Memory leak detection tools

"gflags -i foobar.exe +ust" to enable stack tracing.
"set _NT_SYMBOL_PATH= SRV*c:\symbols* http://msdl.microsoft.com/download/symbols" to set the symbol path.
Download umdh tools from Microsoft.
"umdh -p:124 -ffoobar.log" to take multiple snapshots.
""dhcmp foobar1.log foobar2.log" to compare the snapshots ie. leaks.

And, then there is ftp://ftp.microsoft.com/ PSS/Tools/Developer%20Support%20Tools/LeakDiag/leakdiag125.msi - this can also be used to take debug dumps of any process.

Google Appengine

It was good while it lasted, Google AppEngine gave developers an easy way to create web applications without worrying about scaling it or being a sysadmin. There were numerous startups that built their products on Google Appengine. Even after beta, there was a fairly large free quota that made it a reasonable choice. But, the current pricing seems a bit ridiculous for those who are looking for a free or cheap solution or for those enjoyed the initial quotas. Perhaps, we were spoiled and Google’s goal is to get rid of free-riders which is not exactly evil from Google’s perspective. So, it is 2012 and welcome to reality since Google can’t maintain those quotas forever and the current free quotas are intended to only test your application before you go live. If for some strange reason, your application becomes popular and gets more than 1,000 users, you would end up scrambling for an alternate solution since you will find yourself paying through the nose. The quota system is complica...

Did you ever have to analyze large log files before?

Well, I recently had to analyze a large log based dataset and decided to try out the ELK stack . Introduction: Please see this intro if you are not familiar with ELK, the rest of the blog assumes you know what they are. eg. elastic server, logstash & kibana. It is a popular server side tool to index, search & graph a large collection of logs or similar structured/unstructured data. This blog post mainly talks about my experience setting up this well known stack & the unexpected things learnt during the process. Goal : "How do I enable rich filtering & analysis on the large set of product logs beyond some simple scripting?" I thought I just had to upload a few log files to the server & then have some awesome graphs appear almost magically out of the box! Servers : "How do I get a server up and running?" There is a free trial for cloud based elastic stack. I signed up and got a 14 day free trial with 4 instance running on Google Clo...

Mobile tech landscape

Just some personal thoughts from development and business perspectives: Apple - iPhones and iOS; top of the line industrial design and beautiful user interfaces. Combine this with the maturity of the Mac OS platform, excellent native development tools and users willing to buy apps on AppStore this is a top platform to target. The requirement for Macs & to learn Objective-C are initial deterrents, but probably it just helps keep Windows developers away. The simple fact is that develepors will be where the money is and Apple Appstore is one place where open source hasn't yet taken away the revenues for indie developers. iPads have extended the success of iPhones, but has made it challenging for developers to target multiple screen sizes. Android - This is one of the hottest mobile platforms; mainly because people equate this to PC vs Mac from the good old days. (open vs closed). The Android platform is indeed one of the most developer friendly mobile platforms out there, it...
