• How to verify if file is according to mask in PHP without reading filename from disk.

  - by php html

  I have a list of file names(I already have the filelist let's say in a text file). I want to process this list in the following way: filenames of type /dirX/subdirX//.ext will be written in a new file all the other filenames will be written in a separate file. Is there any option to verify if a filename corresponds to a mask, without reading the file name from disk?(by filename I mean a simple string). I would like to know if there is such a function that don't require disk access. I know regex could be an workaround but I'd like to have something from php.

• ASP.NET MVC Programming

  - by AlbertRosa

  So here's the deal I'm working on a project that I had originally focused on Zend Framework, But now I want to get into ASP.NET MVC and boy lets just say it's good and a great start though i'm still at the beginning stage of it. But I am having issues with passing Data From My Controller to the Master / Layout Page. Now in Zend I am able to determine which controller and which action I am in through a helper I created. Now I want to implement the same functionality in this ASP.NET MVC application. So my Master Layout Page knows which Controller I am in and hence highilighting the navigation for it. I am using a straight custom html li a structure navigation. Any help on this specific topic would be greatly appreciated.

• Organization of linking to external libraries in C++

  - by Nicholas Palko

  In a cross-platform (Windows, FreeBSD) C++ project I'm working on, I am making use of two external libraries, Protocol Buffers and ZeroMQ. In both projects, I am tracking the latest development branch, so these libraries are recompiled / replaced often. For a development scenario, where is the best place to keep libprotobuf.{a,lib} and zeromq.{so,dll}? Should I have my build script copy them from their respective project directories into my local project's directory (say MyProjectRoot/lib or MyProjectRoot/bin) before I build my project? This seems preferable to tossing things into /usr/local/lib, as I wouldn't want to replace a system-wide stable version with the latest experimental one. Cmake warns me whenever I specify a relative path for linking, so I would suspect copying is a better solution then relative linking? Is this the best approach? Thanks for your help!

• Is it good to commit files often if using Mercurial or Git?

  - by Jian Lin

  It seems that it is suggested we can commit often to keep track of intermediate changes of code we wrote… such as on hginit.com, when using Mercurial or Git. However, let's say if we work on a project, and we commit files often. Now for one reason or another, the manager wants part of the feature to go out, so we need to do a push, but I heard that on Mercurial or Git, there is no way to push individual files or a folder… either everything committed gets pushed or nothing get pushed. So we either have to revert all those files we don't want to push, or we just never should commit until before we push -- right after commit, we push?

• Razor support of generic extension methods

  - by Brian

  Hello, With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in: @Html.TextBoxFor<SomeModel>(i => i.Name) This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach? Thanks.

• How to reduce the number of cert validation requests... (IE is killing me slowly)

  - by scooterhanson

  On a customer's internal network, I can make a request to my SSL site using IE6 SP1 (on Win2K) and see one cert validation requests, but if I use IE6 SP2 (on XP) 13 separate cert validation requests get fired off. Needless to say, this slows down my page load a lot. Firefox loads the page just fine with no unnecessary cert validation requests. The server is Apache running a pretty new lampp stack. All the server certificate / CA chain configurations seem to be fine (users can authenticate w/ trusted certs, the system can communicate to other systems with that server cert, etc.) Is there anything I can do from a configuration standpoint? Any other ideas at all?

• Fulltext and composite indexes and how they affect the query

  - by Brett

  Just say I had a query as below.. SELECT name,category,address,city,state FROM table WHERE MATCH(name,subcategory,category,tag1) AGAINST('education') AND city='Oakland' AND state='CA' LIMIT 0, 10; ..and I had a fulltext index as name,subcategory,category,tag1 and a composite index as city,state; is this good enough for this query? Just wondering if something extra is needed when mixing additional AND's when making use of the fulltext index with the MATCH/AGAINST. Edit: What I am trying to understand is, what happens with the additional columns that are within the query but are not indexed in the chosen index (the fulltext index), the above example being city and state. How does MySQL now find the matching rows for these since it can't use two indexes (or can it?) - so, basically, I'm trying to understand how MySQL goes about finding the data optimally for the columns NOT in the chosen fulltext index and if there is anything I can or should do to optimize the query.

