  • Search engine solution for Django that actually works?

    - by prometheus
    The story so far: Decided to go with Xapian as search backend because it has all search-engine features I was looking for, knows about Unicode, stemming, has few dependencies and requires no bloated app-server installation on top of it. Tried Django and Haystack (plus xapian-haystack, the backend glue code to tie Haystack to Xapian) because it was advertised on quite some blogs as "working". Did not work. Neither django-haystack nor the xapian-haystack project provide a version combination that actually works together. MASTER from both projects yields an error from Xapian, so it's not stable at all. Haystack 1.0.1 and xapian-haystack 1.0.x/1.1.0 are not API-compatible. Plus, in a minimally working installation of Haystack 1.0.1 and xapian-haystack MASTER, any complex query yields zero results due to errors in either django-haystack or xapian-haystack (I double-verified this), maybe because the unit-tests actually test very simple cases, and no edge-cases at all. Tried Djapian. The source-code is riddled with spelling errors (mind you, in variable names, not comments), documentation is also riddled with ambiguities and outdated information that will never lead to a working installation. Not surprisingly, users rarely ask for features but how to get it working in the first place. Next on the plate: exploring Solr (installing a Java environment plus Tomcat gives me headaches, the machine is RAM- and CPU-constrained), or Lucene (slightly less headaches, but still). Before I proceed spending more time with a solution that might or might not work as advertised, I'd like to know: Did anyone ever get an actual, real-world search solution working in Django? I'm serious. I find it really frustrating reading about "large problems mostly solved", and then realizing that you will never get a working installation from the source-code because, actually, all bloggers dealing with those "mostly solved problems" never went past basic installation and copy-pasting the official tutorials. So here are the requirements: must be able to search for 10-100 terms in one query must handle + (term must be present) and - (term must not be present), AND/OR must handle arbitrary grouping (i.e. parentheses around AND/OR) must allow for Django-ORM filtering before or after fulltext-search (i.e. pre-/post-processing of results with the full set of filters that Django knows about) alternatively, there must be a facility to bulk-fetch the result set and transform it into a QuerySet should be light on the machine, so preferably no humongous JVM and Java-based app-server installation Is there anything out there that does this? I'm not interested in anecdotal evidence, or references to some blog posts that claim it should be working. I'd like to hear from someone who actually has a fully-functional setup working in the real world, under real conditions, with real queries. EDIT: Let me repeat again that I'm not so much interested in anecdotal evidence that someone, somewhere has a somewhat running installation working with unspecified properties. I already went there, I read all the blog posts, mailing lists, I contacted the authors, but when it came to actual implementation of real-world scenarios, nothing ever worked as advertised. Also, and a user below brought that point up as well, considering the TCO of any project, I'm definitely not interested in hearing that someone, somewhere was able to pull it off once a vendor parachuted in an unknown number of specialists to monkey-patch the whole installation with specific domain-knowledge that's documented nowhere. So, please, if you claim you have a working installation that actually satisfies minimum requirements for a full-fledged search (see requirements above), please provide the following so that we can all benefit from a search solution for Django that actually solves the problem: exact Linux distribution, release version, exact release version of Haystack (or equivalent) and release version of search backend, exact release version of the search engine publicly (!) available documentation how to set up all components exactly in the way that your installation was set up such that the minimal requirements above are met. Thank you.

  • jQuery JSON encode set of input values

    - by gurun8
    I need tp serialize a group of input elements but I can't for the life of me figure out this simple task. I can successfully iterate through the targeted inputs using: $("#tr_Features :input").each(function() { ... } Here's my code, that doesn't work: var features = new Array(); $("#tr_Features :input").each(function() { features += {$(this).attr("name"): $(this).val()}; } Serializing the entire form won't give me what I need. The form has much more than this subset of inputs. This seems like it should be a pretty straightforward task but apparently programming late into a Friday afternoon isn't a good thing. If it's helpful, here's the form inputs I'm targeting: <table cellspacing="0" border="0" id="TblGrid_list" class="EditTable" cellpading="0"> <tbody><tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Cable Family</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:8" name="feature_id:8"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Material</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:9" name="feature_id:9"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Thread Size</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:10" name="feature_id:10"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Attachment Style</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:11" name="feature_id:11"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Feature</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:12" name="feature_id:12"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Comments</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:13" name="feature_id:13"></td> </tr> </tbody></table>

  • IE8 Crashes Strangely on JavaScript Popup

    - by dkris
    Hi, I am facing a strange issue after the popup is created onclick. The popup opens up but hangs immediately on IE8 (works fine on all the other browsers including IE6). But on adding the alertbox as show in the JavaScript code, the popup works fine. I am using **https** and not **http** and i feel popup is not able to load the JS file because of SSL. Here is the how i am generating the onclick event: <a id="forgotPasswordLink" href="#" onclick="openSupportPage();"> Some Text </a> The onclick function is defined this way: function openSupportPage() { var features = "width=700,height=400,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes"; var winId = window.open('', '', features); winId.focus(); winId.document.open(); winId.document.write('<html><head><title>' + document.title + '</title><link rel="stylesheet" href="./css/default.css" type="text/css">\n'); var is_ie6 = ( window.external && typeof window.XMLHttpRequest == "undefined"); alert(is_ie6);/*The JS include below*/ /*works in popup only with this alert box.*/ /*else IE8 Hangs*/ winId.document.write('<script src="../js/tiny_mce/tiny_mce.js" type="text/javascript">Script_IE8</script>\n'); winId.document.write('<script type="text/javascript">\n'); winId.document.write('function inittextarea() {\n'); winId.document.write('tinyMCE.init({ \n'); winId.document.write('elements : "content",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('mode : "exact",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('setup : function(ed) {\n'); winId.document.write('ed.onInit.add(function() {\n'); winId.document.write('tinyMCE.activeEditor.execCommand("mceToggleVisualAid");\n'); winId.document.write('});\n'); winId.document.write('}\n'); winId.document.write('});}</script>\n'); winId.document.write('</head><body onload="inittextarea()">\n'); winId.document.write(' \n'); var hiddenFrameHTML = document.getElementById("HiddenFrame").innerHTML; hiddenFrameHTML = hiddenFrameHTML.replace(/&amp;/gi, "&"); hiddenFrameHTML = hiddenFrameHTML.replace(/&lt;/gi, "<"); hiddenFrameHTML = hiddenFrameHTML.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML); winId.document.write('<textarea id="content" rows="10" style="width:100%">\n'); winId.document.write(document.getElementById(top.document.forms[0].id + ":supportStuff").innerHTML); winId.document.write('</textArea>\n'); var hiddenFrameHTML2 = document.getElementById("HiddenFrame2").innerHTML; hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&amp;/gi, "&"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&lt;/gi, "<"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML2); winId.document.write('</body></html>\n'); winId.document.close(); } Please help me on this one.

