  • How to implment the database for event conditions and item bonuses for a browser based game

    - by Saifis
    I am currently creating a browser based game, and was wondering what was the standard approach in making diverse conditions and status bonuses database wise. Currently considering two cases. Event Conditions Needs min 1000 gold Needs min Lv 10 Needs certain item. Needs fulfillment of another event Status Bonus Reduces damage by 20% +100 attack points Deflects certain type of attack I wish to be able to continually change these parameters during the process of production and operation, so having them hard-coded isn't the best way. All I could come up with are the following two methods. Method 1 Create a table that contains each conditions with needed attributes Have a model named conditions with all the attributes it would need to set them conditions condition_type (level, money_min, money_max item, event_aquired) condition_amount prerequisite_condition_id prerequisite_item_id Method 2 write it in a DSL form that could be interpreted later in the code Perhaps something like yaml, have a text area in the setting form and have the code interpret it. condition_foo: condition_type :level min_level: 10 condition_type :item item_id: 2 At current Method 2 looks to be more practical and flexible for future changes, trade off being that all the flex must be done on the code side. Not to sure how this is supposed to be done, is it supposed to be hard coded? separate config file? Any help would be appreciated. Added For additional info, it will be implemented with Ruby on Rails

  • A Fresh Start

    - by Laila
    As you may already be aware, I'm no longer responsible for the .NET Reflector newsletter. That publication is now in the very capable hands of the Reflector team. But fear not; starting in early April, I'll be launching a brand new .NET Newsletter, and I invite you to enjoy the very first edition by subscribing to our new mailing list, or by updating your Simple-Talk subscriptions, and joining the .NET Newsletter mailing list. With a fresh and snappy design (it might even be described as idiosyncratic. but I can say no more at this stage), we'll be making a brand new start. Each month, a member of my team (that's the Red Gate .NET team) will host the .NET Newsletter, bringing you the choicest cuts of breaking news, the very best .NET content from Simple-Talk, alongside details of hot upcoming events. To top it off, not only will you be among the first to get access to free resources (including free wall-charts, training videos and eBooks), but you'll also get exclusive access to betas, early access programs, and special offers. We can't wait to share the new design and exciting new content with you! If you have any questions about the changes to the newsletter, please feel free to send an email to [email protected] or post a comment on my blog. If I don't hear from you before next month, then I'll simply say that I hope you enjoy the new look. Cheers, Laila

  • Internet Explorer 9 auto "feeling lucky" for gmail bing search

    - by Gareth Jones
    When Im at school and using school computers, i have to use has IE9. When I want to access my gmail, I type in "gmail" in the URL bar, and thus IE9 does a bing search. The page half loads (As in, loads just about every thing but the search results) and then opens my gmail, kinda like google's "i'm feeling lucky". My question is this: Why? IE9 doesn't have the URL of gmail, as i can watch the bing search load, and then the url changes to gmail, and it only happens for Gmail, having tired with searching Google and Facebook in the same method. The computer is running Windows 7 with Windows Aero disabled, and limited account privileges. While its a cool thing, I would like to known what causes it to happen. Thanks

  • "The daemon is being inhibited" error message when mounting volumes on a partitioned external HD [closed]

    - by Todd
    I'm having a great deal of difficulty with an external hard drive. I'm currently running a dual boot system (XP Service Pack 3 and Ubuntu 11.04 Natty Narwahl) on a Dell Inspiron B120. I'm trying to set up a new 80 GB Hitachi external HD. Using GParted, I formatted the drive and set up the partitions. The partitioning scheme is as follows 10GB NTFS Primary, 2GB Linux-Swap Primary, 50GB FAT32 Primary, 12GB Unallocated. After applying those changes, I went into Disk Utility and the HD appears along with the correct partitions. When I try to mount the volumes for partitions 1 and 3, I get a pop-up stating: Error Mounting Volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. When I try to to check the filesystem I get a pop-up stating: Error Checking filesystem on volume An error occurred while performing an operation on "Home" (Partition 3 of HTS548080m9AT00): The daemon is being inhibited. Throughout the time that I'm attempting to troubleshoot the problem, the external drive light is on and blinking. With my frustration hitting a boiling point, I try to shut down the drive and remove it so that I can plug in a different external HD that works PERFECTLY. However, when I try to shut down and safely remove the drive, I get a pop-up stating: Error Detaching Drive An error occurred while performing an operation on "80GB Hard Disk" (HTS548080m9AT00): The daemon is being inhibited. Can anyone tell me what I'm doing wrong? I'm a newbie and not that skilled with terminal commands, so please dumb it down for me if you request specific command output.

