  • Code hot swapping in Erlang

    - by Roger Alsing
    I recently saw a video about Erlang on InfoQ, In that video one of the creators presented how to replace the behavior of a message loop. He was simply sending a message containing a lambda of the new version of the message loop code, which then was invoked instead of calling the old loop again. Is that code hot swapping in Erlang reffers to? Or is that some other more native feature?

  • Disable automatic Date parsing in HtmlUnit

    - by submonoid
    Having just upgraded to a newer version of HtmlUnit (2.4), I've noticed certain tests are failing when comparing the output of asText. Looking into the differences, this is because dates (present on the page in the format 11/06/2010 00:00z) are being altered in the output to read 2010-06-11. Has anybody else encountered this, and can anybody advise how to turn off this (seemingly undocumented) feature of asText, which seems to go completely against the advised documentation.

  • Flash ActiveX: How to Load Movie from memory or resource or stream?

    - by yuku
    I'm embedding a Flash ActiveX control in my C++ app (Flash.ocx, Flash10a.ocx, etc depending on your Flash version). I can load an SWF file by calling LoadMovie(0, filename), but the file needs to physically reside in the disk. How to load the SWF from memory (or resource, or stream)? I'm sure there must be a way, because commercial solutions like f-in-box's feature Load flash movies from memory directly also uses Flash ActiveX control.

  • Parallel computing in .net

    - by HotTester
    Since the launch of .net 4.0 a new term that has got into lime light is parallel computing. Does parallel computing provide us some benefits or its just another concept or feature.

  • Are there legitimate uses for JavaScript's "with" statement?

    - by Shog9
    Alan Storm's comments in response to my answer regarding the with statement got me thinking. I've seldom found a reason to use this particular language feature, and had never given much thought to how it might cause trouble. Now, I'm curious as to how I might make effective use of with, while avoiding its pitfalls... So my question is, where have you found the with statement useful?

  • Motion - takes snapshot without motion detected

    - by Emmanuel Brunet
    I've been installed the standard motion 3.2.12 package on debian 7.5. I would like to get snapshot ONLY when motion is detected, but it still saves a picture every second without any activity in front of the camera. I'm using a TENVIS JPT3815W IP camera motion.conf here is my configuration file setup_mode off target_dir /media/videos/log/webcam netcam_url http://webcam/snapshot.cgi netcam_tolerant_check on netcam_userpass admin:alpha1237 # Output frames at 1 fps when no motion is detected and increase to the # rate given by webcam_maxrate when motion is detected (default: off) webcam_motion off output_all off # detection settings 1-255 default 32 noise_level 50 # Maximum framerate for webcam streams (default: 1) webcam_maxrate 25 pre_capture 0 framerate 25 gap 30 locate on mail [email protected] text_right "FRONT CAMERA %Y/%m/%d - %T" text_double on ffmpeg_cap_new on ffmpeg_cap_motion on ffmpeg_video_codec mpeg4 output_motion off snapshot_interval 0 # Quality of the jpeg (in percent) images produced (default: 50) quality 90 # Restrict webcam connections to localhost only (default: on) webcam_localhost off # Limits the number of images per connection (default: 0 = unlimited) # Number can be defined by multiplying actual webcam rate by desired number of seconds # Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate webcam_limit 0 Issue when I start motion images are stored in /media/videos/log/webcam nearly every second. I hjust want to get images when a motion is detected and the according video clip Any idea where the configuration fails ?

  • Why am I getting tree conflicts in subversion?

    - by Greg
    I had a feature branch of my trunk and was merging changes from my trunk into my branch periodically and everything was working fine. Today I went to merge the branch back down into the trunk and any of the files that were added to my trunk after the creation of my branch were flagged as a "tree conflict". Is there any way to avoid this in the future? I don't think these are being properly flagged. Thanks.
