Maybe I'm missing what's interesting about this, but a function like f(z) = 5z + 2 would output a wave with changed amplitude and phase when z = sin(x). That doesn't seem that interesting to me, so f(z) must have some other interesting properties?
Are you sure they didn’t make the deal?
My personal experience. I've been in the industry for over twenty years and never worked in a place where drug use was normalized. Most of the workplaces had a drinking culture to some degree: beers in the office fridge, regular happy hours, corporate events where you got hammered with your coworkers. Over time, marijuana use has become more normalized, a condition that I believe more reflects society than tech.

One of my old coworkers was on meth for a while. She didn't really talk about it, though.
What does it mean to be overstaffed? I think that's a real question on which we can build.

I define a skeleton crew as roughly 10% of the organization. If you cannot run your basic organization with just maintenance and basic bug fixes on 10% of your team, you have too much complexity in your system and you need to work to reduce your maintenance burden. If you need less than 10%, you have an well-architected system, or you have a very small system.

Everything else in the system is research and development. These are new features that will drive revenue, or reduce non-engineering support costs, or otherwise drive new capabilities of the business. In that sense, every successful business is over-provisioned because they are all working on business bets for more revenue.

So yes, every company can be leaner, but it will be at the expense of growth. Now, there are more subtitles in the article to address within that context. For example, it is also true that managers will keep an underperformer for longer so long as there is a net positive because they may be struggling to hire otherwise, or they may be bracing against future layoffs. (A lean, effective organization in an org that otherwise has game theory about layoffs knows that you keep people around that you're not afraid to lose. It's a terrible way to run an organization but it happens.)

It is also true that we have work to do to level up the engineering management profession, as mentioned by the article.

However, when discussing this, the key driver of employment growth is the pursuit of revenue growth and I think that's the primary lens and disconnect here.
How many seconds do you reckon it takes to pass a cyclist if you are capable of going from 20mph to 40mph in about 4 seconds? Swerving and gunning it hardly seems necessary if you have any visibilty whatsoever.

> By vastly underpaying, the clients of those buying goods transported by these vehicles are vastly underpaying for these externalities.

> 3) Exclusive pedestrians/bicyclists, who are highly dependent on large delivery vehicles to take goods from point of manufacture to places they can access via walking/biking, are vastly underpaying for these externalities.

Are you honestly trying to say that all, or the majority of, HGVs on the road are exclusively delivering items for pedestrians and cyclists? Or that if you drive a car, your local supermarket no longer needs HGVs for delivery? Or that moving those goods in hundreds of private cars is more efficient than moving them in a single HGV?
Show HN: Cito – Actionable data observability for data teams
Hi HN! We’re Clemens and Felix from Cito - thrilled to show you what we’ve built to help data engineers stay on top of data quality issues. Think Datadog meets Incident.io.

Tests in dbt are great when checking whether specific expectations are true, but don’t work well for use cases where data patterns may change over time. When relying on testing alone, data teams regularly face situations where business stakeholders identify data issues in dashboards first, eroding trust. In such situations, understanding the implications of an issue and debugging can be a very manual and time-consuming process.

To help data engineers ensure trust in data, Cito makes it easy to go beyond simple tests. By executing scheduled or near real-time out-of-the-box anomaly detection tests (row count, schema change, etc.) or custom SQL tests, data anomalies are detected and communicated in the context of the relevant column-level lineage via Slack.

We believe data observability solutions should not stop at alerting teams to anomalies and our ambition is to support the complete end-to-end workflow of data engineers. Leveraging column-level lineage, our solution makes it straightforward to understand the context of anomalies. In addition, by automatically providing transparency in a git-blame-like fashion around ownership of data models and showing who made changes most recently, Cito helps to accelerate internal communications when troubleshooting.

We’re super keen to hear your thoughts, ideas and experiences! You can also use our docs to try Cito in less than 15 min.
You need clients that will allow you to be that for them. Sometimes they just want a really expensive code monkey.

I’m not exactly sure why. Maybe paying hundreds of dollars an hour is a sort of status symbol?
> FTX agreed to buy Voyager

Wait, was that ever finalized?
Binance was threatening to dump a huge amount of FTT tokens on the market. FTX has a big+vulnerable position in FTT. FTX asked Binance to sell them the tokens for a fixed price, so as not to crash the FTT token price. Binance declined - this was yesterday/today. Of course the price of FTT crashed today. And now Binance buys FTX to help them out... smells like Binance played 4D chess all along.

