• protocol parsing in c

  - by nomad.alien

  I have been playing around with trying to implement some protocol decoders, but each time I run into a "simple" problem and I feel the way I am solving the problem is not optimal and there must be a better way to do things. I'm using C. Currently I'm using some canned data and reading it in as a file, but later on it would be via TCP or UDP. Here's the problem. I'm currently playing with a binary protocol at work. All fields are 8 bits long. The first field(8bits) is the packet type. So I read in the first 8 bits and using a switch/case I call a function to read in the rest of the packet as I then know the size/structure of it. BUT...some of these packets have nested packets inside them, so when I encounter that specific packet I then have to read another 8-16 bytes have another switch/case to see what the next packet type is and on and on. (Luckily the packets are only nested 2 or 3 deep). Only once I have the whole packet decoded can I handle it over to my state machine for processing. I guess this can be a more general question as well. How much data do you have to read at a time from the socket? As much as possible? As much as what is "similar" in the protocol headers? So even though this protocol is fairly basic, my code is a whole bunch of switch/case statements and I do a lot of reading from the file/socket which I feel is not optimal. My main aim is to make this decoder as fast as possible. To the more experienced people out there, is this the way to go or is there a better way which I just haven't figured out yet? Any elegant solution to this problem?

• JQuery UI drag and drop doesn't notice DOM changes happening during the dragging ?

  - by user315677

  Hi everybody, I have a html table in which each line (<tr>) represents a group of client computers. Each line can be expanded to show the clients belonging to the group. The <tr> containing the clients are always generated but hidden and showed when clicking the plus button at the beginning of each line. The clients themselves (they are <div>) can be dragged and dropped in another group as long as this group is already expanded. So far it works fine. What I am trying to achieve now is that the client can be dragged to a collapsed group and after a second or so hovering the group it will be expanded and the client can be dropped amongst the other clients of the group. I programmed the hover using the in and outevents of the droppable and it expands the group all right, but (and now it starts to be hard to explain with words ;) the behavior of the droppable (the client) is still as if the table line that appeared were not there : the in out and drop events of the droppable are fired on the old position of the elements, and the in out and drop events of the newly appeared <tr> are never fired. It looks as if JQuery memorizes the position, size etc. of the elements when the drag starts, and these values are not updated if there is a change in the DOM before the drop happens... Can someone confirm this behavior is normal, or can it be caused by another problem in my own code ? Any workaround ? (the question is quite bloated already so I don't include any code but I'll gladly upload it if required)

• C++ syntax issue

  - by Doug

  It's late and I can't figure out what is wrong with my syntax. I have asked other people and they can't find the syntax error either so I came here on a friend's advice. template <typename TT> bool PuzzleSolver<TT>::solve ( const Clock &pz ) { possibConfigs_.push( pz.getInitial() ); vector< Configuration<TT> > next_; //error is on next line map< Configuration<TT> ,Configuration<TT> >::iterator found; while ( !possibConfigs_.empty() && possibConfigs_.front() != pz.getGoal() ) { Configuration<TT> cfg = possibConfigs_.front(); possibConfigs_.pop(); next_ = pz.getNext( cfg ); for ( int i = 0; i < next_.size(); i++ ) { found = seenConfigs_.find( next_[i] ); if ( found != seenConfigs_.end() ) { possibConfigs_.push( next_[i] ); seenConfigs_.insert( make_pair( next_[i], cfg ) ); } } } } What is wrong? Thanks for any help.

• Prepare community images for google image search indexing

  - by Vittorio Vittori

  Hi, I'm trying to understand how can I do to let my site be reachable from google image search spiders. I like how last.fm solution, and I thought to use a technique like his staff do to let google find artists images on their pages. When I'm looking for an artist and I search it on google image search, as often as not I find an image from last.fm artists page, I make an example: If I search the band Pure Reason Revolution It brings me here, the artist's image page http://www.last.fm/music/Pure+Reason+Revolution/+images/4284073 Now if I take a look to the image file, i can see it's named: http://userserve-ak.last.fm/serve/500/4284073/Pure+Reason+Revolution+4.jpg so if I try to undertand how the service works I can try to say: http://userserve-ak.last.fm/serve/ the server who serve the images 500/ the selected size for the image 4284073/ the image id for database Pure+Reason+Revolution+4.jpg the image name I thought it's difficult to think the real filename for the image is Pure+Reason+Revolution+4.jpg for image overwrite problems when an user upload it, in fact if I digit: http://userserve-ak.last.fm/serve/500/4284073.jpg I probably find the real image location and filename With this tecnique the image is highly reachable from search engines and easily archived. My question is, does exist some guide or tutorial to approach on this kind of tecniques, or something similar?

