Expedia isn't checking availability, a middle man is, (one of the three GDS).

The middleman isn't checking availability every time because there's a cost to ask the carrier. And if you ask too much they will rate limit or deny you which means you get no availability.

The middleman is a price aggregation person, and tries to find rates and routes using all the rules the carriers specify.

Sure you can buy tickets directly from AA or UA. But what if you want to fly a connection that has both. Do you think AA wants to sell seats on someone's else plane?
I wish I had a more authoritative source, but this matches my understanding: https://news.ycombinator.com/item?id=19512161

As a side note, it’s really unfortunate that we won’t get an NTSB-level (both in detail and widespread respect for the organization) report on what went wrong and how it happened. I’m not sure the Ethiopian and Indonesian authorities will really (be able to) dig into MCAS and all the details of its development as deeply as we’d like. I expect that some of the reporters covering this story will write books (Dominic Gates and Jon Ostrower in particular), and those will be the most authoritative accounts.
"it wasn't as convenient but it worked" - this is the story of every single dead product. Zunes were less convenient than iPods and iPhones. Books are less convenient than Kindles. AltaVista and Yahoo Directories were less convenient than Google.
Having 6 months to fix it would have been fine.

Instead what they've had is 2 weeks to fix it for 6 months, which is a very different kettle of fish.
Somali does have this sound too. I am yet to come across another language with the same.
they are a very good judge of whether the programmer can do complex problems (but still simple enough a solution to do in an interview setting).
Ask HN: Critique My SaaS Idea
So elearning is huge. Everyone and their moms want to create and sell online courses.

I'm aiming to build a white-label "Shopify for courses," with only the most basic features (i.e. online course store, members' area, course management back-end, payments processing), and using freemium "Powered by" backlinks to acquire customers (to start). Plus posting on forums and Q&A sites. And targeted at aspiring solopreneurs, not established teachers/instructors/coaches. So these people who still have a day job, not serious full-time course teachers, but want to create a passive income stream or monetize their passion while sharing their knowledge to an audience.

I'll charge $9/mo to start to appeal to this segment (maybe a commission % too), where other solutions start at $39/mo. It probably won't be the most robust solution, but it does allow the aspiring solopreneur to: 1) have their own online course store hosted on their own domain with their personal branding, 2) which is optimized for conversions, and 3) where they don't have to worry about payments, setting up a site, etc. Only on teaching and selling their courses.

Do you think this is a feasible idea?

Is it too crowded and hard to differentiate/niche down?

If you're considering teaching a course, would you be interested in this product?
I hated my HP Envy, because it kept breaking, but...I guess I do have to give them credit for it being fixable. I replaced both fans (in separate incidents), the keyboard, and re-seated and taped the screen cable, in the nearly three years I used it as my primary laptop. It lasted a lot longer than the Dell that followed it, which broke in ways I couldn't fix. My stance on HP has softened, because I've sort of seen that they're not alone in making crappy stuff (and, no, Apple is not immune), it's kinda the norm these days. I'd kinda sworn off of them forever...but, they're cheap and I guess they're about par for the course in terms of today's laptop longevity. Being repairable goes a long way to making them likeable again.

What we should have is an open, freely accessible meta-information database of things like, whether user X liked/disliked, what other page/sites linked to this site, what their admins ranked this site as, if they did, etc., etc.

Then we have individual engines that take this data and choose for the user what to display for that user only. So if the user is unhappy with what they are seeing, they simply plug in another engine.

Probably a block chain would be good to store such a thing.
Yeah, this is a thing. So many reasons but essentially the initial request returns a fare that is invalid when you try to book.

But there's also issues where the carriers play games by reserving flights for specific customers. By customer I mean the travel agent or website.
I'm currently using Firefox on all devices as my primary browser, but there is a single feature that I've gotten used to in Chrom* browsers on mobile - 'pull down to refresh' - that looks indispensable to me, and I'm planning to move to Brave on mobile just because of that (already replaced Chrome with Brave on Desktop as my secondary browser). Yes, there are add-ons to do that on mobile too, but they are all inconsistent and half-baked. Chrom*'s built-in pull to refresh is very smooth.

It would be a bit sad if they made them repairable because they fail so often.

Being more serious I’m not sure this is considered in the debate about repairability. If Apple soldering memory to the motherboard is more reliable than using a socket is that better or worse for the life of the product.
I did, and I searched for several random 4-6 word phrases in the Atlantic article from the Wikipedia one, and I didn't find anything making it obvious much of the content is an exact mirror.
If the Republican party is representative of most Trump supporters, they are very obviously authoritarian, far-right nationalists. I don’t see how you could possibly think otherwise. Given how much graft, debauchery, hypocrisy, and cruelty has been shown by this administration, what sensible argument could still be made for supporting Trump—unless the answer is purely “power?”

I have also not seen a shred of evidence that Trump supporters “hate fascism,” unless you count the various boogeymen that they have labeled fascist (antifa, socialism, feminism).

I refrain from using “simply” or “just” unless I am the person expected to design or fix the problem. Ahead of time. Saying after a disaster caused by the most powerful earthquake ever recorded in Japan[0] that the solution was “simply” to do some coincidentally simple-sounding thing is not credible.

