• Home ADSL Modem Dropping Packets?

  - by Cody

  I know this is supposed to be a "pro" forum, but I'm hoping someone can help since my ISP isn't doing much to try and fix things. My ISP has given me a DSL modem / Router combo - a ADB / Pirelli P.DG A2100N and I have a 4096 / 767 kbps connection. I use it purely as modem and router, and have the wireless AP feature turned off. I run it to a Ubiquiti Networks Toughswitch and use a Ubiquiti UAP as the wireless access point - although I've ran tests directly wired to the router with nothing else connected, and still see the same issues. I've been having issues where latency suddenly spikes from 8ms to google.com to 250+ if someone does anything on the internet. If I run a speedtest or something, I can see latencies above 3000ms. Regularly when downloading something, even if the speed is throttled to , it can get random drops to 0kbps every few seconds. Online gaming is impossible because I notice the sudden lag-outs in the connection, and video streams or VoIP drop out as well - it's not at all consistent. I managed to find the password to my modem and I don't think I see anything wrong with the settings - but I looked for the logs and found this: Jun 6 17:10:30 user warn kernel: nf_conntrack: table full, dropping packet. Jun 6 17:10:30 user warn kernel: nf_conntrack: table full, dropping packet. Jun 6 17:10:31 user warn kernel: nf_conntrack: table full, dropping packet.

If that's the case, is there anything in the config that I can change? Or should I buy a new router, a new modem, or both?

• Error 502 in OpenOfficeSpreadsheet formula

  - by cody

  The formula failing is the following: =IF(TIMEVALUE(C2 & ":00") > TIMEVALUE(B2 & ":00"); 0; C2-B2) I previously tried =IF(C2 > B2; 0; C2-B2) but this also gives me "Error 502". The cells it is referring to contains data in the format "12:30" (I formatted the columns with format "HH:MM"). I just want to calculate how much time lies between two times, respecting the special case where endtime < starttime.

• how to word wrap, align text like the output of man?

  - by cody

  what is the command that word wraps and justifies a text file so that the output looks like that of a man page: All of these system calls are used to wait for state changes in a child of the calling process, and obtain information about the child whose state has changed. A state change is considered to be: the child terminated; the child was stopped by a signal; or the child was resumed by a signal. In the case of a terminated child, performing a wait allows the system to release the resources associated with the child; if a wait is not performed, then the termi- nated child remains in a "zombie" state (see NOTES below). Thanks.

• Obtaining MFC Feature Pack GUI elements in .NET WinForms

  - by Cody Gray

  The MFC Feature Pack (and VS 2010) adds out-of-the-box support for several "modern" GUI elements (such as MDI with tabbed documents, the ribbon, and a Visual Studio-style interface with docking panels). These are a boon to those of us that have to support legacy MFC-based applications and want to update their look-and-feel, and a sign that Microsoft has not completely abandoned unmanaged C++ development. However, with the push so strongly in favor of .NET, WinForms, and managed code (and for plenty of good reasons), there seems little reason to develop new applications in unmanaged C++/MFC. The question then becomes how does one obtain these GUI elements in a WinForms application. Almost all of the add-ons and libraries I have found so far cost money, and introduce additional dependencies. I don't have a budget to buy third-party libraries, and the controls provided by Microsoft in MFC for free seem sufficient for our needs. But I still have reservations about learning MFC to develop a new application. Not only does the investment in time seem significant (by all accounts, MFC seems particularly difficult to learn, even for experienced .NET developers--although I am willing to try), but the question of MFC's lifespan is raised as well. Certainly, given the millions of lines of code and existing apps written in native C++, it will be around for some time, but the handwriting seems to be on the wall, so to speak, that it's no longer Microsoft's touted development platform. It seems like these features should be available by now in WinForms without the need for third-party add-ons, or devoting a lot of time and resources to custom-drawing EVERYTHING. Am I just missing something? I find very little online that compares these new features of MFC to what is available in WinForms, mainly because most everything written on MFC pre-dated its most recent update, before which it looked admitted "dated," and with its other flaws, was hardly an appealing platform for new development. With the very recent release of VS 2010, we have a while to wait before WinForms gets updated again. What routes are you guys taking for applications whose customers demand a modern-looking UI on a budget?

