  • what is the task of a coach in acm programming contests?

    - by Layla
    In the university that I am working they have decided to participate in the ACM regionals for the first time, they would like to appoint me like a coach. I have never been into that situation before and have not found so much information about it, so what is the real work of a coach in those contests? Sometimes I have found experienced programmers like coaches, but others are just people with no so good programming skills; so what is all about?

  • Is this a violation of the Liskov Substitution Principle?

    - by Paul T Davies
    Say we have a list of Task entities, and a ProjectTask sub type. Tasks can be closed at any time, except ProjectTasks which cannot be closed once they have a status of Started. The UI should ensure the option to close a started ProjectTask is never available, but some safeguards are present in the domain: public class Task { public Status Status { get; set; } public virtual void Close() { Status = Status.Closed; } } public ProjectTask : Task { public override void Close() { if (Status == Status.Started) throw new Exception("Cannot close a started Project Task"); base.Close(); } } Now when calling Close() on a Task, there is a chance the call will fail if it is a ProjectTask with the started status, when it wouldn't if it was a base Task. But this is the business requirements. It should fail. Can this be regarded as a violation?

  • Capistrano asks for SSH password when deploying from local machine to server

    - by GhostRider
    When I try to ssh to a server, I'm able to do it as my id_rsa.pub key is added to the authorized keys in the server. Now when I try to deploy my code via Capistrano to the server from my local project folder, the server asks for a password. I'm unable to understand what could be the issue if I'm able to ssh and unable to deploy to the same server. $ cap deploy:setup "no seed data" triggering start callbacks for `deploy:setup' * 13:42:18 == Currently executing `multistage:ensure' *** Defaulting to `development' * 13:42:18 == Currently executing `development' * 13:42:18 == Currently executing `deploy:setup' triggering before callbacks for `deploy:setup' * 13:42:18 == Currently executing `db:configure_mongoid' * executing "mkdir -p /home/deploy/apps/development/flyingbird/shared/config" servers: ["dev1.noob.com", "176.9.24.217"] Password: Cap script: # gem install capistrano capistrano-ext capistrano_colors begin; require 'capistrano_colors'; rescue LoadError; end require "bundler/capistrano" # RVM bootstrap # $:.unshift(File.expand_path('./lib', ENV['rvm_path'])) require 'rvm/capistrano' set :rvm_ruby_string, 'ruby-1.9.2-p290' set :rvm_type, :user # or :user # Application setup default_run_options[:pty] = true # allow pseudo-terminals ssh_options[:forward_agent] = true # forward SSH keys (this will use your SSH key to get the code from git repository) ssh_options[:port] = 22 set :ip, "dev1.noob.com" set :application, "flyingbird" set :repository, "repo-path" set :scm, :git set :branch, fetch(:branch, "master") set :deploy_via, :remote_cache set :rails_env, "production" set :use_sudo, false set :scm_username, "user" set :user, "user1" set(:database_username) { application } set(:production_database) { application + "_production" } set(:staging_database) { application + "_staging" } set(:development_database) { application + "_development" } role :web, ip # Your HTTP server, Apache/etc role :app, ip # This may be the same as your `Web` server role :db, ip, :primary => true # This is where Rails migrations will run # Use multi-staging require "capistrano/ext/multistage" set :stages, ["development", "staging", "production"] set :default_stage, rails_env before "deploy:setup", "db:configure_mongoid" # Uncomment if you use any of these databases after "deploy:update_code", "db:symlink_mongoid" after "deploy:update_code", "uploads:configure_shared" after "uploads:configure_shared", "uploads:symlink" after 'deploy:update_code', 'bundler:symlink_bundled_gems' after 'deploy:update_code', 'bundler:install' after "deploy:update_code", "rvm:trust_rvmrc" # Use this to update crontab if you use 'whenever' gem # after "deploy:symlink", "deploy:update_crontab" if ARGV.include?("seed_data") after "deploy", "db:seed" else p "no seed data" end #Custom tasks to handle resque and redis restart before "deploy", "deploy:stop_workers" after "deploy", "deploy:restart_redis" after "deploy", "deploy:start_workers" after "deploy", "deploy:cleanup" 'Create symlink for public uploads' namespace :uploads do task :symlink do run <<-CMD rm -rf #{release_path}/public/uploads && mkdir -p #{release_path}/public && ln -nfs #{shared_path}/public/uploads #{release_path}/public/uploads CMD end task :configure_shared do run "mkdir -p #{shared_path}/public" run "mkdir -p #{shared_path}/public/uploads" end end namespace :rvm do desc 'Trust rvmrc file' task :trust_rvmrc do run "rvm rvmrc trust #{current_release}" end end namespace :db do desc "Create mongoid.yml in shared path" task :configure_mongoid do db_config = <<-EOF defaults: &defaults host: localhost production: <<: *defaults database: #{production_database} staging: <<: *defaults database: #{staging_database} EOF run "mkdir -p #{shared_path}/config" put db_config, "#{shared_path}/config/mongoid.yml" end desc "Make symlink for mongoid.yml" task :symlink_mongoid do run "ln -nfs #{shared_path}/config/mongoid.yml #{release_path}/config/mongoid.yml" end desc "Fill the database with seed data" task :seed do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake db:seed" end end namespace :bundler do desc "Symlink bundled gems on each release" task :symlink_bundled_gems, :roles => :app do run "mkdir -p #{shared_path}/bundled_gems" run "ln -nfs #{shared_path}/bundled_gems #{release_path}/vendor/bundle" end desc "Install bundled gems " task :install, :roles => :app do run "cd #{release_path} && bundle install --deployment" end end namespace :deploy do task :start, :roles => :app do run "touch #{current_path}/tmp/restart.txt" end desc "Restart the app" task :restart, :roles => :app do run "touch #{current_path}/tmp/restart.txt" end desc "Start the workers" task :stop_workers do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake resque:stop_workers" end desc "Restart Redis server" task :restart_redis do "/etc/init.d/redis-server restart" end desc "Start the workers" task :start_workers do run "cd #{current_path}; RAILS_ENV=#{default_stage} bundle exec rake resque:start_workers" end end