• Saving animated GIFs using urllib.urlopen (image saved does not animate)

  - by wenbert

  I have Apache2 + Django + X-sendfile. My problem is that when I upload an animated GIF, it won't "animate" when I output through the browser. Here is my code to display the image located outside the public accessible directory. def raw(request,uuid): target = str(uuid).split('.')[:-1][0] image = Uploads.objects.get(uuid=target) path = image.path filepath = os.path.join(path,"%s.%s" % (image.uuid,image.ext)) response = HttpResponse(mimetype=mimetypes.guess_type(filepath)) response['Content-Disposition']='filename="%s"'\ %smart_str(image.filename) response["X-Sendfile"] = filepath response['Content-length'] = os.stat(filepath).st_size return response UPDATE It turns out that it works. My problem is when I try to upload an image via URL. It probably doesn't save the entire GIF? def handle_url_file(request): """ Open a file from a URL. Split the file to get the filename and extension. Generate a random uuid using rand1() Then save the file. Return the UUID when successful. """ try: file = urllib.urlopen(request.POST['url']) randname = rand1(settings.RANDOM_ID_LENGTH) newfilename = request.POST['url'].split('/')[-1] ext = str(newfilename.split('.')[-1]).lower() im = cStringIO.StringIO(file.read()) # constructs a StringIO holding the image img = Image.open(im) filehash = checkhash(im) image = Uploads.objects.get(filehash=filehash) uuid = image.uuid return "%s" % (uuid) except Uploads.DoesNotExist: img.save(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext)))) del img filesize = os.stat(os.path.join(settings.UPLOAD_DIRECTORY,(("%s.%s")%(randname,ext)))).st_size upload = Uploads( ip = request.META['REMOTE_ADDR'], filename = newfilename, uuid = randname, ext = ext, path = settings.UPLOAD_DIRECTORY, views = 1, bandwidth = filesize, source = request.POST['url'], size = filesize, filehash = filehash, ) upload.save() #return uuid return "%s" % (upload.uuid) except IOError, e: raise e Any ideas?

• Loading an FLV in Facebox with jQuery for IE7 and IE8

  - by Trip

  It goes almost without saying, this works perfectly in Chrome, Firefox, and Safari. IE (any version) being the problem. Objective: I am trying to load JWplayer which loads an FLV from S3 in a Facebox popup. jQuery(document).ready(function($) { $('a[rel*=facebox]').facebox() }) HTML (haml): %li#videoGirl = link_to 'What is HQchannel?', '#player', :rel => 'facebox' .grid_8.omega.alpha#player{:style => 'display: none;'} :javascript var so = new SWFObject('/flash/playerTrans.swf','mpl','640px','360px','0'); so.addParam('allowscriptaccess','always'); so.addParam('allowfullscreen','true'); so.addParam('wmode','transparent'); so.addVariable('file', 'http://hometownquarterlyvideos.s3.amazonaws.com/whatishqchannel.flv&autostart=true&controlbar=none&repeat=always&image=/flash/video_girl/whatishqchannel.jpg&icons=false&screencolor=none&backcolor=FFFFFF&screenalpha=0&overstretch'); so.addVariable('overstretch', 'true') so.write('player'); Problem: Despite the video being set to display: none;. It begins playing anyway. When clicking on the activation div, IE7 pops up a wrong sized blank div with a nav (params are set to not show nav and scrubber), and no buttons on the nav and srubber work. IE8 shows the right size but same behavior with nav and scrubber not working, and blank screen. My guess: I'm thinking that the problem is with the javascript not being called at the right times. It seems it's loading the facebox without the jwplayer. At least I assume. Hence the reason why the nav is there. I thinking that it did not read the javascript for that.

