  • So are we ever getting the technological singularity

    - by jsoldi
    I´m still waiting for an AI robot that will pass the Turing test. I keep going back to http://www.a-i.com/ and nothing. I don´t know much about AI but, did anyone ever tried to make a genetic algorithm whose evolution algorithm itself evolves? Or how about one whose algorithm that makes the genetic algorithm evolve, evolves? Or one whose genetic algorithm that makes the genetic algorithm that makes the genetic algorithm evolve, evolves? Or how about an algorithm that abstracts all this into a potentially infinitely deep tree of genetic evolution algorithms? Aren´t we just failing as programmers? And I don´t think we can blame the processors speed. If you make and application that simulates consciousness you will get a Nobel prize no matter how many hours it takes to respond to your questions. But nobody did it. It almost reminds me to Randi´s $1000000 paranormal challenge. As I keep going back to AI chat bots, they keep getting better at changing the subject on a way that seems natural. But if I tell them something like "if 'x' is 2 then whats two times 'x'?" then they don't have a clue what I'm talking about. And I don't think they need a whole human brain simulation to be able to answer to something like that. They don't need feelings or perception. This is just language and logics. I don't think my perception of the color red gives me the ability to understand that if 'x' is 2 then two times 'x' is 4. I'm sure we are just missing some elemental principle we cannot grasp because it's probably stuck behind our eyes. What do you think?

  • Never Miss An Important EMail/SMS With Vibration Notifier App

    - by Gopinath
    Worried about missing important emails/sms/missed calls as your mobile vibrates only once when you are away from mobile? Don’t worry! Vibration Notifier app is there to fix the problem on your Android phones. Author describes the app as “When you have a missed call or an unread SMS, the app keeps vibrating every X minutes for Y times or until you turn on the display of your device.” What is best with this app is that you can tweak as you like. Want your mobile to vibrate repeatedly for missed calls alone? You can just check Missed Calls option and un-check mails and SMS. You don’t want your mobile to vibrate forever? Configure to vibrate 5 times (or any other number) . You can even configure it to vibrate until the screen is unlocked. This looks like a very promising app for Android mobiles but the App is not yet available on Android Market. Developer has posted this app on XDA Developers Forum. Vibration Notifier | via Life Hacker This article titled,Never Miss An Important EMail/SMS With Vibration Notifier App, was originally published at Tech Dreams.

  • Crontab -e gives me error messages

  • Logarithmic spacing of FFT bins

    - by Mykel Stone
    I'm trying to do the examples within the GameDev.net Beat Detection article ( http://archive.gamedev.net/archive/reference/programming/features/beatdetection/index.html ) I have no issue with performing a FFT and getting the frequency data and doing most of the article. I'm running into trouble though in the section 2.B, Enhancements and beat decision factors. in this section the author gives 3 equations numbered R10-R12 to be used to determine how many bins go into each subband: R10 - Linear increase of the width of the subband with its index R11 - We can choose for example the width of the first subband R12 - The sum of all the widths must not exceed 1024 He says the following in the article: "Once you have equations (R11) and (R12) it is fairly easy to extract 'a' and 'b', and thus to find the law of the 'wi'. This calculus of 'a' and 'b' must be made manually and 'a' and 'b' defined as constants in the source; indeed they do not vary during the song." However, I cannot seem to understand how these values are calculated...I'm probably missing something simple, but learning fourier analysis in a couple of weeks has left me Decimated-in-Mind and I cannot seem to see it.

  • How do I deploy a charm from a local repository?

    - by Matt McClean
    I am trying to run the Charm tutorial from the juju documentation by creating a new charm from a local repository. I started by installing the charms from bzr to my local ubuntu 12.04 desktop running in a virtual machine. The new file structure is the following: ubuntu@ubuntu-VirtualBox:~$ find charms/precise/drupal/ charms/precise/drupal/ charms/precise/drupal/hooks charms/precise/drupal/hooks/db-relation-changed charms/precise/drupal/hooks/install charms/precise/drupal/hooks/start charms/precise/drupal/hooks/stop charms/precise/drupal/metadata.yml charms/precise/drupal/README When I install the mysql charm, which was downloaded from the remote charm repository, it works fine. However when I run the following command to deploy the new charm it fails with the following error message: ubuntu@ubuntu-VirtualBox:~$ juju deploy --repository=charms local:precise/drupal 2012-05-09 10:01:05,671 INFO Searching for charm local:precise/drupal in local charm repository: /home/ubuntu/charms 2012-05-09 10:01:05,845 WARNING Charm '.mrconfig' has an error: CharmError() Error processing '/home/ubuntu/charms/precise/.mrconfig': unable to process /home/ubuntu/charms/precise/.mrconfig into a charm Charm 'local:precise/drupal' not found in repository /home/ubuntu/charms 2012-05-09 10:01:06,217 ERROR Charm 'local:precise/drupal' not found in repository /home/ubuntu/charms Is there some file missing in the drupal charm directory that juju needs to make the charm valid? Also, I get the file processing error for the .mrconfig file also when deploying the mysql charm so is there something I need to change there perhaps?