  • Is it possible to use some form of code for example in PUTTY to execute a task which is done Remote

    - by xnxmx
    Basically, Every morning at 6:00AM I have to do login to remote desktop, open a program, and click on a few things to make reservations before anyone else does. I want to know if there is any other way that this can be done by simply turning it into some form of a code and executing it instead of manually doing it. Of course, time is precious here and the task needs to be done at the same pace if not faster. Thanks!!!

  • Where is the used memory in Task Manager & Resource Monitor coming from?

    - by Sam Adams
    On a Windows 7, the working set memory usage plus private memory does not add up to the total used memory in Task Manager and Windows 7 Resource Monitor. How do you find out where the used memory is coming from? The cached memory can't be part of it because sometimes the total cache is greater than the total in use. The commit memory plus the working set also doesn't add up to the total in use - but even that shouldn't be significant if it did, since commit is virtual.

  • How can I create a cron job that runs a task every three weeks?

    - by itj
    I have a task that needs to be performed on my project schedule (3 weeks). I'm able to set up cron to do this every week, or (for example) on the 3rd week of every month - but can't find a way to do this every three weeks. I could hack the script to create temporary files (or similar) so it could work out it was the third time it has been run - but this solution smells. Can it be done in a clean way?

  • Adding a new target type to msbuild: How do I refer to the itemname in the task rules?

    - by jmucchiello
    I'm trying to add a task to build the COM proxy DLL after building the main DLL. So I created the following in a .target file: <Target Name="ProxyDLL" Inputs="$(IntDir)%(WHATGOESHERE)_i.c;$(IntDir)dlldata.c" Outputs="$(OutDir)%(WHATGOESHERE)ps.dll" AfterTargets="Link"> <CL Sources="$(IntDir)%(WHATGOESHERE)_i.c;$(IntDir)dlldata.c" /> </Target> And reference it from the .vcxproj file as <ItemGroup> <ProxyDLL Include="FTAccountant" /> </ItemGroup> So the FTAccountant.DLL file is created through the normal build process and then when attempts to compile the proxy stubs it creates these command lines: cl /c dir\_i.c dir\dlldata.c And of course it can't find _i.c. The first attempt, I put %(Filename) in the WHATGOESHERE space and I got this error: C:\ActivePay\Build\Proxy DLL.targets(6,3): error MSB4095: The item metadata %(Filename) is being referenced without an item name. Specify the item name by using %(itemname.Filename). So I changed it to %(itemname.Filename) and that is an empty string. How to get the value specified in the task's Include attribute and use it within the task?

  • How to run a long task in backgroung in iOS applications?

