I think groundwave propagation only happens reliably at the extreme low end of the HF spectrum, and is mostly associated with medium and long waves (160m ham band & AM radio for example).

For most of the HF spectrum reflections off the ionosphere are the main useful propagation mode. At the short end (like CB radio) bouncing of the ionosphere is harder so line-of-sight is more common.

My UK ISP (Hyperoptic) _only_ offers CG-NAT for IPv4 unless you buy an IPv4 address (by buy, I mean rent) but they do also give you a nice big IPv6 range, so you could use that (I host my one and only home hosted service on IPv6).
Super bad issue, just merely voicing I think they will fix it. Everyone seems to go into this shark feeding frenzy of how they are terrible and will never fix it. I get tired of that shit and merely pointing out this is a well run big company and they are going to fix it.

The mob mentality in these comments is overwhelming sometimes.

how many people actually need to fly outside of traveling for work? in America, a high tax on gasoline would actually be devastating to the livelihood of a lot of poor citizens. being priced out of frequent air travel doesn't sound like a massive hardship.

I took the train from Toulouse to Paris last summer and it was very pleasant—especially in comparison to air travel. A few hours of picturesque landscapes with plenty of legroom, baggage space, and opportunities to walk around. I think it’s too bad that we can’t seem to get that working here in the US. (See, eg, California high speed rail project...)

>1. How can one find out about their shadow profiles that have been created by FB?

Funny how this question always seems to generate distracting and misdirecting responses.

The simple fact that detractors seem unwilling to address is that FB and countless other internet advertisers are stalking billions of unaware people on a micro level using all sorts of shady and opaque techniques and compiling the most detailed psychological profiles on the most number of people in history.

The public has only just begun to contemplate the massive national security and mental health problems that this mass stalking and manipulation creates.

As an oftentimes Emacs user and a sometimes Vim user, I need more keys not less. I especially want more modifiers in consistent locations. Laptops frequently move these around, put a fn key where ctrl normally goes, or don’t even provide a ctrl key for the right hand. Apple does all of this.

Further, why does the spacebar have to be so wide? It makes the Alt and System (mapped to Hyper, Meta, leader keys whatever) harder to reach without looking. Microsoft offers an new ergo keyboard with a split keyboard, but then doesn’t provide a way to map the left and right pieces to separate bindings.
It's very sensitive, I brush the Siri activation and "focus URL bar" all the time, at best causing a break in my flow while I get back to where I was and at worst losing data because I'm now typing into the void. I also have to look at it to figure out where things are, which slows me down.

Physical keys were a huge improvement. I'd have loved it if it was programmable keys with little LED displays, but being a flat, easily triggered surface makes it a big loss for me.

Nuclear trains sounds badass but no I'm not aware of them existing.

I have a conceptual issue with the Touch Bar. I’m struggling to understand what the Touch bar can achieve that a toolbar that exists on the screen would not be better at. Especially on a laptop with the great trackpads that the MacBooks have.

About the only benefit is that it doesn’t take up screen space, but in that case a single trackpad gesture which brings up a touchbar like toolbar right where your mouse pointer is seems like a much nicer input mechanism.

FPTP is one of the most efficient and fundamental enemies of democracy, plaguing the USA. Everyone agrees partisanship is bad, people looooove a “bipartisan” bill, but FPTP mathematically converges on a two party system, always. It fuels tribalism and us-vs-them mentality like nothing else and perpetuates a political aristocracy through perverse incentives and hamstrung competition. To see this in effect, consider that a major party is incentivised to fund fringe opposition parties which will steal votes from the main rival. Ask yourself how healthy that democracy can be.

There are many alternatives and RCV might not be your first choice, but make no mistake about it: FPTP has to go. Stat.
> People who like to hate on it, didn't invest time in learning that you can program it to show what you want.

I already program different things most of my time. Why tale away my convenience (aka part of keyboard) and make me program something on top of what I'm already programming?

