• How to customize Bootstrap typeahead layout/function for more than just text?

  - by Loolooii

  I'm working on a search functionality for my website and I'm using Bootstrap's typeahead to show the results. So far so good. But what I want is to extend the function so that I could add an image and some other item, say description, etc. According to this post, that is possible: custom typeahead. Basically I need something like this as each result item: <div class="resultContainer"> <div class="resultImage"><img /></div> <div class="resultDesc"></div> <div class="resultLabel"></div> </div> Now it's: <li><a href="#"></a></li> And this doesn't even work with a longer text than the width of the typeahead. So the text doesn't go to the next line and hence doesn't fit the <li>. How can I use the the custom layout I want? (btw I have an array of arrays of results. Each sub-array contains img, desc, etc.). This is what I have right now: Thanks in advance.

• When to drop an IT job

  - by Nippysaurus

  In my career I have had two programming jobs. Both these jobs were in a field that I am most familiar with (C# / MSSQL) but I have quit both jobs for the same reason: unmanageable code and bad (loose) company structure. There was something in common with both these jobs: small companies (in one I was the only developer). Currently I am in the following position: being given written instructions which are almost impossible to follow (somewhat of a fools errand). we are given short time constraints, but seldom asked how long work will take, and when we do it is always too long and needs to be shorter (and when it ends up taking longer than they need it to take, it's always our fault). there is no time for proper documenting, but we get blamed for not documenting (see previous point). Management is constantly screwing me around, saying I'm underperforming on a given task (which is not true, and switching me to a task which is much more confusing). So I must ask my fellow developers: how bad does a job need to be before you would consider jumping ship? And what to look out for when considering taking a job. In future I will be asking about documented procedures, release control, bug management and adoption of new technologies. EDIT: Let me add some more fuel to the fire ... I have been in my current job for just over a year, and the work I am doing almost never uses any of the knowledge I have gained from the other work I have been doing here. Everything is a giant learning curve. Because of this about 30% of my time is learning what is going on with this new product (who's owner / original developer has left the company), 30% trying to find the relevant documentation that helps the whole thing make sense, 30% actually finding where to make the change, 10% actually making the change.

• The perfect web UI framework (with Microsoft stack?) - architecture question?

  - by Igorek

  I'm looking for suggestions for the following issue, and I realize there is really not going to be a perfect answer to my question: I have a UI built in WinForms.NET (v4.0 framework) with WCF back-end and EF4 model objects, that I am looking to port to the web. UI is not huge and is not super complex and is structured well. But it is not a super simple system either. I am looking to pick a technology stack for the web-frontend that will target desktop & partially mobile platforms, provide a good development platform to build on, and facilitate code reuse across UI and back-end tiers... I would rather avoid: custom coding of UI-centric scripts, because they are hard to debug, non-compiled, usually a maintenance nightmare, almost always start to contain business logic, and duplicate some of the logic that back-end tiers have (especially validation) custom-coding for Desktop Web and Mobile Web UI's separately (although I realize that mobile web UI will likely contain fewer of data-entry screens and more reporting screens) non-.NET technology stacks I would love to: target the reporting capabilities of the system toward mobile web browsers not have to write a single line of script (javascript, jquery, etc.) utilize a good collection of controls that produces an elegant UI use .NET for everything The way I see it right now, I need to re-write this app in Silverlight, utilize a 3rd party UI framework like Telerik, and re-do the reports UI again for mobile platforms separately. However, I'm rather concerned about the shelf-life of Silverlight and the needed to deploy a different architecture to deal with mobile platform. Is there an ASP.NET/MVC/Ajax architecture/framework/library that would allow me to get at the power of .NET and without painful (imho) client-side scripting, while providing a decent user experience Thank you

• Android listing design problem with cursors

  - by Priyank

  Hi. I have a following situation in my android app. I have an app that fetches messages from inbox, sent items and drafts based on search keywords. I use to accomplish this by fetching cursors for each manually based on selection by user and then populating them in a custom data holder object. Filter those results based on given keywords and then manually render view with respective data. Someone suggested that I should use a custom Cursor adapter to bind view and my cursor data. So I tried doing that. Now what I am doing is this: Fetch individual cursors for inbox, sent items and drafts. Merge them into one using Merge cursor and then pass that back to my CursorAdapter implmentation. Now where or how do I filter my cursor data based on keywords; because now binding will ensure that they are directly rendered to view on list. Also, some post fetching operation like fetching sender's contact pic and all will be something that I do not want to move to adapter. If I do all this processing in adapter; it'll be heavy and ugly. How could I have designed it better such that it performs and the responsibilities are shared and distributed. Any ideas will be helpful.

