  • Python Socket Getting Connection Reset

    - by Ian
    I created a threaded socket listener that stores newly accepted connections in a queue. The socket threads then read from the queue and respond. For some reason, when doing benchmarking with 'ab' (apache benchmark) using a concurrency of 2 or more, I always get a connection reset before it's able to complete the benchmark (this is taking place locally, so there's no external connection issue). class server: _ip = '' _port = 8888 def __init__(self, ip=None, port=None): if ip is not None: self._ip = ip if port is not None: self._port = port self.server_listener(self._ip, self._port) def now(self): return time.ctime(time.time()) def http_responder(self, conn, addr): httpobj = http_builder() httpobj.header('HTTP/1.1 200 OK') httpobj.header('Content-Type: text/html; charset=UTF-8') httpobj.header('Connection: close') httpobj.body("Everything looks good") data = httpobj.generate() sent = conn.sendall(data) def http_thread(self, id): self.log("THREAD %d: Starting Up..." % id) while True: conn, addr = self.q.get() ip, port = addr self.log("THREAD %d: responding to request: %s:%s - %s" % (id, ip, port, self.now())) self.http_responder(conn, addr) self.q.task_done() conn.close() def server_listener(self, host, port): self.q = Queue.Queue(0) sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.bind( (host, port) ) sock.listen(5) for i in xrange(4): #thread count thread.start_new(self.http_thread, (i+1, )) while True: self.q.put(sock.accept()) sock.close() server('', 9999) When running the benchmark, I get totally random numbers of good requests before it errors out, usually between 4 and 500. Edit: Took me a while to figure it out, but the problem was in sock.listen(5). Because I was using apache benchmark with a higher concurrency (5 and up) it was causing the backlog of connections to pile up, at which point the connections started getting dropped by the socket.

  • scaling svg paths in Raphael 2.1

    - by user1229001
    I'm using SVG paths from a wikimedia commons map of the US. I've singled out Pennsylvania with its counties. I'm feeding the paths out of a database and using Raphael 2.1 to put them on the page. Because in the original map, Pennsylvania was so small and set at an angle, I'd like to scale up the paths and rotate Pa. so that it isn't on an angle. When I try to use Raphael's transform method, all the counties look strange and overlapped. I gave up on setting the viewBox when I heard that it doesn't work in all browsers. Anyone have any ideas? Here is my code: $(document).ready(function() { var $paths = []; //array of paths var $thisPath; //variable to hold whichever path we're drawing $.post('getmapdata.php', function(data){ var objData = jQuery.parseJSON(data); for (var i=0; i<objData.length; i++) { $paths.push(objData[i].path); //$counties.push(objData[i].name); }//end for drawMap($paths); }) function drawMap(data) { // var map = new Raphael(document.getElementById('map_div_id'),0, 0); var map = new Raphael(0, 0, 520, 320); //map.setViewBox(0,0,500,309, true); for (var i = 0; i < data.length; i++) { var thisPath = map.path(data[i]); thisPath.transform(s2); thisPath.attr({stroke:"#FFFFFF", fill:"#CBCBCB","stroke-width":"0.5"}); } //end cycling through i }//end drawMap });//end program

  • Need to format character precedence in Strings.

    - by Christian
    I'm currently writing a Roman Numeral Converter for the fun of it. The problem works up to the aforementioned character precedence. Since Roman Numerals are not positional, i.e. III does not symbolize 1*whatever base^2 + 1*whatever base^1 + 1*whatever base^0. That of course makes it hard when somebody types in XIV and I need to make sure that the I is not added in this case, but rather subtracted. I'm not sure how to do this. What would be the best approach to tackle this? I have both the Roman Symbols and their respective decimal numbers stored in arrays: const char cRomanArray[] = "IVXLCDM"; const int romanArray[] = { 1, 5, 10, 50, 100, 500, 1000 }; so it wouldn't be too hard for me to brute-force the damn thing by simply checking the precedence within the array, i.e. if the symbol is smaller than the next symbol, i.e. in the exampe 'XIV' if 'I' is smaller than 'V', in which case it would be because I have ordered them in the array, then I could make it subtract the value instead of add. But this seems like a very ugly solution. Are there perhaps any better ones? I was thinking something along the lines of Regular Expressions maybe( forgive me if that sounds like a horrible idea, I haven't used RegExp yet, but it sounds like it could do what I need, and that's to determine the characters in a string.)

