Lots of data over a service

2013-08-06 Thread Greg Keogh
Folks, I have to send several thousand database entities of different types to both a Silverlight 5 and WPF app for display in a grid. I can't page the data because it's all got to be loaded to allow a snappy response to filtering it. I'm fishing for ways of getting the data across with the least

Hi Greg, What I did with my Motion Chart software ( http://www.eshiftlog.com/Silverlight/MotionGraphTestPage.html) to get better download performance was: • Move away from small WCF data transfers to transferring a single large encoded compressed text file • Only transfer raw data (no JSON/XML

Hi Greg, We've used a technique called Chunking to move large quantities of binary data around. We move ~50 Mb files (LAN only) this way and works pretty well. http://msdn.microsoft.com/en-us/library/aa717050.aspx Rob From: ozdotnet-boun...@ozdotnet.com

Howdy Greg #2 (or 3?) Haven't seen you since the Silverlight weekend in Docklands a few years ago. Very interesting! You have implemented your own data compression, and we used to do very similar things back in the late 70s and 80s when mainframe disk space was precious. Compression algorithms

Greg, I saw the TED talk that you note was the inspiration for this. I thought at the time it was a brilliant way to present and understand data. Plus it and the presenter had the audience totally amused but it really made the data talk. Is this something you will use yourself or for a

Hi Greg #N+1, That Silverlight weekend in Docklands was a great event, thank you to the guys that organised it! I would not say that I implemented my own data compression, more I avoided any extra fat in the data. I agree that I would not have been getting much extra mileage out of the

Hi Paul, Is this something you will use yourself or for a client, or propose to make available one way or another? This is work that I did myself as a side project some years ago to cement my Silverlight and C# knowledge. I tried to find some commercial interest in it, but it just was not

Hi Rob, I actually implemented a similar chunking technique from scratch last year between WCF over http and an SL4 app. I simulated a simple torrent idea where numbered chunks are sent to the server who assembles them in a receiving array of the correct size. The only tricky code was on the SL

Server Application Monitoring

Hi, I'm looking for some recommendations for a system that does Server Application Monitoring for our servers. I've tried NewRelic and while it's an impressive product they don't have very good support for custom metrics and instrumentation. I'd like to be able to publish my own metrics that

In this age of 'big data' you'd think there would be a big commercialisation opportunity for visualising both small and large data sets in that way. Standardise the input data formats so people can prepare their own data and interpolate missing points and it would have to be huge for management

PRTG is the go. It was recommended to me by someone on this list (thanks!) and it is boss. We use it to monitor s truck load of stuff and it is very flexible. Some parts of it that are boss: - It is entirely agent based. Even in a single server install it uses a local probe to do the polls.

Options for exposing TFS to customers and/or ticketing system

2013-08-06 Thread Preet Sangha
We are now big enough to require a ticketing system to manage customer requests/tasks. Internally (8 of us) we use cloud TFS (visualstudio.com) and Office 365 so a cloud based solution suits us better then us having to manage it. In fact our whole infrastructure is slowly migrating to azure

David, Thanks for the reference. I'll check 1. I don't have a server to allocate for this. My servers are all in the cloud in various locations. I really want a service not a product :) 2. I don't see anything in their list specific to .Net. NewRelic has very good profiling for .Net On Wed,
