Mod Parent up! I have a well read copy of Effective C++ sitting within arms reach of my desk. Many projects have benefited from this book, I have team members who have "seen the light" due to Meyers thoughtful reasoning for his tips. Read effective C++, it is the best C++ tip book out there, it will save you days of debugging time in the long run.
I agree. The best advice from an experienced sys admin was to get UNIX SYSTEM Administration Handbook it has great examples of how to do the same task on BSD like unices vs ATTish distributions.
I am guessing most people use their VCRs as read only devices, I know I do. I haven't recorded anything on TV for the last ten years. People I know who record their favorite shows do so rarely. I would guess there isn't much of a market to start with for recording.
If you read the 1.0 manifesto you'll see that they are working to stabilize the API so additions like this can happen _without_ effecting schedule. That is the beauty of the mozilla, building new apps on the foundation of existing standard technology with XUL + your own XPCOMs. Is does not appear that the foundation will need to be changed for for the new application. XUL is good!
I know a gal who had a stamp that said RETURN TO SENDER, REMOVE FROM MAILING LIST"
She would stamp the junk mail without opening it, and this for about a year and the junk mail is almost zero now
100ms+ is for a full text search or database query that returns 100+ records that requires post processing takes at least that long. I would agree that CORBA is faster than SOAP for an echo, but for calls that take any sort of process time like a LDAP or DB query SOAP would come out in the wash, especially when the HTTP connection is kept open.
People from application server companies such as BEA recommend kepting the objects on the same server as the serverlets.
I'll have to check out OmniORB, thanks. What are the differences between calls that do processing other than echo?
Since many firewalls are setup to not allow CORBA ports so we have two ways of calling out search service, one via CORBA for intranet, and one via SOAP for internet.
I had the same feeling unit I tested the performance. Comparing SOAP/CORBA/RMI/DCOM/Vanilla RPC with network latency on a 100 baseT network SOAP performs just as good as any other remote object technology. All calls average around 100ms round trip.
With any remote call the following sequence need to occur:
marshal parameters on client
Open a socket to server
Receive / unmarshal params on the server
Create/invoke object
Marshal return values and write to socket
Unmarshal on the client.
Marshalling becomes negligible. Web servers and XML parser are being further optimized by the day. XML can be very efficiently parsed without creating a DOM using SAX checkout http://xml.apache.org. Combine an apache module with Xerces parser and you will have one fast socket listener (web server)/ marshaler(SAX parser) that is very easy to use.
Write some test code an you too will be a SOAP believer:-)
I am currently working on design for a multiplatform B2B 3D collaboration system and feel the block setting in frequently. Once a friend showed me God's desire to have a relationship with me on a day to day minute to minute basis. I was more likely to ask Him for help and peace, and boy does it come. God has since shown me over and over again He does care and is listening. BTW you can pray when you are getting exercise or drinking a beer too:-) It's free like freedom as well.

wondering why 1.0 is soooo far off?
