Europe has airports ranging from some of the world's biggest (LHR, CDG) to some of the smallest.

At some airports, all flights will be international (e.g. Shannon). At others, all flights will be domestic or within Schengen.

Some airports are almost entirely used by budget airlines (London Luton), others have very few budget airline flights (London Heathrow).

That leaves plenty of flexibility for how the airport is operated. I'd expect a gate printed on the boarding pass as the larger airports with longer, non-EU flights. I'm not surprised when a Ryanair flight only announces the gate a short time before departure, since they have such a short turn-around time everything seems to be last-minute.
Your first line of defense will be conformal coating. There are various options here. Easiest to apply for DIY electronics would be in spray form (such as Electrolube HPA200H spray)

However, if you have an RF component and/or RF circuity in your PCB, you should be careful with conformal coating. As the frequency goes up and impedance requirements gets tighter, conformal coating becomes harder and harder to use, because it alters the RF circuit behavior. Also, obviously, you should not be coating certain sensors (pressure sensors, humidity sensors, etc).

Your next line of defense is your enclosure. Ideally, all your connectors should be IP67 or IP68 rated, and you should place your PCBs in an enclosure which is itself IP67/IP68 rated. This is usually achieved by using a gasket and designing the enclosure with a proper gasket opening.

If your device is going to be exposed to sunlight, you should make sure that any active IC in your system will not exceed its operating temperature. Metal enclosures exposed to sunlight will heat up considerably. You may want to think about a cooling solution, based on your power dissipation (enclosure with fins, etc).
To be fair, this was in Christchurch not too long after one of the bigger earthquakes but I got severely messed around by the ambiguity of some of the road signs, to the point where I once ended up on the wrong side of the road.

I personally avoid the mobile app. I have no data plan on my phone, and airport WiFi is not exactly known as the best (or safest). I also have this (probably unfounded) fear of my battery failing and having to go through a bunch of extra effort to get a printed one anyway.
>You don't usually have nice JSON endpoints, so you'll be doing a lot of HTML parsing

That is changing. Most scrapers haven't caught on, but the more modern things airlines are pushing out (their mobile sites and native mobile apps) often have really nice REST/JSON api interfaces. The scrapers are often still scraping the old desktop site which will be the last to get that underpinning.
I think those conflicts exist in all so-called "teams", but in Agile those conflicts become sublimated by a grumbling about "process" on a sprintly, if not daily, basis.

If your plan, on the other hand, is to have three people develop three separate parts for a year, and then think you are going to stick them together and release in two weeks, people can avoid interpersonal conflicts entirely for a year, after which there is a crisis, which is often survivable by the participants because there are already so many chips in the pot...

> People desire a structure that allows them to abdicate responsibility.

s/People/Managers/

In many of the cases I have experienced, agile breaks down into an excuse to not plan ("Requirements just slow things down!"), and the elements of it that would drive success are ignored.

So often business leaders just want shit done, and when the technical types warn about reliability or technical debt, there is a lot handwaving. Thus short attention spans see agile as a way to justify shortcuts. When this happens the result can be worse than a poorly executed waterfall model.

Agile works when all the proper elements are used, just like any other endeavor, and it fails for the same contrary reasons. Developers become frustrated when yet another path to accomplishment is blocked.

Disclaimer - Am technical manager. Have watched business peers shortcut to failure. Have fought the battles and lost. Frustration apparent.

It's very much not trivial, though. Given two solutions to a coding problem, how do you objectively determine which one is better? More importantly, how do you objectively tell if either of them is good enough? Or if they're poor?

>How do you mean, suboptimal? The fully generic version is 2 lines of initialization more than the restricted version.

I.e. a 200% increase in code size! Now imagine that throughout the entire code base.

> Is 2 lines not an accepted tradeoff for being able to change the engine, and crucially, to draw numbers from any distribution you want?

It is a complete waste if you don't need that functionality. That is the point. Generic solutions solve problems you don't even have, and that comes at a price.

>Furthermore I bet the generic, templated version is as small and fast as a naive implementation. It's all templates so it's all static code generation.

You kinda missed the point. I did not even specify how random(a,b) was implemented, so making statements about the speed of the compiled code makes no sense here.

C++'s templates are another nice example of the cost of generic code, though. They are one of the primary reasons why compiling C++ is so slow / resource intense. They have to be instantiated at compile-time again and again and again.. which is a non-trivial process, much slower to compile than a plain non-generic function call. Also they are historically infamous for producing hard to understand error messages.

I'd be interested: how many OFFERS did she get (or plausibly could have gotten)?

