#vs2013

After going through some photos from VS fashion shows something caught my eye… Here it is:

Lily Aldrige and Taylor are very good friends, right? I mean, Lily was the reason why Taylor even sang during VS 2013 show, she introduced the idea of it!

So, why she seems to refuse to hold her hand?

It seems that at first she wasn’t expecting that Lily would take her hand… but after the initial surprise shouldn’t she just happily grab her friend’s hand? 

Was she SO nervous…? It seems unlikely to me… She was with her friend and she performed on many different stages before!

I’d like to think that maybe… just maybe she didn’t want to make someone feel jealous, in-needed or insecure…

And year later we have this:

A Simple USB desktop locker

Introduction

USB desktop locker is a common thing in the world of computer. Search it in Google and you will find lots of software either free or paid. In search of this kind of software  I found one very useful. But being a software developer I thought why don’t I  create my own USB locker? As i thought i made one for my personal use and here it is with full source code for all of you.

How it…

Today I got the concatenation and resampling of saddle point stream traces with existing gradient paths working correctly. I realized that I need the saddle point stream traces to be offset from those seeded from neighboring nodes so that the resulting volumes are still triangular, so there's that to do before I can make surfaces.

Also still need to add the detection of whether a volume straddles more than one #IrreducibleBundle.

Improved the mesh optimization. It now uses the max of local triangle variance for convergence testing rather than the total variance. It's a bit slow though. I sped things up with some openmp inside the variance function, but it's still slow since the majority of the work is inherently serial. Makes me appreciate the benefit of having all your own functions for stream traces and stuff; don't need to worry about one thread making a stream trace and then another thread stealing it by calling getnumzones at the wrong time.

Might be able to speed up the mesh optimization by doing a few iterations of jiggle mesh before I start the actual optimizer. That'll let things move around to fit the constraints in a way cheaper way, then the optimizer just needs to do the fine adjustments.

Also made GBA play nice with Tecplot, announcing data loads and even mesh memory requirements.

That's one thing I need to do for the data loaders is announce the memory required to Tecplot.

Take another whack at some basic openmp parallelism in #Bondalyzer. It might work better in #VS2013.

Personal

Otherwise today was good. #Kaori got another paycheck, I finished digitizing the rest of my file cabinet—it's now useless, I did everything but the essays for the #DOE #CSGF application, we had pineapple fried rice for lunch and yasai itame for dinner.

Remind me to check that the transcripts I ordered from #Mines included undergrad and grad.

The files that finally worked, and that I assume will help with future versions of GSL and VS were taken from the following URL.

http://brgladman.org/oldsite/computing/gnu_scientific_library.php

And the blog that finally let me see the light (told me about the readme) was http://qubitcal.blogspot.com/2013/08/gsl-on-windows.html

Now I can finally get #Meshgen running in windows so that #GradientBundleAnalysis can get underway!

Software #Programming

I’m having a bitch of a time getting #GSL to build in #VS2013. I found several remade VS solutions to get the job done, but for all of them I’m able to build the static (.lib) library, but I can’t get the dynamic (.dll) to build. I get errors like X:\TimAddOnsWin\BondalyzerSuite\gsl-1.16-vc11\gsl/gsl_sys.h(36) : see declaration of 'gsl_expm1' 1>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include\math.h(503): error C2375: 'gsl_log1p' : redefinition; different linkage and have no idea (right now anyways) how to fix them!

Software #Programming

1. Download and install the .NET Framework 4.6

Building the psycopg2.6 in Python 2.7 has to use the VS2008 environment. Otherwise you will get an error message “Unable to find vcvarsall.bat”. But, now days, it’s hard to get VS2008 VC 9.0. If you have VS2013 already been installed, you can have a OS environment variable set as a simple workaround. For example, i have installed VS2013 in C:\app\VS12:

SET VS90COMNTOOLS=C:\app\VS12\Commons7\Tools\

The Python 2.7 psycopg2 setup script will look forward this environment variable and locate the vcvarsall.bat.

And then, the VC 12.0 has different headers and libraries from VC9.0. That will cause the error message showing below:

psycopgmodule.c .\psycopg/config.h(134) : warning C4005: 'isnan' : macro redefinition        C:\app\VS12\VC\INCLUDE\math.h(289) : see previous definition of 'isnan' .\psycopg/config.h(138) : warning C4005: 'isinf' : macro redefinition        C:\app\VS12\VC\INCLUDE\math.h(288) : see previous definition of 'isinf' .\psycopg/config.h(150) : error C2491: 'round' : definition of dllimport function not allowed error: Setup script exited with error: command 'C:\\app\\VS12\\VC\\BIN\\amd64\\cl.exe' failed with exit status 2

To fix this one, you could apply this patch lines below to psycopg2.6\psycopg\config.h:

Then, you could run the "easy_install .", you should be OK to build now.

However, this is not the whole story either a happy ending. When you start up the Python and import psycopg2 module, it will fail to load DLLs which psycopg2 depends on. These DLLs can be found in PostgreSQL Windows installation \bin folder. Copy the bin\lib*.dll, ssleay32.dll and zlib1.dll to your Python 2.7\\Lib\site-packages\psycopg2-2.6-py2.7-win-amd64.egg\psycopg2 folder. Now, you should be all set.
