I found this free PWA https://www.the-qrcode-generator.com and now wonder how I could do one such myself.
Since I couldn't find any access to its source code I wondered if it'd be difficult to reverse engineer.
I'm interested in building a PWA with QRCode functionality.
This one was created with AngularJS v1.3.20. You can find the source in your console windows under Sources tab. You can easily beautify the code inside the window to make it readable.
If you want to know how they organized their rest API, the browser network tab will help a lot, just filter by XHR and examine all the call from the front end to be.
The front end is very hard to revers engineer, because most sites are served as minified bundles, so you can't see the original code.
You can however find some other information about what they used to build it, for example in the html source you can see some ng-* tags, which indicates that this is angular, you can also see that body has attribute data-ng-app meaning this is angularjs and so on.
For the QR logic you can see that there are no back end calls, meaning that it is written entirely in the client. I would search for already available solutions for that.

Do you know any software or tools that can be used to detect when people are stealing content from our website?
Today we are only able the do something about the duplicate content, when we find it manually. There must be some kind of tool or service to use, to detect stolen content?
I'm a part of the project called whocopied.me where you can insert a little javascript snippet and you have a dashboard that helps you with an overview.
We created a little introduction to show it in action

If you are using Wordpress, we created a simple plugin for you to install - no requirement of understanding HTML :-)

We are using GWT and take advantage of History framework. Everything works fine in application, but some of our clients are trying to put hyperlinks to our application in their PowerPoint presentations. But there is known problem in PP2007 with hash signs ("#") in hyperlinks which makes them unusable.
So is there any way to change separator character used in URLs generated by GWT Hisory framework to something other than hash?
Or is it possible to intercept new URL generated by GWT history and modify it before browser's adress bar is updated with it?
I don't think you can/should change the hash sign. Mainly because this sign does not come from GWT but from HTTP specifications. You can read the part on hash fragments in this doc for a good explanation. The main point being that adding a # sign to a url will not cause a full browser refresh. This is why this sign is used for ajax and GWT's history.
If you still want to intercept new URLs, you should probably add a ValueChangeHandler to your History, and then use Window.Location.getHref() and Window.Location.assign() to change the URL. But that's like using History to do something it doesn't do, so you're better off implementing your own History management system.

Basically, you can only do this in a browser that supports HTML5's pushState and onpopstate. This rules out Internet Explorer, and unfortunately those people using PowerPointer are likely to also use IE, so basically you're doomed.
My problem is very similar to the one posted here:
http://www.utteraccess.com/forum/Plotting-Addresses-Maps-t1968130.html
except that thread never found any solutions. Basically, I'm working on an Access form that has a datasheet as a subform. Upon clicking a button on the main form I'm trying to make it so that a browser window opens up and, using the address columns from the spreadsheet data in the subform, plot all the address markers listed. I've looked up a lot of ways to attempt this but I've yet to find a way that seems to work.
I'm not even sure if it's possible to plot multiple markers on Google Maps, but according to research (and after trying it myself) it seems like it isn't, although I don't want to rule it out entirely because I'm still not 100% sure. However I know both Google Earth and batchgeo.com do allow this. I still want to try and do this on Google Maps, but if that doesn't work I want to try to do it using batchgeo.com and if that still doesn't work, then Google Earth (I don't want to make the user download external software if possible).
If it helps, from what I've read API's seem like a useful tool, though I'm not sure how to apply it to an Access form, it seems more like a way to embed to already existing websites.
I'd really appreciate if someone could help me figure out how to approach this problem!
Maybe this would help?

