I'm not sneering at PowerShell because it's not Linux. And I think it's an impressive model. It's certainly a different way of doing things, and it's worth looking at and learning from.

But Powershell people dismiss the bash and Linux model of "everything's a file", too, the same way others dismiss the Powershell model. They're different; neither is "unquestionably" better for all cases.

Personally, once I start wanting stateful objects I can pass around to multiple methods, I switch from Bash to Python or Rust. I don't think Bash fits that use case well either, but that's not the only use case around.
Not only that, but cause and effect isn't obvious either. Let's say there's some correlation between high ratios of debt / gdp (our proxy for "unsutainable levels of debt") and low growth. Is the low growth caused by the high debt or did the country get into high debt because they've had low growth (and thus lower than expected revenues)?

If you thought we were already in a bubble, hang on to your seats, it's about to get much worse.
Yay! Thanks, updated. I hope to watch this later.
That says if you are doing 'easy work' you should drink 1/2 qt. per hour +/- 1/4 qt/h +/-1/4 qt per hour = 0-1 qts per hour depending on the person and conditions.

In other words it doesn't really say a lot especially for people who aren't soldiers marching in the sun.
Very cool project. Can you give us some more details about the hardware and software you're using?
He often makes those kind of comments. But he's schizophrenic, so it's probably not entirely his own fault.
They list what data they collect under the Windows section. They don't collect arbitrary files in personal folders.
You can turn Cortana off in Win10 too.
I don't think Win10 likely is doing so either.

As a child there is no bias as to 'oh it must be hard doing that because I am use to clicking X in Windows' they just learn stuff and get on with it. We should all remember to be like children sometimes. Explore ... not language wars!
Sorry I was trying to be pithy :)

jkimmel explained what beta is. The Tech industry as a whole has a high beta, and the smaller loss making component (i.e unicorns) an even higher beta. I am using the term beta loosely here as most of the unicorns are not public so they don’t really have a true beta, but they do have a pseudo-beta. They are being funded by private equity funds in what are effectively private IPOs.

The problem is that private equity funds are a high beta asset class. In times of risk aversion investors pull their money out of high risk asset classes and put them into lower risk asset classes like large public companies and bonds. Relatively small changes in investor preferences can get amplified up the investment chain resulting in large swings in demand at the far end.

A hypothetical example might be 10% of investors pull their money out of private equity funds, the funds find that most of their money is locked up in illiquid assets like loss making high growth tech companies (i.e. unicorns). In order to return the 10% of capital requested they have to cut new investments by 50%. The unicorns find that they are not able to raise the money they need to expand at the pace they have been and so go on a crash program to achieving profitability. They lay off developers, cut back on outside services, and stop buying small start-ups. VCs and angel investors seeing this cut back on investing stop putting money into new firms further decreasing demand. All of this is not good if you are running (or wanting to start) a business based on rapid growth that needs lots of capital.
I see meeting in person as a bad thing. The 2 times I've done it seems to be a fishing expedition where they get a ton of info from you, but every time you ask them a question they give a vague answer
Well, part of their strategy is to be able to much more rapidly design a wide variety of specialized parts, such as their ability to generate the specification computationally in 15 minutes. They recognize that the needs of the market are changing rapidly, and they have to be able to meet any of them.

Hopefully this lets them pivot and take advantage of new opportunities better than previous efforts to make a superior CPU.
Aha, yes in the prototyping stage that sort of immediate feedback would prove useful to converge upon the modeling necessary to properly translate the brush stroke pressure from the tablet into accurate saturation on the canvas. My comment was assuming that sort of translation was in place, but if you're discovering it then they would have to train the device. Which is an interesting thing, maybe apply machine learning to train the device much like how Andrew Ng and team trained that helicopter to fly upside down.
Commander Keen is indeed fun, but when you lose you have to start over from the beginning.
You can get good 1/32 drivers like the DRV8825 (https://www.pololu.com/product/2133) for not too much - I'm pretty confident they'll be able to do what you need (You can buy knockoffs for even cheaper). Even 1/16 is pretty dang smooth.

It also might be that you're supplying too much or too little current to the motors - both will result in jerkiness and noise. If your current drivers are current limiting, I'd look into tuning that. If they aren't, the ones I linked are.
While the author does refer to US music charts as a reference to past popularity, I don't see any indication that the Spotify data was US only.
> if we agree that being good at your career takes daily effort and practice for the majority of life, why does this conviction fall apart when it comes to diet and exercise?

This is how I put diet and exercise into perspective now. If I told someone I wanted to learn how to paint or play guitar and I started complaining in 2-3 weeks about how I'm seeing no progress, they would immediately be able to see how unrealistic I was with my initial expectations. Diet and exercise are no different.
I can perfectly understand why changes would not be wanted. It's no big deal at all.
That's said. The project vastly underestimates the impact the ESP8266 has had and will have. IMHO that chip and those that follow in its footsteps will revolutionize the industry in more ways than the 100 STM32 projects ever did. It's more like the Aduino viral like impact on hobbyists. As much as it's a flakey POS, it's not as pathetic as the ATMEL chips and I'm jumping on the bandwagon.
The US army specifically picks tall soldiers for the DMZ. I heard about it in the 70s.
Yeah, whichever - point being he should let us know where not to send our CVs.
Well someone has to be left holding the bag. I worry that done badly this will turn a generation off investing in tech start-ups.
Outstanding & thought-provoking, thank you.
It would be nice if I knew what LP meant.
Australia Post enveloped in startup war
In the short term, this is going to hurt even quality companies because investors, even very savvy VC's, always overcompensate for dramatic market shifts for some amount of time. But longer term I don't think we are going to see a repeat of 2000-2001. The reason is that the fundamentals are there.

Uber is a real business, as is Airbnb and several of the other unicorns. Real world businesses, small and large, buy advertising online, which means that companies like Snapchat and any other company that can grow a large audience cheaply have justifiable value as well. We live in a fundamentally different world than we did in the 2000's, so I am not too concerned (except if I were looking to raise capital in the next few months).

The People Who Get Their Own Gut Bacteria Fed Back to Them
Really, that's the only complaint I could make, it's quite lovely!
Powershell data is not just plain-text, it's all objects. On *nix when you run "ls -l" you get text. On powershell when you run "gci" you get objects. But the objects are nicely formatted automatically for you when they hit stdout so it ends up looking the same.

On powershell if I want to find a list of files that are more than 100k in size I can just do "gci | where Length -gt 100000". If I want to see the top 10 processes that have the most handles open I just run "get-process | sort handles -desc | select -first 10". That way of interacting with things extends all the way through every aspect of powershell and it's incredibly potent. If I want to query a bunch of build jobs from a service I can just create a simple couple line script that talks to a web service and returns queries. Then I can use the built in select, where, format, etc. commands to get at the data I want. I can filter by jobs that have failed, I can filter by jobs of a certain type, or that ran on one machine. All of that is basically free on powershell, it's just baked into the way everything works. It saves you from all the ridiculous overhead of using perl, sed, awk, etc. just to get at the data you want.

Aside from that, with powershell you get things like man-page-style help and usage messages, named parameters, parameter type checking, etc. at very low cost, as just the natural way of doing things.

The Unix philosophy has always been about having small tools that you can use together to get big stuff done, powershell very much embodies that philosophy.
This is pretty interesting because it raises the question about additional applications of this and similar alloys in the future. I wonder what, if any, material property drawbacks there are for the new alloy.
The US Supreme Court has ruled that any relationship between consenting adults is legal, and that any laws against the same are unconstitutional. (2003, Lawrence v Texas) This applied in this case to homosexuality, but the Supreme Court's ruling didn't limit the interpretation.

No politician wants to be the one who says "I propose a bill to make adultery legal. It's not an issue for the courts."
There have been less that a dozen misdemeanor prosecutions in the last half century in those 21 states combined.
So yes, in those states, it's illegal. Unconstitutionally so. Just as in many cases, so was homosexuality, and anal sex.
Yes this is right. The limited partners are the investors in VC funds who provide the money. The general partners are the VC’s who are supposed to have the experience be able to decide which companies are the good investments. It is a bit of a worry if LPs think that they can do this on their own. Maybe they can, but historically whenever “dumb money” enters a market a crash is not far away.
LPs are the investors from whom VCs raise their funds. The limitation they normally abide by, when investing through a partnership (like a VC), is that they aren't allowed to direct funds towards any particular investment.

So they can invest in a general thesis, but can't direct funds towards a specific company. The general partner (GP), typically an employee of the VC firm, manages the specific allocation of money into deals. The restriction to acting through a layer of management is a legal requirement in order to give the LPs the protections afforded by the LLP structure.
Some people like the convenience of not having to have to call/deal with someone every time.
> One Midwest LP who represents a family office and began receiving invitations to these affairs last year – one year after he began investing in privately held tech companies – has already backed a dozen startups out of YC. They represent one-third of his current portfolio of direct stakes.

