If you’d rather work more directly with the files on your device, you can scroll the mouse wheel or click the top button on the right side of the screen to get more direct control.Īll of this works in a familiar way that you’ll recognize from iTunes, which makes it easy to get used to the way AnyTrans works without much time spent learning a new program. Content to iTunes will copy files from your device into your iTunes library, which is really only useful if you’ve purchased something through your device and want to update your library. Merge Device, Clone Device and Content to Device will all be useful when you’re upgrading your old iOS device to the latest model, but I only have one iOS device currently available for testing purposes. You can store files there and copy them onto other computers, just as you would with a normal thumb drive, although you will need to have AnyTrans installed on both computers in order to access your files easily. This is most useful for copying photos or videos from your device to your computer for use in other programs.įast Drive is much more interesting, as it allows you to use the free space on your iOS device as a normal thumb drive. There are some very useful functions here, but the three most commonly used ones are probably going to be Add Content, Content to PC and Fast Drive.Īdd Content is pretty self-explanatory – it allows you to add files from your PC, although you can only add them using a standard ‘File Open’ dialog box, which can be frustratingly slow if you want to add a large number of files to your device.Ĭontent to PC is also fairly obvious and simple to use, allowing you to transfer any content from your various device libraries to your PC. ![]() Once your device has been initialized, you’re taken straight to the Device Content tab and given some friendly shortcuts to common tasks. As you connect it and the software begins to recognize it, the background animates in a nice twist on the standard boring progress bar. Once you’ve installed the software and opened the program, you’re presented with a screen prompting you to connect your device. For simplicity, the screenshots and instructions below are taken from AnyTrans for Windows, but we have tested AnyTrans for Mac as well, and JP will point out the differences when necessary. The navigation is quite similar for the two versions, except for some minor user interface differences. Note: AnyTrans for iOS is available for both PC and Mac. I constantly update the music stored on it, so I’m very familiar with the iOS file management process.ĭisclaimer: iMobie has not had any editorial input on the content of this article and I did not receive my copy of the software from them through any type of promotion, so there’s no reason for me to be unfairly biased. My old iPhone has been converted into a digital white noise machine, and it is a dedicated music player. This has given me quite a lot of perspective on what makes some software good and some bad, and even though I have since moved to the Android ecosystem for my main smartphone, I still use my iPhone for various tasks around the house. I’ve been using iPhones for almost a decade, and my experience with software extends much further back. What I Don’t Like: Most reliable with devices permanently unlocked. Download web videos directly to your device. You can add new files to your device, but adding multiple files or folders at once is a slow process when compared to working with files already in your iTunes library. Instead, you’re restricted from working with the files in your existing library, although you can still modify the library as normal with iTunes while AnyTrans is installed and running. The only issue I discovered that would prevent me from ignoring iTunes entirely and relying on AnyTrans was that it cannot add files to your iTunes library. It’s not exactly an iTunes replacement, but it will handle the majority of the daily file management tasks that iTunes does. It can even integrate with your iCloud account to manage your online storage, and download videos from the web for offline use on your device. AnyTrans is a file manager for iOS devices that can copy any type of media from your computer to your iOS device or from your device to your computer, as well as create and manage your device backups.

There's other more obvious ones: Ingrid + Skirmisher Talisman + Speedsuit + her own Speed increase + chance of melee AP/the Sage can move across the entire battle field efficiently and abuse her Killer Instinct Fedir and weapon debuff mods/reload cards and the Leech is an Eddie Barrage without Eddie's presence the Herald and the Conjuction can be not just free actions but bonus AP (i run on Judith - didn't like the speed decrease from the Behemoth) Eddie, crit, Endless Bandolier and Inspiration never needs to reload. ![]() Alternatively you can also drop Bruisers and melee in rather than out for shenanigans. Stick and Move can really help to put Nocturne into the perfect spot then unleash a big signature on now Shocked enemies if you're willing to drop the invis. ![]() Nocturne's invisible on Translocate pairs great with melee (Ingrid and Celestine) allowing them to get in and go helter skelter with their AP then porting them out to safety whilst being untargetable herself and potentially Shocking + Slowing the group as well. Unfortunately with a typical 3 man squad i personally don't like running 2 Bruisers but looks like she'll benefit again from the Bombardier's Brace for this combo. Judith's Sticky Grenade that does double damage on Knocked Down targets also pairs really well with the other Bruisers - Ingrid's AOE signature or Fedir whom can use the stuck person as a grenade themselves, tossing them into a pack and hitting groups. This further pairs with anyone running the Herald card, and gives him synergy with a third card like the Tyrant to build stress as well as heroes that like attacking Marked