Ask HN: Data Scientists/Analysts in Aviation
If anyone has experience working with small airlines or in aviation tech, i'm interested in your thoughts:

- Curious to learn more about the types of queries and data analysis commonly run at airlines? From what I’ve heard, the focus is often on customer loyalty, experience metrics, and ad hoc stakeholder requests, typically visualized through Tableau dashboards.

- What’s the best way to access airline data for building predictive models?
> even in places like NYC

would be curious to hear why this specifically surprises you. Is NYC your idea of a gold standard for honesty?
Show HN: MassApply – Human Assistants Apply to SWE Jobs for You
Finding a new SWE job sucks. I know from going through several grueling job hunts myself how exhausting it can be—especially if you're juggling a day job or coursework.

One of the biggest pains in the process is having to send out endless applications. In 2024 many candidates have to submit hundreds of applications in order to land a role. Filling out applications is a time-consuming chore that could be better spent on interview prep, networking, or watching paint dry.

I created MassApply to relieve SWEs of this tedious duty. MassApply handles the bulk of applications for job-seekers. Candidates fill out a form with their preferences (title, location, minimum TC, etc.), and we submit applications on their behalf.

We’re offering a free beta of 40 applications to select users. Sign up on our website if you’re interested!

Feedback and questions are welcome!
The biggest red flag here is that Invisalign is not a cavity treatment. If she needs a treatment plan for cavities, that plan should include some treatment for cavities.
Not only in English. My local newspaper (in Trondheim, Norway) shows its name as Adresſeaviſen on the front page (in a fractur font to boot).
One of the senior Aperture team members went off to use the underlying OS RAW infrastructure in product called Gentleman Coders Nitro. It's a decent but little known Lightroom alternative with no subscription, albeit without all the recent Lightroom AI-infused features. It does have AI masking though.
I'm late to the party, but also wondering about Metal, and I have a question for you all. Do you happen to know how energy use relates to utilization? If I run a super duper duper fast thunder kitten kernel on an iphone (pending Metal, blah blah), would I expect it to also cost less battery? My naive guess is yes, but without logic to back it up.

It would be wild if some of these time-efficiency boosts you're getting with TK turned out to be energy-efficiency boosts too!
I have found that embeddings + LLM is very successful. I'm going to make the words up as to not yield my work publicly, but I had to classify something into 3 categories. I asked a simple llm to label it, it was 95% accurate. taking the min distance from the word embeddings to the mean category embeddings was about 96%. When I gave gave the LLM the embedding prediction, the LLM was 98% accurate.

There were issues an embedding model might not do well on where as the LLM could handle. for example: These were camel case words, like WoodPecker, AquafinaBottle, and WoodStock (I changed the words to not reveal private data).
WoodPecker and WoodStock would end up with close embedding values because the word Wood dominated the embedding values, but these were supposed to go into 2 different categories.

Frames of Reality: The Interplay of Causality and Temporal Perception
With Thunderbolt 5 it should be fairly reasonable to use an external GPU for more power.
When the videos are completely unrelated to your search, but just happen to be new/popular videos, then yes it's useless. Surfacing relevant videos would make sense.

For example, searching for climbing comp videos and getting a completely unrelated video about some new tech gadget released within the last couple days from a random popular content creators makes no sense.

Clearly, it works for Google (content creators intentionally make click-baity thumbnails and titles because Google encourages it), but it's user hostile: it's designed to suck you into a vortex, which is not what the user was intending in the first place.

That said, all content platforms do this right now, so my intention isn't singling out Google. It's frustrating nonetheless.
The logic is flimsy - having the newer equipment also means looking for reasons to use it to justify the cost so these dentists will often recommend expensive onlays instead of fillings for example.
We provide retrieval metrics for a variety of datasets and languages: https://blog.voyageai.com/2024/09/18/voyage-3/. I also personally encourage folks to either test on their own data or to find an open source dataset that closely resembles the documents they are trying to search (we provide a ton of free tokens for the evaluating our models).
> FCP was outstanding in its time, but was neglected.

I'm more of a casual when it comes to Final Cut Pro rather than a daily driver, but it does seem like the last year or two they've started to get back into the fight again. Some of the 360 VR/AI/multi-iOS camera changes seem to go more hand-in-hand with "Apple gives a shit about content creation again", buttressed by Apple Vision Pro and spatial photography.

As someone who's still eagerly awaiting like... any reasonable prosumer device to shoot for Apple Vision Pro, I think all of this industry is going to really ramp up in the next few short years very quickly. Gonna be interesting.

The 14" MBP has a 72 watt-hour battery and the 16" has a 100 watt-hour battery.

At full tilt an M3 Max will consume 50 to 75 watts, meaning you get 1 to 2 hours of runtime at best, if you use the thing full tilt.

That's the thing I find funny about the Apple Silicon MBP craze, sure they are efficient but if you use the thing as a workstation, battery life is still not good enough to really use unplugged.

