Python's classes can change dynamically though during runtime. So each iteration of a loop would need to check if the shape has changed. I'm no Python expert though, so please correct me if I'm mistaken.

But it's more than that. There's a really nice talk here from the creator of the Flask framework about a bunch of different semantic choices in the language design, leak out into the ecosystem and make many optimizations impossible: https://www.youtube.com/watch?v=qCGofLIzX6g
I think it is not so exceptional, it is just this is one of the first ones we spotted.

Practically "outer solar system objects" and "interstellar objects" are overlapping categories since there is transport between the two.

The problem with an unofficial side load like this is that it can get around some of the built in protections of iOs that I actually like. It opens up attack vectors that Apple hasn't considered yet.

I feel like with official side loading, Apple would be inclined to lock down what apps can do without explicit permission, or better yet, require more explicit permissions when an app is side loaded. Like make every API call require permission the first time it's called.

I'm fine with it being difficult to side load, but I really want it to be official so that Apple at least considers those attack vectors (like they've been doing on MacOS).

What's the flash translation layer made of? Is the flash technology used for that more durable than the rest of the SSD itself? (like say MLC vs. QLC?)
Yes the microwave should have accessible firmware. All electronics should have accessible firmware, software and hardware. Because it prevents abuse of powers (like Epson printers, for example) and, most importantly, it prevents waste.

Apple, due to its war on repair, locked software and influence among its peers is an environmental catastrophe.
I think OSS is a hoax. We're incentivized to give away immeasurable amounts of our time and 99% of these people don't get back much (if anything). I've been producing OSS code for 3-4 years, and although I'm really happy that people are using the code I've written (and reading my tutorials) I can give you many-many examples of __very important__ OSS code, that's maintained by people for free in their free time and they get almost nothing back. I've stopped producing new stuff a year ago, and now all my extra time goes into endeavors that have the potential for profit. My problem is that many many big companies say that OSS is important, that OSS is a "good cause", etc, but the fact is that it is mostly free labor for "achievements", and green boxes on a webpage. It is smoke and mirrors.

I'd say it's worth it to the mid or long term, so you'd benefit from CL's strengths and advantages. It's more difficult than mainstream languages to start a web app only because there are less material, project templates or full blown frameworks to get started, so you better know the web already. In addition to the awesome-cl list of libraries, I recommend to check out the Cookbook https://lispcookbook.github.io/cl-cookbook/web.html to grok the different parts of a lisp (web) app.

That’s good to hear. Hopefully this trend continues and we break the 20 year vehicle ownership age. There’s too much waste in this country and the amount of materials, energy, and water to manufacture a new vehicle is way too high.

Maybe we will get to a point where vehicle lifespans can outlast a typical human as we transition to EVs which have less moving parts and lubricants than ICEs.
Meanwhile the hactivists have almost freed ARM's proprietary gpu from the shackles it's been kept in & are close to having phones that can (when bootloaders can be unlocked) run regular Linux OSes. Pinephone is pioneering how to control cellular modems. We are so close to having pocket sized computers that can run a choice of operating systems.

The timing here, of phones that might run the existing, well supported, well documented open source driver, is a happy coincidence. Hopefully we see devices emerge with unlocked bootloaders that permit some evolution.

The solution is easy. Don't apply to jobs that involve stupid leetcode hoops.
I use on Linux the XCompose key (which is assigned the menu key right from the space bar, or the "Print Screen" key), and then "\mu" like in LaTeX. I don't need to think about it because I have used LaTeX for years.
I also use the XCompose to generate € and ß which are special symbols in my native language. This has the advantage that I can use the UK International layout for everything, which makes specifically writing code much more comfortable. Also, the xcompose keymap is just a text file in my home directory, I can extend it at any time and take it with me. The method is also independent from any application.

Also, Emacs has an input method which supports "\mu", and this convention is also used in Racket for things like λ.

As a physicist who does a lot of mathematical programming for my every day job, I'm going to disagree pretty hard.
I don’t think the argumentation in this article is that strong. Replace 64 by 32 and 128 by 64, and you could have said it about the 32-bit to 64-bit transition. That transition _did_ happen, though.

I think a better argument is to look at history. Looking at https://en.wikipedia.org/wiki/X86, 16-bit x86 appeared in 1978, 32-bit in 1985, and 64 bit in 2003.

So, we have 7 years from “8 bits isn’t enough” to “16 bits isn’t enough, and 18 from there to “32 bits isn’t enough.”

I see something similar to (and probably a consequence of it) Moore’s law there: “we ‘need’ one more bit of address space every year or so”.

If that holds and Moore’s law continues, I expect we’ll run out of 64-bit address spaces about 32 years after we ran out of 32-bits, so around 2035. Top-end machines also should have use for 50-bit address spaces by now.

