Oh, I definitely agree that the most prudent decision a few years ago was to avoid Tesla like the plague. Why would Apple, the most profitable company in the world, want a nearly-bankrupt car manufacturer on its books? Nevertheless, with th

How so? Apple could have bought a big chunk of Tesla and flipped it back to the public market for ~10 times the price today, for a cool $500B+ profit. Even if they wanted nothing to do with the company's operations. Of course, such an

If you don't want the chip to throttle, the simple answer is to get the Macbook Pro, not hack together a crappy laptop from a Mac Mini :) Even then, the throttling on the Air seems pretty minor. About ~30% drop in performance after it

Aside from what other people have mentioned already, there's one more trick. The Chase Freedom Unlimited gives 1.5 points per dollar on all purchases, which can be transferred to the Reserve and spent at 1.5 cents per point. Effectivel

Until mid 2021 several other things also count for the travel credit such as gas and grocery stores. Chase probably did not want a wave of card cancellations over the $300 credit being mostly useless during the pandemic.

Not just masks. Early projections (March / April) by supposedly reputable groups like IHME were wildly inaccurate. Even a cursory reading of their methods showed that they had no idea what they were doing. Oversimplifying a bit, they w

Many of the tech companies are in the "bad" neighborhoods. Most notably Uber, Twitter and Square are all headquartered right next to one of the worst parts in the city (Civic Center / Tenderloin). I remember walking to one of

Back then a software engineer at a well-known big company would make around $30-50k (not inflation adjusted). Combined with 1993's interest rates (~7%) $300k was quite steep. Today the same engineer at a FAANG would make about $300k. H

Hardly any of this matters in userspace or device-independent kernel modules, which is what 99% of developers work in.

I like Apple's approach of having more narrow vector units rather than a few extremely wide ones. Narrower vector units are generally easier to program and easier to support on small cores (like the efficiency cores). It's a good

This is an oversimplified statement. Extra decode width only helps if the rest of the CPU can actually process so many instructions in parallel without blocking on other resources like memory. x86 CPUs also have their own features to allevi

Old server hardware can be very cheap, although it's not necessarily the best value. Typically it only makes sense if 1) you need a lot of memory, 2) you don't mind a slightly higher power bill and 3) you don't care about sin

Yes, consider vector floating point fused multiply-add (FMA). On a typical AVX implementation like Skylake, this instruction has a latency of 4 cycles and a throughput of 2 instructions per cycle. To avoid stalls, you'd need 4 * 2 = 8

You're making completely the wrong comparison. On the left you have Geekbench 5 scores for the A12Z in the Apple DTK, and on the right you have Geekbench 4 scores for the Ryzen. The M1 has leaked scores of ~1700 single core and ~7500 m

Refurb 12" Macbook? Wish Apple would reintroduce those with the M1. Awesome form factor, held back by Intel's anemic Core M CPUs.

They're lithium-ion batteries with carbon fiber electrodes. Doesn't matter what kind of battery it is though, once you start cutting through them you are very likely to short the electrodes together. Which usually ends in fires.

Apple's perf/watt is much higher than AMD. Anandtech has the A14 within a few percent of the 5950X on single threaded workloads. Power consumption is 5 watts (entire iPhone 12) versus 49 watts (5950X package power). Normalizing fo

You'll want tensor cores, so I would stick to the 2000 or 3000-series Nvidia cards. Not to mention the headaches of using AMD cards with any ML framework.
