  • Confused with X.ORG version number

    - by caligula
    There is my trouble: I'm trying to install ATI drivers on my Dell Vostro 3350 laptop. On the AMD's site I followed steps to determine which driver should I use. After selecting what hardware I use I got a link to download amd-driver-installer-12-3-x86.x86_64.run and below was a description of that driver that it was compatible with X.Org version from 6.7 to 7.6. And I do not know what version of X.Org my Ubuntu uses. Cause after googling I found that version is 7.6 in Ubuntu 11.10. But after typing: X -version I got the output: X.Org X Server 1.10.4 Release Date: 2011-08-19 X Protocol Version 11, Revision 0 So what is the exact version of X.Org in Ubuntu 11.10 and how should one reliably determine it? Can anyone construe? Thanks.

  • Data Structure for Small Number of Agents in a Relatively Big 2D World

    - by Seçkin Savasçi
    I'm working on a project where we will implement a kind of world simulation where there is a square 2D world. Agents live on this world and make decisions like moving or replicating themselves based on their neighbor cells(world=grid) and some extra parameters(which are not based on the state of the world). I'm looking for a data structure to implement such a project. My concerns are : I will implement this 3 times: sequential, using OpenMP, using MPI. So if I can use the same structure that will be quite good. The first thing comes up is keeping a 2D array for the world and storing agent references in it. And simulate the world for each time slice by checking every cell in each iteration and further processing if an agents is found in the cell. The downside is what if I have 1000x1000 world and only 5 agents in it. It will be an overkill for both sequential and parallel versions to check each cell and look for possible agents in them. I can use quadtree and store agents in it, but then how can I get the information about neighbor cells then? Please let me know if I should elaborate more.

  • Anticipating JavaOne 2012 – Number 17!

    - by Janice J. Heiss
    As I write this, JavaOne 2012 (September 30-October 4 in San Francisco, CA) is just over a week away -- the seventeenth JavaOne! I’ll resist the impulse to travel in memory back to the early days of JavaOne. But I will say that JavaOne is a little like your birthday or New Year’s in that it invites reflection, evaluation, and comparison. It’s a time when we take the temperature of Java and assess the world of information technology generally. At JavaOne, insight and information flow amongst Java developers like no other time of the year.This year, the status of Java seems more secure in the eyes of most Java developers who agree that Oracle is doing an acceptable job of stewarding the platform, and while the story is still in progress, few doubt that Oracle is engaging strongly with the Java community and wants to see Java thrive. From my perspective, the biggest news about Java is the growth of some 250 alternative languages for the JVM – from Groovy to Jython to JRuby to Scala to Clojure and on and on – offering both new opportunities and challenges. The JVM has proven itself to be unusually flexible, resulting in an embarrassment of riches in which, more and more, developers are challenged to find ways to optimally mix together several different languages on projects.    To the matter at hand -- I can say with confidence that Oracle is working hard to make each JavaOne better than the last – more interesting, more stimulating, more networking, and more fun! A great deal of thought and attention is being devoted to the task. To free up time for the 475 technical sessions/Birds of feather/Hands-on-Labs slots, the Java Strategy, Partner, and Technical keynotes will be held on Sunday September 30, beginning at 4:00 p.m.   Let’s not forget Java Embedded@JavaOne which is being held Wednesday, Oct. 3rd and Thursday, Oct. 4th at the Hotel Nikko. It will provide business decision makers, technical leaders, and ecosystem partners important information about Java Embedded technologies and new business opportunities.   This year's JavaOne theme is “Make the Future Java”. So come to JavaOne and make your future better by:--Choosing from 475 sessions given by the experts to improve your working knowledge and coding expertise --Networking with fellow developers in both casual and formal settings--Enjoying world-class entertainment--Delighting in one of the world’s great cities (my home town) Hope to see you there!

    - by mloman
    I have dell laptop which does not have a numberpad, only a set of numbers above the qwerty layout. I want to be able to control the mouse cursor with my arrow keys. I activated the mouse keys by going to "System Setting" - "Universal Access" - "Pointing and Clicking" and activate "Mouse Keys" But still, I am unable to control the mouse cursor. How do I get this going so I don't have to take my hands off the keyboard?

  • Java chunk negative number problem

    - by user1990950
    I've got a tile based map, which is divided in chunks. I got a method, which puts tiles in this map and with positive numbers it's working. But when using negative numbers it wont work. This is my setTile method: public static void setTile(int x, int y, Tile tile) { int chunkX = x / Chunk.CHUNK_SIZE, chunkY = y / Chunk.CHUNK_SIZE; IntPair intPair = new IntPair(chunkX, chunkY); world.put(intPair, new Chunk(chunkX, chunkY)); world.get(intPair).setTile(x - chunkX * Chunk.CHUNK_SIZE, y - chunkY * Chunk.CHUNK_SIZE, tile); } This is the setTile method in the chunk class (CHUNK_SIZE is a constant with the value 64): public void setTile(int x, int y, Tile t) { if (x >= 0 && x < CHUNK_SIZE && y >= 0 && y < CHUNK_SIZE) tiles[x][y] = t; } What's wrong with my code?

  • Kernel source version number does not match

    - by user54557
    I am using Ubuntu 11.10. When I type 'uname -r' in the terminal, I get: 3.0.0-15-generic I want to download the kernel source for the particular kernel version I am running. When I look on kernel.org, and then look inside kernel.org/pub/linux/kernel/v3.0/ I can only find source tarballs by the name of linux-3.0.x.tar.gz. My 'uname -r' has an extra '0' in it. Am I looking in the wrong place? Is my kernel not a mainline one?

