• How to process images with paperclip on Heroku?

  - by Yuri

  I use Heroku for my app. I want to auto-orient image and then to resize it. So I do: class User < ActiveRecord::Base Paperclip.options[:swallow_stderr] = false has_attached_file :photo, :styles => { :square => "100%", :large => "100%" }, :convert_options => { :square => "-auto-orient -geometry 70X70#", :large => "-auto-orient -geometry X300" }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":attachment/:id/:style.:extension", :bucket => 'mybucket' validates_attachment_size :photo, :less_than => 5.megabyte end It does not work with error: There was an error processing the thumbnail for stream.20143 What am I doing wrong?

The application have a good internet connection and there is no problem reaching the app server-side api. I see in analytics that lots of startups and click-events the past few days are lost, even I know the traffic is normal since i can see statistics from the the server api. In the analytics reports I see a day by day under-reporting. So the problems seems to be spreading/growing to all the devices using this application. Im wondering why google does not answer this in their mail-groups - several people have complained about this...well, well... I found this thread relevant: http://stackoverflow.com/questions/682560/java-net-socketexception-broken-pipe But, I'm still not sure if there is anything I can do to fix it or not. If there is nothing I can do to fix it, I guess its not my fault that it got broken. But i got a feeling it is, since the problem got dramatically worse on the last deploy to Android market. Anyone else with experience on Google Analytics for android ?

• Silverlight 3 Offline Mode

  - by GWLlosa

  Has anyone found that the userbase is more reluctant to install Silverlight 3 Apps in offline mode because they have no control over "where" the app is installed to? I've had a few issues of a similar nature in the past, with 'power users' getting upset that they can't specify install directories. Are there any workarounds? Any way to get the Silverlight offline installs to prompt for specific install locations and the like? The specific reason given is that users want to install apps to remote storage, like a USB stick or something.

• Would the MSFT Report Viewer (rdlc) Work with MVC

  - by Mike Thomas

  I am interested in learning MVC, and have experimented with a couple of the sample apps. As a project, I'd like to move part or all of my own office app to MVC. An important part of this app, and of ALL of my apps for customers, is the printing of invoices, purchase orders, inventory lists and so forth. In fact, one of their main criteria for judging what we do is the appearance of these documents and their incorporation into the app in a practical, intuitive way. It's impossible for me to get by without a report writer. The MSFT report viewer used to produce rdlc reports has been sufficient, and even comes up better than the competition in a couple of key areas. Does this control work with an ASP.NET MVC application?

• Interval tree algorithm that supports merging of intervals with no overlap

  - by Dave Griffiths

  I'm looking for an interval tree algorithm similar to the red-black interval tree in CLR but that supports merging of intervals by default so that there are never any overlapping intervals. In other words if you had a tree containing two intervals [2,3] and [5,6] and you added the interval [4,4], the result would be a tree containing just one interval [2,6]. Thanks Update: the use case I'm considering is calculating transitive closure. Interval sets are used to store the successor sets because they have been found to be quite compact. But if you represent interval sets just as a linked list I have found that in some situations they can become quite large and hence so does the time required to find the insertion point. Hence my interest in interval trees. Also there may be quite a lot of merging one tree with another (i.e. a set OR operation) - if both trees are large then it may be better to create a new tree using inorder walks of both trees rather than repeated insertions of each interval.

• Comparing two Oracle schema, other users

  - by Igman

  Hello! I have been tasked with comparing two oracle schema with a large number of tables to find the structural differences in the schema. Up until know I have used the DB Diff tool in Oracle SQL Developer, and it has worked very well. The issue is that now I need to compare tables in a user that I cannot log into , but I can see it through the other users section in SQL developer. The issue is that whenever I try to use the diff tool to compare those objects to the other schema it does not work. Does anyone have any idea how to do this? It would save me a very large amount of work. I have some basic SQL knowledge if that is whats needed. Thanks.

• Cannot create a row of size 8074 which is greater than the allowable maximum row size of 8060.

  - by Lieven Cardoen

  I have already asked a question about this, but the problems keeps on hitting me ;-) I have two tables that are identical. I want to add a xml column. In the first table this is no problem, but in the second table I get the sqlException (title). However, apart from the data in it, they are the same.

• Odd Drag and drag bug in nested attributes Rails

  - by Senthil

  I've got this weird bug when trying to use drag and drag for two models (one nested within another). I've a category model which has many apps. In my category index page, I tried use "content_tag_for" to sort categories and apps within each category. But for some odd reason only the first element has drag, drop enabled. I can drag and drop categories all I want, but I can't drag the app in the second category, just the first category. Copy and paste gets ridiculously hopeless with HAML, so here's a Pastie instead. I made a sample app on heroku for you to check out here. Drag and drag work for both category and app, so I'm guessing it has to do something with the ul or li. Any help is appreciated. Thanks.

