Is there a news feed for Amazon Linux AMI releases? - amazon-ec2

This is a pretty mundane question, sorry in advance. I'm just looking for a news feed which only contains new Amazon Linux AMI releases. It seems like the Amazon Web Services Blog feed includes these releases, but it would still be nice to have a dedicated feed for new AMIs.

There's an RSS icon on the Security Bulletins page. There are also bots that re-post these entries to Twitter and Facebook if you prefer.

Amazon Pay integration -Web

Would like to integrate the amazon pay in the application(US based). Already having paypal and pay by card option.
When referred for amazon pay sandbox, it says to register in amazon pay first. The registration process is taken to amazon seller center account other steps where business related questions are asked.
In development point of view, how can we integrate the amazon pay to our application? Is there any sample api/code available and its procedures?
Any guidance is appreciated.
The official documentation on developer.amazon.com is a good starting point for the integration. The following link points to the US version of the documentation and provides links for the integration into websites and Alexa skills:
https://developer.amazon.com/docs/amazon-pay/intro.html
It also provides links to additional developers resources such as API Reference Guides, SDKs and sample code:

Can Amazon Lex be used with other platforms (eg. Google Home)?

I'm trying to figure out which open source framework to use to start building a conversational AI for our business. We are a financial technology company so security/ privacy is just as important as ability to build features quickly.
Amazon Lex seems to be a good choice, is it possible to use it with Google Home or other voice assistants?
Also, any additional advice on which platform to use/ architecture would be very much appreciated.
Thank you!
Yes Amazon Lex can work with other services. From the Lex website:
"With Amazon Lex, you can build, test, and deploy your chatbots directly from the Amazon Lex console. Amazon Lex enables you to easily publish your voice or text chatbots to mobile devices, web apps, and chat services such as Facebook Messenger, Slack, Kik, and Twilio SMS. Once published, your Amazon Lex bot processes voice or text input in conversation with your end-users. Amazon Lex is a fully managed service so as your user engagement increases, you don’t need to worry about provisioning hardware and managing infrastructure to power your bot experience."
The answer is a bit more complex than that! Adding a bit more here as this is coming up in Google searches:
Yes, it can integrate with Facebook Messenger, Slack, Kik and Twilio SMS — those have options direct in the Lex interface for linking those services. When it comes to Google Home, you'd need to create your own bridge between Amazon Lex and Google's Actions SDK.
So you'd take what the Google Actions SDK hears someone say when they speak to their Google Home (the fulfilment text), and then need to pass that onto Amazon Lex. To do that, you need to use Amazon Lex's postText or postContent functions (Lex Runtime docs on that). I haven't done this myself just yet, but I've heard of others doing similar and spotted this Stack Overflow post explaining it in a bit more detail when looking for an example.

Are there any tutorials for putting an app on Heroku

I have my app fully deployed for free at https://blooming-summer-8571.herokuapp.com/ but want to start paying for hosting for my own custom domain. I have also bought a domain name that I want to put my app on. What are the best resources or even google search key words that will help me do this through heroku?
Your best bet is to go through the heroku dev center located at:
https://devcenter.heroku.com/
There are topics from the very basics to more advanced ones. You're looking for the custom domain setup, instructions for which can be found here: https://devcenter.heroku.com/articles/custom-domains

Hosting web site images: Flickr PRO, Amazon S3 or...?

