I think these headlines promoting exercise for long term benefits might do more harm than good, people have a hard time doing things for super delayed gratification.

I exercise because the immediate effects are evident on my mood and wakefulness. It just feels good to exercise. The first couple of weeks/months consistently going to the gym maybe took some more discipline, because everything feels weird at first. The elliptical. These machine contraptions. It's unfamiliar. But once you're used to it, it's smooth sailing. You don't have to be so strict about it...just do it until you're comfortable and then go when you feel like it.

Another note, keep in mind it is MUCH easier to maintain fitness than to build it. When it comes to weight training, I was serious about it for a couple of years following a plan I found online. Since then, I lift weights a few times a month and have mostly maintained the strength/appearance from the time of consistency.

I had the same problem until I got into MMA. I'm not a stereotypical MMA "bro" but the social aspects and the varied but intense workouts are perfect for me to be engaged and not lose interest. Plus learning to fight is a skill even if I hope to never have to use it in a serious situation.
If you have a typical STEM job or better, your employer covers nearly all the cost of healthcare for your family.

You only need private schooling if you are in a city and don't have a stay-at-home parent. Suburban schools are usually OK. You can homeschool.

In most states, you don't need a college tuition fund. For example, a student in my state can get an AA degree for about $5000, and can then upgrade it to a BS degree for an additional $15000. If you birth a kid every 2 years, you'll end up with 2 kids in college at once and the cost will be $10000 per year. That is 1/6 of a typical family income, or about 1/12 of a typical STEM job.

> you should be very suspicious of any conclusion that requires you to assume that all the world’s experts have missed something extremely basic.

This is hugely mistaken. If you're an expert in compliance in one field, often your insights are valid in another field.

For example, anybody who has certified a data center knows that Fukushima was both in the wrong location and had wonky power distribution.

Anybody in aviation knows the Tyndall F-22s were in the wrong location after Kermit Weeks' collection was destroyed in Florida in 1990.

Expertise and common sense are always in short supply. It's 2018 - we've collected enough hindsight for the next 100 years.
Hacker News is BTC’s biotch
No, but over the past 50 years, we’ve had two severe nuclear incidents resulting in any kind of long-term environmental damage (Fukuhima and Chernobyl), and Fukushima will be remediated within a decade.

In the mean time, we’ve had Exxon Valdez, Deepwater Horizon, Andover, San Carlos, CA, plus oil trains burning down entire towns, coal mine explosions, two Gulf Wars, and sea level rise due to global warming.

Pick your poison.
Thanks. I love how practical your advice is. Going to do this tomorrow. Maybe it'll even help align my sleep schedule. My wife is up at 6 and I always sleep in to 8.

Beat Saber looks just so snappy and catchy.
A's belief that their ideology is broad and that B's is narrow and uniform, is in fact part of what defines A's rhetoric and its viewpoint of itself and of B. But the fact remains that A's tolerance for B is no higher than B's tolerance for A. A freaks out just as theatrically when it loses an election as B does when it does. Each one is starting to define itself as not the other one. A = !B and B = !A. Neither has a coherent ideology anymore. You are voting for nothing. The differences are now chiefly historical, between the ideologies each sold out and neither implements.
Early Rust was much closer to Erlang, but it lost more and more of it over time.
When did you last try it? It's improved a lot recently. E.g. upgrading a lot of apps now requires only a single tap; you don't have to download/install/confirm install each one manually.
Boy did I enjoy that! Beyond the enjoyable tale of his love of steel and how it has influenced his life, reading between the lines you can see just how being from certain backgrounds can really make a path like this challenging. He had challenges from both an upbringing perspective (didn't know what the GRE was, sort of randomly chose colleges initially, etc.) as well as from an education perspective (the challenges of smaller/weaker schools, the value of good teachers such as Mr. Bowler also see http://www.equality-of-opportunity.org/assets/documents/teac...)
The other difference is that a true Ponzi scheme is fundamentally unsustainable, whereas social security is not. It may need adjustments, it’s not like you have exponentially growing divergence.

It's a value choice you are making, and "financial reasons" probably have little to do with it. The money issue is an excuse.

Europe generally has the paid parental leave and universal healthcare. Some parts even have the free college tuition. Where are the kids?

