I have two chromium-based browsers each having its own benefits, I want both of them in one. Is it possible?Any help?
I need anonimity(epic browser) and torrent download feature( torch browser) in one browser, so I thought merging these two would be a good idea. Getting thier source code and modifying it to create our own. Is it feasible?
Thank you.

I need to detect programatically if a website has an e-commerce platform/system
I don't need to know which one, I just need to know if the website has one.
(I have a big list of websites so I probably need to scrape them)
any suggestions on how I could do this without using external websites (like rescan.io/builtwith/etc) would be greatly appreciated!
thank you!
You can use a package called Puppeteer which is used to do web-scraping in node.js.
I don't know what platforms you are trying to look for, but I guess you could try something like giving the list of websites you want to check to a node.js process and ask Puppeteer to scrape them all. Then you look at the content you get back and for example look for Shopify's CDN in the tags or check the tags for keywords.
You will definitely need to check each different platform like Magento or Shopify for unique source code that clearly sets apart the framework you are looking at from other tools.
Now, I'm looking for the solution to generate pdf (invoice with barcode, etc..) from template(html, css) in nodejs environment. I found there are several ways to do that such as wkhtmltopdf, phantom.js & handlebars.js, html-pdf. What I'm concern is which is the best way to solve this problem.
Also, I have look at jsPDF, an client side generation, but it seem not suitable for production right now.
So, Anyone have used one of these library in production, please give me an advised.
Many thanks !
UPDATED:
Headless chromium is now ready for use.
Have some limitation (e.g: custom header, footer), but work great in almost cases.

UPDATED: 4/2019
Now, Puppeteer is a major library for generating pdfs
https://github.com/GoogleChrome/puppeteer
If the invoice is on a static webpage, PhantomJS will allow you to generate a PDF . Here are a link to the screen-capture section of the docs. It shows you how simple it is do perform this :)
Very random and annoying problem with IE6. We keep our common JS files on a resources server so we only have to update them in one place. As well as our custom classes we also keep our build of mootools and more on the resources server and link to it in the head of our sites.
This is fine in all the browsers accept IE6. In IE6 it seems to not loads the core quick enough from the external link before trying to process the mootools code in my site.js file. It will go wrong on the first line "windows.addEvent".
If i put a mootools core in a folder where the site is though its fine. Does anyone know why it might be doing this and if so a way around it, but still keeping the files on the resources domain?
Thanks
Tom
#neil . Yeah exactly. Quite frankly i didn't want to be rude but the first two responses were a waste of their time and mine. Someone correcting a typo and someone else saying not to bother supporting a browser that still has 9% share of the market, quite brilliant.
#Dimitar Thanks for your response. I can't change the event to load unless you mean in native JS because no mootools will work. I don't like mixing the native JS when i'm using a framework if i can help it. Never heard of "defer" though, i will def try that. Thanks for your help.
IE6 probably pipelines the download as an extra host gives it the ability to do it in parallel.
perhaps you can either try adding defer='defer' for IE6 for your chunk of code that relies on mootools or change the event from domready to load instead (also for IE) (I tend to use the latter)
I know that there are even some web-resources exist which allow you to get a preview of a web-site 'as it looks in a certain browser'.
I only need view from any browser as an image. Is it possible to get that image without people involvement? Can I get it without system programming, just by means of pure java/python/asp.net?
UPD: http://browsershots.org/ is an example of described web-resources.
The tools I know of that does this - really "just" launches a browser (programatically of course) and takes a screenshot of the contents of the browser and saves this in an image.
I think no matter what you do, you will have to find a way of doing something like this. If you by system programming are refering to OS API calls, then I think you will be out of luck. You might be able to get a third party library that can do this for you, but then that library will simply be making those system calls instead.
I see now others have posted links to places that might prove themself useful to you as well. Without having looked at the links, that would probably be the easiest and best way to go.
Good luck
I believe what you're looking for is browsershots
There are some websites that let you do this.
Try BrowserShots
PageGlimpse is a service
providing developers with programatic
access to thumbnails of any web page.
It has API based on REST protocol and some documentation.
You have a lot of things doing this for you. Take a look at stw for instance.
If you're using .NET, it is possible to do this using the DrawToBitmap method of the WebBrowser control (example here). However, as you'll see by the last comment on that example page, it doesn't work with Flash, and it's a bit 'temperamental' with sites that use complex Javascript for rendering.
I think your best bet is to do as others have said and use a third party thumbnail provider. I haven't used it, but http://www.thumbshots.com/ looks good.
I want to display a message to users with unsupported browsers, as opposed to having the site fail in an ugly manner.
What's the best way to do that?
GWT also provides browser detection using the .gwt.xml file. Have a look at this:
http://code.google.com/p/google-web-toolkit-doc-1-5/wiki/DevGuideDeferredBindingReplacement
It's an interesting solution, but I'm not sure if it's the best solution in your case. It could be very useful for creating a simplified version of your application which would automatically be loaded in unsupported browsers.
The GWT team does not provide a list of unsupported browsers, only supported browsers, and it's a vague list at that "most recent versions of Internet Explorer, Firefox, and Safari. (Opera, too, most of the time.)".
If you have a good idea yourself of what browser/version won't work you can use this code:
public static native String getUserAgent() /*-{
return navigator.userAgent.toLowerCase();
}-*/
to learn what browser is being used and perhaps cook up a work-around.
On the other hand, browser rendering of web pages can fail in many subtle ways ranging from mildly annoying to catastrophic, and there is often no way to know where your page falls on that scale. One of the major reasons for GWT is that you can stop worrying about this sort of thing. At least until it happens.
If you want to make it simple and stupid, check with some javascript code in your main html file, before GWT is loaded. Novertheless, I would rather trust GWT to handle things more or less quirky. You could also just recommend chrome or firefox.
I realise this is an old question, but I had the same problem, and wanted to share a new solution for it.
Today with GWT2.7 "obsolete" browsers try to download undefined.cache.js. This obviously fails and the client is stuck forever.
You could patch GWT itself setting fallback compile steps, but the easy solution is to simply provide a (manually crafted) undefined.cache.js and place it where the other generated files are.
Inside you put this one line:
xxxxxxx.onScriptDownloaded(alert('This browser is not supported anymore.\nPlease upgrade to a more recent browser.'));
where xxxxxxx is your module basename (from xxxxxxxx.gwt.xml).
