> > But you can't say anything meaningful about space and time using only maths. It makes no sense.

> Why do you think that? I am talking about entirely abstract mental conceptions. I am not saying anything about how real physical processes work.

When considering if something is "real", maths and physics are OTOH deeply related (physics desribes the world using maths) and OTOH fundamentally different.

Maths builds systems of logical deduction based on self-evident axioms. "Pure Logic", ideally, if you will. The point is if the deduction is sound and how far logic can take you regarding abstract structure.

The simplest example is indeed the natural numbers, defined by the unit 1 and the rule that every natural number has a successor.

Physics, like other sciences, uses maths as a tool, for example statistics.

Physics is special in a way, because it applies stricter rules to what is a sounds and falsifiable theory.

But the basics are the same in every scientific discipline excluding Maths and/or Philosophy: a theory is only worth considering if it allows itself to be proven wrong. And the benefits of a theory or a theoretical model of physical reality lie in "predictions". A theory that does not make any prediction is not science, it's not a theory either. It's non-falsifiable; at best called metaphysics or religion.
Yeah that is weird. Because usually a "十" would mark the ten-count anyway, so saying a single digit could only be the ones-count, but they interpret it then differently to mean 80, even if you do not say "十". To me this is not logical and is unintuitive.
Good TWS headphones are better than the vast majority of wired headphones.

For example, Sony's headphones have lossless Bluetooth, and so do Samsung's, and the quality of the headphones themselves is quite good, even by audiophile standards, for in-ears.

You can also get bluetooth adapters for traditional IEMs, Fiio and KZ sell good ones.

At the end of the day, there really is no technical reason why bluetooth headphones have to sound any worse than wired headphones.
I haven't tried this software, but I imagine it's more about having the UI keep up, so you can stay in the flow state.

There definitely is one [1], albeit perhaps not as large and active as the homebrew communities for 8/16 bit consoles (which benefit from low-code tools such as GB Studio and the ability to sell physical game cartridges that do not require modchips) or more modern ones (which tend to have a much lower barrier to entry, given the better specs and availability of SDL ports and whatnot). It is definitely growing though, as I'm seeing more and more people get interested in developing for the PS1.

Can I ask, how are people affording to play around with GPT4? Are you all doing it at work? Or is there some way I am unaware of to keep the costs down enough to play around with it for experimenting? It's so expensive!
Really great job. Whether it’s legal for customers to share this info or not is really a gray area.

If the data is only shared in an aggregate fashion, I doubt they can do much without a subpoena. And then what? Sue the website? Sorry, no. Section 230.

John Doe suits against anonymous customers?

Nothing requires PriceLevel to retain the PII of users… they can capture the data, validate, and flush the PII. “Sorry, we have no information about the contributor of this data.”

My sense is this will be the primary innovation of this service— how to get this info and keep it useful to end users without very much ability to vet it. Worth the effort.
Always-on location tracking isn't about finding your lost devices - it's about the tracking data. The "feature" is just the hook to trick us into adopting it.
In your setup the applicant is asked to build a proxy, and that proxy should scale horizontally just fine. When you get to C10M you start thinking about unikernel-style or user-land networking stack style solutions, but that's not going to be a weekend project, and the conversation will get interesting. If you really expect a weekend project here then the answer to scaling the proxy is bound to be: horizontally (meaning: not that interesting).
Perhaps it also filters out candidates who want to rewrite everything in rust.
Today's GPU clusters is tomorrow's cell phone. But this codec doesn't require that much power anyway. I didn't try it but on some forum somebody claimed 0.5x speed on a Core(TM) i3-7100U CPU @ 2.40GHz [1]. It sounds plausible that with some more optimization and a bit better hardware, that's a bit more specialized for AI, it could do real time encoding and decoding on cell phones.