• JQuery - Microsoft JScript runtime error: Object expected

  - by ydobonmai

  Below is the content of my .aspx page and the "jquery-ui-1.7.1.custom.min.js" is in the same location as the .aspx file. When I run the website with debugging, I get the below error. I know I am terribly missing something here. Any clue?

• ASP.NET MVC: Can't figure out what VirtualPath is?

  - by Ryan_Pitts

  I have a View that displays a list of images and i am now trying to get it to display the images as thumbnails. Well, i'm pretty sure i got most of it right using VirtualPath's from a custom ActionResult although i can't seem to figure out what it is making the VirtualPath url?? BTW, i'm using XML to store the data from the images instead of SQL. Here is my code: Code from my custom ActionResult: public class ThumbnailResult : ActionResult { public ThumbnailResult(string virtualPath) { this.VirtualPath = virtualPath; } public string VirtualPath { get; set; } public override void ExecuteResult(ControllerContext context) { context.HttpContext.Response.ContentType = "image/bmp"; string fullFileName = context.HttpContext.Server.MapPath("~/Galleries/WhereConfusionMeetsConcrete/" + VirtualPath); using (System.Drawing.Image photoImg = System.Drawing.Image.FromFile(fullFileName)) { using (System.Drawing.Image thumbPhoto = photoImg.GetThumbnailImage(100, 100, null, new System.IntPtr())) { using (System.IO.MemoryStream ms = new System.IO.MemoryStream()) { thumbPhoto.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); context.HttpContext.Response.BinaryWrite(ms.ToArray()); context.HttpContext.Response.End(); } } } } } Code for my Controller: public ActionResult Thumbnail(string id) { return new ThumbnailResult(id); } Code for my View: <% foreach (var image in ViewData.Model) { %> <a href="../Galleries/TestGallery1/<%= image.Path %>"><img src="../Galleries/TestGallery1/thumbnail/<%= image.Path %>" alt="<%= image.Caption %>" /></a> <br /><br /><%= image.Caption %><br /><br /><br /> <% } %> Any help would be greatly appreciated!! Let me know of any questions you have as well. :) Thanks!

• Rails runner command not saving to cache

  - by mark

  Hi I'm having a bit of a problem with a cron task generated by rails whenever plugin that should store remote data in the rails cache for display. What I have is this: schedule.rb set :path, '/var/www/apps/tuexplore/current' every 1.hour do runner "Weather.cache_remote", :environment => :production end calls this model class Weather def self.cache_remote Rails.cache.write('weather_data', Net::HTTP.get_response(URI.parse(WEATHER_URL)).body) end end Calling whenever returns this PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/deploy/.gem/ruby/1.8/bin 0 * * * * /var/www/apps/tuexplore/current/script/runner -e production "Weather.cache_remote" This doesn't work. Calling the weather model method from a controller works fine, but I need to schedule it hourly. The cron task causes a "Cache write: weather_data" entry to appear in the production log but data isn't stored nor output into the page. Additional information, I can log into production console and run Weather.cache_remote, then read the data from the rails cache. I'd be really appreciative if someone could point out the error of my ways. If further explanation is needed please ask. Thanks in advance for any pointers.

• Counting in R data.table

  - by Simon Z.