  • In Ruby, how to I read memory values from an external process?

    - by grg-n-sox
    So all I simply want to do is make a Ruby program that reads some values from known memory address in another process's virtual memory. Through my research and basic knowledge of hex editing a running process's x86 assembly in memory, I have found the base address and offsets for the values in memory I want. I do not want to change them; I just want to read them. I asked a developer of a memory editor how to approach this abstract of language and assuming a Windows platform. He told me the Win32API calls for OpenProcess, CreateProcess, ReadProcessMemory, and WriteProcessMemory were the way to go using either C or C++. I think that the way to go would be just using the Win32API class and mapping two instances of it; One for either OpenProcess or CreateProcess, depending on if the user already has th process running or not, and another instance will be mapped to ReadProcessMemory. I probably still need to find the function for getting the list of running processes so I know which running process is the one I want if it is running already. This would take some work to put all together, but I am figuring it wouldn't be too bad to code up. It is just a new area of programming for me since I have never worked this low level from a high level language (well, higher level than C anyways). I am just wondering of the ways to approach this. I could just use a bunch or Win32API calls, but that means having to deal with a bunch of string and array pack and unpacking that is system dependant I want to eventually make this work cross-platform since the process I am reading from is produced from an executable that has multiple platform builds, (I know the memory address changes from system to system. The idea is to have a flat file that contains all memory mappings so the Ruby program can just match the current platform environment to the matching memory mapping.) but from the looks of things I'll just have to make a class that wraps whatever is the current platform's system shared library memory related function calls. For all I know, there could already exist a Ruby gem that takes care of all of this for me that I am just not finding. I could also possibly try editing the executables for each build to make it so whenever the memory values I want to read from are written to by the process, it also writes a copy of the new value to a space in shared memory that I somehow have Ruby make an instance of a class that is a pointer under the hood to that shared memory address and somehow signal to the Ruby program that the value was updated and should be reloaded. Basically a interrupt based system would be nice, but since the purpose of reading these values is just to send to a scoreboard broadcasted from a central server, I could just stick to a polling based system that sends updates at fixed time intervals. I also could just abandon Ruby altogether and go for C or C++ but I do not know those nearly as well. I actually know more x86 than C++ and I only know C as far as system independent ANSI C and have never dealt with shared system libraries before. So is there a gem or lesser known module available that has already done this? If not, then any additional information as to how to accomplish this would be nice. I guess, long story short, how do I do all this? Thanks in advance, Grg PS: Also a confirmation that those Win32API calls should be aimed at the kernel32.dll library would be nice.

  • Pure JSP without mixing HTML, by writing html as Java-like code

    - by ADTC
    Please read before answering. This is a fantasy programming technique I'm dreaming up. I want to know if there's anything close in real life. The following JSP page: <% html { head { title {"Pure fantasy";} } body { h1 {"A heading with double quote (\") character";} p {"a paragraph";} String s = "a paragraph in string. the date is "; p { s; new Date().toString(); } table (Border.ZERO, new Padding(27)) { tr { for (int i = 0; i < 10; i++) { td {i;} } } } } } %> could generate the following HTML page: <html> <head> <title>Pure fantasy</title> </head> <body> <h1>A heading with double quote (") character</h1> <p>a paragraph</p> <p>a paragraph in string. the date is 11 December 2012</p> <table border="0" padding="27"> <tr> <td>0</td> <td>1</td> <td>2</td> <td>3</td> <td>4</td> <td>5</td> <td>6</td> <td>7</td> <td>8</td> <td>9</td> </tr> </table> </body> </html> The thing about this fantasy is it reuses the same old Java programming language technique that enable customized keywords used in a way similar to if-else-then, while, try-catch etc to represent html tags in a non-html way that can easily be checked for syntactic correctness, and most importantly can easily be mixed up with regular Java code without being lost in a sea of <%, %>, <%=, out.write(), etc. An added feature is that strings can directly be placed as commands to print out into generated HTML, something Java doesn't support (where pure strings have to be assigned to variables before use). Is there anything in real life that comes close? If not, is it possible to define customized keywords in Java or JSP? Or do I have to create an entirely new programming language for that? What problems do you see with this kind of setup? PS: I know you can use HTML libraries to construct HTML using Java code, but the problem with such libraries is, the source code itself doesn't have a readable HTML representation like the code above does - if you get what I mean.

  • Win32: IProgressDialog will not disappear until you mouse over it.

    - by Ian Boyd
    i'm using the Win32 progress dialog. The damnest thing is that when i call: progressDialog.StopProgressDialog(); it doesn't disappear. It stays on screen until the user moves her mouse over it - then it suddenly disappers. The call to StopProgressDialog returns right away (i.e. it's not a synchronous call). i can prove this by doing things after the call has returned: private void button1_Click(object sender, EventArgs e) { //Force red background to prove we've started this.BackColor = Color.Red; this.Refresh(); //Start a progress dialog IProgressDialog pd = (IProgressDialog)new ProgressDialog(); pd.StartProgressDialog(this.Handle, null, PROGDLG.Normal, IntPtr.Zero); //The long running operation System.Threading.Thread.Sleep(10000); //Stop the progress dialog pd.SetLine(1, "Stopping Progress Dialog", false, IntPtr.Zero); pd.StopProgressDialog(); pd = null; //Return form to normal color to prove we've stopped. this.BackColor = SystemColors.Control; this.Refresh(); } The form: starts gray turns red to show we've stared turns back to gray color to show we've called stop So the call to StopProgressDialog has returned, except the progress dialog is still sitting there, mocking me, showing the message: Stopping Progress Dialog Doesn't Appear for 10 seconds Additionally, the progress dialog does not appear on screen until the System.Threading.Thread.Sleep(10000); ten second sleep is over. Not limited to .NET WinForms The same code also fails in Delphi, which is also an object wrapper around Window's windows: procedure TForm1.Button1Click(Sender: TObject); var pd: IProgressDialog; begin Self.Color := clRed; Self.Repaint; pd := CoProgressDialog.Create; pd.StartProgressDialog(Self.Handle, nil, PROGDLG_NORMAL, nil); Sleep(10000); pd.SetLine(1, StringToOleStr('Stopping Progress Dialog'), False, nil); pd.StopProgressDialog; pd := nil; Self.Color := clBtnFace; Self.Repaint; end; PreserveSig An exception would be thrown if StopProgressDialog was failing. Most of the methods in IProgressDialog, when translated into C# (or into Delphi), use the compiler's automatic mechanism of converting failed COM HRESULTS into a native language exception. In other words the following two signatures will throw an exception if the COM call returned an error HRESULT (i.e. a value less than zero): //C# void StopProgressDialog(); //Delphi procedure StopProgressDialog; safecall; Whereas the following lets you see the HRESULT's and react yourself: //C# [PreserveSig] int StopProgressDialog(); //Delphi function StopProgressDialog: HRESULT; stdcall; HRESULT is a 32-bit value. If the high-bit is set (or the value is negative) it is an error. i am using the former syntax. So if StopProgressDialog is returning an error it will be automatically converted to a language exception. Note: Just for SaG i used the [PreserveSig] syntax, the returned HRESULT is zero; MsgWait? The symptom is similar to what Raymond Chen described once, which has to do with the incorrect use of PeekMessage followed by MsgWaitForMultipleObjects: "Sometimes my program gets stuck and reports one fewer record than it should. I have to jiggle the mouse to get the value to update. After a while longer, it falls two behind, then three..." But that would mean that the failure is in IProgressDialog, since it fails equally well on CLR .NET WinForms and native Win32 code.

