Our photos are valuable, and we wouldn’t want them to lose quality that we can never get back. In this guide, we’ll show you how to install the optipng tool on Linux, and go over some example commands to help you learn how to use it on your own pictures. You may not always notice the dip in quality, but it’s there. Some of these tools will indeed reduce the size of your images, but they work by recompressing the photo, resulting in a marginal (and sometimes quite noticeable) loss of quality. There are a lot of programs and websites that claim to reduce image file size for you, but be careful. PNG files take up quite a bit more storage space, but we can use the optipng tool on Linux to optimize the compression of our PNG files, resulting in a smaller file size and zero quality loss.Īfter running optipng on a PNG file, the resulting image data is bit-for-bit the exact same as the original, but the file can enjoy a significant reduction in size. Otherwise, opting for the JPG format can yield a better file size at the cost of some quality. It’s a great format to use when you’re concerned about retaining all the quality of your image. WinZip makes it easy to unzip files to ensure you have simplified access to your compressed images.PNG files are losslessly compressed images. You'll have to select multiple files, add to zip, and save them in your desired location. Other formats like TIFF, BMP, SVG, and WebP have their own advantages and limitations, but JPG and PNG are still the most widely accepted image formats. If you're unwilling to compromise the image's quality, it's best to go for PNG image formats with lossless compression. The PNG image format is ideal for graphics and logos with transparent backgrounds. It's best to use JPG pictures on the web where quality is not much of a priority. JPG is excellent for photos and complex images. However, JPG and PNG images are still the most commonly used compressed images. It will always vary on the type of image and its intended use. There is no "one size fits all" answer to this question. Which image format should I use for compression? WinZip offers a variety of popular image compression options, including the most popular choices, JPG and PNG. WinZip is a simple tool for compressing images on both Windows and Mac. If you compress through WinZip, you will reduce the file size while keeping the quality intact, meaning your family photos or images for your website or blog will always look sharp. If you use lossy compression and a compression ratio that drastically reduces the file size, then a change in quality is noticeable. Lossless compression is used when image quality is prioritized over storage space or convenience.įrequently Asked Questions Will compressing my images affect their quality? Lossy compression is best used for general images where fair to poor image quality can be accepted or tolerated. You might see a drastic change if you compress large batches of images.īut compressing small batches will show little to no changes in storage, transmission time, or network bandwidth differences. The compressed image can also be restored to its original form-distortion-free.īut lossless compression reduces only a tiny amount compared to lossy. The reduction in quality is barely perceptible to the human eye. Lossless compression preserves an image's quality and critical data. Lossless compression is the opposite of lossy compression. With the perfect balance, lossy compression can eliminate a large chunk of bytes while maintaining good image quality. Lossy compression doesn't have to mean horrendous image quality, in any case. With lossy compression, the more you reduce the image size, the worse the quality of your image becomes. However, because much data is removed, the image quality is compromised. Lossy compression can considerably lessen an image's file size by eliminating unimportant, repetitive data. Here are the distinctions between the two. losslessĬompressing images involves two methods: lossy and lossless.

A rectangular Sudoku uses rectangular regions of row-column dimension R× C. Unless noted, discussion in this article assumes classic Sudoku, i.e. There are many Sudoku variants, partially characterized by size ( N), and the shape of their regions. same arrangement where all instances of one digit is switched with another digit). 2.55 × 10 25 minimal puzzles that are not pseudo-equivalent (i.e.However, statistical techniques combined with a generator ( 'Unbiased Statistics of a CSP – A Controlled-Bias Generator'), show that there are approximately (with 0.065% relative error): The number of minimal Sudokus (Sudokus in which no clue can be deleted without losing uniqueness of the solution) is not precisely known. 