• Ubuntu Server 12.04 as a router. Problem with DNS

  - by Lorenzo

  I have a virtualbox lab made up of 4 Windows 2008 R2 servers (DC/DNS,SQL,SHAREPOINT, EXCHANGE) that are configured with static ip addresses with NIC's attached to Internal network. Everything works. I had the requirement to execute some tests that also access external services available on the internet. To keep things clean and similar to the production environment I have installed another VM, with Ubuntu Server 12.04 64 bit and configured (I hope) to work as a router like described on this post. This VM has two network interfaces: first is Bridged with the host and is used as a WAN connection and the other one attached in the Internal Network with its own static IP address on the internal network subnet. But actually the Windows servers does not connect to the internet while the unix one connects. I did a route command. this is the result: Kernel IP Routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.69.121.1 0.0.0.0 UG 100 0 0 eth0 10.69.121.0 * 255.255.255.0 U 0 0 0 eth0 192.168.83.0 * 255.255.255.0 U 0 0 0 eth1 Can somebody help me with this configuration? :) Thanks! Addendum: I forgot to mention that one of the windows server hosts a DNS service for which I should maybe configure a forwarding server but I do not exactly know which server to forward on... :(

• I don't know C. And why should I learn it?

  - by Stephen

  My first programming language was PHP (gasp). After that I started working with JavaScript. I've recently done work in C#. I've never once looked at low or mid level languages like C. The general consensus in the programming-community-at-large is that "a programmer who hasn't learned something like C, frankly, just can't handle programming concepts like pointers, data types, passing values by reference, etc." I do not agree. I argue that: Because high level languages are easily accessible, more "non-programmers" dive in and make a mess In order to really get anything done in a high level language, one needs to understand the same similar concepts that most proponents of "learn-low-level-first" evangelize about. Some people need to know C; those people have jobs that require them to write low to mid-level code. I'm sure C is awesome, and I'm sure there are a few bad programmers who know C. Why the bias? As a good, honest, hungry programmer, if I had to learn C (for some unforeseen reason), I would learn C. Considering the multitude of languages out there, shouldn't good programmers focus on learning what advances us? Shouldn't we learn what interests us? Should we not utilize our finite time moving forward? Why do some programmers disagree with this? I believe that striving for excellence in what you do is the fundamental deterministic trait between good programmers and bad ones. Does anyone have any real world examples of how something written in a high level language—say Java, Pascal, PHP, or Javascript—truely benefitted from a prior knowledge of C? Examples would be most appreciated.

• Google Webmaster tools Incorrect rel-alternate-hreflang implementation warning message

  - by Noam

  I'm getting this warning msg. in Google webmaster tools Incorrect rel-alternate-hreflang implementation In particular, there seems to be a problem with missing or incorrect bi-directional linking (when page A links with hreflang to page B, there must be a link back from B to A as well). This msg. seems pretty straight forward, but when checking their example pages, I'm not finding anything wrong. I'm using alternate for translation of main site menu, titles, etc.. In each page I have this: <link rel="alternate" hreflang="en" href="http://mydomain.com/page" /> <link rel="alternate" hreflang="jp" href="http://ja.mydomain.com/page" /> <link rel="alternate" hreflang="ko" href="http://ko.mydomain.com/page" /> <link rel="alternate" hreflang="th" href="http://th.mydomain.com/page" /> <link rel="alternate" hreflang="es" href="http://es.mydomain.com/page" /> <link rel="alternate" hreflang="pt" href="http://pt.mydomain.com/page" /> I've double checked this exists in all the 6 pages. This is the first time I've seen this msg although I've implemented this at least 6 months ago, and implementation hasn't changed. Is there any way to check a specific set of pages for these things? Am I missing something in my implementation? We're auto-redirecting people from a location to their specific language, and give them an option to manually change this. I've also just found out about the suggestion for Vary HTTP header - is that relevant and important here?

