• What is Java used for these days?

  - by Barry Brown

  Java is fifteen years old. It started life as an alternative to C++ with a comprehensive standard library. Riding on the coattails of the Internet boom, it was popular for writing web applets. Its supposed portability was touted as a way to write desktop apps that would run on any platform. Now it's 2010. Applets are long gone. Desktop apps are giving way to web and mobile apps. Scripting languages are very popular, as is Flash, especially among web-centric developers. People have been chanting "Java's death is near" for several years. Yet a quick job search shows that Java is still a desired skill among programmers. So what is Java used for these days? What kinds of apps are you writing in Java? This should give us an idea of the "state of Java" today. Has the Java tide shifted from Swing desktop apps to Android mobile apps? If you write programs in a JVM language (such as Scala or Groovy), mention it.

• How to use Pixel Bender (pbj) in ActionScript3 on large Vectors to make fast calculations?

  - by Arthur Wulf White

  Remember my old question: 2d game view camera zoom, rotation & offset using 'Filter' / 'Shader' processing? I figured I could use a Pixel Bender Shader to do the computation for any large group of elements in a game to save on processing time. At least it's a theory worth checking. I also read this question: Pass large array to pixel shader Which I'm guessing is about accomplishing the same thing in a different language. I read this tutorial: http://unitzeroone.com/blog/2009/03/18/flash-10-massive-amounts-of-3d-particles-with-alchemy-source-included/ I am attempting to do some tests. Here is some of the code: private const SIZE : int = Math.pow(10, 5); private var testVectorNum : Vector.<Number>; private function testShader():void { shader.data.ab.value = [1.0, 8.0]; shader.data.src.input = testVectorNum; shader.data.src.width = SIZE/400; shader.data.src.height = 100; shaderJob = new ShaderJob(shader, testVectorNum, SIZE / 4, 1); var time : int = getTimer(), i : int = 0; shaderJob.start(true); trace("TEST1 : ", getTimer() - time); } The problem is that I keep getting a error saying: [Fault] exception, information=Error: Error #1000: The system is out of memory. Update: I managed to partially workaround the problem by converting the vector into bitmapData: (Using this technique I still get a speed boost of 3x using Pixel Bender) private function testShader():void { shader.data.ab.value = [1.0, 8.0]; var time : int = getTimer(), i : int = 0; testBitmapData.setVector(testBitmapData.rect, testVectorInt); shader.data.src.input = testBitmapData; shaderJob = new ShaderJob(shader, testBitmapData); shaderJob.start(true); testVectorInt = testBitmapData.getVector(testBitmapData.rect); trace("TEST1 : ", getTimer() - time); }

• SQL SERVER – SELECT INTO with FileGroup or Partitionis Not Possible

  - by Pinal Dave

  The other day, I received an email from user and after a long time before I answer the question, I had to check the answer online. Here is the question - I want to create a new table based from old table, but when I execute following script it gives me an error. Is there anything I am missing in my syntax? SELECT *  INTO NewTableName ON MyFileGroup FROM MyOldTableName I faintly remember that this was not possible in earlier version of SQL Server but I was not sure if this feature was added in the recent versions or not. I quickly tried few syntaxes and referred online documentation and learned that it is still not possible in the latest version of SQL Server. The alternative is to just go ahead and change the default filegroup of any new table with following script. Though, I do not like change the default filegroup for new tables. It is possible that when I have changed the default filegroup some other code executes behind the scene by automated system or my colleague, it will be also created on new filegroup. ALTER DATABASE DatabaseName MODIFY FILEGROUP NameofFileGroup DEFAULT The reason this feature is not supported is that SELCT INTO is minimally logged operation. I seriously hope that some day in the future this feature get added in.

• samba share not on network after upgrading to Ubuntu 12.04LTS.

