> It also means that if an app is no longer in the app store, there is no way to get that app back even if it would otherwise still work on your phone.

This is what I hate since iOS 10 and the removal of app sync in iTunes (and with the latest iTunes, apps are completely out without any alternatives). I've avoided upgrading iTunes as well as macOS for this reason. I don't want to sacrifice convenience and waste time spending hours re-downloading all apps from the App Store when I could get it a lot more quickly from a local copy. Apple just doesn't seem willing to recognize how bad connectivity is in most places around the world.

I wait in the hope that Apple will bring out some kind of "Sync" app that's separate from iTunes but works with it to easily backup apps as well as data on computers for quicker restores.

Eurozone Economy Records Strongest Growth in a Decade
We actually ended up using this when writing a controller for a quadcopter[1]. Essentially, we have one PID controller operate on the absolute angle (error = desired angle - actual angle). The output of this controller is fed into the second controller as the desired rate of rotation (RoR) (error = desired RoR - actual RoR). The output of the second controller is finally fed to the motors.

Apart from being easier to tune, I just found a good article[2] for why this approach works better for problems such as this. For quadcopters, of course, this allows one to easily switch between rate/acro mode and angle mode.

Android App Development: Just How Profitable Is It Really?
> how have you come to this conclusion / explanation?

Through personal suffering while working on firmware for UAVs (PX4/Ardupilot), CNC controllers (grbl, Marlin), inverted pendulum balancing exercises, RC car control etc.

Sadly, no resources. I guess the best advice I could give on this subject is: increase the visibility of internal state of the system. I have lost track of number of times I've seen people trying to tune PID controller just by outside observation (hmm, looks a bit better than last time) instead of real-time plots of measured process error.

Add high-resolution logging, look at the plots of error and P/I/D terms, have a simulation where you can replay the sensor values and observe the system output.
This will hit everyone using non-iOS Apple products either sooner or later:

You're no longer Apple's priority. You haven't been for some time. MacOS isn't getting major updates, the development team has been largely disbanded: MacOS is a niche platform that only exists to develop iOS apps. One day it won't even do that.

Apple already markets and wants iOS to replace your laptops, and doesn't significantly care about the server or workstation markets.

If you rely on MacOS you need to think about this, and the longer you delay it the more it's going to hurt.

It has an excellent reputation for stability and security among it's client base (which is not the same as actually being very secure, mind). It has good (albeit expensive) commercial support. It works well with most desktop and mobiles OSes. It's easy for non-technical users to use it. Etc, etc.

He criticizes people arguing for smaller cars closer together as being a linear solution to an exponential problem, but mass transit is also a linear solution to the same problem. Build better mass transit, and houses near the stations become more attractive and people move there, which increases usage, and so on. And looking at it from the other end, ever smaller cars jammed ever closer together at the limit tends to the same density as mass transit. (We're nowhere near that now, but I can see us getting much, much closer in an automated driving future.)

The key differences end up being routing flexibility, packet size and latency. Mass transit is worse in all three (less flexible and more waiting time are given with mass transit; I'm taking packet size to be a measurement forced space sharing, so big is bad). Its only real advantage is being at the limit for density, a density cars will likely never be able to match. But because it's still linear, it's only a constant factor improvement.

> I just linked to the first article I found that talked about the subject. And it's interesting that you look for something lazy instead of addressing more serious issues like Newton's model vs Einstien's.

You should give links you're willing to stand by. I didn't go looking for something lazy, I went looking for talk about fundamental physics (where Occam's Razor is appropriate, and what we're talking about) and found only the barely even wrong throwaway line about M-theory.

> Very clearly the (much!) more complex answer is more correct than the simple one.

Newton and Einstein don't make the same predictions. When you include the amount that you'd have to add on to Newton's theory to generate the predictions Einstein gives you about the behaviour of light, Einstein ends up simpler.

> Here's [1] another link discussing the issue and gives 2 examples.

The "new particle" example shows the opposite of what's claimed. Bethe's only reason to dismiss a new particle as an explanation was Occam's razor. The part about Newton/Einstein is just wrong about the history; relativity wasn't developed as an effort to explain the orbit of Mercury, it was developed out of Maxwell and Lorentz's work on electromagnetism. A universe in which the only reason to believe relativity was those deviations in the orbit of Mercury probably would be a universe in which the true theory was Newtonian gravity with small correction terms, not a universe in which relativity was true.
FWIW, you can't share APFS formatted volumes via AFP at all. AFP is probably not something you should depend on going forward.
I am not worried but instead welcome the integration of their chips to protect the integrity of my machine's data from hackers or even government agencies. That I fully support and expect to see.

