  • Asking for input without stopping the script in python.

    - by ImTooStupidForThis
    I am (trying) to make a simple IRC client in python (as kind of a project while I learn the language). I have a loop that I use to receive and parse what the IRC server sends me, but if I use raw_input to input stuff, it stops the loop dead in its tracks until I input something (obviously). How can I input something without the loop stopping? Thanks in advance. (I don´t think I need to post the code, I just want to input something without the while 1 loop stopping.)

  • Pulling name value pair from a structured adsense code block contained in a txt file

    - by Scott B
    I have a txt file which contains a google adsense code block and I'm trying to pull in the file via file_get_contents to extract the values of the google_ad_client and google_ad_slot variables. In the examples below, I want to return to my calling function: $google_ad_client = 'pub-1234567890987654'; $google_ad_slot = '1234567890' The file may contain one of either of these two formats and I wont know which the user has chosen: Newer Ad Unit Style <script type="text/javascript"><!-- google_ad_client = "pub-1234567890987654"; google_ad_slot = "1234567890"; google_ad_width = 336; google_ad_height = 280; //--> </script> <script type="text/javascript" src="path-to-google-script"></script> Classic Style <script type="text/javascript"><!-- google_ad_client = "pub-1234567890987654"; /* 336x280, created 8/6/09 */ google_ad_slot = "1234567890"; google_ad_width = 336; google_ad_height = 280; google_ad_format="336x280_as"; google_ad_type="text_image"; google_color_border="FFFFFF"; google_color_bg="FFFFFF"; google_color_link="2200CC"; google_color_url="000000"; google_color_text="777777"; //--> </script>

  • Multi domain rails app. How to intelligently use MVC?

    - by denial
    Background: We have app a, b, and plan to add more apps into this same application. The apps are similar enough they could share many views, assets, and actions. Currently a,b live in a single rails app(2.3.10). c will be similar enough that it could also be in this rails app. The problem: As we continue to add more apps to this one app, there's going to be too much case logic that the app will soon become a nightmare to maintain. There will also be potential namespace issues. However, the apps are very similar in function and layout, it also makes sense to keep them in one app so that it's one app to maintain(since roughly 50% of site look/functionality will be shared). What we are trying to do is keep this as clean as possible so it's easy for multiple teams to work on and easy to maintain. Some things we've thought about/are trying: Engines. Make each app an engine. This would let us base routes on the domain. It also allows us to pull out controllers, models and views for the specific app. This solution does not seem ideal as we won't be reusing the apps any time soon. And explicitly stating the host in the routes doesn't seem right. Skinning/themes. The auth logic would be different between the apps. Each user model would be different. So it's not just a skinning problem. In app/view add folder sitea for sitea views, siteb for siteb views and so on. Do the same for controllers and models. This is still pretty messy and since it didn't follow naming conventions, it did not work with rails so nicely and made much of the code messier. Making another rails app. We just didn't want to maintain the same controller or view in 2 apps if they are identical. What we want to do is make the app intelligently use a controller based on the host. So there would be a sessions controller for each app, and perhaps some parent session controller for shared logic(not needed now). In each of these session controllers, it handles authentication for that specific app. So if the domain is a.mysite.com, it would use session controller for app a and know to use app a's views,models,controllers. And if the domain is b.mysite, it would use the session controller for b. And there would be a user model for a and user model for b, which also would be determined by the domain. Does anyone have any suggestions or experience with this situation? And ideally using rails 2.3.x as updating to rails 3 isn't an option right now.

  • Please explain syntax rules and scope for "typedef"

    - by unknown google user
    What are the rules? OTOH the simple case seems to imply the new type is the last thing on a line. Like here Uchar is the new type. typedef unsigned char Uchar; But a function pointer is completely different. Here the new type is pFunc: typedef int (*pFunc) (int); I can't think of any other examples offhand but I have come across some very confusing usages. So are there rules or are people just suppose to know from experience that this is how it is done because they have seen it done this way before? ALSO: What is the scope of a typedef. Thanks to everyone.

  • How can I (from a script) add something to the zsh command history?

