> I tried it a while ago (more than 1yr ago) and was taken aback by the number of AWS constructs it uses. I wasn't sure what all it was creating on the backend and what the impact of those constructs on the product's recurring billing would be.

This is common for AWS sales demos. In this case there are cost externalities, but I'm more used to caring about authn/authz externalities, where the flashy demo makes you think "it's so easy" but then you get into the nitty-gritty of making sure that whatever thing is safe to deploy in a production environment.

You have to dive very deep into AWS docs and forum posts (hopefully, but less likely if it's a newer AWS product) to find all the ways to limit access to the thing and especially by the thing, especially since so many AWS demos come with IAM policies that are littered with asterisks.
I have been using it for over 5 years for all personal things like email, banking, and paying bills. Once you find good hardware for the OS, it runs very well, but you either need a lot of memory or to close each VM as soon as you're done with it and run only one-two VMs at a time. I would say minimum of 16 GB RAM with 32-64 GB preferred.
This. VSCode has so many great features. Adding in keybindings for vim via a plugin has worked great for me.
How did it change your life? Did you take a supplement containing it, or was it some experimental treatment?

Yep! 1080p is unfortunately now unbearable to me for monitors and laptops, although thankfully I have not reached the point yet where I'm this picky about phone screens
That might be true, as a matter of legal interpretation. If so, that's a solid argument for updating the traffic law with more precise language, but not much else.
I want to like System76, but ultimately can't. Dell, Lenovo and others have much better hardware and still run Linux just as well.

I don't think they were thinking about reusable rocket engines at that point in time. The primary (?) advantage of methane over kerosene is that it doesn't deposit soot on engine parts, which is highly important for SpaceX today, but not really anyone else in history.

Here's one reference to methane-LOX in the book ("nobody could see any point"):

- "The VfR was completely unaware of all of this when they started work. Oberth had originally wanted to use methane as fuel, but as it was hard to come by in Berlin, their first work was with gasoline and oxygen. Johannes Winkler, however, picked up the idea, and working independently of the VfR, was able to fire a liquid oxygen-liquid methane motor before the end of 1930. This work led nowhere in particular, since, as methane has a performance only slightly superior to that of gasoline, and is much harder to handle, nobody could see any point to following it up." (pages 7-8)

There's more references to methane + [exotic oxidizers], because (going off my memory) they were to trying to min-max Isp performance, for interplanetary probes, constrained to a certain cryogenic temperature range. (This predates radioisotope heaters, I believe. Not *electric* generators -- these little heater things [0]). Liquid CH₄ looked like a good match for the deep-space thermal environment.

[0] https://en.wikipedia.org/wiki/Radioisotope_heater_unit

- "Deep space probes, working at low temperatures, will probably use methane, ethane, and diborane for fuels, although propane is a possibility. The oxidizers will be OF₂, and possibly ONF₃ and NO₂F, while perchloryl fluoride, ClO₃F, would be useful as far out as Jupiter." (page 191)

(If anyone at Google is reading this, could you consider adding search support for numerals in the superscripts and subscripts block [1]; they don't seem to be normalized in a sensible way. ClO₃F and ClO3F are entirely different searches).

Thanks for sharing!

Quick question: How did organizing data in this format help you?
I had the opposite experience. My teacher took extra care to explain to us why and how certain things worked in math. The reason I loved math so much, and still do, is because I never had to memorize anything. I just had to understand how it worked. In biology, however, it was very different. I had to memorize facts instead of understanding them.
There are two types of people - those who perform better working in person, and those who perform better working remotely. Forcing either to work in the other fashion is harmful. The best solution for productivity will be that which respects both types of people.
Awesome product. How much $$$?
This is the natural result of state standardized education. It has its pros though, like getting a functionally literate and numerate workforce of average people when done decently. It will rarely serve people of the author's level of intelligence. That's one of the cons.
The two questions I really remember from my neuroscience grad program are:

"You discover a mouse that can sense radiation. How does it do it?"

"You are riding a bicycle. Explain."

We had to do it in 2 pages, NSF grant rules on spacing and margins.
That's my choice too. It is clean and easy to read. Additionally, I found that when I share my screen on Zoom, students can easily read my code when I am using SF Mono.

> > people tossing specific seeds on the ground 20,000 years ago

> This seems irrelevant to whether farming occurred before people.

It gets to if for example squirrels storing seeds underground is possibly farming or not. It's an intentional activity, but takes too long for a specific squirrel to see much benefit from it. IMO, it’s kind of a mind bender when you really dig into it.

I think a reassemble argument is squirrels as a species farm though individuals don’t.
There's also the success story of terror victim Karen Northshield. She has had about 70 operations after the march 2016 Brussels airport attack.

Any report about 'detecting' something without mentioning safe levels or how amazingly sensitive some types of detection are should be taken with a huge grain of salt.

> There was a degree of central organization since the project leader, Linus Torvalds, approved kernel changes and set the philosophical tone, but Linux probably could have survived the removal of its leader. It was decentralized enough to have no single point of failure.

