Re: [Pharo-project] [COTDC] 59 - HierarchicalURI

by CÃ©drick BÃ©ler

part taken from URI class comment: "A hierarchical URI is either an absolute URI whose scheme-specific part begins with a slash character, or a relative URI, that is, a URI that does not specify a scheme. Some examples of hierarchical URIs are: http://www.pharo-project.org/home file:///~/calendar A hierarchical URI is subject to further parsing according to the syntax [scheme:][//authority][path][?query][#fragment] where the characters :, /, ?, and # stand for themselves. The scheme-specific part of a hierarchical URI consists of the characters between the scheme and fragment parts. The authority part of a hierarchical URI is, if specified, either server-based or registry-based. A server-based authority parses according to the syntax [user-info@]host[:port] where the characters @ and : stand for themselves. Nearly all URI schemes currently in use are server-based. An authority part that does not parse in this way is considered to be registry-based. The path component of a hierarchical URI is itself said to be absolute if it begins with a slash character ('/'); otherwise it is relative. The path of a hierarchical URI that is either absolute or specifies an authority is always absolute."

Re: [Pharo-project] Nile tests red - Pharo 1.3

> Keep on making Pharo, IMHO it's the best thing that happened to squeak since years - though I was very septic at the beginning > Last time I made a small demo to 2 of my collegues they didn't laugh - scouic - and were even impressed by smalltalk concepts Thanks *a lot* alain. we **know** what you think. We were teaching Smalltalk to students and look like idiots during years. I should be one of the person that demoed a *lot* smalltalk and got burned. I could impose Smalltalk in some places because of my strong large cv. As we already said we invested a lot in Squeak (I wrote three books = 4 years to write one) and a lot of things. For my job people were laughing: oh you are doing Smalltalk, little smile = you are an idiot while I'm the french which published the most in OOPSLA but this did not count..... and this was a problem for me to get a job. I can continue the long list like that. So doing pharo was not an easy decision: it was pharo or ruby or python or lua. I hope that we did not make the wrong choice - I'm not joking. Now for pharo we have a vision: We want a system to invent the next one and that people can make a living with it. - bootstrappable - clean lean robust - (ideally) good interface with C - (ideally) a lovely fast readable documentd extensible VM - good infrastructure - meta model for code - browser for remote/crosscompilation/default browsing - new compiler - first class instance variable - new network layer - new graphics - new module system At the end it may not be Smalltalk but it will be the same spirit. I think that we are slowly getting to the point where we will start to invent new things instead of just removing old experiences. Stef

Re: [Pharo-project] Popularity of Smalltalk in Software Industry

Hi While I agree with everyone's sentiments I think that practically If I ware starting my career off again I would still go into Java or .NET. To get a job as a Smalltalk developer is difficult simply because they are so scarce. Yes technically Smalltalk has design and philosophical merits but, for someone starting their career, a more mainstream language would be best. It is still too difficult to make Smalltalk do enterprise scale integration and there is a serious lack of libraries; something that the Java and .NET (even Ruby) world does not suffer from. i'm not saying That Smalltalk can't do these things but rather that it is more difficult to integrate with the outside world; it's ecosystem is small compared to the J2EE ecosystem. My advice would be to start off with Java or .NET and then when you've gained practical development experience (+-5 years) decide where you want to take your career. During this time you should be looking at other languages and practices, such as Smalltalk, software methodologies, DDD, FP etc, and learn from them to make you a better software engineer. A career in development is so much more than simply the programming language. BTW I'm still regretting not taking a Smalltalk position here in South Africa when I had the chance :) Maybe I will still...
