• I'm looking for a better solution on importing catalog data into Adobe InDesign

  - by John Thompson

  The last time I produced a catalog I used a software called EasyCatalog that worked with Adobe InDesign to merge data from a spreadsheet with graphics. I wouldn’t say it was completely successful. I know of one other catalog building software called Catalog Builder by Computer Pundits. I'm just looking for any suggestions from someone who might have gone through this process on what software I should use.

• Memory layout of executable

  - by Ross

  Hi all, When loading an executable then segments like the code, data, bss and so on need to be placed in memory. I am just wondering, if someone could tell me where on a standard x86 for example the libc library is placed. Is that at the top or bottom of memory. My guess is at the bottom, close to the application code, ie., that would look something like this here: --------- 0x1000 Stack | V ^ | Heap ---------- Data + BSS ---------- App Code ---------- libc ---------- 0x0000 Thanks a lot, Ross

• While Mouse press event. Prototype JS or Javascript

  - by nahum

  Hi, I would like to know if someone knows how to make a function repeat over and over while the mouse is press, I don't know how to make it work. I know in prototype you can take events like $('id').observe("click",function(event){}) $('id').observe("leave",function(event){}) $('id').observe("change",function(event){}) //etc... but is something like $('id').observe("whilemousepress",function(event){}) :P //I know there is not any event in javascript but I would like to emulate. thanks...

• Linked List Design

  - by Jim Scott

  The other day in a local .NET group I attend the following question came up: "Is it a valid interview question to ask about Linked Lists when hiring someone for a .NET development position?" Not having a computer sciense degree and being a self taught developer my response was that I did not feel it was appropriate as I in 5 years of developer with .NET had never been exposed to linked lists and did not hear any compeling reason for a use for one. However the person commented that it is a very common interview question so I decided when I left that I would do some reasearch on linked lists and see what I might be missing. I have read a number of posts on stack overflow and various google searches and decided the best way to learn about them was to write my own .NET classes to see how they worked from the inside out. Here is my class structure Single Linked List Constructor public SingleLinkedList(object value) Public Properties public bool IsTail public bool IsHead public object Value public int Index public int Count private fields not exposed to a property private SingleNode firstNode; private SingleNode lastNode; private SingleNode currentNode; Methods public void MoveToFirst() public void MoveToLast() public void Next() public void MoveTo(int index) public void Add(object value) public void InsertAt(int index, object value) public void Remove(object value) public void RemoveAt(int index) Questions I have: What are typical methods you would expect in a linked list? What is typical behaviour when adding new records? For example if I have 4 nodes and I am currently positioned in the second node and perform Add() should it be added after or before the current node? Or should it be added to the end of the list? Some of the designs I have seen explaining things seem to expose outside of the LinkedList class the Node object. In my design you simply add, get, remove values and know nothing about any node object. Should the Head and Tail be placeholder objects that are only used to define the head/tail of the list? I require my Linked List be instantiated with a value which creates the first node of the list which is essentially the head and tail of the list. Would you change that ? What should the rules be when it comes to removing nodes. Should someone be able to remove all nodes? Here is my Double Linked List Constructor public DoubleLinkedList(object value) Properties public bool IsHead public bool IsTail public object Value public int Index public int Count Private fields not exposed via property private DoubleNode currentNode; Methods public void AddFirst(object value) public void AddLast(object value) public void AddBefore(object existingValue, object value) public void AddAfter(object existingValue, object value) public void Add(int index, object value) public void Add(object value) public void Remove(int index) public void Next() public void Previous() public void MoveTo(int index)

• Framework for iPhone wait screens

  - by 4thSpace

  I ran across a small framework some time back that someone put together for iPhone wait screens. But now I can't find any trace of it. Does anyone have a link to it? It may not be a framework as much as a few code snippets. But the guy had it all pre-made. You just needed to implement and specify the type of wait screen you wanted.

• How to implement mib module in net-snmp with python?

  - by Tom Carly

  Hi, in the faq, i read this "..the agent can also support MIB modules implemented in perl or (from 5.4) python." I have built net-snmp with python support, but it's not clear yet how to actually implement my own MIB module with python now. The python scripts i see in the python directory are related to implementing an snmp client, not an snmp agent. Probably i just miss the point somewhere. Can someone give me a hint on how to get started with this? Thanks, Tom

• iphone, get the object count without performing a fetch?

  Hi, I seem to recall that it's possible to return the resulting object count from an NSPredicate in CoreData without actually performing a fetch, but I can't find any reference to this. Can someone confirm that I wasn't dreaming (sad dream to have!), and would this be safe to do in another thread? Thanks Andy
