Backstory (You can jump)
I work almost exclusively with Qt and with the design philosophy of
Expand everything as API
The particular practice of this question is the tracking of the members of the group, emitting signals whenever their value changes.
For example, here is a general way to treat class members with the philosophy of the API, namely that for each member, there are at least four components:
QUrl url (); // return a copy of m_Url
void setUrl (URL QUrl); // A designated URL creator
void urlChanged (); // emit a signal whenever setUrl () is used
QUrl m_Url; // the object itself, with its protected state
This has worked very well for me so far, since as soon as I have to add features that depend on
m_Url, I only have to do this:
connect (this, & MyClass :: urlChanged, & foo, & MyOtherClass :: doBar);
And this is reliable because, basically,
Now, I must say that HTML and web development were not my original strengths in programming, and as such, I did not understand why these signals would exist:
But, there was no signal for
htmlChanged. Instead, all you have is:
Which is a function that will capture the current state. I had to manually call him on a timer whenever I wanted to check for a change of state.
So that's what I did, and then I discovered that even the HTML code of a static web page, or at least the one I was working with, was constantly changing, in which the changes had not changed. no meaning, and that's why none of this signal has been included by Qt's developers.
The heart of the problem
So I know what you are saying, "
significant is a subjective and situational term ", so let me define what I mean by
It's an excerpt of HTML code, say about 10,000 lines, the change I noticed on a webpage:
change in this
and returns to a constant loop. The fact that it comes back to the original state in a constant loop is what makes this change
no Sensand for that matter, it's not something I know how to follow intelligently. My initial strategy of detecting each change in the html string and analyzing it over an interval seems to me to be a very bad approach.
The fundamental questions
How I intelligently discover and follow significant changes in HTML? For example, suppose that a single value changes in an HTML document of 100,000 lines; Do I repair the entire document, compare it and find the change, or is there a way to avoid all that and correct the difference?
What API design philosophies, or existing APIs, should I use when interfacing with HTML, which will give me the correct signals for code injection or the right time for it? data extraction?
The answer should ideally take into account that the backend is Qt / C ++ oriented so that I can easily interface with the other libraries I depend on. I can do things like inject JQuery into the web page, or follow printfs and others. If that counts, the current engine I'm using is based on Chromium, https://wiki.qt.io/QtWebEngine.

What some of our recent customers say:
Wizzsolutions, what can we say?
Their staff went above the call of duty. We hired them to secure our server, and then they moved all our sites from our old server to the new /
It was a nice budget to work with them, excellent communication.
We would use them if we needed them and give a positive recommendation to find this type of service.
Originally, I contacted wizzsolutions because I was interested in a server security service provided on an ad hoc basis. My contact with the team, especially with Michael, convinced me to sign up for a regular monthly subscription for help. I have looked around me and I have not found any better service for my Centos server plesk in the price range I am paying to Wizzsolutions. Our partnership has been around for several months and I wish Michael and his team a lot of success with the new WizzAdmin services.
We had experience with many management companies, but believe me, wizzadmins are superior to all those. They know what they are doing and I think they like their work. All the technicians are qualified and competent. They helped me and helped me beyond my expectations.
What else could I say, these guys are just great. And I'm really happy to stay with them.
We used WizzSolutions to configure a disaster recovery server to ensure high availability and availability. Their team is very competent and provides excellent support and sound advice.
Although they took a little longer than expected to provide the configuration, they did everything to put our systems into service and test them before delivery. They also helped us with tasks that were not even part of their services.
We are really pleased with the quality of their services and we will soon turn to their managed solutions.
Thank you for your visit and look forward to working with you soon!

All roads lead to Rome. Ok, it's a classic for an article that explores the beauty and exuberance of the Eternal City, but if you're not alien to the journey, you know that one way or another, wherever you go, you will find yourself at Rome some point. Whether or not your visit to Rome is on your list of priorities is definitely something you should do with your life, because it was the capital of the world at one time, and we have every reason to prove it.
Modern Rome is a mixture of influences, where the urban drone collides with the eternal silence of ancient sites and you get an absolutely seductive result. Whatever your interests and passions, wherever you come from, you will find something for you in this city, be it fashion, gastronomy or always charming Italians. To that end, we present you the 10 best places to visit in Rome.
10. Piazza Navona
If you want to spend days walking in beautiful places often hidden with a unique charm, Rome is your city. Seeing that we try to cover the 10 best places to see in the Italian capital, we must mention Piazza Navona. This is one of the most tourist sites, it's true, but when you get there, you'll understand its appeal. This is one of the most important and well-known squares in Rome, and it has a rich history, since it was where the Domitian stadium was a few millennia ago. Formerly seen on sports events, Piazza Navona is now lined with small cafes and cozy restaurants (always crowded) that offer rest to tired travelers, provided they do not fear the noise of tourists. What makes this place more special than others are its beautiful fountains. The most appealing of these is the Four Rivers Fountain, which is not only large but also hypnotizing in its craftsmanship.
9. Villa Dei Quintili
If you want to see how high consuls and influential people lived in ancient Rome, visiting Villa of the Quintili will be a treat for you. It is not located in the heart of Rome, but rather on one of the countless roads leading to it. This villa was once the epicenter of political plans and intrigues, thanks to the fact that it belonged to the Quintili brothers, who accorded great esteem to Marcus Aurelius as to his esteemed advisers. However, times have changed, as has the emperor, which led Quintili to fall from grace and to be executed in his own home by order of the Emperor Commodus. Today, thousands of years later, when you arrive in this villa, you will see some incredibly well preserved Roman baths, not to mention the fact that whole buildings are still standing, proud to withstand the time that past. If you want to wander through a more peaceful landscape and feel the energy of the past, Villa Dei Quintili will be your cup of tea.
