We’ve put together a list of some most overused resume verbs - and what you can replace them with. Making your resume sound more interesting is easier said than done. Examples of resume power words with synonyms If you’re trying to avoid this - and who isn’t? - here’s a complete guide to power verbs, including the best ones to use on your resume. After all, whose eyes wouldn’t glaze over after reading “created” seven times in a row? Let’s face it - scanning resumes isn’t the most riveting job to begin with, and no hiring manager wants to spend their day reading the exact same word over and over. But what happens when you run out of ideas? And this, in turn, will make sure that your writing makes more of an impact.Every resume accomplishment needs a strong action verb. As part of this service, we will highlight and suggest replacements for “weak” language like “good” and “bad” if it is misused. Another option is to have your work proofread by the experts. The same applies to these words in other forms of critical writing. The answer, then, is to remember that academic writing requires an explanation of our judgments. But to demonstrate our understanding, we’d also need to explain why it’s bad and how we reached that conclusion. For example, if we were writing about management techniques, we might say, “Unpaid overtime is bad for staff morale.” That is an evaluation. This is because they’re evaluative rather than descriptive. It’s okay to use words like “good” and “bad” in academic writing, but they’re not usually enough by themselves. As with “good,” this makes it important to check the definition of synonyms for “bad.” “Good” and “Bad” in Academic Writing There are other uses of “bad” not described here, such as describing an injured body part (e.g., a “bad back”) or rotten food (e.g., “bad meat”).

"Will you give me the refund I am eligible to receive or break the FonePaw Refund Policy and not refund me?". After weeks of trying to get a straight answer from them, they refused to answer my simple yes or no question. I hope there are decent people working at FonePaw and that she's not a common representation of the other employees at FonePaw.īut after reading others reviews about FonePaw, I believe the whole company is likely led by crooks who are out to steal your money and time. I hope she quits her job and finds another where she doesn't willfully hurt people for a living. EMILY WATSON at FonePaw is a liar and a thief. To protect them, I'll tell them to never buy anything from FonePaw. I'm going to warn everyone I should about FonePaw. She didn't even have the decency to admit it. She cheated me out of my money, and worse, she sneakily lied, deceived and led me on, trying to tire me out until I gave up on all of our communications. I emailed with EMILY WATSON from in about 40 emails and in customer support tickets I submitted on /contact. I tried to get help from them for the technical malfunctions of the screen recorder I bought from FonePaw for 70 days. THIS MESSAGE IS TO WARN AND PROTECT POTENTIAL FONEPAW CUSTOMERS AGAINST BEING ROBBEDįONEPAW IS A SCAM. This company should NOT be allowed to exist based on their lack of knowledge of their products and more importantly their HORRIBLE customer service. The problem with their detailed instructions was it requesting logs for the FonePaw Data Recovery product which is not what I purchased or even mentioned in any of my communications. On August 1,2022, I received a response telling me that they wanted to do further troubleshooting and gave me detailed instructions on what to do to provide them the logs needed to troubleshoot the problem. On July 19,2022, I asked for the status of the refund. Please wait patiently." that was on July 11,2022. After 1 month, I finally received this response: "We have verified your order information, your situation meets our company's refund policy condition. There is no distinction on any of their material that indicates that group text messages are not included in the backups. That does NOT show me how to backup group messages. It takes anywhere from 7 to 10 days to get a response and then the response is to view the product videos on their website or on YouTube. I have tried working with the customer support team and it is almost impossible. It will not backup your group messages so you will not be able to restore them. Sin θ m = nmλ where m is the order of the fringe. Instead of specifying the interslit spacing d, we normally cite the number of slits per unit length, n. In all cases, if the slit separation is d, the condition for a strong maximum is the same as for Young's experiment, i.e.