targets with the skill upgrade on evade (Eddie's Bullseye and Light 'Em Up). The skill that gives an evade procs on the same shot if Flash ammo's blind occurs. Lateef with Flash ammo and the cards the Gambler and Great Wind has turned him into an unkillable, Inspired tank for me that can deal out huge Running Shots. Haven't got the full roster but here's the ones i've enjoyed: Even a weak attack (like several cards provide) can be useful in that respect, if your other characters don't have anything better to do with the AP. But she also benefits from folks who can make lots of attacks (either because like Ingrid they have a ton of potential AP to spare or because like Eddy their attacks can hit multiple targets), because each attack causes a point of stress (two if cursed), which adds up quickly even on tough enemies. So of course she benefits from stress-related cards like the Sadist (which gives her stress reduction and healing whenever an enemy stress-breaks, which is what she wants to be doing anyway) or the Monument (basically an AoE stress bomb with a cooldown). ![]() In addition, her Occult Gambit let's her get extra action points at the cost of stress (effectively every use gives her a 50% chance of a free AP and a 50% chance of gaining 3 stress). Everything about her kit is centered around attacking the enemy stress bar instead of their HP (although she can certainly do that as well), with curse (doubling the stress an enemy takes for the round), poison (dealing extra stress), and a Signature that recharges on stress kills. I'll start with the crazy stress-monger Celestine. Any interesting or powerful character combinations (either with other characters or with specific cards) you've found? ![]() If you work in an organization, you use the hostname to access that host. The domain name is like an entire organization, and the hostname is the computer within that organization. People usually intermix hostname and domain name terms, but both are different. What is the difference between a domain name and a hostname? These uniquely identifiable names are "Fully Qualified Domain Name" (FQDN). On the internet, computers can be uniquely assigned using a combination of hostname and domain. In that case, you must supplement the hostname with the information that tells where a host is located on the internet. However, suppose you want that particular computer locally available and available on the internet. The hostname is used to distinguish the device within the local network. In network systems, the hostname is the nickname of the computer or device. And hostname is the name of the host that distinguishes it from others. In general, the host is the person that entertains the guest. On the other hand, digital devices understand the numeric language.Ī DNS lookup is performed to convert the human-written domain name to the corresponding IP address and direct the user to the exact destination on the internet. That is why the domain names are in a human-readable format. Humans understand the alphanumeric language, and it's easy to memorize anything in that format. What is a hostname, and what is the purpose of a hostname? The IP location finder only provides you with the IP and location of the public IP assigned to your device. The private IP address is local and is assigned to your network's computers, tablets, and other devices. The public IP address is accessible outside the network to communicate with the world. ![]() In addition, you can even perform the IPv4 to IPv6 conversion or IPv6 to IPv4 conversion as per your use.Įach type of IP address is further divided into two versions. People are moving towards the IPv6 address. But due to the shortage of IPv4 addresses. The second one is IPv6, 128-bit long, which is still not widely used. There are two types of IP addresses the first is IPv4, 32-bit long, and most commonly used. You can even get the user's location by tracking the IP address's exact location. But you can get information about its user from an IP address. Mostly, people do not give much weight to an IP address. You can check your device with the check my IP tool. Without the IP address, you cannot connect to the internet. It is separated by periods and is allocated to each device, including computers, tablets, mobiles, or any other digital device part of the TCP/IP-based network. The IP address (Internet Protocol Address) is a unique numeric string identifier. Internet protocol is the guidelines or rules and regulations that ensure and regulate internet connectivity.ĭigital devices understand the numeric language. In general, the IP address means the Internet protocol address. And perform various activities around the clock.Įach device connected to the internet has a unique numeric identifier, called an IP address.

If you use this work schedule, you’ll usually work at the same time as others on your team. Other countries, like France, might have other legal definitions of what “full time” means-so always check with your internal legal and HR teams if you haven’t already. For example, in the United States, a full time schedule means team members work 40 hours per week-traditionally from 9 a.m. Some of the most common types of work schedules include: Full-timeĪ full-time schedule means your team members are working a traditional work week. Always make sure to follow local and federal laws when assigning work schedules. But before making any changes to your team’s work schedule, make sure to check with your internal legal team. Your team members may appreciate flexibility with their day instead of sticking to a 9-to-5 schedule. While your company may stick to a traditional full-time schedule, it can be helpful to familiarize yourself with other work schedule types. ![]() A software engineer may work the night shift to keep systems running for daytime workers, and an operations manager may have extended shift schedules to watch over manufacturing.

