I've taken a number of Ryanair flights this year. Assigning the middle seats to non-paying passengers backfires sometimes.

I booked tickets with my girlfriend. Almost 50% of the seats were still available (this was a month before the flight), but all the middle seats were taken. We wanted to pay for seats beside each other, but that wasn't possible, because they gave away all the middle seats. When there are three seats on each side of the aisle, that means no two seats are available beside each other. So, we didn't pay, we just took the random seats, and then asked people to switch after we boarded. We probably could have paid for a window and aisle seat, then asked the middle person to happily switch, but if we're paying for seats, we shouldn't have to do that.
I flew out of Warsaw Modlin in February this year with Ryanair - the weather outside was around -20C, and they made everyone stand outside in front of the plane, while they tagged every single piece of hand luggage to put it in the hold, because of course now you have to pay extra to bring your hand luggage on board - I couldn't feel my hands after 15 minutes of waiting.

I'd love to vow to never use them again after this, but unfortunately they are the only airline flying anywhere near where I want to be most of the time.
Trolling right? If my phone can, and 86% of other smart phone users can then I'd say it doesn't really matter if iphone users can as well. They could buy a smart phone, too.
Google could encrypt the content with end-to-end encryption like Moxie did with TextSecure and SMS. The RCS content would be encrypted between Android Chat users.

But from every move Google has made recently, it seems to think that people have forgotten about the Snowden stories. So they now have ZERO interest in anything that is end-to-end encrypted, because they think they can now get away with it.

They threw an option in there for Allo, but it was never meant to be used by users anyway, and now they're killing Allo, too. I don't think they'll ever talk about end-to-end encryption again because they want all of that data for themselves.

Now, the very least Google could do for its users is encrypt the RCS messages between its Android Chat users with some kind of Noise/HTTPS encryption. That would still give them all the user data, but at least they'd be protecting users against the carriers exploiting all of that data, too. So it would be very similar to them using HTTPS for websites or for DNS, and I see no reason why Google wouldn't do this.

I still wouldn't use Android Chat because I don't trust Google at all anymore, especially after their recent interest in working with the Pentagon for developing autonomous military drones, but at least it would benefit everyone else.

Also, there was a recent thread on /r/Android, and it seems nobody outside of US cares about SMS anymore (which means they don't care about RCS either, which is basically SMS+):

Although the author has fair results with his given case, the author is mistaken the use of AI/ML in such scenario. In the example, they make the decision of "We should send emails to people who did 'case a'.". This is a pure 'instinct' by the decision maker. But in AI/ML case, this would be learnt from the feedback of the click rates etc. Naturally, decision maker becomes the AI, which actually can find interesting scenarios and exploit these behaviours to increase the desired outcomes.

Thank you very much as well for clarifying your point of view.

I fully agree with your point of view now.
This is a great "well actually" that also manages to be technically incorrect. If you change the styling in your terminal emulator, it changes the transparency of your shell (and other terminal programs).
I think he means arbitrary and unconventional, not random.
If I understand that right,

You don’t. Males and females are very, very different because of molecular biology. That is obvious. However, those differences do not make one or the other sex superior or inferior. It also does not mean that females aren’t capable of the same things males are. However, how females think is largely negatively skewed by upgringing. For example, when I see a small girl pushing a toy baby carriage, I see all Red because from experience, that’s brainwashing a little girl that girls are meant to incubate offspring. That’s an opportunity to produce a really good system bilder and thinker, or perhaps a scientist, wasted. Females can be just as good engineers and scientists as males if not better, if only they weren’t being brainwashed during their upbringing. As far as I’m concerned, that’s an intellectual atrocity.
Yes, BA have gone downhill dramatically in the last few years -- I used to be a top level frequent flyer with them

I've got a flight coming up next week with them to Nairobi, on a tired old 747, which I'm not looking forward to. In years past I'd paid a fortune for such a flight, now unless BA is at least £400 return cheaper than someone like Lufthansa, I won't fly them.

I did fly BA in January (again to Nairobi), was amazed how empty the plane was.

That is not true, as numerous documented cases will attest.

