  • RTS Movement + Navigation + Destination

    - by Oliver Jones
    I'm looking into building my own simple RTS game, and I'm trying to get my head around the movement of single, and multi selected units. (Developing in Unity) After much research, I now know that its a bigger task than I thought. So I need to break it down. I already have an A* navigation system with static obstacles taken into account. I don't want to worry about dynamic local avoidance right now. So I guess my first break down question would be: How would I go about moving mutli units to the same location. Right now - my units move to the location, but because they're all told to go to the same location, they start to 'fight' over one another to get there. I think theres two paths to go down: 1) Give each individual unit a separate destination point that is close to the 'master' destination point - and get the units to move to that. 2) Group my selected units in a flock formation, and move that entire flock group towards the destination point. Question about each path: 1a) How can I go about finding a suitable destination point that is close to the master destination? What happens if there isn't a suitable destination point? 1b) Would this be more CPU heavy? As it has to compute a path for each unit? (40 unit count). 2a) Is this a good idea? Not giving the units themselves a destination, but instead the flock (which holds the units within). The units within the flock could then maintain a formation (local avoidance) - though, again local avoidance is not an issue at this current time. 2b) Not sure what results I would get if I have a flock of 5 units, or a flock of 40 units, as the radius would be greater - which might mess up my A* navigation system. In other words: A flock of 2 units will be able to move down an alleyway, but a flock of 40 wont. But my nav system won't take that into account. I would appreciate any feedback. Kind regards, Ollie Jones

  • Apache Mod_rewrite rule working on one server, but not another

    - by Mason
    I am using mod_jk and mod_rewrite on httpd 2.2.15. I have a rule.... RewriteCond %{REQUEST_URI} !^/video/play\.xhtml.* RewriteRule ^/video/(.*) /video/play.xhtml?vid=$1 [PT] I just want to rewrite something like /video/videoidhere to /video/play.xhtml?vid=videoidhere This works perfectly on my developer machine, but on production I get a 404 (generated by Jboss, not Apache). here is the tail of access.log and rewrite.log on prod (broken). the rewrite.log is exactly the same on dev(working) applying pattern '^/video/(.*)' to uri '/video/46279d4daf5440b2844ec831413dcc3b' RewriteCond: input='/video/46279d4daf5440b2844ec831413dcc3b' pattern='!^/video/play\.xhtml.*' => matched rewrite '/video/46279d4daf5440b2844ec831413dcc3b' -> '/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b' split uri=/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b -> uri=/video/play.xhtml, args=vid=46279d4daf5440b2844ec831413dcc3b forcing '/video/play.xhtml' to get passed through to next API URI-to-filename handler "GET /video/46279d4daf5440b2844ec831413dcc3b HTTP/1.1" 404 420 "-" "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.6) Gecko/20100628 Ubuntu/10.04 (lucid) Firefox/3.6.6" I can access http://www.fivi.com/video/play.xhtml?vid=46279d4daf5440b2844ec831413dcc3b but not /video/46279d4daf5440b2844ec831413dcc3b Both server are even using the EXACT same httpd.conf, and modules.

  • UI Controls layer on top of operating system.

    - by Mason Blier
    I'm kind of curious about what layer writing a UI platform to the level of Win32 or the X Windowing System would fall in the grand scheme of an operating system. What layers below do they primarily make use of, is it heavily based on direct communication with the graphics card driver (I can't imagine going though a rendering pipeline like OpenGL for this), or is there a graphical platform as part of the operating system which extracts this out a little more. I'm also interested in the creation of shells and the like, and I"m particularly curious as to how people go about creating alternative shells for windows, what do people look for when figuring out what methods to call or what to hook into, etc? I guess I'm fairly lost at these concepts and finding it difficult to find documentation on them. I was initially excited to have taken Operating Systems in college but it was all low level resource management stuff. Thanks all, Mason

  • Windows 7 - How to access my documents from Windows 8 (dual boot)

    - by msbg
    I am dual booting Windows 7 and Windows 8 on two different partitions of the same drive: Win7: (C:) Win8: (D:) I am trying to get access to my Win7 user folder (C:\Users\Mason) in order to access my Win7 documents folder (C:\Users\Mason\Documents) from Windows 8. When I try to on Windows 8, I get an error message saying "You don't have permission to access this folder. Click here to permanently get access to this folder". When I click, the progress bar in Windows Explorer slowly moves to the maximum and disappears. When I try opening the folder, I get the same error message. When editing security permissions for the folder in Windows 8, Explorer freezes. I do not know how to remove the restrictions from Windows 7. I checked the Windows 8 user folder (D:\Users\Mason) and it had the group or user name: "S-1-5-21-936898901-3363470404-1273668825-1001". I tried copying and pasting it into the Win7 User Folder Permissions, but got the error "An object with the following name cannot be found". How would I access my folders?

