  • Htaccess rewrite rule .aspx to .php

    - by Markus Ossi
    Background: I have a website that has been built with ASP.NET 2.0 and is on Windows hosting. I now have to rewrite my site in PHP and move it into Linux hosting. I have a lot of incoming links to my site from around the web that point directly into the old .aspx-pages. The site itself is very simple, one dynamic page and five static ones. I saved the static .aspx pages as .php-pages and rewrote the dynamic page in PHP. The dynamic page is called City.aspx and I have written it in PHP and it is now called City.php. On my old Windows hosting, I used ASP.NET's URL mapping for friendly URL. For example, incoming URL request for Laajakaista/Ypaja.aspx was mapped into City.aspx?CityID=981. My goal: To redirect all human visitors and search engines looking for the old .aspx pages into the new .php pages. I am thinking that the easiest way to redirect visitors into new pages will be by making a redirect, where all requests for .aspx-files will be redirected into .php filetypes. So, if someone asks for MYSITE/City.aspx?CityID=5, they will be taken into MYSITE/City.php?CityID=5 instead. However, I am having a lot of trouble getting this to work. So far this is what I have found: rewriterule ^([.]+)\.aspx$ http://www.example.com/$1.php [R=301,L] However, I think this can not handle the parameters after the filetype and I am also not quite sure what to put on front. To make things a bit more complicated, at my previous site I used friendly URL's so that I had a huge mapping file with mappings like this: <add url="~/Laajakaista/Ypaja.aspx" mappedUrl="~/City.aspx?CityID=981" /> <add url="~/Laajakaista/Aetsa.aspx" mappedUrl="~/City.aspx?CityID=988" /> <add url="~/Laajakaista/Ahtari.aspx" mappedUrl="~/City.aspx?CityID=989" /> <add url="~/Laajakaista/Aanekoski.aspx" mappedUrl="~/City.aspx?CityID=992" /> I tried to make a simple redirect like this: Redirect 301 Laajakaista/Aanekoski.aspx City.php?CityID=992 but was not able to get it to work. I ended up with an internal server error and a 50k .htaccess-file... Any help is greatly appreciated.

  • PHP mysqli wrapper: passing by reference with __call() and call_user_func_array()

    - by Dave
    Hi everyone. I'm a long running fan of stackoverflow, first time poster. I'd love to see if someone can help me with this. Let me dig in with a little code, then I'll explain my problem. I have the following wrapper classes: class mysqli_wrapper { private static $mysqli_obj; function __construct() // Recycles the mysqli object { if (!isset(self::$mysqli_obj)) { self::$mysqli_obj = new mysqli(MYSQL_SERVER, MYSQL_USER, MYSQL_PASS, MYSQL_DBNAME); } } function __call($method, $args) { return call_user_func_array(array(self::$mysqli_obj, $method), $args); } function __get($para) { return self::$mysqli_obj->$para; } function prepare($query) // Overloaded, returns statement wrapper { return new mysqli_stmt_wrapper(self::$mysqli_obj, $query); } } class mysqli_stmt_wrapper { private $stmt_obj; function __construct($link, $query) { $this->stmt_obj = mysqli_prepare($link, $query); } function __call($method, $args) { return call_user_func_array(array($this->stmt_obj, $method), $args); } function __get($para) { return $this->stmt_obj->$para; } // Other methods will be added here } My problem is that when I call bind_result() on the mysqli_stmt_wrapper class, my variables don't seem to be passed by reference and nothing gets returned. To illustrate, if I run this section of code, I only get NULL's: $mysqli = new mysqli_wrapper; $stmt = $mysqli->prepare("SELECT cfg_key, cfg_value FROM config"); $stmt->execute(); $stmt->bind_result($cfg_key, $cfg_value); while ($stmt->fetch()) { var_dump($cfg_key); var_dump($cfg_value); } $stmt->close(); I also get a nice error from PHP which tells me: PHP Warning: Parameter 1 to mysqli_stmt::bind_result() expected to be a reference, value given in test.php on line 48 I've tried to overload the bind_param() function, but I can't figure out how to get a variable number of arguments by reference. func_get_args() doesn't seem to be able to help either. If I pass the variables by reference as in $stmt->bind_result(&$cfg_key, &$cfg_value) it should work, but this is deprecated behaviour and throws more errors. Does anyone have some ideas around this? Thanks so much for your time.

