• Simplest way to host a domain name just so i can forward it to a wordpress blog?

  - by Max Williams

  Hi all. I have a domain name, and a wordpress account. The domain name isn't hosted anywhere at the moment. I just want to set it up so that my wordpress blog uses the domain. According to the wordpress help page on this issue, i have to do the following: Update your domain’s name servers to the following. Make sure to remove any existing name servers that are already there. NS1.WORDPRESS.COM NS2.WORDPRESS.COM NS3.WORDPRESS.COM So, this is the only thing that i need a server for - if i even need a server at all? Is there a really simple way i can do this for free? Or for very cheap? I'm a bit ignorant about this stuff: i do rails coding but don't get involved in the really technical stuff to do with servers and dns and what have you.

• Blackberry (Java) - Setting scrolling be not focused on objects on the screen

  - by paullb

  I have a mainscreen which currently scrolls (and I have the arrows on the right) but the scrolling seems to be focused on the ButtonField objects that I have on the page. Is there any way to set the scrolling to be non-focused scrolling (moving a few pixels each time). Is there a way to set this? Other ideas I have had (which sound hacky so I want to avoid): - Placing NullFields around to scroll - Manually listening to the trackwheelRoll event and moving appropriately

• Primary monitor keeps reverting back to the laptop display

  - by Celeritas

  A Macbook Pro running VMware Fusion has a guest operating system of Windows 7. The user often connects an external monitor to the laptop through an HDMI cable. For the display settings "extend the desktop" is selected and I keep setting the primary monitor as the external one but for some annoying reason it keeps changing back. So after Windows starts the taskbar and icons are on the laptop screen which we don't want. I know how to change it but it keeps changing back (and the computer user is non-technical).

Why don't rename at once?

• Semantics of repeated acknowledgments in JMS

  - by Lajos Nagy

  Suppose I decide to call acknowledgment() on a JMS message several times. Say the first call fails (for non-permanent reason). Does the success of the second (or any subsequent) call guarantee that the message is now acknowledged? Is the exact behavior of acknowledgement() specified anywhere?

• How best to integrate PPA into Debian?

  - by eicos

  I'm working with ZFS on Linux, on my Debian squeeze server. I've found a useful package in an Ubuntu PPA, apparently by one of the ZoL developers, and I would like to integrate it into my package system. However, I am really having a terrible time doing this. It seems like it would be possible if I upgraded my system to the testing branch, but I'd prefer not to do this for obvious reasons. So, what is the One True Way to do this? Or, what is a passable way to do this, i.e. one that does not involve an ice nine-like assimilation of my entire system to testing branch? Edit: Silly question. I clicked the little green "technical information about this package" on launchpad and all was revealed.

• Tutorials about the Silverlight Navigation Application template?

  - by AngryHacker

  Silverlight's Navigation Application template seems promising, however, I can't seem to find any tutorials (particularly video tutorials). Whatever I did find was from the beta and is inconsistent with the released version. Has anyone seen any non-beta tutorials (particularly video)?

• How can I identify whether a browser/reader is being used by someone who is visually impaired?

  - by Mark Brittingham

  I have to provide a 508-compliant version of a page for the visually impaired and it isn't practical to just modify the page. Thus, I have created a new "reader-compatible" version of the page for the handicapped. The question is how I can tell if someone is using a reader rather than a standard browser? Is there a "header" or "useragent" value typically used by these non-standard browsers that I can look for? Thanks in advance!

• Profiling tool for Clojure?

  - by j-g-faustus

  Hi, does anyone know of a good profiling tool or library for Clojure? I would prefer something that could be used from the REPL, along the lines of (with-profiling ...) in Allegro Common Lisp back in the day. Is there anything along those lines? Or do you have any experience with (non-commercial) Java profilers that work well with Clojure?

• remote desktop computer viewer?

  - by Josh

  I would like to install a quad core computer in my dorm at college and use my much slower laptop to be able to control the quad core just as if I had a quad core laptop (control as in i see the gui, not command line control)! Both are on the same college network, though Im also interested in what would be necessary if the computers were on different networks. What would be the best method fot this? Im looking for non-lag communication.

• Changing keyboard layout on application focus

  - by Anonymous Coward

  Hi Everyone As everybody knows the en-US Keyboard-layout is the best one for programming. So I'd like to use it in my IDEs. But since I live in a non-en-US country I need the de-CH layout for all other applications. Now I wonder if it is possible to set the layout depending to which application currently has the focus. If that is possible, can a human brain adapt to such a behaviour or is it just confusing? cheers, AC

• How can I validate two or more fields in combination?

