  • PHP Localization Best Practices? gettext?

    - by nute
    We are in the process of making our website international, allowing multiple languages. I've looked into php's "gettext" however, if I understand it right, I see a big flaw: If my webpage has let's say "Hello World" as a static text. I can put the string as <?php echo gettext("Hello World"); ?>, generate the po/mo files using a tool. Then I would give the file to a translator to work on. A few days later we want to change the text in English to say "Hello Small World"? Do I change the value in gettext? Do I create an english PO file and change it there? If you change the gettext it will consider it as a new string and you'll instantly loose the current translation ... It seems to me that gradually, the content of the php file will have old text everywhere. Or people translating might have to be told "when you see Hello World, instead, translate Hello Small World". I don't know I'm getting confused. In other programming languages, I've seen that they use keywords such as web.home.featured.HelloWorld. What is the best way to handle translations in PHP? Thanks

  • How to test an HTTP 301 redirect?

    - by NoozNooz42
    How can one easily test HTTP return codes, like, say, a 301 redirect? For example, if I want to "see what's going on", I can use telnet to do something like this: ... $ telnet nytimes.com 80 Trying 199.239.136.200... Connected to nytimes.com. Escape character is '^]'. GET / HTTP/1.0 (enter) (enter) HTTP/1.1 200 OK Server: Sun-ONE-Web-Server/6.1 Date: Mon, 14 Jun 2010 12:18:04 GMT Content-type: text/html Set-cookie: RMID=007af83f42dd4c161dfcce7d; expires=Tuesday, 14-Jun-2011 12:18:04 GMT; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Set-cookie: adxcs=-; path=/; domain=.nytimes.com Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-control: no-cache Pragma: no-cache Connection: close <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> ... Which is an easy way to access quite some infos. But now I want to test that a 301 redirect is indeed a 301 redirect. How can I do so? Basically, instead of getting a HTTP/1.1 200 OK I'd like to know how I can get the 301? I know that I can enter the name of the URL in a browser and "see" that I'm redirected, but I'd like to know what tool(s) can be used to actually really "see" the 301 redirect. Btw, I did test with a telnet, but when I enter www.example.org, which I redirected to example.org (without the www), all I can see is an "200 OK", I don't get to see the 301.

  • Jenkins slave jobs failing on "Unexpected termination of channel"

    - by Clark Wright
    I am currently seeing a set of errors across my builds. Is this expected behaviour if you loose Jenkins (say to a box crash, or a kill -9)? Or is there something worse going on (like a bad network connection)? The stack and error is: FATAL: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel hudson.remoting.RequestAbortedException: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.call(Request.java:149) at hudson.remoting.Channel.call(Channel.java:681) at hudson.remoting.RemoteInvocationHandler.invoke(RemoteInvocationHandler.java:158) at $Proxy175.join(Unknown Source) at hudson.Launcher$RemoteLauncher$ProcImpl.join(Launcher.java:861) at hudson.Launcher$ProcStarter.join(Launcher.java:345) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:82) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:703) at hudson.model.Build$RunnerImpl.build(Build.java:178) at hudson.model.Build$RunnerImpl.doRun(Build.java:139) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:473) at hudson.model.Run.run(Run.java:1410) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:238) Caused by: hudson.remoting.RequestAbortedException: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Request.abort(Request.java:273) at hudson.remoting.Channel.terminate(Channel.java:732) at hudson.remoting.Channel$ReaderThread.run(Channel.java:1157) Caused by: java.io.IOException: Unexpected termination of the channel at hudson.remoting.Channel$ReaderThread.run(Channel.java:1133) Caused by: java.io.EOFException at java.io.ObjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2554) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1297) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:351) at hudson.remoting.Channel$ReaderThread.run(Channel.java:1127)

