I think to some extent the boundary of friction that's going to grow between software creators and hardware manufacturers as various shapes of Smart-thing-X become more prevalent might ebb this a bit.

Because as more feature-laiden software is written to facilitate growth in consumer and industrial markets that is deployed on something more akin to an embedded device than a PC or server there's going to have to be more rigor applied to the correctness of the software to compensate for how tightly coupled it is to the largely immutable use-specific hardware.
Holy crap is this thing for real? Sorry but this is straight up inefficiency in its finest. Honestly the amount material to produce one farm bot far out weighs the amount of produce in can produce. Like I hate monoculture farming but a 20 Ton tractor can service like 10 Thousand acres of dry area/irrigated cropping country a piece of piss, do it automated and by GPS and return Hundreds of Tons of produce.

TBH if someone would just build me a robot that has 20 km range, can deal with crawling up hills and can identify coloured shapes and "pick" them (pneumatic suction would probably do it), We could put a few tens of thousand blueberry/coffee pickers out of business.

FarmBot will not put anyone out of business. The Japanese Aeroponic farms have a better chance of being the future of production.

>Yes, if you've programmed the scenario in.

Explicitly programming scenarios in is not how it really works.

>How much of it have we mapped, and how well does the machine cover it?

Enough for Google cars for example to have logged over 300K miles in actual conditions with no incidents.

Also enough to have such things (besides Google's) in pilot operation in several cities the world other, for things ranging from cargo transport to mass transportation (self-driving busses).

It's not like "programming the scenario in" is some huge switch/case statement that needs to cover all possible arrangements of things on the street -- it's machine learning algorithms with several rules and invariants to check and various corrective responses when those are off, and the smartness comes from the combinations of such rules.

>machines will remain shitty drivers because they can't respond with creative judgment to a new situation.

The think is, with the appropriate machine learning algorithms they can both add experience and respond with creative judgement to new situations -- they don't have to have hardcoded responses to them from the start.

It's fast because it doesn't actually save your data when you ask it to. It saves it later, when it feels like it, maybe. Also, the hate I have for Mongo is from first-hand experience with the wretched thing. The scaling is insane. The next jump after your first server is like 9 servers (2 repsets w/ 3 servers each w/ 3 config nodes). I don't have that kind of cash laying around for servers, especially when instance-for-instance, Postgres can handle easily 10x the write load of mongo.

You are correct. VIP might be not the right word but there could be better wording than the official "surge pricing". If you are charging someone 25% more clearly tell why and what the user is getting more than those who are not willing to pay 25% extra.

Or simply don't tell anything about increased prices. Just show the estimated price and let the user decide if he wants it or not.

In fact you can on-board the user into app to simply be blind to price increases up-to 75% or something.

This thing might be cost-effective if it were scaled up to round farm size. A standard center-pivot irrigator is 400 meters long.

I also think most robots would pass the "I couldn't tell its a robot" test with flying colors if they responded just like real people in the same settings as everyday conversations -- because those interactions are usually limited in scope, and you don't purposefully try to unmask those people with tricky questions.

Somehow about a month ago r/powershell convinced me that I needed to give VS code a look. There aren't any free / cheap multi-purpose editors that handle Powershell IntelliSense worth a damn, so given all the effort Microsoft has been putting into the Poshtools extension for Visual Studio I figured maybe we'd see something good in VS Code.

I was horribly wrong. It is so comically bad at Powershell that I took screenshots. It has some coloring... and everything else it's doing is broken.

Makes me wonder why VS Code even exists. There is no shortage of first-class editors for every other language that VS Code supports. The one language with a genuine need for a great new editor, a language from Microsoft no less, is supported in a manner that doesn't even rise to the level of half-assed.

Well then you should read a little up on it.

The president will need permission to declare war.

Trump can in theory command the nukes to be fired without declaring war but this only works if there isn't any political opposition agains his case (i.e. it would be considered unpatriotic to disagree with his decision)

Given the general dislike for Trump there will be plenty of dissent if he decided to just send nuclear bombs left and right. The military would overthrow him pretty quickly.

So yes there are checks and balances and in the case of Trump they would make sure that he followed protocol.

You dislike him so your analysis of why he would be thin skinned has little value here too.

It is correctly called Scots. Scots is as old as English. It is just as much its own root British language though often misconceived as a dialect of English.

Scots has its own dialects like Dundonian Doric.

The other Scottish tongue, the language of the Highlands and Islands, is Gaelic - a Celtic kin of Irish.

Scots is Grammatically Distinct, e.g. the 2nd person plural: yous (the plural of you): as in 'yous are all dafties'.

Some American derives from a Scots root rather than English, e.g. the poke of chips of Appalacia is Scots.

> Because some people can't stand having to work with SQL,migrations,schema and constraints

The thing is, if you actually try and write an app using MongoDB, you will rapidly find that you:

1) Have migrations (except they're going to be some scary ad hoc nodejs script that loop through your document store and modify fields on the fly).

2) Have schemas (except they'll be implicit and undocumented)

3) Constraints (except they'll be hidden inside your app logic, and violating them will cause data corruption).

The biggest lie about NoSQL databases is that they're schemaless. If you're EVER going to read the data back and do anything with it, it has a schema.

For businesses? Sure there's gonna be a lot of limits. Only 7 billion humans so that sorta limits any user tables. Only so many things those people can buy each day, so that limits your orders table.

VISA does what, 150M transactions per day? I was doing more volume than that for telephone calls a couple years ago with a $5K server and a default install of MSSQL. (Full ACID, updating balances -- yes I know a CC tx is probably heavier than a VoIP call but still.) At 4KB per tx, VISA could use VoltDB and store all tx's in RAM for a week for like a million or two.

