• Best Practices for High Volume CPA Import Operations with ebXML in B2B 11g

  - by Shub Lahiri, A-Team

  Background B2B 11g supports ebXML messaging protocol, where multiple CPAs can be imported via command-line utilities.  This note highlights one aspect of the best practices for import of CPA, when large numbers of CPAs in the excess of several hundreds are required to be maintained within the B2B repository. Symptoms The import of CPA usually is a 2-step process, namely creating a soa.zip file using b2bcpaimport utility based on a CPA properties file and then using b2bimport to import the b2b repository.  The commands are provided below: ant -f ant-b2b-util.xml b2bcpaimport -Dpropfile="<Path to cpp_cpa.properties>" -Dstandard=true ant -f ant-b2b-util.xml b2bimport -Dlocalfile=true -Dexportfile="<Path to soa.zip>" -Doverwrite=true Usually the first command completes fairly quickly regardless of the number of CPAs in the repository. However, as the number of trading partners within the repository goes up, the time to complete the second command could go up to ~30 secs per operation. So, this could add up to a significant amount, if there is a need to import hundreds of CPA in a production system within a limited downtime, maintenance window.  Remedy In situations, where there is a large number of entries to be imported, it is best to setup a staging environment and go through the import operation of each individual CPA in an empty repository. Since, this will be done in an empty repository, the time taken for completion should be reasonable.  After all the partner profiles have been imported, a full repository export can be taken to capture the metadata for all the entries in one file.  If this single file with all the partner entries is imported in a loaded repository, the total time taken for import of all the CPAs should see a dramatic reduction. Results Let us take a look at the numbers to see the benefit of this approach. With a pre-loaded repository of ~400 partners, the individual import time for each entry takes ~30 secs. So, if we had to import another 100 partners, the individual entries will take ~50 minutes (100 times ~30 secs). On the other hand, if we prepare the repository export file of the same 100 partners from a staging environment earlier, the import takes about ~5 mins. The total processing time for the loading of metadata, specially in a production environment, can thus be shortened by almost a factor of 10. Summary The following diagram summarizes the entire approach and process. Acknowledgements The material posted here has been compiled with the help from B2B Engineering and Product Management teams.

• Active Directory Snapshots with Windows Server 2008

  Snapshots are a useful feature of Windows Server 2008. Taking a snapshot of Active Directory as a scheduled task can prove to be a wise precaution in case disaster strikes. Once they are mounted, they can be accessed by any LDAP tool which allows the user to specify a host name and port number. Ben Lye shows how you can restore attributes to a large numbers of broken distribution groups from a snapshot.

• Hashing 3D position into 2D position

  - by notabene

  I am doing volumetric raycasting and curently working on depth jitter. I have 3D position on ray and want to sample 2D noise texture to jitter the depth. Function for converting (or hashing) 3D position to 2D have to produce absolutely different numbers for a little changes (especialy because i am sampling in texture space so sample values differs very very little) and have to be "shader-wise" - so forget about branches, cycles etc. I'm looking forward for yours nice and fast solutions.

• What does 'Nightly Builds' mean?

  - by dbramhall

  I have been using open source projects for a while and been developing upon the open source applications and every so often I come across the words 'Nightly Build' and I have always been curious as to what it actually means. Does it literally mean the projects are done purely as side projects (usually at night after everyone has finished their day jobs) and there's no true contributor/dedicated development team or is it more complex than that?

• Improve Microsoft Visual C++ Application Security and Robustness with SafeInt

  In this age of cloud computing, massive parallel systems and complex security threats like identity theft and decentralized botnets, devoting resources to combat the seemingly age-old issue of integer overflow appears distinctly passC). Despite the fact that integer overflow is such a well know problem, particularly within C and C++ programming, the problem remains a real issue from both a defect and security standpoint, that's why the introduction of the SafeInt template class in Visual C++ 2010 to address overflows is a great addition.

• PowerPivot: Putting two stocks on the same PivotChart

  - by AlbertoFerrari

  In a previous post , I have used a stock exchange scenario to speak about how to compute moving averages in a complex scenario. Playing with the same scenario, I felt the need to compare two stocks on the same chart, choosing the stock names with a slicer. As always, a picture is worth a thousand words, the final result I want to achieve is something like this, where I am comparing Microsoft over Apple during the last 10 years. It is clear that I am not going to comment in any way why traders seem...(read more)