• RIA Services vs ADO.NET Data Services

  - by Cody C

  I'm currently in the process of creating a Silverlight 3 data driven application. To access the database, 2 common approaches are used: RIA Services and ADO.NET Data Services. Does anyone have any guidance on when/why to choose each approach? Here is what I've gathered from my research / experience. Any thoughts? ADO.NET seems to be only useful for strictly database calls. If you need to expose the data services to other applications (ignoring Silverlight 3's domain restriction), this is a good approach. Also, if the URL/Query syntax can be useful in your application, this is another advantage RIA Services seem to be a more flexible, accepted framework. It seems to give you more than strictly database access. It does have a limitation of only being used for the Silverlight / Web application as it is not exposed via a service. Thoughts? Ideas? Comments?

• How can I change the images on an ImageButton in Android when using a OnTouchListener?

  - by Cody

  I have the following code which creates an ImageButton and plays a sound when clicked: ImageButton SoundButton1 = (ImageButton)findViewById(R.id.sound1); SoundButton1.setImageResource(R.drawable.my_button); SoundButton1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN ) { mSoundManager.playSound(1); return true; } return false; } }); The problem is that I want the image on the ImageButton to change when you press it. The OnTouchListener appears to be overriding the touch and not allowing the images to change. As soon as I remove the OnTouchListener, the ImageButton swaps to a different image when pressed. Any ideas on how I can have the images change on the ImageButton while still using the OnTouchListener? Thank you very much!

• Initializing links in jqtouch in AJAX loaded content

  - by Cody Caughlan

  I have an iphone web app built in jqtouch, when content is loaded by links ("a" tags) then any content on the next page is parsed by jqtouch and any links are initialized. However, when I load content via an AJAX call and append() it to an element then any links in that content are NOT initialized by jqtouch. Thus any clicks on those links are full-blown clicks to a new resource and are not handled by jqtouch, so at that point you've effectively broken out of jqtouch. My AJAX code is: #data <script type="text/javascript"> $.ajax({ url: '/mobile/nearby-accounts', type: 'GET', dataType: 'html', data: {lat: lat, lng: lng}, success: function(html) { $('#data').empty().append(html); // Is there some method I call on jqtouch to have any links in $('#data') be hooked up to the jqtouch lifecycle? } </script> Thanks in advance.

• Switching to landscape mode in Android Emulator

  - by Cody

  This is probably a pretty easy to answer question, but I can't find the solution myself after a couple hours of searching the documentation and Google. I set the orientation of my Android app to landscape in the AndroidManifest.xml file: android:screenOrientation="landscape" However, when I run the app in the simulator, it appears sideways and in portrait mode. How can I switch the emulator to landscape mode on a mac? It's running the 1.6 SDK. Thanks!

• didSelectRowAtIndexPath TableView Popover Issue

  - by Jack Cody

  I've tried a lot of different code examples including just brute force try this try that but, stumped. The popover left arrow seems to display just fine if the first row is displayed at the very top of the table view but, when the table scrolls down the popover left arrow doesn't align correctly with the table row selected. Solutions or suggestions would be most appreciated. CGRect myFrame = [tableView rectForRowAtIndexPath:indexPath]; [self.editViewPopoverController setPopoverContentSize:CGSizeMake(320, 400)]; [self.editViewPopoverController presentPopoverFromRect:CGRectMake(myFrame.origin.x, myFrame.origin.y + offset, 400, 0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES]; Thanks.

• Finding the last focused element with jQuery.

