Blackfish was very far from being truthful. Is manipulative and perversely designed to elicit an emotional and irrational response.

Keeping whales and dolphins in a big fish tank for people to gawk it is anything but noble. People keep repeating this myth that the animals are "rescued". Some of them are bred in captivity. Do you really think it's noble to breed whales and keep them captive?
Edited to add that they also loan out animals so other institutions can breed MORE whales and dolphins to be kept in captivity. To me, that's pretty awful.

This is too extreme. It is the last frontier of some set of problems, but it just introduces a new set of problems. This always happens. Even the implausible singularity still introduces more problems to solve.

I'm surprised by the concerns over refunds. In my experience, brick-and-mortar stores that sold computer games were generally not too friendly about refunds. GameStop's website says downloadable PC purchases are not eligible for refunds at all.

I was going to say that Steam's monopoly status is overstated, since there are a few (much smaller) competitors. But in fact it looks like the games I bought on Impulse years ago have vanished; GameStop bought Impulse, rebranded it, and later shut it down. As far as I can tell, my licenses have disappeared into the ether. Motivating just about any former customers to avoid GameStop in future, I would think. Boggling.

You make a great point. To me, Google Search is a bit of a special case in that the data it provides has been posted publicly. Unless the Google Cloud ToS give them the right to publicize your business data, that's out of the question.

Another point here is that Google Search isn't an authoritative source of information, it is up to the end user to inspect the returned links and decide if they can trust that site. This is something that I would not try to automate to the point that I could ask users for money in exchange, and if it can't be automated it doesn't seem like a great fit for Google.
Well, it already works on the JVM and on Android, many production apps in the wild are already using it, and they avoided the problems that existing JVM languages like Scala and Clojure had in terms of running on Android.

A large number of ccTLDs are still run by a single random person deep in the bowels of an IT department at some university. I was just at an ICANN meeting in Madrid last week and met some of them.

Also, we (Charleston Road Registry) are definitely not a small company, but we run ~45 TLDs with a team of engineers much smaller than 45, so we have a ratio of TLDs to engineers significantly higher than 1:1.

Unlike natural gas (which we can mine from the earth), hydrogen can't be an energy source because there's no place you can mine it. It can only be a medium of transmitting energy: you need some other source of energy in order to create hydrogen, and then you can transport it somewhere else and use it there.

So the question is what is that source of energy, and whether we could simply connect the source directly to where the energy is needed and cut out the middleman H2.

I'd be willing to bet that at one point or another, Wolfram likely mentions all of these prior works. One also has to realize that Wolfram actually started thinking about this whole thing much earlier (35 years or so ago) than many of these other authors, and wrote papers about such. That isn't to say these other works aren't original, or that there wasn't art prior to even then. Finally, Wolfram throughout the book notes that his ideas aren't new or original in whole - he actually belabors on this repeatedly (so much so, it became tiring for me to read it - it seemed like it was every other page).

Nothing prevented them; Detroit automakers either had substantial interests in foreign makers selling light trucks outside North America, or were in some cases selling small pickups and vans designed by their own foreign divisions.

They simply did not feel that smaller/lighter trucks & vans would be profitable, or profitable enough. This goes off and on; often one of the Detroit makes will go years without having an entry in the small truck market.

There are advantages to using a pickup-style perimeter frame to make a van, that said, unlike Ford & Chevy, the Dodge B-series vans were unitized from the '70s on.

Other comments have already deconstructed much of the article, but I'll add this. The primary factor will be your CPU architecture. Can you put the string in the same cacheline as the code or an adjacent cacheline? If so, awesome. However, if you have a microcontroller with a harvard architecture, such as a cortex M3, it's may be better to put your strings in data memory rather than code memory. The processor can simultaneously load your string and the next instructions via the two memory ports.

IMHO, the time needed to build and deploy your own thing using open-source and open protocols is well spent when compared to being at the mercy of BigPaasCorp when it comes to stuff like this.

Where are you getting the extra 3 zeros from?

(Also 'up to 180 TFLOPs' is a bit misleading. As I read in some benchmarking posts by Google as well as by nVidida, a TPU is much faster than a GPU for doing inference, but they haven't released any data on training performance, the real bottleneck IMO).

