![]() How to set up s oftware RAID 1 step by step? It is a trend, and you can flexibly set up software RAID via Windows Disk Manager. Usually, Windows Professional Edition and Windows Server Edition systems can support it. It is the best choice for common personal users and server users. Software RAID is well supported by the operating system, which is implemented by OS kernel module, and no required extraordinary hardware. This means it takes a high cost to set up hardware RAID. Hardware RAID can be implemented by requiring high hardware requirements, in the form of special disk controllers, but also needs computer motherboard support. Usually, RAID 1 and RAID 5 are widely used to solve the risk problem of server data storage. How to protect server data? Many users choose to use RAID to deal with the risk of hardware failures. In the IT world, hardware failure does not occur often, but in the event, the running server may lose large amounts of important data. There are a variety of different types and implementations of RAID, each with its own advantages and disadvantages. HDD boot order will have to be probably modified also in BIOS.RAID is a technology that allows a volume (partition) uses together with the space on the multiple disks, in this way, disk's utilization and system performance can be improved.

![]() Shortly after the game was invented, some of its inventors founders and their friends brought pickleball to Hawaii, where the game became known as pukaball. They did, however, discover a third possibility: Bill Bell claimed that he had named the game because he enjoyed hitting the ball in a way that would put his opponent in a pickle. Jennifer Lucore and Beverly Youngren, authors of the book, History of Pickleball: More than 50 Years of Fun!, say that they could not conclusively determine whether the game was named for the dog or the dog was named for the game. Representatives of USA Pickleball claim that research on their part has confirmed that the dog Pickles was born after the game had already been named. They said the confusion arose when a reporter interviewing the Pritchards in the early 1970s decided it would be easier for readers to relate to the dog rather than a pickle boat. The Pritchards stated that the dog came along after the game had already been named, and it was the dog that was named for the game of pickleball. Pritchard and two of his friends, Barney McCallum and Bill Bell, are credited with devising the game and establishing the rules.Īccording to Joan Pritchard, Joel Pritchard's wife, "The name of the game became Pickle Ball after I said it reminded me of the pickle boat in crew where oarsmen were chosen from the leftovers of other boats." Other sources state that the name "pickleball" was derived from the name of the Pritchards' family dog, Pickles. The game was created in 1965 on Bainbridge Island, Washington, at the summer home of Joel Pritchard, who later served in the United States Congress and as Washington's lieutenant governor. Pickleball is also growing in popularity outside the United States: there are several other national and international competitions. Open Tournament, along with two professional tours and one professional league. There are now thousands of pickleball tournaments throughout the United States, including the US National Championships and the U.S. The growing popularity of the sport has been attributed to its short learning curve, its appeal to a wide range of ages and fitness levels, and its low startup costs. In 2021, 20, the sport was named the fastest-growing sport in the United States by the Sports and Fitness Industry Association, and by 2023 it was estimated to have over 4.8 million players. To minimize any advantage the serving or receiving side might have at the beginning of the game, the ball must be allowed to bounce once on each side of the net before players are permitted to volley the ball (that is, to hit the ball before it has bounced on their side of the net).īetween 19, pickleball became a popular sport in the Pacific Northwest region of the United States, and also began to grow in popularity elsewhere. The minimal amount of bounce, the non-volley zones, and underhand serve combine to give the game a dynamic pace and a choice of hitting strategies, ranging from soft dink shots that stay within the two non-volley zones to powerful drive shots and overhead smash shots. The hard plastic ball used in pickleball produces significantly less bounce than softer, flexible balls such as tennis balls. All serves are made with an underhand stroke. The official rules specify side-out scoring, meaning that only the player or team serving can score a point. There are two 7-foot areas (2.1 m) on either side of the net, known as the non-volley zones, where the ball may be hit with the paddle only after it has bounced. The rules, and the position of lines on the court, are specific to pickleball. The court is the size of a doubles badminton court (less than a third the size of a tennis court), and the paddle is larger than the one used in table tennis. The pickleball court and the manner of play resemble tennis in some respects and ping-pong (table tennis) in others. In 2022, pickleball was named the official state sport of Washington. Pickleball was invented in 1965 as a children's backyard game in the United States, on Bainbridge Island in Washington state. Opponents on either side of the net hit the ball back and forth until one side commits a rule infraction. Pickleball is an indoor or outdoor racket/paddle sport in which two players (singles), or four players (doubles), hit a perforated hollow plastic ball over a 36-inch-high (0.91 m) net using solid-faced paddles.