It seems easy to read this article and conclude that a junior developer in similar circumstances might be picking and choosing between working at 20 different companies.

The reality might be more like picking between 1-2, and the "reasons [she] didn't work for them [the rest]" were THEIR reasons, not hers.
A humidity sensor, coated with conformal coating, will simply not function properly.

If you need conformal coating on your PCB, most sensor manufacturers will recommend you to cover the top of the sensor with some material (for example, Kapton tape), apply conformal coating to the PCB, and then remove the tape.
I think it's useful for people who don't speak a local language -- the standard-ish format is easier to handle than an app or website.
Let's look at this from a tired traveler perspective. Not sure whether you had the joy of being on the other end of a transoceanic flight but typically by that time you have been up for too long, stressed from packing, passing security, immigration then sitting 10-12-16 hours in an overpressurized dry aluminium tube.

Your brain wants to shut down. You are staring at this piece of paper which has the flight number, the gate number and the seat number in roughly the same size, the same font and in every which way visually the same.

I did get dangerously close to mixing up my gate with my seat. More than once. It's an atrociously bad design.

And it's not that hard to improve. All it needs is more folds. First fold, flight / gate. You don't give a shit about seat so hide it. This doesn't require new printers , new standards or shit. Just one more fold in the paper. Is that so hard?

Why did she retract her applications from companies during salary negotiations just because of the way the ask for first bid was phrased? ("How much are you expecting us to pay him you?")

Seems like she should have asked for more than she wanted with the expectation that the company would make a lower counter offer.

I mean, a job is literally money in exchange for services. It's reasonable for both sides to talk about what the exchange rate is going to be during the interview process.

Edit: she admits that she is a junior developer and often doesn't know what she is doing in her post. It's reasonable for this to be factored into her salary. None of you downvoters have yet to provide an answer to my question of why she withdrew applications because of the way salary negotiations where phrased to her.

How did you reach that conclusion?
No, because we have no idea what the bounds are. We don't know what dissimilar life could possibly look like.

If I send you to a junk yard and say "Find my old microwave" can you do it? You'll probably start by looking for things that look like what you think a microwave looks like, right? But what if mine looks different?

We know life is probably somewhat rare in the universe, at least compared to the raw number of planets. But we know that Earth ticks all the right boxes to generate life, despite that adversity. So we look for things like Earth because it's more likely to be productive than a blind search with no bounds.

I really dislike comments that are negative about design when someone has spent a lot of time researching the problem and the commenter has not. With that said, here is me doing that exact thing:

I agree with usaphp. With equal visual hierarchy, it's dismissing the fact that you care about some items 0% of the time and some items 100% of the time. And this difference between these states can change in minutes. For example, I don't care at all what my seat assignment is until I'm on the plane. I don't care at all what zone I'm boarding until I'm at the gate. I don't care at all what gate it says because gates change all the time. Even if I used mobile kiosk for check-in and it gives me a gate, there's a non-trivial chance that by the time I get to the terminal, that gate has changed. I do not rely on the gate assignment on my boarding pass, ever.

Similar items are not grouped when they should be: such as boarding time and gate.

And the font is not glance-able. It's a nice font that takes little width, but unless they start changing code share codes to "DL50,381,172", there's a ton of extra space that could be used. (of course whitespace is valuable too, but squishing information together for the sake of squishing it together is not a wise design decision.

Regarding someone's comment about color/shitty printers - this kind of design would require two designs: one b/w and one color. The strength of the reds and blues would take over the important information.
Are they truly separate alternatives? Stopping sexism without redressing the inequalities that have arisen so far still seems pretty unfair. It would benefit future generations of women while telling current women they just have to put up with the results of past sexism...which is sort of sexist, itself.

> Is the illegality of the other activities really relevant if they can't be prosecuted?

Normally, no (which I said explicitly in another comment here). In this case, the activities are linked. There's no need to evade taxes if your income isn't illegal.

Even so, I don't subscribe to the argument that it's entirely a good thing that we prosecuted Capone for tax evasion. We were unable to prove the actual criminal activities, so we instead looked at the fruits of those activities and used that.

Another way to look at it is that the justice system completely failed initially. We couldn't build a case for the major crimes, but we could for the lesser crimes. He was still guilty of both (this is of course assuming his guilt).

In Shkreli's case, we failed to prosecute originally because it's not a crime. The current case isn't related in the same way, and linking them and punishing in the latter because of people's perception of the former is akin to levying a harsher sentence on someone because of their interracial marriage in a region and time when that was legal but frowned upon. Social pressure unrelated to the issue at hand should not be relevant in court. Even if it's related to the issue at hand in the case, it should be restricted to sentencing (where it likely can't be removed anyway).