So I left facebook 6 months ago (permadelete) and it was the best thing I did.

Unfortunatly I need a FB account to join a few groups that I am members of IRL as well as requiring a FB business account to run FB ads - you have to do it from a personal account and you are only allowed one.

I am fine with posting all my real info except I don't want to use my real surname - because if you google my full name it comes up with all the companies I own, with full financial info available to the public (I live in the UK and companies house is transparent) I have had issues with people doing this in the past and deciding they don't like me, they stuck in a 9-5 and me earning $xxx per day working 3 hours a day... etc. I would rather just avoid any conversation that involves money.

Say my name is James Bentley (it's not) should I just sign up as James B, or James Bent, (not a stretch if you are googling someone though) or James Bughey or something completely unrelated?

Thank you

There's nothing really inherent to Django that prevents it from scaling horizontally, not even the ORM. For the typical SQL read-heavy workload it will scale as well as anything else depending on the scalability of the backing RDBMS. Should always use proper HTTP response caching with something like Varnish or via 3rd-party CDN where possible.

We wouldn't "use up" water at all for this. When you burn the hydrogen (to get the energy from it), it combines with oxygen and forms water.

> It hasn't produced any fruit.

This as well is a good argument against the book. The fact that there doesn't appear to be anything brought forth in other fields, or in the same field of work as the book doesn't bode well for it.

Then again, there have been many time in history where something was written or put down, which wasn't known or seen to be relevant, workable, or whatnot, until many decades or centuries had passed. I'm not saying this book is a case of that, only that it might be. We don't really know, and can't if or until it happens, of course.
> valid question here would be - would a fresh human mind perform that well too?

I think it's questions like this that will point the way forward. Humans definitely don't come working at 100% as soon as we're born. Lots of interaction with the environment is necessary to become a functioning person. But at the same time, we still seem to have a real ability to generalize hard-wired in. A human in a small society might only speak with a few dozen individuals growing up, but they don't get confused when they meet a new person and hear a new voice.

It seems to me that lots of data will be necessary to get things off the ground --- but I think the sort of "big data" needed for this will be qualitatively different than the big datasets used to train modern state of the art models. My hunch is that it will involve an agent's interactions with its environment (so it will look something like reinforcement learning).

You can out compete Google by simply keeping your services not deprecate themselves and make them available and having good customer service . Look at Clarfai when benchmarked it against Google's API and Microsoft Clarifai was more accurate .
You mention Turing machines. One of the simple rulesets Wolfram discovered was found to be able to work as a (very very slow) Turing machine (not that a real Turing machine would be fast). I just wanted to point that out, in case you weren't aware of that part of the book.

You're right that enthusiast doesn't have any dictionary definition with the implication I mentioned. So for lack of a dictionary term, allow me an analogy that also explains why it isn't a "no true scotsman" argument.

Compare game genres to musical instruments. Guitarist == FPS gamer and Pianist == RPG gamer

Both guitarists and pianists are musicians, just like RPG players and FPS players are gamers. Feel free to expand this analogy into as many genres and musical instruments as you like.

Now take someone who isn't able to play the correct notes, cannot read sheet music/tablature/any form of music notation, has no knowledge of music theory, hasn't heard of The Beatles (or whatever cultural/genre relevant artist would be the equivalent to The Beatles), but still practices for hours every day on their 8-note plastic recorder they got in 4th grade [0]. They call themselves a musician, after all they spend so much time with their hobby!

Nobody but that person and maybe their mother - being nice - would call them a musician. Is there a hard, defined line for when they'll "become a musician"? No. There is a grey line of necessary skill/knowledge that one needs to have for others to consider them a musician. Every amateur hobby has that grey line that needs to be crossed before you'll be taken seriously.

ps. The dictionary definition of "musician" only mentions "plays an instrument" and doesn't indicate any level of skill. This is the difference between "dictionary definition" and "actual usage of a word". By the dictionary's definition our untalented individual is a musician, even if nobody else would consider them one.

> You could have a hydrogen BBQ, but the tank would probably have to be much larger for the same amount of burn time.