  • Why use other number bases when programming

    - by JMD
    My coworkers and I have been bending our minds to figuring out why anyone would go out of their way to program numbers in a base other than base 10. I suggested that perhaps you could optimize longer equations by putting the variables in the correct base you are working with (for instance, if you have only sets of 5 of something with no remainders you could use base 5), but I'm not sure if that's true. Any thoughts?

  • Finding maximum number of congruent numbers

    - by Stefan Czarnecki
    Let's say we have a multiset (set with possible duplicates) of integers. We would like to find the size of the largest subset of the multiset such that all numbers in the subset are congruent to each other modulo some m 1. For example: 1 4 7 7 8 10 for m = 2 the subsets are: (1, 7, 7) and (4, 8, 10), both having size 3. for m = 3 the subsets are: (1, 4, 7, 7, 10) and (8), the larger set of size 5. for m = 4 the subsets are: (1), (4, 8), (7, 7), (10), the largest set of size 2. At this moment it is evident that the best answer is 5 for m = 3. Given m we can find the size of the largest subset in linear time. Because the answer is always equal or larger than half of the size of the set, it is enough to check for values of m upto median of the set. Also I noticed it is necessary to check for only prime values of m. However if values in the set are large the algorithm is still rather slow. Does anyone have any ideas how to improve it?

  • Configuring trace file size and number in WebCenter Content 11g

    - by Kyle Hatlestad
    Lately I've been doing a lot of debugging using the System Output tracing in WebCenter Content 11g.  This is built-in tracing in the content server which provides a great level of detail on what's happening under the hood.  You can access the settings as well as a view of the tracing by going to Administration -> System Audit Information.  From here, you can select the tracing sections to include.  Some of my personal favorites are searchquery,  systemdatabase, userstorage, and indexer.  Usually I'm trying to find out some information regarding a search, database query, or user information.  Besides debugging, it's also very helpful for performance tuning.

  • Split large file, have arbitrary start index number

    - by nEJC
    I do a lot of file manipulation on my system and in one particular batch job I end up with around 16 Gb file. I need to prepare this data into smaller chunks for another process. I split it into 10k lines per file and numeric index, padded to 5 digits split -a 5 -d -l 10000 large_input_file /out_path/out. This way I end up with files named out.00000 out.00001 ... The problem is that this way indexing always starts with 0. Is there a way to set it to arbitrary starting index? man reveals nothing ...

  • PCI function number for SATA AHCI controller

    - by Look Alterno
    I'm debugging a second stage boot loader for a PC with SATA AHCI controller. I'm able to enumerate the PCI bus and find the hard disk. So far, so good. Now, lspci in my notebook (Dell Inspiron 1525) show me: -[0000:00]-+-1f.0 Intel Corporation 82801HEM (ICH8M) LPC Interface Controller +-1f.1 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller +-1f.2 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller \-1f.3 Intel Corporation 82801H (ICH8 Family) SMBus Controller My question: Is SATA AHCI Controller always function 2 in any PC? If not, how I found? I don't pretend to be general; booting my notebook will be good enough, without compromise further refinements.

  • See number of SVN Checkins per folder

    - by Farseeker
    I have a very large SVN repository (working copy of several gb) that has just reached its 20,000th checkin. As a bit of an interesting statistic for our team (and to partly celebrate our 20,000th checkin) I'd like to make a graph showing which folders in the repository have had the most checkins. Is there any way to do this? We mostly use integrated SVN clients in our IDE and Tortoise SVN, but I'm willing to get other tools for this one-off thing.

  • Number of iterations to real time

    - by Ivansek
    I have an animation of traffic. I have 20 cars in road network, each car have a starting node and end node. Each car know how much distance does it need to travel in order to reach the end node. I move cars each 20 ms for 10 px. To move all cars from their start node to end node I need 60 iterations. That is 60*20ms = 1200ms. Now I want to convert this time, or use data that I have, to a real time where car move 50km/h. How can I do that? Any idea?

  • What is the meaning of # in R5RS Scheme number literals

    - by ikmac
    There is a partial answer on Stack Overflow, but I'm asking something a teeny bit more specific than the answers there. So... Does the formal semantics (Section 7.2) specify the meaning of such a numeric literal? Does it specify the meaning of numeric operations on the value resulting from interpreting the literal? If yes, what are the meanings (in English -- denotational semantics is all greek characters to me :))?

  • Google analytics shows wrong number of page views, asp.net website

    - by f_karlsson
    Sometimes it can be for example 4500 requests, after a few hours it shows a few thousand less. What is wrong? It looks like analytics corrects itself. I changed from classic to Universal a few months ago, do not know if it has anything to do with this. In masterpage: <script> (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); ga('create', 'UA-xxxxxxxx-1', 'xxxxx.se'); ga('send', 'pageview'); </script>

  • Switch between apps with keyboard only (not ALT+TAB or SUPER+<number>)

    I'm looking for a way to switch between Apps with the keyboard only and not limited to some applications by defining shortcuts. Gnome3 offers the possibility to switch to (or start) an application by typing the app name. KDE allows this with krunner. The application lens in Unity does not offer this at all: https://bugs.launchpad.net/ayatana-design/+bug/1027792 Is there now way to master this very basic and handy functionality with Unity?