    - by Brandon
    I'd like to be able to look through my command history and know the context from which I issued various commands--in other words, "what directory was I in?" There are various ways I could achieve this, but all of them (that I can think of) would require manipulating the zsh history to add (for instance) a commented line with the result of $(pwd). (I could create functions named cd & pushd & popd etc, or I could use zsh's preexec() function and maybe its periodic() function to add the comment line at most every X seconds, just before I issue a command, or perhaps there's some other way.) The problem is, I don't want to directly manipulate the history file and bypass the shell's history mechanism, but I can't figure out a way (with the fc command, for instance) to add something to the history without actually typing it on the command line. How could I do this?

  • C/PHP: How do I convert the following PHP JSON API script into a C plugin for apache?

    - by TeddyB
    I have a JSON API that I need to provide super fast access to my data through. The JSON API makes a simply query against the database based on the GET parameters provided. I've already optimized my database, so please don't recommend that as an answer. I'm using PHP-APC, which helps PHP by saving the bytecode, BUT - for a JSON API that is being called literally dozens of times per second (as indicated by my logs), I need to reduce the massive RAM consumption PHP is consuming ... as well as rewrite my JSON API in a language that execute much faster than PHP. My code is below. As you can see, is fairly straight forward. <?php define(ALLOWED_HTTP_REFERER, 'example.com'); if ( stristr($_SERVER['HTTP_REFERER'], ALLOWED_HTTP_REFERER) ) { try { $conn_str = DB . ':host=' . DB_HOST . ';dbname=' . DB_NAME; $dbh = new PDO($conn_str, DB_USERNAME, DB_PASSWORD); $params = array(); $sql = 'SELECT homes.home_id, address, city, state, zip FROM homes WHERE homes.display_status = true AND homes.geolat BETWEEN :geolatLowBound AND :geolatHighBound AND homes.geolng BETWEEN :geolngLowBound AND :geolngHighBound'; $params[':geolatLowBound'] = $_GET['geolatLowBound']; $params[':geolatHighBound'] = $_GET['geolatHighBound']; $params[':geolngLowBound'] =$_GET['geolngLowBound']; $params[':geolngHighBound'] = $_GET['geolngHighBound']; if ( isset($_GET['min_price']) && isset($_GET['max_price']) ) { $sql = $sql . ' AND homes.price BETWEEN :min_price AND :max_price '; $params[':min_price'] = $_GET['min_price']; $params[':max_price'] = $_GET['max_price']; } if ( isset($_GET['min_beds']) && isset($_GET['max_beds']) ) { $sql = $sql . ' AND homes.num_of_beds BETWEEN :min_beds AND :max_beds '; $params['min_beds'] = $_GET['min_beds']; $params['max_beds'] = $_GET['max_beds']; } if ( isset($_GET['min_sqft']) && isset($_GET['max_sqft']) ) { $sql = $sql . ' AND homes.sqft BETWEEN :min_sqft AND :max_sqft '; $params['min_sqft'] = $_GET['min_sqft']; $params['max_sqft'] = $_GET['max_sqft']; } $stmt = $dbh->prepare($sql); $stmt->execute($params); $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC); /* output a JSON representation of the home listing data retrieved */ ob_start("ob_gzhandler"); // compress the output header('Content-type: text/javascript'); print "{'homes' : "; array_walk_recursive($result_set, "cleanOutputFromXSS"); print json_encode( $result_set ); print '}'; $dbh = null; } catch (PDOException $e) { die('Unable to retreive home listing information'); } } function cleanOutputFromXSS(&$value) { $value = htmlspecialchars($value, ENT_QUOTES, 'UTF-8'); } ?> How would I begin converting this PHP code over to C, since C is both better on memory management (since you do it yourself) and much, much faster to execute?

  • Is there a script that would allow me to edit multiple files as if they are one file in VIM?

    - by somewire
    I prefer to edit in one large file rather than many independent files, but due to limitations in languages, source control, and the preference of team mates I need to output to many files. What I'm looking for would recurse through all the files in a source directory and generate a single file to edit in VIM, with special file seperator markers. On save it would save the the changes to the correct file(s) ideally in a smart manner, based only on changes made. Does something like this exist?

