Adam Ralph has a list of the probable C# 6.0 features Mads Torgersen covered at new Developers Conference() NDC 2013 in London.
I thought it would be fun to show some before and after syntax for comparison and in doing so ended up with a few thoughts and questions. "Reply hazy try again"

I'm still learning C# so don't understand some of that, but the "Monadic null checking" seems like a pretty neat feature.

So I must be the only person on the world that thinks it's less readable and not that usefull...

I'm a bit meh on the syntax, I'd've preferred something like:
var bestValue = points.FirstOrDefault().X ??? -1;
Where the ??? operator would handle a null at any point in the object tree; but the option they chose is a bit more flexible and I suppose there are some cases where in A.B.C if B is null you might want a different behavior than if A or C are. Can't think of any, but I'm sure they exist.

Yeah, but it doesn't let you specify a default value, does it?
Well, i guess i could write A?.B ?? -1, but does that make it more readable? I personally prefer less operators.
|
|
|
|
|
Yes it does. The -1 at the end of the line in my ??? proposal and in MS's implementation are both the default value.

I see, I didn't notice the -1 on my first read.

It may be less readable to the uninitiated but it's more concise and its use will lead to less coding errors.

you sure it wont lead to a replacement of the dot?

Last month Windows 7’s growth outpaced that of Windows 8.x by four fold, and it’s not the first time the older OS has proven the more popular choice either. It’s becoming something of a regular occurrence. Adoption of the tiled OS is slow, very slow. Especially compared with the strong pick up Windows 7 enjoyed from the start. And people say that Windows has no competition

I still can't get it to install. I sent one of the hardware companies an email asking them to update their driver, haven't heard anything yet.

Would be interesting to see uptake curves for a few other Windows releases. W7 probably got a boost because people who avoided Vista finally upgraded. At a minimum I'd like to see that upgrade curve; and wouldn't mind seeing XPs and maybe 2ks curves too since both were "normal" new OS releases that didn't either have major release day issues nor follow a version that did.

Microsoft has famously lost -- or ousted -- eight top executives since 2008, including luminaries Ray Ozzie and Jeff Raikes. The change of leadership might have questionable long-term effects, but isn't likely to change much in Redmond for the time being. Here's why. More of what Ballmer hath wrought

Interesting, Windows 7 was released in 2009, and since this "execudus" the next OS to be released was the half-baked Windows 8? Seems the old executives were better then whoever they have now.

This article is from 2011.
Even if you missed the date, this paragraph
Quote: Perhaps it was inevitable that Ozzie would never fully fill Gates' shoes. That's partly because Gates is so unique -- but it's also because Microsoft is Steve Ballmer's company now, and observers say that he wants to run things his way.
should've tipped you off that the article was old.

Fair cop.
I really need to keep reminding myself to check when following Reddit links. Sometimes these things echo.
It would be interesting to see an updated version, as many more execs have been purged since then.

In the past few months, Samsung has come at developers on all fronts. Through conferences, incentives and new SDKs designed for living room device convergence, the South Korean tech giant looks to reduce Android dependence and unify devices by expanding its software presence.
Come towards the white van, Android developers. We have candy!

In almost every software project I've been a part of, the majority of errors I've encountered are caused by unexpected null references. Many are caught at compile or test time, but they always creep though, and few platforms are exempt. They crop up everywhere: web applications, desktop applications, embedded software, game consoles, mobile devices -- almost everywhere there is software, there are null references. And 'X considered harmful' headlines considered irritating

I wasn't sure how Obj-C handled null - but on checking it looks like you have the potential for both null pointer exceptions (when a null pointer is used in C code) and nil reference issues (when a message is sent to a nil object). The latter can at least be handled (I'm not sure how useful the "silently ignore messages sent to nil" option is).
Effectively though, the situation remains that the programmer must remember to check for null/nil everywhere and handle appropriately - which evidently does not happen as often as it should (always).
In Smalltalk, each object can implement a doesNotUnderstand: message, but there is still a nil object (effectively a null) that doesNotUnderstand: any messages. The doesNotUnderstand: message can be replaced on Object itself, which will catch all such messages (unless overridden in a subclass). All of these options seem non-optimal, and really just mask the underlying problem.
At least C++ has reference types that cannot be initialised to null (well they can, but only by such stupidity as:
int& i = *((int*)nullptr);
So its progress, but not much.
If an error object is used, it can be written to respond to all messages by returning self (this) - consequently such errors cannot be masked. Once an error occurs in an expression, the result of the expression is guaranteed to remain an error object. This is some improvement - a bit more like NULL in databases. (Although many databases also fail to implement NULL properly, for example allowing it to be treated as an empty string when used in string concatenation).
Here's looking forward to a day when lessons that should have been learned 30 years ago are finally learned.
On a similar note on lack of progress in systems, here's a polemic from Rob Pike on Systems Software Research[^] (itself written in 2000, showing just how glacial progress is).

That really isn't news.
Tony Hoare (the inventor of the null reference) wrote in 2009: I call it my billion-dollar mistake. It was the invention of the null reference in 1965. At that time, I was designing the first comprehensive type system for references in an object oriented language (ALGOL W). My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn't resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years.

Ironically, when editing the comment above, the wisdom of the words above was illustrated:
