However, the article is more general since there is no reference to GNU operating systems (e.g. GNU/Linux, GNU/Hurd).

If find missing delete then its not a GNU/Linux distro.

I didn’t want to use ‘-delete’ since this option might be missing from some versions of ‘find’.

We could use also ‘-exec rm’ but both ‘-delete’ and ‘-exec’ are for GNU find.

Other versions might not have these smart options yet.

Now get off my lawn…

Either through email or you can find me at TheHackerspace in Kalamaria!

Be well!

Sorry for the noise

But thank you for your interest

I do not think you understand how recursion works…

Yes, the code does not implement a sorting algorithm, but is simply an example of sorting strings. I will soon fix the title so as not to confuse other readers.

Also, I have attended in the past these videos you recommend. Moreover, I have known the “quick sort” for several years (as a recursive / iterative method “divide and conquer”).

I do not study “Algorithms & Data Structures” in this period (I did so several years ago – now I find out about what’s new in this area) but I try to create a collection of useful algorithms and data structures for those interested.

Finally, I am familiar with the issue of C and C++ you mention.

It is true that it is good to program clearly using either C or C++. I try to keep this rule when necessary, but not always. For example, when working at the kernel level or device drivers I only make use of GNU C. While, when I develop an object-oriented project, I use only C++.

Finally, I am not very interested in this issue in the examples I quote (those that do not exceed 50-100 lines of code). Personally, I think it is more important to understand the algorithm rather than to use the tool. You’ll also notice that I don’t make many white-box checks in the source code when the examples are simple (once again to emphasize only the steps of the algorithm).

Be well!

The sorting is done by ‘qsort’.

The code you show is just the “boilerplate”.

If you learn programming, it is worth knowing how qsort works from the “inside” since it is a very elegant and smart algorithm. I suggest you watch the video of lectures on algorithms at MIT.

In this as well as in other relevant posts I notice an “identity crisis” in your code between C and C++. My opinion is, since you pay the (considerable) cost of using the standard library of C++, to try to make the step and write full C++ code (for example, to use the templated version of qsort in order to remove the function pointer).

Yes, indeed, there are some issues concerning validation; however, we are not so interested in this matter in this work as much as for it to be finalized as soon as possible. Most errors come from within the Joomla plugins and modules and not from the user interface (template) and the code we wrote. Generally, this development took several hacks both Joomla itself and in the modules. The good news is that the site is working properly in all browsers.

Be well!

I checked a few pages out of curiosity with http://validator.w3.org/ where you will see some little mistakes that can be corrected. Also, if you could avoid the use of tables in the page layout, it would be ideal, but this requires changes to the template.

The attraction of insects to the box and their movement inside it will generate random vibrations.

I think it is quite economical.

Well, ants will also need food occasionally. This will be offered by spraying substances.

It is quite interesting.

I also suggest installing a moisture sensor to irrigate only those in need of water, not all.

As for the ultrasonic sensor, it will work fine.

Only take care that you do not use transparent glass to do the testing.

I appreciate that you mentioned me in the article on the ultrasonic sensor.

Be well. Keep us informed!

What you mention consumes much energy.

However, I think a sound sensor with a radio close is enough.

If we need peace and quiet, we will have to think about alternatives.

I’ve tried this before.

Thank you and continue to write such nice posts. I watch with undiminished interest all articles on code.

If you find possible errors or anything you think could be improved, please inform me.