To use the pg_trm module, you need to enable the extension and create the index passing in the default gin_trgm_ops: The pg_trgm module supports GIST or GIN indexes and as of Postgres version 9.1 these indexes support LIKE/ ILIKE queries.

I’ve got a very simple users database table populated with 1 million rows. I'm pretty sure Postgres has already solved most of my problems, I just haven't made it to that part of the documentation yet. Indexing columns for LIKE queries was perfect example of this. Whenever I need something from it, it’s usually already there, I just cant always find how to do it. The more I work with PostgreSQL the more it impresses me. Quite often, structuring and indexing the database correctly can keep your queries nice and fast. However, we don’t always need such substantial dependencies in an app. Tools like Elastic Search or Solr are great at providing quick intelligent searches on large datasets. Users expect search to fast and to be accurate. Search is often an integral part of any web app, but it’s also one of the parts that can cause performance problems. It took me a while to figure out the right way to index columns for LIKE lookups, especially for indexing compound columns. Recently I wanted to add basic text search to an application I as working on. ![]() The only thing you can work with is the name of the brand or the product. This type of logo will not contain any symbols, emblems, or graphic patterns. A text logo, for instance, can be a logo that includes the name of a company, brand, institution, or organization. What is a Text Logo?Ī text logo (also called a wordmark or logotype) is any logo that contains only text design elements. In the end, we will also explore other ways to make a text logo in a few simple steps using Vectornator. We will also explore the importance of tweaking the text logos you make and play around with sizing, alignment, typeface, color, and more until you achieve a logo you can be proud of. Whether you want to create vintage type logos, 3D type logos, or cartoon-style logos, we hope the following guide will come in handy and be a source of inspiration.Īre you looking to create a custom text logo in Illustrator? In this article, you will learn how to manipulate letterforms, how to combine several letters and words, how to create unique shapes, and how to use negative space to your advantage with Adobe Illustrator. To make it easier for you, we'll focus on creating a minimalist text logo that's easy to create with this guide. You can use a minimalist logo on a business card and it will still be visible. One of the reasons why minimalist design and minimalist logos have become quite popular in the past decade is thanks to their simplicity and scalability. The spaces between the letters (kerning) and any overlaps will also be essential.Ĭhoosing a legible, simple, yet stylish type can make your text logo more memorable. You will have to transmit the feel and the identity of the brand with the way you present each letter and each word. Typography plays a key role when designing a logo featuring a company's full name or initials. Since there are thousands of ways you can draw each letter of the alphabet, and an equal number of ways you can combine them, there are so many options when it comes to making a logo. But don't fret! Today you'll learn to make a text logo in Illustrator by following these step-by-step instructions.Ĭombining shapes, letters, and negative space can do wonders when creating a custom text logo. Making a text logo is more complex than it sounds. In watching video of him, it sure looks like he’s become increasingly prone to letting the transition from his toe tap to his real stride carry him away from home plate, opening him up too much. To begin his swing, though, Rosario uses a toe tap, then strides forward and opens his front hip. That’s a little surprising, initially, because he has that familiar, closed stance, with his front foot near the inner line of the batter's box. Rosario hasn’t been hit by a pitch since July 29, 2016. Rosario hit those pitches harder than ever, on average, in 2019, but elevated it less, and the result was considerably less production-and more groundouts into the shift. A would-be left-handed slugger, especially one without the discipline to draw walks consistently, needs to do more damage than that on the inside pitch. Worse news: on pitches on the inner part of the plate (and just off it), Rosario has gotten steadily less productive over the last three years. ![]() He’s becoming more one-dimensional, and given his ability to consistently make contact on such a wide array of pitches, that seems like the kind of concession he could avoid making if he rearranged his approach. According to Baseball Savant, he pulled just 32.1 percent of his batted balls in 2017, but that number rose to 40.6 percent in 2018, and in 2019, it soared all the way to 44.4 percent. Rosario hasn’t always been such a pull-conscious hitter. Thus, the real question isn’t whether Rosario can conquer the shift (he actually hit better against it than against non-shifted defenses last year), but whether he can change the thing that led to all those shifts in the first place: his pull rate. That’s been true since long before the shift became widely used, though. It’s very hard to be a shift-prone (pull-happy) left-handed hitter and succeed, without being patient at the plate. Certainly, their patience correlates strongly with their success. These are, by and large, patient hitters. It’s no surprise that all of those are left-handed batters (save Santana, who is a slow-footed switch hitter), but interestingly, most of the group is similar in other ways, especially in terms of approach. Freddie Freeman, Anthony Rizzo, Cody Bellinger, Kyle Schwarber, Brandon Belt, Kole Calhoun, and