ĭ sin θ m = mλ where m is the order of the fringe. So let's now look at fringes with large numbers of slits. So, as we increase the number of slits, the width of the fringes becomes narrower, their brightness increases, and the subsidiary maxima are proportionally less important. Remember that the intensity goes as the square of the amplitude, so the intensity of the bright fringes represented in the diagrams above would go as 2 2 : 3 2 : 4 2 = 4 : 9: 16 = 1 : 2.25 : 4. The figure below shows the atomic emission spectrum of hydrogen. Note also that the height of the maxima increases, because more slits contribute to it. An atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate it into the different frequencies of light it contains. For two slits, the range of φ is 2π = 4π/2 for three slits it is 4π/3, for four slits it is 4π/4 and, for N slits it is 4π/ N. the spacing between the zeros on either side. For four slits, the first zero occurs at φ = π/2 and there are two small subsidiary maxima.Ĭonsider the width of the large maximum, i.e. With three slits having the same spacing, the same varation in θ and thus φ takes us from central maximum, to zero at φ = 2π/3, to a small subsidiary maximum at φ = 2π/2 = π, to zero at φ = 4π/3 and back to a maximum at φ = 2π. With two slits, as φ varies from 0 to 2π, the phasor sum rotates so that its amplitude goes from maximum to zero to maximum. In Diffraction, we saw that the phase difference at angle φ θ between rays from two sources distance a apart was φ = 2π a sin θ/ λ. In each case, the angle between adjacent phasors scans from 0 to 2π. As the angle on the diffraction pattern is varied, the angle between the phasors varies and, at the same time, the black vertical line scans, in synchrony, across the plot of intensity. The distance between the two ends of the figure is the amplitude of the resultant pattern, and the intensity, which is graphed at right, is proportional to the square of the amplitude. In each of the animations below, we see at left the phasor diagram for the appropriate number of sources. To understand the pattern produced by a diffraction grating with many slits, let's begin with Young's experiment (two slits) and add more. The images below show the dispersion patterns made with the same grating for a sodium lamp, a mercury lamp, an incandescent lamp and a candle. The sketch at right shows (top) a light source illuminating a grating, with the dispersed image projected on a distant screen. Patterns with monochromatic and broad band sources.This page supports the multimedia tutorial Diffraction. A grating disperses light of different wavelengths to give, for any wavelength, a narrow fringe. A grating is a set of equally spaced, narrow, parallel sources. Diffraction gratings allow optical spectroscopy. The new Lovecraftian Wrath of the Elder Gods table is a particular favorite.īeyond those, you have a pack of three Dreamworks' Animation-themed tables (more difficult than you might expect), a My Little Pony table (colorful and delightful), a World War Z table (fun), Snoopy and Garfield tables (also fun), a Universal Films series (which might as well be called the Spielberg tables), and a treasure trove of classic Williams Pinball tables that have been meticulously transferred from the real world to the digital realm. The Zen originals are some of the very best tables available, and I worry that people might skip over them because they aren't as eye-catching as some of the licensed stuff. But if you are just stopping there, you are missing out on some of the best experiences Pinball FX has to offer. There are huge swaths of Star Wars tables, of course, and the aforementioned Marvel tables (thank God I have access to the Moon Knight table again). The available tables themselves have quite a variety of themes. In other words, success at one pinball table does not equal success in all. You can play one table for forty hours until you completely master it, just to start a new table and have it hand you your face on a bloody platter. Each table has it's own mechanics, it's own method of scoring, and they all "feel" very, very different from one another. I consider each of these tables to be their own separate fully-featured game, much in the way that Galaga or Gauntlet are games. In all, there are 86 tables currently available for purchase in Pinball FX, including the sudden (and very welcome) return of most of the old Marvel tables of yore (notable exceptions are The Avengers table and the Deadpool table). Players that download Pinball FX get one table for free, and they are able to purchase individual tables or table packs to add to their collection. I'm loath to call Pinball FX a "game", as I think of it much more as a platform. So for this review, I'll focus more on how the Pinball FX experience is structured, with the express understanding that the tables are all in the 8.5-10 region, if we were to score