I don't think that's the case. Here's your pipeline:

App->CoreAudio->HWSoundCard->Speakers(or amplifier)

By using floats in the sound API you don't reduce the bit depth on the first step but you still do on the next two steps. Imagine a scenario where you want to set the volume at half the maximum volume. Your two options are:

1) You set the app to 50%. Core Audio handles that as floats but still has to program the hardware to only output half volume, so if the HW itself doesn't take floats the bit depth is halved. And the HW will always have to output half the voltage so the "voltage depth" of the third step is always halved.

2) You set the speakers to 50%. All the pipeline functions at 100% bit/voltage depth all the way to the speakers/amplifier. Only then, at the final amplification stage, does the signal not get boosted to 100% and only to 50%.

How much this affects real world performance beats me...
That's not the problem being solved by Markdown. You don't want to be serving HTML written by users.
Because you can have more than one application with sound output. I like listening to music while I play games; I set the music to 80%, and I set the game to 15-20% volume. This cannot be implemented in one single volume control.

£51 for 5GB of data is expensive. I'm in the UK and on t-mobile I pay £17 per month for unlimited data (not 4G though), all calls and all texts (well there are limits, but for my moderate/heavy usage it's as good as unlimited) and those calls include some international.

And until this year, it also included a free handset, last one 20 months ago was a desire HD. So £10/GB does sound expensive.
Really expensive by UK standards. Of course the US have much higher prices along the line due to their uncompetitive mobile market.

Here is the answer from "the writer" :)

Interesting question I think, seriously.
Do I search for validation online? I don't think so, I have enough of it around me, without having to turn to the web :).
What about tip (experience, hack, call it the way you want) sharing?
I see a lot of great posts written by really cool people around here; maybe is it also a way to try to give something back (or in your words, probably try to fit in the group in search for the reassuring feeling of being part of it ;)). This is (IMHO) the most probable reason.

I use all those tools for a long time, and discuss about it with my friends regularly. I think it is good for yourself to try to be good at what you do. Writing such articles and sharing it in the open is a way to find people having the same interests as me that I would never have found otherwise.
Hopefully, the post will lead to interesting interactions (exactly what I am doing right now :).
Can I call that peer-validation? Maybe, but not in the exact way in understood it in your comment :).

As a non native English speaker, I might be wrong but I felt like condescension in your comment. But this is probably my french nature speaking :p
Right, but this doesn't guarantee beta access, nor does it confirm anything we didn't already know. I'm not trying to be prickly, I just don't see the point of this submission as it stands.

What's missing in Go/Gorilla for web dev?

Well, it covers:

Serving (great built-in server for net/http)

Routing

Sessions

Context

--

It's missing:

Authorisation

Authentication

Parameter Validation/Checking

Asset management

Migrations

Cleaner templating (I prefer mustache to the built-in go templates)

HTML Helpers/View Helpers

Form Helpers

ORM or other persistence helpers (controversial I know)

Possibly scaffolding would be nice too and a suggested project structure to encourage sharing

--

So there are a few things which you'd generally expect in a web framework which aren't there yet. Of course some of the above list is subject to debate, some is available in revel, some it not everyone would agree is even necessary, but most other platforms in other languages have a bit more to help you, even if they are minimalist. Even just having an agreed-upon set of conventions and structure for web projects (a la rails), speeds up comprehension when looking at any large code-base.

I'm quite confident Go will get there, and having tried it out am really impressed with the language and the culture, but it would be disingenuous to suggest it has everything you'd need to produce large web apps currently - at present you have to write your own code for quite a lot of the above.
Google App Engine Down?
Heh, I came here with the exact same sentence already in the clipboard.

I agree ... As far as I know, "browsing the web" with modern expectations is Turing-complete, i.e. it needs a device able to execute general purpose programming.

I really wonder what they think they can do to somehow simplify this using a "fixed-function" design. Whatever that is, in this context.

If you have some form of aphasia it may be hard for you to find the words you need to say, but you can still choose and reason about what you're thinking about. You're able to conceptualise, you just can't put the right words to the right concepts. It's definitely far more than a feeling or intuition.
I'm not sure it's correct to say that the consoles haven't evolved. The fixed hardware hasn't changed since 2005/2006, but the software has been very nimble, especially on the 360, which has had 2-3 very different iterations of its OS as it transitioned from games console to full multimedia device.

This console generation has been unusually long and one of the reasons is that the console makers got so much right this time that its taken a long time for the consoles to feel dated.

How to Create Tin-Can Lanterns
This may be true for the intermediate steps but but the last step is still a DAC changing integers to analog voltage. If you are attenuating the signal before that point you are still losing bit-depth (even if, by the magic of floating point numbers you are reducing the aliasing and other artifacts).
Agreed. Release early and often is well known and accepted in software engineering... yet some stores do their best to make that impossible.
I like the idea of avoiding distractions and avoiding the browser. When working on personal projects I tried several times not to turn on the wifi or to work directly in the terminal without running a Desktop application, but at some point I have to use the browser again to look up for some docs or install something.

