rajeevk··on Ask HN: CTO wants me to leave
IMO, there is no point you try to improve your coding skill at this point of time. As a co-founder, you should try to improve on management skills, try to find replacement of your CTO and then fire him
rajeevk··on Announcing .NET Native Preview
@apardoe, one question: where will the compilation to machine instruction happen? From some comments in this thread, it seems that it will happen at app store server and not at developer's box. If that is the case then why will I need anything to do any settings in VS for building projects?

Also, I would like the title of the article to be changed. IMO, whatever achieved, according to the article, is not an invention. It is just another usage of a dynamo.

rajeevk··on My Tech Cofounder Quit
You have .in domain. Are you targeting only Indian market? IMO, you should try to get .com if you want to go global.
rajeevk··on My Tech Cofounder Quit
Exactly!

Starting up with freelancer is not good idea. The freelancer model will work only if you have a fixed spec which is not the case with most of the tech startup. You always have to take market feedback and quickly incorporate into your product.

rajeevk··on Developing a mobile cross-platform library in C++
I have written a good chuck of common code in C++ for my diagramming app "Lekh Diagram"(http://www.avabodh.com/lekh). The shape recognition, shape management etc all done in C++ code. The app is available for Android and iOS.

Integrating the C++ code with Objective C is much smoother experience than the Java in android.

As the Objective C (more precisely objective C++) is superset of C++, I can directly call C++ code from objective C and for other way communication (calling objective C code from C++), I had defined an C++ interface. The C++ code calls on interface only and the interface is implemented in objective C.

For Android, little more work was required. I had write wrappers code. I also had to hit many stupid issues like local reference table overflow etc.

How is this different from Octopress? In Octopress you can simply edit markdown files and then generate html.
rajeevk··on Your best passive income? (2014)
My first Android app: Scratchpad https://play.google.com/store/apps/details?id=com.avabodh.sc...

I made it to learn Android development. It took me total of 5 days: 2 days to learn basic android stuff then next two days to develop this app and on last day creating dev account and publishing on Android store.

After publishing I forgot the password of signing key I used, so I never updated this app except for a description change. Initially there was almost no revenue but it increased over the time as the download count increased. After two year(of publishing), it is giving me around $70/per month through ads (admob).

rajeevk··on Ask HN: What did you make this year?
I made (ported) Android version of my iOS app Lekh Diagram.

This is (free on Android and paid on iOS) sketch recognition diagramming app.

rajeevk··on Google sues to protect Android device makers from Apple-backed patent hell
I did not say the copying is wrong. I said copying is not innovation
rajeevk··on Google sues to protect Android device makers from Apple-backed patent hell
What kind of innovation do you see in Android? It has been almost being copy-pasted. Google copied everything, from kernel (Linux) to UI design and trying to make lot of money from it and expecting others not to sue.

EDIT: The replies of this comment say that the others (Apple etc) are too copying and copying kernel in not wrong. Well, I did not say that copying is wrong. What I mean is that copying is NOT innovation.

rajeevk··on Starting Feb 1, new apps and app updates must be optimized for iOS 7
You can do it in iOS world too. But the iOS7 is little different. I recently updated my app with iOS7 support. Many places in the code I had to write something like

if(version >= 7) {

  // some code which only works on iOS7
  // or some workaround for iOS7
} else {

  // code which works in older version
}

Previously I never had to write such code to support iOS6 and iOS5 together.

But the situation is much better than Android world. I also have the Android version of the same app (http://www.avabodh.com/lekh)and I have to write lot of version specific if-else in the code.

rajeevk··on A Low Level Curriculum for C and C++
I have written on some low level stuff on C and C++

C++ object model described with c code: http://www.avabodh.com/cxxin/cxx.html

How c code is translated to assembly: http://www.avabodh.com/cin/cin.html

Here is an article (by me) to understand how various c-constructs are translated into assembly

rajeevk··on We're auctioning off a chance for your kid to come to a YC dinner
I agree with michaelochurch. I think this is less important that where the money will be spent than what kind of culture your are creating.

In my observation, here in India (I am from India) that a child born in a poor family remains poor for whole of his life . There are exceptions, but this is true for most of the cases. In my opinion, the reason behind is that the society and culture makes feel a child of poor family that he/she is poor in all aspect of life. This goes to un-conscious mind of children that they are poor and they never come out this thought when they grow up and even if they are very very talented.

Please do make such kind of culture where kids feel bad simply because their parent can't afford something for them. Please do not make kids feel that they belong to a poor family. I can see the current bid is $20K which is a big amount even for a middle class family.

I know that world is not perfect, but we can try making it better at least by not playing the money games in kids matter. If you think further, this kind of culture is a way to society where only children of rich people will get proper healthcare, education etc.

rajeevk··on AppSeed – Turn sketches into functioning prototypes fast
I was also thinking to add similar feature in my app Lekh Diagram (http://www.avabodh.com/lekh). I have not spent much time on this yet but, IMO the biggest challenge in doing sketch recognition is to resolve ambiguity on interpreting recognized shape/strokes . A hand drawn shape can be interpreted differently by different people and can be interpreted differently in different context. A computer program interpreting exactly what user has intention, is a challenging task. But I believe that a system can be build which will probably work 90% of time correctly.

Wishing good luck to these guys!!

agree.. the video recording is very naive. This was recorded with galaxy S4. I am inexperienced in video recording. I still figuring out either this is camera issue or lighting issue.

And there also a orientation (of tablet) issue that you have pointed out.

There is delete icon(image of trash bin) on toolbar. Tap that to delete selected shape. The icon will be visible only after you select the shape.

HN is non predictable. You never know if your are going to make your post to main page or not.

BTW, there were good number of comments in my show HN post for iPad. Don't know why the HN is not showing comments of older post now.

But for iPhone show HN post did not do well. It got only few points
