Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

clr cli .NETGeneral c# memory allocation

shared by Matteo Spreafico on 14 Aug 09 - Cached

Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.
...

Cancel
I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
...

Cancel
Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.

As long as the implementation maintains the semantics guaranteed by the specification, it can choose any strategy it likes for generating efficient code

That Windows typically does so, and that this one-meg array is an efficient place to store small amounts of short-lived data is great, but it’s not a requirement that an operating system provide such a structure, or that the jitter use it. The jitter could choose to put every local “on the heap” and live with the performance cost of doing so, as long as the value type semantics were maintained
...

Cancel
I would only be making that choice if profiling data showed that there was a large, real-world-customer-impacting performance problem directly mitigated by using value types. Absent such data, I’d always make the choice of value type vs reference type based on whether the type is semantically representing a value or semantically a reference to something.

symbian Open source Cellular phones PDA S60

shared by David Corking on 11 May 09 - Cached

In this regard, SymbianOS may have a leg up on Apple's App Store and even Nokia's Ovi Store, in that the "Symbian Application Inventory" will be free for developers. That's what you call "incentive," but is it enough?
- David Corking on 11 May 09
  
  Before it attracts app developers, it has to attract hardware integrators. There is plenty of hardware out there, but isn't this selling in far lower volumes than Linux or the proprietary smartphone OSes. As far as I can tell, it has attention from the biggest smartphone integrator of them all: Nokia, who, as far as I can tell, uses it in the best selling N95 family. This ratchets up the competion with Apple and RIM another notch.

This Symbian system (aka Psion and Nokia S60) was well loved for its well though out personal organizer or PIM applications. Now, smartphone users seems more interested in e-mail, music and games. I am interested to see if Symbian OS still has a profitable niche. Symbian is a market leader in the new market.

My comment above might imply that Smalltalk is not modern. The truth is far from it, as Smalltalk is still pushing the boundaries of technology and user interfaces, from Croquet and Qwaq, to Alice, Sophie, Scratch and Etoys.

(I fixed Friday's broken link to the PDF.) From what I read so far, this seems to be another attempt at a fully introspecitve integrated and customisable personal computer with a graphical desktop. In other words, it is Dynabook Smalltalk and Lisp workstations all over again, but quite likely with some interesting modern twists.

It is always important to know how to submit a bug report. It doesn't help that every community has different expectations, and every bug tracking system has a different layout. In Squeak, the learning curve is long but shallow. In this 23 minute screencast, Ken Causey starts with some bug hunting tips, and explains how to make a Smalltalk changeset file that is numbered, documented and compressed. He then shows how to submit this to the Mantis server on bugs.squeak.org.

Again, we augment Function. We make an instance of the parent class and use it as the new prototype. We also correct the constructor field, and we add the uber method to the prototype as well.

This adds a public method to the Function.prototype, so all functions get it by Class Augmentation. It takes a name and a function, and adds them to a function's prototype object.

To make the examples above work, I wrote four sugar methods. First, the method method, which adds an instance method to a class. Function.prototype.method = function (name, func) { this.prototype[name] = func; return this; };

JavaScript can be used like a classical language, but it also has a level of expressiveness which is quite unique. We have looked at Classical Inheritance, Swiss Inheritance, Parasitic Inheritance, Class Augmentation, and Object Augmentation. This large set of code reuse patterns comes from a language which is considered smaller and simpler than Java.
...

Cancel
I have been writing JavaScript for 8 years now, and I have never once found need to use an uber function. The super idea is fairly important in the classical pattern, but it appears to be unnecessary in the prototypal and functional patterns. I now see my early attempts to support the classical model in JavaScript as a mistake.

You can also send out your tweets. If people like your tweets, they will begin to “retweet” them to their own followers, some of whom will choose to follow you, too. In a very short time, you can build up an amazing network of people involved in your area. A tweet I did last week was retweeted by four people (there is software that helps you track your retweets). The total number of followers came to more than 5,000. So my one tweet went out to more than 5,000 people around the world, most of them interested in the same area as me.
