I would have been a 4th generation RR employee, if the RR hadn't gone bankrupt. Got to spend all kinds of time as a kid in rail yards going stuff that would probably be illegal for everyone involved now a days. This is before CCTV everywhere and extensive tracking. Anyway I'll try to match up first post comment/question with second post correct answer, if this reformat helps:

Torque is higher at low speeds - No, with "modern" say post 1960 diesel-electric locos its constant. Or more accurately current limited to a max which is achievable at almost any reasonable low speed condition. Maybe a car analogy is all locos can "spin their tires" under any condition up to 45 MPH or so. There are no "econobox locomotives" or the equivalent.

Peculiar spherical cow assumptions about no-slip conditions - No, its very complicated and as you'd suspect lots of anti-lock anti-skid technology actually started on trains before it went to cars, and trains are always slipping a little (not very much, and the optimum is not exactly zero just close to it)

Slack is an intentional mfgr tolerance thing - No its something that could (almost) be eliminated and is a huge PITA under certain operating conditions. Its goal zero not goal 0.1% by design or whatever.

Theoretically the bearings must be pretty good - yes indeed they are, awesome roller bearings required by regulation since the 60s

If you provide specific examples of what doesn't make sense it would be possible to expand upon that specific topic.
The problem is that hiring/firing employees is expensive. Hiring only super-motivated people who need no supervision is highly unrealistic. Even really smart people often can be lazy and only do what is necessary to get by.

supply and demand have an important quality called elasticity, which is not taken into account in libertarian discourse.

unlike a simple commodity market, like coffee for example, where a buyer can say "these prices are too high, i'm not going to buy any", a worker cannot simply say, "these wages are too low, i'm not going to work". (unless the government plans to give them all sufficient social security so that they can live comfortably without any work, which is unlikely and probably undesirable.)

likewise, when a coffee producer sells a lot due to good prices, he will increase his production, and thus the supply. in the labor market, a company that seeks workers and offers them a great wage will easily find workers, but i find it incredible that it's managers will then think "hey, we had such a great demand for work, let's hire more people just because of that!" it will not increase demand, limiting the effect a single positive agent can have.

not every market is exactly the same, and considering the dynamics of various markets will enable you to understand why so many countries have minimum wage, why they subsidize food production and are very interested in influencing the prices of basic commodities, and why they often meddle in real estate. these are things people simply cannot do without, and the stability of governments and regimes depends on somehow ensuring them for as many people as possible.
"It starts out as fun, a game in pre-school, but then..."

For some of us (like me a few other subjects that I remember) the conforming game was never fun. To force someone to wake up and then to sync to an activity program, and then to sleep some programmed hours, and so on... it was necessary maybe, but I never recall it to be felt as "fun".
The slack action from a mile-long train is one of the most awe-inspiring, bone-jarring manifestations of raw power I have ever experienced. The first time I felt it, it established in my mind the idea that freight trains are forces of nature rather than vehicles.

Passenger trains also experience it (though the gear on these trains are slightly stiffer), but those cars are designed to have a much smoother ride, and they are also much shorter (8-10 cars instead of 80-100+). On a long train, it sounds like thunder coming from the front, and then a split second later the entire world shakes.
>If we have evidence that something isn't true

Except you don't. A guy who eats all of the time and is skinny has a high metabolism. That's still 'calories in' < 'calories out'. The reason it's being called 'confusion' is because someone has made the mistake of thinking 'calories in' = 'weight'.

>By the way, no one, anywhere, is disputing the laws of thermodynamics when they say that "calories in / calories out" isn't the whole story

That's precisely what they are doing. Metabolism, poor calorie absorption, exercise, etc all fall under 'calories out'. It is the whole story, it just doesn't provide a lot of useful details about how to boost the 'calories out' category.
I've been compiling libguestfs, libvirt, the kernel, qemu, and other programs, and using the aarch64 machine interactively, and it certainly doesn't feel slow.

