.So how did the tube radio help with your debugging?


Ben,

with the help of radio interference you can hear your computer working. (best in AM and SW Range, ok nowadays UHF? ) And you can hear if your program hang or running a fast or slow loop, listening to the interrupts.  Since the old tube radios are not shielded (wooden box, no PCB, all free wired )  they easely catch the electrons stop and go on your computer board Smiley Happy

It's a way like you don't need to look at the system load because you can hear the load of the power supply

BTW:  Bob Pease still recommend this way to troubleshoot circuitry. http://www.national.com/rap/Book/0,1565,0,00.html

I love this radio, and I still have the telefunken tube guarantee cards (expired now Smiley Wink  ) and the magic eye is still glowing..... http://www.jogis-roehrenbude.de/Roehren-Geschichtliches/Mag_Augen/Mag_Augen.htm

Wow, sounds like some kind of NSA spy activity......

I suppose recording something like that nowadays would be kind of impractical due to the increased speeds, but would it be possible to hook up a DAQ card to a similar system and record the code running on a ZX81?

That would be interesting....  You could not only have code which is pretty to read, but also pretty to listen to too.  A whole new area of programming aesthetics.

Re: ZX81 assembler I have to pass.  It was before my time.  I remember vaguely references to it when I was young, but the C64 was the first computer I really encountered.....  Assembler makes me shudder anyway.

PS I do remember the sound of the old tape-loaders of the "Amstrad CPC 464" and wondered how long it would take for someone to put some drum beats behind it and score a top 10 hit.  Thankfully some things don't come to pass.

I started using Labview in 2001,that time there were very less number of users in India and the companies using Labview for Revenues were only Small companies and i was worried about the career with LabVIEW

Latest Development and Marketing Startegies in indian region led the LabVIEW to be used by Big & Outsourcing companies and nowadays a many lot top companies including HCL Technologies,Texas Instruments,GE,Satyam,Infosys,Tata Consultancy Services,Patni Computer Systems,KPIT Cummins,L&T are using labview for Offshore development and a good tool to earn revenues....

Its a good to tool to work at and has good jobs assocaited nowadays

It has also been getting Best Software awards in India by Leading Magazines...

I recently read an article similar to this.  There is a study about using sounds to tell the IT team the "health" of the network.  A bunch of different sounds are generated based on events, such as a virus got intercepted, spam traffic level, etc..  It was a print, so sorry, I can't post a link... well actually, maybe I could. 

Who knows... maybe sounds could also be used in production 😉

That's a good one!

I can just see the new guys running out for the Snake Oil,   I mean "old tube radio",   to try and debug their code.


Although a radio may be nice to listen to during the three or four minutes it takes for LabVIEW 8 to launch.

Actually the ominous ping utility seems to have gotten its name just because of that. The original setup was a computer system where the output of a quickly put together testprogram that later got prominent as "ping" utility was piped to the system beeper to troubleshoot faulty network cables. A single person could then test the cable by walking through the building and moving and bending it and listening to the loud sound could in that way detect where a cable defect or bad connector might be located.

Audio feedback is a very powerful  technique. 🙂

I remember about 30 years ago I hooked up an audio amplifier to our old pulsed NMR spectrometer to listen to the FID for a student demonstration. I was amazing how much easier the shimmig was, just listening to the sound... If the field was inhomogenous, it sounded more like a

Thudddd...,

while with a prefectly shimmed magnet the sound was a beatiful

Dinngggggggggggggggggggggggggggggggggggggggggggggggggg.......

Just dialing the shim knobs while listeing would esily tell the righ direction to turn. 🙂 It is amazing how good the human ear is to sense even subtle differences.

(With a ethanol sample I was able to generate some nice harmonics by selecting a suitable reference frequency).
