Are there any good references on advanced PCB design/layout/routing?  There seems to be a large wealth of circuit design books, books about RF PCB design, and books dealing with high-speed digital design. None of these books are what I'm talking about. The type of book I am looking for is along the lines of PCB best practices for general digital/low speed analog/power supply layout &amp; routing. What is the de-facto standard book they use in college classes for this topic (similar to the way that Oppenheim et. al.'s  is used in many DSP classes, or Sedra &amp; Smith's  is popular in many Circuit Design Classes)?  Can anyone recommend a good PCB design/layout/routing book for this type of design?  Would a high-speed design book be a sufficient in that it would be overly-strict based on lower speed designs?

I was very inspired by Michio Kaku's  on the possibilities of quantum computing and also listening to Talia Gershon's  on it.   As I come from a business &amp; analytics background, what materials can I begin exploring to prepare to learn more about the field of quantum computing? Eg. what would I need to study to understand Peter Shor's algorithm,  on physics, etc.

What is your recommendation for an in-depth introductory combinatoric book? A book that doesn't just tell you about the multiplication principle, but rather shows the whole logic behind the questions with full proofs. The book should be for a first-year-student in college. Do you know a good book on the subject?  Thanks.

seems like a really hot topic and I'd like to start reading about. I am looking for the best introduction at my level, i.e. I have a background in QFT, CFT and general relativity at the level of a master student in theoretical physics. What would you recommend me to start tackling the subject? I have been looking for resources and so far I have noticed:  -this synthetic introductory lectures by Horatiu Nastase:   -the videos of lectures done by P. Vieira at Perimeter for Perimeter Scholar International students:   -the subject starts entering the most recent textbooks on string theory. We have the Schwartz and Becker (  ) and also the Kiritsis (  )  I probably missed a lot of resources, as the literature on the subject is already quite huge. I would really appreciate some advice on that, as I already had the frustration of losing my time on not-so-good books when started to learn something new, so if I could (to the best) avoid that this time...

I'm curious why PCBs have one square pad in row for 0.1" headers. What is purpose of putting one square pad? What it indicates? Can you push more amps through square pad than round?

I was hoping you guys could recommend reading material on quantum information. I have a good background in quantum mechanics, including in foundational issues, as covered in Ballentine's Quantum Mechanics.  I am interested in the intersection of quantum information and quantum foundations, such as in the works of C. Fuchs and in the research of the Perimeter Institute. While I prefer a more rigorous text, I'm trying to be as open as possible and would enjoy any suggestions or recommended reads.  Currently, I am reading the book by Busch, Lahti and Grebowski, notes on ArXiv by Keyl and also the notes by Preskill.

This is about the seemingly controversial shield to ground connection. The system is basically a body-worn intel-based computer, powered by a battery. Two USB 3.0 (or 3.1 Gen1) cables come out to a PCB that contains two USB 3.0 hub chips (). Two external cameras plug in to this usb hub PCB (one camera for each hub). So the usb hub PCB has 4 usb connectors (2 upstream and 2 downstream).  The question is, what to do with each of the usb connector shields? The main directive is USB connection robustness.  I have seen many recommendations. For example:  Recommendation 1  TI's TUSB8020B hub reference design  ties all shells directly to ground.    Intel's  also recommends to tie to ground (although this was written for USB 2.0).    Recommendation 2  TI's TUSB8020B EVM (and datasheet) connect shields together, and to ground using RC filter:    Microchip's  also ties shields together and uses an RC filter, but a 3 orders of magnitude smaller R:    Recommendation 3  Cypess  ties each shield independently to ground using either LC or L filter (chokes really):    The cameras themselves (off the shelf) use Cypress recommendation (LC to ground). The embedded computer seems to tie to ground from visual inspection and checking continuity to ground, but I'm not 100% sure (schematics are not available).  Now we face the shield dilemma with the hub PCB (which by the way currently does not have a metallic enclosure, it is a 3d printed plastic enclosure).   What is your say?