I have to be careful about exactly what I say here because the NDA prevents me from doing any kind of performance benchmarking (for good reasons: this is pre-release hardware and the performance doesn't reflect what the final hardware will be capable of), but ... performance is fine, I've had no problem with either single-threaded tasks or parallel compiles. Given I'm using it as a remote machine over ssh, it doesn't "feel" any different from an x86-64 server.

> The map you see is the Mercator projection.

> But I've often wondered what lies beyond those cut-offs... to make a map that didn't cut off but simply kept going. As the distortion progresses towards infinity, you would eventually reach the scale of cities, houses, insects, atoms...

> But of course that'd all be on a featureless expanse of ice. No map service even publishes image tiles for such extreme latitudes.

> To make things actually interesting, we must artifically shift the pole of the project to a more interesting place. Imagine the earth encased by a rigid cage of latitude and longitude lines. We rotate the earth while leaving the cage fixed until a new point of interest has taken the place of the North Pole.

> This is called an oblique Mercator, and is normally used to shift an area of interest onto the equator of the map to avoid distortion. But whereas others avoid distortion, we embrace it.

> Note how strange the oblique Mercator looks even without the increased cutoffs. The standard Mercator is so ingrained in the public consciousness that we perceive it as 'normal'. But once you shift the pole its ubiquitous distortion is laid bare.

> Lastly, increasing the cutoffs produces a map much taller than it is wide. So it is presented sideways here for easier viewing. (set the pole to the North Pole like usual to see this most clearly)
While we are at it, we can tell modern religious literalists that 'Baal' means Lord, and that El and YHVH are different Gods as well, and that all three once competed for followers.
Welcome to OpenStreetMap, Telangana
While this may not be in a easily workable state right now, this is really awesome, now people can run their own clouds even easier. This removes some of the value-add (and associated costs) of various VPS providers and cloud offerings.

I currently manage one VPS that hosts multiple sites/apps that I work on, and it's not the worst thing ever, but it could be easier. Right now I still SSH in and restart services by hand, but a web interface would make that much easier to manage.

If they allow for extensible plugins, we could see an explosion of nagios-like functionality being developed, as well as even better free server monitoring resources.

Really looking forward to seeing this progress

I'd see you as a bit misguided then. Different than Linux != more secure. The best way would be isolation using hardware's VT functionality. That enforced separation at the hardware level. Something more like this. Also, the xen microkernel is very small in comparison to Linux and easier to audit.

I've had the same experience where I've been downvoted because my comment goes against the prevailing group-think of the site. This has a chilling effect on contribution of new ideas to comments, which thereby reinforces the group-think. It's a vicious cycle. I'm very hesitant to post comments now for fear that they will be downvoted for no good reason.
Are you plugged into the W'loo community? Any intros or tips on how to get started? Sadly, I'm a UofT alum - when I looked at the programs at Waterloo, they seemed focused on their students.
"Unlimited time off" is the new open office plan. An idea that seems liberating, but will be despised 10 years on.

These policies are BS, what they really are is the unlimited right to negotiate for vacation time. They are also frequently chosen because they mean employers don't need to cut employees a check for vacation time not taken when they leave. When I left my last job which had this policy I asked for a check for vacation not taken, and was told that one reason they chose that policy was that they wouldn't have to cut such checks.

Any reasonable employer can make exceptions to a fixed vacation policy for things like sick leave, if an employee gets layed up for a month after a car wreck they can choose to pay them despite the policy.

Either type of policy can be interpreted generously or not, but with fixed vacation policies there are at least limits on how poorly you can be treated, and you know it up front.
I'm all for flexible vacation / time off - that's how my department works, and it's been great. Flexible hours are highly dependent on the nature of your employees' work, though. Some jobs require you to be in the office when everyone else is in the office for calls, meetings, emails, etc. My wife's employer technically allows flexible work hours, but most people gravitate toward 9-6 because they usually need to be available to each other.
I think that it's supposed to demonstrate how inaccurate the Mercator projection (the one that's used on Google Maps) is at conveying relative size of continents. For example, Greenland looks enormous whereas it's actually quite small, while Africa looks much smaller than it is in reality.

