  • JUnit Custom Rules

    - by Jon
    JUnit 4.7 introduced the concept of custom rules: http://www.infoq.com/news/2009/07/junit-4.7-rules There are a number of built in JUnit rules including TemporaryFolder which helps by clearing up folders after a test has been run: @Rule public TemporaryFolder tempFolder = new TemporaryFolder(); There's a full list of built in rules here: http://kentbeck.github.com/junit/javadoc/latest/org/junit/rules/package-summary.html I'm interested in finding out what custom rules are in place where you work or what useful custom rules you currently use?

  • Custom inventory items based on inheritance

    - by Bogdan Marginean
    So, here's the scenario: I'm building an RPG. Like most of the other RPGs on the market, my game will feature an inventory and of course, inventory items. So far I've worked well with using a single class for all items, because I did not need anything else than character stat alteration on item usage (consumption). However, I'd like some items to have a more exotic effect. Think of something like when the user consumes a transformation potion, he automatically turns into a beast. In order to achieve this I've thought about declaring a new class that inherits from BaseItem for each item. Each descendant would override some methods (like void OnConsume()), to change the base behavior. This works fine, but when it comes to inventory management, I have some issues. The actual inventory will have to work with BaseItem components only (for obvious reasons, as it's an enumerable collection of objects of the same type); casting any descendant to the base class is possible, so no problems in adding items to the inventory. But how can I keep track of the descendant's type (class) for each item in the inventory? And how to perform the descendant's OnConsume from withint he inventory, for each item? Let me know if you can think of a better solution than mine, or if you can think of a solution to my problem only. Development is done in C#, inside Unity 3.5. Thanks!

  • Adding a custom option using an extension in Magento

    - by Tom
    I'm creating a custom extension and I would like to add a custom option when a certain item is purchased. For example, when the product "Name Tag" is purchased, the extension would detect that the specific product has been ordered and assign a custom option of "Year" to it. The user does not see this, but the attribute is added and displayed in the admin when viewing the order. Are there any specific listeners our there to accomplish this?

  • custom libindicator icon is not displayed

    - by Christoph Sterz
    Hi there, I want to change the statusicon of my own little reminder program. Currently I am using GTK.StatusIcon but I want to use a ApplicationIndicator. Therefore I created an own Icon and moved it to: /usr/share/icons/ubuntu-mono-dark/status/22 It is named indicator-notify.svg Heres the code for the icon. ind = appindicator.Indicator ("notify", "indicator-notify", appindicator.CATEGORY_APPLICATION_STATUS) ind.set_status (appindicator.STATUS_ACTIVE) This Icon is not displayed. Although every other icon from this folder is. What did I miss? Is there maybe the need to "register" the icon in GTK ?

  • E-commerce for custom orders/customer image upload

    - by ansarob
    We have a client that needs an e-commerce site set up pretty quickly. As I have no experience with e-commerce, I am looking for some guidance. Basically, the two big features we need are: Ability for customer to add info about order (example: the name the customer wants to be put on the customizable product they ordered) Ability for customer to upload photo of product to be customized I hope this makes sense. Right now I am really looking into Shopify, but I can't tell if it does everything we need. I know you can add order notes when checking out, but not sure about image upload (maybe it can be added as an app through the API?).

  • Custom field names in Rails error messages

    - by Madhan ayyasamy
    The defaults in Rails with ActiveRecord is beautiful when you are just getting started and are created everything for the first time. But once you get into it and your database schema becomes a little more solidified, the things that would have been easy to do by relying on the conventions of Rails require a little bit more work.In my case, I had a form where there was a database column named “num_guests”, representing the number of guests. When the field fails to pass validation, the error messages is something likeNum guests is not a numberNot quite the text that we want. It would be better if it saidNumber of guests is not a numberAfter doing a little bit of digging, I found the human_attribute_name method. You can override this method in your model class to provide alternative names for fields. To change our error message, I did the followingclass Reservation ... validates_presence_of :num_guests ... HUMAN_ATTRIBUTES = { :num_guests = "Number of guests" } def self.human_attribute_name(attr) HUMAN_ATTRIBUTES[attr.to_sym] || super endendSince Rails 2.2, this method is used to support internationalization (i18n). Looking at it, it reminds me of Java’s Resource Bundles and Spring MVC’s error messages. Messages are defined based off a key and there’s a chain of look ups that get applied to resolve an error’s message.Although, I don’t see myself doing any i18n work in the near-term, it is cool that we have that option now in Rails.

