Ask HN: Small business ideas with decent ROI?
What are some small, historically proven business ideas that can possibly be executed profitably in couple of months?
Not the OP but the way I achieve that is by getting up at 5:30AM and running for 60+ minutes. I wasn't always such a morning person but routine exercise was important for me and so I adjusted my lifestyle to match.
Stop calling your web APIs 'RESTful': it doesn’t mean anything anymore :(
I love how this process was reengineered in London Gatwick airport.

Each scanner has 6 pods where you can pack and unpack your stuff; you've got a dedicated person assigning you to the pod. The process felt much more parallel rather than serial.

Edit: managed to find more info on it http://airlines.iata.org/analysis/smart-security-getting-sma...
As curricula changes, what's falling through the cracks
Let me put forth an alternate theory. Everyone is suggesting this is a scam for more money, which is undoubtedly the most likely explanation. However, I think an alternate explanation is that this may be a larger ploy to try to bait the real Satoshi out of hiding. Get him to say "No, that guy's a poser, it's really me." and while he's out, say "Hey man, what do you think about the blocksize?" This could explain Gavin's participation; pulling out all the stops to try to "save" bitcoin by getting founder-approval for a blocksize bump.
I fly out of ewr often, security is fast and easy. What sucks is flight delays.
I'm not sure if it's that simple. My body maintains a low but healthy weight no matter what I do. I can avoid sports for years and eat as much as I want, to the point of feeling uncomfortably full, without increasing weight. It seems likely that in some or even most obese people, a regulation system has been broken.
It's posted on the first weekday of the month so more people will see it.
> I'm just wondering why there seems to be more empathy towards people with eating habits problems, than when it comes to other addicts.

Because 75% of the country doesn't have a moderate to severe coke addiction. "Addiction" is what we call behavior that falls outside the "normal range" on the bell curve. What the majority of people do is by definition "normal" and so when you have a problem that afflicts the majority of the population, the problem is considered structural rather than aberrational.
Body searches to travel without suspicion of wrongdoing are absurd, period.
People in the UK who want to complain about this could try the ICO who strongly regulate health information.

They could also look at any advertising material and report that to ASA (if it meets the criteria for being regulated).

That trust has a Caldicott Guardian who will be responsible - legally - for keeping patient data safe. I would have liked a quote from them, although I guess that quote would be something like "No patient identifiable data has been shared with DeepMind". That would be scary, I have no doubt that DeepMind would do a very good job of de-anonymising data, but I know that Google would have to be monumentally stupid to try that.

There are other data projects happening in the NHS - care.data (that dot isn't a typo!) is one that got a lot of attention. That allowed (after some fuss) people to opt-out. (It didn't allow people to specifically opt in to show their support, which is something I would have done.)

I'm a bit wary of Vice's reporting here. They don't seem to know what they're talking about (there's nothing about controls over patient data in the NHS, for example); they don't seem to have approached the Trust involved; they haven't done a good job of explaining what's going on.

There are some really bad failures or data protection in the NHS (especially around mass email! People using CC instead of BCC to a group of people using an HIV clinic, for example) and there are some historic abuses (selling data to insurance companies) that led to changes in the law.

So I don't know if this is terrible and deserving of anger, or okay and poorly reported, or a good thing with misleading reporting.
Well 2 thing stand out for me from links you mentioned:

> The applications use a combination of Thales proprietary middleware written in C combined with Java code enabled by the Java™ Native Interface (JNI).

> AONIX has additionally delivered professional services to help PERC Ultra users at Thales optimize their applications and improve execution performance including, a customer-specific training course handled the needs of coding in Java™ with hard real time constraints.

Seems like with helping of C and Consulting on 'How to do Java right' they made it work.

> End-to-end distributed thread timing constraints measured from stimulus to response are typically under 100 ms.

Since it is slightly faster than typical (per char) typing speed on keyboard. It appears nice but terribly impressive real time Java use case.
If you believe the internet memes, the desk was not invented until 1980. Ditto the car, the burbs, the commute...

Pictures of my great grandpa's accounting firm open office compared to a typical 2016 open office from 1920 (yes I'm old, a sterotypical HN reader's G-Grampa would be in the 50s) are pretty enlightening WRT just how little of an effect the magical post-1980 desk has on obesity.

