• Configuring sudo to work without password

  - by aidan

  I'm trying to configure sudo to allow all users to restart apache without having to enter a password. Security concerns aside, why isn't this working? I added the line to /etc/sudoers: %admin ALL=NOPASSWD: /usr/sbin/apache2ctl $sudo -l User aidan may run the following commands on this host: (root) NOPASSWD: /usr/sbin/apache2ctl (ALL) ALL $sudo /usr/sbin/apache2ctl [sudo] password for aidan: Thanks for any help.

• Administer postgres from PGAdmin on remote mac using ssh tunnel

  - by Aidan Ewen

  I've got PostgreSQL installed on a Ubuntu server and I'm trying to connect to that server using PGAdmin on a remote macbook. I've created an ssh tunnel - macbook:~postgres$ ssh -L 5423:localhost:5432 [email protected] And I can connect using psql on the macbook as expected - macbook:~ me$ psql -U postgres -p 5423 -h localhost ... postgres=# In the 'New Server Registration' window on PGAdminIII I'm entering the following credentials - Name - MyServer Host - localhost Port - 5423 Maintenance DB - postgres Username - postgres Password - <remote_postgres_password> However the connection fails - Error connecting to the server: FATAL: password authentication failed for user "postgres" Not sure what's going on here, these seem to be the same credentials I've used for psql.

• how to create 2D collision detection

  - by Aidan Mueller

  I would like to know the best or most effective way to test for 2D collision. I also can do AABBs but when you have a line, for example, that is rotated 45º, and it is really long. it will be hitting things when it shouldn't. I might be able to go through the pixels to see if they are touching others, but that might be slow if I had a big picture. and it might add some complications if I had a movie clip made of several images. How do I check collision between two Images? How would I do circle to box? Please help : ) PS: I do know java so you can write with java syntax and then use a made up GL

• Good resources for 2.5D and rendering walls, floors, and sprites

  - by Aidan Mueller

  I'm curious as to how games like Prelude of the chambered handle graphics. If you play for a bit you will see what I mean. It made me wonder how it works. (it is open-source so you can get the source on This page) I did find a few tutorials but I couldn't undertand some of the stuff but it did help with some things. However, I don't like doing things I don't understand. Does anyone know of any good sites for this kind of 2.5D? Any help is appreciated. After all I've been googling all day. Thanks :)

• On a queue, which end is the "head"?

  - by Aidan Cully

  I had always thought that the "head" of a queue as the next element to be read, and never really questioned that usage. So a linked-list library I wrote, which is used for maintaining queues, codified that terminology: we have a list1_head macro that retrieves the first element; when using this library in a queue, this will be the first element to be removed. But a new developer on the team was used to having queues implemented the other way around. He described a queue as behaving like a dog: you insert at the head, and remove at the tail. This is a clever enough description that I feel like his usage must be more widespread, and I don't have a similarly evocative description of my preferred usage. So, I guess, there are two related questions: 1, what does the "head" of a queue mean to you? and 2, why do we use the word "head" to describe that concept?

• (int) Math.floor(x / TILESIZE) or just (int) (x / TILESIZE)

  - by Aidan Mueller

  I have a Array that stores my map data and my Tiles are 64X64. Sometimes I need to convert from pixels to units of tiles. So I was doing: int x int y public void myFunction() { getTile((int) Math.floor(x / 64), (int) Math.floor(y / 64)).doOperation(); } But I discovered by using (I'm using java BTW) System.out.println((int) (1 / 1.5)) that converting to an int automatically rounds down. This means that I can replace the (int) Math.floor with just x / 64. But if I run this on a different OS do you think it might give a different result? I'm just afraid there might be some case where this would round up and not down. Should I keep doing it the way I was and maybe make a function like convert(int i) to make it easier? Or is it OK to just do x / 64?

• Is AGS outdated for Point & Click Adventures?

