> but shouldn't Lambda be incentivized to produce excellent graduates because that increases the credit rating (so to speak) of their ISAs and in turn the market value?

[from the article]

> The moment Lambda started selling off the contracts, their incentives completely flipped. Their income was then derived from generating ISAs, meaning, the more, the better. Enroll as many students as possible. Of course, if no one ends up getting jobs, investors will eventually stop buying the Lambda ISAs, but that would all happen a long ways down the road.

As with most financial sins, it's short-term profits over long-term sustainability.
The fact that the battery had to be replaced 3 times in 3 years seems very odd.

An average owner would likely never have it replaced.
...the inferential procedure of Bayesian statistics is to assume a prior distribution and a probability model for data and then use probability theory to determine the posterior. But if these steps, or something approximating them, are necessary, if you can’t just look at your data and come up with a subjective posterior distribution, then how is it reasonable to suppose that you could able to come up with an unassailable subjective distribution before seeing the data?

Is the point to end up with an "unassailable subjective distribution"? I believe the power of Bayesian thinking is that you can take a subjective prior, which is necessarily assailable in its subjectivity, and then combine it with data. The result is something that is better than either the subjective prior alone or the likelihood estimator gleaned from data alone.

> you have to implement a private internal PKI for those servers so they're not getting public certs

This would also involve setting up a custom CA and distributing your CA cert to all machines that should be able to access the page. Good luck with that!

All of this is a ridiculous amount of effort to set up and maintain. It's a lot easier to just make the internal domains accessible to the internet and be done with it.

The effect being that networks are being nudged into exposing a lot more surface to the internet - and this somehow in the name of more security.
It does not, but crowding in a few names would definitely affect it. The graph would look really different if 70% of the portfolios hold TSLA.

> The flaw of your philosophy, in my view, is that you're just sweeping the tricky parts under the carpet by introducing concepts of "utility" and "right goal" and "society intends".

Sure, picking the "right" utility function is one of the hardest parts of utilitarianism. FWIW, I don't think maximizing agency is a different concept so much as a specific utility function that avoids some of the common pitfalls of strict utilitarianism (utility sinks: the person who gets enormous happiness from cannibalism). In other words you could imagine Agency as the "reasonable person" standard applied to the value of a choice. This still has flaws, but, IMO fewer than many other framings.

Some people might also find this to be similar to optimizing for the most "positive rights" across society, but I dislike that framing because the idea of positive vs. negative rights is silly, any right can be framed as positive or negative.

> Should a billionaire be able to spend $1m for the health of his/her child (maximize agency / freedom), or should the society put that money to "maximum utility" and spending it to help several (poorer) children (with illnesses that are less expensive to treat but still life threatening).

Note that giving a poor person money such that they can choose to treat their child's disease also increases agency! If you want to dive deep into this, I think that the marginal value of a dollar is probably logarithmic, or at least inverse quadratic or something, so a tax scheme modeled to tax top brackets in such a way that then improves the situation of those less off (pick your method: national healthcare, UBI, etc.) increases overall agency.
> Definitely makes me respect The Wire Cutter much more.

I'll probably respect them more when they stop hypocritically linking to Amazon.

The article implies that, but it's not true.
Indeed that is a very important difference. But in the absence of something truly open and free, Dreams is still incredibly empowering.

I suspect that a truly open platform/distribution would never realistically exist alongside something of this quality. It's a nice idea but it just wouldn't happen.

Something simple enough to be good and free is probably also not going to catch the attention of this generation of budding creatives.

There is a more formal description of systems thinking (see 'Thinking in Systems', Donella H. Meadows, for examples) that describe systems as components driving feedback loops and how they generate equilibrium or degenerate states, and where the best leverage is to alter the states of those systems. But I have a feeling it's yet another topic that's been diluted by consult-speak.
"Rust is making waves!"

Rust ranks lower than Delphi on TIOBE, isn't used in a single aerospace, defense, or critical application. Ada has been for almost 40 years, is backward compatible to Ada '83, and has a proof subset (SPARK).

Those waves look more like pond ripples caused by a light breeze.

How about, "Rust - now with bigger pond ripples."

What the first image of an Earth-like planet will look like
We have a few institutions that are close to being considered legendary across the planet: NHS and BBC spring to mind. Neither of those two are perfect but they are both ground breaking and a bit subversive.

I doubt anyone not from these shores (UK) would ever peg the UKoGB as a hot bed of left wing leaning types. Our stereotype abroad is pretty fixed and pretty obvious () and also encouraged by us: tourism is a bloody good earner.

