> When possible go for XLR on the last mile to the speakers (good neutral studio speakers) to cancel out distortion from external electromagnetic pulses.

A couple minor corrections: XLR is just a connector, the equipment has to be balanced and there's plenty of equipment on the market with XLR jacks but unbalanced signals. Second, electromagnetic interference does not cause distortion, but it does cause noise.

Balanced signals are far from a magic bullet. It is basically a tool for solving a couple specific problems: interference and ground loops (NOT distortion). In a typical home setup, interference and ground loops will not be a problem, because we're just talking about plugging a CD into a stereo that's a few inches away, and they're both plugged into the same power strip. Balanced cables are more helpful if you have audio equipment plugged into different mains circuits, or drawing lots of current, or transmitting signals over long distances (more than 10 meters). For your home stereo, regular RCA cables are sufficient.

> this doesn't make a difference for compressed pop music but for uncompressed recordings of live performances with analog instruments or natural soundscapes it does.

I'm sorry, but this is just ridiculous. The noise floor of 16-bit PCM is -96 dB. Your living room, if it is very quiet, has an ambient noise level of 30 dB SPL. Or you could suppose that you spent money soundproofing your rooms, and you live out in the country, and it's as quiet as a professional recording studio, at 20 dB SPL. Now, turn up the CD player until the noise floor is audible. What happens when you play music? It will be at 110 dB SPL, which is the same sound level as sitting next to a chainsaw.

Now, the benefit of 24-bit audio is that you can play music louder than a chainsaw (> 110 dB SPL) and still have parts of the music that are quieter than a whisper (< 20 dB SPL). Even without compression, it is rare for actual live performances to have that kind of dynamic range. Pianos, for example, are simply not physically capable of it, with typical microphone technique.

Trade protectionism is a completely different issue from immigration and I don't see how it's relevant here.

That being said, you definitely can have entry into those markets while putting up barriers of your own, there are many historical examples when this was successfully done, e.g. 19th century was probably a peak of such practices. The only question is if you should, and if it's worthwhile right now - you can go to any place in USA and you'll see lots of things that are manufactured in Mexico.

And the relationship is exactly the opposite of what is implied by your comment - a large wage disparity means that the developing markets aren't as "useful" as is their cheap labor; if wages would become more equal, then this change would generally reduce the outsourcing of labor to the third world and increase the export of goods made in USA to India or Mexico.

This is epic, I don't think Ionic has publicized these docs for their upcoming platform yet.
You start by mentioning everyone wanting to start a startup, then switch to saying how it's better to be an early employee at a start up.

Being the founder of a start up acquired by Google in 3-5 years may be better than working there for those years, however that is not necessarily the case for being an employee at one. Other comments in this thread point to equity in startups often being too low, so I wont repeat the same stuff.

A 2-way 1-ary cuckoo hash was going to be my answer as well. As you say, you want to always check both table indexes rather than waiting to see if you need to, but in almost all cases it's faster to do this anyway.

Since I think he only wants to check for equality, a constant time comparison of 160-bit values should be easy too. If you have a modern x86 machine with SSE4.1, the easiest might be to use _mm_cmpeq_epi64(vpcmpeqq), _mm_and_si128(pand), and _mm_testz_si128(ptest). With 256-bit vectors, it gets even simpler. But any scalar solution should be fine too as long as you can convince the compiler to do what you want.
The intriguing point to me that I haven't seen addressed on any reporting of the announcement is this:

Is the plan to put humans on the surface and then bring them back home? How do they intend to land and get back off of the planet?

(Forgive me if they addressed this in the video; I haven't had time to watch it yet.)
The police state is unassailable
The issue is that if the public is unhappy with the police force there is no way for them to vote in a re-organization.

However in the private sector this happens all the time; either forcing one company to re-organize or a re-organization happens by a company going out of business and getting replaced with another one.

Voting for a politician (especially when you are stuck with two political parties) hardly constitutes voting for a re-organization.

Maybe there is a way to create competition in some way shape or form by having several different police forces (still government sponsored) that compete for your vote or maybe something else. But there definitely is a problem that there is almost no way to properly restructure a bloated government organization when it is underperforming, and somehow that should be addressed.
Yes it does.

I don't see how either of these papers solidly refute "because Nyquist" in the context of the article and sample rates applied to audio signals. They're both worth considering, though.

The first[1], the more theoretical of the two, is focused on digital communications where a Nyquist rate derived from the signal rate isn't enough to recover the signal function. The numerical examples given highlight recovering a sine wave from two, three, and six samples. The millions of samples in a single song might as well be infinite compared to these.

The second paper is much more practical and gives a number of real-world examples where naively applying Nyquist causes problems. The first, cutoff filters at half Nyquist to avoid aliasing, plauged many early CD players and other digital audio equipment. The second example is great as well, showing how understanding the signal being measured is important. The third example doesn't really apply to the subject at hand but is a good example of using aliasing for good. The fourth and fifth address the effect filters have on the signal. The sixth example refers to time response in control systems and minimizing phase delay to avoid oscillations.

