Per the linked article, the particular test subjects had longterm depression and had undergone numerous, unsuccessful, treatments in the past. And, while that quote seems a bit too absolute in stating that "depression is something chemical". They probably should have said something like: depression can be caused by something chemical. And you are correct that for many, maybe even most, people it's probably not chemical in origin, that doesn't mean that it's never chemical.
"1) This doesn't address the front-running issue. (Where different exchanges receive the buy/sell order at a different times and HFT can abuse those microsecond differences)"

This is only an issue if your order is large enough to take out the entire liquidity of one of the exchanges. If that is the case, by definition you are not a retail investor, you are an institutional investor and part of the value add you are supposedly adding is your ability to operate in a complex market.

"2) It's a universal truth that people who are better informed are harder to rip off. So that's not very persuasive. You can't reasonably expect regular people to know in which situations they'll be paying a premium for a liquidity service they may not even want."

So informed market participants should subsidize ignorant ones?

"3) It's completely fair to ask ourselves as a society if HFT groups are making a contribution to society that warrants the money they make. And if transparency with regard to HFT trading strategies leads regular people and sophisticated investors to make different decisions, then that means that the lack of transparency worked in favor of HFT. Therefore, it's reasonable to assume much of the HFT profits are just an externality. The decline of HFT is in part because investors are getting wise to the shenanigans."

Agreed. We should also have that discussion around dark pool operators, hedge funds, and investment banks. While we are at it, lets talk about photo sharing websites and internet chat services as well.

> I would certainly have to think a lot harder all the time if I were spending stocks or tiny pieces of land.

You said it yourself: people don't hold cash. They sell their assets before buying something with cash. And it doesn't seem to prevent them from spending. With Bitcoin, it would be the same thing except the whole "sell your assets before you buy" process could be skipped.

Of course I oversimplified a lot here. People don't literally sell their stocks/real estate before they buy something. But I'm sure they would if those assets allowed them to.

I see you've never worked in a large organization... ;-)

Bullshit jobs are largely jobs that managers create and defend in order to expand their managerial fiefdoms. A manager's influence in an organization comes partially from how many people report to him or her. That's the incentive structure that creates many of the bullshit jobs.

There are also interpersonal issues in play. For instance, you or I might walk into a particular company and observe a dozen different processes that could be easily automated with off-the-shelf software but are currently being done by humans. We might say to the manager "Why don't you automate, you're wasting money?!". In some cases, the manager would reply that the people doing those jobs are valued employees, possibly even friends, and automating those processes would put them out of work and thus, the processes are not automated.

It is a fallacy to believe that businesses operate efficiently simply because there is a profit motive. Businesses are complex organizations made up of people, with all their failings and weaknesses (if you want to call them that). It is not necessary for a business to be perfectly efficient to survive, it is only necessary that its competitors be equally inefficient.
While having a beer last week with some friends, the topic turned to the old question "What would you do if you suddenly had $20 million dollars handed to you?". This is an old question of course, on HN it would be called F U money, but it had been asked that day by a customer of my friend Kevin. Kevin makes jewelry tools. His immediate response was "I could buy more tools and machines!", which was my basic response also. I have a nice new CNC lathe on my list next, a mere $100,000.

I think it is funny, that given enough money not to work our (Kevin, me) first reaction is to think of the things we could buy that would let us do more work. For the most part I enjoy my work, and I would get more enjoyment with fancy new equipment. "who can look forward to the age of leisure and of abundance without a dread" does not seem true in this case.

YMMV of course. Given FU money, I would probably not work 40 hours a week, every week. It would be more like 10 hours one week and 80 another. When I am in the passion of a new idea, the time flies by and 80 hours feels like nothing. Anyone who has worked all night on a project and then seen the sun rise knows what I mean. I find those times some of the most enjoyable in my life.

I think humans like to do things. Make games, write software, build sandcastles, etc. Removing the need for work would not remove the work. The work would just be what we found to be entertaining to ourselves, instead of a job to eat.
'reminds me of Chile, they had a precursor of the internet for communication to the Capital.

Then the CIA had this barbecue party on the 10th of September 1973 in Viña Del Mar. And on the 11th, the country got freed, people were rounded in the soccer stadium in Santiago for a big freedom party. 'never heard again of this network and of 38000 people either for that matter. But the Chileans got 17 years of imperialist-supported freedom (3200 confirmed deaths). That's what's important.

Saudis also are very happy for this democracy that the US big brother brought to them, same for Turkey, Pakistan.

Let's stop being ironic and talk about countries who actually have had free elections since an actual open US intervention: Afghanistan and Iraq. But life expectancy there predict that you probably won't survive to the next poll anyways.

I actually very often disagree with the secret machinations of HN.

It's not that I agree or disagree with this particular banning, but that in the aggregate, "you are a new account and you post a link to youtube" is a pretty good general characteristic. While it's unfortunate that there's sometimes a false positive, most things that I see explicitly dead deserve to be.