No, the second statement says it was posted at 4:34 in English, and three hours later in Chinese (about 7:30), half an hour after it had been blocked in both versions.
The OP was saying that the original English article was posted 3 hours before the Chinese version, giving the Chinese government time to block NYT before the Chinese language version was published.

All good points, CMS ux can get fiddly, front end editing can help, but that's a rabbit hole i'm not keen on,

I think I've managed to keep things reasonably straightforward (e.g. for these oddball pages all the fields are on a single page in the admin, with a nicely segmented form), but as ever there is a lot of room for improvement, and I do concede a time for doing things by hand occasionally :)
I'm impressed that they made it as far as they have. $612k puts them in the top tier of all Kickstarter projects, but unfortunately they look to have set their goal too high. Maybe they can pull a Clang and raise a ton of money in the last 24 hours, but I'd be surprised to see that happen. Here's hoping I'm wrong.
I have several concerns about the original article, but if the point of this guest post on Newport's blog is "look, I was able to grind through the MIT requirements in a year with reasonable success" it is not particularly damning that all the person achieved is a beginner's knowledge in several courses. Hopefully readers realize that this is not necessarily such a wonderful achievement while simultaneously respecting the effort made.

My bigger concern is that the overt focus on "time-compressed" learning is that it will devolve to pure hucksterism with no attempt to move beyond anecdote to real research and thought as to how teaching (either by self-directed methods or to students in a traditional way) can be improved. People seem so interested in short-cuts. I personally want to an "efficient studier," but what I mostly mean is that I do not want to waste time using bad learning methods or materials.

We do know that improvements in the learning process are out there - better books, spaced repetition for recall, better guidance and opportunity for early learners than they get in schools in subject-specific areas, etc.

These types of posts along with my reading of immersive learning experiences (like your own math programs, dual language programs, "programming school" opportunities) has me thinking about the innate value that immersion offers to the learner.

Would linear algebra learners be better off to spend 4 weeks focused on only that subject with a professor/mentor, a textbook, and deliberate practice than a single semester of normal lecture instruction?
With 31 hours to go. If they don't raise $138,000 in 31 hours they get squat.

Indeed. Usually I perceive the motives are to increase the author's employability attractiveness, promote their business, or build status within their community. Some productivity posts fall into those categories too I believe, but usually to me the validation model is a better fit.

Here's sort of the flipside of that anecdote:

Me and a group at my school are currently developing a mobile communication app for elderly for a interaction design-course, and we are in close cooperation with two local elderly homes for testing and feedback. During the initial phase we didn't settle on whether we should develop for iOS or Android but focused primarily on how the interaction should work. But after a while the local leader/our contact insisted that we develop for the iPad since the elderly at both homes had been to a iPad-workshop.

2 weeks later she tells us that she's bought two iPads for us that we could use for testing. When we get there, with our low-fi PowerPoint-prototype, it turns out that she's bought two Galaxy Tab's!
I should summarize the post with 'computing is not green' or even more 'human interactions' are not green. Flexibility is not green. Look at brains: they are resource hogs. But.
They only have 31 hours left to raise the rest of the money. Considering they fact that they took several weeks to reach this point it seems unlikely that they will hit the goal, and therefore they will not secure any of the pledged funds.
The "best" answer seems wrong or at best misleading -- I would be very very surprised if the user-visible OS master volume control, which typically controls the sound card directly, was not directly controlling op-amp gain at some later stage of the sound card.

Assuming this is true, the correct option would be to maximize any application volumes (e.g. YouTube), to maximize master volume to a level just below the sound clips (distorts) at the amplifier input, and to reduce the amplifier's pre-gain (if it has any) so the master volume control has a reasonable range.

This method will minimize the three (not just one) culprits of poor computer audio quality: quantization at the application layer, electronic interference over the physical connection, and clipping at the pre-amp.
Consoles and PCs take turns being "dead".

If the PC is "dead" it means consoles are at their top of performance. If consoles are "dead" it means the current console generation is getting old and in a few years new consoles will appear, their hardware artificially low priced because manufacturers expect to make more money from licensing.
This seems like it should be a simple straightforward issue, but I still have problems with ocassionally getting clipped audio (or some kind of distortion, I'm no audio expert) on Windows 7 with Realtek's "HD Audio" chipset/driver.

As far as I can tell, I rarely if ever have this problem with the same hardware in Linux with PulseAudio (though I can intentionally cause it using alsamixer by pushing "Master" to 100%) and didn't have this problem in the past on Windows with Creative Labs soundblaster cards.
Why Average VC Returns Don’t Really Matter
Note that you could install GRUB on all the drives in RAID when in a clean state, making them all bootable (avoiding the "non-bootable yet okay array member" issue).
There is nothing inherently wrong with sharing an opinion. I just disagree with the opinion and feel that said opinion reeks of entitlement.

