• FreeBSD jail with IPFW with loopback - unable to connect loopback interface

  I am trying to configure a one IP jail with loopback interface, but I am unsure how to configure the IPFW rules to allow traffic to pass between the jail and the network card on the server.

  - by Waheed Sayed

  While using the .Net client TIBCO EMS, How to monitor outgoing messages from my .Net Tibco client? I'm going to send Application-level, not jms-level, acknowlegements and replies. How can I tell If the application sent them or not? If the client failed to send a message will it throw an exception or store the message to try again later? Bottom line, Is there any tool enables me to monitor activities(outgoing) from client point of view?

• primitives of a programming language

  - by Tim

  Hi, Which do the concepts control flow, data type, statement, expression and operation belong to? Syntax or semantics? What is the relation between control flow, data type, statement, expression, operation, function, ...? How a program is built from these primitives level by level? I would like to understand these primitive concepts and their relations in order to figure out what aspects of a new language should one learn. Thanks and regards!

• Grouping records from while loop | PHP

  - by Wayne

  I'm trying to group down records by their priority levels, e.g. --- Priority: High --- Records... --- Priority: Medium --- Records... --- Priority: Low --- Records... Something like that, how do I do that in PHP? The while loop orders records by the priority column which has int value (high = 3, medium = 2, low = 1). e.g. WHERE priority = '1' The label: "Priority: [priority level]" has to be set above the grouped records regarding their level

• Changing IIS URL Rewrite config location

  - by adam

  Hi When used at site level, the IIS7 URL Rewrite 2 module saves its configuration in the web.config file of that site. I'm using Sitecore CMS, and best practice is to store any web.config customisations in a separate config file for ease of upgrading, staging/production setups etc. Is there any way to specify a different config file for IIS7 redirects? I know that application-level rewrites are stored in ApplicationHost.config, but I have several sites running on the server and would like to keep them separated. Thanks, Adam

• editing automated SharePoint emails

  - by Richard Collins

  Sharepoint sends out an automated email when a site collection has reached its quota warning level. The email says: You are receiving this e-mail message because you are an administrator of the following SharePoint Web site, which has exceeded the warning level for storage: https://mysite.xxx.ac.uk/personal/xxx/. To see how much storage is being taken up by this site, go to the View site collection usage summary: https://mysite.xxx.ac.uk/personal/xxx/_layouts/Usage.aspx. The problem is that the usage summary link needs to point somewhere else instead. How can I edit the body of the email to change the link? Thanks.

• How do I fix a "cannot open display" error when opening an X program after ssh'ing with X11 forwarding enabled?

  - by Daryl Spitzer

  After launching the X11 app (XQuartz 2.3.6, xorg-server 1.4.2-apple56) on my Mac (OS X 10.6.8), opening an terminal in X11 and running xhost +, I then ssh -Y to my Ubuntu 10.04 VM (running on VMware Fusion). When I run gedit .bashrc (for example), I get: (gedit:9510): Gtk-WARNING **: cannot open display: set | grep DISPLAY returns nothing. But if I ssh -Y into my Ubuntu 11.04 machine, gedit .bashrc works. echo $DISPLAY returns "localhost:10.0". I tried export DISPLAY=localhost:10.0 while sshed into my VM and then running gedit .bashrc, but I get: (gedit:9625): Gtk-WARNING **: cannot open display: localhost:10.0 What could be different in the configuration of the two difference Ubuntu machines that would explain why one works and the other doesn't? Update: As suggested by Zoredache in the comment below, I ran sudo apt-get install xbase-clients, but I continue to have the same problem.

  What is a positions of SQLCE 3.5 when running on Windows Mobile 6.0 in relation to FIPS compliance. I have read lots of differing reports on this and need a definitive answer, one which comes from a reliable source (please provide links) I have read this "The encryption modes in SQL Server Compact 3.5 are FIPS complaint if FIPS mode is enabled at the OS level." Is this true? if so how does one enable it at the OS level.

• What permissions / ownership to set on PHP Sessions Folder when running FastCGI / PHP-FPM (as user "nobody")?

