> Uber's only UI is their app. There app will never be optimized for renting trucks.

First of all, you're wrong. Uber also has an API, which is for another kind of user, but it's still an interface that enables selected developers to access all of their functionality.

Second, what makes you think Uber couldn't create a new app that connects to the same backend in under a month? There is no such thing as "permanent advantage" (or some companies would live forever), and there sure as hell is no such thing as an advantage based on UI.
I think the problem is that operating systems aren't that useful until they have applications and a userbase. Some projects (like Mirage[1] and a few others) try to get around this by building on top of Xen, but that creates a lot of friction.

I demonstrated that you could still get a worse result with mutual cooperation than you could with mutual defection, which violates the T > R > P > S condition for the dilemma to be a prisoner's dilemma in the strong sense. I demonstrated that at least two of the four possibilities are unpredictable. Mutual cooperation doesn't necessarily give you a better result than mutual defection. Mutual cooperation could give you a much worse result than cooperating while the other player defects. For example, you could get a college degree like everyone else and end up working at McDonald's with $50k in debt through mutual cooperation. But you could also just work at McDonald's without getting a college degree (and the $50k in debt) while everyone else gets a college degree.

QED, sir.

AWS linux instances range from $0.50 to $5.520 per hour. The most expensive instance (x125) will cost $496,800 per month.
As far as I'm concerned, if they don't have SSDs they aren't in the same class as chromebooks. SSDs are what have made cheap, low-powered laptops feel fast for basic, non-CPU intensive use. The chromebook model is to make up for the limited capacity with online storage, which has only recently become workable for many uses.

The cloud model also lets chromebooks be literally disposable in a way that most computers can't; if it fries you can just grab another, sign in, and it's just as if you were using the old one since all your data is stored remotely anyway.

Too be fair it looks like they're "just" using CompCert to go from C to asm. CompCert has been around for a while and is a verified compiler, which itself is quite an accomplishment.

But yes, it is remarkable how far things have come with regards to formal methods. But it is still quite tedious to do unless you're an academic working in the field.
Don't forget you can't test the ConfigClassesAndProfileResolverWithCustomDefaultsMetaConfig without a set of ConfigClassesAndProfileResolverWithCustomDefaultsMetaConfigTests.

And of course, what about testing the custom overrides of that config?

Well just use the ConfigClassesAndProfileResolverWithCustomDefaultsMetaConfigWithOverridesTests!

Seriously.
> The reason you get the state involved is because good infrastructure like high speed rail is a force multiplier on the effectiveness of everyone around it, even when it isn't turning a profit in and of itself

This is absolutely true. I live a distance from Toronto that can be covered in about 40 minutes of driving, but the traffic jams in the Greater Toronto Area (GTA) are absolutely insane, and as a result it is not uncommon for this 40 minute trip to take 1.5 to 2 hours, with a random but not infrequent chance that it will take 3 hours instead, based on an accident.

A study in 2013 (http://www.canadianbusiness.com/economy/the-end-of-gridlock/) found that gridlock was costing Toronto $11 billion CAD every year. That's just Toronto, and says nothing about surrounding communities. The cost to Ontario as a whole has to be in the tens of billions annually. There's no way that the agencies that build and run public transport in Ontario will earn billions of dollars in annual profits from it, but that's not the point - the point is to create public infrastructure that generates a healthy economy which does return money to the public purse in the long run.
In the opinion of myself, and perhaps others, a "proper" BRT system is few and far between. Even the system their describing in the article is almost exactly what they're creating in real live between Denver and Boulder, but many compromises have been made, and it's not going to work out as originally planned. Funnily, part the funding was through a program called, "Fast Tracks", which - you guessed it, was money allocated for a lightrail system that... wasn't created.
I am not familiar with the ACM’s style guidelines, sorry. I assume most ACM journals are going to have professional typesetters fix up documents to match the journal style, so if you’re just talking about what typeface to use in a draft/preprint, it won’t make it through to the final published paper anyway, so it probably doesn’t matter much. For conference proceedings, I dunno.. maybe make one version for the conference matching the style guidelines, and then a prettier version to host on your own webpage?
The vendor neutral standard for Unix-likes is POSIX, and by some extension Windows to the degree it has compatibility, or that it can be bolted on to via Cygwin or whatnot.

