How to Disinfect your Gadgets

Did you know that your technology products that are at home are filled with germs? At a time when telework is being promoted, do you have a good practice when cleaning and disinfecting your techno products? It is important to regularly disinfect your technology, especially during cold and flu season. While some of you may do so once a week, it is recommended that you do it every day after a long day’s work.

Even if you’re the only ones using your computer, your smartphone goes with you everywhere. In order to avoid any risk of contracting certain bacteria, it is better to be vigilant and pamper our technology with a good daily cleaning. Here are some tips for properly disinfecting your laptops, tablets, iPads and other technology products.

How to clean and disinfect electronic devices

Right now, I’m sure you wash your hands every time you touch your face or scratch your nose. In this pandemic, we know the importance of keeping our distance, washing our hands frequently and even cleaning our groceries.

But have you thought about what happens when you scratch your mouth and then use the family computer or tablet? We are all at home for work, you may even share the office working with your children, your spouse, it is better to make sure that everything is disinfected.

What to do before cleaning

First of all, it is very important when you are considering cleaning the electronic components, first validating your manufacturer’s instructions, because the use of certain products is not advisable. If your device is damaged at any given time, failure to follow the manufacturer’s instructions may result in the cancellation of any warranty you may have.

Never spray anything directly on the device. Spray a disinfectant solution on a microfiber cloth first, then wipe the device with the cloth. Do not use paper towels instead of a microfiber cloth, as you may cause scratches.

Do not use chemical cleaners on any device’s screen, as this can damage the screen (including disinfectant wipes). Screens should be cleaned with electronic wipes or a screen cleaner such as Insignia’s Monitor Cleaner Wipes.

Wash your hands or use hand sanitizer before and after using your device, especially when the device is shared with other people.

It’s time to clean up your techno products

My smart phone is everywhere with me. I’m sure you go to the grocery store with your smartphone, to the park, to the restaurant and even to your friends. Phones can hold about 25,000 harmful germs and bacteria per square inch and we constantly touch them and hold them against our faces. It is important to remember that, like our hands, our gadgets can pick up and redistribute germs and it is important to disinfect them to prevent their spread.

In order to disinfect and sterilize your smartphone, I discovered the 9W High Efficiency UV Sterilization. In fact, all your small techno products can be sterilized to 99.9% of bacteria and germs

with UV light. I believe when this moment, we should all have this product at home. Wireless headphones, masks, physical activity monitors, keys, in short, anything that can get into this box will be cleaned.

This box does not use any liquids, heat or chemicals which makes it use very safe. Ultraviolet light can affect microorganisms hidden in space that even wipes cannot clean.

You find this UV box interesting, but you’d also like to be able to enter your computer keyboard? I have a really perfect solution for your game controllers, your console, your computer mouse and even more, here’s Tzumi’s ION Sanitation Wand.

Just like the previous product, this wand uses UV-C light to sort 99.9% of germs to disinfect anything you touch during the day. Right now, I think it’s the product to have at home. When you finish your day at your workstation, all you have to do is scan the technological elements you have with UV light. If you have to lend or share the same tablet with the whole family, you can quickly eliminate germs and bacteria in 30 seconds.

Even if you think you never touch your computer screen, know that if you have a cold your screen can become a source of germs. Get into good habits and clean your computer and laptop screens for a clear view and fewer germs.

To avoid damage or violent shock, you need to turn your screen off. Gently wipe the monitor without traces or dust with a microfiber cloth. If this doesn’t work, you can use a diluted dish soap solution, according to CNET. You will only need one drop of soap and the water should be lukewarm. Dip a clean microfiber cloth into the solution and wring it out carefully.

Then gently wipe your screen with the damp cloth. Rinse all the soap out of this cloth and wring it out again. Return to your screen to remove any soap residue. Once again, gently wipe your screen, this time with a dry microfiber cloth.

For your keyboard, if you’re like me, you happen to snack or have lunch at the computer these days, which can lead to pretty dirty keyboards. I personally have to clean mine every day because it is filled with the hair of my 2 cats.

Spray the keyboard with compressed air to remove leftover crumbs or dust with a vaporizer. Lightly dab a cotton swab in soft-friction alcohol. Stamp each key with a slight circular motion. Dry the keyboard keys with a microfiber cloth.

We are all adjusting to our new lifestyle. This involves more methods and best practices related to hygiene, cleaning and distance. As we work more and more with technology products, it is important to understand that they are a living source of germs and bacteria.

Keeping your computers, laptops and mobile devices cleaned can go a long way to reducing the amount of germs that spread in your home. However, you may need to be even more vigilant during critical cold periods such as winter and spring.…

What Is 3D Rendering And How Does It Work?

3D rendering basically consists of the process of creating two-dimensional images (for example, for a computer screen) from a 3D model. These images are generated based on data sets that dictate what color, texture, and material a given object has in the image.