I let you dissect the code and try to understand the puzzle.ĬSS only Triangular pattern by Temani Afif CodePen.ĬSS only triangular pattern by Temani Afif CodePen. For these, I will not give you a figure to illustrate each gradient. Here are two more patterns with triangular shapes. Similar to the Zig-Zag pattern, we consider an offset for the second gradient using background-position to get the following code: -s: 120px /* control the size */Ĭonic-gradient(from 150deg at 50% 33%,#FA6900 60deg,#0000 0)Ĭonic-gradient(from -30deg at 50% 66%,#D95B43 60deg,#ECD078 0) īackground-size: var(-s) calc(var(-s)/1.154) Gradients are known to have such issues so we always update values that way to fix them. Note that in the previous demos, I am using 90.5deg instead of 0deg to avoid jagged edges. Zig Zag background pattern by Temani Afif CodePen. The code can be optimized by introducing CSS variables: -s: 100px /* control the size */ The 50px 0 is nothing but the background-position of the second gradient and 50px is half the background-size. To get what we want, we need to shift the second gradient (or the first one) as shown in (2) to have the following code: background:Ĭonic-gradient(from 135deg,#ECEDDC 90deg,#29AB87 0) 50px 0 The (1) in the above illustrates the following code: background:Ĭonic-gradient(from -45deg,#ECEDDC 90deg,#0000 0),Ĭonic-gradient(from 135deg,#ECEDDC 90deg,#29AB87 0) Not the best pattern but it illustrates the technique we are going to use in this article to build better ones! If we define a background-size, we create a pattern: The yellow is filling the remaining space which is also 135deg ( 360deg - 225deg). The blue starts from where the red ends and continues until 225deg so it’s filling 135deg. We still have the same center but no transition between the colors. This will avoid us writing the same value twice. ![]() We can still do better like below background: conic-gradient(at 75% 25%, red 90deg, blue 0 225deg, yellow 0)īy specifying 0 (a value smaller than the previous one) the browser will automatically make it equal to the previous one. Note the use of the same angle between two colors ( 90deg and 225deg). To do this, we need to make the color start where the previous one ends: background: conic-gradient(at 75% 25%, red 90deg, blue 90deg 225deg, yellow 225deg) In most cases, we don’t need a smooth transition but rather “hard stop” colors. We place the center point at X=75% and Y=25% then we create a color transition between red, blue, and yellow. Let’s take a basic example to see how it works: background: conic-gradient(at 75% 25%, red, blue, yellow) ![]() The only minor drawback of the Elite 50 is the inability to use 12.5, 22.5, 32.5, and 42.5 lb weights. You will love that the Elite 50 upgrades effortlessly to Elite 70 and Elite 90 with Stage 2 and 3 kits, respectively. However, with the adder weights, you can customize the lb increments to as low as 2.5, which is fantastic if you are just getting started with weights. The Elite 50 dumbbell from PowerBlock is the first in this series and comes with 5 to 50 lbs per dumbbell. The components of the center handle have different weights – the empty handle is 5 lbs, while the nested block is 10 lbs and the removable adder weights are 2.5 lbs each. Moreover, the Elite Series blocks are also compatible with each other – meaning that you can transform Elite 50 into 70 and so on, with the Elite expansion kits. The adjustable dumbbells in this series are manufactured exclusively in the US. The Elite Series dumbbells are also color-coded, which indicates the weight, and they look more like a clunky box. The dumbbells in this series have a distinct look because of the pair of padded wrist supports on the handle. PowerBlock was initially called the Elite Series, which you might be familiar with – Classic Series. In terms of appearance, the Sport 24 is the only model in the Sport series that bears a similar look to the iconic color-coded band against a full body of grey. The lb increments of the Sport 24 are 3 lbs, and so are the empty handle and the blocks, which weigh 3 lbs each. It is also a non-expandable set so expect no more than 24 lbs with this dumbbell. In the Sports Series, the 24 is the smallest model. ![]() The empty handles of the Sport 50 are 10 lbs, while the nested block is 5 lbs and does not come with adder weights. It has 5 lb increments making this model the right choice if you prefer to bulk up your biceps. Sport 50 is a non-expandable model with weights between 5 and 50 lbs, which does not exceed that limit. This model in the Sport Series comes with a pair of 2.4 lb adder weights so that you can customize it for smaller increments. The straight handle of the EXP weighs 5 lbs when it is empty, and the nested block is 10 lbs. The EXP model is the only one from the Sport Series that is expandable, so they are compatible with Stage 1, 2, and 3 sets.īecause of this feature, the Sport EXP works similarly to the Elite 50, meaning you can upgrade the EXP Stage 1 set of 50 to 70 lbs using the Stage 2 kit and up to 90 lbs with Stage 3 kits. PowerBlock also imports the Sport models instead of manufacturing them in the states. Unlike the other series, these adjustable dumbbells do not have support bars on the handle. The dumbbells in this series are also separate models as opposed to a single group in the Elite Series. PowerBlock’s Sport Series have a defined contour, giving them a sleek and modern appearance. Please join me as I discuss each dumbbell model so that you can make an informed decision. The above table summarizes the main similarities and differences between the dumbbells from PowerBlock.