Windows itself is a proprietary platform, but it has no central software repository, so developers distribute their software through all sorts of means. Market share means influence on OEMs is exherted, but is it not also the case that if, e.g. Chrome, becomes a dominant browser that they do not exhibit de facto diktat over many aspects of the web?

Android's central platform is Google Play, but you are under no obligation to use it. You may opt for F-Droid or fetching lone APKs.

It seems to me the only platform where central curation is so ingrained that alternatives become impractical, is iOS.

Not to mention the web, despite being ostensibly vendor neutral, comes with a big problem of its own. Now every single page you interact with, no matter how primitive, is behind the scenes potentially a distributed, unobservable, multi-tier networked application with who knows how many layers of caching proxies, CDNs, ad trackers, analytics, data processing pipelines, etc. etc. with no way of knowing what's changing.
I don't see how you can avoid delays if you still have to follow traffic.
That it may illustrate the article's premise: while people know what's going on with data collection, they believe they are powerless to stop it. Or that we have a society where 5% off is so important that people are willing to give up their privacy to get it.
This may sound rather trivial but honestly the biggest problem I had with the previous book was how targetted it was towards the "traditional" higher-management executive in its language and examples. A lot of them were things that I had a very hard time relating to: preparing for the staff meeting, going over regional sales figures, working on your golf swing. I was sort of hoping he'd write a version "for the rest of us" with more down-to-earth examples.

Given his clientele the previous focus made sense, but since it became sort of viral I was hoping if it were revised it would become a little more all-encompassing. I'd be curious to know if the previous focus was still the case in the new version. (Probably not enough to buy it to find out, though; as I said that was my biggest problem with the previous book and it's not that much of a problem...)
True, I should have said it is not concurrently stopping all the threads. If you actually need the register state of a thread that is currently running on another processor it may be stopped to get it (though if you ask for the state of a thread that is not currently executing you may get its saved register state out of the kernel without having to actually pause its execution, of course being able to tell what is and is not actually running on other CPUs at that granularity is not really feasible).
Thats how much they cost to rent not how much they cost in electricity to run.
That's right, you don't see the same level of vitriol directed at Marissa Mayer or Anne Wojcicki for a reason. The posts I've read have overwhelmingly focused on her litigation actions, her husband's shady hedge fund dealings and her desire to turn reddit into a "safe space" through censorship - all of which are, in my opinion, legitimate points of concern.

Oh, that reminds me: there's also the creeping paranoia that your bus could get there early and leave you behind. I have never had this happen with a train, but I routinely see busses barreling past the stop. And when a route has dozens of stops, you just know the driver isn't checking their clock at every one.

But yeah, smart buses are a great improvement. I love bus stops where they actually tell you how much time is left until the next bus. Can't wait until Apple/Google implement real-time bus tracking in their mapping apps. (I think Google is already doing this in certain areas?)
Woman claims she owns the sun and sues eBay
You prove that you're capable of doing the job by simply doing the job without having the job title. Then when a position opens up (someone leaves or is promoted) you're sucked into the position because you're essentially already doing it and have proved yourself.

If you don't want to play the waiting game, you dust off your resume and find a place with the role that you desire.

Whatever the case, if your goal is to get a promotion, you should really be discussing strategy with your manager. Part of your manager's job is to ensure your success within the organization - they'll have the best insight into what's possible, what you need to do to optimally position yourself, and possible timelines.
I don't think that's implausible, but that misses my main point. If they are officially blaming China, they likely have some solid evidence from inside sources, not just an IP from China. Break-ins happen all the time, everyday, but not everything is attributed to someone because they don't have enough to go on. In a case like this, it could be as simple as a captured email from Chinese intelligence saying "Got those d0x you wanted. lol".