Many years ago I did a webcast for Moz (formerly SEOmoz) on the topic of how to find things to write about. The webcast is behind a member wall (free to sign up I think) but might be helpful to you[1].

Other tricks I use to come up with things to write about: search Twitter/Quora/Reddit for people specifically asking questions related to what it is you want to write about (e.g. "automatic habit"). Then break each question down into its fundamental components to create a more complete set of topics, asking who, what, where, when, why, and how of each specific question you encounter. This way one question ("What types of habits should be automated") can very easily become several ("Who benefits most from automating habits?", "Where does automation take place?", "When should someone consider automating habits vs. not?", etc.).

Of course Bay Area people hate ideological diversity? As opposed to religious North Caroliners? Are you telling me that Bay Area culture should look to North Carolina to learn a little more about what diversity and tolerance look like?

What's your sense of scale here? What does ideological plurality mean to you? What does North Carolina secularism look like? Does North Carolina have a cultural embrace of secularism? Is the bathroom bill a good thermostat for what issues have play in North Carolina?

I would argue that the Bay Area is very fertile ground for diversity. The Bay Area Christians build enclaves of high quality here, bastions of middle-to-high SES wealth, aspirations, and sensibilities. They stand as quality in contrast to the community right outside their legally protected walls.

I would say that the Bay Area is a cutting-edge experiment of secularism and plurality that the world is watching.

Taller buildings need more shafts because they'll spend more time in transit so unless the occupants have the patience of saints you need lots shafts to keep wait times down. Eventually most tall buildings setup sky lobbies and express lifts that only service a certain range of floors to keep wait times down during peak hours.

It's really rough in convention center hotels when a huge convention comes to town a lot of the time it's practically impossible to get an elevator down from the middle floors because it's already full from the floors above you.
That sounds like a different definition of "perception". The philosophical, psychological, and neuroscientific fields don't use the word like that. To output an object map wouldn't be described as the same thing as "perceiving" the object.

I do something similar to this on PPC campaigns, but not for the purpose of blocking IPs. Bots tend to come in waves from a given site. If more than X% of clients from a given referrer wind up on the fake link (or other techniques show that the clients are bots), my code can automatically suspend the display of ads on the offending site for a period of time. If it continually happens, then the site's owner is the likely culprit, so I have a threshold at which that site is automatically and permanently blacklisted from all of my campaigns.

I have found that advanced bot mitigation is the single most significant determining factor of PPC ROI, which is a sad commentary on the current state of the paid advertising ecosystem.
Haha, the HN post about Facebook has a very interesting comment which mentions the internet "a decade from now":

> It is just a joke that Facebook could be valued at $6 billion. An absolute joke.

> FB has 30 million users, and that's not considering potential duplicates.

> The number of active users may be even smaller than that, and some people like I only log on once a week or so.

> If FB gets sold for $6 billion, that means the new owning company would need to make $500 million a year for 12 years(!) to break even.

> Frankly, the Internet will probably be drastically different a decade from now.

> FB doesn't even make $50 million a year, who in their right mind thinks that they will all of a sudden make a profit off Facebook by spending that much money?

> I swear some of these big companies just like throwing money at things. Yes, the dot-com bubble is here once again.

If the elevator ascends too fast, riders' ears will pop, and some people, especially those with colds, will experience ear pain. Some high speed elevators (Tapei 101, at least) pressurize the elevator cab so they can control the rate of air pressure change. But that runs the cost way up.

Doors have to close slowly for safety. There's a limit on how much kinetic energy (7 foot-pounds, from memory) can be in a closing door. Opening can be much faster, and on high-speed elevators, it usually is.

At the destination floor, there's often a delay for precise leveling. Position feedback for leveling is just limit switches until you get to the really fancy high-speed elevators, so it works by shifting to slow speed and inching until the switch trips. Fancier elevators used analog optical systems and inductive systems that gave an analog signal of leveling error. Here's a modern elevator position sensor, with a bar code strip running the height of the shaft.[1]

Precision position and speed control of large motors was really hard in the 20th century.

It's worth mentioning that car GPS navigation explicitly calculates how plausible each GPS reading is, based on a combination of other position signals and basic physics modeling, and discounts anything that sounds too crazy. If it didn't, simple things like tall buildings would be huge problems.
ULTIMATE TRICKS TO GET CHEAP FLIGHT TICKETS
At this point you start doing locals (multiple elevators per shaft traversing only a subset of the entire building) and express (elevators skipping floors, usually between ground floors and various "sky lobbies" at 30~40 floors interval).
