• socket problem with MySQL

  - by Hristo

  This is a recent problem... MySQL was working and a couple of days ago I must have done something. I deleted MySQL and tried reinstalling using the .dmg file. The mysql.sock file never gets created and I get the following error messages: Hristo$ mysql Enter password: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) I also tried stopping Apache and installing but Apache gave me an error... I don't know if this is good or bad: Hristo$ sudo apachectl stop launchctl: Error unloading: org.apache.httpd I tried the MacPorts installation as well but the socket file still didn't get created. I don't really know what to do and I don't want to reinstall Snow Leopard and start from scratch :/ I also tried installing the 32-bit version and same deal. No luck. Finally... I tried doing the source installation but when I get to the configuration step, I get the following error: -bash: ./configure: No such file or directory The file is "mysql-5.1.47-osx10.6-x86_64.tar.gz" so I think it is the proper file for source installation and yes I have a 64 bit system. I don't know what to do anymore. Any ideas? Thanks, Hristo

• People not respecting good practices at workplace

  - by VexXtreme

  Hi There are some major issues in my company regarding practices, procedures and methodologies. First of all, we're a small firm and there are only 3-4 developers, one of which is our boss who isn't really a programmer, he just chimes in now and then and tries to do code some simple things. The biggest problems are: Major cowboy coding and lack of methodologies. I've tried explaining to everyone the benefits of TDD and unit testing, but I only got weird looks as if I'm talking nonsense. Even the boss gave me the reaction along the lines of "why do we need that? it's just unnecessary overhead and a waste of time". Nobody uses design patterns. I have to tell people not to write business logic in code behind, I have to remind them not to hardcode concrete implementations and dependencies into classes and cetera. I often feel like a nazi because of this and people think I'm enforcing unnecessary policies and use of design patterns. The biggest problem of all is that people don't even respect common sense security policies. I've noticed that college students who work on tech support use our continuous integration and source control server as a dump to store their music, videos, series they download from torrents and so on. You can imagine the horror when I realized that most of the partition reserved for source control backups was used by entire seasons of TV series and movies. Our development server isn't even connected to an UPS and surge protection. It's just plugged straight into the wall outlet. I asked the boss to buy surge protection, but he said it's unnecessary. All in all, I like working here because the atmosphere is very relaxed, money is good and we're all like a family (so don't advise me to quit), but I simply don't know how to explain to people that they need to stick to some standards and good practices in IT industry and that they can't behave so irresponsibly. Thanks for the advice

• Do MSDTC and disaster recovery go together?

  - by DevDelivery

  Our application writes to multiple Sql Server databases within a distributed transaction. The Ops guys are saying that this messes up their disaster recovery plan because while the transactions on the live tables may commit at the same time, the log shipping on the separate databases happen at slightly different times. So in in a disaster recovery situation, there will be a few partial transactions. Is there a method for maintaining separate but synced databases in DR? Or do we have to re-design to relatively independent databases (or a single database)?

• MongoDb vs Ehcache caching advise for speeding up read only mysql Database

  - by paddydub

  I'm building a Route Planner Webapp using Spring/Hibernate/Tomcat and a mysql database, I have a database containing read only data, such as Bus Stop Coordinates, Bus times which is never updated. I'm trying to make the app run faster, each time the application is run it will preform approx 1000 reads to the database to calculate a route. I have setup a Ehcache which greatly improves the read from database times. I'm now setting terracotta + Ehcache distributed caching to share the cache with multiple Tomcat JVMs. This seems a bit complicated. I've tried memcached but it was not performing as fast as ehcache. I'm wondering if a MongoDb would be better suited. I have no experience with nosql but I would appreciate if anyone has any ideas. All i need is quick access to the read only database.

• appstats broken filename in callstack

  - by Ray Yun

  When I visit appstats page and expand callstack, the file path has <path[N]> prefix. So click the file link then emit no such file or directory error. Stack: /google/appengine/datastore/datastore_rpc.py:951 make_rpc_call() /google/appengine/datastore/datastore_query.py:993 _make_query_result_rpc_call() /google/appengine/datastore/datastore_query.py:714 run_async() /google/appengine/datastore/datastore_query.py:685 run() /google/appengine/api/datastore.py:1281 GetBatcher() /google/appengine/api/datastore.py:1351 Get() /google/appengine/ext/db/init.py:1831 fetch() /google/appengine/ext/db/init.py:1778 get() /apps/fbapp/fbutil.py:232 oauth_load_fb_user() /apps/fbapp/fbutil.py:84 require_account() the error message for appengine source: [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/ipaddr/google/appengine/datastore/datastore_rpc.py' the error message for my source: IOError [Errno 2] No such file or directory: u'/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/lib/antlr3/apps/fbapp/fbutil.py' I guess this was path problem and found some official comment from google. If your request handlers modify sys.path, you must make the same modifications to sys.path in appengine_config.py so the Appstats web interface can see all files. Actually I'm using appengine_django and two path was inserted to sys.path. I did it same again at appengine_django.py but also failed. Maybe some custom setting with appengine_config.py can solve this problem but doesn't figure out how to fix it. What can I do?

