问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: How do I determine if my python shell is executing in 32bit or 64bit mode? I made a question earlier that never got replied to, but I have something more specific now so hopefully you can help. Basically the SendKeys library only appears to install on my 32 bit system of Windows... So I was wondering if there is a way of making it so this function I am going to write will only execute on a 32 bit system? I

问题 I need to know whether I compiled libjpeg for 32 or 64 bits architecture, but don't know how to find out, is there a command that will let me check? 回答1: just type file libjpeg.dylib and you'll get output like the following libpoll.dylib: Mach-O universal binary with 3 architectures libpoll.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64 libpoll.dylib (for architecture i386): Mach-O dynamically linked shared library i386 libpoll.dylib (for architecture

I'm keen to understand what their architecture is like and how they fit the different pieces together; how they store the repositories, how they access those repositories to show file contents, how they handle displaying diffs, etc. Could

问题 I will likely be involved in a project where an important component is a storage for a large number of files (in this case images, but it should just act as a file storage). Number of incoming files is expected to be around 500,000 per week (averaging around 100 Kb each), peaking around 100,000 files per day and 5 per second. Total number of files is expected to reach tens of million before reaching an equilibrium where files are being expired for various reasons at the input rate. So I need

问题 First off, I think this is somewhat ridiculous to do but the other members of my team insist upon it and I can't come up with a good argument against it other than "I think it's dumb"... What we're trying to do is create a completely abstract data layer and then have various implementations of that data layer. Simple enough, right? Enter Entity Framework 4.1... Our end goal here is that the programmers (I do my best to stay only on the data layer) never want to have to be exposed to the

问题 I'm trying to understand what makes Nginx so fast, and I have a few questions. As I understand it, Apache either spawns a new process to serve each request OR spawns a new thread to serve each request. Since each new thread shares virtual address space the memory usage keeps climbs if there are a number of concurrent requests coming in. Nginx solves this by having just one listening process(Master), with a single execution thread AND 2 or 3(number is configurable) worker processes. This

Greetings, I've been toying with an idea for a new project and was wondering if anyone has any idea on how a service like Kayak.com is able to aggregate data from so many sources so quickly and accurately. More specifically, do you think Kayak.com is interacting with APIs or are

问题 I am asking this question regarding Haswell Microarchitetcure(Intel Xeon E5-2640-v3 CPU). From the specifications of the CPU and other resources I found out that there are 10 LFBs and Size of the super queue is 16. I have two questions related to LFBs and SuperQueues: 1) What will be the maximum degree of memory level parallelism the system can provide, 10 or 16(LFBs or SQ)? 2) According to some sources every L1D miss is recorded in SQ and then SQ assigns the Line fill buffer and at some