The increasing of the global temperature is really dangerous and humanity seems to do nothing.

It is like a human body if its temperature changes a few Celsius degree from its normal temperature, it is the fever.
If the person has a fever and it increases a few degrees, it might mean the death of the person. We are killing The Planet, it is a Climate Crisis.

The NTSB will issue a report. It's an American made airplane involved in an accident, so they are required to investigate. They just don't have primary jurisdiction over the investigation, per ICAO rules.
Over the same period the mods handled 83,000 cases.
Despite the 737 Max fiasco, airplanes today are far safer than ever before. Since 1970, annual deaths have been cut by >80%, while air traffic has increased by a factor of 10.

Cars have seen similar improvements. So have food hygiene, workplace safety, and most any measurable safety record I can think of.
Yes, which is why it should be illegal to build non-repairable laptops and phones. This is exactly what a market failure looks like. Everyone racing to be the prettiest, at huge environmental costs.

SF has what must be the most valuable database in the world. It must be worth far, far more than their market cap.

That I have not heard of anybody mining it must mean they have a really good handle on how to keep such activity secret. Because from a business standpoint it would be irresponsible not to monetize something so valuable. Anybody using it must realize that has to be going on, at some level.

Maybe they only license out access to spooks -- NSA, Mossad, GRU. (What is the Chinese one called?) Those have access to unlimited cash, and know how to use spooking to get more.
I thought the queuing algorithm for banks was to line up transactions so the largest go through first to increase the opportunity for overdraft fees.
depends. one cannot spend the whole life dissecting and acquiring all facts, sometimes we just delegate thinking, but the result is that it leaves us unable to defend the opinion because it wasn't our to begin with, regardless of how much the case built by the third party was compelling and fact based

so for example I've read an interesting opinion about game of thrones and why the latter season were less interesting, and it made the case that the story shifted from sociological to psychological drama and it set a completely different tone - some day later there was a similar debate on a forum but while the position was interesting I didn't had the ability to articulate it because a) it isn't my field of expertise and b) I didn't spent time dissecting the issue myself building an opinion, it was delegated.

and so I just wrote down two lines - hey guys check out what this author wrote on the subject - because it was interesting and it seemed well checked and I wanted to see if somebody was able to point out faults in the reasoning I didn't catch because of my limited expertise in the matter

sometimes who arguments by linking doesn't want to convince anyone, but wants to proxy debate an opinion piece by collecting and contrasting other opinion on the subject
Capping individual participation does not make new low skill jobs. When you cut all low-skill jobs you are always going to increase the number of people below the cut as not everyone is going to successfully re-train into a job that won't soon be automated. Making new high-skill jobs does not help them.

I don't see a convincing solution other than UBI. Sure, it's untested, and the transition is going to be rough. But capitalism isn't going to stop automating jobs. The jobs are going away and I think the easiest way to prevent the negative effects of having a big chunk of unemployed young men of fighting age. When given a choice between extreme poverty and fighting to overthrow your government, the choice is obvious (Syria for example). When given a choice between a comfortable lifestyle (if you budget well) and fighting to overthrow your government, the choice is obvious.

Part of the reason poverty sucks (in a developed country) is that you have to work long hours for barely enough money and then cook and clean and take care of your kids / elders. If you don't have to work, the effective poverty line drops significantly.

Our society already has the wealth distribution issue, and seems to be moving forward without crumbling. If we can drop 40% of jobs without decreasing overall productivity, I don't see why we have to make something up for the unemployable to do.
I suspect just randomizing the first 20 or so results would fix most problems. The real issue is people putting effort in to hitting the first page, so if you took the benefit out of doing that people would look for other ways to spend their energy.
It's not just audio requests btw. Google regularly serves ads that automatically redirect users to scam sites. A client I work with gets hit with that about every six months. The ads are targeting only mobile users which makes it even harder to debug. There's nothing a publisher can do to prevent this but disabling Google Adsense completely. There is no support from Google. After a few days, a week maybe, Google disables the malicious ad (or they see that the credit card didn't work) and it stops.
I did it a few times. When I google Dr. Paul Drago. I do seem some of the articles. That may be because I've click a few of the links and have done the search a few times. Also The https://www.lipstickalley.com/threads/plastic-surgeon-paul-d... link also appears on the second page now.

I primarily use Firefox on my desktop, but I use Brave on mobile. It seems somewhat easier on the battery than Chrome, which would make sense being as it's blocking content that can be CPU intensive.

You might like it, though. I've used Brave's mobile sync and it works for bookmarks across devices quite well. It's surprisingly simple to set up, too. I don't fret much about forgetting whether I opened a tab on my phone or desktop if I remember to bookmark it.

That said, I still use KDE connect to send links to my primary Firefox instance and vice-versa, but the bookmark sync is in some ways more convenient. I'd imagine they'll eventually synchronize more things, like tabs.
I've had quite the opposite experience there. I eventually settled on Brave because of my browsing habits. In particular I tend to have several windows of a browser open with dozens of tabs a piece and tend to rarely reboot my machine. Capping all this off is that I enjoy playing chess, which relies on millisecond responsivity. This [1] is a screen cap of the current performance usage of Brave. It's completely negligible, and hasn't been restarted for days. The higher memory processes are exclusively from pages I am currently using with extensive content loaded on them.

