How does the JVM work considering computer organization?

问题 I thought I've always understood why Java was portable, until I took Computer Organization. This is my interpretation of a C program from start to finish: C program --> compiler --> assembly --> machine code --> ISA --> micro architecture (how the computer interprets ISA) --> logic gate --> circuit --> device Where the compiler must have knowledge of the ISA. Also, the assembly and machine code will vary based on ISA. Java is as such: (inside JVM): Java program --> compiler --> bytecode

Why can't sub-packages see package private classes?

问题 Okay so, I have this project structure: package A.B class SuperClass (this class is marked package private) package A.B.C class SubClass (inherits from super class) I'd rather not make SuperClass publicly visible... It is really just a utility class for this specific project (A.B). It seems to me that SubClass should be able to see SuperClass , because package A.B.C is a subpackage of A.B... but this is not the case. What would be the best way to resolve this issue? I don't think it makes

How To Reduce Python Script Memory Usage

戏子无情 提交于 2020-06-09 07:31:09
问题 I have a very large python script, 200K, that I would like to use as little memory as possible. It looks something like: # a lot of data structures r = [34, 78, 43, 12, 99] # a lot of functions that I use all the time def func1(word): return len(word) + 2 # a lot of functions that I rarely use def func1(word): return len(word) + 2 # my main loop while 1: # lots of code # calls functions If I put the functions that I rarely use in a module, and import them dynamically only if necessary, I can

How to share code between multiple GWT eclipse projects?

陌路散爱 提交于 2020-01-22 15:25:49
问题 I would like to have multiple GWT projects that share common code. Is this possible? AFAICT my GWT projects need to each have their own directory, with source directly underneath, which seems to preclude code-sharing. I tried using linked folders, but GWT didn't seem to like that (described here). If I want to do this, is my only choice to turn the code I want to share into a .jar file, and then inherit that in each of my projects' XML files? Is there a way to make eclipse automatically do

How can I organise this Go code that redefines methods from an embedded type to be less redundant and more maintainable?

久未见 提交于 2020-01-15 10:14:47
问题 I have some example code in which I declare a type foo with some methods which call each other (say: foo.get , which is called by foo.double and foo.toString ). I have another type, bar , which embeds foo and redefines get . I am forced to redefine double and toString on bar , so they can see bar.get (rather than only foo.get ), but the body of these functions is basically identical to the original. Is there a better way to organise this code, to avoid the redundancy while still having bar

What do you use the svn tags directory for anyways?

拟墨画扇 提交于 2020-01-10 02:34:06
问题 Ok so we all know the standard SVN set-up of trunk\ branches\ tags\ And I realize that the recommendation is that tags should have "special" commits in it. I've never really used the tags directory however and I don't see why I ever would. My understanding is that tags\ would contain things like "Version1Release\, Version2Release\, ThatTimeWeUpgradedEverthing\" etc. But here's the thing, if you are going in and need to make a change to the Version1Release then it should be a branch, and if

How should I organize my c# solution?

主宰稳场 提交于 2020-01-04 05:21:15
问题 I have three projects in my C# 4 solution. MooDB: Has my domain objects in, NHibernate mappings, presentation classes. Data: Has my data access layer classes (using NHibernate) Test: Has my test classes Here's a screenshot: I've noticed that I've got app.config and hibernate.cfg.xml in my Test project. This does seem right. I don't have an app.config in my Data project which is a problem because I want to use log4net in my Data project but I can't configure it if there's no app.config there.