Sadly, the three actors who played the Marlboro Man died of lung cancer. The genius of the ad is that at the same time there was a rising realisation that this thing will kill you, it was identified with a character who was, on the face of it, indomitable.” James Twitchell, author of 20 Ads that Shook the World, said the Marlboro Man was an achievement because it found success at a time when Americans were learning that cigarettes were genuinely dangerous, addictive products that could kill you. He supported the cowboy campaign and later had a hand in Marlboro’s introduction of the hard, flip-top cigarette packet – an invention that, by creating a ritual around opening a pack, contributed almost as much to the addictive nature of cigarettes as nicotine. Louis B Cheskin, whose original specialism was the psychological use of colour, proposed that the Marlboro packaging should suggest a medal worn around the neck as an unconscious cue of masculinity. ![]() It worked and the Marlboro Man became as famous as other Leo Burnett creations like Pillsbury Dough Boy and the Jolly Green Giant. Next came the long-running cowboy series, all in an attempt to convince the public that men could demand a filter too. First came the series with men with a tattoo on their smoking hand, tattoos were masculine then. The question then became how to make this cigarette appeal to men? The Leo Burnett advertising agency in Chicago was consulted and came up with campaigns that showed Real Men smoking filtered Marlboro cigarettes. Filters were generally decided to be the answer but Real Men, which was where the sales dollars were, didn’t smoke a filter cigarette. In the 1950’s there began a suspicion that smoking cigarettes may be linked to lung disease. The reason? Leo Burnett’s Marlboro Man and the abiding power of marketing, even in an industry where advertising itself is virtually forbidden. That dominance is mirrored to a lesser extent in just about every other territory the brand is marketed, as other cigarettes see brand share erode in favour of Big Red. In its home territory, more than four out of every ten cigarettes smoked is a Marlboro, the brand’s highest-ever level of market share. Ironically, as the tobacco industry comes under ever more intense regulatory pressure, Marlboro is still going from strength to strength at least in terms of market share. Ownership is split primarily between what are now two entirely separate companies: Philip Morris USA and Philip Morris International. Marlboro is far and away the world’s best-known and biggest-selling cigarette, with a huge global presence and total sales now still well in excess of $20bn.

Part of the acquired energy is used to liberate the electron from its atomic binding, and the rest contributes to the electron's kinetic energy as a free particle. While free electrons can absorb any energy when irradiated as long as this is followed by an immediate re-emission, like in the Compton effect, in quantum systems all of the energy from one photon is absorbed-if the process is allowed by quantum mechanics-or none at all. Moreover, the energy of the emitted electrons will not depend on the intensity of the incoming light of a given frequency, but only on the energy of the individual photons. Since an increase in the intensity of low-frequency light will only increase the number of low-energy photons, this change in intensity will not create any single photon with enough energy to dislodge an electron. ![]() If the photon energy is too low, the electron is unable to escape the material. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. Other phenomena where light affects the movement of electric charges include the photoconductive effect, the photovoltaic effect, and the photoelectrochemical effect. Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave–particle duality. In extreme cases, emissions are induced with photons approaching zero energy, like in systems with negative electron affinity and the emission from excited states, or a few hundred keV photons for core electrons in elements with a high atomic number. Įmission of conduction electrons from typical metals requires a few electron-volt (eV) light quanta, corresponding to short-wavelength visible or ultraviolet light. Because a low-frequency beam at a high intensity does not build up the energy required to produce photoelectrons, as would be the case if light's energy accumulated over time from a continuous wave, Albert Einstein proposed that a beam of light is not a wave propagating through space, but a swarm of discrete energy packets, known as photons-term coined by Gilbert N. ![]() The experimental results instead show that electrons are dislodged only when the light exceeds a certain frequency-regardless of the light's intensity or duration of exposure. An alteration in the intensity of light would theoretically change the kinetic energy of the emitted electrons, with sufficiently dim light resulting in a delayed emission. The experimental results disagree with classical electromagnetism, which predicts that continuous light waves transfer energy to electrons, which would then be emitted when they accumulate enough energy. ![]() The effect has found use in electronic devices specialized for light detection and precisely timed electron emission. The phenomenon is studied in condensed matter physics, solid state, and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. Electrons emitted in this manner are called photoelectrons. The photoelectric effect is the emission of electrons from a material caused by electromagnetic radiation ( light). Photoemission of electrons from a metal plate accompanied by the absorption of light quanta – photons ![]() Not to be confused with Photovoltaic effect. |
