  • The Uganda .NET Usergroup meeting for January 2011 - a look back.

    - by Malisa L. Ncube
    We had a very interesting meeting on Friday 28th last week. We had 10 attendees and two speakers. The first topic presented was Cloud Computing, presented by Allan Rwakatungu @arwakatungu who works with MTN Uganda. He gave a very brilliant outline of how Cloud computing and service oriented applications had begun changing the platform for operating business and the costs it saves because of scalability and elasticity. He went on to demonstrate the steps you would take if you are beginning a new Windows Azure project. He explained the history and evolution of the Windows Azure, SQL Azure and cloud services offered by Amazon and google.com. The attendees had many questions to ask (obviously), but they were all answered very well. We once again thank Allan, for taking time to prepare the presentation and demonstrating for us. We recorded a video on the entire presentation and after doing some editing we will publish it. One wish which was echoed by most members was that Microsoft should open the cloud services and development for Africa. Microsoft currently does not even have servers here in Africa and so far, that does not put African developers in the same platform as other developers in other continents. Now is the time considering the improvements in network speeds and joining of the Seacom network and broadband.   I presented on Parallelism and Multithreading using .NET 4.0, I also gave some details on the language changes in C# 5.0 and the async keyword and the TaskEx class. I explained the Task, Scheduling of parallel tasks and demonstrated problems that may arise from using parallelism inappropriately. I also demonstrated the performance improvements that may be achieved by taking advantage of multi-core processors. You may download the presentation on Parallelism and Multi-threading from here. The resolution of the meeting was that we should meet more than once a month and begin other activities which should be more fun. e.g. Geek Dinner, Geek Beer or CodeCamp. Based on that we all agreed we shall have a mid-month meeting starting from February. Cheers folks! del.icio.us Tags: .net,usergroup,cloud computing,parallelism,multi-threading

  • Calling the LWRP from the Exception Handler

    - by Sarah Haskins
    Is it possible to call out to a Provider (LWRP) from a Chef Exception Handler? I think my Provider is out of scope, but I don't know if what I am trying to do is possible? or advisable? Here is my provider code (cookbooks/config/provider/signal.rb): action :failure do Chef::Log.info("Yeah success") end Here is my exception handler code (exception_handler/handlers/exceptionHandler.rb): require 'chef/handler' config_signal "signal" do action :nothing end class Chef class Handler class LogCollector < Chef::Handler notifies :failure, resources(:config_signal => signal) end end end Also, if anyone has a good recommendation for general reading about scope in the context of Chef I'd appreciate it.

  • Architecture for a template-building, WYSIWIG application

    - by Sam Selikoff
    I'm building a WYSIWYG designer in Ember.js. The designer will allow users to create campaigns - think MailChimp. To build a campaign, users will choose an existing template. The template will have a defined layout. The user will then be taken to the designer, where he will be able to edit the text and style, and additionally change some layout options. I've been thinking about how best to go about structuring this app, and there are a few hurdles. Specifically, the output of the campaign will be dynamic: eventually, it will be published somewhere, and when the consumers (not my users, but the people clicking on the campaign that my user created) visit the campaign, certain pieces of data will change, depending on the type of consumer viewing the campaign. That means the ultimate output of the designer will be a dynamic site. The data that is dynamic for this site - the end product - will not be manipulated by the user in the designer. However, the data that will be manipulated by the user in the designer are things like copy, styles, layout options, etc. I'll call the first set of variables server-side data, and the second client-side data. It seems, then, that the process will go something like this: I'll need to create templates for this designer that have two dynamic segments. For instance, the server-side data could be Liquid expressions, and the client-side data Handlebars expressions. When the user creates a campaign, I would compile the template on the back end using some dummy data for the server-side variables, and serve up a handlebars template to the Ember app. The user would then edit the template, and the Ember app would save all his edits to the JS variables that were powering the template. This way he'd be able to preview the template. When he saves, he'll send back the selected template, along with all the data and options he's made. When it comes time to publish, the back-end system will have to do two things: compile the template with Handlebars using the campaign data, and then compile the template with Liquid using the server-side data Is my thinking roughly accurate about this, or is there a simpler way?

  • OpenID implementation - PHP, Javascript, MySQL

    - by Marc A.
    Hello, I've started doing some research on the technologies that I will need for my website. I'm trying to implement a really simple website with OpenID user registration. The website will store a block of text for each user. I imagine this means that I will need a database with: User ID Open ID url Data Having said that, I'm still having trouble deciding what I really need to do this. I know that I will need the following for the actual site: Javascript JQuery CSS But on the back end, I'm kind of lost at the moment. I've been looking at the OpenID-Selector, which is coded in Javascript. It seems like it's exactly what is used on this site. Will I actually need PHP? MySQL for the data and user registration? Thanks for the kickstart!

