Osmium··on Security Begins at the Home Router
In particular, recommendations for consumer routers would be welcome. Last time this came up, the line seemed to be "consumer routers are trash, if you want security you have to use an enterprise router." There might be some truth in this, but it isn't helpful. Surely not all consumer routers are equally bad?
Osmium··on The Promise of CBD, the Cannabis Chemical That Won’t Get You High
> it's also one of the reasons why I "enjoy" drinking chamomile tea: It tastes so bad, it gotta be healthy

Each to their own, I really enjoy the taste of chamomile tea :)

Agreed that it's a good thing for medicine not to taste 'good' though, especially for medicines that happen to enhance appetite...

Osmium··on Finding a Therapist
> The people it doesn't help are the people who put no effort into the process.

I’ve heard this repeated a lot. I have no doubt this is true for some people (maybe even the majority of people for which therapy doesn’t work, I don’t know). However, I wouldn’t want to claim this is the only reason. Especially since it’s a great effort for many people to even make it to therapy in the first place. They are making an effort. And it’s disheartening to then turn around and tell them they’re the problem if it doesn’t work.

Osmium··on Finding a Therapist
Your own comment would have been a lot better without its first sentence and that "idiot" clause :) I didn't find the parent's comment rude or trollish.

It seems clear that therapy can help people. It also seems clear it is not a panacea, and that it can depend on both the person seeking therapy and the therapist, as well as the reason for therapy. It sounds like the parent was sharing their own experiences, which are just as valid as your own.

If we elevate therapy and therapists to be beyond criticism, all we end up with is a cult. Take the parent's comment on credentials and licensing: I'm sure that we want our therapists to be licensed, using evidence-based techniques, but that doesn't mean all credentials are created equally, or that because someone has credentials automatically means that they can be helpful to you personally.

Osmium··on Georges Lemaître, the Belgian priest who discovered the universe is expanding
Interestingly, I made the same error. I think because that first comma is misplaced (vs, say, a colon), making me expect a second comma later.
Osmium··on Supersharp Images from New VLT Adaptive Optics
> or to know what the mapping is

Agreed! This is important. Scale bars would be nice too, as well as info on other pre-/post-processing. Usually all this is in an associated publication (which is hopefully freely available), since it usually takes a surprising amount of information to fully understand an image like this.

> beauty is lost on me > pretty picture

Pick one ;) Sometimes we can find things beautiful without fully understanding them (arguably this is always the case). For me, knowing whether it’s derived from real measurements is what matters. But everyone’s threshold is different. I’ve seen beautiful simulated data too, but that’s something different again — more like the beauty of an equation to me.

Osmium··on Supersharp Images from New VLT Adaptive Optics
I see this question a lot. I used to have an obsession with 'true color'; images felt fake otherwise. Artificial.

I'm a working scientist now, and my view has changed. I realize how limited our senses are. How much of the world--of the universe--I'd miss by restricting it to just what my eyes can see natively. Even among colors that I can see, but perhaps the signal is too faint ... I'm a lot more tolerant of color-mapped images now. I don't see them as artificial anymore, but as beautiful and transcendental. A window into a hyper-spectral world normally invisible to me. It's really something special. I wish I could share this perspective with more people.

Osmium··on 2018 MacBook Pro Review
That sounds pretty awful. Luckily I haven’t personally had any keyboard troubles (I’ve had it since release and travel with it frequently), but if I had I’d probably be a lot less positive about it (:

> I'd go further and say that Apple isn't basing their hardware strategy on the needs of any real person.

Real person here! I love the USB-C only approach. I love being able to charge from either side of my laptop, and I love having single cable to plug in at my desk for RAID/monitor/ethernet/charging/etc. I want my laptop minimal; if I want it to do more, I can add more.

Osmium··on 2018 MacBook Pro Review
I love the keyboard, and I code all day.

It's actually my favorite keyboard of any I've used with the exception of the current-gen external Apple keyboards. I enjoy the light-touch and low key travel required to type. I find the typing more pleasant and kinder on my hands.

Osmium··on Computing normals for 3D Bézier curves
It seems to me that it's a computer analog to bike-shedding[1]. A problem 'easy' enough that people feel comfortable explaining it. Same reason there are lots of articles on linear algebra, FFTs, etc. or even why there are so many static site generators etc. -- they occupy that sweet spot of something useful, not entirely trivial, but not too complex that they reduce their audience.

[With that said, I think this is actually a really nice article, and well-presented.]

Osmium··on Random Points on a Sphere
I finally read some Greg Egan recently and was not disappointed (started with 'Axiomatic' which is a collection of short stories, I'm not sure if this is the best place to start but I found it to be a good introduction...haven't read an author who could write a story around Cantor sets before!).
Osmium··on High-power thermoelectric generator utilises thermal difference of only 5°C
Yes, that's almost certainly wrong (or, at least, should no longer be called a nanowire). A length of 0.25 nm is of the order of the interatomic distance between a single pair of Si atoms.

