For more help on what to remove, read How to Rid a PC of Crapware.įrom the Start menu, type Disk Cleanup to open the trusty utility that's been part of Windows for several generations of the OS. While you're in the Programs and Features section of Control, you can also click Turn Windows Features On or Off and scan the list to see if there's anything you don't use. One reason removing apps helps performance is that many programs load processes at boot time and take up valuable RAM and CPU cycles. In either, you can sort them by size, date installed, or name, or search for a particular app. For non-Store apps, Control Panel opens, where you can uninstall good old desktop programs. You'll see both kinds in the modern Settings app's Apps & Features page. Keep in mind that Windows 10 and 11 have two kinds of applications: traditional desktop apps and modern Microsoft Store (formerly called Windows Store) apps. Set aside a half hour or so for this project if you have a bunch of bloatware.ĭon't forget to take the hatchet to apps you installed yourself but no longer want-and to software you don't want that was installed alongside software you do want. Unfortunately, you can only remove one at a time. When you find junk apps you don't want, select them and click Uninstall. Other good options are to sort by Recent to see if there are any programs you didn't know you installed or by Size, to get rid of very large items you don't need. You can usually find crapware culprits by sorting the list of installed apps on the name of your PC maker. Or just type Programs in the search box next to the Start button. You can also right-click on the Windows logo Start button and choose the top choice Programs and Features. Doing so will immediately uninstall the program. Right-click on any unwanted app tile in Start and choose Uninstall. Even Microsoft is not blameless in this game, as it has included a couple of games and mixed reality software in computers that you may not be interested in. A few years ago, a Lenovo PC we at PCMag tested had nearly 20 so-called helper programs that would occasionally pop up and interrupt what we were doing. Though the situation is improving, an issue with some new computers is they come with a lot of unnecessary software, sometimes called bloatware, crapware, or PUPs for potentially unwanted programs. Do it even if you don't want a big feature update-you can delay those major updates in the same section of Settings. Your PC may run faster after an update since it can include hardware driver updates. Periodically head to Settings > Windows Update to see whether there are any security and reliability updates you should install. Something that is recommended is to keep your OS version up to date, though we didn't list this as a tip because everyone should be doing it regardless. Microsoft categorically does not support the use of registry cleaners (Opens in a new window) for Windows 10. Note that you should beware of those "Speed Up Your PC!" ads for registry cleaners, which often lead to malware. For people with older, low-power machines who want a speed boost but don't care about extra goodies, a couple of the tips that you'll find toward the end of this list do boost system performance at the expense of visual bling. Most of the tips can be done for free, but some involve spending a little cash on software or hardware. Most of our tips show you ways to speed up your Windows system without compromising its appearance and functionality. The problem with a lot of articles that tell you how to speed up Windows is that they tell you to turn off some of the operating system's more fun features, such as visual animations. These tips for speeding up Windows work just as well whether you're running version 10 or 11. Even the most current version of Windows isn't immune to slowdowns, and not everyone is ready to upgrade from Windows 10 to Windows 11 yet. Once you're up and running, however, there are other performance factors to consider.
5/27/2023 0 Comments Ryzom skillsEquipping my pickax I chipped away at the soil to extract raw materials. While gallivanting on my adventures I came across phosphorescent green balls, indicating buried resources. And the camp sites illuminated by torches show off the engine's potential. I believe Ryzom would benefit visually from a perpetual night. Spell effects have a luminous glow that’s gorgeous. However, when the sun set I was impressed. But through a modern lens the systems are not enough to balance the visual crudeness it’s a world that looks better as a static image than it does in transition. Ryzom is impressive for introducing weather patterns and seasons, an ambitious undertaking for a game over a decade old. Invisible barriers remind me that I’m an avatar chained to the confines of the game world’s parameters, a disconcerting notion I'm glad I've never discovered in reality. While wooden fences with posts separated by the width of your character are inhabited by invisible walls.Every cliff face protects players with an unseen force field, forcing players to circumnavigate to level ground. And while shrubbery appears decorated by navigable foliage, they’re actually cubed squares taking up space beyond their visual perimeter. Bushes placed outside the starting encampment are solid objects, impossible to pass. Aged graphics don’t hinder Ultima Online or EverQuest, but some aesthetic properties do hurt Ryzom. Without veiling the world behind an Instagram-like filter, it’s a dull period piece. The custom skill system is my favorite feature, but I am not surprised that other games have avoided it’s intricacies.Īfter playing Ryzom I understand why the majority of screenshots on the game’s site are tilt-shifted. And it does enhance Ryzom’s claim as a true sandbox experience, and I applaud the mechanic for its uniqueness. There are some interesting combinations to be realized, sacrificing range for cast time or vice versa. If you’ve ever built a macro before then the system will feel familiar. While the player isn’t forced to craft the skill themselves, maximizing skill effectiveness requires tinkering like a mad scientist. Purchasing Cold Damage 1 encompasses five stanzas and three credit types. It’s systematically unique but needlessly complex for the masses, and daunting to the unprepared. I created a spell called “Leary’s Special Water,” causing acid damage to the poor creatures surrounding the encampment. Every action has a cost and it must be met with Credits, or regenerative properties such as Stamina. Skills can be crafted through player-end editing, made up of“stanzas”-a sequence of steps that must be properly balanced to be viable. Ryzom presents its mechanics like occultism, forcing you to peel back layers of UI to make any headway. But accumulating skills isn’t as easy as two-clicks and you’re done. Garner enough experience and it’s time to skip off to the trainer to learn new techniques. The more you practice a skill the more fluent you become in its application.