  • Flash video slooow in AIR 2 HTMLLoader component

    - by shane
    I am working on a full screen kiosk application in Flex 4/Air 2 using Flash Builder 4. We have a company training website which staff can access via the kiosk, and the main content is interactive flash training videos. Our target machines are by no means 'beefy', they are Atom n270s @ 1.6Ghz with 1Gb RAM. As it stands the videos are all but unusable when used from within the Air application, the application becomes completely unresponsive (100% cpu usage, click events take approx 5-10 seconds to register). So far I have tried: increasing the default frame rate from 24fps to 60. No improvement. nativeWindow.stage.frameRate = 60; running the videos in a stripped down version of my app, just a full screen HTMLLoader component pointed at the training website. No better than before. disabled hyper threading. The Atom CPU is split into two virtual cores, and the AIR app was only able to use one thread so maxed out at 50% CPU usage. Since the kiosk will only run the AIR app I am happy to loose hyper threading to increase the performance of the Air app. Marginal Improvement. The same website with the same videos is responsive if viewed in ie7 on the same machine, although Internet Explorer takes advantage of the CPU’s hyper threading. The flash videos are built with Adobe Captivate and from what I understand employee JavaScript to relay results back to the server. I will add more information about the video content asap as the training guru is back in the office later this week.

  • Rails, RSpec and Webrat: Expected output matches rendered output but still getting error in view spe

    - by Anthony Burns
    Hello all, I've just gotten started using BDD with RSpec/Cucumber/Webrat and Rails and I've run into some frustration trying to get my view spec to pass. First of all, I am running Ruby 1.9.1p129 with Rails 2.3.2, RSpec and RSpec-Rails 1.2.6, Cucumber 0.3.11, and Webrat 0.4.4. Here is the code relevant to my question config/routes.rb: map.b_posts 'backend/posts', :controller => 'backend/posts', :action => 'backend_index', :conditions => { :method => :get } map.connect 'backend/posts', :controller => 'backend/posts', :action => 'create', :conditions => { :method => :post } views/backend/posts/create.html.erb: <% form_tag do %> <% end %> *spec/views/backend/posts/create.html.erb_spec.rb:* describe "backend/posts/create.html.erb" do it "should render a form to create a post" do render "backend/posts/create.html.erb" response.should have_selector("form", :method => 'post', :action => b_posts_path) do |form| # Nothing here yet. end end end Here is the relevant part of the output when I run script/spec: 'backend/posts/create.html.erb should render a form to create a post' FAILED expected following output to contain a <form method='post' action='/backend/posts'/> tag: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><form action="/backend/posts" method="post"> </form></body></html> It would appear to me that what have_selector is looking for is exactly what the template generates, yet the example still fails. I am very much looking forward to seeing my error (because I have a feeling it is my error). Any help is much appreciated!

  • How do I create a multi-level TreeView using F#?

    - by TwentyMiles
    I would like to display a directory structure using Gtk# widgets through F#, but I'm having a hard time figuring out how to translate TreeViews into F#. Say I had a directory structure that looks like this: Directory1 SubDirectory1 SubDirectory2 SubSubDirectory1 SubDirectory3 Directory2 How would I show this tree structure with Gtk# widgets using F#? EDIT: gradbot's was the answer I was hoping for with a couple of exceptions. If you use ListStore, you loose the ability to expand levels, if you instead use : let musicListStore = new Gtk.TreeStore([|typeof<String>; typeof<String>|]) you get a layout with expandable levels. Doing this, however, breaks the calls to AppendValues so you have to add some clues for the compiler to figure out which overloaded method to use: musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) Note that the columns are explicitly passed as an array. Finally, you can nest levels even further by using the ListIter returned by Append Values let iter = musicListStore.AppendValues ("Dance") let subiter = musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) musicListStore.AppendValues (subiter, [|"Some Dude"; "Some Song"|]) |> ignore

  • Heroku taps push weirdness...

    - by holden
    I have the strangest experience using taps to move data between my machine and heroku. It works fine except that it seems to loose 0s directly behind the decimal place for my geo coordinates. Ie 50.0519322 for some reason gets set to 50.519322... no idea why. When I pull the data from the remote location ie. heroku db:pull... it works fine, all decimal places intact on my machine, however, when i push it back to the remote server it loses these zeros. Especially directly behind the decimal place, though I haven't noticed it elsewhere yet. At first I was storing the lat and lng as simply numeric but refined it to: change_column :places, :lat, :numeric, :precision => 15, :scale => 10 change_column :places, :lng, :numeric, :precision => 15, :scale => 10 With no result, any ideas what's going on? From the console on the remote server i get the lat as being: #<BigDecimal:2aebcc5967c0,'0.50519322E2',18(18)> and my machine as: #<BigDecimal:10232f7c8,'0.50519322E2',12(16)> which is also odd, the second one because it shows up as 50.0519322 when i edit it thru my view but when i do to_f via console it gives me 50.519322