I'm very sad to hear this.

In the very early days of Rails Ezra was one of the most helpful people on the IRC channel. When he mentioned that he worked only a few hundred miles away I helped hire him at a small software outfit in Spokane, WA and worked closely with him for over a year.

From there he left to co-found EngineYard.

He did so much for the Ruby community and will sorely missed.

I'm glad I had a chance to know him.
There's a fair amount of pros that utilize Audeze and HiFiMan gear as well. Planar magnetics are popular.

Erik Larson is pretty vocal about his use of LCD-2s for mastering. Which... Honestly, I'm not generally a fan of his work, so it's not necessarily a ringing endorsement.

Also kind of surprised at your lack of mention of AKGs - they're another very popular brand for studio work.
I'll believe it when I see it. This must be about the 20th such announcement from NASA, and the other 19 have sunk into the bureaucratic morass without a trace. I see no reason to think this time is different, particularly in light of the mountain of unfunded liabilities that are going to keep budgets tight for decades.
The article reports that some schools are having to give large tuition discounts to attract a decent class, and the writer predicts closures similar to dental schools in the 80s. The most interesting tidbit was that "the biggest application declines have occurred among students who scored in the middle-to-high range on the LSAT." Confirms my general feeling about people who borrow heavily and go despite the overwhelming evidence that it's a bad idea outside of the top schools.
I think your pricing is honestly too low. First, nobody here is complaining that your pricing is too high. Second, when evaluating pricing, it's useful to ask "what serious customer would pay $5/mo but not $15 or $25 if we are providing real value to them?"

I run Cronitor.io, a monitoring service for scheduled jobs. In our case, we have about as many users on our mid-priced plan as we do on our entry level plan. The message our subscribers send us is: we're not shopping on price, your fees are reasonable, just keep building your product.
Question for Tyler (or anyone who signs contracts with their customers):

What's the minimum deal size that you'd want to have a contract with a customer? If you're a $50/month SaaS, it probably doesn't make sense, but I could see the benefits as you approach $50k+ / year deals.

Is the primary benefit to lock in the customer (ie. annual commitment)?
Very cool project. I love people, data, and beverages -- this project touches on all three!
'If that's deemed too heavyweight, you can just add "delay" as a random amount of computation overhead (say a loop that does nothing but does not get optimized away).'

If the delay here is not meant to be random, what is the "that" being contrasted against? I understood "that" to be what you say, which would imply this is something different.

> if you are devops (whatever the sysadmin/developer ration), and don't know how to use AWS (or other cloud providers), your job prospects are going to look pretty grim (non-existent) 10 years out.

I personally think that people who can use AWS are pretty common, and using AWS is only getting easier. If you know how to work with actual, physical hardware, on the other hand (which most people even today don't seem to know how to do), then you're going to be in a much better position, skill-wise, than someone who only knows AWS (which is many people).

I've seen a neurologist who my GP thought highly of, but it quickly turned into probably the worst doctor's visit I ever had.

About ten minutes into the exam he told me that it was either depression, or sleep apnea, and that I was just looking for a way to get out of working.

I'll admit that the Part of it was my fault -- I was beyond exhaustion and not exactly on my best behavior. But I also had seen maybe eight different doctors before then, and, other than sleep apnea, had been misdiagnosed and mistreated for several things already. My GP didn't seem to believe that there was a real problem, and I was just falling apart physically, financially, and emotionally.

That's about where I gave up hope of getting useful medical help, and decided that I was just going to tough this thing out, and if it kills me then that's just how it goes sometimes... Not a smart choice, but that's where I was at the time.

Any way, that was then, this is now. Writing these posts has gotten me to think about how long this has been going on, and, now that I'm more clear-headed, it's time to start seeing doctors again and see if I can get this fixed.

I just read NDT's Death By Black Hole [0] in which he mentions some cities like New York waste millions of dollars a year on the energy that sends light skyward. So the incentive is there, it's probably they have failed to be long term thinking enough to eat the upfront installation costs until the the reduced overhead pays off 5 years later or w/e.

Neither is more 'right' than the other, only that it's pointless to criticize people who are long-dead. It's important for people to realize that European immigrants did (and do) largely the same thing as other immigrants that people often criticize for not learning English, but we can't change the past.

I don't believe these feelings are necessarily entirely rooted in racism, as I've heard plenty of people in Chicago complain about Polish immigrants unwillingness to speak English. I think it's more likely the feelings are a mix of racism, classism and additionally a sense of pride in American culture.
This makes me feel marginally better about dropping out from law school (correspondence version - the bottom of the barrel) after attending a large conference and realizing just how awful the odds were. It didn't cost me too much financially but I still feel depressed about it.

Fewer and fewer institutions have tenured professorships these days, for three reasons I can think of:

- The pension plans that typically go with long-term employment like tenured professorships are expensive.

- Tenure gives professors a protected position and more political power, which is threatening to administrators.

