Let's talk about building an app with 50 independant ScalaJs modules then and how you manage/compose them in one or many of your apps without embedding multiple times the ScalaJs runtime.

Don't forget Scala is slow to compile and ScalaJs is even slower so if you have a monolithic js app it won't scale as a good developer experience.

I'm a backend Scala developer and I'd rather use Elm than ScalaJs until it's clear how to scale ScalaJs apps.
Why Apple Assembles in China
Exactly!

This is really the biggest issue that makes the whole misconduct problem so many times worse (judging by numbers in the article, "so many" is at least around 97/3 ~= 30x, putting cases like the one in question here within a margin of statistical error -- and that is not even accounting for the fact that, as you noted, misconduct is much easier and for that reason likely to be more common in pleaded cases). And it still stays hidden in plain sight: no court proceedings to generate public interest, no doubt in public opinion, no documentaries, no nothing. And indeed very little risk in case you decide to embellish your case with a little misconduct -- after all, even if plea bargain doesn't work, you can always skip presenting the most questionable evidence at trial.

It is really quite disgusting how much discretion prosecution currently has in terms of charges to bring, and the associated range of penalties.
What's A3? I went through a phase of ordering ridiculous amounts of stuff from AliExpress (sure, I'll buy 1000 resistors for $2!), but the postage times went from ~2.5 weeks to 4+ weeks (CN->AU)
12,000 transactions per hour translates to 200 transactions per minute or 3 per second. However, you're being generous here because what you're suggesting is what it currently does at best, when in reality it is anywhere between 1 and 3 transactions per second, meaning that it is doing anything between 86,400 and 288,000 per day--that's a large spread.

Visa claims it can do 2,000 transactions per second or 172,800,000 per day and Paypal suggests its maximum is 115 per second or 9,936,000 total per day [1]. At best, Bitcoin is able to handle 3% of the volume that Paypal is able to and it doesn't even register as a blip when compared to a single major credit card.

If we continue to read the link I cited for those numbers, we get these details:

>Let's assume an average rate of 2000tps, so just VISA. Transactions vary in size from about 0.2 kilobytes to over 1 kilobyte, but it's averaging half a kilobyte today.

>That means that you need to keep up with around 8 megabits/second of transaction data (2000tps * 512 bytes) / 1024 bytes in a kilobyte / 1024 kilobytes in a megabyte = 0.97 megabytes per second * 8 = 7.8 megabits/second.

>This sort of bandwidth is already common for even residential connections today, and is certainly at the low end of what colocation providers would expect to provide you with.

If we were to expect that everyone was to get onboard the blockchain, we would have to assume that we're all going to start sucking up 0.97 MB per second, or about 82 GB a day. This would mean that in a month, one would use just about 2.5 TB of bandwidth. If the average residential user were to want to transfer 2.5 TB for just a blockchain (ignoring modern life's pleasures like Netflix and other streaming services), you'd have to find an Internet service that would not impose a usage cap. As it stands with Comcast, if you exceed 300 GB, you'll get charged $10 USD for every 50 GB you use [2], meaning that a month's worth of transactions will cost you just about $450 on top of what you already pay for the privilege of having access to a blockchain.

This doesn't even take into account that transactions are replayed once confirmed so those numbers could end up even higher if the whole protocol isn't changed. Heck, I am not even taking storage into account which is a different problem all together.

The idea that blockchains are going to be the future is pure lunacy. It's either going to be limited to data centres that can handle this load or it's not going to be used at all. It has no future for the general public and is part of the reason why Bitcoin in itself is not practical.

Good question. The jury might still be out on this one though.
You could argue one way or another, as it depends on what is your definition if advertising. Advertising is not art but the industry used to have its share of regretful artists. Some artists in the 20th century, like Andy Warhol, made publicity the whole point of their art. It is common for film directors to raise money trying their hand at advertising before shooting features.

Despite the poor reputation of advertising in "art" circles, quite a few visual artists blurred the frontiers between the two. For craftsmen, it doesn't matter as long as they can use their skills to make something—and they need the money, too. I understand the bad rap advertising gets, especially online, and wonder why it is still seen as the dominant revenue model on the web. Still, I'd love to read cases of significant artists who used advertising to fund their art.
>How much energy does hyperloop use to decompress the entire tunnel, run the air locks, and move the trains?

whether it is more or less energy than it takes to keep an airliner aloft is kind of moot. Transport systems attached to the ground can be connected to the power grid, which is legally required to be at least 33% renewable energy by 2020. Jet engines can really only be powered by jet fuel, and exhausted directly into the stratosphere.

For anyone interested in this area, the IEEE Transactions on Information Forensics and Security (TIFS) [1] is full of papers on the so-called area of image forensics -- the identification of processing that has been performed upon an image, including resampling, rotation, JPEG compression, block processing, and more.

