Re: Nvidia Geforce Experience Security Vulnerability

I feel like almost nobody writes real code any more. Apollo Guidance Computer. Got Apollo to the moon and back. 16-bit words 2,048 words RAM (4K) 36,864 words ROM (72K) Assembly language, and RAM/ROM in core rope memory. Smaller than an Arduino Mega. :) Fully agree with the last art of writing code...

Re: Need some advice about microphone purchase

Or pick up a ModMic-4. It will be cheaper than the mic you selected plus the pre-amp/phantom power supply for it, and it will attach to your headset.

Re: Headphones on a Plane

I used M40x's in the office, but I consider them too bulky for flight travel, even though they do fold up nicely. I carry a decent set of isolating ear-buds for the airplane. I use a soft-rubber pair of tips for comfort though they do lose a bit in isolation, being only a single layer. But, they are...

Re: How recursive is the real world?

I've used recursion in walking paths across networks for diagnostics. You may have tunnels and you need to know which nodes the path traverses, including all the nodes the tunnels traverse. I've also seen recursion bite badly, it led to a stack smash that caused a 10G line card to reboot while runn...

Re: Optical Media Stream

Yeah, what JBI said. Pins 5 and 6 will provide a voltage that represents the current being pulled. The voltage drop across R2 will be fed to an op amp and amplified before being sampled. Pins 1 and 2 will give a voltage that can be divided down and sampled to get the line voltage. Pins 3 and 4 give ...

Is it likely that anything using a "tree" structure (directories, devices, whatever else) should naturally use recursion? Maybe that could be abstracted more into "anything where you do something, and depending on the results you might do it again with different data" As a gener...

P3 Kill-A-Watt meters do have the ability to compensate for power factor. That said, I don't know how accurate that compensation is. Yeah, my thought is that it's not the power factor that's the issue, it's that they are assuming the current waveform is a sine wave like the voltage waveform. In oth...

Re: Optical Media Stream

My guess is that it's a relatively cheap power supply with poor or no power factor correction and the meter is a "cheap" power meter that is interacting very poorly with the power waveform generated by the supply. If the meter simply measured peak voltage during the voltage cycle, peak cur...

Re: Optical Media Stream

I wouldn't trust your meter then. A PowerEdge T110 has 305W rated power supply. I don't think it's possible for that system to burn $50 of power in a month, at the prices you state. I would be surprised if it was over 150W at idle.

$50 a month would be quite excessive. $50 a year would be more in line, but low. My main storage server is an Intel OEM 2U "Grizzly Pass" chassis with a pair of E5-2650 processors, 32GB of memory, and 16 1TB, 7200RPM, 2.5" drives. It averages around 170W. My VM host has 8 600GB drives...

The Grados and M50x's should be ok on a mobile phone. My M40x's work just fine on my Moto G4 and they are rated at 35 ohms. The Sennheisers are getting to the point where an amp might help.

My Zyxel USG 50 can do it as well. It's been EOLd and replaced by the USG-60 (or USG-60W if you want wireless too). Not cheap if you buy new, but you might be able to find a used USG-50 for a good price.