  • Weblogic 10.3.0 : Loosing a stateless session bean in the bean pool

    - by KlasE
    Hi, We have a strange situation where we loose a Stateless SessionBean in a Bean Pool in Weblogic 10.3.0 Since we only have one bean in the pool, this effectively hangs all incoming calls. We do not want more than one instance in the pool because of application restrictions. In the Weblogic admin console, we can see that there are 1 instance in the bean pool, 0 beans in use and 1 waiting incoming request. The question is, what can have caused the system to not send the request to the one obviously free bean instance? This happens after several hours and over 100000 incoming requests, and the same scenario worked fine in the old weblogic 8 environment. We get the following stacktrace: "[ACTIVE] ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)'" waiting for lock java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject@b0d484 TIMED_WAITING sun.misc.Unsafe.park(Native Method) java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:198) java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2054) weblogic.ejb.container.pool.StatelessSessionPool.waitForBean(StatelessSessionPool.java:269) weblogic.ejb.container.pool.StatelessSessionPool.getBean(StatelessSessionPool.java:111) weblogic.ejb.container.manager.StatelessManager.preInvoke(StatelessManager.java:148) weblogic.ejb.container.internal.BaseRemoteObject.preInvoke(BaseRemoteObject.java:227) weblogic.ejb.container.internal.StatelessRemoteObject.preInvoke(StatelessRemoteObject.java:52) com.mycompany.beans.MessageLogFacace_n73y0z_EOImpl.isMyStuffValid(MessageLogFacace_n73y0z_EOImpl.java:261) com.mycompany.beans.MessageLogFacace_n73y0z_EOImpl_WLSkel.invoke(Unknown Source) weblogic.rmi.internal.BasicServerRef.invoke(BasicServerRef.java:589) weblogic.rmi.cluster.ClusterableServerRef.invoke(ClusterableServerRef.java:230) weblogic.rmi.internal.BasicServerRef$1.run(BasicServerRef.java:477) weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:363) weblogic.security.service.SecurityManager.runAs(Unknown Source) weblogic.rmi.internal.BasicServerRef.handleRequest(BasicServerRef.java:473) weblogic.rmi.internal.wls.WLSExecuteRequest.run(WLSExecuteRequest.java:118) weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) weblogic.work.ExecuteThread.run(ExecuteThread.java:173) Any help would be very welcome.

  • add new option to dropdownlist after jquery dialog and post

    - by RememberME
    I have a form to enter subcontracts. On this form I have a dropdownlist of all companies in the system. Next to it is a button "Create Company". This button opens a jquery dialog which allows the user to create a new company. Once the dialog closes, the new company needs to be added to the dropdownlist and selected. If I refresh, it's there, but I need to do it without refreshing the form b/c I don't want the user to loose everything that they've entered into the other fields. I'm not sure how to do this b/c I don't have the guid of the new company. My jquery dialog: $('#popupCreateCompany').dialog( { autoOpen: false, modal: true, buttons: { 'Add': function() { var dialog = $(this); var form = dialog.find('input:text, select'); $.post('/company/create', $(form).serialize(), function() { dialog.dialog('close'); }) }, 'Cancel': function() { $(this).dialog('close'); } } }); $("#create-company").click(function() { $('#popupCreateCompany').dialog('open'); }); Company field: <label for="company">Company:</label> <%= Html.DropDownList("company", Model.SelectCompanies, "** Select Company **") %> <%= Html.ValidationMessage("Company", "*") %> <button type="button" id="create-company" >Create Company</button>

