The most recent polls show 68-77% of the public are against yet another union strike. In terms of general public opinion, there are, of course, contingents of uber-liberal/uber-conservitive outliers on either end; but the majority of the public are simply fed up with what is perceived as an increasingly petty and entrenched stalemate with little transparency as to what is actually being negotiated.

BART employees and their unions say salaries are too low for the (high) cost of living in the area, and should be increased by 23% to correct that. However, BART (and increasingly, the public) argue that BART jobs require no technical skills or education (beyond a HS diploma) and are benefitted and secure jobs already paying far above the average wage for jobs of similar (low) skill levels; and in light of the context (economic and otherwise), only a 4% raise should be granted. The percentage raise rates have gone back and forth on both ends, but that's the general gist.

Ask HN: Do you blog about professional AND personal topics?
I'm guessing quite a lot of people here have a blog where they write about topics related to their profession e.g marketing, development etc

Do any of you also use the same blog to write about personal topics? For example hobbies or events you have been too that are not related to your work? I'm thinking about doing this but do you think its acceptable?

In my opinion its okay to have a mixture of both. I find it quite refreshing to get an insight into people's personal lives too.

My understanding has been that the a significant role of a BART driver is crowd control as people get on and off. Some of that seems less automatable than the travel itself. I could easily be wrong about that, though, or automating the rest might be worth doing anyway.
If you've spent too much time in jQuery you might not realize that streaming is supported by the underlying XMLHttpRequest object. The readyState property can be set to LOADING or DONE. Most applications will wait for DONE so they have a complete document to work with. A "normal" payload will be small enough that the lag between LOADING and DONE is tiny, but a big download can definitely be parsed as it loads. Imagine an HTML doc with inline JavaScript. That JavsScript is evaluated as soon as it's encountered and doesn't wait for a page load that may never happen.
It does say you can use Zepto instead. Would that do?
BART is already automated. The "drivers" just make announcements, check that the doors don't close on someone's leg, and press the emergency stop button if the computer goes badly awry.
> People seem to have this idea that back in the days

I don't know who these people are. But many people today see the screens and volumes, and say "see, HFT gives liquidity!", and that's wrong. I'm not saying HFT took liquidity away (it may have, I don't know, but for sure I didn't claim that). But it does not improve the liquidity that matters to most market participants.

> executing giant orders in one fell swoop hasn't gotten any better under HFT, but it hardly seems to have made it worse.

I agree. I'm just countering the oft repeated meme that "HFT provides liquidity". Essentially, it doesn't.

> I don't know about "often," unless you're talking about trading individual issues where news events introduce a high degree of uncertainty. There's really only been one case of a market-wide drying up of liquidity, which lasted for about 15 minutes during the flash crash.

There's been tens of "flash crash" and "flash smash" events in the last couple of years. Not of the magnitude of the one blamed on Waddell and Reed, but it's still happening.

> There's also nothing new about market-maker liquidity drying up in times of uncertainty or severe volatility.

I agree. I just disagree that HFT are providing any kind of service or benefit to the market. They only benefit themselves, at a cost to the market that goes way beyond the profit from arbitrage/scalping action that they do.

And it is easy to put a stop to: Adopt the rule Eurex and LIFFE had in 2001 that requires 10:1 order:execution ratio.

Nothing is ever "proven". We merely make statements that become increasingly challenging to show are likely to be false based on human judgement of experimental methods.

P values are estimates of the probability that a given observation is likely to have come about by chance, rather than due to a hypothetical model. They have many problems and it is best to think about them with a solid understanding of probability.

If there was a case where you have as many conflicting results as you say, then it would be indicative of a very active scientific community and problem. People would be working hard to resolve the problem!

My dad and I are in a similar situation to you- terrible nasal congestion constantly interfering with sleep.

The quick and dirty solution is decongestants. However, vasoconstrictors (pseudoephedrine, oxymetazoline, phenylepherine, etc.) often have a "rebound effect", i.e. when they wear off you find you're actually more congested than you were before you took the drug. In this sense they can be quite addictive. I try not to use any unless it's absolutely necessary, and only once every few days at that.

One thing that helps a little bit is Breathe Right nasal strips. They will often open up the nasal passages enough that I no longer have to struggle to breathe through my nose. If I'm only slightly congested, I use these. I don't know if the increased air flow would be enough to keep you asleep or not, but it's probably worth a try.

For the most part, I have pretty much adapted to function on a few hours' worth of sleep. I can go on a three hour nap twice a day for an indefinite length of time. I don't know if that is enough rest to fully clean up the brain, but I don't feel crappy all the time so I suppose it's good enough. It definitely works better for me than sleeping for 6 hours once a day. I typically sleep in on the weekends, but I recently saw an article claiming that isn't enough to erase slept debt accumulated during the week.

This looks really cool! I'm confused about the usecase, however. In your foods/nonfoods example[0], it allows you to request a some JSON with 2 keys, `foods` and `"nonFoods"`, each with an array value, and use only foods, discarding nonFoods. You request this from oboe('/myapp/things.json')

My question: why not modify the backend to accept a request like `/myapp/foods.json` and let the backend compose the json you need & send only that? It seems like fixing it "in the wrong place" to build your frontend to accommodate getting the wrong/too much data. Is this a contrived example that isn't the core usecase? This is my assumption.

Is this primarily for 3rd party APIs and legacy codebases where it's impractical to change the response type & updating to e.g. sockets is impractical? Thanks for the cool project, I apologize for my ignorance wrt whatever points I'm missing!