• Running Python code from Java program, shoudl i be doing this?

  - by Space Rocker

  i have a scenario where i draw a network and set all it's paraments on swing based gui, after that i have to translate this network into a python based script which another framework reads and realize this network in the form of virtual machines. As an example have look here: from mininet.topo import Topo, Node class MyTopo( Topo ): def *__init__*( self, enable_all = True ): super( MyTopo, self ).__init__() Host = 1 Switch = 2 self.add_node( Switch, Node( is_switch=True ) ) self.add_node( Host, Node( is_switch=False ) ) self.add_edge( Host, Switch ) self.enable_all() topos = { 'mytopo': ( lambda: MyTopo() ) } It simply connects a host to a switch and realize this topology on mininet framework. Now for now in order to realize the drawn network on java GUI here is what i am doing: I simply take the information from GUI and creates a new python file like the one above using java code and then run this file in mininet, which works fine somehow. I want to know, is this the correct and robust way how i am doing this or should i be looking further into java-python bridge like scenarios to be more effective or so as to say more professional.

• Fulltext for innoDB? or a good solution for php app

  - by Joshua

  I have a table I want to run a fulltext search on, but it is currently innoDB and is using a lot of foreign keys for other kinds of queries. Should I make like a 1:1 "meta-data" table that is myisam for fulltext? Also I am reading some things that say that fulltext corrupts MySQL tables pretty randomly? I dunno, the articles are a couple years old, maybe they've fixed that in 5+? If not what's a good solution for searching? Zend_Lucene seems cool but slow, even with caching, for the client's large tables and autocomplete functionality et al.

• using jquery to parse XML export in drupal

  - by gables20

  I need to use jquery to parse a drupal xml export that was created with views datasource module. The format of the xml export is shown below and on the browser, its access by entering, say for example, http://mydomain/test.xml, where test.xml represents the path of the xml export. <node> <node> <nothing> Lorem ipsum </nothing> </node> <node> The jquery to parse xml is shown below. But, it does nothing, which is kind of the main problem. $(document).ready(function(){ $.ajax({ type: "GET", url: "http://mydomain/test.xml", dataType: "xml", success: function(xml){ $(xml).find('node').each(function(){ var title = $(this).find('nothing').text(); $('#output').append($(this).find('nothing').text()); }); } }); });

• How can I find out how many rows of a matrix satisfy a rather complicated criterion (in R)?

  - by Brani

  As an example, here is a way to get a matrix of all possible outcomes of rolling 4 (fair) dice. z <- as.matrix(expand.grid(c(1:6),c(1:6),c(1:6),c(1:6))) As you may already have understood, I'm trying to work out a question that was closed, though, in my opinion, it's a challenging one. I used counting techniques to solve it (I mean by hand) and I finaly arrived to a number of outcomes, with a sum of subset being 5, equal to 1083 out of 1296. That result is consistent with the answers provided to that question, before it was closed. I was wondering how could that subset of outcomes (say z1, where dim(z1) = [1083,4] ) be generated using R. Do you have any ideas? Thank you.

• .NET connecting to oracle problems with the connectionstring

  - by Oxymoron

  At the moment I'm trying to make a connection to a local server. Connecting via, say, TOAD works fine. When I try to connect using .NET I get ora-12154. Which puzzles me, since I'm using the connectionstring from my TNSNAMES.ora file: XE = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = myPC)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE) ) ) As follows: private string connectionString = "Data Source=(DESCRIPTION =" +" (ADDRESS_LIST=(ADDRESS = (PROTOCOL = TCP)(HOST = myPC)(PORT = 1521)))" +" (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = XE));" +"User Id=sys;Password=zsxyzabc;"; Any ideas?

• How do I play flash files in pure C?

  - by CDR

  As part of a customized media player written in C (Win32), I need to enable my app play flash movies (.swf files) inside the player window. Can someone please indicate the most C compatible low level way to achieve this, giving me highest control? Specially control on display window and network access. I am looking for reference to a Windows DLL like flash_player.dll (if there is such thing) with documentation. Or at least a COM/ActiveX controls. Note that ActiveX is harder to use in C, than in say VB.

