Parisian Cat: A filthy restaurant in peril, the old scientist receives a prototype cleaning robot, the cat, from his cousin.Tasty Planet Forever has eight different worlds to experience, each with a different playable character and unique story, each world has twelve levels (except for Paris, which has eleven): At the end of it all the Goo starts eating universes, which now look as small as quarks, as the Goo starts eating the quarks they turn into atoms, crumbs, furniture, hills, buildings, planets, stars, galaxies, universes, right back around for a Forever Feast. It kept eating until it could eat furniture, walls, airlock doors, astronauts, rocks, martian hills and buildings, and eventually escaping into space to eat planets, stars, space creatures, galaxies, and noodle monsters. It started getting big enough to eat computer parts, robot dogs, towels, and even Red Shirts. It begins eating microscopic quarks, atoms, and molecules, before eating more microscopic materials and beings, eventually getting big enough to eat crumbs, nuts, and bolts. In these small droplets of water lies a microscopic Grey Goo, even smaller than an atom. On the planet Mars, some ice samples are carried indoors by an astronaut with some of it melting off. It starts out eating small bits of food and crumbs, and later trash, pests, air conditioners, vehicles, and even buildings, factories, and floating islands. Penguins have evolved to fly and one sets out to take revenge on humans for bringing the world to this state. In the future, the ice caps have melted and the world is heavily polluted. In Australia, when the habitat is overrun with invasive species', a dingo sets out to rid the area of invasive species, eating many different invasive animal species before starting to eat other things like bushes, trucks, and houses, which in a way makes them an invasive species. Full of wrath, the basking shark starts eating lots of exotic fish and plants, even eating logs, cabins, trucks, boats, and finally a Shark Hunter. In the Pacific Ocean, a basking shark overhears a conversation about how basking sharks are killed for money and that humans want to drive them to extinction. It was accidentally released by an ignorant bystander, and from then it started eating pollen, small creatures, and plants before growing big enough to eat birds, drones, people, and cars, eventually eating the whole park, the city, and even the moon and the earth. It wasn't ready to be released though, due to its seeming aggression towards smaller creatures and abnormal growth abilities. In a large city, the bee population is rapidly decreasing, so a beekeeper invents a "Super Bee" that can pollinate frequently and is resistant to colony collapse. However one small round rat can eat much more than just mines, eating all sorts of small creatures, plants, and eventually eating poachers, their camps, and even a small airport. In Africa, land mines are scattered all over the place, which has severely decreased the elephant population, however, several rats have been selectively bred to eat minefields and make them safe for elephant travel. The octopus decides to get revenge on humans for polluting the oceans, and starts consuming marine life, plants, and eventually people, vehicles, and buildings, eventually eating a seaside town and a large pile of trash. In the Caribbean Sea, an octopus is sitting near the shore, until it starts getting covered in garbage. The chef tells the cat to eat everything, and it does so, however the cat has the power to grow to any size to get the job done, and since it was told to eat everything, it starts growing larger, eating the kitchen, the restaurant and eventually growing big enough to eat all of Paris. In Paris, when a restaurant is dirty and customers are about to come through the door, one of the chefs opens up a box for a prototype cleaning robot resembling a tiny cat he received from his cousins. Tasty Planet Forever has eight different playable characters each with their own world and backstory.