  • How to limit traffic using multicast over localhost

    - by Shane Holloway
    I'm using multicast UDP over localhost to implement a loose collection of cooperative programs running on a single machine. The following code works well on Mac OSX, Windows and linux. The flaw is that the code will receive UDP packets outside of the localhost network as well. For example, sendSock.sendto(pkt, ('192.168.0.25', 1600)) is received by my test machine when sent from another box on my network. import platform, time, socket, select addr = ("239.255.2.9", 1600) sendSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_TTL, 24) sendSock.setsockopt(socket.IPPROTO_IP, socket.IP_MULTICAST_IF, socket.inet_aton("127.0.0.1")) recvSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP) recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True) if hasattr(socket, 'SO_REUSEPORT'): recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEPORT, True) recvSock.bind(("0.0.0.0", addr[1])) status = recvSock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, socket.inet_aton(addr[0]) + socket.inet_aton("127.0.0.1")); while 1: pkt = "Hello host: {1} time: {0}".format(time.ctime(), platform.node()) print "SEND to: {0} data: {1}".format(addr, pkt) r = sendSock.sendto(pkt, addr) while select.select([recvSock], [], [], 0)[0]: data, fromAddr = recvSock.recvfrom(1024) print "RECV from: {0} data: {1}".format(fromAddr, data) time.sleep(2) I've attempted to recvSock.bind(("127.0.0.1", addr[1])), but that prevents the socket from receiving any multicast traffic. Is there a proper way to configure recvSock to only accept multicast packets from the 127/24 network, or do I need to test the address of each received packet?

  • embedded php in html to include header (top part of page) into the page

    - by Andy
    Hi there, I'm trying to put the top of my page (which is all html) in a seperate file so I only need to change things once like the menu bar etc. So I googled some and found a solution on this website as well, but it doesn't work and I don't know why. So I have a page like article.html and on the top I have this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <?php include("/pages/header.php"); ?> <!-- rest of the html code --> In the header.php I have the html that should be on the top of each page and it starts with: <?php /** * @author name * website header */ ?> <!-- html code --> So what's wrong with this. When I open the page article.html and right click on it to view the source, I can see the php from above calling the header.php file. Thanks!

  • In git, how can I get the diff between two dates?

    - by Weidenrinde
    Basically, I am looking for something equivalent to cvs diff -D"1 day ago" -D"2010-02-29 11:11". While collecting more and more information, I found a solution. I paste it here, for others that might have similar problems. Things I have tried: In git, how can I get the diff between all the commits that occured between two dates? was ansered here with: git whatchanged --since="1 day ago" -p But this gives a diff for each commit, even if there are multiple commits in one file. I know that "date" is a bit of a loose concept in git, I thought there must be some way to do this. git diff 'master@{1 day ago}..master gives some warning warning: Log for 'master' only goes back to Tue, 16 Mar 2010 14:17:32 +0100. and does not show old diffs. git format-patch --since=yesterday --stdout does not give anything. revs=$(git log --pretty="format:%H" --since="1 day ago");git diff $(echo "$revs"|tail -n1) $(echo "$revs"|head -n1) works somehow, but seems complicated and does not restrict to the current branch. git diff $(git rev-list -n1 --before="1 day ago" master) seems to work and a default way to do similar things, although more complicated than I thought. Funnily, git-cvsserver does not support "cvs diff -D" (without that it is documented somewhere).

  • PHP (A few questions) OO, refactoring, eclipse

    - by jax
    I am using PHP in eclipse. It works ok, I can connect to my remote site, there is colour coding of code elements and some code hints. I realise this may be too long to answer all questions, if you have a good answer for one part, answering just that is ok. Firstly General Coding I have found that it is easy to loose track of included files and their variables. For example if there was a database $cursor it is difficult to remember or even know that it was declared in the included file (this becomes much worse the more files you include). How are people dealing with this? How are people documenting their code - in particular the required GET and POST data? Secondly OO Development: Should I be going full OO in my development. Currently I have a functions library which I can include and have separated each "task" into a separate file. It is a bit nasty but it works. If I go OO how do I structure the directories in PHP, java uses packages - what about php? How should I name my files, should I use all lower case with _ for spaces "hello_world.php"? Should I name classes with Uppercase like Java "HelloWorld.php"? Is there a different naming convention for Classes and regular function files? Thirdly Refactoring I must say this is a real pain. If I change the name of a variable in one place I have to go through whole document and each file that included this file and change the name their too. Of course, errors everywhere is what results. How are people dealing with this problem? In Java if you change the name in one place it changes everywhere. Are there any plugins to improve php refactoring? I am using the official PHP version of Eclipse from their website. thanks