Besides, it's pretty easy to figure out if you've been hellbanned, and then if you're real, you can ask dang (I guess, now, eh?) to reverse it. No warnings needed.

That is a completely inaccurate generalization about what HFTs do. There is a class of HFT that does latency/venue arbitration but it is a very small niche.

The vast majority of HFT volume on the other hand is traditional market making. This HFT market making is much more efficient and fair than human market making was. It is driving down the bid/ask spread to the thinnest possible levels (at least the thinnest legal levels). This is the single biggest driver to you getting the best price.

Being a retail investor right now is the best it has ever been and HFT systems are a large reason why.
I highly doubt he/she meant it in a derogatory way.
Yeah, that seems a bit uninformed, though lots of people I know who like other drugs don't like ketamine. Cocaine, ecstasy and cannabis, when you're used to it, modify rather than replace what you're feeling. Ketamine can put you on the floor quite easily, with no/a crazy understanding of the world followed by twenty minutes of learning to understand it again. A lot of people don't like that. It can be taken in more moderate doses too, but it's hard to judge how much to take (how long is a line -- the same as a piece of string; tolerance develops quickly) and one can inadvertently take too much.

I think it's under-appreciated and find the experience exhilarating.

Gumroad vs E-junkie: What's the best way to sell your digital products?
Two quotes from the article:

1. "Eight showed improvements in reported levels of depression, with four of them improving so much they were no longer classed as depressed. Some responded within six hours of the first infusion of ketamine."

2. "Lead researcher Dr Rupert McShane said: 'It really is dramatic for some people, it's the sort of thing really that makes it worth doing psychiatry, it's a really wonderful thing to see.'" [emphasis added]

Wait ... what? Saying, "Take this pill and you'll feel better" isn't how psychiatry is (or was) defined. That isn't psychiatry, it's pharmacology.

Also, none of the treatments, the old ones like talk therapy, or the new ones including drugs and/or deep-brain stimulation, suggest or identify a cause for depression. So far we've only been treating the symptoms of a disease whose cause we don't know.

I long for the good old days, the days of science, when we identified the cause of a disease, then designed a cure based on our understanding of its cause.

This isn't a cure, it's a symptomatic treatment, and to remain effective it would have to continue forever, reliant on a drug whose mechanism is as unknown as the thing being treated, just as with ADHD and PTSD. I'm sure Big Pharma is very upset that another perpetual market for drugs is opening up.
And I know I'm going to get down voted for this, but that is the most naive thing I've heard all week.
You're worried the $101 isn't actually there - i.e. if you place an order to buy for $102, either the $101 order will get pulled by the HFT trader, or the HFT trader will buy the $101 order and sell it to you at $102.

If there is a sell order @ 101 and you place a buy @ 102, the exchange will instantaneously match the orders. The exchange will then inform the HFT and you (simultaneously) that a trade occurred.

I repeatedly linked to an HFT tutorial which explains this. Please read it.

It's worth noting that the software, while only 36k machine words long, and the hardware, which was very slow even by the standards of other computers of the 60s, were remarkable works created in only a couple years by huge teams (peak of 800 people working on hardware and 400 on software IIRC).

New Assange book calls for radical overhaul of the URL system
Last time I managed to find a study showing daily browser market share, I noticed that the drop for old IE versions during the weekend was significant but below 50%. So over half of those users are not corporate users.

I don't like citing numbers without a source, but I couldn't find one in 5 minutes Googling. If somebody has a link that shows fairly recent daily IE usage share, we can double check my recall.

I would also like to add that one technical solution for the "IE in enterprise" problem would be allowing parallel IE version installations. IE already allows to go into old version emulation mode, but it's not 100% faithful (I don't know the details).

If it was 100% faithful, sysadmin could simply update IE to the latest version for normal browsing (or even let it auto-update, since I'm sure no sysadmin believe that he/she can QA IE better than MS for general Internet usage), and forcing compatibility (through GPO) for Intranet sites that are broken in newer version.

But since it's not 100% faithful, the technical solution would be allowing to install an auto-updating IE in parallel to IE8, and then configure a policy to automatically switch to IE8 for Intranet sites (Chrome Enterprise does a similar thing; you can configure a GPO so that the user is automatically brought to IE when he/she browses to specific websites, e.g.: Intranet).
How will the future of work be?
Several years ago and for a period of around 5 months I took Ketamine recreationally.

I was taking it nearly everyday and besides the effect of the drug itself, the resulting lifting of depression was very strong. It got to a point where I had feelings of intense love for people and my interactions became very emotionally charged in a positive way.

I also noticed that I had higher levels of clarity and my writing and thinking became clearer. The only explanation I've found is that ketamine reduces the level of kynurenic acid in the brain, something that I've found to have higher levels of.