  • WPF Open Combobox popup on Focus or GotFocus

    - by ashish.magroria
    Hi, I am trying to open the combobox popup when it is focused using Style/Event Trigger I used the following code in my Combobox control Template: <ControlTemplate x:Key="ComboBoxTemplate" TargetType="{x:Type ComboBox}"> <Grid > <ToggleButton Grid.Column="2" Template="{DynamicResource ComboBoxToggleButton}" x:Name="ToggleButton" Focusable="false" IsChecked="{Binding Path=IsDropDownOpen, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" ClickMode="Press"/> <ContentPresenter HorizontalAlignment="Left" Margin="3,3,23,3" x:Name="ContentSite" VerticalAlignment="Center" Content="{TemplateBinding SelectionBoxItem}" ContentTemplate="{TemplateBinding SelectionBoxItemTemplate}" ContentTemplateSelector="{TemplateBinding ItemTemplateSelector}" IsHitTestVisible="False"/> <TextBox Visibility="Hidden" Template="{DynamicResource ComboBoxTextBox}" HorizontalAlignment="Left" Margin="3,3,23,3" x:Name="PART_EditableTextBox" Style="{x:Null}" VerticalAlignment="Center" Focusable="True" Background="Transparent" IsReadOnly="{TemplateBinding IsReadOnly}"/> <Popup IsOpen="{TemplateBinding IsDropDownOpen}" Placement="Bottom" x:Name="Popup" Focusable="False" AllowsTransparency="True" PopupAnimation="Slide"> <Grid MaxHeight="{TemplateBinding MaxDropDownHeight}" MinWidth="{TemplateBinding ActualWidth}" x:Name="DropDown" SnapsToDevicePixels="True"> <Border x:Name="DropDownBorder" Background="{DynamicResource ShadeBrush}" BorderBrush="{DynamicResource SolidBorderBrush}" BorderThickness="1"/> <ScrollViewer Margin="4,6,4,6" SnapsToDevicePixels="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" CanContentScroll="True"> <StackPanel IsItemsHost="True" KeyboardNavigation.DirectionalNavigation="Contained"/> </ScrollViewer> </Grid> </Popup> </Grid> <ControlTemplate.Triggers> **<Trigger Property="IsMouseOver" Value="True"> <Setter Property="IsOpen" Value="True" TargetName="Popup"/> </Trigger>** </ControlTemplate.Triggers> </ControlTemplate> But nothing happens with this code. So I trid the following Event trigger in ControlTemplate.Triggers <EventTrigger RoutedEvent="UIElement.GotFocus"> <BeginStoryboard> <Storyboard > <BooleanAnimationUsingKeyFrames Storyboard.TargetName="Popup" Storyboard.TargetProperty="IsOpen" FillBehavior="HoldEnd"> <DiscreteBooleanKeyFrame KeyTime="00:00:00" Value="True" /> </BooleanAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="UIElement.LostFocus"> <BeginStoryboard> <Storyboard > <BooleanAnimationUsingKeyFrames Storyboard.TargetName="Popup" Storyboard.TargetProperty="IsOpen" FillBehavior="HoldEnd"> <DiscreteBooleanKeyFrame KeyTime="00:00:00" Value="False" /> </BooleanAnimationUsingKeyFrames> </Storyboard> </BeginStoryboard> </EventTrigger> Now this helps open the popup on focus, but when I select any item from dropdown the pop up doesnt disappear as usual; it stays open. it closes only after I click somewhere else in the window. Can someone please suggest the proper way to do this Thanks in advance

  • CKEDITOR - Is there anyway to prevent formatting code in SOURCE mode?

    - by Lev
    I've spent the good portion of my day trying to figure this out, and I figured I'd finally just give in and ask. How can you prevent ANY automatic formatting when in SOURCE mode? I like to edit HTML source code directly instead of using the WYSIWYG interface, but whenever I write new lines, or layout tags how I would indent them, it all gets formatted when I switch to WYSIWYG mode and then back to SOURCE mode again. I stumbled upon this earlier: http://dev.fckeditor.net/ticket/993 That alluded to a setting which may have existed once upon a time which would be exactly what I'm after. I just want to know how I can completely turn off all automatic formatting when editing in SOURCE mode. After browsing this site for hours on end and finding absolutely nothing on here or on Google, I came up with a solution I thought would be foolproof (albeit not a pleasant one). I learned about the "protectedSource" setting, so I thought, well maybe I can just use that and create an HTML comment tag before all my HTML and another after it and then push a regular expression finding the comment tags into the protectedSource array, but even that (believe it or not) doesn't work. I've tried my expression straight up in the browser outside of CKEDITOR and it is working, but CKEDITOR doesn't protect the code as expected (which I suspect is a bug involving comment tags, since I can get it to work with other strings). In case you are wondering, this is what I had hoped would work as a work-around, but doesn't: config.protectedSource.push( /<!-- src -->[\s\S]*<!-- end src-->/gi ); .. and what I planned on doing (for what appears to be the lack of a setting to disable formatting in SOURCE mode) was to nest all my HTML within the commented tags like this: <!-- src --> <div>some code that shouldn't be messed with (but is)</div> <!-- end src --> I'd love to hear if you anyone has any suggestions for this scenario, or knows of a setting which I have described, or even if someone can just fill me in as to why I can't get protectedSource to work properly with two comment tags. I really thing it's gotta be a bug because I can get so many other expressions to work fine, and I can even protect HTML within the area of a single comment tag, but I simply cannot get HTML within two different comment tags to stay untouched. :( I've wasted about 6-7 hours on this so far today so if anyone can shed any light on it I would be very grateful! Thanks for reading! ;)

  • How do I reward my developers for the little things they get right?

    - by Nat
    I am in a tech lead role and my developers get stuff right most of the time. How do I communicate to them thier value to me? (I.e. they have value because I do not have to go through and point out mistakes which means I do not have to watch them like a hawk which frees me to do more useful things). In summary For doing the mundane well on a day to day basis, it is good to recognise the developers effort verbally to them. An honest thankyou that mentions the specific behaviour and its positive repercussions to you personally will be well received, adjust the language to suite each individual. (Note that other developers within earshot may also respond to this by increasing their efforts in this specific activity.) Other things that should be done regularly are: Team drinks In many cultures this is an entirely worthy way of giving the team some time to socialise and relax. Be sure that you do not exclude people who do not drink or are not keen on pub culture. Shared meals are another option. Formal written (email) acknowledgment and praise to senior managers of the teams efforts and successes. (Note that acknowledging individuals alone may damage team spirit) Work the hours you expect your team to do. If they absolutely must work late for a deadline, be there in support Go to bat for the team. Refuse to let them be forced to work long periods of overtime without compensation. Protect them from level politics and stress. Give your team the best equipment you can afford. Good tools show respect and improve productivity. Small or large team rewards where appropriate can consist of many interesting activities/ items. If it allows the team to get together in a fun and even lightly competitive manner it will work (foosball table, go-karting, darts board, video game console etc). Don’t forget to listen to what the team wants, each team will have different ideas. Ensure they are getting a fair deal financially from the company. While different people may have different expectations of their pay, someone being paid unfairly will rot morale for the entire team

  • How to integrate Purify into Hudson CI?

