  • Should the PHP community start using more discriptive Exceptions?

    - by fireeyedboy
    I work with Zend Framework a lot and I just took a peek at Kohana, and it strikes me as odd that this is a typical scenario in these frameworks: throw Some_Componenents_Exception( 'invalid argument' ); Where I believe this wouldn't be mouch more useful: throw Some_Components_InvalidArgumentException( 'whatever discription' ); Because it is easier to catch. I suspect, but immediately admit it's prejudiced, that the former practice is common in the PHP community. Should we, the PHP community, start using these descriptive types of expections more?

  • data protector red tapes

    - by Caesar
    I am using HP Data Protector A.06.11 in my organization, with HP EML E-SeriesEML library, with 4 drives using LTO-4 tapes, and i am having some problems. Yesterday I put 5 new tapes in the robot and formatted them. At that time, the robot got just those empty 5 tapes with empty space. (all the rest of the tapes are red, or with protection) Today in the morning after the night (1 backup run at night), and 2 of the new tapes are red (the properties are): Writes : 2 Overwrites : 1 Errors : 9 I format one of them, and check for each drive if the tape become red, no one of the drives do it. In the main pool properties, in media condition got: Valid for : 36 (months) Maximum overwrites : 250

  • Audio/video streaming on Windows platform

    - by bushtucker
    I'm building an interactive language learning application to be used in a classroom environment. The idea is that a teacher should be able to talk to the students (=audio stream to all students), let students talk to each other (= audio P2P) in groups of two or more, let students watch a video coming from a the DVD player or coming from a media server. It should be possible to save the audio/video streams. The teacher should also be able to monitor, take-over or block the desktop of the students. The platform is Windows and it's a desktop application, no web application. The audio delay should be as minimal as poosible. Optionally a student sitting at home should be supported, but it's not a high priority. I am now finished with the classroom control part of the application (login, monitor, block, ...) and want to start the audio and video part. I've been evaluating several options like DirectX, GStreamer and SIP but now I have to make a decision. DirectX seems an obvious choice for the Windows platform, but it only lets me capture and playback audio and video. The encoding/decoding/network part I should do myself. GStreamer contains all kinds of options to capture/encode/stream/save audio and video streams. I've experimented a bit with it (ossbuild) and it does seem to involve a lot of trial and error to make something work: - microphone capture (via directsoundsrc) produces cracking noises on some computers - rtpL16 payloader didn't work well - streaming raw audio over the network only working at a sampling rate of 8000, no higher - there are a lot of errors when receiving mpeg4 video (bad I-frame), on some computers worse than others It is my impression that gstreamer is primary targetted at linux platforms. Development and support for the Windows platform seems to be a little behind. Nevertheless it's a powerful framework that could save me months and years of work. SIP seems to be able to do everything I want, but it is targeted towards telephony and IM. I don't know how flexible SIP is. It seems to me that the SIP layer would just be overhead as I already have a central (teacher) application that can control and setup all the streams. The interesting parts of frameworks like opalvoip and freeswitch are the actual audio/video capture, the encoding and transmission. Does anyone know how these interesting parts relate a framework like gstreamer? Are they easy to integrate into a custom application? Are they flexible enough? Does anyone have experience with all or one of these technologies? Maybe there are even other options I can look at? Many thanks for your advice

  • Is it possible to have non-English regional settings with English day/month names?

    - by Indrek
    I live in Estonia where most regional settings (number, currency and date formats) differ from those used in English-speaking countries. For instance, decimal symbol is comma, thousands separator is space, date format is day-month-year, etc. However, if I set my regional settings to Estonian, then day and month names are also shown in Estonian everywhere: This is slightly annoying since the language used for the rest of Windows is English and I'd like the day and month names to be consistent with it. Is this possible while still keeping the local regional settings? One workaround I've tried is to set regional settings to, say, English (UK) and then customise them to match Estonian settings, but that messes up alphabetic sorting - accented letters like "ö" and "ä" are no longer distinguished from their non-accented versions, and "z" is sorted as last rather than at its correct position in the Estonian alphabet (between "s" and "t"). OS is Windows 7 Professional, in case that matters. Edit: alternatively, if there's no built-in way to accomplish what I want, is it possible to create a custom set of regional settings (like one can create custom keyboard layouts)?

  • How to print out information about Task Scheduler in powershell script?

    - by Jimboy
    I am trying to print out information from the Task Scheduler from the local computer in a powershell script so other users can print out this information as well and not have to access the Task Scheduler. I need the script to print out the name, status, triggers, next run time, last run time, last run result, author and created. I can print out the information about the name, next run time, and last run time, but the rest wont print out when i run the script. I have already got a little start on my script and got the fields down. $schedule = new-object -com("Schedule.Service") $schedule.connect() $tasks = $schedule.getfolder("\").gettasks(0) $tasks | select Name,Status,Triggers,NextRunTime,LastRunTime,LastRunResult,Author,Created | ft foreach ($t in $tasks) { foreach ($a in $t.Actions) { $a.Path } } Any help or suggestions would be appreciated.

