Edit: I'm here from the main page as well. Googling around I found this book "The Hobbyist's Guide to the RTL-SDR: Really Cheap Software Defined Radio" on Amazon:
https://www.amazon.com/gp/product/B00KCDF1QI/

You can read it for free with a 30-day free trial of Amazon books.

It goes through everything from setup to advanced usage so I'm gonna give it a shot. Hopes it helps other people get started!

u/Beagles_are_da_best · 30 pointsr/AskElectronics

Hey there, I happen to design electronics for construction and ag equipment. Construction and ag companies generally like to use the automotive EMC standards as a baseline so I am familiar with those standards and designing for them (ISO 11452 for radiated/conducted immunity, ISO 10605 for ESD, CISPR 25 for radiated/conducted emissions, ISO 16750 vehicle battery transients, ISO 7637 vehicle transients). I think it's helpful to walk through the required tests and determine what protection you need for each.

For the purposes of this post, I will assume that your "RTD signal conditioning" block consists of some sort of op amp circuitry or similar.

ESD


A suitably sized TVS diode is my go to. I usually choose it based on the data sheet calling out that it meets a particular ESD standard that is comparable to the one I am using. However, for analog lines you need to be careful about leakage current from the TVS diodes causing error in your analog reading. Maybe that's why you have the resistors in series? I haven't seen that before. Overall, set the clamping voltage of the TVS to something higher than your analog signal voltage so that you are guaranteeing an acceptable amount of leakage current from the TVS diodes for your application.

When you lay out your board, you need to put the TVS diodes as close as possible to the connector pins. make connections between the connector pins and the TVS diode pads as wide as possible, up to the width of the pads of the smallest component pad. Do not have any traces routed to your connector pins in between the connector and the TVS diode. You want the easiest path for ESD to go is directly to the TVS and shunted back out onto the cable connection. Any traces that need to be connected to the connector pins should be routed to the TVS pads. This is absolutely critical for passing the packaging and handling ESD test where the unit is unpowered and they hit the connector pins directly with +/-8kV.

Now, one more thing about ESD. You will likely have to pass a test where the unit is powered and ESD (+/-8kV direct, +/-15kV air typically) is applied to your device. Zaps are applied to locations that could touched when the unit is plugged in and powered. So, no TVS is really going to help you here because your connector pins are likely not exposed (since the connector is plugged into something else). The path for ESD to your board is not through the connector and thus you need to protect the board in other ways. This is where you need to either (a) ensure that any zaps applied to your electronics go around them and straight to ground (e.g. a grounded, metal housing) or (b) ensure that you have no exposed metal subject to the ESD test that is within 15-20mm of your electronics (use mechanical design to ensure nothing an be zapped that will be able to jump to your board). Why 15-20mm? Well, the dielectric strength of air is about 1kV/mm. With 15-20mm, you are ensuring that you have at least 15-20kV of isolation between the ESD gun and your board. Consequently, there is no path for ESD in that case. If you can't do that, then you are down to changing materials, adding shields, using "tortured path" mechanical design, or just simply having to deal with ESD on your board and the effects of that (bad!).

Immunity (i.e. protecting against injected noise)


Here you're likely looking protecting against noise at frequency ranges in the 1MHz to possibly 3GHz range. It depends on the company you are designing for usually. However, this is where you usually want to start off with a pi filter (cap - ferrite - cap) right after your TVS diode. A good bet is something like a 0.1uF cap - ferrite - 0.1uF cap. Whatever you do, you want to try and filter in the frequency range where the test will be done. One caveat here is that there are some standards (ISO 11452-4) where there is a bulk current injection test. It's a lot to get into, but generally you need to take special care in passing a BCI test if it is required.

Emissions


You have two circuit defenses against emissions. The first and best is to have ample decoupling and bulk capacitance on your board. Conduction emissions is a result of your board not having enough local charge storage and thus pulling high frequency currents across your power cables. This can also lead to radiated emissions. Two things are critical in providing this local storage. (a) You can't have too many bulk caps. Use many and ensure they are sprinkled about your board so that no IC is more than say 1-5mm away from bulk capacitance. (b) Decoupling caps need to be placed as close as possible to the VCC pins of each IC. 0.1uF is a good starting point. Keep traces very very short. Keep vias to ground and power planes directly off of the side of the cap, as close as possible to each other to keep the loop areas small. The more you do this, the more effective they will be. Multiple vias for each connection to the power and ground planes can be used to increase performance too.

The second circuit defense for emissions is the pi filter from the Immunity section above. That will help filter remaining emissions before it reaches the cables and outside world where emissions are measured. Conducted emissions is typically around 150kHz to 100MHz. Radiated emissions is typically higher, about 200MHz to 3GHz.

Board Layout


This is where EMC performance is made or lost. You need to be a complete stickler about your board layouts. Don't settle for bad practices in layout because they will be the thing that kills your EMC performance. I've mentioned a few layout related things already, but here's a couple more.