  • How to rsync a large file, with as little CPU and bandwidth expense as possible?

    - by Johan Allgoth
    I have a 500 GB file that I plan on backing up remotely. The file changes often. I'll be rsyncing it from a desktop to a server. Both can run rsync client or server. What is the proper command for this? The ones I've tried sofar has been taking forever or simply acted strange. Example and results: rsync -cv --partial --inplace --no-whole-file /desktop/file1 myserver.com::module/file1 Seems to work, but only if I do it twice (?!). Also, slow. Does the above command do the checksumming on both computers, or only on the sending one? Is it correct otherwise?

  • Fiction that includes BASIC programs [closed]

    - by Clinton Blackmore
    Back in what must've been the mid-80s, when every microcomputer included BASIC and Choose Your Own Adventure Books were really popular, there were some novels that had BASIC programs listed in the text, for you to type in and further enjoy. For example, as I recall, in one of these books, the adventurers were infiltrating an undersea base (and eventually wiped the bad guy's data storage [I do believe it was a hard drive, even though they were uncommon then]). One of the programs involved a game were you piloted a submarine and had to avoid or shoot sharks. The code was in BASIC; minor changes (such as 'CLS' - 'HOME') had to be made for your specific computer, and it used good old 40-column text-mode to display the action. IIRC, the plot never depended upon the programs. My question is, does anyone else recall these sorts of books? Do you know any titles that I could look for, or of any online? I am toying with the idea of writing a story like this (no, not in BASIC!), and would really like to see how it was done, back in the day.

  • Separate tables or single table with queries?

    - by Joe
    I'm making an employee information database. I need to handle separated employees. Should I a. set up a query with a macro to send separated employees to a separate table, or b. just add a flag to the single table denoting separation? I understand that it's best practice to take choice b, and the one reason I can think of for this is that any structural changes I make to the table later will have to be done in both places. But it also seems like setting up a flag forces me to filter out that flag for basically every useful query I'm going to make in the future.

  • Outlook - Sychronise contacts from exchange

    - by THEMike
    At work the exchange server has details of all employees in the system. Then there is the Contacts folder in Outlook. I can populate this with all staff, but, I want to synchronise it against all staff (occasionally) removing people who in are in my local contacts, but not in the Exchange server (leavers) and importing changes/updates/new staff from the exchange server. However, I also have some personal contacts (family members etc) locally that I want to exclude from that. This is to enable synching to my smartphone better. Any suggestions? Regards, Michael

  • Bejeweled-like game, managing different gem/powerup behaviors?

    - by Wissam
    I thought I'd ask a question and look forward to some insight from this very compelling community. In a Bejeweled-like (Match 3) game, the standard behavior once a valid swap of two adjacent tiles is made is that the resulting matching tiles are destroyed, any tiles now sitting over empty spaces fall to the position above the next present-tile, and any void created above is filled with new tiles. In richer Match-3 games like Bejeweled, 4 in a row (as opposed to just 3) modifies this behavior such that the tile that was swapped is retained, turned into a "flaming" gem, it falls, and then the empty space above is filled. The next time that "flaming gem" is played it explodes and destroys the 8 perimeter tiles, triggers a different animation sequence (neighbors of those 8 tiles being destroyed look like they've been hit by a shockwave then they fall to their respective positions). Scoring is different, the triggered sounds are different, etc. There are even more elaborate behaviors for Match5, Match-cross-pattern, and many powerups that can be purchased, each which produces a more elaborate sequence of events, sounds, animations, scoring, etc... What is the best approach to developing all these different behaviors that respond to players' "move" and her current "performance" and that deviate from the standard sequence of events, scoring, animation, sounds etc, in such a way that we can always flexibly introduce a new "powerup" ? What we are doing now is hard-coding the events of each one, but the task is long and arduous and seems like the wrong approach especially since the game-designers and testers often offer (later) valuable insight on what works better in-game, which means that the code itself may have to be re-written even for minor changes in behavior (say, destroy only 7 neighboring tiles, instead of all 8 in an explosion). ANY pointers for good practices here would be highly appreciated.

  • Do you leverage the benefits of the open-closed principle?