• How do I guarantee cleanup code runs in Windows C++ (SIGINT, bad alloc, and closed window)

  - by Meekohi

  I have a Windows C++ console program, and if I don't call ReleaseDriver() at the end of my program, some pieces of hardware enter a bad state and can't be used again without rebooting. I'd like to make sure ReleaseDriver() gets runs even if the program exits abnormally, for example if I hit Ctrl+C or close the console window. I can use signal() to create a signal handler for SIGINT. This works fine, although as the program ends it pops up an annoying error "An unhandled Win32 exception occurred...". I don't know how to handle the case of the console window being closed, and (more importantly) I don't know how to handle exceptions caused by bad memory accesses etc. Thanks for any help!

• Bulk Copy from one server to another

  - by Joseph

  Hi All, I've one situation where I need to copy part of the data from one server to another. The table schema are exactly same. I need to move partial data from the source, which may or may not be available in the destination table. The solution I'm thinking is, use bcp to export data to a text(or .dat) file and then take that file to the destination as both are not accessible at the same time (Different network), then import the data to the destination. There are some conditions I need to satisfy. 1. I need to export only a list of data from the table, not whole. My client is going to give me IDs which needs to be moved from source to destination. I've around 3000 records in the master table, and same in the child tables too. What I expect is, only 300 records to be moved. 2. If the record exists in the destination, the client is going to instruct as whether to ignore or overwrite case to case. 90% of the time, we need to ignore the records without overwriting, but log the records in a log file. Please help me with the best approach. I thought of using BCP with query option to filter the data, but while importing, how do I bypass inserting the existing records? If I need to overwrite, how to do it? Thanks a lot in advance. ~Joseph

• displaying images in a list box so the image resizes based on parent container

  - by MikeU

  I have an expander with a list box in it that displays image thumbnails. I want the images to be sized according to the size of the listbox and the list box to be sized based on the width of the expander. When I expand the expander I want the list box and the images to resize also. Does anyone know how I can accomplish this? <Expander Style="{DynamicResource ExpanderStyle}" Name="pictureExpander" IsExpanded="True" ExpandDirection="Left" Collapsed="pictureExpander_Collapsed" Expanded="pictureExpander_Expanded" Grid.Column="4"> <ListBox Name="photoList" ItemsSource="{Binding Source={StaticResource PhotoBin}}" IsSynchronizedWithCurrentItem="True" HorizontalAlignment="Stretch" ScrollViewer.CanContentScroll="False"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Style.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Yellow" /> </Style.Resources> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="BorderBrush" Value="Black"/> <Setter Property="BorderThickness" Value="5"/> </Trigger> </Style.Triggers> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Image Source="{Binding FileLocation}" Margin="0,5" HorizontalAlignment="Stretch" MouseLeftButtonDown="DragImage" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Expander>

• how do you use ${word_selection} in an Eclipse PDT template?

  - by pocketfullofcheese

  I was recently trying to use some code templates with Eclipse PDT 2.1 to speed up some common tasks. We use a lot of getters/setters, so I wrote the following template. function get${word_selection}() { return $$this->getData('${word_selection}'); } function set${word_selection}($$${word_selection}) { $$this->setData('${word_selection}', $$${word_selection}); } I named the template "getset" and the only way I know to use the Code Assist is to type: "getset" then hit my code assist keys (I have it set to Esc, but I think the default was Ctrl+Space). The problem is, this doesn't actually let me select a word to be used by the ${word_selection}. My question is: how do I type in my template name, hit the key combo, and have a word selected all at the same time?