  • What are some of the benefits of a "Micro-ORM"?

    - by Wayne M
    I've been looking into the so-called "Micro ORMs" like Dapper and (to a lesser extent as it relies on .NET 4.0) Massive as these might be easier to implement at work than a full-blown ORM since our current system is highly reliant on stored procedures and would require significant refactoring to work with an ORM like NHibernate or EF. What is the benefit of using one of these over a full-featured ORM? It seems like just a thin layer around a database connection that still forces you to write raw SQL - perhaps I'm wrong but I was always told the reason for ORMs in the first place is so you didn't have to write SQL, it could be automatically generated; especially for multi-table joins and mapping relationships between tables which are a pain to do in pure SQL but trivial with an ORM. For instance, looking at an example of Dapper: var connection = new SqlConnection(); // setup here... var person = connection.Query<Person>("select * from people where PersonId = @personId", new { PersonId = 42 }); How is that any different than using a handrolled ADO.NET data layer, except that you don't have to write the command, set the parameters and I suppose map the entity back using a Builder. It looks like you could even use a stored procedure call as the SQL string. Are there other tangible benefits that I'm missing here where a Micro ORM makes sense to use? I'm not really seeing how it's saving anything over the "old" way of using ADO.NET except maybe a few lines of code - you still have to write to figure out what SQL you need to execute (which can get hairy) and you still have to map relationships between tables (the part that IMHO ORMs help the most with).

  • Programming and Ubiquitous Language (DDD) in a non-English domain

    - by Sandor Drieënhuizen
    I know there are some questions already here that are closely related to this subject but none of them take Ubquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with a mixed languages. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options?

  • Does ssh key need to be named id_rsa?

    - by dustyprogrammer
    I have come across this problem a couple of times when creating build servers with keyed authentication. I was wondering if anyone else has experience this. I have a couple of keys for my current user that may connect to different machines. Let say machine1 and machine2. I have pasted my public key into their respective authorized_keys file. The first one I have named the first key id_rsa and the second key bender. When I try to connect to bender I get the following output with my verbose ssh connection debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/bozo/.ssh/.ssh/identity debug1: Trying private key: /home/bozo/.ssh/.ssh/id_rsa debug1: Trying private key: /home/bozo/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). It only offers the id_rsa key, as you can see above. Is this correct? If so why? How do I get it to offer more keys? I know it is a problem I see intermittently, because I at home I have multiple keys without much trouble. I would also appreciate a overview on how the pub and private keys interact with the client and server. I thought I had a pretty decent idea, but apparently I am missing something. Please and thank you.

  • Ubuntu 12.04 LTS: Error message "Failed to execute child process"

    - by Ron
    I am an Ubuntu-newbie and just started working with Ubuntu (version 12.04 LTS) a couple of days ago. I wanted to add a launcher icon to desktop for launching an application I previously installed. Up to now I can only launch it by typing setsid matlab -desktop into my terminal. Now there is the following problem with the execution via the desktop icon: Whenever I click the desktop icon, I get the following error message: "Failed to execute child process" I would like to add a screenshot, but unfortunately as a new user, I am not allowed to... In the main menu from where I added the icon via drag'n'drop to desktop there is also a permission to execute the .desktop file. I also tried to look for advice on the error message "Failed to execute child process..." but could not find anything useful. Now does anybody have an idea what I am missing? Sorry if this is a stupid question ;) ...but as I just said: I just started with Ubuntu... Thanks to everybody in advance for their help! :) And let me know if you should need any more information... Regards, Ron

  • How to change CapsLock key to produce "a"?

