                                              How it Works: A Look at Popular Power Tools

                                              If you have no knowledge of power tools then it can seem overwhelming trying to figure out what they’re all used for and how to use them. There are many reasons to learn about power tools, for example, you may be wanting to purchase one as a gift, this can be difficult when you have limited basic knowledge. You may also want to get into doing light DIY yourself and not have a clue where to start or you may just be intrigued by how power tools work as their such great pieces of tech. We’ve found the most popular power tools there are and we’ve figured out how it is that they work, keep reading if you want to know too. 


                                              Power Drill

                                              This is probably the most recognizable power tool, it is used for drilling holes into various surfaces, like metal, plastic, wood, or stone. These different surfaces will have slightly different requirements and need to use different types of drills. How these great tools work is that the drill has a clamp at the end of it which keeps whatever you’re trying to drill in the correct place, this is called a chuck. If you need to loosen or tighten this there is something that comes with your drill called a chuck key which will allow you to do this. The drill then has a motor inside which turns and forces the drill to make a hole in the material. 



                                               For many tasks that require sanding, it will be fine to just use sanding blocks or extra fine sandpaper to smooth surfaces but in some situations, you will need to use a much more powerful electric sander, this is usually for things like repairing furniture. Electrical sanders work in a similar way to normal sanding blocks but take the work out for you. With a sanding block you rub a surface to smooth it, electrical sanders do this with much more force and in a variety of patterns so that the results are much better. 



                                              This is another popular power tool as it is super handy to have and use, they can be used on all sorts of materials including wood, metal, and plastic. The blades that come with a jigsaw tend to be very thin which allows them to cut out more difficult shapes like circles. The jigsaw is simple, the blade is simply attached to the device and you can position it wherever you need to make a cut. They also tend to have variable speeds which if you’re nervous you should use the lower speed to avoid mistakes. Whilst this is a great tool it isn’t great for any thicker materials as the blade is so thin it often will bend rather than cutting. 


                                              Angle Grinder

                                              Angle grinders have 2 purposes they can cut the thicker materials that a jigsaw is not strong enough to and they can also grind materials like metal and tiles. The main part of this tool is the disk, this disk is what performs the cuts when it is spun at a high enough speed, there is an engine inside the handle of the tool that causes the disk to spin, and usually, you can choose out of several speeds. These disks come in different materials; the standard material is a metal disk but if you’re trying to cut tougher materials like a stone then you may need to use a diamond disk. They also come in a variety of sizes to suit any need, the most commonly used size is disks with a 4” diameter.  

                                              The Technician’s Guide to Running VPS Server Repair

                                              As technology has become more advanced there is more stuff to understand and keep up with than ever before. For the average person, there are too many developments to stay on top of as well as working, socializing, eating and sleeping. The developments happen too quickly and there are just not enough hours in the day for people to manage to keep completely up to date with tech-related procedures. The best piece of advice that we ever got from a technician was that if you’re commonly running into problems with your VPS serve then the best thing to do is to swap to a new one as the right vps server will make all the difference, they are designed well and whilst problems may occur, it shouldn’t happen often. If you only occasionally have problems then we’ve made a helpful summarised guide of everything VPS that you need to know.

                                              What is a VPS server?

                                              The technicians we spoke to had to explain everything, even the very basics so this was the first question that they answered. So, if you, like us, didn’t even know what VPS stands for, it stands for Virtual Private Server. A serve is something within a computer, they usually have a lot of power as the purpose of a server is to store a large quantity of data and information to make up something such as a website. When you search for a website, their server will boot up that computer and allow you to see whatever website you searched for on your screen. The private part is pretty straightforward as that means only you can access the server and for the virtual part, this is simply splitting that massive amount of information up into multiple more manageable servers.

                                              How does a VPS server work?

