海外TECH	DEV Community	A Beginner's Guide to Installing Linux OS Using VirtualBox on a Windows Machine.	https://dev.to/rejoice/a-beginners-guide-to-installing-linux-os-using-virtualbox-on-a-windows-machine-3ge4	A Beginner x s Guide to Installing Linux OS Using VirtualBox on a Windows Machine On a Windows machine there is only one operating system OS available which is the Windows OS pre installed and used by default which powers the computer An operating system is software that allows one to use a computer and maintain its efficiency by handling all of its hardware resources It is also the link between the hardware and software components of a device If this balance does not exist a desktop and laptop can simply not function Because many computer users are very familiar with Windows and may not like to switch completely over to Linux OS by installing it directly and configuring it to become the main OS on their computer systems it is advisable to host the OS on a virtual machine The virtual machine used in this article is VirtualBox third party software that enables virtualization It looks like this You might wonder how is this possible running two operating systems on one computer system This is possible by the presence of the Hyper V on the windows OS known properly as Windows Server Virtualization It is a hypervisor that permits virtual machines to run and allows for the virtualization of x servers on the computer At the end of this article you should be able to install Linux OS on your desktop or laptop using VirtualBox without having to get rid of the default OS To start simply search for VirtualBox on any search engine of your choice go to the official website and download the exe file There are several options for different OS click on that of Windows or simply follow this link to download it The Windows version is represented as x amd Click on that to download the file There are checksums to indicate that what you are downloading on your machine is secure and the same as what the developers have created It is displayed as SHA checksums and MD checksums on the page When that is done it will show up on your device as Oracle VM VirtualBox Manager Install it and follow the instructions given After this it will request that the file is allowed to make changes to the computer You are to click Next and move on to the next step VirtualBox is wonderful in many ways in the sense that it is an emulator It mimics the environment and makes it into a desktop Give the virtual machine whatever name you have in mind something descriptive create a folder for the machine that you can easily have access to located on the RAM of your local machine and choose Ubuntu bit as the type of Operating System OS amongst the several options present NB While downloading Ubuntu setting up the LTS version on your local machine is important as in Ubuntu LTS This will ensure that you receive any updates that are given It normally comes within a six months interval Any other applications without the LTS will become outdated with time Next you will be asked to select the amount of memory space that is to be allocated to the virtual machine Although the recommended memory is MB you can decide to add more depending on the overall space on your local machine Take care not to allocate too much as this will affect the local machine s performance After that you will be asked to choose a hard disk Choose the second option which is to Create a virtual hard disk now The recommended memory is GB For the type of hard disk choose the first VDI VirtualBox Disk Image although VirtualBox supports all three options available For the storage on the hard disk it should be dynamically allocated A fixed size may take longer to create and cause storage issues later on especially if the local machine does not have much space File location and size should be left at the recommended portion of GB out of the TB option displayed on the screen You can then Create This should be the result after giving the server a name of your choice This will then show the virtual computer that has been created on the left side of the panel under the section called Tools It is powered off on default After creating a virtual computer that will enable the use of another OS on the local machine it is important to download software that will enable its use Vagrant will be used to illustrate that in this article Search for Vagrant by HashiCorp to download and install A folder is to be created in the file explorer of your local machine for its running It can be named after Vagrant It is important to note that Vagrant does not have an interface so everything will be done in your local machine s command line terminal CMD using GitBash There is no need to install this it is already present in your Windows OS This is what the command prompt looks like An ISO image is to be downloaded and installed like a normal installation for virtual machines This is because while working with servers physical metal devices a CD DVD flash or external hard drive is needed to do the installation All of this is done differently on Vagrant Here there are already default boxes created that are hosted online When they are downloaded depending on your choice Vagrant automatically sets them up The following are commands that can be typed in the terminal to create a new folder and procure the boxes NB Do not forget to press the Enter key after each command is written so it can be initialized cd vagrant ls cd boxes Vagrant init is the command used to create the file used to proceed with the configuration Vagrant init ubuntu focal is used to install focal a box needed to initialize the function of Ubuntu Vagrant up is used to examine the configuration files and check if you have the necessary boxes needed If it is not present it automatically downloads it Vagrant upAfter all of this is done there might be a virtualization error when trying to run the Ubuntu server This can be corrected by enabling virtualization technology on your local machine To achieve this the computer has to be switched off and turned back on again Once it s turned on click on F immediately more than once if necessary to enter the system BIOS Navigate the environment with your arrow keys as the mouse may or may not work depending on the model of your machine Enable the Virtualization setup It is located under System Security It is disabled by default Save your changes and exit the BIOS environment The machine will switch on by itself after this is done The Ubuntu server will be able to function properly after this Vagrant ssh is used as the third and last command but it is written in the Vagrant terminal this time as the virtualization has been enabled Vagrant sshIt is used to be able to access the machine There is a welcome message that shows up on the terminal after this command is run An accompanying message might follow which asks for log in and password Input vagrant for both fields After following all of these steps you have successfully installed Linux OS on your local machine using VirtualBox as a virtualization compartment Wrap UpWe have gone through the process of installing Linux OS using a virtual machine without getting rid of the default OS Download and install VirtualBox first then Vagrant and enable virtualization in your system BIOS to ensure it reaches its full potential Linux OS is a powerful operating system and it s an amazing feat to comfortably access two operating systems on one machine I hope this article has been helpful	2022-08-19 14:44:26

