I have been using R's filehash library to solve the "out of memory" problem, to store the large datasets in hashfiles, and the load/updating the file when use it. Given that most of the systems are now using SSD harddisk, I found this solution is good enough for me to solve my "out of memory" problem and a good balance between running time. I am now writing my codes in Python, but could not find any equivalent package. Could anyone shed some light for me? Thanks.
I have been reading some information about hashlib package in Python, but not quite sure if it is the samilar application as to create a hashfile and load it out.

For the Spacy package, model files for deps, ner, and pos throw an invalid load key or EOF error when I try to load them using pickle.
I have executed the code on windows and linux systems. I don't think it is a binary mode transfer issue. I have checked it in detail. I am not able to figure out the issue. Most likely the file is corrupt but I am not sure. Is there a way it can be fixed using the hex editor?
Any help is highly appreciated. It will be great if someone can explain pickling in a bit detail.
Appreciate your help.
The English() object in Spacy is not pickable. See issue #125
I'm having trouble with the library of DSNUTILB. I dont know what library it belongs to. I've been surfing the net but can't seem to find the answer to this. Can anyone help out? How to find the library? Thanks.
DSNUTILB is delivered by default in the SDSNLOAD dataset by IBM. Look in the appropriate SDSNLOAD dataset that is allocated by your DB2 subsystem.
1)I am new to programming and was wondering how one would go about getting an image from a file location to the screen in python without having to import any modules (if this is possible).
2)Maybe what I am really asking is for a tutorial or an advance tutorial on python, computer programming in general, or maybe some tutorials in computer science. Some direction and guidance on where I can answer all of my question about what is part of the python programming language and what is made for quick and easy coding would be appreciated. (An example question of what I would liked answered is "can I make every built in and downloadable python module using just python code or is lower level coding needed and if no lower level coding is needed what is the python code to make these really cool modules"?)
(I took a beginners class in python and have become extremely fond of computers ever since. Now I have been teaching myself C++ and Java and just want to understand the details behind these languages and want to understand how computer scientist and software engineers create the things they do so sorry if I ask a lot of questions.)
1) Of course it's not possible. You can open the image file, but to render it on the screen you need some sort of graphical toolkit, and you need to import modules to do that.
In fact, only the absolutely most common things are, as it's called, "built in" in Python. You need to import a lot in Python, and there is no reason for you not to do this, so the question in itself doesn't make sense.
2) There are tons of tutorials that do what you want. One of the most popular ones are "Learn Python the Hard Way". I've looked at it briefly and it seems good.
I want to write a small kernel module in which I have to take a static string, hex-encode it and then use arc4 algorithm to encrypt it and then reverse the process. The logic is pretty clear to me. What I am suffering is that of a guideline of using the crypto api. I cannot exactly find the way out. If some one can give me a rough introduction or a useful link, it will be of much help to me. I searched a lot about it, but could not figure it out exactly. Thanks in advance.
I am a normal user and does not have strong background in programming.
I have a 64 bit, dual core machine (Dell Vostro 3400) and I think I can run multithreaded program with this machine (yes?)
The program that I think could be convert into multithreaded program is this:
http://code.google.com/p/malwarecookbook/source/browse/trunk/3/8/pescanner.py
Is possible to do so?
If yes, which part should being edited so that it will work?
Thanks.
Multithreading is not an easy subject.
I suggest you read up on some tutorials, see:
http://www.tutorialspoint.com/python/python_multithreading.htm
http://www.devshed.com/c/a/Python/Basic-Threading-in-Python/
http://www.artfulcode.net/articles/multi-threading-python/
To answer the general part of your question, you can run multithreaded code an any machine newer than say 2000.
Your question is too broad though to answer without going into details on the code.
My suggestion
I suggest you try the tutorials first and write same sample programs, ask a specific question with sourcecode! if you get stuck.
That's a road I'd recommend rather than taking someone else's code and rewriting it without detailed knowledge of threads.
