This is correct. The mixture is almost always propylene glycol, vegetable glycerin, nicotine, and flavoring. I don't know of any negative effects of propylene glycol and vegetable glycerin, and as long as you don't use a carcinogenic flavoring (they exist) your biggest problem will likely be nicotine.

I don't think nicotine is good for you, but vaporized nicotine seems much less dangerous than smoking a cigarette.

I think having separate bag fees actually increases price transparency — it’s right there in black and white when you purchase tickets. And since the price is separated out from the price of the tickets it’s harder to play a game wherein the real bag fee is hidden. And, airlines can compete on bag fees.

Having to pay bag fees sucks but then again, before separate bag fees we were still paying them, we just didn’t know how much of the ticket price they really were.
Because partially structured data is essentially unstructured data. So, you ultimately need a way to store unstructured data.

Those airlines already exist, and would be eager to operate in USA and provide us with service superior to that provided by domestic carriers. The "market failure" is regulations that prevent foreign carriers from serving domestic routes.
Yeah. Easy to say.

Seriously, doing that is often extremely difficult. For many in tech, and people oriented / facing work, there is a cycle of stress and or anxiety relief that amplifies when quitting.

Ability to create and interact with people in difficult or higher pressure scenarios are all, can be, very significantly impacted.

For many, really quiting takes a significant life event, or a substantial period of time away from the triggers as well as the cigarettes.

Of course people vary. Some can do it cold, others patch, others can use drugs like Chantix.

In my own scenario, Chantix was very bad news. Did not work, and I had those side effects. Big. Was scary and all escalated over a matter of a couple weeks.

I had started in the military, and quitting was a serious struggle. Vapor pens got me off tobacco, and the benefits were more or less immediate! Overall well being shot up fast, and continues on a slow ramp up.

As harm reduction, I have little question in my mind. The two are almost not comparable. Night and day type stuff

I have been diluting the percentages down and it has reached the point where I am going longer times without thinking about it much. All that with marginal inpact on create and people handling / interaction too.

Life has been tough on a number of fronts, basically denying me the time / space needed to deal hard core.

Vaping ranges from a fairly tepid thing to obnoxious big clouds where the room ends up a sticky mist!

Mutual consideration points to some regulation, and so far I see nothing unreasonable.

People judging others harshly on various vices has never been a thing I find productive. (Not implying you are, just making a germane point here) Minimizing harm, making sure people have options, treatment when they get into trouble are all much more productive and sane policy.

In basic terms, vaping is not even in the same class as smoking is. The big cloud people do approach that, and a few of them going to town can make a mess on par with smokers generally, but doing that is an edge case.

The vast majority will do it in the same way people use wine, as an example. Real addiction will creep up on people. Happens, and the very last thing they need is a toxic culture adding difficulty to what will already be difficult enough. Just embracing harm reduction would have a hard to miss, positive impact.
No you're not check your camera equipment because airlines don't cover electronics under the plane if they're lost or damaged.
It's less about the safety net and more about re-entering your career at a similar level. In Germany you'd be hard pressed to explain why you took two years off of your career and now want to come back.

Re Europeans traveling around Asia - Europeans tend to graduate university later than Americans and then embark on one or more internships before diving into their work contracts. It's not uncommon to take a break between those transitional periods to travel for a bit. But it is uncommon to leave your permanent contract to travel Asia for two years.
Doing an undergraduate degree is not being in "physics academia". The author transitioned from graduation to getting a job. But good post regardless.
I feel like not being sure what you would do with your time if you weren't working is one of the surest signs you're really truly burnt out. For the intellectually curious, the world has an endless supply of fascinations to explore. For the civic minded, there's countless causes and people who could use your help. For the pleasure seekers, there's a rainbow of experiences left to live. And what better time then when you're young and healthy.

Consider broader definitions of "accomplishment" and "wealth" than "job" and "paycheck."