They get charged for using the gate, once they are on the tarmac "waiting for a window" they don't suffer additional costs.

It's not that they decide to "park the plane on the tarmac" it's that the interaction of various airport operational procedures make this the chepest option in certain scenarios, which is what they'll choose every time. Passengers bedamned.

In fairness though, I think though they've decided not to pursue this particular type of "cost saving" more recently.
For a lot of places in Europe, there is no other option. Ryanair has conquered connections to all smaller airports, where normally you'd need to change in Amsterdam/London/Frankfurt first, and they fly for 1/10th of the price most of the time. Yes, I hate them too, but if the options are a 2h flight with Ryanair for £30 or two 2h flights with BA for £300(or 2h flight + 5h train) then Ryanair wins 100% of the time.
> Generally, with 20% down you are leveraged 5:1. So even if your home is just keeping pace with inflation of 3%, you actually experience 15% growth on your investment.

In a 30-year loan, it’d be actually less than 15%. It’s 15% the first year.

Calculating the compounded return, it’s 1.03^30 * 5, then you raise all of that to the (1/30) power. You get a 8.7% compounded annual return, assuming 20% down. Then I think you subtract the 3% inflation. 5.7% is better than just tracking inflation, of course.

The return is different if it’s not owner occupied, since you need 25% down and there’s capital gains tax. But then there’s cashflow, depreciation tax shelter, etc.
You can't do that with some airlines though since random seats are allocated at check-in, not when you book.

It seems like an obvious loophole I would have expected other airlines to have spotted?
I've done a few challenges like that[1] but seeing that the smallest so far is over 300 bytes makes me think most of those 300 bytes are not actual code but program header overhead, because it should be doable in much fewer bytes of actual code. Once you've done these challenges a few times, you can easily estimate a rough size:

The template is 48 bytes. Add 16 bytes for an [offset,char] table. Maybe another 30 bytes (let's be generous and round that up to 32) for code to pull the commandline parameter, do the indexing and template modification, write the output, and exit. 96 bytes of code. Add 64 bytes of minimal ELF headers[2] and you're still well below 200 bytes.

I don't have an environment at the moment that doesn't do ELF files, so I just tried it with 16-bit DOS and ended up at... 95 bytes:

The longest delays I've had on Ryanair have been the shortest flights, not sure if it's just that short routes have more points for operational issues, or they just prioritise longer ones.

Recently my flight to EDI didn't leave until it was due to arrive, an hour waiting at the gate itself with no staff to update on anything (the price you pay for barebones staff on no-frills
I too was surprised by the date, given that I've been using it for the past year, at least, or more.

Apparently, it went into beta in 2014[1].

> Naive Bayes and Graphical Models are pure statistics, but they are mostly used for toy problems.

I think they just feel "toy" because they've been used with great accuracy for so long.

Complex problems are rarely solved by a single approach. The harder the problem the more likely a suite will be used, and often naive bayes will be part of that in some capacity.
I work on a product that does produce traceability. People put wrong input on forms every day, print labels and stick them into crates. They then ask us to make their code show correctly when searched. Having the wrong product appear on search and an irate client because the blockchain is immutable would generate immense problems.

Why not have auditable mutability? The audit log is the thing that should be immutable.
They are Europe's biggest airline by passenger trips, by quite a margin. I know one person who won't fly with them, but I don't believe you could inhabit such a rarefied bubble that everyone you know can and will avoid Ryanair every time.
Ask HN: Uncommon but attainable programmer skillsets valued by employers?
Was having a discussion with a programmer when this popped up. He has applied to various (remote) positions without success. (I tried this as well earlier, but gave it up to found a startup)

I use Mint but generally, am not trilled with it.

1. I have a hard time managing my bank account AND my main credit card. Mint seems to think me paying off my credit card bill is another expense, however Mint already tracked the CC charges so basically Mint thinks I run a massive loss every month (yes I've tried fixing this, multiple times)

2. Other than reviewing your newest transactions, and the occasional useful bill/fee reminder, I don't find much use for the app in regards to financial planning or analysis.

