This is a point most people seem to forget about. It's reasonable for a person on an average income to fly. It used to be essentially reserved for the elites and business travelers because of the cost.

In some ways we as the customers are making our own problem. People put an unorthodoxly large weighting on paying as little as possible to fly, so airlines have the incentive to cut prices any way possible. People will search 5 different websites for hours just to save $20.

Hyvee, a grocery store in the Midwest, partnered up with Casey's (a convenience store chain) to give Fuel Saver credits on gasoline for buying specific products in the store. E.g. Save 1 cent per gallon for buying your canned corn. It's quite popular because people hate paying for gasoline despite the convenience it provides. I simply make my purchases at Aldi and other much cheaper alternatives and come out way ahead.

>The problem is that your car-driving case presumes the driver already wants to go to MV and is bringing his friends and they don’t mind coordinating to make that happen.

This doesn't really make sense. My original point is that for me personally going alone, it is cheaper to drive than to use public transit. If I bring friends it is _much_ cheaper.

At this moment I could take a CalTrain to SF for $33/person or a 4 person UberX to SF for $47.85.

So yup, if I'm traveling alone it's cheaper taking the train than having a driver. Easily stops being true if there's more than one person.

Once there are autonomous cars, paying the driver will go away too and I'd expect that to be cheaper than CalTrain.
A problem for computational science is people care about their publications more than people being capable of reproducing their work. The funny thing is an open source code is a sure way to attain a legacy.
Remember that Boeing's original plan was to use the 747 as a freighter. Passengers would fly on supersonic jets like their prototype 2707 SST.

This is why the 747's cockpit is on top, it provided a continuous open tube for cargo underneath.

http://www.nycaviation.com/newspage/wp-content/uploads/2015/...
I once got to go up to the cockpit as a child, and remember climbing up that spiral staircase, awing at business (or first?) class, and entering the mindboggling cockpit of switches.

Something about that second floor, with a spiral staircase, is magical. Recently, I found out that 777's manage to fit a crew rest area on top of the overhead luggage compartments. I haven't been fortunate enough to check out one of those.

The A380 isn't that popular either. The A380 only makes sense for really popular routes with a guaranteed high passenger count, whereas the 787 is more flexible because it has a similar range and takes less passengers but is almost as efficient per passenger-mile.

And in 2016 there were fears Airbus might even cancel the A380 entirely: https://qz.com/782361/airbus-a380-airlines-are-abandoning-th...
I don't think that's the case, seems a little too extreme to think that. I believe the central point of someone not directly enrolled with programming as an actual job (or as a hobby taken seriously) picking Fortran over C/C++ has to do with the features it has out-of-the-box, or at least that are more apparent from the surface of language knowledge. Even if it takes one afternoon to implement a certain feature, would scientists WANT or NEED to do that?

Don't get me wrong, this is probably an opinion I would defend if it were exclusively related to programmers being "too lazy to learn a new language", but this is a different learning purpose.

I've noticed in my traveling that London and Beijing deal with some terrible traffic despite having transit systems far more developed and comprehensive in coverage than the vast majority of the US's. Which is still being fought e.g. with congestion pricing.

So despite all the comparative advantages of transit in those places, and the higher costs of car ownership, for whatever reason people really want private automobiles. So is it really a US-specific problem or just most obvious in the US, where cities that grew up when the majority of people had cars see no real need for super nice mass transit systems?

I have been developing in Fortran for years. I just mentioned that as an aside.

About C compatiblity: Many C libraries use pointers in their interfaces. Interoperability is indeed defined by the Fortran 2003 standard, which I have used several times to wrap existing C libraries. However, much of the existing code is F90 only (some even F77...), and a vast majority of Fortran developers in the field are not familiar with even modules and other F90 features, let alone iso_c_binding in 2003.

Also, newer libraries tend to be C++ as well, which is more difficult (or at least more awkward) to wrap.

Otherwise, since these notes in the context of a project, I can treat it the same way I treat code. So a mix of multi-file search, and directories that correspond to the knowledge in them (e.g. "finances/investing.txt" or "journal/happiness_project.txt", the latter containing any work I do on http://diurnal.st/2013/05/27/training-your-brain-to-be-and-s...

