> Are the cameras similar to what's in a consumer digital camera, that is, a single image sensor behind a bayer filer and a lens?

Yes they're quite similar to consumer camera sensors, our sensors are usually from high quality production bins. We advertise this quality as "scientific CMOS" (sCMOS) to help highlight this.
Consumer sensors can have a significant number of sensor defects which can be corrected so they aren't noticeable in casual photographs, but these defects are very detrimental for scientific imaging where quality is paramount.
Another big difference is the noise and quantum efficiency characteristics of the sensor which is another key requirement for scientific instruments.

We don't supply lens', I think the logic is that scientific customer's know exactly what kind of optical setup they want so most customer's would tend to use their own optical equipment or buy it in.

Our camera's are monochrome (scientific cameras tend to care more about raw resolution than having a smaller res with bayer layer) so customers typically use different color/wavelength filters to get what they want and process them into true color images later if needed.

> Or does it use some other configuration, like an array of image sensors?

This particular camera, the Zyla has just one sensor. Though it is a little unique in our portfolio, in that the sensor can be read out from both halves simultaneously in various patterns. If your interested in the hardware we provide lots of info in our hardware manual: https://andor.oxinst.com/downloads/uploads/Zyla_hardware_use...
I don't think we offer multi-sensor solutions, though I could be wrong.

> And does sensor readout work similarly to a consumer camera, sequentially reading out rows of sensor data?

Yes, there are two electronic shuttering modes we offer: rolling and global. Rolling takes a sequential row by row readout, and global does a readout of the entire sensor. The camera's used by the observator can only do rolling, but we have other Zyla models which also do global. There can be tradeoffs in choosing which one to use, typically framerate, noise and image distortion are the key factors in choosing.
Global is available on some high end consumer cameras, but generally most consumer sensors will do rolling. Though this may have changed since I last looked.

> Is there any cool software processing during the capture, like decovolution?

In the camera side of the company, we try to leave the image as clean and raw as possible.
We perform correction processing during acquisition on the camera; as high quality as the bins are, you still have to correct and characterize for various things to get the best performance in a scientific scenario.

In the applications side of the company we do all kinds of image processing: deconvolution (this is a big deal in the confocal microscopy world, we have our own patented deconvolution method: srrf-stream) https://fusion-benchtop-software-guide.scrollhelp.site/fusio..., AI analysis, 3d/4d imaging (https://imaris.oxinst.com/). Probably lots more I don't know about (I'm on the camera side).
I still don't see what you are getting at. It is hard to generate good information about the risks and benefits of drugs and doing RTCs is very difficult, for the reasons to which you refer and others. Are you advocating that we just give up on knowing this stuff? That we do large RTCs that have the statistical power to characterize more "context"? I'm having trouble understanding whether your comment just comes down to "getting knowledge is hard and I'm tired of people trying to do it."
Why would you mention something while it was not relevant? The Weasley's dad was known to be intrigued by things of the Muggles, and was known to collect items such as the specific Ford (car not available in the US so the reference was a bit lost).

If Ron had told Harry about the car in some random conversation in a previous book, you would probably then complain about some bit of obtrusive foreshadowing ruining the plot line. Okay, maybe not you specifically, but that's another common trope of criticism of fiction.

I made this visualization of the zeta function in javascript, it is infinitely zoomable, and you can play around with parameters: https://amirhirsch.com/zeta/index.html

It might help you understand why the hypothesis is probably true. It renders the partial sums and traces the path of zeta.

In my rendering, I include all partial sums up to an automatically computed "N-critical" which is when the phase difference between two summands is less than pi (nyquist limit!), after which the behavior of the partial sums is monotonic. The clusters are like alias modes that go back and forth when the instantaneous frequency of the summands is between kpi and (k+1)pi, and the random walk section is where you only have one point per alias-mode. The green lines highlight a symmetry of the partial sums, where the clusters maintain symmetry with the random walk section, this symmetry is summarized pretty well in this paper: https://arxiv.org/pdf/1507.07631
>employees are the most expensive thing a SaaS business has.

I'm pretty sure for the overwhelming majority of (successful) SaaS businesses, the most expensive part is the marketing & advertising budget. 30-50% isn't uncommon, because the returns on successful sign-ups are enormous.

