> Given this architecture, how would read speeds drop by 35% from one model to the next? I'm not sure--my first guess was that fewer NAND chips were being used, but teardowns show that both 2018 and 2019 models were using two chips.

NAND flash is almost always packaged with a stack of several dies in each BGA package. Individual dies are typically 256Gb (32GB) or larger, and most manufacturers will stack up to 8 or 16 dies per package. So an SSD with two packages can easily vary from 128GB (2 packages x 2 dies per package x 256Gb per die) to 2TB (2 packages x 16 dies per package x 512Gb per die).

It's also possible for a single BGA package to have the NAND organized on one or more channels. Drives using larger form factors (eg. enterprise SSDs using 2.5"/15mm dual-PCB) will typically have each package connecting to only one of the SSD controller's channels, and often have multiple packages per channel. Consumer SSDs that need to minimize PCB footprint take the opposite approach, using eg. two packages connecting to two channels each to fully populate a low-end 4-channel SSD controller.

I don't know Apple's recent history of NAND choices, but it's possible they've switched from MLC (two bit per cell) to TLC (three bit per cell) NAND flash, which sacrifices performance for density and cost. They have probably moved to 3D NAND with a higher layer count, which can be a mixed bag for performance especially when the controller is not also upgraded. If they've moved to a higher per-die capacity for drives with the same total capacity, then a significant performance drop for lower-capacity models is expected.

Sure, they have a business reason to do exactly what they do but I think as people grow up they specialize and the general stuff that fits everybody becomes useless. Google tries to personalize search results but that so far yielded echo chambers, not personalized discoveries.

I can't get better products by searching Google, I can get the best-spammed products or most promoted products only.

The fact that I am getting low-quality service and Google is printing money means that there is a place for good a good service and if that service cannot emerge due to Google's practices, it probably means that the regulators need to take action.

Or maybe the search is dead, long live social media.

The gist is, I am not happy with a service but the company that makes that product makes a lot of maney. Can't tell if I am an anomaly or if other people feel the same way because Google is a monopoly and maybe the regulators should make it possible to compete with Google and see if there's a space for a better service.

Yes yes, I am the product but I am the product only if I am happy with the stuff I'm getting in return.

I wish they would call it something other than AI. Like "Diagnostics" or if there MUST be a buzzword there, then call it "Predictive Diagnostics".

Once upon a time, a necessary precondition to call something AI was that it should be something where there is at least the hope that it could one day generalize to pass the Turing test or something along those lines.

Medical diagnostics is one of the primary applications of pattern processing, and since it's pretty damned impressive as it is, it's a bit pointless to try and make it even more impressive by suggesting that you might one day enjoy a chat with your medical diagnostic tool over breakfast, exchanging views on how the Knicks' season is shaping up...

These seem like very unnecessary distinctions. "In the end", the plane had software that was supposed to do one thing but failed to do that, resulting in the plane crashing. These are very apt and natural comparisons.
No, that's when it's least interesting to ask what the hardware does. A program with UB will not reliably compile to any particular hardware behavior, so changing unrelated parts of the program or upgrading your compiler can change which hardware behavior you get.

The actual hardware behavior is useful for other purposes, like understanding why the abstract machine is the way it is, or understanding and improving the performance of well-defined programs, but it is not useful at all once you have UB.

those properties allow you to divide up work on data in a way that guarantees that no two processes will work on the same data at the same time. You can then take data, divide it up, use 'const correctness' in the language to guarantee original data doesn't change and then you don't need a mutex because you know only one thread is working on that piece of data.

A typical approach is if you can divide your algo into map/reduce, you can do this. Going back to the properties of you computation allows you to reason how to apply something like map/reduce.
Did I read it correctly? Threatened 'brain drain'? So 'brain drain' to US is being viewed as a positive thing?

I think the idea is to send people back to build their countries, not to stay here to build America. This is indeed a good news that we are spreading the talents and knowledge and eventually prosperity more evenly across the globe. US has enjoyed this monopoly over talents for too long, and that is probably not a good thing and definitely shouldn't be taken for granted.

I was curious about this, as I work in multiple languages every day. I almost never use Google though except as last resort if other engines can't find anything. So the result I got for array length was for Javascript. Which is quite high on the hype cycle now, but I only very rarely use it and search anything about it even less frequently.

Sо I wonder how much of the magic you perceive might be just your interests matching the interests of the most other people using Google and thus it's not just Google magically guessing you're into Javascript (for example) now, but Javascript being popular and this being the cause of both Google returning matches for it and you starting to use it? Did you ever do a clean experiment - e.g. try to learn APL or some other relatively obscure language and have Google return all results about APL and none about Javascript?

SLC caching is only used on consumer SSDs, and on most drives it is largely or exclusively a write cache.

LinkedIn has become plagued by self-help-like stories and other self promoting, vague and meaningless write ups, in my experience.

It wasn't always like this. I used to have a reasonably cool feed centered towards technologies and news that are at least partly relevant to me and my industry. No more. It's all 'I gave a homeless person lunch and today they are the #1 duck breeder in Brazil' or some other nonsense.

I don't know when this started or if it is localized, but it renders the 'place to find useful information' aspect of social media completely void. There's no amount of reasonable curating effort that will save a news feed like that.

