Just came back from nice little motorcycle ride. Watching big bang theory now.
OT: There is a really old article[^] of Pete about query performance. Those articles do not really cover how execution plan can be really used to improve queries. Now since you have picked up on SQL and are busy writing, how about an addendum? Or may be a brand new series on, probably, this much ignored area.

I am a AWS newbe. I am mucking about with an AWS playtime account, tied to my personal credit card, my costs last month did not exceed $20. My network topologies though seem to quickly get out of hand and am having a hard time visualizing them. Again this is just so I can become familiar with this stuff, playtime as I have said.
Several tools are available to allow me to do visualization, one that I'm interested in is in beta and is based overseas, well actually most of the free ones are (not in friendly countries either). There is one that costs, it is a release version but their visualizations don't look like the Amazon network diagrams you see in AWS help, in addition I have to contact a sales rep to get pricing (no prices on the menu if you will).
The problem is you have to give the visualization people your AWS account info so the diagrams can be generated/ or toplogy generated from the diagram you draw. I hesitate to do that even with a play time account, lest in an hour my AWS account gets abused by the visualization vendor in ways I'm just beginning to imagine.
I have noticed that AWS has a cloud monitor that sends an email if you exceed <edit> a costing </edit> threshold. Hmmm... that's next to worthless.
Anyone run into this and have thoughts on this?

 Simple! Change AWS to WindowAzure. You'll have more control on your servers

I am looking for some help using the Discrete Wavelet Transform (DWT) Library found here: wavelet2d.sourceforge.net/
The trouble is a run time error, which occurs at the DWT function call. It seems to be associated with the length vector in the function call. I want to note that this code was published as is and was reported working by a post doctorate from MIT. Im pretty sure this error is due to something I am doing incorrectly. I created a project file for Microsoft Visual Studio 2013 which I have included here: skydrive.live.com/redir?resid=DF1EA4AE66DE04A3%21128
Note: I placed the two dll files in the system32 folder and the .lib file is included in the MSVC++ Project file which links to the dll’s. I used the release dll's but i get the same result with the debug files. The signal.txt is used by the wavedem1.cpp project file and is operated on.
The error can be easily generated but here is the unhandled exception I am getting: “Unhandled exception at 0x7555D36F in WaveletCode.exe: Microsoft C++ exception: std::length_error at memory location 0x002EF574.”
Here is the call stack: http://img198.imageshack.us/img198/4306/9jdl.jpg It looks like line 65 is causing an issue which is the DWT function call. I tried to look at the "intermediate window" in MSVC++ 2013 but it was empty during execution.
And some more from MSVC++: 'WaveletCode.exe' (Win32): Loaded 'C:\Users\Matt\Desktop\WaveletCode\Debug\WaveletCode.exe'. Symbols loaded.

The end goal is to use this library on a microcontroller for some DSP. Thank you for any help/suggestions you can provide. If you need more information please ask I am relitively new to this.
Thank You.

Welcome to the Lounge, for lazing about and discussing anything in a software developer's life that takes your fancy.
Technical discussions are welcome, but if you need specific help please use the programming forums.
Veni, vidi, vici.

Why didn't you say anything at the time?

Because I have no problem with people helping other people even if they ask in the wrong forum.

Did someone say something? :LooksAroundQuicklySmiley:

OG, my comment was not about your post. It was about other's who abuse the lounge by posting programming questions, not complaints, but then abuse others for doing the same.
Treat others as you'd like to be treated.

I didn't think it was!
It's just my silly sense of humour, I'm afraid...

There is a difference there: CG isn't asking for help, he was just venting his spleen at something that was frustrating him and forgot his trademark "Why Windows 8.1 Sucks Today" title, is all.
Heck, venting is part of what this place is about: why do you think I posted about the stupid mayo this morning? I didn't need CPians to turn up and help clean!

I don't believe you. Confess, you know you wanted help.

Yeah - and where were you when I needed you, huh? Huh?

I followed those posts and it was clear to me that CG did not intend for it to become a technical debate - it ended up being led that way by others and it was not overly long in my opinion.
As for that mayo post... it was outrageous!

No, I agree - it was a rant, nothing more. How these things develop is one of the pleasant unpredictabilities of this place!

by the way how is the cat after being traumatized by the exploding jar?

Fortunately he was outside at the time or it would have added a new set of problems: glass-as-cat-toy and cat-eating-mayo-with-glass-in. As it was I binned his food and water to be on the safe side.

Exactly!

Asking for code to build a robot to clean up after you again eh...if we've told you once we've told you 12.3 times the Codz Plz doesn't work here in the lounge.