• One to many too much data returned - MySQL

  - by Evan McPeters

  I have 2 related MySQL tables in a one to many relationship. Customers: cust_id, cust_name, cust_notes Orders: order_id, cust_id, order_comments So, if I do a standard join to get all customers and their orders via PHP, I return something like: Jack Black, jack's notes, comments about jack's 1st order Jack Black, jack's notes, comments about jack's 2nd order Simon Smith, simon's notes, comments about simon's 1st order Simon Smith, simon's notes, comments about simon's 2nd order The problem is that *cust_notes* is a text field and can be quite large (a couple of thousand words). So, it seems like returning that field for every order is inneficient. I could use *GROUP_CONCAT* and JOINS to return all *order_comments* on a single row BUT order_comments is a large text field too, so it seems like that could create a problem. Should I just use two separate queries, one for the customers table and one for the orders table? Is there a better way?

• What can't I build in Silverlight?

  - by Refracted Paladin

  First, I know that Silverlight needs to be embedded in a website, usually an asp page. I understand I need a delivery boy. My question is this; What types of apps/projects are so filled with technological hurdles as to make them ridiculous to do in Silverlight versus ASP.net? I know that with perseverance and flexibility I can probably make EVERY app in Silverlight, in some version or another, but which ones would be blatantly simple in, say ASP.net(or even WPF) but quite complicated in Silverlight? Basically what I am asking is if there is any reason I shouldn't consider Silverlight my first stop for every problem, obvious exceptions not with standing(a service or console). For me specifically, at this point, I am only building in house apps.

• Which version of MSXML should I use?

  - by Cheeso

  Seems like this would be a common question, though I could not find it on SO. Which version of MSXML should I use in my applications, and more importantly, how should I decide? There is MSXML3, 4, 5 and 6. I recently posted some code in calling-wcf-service-by-vbscript that used MSXML v4. AnthonyWJones posted that I shouldn't use 4, but instead 3 or 6, but probably 3. Certainly not v5! Why? I'd like to know more about the criteria for selecting the version of MSXML to use in my apps. Bonus question: Does anyone have a summary of the differences between the various versions of MSXML over time? Summary so far: MSXML6 Should be first choice. was released in 2006, and includes perf and compliance fixes. Use this if you can. It's good. There are no merge modules; to bundle the MSXML6 runtime with your app, MS suggests packaging the MSXML6 msi file. MSXML6 is an upgrade from MSXML3/4 but does not replace them, because it discontinues some features. You can get the MSI here. MSXML3 Second choice. Most widely deployed version. Originally shipped in March 2000. Actively maintained, no new features. Currently supported, if you are on SP5 (shipped in 2005) or later. SP7 is current (also from 2005). MSXML5 was released only as part of MS-Office. Currently supported by Microsoft, but only as part of Office, not for building apps. Don't build apps that depend on MSXML5: Verboten. MSXML4 originally shipped? Currently in "maintenance mode". Microsoft is encouraging people to move off MSXML4 to MSXML6. Currently supported if you are on MSXML4SP2 or later, which shipped in 2003. download MSXML4SP2 here. Can be redisributed. Using the right version of MSXML in Internet Explorer is a good entry on the blog from Microsoft's xmlteam.

• iPhone long plist

  I have some data i want to add in to my app...about 650 categories (includes a name + id number), each with an average of 85 items (each with a name/id number). Will the iPhone support such a large plist? I want to first display the categories in a UITableView, when a category is selected I want to display all of the associated items. Having such a large plist, im not sure if the iPhone will lag when loading the items. At over 51,000 lines it seems like...it might.

• Learn MacRuby or Objective-C?

  - by MaxD

  Well, my fisrt question was a bit too general so i ll try again and hope this one is better. The way i see it is: Ruby-MacRuby or IronRuby or Rails Obj-c-Mac Development So Ruby has clearly more potential in desktop and web platforms and now with MacRuby, OSX native (and commercial) apps are on the way. If i get it wrong please correct me. For me that i will do a fresh start should i go with the modern Ruby or start learning c+obj-c? Will a newcomer benefit much (in learning & coding time, frustration, complexity) by learning/using macruby for osx apps rather objective-c? Or its pretty much the same? I hope some day to hang around here and help others.

• Expose url to webservice

  - by Patrick Peters

  In our project we want to query a document management system for a specific document or movie. The dms returns a URL with the document location (for example: http://mydomain.myserver1.share/mypdf.pdf or http://mydomain.myserver2.share/mymovie.avi). We want to expose the document to internet users and intranet users. The requested file can be large (large video files). Our architecture is like: request goes like: webapp1 - webapp2 - webapp3 - dms response goes like: dms - webapp3 - webapp2 - webapp1 webapp1 could be on the internet. I have have been thinking how we can obfusicate the real url from the dms, due to security issues. I have seen implementations from other webapps where the pdf URL was obfusicated by creating a temp file for the requested document that is specific for the session and user. So other users cannot easily guess the documentname of other users. My question: is there a pattern that deals with exposing company/user vulernable data to the public ? Our development is in C# 3.5.