  • cloud programming for OpenStack in C / C++

    - by Basile Starynkevitch
    (Sorry for such a fuzzy question, I am very newbie to cloud programming) I am interested in designing (and developing) a (free software) program in C or C++ (probably, most of it being meta-programmed, i.e. part of the C code code being generated). I am still in the thinking / designing phase. And I might perhaps give up. For reference, I am the main architect and implementor of GCC MELT, a domain specific language to extend the GCC compiler (the MELT language is translated to C/C++ and is bootstrapped: the MELT to C/C++ translator being written in MELT). And I am dreaming of extending it with some cloud computing abilities. But I am a newbie in cloud computing. (I am only interested in free-software, GPLv3 friendly, based cloud computing, which probably means openstack). I believe that "compiling on the cloud with some enhanced GCC" could make sense (for super-optimizations or static analysis of e.g. an entire Linux distribution, or at least a massive GCC compiled free software like Qt, GCC itself, or the Linux kernel). I'm dreaming of a MELT specific monitoring program which would store, communicate, and and enhance GCC compilation (extended by MELT). So the picture would be that each GCC process (actually the cc1 or cc1plus started by the gcc driver, suitably extended by some MELT extension) would communicate with some monitor. That "monitoring/persisting" program would run "on the cloud" (and probably manage some information produced by GCC e.g. on NoSQL bases). So, how should some (yet to be written) C program (some Linux daemon) be designed to be cloud-friendly? So far, I understood that it should provide some Web service, probably thru a RESTful service, so should use an HTTP server library like onion. And that OpenStack is able to start (e.g. a dozen of) such services. But I don't have a clear picture of what OpenStack brings. So far, I noticed the ability to manage (and distribute) virtual machines (with some Python API). It is less clear how can it distribute some ELF executable, how can it start it, etc. Do you have any references or examples of C / C++ programming on the cloud? How should a "cloud-friendly" (actually, OpenStack friendly) C/C++ server application be designed?

  • Users in ubuntu; Cant figure it out

    - by Camran
    I am the only one who will have access to my website. Just installed my VPS and managed to get most stuff working. However, stuck on the "members" part. Currently, everything has been done as "root". I have read posts that I should create a user, because root isn't ideal. I have found thousand guides on how to create a user, but now what to do next. 1- Should I create a user with adduser username and then add the user to a group? But which group? 2- And will the user then be able to do everything as I have done logged on as "root"? 3- And somebody plz explain what "sudo" has to do with this? (if anything at all) Thanks

    - by jiewmeng
    I am entering uni soon. I can sit for a placement test to see if I elegible for exemptions. The details are http://www.comp.nus.edu.sg/undergraduates/TestScope11_12.html Or CS2100 Computer Organisation (please click title) The objective of this module is to familiarise students with the fundamentals of computing devices. Through this module students will understand the basics of data representation, and how the various parts of a computer work, separately and with each other. This allows students to understand the issues in computing devices, and how these issues affect the implementation of solutions. Topics covered include data representation systems, combinational and sequential circuit design techniques, assembly language, processor execution cycles, pipelining, memory hierarchy and input/output systems. Recommended Textbooks Digital Design: Principles and Practices [DDPP] by John F. Wakerly, Prentice-Hall. ISBN 0-13-324500-4. Computer Organizations and Design (The hardware/software interface) by David A. Patterson and John L. Hennessy. CS2105 Introduction to Computer Networks (please click title) This course aims to provide a broad introduction to computer networks and some appreciations of network application programming. It covers a range of topics including basic data communication and computer network concepts, protocols, networked computing concepts and principles, network applications development and network security. The emphasis of teaching is on the working principles and application of computer networks. As an integral part of the course, tutorials and practical assignments enforcing learning will also be given. These assignments provide an early exposure in network application programming and they should be able to complete by using personal computers and school's network facilities. Topics included: An overview of computer networks and the Internet Basic data communications Application layer Transport layer Network layer and routing Link layer and local area networks Recommended Textbook James F. Kurose & Keith W. Ross, Computer networking: A top-down approach featuring internet, Addison Wesley, 2001 I am wondering what resources eg. MIT OpenCourseWare or other universities resources are available to help he perpare for these particular modubles. I am thinking does the Networking one look like CCNA? The computer oragization. Its like electronics, assembly etc? I learnt some electronics in Poly but looking at the sample papers, uni looks very different... I have about 1 month to prepare if I want any chance of exempting from these modules :) any help?

  • L'essor du Cloud freiné par l'organisation des entreprises et non par la défiance envers la technologie selon IDC et VMWare

    L'adoption du Cloud serait freinée par l'organisation des entreprises Et non par la défiance vis-à-vis de la technologie selon IDC et VMWare Ce seraient les mentalités au sein des départements informatiques et non le manque de confiance dans la technologie qui freineraient l'adoption du Cloud Computing public, selon le livre blanc publié par IDC et sponsorisé par VMware.