> “I find [YC’s] batches are always the best of any accelerator class or demo day that I attend,” says the LP, who asked not to be named. “I’ve found a number of opportunities that were as exciting as any we’ve pursued.” YC’s endorsement, he says, is “a very important signal to us.”

An admittedly more cynical reading of this:

* Family office LP has very limited experience investing in privately-held tech companies.

* LP relies heavily on signals like "YC participant" because LP brings no unique investing insight to the table in this area.

The vast majority of LPs have no business investing directly in startups because they have no ability to add value to the individuals and institutions they represent, are incapable of performing adequate due diligence, and don't have the bandwidth or experience necessary to manage these kinds of investments.

Whether or not the current turmoil in the public markets is the start of something bigger or not, LPs itching to make direct investments strongly suggests that we are at or close to the peak in the current tech investment cycle.

I think if he was doing this for real (for profit) even than it would be questionable to target linux since its market penetration is pretty low while the effort to make you game running on linux is pretty big. I am saying this after spending some time trying to make a popular game running on linux. The lack of common API that _all_ of the linux distros support equally and easy to use for game developers does not help.

Valve stats on different platforms:

It shows an accumulated 0.89% market share for all the linux distros combined.
I sometimes wonder how many people in Europe are scared of additives because of the E-Number system that doesn't look natural at all and immediately makes you think that there are "chemicals" in your food. Who wants "E 300" in their food? Probably most random people you ask would say they don't want it without hesitation. Yet it's just Vitamin C.
While I don't doubt your mental narrative nor dismiss the value of evidence, if you think about the parent's assertion ("US and pop-culture bias") longer, it's obviously correct.

If you're aiming to deliver a new pitch in 15 seconds time you're not really alone in your own head, especially not if you're scanning the garden for hints and clues that might help you make small talk that stops that conversation from coming to a quick end. But of course, if you like being alone in your own head, nobody's stopping you from not knocking on those doors...

Agreed, introverted people can probably cope with selling popcorn on autopilot surprisingly easily if they don't have related issues with crowds or self-confidence. But is running round a stadium shouting at people the first thing the average teenage introvert thinks of as a fun way to make money, even in a pre-internet age?
YC is doing the VC job by curating and selecting good bets. LPs can go straight to these deals and avoid the middlemen. How is that going to affect the traditional LP > VC > startup model? Will LPs go straight to "top" accelerators and invest directly on these startups?
It's too bad that pearl jam isn't represented. I listened to some the other day and was taken with how good it was.

But, very interesting data nonetheless! I'm loving it!

Is it possible to filter the data by listener age? I wonder, because a lot of these songs are in play lists of mine from the 80s / 90s (I grew up in the 80s / 90s). Maybe spotify's user base is older than suspected?

Also, it would be interesting to plot billboard rankings vs spotify rankings. Possible?
Please don't worry. There will be no shortage of people who believe next time will be different. That's the beauty of the cycle. As you near the end, some subset of the people who swore they'd never be left holding the bag again become bag holders.
>> A vanishing middle-class is not healthy.

Yes, and?
I am more interested in what you use to make these graphs and charts. The data presentation in all the articles on poly-graph is always excellent. The interactive charts and graphs is perfect for letting the reader understand the data. Did you make all the graphs and charts?
No, the other one, Ferguson and Schimmel.
I'm actually shocked to see such a massive number of coders on HN (a skill that still somewhat eludes me) can't use the command line, which I consider a Step #0 type prerequisite.

It just hadn't even occurred to me that this might be a possibility. I'm not even sure how folks get started in the hobby/skill without the CLI background.

I'd be interested in hearing more about the skills progression of these folks, and how they got to the expertise they have today.

The hardware is http://www.makeblock.cc/xy-plotter-robot-kit/ sans electronics. I ended up purchasing the electronics anyways because they have a modified Arduino that uses RJ25, which makes the wiring much more stable (as opposed to pins stuck into an Arduino).

If you got the individual pieces yourself or 3D printed it can be much cheaper.

The main electrical components are:

1 x Arduino Uno (I used the modified Uno called "Orion" that has RJ2 ports)
2 x Stepper motors
1 x Servo motor
4 x microswitches as limit switches
2 x stepper motor drivers (they handle the microstepping)
3 x RJ25 breakout boards (for connecting the limit switches to RJ25 ports)

This was a prototype to prove the concept. I'm going to experiment with 3D printed parts next in a new design.