them individually. Suffice to say, the individual tables are beyond excellent, and Zen is the best in the business. There is no need to yammer on about it and beat a dead horse. I've gone on record in at least five different reviews about how much I love and respect the work Zen Studios does on these tables. The endless jamming of the R1 and L1 buttons on my DualSense controllers in this case has made simple activities like doing the dishes and writing into wincingly painful tasks. There is simply nothing else like it in gaming, and yes, I will merrily damage my body in its pursuit. But that does not stop my addictive personality from locking in on a Zen pinball table and keeping me there for hours on end, sweating, swearing, and chasing the ever-elusive dopamine reward of a new high score. I have stated numerous times over the years that I am not a great pinball player. There are few games anymore that inspire that old "one more try" addiction that lurks inside my 1980s arcade-trained brain, but Zen's pinball games are among them. I can always tell that Zen Studios has released a new pinball title by the aching soreness in my forearms. Before going straight into the broken wall, turn left and kill the ambushing Hollow Infantry around the corner then return to the hole and drop into a room with 3 Hollows (one of them faking death). To the left of the clearing is a mist, which leads through a wooded tunnel and into ruins. Jumping over to it nets you Throwing Knives and a Soul of a Nameless Soldier. Back at the base of the ladder that lead up, to the right you can spot a platform with items on it. Jumping across the gap to the ledge brings you to a corpse with Shortsword and a Soul of a Lost Undead. Dropping down to the ledge below leads to the Hollow Royal Soldier who was throwing Firebombs. Cross the planks at the top of the tower and go up to the right to a corpse with a Soul of a Nameless Soldier. Avoid damage by getting on the ladder and immediately getting off. When you get on the ladder a Hollow Infantry will start coming down the ladder ahead of you. To the right is an opening to a cliff, and to the left a ladder up a moss covered tower. There are several corpses on the ground holding various items including: a Human Effigy, Green Blossom, 2x Broken Straight Sword, and a Lifegem. Going up the ladder leads into an open area with a whopping twelve Hollow Infantry playing dead, and a Hollow Royal Soldier throwing firebombs from the walkway above. Across the planks and up the hill brings you to a ladder. Dropping down to the stream below the plank bridge brings you to a corpse with Soul of a Lost Undead. Moving ahead across a plank bridge there is an Archer and three more Hollows. Just ahead of the tree, up a short path on the right is a clearing in which you'll find The Crestfallen's Retreat bonfire, where you will be attacked by another Hollow. In the creek, you'll find an Ogre roaming around, which won't aggro until you come within reach. Upon your arrival, two Hollow Infantries wander immediately ahead with an additional two beyond, around the bend of the creek. If not, simply head back up the wooden planks and drop down from the rocks above. To get to the Forest from here, simply continue forward, and follow the stream left. Beyond in the stream is a corpse with a Homeward Bone and Soul of a Lost Undead, if you are confident in your jumping abilities, you can make the jump from the platform holding the chest. Past the bridge, going to the right leads to the Forest of Fallen Giants, while to the left you'll find two long planks to a large stone with a chest that contains a Human Effigy. The path opens up to a cave with a wooden bridge that spans a stream. Pulling the lever to the right of the gate, opens it. Continue into the darkness, making a U-turn on the first right of the main path in, you'll find an iron chest (chest is a Mimic in NG+) with a Rusted Coin. Turn around and proceed down the hallway, to find a dead end to the right and to the left a large gated door. This leads down to an underground stone ramp-way. Starting at the Majula bonfire, facing the coast, you should notice a crumbled wall separating the hill and a big doorway, on the right if not, look for the torch sconce marking the entrance. 1x Red Ironclad Soldier (near Soldiers Rest Bonfire)įull Forest of Fallen Giants Walkthrough Accessing From Majula.NG+ 1x Red Hollow (just before Pursuer Boss Fight).NG+ 1x Red Ironclad Soldier (Near Exploding Barrel Courtyard).NG+ 2x Red Phantoms (In court yard of the Kings door).Syan Soldier (Stands guard outside Kings Door).Rebel's Greatshield (in Flame Lizard caverns - Winner of Dark Souls Shield Competition design).Bonfires: The Crestfallen's Retreat, Cardinal Tower, Soldier's Rest, The Place Unbeknownst.

