The three-dimensional image of Princess Leia broadcasting her distress message is part of popular culture. Even those who have not seen the films of the saga, easily associate the holograms with Star Wars. If anything, holographic technology has a promising path ahead. The arrival of 5G will allow heavier images to be transmitted through networks. In this way, it will be easier for these 3D images to be adopted as a standard in communication between people.
Video calls, so common since the pandemic took over our routines, could be made using a 3D hologram. It’s not just the speed of the network that will influence our ability to deal with holograms. Also the low latency. These two aspects, of paramount importance in 5G, will allow images to be transmitted properly and not be unbalanced or suffer interruptions.
The origin of holography
The differences between holography and photography are obvious. The second captures a two-dimensional snapshot, while the first offers three-dimensional or multidimensional information. When the viewer moves they will see different angles of the projection and this will make sense at all times.
This result is reached through decades of research. One of the pioneers in this field was Dennis Gabor, who studied Mechanical Engineering at the Polytechnic University of Budapest and the University of Berlin. There he began to work in one of the physics laboratories of the Siemens company. Following Hitler’s rise to power, he was forced to leave Germany because of his Jewish origins. And it was in 1947, in the United Kingdom, when he happened upon a new method of forming images on a circular transparent slide. He called that technique holography, for ‘holos’ (everything, in Greek). Its discovery went unnoticed at first but years later it gained international recognition. So much so that in 1971, Gabor received the Nobel Prize in Physics.
How holograms work
It can be said that a hologram is a record of the interference that occurs between two beams of light when the light from one of the beams reflects off the object. This registration is carried out with a laser beam on a photosensitive film. From there, it is possible to generate a three-dimensional projection of the image.
When it comes to image projection, it’s really just a matter of having the right receiving device. “Holography works the same as live streaming, but changing the final screen for a holographic device”, point out from the technical department, specialized in holography. “Although it is always necessary to follow the specific technical parameters of lighting and recording.”
5G as a boost for holography
In the field of holographic images, 5G will be a boost. The graphics are very heavy, so the high speeds offered by the new generation of networks are adequate. But also its low latency, thus avoiding interruptions. Otherwise, the projections may suffer cuts and decompensation.
“Currently enough powerful network connections are needed to avoid delays in full HD broadcasts,” they point out from 3DH. “ With the arrival of 5G we hope to avoid these delays and to be able to broadcast in 4k without problems . It will help us a lot in the retransmission of holographic images ”.
There have been several pilots who have made video calls with holograms via 5G networks. And this is one of the applications being considered as a driver of the new connectivity. It is based on augmented reality. Two people could sit quietly chatting, each with the other’s hologram.
It seems like a thing of the future, but in 2017 the first international video call was already made. It was made between Seoul and New Jersey. In South Korea, KT Telecom, one of the participants in the project, pointed out that this type of communication would be available with the new 5G. The idea is to provide a greater sense of reality. From the flat image of video conferencing, it would move to a three-dimensional one, which would capture much more detail, such as body language.
The following year another milestone took place in the field of holography. Mischa Dohler, a professor of wireless communications at King’s College London and a music composer, demonstrated the capabilities of the technology at a concert. It was a live event, where he acted as a pianist on stage while his daughter sang through a hologram. The holography showed the girl a few meters from the piano, singing to the rhythm of her melody. The two were 1,000 kilometers apart, but the latency was minimal, so the result was impressive.
It’s just two glimpses of what holograms can do. From 3DH they list, as the main applications of technology, ” communications, events, exhibitions, fairs, shops, and businesses “. Although they point out that they are currently developing “new holographic applications for education, in schools, and the cultural sphere, for museums.”
Meetings via holographic telepresence
With current technology, it is possible to generate video calls with holograms. This is what the project offers a telepresence system that shows an assistant remotely through volumetric video. For this, augmented reality techniques will be used. Participants in this holographic meeting will have to wear HoloLens 2 type glasses.
The remote assistant will be staged in a 3D augmented reality figure. The idea is that it can be observed from all angles. A factor that will be useful for training in different areas, such as rehabilitation techniques or medical interventions. But objects can also be displayed in 3D, which will be useful when examining prototypes in industry, for example.