  • Extjs4: editable rowbody

    - by peter
    in my first ExtJs4 project i use a editable grid with the feature rowbody to have a big textfield displayed under each row. I want it to be editable on a dblclick. I succeeded in doing so by replacing the innerHTML of the rowbody by a textarea but the special keys don't do what they are supposed to do (move the cursor). If a use the textarea in a normal field i don't have this probem. Same problem in IE7 and FF4 gridInfo = Ext.create('Ext.ux.LiveSearchGridPanel', { id: 'gridInfo', height: '100%', width: '100%', store: storeInfo, columnLines: true, selType: 'cellmodel', columns: [ {text: "Titel", flex: 1, dataIndex: 'titel', field:{xtype:'textfield'}}, {text: "Tags", id: "tags", flex: 1, dataIndex: 'tags', field:{xtype:'textfield'}}, {text: "Hits", dataIndex: 'hits'}, {text: "Last Updated", renderer: Ext.util.Format.dateRenderer('d/m/Y'), dataIndex: 'lastChange'} ], plugins: [ Ext.create('Ext.grid.plugin.CellEditing', { clicksToEdit: 1 }) ], features: [ { ftype: 'rowbody', getAdditionalData: function(data, idx, record, orig) { var headerCt = this.view.headerCt, colspan = headerCt.getColumnCount(); return { rowBody: data.desc, //the big textfieldvalue, can't use a textarea here 8< rowBodyCls: this.rowBodyCls, rowBodyColspan: colspan }; } }, {ftype: 'rowwrap'} ] }); me.on('rowbodydblclick', function(gridView, el, event, o) { ... rb = td.down('.x-grid-rowbody').dom; var value = rb.innerText?rb.innerText:rb.textContent; rb.innerHTML = ''; Ext.create('Ext.form.field.TextArea', { id: 'textarea1', value : value, renderTo: rb, border: false, enterIsSpecial: true, enableKeyEvents: true, disableKeyFilter: true, listeners: { 'blur': function(el, o) { rb.innerHTML = el.value; }, 'specialkey': function(field, e){ console.log(e.keyCode); //captured but nothing happens } } }).show(); damn, can't publish my own solution, looks like somebody else has to answer, anyway, here is the function that works function editDesc(me, gridView, el, event, o) { var width = Ext.fly(el).up('table').getWidth(); var rb = event.target; var value = rb.innerText?rb.innerText:rb.textContent; rb.innerHTML = '' var txt = Ext.create('Ext.form.field.TextArea', { value : value, renderTo: rb, border: false, width: width, height: 300, enterIsSpecial: true, disableKeyFilter: true, listeners: { 'blur': function(el, o) { var value = el.value.replace('\n','<br>') rb.innerHTML = value; }, 'specialkey': function(field, e){ e.stopPropagation(); } } }); var txtTextarea = Ext.fly(rb).down('textarea'); txtTextarea.dom.style.color = 'blue'; txtTextarea.dom.style.fontSize = '11px'; } Hi Molecule Man, as an alternative to the approach above i tried the Ext.Editor. It works but i want it inline but when i render it to the rowbody, the field blanks and i have no editor, any ideas ? gridInfo = Ext.create('Ext.grid.Panel', { id: 'gridInfo', height: '100%', width: '100%', store: storeInfo, columnLines: true, selType: 'cellmodel', viewConfig: {stripeRows: false, trackOver: true}, columns: [ {text: "Titel", flex: 1, dataIndex: 'titel', field:{xtype:'textfield'}}, ... {text: "Last Updated", renderer: Ext.util.Format.dateRenderer('d/m/Y'), dataIndex: 'lastChange'} ], plugins: [ Ext.create('Ext.grid.plugin.CellEditing', { clicksToEdit: 1 }) ], features: [ { ftype: 'rowbody', getAdditionalData: function(data, idx, record, orig) { var headerCt = this.view.headerCt, colspan = headerCt.getColumnCount(); return { rowBody: data.desc, rowBodyCls: this.rowBodyCls, rowBodyColspan: colspan }; } } ], listeners:{ rowbodyclick: function(gridView, el, event) { //werkt editDesc(this, gridView, el, event); } } }); function editDesc(me, gridView, el, event, o) { var rb = event.target; me.txt = new Ext.Editor({ field: {xtype: 'textarea'}, updateEl: true, cancelOnEsc: true, floating: true, renderTo: rb //when i do this, the field becomes empty and i don't get the editor }); me.txt.startEdit(el); }

    So i just made my first RSS feed, or so i tought, in combination with CI. Now my view DOES display the top of my rss page (Title and Description), But all items are omitted. When i rightclick-view source it DOES contain all the items within the item tags. Can anyone help me? View (rss.php): <?php echo '<?xml version="1.0" encoding="'.$encoding.'"?>'."\n"; ?> <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:admin="http://webns.net/mvcb/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:content="http://purl.org/rss/1.0/modules/content/"> <channel> <title><?php echo $feed_name; ?></title> <link><?php echo $feed_url; ?></link> <description><?php echo $page_description; ?></description> <dc:language><?php echo $page_language; ?></dc:language> <dc:creator><?php echo $creator_email; ?></dc:creator> <dc:rights>Copyright <?php echo gmdate("%Y", time()); ?></dc:rights> <dc:date><?php echo gmdate("%Y-%m-&#xdT;%H:%i:%s%Q", time()); ?></dc:date> <admin:generatorAgent rdf:resource="http://www.codeigniter.com/" /> <?php foreach($items as $entry): ?> <?php $entry_url = base_url().$this->lang->lang().$localized_news[$this->lang->lang()].'/'.print_date(strtotime($entry->published), "{year}/{month2}").'/'.$entry->slug; ?> <item> <title><?php echo xml_convert($entry->title); ?></title> <link><?php echo $entry_url; ?></link> <guid><?php echo $entry_url; ?></guid> <description><?php echo $entry->summary; ?></description> <pubDate><?php echo date('r', $entry->published); ?></pubDate> </item> <?php endforeach; ?> </channel> This is what the output looks like: screenshot and in the source, every item needed to be displayed is there. with <item> <link> <description> <guid> and <pubdate> tags. Ive been looking for the cause for about 1.5 hours now. and i cant find anything. Can someone tell me if i did anything wrong? Appreciate the help! ~Menno

