Airport utility 6.x3/30/2023 ![]() Questions? Comments? Have a fix? Post them below or e-mail us!īe sure to check us out on Twitter and the CNET Mac forums. AirPort Utility's new interface is intuitive and useful for basic setups, but its advanced features lack a number of settings or have poor interface layouts for configuring them. It may be that the new utility just has not adopted these features yet, and they may appear in future releases, but for now despite its more pleasant layout, the tool has some significant drawbacks. Luckily Apple issued both version 5.6 and version 6.0 of its AirPort Utility at the same time, so people with needs for the missing features should still be able to configure them with the older utility. ![]() In addition to those that Joshua found, Richard Gaywood from The Unofficial Apple Weblog (TUAW) recently wrote a summary of the missing features he found, including many of those that Joshua noted here but adding a few others such as no wide-channels options, and missing LDAP settings, in addition to some relatively inadequate settings such as the port-mapping list only showing a couple of lines.Īs both Joshua and Richard describe, many of these options are esoteric and most will not cause much difference to home users however, if you are an IT professional or someone who enjoys fine-tuning or adjusting network properties, then you may find the new AirPort Utility somewhat lacking or frustrating to deal with. Joshua has a first-generation Time Capsule and noted the following options from prior versions of AirPort Utility are now missing in the latest version: AirPort Utility's new interface is intuitive and useful for basic setups, but its advanced features lack a number of settings or have poor interface layouts for configuring them.

![]() ![]() And if they are in their active quasar phase, you’ll be blasted by high-energy radiation. If you get too close, the enormous gravity will suck you in. Massive black holes are dangerous in two ways. These black holes are dark most of the time, but when their gravity pulls in nearby stars and gas, they flare into intense activity and pump out a huge amount of radiation. The remaining central ball is extremely dense, and if it's especially dense, you get a black hole.Now, if a person found an isolated supermassive black hole suitable for scientific study and decided to venture in, everything observed or measured of the black hole interior would be confined within the black hole's event horizon. It expands and contracts until one final collapse, causing part of the star to collapse inward thanks to gravity, and the rest of the star to explode outwards The shrykes and goblins meet up in the sewers and, being mortal enemies, begin to attack each other. To enter one safely, you would need to find a supermassive black hole that is completely isolated and not feeding on surrounding material, gas, or even stars.When this happens, gravity pulls the centre of the star inwards quickly, and collapses into a tiny ball.This happens when stars run out of fuel – like hydrogen – to burn, causing the star to collapse.Most black holes are made when a supergiant star dies.Conventional laws of physics stop applying at this point.At the singularity, space-time curves infinitely and the gravitational pull is infinitely strong.It's a one-dimensional point that contains an incredibly large mass in an infinitely small space. ![]()

Injustice 3 confirmed3/30/2023 ![]() ![]() Speaking on the Giant Bomb podcast, Grubb suggested that the ongoing uncertainty surrounding Warner Brothers Games, and the Merger with Discovery, led to NetherRealm changing projects or potentially abandoning any hope of working on an Injustice 3 project. However, according to VentureBeat reporter Jeff Grubb that could be about to change. As we’ve touched on before, that’s partly to do with NetherRealm’s pattern of flipping between each series. NetherRealm has refused to comment on the post, so we’ll just have to wait for an announcement from the studio.Ģ1 August 2021 – Many fans would rightly have assumed that the next project after Mortal Kombat 11 would be a new entry in the Injustice series. We certainly know how much Ed Boon loves to tease fans. Some fans believe this might have been a deliberate leak. Those fans willing to enhance the image further will also spot part of an email that reads “our fans eagerly scrape the internet for any trace … Take extra care with this material.” Eagle-eyed fans spotted that on his monitor was a file named MK12_Mast. All the most recent updates are found just below.Ģ8 January 2022 – Jonathan Andersen, a NetherRealm senior production manager may have revealed a big clue that the studio’s next game could be Mortal Kombat 12.Īndersen tweeted the image below before scrubbing it 10 minutes later. 14 September Update - Checked for the latest Injustice 3 news. It might even be a Marvel fighting game, which has been rumoured to also be on the cards and when you look at the rate of Studio’s currently working with Marvel Games on new titles, it wouldn’t be the craziest idea right now.įor now, we’ll assume Injustice 3 is up next and if you’re keen to know more about the potential project, we’ve got everything you need to know in one place, so keep reading. Whilst we do know that NeatherRealm Studios have been working on a new project since July 2021 – when the dev announced they were ending support for Mortal Kombat 11 – it’s still not entirely clear what this “next project” is. It goes without saying that there’s clearly an appetite for another entry in the Warner Bros DC Comics brawler, and there are certainly a lot of storylines yet to be resolved from the end of Injustice 2. ![]() Will NetherRealm Studios make Injustice 3? This is arguably one of the big questions currently being asked by the fighting game community right now, with many fans unsure on the state of the game in the midst of the Warner Bros Discovery merger. ![]()

