• HTTP events? Is there a standard / precedent for this?

  - by user619818

  Our architecture is HTTP servers (custom written) which whereby custom clients send a HTTP request for some information and information is returned just as HTTP works. But we need a special custom 'extension' which is a request which is a subscription for receiving asynchronous 'events' on a resource. For example the client sends an http request subscribing for events on some entity. As the 'entity' generates events they are passed to the http server and the http server must then lookup subscriptions for that entity and send the event message to all subscribed clients. Hope that makes sense. So my questions are: Has this been done before / or is there a standard I should be looking at? If no standard, any suggestions on how to implement? How does a http server send an unsolicited 'message' to a client?

• Bring the Windows 8 'Start Menu' back!

  - by ihaynes

  I've been using the the Windows 8 RTM from MSDN for a week but the more of my normal software I load onto the machine the more awkward it becomes using the new 'Metro' (yes I know that name is now not used) 'Start' screen. Yes, you can oraganise your programs in groups, or you can add them to the Quick Launch bar, or you can create alphabetic folders on the desktop but sorry Microsoft, none of these are as logical as the alphabetic Start menu of previous Windows versions.Fortunately the good people at Stardock have a solution in 'Start8', which brings the Start Menu we know and love back to Windows 8. It's still in Beta and the current one runs out in October. I'm looking forward to the final release and like lots of other users, I'll be happy to pay for this.Lets hope Microsoft either reinstate the Start Menu in the first service pack or gives us a usable alternative. In the meantime, here's an excellent solution.http://www.stardock.com/products/start8/

• Looking for full web based booking system

  - by Sandro Dzneladze

  I've searched around here but could not find any booking system that would suit my need. I hope maybe you can help me out. I've already seen question #11379 over here. Solutions provided there are not helping and scripts not interesting. I'm looking for a booking system that support infinite number of hotels/rooms/pricingschemes. There should be unlimited number of hotel owner/users, who can access control panel and set availability for their hotel. Or create seasonal prices and adjust them. I should be able to have 15% booking fee paid through credit cart. I can work on integration with my system, it just needs to have correct APi/functionality to support this. I love wordpress so if there are some nice plugins for that, I'm open for suggestions. But this is not a must. It should be php/mysql based as I'm not good at anything else :)

• How was collision detection handled in The Legend of Zelda: A Link to the Past?

  - by Restart

  I would like to know how the collision detection was done in The Legend of Zelda: A Link To The Past. The game is 16x16 tile based, so how did they do the tiles where only a quarter or half of the tile is occupied? Did they use a smaller grid for collision detection like 8x8 tiles, so four of them make one 16x16 tile of the texture grid? But then, they also have true half tiles which are diagonally cut and the corners of the tiles seem to be round or something. If Link walks into tiles corner he can keep on walking and automatically moves around it's corner. How is that done? I hope someone can help me out here.

How do I get the "normal (graphical)" Ubuntu back? I hope you know what I mean. Since English is not my first language I can't explain this the way I would like to. Mark

• Procedural Planets, Heightmaps and Textures

  - by henryprescott

  I am currently working on an OpenGL procedural planet generator. I hope to use it for a space RPG, that will not allow players to go down to the surface of a planet so I have ignored anything ROAM related. At the moment I am drawing a cube with VBOs and mapping onto a sphere. I am familiar with most fractal heightmap generating techniques and have already implemented my own version of midpoint displacement (not that useful in this case I know). My question is, what is the best way to procedurally generate the heightmap. I have looked at libnoise which allows me to make tilable heightmaps/textures, but as far as I can see I would need to generate a net like this. Leaving the tiling obvious. Could anyone advise me on the best route to take? Any input would be much appreciated.