The iPhone 12 Pro Max topped our best camera phone list based on our testing.īoth iPhone 12 Pro models offer Apple ProRAW, which combines Apple’s multiframe image processing and computational photography to let photographers shoot in RAW format. This helps improve autofocus by up to 6x in low light while also enabling Night mode protraits, something the iPhone 12 and iPhone 12 mini can't pull off.Īpple's iPhone 12 Pro Max is even ahead of the iPhone Pro, thanks to a larger sensor in the wide camera that delivers an 87% improvement in low light. Plus, only the iPhone 12 Pro Max boasts sensor-shift optical image stabilization for reducing blur. The iPhone 12 Pro and iPhone 12 Pro also benefit from a LiDAR sensor. The iPhone 12 and iPhone 12 mini are limited to 5x digital zoom. The iPhone 12 Pro offers a 2x telephoto zoom with 10x digital zoom, while the iPhone 12 Pro Max extends that to 2.5x optical zoom and 12x digital zoom. iPhone 12 vs mini vs Pro vs Pro Max: Prices and storage The 6.1-inch iPhone 12 and iPhone 12 Pro had a release date of October 23, 2020, while the 5.4-inch iPhone 12 mini and 6.7-inch iPhone 12 Pro Max arrived November 13, 2020. The iPhone 12 lineup was released in two stages. IPhone 12 vs mini vs Pro vs Pro Max: Release dates So if you’re looking for the most phone for your money, the $999 iPhone 12 Pro is your best bet, with just the right mix of size, features, and price. The Max is a great choice as well but likely a bit too big for most people, while the mini sacrifices a bit too much in the battery department to reach such a small size. For the extra camera features and design touches, we think that’s well worth the extra money. Our pick: The difference between the 128GB iPhone 12 and 128GB iPhone 12 Pro is just $120 this year versus $250 with the iPhone 11. And Apple applies that to the tiers as well, so they all cost $50 less than last year: $1,099/$1,199 for 256GB and $1,299/$1,399 for 512GB. When you factor in the higher storage capacity, you’re actually getting a better value. The iPhone 12 costs $999 and the iPhone 12 Max costs $1,099 just like last year. Those prices don’t apply to the Pro models, however. Storage upgrades are still $50 for 128GB and $100 for 256GB. T-Mobile and SIM-free buyers will still pay the higher prices. However, Verizon and AT&T customers will get a special carrier discount of $30 to bring the price down. When you buy a new iPhone 12 mini or 12, you’ll see that the retail price is actually $729 and $829, respectively. For another, that’s not actually the price. For one, that’s for the 5.4-inch model, so a comparable iPhone 12 costs $100 more than the iPhone 11. iPhone 12: Price and conclusionĪpple touted that the iPhone 12 starts at the same $699 as the iPhone 11, but that’s only part of the story. And the enhancements in iOS 15 will tap into 5G’s full potential. Our pick: We don’t recommend switching plans just to get 5G, but if your plan supports it, any of these phones will deliver great speeds. Enhanced connectivity will let more app and system experiences tap into higher speeds and the iPhone 12 will automatically prioritize 5G when Wi-Fi connectivity is slow. IOS 15 will bring some enhancements to 5G across all models of the iPhone 12. If you have an older phone plan, you’ll need to switch to a newer, likely more expensive one, and you’re extremely unlikely to get anywhere near the promised multi-gig speeds that Verizon claimed to deliver during the event. That said, 5G is still very much in its infancy right now. One more thing, it is FREE!!! You can get it from the App Store or at mactracker. Whither you want to be the ultimate Mac historian, use it for reference, or just want to see how far Macs have grown, the Mactracker database is for you.

