you’re an iPhone user, you may have wanted to get in on the action and try virtual reality yourself. Right now, virtual reality is a bit more robust for Android, but there are still a number of ways to use it on an iPhone....

The ISNUMBER function’s job is to determine if the data in a certain cell is a number or not. If the data is a number or is a formula that returns a number as output, a value of TRUE is returned by the function — the example in row 1 in the image above.If the data is not a number, or the cell is empty, a FALSE value is returned — the example in rows 2 in the image above....

When it comes to audio quality, you’ll want a shower speaker with loud, crisp audio and booming bass you can hear over the sound of the water running. A long battery life is an added bonus, giving you several shower sessions before needing to worry about recharging. Some more advanced speakers come with options to sync one or more together for a full stereo setup, while others are exceptionally portable and durable, lending them to outdoor use and not just the shower....

Luckily, switching to a wireless mouse doesn’t mean sacrificing precision or having to deal with frequent battery changes. The mice we’ve reviewed here all have fantastic specs, such as high counts per inch (CPI) and inches per second (IPS) ratings, to perform just as well as their wired brethren. When shopping for the best wireless mouse, you’ll want to look for features such as battery life, compatibility with multiple devices, ergonomics, and portability....

Choose What You Want to Export It may seem obvious that you need to choose what you want to export, but it is a question you should ask as Inkscape allows you to export all the drawn elements in a document, just the area of the page, only selected elements, or even a custom area of the document. If you want to export everything within the document or the page only, you can proceed, but if you don’t want to export everything, choose the Select Tool in the Tools palette on the left side of the screen....

The main draw of Live Audio Rooms is providing Facebook groups with a new way to engage with their members. Hosts can create an audio room with up to 50 speakers, while a limitless number of listeners can attend and ask questions in the chat, request audio speaking access, etc. There’s potential here, from a business and community standpoint. “Because Facebook Live Audio Rooms take elements of a live Zoom meeting and YouTube live (minus the faces), but adds collaboration and more control via permissions to the host who can listen and create their own audio rooms, there is a breadth of potential here,” said Emily Hale, social media analyst at Merchant Maverick, in an email interview with Lifewire....