                                              Now we all know what a VPS server is, the next thing to understand is how a VPS server actually works. The answers we were given to this by technicians were quite technical so we’ve tried to keep it as simple as possible. A VPS server is at its most basic, a server that is running within another server, so the main server you will still be sharing with many other users, but the VPS within this will be private and only accessible by you. Your VPS is like a compartment within the bigger server that is surrounded by virtual walls, this is what stops anyone else from being able to access it. This keeps absolutely everything separate from other users, from memory to disk space and everything else in between.

                                              Why should I use a VPS?

                                              We were given a long list of reasons why people should switch to using a VPS so we’ve summed up the most important ones. If you’re worried about security then a VPS is the perfect solution, it will have many enhanced security features, makes websites much more reliable, and makes things like online payments much more secure. Another main reason is that if you’re running a website and it is becoming more popular, you don’t want it to start crashing or going slowly as this will lose lots of the traffic directed to your site, by switching to a VPS you’ll be much more suited to deal with high volumes of traffic problem-free. Other reasons included if your website is already running slow if you have an online shop if your budget is tight or if you’re frequently running into server errors.

                                              What problems may occur that I need to repair?

                                              There can be a wide range of issues with a VPS server, but overall they still seemed like they were much better to use than a regular server. Some of the most common problems that people run into with VPS servers are security issues, although there are enhanced security measures there can still be security-related issues, for example, if a website receives abuses, this can affect the entire server and cause the whole server to shut down. This kind of problem is usually caused by a customer, a technical issue, or by a hacker purposely trying to shut down your server. The other main issues that occur related to the actual server itself, sometimes if a server is not as reliable as you may have thought it was going to be, then the hardware may not be adequate for the task it’s performing, sometimes this happens if the server provider is overselling their resources.

                                              How do I run a VPS repair?

                                              Although problems don’t commonly occur, it’s important to know how to identify and fix them in case they do. To highlight and resolve any issues you need to run a VPS repair which is much easier than it may seem. You need to make sure that your server is in rescue mode, this temporarily changes your VPS into an operating system so you can deal with any issues. You should be able to find the rescue mode in your menu section of your VPS. All you have to do is select to boot this mode up and then this function will do all the work for you. There will be a progress bar whilst you wait and when this reaches 100% it will tell you of any issues and provide the best advice on how to deal with them.

                                              Movie Editing: 4 New Techniques You Should Use

                                              Picture the quick-cut transitions and comedic editing style of any Edgar Wright movie (the work of the editor, the flash-bulb cuts and freeze frames of Martin Scorcese films, or the frantic and fabulous opening scene in City of God. These are all different types of edits and cuts that one can make when putting together a story. A good example of the importance of editing is YouTube content. To bring in views there are a number of things you need to do. You can use a shortcut to gain views, and for buying more views on youtube you can go here to find out how. But without this method, your video quality needs to be top-notch. So let’s break down the different editing techniques you could use.


                                              Non-linear Editors

                                              Before the digital era, video editing was done with videotape decks linked together. Editors would use the source deck to play the segments of video they wanted to edit into the program while using the record deck to record the clips into the master program.  Thus, editing had to be done in sequential, or linear, order. A non-linear editor like VEGAS Pro allows you to work on your program in any order you want, compiling the final program when you’re finished. Non-linear editors are non-destructive; they do not change your media files.  Whatever you do while editing – cuts, effects, color grading, etc. — is saved to the project file, not to your media files.  When you export your edited video, the NLE creates entirely new video files, leaving the original files alone.



                                              A jump cut is when a single shot is broken with a cut that makes the subject appear to jump instantly forward in time. Whereas most editing techniques are designed to “hide” the edit, a jump cut is a stylistic choice that makes the edit completely visible. Some filmmakers believe jump cuts are inherently bad because they call attention to the constructed and edited nature of the film. They are seen as a violation of typical continuity editing, which seeks to give a seamless appearance of time and space to the story. A jump cut differs from a match cut in that the latter aims to create a seamless transition between two separate scenes. The usual goal of a match cut is to draw a metaphorical comparison between two different objects, subjects, or settings.


