• VCL/Delphi/BCB - which IDE/language should I use?

  - by mawg

  I bought Delphi 1 when it came out - and was hooked. When BCB came out (around D3, iirc), I switched, mainly because I have used C/C++ professionally for a few decades. I have "been away" for 7 or 8 years and am now returning. I still have BCB 6 & Delphi 7 (not to mention Kylix). I always felt more comfortable with C++ than Pascal - purely because of work-day familiarity. But, realistically, iirc, most 3rd party VCL components are coded in Delphi/Pascal. And I think I used to have problems debugging Delphi components from BCB, but I could well remember wrongly. Anyhoo, now I am back and intend to use VCL components / hack the code of same / debug them & code a few of my own. Given that I am slightly more comfortable with C++, is there any compelling reason to choose Delphi over BCB, or is this just a case of how long my particular piece of string is?

• Robust fault tolerant MySQL replication

  - by Joshua

  Is there any way to get a fault tolerant MySQL replication? I am in an environment that has many networking issues. It appears that replication gets an error and just stops. I need it to continue to work and recover from these faults. There is some wrapper software that checks the state of replication and restarts it in the case of losing its log position. Is there an alternative? Note: Replication is done from an embedded computer with MySQL 4.1 to a external computer that has MySQL 5.0.45

• How to capture shift-tab in vim

  - by Yogesh Arora

  I want to use shift-tab for auto completion and shifting code blocks visually. I have been referring to Make_Shift-Tab_work . That link talks about mapping ^[[Z to shift-tab . But i don't get ^[[Z when i press shift-tab. i just get a normal tab in that case. It then talks about using xmodmap -pke | grep 'Tab' to map tab keys. According to that the output should be keycode 23 = Tab or keycode 23 = Tab ISO_Left_Tab However i get keycode 22 = Tab KP_Tab if i use xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' and after that xmodmap -pke | grep 'Tab', I still get keycode 22 = Tab KP_Tab This means running xmodmap -e 'keycode 22 = Tab ISO_Left_Tab' has no effect. In the end the link mentions using xev to see what X recieves when i press shift-tab. But i dont have xev on my system. Is there any other way i can capture shift-tab in vim

• How do I set up mod rewrite to do this?

  - by Ali

  Hi guys heres the scene - I'm building a web application which basically creates accounts for all users. Currently its setup like this the file structure: root/index.php root/someotherfile.php root/images/image-sub-folder/image.jpg root/js/somejs.js When users create an account they choose a fixed group name and then users can join that group. Initially I thought of having an extra textbox in the login screen to enter the group the user belongs to login to. BUt I would like instead to have something like virtual folders in this case: root/group-name/index.php I heard it can be done with apache mod rewrite but I'm not sure how to do this - any help here? Basically instead of having something like &group-name=yourGroupName appended to every page I would just like something of the nature above.

• JQuery: NOT using document.ready and inserting HTML Tags = is this allowed?

  - by jens

  Hello, is this a valid JQuery usage pattern to : <script type="text/javascript"> $("body").prepend('<input type="hidden" id="error" value="show">'); </script> That is using Jquery to manipulate / insert HTML Tags when the Document has NOT YET been loaded (by not using document.ready for the inserting into the DOM)? (Normally I only use document.ready, but in this case I need to insert some Information into the DOM that then is present, when document.ready is called. This is some kind of "happens-before" relations ship I want to achieve so that I am shure when document.ready is called the inserted Form field is available in the document, as I depend on that information. Thank you very much jens

• Detect the URI encoding automatically in Tomcat

  - by Roland Illig

  I have an instance of Apache Tomcat 6.x running, and I want it to interpret the character set of incoming URLs a little more intelligent than the default behavior. In particular, I want to achieve the following mapping: So%DFe => Soße So%C3%9Fe => Soße So%DF%C3%9F => (error) The bevavior I want could be described as "try to decode the byte stream as UTF-8, and if it doesn't work assume ISO-8859-1". Simply using the URIEncoding configuration doesn't work in that case. So how can I configure Tomcat to encode the request the way I want? I might have to write a Filter that takes the request (especially the query string) and re-encodes it into the parameters. Would that be the natural way?

