kipuamutay :: Empowering the pymes

Our main product the Sales and Inventory System is coded in wxwidgets, QT is the alternative to wxwidgets for cross-platform development, when we decided for wxwidgets, QT still belonged to the company Trolltech, this factor decided our inclination to wxwidgets. However, recently, we have seen the need to port the OneHandMenu (was coded in Gtk for the Nokia N900) to QT for the Nokia N9 which uses Meego as Operative System. With this on our mind, we are taking the opportunity to port the timelineApp to QT before porting the OneHandMenuApp to QT.

Our telephone. The Nokia N900 is still fully operational until today-2023 (this article began to be written in 2022), and we hope that it will continue to function for many more years (as long as the operators allow it, since each time they try to turn off the old cellular networks and focus only on new ones like 5G), although migration to another phone with GNU/Linux and keyboard seems inevitable in the near future, or when the N900 stops working (such as stops connecting to the cellular network easily).

This video complements the article on the release of faena App.

In times of pandemic, when we all had to work from home, it was a bit difficult to concentrate, especially if you have small children who, at the same time that you are connected to your work network, your children are also connected to the network. from their respective schools. And most of the time when your little ones have a question, they don't wait for you to have a free moment to answer their question, but they immediately ask you about their question. In this new work environment at home, sometimes it is difficult for us to have a clear picture of all the tasks or requirements our bosses entrusted us with each day. Are we able to remember what we did or what tasks we worked on exactly four weeks ago? Or maybe simpler, a week ago? If the answer is YES, then faena App is not for you. If the answer is NO, faena App is for you, with discipline you will be able to record daily how much time you dedicate to each of the activities that you needed to carry out to complete a certain task.

This is the second part previously announced. In the first part we have configured the discount-card-for-frequent-customers-application and we recorded the attendance of a few participants. In this video we will be live coding a report that will allow us a more common view for an attendance app.

Is there a need for an attendance control system? We believe the answer to that question is 'YES', it is always necessary to keep a digital record of the people who attend an event that we organize, perhaps also a meeting. This allows us to monitor whether the message we are transmitting is at least being heard by the listeners to whom we impart the message. As the application of discounts for frequent clients keeps a register of the times that a customer receives a service within our business, then it becomes very easy to modify the discount-card-for-frequent-customers-application and turn it into an attendance control system.

When we make our videos about our applications, it is always necessary to unzip the files that we publish for win32 in our domain. We unpack them within our videos, making use of Emacs. However, we believe that we should make a simple how-to guide. How a user who downloaded one of our applications should proceed?, when using his/her machine with the most used operating system on his/her laptop.

We already have more than 11 years publishing articles or blogposts. And we still have a hard time posting regularly. We have several articles that we will be publishing shortly. We already have the titles of these articles defined, but the process of publishing each article takes time. People or organizations that make videos on YouTube always comment on the production time it takes to post a new video. Well, the same thing happens to us. Writing each article or blogpost takes time.

If you produce videos within your website then you will need to store the videos somewhere. Normally in your own domain you will have space problems, since you will soon fill the quota of your hosting service. If you are lucky enough to have your own server, many of the limitations mentioned in this article are not for you.

Having modified the loyalty-card app aka customer loyalty app. We decided on making a new version of the video done in the past showcasing the functionality of this app.

Why FreeBSD? Being users of various GNU/Linux distributions, the most recent being ArchLinux. BSD has always been a pending issue. So we did not miss the opportunity to see how FreeBSD behaves, with more than interesting results.

In our previous article We mentioned about 'reinstalling emacs23', that's the purpose of this article.

The emacs23 is the 'speed of light' version of Emacs. When We are editing C code nothing beats emacs23. Would that affirmation be Right after trying gccemacs?.

Testing Triple DES implementation on C language on GNU/Linux.

Any modern vehicle with a year of manufacture after 2000 has a computer. When the vehicle fails, the computer reports defects and the condition of certain parts inside the vehicle. But we're not talking about that computer. Instead we are talking of having an orange pi, a small computer the size of a credit card that has the same processing capacity as the cell phones we use every day, it just does not have a screen that indicates that it has already turned on, nor does it come with a keyboard nor with a mouse, it is a computer without a screen, not like the altair of course. And what's the use of a computer without a screen in the vehicle? It makes some sense to have a computer of that type in our vehicle.

The application that today we will port to commonQt is a note management application, the application allows us to create notes and then easily search any term or keyword within the set of notes created. This application uses sqlite as the backend database.

Within our company, we are used to doing web scraping with python and selenium. But we have encountered an obstacle 2 Gb of memory are not enough when you open more than 30 tabs automatically with the chromium. The machine becomes very slow due to lack of memory.