    - by Martin
    Hello everybody! I have a Hudson CI system set up and for the moment it is used for building a project and running some unit tests. My next step is to integrate the memory leak detector Purify into the build cycle. Now I want to start the unit tests also inside purify and for this I have created a new batch task which runs following command: purify.exe /SaveTextData MyExecutable.exe --test TestLibrary.dll --output xml As I read in the Purify documentation the /SaveTextData option is used in order to run purify not in GUI mode. If I run this command on my local workstation in the command line it works perfectly. But in case it is started by Hudson, nothing happens. Unfortunetly there are no logs of purify... Has someone ever tried to start purify either by Hudson or any other CI system? Thanks in advance. Best regards Martin EDIT: I forgot to tell you, that I have Hudson running as master and slave on different computers. On the master I have configured a task which should start the unit tests within purify on the slave. I am running the slave via JNLP. EDIT 18.03.2010: Ok, so finally I am a bit closer the source of the problem. I have discovered, that running my unit tests in purify locally the log file EngineCmdLine.log contains three commands. I am starting purify with following command: purify.exe /SaveTextData TestRunnerConsoleWD.exe --test TestDemoWD.dll Output of EngineCmdLine.log when starting purify manually: File: D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestRunnerConsoleWD.exe File: C:\WINDOWS\system32\ws2_32.dll File: D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestDemoWD.dll Output when starting via Hudson: File: D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestRunnerConsoleWD.exe File: C:\WINDOWS\system32\ws2_32.dll File: D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestDemoWD.dll File: D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestDemoWD.dll The error output of purify: Instrumenting: BtcTestDemoWD.dll 313856 bytes Purify: While processing file D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TESTFWWD.DLL: Error: Cannot replace file c:\Programme\IBM\RationalPurifyPlus\PurifyPlus\cache\BTCTESTFWWD$Purify_D_workspace_hudson_workspace_Purify_TestFW_CommonsCoreTest_Cpp_msvs9.DLL.

TESTFWWD.DLL 505344 bytes Unable to instrument D:\workspace\hudson\workspace\Purify_TestFW_CommonsCoreTest_Cpp_msvs9\TestDemoWD.dll (0x1) Question is, why is purify starting twice a command with the TestDemoWD.dll library?

  • Fragment not showing up and breaks other buttons on Layout

    - by Devin Crane
    I'm learning how to use Fragments, and trying to add a fragment tag_button.xml at runtime to a FrameLayout tagFragmentContainer deep within another layout, deepLayout.xml. I get no errors, but the fragment doesn't show up. When I make its container visible, I can see a small sliver of layout between the other elements already existing, but then it disappears after onCreateView(), and all the remaining buttons are broken, which is even more confusing to me. tag_button.xml is just a regular layout file with some text and a button. tagFragmentContainer, within a LinearLayout in the middle of a large layout file, deepLayout.xml: <LinearLayout android:id="@+id/tagButtonsLayout" android:layout_marginBottom="10dip" android:visibility="gone" style="@style/Form"> <FrameLayout android:id="@+id/tagFragmentContainer" android:layout_marginBottom="10dip" style="@style/Form"> </FrameLayout> </LinearLayout> In deepLayoutActivity, I make visible tagButtonsLayout and start TagButtonActivity: final LinearLayout anotherlm = (LinearLayout) findViewById(R.id.tagButtonsLayout); anotherlm.setVisibility(View.VISIBLE); Intent i = new Intent (this, TagButtonActivity.class); startActivity(i); TagButtonActivity is as follows: public class TagButtonActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.action_expense); if (savedInstanceState != null) return; TagButtonFragment firstFragment = new TagButtonFragment(); getSupportFragmentManager().beginTransaction().add(R.id.tagFragmentContainer, firstFragment, "tagOne").commit(); } } TagButtonFragment: public class TagButtonFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.tag_button, container, false); } } tag_button.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" style="@style/Form"> <TextView android:id="@+id/tag_button_header" style="@style/FieldHeader" android:text="example text"/> <RelativeLayout android:id="@+id/tag_button_block" android:layout_width="match_parent" android:layout_marginLeft="2dip" android:layout_marginTop="3dip" android:layout_marginBottom="3dip" android:layout_marginRight="2dip" android:layout_height="43dip" android:clickable="true" android:background="@drawable/row_spinner_selector"> <ImageView android:id="@+id/question_arrow" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dip" android:layout_marginRight="10dip" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:src="@drawable/arrow_right"/> <TextView android:id="@+id/tag_question_text" android:layout_toLeftOf="@id/question_arrow" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="10dip" android:layout_centerVertical="true" android:textColor="@android:color/black" android:singleLine="true" android:ellipsize="end" android:textSize="15sp" android:text="@string/not_selected"/> </RelativeLayout> </LinearLayout> I would certainly appreciate any help in figuring this out from someone who knows fragments better than me! Thanks!

