> Because it's my understanding that charging and keeping it all the way full shortens significantly its battery life compared to 80-85%. If you don't charge fully until just before the user's normal wakeup time you aren't keeping it all the way full all the time. You protect the battery lifespan and get a full charge at the beginning of the day, instead of having a battery that constantly holds less charge.

> If you don't charge fully until just before the user's normal wakeup time you aren't keeping it all the way full all the time. You keep repeating this and seem to ignore my observation that if the battery isn't drained below 80% when I plug it in, it will recharge it fully immediately . It will not wait until the user's wake-up time. And in my case, it's rare that the battery falls below 80%, so whenever I plug it…

Yet year after year, surveys show that more battery life is the feature people want in a phone the most.

Intentionally throttling the battery's ability to charge no matter what is going the wrong way.

I could trick you into adding a hardware key, then install a tampered version of Windows with it. (Also, the last time I looked, TPM keys could be grabbed with ~ $100 of hardware, but I think that's fixed by some newer standard.) But, yeah, it's not a big tradeoff in practice. I think their point was that Apple had to expend effort to enable the use case, which isn't "hostile" toward the use case.

> I could trick you into adding a hardware key, then install a tampered version of Windows with it. There are other issues as well. For instance, on a PC the security settings are applied per machine and not per partition, so you can't mix an unsigned OS on one partition with full security on another partition.

This wasn't true for a low-end Acer I bought a while ago, and it's not true on an Asus motherboard I use. You can add keys to the bios, and then it'll let you run with either key. That lets you use the grub shim key. On the Acer, you can even tell it to screw PKI, and just check that the hash of the bootloader hasn't changed.

Why does this posting have a rel=noreferrer tag, when others don’t?

Looks like jwz links also have a "noreferrer" tag added as well. https://news.ycombinator.com/item?id=3132752 New silent HN policy to avoid showing its users that some people don't like them.

This is extremely gross 'Dang, and I'm wondering how you can possibly defend doing this. Seriously, why are you going to these lengths to evade a soft-block on links to specific sites that very clearly and explicitly are communicating that they don't want HN's traffic?

In fairness, most instances of them doing that actually significantly increase the cost of evil maid hardware tampering attacks. If I could, I'd configure grub or whatever to serial-lock my Linux install to my desktop hardware (and keep a recovery key that would unlock it at another location).

> If I could, I'd configure grub or whatever to serial-lock my Linux install to my desktop hardware (and keep a recovery key that would unlock it at another location). This is the general idea behind TPM/Secure Boot, but as you present it, it just sounds like a headache for performing system recovery, at no obvious benefit for security. What's your threat model? In the 99.(9)% case it's a crook snatching the laptop,…

I don't really care if the desktop gets snatched. I'm more worried about old tax returns, the credentials stored in its password manager, etc. Breaking in twice (once to install a bump in the wire key logger, and once to walk away with the machine) would lead to at least 10x more payout for a burglar.

Also, ignoring what it is worth to the attacker, having to roll over all my credentials, freeze accounts, etc, etc, because my desktop was stolen would cost way more of my time than buying a new desktop (happily, the drive is encrypted).

The issue is that Apple isn’t giving anyone access to the tools to pair the parts, unless you give them all the information in advance, buy them at possibly inflated prices through their self repair program if they’re even available, and then have Apple remotely approve it afterwards (and this process only really works for individuals, 3rd party repair is more important as most people don’t have the skill)

If I was running a third-party unauthorized repair shop, then I'd care. However, I just don't see why I should care, as a customer. Also, I have trouble wrapping my head around the standpoint that people want to pay the Apple "it always sort of works" tax, then spend lots of extra time trying to save $50 on a repair.

When I mess around with hobby hardware, it's esoteric stuff, not readily-available laptops that are being built by the millions. For that, sometimes you need a volt-ohm meter, or diagnostic rigs.

Every few years I even bring some piece of a Linux box to a repair shop, to narrow down some fault.

However, Macs are all identical, so repairs boil down to "yank component, throw in the recycling shredder box, and (if you just replaced the mainboard) restore from iCloud Backup". Apple hardware switched over to being livestock, not pets a long time ago, so I'm not seeing the point in spending lots of effort on custom repairs (vs. replacing + recycling the bad components).

Going with the first link. The "best" phone is not globally available. The second "best" comes with three years of OS updates. I stopped reading there; three years is a much, much shorter lifespan than you get with iOS or MacOS. Also, say you have one of these phones, and are in a major city, then break it. How will you get the parts you need to repair it? How many hours will you be without a phone? With Apple phones…

I am sorry but you're missing the point here. I'm not arguing over better hardware (performance) or price. I am arguing over hack-ability; that's it. I hope you can understand that.

None of the machines on that list are more hackable than a Mac though.

Some are more "hackable" than an iPhone, but only in some strange symbolic way, since once you de-googled android is somehow more user-hostile than iOS and completely unhackable in practice (in the sense that I can't make it do what I want and also be usable as a daily driver that lets me do stuff like pay for stuff, use public transit, charge my car, park, or take an uber/lyft).

I'm a happy owner of a pine book pro, and a pc engines router; I get it. However, I don't think there are any viable Linux laptops or phones that compare favorably to the linux laptop + phone I had a decade ago.

To be clear, is this a description of your experience with Asahi Linux?

No; with MacOS running an Ubuntu Multipass VM. :-(

This raises interesting moral questions that I'm not sure I have an answer to. For one, I don't believe this place fosters a hostile environment, although it's definitely a place where people love to tell you how you're technically wrong about something. For another, I would guess that there are a very limited number of websites that would opt into this sort of anti-traffic behavior. Hacker news could certainly choos…

there is constant transphobia against Asahi contributors on display on this site. Every single article that gets to the frontpage will have dozens of vile posts in the deads and a couple sprinkled inbetween. I’m not sure if HN staff doesn’t care about it, agrees with them or simply isn’t aware. It’s not limited to the Asahi project, either. The site isn’t safe for queer folks.

I've managed to tick all your boxes on not one but two Lenovo ThinkPads. Ironically I've had trouble with suspend on my previous work Mac laptop running macOS. Also issues with WiFi on the same Mac laptop not present on other devices. Every single hardware failure within warranty I've had on both personal and work laptops have been Apple - LCD, battery, mainboard, dvd drive, just to name a few. Yet all the others I'v…

The end of the intel mac laptop line models were the worst laptops I've ever used. My last one went through 2 screens, the battery swelled, it couldn't charge fast enough to stay on while plugged in (and the CPU ran at 10% perf while charging, but only if plugged in on the left side).

Also, at any given time 6 of the keyboard buttons stuck, and the touchbar constantly phantom pressed the siri button when I pressed backspace. It got under 90 minutes of battery when brand new. It reliably kernel panicked on resume 1-2 times a week. It was also loud and hot.

Maybe I should give lenovo another try.

They completely screwed me over on a warranty repair right after the IBM acquisition. When I got the laptop back after over a month, it was diagnosed "no fault detected" and had a new symptom: it leaked high voltage from the backlight transformer into to the case during boot shocking the heck out of me!!!

Also, when I look at their web page, I always have the problem that they offer too many sub-configurations, and there isn't a button that says: "just give me the one that definitely runs Linux with the taint bit turned off, and only contains components that have had stable OSS drivers for over a year, and whose BOM hasn't changed for at least 12 months".

Ironically, Apple's web page is pretty close to having a de facto button like that.