Now what happened in the 80s ... well, not the magical fat generating desk. HFCS? Hmm. What a coincidence.

Another pictorial example of a consistent social class for decades is the local masonic lodge has an annual pix of the lodge leaders and members going back to the civil war. Yes a hallway lined with over a hundred annual photographs. Even among the semi-wealthy who sat at desks all day, nobody was fat until post 1980s pix. I'm the first in four generations not to be a Mason.

If you're into genealogy its very interesting to pull group family reunion photos from the last century or so. Same people, same genetics, same social class, same lifestyle, same geography, suddenly in the 80s people start getting real fat, across the board, across occupational classes, across lifestyles. Even the jocks got fat (note that jock fat is a staggering doubling of body fat from 4% to 8%, they're both skinny compared to the general population AND twice as fat as they were)
That doesn't explain it though, as how much you weight and how happy you are with it should influence how you eat.

Obviously a kid and an adult, a sedentary female and an international athletes have different needs.

When you have tooth problems, you go through a lot to have it fixed. When your hair looks bad you get a haircut.

Some obese people change their lifestyle and lose that weight. So what about those who can't? Is it too hard because of whatever predisposition (or, as other comments point out, having a huge industry putting tasty things in front of them), or do they just feel better being big?
Yeah, this is what I'm curious about. All the weight loss diets described in the article seem quite extreme, some even dangerously so.

Maintaining something like a 200-400 calorie deficit will lose you weight slowly but surely, and maybe hopefully not cause extreme changes in metabolism?
Time management
What do you use or what has helped you in organizing and using your time effectively? whether it is software/a pen and paper or a lifestyle change I am curious what others use to successfully manage their time.
I don't think it's just that, although many have found it suspect that the dairy industry gave a lot of funding that helped the development of the original food pyramid with dairy as a core food group.

To me it's more like the current environment, to borrow a programming term, makes it difficult to "fall into the pit of success."

The NYT ran a great article on this a few years ago: http://www.nytimes.com/2013/02/24/magazine/the-extraordinary...
I get up from my desk and go to the gym mid-day or I do so at the end of the work day depending on my flow. Also, I've cut most meetings out of my life, especially pointless time-eaters like daily scrum.

Also:

1. No kids

2. I only watch 4-6 hours of TV per week

3. I walk to work, there's an extra hour right there at the expense of a higher rent (totally worth it). Previously, I worked from home

4. Most of my social life revolves around exercise rather than tech

5. Don't work for self-destructive managers

TLDR: Find your way to a results-oriented rather than a process-oriented position.
Just go get pre check?
Just start to write down every single calorie (and perhaps the macros) you consume during the day. This way it is pretty easy to see if you are on the right track.

Most people re-gain weight after a diet because they fall back into their old habits.

For this reason I don't like the idea of "making a diet". It kind of implies that you suffer for 8 weeks to lose some weight and then you can start eating unhealthy again because your diet is over. Forget your idea of "diet" and do a permanent change in your eating habits. If you do it slow you will not suffer that much and the effect will be permanent.

7) Hang all responsible for the creation and continued funding of the TSA from low branches in the middle of Central Park.

The loss of life will be a tiny, tiny, tiny fraction of the person-hours burned by the meaningless and expensive folly that is airport security theater, I assure you.
Inevitably I find the behavior of my fellow passengers much more insufferable than the TSA.
Dangerous Fictions: The Writer Mohammed Hanif Probes for Truth in Pakistan
As a software engineer who does this - you make time for it.

These days, I work out during lunch usually. I used to hit the gym on the way home in the evening. I take public transit and it was right at my stop.

It's not different than any other industry, honestly.
Overuse of the banhammer is not limited to left-y subs and the dreaded "SJWs". Happens frequently on all sides. /r/the_donald will frequently ban for comments made in other subs, as will /r/conservative. Culturally conservative subs like /r/TrueChristian or /r/European will ban easily as well. Of course, some of the lefty subs will too. Some ideologically focused subs, like /r/kotakuinaction, will allow dissent but most of it will get so viciously downvoted it might as well be censored.