If you're feeding in coordinates as Gcode I would recommend loading Grbl. Keep in mind Grbl has specific pin requirements that make it incompatible with the Orion's RJ25 ports, so you'd have to wire a normal Arduino. Makeblock supplies Gcode firmware that works with the Orion.

For the demo in the video, the firmware was custom to handle real-time input and recording of motion.

On the host computer side, it was just a python script that interfaced with the Wacom tablet. Specifically: https://bitbucket.org/AnomalousUnderdog/pythonmactabletlib

"Women admit to cheating less than men, and this is reflected in a bias of studies whose methodology includes self-reporting."

I remember reading something that said something along the lines of "A married man in a bar, cheating, is more likely to do so without thought to the wedding ring - either oblivious to taking it off or apathetic".

Women doing the same thing were much more likely to make a conscious point of removing the wedding ring in the same situation.

Thinking back to my own learning curve, I'm not sure if a linter would be helpful or harmful. On the one hand, it makes him think about the little details, on the other hand, not having to think about it frees him up to move on to thinking about bigger things.
My intuition is that indentation is more readily apparent. You can tell that a group of lines or an individual line is indented or not at a glance. It's natural to see that they are grouped. With braces, you have to search for the opening and closing brace, and furthermore you must search within those braces to ensure another brace set isn't being opened, in case you missed one. You have to learn both -- about how to designate a set of statements as grouped using opening and closing braces, and how to detect a common class of errors related to nesting braces.
You are correct, but... do you think that anyone on Hacker News wants to just learn what has come before, and add nothing new to the world?
Yes but the LPs can hold the bag. Misquoting Joseph Kennedy when the shoe shine boy gives you stock advice then it is time to sell.

On this topic I spoke to my agent in China about the Chinese stock market back in May when it was going straight up. He told me that all the waiters were talking amongst themselves about what stock to buy, etc.
I know, anything even remotely non-permabull is nuked for bad feels about The Strongest Economy In Years.

Alright, as a fellow traveller, let me help you. I'm going to make some observations and then give you my magic key to dealing with this market:

- Picking individual stocks is very difficult unless you are Buffett-tier

- The low-cost index funders have a very strong argument

- That being said, there are obvious long term momentum trends in the broad market, the efficient market guys are a joke

- Daily and even weekly movements have too much noise to be worth looking at

- Monthly is actually pretty good though

- Sitting in cash for any extended period is almost impossible for most investors and flat out impossible for funds (competitive advantage alert!)

So, putting that all together, you have the following thought:

"What if do index investing and I use momentum measurements of the broad market on a monthly basis to try to avoid the shit-show pullbacks."

I use the monthly MACD of the S&P 500, and it has worked very well: invest when MACD is positive, get more conservative as it goes to zero, start selling when it goes negative, sit in cash and wait for the faster moving average to reverse on a monthly basis.

No one believes me, and you shouldn't either. But there it is.

The answer (pains me to say it) is, if anything, government spending.

That's not something the Fed can do.

That's something Congress can (in theory) do, but hasn't shown much interest in doing.

> We have come to depend far too much on monetary stimulus relative to fiscal stimulus.

I don't think anyone has a preference for monetary stimulus so much as the fact that the only place where there are sufficient people with interest in stimulus to effect anything is at the Fed, where the only lever they have is monetary stimulus.
Grobyk – YCF declined
In reality, if you're using a machine that's owned by your employer, you should always assume that everything you do is being monitored at all times, regardless of what operating system said machine is running, because chances are in favor of that being the case. Expect at the absolute least some sort of web traffic monitoring (probably via a corporate proxy); in some cases, I've seen companies install keyloggers (and, in fact, this is the "legitimate" use case for keyloggers, remote administration tools, etc.).

You should also expect that any mobile device accessing company resources (including - and especially - email) is effectively giving your employer root access. This is almost certainly the case if you use a mobile device with Microsoft Exchange.

In other words, in the context of employee workstations, Microsoft's spying is effectively a non-factor for employee privacy.

Now of course, this is all describing intra-organizational surveillance. Microsoft's data collection is inter-organizational, which has rather significant implications for healthcare organizations (since now Microsoft is the single-point-of-failure for a HIPAA breach), financial institutions, law firms, the works. That's all a bit of a digression from the point of children being automatically spied on, however.

I agree with the parent poster that the article is US pop-culture centric. I just wanted to point out that the data isn't, necessarily, strictly US specific. I also felt that that the parent comment was a bit snarky given that this website has a large US audience, and US music and pop-culture are popular around the world.