Not so. early stage funding goes to hiring.
In the context of a discussion on JS, the spec assigns a very specific meaning to the term “object”, one which value-types do not satisfy. That is, indeed, the entire point of this thread, and to suddenly switch terminology then ramble about how you’re better than “script kiddies” screams rhetorical incompetence.

It's clear that you don’t know JS. I was trying to help you understand one interesting design decision they make, but you’ve taken to personal attacks against the entire community in a way that I don’t find worth humoring. Good day.

You're exactly right. Many normal users are "single issue voters" when it comes to OS choice. Linux could be the best operating system in the world, and Windows could be flaming trash that will drain your bank account and shoot your puppy, but if the user has an application that's important to them that runs on Windows but not Linux, they will always choose the "shoot my puppy" choice because at the end of the day they just want to ruin that application.

What was the longest time between 2 commits to Postgres?
This is how I assume one of the ways an expert system would play out:

1. A system which understands not just the language but the meaning behind it and the cultural context around it.

2. Let's assume it's multi-model and have all the senses having the same level of technical maturity.

3. It has read all the text available for all the major sciences and understood the meaning behind it including the possible applications of it.

To that end, having the above conditions satisfied I am assuming there should be major breakthroughs in all sciences. So far what I have seen is that the AI system is able to selectively brute-force it's way in finding a solution. Maybe I am just being impatient.
> A culture without writing doesn’t produce a written record of its history

But... they can still draw it. And they did it a lot in the caves. We have careful pictures of recognizable species of animals, sculptures and strange pictograms that could depict particular concepts so they take the same role as words. We even have entire narratives about hunter campaigns drawn in the cave walls with a specific number of male humans, dogs and specific animals chased, and how they chased it. Even their personal objects were shown. In this sense, this is literature. Sort of. Is just that we can't read all the symbols and can't know if those symbols had a sound attached, but we can understand easily a lot of the history depicted.
Is there an actually convincing simple protocol for a 2D character buffer? (As opposed to a jumped-up typescript like the DEC terminals.) I’ve tried looking at the IBM tradition, and while it’s certainly different, I wouldn’t say it’s better on this particular point.

(There is also the part where a VT100-style display is a bit more than just a character buffer—there’s rewrapping on resize, for example, which IIUC be on for some lines and off for others—but let’s assume we’re willing to postpone updating window contents until the resize is concluded so can afford to do that on the application/VT100-processor side. Even though that feels like 1995.)

I read Pale Fire on the plane recently. Picked it up randomly, knew almost nothing about it. It is absolutely riotous. Most of the references probably went over my head, but I was immediately annoyed, then grinning about how annoyed I was, then tearing into the next page to try to unwrap just who the hell is Kinbote. About 10 pages in you will discover that you're never going to fully figure it out, and then the question is where the hell is this character going to take you. To the fractal depths of his soul, turns out.

> i'm used to not quitting one job until i have the next one lined up

Well, that certainly affects your flexibility with this sort of thing. Many years ago, I learned that this stance is too limiting for me and sometimes encouraged me to take jobs that I shouldn't have taken.

Everyone is different, of course, but what works for me is to keep enough of a bankroll on hand that I can go at least 6 months without an income (Although these days I keep 1-2 years worth). That gives me the breathing room to be pickier about where I work.
so, in other words, a 5% tax to the consumer.

> There are tons of people like me, and they're easy to find on Product Hunt and in r/SaaS

So with the help of ChatGPT, there will be even more people like this, all screaming into the void for attention but getting none because it's all too diluted.

I think building a job or business on top of ChatGPT is like building a retail business on Amazon. If you are successful, competitors will duplicate your offering and undercut your price, or Amazon itself will come out with their own version and promote it ahead of yours. OpenAI, Microsoft, and the other big AI companies will do the same thing. You don't think they have a priviliged inside view of what people are doing with these products?

If ChatGPT is the thing that makes your business idea viable, then it also makes it easier than ever for someone else to copy it.
That's a good observation - the UI is a very thin wrapper around the optimizer.

One fix would be changing the minimum number of chips per color under "advanced options > requirements" to 0.
You don't see yourself hiring help for:

* Keeping things up and running

* Building the systems that the AI interfaces with

* Supporting any large contracts

In my experience, one enterprise contract with specific requirements basically requires you to hire a dev to support them.
Floating bamboo houses keep this indigenous tribe safe in a typhoon
Yes, I (OP) came across the PDF first but sought out an alternative for readability from HN.
I meant the message bits carried by the emission, but you're right, the way things are done, more bits are prepared at first, to make the message more resilient against noise, and only then all the bits are modulated onto the EM emission. So while not all emitted bits do come correctly, all data bits can be reconstructed.