I submit that Torvalds' genius could be subdivided into technical heft vs. laissez faire management.

He made the in-vs-out calls more or less optimally, and leveraged the "libertaian" feel of the GPL, without getting bogged down by FSF ideology.

It was a small target to hit. The pattern might be less difficult to replicate now, but would a Theo de Raadt be able to carry the torch?

Torvalds nailed the timing/location problem.
I've been curious for a while why someone hasn't extended markdown into LaTeX territory and this looks like someone did.
Meh. Footguns are underrated. Let’s return to the Wild West of the 90s.

I’m only partially joking. But this was one case where they probably thought it was a good idea, turned out to be a bad idea, then couldn’t turn it off without breaking a bunch of code.

I think most people don't understand how difficult it is to wield power over others when you're aiming for a good community. Many commenters who complain about any form of governance don't realize what a small fraction of power is actually used, and how much more oppressive their ideas would be in practice.
>No arguments about the legal protections of bodily autonomy,

It's not about your body autonomy, it's about taking the life of an unborn child, who clearly does not not belong to your body as he has a different DNA.

If you want body autonomy, you can pull a tooth or cut a finger.
I’ve been working to improve this very issue myself; the compulsion to seek further options before committing to a decision has diminishing returns.

How do you get a business idea?
I've always wanted to start my own tech-related business. If I woke up tomorrow for an idea for SAAS business, I generally know how to bring it to fruition. I've literally wanted to do this for decades. My problem is, I can't think of something that I can build that someone else would want to pay for. I'm not concerned about getting rich. If I could clear $2000-$5000 a month, that would be great.

So, my question is, for those of you who have done it, how did you get an idea for a SAAS kind of thing, or even indie software or some sort of product?

However, just as open source developers don't owe downstream, package repositories don't owe open source developers. The package repository isn't preventing the developers from continuing to publish their packages elsewhere

If I'm an open source developer who starts uploading malicious packages to a repository they aren't obliged to not delist my malicious packages. PyPI is proactively considering critical packages without 2FA protection malicious
The "ergo stand" photo actually had me fooled for a while--the "ghosts" just show you different ways the one giant monitor could be positioned.

A 2x(16:9) configuration where the monitors could be brought really close together would be neat though...
So doctors know less about a situation than the patient experiencing the pain?

A good coach has zero impact on their players that actually experience the game?
In particular, if package indexes start introducing additional requirements for developers, as mentioned in the article, then I do worry that it could risk moving an unreasonable level of burden onto developers (who may initiate or develop code purely for their own enjoyment).

Currently the "critical package" categorization may offset most of the likelihood of that occurring, although I'd expect there could be problems for some projects even so.

I wonder whether PyPi considered making 2FA-at-publish-time optional and instead offering a question of 2FA-at-package-install-time.

In other words: "pip install --2fa-signed-packages-only" or similar.

It's possible they didn't, or weren't able to, because the ecosystem is already widely deployed and many package version upgrades (including transitive dependencies) occur automatically.

Roughly speaking: I like the author's suggestion (quoted below) of making the the software package ecosystem an immutable (content-addressed?) space, where policies and attestation about whether to use those packages is opt-in based on rules-based overlays. That'd be ambitious but technically feasible, I think.

"So if I were to wish for something, then that the index has no policies beyond immutability of assets, and instead we use an independent layer of the index to enforce policies."
Is there a way to download this graph?
This is a really interesting field of discussion, because there are such strong arguments in both directions. I don't think there's a single right answer here.

I personally come down more on the side of "registries should have policies limiting the damage that their participants can cause", but I absolutely respect the arguments that "volunteers working for free should not have additional restrictions placed on how they do their work".

UK: pretty sure you dont get charged for anything execpt possibly ambulance/hospital if you are not from UK or EU, but I suspect it’s so unusual most NHS staff wouldn’t know how to bill you.

>> if: - job hopping hurts long term career growth at management level and above

Sounds like you're a team lead/manager looking to move higher up into management in the future? If that's the case, pay is certainly important, all else being equal you take the higher paying job because typically in the higher paying job more is expected of you, but you need to look at how the new role is going to get you the experience that gets you into whatever management position you're hoping to grow into.

The wild card of course is the economy, in a recession it becomes a game of musical chairs. If things get bad you might end up back on the market real quick. Maybe the hiring managers today would compromise and hire someone with only short tenure positions because there aren't any other levers they can tweak and they either hire or lose the position. In a recession the hiring manager doesn't compromise, you do. Maybe we go into a recession, maybe one has already started, maybe it's all a false alarm.

> Its just one of those goals that people setup to distract themselves from the boredom of current problems

I think it has many benefits, chief among them will be the innovation in tech and engineering we will derive from it, in addition to a much needed perspective change: it seems that Life is rare and that treating our Home planet with reverence will be a priority if the species is to survive.

I think the resources and drive to get us to Mar is enough to make all of those things happen, what I don't think will occur without an immense level of investment is to have a sustainable colony not dependent on Earth or space-based manufacturing for some time.