  - by Sylvain Huard

  I just upgraded an old Ubuntu box to 12.04LTS (machine named A-Ubuntu). This is an upgrade not a format re-install. All the accounts and config were preserved. The basic setup is a local network with 2 Ubuntu machines (let say A-Ubuntu, B-Ubuntu) and a MAC (C-MAC). Before the upgrade, all of them could see each other by their names not only the IP address. The local network has a D-Link Router where everybody is connected with RJ-45 wired etherenet (not wi-fi). Since the A-Ubuntu upgrade, we can't see this machine name on the Network and its name is not on machine list in the D-Link router anymore. We can see it's IP address only. I can't access A-Ubuntu from the other two by its name but I can ping it with its address (192.168.0.109). From A-Ubuntu, I can connect and see the shared samba folders on B-Ubuntu and C-MAC. But from B-Ubuntu and C-MAc, I can't connect to A-Ubuntu. Correct me if I'm wrong but this tells me that Samba should be fine and the real problem is that A-Ubuntu does not advertise its name on the Network so the D-Link does not have it in its table so nobody else finds it. After a lot of googling, I see that it is the job of avahi and mdns to do so. Those packages are running, I checked multiple config files for samba, avahi, mdns to see as if it is like the examples on the WEB and also similar to what I find on the working B-Ubuntu machine. This is the same. I did multiple service restart with samba, avahi, remove the firewall to make sure it does not block the hostname broadcast. I rebooted multiple time to make sure the update I was making were effective. Still, Can't see the A-Ubuntu name on the network. Any idea what it can be?, Where to look next?

• What are some good examples of exuberant in-game instructions for telling the player to repeatedly smash a button?

  - by Michael

  What are some good examples of exuberant in-game instructions for telling the player to repeatedly and quickly press a button or perform an action? I'm especially interested in examples in retro games (e.g., from the NES, SNES, and 1980-90s arcade eras), and I would love to see examples with text, graphics, or both. To illustrate, here are a few examples of the type of instructions that I'm thinking of: Smash the A button to lift something heavy! Toggle the joystick back and forth to break free! Quickly press the button to build power in a meter! I'm working on a 2D iOS game with retro-style pixel art, and there's a point where I want the player to quickly tap on a sprite to complete an action. I have a serviceable starting point -- the word "TAP" flashing with an arrow repeatedly moving downward beneath it: But it still doesn't feel quite right. I would love to see some actual examples from the golden days of 2D gaming to use as reference material. I know examples abound, but I'm just struggling to think of any concrete ones at the moment. Can you think of any examples of this type of thing in old games?

• Unavailable packages repository

  - by bitmask

  I'm running ubuntu 11.10 (oneiric) on this machine, and suddenly, apt is unable to update properly. If I ask it to update its package information, by running apt-get update (or alternatively telling the update manager to "check"), it succeeds for about 120 packages (more precisely, I get about 120 Ign/Hit notes) and then says it cannot find universe Sources and restricted amd64: Hit http://de.archive.ubuntu.com oneiric-backports/multiverse Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/restricted Translation-en Hit http://de.archive.ubuntu.com oneiric-backports/universe Translation-en Err http://de.archive.ubuntu.com oneiric/universe Sources 404 Not Found [IP: 141.30.13.20 80] Err http://de.archive.ubuntu.com oneiric/restricted amd64 Packages 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/universe/source/Sources 404 Not Found [IP: 141.30.13.20 80] W: Failed to fetch http://de.archive.ubuntu.com/ubuntu/dists/oneiric/restricted/binary-amd64/Packages 404 Not Found [IP: 141.30.13.20 80] E: Some index files failed to download. They have been ignored, or old ones used instead. I manually checked the de server and cannot find anything wrong with the stuff it's complaining about. Also it looks pretty much like, say, the us mirror. But oddly enough, the IP it lists, seems to point to a debian package server, which obviously does not contain ubuntu packages. So, is this a local problem that I can fix somehow (and if so, how?) or is there actually some server down right now?

• Dot Matrix printers setup...