Three years on Touch Bar is still a solution in search of a compelling problem.

That's not what it is like at all, though. I would say your approach is more similar to "my kid is being bullied at a local community pool, so instead of trying to address the bullying issue occurring to my kid directly, I will simply try to institute a bunch of rules to make that local pool a 'bully-free zone'".

Method for Emulating Higher-Kinded Types in Rust
Yes, I finally installed it via Flatpak. What a fun adventure! First, I had to install Flatpak with apt. Then, I downloaded the Foliate .flatpakref. I installed it with `flatpack install com.github.johnfactotum.Foliate.flatpakref`, which worked the first time!

No, it didn't. Of course, Flatpak let me know that my user account didn't have the ability to configure the remote repositories the Foliate flatpakref specified. I could have searched for the right way to do it, but installing as root seemed to work, and it runs fine as a regular user, too!

But, of course, it doesn't. It doesn't have the ability to open files from most folders. I see by searching that you set sandbox permissions in an application manifest file, but I'm not sure I'm that attached to doing any more of this.

I second this recommendation. I'm a big fan of Grant's material. Some of it blurs the line between actual, technical "sales advice" and a more generic sort of almost "self help" kind of thing, but I have found it valuable in either case.

I discovered Udemy's 1.25x and 1.5x speed last week. It certainly helped.
> The Touch Bar is fantastic to adjust tuneables in GarageBand, without the gorilla arm or wobbly screen effect you get on touchscreens.

I futzed around with the touch bar in Logic when I got one and wrote it off almost immediately. Logic Remote (which works with GarageBand, AFAIK) already exists and works with an iPad. Clear labels, clear text, manipulating multiple elements easily at once--it's a better solution than what they tried to wedge in with the touch bar.

The bigger problem with the touch bar is that, as a developer, I end up hitting the touch bar controls all the time. VSCode "helpfully" has previous tab/next tab buttons on it--and so when I try to hit 2 or 3 on the keyboard, sometimes I brush against them and suddenly I'm disoriented and typing in a completely different tab.

This machine is a work laptop. (Typically my music stuff is done on a 2012 rMBP, which is why I already had Logic and Logic Remote set up.) When I started, I asked for a half-the-price Thinkpad on which to run FC30 and was denied because "everyone else uses a Mac." I love the job but between the garbage touchbar and the hand-wreckingly shallow keyboard travel the computer they gave me it's easily the worst part of my day.

Isaac Asimov Foundation novel series predicted this.

"The premise of the stories is that, in the waning days of a future Galactic Empire, the mathematician Hari Seldon spends his life developing a theory of psychohistory, a new and effective mathematical sociology. Using statistical laws of mass action, it can predict the future of large populations." [1]

“Selling at a loss” is about the marginal cost versus the price. I’m not “labeling” anything. That’s just what it means.

It’s perfectly valid to talk about overall profitability when accounting for non-marginal costs, but that’s not the phrase you use to talk about it, and saying that some units are sold at a loss while others are not is nonsensical in that context.
What do you think happens if we don’t dramatically reduce our carbon emissions in a very short period of time? I’ll give you a hint: it doesn’t resemble anything like the “advancement of humankind.”
> I will simply try to institute a bunch of rules to make that local pool a 'bully-free zone'

That sounds like a great idea for a pool to implement, and I would feel better about taking my kid there vs. the local arcade that just shrugged their shoulders and said "what do you want, if they don't get bullied here, they'll get bullied elsewhere."
Not really privacy related but I would ask them why they allowed a fucking lunatic to livestream a mass killing spree, why they didn't do anything to shut down the stream despite numerous people alerting them to what was going on, why their systems couldn't detect near duplicates of said content in the days, weeks and months that followed and finally, why they would allow absolutely anyone to start live streaming to audiences of potential tens of thousands to begin with. This was a disaster waiting to happen and I'm betting Facebook knew damn well that their technology, processes and culture were in no way equipped to deal with it. This is a rant but as someone who grew up in Christchurch I can't help but feel that they've learned nothing and done even less.

