This article continues to be a fantastic introduction to the distributed log and all of the benefits it can bring a project as scaling becomes more complex. When I worked at Salesforce, we successfully implemented Apache Kafka and Storm into our Pardot product to ingest and process millions of user activities per day to progress users inside customer-created automated workflows. Having one source of time series truth is pretty cool.
There’s plenty of political recourse, especially when you’re taking property from thousands of people in one project.
The paying for land is a huge cost center for massive construction projects. Especially ones that require a 400 mile unbroken piece of land. Not to mention you can tie even eminent domain up in litigation for years.
The “existing rules/definitions of i, sine, etc.” are poor places to start.

There are many ways to define these concepts. The traditional versions are needlessly obscurantist and get the appropriate pedagogical/conceptual order backwards.

The proper pedagogical definition for I is “the ratio of two vectors of the same magnitude which point perpendicularly in the plane”, or “the transformation which rotates vectors in the plane by a quarter turn”. Defining I as √(–1) and then working with purely formal quantities of the type a + bI is much harder to follow. It just seems completely arbitrary and invented (which is why people had trouble with it historically, and many students still do today).

If you define I to mean a quarter turn, then having it square to a half turn makes perfect sense. Once you know that a half turn is equivalent to a reflection across the axis of rotation, then it’s pretty clear to see why a half turn of planar vectors should be written as the scalar –1. So the property that I^2 = –1 emerges naturally.

Then when you sometime later start talking about logarithms, there’s a nice opening to talk about what the logarithm should be of a rotation. This ties in nicely with a discussion about position, velocity, and acceleration in uniform circular motion, etc.

* * *

It seems like there is some “deep insight” when you start with very obscure concepts/notation defined purely formally/abstractly and then fiddle with them a bit and suddenly out pops something simple and concrete. It makes for a good magic trick or punchline at the end of the tedious slog that is a traditional math course.

But it’s better to start with simple concrete ideas and notation which are meaningful a priori.
>with zero recourse

What? There is absolutely recourse, such as "sue them and at a minimum tie the project up in lawsuits for years". Or "be furious and rally with lots of other furious land owners/interested citizens and vote the bums out" because focused single interests, even as minorities, often can exert a great deal of political influence in a democracy. Or even illegally resisting through various means, which might not affect this area of California specifically but is a real threat in some parts of the US.

Eminent domain has an important place and has be used well, as well as abused. But whether justified or not its use, particularly in modern, is frequently fraught with controversy and political/legal battles.
noric-bot has been extremely useful as a test tool, if a bit narrow due to just spamming random cmds. To your point, the bot in its present form can't automatically run a dungeon or verify edge cases.

A previous version of the server codebase was written in ruby[1]. The playable branch of that repo has a combat demo that's a bit fun, however the performance is so terrible that I shelved the whole codebase years ago.

As a long-term vision I'd like to launch an indie MMORPG that supports at least 1,000 players per synchronous, single-threaded server. It's an item/equipment focused game. Each player may have hundreds of items with a total of thousands of affects. noric-bot helps me stay on track with that goal.

What bugs did you find or do you hope to find this way?

The server is an actor-based "distributed system" using Akka. I only ever run it on one jvm but in theory it could be clustered. The bot helps find performance bottlenecks and actor-related edge cases.

The server runs at 4fps and Very Bad things happen if the 250ms frame time budget is routinely exceeded. The bots use a special password to spawn "fully loaded" player mobs with hundreds of items and ~1k affects. This helps me see bottlenecks like saving/persistence, I/O, Akka mailboxes growing, time spent processing player cmds vs moving the simulation forward naturally, etc.

Sometimes the bot will find logical bugs. This is usually in the context of assertions I've added that the bots will trigger.

I'll routinely write fake commands that bots will spam to execute scenarios that otherwise would be unreachable (if only due to lacking gameplay functionality at this early stage).

