I would prefer to hire some directly, and pay him directly, instead of suing this kind of site for that. Trustable, reliable cleaners have no abundance of work. This kind of website is good only for connecting yourself to the cleaners initially, but in the long-term I would be much more happy to just pay someone directly.

Also, everyone who uses home cleaning services usually uses them recurringly. I don't know what kind of value this kind of service can add, except in the initial "find the cleaner" part.
Show HN: Caller Notes, desktop app that pops up during a call with shared notes
Also interesting that HN is moving (has moved?) toward a curated site. HN asks for reposts of things they deem good. They also adjust downward the score of many articles. (As can be seen through large jumps on sites that track article ranks, some of which will be automatic from the flamewar detector, some of which is likely manual.).

It seems like we're reaching a "web 3.0" which uses users to do the expensive bit of an intial sift but then the site admins edit/curate that into their own vision.

Earth-Venus-Jupiter has been proposed; I assumed that Earth-Venus-Mars would have some benefit. I stand corrected.
My current project consists of ~7 microservices, which has been wonderful for many reasons but exposed us to substantial complexity on this score. At present ~2 of them have to receive communications internally or externally over HTTP, so we have those fronted by a proxy to make service discovery easier. (It is, regrettably, not an off-the-shelf proxy, since one of them required application-specific routing to a sticky host(s) depending on the contents of the HTTP request).

The thing which has made our lives MUCH easier from an orchestration, discovery, and routing perspective is NSQ, an OSS message bus. It's an event model rather than a request model -- producers of events say "Hey world, by the way, EventType just happened." and consumers can register to say "Apropos of nothing, please tell me about any EventType" without producers or consumers having to be aware of each other or aware of what a consumer intends to actually do with regards to the event.

Events go into topics ("a type of event") and each topic can have an arbitrary number of channels ("one thing which should happen for each event in this topic"). If you're clever about where you raise events, you can stitch together arbitrarily complex systems by just adding new consumers on new channels, without having to make the producers aware of the new functionality at all.

Concrete example: We wanted a log of all orders made to the stock exchange. We have a little utility, nsq-to-s3, which takes all the events on a topic/channel, persists them in memory/disk for a while, and periodically flushes that log to S3 for long-term storage. This trivialized the logging feature. (I was going to write our own nsq-to-s3 but an OSS project of that same name existed and was adequate to our needs, so we didn't have to go to 8 microservices... yet.)

This was much easier than making a generic S3 logging service and then making edits to seven microservice codebases to make a HTTP request out to the logging service, with e.g. retry/failure recovery/monitoring/etc, everywhere in those codebases we wanted something logged to S3.

True its a man-made desert (despite some published nonsense about 'shifts in the earth's axis' causing weather changes). So are most of the ecosystems on the planet, by now. The issue is, changing relatively stable ecosystems is done at our peril. I just want to point out how little we really care about this stuff - to the point we enthusiastically endorse mega projects that amount to terraforming, with so little discussion.
The main problem I've seen with Objective-C is due to the fact that nil has truthiness, so this code is dangerous:

if (input.isInvalid()) {
reject()
} else {
accept()
}

If input is accidentally nil, it's an invisible bug.

The other main complaint is when you have a long string of methods unexpectedly turn out nil at the end, it's a pain to figure out which one it was.

The debate sure. But the reality of it is that right now this company has a competitive advantage because it is the only one or one of few that pay more than the others. It is likely swamped with resumes and can pick and choose the best of the best in nearly every position. If an actual minimum wage was mandated by the government at this level, the advantage falls apart and it likely no longer works.

So PageRank was an algorithm, and RankBrain is an AI? I'd love to understand a bit more of what makes them different from each other. I don't feel as though I've seen the search results become any better. In fact I've been frustrated by how many words it leaves out without telling me. Or how it says "here are the results to your search" when in all honesty it had 0 results to my search.