I will get in touch once I finish the section on Posit. I would appreciate some feedback! I'm writing in my language, but hopefully the google translator will work well.

Gustation is being too ambitious trying to reinvent the whole floating point framework. I think he should focus in what really matters: the compact encoding. A lot of application could save memory bandwidth using some kind of posit inspired format. A pack/unpack unit that converted the posit encoding to floating point inside the core would could be game changing.

He also proposed a good idea on code ergonomic: Make the accumulator a type (quire in the posit). Making the programmer aware of the accumulator can lead to better to code.

By the way, reading the Kahan work in floating point I could understand why Gustafson want's to avoid the IEEE. The Kahan implementation favored Intel, not necessarily the community.

Anyway. My point of views are from the hardware side of the things. The format seems to have some arithmetic properties that might be useful for mathematicians.
Next in the agenda: stealing energy from lightning.
None of which work very well, and most are completely broken. The only ones that completely work are CLJ/CLJS/CLJR's internal implementations, so you have to pull in all of Clojure just to read EDN from java, for example.

Transit is a much better choice here, but even that tends to be a bit non-idiomatic in languages like Python. That's not really the fault of Transit though, languages are just too different to have a single communication protocol work flawlessly between them all.
Great pointers. Thanks.
I never suggested that Bitcoin or Blockchain were entirely hype. I'm suggesting that many uses of them, and many articles about them, are, and HN treats them accordingly. I'm talking about the 23rd article on "let's do medical records but On The Blockchain, which will solve every problem with medical records". I'm talking about people who seriously suggest that Bitcoin will make existing currency and governments obsolete. I'm talking about comments that decry the slightest criticism or moderation as "the nattering nabobs of negativism".

Ah, that's interesting.. I was going to comment saying good riddance to it, since it was more expensive than the air, less power and just felt like it was out of place.. sure if it were _cheaper_ than the air, then great.. but I couldn't see a reason why anyone would buy it. Of course, hadn't realised it was fanless and lighter!
The engineering culture is not solely determined by the innovations the company has come up with, so I don't really see the point of the question you ask, with regards to the statement you quoted.

When you say that "most of the innovations [...] have been widely seen in the sysadmin community as negative", well, that can only be true in your own sysadmin community. If you replace "innovation" by "contribution", and make the list include everything RH works on (SELinux, NM and systemd are really a tiny part of it), the sentence becomes factually incorrect, even in your own sysadmin community (I hope).

Also, systemd was not created by RH (LP was not employed by RH at the time), and SELinux is from the NSA's TRUSIX. Labeling SELinux as a "negative innovation" is very weird (not that whole sentence isn't).

When you say that RH's only "positive tech" is Ansible, but that it was an acquisition, that's true for mostly everything RH participates in (Ansible, but also systemd, OpenStack, Ceph, CoreOS, GlusterFS, KVM, LVM/DM, gcc, gdb, systemd etc... were acquisitions or acqui-hires), so I really don't see your point. Does the fact that all of this software originated from somewhere else than RH negates the existence their engineering culture ?

For the first two principles... in OOP they are just guidelines operating at the layer of business logic. There are programming languages/styles that implement these "principles" as laws all the way down to primitive components.

See what I wrote about composition. I also have an example about a Car and engine class later in the thread.

Function Composition > Dependency Injection.

> ...I agree with your comments on Liskov Substitution Principle, that the fact it's even possible is a weakness in OOP type systems.

It's not actually a weakness in the type system. It's the weakness in the language. The language should never allow for such types to be constructed. Basically Inheritance is not compatible with the type checker. You get rid of inheritance, you get rid of this problem.
> There are reports of animals being able to predict earthquakes before they occur, and even records of other kinds of electromagnetic activity before quakes.

