cpwright··on High-Speed Trading Firm Deleted Some Code by Accident
It enforces price priority, not price-time priority. Exchanges can use pro-rata, etc. at the same price level; and if multiple exchanges offer the same price level, a BD is free to choose any of those to route to.
cpwright··on Meet Model X
The $30K vs. $100K isn't the real comparison though. The pilot starts at $30K, but goes to $48K. The MDX is only 7 seats, but is also basically a Pilot for $58K.

A Model X should come in around $80K, assuming it is just a bit more than a comparable Model S, which starts at $70K.

I think one of the things the Model S has done is get someone who might spend $50K on a car to spend quite a bit more than otherwise, because of its coolness factor. I think the Model X will do the same thing, and get people who would otherwise drive something less expensive (in the $50-60K range) to reach upwards to $80K or so because of the cool/wow factor.

I've got a Pilot now; and like it. I need to see the X in person. Right now the falcon wing doors are not a selling point for me and lack of rear-seat entertainment system make it less compelling than it otherwise might be for the money.

cpwright··on Meet Model X
The pilot is pretty popular as an 8 seater. It's rear seats fold flat giving you a reasonable cargo area when you don't have the 3 people in the third row. The seats themselves aren't very cramped, but getting in/out is not great.

They'll be allowed back on the road; but you can bet that there will be backlash about them losing performance because of it.
cpwright··on Volkswagen Is Ordered to Recall Nearly 500k Vehicles Over Emissions Software
In NY the first year is safety only; but year 2 and on are emissions + safety (depending on the county you register your car in, some never need emissions). The safety inspection only costs $10; IIRC the emissions + safety is $37.
cpwright··on Totally Honest Software Engineering Negotiations
Its better to make the extra cash in the meantime and then have to take a pay cut than to not have the money at all.

I will say that by the third time he's demanding more money with another offer; they should have said, "good luck." Matching once makes sense, matching twice, maybe. But the third time, you should just let him go.

cpwright··on New York Mayor De Blasio to Require Computer Science in Schools
The original title "De Blasio to Announce 10-Year Deadline to Offer Computer Science to All Students" is a better headline. Of note in the article, "Computer science will not become a graduation requirement, and middle and high schools may choose to offer it only as an elective." This is quite different than the HN modified title.

They have to pay you not to work if they elect to enforce it; the contract actually says that. They don't actually enumerate who is a competitor, but in practice they aren't interested in enforcing against Google, Facebook etc.

cpwright··on Mortgages Are About Math
As a counterpoint, I'm not sure why anyone would use a broker when it is clear they also need to get paid; and you can call a dozen banks to get their interest rates for whatever kind of loan you're trying to get yourself. When you're talking about hundreds of thousands of dollars (or maybe even over a million), doing a bit of work yourself seems like a good idea.

They also run around and move garbage cans in the street where they can get hit by cars.

They also ride on the side of a truck, just holding onto a handrail and a step. If they lose their balance or grip that could be end badly too.

cpwright··on Pink Slips at Disney. But First, Training Foreign Replacements
I wish I could think of a good way to produce incentives that would negatively affect Disney; but Disney isn't the one doing this hiring its Infosys. So although Disney is reaping the benefits of Infosys's cheap labor; it is Infosys who is using the H1-Bs. The added level of indirection makes it more difficult in my mind to come up with a sane way to disincentivize this behavior.
cpwright··on The Story of Microsoft's Minecraft Buyout
> I don't know how it is in most countries, but in the United States, an employee gets unemployment when they get laid off. A founder gets nothing when the company goes under.

The $350 I got a week when I was unemployed three years ago doesn't affect much of anything compared to a developer's salary. I am fortunate in that I received 2 weeks severance and was able to get a new job within about a month; but not everyone is going to find a job within a time frame that having a drastically reduced income is trivial.

cpwright··on Test drive of a petrol car
You don't pay at Tesla stations, because you've prepaid for the supercharging option. They may have recently eliminated it as a separate ~$2,000 option with the introduction of the 70D, but that just means it is rolled into the price of the car.
cpwright··on “DBus is seriously screwed up”
The thing is Linus does know what he is talking about; and can separate the performance concerns, from functionality, etc. I think the real point of the message is to change dbus not the kernel to address the performance issues.

But if someone without the proper technical understanding looks at the just the pull quote, they might think it is a lost cause or not worth using.

cpwright··on Death for stealing candles
Candles were certainly more labor intensive and valuable when he stole them than today. Consider the example of the $3500 shirt: http://www.sleuthsayers.org/2013/06/the-3500-shirt-history-l...

As in one of the other comments, you'll see that it is worth about $6000 if you look at GDP per capita; which would be more than a month of someone's effort at the current US median income.

cpwright··on How to live large in a tiny house
It is true that I didn't include tools; trim and finish also add to it depending on what you're doing. When you're doing demo, you may also need to fix or match existing finish work (e.g., you might have interrupted hardwood floors or carpet where there was the old bottom plate).

But building a wall actually requires fairly few tools. You can get buy with a hammer, handsaw, square, and level to do the framing. For the drywall you need a utility knife (for cutting the drywall), some drywall taping knives, a paintbrush and a roller cover.

