Ok i will say it since no one else is saying it. Why do C programmers keep writing one letter variables?

We have hard drives with terabytes of storage, and making descriptive variable names do not increase the file size of the binary by the way.

> Wear on roads is to the fourth power of pressure.

The rule of thumb in civil engineering is actually fourth power of axle load, per axle.

> So the pressure might be 3x and thus the wear 3 x 3 x 3 x 3 = 81 times as much.

Considering the rule of thumb is by axle load (not pressure density) you're off by about two orders of magnitude when comparing a large sedan to an 18-wheeler:

* A Model S is 2T over 2 axles, or 2 * 1T/axle

* A fully loaded 18-wheeler can go up to 36T (legal limit) over 5 axles, or 5 * 7.2T/axle[0]

That means the road wear per mile of an 18-wheeler is up to 2.5 (number of axles) * 7.2 (axle load) ^ 4 (4th power), or 6700 times the road wear of a Model S.

Now that's a worst case scenario (unloaded model s versus fully loaded 18-wheeler), but you get the point.

[0] on average, the front axle is usually ~5.5T with the rear axles being in the 7.5~8T range which increases the road wear difference quite a bit, to about 7500
> I couldn't disagree more! Wear on roads is to the fourth power of pressure.

No, it's probably to the fourth power of force, not pressure. These are distinct and separate concepts in physics.

> We could assume the tyres were solid rubber for the purposes of this conversation and the wear on the road would be the same due to the gross vehicle mass devided by the number of tyres.

Ok, but in that case we must be talking about force, not pressure. Because the pressure is force divided by contact area...

> As another commenter pointed out, I've ridden my bike with 150psi tyre inflation pressure but the weight per wheel is my weight + bike weight devided by contact area of each tyre. Sure, higher pressure tyres typically have less contact area, but the gross weight of the bike is tiny compared to a truck the road wear from cycling is pretty much zero.

Now you're mixing pressure and force in a way that doesn't make any sense to me...

So dmurray is saying that "correct relationship is linear in the fourth power of the weight per axle" which IMHO is correct (but to fit with my argument above I would use the words "force exerted by tire on road" rather than "weight per axle", it's the same).

You (TheSpiceIsLife) are talking about something else... I don't know what... I can't say if you're right or wrong, but I feel quite certain that what you say is beside the point.

My (only) point was that the force that a wheel can exert on the road (what Newton called "action") is

A = [current "overpressure" inside tire] * [contact surface area]

and the force that the road exerts on the tire (what Newton called "reaction") is

R = [pressure on road] * [contact surface area]

Since [contact surface area] is one and the same in both expressions and Newton says R = A it must follow that [pressure on road] = [current "overpressure" in tire].

"your likelihood of being a victim of a terrorist attack is 0.019%. It's just not a real risk"

If you do that for 50 years, your risk is now almost 1%!

I am sorry, but the risk of dying from cancer, heart problems or car accident in the working life period of ages 20-65 lifespan is comparable to that 0,95% "composite subway terrorism" risk.

So if the security problems in Belgium continue, you should totally worry about it.
> I can't say if you're right or wrong

They're right. Civil engineering estimates of road wear for wheeled vehicles[0] is the fourth power of axle load (the weight borne by the axle) per axle, tire pressure does not enter the equation.

[0] following extensive testing in the 60s, repeated a few decades later, the exact exponent is variable but 4 has proven pretty good for a rule of thumb.
> I compare this to human languages. It would be tempting to create a language with minimum ambiguity and clear cut concepts, but it wouldn't be practical.

Lojban[1] is usable in practice (though that may be because it still allows you to be ambiguous when desired).

True. I was talking about [current "overpressure" inside tire] (see my other answer) and not "inflation pressure", so I have taken that effect into account. :P

I can paste various commands for other terminals/environments in a tweet, the same can't always be said for ps. It's just a lot of typing.