I also wanted to say that several million people would be jobless if everyone decided not to go to college come August. The economy would be shocked by an influx of unemployed professors, etc. That would be a much worse state, relatively, than if some people continued to go to college, as I argued in my first comment.

And there are indeed many valid prisoner's dilemmas in the natural sciences. A clear one I recall is the example of grooming others that Dawkins offered in The Selfish Gene.
Yes for journals, but most CS papers are published at conferences. Depending on the conference, not every paper uses the same typeface - except, most people use Times because it is space-efficient.

Anyway, forget about ACM. What's as space-efficient as Times and also prettier?
Integrity? User experience?
Some of the travel times quoted don't even do justice to reality !

“I was really surprised how well connected Paris is. Both London and the Mediterranean coast are less than four hours away,”

The Mediterranean coast (Marseille) is actually just 3 hours away, and London to Paris a mere 2h15 on the Eurostar train, with stations conveniently located in the heart of each city.

Almost nobody is masochistic enough to fly the London-Paris route, apart from people on connections or some American tourists who didn't do their research and fly by default.

Also "Less than 8 hours" from Stockholm to Copenhagen is actually 5 hours IIRC, on comfy, clean trains with free Wi-Fi and AC power.

> 55% do not know it is legal for an online store to charge different people different prices...

Statements like tell me that the survey was biased. It's making it seem like these companies are doing something that should be illegal when all they are doing is charging what the market will bear.
It amuses me that names in Verilog 1995 (a language with no structures) look pretty much the same: oc48_transp_decode_data.
I remarked to Knuth after a Stanford talk several years ago how great CM was. He told me to thank the woman in front of me who was a calligrapher for him in the '70s. I never caught her name, but I was chatting with her right before that. I think he actually had a few students working on it.
Boses have traffic. People don't like traffic. Trains don't have traffic.
For anyone wondering why Eastern Europe is so badly connected, it's mainly because the Russian Empire used a different gauge to the rest of Europe:

https://en.m.wikipedia.org/wiki/Russian_gauge

In the Baltics there is an ongoing project to upgrade and switch to standard gauge, which will provide a direct link from Berlin to Helsinki (to start with via ferry, but a tunnel is planned). However a lot of trade done there is with Russia via rail, so it's beneficial for them to keep that as seamless as possible - switching passengers is one thing, cargo is another. Lithuania apparently transports 57% of goods by rail.

As long as we distribute "HTML is done" messages in HTML, it is not done. Well played, though.
That's very personal. I really enjoy the rustle of a bus engine. It makes me dozy in a very pleasant (if inconvenient when I have to get down) way. Trains are great for transportation, but I don't enjoy the trip as much.
Meditations is hardly self-help...

I'm not going to deny the fact that it changed the way I look at the world though.
I’m a fan of Slimbach’s typeface Minion, which is quite compact and looks sharp in most any context where Times would be appropriate, but doesn’t call any special attention to itself. A version typically comes with any Adobe Pro apps from the past decade at least, and in some cases is the default typeface I believe. Minion is therefore also quite overused, but not as bad IMO as Times or CM, and it’s much easier to make a good looking document with than Times is.

Heels accentuate the legs. I agree though, there's something very attractive about a woman in slacks, sneakers, and a loose-fitting Guns-N-Roses tshirt.

That'll depend on your location, skills, experience, and perhaps most important of all, your ability to convince someone that you're worth paying $200k. A great friend of mine was the sole(not just figuratively, literally) IT/developer at a pharma company for a good portion of his 20's, making ~$50k with slow incremental raises. Finally after several years of being undervalued, he had enough, and gave his company an ultimatum that he found another job(one with a massive raise). He agreed to consult part time to them to help train the replacement, but no one could get up to speed well enough on the complexities of the system in use there. After several months, the company was in dire need of him to come back, and he agreed on the condition that the company let him consult there for $100/hr.