Most claiming insane battery life are using the thing effectively as an information appliance or a media machine. At this game the PC laptops might not be as efficient but the runtime is not THAT different provided the same battery capacity.
I don't work in the maritime industry so I might easily be wrong, but my understanding is that these rules are generally enforced not via national laws directly but via insurance. You can build any kind of ship you like, but then you have these classification societies that verify whether a ship has been built to standards, and if not they won't certify it and you'll have a very hard time getting insurance for your vessel. And in the end national laws tend to say things like your ship needs to be insured etc., not directly how it must be constructed.
Yes, for some specific problems, raytracing definitely makes a lot of sense, but rasterization and 'geometry compression' via triangles also makes a lot of sense for other situations. I think the best approach will always be a hybrid approach instead of a 100% pure raytracing pipeline.

The other question is how much of the raytracing features in 3D APIs need to be implemented in fixed-function hardware units, or whether this is just another area where the pendulum will swing back and forth between hardware and software (running on the GPU of course).

But then maybe in 10 years we'll have 'signed distance field units' in GPUs and nobody talks about raytracing anymore ;)
You are all kinds of wrong. Geniuses (>165IQ) are rare enough that you can feasibly put in the effort to study them individually and in detail. Most people are unlikely to have ever met a single one in person. It would be ridiculous to try to source general stats of geniuses from people you have met in person.

Again you're not understanding conditional probability, the code I've been impressed by has a strong selection criteria bias as I'm only impressed by a very very tiny percentage of code that I've read, additionally I don't read every line of code written. This selection criteria is so strong that the fact that men in total write more code than women is almost completely irrelevant.

A large part of science is dedicated to not finding obvious things out about IQ which is increasingly hard to do as statistical tooling and data has become widespread. Most academics are stuck with old data and tooling and a existential requirement to find only politically correct results. If you think DEI is bad then you should see the anti-racists pledges that must be made by academics for access to data. My findings are from a mountain of data and sophisticated tooling but unfortunately I can't make appeals to authority when posting anonymously.
Pure speculation: This is about visionOS. Photo editing is the least friction "pro" task to bring to a spatial computing platform.

The other options I considered:

⁃ Renewed interesting in pro use cases in general. I don't see enough incentive for this. Apple's historical interest in this was winning over creatives, but particularly creatives interested in photography are already won.

⁃ Apple wanted the tech for something on iOS. I don't think there's enough "special sauce" tech Pixelmator has to justify this. Pixelmator's tech is only valuable as a full package.

I've mentioned this before, but in the “Measure What Matters” book the author talks about investing in Google in early 1999, and the founders were indeed projecting billions of dollars in revenue, using ads. It was in their pitch deck.

Now, to which extent they REALLY wanted to do this, and REALLY impacted the day to day decision, I don't know. Neither if said pitch deck had other options.
Prop 65 threshold for level of harm is two orders of magnitude below any effect level (not the harm level, effect) which I’d argue creates so many false notices of harm that most people simply ignore them eroding trust in the government.

Indeed the level is so low that under the law, the daily recommended dose of vitamin A for pregnant women would need a notice saying it caused birth defects. They had to ignore the law and add a caveat for vitamin A since not taking it causes birth defects.

If they didn’t pick an arbitrary threshold, ignoring scientific consensus on what dose makes the poison, it would have been far more successful.

I wish more companies had this perspective, in contrast to the "Barely MVP and mostly marketing spend" to get the most signups / MAU in hopes of an acquisition.
I will say that I did have a bad experience with one where the support staff was all family of the owner, because the receptionist mom was a miserable person and the hygenist wife was rough with the cleanings.

The one I'm at now is great, it's a solo female dentist and all of the support staff are relatively young women, they don't advertise as being specifically all women, I think it's just how it works out since most hygienists are women traditionally. But the younger hygienists definitely have a softer touch doing the cleanings and are better at giving information and tips while doing so. Has made me realize the hygienist at my old office was just unnecessarily rough and terse for no reason during cleanings.

Dentists rushing with the anesthetic is my biggest pet peeve with them. They always try to blame you in that you're special and need extra. I know there is some element of that, but it's mostly rushing
Congrats, that's an awesome average! I wish I was that fast. I don't time myself often, but when I do, I usually end up somewhere around 15 seconds. My efficiency is not bad, but my hands are just too slow.

I agree about beginner tutorials. There are some decent Roux tutorials, but they are mostly not targeting complete beginners. I believe it should be possible to make a Roux-based beginner method that is even simpler than the popular layer-by-layer beginner methods most new cubers learn. If you think about it, it seems almost obvious. If efficiency is not a concern, the first two blocks of Roux have to be simpler than the first two layers of a layer-by-layer approach, since you are solving a subset of the first two layers. CMLL is also obviously simpler than the CFOP last layer. The only thing that remains is the last six edges, and that's simple enough that I think beginners could figure out by trial and error. With the right simplifications (at the expense of efficiency) and good pedagogy, I therefore think Roux is ideally suited for teaching to complete beginners. Unfortunately, nobody has done it yet.

