IMO the fact that it's not available around the world (although apparently this is soon about to happen) alongside the high price for a device that still needs to prove that its not a novelty, along with what must be a whopping Bill of Materials which means that even at $3500 the economics of it aren't working out that well, nor does it have the insanely great wow factor in terms of it having that lacklustre front screen show the logistics of manufacturing the thing haven't been appropriately resolved. Ok it's a first generation device, but its sheer non-appearance in the real world shows that its release wasn't properly thought out and implemented. And Apple were really in no major rush to release it, because it's not like they were in a fight with Meta even if they were perhaps quietly freaking out about the Quest.

But ultimately it's a logistics failure because what is Apple's main USPs? The Apple Stores across the bloody globe – none of which outside the USA have Vision Pros to play with. Ok they're keeping it in the US for now (due to logistics reasons) but Apple is sitting on a cash mountain of how many tens of billions and it can't arrange to put a few Vision Pros in every Store in the world for kids to go in and play with?? Even if the device is "a few months away" that would be one major logistics fail. Build the hype of a device that people really need to try to understand. Get kids playing games on it and interacting with AR Pokemon (or whatever) while their parents are buying new iPhones. Apple could spend two billion dollars on manufacturing a million of these to throw everywhere and not even blink – pocket change for them, and for launching a wholly new class of product. Me saying they've flubbed it is actually being polite, as a shareholder and long term Mac luser, I think they've completely fucked it up. Do you know what I mean?
Nice deflection. Perhaps you'd like to address which points you feel are incorrect?

Can't wait for it to backfire
The problem is the spreading of it, and given human social dynamics, there is no permanent solution.
Well, friction and execution risk aren't exactly the same thing as I understand it, and it's not really "repurposing" the military term as much as it is using it in a broader context than it was originally used in. A lot of military stuff is simply one particular usage of some field: deciding how many subordinates a general should have is a military usage of organizational dynamics; getting bullets from the warehouse to the soldier is logistics; friction is simply a property of complex systems regardless of what the system is

You might, I certainly don't. Corporations aren't your friends and aren't something to mythologize

They make money because they sell popular products and collect 30% of a lot of other companies operating on the things they sell

Hype died down along with "microservices" where queues made more sense.
Helpful. Just got Quanta and Fields. Thanks!
I think it's very much your last theory -- used everywhere but not as interesting to tell people about as it might have been a decade ago. Queues are now Boring Technology(tm), and that's a good thing.
You haven’t really countered anything the OP said.

Yes, the Vision Pro is a leap forward technologically. So was the iPhone. But how many products on the way to the iPhone didn’t get released because Jobs (or someone else) realised it wasn’t a compelling offering to customers?

The Vision Pro feels like a tech demo. I can absolutely imagine Jobs being impressed by the tech and canning it nevertheless, waiting for a better application.
What was the "wow" factor of M2 Macs over their M1 counterparts?

M1 absolutely floored naysayers who didn't think an ARM chip could be "good"

M2 seems to be just M1 "but we made it a little faster!"

The fact M3 and M4 aren't even really filtering down into most of their computer offerings definitely doesn't help
We all learned that a distributed monolith is worse than just having a monolith. Truly independent event-based systems still are very useful, but not when they have to communicate stuff back and forth to achieve a single problem.
The magnitude is important as well as the sign.
Sure, or more precisely they need to be able to draw a box around the power intensive step where they can cheaply store a buffer of the inputs and outputs, and have excess capacity for that step.

Like I'm not an expert on fertilizer production, but it seems pretty likely to me that you could draw that box around ammonia production and build out capacity that relatively cheaply, while leaving what I imagine to be the more operationally complex and capital intensive steps of extracting phosphates (via sulphiric and phosphoric acid) and potassium (which has nitric and sulphiric acid as biproducts), and combining that nitric acid with the ammonia (into ammonium nitrate) alone.

In some cases if you have excess production capacity (because you have unpredictable or seasonal load and you aren't currently at a peak) you don't necessarily even need more production capacity at all, just the ability to store a bit more of the inputs and outputs in a buffer.
Sadly it's a dying art form. 40-50 years ago every scientific university department used to have a scientific photographer to allow the researchers to publish their photos in articles. My own godfather was a scientific photographer who retired and started commercializing scientific photos.