• c++ File input/output

  Hi: I am trying to read from a file using fgets and sscanf. In my file, I have characters on each line of the while which I wish to put into a vector. So far, I have the following: FILE *fp; fp = fopen(filename, "r"); if(!fp) { fprintf(stderr, "Unable to open file %s\n", filename); return 0; } // Read file int line_count = 0; char buffer[1024]; while(fgets(buffer, 1023, fp)) { // Increment line counter line_count++; char *bufferp = buffer; ... while(*bufferp != '\n') { char *tmp; if(sscanf(bufferp, "%c", tmp) != 1) { fprintf(stderr, "Syntax error reading axiom on " "line %d in file %s\n", line_count, filename); return 0; } axiom.push_back(tmp); printf("put %s in axiom vector\n", axiom[axiom.size()-1]); // increment buffer pointer bufferp++; } } my axiom vector is defined as vector<char *> axiom;. When I run my program, I get a seg fault. It happens when I do the sscanf. Any suggestions on what I'm doing wrong?

• How to handle images better in Android

  - by primal

  In the microblogging application I am developing I wish to show an user image beside each post in the timeline. The images are small in size(max 50*50 dip) and are not more than 10 in number. I've two approaches in my mind. 1) Allow user to chose an image from Gallery on signing up. Send the image to the server and on subsequent signups load the image from the server. I'm worried whether this approach is doing too much unnecessary work. 2) The same method is same as above in first step but this time the image is not send to the server but a key value associated with the image is sent to the server. On subsequent signups, after obtaining the key from the server the specific image is loaded from gallery. I am not sure whether the second approach is possible. Any corrections on this aspect would be much appreciated. Also, Is it possible to store an image in SharedPreferences? Any new approach to handle this problem better are welcome.

• mmap only needed pages of kernel buffer to user space

  - by axeoth

  See also this answer: http://stackoverflow.com/a/10770582/1284631 I need something similar, but without having to allocate a buffer: the buffer is large, in theory, but the user space program only needs to access some parts of it (it mocks some registers of a hardware). As I cannot allocate with vmalloc_user() such a large buffer (kernel 32 bit, in embedded environment, no swap...), I followed the same approach as in the quoted answer, trying to allocate only those pages that are really requested by the user space. So: I use a my_mmap() function for the device file (actually, is the .mmap field of a struct uio_info) to set up the fields of the vma, then, in the vm_area_struct's .fault field (also named my_fault()), I should return a page. except that: In the my_fault() method of vm_area_struct, I cannot obtain a page through: vmf->page=vmalloc_to_page(my_buf + (vmf->pgoff << PAGE_SHIFT)); since there is no allocated buffer: my_buf = vmalloc_user(MY_BUF_SIZE); fails with "allocation failed: out of vmalloc space - use vmalloc= to increase size." (and there is no room or swap to increase that vmalloc= parameter). So, I would need to get a page from the kernel and fill the vmf->page field. How to allocate a page (I assume that the offset of the page is known, as it is vm->pgoff). What base memory should I use instead of my_buf? PS: I also did set up the vma->flags |= VM_NORESERVE; (in the my_mmap()), but not sure if it helps. Is there any vmalloc_user_unreserved()-like function? (let's say, lazy allocation) Also, writing 1 to /proc/sys/vm/overcommit_memory and large values (eg 500) to /proc/sys/vm/overcommit_ratio before trying to my_buf=vmalloc_user(<large_size>) didn't work.

• Ruby On Rails with HTML5 offline apps - Firefox does not cache the application.manifest but Safari does

  - by hoitomt

  I'm working off of this Railscast tutorial: episode 247 I’m up to this point in the tutorial: added the rack-offline gem, added the application.manifest route, and added a reference to the manifest in the html tag. Right before it starts talking about problems with caching. Safari works as intended – When the server is running the page is served. From the server logs I can see that Safari is making a single request to the server every time for the items page. When I turn off the server the page displays as well, even after shutting down the browser and restarting. It appears to be pulling from the application.manifest (cache manifest). Firefox does not work as intended – When accessing the page for the first time, Firefox lets me know that the web page wants to store something locally, I allow. After clicking on allow, Firefox makes 5 requests to the server for the page (from the server log). The hash is different in every request. Is it is possible that the changing hash is triggering Firefox to keep trying to get the new manifest until it reaches some maximum (5 attempts)? Then, after the server is stopped, Firefox will not show the page at all. It looks like it isn’t caching the application.manifest. Firefox also gives you a way to see what sites are storing stuff locally by going to Tools/Options/Advanced/Network (Firefox/Preferences/Advanced/Network on Apple). I see localhost there but the size is 0 bytes. So for some reason, Firefox is not downloading my application.manifest along with the files