  • Is using SharePoint as a intranet/extranet portal a good idea?

    - by Rob
    I work for a fortune 500 company in IT and we have developed many systems/applications to do a variety of things. We are in need of some commonality of these applications and a better portal/dashboard/landing page for these applications. So, our customers and employees would log into this portal and see all the "things" that they can do which then link to their own application. This could maybe just iframe in each application inside of this portal to keep brand and navigation consistency. We are trying to decide whether to use SharePoint 2007 or 2010 for this or develop a portal/dashboard of sorts in house. We would like this portal to look and feel very branded to our needs and really not even feel like its using SharePoint (if needed). An example is to provide our own Menu control that drives the navigation if needed. Does anyone have any pros/cons for using SharePoint in such a way? Any advice on implementation (e.g. use 2010, much easier to customize design than 2007, etc)?

  • Access Expression problem: it's too complex, so how do I turn it in to a function?

    - by Mike
    Access 2007 is telling me that my new expression is to complex. It used to work when we had 10 service levels, but now we have 19! Great! I've asked this question in SuperUser and someone suggested I try it over here. Suggestions are I turn it in to a function - but I'm not sure where to begin and what the function would look like. My expression is checking the COST of our services in the [PriceCharged] field and then assigning the appropriate HOURS [Servicelevel] when I perform a calculation to work out how much REVENUE each colleague has made when working for a client. The [EstimatedTime] field stores the actual hours each colleague has worked. [EstimatedTime]/[ServiceLevel]*[PriceCharged] Below is the breakdown of my COST to HOURS expression. I've put them on different lines to make it easier to read - please do not be put off by the length of this post, it's all the same info in the end. Many thanks,Mike ServiceLevel: IIf([pricecharged]=100(COST),6(HOURS), IIf([pricecharged]=200 Or [pricecharged]=210,12.5, IIf([pricecharged]=300,19, IIf([pricecharged]=400 Or [pricecharged]=410,25, IIf([pricecharged]=500,31, IIf([pricecharged]=600,37.5, IIf([pricecharged]=700,43, IIf([pricecharged]=800 Or [pricecharged]=810,50, IIf([pricecharged]=900,56, IIf([pricecharged]=1000,62.5, IIf([pricecharged]=1100,69, IIf([pricecharged]=1200 Or [pricecharged]=1210,75, IIf([pricecharged]=1300 Or [pricecharged]=1310,100, IIf([pricecharged]=1400,125, IIf([pricecharged]=1500,150, IIf([pricecharged]=1600,175, IIf([pricecharged]=1700,200, IIf([pricecharged]=1800,225, IIf([pricecharged]=1900,250,0)))))))))))))))))))

  • Emulate domready event with a custom event (mootools)

    - by Rob
    I need to fire a one time only custom event that functions like the domready event, in that if new events are added after the event has occurred they are fired immediately. This is for some code that cannot execute until certain data and resources are initialized, so I want to do something like this: // I am including a script (loadResources.js) to load data and other resources, // when loadResources.js is done doing it's thing it will fire resourcesAreLoaded with: window.fireEvent('resourcesAreLoaded'); window.addEvent('resourcesAreLoaded', function() { // this is fine }); $('mybutton').addEvent('click', function() { window.addEvent('resourcesAreLoaded', function() { // this is not fine, because resourcesAreLoaded has already fired // by the time the button is clicked }); }); If possible I would like resourcesAreLoaded to function like domready, and execute the code immediately if the event has already fired: window.addEvent('testIsReady', function() { alert('firing test'); }); window.fireEvent('testIsReady'); window.addEvent('test', function() { // this will never execute unless I call fireEvent('testIsReady') again alert('test 2'); }); window.addEvent('domready', function() { alert('domready is firing'); }); window.addEvent('domready', function() { setTimeout(function() { alert('domready has already fired, so this is executed immediately'); }, 500); });

