![]() What’s scarier than an encounter with true evil that could actually happen?īelow, we’ve compiled a list of 13 of the best possession horror movies that are Vatican-level terrifying. Pope Francis has declared that “we should not think of the devil as a myth, a representation, a symbol, a figure of speech or an idea,” but rather as a “personal being who assails us.” The thought that demons and the devil himself could be preying on the souls of the living is like the scariest horror movie come to life-which is precisely why possession movies are so effective. had fewer than 15 known Catholic exorcists in 2011, and well over 100 in 2018. According to writer Mike Mariani’s findings, the U.S. The increase has reportedly led to the Catholic Church training new priests in Chicago, Rome, and Manila on how to properly perform the exorcism ceremony for real-life battles against demonic possession. I’m just going to leave that there and let you finish my final thoughts on your own.In 2018, The Atlantic published an article about a recent and alarming trend showing an uptick in exorcism requests. As if the mind-shatteringly awful ending wasn’t bad enough, the final achievement is titled “See the names of Gods.” This is awarded for seeing the credits. Unfortunately, the entire premise is essentially the theft of what Hideo Kojima’s team created, and nothing is built on top of that. If you allow yourself to be scared, this game creates some reliable tension. I don’t understand people who watch a horror movie, laugh at it the whole time, and then talk about how the movie just wasn’t scary. Could you please elaborate? There’s blood in the hallway, she’s standing in this one spot in the house at some point - why? Aside from the awful voice acting of the protagonist, we don’t get much else. Sadly, that’s likely because the developers did not create anything original with Evil Inside.ĭid I enjoy being scared? Yeah, I did. Unfortunately, most of the scares feel completely random not just because they’re jump scares, but because there’s no story thread. Angry, dead woman is angry because she’s dead. I get it. I felt fear, I just wish it was for more intelligent reasons besides sudden loud noises and randomly appearing people. To be fair, Evil Inside absolutely establishes a horrifying mood rooted in cheap jump scares, unsettling music and sounds, and adequate use of lighting. Akin to downing one Pixy Stix after another, Evil Inside’s reliance on jump scares is beyond lazy, but to say I wasn’t uneasy, had goosebumps, and felt my heart rate rise would be a lie. The scariest thing about this hallway? More gameplay. I’m assuming it’s because she died in a well.Īside from brazen similarities in the house’s architectural design to its inspiration, P.T., Evil Inside forces players to go to one end of the hallway after solving a “puzzle” and then enter the same hallway again. Brilliant! I wish I had thought of it. For the most part a walking simulator, Evil Inside occasionally requires players to retrace their steps five times until they find a clickable in the environment to trigger a variable and open the door to the basement. Repeat this a bunch of times, and enjoy the shocking ending after one hour of game time. is now dead. Dead like a woman thrown into a well. Because if we can’t take advantage of people’s emotions and inability to move on, then what’s the point in even having a first-world economy?Įvil Inside is what’s on the tin: You’re stuck in a house because your mom is dead and really, really mad. Like, to the point where she can only stand to be in your face for a quarter of a second, scream really loudly, and then disappear again. Evil Inside has received a bit of marketing leaning heavily into the still hopeless P.T.craze. Any cursory interest I still had in P.T. Three things are certain in life: death, taxes, and the fact that skinny women in nightgowns with long black hair are terrifying. ![]() Project Runway airs Thursdays at 9/8c on Lifetime. He auditioned after an old professor told him he should try his chances and sent him the application link.īrandon already has more than 30,000 followers on his Instagram, where he regularly shows off pictures of his work. ![]() Kee told the newspaper he watched previous episodes of the show to learn how it worked and realized the one thing he needed to work on was his time management - something he did before filming started. Miller said: “As his collection developed, so did he. He grew and saw the potential of where this could take him he put in the time needed and was receptive to feedback and was professional.” The pair worked together on a menswear collection Kee designed while he was studying that was based on aviation flight suits. The director of the Academy’s School of Fashion, Gary Miller, previously told its newspaper how Kee was “easygoing, worked hard and was open to new ideas and techniques”. While studying both had their collections shown in the Academy’s runway shows at New York Fashion Week. Fellow Project Runway Season 16 contestant Amy Bond, who was eliminated in episode 9, also studied there, graduating in 2011. In a stream, it was said that Vivian Nixon also auditioned for one of the Cherubs, indirectly hinted to be either be Keenie or Deerie as Vivziepop mentioned taking over the role.He graduated from The Academy of Arts with a bachelor’s in fashion design - specifically menswear design - just last year.She shares the same voice actor with Deerie, with both of them being voiced by the series creator, Vivienne Medrano.Like her colleagues, Keenie's name derives from a country famous for shepherding.It is currently unknown if Keenie is still on Earth or somewhere else. The designer, who was the second-runner-up, hasn’t had the easiest. The members of C.H.E.R.U.B are the first cherubs shown to be banished from Heaven. Kenley Collins first gained notoriety with her ’40s-inspired fashion and fiery attitude during Project Runway ‘s fifth season.It is currently unknown if this is a feat unique to only her or a selected few, or if every other Cherub has the same ability. Despite it still functioning as intended, those who are banished from Heaven are banned from re-entering from said portal. Portal Summoning: As demonstrated in her debut episode, she was the one to summon a portal back to Heaven for herself and her fellow co-workers.Musical Talent: In the beginning of the episode " C.H.E.R.U.B", she is able to sing the lyrics on rhythm.Archery: Along with her co-workers, Keenie is seen to be proficient with her crossbow being able to shoot many arrows at high speeds. ![]() Enhanced Strength: Keenie is seen effortlessly lifting a large boulder during the C.H.E.R.U.B commercial.When released from the crossbow, these arrows leave behind a visible trail of bright sparkling golden light. Weapon Summoning: Like all other Cherubs, Keenie has the ability to summon an angelic crossbow that's unique to her, as well as golden arrows to load it with.Flight: Along with all the other abilities of Cherubs, Keenie can fly due to her wings, and can fly quite quickly and is swift with her wings in battle, even though her wings are quite small. ![]() She has also shown to be the most aggressive and violent of the cherubs, kickstarting the brawl between them and the imps when Millie pushed her too far. Ironically, she is shown to cuss when angered to a high point, even though she still considers I.M.P's actions and slang inappropriate, along with chastising Collin for accidentally using the Lord's name in vain even though she has used far worse language than he has. However, she appears to have total and absolute disregard for Hell and its inhabitants, as she refers to them as disgusting, loathsome beasts that "shitty dead people" tread on. She doesn't, however, seem to be totally invested in the lives of her clients, and instead appears to only want to help them out of obligation to her job rather than out of sympathy.īeing an angel, Keenie has a very modest nature having low tolerance to what she finds indecent, such as Blitzo making an inappropriate joke or when Collin uses the Lord's name in vain. She is shown to be very dedicated for her work both as an angel and in C.H.E.R.U.B, not hesitating to head into combat if outside forces don't go her way. Keenie poses with a very kind demeanor and attempts to inspire others through her job. Just like all the other Cherubs, all of Keenie's outlines are done in purple. Her eyes have purple pupils with pink irises, and she wears a yellow dress with a pink hem and a bow.

