How to use existing Eclipse MAT indexes for interactive analysis

I am attempting to use Eclipse MAT (Memory Analysis Toolkit) to analyze some rather large heap dumps (~2G). My laptop unfortunately has 32bit Windows, and MAT runs out of heap space @ 1.4G allocated heap. I was successful in running the heap indexer from the command line on a large, headless 64bit box. However, I am unable to convince...

I have this MDX query: Exists([Group].[Group Hierarchy].allmembers, {[Group].[Group Full Name].&[121 - Group A], [Group].[Group Full Name].&[700000 - Group C]}) ... which works fine EXCEPT that it returns all of the ancestors of the specified groups as well. What I want is to return JUST the groups from the hierarchy with the spe...

What's the best way to view/analyse/filter huge traces/logfiles?

this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles. since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.w...

Where do you start your design - code, UI, workflow or whatever?

Hi I was discussing this at work, and was wondering where people start their designs? We tend to start with designing code to solve the problem presented to us, but that is probably all of us are (or were) programmers. I was wondering where other people and organisations start their design. Do they start with solving the problem as a ...

How can I load an MP3 or similar music file for display and analysis in wxWidgets?

I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That should be sufficient to get started but later I'd like to add features like identifying beats and...

analysis Big Oh notation psuedocode

I'm having trouble getting my head around algorithm analysis. I seem to be okay identifying linear or squared algorithms but am totally lost with nlogn or logn algorithms, these seem to stem mainly from while loops? Heres an example I was looking at: Algorithm Calculate(A,n) Input: Array A of size n t←0 for i←0 to n-1 do if A[i]...

I am trying to calculate the necessary sample size for a 2x2 factorial design. I have two questions. 1) I am using the package pwr and the one way anova function to calculate the necessary sample size using the following code pwr.anova.test(k = , n = , f = , sig.level = , power = ) However, I would like to look at two way anova, si...

OQL - Find certain (sub)-members of a given object

I'm analyzing heap dumps in a Portal App. With the help of OQL I found the MemorySessionData Object with its address.

How to obtain dependency metrics from Java source code?

For an assignment we have to extract some software metrics from the Hibernate project. We have to extract the afferent coupling and efferent coupling metrics (dependency fan-in, fan-out) from each revision of each package in Hibernate. Some tools were provided which are able to extract these metrics, such as ckjm and JDepend. Other tools...

Can someone recommend a resource/site/book to improve problem solving skills

I am a reasonably experienced developer (.NET, c#, asp.NET etc) but I'd like to hone my problem solving skills. I find that when I come up against a complex problem I sometimes implement a solution that I feel could have been better had I analyzed the problem in a different way. Ideally what I am looking for is a resource of some type t...