8×8(2×4) Sudoku: The fewest clues is 14.6×6(2×3) Sudoku: The fewest clues is 8.A Sudoku with 24 clues, dihedral symmetry (a 90° rotational symmetry, which also includes a symmetry on both orthogonal axis, 180° rotational symmetry, and diagonal symmetry) is known to exist, but it is not known if this number of clues is minimal for this class of Sudoku. The fewest clues in a Sudoku with two-way diagonal symmetry (a 180° rotational symmetry) is believed to be 18, and in at least one case such a Sudoku also exhibits automorphism. A paper by Gary McGuire, Bastian Tugemann, and Gilles Civario, released on 1 January 2012, explains how it was proved through an exhaustive computer search that the minimum number of clues in any proper Sudoku is 17. Many Sudokus have been found with 17 clues, although finding them is not a trivial task. Ordinary Sudoku A Sudoku with 17 cluesĪ Sudoku with 17 clues and diagonal symmetry Ī Sudoku with 18 clues and orthogonal symmetry Īn automorphic Sudoku with 24 clues and complete geometric symmetry Ī Sudoku with 19 clues and two-way orthogonal symmetry This section discusses the minimum number of givens for proper puzzles. Different minimal Sudokus can have a different number of clues. A minimal Sudoku is a Sudoku from which no clue can be removed leaving it a proper Sudoku. Ordinary Sudokus ( proper puzzles) have a unique solution. No exact results are known for Sudokus larger than the classical 9×9 grid, although there are estimates which are believed to be fairly accurate. Similar results are known for variants and smaller grids. The largest minimal puzzle found so far has 40 clues in the 81 cells. There is a solvable puzzle with at most 21 clues for every solved grid. An ordinary puzzle with a unique solution must have at least 17 clues. There are 26 possible types of symmetry, but they can only be found in about 0.005% of all filled grids. įor classical Sudoku, the number of filled grids is 6,670,903,752,021,072,936,960 ( 6.671 ×10 21), which reduces to 5,472,730,538 essentially different solutions under the validity preserving transformations. Initial analysis was largely focused on enumerating solutions, with results first appearing in 2004. The analysis of Sudoku is generally divided between analyzing the properties of unsolved puzzles (such as the minimum possible number of given clues) and analyzing the properties of solved puzzles. Mathematics can be used to study Sudoku puzzles to answer questions such as "How many filled Sudoku grids are there?", "What is the minimal number of clues in a valid puzzle?" and "In what ways can Sudoku grids be symmetric?" through the use of combinatorics and group theory. For solving and generating algorithms, see Sudoku solving algorithms.Ī 24-clue automorphic Sudoku with translational symmetry This article is about the mathematical analysis of Sudoku puzzles.

Charges you for each state return you file.Frequently prompts you to upgrade or buy more products. He was then essentially the lead in Avengers. Brolin first took on the role for a brief appearance in Guardians of the Galaxy, and returned in the mid-credits scene for Avengers: Age of Ultron. After kicking off his career by playing Brand in 1985's The Goonies, the Oscar-nominated actor has gone on to nab memorable roles in Men in Black III (pictured below), No Country For Old Men, Inherent Vice, Old Boy, and Sicario. Another of Thanos' minions whose appearance in Avengers: Infinity War did not quite showcase the physical beauty of the actor portraying it was Corvus Glaive, whose real-life counterpart Michael. Thanos actor Josh Brolin says he only took on the role because the Titan takes on all of the superheroes in Avengers: Infinity War and Avengers: Endgame. Josh Brolin is a talented actor with a diverse filmography including The Goonies, No Country for Old Men, and Deadpool 2. Marvel's track record with villains hasn't always been on the money (Ultron, we're looking at you), but Infinity War gives Thanos a solid backstory and relatively believable reason for wanting to destroy half of the universe, despite the craziness of the idea.įor those of you wondering why Brolin's voice sounds familiar, it's because you've watched him in countless films over the years. Thanos was originally played by actor and stuntman Damion Poitier in the post-credits scene for The Avengers before being played by Josh Brolin for the rest of his MCU appearances. Fortunately not even that chin can distract from Brolin's fantastic performance, which brings depth, sadness, and even a little bit of empathy to the character. But seriously, guys - what is happening on his chin? Are those skin folds? Individual chin muscles? And why does he bear a startling resemblance to Bruce Willis? While Brolin continues to look better with age, his CGI counterpart cannot say the same. The intergalactic villain, voiced by Josh Brolin - who is also taking on the role of Cable in the Deadpool sequel, interestingly enough - made his first impression in the team-up movie's epic trailers thanks to his pale purple skin and one very questionable goatee.