  • Board stackup - I won't go into too much detail, but more layers = better performance. A 2 layer board is almost guaranteed to fail emissions testing. 4 Layer is a minimum. At my job, we use 6 layers as our standard. Your goal here is to tightly couple the signals to the planes by having small dielectric heights and the proper layer order.
  • Component placement - Always filter at the periphery of the board. Keep all other components away from the connections to the board (13mm is a good rule of thumb here). Keep components at least 2mm away from the edge of the board. Keep sensitive analog circuits away from digital circuits (note that a digital trace can have return currents up to 50x the dielectric height away from the digital trace. A digital trace routed on an internal layer will reduce this to 3x. You want to ensure those high frequency return currents are not interfering with your analog circuits. Keep separation there but do not break up the ground planes. Thou shalt have one ground plane!
  • Critical trace routing - Mentioned this above but route fast traces first and keep them away from the analogs. Use internal layers if you can. Never route a trace over a gap in the ground/power plane. Never route a trace over an area without ground/power (i.e. at the edge)
  • Ground/Power Planes - Pull ground plane back at least 0.5mm from the edge of the board for avoiding manufacturability issues. Now, pull the power plane back another 0.5 to 2mm back from the edge of the ground plane to ensure that stray fields are contained on the board.
  • Routing with layer transitions - Any time you switch layers and the trace now has a new reference plane, you need to provide a stitching cap or via to allow the return currents to make it to the new reference plane within, say, 1mm of the layer transition. An example of this would be a 4 layer board where a top layer trace goes through a via to the bottom layer. Where that happens, you want to add a decoupling cap (0.1uF) right there between the power and ground planes.

    These are the types of things you really want to take care about if you are serious about designing high quality boards for automotive. Henry Ott's book is a great resource that I feel can greatly help explain the above comments in much better detail than I can here.

u/RabidCoyote · 24 pointsr/SEO

As someone else said - don't spend $900 on this. There's nothing you can't learn through the internet.

I started with the SEOMoz Beginner's Guide - it's lenghty, but free, and after reading it you should have a solid understanding of where to go through there.

I also own The Art of SEO which might be good if you want to get serious about it and have a reference on hand.

I read Search Engine Land daily and check the SEOMoz blog regularly. There are plenty of good news sources, which are important to keep up on as things change so quickly. Those are the two I read most often.

Knowing the basics of HTML, PHP, hosting and such will also help you in SEO; and there's CodeAcademy and Youtube for that. I'm assuming you are familiar with HTML but if you aren't it's easy to learn. PHP and SQL is good if you're looking to get more advanced but you can do without.

If you want to send me the link to the website I can make some broad recommendations. Most importantly, have a goal. Is it e-commerce - you want someone to buy something - or articles that you're generating ad traffic on? SEO is marketing, so understand what you're selling and who you're selling to.

Best of luck - I got into this about 2 years ago; I'm a marketer and SEO is there; but I'm hoping to use it to eventually reach a management/director position down the line.

I followed the rabbit-hole a bit, and landed at this book: https://www.amazon.com/Practical-Cryptography-Niels-Ferguson/dp/0471223573/

In which "double SHA-256" is discussed as a way to prevent attacks on SHA-256 from affecting your hashing algorithm. There's a known advantage to running multiple rounds of a hashing or encrypting algorithm (see bcrypt which is recommended for multi-round hashing of passwords for storage in a database).

There are also semaphores which are the beginnings of telegraphy that eventually evolved into the internet. Here’s a book about our first telegram president, who was much better than our Twitter president. And here’s a book with the history of telegraphy comparing it to the modern internet. But it all started with flags as letters. Fun fact, semaphores are also a thing in programming. It’s flags all the way down.

u/surrakdragonclaw · 19 pointsr/vermont

>Just give it a read and let me know what you think. Thanks

sure, have an upvote and a real reply: I think the Forbes article makes a bunch of big, ideological claims that I simply don't agree with, such as

> The U.S. government has shown time after time that it is ineffective at managing much of anything.

I don't want to get into a big debate overall about liberalism versus libertarianism, so I'll just say that a comment like this is flamebait which is going to rile up people who disagree, and get those who agree nodding their heads. So, we should should instead try to focus on very specific things. I think this article does a very bad job of that, to me it reads basically "private industry good [citations needed], government bad [citations needed]." If we look at what we have in other utility industries (I work in Power) -- power is mostly a confederation of regional monopolies which have been very tightly regulated. I think in 2018 internet access is more like a utility than it is like television, and I think that model might work to some extent. Now we're in an era of that regulatory grip loosening in the power sector, and there is certainly interesting innovation happening as a result, but, two key thoughts there:

  • The starting point for deregulation was already being in a situation where every household in the US could get electricity. We're nowhere near that with broadband.

  • The kind of deregulation happening is far short of the complete land-grab "let the telecomms do whatever they want" that Ajit Pai is suggesting.

    > If the telecoms are forced to compete in a truly free market, Comcast and Time Warner won’t exist 10 years from now. They’ll be replaced by options that give us better service at a lower price.

    Again, huge red flag and citations needed from where I sit; the existing entrenched telecomms in many cases own the lines and the copper right down to the last mile. Disrupting that is not going to be as "easy" as disrupting the cab industry or something.

    I am equally dismissive of the second article because the author very clearly states that they're not a subject matter expert and then makes a bunch of dubious claims. Comparisons to the early days of the internet do not hold water for me; I was online through a VAX server in 1991, it was a completely different landscape, it was mostly limited to military and academic use and had almost no utility to the average person. Also, the internet was (and still is) a government weapons project. That's tangential, but this book is pretty good because it paints the whole mythology of the internet in a very different light and makes a strong case that at its core it's a surveillance system for government and corporate interests: https://www.amazon.com/Surveillance-Valley-Military-History-Internet/dp/1610398025

    The article suggests that there is zero middle ground by which we could have basic neutrality ensured and also allow, for instance, T-Mobile's Binge On to be legal. That's much too black and white, so it strikes me as either naive or willfully obtuse.

    Okay, I read your articles end to end, here are a couple I would offer:

First of all, for any software development questions you may have, I suggest you post your questions on Stackoverflow because the people there will surely provide you with answers.

Now, for a list of books I recommend:

JavaScript

JavaScript: The Definitive Guide; if you're new to JS, start with this one.

JavaScript: The Good Parts; not a beginner's book, but a must-read if you are going to use JS

If you are going to be using JS, you will most probably be developing using a framework, and for that I seriously recommend mastering jQuery because as they say, you will write less and do more!

