• How to use the watchdog timer in a RTOS?

  - by user946230

  Assume I have a cooperative scheduler in an embedded environment. I have many processes running. I want to utilize the watchdog timer so that I can detect when a process has stopped behaving for any reason and reset the processor. In simpler applications with no RTOS I would always touch the watchdog from the main loop and this was always adequate. However, here, there are many processes that could potentially hang. What is a clean method to touch the watchdog timer periodically while ensuring that each process is in good health? I was thinking that I could provide a callback function to each process so that it could let another function, which oversees all, know it is still alive. The callback would pass a parameter which would be the tasks unique id so the overseer could determine who was calling back.

• Is it so bad to have heaps of elements in your DOM?

  - by alex

  I am making a real estate non interactive display for their shop window. I have kicked jCarousel into doing what I want: Add panels per AJAX Towards the end of the current set, go and AJAX some new panels and insert them This works fine, but it appears calling jQuery's remove() on the prior elements cause an ugly bump. I'm not sure if calling hide() will free up any resources, as the element will still exist (and the element will be off screen anyway). I've seen this, and tried carousel.reset() from within a callback. It just clears out all the elements. This will be running on Google Chrome on Windows XP, and will solely by displaying on LCD televisions. I am wondering, if I can't find a reasonable solution to remove the extra DOM elements, will it bring my application to a crawl, or will Chrome do some clever garbage collecting? Or, how would you solve this problem? Thanks

• Anonymous iterator blocks in Clojure?

  - by Checkers

  I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of anonymous iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

• Is there a single query that can update a "sequence number" across multiple groups?

  - by Drarok

  Given a table like below, is there a single-query way to update the table from this: | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | NULL | | 2 | 1 | 2010-04-27 | NULL | | 3 | 2 | 2010-04-28 | NULL | | 4 | 3 | 2010-04-28 | NULL | To this (note that created_at is used for ordering, and sequence is "grouped" by type_id): | id | type_id | created_at | sequence | |----|---------|------------|----------| | 1 | 1 | 2010-04-26 | 1 | | 2 | 1 | 2010-04-27 | 2 | | 3 | 2 | 2010-04-28 | 1 | | 4 | 3 | 2010-04-28 | 1 | I've seen some code before that used an @ variable like the following, that I thought might work: SET @seq = 0; UPDATE `log` SET `sequence` = @seq := @seq + 1 ORDER BY `created_at`; But that obviously doesn't reset the sequence to 1 for each type_id. If there's no single-query way to do this, what's the most efficient way? Data in this table may be deleted, so I'm planning to run a stored procedure after the user is done editing to re-sequence the table.

• VisualStudio: Toggle Archive Attribute When Saving File?

  - by John Dibling

  We use Tortoise CVS in out shop, but in my last job we used Visual SourceSafe. VSS is generally a pile, but it did have one nice feature. You could right-click on a branch and ask it for a list of all the files you had checked-out. As far as I can tell there is no similar feature in CVS. So what I'm looking for is some kind of VS plusgin that will automatically reset (turn off) the archive attribute when saving a file. Then I can recursively dir to find the files I have checked-out. Does anyone know of a VS plugin or something I can do to get this behavior? Or is there something else I can do in CVS to get my ultimately desired result?

• UITableView: Highlighted cell after switching back views

  - by Matthias

  Hi, I'm using a UINavController together with some UITableViews to display a kind of drill down for some data (e.g. like the Contact App). Works well. The only problem I have is, when I select a cell in the first table view it is highlighted, then the view switches to the next level and then, if I go back to the first level, the cell is still highlighted. So, how can I reset the highlighting when switching back? Thanks for your help. Regards Matthias

• Is there a way to access a php class method using javascript through jquery?

  - by Starx

  I have a js script, which is $("#feedbacksubmit").click(function() { if($("#frmfeedback").valid()) { var tname = $("#name").val(); var temail = $("#email").val(); var tphone = $("#phone").val(); var tcontent = $("#content").val(); var tsend = $(this).attr('ts'); $.post ( "bll/index.php", { action: 'mailfeedback', name: tname, email: temail, phone: tphone, content: tcontent, send: tsend }, function(data) { $('.msgbox').html(data); $("#frmfeedback")[0].reset(); }); return false; } }); however, I am trying to see if there is a way to access the class method of bll/index.php directly from the script, instead of posting parameters, to access it

• subviews show confused rotated state after a modal dialog is displayed

  - by deafgreatdane

  I've created a custom UIViewController that mimics the UISplitViewController. It manages two child view controllers that get displayed in the left & right body area while in landscape and hides the left to show in a popover when in portrait. It works fine, using the didRotateFromInterfaceOrientation: and willRotateToInterfaceOrientation: messages to reset the location and sizing of the child views. All the views and child controllers are loaded from a nib. This custom view controller is shown inside a UINavigationController. The trouble arises after one of the child view controllers uses presentModalViewController. If the device was rotated after the views were initialized (but before the modal controller is shown), after the modal dialog is dismissed, the left and/or body views will be re-rendered in a different rotation than they were before the modal dialog was changed. I'm wondering if folks have had a similar problem, and what the solution is. I'm sure sample code would be helpful, but it'll take a bunch of work to distill it into a runnable sample.

