  • Who Knows AppWeb HTTP Server And It's Embedded PHP?

    - by Andi
    Hi all, on my search for a fast but comfortable web server I dropped into the homepage of EmbedThis(TM) AppWeb(TM) HTTP server. This one has 2 licencse models, GPLv2 and a commercial one with support. On the first view it looks good: the footprint is not too big, it is fast and it has a lot of configuration otions. The most important thing would be a fast PHP execution using a built-in PHP library. Unfortunately this PHP library doesn't include every option, especially "gettext" which one I need for I18N. My target platform is Linux on an embedded device with an ARM based CPU. Does anybody have experiences with the issues mentioned above? Kind regards, Andi

  • Machine learning in OCaml or Haskell?

    - by griffin
    I'm hoping to use either Haskell or OCaml on a new project because R is too slow. I need to be able to use support vectory machines, ideally separating out each execution to run in parallel. I want to use a functional language and I have the feeling that these two are the best so far as performance and elegance are concerned (I like Clojure, but it wasn't as fast in a short test). I am leaning towards OCaml because there appears to be more support for integration with other languages so it could be a better fit in the long run (e.g. OCaml-R). Does anyone know of a good tutorial for this kind of analysis, or a code example, in either Haskell or OCaml?

  • User Interface functionality modelling languages?

    - by naugtur
    I am looking for a UI functionality modelling language (UML-alike "thing", but for user interfaces) that is already accepted and maybe has its design patterns and handles the problem better than state or activity diagram. (If there is no such thing I'm planning to develop that BTW :)) This question came to mind as a result of a discovery that UML and its diagrams fails at describing complicated UI functionality with event-driven flow of execution (ie. javascript/jQuery big projects) EDIT: I've been thinking of using BPMN but It was not created for this purpose. EDIT2: See this community topic of mine - I decided to start developing said language.

  • UpdatePanel refreshes only once

    - by superexsl
    Hi, I have two updatepanels inside an accordion control, laid out like this: <accordion> <first pane content> <updatepanel UpdateMode="conditional"> <contenttemplate>...</contenttemplate> <triggers>...</triggers> </updatepanel> </first pane content> <second pane content> <updatepanel> <contenttemplate>...</contenttemplate> <triggers>...</triggers> </updatepanel> </second pane content> </accordion> The panel updates once, but after that, no updates take place. If I refresh the page, then I can see the updated information. This means that the database is being updated, but the updatepanel isn't refreshing (after refreshing the first time). Why is this happening? This has been bugging me for days, so any advice would be much appreciated. Thanks!

  • How to modify/replace option set file when building from command line?

    - by Heinrich Ulbricht
    I build packages from a batch file using commands like: msbuild ..\lib\Package.dproj /target:Build /p:config=%1 The packages' settings are dependent on an option set: <Import Project="..\optionsets\COND_Defined.optset" Condition="'$(Base)'!='' And Exists('..\optionsets\COND_Defined.optset')"/> This option set defines a conditional symbol many of my packages depend on. The file looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <DCC_Define>CONDITION;$(DCC_Define)</DCC_Define> </PropertyGroup> <ProjectExtensions> <Borland.Personality>Delphi.Personality.12</Borland.Personality> <Borland.ProjectType>OptionSet</Borland.ProjectType> <BorlandProject> <Delphi.Personality/> </BorlandProject> <ProjectFileVersion>12</ProjectFileVersion> </ProjectExtensions> </Project> Now I need two builds: one with the condition defined and one without. My attack vector would be the option set file. I have some ideas on what to do: write a program which modifies the option set file, run this before batch build fiddle with the project files and modify the option set path to contain an environment variable, then have different option sets in different locations But before starting to reinvent the wheel I'd like to ask how you would tackle this task? Maybe there are already means meant to support such a case (like certain command line switches, things I could configure in Delphi or batch file magic).

