I switched from Evernote to Notion 6 months ago. Their block-based editing system drives me up the wall. But, they really nailed their media integration in a way nobody else has, so I continue to use it.
Not OP, but I prefer the paradigm of phabricator diffs over GitHub PRs. It papers over git's inability to have unnamed branches and makes stacked diffs much easier. It also makes it easier to do "no branches, everything is on master" development, which I feel is superior whenever it's possible.
I'd buy an Intel mac from 2015. The modern ones all have their well-documented problems. The ARM based macs will almost certainly have a small period of instability and incompatibility when they first launch, just like the Intel macs did.
I agree about not getting an ARM Mac on launch day, for the reasons you’ve cited. But I have a 2015 Pro for work, and a 2020 Air for myself. The Air is a fantastic machine, and I wouldn’t hesitate to recommend it again, even after the ARM announcement.
What do you think of the keyboard? I'm still lovingly holding on to my 2015 MBP which has keys that actually travel. For context, the last new Mac keyboard I tried was the butterfly variant.
Lots of people actually liked the 2016 keyboards, less travel is fine for many people, including me. The real problem as the susceptibility to debris breaking keys, and not being easily fixable.
So the new MacBook keyboards seemed to have the debris issue licked, and a little more travel. That’s all I need, but if you want more travel I can see it’s not there for you yet.
Your premise is flawed. Yellow shirts don't kill people. Not wearing a mask does not kill people. Letting a TSA officer fondle your groin doesn't save people's lives. It's all security theater.
"Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."
>"Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."
Whether or not you think masks help, this is wildly over-dramatic thing to say about an order to wear a mask in public temporarily. I'd even say it disrespects the quote.
We also have a society that requires clothing. And that doesn't even KILL people. Yet we handcuff -> jail nudists anyway. One major exception is pretty much 97% of the state of Oregon, where that is 100% legal.
This is demonstrably false, as we now know for a fact that wearing a mask does reduce the risk of both catching the virus yourself and transmitting it to other people. Even if you don't care about your own well-being, common courtesy dictates you should care about the well-being of others. Failing to do so may indeed get them killed.
It's not a core foundation of our entire civilization, it's a quote by Benjamin Franklin and the actual context in which it was said doesn't even support your argument[0]. I guarantee that if a plague were spreading through early America (in an alternate universe where they knew what epidemiology was, obviously) Ben Franklin wouldn't be on the side of people protesting quarantines and masks.
Handcuffs if you don't wear the mask, in enclosed public spaces. Heaven forbid your right to be maskless be suspended so those of us who don't want to risk lung damage or death can be safe.
Sure :) I understand you . For me Mac became unusable on a new setup until I install my FM. I wrote it for myself in the first place and I am using it heavily daily. Working on it for quite some time now. I do not plan it 'small' as another BS app over there. This one should really 'just work' in the best mac traditions of SJ we know: elegant for beginner and powerful for advanced in the same time, with high quality standard in mind as the first priority.
So consider yourself being signed up for the first notifications, you won't miss the 'revolution' ;)
Hacker News were very helpful and supportive resource for me and I think the first public announcements are deserve to be here.
Watch the whole video. They managed to keep the laptop ice cold with a custom heatsink, but even then only managed to eek out a 12% performance improvement. As it turns out, Apple actually knows what they're doing.
I think you misunderstood that. They hit the power limit, which just means after deciding the thermal limit Apple saw no reason to give it a CPU power supply that can go much beyond that. (Which might be either a hardware or a software limitation.)
From what I understand it's the CPU power management/frequency profile that is limiting it. Even when satisfying the thermal requirements they were still getting sub-par performance because presumably the CPU was being limited in software anyway.
A combination of good cooling + a tweaked power management profile to accommodate the better thermals should give a substantial performance increase.
Doing it within the operating system is suicidal as a malfunction of the OS (whether accidental or due to malware) would force the machine to operate beyond its thermal limits and potentially damage itself.
This is another misunderstanding/misconnection. "kernel_task" is used to report "missing" CPU time so the CPU usage accounting remains consistent even when the CPU is throttled. That does not mean either the kernel or userland have any input to the thermal throttling functions.
There's also multiple levels of protection and throttling. At the lowest level, various ICs on the board (e.g. power regulators) will turn themselves off if they overheat. Somewhere above that, firmware will definitely exert /some/ control, to cover odd situations like the machine hanging while booting. Above that, the kernel or userspace can add another layer — but like each of the layers before, that layer can only lower the limits further.