I didn't go to Sunny's trial, but it didn't seem to generate much drama.

The idea that he was the manipulator is a "finding of fact" in legal parlance. She can't raise that on appeal. Maybe if the defense tried and the judge refused to allow it, that could be appealed as an "error" and thus appealed. Offhand I don't think that happened in her trial, but I could be wrong (?)

Only a new trial could bring that up. An appellate court could order a new trial; that happens sometimes.

And, of course, in the sentencing hearing, they can try to blame Sunny. I don't think that reduces her sentence to zero, if it works at all.

IANAL, so someone who is: feel free to correct me.
Open Source Antidote: critical and alternative views on FOSS
I just started working with Lambda, so my experience may just be the teething pains, but. I find the developer experience a bit jarring. My lambda is in python, but every time I want to test my code I have to "build" the lambda with the `sam build` tool and only then can I exercise it. It takes a non-trivial amount of time to build.

The deployment story looks good though, with the `sam deploy`, but for now I can't get over the developer experience.
That's the exact opposite of what a good manager would do. They'd take the blame for things that go wrong and credit the team for everything good that was accomplished. They'd be an advocate for their team and their reports individually. I've been fortunate to work with a few of those managers and they've been the ones that have been really successful long term. Keep searching or take the management route yourself and show them. It's very rewarding!
How many votes can Gurgaon's urban population bring? Not as much as Kisan Sabhas in Sohna, Pataudi, Farrukhnagar, and Manesar. How many votes can urban NOIDA or Ghaziabad voters bring to UP Legislative elections? Almost nothing compared to farmers outside of either. Activism is strong in India - the kind of person who lives in a Housing Society in Noida, Gurgaon, or Ghaziabad doesn't know or care to partake in Gheraos, Bandhs, or Dharns to push their point through.
> what the alternative must have been

It's clear it would have involved everyone losing their money and Bankman Fried being on the run à la Do Kwon.
Argh, that resonates. My general strategy: speak up briefly on how we should do {x}, and then, when I am not heard, do their thing {y}, which usually fails, since if I speak up in the first place it means I probably know what I'm talking about.

Anyway, they can recognize the failure of {y}. Now it's time to make my suggestion again, not in an asshole way, but rather: "I think we should do {x}" as if it's the first time I said it; or "Let's revisit what you're trying to accomplish here."

The happy story would be that people are abashed at my great wisdom and sorrowful that they did not heed it. More accurate story is that no acknowledgement of anything occurs, but they are more receptive in the moment, and even a bit more receptive in the future. Took a long time to arrive at this, sadly, my great wisdom notwithstanding.
This is impossible to answer and a seemingly constantly moving target. The truth of the premise relies upon a bunch of assumptions, including that other people are staffing the aid agencies, manning the ships that send supplies, directly providing aid in the field wherever it is needed, founding, running, and investing in companies that can pay you a high salary. That specific strategy might work perfectly well for the average marginal person searching the Internet from the US to figure out what they should do, but it can't be universalized, because if everyone tried to do it, the entire system would collapse on itself.

Just do whatever good you can do. If you're in a position where a high-paying job in the west is something you're likely to slip into anyway and none of the other roles you'd be relying on seem appealing or likely, then sure, donate some of that high salary. But we can't possibly recommend unqualified that everyone should do that.
Remember this is a NON-BINDING letter of intent. I wouldn't be surprised at all if this doesn't actually happen and just a bunch of ballyhoo. Unlike Twitter, FTX won't be able to drag CZ down to Delaware’s Chancery Court to force him to acquire it.

I don't know to what extent that is true, I'm not saying it's not, but I also wonder. Having been in a lot of places where the traffic is unpredictable, I've noticed that people pay a lot more attention to the road and their surroundings and in general drive more defensively than on places where there is an assumption that everyone is following the same rules. This is just anecdotal of course, but I think it would be interesting to look into. I certainly feel a lot safer as a pedestrian in Mexico than in the US for example, even though the traffic is more unpredictable. But again it might be an illusion.

That's not true at all. PhysX comes with a CPU solver by default, and using the GPU version comes with significant restrictions in customising the behaviour. Unreal Engine games (when they used to use PhysX) were all CPU based, for example.

