• Replacing deprecated <:< Manifest type witness in Scala 2.10

  - by Josh

  Can someone point me at what I should be doing under scala 2.10 in place of this deprecated type witness on Manifest? reflect.ClassManifest.singleType(foo) <:< barManifest Honestly, my goal here is just to replace it with something that doesn't raise a deprecation warning. I'm happy to use the new reflection API. Here's the code in question in context, if that's important: https://github.com/azavea/geotrellis/blob/master/src/main/scala/geotrellis/feature/op/geometry/geometry.scala#L45

• Using CreateOrthographicOffCenter in XNA

  - by Jeffrey Kern

  I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up space from 0,0 to 1,1?

• What is the total amount of public IPv4 addresses?

  - by Earlz

  Yes, I am needing to know what the total number possible IPs in the public IPv4 space. I'm not sure where to even get a neat list of all the IP address ranges, so could someone point me to a resource to calculate this myself or calculate the total number of IPs for me? Also, by Public IPs I mean not counting reserved or private-range IP addresses.. Only the ones that can be access through the internet.

• Distributing iPhone App to developers in your team through iTunes

  - by Rudiger

  Hi everyone, Was wondering if you can distribute your App to other developers in your team through iTunes. I guess you would upload the App as a beta version through iTunes Connect and anyone with a provisioned iPhone would receive the update. I didn't think it was possible but someone told me they were sure you could. If this is not possible are there any other benefits of a company standard enrolment besides being able to add other people so they can get the same resources? Thanks

• Java serialization testing

  - by Jeff Storey

  Does anyone know if there is a library that exists to help test if an object graph is fully serializable? It would probably be as simple as writing it out and reading it back in, but I figured someone must have abstracted this already - I just can't find it.

• How to convert a video via ffmpeg to an mp4 format that will stream and/or download to iPhone and Bl

  - by Yegor

  I have a site where people upload videos, which are converted to .flv format. Simple. I wanted to also convert to an mp4 format that will "stream" to an iphone and blackberry, or allowed to be downloaded to either, for later viewing. Can someone post a working ffmpeg line to accomplish this task? Closest I got was this (which doesn't work) ffmpeg -i in.avi -f mp4 -vcodec libx264 -maxrate 1000 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec libfaac -s 480x320 -ab 128k -qscale 7 out.mp4

• How to program simple chat bot AI?

  - by Larsenal

  I want to build a bot that asks someone a few simple questions and branches based on the answer. I realize parsing meaning from the human responses will be challenging, but how do you setup the program to deal with the "state" of the conversation? EDIT: It will be a one-to-one conversation between a human and the bot.

• MongoDB query against geospatial index with maxDistance fails from node.js client

  - by user1735497

  I want to query against a geospatial index in mongo-db (designed after this tutorial http://www.mongodb.org/display/DOCS/Geospatial+Indexing). So when I execute this from the shell everything works fine: db.sellingpoints.find(( { location : { $near: [48.190120, 16.270895], $maxDistance: 7 / 111.2 } } ); but the same query from my nodejs application (using mongoskin or mongoose), won't return any results until i set the distance-value to a very high number (5690) db.collection('sellingpoints') .find({ location: { $near: [lat,lng], $maxDistance: distance / 111.2} }) .limit(limit) .toArray(callback); Has someone any idea how to fix that?

• HTML 5 Canvas performance

  - by Vilius

  Hello there! I'm just started on playing around with the canvas HTML5-object. For the sake of performance tests, I have made a little ping pong game (http://bit.ly/arTPut). Apart from my quick'n'dirty programming skills, I believe, that there are also some performance boosts, I haven't used. Especially, the ball seams to be blue with a little red-touch, but by my decleration it should be yellow. Would be very nice, if someone could help me! Greetings, Vilius
