• How do you choose a programming/data structure/algorithm book?

  - by Fanatic23

  I really should not be mentioning the name of the book, but the first time I read it (during my under-grad days) I almost concluded that data structure was a bad course to pick. Which brings me to the question I am asking here. What makes a programming or data structure or algorithm book tick? Clearly, lucid explanation is one. But I also realize that organization of the material is very important and so is diagrams. What else? Some pointers would obviously help when I hang out in my neighborhood computer book shop the next time.

• Is there a single book that covers the breadth of computer science fundamentals? [closed]

  - by superFoo

  When I did my undergraduate studies in elecrical engineering, there was this book called "Basic Electricity" by Van Valkenburgh. If you read that book cover to cover, your fundamentals in electrical engineering would be bulletproof. I would recommend it all my juniors and I absolutely loved it. Is there such a book in the field of computer science? I am not so concerned about the algorithms. I am looking more into something that tells me how does everything work beneath the covers. TCPIP, memory management, DNS, routing, SSL, buffer, queuing etc.

• Return Selected Phone Address from iPhone Address Book

  - by Ali

  Hey, I found a tutorial online that extends that Apple QuickStart Application which is the basic Address Book Application and another that returns the first phone number regardless of what phone number was clicked. I want to display only the selected phone number in the label. The label is called phoneNumber: - (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{ ABMutableMultiValueRef phoneMulti = ABRecordCopyValue(person, kABPersonPhoneProperty); NSMutableArray *phones = [[NSMutableArray alloc] init]; int i; for (i = 0; i < ABMultiValueGetCount(phoneMulti); i++) { NSString *aPhone = [(NSString*)ABMultiValueCopyValueAtIndex(phoneMulti, i)autorelease]; [phones addObject:aPhone]; } NSString *mobileNo = [phones objectAtIndex:0]; self.phoneNumber.text = phones; [self dismissModalViewControllerAnimated:YES]; return NO; } How do I ensure that the label is the one selected by the user and not just the first array entry(or any other array entry i code in) Thanks

• SyntaxError using gdata-python-client to access Google Book Search Data API

  - by isbadawi

  >>> import gdata.books.service >>> service = gdata.books.service.BookService() >>> results = service.search_by_keyword(isbn='0434003484') Traceback (most recent call last): File "<pyshell#4>", line 1, in <module> results = service.search_by_keyword(isbn='0434003484') ... snip ...

I've looked at the wiki and open issue tickets on Google Code to no avail (and this seems to me more apt to be a silly error on my end rather than a problem with the library). I'm not sure how to interpret the error message. If it matters, I'm using python 2.6.5.

• Good Economics book for developers

  - by Rocket Surgeon

  Joel mentions in several of his blog posts that it is very important for a developer/software entrepreneur to have solid understanding of Economics. Yet the Fog Creek MBA book reading list does not include any Economics books. Is there any good material that people can recommend? Obviously, I am not as concerned about mathematical treatise as foundations and basic principles. For example, I was able to find a very good high-level read on Macroeconomics: Concise Guide to Macroeconomics but I am yet to find anything similar on Microeconomics. Any suggestions and reading pointers would be highly appreciated.

• Best practices book for CRUD apps

  - by Kevin L.

  We will soon be designing a new tool to calculate commissions across multiple business units. This new compensation scheme is pretty clever and well thought-out, but the complexity that the implementation will involve will make the Hubble look like a toaster. A significant portion of the programming industry involves CRUD apps; updating insurance data, calculating commissions (Joel included) ...even storing questions and answers for a programmer Q&A site. We as programmers have Code Complete for the low-level formatting/style and Design Patterns for high-level architecture (to name just a few). Where’s the comparable book that teaches best practices for CRUD?

