If United (Or Republic Airline) flew an Embraer 170 (same as 3411) just for the crew that needed transport to Louisville, the cost would be about $5k for a round trip. The E170 costs about $2500 an hour to operate.

Stupidly, The cost of the likely lawsuits (even from lesser incidents, that didn't involve beaten passengers, just extremely annoyed passengers) often negates any cost saving for the airline.
This actually makes sense. When the low level stuff is at a terrible level they made Octane to make that better. Once that was fixed, optimizing for it is counter-productive.

This has a big resemblance IMO to most formal study methods including University and natural languages. Once you know the basics you can optimize for learning or for grades, depending on your goals. They are correlated (but not strongly correlated), but the time investment is not negligible so you'll have to choose either of them.
Something that has been serving me well over the years:

export PROMPT_COMMAND='if [ "$(id -u)" -ne 0 ]; then echo "$(date "+%Y-%m-%d.%H:%M:%S") $(pwd) $(history 1)" >> ~/.logs/bash-history-$(date "+%Y-%m-%d").log; fi'

Creates a daily log file of every command entered. Searching for anything is a simple grep command.

Would rust fit the bill though ? It's not as mature, and don't support as many platforms yet, but it is considered now as a serious safer alternative, with as much bare metal capabilities.

You don't have to. Most alternative can call compiled C libraries. Rust can.

I appreciate you making this comment.

Too many places I frequent have had crews, and especially airline pilots, basically pulling the "my word is law, there is no appeal and no review and nobody above me but God and even He only has an advisory role" crap.
> Hmm... I think that the left is split on legalizing prostitution.

I remember arguing the complexity back in junior high - and my opinions on the matter have changed and become even more nuanced since then.

1) I personally believe that sex work should be decriminalised, with the caveat that:

2) Sex work cannot become an expected option for a profession

The reason for my second point is that there is a very short and very steep slippery slope from that to the stage where job centres will turn into de facto brothel funnels. One ugly aspect of being an unemployed job seeker is that turning down job offers, even those where you don't have the matching qualifications, risks cutting off job seeker's allowance.

I do not want to live in a world where such qualifications can be callously reduced to "breathes, has useful orifice(s)".
It's not about being broke. It's about:

"I need this tool to solve this problem right now. I can either go bug someone for the credit card and get off track or pull out my own card, get onto putting out the next fire, and settle the cash later."

And as I noted, it's not a long term thing.. it's to allow experimentation in the moment.
I'm not sure it's crowd following in this case though.

For us (who are supposed to be objective) it shouldn't be a case of who we like or don't like or big evil corporations (which Monsanto well indeed may be, not arguing that point) but rather the objective evidence. And as far as I'm aware glyphosate objectively isn't very harmful to mammals.

It's a substituted amino acid. As opposed to something like paraquat which breaks cell membranes and generally is toxic to pretty much all biological forms.

Wow.
a personal anecdote about SW and lost bags -- they put my and my mother's luggage on the wrong flight once a few years ago, and not only did they give us both $250 in credit, they also had a courier drive the bags to her home (an hour from the airport) the next morning. i was very pleasantly surprised.

Which books have you guys read?
Your position is very extreme. Extreme enough that I don't think it's a productive use of time to debate with you.

Maybe tone it down a little, take a breath, and realize (a) that people are not in fact dying, and (b) if they do, we can deal with it then.

The problem with all of these "People might die!" arguments is that everyone who makes them is always thoroughly convinced that they are right at all costs right now so just fix this!!! that it gets so tiresome.

Neither of us has considered all of the possible effects of either action, so we should both carefully examine the consequences of our respective opinions.
And regulations can make all such waivers nonbinding in whatever cases are deemed important enough, like IoT devices for example.

It's worse than that, really. I've got people on reddit telling me that policy -- which they say I can only read if I FOIA it, maybe -- is that all disputes with passengers are supposed to immediately escalate to police as a first and only resort. Because "9/11", apparently.
None of those links work...
What do you mean by "insurance-pharma exclusivity"?
A more likely scenario of crew being out of position (or exceeding duty/travel time, and insufficient rest) would most likely result in a cancelled flight, and that would be relatively expensive for the airline.

The cost of involuntarily bumping 4 passengers ($800+ x 4) assuming no further incident, rapidly approached any benefit from not cancelling (or delaying) the morning flight. Total revenue for the regional flight would likely be less than $10,000.

> The opinion that a point-free style is "beautiful code" seems pretty esotheric to me.