CSS

CSS Mastery: Advanced Web Standards Solutions

Web Usability

Don't Make Me Think: A Common Sense Approach to Web Usability; the book that shows the users' perspective when viewing a website

Performance

High Performance Web Sites: Essential Knowledge for Front-End Engineers and Even Faster Web Sites: Performance Best Practices for Web Developers;if you want to get serious about performance for your websites

Aside from the books others mentioned, I wanted to also suggest one that recently came out: "Serious Cryptography" by Jean-Philippe Aumasson. What I like about this book is that it focuses on teaching crypto via programming practical implementations. So if you like coding and learning by example I highly recommend it.

This isn't new. I witness the same behavior on newsgroups before the Web even existed (well, it existed, but its whole contents could be listed in a book). It is partly the anonimity, but mostly the fact that there are additional "filters" to the conversation. This also happens with phone conversations, or by writing letters: people could say things using these they would not in a face-to-face conversation. The distance created by the media lowers inhibitions.

He has been a fraud since day one.


  1. His twitter mentions that he is a "Best-Selling Author of Decentralized Apps". Which might be referring to his book released way back in 2016, with 17 reviews, a 3.0 overall rating and multiple fake 5 star reviews.
  2. He doesn't list any of his work with Udacity on his LinkedIn profile or his website. This was way before the scandal unfolded this month.
    This is really surprising because he has been a part of at-least 2 nanodegree programs with Udacity for around 3 years.

I think the guaranteed admission to the other programs is the real seller here, not the content. And they know it.

I also found the guy obnoxious and his tendency to call himself a "YouTube star" is a red flag to me. He gives me the impression of tending towards fluff. Reviews of his book:

Despite all that, I am still considering enrolling because of the guaranteed admission to the other programs. Now whether those other programs are any good, I don't know.

A part of me is really skeptical that they can produce a job-worth autonomous vehicles engineer in a year. Perhaps a sort of technician maybe at best.

u/hoytech · 6 pointsr/programming

Good question. Iterative hashing in the hope of finding a short cycle actually has a name: the "rho method". It's called this because the lowercase greek letter rho (ρ) has the shape of a detected cycle. The idea is that if you find such a cycle, it means you have found a collision in the hash function (the value before you entered the cycle and the last value in the cycle both hash to the first value in the cycle).

A memory-efficient algorithm to search for these cycles is the "tortoise and the hare" algorithm:
https://en.wikipedia.org/wiki/Cycle_detection#Floyd.27s_Tortoise_and_Hare

The algorithm involves keeping two values and double-hashing one (the hare) and single-hashing the other (the tortoise). If the tortoise is ever the same as the hare then you've found a cycle.

The rho method has several applications, but in the context of cryptography there is a very accessible description in this recently published book: https://www.amazon.com/Serious-Cryptography-Practical-Introduction-Encryption/dp/1593278268/

u/TheSuperficial · 6 pointsr/programming

No question, W. Richard Stevens' books on the protocols and the implementation were the definitive works.

I haven't gone back to them recently to see how they've aged, but much of what I know about TCP/IP, I learned from those books. (I was tasked with switching over the internal communications on a large telecom system from a proprietary protocol to TCP/IP - again, I'm talking about the communications between boards in the system, not outside to switching centers and COs.)

Unfortunately, Vol. 3 pre-dated HTTPS (and SSL in general), too bad, I'm sure if he were still alive, Stevens would have done that topic justice.

This gives you a great foundation, it's extremely well written and a nice reference to go back to.

I also recommend Practical Object Oriented Design in Ruby

This book is just amazing. If you're new to object oriented programming, and even if you have a bit of experience, this is going to improve your skills dramatically.

Good luck!

In addition to that, these resources might also be of interest to you:

They also have a book that will cover much of the basics from the different radio's you can get, antennas, filters and a walk through of large amount of projects. If you want to go a bit deeper you should check out the book Field Expedient SDR: Introduction to Software Defined Radio. There are three books to that series.

As for your first SDR Nooelec NESDR Smartee bundle is a great start. Once you have an idea of what other projects you want to work on you can upgrade to something like LimeSDR (or mini) or a hackrf. I would recommend the LimeSDR Mini.

u/bobishardcore · 5 pointsr/learnjavascript

JS is hard, especially for people new to programming. Basically, JS as we know it today is an evolution of a browser hack that only recently became a seriously useful language. The syntax is terrible, math and numbers don't make any sense, the regex system isn't super robust, oh and it's not really an OOP language. Technically, it is multi-paradigm and includes some oop-like things and classes are on the way to browsers, but it's for naught anyway, because you don't need classes in JS - It's a prototypical inheritance based language.

If you're new to programming in general, I'd say you should start with a more sane environment, like Python. It will teach you programming concepts while railroading you into making good coding decisions. It's really common for people to start with Learn Python the Hard Way - don't. Go to /r/learnpython and search "LPTHW 31" and just count up the people struggling with it. Zed Shaw is an idiot, there are better things to read, I'd recommend watching the google IO talks, get a buddy to learn with. Honestly, I've never read a python book cover to cover, but I feel pretty comfortable with the language from just googling "How do I do X in Python" millions of times, usually if a link comes back to docs.python.org, I click that one first. The docs are wonderful, you don't need a book.

But, since JS is one of the most important languages due to it's integration with the most common form of media distribution in our time, I'd recommend reading / watching talks by Douglas Crockford. Check out Javascript: The Definitive Guide and Javascript: The Good Parts. The second one is a little easier to digest, while the first is really the definitive guide.

