I am curious what kind of considerations a feature such as this should have to go through. First off, I write a blog about this subject, amongst others. See my old blog: http://blogs.msdn.com/b/ericlippert/ and my new blog: http://ericlippert.com for many articles on various aspects of language design. Second, the C# design process is now open … Read more
Try this reference. New, delete, casting, I think there are some more operators and keywords there.
this shows the different ways: — DB2 select * from table fetch first 10 rows only — Informix select first 10 * from table — Microsoft SQL Server and Access select top 10 * from table — MySQL and PostgreSQL select * from table limit 10 — Oracle select * from (select * from table) … Read more
Author answer: I just emailed Mr Van der Linden, and here is what he said: Yes, I agree with the people who answered on stack overflow. I don’t know for certain, because I never used the language B, but it seems highly plausible to me that “auto” ended up in C because it was in … Read more
The accepted answer doesn’t work for me, probably because nvidia-smi has different formats across different versions/hardware. I’m using a much cleaner command: nvidia-smi | grep ‘python’ | awk ‘{ print $3 }’ | xargs -n1 kill -9 You can replace $3 in the awk expression to fit your nvidia-smi output. It is the n-th column … Read more
The type keyword is there to create a new type. This is called type definition. The new type (in your case, Vertex) will have the same structure as the underlying type (the struct with X and Y). That line is basically saying “create a type called Vertex based on a struct of X int and … Read more

The open keyword means “open for extension“ – i.e. it’s possible to create subclasses of an open class: The open annotation on a class is the opposite of Java’s final: it allows others to inherit from this class. By default, all classes in Kotlin are final, which corresponds to Effective Java, Item 17: Design and … Read more
It allows the differentiation of bitwise const and logical const. Logical const is when an object doesn’t change in a way that is visible through the public interface, like your locking example. Another example would be a class that computes a value the first time it is requested, and caches the result. Since c++11 mutable … Read more
Possibly because Python 2.6 not only allowed True = False but also allowed you to say funny things like: __builtin__.True = False which would reset True to False for the entire process. It can lead to really funny things happening: >>> import __builtin__ >>> __builtin__.True = False >>> True False >>> False False >>> __builtin__.False … Read more
