  • Make shortened and long urls play together on the same domain (RewriteRule).

    - by Renato Renato
    Long story short, I want to have both example.com/aJ5 and example.com/any-other-url working together. I'm using apache and not very good at writing regex. I have already a global RewriteRule which sends everything to the app entry point. What I need is to tell apache if length($path) is <= 5 chars then rewrite to another location. I know I can use {1,5} like syntax in regex, but don't really know if it's what I'm looking for. I'd like to implement this at web-server level rather than php level. Any help is appreciated.

  • GetProperties() to return all properties for an interface inheritance hierarchy

    - by sduplooy
    Assuming the following hypothetical inheritance hierarchy: public interface IA { int ID { get; set; } } public interface IB : IA { string Name { get; set; } } Using reflection and making the following call: typeof(IB).GetProperties(BindingFlags.Public | BindingFlags.Instance) will only yield the properties of interface IB, which is "Name". If we were to do a similar test on the following code, public abstract class A { public int ID { get; set; } } public class B : A { public string Name { get; set; } } the call typeof(B).GetProperties(BindingFlags.Public | BindingFlags.Instance) will return an array of PropertyInfo objects for "ID" and "Name". Is there an easy way to find all the properties in the inheritance hierarchy for interfaces as in the first example?

  • Weird use of generics

    - by Karl Trumstedt
    After a bit of programming one of my classes used generics in a way I never seen before. I would like some opinions of this, if it's bad coding or not. abstract class Base<T> : where T : Base<T> { // omitted methods and properties. virtual void CopyTo(T instance) { /*code*/ } } class Derived : Base<Derived> { override void CopyTo(Derived instance) { base.CopyTo(instance); // copy remaining stuff here } } is this an OK use of generics or not? I'm mostly thinking about the constraint to "itself". I sometimes feel like generics can "explode" to other classes where I use the Base class.

  • Rails - building an absolute url in a model's virtual attribute without url helper

    - by Nick
    I have a model that has paperclip attachments. The model might be used in multiple rails apps I need to return a full (non-relative) url to the attachment as part of a JSON API being consumed elsewhere. I'd like to abstract the paperclip aspect and have a simple virtual attribute like this: def thumbnail_url self.photo.url(:thumb) end This however only gives me the relative path. Since it's in the model I can't use the URL helper methods, right? What would be a good approach to prepending the application root url since I don't have helper support? I would like to avoid hardcoding something or adding code to the controller method that assembles my JSON. Thank you

  • kvm -net only passing broadcast, multicast, and guest destination traffic

    - by user52874
    Figured this out just last week, but I can't find it now. Even printed it out. Can't find that either. Frustrating...so...help! Configured a 'monitoring' nic on a kvm guest (running 'Security Onion, if it matters). I read (somewhere) that the default nic configuration for a kvm guest is to only pass broadcast traffic, multicast traffic, and traffic with the guest's mac as a destination. There is an option to override this behaviour, and pass all traffic. It's something like --mac-filtering=no, or --mac-restriction=no, or something like that. Worked beautifully. Does this look at all familiar to anyone who can clue me in to the exact option syntax? thx.

  • FTP "PUT" fails from Virtual Machine, but not host PC: 504 Command not implemented for that paramete

    - by BrianH
    I have an FTP Script I'm using to automate a file transfer. The transfer works fine on my PC (XP SP2), but when I try and run it on a VM on my PC (XP SP2), the "put" commands gives off: 504 Command not implemented for that parameter. FTP File: open [ftp site] [username] [password] cd [directory on FTP server] binary hash put ..\[subfolder1]\[Subfolder2]\[subfolder3]\[filename] bye The FTP site/server is around the world, and not under my control. From what I understand of a 504, that means the command should NEVER work, but since the same script DOES work on my PC (hosting the VM), that eliminates syntax, file naming, etc. The put command when triggered from the VM, actually creates a 0 length file on the target FTP server, but doesn't populate the file.

