• How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

  - by Marco Mariani

  I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

• ft_stopword_file not picked up

  - by Alex Holsgrove

  I have a VPS server with a company called Webfusion. I want to remove some or all of the FULLTEXT stopwords because some specific words needs to be searchable with my DB content. I opened /etc/mysql/my.cnf and added the line ft_stopword_file="". I restarted the mysql service, ran a repair table and then tried my MATCH query with no success. I ran SHOW VARIABLES LIKE 'ft_%' and it simply shows (built-in) next to the stopword file. I am running WAMP on my workstation, and whilst I realise this isn't configured the same as a commercial VPS, the above method worked just fine. Couple someone please offer some guidance?

• How to telnet into facebook chat

  - by OSX Jedi

  I was able to use facebook chat with an external application using the following information: First, find your Facebook username by going to http://www.facebook.com/your_user/. Next, Open iChat, then select iChat » Preferences and click on the Accounts tab. Click on the + (plus) sign to add a new account, with these settings: * Account Type is Jabber Account * Account name is [email protected], and enter your password * Click the drop-down arrow to reveal Server options. Enter chat.facebook.com as the server name. * Enter 5222 as the port and click Done. Click Done again, and you are good to go. From reading this, it seems that it might be possible to telnet into facebook chat. I tried, but wasn't able to. Is it possible? How?

• CRL checking problem windows 2003

  - by Tim Mahy

  Hi all, we have CRL that is valid for 24 hours and has a next update in 12 hours. The CRL is valid from 12:12 AM to 12:12 AM and from 12:12 PM to 12:12 PM. In the logs of the CRL hosting webserver we see that one of our servers not always fetches the CRL at night, in most cases the server that missed the CRL IIS servers 403.16 on 12:13 PM. Is our following theory good: when a windows server misses fetching the CRL on it's nextUpdate but the current CRL is still valid, the fetching is not retried? This leads to a situation that when the CRL expires there is no overlap and gives a little time of 403.16 situations in IIS since the CRL is not thrusted and so all certificates are marked als unsafe? greetings, Tim

• Trouble installing Ubuntu 12.04 from USB

  - by Kyle J

  I want to dual-boot Ubuntu Desktop 12.04 on my new ultrabook which has an Intel i7 3517U processor 6GB RAM Windows 7, 64-bit no CD/DVD drive I created my bootable USB stick using pendrivelinux.com with the "ubuntu-12.04.1-desktop-i386.iso". I am following these directions because they include nice screenshots; however, I do not get very far in the process. I am able to boot into the Live Desktop, and then I try to install onto my hard disk. Here are the series of actions that I take next: First, I see this ( http://i.imgur.com/vucYH ) window, and click 'continue' Then I get this ( http://imgur.com/2wESc ) window, and click 'continue' again This appears: and I get worried because it seems like there is no recognition that I have Windows installed. According to the directions I am following, I should see /dev/sda1 and /dev/sda2 partitions. In the drop-down menu at the bottom the only "Device for boot loader installation" is /dev/sdb and no information is shown. I am hesitant to click 'Install Now' for fear of what it might do to Windows. 4. I click 'Quit' and cancel the installation, but then about 5 seconds later this ( http://imgur.com/a/yXi0C ) window pops up (I have expanded it to full screen to scroll and show all the details). 5. Another second later this ( http://imgur.com/vxcrN ) comes up. I'm not sure how relevant this is. Does anyone have any insight into this issue?? Why does it not show my current Windows partition? What would happen if I tried to continue with the installation process? Thanks! PS - sorry, it would only let me post 2 hyperlinks as a new user

• How to choose size for a cloud server (rackspace)

  - by Emil

  We're going to test the rackspace cloud next week to see how it's working with our web app. It's a LAMP environment with a lot of MySQL databases. How do I choose the "right" server size? On Rackspace I can choose slices with the memory of 256, 512, 1024, 2048, 4096 etc. Right now we don't have a lot of traffic (approx. 1000 visitors/day) but I thought the whole "cloud" idea was to not be limited and auto scale. Update: What I'm looking for is now a specification of what I need. I know it's too complex. I'm looking for examples, case studies etc. It would be interesting to hear something like "Yes we're serving 10 000 daily requests without spikes on a LAMP stack with only one slice on with 2 GB RAM".

