> How about real fruit juice? Much healthier.

Most fresh squeezed fruit juices have comparable levels of sugar to soda. They may have some extra vitamins but they are not terribly 'healthy'.

Indeed. Fruit is "healthy" because it has fiber in it. Fruit juice removes the fiber, making it basically the same thing as soda.

Also people tend to consume a lot more when in juice form. A 16oz glass of OJ is ~8 oranges worth of juice.

It doesn't have to for example if you made orange juice from an orange and didn't filter it. Eat the orange or juice it it's pretty close.

Who says eating the orange is healthy? Still lots of fructose, and these days you're not going to get scurvy if you skip it.

The obesity epidemic is probably not being caused by people binging on whole fruits, however.

> Use tabs, goddammit.

Use ASCII's `RECORD`, `GROUP` and `UNIT` separators, they were literally designed for it.

Which key to I press on the keyboard for those when I want to hand edit docs for quick testing?

In terminal / vim:

    Record separator => C-v C-^
    Unit separator => C-v C-_
in emacs I think you can use C-q in place of C-v

Well, the first three you mentioned are for providing power to other chips, the last 4 are RF amplifiers, they aren't really related.

Why you need (or want) multiple power management ICs: they are likely powering separate zones of the board which may have very different power requirements, e.g. need different voltages, need to be able to power up or down separately, or need particularly clean power.

Why you need multiple RF amplifiers: Almost all phone today run on many different cellular frequencies and protocols, a quick look at the specs indicates the iPhone 6 supports: 800Mhz, 850Mhz, 900Mhz, 1700Mhz, 1800Mhz, 1900Mhz, 2000Mhz, and 2100Mhz along with various different signaling schemes. You can't handle all that in a single RF pathway.

>need to be able to power up or down separately

Need to be able to power on the Data, MIC and Camera per the Court Order without waking up the rest of the phone :)

For what it's worth, there doesn't appear to be any proof that this person is whom they claim to be.

The question was asked but somewhat suspiciously dodged: https://www.reddit.com/r/Bitcoin/comments/3fe92x/im_ashley_b...


/u/MtGox_Adam is the same reddit account as previously used by the Mt.Gox CEO. Of course it's possible the account has been hacked.


I guess it depends on how 'core' is defined. A single core of an Intel CPU can work on 2 threads at a time, the power 8 can work on 8.

I assume that when most people think of 'single core' performance, they really mean 'single thread'. I think Intel's CPUs win out there, based on your linked benchmarks.


Wow, that is much, much, smaller than I thought it would be.

Anyone have a recent link on Reddit's infrastructure? Given the small size I would think it easily fits in memory so I'm a bit curious how they handle it.


This is the newest (2010) one I know of, and probably the one everyone's seen (I think it was HN back when it was first posted: http://highscalability.com/blog/2010/5/17/7-lessons-learned-...


Hopefully this results in improved syntax highlighting for Ruby.

Anyone know of any ongoing efforts in this area?


Well it's been opened up. Why not help contribute yourself?


> But it's worth remembering that Spotify's fundamental unit is the user playlist

I don't think that is true.

My interaction with Spotify is much more about listening to an artist or song and using 'more like this'. And the fundamental unit of sharing is 'friend x listened to this song'. If I know I like their tastes I tend to list to that song then, if I like it, listen to 'more like this'.

I spent about an hour earlier trying to use Apple Music via iTunes and left incredibly frustrated. I couldn't make it do anything I actually wanted it to do.

As a simple example, go to 'new' then, pick a genre from the incredibly awkwardly placed drop down, scroll down and you see 'top songs'. Cool, I thought, lets play the top songs from this genre! Except, as near as I can tell, there is actually no way to play those songs as a 'playlist'. You can click one at a time, and they play, but after each finishes it just stops.


Weird for me it seems exactly right. I tend to share and follow playlists not individual songs.

Also I have had no issue getting Apple Music to work the way I want including what you were trying to achieve. I just clicked on Top Songs and it opened as a playlist where after the first song finished it played the next one. Maybe you were clicking the indvidiual songs ?


> In fact, Safari is still the best browser when it comes to everything UI-related (animations, visual effects, …).

I use Safari for all my general browsing for one reason: It uses 1/2 to 1/5 the power that chrome does.


I doubt it will ever be as good as Safari, but Google is working on this: http://www.macrumors.com/2015/06/12/chrome-os-x-performance-...


Unfortunately the biggest problem by far is video playback and for whatever reason they seem to refuse to fix the problem.

Here is a simple test I just ran:

Using https://github.com/erkserkserks/h264ify for blocking VP9

2015 rMBP 13", 3.1Ghz i7, 16GB (defaults to software rasterization in chrome)

https://www.youtube.com/watch?v=nK9Im1eP3DI (1080p60 video)

Power is CPU Package Total (core + GPU).

Chrome VP9: 26W

Chrome VP9 + Force GPU Acceleration: 28W

Chrome h264: 19W

Chrome h264 + Force GPU Acceleration: 13W

Safari: 4W

Additional comments:

This is all in window at the default 'theater mode' size of youtube. I can't full screen either of the VP9 options without completely maxing out the CPU, dropping frames and during my laptop into a frying pan. Its really hot even in window with chrome VP9 using ~175% CPU.


Glad to see some hard numbers on Chrome video performance compared to Safari. I like Chrome because I like the integration with Google services and separate user profiles so I have 2 sessions going at once, but I often have to take Hangout meetings in Safari because Safari doesn't turn my laptop into a hairdryer heating element.

I am curious, though, do the Chrome devs have access to the video APIs that the Safari people would?


Any idea how does it achieve that?


There is no reason for h264 decode to take much power at all, it's all done in hardware now (or should be done in hardware).

In other words, Safari's power number isn't surprising but I don't know how chrome manages to use so much processing power. Even my cell phone can decode 1080p60 without catching fire but chrome manages to bring a $2200 laptop to it's knees doing it.


I wouldn't be at all surprised that it would light up with the phone off too, or really with any metal material set on it. You've got a free antenna set above an already noisy circuit: the Arduino plugged into a laptop via USB. Putting a metal cover over the antenna could easily be enough to increase the field strength.