                                              Rough Cut

                                              Assembling a rough cut is a key step in the Post-Production timeline for a film. A rough cut in the film is far from the only type of rough-cut. Rough cuts are also key to film-adjacent professions as well such as in the television and advertising industries. Directors, editors, assistant editors, VTR operators, and producers can all be involved with rough cuts, so anyone interested in these filmmaking roles will end up working hands-on with a rough cut eventually. Technically speaking, the first edited version of a film is the “assembly cut.” You could say that the assembly cut is the first iteration of the rough cut, or that the rough cut follows the assembly cut as its own phase.


                                              Colour Correction

                                              Colour correction refers to adjusting white and black levels, exposure, contrast, and white balance to give you an image with accurate, unprocessed-seeming colors. The point of color correction is to ensure that subsequent color adjustments have more precision, and do not yield unintended results.

                                              The other purpose of color correction is to create visual consistency for your footage and scenes. You want them to match for better flow.

                                              How Digital Art is Made and Why Its so Powerful

                                              Art has been a staple of our society since our earliest ancestors painted on their cave walls. And while you could debate that is a far stretch from the Mona Lisa or the Scream. But art is what you make of it. And to our ancestors, those crude drawings were as much art as the things we create today.

                                              As technology has developed, humans have found new ways to create art using that tech.  Once the radio was invented, we soon created soundscapes and radio plays. Television brought about TV shows and movies. Lasers lead to laser light shows. Humans have the ability to create art from anything.

                                              Now we are in the digital age, it makes sense we are creating digital art. But digital art itself is now evolving and changing. So today we want to examine how digital art is made. And why it is so powerful when compared to normal art.


                                              There are simple ways to create digital art. Anyone with a basic PC can open up MS Paint and create some art in seconds. But for more serious and dedicated artists, programmers soon create fantastical programs that allowed them to create wonderful works.

                                              The earliest forms of digital art were advanced drawings or paintings created on a computer. Using a tablet and digital pen to draw, an artist had access to whatever colors, shades, and editing techniques they needed. This type of art was widely employed by companies like the digital marketing agency Func Media or cooperate giants such as Coca-Cola. All of their logos and slogans are created digitally these days.

                                              Advance Art

                                              But then a new art revolution emerged. 3D Modelling. One of the greatest advancements in both art and technology. Computers now had the power to let users create whatever they wanted. And artists made fantastic use of this new power.

                                              Digital art has swiftly moved from the 2D planes into whole new realms. Gaming is the perfect example of this powerful new art. The ability to create fully realized worlds, populated with hyper-realistic people. It is beautiful. And on the more arty side, we are seeing digital artworks being hosted in museums. Beautiful and complex moving images and impossible shapes brought to life in ways traditional art simply couldn’t.

                                              The programs that allow this art to be created work by letting users create the shapes using pre-programmed rendering tools. They create an image and then animate it according to specific rules and customized physics engines.

                                              The Power of Digital Art

                                              So why is digital art so powerful. Why are more and more companies using digital art, especially 3D digital art, as opposed to more traditional designs?

                                              For starters, people are captivated by the extent technology can go to. Digital art is more than just art. It is a testament to how far our society has come. So when people look at this form of art, they unconsciously realize this and it has a profound effect on them.

                                              A more realistic reason it is so powerful is that there are fewer limits than with traditional art. Digital art can do anything from creating alien worlds to turning a person into a soda can. Companies can use this to create much more engaging and enthralling content.

                                              Another great advantage is companies can now create hyper-real demos of what their products will look like and how they will function. An example is SpaceX’s ability to render exactly what their mars colonies will look like. For the customer, this means they can try a product virtually before they make a purchase.

