Google Classroom: How to Teach Online Classes from Home for Free

The company Coronavirus causes the number of students who are taught at home on a sharp rise. There are many alternatives to online distance learning , but one of the most popular in recent days is Google Classroom. We will explain how to use it and all its details.

Google Classroom was launched in August 2014 and can be used in personal Google Accounts from 2017 without a G Suite subscription. It was initially designed to save paper, but its utility surpassed its initial use to distribute tasks or evaluate content.

Google Classroom: How to Teach Online Classes from Home for Free

As the name suggests, it allows you to have virtual classrooms, which not only allows teachers and students to interact more seamlessly at a distance, but parents can be more informed about the whole education process.

And, as we’ll see, it’s probably the best tool we need to learn online, because it also allows us to join Hangouts Meet for video calls and have a complete virtual classroom experience.

How to create a class using Google Classroom

Accessing Google Classroom is really easy. We only need to create access to classroom.google.com using our email, either our personal account or an account we created specifically for classes if we don’t want to reveal ours. From there we’ll be inside.

At the top right, you’ll see a “+” icon where we can join the class if we are a student or create a class if we are a teacher. If we are a teacher, it is important to know that if we are going to teach in a Learning Center with students, we will have to create a free G Suite account for the Learning Center.

To create a class, we can create a class, section, subject, and class name. This allows students to easily identify subjects and classes. From here we will have created our class with the class code that we will have to give the students to get into it.

In the panel, we can select a class subject, upload a personalized photo, send messages to all students, create classroom tasks and queries, and organize work. We can also manage students and teachers with access from people, and finally also assess the work of students in the Stage section.

In the job creation section we can select Tasks, questionnaires, questions, materials, etc. We can assign points to each task and set delivery dates. For questionnaire tasks, they can be done using Google questionnaires.

Entering as a student is even easier

For students, this process is easier because you just need to click Register for Class and enter the code provided by the teacher. Once we enter as a student, we will have access to all the tasks available in the virtual classroom.

In short, we have many ways to continue evaluating home students with all kinds of everyday and homework, although unfortunately the exams cannot be performed remotely in the same way that they can be done in the classroom.

Despite this, as a temporary solution for the next weeks (and probably months) that lie ahead, it will help children keep up with the class. It is also important to remember that children do not overload their homework.

If you want to use the video call tool with Google Classroom, Hangouts with Google, it will be available for free until July 1, 2020 , so teachers can use it free of charge to communicate with students and remotely.

How to Block a Website or IP Page Using PowerShell

Block a Website or IP: There are many websites on the Internet. We have millions of websites in all languages ​​and with a wide range of topics. There may be times when we are interested in blocking a specific site. We want it to not open when you open your browser and enter your address.

We can do this in different ways. For example, we may use third-party firewalls and other tools. This will prevent our system from accessing a specific site. However, the operating system itself also has the tools to achieve the same goal in a simple and fast way.
That’s where PowerShell comes into play. We can use it to take a series of steps and block access to both a specific website and an IP address. You just need to do some simple actions that we will explain.

How to Block a Website or IP Page Using PowerShell

We’ll explain how to block the IP address of a webpage from PowerShell. Keep in mind that we can block a specific IP or a number of addresses. The first thing we do is start , write PowerShell and run it as an administrator.

The command to be executed is as follows:

New-NetFirewallRule -DisplayName -Block NAME.com IP address -Direction Outbound -LocalPort Any -Protocol TCP -Action Block -RemoteAddress ADDRESS

From this command, you only need to change two things: NAME and ADDRESS. In the title you must specify the website, domain; We will list the IP addresses of this website to the address. Later we will only have to give it to execute and the process will begin.

In our example, we tested a random site that we found on the Internet. The goal was simply to prove that it worked properly. Once launched, we can open Google Chrome, Mozilla Firefox, or any browser to see if the page loads. As shown in the figure below, a message will appear.

We can also access the Internet Windows firewall and check the output rules to make sure it is properly blocked. The page we’ve chosen to block appears. You can even right-click it to disable the rule. This way, we will be able to access this site again without any problems. The change is immediate.
In short, by following these steps, we can block access to any domain on the Internet in a simple way. It’s basically the same as creating a rule in Windows Firewall.