By supporting black-owned gin brands, we can help to promote diversity and inclusivity in the spirits industry, while also enjoying thoughtful and unique spirits. The brand’s name is taken from the Nguni word for distilled beverages, ugologo.Īll of these Black-Owned Gin brands offer unique flavors and blends that are sure to impress any gin enthusiast. They have two gins, Queen Nandi Pink Gin, and Zulu Dry Gin. Gologo Spirits is a South African Black-Owned Gin brand start-up distillery that produces gin. Inspired by 19th-century bartender Thomas Boulot (who was black), the gin is known for its high quality and unique flavor. Tom Bullock’sĪlan Henderson, a former NBA player, founded the Tom Bullock Gin brand in 2021. With distinctive floral and fruity notes, HH Bespoke Gin is made using juniper, lavender, rose hip fruit pulp, cranberry and beach plum.HH Bespoke Gin is made by Harlem Haberdashery, a family-run fashion boutique that pays homage to the rich history of Harlem. America’s first legal black-owned distillery, was founded by Chris Montana and his wife Shanelle. With a focus of sharing the many flavors and cultures of Africa with the world, Spearhead Spirits launched Bayab Gin and Vusa Vodka.ĭu Nord Prominence Gin is a Black-Owned Gin brand made with juniper, orange, lemon and a number of other botanicals for an elegant gin profile. Bayab Ginīayab Gin was created after its founders, Chris Frederick and Damola Timeyin, who noticed a lack of diverse representation in the spirits industry. This smooth favorite should be on your list of must-try drinks if you’re not already a Gin drinker-we suggest trying a Classic Gin Fizz for an extra fruity twist! Flavour profile: Fresh citrus base balanced with Juniper and a floral finish encompassing a complex, yet delicate blend of hints of late summer lavender and rosemary, and exotic spices of cardamom, pimento and fresh dill. Unlike most gins on the market, Indigo has no gluten and calories due to its use of all-natural ingredients InGenious Gin Cabby’s GinĬabby’s is considered London’s first white rum distillery, and their Gin is no different. Here are a few of our favorites: Indoggo Indogoggoįounded by rapper Snoop Dogg, Indoggo is a unique, seven-botanical gin infused with natural fruit flavors. There is a growing number of Black-owned spirits brands. Black-owned spirits companies have been historically underrepresented, despite the fact that Black folks have been integral to the creation and development of many of the spirits we enjoy today. in the actionbar-configuration menu there is a option "use anyup" or something like that in the top section of the menu, if you activate that option the bars will behave like the default ui and wont activate spells if you drag them around.As the spirits industry has grown, it has become increasingly important to support and promote Black-owned businesses in the field. depending on your playstyle, using OnAnyDown can decrease the delay between your casts and thus increase your dps. rdx-actionbars are configured to call the action when a button is pressed down aka OnAnyDown, the default-ui and most other actionbar-mods activate the action when the button is released aka OnAnyUp. The "ability activates when swapping" thing has to do with the AnyUp/AnyDown option. Its a bit messy in the screenshot, and the actionbar floating is disabled now.Īlso when i want to swap my spells around, they get activated, is there a way to be able to pick them up from the action bar withouth actually using them? My logical conclusion from this is that when using the demonic form i have to use bonusbar 1.īut i tried every type of actionbar from the list, but it just doesn't switch. If i read correctly, is for rogues and priests (stealth and shadowform)īonusbar 1, 2 and 3 are for the warrrior's stances, and 1 trough 4 are for the druids shapes. I've tried a lot of things, used the states from the guides, but i can't seem to get it to work. Now i got the problem that action bar 1 doesn't switch when using demonic presence. I'm using the action bar package for openRDX and switched my locks spec yesterday from destro to demo. 5/27/2023 0 Comments Smartsvn ignore folder contentsRepository path: /svn/ for https, / for network.