Some are good but then think about it this way, most of them look forward to leveraging debt. Which easily puts them in a position, (with for ex. the current high interest rate environment), in which they are trapped.

And ^ above we're just talking about the ones that seek long-term investment. The ones that look for a quick flip in 6-10 years? Hard to trust them
Yeah, I looked into lit as a possible way to do this, but was left feeling like then I had 3 things to juggle - lit, angular, and blazor. Should possibly revisit, though.
Geekbench 5 and earlier constructed the multi-core test as essentially running N independent copies of the single-core test. This effectively pretends that every subtest is embarrassingly parallel. Geekbench 6 switched to having the multi-core test actually operate like real multi-threaded software: a fixed-size problem is broken up to be divided among available cores, with a non-zero amount of coordination between threads and potential for less than perfectly linear scaling because Amdahl's Law isn't being ignored.
It was not. Maybe measured in relative terms the middle class is shrinking due to income inequality, but in absolute terms I am fairly confident it is at worst stagnating in America and western Europe. In many parts of the rest of the world there has been an amazing growth of a middle class that didn't exist before in the last decades. Eastern europe and asia of course.
I used to live in Taiwan. 80,000 NTD is about 2500 USD, so most likely that's a monthly salary. Pretty good salary if you live outside of Taipei, and doable within the city.

Ink is great for CLI tools and enables really great tools. People who are saying React only belongs on DOM are missing out- React is the world's most popular and powerful declarative programming paradigm. It's being used for native apps, VR, 3d, CAD and electronics.

React allows you to mix declarative and imperative programming concepts together in an effective way. To give a sense of why this is important: Imagine a CLI built with XML. It'd probably be pretty verbose and have a lot of domain-specific configuration. There also wouldn't be a great typechecker. React combines the most robust type-system in the world (Typescript) with declarative style. It has issues, but being "built for DOM/web" is not one of them.

RE: Ink. A simple example of where it is better than most tools is you can simply import a re-usable "ranger-style" file browsing component, and adapt it for things like exploring a database, a spreadsheet, or an API spec. The potential is very high. Hats off to the author and contributors!!
I should've spelled it out, but I used politician for a couple reasons. One of the reasons is that whether a reasonable person would think that was actually true is no longer relevant.

Look at the batpoop behavior of some very prominent politicians -- you can't distinguish that from parody. And look at the level of critical thinking we're seeing, with huge numbers of people believing things we think a reasonable person would consider improbable or seek confirmation.

In this environment, I assert that the defense of "a reasonable person would realize this is parody" is no longer true.
Honestly, the parent is pretty accurate. No one is claiming that P = NP. However, the technology to solved mixed integer programs has improved dramatically over the last 30 years and that improvement in performance has outpaced computational speed by multiple orders of magnitude. It's the algorithms.

I just went to pull up some numbers. The following comes from a talk that Bob Bixby gave at ISMP in 2012. He is the original author of CPLEX and one of the current owners of Gurobi. Between 1991 and 2007, CPLEX achieved a 29530x speedup in their solvers. Their 1997/98 breakthrough year attributes the following speedups, Cutting planes: 33.3x, presolve: 7.7x, variable selection: 2.7x, node presolve 1.3x, heuristics: 1.1x, dive probing 1.1x. I don't have a paper reference for these numbers and I don't think he has published them, but I was at the talk.

The point is that integer programming solvers perform unreasonably well. There is theory as to why. Yes, there is still a lot of searching. However, search in-and-of-itself is not sufficient to solve the problems that we regularly solve now. Further, that increase in performance is not just heuristics.
I think Pixelmator probably already runs on visionOS (I don't have one personally) but I doubt they spend enough engineering resources to make it amazing because the ROI isn't worth it for a third party company. But of course Apple can make Pixelmator amazing on visionOS without even noticing the cost.
They don't discuss this at all on their blog other than "Training Claude to count pixels accurately was critical." My speculation on how they accomplished it is either explicit tokenizer support with spacial encoding similar to how single-digit tokenization improves math abilities or an extensive pretraining like Molmo.

Sorry, no good references off hand. I’ve had to help write & generate public docs in DocBook in the past. But no expert on either editors, nlp, or embeddings besides hacking around some tools for my own note taking. My assumption is youll want to use your existing markup structure, if you have it. Or naively split on paragraphs with a tool like spacy. Or get real fancy and use dynamic ranges; something like an accumulation window that aggregates adjacent sentences based on individual similarity, break on total size or dissimilarity, and then treat that aggregate as the range to “chunk.”
>I'd get a professional teeth cleaning every 3 months if my insurance covered

Same, especially if I could get just a cleaning and not deal with the exam. I've often thought it'd be nice to be able to just pop in and get them professionally cleaned without the whole dental appointment around the cleaning.
Like how subroutines are implemented as Functions.

And by Functions you don't mean functions, but rather the letters fn?

That is certainly an interesting way to communicate.
That sometimes problems don't hurt until they're serious problems?