I speak from experience on this. A few months into a year-long sabbatical my brain had rewired itself and the burnout healed. I started finding enjoyment in the small quiet moments again. 4 years later, I can say that the sabbatical was the best career move, the best financial decision, and the best personal decision I have ever made. It led me to a new home, a new career, and much new wisdom.
Where is the Javascript running, the backend or the in my browser?
It wasn't clear from the article. What kind of wall did they hit?
It's not transparent. Unless you have the ability to construct your necessities at your destination, you can't fly without your stuff. There should be a standard definition of what a flight should include (one checked, 1 person+1carryon). What would be more transparent is to discount those who aren't flying with a carry on or checked bag.

> we just didn’t know how much of the ticket price they really were.

We did realize how much they were apart of the ticket. The definition of what people brought on the plane was figured into by planning at the airline. You can't just pay for more carry-ons and bags than the airline allows. Right now what we have is an artificial price drop and it's being supplemented by fees. (Airlines are pissed that they can't hide the YQ from the price anymore)
I think the parent meant, you have them on a subnet with no default route, but have a vpn / management system with one interface pointing in to the management network. You can get in via the vpn but they can’t get out.

It’s a pretty common configuration.
Paywalls
It seems most paywalls (NYTimes, etc) are applied after the content is already sent. You visit the link, start reading and a few seconds later the paywall blocks the content. I've noticed that if you hit the "stop load" button in the browser immediately after the content is presented it prevents this. Not sure it this is appropriate or not, but thought I'd throw it out there.
Have you ever not known how much your bag costs? Whenever I book a ticket, it usually says how much a bag costs, and there is a link to the extensive rules of what can go in.
I’m in the same boat. However the thing to realize is that you’ll be better off even if you fail, you’ll have a lot of new skills. You’ll also have time to network.

I quit my job to work on a project (http://ngrid.io). I’m close to being done but in the process I’ve met a lot of people and I have three job offers lined up without interviewing.

The airline industry has a lot of issues, but it's not a monopoly. In fact, the reason we no longer have free bags is that the industry is in a state of price war, due to competition. Airlines want to reduce their ticket costs as much as possible, and this leads to little margin on the tickets, so they save costs by not giving free bags.

This helps stratify the market as well, because those who travel light (mainly business people and people who fly a lot) now pay less than they used to. Those who fly irregularly (i.e., tourists) are more willing to pay the fees.
Things moved a lot more slowly back then. News cycles were in terms of days or weeks.
I’ll give you one example where the protobuf design helped out a lot: GWT Protobuffers. The GWT Compiler has a version of Protobufs that transpiles all of the protos into Overlay types of naked JSON objects.

You get a statically typed Java interface, but underneath it a raw JSON object, and deserializing the proto is basically JSON.parse() + a cast.

e.g. something like this

MyProto foo = MessageDeserializer.deserialize(serializedProto);
console.log(foo.getFieldFoo());

compiles to this JS:

var foo = JSON.parse(serializedProto);
console.log(foo[1]);

You completely missed the point.
We don't have it due to the business culture of America.

They're agressively seeking to increase profit margins.

That meant that expensing has stripped away the ability to book business class tickets. (That is arguable if that's a good idea or not given the complexity of tickets)

The aggressiveness about seeking higher profit margins at all costs has also meant that the money that would be available for those things are considered to be "fat".

In the historic world of high-stakes rubber bridge, you're right - players would cut for partners after each 'rubber' game so your partner in crime might soon be your opponent. I'm sure there were occasional big-money scams like all situations involving gamblers and money generally. Roald Dahl wrote an amusing short story about one possibility.

In the modern world of competitive duplicate bridge, there are occasional collusion-based cheating scandals - the most recent one I'm aware of involved a communication system via position of the pencils with which the pair involved kept track of their score. By far the most famous scandal was a pair of English players back in the sixties communicating the number of hearts in their hand (enough to give a winning edge) with hand signals.

Nowadays good records are kept and cheating tends to come to light eventually. The apparatus used in top tournaments is different from a casual game and meant to prevent collusion, and also, with the diagonal screen, make it harder to tell whether any hesitation came from your partner (reducing deliberate or unintentional inferences).