Īvengers: Infinity War marks the most screen time ever for Thanos, who we've only gotten minor glimpses of in the past in 2012's The Avengers and in 2014's Guardians of the Galaxy (he's Gamora and Nebula's dad, remember?). We all knew Thanos was going to be Avengers: Infinity War's big bad, but we weren't expecting his, um, interesting new makeover. It's not as self-contained as the Quest 2 or HP Reverb G2, which can track the room with in-headset cameras. The Index also needs external "lighthouse" boxes similar to the HTC Vive for tracking, meaning you need to set those up in a room first. The Index headset has excellent audio, but its display resolution is no longer as good as competitors'. Not all apps make the most of them, but Valve's hardware is mix-and-match compatible with the HTC Vive, which also is built on the Steam VR platform. Valve's "knuckle" controllers are pressure-sensitive and can track all five fingers, making them almost like gloves. Valve's headset isn't as cutting-edge as it was when it debuted in 2020, but its Steam VR and Vive hardware compatibility, its excellent audio and fancy controllers still make it hardware worth considering. Display: LCD, 2,160 x 2,160 pixels per eye.It lists for $599, but it's often on sale for less. Also, the over-ear speakers are your only audio choice there's no headphone jack. The included controllers, based on Microsoft's VR controller design, feel clunkier than either the Quest 2 controllers or the Valve Index controllers. Built-in camera-based room tracking is easier to set up than the Valve Index's external base stations but is more prone to tracking errors. It's technically a Microsoft Windows mixed reality headset that prefers to launch into Microsoft's native Windows 10 VR ecosystem, but it bridges with Steam VR and works with those games and apps, too. The 2,160x2,160-per-eye resolution and 114-degree field of view are the best at this price range, and the lightweight, comfy headset also has fantastic dropdown speakers designed by Valve. For serious gamers (or VR racing sim fans), it's probably your best choice. If your idea of the best VR headset is to have the best image quality in consumer VR, HP's Reverb G2 wins. Display: OLED, 2,000 x 2,040 pixels per eye.You might want to wait and see what happens, unless you're ready to jump in and trust Sony now. As more games roll out that are optimized for this hardware, however, the PSVR 2 could quickly stand out from the standalone VR pack. Many of the games for this headset are ports of titles you could get on devices like the Quest 2 instead. The PSVR 2 lacks any social metaverse-type software so far and feels more like a headset designed to just launch and play VR games. It could be a landing spot for top PC VR games, but right now it already has some exclusives like Gran Turismo 7, Resident Evil Village and Horizon: Call of the Mountain. However, its HDR OLED display, graphics quality, built-in eye tracking and fantastic advanced controllers - which have the same vibrations and adaptive force-feedback triggers as the PS5 DualSense controllers - give this headset a premium feel that makes its best games perform at a different level. The PSVR 2 is expensive ($550), and needs a PlayStation 5 to even work. Display: LCD, 1,842 x 1,920 pixels per eye.The Quest 2 can also connect with a PC to run more advanced apps from Steam or Meta's own app library, using a single USB-C cable or wirelessly. The Quest 2 reminds me of the Nintendo Switch for its versatility and fun, and it has a growing library of surprisingly effective fitness apps. Meta has also added better parental controls for younger players. Meta also now allows accounts to bypass Facebook logins, although a new Meta account is still required. The base model's 128GB of storage is plenty for storing dozens of games and apps, although keep in mind there's no way to add more storage after purchase. But for those who want an affordable option for families, the Quest 2 remains an excellent pick. For that reason alone, the Quest 3 looks to be worth the extra money. Meta will support the Quest 2 with future software right now, but the Quest 3's more advanced processor will make it more future-proof. The newly announced Quest 3 looks like the better product, however, although it costs more ($500) and we haven't reviewed it yet. It doesn't require a gaming console or PC (although you need to pair it with a phone to set it up). The Quest 2 is still the most affordable and versatile VR headset of the moment. Jira has a useful time tracking function to determine the spent time per project. That allows them to get on with their work without interruption. This can take the hassle of logging off developers’ shoulders by creating a record without requiring manual inputs. And hence calculate far more accurate deadlines.įurthermore, you can absolutely automate time tracking (for example by using apps). Using time tracking, in addition to other statistics (such as story points), you can compare tasks with similar jobs completed in the past. One of the most difficult tasks for project managers is to come up with realistic estimates. The reason why time tracking is important in agile processes is that time tracking allows for triangulation. And while not all Jira users follow agile, plenty of agile dev teams absolutely love Jira. Time tracking is particularly important for agile software development. Jira Time Tracking for Agile Software Development Simply put, time tracking in conjunction with the measurement of results is critical for optimization. But you might be surprised how much tracking time can benefit your business.Īfter all, if you’re not measuring it, then you can’t know if changes make the situation better or not. You may think you know how you spend your time being productive completing your tasks in Jira. If you can’t measure your success, you can’t evaluate it and draw conclusions out of it for the future. “Success has to be measurable” has become an important principle in modern corporate governance.