People who focus on families don't need paid parental leave. There is a full-time parent permanently at home. Not that everybody needs to go to college, but that is often cheap if you start with a community college AA degree and then transfer to a state school. Most people don't have much of a healthcare problem.

Pullups are more of a gymnastic activity that just requires your nervous system is trained to recruit the right muscles very intensely at the right time. I can do maybe 12-15 and am borderline overweight, just because I do them habitually.
In addition to what everyone is saying, you might be exercising too hard. The fitness industry, paradoxically, pushes the idea that exercise should be hard, perhaps because it’s an easy thing for people to believe. Hard work feels like it’s getting you in shape.

But most cardio should be easy, like 60-70% your training maximum heart rate. Many elite distance runners follow an “80/20” rule, where 80% of their training is easy in this way. But 100% is fine also. If you’re not used to it, this feels odd, like you’re going too slow and doing nothing. But measure your time and distance and the improvements will be obvious. It’s like training for free. The only ingredient is time. After a good long low-intensity run I feel less fatigued than I did when I started. Meanwhile hordes of people suffer through these awful spinning classes. It’s like they think exercise should make you feel worse instead of better!

People who feel the need to put in effort and who aren’t distance athletes are likely much better served by adding HIIT and/or strength training than by pushing steady-state cardio too hard.
Payments should be client controlled. Rather than you giving online organizations your payment information, they should request payments from you and you could manually approve or reject them. You could give certain trusted organizations you trust an auto accept option (for instance monthly web hosting bills).

I think the quality of someone's childhood and subsequent life is partly determined by siblings. Even the miserable times with siblings, such as childhood fights, are teaching you. Later in life you have long-term connections with other human beings. These connections will likely survive even across career changes and long-distance relocation.

Compressed air can be released back into the atmosphere from which it came without much danger, but gas is not so harmless. Relief valves exist to prevent pipes from exploding due to the pressure, and during this incident they were probably wide open, but they just continued to release gas which eventually exploded anyway.
Sexy hot babe gets double penetrated
I got into running, thinking that I wanted to try for a half-marathon. I actually worked up to the distance surprisingly quickly. I was under 30 at the time and it took like 2 months, and before that I wasn't running at all or doing any other exercise regularly. I started having some knee pain (flat feet don't help) and stopped after it became painful to run even a mile or two. About a year later, I fell on a skateboard on the same knee and injured my bursae. I fear that my running days are over, but it was kind of fun in a weird way after you get past ~mile 4. I still go mountain biking occasionally and enjoy long walks (on vacation I'll walk 15+ miles in a day).
apt-get dist-upgrade takes several hours on my Linux partition, which I also boot just a few times per year.

Ubuntu also completely blows itself up into an unbootable state at least once a year after updates.

Windows Update and testing suck, but Linux package management and upgrading suck just as badly. Systemd upgrade bugs seem to cause the most un-bootable systems in my experience, with alarming frequency, even on LTS servers that see little churn.

you can read about some simple rotating systems that, in some sense, end up reversed after a 360 degree rotation amd require another 360 to turn fully around. The article above has a nifty gif of this.

Formally, this kind of thing is studied using what are called spinors and gets used a lot in quantum mechanics and friends when talking about quantum spin. Behind the scenes these are described using things called spinors.

As it turns out, quaternions (and octonions) are capable of describing such things while simple rotations of any kind are insufficient. There are deep connections between spinors of different dimensions and the quaternions/octonions. For those interested, the term here is "Bott periodicity".
If one looks here,

> Total expenditures in 2014 were $859 billion. Total income was $884 billion, which consisted of $786 billion in non-interest income and $98 billion in interest earnings. Asset reserves held in special issue U.S. Treasury securities grew from $2,764 billion at the beginning of the year to $2,789 billion at the end of the year.

This is not in any shape or form a ponzi scheme.
> Whoever is higher on the dominance hierarchy gets to subject others to their opinions.

That's a bizarre statement in the modern world. In the modern world, we vote on whose opinion carries the day, and that is only in the unusual cases where government has power in the matter (because we have freedom and civil rights).

Fixed: “67% of workers earning over $100k see themselves “changing jobs for better pay due to strong labor market” in the next 6 months.”
Big company. Stable paycheck will change your life for the better.

