Abstract:

At the settlement time of the VIX Volatility Index, volume spikes on S&P 500 Index (SPX) options, but only in out-of-the-money options that are used to calculate the VIX, and more so for options with a higher and discontinuous influence on VIX. We investigate alternative explanations of hedging and coordinated liquidity trading. Tests including those utilizing differences in put and call options, open interest around the settlement, and a similar volatility contract with an entirely different settlement procedure in Europe are inconsistent with these explanations but consistent with market manipulation. Large transient deviations in prices demonstrate the importance of settlement design.

>If you are listening to melancholy, nihilistic music, especially, change your habits

I really have to take issue with this. Some of my most productive coding sessions have been to the full-volume soundtrack of Nirvana, Joy Division, Pixies, Radiohead, etc, etc, etc.

In my experience it's important that the music has to be of the "wall of sound" type that acts almost as rhythmic white noise. Also they must be tracks you already know very well - new music is not conducive to working, because it distracts your brain.
Hey! I am an introvert and love staying alone. I like to think that staying alone helps me solve problems creatively but my major problem is that when I plan things they don't go well. For me, most of the success has come from flowing along tide when I wasn't eyeing the end or reward when I was going insane with the group.

That feels kinda familiar. My experience might or might not be helpful.

I read about Getting Things Done, and I worked to track everything in one place, but I find that task tracking in two places work best for me:

1. Something like Evernote or Simplenote, for capturing notes on any device that's handy: phone, tablet, computer, etc. Being able to search really easily is crucial, to avoid duplicate topics.

2. Something like Trello for easier prioritizing and categorization. Moving around the index card analogies is much easier than moving text.

Using email as an issue tracker is an anti-pattern. It means your work to prioritize can get casually jumbled, and for me, that flow can get interrupted more easily. Ditto for Slack.

I like paper notebooks - I used one at work so I wouldn't drop any of the tasks I was juggling - but they're less portable than my phone. Before that, I had a Hipster PDA (index cards and a paper clip - http://www.43folders.com/2004/09/03/introducing-the-hipster-... ) but I had lots of notes, and searching was awkward, meaning "just write it (again) before I forget it, sort it out later," meant there was curation involved, and that using 1. above was lower-friction and just overall better.
It's hard not to see this from all sides: the saddening loss of biodiversity, the world's desperate need for these metals, and the needs of poor countries to exploit their natural resources to rise up in the world. At first I was horrified by the mining technique being described here, and then the article got into all the United Nations protections and regulations surrounding this process.

It's encouraging to know the world will be monitoring this as it happens. Often forgotten about American history is how badly we had to destroy our own environment before we took action to make things better. Much of our country was turned into barren wasteland as all the trees were cut down for industry, and it took FDR deploying a literal army of tree-planters to bring the forests back. I think we are watching the same history repeat in China now as they deploy tree-planters along their growing deserts.

So we'll watch this new environmental front. We'll read stories about companies breaking the rules and listen to pundits decry government regulations that protect snails over jobs. Hopefully we'll strike a balance and survive long enough to make asteroid-mining profitable and maybe take all of this off-world where such environmental conflicts don't exist.
I can relate to this and AFAIK there's no magic/quick solution.

Even if you find some job/project that motivates you a lot, that motivation won't last forever and eventually the lack of focus/procrastination will come back.

I work a full time as a remote software developer, and what helped me in recent years was to focus on developing self-discipline, which is what pushes you forward in the long term. And yes, self-discipline can be seen as a trainable skill.

I started by forcing myself to wake early and take a cold bath every week day. I've found that this habit helps me develop a work routine in the first morning hours. Even without having great productivity, I've found this greatly reduces the bad feeling you get from procrastination.

Almost a year ago, I started forcing myself to do something I used hate (but healthy, especially for someone that sits for most of the day): going to the gym and lifting weights 3 times a week. As the time passed, this became an habit which has an amazing impact on my work productivity. This may be because I'm following a program where I constantly try to increase the weights, giving a feeling of progress I don't usually get from daily work (Currently lifting about 4x weight more than when I started). It might not work for you, but this is what I'm doing, in case you are interested: https://stronglifts.com/

I second your pronunciation tracking site. There are often trivial syllable mispronunciations endorsed by a community that if surfaced to the attention make significant improvement in speech clarity. What is more interesting than the not-obvious mistakes(that you cited as examples) is that there is a repetition(pattern) of pronunciation mistakes specific to a group(or all non-natives).

