Companies are like swarming fish. They perceive a threat and they all dodge together. Whether there’s a major recession, a minor, or nothing, they will lay off and freeze hiring across the board. I would suggest you find a way to hang in there but start looking immediately, and keep looking. Eventually you’ll find what you want but it’ll be an extended and disheartening search and you might not make as much as you would have a year ago. But over a lifetime career it’ll average out and you’ll be fine. Just remember, as with all things, this too shall pass.

What you do need to do from now on though is always have a plan for what’s next and an exit, even if you’re happy where you are. You never have to exercise your options, but optionality alone has value and it’ll provide a level of continuous confidence and courage. It also provides a focus for your development. Good luck.

I had a friend interview at "Big Nameless Corp" a few years ago. He said when he saw that the engineers interviewing him all had Windows laptops, he knew immediately it wasn't an engineer-friendly culture. I always thought that was funny.
As someone who works in healthcare, so much of what I read about AI makes me think that the people who are enthusiastic about healthcare AI don't have much experience doing it.

The scenarios rarely seem to fit with what I'm actually practicing. Most of medicine is boring, it is largely routine, and if we don't know what's going on, it's because we're not the right person to be managing the patient. Most of my time is spent talking to people - patients, colleagues, family. I explain the diagnosis, I talk about the plan, I am getting ideas of what the patient wants and values, and then actioning it. I spend very little of my time like Dr House pondering what the next most important test to perform is for a patient who is confounding us.

> Across all AWS availability zones instances are mispriced by roughly $400/hr at any given time. This means that, with just a single instance of each type, Amazon is missing out on $200/hr or roughy $1.7 million each year. This is over roughly 15,000 pools of instances. Given Amazon controls roughly 100 million IPs, we can guess that each instance pool probably has on the order of 1000 instances (more for smaller instances, less for larger instances). Given this, the average mispriced pool might have hundreds of instances, meaning hundreds of millions each year in missed revenue due to mispriced spot instances. Because amazon keeps their number of instances a secret, it’s difficult to make a precise estimate from the outside, but the missed revenue probably falls somewhere in this range.

You are hypothesizing that the price differences produce "lost" revenues.

An alternative hypothesis can be that the price differences produce similar or higher level of revenues for AWS through price segmentation, with Amazon recognizing the lack of adoption of certain spot instance bidding features and auction markets reacting appropriately.

Unless you have the capacity and quantity demanded for each instance types, you can't prove your hypothesis. You are assuming scenario 3 (below) with no insights into price elasticity of the underlying customers.

Example:

Baseline:

Instance types A and B are equivalent.

A is priced at $3, with capacity of 1000, quantity demanded of 800.
B is priced at $2, with capacity of 1000, quantity demanded of 200.
Total quantity demanded = 1,000.

Revenues from instance type A = $3 x 800 = $2,400
Revenues from instance type B = $2 x 200 = $ 400

Total revenues = $2,800

Scenario 1: All customers purchase instance B instead due to better price discovery.

Revenues from instance type A = $3 x 0 = $0
Revenues from instance type B = $2 x 1,000 = $ $2,000
Total quantity demanded = 1,000.

Total revenues = $2,000

Amazon loses $800 in revenues, there are no "lost" revenues" recovered.

Scenario 2: Amazon changes instance type B price to $3. Total quantity demand decreases to 900 due to price elasticity of instance type B customers.

Revenues from instance type A = $3 x 800 = $2,400
Revenues from instance type B = $3 x 100 = $300

Total revenues = $2,700

Amazon loses $100 in revenues, there are no "lost" revenues recovered.

Scenario 3: Amazon changes instance type B price to $3. Total quantity demand remains at 1,000.