    - by John Canady
    I am developing an application which requires running a task in background. I am trying this by calling a method which will retrieve(download) data from web server through web services. this method will call some more methods which are in different view controller classes. Here when I tap on home button of device, the method is calling but no further execution of the remaining code. This is the code I have written in (void)applicationDidEnterBackground:(UIApplication )application { UIApplication app = [UIApplication sharedApplication]; UIBackgroundTaskIdentifier bgTask = 0; bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; }]; // Start the long-running task and return immediately. dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ // Do the work associated with the task. NSString *updatekey = [[NSUserDefaults standardUserDefaults] objectForKey:@"updatesetting"]; if([updatekey isEqualToString:@"enabled"]) { DataSettingsView *periodicUpdate = [[DataSettingsView alloc] init]; [periodicUpdate updateDataPeriodically]; //[periodicUpdate viewDidLoad]; //[periodicUpdate release]; } [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; }); } some one please help me in this background execution of long tasks with some example of code. Some help will appreciated and helpful to me.

  • How to avoid concurrent execution of a time-consuming task without blocking?

    - by Diego V
    I want to efficiently avoid concurrent execution of a time-consuming task in a heavily multi-threaded environment without making threads wait for a lock when another thread is already running the task. Instead, in that scenario, I want them to gracefully fail (i.e. skip its attempt to execute the task) as fast as possible. To illustrate the idea considerer this unsafe (has race condition!) code: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing running = true; try { runExpensiveTask(); } finally { running = false; } } I though about using a variation of Double-Checked Locking (consider that running is a primitive 32-bit field, hence atomic, it could work fine even for Java below 5 without the need of volatile). It could look like this: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing synchronized (ThisClass.class) { if (running) return; running = true; try { runExpensiveTask(); } finally { running = false; } } } Maybe I should also use a local copy of the field as well (not sure now, please tell me). But then I realized that anyway I will end with an inner synchronization block, that still could hold a thread with the right timing at monitor entrance until the original executor leaves the critical section (I know the odds usually are minimal but in this case we are thinking in several threads competing for this long-running resource). So, could you think in a better approach?

  • Pivot Table grand total across columns

    - by Jon
    I'm using Excel 2010 and Power Pivot. I'm trying to calculate confidence and velocity for a development team. I'm extracting some information from our time and defect system each day and building a data set. What I need to do with Excel is do the calculations. So each day I add to my data set 1 row per task in the current project, estimate for that task and the time spent on that task. What I want to calculate is the estimate/actual for each task but also for each person. The trouble is that each day the actual is cumulative so I need to pick out the maximum value for each task. The estimate should remain unchanged. I can make this work at the task level with a calculated measure (=MAX(worked)/MAX(estimate)) but I don't know how to total this up for a person. I need the sum of the max worked for each task. So a dataset might look like: Name Task Estimate Worked N1 T1 3 1 N2 T2 3 1 N3 T3 4 1 N1 T1 3 2 N2 T4 5 1 N3 T3 4 2 N1 T5 1 2 N2 T6 2 3 N3 T7 3 2 What I want to see is for task T1 2 days were worked against an estimate of 3 days - so 2/3. For person N1 I want to see that they worked a total of 4 days against an estimate of 4 days so 4/4. For person N2 they worked 5 days for an estimate of 10 days. Any ideas on how I can achieve this?

  • Time to stop using &ldquo;Execute Package Task&rdquo;&ndash; a way to execute package in SSIS catalog taking advantage of the new project deployment model ,and the logging and reporting feature

    - by Kevin Shyr
    I set out to find a way to dynamically call package in SSIS 2012.  The following are 2 excellent blogs I found; I used them heavily.  The code below has some addition to parameter types and message types, but was made essentially derived entirely from the blogs. http://sqlblog.com/blogs/jamie_thomson/archive/2011/07/16/ssis-logging-in-denali.aspx http://www.ssistalk.com/2012/07/24/quick-tip-run-ssis-2012-packages-synchronously-and-other-execution-options/   The code: Every package will be called by a PackageController package.  The packageController is initialized with some information on which package to run and what information to pass in.   The following is the stored procedure called from the “Execute SQL Task”.  Here is the highlight of the stored procedure It takes in packageName, project name, and folder name (folder in SSIS project deployment to SSIS catalog) The stored procedure sets the package variables of the upcoming package execution Execute package in SSIS Catalog Get the status of the execution.  Also, if exists, get the error message’s message_id and store them in the management database.