  • Delphi - Populate an imagelist with icons at runtime 'destroys' transparency

    - by ben
    Hi again, I've spended hours for this (simple) one and don't find a solution :/ I'm using D7 and the TImageList. The ImageList is assigned to a toolbar. When I populate the ImageList at designtime, the icons (with partial transparency) are looking fine. But I need to populate it at runtime, and when I do this the icons are looking pretty shitty - complete loose of the partial transparency. I just tried to load the icons from a .res file - with the same result. I've tried third party image lists also without success. I have no clue what I could do :/ Thanks 2 all ;) edit: To be honest I dont know exactly whats going on. Alpha blending is the correkt term... Here are 2 screenies: Icon added at designtime: Icon added at runtime: Your comment that alpha blending is not supported just brought the solution: I've edited the image in an editor and removed the "alpha blended" pixels - and now it looks fine. But its still strange that the icons look other when added at runtime instead of designtime. If you (or somebody else ;) can explain it, I would be happy ;) thanks for you support!

  • Programatic re-evalutation of MVVM command's "can execute" state

    - by dzs
    Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

  • JS encodeURIComponent result different from the one created by FORM

    - by Marco Demaio
    I thought values entered in forms are properly encoded by browsers. But this simple test shows it's not true: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title></title> </head><body> <form id="test" action="test_get_vs_encodeuri.html" method="GET" onsubmit="alert(encodeURIComponent(this.one.value));"> <input name="one" type="text" value="Euro-€"> <input type="submit" value="SUBMIT"> </form> </body></html> When hitting submit button: encodeURICompenent encodes input value into "Euro-%E2%82%AC" while browser into the GET query writes only a simple "Euro-%80" Could somone explain? Or is encodeURIComponent doing unnecessary conversions?

  • Entity Framework - Foreign key constraints not added for inherited entity

    - by Tri Q
    Hello, It appears to me that a strange phenomenon is occurring with inherited entities (TPT) in EF4. I have three entities. 1. Asset 2. Property 3. Activity Property is a derived-type of Asset. Property has many activities (many-to-many) When modeling this in my EDMX, everything seems fine until I try to insert a new Property into the database. If the property does not contain any Activity, it works, but all hell breaks loose when I add some new activities to the new Property. As it turns out after 2 days of crawling the web and fiddling around, I noticed that in the EF store (SSDL) some of the constraints between entities were not picked up during the update process. Property_Activity table which links properties and activities show only one constraint FK_Property_Activity_Activity but FK_Property_Activity_Property was missing. I knew this is an Entity Framework anomoly because when I switched the relationship in the database to: Asset <-- Asset_Activity <-- Activity After an update, all foreign key constraints are picked up and the save is successful, with or without activities in the new property. Is this intended or a bug in EF? How do I get around this problem? Should I abandon inheritance altogether?

  • how to keep a nativewindow on top

    - by Freddy Rios
    I need to keep a NativeWindow I am creating on top of the main window of the application. Currently I am using alwaysInFront = true, which is not limited to the windows in the application. I can successfully synchronize the minimize/restore/move/resize actions, so the top window behaves appropriately in those cases. Even though using this option has the drawback that if I alt-tab to other application the window goes on top of the other application. Because of the above I am trying to get it to work without using the alwaysInFront. I have tried using orderInFrontOf and orderToFront, which gets it in place but when I click an area in the main window the top one becomes hidden i.e. air makes it the top one. I have tried capturing activate/deactivate events but it only happens on the first click, so on the second click the top window becomes hidden again. I also tried making the top window active when the main one becomes active, but that causes the main one to loose focus and I can't click on anything. Ps. I am doing this to improve the behavior of a HTMLOverlay I am using - see http://stackoverflow.com/questions/1044927/flex-air-htmlloader-blank-pop-up-window-when-flash-content-is-loaded/1077738#1077738

  • Possible to recover mysql root pass with sudo server access?

    - by jonathonmorgan
    I've inherited development for a website on vps hosting, and have login info for a user with sudo privileges, but don't have the password for the mysql root user. After digging around a little, it looks like the only way to fix this is to stop mysql (something like this: http://waoewaoe.wordpress.com/2010/02/03/recover-reset-mysql-root-password/). But because the website it's serving is currently in production, I'm hoping you guys can enlighten me to any potential consequences (or let me know if there's typically a file where the password would be accessible). a) during the time mysql is stopped, information in the database won't be accessible, right -- even by other users? b) will resetting the root password have any impact on other users after mysql has restarted? Will their username/passwords still be valid? The current application is using an account with limited privileges to read/write to the database, and while 5min downtime in the middle of the night would probably go unnoticed, half a day while I tie up loose ends/figure out what I screwed up will land in me hot water. Thanks in advance for your help!