In big tournaments with lots of players, because hands are duplicated to be played lots of times, it's not uncommon for players to be on a 'wire' i.e. deliberately or by overhearing learn some features of a hand they haven't played yet. It causes a lot of outrage and controversy but it doesn't ultimately matter that much. The most important matches are between two teams and things are arranged to reduce the opportunity for the pairs in a team to communicate with one another.

Since I'm writing a pretty long post here, I'll also mention that computers still don't play bridge especially well, so the problem of players getting computer assistance, such a concern in chess, doesn't feature.

All in all, preventing cheating in bridge is kind of an ongoing but not particularly high-profile activity. There's an obvious solution to make cheating even harder - keep players physically separate and make them do everything from a monitored computer terminal, which could also do things like introduce delays to make everything happen in tempo. But the administrators obviously think that would be pretty unpopular and prefer to keep it a card game.

For comparison, in Greece there are tons of young (and older) people actually working full time for ~ €400/month.

(Before the crisis, in say 2006-2010 those were called the "€700 euro generation" for making around that amount per month, then considered very low).

Here's a similar case in Spain: "“We’re not mileuristas. We are just poor. I wish I could earn €1,000, but my generation is earning between €700 and €800 a month,” he says, adding that he personally takes home around €450 a month for a 20-hour week, and describes himself as underemployed."

The knock on effects of biologically active synthetic products are plainly not yet predictable. Current test and assessment abilities only establish a tenuous "not guilty yet" legislative status.

How long is it taking to acknowledge that even a relatively inactive material - plastics - produced without restraint, can devastate ocean life and lead to who knows what destruction or disease, when some tiny little marvels eventually adapt to eat them ?

We must prioritise employment of natural materials simply and plainly because they are less disruptive to biology and more predictable by the knowledge and observation of their fitness in natural systems and natural history.

Of all our industries mass agriculture should be the most careful and symbiotic with environment and biology. Medicine, quarantined lab research, and exceptional problem cases - this is where novel materials and processes belong. Not sprayed across millions of acres and in our loved ones bellies.
That's like saying "murder is proscribed only if you get caught".
That doesn't really answer irrational's question...
Arguably the prices are already transparent, but I think you're arguing that they should be simple and by extension, that complex pricing structures violate the free market. I would argue that complex pricing structures are advantageous for savvy customers and airlines alike, and that unsavvy customers (like me, at least when it comes to flying) should expect to pay a premium for simpler pricing structures.

An analogy would be purchasing a PC; savvy folks can save hundreds while unsavvy people trying to do the same are very likely to accidentally compromise on things that are important to them.

I don't think the solution is regulation; I think it's to teach common sense.
Everything should be transparent, so that when people search for flights, they should enter how much checked baggage they want, and all the prices they see will reflect that.

Given two flights A and B, it could be the case that A is cheaper for the person who doesn't want checked luggage, whereas B is cheaper for someone who wants to check in a suitcase.
>Journaling file systems all have transactions, do you want to run multiple actions in the same transaction? that'd be neat.

What I want is a transaction in the sense of "these actions should all succeed or all fail, and any observer should only see the initial or final state, never any intermediate states produced by the actions". The lack of such a mechanism feature leads to a lot of bugs and security critical race conditions.

For example let's say I want to do rename /var/logs and create a new /var/logs that should be used from then on. Normally I would do something like 'mv /var/logs /var/logs.old && mkdir /var/logs' (or the equivalent in my language's API). But what if the first command succeeds and the second fails? What if somebody executes 'ln /etc /var/logs' after the execution of the first and before the execution of the second command?

for windows, Everything [1] is great. It builds and maintains an index of all filenames (and some file attributes) and searches as fast as you can type. Great for finding everything if you know any part of its filename. Such a capability is the norm for databases, but rare for file systems.

It has been:

1. Wow, WizzAir, and Norweigan air has created a lot of competition on the airline front and price wars. EDIT: Forgot to mention their point to point system has also benefited many towns that wouldn't dream of traveling to Europe.