  • Using custom coordinates with QGraphicsScene

    - by Rob
    I am experimenting with a WYSIWYG editor that allows a user to draw shapes on a page and the Qt graphics scene support seems perfect for this. However, instead of working in pixels I want all my QGraphicsItem objects to work in tenths of a millimetre but I don't know how to achieve this. For example: // Create a scene that is the size if an A4 page (2100 = 21cm, 2970 = 29.7cm) QGraphicsScene* scene = new QGraphicsScene(0, 0, 2100, 2970); // Add a rectangle located 1cm across, 1cm down, 5cm wide and 2cm high QGraphicsItem* item = scene->addRect(100, 100, 500, 200); ... QGraphicsView* view = new QGraphicsView(scene); setCentralWidget(view); Now, when I display the scene above I want the shapes to appear at correct size for the screen DPI. Is this simply a case of using QGraphicsView::scale or do I have to do something more complicated? Note that if I was using a custom QWidget instead then I would use QPainter::setWindow and QPainter::setViewport to create a custom mapping mode but I can't see how to do this using the graphics scene support.

  • Encoding h.264 with libavcodec/x264

    - by Leviathan
    I am attempting to encode video using libavcodec/libavformat. I'm trying to change the standard output-example.c from ffmpeg source. The AVI file is created on the disk, but the only sound is encoded. I tried adding a lot of options for x264 from here. All the other codecs works fine, mpeg2, mpeg4, mjpeg, xvid. In addition to specifying the parameters x264, I also set the codec to AVOutputFormat structure. That's all I've done. AVOutputFormat *pOutFormat; // in header file av_register_all(); AVCodec *codec = avcodec_find_encoder_by_name("libx264"); pOutFormat = guess_format("avi", NULL, NULL); pOutFormat->video_codec = codec->id; The debug output of my application: Output #0, mp4, to 'D:\1.avi': Stream #0.0: Video: libx264, yuv420p, 320x240, q=10-51, 500 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: aac, 44100 Hz, 1 channels, s16, 128 kb/s [libx264 @ 0x694010]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x694010]bitrate tolerance too small, using .01 [libx264 @ 0x694010]profile Main, level 2.0 [libx264 @ 0x694010]frame I:150 Avg QP:14.76 size: 2534 [libx264 @ 0x694010]mb I I16..4: 75.9% 0.0% 24.1% [libx264 @ 0x694010]final ratefactor: 17.57 [libx264 @ 0x694010]coded y,uvDC,uvAC intra: 42.7% 92.4% 47.4% [libx264 @ 0x694010]i16 v,h,dc,p: 11% 14% 2% 73% [libx264 @ 0x694010]i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 21% 18% 29% 5% 8% 10% 3% 3% 2% [libx264 @ 0x694010]kb/s:506.79

  • Changing the admin edit window display values

    - by Henri
    I have a database table with e.g. a weight value e.g. CREATE TABLE product ( id SERIAL NOT NULL, product_name item_name NOT NULL, . . weight NUMERIC(7,3), -- the weight in kg . . CONSTRAINT PK_product PRIMARY KEY (id) ); This results is the model: class Product(models.Model): . weight = models.DecimalField(max_digits=7, decimal_places=3, blank=True, null=True) . I store the weight in kg's, i.e. 1 kg is stores as 1, 0.1 kg or 100g is stored as 0.1 To make it easier for the user, I display the weight in the Admin list display in grams by specifying: def show_weight(self): if self.weight: weight_in_g = self.weight * 1000 return '%0f' % weight_in_g So if a product weighs e.g. 0.5 kg and is stored in the database as such, the admin list display shows 500 Is there also a way to alter the number shown in the 'Change product' window. This window now shows the value extracted from the database, i.e. 0.5. This will confuse a user when I tell him with the help_text to enter the number in g, while seeing the number of kgs. Before saving the product I override save as follows: def save(self): if self.weight: self.weight = self.weight / 1000 This converts the number entered in grams to kgs.