  • Unable to capture standard output of process using Boost.Process

    - by Chris Kaminski
    Currently am using Boost.Process from the Boost sandbox, and am having issues getting it to capture my standard output properly; wondering if someone can give me a second pair of eyeballs into what I might be doing wrong. I'm trying to take thumbnails out of RAW camera images using DCRAW (latest version), and capture them for conversion to QT QImage's. The process launch function: namespace bf = ::boost::filesystem; namespace bp = ::boost::process; QImage DCRawInterface::convertRawImage(string path) { // commandline: dcraw -e -c <srcfile> -> piped to stdout. if ( bf::exists( path ) ) { std::string exec = "bin\\dcraw.exe"; std::vector<std::string> args; args.push_back("-v"); args.push_back("-c"); args.push_back("-e"); args.push_back(path); bp::context ctx; ctx.stdout_behavior = bp::capture_stream(); bp::child c = bp::launch(exec, args, ctx); bp::pistream &is = c.get_stdout(); ofstream output("C:\\temp\\testcfk.jpg"); streamcopy(is, output); } return (NULL); } inline void streamcopy(std::istream& input, std::ostream& out) { char buffer[4096]; int i = 0; while (!input.eof() ) { memset(buffer, 0, sizeof(buffer)); int bytes = input.readsome(buffer, sizeof buffer); out.write(buffer, bytes); i++; } } Invoking the converter: DCRawInterface DcRaw; DcRaw.convertRawImage("test/CFK_2439.NEF"); The goal is to simply verify that I can copy the input stream to an output file. Currently, if I comment out the following line: args.push_back("-c"); then the thumbnail is written by DCRAW to the source directory with a name of CFK_2439.thumb.jpg, which proves to me that the process is getting invoked with the right arguments. What's not happening is connecting to the output pipe properly. FWIW: I'm performing this test on Windows XP under Eclipse 3.5/Latest MingW (GCC 4.4).

  • Beautifulsoup recursive attribute

    - by Marcos Placona
    Hi, trying to parse an XML with Beautifulsoup, but hit a brick wall when trying to use the "recursive" attribute with findall() I have a pretty odd xml format shown below: <?xml version="1.0"?> <catalog> <book id="bk101"> <author>Gambardella, Matthew</author> <title>XML Developer's Guide</title> <genre>Computer</genre> <price>44.95</price> <publish_date>2000-10-01</publish_date> <description>An in-depth look at creating applications with XML.</description> <catalog>true</catalog> </book> <book id="bk102"> <author>Ralls, Kim</author> <title>Midnight Rain</title> <genre>Fantasy</genre> <price>5.95</price> <publish_date>2000-12-16</publish_date> <description>A former architect battles corporate zombies, an evil sorceress, and her own childhood to become queen of the world.</description> <catalog>false</catalog> </book> </catalog> As you can see, the catalog tag repeats inside the book tag, which causes an error when I try to to something like: from BeautifulSoup import BeautifulStoneSoup as BSS catalog = "catalog.xml" def open_rss(): f = open(catalog, 'r') return f.read() def rss_parser(): rss_contents = open_rss() soup = BSS(rss_contents) items = soup.findAll('catalog', recursive=False) for item in items: print item.title.string rss_parser() As you will see, on my soup.findAll I've added recursive=false, which in theory would make it no recurse through the item found, but skip to the next one. This doesn't seem to work, as I always get the following error: File "catalog.py", line 17, in rss_parser print item.title.string AttributeError: 'NoneType' object has no attribute 'string' I'm sure I'm doing something stupid here, and would appreciate if someone could give me some help on how to solve this problem. Changing the HTML structure is not an option, this this code needs to perform well as it will potentially parse a large XML file. Thanks in advance, Marcos

  • Scipy Negative Distance? What?

    - by disappearedng
    I have a input file which are all floating point numbers to 4 decimal place. i.e. 13359 0.0000 0.0000 0.0001 0.0001 0.0002` 0.0003 0.0007 ... (the first is the id). My class uses the loadVectorsFromFile method which multiplies it by 10000 and then int() these numbers. On top of that, I also loop through each vector to ensure that there are no negative values inside. However, when I perform _hclustering, I am continually seeing the error, "Linkage Z contains negative values". I seriously think this is a bug because: I checked my values, the values are no where small enough or big enough to approach the limits of the floating point numbers and the formula that I used to derive the values in the file uses absolute value (my input is DEFINITELY right). Can someone enligten me as to why I am seeing this weird error? What is going on that is causing this negative distance error? ===== def loadVectorsFromFile(self, limit, loc, assertAllPositive=True, inflate=True): """Inflate to prevent "negative" distance, we use 4 decimal points, so *10000 """ vectors = {} self.winfo("Each vector is set to have %d limit in length" % limit) with open( loc ) as inf: for line in filter(None, inf.read().split('\n')): l = line.split('\t') if limit: scores = map(float, l[1:limit+1]) else: scores = map(float, l[1:]) if inflate: vectors[ l[0]] = map( lambda x: int(x*10000), scores) #int might save space else: vectors[ l[0]] = scores if assertAllPositive: #Assert that it has no negative value for dirID, l in vectors.iteritems(): if reduce(operator.or_, map( lambda x: x < 0, l)): self.werror( "Vector %s has negative values!" % dirID) return vectors def main( self, inputDir, outputDir, limit=0, inFname="data.vectors.all", mappingFname='all.id.features.group.intermediate'): """ Loads vector from a file and start clustering INPUT vectors is { featureID: tfidfVector (list), } """ IDFeatureDic = loadIdFeatureGroupDicFromIntermediate( pjoin(self.configDir, mappingFname)) if not os.path.exists(outputDir): os.makedirs(outputDir) vectors = self.loadVectorsFromFile( limit, pjoin( inputDir, inFname)) for threshold in map( lambda x:float(x)/30, range(20,30)): clusters = self._hclustering(threshold, vectors) if clusters: outputLoc = pjoin(outputDir, "threshold.%s.result" % str(threshold)) with open(outputLoc, 'w') as outf: for clusterNo, cluster in clusters.iteritems(): outf.write('%s\n' % str(clusterNo)) for featureID in cluster: feature, group = IDFeatureDic[featureID] outline = "%s\t%s\n" % (feature, group) outf.write(outline.encode('utf-8')) outf.write("\n") else: continue def _hclustering(self, threshold, vectors): """function which you should call to vary the threshold vectors: { featureID: [ tfidf scores, tfidf score, .. ] """ clusters = defaultdict(list) if len(vectors) > 1: try: results = hierarchy.fclusterdata( vectors.values(), threshold, metric='cosine') except ValueError, e: self.werror("_hclustering: %s" % str(e)) return False for i, featureID in enumerate( vectors.keys()):