Which makes me wonder, whether this way of achieving resilience against changes along the way is necessary. Maybe the data bits can be modulated directly onto analog current, and error resilience can be achieved by remodulating it on the analog level. Then, the emission would have as many bits as there are in the message, error-resilience (modulating, demodulating) would be done strictly using analog electric circuits.
To be fair, MS has done an incredible amount of work to keep backwards compatibility. It may not 'show' to the end user, but they put in significant programming hours/effort $$$s for this. Now, this doesn't mean it was all for the 'end user' but they did benefit a bit from this.
And only once every four years.

Unfortunately, they award it on the 4n+2 years. As someone born on a 4n+0 year, I’ll have just 38 years, which is too severe a disadvantage for me to stomach, so I didn’t bother with it.

"The old doctrine was that CO2 was a proxy for air quality"

That's not accurate, though. CO2 is, on its own, an air quality concern.

It has also been known, or at least part of the conversation, since Florence Nightingale's time, that fresh air reduces infections (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9300299/). This research makes a small tweak to our understanding, but it's also something that's been suspected/suggested by others for decades.

This research isn't "challenging" anything, it's merely expanding our understanding of causation about previously observed correlations. It's good to know what's happening. It's silly to make it out to be something it's not.
I would love to see him write a book, or even just publish a nice compendium of his papers ala Donald Knuth's Collected Papers series (with light editing/updating, background info, commentary, etc.) I think that would truly be a pleasure to read.
The fact that you can't see where mask mandates went into effect isn't an indictment of masks — it's about the effectiveness of mandates. People were already wearing masks before the mandates, and people who were dead-set against masks continued not wearing them after the mandates were in effect.

Regarding doctors and nurses, they are trained in how to wear PPE and are much more likely to do so appropriately than civilians or (especially) children. PPE can be effective against COVID, but probably 1-5% of civilians wore masks according to protocols. Wearing a mask incorrectly might help, but AFAIK there are zero studies on this.

Definitely. Filtering particulates and tempering the outside air is the way to go in anything but most extreme situations. I suspect even designing a fallout shelter you would want to go that route.
I think the point is that building any kind of tool to enable this is surface area for an attack. The design choice is to remove any possibility of that happening at all.
What are your favorite "science" jokes?
I use ChatGPT pretty much every day (enough to where I could probably call myself a "prompt engineer" if I didn't think that that was kind of asinine), I'm pretty good with it, and the reason I did that was kind of for the reasons laid out in this blog post.

I've always been of the opinion of that for anything involving "at will employment", the name of the game is "adapt or die". Fundamentally corporations are sociopathic [1], and if they don't think that they're getting enough value from you, they will fire you and/or not hire you. It's decidedly not-personal, they just don't feel like you're contributing enough to give them a sufficient return on investment.

There are plenty of trends that I've thought were kind of dumb but I try and get at least minimally competent simply because I'm afraid that if I don't then a company will fire me and hire some kid straight out of school who is excited for this stuff. I learned basic Ethereum Solidity stuff, for example, even though I think cryptocurrency is pretty stupid, because I was afraid that that might end up being the trend, whether or not I agree with it. I learned Node.js very shortly after it got any traction (2012) because even though I hated JS at the time, I felt like there was a good chance that Node would catch on. I actually don't think that ChatGPT is stupid, I think it's generally useful, but I've become competent with using it for the same reasons.

I get a little annoyed that people act like they're entitled to have the same job for forever and won't be forced to adapt to the times. That would be great, but that's not going to fucking happen, and it's not new with AI. You've always been at risk of being replaced with new technology and automation, and that's not a bad thing.

[1] The people there aren't necessarily sociopathic, but businesses are a sort of separate thing that makes it much easier for these people to carry out sociopathic things.

leetcode doesn't catch bad hires, as someone whos done a lot of interviews, we could easily catch "bad" coders with a very simple whiteboard test or a "look at this code and tell me what you think"

but people being bad at code aren't the company killers, its the toxic people who are "good" at coding that do. They can be very good at these kind of tests, but are absolute shites to work with.

I think we actually agree more that I let on, and you are right that coding tests should only be a part of the interview process.