  • SVN Authz - Any Subfolder permission or List contents

    - by Jaspa Jones
    Goal Basically I would like SVN users to be able to browse through a directory containing a lot of subfolders without allowing them to read its subfolders. [/] * = r [/Projects] * = # Allow viewing contents, but not reading. At least to be able to see Project1. [/Projects/Project1] my_group = rw Problem The problem is that there are a lot of projects. I could add every other project and make them disappear for the user, but that would be a lot of work to maintain. It would look like this: [/] * = r [/Projects] * = r [/Projects/Project1] my_group = rw [/Projects/Project2] * = [/Projects/Project3] * = [/Projects/Project4] * = [/Projects/Project5] * = It would be nice if I could use this: [/Projects/*] * = Any ideas? Thanks in advance, Jaspa Jones

  • Aggregating Excel cell contents that match a label [migrated]

    - by Josh
    I'm sure this isn't a terribly difficult thing, but it's not the type of question that easily lends itself to internet searches. I've been assigned a project for work involving a complex spreadsheet. I've done the usual =SUM and other basic Excel formulas, and I've got enough coding background that I'm able to at least fudge my way through VBA, but I'm not certain how to proceed with one part of the task. Simple version: On Sheet 1 I have a list of people (one on each row, person's name in column A), on sheet 2 I have a list of groups (one on each row, group name in column A). Each name in Sheet 1 has its own row, and I have a "Data Validation" dropdown menu where you choose the group each person belongs to. That dropdown is sourced from Sheet 2, where each group has a row. So essentially the data validation source for Sheet 1's "Group" column is just "=Sheet2!$a1:a100" or whatever. The problem is this: I want each group row in Sheet 2 to have a formula which results in a list of all the users which have been assigned to that group on Sheet 1. What I mean is something the equivalent of "select * from PeopleTab where GROUP = ThisGroup". The resulting cell would just stick the names together like "Bob Smith, Joe Jones, Sally Sanderson" I've been Googling for hours but I can't think of a way to phrase my search query to get the results I want. Here's an example of desired result (Dash-delimited. Can't find a way to make it look nice, table tags don't seem to work here): (Sheet 1) Bob Smith - Group 1 (selected from dropdown) Joe Jones - Group 2 (selected from dropdown) Sally Sanderson - Group 1 (selected from dropdown) (Sheet 2) Group 1 - Bob Smith, Sally Sanderson (result of formula) Group 2 - Joe Jones (result of formula) What formula (or even what function) do I use on that second column of sheet 2 to make a flat list out of the members of that group?

  • How many different servers are needed to keep a website running with no downtime? [closed]

    - by Mason Wheeler
    Machines go down. It's a fact of life. They may need to be rebooted for some reason, or they may have a hardware failure, or a power outage. So if I wanted to deploy a website with a server backed by a SQL database, putting the whole thing on one server wouldn't be good enough. It obviously needs at least two servers, so that if one goes down, the other can pick up the slack until the first comes back up. Of course, if I have the server software on two machines, either one of which could go down, I can't place the database on either of those two machines, because it could go down. So the database needs its own server. But that server can go down, so I need a backup database server and some sort of replication system to keep it in sync so the main can fail-over to it. So far, that's a bare minimum of 4 machines to keep one website running with a reasonable chance of no downtime. (Assuming no catastrophic events take place that take down both front-end servers at once or both DB servers at once, and no hacks, DDOS attacks, etc. Am I missing any other factors, or should I consider 4 servers to be the minimum for running a website with a goal of continuing operation without downtime even when a server goes down?

  • What's a good scheme for multi-user database synchronization?