  • Combining Scrum, TFS2010 and Email to keep everyone in the loop

    - by Martin Hinshelwood
    Often you will receive rich information from your Product Owner (Customer) about tasks. That information can be in the form of Word documents, HTML Emails and Pictures, but you generally receive them in the context of an Email. You need to keep these so your Team can refer to it later, and so you can send a “done” when the task has been completed. This preserves the “history” of the task and allows you to keep relevant partied included in any future conversation. At SSW we keep the original email so that we can reply Done and delete the email. But keeping it in your email does not help other members of the team if they complete the task and need to send the “done”. Worse yet, the description field in Team Foundation Server 2010 (TFS 2010) does not support HTML and images, nor does the default task template support an “interested parties” or CC field. You can attach this content manually, but it can be time consuming. Figure: Description only supports plain text, and History supports HTML with no images   What should we do? At SSW we always follow the rules, and it just so happened that we have rules to both achieve this, and to make it easier. You should follow the existing Rules to Better Project Management  and attach the email to your task so you can refer to and reply to it later when you close the task: Do you know what Outlook add-ins you need? Describe the work item request in an email Use Outlook Add-in to move the email to a TFS Work Item When replying to an email with “done” you should follow: Do you update Team Companion template, so the email "subject" doesn't change? Do you update Team Companion template, so you can generate a proper "done" mail? Following these simple rules will help your Product Owner understand you better, and allow your team to more effectively collaborate with each other. An added bonus is that as we are keeping the email history in sync with TFS. When you “reply all” to the email all of the interested partied to the Task are also included. This notified those that may have been blocked by your task to keep up to date with its status. This has been published as Do you know to ensure that relevant emails are attached to tasks in our Rules to Better Scrum using TFS. What could we do better? I would like to see this process automated so that we capture the information correctly in the task without the need to use email. This would require a change to the process template in Team Foundation Server to add an “Interested Parties” field. Each reply to the email would need to be automatically processed into a Work Item. This could be done by adding a task identifier as the first item in the “Relates to” email header, and copying in an email address that you watch. This would then parse out the relevant information and add the new message to the history, update the “Interested parties” field and attach the Images. Upon reflection, it may even be possible, but more difficult to do this using ONLY the History field and including some of the header information in there to the build a done email with history. This would not currently deal with email “forks” well, but I think it would be adequate for our needs. It would be nice if we could find time to implement this, but currently it is but a pipe dream. Maybe Microsoft could implement something in the next version of Team Foundation Server, and in the mean time we have a process that works well. Technorati Tags: Scrum,SSW Rules,TFS 2010,TFS 2008

  • The WaitForAll Roadshow

    - by adweigert
    OK, so I took for granted some imaginative uses of WaitForAll but lacking that, here is how I am using. First, I have a nice little class called Parallel that allows me to spin together a list of tasks (actions) and then use WaitForAll, so here it is, WaitForAll's 15 minutes of fame ... First Parallel that allows me to spin together several Action delegates to execute, well in parallel.   public static class Parallel { public static ParallelQuery Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery> Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery Task(this ParallelQuery actions, Action action) { var list = new List(actions); list.Add(action); return list.AsParallel(); } public static ParallelQuery> Task(this ParallelQuery> actions, Action action) { var list = new List>(actions); list.Add(action); return list.AsParallel(); } }   Next, this is an example usage from an app I'm working on that just is rendering some basic computer information via WMI and performance counters. The WMI calls can be expensive given the distance and link speed of some of the computers it will be trying to communicate with. This is the actual MVC action from my controller to return the data for an individual computer.  public PartialViewResult Detail(string computerName) { var computer = this.Computers.Get(computerName); var perf = Factory.GetInstance(); var detail = new ComputerDetailViewModel() { Computer = computer }; try { var work = Parallel .Task(delegate { // Win32_ComputerSystem var key = computer.Name + "_Win32_ComputerSystem"; var system = this.Cache.Get(key); if (system == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { system = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, system); } detail.TotalMemory = system.TotalPhysicalMemory; detail.Manufacturer = system.Manufacturer; detail.Model = system.Model; detail.NumberOfProcessors = system.NumberOfProcessors; }) .Task(delegate { // Win32_OperatingSystem var key = computer.Name + "_Win32_OperatingSystem"; var os = this.Cache.Get(key); if (os == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { os = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, os); } detail.OperatingSystem = os.Caption; detail.OSVersion = os.Version; }) // Performance Counters .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.AvailableBytes = perf.GetSample(computer, "Memory", "Available Bytes"); } }) .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.TotalProcessorUtilization = perf.GetValue(computer, "Processor", "% Processor Time", "_Total"); } }).WithExecutionMode(ParallelExecutionMode.ForceParallelism); if (!work.WaitForAll(TimeSpan.FromSeconds(15), task => task())) { return PartialView("Timeout"); } } catch (Exception ex) { this.LogException(ex); return PartialView("Error.ascx"); } return PartialView(detail); }

  • Walkthrough: Scheduling jobs using Quartz.net &ndash; Part 1: What is Quartz.Net?