  - by DR

  I'm using JPA 2.0/Hibernate validation to validate my models. I now have a situation where the combination of two fields has to be validated: public class MyModel { public Integer getValue1() { //... } public String getValue2() { //... } } The model is invalid if both getValue1() and getValue2() are null and valid otherwise. How can I perform this kind of validation with JPA 2.0/Hibernate? With a simple @NotNull annotation both getters must be non-null to pass validation.

• How to replace a region in emacs with yank buffer contents?

  - by Mad Wombat

  When I use VIM or most modeless editors (Eclipse, NetBeans etc.) I frequently do the following. If I have similar text blocks and I need to change them all, I will change one, copy it (or use non-deleting yank), select next block I need and paste the changed version over it. If I do the same thing in emacs (select region and paste with C-y), it doesn't replace the region, it just pastes at the cursor position. What is the way to do this in emacs?

• Why no Win16 support in 64-bit Windows?

  - by dsimcha

  My understanding (from Wikipedia) is that the x64 instruction set supports executing 16-bit protected mode code from long mode, but cannot execute real mode code without being switched out of long mode because long mode lacks virtual 8086 mode. Therefore, it stands to reason that real mode DOS apps can't be run in Win64 w/o software emulation or dynamic translation. However, why was support for Win16 protected-mode apps excluded when support for them seems (at least at first glance) to be reasonably implementable and is included in newer versions of Win32? Was it just a matter of demand not being high enough to justify implementation costs (and the win32 version was already implemented), or is there a good technical reason?

• X264 encoding using Opencv

  - by user573193

  I am working with a high resolution camera: 4008x2672. I a writing a simple program which grabs frame from the camera and sends the frame to a avi file. For working with such a high resolution, I found only x264 codec that could do the trick (Suggestions welcome). I am using opencv for most of the image handling stuff. As mentioned in this post http://doom10.org/index.php?topic=1019.0 , I modified the AVCodecContext members as per ffmpeg presets for libx264 (Had to do this to avoid broken ffmpeg defaults settings error). This is output I am getting when I try to run the program [libx264 @ 0x992d040]non-strictly-monotonic PTS 1294846981.526675 1 0 //Timestamp camera_no frame_no 1294846981.621101 1 1 1294846981.715521 1 2 1294846981.809939 1 3 1294846981.904360 1 4 1294846981.998782 1 5 1294846982.093203 1 6 Last message repeated 7 times [avi @ 0x992beb0]st:0 error, non monotone timestamps -614891469123651720 = -614891469123651720 OpenCV Error: Unspecified error (Error while writing video frame) in icv_av_write_frame_FFMPEG, file /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp, line 1034 terminate called after throwing an instance of 'cv::Exception' what(): /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp:1034: error: (-2) Error while writing video frame in function icv_av_write_frame_FFMPEG Aborted Modifications to the AVCodecContext are: if(codec_id == CODEC_ID_H264) { //fprintf(stderr, "Trying to parse a preset file for libx264\n"); //Setting Values manually from medium preset c-me_method = 7; c-qcompress=0.6; c-qmin = 10; c-qmax = 51; c-max_qdiff = 4; c-i_quant_factor=0.71; c-max_b_frames=3; c-b_frame_strategy = 1; c-me_range = 16; c-me_subpel_quality=7; c-coder_type = 1; c-scenechange_threshold=40; c-partitions = X264_PART_I8X8 | X264_PART_I4X4 | X264_PART_P8X8 | X264_PART_B8X8; c-flags = CODEC_FLAG_LOOP_FILTER; c-flags2 = CODEC_FLAG2_BPYRAMID | CODEC_FLAG2_MIXED_REFS | CODEC_FLAG2_WPRED | CODEC_FLAG2_8X8DCT | CODEC_FLAG2_FASTPSKIP; c-keyint_min = 25; c-refs = 3; c-trellis=1; c-directpred = 1; c-weighted_p_pred=2; } I am probably not setting the dts and pts values which I believed ffmpeg should be setting it for me.

• rpxnow - How to promote users to sign in

  Since adding rpxnow to our website, less users are signing in. Are these readers worried about giving their (eg hotmail) password to a third party site? Has anyone found a good way to promote use of rpxnow (or other openid managers) as a secure method of authentication to non tech savvy readers?