    - by Pit
    While typing I often hit the CapsLock key instead of the a key. (QWERTZU keyboard) This is quite annoying because the moment I realise that I hit the wrong key, I will have to delete multiple character/lines of text an rewrite them in the right form. I am searching for a way to prevent this. I have found a possibility to disable the CapsLock key in Keyboard Layout Options. But this would in my case mean that instead of writing an a I would write nothing. Positive - I don't have to rewrite a whole line, but only one character Negative - It's not that obvious that I hit the wrong key, as a missing character is not perceivable as an upper-case line of text. I would therefore prefer a possibility to map CapsLock to a . Thus when hitting CapsLock an a character would be written. Positive - If I hit CapsLock instead of a I get the output I actually wanted to type. Negative - If I hit CapsLock in any other context I will get an a character. As I don't ever intentionally use the CapsLock key this would not really pose a problem. (I think, or does it?) My Question: So how do I change to a ? And is there any case where this could be dangerous/provoke unwanted behaviour?

  • Change power button to 'Ask' in Xubuntu 13.10

    - by Gully.Moy
    I have recently installed Xubuntu 13.10 on my Vaio vpcea making me a Linux beginner. The problem is that laptop's power button is right on the edge of the bezel making it far too easy to press accidentally, in my opinion a design fault by Sony. At present, when I press the power button it shuts down strait away and as you can imagine, when I'm accidentally pressing it all the time it gets very annoying! So I planned to change it to ask what I would like to do when I press it or at least ask if I'm sure. So I went through the xfce GUI options "Settings Manager" - "Power Manager" to the field "When power button is pressed", but it was already set to "Ask". So I did some digging and found a thread telling me to navigate to /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml where it said to find power-button-action and check that value="3". It already did. So I looked some more and found this thread which focuses on acpi scripts. I tried solution 1 & 2 using sudoedit to change the files accordingly (I have made executable bash shell scripts already so I think I followed them correctly), but still no difference. I also found this thread which instructed me to edit /etc/systemd/logind.conf so that HandlePowerKey=ignore. Still no luck. I even tried my own approach to completely disable /etc/acpi/powerbtn.sh by renaming it powerbtn.sh.bak hoping for at least no response from the power button... and I have done many reboots in between... but still it shuts down! I have also read that some people have the file /etc/acpi/events/power_button, but I do not. So does anyone have any other ideas? What else could be executing the shutdown sequence Is there something I'm missing? I haven't undone any of these actions so every one of the above files is currently edited on my computer, with the exception that "Solution 2" automatically undone "Solution 1" above. Thanks guys.

  • Xfce gets really confused about session saving, etc

    - by Pointy
    I'm getting a new laptop running with 11.04 Ubuntu. I've got the xfce4 packages all installed, which is something I've had no problems with on any of my other machines. On this new laptop, however, though I can log in and use an xfce session without any problems, logging out of a session is problematic: I click the "Log out" widget from the panel and then "Log out" from its option dialog. Then the thing just sits there, not logging out. Subsequent attempts to open the "Log out" widget fail with an error about the session manager being busy. After maybe a minute or so, it logs out. Though I've got the "Save session" option checked in the log out dialog, xfce just makes a complete hash of the business. It does remember the applications that I had running, but it seems to forget about the window manager (!!) and the workspace configuration. I don't log in/out that often, and generally I don't care much about restarting applications, but the window manager being missing is of course pretty annoying. I like xfce because it's simple and unobtrusive and usually works pretty well. I've never experienced this, and I've got two other machines also running 11.04 with pretty much the same setup (straight Ubuntu install with xfce4 packages added). Is there some good way to diagnose stuff like that? edit — well I nuked my session cache, did an explicit save from the session widget, and now it works. Well, it doesn't save the workspace location for each client and instead opens them all up on the first workspace, but I think that may be because, in the session, xfwm4 is the last thing in the "Client" list, so before it's started all the other clients just pile up in the first (and only) workspace. I'm still curious about how exactly it gets so messed up. I certainly wasn't knowingly attempting anything fancy or unorthodox, though I may have done something fishy inadvertently.

