• CSS not displayed depending on page

  - by Kanjiroushi

  I have a friend that has a really strange issue with my website. When he clicks on http://www.copeo.fr/ the page displays fine but when he clicks on a link like www.copeo.fr/user/ the CSS is not applied even after a refresh. The raw html does display. I asked him to display the CSS that is hosted on amazon S3 hcopeoressources.s3.amazonaws.com/style/futurvert/style.css and it displays fine. The code validates on W3C validator so does the CSS. I am lost what could be the origin of the issue. Could it be its enterprise cache? configuration of IE7 on his machine? If it happens to someone else who could explain the issue to me, I am all hears. Thanks

• sequentially-consistent atomic load on x86

  - by axe

  Hello all, I'm interested in sequentially-consistent load operation on x86. As far as I see from assembler listing, generated by compiler it is implemented as a plain load on x86, however plain loads as far as I know guaranteed to have acquire semantics, while plain stores are guaranteed to have release. Sequentially-consistent store is implemented as locked xchg, while load as plain load. That sounds strange to me, could you please explain this in details? added Just found in internet, that sequentially-consistent atomic load could be done as simple mov as long as store is done with locked xchg, but there was no prove and no links to documentation. Do you know where can I read about that? Thanks in advance.

  - by Haiyuan Zhang

  let's say there two modules mutualy use each othe as: package a; use b; sub p {} 1; package b; use a; 1; I think symatically it's wrong to wrote code like the above code, cus the two modules will endlessly copy each other's code to themselves...but I can successfully run the following code, which makes me very surprised. so could any of you explain all of this to me? #! /usr/bin/perl use a; a->p();

I have used distinct but it's not working, n I need data to be sum still not working. Here is my query, can somebody explain what's wrong? var report= (from u in myDb.TBL_TRANSAKSI_MKN_MNMs.AsEnumerable() where u.TGL_TRANSAKSI.Value.Date.Equals(dateTimePicker1.Value.Date) join l in myDb.TBL_DETAIL_TRANSAKSIs.AsEnumerable() on u.ID_NOTA equals l.ID_NOTA join m in myDb.TBL_MKN_MNMs.AsEnumerable() on l.ID_MKN_MNM equals m.ID_MKN_MNM group new { u, l, m } by new { m.NAMA_MKN_MNM, m.HARGA_JUAL, u.TGL_TRANSAKSI, l.ID_MKN_MNM, u.USERNAME, l.Jumlah } into grp select new { MakanMinum = grp.Key.NAMA_MKN_MNM, HargaJual = grp.Key.HARGA_JUAL, Stok = grp.Sum(groupedthing => groupedthing.l.Jumlah), Tanggal = grp.Key.TGL_TRANSAKSI, Jumlah =(grp.Key.HARGA_JUAL * grp.Sum(groupedthing => groupedthing.l.Jumlah)), Total = grp.Sum(grouptotal => grp.Key.HARGA_JUAL * grp.Sum(groupedthing => groupedthing.l.Jumlah)), Username = grp.Key.USERNAME }).Distinct();

• CSS Sprites : Mysterious Concept Explored ?

  - by Rachel

  I have 3 different images and now I want to create an sprite using css so that I am reducing HTTP Request. I am totally new to this concept and have not idea as to how to approach this. Can anyone suggest me what would be best bet for me ? Also I have seen there are some CSS Sprite generator engines where in you submit .zip folder containing your images and than they would combine it. I tried doing that but did not understood of what was happening and so any guidance regarding creating and using CSS sprites would be highly appreciated. Update: I have gone through the AList Part but it was not very clear to me. Can anyone explain the use case of CSS Sprites using an example ? Thanks.

• Weird behavior in referring to global variable. Is this a bug in javascript? Surely it isn't!

  - by Chandan .

  Consider the following piece of code. <html> <body> <script> var x = 5; //globally declared function showX() { alert("x="+x); //trying to display global value var x=10; //trying to create and initialize a local x } </script> <input type = "button" value="Show X" onclick="showX()"> </body> </html> The alert statement shows 'x=undefined'. And doesn't print the global value of x as expected. An equivalent java code would display 5! So, is it a bug? If not then how does one explain that behavior?

• What is the difference between an object's scope and it's context in javascript?

  - by DKinzer

  In the vernacular, scope and context have a lot in common. Which is why I get confused when I read references to both, such as in the quote below from an article on closures: Scope refers to where variables and functions are accessible, and in what context it is being executed. (@robertnyman) As far as I can tell, context is just a reference to an object. Can someone please explain what exactly is context, as used, for instance, in the jQuery syntax, $(selector, context). And is an object's scope the same at it's context?

• List in a Python class shares the same object over 2 different instances?

  - by zfranciscus

  I created a class: class A: aList = [] now I have function that instantiate this class and add items into the aList. note: there are 2 items for item in items: a = A(); a.aList.append(item); I find that the first A and the second A object has the same number of items in their aList. I would expect that the first A object will have the first item in its list and the second A object will have the second item in its aList. Can anyone explain how this happens ? PS: I manage to solve this problem by moving the aList inside a constructor : def __init__(self): self.aList = []; but I am still curious about this behavior

• C# Elegant way to handle checking for an item in a collection.