Google uses this projection because it's best at preserving angles and shapes.
Can you provide some context for this link?
I looked on LinkedIn to see how many employees Mindsense has; the answer was 1-10 (perhaps that's right, perhaps it's wrong, but it's probably in the right ballpark). I'm sure their policy of "0 vacation days. 0 sick days. 0 holidays" works at that scale, where everyone is some sort of lynchpin product manager with a vested interest in the business, but the reality is that, in a larger organisation, there will inevitably be people who are not massively focused on the work at hand, and who treat their job, really, as a means to an end - a way of passing some time between the hours of 9am and 5pm in order to generate enough money to pay their bills and save up for some holidays that they actually enjoy.

For a significant portion of those people, offering that kind of flexibility would be a disaster, because they would see it as carte blanche to do as little as they could possibly get away with doing, with as many days sick or on holiday/vacation as they liked. These people aren't motivated by the work they're doing, in any meaningful sense, and they would just as well not be doing it at all if that option were presented to them.

Sure, you could say "don't hire those people", but larger organisations need lots of bodies to fill often quite dull jobs, and you can't really afford to treat those people "as adults", whatever that means.
Hahaha, will do my best!
With SNI do you still need one certificate for each subdomain?
Yes, Mavericks started using SMB2 which has many reported performance issues [0]. Most people experiencing it can work around this by using cifs:// instead of smb:// or disabling SMB2 and reverting to using SMB1 [1].

Heh, compared to prices back in the day (2000~) the current prices are extremely competitive.

I remember breaking a piggy bank to secure a single domain back then, it was around $99+.

Then dropped to $49.99 and now it's $9.99.

Indeed. I was talking to my lawyer about having a no vacation policy policy, and he said I would need to set a mandatory minimum vacation, and make sure employees take a certain number of days off.

His case in point example was me. He pointed out that I work all the time and never take proper vacations (I just had my first one in over two years, and even that was half devoted to a startup conference).

What do they add to the community, other than flames and at least half-a-frontpageful of uninteresting articles about (Apple|Google|Microsoft|otherbigtechcorp) doing this and that? These are the articles that you'd find in any mainstream tech media anyway. These also tend to generate too much opinions (it's easy to have one) without so much deep thought and technical discussion. Maybe my memory is hazy but I think HN was really quite different back when I first got interested in it.

To be super-pedantic (because the topic is interesting), a little spin is good for an automobile. Rubber friction is a combination of adhesion, mechanical deformation, and wear.[1] In order to maximize traction with a tire you will have some optimal slip, increasing the "wear" component beyond what is seen in "normal" driving conditions. Of course, too much sliding/wheelspin and you reduce the other components. It's a balance that depends on rubber compounds, tire construction, and road conditions.

Yeah, it's the global resources that are the biggest problem, though. Certainly, if you can namespace everything, then the code itself won't fall over. If you version the URL in Go, you can do that too. Stuff that uses v1 can live along side the stuff that uses 1.1. THey won't be compatible in that you can't pass a v1.Foo into something that wants a v1.1.Foo... but that's not a good idea anyway.
OMG, that sounds like where I work.

It's acceptable to skip a few of the meetings after things inevitably turn into a cluster bomb and somebody has to start writing the actual code.

Also the reasoning is you can derail a collection of (relatively) lightweight cars by pushing behind them with a very heavy engine, but its much harder to derail by pulling.

Think of trying to keep a rope straight by pulling on it, vs trying to keep a rope straight by pushing on it.

The passenger train rule is because its hard to kill people by tipping over coal cars especially when its a rare failure mode anyway. But you wouldn't risk it with cars full of passengers.

(Oh and edited to add WRT switches, its subjectively 10 to 100 times harder to derail on a switch going one direction than the other, so again you'd risk backing a bunch of coal cars thru a switch but it would be pretty dumb to do it with cars full of passengers)

A few years ago you might also ask why would anyone give out $5 certificates? It's not any more work on their part - it's a extra parameter sent to their certificate generator.

