  • Ruby on rails - Radrails IDE - mysql issues.

    - by ThomasReggi
    I have been trying to get Ruby on Rails to migrate a database for the good part of today, the problems all seem to result with this issue, can someone please help! If its a radrails specific problem I guess Ill take this to their forums. Something is telling me this is an easy fix. >rake db:migrate (in C:/Users/Thomas/My Documents/Aptana RadRails Workspace/rp) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! 126: The specified module could not be found. - C:/Ruby/lib/ruby/gems/1.8/gems/mysql-2.8.1-x86-mswin32/lib/1.8/mysql_api.so (See full trace by running task with --trace)

  • Hooking a Stacktrace in Delphi 2009

    - by Jim McKeeth
    The Exception class in Delphi 2009 received a number of new features. A number of them are related to getting a stacktrace: property StackTrace: string *read* GetStackTrace; property StackInfo: Pointer read FStackInfo; class var GetExceptionStackInfoProc: function (P: PExceptionRecord): Pointer; class var GetStackInfoStringProc: function (Info: Pointer): string; class var CleanUpStackInfoProc: procedure (Info: Pointer); Has anyone used these to obtain a stack trace yet? Yeah, I know there are other ways to get a stack trace, but if it is supported natively in the Exception class I would rather leverage that. Update: There is an interest blog post about this. Covers it in a lot of depth.

  • Bacula & Multiple Tape Devices, and so on

    - by Tom O'Connor
    Bacula won't make use of 2 tape devices simultaneously. (Search for #-#-# for the TL;DR) A little background, perhaps. In the process of trying to get a decent working backup solution (backing up 20TB ain't cheap, or easy) at $dayjob, we bought a bunch of things to make it work. Firstly, there's a Spectra Logic T50e autochanger, 40 slots of LTO5 goodness, and that robot's got a pair of IBM HH5 Ultrium LTO5 drives, connected via FibreChannel Arbitrated Loop to our backup server. There's the backup server.. A Dell R715 with 2x 16 core AMD 62xx CPUs, and 32GB of RAM. Yummy. That server's got 2 Emulex FCe-12000E cards, and an Intel X520-SR dual port 10GE NIC. We were also sold Commvault Backup (non-NDMP). Here's where it gets really complicated. Spectra Logic and Commvault both sent respective engineers, who set up the library and the software. Commvault was running fine, in so far as the controller was working fine. The Dell server has Ubuntu 12.04 server, and runs the MediaAgent for CommVault, and mounts our BlueArc NAS as NFS to a few mountpoints, like /home, and some stuff in /mnt. When backing up from the NFS mountpoints, we were seeing ~= 290GB/hr throughput. That's CRAP, considering we've got 20-odd TB to get through, in a <48 hour backup window. The rated maximum on the BlueArc is 700MB/s (2460GB/hr), the rated maximum write speed on the tape devices is 140MB/s, per drive, so that's 492GB/hr (or double it, for the total throughput). So, the next step was to benchmark NFS performance with IOzone, and it turns out that we get epic write performance (across 20 threads), and it's like 1.5-2.5TB/hr write, but read performance is fecking hopeless. I couldn't ever get higher than 343GB/hr maximum. So let's assume that the 343GB/hr is a theoretical maximum for read performance on the NAS, then we should in theory be able to get that performance out of a) CommVault, and b) any other backup agent. Not the case. Commvault seems to only ever give me 200-250GB/hr throughput, and out of experimentation, I installed Bacula to see what the state of play there is. If, for example, Bacula gave consistently better performance and speeds than Commvault, then we'd be able to say "**$.$ Refunds Plz $.$**" #-#-# Alas, I found a different problem with Bacula. Commvault seems pretty happy to read from one part of the mountpoint with one thread, and stream that to a Tape device, whilst reading from some other directory with the other thread, and writing to the 2nd drive in the autochanger. I can't for the life of me get Bacula to mount and write to two tape drives simultaneously. Things I've tried: Setting Maximum Concurrent Jobs = 20 in the Director, File and Storage Daemons Setting Prefer Mounted Volumes = no in the Job Definition Setting multiple devices in the Autochanger resource. Documentation seems to be very single-drive centric, and we feel a little like we've strapped a rocket to a hamster, with this one. The majority of example Bacula configurations are for DDS4 drives, manual tape swapping, and FreeBSD or IRIX systems. I should probably add that I'm not too bothered if this isn't possible, but I'd be surprised. I basically want to use Bacula as proof to stick it to the software vendors that they're overpriced ;) I read somewhere that @KyleBrandt has done something similar with a modern Tape solution..