For instance: http://ijleal.ump.edu.my/images/volume4/IJLEAL004.SHAK_et_al...

And it's more practical since it works even if people in those positions gets sick or are away for holidays.
Certainly there's a trend away from private secretaries.

But the original statement was specifically about "ultra-low power distance societies, places like Sweden", and the process you mention is also taking place in the US, which (I believe) is not in that category.

Moreover, the statement added "the idea that anyone, no matter how important, is ever entitled to an assistant or secretary is almost anathema [in Sweden]." Yet I easily found a job position for a personal secretary.

That's why I would like a confirmation that M_Bakhtiari's observation is based on something stronger than hearsay or an assumption of how Sweden compares to not-as-low-power distance societies like the US.
Ask HN: Why are there no popular web frameworks merging front- and backend?
Dear HN community,
I am wondering why I couldn't find any web frameworks which abstract the network boundary between frontend and backend. Developing in this kind of framework would feel like developing one single app, with a single entry point and a global namespace including both frontend and backend.

Are you aware of anything like that and I just missed it? Or is such framework just an unrealistic idea?
Given the prestige and usefullness of English in many countires, an app that teaches pronunciations seems to me a good idea
It's just there's a Math "religion" in the West, and Math is pretty much a sort of holy discipline that's the basis of the hierarchized school system, and I guess it makes people believe such things. It's even more prevalent in France where up till now, general high school shared their students between 3 cursus which were scientifc, economic and litterary. They are hierarchized in the way you know, and pretty much defined by their degree... Of math.
They changed this sometime in the last few months. As well as reducing the limit to 7 map downloads total, the maps paid users have access to are now updated faster than the free ones.

They don't? AFAIK explanation of one of the factors is not even that complicated:

lower physical strength (on average) => more focus on social skills (on average) => higher agreeableness (one of the Big-5 traits) and preference for avoiding conflict (on average) => less risk but also less upside (on average) => less extreme career choices but also less extreme rewards (on average)
"Smart Guy Productivity Pitfalls" (http://bookofhook.blogspot.com/2013/03/smart-guy-productivit...) were useful to me and techniques related to "no zero days" and just getting started (with a single sentence, slide, line of code) are virtually the only things that consistently work for me. These techniques are nicely summarized in "Micro-Progress and the Magic of Just Getting Started" https://mobile.nytimes.com/2018/01/22/smarter-living/micro-p....

How about ritual defamation? (http://serendipity.li/cda/ritual_defamation.htm)
> Even if you accidentally parsed "he" as referring to the male gender at first, the context surrounding the comment would quickly clarify that misunderstanding and reveal that the comment was written in a gender-neutral form.

I don't see why it isn't just as likely for someone, like the person who corrected the use of "he," to decide from context simply that the poster was mistaken about the person's gender, and to treat it like they'd treat any factual mistake. Language is about conveying messages to people, and part of the message that was received was that ratsimihah believed the author to be a man. Grammatically acceptable or not, using "he" as a gender-neutral pronoun here introduced confusion.
I'm much less optimistic than you. The amount of willful cognitive dissonance on display here is staggering.

> “Where we’ll be operating, it’s cold and dark,” says one senior Nautilus executive. “There are no tuna there, they need entirely different conditions near the surface of the ocean.”

I expect nothing less from the mining executive to dismiss concerns that the ocean's ecosystems are directly connected.

> "For Michael Lodge, secretary general of the International Seabed Authority, a UN body set up to manage deep sea mining, there’s a clear case for pressing ahead. “Are we going to continue to develop huge mines that destroy villages, alter rivers, pollute water courses, take thousands of years to restore, remove whole mountains? You don’t have any of that with deep seabed mining.”"

But this one is from the UN body itself that you are talking about monitoring this. This man just finished saying "pollute water" in the previous sentence then proceeded with the claim that this doesn't occur with deep seabed mining? How can people claim this with a straight face?

I don't want to come off as naive. The article is very good at explaining the consumer needs driving this development. 8 billion people with smartphones and 4 billion electric cars does not scale.