Open-source can be used commercially. Forbidding all commercial usage is incompatible with most definitions of "open-source" and thus all important open-source licenses. Code that can't be used in a commercial product is useless for most open-source projects as well.

Generally it is a common pattern to dual-license code as both a) GPL or AGPL and b) a sold commercial license and hope that commercial users prefer to pay instead of dealing with/thinking about the consequences of using the open-source variant.

> Pressure on two sides of a surface don't have to be equal.

Absolutely, and Newton surely didn't say so. :P

(A more close to home example is that the pressure inside a tire surely doesn't have to be the same as the pressure outside the tire. In fact, if it is then we call that a "flat tire". :P)

But the force that the tire exerts on the road (=the "action" as Newton called it) has to be equal to the force that the road exerts on the tire (=the "reaction" as Newton called it). Since the contact surface between tire and road is the same that means that the "overpressure" in the tire (=the pressure the tire exerts on the road) has to be the same as the pressure that the road exerts on the tire.

Most of your heart disease risk is after the age of 65 (if you live in a developed country).

However, most of your terrorism risk and car accident risk is before the age of 65. This is where they dominate.

Do you think that car accident risk is real?
How much fatalities from car accidents were there in Belgium this year?

"Lifetime risk" is stupid metric, borderline fradulent. I don't care about dying at the age of 85, would welcome it after all. I'll care a great deal if my relative dies at the age of 30 or 40.

I was composing a much longer answer before I realised that this is actually a really interesting question. While I try and think through that, this is my immediate reaction. It comes down to one thing: the ABI.

Only C (and therefore to some extent C++) is the first class citizen in all the major OS families we care about, because the C ABI is the standard for compiled objects (whether executable or library).
I think you'd have to follow through in case it didn't turn out that the world was destroyed in the first strike[1] and other nuclear capable actors remained.

[1] there's so much non-information about what would actually happen that the uncertainty is the strongest signal in the channel.

The point of MAD is the "logic" ( that actually inspired Heller to write "Catch-22" ) which is:

Nuclear weapons are no good if you use them. They're only any good if you don't use them.

Played properly, not only is there no nuclear war, there is no conventional large scale war. This happened. We still ran one of the warm spots in the Cold War at the German/Russian border. And nothing actually ever happened.

We could only have stupid and in cases, possibly ruinous proxy wars in Vietnam and Afghanistan (1980 version). That's (globally) better than WWII, conventional or nuclear. Those were not psychologically sustainable. So they ended.

I attribute this to MAD. Any technology which allows us to use one simple koan of bullsh8t to keep from killing each other is a very useful technology.
This is my personal classification.

If I had to trace my thoughts, I would point to Lord Chesterfield, Neil Strauss, and Dale Carnegie, in that order.

Also lots of efforts to change people's (read: friends) behavioral patterns. I think, especially for psychology, most valuable insights come from experience, not books. Read the books, and apply the principles.

Feature Teams in large org
Hello,

I'm looking for more information about Feature Teams ( as explained in this video https://labs.spotify.com/2014/03/27/spotify-engineering-culture-part-1/).
Do you have articles on how big web companies work? Do you know who use Feature teams? How the product teams are organized in your company?

Some context: I'm a PO working in a 300+ people web company that wants to move from platform teams (web, web app, IOS, Android) to feature teams.

Thanks!
"35 people died in the Brussels Metro attack […] It's just not a real risk

28 people died in traffic in Brussels in 2015 (https://bestat.economie.fgov.be/bestat/crosstable.xhtml?data...), and Belgian traffic is dangerous, compared to Western Europe. So, if the 35 is not an outlier, I would call it a real risk.

Yes, it isn't large, but I would guess most unnatural deaths are from causes that each have 'negligible' probability.
By far the greatest part of the time I spent with my two toddlers (5 and 3) is spent repeating the same things, again and again, and trying to find shorcuts for learning (which shorcuts might just not exist, afaik).

Then one day they start to get it (like "fire burns"), but it's still not there for sure until they experiment it deeply multiple times.