• .NET Demon support for VS 11 dark theme

  - by Alex.Davies

  I'm pleased to announce that .NET Demon will be shipping simultaneously with Visual Studio 11, whenever it ends up being released. That means we're going to make sure that a version of .NET Demon is released very near to the Visual Studio 11 final release which supports the new version of VS fully. The interesting part of this support is going to be the new dark theme of VS, which I'm looking forward to using. I'm told dark colours reduce eye strain for developers. It's important that extensions like .NET Demon switch to a dark theme when the rest of the IDE changes, or the dark theme will look silly. Unfortunately, none of my favourite extensions look right in the dark theme yet, so even though I use Visual Studio 11 beta for my day-to-day development already, I can't use the dark theme. Luckily .NET Demon uses WPF throughout, and the team at Microsoft are helping us to use the WPF Style system to make it easy for me to implement the support without having to add colour attributes to all the controls manually. We should have dark theme support in .NET Demon in the next month or so.

• Implementing Light Volume Front Faces

  - by cubrman

  I recently read an article about light indexed deferred rendering from here: http://code.google.com/p/lightindexed-deferredrender/ It explains its ideas in a clear way, but there was one point that I failed to understand. It in fact is one of the most interesting ones, as it explains how to implement transparency with this approach: Typically when rendering light volumes in deferred rendering, only surfaces that intersect the light volume are marked and lit. This is generally accomplished by a “shadow volume like” technique of rendering back faces – incrementing stencil where depth is greater than – then rendering front faces and only accepting when depth is less than and stencil is not zero. By only rendering front faces where depth is less than, all future lookups by fragments in the forward rendering pass will get all possible lights that could hit the fragment. Can anyone explain how exactly you need to render only front faces? Another question is why do you need the front faces at all? Why can't we simply render all the lights and store the ones that overlap at this pixel in a texture? Does this approach serves as a cut-off plane to discard lights blocked by opaque geometry?

• OpenGL: Want to keep gun on top of car and be able to control angle. Having difficulties.

  - by Blair

  So I am making a simple game. I want to put a gun on top of a car so basically like a long rod in the middle of a black is how I am modelling it right now. I want to be able to control the angle of the gun. Basically it can go forward all the way so that it is parallel to the ground facing the direction the car is moving or it can point behind the car and any of the angles in between these positions. I have something like the following right now but its not really working. Is there an better way to do this that I am not seeing? #This will place the car glPushMatrix() glTranslatef(self.position.x,1.5,self.position.z) glRotated(self.rotation, 0.0, 1.0, 0.0) glScaled(0.5, 0.5, 0.5) glCallList(self.model.gl_list) glPopMatrix() #This will place the gun on top glPushMatrix() glTranslatef(self.position.x,2.5,self.position.z) glRotated(self.tube_angle, self.direction.z, 0.0, self.direction.x) print self.direction.z glRotated(45, self.position.z, 0.0, self.position.x) glScaled(1.0, 0.5, 1.0) glCallList(self.tube.gl_list) glPopMatrix() This almost works. It moves the gun up and down. But when the car moves around the angle of the gun changes. Not what I want.

• Requiring multithreading/concurrency for implementation of scripting language

  - by Ricky Stewart

  Here's the deal: I'm looking at designing my own scripting/interpreted language for fun. I'm only in the planning stages right now; I want to make sure I have a very strong hold on exactly how I will implement everything before I start coding. What I'm currently struggling with is concurrency. It seems to me like an easy way to avoid the unpredictable performance that comes with garbage collection would be to put the garbage collector in its own thread, and have it run concurrently with the interpreter itself. (To be clear, I don't plan to allow the scripts to be multithreaded themselves; I would simply put a garbage collector to work in a different thread than the interpreter.) This doesn't seem to be a common strategy for many popular scripting languages, probably for portability reasons; I would probably write the interpreter in the UNIX/POSIX threading framework initially and then port it to other platforms (Windows, etc.) if need be. Does anyone have any thoughts in this issue? Would whatever gains I receive by exploiting concurrency be nullified by the portability issues that will inevitably arise? (On that note, am I really correct in my assumption that I would experience great performance gains with a concurrent garbage collector?) Should I move forward with this strategy or step away from it?