Can you explain me why and where I should put AC-coupling capacitors (usually around 0.1uF) on high-speed (1...5 GHz) differential serial interfaces (like SerDes for Gigabit Ethernet SFP modules)?  From what I have read, the caps should be placed as close to receiver pins as possible. Any legit references are welcome.  [CHIP1 RX+]--||-------------[CHIP2 TX+] [CHIP1 RX-]--||-------------[CHIP2 TX-]             0.1uF   [CHIP1 TX+]-------------||--[CHIP2 RX+] [CHIP1 TX-]-------------||--[CHIP2 RX-]                        0.1uF   Thank you in advance  UPDATE:  Got a reply from the IC manufacturer and it advised me to put the caps closer to the transmitter. So it seems that the actual place depends on how the particular IC works. A while ago, there was a completely opposite advise from another manufacturer.

I was wondering what book(s) is/are available for learning ArcGIS Desktop functionality.  I would like to use one in conjunction with books on the theory of GIS since even though I can understand the concepts I still have trouble with how to use the more advanced ArcGIS Desktop features.   I understand there are quite a few online tutorials but I do my best learning if I have a book in front of me.

I'm looking for the Book that explains the essentials of user interface and user experience design.   I read  and  from O'Reilly. I think they are very good but, I'm still looking for the one.  Please provide your recommendation and why it stands as the essential reference.

I am designing a prototyping platform called . It is a learning cum prototyping platform for students and makers. Since many times we requires debugging of our circuits, so I thought to include some testing points in PCB. I came across this image: It is used in Dr.Duino (debugging shield). Can anybody explain what it is? Or any other idea about how to give test points in PCB for users, such that user can easily attach the alligator (crocodile) clips or Banana multimeter cable tips.

I am looking for books about the physics of DSLR, including modern photography optics and sensor electronics. If I already have some books on optics and electronics, I have found fairly hard to find good resource for these fields taking photography as a basis, with examples taken from photography and chapters dedicated to lenses optics for instance.  So far what I have found is either too generic, or, if dealing with photography, lacks the physical expertise I would like to get (I mean books with equations. Everybody loves them.)  Good books for physics of photography exist, but they are quite old, the last good I have found were written by Kingslake in the 70s and definitely miss the non-optical part, and the optical stuff is a bit old-fashioned now (but very nice books BTW).  To sum up, I would like:   Very technical references Dealing with physical issues specific to DSLRs and modern photography, such as diffraction limits, image stabilization, properties of coatings, noise correction - whatever you can think of actually...     EDIT: Based on the first results and a quick glimpse at the references given, I would recommend:   The  looks like a bible. Everything seems to be included. It could be a bit more technical, but it gives a lot of bibliography to go deeper if necessary. , for lighting  and  for sensor technology  and the somewhat easier  for optics   Not to forget the , wonderful resource.

I am thinking about ordering up some parts for every day use. I am thinking about making one big purchase so as to minimize on shipping and other charges.   What are some of the components that any electronics hobbyist should have around ALL the time?  To put a little more scope: typically working with Arduino's, PICs and sensors. 5V - low current projects.   Looking for: component, value or range (if any), manufacturer (optional)   For example -  Resistors, 1K through 100K 5W

I'm interested in learning how to use geometry and topology in physics. Could anyone recommend a book that covers these topics, preferably with some proofs, physical applications, and emphasis on geometrical intuition? I've taken an introductory course in real analysis but no other higher math.

Though there are several posts discussing the reference books for topology, for example . But as far as I looked up to, all of them are for the purpose of learning topology or rather on introductory level.  I am wondering if there is a book or a set of books on topology like Rudin's analysis books, S.Lang's algebra, Halmos' measure (or to be more updated, Bogachev's measure theory), etc, serving as standard references.  Probably, such a book should hold characteristics such as being self-contained, covering the most of classical results, and other good properties you can name.  In the end, I only have the interest on general-topology (topological space, metrization, compactification...), and optionally differential topology (manifolds). So please don't divert into algebraic context.  Cheers.  ---------------------update-----------------------  Thanks for all the delightful replies. I will try to quickly check the books mentioned beneath. And I may accept the answer which is most closed to my personal flavor.  Sorry for others. It's a pity no multiple acceptance can be made for such a ref-request question.  Greetings.

I am trying to include a DC jack on one of my PCBs. I am just setting up the footprints now, and I am not quite sure which pin is which. What do the symbols on the drawing mean?  I have included a snap of the schematic below, it has been taken directly from the .
