• Looking for programs on audio tape/cassette containing programs for Sinclair ZX80 PC?

  - by DVK

  OK, so back before ice age, I recall having a Sinclair ZX80 PC (with TV as a display, and a cassette tape player as storage device). Obviously, the programs on cassette tapes made a very distinct sound (er... noise) when playing the tape... I was wondering if someone still had those tapes? The reason (and the reason this Q is programming related) is that IIRC different languages made somewhat different pitched noises, but I would like to run the tape and listen myself to confirm if that was really the case...

• How to sketch out an event-driven system?

  - by Jordan

  I'm trying to design a system in Node.js (an attempt at solving one of my earlier problems, using Node's concurrency) but I'm running into trouble figuring out how to draw a plan of how the thing should operate. I'm getting very tripped up thinking in terms of callbacks instead of returned values. The flow isn't linear, and it's really boggling my ability to draft it. How does one draw out an operational flow for an event-driven system? I need something I can look at and say "Ok, yes, that's how it will work. I'll start it over here, and it will give me back these results over here." Pictures would be very helpful for this one. Thanks. Edit: I'm looking for something more granular than UML, specifically, something that will help me transition from a blocking and object-oriented programming structure, where I'm comfortable, to a non-blocking and event driven structure, where I'm unfamiliar.

• Where is a good place for a code review?

  - by Carlos Nunez

  Hi, all! A few colleagues and I created a simple packet capturing application based on libpcap, GTK+ and sqlite as a project for a Networks Engineering course at our university. While it (mostly) works, I am trying to improve my programming skills and would appreciate it if members of the community could look at what we've put together. Is this a good place to ask for such a review? If not, what are good sites I can throw this question up on? The source code is hosted by Google Code (http://code.google.com/p/nbfm-sniffer) and an executable is available for download (Windows only, though it does compile on Linux and should compile on OS X Leopard as well provided one has gtk+ SDK installed). Thanks, everyone! -Carlos Nunez

• What about Programmer "Invisible" registers?

  - by claws

  These are "Programmer Visible" x86-64 registers: What about the invisible registers? Just now I learned that MMU registers, Interrupt Descriptor Table (IDT) uses these invisible registers. I'm learning these things in the hard way. Is there any resource (book/documentation/etc) that gives me the complete picture at once? I am aware of the programmer visible registers and comfortable in programming with them. I just want to learn about invisible registers and their functionality. I want to get a complete picture. Where can I get this info?

• javaEE application layout

  - by arthurdent510

  I've been tasked with writing a new webapp in javaEE, which will be a first for me. I'm familar with the java language, but all of my previous projects have been in .net. So I've downloaded netbeans and I'll probably be using Hibernate, and started digging in. My question is, what's the best way to lay out a javaEE app? Should all data access go through netbeans? I was told to use webservices as much as possible so it's easy to pull data in and out of the system, and I've read through tutorials that create webservices in a seperate web application, as compared to the javaEE enterprise application. Is that really the way it's supposed to work? Just trying to wrap my head around this as compared to what I'm used to in .net. Thanks!

• Dns.GetHostEntry returns multiple IP addresses

  - by spender

  This question probably highlights a lack of understanding of networking principals on my part, rather than a programming issue. I'm doing a lookup on a hostname using Dns.GetHostEntry This returns an IPHostEntry to me, which has an AddressList property which is an array of IPAddress. I always thought there is a 1 to 1 mapping between hostname and IP, but I'm finding that in some cases I get back several IPAddress(es) for the same host. This is a surprise to me. Which part of domain name resolution do I not understand?

• Probability Homework Help

  - by Alon

  A child is tasting two types of chocolate. The probability that he will like the first type if he liked the second type is 5/6. The probability that he will like the second type if he liked the first type is 3/8. It is known that the probability that the child won't like the second type of chocolate is doubled than the probability that he won't like the first type. What is the probability that the child like at least one of the two type of chocolates? So I tried: 1-[P(not like the first type AND not like the second type)] which is like: 1-[P(not like the first type)*P(not like first type / not like the second type) + P(not like the second type) which equals: P(not like first type / not like second type) But now, I don't have the data of the conditional probability. In addition, I'd like to see how could it solved using a computer programming language. Any ideas? Thank you.

• How do I automate navigation to a website that requires authentication?