One thing that is always missing by default in any GNU/Linux distribution is a quick and easy way for sending and receiving files through bluetooth. In the previous article we saw how to receive files, this time we will see how to send files by bluetooth from the command line.

One of the things We dislike about the Unix desktop is not having properly working bluetooth on our workstations. Some things that are so simple like sending and receiving from our workstation are very uncomfortable and also something difficult to fix.

In the previous article one hand menu we have shown how the navigation menu is constructed based on a file, the goal of this post is getting emacs helping us to modify the configuration file graphically.

Making phone calls with one hand, kinda difficult, right?.

Our developer pinwino has been working on this application. It is a Customer Loyalty Card. We think this application is going to be very useful for some business. If your business have been trying to get customers return sooner to take your services this is going to work for you and your business.

Printing is a piece of cake, Right?, an end user just needs to press the print button, and documents start to flow through the printer. For our inventory system the case is going to be different, our inventory system (InvCross), is being developed on C language and the user interfaces done on ​​wxwidgets (C++). The printer our inventory system is going to work is a printer that supports ESC/POS . So the requirement is "print from c language to an ESC/POS printer".

Showing part of the Inventory System User Interface.

Workstations are very important elements of our workflow when working well, we all see its limitations, on the other side when they stop working is when we realize how useful they are even with its limitations.

When we developed the wxtimeline, we took the decision of making it public domain. At that moment the idea was that developers where going to compile and use the wxtimeline. A few days ago we wrote the wxtimeline post second part. One of our readers let us know the video was not user friendly. Let's fix it.

In our previous article of the timeline also known as the missing wxWidgets sample we published all the source code of this versatile application. We have at least a couple of users. Today we are going to see what we can improve on the application.

Flashing BIOS on Linux should be a painless process. Manufacturer do not support GNU/Linux enough. We hope them to provide us with the images needed for flashing the BIOS.

After keep working on maintaining our blog at kipuamutay, it's time to improve our tools for writing articles regularly.

Quick App with wxwidgets

From our time as Palm developers, we missed the great calendar application that Palm used to provide us, as the global search feature too . Sometime ago We did something similar with ror. The timeline on ror was very easy to do, the only annoyance we found was having to start the app every time we need to register a new event on the ror timeline. We were in the urgency to find something more comfortable to use.

Years has passed quickly, now we have wxwidgets as part of our tooling. So why not give the timeline a try on wxwidgets. Our goal is to put the timeline on the n800 and having again it at hand (literally) when needed.

When we are learning a foreign language as the English is, it is good to improve our ear, what worked pretty well for us was listening english songs and follow them with the lyrics.

Archlinux is the distro that keeps the momentum. ¿How is It? arguably It is the users craving for the latest package versions and avoiding reinstalling or upgrading the distro after some time frame.

Also, last versions of major desktop environments are not very kind to older hardware.

As time passes on, we collect valuable information on our hard disk. What to do when we got a failing hard disk?. The right answer would be reach your last backup. Few people could be so lucky that the last backup covers all the info you need.

How to setup the palm development environment on 2011

A little history

Developing Palm on the last years, is not an easy task. Palm is a platform that is being left behind by the device's manufacturers and it's own parent company. The Palm company has suffered several division processes, fusion processes, and stakeholders change. All those changes has left us a brand without presence. When we are referring to Palm, we refer to the devices made by Palm or the ones that use the PalmOS, also are included the devices than use the GarnetOS, we are not referring to the devices that use WebOS¹.

There are several tools and workflows for writing a blog, after reading the article writing and blogging on org-mode, We noticed blorg as an alternative, after reviewing the blorg page It was discouraging to notice blorg was not going to be maintained, we needed to start looking otherwise. Writing and publishing from emacs-muse is easy. First we were trying to know how the emacs-muse authors were publishing their blogs, we found out by the examples they were using blosxom (it uses a python script for publishing), We were looking for a tool that uses just emacs. Then after googling We were directed to muse-journal, after trying it, muse-journal does the job, then We decided for muse-blog after comparing it against muse-journal, was a very difficult decision, both tools do the same, also the documentation for both tools is scarce but It seems even the emacs-muse authors do not encourage muse-journal enough.

Some years ago we have had installed Archlinux in an external hard disk. When we were working on doing our first PKGBUILD, this external hard disk came to the rescue. We copied /boot and /root to repair our development laptop. You know, we have the common practice to take notes about some uncommon procedures like this one, but we have lost that group of notes when losing an 8 Gb pendrive. Also, we did not have a backup. Inside this pendrive We had the requirements for our inventory system.

We use wxwidgets for developing our inventory system. We used the 2.9.1 version for publishing our windows version and solving some bugs with the previous version.

When You want to be an entrepreneur You have several options for creating Your website. One of the options is 'Do It Yourself.

We have used emacs and emacs-muse for creating our website.
