• bash: assign grep regex results to array

  - by Ryan

  Hello everyone, I am trying to assign a regular expression result to an array inside of a bash script but I am unsure whether that's possible, or if I'm doing it entirely wrong. The below is what I want to happen, however I know my syntax is incorrect: indexes[4]=$(echo b5f1e7bfc2439c621353d1ce0629fb8b | grep -o '[a-f0-9]\{8\}') such that: index[1]=b5f1e7bf index[2]=c2439c62 index[3]=1353d1ce index[4]=0629fb8b Any links, or advice, would be wonderful :)

• How do I share an NSArrayController between two nib files?

  - by Tom Dalling

  I have an array of images, and two nib files. One nib file has a window that displays the images in an NSTableView. The other nib has a window that draws the array of images into an NSView, and also draws a highlight over the images that are selected. The array of images is controlled by an NSArrayController. I'm having trouble getting the two nibs to share the NSArrayController. I would have two separate NSArrayControllers bound to the same content, but I also want both nibs to share the controller's selection; that is, if you select an image in the table window, it also becomes selected in the other window. Is there a standard way to do this?

• Javascript timer in parent window is cancelled on child window close

  - by Tom Carter

  I have a user UserControl on a web page. There is a javascript timer started by the control on the client that causes a web service to be called every few seconds. If the user clicks on the control a new browser window is opened (with window.open() ) to show a different page. Note the onclick returns false so there is no postback to the page. The page displayed in the second window also has a timer that operates in the same way as the first (calls a WebService at intervals). Upto this point everything is fine - each of the timers continue to run in their respective window. However, when I close the second window (either by clicking on the cross of the window or by calling self.close() ) the timer in the first stops. I've no idea why. Is there some relationship between the opener and opened window that I'm missing ?

  I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP.

• Select list auto update on any kind of change?

  - by Tom Irons

  I have a jQuery that when you click on a select option it will show the next one, but you have to click, you cant just use the down arrow or "tab" to the next option. I am wondering what options do I have to make this work? Here is my jQuery: function typefunction() { var itemTypes = jQuery('#type'); var select = this.value; itemTypes.change(function () { if ($(this).val() == '1-Hand') { $('.1-Hand').show(); $('.2-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.1-Hand').hide(); if ($(this).val() == '2-Hand') { $('.2-Hand').show(); $('.1-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.2-Hand').hide(); if ($(this).val() == 'Armor') { $('.Armor').show(); $('.2-Hand').hide(); $('.off').hide(); $('.1-Hand').hide(); } else $('.Armor').hide(); if ($(this).val() == 'Off-Hand') { $('.Off').show(); $('.2-Hand').hide(); $('.1-Hand').hide(); $('.Armor').hide(); } else $('.Off').hide(); if ($(this).val() == '1-Hand') { $('.one-hand-dps').show(); $('.item-armor').hide(); $('.two-hand-dps').hide(); } else $('.one-hand-dps').hide(); if ($(this).val() == '2-Hand') { $('.two-hand-dps').show(); $('.one-hand-dps').hide(); $('.item-armor').hide(); } else $('.two-hand-dps').hide(); if ($(this).val() == 'Armor') { $('.item-armor').show(); $('.one-hand-dps').hide(); $('.two-hand-dps').hide(); } else $('.item-armor').hide(); }); } And the HTML: <div class="input-group item"> <span class="input-group-addon">Type</span> <select id="type" name="type" class="form-control" onclick="typefunction(); itemstats(); Armor(); OffHand(); TwoHand();"> <option value="Any Type">Any Type</option> <option value="1-Hand">1-Hand</option> <option value="2-Hand">2-Hand</option> <option value="Armor">Armor</option> <option value="Off-Hand">Off-Hand</option> </select> </div> <div class="input-group item"> <span class="1-Hand input-group-addon" style="display: none;">Sub-Type</span> <select class="1-Hand form-control" name="sub[1]" style="display: none;"> <option value="All 1-Hand Item Types">All 1-Hand Item Types</option> <option>Axe</option> <option>Ceremonial Knife</option> <option>Hand Crossbow</option> <option>Dagger</option> <option>Fist Weapon</option> <option>Mace</option> <option>Mighty Weapon</option> <option>Spear</option> <option>Sword</option> <option>Wand</option> </select> </div> <div class="input-group"> <span class="2-Hand input-group-addon" style="display: none; ">Sub-Type</span> <select class="2-Hand form-control" name="sub[2]" style="display: none;"> <option>All 2-Hand Item Types</option> <option>Two-Handed Axe</option> <option>Bow</option> <option>Diabo</option> <option>Crossbow</option> <option>Two-Handed Mace</option> <option>Two-Handed Mighty Weapon</option> <option>Polearm</option> <option>Staff</option> <option>Two-Handed Sword</option> </select> </div> <div class="input-group"> <span class="Armor input-group-addon" style="display: none;">Sub-Type</span> <select class="Armor form-control" name="sub[3]" style="display:none;"> <option>All Armor Item Types</option> <option>Amulet</option> <option>Belt</option> <option>Boots</option> <option>Bracers</option> <option>Chest Armor</option> <option>Cloak</option> <option>Gloves</option> <option>Helm</option> <option>Pants</option> <option>Mighty Belt</option> <option>Ring</option> <option>Shoulders</option> <option>Spirit Stone</option> <option>Voodoo Mask</option> <option>Wizard Hat</option> </select> </div> <div class="input-group"> <span class="Off input-group-addon" style="display: none;">Sub-Type</span> <select class="Off form-control" name="sub[4]" style="display:none;"> <option>All Off-Hand Item Types</option> <option>Mojo</option> <option>Source</option> <option>Quiver</option> <option>Shield</option> </select> </div>