  I have the following data.table set.seed(1) DT <- data.table(VAL = sample(c(1, 2, 3), 10, replace = TRUE)) VAL 1: 1 2: 2 3: 2 4: 3 5: 1 6: 3 7: 3 8: 2 9: 2 10: 1 Now I want to to perform two tasks: Count the occurrences of numbers in VAL. Count within all rows with the same value VAL (first, second, third occurrence) At the end I want the result VAL COUNT IDX 1: 1 3 1 2: 2 4 1 3: 2 4 2 4: 3 3 1 5: 1 3 2 6: 3 3 2 7: 3 3 3 8: 2 4 3 9: 2 4 4 10: 1 3 3 where COUNT defines task 1. and IDX task 2. I tried to work with which and length using .I: dt[, list(COUNT = length(VAL == VAL[.I]), IDX = which(which(VAL == VAL[.I]) == .I))] but this does not work as .I refers to a vector with the index, so I guess one must use .I[]. Though inside .I[] I again face the problem, that I do not have the row index and I do know (from reading data.table FAQ and following the posts here) that looping through rows should be avoided if possible. So, what's the data.table way?

• Drupal administration theme doesn't apply to Blocks pages (admin/build/block)

  - by hfidgen

  A site I'm creating for a customer in D6 has various images overlaying parts of the main content area. It looks very pretty and they have to be there for the general effect. The problem is, if you use this theme in the administration pages, the images get in the way of everything. My solution was to create a custom admin theme, based on the default one, which has these image areas disabled in the output template files - page.tpl.php The problem is that when you try and edit the blocks page, it uses the default theme and half the blocks admin settings are unclickable behind the images. I KNOW this is by design in Drupal, but it's annoying the hell out of me and is edging towards "bug" rather than "feature" in my mind. It also appears that there is no way of getting around it. You can edit /modules/blocks/block.admin.inc to force Drupal to show the blocks page in the chosen admin theme. BUT whichever changes you then make will not be transferred to the default theme, as Drupal treats each theme separately and each theme can have different block layouts. :x function block_admin_display($theme = NULL) { global $custom_theme; // If non-default theme configuration has been selected, set the custom theme. // $custom_theme = isset($theme) ? $theme : variable_get('theme_default', 'garland'); // Display admin theme $custom_theme = variable_get('admin_theme', '0'); // Fetch and sort blocks $blocks = _block_rehash(); usort($blocks, '_block_compare'); return drupal_get_form('block_admin_display_form', $blocks, $theme); } Can anyone help? the only thing I can think of is to push the $content area well below the areas where the image appear and use blocks only for content display. Thanks!

• In Inform 7, is it possible to use a second noun construct with "pull"?

  - by Beska

  I'll eat my hat if I get a good answer to this...I suspect that although I'm a rank beginner in Inform 7, and I'm guessing this isn't that hard, but there are probably not many people here who are familiar with Inform 7. Still, nothing ventured... I'm trying to create a custom response to a "pull" action. Unfortunately, I think the "pull" action doesn't normally expect a second noun. So I'm trying something like this: The nails are some things in the Foyer. The nails are scenery. Instead of pulling the nails: If the second noun is nothing: say "How? Are you going to pull the nails with your teeth?"; otherwise: say "I don't think that's going to do the job." But while this compiles, and the first part works, the "I don't think..." section is never called...the interpreter just responds "I only understood you as far as wanting to pull the nails." Do I have to create my own custom action for this? Overwrite the standard pull action? Am I missing something simple that will allow me to get this to work?

• How to cope with null results in SQL Tasks that return single rows in SSIS 2005?

  - by JSacksteder

  In a dataflow task, I can slip a rowcount into the processing flow and place the count into a variable. I can later use that variable to conditionally perform some other work if the rowcount was 0. This works well for me, but I have no corresponding strategy for sql tasks expected to return a single row. In that event, I'm returning those values into variables. If the lookup produces no rows, the sql task fails when assigning values into those variables. I can branch on that component failing, but there's a side effect of that - if I'm running the job as a SQL server agent job step, the step returns DTSER_FAILURE, causing the step to fail. I can tell the sql agent to disregard the step failure, but then I won't know if I have a legitimate error in that step. This seems harder than it should be. The only strategy I can think of is to run the same query with a count(*) aggregate and test if that returns a number 0 and if so running the query again without the count. That's ugly because I have the same query in two places that I need to keep in sync. Is there a better way?

