Brother MFC-490cw unable to print 70

My wife is studying as last year college student and one of her friend knows that I am a software engineer so yesterday she called my wife that the printer was not working.  Its funny I asked her to do a video chat and bring laptop near the printer and show me the issue.

First issue was that she had recently changed the ink so I asked her to take out the cartridge and show me and it seems she hasnt pulled the plastic wrapper in front of ink nozzle.

Now even after removing it the print was not working so I asked her to put something on scanner tray and try to copy it and again it was same issue "Unable to print 70".

It seems real issue was paper stuck issue near the cartridge and I asked her to remove it and volla the problem was solved.


Funnies part of the story was that I was going ROFL when I found unable to print 70 was related  to paper stuck issue, being an engineer I can feel the pain of a non IT user who would not know how the heck to connect unable to print 70 to paper stuck issue. For us its natural that we tweak different things and try again and repeat the cycle until we have found the issue :).

Logging to Graphite monitoring tool from java

We use Graphite as a tool for monitoring some stats and watch trends. A requirement is to monitor impact of new releases as build is deployed to app nodes to see if things like
1) Has the memcache usage increased.
2) Has the no of Java exceptions went up.
3) Is the app using more tomcat threads.
Here is a screenshot

We changed the installer to log a deploy event when a new build is deployed. I wrote a simple spring bean to log graphite events using java. Logging to graphite is easy, all you need to do is open a socket and send lines of events.
import org.slf4j.Logger;import org.slf4j.LoggerFactory; import java.io.OutputStreamWriter; import java.io.Writer; import java.net.Socket; import java.util.HashMap; import java.util.Map; public class GraphiteLogger { private static final Logger logger = LoggerFactory.getLogger(GraphiteLogger.class); private String graphiteHost; private int graphitePort; public String getGraphiteHost() { return graphiteHost; } public void setGraphite…

Jersey posting multipart data

This took me sometime to figure out mostly it was because I was only including jersey-multipart-1.6.jar but I was not including mimepull-1.3.jar.

So the intent is to upload a file using REST api and we need pass meta attributes in addition to uploading the file. Also the intent is to stream the file instead of first storing it on the local disk. Here is some sample code.
@Path("/upload-service") public class UploadService { @Context protected HttpServletResponse response; @Context protected HttpServletRequest request; @POST @Consumes(MediaType.MULTIPART_FORM_DATA) @Produces(MediaType.APPLICATION_JSON) public String uploadFile(@PathParam("fileName") final String fileName, @FormDataParam("workgroupId") String workgroupId, @FormDataParam("userId") final int userId, @FormDataParam("content") final InputStream content) throws JSONException { //.......Upload the file to S3 or netapp or any storage service } }
Now to tes…