Charlie Blackmon were those seven hitters, and the two immediately behind Rosario were Carlos Santana and Bryce Harper. Last year, only seven batters saw more shifts than did Rosario, according to Baseball Info Solutions. To do so, he’s going to have to solve the shift. ![]() The main issue, in forecasting Rosario’s near and medium-term future, is whether he can get himself going well more frequently, and going badly less often. ![]() ![]() Still, the primary problem isn’t how Rosario looks when going badly, just as evaluating him can’t be boiled down to how he looks (usually, great) when going well. An exceptionally aggressive hitter at the best of times, he seems to swipe hopelessly at the ball when going badly, missing some pitches badly and weakly mis-hitting others. That feels dauntingly plausible, because when one watches Rosario at the plate during one of his slumps, it’s little stretch to say that he appears to have forgotten how to hit. Visit Rosario’s Baseball Reference page, and the news is grim: his (real) brutal spring training has carried over into his (non-real) regular season, and he’s no longer a Twins regular. One key question underpins any effort to tell whether he can sustain more consistent success in the future: Can Rosario go the other way?Įverywhere one turns (including here at Twins Daily!), there’s a simulation of the 2020 season happening, in one form or another and through one vendor or another. Yet, the dichotomy in his half-season splits speaks to the impact potential he still has. That, more than his somewhat old-fashioned approach or his lack of fielding or baserunning value, is why he’s broadly seen more as a trade candidate than as a likely mainstay for the Twins. In each of the last three seasons, Eddie Rosario has hit like a star for about half a year, then been average (or considerably worse) for about as long. ![]() The receipt must show the student’s name date of purchase purchase price name, address and phone number of the store where the computer was purchased and a full description of the computer and software purchased.

The Automatic1111 Stable Diffusion UI is a popular web-based open source user interface for using the tool on one's own computer including, continuously integrated, new features (such as "Inpainting" or "Textual Inversion"). This enabled the development of further applications and extensions, such as plugins for Krita, Photoshop, Blender, and GIMP. On 22 August 2022, Stable Diffusion was released, making the technology much more accessible and free to use on personal hardware as well as extendable by third-parties (i.e. The input can also include images and keywords and configurable parameters, such as artistic style, which is often used via keyphrases like "in the style of " in the prompt and/or selection of a broad aesthetic/art style. They include OpenAI's DALL-E, which released a series of images in January 2021, Google Brain's Imagen and Parti which was announced in May 2022, Microsoft's NUWA-Infinity, and Dream by Wombo. Several programs use text-to-image models to generate a variety of images based on various text prompts. The website Artbreeder, launched in 2018, uses the models StyleGAN and BigGAN to allow users to generate and modify images such as faces, landscapes, and paintings. After DeepDream's release, several companies released apps that transform photos into art-like images with the style of well-known sets of paintings. ĭeepDream, released by Google in 2015, uses a convolutional neural network to find and enhance patterns in images via algorithmic pareidolia, thus creating deliberately over-processed images. More recent models use Vector Quantized Generative Adversarial Network and Contrastive Language–Image Pre-training (VQGAN+CLIP). This system uses a "generator" to create new images and a "discriminator" to decide which created images are considered successful. Generative adversarial networks (GANs) were designed in 2014. Įxample of image made with VQGAN+CLIP (NightCafe Studio) Cohen designed AARON to paint using special brushes and dyes that were chosen by the program itself without mediation from Cohen. Throughout the years, he also began to develop a way for AARON to also paint. Cohen would later finish the drawings by painting them. In its primitive form, AARON created simple black and white drawings. Cohen developed AARON with the goal of being able to code the act of drawing. AARON is the most notable example of AI art in the era of GOFAI programming because of its use of a symbolic rule-based approach to generate technical images. One of the first significant AI art systems is AARON, developed by Harold Cohen beginning in the late 1960s at the University of California at San Diego. ![]() Many mechanisms for creating AI art have been developed, including procedural "rule-based" generation of images using mathematical patterns, algorithms which simulate brush strokes and other painted effects, and artificial intelligence or deep learning algorithms, such as generative adversarial networks (GANs) and transformers. Since its founding, researchers in the field of artificial intelligence have raised philosophical arguments about the nature of the human mind and the ethical consequences of creating artificial beings endowed with human-like intelligence these issues have previously been explored by myth, fiction and philosophy since antiquity. Early history Īrtificial intelligence was founded as an academic discipline in 1956, and in the decades since has experienced several waves of optimism. While both AI art and digital art involve the use of technology, AI art is characterized by its use of generative algorithms and deep learning techniques that can autonomously produce art without direct input from human artists. It is sometimes confused with digital art.