• Getting started with modern software architecture and design using a book

  - by bitbonk

  I am a rather oldschool developer with some basic knowledge of software design principles and a good background on classic (gof) design patterns. While I continue my life as such I see lots of strange buzzwords emerge: Aspectoriented Design, Componentoriented Design, Domain Driven Design, Domain Specific Languages, Serviceoriented (SOA) Design, Test Driven Design, Extreme Programming, Agile Development, Continuous Integration, Dependency Injection, Software Factories ... Is there good book around that I can take with me on a roadtrip while it is taking me on a trip through all (most) of the above, delivering an 10,000 foot view on modern software archiceture and desing principles and approaches.

• Rails 2.3.4 Vs Rails 3 + Book - Beginner in RoR

  - by zengr

  Hi, I have started with Ruby and Rails development and I am a Java developer from the last 2 years (student). I am in for two things: Learn Ruby Make my website on ROR I have Agile Web Development with Rails, 2nd Edition. So, here are my questions: How is the Agile Web Development with Rails book to start with, where I don't know anything about Ruby and proficient with Java. What is the difference between 2nd and 3rd edition? People say the changes are irrelevant for a starter, how far is that statement correct? Should I start with Rails 2.3.4 or Rails 3 (around the corner)?

• Flash AS3 Coloring Book - Movieclip only clickable in certain spots (Event Listeners)

  - by kilrizzy

  I am working on a coloring book and have a movieclip (outlines) containing many movieclips that can be changed to whatever color the user has selected. However it seems like some of the movieclips can be clicked anywhere and work great, and others you need to click a certain spot for it to color in. I have an example here: http://jeffkilroy.com/hosted/softee/coloring.html Notice the three sections of the icecream (top, middle, bottom). The middle is clickable from anywhere inside the movieclip, however the top and especially bottom require you to click on specific spots in order for you to activate the event listener. Not sure if it is a depth issue because I would assume if that is the case it would activate at least a different movieclip but it just seems nothing happens at all. Any help would be appreciated, I also have the source located here: Source CS4 Source CS3

• Silverlight 3-4 reference kind (e-)book.

  - by Bubba88

  Hello! I'm looking for a source of information about Microsoft Silverlight to begin practically efficient programming custom functionality applications. I want to pretend just for now that I don't need any ideologically correct refresher (SL tips, top patterns, VS tutorials :) and etc.). Basically, what I want is a reference kind e-book, where I could find any practically relevant info outlined in a minimalistic manner. If you do remember something fitting the above description, I ask you to give me a hint. Thank you very much!

• What would you like to see in an beginner's ASP.NET security book

  - by blowdart

  This is a shameless information gathering exercise for my own book. One of the talks I give in the community is an introduction to web site vulnerabilities. Usually during the talk I can see at least two members of the audience go very pale; and this is basic stuff, Cross Site Scripting, SQL Injection, Information Leakage, Cross Site Form Requests and so on. So, if you can think back to being one, as a beginning web developer (be it ASP.NET or not) what do you feel would be useful information about web security and how to develop securely? I will already be covering the OWASP Top Ten (And yes this means stackoverflow will be in the acknowledgements list if someone comes up with something I haven't thought of yet!) It's all done now, and published, thank you all for your responses

• Book recommendation for learning server management and Apache

  - by japancheese

  Hello, I'm currently managing a site that I feel could be optimized and utilized to be much faster, however, I'm having difficulty finding reliable information to do it. I find the Apache documentation to be a hard read, and too technical about things I don't have a strong grasp on. I'm just looking for a good beginner/intermediate book about server administration to learn as much as possible about Apache, as well as how to create a nice secure, robust server that doesn't crash at the first hint of unusual traffic surges. Thanks to anyone who can point me in the right direction.

• counting number of new entries in guest book

  - by Lucka

  I want to display the number of new(unseen) guest entries in the guest book of a user. I was thinking to count it so that, total number of entries in guestbook minus entries in guestbook at time of last login. However, I think that is not a good approach, because if the user logs in but does not go to his guestbook, in that case, the entries should be still "new", also if some new entry is posted in the user while he is online, it does not work in that case too. Any suggested please?

