I'm no video expert, so correct me if I'm wrong, but I thought you can do 3840x2160@60Hz video with 24bit/pixel with under 14.4Gbps, which is the HDMI 2.0 limit [0].

According to this [1], that signal would require 12.54Gbps, so with a link budget of 34.56Gbps - 2*12.65Gbps, you'd have about 9.48Gbps left over for USB and ethernet (which is on the PCI bus for this particular hub). I suppose these numbers include coding overhead for the physical link, but I can't say for sure. If you wanted more than 60Hz or more than 24bit/pixel, you'd definitely run out of bandwidth with two monitors and USB/ethernet.

It depends on the configuration you're interested in, but there are some _relatively_ inexpensive ones from Monoprice [0]. I've tested this one with dual 4k monitors @ 60Hz, and USB 3. It works reliably, which is the most important aspect for me. No laptop charging and fixed TB cable however.

Thanks!

I can’t recommend Migadu. I used them for a year, and I spent many hours dealing with delivery issues and somewhat frequent unannounced outages/upgrades which go unreported. Spam filtering is generally broken and ignores whitelists. They tend to respond to about 50% of support emails, the last one being rather petty when I left the service.

I should have seen the yearly plan fee as a sunk cost and moved on sooner. Hope this helps someone else.

That sounds good!

How do I do this? What's transcript?

Based on the Wikipedia entry [0], it looks like 6PPD binds to the extra oxygen atom in ozone to convert it to regular O2, so it would be used during the life of the tire to prevent cracking.

I just read that ozone will cause cracks in regular rubber bands over time, I never knew that was the cause [1]. Interesting.

Solid-state relays provide isolation between the control circuit and the load, which makes it easy to deal with voltage differences between those circuits, which happens frequently when there is some distance between them. Those relays can be built with MOSFETS or other doped semiconductor switches.

It currently looks like CA will face a 54B budget deficit for 2020 [0], and "could see" a "one-time surplus" of $26B for 2021 [1,2], followed by projected deficits in 2022-25 [2].

How does Montana deal with that problem differently?

Probably for the best, since it will come from your pocket.

Diesel was getting phased out anyway, you can see that in the chart by the bump in gasoline vehicles.

Is this the connector problem where the screen doesn’t turn on?

Yep it was related to that, even though AppleCare ended up replacing my screen after 6 years (not 5 like I initially remembered). It was an unexpected bonus and I’m still quite happy about it. But the key was to call AppleCare directly and not go to the geniuses.

Free range eggs by end of 2021 right?

This is great! Hopefully Lidl will have them in other countries as well so I can buy them.

AppleCare for the Macs is definitely worth it. They even replaced the display on my MBP after 5 years when I called (that seems to be the key is to call someone at Apple directly). This was a part they should've recalled, but anyway I wouldn't have gotten a new display without AppleCare.

Pay for hosted email. You can always get human support if you pay for e.g. MS Exchange. Use a custom domain, so you can switch providers if needed. There’s no substitute for having control.

ICE vehicles aren’t front-heavy like that, it would be terrible for braking performance.

Can confirm, I’ve seen a dual-meter setup for garden water in Germany.

In France, you end up paying a lower tax on your vehicle the more children you have, so a family with four children might pay the same taxes on a large diesel as a childless couple with a tiny gas car. I was trying to register my 3-cylinder 1.0 liter vehicle, just to find out I’d have to pay 1500 Euro tax for my gas guzzler. Ugh.

I wouldn't pay too much attention to this particular issue, whatever is politically correct today will keep changing over time.

But apparently not enough for most people, otherwise no one would want an ICE car anymore.

US CO2 emissions per capita have been declining significantly since 2011.

Cities went from horse-drawn carriages to automobiles because the incentives made it attractive to do it. The same can be done for for electric vehicles, it’s just a matter of putting the horse in front of the cart.

Every layer in the storage hierarchy is "just a cache" in front the layer below it, so the naming is somewhat arbitrary. L1/L2/L3 caches are transparent from the perspective of the processor - it only sees a change in access times to main memory.

Any advancement in the storage hierarchy means reducing latency at one level or increasing the amount of memory at that level.

Most caches would use SRAM instead of DRAM, but the technology used doesn't define its role. Microcontrollers often have only embedded SRAM, serving as main memory.

Right, but I’m not trying to determine Apple’s markups. I just want to know where to buy a new Mac for myself. I don’t care who gets the markup, Apple, the gov’t, whatever.

Since you use words like “misleading” and “honest”, I wonder what your agenda is. Maybe you’re an Apple shareholder who’s allergic to any perceived criticism.

Oh ok, gotcha. I’m not trying to blame any entity here, just pointing out the price difference that’s larger than the sales tax difference between the EU and CA. Interestingly HK prices for iPhones are almost exactly California prices (within a couple of dollars) even though there is no sales tax in HK - that’s probably on Apple.

That's true, I'm comparing local purchase prices with currency conversion rates. The rest depends on your personal situation and tax jurisdiction.

1917€ would be about $2262, and $1699 pre-tax would be about $1699*1.095=$1860 with tax, or about $402 more expensive.

I'm comparing retail pricing in France (with a 2-year EU warranty) to business pricing in the US (with a 1-year warranty). That comes out to 1949€ including VAT in France, or about $2299 USD, vs $1749 USD including Los Angeles/CA sales tax with business pricing.

About 31% more.

Apple positions itself as being on the side of the consumer, and while they never really justified their soldered-down RAM (on laptops), one _might_ argue that it reduced failure rates. It's interesting that IBM discovered that soldering RAM to the individual compute modules in the Blue Gene/L (ca. 2004-2007) did improve reliability, in part because they had 2^16 modules in one cluster. I don't really buy that argument for laptop RAM, and especially not for SSDs, but I'm not sure if there's anything that can push back against Apple other than plain old competition, which they're trying to distance themselves from as much as possible, of course.

I did include CA sales tax (in Los Angeles) of 9.5%, vs the VAT-inclusive price in France/Germany/Italy, and the difference _after_ including those was about 30% higher in the EU. Germany was the lowest, probably because they temp. reduced their sales tax from 19% to 16%.

I can actually get a round-trip economy flight (pre-COVID and now) to LA just to buy a Mac mini, and save about $400. It's really.. unfortunate.

The most important feature of an M1-based Mac will likely be OS support into the distant future. I'm still using a 2012 rMBP, which was the first-gen retina version, and it's held up much better than any other computer I've ever bought, partly due to OS support into 2020. I imagine Apple will stand behind this new generation for a long time as well.

The new M1 SOCs max out at 16GB RAM, which seems like a major limitation, but the timing and latency of this integrated RAM is probably much better than what you could otherwise achieve. Meanwhile, improved SSD performance will probably have a larger impact on the whole system. I remember when I bought a 15k RPM hard drive ca. 2005 - it was like a new computer. Upgrading the slowest part of the storage hierarchy made the largest difference.

One slight disappointment in the Mac mini is the removal of two USB C / Thunderbolt ports and no option for 10G ethernet vs. the Intel model. An odd set of limitations in 2020.

Overall, at the price they're offering the Mac mini (haven't really considered the other models for myself), I think it's ok to take the plunge.