  • PHP: prevent invocation of method X from from context != Y

    - by sunwukung
    This is a tricky one. I am "emulating" ZF Bootstrapping (surface appearance). Don't ask me why, call it academic interest. So I have a Bootstrap Abstract with a method "run" that iterates over itself to locate any methods prefixed with "init". The application looks for a user defined class which extends this class, in which the user can define any number of methods in this way. However, I want to prevent the user from being able to execute the "run" command of it's parent class, while still exposing the same command for the client code. Anyone got any thoughts/advice/guidance? regards SWK

  • Should USB controller drivers be updated?

    - by Coldblackice
    Should USB controller drivers be updated? In Windows 7, many of the core system devices/buses/controllers still use stock Microsoft drivers dating back to 2006 -- things such as USB controllers and the PCI bus (and subsequent devices in the tree). Should these be getting updated? I would think that surely there would have been improvements/fixes/updates to some or any of these drivers by now, now over 7 years old. Does Windows know "best" in this case, updating these respective drivers when it's needed, or should the user be keeping an eye out for drivers in this "vein" of devices (meaning integrated/core/non-pluggable system devices that are built into the motherboard)?

  • [C++]Advantage of using a static member function instead of an equivalent non-static member function

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

  • converting node inheritance to hiera

    - by quickshiftin
    I'm working on moving over a node inheritance tree to hiera. Presently working on the hierarchy. Prior to hiera, my nodes had a hierarchy as such base pre-prod qa nodes staging nodes development nodes prod nodes Now I'm trying to get the same tier with hiera. Starting out I have this :hierarchy: - base - "%{environment}" - "%{clientcert}" but I need another level to capture pre-prod and prod. My thought would be to add an entry to puppet.conf, something like [agent] realm = pre-prod then :hierarchy: - base - "%{realm}" - "%{environment}" - "%{clientcert}" A couple of questions Are you allowed to place arbitrary properties into puppet.conf? Will hiera see the realm property?

  • Windows Event Viewer - XML Custom Filter

    - by Frank
    <QueryList> <Query Id="0" Path="Application"> <Select Path="Application"> *[EventData[Data and (Data="Error")]] </Select> </Query> </QueryList> I believe the above XML custom filter would work if I wanted to check for Events where "Data" equals the word "Error". However, what I want to express is that I want the Events where Data CONTAINS the word "Error" . . . how do I express that? I've Goggled around, but I can find no references to Regular Expression like pattern matching in the Event Viewer. XPath has "contains", but if Event Viewer will support it, I cannot seem to figure out the syntax for invoking it.

  • SVN - Migrate to new server

    - by Jeff Bilbro
    We recently acquired another company that brought with them some crufty old linux servers. One of them is their SVN server - which died last night. I don't know a lot about Subversion, but I have reading up on it this morning - as you can imagine. We do have backups, but their just the whole directory tree for the subversion, not individual dumps. Since the server is now dead, I cannot do any dumps. How do I migrate that Subversion directory to a new server and get it up and running again? I'm not seeing a lot of examples. The new server is a VM running RHEL5. Thanks, Jeff

  • In ADUC MMC, Advanced View, how to get Attribute Editor tab on the result of a Find?

    - by geoffc
    In Win2008 MS added a new Tab on objects in ADUC. Called Attribute Editor it is like Novell Console One's Other tab, or an arbitrary LDAP editor view, or an ADSI Edit style view. Basically it shows all allowed attributes for the object class, and allows you to edit according to your permissions. You need to enable Advanced Options in the View menu before it shows up. This is great, however it only shows up when you browse the directory tree and select an object. If you use the Find tool and open an object Attribute Editor is not shown. How annoying! Especially if your domain has more than 2000 users in a single container, then you almost must use Find to get to an object. Is there any way to make the Attribute Editor tab show up after using Find to open an object?

  • How to configure sudoers with path wildcards?