    - by Kaleb Pederson
    The open-closed principle (OCP) states that an object should be open for extension but closed for modification. I believe I understand it and use it in conjunction with SRP to create classes that do only one thing. And, I try to create many small methods that make it possible to extract out all the behavior controls into methods that may be extended or overridden in some subclass. Thus, I end up with classes that have many extension points, be it through: dependency injection and composition, events, delegation, etc. Consider the following a simple, extendable class: class PaycheckCalculator { // ... protected decimal GetOvertimeFactor() { return 2.0M; } } Now say, for example, that the OvertimeFactor changes to 1.5. Since the above class was designed to be extended, I can easily subclass and return a different OvertimeFactor. But... despite the class being designed for extension and adhering to OCP, I'll modify the single method in question, rather than subclassing and overridding the method in question and then re-wiring my objects in my IoC container. As a result I've violated part of what OCP attempts to accomplish. It feels like I'm just being lazy because the above is a bit easier. Am I misunderstanding OCP? Should I really be doing something different? Do you leverage the benefits of OCP differently? Update: based on the answers it looks like this contrived example is a poor one for a number of different reasons. The main intent of the example was to demonstrate that the class was designed to be extended by providing methods that when overridden would alter the behavior of public methods without the need for changing internal or private code. Still, I definitely misunderstood OCP.

  • Configuring Nagios BGP plugin on Ubuntu

    - by user141610
    I am trying to configure nagios check_bgp_neighbors plug-in on Ubuntu and followed README file of check_bgp_neighbors plug-in. I have made following changes: define command{ command_name check_bgp_all command_line $USER1$/check_bgp_neighbors -H $HOSTADDRESS$ -C $USER3$ -n $ARG1$ -n $ARG2$ } to define command{ command_name check_bgp_all command_line /usr/local/nagios/libexec/check_bgp_neighbors.sh -H xx.xx.xx.49 -C xx.xx.xx.50 And define service{ use server-service hostgroup_name svc-bgp1 service_description BGP Check 1 check_command check_bgp_all!10.0.0.1!172.16.0.2 } to define service{ use generic-service hostgroup_name svc-bgp1 service_description BGP Check 1 check_command check_bgp_all!xx.xx.xx.50 } xx.xx.xx.49 is the IP of the host router and xx.xx.xx.50 is the IP of eBGP neighbour. After that it shows critical status. I know my command is not correct but cannot detect the problem. I learned that in this plug-in user-name and password of the host router are required but don't know how and where to provide it. Nagios log does not show any error message.

  • Terminal/Putty showing control characters (^M) after updating

    - by jaycee48
    I updated my system yesterday afternoon using the recommended updates from Update Manager. After it completed, I shutdown my system and went home for the day. I come in this morning and I am getting control characters displayed when using vi in both the standard terminal emulator, putty, and putty inside of my Windows virtual that I run with VirtualBox. I have made no other system changes and I cannot figure out how this occurred. It's as if every text file I have was created in DOS. I've searched the forums and I haven't found any answers. I am using xterm as my emulator and I checked with 3 of my coworkers and none of them are having this problem so we do not believe it is a server side issue. Especially since I've checked 3 different servers. There's nothing in my .profile other than PATH variables so I'm using the same terminal settings as everyone else. Some files are fine (I can open and read both /etc/environment and my .profile) but most of any kind of server generated log file is trash. Running cat or head on the same file displays the contents without the characters. Any ideas would be appreciated. Thanks.

  • Count function on tree structure (non-binary)

    - by Spevy
    I am implementing a tree Data structure in c# based (largely on Dan Vanderboom's Generic implementation). I am now considering approach on handling a Count property which Dan does not implement. The obvious and easy way would be to use a recursive call which Traverses the tree happily adding up nodes (or iteratively traversing the tree with a Queue and counting nodes if you prefer). It just seems expensive. (I also may want to lazy load some of my nodes down the road). I could maintain a count at the root node. All children would traverse up to and/or hold a reference to the root, and update a internally settable count property on changes. This would push the iteration problem to when ever I want to break off a branch or clear all children below a given node. Generally less expensive, and puts the heavy lifting what I think will be less frequently called functions. Seems a little brute force, and that usually means exception cases I haven't thought of yet, or bugs if you prefer. Does anyone have an example of an implementation which keeps a count for an Unbalanced and/or non-binary tree structure rather than counting on the fly? Don't worry about the lazy load, or language. I am sure I can adjust the example to fit my specific needs. EDIT: I am curious about an example, rather than instructions or discussion. I know this is not technically difficult...

