I'm not even sure multiple inputs are all that desirable at this point. Better to just get a nice AV receiver unit that can handle all that for you and has the interface stuff you want.

Of course, the same argument applies to this as to the smart TV features— if the cost to include extra ports is small and many people still use them, it's easier for the manufacturer to just include them everywhere than maintain a product variant.
My cable box has a remote that's able to turn off and on my TV and switch the TV's sources. I haven't taken the TV's remote out of its original packaging.

It's 2019 - this is a solution in search of a problem.
Let's run the numbers... a typical container cargo ship might be say 20,000 TEU and use apx 300 tons of fuel per day. With trans-pacific voyage of 12,000km at 20 o 24 knots (apx 40kph), we're looking at voyage times of 12.5 days -- let's add a bit of slop and say 15 days. This totals to 300 * 15 = 4500 tons of fuel, or @ $550/ton => $2,475,000k for fuel costs. So more like $2.5mil per voyage (not $250k).

20,000 TEU's (or apx 10,000 "large" containers as hauled by a truck or train car). At apx 15 tons per container, that's 150,000 tons of cargo. So cargo ships use apx 30kg of fuel per ton of cargo (or $16.50 per ton of cargo).

So how much fuel used is to move 1kg of cargo across the Pacific ocean (12,000 km) by ship? It works out to be about 30cc (1 fluid ounces or 2 tablespoons) or $0.0165 (or €0.015) of fuel to transport 1 kg of cargo across the pacific. An iphone (box and all) weighs just 200g, so it would cost 1/3rd of a penny of fuel to move across the pacific by ship (about a teaspoon).

That seems pretty damn efficient to me. I suspect that many people don't realize just how freaking massive modern cargo ships are. To put it into perspective, they are often bigger than the largest modern aircraft carriers and multiple times larger than WW2 era aircraft carriers/battleships.

> And what if the cryptographic hashes are broken, stolen, or whatever?

You've still improved the scope of exploitation from:

- Need an RCE (remote code execution) in any service on the device for a persistent threat

To:

- You need an RCE in any service on the device

- You also need to be able to generate a cryptographically signed update which will install for persistent threat

That's a win. That's a BIG win. Particularly as regular updates can replace compromised cryptographic credentials.

You're essentially arguing the "if the solution is imperfect, we should do nothing" fallacy. You haven't proposed a better alternative, just argued that no action is better than an action that falls below perfection.

> If you want to stream, the apps need to be updated as streaming service providers update their systems from time to time.

Which may require a reboot. It is unfortunate, but makes the device more secure and less susceptible to hardware originated data corruption (since the volumes can be completely verified for correctness, compared to the source images which can also be verified for correctness via HMAC).

There's no specific set standard for how bin updates work. They can range from complete file system updates to incremental updates.
Germany is interesting - they have a nationwide bottle return system. Every supermarket over a certain size is required to have a bottle return system in place, and compensate you accordingly. It's called the "pfand" (deposit) system.

I'm not saying we don't pay for it, but discouraging consumption by taxing usage directly at the pump or indirectly at the drill will end up doing more harm than good for our economy.
You said one day of GPS is 0.005% of one year GDP, but we're comparing a day of GPS to a day of GDP, so it seems proper to say it's 1.8% like your earlier quote, right? If we lost any length of time of GPS, it would be 1.8% of that period's GDP?

> You can't just copy the Markdown (or whatever format your wiki uses)? Most of them read fine as plain text.

In the process you will lose links, images, etc. Additional complication is, if these are multiple wiki pages, you have to save each separately.

You are not going to explain that to normal users. (Ever explained to a user, why he cannot attach word documents into bug tracker, but he is supposed to put the content of the document right into the appropriate text fields? Not fun).

> You don't need a server to use SQL (see: SQLite, H2, Derby, or even Access).

The reason why Access is not being used is, that it is not a part of the most sold Office SKUs (neither SoHo nor Pro). In fact, I just tried to quickly find out, which are the the non-365 SKUs that do include Access, and I failed.

And again, normal users are not going to use sqlite, h2 or derby without having some kind of forms frontend. Access would be ok, but it is not accessible to everyone who has Excel anyway.
Hygiene? You can safely clean glassware with the most aggressive of chemicals, then maybe run it through an autoclave for extra safety.

Stocks and cryptocurrency are not at all the same thing, I assume people think this way only because they can both be summarized as a number that moves up and down over time. Apple is a company located in the physical world that owns raw materials and a business process that transforms raw materials into value. It makes no sense to have another Apple ticker because the point of a stock is to track the value of that physical company. Cryptocurrency is totally different in the sense that it isn't a thing that exists in the physical world, instead it is a collective abstraction over a distributed database that the users agree to call "bitcoin". It is a purely political designation.