  - by JL

  I've posted a code sample below. Firstly let me explain termStore.Groups in the code below is a collection of Group Objects (The exact class is irrelevant). Checking for null : if (termStore.Groups[groupName] == null) seems like a logical (clean) approach, but if the Groups collection is empty then an exception is produced. using the termStore.Groups.Contains is not an option either because this expects a strong type i.e: .Contains(Group)... not .Contains(GroupName as string) Can someone recommend a clean / generic way I can check for if an item exists in collection . Thank you.... TermStore termStore = session.TermStores.Where(ts => ts.Name == termStoreName).FirstOrDefault(); if (termStore.Groups[groupName] == null) { termStore.CreateGroup(groupName); termStore.CommitAll(); } Update: The exact class Sharepoint Taxonomy Classes. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.taxonomy.group.aspx

I would like this function to be called with the appropiate index. Hope I explain myself, thanks in advance.

• Force reload/refresh when pressing the back button

  - by FlyingCat

  I will try my best to explain this. I have an application that show the 50+ projects in my view page. The user can click the individual project and go to the update page to update the project information. Everything works fine except that after user finish updating the individual project information and hit 'back' button on the browser to the previous view page. The old project information (before update) is still there. The user has to hit refresh to see the updated information. It not that bad, but I wish to provide better user experience. Any idea to fix this? Thanks a lot.

• How to use #ifdef entities as part of functions in header files

  - by Crazyjavahacking

  I would like to ask if it is possible to use the entities defined in #ifdef block in header files. To be clear, I have following code: #ifdef #include <winsock2.h> #define SOCKET_HANDLE SOCKET #define CONNECTION_HANDLE SOCKET #endif SOCKET_HANDLE createServerSocket(const char* hostAddress, short port); I am Java developer and this seems completely fine for me. However compiler has a problem with this. Can you explain why is that code a problem? Also how can I force to compile it. (The idea is to have generic interface and conditional compilation to determine real types according to running platform at compile time.) Thanks

• scaleX scaleY increasing left, top margin, and line spacing

  - by Mark

  If you have Text with a font that is 72 point for example (and scaleX scaleY = 1) you can achieve the same size with a font size of 12 and scaleX,scaleY = 6. For reasons that would take too long to explain I am applying a large scale factor as in the latter example. The problem is, even though the text is the same size, the line spacing and left and top margins have all been increased but I want them to be the same size as well. As far as the line spacing, I discovered that TextFormat.leading was being automatically increased when scaleX, scaleY was greater than 1, so I just had to reset TextFormat.leading back to 0. That leaves the left and top margins, and I have no idea how those are being increased. I tried TextFormat.blockIndent=0 and TextFormat.leftMargin=0 (and also ignorePadding=true) and it had no effect. And have no clue how to reset the top margin either to its orginal size, in case anyone has an idea for all these.

• Where does memory dynamically allocated reside?

  - by Summer_More_More_Tea

  Hello everyone: We know that malloc() and new operation allocate memory from heap dynamically, but where does heap reside? Does each process have its own private heap in the namespace for dynamic allocation or the OS have a global one shared by all the processes. What's more, I read from a textbook that once memory leak occurs, the missing memory cannot be reused until next time we restart our computer. Is this thesis right? If the answer is yes, how can we explain it? Thanks for your reply. Regards.

• Need some help in understanding SSL concepts

  - by user1115256

  I am new to SSL programming and finding some difficulties in understanding SSL concepts. I tried to get it through openssl site,but it is not much informative. Here is my doubts. What is difference between SSL Buffer and BIO buffer..? I mean layerwise detail will be very helpful. Can I use SSL_Write and SSL_Read without setting any BIO object to SSL object..? What exactly BIO_flush will do... I mean is it going to flush all the data to network buffer from BIO buffer.. ? If it is possible to do write and read data from SSL directly without using any BIO object then is it possible to flush the data from SSL buffer to network buffer by any means.. ? It would be very helpful if any body explain these things or giving any links where I can find answers to my questions.

• Windows Service Printing Behaviour

  - by Andre

  Alright, I was tasked to develop a Windows Service that listens to a directory for files that are dropped in it, read them, delete them and print out a report. I installed the service on my work laptop (Win 7 x86) and a test machine (XP x86) under a User account at first. It would do everything as it should except the print the report. No errors, nothing. Then I made it run under Local System and it produced a "No printers found" exception. Converting the app to a Console Application and running on these machines gave the desired result. OK, so now I was assuming that there are security "stuff" involved. Then I installed the service on a Server 2008 x64 machine (under Local System) and it just worked. Can anybody explain to me why this is happening? Why does the service allow printing from Server OS but not from a Desktop OS or am I missing something very obvious?

• What is __path__ useful for?

  - by Jason Baker

  I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?

  Use big-O notation to classify the traditional grade school algorithms for addition and multiplication. That is, if asked to add two numbers each having N digits, how many individual additions must be performed? If asked to multiply two N-digit numbers, how many individual multiplications are required Suppose f is a function that returns the result of reversing the string of symbols given as its input, and g is a function that returns the concatenation of the two strings given as its input. If x is the string hrwa, what is returned by g(f(x),x)? Explain your answer - don't just provide the result!