But wait - there's more! As Juan Julian in Miami New Drama's production of Nilo Cruz's Anna in the Tropics, he commanded the stage alongside veteran actors in a play that won the 2003 Pulitzer Prize for Drama. This season, he turned in a gold medal-worthy performance as professional swimmer Ray in Ronnie Larsen's production of Red Speedo the Foundry in Wilton Manors and made his GableStage debut playing comical dual roles in El Huracán. The 2019 New World School of the Arts grad made his professional debut at Zoetic Stage in 2021's Frankenstein, proving himself a talent to be reckoned with as a hideous creature, skinny, contorted, and covered in makeup that rendered his body and face in scars and stitches. But casting directors don't just want him for his body. In the past year, he has been seen in almost every local professional theater production that calls for a good-looking Latino. Gabriell Salgado wins this category three times over. It is a separate component that only interacts with the cloud platform. cloud-controller-managerĬloud-controller-manager allows us to connect our on-premises Kubernetes cluster to the cloud-hosted Kubernetes cluster. We need to set up a proper backup plan for etcd so if something happens to the cluster we can restore the backup and come back to the business quickly. It is totally different open-source product backed by the Cloud Native Computing Foundation. If other control plane’s components have to access etcd, it has to go through kube-api-server. etcd is only accessible by Kube-api-server. It is a consistent, distributed, and a highly-available key-value store. For example, whenever we create a new namespace, we need a service account and access token to access it so these controllers are responsible for creating default accounts and API access token for the new namespace.Įtcd is the default data store for Kubernetes that stores all cluster data. Service account and token controllers: – Responsible for creating default accounts and the API access token.Endpoints controller: – it creates the Endpoints object, for example, to expose the pod externally we need to join it to a service.Replication controller: – It ensures that the correct numbers of pods are running for every replication controller object in the cluster.Node controller: – it manages nodes and keeps an eye on available nodes in the cluster and responds if any node goes down.It includes node controller, replication controller, endpoints controller, and service account and token controllers. It ensures that the current state matches the desired state, if the current state does not match the desired state, it makes appropriate changes to the cluster to achieve the desired state. It is actually comprised of four processes and runs as a single process to reduce complexity. Kube-controller-manager is responsible for running controller processes. If more than one node has the same score then it chooses one randomly. Once it filters out all feasible nodes, it assigns a score to each feasible node based on active score rules and it runs the pod on the node which has the highest score. In filtering, Kube-scheduler finds a feasible node by running checks like node has enough available resource that is mentioned for this pod. Kube-scheduler uses 2 step process to select a node for the pod in the cluster, filtering, and scoring. Feasible node is the node that fulfills all the requirements for a pod to schedule. If there is no node available that meets the specified requirements then the pod is not deployed and it remains unscheduled until the Kube-scheduler does not find a feasible node. by specifying affinity, anti-specification or constraint in the YAML file before deploying a pod or a deployment. However, it is possible to schedule a pod or a group of pods on a specific node, in a specific zone or as per node label, etc. Kube-scheduler is responsible for scheduling newly created pods to the best available nodes to run in the cluster. There is more than one api-server that can be deployed horizontally to balance the traffic using a load balancer. It services REST operations and provides a front end for the Kubernetes control plane that exposes the Kubernetes API through which other components can communicate to the cluster. Kube-api-server is the main component of the control plane as all traffic goes through api-server, other components of the control plane also connect to api-server if they have to communicate with ‘etcd’ datastore as only Kube-api-server can communicate with ‘etcd’. Kubernetes Control Plane has five components as below: Let’s understand about different components of Kubernetes Control Plane. ‘kube-apiserver’ communicate with other control plane’s component that is ‘etcd’ data store and it fetches the data and sends back to the console via HTTPs and we see the details of nodes on our terminal. Here, when we run this command, it makes an API call through HTTPs to the cluster and it is handled by ‘kube-apiserver’. $ kubectl get nodes: The kubectl is a command-line tool that we use to interact with the Kubernetes cluster and manage it. Let’s understand the working of Kubernetes control plane by an example, given below: – Web development, programming languages, Software testing & others |