                                              Why Brisbane is at the Forefront of the Computing World

                                              Brisbane has proven itself to be advanced in technological development. One of the biggest draws for international students interested in studying in Australia is the quality of scientific research. Australia is among the top 10 spenders in the world for research and development. 2% of all scientific papers in the world come from Australia, putting the country at the forefront of new technology and innovations. More and more companies are moving to Brisbane each year because if your company needs IT support in Brisbane or needs access to advance tech systems, you are going to be spoilt for choice. These impressive accomplishments can prove to be beneficial for international students who choose to study in Brisbane.


                                              Technological advancements

                                              Australia is known for adopting new technologies at a faster rate than most other countries. It entered the new millennium with one of the highest rates of internet access in the world. Scientists and researchers from Australia have been responsible for many major breakthroughs and technological developments around the world. In fact, Australia boasts sixteen Nobel Prize recipients—not bad for a country with a population of about 24.6 million. The growth of technology in Australia has had several important results. It has increased opportunities for innovation and design, helped various industries make improvements in their already existing establishments, and helped to improve the quality of their goods.

                                              The technology growth has also helped to improve Australia’s economy, as it is now one of the leading countries in the world for importing and exporting goods. Australia has a tradition of world-class research and development, which has benefitted millions around the world, such as the discovery of acquired immunological tolerance in 1960, as well as observations that led to the discovery of the accelerating Universe in 2011. Australia prides itself on its commitment to scientific discovery and its ability to become so technologically advanced. Australia is in the midst of a major economic, social, and political transition, driven by global competition and technological transformation. Over the next 10 years, the pace of technological change will be highly disruptive to the workplace and this report examines the impact it will have on workers and the skills they need to thrive in the Australian economy.


                                              The future of technology

                                              Australia has a long and illustrious computing history. Trevor Pearcey’s Mark 1, also known as CSIRAC, was one of the first computers in the world. They have not stopped there. From the invention of Wi-Fi to quantum computing, they have continued to show their remarkable talent for innovation.  When you think of computers today, we may normally think of electronic digital devices. But the word ‘computer’ derives from ‘compute’, a word that entered the English language in the 17th century from the Latin computare – to come together or to settle an account. Before modern electronic machines, computers were people – mostly young women – hired to perform repetitive mathematical tasks by hand or with the aid of a mechanical calculator. When these functions started to be performed automatically by what we know as computer technology, the new field appropriated this term and human ‘computers’ became a thing of the past.


                                              How technologically advanced are they now

                                              Australia is still one of the highest technologically advanced countries in the world. Finland has taken top place as the most advanced. However, after Finland, other countries that featured at the top of the list were the USA, Sweden, Japan, South Korea, Australia, and the UK. The other European Union countries that were included in the top section, named ‘leaders’, were Germany, Ireland, Belgium, Austria, and France. Aside from their renowned computing technology, Australia is also well known for other innovations. Brisbane-based medical researchers Professor Ian Frazer and Dr. Jian Zhou developed the world’s first anti-cancer vaccine.

                                              Known by the commercial name, Gardasil, the vaccine protects women against four strains of a virus called human papillomavirus (HPV), known to cause three-quarters of all cervical cancers. As cervical cancer is the second-leading cause of cancer death in women, vaccination has huge implications for the prevention of cancer. Since 2008, the vaccine has been approved for use in more than 120 countries. Also an Australian creation, the purpose of the black box flight recorder is to record all the conversations of pilots and staff during crashes. These recordings then later can be used to find the reasons for the plane crash. The box is indestructible and helps investigators to get to the source of the problem. The black box flight recorder was invented by Australian scientist Dr. David Warren who lost his father to the plane crash.

                                              At first, the black box installation was made compulsory for Australian planes but now they are part of every plane. This has helped thousands of investigators discover the causes of many planes crashes that have taken place around the world. Furthermore, perhaps one of the most common inventions used is the ultrasound scanner. The ultrasound scanner uses echo technology of ultrasound waves for imaging of soft tissues of patients in real-time. This non-ionizing technique which can be damaging in some cases has allowed doctors to maneuver into patients ’ inside without side effects. This is one of the reasons why ultrasound is frequently used in prenatal care as it easily scans the progress of the fetus without any harmful radiations. It was developed and commercialized by Ausonius Australian Company. The ultrasound scanners have become one of the vital imaging devices in medicine because it is portable, gives access to real-time imaging and is non-invasive.

