Re: How do I request a Domain Name from a Windows Local DNS?

I don't quite know what you want to do but I will explain what I do and that might help. I run webservers on my linux computers at home that I want to occasionally access from work as one of the webs allow me to monitor and control my home. At work I use a Windoze computer. In addition, the company ...

Re: RISC OS included in OS types reviewed in Linux Format

I do have simple sensors connected directly to the linux computer. What I don't what to do is use the linux computer to decode or encode complex waveforms for data exchange over RF and Powerline networks. There are perfectly good modems available that do this; the ones I have all include PICs - very...

Re: X11VNC headless resolution

In /boot/config.txt, I set

hdmi_force_hotplug=1

and

hdmi_group=2
hdmi_mode=16 (1024x768@60Hz)

Then I ran x11vnc with -configure 1024x600, which is the resolution of my netbook screen

Re: RISC OS included in OS types reviewed in Linux Format

I am struggling to think of any home automation that needs time accuracy down to 1ms. In my experience, controls cause changes state that take less than 0.5 sec. The energy measurement sends a reading every 6 minutes, the odd several seconds do not matter. Temperature sensors send a reading when a c...

Re: RISC OS included in OS types reviewed in Linux Format

While at a certain level home automation needs good timing, this tends to be handled by PICs - akit to a modem. The linux computer is being used as a supervisor, it gets messages from the various sensors and switches and runs a set of rules to decide what to do about it. this can be logging in a dat...

Re: RISC OS included in OS types reviewed in Linux Format

A ranking is nonsense, imo. Both OS have their advantages and disadvantages, making one or the other suitable for a certain task. E.g., for building/home automation no one (hopefully) would use Linux (so zero out of n stars), while RISC OS might get n out of n stars ... as long as there isn't OS-9 ...

Re: Introduce yourself!

Hello, I am Peter. I live my wife in Hampshire, UK. I am an engineer and have been using computers since 1976. My first experience was a CDC Cyber that understood George 3. My second was a PDP11 that ran RT11 and was booted by toggling in a code on the front panel. When I started work, I went on to ...

Re: Raspberry-Pi compared with Sheevaplug

I have two sheevaplugs and a dreamplug. One sheevaplug is a spare, the other controls my home and the dreamplug is a proxy for the sheevaplug. My first sheevplug blew its power supply and has had some SD card problems, which was all sorted out with the help of NewIT. Otherwise they all run very reli...

Re: New to RISC OS? Read this!

Their are two operating systems that I remember enjoying using in the past, one was Apollo's Aegis and the other was RISC OS. Last time I was using an Archimedes, the big argument was that it was not 'true' multitasking. It is interesting that one the arguments for RISC OS are that it uses cooperati...

Re: Interface Raspberry PI with x10 to read/switch statuses

I have been using X10 in my own home for years. My house is on a single phase and I have no trouble sensing X10 signals across the powerline - it works most of the time. It takes about 1/2 second to switch a light, which isn't too bad. I run 'heyu' on a very low power (5W) Debian linux computer, wit...
