• With vim, how can I use autocmd's for files in subdirectories of a specific path?

  - by René Nyffenegger

  I am trying to figure out how I can define an autocmd that influences all files under a specific path. The autocmd I have tried is something like autocmd BufNewFile,BufRead /specificPath/** imap <buffer> .... Now, I'd expect this autocmd to be used if I edited, say, /foo/bar/specificPath/baz/something/bla.txt, but not if I edited /foo/bar/here/and/there/moreBla.txt If I start vim being in a directory 'above' specificPath, this works as I want it. But it doesn't if I am below that directory. Obviously, the autocmd's pattern is matched against the relative file name, not the absolute one.

• What is the most frustrating programming style you've encountered?

  - by JaredPar

  When it comes to coding style I'm a pretty relaxed programmer. I'm not firmly dug into a particular coding style. I'd prefer a consistent overall style in a large code base but I'm not going to sweat every little detail of how the code is formatted. Still there are some coding styles that drive me crazy. No matter what I can't look at examples of these styles without reaching for a VIM buffer to "fix" the "problem". I can't help it. It's not even wrong, I just can't look at it for some reason. For instance the following comment style almost completely prevents me from actually being able to read the code. if (someConditional) // Comment goes here { other code } What's the most frustrating style you've encountered?

• Help using preg_match for phone numbers

  - by Kirk

  how would i write an if statement that would find phone numbers and store them to a variable. Here is what i have so far but its not working. if (preg_match('/^(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:\(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*\)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})(?:\s*(?:#|x\.?|ext\.?|extension)\s*(\d+))?$ /', $buffer, $matches)) { $phonenumber = html_entity_decode($matches[1]); }

• Boost ASIO read X bytes synchroniously into a vector

  - by xeross

  Hey, I've been attempting to write a client/server app with boost now, so far it sends and receives but I can't seem to just read X bytes into a vector. If I use the following code vector<uint8_t> buf; for (;;) { buf.resize(4); boost::system::error_code error; size_t len = socket.read_some(boost::asio::buffer(buf), error); if (error == boost::asio::error::eof) break; // Connection closed cleanly by peer. else if (error) throw boost::system::system_error(error); // Some other error. } And the packet is bigger then 4 bytes then it seems it keeps writing into those 4 bytes until the entire packet has been received, however I want it to fetch 4 bytes, then allow me to parse them, and then get the rest of the packet. Can anyone provide me with a working example, or at least a pointer on how to make it work properly ? Regards, Xeross

• QT Question - What are all these extra spaces for ? (pic provided)

  - by mea

  stack overflow wont let me post images so heres the link: http://4m0.org/images/qt.png This is my application. For this question, ignore the top part with the buttons. I have a QScrollArea Filled with many QGroupBoxes Filled with a horizontal box layout of QLabel (on the left) and QGroupBox (on the right) The right side is a vertical box layout of QPushButtons Every single element, the scrollarea, both boxes, the labels, and the buttons all have their style sheets modified so padding is 0px and margin is 0px. Why do i have all this extra space? The scroll area has space on all sides until its inner elements (the blue boxes) start. Then those boxes have space until its inner elements (the white boxes) start. Can someone tell me what is going on?

• SQL Server 2008 error message from stored procedure

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. When we met with such error message from stored procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in advance, George

• Programatically determining file "size on disk" in advance

  - by porkchop

  I need to know how big a given in-memory buffer will be as an on-disk (usb stick) file before I write it. I know that unless the size falls on the block size boundary, its likely to get rounded up, e.g. a 1 byte file takes up 4096 bytes on-disk. I'm currently doing this using GetDiskFreeSpace() to work out the disk block size, then using this to calculate the on-disk size like this: GetDiskFreeSpace(szDrive, &dwSectorsPerCluster, &dwBytesPerSector, NULL, NULL); dwBlockSize = dwSectorsPerCuster * dwBytesPerSector; if (dwInMemorySize % dwBlockSize != 0) { dwSizeOnDisk = ((dwInMemorySize / dwBlockSize) * dwBlockSize) + dwBlockSize; } else { dwSizeOnDisk = dwInMemorySize; } Which seems to work fine, BUT GetDiskFreeSpace() only works on disks up to 2GB according to MSDN. GetDiskFreeSpaceEx() doesn't return the same information, so my question is, how else can I calculate this information for drives 2GB? Is there an API call I've missed? Can I assume some hard values depending on the overall disk size?