• HP mini 5102 Ethernet does not work after suspend on Lubuntu 12.10

  - by Marcin

  Ethernet works fine after system is rebooted The onboard card is seen in 'lspci' as: 43:00.0 Ethernet controller: Marvell Technology Group Ltd. Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] (rev 11) After system being suspended the sky2 driver loads but does not enable the NIC. I have noticed that it happens when PC is left suspended for longer period of time (few houres) Trying to reproduce it I have tried to load the sky2 driver with 'modprobe sky2'. Unfortunately typing 'ifconfig -a' for the onboard ethernet adapter does not list the driver once the sky2 driver is loaded. I have searched internet and I found some information about a bug in kernel. Hovewer it was reported in 2010 so I hope it has been fixed. Here it is http://lists.opensuse.org/opensuse-bugs/2010-02/msg01473.html

• You know you're a "version control avoider" if [closed]

  - by kmote

  I'm in the process of trying to introduce Version/Revision Control to a team of developers who have never used it. I'll be giving a presentation that I hope will be a persuasive explanation of the importance of Version Control -- the benefits of using it and the liabilities of avoiding it. I'd like to kick it off with an amusing but instructive list modelled after the "redneck" line of jokes. Can anyone help me add to this list? "You know you're a Version Control Avoider if..." You have a bunch of files or folders with names like Engine_05212012_works_old[2].cpp You've had to explain to your boss how you accidentally overwrote production code. I don't consider myself terribly witty, but I think a little humor could be helpful in this situation. Any ideas for how to extend this list? [Bonus points if you can suggest a better moniker than "Version Control Avoider"]

• KCDC 2011

  - by NoReasoning

  Well, Saturday was my presentation on Programming with Windows Azure, and it went well. Everything worked as I had wanted and I got to everything that I had planned. I did not even need my emergency backup filler. I only hope that the folks who attended got something from it. As for the whole conference, I think it was a resounding success. There were a LOT of good sessions to attend and people to meet. I had a great time, and I look forward to next year with great anticipation. Kudos to all (Lee, Jonathan, Boon(?)) and all (Jasmine, Nathan) who put this on. Great job, everyone!

• Windows: starting sqlplus in new window from cygwin bash

  - by katsumii

  When I start sqlplus, more often than not, I want it to start in new window,whether it be on Linux/Solaris GNOME or Windows.I seldom use GNOME so I never bothered to figure out how.On Windows, one can use Windows menu or Win+R "Run" dialog but I prefer usingbash. Because, this way, I can keep the history in ~/.bash_history file.There are 2 ways. Using cmd.exe or cygstart.For example, to start default sqlplus.exe to connect to default local instance. $ cmd /c "start sqlplus sys/oracle as sysdba" 2nd example. To start sqlplus in 2nd Oracle home and to connect to non-default local instance. $ ORACLE_SID=orcl cygstart /cygdrive/g/app/product/11.2.0.3/dbhome_1/BIN/sqlplus scott I hope this tip helps reducing your DBA time.

• Q&amp;A: How do I cancel my Windows Azure Platform Introductory Special? (or any Subscription)

  - by Eric Nelson

  Short answer: Don’t! Just kidding :-) Long answer: I believe it is the same process as for other Microsoft Online Services – but I have never tried it. Hence please post a comment if you follow this successfully or not and I will amend. From http://www.microsoft.com/online/help/en-us/mocp/, search for “cancel” and you get: What I am not clear about is whether an Introductory Special is classed as a trial. Either way, the answer is to contact support and ask to cancel. I would suggest you are fully armed with details of your subscription which you can get from signing in to https://mocp.microsoftonline.com. You can contact support via a online web form at https://mocp-support.custhelp.com/ Or You can call them. The details are again on the support page http://www.microsoft.com/online/help/en-us/mocp/  In the UK you can call 0800 731 8457 or (0) 20 3027 6039 Monday – Friday 09:00 – 17:00 GMT (UTC). I hope that helps.

• Is there animation software available for Ubuntu?

  - by Robert Low

  Is there commercial-grade computer animation software available for Ubuntu, similar to the professional software sold for the Windows operating system? This question goes out to those of you who may be using such software professionally. My daughter recently graduated from the Art Institute of Seattle, and needs to put together an animation portfolio in order to interest employers in the field. As you know, such software is usually provided by the employer and the costs are high - several thousand dollars. I suggested that she investigate Ubuntu as a possible way to acquire the tools she needs. But, since I have no idea what might be available, either as open source or proprietary animation software, I am reaching out to the Ubuntu community for help in the hope someone who is using such software can help her. Thank you for reading this post, and for any information you might have.

• Terminology For Web Development and General Programming/Software?