- Exactly the reason this article addresses: institutions want to light a fire under people to force them to optimize for the amount of grant money they pull in, rather than for scientific achievement, or (gasp) quality of life.

The context of the story suggests that he was not one of the lucky ones, although it is possible that he was, and the university was going to fire him on grounds of some breach of contract or with the argument that he was otherwise breaching his duties as a professor by failing to bring in money.

If your goal is to do X in space, then mining asteroids might be a valid means to help you do X, but not an end goal by itself.

Most missions don't need a large supply of water, hydrogen and oxygen located in a random orbit around the sun. If you need them at Mars or Moon, then likely it's easier to find the supplies there instead of spending a large supply of fuel in order to move a large supply of stuff to that orbit.

If we'd need stuff at LEO, it might be that flying to an asteroid (generally far, far away from LEO) and then pushing it to LEO is more efficient than pushing it up from Earth, but it's not so clear.

In any case, this scenario of mining asteroids is very different, I somehow think that the grandparent poster meant mining stuff for us back at Earth.
the difference is, if a private company generates waste, its shareholders pay and competitors benefit. If government generates waste, everybody pays and nobody benefits
>The best definition of audiophile I've heard is somebody who listens to equipment, rather than music.

Audiophiles are an easy target. There are a lot that do stupid shit like buy $5000 power cables, expensive risers to lift cables off the ground, etc. A lot are pretentious, even if they're not insane or dumb.

But that's a rather inflammatory, and in my opinion, unfair position to take. I would probably be considered an audiophile - I have put quite a bit of money into audio equipment. But I love music. I listen to it basically constantly. It's one of my primary sources of entertainment - and I don't just mean 'I have music on when I do other shit.'

Each week I spend probably 20 hours doing nothing but relaxing with a bit to drink and some music on. Not reading, not surfing the net, not doing anything but closing my eyes and enjoying the sound. I'm listening to the music.

At times, yes, when I have been testing out new equipment before deciding if I want to buy it I go through and I do blind ABX tests with level matching. In this case, yes, I am listening to equipment. But this is a very minor portion of my total listening time.

I know you're probably not being totally serious with the post, but I do think it's a bit unfair towards those of us that love music, but also have invested time and money into getting a setup that sounds better for increased enjoyment.
"Completely undefined" is a good thing, because it's a strict line between good and bad (good and evil?). So, now that you know all integer overflows are bad, you can:

* dynamically test your program with ubsan to be sure they really don't happen, and then

* let your compiler optimize with the knowledge that integers won't overflow.

This last one eliminates maybe half the possible execution paths it can see, and loop structure optimizations practically don't work without it.

On the other hand, unsigned overflows? Some of those are bad, but some are fine, right? How will an analyzer know which is which?

Some notable libraries like C++ STL want you to write loops with unsigned math (size_t iterations), but those people invented C++, so why would you trust them with anything else?
In case some people skipped the bottom:

> Vibration is one of the factors that would make the same audio CD, read with the same CD player, produce different digital signals some of the time or even every time.

Err, no.

That makes sense when you have an analog version of the audio picked up by an analog transducer (i.e. a vinyl record) but makes no sense with an isochronous stream of quantized samples.

I suppose a vibration could cause a small phase shift in when the sample physically appears under the LED, but but since the D->A conversion is clocked by a PLL it is irrelevant.

If you have extreme warping or shaking (e.g fling your discman onto the floor or stick your finger on the disk while it's spinning) then a sample might not appear at all, but that's something different than you are talking about.

I suppose it's theoretically possible that some extreme warping or vibration could cause a bit flip, but that's what the ECC is for.
If it didn't cost you too much financially, chin up. Those are the best kind of life lessons.
I would expect that the resulting quality of not-retracted and proven-by-time papers in Nature is a lot higher than in any other journal. Simply because of higher exposure, more attempts to reproduce or use studies and more scrutiny.
The first 20 minutes of this, with Tyler, are the best thing I've seen in this lecture series so far. And, in particular, this slide:

https://www.dropbox.com/s/axgpmehewplt7hs/Screenshot%202014-...

... has to be a contender for the most valuable single slide they've shown in the course. It is dense in an almost Tufte-sort of way:

* It exhorts you to diligently follow up with prospects

* It gives you an idea of how much work it takes to convert a prospect

* It gives you permission to follow up when prospects go dead(!)

* It reassures you that this is what actual, real, live prospects really look like

* It tells you what you're in for with real prospects and so shows instead of simply telling why you need to get good at lead qualification.

So great. Could go on and on. There should be, like, an "email (no response)" tattoo we all get. This was outstanding. Thanks for publishing it.

The "talking to investors" stuff is good too. I liked Michael Seibel's One Simple Trick for arranging first meetings with investors to create competition. And Dalton and Qasar's mock investor pitch was funny --- but if they wanted full verisimilitude, they'd have ended the worst conceivable pitch with the investor saying "We're excited! We definitely want to invest!"
Honestly I forgot about AKG. They're pretty good, although I don't see them a lot in commercial environments (~15 year window).