  • NoSQL DB for .Net document-based database (ECM)

    - by Dane
    I'm halfway through coding a basic multi-tenant SaaS ECM solution. Each client has it's own instance of the database / datastore, but the .Net app is single instance. The documents are pretty much read only (i.e. an image archive of tiffs or PDFs) I've used MSSQL so far, but then started thinking this might be viable in a NoSQL DB (e.g. MongoDB, CouchDB). The basic premise is that it stores documents, each with their own particular indexes. Each tenant can have multiple document types. e.g. One tenant might have an invoice type, which has Customer ID, Invoice Number and Invoice Date. Another tenant might have an application form, which has Member Number, Application Number, Member Name, and Application Date. So far I've used the old method which Sharepoint (used?) to use, and created a document table which has int_field_1, int_field_2, date_field_1, date_field_2, etc. Then, I've got a "mapping" table which stores the customer specific index name, and the database field that will map to. I've avoided the key-value pair model in the DB due to volume of documents. This way, we can support multiple document types in the one table, and get reasonably high performance out of it, and allow for custom document type searches (i.e. user selects a document type, then they're presented with a list of search fields). However, a NoSQL DB might make this a lot simpler, as I don't need to worry about denormalizing the document. However, I've just got concerns about the rest of the data around a document. We store an "action history" against the document. This tracks views, whether someone emails the document from within the system, and other "future" functionality (e.g. faxing). We have control over the document load process, so we can manipulate the data however it needs to be to get it in the document store (e.g. assign unique IDs). Users will not be adding in their own documents, so we shouldn't need to worry about ACID compliance, as the documents are relatively static. So, my questions I guess : Is a NoSQL DB a good fit Is MongoDB the best for Asp.Net (I saw Raven and Velocity, but they're still kinda beta) Can I store a key for each document, and then store the action history in a MSSQL DB with this key? I don't need to do joins, it would be if a person clicks "View History" against a document. How would performance compare between the two (NoSQL DB vs denormalized "document" table) Volumes would be up to 200,000 new documents per month for a single tenant. My current scaling plan with the SQL DB involves moving the SQL DB into a cluster when certain thresholds are reached, and then reviewing partitioning and indexing structures.

  • What was your the most impressive technical programming achievement performed to impress a romantic

    - by DVK
    OK, so the archetypal human story is for a guy to go out and impress the girl with some wonderful achievement like slaying a dragon or building a monument or conquering neighboring tribe. This being enlightened 21st century on SO, let's morph this into a: StackOverflower performing a feat of programming to impress a romantic interest. There are two ways to do this: Technical achievement: Impressing a person with suitable background/understanding of programming with actual coding powerss you displayed. A dumb movie example would be that kid in "Hackers" move showing off his hacking skills in front of Angeline Jolie. Artistic achievement: Impressing a person with a result of running said code, whether they understand just how incredible the code itself is. An example is the animated ANSI rose (for a guy who actually wrote the ANSI code) This question is only about the first kind (technical achievements) - e.g. the person of interest was presented with impressive code/design that (s)he was able to properly appreciate. Rules (what doesn't qualify): The target audience must have been a person of romantic interest (prospective or present significant other or random hook-up). E.g. showing your program to your sister who's also a software developer doesn't count. The achievement must have been done specifically with the goal to impress such a person. However, it is OK if the achievement was done to impress a generic qualifying person, not someone specific. Although... if you write code to impress girls in general, I'd say "get a better idea of the opposite sex" The achievement must have been done with the goal of impressing the person. In other words, if you would have done it without romantic interest's knowledge anyway, it doesn't count. As examples, the following does not count: programming for your job. Programming for a coding contest. Open Source program that you'd have done anyway. The precise nature of the awesomeness of the achievement is somewhat irrelevant - from learning entire J2EE in 2 days to writing fancy game engine to implementing Python compiler in LOGO. As long as it's programming/software development related. The achievement should preferably be something other people would rank highly as well. If your date was impressed with your skill at calculating Fibonacci sequence without recursive function calls, it doesn't mean most developers will be. But it does mean you need to start finding better things to do on dates ;)

  • $.ajax post to PHP mail() using jQuery doesn't work

  • How to efficiently save changes made in UI/main thread with Core Data?