It is Excel but should be translatable.
Here is another example, this time using Access:
http://www.utteraccess.com/forum/Google-Maps-Multiple-Mar-t1973499.html
...from what I've read API's seem like a useful tool, though I'm not
sure how to apply it to an Access form, it seems more like a way to
embed to already existing websites.
You're right. There's no way, that I'm aware of, to embed a Google Maps object in a form (like an ActiveX control). Microsoft MapPoint is a software product that lets you do Map integration by way of an ActiveX control (no need to use HTML and/or javascript).
What I usually do on a project like you're working on is I get my HTML page working the way I want it to, outside and independent of MS Access. You should be able to program and test the HTML file locally without having to use an actual web server. Just use something like NotePad++ or Sublime Text Editor 2 to write your HTML and Javascript and then open the file in your browser to see if it works. I'm quite sure you'll need to use Javascript in your HTML page to make this work. That's what the Google Maps API is all about.
After you have your webpage working, then you will have to go into Access and write code to create that web page on the fly with the address data for the current data set. You can just write it out to the Windows Temp folder and then open your browser control that that web page.
Julian Knight's answer links to more specifics on how to create the HTML page on the fly. It looks like gobble-de-gook, mostly because it is. Outputting HTML/Javascript/CSS from VBA is far less than optimal. This is why you troubleshoot it outside of Access, as much as you can.
Please forgive me if this answer is somewhere else on this site or online. If it is, I sure haven't found it in the past several days of searching.
What I am hoping to find is an "accurate" method of detecting a browser and redirecting to a simple, static page if not a recent browser.
The samples I have found until now often have not provided an accurate representation of the actual browser being used. For instance:
When testing with Navigator 9, I'll get a message that I'm using Firefox 2
When testing with Maxthon 3, it reports I'm using IE 9.
My site displays correctly in all the current browsers I've been testing it with. But I wish I could have a basic static page for those .01% who still are using an old browser for whatever reason. They could still get some basic information from my site, as well as encouraged to update to a more current browser.
If anyone has any useful suggestions, I'd greatly appreciate them.
Thanks so much.
Cheers,
David
Browser detection is never perfect, for a variery of reasons. If you are using jQuery, you should look into jQuery.browser.
I'd try to detect the browser on the server side and do an HTTP redirect if the browser is something non-standard. Most decent frameworks have functionality to detect the browser from the user agent string. Again, this is not perfect, mainly because of the data browsers report. Also, if Maxthon reports it's IE, that's because it is based on IE and therefore the layout engine should be the same.
So you either
support a small number of browsers and cater for their quirks, sending all other browsers to a basic page (this sucks for future versions of browsers because they might be standards-compliant but they will still display your very basic page), or
you have a standards-compliant page for all browsers and then you define alternatives for the ones that give you problems.
I'd go for the second option. It usually all boils down to one version for all browsers, and a number of hacks for various versions of IE. Also, remember to avoid padding in your CSS and use margins instead.
In the end, you probably shouldn't be testing for browsers and version numbers, but supported features. Try using Modernizr.
The $.browser property is deprecated in jQuery 1.3. On jQuery support site, they strongly recommend to use the detection feature (JQuery.support) instead of the jQuery.browser property.
Actually, this has been answered already in another question, please check here How can you detect the version of a browser?
As a side project I tutor grandparents and other computer novices in Computer & Internet 101, from physically using a mouse to dealing with e-mail/searching/etc. Web development isn't really my area of focus - I do have reasonable HTML/CSS/Javascript etc skills, so I can throw together a decent-looking simple, static site - but occasionally I get asked to put together extremely simple websites for these people, that they can update themselves; that is, edit text-based content without giving Grandpa a heart attack by making him come face-to-face with HTML/Javascript.
I've waded through a mile-long list of CMS software - largely culled from the many other similar questions on SO - but they've all got something ruling it out: hosted, restricts the design (can't use w/existing CSS, looks "Word-press-y", etc), not free/FOSS, etc. I wonder if "CMS" is even the right word for what I'm looking for. What I need is a simple text editor for the client: that is, something that will give the client a text box of some variety, let them edit it, and update the content with that info. They can't mess with navigation, add new pages, change anything other than text. If it was really fancy, they could upload a picture.
I was planning to do this just with a couple of password-protected php forms, but thought I'd ask if there's anything already out there that might provide this functionality? Any suggestions on building my own version of this, in PHP or something else?
What I'm really interested in is:
1) the simplicity/customize-ability of the admin interface (or lack of admin interface, if the client could somehow edit directly in the page), and
2) ease of set up for me (not getting paid much if at all for this, don't want to wade through three million plugin options to figure out how to get some unwieldy, high learning-curve framework to do what I want).
Try pulsecms.
Here is another very simple CMS that has JQuery and modernizr , HTML5 Boilerplate and TinyMCE.
I have my wife setup with Windows LiveWriter
http://explore.live.com/windows-live-writer?os=other
This means that she just builds her articles as if she is using a word processor (almost exactly the same) and then just uploads the article to her blog. I use Blogengine.net to host the blog on a Godaddy hosting solution.
Blogengine comes with built in support for LiveWriter and only required that you input the address, username and password in.
I understand this is an old post, but i hope someone find this of interest.
You could give the users the instruction to upload text files to the site, and the have the HTLM/PHP/ASP pages load the context of such .ts files.
Each web page should have a specific named .txt file associated.