Consequently, another hot research area is image anti-forensics -- the obfuscation of such operations to avoid detection. (Shameless self-promotion: one example paper on anti-forensics of JPEG compression can be found here [2].)

I find it frustrating and confusing that Patreon conjures this image, and that there's good reason for that.

The platform itself is sorely underutilized by large groups of people for who it's very suitable: Animal Rescue (Rescue (many species), Trap Neuter Release), homeless outreach and care, harm-reduction, etc. All of these groups require ongoing funding, and are positioned to provide monthly backers with evidence of the funds good-use. Obviously, if they're large enough to have 501c3 status and an active fundraising branch, it's less useful, but it would be gratifying to see Patreon attempt to enable grassroots work.
True, but will other companies (Google, Amazon, Uber, Linkedin, Salesforce etc) consider me positively for a role given my soon expiring OPT and uncertain H1B ?
I hear of a lot of startups working on image detection and sound detection, but I'm wondering why there isn't anything done for scent detection. Maybe A2D for scent doesn't really exist yet, but it would limit the need for drug sniffing dogs

So you're saying that you don't know anyone who buys in the quantities that we do, but definitely know what we pay?

I think you're responding to something that's not what I'm saying here. I never claimed that our pricing is relevant to you. Just that your pricing isn't relevant to us and that you're making generalizations that aren't valid outside of your niche.
The former head of the IAEC has come out on record against this notion. She said that the paltry few nuclear power plants in development are no where near far along enough to make a difference for over 20 years from now, while renewables are delivering, albeit still too slowly, right now.

You sound like a climate change denier? There is most definitely a solution to pumping massive quantities of emissions into the air, and it involves not doing that.

> fear of climate change are the major levers being used to increase the control by those in power

Except as far as I can see it those in power (at least in the US) are doing their best to deny climate change. And my whole point is the people in power are not doing enough, hence... you know, climate change.
How does that support the cost of the infrastructure? There would have to be some cost involved.
I think that you're stretching for that. There are a number reason to suspect that a second accelerator will be less effective that the first:

* You already got advice

* You already built a minimum viable product

* You already got feedback on that product

* You already networked with people who would lead to the next round, growth, etc

* You already spent money on marketing

Unless you've pivoted, what is Y-Combinator (or any second accelerator) going to be able do to help you other than introducing you to another set of investors (that if you chose your first accelerator wisely you might be somewhat connected to

Other than that, there's the cap table that they explicitly mention, 3-8% of a seed stage company is less attractive if there is another 3-8% player involved. Similarly, an A round (that they help you get) is less attractive if 12-16% of the company is already in un-dilutable preferred shares.
Hi, thanks for being interested in OneCook!

It is OK to cancel your meal plan. As said, it's like your smart phone's data plan. It's cheaper to get your phone with a data plan, and you can cancel the data plan by paying a cancellation fee.

The cancellation fee is the number of remained weeks of your meal plan * 4. For example, you purchased the $99 with a 12-month plan, it's 52 weeks. So, if you can cancel your plan in the 30th week, then there would be 22 weeks remaining, which means 22 * 4 = 88 dollars as your cancellatioin fee. So the total of your device is 99 + 88 = 187 dollars.

The most useful bot that we use internally is a deployment automation bot that orchestrates deployments and scaling in Amazon ECS. We are working to generalize and open source that bot.

In general, I think that bots on Slack will be boom or bust, but it's clear that Slack as a platform and Slack integrations are one of the key things that make the product special and successful. We'd like to give developers the best shot at making bots successful and useful in Slack.

Here is a super simple weather bot example that you can try if you want to see what the Beep Boop user experience is from the consumer side:

Scale matters for massive thermodynamic processes for effieiceny, but 21st century technology has become much more decentralized. You don't need massive installations of solar or wind at one location, the can be distributed throughout the grid. Massive scale is possible, but it's not required once you get away from heat differentials as the core of your energy process.

What is a climate change denier? Someone who denies that the climate has and will change?

Of course stopping all production will stop changing the makeup of the atmosphere as far as humans go. In the same way stopping people killing each other solves the murder problem. Most people are tryin to talk beyond a pat level of posturing.

I'm not ready to throw all my devices and vehicles and climate control in landfill to try and subtely change the weather 100 years hence. Nor do I think that intentionally retarding productivity and growth for the same hope. In this I am intellectually honest.

Like the parent, this seems odd that just now in 2016 we find there might be another planet in our own solar system when planets are being discovered in other solar systems and galaxies all the time.

There's this from the article:

There are several ways we go about it depending on the needs of the data to be stored in SQL. All of our data in SQL and Mongo has a uuid as the primary key and effectively lets us use merge-style replication techniques, and support temporary offline use of our application.

If the Mongo data is flat, its very easy to go from Mongo->SQL, only a type mapper is needed.