You can certainly add a drill (to screw it together) or rent a nail gun/compressor to make things go faster. A circular saw is also one of those things that it makes sense for a homeowner to have.

But even if you aren't doing it yourself, you can pay someone who has those tools, and it shouldn't take them that long. Stick construction with drywall is easily modifiable (as compared to e.g. concrete).

Also, I think that now with the advent of Youtube and online forums; things are a lot easier for someone who wants to do it themselves. You can see videos of people doing it, you can ask questions related to your specific situation (which even if you read a book may not be covered, because everything presents just a little bit differently).

It's very empowering to be able to improve your living environment.

cpwright··on How to live large in a tiny house
Knocking down or throwing up the structure for a partition wall isn't that expensive. If you want to build something like 16 linear feet of wall, you need 4 panels of drywall ($40), about 16 2x4s ($43), some tape ($2), joint compound ($15), a gallon of primer ($20), and another of paint ($30-60).

All in all, you can do that for about $200, if you're willing to do it yourself. This neglects doing the electrical (you don't need plumbing for a partition, but you do need outlets every 12 ft so that there is no space on the wall with more than 6' without one).

Until you get into moving structural walls, or doing kitchens and bathrooms; you can change the interior of the house fairly cheaply. Depending on where you live, you may not need any permits either if it isn't a structural change.

cpwright··on Higher wages and employee turnover
It may not be more cash compensation; but having a greater degree of certainty definitely has value as far as trying to plan your life.
cpwright··on We Can’t Let John Deere Destroy the Idea of Ownership
> DRM can only protect information not the operation of a physical device.

So I think it would actually be reasonable for the DRM to protect a physical device; but the contract should be structured as such.

If I have title to my car and can dispose of it as I see fit; I shouldn't have to abide by DRM. If it is rented and doesn't actually belong to me, then I could see technological mechanisms such as limiting mileage or range as a valid way to enforce part of the contract.

What the line of appropriate vs. not appropriate is of course not necessarily black and white; but I do think John Deere is in the wrong here and the farmer is in the right.

cpwright··on Code Inflation [pdf]
If you're relying on an empty binary, or exit 0; instead of an actual binary you have to execute a shell process to evaluate it. The binary doesn't need to load a shell, it can just do a bit of setup, then make a single exit 0 system call.
cpwright··on The Roomba for Lawns Is Really Pissing Off Astronomers
There is a lot of work involved in vegetables and fruits, and to some degree shrubs. Most anything that you like, deer will also like. You also can't as easily run around and play various games in something that has shrubs all over it. All of the examples you are showing are, in my opinion, trying to create an outdoor sitting room; which is not what many families want (in my case, I have a deck for that).

I don't water my grass, and it isn't as pretty as some people's yards; but it is perfectly fine for playing in; and looks decent enough.

The whole "sprinkler systems are bad" argument doesn't hold much water in suburban NY.

cpwright··on The Roomba for Lawns Is Really Pissing Off Astronomers
Yes, but they are arguing that using the invisible fence wire is too costly/difficult for a lawnmower. I can see that argument. A basic consumer lawnmower is probably $200-600 right now. An installed pet fence is quite a bit more.

Also, installing a pet fence, e.g. across driveways and paths can involve asphalt/concrete cutting, and a bunch of trenching. That is the kind of thing that even if you're willing to pay may have you say that it is just not worth it, compared to sticking some stakes in the ground.

The market is interesting here; you have to have someone who will spend enough on a fancy lawnmower, but not so much that they would outsource it to a landscaper.

cpwright··on I was interviewed by Fog Creek
I'm not saying a shell isn't useful. I don't use an IDE for any of my git workflow (I actually find git to be poor on Windows, which is a good reason to choose Linux); but for navigating the code.

Shell utilities that deal with plain text often get the nuance wrong, because they don't have the full syntax tree to deal with. Mostly you're using regular expressions; which often get you close but not quite right. For navigation, people often would use cscope/ctags something else anyway; and text searching often isn't as good as a semantically aware find.

I don't use an IDE beyond vim for my C++ work; but am considering clion. So far I'm not entirely convinced, it doesn't handle some of the more complex C++ constructs correctly.

cpwright··on I was interviewed by Fog Creek
Renaming a java variable or permuting arguments in IntelliJ is far easier than trying to do the same thing with grep/sed. IntelliJ happens to work with both Windows and Linux, but I've found that I'm certainly more effective programming Java in an IDE than without.

cpwright··on The Shut-In Economy
I'm not against paying money to avoid doing things you hate or something you enjoy more. I just often hear something to the effect of, "My salary is more money / hour than I'm paying for the service, so it's a good for me financially." If you're not paid hourly, that's probably not true.

I'm paying an accountant to do my taxes, not because I can't do them; but because I don't want to. I mow my own lawn, because I don't mind doing it. I pay someone to clean my house once a week, not because I think it makes me better off financially, but rather because it is no fun; I would rather do something else (e.g., engage in some kind of home improvement).