It feels to me like there's this weird disconnect between people who talk about beautiful code and those who don't. For me, the aesthetic criteria that would lead me to call a piece of code beautiful are things like clarity, ease of understanding and simplicity. Writing code in a certain way might even elucidate the structure of the problem for the reader.

Now, concision is definitely something that matters to me aesthetically, but if it comes at the cost of clarity, it just isn't worth it. I would consider very concise but complex and inscrutable point free code to be ugly.

It definitely is my opinion that much of the time point free code is beautiful by these criteria. It's also often the case that I find point free code ugly. The thing that makes it difficult is that whether code is readable is heavily subjective. It very much depends on the familiarity of the reader with the functions and combinators and constructs that are in use. And of course people differ on the level of fluency in the language and language constructs that should be expected of the reader.
> Using eyes and ears and just being aware of my surroundings.

Hmm, not quite the best sources of information then. Have you talked to anyone on the ground? Have you been an election observer or volunteered in any? Have you read the independent reviews of the EC? Talked in any detail to senior officers in any branch of the executive who may offer perspective?

> Trivial counterpoint. Pickup a state, say West Bengal. Count the number of egregious incidents of violence and intimidation reported by competing political parties and the media, including live videos. What action has the EC taken and what has that changed.

Hardly trivial. This is a law and order situation, and is dealt with appropriately.

> ... and then does what ? You are being completely naïve in the open bedfellows relationship with IAS and politicians. There are exceptions, but rare.

Naïveté is an easy thing to call upon in cases when information isn't easily accessible. Your statement, to me, makes it appear that not only could you have wrong or incomplete information shaped by public media - you're not willing to even consider that this may be the case!

I have both been depressed and spent time with depressed people.

The problem with this conversation is that the idea you unpack from the phrase "higher being" isn't really like the idea they compiled to that phrase. There's a fundamental translation problem in that things which are simple structures in one framework are hard or impossible to express in the other.

You have to understand what the reverse image of that phrase is in their model, not what the reverse image is in your model (ie, the idea they were trying to convey, not what you would have been trying to convey using those words). This is obviously extremely hard, as we only have access to our own model, not theirs.

For places where the models are similar, this is less of an issue, because the two reverse images are then similar. However, when the models substantially diverge, it leads to one of the most common breakdowns in communication we see (and we see it a lot, across topics).

I mean, modern mathematics happened because people had different internal models for what "function" meant, but you seem to think a concept like "higher power" is easy to translate.

For what it's worth, I don't think the two ideas are incompatible -- could you elaborate on why you do?

If you need a high limit but don't have strong credit I'd recommend the Amex gold charge card. I was getting $3-5k limits on other cards but got a 50k limit straight away with this card. It had the 3x rewards on certain categories like online advertising mentioned above, but the balance must be paid in full monthly.
This is really the way to look at it. Someone is owed some multiple of their one-way fare as cash in hand when involuntarily denied boarding. The odds of it being you are as low as 1 in 800.

On the other hand you could have vouchers in hand, guaranteed. And at 'just' $200 you can fly one way across the country and round trip to many places, and the airline can save some money. I wouldn't take $200, that said I've often taken $400+. Further, if they need multiple volunteers airlines in my experience tend to give all volunteers the highest amount required to convince the last guy.
No, it isn't. And OP indicated "work email" and was advising use of vendor@ email.

Sorry about that, I'm updating that FAQ next.

The answer is that SMS is not a secure second factor (it's easy to hijack and eavesdrop on), and in some cases when you give a service a phone number, it becomes possible to take over the account with just control of the phone number.

If some startups failing is the price we have to pay to get proper security around IoT devices then I'm all for it.

Not sure what you mean. You always know which row contains any given address, the problem is that "seeking" in DRAM takes tens of nanoseconds (for contemporary chips), regardless of DRAM's clock speed or DDR/GDDR/LPDDR 1/2/3/4/5/6/7. Seeking in your "index" would take time too.

The only way to get good performance from DRAM is to always write data sequentially in the same order they will be read. Then you get full sequential throughput both for writing and reading and this is many GB/s and keeps increasing with clock speed. But that's a software optimization.

Otherwise caching is beneficial, but the cache has to be SRAM to have low random access latency. SRAM is physically larger and power hungry, half of a modern CPU is cache and it's still only a few MB.

Well, that's not smart. Employees should use company email addresses for company work.

OP stated "work email" and advised use of vendor@ email which is what I was objecting to. Everywhere I've been, using vendor@ emails has been a pain and employee emails a non-issue.