> but the ideology and technology of the Culture -- there's the entire value of the series.

> fascinatingly, banks captures the essence of the Culture in a way that few other writers can do with any concept of such complexity.

Yes, I couldn't have put it better myself :)

The Culture is the main character; the unifying theme. And it is fascinating. More-so than any one person or plot or event. And this surprises me: I generally don't enjoy world-building for the sake of world-building, which many authors have done or attempt to do. But this is something else. It's very special.

Osmium··on Nancy Pearl’s Rule of 50 for dropping a bad book
> Consider Phlebas I had read and enjoyed, but it seemed flat, uninspired and uninteresting on second reading.

For what it's worth, Consider Phlebas was my introduction to Banks: I found it ok. Something like an above-average sci-fi action movie. I enjoyed reading it, and it left an impression, but not a spectacular one. However, I stuck with Banks, and by the time I got to Use of Weapons ... that was a book that really did floor me. I think Banks is really something special. Enlightening, maybe. Even if he can be uneven at times, I still haven't read anyone else quite like him.

Perhaps if I read it again, the magic wouldn't work a second time, I don't know, but it sure did work the first time.

Osmium··on WWDC 2018 What's New in Swift Recap
They do provide a public dashboard for tracking progress to ABI stability: https://swift.org/abi-stability/

Whether it turns out there are things missing from that list, who knows, but they're definitely getting closer.

Osmium··on WWDC 2018 What's New in Swift Recap
Note that you can disable this feature, however in most cases it's probably best not to -- the new hasher functionality is actually really cool and a good improvement on the old behavior. If you want to disable it, I think it's a compiler flag.

[* said as someone who's implemented probably a ton of poor hash functions in their time]

Osmium··on The New Yorker has formed a union
Unions (usually) put a floor on your salary, not a ceiling. I'm a member of a union, and my salary is a good 20-30% above the union minimum.

I've never had to contact my union (though I've benefited from it indirectly), but my sense is that they're useful as advocates for their members interests, especially in larger organizations. Often, this can even be for simple "common sense" proposals that are not controversial, but are difficult for individual employees to make happen. Navigating the bureaucracy of large organizations is not easy, and unions help with this (by creating an additional bureaucracy admittedly, so they're not a perfect solution).

Osmium··on Show HN: A Native Art Gallery for the Mac
Very nice! Request: art gallery-like legends next to the artwork, with title/artist/date (I imagine this would only work with a curated source of art, but if I ever used something like this, I'd like to learn something too).
Osmium··on Google I/O'18: Keynote Livestream [video]
You can imagine a feedback loop though:

Some people use Gmail auto-replies more > Other people therefore receive emails in the style of these auto-replies > These other people then start manually sending emails according to this style > More people then become happier using auto-reply (since it produces replies in a style they've come to expect)

In this way, an auto-reply feature, even if used by only a subset of the population would start to move language trends.

Maybe there's nothing wrong with this, I don't know. But there is a feedback loop there, which means there's a blurrier line than we'd like between "this AI algorithm does what I'd expect" to "my expectations have become shaped by AI algorithms."

Osmium··on Ask HN: Who do you trust most with your data?
P(your data compromised) = 1 - P(storage provider never hacked)^(number of storage providers)

All else equal, using more storage providers increases your risk of exposure, not decreases it. And for most classes of sensitive data, the loss of any of that data can still cause problems, e.g. imagine health records... if only 1/5th of your patient data was hacked, that would still be a very bad situation (and before anyone asks, yes people use Dropbox for this[1]).

Osmium··on Making the Touch Bar useful by abandoning Apple guidelines
> You may already know this but you can just tap and hold on one of the brightness or volume buttons and just slide the way you want and the button morphs into a slider.

Yes, this is actually one of the few things I actively like about the touch bar.

I love that Apple is trying something new with laptops, but sadly it's been mostly a dud for me too. I'd take Face ID + a T2 chip (like iMac Pro) any day. The fundamental problem is you don't tend to look at the keyboard when you're using a computer; there isn't enough incentive to do so, so it always feels a bit like a chore to use.

I think there's a kernel of a good idea here, but the current implementation isn't it.

Edit: Reading this article, I've realized all I really want from the touch bar is a permanent Dock. The Dock is important enough to always be on your screen, and it'd be really useful to have at a touch.

Osmium··on Ask HN: What books do you keep on your desk?
I would be interested to know if there was a 'gold standard'/'bible' of finance books for someone who knows very little, but doesn't mind a technical read.