Once you have a nest egg of 100k USD or so, you can weather pretty much any storm and can accept riskier employment.
Do you mind on elaborating on that? Any nice books or tutorials you've seen on the subject?
A big part of his argument is that it's not, in fact, an important idea.
Got out 5 years ago and headed south - was the best decision I've ever made. It wasn't until I left that I realized just how economically backwards and dysfunctional the region (and state) was. I remain dubious about the city's prospect at regained glory.

But I applaud those who stick around and think well of the city and the tri-county area, and who fight the good fight to improve it. I wish them better luck and fortune than those that preceded them in the prior 50 years.
This is fantastic! I started doing webwork a few years back and while I've gotten a chance to do some cool projects, streaming wasn't there.
Because if they admitted it it would hurt public image right?

Why did I write a k-means to cluster images
I also enjoy mountain biking, but not as much in California. I grew up in the midwest, and while there were many more mosquitoes there and the weather sucked half of the year, the trails were a lot more fun IMO. It was much flatter, so you could build up a lot more speed and basically push up the small hills without losing much momentum. Mountain biking in NorCal is much more 30-90 minutes of climbing followed by 5-15 minutes of downhill where you're dodging hikers, other bikers, horses, and dog poop. The sun is also pretty brutal, with not much cover aside from a few trail networks, whereas in the midwest most MTB trails were 90% in a forest.

It can still be fun, but honestly it makes me want an e-bike to get past the boring grindey up-hill parts. The other aspect of this is that in the midwest, once you had attained a certain level of mountain biking proficiency / fitness, you could go fast on trails all of the time, because you'd be able to sprint up the hills, pump any bumps / logs, and pedal down hills as well. It was much more of a "roller coaster" experience. In NorCal, even if you're super fit, you might be able to get up hills more quickly, but no one is sprinting multi-mile climbs at ~15mph. Again, e-bike, but they're super expensive for a nice one and they're only allowed on a few trails out here AFAIK.

> I see older people who did nothing to take care of themselves doing just fine, and plenty of fit people whose health is surprisingly bad

You may be older, but your viewpoint seems surprisingly immature. Unless you've kept careful records, it's likely that you feel this way because your brain has lived the surprising counterexamples, not because people don't have control over their health outcomes. Genetics obviously play a role, but until those can be changed, you can choose to work with the tools you have or opt out of the game.

I think there’s also something else at play. Most of my friends also don’t believe for a second that a corporation has their best interests at heart. It’s not just promotions — it’s work life balance, it’s top-down decision making and political empire building, re-orgs every 4-6 months. The growth at all costs style of building companies chews employees up and spits them out.
Honestly GORN is a great workout as well, but you run into issues with the Oculus getting too hot on your sweaty face. I picked up a "VR Cover" and it helps a bit, but it still gets soaked through with sweat. It is at least easier to wash.
I've been practicing Ving Tsun for around 25 years. Many aren't aware, but the most of the system is based on blades. The issue I've been having is finding good enough knives to train with. Most of the stuff out there is ornamental crap that will teach you the wrong thing best case and break and hurt someone if you're unlucky. I ended up getting two big, well balanced hunting knives that I've blunted for training.

I'm pretty sure I'll end up making my own sooner or later...
I had believed such a catastrophe was all but impossible. The natural gas industry has many troubles, including chronic leaks that release millions of tons of methane into the atmosphere, but I had thought that pressure regulation was a solved problem.

Yeah, natural gas tech is old and over time has been worked into a multi-layer system that is close to "inherently safe". I remember years ago trying to light an old heater the most stupid way possible and only singeing my eyebrows in the resulting explosion.

But these events just show that if a company skimps enough on needed maintenance, ignoring constant smaller leaks and the similar despicable maneuvers done by this gas company, then the overall potential of piping an explosive gas into a city can be realized and people die and are injured, building are destroyed and so-forth.

In this context, it seems pretty obvious this isn't a "technological tragedy" but a "people doing bad things tragedy" and I hope it's obvious people deserve to go to jail for this and if they don't then other problematic aspect of this society are then to blame.
The MacBook Air is still pretty reasonable. I thought moving from my 15” MBP would make it seem way too small but so far it’s been stellar and far more portable. Got a 2TB external SSD and run a lot from that (VMs).
In mathematics often proofs lead to understanding why something works (on the other hand, many proofs aren’t written in a way that make the main ideas clear or easy to tease out from details)
"The reason people are quitting today is because the labor market is so competitive that the only way they can get a significant increase in income is by quitting and going to another job."