There were 64 TB systems six years ago (http://highscalability.com/blog/2015/8/5/how-do-you-program-...). That’s 46 bits, so I think my prediction is in the right ballpark.

Yes, modern V8 does this, as does the JVM. Common Lisp runtimes also often support this, though I think they usually leave it up to the programmer to choose when to compile a function, they don't always do it automatically. The .NET CLR also behaves like Julia - JIT compile on first execution of every function.

If Emacs doesn't have enough input methods, you can add one reasonably easily... A good deal of early-ish work on multilingual support in Emacs was done out of interest in editing technical text, which is basically the same problem as more-or-less complex natural language scripts (which deserve support anyway, of course).

Can you really ship slower?

In the end it’s a winner takes all market, and AWS needs to out-innovate azure to win.

And as customers of AWS we’re all looking forward to the next re:invent for new features, and we’re voting with our money buying huge amounts of AWS services.

Also, as a potential employee, I would always sign with the company that has positive cashflow through customers that pay for shipped value, rather than a company with a great code base, but a bad sales track record.

I don't see how feudalism would help there, beside ensuring the people you are talking about are killing themselves in the fields.

I also don't see how more and more regulations ensure this won't happen, as it most likely had the exact opposite effect: prevent new wealth from establishing itself (high regulation preventing blooming wealth from building enough momentum to escape taxes) and enshrines "old" money. Regulations gives a clear advantage to people already established.

Providing a license is not surrendering copyright -- in fact, just the opposite. In order for anyone to make a copy of a copyrighted work they must have a license to do so. The license sets the terms of that copying. This is the fundamental aspect all copyright.

I've had a bias in this direction for quite a while. When learning about neurodegenerative diseases back in college over a decade ago my conclusion at the time was that something metabolic was going on. Nothing else made sense to me as an explanation for how symptoms and pathology for a disease could show up after 60ish years. At that time I couldn't figure out how to make the link though, so it was a leap.

I was in a lab meeting maybe 4 years ago or so and my PI had just come back from a conference on Alzheimer's. He reported back that groups had started investigating the role of mitochondrial dysfunction in the disease and had been able to find that lineages with variants in genes related to mitochondria and energy homoeostasis were far more likely to have or develop Alzheimer's. I haven't kept an eye on progress in that line of research, but it is in line with what is being reported/speculated here.

Finally, a couple of years ago I ran into the father of someone I went to middle school with and I learned that he was a biochemist. Somehow the conversation wound around to the challenge of understanding neurodegenerative diseases. I asked him for his take on a disease that only presents after 60ish years. His immediate answer was DNA damage during mitosis. But neuron's don't divide. And then it hit me. There IS something that is still dividing inside the neurons! It is the mitochondria! The other possibility is the astrocytes, the microglia, or some other mitotic cell population in the brain, but the mitochondria really stand out as fitting both the fact the neurons don't divide and the instinct from a veteran biochemist that something that takes so long to appear must be related to DNA damage.
But that’s because the AWS teams are presumably shouldering the burden, then.

You may already be aware of it, but the Bittle from Petoi may be of interest:

https://www.petoi.com/

Bittle is obviously not of the same size as the Go1 so won't be suited to the same practical tasks but if you're looking at exploring the control aspects it would serve as a good platform to learn on (for a substantially lower initial outlay). Petoi has the OpenCat repo and there are plenty of ways to hook it up to additional sensors or a remote system for more advanced guidance etc.

Edit: Mine arrived on Friday. It's great, although putting it together had a few challenges (the springs are a tough fit, but people figured workarounds on the forum)
Wow that is a huge breach of privacy and trust. Given the other recent discussion about apps being installed without consent or notification on smartphones (https://news.ycombinator.com/item?id=27558500) and Tim Cook’s absurd claims about side loading (https://news.ycombinator.com/item?id=27565002), it seems like it is time for consumers to get devices back under their control rather than continuing to cede ground.
That all sounds dysfunctional. I hear tech jobs are hot right now; you should start looking.
Ah sure, yes we did not need to conflate vectors and matrices with arrays and I sometimes wonder if we made the wrong choice there.

I guess I'd say that then someone would get to own the syntax

[a, b, c]

it'd either be a vector of a non-mathematical array and whichever choice was made, someone would be unhappy. I think not too much was lost by having them be the same thing, but the ship has sailed anyways.

On SSDs? 32 is way off, the Samsung 470 had 256MB RAM cache and the 860 Pro a whopping 4GB for the top model.

Although they started removing it entirely for NVMe SSDs, I guess the direct transfer speed is enough to not need a cache at all.
Ok got it. I figured that might be what you were getting at. I definitely experience the same thing. Isn’t it crazy though that in order to feel more relaxed on our day off, we need to actually spend that chunk of time in work mode.

