Nueva aplicación de App Inventor : APP QUIZ

Hi!
We had just made an Android app with the program App Inventor .This app is in Spanish .
Our app is a quiz where you have to choose the correct answer among three options to get to the next screen.
Also the app has the feature text to speech,sound and different backgrounds.

Following there are some screenshots from our app

Initial screen

To start the game you have to press the button : JUGAR

First quiz screen

This is the main screen where you have to guess the question. When you choose the correct answer you go to the next screen.

This last screen has an option to exit the application .

Las Meninas.

We've created our own version of one of the most famous Spanish paintings, Las Meninas by Velázquez. We used Inkscape which has been very useful for us during this process of painting. This is what we finally obatined, it's not as the original one, but you can easily recognize the painting.

The steps that we followed were this ones:
- First we downloaded the original picture of this painting.
- After that, we uploaded this picture to inkscape and zoomed it up.
- Once we had the picture close enough we started to paint over it following the lines which were already painted.
- Finally, as we had all the lines drawn, we deleted the original picture from the background and started to color each of the section of the drawing with its own color.

Hope you like it :)

Pacman.

We've created our own Pacman following each of the steps in the instructions found in the link below:

Our final result is this one:

Then we drew two different cartoons which you've probably seen before ;)


We've chosen this two images below and basically did almost the same that we did with 'Las Meninas', some of the problems found are the following ones:

- We found it difficult to draw the eyes because instead of being perfect circles (which are the ones easier to draw with Inkscape) they were kind of irregular and we had to paint it manually. If you have the same problem, not just with the eyes but with any other part of the drawing, we recommend you to zoom it up even a little more, and so the line will look a little more precise.
- In addition, when you start painting the cartoon you will probably find problems (as we did) with filling the whole gaps with color. For this, the advice that we give you is that when you draw the lines, you should remark and connect precisely the lines which will form part of the same color section.

Microsoft excel: Bill.

Libreoffice vs. Microsoft Office (House plan)

 Again we are going to explain some differences between Libreoffice and Microsoft Office but this time showing a real example. We draw the plan of the same house first on Excel from Microsoft and then using Calc which is from Libreoffice. This are the main differences between doing the plan on Excel or Calc:

• The biggest difference between them is that on Excel you can turn the objects to make them face one side or anorther, but in Calc you can't do that, each object has to be facing the same side the whole time and you can not change that. As you can see in the second picture the bathtub and couch (in the second floor) have not the same position as in the first one because of what we have just explained.
• Also when we used excel we had to make just one door and then change its size or position deppending on the place we wanted it to be, but as you can see when we used Calc we couldn't do that, because doors were not as good and it takes a lot longer to do every single one of the doors in the plan each one with its own size and position.
• In the first one the difference between walls' and windows' lines is not too noticeable but in the second plan it's even more difficult to know where a window starts or a wall finishes.
• Another big difference is that when you draw for example a couch you need to put together to rectangles and then group them together so that you can move then as a couch and not as two separate rectangles, that is possible if you are dealing with Excel but not with Calc. This disadvantage causes precision mistakes when drawing objects which should be the same size and shape.
• Finally the last difference that we found was that Excel has some geometrical figures that Calc doesn't have and also the ones that it already has, as you can see in the circled bed on the second drawing.
  

In conclusion, for us it was easier to work on Excel because it has less disadvantages and then it looks better than using Calc, so for this kind of drawings we recomend Excel over Calc.

Magnitudes in Computer Science

We've made a Power Point Presentation about different magnitudes that we can find in computer science so if you are interested and you want to check it out, just click the link below:

Mirosoft Office vs. Libreoffice.

The following text explains some advantages and disadvantages of Microsoft Office and Libre Office as the previous one, but this time we are going to base our ideas on another person's opinion which you can see in the link below:

 http://techdidactic.blogspot.com.es/2014/07/libreoffice-openoffice-versus-microsoft.html

In this video there's a girl who explains Microsoft Office's advantages: It has most Office productivity tasks like for example, Document production, Spreadsheet formulation, multimedia presentation programs etc... She also says that its document format is the most commonly used.

She also explains some of the main advantages of Libreoffice like for example that it is free and available for Windows, Mac and Linux. It has Writer which is not too different from Microsoft's Word, Spreadsheet program similar to Excel, Impress multimedia presentation program which is similar to the PPT that we can find in Microsoft, also we can find Draw which is a diagram and sketch program as well as Math which is an ecuation editor and even more things.

However Microsoft has few disadvantages like the following ones: Obviously the main one is the fact that it is expensive and it gets even more as you buy extra things that are free in Libreoffice, she also says that it doesn't play well with all proprietary document formats and it has many different stability issues.

On the other hand we have Libreoffice which also has some disadvantages but lot less, the main one is that it can cause problems when dealing with very complexed tasks but it usually doesn't.

In conclusion, what this video says is that Libreoffice is a better option because it is almost the same as Microsoft but with less disadvantages, it is an incredible usefull tool, it can do few things that Microsoft can't and all this for free!