• Get a random name and number (same contact) from an iPhone users address book

  - by Sam Jarman

  Hi there, I have had only very little experience using the address book in the iPhone SDK. Does anyone have a code snippet or knows the code to get a persons name and number Eg 'Fred Smith - 027 292 2112". I haven't had much luck with the stuff I've tried. I want to achieve this programmatically, and not let the user decide (random pick of the person). I also don't want to display the contact picker either any tutorial links, or anything would be appreciated. Thanks in advance Sam

• O'Reilly book clarification on 2d linear system

  - by Eric

  The Oreilly book "Learning openCV" states at page 356 : Quote Before we get totally lost, let’s consider a particular realistic situation of taking measurements on a car driving in a parking lot. We might imagine that the state of the car could be summarized by two position variables, x and y, and two velocities, vx and vy. These four variables would be the elements of the state vector xk. Th is suggests that the correct form for F is: x = [ x; y; vx; vy; ]k F = [ 1, 0, dt, 0; 0, 1, 0, dt; 0, 0, 1, 0; 0, 0, 0, 1; ] It seems natural to put 'dt' just there in the F matrix but I just don't get why. What if I have a n states system, how would I spray some "dt" in the F matrix?

• Getting started with Qt4: which book to read?

  - by Pieter

  I'm trying to learn Qt4. I have written code in C, C#, Python, PHP, Java and JavaScript before, but not in C++. Is there a book on Qt4 that you can recommend me? I've found some books I might like, but they're a little on the expensive side. I'm not ready to commit to Qt before I've played with it for a while, so I'd prefer to keep it under 30 bucks. I will accept the answer that gets the most up votes.

• What's a good book for learning BCPL?

  - by paxdiablo

  A long time ago, I worked on some BCPL code (very similar to C although even more basic, difficult though that is to imagine). Now, as part of a compiler course, we're going to be setting assignments for building some of the parts of the compiler (lexical and semantic analysis) and I'd like to know what the community thinks is the best book for learning about the language (and concrete why you think it's the best). Not how to write compilers for it, just on how to program in it. It'll be up to the students themselves to figure out how best to develop a compiler. We're using BCPL since the chance of people being able to plagiarise code for a compiler is very slim. Any suggestions?

• Normalising book titles - Python

  - by RadiantHex

  Hi folks, I have a list of books titles: "The Hobbit: 70th Anniversary Edition" "The Hobbit" "The Hobbit (Illustrated/Collector Edition)[There and Back Again]" "The Hobbit: or, There and Back Again" "The Hobbit: Gift Pack" and so on... I thought that if I normalised the titles somehow, it would be easier to implement an automated way to know what book each edition is referring to. normalised = ''.join([char for char in title if char in (string.ascii_letters + string.digits)]) or normalised = '' for char in title: if char in ':/()|': break normalised += char return normalised But obviously they are not working as intended, as titles can contain special characters and editions can basically have very different title layouts. Help would be very much appreciated! Thanks :)

• Unable to import example projects from book (newbie question)

  I am trying to import projects from a book "Beginning Android 2" but when I choose the root directory the "Finish" button is still grayed out. I've tried importing the project from scratch with no success, and I've also tried to create a template project with the same name and everything and then importing into that (Import existing projects into workspace) but it always says "No projects are found to import". The contents of the folder are: Res folder, src folder with .java file, the manifest, build, and default.properties files. I am new to android dev (obviously) so I appreciate the help.

• Best .Net/C# book for an interview

  - by DrunkenBeard

  Hi, I'm having an interview for an internship in the coming days and would like to know if there are any books that are particulary suited for preparing interviews. The interview is not particulary hard, just some questions about .Net and C# plus an algorithm to code. I tried C# in a Nutshell but it goes in too much detail for what I want to achieve. I'm more looking for a good yet small book that explains the important concepts of the .Net framework and C#, I already know the details, just want formal explanations so I'm confident when answering. Thanks :)

• Looking for a good course/book/resource on modern databases

  - by spanky

  This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.