And while the interface may take a little getting used to, even a beginner can master the essentials relatively easily. It also works on almost every platform, with versions for Windows, Mac and Linux. There's a wide range of tools to create professional-looking videos, including some fairly advanced audio-editing options, VFX, color adjustments and more. Lightworks is advanced enough that the Pro version has been used to create multiple award-winning movies including the likes of Pulp Fiction and The Wolf of Wall Street, but the free version is only marginally less full-featured. You can also purchase a number of add-on packs, starting at around $10, to add even more functionality to the program, or upgrade to either the Creator ($6.25/month) or Pro ($10/month) for more options. Other great features include the ability to create your own lightsaber battles, 360-degree video editing and lens distortion correction from action cameras. And, it has a light interface - but if you prefer a dark interface, that'll set you back $9. It also supports VEGAS files and effects. Hitfilm Express supports resolutions up to 4K, GPU-accelerated decoding on Nvidia, AMD, and Intel graphics cards (on PCs only), changes to the interface, and native support for Dolby AC3 audio. That's all on top of the many other features already present in this premium-feeling package: there's an auto stabilizer to make bumpy footage look smoother, motion tracking, a color picker to selectively adjust colors, and a crop & pan tool - otherwise known as the Ken Burns effect. The latest version, Hitfilm Express 2022.1, includes an array of enhancements such as clipping masks, a lasso mask feature and a bunch of in-app tutorials. Its high-energy style appeals to budding filmmakers who want to put a special touch on a personal event or get creative with a video blog, but it's still easy enough for the adventurous friends-and-family crowd. Hitfilm Express is the best free video editing software package. May have slight learning curve for newcomers The best free video editing software you can download today But if you need just the basics, you've come to the right place. Of course, there are some features that can only be found in paid software packages be sure to check out our picks for the best video editing software under $100 too. However, you won't get advanced features such as 360-degree video editing and special effects here. iMovie supports 4K video, and has some good tools for smoothing shaky video, adding titles, and even soundtracks from music in your iTunes library. Mac users who only need a simple video editor will find that Apple iMovie is the best free video editing software, because of its strong integration with Apple's operating system and easy-to-grasp editing tools. These include such features as 360-degree video editing, 3D titles, advanced color-grading tools and LUTs, and even audio tools such as Doppler Shift and noise reduction. Lightworks is another great option, offering plenty of advanced tools completely free, but with the caveat that exports are limited to 720p. While HitFilm is free, you can pay for 30 add-on packs, which range in price from around $15 up to $50. It works with both Macs and PCs and has a revamped interface that's powerful but easy to use and customizable to your needs. View Deal On to the best free video editing softwareĪfter testing numerous suites, we think the best free video editing software overall is HitFilm Express. Once the spark plug has been gapped be careful not to change the gap by dropping it or by banging it against the engine during installation. the side not shrouded by the side electrode). The gap should be adjusted by only moving the ground electrode. To close the gap lightly tap the bottom of the plug against a hard surface. Indexing of plugs upon installation involves installing the spark plug so that the open area of the gap (i.e. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium, be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. The gap should never be opened by prying against the center electrode. If the gap is too small use a proper gapping tool to slowly force the ground away from the center electrode. When checking the gap be gentle and do not force the tool. It's best to use a set of feeler gauges or a wire spark plug gap checking tool as these are more accurate than the disc type and less likely to break the electrode. When checking or setting the gap its important to use the proper tools in order to prevent damage to the plug. You should feel slight drag as the tool passes through the spark plug gap, but it should not feel forced. You are looking for the snug fit, not tight, not loose. Do this carefully so that you don’t damage them. If you do need to gap a plug that has multiple grounds contact the manufacturer for appropriate instructions. To check the spark plug gap, insert the keyring tool, wire tool, or feeler gauges into the gap between the two electrodes. Some applications (typically very high-performance and rotary motors) have spark plugs that have no ground strap while others have multiple ground straps, these are generally very difficult to gap and should be set correctly from the factory. Some platinum and iridium plugs have warnings on them not to change the gap, however these also need to be checked and properly set. Some spark plugs come pre-gapped, but these should still be checked as the gap can get changed during the course of normal shipping and handling. The proper specifications can be found in the owner's manual or on a tag under the hood. Setting the spark plug gap correctly can improve fuel economy and power. The gap is the distance between the center electrode