  • Stack allocation fails and heap allocation succeeds!! Is it possible??

    - by Prabhu
    Hello All, I have the following piece of snippet Class Sample { Obj_Class1 o1; Obj_Class2 o2;}; But the size of Obj_Class1 and Obj_Class2 is huge so that the compiler shows a warning "Consider moving some space to heap". I was asked to replace Obj_Class1 o1 with Obj_Class1* o1 = new Obj_Class1(); But I feel that there is no use of making this change as heap allocation will also fail if stack allocation fails. Am I correct? Or does it make sense to make this change ( other than suppressing the compiler warning ).

  • Eclipse autocompletion problem

    - by Gene Marin
    Just installed Eclipse Helios (Win7 64) and I'm having a strange problem. I type syso-Ctrl-Space which is expected to complete to System.out.println("") but it doesn't work! I searched the web for about an hour now, I set Preferences Java Editor Content Assist to defaults, nothing. Everything else seems to work. Ideas? To be clear: the shortcut works, it completes everything except "syso" as seen so far, on syso (also tried sysout) it says "No Default Proposals". I couldn't find this kind of shortcuts in the Content Assist, but I set them to default anyway.

  • Import a Collada model doesn't align to pixels

    - by Dan Friedman
    Assume I have a model that is simply a cube. (It is more complicated than a cube, but for the purposes of this discussion, we will simplify.) So when I am in Sketchup, the cube is Xmm by Xmm by Xmm, where X is an integer. I then export the a Collada file and subsequently load that into threejs. Now if I look at the geometry bounding box, the values are floats, not integers. So now assume I am putting cubes next to each other with a small space in between say 1 pixel. Because screens can't draw half pixels, sometimes I see one pixel and sometimes I see two, which causes a lack of uniformity. I think I can resolve this satisfactorily if I can somehow get the imported model to have integer dimensions. I have full access to all parts of the model starting with Sketchup, so any point in the process is fair game. Is it possible? Thanks.

  • Forcing images to not wrap

    - by Mohammad
    I can't touch the html theme but I have access to the css files. <div class="photos"> <img src="a.jpg" alt="" align="left" /> <img src="b.jpg" alt="" align="left" /> <img src="c.jpg" alt="" align="left" /> //align makes the images wrap </div> Unfortunately I can't remove align="left" from the images otherwise this CSS snippet would have done the job .photos{ white-space: nowrap; } .photos img{ display: inline; vertical-align: top; } Any ideas? Is it even possible to make these images line-up horizontally without using the force of a table and only with CSS? Many Thank in advance!

  • Xcode: code loses syntax coloring

    - by ColorMeFamous
    I find that in various situations Objective-C code in Xcode 3.1 (Leopard) can fail to get appropriate syntax coloring after typing or lose coloring that it had. This isn't just a "refresh" issue with new custom symbols -- but affects Cocoa framework symbols as well. Sometimes CMD-a to select all text on the code page will make the coloring (re)appear, sometimes double-clicking on a line to select it will work, sometimes I have to add/delete a space in a symbol to get that symbol to (re)color. Rebuilding, or closing/reopening the project may or may not work. Is this a known issue with Xcode? For something so annoying to me, I'm not finding the plentiful discussions of it on SO and elsewhere I'd expect. And is there any command to force global syntax recoloring?

    - by Kabeer
    Hello. I am a consultant and will be working with geographically distant clients. I am looking for a solution to collaborate with my clients effectively in all the phases of the projects (architecture, requirements, design, construction, testing, deployment, maintenance). My hunt is for something in the open source (and preferably free) space and also on .Net platform. I need to record my communication with the clients and with growing no. of clients I should not miss out capturing any information. Please recommend.

  • margin between content and div overflow scrollbar

    - by ben
    I am using the following bits of code to keep my menu items fixed while allowing for the scrolling of content because it seems to be the most stable method across all browsers. body { overflow: hidden; } div.content { height: 100%; overflow: auto; } My problem is simple, and yet I can not seem to figure it out, the content inside the tag butts up against the scrollbar for the div area and it makes reading much more difficult. How can I get a margin between them (apart from floating a transparent image to the right to create space, there HAS to be a better way)?