You'll also find parts strewn about underground that you can use to build new weapons. Underground, you'll find magnets, bombs and boxing gloves which can be used to defeat enemies. You have a number of weapons and items at your disposal outside of just your drill. You've got to avoid this by taking out food and enemies under ground. Should they get their hands on food, they float up to the surface and are then consumed by the boss character, which then evolves into a more difficult form. Enemies move around underground with you, collecting food. Strategically driving these stakes into the ground will cause pieces of the island to break off into the ocean, hopefully taking the boss with it. ![]() This is accomplished by digging out the dirt beneath large stakes stuck into the ground, driving them deeper.

There are over 35+ racetracks available across the US, so if you find a track near you, it’s definitely an experience you will never forget. My instructor (like all the instructors there) was actually a professional driver and made the experience that much more fun and comfortable by giving proper guidance and encouragement to go fast and handle this beast with precision. It was amazing to feel that acceleration, handle that much speed, and really test the braking and cornering abilities. I know I was able to reach 132mph in just a short amount of time. Most drivers will blow past 100+ miles per hour. I mean, I REALLY had to apply the brakes, but that’s what these cars were built for… SPEED and performance! The Speed It wasn’t until I slowed down to take the next turn that I realized just how fast we were going. It took me by surprise, but I instantly wanted more. I have to admit, I’ve never felt power and speed like that before. Once I was guided through the first lap and hit the big straight-away, I got the go ahead from the instructor to put the pedal to the medal and give it everything the Hurricane had. The track included a variety of turns, straight-aways, elevation changes, camber, curbing, and safety features. ![]() After that, we were guided to the racetrack where we got fitted for helmets and waited to meet our instructor who would then guide us each through the track so we could let loose and let-r-rip! I was expecting to “GO FAST”, but I wasn’t expecting to feel that amazing sensation and become addicted to this experience.Īs soon as I arrived, it was a quick and seamless process of signing some waivers and going through a quick 15 minute class session on how to drive the cars, safety features, how to read the cones for directions, as well as what to expect from the driving experience. You can also do a package deal where you can drive 2, 3, or even the full fleet of cars. They also have several other amazing options for exotic supercars: Ferrari, McLaren, Porsche, Corvette Stingray, Mustang Shelby GT500, Dodge Challenger Hellcat, and a Nissan GT.

Well if you have that urge to (as Ricky Bobby would say) “GO FAST!”, boy do I have just the fix for you! The awesome team over at The Xtreme Xperience invited me out to test drive one of my all time favorite cars, the Lamborghini Hurricane. The parent repository is now pretty slim it contains the. The commit points to the current version of HEAD in the checked out submodule, which as can be seen here is e9ed329101157ce9be5dc1c2639096bd82d3fa05.