  - by Aidan Moore

  Is Adventure Game Studio (AGS) outdated? I am working on a Point and Click Adventure game being coded on the AGS engine, and just recently, the question of 'is this outdated?' has come up. I'll admit, AGS is a rather old, and kind of went out of style with the P&C genre itself, but I have not found anything quite like it that specializes in this specific format of games. So my big question is not only 'is this outdated?' but also 'Is there a better alternative?'

• Algorithm to reduce calls to mapping API

  - by aidan

  A random distribution of points lies on a map. This data lies behind an API, and I want to grab the complete set of points within a given bounding box. I can query the API with the bounding box and the API will return the set of points that fall within that box. The problem is that the API will limit the result set to 10 items, with no pagination and no indication if there are more points that have been omitted. So I made a recursive algorithm that takes a bounding box and requests the points that lie within it. If the result set is exactly 10 items, then I split the bounding box into four quadrants and recurse. It works fine but my question is this: if want to minimize the number of API calls, what is the optimal way to split the bounding box? Splitting it into quadrants was just an arbitrary decision. When there are a lot of points on the map, I have to drill down many levels before I start getting meaningful results. So I imagine it might be faster to split the box into, say, 9, 16, or more sections. But if I do that, then I eventually get to a point where a lot of requests are returning 0 results which isn't so efficient. Also, does the size of the limit on the results set affect the answer? (This is all assuming that I have no prior knowledge of nominal point density in the bounding box)

• java - how to split string in to multiple parts?

  - by Ewen

  I have a string that contains a value "firstword second third", and an ArrayList. I want to split the whole string in to by spaces and add the splitted strings in to the ArrayList. For example,"firstword second third" can be split to three separate strings and added three times in to the ArrayList. "1 2 3 4" can be splitted in to 4 strings and added 4 times in to the ArrayList. See the code below: public void separateAndAdd(String notseparated) { for(int i=0;i<canBeSepartedinto(notseparated);i++{ //what should i put here in order to split the string via spaces? thearray.add(separatedstring); } } public int canBeSeparatedinto(String string) //what do i put here to find out the amount of spaces inside the string? return .... } Please leave a comment if you dont get what I mean or I should fix some errors in this post. Thanks for your time!

• Problem passing strings with PHP post

  - by andy

  Hi Guys, Basically I'm developing a (very) simple search engine. You can enter a search term and you are taken to the results page - which works fine. However on the results page, I have a button that will take you to the next 10 results: where $term is the $_POST['term'] value. echo "<input type='hidden' name='term' value='" . $term . "'>"; This causes the following problem with the term is for example "aidan's". When the next 10 button is clicked, the term becomes aidan\ and no further results are found. I am not doing anything to $term. I usually use Java, but am required to use PHP for this uni assignment! Any help would be greatly appreciated.

• MySQL blocking new connections, and mysqladmin flush-hosts

  - by aidan

  I'm running MySQL on a remote server, and it suddenly started rejecting all connections: $ mysql -h 192.168.1.10 -u root -p ERROR 1129 (00000): Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' So, I try this flush-hosts command... $ mysqladmin flush-hosts -h 192.168.1.10 -u root -p mysqladmin: connect to server at '192.168.1.10' failed error: 'Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'' I.e. it's blocking the very un-blocking tool it recommends. Am I doing it wrong, or will I have to resort to ssh/cpanel/physical access?

• DNS resolution Windows 7 & browsing to locally hosted web site

  - by Aidan Whitehall

  We host two Intranet sites, http://intranet/ and http://sales.intranet/, both on the same server on the LAN. Local DNS (a Windows 2003 Server) was updated and both hostnames are configured to be CNAMEs that point to the FQDN name of the server on which they're hosted. On the LAN, Windows XP Professional clients can browse to both sites. However, Windows 7 Professional clients can browse to the main Intranet site, but not the Sales Intranet (neither using Firefox 3 nor Internet Explorer 8). Using nslookup on the command line on the Windows 7 boxes, intranet and sales.intranet both correctly resolve as CNAMEs of the server hosting them, and that in turn correctly resolves to the host's IP address. So the Q is... can anyone think why this might be, or what test to try next? Thank you for any suggestions!