  • RPi and Java Embedded GPIO: Hooking Up Your Wires for Java

    - by hinkmond
    So, you bought your blue jumper wires, your LEDs, your resistors, your breadboard, and your fill of Fry's for the day. How do you hook this cool stuff up to write Java code to blink them LEDs? I'll step you through it. First look at that pinout diagram of the GPIO header that's on your RPi. Find the pins in the corner of your RPi board and make sure to orient it the right way. The upper left corner pin should have the characters "P1" next to it on the board. That pin next to "P1" is your Pin #1 (in the diagram). Then, you can start counting left, right, next row, left, right, next row, left, right, and so on: Pins # 1, 2, next row, 3, 4, next row, 5, 6, and so on. Take one blue jumper wire and connect to Pin # 3 (GPIO0). Connect the other end to a resistor and then the other end of the resistor into the breadboard. Each row of grouped-together holes on a breadboard are connected, so plug in the short-end of a common cathode LED (long-end of a common anode LED) into a hole that is in the same grouping as where the resistor is plugged in. Then, connect the other end of the LED back to Pin # 6 (GND) on the RPi GPIO header. Now you have your first LED connected ready for you to write some Java code to turn it on and off. (As, extra credit you can connect 7 other LEDs the same way to with one lead to Pins # 5, 7, 11, 13, 15, 19 & 21). Whew! That wasn't so bad, was it? Next blog post on this thread will have some Java source code for you to try... Hinkmond

  • Grub2 : Windows 7 can't boot installing with Ubuntu 10.04 on different hard drive

    - by dellphi
    I use a dual boot with two hard disks and two OS is Ubuntu 10.04 and Windows 7. Windows 7 installed on the first disk, first partition. Grub is installed on a second hard disk MBR, and Ubuntu installed on an extended partition on a second hard drive.

  • How to disable automatic login?

    - by iammilind
    I was playing around with "User accounts" and somehow set automatic login. Now, when I start my PC, it just has one button named as "login". Clicking that button, directly logs me in to my PC. There is no music or no asking for password while logging in. As a side effect, it asks me separately for keyring password How to disable auto login and make login/keyring password unified again like before? NOTE: Attempting to disable Automatic Login from System Settings User Accounts does not work. This is the content of my /etc/lightdm/lightdm.conf (where I have commented the autologin for my username mgandhi): [SeatDefaults] greeter-session=unity-greeter user-session=ubuntu #autologin-user=mgandhi

  • Customizing the windows server 2008 RDP login screen possible?

    - by moontear
    Hi, I'm working with RDP sessions quite frequently. As we work in teams and all use the same user account on a particular computer (I know...) I was wondering if there was a way to display from which computer (hostname, computername) the person is connecting. The login screen I get when two users are already connected looks like this (german): I'd love it, if the screen would display from where the logged in user is connecting e.g. "COMPUTER\user connected from MYCOMPUTERNAME". This way I would know whom to ask to disconnect so I can hop onto the session. If I remember correctly the login screen looked different for previous Windows versions including this connection information. Any way I can easily enable this or is this just standard windows behavior and there is no way to tell from where the user is connecting (btw: Task Manager shows the computername of the connected user).

  • Automatically triggering standard spaceship controls to stop its motion

    - by Garan
    I have been working on a 2D top-down space strategy/shooting game. Right now it is only in the prototyping stage (I have gotten basic movement) but now I am trying to write a function that will stop the ship based on it's velocity. This is being written in Lua, using the Love2D engine. My code is as follows (note- object.dx is the x-velocity, object.dy is the y-velocity, object.acc is the acceleration, and object.r is the rotation in radians): function stopMoving(object, dt) local targetr = math.atan2(object.dy, object.dx) if targetr == object.r + math.pi then local currentspeed = math.sqrt(object.dx*object.dx+object.dy*object.dy) if currentspeed ~= 0 then object.dx = object.dx + object.acc*dt*math.cos(object.r) object.dy = object.dy + object.acc*dt*math.sin(object.r) end else if (targetr - object.r) >= math.pi then object.r = object.r - object.turnspeed*dt else object.r = object.r + object.turnspeed*dt end end end It is implemented in the update function as: if love.keyboard.isDown("backspace") then stopMoving(player, dt) end The problem is that when I am holding down backspace, it spins the player clockwise (though I am trying to have it go the direction that would be the most efficient at getting to the angle it would have to be) and then it never starts to accelerate the player in the direction opposite to it's velocity. What should I change in this code to get that to work? EDIT : I'm not trying to just stop the player in place, I'm trying to get it to use it's normal commands to neutralize it's existing velocity. I also changed math.atan to math.atan2, apparently it's better. I noticed no difference when running it, though.