There are a bunch of Small Modular Reactor companies (Nuscale is probably the most well known in the media but venerable Westinghouse has one too). Elon Musk might be the world's foremost genius at handling government-related businesses (i.e. identifying where a startup can unblock government leaders who want things done but can't use existing orgs - electric / space) and he's stayed away from nuclear. I suspect a SpaceX analogue cannot be built in this field.

Part of why renewables are beating SMR companies is incrementality. You can build and expand power projects and scale up from small installations up high.

It's surprisingly hard to find economical places to build this in the US. Even geothermal in completely uninhabitable places gets met with opposition from groups like the Burning Man guys. I'm sure we'll conquer these regulatory things within the next half century, but until then we're in trouble and insistent on walking the precipice.
Dolt supports git like semantics, so you can commit, pull, merge, etc...
Weird take. We know communal lynchings happened; people literally took family photos by them! People happily documented that hangings were the town spectacles when they happened! Let’s not play rose tinted glasses about communities before social media: if you were not “in” that group you were vulnerable to violence or death. We have that now, where a disproportionate number of homeless minors are homeless because their parents kicked them out for being gay or trans and, clearly, no one else in their “community” was willing to take them in.

We need to be comparing how communities are right now vs how social media is right now and not some idealized notion of what in-the-flesh communities might be like. Right now we have a dearth of welcoming in-the-flesh community alternatives for people that have been cast out of traditional social groups and use technology to cope. This doesn’t mean technology bad. It means society needs to change so technology isn’t so tempting.

I recommend the movie "Walk the Line" for folks on the fence. Entertaining and might learn a thing or two.
Let's try an example: `average page views in the last 1, 7, 30, 60, 180 days`

You need these values accurate as of ~500k timestamps for 10k different page ids, with significant skew for some page ids.

So you have a "left" table with 500k rows, each with a page id and timestamp. Then you have a `page_views` table with many millions/billions/whatever rows that need to be aggregated.

Sure, you could do this with backfill with SQL and fancy window functions. But let's just look at what you would need to do to actually make this work, assuming you wanted it to be serving online with realtime updates (from a page_views kafka topic that is the source of the page views table):

For online serving:
1. Decompose the batch computation to SUM and COUNT and seed the values in your KV store
2. Write the streaming job that does realtime updates to your SUMs/COUNTs.
3. Have an API for fetching and finalizing the AVERAGE value.

For Backfilling:
1. Write your verbose query with windowed aggregations (I encourage you to actually try it).
2. Often you also want a daily front-fill job for scheduled retraining. Now you're also thinking about how to reuse previous values. Maybe you reuse your decomposed SUMs/COUNTs above, but if so you're now orchestrating these pipelines.

For making sure you didn't mess it up:
1. Compare logs of fetched features to backfilled values to make sure that they're temporally consistent.

For sharing:
1. Let's say other ML practitioners are also playing around with this feature, but with a different timelines (i.e. different timestamps). Are they redoing all of the computation? Or are you orchestrating caching and reusing partial windows?

So you can do all that, or you can write a few lines of python in Chronon.

Now let's say you want to add a window. Or say you want to change it so it's aggregated by `user_id` rather than `page_id`. Or say you want to add other aggregations other than AVERAGE. You can redo all of that again, or change a few lines of Python.
That's pretty funny. ISTM that now that you have HN commentary you're thinking a bit more expressly about what you're really trying to achieve with this interview question.

I have a theory some big cloud provider moved a ton of racks from SXM2 P100's to SXM2 V100's (those were a thing) and thus orphaned an absolute ton of P100's without their baseboards.

Or, these salvage operations just stripped racks and kept the small stuff and e-waste the racks because they think it's the more efficient use of their storage space and would be easier to sell, without thinking correctly.

> we hope this actually leads to a faster sales cycle because buyers have pre-qualified themselves.

But by obfuscating their pricing they are able to create a marketing "lead" when you contact them that will one day evolve into a client and therefor its better for them to "pre-qualify" you.

