• Using Angularjs with server side templates

  - by codecollision

  For SEO purposes the server renders out the full html template for a given URL on initial load. The site uses angularjs which detects the URL route and renders a client template from the JSON API. For example, you navigate to: /blog/post-title Server responds with post-title content. Angular loads, detects route: /blog/:post_slug and begins to load JSON and render client side template from response. Obviously what Angular does is fine when links are followed after the initial load, but on first load it duplicates effort. My question is if there is a clean way to prevent this situation.

• Model View Presenter plus ASP.NET Web Service; where does the asmx live?

  - by Dirk

  I've been slowly transitioning from a traditional web forms architecture to the MVP pattern (Passive View). So far, it's been fairly easy to implement b/c the views I've dealt with have all employed a classic PostBack model. However, I've come across my first view that will refresh portions of itself via web services. I can't grok where the web service should live (Presenter I think) or how to expose that asmx end point to my View while still maintaining the clean separation of concerns/testability that MVP affords me. I've searched far and wide for some examples on how this might be implemented and have come up with nothing. Please help!

• "Mail merge"-like functionality in Dreamweaver, or in any other web editing tool?

  - by Chris Farmer

  I have inherited several related, low-traffic web sites to manage and edit. These sites are implemented with static html, and they've accrued lots of stray tags and other cruft. I want to try to clean these up and migrate them to some common page template framework to simplify design and data changes and improve overall consistency. The pages will change on the timescale of weeks, and since the current web hosting plan does not support any dynamic server technologies, I was hoping to just use Dreamweaver or some other tool to merge my content data with some templating structure. I'd like to do content updates every several days and then run the content back through my templates, resulting in new static html that I can upload to the host. Do any tools support this kind of poor-man's data-driven web application? Are there better ways to approach this problem, aside from moving to a new hosting plan and using ASP.NET or PHP?

• Memory leak with ContextMenuStrip

  - by Dave

  I'm creating a lot of custom controls and adding them to a FlowLayoutPanel. There is also a ContextMenuStrip created and populated at design time. Every time a control is added to the panel it has its ContextMenuStrip property assigned to this menu, so that all controls "share" the same menu. But I noticed when the controls are removed from the panel and disposed of, the memory in use in Task Manager doesn't drop. It rises around 50kB every time a control is created and added to the layout panel. I downloaded the trial of .NET Memory Profiler and it showed there were references to the menu strip hanging around after the controls were disposed. I changed the code to explicitly set the ContextMenuStrip property to null before disposing of the control, and yep, the memory is now released. Why is this? Shouldn't the GC clean up this type of thing?

• Creating a contact form using divs with 4 extra divs for "Corners"?

  - by mark smith

  Hi there, i have tried to create a contact form (a standard form, square in nature but with rounded corners)... I can't use the CSS3 specs so i have an image for each corner.. I have set the images on the background-image and no repeat but it seems if the div is empty then it doesn't display, is there a hack - although prefer an alternative clean method :-) So on the top level i presume i have 1 div for the Upper-Left (corner) and then the upper-middle (just has a color assigned) and then a div for the upper-right (corner) .. so i presume i need to float all these to the left??? Or am i missing something? Thanks in advance

• Rollback to a specific moment with PostgreSQL

  - by mada54

  Hi, Is there a way to rollback to a specific starting point. Im looking for something like this. Start specific_point; Now after this, an other application connected with the SAME login will insert & delete datas (webservices with crud operations) for about 2 minutes doing tests. Each webservice call is declared as a transaction with Spring Ws. After that i want to rollback to the specific_point to have a clean database to a known previous state. I was thinking that ROLLBACK TO SAVEPOINT foo; was the solution but not unfortunately? Any idea ? Configuration: PostgreSQL 8.4 / windows XP Regards

• 1 bug to kill... Letting PHP Generate The Canonical.