As I started taking it less depression would start to kick back in 5-7 days. A relatively small dosage (not enough to get back in to a k-hole) would get rid of the depression almost instantly.

But there was a critical downside. After a while I noticed that my ability to do technical work diminished greatly. It made me stupider in many ways. I felt like I did not have access to the portion of my brain in which I could code. On the flipside it seemed to make me smarter socially, or at least give the impression as the increased verbal clarity and feelings of connection to people.

From looking around at other users at the time, I would say the effects of increased clarity were not commonly reported, and the anti-depression effect wasn't really talked about much, yet people got quite addicted to it.

At the end of around 5 months, I stopped taking it completely. I couldn't do it and hold down a technical job.
work provides purpose and dignity, and without work, you have no purpose, and therefore, you are a failure

Regardless of age, I guess most people feel this way (not just the previous generations - even the people in their 20's and 30's today). What is the alternative to this? If not work - what is important? what makes one person a success and another a failure, and what gives purpose and dignity to life, in your opinion?
Issues like the ones raised are why all sufficiently advanced database engine designs tend to evolve toward a kernel bypass architecture. From the perspective of a database engine, operating systems do a lot of "dumb" things with resource management and scheduling in ways that are essentially impossible to avoid that the database engine has enough context to do intelligently on its own. OS bypass in a database can have substantial performance benefits and add robustness for many edge cases. The obvious downside is that you basically end up rewriting the operating system in userspace, minus the device drivers, which is an enormous amount of work. It is not an incremental kind of design approach and it makes portability difficult. PostgreSQL actually does a really good job trying to be fast and robust without going to bypass internals.

I've always asserted that the reason we've never seen a proper kernel bypass database engine in open source is that the Minimum Viable Product is too complex. A bare, stripped-down, low-level database engine that does full bypass of the operating system is usually at least 100kLoC of low-level C/C++, and that is before you add all the features a database user will actually want. That is a big initial investment by some people with fairly rare software design skills.
Gotcha, that's for clarifying it. With receipts this makes way more sense :)

Isn't that a reason in and of itself to remove work? People working for satisfaction and pleasure instead of trying to make it day to day seems like a massive improvement on many societal ills we face.

This is one I'm seeing more and more often. The word you were after is "exacerbate". It's my hope that exasperate and exacerbate won't suffer the same fate as literally and figuratively, which now mean the same thing:

For me the value wasn't just the sessions, but really being immersed in this ecosystem for a few days without work distractions, and networking.

>Game of Thrones?

You mean the most pirated show of 2012 and 2013?
I don't disagree with what you say, but it feels like a lot more important issue than you describe it. The whole systemd thing was intended to rewrite some pretty complex stuff that works already, but as it turned out over time does many things wrong. And do it right™ this time. Keywords: "rewrite", "already works", "right". And I personally believe it's a good idea, because what is done wrong at low level produces more and more work, complexity and errors on higher levels. Very hard to achieve, but essentially good.

Now, the complex system with good API and architecture, but not-so-perfect internals is hard, but possible to fix and improve over time. System with bad API is essentially impossible to fix, ever. People that write optimal code without bugs, but terrible APIs and don't care about what others feel about that simply cannot "do it right™". Yeah, it may work well out of the box, but the progress goes on and after 5-10 years community will struggle to implement something new and important on top of that systemd and feel that only way to stop the pain is to replace it with some systemπ and do it right™, and people will remember 2014 year and say: "Well, we had that story with systemd already. It turned out to be no good! We'll make do without doing stuff right™."

Thinking about it I feel sad regardless it may work smooth out of the box at the moment.

I've read the front page of systemd a couple times, but have not dug into the documentation much.

Can someone give a tl;dr of what it provides over the (brilliantly designed in my opinion) daemontools, or successors like s6 [1] and runit [2]?

I hear features like "socket activation", but can this not be implemented in a helper program?

I've been using s6 to manage some ruby apps, and I've got a primary s6-svscan to start a few things, one of which is a secondary s6-svscan that manages a bunch of resque workers. This makes it easy to start/stop all the resque workers in one go. And I can also allow non-root users to manage them via plain old Unix file permissions (s6 can be controlled by writing commands to a fifo).

SQL is arguably at least as easy as any other language you can define around this idea. Usually the complications come from trying to normalize the crap out of your data and expecting a single relational model to work for all use cases.

Oddly, moving this to another domain would not make things any easier in that regard. If you tried to have a single data structure that stores all of your data for all of your use cases, expect pain.
It's worse than that -- I've heard stories from friends in government agencies of people who do net-negative work (i.e. they create work for others) and keep their jobs for political/societal/social reasons.
I personally use limit orders. I think there is an important distinction in deciding how much will be paid for a security. It makes you think about what the security is actually worth, separate from what the market order book is saying about the security at any particular time.