I do seriously doubt they will move away from an Intel compatible platform, at most if they did then perhaps AMD chips. If Apple took their Macs away from Intel compatibility I doubt I would buy a new one and it would put into question the ability to maintain what software library that exists for the platform.

People are holding Tether and don't realize it. Most BTC/USD exchanges aren't BTC/USD exchanges, they're BTC/USDT exchanges, but that "T" is stuffed behind an asterisk. People that want to make profits don't realize they're not actually cashing out for $10k, they're cashing out for 10k USDT.

As soon as they wired USD to one of these exchanges, they were stuck holding USDT. They could take the BTC and run to another exchange like Kraken, but that has transaction fees associated with it and they don't want to lose ~10% of their investment.

How long does it take to reformat 300TB of disk? I guess the most time it takes is the restore from backup, because that seems to be the safest and easiest way to do this. But I might be wrong here.

I can see the problem here, and it's annoying that Apple doesn't handle this better, and doesn't give you any insights whether they will solve this or not. But I'm pretty sure that reformatting solves this problem for him a lot faster than waiting for a bugfix.
Easy solution: Don‘t use Macs as servers, they are completely the wrong tool for the job.

> Nowadays, I purchase iMac18,2’s to realize it has no thunderbolt2

Another tip: Read up on the hardware you are buying. I can‘t believe this guy... buys hardware seemingly without even looking at the specs and then complains.
Clearly your server is obsolete ... and this describes why my last ever Apple purchase was in 2012.

I bought an iPad 1 ... it's still a wonderful piece of hardware and I (try to) use it for web browsing nearly every day. Unfortunately, Apple realized that it was under-powered just after the iOS 5 release and it hasn't gotten updates since early 2014. It works fine except that it also doesn't have a browser that will run current protocols and standards. Sigh!
It might be nice if Apple did something more to convince us they care though. Make a strong statement? A commitment to quality?
GameMaker Studio used to do something like that. You started off with a specific version and then could buy plugins for additional features like compiling for consoles, Linux, etc. I haven't looked at the GMS2 pricing model so I'm not sure if they still follow that though.

Apple has been removing features from OS X for a while now, and I’m sure it’s going to continue with their focus on iOS. Eventually we will all be running iOS on macs.

I can see two alternatives to flying, sending a person, or a remote-control/autonomous ground based machine. The first one is not as productive, the second one is much more complex, and so more expensive.

"If I can't use SciPy to do the heavy graph algorithms and voronoi calculations and statistical models, what's the point?"

Some could claim that that is not really what 3D engines are for.

Large systems are better built from distinct parts. A large statistical calculation would not be a graphics computational job (unless you load it to the GPU).
I don't find that surprising at all: these are very large files, and they aren't probably not scrubbing around in them back and forth but streaming them off the disk in a single pass; so you could have 128GB of RAM and you are unlikely to get much caching on the files themselves... the only thing that matters is the directory index structures, and I wouldn't be shocked if they needed more than 16GB for that (because these are large files).
You need some hardware projects. Designing and building something like a 3d printer or cnc machine from scratch is quite rewarding. Here is a weekend project I did using 3 RC servos and an arduino:

To move 300TB (say, restoring a backup) at an optimistic 300MB/s would take just under two weeks.
A degree from a top school certainly helps. A masters or PhD in something like math or physics would be even better. I wouldn't say those are prerequisites but they would at least guarantee you an interview. If you don't have that, I would focus some effort on push based networking through any existing contacts you have. Get coffee with friends or friends-of-friends in similar positions and ask them about their job, if they're hiring, etc.

For interviewing, my experience in college was similar to @neerkumar's -- math and specifically statistics is going to be the most important. I applied to a Jump Trading internship just to see what the process was like. I was asked to solve 3-5 short puzzles, mostly based on probability and game theory. That was enough for me to know this isn't the field for me. ;)

I'm terrible at math so didn't get much further than that! I'm not sure what the coding components would be like, but it definitely depends on what position you're applying for. Some, like DevOps positions, probably don't even rely on the math, but you would get to work with really cool tech in low latency trading systems.