  • Disable caching in JPA (eclipselink)

    - by James
    Hi, I want to use JPA (eclipselink) to get data from my database. The database is changed by a number of other sources and I therefore want to go back to the database for every find I execute. I have read a number of posts on disabling the cache but this does not seem to be working. Any ideas? I am trying to execute the following code: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one==two); one==two is true while I want it to be false. I have tried adding each/all the following to my persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.cache.size.default" value="0"/> <property name="eclipselink.cache.type.default" value="None"/> I have also tried adding the @Cache annotation to the Entity itself: @Cache( type=CacheType.NONE, // Cache nothing expiry=0, alwaysRefresh=true ) Am I misunderstanding something? Thank you, James

    I have a wcf webservice on one of my testing servers. Everything worked fine until I upgraded frome framework 3.5 to 3.5 sp1. the wcf web service stoped working and returns the error: "Failed to invoke the service.

  • Change CulturalInfo after button click

    - by Bart
    i have multilingual asp.net site. there is masterpage and default.aspx in masterpage i put two buttons one to click when i want to change the language to english, second for polish. I want to change the language after click on these buttons (and all changes should appear automatically on the page) here is a code for both: protected void EnglishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "en-US"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } protected void PolishButton_Click(object sender, ImageClickEventArgs e) { string selectedLanguage = "pl-PL"; //Sets the cookie that is to be used by InitializeCulture() in content page HttpCookie cookie = new HttpCookie("CultureInfo"); cookie.Value = selectedLanguage; Response.Cookies.Add(cookie); Server.Transfer(Request.Path); } in default.aspx.cs i have InitializeCulture(): protected override void InitializeCulture() { HttpCookie cookie = Request.Cookies["CultureInfo"]; // if there is some value in cookie if (cookie != null && cookie.Value != null) { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(cookie.Value); Thread.CurrentThread.CurrentUICulture = new CultureInfo(cookie.Value); } else // if none value has been sent by cookie, set default language { Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture("pl-PL"); Thread.CurrentThread.CurrentUICulture = new CultureInfo("pl-PL"); } base.InitializeCulture(); } i added resource files and in one label i show actual culture: Welcome.Text = "Culture: " + System.Globalization.CultureInfo.CurrentCulture.ToString(); the problem is that when i run this app and click e.g. english button (default language is polish), there is no effect. if i click it second time or press F5, the changes are applies and in the label is Culture: en-US. the same happens if i want to change language back to polish (it works after second click (or one click and refresh)). What am i doing wrong?

    I am trying to get Uploadify working with Rails 3. However, I can't insert the middleware with the correct arguments. This is the Rails 2 way: ActionController::Dispatcher.middleware.insert_before( ActionController::Session::CookieStore, FlashSessionCookieMiddleware, ActionController::Base.session_options[:key] ) This is what I have so far for Rails 3: Rails.application.config.middleware.insert_before( Rails.application.config.session_store, FlashSessionCookieMiddleware, Rails.application.config.session_options[:key] ) However, this gives: kevin$hephaestus:$exposure [1035 | 0]% rake middleware (in /Users/kevin/Projects/exposure) rake aborted! protected method `session_options' called for #<Rails::Application::Configuration:0x101eb28d0> (See full trace by running task with --trace) zsh: exit 1 rake middleware When I comment out the session_options argument, the middleware is successfully inserted, but it can't do what it is supposed to.

  • inbound/outbound url routing in asp.net MVC

    - by Stephane
    The routing I need is quite simple, I must be missing something there. As code example I put the simpler situation where I can reproduce my behavior. You have this ActionMethod : public ActionResult Index(string provider) { ViewData["Message"] = provider; return View("Index"); } And you have this route : routes.MapRoute( null, "{controller}/{action}/{provider}", new { controller = "Home", action = "Index", provider = "Default" } ); // Parameter defaults You can call /Home/Index/Custom and provider will take the value "Custom" What Route would I need if I want the url /?provider=Custom to map the provider to the parameter. I thought that would just work, because the default controller and the default action would be used, and the provider from the querystring would be used instead of the default one. but the querystring is just ignored here. That's a problem in my situation as I have a form using HTTP GET method. The form action has to be Html.BeginForm(c=c.Index(null)) which is resolved as / and the value of my form are added in the querystring. (the provider being a dropdown in the form) So the url built by the form is /?abc=value&cde=value...

