It's a problem with Rails because Rails provided the update facility that takes user data and told people "if you use this, you can build a blog in 15 minutes." If you're turning user data into SQL, at least you're the one who wrote the code. Your database didn't come with a parse POST and update table function.
It can also do "satellites above": http://www.wolframalpha.com/input/?i=sattelites+above Make sure you enable interactivity (if you have Pro) on that last graph, it's pretty amazing.
Great stuff! And most are already in my TODO list indeed...
The next weekend I'll hack on it a lot again to bring a few of this features.

But I would add another one:

e) Ability to write some kind of assembler or other low-level stuff interleaved with Lua, so that's possible to also do as-fast-as-ASM computations if needed.

I guess this should be a layer translating something like Z80 assembler into x86 code. You call Lua with a string containing the program, it gets translated, and executed. I guess it should not be entirely impossible to provide something that also compiles to something safe (that can't crash the Load81).

Thanks for the suggestions!
dislike the drop release to fire, but everything else is AMA-ZING!
To me it is one thing to be noticed ('get their name out there') for remarkable products/services, that took either time, effort, genius or a combination.

It is a complete separate thing when you either haven't produced anything, or have produced, but it is far from remarkable, and you are being noticed by running around screaming.

It is the latter that gets tiresome and old. Not to mention the former is so much more honerable.
I am following exactly what this guy says, but it took me a long time, over three years, to finally settle on whats important for this kind of career. I revisited C so that I can keep up with git code and learn from it; I bought a Rails book,and I am trying, although very slowly, to do anything that comes to my mind in Ruby. This is not about Rails, its about a healthy shortcut. I was not lucky enough to read something like this sooner. This is excellent advice, and I commend him for saying it.
I could swear I had read a similar rant of yours somewhere before, but could not find it.

Anyway, I do not disagree with you. What I was trying to convey was not so much the quality of current intrinsic code, but the progress that has been made in the last ~5 years in this respect. I remember writing some intrinsic code that became a series of useless stores and loads all over the place. When that is your baseline, current tech is impressive, modulo the issues you've quite correctly pointed out.

Google: Introducing a new local search experience across your devices
10 Idiotic Newspaper Headlines
> Google and Yahoo have been preaching for years that even fractions of a second of page load time have a big impact on how likely users are to give up and go somewhere else

Well of course they worry about it. I can ditch Google and go to Yahoo, DDG, Bing, hell Lycos might still be around, if the Google homepage takes too long to load. Obviously same for Yahoo. Neither of them produce or host the content (search, news) that you're going there for.

That's not quite the same situation as Twitter, GMail, Facebook and whatnot. Where else are you going to go? Your mail is in GMail, or your friends tweet is on Twiter, their wall is on Facebook and they are only there. The "instant load or I'm out of here" doesn't apply so much to them. It really only affects new users who have no other attachment to the service.

I doubt it's much of a problem for Twitter.
"There is probably a minute number of cases where someone wants mass assignment changes to include the parent's id of that record"

So it sounds like you aren't using mass assignment to change parent ids either. Most people don't. Most people use mass assignment to change the attributes of an object, not that objects association to a parent.
I am amazed that anyone still works there.

Are facebook and google continually inundated with Yahoo ex-pat applications?

Anyone at Yahoo on HN that could provide a day-in-the-life?

Or anyone from Yahoo have any stories of trying to find work elsewhere?

I'm not a dev, but since this is an open post, I thought I might ask some questions:

I'm in the Midwest, at a shipping hub, so I know you have a huge market ripe for disruption, but how did you decide to make the product? A transition from an agency to logistics isn't a common one, so you probably have a good story.

Also, do you have any product traction? I know trucking has firms ranging from single drivers to large enterprises, but even if you have a few small groups lined up, it means a great deal to a potential applicant.

I see this happen every single day and do my best to upvote the comments but to no avail. It's the No Me Too Posts Policy taken to the extreme and it alienates people from one another.
I am curious to see if this gets downvoted, flagged or just simply what other people in the community think!

Take a detour through FreeBasic where there are no limits (you'll even understand pointers, data types and objects), then go back to Python. Challenge yourself and have fun. For example try to write a program that stores a key-value pair and that enables you to retrieve information through sockets or can even be compiled to a library.

This is a really convincing article that makes me want to set up a double blind test for myself with my own equipment.

In my own tests I believed that I couldn't tell the difference between 16/44 and 24/96 on high quality loudspeakers, but I could with high quality headphones. The studies cited all seem to use loud speakers in testing.

Also worth noting, the article states that obtaining 24/96 source material sometimes means you get better mastered material, which still sounds better after down-sampling back to 16/44.

Huh, I think people truly advocating 192 as a distribution format will be few and far in between, a really good and cheaper sampling system can be put together at 96. Still, a lot of things in this article perplex me.

Human hearing is limited to 20k because frequencies higher than that are perceived as painful? Dont agree with that one.

24 bit doesn't offer any advantages to sound quality? Sheesh.