Unfortunately now, due to shrinking budgets and the proliferation of iPhones the need for such photographers is vanishing.
I think it's also important not to underestimate how chilling of an effect Apple's locked down environment is having here.

Like the iPad, it's such a developer-hostile system to work in many devs aren't willing to take the risk of risking time and money in an ecosystem where Apple can sherlock you or just refuse your updates for any arbitrary reason and where users have been taught that software should be disposably cheap.

Integrated into IDEA (and other IDE's)... so it checks as you type.
Andrew Bosworth (FB's blathering sociopath-in-residence) said Trump ran “the best digital ad campaign I’ve ever seen” and they even had marketing people embedded with the campaign to help them run more effective ads.

The final straw for me was in October of 2019 when Zuck had a closed door meeting with Trump and then "randomly" the next week announced that politicians are now allowed to lie in ads on facebook. Hmmm, I wonder who would disproportionately benefit from that policy change??

Was this article written by AI? It's a strange mix of really basic stuff and true advanced suggestions, jumbled together with no apparent organization scheme.

Then the "complex tasks" are just a couple basic system administration examples that I can't figure out the purpose of either, they don't show off most of the tips mentioned above and don't really help inspire a sense of power for shell scripts.

Pretty much.

Capitalism demands there to always be a lower class to exploit and Africa is getting the short end of the stick, both from western countries and even China whose itching to support their state-ran capitalism as much as they can.
I believe this is one of life's questions where there is no right answer. I've lived from the alternative perspective: I decided to stay closer to home to be near my parents. But my decision isn't necessarily the right one for every person. I've spoken with older individuals who regretted missing out on professional and personal opportunities that they could have explored in another country, and their experiences inform my response.

A principle I've tried to follow is to minimize regrets over one's life. In your case, it sounds like you will live with the full experience of moving to a new place—you won't have the regrets expressed by some who didn't move away. Some people who give up opportunities out of passiveness have grown to truly regret that decision. In my situation, closeness to parents was one of several reasons: if it were the only one, it’s likely I would have regretted not taking an alternate path.

You can also call your parents often over the phone or video. I was very close to a person who moved to the opposite side of the globe from the person’s parents for more than five years, but spent a lot of time video calling them (nearly every day). The person confided in them and talked about plenty of subjects. This person truly has a great relationship with them: I wouldn't be surprised if the topics of conversations were often deeper than those with my own parents, despite being half a world away.

It also may not be too late to move later in life (though understandably, sometimes there are barriers, such as a partner who can't easily move, or restrictions in either country that make a move difficult). Many people in my country move to the US to earn money and gain experience, then decide to move back home after a number of years to raise children and care for family members. From another perspective, I've known other people who moved to my country, then worked with immigration services to bring their family to move with them.

Though I don't know your parents, they might also have regretted or been heartbroken if you gave up on your dreams or plans in life just to stay closer to them. If I were to become a parent one day, I would also hope my children would similarly be able to live a full life, even if that meant an empty nest at home.

I think it's good that you are actively considering the question. A future step may not involve any person moving in the future, but a starting point could involve deepening the relationship with your parents by calling them and sharing more about your life.
He doesn't say that. Instead, he makes a vague proposal for a new filesystem that layers nicely on top of cloud block stores.

Filesystems take decades to change; NFS is not going anywhere (it's still huge in enterprise). It's still wholly unsuitable to a wide range of use cases, but that doesn't mean it must die.
I’d throw a [citation needed] on that. The App Store has, by all accounts, been a runaway success despite all the limitations you’ve listed. By and large devs are very happy to make apps within this system.
I think that’s just standard software engineering now. Like no one is struggling to build these architectures.
> ...why have a satellite waste time looking at the earth when it's dark? ...

Exactly. Many NASA Earth-observing satellites use the same kind of sun-synchronous orbit (https://en.wikipedia.org/wiki/Sun-synchronous_orbit). (One of several exceptions are the instruments opportunistically mounted on the ISS, which has its own orbit, as you note.)

One of these sequences is called the A-train (https://atrain.nasa.gov) - that's what OCO-2, discussed in OP, is part of.

Having it be near noon local time (1:30pm, say) when you pass over every patch of ground has great advantages for some instruments. The sunlight passes through less atmosphere, and does so in "the same way" for most passes. So you're not seeing some places at local dawn and others at local dusk. This makes the observation less sensitive to the difficulties of atmospheric modeling. (Because you need a good atmospheric model to retrieve the solar induced flourescence [SIF] signal.)