  - by Professor Frink

  I'm having trouble getting a number of scripts running because PHP-FPM can't write to my session folder: "2009/10/01 23:54:07 [error] 17830#0: *24 FastCGI sent in stderr: "PHP Warning: Unknown: open(/var/lib/php/session/sess_cskfq4godj4ka2a637i5lq41o5, O_RDWR) failed: Permission denied (13) in Unknown on line 0 PHP Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/var/lib/php/session) in Unknown on line 0" while reading upstream" Obviously this is a permission issue; my session folder's owner/group is the webserver's user, NGINX. PHP-FPM runs as nobody though, and hence adding it to the nginx group is not so trivial. A temporary solution is to set the permissions of /var/lib/php/session to 777 - I have a feeling that's not the "best practice" though. What is the best practice when you need to assign a daemon write access to a folder, but it is running as nobody ?

• cpp/Qt : per class debugging

  - by dzen

  I'm developing a Qt application. For each class, I'm trying to mimic the framework, such as error() and errorString() method, use of Private implementation. But I would like to add a per class debugging: Set a macro to the desired level of debug, have a macro or a function that knows the level of debug, and use qDebug() or qWarning() which is class independant, and will know the current class's name (for some pretty prints) Anyone have a good idea to implement this ?

• Method interception in PHP 5.*

  - by Rolf

  Hi everybody, I'm implementing a Log system for PHP, and I'm a bit stuck. All the configuration is defined in an XML file, that declares every method to be logged. XML is well parsed and converted into a multidimensionnal array (classname = array of methods). So far, so good. Let's take a simple example: #A.php class A { public function foo($bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #B.php class B { public function far($boo) { echo $boo; } } Now, let's say I've this configuration file: <interceptor> <methods class="__CLASS_DIR__A.php"> <method name="foo"> <log-level>INFO</log-level> <log-message>Transaction init</log-message> </method> </methods> <methods class="__CLASS_DIR__B.php"> <method name="far"> <log-level>DEBUG</log-level> <log-message>Useless</log-message> </method> </methods> </interceptor> The thing I'd like AT RUNTIME ONLY (once the XML parser has done his job) is: #Logger.php (its definitely NOT a final version) -- generated by the XML parser class Logger { public function __call($name,$args) { $log_level = args[0]; $args = array_slice($args,1); switch($method_name) { case 'foo': case 'far': //case ..... //write in log files break; } //THEN, RELAY THE CALL TO THE INITIAL METHOD } } #"dynamic" A.php class A extends Logger { public function foo($log_level, $bar) { echo ' // Hello there !'; } public function bar($foo) { echo " $ù$ùmezf$z !"; } } #"dynamic" B.php class B extends Logger { public function far($log_level, $boo) { echo $boo; } } The big challenge here is to transform A and B into their "dynamic" versions, once the XML parser has completed its job. The ideal would be to achieve that without modifying the code of A and B at all (I mean, in the files) - or at least find a way to come back to their original versions once the program is finished. To be clear, I wanna find the most proper way to intercept method calls in PHP. What are your ideas about it ??? Thanks in advance, Rolf

• gcc : Is using -Werror and -pedantic considered good practice?

  - by Helper Method

  I'm just digging into the gcc manual and some things are still unclear to me: When specifying a std, should I always use -pedantic in conjunction? When using -g, it the standard level sufficient or should I specify level 3, i.e. -g3? Is it good practice to use -Werror to promote all warnings to errors and -pedantic-errors to promote all pedantic warnings to errors?

• Known Hosts ECDSA Host Key Multiple Domains on One IP

  - by Jonah

  Hello, world!, I have a VPS set up with multiple domain names pointing to it. Arbitrarily, I like to access it via SSH through the domain name I'm dealing with. So for example, if I'm doing something with example1.com, I'll log in with ssh [email protected], and if I'm working with example2.com, I'll log in with ssh [email protected]. They both point to the same user on the same machine. However, because SSH keeps track of the server's fingerprint, it tells me that there is an offending host key, and makes me confirm access. $ ssh [email protected] Warning: the ECDSA host key for 'example2.com' differs from the key for the IP address '123.123.123.123' Offending key for IP in /home/me/.ssh/known_hosts:33 Matching host key in /home/me/.ssh/known_hosts:38 Are you sure you want to continue connecting (yes/no)? Is there a way to ignore this warning? Thanks!