I personally hate this model as it drives me absolutely insane to spend a month of going back and forth with a vendor, going over what i'd like to do and why, investing time in understanding their stack and product, only to find out its 2x my budget or something like they wont even consider me since its less than 10k. If you hide your pricing, make me go through an extensive process, and I let you know im trying to implement a PoC or a small entry level and you come at me with $1k/month I'm likely going to walk away and be frustrated enough to not want to do business with you ever. You've created more of a negative experience that i will tell others about than a "lead". Yet this goes against every companies thinking (even my won) so it must work on someone.
I would argue that both vertical AND horizontal scaling are required, because the winning solution in the end at the absolute highest level of this question, is one that gets the work done for significantly less $$$ than my golang implementation, in whatever language, stack, cloud or bare metal you deem appropriate.

Deleting the tests will not impact coverage as the tests at the integration points will necessarily already cover any local functions. That is unless said local functions are unused, but in that case you would remove the unused local functions anyway, still not impacting coverage.

But you are right that deleting the tests isn't an option as it will break the contract that was entered into with the users of the code. Of course, you can't modify the tests for the same reason, so...

> an alarming email on her phone. After 55 years, Small Press Distribution (SPD)—one of the last remaining independent book distributors in the US—was shutting down immediately, with no advance notice or transitional support. Its website went dark, its Twitter account was deleted, and no one was answering calls.

Why not give warning of imminent shutdown?

> To make matters worse, many small presses say SPD owes them money. “We’re owed upwards of $8,000,” says Gzemski. “We just released three books [at Noemi], and all of the preorder and event order revenue from those books has disappeared. [...] Goettel says SPD owes Black Lawrence Press more than $17,000—an enormous sum for a small press.*

Was the reason for no warning that they needed or wanted the incoming revenue, which they might not have gotten if they'd given a warning?
If I'm understanding this correctly, the problem here is other saw companies aren't implementing a safety feature because SawStop has a patent on the relevant technology. Now the US federal government wants to make that safety feature a requirement and SawStop pinky swears to release the patent.

Why don't they just strike down SawStop's patent on the technology instead? Bosch apparently already tried to implement the tech but was scared away by SawStop's lawyers. There's a proven interest in the tech from other industry players. Is there any evidence that the proposed regulation is even necessary?

Seems ridiculous to me that they'd even allow a company to prevent other companies from implementing safety features in the first place.

I’m paying about $50 service fees for the two blades currently out for repair. The 10” replacements cost over $200, and the 8” dado would require buying a new stack… around $250. The same folks who sharpen and true my blades do the repairs. They’re local to me here in Maine.

Ruminating a bit:

Cheaper blades are replaced more often with use and can’t generally be sharpened; SawStop tech doesn’t change the lifetime of a blade unless an activation happens. So, if you’re already willing to run to the box store for another blade semi-regularly, whether one survives activation perhaps isn’t material?

On the other hand, somebody who doesn’t regularly use their saw is probably both more price conscious and less likely to need sharpening/replacement often. I assume they care most about whether an activation forces them to buy a new blade (and a $100 brake). I suspect those are the people who propagate “SawStop = trashed blade”. For them, it’s true.

Between 1984 and 1989, the homicide rate for Black males aged 14 to 17 more than doubled, and the homicide rate for Black males aged 18 to 24 increased nearly as much. During this period, the Black community also experienced a 20–100% increase in fetal death rates, low birth-weight babies, weapons arrests, and the number of children in foster care.

It becomes valuable if it either compensates for the lack of hyperparam tuning in all or a broad class of models, or the result is precisely presented to say something like "better than random if the model is a linear svm with C=1".

Right now we are somewhere in between where the results are presented to seem somewhat generally useful, but when you tweak the hyperparams you realize that the utility is potentially quite narrow.

We either need broad utility or increased rigor in reporting - we cannot abandon both.

Yeah that's an interesting paper [1], and label imbalance is a case we have not investigated (we were able to reproduce some results from it - the DAL experiments in Section A.3 "Reproducibility Experiments" in [2] come from there).
