Nesting is useful, but not as useful as you think.

It’s great for keeping your pseudo-selectors close to your selectors. It’s great for faking scoping, by wrapping a whole file in the whole file in a single classname labelling your component.

But nesting also increases specificity and can distribute the name of a selector token across multiple places within the source file making debugging much harder.

If you use nesting as an aid to writing more CSS faster, you’re using it wrong. If you use it as an aid to constructing what would be a neat CSS file without nesting, then you’re doing it right.
The argument for advertising is that it's so difficult for a new entrant to a market to challenge an entrenched incumbent, unless they can advertise.

I honestly don't know if that argument holds water.

I thought the listed passage from The Sea-Wolf made my point clear. Here is the key point again;

But,—and there it is,—we want to live and move, though we have no reason to, because it happens that it is the nature of life to live and move, to want to live and move. If it were not for this, life would be dead. It is because of this life that is in you that you dream of your immortality. The life that is in you is alive and wants to go on being alive for ever.

"Natural Law" gives me the right for Survival. The Theory of Evolution/Survival of the Fittest lays out the environment/circumstances which control/modulate this but the instinct to Survive is inborn in all living organisms.

Another passage from The Sea-Wolf which drives home the point;

[Hump] “God made you well,” I said.

[Wolf Larsen] “Did he?” he answered. “I have often thought so myself, and wondered why.”

“Purpose—” I began.

“Utility,” he interrupted. “This body was made for use. These muscles were made to grip, and tear, and destroy living things that get between me and life. But have you thought of the other living things? They, too, have muscles, of one kind and another, made to grip, and tear, and destroy; and when they come between me and life, I out-grip them, out-tear them, out-destroy them. Purpose does not explain that. Utility does.”

“It is not beautiful,” I protested.

“Life isn’t, you mean,” he smiled. “Yet you say I was made well.

...

“Stability, equilibrium,” he said, relaxing on the instant and sinking his body back into repose. “Feet with which to clutch the ground, legs to stand on and to help withstand, while with arms and hands, teeth and nails, I struggle to kill and to be not killed. Purpose? Utility is the better word.”

I do think Steam can charge more because it offers more good services for users than any other app/game store: search/discovery features that have gotten better over time, per game communities/mods, tons of social features including a marketplace, multiple platform support, and their customer service. Sure their fee might discourage some developers, but if there is a case to be made for 30%, this is it. It all works because there is competition between Steam/GOG/Itch/Epic/etc.. on multiple open platforms in a pretty well differentiated way.
How do you reconcile that claim with the polytheistic nature of religion in Rome, and it's practice of folding other religions into it, as it absorbed conquered cultures?

Your parallels to 20th century governments miss the mark as much as the claims you are criticizing.
> On the other hand laptops are terrible for ergonomics and daily usage anyway, it's unfortunately we've moved so far into laptops from desktops and it doesn't seem so common to dock them and use an external keyboard..

Especially considering that nowadays "docking" is pluggin in an USB-C cable from a monitor that:
- is used as a large external display
- powers and recharges the laptop
- acts as an USB hub, with external keyboard, mouse and webcam.

If I want I can go outside to have a meeting and when I want to code, I go back to my home office. And when I commute to the work office, I can work on the train. And when I get there, I plug it in the same setup as home.

> It is recommended to learn if subtransactions are used in your systems. If they are, it does not immediately mean that they need to be eliminated – it all depends on the risks of your particular case. Evaluating such risks is a complex task that requires deep Postgres expertise, so if you need such an analysis, consider hiring a PostgreSQL expert.

It is quite disheartening that this essentially echoes this quote from the related blog post https://buttondown.email/nelhage/archive/22ab771c-25b4-4cd9-...:

> It is entirely possible to operate Postgres safely and with high performance and throughput at scale … but essentially the only way to do it is to have ready access to deep PostgreSQL experience and expertise on your team; people who Just Know where the landmines are because they’ve seen them before.

And https://blog.nelhage.com/post/some-opinionated-sql-takes/:

> My personal choice: MySQL

> The devil is in the details, but for me, as a default, and despite all these pet peeves, I would start with MySQL.

> As for Postgres, I have enormous respect for it and its engineering and capabilities, but, for me, it’s just too damn operationally scary. In my experience it’s much worse than MySQL for operational footguns and performance cliffs, where using it slightly wrong can utterly tank your performance or availability. In addition, because MySQL is, in my experience, more widely deployed, it’s easier to find and hire engineers with experience deploying and operating it. Postgres is a fine choice, especially if you already have expertise using it on your team, but I’ve personally been burned too many times.