  - by Parhs

  Hello! I am using debian which is similar to ubuntu. They have 7 dot matrix printers some very old like this one http://www.omnidatasys.net/product/desc_printer_ti880.htm which works from 1979 daily and at text is faster than many inkjects. I believe that it has his own language... Sending text to serial port (port server) prints garbage. However i think is prints only capital english up to 95 asccii and greek and the rest up to 127 i think greek capital.(special chip ) Sending english capital letters prints garbage i think but i amnt sure... i will try again... The other printer are ESC/P compatible and i use generic epson driver provided from ghostscript... However i think that sending text via lp -dpr1 filename It prints the text as a grafic...Changing from printer font face(courier,times roman etc) or pitch has no effect... I am wondering if is there any work arround for this? In AIX they claim that lp command printed output as text as it prints and cobol programs send raw text to to lp printers . However in AIX they use some custom filters for the printers and has more options for dot matrix printers.. I would like to know if there is a solution for this.. To avoid graphics mode for text and change font face somehow.. The most Straight-through approach would be to use no driver ,just send ESC/P from cobol but this requires too much work... Thank you again!

• Malaysian Airlines bans kids under 12, creates separate cabins in basement of flight

  - by Gopinath

  Kids are lot of fun to watch and play as long as they don’t start crying. Once they start crying it’s tough job for parents to calm them down and for people around it’s painful to be part of it. If it happens to be on a flight, it’s a biggest annoyance one can ever experience. Especially on long journey over night flights, it’s a nightmare for passengers if couple of kids are uncontrollable. After receiving many complaints from its passengers who are disturbed by kids in flight, Malaysian Airlines decided to ban kids under 12 in their regular Economy class cabins of new Airbus A380s. Parents with under 12 years old kids are allowed only in to special kids zone created in the basement of  the multi-storied jumbo flights Airbus A380s. May be parents with under 12 kids does not appreciate this move, but the rest of travellers would be happy. Back in June 2011 Malaysian Airlines banned infants in first class of its Boeing 747-400 jets. The CEO of Malaysian Airlines defended on twitter about the decision as first classers spend pricy amount for a comfortable journey.  So if you are a parent of kids  under 12, think twice before you book tickets on Malaysian Airlines.

• How important is graceful degradation of JavaScript? [closed]

  - by Stephen

  Should web developers continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled". It was difficult to log in, albeit the site seemed to generally work okay. (I wasn't able to vote up any questions.) I think this is a satisfactory approach to development. Imagine the effort involved in making all of the site's features work with plain old HTML and server-side logic. On the other hand, I wonder how many users have been alienated by this approach. We've all been trained (at least the good developers among us) to use progressive enhancement and to ensure our web applications' dynamic features degrade gracefully. Is this progressive enhancement just pissing into the wind, or do some of our customers actually utilize certain web services without JavaScript enabled?

• Virtualbox shared folder mount from fstab fails; works once bootup is complete

  - by Ben

  I've got Ubuntu 13.10 installed in Virtualbox 4.3. The host machine is Windows. I have a couple of Virtualbox shared folders being mounted by /etc/fstab. Until recently this setup worked just fine, but after upgrading from Ubuntu 13.04 and Virtualbox 4.2 (at essentially the same time) the fstab mounting stopped working. I get the following error during boot: An error occurred while mounting /home/benme/Documents. keys:Press S to skip mounting or M for manual recovery Pressing M for manual recovery and then trying to mount manually also fails: root@benme-vb:~# cd /home/benme root@benme-vb:/home/benme# mount Documents /sbin/mount.vboxsf: mounting failed with the error: No such device But if I instead skip mounting during boot, wait for Unity to start and then mount manually in a shell, everything works fine: benme-vb ~ % ls Documents benme-vb ~ % sudo mount Documents [sudo] password for benme: benme-vb ~ % ls Documents # actual file list omitted Note that when I mount manually I'm letting mount take all the options from /etc/fstab, and it works. This suggests to me that it's some sort of timing issue, where Virtualbox isn't "ready" to provide the shared file mounts at the point /etc/fstab mounts are run during bootup. Here's the fstab line, just for completeness: Documents /home/benme/Documents vboxsf uid=benme,gid=benme,dmode=774,fmode=664 0 0 Is there something I can do about this from the Ubuntu side? Or does anyone happen to know more about this from the Virtualbox angle? I've found an old report on the Virtualbox bug-tracker with identical symptoms, but in that case the user had updated Virtualbox without updating their guest additions and resolving that fixed the problem; this isn't happening here, I've definitely got the 4.3 guest additions installed.