  - by Sam

  Hi folks, for building a clean canonical url, that always returns 1 base URL, im stuck in following case: <?php # every page $extensions = $_SERVER['REQUEST_URI']; # path like: /en/home.ast?ln=ja $qsIndex = strpos($extensions, '?'); # removes the ?ln=de part $pageclean = $qsIndex !== FALSE ? substr($extensions, 0, $qsIndex) : $extensions; $canonical = "http://website.com" . $pageclean; # basic canonical url ?> <html><head><link rel="canonical" href="<?=$canonical?>"></head> when URL : http://website.com/de/home.ext?ln=de canonical: http://website.com/de/home.ext BUT I want to remove the file extension aswell, whether its .php, .ext .inc or whatever two or three char extension .[xx] or .[xxx] so the base url becomes: http://website.com/en/home Aaah much nicer! but How do i achieve that in current code? Any hints are much appreciated +! (other advices for proper canonical usage in this multi-lingual environment are welcome as well)

• Removing unused selectors in a CSS stylesheet?

  - by Legend

  I've been developing a web app for a few weeks now and ended up with about a 1000 lines. I am sure not all the selectors are being used and am trying to clean it up. At the same time, I don't want to do it manually for obvious reasons. Is there a safe and an efficient way to remove unused selectors? For this, am I supposed to navigate the entire website to let it know which selectors are not being used? (I use javascript to add some selectors so these might not show up until a particular usecase is seen)

• How do I display the current value of an Android Preference in the Preference summary?

  - by nyenyec

  This must come up very often. When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the Preference summary. Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the PreferenceActivity I'd like the user to see: "Discard old messages" <- title "Clean up messages after x days" <- summary where x is the current Preference value Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).

• Delete MSMQ Queue During Uninstall

  - by Todd Kobus

  Is it possible to delete a private message queue that was created by the service user? During uninstallation, we would like to clean up any message queues created by our application. For security purposes, access to these queues has been restricted to the current user (ServiceUser). During uninstall, we have admin privileges, but still get an access denied MessageQueueException when we attempt to delete the queue or modify the privs on the queue. Here is the cleanup code: public void DeleteAppQueues() { List<string> trash = new List<string>(); var machineQueues = MessageQueue.GetPrivateQueuesByMachine("."); foreach (var q in machineQueues) { if (IsAppQueue(q.QueueName)) { trash.Add(".\\" + q.QueueName); } q.Dispose(); } foreach (var queueName in trash) { try { using (MessageQueue delQueue = new MessageQueue(queueName)) { delQueue.SetPermissions("Everyone", MessageQueueAccessRights.FullControl, AccessControlEntryType.Allow); } MessageQueue.Delete(queueName); } catch (MessageQueueException ex) { // ex.Message is "Access to Message Queuing system is denied." } } }

• Allowing AsyncTask to Manipulate Values in Different Activity Classes

  - by Matt

  Hi guys, This title may seem strange, so let me try to explain what I'm trying to do. I have several activity classes, each representing a different view in my application. My initial activity class gets loaded when the application launches. The user enters values and eventually a TCP socket is opened, and I then use AsyncTask to listen for and respond to messages from the server. I'd like for this AsyncTask class to essentially listen until the app is closed/error condition reached, and be able to update values in other activity classes after they are started. Does this make sense (it's been a long, frustrating night)? I know that static activity class references are bad practice, and touching the UI thread from other activities is bad as well, but I'm having trouble finding a clean solution to this problem. Maybe using AsyncTask is not the best approach here? Should I be using a service instead or something else entirely? Thanks in advance.

• Operator + for matrices in C++

  - by cibercitizen1

  I suppose the naive implementation of a + operator for matrices (2D for instance) in C++ would be: class Matrix { Matrix operator+ (Matrix other) const { Matrix result; // fill result with *this.data plus other.data return result; } } so we could use it like Matrix a; Matrix b; Matrix c; c = a + b; Right? But if matrices are big this is not efficient as we are doing one not-necessary copy (return result). Therefore, If we wan't to be efficient we have to forget the clean call: c = a + b; Right? What would you suggest / prefer ? Thanks.

• Maintaining a common set of Eclipse preferences

  - by Robert Munteanu

  Whenever I switch workspaces/Eclipse installs I need to copy/redo the preferences: compiler settings; font sizes/families; code formatter; java code templates; editor templates; code clean-ups; I would like to maintain these settings in an unitary way, preferrably under source control. How can I do that? I know about 'copy settings' when creating a new workspace, but it does not keep updated copies.