And the crux of the argument is intermodulation distortion increases when you try to represent more frequencies? Isn't that an argument for a faster power amp?
Thanks for sharing. Our take:

- Right now we have an application-wide setting that says, "Add X minutes to my travel time." We're hoping people will use that to accommodate the fact that they have to walk to their car, find parking, etc. Eventually we'll make this configurable for each event.

- Yeah, traffic estimates aren't 100% accurate, but they're better than crossing your fingers and hopping in the car. :)

"People often tell me to make stuff, and when I do, I follow tutorials and simply copy what I'm told to write to move on."

That's not making stuff. You have to think about it yourself. Programming is not memorising syntax and copying other people. Programming is thinking about solving problems in a way suited to the tools you have. That is what you need to work on.
There's a lot of scientific-sounded content in this, but unfortunately most of it couldn't be further from the truth. I'm an ex-audio engineer and studied digital and analog audio engineering; this has been debated to death over the last 15 years.

Digitally recording a triangle is the best example of why 48kHz is very limiting. The distinct sound of the triangle constitutes of a high fundamental frequency, ballpark 5kHz and of many very high-pitch harmonics. Most of these harmonics are above 20kHz. The harmonics are what makes it sound like a triangle, not the frequencies below 20kHz. This is why the triangle is one of the hardest instruments to digitally record. It always sounds like crap.

In theory, it's true that the human hear can't hear above ~18kHz, but it can hear the influence of the very high pitch harmonics on a lower frequency.

It depends on how comfortable you are with getting your knowledge from college textbooks (which can be rather math-heavy) rather than online tutorials.

Hey cmer, thanks for posting

I don't think I understand quite what you're saying and wondered if you could explain more. You and the article both say that humans can't hear above about 20kHz. If there are higher frequencies that create a harmonic at a lower frequency (e.g. a 33kHz harmonic that produces a sound at 16.5kHz) then surely that lower harmonic (16.5kHz in this case) will be recorded by the original recording equipment assuming it is recording at a frequency at least twice that of the highest audible frequency (let's say that this would be 48kHz, although there might be other DAC-related reasons to go higher).

I'm possibly being very daft here!

He raises a lot of valid points. However...

192 kHz is clearly overkill for listening. Not so for further editing of the data.

Same goes for 16/24 bit, however, the difference between 16 and 24 bit is actually audible.

44100 is not a bad sampling rate, but it necessitates very sharp aliasing filters, which are audibly bad. A bit more headroom is well needed there.

That bit about intermodulation distortion is complete bogus. He talks about problems when resampling high-fs audio data. However, you would never do that. You would digitally process 192kHz all the way. Only your loudspeakers or ears would introduce a high-pass filter, and a rather bening (flat) one at that. There is certainly no aliasing going on there unless you resample (wrongly). Intermodulation distortion is not the fault of the sample rate.

I mayored in hearing technology. Calling 192/24 worse than 44.1/16 is total BS. How useful it is is a different debate.
Thanks. Number theory sounds very interesting. I think I am going to pick up a book or a website on it ... really want to look into it.

My Top 5 SQL Server 2012 Features by Aaron Bertrand, Guest Blogger
State of desktop Linux
So. Been dabbling with Linux on and off since the 90s. Even more so during the last couple of years. Last year I moved my mysql insance from my ubuntu server to Windows. This evening I decided to try Linux Mint KDE, Ubuntu 12.04 beta1 and eventually wound up running Linux Mint Debian Edition. It is still not... windows. Don't make this a windows vs Linux flame war. We all know that for ordinary office tasks, windows beats Linux hands down. The reason for trying Linux on the desktop again was an itch to see how far Wayland has come. Ended up quite frustrated with my experiences tonight. I have high hopes for Wayland. It is one of the biggest opportunities for desktop Linux in years.</rant>

I wish people would respond to this. Why did someone downvote me?
The article doesn't suggest only using 48kHz for recording and mixing. I don't think the author would disagree that recording triangles is difficult. He would argue that once you've decided what final audible frequencies you want to present to the listener, the best way to distribute them is at 16-bit 44.1/48kHz. It's a compelling case.
The "next" links from http://www.guidetoyc.com/the-guide/5-idea/ points to http://www.guidetoyc.com/the-guide/6-customersdistribution/, which doesn't exist. It should be http://www.guidetoyc.com/the-guide/6-users-distribution/

The key to reproducing the original signal from the digital signal is a low-pass filter that rejects everything above the sampling rate, correct?

That is to say, what I am getting at is while the original signal can be reproduced, it requires properly tuned, and probably reasonably high performance, hardware to remove the higher frequency components of that square wave. Can you count on consumer grade hardware to do this well?
> Digitally recording a triangle is the best example of why 48kHz is very limiting

The article's about distribution, not recording. I don't think anybody disputes the usefulness of higher sampling rates when recording.

> In theory, it's true that the human hear can't hear above ~18kHz, but it can hear the influence of the very high pitch harmonics on a lower frequency.

...and 48kHz audio contains those lower frequencies.
