Software

Let's talk about Software. How to do things and how to solve problems. Problem on Windows, on Linux. Gimp tutorials and other tools like virtual machines, etc, etc.

We use operating systems and programs every day. Many times problems arise that we do not know how to solve and other times we generate them ourselves by not doing things correctly.

Sure you use the computer in your work, do you get the right performance? Do you have optimized processes or can you automate much more? Surely there are tools that allow you to increase productivity, or some change in them or the way you manage it.

Well, we are going to see tricks and tutorials for all these kinds of things.

How to navigate with the ip of the country we want with TOR

sail with tor through the country we want

Sometimes we want to navigate pretending that we are in a certain country, that is, hiding our real IP and using another from the country we choose.

We may want to do this for many reasons:

browse anonymously,
services that are only offered if you navigate from a certain country,
offers when hiring services,
check how a website that contains geolocated elements works.

In my case it was the last option. After implementing several plugins on a WordPress website, I needed to check that it displayed the data correctly to users in each country.

How to run .sh files

how to execute sh file — Discover how to run it with the terminal and double clicking

International shipments may take up to files with extension .sh are files that contain scripts, commands in bash language, which runs on Linux. SH is a Linux shell that tells the computer what to do.

In a way we could say that it would be comparable to the Windows .exe.

There are different ways to run it. I'm going to explain 2. One with the terminal and another with the graphical interface, that is, with the mouse, that when you double-click it is executed. You can see it in the video and below is the step by step for those who prefer traditional tutorials.

Recovering an old Linux computer

computer brought to life thanks to a lightweight Linux distribution

I continue with the PC and gadget repairs although this cannot in itself be considered a repair. But it is something that every time they ask me more. Put some operating system that makes them work on computers with older or older hardware.

And although I tell you a little about the decisions I have made in this specific case, it can be extended much more. I will try to update and leave what I have done each time the case is presented.

Follow the series of articles on computer repair. Common things that anyone can fix in our house like when the computer turns on but you don't see anything on the screen.

How to convert tables from PDF to Excel or CSV with Tabula

Looking at the historical data offered by a meteorological observatory in my city, I see that they only offer them graphically and for download as PDF. I don't understand why they don't let you download them in csv, which would be much more useful for everyone.

So I've been looking for one solution to pass these tables from pdf to csv or if someone wants to format Excel or Libre Office. I like csv because with a csv you do everything you can handle it with python and its libraries or you can easily import it into any spreadsheet.

As the idea is to get an automated process, what I want is a script to work with Python and this is where Tabula comes in.

Anaconda Tutorial: What it is, how to install it and how to use it

Anaconda Data Science, big data and pytho, R distribution

In this article I leave a Anaconda installation guide and how to use your Conda package manager. With this we can create development environments for python and R with the libraries we want. Very interesting to start messing with Machine Learning, data analysis and programming with Python.

Anaconda is a free and Open Source distribution of the Python and R programming languages widely used in scientific computing (Data ScienceData Science, Machine Learning, Science, Engineering, predictive analytics, Big Data, etc).

It installs a large number of applications widely used in these disciplines all at once, instead of having to install them one by one. . More than 1400 and that are the most used in these disciplines. Some examples

Numpy
pandas
Tensorflow
H20.ai
Scipy
Jupyter
Dask
OpenCV

How to see hidden password with dots or asterisks

How to see password that we have forgotten and is hidden by dots or asterisks

Sure sometime You have forgotten a password but your browser remembers it even though it is hidden with dots or asterisks and in the end you end up changing it. Well, there are several methods to see this password, I know two, go to preferences of our browser to see where it saves the password and the second is the method that we are going to teach very, very simple and more powerful because it allows us to see passwords saved in fields , that is to say, that although we have not saved them and of course, it is not in our browser, we can see them.

This is very useful if for example you work as a team and someone puts an API in a form, as in WordPress, this way you can quickly retrieve it to reuse it elsewhere.

I leave you the video with teaching how to do it and below I explain the two methods in traditional format (inspector and browser password manager)

How to edit images in batches or batch (in bulk) with Gimp

BIMP GIMP plugin to edit and manipulate images and photos in batch

Easier Gimp as a photo and image editor. I haven't touched Photoshop in a couple of years. Even when I was using Windows I stopped using Photoshop because I didn't want to hack it.

There are different ways to modify images in bulk, in bulk, in batches or bulk, whatever we want to call it. But this Gimp extension seems indispensable to me. Allows us scale images, add watermarks, rotate them, change the format, reduce the weight and many other actions that we will do in bulk and in a very short time. You will not believe the amount of time you are going to save.

I use it mostly to edit the images of blog articles. I size them right, add the watermark, and reduce the weight in seconds. But I find it useful for many people besides Webmasters, photographers who want to add watermarks. Or if you want to change the size of several photos or images at the same time

I leave you first what it does and then how to install it in case you are interested.

Six months with Linux

Lately many people in my environment ask me about LinuxThey even want you to install it to test it. So now that I've been using Linux for everything for 6 months, I think it's a good time to share my experience.

Easier Ubuntu for 6 years on the laptop but not intensive way or to work, the laptop is for leisure, browsing and some Arduino stuff. For a long time I tried to install some distribution on my PC, but my old GForce 240T graphics gave problems and although they tried to help me to correct the problems and install the correct drivers, in the end I got tired and continued with Windows 7 and then 10. I tried Debian, Ubuntu, Linux Mint, and some more and I could not install any. The truth is that I no longer remember if I tried something that was not based on Debian.

But a few months ago I had a Manjaro distro ready on the USB and I thought why not? and see where it worked and also great. I love Manjaro. I have been using this distribution for about a month and I fell in love with its Theme Maia. But there was an update that gave problems again with all the Nvidia (Rolling Release stuff?) So I tried Kubuntu, which had never been able to install it and had no problem. And so I've been using Kubuntu for more than 6 months in my day to day.

My first impression with Ubuntu

I've been using Ubuntu for two weeks. After posting the article on how to use ubuntu from a USB I decided to install it together with windows 7.

The extremely simple installation, from the same USB, made the partitions by itself, and with 3 or 4 clicks to work and then the surprise arrived.

Use Ubuntu Linux from a USB

This weekend has been a black weekend when it comes to PC. After a long time with problems, my windows vista decided to stop working.

After several formatting-installation-formatting-installation, it seems that windows 7 heeds what I say, although I still have a half hard disk with information that has not been deleted.

So I have decided to try other options, which go through a Linux distribution. On the page of Ikkaro from Facebook, I have been recommended Ubuntu, which I have already heard a lot about.