It's hard to see how, in our current path, we do not end up just squandering all of the progress we have made these last ~300k years as a Species and succumb to extinction because we refused to learn the hard lesson that Humanity seems to only thrive when it is faced with an immense, often existential endeavor; I wish we could just be so enlightened as to get along as Humans and solve all the Earth based problems, but it seems that only under extreme duress are we able to make any impact on these immense problems. And so far, at least in my Lifetime, I don't think anything but Mars colonization has the potential to make any of that happen.

It isn't so much distraction, as it is to re-imagine what our destiny and what Life could be.
Wife is a internal doctor (Switzerland's biggest hospital), and we were very wary about avoiding giving any kind of antibiotics before our kids reached age of 1. Common knowledge among peer doctors is that even single usage before 12 months significantly increases risk of diabetes later in life significantly (and god knows what other nasty side effects).

In some cases they are miracle cure, with some nasty side effects. But general over-prescription even in relatively developed world is ridiculous.

From my less developed and highly corrupt home (Slovakia/Czech republic), I often get news from friends who got prescribed full course of antibiotics on clearly viral infections. General doctors there are mostly on such an abysmal level that self-treatment is sometimes better than their clueless visits. Even for small kids.

Another item are painkillers - I see prescriptions for literally anything, usually heavy doses of paracetamol or ibuprofen but I've seen worse for maladies which don't warrant it. I don't even take those in pharmacies unless I know I have acute inflammation to treat.
> a finding scientists have called “disturbing” and “concerning”.

What were they expecting; that stuff sprayed onto crops will magically not end up in people?
Well when your kid is screaming in pain from an ear infection, I'm not sure I'm going to decline to treat them with antibiotics because of some small future risk of Crohn's disease.
> Replace “alcohol” with “alcohol from fermented fruit”

That’s different, someone can be aware of fruit but not the alcohol within it. To assume they are interchangeable is it to make assumptions about what’s going on.

Consciousness is a product of the physical world. That's the theory and explanation.
That's for the rack.
Are there any techniques for recovery you discovered?
Having done a lot of biology, I'd disagree that we understand biology.

My background is neuro, so take that into account. But in neuro, we've nearly no idea about the larger parts of how it all works. Sure, yeah, electrically active neurons, we have that down. But the non electrically active parts? I mean, we're still debating about how much of the brain is glia. Like, we can't even agree on how to count. Don't get me started on synapses.
From what I gather, it’s extremely beefy, physical servers with DPUs built-in. I.e. perfect for large on-premise deployments while maintaining the high performance that DPUs enable, all as a single appliance.

It’s the kind of thing I would expect Nvidia or Dell to become big at as well, and Bryan Cantrill has enough leverage to pique my interest significantly here.
You can always tell the people who have had jobs where they learned how to run a cash register versus the ones who haven't.

I love self checkout. If there's no line at either the cashier or the self checkout, I'll take the self checkout every time. It's way faster, I don't have to make chit chat, and I don't get cashiers trying to upsell me or ask me for donations or whatever else.

Way better experience for me. I don't care if I'm saving the company money by doing the labor for them. It's still a better experience for me so who cares.
The US did not give rights to Blacks, etc. The US recognized those rights. This is the genius of the Declaration of Independence. This is exceptional.

The criticism that the Constitution didn't go all the way in the first go is a bit unreasonable. People forget how far it did go. For example, it rejected the notion of a nobility class. It explicitly rejected establishment of a state religion. We forget how exceptional this was at the time, we just take it for granted.
It’s partially doctors giving in to the demands of patients who want a prescription for everything. I think it’s a side effect of our expensive healthcare system. People don’t like paying their copay for just a band aid. Or to be told “it’s a virus, get some sleep and drink fluids”. They want to feel like they got something for their money.

Yes! The stand is really great; I have mine on an adjustable height desk and it takes up so little space. Which is perfect as I have so little space to work with. I got it recently and for me it's spot on as my main monitor. The built-in two device kvm saves me so much time. I can't speak to the resolution woes as I was using two very, very old monitors at home so I've just been basking in the glow of using something made recently. I've been enjoying the vertical space for tasks like going through logs/giant spreadsheets and then switching to the dual monitor mode for the usual multi-tasking. I've used dual 32in curved fancy monitors at the office before and found that I would just use a fourth of the real estate available. My brain prefers the vertical space over the horizontal.
Not really for infrastructure though? Still neat.

I do have to wonder though, you're saying 'Screen scaling with Mac OS' and 'scaling issues on mac' but this is just a monitor, Isn't that "MacOS screen scaling does not work well" and "mac scaling issues" rather than any defect with the device itself?

If I got paid by Big Olive as a lobbyist I'd at least take a swig. (I believe that lobbyist made a claim about drinking a spoonful.)

Then I'd probably cough and pivot to how to tell the difference between high quality olive oil and what the fraudsters are pushing. I'd celebrate the good work of my good friends at the California Olive Oil Council and many others to address the growing problem of fake olive oils. Let's protect our small olive farmers!

In short: if I instead turned red, started freaking out and stormed out of the interview, it would probably be wise to stay away from olive oil until you figured out exactly what happened there.