In both cases, I'd recommend doing the challenges on hackerrank.com.

u/Johnny_Walker_Red · 5 pointsr/rubyonrails

The Rails 4 Way is excellent. It really covers everything, filling in gaps that you may have in your knowledge.


I would suggest reading this once you have a bit of rails knowledge. I've read the book over twice, and it was responsible for a surge in my rails knowledge/abilities.


I would actually suggest you make sure your understanding of Ruby is absolutely solid before you read the Rails 4 Way. It's not necessary, but I think the best way to learn Rails is to first have a full understanding of Ruby. That way, you truly understand what's going on under the hood when you're learning about various Rails features.


For Ruby, I recommend The Well-Grounded Rubyist. This is a great book, and it doesn't require you to code along with it (thought it does allow you to if you want, and it comes with sample code you can download).

Hi, I'm also an online business owner that wished to remain anonymous when I started about ten years ago. Throwaway account for hopefully obvious reasons. Like you, it's not nefarious. We sell a normal, high quality product... I just value personal privacy. A couple things have worked for me.

Method 1 was using a "Doing Business As", or DBA for short. This one's easy. Usually when you get a business license, you will have the opportunity to register any DBAs. This is usually used if your business name is, for example, Widget Holdings, LLC, but your store is called "Widgets R Us".

But you can also add whatever you want as a DBA. So you can add a personal name. This legally let me still use an assumed name while doing my business, sign contracts, add the name to a business bank account so checks to this name can be cashed, etc. without using or revealing your own name.

Method 2 is if you want a little more in-depth privacy. You can create a Limited Liability Company, or LLC, for a similar purpose. For example, you would register Sally Draper LLC in a state with lax information requirements like Wyoming, Nevada, Delaware etc. Since LLCs are often legally treated as a person, you may now use Sally Draper when opening bank accounts, owning or registering property, even signing a lease, etc. without ever revealing your name.

If you want to do this with nearly complete anonymity, you can find people in these states who will perform a unique service for you: You register the LLC, and are only required to list an agent and in-state address, which this person provides. Any official LLC mail will be directed to their address and forwarded to you, and these people will not reveal the name or information of the owner/principal(s) of these companies unless compelled by a search warrant. So if you aren't concerned about the law, this is golden. Usually costs a couple-to-a-few hundred a year. If you want more guidance, How To Be Invisible is an excellent resource for this and a great many more aspects of remaining private in situations like yours.


Just one word of caution from my own experience using an assumed name: First, my thing really took off and despite my caution, locals eventually found out about my business, including people who knew my real name. Out of the blue, a well-known local magazine reached out to do a write-up. Now, do I use my business name and confuse people who know me? Or use my real name and compromise my setup? I chose to stick with my DBA since it was professional, but either path leads to some confusion.

Also don't let customers do local pickups! Drop off or make 'em pay shipping. Locally, it's not that expensive.

  2. Build your own acoustic panels using a wool or recycled denim based insulation. The deeper the better.
  3. Install those panels at your early reflection points on your walls and ceiling...and behind your speakers.
  4. Get one subwoofer, preferably two.
  5. Put isolation under your speakers.
  6. Get some monitors that don’t suck.
  7. Use an RTA with a transfer function to identify problem frequencies and locations.
  8. Build your own helmholtz resonators to address low frequency problems.
  9. Use more acoustic panels to address any high end frequency problems.
  10. Diffusion on your back wall can make your room sound a lot bigger.

    Read a book. There are many, but Sound Reproduction by Floyd E. Toole is a must read for every audio “Engineer”.

It doesn't get into the algorithms but instead the different types and modes of encryption, when you would want to use them, and why. That can serve as a nice jumping off point to more detailed research.

I got the airplane tracking thing going and also read my power meter broadcasts (and my neighbors). Found a bunch of medical pagers and police/EMS freqs. Also a bunch of weird things, including a neighbor who apparently watches TV while wearing RF wireless headphones.

I had a very difficult time capturing any frequencies I found listed online. In particular, I didn't find even one Ham thing of any kind. I know the HF freqs are out of reach, but the repeaters etc should be there. Radio silence.

>>> Would you say that the majority of linux administrator jobs out there are partly plain help desk support?

No, not the majority. Help desk type support is in the "IT" or "Office sysadmin" category. You can avoid those kinds of jobs especially since they usually require windows administration skills/knowledge.

>>> Or is there something else, something more advanced where you wouldn't have to deal with ignorant users, fixing the same issues over and over again?

Most internet type companies with funding and a practical business model will have "IT sysadmins" who support office/user systems and another group (something like "operations") that handles design, infrastructure, and maintenance of backend multi-stage environments. It seems like the latter is what you're interested in.

>>> Are there any particular technical skills (related to linux) that I should focus on to make myself more appealing to the employer?

  1. Be, or appear to be, eager to learn anything and everything.
  2. Read this book: http://www.amazon.com/TCP-IP-Illustrated-Vol-Implementation/dp/020163354X
  3. Build a linux server. Build several linux servers of different flavors. Build BSD and solaris servers. Build and try out any OS you can get your hands on. Check out firsthand what's awesome and what sucks about each.
  4. Learn a scripting language. Bash/shell is the most universal, but people have their preferences. I think python and ruby are what's in demand these days.
  5. Learn how to use the vi editor, even if it's at a very basic level.
  6. Break shit and figure out how to get it working. Fixing things that you didn't break is the most impressive thing you can do at a job. And the faster you fix things, the more impressive it is.
  7. If a potential employer asks you what you did during that year long gap in your resume don't say, "Not much. Well… I drank a lot."

    The most successful unix sysadmins I know are always learning new things. Most of them would also be classified as alcoholics, but that's a different question for later on in your career.