  • Bash Script (Cygwin) to grep a logfile for multiple phrases and output a new file for each phrase.

    - by Chris
    Each logfile is titled based on the date it was created in the format YYYY-MM-DD.txt. I need to search each file for five different keywords and output five files prepended with the specific keyword and then the original logfile name. Example: Test-YYYY-MM-DD.txt grep -i -w 'keyword1' YYYY-MM-DD.txt Keyword1-YYYY-MM-DD.txt If it's also possible to email each new file to a different person, that would be helpful as well.

  • Best (or appropriate) WSGI server for this Python script? - Python

    - by RadiantHex
    Hi folks, I'm having quite a problem deciding how to serve a few Python scripts. The problem is that the basic functionality could be generalized by this: do_something() time.sleep(3) do_something() I tried various WSGI servers, but they have all been giving me concurrency limitations, as in I have to specify how many threads to use and so on. I only wish that the resources on the server be used efficiently and liberally. Any ideas?

  • jquery mobile - loading content into a div

    - by Robbiegod
    Jquery Mobile works by “hijacking” a page and loading content and injecting it into the page. It seems that this creates a problem when i try to inject other content into the page. I have my index.html and then a page2.html file. I'm setting up jquery mobile in the normal fashion wrapping the contents of each page in a div like so: <div id="container" data-role="page"> // my content <a href="page2.html">go to page 2</a> </div> when the user taps go to page 2, it does the nice slide effect. The url in the location bar looks like this: index.html#page2.html jquery mobile inject the content of the page using the anchors and applies the transition. nice so everthing works great up to the next part. On page2.html, i have a section that is loading some external data and injecting it into a div. <a href="http://www.somedomain.com/myata.php" class="ajaxtrigger" data-role="none">mydata</a> <div id="target"></div> <script src="js/code.js"></script> <script src="js/loader.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('.ajaxtrigger').trigger('click'); }); </script> The problem i am having is that when i enable the transitions in jquery mobile this script doesn't work. It won't load the data into the div. bummer. Anyone know what i need to do to get it to trigger and load the content into that div?

  • sqlite use in tcl script over nfs (or.. how to make standalone sqlite3 which can be run over nfs)

    - by wom
    Hello. I want to use an embed an sqlite database into an existing tcl application (Migrate from flat-file). Currently; our tcl interpreter is run from a network location; /bin/tclsh8.3 I do have an nfs $PATH for executables set for all users already; I am assuming I can place a standalone sqlite3 executible there; though I have been not found an easy way to compile a local lib independent sqlite yet... (all linux clients, running anything from red hat 9 to ubuntu 10.04) Anyone able to poke me in the right direction in building an sqlite3 standalone binary I can use in my nfs tcl install? Thanks, Chris

  • Why does my Perl TCP server script hang with many TCP connections?

    - by viraptor
    I've got a strange issue with a server accepting TCP connections. Even though there are normally some processes waiting, at some volume of connections it hangs. Long version: The server is written in Perl and binds a $srv socket with the reuse flag and listen == 5. Afterwards, it forks into 10 processes with a loop of $clt=$srv->accept(); do_processing($clt); $clt->shutdown(2); The client written in C is also very simple - it sends some lines, then receives all lines available and does a shutdown(sockfd, 2); There's nothing async going on and at the end both send and receive queues are empty (as reported by netstat). Connections last only ~20ms. All clients behave the same way, are the same implementation, etc. Now let's say I'm accepting X connections from client 1 and another X from client 2. Processes still report that they're idle all the time. If I add another X connections from client 3, suddenly the server processes start hanging just after accepting. The first blocking thing they do after accept(); is while (<$clt>) ... - but they don't get any data (on the first try already). Suddenly all 10 processes are in this state and do not stop waiting. On strace, the server processes seem to hang on read(), which makes sense. There are loads of connections in TIME_WAIT state belonging to that server (~100 when the problem starts to manifest), but this might be a red herring. What could be happening here?
