My article [Tesseract Act](https://www.codeproject.com/Articles/5387592/Tesseract-Act) was incorrectly classified as “Web Development” as it is shown in the list under articles > Latest Articles. It has nothing to do with the Web in any sense. Generally, the presence of JavaScript is a bad criterion for Web Development. In this case, this is a Visual Studio Code API language used for development of extensions. There are other JavaScript uses. Interestingly, in the [personal publication list](https://www.codeproject.com/Articles/SAKryukov#Article) the same article is classified as “Node.js”. This is a bit closer, as the Visual Studio Code API and implementation uses Node.js. However, the topic could be classified better. Extension development is pretty popular and makes a separate class of software. Thank you.

Not only .webp files have a much better quality/size ratio, but they put to shame all those JPEGs, GIFs, and PNGs a long time ago, and .webp is de-facto Web standard. In addition to that, they support animation, and I have good plans for that. I remember that SVG raised the safety problem, but this problem is quite solvable. So, what's the current status? Thank you.

Not so easy, though, because there are many valuable assets, first of all, .NET. Also, they pushed into addictiveness many corporate people with the most destructive trash, like Office. In our jargon, we call them “office plankton”. :-) It feels like the main purpose of Office was to distract those people from real work and boost their self-esteem. :-) However, other sorts of office stuff are no better. But with those strongly enforced Windows updates, those guys test their luck. :-) Thank you.

Well, with those mandatory updates, Windows is trying to kill itself as a commercial project. Sooner or later it may happen unless they radically change the approach.

Even though it is true, there are some unwritten rules of politeness in publications. Thank you.

Nelek, Thank you again for the typo reporting! It took time to find time for that, and it took 7 (!) GitHub commits to getting it right because the typo also infiltrated in several places: 1) in both presentations, 2) not only in text, but also in graphical objects, and 3) in both articles themselves: [Web Presentation, an Application in a Single File, now with Video](https://www.codeproject.com/Articles/5286790/Web-Presentation-an-Application-in-a-Single-File-n) [Web Presentation, the Other Way Around](https://www.codeproject.com/Articles/5290221/Web-Presentation-the-Other-Way-Around) I also credited your reporting in both articles. Thank you.

Nelek, Thank you for the clarification.

the animation is actually an external file (i.e. *.WebP) so you can't jump to “the last line” of it...

Not quite. The animation comes in several ways: 1) animated bitmap file (for example, multi-layered (animated) .webp, 2) animated SVG, 3) just video, such as .WebP, that is, any media files, representable by a browser. If the video frame type is specified, it is done not directly, but by placing in a standard <video> element. Therefore, all these presentation frames (not to be confused with video frames) could be navigated to the next or previous presentation frame, at any time. But that's not all. The presentation doesn't have to be an external file. Also, it could be some HTML section, identified by the system by some simple rules, and that HTML fragment can be either static or it can use CSS animation. But CSS-animated HTML content is nothing more than just a state of a Web page, so it also can be navigated to the next or previous presentation frame. In fact, during the presentation, no one can even see the difference in the nature of the presentation frames. The only exception is the characteristic look of a <video> element with its well-known controls, but only it is not operating in a full-screen mode. I would say, all the power I see in this approach is its uniform behavior of all frames, no matter what is their nature. Thank you for the discussion again. I'll greatly appreciate any notes, ideas, suggestions, and especially any criticism. Thank you.

Sergey A Kryukov

Nelek, Thank you for sharing the ideas! There can be many things to think about. The issue with skipping is that you need to have some information on what to skip. This information can be the presentation frame itself. Maybe you did not pay attention: such a frame can already be skipped at any time, even if a video, based on an external video file, is playing. I still don't want to get away from a single file conception (the system is a single file, and the other files belong to the user). I also don't want to get far away from having just a list of external files of different types in a directory. It should always remain a primary usage pattern, the most basic and quick one. Also, in case you are thinking of something more complicated than that: the presentation users always see the same screen the presenter works with, there is nothing hidden. I am not at all trying to dismiss your suggestions. Just the opposite: I want to understand. I think the idea of the last frame (or first frame because you also can move backward) could be a valuable option. Perhaps, with the skipping, I haven't grasped the idea. Thank you.

Hi Nelek, Thank you very much for the advice and especially for reporting my typo. Speaking of which:

It was decided to make it totally error-free. They produced twenty proofreading prints and nevertheless on the title page it was printed: "Encyclopidae Britannica".

