Does anyone know about a tutorial that lets you to create something like pageflakes.com for your website? In jquery perhaps?

The creator of PageFlakes, Omar al Zabir, has created an open-source web portal called DropThings. Can't get any more similiar to PageFlakes than that!

You can use the UI library from jQuery where you'll find the draggable elements with grid. Besides that you only need to set and read some cookies that determine the position of each of the boxes.
Let's say your layout has 4 <div>s. Just save each id and position in a cookie (from javascript or by performing an AJAX request to a php/asp page).
Displaying the page is also pretty easy, you have to have 2 possibilities: when the user has a cookie defined, or else (this would be the default). If the user has a cookie defined, read it and position the <div>s like the cookie says, it shouldn't be too hard to do this.

This article on CodeProject has an excellent tutorial on how to build almost exactly what you're after, except that it uses ASP.Net Ajax. You would easily be able to substitute that with jQuery though.

.nettuts has an example all done in jquery and jquery ui. Here's the link:
http://net.tutsplus.com/tutorials/javascript-ajax/inettuts/
Goes through it all in very nice detail too. It won't be a direct copy of pageflakes, that's an exercise left for the reader but it does show exactly how to start.
HTH!

Check out ExtJS's Panels. They're what's used to build this pageflakes look-alike:

I want to make a tree view structure in React JS. I already use the package "goJS" but I am facing some issues in it. As the price of this package is very high so I can't purchase it.
The issue is that whenever I minimize the parent node it shifts to the left side and also I am unable to inspect the tree view.
I am also attaching the screenshot of my desired structure. Also I am performing some basic actions on each node and minimizing and expanding each node.
Can anybody please help out !
enter image description here
You can use MUI for your tree view structure.
https://mui.com/material-ui/react-tree-view/
Good luck.
At my job we implemented a similar view within our react front-end app using #visx/hierarchy, which is based on d3-hierarchy. I suggest you check the examples, they have some similar results than the image you linked, especially on the link types example.
Be aware that it's not an "out-of-the-box" solution, it'll require some work to obtain the exact result you want but the library will make it easier to compute the various nodes positions in a hierarchical layout.

I've just recently started looking into the details of which events fire when in what browsers when an html page is loaded, and at how to use JavaScript, especially jQuery, to leverage those events to make a page do exactly what I want, when I want.
It seems like knowledge of when and how browsers set off events and how to access them in JavaScript is a pretty big deal, but there isn't really one, good place to go and learn about it. There are thousands upon thousands of juicy tidbits which contain all the information, many of which are even grouped on certain sites (like this one), but you generally have to know what you're looking for, which prevents a lot of the "stumble upon" effect when learning about a topic.
So is there a good place to learn about all the intricacies of something like the order of events when a page is loaded, or what exactly browsers do during an AJAX call, or just about how browsers deal with an general JavaScript event?
Haven't had time to read it myself but looks quite promising:
How Browsers Work
The holy grail of Javascript (events): quirksmode.

As the title says, I am searching a very tiny rich text editor. Every editor I've seen is big and has too many features. All I need is buttons to make text bold, italic, set the font of text, set the style to a paragraph or a heading and to add/edit links. I won't have a big library for that.
I think I will need to change it a bit. I have to integrate an image upload (already existing) as a feature to add and resize images in the content.
Thank's in advance.
Check out:
TinyEditor
TinyEditor is a simple JavaScript WYSIWYG editor that is both
lightweight (8KB) and standalone. It can easily be customized to
integrate with any website through CSS and the multitude of
parameters. It handles most of the basic formatting needs and has some
functionality built in to help keep the rendered markup as clean as
possible.
If you using bootstrap. Consider to use summernote.
Super Simple WYSIWYG Editor on Bootstrap.
http://summernote.org
It depends on what you're looking for. Do you need WYSIWYG? If not, I've had success using markitup:
http://markitup.jaysalvat.com/home/
Did you look at TinyMCE?
If you're using bootstrap try Bootstrap-WYSIWYG
How about bootstrap-editor?
It's simple and beautiful. It extends bootstrap-wysihtml5 with file-uploading feature (by using jQuery-File-Upload).

Does anyone have experience with a JavaScript library for Augmented Reality?
If so, can you recommend one?
EDIT:
Not sure how to better clarify this... By Augmented Reality I mean using device webcam (laptop, smartphone, tablet) and overlapping elements over the video feed on screen. Ofen, the overlapping is done based on a marker the algorithm searches for within each frame and makes calculations about its position in space.
Hope that's enough.
Thanks.
I think this is what you might be looking for. JSARToolkit is a direct port of Flash FLARToolkit from Ilmari Heikkinen. Great tutorial you may also want to check out and a link to the Git repo.
http://weblog.bocoup.com/javascript-augmented-reality/
https://github.com/kig/JSARToolKit
You can try skarf.js, a framework that I have created for handling JavaScript augmented reality libraries in Three.js.
It currently integrates JSARToolKit and js-aruco, so you can easily switch between these two libraries to decide on the more suitable one to use.
This framework takes care of a number of things for you, including automatic loading of models when the associated markers are detected (association is specified in a JSON file). There is also a GUI marker system which allows users to control settings using AR markers.
Integration with Three.js is just one line of code to create a Skarf instance and another line of code to update.
There are videos, live demos, source codes, examples and documentation available. Check out http://cg.skeelogy.com/skarfjs/ for more info.

Does anyone have a good recommendation for a drop shadow jQuery plugin?
I've been working on a project that had every element on the page with a subtle drop shadow, we started using RUZEE to do the shadows but there was a severe performance hit when you had more then 4 or 5 shadows being calculated on the page.
I went to writing my own plugin, I call it simple shadow and it only uses jQuery to inject images in floating div's around the div you want a drop shadow. Nothing elegant but for the purpose of completing that site it worked without performance hits.
Now my plugin isn't anything special but I am still in search for a good light weight shadow plugin.
CSS 3 will support drop shadow. Firefox and Safari are already supporting the feature.
You might want to use that instead of the jQuery functionality, since it will run in browsers who have turned off javascript.
Take a look at http://www.css3.info/preview/box-shadow/ for a demo of the shadow.
The original site hosting the jQuery Dropshadow plugin has apparently gone down.
For anyone looking for it, I'm currently hosting it on my Dropbox account.
jQuery UI also provides drop shadow functionality.
The JQuery UI no longer supports shadow functionality.
try the FontEffect jQuery Plugin, sorry I can't post the link, but you can find it easily on google or jQuery plugin site.