• How to get a template tag to auto-check a checkbox in Django

  - by Daniel Quinn

  I'm using a ModelForm class to generate a bunch of checkboxes for a ManyToManyField but I've run into one problem: while the default behaviour automatically checks the appropriate boxes (when I'm editing an object), I can't figure out how to get that information in my own custom templatetag. Here's what I've got in my model: ... from django.forms import CheckboxSelectMultiple, ModelMultipleChoiceField interests = ModelMultipleChoiceField(widget=CheckboxSelectMultiple(), queryset=Interest.objects.all(), required=False) ... And here's my templatetag: @register.filter def alignboxes(boxes, cls): """ Details on how this works can be found here: http://docs.djangoproject.com/en/1.1/howto/custom-template-tags/ """ r = "" i = 0 for box in boxes.field.choices.queryset: r += "<label for=\"id_%s_%d\" class=\"%s\"><input type=\"checkbox\" name=\"%s\" value=\"%s\" id=\"id_%s_%d\" /> %s</label>\n" % ( boxes.name, i, cls, boxes.name, box.id, boxes.name, i, box.name ) i = i + 1 return mark_safe(r) The thing is, I'm only doing this so I can wrap some simpler markup around these boxes, so if someone knows how to make that happen in an easier way, I'm all ears. I'd be happy with knowing a way to access whether or not a box should be checked though.

• Dojo StackContainer children are not resizing on browser maximise/restore

  - by Andy

  Hi. I have the following nested layout in a dojo 1.4 app: BorderContainer 1 -- Stack Container 1 ----BorderContainer 2 ----BorderContainer 3 The StackContainer is sized with width and height 100%. When I resize the browser window using maximise/restore, the StackContainer correctly resizes to the center region of it's parent BorderContainer. The problem I have is that the StackContainer children (BorderContainer 2 and 3) do not get resized to the StackContainer's contentBox. Is there something special you have to do to force a resize of StackContainer children? I have tried calling StackContainer1.resize() but this makes no difference. Thanks in advance. Additional information: Thanks for the reply peller. The widget hierachy that contains the StackContainer is actually a custom widget, so the StackContainer is not actually in a BorderContainer directly, but has its height and width explicitly set to 100%. This works and the StackContainer is resized correctly on browser maximise. The direct children of the stackcontainer are BorderContainers and it is these BorderContainers that do not get resized when the StackContainer is resized. One point to note is that when the StackContainer is created in markup, the stackcontainer children are empty divs. These divs are then used as placeholders for custom widget creation, e.g. var widget = new com.company.widget(params, placeholderDiv); where placeholderDiv is a direct child of the StackContainer in markup. Should I be adding the programatically created 'widget' to the stackcontainer using addChild instead?

• Changing where a resource is pulled during runtime?

  - by Brandon

  I have a website that goes out to multiple clients. Sometimes a client will insist on minor changes. For reasons beyond my control, I have to comply no matter how minor the request. Usually this isn't a problem, I would just create a client specific version of the user control or page and overwrite the default one during build time or make a configuration setting to handle it. Now that I am localizing the site, I'm curious about the best way to go about making minor wording changes. Lets say I have a resource file called Resources.resx that has 300 resources in it. It has a resource called Continue. English value is "Continue", the French value is "Continuez". Now one client, for whatever reason, wants it to say "Next" and "Après" and the others want to keep it the same. What is the best way to accomodate a request like this? (This is just a simple example). The only two ways I can think of is to Create another Resources.resx specific to the client, and replace the .dll during build time. Since I'd be completely replacing the dll, the new resource file would have to contain all 300 strings. The obvious problem being that I now have 2 resource files, each with 300 strings to maintain. Create a custom user control/page and change it to use a custom resource file. e.g. SignIn.ascx would be replaced during the build and it would pull its resources from ClientName.resx instead of Resources.resx. Are there any other things I could try? Is there any way to change it so that the application will always look in a ClientResources.resx file for the overridden values before actually look at the specified resource file?