Assume the option of substituting manual labor for Roundup was feasible it's quite probable many more people would die of skin cancer from being in the sun or snakebites or hoe accidents or car wrecks on the way out to the field than currently die from Roundup.

I love the environment and nature but sometimes we cause bigger problems trying to solve smaller problems. And pay extra to do so.
Even if you have more servers, you'll still very easily hit the case of rate limiting someone too early. And that's really bad, because it means your clients, who are aware of the rate limit and structure their code to stay under it, will start getting failures they shouldn't get, and they have no way to handle it besides intentionally staying significantly under the advertised rate limit.

So if you're really set on doing something like this, you need to set the actual rate limit to be significantly higher than the advertised rate limit, such that it's extremely unlikely for a client to be rate limited too fast.
I really hope that Uber's shenanigans get studied in ethics classes in Computer Science and other technology degrees. When I was doing my CS degree, we had a mandatory ethics class (which I hated at the time but in hindsight think is a good thing). Ethical implications were something I hadn't previously thought of much, but in the field I've encountered them many times.

Based on the news that has been coming out from Uber, I think it's time for our industry to re-focus on the ethics of what we do. Being technologically cool, doesn't make something good.

> WeChat doesn't block or QoS other IM products

What I mean, telecoms might block IM service because SMS market were rapidly replaced by IM apps. It was highly disputed around 2012. Wechat generates so much traffic that their poor 2.5G cell network can not handle signal storms.

Not only that, Wechat had VoIP capability, which requires a high level license to operate in China. The whole OTT controversy can be found here https://www.zhihu.com/question/20847225

> WeChat works with various partners including "phone security" apps to make sure that this background process isn't being unnecessarily killed

Exactly what I meant, Tencent was large enough to negotiate, while other smaller IM brands were not so lucky. Wechat's success was standing on a giant's shoulder.

> because certain security vulnerabilities on older versions of Android system browsers

But newer versions of android Wechat still refuse to include system default browser as webview even if it's more up-to-date and safer, no?

And if they'd called it the MacBook Premium I'd be happy.

But if you are a professional photographer, video editor, animator, mechanical/civil/chemical engineer, or yes, a software developer, and want a truly "Pro" grade laptop, Apple doesn't make something suitable for you. Instead I'd have to recommend Dell's Professional line, eg the Precision 5520, which can be customised to have Professional things such as a security cable lock, 32GB RAM, an SSD as well as an extra HDD, and the choice between a high-resolution IGZO touch screen and a 1080p matt screen.

It also comes with more than one type of port for maximum compatibility without needing a bag full of dongles or a bulky dock. And frankly, it looks just as good, if not better, than the MacBook.

How many personal possessions can you think of that cannot operate unattended, but should?

Given that my personal possessions are few to begin with, I have a short list to review.

I honestly can't think of a single one, save my refrigerator, which I do not want buying food for me. To be honest, I don't even like owning a refrigerator. I didn't need one in college, and still don't need one. I don't use DVR, because I don't subscribe to cable TV.

My arms aren't broken. I can get up and turn a light on. Self-driving cars are technically beyond the scope of IoT, even though the "T" in IoT is deliberately vague.

But these are the things in my life, as it is, and not how it could be. The way my life works right now, I spend (at best) 10 hours away from my home, and maybe 8 hours asleep. So possibly 6 hours to reap the benefits of more clutter, automating... whatever.

Even though arranging and aligning the automated systems that hypothetically support the maximization of my free time, consumes time in order to perfect. But wait! Planned obsolescence promises me that if I step onto the product treadmill, it will be harder to exit, ensuring that there will be cycles of realigning and integrating new IoT systems, into my own private ecosystem of personal automation!

We know this, because look at how often we discard our mobile devices, and even our laptops and desktops.

But nevermind that. Maybe I'd value my free time more, if I had more of it. Maybe if I wasn't lashed to a desk all day, working for someone else, living paycheck to paycheck, I'd have more freedom to expound upon all the nothing I can't imagine not doing at the moment, because I'm consistently busy on someone else's terms.

I don't want robots buying shit for me. I don't need robots telling the world which room I just walked into. I'm sick of going to work all day, and sitting in someone else's chair. Fix that, before wasting my paycheck on lightbulbs that change themselves, but never go out anyway, because I'm not even at home 40 or 60 hours a week, and I'm asleep in the dark for another 50 besides.
I have a vive and what I don't understand is why I need to use chromium or nightly firefox to view this content when it is out on official mobile builds. Does anyone know why this hasn't made it into official desktop builds yet?