Tivoli itrace3/30/2023 ![]() When the site was no longer used as a sanctuary, its riverside location attracted various industries: woolen mills, an arms factory, hydro-electric plant, and paper mill.Īfter extensive excavation and restoration, the Sanctuary was opened to the public in 2015, with an Antiquarium established at the former paper mill. The sanctuary, which housed the statue of Hercules, was designed to impress visitors arriving from Rome, with its foundations rising 50 meters above the river. The complex was built over an ancient road, which later became the via Tiburtina that was carried beneath the buildings through a tunnel, called the Via Tecta (covered street). ![]() A theater was built into the naturally sloping ground aligned with it was the temple, around which was a large plaza surrounded by porticoes. ![]() Begun in the second century BC beside the Aniene River, the sanctuary was in three parts, covering about 3,000 square meters. You'll find mosaics, baths, a nymphaeum, fountains, colonnades, statues, and the Maritime Theater-a pool with an island where Hadrian escaped the pressures of government.Ī three-minute walk from the Villa d'Este, the imposing Sanctuary of Hercules Victor is an outstanding example of Roman cult buildings from the era of the Republic. In inscribing it as a World Heritage Site, UNESCO described it as combining "the best elements of the architectural heritage of Egypt, Greece, and Rome in the form of an "ideal city." Today, most of this open-air museum of the finest second-century architecture lies in ruin, but in such a scenic, green setting that it seems more like a romantic garden than an archaeological site.Ī few buildings have been repaired or reconstructed, but to appreciate what the complex looked like, begin by seeing the model near the entrance, then explore the grounds and the remains of the imperial palace. He had some of the finest Greek sculptures reproduced, and many of these are in Rome today, long after the Greek originals have disappeared. Hadrian tried to reproduce here in full size some of the places and great buildings he had seen in his travels, especially those of Greece and Egypt. The magnificent complex of buildings and gardens, built in the second century AD by the widely traveled Roman Emperor Hadrian, covers an area of 120 hectares. Villa Adriana (Hadrian's Villa) Villa Adriana (Hadrian's Villa) Among the garden's highlights are the elaborate Fontana dell'Organo, with its water-powered organ the Cento Fountain, a long row of fountains in a stone wall Fontana dell'Ovato, with its cool walkway behind a waterfall Fontana del Nettuno and the Gran Loggia, where the cardinal and his guests dined overlooking the gardens.Ģ.

Using different lenses with iconographer3/30/2023 ![]() ![]() It’s also the most versatile option by far. What is a Wide-Angle Lens?Ī post shared by PhotosWithPhones lenses are ideal for legendary landscapes, capturing cityscapes, and certain kinds of portrait photographyĪre you looking to fit more into your photos while being able to shoot almost anything Whether you want to shoot massive landscapes or a cramped and cluttered corner office with immaculate clarity, a wide-angle lens is for you. In each section, there will be a discussion of the best subjects for each mobile photography lens. So, the vital thing to understand is how the clip-on lens affects what these manual settings create in the digital file.Įach lens is perfect for specific situations and less than ideal for others, so keep in mind what you like to shoot while reading. With your smartphone, the same mechanics are happening, just digitally. There is a manual setting within a camera that adjusts how much light is let in, how much the sensor opens, and for how long the sensor remains open, among other things. When you press the button to take a photo on your DSLR, a sensor opens to allow light into the camera. This way, you’ll better understand the benefits of adding additional clip-on lenses to your arsenal. These lenses, as one might guess, are ideal for shooting still photos.īefore we get into what each cell phone camera lens does, perhaps it’s best to understand ‘the how’ behind the process of taking a photo and how each different lens affects the process. If, on the other hand, you’re a mobile cinematographer, we’ve covered smartphone videography tips, tricks, and gear too. If you’re looking to purchase some of the top clip-on lenses for cell phone photography, we’ve broken them down before in a more thorough list. For example, it’s ok to mount your Wide-Angle lens onto an Ultra-Wide Camera – they’re both designed to capture landscapes! Do note, though, that one benefit of your cell phone coming with five cameras is that you can experiment with the other pairings too. The jist of how to pair a mounted phone camera lens with the lenses on your phone is this – pair lenses and cameras together that are designed to do similar things. S0, both Apple and Moment have a Wide option, but what’s similar and what’s different about the offerings? How do they react together? Do you need one if you have the other? The above video does a great job of providing visuals that show this. ![]() When it comes to developing an understanding of the basics of the cell phone camera lenses, it’s crucial to know the difference between lenses produced standard for a phone versus those added through a third-party, like Moment. ![]() Sandmarc Lens Review - Are these the best lens for smartphone photography? Types of Smartphone Camera Lenses – What Comes Standard versus Add-On Lenses And, even more importantly, why that lens is so crucial. Remember, you need to know what to buy based on your mobile photography style. ![]() You can then evaluate their work and see if it works for you. So, your best option for answering the questions above is finding a content creator using your exact set-up. Well, there are lots of different kinds of lenses, and each seemingly serves a very different purpose. Think about it, if you add a Moment Wide lens to a Wide camera on an iPhone 12 Pro, then does the scene become exponentially wider? Will there be any sort of distortion from the widening? How will the lenses complement each other? Once you add clip-on lenses to the mix, things get more confusing. Do you even know which of your mobile phone’s camera lenses is best suited for: From focal length to the field of view, if you don’t have an intimate knowledge of photography gear, then buying a smartphone with photography in mind is tough. In 2020, some cell phones come standard with five cameras featuring 100+ megapixels, so a comprehensive study of both smartphone standard and add-on lenses is more important now than ever.īut, there’s too much technical jargon in the majority of explanations of the types of mobile phone camera lenses. Understanding the capabilities and nuances of your smartphone camera lenses can be tough, but it’s necessary for growth as a mobile photographer. ![]()