Revenues from instance type A = $3 x 800 = $2,400
Revenues from instance type B = $3 x 200 = $600

Total revenues = $3,000

Amazon recovers $200 in "lost" revenues.
Ask HN: Adding database constraints for writes only?
So, this is all just a hypothetical I'm thinking about, but I'm really curious what people think about this. Let's start with an example:

Let's say we have a schema with a `users` table, with an `email` column. For whatever reason, our users don't _need_ to supply an email (maybe they can optionally provide a phone number instead), so the column is _nullable_.

But a few months down the line, we decide that all users must provide an email. So we want to change the schema so the database enforces that all users provide an email. But we can't. Because we already have a bunch of users who didn't provide an email! So we have lots of rows where `email` is null.

One solution here would be to turn all the nulls into empty strings, for the migration. This works for a time (though you now need to adjust your code everywhere to handle empty strings as `null`).

But then the business decides to switch back to allowing users to not provide a username. This leaves us with two options:
1. Fill the `email` column with an empty string, whenever it is not provided.
2. Fill the `email` column with `null` whenever it is not provided.

The second option is obviously pretty bad, because now we need to handle both nulls, and empty strings. So we'll use the first option.

All in all, not _so_ terrible, right?

---
But this is actually a special case where it works out okay, because an empty string is obviously an invalid email address, so we can treat the empty string as special. But what if we need to consider an empty string as a value, and can't use it as a null replacement? Or what if the column is a numeric type - 0 is not always a great number for the absence of a value.

The "problem" here is that database constraints apply to a whole table, including existing data, when we really want to impose a rule on writes, I'm not aware of a way to impose these types of constraints only on write, but not on read.

I imagine one approach would be to "archive" the existing table when adding constraints, create a new table with the new schema (where writes will go), and have all reads go through a view that `union`s all versions of the table. I have no idea how this could work with foreign keys though, or how this would affect performance.

Of course, another option is just to do this logic at the application level, but I like the idea of the database being able to enforce all the business rules (at least in theory, I've never tried that in practice).

I have very little knowledge of quantum physics, but in my mind there is some similarity between quantum phenomena and backward raytracing in computer graphics.

In forward raytracing, images are rendered by "shooting" photons from all lightsources and seeing which ones end up hitting the player's camera. This is similar to what we think happens in nature, but the calculation is extremely inefficient, because the vast majority of photons never hit the player's viewpoint.

In backward raytracing, we only shoot "photons" backwards from the player's camera, and see which rays end up hitting a light source. This computation is much more efficient.

It makes me wonder if our "simulation" uses a similar shortcut

> not every artist has the financial ability to do that

Yes. I went to see a band maybe six to eight years ago. The lead singer asked the crowd to buy some merchandise a few times, and went on to explain that since the shift to streaming happened, they don't make nearly as much from radio play and album sales, so depend on touring income much more than they used to.

At least dynamic pricing gets money to the artist that would have just gone to the scalper before. Ticketmaster also has a "Verified Fan" feature where you can request tickets (https://blog.ticketmaster.com/verifiedfan-faq/), with the goal of preventing bots from buying them in the first few seconds when they are made available. While tickets can be sold/transferred for Verified Fan events, I'm not sure if there's an option to prevent sales over face value.
I recently published a paper, where we explain how an FDA approved prediction model, build into a widely used cardiac monitor was developed with an incredibly biased method.

https://doi.org/10.1097/ALN.0000000000004320

Basically, the training and validation data was engineered so an important range for one of the predictor variables was only present in one of the outcomes, making perfect prediction possible for these cases.

I summarize the paper in this Twitter thread: https://twitter.com/JohsEnevoldsen/status/156164115389992960...

Like complaints about the GDPR, these types of blog posts are always worded like the law is the issue instead of the people who exploit it.

It's not like these laws are without issue or room for abuse, in truth most laws are like this, but a lot of the time people don't know the law and don't care to put in the minimum effort to apply it.