Isn't the opposite true? I mean, hydrogen at 700 bar has a specific energy of 142 MJ/kg while hydrocarbons in general have less than 60 MJ/kg.

When it came time for the final, it didn't come for those of us in the beta until a couple weeks later (though you could manually flash it which I did). The other was that on reboot there was a popup that you would have to hit OK on to continue.
Yeah, I agree. Makes sense for libraries. So keep that separate for library writers, don't expose me to the complexity of that.

Don't forget you can use Kotlin to write your build files for Gradle (since Gradle 3.0 was released almost a year ago) which Android Studio auto-completes 100% of the time (rather than 80% of the time as with Apache Groovy). Gradle 3.0 also switched to Kotlin as its "preferred" language for writing addins, so conceivably you could use the Kotlin language for everything in the Android build chain.

When I see anything related to splitting water into hydrogen, I'm worried that we're going to use water for energy on top of using to hydrate people.

Still today, over 10% of the world population don't have access to clean water. I'm also curious on how clean the water needs to be to be used with this catalyst. AFAIK, most catalyst conversion need pretty pure water, in which case, we would not only use water, but use _clean_ water, which is even more scare than "dirty" water...
> note that orcas are some of the most social and familial animals in the world

Humans are also some of the most social and familial animals in the world. Nevertheless, some humans kill, dismember or do the most terrible things to other humans, having so serious mental issues that must be keep apart from society. This pattern can be found in all intelligent animal species. Most specimens are fine but a few can born being psychopaths or develop as one later. And a clever psycho is not something that you should take lightly. Life is unfair, and sometimes (and I'm not saying that is necessarily the Lolita's case) there is a good reason to have a big and mean animal isolated from its congeners.

I'm not sure if it's a factor, but hydrogen gas is relatively difficult to store. It tends to seep through the walls of any container.
Okay, so you changed the DB schema in your 'dev' environment to add a column.

1. In what manner/format do you define or commit the change to VCS so it is in sync with the corresponding code change (that uses the new column)?

2. What happens when a teammate comes to deploy that schema change to production?

3. What happens when we need to roll back production to some previous commit? The need to rollback may/may-not relate to the schema change (not suggesting you 'got it wrong').

If you can answer 1, 2, 3 by some convention ... you've created a migration system that should probably be codified.
That one is awesome and inspired me to write http://www.hanshq.net/making-executables.html
> That would solve one of the primary hurdles remaining in using water to produce hydrogen, one of the most promising sources of clean energy.

What? No. Hydrogen is not a source of energy, it's a storage format. A more efficient catalyst will certainly help with losses when storing the energy, but there's no net gain.

I agree the doordash article gets some stuff right and most stuff wrong, almost to the point where it's difficult to read. But (somewhat tangentially) I admit I have struggled in the past with separating out Django apps for reasons not mentioned in the article.

Specifically, say I have two apps, with a second more specific app heavily dependent on a first more general app. What I find in this scenario is that I sometimes need hooks into the general app from the specific app, which means that I wind up importing modules from the specific app into the general app. This hasn't generally been a showstopper in my experience, but it creates some friction because:

a) I would prefer for the general app to have no dependencies on the specific app

b) This results in circular imports (which can themselves be addressed, but this is an implementation detail I would prefer not to have to worry about)

I realize these issues can be mitigated with signals, but I try to use signals sparingly for various reasons (https://code.djangoproject.com/ticket/16547#comment:2). It also helps that foreign keys can be expressed using a string literal rather than the actual model, but in the end, I still occasionally run into situations I don't feel great about.

Please note that I'm not advising against separating out functionality into apps. Instead, I'm merely citing an issue about having multiple apps that bothers me.
Wolfram noted, seemingly ad-nauseum (it felt like every other page - more often than the Mathematica plug) - how the ideas he was presenting weren't original. The sheer quantity of referenced footnotes in the back of the book, scattered all over the text, bears that out as well. Seriously - it was one thing that stood out when I read it, because I was always flipping to the back trying to read the footnotes, it became apparent that to do so was going to make reading the book take several times longer for me (I don't have that many years to dedicate to reading a book).