Water particles3/30/2023 ![]() ![]() Water molecules form hydrogen bonds with each other and are strongly polar. It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide). It is the most abundant substance on the surface of Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". Water ( H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. Partially miscible with diethyl ether, methyl ethyl ketone, dichloromethane, ethyl acetate, bromine.ģ.1690 kilopascals or 0.031276 atm at 25 ☌ Miscible with methanol, ethanol, propanol, isopropanol, acetone, glycerol, 1,4-dioxane, tetrahydrofuran, sulfolane, acetaldehyde, dimethylformamide, dimethoxyethane, dimethyl sulfoxide, acetonitrile. Improved solubility in carboxylates, alcohols, ketones, amines. Poorly soluble in haloalkanes, aliphatic and aromatic hydrocarbons, ethers. Salty water has different characteristics.Almost colorless or white crystalline solid, almost colorless liquid, with a hint of blue, colorless gas Freshwater has its greatest density at four degrees, and sinks to the bottom. Ice is less dense and floats on the surface. It thus behaves differently from other substances in many ways. ![]() It is replaced by water flowing in at the sea surface.ġ.7 > The water molecule is asymmetrical and is therefore oppositely charged at its two ends. This density trait is the engine for convection, one of the most important elements of the climate system cold, salty water is heavy and sinks to great depths. So surface cooling can cause convection until ice is formed. This is, in fact, minus 1.9 degrees Celsius. At this salinity water has a greatest density of minus 3.8 degrees Celsius, which is below the freezing point of seawater with average salinity. The average salinity of the ocean is 34.7 parts per thousand (‰). As a result, it approximately doubles the warming originally caused by carbon dioxide.Īnother important property of water is its ability to dissolve salts, which significantly changes its density. Because of its dipole molecule, water absorbs infrared radiation very efficiently. For example, if the temperature rises as a result of higher carbon dioxide levels, then the water vapour content also increases because the warmer atmosphere can sustainably hold more water vapour. In addition, it amplifies the impact of other substances on climate. H 2O in the form of water vapour in the atmosphere has a decisive impact on the heat budget of the Earth water vapour alone is responsible for about two thirds of the natural greenhouse effect. Water influences climate not only in its liquid and solid states. The inertia of climate is a result of the high heat capacity of water in the first place. If the water molecule were symmetrical (not a dipole), then water (ice) would melt at minus 110 degrees Celsius and boil at minus 80 degrees. Both, the freezing and boiling points of water (zero and 100 degrees Celsius, respectively), so much a part of our daily lives, are really rather unusual. This means that water can absorb large amounts of heat before it boils. In fact, water has the highest heat capacity of all liquid and solid substances with the exception of ammonia. Because the water dipoles tend to hold together like small magnets, water reacts sluggishly to warming or cooling. The dipole character of water is a critical factor for climate. This produces a dipole, a molecule with one negatively and one positively charged end.ĭepending on the temperature, these dipoles align themselves into aggregates according to their charge, for example, in the formation of an ice crystal. Its oxygen atom (O) and the two hydrogen atoms (H) are asymmetrically arranged. The reason for this anomaly lies in the unusual properties of the water molecule (H 2O). This is seen in the large ocean regions at polar latitudes, which are partly covered by ice. Ice is lighter and floats at the surface. This phenomenon is referred to as the water anomaly. But surprisingly, to reach the solid ice phase, the water molecules again move farther apart. Many freshwater lakes have a temperature of four degrees at their deepest point because the heavy water sinks to the bottom. Water, however, attains its greatest density at four degrees Celsius because the water molecules are packed closest together at this temperature. In almost all substances the atoms and molecules move closer together as they get colder. Water behaves differently from most other chemical compounds. ![]() |