He did not wait even 24 hours after his first email before closing communications and deciding to go through with his plan at 3am my time. I told him I would have to consult an attorney regardless. He also offered me his services helping write software for the Kiwi Farms. I saw this as a legally and morally dubious offer at best, entrapment at worst, so I declined.

You can run qBittorrent on Windows operating systems. You can imagine a bounding box as a box that surrounds the object like the image below. One of the simplest forms of collision detection uses what is known as Axis-Aligned Bounding Box (AABB). How can we make a gameObject know when it hits something? That’s the job of the collision detection mechanism. Even worse, it can’t even know whether it hit it or not! Looking good, but our ball isn’t bouncing when hitting the screen edge yet. Vector2 newPosition = (Vector2)transform.position movement Īnd look at our little ball! Going beyond infinity, where no ball set foot before. Vector2 movement = direction * speed * ltaTime So, by solving both equations we can find X and Y! That leaves us with two unknown variables b and c, corresponding to our desired values Y and X, respectively. Θ is our desired angle, which is 45°, and c is the length of our vector, which is 1! What does it have to do with finding our values? Well, take a closer look at the first two equations ( sin and cos). Notice how the vector v ends on the unit circle, having a magnitude of 1.Ī familiar shape arises! That makes a right triangle, which has a lot of useful properties, especially in trigonometry. Let’s name our desired vector as v, and let’s extract its X and Y components as follows: Ok, we know the direction and the magnitude, but we still don’t know what are the values for the X and Y components. But the cool thing is, if we have a vector that starts in the origin and ends inside the circumference of the unit circle, it’ll have a magnitude of 1! This is known as a unit vector. In reality, it’s just a circle that has a radius of 1. That way, it has to have a magnitude of 1.Īre you familiar with the unit circle? If not, take a look at the image below. We already know which direction we want the ball to go (at an angle of 45°), but what about the magnitude? As this vector will only store direction, it shouldn’t interfere with the speed when multiplying both. We’re going to solve this question with the power of (please don’t go away) trigonometry!! The question is, how can we set an angle, like 45°, if we can only specify the X and Y components of a vector? We need a way to get those with only the angle (direction) and the magnitude (length). When the game starts (and the ball script is enabled), this method will be called and our direction set.įor now, let’s make the ball go to the right and up, diagonally with an angle of 45°, like the image below. Getting a $$ degrees angle is of course possible by computing $arccos(\frac)$.The ball will need an initial direction to starting moving, so where can we set it? The Start method is perfect for this. In the 3D case, your two vectors would be on some plane (the plane that you can get its normal from the cross-product of the two vectors). So there is no real sense in a value in a range larger than $$. The angle from the front will be the opposite of the angle that you see from the back. The dot product will therefore basically measure the length of that vector, but with the correct sign attached to it.īefore reading this answer - Imagine your angle in a 3D space - you can look at it from the "front" and from the "back" (front and back are defined by you). This might be easier to implement in some APIs, and gives a different perspective on what's going on here: The cross product is proportional to the sine of the angle, and will lie perpendicular to the plane, hence be a multiple of $n$. The determinant could also be expressed as the triple product: One condition for this to work is that the normal vector $n$ has unit length. In this case, you can adapt the 2D computation above, including $n$ into the determinant to make its size $3\times3$. Then the axis of rotation will be in direction $n$ as well, and the orientation of $n$ will fix an orientation for that axis. One special case is the case where your vectors are not placed arbitrarily, but lie within a plane with a known normal vector $n$. In this case, the dot product of the normalized vectors is enough to compute angles. One common convention is to let angles be always positive, and to orient the axis in such a way that it fits a positive angle. That axis of rotation does not come with a fixed orientation, which means that you cannot uniquely fix the direction of the angle of rotation either. In 3D, two arbitrarily placed vectors define their own axis of rotation, perpendicular to both. Many programming languages provide a function atan2 for this purpose, e.g.: dot = x1*x2 y1*y2 # dot productĪngle = atan2(det, dot) # atan2(y, x) or atan2(sin, cos) And if you know the cosine and the sine, then you can compute the angle. Just like the dot product is proportional to the cosine of the angle, the determinant is proprortional to its sine. I'm adapting my answer on Stack Overflow. |