• Python-daemon doesn't kill its kids

  - by Brian M. Hunt

  When using python-daemon, I'm creating subprocesses likeso: import multiprocessing class Worker(multiprocessing.Process): def __init__(self, queue): self.queue = queue # we wait for things from this in Worker.run() ... q = multiprocessing.Queue() with daemon.DaemonContext(): for i in xrange(3): Worker(q) while True: # let the Workers do their thing q.put(_something_we_wait_for()) When I kill the parent daemonic process (i.e. not a Worker) with a Ctrl-C or SIGTERM, etc., the children don't die. How does one kill the kids? My first thought is to use atexit to kill all the workers, likeso: with daemon.DaemonContext(): workers = list() for i in xrange(3): workers.append(Worker(q)) @atexit.register def kill_the_children(): for w in workers: w.terminate() while True: # let the Workers do their thing q.put(_something_we_wait_for()) However, the children of daemons are tricky things to handle, and I'd be obliged for thoughts and input on how this ought to be done. Thank you.

• Which web containers install themselves well as a Windows service?

  - by Thorbjørn Ravn Andersen

  We have had a web application product for several years, and used Tomcat to deploy it under Windows as it registers itself as a Windows service so it starts and stops automatically. We may now happen to need more JEE facilitites than is provided by Tomcat (we are very tempted by the JEE 6 things in the container) so the question is which Open Source JEE containers works well as Windows services. Since Glassfish is the only JEE 6 implementation right now, it would be nice if it works well, but I'd like to hear experiences and not just what I can read from brochures. If not, what else do people use? EDIT: This goes for web containers too, and not just JEE containers. We will probably keep the necessary stack included until we find the right container and it gets JEE6 support. EDIT: I want this to work as distributed. I'm not interested in manually hacking wrappers etc., but want the installation process to handle the creation and removal of the service.

• Error Cannot create an Instance of "ObjectName" in Designer when using <UserControl.Resources>

  - by Mike Bynum

  Hi All, I'm tryihg to bind a combobox item source to a static resource. I'm oversimplfying my example so that it's easy to understand what i'm doing. So I have created a class public class A : ObservableCollection<string> { public A() { IKBDomainContext Context = new IKBDomainContext(); Context.Load(Context.GetIBOptionsQuery("2C6C1Q"), p => { foreach (var item in SkinContext.IKBOptions) { this.Add(item); } }, null); } } So the class has a constructor that populates itself using a domaincontext that gets data from a persisted database. I'm only doing reads on this list so dont have to worry about persisting back. in xaml i add a reference to the namespace of this class then I add it as a usercontrol.resources to the page control. <UserControl.Resources> <This:A x:Key="A"/> </UserControl.Resources> and then i use it this staticresource to bind it to my combobox items source.in reality i have to use a datatemplate to display this object properly but i wont add that here. <Combobox ItemsSource="{StaticResource A}"/> Now when I'm in the designer I get the error: Cannot Create an Instance of "A". If i compile and run the code, it runs just fine. This seems to only affect the editing of the xaml page. What am I doing wrong?

• My SqlComand on SSIS - DataFlow OLE DB Command seems not works

  - by Angel Escobedo

  Hello Im using OLE DB Source for get rows from a dBase IV file and it works, then I split the data and perform a group by with aggregate component. So I obtain a row with two columns with "null" value : CompanyID | CompanyName | SubTotal | Tax | TotalRevenue Null Null 145487 27642.53 173129.53 this success because all rows have been grouped with out taking care about the firsts columns and just Summing the valuable columns, so I need to change that null for default values as CompanyID = "100000000" and CompanyName = "Others". I try use SqlCommand on a OLE DB Command Component : SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC <property id="1505" name="SqlCommand" dataType="System.String" state="default" isArray="false" description="The SQL command to be executed." typeConverter="" UITypeEditor="Microsoft.DataTransformationServices.Controls.ModalMultilineStringEditor, Microsoft.DataTransformationServices.Controls, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" containsID="false" expressionType="Notify">SELECT "10000000" AS RUCCLI , "Otros - Varios" AS RAZCLI FROM RGVCAFAC</property> but nothings happens, why? and finally the task finish when the data is inserted on a SQL Server Table.

• Indy IdSMTP and attachments in Thunderbird

  - by Lobuno

  Hello! Using the latest snapshot of Indy tiburon on D2010. A very simple project like: var stream: TFileStream; (s is TidSMTP and m is TidMessage) begin s.Connect; Stream := TFileStream.Create('c:\Test.zip', fmOpenRead or fmShareExclusive); try with TIdAttachmentMemory.Create(m.MessageParts, Stream) do begin ContentType := 'application/x-zip-compressed'; Name := ExtractFilePath('C:\'); //' FileName := 'Test.zip'; end; finally FreeAndNil(Stream); end; s.Send(m); s.Disconnect(); end; Everything works Ok in Outlook, The bat!, OE, yahoo, etc... but in Thunderbird the attachment is not shown. Looking at the source of the message in Thunderbird, the attachment is there. The only difference I can find between messages send by indy and other clients is that Indy messages have this order: Content-Type: multipart/mixed; boundary="Z\=_7oeC98yIhktvxiwiDTVyhv9R9gwkwT1" MIME-Version: 1.0 while any other clients have the order: MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="Z\=_7oeC98yIhktvxiwiDTVyhv9R9gwkwT1" Don't know if THAT is the source of the problem, but if so: is this a bug on Thunderbird or is this a problem with indy which "malforms" the headers of the messages? Is this order a problem? Does that matter anyway?