Often I'll just run the bots for fun and see how the game feels with a lot of other "players" running around :-)

> During our one-year pilot, road turbulence was a frequent guest complaint. Cabin G2 introduces our proprietary bump-canceling technology, Cabin Cloud. Beneath select cabins, a suite of sensors, electric motors and control algorithms instantly respond to road imperfections by moving a guest’s bed up or down to control the vibration. The technology transforms a bump that would take a passenger out of the deepest sleep, into a bump that they hardly notice.

This reads like parody (road turbulence?!). I haven't done it in a while, but isn't I-5 between LA and SF is a pretty normal interstate in terms of ride quality? They make it sound like an off road experience. I could see emphasizing a quiet ride, but just about any vehicle should be a smooth one.

Technically, it's paid for by people paying credit card interest and fees, and everyone who doesn't buy things with a credit card, thereby getting nothing for the inflated prices that merchants pass on to you.

> the brand name passed the carcinogenicity tests in animals, and if the manufacturer kept their same suppliers and formulation

I really doubt this is the common case. The studies with animals and the clinical studies with human for safety are very small, so I guess they use a special batch. For production at scale they probably use some industrial method that is cheaper. They may also change the provider, or build it in another factory they own in other country.

Also, every drug has precursors, and has precursors have precursors, you can't produce all of them so you must buy some. And with many of them there are more possibilities of changes that introduce contamination.

What you get with a brand name is more quality control in the incoming products, more quality control in the process and more quality control in the final product. (And also more marketing, sometimes it is only marketing.)

> Why would the US not look out for its own best interests?

Of course the US should look out for its own best interests.

It is far from clear that leaving the global postal union is in our best interests, however.

> China refused to negotiate, believing that the US would never pull out and that they had all the leverage.

Given US dependency on Chinese products, I don't think we can clearly say that China doesn't have all the leverage.

> Keep subsidizing packages for their main economic rival? Sit back and do nothing while China continues to benefit?

Keep in mind that subsidizing packages from China is also a subsidy to US consumers of Chinese goods. Americans benefit from this too. And leaving the global postal union affects a lot more than just our relations with China.

So yes, maybe continuing to subsidize packages from our main economic rival is better than leaving the global postal union.

I don't have all the facts here, so I am not sure I know what's right, but I have enough facts to see that only looking at how fair or unfair things are doesn't give you the whole picture.

I would expect an invalid string to have an invalid length. For integer-valued lengths you'd have to use a negative number to differentiate from a valid, empty string. But then the sum of the invalid-string lengths differs from the length of the concatenated invalid strings. Which is wonky.
Threading has a rather specific meaning in cpus, no?

Synapses are parallel, but so are various operations in a single threaded CPU, even just the ALU (carry look ahead addition e.g.). Vice versa, hyperthreading switches context when the single threaded cpu is stalled by memory look-ups.

While its notable how many ideas can converge, or how you remember that name out of the blue that you couldn't figure out minutes or days before is surely interesting. But attention is pretty much directed, so to speak. Just doing a different motion with each hand at the same time requires a certain ammount of orchestration. This requires planning and training.

The brain is a super scalar architecture, sure, but you cant do taxes with one hand, paint a picture with the other, and explain quick sort to your mom over the phone while you get your ... nippeles pinched (the classic Password Swordfish situation). Or more simply speaking, you can't be angry (at the taxes), elated (because of the forms and colors) and aroused (the nipple pinching throws various interrupts, whether arrousel or panic) at the same time while remaining pleasently calm towards your mum. Well, that does not sound like a good study design, but because of the health hazzard. Come on, if you stress a metaphor, I want too.

> Byrne is the beneficial owner of 4,910,431 Overstock shares as of May 16

Why should he have to justify his sale of a fraction of that, 15% before the sale?

Jack Dorsey doesn't have to justify his monthly sales of 70,000 Square shares, typically netting him 4 million usd.

Skin in the game?