• Write to windows share

  - by aidan

  I used to mount a windows share in Ubuntu server, with an entry in fstab: //data/SharedFolder /media/SharedFolder/ smbfs user,defaults,credentials=/root/.creds,uid=root,gid=root 0 0 /root/.creds is a text file with three lines, my username, password and domain. Users on the ubuntu server could write to this mount, but then I upgraded to 10.04 and now only root can write. Regular users can still read though. mount currently tells me: //data/SharedFolder on /media/SharedFolder type cifs (rw,mand,noexec,nosuid,nodev) How do I make it world writeable again? Thanks

• Enable re-attached mouse/keyboard via ssh?!

  - by aidan

  I had Ubuntu 9.10 x64 Desktop installed on a nettop I have (that I normally run headless), and yesterday I decided to take the plunge and update to 10.04. So, I plugged in a screen and usb mouse/keyboard, booted up and set to work. It was 1am, and it was telling me it had 3hrs left to install all the new packages, so I unplugged the screen and usb mouse/keyboard, left the box running, and went to bed. This evening, I plugged it all back in again to check progress. It's asking if I want to remove obsolete packages. I do, but neither the mouse nor keyboard work! I can access the box via SSH like I normally do; is there any way I can re-enable the keyboard from there? I'm reluctant to restart the box (via ssh) mid-way through such a complicated upgrade.

• Checkout repo from SVN but use local files to populate

  - by aidan

  I have an SVN server on our development server, and I release to our production server using rsync. It not ideal, but it's worked so far. Anyway, I've finally got the SVN client installed on the production server and I want to start using that to copy files from development to production. My problem is this, I don't want to check all the data out of development when I already have it on the production server. Is there a way to "checkout" a repository, but use the files that are already on the production server (and force it to assume they are the head versions for example)? Thanks.

• PC wont boot with more than 1 stick of RAM.

  - by Aidan

  Hi Guys, I've got the following computer and I've just put in a new CPU QX9650 and I've run into this problem since making this hardware change. Whenever I put more than 1 of my 4 sticks of ram into my machine it wont load an OS. It'll go through the BIOS but BSOD on windows load. It also wont let me install an OS from disk or boot into Linux. I've ran memtest with all 4 sticks in and I get 10k+ errors on test5. Each stick of ram on it's own is fine and functions properly. I only have problems when all 4 sticks are in the machine at the same time. System specs.. CPU: QX9650 Mobo: Asus P5B 2104 BIOS RAM: 2xPC25400 DDR2 , 2xPC2 6400 both OCZ. Is the problem on my end or is the CPU faulty?

• Android-Java: Constructing a triangle based on Coordinates on a map and your bearing

