Does anyone have any tips for getting a good price on new/used programming-related books? I've looked at some of the more popular books (like DDD and GoF), and even used they can be pretty pricey. I'm not saying they aren't worth it, but I feel like there might be a more focused book store or exchange or something just for devs and/or ...
Do you know if there is anything out there like Chilton's for cars for programming quotes: http://chilton.cengage.com/ Looking for a programming book or sites that may be like it, or about process. I am trying to get a better grip on quoting jobs and wondering if there is anything like this. ...
Maybe this is a compiler specific thing. If so, how about for gcc (g++)? If you use a variable reference/alias like this: int x = 5; int& y = x; y += 10; Does it actually require more cycles than if we didn't use the reference. int x = 5; x += 10; In other words, does the machine code change, or does the "alias" happen only at the ...
Iam new to iphone development and have been tasked to development a fairly simple iphone application. It would basically show listings of information eg accommodations, restaurants...around 8-9 different types. Drilling on one would show the details of it. These are dynamically sourced from a db (through an xml feed) that powers an exi...
The title says it all. Imagine I have two (three, four, whatever) tasks that have to run in parallel. Now, the easy way to do this would be to create separate threads and forget about it. But on a plain old single-core CPU that would mean a lot of context switching - and we all know that context switching is big, bad, slow, and generally...
Hopefully this question is allowed over here. It does not really have to do with programming per se but with the costs associated with it. My question is: "How much does sending/receiving XMPP messages cost". I can find all the information about email etc. But I could not find information about costs sending/receiving XMPP mess...
Hi, Is there any formula showing the development cost of an application? Basically not to reach a very specific number but at least stressing what parts are effecting the overall cost in what magnitude? Thanks, burak ozdogan ...
I believed any kind of asynchronous execution makes a thread in invisible area. But if so, Async codes does not offer any performance gain than threaded codes. But I can't understand why so many developers are making many features async form. Could you explain about difference and cost of them? ...
I'm interesting in the time cost on a modern desktop CPU of some floating point operations in order to optimize a mathematical evaluation. In particular I'm interested on the comparison between complex operations like exp, log and simple operation like +, *, /. I tried to search for this information, but I could't find a source. What ...
My employer is asking for details about the MS PDC conference that is taking place later this year. I know there are no official details available to the public yet so I am looking for estimates based on previous year's registrations. What is a good ballpark estimate on how much it will cost to attend PDC 2010? ...
I always had trouble with estimating cost/price of finished software (or programming work), so here are two questions about it. question 1: You're asked to write a piece of code for cash (all rights to the code belongs to buyer once you're done). You know approximate number of hours it will take (+-25%), and approximate complexity (i....
Taking the following snippet as an example: struct Foo { typedef int type; }; class Bar : private Foo { }; class Baz { }; As you can see, no virtual functions exist in this relationship. Since this is the case, are the the following assumptions accurate as far as the language is concerned? No virtual function table will be creat...
From what I've understood, App Engine indexes are costly both in terms of increased overall storage size and by slowing down your writes. But do indexes only cost when they're actually used in queries and are explicitly defined in index.yaml? Or do properties such as StringProperty cost more than their non-indexed counterpart (e.g. Text...
I am doing the unifrom cost search algorithm. I am getting my solution slightly larger than actual. The number of expanded nodes are coming larger than actual. I used this algorithm: Get the initial node and put it into the priority queue.The P.queue will itself arranges the nodes in it according to the cost. Lower cost node will come ...
Does anyone have any thoughts on how much to charge for release copyright on an iPhone app I'm building for a client? I have a reasonable idea of how much I should charge for the app development, but I never release copyright on anything I do for clients. Thanks! ...
How much does it cost to run a social network on average in terms of hardware and bandwidth per user, with a Ruby on Rails average stack? ...
Rich sites such as facebook send you an email for every event that takes place, notification, friend request and so on, I would like to know how costly is it for the web server to perform this action? that also 100s of time a day for active and popular users. Thanks ...
I'm trying to explain the ratio of development versus maintenance costs to our sales department, and currently I have mostly my gut feeling that we spend about 60% of the time with maintenance. We have some persons on the team who tends to sell custom solutions, that we have to build, and if the sales people doesn't understand the total...
Not sure where to put this but a site filled with working programmers is a good bet. I built a website for a client, that included (on the home page) a fancy jQuery image slider with controls. This was specified in the original project scope. I also implemented a simple jQuery slider on one of the inner pages. Now that the site is up f...
Hey guys this is one of the non Technical questions I can say but very important in terms of charging for software development. Recently I have been offered a freelancing project on ASP.net from one my known friends. Please try to help me cos I am new to freelancing and I really dunno how much to quote for the project. Also this is my f...