3. I don't like how Mint is basically used to slurp up my data, and sell me credit cards - it's obvious now how little they care about making it truly useful. The app has been in existence for years and barely nudges forward besides new UI.

The thought of manually tracking my expenses however is too much work. I find it hard enough launching the Mint app regularly to allow it to download my latest transactions.

Interesting, so you think it comes down to "I'm paying $x/year for you to be at the school, you are forbidden from taking part in dangerous activities". If so, that's really quite sad - university should be a time where you transition into adulthood and are responsible for your own decisions (good and bad).
Don’t hear the naysayers, $5 is a good price for it, frankly $4 would be even better not because it’s cheaper in so much as it’s less than a round number that could be used as a mental barrier.

I can imagine a lot of non techie creatives using this to keep focused on long projects.
If a company raises prices 'because they can' and people keep paying, that is just how markets work.

In some sense, this leads to a better allocation of seats, as it allows those who desire some seats to pay for them, whilst those who have to preference get a cheaper flight.
Now, people who used to be fine with the dice-roll of not paying get a worse experience. But this comes with the upside of those who really wanting the seats having a better chance.
And what exactly is not "done right" about that? If it displays the information it's supposed to in a clean and organised way, and loads as fast as any other website, then I couldn't care less if it's a '90's table layout' or using whatever the hot new JS framework is.
Neat. I look forward to seeing an awesome post-mortem in 2 years when they abandon this project.
That's true. I got interested in investing in ICOs just a few months ago. Currently I try to read more info about new projects to reduce the risks. Recently I found new info about Seele ICO, I read its review at https://icopulse.com/blog/seele-ico-scam-annoying-misunderst... about scammers who lured about $ 1.8 million from potential investors in Ethereum in early February 2018, using the names of the creators of the project. It was really promising project. I think such an unpleasant event gives all investors the opportunity to buy tokens at the starting Seele ICO price.

I once worked with a hosting provider whose battery backup was that every server was actually a second-hand thinkpad.
The PIC16 is probably the closest - all arithmetic has to go through the W register. Confusingly PIC calls all internal memory "registers", but really it's more like a one-register machine.

The Z80 routes most arithmetic through its A (accumulator) register.

The inheritor of this is the X86, where there are much fewer register limitations but tradition and the lettering remain; (E)AX is the calling convention's first argument and return parameter. And the article itself details that you can get shorter opcodes by preferring to do arithmetic through EAX.
Southwest is an interesting comparison actually.

>> A lone woman walking in the middle of the night was as common a sight as
Sasquatch; moonlight pedestrianism was too dangerous for her.

Mnyeah. Also known as walking alone while female after nightfall.

I used to do that when I lived in Athens, Greece. There were two distinct
periods of it, because I went through a phase where I had a decidecly
gender-ambiguous appearance (short hair, combat boots, jeans and t-shirt) and
another when I dressed more typically feminine (think your mom when she goes
to the hairdresser's).

When I looked like I could be a boy with weird hair, I thoroughly enjoyed my
nighttime jaunts and I never felt threatened or harrassed. I walked around the
seedier parts of town, where the drug-dealing and the sex-working happened-
because that was the point, to see the night life that crawls out of the
woodwork when all the decent people are safely sleeping at home. Despite all
that I never got into trouble. I guess I looked like a bit of a freak so folks
probably assumed I was out for a fix or something. But who knows?.

When I looked my most femme, the situation was completely reversed, even
though by that time I was bored of the sleaze and stayed firmly in the
better-lit, higher-income parts of town. People would stick their heads out of
moving cars and yell obscenities ("Hey baby, are you making house calls?
MWAHAHAHAHA"). If I stopped, like to sit at a bench for a few minutes, shadows
would detach themselves from the background and slowly amble towards me,
nonchalant like, until I felt insecure enough that I had to get up and march
away. Every single man I met would consider it their obligation to hit on me,
one way or another- tell me how pretty I was (in the dark, sure) offer a ride,
offer to buy me a drink... strangely enough, nobody ever offered to buy me a
souvlaki which is what I actually was after most of the time.