  • Why cache static files with Varnish, why not pass

    - by Saif Bechan
    I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

  • Setting up Cluster Configuration using an existing web server as a Primary Node?

    - by RapidWebs
    Thanks in advance for any help which is issued! I am having a slight issue, and need help with the decision making process when it comes to setting up my Cluster Configuration, consisting on a line of Ubuntu Servers (12.04). We currently have a Primary node, which resides in the US within a Datacenter, but we are going to be using this for all serious bandwidth and resource intensive websites, and through a configuration of Virtualmin + Webmin, will be setup as a sort of pseudo-cluster, using Virtualmins Cluster Modules. Anyways, on to the issue: We also have a business line setup locally, with three servers. here are their specs: Intel P4 2.4 ghz, 1GB Ram, 110 gb sata, Ubuntu 12.04* AMD 1.3 ghz, 512MB Ram, 20 GB IDE P3 Xeon 800mhz (dual physical processors), 1GB Ram, 3 * 25 GB Raid Configuration (one in use for host operating system). The first machine is currently IN USE and is serving virtual hosts off a sub-domain. My question is this: How can I integrate the Secondary node (which will be the Primary node per say, in this smaller configuration...) which is currently in use, into the cluster configuration w/ the other two servers for: Sharing Resources Redundancy (HA?) NFS /w the two Raid Disks without having the FORMAT the secondary node, and start fresh moving all my services in to a DRBD network drive or something similar, and than restoring all active virtualmin's Virtual hosts. the idea is that I want minimal downtime to people currently being served from server2.mywebsite.com, and from what I understand, all services need to be on a NFS so that they can be mounted on demand and accessed from the other machine taking over (i.e. Heartbeat + DRBD Config.) but my issue is that i already have all these services installed to their default directory structure: how can i most easily setup this NFS and HA system, move all my desires services to this new drive, and do it with minimal down time, and without breaking Virtualmin and everything else on my server? even just some pointers, a thread i could read, or a step by step check list or run down of commands i could issue to get started would be great! thanks!

  • Custom daemon script: works, but does not run at boot / startup

    - by pearjoint
    this is Ubuntu 10.10 Maverick. I have the following shell script in init.d that I want to run as a "daemon" (background service with start/stop/restart really) at system startup. There is a symlink in rc3.d. I tried 4 and 5 too. (Ideally this would initialize before graphical login happens and before a user logs in.) IMPORTANT: the script works 100% as expected and required when testing this with service MetaLeapDaemon start and service MetaLeapDaemon stop. (This shell script calls a Python program which makes sure the appropriate .pid files are both created at startup and deleted at exit.) So generally it works fine but now my only issue is why it will not be run at any of the run-levels I tried. I know for sure it isn't run because the log file it normally creates does not get created. As you can see (by the lack of any uid:gid args in the start-stop-daemon commands) this would currently run only under root, is this forbidden in a default setup? Here's the script, pretty much your run-off-the-mill daemon script really: #! /bin/sh DAEMON=/opt/metaleap/_core/daemon/MetaLeapDaemon.py NAME=MetaLeapDaemon DESC="MetaLeapDaemon" test -f $DAEMON || exit 0 set -e case "$1" in start) start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; stop) start-stop-daemon --stop --pidfile /var/run/$NAME.pid ;; restart) start-stop-daemon --stop --pidfile /var/run/$NAME.pid sleep 1 start-stop-daemon --start --pidfile /var/run/$NAME.pid --exec $DAEMON ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart}" >&2 exit 1 ;; esac exit 0