  • Clickonce downloading the deploy files via HTTP and not HTTPS

    - by Scott Manning
    I am working on a project to deploy a project via clickonce. The website where these files are housed will only accept HTTPS traffic and if you attempt to connect via HTTP, our siteminder agent will redirect you to a HTTPS login form. We cannot disable the siteminder agent or enable HTTP for security reasons. In the application file, I have a codebase that references an absolute path to the manifest and it is via HTTPS <dependency> <dependentAssembly dependencyType="install" codebase="https://psaportal.ilab.test.com/testprinting/Application_Files/testprint_1_0_0_1/testprint.exe.manifest" size="10147"> <assemblyIdentity name="testprint.exe" version="1.0.0.1" publicKeyToken="9a078649ee05e0e7" language="neutral" processorArchitecture="msil" type="win32" /> <hash> <dsig:Transforms> <dsig:Transform Algorithm="urn:schemas-microsoft-com:HashTransforms.Identity" /> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <dsig:DigestValue>2nch1T0SmlAycmePobtg9F1qF7c=</dsig:DigestValue> </hash> </dependentAssembly> </dependency> In running wireshark and decoding the SSL traffic (I am using the server’s private key in wireshark to decrypt the SSL traffic). I see the request to the application’s manifest file is via HTTPS (This is a good thing). But when the clickonce tries to download the testprint.exe.deploy and the other respective files, it is always via HTTP and the siteminder jumps in and redirects the requests which kills the clickonce install with errors. I have tried to specific an absolute codebase reference in the manifest file, but then I start getting entrypoint errors when the manifest is downloaded by the Clickonce installer. The current dependency section from the manifest file looks like the following: <dependency> <dependentAssembly dependencyType="install" allowDelayedBinding="true" codebase="testprint.exe" size="107008"> <assemblyIdentity name="testprint" version="1.0.0.1" language="neutral" processorArchitecture="msil" /> <hash> <dsig:Transforms> <dsig:Transform Algorithm="urn:schemas-microsoft-com:HashTransforms.Identity" /> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> <dsig:DigestValue>dm2nJsu/5UyaEXSDmnISwfnE9MM=</dsig:DigestValue> </hash> </dependentAssembly> </dependency> I have verified that the website where the application, manifest and deploy files are all under the same URL and the SSL certificate is a valid certificate. We have tried about every combination of generating application and manifest files as we a dream up and are looking for other solutions. The application is using .NET 3.5 and we have tried building the application and manifest files via VS2008, VS2010 and mage with no success. Does anyone know how to get all of the deploy files to always download via HTTPS?

  • Error data: line 2 column 1 when using pycurl with gzip stream

    - by Sagar Hatekar
    Thanks for reading. Background: I am trying to read a streaming API feed that returns data in JSON format, and then storing this data to a pymongo collection. The streaming API requires a "Accept-Encoding" : "Gzip" header. What's happening: Code fails on json.loads and outputs - Extra data: line 2 column 1 - line 4 column 1 (char 1891 - 5597) (Refer Error Log below) This does NOT happen while parsing every JSON object - it happens at random. My guess is I am encountering some weird JSON object after every "x" proper JSON objects. I did reference how to use pycurl if requested data is sometimes gzipped, sometimes not? and Encoding error while deserializing a json object from Google but so far have been unsuccessful at resolving this error. Could someone please help me out here? Error Log: Note: The raw dump of the JSON object below is basically using the repr() method.

  • Temporary "Backup" of SharePoint Content During Feature and Solution Deployment

    - by ccomet
    I need to decide on a method for storing a subset of the content in a SharePoint site, so that when I delete and recreate certain lists as part of a feature activation, I can re-insert all of this content back where it should belong. I have an idea myself, but I don't know if it's the only method and more importantly, the right method. My client has me creating a SharePoint system for them to communicate with their clients. The business process has maybe 5 stages in it (maybe it's more, I don't even know because they don't tell me everything), and the current system I've written over the past months is maybe 2 stages through. This meets our deadline of completing those systems by Monday next week... but at that point my client is planning on making the site live from that point. In effect, their work with their clients will be running parallel with my work for them. As I complete my own work on a separate test server, I'll push each following stage of the process onto the live server. Scheduled downtimes during non-business times (like a weekend) will be available for me to perform these pushes. Keeping pace so that my development is faster than the actual business process is my own problem and off-topic... so let's get back to the problem I stated at the start of this post. In this system, we have sets of features which will create lists for their associated content types and field types when activated, and delete these lists when the feature is deactivated. Most updates don't need to deactivate and reactivate these features, such as workflow changes, custom actions, custom forms, and similar ilk. But there are some parts which do require this. On my test server, it's okay for me to obliterate lists, but once the site is live and there's real correspondence data, it's absolutely unacceptable to do this. So when I need to implement a new change in functionality, I need to be able to store the currently present data in several lists, deactivate the feature, reactivate the feature, and restore all of this data. Perhaps I have hoist myself by my own petard with the feature system I implemented. Unfortunately, the necessity to later on make several of these "project sites" meant I had to do a lot of my code with the concept of "Can be deployed repeatedly" in mind. My current plan is to run through lists and libraries which will be affected by the particular feature that is to be reset. Files and all of their versions will be saved in a directory on the server. Then, a set of text files will be used to store all of the important field values for the items. This includes a lot of cross-list reference lookups that will need to be maintained, but that's simple enough. Then, I deactivate the feature, deploy the new solution, and reactivate the feature. We upload all of the files in the order specified by their versions and update them with the stored fields for those versions, so that we retain the version structure. As each one is first uploaded, the new ID is picked out, and all relevant lookups in the rest of the files are updated (in some manner that I make sure I don't re-update it later with an incorrect value, of course). After that, we run through all the rest of the items in the order most conducive to keeping the relational data correct. This roughly summarizes what my current plan is. To my advantage, there are no long running workflows in the system that will be affected by this, so there's nothing I will have to worry about making sure nothing is "still running" when I do this stuff. I don't really know all the cons of this approach... I can imagine they're quite hefty. But I'm unsure what other choices I even have, and my searches haven't turned up anything. Is there anyone who can think of a better idea? Or will anyone just tell me that I really have no other choice? Thanks in advance!

