I dunno... I recall loading stuff off cassette tapes onto C64.

But I was there in the 90s, too.

Sure, the load times on an NES are better than, say Fallout 4, but I remember starting up Ultima 8 for the first time and that was some sincere amount of wait.

I think that things are much better now, at least in the few games I've played in the last couple of years (Bioshock, Detroit: Become Human, Fallout 4, Red Dead II). The content is way more developed, and instead of loading a pile of floppies, I just wait for it to DL what it has to do. Granted that takes a while, but at least I don't have to hand feed it.
Maybe slightly off-topic but I've always struggled to understand the appeal of key-value stores like Redis and DynamoDB. I tried using it once as a substitute for shared memory in an embedded device, but you lose a lot of information (like type) and it seems like you can't represent or query complex data structures like nested structs without serializing it out to some data format first and then storing that in in the store (but at that point it's starting to get slow/complex and you can't easily examine what's in the database and so it's easier to keep using shared memory).

But clearly I'm missing something because everybody loves them and uses them. Is this a technology I would only use when building websites at scale or something?
It won't be much different than what the current generation storage devices contain.

You already need to upgrade SSD firmware these days. Linux fwupmgr has support for few of them.
There is already a computer in the SSD, replete with DRAM, multcore CPU, custom math acceleration (depending on SSD design and vendor), etc.
I see these as pointless technology because you still have to deal with data protection explicitly at a higher level. Given that, what does KV per drive really get me?

It's true not all websites depend on ad revenue, however, there are other problems with Google's Knowledge Graph: Others can tamper with it. There are numerous stories about malicious edits to Google's Places data to redirect calls from legitimate businesses, or mark businesses that are open as permanently closed.

While a business can control the information on it's website, it can't control the information on Google's, and often that is not to consumers' benefit.
After 1989 it took the Nikkei more than a decade to finds its bottom (and then another bottom in 2009) and it hasn't recovered since. How many years of "discount buying" are you planning in?
This case is another example of sensationalism. The teenager has a rare and unusual case of malnutrition. He's gone blind by pure chance and circumstance; there are other possible outcomes. It's the fact that he's gone blind from eating junk food that the media obviously monetizes. Other cases with different outcomes do not sound just as interesting.

I know at least one person who avoids vegetables because of a phobia/aversion. And, I know from personal experience that actually healthy nutrition can be really costly depending on where one lives. I also know from personal experience that malnutrition in itself is as common as the common cold.

That sounds perfectly reasonable to me, but John Hennessy literally wrote the book on computer architecture. Towards the end of the deck he has a slide that we shouldn't expect large gains from improved architecture (on general purpose chips) in the future. I'm inclined to believe him, although I would be interested in hearing a deeper proof/disproof of the architecture you proposed.
I think if you can make your model work with a competitive APR then you'll take over the world. At 20% APR I would guess it's just not worth it for the majority of businesses (ourselves included).
Adding more dedicated hardware that does what you can do on the hardware you already have is not necessarily an advantage.
This has been the case for a while already. Even spinning-platter hard disks had some reasonably powerful CPUs to implement caching, bad-block remapping, and SMART data retention (among other features); SSDs pushed this to another level by demanding higher performance and more complex remapping.

Chances are that this Samsung device isn't even using different hardware from their standard SSDs -- just different firmware.

This is a sort of punctuated optimization that is natural in any technology.

When a fundamental technology is evolving rapidly, not much effort is put into optimization. It instead goes into keeping the momentum of evolving the fundamental technology.

When it hits a physical limitation, everyone scrambles to now optimize.

Until the next generation of fundamental tech shows up and evolves rapidly again.

Think about air travel and how every airline is now all about fuel efficiency.

A single new technology eg: a new battery chemistry that is say, 2x as energy dense as the best right, now comes along, electric air propulsion will become a major thing. And airlines will be scrambling to offer faster, quieter options that may not necessarily be the most efficient.

If we are going to go by what the people thought, the people didn't think they were going to get a no-deal Brexit. Leave told a whole bunch of lies. Now that the reality of no-deal Brexit has set in, the position has proven unpopular.

All I am saying is that now that we know that is the reality on offer, that the British people should get to vote on it. Since no-deal Brexit will lose at the ballot box, I can understand why its supporters want to avoid such a vote.
I had a chance to see Judea Pearl speak at a high-end mathematics conference a few years ago, and asked him personally afterwards about a few things in his talk.. I did not get much satisfaction in the admittedly brief exchange, and therefore unfortunately my impression was that there was some smoke-and-mirrors aspect to his talk, I would guess for some competitive reasons I don't know.. however, the company on stage at that event were of the highest rigor, so take this as you will...

Stack Exchange as one example aggressively uses Redis as a caching layer for practically its entire service.

Redis is very fast, dependable and relatively easy to use. The alternative, other than a competing product, is pretty much that you have to write your own custom replacement Redis in some manner. That might be fine at a small scale for fun or in an experimental product that isn't meant to go into production; otherwise you want something well proven, that many other engineers you can hire are likely to have experience with (it's hard to over-emphasize that last point).

This is not an accident, but a causal relationship - the increaseing desire to "to hold on tighter to their already disappearing lifestyle" is a factor that's likely to drive the people even more towards populistic leaders like the worst cases in multiple countries now, or "strongman" fascist-like parties.

As the effects of climate change become apparent and causes economic strain either due to attempts to prevent climate change or the consequences of not preventing it, well, in times like these that's the exact type of team that people will vote for.