Also another mistake here is the classical "if you want to measure x, don't measure y".

If the OP wanted to measure function with or without return , even without realizing how futile that is, they still should not include things like jQuery.
The most important metric is excessive inflation, and the secondary one is exchange rates (though changes in that have mixed effects). These are empirical facts of the matter.

There's lots of theories about how this or that or the other thing might cause high inflation and/or devaluation. But when you look at the track record of these theories they are pretty horrible. QE1 and QE2 was supposed to lead to imminent hyperinflation. It didn't happen. The S&P downgrade was supposed to lead to yield spikes in treasuries (which in turn was supposed to lead to heavy inflation). It didn't happen. Deficit spending was supposed to lead to bond vigilantes coming out of the woodwork and cause catastrophic inflation. It didn't happen.

As a formal matter the government doesn't even need to issue bonds. Under this view (which broadly speaking goes by the name MMT) the government doesn't have a budget per se at all. When a bill comes due they can just create dollars out of thin air to pay it. When taxes or other fees are paid to the government they don't get stored anywhere to be used to pay bills, but instead cease to exist. Advocates of MMT suggest that the government tweak outflows and inflows not with the aim of balancing a non-existing budget but rather based on managing observed metrics (mainly inflation).

Critics claim that a move to such a system would cause hyperinflation. Who knows, they might even be right for once. The important take away is that the US government is not just a really big household, and US treasury bonds are not just like a credit card.

The issue is that the global diet for treasuries artificially holds down interest rates. If purchases slowed or holdings were sold, interest rates would rise. Whether it would be a crisis or merely hurt is a marginal distinction.

The government of the USA would go bankrupt in months if interest rates rose to 5%, which is an historically normal figure.

Even positive results aren't always convincing when they go against the scientific mainstream. For example, consider the
Avery/Macleod experiment that showed genes and chromosomes (and thus the heredity) were made of DNA- positive result, easy to analyze the methods and results- and frequently ignored.

It wasn't until the far simpler and more unambiguous experiment- that even physicists could understand- Hershey/Chase was done. But oddly, it was a negative result when it was published: "protein is not the heredity molecule" although by reasonable exclusion, one could easily conclude that DNA was almost certainly the heredity molecule.

Even then, a lot of other evidence was required for the mainstream community to accept this. Protein bias is long and exists today.

I've not been following the connection between currency valuation and threat of default. I'm not sure if it's just my not seeing some connection (certainly possible) or others conflating things that aren't actually connected. Why should I expect less demand for my dollar a week after a US default?
I suppose the example is a little artificial. It isn't really for using some of the JSON response while ignoring the rest (well, you can use it for that but it isn't the main use).

I got the idea for this project working on data vis. Not all of the data was visible and we wanted to display the first bit of data quicker without waiting for all of it to arrive. We could have just sent the visible bit but it was good to have some data ready in the off-screen section for when the user scrolled.

Before that I worked on a service where we were aggregating 6 or 7 services into a single JSON. Some of the services were quicker than others but because the AJAX lib we were using waited for the whole response they all had to go at the speed of the slowest component.

We could have done multiple requests but it was more elegant to serve a whole page's json in one call. Also, we cached the slow services so they were only sometimes slow.

Carmack wasn't the only one behind ID (and therefore his own) success. Sure, he was the technical genius behind the game engines but he also was working with incredibly talented level designers, artists, and gameplay tweakers. Even other programmers like the legendary Michael Abrash. 'Hire the best...'

The other big part of their success was the direct marketing. Even if Doom was as successful as it was, they'd have made only 1/4 of the money if they used a traditional publisher.
It doesn't sound capital efficient at all - instead they've got people deliberately milling about doing nothing while waiting for the "penalty window" to lapse.

If anything, this is a brilliant example of how applying measurable incentives can distort motivations and make people do stupid things to please whatever metrics are being measured.

Left to their own devices, these very smart and ambitious people would no doubt make up their own mind about the value of their time and ensure they don't waste time milling about when they're busy, and so go to lunch early or late or in the middle if they're not too busy anyway or want to chat with someone in the queue. Instead, they're now forcing themselves to fit a stupid "penalty window" to save a few bucks, because that's what the incentive system in place dictates.

Measurements are a very, very dangerous beast. Apply with caution.

True.

It was never available in the areas that people wanted them most. Hobbling sales was more of a decision by Google than a lack of demand. I suppose Google just wanted to show that a device could be built at this cost and prove a point. Here in India the demand for the Nexus 4 is HUGE however, after taxes, import duties and markups, it retails for around the same price as a iPhone 4s which a lot of people prefer as a status symbol, never mind capability. Most discerning techies however, carry a nexus.

They're not taking this far enough, imposing a blanket 25% discount nothing but autocratic perversion of what could be a functioning lunch time credit market.

It is not a question.

In many countries it is illegal to ask question about sexual orientation, religion, marital status, age or even race. Assumption is that such information could be only used for discrimination. If someone would be compiling list of gays at my old workplace, I would probably call the police.

Disclosing sexual orientation to close colleagues after couple of weeks is fine. Scarfs and other sings are also fine. Proactive disclosure at inappropriate moment (job interview) would be probably interpreted as harassment (hitting on someone), same way as saying to woman "I am straight". People who organize gay parades etc.. are perceived as extremists who milk public budget.

I hope I explained it well without sounding homophobic.