  • Returning errors from AMFPHP on purpose.

    - by Morieris
    When using flash remoting with amfphp, what can I write in php that will trigger the 'status' method that I set up in my Responder in Flash? Or more generally, how can I determine if the service call has failed? The ideal solution for me would be to throw some exception in php serverside, and catch that exception in flash clientside... How do other people handle server errors with flash remoting? var responder = new Responder( function() { trace("some normal execution finished successfully. this is fine."); }, function(e) { trace("how do I make this trigger when my server tells me something bad happened?"); } ); myService = new NetConnection; myService.connect("http://localhost:88/amfphp/gateway.php"); myService.call("someclass.someservice", responder);

  • Why is my sound not working in Flash?

    - by animuson
    This is what I have as far as code, it is in the first frame of the movie. nature = new Sound(this); nature.attachSound("sound_naturally"); nature.setVolume(50); nature.start(0,0); nature.onSoundComplete = function(){ nature.start(0,0); } trace(nature); The trace outputs '[object Object]' at runtime. I have the sound exporting to ActionScript with the link identifier 'sound_naturally', not exported to the first frame. I don't understand why it's not working. I did like the exact same thing like 3 hours ago and it worked fine, but I lost the file so I had to redo it and now it won't work at all. Using Flash 10 with ActionScript 2.0

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works.

  • How do I run a ruby script, that I put in my /lib/tasks/ directory in my Rails app, once?

    - by marcamillion
    Eventually I would like to get to setting it up as a Rake task and do a cron job, but for right now...all I want to do is take my ruby script that used to work as a standalone script and have it work within my Rails app. I renamed the file to be .rake instead of .rb and tried doing rake my_script at the command-line, but that gave me this error message: rake aborted! Don't know how to build task 'my_script' (See full trace by running task with --trace) How do I run this script within my Rails environment? This is the first time I am doing something like this, so any assistance would be greatly appreciated. Thanks.

  • Adding info to an exception

    - by NoozNooz42
    I'd like to add information to a stack trace/exception. Basically I've got something like this as of now, which I really like: Exception in thread "main" java.lang.ArithmeticException: / by zero at com.so.main(SO.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke However I'd like to catch that exception and add additional info to it, while still having the original stack trace. For example, I'd like to have that: Exception in thread "main" CustomException: / by zero (you tried to divide 42 by 0) at com.so.main(SO.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke So basically I want to catch the ArithmeticException and rethrow, say, a CustomException (adding "you tried to divide 42 by 0" in this example) while still keeping the stacktrace from the original ArithmeticException. What is the correct way to do this in Java? Is the following correct: try { .... } catch (ArithmeticException e) { throw new CustomException( "You tried to divide " + x + " by " + y, e ); }

  • Can I copy/clone a function in JavaScript?

    - by Craig Stuntz
    I'm using jQuery with the validators plugin. I would like to replace the "required" validator with one of my own. This is easy: jQuery.validator.addMethod("required", function(value, element, param) { return myRequired(value, element, param); }, jQuery.validator.messages.required); So far, so good. This works just fine. But what I really want to do is call my function in some cases, and the default validator for the rest. Unfortunately, this turns out to be recursive: jQuery.validator.addMethod("required", function(value, element, param) { // handle comboboxes with empty guids if (someTest(element)) { return myRequired(value, element, param); } return jQuery.validator.methods.required(value, element, param); }, jQuery.validator.messages.required); I looked at the source code for the validators, and the default implementation of "required" is defined as an anonymous method at jQuery.validator.messages.required. So there is no other (non-anonymous) reference to the function that I can use. Storing a reference to the function externally before calling addMethod and calling the default validator via that reference makes no difference. What I really need to do is to be able to copy the default required validator function by value instead of by reference. But after quite a bit of searching, I can't figure out how to do that. Is it possible? If it's impossible, then I can copy the source for the original function. But that creates a maintenance problem, and I would rather not do that unless there is no "better way."

