Most of "enjoying time with your kids" is less about what you do and the fact you're there to do it.

It's about building the memories and the trust (in both directions) that anchors the family together. That'll pay off as they grow older and come into their own identities and start to drift away from you into their own lives.

It's partly about setting up opportunities for the big events that people idealize and have nostalgia for. If you're not there, you can't have those great experiences.

It's partly about having the bad experiences. Sometimes those matter more in the long run for building the deep, meaningful, and lasting relationship.

The day-to-day often sucks and often isn't "enjoyed". But the cumulative results of the time and the good and the bad - that takes long-term investment.

I'm not sure about the 3rd Ed, but the 2nd Ed had a much cheaper edition in a red soft cover and slightly smaller size, presumably cheaper recycled paper and no bells and whistles. It was distributed in India and developing countries and by all appearances it was totally legit, also accompanied by a label forbidding the sale in "western" world, where presumably they wanted to adjust prices to the higher income. Of course it was just a matter of time before it would land on Ebay sellers pages and elsewhere.

Ask HN: How to get started with understanding LLMs for biotechnology?
Hi HN!

I’m trying to use the next couple of weeks to dive into biotech applications of LLMs. But i’m running into an issue where most of this is in nature publications et al - and barely any demos / githubs.

Specific areas I’m interested are

- protein synthesis basics
- drug discovery advances
- bacterial strain development

Eg : I found this paper talking about protein embeddings (https://academic.oup.com/bib/article/24/1/bbac619/6987820?login=false)

Any pointers to companies / resources / githubs / code / blogs or even a high level overview of what to look for would be super helpful!

I got my phd in Communication and when I taught interpersonal communication, one of the articles we would have students read had an example of an American who was in Austria for a year or two. He was at a party talking to an Austrian friend when the Austrian's girlfriend came over. She stared using the informal "you." Later he asked her why she had decided to use the informal and she said, "I don't know. I just did it. You were talking with my boyfriend so I assumed I was on the same level as him." https://www.google.com/books/edition/Language_Shock/xOE4nPuW...

What I do in these situations (assuming the job is still in the foreground, and can be interrupted), is suspend the task with ctrl+z and resume with `fg`, chaining it with some other command:

fg; notify-send "done"

This uses the "job control" feature of `bash`, so it requires no extra setup. Your approach has the simple advantage however, that once it's set up, it just works, automatically.

Technology as in “applied science” applies to every industry
That's why the ontological framing is important- notice that 'powerful' doesn't mean anything inherently. Being, on the other hand, is necessary and inescapable for any metaphysical framework. To have anything, being must exist, necessarily. Therefore, to imagine the greatest possible being, seems not so much a stretch, compared to an arbitrary characteristic, such as 'power'. That there is a must 'powerful universe' does not seem a priori necessary, whereas insofar as existance exists, there is necessarily a greatest possible being. That is not to say that you can get to any meaningful conception of a God from that ontological framework, only that the it is only an argument when it is framed ontologically- once you stretch it to other domains, the inherent strength of the argument fails.

But the whole point is that 1) at peak solar times electricity is free (meaning wholly insufficient storage) and 2) the upfront cost of battery storage is rather prohibitive right now, while a hydrogen system is (I'd naively assume) technologically simple.

Where this comes into play is with the repeated calls for new nuclear plants - nobody in their right mind will bet against solar and battery electric storage on a 30 years timescale, and so nobody is building those.

> making the substance in the article weaker.

Less hard, to be more precise [1]. “Strong” and “weak” are way imprecise terms in engineering.

The simplest example is whether it’s strong under pressure (a brick is, a rope isn’t) or under tension (a rope is, a brick isn’t), but there are tons of other properties that are an indicator of strength of a material (https://en.wikipedia.org/wiki/Strength_of_materials), and this may beat diamond in some of them.

Reading https://en.wikipedia.org/wiki/Material_properties_of_diamond, diamond isn’t particularly tough, and we don’t really know its tensile strength, so this is less hard, but may have higher toughness or higher tensile strength.