• ubuntu: mumble 1.2.2 in Karmic

  - by Dan

  Karmic only has mumble 1.1.8, but if I want to connect to a 1.2 server I need to upgrade... So I would like to know how I can upgrade to mumble 1.2.2 without messing myself up for later when I upgrade to 10.04 and beyond... I just want a smooth transition into the next versions of mumble. Is there anyway to upgrade to this newer version and either keep it in the package manager or make it not interfere with the natural upgrades the program will later recieve from the package manager? Thanks, Dan

• Connection two wireless ADSL routers to share IPs

  - by user35218

  I have two wireless ADSL routers sitting right next to each other, each with his own internet connection. I'd like to be able to connect to a computer that is connected to router A from a computer that is connected to router B, while keeping both routers internet connection individually. i.e. If computer A is connected to router A, it will use router A internet connection, and a second computer, call it B, will be connected to router B, and will use router B internet connection. Is this possible?

• A few unpleasant facts about Visual Studio 2012.

  - by Ilya Verbitskiy

  I have been playing with Visual Studio 2012 for the last couple of days. New IDE is pretty good, but, unfortunately, I found a few unpleasant facts. First of all, new release is coming without Visual Studio setup projects. I am disappointed, because I am using it for my pet project – Easy Shutdown. The tool is a small widget-like application which allows you to reboot, log out or shut down you PC. I have not done any decision yet, but I would probably migrate to WiX. The second surprise is Microsoft will not add Visual Studio macros to the next release. Since I am lazy guy, I like small hacks using macros. For example I have macros to refresh all projects or attach to IIS.  The only way how to solve the problem is to convert your macros to Visual Studio plugin. I have not tried it yet, but I will definitely do in the nearest future. The third fact, I do not like, is Visual Studio default themes. May be somebody like it, but they are hard to adopt after Visual Studio 2010. Fortunately there is a solution. Matthew Johnson released Visual Studio 2012 Color Theme Editor. It comes with a few predefined themes. I really like the Blue one.

• Transfer files using ssh

  - by zozo

  Good day to all. I am using ssh (winSCP) to transfer some files from a server to my workstation. The problem is that at some files I get disconnected. Always same files. I am the owner of the directory so I guess the file permissions is not a problem. (Also I set the permissions to 777). Is there a size limit or something like that? Thank you for your time. Protocol is SFTP, server is 32bit machine. Files are 100MB tops. Added: Worked with filezilla using ftp. This temporarily fix the problem but is not exactly a solution since maybe next time I won't have root access to create a ftp account

• How to Manage Technical Employees

  - by Ajarn Mark Caldwell

  In my current position as Software Engineering Manager I have been through a lot of ups and downs with staffing, ranging from laying-off everyone who was on my team as we went through the great economic downturn in 2007-2008, to numerous rounds of interviewing and hiring contractors, full-time employees, and converting some contractors to employee status.  I have not yet blogged much about my experiences, but I plan to do that more in the next few months.  But before I do that, let me point you to a great article that somebody else wrote on The Unspoken Truth About Managing Geeks that really hits the target.  If you are a non-technical person who manages technical employees, you definitely have to read that article.  And if you are a technical person who has been promoted into management, this article can really help you do your job and communicate up the line of command about your team.  When you move into management with all the new and different demands put on you, it is easy to forget how things work in the tech subculture, and to lose touch with your team.  This article will help you remember what’s going on behind the scenes and perhaps explain why people who used to get along great no longer are, or why things seem to have changed since your promotion. I have to give credit to Andy Leonard (blog | twitter) for helping me find that article.  I have been reading his series of ramble-rants on managing tech teams, and the above article is linked in the first rant in the series, entitled Goodwill, Negative and Positive.  I have read a handful of his entries in this series and so far I pretty much agree with everything he has said, so of course I would encourage you to read through that series, too.

• How to execute files on LAN drives in a Windows Domain

  - by matnagel

  We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

• Assign PowerShell script to run at startup using PowerShell on Window Server 2012

  - by James Toyer

  I'm trying to write a PowerShell script that will run when a Windows 2012 instance is created on AWS using the configuration tools provided by AWS. My problem is that I want to change the name of the machine once it has started up, restart the machine and carry on set up process after. The main reason for this is that one of the applications, Boundary, installed in the set up process takes the name of the server when first installed. It is then doesn't seem possible to change it's name in their portal. Ideally I would have two PowerShell scripts, one to start the set up process, initialised through AWS and another that runs the first time the machine restarts. This second script would ideally be queued to run on the next start by the initial set up script. So I guess my question are: Is this possible? How would I go about doing this. My Google foo is letting me down here so any answers would be appreciated.