    - by Jaanus
    So, there have been several posts here about importing and saving data from an external data source into Core Data. Apple documents a reasonable pattern for this: "import and save on background thread, merge saved objects to main thread." All fine and good. I have a related but different problem: the user is modifying data in the UI and main thread, and thus modifies state of some objects in the managed object context (MOC). I would like to save these changes from time to time. What is a good way to do that? Now, you could say that I could do the same: create a background thread with its own MOC and pass the changed objectID-s there. The catch-22 for me with this is that an object's ID changes when it is saved, and I cannot guarantee the order of things happening. I may end up passing a different objectID into the background thread for the same object, based on whether the object has been previously saved or not, and I don't know if Core Data can resolve this and see that different objectID-s are pointing to the same object and not create duplicates for me. (I could test this, but I'm lazywebbing with this question first.) One thought I had: I could always do MOC saves on a background thread, and queue them up with operationqueue, so that there is always only one save in progress. I would not create a new MOC, I would just use the same MOC as in main thread. Now, this is not thread safe and when someone modifies the MOC in main thread while it is being saved in background thread, the results will probably be catastrophic. But, minus the thread safety, you can see what kind of solution I'd wish for. To be clear, the problem I need to fix is that if I just do the save in main thread, it blocks the UI for an unacceptably long period of time, I want to move the save to background thread. So, questions: what about the reasoning of an object ID changing during saving, and Core Data being able to resolve them to the same object? Would this be the right way of addressing this problem? any other good ways of doing this?

  • Problem connecting to postgres with Kohana 3 database module on OS X Snow Leopard

    Environment: Mac OS X 10.6 Snow Leopard PHP 5.3 Kohana 3.0.4 When I try to configure and use a connection to a postgresql database on localhost I get the following error: ErrorException [ Warning ]: mysql_connect(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) Here is the configuration of the database in /modules/database/config/database.php (note the third instance named 'pgsqltest') return array ( 'default' => array ( 'type' => 'mysql', 'connection' => array( /** * The following options are available for MySQL: * * string hostname * string username * string password * boolean persistent * string database * * Ports and sockets may be appended to the hostname. */ 'hostname' => 'localhost', 'username' => FALSE, 'password' => FALSE, 'persistent' => FALSE, 'database' => 'kohana', ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), 'alternate' => array( 'type' => 'pdo', 'connection' => array( /** * The following options are available for PDO: * * string dsn * string username * string password * boolean persistent * string identifier */ 'dsn' => 'mysql:host=localhost;dbname=kohana', 'username' => 'root', 'password' => 'r00tdb', 'persistent' => FALSE, ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), 'pgsqltest' => array( 'type' => 'pdo', 'connection' => array( /** * The following options are available for PDO: * * string dsn * string username * string password * boolean persistent * string identifier */ 'dsn' => 'mysql:host=localhost;dbname=pgsqltest', 'username' => 'postgres', 'password' => 'dev1234', 'persistent' => FALSE, ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), ); And here is the code to create the database instance, create a query and execute the query: $pgsqltest_db = Database::instance('pgsqltest'); $query = DB::query(Database::SELECT, 'SELECT * FROM test')->execute(); I'm continuing to research a solution for this error but thought I'd ask to see if someone else has already found a solution.

  • wxPython ListCtrl Column Ignores Specific Fields

    - by g.d.d.c
    I'm rewriting this post to clarify some things and provide a full class definition for the Virtual List I'm having trouble with. The class is defined like so: from wx import ListCtrl, LC_REPORT, LC_VIRTUAL, LC_HRULES, LC_VRULES, \ EVT_LIST_COL_CLICK, EVT_LIST_CACHE_HINT, EVT_LIST_COL_RIGHT_CLICK, \ ImageList, IMAGE_LIST_SMALL, Menu, MenuItem, NewId, ITEM_CHECK, Frame, \ EVT_MENU class VirtualList(ListCtrl): def __init__(self, parent, datasource = None, style = LC_REPORT | LC_VIRTUAL | LC_HRULES | LC_VRULES): ListCtrl.__init__(self, parent, style = style) self.columns = [] self.il = ImageList(16, 16) self.Bind(EVT_LIST_CACHE_HINT, self.CheckCache) self.Bind(EVT_LIST_COL_CLICK, self.OnSort) if datasource is not None: self.datasource = datasource self.Bind(EVT_LIST_COL_RIGHT_CLICK, self.ShowAvailableColumns) self.datasource.list = self self.Populate() def SetDatasource(self, datasource): self.datasource = datasource def CheckCache(self, event): self.datasource.UpdateCache(event.GetCacheFrom(), event.GetCacheTo()) def OnGetItemText(self, item, col): return self.datasource.GetItem(item, self.columns[col]) def OnGetItemImage(self, item): return self.datasource.GetImg(item) def OnSort(self, event): self.datasource.SortByColumn(self.columns[event.Column]) self.Refresh() def UpdateCount(self): self.SetItemCount(self.datasource.GetCount()) def Populate(self): self.UpdateCount() self.datasource.MakeImgList(self.il) self.SetImageList(self.il, IMAGE_LIST_SMALL) self.ShowColumns() def ShowColumns(self): for col, (text, visible) in enumerate(self.datasource.GetColumnHeaders()): if visible: self.columns.append(text) self.InsertColumn(col, text, width = -2) def Filter(self, filter): self.datasource.Filter(filter) self.UpdateCount() self.Refresh() def ShowAvailableColumns(self, evt): colMenu = Menu() self.id2item = {} for idx, (text, visible) in enumerate(self.datasource.columns): id = NewId() self.id2item[id] = (idx, visible, text) item = MenuItem(colMenu, id, text, kind = ITEM_CHECK) colMenu.AppendItem(item) EVT_MENU(colMenu, id, self.ColumnToggle) item.Check(visible) Frame(self, -1).PopupMenu(colMenu) colMenu.Destroy() def ColumnToggle(self, evt): toggled = self.id2item[evt.GetId()] if toggled[1]: idx = self.columns.index(toggled[2]) self.datasource.columns[toggled[0]] = (self.datasource.columns[toggled[0]][0], False) self.DeleteColumn(idx) self.columns.pop(idx) else: self.datasource.columns[toggled[0]] = (self.datasource.columns[toggled[0]][0], True) idx = self.datasource.GetColumnHeaders().index((toggled[2], True)) self.columns.insert(idx, toggled[2]) self.InsertColumn(idx, toggled[2], width = -2) self.datasource.SaveColumns() I've added functions that allow for Column Toggling which facilitate my description of the issue I'm encountering. On the 3rd instance of this class in my application the Column at Index 1 will not display String values. Integer values are displayed properly. If I add print statements to my OnGetItemText method the values show up in my console properly. This behavior is not present in the first two instances of this class, and my class does not contain any type checking code with respect to value display. It was suggested by someone on the wxPython users' group that I create a standalone sample that demonstrates this issue if I can. I'm working on that, but have not yet had time to create a sample that does not rely on database access. Any suggestions or advice would be most appreciated. I'm tearing my hair out on this one.