  • MVC keeping the PartialView in its own context - ignore the main view holding the partial view

    - by Mike
    I'm looking at the partialview components of the MVC Framework. i want my partial view to be handled in its own action and for the rest of the view to handle itself, but i'm getting an exception because the main page is not getting its view fired. Am i going around this the wrong way? My Main View (Jobs/Index.aspx): <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication3.Models.JobViewModel>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderPartial("JobListing", Model.Jobs); %> </asp:Content> The partialview (Jobs/JobListing.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<MvcApplication3.Models.Job>>" %> <table> <tr> <td> Job Title </td> <td> Job Location</td> </tr> <% foreach (var job in Model) { %> <tr> <td> <%= job.Title %> </td> <td> <%= job.Location %> </td> </tr> <% } %> <% Html.BeginForm("DoSomeStuff", "Job", null, FormMethod.Post); %> <%= Html.TextBox("SomeInfo") %> <button type="submit" id="submit" /> <% Html.EndForm(); %> The main controller for both the main view (Index) and the partialview (DoSomeStuff()) public class JobController : Controller { public ActionResult Index() { JobProvider provider = new JobProvider(Session); JobViewModel vm = new JobViewModel(); vm.Jobs = provider.GetJobs(); return View(vm); } public PartialViewResult DoSomeStuff() { return PartialView("JobListing"); } } As you can see in the partial view, it has its own form that posts to the Action called DoSomeStuff(). i want this action to handle any data submitted from that form. but when the form is submitted the main action (Index) does not fire and then i get an exception as the Model (.Models.JobViewModel) is not passed to the view that the partialview (JobListings) lives in. basically what im saying is, if i have a myview.aspx with lots of html.RenderPartialView('apartialview') that have forms in them, can i get it so these forms post to their own actions and the main view (with what ever model it inherits) is handled as well. Rather then having all the form submitting code in the main action for the view. am i do this wrong?

  • php slideshow sample

    - by serhio
    I try to do a simple image slideshow in php (just cycle images, no links, no other effects). after some googling I found the following in net: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; <?php $tel=0; $tst='.jpg'; $p= "./images"; $d = dir($p); $first = NULL; while (false !== ($entry = $d->read())) { if (stristr ($entry, $tst)) { $entry = $d->path."/".$entry; print ("x[$tel]='$entry';\n"); if ($first == NULL) { $first = $entry; } $tel++; } } $d->close(); ?> function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY > <!-- add html code here --> <?php print ("<IMG src='$first' id='pic' onload='timeF()' style='filter:blendTrans()' >"); ?> <!-- add html code here --> </BODY> </HTML> but it displays only the first image from the cycle.

  • Why isn't my algorithm for find the biggest and smallest inputs working?

    - by Matt Ellen
    I have started a new job, and with it comes a new language: Ironpython. Thankfully a good language :D Before starting I got to grips with Python on the whole, but that was only a week's worth of learning. Now I'm writing actual code. I've been charged with writing an algorithm that finds the best input parameter to collect data with. The basic algorithm is (as I've been instructed): Set the input parameter to a good guess Start collecting data When data is available stop collecting find the highest point If the point before this (i.e. for the previous parameter value) was higher and the point before that was lower then we've found the max otherwise the input parameter is increased by the initial guess. goto 2 If the max is found then the min needs to be found. To do this the algorithm carries on increasing the input, but by 1/10 of the max, until the current point is greater than the previous point and the point before that is also greater. Once the min is found then the algorithm stops. Currently I have a simplified data generator outputting the sin of the input, so that I know that the min value should be PI and the max value should be PI/2 The main Python code looks like this (don't worry, this is just for my edification, I don't write real code like this): import sys sys.path.append(r"F:\Programming Source\C#\PythonHelp\PythonHelp\bin\Debug") import clr clr.AddReferenceToFile("PythonHelpClasses.dll") import PythonHelpClasses from PHCStruct import Helper from System import Math helper = Helper() def run(): b = PythonHelpClasses.Executor() a = PythonHelpClasses.HasAnEvent() b.Input = 0.0 helper.__init__() def AnEventHandler(e): b.Stop() h = helper h.lastLastVal, h.lastVal, h.currentVal = h.lastVal, h.currentVal, e.Number if h.lastLastVal < h.lastVal and h.currentVal < h.lastVal and h.NotPast90: h.NotPast90 = False h.bestInput = h.lastInput inputInc = 0.0 if h.NotPast90: inputInc = Math.PI/10.0 else: inputInc = h.bestInput/10.0 if h.lastLastVal > h.lastVal and h.currentVal > h.lastVal and h.NotPast180: h.NotPast180 = False if h.NotPast180: h.lastInput, b.Input = b.Input, b.Input + inputInc b.Start(a) else: print "Best input:", h.bestInput print "Last input:", h.lastInput b.Stop() a.AnEvent += AnEventHandler b.Start(a) PHCStruct.py: class Helper(): def __init__(self): self.currentVal = 0 self.lastVal = 0 self.lastLastVal = 0 self.NotPast90 = True self.NotPast180 = True self.bestInput = 0 self.lastInput = 0 PythonHelpClasses has two small classes I wrote in C# before I realised how to do it in Ironpython. Executor runs a delegate asynchronously while it's running member is true. The important code: public void Start(HasAnEvent hae) { running = true; RunDelegate r = new RunDelegate(hae.UpdateNumber); AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar = r.BeginInvoke(Input, ac, null); } public void Stop() { running = false; } public void UpdateDone(IAsyncResult ar) { RunDelegate r = (RunDelegate)((AsyncResult)ar).AsyncDelegate; r.EndInvoke(ar); if (running) { AsyncCallback ac = new AsyncCallback(UpdateDone); IAsyncResult ar2 = r.BeginInvoke(Input, ac, null); } } HasAnEvent has a function that generates the sin of its input and fires an event with that result as its argument. i.e.: public void UpdateNumber(double val) { AnEventArgs e = new AnEventArgs(Math.Sin(val)); System.Threading.Thread.Sleep(1000); if (null != AnEvent) { AnEvent(e); } } The sleep is in there just to slow things down a bit. The problem I am getting is that the algorithm is not coming up with the best input being PI/2 and the final input being PI, but I can't see why. Also the best and final inputs are different each time I run the programme. Can anyone see why? Also when the algorithm terminates the best and final inputs are printed to the screen multiple times, not just once. Can someone explain why?

  • In ASP.NET MVC, How do I make a partial view available to all controllers?