There have been all kinds of tests with animals but so far, all animal behaviour that looks like predicting earthquakes is only their sensitivity to low amplitude-high speed P (pressure) waves, which humans usually don't feel.
I don't know why people are mentioning CSS as if only special types of resources can be cached with ETags. ETags can be used on HTML documents or TXT files or whatever. It doesn't matter what type of file it is.
I get it that this is a joke, but more seriously I'd argue most labor is "region locked". Likely to within a few dozen miles of where you live.

It's actually fairly difficult to just buy labor from another region without doing the equivalent of "buying a regional console" (i.e. building a local office/factory, where people actually speak the right language).
Is it impossible to have a removable Magsafe cable?
Thanks for the explanation. That makes sense and seems pretty reasonable. The company should certainly have the opportunity to fix the vulnerability before it's made public and could be exploited.

Considering that Zoom ultimately decided not to correct the issue I suspect you're right.
I am a touch typist. I never look down at the keyboard, ever. The only time the Touch Bar is involved is when I accidentally switch tabs because the Touch Bar buttons trip even while you're pressing the 2 or 3 key on the keyboard, and then I'm lost in a different tab than the one I was working on in the first place.

Is there a preset that never shows anything on the touch bar, ever, except for the Escape key and the "global" brightness/volume buttons? Can this be done in, like, five seconds?

If not, then I might Frisbee this computer straight out the window. If so, I would love to know how.

> Touch Bar is useless to me.

I don't get it, the rest of your comment is mostly positive?
Your view is one kind of ECS. Another view is "structuring data to be cache-friendly". Another is "data feels better when modeled and accessed in relational fashion". Yet another is "composition over inheritance taken up to 11".

You can do all 4 of those at the same time!
What's the deal with that URL that links to "pageok"? Just a dead website or deeper joke?
Yet that person can still be an incredibly pleasant person to get coffee with. OTOH, you can have absolutely nothing in common with someone and even disagree with their life philosophy on a fundamental level yet they can be a perfectly fine person to work with.

"We are friends outside of a work setting" just doesn't correlate to "we work well together." What "we work well together" correlates to is actually "they are professional and respectful, they can do their job, and they have a good work ethic."
macOS never seems to be a priority at Mozilla, which kind of sucks. Another power management issue is video decoding. Even when I force YouTube to play .mp4 instead of VP9, my battery use is still 2-3x higher on Firefox than Safari, despite H264 acceleration being easily available via VideoToolBox, and VideoToolBox has been available since 2011 (Lion) or 2012 (Mountain Lion).

Hi. I work for Mozilla. Firefox for Android is not dead. You are free to continue using it. It will continue to support add-ons, and it will receive regular security updates and bugfixes for at least the next year.

We are focusing all new feature development in Firefox Preview, but we're continuing to support Firefox for Android as an Extended Support Release while we build Preview.

And, for what it's worth, we do understand how important extensions are to folks, and we are taking that into account in our planning.

A bit of a sidenote before I address your point directly: do you have a source confirming that all those companies that favor regional pricing for their games use labor from "underprivileged" markets?

As for why we shouldn't be able to, there are two good reasons:

1. If everything is priced at a regular price, no one in "underprivileged" markets will be able to afford those games, so cue piracy.

2. If everything is priced at the price point of "underprivileged" markets, it makes zero sense to produce those games, as it would mean that the company will surely go broke by doing so.

I really don't see the problem with any of this stuff.

I like physical escape keys, I really don't want expensive Bluetooth headphones, and I like having a headphone jack on my phone. I also like being able to repair and upgrade my equipment.

So what do I do? I don't buy Apple stuff.

Then I read discussions like this one and chuckle at all the people griping about all these things, and then continuing to buy and use stuff from the most hacker-unfriendly company on the planet. It's almost like they want to suffer.

Thankfully, Apple is not a monopoly, or even close to one, and there's lots of alternatives (which of course have their own downsides, but not for basic stuff like these issues), so none of this stuff bothers me, and I wonder what anti-consumer action they'll take next to piss people off so I can laugh about it.