  • Apache htaccess with mod_expires Not Working for certain directories

    - by keyboarddrummer
    I have a Joomla site that I am trying to enable caching using mod_expires. I have the .htaccess in the root of the site and have added the options as found on the page http://www.pactsoftware.nl/tools/joomla-optimization.html Using the PageSpeed extension in Chrome, prior to adding this in my .htaccess, my site scores a 55 (Caching is at the top, and lists a lot of images, CSS, and JS files). After these directives, it scores 70, with caching in the yellow, but still lists some image files (some are two directories deep and the rest are four). I checked for any other .htaccess files in the Joomla root, but none are between those folders and the root. It is almost as if htaccess only works in that one directory, not the subfolders. I have tried putting a .htaccess in each affected subdirectory, but it does not work. Does anyone have any ideas?

  • Rewrite query string "?x=y" style to "/x/y" style

    - by Ross
    I have a PHP MVC framework I've built from scratch which uses the traditional domain.com/controller/action URL routing. While I'm currently handling the below conversion in the router I'd like to replace them in the URL for cosmetic reasons. For example: controller/action?filter=bank Becomes: controller/action/filter/bank I've done a bit of experimentation with a regex but can't seem to find a match. I'm also not sure how to rewrite it using RewriteCond. Thanks in advance.

  • Are there Python ORMs out there that support multiple independent databases concurrently in use?

    - by sdt
    I'm writing an application in Python where I wish to use sqlite as the backing store for documents edited by the app, with documents generally living in memory, but being saved to disk-based databases when the application saves. Ideally I'd like to use something like an ORM to make access to the data from my Python application code simple. Unfortunately it seems like the majority of Python ORMs, including SQLAlchemy, SQLObject, Django, and Storm, associate the database connection (or engine or whatever) with the classes representing table data, rather than instances of those classes. This restricts these ORMs to working with a single database connection across all instances. Since I'd like to support having multiple documents open simultaneously, this isn't going to work for me. Are there any ORMs out there that support this usage model in Python? Bazaar seems to support this, but it's quite out of date, and at first glance appears to have some other shortcomings. Thanks for any suggestions!

  • How to represent this nested array in YML format?

    - by morpheous
    I want to represent the following nested array structure in YML: container 1: N [contained_item]s where [contained_item] has the following structure contained_item: name: type: category: id: value: I hope the structure I am trying to describe is clear - I have used a mixture of Pseudo UML and YML. An aside: YML is a superset of JSON, and is used in the Symfony framework.

  • jQuery .get appends an unknown variable to URL

    - by ILMV
    I'm using this code as the starting point to an overhaul of our JavaScript framework: $("#get").click(function(){ $("#result").html(ajax_load); $.get( "http://www.google.com", {}, function(responseText){ $("#result").html(responseText); }, "html" ); }); But when the request is made it includes a variable within the URL that I am unfarmiliar with, here is what Firebug says it's requesting: http://www.google.com/?_=1268993359215 How do I get rid of this, when we target our internal scripts it's firing a 404 error :-( Cheers!

  • What is there so useful in the Decorator Pattern? My example doesn't work

    - by Green
    The book says: The decorator pattern can be used to extend (decorate) the functionality of a certain object I have a rabbit animal. And I want my rabbit to have, for example, reptile skin. Just want to decorate a common rabbit with reptile skin. I have the code. First I have abstract class Animal with everythig that is common to any animal: abstract class Animal { abstract public function setSleep($hours); abstract public function setEat($food); abstract public function getSkinType(); /* and more methods which for sure will be implemented in any concrete animal */ } I create class for my rabbit: class Rabbit extends Animal { private $rest; private $stomach; private $skinType = "hair"; public function setSleep($hours) { $this->rest = $hours; } public function setFood($food) { $this->stomach = $food; } public function getSkinType() { return $this->$skinType; } } Up to now everything is OK. Then I create abstract AnimalDecorator class which extends Animal: abstract class AnimalDecorator extends Animal { protected $animal; public function __construct(Animal $animal) { $this->animal = $animal; } } And here the problem comes. Pay attention that AnimalDecorator also gets all the abstract methods from the Animal class (in this example just two but in real can have many more). Then I create concrete ReptileSkinDecorator class which extends AnimalDecorator. It also has those the same two abstract methods from Animal: class ReptileSkinDecorator extends AnimalDecorator { public function getSkinColor() { $skin = $this->animal->getSkinType(); $skin = "reptile"; return $skin; } } And finaly I want to decorate my rabbit with reptile skin: $reptileSkinRabbit = ReptileSkinDecorator(new Rabbit()); But I can't do this because I have two abstract methods in ReptileSkinDecorator class. They are: abstract public function setSleep($hours); abstract public function setEat($food); So, instead of just re-decorating only skin I also have to re-decorate setSleep() and setEat(); methods. But I don't need to. In all the book examples there is always ONLY ONE abstract method in Animal class. And of course it works then. But here I just made very simple real life example and tried to use the Decorator pattern and it doesn't work without implementing those abstract methods in ReptileSkinDecorator class. It means that if I want to use my example I have to create a brand new rabbit and implement for it its own setSleep() and setEat() methods. OK, let it be. But then this brand new rabbit has the instance of commont Rabbit I passed to ReptileSkinDecorator: $reptileSkinRabbit = ReptileSkinDecorator(new Rabbit()); I have one common rabbit instance with its own methods in the reptileSkinRabbit instance which in its turn has its own reptileSkinRabbit methods. I have rabbit in rabbit. But I think I don't have to have such possibility. I don't understand the Decarator pattern right way. Kindly ask you to point on any mistakes in my example, in my understanding of this pattern. Thank you.