And you know what: I don't really have a problem with that. Wanting to keep your political sub, left or right, focused on a particular ideology, without the distractions of debate from those completely opposed, is not a bad thing. Happens all the time in the real world. The DNC is not going to allow Ted Cruz to give a speech, nor is the RNC going to invite Bernie. Your church, assuming you have one, will probably not be inviting atheists to say "God doesn't exist" from the pulpit.
I totally agree. Lots of parts of the body are in conflict at any given time. For example, visual stimuli "compete" for cognitive processing. There's no unified "you", so it makes sense to say that part of you is trying to lose weight while another part is trying to gain it.

It's certainly not dualism in the Christian sense, but the idea that the mind is made up of many semi-independent agents has been around since at least the 80s, probably earlier.
People generally do what those around them do. Why was smoking so much more popular 50 years ago? Why do people still smoke in 2016? Why is spanking almost child abuse, now?

It's not like we're rationally considering each small action. Instead, at any time, in a give society, there are a set of behaviours that are considered within the normal range. We're mostly on autopilot.
I don't think that it actually breaks down that way. In my experience both conservatives and liberals are composed 80% of people who can talk rationally with only their own side and 20% by who are prepared talk rationally with people from either side. You need to be a lot more knowledgeable about a subject to constructively discuss it with someone who disagrees with you.

A big part of the problem, then, is that if you are not paying close enough attention it looks like your side is 100% reasonable and the other side is mostly unreasonable, regardless of which side you are on.
there were 250k ppl on the street in berlin. marching against ttip.

>It was kind of an illustration that it didn't make sense. I mean I can understand targeting teenagers vs adults but as a 52 year old I watch / read much the same stuff that I did as a 25 year old.

Yes, but the difference is, this time it's not made for you. E.g. same way I could still watch the teletubbies -- even enjoy it and look forward to the next episode, it doesn't mean it was made with my demographic in mind.

The idea is most movies will show sub-40 people, sub-40 aspirations, sub-40 plots, sub-40 situations, be based on sub-40 concerns, and sub-40 fashion, etc.

> I wonder why...

My guess is -- correct me if I'm wrong -- it's because you're not a doctor or researcher who works in any of these areas (nutrition, obesity, addiction), and haven't read much research on the intersection of these topics.

> I think obese people fit the definition of addicts.

I'm curious how you have arrived at this conclusion.
It's been a while, but the last time I researched credit cards for chip+pin the US didn't have any readily available - they're all chip+signature. Even though you have a PIN I can guarantee that it's only good for cash-withdrawal transactions (e.g. as a debit card or a high APR cash advance).

If a terrorist wanted to kill a lot of people confined into too small space to run away, what better target than these densely packed zig-zag queues? Really, what's the point of protecting a plane carrying hundreds of people by putting those same people into harm's way like that? It already happened in China - Muslim terrorists killed dozens of people waiting in a ticket hall a couple of years ago.
>Fifty years ago, two-thirds of the USA were not obese. Biology has not changed in that time. What has?

Other commentators have mentioned the food aspect, but there are significant lifestyle changes since the 50s. The rise of the suburbs greatly reduced the amount of walking for many Americans to basically just walking to a car in the morning and walking from a car in the evening, with maybe some walking back and forth to a bathroom or water cooler in between. Contrast that to the past where most American cities were laid out with public transit in mind (including LA; it used to boast a larger rail system than NYC). This meant burning more calories just to exist.

I myself moved from the land of sprawl to a walkable urban city and I lost quite a bit of weight since most, but not all, of my trips were on foot, bike, or public transit. Very few trips were undertaken in a car. I then moved to NYC and get even more activity, though that's counterbalanced by the delicious food everywhere.

You'll notice that most walkable urban areas tend to be slimmer than sprawling areas, all else being equal.
>Are there benchmarks comparing equivalent programs in Go and OCaml?

Yes. Go was nearly as bad as java and C++ in 2014, and it has gotten nearly twice as slow since then. And yet "compiler performance" is the excuse for not having generics. While C++ and java both have them and are now faster than go's compiler, and ocaml is way faster and has them.

What you're saying is "statistics might tell one story, but let me tell you, without citing sources or evidence, those statistics are wrong".
We passed that long ago.
I don't think that's how hunger works. Do you think hunger is triggered by an absolute number?