  • Send form when hitting enter

    I have a form in a jQuery enabled site. The form does not feature an <input type="submit"> button. For that reason, it's not submitted when you hit enter. What's the recommended way to emulate such behaviour? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head><title></title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"><!-- $(function(){ $("form input:first").focus(); }); //--></script> </head> <body> <form action="" method="post"> <input type="text" name="user"> <input type="password" name="pass"> </form> </body> </html>

  • Zend Sessions problem with IE8

    - by Emil
    I'm running a Zend Framework powered website and it seems to have serious problems with sessions. I have a 5 step process where I save the form data in the session between the steps and then save it into the database on the last step. When we built the site sometimes the session just went away and forced us to restart. Now it seems to work again but recently we discovered an issue with Internet Explorer 8. It fails between step 2 - 3 and forgets the session. It works fine in IE6, IE7, FF, Chrome, Safari and even in my mobile web browser (SE P1). We're storing our sessions in the database and if I deactivate the session db handler it works. What's the difference between using the database and not using it for sessions? Do I loose something if I switch back? Bootstrap: /* Start session */ $saveHandler = new Zend_Session_SaveHandler_DbTable(array( 'name' => 'sessions', 'primary' => 'id', 'modifiedColumn' => 'modified', 'dataColumn' => 'data', 'lifetimeColumn' => 'lifetime' )); Zend_Session::rememberMe((int) $config->session->lifetime); $saveHandler->setLifetime((int) $config->session->lifetime) ->setOverrideLifetime(true); Zend_Session::setSaveHandler($saveHandler); Zend_Session::start(); and in my step controller $session = new Zend_Session_Namespace('wizard'); Then I'm just working with $session saving data in a stdClass in $session.

  • What are some choices to port existing Windows GUI app written in C to Linux?

    - by Warner Young
    I've been tasked with porting an existing Windows GUI app to Linux. Ideally, I'd like to do this so the same code base can be used to build either the Windows version or the Linux version. I'll be doing my work on Ubuntu 9.04. After searching around, it's unclear to me what tools are best suited to help me with this. A list of loose requirements would be: The code is in C, not C++, and should compile to build both Windows and Linux versions. Since it's existing code, and fairly large, converting to a managed language like .NET is out of the question for now. I would prefer if I can use the same dialogs in both systems. In Windows, putting up a dialog is pretty simple. You build the dialog in the Resource Editor in Visual Studio, then call DialogBox() API, and handle the event messages. I would really like to find something that can do the equivalent on the Linux side. It would also be nice to have a good IDE similar to Visual Studio. Any helps or hints would be appreciated. Thanks,

  • VS2008 DataSet Wizard doesn't match tables for updating

    - by James H
    Hi all, first question ever on this site. I've been having a real stubborn problem using Visual Studio 2008 and I'm hoping someone has figured this out before. I have 2 libraries and 1 project that use strongly typed datasets (MSSQL backend) that I generated using the "Configure DataSet with Wizard" option on in Data Sources. I've had them working just fine for awhile and I've written a lot of code in the non-designer file for the row classes. I've also specified a lot of custom queries using the dataset designer. This is all work I can't afford to loose. I've recently made some changes to re-organize my libraries which included changing the names of the libraries themselves. I also changed the connection string to point to a different database which is a development copy (same exact schema). Problem is now when I open up "Configure DataSet with Wizard" to pickup a new column I've added to one of the tables it no longer matches the tables correctly in the wizard. The wizard displays all of the tables in the database and none of them have check boxes next to them (ie: are not part of this dataset). Below those it shows all of the tables again but with red Xs and these are checked. Basically meaning that Visual Studio sees all of the tables it currently has in the DataSet and sees all of the tables in the database, but believes they are no longer the same and thus do not match! I've had this same thing happen quite awhile back and I think I just re-built the xsd from scratch and manually copied the code over and then had to redefine all of the custom queries I built in the dataset designer. That's not a good solution. I'm looking for 2 answers: 1. What causes this to happen and how to prevent it. 2. How do I fix this so that the wizard once again believes the tables in its xsd are the same tables that are in the database (yes, they have the exact same names still). Thanks.