  • Having trouble animating Line in D3.js using and array of objects as data

    - by user1731245
    I can't seem to get an animated transition between line graphs when I pass in a new set of data. I am using an array of objects as data like this: [{ clicks: 40 installs: 10 time: "1349474400000" },{ clicks: 61 installs: 3 time: "1349478000000" }]; I am using this code to setup my ranges / axis's var xRange = d3.time.scale().range([0, w]), yRange = d3.scale.linear().range([h , 0]), xAxis = d3.svg.axis().scale(xRange).tickSize(-h).ticks(6).tickSubdivide(false), yAxis = d3.svg.axis().scale(yRange).ticks(5).tickSize(-w).orient("left"); var clicksLine = d3.svg.line() .interpolate("cardinal") .x(function(d){return xRange(d.time)}) .y(function(d){return yRange(d.clicks)}); var clickPath; function drawGraphs(data) { clickPath = svg.append("g") .append("path") .data([data]) .attr("class", "clicks") .attr("d", clicksLine); } function updateGraphs(data) { svg.select('path.clicks') .data([data]) .attr("d", clicksLine) .transition() .duration(500) .ease("linear") } I have tried just about everything to be able to pass in new data and see an animation between graph's. Not sure what I am missing? does it have something to do with using an array of objects instead of just a flat array of numbers as data?

  • How can I run a BitchX when I don't have ssh or shell access?

    - by Christopher
    I just installed an IRC bot, B****X (Don't ask, I don't know - the real name is not censored). I did all of the configuration and chmod'ed the pl files to 755, but running it won't work. My host does not allow SSH/Shell (which is how the documentation says to runs he script), but just going to the URL usually works because of this. However, I get a 500 (Internal Server Error) error.

  • javascript table sorting/paging (client-side). How big is too big?

    - by Aheho
    I'm using a jQuery plugin called Tablesorter to do client-side sorting of a log table in one of my applications. I am also making use of the tablepager add-in. I really like the responsiveness that client-side sorting and paging brings to the party. I also like how you don't have to hit the web server or database repeatedly. However I can see that, in time, the log I'm displaying could grow quite large. I'm sure there comes a point where client-side paging and sorting is going to be impractical. What point will this technique begin to collapse under it's own weight? 500 records? 2000 records? 10,000 records? EDIT: In nutshell, what criteria would you use to determine if you are going to use client-side sorting/paging as opposed to server-side paging? Does the size of expected result set factor into your decision? Where is the tipping point?

  • what webserver / mod / technique should I use to serve everything from memory?

    - by reinier
    I've lots of lookuptables from which I'll generate my webresponse. I think IIS with Asp.net enables me to keep static lookuptables in memory which I can use to serve up my responses very fast. Are there however also non .net solutions which can do the same? I've looked at fastcgi, but I think this starts X processes, of which anyone can handle Y requests. But the processes are by definition shielded from eachother. I could configure fastcgi to use just 1 process, but does this have scalability implications? anything using PHP or any other interpreted language won't fly because it is also cgi or fastcgi bound right? I understand memcache could be an option, though this would require another (local) socket connection which I'd rather avoid since everything in memory would be much faster. The solution can work under WIndows or Unix... it doesn't matter too much. The only thing which matters is that there will be a lot of requests (100/sec now and growing to 500/sec in a year), and I want to reduce the amount of webservers needed to process it. The current solution is done using PHP and memcache (and the occasional hit to the SQL server backend). Although it is fast (for php anyway), Apache has real problems when the 50/sec is passed. I've put a bounty on this question since I've not seen enough responses to make a wise choice. At the moment I'm considering either Asp.net or fastcgi with C(++).