From your story, I'm not even convinced your dad was in the wrong here.

I try to use PS4 Pro as my "smart TV", but I end up having to use the TV itself (which runs Roku) sometimes because of its larger app base. You can't watch Starz through PS4. You can watch Amazon Prime, but not in 4k.
The problem with glass is that it isn’t biodegradable. If it gets broken, it can cause a hazard for humans and wildlife. If it gets thrown away, it’s not going to break down. Glass is good for the ideal case, but not great for the other use cases. For milk and juice, it’s seems like thick paper might be a better option, since it’s biodegradable and recyclable.

It doesn't matter to the end user! If you have a bug in your code that can be detected by a new compiler warning, that's cool, but it shouldn't prevent your users from building their own version of your project.
>SQL isn't hierarchical enough. Everyone who has tried to interpret a join result has experienced this: the DB is trying to pack a tree into a table and something is lost in translation.

Can you expand on this? I'm not sure I follow.

The only dataset that I have worked with where SQL limitations hit hard and fast was a 3D fMRI timeseries dataset, the type of data which isn't meant to be queried using SQL in the first place. Sure there's also certain graph-based datasets which you wouldn't want to use SQL but this is by far the exception and not the rule. You'd be surprised how many datasets can easily be ETL'ed and stored relationally, and even nested tree structures are generally nothing a few SQL views can't fix.

As for your "affects performance" claim - this has been made efficient for DBs like Redshift with compound/interleaved SORTKEYs and all/key DISTKEYs. And other modern warehouses like BigQuery, Snowflake, etc have their own solutions.

I think SQL is just hierarchical enough, not unlike the porridge in the Goldilocks fairy tale.
“On the afternoon of last January 15, a flock of Canada geese flew about 3,000 feet above the Bronx in a loose echelon formation, tending to their own business as usual, with nothing special in mind. Much about those particular geese will never be known—for instance, where they came from, and where they were headed, and why—but it is likely that they were large, well fed, and self-satisfied. Evidently they were also fairly dumb. Their stupidity cannot be held against them, since they were just birds, after all, but geese are said to be adaptive creatures, and it is hard not to think that they should have had better sense than to go wandering through New York City’s skies”

One consequence is having your accounts compromised if you choose to login to Netflix, YouTube, etc on the device. That could be especially problematic if there are marketplaces involved, such as on-demand video (scams like this where the attackers operate a selling account https://www.denverpost.com/2017/04/10/amazon-third-party-sel...)
I was thinking more along the lines of manufacturer's warranties, which are often hard to actually use. Or Teslas being in the shop for weeks due to an unavailable part.

Customer service has more to do with company-specific culture than what you actually paid. There are good and bad examples in every industry (or even with the same company).

I had a Roku 3, which was nice when I got it. Then they started patching ads in everywhere. I've since chucked it and sworn off the company.

Apple TV is the only "smart TV" device that I'd trust to not patch in ads like that at this point.

Similarly, it's the only one I trust to not be spying on me for data brokers.
Why would you have a scan-based security approach? Why not just enforce code-signing of all executables like on iOS? It shouldn't be too hard for a closed, embedded platform.
You can grab build artifacts from builds of the master branch off their CI. You need to enable developer mode to allow the loading of an unsigned binary.

It's an interesting idea, but you still have single threaded rendering in the end with OpenGL. However, you are able to keep that thread constantly busy which is a big plus.
I managed to get a dumb TCL off Amazon in December 2018. I think you might still be able to get one. It was the 2017 model. The TV is fine enough. The display ghosts if you're playing any quick video games though. It's not the worst ghosting I've seen, but it's not great.
Something important to note when reading this is that at a university in the US, almost everyone is a professor. That's why these pay ranges are so wide - they include both very junior part-time staff and very senior world-class full-time staff.

Anything is Possible with Bitcoin ᵗᵐ

Except something as simple as increasing the block size to allow Bitcoin to process more than 7 transactions a second (Visa handles 42,000 tx/s comparatively). Theoretically it is possible, but the way Bitcoin is designed puts changes in control of people who stand to profit from preventing certain changes (i.e. Tragedy of the commons) like block size increases - and they are blocking it. The point is that Bitcoin isn't some piece of software that you can magically push any necessary changes to.
> Are knobs and plastic moldings that expensive though?

If you consider the entire cost, yes. Every BOM item has a huge cost associated with it, and it's price only a small fraction.