    - by Mason Wheeler
    I'm working on a system to allow multiple users to collaborate on an online project. Everything is fairly straightforward, except for keeping the users in sync. Each user has their own local copy of the project database, which allows them to make changes and test things out, and then send the updates to the central server. But this runs into the classic synchronization question: how do you keep two users from editing the same thing and stomping each other's work? I've got an idea that should work, but I wonder if there's a simpler way to do it. Here's the basic concept: All project data is stored in a relational database. Each row in the database has an owner. If the current user is not the owner, he can read but not write that row. (This is enforced client-side.) The user can send a request to the server to take ownership of a row, which will be granted if the server's copy says that the current owner is NULL, or to release ownership when they're done with it. It is not possible to release ownership without committing changes to the server. It is not possible to commit changes to the server without having first downloaded all outstanding changes to the server. When any changes are made to rows you own, a trigger marks that row as Dirty. When you commit changes, the database is scanned for all Dirty rows in all tables, and the data is serialized into an update file, which is posted to the server, and all rows are marked Clean. The server applies the updates on its end, and keeps the file around. When other users download changes, the server sends them the update files that they haven't already received. So, essentially this is a reinvention of version control on a relational database. (Sort of.) As long as taking ownership and applying updates to the server are guaranteed atomic changes, and the server verifies that some smart-aleck user didn't edit their local database so they could send an update for a row they don't have ownership of, it should be guaranteed to be correct, and with no need to worry about merges and merge conflicts. (I think.) Can anyone think of any problems with this scheme, or ways to do it better? (And no, "build [insert VCS here] into your project" is not what I'm looking for. I've thought of that already. VCSs work well with text, and not so well with other file formats, such as relational databases.)

  • Windows 8: Everything from design, build, and how to sell a Metro style app

    - by Thomas Mason
    For me, there are a lot of similarities between an application developed for Windows Phone and a Metro style app developed for Windows 8. A Windows Phone 7 application (rather than an XNA game) is built in .NET and XAML against a subset of the .NET framework and the application has a lifecycle which needs to be conscious of battery life and so is split out into foreground/background pieces. The application is sandboxed in terms of its interactions with the local device and is packaged with a manifest which describes those interactions. The app needs to be aware of network connectivity status and its work on the network is done asynchronously to preserve the user experience.The app is packaged and deployed to a Marketplace which the user browses to find the app, read reviews, perhaps purchase it and then install it and receive updates over time. Quite a lot of those statements are as true of a Windows 8 Metro style app as they are for a Windows Phone app and so a Windows Phone app developer already has a good head start when it comes to building Metro style apps for Windows 8. With that in mind, there is an event to help developers with a Windows Phone app in Marketplace to begin the process of looking at Windows 8 and whether you can get a quick win by bringing your Phone application onto Windows. The idea of the event was to provide a space where developers can get together over 2 days and take the time out to look at what it means to take their app from Windows Phone to Windows 8. Kicking off on Saturday 16th June at 10am, we are told they have plenty of power sockets, WiFi, whiteboards, drinks, pizza, games, prizes and some quiet space that you can work in. Including people on hand with Windows Phone and Windows 8 experience to help everything along the way. There will be an attendee-voted schedule of talks but we’ll keep these out of your way if you just want to get on and code. We’ll also provide information around submitting your app to the Windows Store If you have a Windows Phone app in Marketplace, now’s a great time to look at getting it onto Windows 8. Sign up. Bring your laptop. Bring your app. Bring Windows 8 and Visual Studio 11. And everyone will their best to help you get your app onto Windows 8. Location & Venue TBA but it will be in central London, accessible by major railway and underground transportation. Day 1 Saturday 16th June 10am – 9pm Day 2 Sunday 17th June 10am – 4pm

  • How do I set up a "gateway" for a specific subdomain?

    - by Mason Wheeler
    I'm looking at setting up a website that will run a few different apps. Most of them can be managed by an Apache server, but I've got one specific thing that will run on a custom HTTP server. Looking around on apache.org, it looks like you can use mod_proxy to configure Apache to act as a "reverse proxy" and forward requests from a specific subdirectory to a new server with the ProxyPass directive. So if I wanted send anything from mysite.com/special on to the custom server, that's how I would do it. But what if I want to set it up as a subdomain instead? The documentation doesn't seem to cover that. If, I wanted to make it forward anything from special.mysite.com to the new server, how would I set that up?

  • Where does this concept of "favor composition over inheritance" come from?