I'd like to save some of my site monthly bandwidth allocation and I'm wondering if I can use Flickr PRO or I should rely on Amazon S3 as an hosting service for my web site images. (My Web Application allows users to upload their own pictures and at the moment it's managing around 40GB of data)
I've never used Amazon's services and I like the idea of using Flickr REST Api do dynamically upload images from my webApp.
I like also the idea of having virtually unlimited space to store images on Flickr for only 25$/year but I'm not sure if I can use their service on my web site.
I think that my account can be banned if I use Flickr services to store images (uploaded by users of my website) that are not only for 'personal use'.
What's your experience and would you suggest other services rather than Amazon's S3 or is this the only available option at the moment?
Thanks
edit: Flickr explicitly says 'Don’t use Flickr for commercial purpose', you could always contact them to ask to evaluate your request but it sounds to me like I can't use their services to achieve what I want. S3 looks like the way to go then...
Even though a rough estimate of what I'm going to spend every month is still scaring
5000 visit/day
* 400 img/user (avg 50kB/image)
* 30 days
= ~3TB of traffic
* 0.15$/GB (Amazon S3)
= 429$/month
is there any cheaper place to host my images?
400 images per user seems high? Is that figure from actual stats?
Amazon S3 is great and it just works!
A possible cheaper option is Google. Google docs now supports all file types, so you can load the images up to a Google docs folder, and share the folder for public access. The URL's are kind of long e.g.
http://lh6.ggpht.com/VMLEHAa3kSHEoRr7AchhQ6HEzHVTn1b7Mf-whpxmPlpdrRfPW216UhYdQy3pzIe4f8Q7PKXN79AD4eRqu1obC7I
Add the =s paramter to scale the image, cool! e.g. for 200 pixels wide
http://lh6.ggpht.com/VMLEHAa3kSHEoRr7AchhQ6HEzHVTn1b7Mf-whpxmPlpdrRfPW216UhYdQy3pzIe4f8Q7PKXN79AD4eRqu1obC7I=s200
Google only charge USD5/year for 20GB. There is a full API for uploading docs etc
I love amazon S3. There are so many great code libraries (LitS3) and browser plugins (S3Fox) and upload widgets (Flajaxian) that make it really easy to use.
And you only pay for what you use. I use it a lot and have only ever experienced down time on one occasion.
Nivanix is an s3 competitor. I haven't used them, but they have a bit more functionality (image resizing) etc.
Edit:The link about Nivanix is dead now(2015/07/21), because Nivanix was dead.

How to evaluate hosted full text search solutions?

What are the options when it comes to SaaS/hosted full text search? How should I evaluate the different options available?
I'm looking for something that uses Lucene, solr, or sphinx on the backend, and provides a REST API for submitting documents to index, and running searches.
I could build my own EC2 AMI, but I'd have to configure EBS and other stuff, monitor it, etc.
Websolr provides a cloud-based Solr with a control panel. It's in private beta as of this writing, but you can get the service through Heroku.
Another hosted Solr service is PowCloud, also in private beta, which seems to offer strong Wordpress integration.
SolrHQ: another beta service providing a hosted Solr solution, with Joomla and Wordpress integrations.
Acquia Search offers Solr integration for Drupal sites.
If you decide to build your own EC2 instance, the SolrOnAmazonEC2 wiki page might be useful. Or you could just get LucidWorks Solr for EC2, which is probably the easiest and fastest way to get Solr on EC2.
Engine Yard provides a cloud-based Sphinx service.
Indextank is a hosted real-time full text search solution. It's pretty simple to set up (you can get an index running in a couple of minutes) and it's very powerfull (Reddit runs over IndexTank). It provides Java, Python, Ruby and Php clients as well as a Rest API specification. There's an awesome support service (including live chat). You should give it a try.
Another option, particularly for UK people is http://www.netaphorsearch.com/ . I should point out I own Netaphor Ltd. We support the Solr REST API but also have a PHP connector so that you can get up and running very quickly.
Have a look at Artirix - UK company but also in the US http://www.artirix.com. I know they power some sites such as Globrix.com in the UK based on SOLR and have a bunch of other products for crawling and data processing
My five cents
http://indexisto.com/
Offers free hosted Elastic Search if you are ready for advertisement in search results. But anyway you can start with free, and switch to no ads paid account.
It's also not just hosted Elastic Search, but ready to ase Ajax search box (that really impress) to embed to you site (mobile and tablet adopted), and some useful features like statistics, image resizing. There are several options to fill the index with documents - crawler, API and DB connector
Another option for lower-volume websites is Midwestern Mac's hosted Solr search (I am the owner of Midwestern Mac, LLC, just fyi).
Although it's not too hard (if you can use a command line respectably well) to provision your own server on a VPS somewhere...