  • Drawing particles as a smooth blob

    - by Nömmik
    I'm new to game/graphics development and I'm playing around with particles (in 2D). I want to draw particles close to each other as a blob, just as liquid/water. I do not want to draw big circles overlapping as the blob won't be smooth (and too big). I don't really know physics but I assume what I want is something looking similar to surface tension. I haven't been able to find anything on stackexchange or on Google (maybe I do not know the correct keywords?). So far I have found two possible solutions, but I am unable to find any concrete information about algorithms. One of them is to calculate the concave hull of particles I consider being a blob. I can calculate the blob by creating an equivalence class (on the relation "close to each other"). Strangely enough I haven't been able to find any algorithm explaining how to calculate the concave hull. Many posts (and among stackexchange) links to libraries or commercial products that do this (I need libraries to work in C#), but never any algorithm. Also this solution might have a problem with a circle of particles, which would not detect the empty space in the middle. While researching concave hull I stumbled upon something called alpha shapes. Which seems to be exactly what I want to do, however just as with concave hull I haven't found any source explaining how they actually work. I have found some presentation materials but not enough to go on. It's like a big secret everyone knows except me :-/ After calculating the concave hull or alpha shape I want to make it a Bézier curve to make it smooth and nice. Although I do find my approach a bit too complex, maybe I am trying to solve this the wrong way? If you can either suggest any other solution to my problem, or explain the pieces I am missing I would be very happy and grateful :-) Thanks.

  • Algorithm allowing a good waypoint path following?

    - by Thierry Savard Saucier
    I'm more looking into how should I implement this, either a tutorial or even the name of the concept I'm missing. I'm pretty sure some basic pathfinding algorithm could help me here, but I dont know which one ... I have a worldmap, with different cities on it. The player can choose a city from a menu, or click on an available cities on the world map, and the toon should walk over there. But I want him to follow a predefine path. Lets say our hero is on the city 1. He clicks on city 4. I want him to follow the path to city 2 and from there to city 4. I was handling this easily with arrow movement (left right top bottom) since its a single check. Now I'm not sure how I should do this. Should I loop threw each possible path and check which one leads me to D the fastest ... and if I do how do I avoid running in circle forever with cities 1-5-2 ?

  • How to distribute python GTK applications?

    - by Nik
    This is in correlation with the previous question I asked here. My aim is to create and package an application for easy installation in Ubuntu and other debian distributions. I understand that the best way to do this is by creating .deb file with which users can easily install my application on their system. However, I would also like to make sure my application is available in multiple languages. This is why I raised the question before which you can read here. In the answers that were provided, I was asked to use disutils for my packaging. I am however missing the bigger picture here. Why is there a need to include a setup.py file when I distribute my application in .deb format? My purpose is to ensure that users do not need to perform python setup.py to install my application but rather just click on the .deb file. I already know how to create a deb file from the excellent tutorial available here. It clearly shows how to edit rules, changelog and everything required to create a clean deb file. You can look at my application source code and folder structure at Github if it helps you better understand my situation. Please note I have glanced through the official python documentation found here. But I am hoping that I would get an answer which would help even a lame man understand since my knowledge is pretty poor in this regard.

  • does my js replace view?

    - by Milla Well
    I am writing a web application which is based on Codeigniter and jQuery. I primarily use ajax to call my controller functions and it turned out, that there are just 4 view*.php files, because most of my contoller functions return JSON data, which is processed in my jQuery. So my actual code is divided in kind of MVCC model: Codeigniter model (db, computations) Codeigniter controller (filtering, xss-cleaning, checking permissions, call model functions) jQuery controller (callback functions) jQuery view (adding/removing classes, appending elements,... ) So I violate the paradigm of not using the echo function in my Codeiginter controller and simply call echo json_encode($result); because it doesn't make any sense to me to create a view*.php file for one loc. Especially because all the regular view*.php stuff is covered in my jQuery view. I was wondering if I am missing something out, or if there is a way to integrate this jQuery-controller in my Codeigniter. I found some words on this topic, but this seems pretty handmade. Are there some neat solutions? Does a MVCC model make sense?

  • Auto update for application hosted on multiple servers on cloud

    - by mots_g
    I'm working on an application which will run on multiple Amazon EC2 instances. I wish to incorporate auto update feature for my application. The updater should update all the Ec2 instances. Also, there is a central server which governs the creation/termination of EC2 instances as per load. The central server creates a EC2 new instance from a pre-configured custom AMI (custom image which has our application pre-installed). Also, once there is an update, the pre-configured AMI needs to be updated too else it would create new instances which are not updated. Should the central server notify all the ec2 instances for an update and then the instances update themselves?Or should the application on Ec2 instance have a check for periodically updating themselves? Also how should the Amazon custom AMI be updated? Should a new instance be created from it, updated and then a new AMI be re-created and then new images be created from this AMI? What is the best way to incorporate an auto update feature for this architecture? The central server is written in Java and the application running on the cloud is written in C++. Is there a good framework available that can be used for this architecture? Please let me know on what I could be missing in the design and how it would help me to have a nice, extensible and fail safe auto update architecture. Thanks

  • How can I compare between web development technologies?