I'd say he's the exception, in most cases you're probably not pulling that kind of money unless you're at an early stage of a startup. Not too likely, but not impossible either.
Yes they do. When someone is carefully carrying a large item around your house many want the option to tip. Default it to 0.00 and communicate that it's not expected. Like Lyft.

Is Fleetzen registered in Washington and/or with the FCMSA as a freight broker and compliant with all state and federal requirements for brokers?

Are your drivers properly registered and compliant with state and federal requirements for household goods carriers?

If not, what is your rationale for believing Fleetzen and your drivers are exempt from registering and complying with state and federal regulation of carriers and carrier brokers?
Yep, motion sickness is a big deal for me. I can use my laptop and work on Caltrain, which is something I'm pretty much unable to do on any other moving vehicle. Not even on an airplane. :(

Has to be a smooth train though. Can't work on BART either.
Yes, to the best of my knowledge the limitations placed on use of funds are only for the funds being appropriated by the current bill. In fact amendments that do otherwise may be removed under procedural rules, but it also seems that if no one raises a point of order then it is not enforced.

I actually got curious and looked at a bunch of other amendments[0]. Another one that was agreed to was "An amendment to prohibit the use of funds by the Department of Justice in violation of the Fifth and Fourteenth Amendments to the United States Constitution; or to repeal the guidance provided in the memorandum issued by the Attorney General on March 31, 2015."[1] That makes me wonder what was in the referenced memorandum.

This one was withdrawn by unanimous consent; make of that what you will: "An amendment to prohibit use of funds to transfer cell site simulators, or IMSI Catcher, or similar cell phone tower mimicking technology to state and local law enforcement that haven't adopted procedures for the use of such technology that protects the constitutional rights of citizens."[2]

There were also a whole bunch of amendments that had this form: "An amendment to reduce and then increase funding for NOAA Operations, Research, and Facilities by $70 million."[3] That one passed but there were at least seven others failed or withdrawn (both before and after this one) which were identical in all but the cash amount, and a few more for agencies other than NOAA. Does anyone know what the point of these amendments are?

He's not saying "HTML is done" as in "over" or "not to be used". He seems to mean something along the lines of "feature complete" and suggests further efforts focus on parts of the web that are lacking (JavaScript, DOM, CSS).

I'd love to see more of the sort of information for other cities, seems like it could be brought together in some sort of wiki or OSM-based system to allow crowd-sourced data.
Firstly, the K&R2 is outdated. It was published in 1988, a year before ANSI C. It has not been updated since. As a reference, it serves only long-time programmers who steadfastly stick to ISO C 90.

The K&R and K&R2 can be likened to sales brochures for the C language, which promote the language to users of other systems programming languages and provide a mini-reference to get them started.

I started learning C circa 1990 from K&R2. A few years later I started reading the ISO C standard and realized that much of what I knew was wrong. I had a "wow, so that's* how it actually is"* moment on what seemed like every page. It's not that the K&R2 explicitly teaches wrong things---obviously not; rather, it misguides the inexperienced by omission. You're expected to be an expert programmer who reads between the lines, asks the right questions about the limitations of constructs and consults a reference manual or standard to have them answered. The book is also not a tutorial on programming, either.

Thus if you're a n00b, you will not learn programming from K&R2 and you will not learn C properly. A combination of K&R2 together with Andrew Koenig's C Traps and Pitfalls might be better. If you have those two books, plus the Harbison and Steele reference manual and a PDF of a draft standard, you're in very good shape as far as being well-informed. You still don't have a great tutorial though.
I've had to wait in a train for over 30 minutes due to another train passing by. I guess it depends where you're at.
Oh, I'm quite aware. So are the miners, and so are the Bitcoin core developers, who are increasingly starting to think that Bitcoin will never be able to shift completely over to miners' fees as a way of funding the Bitcoin network, and that the existing block reward subsidy (read: money supply inflation) might have to continue instead of being phased out the way Satoshi had envisioned.