  • Standard Network Tiers in a Distributed N-Tier System

    Distributed N-Tier client/server architecture allows for segments of an application to be broken up and distributed across multiple locations on a network.  Listed below are standard tiers in a Distributed N-Tier System. End-User Client Tier The End-User Client is responsible for sending and receiving requests from web servers and other applications servers and translating the responses so that the End-User can interpret the data effectively. The primary roles for this tier are to communicate with servers and translate server responses back to the end-user to interpret. Business-Specific Functions Validate Data Display Data Send Data to Webserver Web Server Tier The Web server tier processes new requests for information coming in from the HTTP and HTTPS ports. This primarily handles the generation of user interfaces and calls the application server when needed to access Data and business logic when needed. Business-specific functions Send Data to application server Format Data for Display Validate Data Application Server Tier The application server stores and executes predefined business logic that is applied to various pieces of data as the business determines.

  • RESTful API design - should a PUT return related data?

    - by alexmcroberts
    I have an API which allows a user to update their system status; and a separate call to retrieve system status updates from other users. Would it make sense to unify them under a PUT request where a user would request a PUT update with their own status update, and they would receive the status updates of other users? My solution would allow the PUT request to call the GET request method internally. The reason behind this is that when a user updates their system status they should be informed of other users status immediately, and I don't feel that having 2 seperate requests is necessary - and should be optional. I intend to keep the GET request for other users status as a status update for a user is not necessarily required in order to retrieve other users status', but once they update their own status is it vital that they get information about other users.

  • Cannot login via Unity login screen after upgrade to 12.04

    - by codesurgeon
    Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message - my user account and credential verification seem to be OK. I suppose that my individual graphics configuration causes problems ... I'm not sure how to reset that. I've tried stopping the UI via sudo service lightdm stop executed sudo nvidia-xconfig and restarted the UI sudo service lightdm start to no avail. My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07. Anybody have an idea how to get this fixed? Your help is appreciated :)

  • Error accessing other groups files in apache

    - by Shashank Jain
    I am using Cloud9 IDE on my server, which creates files with default permission 640. As a result when I try to open those file via HTTP, apache shows permission denied error. When IDE is running as root user, files created belong to root:root. Also, when I see as what user is apache running, all its processes are shown to be running as root user. I cannot understand why still it cannot access files. I know if I add apache's user to group of file owner, it will work. But, I don't know which user to add. PS: I don't want to change permission of each file I create. I want less troubling solution.

  • Root access issues - how do others manage this?

    - by Ciaran Archer
    Hi there I use my Ubuntu 10.04 LTS instance (via Virtual Box on Windows 7) with a non-root user. I am trying out developing Rails applications and I notice that I need to run some rails commands with sudo. The problem this gives me is some files are created by the root user then, and I cannot edit them via a GNOME window with my logged in user. What is the correct thing to do here? Should I somehow always login as root? If so how? Is there some way for me to give all files under my home directory (where I do all my Rails work) the correct permissions for all users, so I can edit them with my logged in user via a window? At the moment I have to resort to opening a file via the command line like this sudo gedit myFile.rb - this is not very sustainable! Thanks in advance!

  • Configuring permissions with Bastille

    - by Lucio
    I was using Bastille to improve the security of OS and I found the next question there I don't know if I should answer for YES or NOT: Questions: Would you like to set more restrictive permissions on the administration utilities? Explanation: In general, the default file permissions set by most vendors are fairly secure. To make them more secure, though, you can remove non-root user access to some administrator functions. If you choose this option, you'll be changing the permissions on some common system administration utilities so that they're not readable or executable by users other than root. These utilities (which include linuxconf, fsck, ipconfig, runlevel and portmap) are ones that most users could never have a need to access. This option will increase your system security, but there's a chance it will inconvenience your users. My users: When I installed Ubuntu I had create a user (admin), then I was able to create another user (people) but I cannot change the permissions of this user. Questions: The user there I am using like admin it's not the root, right? The effects of this option will affect to the two users (admin & people) or just to people?

  • SQL Server 2008 R2 Replication log reader could not execute sp_replcmds

    - by user49352
    This log reader agent worked perfectly for several months until the user referenced in the error was removed from the domain. After that time the error 'The process could not execute 'sp_replcmds' on 'SERVER'' was received with more detail 'Could not obtain information about Windows NT group/user' that referenced said user. This user was referenced nowhere in the the log reader agent other than the Publication Access List from which it was subsequenctly removed. The agent would still not successfully start up. The simple problem here, I believe, is that the log reader agent was created under that user and that no longer exists in the domain. Is there an 'owner' somewhere that needs to be changed? Every other function on the database continues to execute successfully. Any other help or thought would be appreciated.