I'd like to plug the policy my friend's startup is using. Unlimited vacation plus mandatory vacation. https://sourcegraph.com/blog/mandatory-vacation

I think this strikes a good balance of establishing a culture of taking vacation while allowing people to take off the time they need.
There are many programming languages that in practice tend to be locked to one platform or another. C# isn't only on Windows and Objective-C isn't only on iOS, but very few people learn either of those languages with the expectation of "write once, run anywhere." (I've found that generally people who use C# on other platforms do so because they already know C# and don't want to learn something else.)

On principle I'd like to see Apple put Swift under a free software license of some kind and ideally make a cross-platform reference implementation, but realistically, even if they do that it's unlikely to ever get wide use anywhere but Apple products.
Yes. SNI just allows you to have multiple SSL certificates per server IP address.
The revocation fee that everyone had to pay after heartbleed could be described as bullshit.
> They actually have a few well defined corridors and altitudes in which they can operate - the straight lines drawn from one VOR (effectively equivalent to a major airport) to another at 1,000 foot intervals.

Until NextGen (ADS, etc) finishes its rollout and everyone flies direct instead of on Victor airways and VOR to VOR.
This is pretty cool. Could it run on something like an Arduino?
I remember Apple representatives promising to a room full of CERN researchers that the JavaBridge wasn't going away and how Java was a first class language for Mac OS X development.
Yep, costs some money to revoke, and in light of heartbleed, they probably made some money. But I like the fact I can re-issue unlimited certificates forever, and pay for revocation only when the rare heartbleed-like vulnerability happens.

Thanks, now I have that song in my head! :-) very funny!
Perhaps such a ruthless track is beneficial to Matt, and if so I bid him good fortune. It would be of terrible hindrance to my own productivity, though. I am at heart a social person. I require a balance of social interaction and thoughtful solitude to be at my best.

Too much social interaction can overload me with many extra thoughts and ideas that tend to mish-mash together in my brain and become nothing but flights of fancy.

On the other hand, too much solitude has a detrimental effect on my focus. Not only do I start to feel a bit down, but I find that without that social outlet I will concentrate too much on details that may not even be relevant to my current task (or even to the project as a whole).

Given a good (reasonable) dose of social interaction, I find my focus gets into a groove and tasks are just easier to complete, regardless of possible interruption by colleagues.

Everyone must find their own balance. I suspect that Matt and I sit on opposite sides of this particular range, or are at least a fair distance apart.
Some people are uncomfortable talking about money. Others are uncomfortable talking about vacation time. I think it helps to have some sort of loose policy, because people are so different. I watched a situation where there were 3 people doing the same role. One had seniority, took a lot of time off to travel (some of this unpaid) and the other two were left dealing with the extra workload.

It's hard to have a non-policy policy because people are so different.

I do agree with the article though, because I feel like the 8 hours a day, 5 days a week "norm" for knowledge workers is kind of silly. You're probably getting 5 hours a day of really productive time. The other 3 hours they are banking/scheduling/handling the business of life or taking a mental break.

Factory shift work is probably better suited to the structure described, but that work is quickly becoming extinct.

The key point in the article is that you have to talk about it openly, and don't shame people in to not taking time off.

Sometimes (especially with client facing roles) sound judgement is the most important characteristic of an employee. If they don't get mental breaks every few months, they might show poor judgement.
suddenly this post disappeared from HN first few pages?
As a Lyft driver, I am more productive the more hours I work (I top out at 12 hours which I only do on weekends). So the 8 hour rule doesn't apply for everyone.
It's pretty bad though. Remember Heartbleed when people couldn't revoke their compromised certificates?

Also, if you read the Namecheap promotion page, they explain that they are donating $0.5 to Fight for the Future for every purchased certificate.
I think I understand his point, I find myself meeting up with and spending time with friends and acquaintances who at the end of the day...don't always add much value to my life. And that time spent, the time I feel obligated to give them could have been spent doing more productive things.

That isn't to say I don't have close friends who do add value to my life, those are the people who are worth spending time on. I don't think its about being a hermit, its about being more selective.