[1] reading Wikipedia, even that isn’t simple: “There are three main types of hardness measurements: scratch, indentation, and rebound. Within each of these classes of measurement there are individual measurement scales. For practical reasons conversion tables are used to convert between one scale and another.”
"Unit" and "Integration" (and E2E) are the most bullshit "technical" terms we have to deal with on a regular basis as an industry. At best, they can only tell you that integration tests are on average more liberal in their use of system calls than unit tests, that is if the codebase in question even has both.

While this dev you encountered might have had no idea what they were doing, a most charitable explanation is that they may subscribe to the idea that the "unit" is a business usecase within a single service (often a 1:1 correspondence with an endpoint, but sometimes even more than one, e.g. a form upload with a separate signed upload step to a 3rd party service).

FWIW the concept of small/medium/large as presented in the Google testing blog is a much more useful denomination.
First, note my correction to the mistake in the above 'Afterthought'. Brain wasn't in gear.

Thanks for the info. My German is far from perfect so I don't claim any authority on the matter.

Most of my time in a German-speaking environment was in Austria (Wien) and that was now some years ago. Back when I was learning the language it was always stressed to me not to use du even with friends as it would be deemed as unwanted or excessive familiarity and could be taken as an offense.

That said, from my limited experience there's are significant cultural differences between, say, Berlin and Wien with the latter being more formal and reserved (or it was so when I was living there two decades ago). Thus I find your observation interesting, so I'm now quite curious to see what cultural shifts if any have taken place in Wien since then.

My first time there was in the early 1980s whilst Communism was still in place, so back then there was essentially no movement of people between Czechoslovakia, Hungary, etc. and Austria. When I went back in the early 1990 and lived there at various times for about a decade I noticed a definite cultural shift which the locals put down to the movement of people from ex-communist counties such as Slovenia. However I can't say I noticed any shift in the language, but then that's not surprising as most people I worked or dealt with were better at English than I was in German.

No doubt things have become more informal almost everywhere these days so I'm not surprised that there has been a shift in German usage just as there has been in English—even in my lifetime it's been very noticeable.

English is a dog of language, it's slipshod, inconsistent and all over the place (it beats me how anyone who is not a native speaker ever learns it). The point I was making about thou/du illustrates the problem with English quite well, English-speakers are notoriously bad at learning second languages so why make, say, learning German even more complex by not explaining actual parallels between the two languages? It seems no one cares much about the details these days.

As an aside, in English you goes for everything—friends, relatives, one's dog, even inanimate objects. Thus it's interesting to note slang has picked up the cudgels and fought back with a colloquial use of the second person with youse. Many wince at this word and consider it uncouth and uneducated, but when one thinks about it, it makes sense when talking to a small group of friends. Seems funny really, we English speakers chucked out the perfectly good second-person (and respectable) word thou and at least in some circles have replaced it with the uncouth youse. Clearly, modern English is missing something important by using you for the singular and plural forms of the second person.

That said, I wouldn't never rely on the App Store to surface my app on its own, it's ridiculous.

> Just because most metric unit ratios are a power of ten doesn’t mean there is no ratio.

There is one metric unit for distance (the meter). Likewise, there is one unit for force (the Newton); one for energy (the Joule); one for mass (the kilogram); one for electric charge (the Coulomb); etc.

> You can divide a meter into four 25 centimeter pieces, or five 2 decimeter pieces.

The parent specifically asked for "whole numbers". The term "centi" means hundredth, and "deci" means tenth, so your examples are 25/100 metres and 2/10 metres, which are not whole numbers. If we allow fractions (which we should!) then sure, we can make any rational ratio we like.

> Just because most metric unit ratios are a power of ten doesn’t mean there is no ratio.