  - by Zenph

  EDIT: I should clarify. THe particular terms I listed below I fully understand. I also understand w3schools doesn't have the greatest information. These are just examples. I don't expect everybody to understand what an example is, but I hope the majority do. Does anybody have any resources listing terms related to programming and web development, or care to pitch in? Things like: Runtime Build time Framework Library Normalize I'm primarily a PHP developer so anything about that. I really am looking for general terms and specific terms related to web development, PHP, SQL, CSS, HTML. Appreciate any input. Couple I found: http://www.w3schools.com/site/site_glossary.asp http://docs.roxen.com/pike/7.0/tutorial/fundamentals/concepts.xml

• Need a remote desktop to a headless server without logging in first

  - by user17971

  I've been using Linux for many years now but only to run servers. Over the last few days I've been struggling with a technical / configuration issue which I hope someone can help with. I've installed / un-installed many packages but just can't figure out what the "right" way of doing this is. The requirement seems simple Server runs Ubuntu 10.04 with xubuntu and SSH (I do NOT want to connect any screen, keyboard or mouse to the server) I have Windows 7 machine with putty on it and logging in to the server using SSH is fine I want to run an xterminal session on my Windows machine. Amongst the things I've tried is VNU but I can't get it to work because I believe you have to login on the server first. Thanks in advance

• XNA: SpriteFont question

  - by Zukki

  Hi everyone, I need some help with the SpriteFont. I want a different font for my game, other than Kootenay. So, I edit the SpriteFont xml, i.e: <FontName>Kootenay</FontName> or <FontName>Arial</FontName> No problem with Windows fonts, or other XNA redistributable fonts pack. However, I want to use other fonts, that I downloaded and installed already, they are TTF or OTF, both supported by XNA. My problem is, I cant use them, I got this error: The font family "all the fonts i tried" could not be found. Please ensure the requested font is installed, and is a TrueType or OpenType font. So, checking at the windows fonts folder, I check the properties and details of the fonts, I try all the names they have, and but never works. Maybe I need some kind of importing or installing in order to use them, I dont know, and I hope you guys can help me, thanks!

• How You Helped Shape Java EE 7...

  - by reza_rahman

  For many of us working with the JCP for years, the commitment to transparency and openness is very clear. For others, perhaps the most visible sign to date of this high regard for grassroots level input is a survey on Java EE 7 gathered a few months ago. The survey was designed to get open feedback on a number of critical issues central to the Java EE 7 umbrella specification including what APIs to include in the standard. The survey was highly successful with a large number of high quality responses. With Java EE 7 under our belt and the horizons for Java EE 8 emerging, this is a good time to thank everyone that took the survey once again for their thoughts and let you know what the impact of your voice actually was. I've posted the details on my personal blog. I hope you are encouraged by how your input to the survey helped shape Java EE 7 and continues to shape Java EE 8. Maybe now is the time for you to get more involved :-)?

• Nagios3 crashes with SIGSEGV

I found this in the log file: Nagios 3.2.0 starting... (PID=11729) Local time is Wed Dec 22 14:15:31 2010 Caught SIGSEGV, shutting down... I tried to remove and re-install it without success. After googling, it seems that no one has a solution for this. I don't want to install it from source unless it is really the last hope.

• Software consultancy or in-house developement?

  - by JefClaes

  What are the benefits and drawbacks of working as an in-house developer versus working as a consultant and vice versa? I am pretty sure both breeds can be found on these forums and I hope you are willing to share your experience. Edit: Let me clarify the question. I wonder how the experience is like being a developer. For example: Being an in-house developer, you are able to learn from your mistakes. Being a consultant is often more challenging, because there is more variety in the problems you have to solve. PS: Although I realise that this is a subjective question, I don't necessarily see it as one of those bad-subjective questions.

• How to change Port 27000 from filtered to open status

  - by Nadarajah Ranjan

  In my ubuntu box I am running flexlm licensing software on port 27000 and I am able to pull the license from the this port to run the simulation software locally. I am also trying to run the same software in another Linux machine (opensuse) by using the flexlm license from the Ubuntu box. However, my opensuse box is unable to communicate with port 27000 in my Ubuntu box. I have turned off the firewall on the Ubuntu box, played around with iptables and when I do a nmap from my opensuse box to Ubuntu box the message I get is that port 27000 is on filtered status. My understanding is that filtered status does not allow the opensuse box to communicate with Ubuntu. My question is how to change port 27000 from filtered status to open status? Hope someone can help me out. Thank you.