• WPF resource merged to Application.Resources but not resolved at runtime

  - by arconaut

  I have a brush that is part of a ResourceDictionary that is merged to Application.Resources. But for some reason it's not resolved at runtime when a style is being applied to one of the controls. However, if I call Application.Current.FindResource("BrushName") from the Immediate Window at the time when exception is thrown, the resource is found. Am I missing something? Isn't WPF supposed to try to look for the resource in the app's resources? UPDATE The application is quite big, so I can't post all actual code but here's the way the resources are merged and used: Brushes.xaml <ResourceDictionary ...> <SolidColorBrush x:Key="BrushName" Color="#12345678" /> <\ResourceDictionary> SomeStyles.xaml <ResourceDictionary ...> <Style x:Key="SomeStyle"> <Setter Property="SomeProperty" Value="{StaticResource BrushName}" /> </Style> </ResourceDictionary> App.xaml <Application ...> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Brushes.xaml" /> <ResourceDictionary Source="SomeStyles.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application ...> And then some control might use the style using the resource like this: ... Style={StaticResource SomeStyle} ...

• WCF Service Layer in n-layered application: performance considerations

  - by Marconline

  Hi all. When I went to University, teachers used to say that in good structured application you have presentation layer, business layer and data layer. This is what I heard for more than 5 years. When I started working I discovered that this is true but sometimes is better to have more than just three layers. Two or three days ago I discovered this article by John Papa that explain how to use Entity Framework in layered application. According to that article you should have: UI Layer and Presentation Layer (Model View Pattern) Service Layer (WCF) Business Layer Data Access Layer Service Layer is, to me, one of the best ideas I've ever heard since I work. Your UI is then completely "diconnected" from Business and Data Layer. Now when I went deeper by looking into provided source code, I began to have some questions. Can you help me in answering them? Question #0: is this a good enterpise application template in your opinion? Question #1: where should I host the service layer? Should it be a Windows Service or what else? Question #2: in the source code provided the service layer expose just an endpoint with WSHttpBinding. This is the most interoperable binding but (I think) the worst in terms of performances (due to serialization and deserializations of objects). Do you agree? Question #3: if you agree with me at Question 2, which kind of binding would you use? Looking forward to hear from you. Have a nice weekend! Marco

• ADODB Connection String: Workgroup Information file is Missing?

  - by Mohgeroth

  I have a few data sources in access that I need to connect to programatically to do things with behind the scenes and keep visibility away from users. Said datasource has a password 'pass' as I'm going to call it here. Using this connection method I get an error attempting to use the open method Dim conn as ADODB.Connection Set ROBBERS.conn = New ADODB.Connection conn.open "Provider=Microsoft.Jet.OLEDB.4.0;" _ & "Data Source=\\pep-home\projects\billing\autobilling\DPBilling2.mdb;" _ & "Jet OLEDB:Database Password=pass;", "admin", "pass" "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." Due to planning to move into 2007, we are not using nor have ever used a workgroup identification file through access. The database password on the data source was set through the Set Databa Password which had to be done on an exclusive open. Ive spent a good while changing around my connection options, where to put the passwords etc and either cannot find the right format, or (why I'm asking here) I think there may be some other unknown that I must setup to do this. Anyone out there got some useful information?

• Currency exchange rates for paypal

  - by Jacco

  Does anyone know a way to get the currency exchange rates for paypal? We have custom shopping cart and use Paypal (Website Payments Standard) to handle payments. Our 'home' currency is Euro, but we would like to present our customers the option to pay in different currencies (USD, CAD, AUD and GBP). PayPal offers the option to:     a) automatically convert our Euro quoted prices to, for example, USD upon checkout     b) checkout in USD directly With option a): We get paid in Euro, the customer pays for the currency exchange (good). The customer does not know what he/she is going to be charged in USD until checkout. (bad) With option b) The customer pays in USD, then the currency is converted into EUR and we pay the the currency exchange. The customer never has to worry about the different currencies (excellent) We do not know the exchange rate PayPal is going to use so we cannot quote the correct prices to our customer (showstopper) So my question is:   Does anybody know a way to get the PayPal exchange rates? or   Does anybody know how to make a good estimate? Update: PayPal updates it's exchange rate 2 times a day. (at least, that is what they state). They use the Interbank Exchange Rate provided by ??? and add a 2.5% spread above this rate to determine their retail foreign exchange rates. Unforunately, there the Interbank Exchange Rates vary from source to source and from minute to minute. We have been monitoring the PayPal exchange rates and cross referenced them with the Official reference rates provides by the European Central Bank. the results vary widely, somewhere from 1 to 6 ! percent...

