I had a closable cover and someone shut my laptop with enough force that the cover caused the screen to break. Be careful when closing.

Was it a built-in camera cover, or a third-party one? Apple specifically (and possibly other manufacturers?) recommends against third-party covers because the tolerance is so close:

zlsa commented on We're excited about our new roundabout   wsdotblog.blogspot.com/20... · Posted by u/aendruk
zlsa · a year ago
I live near this roundabout and drive through it almost daily.

> Drivers going northbound on SR 203 traffic may need to yield twice – once when entering the roundabout and again if traffic is passing between the two islands. If you think about it, that’s just following the same rules a second time.

The one key difference from the average (American) roundabout is the second yield. After you've waited your turn and entered the roundabout, you're required to yield again within a few feet. Obviously this is not an impossible task, but the signage leading up to the roundabout from northbound SR 203 doesn't at all indicate the shape of the roundabout. The navigation sign at the entrance only shows a single roundabout.

The second yield point is indicated with the standard yield sign and triangle markings on the road. But judging by the amount of detritus scattered on the ground, as well as the recent addition of "YIELD" text painted on the road and orange flags attached to the yield sign (both not present at any other entrance to the roundabout), the yield-twice pattern is not obvious to everyone.

Plus, the topology of the roundabout isn't conducive to seeing this from the ground, either; the relatively sharp right turn leading into the roundabout places the second yield sign out of your forward vision when you're approaching the roundabout, and the whole intersection itself is very slightly tilted away from the northbound entrance, making it really tricky to see and understand it when approaching.

---

Anecdotally, almost every time I've driven through here while there is simultaneous traffic from northbound SR 203 and northbound 203rd St. SE, the northbound 203rd St. SE traffic ends up being cut off by drivers failing to yield at the second entrance.

I genuinely cannot read that roundabout from overhead, and I am not a person who has trouble with roundabouts. I think it would benefit greatly from an explanatory diagram. I do hope that it would be more obvious while on the ground, like you said.
zlsa · a year ago
Unfortunately, it's not. Driving from right-to-left (in the first picture) requires drivers to enter the roundabout twice, then leave once. Judging by the amount of vehicle debris generally present and the additional "Yield" markings and signage that have been added to the second yield point since the construction was completed, it's been confusing from the ground as well.

Sure, then try this one from HP with 16GB RAM and a CPU that benchmarks in the same ballpark as the M2, for $387:

The point isn't that the MacBook Air isn't better by some metrics than PC laptops. A Rolls-Royce is "better" by certain metrics than a Toyota, too. What makes a device luxury is if it costs substantially more than competing products that the average person would consider a valid replacement.

zlsa · 2 years ago
I'm not sure a machine that benchmarks half as fast as an M2 can be said to be in the same ballpark.

I didn't call it a "flop", I said it's status as a flop doesn't correlate to how good a product is. The Butterfly Keyboard never flopped, but it also never got a legitimate competitor. People bought them because they were forced to, same as they were with Airpods and arguably the Apple Watch.

I feel the same way about a lot of Apple products. The Magic Trackpad would sell out instantly if it got a new model with USB-C - but Apple knows they can ship more Lightning cables if they avoid it. It's part of the sinister math that goes into making you and I rely on Apple's constant... ahem, Innovation.

zlsa · 2 years ago
The Magic Trackpad comes with a USB-C (computer) to Lightning (Magic Trackpad) cable.

(I agree with you, for what it's worth - Apple is weirdly slow to update some of their products; AirPods Max stand out here as missing USB-C and the lossless audio of AirPods Pro.)

Using warhead explosion as garbage collector might seem like a clever hack, but all it takes is an upgrade by a different team (say, adding a new engine, or longer-range sensors, or repurposing a surface-to-air missile for a surface-to-surface role), and suddenly your guidance software runs out of memory before it explodes, and your missile falls onto an an elementary school or hospital.

Related: the Ariane 5 rocket failed on its maiden flight because it reused code from its predecessor, which made an assumption that didn't apply to the higher-performance Ariane 5.

Good.

I've been reading "Cobalt Red" How the Blood of the Congo Powers Our Lives and it is deplorable how the Congolese people are treated.

Maybe they'll discover or manufacture a material that can replace Cobalt that has the same thermal stability but by then it will be too late.

I mean, the Cybertruck starts at $39K, so it's right in line with other trucks available on the market in the U.S. They haven't really chosen a luxury price point. They clearly intend to mass market this thing. Pick-up trucks aren't vulgar, they're simply practical and useful.
zlsa · 2 years ago
It has been a while since they've talked about that price, and I would not expect it to be anywhere near that price point today, given <gestures at everything>.

You're exactly right. The Cybertruck an enormous misstep for the company. And the amazing thing is Tesla figured out with the Model S that if you make a nice sedan that happens to be electric—people will buy it. There were a lot of people with disposable income that want to help the environment, but wanted to drive something nicer and less weird looking than a Prius.

They should have taken the same approach with their pickup. People expect trucks to be able to haul, tow and have a certain amount of bed space. If they were serious about building a pickup, they'd build something like the Lightning—a truck that could do all of that, but happens to be electric. Heck, if they did that Rivian might not be in business.

The Cybertruck is a novelty item and nobody who wants or needs the utility of a truck is going to consider it over a Rivian or F-150 Lightning.

zlsa · 2 years ago
The Rivian has a 4.5 foot bed[0] and the F-150 Lightning has a 5.5 foot bed[1]. I don't think it's fair to call Cybertruck a novelty item based on its capabilities, especially compared to its competition.

(Of course there are completely legitimate downsides of Cybertruck - for example, with the sloped bed sides, it won't be able to tow a fifth wheel trailer. But that is a capability the vast majority of truck owners don't use.)