• NoSQL replacement for memcache

  - by Juan Antonio Gomez Moriano

  We are having a situation in which the values we store on memcache are bigger than 1MB. It is not possible to make such values smaller, and even if there was a way, we need to persist them to disk. One solution would be to recompile the memcache server to allow say 2MB values, but this is either not clean nor a complete solution (again, we need to persist the values). Good news is that We can predict quite acurately how many key/values pair we are going to have We can also predict the total size we will need. A key feature for us is the speed of memcache. So question is: is there any noSQL replacement for memcache which will allow us to have values longer than 1MB AND store them in disk without loss of speed? In the past I have used tokyotyrant/cabinet but seems to be deprecated now. Any idea?

• Make multiple targets in 'all'

  - by Hiett

  i'm trying to build a debug and release version of a library with a Makefile and copy those libraries to the relevant build directories, e.g. .PHONY: all clean distclean all: $(program_NAME_DEBUG) $(CP) $(program_NAME_DEBUG) $(BUILD_DIR)/debug/$(program_NAME_DEBUG) $(RM) $(program_NAME_DEBUG) $(RM) $(program_OBJS) $(program_NAME_RELEASE) $(CP) $(program_NAME_RELEASE) $(BUILD_DIR)/release/$(program_NAME_RELEASE) $(RM) $(program_NAME_RELEASE) $(RM) $(program_OBJS) $(program_NAME_DEBUG): $(program_OBJS) $(LINK_DEBUG.c) -shared -Wl,-soname,$(program_NAME_DEBUG) $(program_OBJS) -o $(program_NAME_DEBUG) $(program_NAME_RELEASE): $(program_OBJS) $(LINK_RELEASE.c) -shared -Wl,-soname,$(program_NAME_RELEASE) $(program_OBJS) -o $(program_NAME_RELEASE) The 1st target in all (program_NAME_DEBUG) compiles OK but the 2nd, (program_NAME_RELEASE) produces the following error: libGlamdring_rel.so make: libGlamdring_rel.so: Command not found make: *** [all] Error 127 libGlamdring_rel.so is the value of program_NAME_RELEASE It doesn't seem to be recognising the 2nd target as it does the 1st?

• jQuery function in .click() etc

  - by Martind

  Hi all. So normally, I do it like this: $('#selectRoom a').click( function(e) { e.preventDefault(); // To prevent the default behavior (following the link or adding # to URL) // Do some function specific logic here }); However, I would like to do it like this, to clean things up (and be able to reuse): $('#selectRoom a').click( selectRoom ); function selectRoom () { e.preventDefault(); // To prevent the default behavior (following the link or adding # to URL) // Do some function specific logic here } The problem is, i cant pass the "e" event-handler to the function, then the selectRoom() function is called on load. i.e: $('#selectRoom a').click( selectRoom(e) ); Can I fix this somehow?

• Silverlight 4 application on localhost runs extremely slow

  - by rams

  Silverlight 4 app running in IE8 and hosted on VS2010 internal webserver. The website takes atleast a minute to download the xap and code runs slow on client (IE8). I am running the app in debug mode and have turned intellitrace off. Symbol loading is also turned off. However if I kill the VS webserver, clean the solution, the app runs fast. 3 debugging sessions later, the app slows to a crawl. Have also tried turning off McAfee live scanning but no use. Looked in event log for any clue but found none. What could be the cause of the slowness? TIA rams

• How does hibernate use an empty string for an equality restriction?

  - by Stephen

  I have a column that potentially has some bad data and I can't clean it up, so I need to check for either null or empty string. I'm doing a Hibernate Criteria query so I've got the following that returns incorrectly right now: Session session = getSessionFactory().openSession(); Transaction tx = session.beginTransaction(); Criteria myCriteria = session.createCriteria(Object); ... myCriteria.add(Restrictions.or(Restrictions.isNull("stringColumn"), Restrictions.eq("stringColumn", ""))); List<Objects> list = myCriteria.list(); I can't get it to properly return the results I'd expect. So as an experiment I changed the second restriction to read: Restrictions.eq("stringColumn", "''") And it started returning the expected results, so is hibernate incorrectly translating my empty string (e.g. "") into a SQL empty string (e.g. ''), or am I just doing this wrong?