• Boost Shared Pointers and Memory Management

  - by Izza

  I began using boost rather recently and am impressed by the functionality and APIs provided. In using boost::shared_ptr, when I check the program with Valgrind, I found a considerable number of "Still reachable" memory leaks. As per the documentation of Valgrind, these are not a problem. However, since I used to use the standard C++ library only, I always made sure that any program written is completely free from memory leaks. My question is, are these memory leaks something to worry about? I tried using reset(), however it only decrements the reference count, doesn't deallocate memory. Can I safely ignore these, or any way to forcibly deallocate the memory allocated by boost::shared_ptr? Thank you.

• disable download of my paid app in Android

  - by Boy

  I have a paid app in the store which will remove the ads in another app when it is installed on that device. Now I want to remove this 'remove ads' app, as I want to have an in-app payement for this for instance (or maybe I just keep the ads version only). But the problem is, if I unpublish the app, people who bought it will not be able to download it again when they get a new phone or reset their phone. How to I keep the app in the Play Store, but prevent people from buying it? Is this possible? My backup plan is: make the app cost 10.000 euro's and put in the message that this app should not be bought anymore. But I don't like that...

• How to get rid of bogus changes in git?

  - by zaza

  I'm a happy user of PortableGit 1.7.0.2. Today I wanted to pull a project changes from GitHub.com repository, so I did git pull. It failed with the following message: error: Your local changes to 'main.rb' would be overwritten by merge. Aborting.. I didn't care about the local changes so I typed git reset --hard HEAD (git clean from here didn't help neither), but it didn't work. When asked for git status I was still able to see the file as modified. git diff showed me that each line of the file has been modified, while git diff -b showed no differences at all, so I guess this is a line ending issue. Which is strange because the code is only pushed from Windows machines. Anyway, the question is: how can I ignore the local, bogus changes and merge with the latest changes from the remote repository?

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• Git: How do I rewind the Master branch on the remote origin

  - by user277260

  I made 5 commits to Master branch when bug hunting on a private project and pushed them to the remote origin (my own private vps). Then I saw that commits 4 and 5 were going to cause trouble elsewhere and I need to undo them, so I checked out commit 3 again, made a new branch "Dev" from that point, and did a few more commits fixing the issue properly. Then I did git reset --hard HEAD~2 on Master to pull it back to the point that I branched Dev. Then I did git merge to fast forward Master back to the end of the Dev branch. So now I have a local repository, with Dev and Master both pointing to the same, up to date version of the project with the latest bug fix. Problem is, when I try to push the project now to the origin, it fails and gives me an error message: ! [rejected] master - master (non-fast forward) error: failed to push some refs to 'myserver...myproject.git' What have I done wrong, and how do I fix it? Thanks

• How to disable typing in values in Dojo's NumberSpinner?

  - by callie16

  Hi, is there a way to disable typing in of values in the NumberSpinner of Dojo? Or is there a way for me to set back a previous value to it? Here's a sample situation: I have a spinner where the range is 1-3. However, the user types in an invalid value... say, a letter. The usual error handling happens. However, if the user deletes the value and focuses out (e.g. goes to another widget/control/etc. in the page), the spinner stays blank. Either I reset it to the last valid value or I disable typing so that the user can just use the up and down arrows to manipulate the widget. Any thoughts? Thanks!

• How to force ListView to show first page programmatically

  - by doekman

  I have a paged ASP.NET ListView. The data shown is filtered, which can be controlled by a form. When the filter form changes, I create a new query, and perform a DataBind. The problem however, when I go to the next page, and set a filter, the ListView shows "No data was returned". That is not weird, because after the filter is applied, there is only one page of data. So what I want to do is reset the pager. Is that a correct solution to the problem? And how do I do that?

