Re: Replace Incandescent Indicator Lights with LEDs

Are you sure the power light is not part of a larger circuit? I've seen designs where the indicator was actually required to be within a certain tolerance for a design to work properly, and LEDs can certainly interrupt that if that 12V was actually AC...

Re: DIR 855L needs to be rebooted daily

This is how my Buffalo router's wifi chips died. First, normal (for ~2 years). Symptom #1 was sustained transfers dying over Wifi, quickly followed by total inability to stream even 1 Mbps video without Wifi dropping out. By the end it wouldn't even stay connected well enough to get to Google. Inter...

Re: Asinine System Requirements

It simply doesn't make sense from a technical or sales standpoint. I'm sure hardware vendors love it. I know that prior to my oversight, there were people at work that would buy whatever the vendors proposed...regardless of whether the hardware was actually needed. It wasn't their fault, they just ...

Eh, you can try it ofc -- but it drives a tendency to keep mucking around, and geeks then often end up down a rabbit hole of trying lots of different things that might work, because "this should work", and lose a whole lot of person time. Silly, IME, when a system restore is almost zero p...

Even if your time has less value than whatever intrinsic value you ascribe to having the newer driver, consideration should be given to the fact that by mucking around in this way it's possible to use up the system restore space and cheat oneself out of the easy/guaranteed option. :facepalm: A syst...

If you already have UPS setups in place for graceful shutdown, no, more is probably not needed unless your DR strategy is nonexistent.

A handful of kilowatts? An in-rack UPS is probably the easiest and most economical solution. This is just rack-scale UPS, which is a pretty sorted problem.

Re: Is there a point in using SFP over just normal RJ45 for gigabit?

Besides power and distance, there's no difference. The physical layer has nothing to do with the logical layer.

I disagree on 40 GbE being basically 4x10 GbE bonded - it's a single link that can be saturated by a single stream. The same is rarely true of bonded links.

I guess I am spoiled. If ever I created a subwoofer that didn't have at least 95dBSPL/1W I would consider it a waste of time. I am currently drooling over a subwoofer project called "Tuba HT". It may be a little overkill until I build my basement theater to contain the sound. Eh, efficien...

There are several rabbit trails there, but yes, with an efficiency in the 90dB+ range you can do considerably better than the average subwoofer, especially for just near-field listening (versus the whole-room listening I've seen many computer setups used for, including myself in times past).  RMS r...

It's not like 20 watts isn't enough for an efficient subwoofer to be obnoxiously loud... This re-states one of the enduring misconceptions about audio, unfortunately. The power requirements are not for low-level continuous listening, which is often only in the range of a few mW to a few W even at f...

Re: Is Sandy Bridge worth upgrading from yet?

I also wonder if Intel's SMT has improved much over the generations. Reviews usually test the new i7 against the previous i7, it's harder to see if the IPC differences between the i5s and i7s is growing each generation. I had a rough ballpark figure that HT was worth about 30% more than a single co...

Re: Is Sandy Bridge worth upgrading from yet?

Unless the second thread is sitting idle most of the time (i.e. the game is really single-threaded for all intents and purposes), I doubt an 11% clock speed advantage would allow a single core with HT to outrun two real cores. It depends, really. Game code tends to be quite branchy, and that's wher...

That's the crux of the problem. There is hardly any mainstream games and application that scheduled and thread correctly to effortlessly handle HT.

You couldn't be more wrong. HT does nothing for games and it usually causes performance issues with threading that end-up impacting frame-timing. Scheduled properly, HT helps keep everything else out of the way without impacting performance at all. I don't think I've seen any i5 versus i7 compariso...
