Comment Re:Now when voltage regulators fail (Score 4, Informative) 188

The other rails are a throwback to the 1980s and 1990s when TTL logic ran at 5v and later 3.3v. Today's logic don't run on 3.3v* or 5v or 12v; components run on less than 2v (sometimes less than 1v) and are highly sensitive to crosstalk and power droops.

It is simply not practical to build a PSU that supplies hundreds of amps on tiny, sometimes variable, voltages, on isolated rails with shielded cables for every component. As a result, devices today treat the PSU as a sort of mains power and implement their own converters and regulators to provide each component what it needs.

Motherboards have VRMs, GPUs have VRMs, drives have VRMs... a modern PC is full of them. So why bother with an assortment of legacy PSU voltages if they're just going to get reconverted anyway?

(*This is a bit of a simplification; there are plenty of native 3.3v components in a modern PC but they tend to have trivial power requirements)

The X-37 launches at the tip of a rocket inside a protective fairing, so it won't have the Space Shuttle's problem of ice and foam breaking off the external tank and damaging the orbiter. It also doesn't have all the life support systems to drain and recharge, main engines to replace after every launch, or an interior to refurbish between flights. And it's a lot smaller.

Since the X-37 isn't man-rated, the standards are significantly lower, too. If they needed to, they could probably have it flight-ready again in a day.

But if it allows cameras with the same sensor to be thinner than current designs, it could also allow for cameras with larger sensors to be as thin as current designs. In theory, metamaterial lenses could result in DSLRs you can slip in a pocket. Which would be amazing.

Loud music is the aural equivalent of lasers and strobe lights. Unless you're operating a club please don't harass your employees and customers with it.

If silence is a problem, textured ambient sounds can give your business far more personality than blaring the Billboard Top 40.

These days everybody carries around earbuds and a smartphone. If people actually want to listen to music, they will.

The 20xx series aren't bad cards, but the prices are ridiculous.

780ti launch price: $699
980ti launch price: $649
1080ti launch price: $699
2080ti launch price: $1199

nVidia screwed gamers twice, first by not raising production when demand spiked, then by maintaining their supracompetitive pricing even after the shock ended.
Even when profiteering is legal it generates a lot of ill will with customers; in a few months, if AMD's Navi isn't complete garbage, expect a lot of formerly loyal nVidia users to switch camps.

To be fair, nVidia has become a sort of advanced douchebag boyfriend to its core market.

"Hey babe, you know how I treated you bad last year since I was busy with that side piece? Well the bitch went crazy and dumped me, so I'm going to need you to put out for me a lot more since I'm used to two girls now and I got standards to keep up. And on weeknights wear this blond wig and let me call you Crypto."

In Jobs' time the machines tended to get cheaper over time, even with new designs and incremental improvements every year.
Once Cook took over, spec bumps have slowed and prices ratchet up with each redesign.

I bought a first generation Retina MBP for $2900. To get a replacement MBP today with the same clock speed, RAM, and storage, I'd pay about $2800. Six and a half years later. That's not progress.