• javascript replace div tags for p tags where it has no class

  - by Tom

  I would like to replace div tags for p tags but only when the div tag does not have a class. So this: <div class="myDiv"> <div>sdfglkhj sdfgkhl sdfkhgl sdf</div> <div>dsf osdfghjksdfg hsdfg</div> </div> Would become: <div class="myDiv"> <p>sdfglkhj sdfgkhl sdfkhgl sdf</p> <p>dsf osdfghjksdfg hsdfg</p> </div> I've tried .replace("<div>", "<p>").replace("</div>","</p>") but this replaces the closing tag of the one with a class.

• Intercepting hyperlinks in an embedded Word document

  - by Ryan

  Hello, I'm working on an app which uses embedded Word documents. We have a feature which allows them to insert a small clickable image into the doc - when the user clicks on it, we want the app to open another window based on some data specified by the user when the image was added. What the application does now is: When the image is inserted, the app creates a hyperlink for it and the data is used as the link destination The user ctrl+clicks on the image and the Word document the WindowSelectionChange event The app handles the WindowSelectionChange event and goes to open the specified window This approach worked fine with previous versions, when we had the 11.0 / Word 2003 interop dll's. We upgraded to 12.0/Word 2007 for the upcoming release, and in many cases the event is not firing when I click on the image - sometimes it does, sometimes it doesn't, and I'm descending into the cargo-cult world trying to figure out why - sometimes saving and re-opening the document works, sometimes killing the Word process and starting a new one fixes (or breaks) the feature. My guess is there's something going wrong with the WinSelChg event, but I'm not sure what. The usual process we have for applying the event handler is: try //remove the old one if any { ((Document)myAXFramerControl.ActiveDocument).Application.WindowSelectionChange -= new ApplicationEvents4_WindowSelectionChangeEventHandler(WSC_eventhandlerfunction); } catch{} ((Document)myAXFramerControl.ActiveDocument).Application.WindowSelectionChange += new ApplicationEvents4_WindowSelectionChangeEventHandler(WSC_eventhandlerfunction); Sometimes one or both of these will throw exceptions - usually a NullReferenceException when removing the handler. Adding the handler sometimes throws the "com object that has been separated from its underlying rcw cannot be used" exception, which I don't understand at all - my impression was that this only occurs when you, say, store a reference to the Word application or document and try to use it later. As it stands the WSC event handler is frequently never run; while I'm happy to fiddle with the app until it works once I can't really expect the same of the users who have been happily using this feature for a while now. Any ideas?