    - by C. Lee
    I need sudo for a command for any path under a particular area. Example: sudo mycommand /opt/apps/myapp/... What is the sudoers syntax to allow this command to run in any path that falls under /opt/apps/myapp? This is Solaris 10 sudo. Thank you for your reply, but I don't need wildcards for the path to the commands, but wildcards for the arguments for the commands. For example, we want to do something like... sudo mycmd /opt/userarea/area1 sudo mycmd /opt/userarea/area1/area2 sudo mycmd /opt/userarea/area1/area2/area3 So far, using wildcards for the arguments in sudoers look like this: /opt/userarea/* /opt/userarea/*/* And it seems like if we want to have N levels of directories, then we need N lines in sudoers! Is there a better way to include all N levels in one line in sudoers? Thanks.

  • Slideshow screensaver in Win-7 vs. XP

    - by daveh551
    Since I skipped Vista, this may be an old question, I don't know. In XP, the built-in SlideShow (Photos) screensaver would randomly rotate among images not just in the directory specified in the settings, but also in any sub-directories (and on down) of that directory. When I use the Photos screensaver in Win-7, it seems to use only images in the directory I specify, ignoring the rest of the tree below that. Is there a way to get the XP behavior? Alternatively, is there some other public domain/open source Screen Saver with that or similar behavior that I can install?

  • Future of VB.NET? [closed]

    - by Alex Yeung
    Hi all, I worked with C# for years. Last year, I changed my job and the company use VB.NET. Of course, theoretically C# and VB.NET are very similar and I easily adapted. However, I have worked for VB.NET for 1 year. I cannot see any future of VB.NET. As a programming language, it is so foo. Here is a list of what C# can do but VB.NET cannot Case insensitive variables how to think a new variable name? If I have a property called FolderPath, i need to establish another private variable called _folderPath or m_folderPath. In C#, FolderPath and folderPath are two variables. Moreover, it gets compile error if variable name is same as a class name. For example Dim guid = Guid.NewGuid(). (What the...) Again, I need to think a new variable name. Adhoc scope In C#, we could use {...} to create a adhoc scope and all resource in {...} will not affect the code outside. However there is not such syntax in VB.NET. I could only use If True Then and End If to make a local scope which is so unclear. In-Method Region Sometime, it is unavoidable to have a long long method. VB.NET does not support in-method region. I always need to scroll down for 1000 lines. It wastes my time. No multi-line string definition In C#, we could var s = @"..." to define a multi-line string. In VB.NET there is no direct method to do that. The indirect way is use XML-literal string. Dim s = <![CDATA[...]]>.Value. However it is unclear. No block comment In C#, we have line comment // and block comment /* ... */. However in VB.NET we only have line comment which is a very big trouble for me. No statement end symbol Statements are separated by line break in VB.NET; while statements are separated by ; in C#. Underscore I think many people know underscore _ is continue statement symbol. I really disagree with that. I know MS VB.NET language team is going to remove the underscore syntax from VB.NET. However what can we do now? Although underscore is removed in the future, what's the advantage of that? I cannot see any advantage! With scope With scope is an evil scope. Although it allows shorter statement, it is hard to trace. Default Namesapce in project level It is a nightmare for me. The only advantage of VB.NET is property initialization. I think C# cannot do that (correct me if I am wrong.) Public Property ThisIsMyProperty As String = "MyValue" Remarks: I don't think optional method parameters is an advantage of OOP. By those disadvantages, I cannot see the future of VB.NET. Anyone sees the future of VB.NET?