of the spark plug and its ground strap. If you’re having trouble starting your engine, and it cranks for a long time before starting or doesn’t start at all, it may be due to an incorrect spark plug gap. Knowing how to gap spark plugs is an important part of a tune-up procedure. Adding forced induction or high-compression pistons to an engine will usually require the spark plug gap to be closed slightly. If the gap is not set correctly, the spark might not ignite the air-fuel mixture correctly, which can cause the engine to struggle or fail to start at all. He’s not the only one either: the nightmare is shared among many men in their 30s and 40s, who all appear to Vincent as sheep and are killed off in in the real world each night via weakening as a constant reminder of the fate that awaits you should you fail. The catch is, if he dies during the nightmare, he dies in real life ala Nightmare on Elm Street. With its initial primary theme of freedom and a new story-line surrounding one of the most touching LGTBQ+ relationships in mainstream gaming to-date, Full Body sees Catherine age from a highly enjoyable yet flawed niche title to an unadulterated classic.įor those unfamiliar with the original, Catherine: Full Body follows nine (or ten) days in the life Vincent Brooks, a 32-year-old engineer with deep-seated fears of commitment and change, as he begins to experience nightmares where he must frantically climb diabolically complex and crumbling block towers in order to flee from monstrous representations of the shackles (or responsibilities) that threaten his freedom. Whether you want to play for three hours or 300, you want a visual novel or hardcore puzzle platformer (or both), Full Body can and will be bent into the shape you wish it to take. From the brilliant addition and incorporation of a third love interest in Rin, more than double the number of puzzles of the original, five new endings, new music, more than 20 new animated cut-scenes, new liquor trivia, new bar patrons to talk to, and competitive and cooperative local and online multiplayer, Full Body spoils the player with an abundance of content and ways to experience it. Catherine in its original form never felt like an incomplete experience, but Full Body retroactively makes it one. To say that it delivers on this promise would be an understatement. Catherine was not built for mainstream success, and yet nearly nine years later, it’s sold seven-figure numbers and now receives an enhanced port in the form of Catherine: Full Body (the first project from new Atlus subsidiary studio Studio Zero) described as a richer, more mature experience. Known primarily for their work on the Persona series, Catherine stands as the outlier, or the black sheep, among their games together: short, brutally challenging, with a focus on multiple endings and score chasing for replay value and not a level-up or high schooler in sight. Back in 2011, developer Atlus released Catherine, the unique and innovative brainchild of dream team Katsura Hashino (direction and scenario), Yuichiro Tanaka (scenario), Shigenori Soejima (art) and Shoji Meguro (music). Law enforcement released Russell – who had arrived home after Arthurs murdered Oneschuk and Himmelman – at the scene, only to arrest him again two days later in Key Largo, Florida. Arthurs said he shot both men because they failed to respect his Muslim faith.ĭuring their search of Russell and Arthurs’ apartment, police found bomb-making equipment and hate literature. Law enforcement officers found the bodies of two men, later identified as Oneschuk and Himmelman, with gunshot wounds to the upper body and head. As police escorted Arthurs to a squad car after arranging with him to release the hostages in the store, Arthurs replied to an officer’s request regarding if anyone else was hurt, saying “The people in the apartment, but they aren’t hurt, they’re dead.”Īrthurs directed police to the apartment, which he shared with AWD co-founder Brandon Russell. bombings against Muslim-majority countries. During that time, Arthurs, a self-proclaimed convert to radical Islam from neo-Nazism, made repeated references to U.S. According to a police report filed on May 20, 2017, officers arrested Arthurs after he brandished a firearm and held multiple customers and employees hostage at the Green Planet Smoke Shop in Tampa. The murder charges stem from an attack on May 19, 2017, when Arthurs murdered two people and held three others hostage. Arthurs underwent treatment, and in June 2022, the court found Arthurs capable of standing trial and resumed proceedings. In early 2018, two court-appointed doctors told the court that they believed Arthurs suffered from a mental illness and was unfit to stand trial at the time, according to court records. In that document, Arthurs’ lawyers said that while he “knew what he was doing, Defendant did not know it was wrong” and cited his diagnosis of schizoaffective and autism spectrum disorders. It also represents an about-face for his defense team, which had stated its intention to rely on an insanity plea in a notice of intent filed with the court on Feb. Hatewatch reached out to Arthurs via his lawyer, who declined to comment on the case.Īrthurs’ guilty plea brings an abrupt end to what would have been a two-week jury trial, originally set to take place from May 8-19 at the Hillsborough County Court in Tampa.

The Emmy Award-winning Saturday morning cartoon series of the 1970s comes to life in the Summer Circle Theatre courtyard June 15-18. The musical is a celebration of songs like “Just a Bill,” “Lolly, Lolly, Lolly,” and “Conjunction Junction” that have taught history, grammar, math and more to generations for over 50 years.