  • ext4: error loading journal

    - by cloudyOutside
    I have an external hard drive with two partitions: A small FAT32 which is mostly empty and works fine and a large ext4 with tons of data, most of which isn't backed up. The ext4 is visible, but can't be mounted. I get an "error loading journal" error. The drive is a Western Digital Caviar Blue 500GB. Roughly 30GB of that is FAT32 and the rest is the ext4. The light on the enclosure turns red when reading from the bad partition. It was made by Cavalry. There wasn't any warning, but coincidentally, I've been thinking lately that I should get two large capacity drives for real backups. Is there anything that can be done? I'm not even sure I have enough storage to backup everything even if it is redeemable.

  • What is the best study guide for MCTS exam 70-562 ASP.NET 3.5 Application Development?

    - by jonsb
    The official "MCTS Self-Paced Training Kit (Exam 70-562): Microsoft .NET Framework 3.5 ASP.NET Application Development" will not be released until mid-April. For the time being, what is the best book with which to prepare for the exam? I'm not asking which book is the best ASP.NET 3.5 book in general, just which is best with regard to the skills measured on the exam. The book should focus on C#, not VB.

  • Routing from the DMZ to the interior network only

    - by Allan
    I have a home network connected to Verizon's FIOS service. Verizon's ActionTec router is connected to the ONT via coax to establish the MOCA network. My DD-WRT router's WAN port is connected to one of the ActionTec's LAN ports. The DD-WRT router is configured with a static IP address and assigned to the DMZ (this is done so I only have to configure port forwarding once). My issue is that this does not allow computers connected to the DD-WRT to serve streaming audio/video to the MOCA network using Verizon's Media Manager. I know that Media Manager uses ports 18001, 5050, and 5060, but I don't know how to forward those ports so that they are only available to the ActionTec's network and not the rest of the internet.

  • Setting up Multiple Routers (as Hardware Firewalls) behind a Home Router

    - by Synetech
    I’ve currently got one computer behind a router with built-in firewall functionality, connected to a home cable-modem that has a single Ethernet port and one IP. I’m going to have to set up another computer for the rest of the family to use which of course will need to be connected to the Internet, probably wirelessly since the modem is in my room and the new system would not be. What I would like to do is to get two more small routers with firewall capability and connect each computer to a router, which would in turn connect to the main router which connects to the cable-modem. That way, both systems have a hardware firewall protecting them (particularly the wireless system) and the burden of blocking would be reduced on both the computer CPUs and the main router because the secondary routers would handle some of the workload. I’m trying to find out about the complexities inherent in this design and how I could set it up to work, specifically the IP handling and NAT aspect. Thanks a lot.

  • How to get the pid of a running process using a single command that parse the output of ps?

    - by Sorin Sbarnea
    I am looking for a single line that does return the pid of a running process. Currently I have: ps -A -o pid,cmd|grep xxx|head -n 1 And this returns the fist pid, command. I need only the first number from the output and ignore the rest. I suppose sed or awk would help here but my experience with them is limited. Also, this has another problem, it will return the pid of grep if the xxx is not running. It's really important to have a single line, as I want to reuse the output for doing something else, like killing that process.

  • Is there some performance issue between leaving empty ListProperties or using dynamic (expando) prop

    - by indiehacker
    Is there a datastore performance difference between adding dynamic properties of the expando class when they are needed for an entity or the simpler (for me) framework of just setting up all possible properties I might need from the start even though most instances will just be left empty. In my specific case I would be having 5-8 empty ReferenceList properties as 'overhead' that will be empty when I skip using expando class.

  • Practical Experience using Stripes?

    - by Andrew Whitehouse
    I am coming from an Enterprise Java background which involves a fairly heavyweight software stack, and have recently discovered the Stripes framework; my initial impression is that this seems to do a good job of minimising the unpleasant parts of building a web application in Java. Has anyone used Stripes for a project that has gone live? And can you share your experiences from the project? Also, did you consider any other technologies and (if so) why did you chose Stripes?
