• How does browser search tool work on web page?

  - by GTM

  I am trying to figure out how the search tool in a web browser is being able to parse through the entire web page(assuming huge content on a page) and highlight the result as we type. Does it pre-cache the page while loading in a map or use regex to get a quick result on the fly?

• Gzip In-Memory Compression

  - by feal87

  Quick and simple question. There are examples online about achieving in-memory gzip compression with zlib (C++) WITHOUT external libraries (like boost or such)? I just need to compress and decompress a block of data without much options. (it must be gzip as its the same format used by another mine C# program (the data is to be shared)) Tried to search to no avail... Thanks!

• Groups equivalent for social plugin Facepile

  - by oivvio

  I need to do something similar to the Facepile social plugin for a site I'm working on. The problem is the client does not have have a Facebook page, but instead has a Facebook Group (with some 4000+ members). I guess I could urge the client to move their group members to a page, and I might do that in the future. But before I do I want to research how we're going to do Facebook-integration more thoroughly. For now I just need a quick fix.

• which text writing classes are the most efficient for writing lots of small files?

  - by Robert H

  I have to write 300+ files to a server share on a hourly basis. A quick implementation using CreateText takes approximately 1.4 seconds per file. I know there is a better way to do this, but I am unsure which way is actually the quickest/most efficient; hence my question: Which text writing class is the most efficient for writing hundreds of small files ( 336 bytes on average ) to a server share?

• Python 3: list atributes within a class object

  - by MadSc13ntist

  is there a way that if the following class is created; I can grab a list of attributes that exist. (this class is just an bland example, it is not my task at hand) class new_class(): def __init__(self, number): self.multi = int(number) * 2 self.str = str(number) a = new_class(2) print(', '.join(a.SOMETHING)) * the attempt is that "multi, str" will print. the point here is that if a class object has attributes added at different parts of a script that I can grab a quick listing of the attributes which are defined.

• Are PHP5 objects passed by reference?

  - by morpheous

  I cant seem to get any consistent info on this. Different sources appear to say different things and trhe venerable php.net iteslf (appears) not to explicitly state this - although I must admit, I only had a quick look. In cases where I am passing around 'heavy' objects, I need to pass by reference, but I dont want to keep typing: function foo(TypeName& $obj) if I can get away with simply, function foo(TypeName $obj) So what does the standard say?

• Getting started with PHP on Windows

  - by jamesaharvey

  I'm getting started with a side project that will be developed using PHP and I'm looking for guidance on getting my Windows machine up and running and ready for development (as quickly as possible). Being that PHP development is more geared towards Linux users/developers (which I am not), I'm trying to figure out how to get all the pieces in place to get a 'WAMP' stack operational locally on my Windows machine. Any good tutorials/quick start guides out there and if not, does someone have all the steps that they could provide me with here?

• Need a fast test to see if a remote printer is available or not. Using CreateIC now, and when print

  - by Steve

  My application does a CreateIC (and later, an OpenPrinter) for the user's default printer. When this is a remote printer, and that printer is powered down or otherwise not present on the network, it takes over 20 seconds for the CreateIC to return. I'm looking for some call I can make that will give me a quick answer if the server is down (so I can return a status and not try to do the CreateIC/OpenPrinter). My environment is c/c++ (non-managed).

• Are there any C++ style and/or standard example files available?

  - by Harvey

  While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

• Blittable Vs. Non-Blittable in IL

  - by Michael Covelli

  I'm trying to make sure that my Managed to Unmanaged calls are optimized. Is there a quick way to see by looking at the IL if any non-blittable types have accidentally gotten into my pinvoke calls? I tried just writing two unmanaged functions in a .dll, one that uses bool (which is non-blittable) and one that uses ints. But I didn't see anything different when looking at the IL to let me know that it was doing something extra to marshal the bool.

• Magento CSS not Loading in New Template

  - by vulgarbulgar

  I have posted on the template creator's site, as well as Magento support, but no one has responded. The CSS is not loading at all on the custom theme I have installed, which is supposedly compatible with the current version of Magento. You can view the page here: shop.dearearth.net This is a fresh installation of Magento and the theme, with a fresh database. I have a feeling it should be a relatively quick fix. Thanks for looking.

• Why save output until the end?

  - by user509006

  Very quick question about programming practices here: I've always used echo() to output HTML code to the user as soon as it was generated, and used ob_start() at the same time to be able to output headers later in the code. Recently, I was made aware that this is bad programming practice and I should be saving HTML output until the end. Is there a reason for this? What is it, and why isn't output buffering a good alternative? Thanks!