  - by Aidan

  Hi Guys, I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've got the math figured, I just have the triangle to construct. //UPDATE So I've figured out a good bit of this... Below is a method which takes in a long / lat value and attempts to compute a triangle finding a point 700 meters away and one to its left + right. It'd then use these to construct the triangle. It computes the correct longitude but the latitude ends up somewhere off the coast of east Africa. (I'm in Ireland!). public void drawtri(double currlng,double currlat, double bearing){ bearing = (bearing < 0 ? -bearing : bearing); System.out.println("RUNNING THE DRAW TRIANGLE METHOD!!!!!"); System.out.println("CURRENT LNG" + currlng); System.out.println("CURRENT LAT" + currlat); System.out.println("CURRENT BEARING" + bearing); //Find point X(x,y) double distance = 0.7; //700 meters. double R = 6371.0; //The radius of the earth. //Finding X's y value. Math.toRadians(currlng); Math.toRadians(currlat); Math.toRadians(bearing); distance = distance/R; Global.Alat = Math.asin(Math.sin(currlat)*Math.cos(distance)+ Math.cos(currlat)*Math.sin(distance)*Math.cos(bearing)); System.out.println("CURRENT ALAT!!: " + Global.Alat); //Finding X's x value. Global.Alng = currlng + Math.atan2(Math.sin(bearing)*Math.sin(distance) *Math.cos(currlat), Math.cos(distance)-Math.sin(currlat)*Math.sin(Global.Alat)); Math.toDegrees(Global.Alat); Math.toDegrees(Global.Alng); //Co-ord of Point B(x,y) // Note: Lng = X axis, Lat = Y axis. Global.Blat = Global.Alat+ 00.007931; Global.Blng = Global.Alng; //Co-ord of Point C(x,y) Global.Clat = Global.Alat - 00.007931; Global.Clng = Global.Alng; } From debugging I've determined the problem lies with the computation of the latitude done here.. Global.Alat = Math.asin(Math.sin(currlat)*Math.cos(distance)+ Math.cos(currlat)*Math.sin(distance)*Math.cos(bearing)); I have no idea why though and don't know how to fix it. I got the formula from this site.. http://www.movable-type.co.uk/scripts/latlong.html It appears correct and I've tested multiple things... I've tried converting to Radians then post computations back to degrees, etc. etc. Anyone got any ideas how to fix this method so that it will map the triangle ONLY 700 meters in from my current location in the direction that I am facing? Thanks, EDIT/// Converting the outcome to radians gives me a lat of 5.6xxxxxxxxxxxxxx .I have a feeling this bug has something to do with conversions but its not THAT simple. The equation is correct, it just.. outputs wrong..

• Sensor Manager getOrientation, doesnt display text and only works in debug mode?

  - by Aidan

  Hi Guys, My code appears to crash. I'm trying to setup a SensorManager for getting the Orientation of the device. I also have a listener that should update when conditions change. But when I run this code it crashes... public void sensor(){ // Locate the SensorManager using Activity.getSystemService sm = (SensorManager) getSystemService(SENSOR_SERVICE); sm.getOrientation(mR, mOrientation); // Register your SensorListener sm.registerListener(sl, sm.getDefaultSensor(Sensor.TYPE_ORIENTATION),SensorManager.SENSOR_DELAY_NORMAL); } private final SensorEventListener sl = new SensorEventListener() { @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { } @Override public void onSensorChanged(SensorEvent event) { if (event.sensor.getType()==Sensor.TYPE_ORIENTATION) { Global.Orientation = "Orientation is equal to: "+ SensorManager.getOrientation(mR, mOrientation); } } sm is defined as SensorManager sm; as a class wide variable also. I've got some other classes outputting the Orientation to a screen which I know works. The problem is somewhere in these methods. Am I doing it wrong or Is there a better way of doing this?

• Share functions between Crystal Reports without Crystal Reports Server?

  - by Aidan Ryan

  We have several reports that do the same formatting operations (e.g. displaying "PASS" or "FAIL" if a value is within a particular range.) Without Crystal Reports Server, is there a way to share functions between reports so that they do not need to be duplicated? I understand I could do this with a user function library but I would prefer not to port all of the crystal functions to UFL. Using Crystal Reports 2008.

• Switching Timezones in Perl's Template::Toolkit plugin Template::Plugin::Date

  - by aidan

  I have a calendar on my website, generated in Perl using Template::Toolkit and Template::Plugin::Date. It highlights the current day. I achieve this by iterating through all the dates (as I print the calendar) and comparing against the current date. Something like this: [% IF cur_date == date.format(format = '%Y-%m-%d') %] ... [% END %] It all works well until someone in Australia looks at it. (They are in a different timezone to me and my server in the UK). What's the best way to get Template::Plugin::Date to use a different time zone? It accepts a 'locale' parameter, but AFAIK this is only used for formatting.