In this case, however, just run the code we mentioned, change the parameters and that’s it. We will no longer have to waste time creating rules of any kind.

As previously reported, we can also access the operating system firewall to check if the rule or rules that you created were actually saved.

In this way, we can ensure that they are really active. We can always cancel the action, and this way we can access the site we decided to block at the time.

Remember that this block will be present in every browser. It’s not something that can only affect Google Chrome or the main browser we use, but it will be present in anything we install. Finally, our system blocks access to this site or IP address.

How to Use the Bolsa App on Our iPhone, iPad or Mac

How to Use the Bolsa App: The Stock market app on our iPhone, iPad or Mac allows us to check the price of companies and currencies in the easiest way. It is a simple app to use and yet it has some details that are important to know.

The list of values, a summary view

The first thing we see when we open the Stock market app is a list of all the values and currencies that we have stored. In addition, we find the Economy News section that appears in the top half on the iPhone and at the top of the list on the iPad and Mac.

The economy news is grouped by each of the values ​​or currencies that we have stored in the app. The information comes from Yahoo Finance.

The list of values ​​itself includes the symbol of the value, its full name and a graph of the activity during the current day. We can also alternate between the percentage of change, the increase in points or euros / cents and the market capitalization (only available for companies).

To switch between this information we simply touch the small red or green value that appears in one of our values, the change will apply to all.

We can add, remove or reorder the elements of our list in a very simple way. To add a value we simply search for it and tap on Add to Favorite Values , which appears when we consult its details. To delete a value we simply slide our finger (two fingers in the case of the Mac) from right to left on top of it and press Delete.

Meanwhile, to reorder the list, touch the Edit button and use the three dashed icon (≡) to drag the value to its new position (on the Mac we dragged it directly).

The detail view, value for value

In addition to the general list of all the values ​​where, at a glance, we can obtain the information, we can touch each one of them to have more precise information .

The information we find appears in full screen on the iPhone or on the right side of the app on the iPad or Mac. It shows us the title of the security, the current price and the percentage of change or points.

Below we find a graph in which we can choose between one day, one week, one month, three months, six months, one year and two years. After three months, a graph of the volume of transactions is shown.

Below the graph we find key data such as opening prices, highs and lows, capitalization, highs and lows at 52 weeks, etc. We can scroll between this information by sliding from right to left.

Finally, under this information we find again the news related to the value that we are consulting. On the iPhone, in addition, we see at the top the information of the other values.

Without a doubt, an app with a very specific function and perfectly carried out. In addition to securities and stock indices we can add forex quotes, ideal for when we travel and want to know the currency exchange rate.

How to Retrieve Text from Dashboard Sticky Notes on macOS Catalina

Retrieve Text from Dashboard Sticky Notes: With the arrival of macOS Catalina we have said goodbye to more things besides iTunes: something that also disappears completely is the veteran Dashboard that has been increasingly ignored with successive versions of the system.

It is a change that has already been noticed in the betas, but that perhaps has caught you by surprise as well. If this is the case but you were only using purely informative widgets like the weather widget or the unit converter then the problem is not serious.

You simply have to look for alternatives like Spotlight or the same Siri to be able to do the same. But what if you had things written down on the Dashboard sticky notes (or post-it)? Has that data been lost forever? Well thankfully not entirely.

Retrieve Text from Dashboard Sticky Notes on macOS Catalina

Although the content of those sticky notes is recoverable, the process for doing so is somewhat technical. Follow the steps well, do not get overwhelmed with the unintelligible texts that you are going to see and you will get it:

  • On the Mac you have upgraded to macOS Catalina, open a Finder window .
  • Press the ALT key and, while continuing to press it, open the Finder ‘Go’ menu . You can click on the ‘Library’ folder.
  • In that folder, find and open the ‘Preferences’ directory (not to be confused with PreferencePanes).
  • If you were using Dashboard sticky notes, you should be able to find the ‘widget-com.apple.widget.stickies.plist’ file . Look for it exactly with that name, if it does not exist it is that you did not use the Dashboard sticky notes (perhaps you used those from the Sticky Notes application, still available in macOS Catalina).
  • Open that file with any program that is capable of editing text or code (TextEdit works):

You will come across a lot of unintelligible text, mostly HTML code. But among all that code you will find the notes you have written , and you can copy and paste the text to any other more modern application.