• CherryPy configuration tools.staticdir.root problem

  - by Alan Harris-Reid

  Hi there, How can I make my static-file root directories relative to my application root folder (instead of a hard-coded path)? In accordance with CP instructions (http://www.cherrypy.org/wiki/StaticContent) I have tried the following in my configuration file: tree.cpapp = cherrypy.Application(cpapp.Root()) tools.staticdir.root = cpapp.current_dir but when I run cherrpy.quickstart(rootclass, script_name='/', config=config_file) I get the following error builtins.ValueError: ("Config error in section: 'global', option: 'tree.cpapp', value: 'cherrypy.Application(cpapp.Root())'. Config values must be valid Python.", 'TypeError', ("unrepr could not resolve the name 'cpapp'",)) I know I can do configuration from within the main.py file just before quickstart is called (eg. using os.path.abspath(os.path.dirname(file))), but I prefer using the idea of a separate configuration file if possible. Any help would be appreciated (in case it is relevant, I am using CP 3.2 with Python 3.1) TIA Alan

• NServiceBus pipeline with Distributors

  - by David

  I'm building a processing pipeline with NServiceBus but I'm having trouble with the configuration of the distributors in order to make each step in the process scalable. Here's some info: The pipeline will have a master process that says "OK, time to start" for a WorkItem, which will then start a process like a flowchart. Each step in the flowchart may be computationally expensive, so I want the ability to scale out each step. This tells me that each step needs a Distributor. I want to be able to hook additional activities onto events later. This tells me I need to Publish() messages when it is done, not Send() them. A process may need to branch based on a condition. This tells me that a process must be able to publish more than one type of message. A process may need to join forks. I imagine I should use Sagas for this. Hopefully these assumptions are good otherwise I'm in more trouble than I thought. For the sake of simplicity, let's forget about forking or joining and consider a simple pipeline, with Step A followed by Step B, and ending with Step C. Each step gets its own distributor and can have many nodes processing messages. NodeA workers contain a IHandleMessages processor, and publish EventA NodeB workers contain a IHandleMessages processor, and publish Event B NodeC workers contain a IHandleMessages processor, and then the pipeline is complete. Here are the relevant parts of the config files, where # denotes the number of the worker, (i.e. there are input queues NodeA.1 and NodeA.2): NodeA: <MsmqTransportConfig InputQueue="NodeA.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeA.Distrib.Control" DistributorDataAddress="NodeA.Distrib.Data" > <MessageEndpointMappings> </MessageEndpointMappings> </UnicastBusConfig> NodeB: <MsmqTransportConfig InputQueue="NodeB.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeB.Distrib.Control" DistributorDataAddress="NodeB.Distrib.Data" > <MessageEndpointMappings> <add Messages="Messages.EventA, Messages" Endpoint="NodeA.Distrib.Data" /> </MessageEndpointMappings> </UnicastBusConfig> NodeC: <MsmqTransportConfig InputQueue="NodeC.#" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="NodeC.Distrib.Control" DistributorDataAddress="NodeC.Distrib.Data" > <MessageEndpointMappings> <add Messages="Messages.EventB, Messages" Endpoint="NodeB.Distrib.Data" /> </MessageEndpointMappings> </UnicastBusConfig> And here are the relevant parts of the distributor configs: Distributor A: <add key="DataInputQueue" value="NodeA.Distrib.Data"/> <add key="ControlInputQueue" value="NodeA.Distrib.Control"/> <add key="StorageQueue" value="NodeA.Distrib.Storage"/> Distributor B: <add key="DataInputQueue" value="NodeB.Distrib.Data"/> <add key="ControlInputQueue" value="NodeB.Distrib.Control"/> <add key="StorageQueue" value="NodeB.Distrib.Storage"/> Distributor C: <add key="DataInputQueue" value="NodeC.Distrib.Data"/> <add key="ControlInputQueue" value="NodeC.Distrib.Control"/> <add key="StorageQueue" value="NodeC.Distrib.Storage"/> I'm testing using 2 instances of each node, and the problem seems to come up in the middle at Node B. There are basically 2 things that might happen: Both instances of Node B report that it is subscribing to EventA, and also that NodeC.Distrib.Data@MYCOMPUTER is subscribing to the EventB that Node B publishes. In this case, everything works great. Both instances of Node B report that it is subscribing to EventA, however, one worker says NodeC.Distrib.Data@MYCOMPUTER is subscribing TWICE, while the other worker does not mention it. In the second case, which seem to be controlled only by the way the distributor routes the subscription messages, if the "overachiever" node processes an EventA, all is well. If the "underachiever" processes EventA, then the publish of EventB has no subscribers and the workflow dies. So, my questions: Is this kind of setup possible? Is the configuration correct? It's hard to find any examples of configuration with distributors beyond a simple one-level publisher/2-worker setup. Would it make more sense to have one central broker process that does all the non-computationally-intensive traffic cop operations, and only sends messages to processes behind distributors when the task is long-running and must be load balanced? Then the load-balanced nodes could simply reply back to the central broker, which seems easier. On the other hand, that seems at odds with the decentralization that is NServiceBus's strength. And if this is the answer, and the long running process's done event is a reply, how do you keep the Publish that enables later extensibility on published events?

• Storing date and time as epoch vs native datetime format in the database

  - by zakovyrya

  For most of my tasks I find it much easier to work with date and time in the epoch format: it's trivial to calculate timespan or determine if some event happened before or after another, I don't have to deal with time-zone issues if the data comes from different geographical sources, in case of scripting languages what I usually get from database when I request a datetime-typed column is a string that I need to parse in order to work with it. This list can go on, but for me in order to keep my code portable that's enough to ditch database's native datetime format and store date and time as integer. What do you guys think?

• Flex TextArea leading invalid

  - by Andreas

  Hi, When I set leading to 0 with Verdana (and others to) for a Flex TextArea I get strange results: fontsize - space between baselines 8 - 10 (125%) 10 - 12 (120%) 12 - 14 (117%) 14 - 17 (121%) 16 - 18 (113%) 18 - 22 (122%) 20 - 25 (125%) 25 - 31 (124%) shouldn't all of these be the same (should only be 100%)? Or least follow a pattern, because I can't se any. :( When i set leading to 0, the space between my baselines should be the same as the font size/height. This is not the case here. How do I know how to get the space between the baseline to be equal to the height of the font?

• Get control instance in asp.net dynamic data

  - by Ashwani K

  Hello All: I am creating a web application using Asp.net dynamic data. I am using GridView to show data from the database. In the grid view I am having following code for columns <Columns> <asp:DynamicField DataField="UserId" UIHint="Label" /> <asp:DynamicField DataField="Address" UIHint="Address"/> <asp:DynamicField DataField="CreatedDate" UIHint="Label" /> </Columns> But, before displaying I want to do some processing in C# code for each row. In normal ASP.net grid view we can handle OnRowDataBound method, and using FindControl("controlid") we can get the control instance, but in case of dynamic data, I am not getting any id attribute for columns, so I am not able to get the control instance to show updated data in that control depending on some conditions. Thanks, Ashwani

• Optimizing a large iteration of PHP objects (EAV-based)

  - by Aron Rotteveel

  I am currently working on a project that utilizes the EAV model. This turns out to work quite well, but like many others I am now stumbling upon some performance issues. The data set in this particular case consists of aproximately 2500 entities, each with aprox. 150 attributes. Each entity and each attribute is represented by a PHP-object. Since most parts of the application only iterate through a filtered set of entities, we have not had very large issues yet. Now, however, I am working on an algorithm that requires iteration over the entire dataset, which causes a major impact on performance. This information is perhaps not very much to work with, but since this is an architectural problem, I am hoping for a architectural pattern to help me on the way as well. Each entity, including it's attributes takes up aprox. 500KB of memory.

• Cython Speed Boost vs. Usability

  - by zubin71

  I just came across Cython, while I was looking out for ways to optimize Python code. I read various posts on stackoverflow, the python wiki and read the article "General Rules for Optimization". Cython is something which grasps my interest the most; instead of writing C-code for yourself, you can choose to have other datatypes in your python code itself. Here is a silly test i tried, #!/usr/bin/python # test.pyx def test(value): for i in xrange(value): i**2 if(i==1000000): print i test(10000001) $ time python test.pyx real 0m16.774s user 0m16.745s sys 0m0.024s $ time cython test.pyx real 0m0.513s user 0m0.196s sys 0m0.052s Now, honestly, i`m dumbfounded. The code which I have used here is pure python code, and all I have changed is the interpreter. In this case, if cython is this good, then why do people still use the traditional Python interpretor? Are there any reliability issues for Cython?

• Why this structure should have 48 bytes

  - by Maksee

  I tried to translate some new part of winuser.h header to Delphi. Why this structure is expected to be 48 bytes (only this size was accepted by the corresponding function). With 4-bytes boundary, it looks like it should have 40 bytes. typedef struct tagGESTUREINFO { UINT cbSize; DWORD dwFlags; DWORD dwID; HWND hwndTarget; POINTS ptsLocation; DWORD dwInstanceID; DWORD dwSequenceID; ULONGLONG ullArguments; UINT cbExtraArgs; } GESTUREINFO, *PGESTUREINFO; If it's related to 8-bytes boundary? if so is it relevant to any case where ULONGLONG appears structures?

• Generate canonical / real URL based on base.href or location

  - by blueyed

  Is there a method/function to get the canonical / transformed URL, respecting any base.href setting of the page? I can get the base URL via (in jQuery) using $("base").attr("href") and I could use string methods to parse the URL meant to being made relative to this, but $("base").attr("href") has no host, path etc attributes (like window.location has) manually putting this together is rather tedious E.g., given a base.href of "http://example.com/foo/" and a relative URL "/bar.js", the result should be: "http://example.com/bar.js" If base.href is not present, the URL should be made relative to window.location. This should handle non-existing base.href (using location as base in this case). Is there a standard method available for this already? (I'm looking for this, since jQuery.getScript fails when using a relative URL like "/foo.js" and BASE tag is being used (FF3.6 makes an OPTIONS request, and nginx cannot handle this). When using the full URL (base.href.host + "/foo.js", it works).)

• retrieving background image from div when dynamically set

  - by tixrus

  I am having an issue with setting the background-image of a #x to the background image of #y. Correct me if I am wrong but I think you would do this in a simple case by saying $('#x').css('background-image',$('#y').css('background-image')); The problem is that when y was initially set up, it was set up like this: <div id='y' style='background-image: url(./randomcolor.php?ibase=<?php echo $entity->name; ?>) .... So when it does it, it is getting the URL of the generator, and javascript is just regarding that as a string. Do I have to do an ajax get here, or is there some kind of eval I could use.

• Remote Control software for Mac

  - by MarqueIV

  One of the things I like about Microsoft's RDC Client is that the resolution of the experience is set by the client and not, say, a physical monitor connected to the host, as is the case with VNC; the latter being the protocol used by Mac. This means that even though I'm connecting to a notebook with a 1280x800 physical resolution, via RDC I can run it at 2560x1600 on my 30" monitor. However, that only seems to work for RDC. Does anyone know of something I can run on the Mac that will allow me to remotely control it at a different resolution than what is physically set? TIA, Mark

• MSNP-Sharp Example fails to login, gives SocketException

  - by Nick Udell

  I've just downloaded the MSNP-Sharp library with the aim of creating my own messaging client, however I am struggling to get the example to sign in. The code all compiles and runs, but when I provide my login details and select "Login" I almost immediately get the following SocketException: "No connection could be made because the target machine actively refused it 64.4.9.254:1863" I've stepped through the code and it's the messenger.Connect() function that is causing this, somewhat obviously. When I run the example I only change the login and password details. I am running Windows 7 x86 with the latest version of Windows Live Messenger. I have tried disabling my antivirus, even going as far as to temporarily uninstall it in case that was the error. I have also tried disabling Windows Firewall, with no luck.

• Is an object in objective-c EVER created without going through alloc?

  - by Jared P

  Hi, I know that there are functions in the objective-c runtime that allow you to create objects directly, such as class_createInstance. What I would like to know is if anything actually uses these functions other than the root classes' (NSObject) alloc method. I think things like KVC bindings might, but those aren't present on the iPhone OS (to my knowledge, correct me if I'm wrong), so is there anything that would do this? In case you're wondering/it matters, I'm looking to allocate the size of an instance in a way that circumvents the objc runtime by declaring no ivars on a class, but overriding the +alloc method and calling class_createInstance(self, numberofbytesofmyivars). Thanks

• Sort an array by a child array's value

  - by Evan

  I have an array composed of arrays. I want to sort the parent array by a property of the child arrays. Here's an example array(2) { [0]=> array(3) { [0]=> string(6) "105945" [1]=> string(10) "First name" [2]=> float(0.080878465391) } [1]=> array(3) { [0]=> string(6) "109145" [1]=> string(11) "Second name" [2]=> float(0.0504154818384) } I would like to sort the parent array by [2] ascending in the child arrays, so in this case the result would be the child arrays reversed (.05, 08). Is this possible using any of the numerous PHP sort functions?

• ASP.net MVC - OneToOne relationship with pluralized nomenclature

  - by ludicco

  Hi, I have an OneToOne relationship between my models Account and Company the table names are Accounts and Companies respectively. Here is a brief screenshot of the structure: http://cl.ly/1AEU Everything works well, but mysteriously when I use the OneToOne associations I have accessors like: var db = new DB(); var account = db.Accounts.First(); var company = account.Companies; // note the plural not the singular accessor So, what's happing is that even if using OneToOne association, I still get the plural accessor with "companies" and not "company", if it this is a pure object representation and not an EntitySet generated in case when it s an oneToMany relationship. Is there a way to get this nomenclature to be applied properly? Thanks a lot

• How Can I Check an Object to See its Type and Return A Casted Object

  - by Russ Bradberry

  I have method to which I pass an object. In this method I check it's type and depending on the type I do something with it and return a Long. I have tried every which way I can think of to do this and I always get several compiler errors telling me it expects a certain object but gets another. Can someone please explain to me what I am doing wrong and guide me in the right direction? What I have tried thus far is below: override def getInteger(obj:Object) = { if (obj.isInstanceOf[Object]) null else if (obj.isInstanceOf[Number]) (obj:Number).longValue() else if (obj.isInstanceOf[Boolean]) if (obj:Boolean) 1 else 0 else if (obj.isInstanceOf[String]) if ((obj:String).length == 0 | (obj:String) == "null") null else try { Long.parse(obj:String) } catch { case e: Exception => throw new ValueConverterException("value \"" + obj.toString() + "\" of type " + obj.getClass().getName() + " is not convertible to Long") } }