• How to implement physical effect, perspective effect on Android

  - by asedra_le

  I'm researching about 2D game for Android to implement an Android Game Project. My project looks nearly like PaperToss. Instance of throwing a page, my game will throw a coin. Suppose that I have a coin put in three-dimensional that have coordinates at A(x,y,z). I throw that point ahead, after 1/100 second, that coin move from A(x,y,z) to A'(x',y',z'). By this way, I have two problems need to solve. Determine the formulas can be used to compute the coordinates of the coin at time t. This problem is under-researching. I have no idea to solve this problem. Mapping three-dimensional points to a two-dimensional and use those new coordinates (a two-dimensional coordinates) to draw our coin on screen. I have found two solutions for this problem: Orthographic projection & Perspective projection However, my old friend said that OpenGL supports to solve problems like my problems. Any body have experiences about my problems? Help me please :) Thank for reading my question.

• Fail to upgrade from 10.10 to 11.04

  - by Ana Solís

  I was using Natty for a while, but while updating to the new release there was a blackout and it wasn't able to finish and Ubuntu failed to load after that. I thought, no worries I got my files backed up and I still got my 10.10 CD I used to put Ubuntu in my computer in the first place. So I installed it again, with the plan of using the update manager to get myself with the current release... Except I get this error: W:Failed to fetch http://extras.ubuntu.com/ubuntu/dists/natty/main/source/Sources.gz 404 Not Found , W:Failed to fetch http://extras.ubuntu.com/ubuntu/dists/natty/main/binary-amd64/Packages.gz 404 Not Found , E:Some index files failed to download, they have been ignored, or old ones used instead. My internet connection is just fine, seeing as I'm able to post this, but I don't know what else to do. Tried to download Quantal in another computer and putting it on a DVD (since it won't fit in a CD...) and the stupid thing fails to load it, it skips it over and goes right back to Maverick... (not a faulty disk, it installed Ubuntu just fine in a friends computer...)

• installing ubuntu on SSD

  - by kunal

  Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

• How do I access shared folders on Ubuntu server from Mac OS?

  - by Stephen

  I have an old dell desktop running ubuntu 11.04, I also have samba installed on it. I'm trying to access the shared folders on the Ubuntu machine from my Mac, so I go into 'Finder', click on 'Go' and 'Connect to Server'. I type in the ip address of the ubuntu machine smb://xxx.xxx.x.xx and click connect, I can then see the list of shared folders from the ubuntu machine so I know its making a connection. But when I access the 'Music' folder I get an error message stating: There was an error connecting to the server "xxx.xxx.x.xx". Check the server name or IP address, and try again. Any thoughts anyone ? EDIT I have a external hard drive attached to the server, and the folders I'm trying to access are located on that external hard drive. The location of the folder is /media/HD-CELU2/test, so I think the path from Finder should be smb://xxx.xxx.x.xx/media/HD-CELU2/test, but having tested this, I'm still not getting in. P.S. I'm using Samba as I have a Windows machine on my home network as well.

• Why isn't Java used for modern web application development?

  - by Cliff

  As a professional Java programmer, I've been trying to understand - why the hate toward Java for modern web applications? I've noticed a trend that out of modern day web startups, a relatively small percentage of them appears to be using Java (compared to Java's overall popularity). When I've asked a few about this, I've typically received a response like, "I hate Java with a passion." But no one really seems to be able to give a definitive answer. I've also heard this same web startup community refer negatively to Java developers - more or less implying that they are slow, not creative, old. As a result, I've spent time working to pick up Ruby/Rails, basically to find out what I'm missing. But I can't help thinking to myself, "I could do this much faster if I were using Java," primarily due to my relative experience levels. But also because I haven't seen anything critical "missing" from Java, preventing me from building the same application. Which brings me to my question(s): Why is Java not being used in modern web applications? Is it a weakness of the language? Is it an unfair stereotype of Java because it's been around so long (it's been unfairly associated with its older technologies, and doesn't receive recognition for its "modern" capabilities)? Is the negative stereotype of Java developers too strong? (Java is just no longer "cool") Are applications written in other languages really faster to build, easier to maintain, and do they perform better? Is Java only used by big companies who are too slow to adapt to a new language?

