If you’re using a theory testing framework like Junit’s or Robolectric’s, make sure to run the class containing the test you want, instead the test itself. Since these frameworks use the test methods as instance methods instead of static methods, any testing framework looking for a normal public static test won’t find anything.
Are functional languages inherently slow? In some sense, yes. They require infrastructure that inevitably adds overheads over what can theoretically be attained using assembler by hand. In particular, first-class lexical closures only work well with garbage collection because they allow values to be carried out of scope. Why are functional languages always tailing behind C … Read more
Beware!! Using the below command to check compilation errors in your Perl program can be dangerous. $ perl -c yourperlprogram Randal has written a very nice article on this topic which you should check out Sanity-checking your Perl code (Linux Magazine Column 91, Mar 2007) Quoting from his article: Probably the simplest thing we can … Read more
from sklearn.preprocessing import Imputer was deprecated with scikit-learn v0.20.4 and removed as of v0.22.2. See the sklean changelog. from sklearn.impute import SimpleImputer import numpy as np imputer = SimpleImputer(missing_values=np.nan, strategy=’mean’) pip install scikit-learn==0.20.4 or conda install scikit-learn=0.20.4 are not a good options because scikit-learn==0.20.4 is more than 3 years out of date.

You need to set the environmental variables for cl. C:\Python31\python.exe C:\Python31\Scripts\cython.py smalltest1.py –embed cl.exe /nologo /Ox /MD /W3 /GS- /DNDEBUG … Read more
A collection of CPP sources (H files and CPP files) can be compiled together in to a “library,” which can then be used in other programs and libraries. The specifics of how to do this are platform- and toolchain-specific, so I leave it to you to discover the details. However, I’ll provide a couple links … Read more
Reason [1] Faster compile times Not in my projects: source files (CPP) only include the headers (HPP) they need. So when I need to recompile only one CPP because of a tiny change, I have ten times the same number of files that are not recompiled. Perhaps you should break down your project in more … Read more
What does your .h file end with? I’m guessing that the end of your class defnition does not have a “;”. The class is being interpreted as the return type of the first function in your cpp file.
In Linux (you never mentioned which OS you’re on, so this could be relevant) you can create block devices from RAM and mount them like any other block device (that is, a HDD). You can then create scripts that copy to and from that drive on start-up / shutdown, as well as periodically. For example, … Read more