Beyond theatrical productions, SCT is committed to offering free programming and special activities to create a summer destination for arts, education, and entertainment. Summer Circle Theatre provides a professional venue for MSU students to present shows of varying styles using the talents of community members and professional artists. This season’s programming is designed to attract audiences of all ages. Since 1960, the MSU Department of Theatre has heralded the unofficial start of summer with its Summer Circle Theatre program, which presents free, accessible theatre using the talents of MSU students and faculty. The Michigan State University Department of Theatre’s 2023 Summer Circle Theatre, which runs June 15-25, is in its 61 st season offering free outdoor theatre for all ages. If you prepay your mortgage, your money is tied up in home equity, meaning you will have less access to cash for major life expenses and unforeseen emergencies. Do the math to see if prepaying your mortgage offers the best payoff. If you bought a home when interest rates were 4% or lower, saving on interest is unlikely to provide as much of a return on your money as you could get through investments. If you have high-interest credit card debt, personal loans or auto loans, it’s generally a wiser move to apply extra payments to those expenses first. Mortgage payments often carry lower interest rates than other types of debt. Your mortgage balance may not accurately reflect the amount you owe-there may be additional fees and penalties. Should I Pay Off My Mortgage Early?īefore you make the decision to pay off your mortgage early, check with your loan servicer to confirm the remainder of your payout. Even if you have the funds available to pay off your mortgage early, whether or not doing so makes sense warrants some assessment. If you’re thinking about getting a mortgage and plan to pay it off early in some way, you may want to ask your lender about an open-end loan.Īlso, not all borrowers are in the same financial situation. For instance, closed-end loans-which make up most standard mortgages-can restrict prepayments entirely or require borrowers to pay a heavy penalty if they pay off or refinance their loan within a certain number of years (typically three to five). However, some types of mortgages come with prepayment penalties. After all, not having that recurring monthly payment while also getting to own your home free and clear can be a liberating feeling. Many people with the resources may think paying off their mortgage early makes sense. Current mortgage payment: The monthly payment, principal and interest, based on your original mortgage amount (doesn’t include current homeowners insurance or taxes).This rate will be lower than your annual percentage rate (APR), which does include these fees. Annual interest rate: The simple interest rate on your loan that doesn’t include private mortgage insurance, the origination fee or point(s) paid at the beginning of the mortgage.This is not to be confused with the remaining principal balance. Remaining mortgage amount: The amount you still have financed, including interest.Original mortgage term: The length of your original mortgage in years (15-, 20- and 30- year terms are the most common).Years remaining: The number of years left on your mortgage term.Current mortgage payment: The monthly payment, principal and interest, based on your original mortgage amount (doesn’t include current homeowners insurance or taxes)Īs you use the calculator, there are some mortgage terms that you’ll need to know.Annual interest rate: The simple interest rate on your loan that doesn’t include private mortgage insurance, the origination fee or point(s) paid at the beginning of the mortgage (this is why this rate is lower than your annual percentage rate (APR), which does include these fees).Remaining mortgage amount: The amount you first financed (includes interest, so don’t confuse it with the remaining principal balance).

Microsoft Authenticator - Also similar to Google Authenticator, but works especially well with Microsoft servicesĪbove all else, security is our main concern.LastPass Authenticator - Similar to Google Authenticator, but works within the LastPass ecosystem.andOTP - An open-source alternative that has more features than the competition.Google Authenticator - A widely adopted standard across major websites. Authy - Easy to use, feature-rich and supports multi-device sync.The code is usually a six-digit time-based, one-time password (TOTP).īefore getting into how we chose them, here’s a rundown of our top five picks: Every time you log in, your app will automatically generate a code, which you’ll need to enter to unlock your account. After turning on 2FA on your account, you can scan a QR code to tie that account to your app. Two-factor apps use one-time passwords (OTP) as your second factor. We’ll also briefly touch on hardware keys that use either a hardware token or fingerprint scanner to approve your login. These apps work on iOS and Android, usually providing you with single-use codes or push notifications on your mobile device. We have a deep dive into what two-factor authentication is if you need more information.įor the purposes of this guide, we’re focusing on 2FA apps like Microsoft Authenticator and Authy. There are some differences between factors, and there are even differences in how one-time codes are generated and sent to you. It works by combining two of the factors listed above, so you might use your password as your main factor and a 2FA app as a secondary factor. Most websites support 2FA in some form, including Amazon, PayPal, Reddit and all major social media platforms.