• Does Anyone Know Of A Solid Web Example Using ASP.NET MVC1 or MVC2, NHibernate, Fluent NHibernate &

  - by Sara

  I am looking for solid non-console examples of how to use ASP.NET MVC1 or MVC2, NHibernate, Fluent NHibernate & Castle. I looked at Sharp Architecture and its just too much to digest for my newbie mind. I need a clean, clear, concise Step A, Step B, Step C tutorial or a solid example that is a web application and not a console application. I have searched and searched and searched and I have found incomplete examples (examples with just enough information to make me say where does that code go), console applications and no good web application examples. Does anyone know of a COMPLETE web example? If I see another console example, I'm going to scream....

• How to figure out why ssh session does not exit sometimes?

  - by WilliamKF

  I have a C++ application that uses ssh to summon a connection to the server. I find that sometimes the ssh session is left lying around long after the command to summon the server has exited. Looking at the Centos4 man page for ssh I see the following: The session terminates when the command or shell on the remote machine exits and all X11 and TCP/IP connections have been closed. The exit status of the remote program is returned as the exit status of ssh. I see that the command has exited, so I imagine not all the X11 and TCP/IP connections have been closed. How can I figure out which of these ssh is waiting for so that I can fix my summon command's C++ application to clean up whatever is being left behind that keeps the ssh open. I wonder why this failure only occurs some of the time and not on every invocation? It seems to occur approximately 50% of the time. What could my C++ application be leaving around to trigger this?

• How to determine files that are subjected to filter via gitattributes when filter is executed?

  - by rasjani

  I have bunch of ruby scripts in a git repository and it seems to be really hard to enforce people to write properly indented code. I also have a small ruby script that formats to code to specific standard and now i would like to run that as a a filter script so that junk wont get committed into repository. echo "*.rb filter=rubyfilter" > .gitattributes echo "[filter \"rubyfilter\"]" >> .git/config echo " clean = /home/rasjani/bin/rbeauty" >> .git/config echo " smudge = /home/rasjani/bin/rbeauty" >> .git/config does the dirty trick git side but the ruby script should then process the files affected: how / where do i look those up from ?

• Xcode 3.1.2 locks up when loading C++ project...?

  - by Stabledog

  I have a project which builds correctly from the command line. On one of my Macs (10.5) running Xcode 3.1.2, I can load it and build it in the Xcode IDE. On my other Mac (same configuration of software), Xcode sometimes loads the project, but always locks up with a spinning beach ball at some point before the build is done. Sometimes this occurs as the project is loaded, sometimes late in the build. I've tried doing a 'clean' on the project, I've tried pulling in the source code fresh from source control. So far, no luck -- I have to kill Xcode and in effect, cannot develop on this particular Mac. I've uninstalled and reinstalled Xcode. Any clues?

• Trick to getting initWithNibFile to be invoked?

  - by PhazeZero

  I've implemented a View Controller, and I'm trying to do some very basic initialization in initWithNibFile...which I understand to be the designated initializer for View Controller objects. I've tried to put breakpoints on the code, and have put very simple NSLog statements into it as well. Regardless...I'm not seeing it be executed (and the object i'm attempting to alloc/init inside the function is also not being allocated - so I'm about 99% sure I'm not hitting the code. Is there something I need to do elsewhere to cause this method to be invoked? I'm getting a clean build, no warnings or errors. And the app successfully loads up the View, and I can invoke a ButtonClick method I've coded and connected to this same View Controller. Any suggestions would be appreciated. TC

• How to find foreign-key dependencies pointing to one record in Oracle?

  - by daveslab

  Hi folks, I have a very large Oracle database, with many many tables and millions of rows. I need to delete one of them, but want to make sure that dropping it will not break any other dependent rows that point to it as a foreign key record. Is there a way to get a list of all the other records, or at least table schemas, that point to this row? I know that I could just try to delete it myself, and catch the exception, but I won't be running the script myself and need it to run clean the first time through. I have the tools SQL Developer from Oracle, and PL/SQL Developer from AllRoundAutomations at my disposal. Thanks in advance!