PostgreSQL has the same feature actually, which I learned as part of a MySQL -> PostgreSQL migration that's underway.

We need this to load the data in without worrying about table order, or even individual row order for foreign keys that reference their own table.

And we'll all try and forget this feature exists when we're done!

> If you use PostgreSQL in the cloud or from a services company, make sure you ask them what they have contributed to PostgreSQL and what their capability is to fix bugs and with what SLA. The answer to that question is what keeps open source well funded for these latest developments and future ones too.

Reasonable sounding theory. How true is it, how significant?

Does that story describe how 2ndquadrant gets business -- other vendors have customers asking for an SLA on PostgreSQL fixes, which would require PostgreSQL experts to meet?

C++'s generic-programming feature still has shortcomings - I think functional-programming has more relevance to scientific computing, but C++'s functional features are "okay" but still not as capable or proven as, say, Haskell's or OCaml's - for example for tail-recursion you still depend on the compiler supporting that optimization, you can't force it or necessarily assume it will happen, with fun consequences for your stack if it doesn't.
Based on aerial views of the burned out subdivisions the problem is zoning. The structures have almost no separation from each other; only 5-10' on average as seen in video from Santa Rosa[1]. In subdivisions where the fire spared some homes the line between the burned out properties and the survivors is often a street; a modest residential street provided enough separation to stop the fire.

So CA and its various governments have been either allowing or requiring developers to plat large homes on tiny lots with next to no separation. Fed by wind the fire leapt from one home to the next burning out whole subdivisions. While the efforts you cite to control brush are admirable they can't prevent this; the houses are too tightly packed and will burn en-mass with no help from brush at all given enough wind.

Bottom line; this is indeed a regulatory problem. Obviously that rankles those that habitually give CA every benefit of the doubt in all things but physics doesn't care.

I'm curious about the strategic thinking behind a post like this. I'd think that the serious money that can be gained by taking marketshare from another database for a company like 2ndquadrant would be in businesses using (or contemplating) Oracle Database, not Oracle (or some version of) MySQL.

A couple flaws in the article. If you don't buy a house but buy stocks, you will pay rent. According to the numbers in the article, this nearly cuts the stock return in half. Also, the article states you will lose money on the depreciation of the building, but does not take into account the appreciation of the land. The land appreciation is highly leveraged, as well, since most people typically place only 20% down on the property, but you gain the appreciation on the gross price of the estate.

But I would say that, here is Seattle, and probably all along the West coast, you do have foreign investment, mainly from China, driving up the cost of real estate.
Frivolous Introduction to Reverse Engineering
I remember ages ago (a decade? or so?) I started working at a company using Postgres for a project, and one of the things my boss asked me to do was to set up replication for the database. We had it on all of our MySQL databases, and everyone knew (myself included) that Postgres was a more serious, enterprise-y, "real" database.

Well, I googled around and couldn't find anything conclusive, so I hopped into the / channel for postgres and asked about it. "Is there any straightforward replication solutions for Postgres?"

It was like the early days of open source all over again. The first thing they did was challenge my needs. "Why do you need replication in the first place?" "Replication isn't a panacea you know." "Postgres doesn't have the issues that MySQL does that makes replication necessary." "Replication doesn't work well in the first place."

A ton of people jumped into what had been a quiet channel to make sure I knew that replication, which postgres didn't have, was something I didn't need in the first place, most of which happened before they even knew why I was asking.

After sorting through all that, a few people suggested "solutions". "Just have a cronjob rsync your data directory over to another machine every minute, and if your first server dies then you can just start postgres on the second one." Other solutions were much more convoluted. Patch postgres, add this software, manage it all yourself. And through it all, they kept telling me that I didn't need replication anyway, "but if you INSIST…".

In comparison, the MySQL channel on freenode was staffed with MySQL employees and volunteers who were always happy to help you solve your problem while teaching you what you were missing and giving you resources you needed. They'd answer questions, help your configuration, and even fix your SQL queries for you, all without being condescending about it or making you feel like an idiot.