  • Eclipse (Aptana) Typing Lag

    - by Zack
    Hello SO, I've been using Aptana for some time now, and as of recent I've been dealing with files that are really, really big (500+ lines of code, which is huge for me, being a novice developer). Whenever I deal with smaller files, I get that weird sensation that I'm "in front of" what's typing, but now I'm quite sure of it--there is a significant lag between when I type something and when I see the text appear on screen. I don't have this issue with Dreamweaver CS3, so I know my computer has the capability to edit these files without this happening, but Eclipse still lags. I also don't see when something is being deleted if I hold down backspace, I see the first few characters get deleted, but then everything "hangs." Once I release the backspace key, the characters that would've been shown deleting instantly vanish all at once. The same thing happens with the forward delete key. I'm beginning to think this is an issue with Java, since I have the same feeling that everything is slightly "behind me" when I'm using -any- Java application. The computer is an intel Pentium 4 3.2 GHz Prescott, with 2GB's of DDR400 RAM and a Radeon HD3650 graphics card. If anyone knows how to fix this lagging issue, I'm all ears (eyes?); if anyone can recommend a different IDE with capabilities similar to Aptana (I do Python, HTML, CSS and JS; I use Git for SCM), I'd be glad to give it a try. Thanks!

  • Timer a usage in msp430 in high compiler optimization mode

    Hi, I have used timer A in MSP430 with high compiler optimization, but found that my timer code is failing when high compiler optimization used. When none optimization is used code works fine. This code is used to achieve 1 ms timer tick. timeOutCNT is increamented in interrupt. Following is the code, //Disable interrupt and clear CCR0 TIMER_A_TACTL = TIMER_A_TASSEL | // set the clock source as SMCLK TIMER_A_ID | // set the divider to 8 TACLR | // clear the timer MC_1; // continuous mode TIMER_A_TACTL &= ~TIMER_A_TAIE; // timer interrupt disabled TIMER_A_TACTL &= 0; // timer interrupt flag disabled CCTL0 = CCIE; // CCR0 interrupt enabled CCR0 = 500; TIMER_A_TACTL &= TIMER_A_TAIE; //enable timer interrupt TIMER_A_TACTL &= TIMER_A_TAIFG; //enable timer interrupt TACTL = TIMER_A_TASSEL + MC_1 + ID_3; // SMCLK, upmode timeOutCNT = 0; //timeOutCNT is increased in timer interrupt while(timeOutCNT <= 1); //delay of 1 milisecond TIMER_A_TACTL = TIMER_A_TASSEL | // set the clock source as SMCLK TIMER_A_ID | // set the divider to 8 TACLR | // clear the timer MC_1; // continuous mode TIMER_A_TACTL &= ~TIMER_A_TAIE; // timer interrupt disabled TIMER_A_TACTL &= 0x00; // timer interrupt flag disabled Can anybody help me here to resolve this issue? Is there any other way we can use timer A so it works fine in optimization modes? Or do I have used is wrongly to achieve 1 ms interrupt? Thanks in advanced. Vishal N

  • What data structure to use / data persistence

    I have an app where I need one table of information with the following fields: field 1 - int or char field 2 - string (max 10 char) field 3 - string (max 20 char) field 4 - float I need the program to filter on field 1 based upon a segmented control and select a field 2 from a picker. From this data I need to look up field 4 to use in a calculation. Total records will be about 200. I never see it go above 400 - 500. I am going to use a singleton which I am able to do, I just need help with the structure for this with data persistence. What type of data structure should I use for this and should I use NSNumber, NSString, etc. or old data types like float, Char, etc. I thought about a struct put into an array but there is probably a better way. This is new to me so any help or reference to examples would be great. I also thought about a plist or dictionary but it looks like it is just a lookup and a field which obviously won't work. Core data looked like overkill to me. Also, with any recommendation how should I get initial data into it? I want the user to be able to edit and add to the database. Sorry for the old terms, you can see what generation I am from... Thanks in advance!!!!

  • django inner redirects

    - by Zayatzz
    Hello I have one project that in my own development computer (uses mod_wsgi to serve the project) caused no problems. In live server (uses mod_fastcgi) it generates 500 though. my url conf is like this: # -*- coding: utf-8 -*- from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^', include('jalka.game.urls')), ) and # -*- coding: utf-8 -*- from django.conf.urls.defaults import * from django.contrib.auth import views as auth_views urlpatterns = patterns('jalka.game.views', url(r'^$', view = 'front', name = 'front',), url(r'^ennusta/(?P<game_id>\d+)/$', view = 'ennusta', name = 'ennusta',), url(r'^login/$', auth_views.login, {'template_name': 'game/login.html'}, name='auth_login'), url(r'^logout/$', auth_views.logout, {'template_name': 'game/logout.html'}, name='auth_logout'), url(r'^arvuta/$', view = 'arvuta', name = 'arvuta',), ) and .htaccess is like that: Options +FollowSymLinks RewriteEngine on RewriteOptions MaxRedirects=10 # RewriteCond %{HTTP_HOST} .