  • With Eclipse, in a PHP project with SVN, how to "tell" Eclipse to find autocompletion choice only in

    - by ranskalainen
    Hello, Using Eclipse on a PHP Project, I recently created a tag on my SVN. Since that day, let's say I'm working on a class in my trunk, when I ctrl+space in my code, Eclipse is getting really really slow (sometimes even freeze), and if I'm lucky, it will give me 2 responses for autocompletion : One referencing some method/class from the tag, one referencing method/class from the trunk. But right now, only the reference from the trunk would be useful for me. Is there a way to limit where Eclipse parse the code to give back autocompletion suggestion ? Thank you

  • Is there a way to only backup a SQL 2005 database structure fully, but only the data in a certain se

    - by TheSoftwareJedi
    I have several schemas in my database, and the largest one ("large" meaning disk space consumed) is my "web" schema which is a denormalized copy of data in the operational schemas. This denormalized data is able to be reconstructed at anytime, and is merely there for extremely fast read purposes. Since the data is redundant, and VERY large - I'd like to exclude it from being backed up. I already have stored procedures that can regenerate all of the data in that schema in a couple of hours - for use in the event of a failure. I assume I can split the tables in this schema out to another data file or such (ideally even on another drive for faster reads), but is there a way to never have that data file backup, yet still in the event of a failure its structure could be restored (and other DDL stuff like procs, views, etc)? Somewhat related, can I also have these tables not do transaction logging, if I go to "Full" backup mode for the rest of the database?

  • Does Google App Engine allow creation of files and folders on the server ?

    - by Frank
    I know Google App Engine offers free space, but I wonder if it's for storing data in it's database only or does it also allow me to create files and directories on the server side to store my data ? For instance can I use the following method to save file ? public static void saveFile(String File_Path,StringBuffer Str_Buf,boolean Append) { FileOutputStream fos=null; BufferedOutputStream bos=null; try { fos=new FileOutputStream(File_Path,Append); bos=new BufferedOutputStream(fos); for (int j=0;j<Str_Buf.length();j++) bos.write(Str_Buf.charAt(j)); } catch (Exception e) { e.printStackTrace(); } finally { try { if (bos!=null) { bos.close(); bos=null; } if (fos!=null) { fos.close(); fos=null; } } catch (Exception ex) { ex.printStackTrace(); } } } Frank

  • Removing a character from a string

    - by Prasanth Madhavan
    i have a string. I want to delete the last character of the string if it is a space. i tried the following code, str.erase(remove_if(str.begin(), str.end(), isspace), str.end()); but my g++ compiler gives me an error saying: error: no matching function for call to ‘remove_if(__gnu_cxx::__normal_iterator<char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, __gnu_cxx::__normal_iterator<char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, <unresolved overloaded function type>)’ please help.

  • How to add a margin to a CheckedListBox in .NET?

    - by Xanatos
    I'm writing an windforms application using .NET (actually IronPython, but that's not relevant), and I have a CheckedListBox object in my GUI. It's working fine, it has about 20 items in a multicolumn layout. But I can't figure out how to give the thing a nice internal margin--I want to insert around 20 or 30 pixels of whitespace around the top, bottom, left, and right edges of the checkboxes. To be clear, I want the whitespace to appear between the border of the CheckedListBox and the Checkboxes inside it, not outside the whole component. Hopefully this is an easy answer, and I'm just missing it cause I'm new to programming in windows. If its not possible, I guess that'd be good to know too, so I don't waste anymore time with it. (If I were doing this in Swing (Java) I would be looking to set the Insets on my component, or maybe build up a compound border with some empty space in it.)

  • Caesar Cipher in Java (Spanish Characters)

    - by Rodolfo
    I've reading this question, and I was wondering if Is there any way to consider the whole range of characters? For example, "á", "é", "ö", "ñ", and not consider " " (the [Space])? (For example, my String is "Hello World", and the standard result is "Khoor#Zruog"; I want to erase that "#", so the result would be "KhoorZruog") I'm sure my answer is in this piece of code: if (c >= 32 && c <= 127) { // Change base to make life easier, and use an // int explicitly to avoid worrying... cast later int x = c - 32; x = (x + shift) % 96; chars[i] = (char) (x + 32); } But I've tried some things, and it didn't work.

