Re: Headphone market for 2018: Hot mess

It is the reverse for me. I was using an iPod Touch connected via Lightning but I found that audio from my iPhone via BT was way more powerful. It is as if the wired connection was wrongly set at a lower sound level. There's this thing called a volume control. Maybe you've heard of it? That's not t...

Re: Headphone market for 2018: Hot mess

Bluetooth audio doesn't use anywhere near all of that though, and you're still transcoding from one lossy format to another for transmission. But like I said above, Bluetooth audio quality is generally "good enough". Biggest issue I have with it is that the Bluetooth audio on my LG G4 gli...

Re: Headphone market for 2018: Hot mess

So anyway, I'm in the market for some bluetooth headphones. I think I can live with this Sennheiser headset for $100. I love my HD280 and I've got this mental block of spending more than $100 on a pair of ding dang headphones. It would be a bit ghetto, but you could Velcro something like this to yo...

I don't think fans are particularly susceptible to ESD. I agree you'd probably want to keep it away from the motherboard/GPU though.

Re: Drive bay activity LED stopped working, but only for a specific drive

I mostly use it to run VMs from, so if it does die, worst case I need to run VMs from a HDD instead until I replace it. So annoying, but not a show-stopper.

Drive bay activity LED stopped working, but only for a specific drive

My desktop system has a dual hot swap 2.5" bay. For a while I've had a Toshiba THNSNJ512GCSU (512GB SSD) in one of them. For some reason, the activity LED on the hot swap bay no longer shows activity when the drive is being accessed. The drive still works fine, and I just tried another drive in...

Re: Headphone market for 2018: Hot mess

Yeah, what Airmamtharp said. USB cannot carry analog signals, so the DACs are in the headphones, by definition. So it all comes down to the quality of the DACs used, and how well they filter out any noise on the power rails. In general the headphones will be in a "cleaner" environment from...

In the developer's defense, it would be nice if the C API didn't require you to select different functions to perform the same operation based solely on thread safety or lack thereof. The C community is loathe to change the way things have always been. The APIs, IMHO, are much more sane in C++, at ...

In fact, hand-optimized assembly can be good for a while, but then might not perform as well over time as the CPU architectures change. Case in point: recent optimization work in glibc that improves performance noticeably by moving away from old hand-optimized assembly that was good on old CPUs but...

Re: My home theater is sounding weird

Yes. Any exposed hard, flat surfaces will create acoustic reflections. Covering them with something soft and/or non-flat will help absorb and break up the incoming sound waves so that more of what reaches your ears will be coming from the speakers, and less of it from reflections.

Buckethead - Attic Garden (2016)

Half hour of whacked out instrumental experimental metal from the man with the KFC bucket. Much of it is frenetic and/or dissonant, but it also has occasional mellow ambient interludes. One of his better "Pikes" releases, IMO. I really like this!