Synchronization using a counting semaphore: Let's say you have 3 tasks - #1 and 2 you want executed after 3. Read More Airtable Enhance team collaboration and workflow in a seamless manner Start Free Trial Get Buyer Checklist (1,513 Ratings) Airtable pricing: Starts at 10.0. Of what use is a multi-stage-lock in mutual exclusion or synchronization? Ryver vs ClickUp ClickUp Alternatives Compare 96 The SW Score ranks the products within a particular category on a variety of parameters, to provide a definite ranking system. Let's look at what this is implying - a lock with more than one value? So open, closed, and. hint hint : do i necessarily only need to use one semaphore?)Ĭounting semaphore: A semaphore with more than one value. (Think about how else one could use semaphores to achieve mutual exclusion. Now, is it possible to have greater concurrency? Depends on the critical sections. So each thread is using the same semaphore to provide mutual exclusion for its two critical sections. The mutual exclusion is quite simple as well - m1 and m2 cannot enter the critical section at the same time. Public static Semaphore Bouncer //constructor A semaphore is a generalization of a lock (or, the other way around, a lock is a special case of a semaphore). What they are A spinlock is one possible implementation of a lock, namely one that is implemented by busy waiting ('spinning'). Here is a very pedagogic example in C# :-) using System Spinlock and semaphore differ mainly in four things: 1. For example, to limit the number of simultaneous calls to a database in an application. It's simply a way to limit the number of consumers for a specific resource. If the club is full no one is allowed to enter, but as soon as one person leaves another person might enter. There are a dedicated number of people that are allowed in the club at once. Frankly, its more than a bit surprising they made it into the standard as they are.Think of semaphores as bouncers at a nightclub. Limitation two can be mitigated by careful coding, assuming control over all code that will use a given semaphore. Limitation one above makes POSIX shared semaphores unusable in a real-world system without a guarantee that uncatchable signals can never be sent. Two shared semaphores with the same name operating independently defeats the purpose of shared semaphores. Process 2 calls sem_open on the same semaphore between the sem_unlink and sem_close calls of process 1, and (according to documentation) gets a brand new semaphore with the same name, but in a different state than process 1. This process can still use the semaphore just like unlinking an open file before closing it. For example a process calls sem_open, then sem_unlink before sem_close. The implication is that there can be more than one shared semaphore with the same name, but in different states. This means that a KILL signal to the wrong process at the wrong time can deadlock an entire system of interacting processes until reboot.Īnother disadvantage is the use of file semantics for POSIX semaphores. No such tools or even mechanisms are specified for POSIX IPC, though on Linux these resources can often be found under /shm. The POSIX section on SysV IPC does specify the ipcs and ipcrm tools to list and manipulate global SysV IPC resources. There is also no POSIX way of listing the semaphores in the OS to attempt to identify and clean them up. This lack of cleanup can lead to zombie semaphores which will cause any other or subsequent process that tries to use them to deadlock. A semaphore manages an internal counter which is decremented by each acquire() call and incremented by each release() call. POSIX semaphores provide no mechanism to wake a waiting process when a different process dies while holding a semaphore lock. Two major problems with POSIX shared/named semaphores used in separate processes (not threads): POSIX semaphores provide a mechanism for process-wide semaphores rather.It has been said that POSIX semaphore performance is better than. System V semaphores, when creating a semaphore object, creates an array of Smt1500rmi2u vs sua1500rmi2u, Makeovers for girls, Motorola mb140r singapore.The scalability of POSIX semaphores (using unnamed semaphores) is much.From a usage perspective, System V semaphores are clumsy, while POSIX.Initialization and creation of semaphores is atomic (from the user's.It’s another locking mechanism, not a signaling mechanism like a semaphore. Another well-known process synchronization tool is a mutex. This value defines the number of processes allowed to access the shared resource concurrently. POSIX semaphores do not allow manipulation of semaphore permissions, A counting semaphore can take any positive integer value.One marked difference between the System V and POSIX semaphore. Now, let’s look at the roller coaster in Figure 9.7. In the discussions to follow, we will use the approximation that transformations are frictionless. Friction causes the loss of some useful energy. However, note that because of the work done by friction, these energy–work transformations are never perfect. If all the work done on an object is used to raise the object above the ground, the amount work equals the object’s gain in gravitational potential energy. This is generally true for any object raised above the ground. The amount of work required to raise the TV from point A to point B is equal to the amount of gravitational potential energy the TV gains from its height above the ground. Remember that both work and energy are expressed in joules. For example, when an object that has gravitational potential energy falls, its energy is converted to kinetic energy. You will see that this stored energy can either be used to do work or can be transformed into kinetic energy. Remember that the potential part of the term means that energy has been stored and can be used at another time. Quite a bit of potential energy is gained by a roller coaster car and its passengers when they are raised to the top of the first hill. We will also see that, in a closed system, the sum of these forms of energy remains constant. In this section we will see how energy is transformed from one of these forms to the other. We saw earlier that mechanical energy can be either potential or kinetic. Mechanical Energy and Conservation of Energy Explain that energy lost to friction is really transforming kinetic energy at the macroscopic level to kinetic energy at the atomic level. Try to get students to understand heat and temperature at a molecular level. Start a discussion about how other useful forms of energy also end up as wasted heat, such as light, sound, and electricity. Identify heat generated by friction as the usual explanation for apparent violations of the law. Discuss the law of conservation of energy and dispel any misconceptions related to this law, such is the idea that moving objects just slow down naturally. Explain how the general definition of energy as the ability to do work makes perfect sense in terms of either form of mechanical energy. Begin by distinguishing mechanical energy from other forms of energy. In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Work and Energy, as well as the following standards: (D) demonstrate and apply the laws of conservation of energy and conservation of momentum in one dimension.(B) investigate examples of kinetic and potential energy and their transformations.The student knows that changes occur within a physical system and applies the laws of conservation of energy and momentum. The learning objectives in this section will help your students master the following standards: |