• Auditing front end performance on web application

  - by user1018494

  I am currently trying to performance tune the UI of a company web application. The application is only ever going to be accessed by staff, so the speed of the connection between the server and client will always be considerably more than if it was on the internet. I have been using performance auditing tools such as Y Slow! and Google Chrome's profiling tool to try and highlight areas that are worth targeting for investigation. However, these tools are written with the internet in mind. For example, the current suggestions from a Google Chrome audit of the application suggests is as follows: Network Utilization Combine external CSS (Red warning) Combine external JavaScript (Red warning) Enable gzip compression (Red warning) Leverage browser caching (Red warning) Leverage proxy caching (Amber warning) Minimise cookie size (Amber warning) Parallelize downloads across hostnames (Amber warning) Serve static content from a cookieless domain (Amber warning) Web Page Performance Remove unused CSS rules (Amber warning) Use normal CSS property names instead of vendor-prefixed ones (Amber warning) Are any of these bits of advice totally redundant given the connection speed and usage pattern? The users will be using the application frequently throughout the day, so it doesn't matter if the initial hit is large (when they first visit the page and build their cache) so long as a minimal amount of work is done on future page views. For example, is it worth the effort of combining all of our CSS and JavaScript files? It may speed up the initial page view, but how much of a difference will it really make on subsequent page views throughout the working day? I've tried searching for this but all I keep coming up with is the standard internet facing performance advice. Any advice on what to focus my performance tweaking efforts on in this scenario, or other auditing tool recommendations, would be much appreciated.

• DataGridView: Scroll bar does not refreshed

  - by David.Chu.ca

  I am working (fixing bugs) on a project which was written in VS 2005. There is one DataGridView control on a form. When it is first time loaded, the control's data grid is populated with rows of data from a collection manually or in codes. Actually, there is method PopulateDataGrid() do the job. There is also another control on the form. When control is changed, the data grid will be cleared first and then rows are repopulated again through PopulateDataGrid(). The problem is that when the grid is refreshed, the vertical scroll bar does not get reset correctly. I thought it should be. Since the scroll bar is not reset, when I tried to click on grid and move down, I got exception: the max value of scroll bar was exceeded. All the settings for grid control are default values. For example, the ScrollBars is Both. The following is the only related place to set row auto size property: poDataGridView.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders; I am not sure if there is any property I have to set in designer?

• Using Matlab to find maxima for data with a lot of noise

  - by jimbo

  I have noisy data set with three peaks in Matlab and want to do some image processing on it. The peaks are about 5-9 pixels wide at the base, in a 50 x 50 array. How do I locate the peaks? Matlab is very new to me. Here is what I have so far... For my original image, let's call it "array", I tried J = fspecial('gaussian',[5 5], 1.5); C = imfilter(array, J) peaks = imregionalmax(C); but there is still some noise along the baseline between the peaks so I end up getting a ton of local max that are really just noise values. (I tried playing with the size of the filter, but that didn't help.) I also tried peaks = imextendedmax(C,threshold); where the threshold was determined visually... which works but is definitely not a good way to do it since it's not that robust obviously. So, how do I locate these peaks in a robust way? Thanks.

• Web Hosting: Any web host that supports files more than 50,000 in number?

  - by Devner

  Hi all, For my PHP & mySQL based application, I am trying to buy website hosting from a host who does not have a limit on the number of files I carry in my hosting account. Almost all the websites have a common limit of 50,000 files (some websites call it 50,000 nodes). The rest(to the extent of my search) are not even close. I have gone through the various websites, Googled lot of information, have spoken with the customer service of the hosting companies and they said that they have a limit of 50,000 files and that's why they call it the LIMIT. Now I have my application, which is a kind of social networking website, where people can upload various files of varying file size. So say if 50,000 users were to join the website and upload 1 file each, the limit of 50,000 will be reached very easily and my 50,001 customer will start facing file upload problems (& so will my account). So I would like to know if there's any website hosting services that do NOT levy such restrictions. In summary, I need the following options: No maximum file limit (more than 50,000 files in account). No maximum file upload limit in server setting (10MB, 12MB, 15MB, 20MB, etc.). Ability to upload files of various types (zip, flv, jg, png, etc.). Ability to stream Audio and Video (live audio & video not necessary). Access to .htaccess Access to php.ini, my.cnf or my.ini (this would be a plus) Supports SSL. Provides dedicated hosting(& IP) as well. Monthly payments without contracts are a plus. If you know of any such website hosting services, please post a reply ( a link to the same will be appreciated ). Thank you.