• An existing connection was forcibly closed by the remote host

  - by George

  I have a fat VB.NET Winform client that is using the an old asmx style web service. Very often, when I perform query that takes a while, I get the subject error. The error happenes The error seems to occur in < 1 min, which is far less that the web service timeout value that I have set or the timeout value on the ADO Command object that is performing the query within the web server. It seems to occur whenever I am performing a large query that expects to return a lot of rows or when I am sending up a large amount of data to the web service. For example, it just occurred when I was passing a large dataset to the web server: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) --- End of inner exception stack trace --- at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Smit.Pipeline.Bo.localhost.WsSR.SaveOptions(String emailId, DataSet dsNeighborhood, DataSet dsOption, DataSet dsTaskApplications, DataSet dsCcUsers, DataSet dsDistinctUsers, DataSet dsReferencedApplications) in C:\My\Code\Pipeline2\Smit.Pipeline.Bo\Web References\localhost\Reference.vb:line 944 at Smit.Pipeline.Bo.Options.Save(TaskApplications updatedTaskApplications) in I've been looking a tons of postings on this error and it is surprising at how varied the circumstances which cause this error are. I've tried messing with Wireshark, but I am clueless how to use it. This application only has about 20 users at any one time and I am able to reproduce this error in the middle of the night when probably no one is using the app, so I don't think that the number of requests to the web server or to the database is high. It's probably one right now when I just got the error now. It seems to have to do everything with the amt of data being passed in either direction. This error is really chronic and killing me. Please help.

• Nginx A/B testing

  - by Alex

  Hey, I'm trying to do A/B testing and I'm using Nginx fo this purpose. My Nginx config file looks like this: events { worker_connections 1024; } error_log /usr/local/experiments/apps/reddit_test/error.log notice; http { rewrite_log on; server { listen 8081; access_log /usr/local/experiments/apps/reddit_test/access.log combined; location / { if ($remote_addr ~ "[02468]$") { rewrite ^(.+)$ /experiment$1 last; } rewrite ^(.+)$ /main$1 last; } location /main { internal; proxy_pass http://www.reddit.com/r/lisp; } location /experiment { internal; proxy_pass http://www.reddit.com/r/haskell; } } } This is kind of working, but css and js files woon't load. Can anyone tell me what's wrong with this config file or what would be the right way to do it? Thanks, Alex

• ASP.NET Membership Provider - Single Login

  - by RSolberg

  I'm considering utilizing the ASP.NET Membership Provider for a few different web apps/tools with a single login approach. REQUIREMENTS User logs in to my.domain.com and sees a list of apps/tools that they have permission to use. The user selects the tool they'd like to use and clicks the link. When the tool opens, it is able to identify that they are currently logged in and who they are to identify any unique permissions to the application. I know that each app could simply point to the same back end Membership Provider DB, however will each app require a login or will it be able to identify if the user is already logged in?

• Are there any working implementations of the rolling hash function used in the Rabin-Karp string sea

  - by c14ppy

  I'm looking to use a rolling hash function so I can take hashes of n-grams of a very large string. For example: "stackoverflow", broken up into 5 grams would be: "stack", "tacko", "ackov", "ckove", "kover", "overf", "verfl", "erflo", "rflow" This is ideal for a rolling hash function because after I calculate the first n-gram hash, the following ones are relatively cheap to calculate because I simply have to drop the first letter of the first hash and add the new last letter of the second hash. I know that in general this hash function is generated as: H = c1ak - 1 + c2ak - 2 + c3ak - 3 + ... + cka0 where a is a constant and c1,...,ck are the input characters. If you follow this link on the Rabin-Karp string search algorithm , it states that "a" is usually some large prime. I want my hashes to be stored in 32 bit integers, so how large of a prime should "a" be, such that I don't overflow my integer? Does there exist an existing implementation of this hash function somewhere that I could already use? Here is an implementation I created: public class hash2 { public int prime = 101; public int hash(String text) { int hash = 0; for(int i = 0; i < text.length(); i++) { char c = text.charAt(i); hash += c * (int) (Math.pow(prime, text.length() - 1 - i)); } return hash; } public int rollHash(int previousHash, String previousText, String currentText) { char firstChar = previousText.charAt(0); char lastChar = currentText.charAt(currentText.length() - 1); int firstCharHash = firstChar * (int) (Math.pow(prime, previousText.length() - 1)); int hash = (previousHash - firstCharHash) * prime + lastChar; return hash; } public static void main(String[] args) { hash2 hashify = new hash2(); int firstHash = hashify.hash("mydog"); System.out.println(firstHash); System.out.println(hashify.hash("ydogr")); System.out.println(hashify.rollHash(firstHash, "mydog", "ydogr")); } } I'm using 101 as my prime. Does it matter if my hashes will overflow? I think this is desirable but I'm not sure. Does this seem like the right way to go about this?

• iPhone - Native App GeoLocation VS Web App GeoLocation

  - by Sam

  Here's my situation; I've built a very simple web app that looks up a users location and plots it on a Google map. Here's my code: http://pastebin.com/d3a185efd When I test it, my location is detected as being = 500 meters from where I actually stand. BUT When I open up Google Maps or Gowalla my location is correct to within <20 meters? So my question is: Do native iPhone apps benefit from a higher accuracy rate than web apps? If so, why?