• How to get the Three.js import/export scripts into Blender on Ubuntu?

  - by Bane

  I have been working with 3D primitives in Three.js, but now I want to import some models. I plan on using Blender, which I have just downloaded with: sudo apt-get install blender However, I was instructed to put the import/export scripts in the .blender/2.62/scripts/addons folder, but it does not exist! .blender/2.62 does exist, but it only has a config folder. The next thing I did is manually changed the script search path in Blender's preferences from // to my homefolder/scripts, which contained the required io_mesh_threejs folder (which, in turn had the .py scripts inside). I saved the changes, restarted Blender, but still nothing: in the menu there is no mention of Three.js at all! What do I do? It would be great if I knew the installation path for Blender, because maybe I could put those scripts there manually. Where should it be installed? EDIT: these are the scripts I'm talking about, along with the instructions: https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender.

• Unity Greeter login screen cuts off login options

  - by ammianus

  I have a pretty newly installed Ubuntu 12.04, using Unity. My external monitor is 1920x1080 max resolution. In the Unity desktop itself everything looks great. I have an NVidia graphics card. When I start my computer and get to the Unity greeter login screen the display is oddly formatted and the resolution seems off. It looks like a zoomed view on the larger 1920x1080 screen. As such it crops the login options off to the left hand side of the screen. So I can only just see the edge of the password box for the user I want to log in with. I can log in with one account by default by blindly typing the password, but I am unable to switch to other accounts. Is there anything I can do to fix the log in screen display so that I can see the normal login options? Note: I first noticed it when I changed my desktop background and the next time I logged in I saw the issue.

• In Scrum, should you split up the backlog in a functional backlog and a technical backlog or not?

  - by Patrick

  In our Scrum teams we use a backlog, which mostly contains functional topics, but also sometimes contains technical topics. The advantage of having 1 backlog is that it becomes easy to choose the topics for the next sprint, but I have some questions: First, to me it seems more logical to have a separate technical backlog, where developers themselves can add pure technical items, like: we could improve performance in this method, this class lacks some technical documentation, ... By having one backlog, all developers always have to pass via the product owner to have their topics added to the backlog, which seems additional, unnecessary work for the product owner. Second, if you have a product owner that only focuses on the pure-functional items, the pure-technical items (like missing technical documentation, code that erodes and should be refactored, classes that always give problems during debugging because they don't have a stable foundation and should be refactored, ...) always end up at the end of the list because "they don't serve the customer directly". By having a separate technical backlog, and time reserved in every sprint for these pure technical items, we can improve the applications functionally, but also keep them healthy inside. What is the best approach? One backlog or two?

• Making WIF local STS to work with your ASP.NET application

  - by DigiMortal

  Making Windows Identity Foundation (WIF) STS test application work with your solution is not as straightforward process as you can read from books and articles. There are some tricks and some configuration modifications you must do to get things work. Fortunately these steps are simple one. 1. Move your application to IIS or IIS Express If your application uses development web server that ships with Visual Studio then make your application use IIS or IIS Express. You get simple support for IIS Express to Visual Studio 2010 after installing Visual Studio 2010 SP1. You can read more from my blog posting Visual Studio 2010 SP1 Beta supports IIS Express. NB! You don’t have to move your dummy STS project to IIS. 2. Change request validation mode to ASP.NET 2.0 As a next thing you will get the following error when coming back from dummy STS service: HttpRequestValidationException (0x80004005): A potentially dangerous Request.Form value was detected from the client. Open web.config of your application and add the following line before </system.web>: <httpRuntime requestValidationMode="2.0" /> Now you are done with configuring web application to work with STS.

• (Vista) Discover what app is reserving a shortcut key?

  - by Eddie Parker

  My problem is this: I've always managed to map WIN+V to foobar2000's "Next song" keyboard shortcut. For some reason, on this new machine, I can't. I've done this before on Vista, so the only thing I can think of is that some other application is holding onto this shortcut key. When I try to assign the shortcut key in foobar2000, nothing registers. When I press it outside of foobar2000, nothing occurs either. I'm at a loss as to how to proceed. Are there any apps to see what hooks are being requested by what application? Or is there a better way of diagnosing this?