• Offline database access

  - by dtech

  I have a small application which basically consists of an user-friendly CRUD interface to a few tables (and joined tables) It currently works with a MySQL database but I would like to make it available offline. My first thought was to create a SQLite "buffer" in between the MySQL database and the application, e.g. by executing all queries on the SQLite but also storing them in a log table so that they can be executed later in the main database with very basic conflict resolution (I will basically let the user solve it if a conflict is detected) Due to the simplicity of the application this shouldn't be too difficult and good exercise, but I think I would be re-inventing the wheel. So my question is: are there existing solutions or other approaches for this problem?

• Tools for understanding large codebase

  - by 0tar0gz

  Hi! My whole life I have been programming in simple plain text editor. Lately, I was contemplating about joining an open source project which is fairly large and written in C. I downloaded the sources, started to look around, read this, forget that... Then I thought to myself: this can't be true. This is 21st century there must be some tool which would help me to understand the code, perhaps some kind of IDE or "code navigator". What flows from here to where, this typedef struct is just interface to that private type, this function is just #define from above, function called in this file is defined in that file, ... you get the idea. Dear Stack Overflow, is this 21st century? Is there something like this?

• Is there a way to have a bit bucket pointer? (C/C++)

  - by Crazy Chenz

  Is there a way to have a bit bucket pointer? A lot of IO (specifically input related) system calls return data to a buffer of a specific size. Is there a trick or way to make a sorta bit bucket pointer, so I can accept any amount of data that will be thrown away. Doing something like "char tmp[INT_MAX]" is crazy. The behavior I am looking for is something like /dev/null, only in a pointer world. Not to hopeful on this.... just curious. Thanks, Chenz UPDATE: Perhaps mmap-ing /dev/null. Forgot about that when I asked the question.

• Same question to multiple remote users with different login

  - by user562802

  Hello all, This is my first post to Stack Overflow so apologies if I chosen wrong words for the title. I am very new to Google App Engine and python. I am building a web application using Pyhton and Django which is question and multiple answers type. Once the users are login to website,they will be provided with random questions from datastore. What my requirement is if certain users want to form group so that they all can get the same set of random questions to answer,is this possible ? Without forming the group each user are getting different random questions on their end. Thanks, Sunil

• Is there a way to optimise finding text items on a page (not regex)

  - by Jeepstone

  After seeing several threads rubbishing the regexp method of finding a term to match within an HTML document, I've used the Simple HTML DOM PHP parser (http://simplehtmldom.sourceforge.net/) to get the bits of text I'm after, but I want to know if my code is optimal. It feels like I'm looping too many times. Is there a way to optimise the following loop? //Get the HTML and look at the text nodes $html = str_get_html($buffer); //First we match the <body> tag as we don't want to change the <head> items foreach($html->find('body') as $body) { //Then we get the text nodes, rather than any HTML foreach($body->find('text') as $text) { //Then we match each term foreach ($terms as $term) { //Match to the terms within the text nodes $text->outertext = str_replace($term, '<span class="highlight">'.$term.'</span>', $text->outertext); } } } For example, would it make a difference to determine check if I have any matches before I start the loop maybe?

• How do C++ header files work?

  - by PulpFiction

  Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

• Haskell: foldl' accumulator parameter

  - by Clinton

  I've been asking a few questions about strictness, but I think I've missed the mark before. Hopefully this is more precise. Lets say we have: n = 1000000 f z = foldl' (\(x1, x2) y -> (x1 + y, y - x2)) z [1..n] Without changing f, what should I set z = ... So that f z does not overflow the stack? (i.e. runs in constant space regardless of the size of n) Its okay if the answer requires GHC extensions. My first thought is to define: g (a1, a2) = (!a1, !a2) and then z = g (0, 0) But I don't think g is valid Haskell.