Note that this was Athens city in the period between 2000 and 2005, long
before the immigrants started coming in. I'm just saying. Those people who
made it a pain in the ass for a woman to walk alone at night? Plain,
middle-class white guys in a country with a rate of violent crime among the
lowest in the world.

Well anyway. There you go. It sucks to walk while black, it sucks to walk
while female, also- or at least, while recognisably so.
The article specifically says that there is statistical evidence showing that Ryanair does, in fact, preferentially allocate base-fare paying users to middle seats. Though the article does not explicitly say that the evidence supports a particular variant of the algorithm, your particular alternative does not seem to alter the underlying reasoning here, which is that if you check in late enough, all the middle seats have been allocated. Once that happens, you are not going to be allocated a middle seat, regardless of how the airline allocates the remainder. (This could, however, change your odds of getting a middle seat earlier in the process, and whether a later check-in leaves you more prone to being bumped (which I assume Ryanair does unless it is forbidden by law) is another issue to consider.)

Update: I see that Ryanair does not overbook, which puts some perspective on the complaints about it - I don't care about meals but I do about the risk of being bumped.

Update 2: I overlooked one part of the alternative algorithm, but I think that it actually makes it less likely: if they are holding back middle seats on the chance of upselling to later arrivals, where are they going to put those people? It seems that they are likely to end up with a bunch of middle seats with no chance of upselling even to passengers who would have done so, or possibly having (even more) disgruntled passengers who paid to choose but got a middle seat anyway, depending on exactly how this scheme works.
I would argue, that YAML (which actually is a superset of JSON) comes closer to JSON in being friendly for humans.

That has changed. Both PDP Media Remotes for PS4 can turn a PS4 on. Still proprietary, but they're technically not PS4 controllers.

Reading from Amazon reviews, also the PDP PS4 IR Receiver For Logitech Harmony Remote Control Devices can turn a PS4 on. But I can't confirm this as I don't own one.
You definitely can use it for leg space, or rather, for knee space.
You're not going to stretch your legs into the isle, but just poking out your knee a bit can give much desired relief for those with long legs.

For me on a budget airline, this tends to be worth it. Even more so if the person in front of me decides to recline their seat.
>Are you better off:

This is the part I don't get. That would require renting to be cheaper per month than having a mortgage, yet it will always be more expensive for the same property because the landlord is paying the mortgage* plus marking up the price to make a profit.

*Or at least charging the equivalent market value since there will be other landlords in the city who are paying a mortgage
Stop believing the marketing, they can say message is end to end encrypted even if they encrypt it twice, once with apple key and once with "end" key (actually it is more complicated, but for the sake of this debate it is good enough, for a simple algorithm, check bellow)

Before you start downvoting spree, read this:

For Apple:

https://www.tripwire.com/state-of-security/latest-security-n...

For WhatsApp:

(encrypt data with random key with symmetric encryption algorythm (AES,...), which is then encrypted and stored with the mesage twice. Once encrypted with recipient public key (asymmetric: RSA,ECC) and once encrypted with apple public key. This way you can say that you are having end to end encryption while you can still read everything and you can also use all the nice words in marketing material, AES, end2end, RSA/ECC,...).
I see the resemblance but I think it's somewhat different in this case.

Something like Docker brought to light tech that many developers weren't familiar with but that existed before. But it actually accomplished concrete things in a very short amount of time.

Blockchain on the other hand is attractive not necessarily to developers, and it so far has promised a lot more than it has actually delivered. We see talks of huge figures and white papers and half finished products where the important features are coming in "the next milestone".

This is draining investment from others more viable solutions and creating the possibility for any blockchain startup to somehow shoehorn the tech into a product and insert themselves in a market of their choice.

IMO this is the wrong kind of disruption where potentially everyone loses in the mid to long term.
Agree Flybe are not always cheap but I find them much more laid back about checking in and such.

I recently had a friend visit me in Spain from the UK and he is a very nervous flyer. The way they treat him was absolutely commendable. I doubt he'd of even got on the plane with some other airlines.
I often suspect with BA, that they actually purposefully make the economy experience worse than it economically needs to be, so that the difference with the more expensive tiers can be exaggerated. Often a fairly dismal experience, but their in-flight food is usually very good.