海外TECH	DEV Community	How to become a developer	https://dev.to/arielbk/how-to-become-a-developer-58da	How to become a developerI landed my first dev job after about a year of self directed study I can still relate to it but over the past three years I ve also had time to reflect on the experience It was a rocky road and I did a lot of things well but there were also things I could have done better These are the lessons I learned   IdentifyI was afraid to commit even though I wanted to get into coding for a long time I imagined a job where I robotically wrote code all day and thought I may get stuck doing it forever I wasn t even sure what coding was and doubted whether I could do it After all I wasn t a maths genius When I faced these thoughts I realised I was holding myself back This did not have to be a lifelong commitment Take the time to figure out what coding is and what a developer does Find out what you re in for There are many ways that code can be used but the foundations are mostly the same Take the time to explore and keep an open mind Coding can be like a puzzle game solved by fitting pieces together and reframing the problem in different ways It can be frustrating sometimes but the satisfaction of solving the puzzle is worth it Learn what code looks like Watch YouTube videos or look at source code It can be overwhelming but a mass of code is just a lot of smaller pieces Immerse yourself If you re surrounded by experts you will naturally soak up some of their knowledgeGo to dev meetups in your area and embrace the vibrant online developer community Listen to podcasts They are a great way to maximise your time and keep you inspired and connected   LearnI d have dozens of tabs open at any time all relating to web development I read countless articles and tutorials The first course I took a free online introductory course to computer science was fantastic for building foundational knowledge Although challenging it was well structured I decided I would give the course a chance and then decide if I wanted to continue learning It s important to research and explore but eventually you ll want a concrete plan to anchor and guide you Your learning will be less efficient if you constantly shift focus Spend time exploring see what s out there and what you enjoy and then focus in Create a plan for your own learning It can change but only after deliberate consideration A danger on the other side is not allowing yourself to progress until you ve mastered every topic you come across Learn enough to be proficient and then move on You can return to something later to understand it deeply TutorialsUsing a whole tech stack can be overwhelming in the beginning and tutorials are great for guiding you through that But be careful it s easy to get stuck in tutorial purgatory ーdoing tutorials without applying what you learn Treat tutorials as a starting point and then decide if you want to explore things yourself or build out the tutorial project more   BuildIt was hard to step away from tutorials where everything was neatly laid out so I decided to block off the morning time for intensive work on my own projects At the end of the day when I didn t need to be quite as focused I followed along with tutorials and looked out for lessons that I could apply Building projects is where the real learning happens You will come across roadblocks but this is how you learn to problem solve Projects teach you to manage yourself Start out with something small and gradually expand your goals What to buildChoose a project that challenges you but not so much that it s overwhelming The sweet spot is when you re about comfortable with the whole tech stack There s no need to think of a completely original idea to start building Cloning an existing project is great practice Reverse engineer it and add your own spin   ApplyAfter about months of online courses and tutorials I started to apply for jobs I crafted a CV bio and cover letter describing how keen I was to learn I got interviews and many simply didn t reply I didn t have experience to list so companies weren t interested in finding out more I didn t let this discourage me I shifted focus to showcasing my work Over the next months I created a portfolio with side projects that were live and open source Once you land your first job you ll get to learn while working on real projects but landing that first job can be difficult without real experience Picture yourself working where you want and plot a path to get there Find a job listing you would like to apply for see what the requirements are and work on meeting them Do what you would do on the job before you have it and put it out there for the world to see You don t necessarily need a computer science degree to land a dev job Show off your code and let your projects be your qualification Open source your code on a platform like GitHub as soon as you can Push code often and keep your projects up to date Your code is there to show what you re capable of It should showcase how you think an app or website should be built Keep this in mind and be deliberate in the patterns you use Demo your websites It s much easier for someone to check out a demo of what you ve built get excited and curious and then dig into the code This time things were different I had projects to show and companies were actually getting back to me I interviewed with a handful of them and received multiple offers I was able to negotiate and take my pick I decided to work for a startup in the IoT space and was excited to start my next chapter Being a beginner is difficult but your rate of learning is through the roof Basically anything you do will be a learning opportunity Let s recap the main points for breaking into a dev career Identify find out what what you re in forLearn plan a path and treat tutorials as a starting pointBuild build real projects and put them out thereApply do what you would do at your dream job before you have itOnce you land your first job your hard work will have paid off I m still amazed at how fortunate I am to have a job that s fun and that I look forward to doing Everybody is in a unique situation and people learn differently This is my experience but I hope these lessons can translate to other learners on their journey	2022-08-19 14:12:44