We (people in the UK) now find ourselves as rabid defenders of a left wing dream, despite our political leanings. You know why as well as I do, that we love our NHS. If I want to, I can wander into a hospital ER and will be seen to, without any discussion of money. When someone needs medical assistance, metal discs or bits of paper should not be involved - they are merely pretty things and not useful.

() I should point out here that the "British Scientists" meme in Russia (int al) is one we are aware of, and also laugh at and with. There are loads more: and we still laugh with you, because we love you.
> there has been a basic Spacewar! emulator in Java since 1997, but it only recreated the game on an abstract level, missing the intricacies of the display

Did this version actually emulate PDP-1 machine code, or was it a purely mechanical clone? Because if it's the latter, then that isn't an emulator.

Either way though, Spacewar is definitely one of those examples where the hardware directly impacts the experience. This is also why I am saddened by the fact that the only truly good CRT emulation I've personally witnessed is from Super Win The Game!, and since I believe that game is closed source, it unfortunately cannot be repurposed for other games or emulators. Unless you happen to know of a particularly good reshade implementation or something.

For a game like Super Metroid, the "CRT experience" essentially boils down to "a greater sense of atmosphere and an enhanced sense of depth in some of the sprites". Does this arguably improve the experience? Yes. But the core experience of Super Metroid is not lost if you can't experience it this way - I would argue Spacewar does lose a core part of its experience without that iconic display, and I absolutely believe we should make an effort to preserve that experience.

I've always felt bayesian statistics got more attention from researchers than was warranted (including today despite deterministic methods taking over the world) because it has a nice principled "theory of everything" starting point. But then of course you have to approximate the heck out of it to be able to solve it. Often far more than with other methods.

You do sound like you're in a great spot, congrats! I've tried to do the same thing and haven't made it there yet. I did start my own company hoping it would turn into a lifetime of being able to always do exactly what I wanted, but it didn't end up working out that way. It was a ton of fun and a ton of work, and I had to sell it and take a job so I could feed my family.

Would love to hear a little about how you're making ends meet and still doing what you want on your own. Are you selling software, doing contract work, making money some other way and doing software on the side...?

this is kind of the perfect example - in theory, the secondary market should correctly price the ISAs based on the quality of the students being graduated.

But there is a significant lag built in on the pricing. It would probably be a few cycles of students, and you wouldn't even know they're not getting good jobs for a number of months if not years. Especially given Austen's kind of a celeb, Lambda could raised a few bigger and bigger rounds in that time period - and their numbers would look fantastic to potential investors with the cash coming in up front. If they played it right, they could maybe even IPO before those secondary ISAs ever get properly priced. Financial innovation at its finest!
Many of the top 50 python libraries are wrapping a lot of code that is actually c, c++ or fortran. So I doubt that there is a lot of performance to be gained. Numpy is a good examples for that.

Just have the police start tracking down what warehouses counterfeit items came from, and getting search warrants to search them.

Apart from the fact that this would directly reduce the number of counterfeit's... repeatedly shutting down warehouses for searches would kill Amazon's bottom line. Cleaning up after the police would kill Amazon's bottom line. Etc.

Nim would be really competitive in the gamedev/graphics field if there was a standard library that you can use without the GC. (Technically you can turn off the GC entirely, but you can’t use the current standard library without it.) The language’s especially good for gamedev because of its extensive metaprogramming facilities, a sane build system (which lets you write build scripts with a subset of Nim itself), and the fact that you can load C/C++ libraries with ease.

Related to this one, has anyone identified an equivalent font for what was used in the Apollo CSM and LM cockpits?
Thanks! you gave me one thing to check. The certs are indeed made for 10 years validity, the idea being that they should just make the demo work for a long time, even if it is with a certificate warning.

I don't think it's worth the effort of setting up all the automatic renewal process with Let's Encrypt for what amounts to a quick static code example... so in principle I wanted to avoid having to set that up.

The contents of this article means that soon this 2-year maximum will become a 13-month maximum, right?

Is there any way to create these specific-purpose certs with some kind of "private use" or "development use" flag that allows not having to re-create them so soon? 13 months looks too short of a time period, I'm afraid nobody will remember to refresh the fake certs and the demos will break... for really no good reason (related to the code itself)

The Constant Q Transforms uses bins that are spaced on a log scale like musical notes. So the bins corresponds better to how humans perceive pitch. You wont waste hundreds of bins to the high frequencies.