  - by Joshua Cody

  I'm looking to determine which element had the last focus in a series of inputs, that are added dynamically by the user. This code can only get the inputs that are available on page load: $('input.item').focus(function(){ $(this).siblings('ul').slideDown(); }); And this code sees all elements that have ever had focus: $('input.item').live('focus', function(){ $(this).siblings('ul').slideDown(); }); The HTML structure is this: <ul> <li><input class="item" name="goals[]"> <ul> <li>long list here</li> <li>long list here</li> <li>long list here</li> </ul></li> </ul> <a href="#" id="add">Add another</a> On page load, a single input loads. Then with each add another, a new copy of the top unordered list's contents are made and appended. And when each gets focus, I'd like to show the list beneath it. But I don't seem to be able to "watch for the most recently focused element, which exists now or in the future." Do I have some sort of fundamental assumption wrong?

• Using a checkbox input on a form to send the form data to different email addresses

  - by Cody Thomas

  I am building a form for a client. Here is the rundown. The form will be used as a request to have a staff member contact the person filling out the form. However, there is a list of staff members that will contact them depending on what the subject matter is. So, I want to create a checkbox input section on the form with each staff person's email address attached to a corresponding checkbox. So, the person filling out the form can check only the staff people necessary for their needs. Finally, when the person clicks "submit", the form will be emailed to only the staff members who were checked in the form. I'm at a loss of how to set this up.

• XCode Intellisense Question

  - by Cody C

  I've always seem to work around this lack of knowledge but I thought I would ask the community. I hope this question will make sense. In XCode, when I call a function that has several parameter the intellisense pops up. When I hit TAB the first time, it takes me directly to the first parameter. How do I get to the next parameter easily. If I hit TAB again, it puts an actual TAB in the line. For the last month I've been using arrow keys but I figured there must be a keyboard shortcut.

• Scheme Infix to Postfix

  - by Cody

  Let me establish that this is part of a class assignment, so I'm definitely not looking for a complete code answer. Essentially we need to write a converter in Scheme that takes a list representing a mathematical equation in infix format and then output a list with the equation in postfix format. We've been provided with the algorithm to do so, simple enough. The issue is that there is a restriction against using any of the available imperative language features. I can't figure out how to do this in a purely functional manner. This is our fist introduction to functional programming in my program. I know I'm going to be using recursion to iterate over the list of items in the infix expression like such. (define (itp ifExpr) ( ; do some processing using cond statement (itp (cdr ifExpr)) )) I have all of the processing implemented (at least as best I can without knowing how to do the rest) but the algorithm I'm using to implement this requires that operators be pushed onto a stack and used later. My question is how do I implement a stack in this function that is available to all of the recursive calls as well?

• CSS semantics; selecting elements directly or via order

  - by Joshua Cody

  Perhaps this question has been asked elsewhere, but I'm unable to find it. With HTML5 and CSS3 modules inching closer, I'm getting interested in a discussion about the way we write CSS. Something like this where selection is done via element order and type is particularly fascinating. The big advantage to this method seems to be complete modularization of HTML and CSS to make tweaks and redesigns simpler. At the same time, semantic IDs and classes seem advantageous for sundry reasons. Particularly, direct linking, JS targeting, and shorter CSS selectors. Also, it seems selector length might be an issue. For instance, I just wrote the following, which would be admittedly easier using some semantic HTML5 elements: body>div:nth-child(2)>div:nth-child(2)>ul:nth-child(2)>li:last-child So what say you, Stack Overflow? Is the future of CSS writing focused on element order and type? Or are IDs and classes and the current ways here to stay? (I'm well aware the IDs and classes have their place, although I am interested to hear more ways you think they'll continue to be necessary. The discussion I'm interested in is bigger-picture and the ways writing CSS is changing.)