So we get people clamoring for free-market solutions which have demonstrably failed to address these issues for decades and end up leaving behind all those people which accessibility laws were made for.
I think it's worth mentioning that price is only one way to allocate the scarce resource. What strikes me as better socially and for the liveliness of the audience is to offer discounts to the top 25% of fans, as determined by Spotify or Apple Music, and then let the free market fill in the rest. Some balance of this would let regular fans get a shot while also maximizing revenue for the other block of tickets.

Bluetooth is massively more complicated than WiFi. It has a whole service enumeration/discovery layer baked in that IMHO tried to cram way too much into the spec. Whats even more amazing is that some of the hardware vendors at the table during the development went "F that" and added some side channel audio stuff that bypassing most of the stack.

But mostly the problem is that too much of this complexity fell on hardware vendors and they suck at writing software. There are umpteen bajillion different bluetooth stacks out there and they're all buggy in new and exciting ways. Interoperability testing is hugely neglected by most vendors. The times where Bluetooth works well are typically where the same vendor controls both ends of the link, like Airpods on an iPhone.

In 2020 I tried buying some reputable brand Bluetooth headphones for my kids so they could do home-schooling without disturbing each other. It was a total failure. Every time their computer went to sleep the bluetooth stack would become out of sync and attempts to reconnect would result in just "error connecting" messages, requiring you to fully delete the bluetooth device on the Windows side and redo the entire discovery/association/connection from scratch. The bluetooth stack on Windows would crash halfway through the association process about half of the time forcing you to reboot the computer to start over. Absolutely unusable. I tried the same headphones on a Linux host and they worked slightly better, but were still prone to getting out of sync and requiring a full "forget this device" and add it again cycle every few days for no apparent reason.
> which theories are highly speculative.

So QM itself is on very, very solid ground. You're using it now on your computer.

The interpretations of QM and the attempts to reconcile the exceptionally well tested mathematics of QM and the reality that we experience which is not-QM at all are all philosophical with zero evidence. Everyone just tries to make compelling arguments based on things like Occam's razor about why their horse is the best one in the race without actually knowing anything at all.

We have place a few bounds around things like Bell's inequality so we know that local hidden variable theories are ruled out, but that is about it.

The title article is very interesting because its one of the first few actual tests to probe if there really is a transition between QM reality and classical reality. Regardless of who actually wins the horse-race the important thing here is that there's slow progress being made on trying to experimentally test theories. This is why I've always liked the Penrose models of collapse better than the MWI models since the former have some chance of being actually testable, while with MWI you just blindly decide it is true or not and then you argue a bunch about philosophy and never do any experiments, which isn't science. Penrose models of collapse might be wrong but at least they're in principle testable, which is incredibly exciting about this article.

I think a bigger isn't isn't just collecting consent for this, but it's questioning is the data neccessary to perform the business need they're asking for it and is it coerced consent.

GDPR is great, however phone companies still collect biometic data and claim that it's "necessary" (It's not) They do so and claim it's neccessary, when it's the copy of the passport that is necessary. Additionally forcing the collection of it otherwise you can't get a phone number is not exactly consent. That's coerced.

This is the case of Telefonica in Spain (Where I went to the store and they didn't warn me but coerced me into going through this with a store rep right there) This is also the case in Sounder apartments where they want pictures of your id and of you to rent from them. https://www.sonder.com/
> Memristor and analogue processors to accelerate ML are doing this. Neural networks are ok with operations on noisy, analogue states. Analogue operations such as op-amp multiplication are more power hungry than individual digital gates, but some are less power hungry than digital multipliers which use thousands of gates.

I checked Mouser just now and memristors are not in stock: https://www.mouser.com/c/?q=memristor

If we are talking about imaginary components, then I think quantistors will change everything.
That scenario sounds like it lends itself more to AI automation than a Dr. House type one.
It baffles me that people can watch the trendline of

"Job X can be automated in 40 years" (5 years ago)

"Job X can be automated in 10 years" (2 years ago)

"Job X can be automated in 5 years" (1 week ago)

And feel comfortable poking holes in the AI models, pointing out where it fails. Obviously? But nobody 3 years ago thought that graphic design or creative writing was on death's row either.