• How do I clear MVC client side validation errors when a cancel button is clicked when a user has inv

  - by Sci-fi

  I have a partial view that is rendered within a main view. The partial view takes advantage of System.ComponentModel.DataAnnotations and Html.EnableClientValidation(). A link is clicked, and div containing the partial view is displayed within a JQuery.Dialog(). I then click the save button without entering any text in my validated input field. This causes the client side validation to fire as expected, and display the '*required' message beside the invalid field. When the cancel button is clicked, I want to reset the client side MVC validation back to it's default state and remove any messages, ready for when the user opens the dialog again. Is there a recommended way of doing this?

• How do I change the Unit:Characters in Matlab?

  - by Jonas

  For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

• How to run a command on a remote Windows system as a non-admin user with WMI?

  - by John

  I have a script written in Visual Basic that starts a process (given to the script as an argument) on a remote system (again, given as an argument) using WMI. This script works fine when using an Administrator account on the remote system, but when using a non-administrator account, I get the following error: ConnectServer Failed w/ (-2147024891) Access is denied. I'd like to be able to run processes on remote systems as a non-administrator user with this script, and I'm pretty sure the problem is due to security settings on the remote system, but I've not been able to reset the right ones.

• Android sql creating database once

  - by semajhan

  One thing i'm not understanding is how to create the database and data just once in an android application. I extend SQLiteOpenHelper and use a DataHelper class that to manipulate data. Now, I have addEvent() and updateEvent() within the DataHelper class. I create an instance of DataHelper in my Activity and addEvent() a couple of times to insert data. Well, now I don't know how to just do that once. If I restart the app, its just going to "addEvent()" again and so the data is being reset every time. Sorry for the probably really REALLY noob question. The only solution I found was not using the DataHelper class and just adding data "manually" within the onCreate() method in SQLiteOpenHelper.

• jQuery/JSON/PHP failing

  - by user730936

  I am trying to call a php script that accepts JSON data, writes it into a file and returns simple text response using jQuery/AJAX call. jQuery code : $("input.callphp").click(function() { var url_file = myurl"; $.ajax({type : "POST", url : url_file, data : {'puzzle': 'Reset!'}, success : function(data){ alert("Success: " + data); }, error : function (data) { alert("Error: " + data); }, dataType : 'text' }); }); PHP Code : <?php $thefile = "new.json"; /* Our filename as defined earlier */ $towrite = $_POST["puzzle"]; /* What we'll write to the file */ $openedfile = fopen($thefile, "w"); fwrite($openedfile, $towrite); fclose($openedfile); echo "<br> <br>".$towrite; ?> However, the call is never a success and always gives an error with an alert "Error : [Object object]".

• Best Solution For Authentication in Ruby on Rails

  - by Dan Wolchonok

  I'm looking for a pre-built solution I can use in my RoR application. I'm ideally looking for something similar to the ASP.NET Forms authentication that provides email validation, sign-up controls, and allows users to reset their passwords. Oh yeah, and easily allows me to pull the user that is currently logged into the application. I've started to look into the already written pieces, but I've found it to be really confusing. I've looked at LoginGenerator, RestfulAuthentication, SaltedLoginGenerator, but there doesn't seem to be one place that has great tutorials or provide a comparison of them. If there's a site I just haven't discovered yet, or if there is a de-facto standard that most people use, I'd appreciate the helping hand.

• c# 4.0 - best way to refactor a block of "If (something is Type) {}" statements?

  - by Andrew Johns

  I've got some code that looks like this, public void ResetControls(Control controlOnPage) { if (controlOnPage is TextBox) { ResetTextBoxControl(controlOnPage); } if (controlOnPage is MediaPicker) { ((MediaPicker)controlOnPage).Media = null; } if (controlOnPage is RelatedContentPicker) { ((RelatedContentPicker)controlOnPage).RelatedContentCollection = null; } ... ... foreach (Control child in controlOnPage.Controls) { ResetControls(child); } } The idea behind it is that I can pass a page to the method and it'll recursively reset all the controls on it to their default states - in the case of MediaPicker and RelatedContentPicker, these are user controls that I've created. FXCop warns me "Do Not Cast Unnecessarily" for this code - but I'm unsure how to rewrite it to make it better. Any ideas?

• Silverlight and Active Directory Interaction

  - by Refracted Paladin

  I am planning to familiarize(read teach) myself with Silverlight by building an in-house app for managing our employees. I, obviously, would need this to interact with Active Directory on some level. What are my options? Has anyone tried this before? I am currently going to explore using Services(WCF???) to do the AD interaction portion? Thoughts? There is also this SO Post on using PowerShell to interact with AD. Maybe that is a possibility? Thanks, EDIT: Too clarify what I meant by "...interact with Active Directory..." I was referring to being able to create New Users, reset they're passwords, change they're Member Of groups, etc. Not JUST authenticating through AD. Does this make it clearer?