All jobs have lulls and busy times. But what this comes down to is that employment law costs money. How much? Between $7000-$10000 per employee.

It's a no-brainer to cut out employment law and make the choice between "work crappy consultant job or don't work at all", that is, if you can sustain it. Homejoy couldn't, because of gross mismanagement and eventual reclassification by the IRS.

The ultimate goal is to remove all human labor from the market. UBER already came out with that statement: they want to automate their fleet as soon as possible. It's also the trend of every company to reduce labor, increase automated work, lower wages, and increase profits. Damned be the employees/consultants/1099's/hoi polloi.

Why am I against "Sharing economy"? I'm not. What I'm against is "What are we going to do with 50% unemployment?" Republicans can't even contemplate science, and are busy bickering about climate change. Democrats have only a basic view of 'workers good, companies bad', except when they are being funded. But still, the question remains is "How do we transition to an economy that can handle massive unemployment with a great deal of goods and profit being made?"

In addition, many theories have knowledge gaps that scientists are happy to temporarily plug with placeholders, in the expectation they'll eventually be filled in with permanent replacements.

Dark Energy and Dark Matter are two such examples. They're just keeping the seat warm until we actually have an idea what the hell is going on.

A particularly long lived example was the heredity placeholder in Darwinian evolution that survived nearly a century before Rosalind Franklin et al., finally filled in the gaps.

I'll just throw in a plug here for Prof. Abu-Mostafa's Learning from Data course at Caltech, which is outstanding: http://work.caltech.edu/telecourse.html

Unlike Andrew Ng's Coursera Machine Learning class, it is a real, unadulterated Caltech class, and exactly as challenging as that implies. It delves much more deeply into the mathematics behind ML, and the homework assignments are quite time consuming.

I took it as part of an interactive session through EdX, and the professor himself was extremely active on the forums: responding to student questions, clarifying lecture points, and giving homework suggestions--seemingly at all hours of the day and night.
I have heard from several folks that they use Kafka where we'd use NSQ, but have insufficient experience with Kafka to give an informed opinion on the tradeoffs. I will say that few technologies I've used in my career were as easy to adopt as NSQ was.

I agree. It's not terribly surprising that some countries are nitpicking though: the solar industry is young, small and relatively poor. The nuclear industry is established, big and relatively rich.

Yeah, this is a good point, since an unchecked checkbox isn't transmitted in a standard HTML form, but Rails does add a hidden input element with the value false; so I guess #blank? does somewhat increase readability here, but this could've and should've been fixed in a better way (a few ideas come to mind).

Don't get me wrong, I probably used #blank? (and might in the future) just for the sake of convenience. However, it makes me feel guilty when I do, because it could subtly introduce and hide bugs due to lack of more adequate checks.

Extremely weak under an active attack: 'sed s/\([^ ]\) */\1 /g'

What you want is something that cannot be easily removed from the message without also affecting the meaning of the cover message. I am thinking of some sort of encoding that uses orthographic errors that are not trivial to fix automatically (e.g. substitute words with valid homophones, instead of changing individual characters). That would be still easy to detect, so you probably need a very low bandwidth channel to make it indistinguishable from a typical text with mistakes.

Doing this with multimedia is probably far easier.
I find it funny that you suggest compound selectors as an alternative to nesting, since nesting exists primarily to avoid the repetitiveness of compound selectors.

I can agree that it might encourage some people to nest more then if they did it by hand, but in my personal case, I was writing long compound selectors already. The ability to nest only made the styling DRY-er and gave it visual structure.

High specificity is definitely an issue that needs to be dealt with, but I'm not sure the best solution is to stop using a feature that possibly encourages it but also brings many other useful things to the table.

To end on a constructive note - don't forget you can use nesting to concatenate string names as well. .button { &-big {} } will produce .button-big {}, which means you can do some sort of visual nesting without producing unnecessary specificity.

It's fairly easy to avoid pink-salt. Hebrew National hot dogs don't have it. "Uncured" bacon doesn't have it.