  • Better way to clean this messy bool method

    - by Luís Custódio
    I'm reading Fowler Clean Code book and I think that my code is a little messy, I want some suggestions: I have a simple business requirement that is return the date of new execution of my Thread. I've two class fields: _hour and _day. If actual day is higher than my _day field I must return true, so I'll add a month to "executionDate" If the day is the same, but the actual hour is higher than _hour I should return true too. So I did this simple method: private bool ScheduledDateGreaterThanCurrentDate (DateTime dataAtual) { if (dateActual.Day > _day) { return true; } if (dateActual.Day == _day && dateActual.Hour > _hour) { return true; } if (dateActual.Day == _day && dateActual.Hour == _hour) if (dateActual.Minute>0 || dateActual.Second>0) return true; return false; } I'm programming with TDD, so I know that the return is correct, but this is bad maintain code right?

  • Need help understanding _set_security_error_handler()

    - by Emil D
    So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

  • Trying to execute netdom.exe from a ruby script or IRB does nothing

    - by Joraff
    I'm trying to write a script that will rename a computer and join it to a domain, and was planning to call on netdom.exe to do the dirty work. However, trying to run this utility in the script (same results in irb) does absolutely nothing. No output, no execution. I tried with backticks and with the system() method. System() returns false for everything but system("netdom") (which returns true). Backticks never return anything but an empty string. I have verified that netdom runs and works in the environment the script will be running in, and I'm calling other command-line utilities earlier in the script that work (w32tm, getmac, ping). Here's the exact line that gets executed: `netdom renamecomputer %COMPUTERNAME% /NewName:#{newname} /force` FYI, This is windows 7 x64

  • Setting a breakpoint in a T4 template

    - by Dave Swersky
    I'm trying to debug the execution of a T4 template in Visual Studio 2008. All the information I'm finding on debugging T4 templates in Visual Studio 2008 say that you can set a breakpoint (red dot) in the template as if it were a regular code file. I have the Clarius T4 code highlighter installed, so my T4 template is colored, but I can't set a breakpoint. When I click in the margin nothing happens. I've tried Debugger.Break(), and it launches a new instance of VS.NET, but it can't load the code from my template. I get a dialog that says "There is no source code available for the current location." This happens if I have the same project loaded in the another instance of if I spin up a new instance. What gives?

  • Does Ivy's url resolver support transitive retrieval?

  • Javascript debugging: stopping/breaking at every javascript invocation

    - by portoalet
    I am dealing with a complex legacy javascript code base, and it's difficult to figure out where to put breakpoint (I have to find the files, put a breakpoint in firebug etc). Is there a way so that Firebug breaks on the first javascript execution that it encounters every time? In other words, every time I click on something on the page, and if a javascript code is executed, I want Firebug to break on that line? Of course I don't want Firebug to stop when it executes it's internal javascript. Is this possible?

  • Why should i use EJB?

    - by Nitesh Panchal
    Hello, As we all know that EJB's in 3.1 or 3.0 are simple POJOs. You just need to give annotations here and there and it gets converted to EJB from simple class. So, now my question is why should i use EJBs at all? Can i not do without them? In .Net i created class library and got things done. I never felt the need for anything like EJB. Simple classes were enough. Then, why in Java people stress on EJB? What is difference between a simple POJO and EJB in terms of execution and memory? Further which function should i write in EJB and which should i write in simple class? Should i dump every function in EJB only? or there is some kind of strategy? Does EJB provide anything special?

  • Remove certain keys from a dictionary in python

    - by Margaret
    I'm trying to construct a dictionary that contains a series of sets: {Field1:{Value1, Value2, Value3}, Field2{Value4}} The trouble is, I then wish to delete any fields from the dictionary that only have one value in the set. I have been writing code like this: for field in FieldSet: if len(FieldSet[field]) == 1: del(FieldSet[field]) But receive the error "RuntimeError: dictionary changed size during execution". (Not surprising, since that's what I'm doing.) It's not the be-all and end-all if I have to knock together some sort of workaround, but is it possible to do this?