OTOH, the sun-synchronous orbit does restrict your observations to specific times. The companion instrument, OCO-3 (which is mounted on ISS), plays a special role here. OCO-3 can provide information about the daily cycles of plants that would be undersampled by a consistent 1:30pm arrival.

*

Separately from orbits: The discovery that you could obtain insights on plant processes at global scales from SIF using the OCO-2 measurement has been a really big deal for Earth science.

In that instance the M1 / M2 Macs aren't exactly a wholly new category of product, just MacBooks in basically the same form as they've been since the Powerbook, but now with an M1 chip. I meant the actual first release of a novel product – iPhone / iPad / Watch, all of which were good enough but became brilliantly usable after a couple of iterations.

Also, I'm writing this on an M3 Pro MacBook. Totally awesome machine, like Platonically good laptop, and doubly so now they ditched that "hat on a pig" Touch Bar and returned to actual function keys...BUT...I have so many cores I can barely even count them in htop and doing things like rendering in iMovie or adjusting the size of 100Mb RAW photos in Preview is STILL SINGLE THREADED. Preview even threw up a rotating beachball of doom and froze the other day when adjusting the size of a single large photo. Totally totally amazed a division of software engineers haven't been laid on to at least rewrite the utterly-parallelizable parts of the native apps on Mac OS. FFS.
Interesting to see this here. I've got one on order, with the intention of making a google maps direction HUD (→ 0.3 Boren Ave) for cycling as I never remember which are the ideal turns, dislike watches, and think it'd be fun.

Overall, the lilygo ecosystem is a lot of cool ESP tech, with surprisingly poor software and community support.
I had access to a Google Glass device through the university I worked for. This looks a lot simpler to develop for, and probably a good deal more usable as a heads up display for random stuff. Not to mention shockingly less expensive. Battery life on the Glass was also very poor. This can only do better on the battery front.
i think the easy bet for apple is to double down on video content. watching, creating, sharing 3d videos is supposely better than most TVs up there with imax
In 2006 Jobs introduced the iPod Hi-Fi, which wasn't much of a success either.

It was either behind the times (tin[n]y smartphones, including the iPhone that was already in development, killed powerful boom boxes as well as home hi-fi systems) or ahead of its time (medium and large sized bluetooth speakers were ultimately a successful product category.) HomePod was ultimately semi-successful, though more in its mini size I believe.

Jobs was ultimately right about the iPad (which currently outsells the Mac in terms of unit sales) but it took a while to catch on.
The App Store has made a lot of developers a lot of money. There are tons of billion dollar gaming companies for example. One viral game on the app store with a few cosmetic upgrades can net you a billion dollars.
It may be that lambdas (cloud functions, etc) have become more popular and supported on other platforms.

When you enqueue something, you eventually need to dequeue and process it. A lambda just does that in a single call. It also removes the need to run or scale a worker.

I think Kafka continues to be popular because it is used as a temporary data store, and there is a large ecosystem around ingesting from streams.

I personally use queues a lot and am building an open source SQS alternative. I wonder if an open source lambda replacement would be useful too. https://github.com/poundifdef/SmoothMQ
Queues are a tool in your distributed system toolbox. When it's suitable it works wonderfully (typical caveats apply).

If your perception is indeed correct it'd attribute it to your 3rd point. People usually write blogposts about new shiny stuff.

I personally use queues in my design all the time, particularly to transfer data between different systems with higher decoupling. The only pain I have ever experienced was when an upstream system backfilled 7 days of data, which clogged our queues with old requests. Running normally it would have taken over 100 hours to process all the data, while massively increasing the latency of fresh data. The solution was to manually purge the queue, and manually backfill the most recent missing data.

Even if you need to be careful around unbound queue sizes I still believe they are a great tool.
If you start to think about optimising the performance of your bash scripts it might be time to rewrite in another language
Neither did I. At the controlled area of the shipyard I've been in and out of recently those deemed important enough to need phones inside had ruggedized flip phones with no cameras, it felt like something out of 2009.
This is reality, att least in Sweden. You can invest in battery storage att your house and give control of it to the power company. They will then use the locally available power storage to either feed back to the grid or store excess of capacity and needed.

