similar to: storing s3 files for processing in rails/tmp/s3 ?

Hi there, I''d like to use RMagick to watermark an image in the tmp directory before Attachment_fu saves it to Amazon S3. I took a look at the callbacks available in attachment_fu. There''s an ''after_attachment_saved'' method but this would be too late, and a ''before_thumbnail_saved'' but this is no good because it''s for thumbnails. I

Greetings! I''d appreciate hearing from anybody who''s had experience with any of this. I''ve got a Rails app that currently deployed on EC2 with MySQL and am readying to move from a dev / prototype model to a full-scale production model. Right now I''ve got a single MySQL instance. I''m getting ready to move that to a master-slave setup. I''m

Greetings, I just found Puppet last night. Really wish that the discovery had been made last month before tons of late night messy bash scripts were written to help boot up an ec2 image.... With very little effort Puppet is now installed on my desktop as a server and one of my staging servers is able to call into the puppetmaster to run a very very simple manifest. So far I am super-

Hi, I need to be able to encrypt files before storing them on S3, and then decrypt them when accessing them. The files will be images, documents, PDF, etc. I am using Carrierwave to handle the file upload and storage. I am storing them in Amazon S3. Has anyone done this, or have any ideas how this would be achieved? Thanks. -- You received this message because you are subscribed to the

So we are setting up a file upload system for our web app. Files will be uploaded to Amazon S3, and videos need to be converted to ffmpeg. We have had problems with uploading of large files timing out, and it was suggested to us to use http://github.com/elcgit/s3-swf-upload-plugin for uploading directly to S3. This would fix the timeout, but then could I use ffmpeg to convert the file once it is

I was wondering if anyone here has seen a similar error to this... >From mongrel.log /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/ transactions.rb:85:in `transaction'': Transaction aborted (ActiveRecord::Transactions::TransactionError) from /usr/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/mongrel/ configurator.rb:293:in `call'' from

I''m looking at using EC2 for hosting deploying my Rails site. The reasons for the decision are these: I want something that will work for 10 users, but with capacity to expand to 10,000,000 if needed. EC2 starts at $15/month (before bandwidth) which seems reasonable even for a site in its infancy. And the costs seem to scale up well, along with the capacity. There isn''t the

Hello: This is the result of some recent work on managing Amazon EC2 clusters using puppet. http://reductivelabs.com/trac/puppet/wiki/AmazonWebServiceRecipes I''m a rookie so any coaching is appreciated. Thanks, Brad

Hi, I store files on S3 as the id of the file in my appliction. IE my file with id 20 will be stored on S3 as 20. When I download the file I want to look up the file name in the database and then pass it off to the user. Is there any way I can use redirect_to and pass the S3 url and then give it the filename, so the user doesn''t get 20. Does this make sense? Thanks, David -- Posted

For various reasons, I made a git branch and installed Paperclip in place of attachment_fu. Paperclip works great except that images seem to have lost some quality; edges have gone a little too jaggy to be able to drop attachment_fu just yet. After a post on the Paperclip Google Group, someone suggested the :convert_options could be passed additional attributes, like ''quality'',

Buenas a todos. Ya sé que con sparkR o sparklyr puedo leer fácilmente ficheros con formato parquet, pero ¿hay alguna forma de leerlos sin tener que arrancar spark? Mi situación es que tengo unos ficheros en formato parquet en s3 y quiero leerlos desde una instancia pequeñita de amazon EC2 que quiero mantener sin instalarle spark. Estoy bicheando la librería https://github.com/cloudyr/aws.s3 y va

Hi All, I am a newbie. I am following http://railscasts.com/episodes/383-uploading-to-amazon-s3?view=comments to upload file. I am able to upload single file with carrierwave. But I got 403(Forbidden) error when I try to upload multiple files using jquery file upload. When I try to upload single/multiple file I get alert box saying failed to upload and in console it says "Failed to

This has nothing to do with printing or dispatch per se. It is the result of an internal register (R_ReturnedValue) being protected. It gets rewritten whenever there is a jump, e.g. by an explicit return call. So a simplified example is new_foo <- function() { e <- new.env() reg.finalizer(e, function(e) message("Finalizer called")) e } bar <- function(x)

Hola Carlos. spark_read_parquet es de sparklyr y necesita un sparkcontext inicializado para leer el fichero de parquet. El mié., 4 oct. 2017 22:11, Carlos Ortega <cof en qualityexcellence.es> escribió: > Hola José Luis, > > ¿Has probado directamente con "dplyr"?... > > spark_read_parquet >

Hi I''ve done a small rails application for file management on Amazon''s new service, the storage webservice ''Amazon S3'' (at this time just upload, list and delete methods are implemented). Maybe someone find it useful as example. The source code and a little more information can be found here: http://caffo.backpackit.com/pub/502395 Best regards Rodrigo Franco

I did some searching in the mail archives and didn't see any discussion of integration with AWS, so I wanted to through out my thoughts/plans and see if it has been done before. I am setting up my own personal website on EC2 along with an email server, and I really don't like the idea of using the disk drive as permanent mail storage. EBS is too small instance storage is ephermeral.