The Victorian Internet (user review excerpt):

> The parallels between the Victorian Internet and the present computerised internet are remarkable. Information about current events became relatively instantaneous (relative, that is, to the usual weeks or months that it once took to receive such information). There were skeptics who were convinced that this new mode of communication was a passing phase that would never take on (and, in a strict sense, they were right, not of course realising that the demise of the telegraph system was not due to the reinvigoration of written correspondence but due to that new invention, the telephone). There were hackers, people who tried to disrupt communications, those who tried to get on-line free illegally, and, near the end of the high age of telegraphing, a noticeable slow-down in information due to information overload (how long is this page going to take to download?? isn't such a new feeling after all).

u/Mr-Mud · 2 pointsr/audioengineering

You have justified your logic, but, with all due respect, it is flawed. It reminds me of a joke about a scientist that taught a fly to fly on demand, and observed that when he removed it's wings, it went deaf, because it didn't fly on demand anymore!

The human brain is tricked very, very easily. In 1910, Muzak was invented: phycological based music systems! If you have any doubt on how easily the brain can be tricked, PLEASE search for audio myths on reddit and watch and listen to the videos. It will blow your mind, if you believe what you wrote. They demonstrate just how easily the brain is tricked. In fact, you can be talked into hearing things! Fact. The softwares we are speaking of, such as Sonnarworks, measures reflections on a spectral analytic basis, as well as time differences, as well as phase and inversions, natural comb filtering and much, much, much more.

It does, indeed negate the effects of the room, actually better than room treatment, in most cases, so your speakers are indeed sounding as if they are in an anechoic chamber.

>On top of that there is a frequency curve and we perceive different frequencies at different volumes.

It does take into effect the fact that human ears are most sensitive at 1000 hz and the rollouts of the human ear. For headphones, they go as far asking for you to send in your cans, as they measuring each side of YOUR headphones, for they differ, it is that accurate. Andrew Shepps ( if you into audio engineering, you know his pedigree - If you don't, you should) swears by it, as more and more engineers are, and they are in fact using it to mix now - grammy winning mixers using it and swearing by it - I'm not second guessing Schepps and his golden ears. I'm not going to challenge the incredible work Sonnarworks engineers either.

>Throw a digital room correction into the mix and you are now lying to your brain and it can no longer tell fact from fiction.

This is baseless, my friend. High end home theater has been doing this for well over decades with wondrous results, in high end home theater, I'm talking the custom stuff, a point source mic is put at every listening point in the room to correct the room. The before and after is stunning - jaw dropping. The consumer's brain doesn't 'fix it'. Even regular consumer home theater, best buy stuff, has Audyssey MultEQ XT32, LFC, Sub EQ HT, Dynamic Volume and Dynamic EQ. Sonnarworks has taken it to pro level.

>our brain can perceive this room correction and correct for it in the mixing process, because at least your brain is hearing the truth

Our brains lie to us, our brains lie to us every day, for it tries to quickly piece together bits of sounds, and sights, for that matter, and quickly try to come up with something that makes sense. i.e. the man on the moon syndrome: our brains try to do it's best to create a whole picture out of pieces. It does the same to audio. I'm sure you've seen optical illusions. They work extraordinarily well! Sonic illusions do too!

>Your brain can perceive this room correction and correct for it in the mixing process, because at least your brain is hearing the truth.

Now we're getting ridiculous. If this were true, than why do all, as in every one, without exception, of the best mixing and mastering engineers treat their rooms? Because their brains cannot decode the complex array of waves bouncing all over a room.

>Throw a digital room correction into the mix and you are now lying to your brain and it can no longer tell fact from fiction.

Where are you getting this from? You just pulled the wings off the fly! I'm not sure if you can tell fact from fiction, as you are writing baseless fiction, posting it as fact. Are you Trump???

>Digitally correcting a room is imperfect and leads to worse results than the original uncorrected signal.

This is America, you are certainly entitled to your own opinions, but nobody is entitled to their own facts.

I mean no disrespect, but you are misguiding the OP with baseless nonsense. If I understand you right, your point is, the more you do to correct for ones room's imperfections, the worse sound you are going to get. by extension of that theorem, no room should be treated in any way, physically or electronically.

Look, I'm usually a really nice, helpful guy on Reddit. I rarely will call someone out. But your uneducated statements are wrong, on many levels. They are baseless, incorrect, misguiding and it's not a very nice thing to do to the OP and others who might think what you are posting is fact. At least the first poster started his post with, "this is simply my observation.....".

Now I'll give you that the brain can 'learn' headphones or speakers, and even a room, (to a very small degree if at all). You can only to an extent on, all of them. The issue is, we are never finished learning them....ever. That's why we listen to our mixes on different transducers in the studio, headphones, the car, and as many different places, because we are never sure! We never ever fully learned a pair of speakers or even a room with room treatment!

Also, one thing I have prepped on is bringing back cellular service. If you have an OpenBTS tranciever station backed to a working PBX, you can restore cell service for a small area (1/4 mile) using minimal equipment.