• Outlook 2010 - Export of an Exchange OST to PST creates files with different sizes each time

  - by Jiri Pik

  This is a most weird issue. I have a couple of exchange OST mailboxes, and just for security, I am exporting them using File / Import / Export to a file / Export to PST file. If I run the export consecutively, it always creates files with different file sizes, WITH NO ERROR OR WARNING that something went wrong. The files should be of the same size as you run it right after the previous backup finished. I found out that if the filesize is substantially lower, then a reboot and back up can fix this up. What's your insight into this problem? What could cause that the files have different sizes and what could have caused that there is no warning? I suspected some Windows Search issue as sometimes the backup fails with a dialog error stating that Windows Search terminated the export.

• What is a good platform for building a game framework targetting both web and native languages?

  - by fuzzyTew

  I would like to develop (or find, if one is already in development) a framework with support for accelerated graphics and sound built on a system flexible enough to compile to the following: native ppc/x86/x86_64/arm binaries or a language which compiles to them javascript actionscript bytecode or a language which compiles to it (actionscript 3, haxe) optionally java I imagine, for example, creating an API where I can open windows and make OpenGL-like calls and the framework maps this in a relatively efficient manner to either WebGL with a canvas object, 3d graphics in Flash, OpenGL ES 2 with EGL, or desktop OpenGL in an X11, Windows, or Cocoa window. I have so far looked into these avenues: Building the game library in haXe Pros: Targets exist for php, javascript, actionscript bytecode, c++ High level, object oriented language Cons: No support for finally{} blocks or destructors, making resource cleanup difficult C++ target does not allow room for producing highly optimized libraries -- the foreign function interface requires all primitive types be boxed in a wrapper object, as if writing bindings for a scripting language; these feel unideal for real-time graphics and audio, especially exporting low-level functions. Doesn't seem quite yet mature Using the C preprocessor to create a translator, writing programs entirely with macros Pros: CPP is widespread and simple to use Cons: This is an arduous task and probably the wrong tool for the job CPP implementations differ widely in support for features (e.g. xcode cpp has no variadic macros despite claiming C99 compliance) There is little-to-no room for optimization in this route Using llvm's support for multiple backends to target c/c++ to web languages Pros: Can code in c/c++ LLVM is a very mature highly optimizing compiler performing e.g. global inlining Targets exist for actionscript (alchemy) and javascript (emscripten) Cons: Actionscript target is closed source, unmaintained, and buggy. Javascript targets do not use features of HTML5 for appropriate optimization (e.g. linear memory with typed arrays) and are immature An LLVM target must convert from low-level bytecode, so high-level constructs are lost and bloated unreadable code is created from translating individual instructions, which may be more difficult for an unprepared JIT to optimize. "jump" instructions cause problems for languages with no "goto" statements. Using libclang to write a translator from C/C++ to web languages Pros: A beautiful parsing library providing easy access to the code structure Can code in C/C++ Has sponsored developer effort from Apple Cons: Incomplete; current feature set targets IDEs. Basic operators are unexposed and must be manually parsed from the returned AST element to be identified. Translating code prior to compilation may forgo optimizations assumed in c/c++ such as inlining. Creating new code generators for clang to translate into web languages Pros: Can code in C/C++ as libclang Cons: There is no API; code structure is unstable A much larger job than using libclang; the innards of clang are complex Building the game library in Common Lisp Pros: Flexible, ancient, well-developed language Extensive introspection should ease writing translators Translators exist for at least javascript Cons: Unfamiliar language No standardized library functions, widely varying implementations Which of these avenues should I pursue? Do you know of any others, or any systems that might be useful? Does a general project like this exist somewhere already? Thank you for any input.

Then, I can apt-get install with no problem, but it prompts with following warning: WARNING: The following packages cannot be authenticated! xxxx, xxxx, ... Install these packages without verification [y/N]? Well, you can always install it. But, I can't install from the ubuntu software GUI. Which require trusted source. So, 1. How to force the GUI to install untrusted package? 2. Should I configure GPG to receive some public keys? (I've already installed ubuntu-keyring, debian-keyring, but it still untrusted) 3. Should I configure GPG to receive unknown keys from some specific keyservers, automatically?

  I have an ASP.NET website where i have implemented page level caching using the OutPutCache directive.This boosted the page performance.My pages has few parts(Some buttons,links and labels) which are specific to the logged in user.If user is not logged in,they will see different links.Now Since i implemented the page level caching,Even after the user logged in,It's showing the old page content(Links and buttons meant for the Non logged in User).