• Message Driven Bean JMS integration

  - by Anthony Shorten

  In Oracle Utilities Application Framework V4.1 and above the product introduced the concept of real time JMS integration within the Framework for interfacing. Customer familiar with older versions of the Framework will recall that we used a component called the Multi-purpose Listener (MPL) which was a very light service bus for calling interface channels (including JMS). The MPL is not supplied with all products and customers prefer to use Oracle SOA Suite and native methods rather then MPL. In Oracle Utilities Application Framework V4.1 (and for Oracle Utilities Application Framework V2.2 via Patches 9454971, 9256359, 9672027 and 9838219) we introduced real time JMS integration natively for outbound JMS integration and using Message Driven Beans (MDB) for incoming integration. The outbound integration has not changed a lot between releases where you create an Outbound Message Type to indicate the record types to send out, create a JMS sender (though now you use the Real Time Sender) and then create an External System definition to complete the configuration. When an outbound message appears in the table of the type and external system configured (via a business event such as an algorithm or plug-in script) the Oracle Utilities Application Framework will place the message on the configured Queue linked to the JMS Sender. The inbound integration has changed. In the past you created XAI Receivers and specified configuration about what types of transactions to process. This is now all configuration file driven. The configuration files for the Business Application Server (ejb-jar.xml and weblogic-ejb-jar.xml) define Message Driven Beans and the queues to monitor. When a message appears on the queue, the MDB processes it through our web services interface. Configuration of the MDB can be native (via editing the configuration files) or through the new user exit capabilities (which is aimed at maintaining custom configuration across upgrades). The latter is better as you build fragments of configuration to make it easier to maintain. In the next few weeks a number of new whitepaper will be released to illustrate the features of the Oracle WebLogic JMS and Oracle SOA Suite integration capabilities.

• Transform coordinates from 3d to 2d without matrix or built in methods

  - by Thomas

  Not to long ago i started to create a small 3D engine in javascript to combine this with an html5 canvas. One of the issues I run into is how can you transform 3d to 2d coords. Since I cannot use matrices or built in transformation methods I need another way. I've tried implementing the next explanation + pseudo code: http://freespace.virgin.net/hugo.elias/routines/3d_to_2d.htm Unfortunately no luck there. I've replace all the input variables with data from my own camera and object classes. I have the following data: An object with a rotation, position vector and an array of 4 3d coords (its just a plane) a camera with a position and rotation vector the viewport - a square 600 x 600 surface. The example uses a zoom factor which I've set as 1 Most hits on google use either matrix calculations or don't implement camera rotation. Basic transformation should be like this: screen.x = x / z * zoom screen.y = y / z * zoom Can anyone point me in the right direction or explain to me howto achieve this? edit: Thanks for all your posts, I haven't been able to apply all this to my project yet but I hope to do this soon.

• 2D Collision masks for handling slopes

  - by JiminyCricket

  I've been looking at the example at: http://create.msdn.com/en-US/education/catalog/tutorial/collision_2d_perpixel and am trying to figure out how to adjust the sprite once a collision has been detected. As David suggested at XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision, I made a few sensor points (feet, sides, bottom center, etc.) and can easily detect when these points actually collide with non-transparent portions of a second texture (simple slope). I'm having trouble with the algorithm of how I would actually adjust the sprite position based on a collision. Say I detect a collision with the slope at the sprite's right foot. How can I scan the slope texture data to find the Y position to place the sprite's foot so it is no longer inside the slope? The way it is stored as a 1D array in the example is a bit confusing, should I try to store the data as a 2D array instead? For test purposes, I'm thinking of just using the slope texture alpha itself as a primitive and easy collision mask (no grass bits or anything besides a simple non-linear slope). Then, as in the example, I find the coordinates of any collisions between the slope texture and the sprite's sensors and mark these special sensor collisions as having occurred. Finally, in the case of moving up a slope, I would scan for the first transparent pixel above (in the texture's Ys at that X) the right foot collision point and set that as the new height of the sprite. I'm a little unclear also on when I should make these adjustments. Collisions are checked on every game.update() so would I quickly change the position of the sprite before the next update is called? I also noticed several people mention that it's best to separate collision checks horizontally and vertically, why is that exactly? Open to any suggestions if this is an inefficient or inaccurate way of handling this. I wish MSDN had provided an example of something like this, I didn't know it would be so much more complex than NES Mario style pure box platforming!