  • Apache2 VirtualHosts 403 Oddity

    - by Carson C.
    I'm sure this is something I should already understand, but I'm finding myself confused. The configs in play add up to this: NameVirtualHost *:80 Listen 80 <VirtualHost *:80> <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> </VirtualHost> <VirtualHost *:80> ServerAdmin [email protected] ServerName domain.tld ServerAlias *.domain.tld DocumentRoot /var/www/domain.tld <Directory /var/www/domain.tld> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> DNS is working correctly. The issue is, every variant of http://*.domain.tld/ (including http://domain.tld/) works correctly, except http://www.domain.tld/ which throws a 403. The logs state: client denied by server configuration: /etc/apache2/htdocs If I remove the first VirtualHost block from play, everything works as expected including http://www.domain.tld. This leads me to believe that for some reason, Apache is not considering www.domain.tld to match the second VirtualHost block, and is thereby falling back to deny all. This seems wrong. Shouldn't the second block match www.domain.tld? I've been able to resolve this, but I still don't understand why. In my original configs, I was using the real ip address of the server instead of *. Switching all instances to * as shown above made everything work as expected. Does this have something to do with the way browsers request resources?

  • Custom graph comparison?

    - by user57828
    I'm trying to compare two graphs using hash value ( i.e, at the time of comparison, try to avoid traversing the graph ) Is there a way to make a function such that the hash values compared can also lead to determining at which height the graphs differ? The comparisons between two graphs are to be made by comparing children at a certain level. One way to compare the graphs is have a final hash value for the root node and compare them, but that wouldn't directly reflect at which level the graphs differ, since their immediate children might be the same ( or any other case ).

  • RemoveHandler Issues with Custom Events

    - by Jeff Certain
    This is a case of things being more complicated that I thought they should be. Since it took a while to figure this one out, I thought it was worth explaining and putting all of the pieces to the answer in one spot. Let me set the stage. Architecturally, I have the notion of generic producers and consumers. These put items onto, and remove items from, a queue. This provides a generic, thread-safe mechanism to load balance the creation and processing of work items in our application. Part of the IProducer(Of T) interface is: 1: Public Interface IProducer(Of T) 2: Event ItemProduced(ByVal sender As IProducer(Of T), ByVal item As T) 3: Event ProductionComplete(ByVal sender As IProducer(Of T)) 4: End Interface Nothing sinister there, is there? In order to simplify our developers’ lives, I wrapped the queue with some functionality to manage the produces and consumers. Since the developer can specify the number of producers and consumers that are spun up, the queue code manages adding event handlers as the producers and consumers are instantiated. Now, we’ve been having some memory leaks and, in order to eliminate the possibility that this was caused by weak references to event handles, I wanted to remove them. This is where it got dicey. My first attempt looked like this: 1: For Each producer As P In Producers 2: RemoveHandler producer.ItemProduced, AddressOf ItemProducedHandler 3: RemoveHandler producer.ProductionComplete, AddressOf ProductionCompleteHandler 4: producer.Dispose() 5: Next What you can’t see in my posted code are the warnings this caused. The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.  Now, what on earth does that mean? Well, a quick Bing search uncovered a whole bunch of talk about delegates. The first solution I found just changed all parameters in the event handler to Object. Sorry, but no. I used generics precisely because I wanted type safety, not because I wanted to use Object. More searching. Eventually, I found this forum post, where Jeff Shan revealed a missing piece of the puzzle. The other revelation came from Lian_ZA in this post. However, these two only hinted at the solution. Trying some of what they suggested led to finally getting an invalid cast exception that revealed the existence of ItemProducedEventHandler. Hold on a minute! I didn’t create that delegate. There’s nothing even close to that name in my code… except the ItemProduced event in the interface. Could it be? Naaaaah. Hmmm…. Well, as it turns out, there is a delegate created by the compiler for each event. By explicitly creating a delegate that refers to the method in question, implicitly cast to the generated delegate type, I was able to remove the handlers: 1: For Each producer As P In Producers 2: Dim _itemProducedHandler As IProducer(Of T).ItemProducedEventHandler = AddressOf ItemProducedHandler 3: RemoveHandler producer.ItemProduced, _itemProducedHandler 4:  5: Dim _productionCompleteHandler As IProducer(Of T).ProductionCompleteEventHandler = AddressOf ProductionCompleteHandler 6: RemoveHandler producer.ProductionComplete, _productionCompleteHandler 7: producer.Dispose() 8: Next That’s “all” it took to finally be able to remove the event handlers and maintain type-safe code. Hopefully, this will save you the same challenges I had in trying to figure out how to fix this issue!