    - by Quakkels
    In ASP.NET MVC, How do I make a partial view available to all controllers? I want to create navigation that is common across the entire site, but when I place the Html.Action into my master page, it only works on views associated with 1 controller. Right now, I have a controller action defined like this: // GET: GetCategoriesPartial [ChildActionOnly] public ActionResult GetCategoriesPartial() { var category = CategoriesDataContext.GetCategories(); return PartialView(category); } And I've created my partial view like this: <%@ Import Namespace="wopr.Models" %> <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <ul> <% foreach (var cat in Model as IEnumerable<Category>) { %> <li><a href="/categories/Details/<%=cat.catID%>"><%=cat.catName%></a></li> <% } %> </ul> My Master Page looks like this: <%@ Import Namespace="wopr.Models" %> <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title> <link type="text/css" rel="Stylesheet" href="/Content/Site.css" /> </head> <body> <div class="wrap-all"> <div style="text-align:right;"> <a href="/">Home</a> | <a href="/games/">Games</a> | <a href="/games/Index2/1">Games <em>(paginated)</em></a> | <a href="/categories/">Categories</a> | <a href="/upload/">Upload</a> </div> <asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder> <!--This errors on any non-CategoryController page.--> <%= Html.Action("GetCategoriesPartial")%> <!----> </div> </body> </html> This code works as long as I'm viewing something handled by the CategoriesController. If I go to any view handled by a different controller, I get the exception: System.Web.HttpException: A public action method 'GetCategoriesPartial' was not found on controller 'wopr.Controllers.GamesController'. How do I make this partial view available to all the site's controllers? Thanks for any help. Quakkels

This is the page I am trying to log into: http://www.wcu.edu/11407.asp The website has the following form to login: <FORM method=post action=https://itapp.wcu.edu/BanAuthRedirector/Default.aspx><INPUT value=https://cf.wcu.edu/busafrs/catcard/idsearch.cfm type=hidden name=wcuirs_uri> <P><B>WCU ID Number<BR></B><INPUT maxLength=12 size=12 type=password name=id> </P> <P><B>PIN<BR></B><INPUT maxLength=20 type=password name=PIN> </P> <P></P> <P><INPUT value="Request Access" type=submit name=submit> </P></FORM> From this we know that I need to fill in the following fields: 1. name=id 2. name=PIN With the action: action=https://itapp.wcu.edu/BanAuthRedirector/Default.aspx This is the script I have written thus far: #!/usr/bin/python2 -W ignore import mechanize, cookielib from time import sleep url = 'http://www.wcu.edu/11407.asp' myId = '11111111111' myPin = '22222222222' # Browser #br = mechanize.Browser() #br = mechanize.Browser(factory=mechanize.DefaultFactory(i_want_broken_xhtml_support=True)) br = mechanize.Browser(factory=mechanize.RobustFactory()) # Use this because of bad html tags in the html... # Cookie Jar cj = cookielib.LWPCookieJar() br.set_cookiejar(cj) # Browser options br.set_handle_equiv(True) br.set_handle_gzip(True) br.set_handle_redirect(True) br.set_handle_referer(True) br.set_handle_robots(False) # Follows refresh 0 but not hangs on refresh > 0 br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1) # User-Agent (fake agent to google-chrome linux x86_64) br.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11'), ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'), ('Accept-Encoding', 'gzip,deflate,sdch'), ('Accept-Language', 'en-US,en;q=0.8'), ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.3')] # The site we will navigate into br.open(url) # Go though all the forms (for debugging only) for f in br.forms(): print f # Select the first (index two) form br.select_form(nr=2) # User credentials br.form['id'] = myId br.form['PIN'] = myPin br.form.action = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx' # Login br.submit() # Wait 10 seconds sleep(10) # Save to a file f = file('mycatpage.html', 'w') f.write(br.response().read()) f.close() Now the problem... For some odd reason the page I get back (in mycatpage.html) is the login page and not the expected page that displays my "cat cash balance" and "number of block meals" left... Does anyone have any idea why? Keep in mind that everything is correct with the header files and while the id and pass are not really 111111111 and 222222222, the correct values do work with the website (using a browser...) Thanks in advance EDIT Another script I tried: from urllib import urlopen, urlencode import urllib2 import httplib url = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx' myId = 'xxxxxxxx' myPin = 'xxxxxxxx' data = { 'id':myId, 'PIN':myPin, 'submit':'Request Access', 'wcuirs_uri':'https://cf.wcu.edu/busafrs/catcard/idsearch.cfm' } opener = urllib2.build_opener() opener.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11'), ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'), ('Accept-Encoding', 'gzip,deflate,sdch'), ('Accept-Language', 'en-US,en;q=0.8'), ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.3')] request = urllib2.Request(url, urlencode(data)) open("mycatpage.html", 'w').write(opener.open(request)) This has the same behavior...

  • Serializing WPF DataTemplates and {Binding Expressions} (from PowerShell?)

    - by Jaykul
    Ok, here's the deal: I have code that works in C#, but when I call it from PowerShell, it fails. I can't quite figure it out, but it's something specific to PowerShell. Here's the relevant code calling the library (assuming you've added a reference ahead of time) from C#: public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } Compiled into an executable, that works fine ... but if you call that method from PowerShell, it returns with no {Binding FullName} for the Text! add-type -path .\PoshWpf.dll [PoshWpf.Test]::Main() I've pasted below the entire code for the library, all wrapped up in a PowerShell Add-Type call so you can just compile it by pasting it into PowerShell (you can leave off the first and last lines if you want to paste it into a new console app in Visual Studio. To output (from PowerShell 2) as an executable, just change the -OutputType parameter to ConsoleApplication and the -OutputAssembly to PoshWpf.exe (or something). Thus, you can see that running the SAME CODE from the executable gives you the correct output. But running the two lines as above or manually calling [PoshWpf.XamlHelper]::RoundTripXaml or [PoshWpf.XamlHelper]::ConvertToXaml from PowerShell just doesn't seem to work at all ... HELP?! Add-Type -TypeDefinition @" using System; using System.ComponentModel; using System.Globalization; using System.Linq; using System.Windows; using System.Windows.Data; using System.Windows.Markup; namespace PoshWpf { public class Test { [STAThread] public static void Main() { Console.WriteLine( PoshWpf.XamlHelper.RoundTripXaml( "<TextBlock Text=\"{Binding FullName}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"/>" ) ); } } public class BindingTypeDescriptionProvider : TypeDescriptionProvider { private static readonly TypeDescriptionProvider _DEFAULT_TYPE_PROVIDER = TypeDescriptor.GetProvider(typeof(Binding)); public BindingTypeDescriptionProvider() : base(_DEFAULT_TYPE_PROVIDER) { } public override ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance) { ICustomTypeDescriptor defaultDescriptor = base.GetTypeDescriptor(objectType, instance); return instance == null ? defaultDescriptor : new BindingCustomTypeDescriptor(defaultDescriptor); } } public class BindingCustomTypeDescriptor : CustomTypeDescriptor { public BindingCustomTypeDescriptor(ICustomTypeDescriptor parent) : base(parent) { } public override PropertyDescriptorCollection GetProperties(Attribute[] attributes) { PropertyDescriptor pd; var pdc = new PropertyDescriptorCollection(base.GetProperties(attributes).Cast<PropertyDescriptor>().ToArray()); if ((pd = pdc.Find("Source", false)) != null) { pdc.Add(TypeDescriptor.CreateProperty(typeof(Binding), pd, new Attribute[] { new DefaultValueAttribute("null") })); pdc.Remove(pd); } return pdc; } } public class BindingConverter : ExpressionConverter { public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType) { return (destinationType == typeof(MarkupExtension)) ? true : false; } public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType) { if (destinationType == typeof(MarkupExtension)) { var bindingExpression = value as BindingExpression; if (bindingExpression == null) throw new Exception(); return bindingExpression.ParentBinding; } return base.ConvertTo(context, culture, value, destinationType); } } public static class XamlHelper { static XamlHelper() { // this is absolutely vital: TypeDescriptor.AddProvider(new BindingTypeDescriptionProvider(), typeof(Binding)); TypeDescriptor.AddAttributes(typeof(BindingExpression), new Attribute[] { new TypeConverterAttribute(typeof(BindingConverter)) }); } public static string RoundTripXaml(string xaml) { return XamlWriter.Save(XamlReader.Parse(xaml)); } public static string ConvertToXaml(object wpf) { return XamlWriter.Save(wpf); } } } "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType Library -OutputAssembly PoshWpf.dll Again, you can get an executable by just altering the last line like so: "@ -language CSharpVersion3 -reference PresentationCore, PresentationFramework, WindowsBase -OutputType ConsoleApplication -OutputAssembly PoshWpf.exe