• Code maintenance: keeping a bad pattern when extending new code for being consistent or not ?

  - by Guillaume

  I have to extend an existing module of a project. I don't like the way it has been done (lots of anti-pattern involved, like copy/pasted code). I don't want to perform a complete refactor. Should I: create new methods using existing convention, even if I feel it wrong, to avoid confusion for the next maintainer and being consistent with the code base? or try to use what I feel better even if it is introducing another pattern in the code ? Precison edited after first answers: The existing code is not a mess. It is easy to follow and understand. BUT it is introducing lots of boilerplate code that can be avoided with good design (resulting code might become harder to follow then). In my current case it's a good old JDBC (spring template inboard) DAO module, but I have already encounter this dilemma and I'm seeking for other dev feedback. I don't want to refactor because I don't have time. And even with time it will be hard to justify that a whole perfectly working module needs refactoring. Refactoring cost will be heavier than its benefits. Remember: code is not messy or over-complex. I can not extract few methods there and introduce an abstract class here. It is more a flaw in the design (result of extreme 'Keep It Stupid Simple' I think) So the question can also be asked like that: You, as developer, do you prefer to maintain easy stupid boring code OR to have some helpers that will do the stupid boring code at your place ? Downside of the last possibility being that you'll have to learn some stuff and maybe you will have to maintain the easy stupid boring code too until a full refactoring is done)

• Best practices: Ajax and server side scripting with stored procedures

  - by Luka Milani

  I need to rebuild an old huge website and probably to port everyting to ASP.NET and jQuery and I would like to ask for some suggestion and tips. Actually the website uses: Ajax (client site with prototype.js) ASP (vb script server side) SQL Server 2005 IIS 7 as web server This website uses hundred of stored procedures and the requests are made by an ajax call and only 1 ASP page that contain an huge select case Shortly an example: JAVASCRIPT + PROTOTYPE: var data = { action: 'NEWS', callback: 'doNews', param1: $('text_example').value, ......: ..........}; AjaxGet(data); // perform a call using another function + prototype SERVER SIDE ASP: <% ...... select case request("Action") case "NEWS" With cmmDB .ActiveConnection = Conn .CommandText = "sp_NEWS_TO_CALL_for_example" .CommandType = adCmdStoredProc Set par0DB = .CreateParameter("Param1", adVarchar, adParamInput,6) Set par1DB = .CreateParameter(".....", adInteger, adParamInput) ' ........ ' can be more parameters .Parameters.Append par0DB .Parameters.Append par1DB par0DB.Value = request("Param1") par1DB.Value = request(".....") set rs=cmmDB.execute RecodsetToJSON rs, jsa ' create JSON response using a sub End With .... %> So as you can see I have an ASP page that has a lot of CASE and this page answers to all the ajax request in the site. My question are: Instead of having many CASES is it possible to create dynamic vb code that parses the ajax request and creates dynamically the call to the desired SP (also implementing the parameters passed by JS)? What is the best approach to handle situations like this, by using the advantages of .Net + protoype or jQuery? How the big sites handle situation like this? Do they do it by creating 1 page for request? Thanks in advance for suggestion, direction and tips.

