java - Sorting+merging lines of multiple files according to a timestamp -

-

I have several text files that represent logging entries that I need to parse later. Each file is 1 M is above the size and I have about 10 files. Each row has the following format: 

  timestamp \ t data   
 I merge all the files And the entries must be sorted by the timestamp value. There is no guarantee that entries of 1 file are in the correct chronological order.  
 What will be the smartest approach? My proxy code looks like this:  
  list & lt; FileEntry & gt; EkBeglist = New Arrestist & lt; File Entry & gt; (); For each file {parse each row in an instance of the file extension; Add an example to a buglist; } Collections.sort (According to OneBigList, FileEntry.getTimestamp ());

If you are not sure that your work will fit in the available memory, After parsing the database table, worry about putting your lines and how to order the data in the database (an index will help in the timestamp column: -)

If you are sure that there is a problem with the storage If not, then I

make sure your file entry class goes Second is hash code () , according to your sort order equals () and comparative .

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