Anyone using either of those is cross-compiling (hence my comment specifying "on an Amiga")

It's unlikely to find many people running GCC on AmigaOS itself so it makes sense to deprecate the support for it
Snoop Dog loves her - she did her time and did not snitch :).
There are a couple of other comments that have mentioned oscillation modes, vibrations, etc. The first 7 pages of this series on sound synthesis might help give an idea of where these might come from:

https://drive.google.com/file/d/12SM0SAOvMq166gc8B1b81Y_S7HP...

The third page in particular shows a plot of "amplitude" versus "frequency" to show the "harmonic spectrum of a sawtooth wave". The "frequencies" correspond to the modes of vibration (i.e., sine waves of different frequency), which are the "eigenvectors" in this case. The "amplitudes" are the relative contribution of those vibrations to the overall sound, and these correspond to "eigenvalues".

The article is talking purely about constructing sounds via synthesis, so there's not necessarily a linear system associated with it, but there is a connection. Wave equations represented by linear partial differential equations can often be analyzed as a linear system that has these "modes of vibration" (i.e., series of orthogonal sinusoids at different frequencies). If you were to, for example, model a plucked string (like a guitar), you can model the solution as a weighted sum of eigenvectors (in this case, "modes of vibration" or sinusoids of different frequencies). The "weights" would be the eigenvalues, which determine the spectrum and ultimately the timbre of the sound produced.

That might seem more involved, because it's an infinite-dimensional linear system (i.e., the vectors are functions on a interval, rather than finite lists of numbers). It turns out, though, that the finite-dimensional discretization of an infinite-dimensional linear system (i.e., a partial-differential equation approximated by a finite-dimensional linear system) will sometimes have eigenvectors / eigenvalues that have similar features as the infinite-dimensional case. For example, there are certain finite-difference operators that can be written in matrix form whose eigenvectors will work out to be sampled sinusoids.

I'm not totally sure of the history, but I think a lot of the interest in eigenvectors / eigenvalues as a topic in matrix theory originated from this are (i.e., numerical solutions for partial-differential equations that were used to model physical systems).
Feels odd to gender this suggestion. I find myself doing this as well.
Wasn't there a post hitting the HN front page just yesterday or two days ago about how FTX was close to being illiquid, and most of the top comments were about how wrong that analysis was?

I can confirm this. It’s also nice to see a new paper on this. I’ve been using this knowledge professionally for the last 24 years as a front of house engineer.

Anecdotal story time:
You’ve may have seen this video, or some variation of or maybe even the TED talk inspired by it…

https://youtube.com/watch?v=GA8z7f7a2Pk

…what few people know and most don’t because I have not shared this publicly (in media at least) is that I was mixing this show.
We we’re on in the middle of the day and a few bands had been on before us. By this point in my career I had already been to the gorge several times and the hill has always been a problem. On this particular day during the already frantic pace of a festival changeover with no sound check, the system tech is talking up the new delay stacks they beefed up for this year. This was great news and were geeking out and he’s showing me where they’re at on the console which is of course buried under some convoluted series of navigation and button presses to get to, given the atrocious UI design of digital electronics. Now generally given these circumstances, convention holds that the delays are set to some arbitrary value and the guest engineer generally need not concern themselves as the system techs will be monitoring them. To my horror were getting to the dancy part of our short set and I’m doing my due diligence and looking back at the hill and wondering whats up, why isn’t anyone dancing!?! The delays were not turned up! None of the previous engineers that day had thought about them and the techs while excited had set them to some arbitrarily safe low level. So for me this video marks the moment I checked the delays that day and turned up the bass. So if I may add to the TED talk; if you want to start a movement, turn up the bass.

This effect is literally everyday at work for me and why I have a job.
That’s nice, that just means US road planners don’t know how to build safe cycle tracks, and US drivers aren’t very good.

Thankfully I live in a more civilised country.

I also see you’ve taken no real effort to educate yourself. I assume you’re going to continue finding way to blame cyclists for road issues, rather than consider that the issue is more complex than cyclists = bad?

A far easier to digest primer on eigenvalues is available from 3Blue1Brown [+]. His presentation format is undeniably approachable, so much so that I think you could probably use it to teach linear algebra and eigenvectors to 9-year olds.