It will be necessary to deploy a volumetric capture room. This will feature multiple depth cameras, such as Intel’s RealSense. What they will do is capture the 3D figure of a person in real-time. From there, the images will be generated using Evercoast software. To send them, considerable bandwidth will be needed and here 5G comes into play. Thanks to edge computing processing, multidimensional images can be served to meeting attendees.
Video calls with a 3D hologram on mobile
The next step is to take the holograms to much more everyday terrain. This is what some initiatives that have put smartphones in the spotlight are looking for. From these devices, they have been able to generate holographic images, although not always with good resolution.
One of the methods used is simply an optical game to channel the light, with a simple pyramid projector. Of course, it is not the most advanced, but today almost all holograms generated with smartphones need some type of projector. Although some have tried to create them using only miniaturized technology, integrated into the smartphone, such as HoloFlex. For the moment, the results have to improve.
Beginners Steps to Land on a DevOps Engineer Profile
Considering the current IT market, the domain that looks like the best option for the IT folks’ career growth and salary is DevOps. DevOps is not a technology or a tool. Still, it is a culture, practice, or movement that emphasizes the communication and collaboration of both developers and operations teams while working on the automation of software infrastructure and delivery process. But the question that arises is what steps you must take to become a DevOps Engineer? Well, to answer it, the simple solution is DevOps Engineer Certification. But before that, let us dive into the process step-by-step and understand how you can practice DevOps effectively.
Organizations need people who are collaborative for adopting DevOps practices. They need people who are willing to change and are comfortable in adopting new technologies. Considering a tooling perspective, a good understanding of automation tools, systems, CI tools, networking, version control systems, and having experience in using various project management tools will help in paving the path for the adoption of DevOps.
The bitter fact is that you must understand that DevOps is not just for some systems or developers engineers. It is for anyone passionate about evolving technologies, practices, and willingness to work in a collaborative environment and work on automation to make everyone’s life better and easier. Here are a few steps that you can follow to land on a DevOps engineer profile:
Know the DevOps Culture
Before becoming a DevOps engineer, the first and foremost thing to do is understand the DevOps culture. DevOps is all about various teams working together to accomplish a common goal. We need DevOps to reduce the blame game in the company and establish a culture between different IT teams for better communication and hence better outcomes. Also, once you start practicing DevOps culture and understand it completely, you will realize that “Automation and CI/CD is DevOps” is a myth. With DevOps master certification, you can understand it better.
Learn the Unix System
We are living in an era where life without Linux or Unix systems is close to impossible. You should understand these systems better and know about various Linux distributions and their highly used workings (such as Ubuntu, RHEL, CoreOS, Centos, etc.). In the world of Unix, it’s all about terminal and less about GUI. So, start getting your hands dirty with the terminals of Unix systems.
Understand the Infrastructure and Working of Components
The primary building block of an organization is nothing but its infrastructure. It can either be on the on-premise data center or the cloud. Having an overview and understanding of the infrastructure components is a must for an individual aspiring to work in or practice in a DevOps environment. It will help gain a basic knowledge of networking, storage, single sign-on, load balancers, security, VPN, security, etc.
Get Cloud Certification
When it is about getting certification, don’t try to give the exam for the sake of a certificate, but do it only when you mean it. It will add significant value to your resume and will also help in boosting your knowledge. It won’t just be helpful for you but also for the organization to show that they have certified cloud engineers on board. You can pick one public cloud and gain knowledge of its core infrastructure services. To understand how it works in a better manner, do hands-on work on all the core services. You can get a DevOps Master certification, which can help you learn this better.
These days no servers are created manually. It’s all about automation, and automation has become a crucial aspect of every company. These days right from application configuration, to provisioning servers, to deployment, everything must be automated, and hence you must spread your arms across various DevOps tools that meet your requirement. For example – Vagrant, Minikube, Docker Desktop, Minishift, CLIs, Terraform, Packer, Saltstack, Ansible, Puppet, Chef, etc.