Cell towers won't last beyond 2-3 hours without power. I know from experience: I was in the 2011 Southwest Blackout. The backup power failed on most of the towers within 3 hours. It was a complete grid-down situation for 13 hours for my area. Nothing worked (not even the water or gas)... except my old dial up modem which had backup power ;). My local grocery store got fully cleaned and looted within the first 4 hours. Traffic completely ground to a halt. I mean a complete halt. We didn't move even 2 ft for an hour, and we chose to abandon our car like everyone else and walk a couple miles back to my house (which we just left from). There were other problems too:

>The outage caused significant losses to restaurants and grocery stores, which were forced to discard quantities of spoiled food; perishable food losses at grocery stores, eating establishments and households were estimated at $12 million to $18 million.[14] The outage also caused some sewage pumping stations to fail, resulting in contaminated beaches and potentially unsafe water supplies in several areas.[15] As a precaution, in some neighborhoods, residents were told to boil their water or use bottled water for several days after the outage.[16] Due to the failure at the sewage pumping stations, diesel generators have been installed at five pumping stations.[17]

>The hardest hit region of the blackout, the San Diego-Tijuana metropolitan area, was essentially brought to a standstill. Surface streets became gridlocked due to the loss of traffic signals, and the San Diego skyline went dark. The San Diego Trolley system was shut down as there was no power to operate signal lights and related functions. Citizens in Tijuana and in inland areas like the Coachella Valley stayed outdoors late into the night to escape the heat.[6] Freeways in the Southern California megalopolis experienced extreme clogging, especially on the I-15 and I-5 corridors between southeastern Greater Los Angeles and the San Diego area's North County.[6]

I know a lot of people back east are like "meh, 13 hours, try 3 days." But it is completely different dealing with a blizzard where everyone is locked indoors, and a heat wave without power. Things fall apart a lot quickly when there is not extreme weather preventing people from going outside. It was like a lightswitch: Now there's infrastructure, now there isn't. I was in a blizzard about a decade ago in the PNW where the power went out for a couple days, and it was no big deal. I'd much rather be in that situation than deal with normal clear weather where the power grid, cell systems, water systems, gas systems and core networks just disappear from the map for a day. It gave a real clear view of what would happen if shit really hit the fan in a metro area. Pretty much all infrastructure will die off within a day or two, including water. Thankfully POTS is always really reliable in extended outages, and if you can find a working phone line anywhere you can jump back online and into an IRC channel or other low-bandwidth message system to get information flowing again. Land lines will usually last well over a week without power, they're usually the absolute last communication network to go down, they can be vital for getting information in and out of an area that's in crisis.

I was in your position, so I can tell you there's not a lot out there that walks a software person through radio and even less that walks a software person through ham radio. I'll share some key things that helped me:

  1. The RTL-SDR book is pretty good. They don't explain a lot, but the projects are OK and give you a direction to work in and show what's possible.

  2. You can get an amateur radio book, but be prepared to have to make some connections yourself. Like, they talk a lot about modes. Amateur radio "modes" are basically what you and I would call protocols: An agreement to transmit and receive using certain conventions. The ham radio sources are almost 100% directed at explaining new ham things to people who are already in the hobby, not explaining things to outsiders--it's really frustrating.

  3. You can understand a lot with some pretty simple mental models. Radio stations (large and small), sometimes they transmit analog sometimes digital, etc. However, if you want to understand settings like "FFT size" or "LNA" and why you can only see a certain amount of bandwidth or if you want to build your own application from scratch, you need to dig into the mathematics of digital signal processing (DSP). My favorite free resources for that are:

    a. GreatScottGadgets shortish overview of some basic concepts from an SDR perspective

    b. A really neat website that introduces many fundamental DSP concepts

    c. A free book that explains DSP in detail step by step

I thought about the writing extensions part myself, but i think it is too much stuff to cover.

I'll probably put some reference (there is only one -decent- book anyway on the subject : Extending and Embedding PHP ), there is a couple articles on Zend.com that do a nice job on this specific subject.

There's a great little book that talks about this, called The Victorian Internet. It's a history of communication, and shows a lot of parallels between the advent of the phone to today's internet (and how people were afraid the phone would be the downfall of society). But it's full of interesting stories like this.

Okay, so I know it's been over three weeks since you asked, but I'm going to go ahead and answer, anyway.

I graduated with a BA in Professional and Technical Writing in May 2010. I didn't get my first job until January of this year and that required me to move across the country. There are a lot more technical writing jobs in metropolitan areas.

I don't know if you've got another career and are looking to try something different, or if you're trying to decide what to do after college. Either way, employers want experience. I was actually really lucky to get my job with no experience. They tried two other people who didn't work out so they gave me a call.

Overall, I love my job. I learn something new every day. I'm working for a software development company and I knew nothing about software development before I started here.

The work can get a little tedious at times. Also, this definitely isn't creative writing. I work on a lot of proposals for government contracts and 90% of the content is copied and pasted from previous proposals, then tweaked to meet the requirements of the new proposal.

All of WitchDr's advice is good. I'd also recommend working on your portfolio. Create a website. Write a manual for software or a product that you use.

I also think you should learn HTML. This book is awesome.

My understanding is that placing the caps on the other side of the board isn't optimal, but will work, so long as you remember to keep the connections low inductance.

As for the value, it's partly determined by the frequencies you'll see in the circuit.

When considering the frequencies of the board it's best to look at periodic high frequencies, like clocks. But remember, because the clocks are "square waves" not sine waves there are a lot of higher order frequencies contained in them. Take the Fourier transform of a trapezoidal wave to see what I mean. These higher order frequencies are the ones you need to worry about.

0.1uF is good for circuits that are lower frequency, above 100MHz or so a lot of engineers will use 10nF or smaller caps for decoupling.

Check out a book on EMC for more information. [This] (http://www.amazon.com/Electromagnetic-Compatibility-Engineering-Henry-Ott/dp/0470189304/ref=sr_1_1?ie=UTF8&qid=1333128646&sr=8-1) one contains a lot of good information of board design.

Edit: One thing I think forgot to mention is that you should generally route power and ground first. If you're using planes on inner layers this is really easy, if not try to make a grid of power traces on one side and ground on the other. This is because each parallel connection you have that is far enough apart to minimize the mutual inductance will reduce the overall inductance. At it's limit this becomes a plane.

Once you have your power and ground routed then do the clocks, then the digital signals.