Having thermal management in userland (and nowhere else) would be legal suicide. Imagine the lawsuits from people accidentally burning their legs...
I believe you are correct, although I did think that kernel_task was there to help cool the components down, and not simply as a devide to report throttled CPU usage consistently with unthrottled.
That said, I didn't mean to say that thermal throttling only happened in userland but rather that it did happen there, even though it might also happen elsewhere.
Within the context of this thread, this is relevant since in this case the CPU was not being thermally throttled as it was running cool, but something was still throttling the amount of power going to it.
I was merely suggesting that Nextgrid's affirmation that it must have been the firmware throttling the CPU is not necessarily true. Given that there is a software component to thermal management (or at least I thought so), it's only logical to assume that there may be a software component of whatever other throttling was occurring without it necessarily being suicidal as suggested.
> A combination of good cooling + a tweaked power management profile to accommodate the better thermals should give a substantial performance increase.
Give it a try and report back.
edit: Wow, HN has changed. There was a time when experimentation was encouraged here.
I don't think that's terribly useful. Regardless of how much processing power you can extract from the CPU, there is the parallel question of CPU lifetime.
You can see in the video how hot the CPU runs. If I remember correctly, a 20°C temperature increase halves the lifetime of electronics. "Normal" laptops tend to stick around 60°C-70°C. Apple apparently decided that halving or even quartering the CPU lifetime compared to that is fine.
That said, most MBA CPUs probably spend their CPU lifetime closer to idle. It'd be interesting to get temperature numbers for that. Still, it's worse than it could - and IMHO should - be.
The entire overclocking community also decided lifetime is secondary to performance, yet I still feel rather displeased with Apple deciding to make lifetime secondary to saving a few cents on a better cooling solution :D
Modifying the thermal & power management profile is very difficult as it would require reverse-engineering the firmware.
I guess a temporary hack would be to mess with the current sensing circuitry to make the machine believe the CPU is drawing less current that it actually is and encourage it to give it more power.
I have, but the fact the heatsink didn't event mount properly is kind of annoying... I agree, they know what they're doing, but I also wish they'd have designed better cooling.
They dropped the temperature under load by a good 10 degrees C just by milling a few mm off the heatsink so it actually made contact with the CPU... sure, that didn't increase the performance drastically, but it seems like a massive oversight on Apple's part
The problem is that the 13" MBP is over twice as fast in many benchmarks, but people think "if they had just put a better fan/heatsink on the air" they would be the same speed.
I wonder how much faster the 13" Pro would be if they did a similar setup.
In this[0] iFixit teardown (of last year's 13-inch, they don't have one for this year yet, but I assume the inside layout hasn't changed much), the cooling setup is a lot more traditional with a heatpipe from the CPU to the fan. I don't think it'd get a lot of benefit from the watercooling that LTT did (at least, without Apple's power profile taking over and throttling).
The only reason I can think of that Apple set up the MacBook Air like that was because it was supposed to be fanless and at the last second they couldn't figure out a way to eek out performance, so they added a fan where it would fit. That doesn't sound much like Apple's engineering though, so I don't know why they did it.
Because Apple limited the CPU to only be able to use x amount of Watts, because otherwise the cooling/the power consumption would be outside of their "product design goals".
But they probably still advertise "latest Intel CPU with xyz GHz and blah blah amount of cores.". But that would be like buying a Ferrari with advertised "an engine capable of gazillion horsepowers", but having it limited to only be able to go up to 2000 RPM...
> But they probably still advertise "latest Intel CPU with xyz GHz and blah blah amount of cores."
From what I have seen of LTT, their biggest criticism of Apple is their tendency to emphasize the turbo boost clock speed when the CPU is nearly always being throttled (presumably below the base clock speed) due to the machine being unable to dissipate the heat.
If you want to see an example of Apple advertising the turbo boost speed in very large print, check out the "Overview" page on the 13" MacBook Pro.
Crop dusting is still a thing. I live in the middle of nowhere and there are several strips of flat grassland that are landing strips for crop dusters.
Sorry, I didn't mean to argue that wifi is deadly (because power is so much lower), I'm merely agreeing with the parent that the sun is deadly. I think the links to cancer are strong enough to warrant the term.