  • Trouble cross-referencing two XML child nodes in AS3

    - by Dwayne
    I am building a mini language translator out of XML nodes and Actionscript 3. I have my XML ready. It contains a series of nodes with two children in them. Here is a sample: <translations> <entry> <english>man</english> <cockney>geeza</cockney> </entry> <entry> <english>woman</english> <cockney>lily</cockney> </entry> </translations> The AS3 part consist of one input box named "textfield_txt" where the English word will be typed in. An output text field for the translation called "cockney_txt". Finally, one button to execute the translation called "generate_mc". The idea is to have actionscript look through the XML for key English words after the user types it in the "textfield", cross-freferences the children then returns the Cockney translation as a value. The trouble is, when I test it I get no response or error messages- it's completely silent. I'm not sure what I'm doing wrong. At present, I have setup a conditional statement to tell me whether the function works or not. The result is, no it's not! Here's the code below. I hope someone can help. Cheers! generate_mc.buttonMode=true; var English:String; var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("Language.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); function processXML(e:Event):void { myXML = new XML(e.target.data); } generate_mc.addEventListener(MouseEvent.CLICK, onClick); function onClick(event:MouseEvent) { English = textfield.text; cockney_txt.text = myXML.translations.entry.cockney; if(textfield.text.toLowerCase() == myXML.translations.entry.english.toLowerCase){ //return myXML.translations.entry.cockney; trace("success"); }else{ trace("try again!"); // ***I get this as a result } }

  • Controling virtualbox internet access?

    - by HandyGandy
    I am finally going through the process of moving my XP into a vbox (host linux). The thing is that I am migrating a virtually clean install. So aside from the occasional antivirus scan, I want to make sure that my XP is not sending malware data (keystoke.logs, spam etc. ) out silently ( and thus having picked up some virus ). To that end I want to limit XP to contacting my LAN and a few internet sites. ( mainly sites that require proprietary windows only software to access, AV sites and Windows update ). I want XP to only access preapproved addresses. If it is trying to contact a nonapproved address, I want it somehow logged and access restricted until I allow access. I also don't want to have to decide whether to allow access to a site at my leisure. To keeps things clear let me give an example: I start my vbox/XP ( which I call MYXP) running on my linux box ( called MYLINUX connecting to the net through a linksys wrt54g ) and connects via samba to my LAN ( since my LAN seems to be possessed of every evil thing, it's address is 192.168.666. ). At the moment my configuration is set so that I allow MYXP to access 192.168.666 and www.MYANTIVIRUS_UPDATES.com and www.MS_UPDATES.com. Then on the VM I start a program which tries to make a connection to www.playmygame.com . www.playmygame.com is on my preapproved list so the connection goes through. Later I check attempted accesses and discover that it also tried to connect to www.mygame_high_scores.com I figure this is OK so I add www.mygame_high_scores.com to my approved list. Later, I again check address and discover that my VM/XP tried to access www.mygame_steals_your_identity.com. I do some checking and discover the address is registered to someone in Kiev, Nigeria. Since this doesn't sound kosher to me, I replace the MYXP VM with one that was backed up before I installed mygame. I remove www.playmygame.com and www.mygame_high_scores.com from my access list for MYXP. It should acomplish this with little overheard. When I am not running the VM ideally it should not have any overhead. Suggestions?

  • Need help with implementation of the jQuery LiveUpdate routine

    - by miCRoSCoPiC_eaRthLinG
    Hey all, Has anyone worked with the LiveUpdate function (may be a bit of a misnomer) found on this page? It's not really a live search/update function, but a quick filtering mechanism for a pre-existing list, based on the pattern you enter in a text field. For easier reference, I'm pasting the entire function in here: jQuery.fn.liveUpdate = function(list){ list = jQuery(list); if ( list.length ) { var rows = list.children('li'), cache = rows.map(function(){ return this.innerHTML.toLowerCase(); }); this .keyup(filter).keyup() .parents('form').submit(function(){ return false; }); } return this; function filter(){ var term = jQuery.trim( jQuery(this).val().toLowerCase() ), scores = []; if ( !term ) { rows.show(); } else { rows.hide(); cache.each(function(i){ var score = this.score(term); if (score > 0) { scores.push([score, i]); } }); jQuery.each(scores.sort(function(a, b){return b[0] - a[0];}), function(){ jQuery(rows[ this[1] ]).show(); }); } } }; I have this list, with members as the ID. And a text field with say, qs as ID. I tried binding the function in the following manner: $( '#qs' ).liveUpdate( '#members' ); But when I do this, the function is called only ONCE when the page is loaded (I put in some console.logs in the function) but never after when text is keyed into the text field. I also tried calling the routine from the keyup() function of qs. $( '#qs' ).keyup( function() { $( this ).liveUpdate( '#members' ); }); This ends up going into infinite loops (almost) and halting with "Too much recursion" errors. So can anyone please shed some light on how I am supposed to actually implement this function? Also while you are at it, can someone kindly explain this line to me: var score = this.score(term); What I want to know is where this member method score() is coming from? I didn't find any such method built into JS or jQuery. Thanks for all the help, m^e