• MPI_Bsend and MPI_Isend. How do they work ?

  - by GBBL

  Hi, using buffered send and non blocking send I was wondering how and if they implement a new level of parallelism in my application eventually generating a thread. Imagine that a slave process generates a large amount of data and want to send it to the master. My idea was to start a buffered or non blocking send then immediately begin to compute the next result. Just when I would have to send the new data I wold check if I can reuse the buffer. This would introduce a new level of parallelism in my application between CPU and communication. Does anybody knows how this is done in MPI ? Does MPI generate a new thread to handle the Bsend or Isend ? Thanks.

• Buttons size not equal in IE and Firefox

  - by Anurag

  I have few buttons on my jsp page and I am using the style as : .buttonblue { background-color: #003366; border-color: #99CCFF; color: #FFFFFF; font-family: Verdana,Arial,Helvetica; font-size: 8pt; font-weight: bold; height: 20px; display:inline; line-height: 1.2; text-align: center; margin-top: 2px; } In Firefox the buttons are bit smaller than IE6. I can not define the size of buttons as the caption changes the button size changes accordingly. I tried with width:auto but no success. Also, with overflow:visible the buttons in IE becomes bit smaller. Please help.

• after dup2, stream still contains old contents?

  - by BobTurbo

  so if I do: dup2(0, backup); // backup stdin dup2(somefile, 0); // somefile has four lines of content fgets(...stdin); // consume one line fgets(....stdin); // consume two lines dup2(backup, 0); // switch stdin back to keyboard I am finding at this point.. stdin still contains the two lines I haven't consumed. Why is that? Because there is just one buffer no matter how many times you redirect? How do I get rid of the two lines left but still remember where I was in the somefile stream when I want to go back to it?

• Python Regular Expression TypeError

• Best way to access a sqlite database file in a web service.

  - by rogernorling

  First question from me on stack overflow. I have created a java web application containing a web service using netbeans (I hope a web application were the correct choice). I use the web application as is with no extra frameworks. This web service use a sqlite JDBC driver for accessing a sqlite database file. My problem is that the file path end up incorrect when I try to form the JDBC connection string. Also, the working directory is different when deploying and when running JUnit tests. I read somewhere about including the file as a resource, but examples of this were nowhere to be seen. In any case, what is the best way to open the sqlite database, both when the web service is deployed and when I test it "localy"? I don't know much about web services, I just need it to work, so please, help me with the technicalities.

• Can't get jQuery and IE to be friends

  Using jQuery and the Cycle plugin. Runs flawless in Safari, Chrome, Firefox, and the latest version of Opera. Won't run in older versions of Opera, and of course, IE. I know its running Java, because its picking up the rollovers. This is driving me batty. Hopefully its something simple. Here's the code... $(document).ready(function() { $("#slideshow").css("overflow", "hidden"); $("div#slides").cycle({ fx: 'scrollHorz', speed: 'slow', timeout: 0, prev: '#prev', next: '#next' }); Really appreciate the help guys.

• Best of both worlds: arrow keys for cursor movement or flipping through buffers.

  - by dreeves

  I really like this vim trick to use the left and right arrows to flip between buffers: "left/right arrows to switch buffers in normal mode map <right> :bn<cr> map <left> :bp<cr> (Put that in ~/.vimrc) But sometimes I'm munching on a sandwich or something when scrolling around a file and I really want the arrow keys to work normally. I think what would make most sense is for the arrow keys to have the above buffer-flipping functionality only if there are actually multiple buffers open. Is there a way to extend the above to accomplish that?

• Extract data from uint8 to double

  - by HADJ AMOR HASSEN

  I have a C function receiving a uint8 pointer with another parameter which is its size (number of bytes). I want to extract double data from this buffer. Here is my code: Write(uint8* data, uint8 size) /* data and size are given by a callback to my function)*/ { double d; for (i = 0; i < size; i++) { d = ((double*)&data)[i]; printf(" d = %d\n"); } } The problem is that I am not receiving what I am sending within an external hardware. I guess that my cast is wrong. I tried other methods but without any good result. I am still not able to get what I send.
