A bit of C++

C++ is a general-purpose programming language that was developed in the 1980s as an extension of the C language. It is an object-oriented language, which means that it supports the creation and manipulation of objects, which are instances of classes. C++ is a compiled language, which means that source code is transformed into machine code that can be executed directly by a computer. It is a high-level language, which means that it is designed to be relatively easy for humans to read and write, while also being capable of expressing complex computations. C++ is widely used in many different applications, including operating systems, video games, scientific computing, and finance. Its popularity is due in part to its performance, which is often superior to other high-level languages like Java or Python. Some of the key features of C++ include its support for classes, templates, and operator overloading. It also includes support for low-level programming, including pointers and direct memory access, which makes it a powerful language for system-level programming. Overall, C++ is a versatile language that can be used for a wide range of applications, from high-performance computing to graphical user interfaces. Its popularity and flexibility make it a valuable language for developers to learn and use in their projects.

labs we did with juanma

Yesterday Juanma put a labs about connecting switches and routers between them to give wifi to our pcs but we had a problem with the switches and routers because it didn't work. for our luck Juanma helps us after a long time with a lot of errors in the switches and routers, but we had another problem that we didn't have the infratestructure that juanma said to have and when he asked us to do a wireshark to search the apache it didn't show in the wireshark because we didn't mount it in the debian we only had the dhcp. the other day we had another problem with the same thing (not the infrastructure but the switches and routers) and I hope that the next time he will say to do the labs again we will do it perfect.  

Today's class (Raúl García)

 I started my day with AWS class, we had to make diferent virtual machines on amazon web services, so we could put a web page, on which you had to register to see it. I wasn't sure about how to make the "EC2 instances" so I had to watch a YouTube video, I didn't had enought time, but next week we will have more time. Next we had english class, we started with an exam, for me it was easy, so I didn't had any problem there. After that the teacher presented the new project we had to do, on which que have to make a job interview with a teammate in two weeks. I will make the project with Samuel, he is one of my best friends here in puenteuropa, we will do great for sure!

vpn explanation

  A VPN, or Virtual Private Network, is a technology that allows users to securely connect to the Internet over an untrusted network, such as a public Wi-Fi network. When a user connects to a VPN, the VPN server creates a secure, encrypted tunnel between the user's device and the VPN server. All data transmitted between the user's device and the VPN server is encrypted and protected from unauthorized access or interception. This allows users to securely access sensitive information, such as financial transactions or confidential business data, even when using a public Wi-Fi network or other unsecured network. VPNs are also useful for users who want to access content that is restricted by geographic location, such as streaming services or websites that are only available in certain countries. VPNs are typically used by individuals, businesses, and government organizations to protect their online privacy and security. There are many different types of VPNs, including remote-acces...