How Does It Work

In principle, 3D rendering is similar to photography. For example, a 3D rendering program directs a camera towards an object to compose a photograph. Therefore, digital lighting is important to create a detailed and realistic rendering.

Over time, various rendering techniques have been developed. However, the goal of any 3D rendering is to capture an image based on how light affects objects, as well as real life

One of the first rendering methods was rasterization, which treats models as a polygon mesh. These polygons consist of vertices, which contain information such as position, texture, and color. Subsequently, these vertices are projected in a plane normal to the perspective (that is, the camera).

The vertices act as limits so that the rest of the pixels are filled with the appropriate colors. Imagine painting an image by first arranging an outline for each of the colors you are going to paint: that’s what rendering by rasterization consists of.

A rasterization is a quick form of rendering. Today, this technique is still widely used, especially for real-time 3D rendering (for example, in computer games, simulations, and interactive graphic interfaces). More recently, the process has been improved by increasing the resolution and by using the anti-aliasing or anti-lapping functionality, which makes it possible to soften the edges of objects and blur them with the surrounding pixels.

Although the rasterization technique is effective, it raises certain problems in the presence of overlapping objects: if the surfaces overlap, the last one that has been drawn will be reflected in the 3D rendering, causing the wrong object to be rendered. To solve this difficulty, the “Z-buffer” concept in rasterization was developed, which consists of a depth sensor that indicates which surfaces are above or below a certain point of view. This method was no longer necessary, however, when ray casting was developed.

The rays extend to each pixel in the image plane. The surface on which they strike first will be shown in the rendering, and any other intersection after this first surface will not be rendered.

In essence, the primary rays from the camera point of view are projected onto the models and generate secondary rays. Once they reach the model, they produce rays of shadows, reflections and refractions, depending on the properties of the surface. A shadow is produced on another surface if the path of the shadow ray towards the origin of the light is hindered by the surface.

If the surface is reflective, it will project the resulting reflection beam at a certain angle and illuminate any other surface with which it hits, which will generate a new set of rays.…

GPUs as Past, Present, and Future of Computing

We all use our computer, but many times we are not aware of the technology in them. Incredible machines that allow us to enjoy leisure with graphics videogames very close to reality, physics mechanisms that emulate destroyed skyscrapers or blows between two vehicles fighting in frantic races. For these tasks, the work of the graphic processor or GPU is essential.

Today we will enter the world of graphics cards, GPU architectures, and their differences with another processor, the central or CPU, much better known because graphics cards are essential in today’s computing and are a basic part of what is important for many in the future: GPU, or data processing using GPU. Today we enter fully into this topic with our special graphics processors.

The pre-GPU era

Things have changed a lot since home computers began to be implanted in our homes back in the 80s. The hardware is based on the same foundations of von Neumann architecture, although it has evolved in a very remarkable way, and the Current systems are now much more complex.

The trio of components raised by John von Neumann was three: ALU, memory, and input/output referring to mechanisms that process, store, and receive/send information, respectively. Interpreting the architecture on a current computer would be equivalent to having only one processor, one disk, one keyboard, and one screen. Obviously, a modern system is made up of many more elements, and among them, the graphics card has become one of the current fundamental components.

The Origins

In the first computers, the central processor – CPU, central processing unit – was responsible for managing and processing all kinds of information.

Although those first systems used text-based interfaces, with the arrival of the first graphic interfaces, the level of demand grew not only in the operating system itself but also in many of the applications that began to emerge at the time. CAD programs or video games, for example, required many more resources to function properly.

At this point, system designers relied on a component that already existed to evolve it and make it grow. The math coprocessor or FPU – floating-point unit – was used in many systems to speed up data processing. They can be understood as a second processor, although some of the differences with respect to the CPUs are very clear: they cannot have access to the data directly (it must be the CPU that manages this section), or they execute a much simpler set of instructions to process floating-point data.

The definition of the general-purpose processor we had already used before. These types of processors are the most common, and the CPU is the most common example. They use generic records and instruction sets that can make the most diverse operations. An important fact for the topic that we are going to deal with is that the CPUs did not operate directly with floating-point data, but that they performed a previous conversion that involved an expense in resources and, therefore, time. Therefore, mathematical coprocessors were important as they could process this type of data.

The demands continued to grow, and the systems of the time had a CPU and an optional FPU that ended up becoming fundamental: the mathematical coprocessors evolved towards the GPUs, being the most efficient component when processing and determining the graphic aspect of everything type of software.

The First Graphics Cards

Mathematical coprocessors continued to evolve and improve and began to mount on individual cards. Through this format, they could have more space to create larger chips, with more transistors and circuitry and better energy connections, which were able to offer greater process capacity.

It was not until 1999 when NVidia coined the term GPU, Graphics Processing Unit, to replace the previous video cards. After a successful RIVA TNT2, they presented the NVidia GeForce 256, and to promote it, and they placed great emphasis on the graphic possibilities that it brought to our team. Video games, gaining more and more followers, were one of the keys for GPU designers to increase their performance year after year.