  • Realtime Twitter Replies?

    - by ejunker
    I have created Twitter bots for many geographic locations. I want to allow users to @-reply to the Twitter bot with commands and then have the bot respond with the results. I would like to have the bot reply to the user as quickly as possible (realtime). Apparently, Twitter used to have an XMPP/Jabber interface that would provide this type of realtime feed of replies but it was shut down. As I see it my options are to use one of the following: REST API This would involve polling every X minutes for each bot. The problem with this is that it is not realtime and each Twitter account would have to be polled. Search API The search API does allow specifying a "-to" parameter in the search and replies to all bots could be aggregated in a search such as "-to bot1 OR -to bot2...". Though if you have hundreds of bots then the search string would get very long and probably exceed the maximum length of a GET request. Streaming API The streaming API looks very promising as it provides realtime results. The API allows you to specify a follow and track parameters. follow is not useful as the bot does not know who will be sending it commands. track allows you to specify keywords to track. This could possibly work by creating a daemon process that connects to the Streaming API and tracks all references to the bot's names. Once again since there are lots of bots to track the length and complexity of the query may be an issue. Another idea would be to track a special hashtag such as #botcommand and then a user could send a command using this syntax @bot1 weather #botcommand. Then by using the Streaming API to track all references to #botcommand would give you a realtime stream of all the commands. Further parsing could then be done to determine which bot to send the command to. Third-party service Are there any third-party companies that have access to the Twitter firehouse and offer realtime data? I haven't investigated these, but here are a few that I have found: Gnip Tweet.IM excla.im TwitterSpy - seems to use polling, not realtime I'm leaning towards using the Streaming API. Is there a better way to get near realtime @-replies for many (hundreds) of Twitter accounts?

  • Convert Eregi_replace to preg_replace in PHP

    - by alexy13
    I need help converting eregi_replace to preg_replace (since in PHP5 it's depreciated): function makeClickableLinks($text) { $text = eregi_replace('(((f|ht){1}tp://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)', '<a href="\\1">\\1</a>', $text); $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)', '\\1<a href="http://\\2">\\2</a>', $text); $text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})', '<a href="mailto:\\1">\\1</a>', $text); return $text; } (It turns text links and emails into hyperlinks so that the user can click on them)

  • NTFS-compressing Virtual PC disks (on host and/or guest)

    - by nlawalker
    I'm hoping someone here can answer these definitively: Does putting a VHD file in an NTFS-compressed folder on the host improve performance of the virtual machine, diminish performance, or neither? What about using NTFS compression within the guest? Does using compresssion on either the host or the guest lead to any problems like read or write errors? If I were to put a VHD in a compressed folder on the host, would I benefit from compacting it? I've seen references to using NTFS compression on quite a few VPC "tips and tricks" blog posts, and it seems like half of them say to never do it and the other half say that not only does it save disk space but it actually can improve performance if you have a fast CPU and your primary performance bottleneck is the disk.

  • Database query optimization

    - by hdx
    Ok my Giant friends once again I seek a little space in your shoulders :P Here is the issue, I have a python script that is fixing some database issues but it is taking way too long, the main update statement is this: cursor.execute("UPDATE jiveuser SET username = '%s' WHERE userid = %d" % (newName,userId)) That is getting called about 9500 times with different newName and userid pairs... Any suggestions on how to speed up the process? Maybe somehow a way where I can do all updates with just one query? Any help will be much appreciated! PS: Postgres is the db being used.

  • Code Golf: Phone Number to Words

    - by Nick Hodges
    Guidelines for code-golf on SO We've all seen phone numbers that are put into words: 1-800-BUY-MORE, etc. What is the shortest amount of code you can write that will produce all the possible combinations of words for a 7 digit US phone number. Input will be a seven digit integer (or string, if that is simpler), and assume that the input is properly formed. Output will be a list of seven character strings that For instance, the number 428-5246 would produce GATJAGM GATJAGN GATJAGO GATJAHM GATJAHN GATJAHO and so on..... Winning criteria will be code from any language with the fewest characters that produce every possible letter combination. Additional Notes: To make it more interesting, words can be formed only by using the letters on a North American Classic Key Pad phone with three letters per number as defined here.That means that Z and Q are excluded. For the number '1', put a space. For the number '0', put a hyphen '-' Bonus points awarded for recognizing output as real English words. Okay, not really. ;-)