Calculating CQT can be roughly as fast as FFT.

I'm old enough to remember the way technical interviews used to be, and they were just like this.

Back in 2001, I dropped out of tech and became a land surveyor for almost 10 years. Now, land surveying or civil engineering is not the same business at all as software development, but they are both technical and there is some overlap in terms of engineering and outcomes.

My technical test and interviews were all completed on the same office visit, and I got a decision in 24 hours! Just think about how incredible this would seem today. First, I was welcomed by an engineer who gave me an overview of the company. Then, I was taken to a conference room and given a trigonometry & statistics test that took about 45 minutes for me to complete. Then I waited in the engineering library and browsed books while they graded my test. When my results came back, I then proceeded to the interview proper. After that I was introduced to the CEO of the company and escorted to the lobby.

The very next morning, I got a FedEx envelope with a proper offer letter. They really needed a good instrument man and they got one in 24 hours. Throughout the entire process, everyone I interacted with was completely professional and prompt.

I commend researchers in this field. Ransomware has a tangible impact on lives, particularly in cases involving healthcare facilities, for instance. Such criminals deserve harsh response for the chaos they create.

Also, I can’t help but thinking that the global internet that we’ve created is highly irresponsible. That criminals with sufficient skill and means can anonymously pull off these kinds of crimes with little chance for pursuing justice is indication of some fundamental flaw in the internet’s design. While people should have the right to be anonymous, there’s simply too much potential for abuse by such criminals. I wonder if the internet is ripe for disruption via redesign of core protocols. As I recall, this has been discussed on hn previously but I’ve lost track of such research..

There's an interesting difference (for me) between the recharge requirements for my phone, iPad, and Kindle. I charge my phone most nights (it'll last into the second evening pretty reliably on a charge), my iPad once a week or so, and my Kindle fairly rarely. I do quite appreciate the long battery like of the Kindle (it's an old 4th gen eInk display model, which doesn't go a whole month any more with heavy use, but even used a lot it still gets well over 2-3 weeks out of a charge).

I sometimes consider investigating rooting/hacking a Kindle to make it closer to a PDA - I suspect it's got a lot more computing power than a Newton did...
It’s not the price that’s concerning; it’s having external dependancies.

Inhaling Fibers from Bedsheets
I have dark navy cotton bedsheets and over the past year I've noticed that the sheets "pill" or "shed" small fibers. These look like the typical tiny little microfibers that make up the dust everywhere indoors.

Recently I noticed that they leave residue on my hair. I've had a bit of a cough, and I noticed that - sorry for the graphic image - when I blow my nose I can see the tiny microfibers in the tissues if I look closely.

This is concerning because it means that these fibers are in my lungs. Also shows that dangers can be lurking where we least expect them. Has anyone experienced this, and can anyone recommend "safe" hypoallergenic bedsheets?
This doesn’t make any sense in the context of tools like Snowflake and BigQuery, where the allocation of compute is separated from the data itself. You can scale each of these use cases independently without cross-domain impact.

The data lake model seems to be more about not wanting to commit to a warehouse (for example: future proofing, looking at non-relational data, etc.).
Sure if the industrial weighing equipment leveraged is, say, a weigh-in-motion system with an acceptable GVW tolerance of +/-10% as described in NIST HB 44[1].

In any case, this toy detail was intended to snuff out the grandparent's presumption that 10x error in any arbitrary parameter is obvious. The difference between 6061 and 7075 is offered as a simple thought experiment in that they're both common alloys in industry, yet difficult to discern one from the other despite the latter having a zinc composition that's 20x greater in the best case (6061 = 0.25% max; 7075 = 5.1-6.1%; 20 ~= 5.1 / 0.25) as specified by ASTM B209[2].

Fact of the matter is a contractor was responsible for a build-to-print submarine. A particular drawing specified something-or-other with an off decimal value that escaped human detection during multiple engineering design reviews. Contractor had something-or-other manufactured to the exacting detail specs in said drawing and no doubt was able to provide supporting documentation in the form of material certificates of conformance and lot testing results...but all the precision instrumentation and manufacturing quality control in the world amounts to nothing if the basis of truth is fundamentally flawed...and it certainly didn't help that the only effective opportunity to detect catastrophic design error (not that it's a build-to-print contractor's responsibility to identify such subtle faults) was spot validation of a system-level key performance parameter that wouldn't have been possible until the entire system was fully assembled.