• Observable Adapter

  - by Roman Schindlauer

  .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

• JavaOne 2012 Day 1

  - by Geertjan

  Day 1, Sunday, started the night before for those attending the NetBeans Party at Johnny Foley's: Invitations had been sent out prior to the party to all speakers for NetBeans Day, as well as speakers in JavaOne sessions where NetBeans is going to be used. That turns out to be around 40 people, who hung out until quite late, with snacks and drinks. Next day, NetBeans Day had most sessions with completely packed rooms, which means there were around 300 people! Panel discussions around central themes in the NetBeans ecosystem (Java EE, JavaFX, and NetBeans Platform) were held, which resulted in a whole bunch of people up on stage throughout the day, such as this group of speakers in the Java EE session: From left to right above you see Sean Comerford from ESPN.com, John Yeary the Java EE panel moderator and JUG lead from Greenville, Cagatay Civici the PrimeFaces lead developer, Glenn Holmer long time NetBeans enthusiast (more on him below) from the Weyco Group, and NetBeans/Java EE book author David Heffelfinger. There were panels just like the above for JavaFX and the NetBeans Platform too, with very interesting and dynamic talks, such as one by JavaFX book authors Gail and Paul Anderson, who showed off this brilliant JavaFX/NetBeans Platform mashup: NetBeans Day ended with a good discussion about how to get involved in the NetBeans community, wrapping up with an award ceremony with two very special NetBeans community awards: Then everyone caught buses to the Masonic Auditorium, where 4 hours of keynotes took place. This is what the room looked like: The 4 hours ended with a very well received HTML5/NetBeans demo, showing of NetBeans IDE 7.3 features, by NetBeans director John Ceccarelli. And I liked this slide during an earlier keynote session by Oracle VP Hasan Rizvi: There was really a lot of love for NetBeans during the JavaOne keynote sessions and I don't remember hearing any other IDE being mentioned, in any way at all. Next there was the Duke's Choice Award ceremony, outside the Hilton in a cool lounge area, where, among others, Timon and Angelo from the NetBeans Platform community received their awards for AgroSense and MICE. In between all of the above, I met very many friends from previous conferences, as well as several new ones. It was clearly a great start to the conference. Looking forward to what the rest of the week will bring!

• Reflecting on 2010 and Looking into 2011

  - by Sam Abraham

  In early 2010, I had blogged and shared my excitement as I was about to embark on a new journey relocating to South Florida.     As I settled down and adjusted to my new life, I was presented with an opportunity to get actively involved and volunteer in the local Florida .Net and Project Management communities.  I have since devoted a significant portion of my time to community initiatives, coordinating the West Palm Beach .Net User Group, volunteering as a member of the INETA Speaker’s Bureau and traveling to attend/speak at .Net code camps and user groups throughout the states of Florida and New York. I have also taken on various volunteer roles at the South Florida Chapter of the Project Management Institute starting as core team member on the chapter’s mentoring initiative and ending the year as Project Manager of the chapter’s mentoring program and as Director of Electronic Communications on the chapter’s IT team. I am also serving a one year term (2010-2011) as secretary and founding board member of Florida’s first official chapter of the International Association for Software Architects (IASA).   A big thank you is due for those who afforded me the opportunity and privilege to take part of these initiatives and those who provided guidance and encouragement when I needed them the most.   Looking ahead into 2011, I hope to continue my community involvement and volunteer activities. I will start by dedicating the first 5 weekends in the New Year to teach a free comprehensive Microsoft PowerPoint class at church. My goal will be to start from scratch and slowly cover the various available PowerPoint features that can be leveraged to create captivating presentations. Starting February, I will be resuming my user group/code camp speaking engagements at our South Florida .Net Code Camp and the West Palm Beach .Net User Group.   I look forward to continuing to meet, chat and share with our technical community members and to another active year in community service.   All the best, --Sam Abraham

• Stuck at enemy movement

  - by Syed

  I am making a TD game in unity, Initially I made all of my enemy movements frame rate dependent say: I had a grid point1 at -22.65 and other at -21.1, diagrammatically: (-22.65) _________(-21.1)_______(-21.1+1.55) ...... so the distance on x axis between two points is 1.55, divided it by 25 jumps with each enemy jump of 0.062 of each frame. On reaching on next point of grid the enemy find again its path. All went fine until I have requirement of FastForward and Pause feature. I used timeScale property of unity but it wont work as they are frame dependent. I also tried double speed of enemy on clicking fast forward button at any time, it has some issues that enemy jumps are now less and it fails to reach on next grid point. Could someone suggest me solution to my problem. Do I need to change the enemy movement code to make it frame independent ?? I need the enemy to reach on the grid specific point I also need later to slow down any one enemy's speed when tower fires on it. Thnx

• Prevent mail flagged as spam when switching mail servers (new SPF records)?