No clue about Safari but Firefox dies under these conditions, and I'm not interested in Chrome given not only Google but their 'vision' for the future of that browser including native anti-ad blocking. Opera was okay, but I enjoy the privacy features of Brave. Native ad-block, tracker blocking, etc that can all be customized per site in literally two clicks. Lion->Third Party Trackers for instance would allow me to enable third party trackers exclusively on Hacker News if, for some reason, I wanted to. Pretty cool stuff.

I think this arises because we can't really model intentions as they involve irrational, subjective, qualitative preferences. .. That's to say, I completely agree with you.

i get the feeling that Go is quite well rounded. like good overall but best at none.
I think that attitude is part of the problem. If you're competent, it's usually much easier to find a new job than it is to take on entrenched cultural and funding problems that create risks. This further entrenches the problems by driving out dissenters, and if you work for a regulator, the 'creative destruction' of the free market can't fix it either.

Hey HN,

Do you know examples of productized service businesses?

Thanks!
Google will pretty much always put the domain as the first result for things that look like a navigational search. I imagine closely matching a real, known url that other users click on is a strong ranking signal.
Fukushima survived the earthquake and even survived the tsunami. The generator got wiped out, but even that wasn't what ultimately led to the disaster. It was that the battery backup eventually ran out of power (not unexpected) and the connectors for recharging it were old and of a format that isn't used any more. There was no way of recharging the battery backup and so the pumps eventually failed.

It's one of those problems where there are literally a million things that could go wrong and since the emergency system is not used normally, it's easy to overlook a critical problem.

So I agree with you. Fukushima was not a design error -- or at least not a design error that could have been reasonably fixed at the time that the reactor was originally designed. It was an error in maintenance. Obviously better to have a design where loss of power doesn't cause a melt down, but I don't think that these were available when Fukushima was built. CANDU reactors existed at that time, but I think they were still considered experimental. Pickering came online in 1971, so basically at the same time as Fukushima. I'm not familiar with other passive designs, so possibly someone else can make an observation.

But basically, as far as I can tell, Fukushima was a reasonably normal nuclear power plant for the time it was designed. The Air Max seems to have suffered from problems because of design decisions that are not considered normal.

While this is certainly technically possible, I think this presumption -- which I see a fair amount around HN -- is at the least somewhat dubious. There's an extremely crucial difference between the Mac and the iPhone/iPad that this argument downplays at its peril: the iOS ecosystem has never been open in this way; the Mac ecosystem has been open in this way for over three decades. Customers do not tend to react well to having things taken away from them.

What's the cost of not just individual users but whole companies moving off the Mac platform en masse? What's the cost of a press firestorm so intense it'll make the butterfly keyboard shitshow look like free passes to Disneyland? Are you sure so many users would just docilely acquiesce to "guess I'll have to re-buy all my software all over again, herp de derp?" Because for this plan to make sense, Apple needs to sell a whole, whole, whole lot of software to make up for every single person who decides this is the straw that breaks the camel out of the habit of buying $2500 laptops every three or four years.

The bottom line is that I don't think attempting to lock the Mac down to the point the iPad is locked down makes business sense. (I'm not convinced keeping the iPad locked down makes business sense in the long run, either. But that's a different post.)
You must be talking about private browsing or the native TOR windows. No history at all is retained for those windows and so restoring closed windows/tabs is not possible. For regular browsing sessions tab restore and session restore work 100%. I have plenty of sloppy tab clicking experience to prove it!

I had to manually delete every video in her history to fix that.
It was just an example. What applications require hardware support that isn’t baked in? Surely the Mac isn’t being used in an industrial space with niche one off instruments? The point is more things are moving to userpsace and Apple is controlling the kernel as, I think, they should.
IETF RFC 4198: Urn Namespace for Federated Content (2005)
It's interesting to see block list creators more or less reinventing all the tricks that network-security regex implementation people invented 10-20 years ago. One wonders whether they might do better picking up an off-the-shelf regex implementation (e.g. our own Hyperscan, or for those who must must must have something in Rust, the engine from ripgrep, which I believe is just called "regex" :-) ).
How does one become financially independent?
It really depends on the ads, I believe. You can't actually read that page when the ad people go all out. There will be a video playing in the background of the page, there will be animations in content and they will throw in a pop over saying if you really, really, really don't want to save $10.

The Elitebook x360 G5 and G6 are pretty common in our org. The G5 had a few problems, but the G6 (which I have) is really nice.

The only design flaw is the (non-)docking station setup doesn't give it sufficient cooling, and the location of the power button makes it too easy to accidentally press.

Fortunately you can switch so a single press of the power button doesn't shut down the OS. And we're 3D printing desktop supports that fix the cooling situation.
It is okay, it breaks often though, e.g. versions after 1.2018.03 does not work with directions anymore: "A -left-> B"
