More beautiful noise..... I really like noise This is A/C hum from the 240v (plus or minus) standard line voltage here (using an "unplugged Arduino UNO" as my "antenna"):
I've always liked noise on scopes and analyzers.... it's kinda hypnotic ....
Have you noticed how much more beautiful noise is, compared to a "clean" 1 KHz reference signal?
I was wondering is there something out there for Solaris 7 for screen capture?
Also it would really help if there was some software out there that can record whats happens on the screen for like 10 seconds or how ever long I need it to.
I did a search but doesn't seem to be alot out there. (10 Replies)
We are using Solaris 10 for our Radiation Treatment Planning and need to create a simulation for our service engineers. I need a screen capture tool that can not only capture screens, but create movies of mouse movements (similar to Captivate). I have contacted Oracle and talked to several people... (2 Replies)

It will capture an audio recording of any time length within the limits of OSX's QuickTime Player's capablility...
A shell script derivative of this will be used as a further capture for CygWin's AudioScope.sh.

Hello everyone!
I'm developing a MacOs Application in python and I'm having some issues trying to find information related to the power button pressed event. I know that in Ubuntu 14.04 you can find information about it on the acpi folders, but I realized that here in Mac that process is... (0 Replies)
Interestingly Apple has decided to switch the default shell for new users from bash to zsh in MacOS Catalina (10.15)

Sadly, I have turned off my access to the Apple Developers Beta program after installing macOS 10.15 Catalina a few days ago.
After the install, I rebooted by MacBook Air and it "hard froze" and we were heading out of town so I grabbed a backup MBA running Mojave.
Then, after getting back at... (10 Replies)
Just a quick note for macOS users.
I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which... (6 Replies)
Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story.
So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and in particular the ESPWROOM32.
I installed the... (0 Replies)

yuvycsnoise - Noise filter specialized for NTSC Y/C separation noise
SYNOPSIS
yuvycsnoise [-t] [-m t|b|i|c] [-S MIN] [-T ERRT[,MAXT]] [-B ERRB[,MAXB]] [-I ERRI[,MAXI]] [-C ERRC[,MAXC]]
DESCRIPTION
If video capture hardware has only a poor Y/C separator, at vertical stripe (especially red/blue), noises appear which seem checker flag
and bright/dark invert per 1 frame. yuvycsnoise reduces noises of this type.
OPTIONS
yuvycsnoise accepts the following options:
-t test. Instead of noise reduction, noises will be marked as black pixel.
-m METHOD
(default: tbic).
Select method. METHOD is string in which each character mean method.
t: 'triframe' method of luma noise reduction.
b: 'biframe' method of luma noise reduction.
i: 'infield' method of luma noise reduction.
c: chroma noise reduction. use 3 frames as 'triframe'.
-S MIN (default: 4).
Set minimum threshold of luma/chroma difference which is treated as noise.
-T ERRT[,MAXT]
(default: 32,255).
-B ERRB[,MAXB]
(default: 32,255).
-I ERRI[,MAXI]
(default: 16,255).
-C ERRC[,MAXC]
(default: 12,255).
Set threshold of luma/chroma difference of each methods. ERRx is maximum error of luma/chroma of pixels around target pixel, which
should be same if target contain noise. MAXx is maximum threshold of luma/chroma difference of target pixel from luma/chroma after
noise reduced.