  • How can I find out if two arguments are instances of the same, but unknown class?

    - by Ingmar
    Let us say we have a method which accepts two arguments o1 and o2 of type Object and returns a boolean value. I want this method to return true only when the arguments are instances of the same class, e.g.: foo(new Integer(4),new Integer(5)); Should return true, however: foo(new SomeClass(), new SubtypeSomeClass()); should return false and also: foo(new Integer(3),"zoo"); should return false. I believe one way is to compare the fully qualified class names: public boolean foo(Object o1, Object o2){ Class<? extends Object> c1 = o1.getClass(); Class<? extends Object> c2 = o2.getClass(); if(c1.getName().equals(c2.getName()){ return true;} return false; } An alternative conditional statement would be : if (c1.isAssignableFrom(c2) && c2.isAssignableFrom(c1)){ return true; } The latter alternative is rather slow. Are there other alternatives to this problem?

  • R:how to get grep to return the match, rather than the whole string

    - by Mike Dewar
    Hi, I have what is probably a really dumb grep in R question. Apologies, because this seems like it should be so easy - I'm obviously just missing something. I have a vector of strings, let's call it alice. Some of alice is printed out below: T.8EFF.SP.OT1.D5.VSVOVA#4 T.8EFF.SP.OT1.D6.LISOVA#1 T.8EFF.SP.OT1.D6.LISOVA#2 T.8EFF.SP.OT1.D6.LISOVA#3 T.8EFF.SP.OT1.D6.VSVOVA#4 T.8EFF.SP.OT1.D8.VSVOVA#3 T.8EFF.SP.OT1.D8.VSVOVA#4 T.8MEM.SP#1 T.8MEM.SP#3 T.8MEM.SP.OT1.D106.VSVOVA#2 T.8MEM.SP.OT1.D45.LISOVA#1 T.8MEM.SP.OT1.D45.LISOVA#3 I'd like grep to give me the number after the D that appears in some of these strings, conditional on the string containing "LIS" and an empty string or something otherwise. I was hoping that grep would return me the value of a capturing group rather than the whole string. Here's my R-flavoured regexp: pattern <- (?<=\\.D)([0-9]+)(?=.LIS) nothing too complicated. But in order to get what I'm after, rather than just using grep(pattern, alice, value = TRUE, perl = TRUE) I'm doing the following, which seems bad: reg.out <- regexpr( "(?<=\\.D)[0-9]+(?=.LIS)", alice, perl=TRUE ) substr(alice,reg.out,reg.out + attr(reg.out,"match.length")-1) Looking at it now it doesn't seem too ugly, but the amount of messing about it's taken to get this utterly trivial thing working has been embarrassing. Anyone any pointers about how to go about this properly? Bonus marks for pointing me to a webpage that explains the difference between whatever I access with $,@ and attr.

  • CRM plugin to execute when opportunity is reopened

    - by splatto
    I need to write a plugin for Dynamics CRM 4.0 that executes when a closed opportunity is reopened in order to change the salesstagecode. My questions are: When I register a new step to the plugin, what attribute(s) should I filter on? What property on the entity should I check the value of? and What should I look for the value of this entity to be so I can determine if the plugin execution should continue? I've typically written asynchronous workflows and my experience writing plugins is still developing, so I'd appreciate any help and clarification that can be offered. Please see below the plugin skeleton I've written public void Execute(IPluginExecutionContext context) { if (context.InputParameters.Properties.Contains("Target") && context.InputParameters.Properties["Target"] is DynamicEntity) { ICrmService service = context.CreateCrmService(false); DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties["Target"]; if (entity.Name == EntityName.opportunity.ToString()) { if (entity.Properties.Contains(/*What Property Should I Check Here?*/)) { //And what value should I be looking for in that property? } } } }

I have used only SAP BO Data Integrator ETL tool and it cannot query flat files from another Server: during execution, all files must be located on the Job Server machine that executes the job.