On the other hand, there are also hundreds of millions of people that rely on fish for their protein. Are we willing to risk destroying our oceans to save our land?
I will be coming up on my 10 year mark for working remotely this summer.

Are you truly isolated?

At work: no 1:1/group chat or video conference? We are on chat all day and dive into video or a phone call for brainstorming. I don't have that sense of isolation. Heck, some days I feel like I've wasted too much time interacting with work mates on chat.

Off work: I understand you can't hang out with your buds every night of the week but it would be an odd day if I did not talk to at least one of my friends on the phone or Telegram or play a video game together. Kids change things and they are less available to "do stuff" but we still talk almost daily. Weekends are still there to get together or an occasional after-work dinner.

Have you tried seeking out some clubs of a hobby of yours? Sports, board games, maker/hacker spaces, volunteering?

My vacations which I look forward to are still the ones where I turn off all communication and seek isolation where its just me and the wife out in nature away from other humans.
There used to be a show in the US about moving houses - generally they were wooden houses and moved a mile or so to either a new part of town or another town. I think the huge wide (and pretty empty looking) roads helped - I can't think of many cases where you'd be able to do similar in the UK due to the narrow roads.

Plus I'd rather move a wooden house than a brick or even a stone one.
I second most of this advice. I take cold showers and I exercise frequently. Both do wonders for my ability to focus. Also, see a psychiatrist if you think you have adhd.
I often try to remind myself that it is better to start somewhere, than nowhere. Just getting started is often halfway done. Even though it might turn out that you could have started somewhere else which in hindsight would have been a better approach, it is still better than nothing.
DOS was becoming outdated and insufficient in the 90’s. No multitasking, no crash-protection, no unified UI, unreliable file system. Yet it ran on millions of computers.

OS/2 was one of the spiritual successors to DOS. It was DOS and Windows compatible, could run DOS apps in parallel and apps wouldn’t crash the whole system. It came with a reliable file system called HPFS as well.

Its direct competitor was Windows 95. It bet on better compatibility and better hardware support so eventually persevered. After switching to Windows NT kernel with Windows 2000, Windows had no technical shortcomings left compared to OS/2.

After working remotely for 4 years I am switching back to the office at least 3 days a week and moving back to our company HQ in the States.

Hardest challenge for me was staying in shape, because I lacked self-discipline to workout and eat healthy, but funny enough work didn't suffer and it was the most productive period in my life.

It gets extremely easy to start slacking (no pun intended) and not do your work out. You tell yourself "oh let me just push this feature, fix this bug or communicate about a new feature". Work gets prioritized and everything else is put aside. That actually damages your productivity in the long run and the chance of burning out is far bigger than if you dedicate time to do other things.

Took me a while to recognize the trap I was in - I felt obligated (no peer pressure, but just the fear of missing out) to always be online, answer emails or slack messages. Of course, my mental and physical health suffered due to this FOMO.

Since I have about six months before I get back to the office I promised myself to tackle these things by doing:

- Fix morning routine by working out, cooking and taking time to do other things (read, play video games, hobby)

- Snoozing notifications at 6pm my time.

- Learning to say "It will have to wait 'till tomorrow".

- Spend more time outside of my apartment at night.

- Dedicate more time to my SO.

- Learn Elixir/Erlang during the weekends.
Programmatically finding whether or not a specific apartment has windows facing in the right direction would be an interesting challenge.
> More people should get to know clojure as it's a wonderful language that has almost all concurrency models on this planet.

Clojure is great. But Rust is a Must, so I hear, and you will need some Python for ML. And then of course JavaScript if your stuff touches the web, and it all does. And there is Go and Erlang or is that Elixir for systems and transactions. Ruby or PHP for RAD and Java for the large stuff can not be ignored.

And before you know it you'll be bad at 25 languages, instead of good in one or two that allow you to do what needs to be done.

All these languages are great in the sense that they exist and show what is possible but they make it super hard for a professional programmer with ~8 hours in a productive day to choose which eco system (which is far larger than just the language by itself) they want to invest their time in leading to some variation on the paralysis of choice theme.

I'm super happy I don't have to earn my bread by coding today, I sincerely would not know what to choose to maximize longer term value of my investment in time. It's like building a house on quicksand.

You have ADHD. Make an appointment with a qualified psychiatrist to see if you meet the requirements for diagnosis and medical treatment.