  • Why is this leaking memory? UIImage `cellForRowAtIndexPath:`

    - by Emil
    Hey. Instruments' Leaks tells me that this UIImage is leaking: UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@.png", [postsArrayID objectAtIndex:indexPath.row]]]]; // If image contains anything, set cellImage to image. If image is empty, try one more time or use noImage.png, set in IB if (image != nil){ // If image != nil, set cellImage to that image cell.cellImage.image = image; } image = nil; [image release]; (class cell (custom table view cell) also releases cellImage in dealloc method). I haven't got a clue of why it's leaking, but it certainly is. The images gets loaded multiple times in a cellForRowAtIndexPath:-method. The first three cells' image does not leak (130px high, all the space avaliable). Leaks gives me no other info than that a UIImage allocated here in the code leaks. Can you help me figure it out? Thanks :)

  • How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

    - by moogeek
    Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

  • Algorithm for Source Control System?

    - by Michael Stum
    I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

  • Design Technique: How to design a complex system for processing orders, products and units.

    - by Shyam
    Hi, Programming is fun: I learned that by trying out simple challenges, reading up some books and following some tutorials. I am able to grasp the concepts of writing with OO (I do so in Ruby), and write a bit of code myself. What bugs me though is that I feel re-inventing the wheel: I haven't followed an education or found a book (a free one that is) that explains me the why's instead of the how's, and I've learned from the A-team that it is the plan that makes it come together. So, armed with my nuby Ruby skills, I decided I wanted to program a virtual store. I figured out the following: My virtual Store will have: Products and Services Inventories Orders and Shipping Customers Now this isn't complex at all. With the help of some cool tools (CMapTools), I drew out some concepts, but quickly enough (thanks to my inferior experience in designing), my design started to bite me. My very first product-line were virtual "laptops". So, I created a class (Ruby): class Product attr_accessor :name, :price def initialize(name, price) @name = name @price = price end end which can be instantiated by doing (IRb) x = Product.new("Banana Pro", 250) Since I want my virtual customers to be able to purchase more than one product, or various types, I figured out I needed some kind of "Order" mechanism. class Order def initialize(order_no) @order_no = order_no @line_items = [] end def add_product(myproduct) @line_items << myproduct end def show_order() puts @order_no @line_items.each do |x| puts x.name.to_s + "\t" + x.price.to_s end end end that can be instantiated by doing (IRb) z = Order.new(1234) z.add_product(x) z.show_order Splendid, I have now a very simple ordering system that allows me to add products to an order. But, here comes my real question. What if I have three models of my product (economy, business, showoff)? Or have my products be composed out of separate units (bigger screen, nicer keyboard, different OS)? Surely I could make them three separate products, or add complexity to my product class, but I am looking for are best practices to design a flexible product object that can be used in the real world, to facilitate a complex system. My apologies if my grammar and my spelling are with error, as english is not my first language and I took the time to check as far I could understand and translate properly! Thank you for your answers, comments and feedback!

  • Dynamic Spacer in ReportLab

    - by ptikobj
    I'm automatically generating a PDF-file with Platypus that has dynamic content. This means that it might happen that the length of the text content (which is directly at the bottom of the pdf-file) may vary. However, it might happen that a page break is done in cases where the content is too long. This is because i use a "static" spacer: s = Spacer(width=0, height=23.5*cm) as i always want to have only one page, I somehow need to dynamically set the height of the Spacer, so that it takes the "rest" of the space that is on the page as its height. Now, how do i get the "rest" of height that is left on my page?

  • Windows Azure Table Storage LINQ Operators

    - by Ryan Elkins
    Currently Table Storage supports From, Where, Take, and First. Are there plans to support any of the other 29 operators? If we have to code for these ourselves, how much of a performance difference are we looking at to something similar via SQL and SQL Server? Do you see it being somewhat comparable or will it be far far slower if I need to do a Count or Sum or Group By over a gigantic dataset? I like the Azure platform and the idea of cloud based storage. I like Windows Azure for the amount of data it can store and the schema-less nature of table storage. SQL Azure just won't work due to the high cost to storage space.