Distributed Systems, Containers, & Service Mesh
The adoption of containers is increasing as the days are passing by. It might be a case that the organization you are working in doesn’t work using containers now. But, it is always preferred to have hands-on knowledge of different container technology, for example, docker. It provides a competitive edge among others. On completing docker, you can also try orchestration tools and clustering like Docker Swarm, Kubernetes, etc. The platforms mentioned are best suited for architecture based on microservice.
Logging and Monitoring
The fundamental aspects of infrastructure are monitoring and logging. Almost all the apps deployed in the infrastructure produce metrics and logs. Depending on the design and architecture, records are stored in the logging infrastructure. All the companies will have a monitoring and logging infrastructure. The most widely used logging stacks are ELK and Splunk. There are also a few SaaS that provide the logging infrastructure, for example, Loggly.
You must also understand the best security practices. DevSecOps is another domain that works on integrating security practices in every stage of the DevOps. Especially in a cloud environment, the most common attack is crypto mining. Usually, this happens in an organization when they don’t maintain the cloud access secrets properly. This helps the hackers to get access to it easily.
Learn Scripting and Coding
To collaborate better, you need to understand the Developers’ world better. And for doing so, you need to understand the development process of an organization. So, understanding APIs, programming, etc., will help you collaborate better and troubleshoot things.
Having version control for everything you do is essential. It won’t take much of your time to learn, and also, it is crucial to understand the git operations anyway. You can take up some time to learn the tutorials available online. And, of course, Git is always the best version control tool you can ask for.
DevOps is a promising career path with a flourishing future growth. DevOps Engineer Course can help an individual in making a great start to their journey in DevOps.
3 Important Features to Look for in Employee Monitoring Software
Employee monitoring software keeps track of what your employees do during working hours. You may monitor staff productivity, manage billable hours, and even detect security concerns using the tool’s data. As a result of the epidemic, many companies have adopted a remote solution or even a 100 percent wireless staff model. As a result, many businesses are using remote employee monitoring software. The following are key characteristics to look for in employee monitoring software.
- User-Friendly Design
When it comes to handling apps and software, some individuals may be average. As a result, you should choose an easy-to-use employee tracking software. As a result, employees with non-technical backgrounds may use them with ease. That said, you are not required to compromise on the software’s robustness. Unfortunately, it isn’t easy to make a powerful piece of software easy to use. Most firms that give their rivals a run for their money strive to develop something useful to utilize. So, if you choose employee monitoring software from this perspective, you will save a lot of time that would otherwise be lost educating people on using it. Remember that the goal of an employee monitoring tool is to increase, not decrease, your workforce’s productivity.
- Geo-fencing Feature
When it comes to giving employees flexibility and comfort at work, the CEO of a firm should always tread carefully. After all, you can only control them to a limited amount. As a result, geofencing is a tool that gives employees more freedom while also boosting your company’s growth. In a nutshell, geofencing is a system that allows employees to clock in from several places at the same time. However, if they are not in one of the geofencing border areas, they are prohibited from doing so. Employees of some companies, for example, are permitted to work from home or the office. However, they can’t use geofencing to clock in if they aren’t at their office hour at either of the two locations. Also, suppose one of your workers cannot attend the office regularly or work from a remote location such as a restaurant. In that case, that location may be geofenced to allow them to clock in during office hours.
- Analytics And Reporting
Employee monitoring software that is successful should be able to gather as well as evaluate numerous metrics. The study is required to assess staff productivity and identify areas for improvement. Employers, for example, might learn how to prioritize work differently or automate repetitive manual activities. Your employee productivity tracking software should show all important gathered metrics in a simple format, such as dashboards and graphs, to analyze. Managers will be able to get a complete picture of employee performance and compare productivity ratings among employees, which will affect decisions regarding promotions, compensation evaluations, extra training, and other matters. It’s ideal to choose a solution that allows you to assess project efforts and resources by combining data and metrics from many internal sources into a single integrated system.
Overall, your company should choose an employee tracking software that is simple to connect with your current learning management system. As a result, businesses want a low-cost staff monitoring system that secures and controls everything to win their remote work fights.