The lumpy data case gets more complicated, as its dependent on the data. The complex data generally ends up translating into master/detail tables or similar ideas. Various pieces of data that is nice to have, but changes with the UI/customer needs, gets stuffed into several key/value tables (one for each type).

For the completely dynamic Mongo data we store in SQL, we alter the SQL table programmatically to meet the new schema (in part of our application, customers must be able to drive the schema). This way works in our specific application, but it requires a lot of work to make sure your users cant paint themselves into corners with their schema.

So far we haven't experienced any issues with the front-end people changing data structures, as the changes they generally make only impact fields that are not stored in SQL. Completely new features generally require the addition of new columns/tables to SQL, but every application has that issue. During startup of the server it double checks the schema of all of the tables used and updates as needed.
Digging that hole deeper and deeper there I see.
"If you look in slow-motion, the dog passes an open window on the passenger side with no alert. The handler then leads the dog around the front. Then, on the driver's side, he turns his body around and gestures toward the window. Suddenly, the dog sits. That's the alert."

As I've always suspected. I could take just about any random dog from your local animal shelter and train them to do that in about 20 minutes (look up "clicker training Zach" on YouTube, watch what he can teach in half that time). And point at the window is the cue? Amateur hour. Given the amount of time given to train a K-9 unit, I could come up with something much more subtle, and I only train dogs as an amateur volunteer, not a professional K-9 trainer.

Alternatively, many dogs that I've trained long-term will default to "sit" when they can't figure out what you want. Could have been that the dog didn't know what "point at window" means, but the mutt knows it means something. Doggy runs through his mental database, comes with no match for "point at window", defaults to "sit".

TL;DR: the more time I spend training dogs, the more I'm convinced that drug dogs are about as reliable as polygraphs, if not worse because the handler can game it.
Interesting! Getting a package from USPS in Australia is much better than getting one from UPS.

USPS -> Australia Post means that I can get the parcel sent directly to my parcel locker [1] and get an SMS when the parcel arrives. I don't need to be present.

UPS -> ??? means I'm guessing whether it'll be a local courier who has the contract or whether it'll be one of the many Toll [2] subsidiaries. No couriers are accepted into parcel lockers (unless you get a Toll parcel dropped off at a news agent).
It's really not very rich and up-to-date, in my opinion. In my experience, the vast majority of oss PHP projects started a decade ago, and they all keep certain back-compat, so they run with the drag of old paradigms.

The main issue with ads is message saturation. Like how my wife decided to buy me (for xmas) Star Wars tix so we could both go see it.

Yes, I thought it was ok, but she had to hire a babysitter and in the end, if I'd been asked prior, I would've said no, or asked for a better movie (like The Martian).

I have the feeling ads almost always sell you something you'd have been better off not buying anyway.
Exactly. It is not a requirement. It is merely a liability shift so the merchant (CVS in this case) will be liable for fraudulent charges if they do not use chip & pin. In this case it seems they just went that way to play it safe.
It's definitely one sided, I just thought the author list consisting of climatologists, professors, and scientists would be more fact-based than a lot of the other books out there. Which is why I'm frustrated that that does not appear to be the case.

Most lists of this type are silly, but for those of you looking for business ideas, this one is actually pretty interesting. But caveat: make sure you get out of the building and talk to potential customers first. Usually there's a very good reason these ideas haven't been executed on yet.
On the flip side, an investor puts money into funding an idea which they (ought to) know has a 90% chance of not working out. I don't see anything morally or ethically wrong with saying "I/we gave it our best, but the idea didn't pan out" and returning any leftover funds, if any, before completely flushing that idea (discarding all assets associated with it), putting your thinking cap on, and looking for the next opportunity. I generally don't see a problem with starting over if you're going from an "Uber for Drones" idea to a "Custom CNC Furniture" idea, for example.

Of course, that's a completely different scenario from simply evolving the idea in a different direction but still keeping the core; in that case, I agree with your point of view. For example, I do see a problem if you're going from a "Custom CNC Furniture" idea to a "Custom CNC Cycling Parts" idea. It would be pretty shady to screw over your initial investors in that scenario. It also might be actionable by the original investors if you reuse any assets you developed using their funds.

This is the thing not accounted for in Hyperloop cost projection. It's comparing the whole cost of HSR with the system cost of Hyperloop. The bunch of HSR's cost is right-of-way and land acquisition, that requires a long and costly process that isn't going to disappear because of new technology. These costs should be accounted for in any Hyperloop cost estimate. Hyperloop isn't going to magically terminate any right-of-way and land problem. Especially in dense, urban environments. DTX, the rail tunnel access to Transbay terminal has an estimate cost of $2.5 billion for 1.3 miles. Getting to downtown SF via tunnel is gonna be super expensive for Hyperloop as well.