Jack Dorsey simultaneously prints completely new Class B shares, and converts them to Class A common stock, continuously diluting everyone. Jack Dorsey satisfies your would-be criticism if held to the same standard by creating new shares at $0.00 for every one he sells for millions.

What is the difference in the tolerance people have for Jack Dorsey's behavior and Patrick Byrne's behavior? The mere element of surprise and lack of pattern?

Did I miss something, or does this article say that, for example, if one parent lost 5 children, that means that on average 5 parents lost 1 child each?

It's an interesting topic and the recent bumps on the graph have me wondering what caused young child deaths to rise in the '80s and '00s.

But unless I missed different numbers than averaging all child deaths across all parents, it doesn't answer the question in the title at all.

I think relaying the image with a lens onto the colorimeter should work assuming you modify the game so the hardware displays a full screen equivalent of all possible variations of a single pixel. it might be necessary to switch to a color cube with 3 photodiodes, and perhaps read in with 3 DC-coupled audio channels, or alternatively use an arduino's ADC (I know ...) but with a proper antialiasing filter capacitor for the sample rate used.

> Personally I think DevOps is like religion

As long as no-one is knocking on my door asking if I have five minutes to discuss Agile development methodologies.

I could reasonably defend most of what people attach to the "DevOps" buzzword as sane practices most of us were already doing before the hoopla.

Agile (with a capital A) is the absolute worst thing that has ever happened to the software industry. Kill off that cult and you can DevOps my work with containerized OWASP Gitflows until the end of days for all I care.

Snark aside, Dave Thomas makes a compelling argument for trying to choose terms that are as hard as possible for others to co-opt for selling snake oil (anecdotally, I encounter people on a weekly basis who are self-described Agile or DevOps experts, but have no technical background whatsoever).

> Wow, it's almost like there's demand for a high-speed, non-driving land route between LA and SF.

We'll see, it's not like this service has proved viability yet. As other's have pointed out, this is about twice the price of an hour and 40 minute flight. While some commenters are arguing that there are some folks who would take it to skip the hassle of the airport, I think pretty much the only people who would take this are those with a pretty severe fear of flying.

No one is saying don't measure things. Fertilizer doesn't come from mysticism and homepathy but from science - make a guess (hypothesis) and test to see if it works.

Yup, I also do work that can be described as DevOps. I have strict code reviews, have to write design documents, and develop code in Python, Bash, and C for the embedded platforms I deploy to.

Ask HN: JavaScript Framework to use with pre-existing HTML
I have a project that allows users to enter an arbitrary URL and make simple modifications to the HTML structure.

Right now I am doing this all by hand using ES6 but it's starting to get a bit unwieldy.

React, Vue.js, Angular etc are primarily focused on generating a complete project, HTML JS and CSS that can be used as an application.

I want to just add some functionality to existing arbitrary HTML, but I'd like to do it in a somewhat modern fashion (things like backbone are at least somewhat better suited to this, but way out of fashion).

It seems like Vue might be my best bet but I just wanted to see if anyone else had any suggestions.

Nice writeup - I've been doing this type of thing for 10 years before type annotations by passing the types to the decorator and then using kwargs to supply defaults.

The types could also be arbitrary callables to parse things like datetime and what not. I'd parse the params from either the get params or post data (json, urlencoded, etc).

Not sure how ticket pricing works, or what sort of deals theaters could work with the publishers, but if they had only sold tickets through moviepass after the listed showtime, I feel like they could have made it work.

Moviegoers would really only be able to take advantage of less popular movies and/or showtimes because buying the ticket so late risks a sellout or bad seats (might not be able to sit near friends). The income would mostly be gravy / found money for publishers because it would mostly be people who wouldn't have gone otherwise. Moviepass might have been able to work out some sort of rev-share based on number of tickets sold so they could guarantee some income from each member's monthly payment. Hell this might even get you over the hump into AOL / Planet Fitness territory where you're almost entirely sustained by revenue from people who forgot they're paying for their subscriptions (I assume this was always the ultimate goal for Moviepass).