I try not to be too negative about things but without some serious change I'll use a static LinkedIn profile and visit it for a fraction of a second every week - to check for messages - and nothing more.
Its very difficult to get any type of semi-permanent/permanent work visa for foreigners in China. A lot of foreigners who go to Shenzhen to work on a hardware start-up, are doing it illegally in technical terms. They are all on business visas on which you can't start a business in China. And beyond just work, civil liberties are extremely limited in China. You are good as long as you don't get the government looking at you.

If you read the entirety of my post, you may notice that I did not label the United States as a xenophobic country.

Great question. Beyond being on the cloud and everything that goes with that, I'd say that there are two fundamental differences with a product like SSIS.

1. Dataform focuses on transformations happening _inside_ the cloud data warehouse. We don't move data between systems. More and more businesses are moving from traditional ETL processes to ELT and centralising their raw data in their warehouse. Dataform help businesses manage the T in ELT.

2. Dataform is built with software engineering best practices in mind. In Dataform, all your transformations are written in code (mostly SQL) instead of a GUI like SSIS. The code can be version controlled, edited and fits better the large amount of transformations teams have to deal with.
I'm sure there are, that's where a lot of small non-profits find their leaders and board members, but past a certain size, the amount of time required means that they would not be retired anymore, and I presume most of them retired because they had interests to pursue beyond managing large organizations.
> calling efforts to fight cheating "evil" is silly

their method (blocking Wine) is questionable though. it reminds me of websites that block Central/Eastern European IP's "because of bots" (yeah, it happens). the goal is nice, but the method hurts many honest users.
Yeah, but how does running a Windows game on Linux = cheating? I understand the need for modern multiplayer games to have anticheat (however unfortunate, and I still refuse to play games that use literal rootkit-esque anticheat [1]), but just trying to run a game on Linux isn't cheating in itself. Does Wine help cheats cloak themselves?

I am not even that good of a programmer and I also agree with you that index relatively trivial.
Other major issues, besides fighting spam:

- Hardware infrastructure and data center presence for extremely fast search from anywhere in the world.
- Near real-time search suggestion.
- personalized search results based on past search + geolocation.
- Search to get instant results without having to go to a website.

Just to name a few. Google Search is the gold standard of a search engine, not because its Google or because they have been around for a long time and the brand name sticks (I am sure it helps too), but for the simple fact is no search engine is even remotely close to being as good as google and I have tried them all more of the less and given them shot. They are just not good at all.

I also don't understand the hate towards google being in charge of so many products so many people use, ie, Mail, Maps, Chrome, Android, Docs (to name a few). It's simply because they are damn good at it. If its a crime to make a product so good that people continue to use it, then I don't know what else people are supposed to do. As if we are asking google to make shit products, I just don't understand the reasoning.

Good, next time I’m fishing and get approached by the DNR I’ll be sure to thank them.

Fishing is weird in some ways. My trout stamp directly funds the stocking and protection of trout waters in Georgia. The parking passes I use for fishing and kayaking locally directly fund those parks and rivers. The same in Florida, my saltwater license is funding the restocking of Redfish and other species that were wiped out by Red Tide and hurricanes last year.

For hunting and fishing you have a vested interest in the wildlife. I’ve seen hunters on TV call the DNR on themselves because they are that dedicated to the outdoors.
That's curious. In many country, food banks plainly tell you they don't purchase food. Their claims is that this way they get leftovers from supermarkets and such, who would otherwise think of selling it to them, and that they don't want to focus on raising money over wasting less food.

Fixing Smeaton’s constant was only small part of the puzzle. They discovered in wind tunnel that certain shapes produces almost 3X better lift to drag. They tried out 150 shapes varying one variable at a time to find optimal shape and angle of attack [1]. Another big problem was 3 axis control system and designing propellers that can generate enough thrust. Before Wrights, propellers were used in ships but no one really understood how the worked and their design was largely “cut and try”. Wrights needed to produce enough thrust to lift whole machine with just ~10HP engine. They literally invented theory of propellers as wings and deviced equations to compute thrust. They also designed mechanism to transfer power from engine to propellers and the fact that they need two propellers rotating in opposite directions [2].

Take these results with a grain of salt. There's a large class imbalance in this dataset and ROC curves can be misleading in this case. The test set contains 269 positive examples and 8482 negative examples.

From [1]:

> Class imbalance can cause ROC curves to be poor visualiza-
tions of classifier performance. For instance, if only 5 out of 100
individuals have the disease, then we would expect the five posi-
tive cases to have scores close to the top of our list. If our classifier
generates scores that rank these 5 cases as uniformly distributed
in the top 15, the ROC graph will look good (Fig. 4a). However,
if we had used a threshold such that the top 15 were predicted to
be true, 10 of them would be FPs, which is not reflected in the
ROC curve. This poor performance is reflected in the PR curve,
however.

The authors seem to be aware of this in the supplement and also evaluate performance by a hazard ratio they define:

> We calculated the ratio of the observed cancer incidence in the top 10% of patients over the incidence in the middle 80% and referred to this metric as the top decile hazard ratio. We calculated the ratio of the observed cancer incidence in the bottom 10% of patients over the incidence in the middle 80% and referred to this metric as the bottom decile hazard ratio.

However, binning is a form of p-hacking [2]. And I'm still wondering why they don't just post the Precision-Recall curves.