In other cases it means using a //specified disabledTextColor, such as on JTextComponents. //For example, JLabel doesn't specify a disabled color that the //developer can set, yet it should have a disabled color to the //text when the label is disabled. This code allows for that. if (c instanceof JTextComponent) { JTextComponent txt = (JTextComponent)c; Color disabledColor = txt.getDisabledTextColor(); if (disabledColor == null || disabledColor instanceof UIResource) { return getColorForState(context, type); } } else if (c instanceof JLabel && (type == ColorType.FOREGROUND || type == ColorType.TEXT_FOREGROUND)){ return getColorForState(context, type); } But I could not figure out how to set a disabled color for a JLabel Thanks for your help!

• real time stock quotes, StreamReader performance optimization

  - by sean717

  I am working on a program that extracts real time quote for 900+ stocks from a website. I use HttpWebRequest to send HTTP request to the site and store the response to a stream and open a stream using the following code: HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream stream = response.GetResponseStream (); StreamReader reader = new StreamReader( stream ) the size of the received HTML is large (5000+ lines), so it takes a long time to parse it and extract the price. For 900 files, It takes about 6 mins for parsing and extracting. Which my boss isn't happy with, he told me he'd want the whole process to be done in TWO mins. I've identified the part of the program that takes most of time to finish is parsing and extracting. I've tried to optimize the code to make it faster, the following is what I have now after some optimization: // skip lines at the top for(int i=0;i<1500;++i) reader.ReadLine(); // read the line that contains the price string theLine = reader.ReadLine(); // ... extract the price from the line now it takes about 4 mins to process all the files, there is still a significant gap to what my boss's expecting. So I am wondering, is there other way that I can further speed up the parsing and extracting and have everything done within 2 mins?

• Can this auto-stretcing scenario be realized undex XHTML/CSS?

  - by Vilx-

  I want two horizontal areas in my webpage. The first one is the menu. It's on the top. Unfortunately I don't know its size, and it might change in response to user actions. Below the menu is the main area which should stretch at least as far as the bottom of the window (if there is little content) or beyond (if there is a lot of content. To illustrate with ASCII art: +----------------------------------------------------+ | This area resizes vertically depending on contents | +----------------------------------------------------+ | This area stretches to the bottom of the window, | | but can be even larger if necessary. Note: this | | should be a separate area because it will contain | | children with height:100% as well. | | | +----------------------------------------------------+ Can this be done? Can it be done with Javascript? Added: To put things in perspective and avoid confusion, think of it this way: the top menu is generated by myself, but the bottom area is an IFrame which I want to fill the rest of the page. This is what it eventually comes down to anyway in my case.

• Paragraph with normal opacity within greyed-out div

  - by dmr

  I am greying out a web page when a user doesn't have permission to access it. In order to do that, I am placing a div with background-color white and a lowered opacity on top of the web page. I want to write some words in that div with the words having a normal opacity. As of now, the greyed out background is showing correctly. However, I can't seem to get the words to be a regular opacity. The derived styles on Firebug show the opacity on the words as normal, but it clearly isn't. What am I doing wrong? The HTML: <div class="noPermission"> <p>I'm sorry. You do not have permission to access this page.</p> </div> The CSS: div.noPermission { background-color: white; filter:alpha(opacity=50); /* IE */ opacity: 0.5; /* Safari, Opera */ -moz-opacity:0.50; /* FireFox */ z-index: 20; height: 100%; width: 100%; background-repeat:no-repeat; background-position:center; position:absolute; top: 0px; left: 0px; } div.noPermission p{ color: black; margin: 300px auto auto 50px; text-align: left; font-weight: bold; font-size: 18px; display: block; width: 250px; }

• Controls in UIActionSheet are positioning wrong

  - by Dave

  I need to display a pop with a UISwitch and a Done button when user taps on a button and save the state of the switch when the done button in the pop up is tapped. So I use UIActionSheet to do this - sheet = [[UIActionSheet alloc] initWithTitle:@"Switch Setting" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Done", nil]; theSwitch = [[UISwitch alloc] init]; [sheet addSubview:theSwitch]; [sheet showInView:self.view]; - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.firstOtherButtonIndex) { theSwitch .on? NSLog(@"Switch is on") : NSLog(@"Switch if off"); } } All this works great. I have problem with positioning. Unfortunately, I don't have a screen shot at the moment to post here. But the switch appears at the very top on the same line with the Action Sheet title and then below that is the Done button. Please someone help me how to position the switch below the Title and increase the Action Sheet size so it looks neat. I need this asap. Thanks.