And that's why I gave up on Postgres: the community. Postgres's was ridiculously hostile and self-important, verging on insecure and defensive. MySQL's was helpful, friendly, and full of resources. To this day I still hear great things about postgres, and I know it does a lot of things better than MySQL, but whenever someone writes a self-superior blog post about it I always think back to how much easier my life was by using a database where I could ask questions of the community and get useful answers.
In the article, I explicitly mention cities like San Antonio, Houston etc. and link to my source: https://www.numbeo.com/property-investment/rankings_current....
TODOs are crufty ambiguous notes that often poorly describe the current system and potential future work... and they're so easy to add that the average "todo" is very low-value, dragging down the perceived ROI of fixing any tech debt.

I keep the two separate: good notes describing the state of the world, and a calendar to schedule future actions.

When it comes to software, that means all code must have good documentation and known flaws are scheduled to be fixed. If it's not worth scheduling, it's not worth changing.

My personal life follows the same pattern, although much less formal... there just isn't enough time for every possibility, so I always work backwards from my calendar.
language built-ins are not fully replaceable with extensions and libraries. Most notably: (1) Compilers have more ways to optimize if given higher level abstractions, (2) built-ins are easier to use for the user because of specific syntax (e.g. highlighting), (3) built-ins have support in debuggers (e.g. you can easily print an array slice in a Fortran debugger).

just a case in point: what do you think is easier to use, standards conformant and is more typesafe:

a) a typedef that gives you "__restrict const * const double"

b) declaring inputs as "real(8), intent(in)"
Roe v Wade, law of the land. One of the reasons why GOP hate it is it makes privacy a right rather than a product.

The "correct" way is, if a black man knocks up a guy's white daugher, he puts her on a plane to a state where abortion is legal. But in his own state, he fights for it to be illegal, so all the poor people have to have babies, and stay poor. Because classism is good. It makes sure some products can only be afforded by some people. Better people. And better people have more money, and buy more and better things.

Free market means being free to pay as little as absolutely possible for labor. And for that you need a lot of poor people. Everyone becoming wealthy is bad for better people. What's the point of being better if you can't be wealthier than most other people?

And if you think a white wealthy GOP dad won't overnight their daughter to a state to get an abortion, especially when it's from a brown dad, then you're ignorant to the point of cultural blindness.

28.6¢ SFO to LAX

A train is something like 10 times more fuel efficient per passenger. It's a much less complicated machine, and carries something like 10 times as many passengers per vehicle.

It's not reasonable that a train is more expensive. It doesn't have to accelerate to 550 mph 6 miles up. Piloting it doesn't require years and years of training. Compare SFO to your local caltrain station and tell me which one has a bigger impact on ticket price.

> Because the SEC directly asked him to, as an expert on Bitcoin.

What makes him an expert on bitcoin in particular? What bitcoin related works has he published? What contributions has he made? What role does he play in the "expert" community? At what conferences has he spoken? What makes him qualified to comment on bitcoin economics (or economics in general)?

Anyway, I think this is going nowhere. I have seen this exact discussion many times and the end result has never been satisfying for either party. Let's just say the experiment is ongoing and time will tell what the conclusion will be.

As for his agenda, I think he is trying to stagnate progress by pouring gasoline on the fire that is the schism in the community. I don't know what his exact motivation is, but my suspicion from reading the SEC document and his comment history is that he thinks that there is something morally wrong with bitcoin. I admit he has some valid technical points, but it is suspicious that he is so negative about it. You would expect that someone who spends so much time thinking about bitcoin could come up with some ideas on how to make it better, but so far he has not produced anything. There are many bitcoin skeptics out there and I don't mind that, it's part of the experiment. But Stolfi is a special case, he is extremely determined.

Thanks for the discussion, I'm out.
Any language that actually matters in the market reaches a point where it has multiple implementations.
We used Nix to vastly simplify the build process of Simula: https://github.com/SimulaVR/Simula

Simula is a bleeding edge VR Desktop project for Linux; virtually all of its dependencies are highly novel and require building from source for almost any distro. Nix allowed us to reduce the effort to building our project from 1hr of sifting through build documentation to a single build command.

Nix's only issue is that it so far can't handle OpenGL dependencies very well. I'm not sure if this is something in principle it cannot handle, or if it just hasn't been done yet. I'm praying it's the latter.

Right, so the effectiveness of any particular methodology when applied by a team of very good developers isn't particularly useful information. What would be more useful is knowing whether the same methodology brings significantly better results when adopted by a team of average developers when compared to whatever they were doing before.