It can be quite profitable from what i heard, in relation to installing solar cells.
It’s important to keep in mind that 12 years ago, the patterns for high scale message queues (and often even low scale) were still in flux and getting established.

In the ruby world, delayed job was getting upended by sidekiq, but redis was still a relatively new tool in a lot of tool-belts, and organizations had to approach redis at that time with (appropriate) caution. Even Kafka by the mid 10s was still a bit scary to deploy and manage yourself, so it might have been the optimal solution but you potentially wanted to avoid it to save yourself headaches.

Today, there are so many robust solutions that you can choose from many options and not shoot yourself in the foot. You might end up with a slightly over complicated architecture or some quirky challenges, but it’s just far less complex to get it right.

That means fewer blog posts. Fewer people touting their strategy. Because, to be frank, it’s more of a “solved” problem with lots of pre existing art.

All that being said, I still personally find this stuff interesting. I love the stuff getting produced by Mike Perham. Kafka is a powerful platform that can sit next to redis. Tooling getting built on top of Postgres continues to impress and show how simple even high scale applications can be——

But, maybe not everyone cares quite the way we do.
> a strange mix of really basic stuff and true advanced suggestions, jumbled together with no apparent organization scheme

Sounds very bash-ish.
- message queues are still widely used and more cloud hosted than self hosted so you will see them less in arch diagrams

- event log (stateful multi-consumers) have taken a portion of the message queue workflow. this is more likely than moving them to redis/database

message queuing works incredibly well for many problems. it’s as critical to most companies architectures as an application database
I only learned recently, too!
> I don’t foresee it ever being there.

I understand where you’re coming from - have you considered how advances in AI Video generation might pair with a premium headset?

The output from Sora (OpenAI) looks pretty compelling already. I also recently read that Apple is already using AI image generation to create stereoscopic images from any plain old 2D image.

Combine all this together and it’s not impossible to envision (pun intended?) a halfway decent on demand interactive experience.

Kind of amazing to think a holodeck-like experience is in the not too distant future.
WWhat is misinformation? What does "solve" mean? (Is that the same as "what should be done about misinformation?")
>plus, it seems like DeepCompute sells their own RISC-V laptops which are (probably) more powerful than this thing:

Yeah. spacemiT K1 is a new chip, 8core, RVA22 with Vector extension.

JH7110 is old in contrast. Was first seen in VisionFive 2 in January 2023. Only 4 cores, slower, and RVA20 without Vector.

> the specific rule in California labor law mentions the 5 hour requirement.

You're not wrong here.

> This means Employees are basically required to take the meal break before 5 hours

I don't think this characterization is supported, though. For one, the law only applies to non-exempt (usually: non-salaried) employees, and for another, case law (typically citing Brinker) consistently holds that the employer is not required to enforce that the employee takes the full meal break at the appropriate time, merely that the employer provide opportunity to do so. The actual opinion from Brinker states:

> Specifically, we conclude that (1) while employers cannot impede, discourage or dissuade employees from taking rest periods, they need only provide, not ensure, rest periods are taken; (2) employers need only authorize and permit rest periods every four hours or major fraction thereof and they need not, where impracticable, be in the middle of each work period; (3) employers are not required to provide a meal period for every five consecutive hours worked; (4) while employers cannot impede, discourage or dissuade employees from taking meal periods, they need only provide them and not ensure they are taken; and (5) while employers cannot coerce, require or compel employees to work off the clock, they can only be held liable for employees working off the clock if they knew or should have known they were doing so.

https://casetext.com/case/brinker-restaurant-corp-v-superior...

One interesting application in case law that I found is that apparently being on-call during a meal break is sufficient to result in a violation.

Another benefit of higher-quality clothing is that it can be easily resold if you get tired of it or grow out of it, instead of dropping it in the dumpster or donation bin. Brands like Patagonia, stores like REI, and consignment stores will give you credit or money for your used stuff if it's from a known brand. But it's still more work than most people want to do, and it's still going to cost more than buying the cheapest possible item.

The only thing that isn't potentially misinformation is that which you witness with your own eyes. Since everyone has their own eyes, calling what they witness misinformation is known as gaslighting.

The only way to prevent people sharing their experiences is called censorship.

What you're really asking is "can we stop people from lying?"

The answer is no.