  • Python, dictionaries, and chi-square contingency table

    - by rohanbk
    I have a file which contains several lines in the following format (word, time that the word occurred in, and frequency of documents containing the given word within the given instance in time): #inputfile <word, time, frequency> apple, 1, 3 banana, 1, 2 apple, 2, 1 banana, 2, 4 orange, 3, 1 I have Python class below that I used to create 2-D dictionaries to store the above file using as the key, and frequency as the value: class Ddict(dict): ''' 2D dictionary class ''' def __init__(self, default=None): self.default = default def __getitem__(self, key): if not self.has_key(key): self[key] = self.default() return dict.__getitem__(self, key) wordtime=Ddict(dict) # Store each inputfile entry with a <word,time> key timeword=Ddict(dict) # Store each inputfile entry with a <time,word> key # Loop over every line of the inputfile for line in open('inputfile'): word,time,count=line.split(',') # If <word,time> already a key, increment count try: wordtime[word][time]+=count # Otherwise, create the key except KeyError: wordtime[word][time]=count # If <time,word> already a key, increment count try: timeword[time][word]+=count # Otherwise, create the key except KeyError: timeword[time][word]=count The question that I have pertains to calculating certain things while iterating over the entries in this 2D dictionary. For each word 'w' at each time 't', calculate: The number of documents with word 'w' within time 't'. (a) The number of documents without word 'w' within time 't'. (b) The number of documents with word 'w' outside time 't'. (c) The number of documents without word 'w' outside time 't'. (d) Each of the items above represents one of the cells of a chi-square contingency table for each word and time. Can all of these be calculated within a single loop or do they need to be done one at a time? Ideally, I would like the output to be what's below, where a,b,c,d are all the items calculated above: print "%s, %s, %s, %s" %(a,b,c,d)

If I have machine with native IE6 running chrome frame click the TEST button, I receive: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Default.aspx I have tried this test on an IIS 7 host and several other IE6 machines with the same result. What I have noticed is that it is trying to postback to the wrong URL. I have checked with fiddler and have seen it will start at hostname/test/default.aspx but when I click the button it is trying to post to hostname/default.aspx Any help is greatly appreciated.

  • How to View Android Native Code Profiling?

    - by David R.
    I started my emulator with ./emulator -trace profile -avd emulator_15. I then tracked down the trace files to ~/.android/avd/rodgers_emulator_15.avd/traces/profile, where there are six files: qtrace.bb, qtrace.exc, qtrace.insn, qtrace.method, qtrace.pid, qtrace.static. I can't figure out what to do with these files. I've tried both dmtracedump and traceview on all of the files, but none seem to generate any output I can do anything with. How can I view the proportion of time taken by native method calls on Android?

  • Cap deploy doesn't work all the sudden; something to do with FactoryGirl and assets

    - by Jason Swett
    I've been cap deploying my app all throughout it development, and this last time I tried to deploy it, it didn't work. Here's what happened: * executing `deploy:assets:precompile' * executing "cd /var/www/oneteam/releases/20121006153136 && bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile" servers: ["electricsasquatch.com"] [electricsasquatch.com] executing command ** [out :: electricsasquatch.com] rake aborted! ** [out :: electricsasquatch.com] uninitialized constant OneTeam::Application::FactoryGirl ** [out :: electricsasquatch.com] ** [out :: electricsasquatch.com] (See full trace by running task with --trace) It looks like it failed on the deploy:assets:precompile command. I don't get why that command would have tried to do anything with FactoryGirl, though. Any ideas?

  • Disable chaching in JPA (eclipselink)

    - by James
    Hi, I want to use JPA (eclipselink) to get data from my database. The database is changed by a number of other sources and I therefore want to go back to the database for every find I execute. I have read a number of posts on disabling the cache but this does not seem to be working. Any ideas? I am trying to execute the following code: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one==two); one==two is true while I want it to be false. I have tried adding each/all the following to my persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.cache.size.default" value="0"/> <property name="eclipselink.cache.type.default" value="None"/> I have also tried adding the @Cache annotation to the Entity itself: @Cache( type=CacheType.NONE, // Cache nothing expiry=0, alwaysRefresh=true ) Am I misunderstanding something? Thank you, James