• WPF databinding update comboxbox2 based on selection change in combobox1 with MVVM

  - by cody

  I have a combo box that I have bound to a list that exists in my viewmodel. Now when a users makes a selection in that combo box I want a second combo box to update its content. So, for example, combobox1 is States and combobox2 should contain only the Zipcodes of that state. But in my case I don't have a predefined lists before hand for combobox2, I need to go fetch from a db. Also, if needed, I could get all the potential values for combobox2 (for each combobox1 value) before hand, but I'd like to avoiding that if I can. How do I implement in WPF and using MVVM? I'm fairly new to this whole wpf\databinding\mvvm world.

• Node.js vs PHP processing speed

  - by Cody Craven

  I've been looking into node.js recently and wanted to see a true comparison of processing speed for PHP vs Node.js. In most of the comparisons I had seen, Node trounced Apache/PHP set ups handily. However all of the tests were small 'hello worlds' that would not accurately reflect any webpage's markup. So I decided to create a basic HTML page with 10,000 hello world paragraph elements. In these tests Node with Cluster was beaten to a pulp by PHP on Nginx utilizing PHP-FPM. So I'm curious if I am misusing Node somehow or if Node is really just this bad at processing power. Note that my results were equivalent outputting "Hello world\n" with text/plain as the HTML, but I only included the HTML as it's closer to the use case I was investigating. My testing box: Core i7-2600 Intel CPU (has 8 threads with 4 cores) 8GB DDR3 RAM Fedora 16 64bit Node.js v0.6.13 Nginx v1.0.13 PHP v5.3.10 (with PHP-FPM) My test scripts: Node.js script var cluster = require('cluster'); var http = require('http'); var numCPUs = require('os').cpus().length; if (cluster.isMaster) { // Fork workers. for (var i = 0; i < numCPUs; i++) { cluster.fork(); } cluster.on('death', function (worker) { console.log('worker ' + worker.pid + ' died'); }); } else { // Worker processes have an HTTP server. http.Server(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'}); res.write('<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n'); for (var i = 0; i < 10000; i++) { res.write('<p>Hello world</p>\n'); } res.end('</body>\n</html>'); }).listen(80); } This script is adapted from Node.js' documentation at http://nodejs.org/docs/latest/api/cluster.html PHP script <?php echo "<html>\n<head>\n<title>Speed test</title>\n</head>\n<body>\n"; for ($i = 0; $i < 10000; $i++) { echo "<p>Hello world</p>\n"; } echo "</body>\n</html>"; My results Node.js $ ab -n 500 -c 20 http://speedtest.dev/ This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: Server Hostname: speedtest.dev Server Port: 80 Document Path: / Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 14.603 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95066500 bytes HTML transferred: 95035000 bytes Requests per second: 34.24 [#/sec] (mean) Time per request: 584.123 [ms] (mean) Time per request: 29.206 [ms] (mean, across all concurrent requests) Transfer rate: 6357.45 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 2 Processing: 94 547 405.4 424 2516 Waiting: 0 331 399.3 216 2284 Total: 95 547 405.4 424 2516 Percentage of the requests served within a certain time (ms) 50% 424 66% 607 75% 733 80% 813 90% 1084 95% 1325 98% 1843 99% 2062 100% 2516 (longest request) PHP/Nginx $ ab -n 500 -c 20 http://speedtest.dev/test.php This is ApacheBench, Version 2.3 <$Revision: 655654 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking speedtest.dev (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Completed 400 requests Completed 500 requests Finished 500 requests Server Software: nginx/1.0.13 Server Hostname: speedtest.dev Server Port: 80 Document Path: /test.php Document Length: 190070 bytes Concurrency Level: 20 Time taken for tests: 0.130 seconds Complete requests: 500 Failed requests: 0 Write errors: 0 Total transferred: 95109000 bytes HTML transferred: 95035000 bytes Requests per second: 3849.11 [#/sec] (mean) Time per request: 5.196 [ms] (mean) Time per request: 0.260 [ms] (mean, across all concurrent requests) Transfer rate: 715010.65 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 0.2 0 1 Processing: 3 5 0.7 5 7 Waiting: 1 4 0.7 4 7 Total: 3 5 0.7 5 7 Percentage of the requests served within a certain time (ms) 50% 5 66% 5 75% 5 80% 6 90% 6 95% 6 98% 6 99% 6 100% 7 (longest request) Additional details Again what I'm looking for is to find out if I'm doing something wrong with Node.js or if it is really just that slow compared to PHP on Nginx with FPM.