    - by Mason Wheeler
    In the last few months, the mantra "favor composition over inheritance" seems to have sprung up out of nowhere and become almost some sort of meme within the programming community. And every time I see it, I'm a little bit mystified. It's like someone said "favor drills over hammers." In my experience, composition and inheritance are two different tools with different use cases, and treating them as if they were interchangeable and one was inherently superior to the other makes no sense. Also, I never see a real explanation for why inheritance is bad and composition is good, which just makes me more suspicious. Is it supposed to just be accepted on faith? Liskov substitution and polymorphism have well-known, clear-cut benefits, and IMO comprise the entire point of using object-oriented programming, and no one ever explains why they should be discarded in favor of composition. Does anyone know where this concept comes from, and what the rationale behind it is?

  • What's so difficult about SVN merges? [closed]

    - by Mason Wheeler
    Possible Duplicate: I’m a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS? Every once in a while, you hear someone saying that distributed version control (Git, HG) is inherently better than centralized version control (like SVN) because merging is difficult and painful in SVN. The thing is, I've never had any trouble with merging in SVN, and since you only ever hear that claim being made by DVCS advocates, and not by actual SVN users, it tends to remind me of those obnoxious commercials on TV where they try to sell you something you don't need by having bumbling actors pretend that the thing you already have and works just fine is incredibly difficult to use. And the use case that's invariably brought up is re-merging a branch, which again reminds me of those strawman product advertisements; if you know what you're doing, you shouldn't (and shouldn't ever have to) re-merge a branch in the first place. (Of course it's difficult to do when you're doing something fundamentally wrong and silly!) So, discounting the ridiculous strawman use case, what is there in SVN merging that is inherently more difficult than merging in a DVCS system?

  • JQuery Autocomplete - format listing and only return a part to the text box

    - by Jason
    I'm using the JQuery Autocomplete and it's working just fine. I'm using it to allow someone to search for users out of a database by searching on last name or id number. Right now the drop down list that is created is the resultes of a SQL query and looks something like: $row_rst['lName'] . ', ' . $row_rst['fName'] . " - " . $row_rst['user'] . "|" . $row_rst['id'] which outputs something like: Jones, Henry - hjones Gibbons, Peter - pgibbons When I pick Henry the text box gets Jones, Henry - hjones and the hidden field gets his id. I'd like to format the drop down in columns if possible and only return Jones, Henry to the text box if possible. Are either of those options possible? I'm thinking it has to do with either formatItem(row) or formatResult(row) but I'm not sure and I can't seem to find how to go about this.

  • SelectedValue which is invalid because it does not exist in the list of items

    - by Bob Jones
    I encounter this problem repeatedly, and haven't a clue what is causing it. I get an exception in the DataBind: "SelectedValue which is invalid because it does not exist in the list of items". Here are some important pieces of information: 1) I reload listOrgs periodically when the underlying data has changed. 2) The Organization.DTListAll call returns about 500 Int, String pairs. 3) There are no duplicate or null values in the returned data 4) After the first two lines below, listOrgs.Items.Count is 0, and the Selected Value is 0 5) The selected value when the DataBind operation executes is a value that is not in the set of ID values returned 6) All of the stuff I have found on line so far hasn't helped. 7) I am stumped! listOrgs.Items.Clear(); listOrgs.SelectedValue = "0"; listOrgs.DataSource = new Organization().DTListAll(SiteID); listOrgs.DataTextField = "OrganizationName"; listOrgs.DataValueField = "OrganizationID"; listOrgs.DataBind(); Bob Jones

  • How to measure the time HTTP requests spend sitting in the accept-queue?

    - by David Jones
    I am using Apache2 on Ubuntu 9.10, and I am trying to tune my configuration for a web application to reduce latency of responses to HTTP requests. During a moderately heavy load on my small server, there are 24 apache2 processes handling requests. Additional requests get queued. Using "netstat", I see 24 connections are ESTABLISHED and 125 connections are TIME_WAIT. I am trying to figure out if that is considered a reasonable backlog. Most requests get serviced in a fraction of a second, so I am assuming requests move through the accept-queue fairly quickly, probably within 1 or 2 seconds, but I would like to be more certain. Can anyone recommend an easy way to measure the time an HTTP request sits in the accept-queue? The suggestions I have come across so far seem to start the clock after the apache2 worker accepts the connection. I'm trying to quantify the accept-queue delay before that. thanks in advance, David Jones

  • How do I sort in solr by term frequency in multiple fields?