  • Business rule validation of hierarchical list of objects ASP.NET MVC

    - by SergeanT
    I have a list of objects that are organized in a tree using a Depth property: public class Quota { [Range(0, int.MaxValue, ErrorMessage = "Please enter an amount above zero.")] public int Amount { get; set; } public int Depth { get; set; } [Required] [RegularExpression("^[a-zA-Z]+$")] public string Origin { get; set; } // ... another properties with validation attributes } For data example (amount - origin) 100 originA 200 originB 50 originC 150 originD the model data looks like: IList<Quota> model = new List<Quota>(); model.Add(new Quota{ Amount = 100, Depth = 0, Origin = "originA"); model.Add(new Quota{ Amount = 200, Depth = 0, Origin = "originB"); model.Add(new Quota{ Amount = 50, Depth = 1, Origin = "originC"); model.Add(new Quota{ Amount = 150, Depth = 1, Orinig = "originD"); Editing of the list Then I use Editing a variable length list, ASP.NET MVC 2-style to raise editing of the list. Controller actions QuotaController.cs: public class QuotaController : Controller { // // GET: /Quota/EditList public ActionResult EditList() { IList<Quota> model = // ... assigments as in example above; return View(viewModel); } // // POST: /Quota/EditList [HttpPost] public ActionResult EditList(IList<Quota> quotas) { if (ModelState.IsValid) { // ... save logic return RedirectToAction("Details"); } return View(quotas); // Redisplay the form with errors } // ... other controller actions } View EditList.aspx: <%@ Page Title="" Language="C#" ... Inherits="System.Web.Mvc.ViewPage<IList<Quota>>" %> ... <h2>Edit Quotas</h2> <%=Html.ValidationSummary("Fix errors:") %> <% using (Html.BeginForm()) { foreach (var quota in Model) { Html.RenderPartial("QuotaEditorRow", quota); } %> <% } %> ... Partial View QuotaEditorRow.ascx: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Quota>" %> <div class="quotas" style="margin-left: <%=Model.Depth*45 %>px"> <% using (Html.BeginCollectionItem("Quotas")) { %> <%=Html.HiddenFor(m=>m.Id) %> <%=Html.HiddenFor(m=>m.Depth) %> <%=Html.TextBoxFor(m=>m.Amount, new {@class = "number", size = 5})%> <%=Html.ValidationMessageFor(m=>m.Amount) %> Origin: <%=Html.TextBoxFor(m=>m.Origin)%> <%=Html.ValidationMessageFor(m=>m.Origin) %> ... <% } %> </div> Business rule validation How do I implement validation of business rule: Amount of quota and sum of amounts of nested quotas should equal (e.a. 200 = 50 + 150 in example)? I want to appropriate inputs Html.TextBoxFor(m=>m.Amount) be highlighted red if the rule is broken for it. In example if user enters not 200, but 201 - it should be red on submit. Using sever validation only. Thanks a lot for any advise.

  • Optimizing Python code with many attribute and dictionary lookups

    - by gotgenes
    I have written a program in Python which spends a large amount of time looking up attributes of objects and values from dictionary keys. I would like to know if there's any way I can optimize these lookup times, potentially with a C extension, to reduce the time of execution, or if I need to simply re-implement the program in a compiled language. The program implements some algorithms using a graph. It runs prohibitively slowly on our data sets, so I profiled the code with cProfile using a reduced data set that could actually complete. The vast majority of the time is being burned in one function, and specifically in two statements, generator expressions, within the function: The generator expression at line 202 is neighbors_in_selected_nodes = (neighbor for neighbor in node_neighbors if neighbor in selected_nodes) and the generator expression at line 204 is neighbor_z_scores = (interaction_graph.node[neighbor]['weight'] for neighbor in neighbors_in_selected_nodes) The source code for this function of context provided below. selected_nodes is a set of nodes in the interaction_graph, which is a NetworkX Graph instance. node_neighbors is an iterator from Graph.neighbors_iter(). Graph itself uses dictionaries for storing nodes and edges. Its Graph.node attribute is a dictionary which stores nodes and their attributes (e.g., 'weight') in dictionaries belonging to each node. Each of these lookups should be amortized constant time (i.e., O(1)), however, I am still paying a large penalty for the lookups. Is there some way which I can speed up these lookups (e.g., by writing parts of this as a C extension), or do I need to move the program to a compiled language? Below is the full source code for the function that provides the context; the vast majority of execution time is spent within this function. def calculate_node_z_prime( node, interaction_graph, selected_nodes ): """Calculates a z'-score for a given node. The z'-score is based on the z-scores (weights) of the neighbors of the given node, and proportional to the z-score (weight) of the given node. Specifically, we find the maximum z-score of all neighbors of the given node that are also members of the given set of selected nodes, multiply this z-score by the z-score of the given node, and return this value as the z'-score for the given node. If the given node has no neighbors in the interaction graph, the z'-score is defined as zero. Returns the z'-score as zero or a positive floating point value. :Parameters: - `node`: the node for which to compute the z-prime score - `interaction_graph`: graph containing the gene-gene or gene product-gene product interactions - `selected_nodes`: a `set` of nodes fitting some criterion of interest (e.g., annotated with a term of interest) """ node_neighbors = interaction_graph.neighbors_iter(node) neighbors_in_selected_nodes = (neighbor for neighbor in node_neighbors if neighbor in selected_nodes) neighbor_z_scores = (interaction_graph.node[neighbor]['weight'] for neighbor in neighbors_in_selected_nodes) try: max_z_score = max(neighbor_z_scores) # max() throws a ValueError if its argument has no elements; in this # case, we need to set the max_z_score to zero except ValueError, e: # Check to make certain max() raised this error if 'max()' in e.args[0]: max_z_score = 0 else: raise e z_prime = interaction_graph.node[node]['weight'] * max_z_score return z_prime Here are the top couple of calls according to cProfiler, sorted by time. ncalls tottime percall cumtime percall filename:lineno(function) 156067701 352.313 0.000 642.072 0.000 bpln_contextual.py:204(<genexpr>) 156067701 289.759 0.000 289.759 0.000 bpln_contextual.py:202(<genexpr>) 13963893 174.047 0.000 816.119 0.000 {max} 13963885 69.804 0.000 936.754 0.000 bpln_contextual.py:171(calculate_node_z_prime) 7116883 61.982 0.000 61.982 0.000 {method 'update' of 'set' objects}