  - by Wiz

  Here's what I'm trying to achieve. I would like to write a script that will navigate to a website that requires me to be authenticated as myself, say Facebook, Live Spaces, Twitter or any other, and then have that script search for certain information on one of the pages of the website. I've done something similar in the past with the Windows.Forms WebBrowser control, which is a full blown implementation of IE that can be controlled through code and will store whatever cookies you get once you're authenticated, but it was very unfriendly to modify and I was hoping to use a scripting language instead, maybe Powershell or something of that sort. Are there maybe some good tutorials about this out there on the web? Thanks!

• Limit a program's execution time in C (Monte Carlo technique)

  - by rrs90

  I am working on a project which has no determined algorithm to solve using C language. I am Using Monte Carlo technique for solving that problem. And the number of random guesses I want to limit to the execution time specified by the user. This means I want to make full use of the execution time limit defined by the user (as a command line argument) to make as many random iterations as possible. Can I check the execution time elapsed so far for a loop condition. Eg: for(trials=0;execution_time P.S. I am using code blocks 10.05 for coding and GNU compiler.

• Getting started with Windows Azure

  - by jonhobbs

  Hi All, I'm going to sound like a complete newbie here but here goes... I've just signed up for a Windows Azure account and was hoping to get a simple hello world aspx page up and running in a browser to see how it all works but I can't seem to find a simple guide to getting a very simple web application running. I've got as far as setting up a "service" and going onto the "deploy" page but it's asking me upload an "application package". I've looked on MSDN but there aren't any simple guides, just reams of documentation talking about "roles" and "development fabric". For somebody that is proficient in HTML/CSS and knows a little abit about asp.net it may just as well be in another language. So, does anybody know how to upload a simple aspx page and then access it in a browser? Jon

• COMET with [Session ] TimeOut

  - by Amitd

  hi guys, Just Wondering how [Session] timeouts are(or can be) implemented when using Comet? I'm using Long polling Comet solution and want to implement a kind of Timeout feature. Example : If the user is on a Comet enabled page and doesn't respond to server events/notification for a period of time say 10 mins then invalidate his session and remove his request from server and redirect the user to a timeout page? Will this require Javascript XHR requests to check for a timeout explictly? Using ASP.NET 3.5 / C# (Doesn't need to be language specific) Thanks

• reading a BYTE as a DWORD in Masm

  - by Help I'm in college

  Hi, once again I'm doing MASM programming. I'm trying to write a procedure using the Irvine32 library where the user enters a string which is put into an array of BYTEs with ReadString. Then it loops over that arrray and determines if each character is a number. However, when I try cmp [buffer + ecx], 30h MASM complains about comparing two things that are not the same size. Is there anyway I could read the ASCII code in each BYTE in the array as a DWORD (or otherwise extract the ASCII value in each BYTE)?

• What is C's analogy to LabVIEW's Event Structure?

  - by SiegeX

  One programming construct I use quite a bit in LabVIEW is the Event Structure. This gives me the benefit of not having to needlessly waste CPU cycles via polling but only perform actions when an event I'm interested in is generated. As an experienced LabVIEW programmer with a decent understanding of C, I'm curious how one would go about emulating LabVIEW's event structure in C; preferably under Linux. A small code sample (like the one in the link above) illustrating how this might be done would be much appreciated. Also, if there already exists 3rd party libraries (for Linux) to add this event framework to C, that would be nice to know as well. Thanks.

• Reusable socket

  - by Andrew

  I tryed to create a socket in php and reuse it from other process. I know this can be done with a daemon script but I want to do this without. I created a socket and binded it to a specific port. $sock = socket_create (AF_INET, SOCK_STREAM, SOL_TCP); socket_set_option ($sock, SOL_SOCKET, SO_REUSEADDR, 1); socket_bind ($sock, 'xx.xx.xx.xx', 10000); socket_connect ($sock, $host, $port); And from another php file I did the same thing. But the packets that I send from the 2 file are not "validated" by host. I sniffed all ports and I see that it uses same local and destination port. I don't understand where is the problem. Can you help me with this? It's ok in any other programming language, or any other solution for this. Andrew

• Looking for evolutionary music example code

  - by Dan Dyer

  I would like to implement an interactive evolutionary algorithm for generating music (probably just simple melodies to start with). I'd like to use JFugue for this. Its website claims that it is well-suited to evolutionary music, but I can't find any evolutionary examples. I already have a framework to provide the evolutonary machinery. What I am looking for is some simple, working code that demonstrates viable approaches for the musical part (e.g. suitable encodings and evolutionary operators for the evolved tunes). I have some ideas how it might be achieved, but I'm not particularly knowledgeable about music theory, so to start with I'd like to just reimplement something that is known to work. So does anybody have, or know of, any freely available code (any language is fine) that demonstrates one or more approaches to evolutionary music? EDIT: I'm specifically looking for evolutionary code rather than other techniques that could be used for music synthesis.