    - by user1488380
    I have been assigned a task that I should change our solr search to sort a list returned by solr by using the term frequency. Well, I´ve found a way to do so simply by using omitNorms="true". The problem is, that this won´t work when I am doing a field - search, say by name: q=name:jones Following this example I get a list of document whose term frequency is the highest for the "name" field. But What I wanted to achieve is to have a query that is giving my a list of documents whose term frequency is the highest for ALL fields. Example: If a User named Jones also has the word "Jones" in his biography 10 times I want that document ranked higher. Is that possible ?

  • Welcome to JavaOne!

    - by marius.ciortea
    Welcome to this year's JavaOne conference! We are glad you dropped by. We want to keep you informed of all the happenings around JavaOne: all the events leading up to the conference and all the events during the conference week itself. We'll cover announcements, news, planning (but we won't make you go to any meetings), and snafus (nothing that makes us look too bad, of course). We'll even throw in a contest or two to make sure you are paying attention. We'll post a couple of times a week, and then more frequently as we get closer to September. There's a group of us, and we cover the Java beat, JUGs, Oracle Technology Network, Oracle Solaris, and lots more. What do you want to hear about? Let us know.A group of us from the office went to see the movie Iron Man 2 (it just debuted in the United States) last week and it reminded us of Java, the Java community, and JavaOne. In all three cases, from many disparate (and sometimes seemingly incompatible) parts and people, something comes together that works, is cool, and helps make a better world. Right now, there are hundreds of little islands of planning, all busy answering questions for JavaOne: What sessions get selected? What goes in the Mason street tent (until a few weeks ago, Will there be a tent on Mason street?), What do the JUGS need? Which Oracle ACEs will be there? Can we do a surf theme at the OTN party? And, somehow, like an Iron Man suit, they all come together and work to make a great event. At least, we hope it will be great. That's for you to decide. Please don't be shy--give us your comments and suggestions. We'll be listening.P.S. You can attend Stark Expo online at Oracle.com/ironman2, where you can train to become a "Master Cloud Operative." I got my MCO certification. I wish I had a card to put in my wallet.

  • Using PHP OCI8 with 32-bit PHP on Windows 64-bit

    - by christopher.jones
    The world migration from 32-bit to 64-bit operating systems is gaining pace. However I've seen a couple of customers having difficulty with the PHP OCI8 extension and Oracle DB on Windows 64-bit platforms. The errors vary depending how PHP is run. They may appear in the Apache or PHP log: Unable to load dynamic library 'C:\Program Files (x86)\PHP\ext\php_oci8_11g.dll' - %1 is not a valid Win32 application. or Warning oci_connect(): OCIEnvNlsCreate() failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries Other than IIS permission issues a common cause seems to be trying to use PHP with libraries from an Oracle 64-bit database on the same machine. There is currently no 64-bit version of PHP on http://php.net/ so there is a library mismatch. A solution is to install Oracle Instant Client 32-bit and make sure that PHP uses these libraries, while not interferring with the 64-bit database on the same machine. Warning: The following hacky steps come untested from a Linux user: Unzip Oracle Instant Client 32-bit and move it to C:\WINDOWS\SYSWOW64\INSTANTCLIENT_11_2. You may need to do this in a console with elevated permissions. Edit your PATH environment variable and insert C:\WINDOWS\SYSTEM32\INSTANTCLIENT_11_2 in the directory list before the entry for the Oracle Home library. Windows makes it so all 32-bit applications that reference C:\WINDOWS\SYSTEM32 actually see the contents of the C:\WINDOWS\SYSWOW64 directory. Your 64-bit database won't find an Instant Client in the real, physical C:\WINDOWS\SYSTEM32 directory and will continue to use the database libraries. Some of our Windows team are concerned about this hack and prefer a more "correct" solution that (i) doesn't require changing the Windows system directory (ii) doesn't add to the "memory" burden about what was configured on the system (iii) works when there are multiple database versions installed. The solution is to write a script which will set the 64-bit (or 32-bit) Oracle libraries in the path as needed before invoking the relevant bit-ness application. This does have a weakness when the application is started as a service. As a footnote: If you don't have a local database and simply need to have 32-bit and 64-bit Instant Client accessible at the same time, try the "symbolic" link approach covered in the hack in this OTN forum thread. Reminder warning: This blog post came untested from a Linux user.