• Adding a JLabel to JLayeredPane from event listener not dragging.

  - by Cody

  Ok, So for some reason When I add components to a JLayeredPane in its constructor: JLabel label = new JLabel(); label.setSize(100,100); label.setText("This works"); add(label); It works perfectly fine, but If a add it later in the JLayeredPane's parent EDT it doesnt let me move the objects around but they let me see the objects. Adding from EDT: JLabel label = new JLabel(); label.setToolTipText(url.getHost()); label.setIcon(icon); label.setBorder(new LineBorder(null)); label.setSize(icon.getIconWidth(), icon.getIconHeight()); dressFrame.layeredPane.add(label, JLayeredPane.DRAG_LAYER); Dragging method: Component c = findComponentAt(e.getX(), e.getY()); if (c instanceof JLayeredPane) { pieceSelected = false; return; } Point parentLocation = c.getLocation(); xAdjustment = parentLocation.x - e.getX(); yAdjustment = parentLocation.y - e.getY(); movingPiece = c; movingPiece.setLocation(e.getX() + xAdjustment, e.getY() + yAdjustment); pieceSelected = true;

I'm looking to find the element that currently has focus, even if said element is not present upon original page load. So in the above image, if I were to focus on the second element, the list of words should appear under the second element. My focus is currently on the last element, so the words are displayed there. Do I have some sort of fundamental assumption wrong?

• ORDER BY giving wrong order

  - by Cody Dull

  I have an SQL statement in my C# program that looks like: SELECT * FROM XXX.dbo.XXX WHERE Source = 'OH' AND partnum = '1231202085' ORDER BY partnum, Packaging, Quantity When running this query in SQL Server Management, the results are ordered as expected. My first 3 results have the same partnum and Packaging with Quantities of 32.0, 50.8, and 51.0. However, when I run the query from my program, the result set with quantity 50.8 is the first to be returned. The datatype of Quantity is decimal(18,9). I've tried cast, it doesn't appear to be a datatype problem. I cant figure out why its getting the middle quantity.

• How can I turn a SimpleXML object to array, then shuffle?