8. Capuchin Crypt
We are not talking about Capuchin monkeys here, in case you are wondering, but of the order of the Capuchin friars. This religious order has existed since the 16th century and they have dedicated their lives and deaths to their vision of the world, which we literally mean. Just below the church Santa Maria Della Concezione Dei Cappucciniare, six small chapels adorned with the bones of 3,700 brothers who served the order and died for him. Even though it is a bit weird and morbid, the Capuchin crypt shows how to turn the deceased's bones into works of art by simply organizing them in the right direction and, if in doubt, discover the crypt of the skulls. At bottom, this crypt is a vivid but macabre reminder that life is ephemeral and must be cherished as such. Keep in mind that taking pictures is strictly prohibited on this site.
7. Church of San Luigi Dei Francesi
If Italy does not miss things, it is her painters and her churches that they have transformed into artistic jewels by their brushstrokes. There are many sites throughout the country that must be visited to feel the energy that ancient artists put in their paintings and Rome is a great place to start. The Church of San Luigi Dei Francesi houses the Baroque art of Caravaggio, where you can find "The Call of St. Matthew", one of the most recognized works of the painter. If you are a fan of Caravaggio, this is a place not to be missed. An added benefit is that there is no admission fee. However, be aware that this church closes every day from 12:30 to 15:00, so you can plan your visits accordingly.
6. Trastevere District
We will speak in a few moments of some very touristy places in Rome, but we also want to devote our attention to more authentic and less populated areas of the Italian capital. The Trastevere district is much more discreet than the city center and you can be sure that you will have a better overview of real life in Rome by visiting this neighborhood. The jewel of Trastevere is the Church of Santa Maria, considered one of the oldest churches in the entire city of Rome. It's majestic and breathtaking and certainly worth a visit, as well as the entire Trastevere district.
5. Campo de 'Fiori
You have probably heard of Campo de Fiori, especially if you come to Rome to explore its nightlife, among others. This is a place that offers its visitors two completely different faces: one is the living and lush market during the day, and the other is the paradise of the bars that jump during the night. The market offers everything and anything to potential buyers, all you have to do is find it in the endless rows of suppliers. There are innumerable restaurants and all possible variants, from ice cream parlors to simple cafes, there is something for everyone. As night falls in the city, head to Campo de Fiori to discover how Italians are switching their night life and do not plan to leave before seeing the day again.
4. Vatican City
The city-state of the Vatican does not need to be presented because it is the heart of Roman Catholicism and not visiting it in Rome would be quite close to a crime. We do not say that from a religious point of view, but from a cultural point of view, because there is so much to see in the Vatican that you should spend a few days exploring this city of Rome. The Sistine Chapel and St. Peter's Basilica are just the tip of the iceberg of the Vatican's museum treasures and you will be amazed by the beauty and knowledge you will find there. Whether you climb 323 steps to the top of the dome of St. Peter's Basilica to see all Rome in front of you or quietly admire Raphael Rooms, visiting the Vatican is an experience not to be missed.
3. Borghese Gallery
If you want to enjoy the splendor of Italian art, you should go to the Galleria Borghese. Although it is a little difficult to get the tickets (you have to book them in advance and their price is 11 euros), two hours to spend in this villa-museum are well worth it. The view itself looks like a castle with its amazing architecture and gardens surrounding it, but what is really worth visiting this museum are the masterpieces on display inside. Sculptures and paintings by big names such as Bernini, Rafael, Titian and Caravaggio will attract your attention and two hours await you during your exploration of Galleria Borghese.
Whoever goes to Rome takes a picture at the Colosseum, it is his tradition. This former gladiator stadium is located in the heart of Rome and there is no chance to miss it because it dominates the panorama and the queues are quite negligible. Thanks to its unusual architectural design and bloody history, it is virtually impossible for anyone coming to Rome to come and study it more closely. We strongly suggest that you reserve your tickets online to avoid queues and, whenever possible, ask a tour guide to discover the meaning of this place as it is well worth it.
1. Roman forum
Among so many curiosities of the eternal city, the Roman Forum rightly deserves the first place. If you are interested in modern Rome and all its wonders, then you have the whole city at your disposal, but the Roman Forum portrays the old glory of the city and it has a lot to show. First of all, there is no admission fee, which is a blessing in itself, but it is a minor advantage over the monumental remnants of old buildings, shrines and houses that you can see when you are walking around. The ruins may not seem very fun, but you will change your tone as soon as you come to the Roman Forum, knowing that its energy and unique beauty will be enough to hypnotize you for several hours. The remains of the Temple of Saturn, the Arch of Titus, the Basilica of Maxentius and the Forum of Trajan are just some of the grandiose monuments of the glorious bygone era. If you have any interest in the vast history of Rome, the Roman Forum is the place to visit.
As in any other capital, exploring Rome will take all your time and you'll always feel like you're not getting enough. These ten places are a good place to start your visit, but you certainly should not finish it here, but think outside the box and explore for yourself. – Theresa Brawner