• What is the point of CSS collapsing margins?

  - by Tom

  The CSS2 box model tells us that adjoining margins collapse. I find it quite annoying, being the source of many design bugs. I hope that by understanding the purpose of collapsing margins, I will understand when to use them and how to avoid them when they are not needed. What is the purpose of this feature?

• Symfony: Weird routing issue

  - by Tom

  Hi, I've got following URL in symfony (specifics not important): /frontend_dev.php/something/25/apple ... and a routing rule: /something/:id/:word The URL works fine when clicked through to on the site, but not when I type in the URL. Instead, symfony says: Unable to find a matching route to generate url for params "NULL". The weird thing is that I can navigate to this page and it works, but when hitting Enter in the browser address bar, it no longer finds it. Any thoughts on what might be the cause of something like this generally? I should also add that the URL was working fine when typed in the address bar earlier, but doesn't anymore, and I'm not sure what's there that might be interfering with it. Thanks in advance.

• Undesired "flashing" in Jquery dropdown menu?

  - by Tom

  Hi, I've got the following piece of Jquery: $("#collapse-menu > li > a").click(function() { $(this).toggleClass("expanded").toggleClass("collapsed").find("+ ul").slideToggle("medium"); }); What it basically does is expands or collapses a menu of nested "lists" which contain dropdowns (simplified example): <ul id="collapse-menu"> <li><a class="expanded">Basic Details</a> <ul> <li> <select> .... </select> </li> <li> <select> .... </select> </li> The code works absolutely fine EXCEPT when a large value is selected in any of the dropdowns. At that point, when clicked, the menu will still expand/collapse correctly but "flash" quickly while doing so, as if the entire element was being reset somehow. The data itself is fine but it's the flashing that's unwanted. The strange thing is that if a small value is selected in a dropdown, there's no flashing. When a large value is selected (say, above 30 in an age dropdown of 18-99), the flashing starts happening. Can anyone tell me why this is happening? Or whether there's something not right about the Jquery that's causing this. Thanks. UPDATE: Adding a bounty to this. Have tried a few similar plugins/solutions out there on the net but they all seem to suffer from this "flashing" problem when large dropdown values are selected by default. If it helps, here's a typical similar solution: http://www.i-marco.nl/weblog/jquery-accordion-menu/index_collapsed.html# ... but it suffers from the same problem when dropdowns are added inside the accordion. I hope someone has a clean solution, instead of needing to hack this somehow.

• Bioperl, equivalent of IO::ScalarArray for array of Seq objects?

  - by Ryan Thompson

  In perl, we have IO::ScalarArray for treating the elements of an array like the lines of a file. In BioPerl, we have Bio::SeqIO, which can produce a filehandle that reads and writes Bio::Seq objects instead of strings representing lines of text. I would like to do a combination of the two: I would like to obtain a handle that reads successive Bio::Seq objects from an array of such objects. Is there any way to do this? Would it be trivial for me to implement a module that does this? My reason for wanting this is that I would like to be able to write a subroutine that accepts either a Bio::SeqIO handle or an array of Bio::Seq objects, and I'd like to avoid writing separate loops based on what kind of input I get. Perhaps the following would be better than writing my own IO module? sub process_sequences { my $input = $_[0]; # read either from array of Bio::Seq or from Bio::SeqIO my $nextseq; if (ref $input eq 'ARRAY') { my $pos = 0 $nextseq = sub { return $input->[$pos++] if $pos < @$input}; } } else { $nextseq = sub { $input->getline(); } } while (my $seq = $nextseq->()) { do_cool_stuff_with($seq) } }