This does not address the issues with analog signals on the board, as they should be segregated from all digital circuitry and power supplies.

I think you just don't understand the logic behind javascript. Maybe the auto-insert semicolon thing is annoying, but if you want to seriously use any language at the expert level you really should read a book about it. I recommend The Definitive Guide if you actually want to improve your skills. Javascript is more complicated than it seems at first. jQuery greatly helps manipulating the DOM if you are sick of browser compatibility issues.

Yes and no. Its better in some ways in terms of security or privacy in terms of the sensible defaults you get, but its ultimately up to you to keep things secure and private. There are no magic bullet solutions, and you should be careful to avoid the cargo cult mentality.

If you want to take your privacy seriously, I would highly recommend that in addition to starting your Linux journey, please pick up a book titled The Art of Invisibility by Kevin Mitnick. He is a legendary hacker, but wrote this book for a wide audience. It does a great job of covering the most important issues, while remaining easy to understand. I also recommend his other books that tell stories about hacking and social engineering.

The US Navy developed TOR and spun it off into the private sector, and ever since then the US government has been giving TOR something on the scale of 70-80% of it's income. Read this book. The government needed other people to use TOR. It doesn't matter if the people and destinations can't be matched exactly if the only people using it are the government, every person and destination is still relevant. Hence, spinning it into the private sector to gain users to cover the secret shit.

The government likes TOR, having developed it and funded it. It's anti-government stance is mostly BS, like most tech companies.

Which really does make you wonder why the fuck the CIA didn't have its sources using TOR. After the Iranians found their sites, they just tracked people who went to it and where they accessed the sites from to find them. Easily could have saved their lives to use TOR and/or a VPN

Siraj wrote a book that can be considered a prelude to much of this. The difference is that the book was read, and heavily ripped apart, by people who actually know what they are talking about; and by people who can objectively criticize his work.

It makes sense that Siraj drifted into the YouTube space. Want to learn a programming language? Real engineers don't watch YouTube tutorials. Want to learn Machine Learning concepts? Real engineers don't seek out a collection of buzzwords.

This industry requires work. Siraj is a marketer.

> After much contemplation, wonder and imbibing of beverages, I return to thank you.

You should save the contemplation and beverages for when you get the eargear - it's a common witticism among audiophiles that the best upgrade to your system is a higher BAC :P

>On the contrary, this is fascinating! I'm in science writing (nonfiction and fiction), so I get to appreciate this kind of nerdery. It kind of answers this hazy question I have about why does good audio equipment cost so much. We're still sciencing it out, which is cool. I mean, that goes for most technology, so it's not unique, but for me, it's a whole new world.

If you like that, Sean Olive, a fairly major person in most of the above links, [has an infrequently-updated but occasionally pretty neat blog] (http://seanolive.blogspot.com/), and on the heavier end of things his mentor Floyd Toole has a [wonderfully detailed and IMO shockingly readable text on sound from a music/listening standpoint] (https://www.amazon.com/Sound-Reproduction-Psychoacoustics-Loudspeakers-Engineering/dp/113892136X/).

I will say, while there's definitely a component of development/progress being funded here - particularly in headphones, an area which has been seeing both a vast increase in prices and a substantial rise in quality over the past decade or so - I'd also point to two other factors driving high audio equipment prices:

The first is that, in many respects, audio tech develops exceptionally slowly - there were condenser microphones and electrostatic headphones made in the 1960s and 70s that are in many respects comparable to modern high-end equipment, and we haven't got that much more efficient at making them either. Unlike, say, integrated circuits, the core mechanisms of electroacoustic transducers haven't really become smaller, more efficient to make, or higher performance, at least to nearly the same extent, nor have we developed many alternative methodologies - we have better diaphragm materials, stronger magnets, and better assembly processes than in 1920 or 1970, but not to nearly the extent of, say, transistor or capacitor manufacturing, and almost all headphones, speakers, and prior to the smartphone revolution microphones are still the same style of moving coil design that existed at the start of WWI.

This, to some degree, keeps our buying power a bit low compared to what we're used to - I can get a 1980s supercomputer in my pocket for $100, but it's not that much cheaper to make a high-quality headphone now than it was then (and, indeed, some high-end headphones from that era that have persisted since then - Stax's Lambda series, for example, and Beyerdynamic's DT880 - have seen their prices track with inflation for the most part, or in some cases rise).

Of course, I'm neglecting the increasing use of modern technology in some bits of audio tech - digital signal processing, in particular, has immense potential, and has yielded exceptional results in many cases - but that's partially because the field of high-fidelity audio has been comparatively slow to adopt things like digitally controlled speakers and headphones, and where they do exist they tend to in fact be closer to the commodity end of the price range than the high end (and, sadly, they often underperform their potential as a result of this lack of attention).

The second is that the higher end of audio equipment primarily consists of [Veblen goods] (https://en.wikipedia.org/wiki/Veblen_good) - while there are many fine speakers, headphones, amplifiers, and so on available at higher price tags, for decades the highest end of the hobby has been defined at least as much by luxury and status as by actual technical performance. This isn't really that pertinent in the price ranges that sane people talk about - a $100-400 headphone or speaker definitely has some status signalling component for its buyer, but it also just plain costs money to make these things, and often as you climb past the "sold in gas stations" price bracket you see massively diminishing sales volumes, with the attendant loss of economies of scale. That said, outside of "lifestyle/consumer" products, a lot of the field is driven by the eccentricities of the higher end, and when that segment isn't looking for cost reduction (or, in fact, may be looking for the opposite), it has some weird impacts on how resources are allocated and what sorts of products are developed, even outside of the realm of $10k/meter cabling and $200k per pair speakers.