                                              How Does VR Gaming Work and Why is it so Expensive

                                              VR gaming dates back much further than most people would think, the first-ever VR headset was created back in 1968 by a computer science teacher, Ivan Sutherland, and one of his students, Bob Sproull. The first virtual reality headsets for consumers were released in the 1990s but really VR became available to the average individual in the 2010’s thanks to a field-wide effort to develop more advanced applications for VR.

                                              The first prototype in the 2010s was called the Oculus rift headset, this is what boosted the interest in VR development, in 2014 Facebook bought Oculus for $2billion and took over the development of the headset, it was following this purchase that Sony, Google, and Samsung all started developing VR technology too. VR became available for the general public to try in 2015, a VR roller coaster was launched, you could watch a VR experience of what it looks like inside the oval office and a VR experience showing what life is like in a Syrian refugee camp. These were breakthroughs in VR technology and in the years following this hundreds of companies started developing VR and the technology advanced rapidly bringing us to all the VR gaming we have today.

                                              VR gaming is extremely popular in 2021, but it’s not yet as popular as normal games such as the first-person shooter game Valorant, this is a popular first-person shooter game known for how difficult it is so you might have to use these cheats to win easily at valorant. Keep reading to find out how VR gaming actually works and why VR gaming is so expensive.


                                              The basics behind VR gaming technology.

                                              How VR works is all dependent on a headset that creates an immersive 3D environment that simulates your vision. The screen on the headset prevents you from seeing anything that is happening in the real world so you’re fully involved with what is on the screen, the screen is usually a mobile phone or connected to a device with an HDMI cable to create the environment. Most VR headsets require a minimum frame rate of 60 frames per second to make it seem realistic and there must also be a high refresh rate to keep up with people’s movements. If these two things aren’t high enough it will damage the user experience as there will be a lag between their movements and the actions on the screen. These two things also have to work in sync as if the frames per second are higher than the refresh rate it causes a distorted image which ruins the image for the user.


                                              Other elements of VR technology.

                                              Whilst image is the most important there are many other elements that have to be considered. The sound effects must be in complete sync with the image the users sees for VR gaming to be good; it’s also vital to have the right sounds to accompany the image the user is seeing as if happy music is playing during a horror game it will ruin the whole user experience. On top of sound, many advanced headsets also track any head and eye movements of the user to improve their experience further. This is done with laser pointers, mobile sensors, and led lights to detect movement. These are used as they have a very high accuracy which all adds to the consumer’s experience.


                                              Why VR gaming is so expensive.

                                              Any gamers will know that VR gaming is considerably more expensive than any gaming that has come before it, whether that’s PC, Xbox or Playstation, etc. VR gaming has always been expensive, before Facebook bought Oculus not many companies were interested in developing VR which meant there wasn’t much spending going into development initiatives. As the article previously explains, as the image is so important the headset needs high definition display and motion sensors, all of which are still expensive now and we’re even more expensive when the first headset was developed.

                                              Prices are starting to fall as more and more companies are developing VR which means the hardware is more frequently used causing a slight reduction in price. Creating the 3D environment is extremely costly, as well as creating tricks to guide the user through the game. On top of this, VR audio is developed in a different way to usually game audios which again is much more expensive. The reason that VR gaming is so expensive is that it is much newer than normal gaming, the more that it is developed and used the cheaper it will become. If you’re hoping to get on the VR gaming trend but can’t afford it just yet then you’ll be glad to know there is expected to be a $9billion expansion in the VR market, this should help to decrease the costs so you can finally get your perfect VR headset.