  • VMware Kernel Module Updater hangs on Ubuntu 13.04

    VMware Player has a nice auto-detection of kernel changes, and requests the user to compile the required modules in order to load them. This happens from time to time after a regular update of your system. Usually, the dialog of VMware Kernel Module Updater pops up, asks for root access authentication, and completes the compilation. VMware Player or Workstation checks if modules for the active kernel are available. In theory this is supposed to work flawlessly but in reality there are pitfalls occassionally. With the recent upgrade to Ubuntu 13.04 Raring Ringtail and the latest kernel 3.8.0-21 the actual VMware Kernel Module Updater simply disappeared and the application wouldn't start as expected. When you launch VMware Player as super user (root) the dialog would stall like so: VMware Kernel Module Updater stalls while stopping the services Prior to version 5.x of VMware Player or version 7.x of VMware Workstation you would run a command like: $ sudo vmware-config.pl to resolve the module version conflict but this doesn't work anyway. Solution Instead, you have to execute the following line in a terminal or console window: $ sudo vmware-modconfig --console --install-all Those switches are (as of writing this article) not documented in the output of the --help switch. But VMware already documented this procedure in their knowledge base: VMware Workstation stops functioning after updating the kernel on a Linux host (1002411). Update As of today I had the first kernel upgrade to version 3.8.0-22 in Ubuntu 13.04. Don't even try it without vmware-modconfig...

  • setting up freedns with an existing domain

    - by romeovs
    I've been running a webserver off of a pc at a static IP succesfully for the past 5 months. recently however, I've moved into another appartment and my ISP only provides a dynamic IP (my IP changes from time to time). I'm not an internet genius but I was thinking to fix this by using a Dynamic DNS provider. So I got on the web and found freedns. I'm a bit confused about how to set up everything though. I've managed to succesfully install the IP updater daemon on my web server. Then, in my registrars control panel, I set the NS records to point at ns1 through ns4.afraid.org (removing the old NS records). I'm not certain what I should do with the A records though (for now they are still pointing to the old static IP address). I have A records for www, blog, irc, etc. but I cannot point them at my new IP address, because it isn't Could someone explain this in the clearest possible sense (perhaps elaborating on what happens at each step of the DNS process). I never really knew what the A records are for anyway. (note that I haven't really found any documentation at the freedns website, or on google)

  • May the file size returned by stat be compromised?

    - by codeholic
    I want to make sure that nobody changed a file. In order to accomplish that, I want not only to check MD5 sum of the file, but also check its size, since as far as I understand this additional simple check can sophisticate falsification by several digits. May I trust the size that stat returns? I don't mean if changes were made to stat itself. I don't go that deep. But, for instance, may one compromise the file size that stat returns by hacking the directory file? Or by similar means, that do not require superuser privileges? It's Linux.

  • oddities in interference of linux extened ACLs and 'regular' permissions

    - by abbot
    I've got some legacy code which checks that some file is read-only and readable only by it's owner, i.e. permissions set to 0400. I also need to give read-only access to this file to some other user on the system. I'm trying to set extended ACLs, but this changes 'regular' permission bits in a strange way also: $ ls -l hostkey.pem -r-------- 1 root root 0 Jun 7 23:34 hostkey.pem $ setfacl -m user:apache:r hostkey.pem $ getfacl hostkey.pem # file: hostkey.pem # owner: root # group: root user::r-- user:apache:r-- group::--- mask::r-- other::--- $ ls -l hostkey.pem -r--r-----+ 1 root root 0 Jun 7 23:34 hostkey.pem And after this the legacy code starts complaining that the file is group-readable (while it is actually not!) Is it possible to set the extended ACLs in such a way that some other user will also have read-only access, while the file will appear to have only 0400 'regular' permissions?

  • Check if current Command Prompt was launched as the Administrator

    - by Canadian Luke
    I am looking to write a script that takes user input, then makes system wide changes. I need this to be very generic, but simply put, at the top, I need it to check to see if it's being run 'As an Administrator'. If it's not, then I want to display a message to tell them that; if it is, I want it to continue on. Is there a constant way to verify this? I am not looking to start a new session as the Administrator, I just want to detect if it's currently run as admin

  • What is a correct/polite way to inherit from an abandoned open-source project for a new open-source project?

    - by Kabumbus
    My team just tried to contact some guys from an old open source project hosted on code.google.com. We told them that we'd like to join their project and commit to it — at least to some branch of it — but no one responded to us. We tried everyone, owners and committers; no one was in any way active, and no one replied. But we have some code to commit and we really would love to continue work on that project. So we need to create a new project. We came up with a name for it which is close to but not a duplicate of the name of the project we want to inherit from. How should we do our first commit, and what should the commit message be? Should we just copy their code to our repository with a comment like "we inherited this code, we found it here under such and such a license ... now we're upgrading it to this more/less strict license ..."? Or should we just use their code as our first commit, with updates saying "we inherited from ... we made such and such changes ..."?