You are not alone. Your struggle is the result of a medical condition, and not your fault. ADHD can destroy lives. Don't let it ruin yours.

Source: I'm 35 and struggled with very similar things my entire life. It nearly destroyed my marriage and my career. I received a diagnosis 6 months ago and have been taking prescribed stimulants (Vyvanse) ever since. It was a life-changing experience. My only regret is that I did not seek help earlier, having for so long blamed myself rather than my neurochemistry, which only made me stressed and depressed without providing a solution.
It feels like you’re haven’t discovered something that you would wholeheartedly embrace as a “success“, that you would experience as a genuine pleasure. What is the ultimate game you want to play? Do you like animals? Cuddling a pet gives you a warm fuzzy feeling? That might be the feeling that you should look for when defining that „success“ in work. And once you know what it is motivation will come to you as a lucky dog or a cat asking to be petted.
Hey, of course this didn't come out of nowhere. After lots of failures on my own ambitions right after college, I eventually caved in (completely broke) and started a job in tech support to pay the bills. It was only then — where I got my problems and structure from an external source — that I started really excelling.

I eventually automated my job away, worked my way up through engineering into a Lead Architect position and started looking like a credible CTO position — meanwhile I had started doing therapy and coming to grips with accepting my real self.

So in the end, yes, I was pretty honest with my cofounders. Funny thing is that as long as someone else is setting the goalposts and calling the shots, I'm running super smooth, even in a lead role. I guess most people who don't know me a bit better wouldn't even notice I had these issues.

BTW this piece from Tim Ferriss helped me accept my own spiky personality a bit better a few years ago - as there's apparently lots of unexpected upvotes, maybe it might help others too :) https://tim.blog/2013/11/03/productivity-hacks/

I identify with you 100%. This post could've been written by me.

The only difference is I'm not a freelancer, and I've never been one. I've worked at small and large companies, and I've always struggled with this so everyone suggesting you just join a company is probably a bit naive.

I've ALSO wondered if I have an undiagnosed case of ADHD, and honestly when I look at the lists of symptoms online, I match more than half of them. I've wondered if I should talk to a doctor, but always avoided it. Maybe both of us should.
Ask HN: How do you manage “knowledge”
I am not sure "knowledge" is the right word to put it but this is something I've been struggling with, how to manage all the things that are not in your mind yet

Things to Do, Things to Learn, Things to Consume (Watch/Read/Listen), Save good things to find later (Articles, Infographics, Quotes etc), Quick Note, Unsorted Web Links, Thoughts on various topics (Impact of various tech on specific domains, better team building, various design practices etc ), etc

I sometimes spend a couple of days or so restructuring all these and then slowly I drift away to reach the same point where I started from (usually takes less than 3 months) and when I reach that stage my productivity comes to a halt, and the cycle continues

Same here - I'm ridiculously sensitive to gluten.

I've not been diagnosed, and I doubt I will ever be. I was contaminated over Xmas, and the past two months have been hell on earth. I managed to drag myself into work but the joint+muscular pain, not to mention the brain fog made me regret that decision - every. single. day.

But you have to put food on the table and pay your rent. I would never consider eating gluten for a week let alone three months. I'd be extremely ill.
Yes, it is very normal in an unstructured life, many very smart graduate students at the top universities struggle with it. It is the curse of freedom. People don't realize a regular 9-5 job gives them routine, social commitments and a visible positive feedback on a good job done in a timely manner, and a negative feedback otherwise (both positive and negative social feedback are stronger than self-awarded rewards and punishments).

I read somewhere that IBM thought by offering DOS and Windows compatibility they could lure in users, which backfired, because there was no incentive for developers to offer dedicated OS/2 versions of their software.

IIRC, the main reason it caught on in banks was that those were big IBM customers to begin with, and that OS/2 offered good support for talking to IBM mainframes out of the box.
Academia is stuck in the past in that sense. And it is already hurting them in quite a few disciplines where 'being published' is great but trumped by 'being able to afford a normal life'. So it filters out people that are willing to put their lives on hold in order to have their names at the top of a couple of papers. Some of them find that the lives they put on hold can not be put together again after a decade.

Graduate students are as a rule underpaid, overworked and if they're unlucky harassed to boot and all that for the privilege of having someone else then finally take most or even all of the credit for all the hard work.
