   • Which is the best way to make a MATLAB ga function that calls the simulation software and has access to the result?

     Top Answer

     Answered Nov 09, 2016 · 1 votes

     You can do so by using an external function that uses system calls to run your simulation software and manipulate it's output.

     for example:

     ga(@(x1)my_external_obj_fn(x1,param1,param2,...),nelements, nvars,A,b,[],[],LB,UB,@my_nonlcon_fn,@my_IntCon_fn,options)...-

     and in your output = my_external_obj_fn

     ...sim_fx = sprintf('your_sim_exec param1 param2... %s > outputfile');system(sim_fx);getoutput = sprintf('grep outputfile | sed > out_fitness')system(getoutput)fID = fopen(getoutput)if fID ~= -1output = textscan(fopen(fx2), '%s');output = str2double(output)...

     Hope this helps

   • Which is the best OS for web application development?

     Answered Jun 28, 2011 · 2 votes

     Linux is great option because of the following:

     • Software/Tools availability
     • Relatively easy troubleshooting
     • Easy to find answers on any question/error code you get
     • Great package management (Debian/Ubuntu and derivatives)
     • Friendly community
     • and many more

     About the machine configuration more RAM, more HDD space, better CPU, ... :). In the company I work, every in-house developed piece of software is developed and hosted on Linux. I really can not remember of any issues we've had, except minor hardware related ones.

   • Which is the best way to read the last line of a text file in Java?

     Top Answer

     Answered Sep 14, 2011 · 8 votes

     The simplest way to do it is simply to iterate over the lines in the file and stop when you reach the end. For example:

     // I assume this is disposed properly etcprivate static String getLastLine(BufferedReader reader) throws IOException { String line = null; String nextLine; while ((nextLine = reader.readLine()) != null) { line = nextLine; } return line;}

     This will return null for an empty reader.

     Unless I knew I was going to have to read a really big file, that's what I'd do. Trying to do this by skipping straight to the last line is hard. Really hard, especially if you need a variable-width encoding such as UTF-8.

   • Which is the best way to check for the existence of an attribute?

     Top Answer

     Answered Mar 17, 2012 · 177 votes

     There is no "best" way, because you are never just checking to see if an attribute exists; it is always a part of some larger program. There are several correct ways and one notable incorrect way.

     The wrong way

     if 'property' in a.__dict__: a.property

     Here is a demonstration which shows this technique failing:

     class A(object): @property def prop(self): return 3a = A()print "'prop' in a.__dict__ =", 'prop' in a.__dict__print "hasattr(a, 'prop') =", hasattr(a, 'prop')print "a.prop =", a.prop

     Output:

     Most of the time, you don't want to mess with __dict__. It's a special attribute for doing special things, and checking to see if an attribute exists is fairly mundane.

     The EAFP way

     A common idiom in Python is "easier to ask for forgiveness than permission", or EAFP for short. You will see lots of Python code that uses this idiom, and not just for checking attribute existence.

     # Cached attributetry: big_object = self.big_object # or getattr(self, 'big_object')except AttributeError: # Creating the Big Object takes five days # and three hundred pounds of over-ripe melons. big_object = CreateBigObject() self.big_object = big_objectbig_object.do_something()

     Note that this is exactly the same idiom for opening a file that may not exist.

     try: f = open('some_file', 'r')except IOError as ex: if ex.errno != errno.ENOENT: raise # it doesn't existelse: # it does and it's open

     Also, for converting strings to integers.

     try: i = int(s)except ValueError: print "Not an integer! Please try again." sys.exit(1)

     Even importing optional modules...

     try: import readlineexcept ImportError: pass

     The LBYL way

     The hasattr method, of course, works too. This technique is called "look before you leap", or LBYL for short.

     # Cached attributeif not hasattr(self, 'big_object'): big_object = CreateBigObject() self.big_object = CreateBigObject()big_object.do_something()

     (The hasattr builtin actually behaves strangely in Python versions prior to 3.2 with regard to exceptions -- it will catch exceptions that it shouldn't -- but this is probably irrelevant, since such exceptions are unlikely. The hasattr technique is also slower than try/except, but you don't call it often enough to care and the difference isn't very big. Finally, hasattr isn't atomic so it could throw AttributeError if another thread deletes the attribute, but this is a far-fetched scenario and you'll need to be very careful around threads anyway. I don't consider any of these three differences to be worth worrying about.)

     Using hasattr is much simpler than try/except, as long as all you need to know is whether the attribute exists. The big issue for me is that the LBYL technique looks "strange", since as a Python programmer I'm more used to reading the EAFP technique. If you rewrite the above examples so that they use the LBYL style, you get code that is either clumsy, outright incorrect, or too difficult to write.

     # Seems rather fragile...if re.match('^(:?0|-?[1-9][0-9]*)$', s): i = int(s)else: print "Not an integer! Please try again." sys.exit(1)

     And LBYL is sometimes outright incorrect:

     if os.path.isfile('some_file'): # At this point, some other program could # delete some_file... f = open('some_file', 'r')

     If you want to write a LBYL function for importing optional modules, be my guest... it sounds like the function would be a total monster.

     The getattr way

     If you just need a default value, getattr is a shorter version of try/except.

     x = getattr(self, 'x', default_value)-

     If the default value is expensive to construct, then you'll end up with something like this:

     x = getattr(self, 'attr', None)if x is None: x = CreateDefaultValue() self.attr = x

     Or if None is a possible value,

     sentinel = object()-x = getattr(self, 'attr', sentinel)if x is sentinel: x = CreateDefaultValue() self.attr = x

     Conclusion

     Internally, the getattr and hasattr builtins just use try/except technique (except written in C). So they all behave the same way where it counts, and picking the right one is due to a matter of circumstances and style.

     The try/except EAFP code will always rub some programmers the wrong way, and the hasattr/getattr LBYL code will irk other programmers. They're both correct, and there's often no truly compelling reason to pick one or the other. (Yet other programmers are disgusted that you would consider it normal for an attribute to be undefined, and some programmers are horrified that it's even possible to have an undefined attribute in Python.)

     Dio is a powerful HTTP client for Dart. It has support for interceptors, global configuration, FormData, request cancellation, file downloading, and timeout, among others. Flutter offers an http package that’s nice for performing basic network tasks but is pretty daunting to use when handling some advanced features. By comparison, Dio provides an intuitive API for performing advanced network tasks with ease.