I've flow with Norwegian Air and I actually liked them. They're like the Southwest of transatlantic flights. The legacy carrier's response has been "we'll just lower our prices" and decrease benefits on all sides. (I.e. basic econ)

2. The newer carriers have had the money to lease new airplanes that are much more fuel efficient. I think that's where the legacy carriers have done does bad planning for the last decade. (They're just not buying 787s and they're depending on ERJ/CRJs)
Impressive resilience by the airframe. Good job Boeing.
They might, depending on how widespread it is. It certainly wouldn't be without precedent. Alternately, there might just be a manual effort to fix them all.
Maybe burning fuel to reduce the chance of explosion during the emergency landing? That's quite common.
Fixed security questions just seem like a flawed idea anyway. When creating an account to access a significant financial service online recently, I was given a list of some 20 security questions and asked to choose 3. The problem was that 18 of them didn't apply to me or had no clear answer of the kind that I would certainly remember in the event that those questions were actually needed to prove my identity. These things are probably second only to using SMS-based 2FA for annoying security measures of questionable effectiveness being mandated by ever more services (though the new voiceprint-based 2FA is closing fast).
Boeing planes can dump fuel, iirc.
This really puts the environmental impact of humanity into perspective for me. Not including secondary or tertiary effects, look at how much of the world that humans have physically, immediately touched! And to put this map even more into perspective, the US isn't even close to being the most densely populated. Imagine what the the maps of China, India, and the EU look like!

In the Unix and GNU/Linux world, "locate" with its updatedb database builder has existed before Windows 95.

It's part of a the standard install of various mainstream distros.

To find all cpp files, just:

locate '***.cpp'

Find all .conf files under /etc:

locate '/etc/**.conf'

https://en.wikipedia.org/wiki/Locate_(Unix) says:

"locate was first created in 1982.[1] The BSD and GNU Findutils versions derive from the original implementation."
From the paper (published in an Open Access journal at https://peerj.com/articles/5801.pdf):

"Neither reducing the use of antibiotics nor discovery of new ones may prevent the postantibiotic
era. This is because bacteria may be exposed to other non-antibiotic chemicals
that predispose them to evolve resistance to antibiotics more quickly"

Can someone who understands this stuff explain to why this is the case. Surely bateria will only evolve resistance to the specific mechanism the antibiotic/herbicide uses to attack the bacteria? Are Roundup and antibiotics using the same mechanism to kill batericia?

Doesn't antibiotic resistance come at a cost? Would not a new antibiotic that uses a new mechanism of killing bacteria be effective regardless of herbicide use?

Is secure boot redundant?
So I have a general understanding of how secure boot works but I just read the paper on the LOJAX rootkit and that made me wonder: if the UEFI provides a way for users to add their own keys to sign EFI binaries, what prevents a malicious author from manually deleting the KEK keys and replacing them? Wouldn't that make the whole concept of secure boot useless?
Sorry! Page 203 in the first PDF has a full table if registers, and that bits in them. Thanks very much for the library, and even more for taking the time to create that notebook. The captured data looks excellent. I'll hax some code to translate this data to a header file suitable for writing a driver.
The 737 (subject of this article) cannot.
There were a few quotes in the article from EFF people, but I thought the EFF was more ambivalent about private companies like TransUnion selling access to data like this. Am I incorrect or are they only critical due to the potential for abuse by law enforcement?
Woops! Was typing the above while headed for bed, knew I'd forgotten something.

Yeah, he actually had the idea that you could use the 19th C Boolean logic and switching circuits to do mathematical operations, making modern computers possible. It's disappointing that he's not better known for this, to say the least. e.g. that anyone on here doesn't know his huge importance.
AWS lets you assign multiple IP addresses to a single EC2 instance. We used to do that for SSL termination because we couldn't use SNI yet.

This was a long time ago, and I don't remember what it cost, and there was a limit. It was certainly cheaper than having multiple EC2s just for their IPs though.