Well, no, the opposite is true. Employees have to quit because companies stubbornly refuse to be competitive on salary.

The reason for that is mismanagement - managers and HR would be personally criticized for "being soft" if they offered raises, regardless of the benefits to the company of doing so.
That's not comparable. Fukushima's failure was due to fairly basic and straightforward precautions being in error or missing entirely. In other words they were avoidable, known knowns. In contrast we do not actually know how to achieve a breakthrough in quantum error correction except through the normal course of research. We don't just have known unknowns presenting obstacles to the path forward, we have unknown unknowns which must be resolved before further breakthroughs can be achieved.

For that reason postulating when and how we'll have a giant leap forward in quantum error correction is closer to thinking about how to resolve the Riemann Hypothesis or Navier-Stokes, or when a deadly asteroid might finally be on a collision path with Earth. It's reasonable to be concerned about quantum computing's risk to cryptography, but it's infeasible to productively model whether or not we'll suddenly jump forwards by decades in research time.

To state this another way: if the most informed thing you can state about the likelihood of an event is that it could happen, it's probably not feasible to model the likelihood of that event in a way that makes risk assessment productive.
That was a great read. I really admire people having passion as well as expertise in these unique fields. Once fortune 500 CEO had come to my school for talk and he told us shortest path to rise up in corporate ladder is either having expertise in somewhat niche but valuable field or starting your own successful company or having great amount of luck (which he said most C level folks don't say out publicly)
Aaaaah. Memories.

For anyone worried about knee injuries from running, or shin splints I can highly recommend weightlifting, in particular squats, as an auxiliary exercise. I kept on running, getting pains in my knees and resting for two weeks and then just doing it again. After six months (way longer than probably necessary) of progressively lifting higher weights I went back to running and I’m doing my first 50K next week, having done a 35K up and down mountains previously. My first run after the long period weightlifting I just decided to run a half marathon distance to see if I could. The muscle pain the next day was less than I often get from lifting.

Yeah, one thing that world travel has really shown me is how dumb US cities and infrastructure are. In the UK, Japan, Hong Kong, etc, you can take trains wherever you want to go and walk on both ends to make up the last 1/4 mile. All of those 1/4 miles add up to a decent workout, and it's great to not have to buy + maintain + drive + park a vehicle.

I'm still mad at everyone who had a hand in preventing BART from running down the peninsula. https://io9.gizmodo.com/5866928/a-map-of-san-franciscos-subw... has the original map if you haven't seen it. It would have ran from Jennings (north of Santa Rosa in the far north bay) all the way down to Los Gatos (in the Santa Cruz foothills), crossed the South Bay at 3 points (Oakland, Foster City, and East Palo Alto), and featured MANY more routes inside of San Francisco proper to places like Presidio, North Beach, Masonic, Van Ness, Castro, Oyster Point, Taravel, and Potrero Hill. I know that a couple of those routes are now served by MUNI trains, but this was a plan in 1956, would have been a single system, and still had way better coverage than we have today or planned in the next 20 years.
NNs are not binary -- they're fundamentally analog, so for classification problems, they produce probabilities that a test case is in each possible class.

I think that's "true and false". Yes, NNs produce a "chance of being X" but no, NNs don't naturally produce a human-intuitive "degree of being X". If the NN is looking for a "red fire engine", it's not necessarily going to produce "degree of redness" as its output.

-- As to neural nets representing many functions; neural nets, Taylor series, Fourier series and so-forth can represent/approximate "any function". True but effectively irrelevant. What matters is what function a given methodology can be trained, programmed or whatever into representing.

This is essentially a "job market paper" for a data science bootcamp for recent PhDs.

The contents are nothing groundbreaking but just an exploration of how different models and data sources can be used to predict something. Insofar as the purpose is to demonstrate the author could do the same sort of analysis about questions like will customers buy your product based on unstructured reviews posted on amazon, I think its successful.

The only problematic aspect seems to be the notion that you can "recommend" a form of birth control based on modeling preferences. This is definitely a Jurassic Park type of article, interesting because it's so clear that data science built on self reported information on reddit is a bad way to actually recommend options when there are much better method available (e.g. professionals).