  - by Joshua Cody

  Crux of my problem: I've got an XML file that returns 20 results. Within these results are all the elements I need to get. Now, I need to return them in a random order, and be able to specifically work with item 1, items 2-5, and items 6-17. Idea 1: Use this script to convert the object to an array, which I can shuffle through. This is close to working, but a few of the elements I need to get are under a different namespace, and I don't seem to be able to get them. Code: /* * Convert a SimpleXML object into an array (last resort). * * @access public * @param object $xml * @param boolean $root - Should we append the root node into the array * @return array */ function xmlToArray($xml, $root = true) { if (!$xml->children()) { return (string)$xml; } $array = array(); foreach ($xml->children() as $element => $node) { $totalElement = count($xml->{$element}); if (!isset($array[$element])) { $array[$element] = ""; } // Has attributes if ($attributes = $node->attributes()) { $data = array( 'attributes' => array(), 'value' => (count($node) > 0) ? xmlToArray($node, false) : (string)$node // 'value' => (string)$node (old code) ); foreach ($attributes as $attr => $value) { $data['attributes'][$attr] = (string)$value; } if ($totalElement > 1) { $array[$element][] = $data; } else { $array[$element] = $data; } // Just a value } else { if ($totalElement > 1) { $array[$element][] = xmlToArray($node, false); } else { $array[$element] = xmlToArray($node, false); } } } if ($root) { return array($xml->getName() => $array); } else { return $array; } } $thumbfeed = simplexml_load_file('http://gdata.youtube.com/feeds/api/videos?q=skadaddlemedia&max-results=20&orderby=published&prettyprint=true'); $xmlToArray = xmlToArray($thumbfeed); $thumbArray = $xmlToArray["feed"]; for($n = 0; $n < 18; $n++){ $title = $thumbArray["entry"][$n]["title"]["value"]; $desc = $thumbArray["entry"][0]["content"]["value"]; $videoUrl = $differentNamespace; $thumbUrl = $differentNamespace; } Idea 2: Continue using my working code that is getting the information using a foreach, but store each element in an array, then use shuffle on that. I'm not precisely sure hwo to write to an array within a foreach loop and not write over one another, though. Working code: foreach($thumbfeed->entry as $entry){ $thumbmedia = $entry->children('http://search.yahoo.com/mrss/') ->group ; $thumb = $thumbmedia->thumbnail[0]->attributes()->url; $thumburl = $thumbmedia->content[0]->attributes()->url; $thumburl1 = explode("http://www.youtube.com/v/", $thumburl[0]); $thumbid = explode("?f=videos&app=youtube_gdata", $thumburl1[1]); $thumbtitle = $thumbmedia->title; $thumbyt = $thumbmedia->children('http://gdata.youtube.com/schemas/2007') ->duration ; $thumblength = $thumbyt->attributes()->seconds; } Ideas on if either of these are good solutions to my problem, and if so, how I can get over my execution humps? Thanks so much for any help you can give.

  - by Cody N

  Over the last two days I've effectively figured out how NOT to rotate Raphael Elements. Basically I am trying to implement a multiple pivot points on element to rotate it by mouse. When a user enters rotation mode 5 pivots are created. One for each corner of the bounding box and one in the center of the box. When the mouse is down and moving it is simple enough to rotate around the pivot using Raphael elements.rotate(degrees, x, y) and calculating the degrees based on the mouse positions and atan2 to the pivot point. The problem arises after I've rotated the element, bbox, and the other pivots. There x,y position in the same only there viewport is different. In an SVG enabled browser I can create new pivot points based on matrixTransformation and getCTM. However after creating the first set of new pivots, every rotation after the pivots get further away from the transformed bbox due to rounding errors. The above is not even an option in IE since in is VML based and cannot account for transformation. Is the only effective way to implement element rotation is by using rotate absolute or rotating around the center of the bounding box? Is it possible at all the create multi pivot points for an object and update them after mouseup to remain in the corners and center of the transformed bbox?

• Storing multiple inputs with the same name in a CodeIgniter session

  - by Joshua Cody

  I've posted this in the CodeIgniter forum and exhausted the forum search engine as well, so apologies if cross-posting is frowned upon. Essentially, I've got a single input, set up as <input type="text" name="goal">. At a user's request, they may add another goal, which throws a duplicate to the DOM. What I need to do is grab these values in my CodeIgniter controller and store them in a session variable. My controller is currently constructed thusly: function goalsAdd(){ $meeting_title = $this->input->post('topic'); $meeting_hours = $this->input->post('hours'); $meeting_minutes = $this->input->post('minutes'); $meeting_goals = $this->input->post('goal'); $meeting_time = $meeting_hours . ":" . $meeting_minutes; $sessionData = array( 'totaltime' => $meeting_time, 'title' => $meeting_title, 'goals' => $meeting_goals ); $this->session->set_userdata($sessionData); $this->load->view('test', $sessionData); } Currently, obviously, my controller gets the value of each input, writing over previous values in its wake, leaving only a string of the final value. I need to store these, however, so I can print them on a subsequent page. What I imagine I'd love to do is extend the input class to be able to call $this-input-posts('goal'). Eventually I will need to store other arrays to session values. But I'm totally open to implementation suggestion. Thanks so much for any help you can give.
