Resampling is a rather more complex operation than you might think
Well, I actually studied signal processing at university, so I have an idea of what it takes to resample a sound. (I actually did it with images once, but it wasn't very fast - processing a 2D signal is very complicated).
For sounds it's easier since you can have very good and still very fast methods. PA may be picking between perfect-slow and very fast-bad (And no, if I can guess what the 'trivial' method does, I wouldn't recommend it)
But I guess some programs already resample to 48000 internally, like mplayer (and maybe they can do it inside the MP3 decoding process, simplifying it considerably)
You can't rely on SIMD instructions always being available
Nowadays? Yes, you can. The machine I bought in 2002 (Athlon XP) has SIMD instructions. You can pretty much count on any machine today having SSE
Unless you're using a machine older than that in which case PA is the smallest of your problems.
Or you can make the audio card run in the sampling rate of the audio file...
And resampling still does not justify the CPU usage (unless who did the resampling algorithm used a naive algorithm, which may be very well possible), especially with SIMD instructions.
Remember what the % CPU usage of winmodems was (with significantly worse processors)? And that's way more difficult than resampling a sound file
No VDPAU here, for an SD video mplayer uses ~10%CPU
I'll not reinstall PA here, but I've seen it use more than 10% cpu on a number of occasions (besides all the other problems)
I confess I tried to use PA. When using Ubuntu 9.04 PA lasted 1h on my machine, for 11.04 it clearly improved, it lasted almost a week before I uninstalled it.
No one in their right mind would ship Pulseaudio (amongst other things)
Right, nobody in their right mind would do that.
Except that everybody is doing it, and it works just fine. But the dinousars who got an opinion about pulsesaudio several years ago and don't know that these days pulseaudio works fine and provides features that nobody else does will never change their mind.
No, It doesn't work "just fine" No, my opinion is not based on an older version of PA. PA is bad NOW, before it was even worse
Except that everybody is doing it, and it works just fine.
Maybe that's why there are several discussions about removing/disabling PA from Ubuntu (and others)
provides features that nobody else does
Like what? Using more CPU for audio than for playing a video? (yes, I did this test) Increased delay from 'start playing' to actually playing (try it with mplayer)
So yeah, I guess I'm a dinossaur for wanting my SW to work without BS, without hogging my CPU and failing to work properly half of the time (again, newest version). Yeah, sound mixing, per app volume, makes me wonder when was the last time I needed that (especially with most apps having their own volume control)
Then on the next couple of years we get congestion at the 5GHz band
It's not about band, it's about intelligently using the resources. Unfortunately, 802.11g is very bad at this, 802.11n is better, still, I think there's a long way to go still...
I think you nailed it, "rapid prototyping is useful when you only need to make one of something, and you need it right now"
One thing I've heard about 3D printed things is that things made with it are very brittle, still, I know it's used for implants, I think they do a prototype then make it into a mold and cast something with other materials.
Here's what happens, young person with good heart tries to solve world problem with technology. Problem is, they never left their parent's basement.
They doesn't have the SLIGHTEST idea of the depth of the problems. They most likely lived in suburban America (or maybe Western Europe) and they think the whole world has a WalMart and they couldn't duct tape anything to save their lives...
Hence, they go and create water filters "for poor regions" for $100 a pop. Pro-tip: in poor regions, families don't make $100 PER YEAR
Really? You're gonna 3D print SHELLS for CRABS? A simple time + money calculation shows they're F.O.S. Not to mention the pollution aspects.
This idea may work if you stamp shells made from recycled paper+cardboard. I said MAY
3D print? It's time to leave the basement and go for a big adventure, like riding the subway.
What he's doing is being a publicity hound. He could walk into Apple, talk to Tim Cook, and have a box of them placed in his lap. I find these antics humorous and highly manipulative. He's a billionaire. He can fly in private jets anywhere in the world on a moments notice. He can buy some whole towns. Why would a billionaire stand in line all night long to get a cellphone that his company sells?
One final note. Be wary of the practical joker. Those around him should probably get ready to have him buy theirs as well, as a good gesture.
Yes, Woz, we'll miss you too.
Yes, he can do all that. But you know what!?
He doesn't need that. He does not feel superior as to deserve special treatment. He wants an iPhone he stands in line like anyone else.
Yes, he could have called Tim Cook, or got an assistant to buy for him (he certainly can afford one), but no.
Really? A 45 min commute is not on my list of "absolute hell"
Of course it depends if it's by car, or bus/train etc
I would absolutely commute 45 minutes for a good job. It may be tiring, yes, but it's not very far from the average (and even better than the average) for most major cities
Having said that, working close to home is very pleasant.

Most likely it wasn't the processor that 'passed away'
Notebooks have several areas where excess heat can cause damage (especially on most cheap laptops today). At 72F? Not the processor
It's most likely a power source failure, or another area getting too hot and melting the solder
Don't worry, they'll post the MPAA and RIAA sites on their homepage
It also requires you to upload a massive amount of art data and downloading a movie in full resolution, with minimum compression.
Or you can 'physically' send them (I guess Amazon has a service like that)
Exactly
Also, margins are not only because of the model, but variances between materials, material fatigue with time, etc
You can't disprove the existence of something which is not sure to exist.
(Of course, you can't turn off a light that's already off, but that's too obvious)
So saying the LHC cannot disprove the HB is like saying no one can disprove Unicorns
nice try
Erm... no
Actually, the LHC can't prove the existence of the Higgs Boson
They can show overwhelming evidence for it, up to the point the Higgs Boson is as accepted as the electron for instance
But until then, you can't "disprove" a thing that has the best evidence for existing @ 3 sigma...
Yeah, I mean, you cannot pay for a photo with Richard Stallman for $3.41
And the worse thing is, there isn't a shortage of new candidates for this list
"much harder to refute" how about no
- Neutrinos through Interstellar medium vs. neutrinos through "planet earth" (almost the same thing to neutrinos, sure, still, almost)
- Neutrino interactions with interstellar medium
- Neutrino oscillations
- Neutrino generation process in a supernova event How do we know the level of neutrino generation didn't begin to raise 4 years before it went supernova? Far fetched yes, impossible, no.
Yes, the stock is clearly increasing over time...

No, my CPU doesn't stress out while playing an MP3 using any program while PulseAudio is disabled

Also, JACK helps with latency, instead of totally screwing it up like PA

This
And especially true regarding Ubuntu lately

Well, since the 'neutrino' name is (kind of) Italian...

Yes

Yes

Good for him.
I agree with you, but I guess there's more to it than only time.
A 45 minute on a calm road isn't very stressful.
I once had a "choice", a 30 min "pedal to the metal" commute or a 1h through city traffic. City traffic was usually less stressful
Really? A 45 min commute is not on my list of "absolute hell"
Of course it depends if it's by car, or bus/train etc