  • How to stop ejabberd from using mnesia

    - by Eldad Mor
    I'm trying to establish a procedure for restoring my database from a crashed server to a new server. My server is running Ejabberd as an XMPP server, and I configured it to use postgresql instead of mnesia - or so I thought. My procedure goes something like "dump the contents of the original DB, run the new server, restore the contents of the DBs using psql, then run the system". However, when I try running Ejabberd again I get a crash: =CRASH REPORT==== 3-Dec-2010::22:05:00 === crasher: pid: <0.36.0> registered_name: [] exception exit: {bad_return,{{ejabberd_app,start,[normal,[]]}, {'EXIT',"Error reading Mnesia database"}}} in function application_master:init/4 Here I was thinking that my system is running on PostgreSQL, while it seems I was still using Mnesia. I have several questions: How can I make sure mnesia is not being used? How can I divert all the ejabberd activities to PGSQL? This is the modules part in my ejabberd.cfg file: {modules, [ {mod_adhoc, []}, {mod_announce, [{access, announce}]}, % requires mod_adhoc {mod_caps, []}, {mod_configure,[]}, % requires mod_adhoc {mod_ctlextra, []}, {mod_disco, []}, {mod_irc, []}, {mod_last_odbc, []}, {mod_muc, [ {access, muc}, {access_create, muc}, {access_persistent, muc}, {access_admin, muc_admin}, {max_users, 500} ]}, {mod_offline_odbc, []}, {mod_privacy_odbc, []}, {mod_private_odbc, []}, {mod_pubsub, [ % requires mod_caps {access_createnode, pubsub_createnode}, {plugins, ["default", "pep"]} ]}, {mod_register, [ {welcome_message, none}, {access, register} ]}, {mod_roster_odbc, []}, {mod_stats, []}, {mod_time, []}, {mod_vcard_odbc, []}, {mod_version, []} ]}. What am I missing? I am assuming the crash is due to the mnesia DB being used by Ejabberd, and since it's out of sync with the PGSQL DB, it cannot operate correctly - but maybe I'm totally off track here, and would love some direction. EDIT: One problem solved. Since I'm using amazon cloud, I needed to hardcode the ERLANG_NODE so it won't be defined by the hostname (which changes on reboot). This got my ejabberd running, but still I wish to stop using mnesia, and I wonder what part of ejabberd is still using it and how can I found it.

  • Can I output/flush data to screen while processing ajax page?

    - by Bee
    I need to display on my page a list of records pulled from a table. Ajax works fine (I query the database and put all the data inside a on the main page) but if I have lots of records (say 500+) it will hang until data is fully loaded, THEN it will be sent back to the page and correctly displayed. I would like to be able to display the records on the page while getting them, instead of being forced to wait until completion. I am trying with flush(); inside the remote (ajax) page but it still waits until full data is loaded. This is what I currently have inside the ajax page: At the very beginning: @apache_setenv('no-gzip', 1); @ini_set('zlib.output_compression', 0); @ini_set('implicit_flush', 1); for ($i = 0; $i < ob_get_level(); $i++) { ob_end_flush(); } ob_implicit_flush(1); Then whenever I have a echo call: ob_flush(); Now if I load the ajax page alone... it will list the records while reading them from the database. But if I call the same page via Ajax, it will hang and send all the data at once. Any idea? This is the function I use to get the ajax content ('id' is the target , 'url' refers to the ajax page that runs the database query to list the records): function ajax(id,url) { xmlhttp=new XMLHttpRequest(); xmlhttp.open("GET",url,false); xmlhttp.send(null); document.getElementById(id).innerHTML = parseScript(xmlhttp.responseText); }

