I'm doing a DIY project that requires me to activate motors based on selections made on a custom website I'm creating on localhost. I'm really new to raspberry pi's and I really have no idea of how to connect input on a website and make it do something in the real world. My website is almost done and I'm thinking about whether it would be a better idea to create a pop up or to link it to a completely new website. If it is possible to make the raspberry pi recognize a link and notice the browser accessing the link, then I rather make a new html page for the function. If there is another way to do so like by adding a photo from the local folder and then making the pi look for the file being accessed locally. Although I have these ideas about how to do it, im really lost on how to go about it in the coding realm, im new to coding and python in general. Any help is really appreciated.
One of the ways you can do this is by using PHP to write to a txt file or database.
Then using a python code to capture the echo-ed value of in the text file or database and then manipulating the GPIOs based on this value.
If you have a single or only few motors to be manipulated then the text file way should do fine. You must also note that although this is very simple to implement, and you'll find all the necessary code online, it is far from secure.
Using a database is better if you have more no. of entities to control. It'll also be a bit more secure.

I’m building a super simple website with 5 pages and I want a CMS that allows me to change the text and the pictures in a couple of them.
In the past I used wordpress, but it has way too many features that i don’t need in this case.
I’ve been trying to learn gatsby.js so I would like to build it on that, but trying to see how to source from Netlify-CMS I started facing an overwhelming amount of information which I'm not sure I need.
Any tips?
Thanks!

Netlify has a built in CMS, and it's compatible with Gatsby! You can find examples online. It should be good for smaller sites, but for larger projects, I really like Prismic.io. Contentful is another popular one, but it's a bit pricier than prismic.
Edit: reread your comment about sourcing from Netlify. Netlify is not a "source" plug in in Gatsby. You use a local file +markdown source, and do the configuration for netlify, which adds an admin interface at an endpoint. You configure your data models in the interface, create login, etc. Then, when you submit changes, it modifies files in your connected git repo, so the local file + remark will make the data available in the graphql queries.
In the end I used Forestry.io, a good simple solution that did exactly what I needed in combination with Jekyll.
I have been fighting a losing battle against loading fonts from an embedded file for use with DirectWrite. I am writing a simple puzzle game that has a C#/XAML interface but also uses SurfaceImageSource to add some DirectX content.
I have written a WinRT component that handles all of the DirectX code, and it works quite nicely. Some of my DirectX content is text drawn using the DirectWrite API. I can draw all the text I like so long as I'm loading an installed font from the system using IDWriteFactory::GetSystemFontCollection(), etc. But, I cannot seem to find a way to load a custom font from an embedded file.
From what I can tell Metro apps are not allowed to load files from the filesystem in the same way as a traditional app. So, the IDWriteFactory::CreateFontFileReference() method that takes a normal file path is worthless to me, right? I need to load my file from an ms-appx URL.
So, I wrote a custom font loader in my WinRT component that implements the IDWriteFontCollectionLoader interface (which is a ton of work if you've never done it before btw) that loads the font from an ms-appx URL using the new StorageFile API. Now, I can load my IDWriteFontFile and I can get a IDWriteFontFace, but if I try to call any of the truly useful methods on the font face it returns E_UNEXPECTED. I can get the number of glyphs and the glyph indices, but if I try to call something like GetGlyphRunOutline() or GetDesignGlyphMetrics(), it fails with E_UNEXPECTED. Using the same drawing code that generates an ID2D1PathGeometry using GetGlyphRunOutline() works great as long as I install the font file and get the IDWriteFontFace through the series of calls starting with IDWriteFactory::GetSystemFontCollection(). I am working with a normal true type font.
So, how do I load a custom font from an embedded file into DirectWrite in a Metro app? I'm probably just missing something easy, because I am certain that other people will want to be able to load custom fonts in this way.
I have a sample project (or could prepare one easily) for anyone who can help me identify my problem.
I have loaded the two IDWriteFontFace objects side by side, and I tried to figure out what is different between the one that works and the one that breaks. What I need to see in order to find out why it is failing is opaque to me hidden behind inside the IDWriteFontFace interface. HELP PLEASE!
Question also posted here: Building Metro style games with DirectX Forum
Well, the answer is... don't write a IDWriteFontCollectionLoader! You can use IDWriteFactory::CreateFontFileReference() with the StorageFile API. I was under the impression from all of the Microsoft Conference talks I had attended that in Metro you would be unable to access the native file system directly; the way forward would be to use the StorageFile API which references resources, etc. using ms-appx URLs. I understood that this was done for concurrency and to allow the OS to insulate itself from Metro apps that would be downloaded from the store by creating a file system sandbox. I think that is accurate. But, I feel like I was led to believe that we would never be able to get native file system paths. That is NOT true. IStorageFile provides a way. Just use IStorageFile.Path. I never looked at it because I just assumed the Path property would hold the ms-appx URL that I used to create the object. Microsoft probably provided this for exactly the purpose in my problem above: calling legacy COM interfaces that require a native path.
I haven't done any testing to determine whether the WinRT framework actually sandboxes you if you try to access a native file system path outside your own app package. I'm betting that it does...
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:

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.
I am working on a web application that needs silent printing (without print dialog box) with client side printer.
After some research we found that we can make it work using ActiveX and Foxit Reader.
Currently it works great but it constraints us with IE only and we want to make it work with Firefox and Chrome as well.
I know there is no direct code to make it work, but there must a work around?
What I need is the point to start e.g. Chrome/Firefox plugins to access local printer - or make windows service that runs in background in the client side, change browser settings, use ActionScript etc.
It will also be great if someone also illustrate how Facebook access local webcam from its website it may make about accessing clients peripherals from website. Thanks in advance.
For anyone who still wants information regarding printing on Chrome and/or FireFox without the use of ActiveX, extensions or client-side scripting, please see my answer to another question similar to this.
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.