I'll certainly fix it as soon as I get to it. As to “no final slide”… you know, I've used it for many presentations already and never felt someone needed to know a final slide. Even an accidental step to the next round was perceived normally. And I did not quite understand how it was possible to miss something. Anyway, it looks like no concerns of this kind ever visited my head. However, there is something to think about — Thank you again.

A while ago, I found a big article speculating that PowerPoint is created mainly to support people who work for a corporation, and who have nothing to say but want to make an impression of saying something. The author was amused by the empty-minded content of most presentations and the fact that so many elements take up so much room giving no essential information. Exactly according to the previous statement. We even have a nickname for such people — “office plankton”. :-) Anyway, as I always had similar feelings, I took it pretty seriously and realized that I should permanently give up not only those commercial presentation tools but all kinds of Office products, not only Microsoft's. How could I work for corporates? Pretty easily, I must say. Moreover, I usually deliver many big presentations on a regular basis. First, I realized that I could simply show a sequence of pictures, using what I already have. You need a good picture viewer, and you can find some. Later, I came up with a similar idea (first of all, the pictures you already have) to create a more advanced show. These two noncommercial open-source products I offered to Code Project readers are alternatives, and they are similar. They show what one can create using just a Web browser and a pair of hands: [Web Presentation, an Application in a Single File, now with Video](https://www.codeproject.com/Articles/5286790/Web-Presentation) [Web Presentation, the Other Way Around](https://www.codeproject.com/Articles/5290221/Web-Presentation-the-Other-Way-Around) They provide Live Demo for both, so it would take a few seconds to find out what they are. This is one [Life Demo](https://sakryukov.github.io/web-presentation/presentation.html?demo/presentation.js), and [this is the other one](https://sakryukov.github.io/web-presentation/demo-the-other-way-around/). Enjoy! :-) Thank you.

Thank you Matthew, I'll surely will. I'll pay close attention to the potential issue next time.

Chris, If you think a bit, you will agree with me. The publication is not a state of a document, it is its attribute characterized by some event in the past. Once defined, it should remain the same for all users. Otherwise, we would have individual dates for the moment of time when Brutus killed Cesar because it was really different in different parts of the globe. We don't even know what were the time zones at that time. But people don't think this way. They record the event only by one watch, the Rome watch, and the watch existed at that time and that place. Well, okay, but at least can we return back to your words about the magic power you've mentioned. Is it possible to set the date ad-hoc to appear the same for all users? By the way, it's still a bug: when I log off, my time zone doesn't change, for it should be April 1st in my zone, but it shows March 31. How about it?

—SA

Sergey A Kryukov

Thank you for the answer, Chris. So you confirm that, with your account, you see the same that I can see with mine. Obviously, the publication date should be the property of the publication, cannot depend on the properties of a reader. Agree? Thank you.

—SA

Sergey A Kryukov

Thank you very much, but I don't think it explains the problem or the logic of the implementation. The reader's time zone has nothing to do with the date (time, for that matter) of the publication. A publication is done only in one time zone, one or another, but only one. Thank you again.

—SA

Sergey A Kryukov

Peter, Thank you for experimenting with this. Could you do the same thing: look at this article and look at the publication date. Then log off and look at the date again. Will you tell me what you see? Apparently, the publication date is just the date of some event. Once defined, it cannot depend on the time anymore. Let's say, you have a time zone of an author or a time zone of some publishing house. Any of these time zones can affect the effective publication date, but this date, when defined, cannot depend on the point of view, right? Thank you.

—SA

Sergey A Kryukov

Thank you for offering me that backdoor. But what I've reported is looks just like a bug. [EDIT] Could you tell me what date do you see on this article, and what do you see if you log off?

—SA

Sergey A Kryukov

The point is having the April 1st mark on the article permanently. I consider it as one of the attributes of all my April 1st articles. Even if I see a need for a fix, I prepare an update and wait until next April 1st to submit it... Thank you.

Sergey A Kryukov

Here is the problem: I prepared this article specially for April 1st: Markdown Calculator. I intentionally waited until today's night and completed all activities on April 1. And yes, it is listed as: Markdown-Calculator, Posted: 1 Apr 2021 Updated: 1 Apr 2021 (according to https://www.codeproject.com/script/Articles/MemberArticles.aspx?amid=2291164). And yet, when I referenced the article and clicked at the link to see how it looks for the reader non-authenticated with CodeProject, it shows: Posted 31 Mar 2021! The same goes for the page of the article: it shows the correct date, but for a non-authenticated reader it's "31 Mar". How so? Can it be fixed? Remember, having the publication marked as of April 1st is the point. Thank you. —SA