• Rails Heroku Migrate Unknown Error

  - by Ryan Max

  Hello. I am trying to get my app up and running on heroku. However once I go to migrate I get the following error: $ heroku rake db:migrate rake aborted! An error has occurred, this and all later migrations canceled: 530 5.7.0 Must issue a STARTTLS command first. bv42sm676794ibb.5 (See full trace by running task with --trace) (in /disk1/home/slugs/155328_f2d3c00_845e/mnt) == BortMigration: migrating ================================================= -- create_table(:sessions) -> 0.1366s -- add_index(:sessions, :session_id) -> 0.0759s -- add_index(:sessions, :updated_at) -> 0.0393s -- create_table(:open_id_authentication_associations, {:force=>true}) -> 0.0611s -- create_table(:open_id_authentication_nonces, {:force=>true}) -> 0.0298s -- create_table(:users) -> 0.0222s -- add_index(:users, :login, {:unique=>true}) -> 0.0068s -- create_table(:passwords) -> 0.0123s -- create_table(:roles) -> 0.0119s -- create_table(:roles_users, {:id=>false}) -> 0.0029s I'm not sure exactly what it means.

Additionally on Bort the Restful Authentication uses my gmail stmp to send confirmation emails...all the searches on google i do on STARTTLS have to do with stmp. Can someone point me in the right direction?

• PayPal integration woes: PDT hangs on return to site

  - by Tom

  Hi, I'm implementing PayPal IPN & PDT. After some headache & time at the sandbox, IPN is working well and PDT returns the correct $_GET data. The implementation is as follows: Pass user ID in form to PayPal User buys product and triggers IPN which updates database for given user ID PDT returns transaction ID when user returns to site The return page says "please wait" and repeat-Ajax-checks for the transaction status User is redirected to success/failure page Everything works well, EXCEPT that when using the PayPal ready PHP code for PDT to do a return POST, the page hangs. PayPal waits for a response and the user never gets back to my site. I'm not getting a fail status, just nothing. The funny thing is that once the unknown error occurs, my test domain becomes unresponsive for a short period. The code (PHP): https://www.paypal.com/us/cgi-bin/webscr?cmd=p/xcl/rec/pdt-code-outside If I comment out the POST back, it all works fine. I'm able to pin down the problem to once the code enters the while{} loop. Unfortunately, I'm not experienced enough to write a replacement from scratch for the PayPal code, so would really appreciate any ideas on what might be wrong. The POST back goes to ssl://www.sandbox.paypal.com, and I'm using button code and an authorisation token that have all been created via a sandbox test account. Thanks in advance.

• Google Maps API V3: How to jump to a specific marker from outside the map?

  - by Tom

  I have a map with two markers on it. The initial view of the map only shows one marker, and I want to provide a link next to the map that will move the map to the 2nd marker when clicked. Here's a demo of what I want, using v2 of the API: http://arts.brighton.ac.uk/contact-university-of-brighton-faculty-of-arts (note the links below the map) Here's what I have so far: <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(50.823817, -0.135634); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU } , scaleControl: false }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // 1st marker var marker1 = new google.maps.Marker({ position: new google.maps.LatLng(50.823817, -0.135634), map: map, title: 'my title' }); var infowindow = new google.maps.InfoWindow({ content: 'my window content' }); google.maps.event.addListener(marker1, 'click', function() { infowindow.open(map, marker1); }); // 2nd marker var marker2 = new google.maps.Marker({ position: new google.maps.LatLng(51.5262405, -0.074549), map: map, title: 'my 2nd title'}); var infowindow2 = new google.maps.InfoWindow({ content: 'content for my 2nd window' }); google.maps.event.addListener(marker2, 'click', function() { infowindow2.open(map, marker2); }); } </script> So what I'd like to add is a link to marker2, to move the map some 50-odd miles up, e.g. <a href="#marker2">Second location</a>. How would I do this?