  - by Jakobud

  For our business, we send out a significant amount of newsletter alerts to customers that sign up for it on our website. We used to send this mail directly from our web server via PHP. But because the web server limited us to the number of emails we could send per day, we purchased a VM server at a different host (that doesn't throttle email) and we are going to use that account solely for sending out the emails. Anyways, now that the SPF records are going to be different from what they used to be and the source mail server is different, what steps need to be taken to prevent these emails being flagged as spam? I know in Gmail, it's pretty smart about determining if the person actually sending the email is sending it from the server it expects (for flagging Phishing emails, etc). We don't want that to happen to our emails. Just sending a couple test emails out, Gmail's shows the SPF record saying: Authentication-Results: mx.google.com; spf=neutral (google.com: XXX.XXX.23.176 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected] So is there anything we need to do with regards to SPF records as we move forward?

• Small-scale database options for .NET

  - by raney

  I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

• Authentication system brainstorm

  - by gansbrest

  Hi. We got multiple small websites (microsites) and one main high traffic one with big users base. Right now the requirement is to build authentication system which should allow users to loign with the same identity across the network. All website are running on different domains, powered by Drupal 6 CMS and have separate databases (so sharing tables with prefix is not an option + it creates a huge mess in the db). Here is the set of core requirements I came up with: Users should be able to login with the same credentials to all sites within the network User’s data sharing between Main site (storage) and all micro sites within the network Data synchronization across the network when user changes the data (update email or password for example) The login/registration process should be seamless and consistent Register on any of the sites across the network and use that identity to login later on. In the future there might be a need to add openid authentication options. Basically we are looking at something similar stackexchange does, but not sure if they have central users base on not. I was thinking about custom solution which will include 2 parts (modules), one will be stored on the Main site for users data storing and responding to requests from clients. Second part (module) will be placed on each microsite, which is going to send requests to the Master. Some kind of client - server setup. One of the complications I see right away is #3. Data Synhcronization across the network. I just don't want to reinvent the wheel and maybe some work is already done in this direction. Looking forward to your ideas on how to approach this project. EDIT: We use MySQL database

• Can windows XP be better than any Ubuntu (and Linux) distro for an old PC?

  - by Robert Vila

  The old laptop is a Toshiba 1800-100: CPU: Intel Celeron 800h Ram 128 MB (works ok) HDD: 15GB (works ok) Graphics adapter: Integrated 64-bit AGP graphics accelerator, BitBIT, 3D graphic acceleration, 8 MB Video RAM Only WindowsXP is installed, and works ok: it can be used, but it is slow (and hateful). I thought that I could improve performance (and its look) easily, since it is an old PC (drivers and everything known for years...) by installing a light Linux distro. So, I decided to install a light or customized Ubuntu distro, or Ubuntu/Debian derivative, but haven't been successful with any; not even booting LiveCDs: not even AntiX, not even Puppy. Lubuntu wiki says that it won't work because the last to releases need more ram (and some blogs say much more cpu -even core duo for new Lubuntu!-), let alone Xubuntu. The problems I have faced are: 1.There are thousands of pages talking about the same 10/15 lightweight distros, and saying more or less the same things, but NONE talks about a simple thing as to how should the RAM/swap-partition proportion be for this kind of installations. NONE! 2.Loading the LiveCD I have tried several different boot options (don't understand much about this and there's ALWAYS a line of explanation missing) and never receive error messages. Booting just stops at different stages but often seems to stop just when the X server is going to start. I am able to boot to command line. 3.I ignore whether the problem is ram size or a problem with the graphics driver (which surprises me because it is a well known brand and line of computers). So I don't know if doing a partition with a swap partition would help booting the LiveCD. 4.I would like to try the graphical interface with the LiveCD before installing. If doing the swap partition for this purpose would help. How can I do the partition? I tried to use Boot Rescue CD, but it advises me against continuing forward. I would appreciate any ideas as regards these questions. Thank you

• Domain forwarding to a IE "trusted site" opens a blank page

  - by Michael Jasper

  My employer, a University, regularly hosts conferences and other events. While websites for these sites are hosted on our domain, they frequently request customized .com urls. We then forward these domains to the specific site. Recently, we discovered a problem, where a page will not load if the following conditions are met(using a current example): website is created on our CMS for a conference http://continue.weber.edu/nulc a domain is created http://www.nulc2012.com and forwarded to http://continue.weber.edu/nulc The user enters http://www.nulc2012.com into their address bar using IE7 or IE8 The user has *.weber.edu listed as a "trusted site" in IE security settings (the case for nearly all on-campus computers) When this happens, their browser will correctly transfer to the page http://continue.weber.edu/nulc/index.php, however the page is blank, returning only: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD> <BODY></BODY></HTML> Is there any know solution to this problem? Or am I missing something completely? Note: Tested websites do load correctly in Chrome, Firefox, and Safari

• How to determine where on a path my object will be at a given point in time?