  • MBR Booting from DOS

  • Event Listener in Google Charts API

    - by DeanGrobler
    I'm busy using Google Charts in one of my projects to display data in a table. Everything is working great. Except that I need to see what line a user selected once they click a button. This would obviously be done with Javascript, but I've been struggling for days now to no avail. Below I've pasted code for a simple example of the table, and the Javascript function that I want to use (that doesn't work). <html> <head> <script type='text/javascript' src='https://www.google.com/jsapi'></script> <script type='text/javascript'> google.load('visualization', '1', {packages:['table']}); google.setOnLoadCallback(drawTable); var table = ""; function drawTable() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Name'); data.addColumn('number', 'Salary'); data.addColumn('boolean', 'Full Time Employee'); data.addRows(4); data.setCell(0, 0, 'Mike'); data.setCell(0, 1, 10000, '$10,000'); data.setCell(0, 2, true); data.setCell(1, 0, 'Jim'); data.setCell(1, 1, 8000, '$8,000'); data.setCell(1, 2, false); data.setCell(2, 0, 'Alice'); data.setCell(2, 1, 12500, '$12,500'); data.setCell(2, 2, true); data.setCell(3, 0, 'Bob'); data.setCell(3, 1, 7000, '$7,000'); data.setCell(3, 2, true); table = new google.visualization.Table(document.getElementById('table_div')); table.draw(data, {showRowNumber: true}); } function selectionHandler() { selectedData = table.getSelection(); row = selectedData[0].row; item = table.getValue(row,0); alert("You selected :" + item); } </script> </head> <body> <div id='table_div'></div> <input type="button" value="Select" onClick="selectionHandler()"> </body> </html> Thanks in advance for anyone taking the time to look at this.

  • How can I turn a string of text into a BigInteger representation for use in an El Gamal cryptosystem

    - by angstrom91
    I'm playing with the El Gamal cryptosystem, and my goal is to be able to encipher and decipher long sequences of text. I have come up with a method that works for short sequences, but does not work for long sequences, and I cannot figure out why. El Gamal requires the plaintext to be an integer. I have turned my string into a byte[] using the .getBytes() method for Strings, and then created a BigInteger out of the byte[]. After encryption/decryption, I turn the BigInteger into a byte[] using the .toByteArray() method for BigIntegers, and then create a new String object from the byte[]. This works perfectly when i call ElGamalEncipher with strings up to 129 characters. With 130 or more characters, the output produced is garbled. Can someone suggest how to solve this issue? Is this an issue with my method of turning the string into a BigInteger? If so, is there a better way to turn my string of text into a BigInteger and back? Below is my encipher/decipher code. public static BigInteger[] ElGamalEncipher(String plaintext, BigInteger p, BigInteger g, BigInteger r) { // returns a BigInteger[] cipherText // cipherText[0] is c // cipherText[1] is d BigInteger[] cipherText = new BigInteger[2]; BigInteger pText = new BigInteger(plaintext.getBytes()); // 1: select a random integer k such that 1 <= k <= p-2 BigInteger k = new BigInteger(p.bitLength() - 2, sr); // 2: Compute c = g^k(mod p) BigInteger c = g.modPow(k, p); // 3: Compute d= P*r^k = P(g^a)^k(mod p) BigInteger d = pText.multiply(r.modPow(k, p)).mod(p); // C =(c,d) is the ciphertext cipherText[0] = c; cipherText[1] = d; return cipherText; } public static String ElGamalDecipher(BigInteger c, BigInteger d, BigInteger a, BigInteger p) { //returns the plaintext enciphered as (c,d) // 1: use the private key a to compute the least non-negative residue // of an inverse of (c^a)' (mod p) BigInteger z = c.modPow(a, p).modInverse(p); BigInteger P = z.multiply(d).mod(p); byte[] plainTextArray = P.toByteArray(); String output = null; try { output = new String(plainTextArray, "UTF8"); } catch (Exception e) { } return output; }

But when we move to higher envs the team that deploys this application does it successfully initially but after a few restarts of the application the entitymanager starts giving this problem Caused by: javax.persistence.PersistenceException: [PersistenceUnit: ConfigAPPPersist] Unable to build EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:677) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:132) at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:224) at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:291) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1368) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1334) ... 32 more Caused by: org.hibernate.MappingException: **property mapping has wrong number of columns**: com.***.***.jpa.marketing.entity.MarketBrands.$performasure_j2eeInfo type: object Now you would say this is pretty obvious the entity MarketBrands is incorrect. But its not it maps to the table just fine. And the same code works on DEV. Also the jndi cannot be incorrect since it deploys and works fine initially but throws uo this error after a restart. This is weird and not very logical. But if someone has faced this or has any idea on what might be causing this Please!! help The persistence.xml for the persitence unit has very little <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> <persistence-unit name="ConfigAPPPersist"> <!-- commented code --> </persistence-unit> </persistence>