• WPF Update Binding when Bound directly to DataContext w/ Converter

  - by Adam

  Normally when you want a databound control to 'update,' you use the "PropertyChanged" event to signal to the interface that the data has changed behind the scenes. For instance, you could have a textblock that is bound to the datacontext with a property "DisplayText" <TextBlock Text="{Binding Path=DisplayText}"/> From here, if the DataContext raises the PropertyChanged event with PropertyName "DisplayText," then this textblock's text should update (assuming you didn't change the Mode of the binding). However, I have a more complicated binding that uses many properties off of the datacontext to determine the final look and feel of the control. To accomplish this, I bind directly to the datacontext and use a converter. In this case I am working with an image source. <Image Source="{Binding Converter={StaticResource ImageConverter}}"/> As you can see, I use a {Binding} with no path to bind directly to the datacontext, and I use an ImageConverter to select the image I'm looking for. But now I have no way (that I know of) to tell that binding to update. I tried raising the propertychanged event with "." as the propertyname, which did not work. Is this possible? Do I have to wrap up the converting logic into a property that the binding can attach to, or is there a way to tell the binding to refresh (without explicitly refreshing the binding)? Any help would be greatly appreciated. Thanks! -Adam

• 'Hot code replace' not working -- Eclipse doesn't change any code on JBoss

  - by Bernhard V

  Hello, fellow visitors! I'm currently experiencing a problem with 'hot code replace' not working on Eclipse Galileo and JBoss 4.2.3. Among other applications I'm running an exploded Java WAR on my local JBoss. The project from which it is build is managed by Maven. I build the project using the Maven goal war:exploded and then I copy that directory to JBoss with an ANT script. When I'm now running the application and set a breakpoint anywhere in the code, Eclipse properly halts at that line in the debug mode. But when I'm making a change to the source file and save it, Eclipse doesn't apply this change to the JBoss. For example, when I make a normal code line into a comment, the debugger still steps over this comment as if it was regular Java code. Or when I remove a line, the debugger seems to get out of sync with the file and starts stepping over parenthesis. But I'm not getting any 'hot code replace error'-messages either. It seems to me that Eclipse applies the changes to the source files, but doesn't apply it to the JBoss. Are there any special preferences that have to be turned on in order to make hot code replace work? Or are there any mistakes in how I build and deploy the application to the JBoss? I'd appreciate your help very much. Thank you. Bernhard V

• dynamically create class in scala, should I use interpreter?

  - by Phil

  Hi, I want to create a class at run-time in Scala. For now, just consider a simple case where I want to make the equivalent of a java bean with some attributes, I only know these attributes at run time. How can I create the scala class? I am willing to create from scala source file if there is a way to compile it and load it at run time, I may want to as I sometimes have some complex function I want to add to the class. How can I do it? I worry that the scala interpreter which I read about is sandboxing the interpreted code that it loads so that it won't be available to the general application hosting the interpreter? If this is the case, then I wouldn't be able to use the dynamically loaded scala class. Anyway, the question is, how can I dynamically create a scala class at run time and use it in my application, best case is to load it from a scala source file at run time, something like interpreterSource("file.scala") and its loaded into my current runtime, second best case is some creation by calling methods ie. createClass(...) to create it at runtime. Thanks, Phil

• Linked servers SQLNCLI problem. "No transaction is active"

  - by Felipe Fiali

  Im trying to execute a stored procedure and simply insert its results in a temporary table, and I'm getting the following message: The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "MyServerName" was unable to begin a distributed transaction. OLE DB provider "SQLNCLI" for linked server "MyServerName" returned message "No transaction is active.". My query looks like this: INSERT INTO #TABLE EXEC MyServerName.MyDatabase.dbo.MyStoredProcedure Param1, Param2, Param3 Exact column number, names, the problem is not the result. MSDTC is allowed and started in both computers, Remote procedure calling too. The machines are not in the same domain, but I can execute remote queries from my machine and get the result. I can even execute the stored procedure and see its results, I just can't insert it in another table. Help, please? :)