You have to spend a modicum of effort looking at how predictions have evolved over the past couple years, but once you do, it's very clear that mocking current AI systems makes you look like a clown.
Not surprising. With oil and gas tight, the substitute (coal) is laying around everywhere a- plentiful and cheap - and much, much worse for the environment.

They irony is that the US investing heavily in it's own oil and gas discovery for the last decade means it's one of the few countries not backsliding on climate.

single unit landlord here… i’ve done the management myself, and i currently use a management firm (which charges me a very reasonable percentage each month).

i made the shift because i was tired of having to deal with every minor crisis myself, take time away from work to (for example) meet prospective tenants, get a new AC installed, handle the make-ready process, etc. i had a good long stretch with one tenant that was low-maintenance but they moved out suddenly with very little notice (add managing the lease agreement to the list of stuff i don’t like doing as a landlord) and a lot of work i had to do to clean up after them.

all things considered, i’m happy to fork over 5% each month to someone else to deal with those headaches.
Is that the town-assessed value? This [1] shows 2.708% so on $1.2M that would be $32k in taxes, I think something is special about your situation?

There is also a newer workaround by styling the input element it self by using appearance: none. You can do some clever stuff with the :checked selector, multiple backgrounds, clip-paths, masks, etc.
Not clear at all and addressed by the parameters of the thought experiment. Remember that Mary has near omnipotent knowledge of light and vision.

Yeah, I keep wondering about this business model choice too. Netflix is the only major streamer left at this point charging for HD and 4K as separate tiers. The other major streamers do sometimes tier on simultaneous screens, and often refer to higher tiers as "family plans".

Netflix is at least unintentionally messaging at this point that "only families want or need higher quality streams" and that is a very weird mixed message in the current streaming market, especially now with their slowly increasingly more hostile messaging that they are tired of people sharing passwords (because the shareholders demand account growth in a saturated market with a much-increased field of competitors).
I did not work there, but I had a copy of this iconic June 1997 issue of Wired Magazine and managed to lose it somehow:

> Lately some weird new copy and paste bar appears, no idea how I’m triggering it.

iOS 13 added a whole set of gestures that all key off of three-fingered interactions with the screen. Just tapping with three fingers shows that bar, which is probably all you're managing to do accidentally.

The rest: three-fingered pinch-closed to copy ("picking up"); three-fingered pinch-open to paste ("putting down"); three-finger swiping left/right for undo/redo... and three-finger double-tap for an undo shortcut.

Totally agree this is undiscoverable, but it's also fairly well gated behind a single root gesture so once you understand the trigger it's memorable.
I feel like a law that is open to exploitation is an issue it itself.
It's very clear that you really don't want to believe in the probability. You know nothing is 100%. If you assign 100% for no leak then your bias level is 100%. If you assign some probability then we just disagree on the probability level. Btw, people from the lab live there and shop there.
> these types of blog posts are always worded like the law is the issue instead of the people who exploit it.

The law is the issue. To say otherwise would be like saying that we didn't need to fix Log4shell and should have instead just tried to do something about the people who exploited it.
My humble opinion; AI is supposed to be the acronym for artificial intelligence, but marketing has usurped it to refer to machine learning, which is nothing more than a neo-language for defining statistical equations in a semi-automated way. An attempt to dispense with mathematicians to develop models.

What amount of energy is necessary for an event to be reflected in a statistic? You have a box of 2x2 meters with balls of data, and a string with a diameter of 1 meter with which to surround the highest concentration of balls possible, and those that remain outside, there they stay. Statistics and lack of precision are concepts that go hand in hand (someones say even it is not an science).
"No true Scotsman is not Scottish" seems true, definitionally. Same applies for aristocracy: they are the ones who are served by special interests, by definition.