Isn't hunger the sensation you feel when your body starts dipping into your fat reserves because the content of your stomach / blood is not sufficient?
Timestamps: it wouldn't be hard so much as expensive, because the program would have to go off to the kubernetes master for each resource to figure out the timestamp. This adds up when you're doing a `find` or even an `ls` on a pod. Could add it as an option though.

Yes, writing values is very much possible, and the replica change is not a bad idea actually. Might give that a go, thanks!

There were plenty, and the ones that did were great. If you browsed the Diary section, there were running short story collections like "Fast Times at Phillips 66" that were just amazing.

I stopped paying attention around the time that they required payment for new registrations, and then shut down registrations completely. The dupe-account roleplaying was among the best aspects of the site.
They don't force anyone to do anything. They just refuse to accept currencies for taxes, other public debts, and government purchases. That's what creates the adopter base and the lock-in.

Bitcoin is a game changer. It is held up by pure faith alone. That makes it more of a commodity than a currency. For example, Gold made good currency simply because of pure faith.

I can't pretend I know I where the blockchain will lead us, but personally I'm fascinated to find out.

(Quick P.S. for any Brits or Aussies, us Yanks referring to the blockchain just means blockchain tech, not specifically the Bitcoin blockchain.)
It's worse than just membership fees. To join a precheck program, you need to submit personal information that they constitutionally can't force American citizens to provide, even at international borders: fingerprints and retina scans. So basically they hold huge amounts of your time hostage in order to force you to provide what ought to be protected info.

It's similar to incentives for long-term contraception. The government can't fine you for not taking contraception -- that would obviously be monstrous -- but they can raise taxes and then offer rebates to people who submit to it. It's lunacy.

I think Trump would abolish the TSA. Cruz has said he would, too. I'd like to see either one get in, though I wonder if the President should be able to just decide on his own to shut down an agency that Congress has approved.

Why has Congress not shut it down? I don't think anybody really likes the TSA, so I can't imagine there'd be too much opposition to a bill abolishing them. It affects so many people you could probably get elected just on this issue alone.
The best solution is to have everyone go through it. No fast lane, no special categories, just eveyone lined up including those in private jets. If the powerful had to stand in line with the plebes then the TSA would be history before the end of the month.
While these people are on the show, they are living in house with other contestants. You can't just order a pizza and sit on the couch with TV cameras and your co-stars watching you.

They're forced to exercise for hours. If you're at home you're not going to wake up at the crack of dawn and do a 5 mile run and then do weights.

They're forced to eat right. Food selection is limited. There's no cheese and donuts and fast-food.

It's no wonder that it's impossible for them to keep this up. They just go back to normal which is 'being lazy'.

> It sounds like Prometheus needs to run properly on a single box for simplicity but over time needs to be broken up and made scalable beyond the bounds of a single server.

I can understand the reasoning behind them building for a single node. Building distributed systems is hard, not everyone is capable of building these systems. They also require languages and frameworks suited to working in clusters. Golang might not scale too well, but its great for the simple things.

> The chosen approach is that we'll interface with something else such as OpenTSDB that'll do the long term storage, and we'll support seamlessly graphing across it. That's much easier to make reliable (just add a timeout), and if it does go down you'd still have the last few weeks of data sitting on the Prometheus box.

Doesn't OpenTSDB require zookeeper? So if your "network falls apart" you have no historical data? I guess thats fine if you're not alerting on data trends, and also have 10 minutes for your graphs to render.
fascinating!
Often forgotten is the incredible increase in drug consumption. Popular drugs like painkillers or antidepressants can have a significant effect on body weight. For the pharmaceutical industry it's like having a cake and eating it too: develop new drugs to fight weight gain, weight gain that can be caused by other drugs.

> Imagine, Java is run on your phone's SIM card. Enough?

Not Java, not even close. JavaCard is an extremely stripped-down version of Java. I've used it and it feels like C.

From https://en.wikipedia.org/wiki/Java_Card#Java_Card_vs._Java:

> However, many Java language features are not supported by Java Card (in particular types char, double, float and long; the transient qualifier; enums; arrays of more than one dimension; finalization; object cloning; threads). Further, some common features of Java are not provided at runtime by many actual smart cards (in particular type int, which is the default type of a Java expression; and garbage collection of objects).

[EDIT] But I am not arguing with the overarching argument that Java proper can run efficiently on very constrained devices. It all depends on the implementation.