Why should you need expert consultation in order to use core features, when other databases "just work" without all these caveats? Transaction ID exhaustion and VACUUM tuning comes to mind here.

Hey HN.

SnipRSS let you curate your own custom RSS feeds by clipping content from web pages using a browser extension (Chrome at the moment). We extract metadata from the page which you can edit before saving it a feed that can be used by anything consuming atom or jsonfeed.

We’re big advocates for RSS so have developed Snip to scratch our own itch. It’s a very simple product but solves a problem for us and customers of our other RSS tool https://fliprss.com.

It’s in beta and we know some areas need more work but it’s up and running and already getting some use so it would be great to get any feedback on the tool, pricing and any questions you have.

Thanks

Whenever I used Lisp for real projects over past two decades, the development was an order of magnitude faster and powerful. To stay on the positive.
I studied musicology with a focus on perception of sound.

As far as I understand it, we evolved to be able to perceive distinct colors because it's relevant to distinguish surfaces from another visually.

For auditory sensations on the other hand rough pitch estimations sufficed but relations between pitches (think of hearing 2 pitches. you probably won't know the exact note or frequency but have learned to recognize patterns in the relations between them - e.g. musical intervals) which comes down to periodicities in the signal turned out to be a lot more relevant or helpful.

As to why we needed to be able to relate pitches to one another:
Without looking up literature on the topic I hypothezise that it might be a byproduct of the way we calculate a single perceived pitch out of a harmonic frequency spectrum.

When hearing a note that is not a sinus wave in the frequency spectrum there are at least parts of the multiples of the base frequency.

Since we do something like frequency analysis by detecting periodicities our brain tries to determine a single pitch for the signal, which it does by calculating the base frequency of harmonic spectrum (this works even of only part of the harmonics are availabe.).

In order to do that the processing needs to treat the base frequency differently than the overtones.

Since overtones roughly correlate with western musical intervals and we needed the processing to get extract them. We might have gotten relative pitch perception and part od what is music as a byproduct.

Anecdata for this:
Try determining the existence and intervals of notes when the higher note is an octave or an octave and a fifth above the first one (1st and 2nd overtone). Depending on the instrument this can be quite hard.

Disclaimer: These are my interpretations / theories, but since I'm not working in this field, the literature might tell a different story.
> Everything that's used should be cached in RAM

This isn't guaranteed, depending on many factors.

> why would I want to remove the SD card after boot

It's unnecessary to remove it. It's more about reliability. SD cards are notoriously unreliable, and it could potentially fail after boot. Coupled with the previous point, it has happened multiple times that I wanted to login to troubleshoot the system, but cannot because the basic system binaries like `ls` are not cached in RAM (as you said these are not used for the normal operation of these unattended systems).

This is when RAM disk is very helpful: as long as the system is powered on, I have reasonable confidence that I can login and see what's going wrong. It's mostly because RAM is way more reliable, faster, and cheap enough to "waste" a few dozens megabytes for the entire base OS.

Also there're diskless PXE systems where you just load the OS from network only once upon boot.
What you say isn't factual. the article compares smallpox with covid, which is a mistake. But the virus is endemic and will be. There is no chance of herd immunity. Not with the flu, not with the cold and not with this. That is the current reality. Perhaps we will some day have the means, but until then, we have to let people live again.

> The angle and cosine start to lose their geometric intuition when we go beyond 3D

... they do?

"Geometry" in general loses intuition beyond 3D, but apart from that, angles between two vectors are probably the one thing that still remains intuitive in higher dimensions (since the two vectors can always be reduced to their common plane).
And at Purism.

It is almost as if life was full of compromises. Yeah I too want to do nothing, but still live in a mansion and have infinite money, but that's not part of the reality.

If remote work is the most important aspect of a job for you then you should look for fully remote job. You might need to compromise on some other aspect like pay.

If you just want to eliminate commuting then remote work is one option, but you could also just move closer to your office or change jobs to a company that has office closer to you or to a company that has office in a location you wish to move to.

Again there is nothing I "fail to grasp" about this. There are other jobs than the highest paying one and there are other options than to work than commuting two hours to an office. What you don't seem to grasp is that I am not fighting you and you are fighting some fantasy version of me.
Unstoppable Domains provide their own tlds. Also, for the user to reach the content of the domain it must first install an extension that would instruct the browser to which IP to send the request.