Consider that for every item you need to:

* secure supply for the next 10 years or so

* organize purchasing and put it into the supply chain

* design assembly instructions, teach workers how to assemble it

* design and implement testing procedures

* design and implement diagnostics to figure out which specific component has failed

* maintain it and keep it available for your service network for the next 10-15 years

* deal with unexpected failure rates and be ready to re-design in case of problems

* also, every knob is actually not one component, because it needs to be connected to something, which implies wires and connectors (the most problematic components in electronics) and multiples all of the above several times.

Look at it this way and suddenly you really want to minimize the number of individual components and replace them all with a single touchscreen. Especially given that you can then deliver crappy software and the market will bear it, because we have been trained to expect and accept crappy software.

But I do agree that the marketing appeal is there, too, although I think some people are waking up.
My understanding is that it isn't so much "VMware doesn't support Hyper-V" but that "Hyper-V doesn't permit other virtualization platforms to run alongside it" and that may be less of a technical limitation than one might assume.

The first example is used to explain what a tensor product of 2 graphs is.

The second example was used to show how colouring the tensor product may actually be useful.

I thought the second example was a little more complex (primarily because it requires the connection of incompatible nodes, as opposed to the more straightforward pairing of compatible nodes), so having a different, more straight forward example to just explain tensor products was helpful.

Also, having 2 different unrelated examples for the same thing can definitely help with understanding the underlying property/theorem.

Not a very useful analysis, there are various levels of pay-grade and they all except the lowest ranks, often have 'professor' in their job titles. eg. Associate Professor, Assistant Professor, Professor, Professor Emeritus, Visiting Professor, and sometimes Contract Professor.
I don't think it's really about the data collection or whatever. The problem is that today, right now, you will get a much better experience with a dumb TV and a smart appliance than a smart TV.

Like the software quality is better, you can mix and match devices, you get feature and security updates, the apps are better, you get support, the apps don't EOL when next year's model comes out.

I don't really care if TV's bundle their software stack into the device -- clearly some people like them. It's the TVs that put ads on the input selection menu that go straight to my shitlist.
You can get some way there with a proof of the five-color theorem, though, which is much simpler.

So what is this memory wall?

> this concept revolves around the idea that computer processing units (CPUs) are advancing at a fast enough pace that will leave memory (RAM) stagnant

> According to Moore’s Law, which states that the number of transistors in a circuit doubles every two years, CPUs will eventually become too fast to yield any noticeable difference in computing speed. Once we reach this so-called memory wall, program/app execution time will depend almost entirely on the speed at which RAM can send data to the CPU. So even if you have an incredibly fast processor in your computer, it’s function may be limited to the speed of your RAM.

Oh, it's utter nonsense.

For one, it's ignoring that the cache speeds scale right along with the CPU. You could get rid of DRAM entirely to prove there is no 'wall'.

But what really kills the argument is a proper analysis of how memory is set up. Internal to the RAM chip, there's a ridiculous amount of bandwidth. The bottleneck is using a 64-bit-wide bus to communicate with the CPU. But that bottleneck is only a cost saving measure on top of Moore's Law. If we back off to pure Moore's Law, we can quite easily add more and more memory width/channels and not hit any limits.
Yeah, that's why the reboot is required, it's like changing kernels on linux. I think they are moving to have it on by default, and eventually they may just make it permanently part of the OS install. Kind of like how they take control of the TPM on install even if you don't setup BitLocker, I imagine they will just have the core hypervisor permanently enabled and then it's up to the user setting what actually uses its features.

KeePass. It's on every platform and is free.
Intel's PEXT and PDEP instructions are the #1 innovation to bit-manipulations. Its basically bitwise gather / bitwise scatter, some of the most flexible operations I've ever used personally.

Popcount is... ridiculously standard. Even GPUs offer 64-bit popcount. Bit-reversal is surprisingly useful in my experience as well (ARM and GPUs offer single-cycle bit-reversal). So I'm surprised to hear that RISC-V doesn't have popcount standard.

Bit-reversal is great because adder-circuits carry only goes in one direction. So all of the "least-significant set bit" tricks that are done can be inverted into "most-significant set bit" rather easily with just a bit-reversal. x86 is missing out on bit-reverse, while all other platforms (GPUs, ARM, and Power9) seem to have it.

I'm also of the opinion that multiply-xor-bitreversal-multiply is a very powerful hashing tool (multiplication by odd numbers is 1-to-1 bijective, xor is 1-to-1 bijective, bitreversal is 1-to-1-bijective... so a multiply-xor-bitreverse-multiply cycle can transform any number into a singular 'random' number across all 64-bits space). x86-fans don't get bit-reversal, but bswap can be used to largely the same effect for hashing.
The move to single-stream recycling probably represents the single largest setback in the U.S. to the cause of waste reduction.