How does the prize not have value? If you won, you could trade/sell/exchange the prize for something else... so, wouldn't you agree that means it has value? If you want to ignore this paragraph, I'm fine with that... as having a discussion on the definition of value probably has little value.
I'm happy to see it get more attention, but to say it is "dying" is a bit hyperbolic. Sure, the Kickstarter campaign seems like it's unlikely to meet its target.

But from the sounds of it I don't think the company behind it will just give up if that happens. I know for my part if they put up another campaign, preferably with a longer lead time, elsewhere and/or take pre-orders, I'll commit again and I'm sure a lot of the other people who signed up will too.

I think it was unfortunate that they didn't release all the material they've released in the last few days right at the beginning of the campaign, though - they'd likely have done better. They've also clearly had a hard time explaining to people what it's for, which is a pity. I don't think the 16 core version by itself is all that interesting from a performance point of view, but I'm interested in the architecture in the hope that they manage to pull of the 64 core version and larger.

EDIT: It's added $20k in the hour since I wrote this - happily it looks like it's got a good chance to succeed.
I didn't have quite as bad an experience submitting my app (http://codecube.net/2012/09/introducing-viewer-for-khan-acad...) to the w8 store. But it did fail the first time and I was quite annoyed at the reason. It failed for requirement 4.1.1:

"If your app has the technical ability to transmit any user's personal information, you must maintain a privacy policy. You must provide access to your privacy policy in the Description page of your app, as well as in the app’s settings as displayed in the Windows Settings charm."

Now, my app is open source, and doesn't collect any user information whatsoever. And not only that, but the app's meta data during submission has an optional field for a privacy policy URL.

So I just ginned up a quick privacy policy that says we don't capture any personal info (http://codecube.net/khanacademy/privacy/), added it to the settings charm, and resubmitted. It passed.

But it was annoying.
Why Doctors Withheld a Debilitating Diagnosis
Google AppEngine down ??
> do your studies and use those massive amounts of free time to socialize and create new things.

I never had massive amounts of free time at college. Maintaining a 3.9 in Computer Science without having the same amount of raw talent (and previous experience) as your peers is really hard, so I had to work my ass off. My schedule was close to 16 hours per day, 7 days per week (including classes). It was "Hell Week" for the ~4 years I was there. I worried my family and friends. It was unhealthy.

Trying to keep up with, frankly, __smarter__ (and, most likely, more intelligent) peers was a real challenge. I tried "Studying Smarter, not Harder", but lacked the skills from K-12 education to do so. Attending classes on "How to Study" and the like really didn't help and, no matter what I tried, I always fell back into investing more time as a solution.

I lacked the bio-hardware (read: brains) to go into Computer Science. I did it anyway. Don't forget about people like me!

> Life is good at this time

No, it wasn't. Not for me.

> Those of us with jobs and families snicker at college students who claim to be "so busy".

I don't. I have more free time now that I'm married and working (a stable and well-paying job, thankfully).
Alsamixer for Linux makes this much easier, as it shows the actual level in dB (at least for any sound card I've ever owned). For example, 0dB (maximum volume without clipping) is at ~74/100 on one of my cards, not 100/100.

Talking with Amazon to make a special deal for hosting that data would not be a "just." The major point remains - archive.org knows how to host and provide large files, so the issue must be some other factor. I think they want to know if it's worthwhile to do so.
jbbeats had an interesting point before he fell into personal attacks so I will express it here with less vitriol.

Jailbreaking is explicitly not an intended use of the product, and a manufacturer shouldn't be expected to provide any support whatsoever to something which the explicitly do not intend as a use. There may be all sorts of unintended consequences to jailbreaking and its unfair to expect a manufacturer to have the resources to think of every possible use case.

To take a ridiculous example (without copying jbbeats) if you choose to cut your hair with a lawnmower, you should not be able to complain that the lawnmower manufacturer didn't make it easier for you to swap out the blades for ones that barbers use instead of the cutting grass variety. That I think would be an unreasonable burden to put on the manufacturer.

There also may be unintended consequences in the basic operations of the machine if it is used in a different use case. For example, maybe hair grease could acccumulate overtime to make the lawnmower dangerous overtime. Perhaps a rubber guard would prevent this. Now the lawnmower manufacturer is having to support optional rubber guards for each range of lawnmowers for those few people intending to cut their hair with it.

While I share your desire to make jailbreaking easier, I don't think a law is the right way to do this.

Massachusetts fines Citigroup $2m over Facebook IPO
Just think about the original concept for Loopt: constant location sharing to your friends. It's pretty difficult to quantify how much of an increase in sharing that is over a status or two a day, but it's probably much more than 1000x any way you cut it.

It's understandable that people think Zuck is saying people will share 1000x more on Facebook using Facebook the way Facebook currently exists, but that's not it at all.