I read his post, and wonder if the 'attorneys' he consulted are specialists in EU law, or were his standard ones. There's a lot of FUD around GDPR but the guidance is getting better, and people assume it's being 'policed' when the UK's body (the ICO) is more about guiding into best practices than punishment.

The comments (esp around medical records) suggest ignorance of how it's working.

A good idea is not just the idea itself, it also considers feasability of execution. Saying execution is less important than an idea that you can execute well is a tautology.
The article helpfully addresses a lot of this.

The majority of the article talks about the town that they excavated that existed for precisely this reason. The evidence strongly suggests that the residents were very well looked after.

They also speculate that the town was populated as a consequence of a form of feudal duty called bak. This feudalism is documented but isn't known to have been used specifically to build the great pyramids (though it seems likely).

On the assumption that this is true, the lack of family accommodation etc is entirely plausible: the workers are seconded to the town for periods rather than live there full time.

I would really recommend reading the article, even if you're not an archaeologist. It's very interesting what you can learn from the evidence.

Apple sold these Macs as servers ... I even had one that was a 1U rack-mount unit. Businesses (unless you're a hosting service) generally depreciate server hardware on at least a 5-year schedule so it's no surprise to me that these are still in the field. It would be very interesting to know exactly how many are still out there running!
Add to this the macOS Server components will be significantly deprecated soon:

It's not a tech issue, it's a business issue. Why give people bigger raises than they may otherwise ask for? That's just wasting money. It's the same logic for why you only get a good deal when you threaten to leave your mobile phone provider. They don't want to proactively reduce your rate or make it too easy to get a discount otherwise they might be doing it unnecessarily.

The squeaky wheel gets the oil.

With work, it's also about an employee's best alternative, and also the psychology of "well, you used to work for x, so we'll only pay you a small increase since that's obviously what you'll work for". It's as much the psychological aspect as anything else since it's difficult to decide the "price" of something without any reference (i.e. a new employee).

High Sierra has been nothing but a smooth update for me. APFS has corrected several external disk issues I've had. All in all, it has been a solid, if small, update, similar to the other releases like Snow Leopard and Mountain Lion.

A HW question: how are all these cards attached to the system? IIRC the cheesegrater Mac Pros only have 4 PCI slots.
Firstly, Apple has never been a respected actor in the server market. If you're investing heavily into Apple servers, you're investing in a niche. Presume accordingly. Secondly, converting/reformatting 300 Tb of disk is a lot of work, but it's probably less work than contacting Apple, and whining about how Apple is going down the drain in a public blog post.

I've never been a big Apple fan in terms of the company, but the iPhone is an excellent product. The iPod was an excellent product. I have never heard anyone say that in terms of server infrastructure, Apple makes "excellent products". The only lesson here is: don't drink the kool aid, and investigate every use case thoroughly without making emotional assumptions.

edit: Despite knowing almost nothing about AFP, I found articles on Google saying that Apple shifted from AFP file sharing to SMB2 in an article dated 2013 -- that's five years ago! Apple themselves state that AFP is deprecated. If you elect to run your own servers and support your own services completely, these are news you should be reading.
Apple switched to SMB, AFP is done.
Right.

I suppose Jarrett would say that if a place is dense enough to have more than occasional traffic jams, then it already is too dense that its transport problems can be solved by road construction.
Surely "slaves built the pyramids" implies that at least the majority of people involved were slaves. The article inverses that simplified statement, implying the same caveat: at least the majority of people involved weren't slaves (though some might have been).

If slaves were present in the society, it's absurd to interpret a blanket statement like "not slaves (built the pyramids)" to imply no slaves were involved, especially when it's a direct response to the blanket statements "the pyramids were built by slaves" (which noone would take to mean that no non-slaves were present anywhere near the construction site -- it's a given that someone would need to oversee the slaves somehow).

But we're literally arguing over semantics. Unless you assume that all generalisations are always intended to be understood 100% literally and that archeologists would want to express 100% confidence in knowing exactly what group in society each person involved in a construction project thousands of years ago belonged to, there really isn't anything worth arguing over.

General ignorance has it that the pyramids were built almost entirely by slaves. This article claims that is not the case. Everything else is just fluff to make for a better read.