  • My timer code is failing when IAR is configured to do max optimization

    - by Vishal
    Hi, I have used timer A in MSP430 with high compiler optimization, but found that my timer code is failing when high compiler optimization used. When none optimization is used code works fine. This code is used to achieve 1 ms timer tick. timeOutCNT is increamented in interrupt. Following is the code [Code] //Disable interrupt and clear CCR0 TIMER_A_TACTL = TIMER_A_TASSEL | // set the clock source as SMCLK TIMER_A_ID | // set the divider to 8 TACLR | // clear the timer MC_1; // continuous mode TIMER_A_TACTL &= ~TIMER_A_TAIE; // timer interrupt disabled TIMER_A_TACTL &= 0; // timer interrupt flag disabled CCTL0 = CCIE; // CCR0 interrupt enabled CCR0 = 500; TIMER_A_TACTL &= TIMER_A_TAIE; //enable timer interrupt TIMER_A_TACTL &= TIMER_A_TAIFG; //enable timer interrupt TACTL = TIMER_A_TASSEL + MC_1 + ID_3; // SMCLK, upmode timeOutCNT = 0; //timeOutCNT is increased in timer interrupt while(timeOutCNT <= 1); //delay of 1 milisecond TIMER_A_TACTL = TIMER_A_TASSEL | // set the clock source as SMCLK TIMER_A_ID | // set the divider to 8 TACLR | // clear the timer MC_1; // continuous mode TIMER_A_TACTL &= ~TIMER_A_TAIE; // timer interrupt disabled TIMER_A_TACTL &= 0x00; // timer interrupt flag disabled [/code] Can anybody help me here to resolve this issue? Is there any other way we can use timer A so it works fine in optimization modes? Or do I have used is wrongly to achieve 1 ms interrupt? Thanks in advanced. Vishal N

  • jQuery working in everything but IE7. (checked my commas)

    - by deadlyhifi
    The following code works in IE8, FF, Safari, Chrome etc. (not bothering with IE6 for this one), but doesn't work in IE7. I've been through the code with a fine tooth-comb. Checked the commas, messed around with ; but it's not going anywhere. I'm using the jQuery Validate and Uploadify scripts. Can anyone see the problem here? Thanks. <script type="text/javascript"> jQuery(document).ready(function($) { $("#validateform").validate({ errorClass: 'invalid', rules: { bike_url: { required: true, url: true } } }) $("#uploadify").uploadify({ 'uploader' : '<?php echo $url .

  • Rails: constraint violation on create but not on update

    - by justinbach
    Note: This is a "railsier" (and more succinct) version of this question, which was getting a little long. I'm getting Rails behavior on a production server that I can't replicate on the development server. The codebases are identical save for credentials and caching settings, and both are powered by Oracle 10g databases with identical schema (but different data). My Rails application contains a user model, which has_one registration; registration in turn has_and_belongs_to_many company_ownerships through a registration_ownerships table. Upon registering, users fill out data pertinent to all three models, including a series of checkboxes indicating what registration_ownerships might apply to their account. On the dev server, the registration process is seamless, no matter what data is entered. On production, however, if users check off any of the company ownership fields before submitting their registration, Oracle complains about a constraint violation on the primary key of the company_ownerships table (which is a two-field key based on company_ownership_id and registration_id) and users get the standard Rails 500 error screen. In every case, I've verified that no conflicting record on these two fields exists in the production database, so I don't know why the constraint is getting violated. To further confuse things, if a user registers without listing any ownerships and later goes back and modifies their account to reflect ownership data (which is done through the same interface), the application happily complies with their request and Oracle is well-behaved (this is both on production and dev). I've spent the past couple days trying to figure out what might be causing this problem and am reaching the end of my wits. Any advice would be greatly appreciated!

  • Conflict between two Javascripts (MailChimp validation etc. scripts & jQuery hSlides.js)

    - by Brian
    I have two scripts running on the same page, one is the jQuery.hSlides.js script http://www.jesuscarrera.info/demos/hslides/ and the other is a custom script that is used for MailChimp list signup integration. The hSlides panel can be seen in effect here: http://theatricalbellydance.com. I've turned off the MailChimp script because it was conflicting with the hSlides script, causing it not to to fail completely (as seen here http://theatricalbellydance.com/home2/).