The dev in me can't help but see this two little humans as big mighty neural networks who spend their full uptime constantly ingesting tremendous amount of data and being restlessly tuned back by adults and experience :)

Sitting for a pee was one of most unexpected and difficult cultural barriers I had to deal with when I lived in Germany.

My German flatmates were very serious about it, and most houses I visited, most of them multi-nationality, had signs imploring visitors to always sit. Took me a while, and quite a bit of 'public shaming' to remember to sit.

The weirdest part was that whenever I'd have non-German male visitors, we'd usually end up in an argument about the practice because it was perceived to be emasculating! And more than once my guests, otherwise perfectly polite, would just pee standing up anyways.

Or you could just launch the nukes anyway because if there is a thermonuclear war it doesn't matter what asshole started it for which reason unless there's someone alive to hold you accountable when the dust has settled.

I'd have to agree, though I spend most of my time in the node space, today via VS Code (though I don't use the debugger at all). VS Proper with C# has felt better to work with than any Java tool/project I've ever used, though haven't done much with that ever. I jumped on the C# bandwagon in late 2001, early 2002 when it was still in development. Started moving over towards node around 5-6 years ago, and am currently looking for a reason to work with rust or go.

Most of my issues with C# have always, like Java, been about "Enterprise" frameworks, patters and practices implemented where they aren't needed, and complexity for complexity's sake. VS + C# is pretty damned nice, if you can work on a green project and not bring in everything under the sun.
I've built several cross-platforms apps, but never used Appcelerator, the fact that it used C# (Does it still ?)was the main reason behind the fact that I didn't try.

I've used Cordova/Phonegap (where you build webViews, not native apps), which is an OK solution. It's pretty good for rapid prototyping, but the user experience isn't as good as a native app.

>What are the alternatives?

For code reuse & native apps, React native would be a good and modern alternative too.

React native : https://facebook.github.io/react-native/
List of examples apps : https://github.com/maxenceC/open-source-react-native-apps

It's doesn't feel mature yet, but it's a way better solution than webviews.

I've tried some IDE specific for React native, and Deco (https://www.decosoftware.com/) was great !

Probably not the sexy answer you are looking for (i.e. "using my abilities"), but if you have enough free capital (for the mortgage deposit) buying a house and renting it out is a pretty good option.

Depending on where you are you can get 5% - 15% ROI/year, and if you pay someone else to manage it, it'll be very little work.

Compared to creating something from scratch and selling it, this is much more likely to pay off, and most likely requires less work up front.
> I think the naive story about MAD comes from applying game theory but assuming your strategy is static throughout the whole "game".

Care to elaborate?
Personally, I don't think fear of dangerous traffic is a very useful metric for deciding where to live either.

Also, if ISIS does successfully conduct an annual terrorist attack on the Brussels Metro then it might be something worth being more afraid of. At this point, treating it as a major factor in deciding where to live is just fear-mongering—especially when I personally think a place having previously suffered a terrorist attack lowers the future risk.

Just one comment about point 4. I think 0 is only likely if you expect to create it and that customers will come on their own. If you create an SaaS that solves a real problem then you are definitely going to earn money it just won't be passive. Operations, support and marketing might become your new full time job but like acangiano said, depending on what your SaaS is targetting there's no limit on how much you can earn.
A key advantage, I think, of the first approach (Sandstorm's, in theory) is in the capability of apps to run 24/7 and do useful stuff in the background, non-interactively, when the user is offline. Like receive network messages, pull rss feeds, crawl the web on your behalf, or make your idle server's computing power available to your friends.

Toilets seem to come in a ridiculous amount of shapes, at least where I'm from.

actually 5 is a good bet as well for a full time developer. e.g. make a WordPress plugin, give a demo but functional version out for free on WordPress.org, then sell the full featured version on a marketplace like Envato. If your plugin is genuinely useful to someone they will buy it. it won't be enough money to quit your job but it will be something on the side.