An 150M a day today is not that much more than it was 15 years ago it seems. (50-100% more?).

For many, many, businesses, data size just isn't an issue any more cost wise, and soon won't be a technical challenge at all either. Yet 10, 20 years ago, we're talking 8-digit+ implementations.

Sure there's some things that grow faster, like all this increased tracking. But in general?

Yes, I don't disagree with what you've just said. But as I've been saying there is more to freedom of speech than what is possible to guarantee legally.

In this case, my statement is meant to encourage people to seek out Freer software.
2,000 cycles sounds great, but at just once per day that's only 5.5 years. Grid storage needs to be really cheap AND last for 20-50 years. Which is why capacitors and pumped hydro are both used. Capacitors can discharge 1,000's of times a day to maintain the proper wave form and hydro can discharge 1-3 times a day to handle changing demand.

PS: The real advantage of hydro is you can invest in capacity or peak load as more or less separate things.

I don't know why you're getting down voted either. will the down voters please address the following concerns?

1. Considering that some of the apartment dwellers will become homeowners and their place will be taken by new apartment dwellers, how will the overcrowded schools support the influx?

2. Considering people will take public transit to go to work, they still would use cars to move around locally in the area on evenings and weekends. How will the current streets support the greater density of cars? e.g. Central Expressway used to be an expressway now it is a parking lot.

3. Overburdened police and firemen will be exposed to further strain.

4. Parking is a nightmare not just on residential streets but even at local establishments. Space needed for parking is used to build more housing.

Unless you live here and face these issues it's easy to downvote rather than come up with solutions that are at pace with the housing construction boom.

Everytime I hear arguments for going back to relational databases, I remember all the scalability problems I lived through for 15 years in relational hell before switching to Mongo.

The thing about relational databases is that they do everything for you. You just lay the schema out (with ancient E-R tools maybe) load your relational data, write the queries, indexes, that's it.

The problem was scalability, or any tough performance situation really. That's when you realized RDBMSs were huge lock-ins, in the sense that they would require an enormous amount of time to figure out how to optimize queries and db parameters so that they could do that magic outer join for you. I remember queries that would take 10x more time to finish just by changing the order of tables in a FROM. I recall spending days trying different Oracle hints just to see if that would make any difference. And the SQL-way, with PK constraints and things like triggers, just made matters worse by claiming the database was actually responsible for maintaining data consistency. SQL, with its naturalish language syntax, was designed so that businessman could inquire the database directly about their business, but somehow that became a programming interface, and finally things like ORMs where invented that actually translated code into English so that a query compiler could translate that back into code. Insane!

Mongo, like most NoSQL, forces you to denormalize and do data consistency in your code, moving data logic into solid models that are tested and versioned from day one. That's the way it's supposed to be done, it sorta screams take control over your data goddammit. So, yes, there's a long way to go with Mongo or any generalistic NoSQL database really, but RDBMS seems a step back even if your data is purely relational.
Actually, wealth inequality in the West was higher before World War One. They called it the 'gilded age' for a reason.

It only got a lot more equal because WW1, the Depression, and WW2 combined destroyed most of the stuff the rich people had.

Only recently has wealth inequality re-approached pre-WW1 levels.

The numbers are one search away. In fact even without the numbers intuition should be sufficient to see that it makes sense. Auto industry accounts for 20% of total Li batteries. Where as consumer electronics (which is probably growing way faster than electric Auto) accounts for around 37%.

Most of the reports I have seen tend to estimate that Auto's share would increase upto 30% by 2020 while renewable energy storage would grow to 60%.

It is not really hard to see that real breakthroughs in mass production and lowered prices for Li batteries will come not from auto applications but from power generation sector. I do not know of any sustainably profitable power company that is operating in that area. It also probably explains why Musk is thinking of things like Solarcity and Powerwall.

hint: Search "Global Demand for Li batteries" in Google images to see various charts.

This just in - being surrounded by good influences is good for you. And vis-versa.

This isn't rocket science, of course. We've know about the important of cultural influence for a long time. There was a reason my parents cared about where I grew up, and who I hung out with.

If you grow up in a culture where people don't care about academics, where welfare and child support are acceptable forms of provision, where machismo and crime are glorified, where you are told that discrimination will prevent you from otherwise succeeding, and that your failures can be blamed on racism - no, I don't think that culture will have a good influence on you.

Yeah, I wouldn't want to be writing new Perl either. It was actually Ruby's "optimized for developer happiness" mantra that triggered my comment.

I don't think 5% is right. You seemed to think that 30% year-over-year growth in the industry was a reasonable estimate. If it was 35GWh/year in 2013 then that puts it at about 77GWh today and 130GWh in 2018. That puts Tesla at around 10% of total production now, and 23% in 2018.

I can't figure out which part of this you object to. You seem to accept all the numbers, but continue to argue about the shape of the box they're presented in.

The stone is likely a fraud. Who would place a cryptic sign 90 feet down, telling themselves (in secret writing) to keep digging? Wouldn't they presumably know that they hadn't reached their treasure yet? Wouldn't they be more likely to place an innocuous sign on the surface, such as a gravestone? It's more likely a way to con investors out of further funds.

It's probably nothing but a rumor.
> Mongo is a dumb, dead-end platform, but they know how important ease-of-use is.

By “ease of use”, do you mean “ease of making something that seems to work” or “ease of making something that actually works”? I've never used a schema-free database, and ended up thinking to myself “I'm completely sure this database can't possibly contain garbage data”. Or do programmers simply not care about data integrity anymore?
No, I don't understand what the guy is asking, for serious. If he wanted to talk about the consequences of a tax on coal, then he wouldn't have stated his hypothetical as "absent coal."