  • mailsend not sending to (or qmail not receiving from) the same machine

    - by roman
    A web applications sends two emails: to the user of the webapp to the administrator the administrators mailbox (qmail) is on the same machine as the web application (php, apache, /usr/sbin/sendmail). email 1 works, email 2 sometimes doesn't work. I don't see any pattern in the mails that don't work. Also because I don't exactly know WHICH emails failed (since the email itself would be the only notification). email 2 looks like this: from: <[email protected]> #changes for each user to: <[email protected]> What could be the problem? Are rejected emails stored somewhere? (if they are rejected.. how do I check this?)

  • iptables: built-in INPUT chain in nat table?

    - by ughmandaem
    I have a Gentoo Linux system running linux 2.6.38-rc8. I also have a machine running Ubuntu with linux 2.6.35-27. I also have a virtual machine running Debian Unstable with linux 2.6.37-2. On the Gentoo and Debian systems I have an INPUT chain built into my nat table in addition to PREROUTING, OUTPUT, and POSTROUTING. On Ubuntu, I only have PREROUTING, OUTPUT, and POSTROUTING. I am able to use this INPUT chain to use SNAT to modify the source of a packet that is destined to the local machine (imagine simulating an incoming spoofed IP to a local application or just to test a virtual host configuration). This is possible with 2 firewall rules on Gentoo and Debian but seemingly not so on Ubuntu. I looked around for documentation on changes to the SNAT target and the INPUT chain of the nat table and I couldn't find anything. Does anyone know if this is a configuration issue or is it something that was just added in more recent versions of linux?

  • XAMPP: Access Forbidden!

    - by Yar
    I just installed a fresh XAMPP on OSX. Apache runs and I can see the splash page. I open the httpd.conf and I set both places that point to htdocs to someplace else, which results in Apache showing an "Access Forbidden!" message. I plugged my directory here: <Directory "/Applications/XAMPP/xamppfiles/htdocs"> and here: DocumentRoot "/Applications/XAMPP/xamppfiles/htdocs" Most files have permissions like -rw-r--r--, but even if I set the index.php using chmod 777 nothing changes. Strangely, I just did this whole thing with MAMP and had no problems serving that directory, but it was slow.

  • No Obvious Answer - Query-Strings and Javascript

    - by nchaud
    Say I have this main page /my-site/all-my-bath-soaps which lists all my products. It has a search filter text box that uses javascript to filter the products they want to see on that page (the URL doesn't change as they filter). Now from many other parts of the site I want to navigate to this products-page and see specific products. E.g. <a href="/my-site/all-my-bath-soaps?filter='Nivea-Soap'"> will go to /all-my-bath-soaps and apply javascript filtering to see just that product and hide all dom nodes for the other products. The problem is if the user changes the text in the filter from 'Nivea-Soap' to 'Lynx' the javascript will work fine and show the new products but the URL stays at ?filter='Nivea-Soap'. Is there anything I can do about this? Of course, I don't want to reload the page with a new query string every time they change the search criteria. Somehow it'd be great to move the ?filter=... criteria into POST data instead - but how can I do this with a link I don't know...

  • Developing momentum on open source projects

    - by sashang
    Hi I've been struggling to develop momentum contributing to open source projects. I have in the past tried with gcc and contributed a fix to libstdc++ but it was a once off and even though I spent months in my spare time on the dev mailing list and reading through things I just never seemed to develop any momentum with the code. Eventually I unsubscribed and got my free time back and uncluttered my mailbox. Like a lot of people I have some little open source defunct projects lying around on the net, but they're not large and I'm the only contributor. At the moment I'm more interested in contributing to a large open source project and want to know how people got started because I find it difficult while working full time to develop any momentum with the code base. Other more regular contributors, who are on the project full-time, are able to make changes at will and as result enter that positive feedback cycle where they understand the code and also know where it's heading. It makes the barrier to entry higher for those that come along later. My questions are to people who actively contribute to large opensource projects, like the Linux kernel, or gcc or clang/llvm or anything else with say a developer head count of more than 10. How did you get started? Was there a large chunk of time in your life that you just could dedicate to working on the project? I know in Linus's case he had a chunk of time (6 months) to get it started. What barriers to entry did you encounter? Can you describe the initial stages of the time spent with the project, from when you had little understanding of the code to when you understood enough to commit regularly. Thanks