• newbie question -- how does one override show for a newtype?

  - by gatoatigrado

  I want to override the default integer constructors in Haskell so they produce strings (mostly for curiosity, but temporarily to make a nice input alternative for LaTeX's \frac{}{} inconvenience). I wanted to be able to use the language itself, instead of a special parser, but I guess that's probably not going to work out... module Main where import Prelude hiding ((+)) newtype A = A Int deriving (Eq, Show, Num) default (A) (+) :: A -> (A -> String) (A a) + (A b) = (show a) ++ " + " ++ (show b) main2 = 3+4 main :: IO () main = putStrLn main2 The problem with the above is that the + function only works for (A, A) instead of (A, String), etc. If one simply leaves out the pattern match "(A a)" and writes "a" instead, then the show() function prepends "A " so "3" becomes "A 3" instead of just "3". I want to override Show for A, but it seems to be quite a headache...

• How to incorporate WebSockets into a Cocoa application

  - by robw

  I am developing a Cocoa application which involves a chat element. One approach I've considered is using Websockets to handle client-server communication. This would be particularly desirable because chats will also be displayed on a website, and using Websockets could make the implementation very simple. So: would it be possible to use a WebView element, and use Websockets within it? (I know Safari doesn't support Websockets yet, so I imagine this is not possible?) Failing that, are there any Websocket client libraries for C, Objective C, or any other language I could successfully embed within my application? Suggestions welcomed.

• Can compiler optimization introduce bugs ?

  - by ereOn

  Hi, Today I had a discussion with a friend of mine and we debated for a couple of hours about "compiler optimization". I defended the point that sometimes, a compiler optimization might introduce bugs or at least, undesired behavior. My friend totally disagreed, saying that "compiler are built by smart people and do smart things" and thus, can never go wrong. He didn't convinced my at all, but I have to admit I lack of real-life examples to strengthen my point. Who is right here ? If I am, do you have any real-life example where a compiler optimization produced a bug in the resulting software ? If I'm mistaking, should I stop programming and learn fishing instead ? Thank you !

• Clob as param for PL/SQL Java Stored Procedure

  - by JDS

  I have a java stored procedure that takes in a clob representing a chunk of javascript and mins it. The structure of the function calling the JSP is as follows: function MIN_JS(pcl_js in clob) return clob as language java name 'JSMin.min(oracle.sql.CLOB) return oracle.sql.CLOB'; In the actual JSP, I have the following: import oracle.sql.CLOB; public class JSMin { ... public static min(CLOB js) { ... } The problem I'm having is that whenever I pass a clob to JS_MIN, it is always interpreted as null inside the JSP. I've checked the clob before calling JS_MIN annd it definitely has contents. Any ideas as to what I'm missing? Any help is greatly appreciated.

• Flex - How to call a webservice without crossdomain.xml file

  - by Stephane Grenier

  How can I consume a webservice that hasn't explicitely created a crossdomain.xml? I understand it's for security and to prevent cross-site scripting, but it does seem like a major limitation to the Flex framework. For example, if I want to consume a webservice, which is suppose to be language agnostic, then I can't with Flex. The webservice/server has to be specifically prepared for Flex/Flash. If it's not, then it cannot be consumed. That can't be right can it?

• How do I change the background color of the column with the expanders in Eclipse?

  - by Pridkett

  Recently after scorching my retinas from the garish white background in Eclipse, I found some of the excellent posts about how to change the colors so it uses sane (i.e. dark background) colors in the editor. However, one problem present in all solutions is that background of the column with the expanders for code folding is always white. Is there a way to change the background of that column? Here's a screenshot of the problem: I'm not the only person that has this problem, as shown in the screenshots for the following questions: Dark Color Scheme for Eclipse Color Themes for Eclipse (application of color schemes results in this issue on a Mac, no idea about PC) I know that the problem is not language specific as it happens in Java, Python, HTML, and everything else. Any hints on where in the pages of preferences this setting is?