  • Future of VB.NET? [closed]

    - by Alex Yeung
    Hi all, I worked with C# for years. Last year, I changed my job and the company use VB.NET. Of course, theoretically C# and VB.NET are very similar and I easily adapted. However, I have worked for VB.NET for 1 year. I cannot see any future of VB.NET. As a programming language, it is so foo. Here is a list of what C# can do but VB.NET cannot Case insensitive variables how to think a new variable name? If I have a property called FolderPath, i need to establish another private variable called _folderPath or m_folderPath. In C#, FolderPath and folderPath are two variables. Moreover, it gets compile error if variable name is same as a class name. For example Dim guid = Guid.NewGuid(). (What the...) Again, I need to think a new variable name. Adhoc scope In C#, we could use {...} to create a adhoc scope and all resource in {...} will not affect the code outside. However there is not such syntax in VB.NET. I could only use If True Then and End If to make a local scope which is so unclear. In-Method Region Sometime, it is unavoidable to have a long long method. VB.NET does not support in-method region. I always need to scroll down for 1000 lines. It wastes my time. No multi-line string definition In C#, we could var s = @"..." to define a multi-line string. In VB.NET there is no direct method to do that. The indirect way is use XML-literal string. Dim s = <![CDATA[...]]>.Value. However it is unclear. No block comment In C#, we have line comment // and block comment /* ... */. However in VB.NET we only have line comment which is a very big trouble for me. No statement end symbol Statements are separated by line break in VB.NET; while statements are separated by ; in C#. Underscore I think many people know underscore _ is continue statement symbol. I really disagree with that. I know MS VB.NET language team is going to remove the underscore syntax from VB.NET. However what can we do now? Although underscore is removed in the future, what's the advantage of that? I cannot see any advantage! With scope With scope is an evil scope. Although it allows shorter statement, it is hard to trace. Default Namesapce in project level It is a nightmare for me. The only advantage of VB.NET is property initialization. I think C# cannot do that (correct me if I am wrong.) Public Property ThisIsMyProperty As String = "MyValue" Remarks: I don't think optional method parameters is an advantage of OOP. By those disadvantages, I cannot see the future of VB.NET. Anyone sees the future of VB.NET?

  • How to design a C / C++ library to be usable in many client languages?

    - by Brian Schimmel
    I'm planning to code a library that should be usable by a large number of people in on a wide spectrum of platforms. What do I have to consider to design it right? To make this questions more specific, there are four "subquestions" at the end. Choice of language Considering all the known requirements and details, I concluded that a library written in C or C++ was the way to go. I think the primary usage of my library will be in programs written in C, C++ and Java SE, but I can also think of reasons to use it from Java ME, PHP, .NET, Objective C, Python, Ruby, bash scrips, etc... Maybe I cannot target all of them, but if it's possible, I'll do it. Requirements It would be to much to describe the full purpose of my library here, but there are some aspects that might be important to this question: The library itself will start out small, but definitely will grow to enormous complexity, so it is not an option to maintain several versions in parallel. Most of the complexity will be hidden inside the library, though The library will construct an object graph that is used heavily inside. Some clients of the library will only be interested in specific attributes of specific objects, while other clients must traverse the object graph in some way Clients may change the objects, and the library must be notified thereof The library may change the objects, and the client must be notified thereof, if it already has a handle to that object The library must be multi-threaded, because it will maintain network connections to several other hosts While some requests to the library may be handled synchronously, many of them will take too long and must be processed in the background, and notify the client on success (or failure) Of course, answers are welcome no matter if they address my specific requirements, or if they answer the question in a general way that matters to a wider audience! My assumptions, so far So here are some of my assumptions and conclusions, which I gathered in the past months: Internally I can use whatever I want, e.g. C++ with operator overloading, multiple inheritance, template meta programming... as long as there is a portable compiler which handles it (think of gcc / g++) But my interface has to be a clean C interface that does not involve name mangling Also, I think my interface should only consist of functions, with basic/primitive data types (and maybe pointers) passed as parameters and return values If I use pointers, I think I should only use them to pass them back to the library, not to operate directly on the referenced memory For usage in a C++ application, I might also offer an object oriented interface (Which is also prone to name mangling, so the App must either use the same compiler, or include the library in source form) Is this also true for usage in C# ? For usage in Java SE / Java EE, the Java native interface (JNI) applies. I have some basic knowledge about it, but I should definitely double check it. Not all client languages handle multithreading well, so there should be a single thread talking to the client For usage on Java ME, there is no such thing as JNI, but I might go with Nested VM For usage in Bash scripts, there must be an executable with a command line interface For the other client languages, I have no idea For most client languages, it would be nice to have kind of an adapter interface written in that language. I think there are tools to automatically generate this for Java and some others For object oriented languages, it might be possible to create an object oriented adapter which hides the fact that the interface to the library is function based - but I don't know if its worth the effort Possible subquestions is this possible with manageable effort, or is it just too much portability? are there any good books / websites about this kind of design criteria? are any of my assumptions wrong? which open source libraries are worth studying to learn from their design / interface / souce? meta: This question is rather long, do you see any way to split it into several smaller ones? (If you reply to this, do it as a comment, not as an answer)