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • In Windows, a batch file with a recursive for loop and a file name including blanks

    - by uvts_cvs
    Hello, I have a folder tree, like this (it's only an example, it will be deeper in my real case): C:\test | +---folder1 | foo bar.txt | foobar.txt | +---folder2 | foo bar.txt | foobar.txt | \---folder3 foo bar.txt foobar.txt My files have one or more spaces in the name and I need to perform a command on them, so I am interested in foo bar.txt but not in foobar.txt. I tried (inside a batch file): for /r test %%f in (foo bar.txt) do if exist %%f echo %%f where the command is the simple echo. It does not work because the space is skipped and I get no output. This works but it is not what I need: for /r test %%f in (foobar.txt) do if exist %%f echo %%f It prints: C:\test\folder1\foobar.txt C:\test\folder2\foobar.txt C:\test\folder3\foobar.txt I tried using the quotation mark (") but it does not work: for /r test %%f in ("foo bar.txt") do if exist %%f echo %%f It does not work because the quotation mark is still included in the output: C:\test\folder1\"foo bar.txt" C:\test\folder2\"foo bar.txt" C:\test\folder3\"foo bar.txt"

  • Indentation-based Folding for TextMate

    - by Craig Walker
    SASS and HAML have indentation-based syntax, much like Python. Blocks of related code have the same number of spaces at the start of a line. Here's some example code: #drawer height: 100% color: #c2c7c4 font: size: 10px .slider overflow: hidden height: 100% .edge background: url('/images/foo') repeat-y .tab margin-top = !drawer_top width: 56px height: 161px display: block I'm using phuibonhoa's SASS bundle, and I'd like to enhance it so that the various sections can fold. For instance, I'd like to fold everything under #drawer, everything under .slider, everything under .edge, etc. The bundle currently includes the following folding code: foldingStartMarker = '/\*|^#|^\*|^\b|^\.'; foldingStopMarker = '\*/|^\s*$'; How can I enhance this to fold similarly-indented blocks?

  • How can I install a custom (patched) PECL extension?

    - by JKS
    I'm trying to use the htscanner PECL extension on my CentOS 5/PHP 5.2.6 machine, but there's a bug in the latest version where a newline character is added to the end of every php_value directive. This behavior causes my include_path and error_log values not to work. The bug and the patch are documented on the PECL site: http://pecl.php.net/bugs/bug.php?id=16891 I've downloaded the latest version, applied the patch, and re-compressed the package — but I can't get the PECL installer to accept it — or any local package, for that matter. I've tried every variation of the pecl install syntax that I can think of, and the only times I'm able to get it to work, it downloads an online copy first and ignores the local copy. Can anyone recommend a method for installing a PECL extension from a local file? Thanks for your consideration.

  • Conditional blocks of code in linux bash

    - by Arek
    Nearly everybody knows very useful && and || operators, for example: rm myf && echo "File is removed successfully" || echo "File is not removed" I've got a question: how to put a block of commands after && or || operators without using the function? For example I want to do: rm myf && \ echo "File is removed successfully" \ echo "another command executed when rm was successful" || \ echo "File is not removed" \ echo "another command executed when rm was NOT successful" What is the proper syntax of that script?

  • Use delegate for Projection in Linq to SQL

    - by Redeemed1
    I have code something like this in an IRepository implementation in Linq to Sql: var newlist = from h in list where h.StringProp1 == "1" select new MyBusinessBO{ firstProp = h.StringProp1, secondProp = h.StringProp2 }; The projection into MyBusinessBO is not difificult but when the Business Object has many properties the projection code becomes very lengthy. Also, as the projection can occur in several places in the Repository we break the DRY principle. Is there any way to abstract out the projection or replace it with a delegate? I.e. replace the code firstProp = h.StringProp1, secondProp = h.StringProp2 with something reusable?

  • What hardware is at physical address 0x80000000 on powerpc New World Macintosh?

    - by tinkerer
    Open Firmware device tree gives no clue what device might decode at physical address 0x80000000 to 0x8008200 on a G4 New World Macintosh. The mmu has three adjacent Virtual=Real translations for that block. They are the only address translations reported between the top or physical dram at 20000000 and the start of the PCI bridges at f0000000. (A possible clue is that frame-buffer-addr is reported as 9c008000 by Open Firmware, and that is not in the reported translation table either). I believe the architecture has been around since about 1999.