And even more, as the global 'tragedy of commons' scenario of splitting the burden of mitigating climate change becomes even harsher, and the very unequal burden of consequences of climate change strains relationships, we should expect that agressive nationalistic movements will become even more popular both in developed and developing countries. In short, we'll have a situation that has many parallels with the worst aspects of the 1930s and the type of autocratic leaders that people in so many countries worldwide chose back then.
The entire toolchain is non-deterministic. People also do stuff to make it worse.

For example the compiler backend is multi-threaded and spits out data in whatever order, doesn't matter normally because they designed it that way.

But in a determinstic scenario you have to change that.

Then you have to worry about timestamps in PE headers, macros in code, other tools messing with things, etc...

Then you have the issues of wanting to cache, that's where things like pathing come in to play.

Usury laws typically apply to consumers, not loans to businesses. They also probably wouldn't count this type of financing as a loan. Regardless, this exact method of financing already exists and is very popular so I'm going to go on a limb and say that it's legal.

Pictorial View to Easily Understand Async/Await in Node.js
I think it's happening somewhat in the software space, where we pursue speed improvements by penetrating through sometimes literally decades of accumulated cruft layers to build something more modern. It is ironically harder precisely because it's easier; we've got a lot more software layers because it's so much easier to add another one. Wayland is probably one big example of it, but I often have this feeling in my Go code, too, where instead of a framework on top of a framework on top of a very framework-y core language like Python, we more-or-less just get on with it, both at the level of the code I type, and in the generated assembler as well. I imagine Rust programming feels much the same way when working with Rust-native libraries, I just don't have direct experience.

It's not all Electron apps out there.

Also, when I call something "accumulated cruft", it's not just vague "bloat" concerns I'm referring to; you have the problems of several layers of leaky abstractions, and those leaky abstractions may well date from an era of radically different hardware. It's true this can cause "bloat", but it causes other problems, too.

Nobody wants to deal with raw flash. It's awful.

The error rate of raw flash is incredibly high -- it takes loads of error correction to make it reliable, especially with modern MLC and QLC memories -- and the structure of flash erase blocks means that it doesn't support random-access writes. A proper flash translation layer, implemented in hardware, means that software can forget about all the strange features of flash and use it as general-purpose block storage.

The "Aware Home" as imagined as a closed-loop system would be so cool, but I imagine it would be hard to actually secure anything like that successfully as a system owner. It seems like we have gotten to the point where all security is traded for privacy, in that an individual believes that it's too hard to manage tech that would keep their systems secure, so they give corporations the job, in exchange for at least their personal privacy.
Stegasuras: Neural Linguistic Steganography
Essentially, all vessels over a certain tonnage are required to broadcast identification data (AIS) for safety regulation so other vessels can identify them. Many companies now exist that listen in on those public vessel broadcasts and aggregate the date. Messages are sent by the vessels constantly, and terrestrial antenna are installed by companies, or assisted by volunteer hosts to help collect the messages along coastlines. Satellite companies can aggregate as well, but are usually hindered by how often the pass over a certain area (10 minutes of visibility every 90 minutes, depending on the constellation, and the company).

All in, the larger AIS data aggregators collect about 500 million messages a day from around 150,000 vessels through terrestrial and satellite sources. Access to the full feed, with no delay, is sold for up to $500k/year, though typical deal sizes are around $75k/year. Access to online map-based products usually cost around $10k/year.

>> but that battery in South Australia is only 100MW and the grid lost over 1400 MW

>I hear this kind of misconception fairly often and so it is worth noting that you don't need 1400 MW of battery to protect from this event.

I would be interested in any papers or literature that have led you to this conclusion.

as soon as (generation - load) <> 0 the frequency is going to change. If you lose 200MW of generation and have 100MW of batteries that are configured with 0 or very small amount of droop they see some small change in frequency and crank out 100MW to try and stop it from falling further. Then they are maxed out, there is still 100MW of imbalance for conventional generation with governors to take up, which they will as the frequency falls as if the trip had only been 100MW in the first place. How is this not a 1:1 relationship, 100 MW of batteries displace 100MW of lost generation?

For this event in the UK in particular it appears the issue is that the large windfarm, and 500MW of small embedded or distributed generation are en masse improperly configured or by nature are not able to ride through any small transient wobble in frequency. TFA didn't show us what voltage these plants saw.

Although a 200MW steam turbine also tripped due to the same lightning/transmission line trip event, so clearly it was subjected to something that exceeded instantaneous thresholds and had to trip immediately. And then that steam turbine tripping caused the gas turbines at the same plant to trip which indicates there are some design or operational issues at that plant.

Also is 20s reclose time for a transmission line standard? I've only configured distribution line reclosers but it was more on the order of 1s for the first reclose and maybe 7s for the second?

The interface is for random access. Quite a few database optimizations depend on sequential access, I.e. accessing records in key order following a random access. This is why B-trees are so important. Sequential access in key order does not appear to be a possibility with this technology.

On Apple's platforms, Instruments has a memory allocation logging tool that's very nice to use. Just attach to a program, no need to recompile:

As a nice bonus, it can also look for memory leaks by running what is essentially a conservative garbage collector on your heap and reporting unreachable allocations.

The problem is WeWork would end up being just one of a ton of possible vendors who do this. The only thing that's hard to replicate about that business model is the up-front cost of acquiring the properties, but if it turns out to be a thing people value then CBRE and every other big commercial real estate company will dive in. In that environment where your IBMs now have competing products to choose from I don't see WeWork able to pull much in the way of margins.