Problem solved without much compromise (IMO all-beef, nitrate/nitrite free hot dogs taste much better Oscar Mayer or Ballpark anyways but I love my high(er) quality meat-in-tube-form). Does celery seed fall under this?

BTW, "traditionally" cured bacon tastes better than "uncured" IMO, but it's pretty much impossible to find IME outside of boutique butchers. The "uncured" stuff is pretty easy to find these days. A few years ago it was hit & miss but now even the Fiesta (a lower-income anglophied Supermercado) around the corner carries it. I guess there's just a lot of economic incentive to use the pink-salt shortcut.
You can't encrypt things using a cryptographic hash function:

https://en.wikipedia.org/wiki/Cryptographic_hash_function

The first part of the article talks about CAs no longer signing certificates using SHA1. That means older browsers or crypto libraries won't be able to verify a CA's SHA2 signature on certificates issued after January 1, 2016. Users running these older browsers or crypto libraries who connect to web sites using SHA2-signed certificates will get an error similar to the error they receive when connecting to web sites that use self-signed certificates.

The second part of the article talks about modern web browsers throwing an error when connecting to web sites that use SHA1-signed certificates, similar to the error users receive when connecting to web sites that use self-signed certificates.

It's a damn shame that X.509v3 doesn't support multiple signatures on a single certificate. That would really ease the transition to new signing algorithms. I can't really fault the CAs or browser developers here because X.509 doesn't facilitate forwards compatibility.

Flamanville, at 10.5 billion euro for 1.6 GW is not nearly as good as watts bar 2. This has had serious delays due to quality issues detected by its regulator. As had the finish and Chinese units build to the same design.

Sure these are supposed by GenIII, but are currently not competitive in any way with other power sources in economic terms. 10.5 billion buys you about the same in offshore wind e.g. 3 london array installations ( 2 billion per 600 MW * 50% capacity, compared to 10.5 billion per 1600mw * 90% capacity) = 10/(1.6*.9). Big difference is london arrays take 1 year to build instead of 10 for nuclear. That alone gives a mayor difference in real project costs.

Or that lip service is paid to conflicting points of view (even if one side is nonsensical) in order to create a sense of false equivalence and therefore controversy.
Yes, that's what happened, but I wouldn't say it was planned. Popular wisdom at the time was that the corium should have melted the whole way through the containment vessel.

The "popular wisdom" is utter propaganda bullshit; have you ever wondered why the popular at the time and mentioned in [1] "China Syndrome" is for some inexplicable reason is not longer bandied about? The design of the reactor vessel allowed for this and withstood the stress without the bigger concrete containment vessel even coming into play. Note even in [1]:

Besides the insulating property of the fuel and the strength of the steel vessel, previous studies had shown the concrete bases on which U.S. reactors are built also would hold up against melting fuel, Beckjord said.

That you are confounding the reactor and containment vessels in your posting suggests to me how effective that propaganda has been.
>There's really no "right" answer to how asynchronous courses should be.

Sure, but given Coursera's popularity it seems to be doing something right.

>On the other hand, if you run things on a tight schedule, real life will get in the way for a lot of people in that many of the better courses are fairly significant time commitments.

But is it? The time commitments are watching few videos, learning and doing the assignments, all of this in a week. I think it's enough even for people working full time. If you don't have enough time on your hands to do all this, I'd argue you don't have the time required to complete the course.

Furthermore having time constraints is very important for students to keep on track.

A lot of people don't like dupes because they feel that karma for posting a story should go to the first person to post it. To them, it seems unfair to post a story and get no karma points, and then someone else posts (reposts?) it a day later and gets hundreds of karma points.

Personally, my opinion is that since karma points are made up and worthless, it doesn't matter. Allowing dupes makes it more likely that cool stories will hit the front page, at the cost of annoying a few people. Seems like a good tradeoff to me.