• YQL + PHP : how to make a facebook login

  - by Jonathan

  Hi! I was reading some stuff about the YQL api that Yahoo! has provided, I am not sure, but it appears to be a collection of lots of third party api into one common language, right? what I don't get is how to make the facebook login through it so I can get the user profile data... My project is to add a facebook(and other social networks) form login, because the website won't have his own login, people will have to use a social network to link in. Then I thought the YQL would help me out with this task so I wouldn't have to develop lots of functions to each one of the networks. Reading this http://developer.yahoo.com/yql/guide/yql-code-examples.html#sdk_yql, I understood how to make a Yahoo login so I can access some private data, but couldn't find how I could do it with facebook and others So my question... Can YQL help me with this? Can you give me a simple example of a facebook session using it within PHP? Are there alternatives to aid me in this task? thanks, Jonathan

• Windows Services in Win7?

  - by Brandi

  I am trying to make a service that spawns a desktop application, and then watches to make sure it restarts again if it is closed. . I would like it to basically spawn the process and then forget about it, allowing to act like a normal interactive application. (Apparently this is much easier to do in XP and before, but I need this for XP, Vista, and 7) My problem now is that either it shows up invisible if I use process.start() with desktop interactive checked, and if I directly spawn a form it asks "Do you REALLY want to do this?!" and then the whole screen goes blank EXCEPT for my program. I just want this to be an inoffensive background app. I have the app working well, I just need to figure out how to spawn it from a service without all the trouble. I am finding all of this stuff that says "Don't make services that have UI", but first off this was a requirement that was given to me. (Boss does not want it to be a scheduled task) Also, I noticed that the Task scheduler is itself a service, and it does not have any problem spawning user interactive applications. Why can't I do that too? What am I doing wrong?

• How can I send rich emails using the user's mail client ?

  - by Brann

  I need my .net program to send rich emails (usually containing table data, around 20 columns x 10 rows) using the user's mail infrastructure, allowing him to review/edit the mail before sending it, and storing the mail in his 'sent items' folder. mailto: seems the obvious choice, but unfortunately, it doesn't support neither attachments nor html bodies. It seems some clients support some extra features (e.g. Outlook 97 used to support a &Attach tag, but this is not the case for more recent versions). I could use mailto and try to format the text body to look nice (using tabs, etc), but this isn't really elegant and wouldn't support huge data. using automation seems a very huge task, as I would need to automate dozens of clients (4 or 5 versions of outlook, lotusnotes, thunderbid, etc.) ... This would be a huge task and it's not really my core business ... I could send emails through code and write my own mail form to let the user edit the mail, but this would have a lot of drawbacks : the user would need to manually configure the mail server settings he wouldn't have access to his contact directory the mail wouldn't be sent in his sent items folder This seems a quite common issue, but I haven't found any satisfying solution yet ; does someone knows of a library supporting this (ie containing automation logic for most mainstream email clients?). Or an alternative to mailto ?

• Limit TCP requests per IP

  - by asmo

  Hello! I'm wondering how to limit the TCP requests per client (per specific IP) in Java. For example, I would like to allow a maximum of X requests per Y seconds for each client IP. I thought of using static Timer/TimerTask in combination with a HashSet of temporary restricted IPs. private static final Set<InetAddress> restrictedIPs = Collections.synchronizedSet(new HashSet<InetAddress>()); private static final Timer restrictTimer = new Timer(); So when a user connects to the server, I add his IP to the restricted list, and start a task to unrestrict him in X seconds. restrictedIPs.add(socket.getInetAddress()); restrictTimer.schedule(new TimerTask() { public void run() { restrictedIPs.remove(socket.getInetAddress()); } }, MIN_REQUEST_INTERVAL); My problem is that at the time the task will run, the socket object may be closed, and the remote IP address won't be accessible anymore... Any ideas welcomed! Also, if someone knows a Java-framework-built-in way to achieve this, I'd really like to hear it.

• Zend_Auth and database session SaveHandler

  - by takeshin

  I have created Zend_Auth adapter implementing Zend_Auth_Adapter_Interface (similar to Pádraic's adapter) and created simple ACL plugin. Everything works fine with default session handler. So far, so good. As a next step I have created custom Session SaveHandler to persist session data in the database. My implementation is very similar to this one from parables-demo. Seems that everything is working fine. Session data are properly saved to the database, session objects are serialized, but authentication does not work when I enable this custom SaveHandler. I have debugged the authentication and all works fine up till the next request, when the authentication data are lost. I suspected, that is has something to do with the fact, that I use $adapter->write($object) instead $adapter->write($string), but the same happens with strings. I'm bootstrapping Zend_Application_Resource_Session in the first Bootstrap method, as early as possible. Does Zend_Auth need any extra configuration to persist data in the database? Why the authentity is being lost?