It takes a bit more than one screenshot for me to think "unmaintained", like one click to the Support page and another click for details on a bullet item takes me to https://franz.com/support/apple_silicon.lhtml and I'm at least assuaged that it isn't abandonware even though I'm not an Apple user. But in any case I still get a bad feeling from the ancient images and sympathize with similar negative reactions, whatever they are in detail; for you it's a sense of being unmaintained and for me it's a sense that they don't care very much about the product and aren't interested in attracting new customers. And this is just from the window chrome, looking at what the screenshots actually depict produces another set of emotions that I don't think anyone at either company cares about exploring. At least LispWorks' has syntax highlighting... (In case any employee happens to catch this, take a look at https://www.jetbrains.com/idea/ and compare.)
Your first step is to get yourself back into a mindset where you can rationally reason about things. To analogize, the problem is in the operating system (the mental processes that help you do things in your life) but you're running diagnostics on the higher-level processes (job, family, etc.). So what you do is you run the low-level repair algorithms. As everyone else says, talk to a therapist or counselor (which it sounds like you can afford) - there are even online services for this if the activation energy of finding a counselor in the normal way is too high. Finally, don't forget the more mundane things, in particular prioritize getting good sleep any way you can. Many (most?) of us have been in the same place - things can and will improve once you re-center yourself.

Sure, but I'm not saying everyone should adopt Nix; I'm saying the solution to problems caused by global mutable state is to avoid adding more global mutable state.

If 'apt-get dist-upgrade' is breaking the packages we pip-installed into /usr/local, I'd ask (a) why we're using two package managers, and (b) why 'put these files in these locations' is being solved implicitly by running imperative, non-deterministic commands to mutate things in-place, rather than e.g. extracting a .tar.gz of known-good dependencies.

I use Mac. I like the UI. And I firmly believe that there are great benefits when the hardware is made by the same company that made the OS.

I believe that Apple’s laptops are the best on thr market.

I also enjoy the apps. E.g. 1Password / Preview / Evernote / Skitch / Pingplotter / djay. great And Acorn. Acorn is great and I would really miss it if I switched back to Linux.

I love the fact that people can make a living of writing great apps for the OS I use. I gladly pay for that.

After ~10y straight of ThinkPad T-series, I won't be getting another one. The BS you have to go through to get firmware updates with important security and bug fixes is ridiculous. On paper they're in fwupd/LVFS but in practice it've very spotty. After a full day of trying other approaches, I eventually succumbed to installing Windows and Lenovo's adware-encriched update manager on a spare SSD just to be able to use my Thunderbolt port with my official Lenovo dock.

On top of that, every series have been getting worse and worse maintainability/extendability/serviciability for pretty every generation. The latest vanilla T-series are comparable to the first-gen Carbon-X1 in this regard.

NixOS has this feature, though you will have to rewrite parts of your configuration if you're using bleeding edge/nonstandard stuff.

I run automatic updates nightly, sometimes when I get back to the machine it's in init waiting for me to input my ZFS password.

NixOS is the last system you install, which is really nice. It's the Linux dist I've run the longest consecutive at home.
Let’s see if this sticks…
I still have an instance running 10.2.21 and no automatic upgrade happened (although it upgraded to 10.2.21 from 10.1 automatically a few months ago)

Right, so you explicitly acknowledge that the AGPL (based on the same free software definition) doesn't have this problem. So how is it a problem with the free software definition?

No. I am not surprised airlines try to mandate it though. They face existential problems in another lockdown. They also tried to advertise vaccination passes because that might allow them to operate.

> On desktops it mostly doesn't matter because you can shift the keyboard over relative to the screen.

It does matter. The arrow key cluster and numpad take a lot of space, which means the left side of the keyboard (where asdf / your left hand are) and your mouse have to be very far from each other. This leads to either putting the keyboard's letter key section in the center, making your mouse be uncomfortably far to the right, or having your mouse in a natural position for your right hand, leaving your left hand way out to the left. Over time this can (and did, to me) cause posture / muscle balance issues.

Currently I'm using the Microsoft Sculpt Wireless keyboard. https://www.microsoft.com/en-ww/accessories/products/keyboar.... The main keyboard with letters and two extra columns just to the right of the letters (with no gap) means everything can be positioned perfectly. The wireless numpad is there for when you need to use it. It's a very overpriced product at $100 but works wonderfully.

Also, in college I had a tiny desk with a cabinet underneath its left side, so my chair was offset to 60/40% of the way to the right. With a full size desktop keyboard with numpad, there literally wasn't enough space for my mouse, unless I moved the keyboard very far to the left. Thus causing the issues I mentioned above. That's what got me into tiny mechanical keyboards :) I'll admit it's a somewhat niche case, but there are probably still many millions of people in the world with a similar desk setup to that for whom a full size desktop keyboard is an unhealthy option.
>Consider suggesting a very lax but cheaper SLA to them, they might not care much, maybe it is just a check-box on their end?