The submodule (sub repository) can evolve at its own pace, with its own checkouts, and the parent can refer to it by a fixed hash. Git submodules works these two concepts together, by treating a submodule as a logically checked out directory in another repository, but referring it to it by a pointer rather than a full checkout. bigjobbies file suggested before.) Since they are referenced by hash, as long as you can acquire the hash then you will be able to restore the asset. ![]() However, tags can change (although they're not supposed to) and conventions can be circumvented.Īnother way to do it is to store a pointer to the assets. If you're storing these as separate git repositories, how do you ensure that they are kept in sync with each other? Well, you could use tags and rely on convention to ensure that you can acquire the same version of the assets. The history of one will therefore not affect history of another. The obvious solution to this problem is to store source code (and other compressible assets) in one Git repository, and then store large media assets (sound effects, in-movie videos etc.) in another Git repository. Files above 512Mb (by default) are stored without any delta compressions to previous versions (though they are deflated at storage time). Git also has a configuration variable, core.bigFileThreshold, which can be used to set the limit at which files are stored as-is without performing any delta comparisons. Typically, large binary assets (such as audio files, movies or even images if they've been saved in a compressed format) share little of the same binary data under the covers. ![]() Although Git provides a good delta encoding for existing files, these tend to only work if the binary data is relatively similar. The reason one might want to do that is to avoid a checkout from the server taking a significant period of time, or taking up additional space once the clone has been made. In the previous post, I wrote about a tounge-in-cheek extension called git bigjobbies the purposes of which was to store large binaries in a repository without them being part of the main branch (and thus, not appearing in the history).

Located eight miles northwest of downtown Miami, MIA is a major hub in the Southeast as well as a gateway to Latin America and other international destinations. ![]() It is very important to carry out careful storage design to avoid the above situation. The virtual machine waiting for IO cannot do other work, so high I/O waiting time means that performance will definitely decrease. Virtual machine waiting for disk IO and virtual machine CPU idle have a very different impact on performance. Because the centralized shared storage architecture will cause all virtual machine disks to be accessed through the same location, the storage controller of the array and the disk overload will easily occur, leaving only the virtual machine waiting for the response from the storage. Virtual machine disk performance is limited by the number and type of array disks and the number of virtual machines running on it. Disk performanceĭisk performance is often a silent performance killer. Therefore, a virtual machine running on a CPU-limited server may face low network throughput because the CPU cannot quickly respond to requests. Virtual machines that perform a large number of network transfers, virtual machines, and data packet transfers all consume CPU time. For the connection to the external physical network, you must ensure that the host has the fastest physical network card. Network bandwidth includes two aspects: one is the bandwidth between the virtual machine and the virtual switch, and the other is the bandwidth between the virtual switch and the external network. On the other hand, when the virtual machine operating system uses unused memory as a disk cache, it will significantly reduce the performance requirements of the disk system, so there is a trade-off. Allocating additional memory will increase the risk of recycling. The wisest thing is to allocate only the memory needed to complete the work for the virtual machine. The more memory the virtual machine is reclaimed, the greater the corresponding risk. When the physical memory occupied by the virtual machine is reclaimed, there is a risk that it will affect the performance of the virtual machine. After the physical memory is completely used up, it is necessary to determine which virtual machines can reserve the physical memory and which virtual machines need to release the physical memory. ![]() RAM resources are usually limited, so you need to be extra careful when allocating RAM to virtual machines. Because only multi-threaded applications can effectively use multiple vCPUs. However, assigning more than two vCPUs to a virtual machine does not necessarily make the application run faster. If the virtual machine needs to take up a lot of CPU time, consider assigning a second vCPU to the virtual machine. Therefore, the higher the CPU frequency, the higher the running speed of the virtual machine, and the greater the number of vCPUs will help improve the performance of the application. CPUĮach vCPU of a virtual machine runs on only one physical core. ![]() Otherwise, unreasonable allocation of resources will result in poor performance of applications in the virtual machine. The relationship between these resources should be considered when planning a virtual machine. ![]() Virtual machine resources involve multiple aspects: CPU, memory, network, and disk. It is more convenient and faster to run the program The virtual system can simulate the same environment as the existing operating system, while the virtual machine can simulate other types of operating systems and the virtual machine needs to simulate the underlying hardware instructions, so the application program runs much slower than the virtual system. Starting the virtual machine system does not need to be time-consuming like starting the windows system. The virtual machine system is different from the traditional virtual machine in: The virtual machine system will not reduce the performance of the computer. And it is a type of operating system that can flexibly switch between the existing system and the virtual mirrors. It can install and run software independently, save data, and has its own independent desktop without any impact on the real system. After entering the virtual machine system, all operations are carried out in this brand new independent virtual machine system. It has the same function as a real windows system. The virtual machine system generates a new virtual mirror of the existing operating system. It can operate on virtual machines like physical machines. Each virtual machine has its own CMOS, hard disk and operating system. When creating a virtual machine in a computer, part of the hard disk and memory capacity of the physical machine needs to be used as the hard disk and memory capacity of the virtual machine. The work done in a physical computer can be realized in a virtual machine. Virtual Machine is a complete computer system with complete hardware system functions that is simulated by software and runs in a completely isolated environment. |
