Just curious,
Is there any difference between calling len([1,2,3]) or [1,2,3].__len__() ? If there is no apparent difference, what is done differently behind the scenes?
Thanks
Has anyone played around with the architecture tools (uml diagrams, etc) in VS 2010 and if so what is your opinion? I really am liking Sparx Systems Enterprise Architect but am also curious about what is available in VS 2010. I'm not looking for responses about how much you hate Microsoft tools or love mircosoft tools, but more for answers about how useful VS2010 arc tools are for you.
Is there any practical difference between these two extension methods?
class Extensions
{
public static void Foo<T>(this T obj) where T : class { ... }
public static void Foo(this object obj) { ... }
}
I was poking around in Extension Overflow and I came across the first form, which I haven't used before. Curious what the difference is.
I'm curious about infinite numbers in computing, in particular pi.
For a computer to render a circle it would have to understand pi. But how can it if it is infinite?
Am I looking too much into this? Would it just use a rounded value?
I'm doing some initial research on smart phone development, and I noticed that Android and Windows Mobile both support c++ for application development. I was curious if anyone had any experience trying to manage shared files between both Android and Windows Mobile, and to what extent that code can be shared? e.g. no user interface can be shared, but web service and business logic classes can be shared, etc.
Hi,
I have a question about how to store the assembly language in memory,when I compile the C-code in assembly, and run by "step", I can see the address of each instruction, but is there a way to change the start address of the code in the memory?
Second question is, can I break the assembly code into two?
I am curious about how the machine store the assembly code.
BTW, I am working on a MACBOOK Pro, duo core.
Thank you.

Hi! Got the following warning output when using GCC 4.5.0 & MinGW.
Warning: .drectve `-aligncomm:___CTOR_LIST__,2 ' unrecognized
Warning: .drectve `-aligncomm:___DTOR_LIST__,2' unrecognized
What does it mean? I guess it's version-specific, because GCC 4.3.4 under cygwin didn't give that warning on the same project.
If anyone had the following output (just curious that's that about), please advise me what to do.
Hi all,
I was curious to know how I can round a number to the nearest tenth. For instance If I had
int a = 59 / 4 /* which would be 14.75 and how can i Store the number as 15 in "a"*/
Thanks,
Dave
Currently Buildbot does not support multiple repositories. If one desires to have this then separate instances of Buildbot need to be run.
Still I'm curious if anyone has come up with a creative workaround to get this feature working anyway.
Hi!
I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU.
Thanks in advance, C gurus ;o)
I have a simple index page for clients. Client has 20 fields. I am displaying list of clients in a table. For this I have to write in my views something like:
- @clients.each do |client|
%tr
%td=client.name
%td=client.email
%td=client.address
%td=client.phone etc...
I am just curious if I can do it something like
- @clients.each do |client|
- client do
%tr
%td= name
%td= email
%td= address
%td= phone etc...
I have three tables with a common key field, and I need to join them on this key. Given SQLite doesn't have full outer or right joins, I've used the full outer join without right join technique on Wikipedia with much success.
But I'm curious, how would one use this technique to join three tables by a common key? What are the efficiency impacts of this (the current query takes about ten minutes)?
Thanks!
I was hoping someone could explain why my application when loaded uses varying amounts of RAM. I'm speaking about a compiled version that uses the exe directly. It's a pretty basic applications and there are no conditional branches in the startup of the application. Yet every time I start it up the RAM amount varies from 6MB-16MB.
I know it's on the small end of usage anyways but I'm curious of why this happens.
I am writing a custom error handling/reporting function for php file upload and I noticed that the error codes returned is one of numbers 0 to 8 except 5.
Is this a typo in the source I am using or is it really this way? And if it is so, I am curious why they have skipped number '5'.
Thanks.
I am looking for some direction on how to render a barcode from a numeric string on an iPhone? The symbology is not really important right now just curious on the basics or third party support if necessary.
Thanks in advance.
I'm curious if anyone has done any performance comparisons with any or all of the main players in the .NET ORM space. Specifically I'm interested in comparisons between the following:
Linq to SQL
NHibernate
LLBL Gen
Entity Framework
Though it seems people don't really consider Linq to SQL a true ORM, I am still including it in this list. Some performance metrics would be nice to see.
Given a 1*N matrix or an array, how do I find the first 4 elements which have the same value and then store the index for those elements?
PS:
I'm just curious. What if we want to find the first 4 elements whose value differences are within a certain range, say below 2? For example, M=[10,15,14.5,9,15.1,8.5,15.5,9.5], the elements I'm looking for will be 15,14.5,15.1,15.5 and the indices will be 2,3,5,7.
This question is, as indicated, for those who use Emacs.
When you do, do you rebind the caps-lock key to CTRL, or do you use the "normal" ctrl key?
I've recently learned some Emacs commands and was using the Visual Studio 2008 emacs commands for a while, and of course I used a caps-rebind tool, but I'm curious how many other people do.
On a side note, the emacs bindings for VS are severely incomplete :(
Community wiki'ed already, folks.
What part of Apache Commons saves you the most time?
I'm curious to get together a list of these to browse and see what I don't know about, or what I should be using more often than not.
i have this python script where i need to run 'gdal_retile.py'
but i get this an exception on this line:
if Verbose:
print(Building internam Index for %d tile(s) ..." % len(inputTiles), end=' ')
the end='' is invalid syntax just curious as to why.. and what the author probably meant to do.
I'm new to python if you haven't already guessed.
I'm curious if anyone still creates icons other than RGB/A (or 32-bit with alpha-channel) for your Windows apps?
PS. I know that suggested model is to create 256-color versions of icons, but I always struggle with those. If I automatically convert them in an icon editor they totally decimate the look of my original icons with jagged edges and circa-Windows95 look. So if those are still required, does anyone know the stats on how many people are still using color settings other then 32-bit TrueColor?
My company is preparing to post some job postings for a programmer (or two) and am curious as to what experiences any of you have had with the big three job posting providers (Monster, CareerBuilder, HotJobs). Are there others out there that we don't know about that might be better? Any thoughts/insights would be appreciated!
1 - Curious as to how to make a popup asking to confirm if I want to load the program before it loads. Example:
^g::Run C:\GW2\gw2.exe
2 - How to set a title(instead of the script name), align text within msgbox and control the perimeters of msgbox with this format:
F1::msgbox,
(LTrim
Insert Text Here
)
3 - How to either temporarily pause and unpause a specific AHK script only allowing that hotkey to work within the script OR to disable scripted hotkeys while in a full screen application or game OR a "on/off pause/resume" command to disable multiple other commands such as ^g, ^h and the like.
Hi.
Scala implicits are very powerfull. I'm curious if they are a new/unique feature of Scala, or the concept already existed in other programming languages.
Thanks.
Note: I have used the tag "implicit" instead of "implicits" because it doesn't exists and I can't create new tags...
I found a post from a while ago that addresses a similar question but I think it's a bit outdated. I realize implementations of JPA tend to be more on the heavy/dense side, so if you know of any lightweight (non-JPA) ORMs I'll most certainly appreciate your input. I did see the answer about ActiveAndroid in the other post and am curious to know if anyone tried it out.