Erm, sorry to ramble at you, but I'm really into this stuff, and sometimes I get carried away.

>Makes sense. Would my unrefined taste buds really appreciate a $1,000 bottle of wine over a $30 one? Probably not.

Oenophiles are a [common comparison point with high-end audio] (http://nwavguy.blogspot.com/2012/04/what-we-hear.html), as a matter of fact - although usually from the standpoint of "past a certain point, you aren't really getting more quality" rather than "your palate isn't refined enough" in my experience.

> I have no idea what this means but it got me searching how do brains process sound, good stuff.

It's a really fascinating topic, although I'm mostly hip to the parts that are pertinent to headphone design (my profession) more than the neurological (or physiological in general) side of things - in general, once you get to the eardrum, my job is pretty much done. A lot of weird stuff happens by that point, however - you can spend a fair while just getting your head around how the binaural hearing apparatus lets us locate sounds in three dimensions.

> I think I want a better sound experience, and it's worth it in my situation to invest better in both speakers and headphones. I've actually decided to downgrade to the 3700x build in order to grab better eargear.

I hope that it ends up being worth your while! I'll be interested to hear your thoughts on the gear, if you have any.

The journalist in that website made Freedom of Information Requests toward several government agencies that provide Tor with funding. Most of these requests were shot down for national security reasons, but one of the organizations wasn't covered under such an exemption and the government provided him with the data he asked for. He then published emails between Tor developers and that one particular government agency that showed how The Tor Project provided the agency with newly discovered bugs that security researchers brought to their attention.

Here's the book that the journalist eventually published:

> After all if javascript is a language like PHP and built into the web browser it should be exactly the same everywhere. Shouldn't it?

Python, IronPython, Jython and Stackless Python are all different implementations of the same "Python" language, yet they're all subtly different. g++ and Visual C++ are two different of the same "C++" language, and yet they're both subtly to completely different in the subsets of the language they're able to handle, and the way they implement it.

So no, there is no reason that it should "be exactly the same everywhere" because there is no single Javascript implementation for everyone to use. And yet it does manage to be mostly the same everywhere...

> Standards don't apply

They actually do, "Javascript" itself, as a standard, is mostly well implemented across browsers (the only quirk I could list being the whole Date.getYear fuckup). The area where various implementations start differing is the DOM, which is not Javascript-the-language but Client-side-javascript-platform.

> Mochakit

MochiKit, please.

And it's not really a framework, much more of a javascript library.

> Rest assured Mozilla will soon create its own framework or library and make things "better"

Why the hell would they do that when they can improve the language itself (as far as they're concerned)? See Javascript 1.6, Javascript 1.7, Javascript 2.0

> Hard to find good books and documentation

Only when you don't know where to look.

Beginner? HowToCreate's JS Tutorial (http://www.howtocreate.co.uk/tutorials/javascript/important) is one of the best resource to get up-to-speed with the basics

Beginner or designer? Go for Jeremy Keith's "DOM Scripting" (http://www.amazon.com/DOM-Scripting-Design-JavaScript-Document/dp/1590595335/ref=pd_bxgy_b_img_b/102-8282999-1322522?ie=UTF8), clear book, not too advanced or clean javascript but more than enough to get things done.

Want some more? PPK's "PPK on Javascript" (http://www.amazon.com/ppk-JavaScript-1-Peter-Paul-Koch/dp/0321423305/sr=8-1/qid=1161173272/ref=pd_bbs_sr_1/104-4964908-7079955?ie=UTF8) is reliable AND practical, plus PPK's WebSite, QuirksMode (http://www.quirksmode.org/) is one of the most practical "advanced javascript" resources one can find, especially on the DOM issues. Could've been more advanced, but PPK wanted it to be an intermediate-level book, not a guru-level one.

You want to know everything there is to know about JS, or are a language lawyer? Javascript: The Definitive Guide 5th Edition (http://www.amazon.com/gp/product/0596101996/ref=pd_cp_b_title/102-8282999-1322522?ie=UTF8) is the ultimate Javascript book & reference. Everything you may need from scoping rules to interfaces to SVG and E4X is in there.

> The community is your only hope

Only a subset of the community is really useful, and most of it already has blogs. Most of the community, on the other hand, is completely and utterly clueless.

Above all, what one must realize to work with javascript is that javascript is not a "sub-language", a "toy" or a "scripting language", it's a full-fledged, dynamically weakly typed programming language.

And it's not java.

Care to elaborate on what you mean by functional program framework?

Are you talking about doing functional programming in C? I think there is a book on that. I think it's this one: http://www.amazon.com/Functional-C-International-Computer-Science/dp/0201419505/ - I'm not so sure though.

Are you talking about building framework/programs that are functional (as in robust, secure, ...)? If that is the case, then there is an interesting book named "C Interfaces and Implementations" going through several kinds of modules you might want to implement in C, and going through how you'd elaborate an interface and an implementation for them => http://www.amazon.com/Interfaces-Implementations-Techniques-Creating-Reusable/dp/0201498413/. This book covers the sort of thing that I believe you should be studying after learning the overall language syntax and semantics, how to combine features of C to solve not so trivial algorithmic problems, and so forth. In summary, it talks about modules design (both interfaces and implementations) in C.

There are more books here, like those listed in here http://www.iso-9899.info/wiki/Books. You can also check some more learning resources here http://www.iso-9899.info/wiki/Usenet and here http://www.iso-9899.info/wiki/Web_resources.

Still on my second interpretation of your functional program framework (because idk much about the first one besides that book "Functional C"), there are tons of very complicated systems built in C, like operating systems, server software, and so forth. And for many of them, there were books written. Here are some software for which you can find books on their design and implementation:
