Delphi 2010: how to stamp file version in *.pas and increment it on each save w/o CVS/SVN tools?

- by FractalizeR

Hello. How do I have in each *.pas file it's version, incrementing on each save in some comment line? I have plenty of files on three PCs and I need to have a possibility to quickly check their versions against each other. This problem is easily solved by some centralized version control, but some sources I have cannot be trusted to external servers and are kept on TrueCrypt volumes. May be some addon can do that for me? Something like changing $Version: to $Version: 121212 on each save, incrementing this value? May be there is another way also of solving this problem?

Phonegap/Cordova orientation change Android 4

- by user1477576

I have a problem changing the orientation of the device (Android 4). In other versions it works fine. Versión of Cordova: cordova-1.8.0.js / cordova-1.8.1.js In Android 4 the app crash or show: "A network error occurred. (file:///android_asset/www/index.html)" I searched a lot about this and no answer solves the problem. In most cases users suggest adding: android:configChanges="orientation|keyboardHidden|screenSize" In other cases: super.setIntegerProperty("loadUrlTimeoutValue",60000); That not work for me :( My manifest activity: <activity android:name=".AppNameActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|screenSize"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> The application should run on Android 2.2 to 4. Thank you very much for the help.

CSS3 box-shadow + inset + RGBA

- by mkotechno

I'm doing some tests with new features of CSS3, but this combination only works in lastest versions of Chrome and Firefox, but not in Safari or Opera: box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -webkit-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -moz-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); I really don't know if they fails in the box-shadow itself, in the inset parameter, or in RGBA color. It's a syntax error or simply Safari and Opera lacks on this?

How to keep plug-in manifest version and pom version in sync in Maven with Tycho

- by abhin4v

I am using Maven with Tycho to build an eclipse plugin. Tycho generates the pom.xml file for Maven by inspecting the manifest file of the plugin. Now both the manifest file and the pom file have the version of the plugin and they need to be kept in sync manually. This is because I have done some customization in the generated pom file and cannot overwrite it every time I change the version in the manifest. My question here is, is there a way to keep these versions in sync automatically using Tycho?

How to structure a multilingual website for search engines?

- by Nirmal

I have this website which decides on the display language by a GET parameter. http://www.mysite.com/index.php?page=home&locale=en which is rewritten as http://www.mysite.com/en/home When no language is specified, the system defaults to English (en). Now how do I tell the search engines that many versions of the website exist? When the search bot enters the site, it will trigger the default English Language and after finishing, will just leave the site without considering other languages. I can very well have a sitemap with links to the default pages of each language, so the bot can navigate from there. But how do I say the bot that the entry in the sitemap is the home page for that language? Like if someone searches for 'mi sitio', they should be presented with the result http://www.mysite.com/es/home and not some other internal page. Any light on this? Thanks.

Interview question: Check if one string is a rotation of other string.

- by Webdev

A friend of mine was asked the following question today at interview for the position of software developer. Given two string s1 and s2 how will you check if s1 is a rotated version of s2 ? Example: if s1 = "stackoverflow"; then the following are some of its rotated versions: "tackoverflows" "ackoverflowst" "overflowstack" where as "stackoverflwo" is not a rotated version. The answer he gave was: Take s2 and find the logest prefix that is a substring of s1, that will give you the point of rotation. Once you find that point, break s2 at that point to get s2a and s2b, then just check if concatenate(s2a,s2b) == s1 It looks like a good solution to me and my friend. But the interviewr though otherwise. He asked for a simpler solution. Please help me by telling how would you do this in Java/C/C++ ? Thanks in advance.

How do I branch an individual file in SVN?

- by Michael Carman

The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

Java regex basic usage problem

- by Ernelli

The following code works: String str= "test with foo hoo"; Pattern pattern = Pattern.compile("foo"); Matcher matcher = pattern.matcher(str); if(matcher.find()) { ... } But this example does not: if(Pattern.matches("foo", str)) { ... } And neither this version: if(str.matches("foo")) { ... } In the real code, str is a chunk of text with multiple lines if that is treated differently by the matcher, also in the real code, replace will be used to replace a string of text. Anyway, it is strange that it works in the first version but not the other two versions.

How to implement blocking request-reply using Java concurrency primitives?

- by Uri

My system consists of a "proxy" class that receives "request" packets, marshals them and sends them over the network to a server, which unmarshals them, processes, and returns some "response packet". My "submit" method on the proxy side should block until a reply is received to the request (packets have ids for identification and referencing purposes) or until a timeout is reached. If I was building this in early versions of Java, I would likely implement in my proxy a collection of "pending messages ids", where I would submit a message, and wait() on the corresponding id (with a timeout). When a reply was received, the handling thread would notify() on the corresponding id. Is there a better way to achieve this using an existing library class, perhaps in java.util.concurrency? If I went with the solution described above, what is the correct way to deal with the potential race condition where a reply arrives before wait() is invoked?

In Delphi, Is there a way to adjust the line spacing of a TMemo?

- by Kieran

I'm working with a TMemo component to display some text in a limited space. Currently it's using a truetype font which doesn't ship with windows and is installed by the app when it runs. On my PC (Running Windows XP), the spacing between each line of text seems to be about eight pixels. On a different PC running Windows 7, the line spacing seems to be about 14 pixels, which is pushing the bottom row of text out of visibility on the memo. So, My question is really this: Is this caused by the different versions of Windows? It's all I could think that was different. Is there some way I can adjust this value so it would be consistent across all instances of the application, wherever it was running? Alternatatively, is there a different component I could use which might let me tweak this value?

Wordpress Trackbacks Not Being Applied

- by Dustin Digmann

I am using Wordpress 2.9.1. I recently noticed the trackbacks are not being sent - internal or external. I see two issues I would like to solve. 1) My site has a default, global ping hub which it should notify. This value is not being set into the 'to_ping' value in the *_post table. 2) When I manually enter a trackback in the post, I notice the 'to_ping' value is properly set. It never sends the ping though. The 'pinged' value is always empty. With older versions of WP, this seemed to work automatically.

Why can't I install psycopg2? (Python 2.6.4, PostgreSQL 8.4, OS X 10.6)

The psycopg2 documentation was not helpful.

- by Maxem

Hi, I would like to do something like this in my application layout: %title= "#{yield(:sub_title)} - Page Name" and in a real view - content_for :sub_title do Übersicht # I tried Übersicht, != "Übersicht" and a bunch of other methods what happens is, I either get the black pound with the question mark in it - wrong encoding or the raw string (&UumI;bersicht). Does anyone know a way how to get this to work? Another requirement is that I'd like to show user generated content in the title and this content may or may not have umlauts in it. Used versions: Haml 3.0.11, Rails 3 beta4 and currently for development JRuby 1.5

I need a program to store the database script for oracle

- by Hakan Kara

We are developing a project that has 3 enviroments (development, test, production) So there are 3 databases (actually more than 3, because we have 5 customers so we have more than 10 databases) and they must be synchronised. There are 30 coders working for this project. Everone adds, deletes, and changes procedures, table columns etc. We need a program to store our database scripts like visual studio's team foundation server. See the change history of script file. Everyone must access that program and be able to put their scripts. Recover previous versions of script file. Execute these scripts over a selected database. Compare databases by procedures (not only by name, by content of procedure), functions, table columns, packages etc. I am searching a program like that. Which one do you suggest me?

Out-Of-Memory while doing Core Data migration

- by Kamchatka

Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?

How to register a model in django-tagging anywhere not in the applications?

- by culebrón

Is it possible to register a model in django-tagging not in tagging app, nor in my app? The standard way is to edit apps/myapp/models.py this way: from apps import tagging tagging.register(MyModel) I want to keep both applications without changes, for example, to be able to pull new versions and just replace them. So I tried putting this into project settings.py, in the end, but of course this fails. from apps.myapp.models import MyModel from apps import tagging tagging.register(MyModel) (This fails when importing MyModel.) Any other way?

Record locking problem between linux and Windows

- by PabloG

I need to run a bunch of old DOS FoxPro / Clipper applications in linux under DOSEMU. The programs access their "databases" located on a network server (could be a Windows or Linux server) Actually, the programs ran fine, but I cannot manage to make the record locking work as supposed: I can run a program in two terminals (or the server and any terminal for instance) and lock the same record in both. Now, I'm using Tiny Core Linux as terminal and Windows XP as server, accesing the shared files via CIFS and the latest DOSEMU (1.4.0), but I tried with various combinations of server (Ubuntu 7 to 9, Damn Small Linux, XP) <- protocol (CIFS, samba, various versions of smbclient) <- client (same as server) with no luck I tried to configure the server part to work without oplocks in samba (after reading the entire O'Reilly Samba book locking chapter in http://oreilly.com/catalog/samba/chapter/book/ch05_05.html ) and in XP (\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\UseOpportunisticLocking = 0) but the problem persist. Any ideas? TIA, Pablo

Type patterns and generic classes in Haskell

- by finnsson

I'm trying to understand type patterns and generic classes in Haskell but can't seem to get it. Could someone explain it in laymen's terms? In [1] I've read that "To apply functions generically to all data types, we view data types in a uniform manner: except for basic predefined types such as Float, IO, and ?, every Haskell data type can be viewed as a labeled sum of possibly labeled products." and then Unit, :*: and :+: are mentioned. Are all data types in Haskell automatically versions of the above mentioned and if so how do I figure out how a specific data type is represented in terms of :*:, etc? The users guide for generic classes (ch. 7.16) at haskell.org doesn't mention the predefined types but shouldn't they be handled in every function if the type patterns should be exhaustive?

Operating System for first production windows server code?

- by Unkwntech

I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

Declaring pointers; asterisk on the left or right of the space between the type and name?

- by GenTiradentes

I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

Python -- what is NOT in 2.7 that IS in 3.1? So many things have been back-ported, what is NOT?

- by StuFuller

I've been following the saga of Python 3.x and have watched the 3.x features gradually getting back-ported to the 2.x line. Most of the libraries I use haven't been ported and some (e.g. Twisted) seem covertly or overtly hostile to 3.x to varying degrees. At any rate, there has been very little movement towards compatible versions of many of them. Expecially the larger ones. So, my question is, with all the features that have been backported, what is still available in 3.x that's NOT been back-ported? It's pretty easy to find what has been backported, but not what's left. Right now, porting to 3.x just seems like all pain, and I can't see the gain; maybe an "Only in 3.x" list would let me see the light... Thanks, Stu

Layout Bug in IE (div relative)

- by Florian

Hi, I have a problem with IE (all versions). I have a header div with a relative position and inside this another div with absolute position and right alignment. <div id="header" style="position: relative; width: 1000px; height: 60px;"> content http://stadtwerke-bitburg.de/fileadmin/overflow_prob_IE.png Now when I open the pulldown menu in FF/Safari/Opera everything is all right. Whereas in IE everything which is taller than 60px disappears behind my header div. Is there a workaround for this problem with CSS or do I have to write javascript to get this fixed? thx TC