• Our own Daily WTF

  - by Dennis Vroegop

  Originally posted on: http://geekswithblogs.net/dvroegop/archive/2014/08/20/our-own-daily-wtf.aspxIf you're a developer, you've probably heard of the website the DailyWTF. If you haven't, head on over to http://www.thedailywtf.com and read. And laugh. I'll wait. Read it? Good. If you're a bit like me probably you've been wondering how on earth some people ever get hired as a software engineer. Most of the stories there seem to weird to be true: no developer would write software like that right? And then you run into a little nugget of code one of your co-workers wrote. And then you realize: "Hey, it happens everywhere!" Look at this piece of art I found in our codebase recently: public static decimal ToDecimal(this string input) {     System.Globalization.CultureInfo cultureInfo = System.Globalization.CultureInfo.InstalledUICulture;     var numberFormatInfo = (System.Globalization.NumberFormatInfo)cultureInfo.NumberFormat.Clone();     int dotIndex = input.IndexOf(".");     int commaIndex = input.IndexOf(",");     if (dotIndex > commaIndex)         numberFormatInfo.NumberDecimalSeparator = ".";     else if (commaIndex > dotIndex)         numberFormatInfo.NumberDecimalSeparator = ",";     decimal result;     if (decimal.TryParse(input, System.Globalization.NumberStyles.Float, numberFormatInfo, out result))         return result;     else         throw new Exception(string.Format("Invalid input for decimal parsing: {0}. Decimal separator: {1}.", input, numberFormatInfo.NumberDecimalSeparator)); }  Me and a collegue have been looking long and hard at this and what we concluded was the following: Apparently, we don't trust our users to be able to correctly set the culture in Windows. Users aren't able to determine if they should tell Windows to use a decimal point or a comma to display numbers. So what we've done here is make sure that whatever the user enters, we'll translate that into whatever the user WANTS to enter instead of what he actually did. So if you set your locale to US, since you're a US citizen, but you want to enter the number 12.34 in the Dutch style (because, you know, the Dutch are way cooler with numbers) so you enter 12,34 we will understand this and respect your wishes! Of course, if you change your mind and in the next input field you decide to use the decimal dot again, that's fine with us as well. We will do the hard work. Now, I am all for smart software. Software that can handle all sorts of input the user can think of. But this feels a little uhm, I don't know.. wrong.. Or am I too old fashioned?

• How do I replicate the Super Key?

  - by joemangrove

  If you use xmonad, xbindkeys, and xdotool to try and remap the 'Menu' key, it does not work perfectly. The 'Menu' key will only emulate the Super key's quick press action, bringing up the application search. If you hold in the 'Menu' key it will not emulate the Super key's hold down action. That is, bring up the launcer with numbers over the applications. How do you make another key on the keyboard act exactly like the Super key?

• What is a typical profit margin for a small, custom software development shop?

  - by jamieb

  I help manage a small (5-15 employees), custom software development shop. We're hired by various clients to produce web or mobile-based applications. We make everything from pretty simple $10k e-commerce websites to very complex applications that might cost $100k over the course of several months. Our clients are generally start-ups, but we also occasionally work with more established companies (including the federal government). I'm just curious what kind of profit margin would be typical for a business fitting this profile?

• How to write comments to explain the "why" behind the callback function when the function and parameter names are insufficient for that?

  - by snowmantw

  How should I approach writing comments for callback functions? I want to explain the "why" behind the function when the function and parameter names are insufficient to explain what's going on. I have always wonder why comments like this can be so ordinary in documents of libraries in dynamic languages: /** * cb: callback // where's the arguments & effects? */ func foo( cb ) Maybe the common attitude is "you can look into source code on your own after all" which pushes people into leaving minimalist comments like this. But it seems like there should be a better way to comment callback functions. I've tried to comment callbacks in Haskell way: /** * cb: Int -> Char */ func foo(cb) And to be fair, it's usually neat enough. But it gets into trouble when I need to pass some complex structure. The problem being partly due to the lack of type system: /** * cb: Int -> { err: String -> (), success: () -> Char } // too long... */ func foo(cb) Or I have tried this too: /** * cb: Int -> { err: String -> (), * success: () -> Char } // better ? */ func bar(cb) The problem is that you may put the structure in somewhere else, but you must give it a name to reference it. But then when you name a structure you're about to use immediately looks so redundant: // Somewhere else... // ResultCallback: { err: String -> (), success: () -> Char } /** * cb: Int -> ResultCallback // better ?? */ func foo(cb) And it bothers me if I follow the Java-doc like commenting style since it still seems incomplete. The comments don't tell you anything that you couldn't immediately see from looking at the function. /** * @param cb {Function} yeah, it's a function, but you told me nothing about it... * @param err {Function} where should I put this callback's argument ?? * Not to mention the err's own arguments... */ func foo(cb) These examples are JavaScript like with generic functions and parameter names, but I've encountered similar problems in other dynamic languages which allow complex callbacks.

• Google Analytics content experiment vs. funnel visualization

  I am running an experiment on one of the pages in my funnel (the "Choose shipping options" page). But the numbers on the different reports do not correspond. First, I am expecting the 70 entrances in the funnel to equal the 131 experiment visits. Also, I expect the 23 conversions in the funnel to match the 21 transactions below. But they do not. How should I read this information to make good decisions?