  - by Dave

  I have map and an obj that is meant to move from start to end in X amount of time. The movements are all straight lines, as curves are beyond my ability at the moment. So I am trying to get the object to move from these points, but along the way there are way points which keep it on a given path. The speed of the object is determined by how long it will take to get from start to end (based on X). This is what i have so far: //get_now() returns seconds since epoch var timepassed = get_now() - myObj[id].start; //seconds since epoch for departure var timeleft = myObj[id].end - get_now(); //seconds since epoch for arrival var journey_time = 60; //this means 60 minutes total journey time var array = [[650,250]]; //way points along the straight paths if(step == 0 || step =< array.length){ var destinationx = array[step][0]; var destinationy = array[step][1]; }else if( step == array.length){ var destinationx = 250; var destinationy = 100; } else { var destinationx = myObj[id].startx; var destinationy = myObj[id].starty; } step++; When the user logs in at any given time, the object needs to be drawn in the correct place of the path, almost as if its been travelling along the path whilst the user has not been at the PC with the available information i have above. How do I do this? Note: The camera angle in the game is a birds eye view so its a straight forward X:Y rather than isometric angles.

• SQL Saturday Atlanta: Intro To Performance Tuning

  - by Mike Femenella

  I'm looking forward to speaking in Atlanta on the 24th, will be fun to get back down that way to visit with some friends and present two topics that I really enjoy. First, an introduction to performance tuning. Performance tuning is a very wide and deep topic and we're staying close to the surface. I direct this class for newbie sql users who have less than 2 years of experience. It's all the things I wish someone would have told me in my first 2 years about what to look for when the database was slow...or allegedly slow I should say. We'll cover using profiler to find slow performing queries and how to save the data off to a table as well as a tour of other features. The difference between clustered, non clustered and covering indexes. How to look at and understand an execution plan (at a high level) and finally the difference between a temp table and a table variable and what the implications are of using either one in your code. That pretty much takes up a full hour. Second presentation, Loading Data in Real Time. It's really a presentation about partitioning but with a twist that we used at work recently to solve a need to load some data quickly and put it into production with minimal downtime. We'll cover partition functions, schemes,$partition, merge, sys.partitions and show some examples of building a set of partitioned tables and using the switch statement to move it from one table to another. Finally we'll cover the differences in partitioning between 2005 and 2008. Hope to see you there! And if you read my blog please introduce yourself!

• Two JavaFX Community Rock Stars Join Oracle

  - by Tori Wieldt

  from Sharat Chander, Director - Java Technology Outreach: These past 24+ months have proved momentous for Oracle's stewardship of Java.  A little over 2 years ago when Oracle completed its acquisition of Sun, a lot of community speculation arose regarding Oracle's Java commitment.  Whether the fears and concerns were legitimate or not, the only way to emphatically demonstrate Oracle's seriousness with moving Java forward was through positive action.  In 2010, Oracle committed to putting Java back on schedule whereby large gaps between release trains would be a thing of the past.  And in 2011, that promise came true.  With the 2011 summer release of JDK 7, the Java ecosystem now had a version brought up to date.  And then in the fall of 2011, JavaFX 2.0 righted the JavaFX ship making rich internet applications a reality. Similar progress between Oracle and the Java community continues to blossom.  New-found relationship investments between Oracle and Java User Groups are taking root.  Greater participation and content execution by the Java community in JavaOne is steadily increasing.  The road ahead is lit with bright lights and opportunities. And now there's more good news to share.  As of April 2nd, two recognized JavaFX technology luminaries and "rock stars" speakers from the Java community are joining Oracle on a new journey. We're proud to have both Jim Weaver and Stephen Chin joining Oracle's Java Evangelist Team.  You'll start to see them involved in many community facing activities where their JavaFX expertise and passion will shine.  Stay tuned! Welcome @JavaFXpert and @SteveonJava !
