Java SE 6 vs. JRE 1.6 vs. JDK 1.6 - What do these mean?
... 1.6.0_07-b06"), and the HotSpot version (on mine, that's "build 10.0-b23, mixed mode"). I suspect the "11.0" you are seeing is the HotSpot version.
Update: HotSpot is (or used to be, now they seem to use it to mean the whole VM) the just-in-time compiler that is built in to the Java Virtual Machi...
How to call asynchronous method from synchronous method in C#?
...rom my AsyncEx library. The official .NET libs don't provide much help for mixing sync and async code (and in general, you shouldn't do it!). I'm waiting for .NET 4.5 RTW and a new non-XP laptop before updating AsyncEx to run on 4.5 (I cannot currently develop for 4.5 because I'm stuck on XP for a f...

The same string of 120 characters (mixed lowercase and non-lowercase ASCII), converted in a loop 40M times (with no cross-file inlining, so the compiler can't optimize away or hoist any of it out of the loop). Same source and dest buffers, so no malloc overhe...

how to check the dtype of a column in python pandas
...('<M8[ns]'), 'is_int64 = False')
It will be misleading in the case of mixed type of data in single column:
df2 = pd.DataFrame({'data': [12, pd.Timestamp('2013-01-02')]},
index = ['A', 'B'])
for col in df2.columns:
df2[col].dtype, 'is_int64 = %s' % isinstance(df2.loc['A', ...
What is the python “with” statement designed for?
...y add it for the sake of completeness: the with statement simplifies exception handling by encapsulating common preparation and cleanup tasks in so-called context managers. More details can be found in PEP 343. For instance, the open statement is a context manager in itself, which lets you open a fi...