    - by Steve
    I would like experts to explain for me how can I compare between web development tools or technologies in order to be able to choose the right one. I'm tired from searching always in the regular way: X Technology vs Y Technology. I'm tired from peoples' biased opinions and usually I don't find a fair comparison. I have decided to put my question here about how can I compare them so you may identify to me the main standards for comparisons so I can compare them by myself and becoming able to choose the technology that is appropriate for the project I will develop. Note: in web development technologies I mean server side languages (e.g. PHP). One important requirement for me that can be defined as major one is cost efficiency and I mean that I don't care about the cost in the near future or the current cost, but what is more important for me is the cost in the future. If, for example, the site becomes one of the most 100 visited sites.   So, how can I compare the cost of different technologies for a future status of a site (such as being very famous site) so I can scale my option easily without missing a good technology like what happened with some sites when they chose not the most effective tool.

  • What is the best way to check if there is overlap between player and static, non-collidable items in bullet physic engine

    - by tigrou
    I'd like to add non collidable objects (eg: power ups, items, ...) in a game world using Bullet Physics Engine and to know if there is collision between player and them. Some info : there is a lot of items ( 1000), all are box shapes and they don't overlap. Here is things i have tried : btDbvt* bvtItems = new btDbvt(); //btDbvt is a hierachical AABB tree, used by Bullet foreach(var item ...) { btDbvtVolume volume = ... //compute item AABB; bvtItems->insert(volume, (void*)someExtraData); } Then, to find collisions between items and player : playerRigidBody->getAabb(min, max); btDbvtVolume playervolume = ... //compute player AABB bvtItems->collideTV(bvtItems->m_root, playervolume, *someCollisionHandler); This works fairly well (and its very fast), however, there is a problem : it only check items AABB against player AABB. That loss of precision is acceptable for items but not for player which is not a box. It would actually need another check to make sure player really collide with item but i don't know how to do this in Bullet. It would have been nice to have a function like this : playerRigidBody->checkCollisionWithAABB(); After doing trying that, I discovered that a btGhostObject exist and seems to have been made for that. I changed my code like this : foreach(var item...) { btCollisionObject* ghostObject = new btGhostObject(); ghostObject->setCollisionShape(boxShape); ghostObject->setCollisionFlags(ghostObject->getCollisionFlags() | btCollisionObject::CF_NO_CONTACT_RESPONSE); startTransform.setOrigin(...); //item position ghostObject->setWorldTransform(startTransform); dynamicsWorld->addCollisionObject(ghostObject, btBroadphaseProxy::SensorTrigger, btBroadphaseProxy:: CharacterFilter); } It also works ok, but there is a huge fps drop (almost ten times slower) which is not acceptable. Maybe there is something missing (forget set a flag) and Bullet is doing extra job for nothing or maybe all that ghostObjects are polluting broad phase and ghostObject is not the right thing for that. Any help would be appreciated.

  • unit/integration testing web service proxy client

    - by cori
    I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

  • Subsumption architecture vs. perceptual control theory

    - by Yasir G.
    I'm a new person to AI field and I have to research and compare 2 different architectures for a thesis I'm writing. Before you scream (homework thread), I've been reading on these 2 topics only to find that I'm confusing myself more.. let me first start with stating briefly what I know so far. Subsumption is based on the fact that targets of a system are different in sophistication, thus that requires them to be added as layers, each layer can suppress (modify) the command of the layers below it, and there are inhibitors to stop signals from execution lets say. PCT stresses on the fact that there are nodes to handle environmental changes (negative feedback), so the inputs coming from an environment go through a comparator node and then an action is generated by that node, HPCT or (Hierarchical PCT) is based on nesting these cycles inside each other so a small cycle to avoid crashing would be nested in a more sophisticated cycle that targets a certain location for example. My questions, am I getting this the right way? am I missing any critical understanding about these 2 models? also any idea where I can find simplified explanations for each theory (so far been struggling trying to understand the papers from Google scholar :< ) /Y