A few times I have wished for a way to grow maps, but generally to shrink maps I don't think there's any big advantage to a built-in rather than your own function making a new one. (It would only cover the case where you know you want to shrink but don't know if you need to shrink because you don't know how many elements you removed or overestimated by, which I think is pretty unusual.)
To be completely frank, it worked too (at least on me). If you asked me two weeks ago which company would go bankrupt first between FTX and Coinbase, I would be hard pressed to answer, even though we all have access to the financial documents of Coinbase and all we have from FTX is SBF glamor and hot air.
Another part of the puzzle is telling people to wash their hands has been a mainstream message for decades. It wasn't asking people do to something new and uncomfortable.

The great schism wasn't that great at the time. There were multiple schism before it and after it. And contemporary historians didn’t really see it as some permanent irreconcilable split between the eastern and western Church. They hardly even mentioned it.

It’s a bit like the fall of the Western Roman empire. Seems like a huge event for us but people living at the time hardly noticed it. The Latin and Greek/Orthodox churches were drifting apart for centuries prior to the “schism” and continued doing so afterwards but its significance wasn’t that clear at the time.

At the beginning of the first Crusade the Emperor was still seen as the universal/supreme ruler of the Christian world (at least in theory) and recognized as such both by the church and most European monarchs.

> And in any case, the Byzantine doesn't seem to have nearly the impact of the Renaissance or other Western inventions of the second millennium, even before the Great Schism, or at any point in its existence. For better or worse

That’s debatable. I agree that relatively little innovation occurred but most ancient knowledge was primary preserved in Byzantium. It’s possibly that the Renaissance would not have occurred had the Roman empire fallen during the dark ages. Arguably it began in the Byzantine empire during the 12 and 13th centuries and just shifted to Italy in the later centuries. Italy was socially, economically and culturally interlinked with the empire and Italian humanism is pretty clearly inspired by Byzantine humanism which preceded it.

> of the Fourth Crusade in 1204, when the West damn near killed that culture

True. But the west wasn’t exactly homogenous either. Besides religious matters there was no clear boundary between Byzantium and the Latin world. Arguably most of Italy had more in common with the Empire than with the Germans. Venice was basically an offshoot of the Byzantine world. It was closer to the empire socially and culturally than to any place outside of the Italian peninsula. Of course to most French and German crusaders it seemed like a fairly alien place, but they probably feel similarly in Venice or Naples.
I find pretty often when people resolve conversations like this by saying 'do your own research', particularly when the research to be done requires any homework at all, it is shorthand for 'find a loud voice saying things that are compatible with the worldview you've decided on already'.
> Are the apps I'm working on good use cases?

It's OK... it would work.

It could be somewhat more expensive or less expensive to host, and somewhat more or less performant. (You didn't say where the data lives, but if it's in a database and you aren't doing something extra with it, then this layer might not be that important, one way or the other.)

For a 100-user app, I'm guessing the major cost here is the switchover cost. Whether it makes sense or not depends on details of where you are now and what problem(s) this is meant to solve.

No one here knows that (maybe even you don't either?) so we can't really give you an answer, just some general pros and cons of serverless.
> This is my point. If you can see several 500lb people a day going about your everyday errands around town

Compared to how many people you see total going about your everyday errands? Tens? Hundreds? Thousands? That is my point: you're deliberately ignoring the overwhelmingly vast majority of the people you encounter in favor of a very tiny minority solely for the sake of asserting that tiny minority to be far more common than they actually are.

> And how often are such massive people on TV shows that aren't specifically about 500lb people? Almost never.

Exactly. Shows have to go way out of their way to find 500lb people, because they are exceedingly rare. If they were anywhere near as common as you assert, then they would be far more prevalent on American TV.

In attempting to refute my point you've accidentally proven it, twice in the same comment. I rest my case.
I mean, that could still happen. I am not ready to give up hope yet.

Ask HN: Adobe robbed me, what do I do?
I'm pretty salty, I've been paying for Adobe Stock for about $40/month and you get about 10 assets a month. I had 240 assets, so spent about $960 to get it. They failed to charge my credit card and now they removed all credits and said they cannot give it back.

My credit card is on file and is working fine for all other products. I basically feel robbed. It just seems silly that they cannot give the assets back. The manager told me the same thing and told me to look at the Terms of Service.

Is this my fault given they had the credit card on file and its working fine for everything else? It just seems like Adobe has zero accountability.

Also I guess a bit of a warning to anyone who has Adobe Stock, make sure your payments are being processed or they will remove years of credits... To buy the amount of credits I have on their site, it's like $3000.