• Should I go with OpenGL to see my future in Game Development industry? [closed]

  - by Priyank

  Possible Duplicate: Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry? I tried Google but found quite old articles, so I am in search of an answer in context to year 2012. Hi all, I don't know if you will consider this question appropriate for this community but I am constantly searching for a perfect answer. What I have seen is that most of the games that are released these days are DirectX 1x based. Except for few games like Starcraft or Diablo which don't have high end graphics are using OpenGL. So I have few questions to ask. The platforms i would like to target are PC (windows), Xbox 360 and PS3 (must). Should I go with learning OpenGL to see my future in game development industry? Or should I shift to Directx? If I learn OpenGL first, will it be difficult to learn direcx then? Which API is most suitable for indie development? Which one of the two API's are better from coder's (programmer's) point of view? Like OOP and style of coding. Is openGL being cross platform should be the only reason to choose it over Directx? Even when vendors are not providing enough stable drivers for it. Thanks in advance. I have read this post, but I have few questions. Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry?

• Expiry time in notify-send notifications

  - by gsingh2011

  On my HP computer running Ubuntu 12.04, the brightness and volume increments were much higher than I wanted. On top of that, the notification for the volume was just plain wrong (0% sound did not correspond to 0 on the progress bar). So I decided to override these options with my own commands. I used CompizConfig Settings Manager to add custom commands to the brightness and volume keys (this couldn't be done in the regular settings because these keys were handled by the BIOS, unlike normal function keys). I used xbacklight to control the brightness and amixer to control the volume. The problem is that the nice notify-send notifications don't show up when I manually set the brightness/volume, so now I have to do that myself too. However, there are two problems with notify-send: The expire time option doesn't work You have to wait until a notification is finished before the next one comes up Before I overrided the brightness/volume keys, the system was able to send notifications without these two restrictions. Notifications disappeared within 3 seconds (instead of the default 10), and if I double tapped the volume or brightness button, the progress bar would immediately change to the new brightness (instead of showing the old progress bar for 10 seconds and then showing the new one). Since the system was able to do it, I was wondering how I can achieve the same type of notifications?

• Blank Screen at boot Ubuntu 12.04 - nvidia-current - Macbook Air 3,2

  - by soulnafein

  I've installed nvidia-current using the Additional Drivers application in Ubuntu 12.04. I need those drivers so I can use accelerated WebGL. After installing the drivers, and rebooting X fails to start and I have a frozen system/dark screen. Below is the content of Xorg.0.log How can I fix this problem?

The server is connected by LAN. On one computer running windows XP I can see the server but are not allowed to acces them. On another computer on the WIFI-net running win7 I cannot see the server at all but I can ping the server and I can see the smb-protocoll is running when sniffing with wireshark. I don't primarily want to use passwords, computers on the lan and wifi should be able to connect without any login-procedure. I'm sure my config is not sufficient but have hard to understand how I should do. Theres a lot of descriptions on the net but most is old and none have been of any help. I'm also confused by the fact that I can not se the sever on my win7-machine even though it communicates with the samba-server. Would be very happy if anyone could spread some light over this mess.

• HDMI video output not working for external monitor

  - by user291852

  I have installed from scratch ubuntu GNOME 14.04 with gnome-flashback on my old HP HDX 16 laptop (core 2 duo p8600 + nvidia GT9600M + 4GB of ram) and I have problems with the HDMI output (I use it to extend my desktop on a dell U2412M 1920x1200 monitor). In the following I summarize the configurations that I have tried: Using the open source nouveau drivers, only the laptop monitor works, no signal from the external monitor connected to the HDMI output. However, the output of the xrandr command show that the HDMI output is connected with the correct resolution 1920x1200 (I find this thing really weird). Nouveau drivers with VGA connection works without problems on the external monitor, but the image is blurry compared to the HDMI connection. Using the nvidia drivers (I have tried different versions: nvidia-331-updates and the xorg-edgers versions nvidia-334 and nvidia-337) the HDMI output works, but I have system instabilities, random crashes and display freezes. I can't even enter in terminal mode with ctrl-alt-f1, so I have to manually shut down the laptop with the power button. I really would like to use the HDMI output with the nouveau drivers to avoid the system instabilities that I experienced with the nvidia drivers, but I can't figure out how to make it works.