Regarding your performance work, you've nerd sniped me into looking for analytical tricks to speed it up ;) We'll see...

Regarding the readability, I suppose it's a matter of taste at this point, but if I swapped `import numpy as np` for `from numpy import newaxis, exp, sqrt`, then IMO, the numpy is more readable:

A = a[newaxis]
M = exp(1j * k * sqrt(A**2 + A.T**2))

But then my tastes also run towards preferring the handwritten definitions to be in terms of vectors and transposes instead of elements and indices, at least until you get to many indexed tensors.

Side note: any idea why the python and fortran are exp(i k... while the julia is exp((100 +i) i...)? Is it something I overlooked?

How to Approach Different Industries?
I've studied computer science and have been working for a number of years in the cyber security sector while also still enjoying saas development.
I'd like to explore other industries to understand industry specific challenges where IT/engineering could support and build a business out of this.

What would be the best way to explore other industries?
No, no need to worry. Coronal mass ejections causing geomagnetic storms are really something to worry about but this thing is just a piece of rock flying around the Sun at very far distances (from our point of view). It is coming no closer than eleven astronomical units to Sun (1 AU is the mean distance of Earth to Sun).
I’m not seeing the relation other than it’s also in space (so is the earth and everything on it by the way).

Why would this do anything to spike solar flares? It’s a lump of rock and ice 130km across, further out than Saturn. What possible mechanism do you think there is that would cause that to occur?
But would you ever invest in an idea that could be easily copied?
Its interesting that Netflix built their systems in a way that assumes the underlying platform is unstable. With Chaos Monkey and other systems they made sure things are resilient to flakey behaviour.
That sounds almost as amazing as what I inherited once upon a time: an 1985 Oldsmobile Delta 88 Royale Brougham LS with dark silver fleck craptastic paint, chrome everything, limo tint, gutless 307 V8 LV2 motor with roller lifter, 4 mobster body-capacity trunk, predictable drifting characteristics, and seating for 5-6 Americans. It was once of the most comfortable cars ever, but the crushed merlot velour interior (as featured in a Traci Lords' film) created so much static, it's a wonder more gas station fires and localized lightning didn't occur.

Your work environment does sound pretty crazy, but that has nothing to do with sprints or project based work.
I'm not sure I understand why you say it's about not paying people? VFX jobs are usually reasonably well paying and usually with good overtime rules.
Is vehicle/part failure the main driver of replacement though? At least around here it seems more like a lot of people lease, especially among EV owners. As EV tech rolls out it seems like people don’t want the Old Thing anymore which may at least initially cause more turn over among EV cars?

It's entirely dependent. This is also partially why "do you have a good manager" is included. I've had a few that absolutely will be in the line of fire first, and not make their team do anything they wouldn't do themselves.

From experience: a good team/manager, when forced to do this, will often freely be first on call, give you a day off after if you had an incident at night or let you sleep in til noon or later without complaint, etc.

If you are European or similar country with better working conditions/employee laws, it will be less painful. IIRC, in US salaried tech employees can effectively have unlimited unpaid overtime as a specific exemption.
> and a 12 year old car is no problem for anyone but the people at the wall street journal in my opinion.

They're doing economic reporting -- they're pointing out that the median age is going up, which is bad for auto makers.

I don't think they're telling anyone that is a bad thing for individuals, just for the economy as a whole.
Well, Common Lisp or Racket are a lot faster than Python, too, and both are general-purpose languages which has many advantages over a language specific for numerical computing.

AWS does not have to be "lots of UI" and "Windows admins" -- Terraform, CloudFormation, and other infra-as-code solution are totally a thing, and bring modern, UI-less practices to to infrastructure services. If you are in the company which has corporate culture of "let's use AWS todaly like we used Windows 20 years ago" it may seem that the whole world is like that.. but it is not, there are plenty of other companies with different cultures!

Re "OS to deal with cloud-scale problems at the ground level - in the kernel" -- I cannot make sense of that. Why on earth would it matter which OS do services use? For all that I care, Amazon could rewrite DynamoDB using AmigaOS and I would not even notice. It is all the same HTTP calls -- and this is one of the good things about the system. People can use AWS services from windows, linux, mac, mobile, even things like FreeRTOS, using any programming language they like. I guess you can create one more OS which is designed with AWS use in mind, but I doubt it will be a big game changer.

Dear Professor Hewitt,

I’m sorry for my comment at https://news.ycombinator.com/item?id=27537500. In hindsight, I realize now that it sounded like I was making fun of you. I didn’t intend to do that at all. I think your concerns about Wikipedia were surprising, and I only meant to express surprise.

Thank you for taking the time to patiently explain to everyone your ideas about improbability. It takes a lot of courage to present an argument the way you’ve been doing in these threads. And you present your proofs in mathematical form here, which is rare, and worthy.