All ratios between units in metric/SI are 1, by design. You're probably referencing power-of-ten ratios between prefixes, like "centi", "kilo", "mega", "micro", etc. Those are not units, they're just an alternative way of writing numbers. For example, 2km = 2000m because 2k = 2000 (by definition of k); nothing to do with units, which in both cases are meters. Likewise, both "2 dozen meters" and "24 meters" are in units of meters; the first isn't in a separate unit of "dozen meters".

> Alternatively, you could restrict US units to just yards if you wanted

I've never seen anyone restrict to using yards; usually the restriction is to feet, like the foot-pound-second system https://en.wikipedia.org/wiki/Foot%E2%80%93pound%E2%80%93sec...

> and get nearly the same inconvenient behavior as meters

The explicit convenience of using meters (rather than the implicit convenience of not having any length conversions) is that all of its conversion factors to combinations of other units are one, by definition. For example:

Pushing a force over a distance takes energy (see https://en.wikipedia.org/wiki/Work_(physics) ) so distance = energy / force. In metric, 1 meter = 1 Joule per Newton. In contrast, 1 yard = 0.968 calories per pound-force, which is less convenient.

Newton's second law says force = mass × acceleration, so distance = force × time² / mass. In metric, 1 meter = 1 Newton second² per kilogram. In contrast, 1 yard = 2.978 pound-force second² per slug, which is less convenient.

etc.

I actually wrote a page about this on my blog a while ago http://www.chriswarbo.net/projects/units/metric_red_herring....

I’ve never seen a distro that didn’t grant read permission to everyone for /sbin and /usr/sbin.

In any event, it doesn’t really make sense to me to deny read access for any executables, so long as you don’t also deny read access to Python or a C compiler.

Really, if permission mode bits are the only thing preventing damage from such tools your vulnerability is not within your path or mode bits.

Alin, are you ok to share the specs of that server? I'm interested mainly because I'm a server guy and have a bunch of stuff at Hetzner, but nothing (yet) big enough to be US$600 for a single server. :)
No. In the same way you shouldn't be in charge of managing whether your electrical devices can electrocute you.

When it comes to actual safety issues, it's better that things not work when unsafe.

Not too long ago there was a story on HN about hospital patients getting sick from bacterial growth in ice machines.

I meant, you could actually execute the experiment yourself and see what happens. You don’t have to trust me, rather just do it and find out how quickly your comment is nuked. You won’t get into any trouble other than your comment being deleted…probably. The truth is easy to discern by just running the experiment if you want, but I’m guessing you have some cognitive bias that you’d rather have confirmed instead?

I have created a demonstration of Hamilton's stationary action with interactive diagrams, (supported with discussion of the mathematics that is involved).

Interestingly: it is possible to go in all forward steps from Newtonian mechanics to Hamilton's stationary action. That is the approach of this demonstration. (How Hamilton's stationary action came into the physics community is quite a convoluted story. With benefit of hindsight: a transparent exposition is possible.)

Recommended:
read the following two articles in this order:
Introduction to calculus of variations:
http://cleonis.nl/physics/phys256/calculus_variations.php

Hamilton's stationary action:
http://cleonis.nl/physics/phys256/energy_position_equation.p...

The path from F=ma to Hamilton's stationary action goes in two stages:
1) Derivation of the work-energy theorem from F=ma
2) Demonstration that in cases where the work-energy theorem holds good Hamilton's stationary action will hold good also

Also interesting:
Within the scope of Hamilton's stationary action there are also classes of cases such that the true trajectory corresponds to a maximum of Hamilton's action.

In the demonstration it is shown for which classes of cases the stationary point corresponds to a minimum of Hamilton's action, and for which classes to a maximum.

The point is: it is not about minimization.
The actual criterion is that which both have in common:
As you sweep out variation: in the variation space the true trajectory is the one with the property that the derivative of Hamilton's action is zero. The interactive diagrams illustrate why that property holds good (it follows from the work-energy theorem).

Hamilton's stationary action is a mathematical property. When the derivative of the kinetic energy matches the derivative of the potential energy: then the derivative of Hamilton's action is zero.
