For the last 5 or so years if I have needed a QR code I have used the google APIs, yesterday for around 4 hours this service stopped. On investigation I found the service is now deprecated and a link to use Google Charts instead? I can not find any qr codes though?
So my question is does anyone one know if Google maintaining an API to generate QR Codes? If so where can the documentation on this be found. Or has their been a definitive statement from Google to say they are not supporting it going forward.
The google API is really easy to use and has been reliable until now, example below.
https://chart.googleapis.com/chart?cht=qr&chs=300x300&chl=stuff
I found this post from a few years ago, I am not working in php sadly.
Is there an alternative to Google Chart API QR Generator?
I don't think the dynamic Google Charts Javascript library supports QR codes. There are many alternative services that have been posted since its deprecation.
One such service is QuickChart, which is hosted at https://quickchart.io/ and also open source.

I have been struggling to get any XPath technique to work on octoparse and similar software. I'm now trying google sheets from reading posts here and can't get it to work either.
Input: A slideshare presentation url (eg https://www.slideshare.net/carologic/ai-and-machine-learning-demystified-by-carol-smith-at-midwest-ux-2017)
Intended output: Slideshare embed url (in this case: https://www.slideshare.net/slideshow/embed_code/key/wZudqqTdctjWXA)
I think this would be the way to get the output using google sheets: =importxml(A1,"//meta[#itemprop='embedURL']/#content")
It is not working for me (failure to fetch url). With Octoparse etc I just got a blank value.
I'm being daft here, no doubt. Any help would be useful.
It doesn't work because slideshare is owned by LinkedIN, and they have put in a lot of effort to ensure they cant be scraped, including google sheets. Before it was possible, but I believe they eventually caught on to the work around.
I want to generate chart with respect to Clicks Vs Date.

How can i generate chart like attached screenshot.
Thanks in advance
So there are many ways this could be accomplished. From my experience, I have actually done similar reporting utilizing PHP and Google Visualization charts. You would probably want a single Area Chart: https://code.google.com/apis/ajax/playground/?type=visualization#area_chart. I'm sure you can get it to look pretty close to the Google Analytics report you displayed above. You are going to have to utilize some javascript skills, but they are at most beginner level if you follow the samples provided by Google.
I'm developing a new app using jQuery Mobile and Phonegap.
In my case, I use the geolocalization for showing every interesting point around the users. Cordinates and data are loading by Ajax and json.
Now i try to use a gmap (here), but the prestations (speed loading in particular) are slow and very far from native experience.
Which is the best metod for use maps with Phonegap?
Fastest solution I so up today is Google maps v3 API. I have used it inside several of mine apps and it works fine, of course feeling is not fully native like but you will never be able to achieve it in combination with jQuery Mobile. Framework used in that example is Google maps v2 API and it it's deprecated last few years.
V3 API is done from the scratch so it works much faster then V2, not to mention it has a full support for HTML5 browsers.
Few working examples can be found in my other answer HERE.
You can make it even more faster if you initialize map during the application initialization. In this case map will be ready and available as soon as map page is shown. Feel free to ask if you need a help with implementation.
Ok, I trying this example of Google Maps V3 here, and the map on Phonegap are finally fast.
I don't recommend gmap UI on Phonegap.
How to get started with CodeIgniter and Google Maps API.
I've got a CodeIgniter library specifically for this purpose. You can find more information about it here:
http://biostall.com/codeigniter-google-maps-v3-api-library
A few demos of what can be acheived using the library:
http://biostall.com/demos/google-maps-v3-api-codeigniter-library/
Give me a shout if you have any questions or need any help :)
Enjoy!
CodeIgniter is a backend (server-side) framework. Google Maps API is a frontend (client-side) library. There isn't really any specialized knowledge you need to know about CodeIgniter to get Google Maps working, other than being able to render a view. The question is somewhat flawed in that you assume one depends on the other, when in reality, they are very much decoupled.
The question is similar to how do i get jquery working with codeigniter?...
Reading the CodeIgniter documentation would be a start to understanding how to echo HTML and JavaScript to the browser. The rest is almost entirely client-side JavaScript programming.
I would like to write a web app that uses Dropbox for cloud storage.
If I understand correctly, I should use the Restful API to achieve that.
This documentation exists and is quite good but being a newcomer to Restful API I would love to see and play with a simple example that works with this API.
My questions are:
Am I right to assume that Rest API is the way to go?
Is there a quick and easy example (Maybe a live example) to get me going?
Thanks!
as you tagged your question with "ajax", i presume you want to do this entirely client-side (except for some proxy-code to be able to make requests accross domains)? I haven't tried it out myself, but there's dropbox-js on google code which will at least give you some ideas (and if the Dropbox API didn't change too much since June 2010 it might even work out of the box)?
Update: there's no "download", but you can browse the source code of trunk here.
Here's a lengthy article on the matter