• Creating a Large Matrix in ff

  - by Ryan Rosario

  I am trying to create a huge matrix in ff, and I know that ff is good for this sort of thing. But, there is a major problem. The dimensions of the matrix exceed .Machine$max_integer! I am running on a 64 bit machine, using 64bit R and 64bit ff. Is there any way to get around this problem? It's been suggested that R is using the MAXINT value from stdint.h. Is there any way to fix this without changing that file and possibly breaking build? > ffMatrix <- ff(vmode="boolean", dim=c(1e10,1e10)) Error in if (length < 0 || length > .Machine$integer.max) stop("length must be between 1 and .Machine$integer.max") : missing value where TRUE/FALSE needed In addition: Warning message: In ff(vmode = "boolean", dim = c(1e+10, 1e+10)) : NAs introduced by coercion > 1e+10 > .Machine$integer.max [1] TRUE

• EasyXDM passing data issue

  - by Jeff Ryan

  I'm using rpc with XDM, and I can send simple data back and forth easily between child and parent window. But it seems to be limited to simple strings and numbers. The demos on the site only use numbers. When I try to send a json ecoded string, I get a cross domain error. When I use cors, I can make ajax requests fine, but I can't display the child page in the iframe, because the data is returned and not rendered. My question is, how can I render an iframe, and pass complex data back and forth. Or maybe I am doing something wrong?

• Directly call distutils' or setuptools' setup() function with command name/options, without parsing

  - by Ryan B. Lynch

  I'd like to call Python's distutils' or setuptools' setup() function in a slightly unconventional way, but I'm not sure whether distutils is meant for this kind of usage. As an example, let's say I currently have a 'setup.py' file, which looks like this (lifted verbatim from the distutils docs--the setuptools usage is almost identical): from distutils.core import setup setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='Greg Ward', author_email='[email protected]', url='http://www.python.org/sigs/distutils-sig/', packages=['distutils', 'distutils.command'], ) Normally, to build just the .spec file for an RPM of this module, I could run python setup.py bdist_rpm --spec-only, which parses the command line and calls the 'bdist_rpm' code to handle the RPM-specific stuff. The .spec file ends up in './dist'. How can I change my setup() invocation so that it runs the 'bdist_rpm' command with the '--spec-only' option, WITHOUT parsing command-line parameters? Can I pass the command name and options as parameters to setup()? Or can I manually construct a command line, and pass that as a parameter, instead? NOTE: I already know that I could call the script in a separate process, with an actual command line, using os.system() or the subprocess module or something similar. I'm trying to avoid using any kind of external command invocations. I'm looking specifically for a solution that runs setup() in the current interpreter. For background, I'm converting some release-management shell scripts into a single Python program. One of the tasks is running 'setup.py' to generate a .spec file for further pre-release testing. Running 'setup.py' as an external command, with its own command line options, seems like an awkward method, and it complicates the rest of the program. I feel like there may be a more Pythonic way.

• How can I save BioPerl sequence nested features in genbank or embl format?

  - by Ryan Thompson

  In BioPerl, a sequence object can have any number of features, and each of these can have subfeatures nested within them. For example, a feature may be a complete coding sequence of a gene, and its subfeatures might be individual exons that are concatenated to form the full coding sequence. However, when I use BioPerl to write a sequence object to a file in genbank or embl format, only the top-level features are written to the file, not the sub-features nested within the top-level features. How can I store my subfeatures in sequence files? Should I just convert all my subfeatures into top-level features, and then reconstruct the tree structure next time I read in the sequence?

• ASP.NET Canceling the Default Submit Button

  I have an ASP.NET application where there's a few ASP.NET buttons and several plain HTML buttons. Anytime there's a textbox where a user hits enter, the ASP.NET button trys to submit the form. I know I can change the defaultButton, but I don't want there to be any default button. I just want it so when the user presses enter it doesn't do anything. I've tried setting defaultButton to blank, but that doesn't seem to work and I can't seem to find the answer anywhere on the web. What's the code to make this happen? Thanks.