• RegisterStartupScript doesn't appear to be working on page postback within update panel

  - by Jen

  OK - so am working on a system that uses a custom datepicker control (I know there are other ones out there.. but for consistency would like to understand why my current issue is happening and fix it). So its a custom user control with a textbox and on Page_PreRender does this: protected void Page_PreRender(object sender, EventArgs e) { string clientScript = @" $(function(){ $('#" + this.Date1.ClientID + @"').datepicker({dateFormat: 'dd/mm/yy', constrainInput: true}); });"; Page.ClientScript.RegisterStartupScript(this.GetType(), this.ClientID, clientScript, true); //Type t = this.GetType(); //if (!Page.ClientScript.IsStartupScriptRegistered(t, this.ClientID)) //{ // Page.ClientScript.RegisterStartupScript(t, this.ClientID, clientScript, true); //} } Ignore commented out stuff - that was me trying something different - didn't help. My issue is that this all works fine when I load the page. But if I select something from a dropdownlist causing a page postback - when I click into my date fields they stop working. As in I should be able to click into the textbox and a nice calendar control appears. But after postback there is no nice calendar control appearing! It's currently all wrapped (in the hosting page) inside an update panel. So I comment out the update panel stuff and the dates are working after page postback. So it appears to be something related to that update panel. Any suggestions please? Thanks!!

• heroku logs --ps run showign nothing

  - by Zarne Dravitzki

  I have two running apps on heroku staging and production. They are near identical enviornments. (Staging has extra configs IE RailsFootnotes, Bullet gem) When I run heroku logs --ps run --app jl-staging Returns as logs like 2012-08-30T01:30:42+00:00 heroku[run.1]: Starting process with command `bundle exec rake jewellover:warn_users` This log is a Task set to run with Heroku Schedular Free. Everything Works perfect but when I do the same with heroku logs --ps run --app jl-production There are no results. No heroku[run.1] process logs. Both environments have the same scheduled tasks, albeit at different times but none the less both run scheduled tasks at specified times. Is there something im missing about heroku[run.1] processes in production env? Does heroku only keep the -ps logs for a certain amount of time? It seems to show less activity than the normal logs. Maybe only show 24hrs worth of logs rather than Last 100 logs... I need to log and debug the [run.1] process from the production env... specifically the jewellover:warn_users task. any ideas?

• one two-directed tcp socket OR two one-directed? (linux, high volume, low latency)

  - by osgx

  Hello I need to send (interchange) a high volume of data periodically with the lowest possible latency between 2 machines. The network is rather fast (e.g. 1Gbit or even 2G+). Os is linux. Is it be faster with using 1 tcp socket (for send and recv) or with using 2 uni-directed tcp sockets? The test for this task is very like NetPIPE network benchmark - measure latency and bandwidth for sizes from 2^1 up to 2^13 bytes, each size sent and received 3 times at least (in teal task the number of sends is greater. both processes will be sending and receiving, like ping-pong maybe). The benefit of 2 uni-directed connections come from linux: http://lxr.linux.no/linux+v2.6.18/net/ipv4/tcp_input.c#L3847 3847/* 3848 * TCP receive function for the ESTABLISHED state. 3849 * 3850 * It is split into a fast path and a slow path. The fast path is 3851 * disabled when: ... 3859 * - Data is sent in both directions. Fast path only supports pure senders 3860 * or pure receivers (this means either the sequence number or the ack 3861 * value must stay constant) ... 3863 * 3864 * When these conditions are not satisfied it drops into a standard 3865 * receive procedure patterned after RFC793 to handle all cases. 3866 * The first three cases are guaranteed by proper pred_flags setting, 3867 * the rest is checked inline. Fast processing is turned on in 3868 * tcp_data_queue when everything is OK. All other conditions for disabling fast path is false. And only not-unidirected socket stops kernel from fastpath in receive