• HTML table with fixed cells size

  - by misha-moroshko

  I have an HTML table which has equally divided rows and columns. I would like each cell to be of a fixed size, say 40px width and 30px height. When I change the size of the browser window, the cells size changes also. How can I prevent it ? I would expect to see the scroll bars if browser's window become too small. Is that right to set the height and the width of the cell in pixels ? Thanks !

• Make Java parent class not part of the interface

  - by Bart van Heukelom

  (This is a hypothetical question for discussion, I have no actual problem). Say that I'm making an implementation of SortedSet by extending LinkedHashMap: class LinkedHashSortedMapThing extends LinkedHashMap implements SortedSet { ... } Now programmers who use this class may do LinkedHashMap x = new LinkedHashSortedMapThing(); But what if I consider the extending of LinkedHashMap an implementation detail, and do not want it to be a part of the class' contract? If people use the line above, I can no longer freely change this detail without worrying about breaking existing code. Is there any way to prevent this sort of thing, other than favouring composition over inheritance (which is not always possible due to private/protected members)?

• mysql LAST_INSERT_ID() used with multiple records INSERT statement

  - by bogdan

  Hello, If i insert multiple records with a loop that executes a single record insert, the last insert id returned is, as expected, the last one... but if i do a multiple records insert statement: INSERT INTO people (name,age) VALUES('William',25),('Bart',15),('Mary',12); let's say the three above are the first records inserted in the table...after the insert statement i expected last insert id to return 3, but it returned 1...the first insert id for the statement in question... So can someone please confirm if this is the normal behavior of LAST_INSERT_ID() in the context of multiple records INSERT statements...so i can base my code on it thanks :)

• Performance of: if (OBJECT_INSTANCE is TYPE)

  - by Axonn

  I am working both in C# and ActionScript 3. Both language are type-aware, so you can do verifications such as: if (some_object_instance is SomeClassName_ThatIs_SomeType) I'm doing these kind of verifications in a few places. Might be a dumb question, but I will ask it anyway, and I want answers from both camps, C# and ActionScript: What goes on behind the scenes? Is it Reflection? If is, isn't this a long verification which might degrade performance if done in thousands of loops? And by "degrade performance" I mean, is it more intensive than say if (Math.sqrt(8) > Math.sin(10))

• Caveats to be aware of when using threading in Python?

  - by knorv

  I'm quite new to threading in Python and have a couple of beginner questions. When starting more than say fifty threads using the Python threading module I start getting MemoryError. The threads themselves are very slim and not very memory hungry, so it seems like it is the overhead of the threading that causes the memory issues. Is there something I can do to increase the memory capacity or otherwise make Python allow for a larger number of threads? What is the maximum number of threads you've been able to run in your Python code using the threading module? Did you do any tricks to achieve that number? Are there any other caveats to be aware of when using the threading module?

• Is it better to use GL_FIXED or GL_FLOAT on Android.

  - by Timmmm

  I would have assumed that GL_FIXED was faster, but the iPhone docs actually say to use GL_FLOAT because GL_FIXED has to be converted to GL_FLOAT. Is it the same on Android? I suppose it varies by phone, but what about recent popular ones (Nexus One, Droid/Milestone, etc.)? Bonus points: This appears to be completely undocumented (e.g. search google for GL_FIXED!) but where is the 'point' in GL_FIXED? I.e. how much is (GL_FIXED)1 worth?

  HI there I am hoping for some help with a query I have. I have this query var group = from r in CustomerItem group r by r.StoreItemID into g select new { StoreItemID = g.Key, ItemCount = g.Count(), ItemAmount = Customer.Sum(cr => cr.ItemAmount),RedeemedAmount = Customer.Sum(x => x.RedeemedAmount) }; I am returning my results to a list so I can bind it listbox. I have a property called EntryType which is an int. There are 2 available numbers 1 or 2 Lets say I had 3 items that my query is working with 2 of them had the EntryType = 1 and the 3rd had EntryType2. The first records had a ItemAmount of 55.00 and the 3rd had a ItemAmount of 50.00 How can I group using something simlar to above but minus the ItemAmount of 50.00 from the grouped amount to return 60.00?