    - by Tarun Arora
    Quartz.NET is a full-featured, open source enterprise job scheduling system written in .NET platform that can be used from smallest apps to large scale enterprise systems. What is the problem that we trying to address? I want to schedule the execution of a task but only when something happens. Let’s call that something a trigger, so... if the trigger is met => execute the task. Sounds simple, why not use windows task scheduler for this? Well, windows task scheduler is great for tasks where the trigger can be easily defined. With windows task scheduler will you be able to schedule a task to run on every working day according to the UK calendar (exclude all weekends & bank holidays) without either writing the logic for day check in the task or a wrapper script calling into the task. The task should just contain the execution logic and should not have anything to do with the schedule for execution; Quartz.net allows you to achieve this and lots more. A quartz.net trigger gives you the flexibility for task invocation based on the following triggers, 1. at a certain time of day (to the millisecond) 2. on certain days of the week 3. on certain days of the month 4. on certain days of the year 5. not on certain days listed within a registered Calendar (such as business holidays) 6. repeated a specific number of times 7. repeated until a specific time/date 8. repeated indefinitely 9. repeated with a delay interval Did 8 – repeat indefinitely just ring a bell? I’ll be covering that in the future post. Using Quartz.net as a windows service You can have Quartz.net run as a standalone instance within its own .NET virtual machine instance via .NET Remoting. Let’s take a look at typical application architecture. In the figure below, I have the application tier set up on Machine 1, database set up on Machine 2 and Quartz.net set up on Machine 3 which is normally the architecture for most (if not all) enterprise applications. Figure 1 -  Typical Application architecture while using Quartz.net as a windows service What other options do I have if I don’t want to use Quartz.net? Quartz.net is just one of the many job scheduling services. Have a look at this comprehensive list of free and paid enterprise job scheduling software along with their feature comparison. http://en.wikipedia.org/wiki/List_of_job_scheduler_software This was first in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering how to Install Quartz.net as a windows service.

  • Project Server 2007 Task Updates hangs on 'Loading Grid...'

    - by entens
    A strange problem began occurring after applying MOSS2 (KB953334) and the August 2009 cumulative update to our Project server. When a user enters the 'Task Update' screen they are prompted to download a new ActiveX control. Upon refresh, and subsequent access attempts, the user is presented with a blank grid with the caption 'Loading Grid...' We have attempted to fix this issue by updating the 'Trusted Sites' list and changing the security settings according to KB818046. However, nothing seems to definitely fix the problem. Also, when the problem randomly fixes itself, it still occurs when viewing specific projects. Any ideas on a fix?

  • System.Diaganostics.Process.Id Isn't the Same Process Id Shown in Task Manger. Why?

    - by LonnieBest
    I'm using c#'s System.Diagnostic.Process object. One of its properties is Id. The Id this produces is not the same as the PID, shown in Windows Task Manager. Why is this? You see, once this process is started. It launches two other unmanaged processes, for which I can't explicitly get IDs for by object property references. I have to search through all processes to find them by process name via System.Diagnostics.Process.GetProcesses(). I'm trying to find a reliable way to kill this process and all associated processes by PID, the one that shows in Task Manager. Is there a better way? I can't just kill all processes with the associated process names, because that might kill other instances of those processes that have nothing to do with my program.

  • How can I shrink the Address toolbar in the Task Bar?

    - by Iszi
    I like being able to run commands straight from my Task Bar. So, I've enabled the Address toolbar on my new Windows 7 system - just like I had on my old XP system. However, the bar seems to have a mandatory minimum length that's a bit longer than I'd prefer. It's about twice as long, if memory serves, as the minimum size allowed in XP. Is there any way I can adjust this minimum length, through a Registry key or some other means? (Note: I've also got a related question, about removing the Refresh button at the end of the bar.) EDIT: For clarity, I'm adding a screenshot. The toolbar I want to shorten is the one circled below, with an empty text-entry field that has a drop-down and "Refresh" button. I currently have it positioned between a Quick Launch toolbar and the Taskbar. On the far side of the Taskbar, before the System Tray, is a Desktop toolbar.
