Hello,
I was curious if anyone has had experience using the MSIX packaging tool. Will this be a true successor to MSI Installs?
|

Sorry, but ms told me that it "provides a modern packaging experience", so I ran a mile.

I've never been convinced MSIX was necessary.
The "X" in MSIX seems out of place to me. It should be used to cross out the whole thing.

I have just had a heated argument cage fight lively discussion with some of my team members about ReSharper's suggestion of refactoring code to replace nested ifs with a series of multiple early return statements. This caused horribly messy code that ReSharper actually described in it's help as "more readable"!
Using a version of their example code (which is a lot simpler than the actual code in question):
void SomeFunction(SomeThing s)
{
if (s != null)
{
if (s.Thing != null)
{
.
.
.
}
}
}becomes:
void SomeFunction(SomeThing s)
{
if (s == null) return
if (s.Thing == null) return;
.
.
.
}This makes a complete hash of the natural flow of the code and introduces an execution statement (return) on the same line as the "if" which is bad coding practice, and then does it again, and then drops though to do some actual processing.
If I was to refactor the code it would do this:
void SomeFunction(SomeThing s)
{
if (s != null && s.Thing != null)
{
.
.
.
}
}or possibly:
void SomeFunction(SomeThing s)
{
if (s?.Thing != null)
{
.
.
.
}
}Which is a lot cleaner!
...and this isn't even considering a method that returns a value of some sort.
Opinions?

I agree.
I will use multiple returns when doing otherwise would be less readable or less efficient, but otherwise I prefer one return.
And I don't listen to anyone who says that a throw or a yield is the same as a return.

I actually sometimes throw exceptions instead of just return and yes I prefer strongly the early returns. It's more modular than the nested hell of mess. Especially when multiple people add crap within a particular branch of ifs.
I looked at the source code of DOOM. John Carmack uses early returns. That should settle it.

That kind of processor cycle counting on a 386 or 486 is outdated, while the algorithmic optimizations remain as current as ever, especially if you are able to delegate them to the graphics processor. Early returns as a way to waste no processor cycle too much in a function is only rarely important anymore.

That is true, but it has other benefits too. Generally as a principle I prefer within a piece of code, if the task is done within a branch it should exit immediately. Later these blocks can be moved out to separate methods or classes. I work in a team where a couple of the members like to add thousands of lines of code in a single method and management tends to let us do whatever we want. So on one hand I really like being left to do what I want in terms of programming style, on the other hand they don't let me lecture others on how to code
Usually I start a project, write the skeleton and after the first version they assign others to add features, which lead to those 1000 lines functions.Early returns help me with that. I just take that additional code and put it in a separate method or class

Such long functions can be a pain, no matter what. Early returns definitely are better to follow than deeply nested code with some code blocks being dozens or even hundreds of lines long.

Unless you're an embedded developer trying to squeak out the quickest code on an underpowered processor. I was always getting projects with weenie processors and grandiose firmware requirements. It seems that the hardware engineer had a rather limited grasp on firmware development and how much space/speed would be required for the project. They eventually figured out that I should be involved in the processor and memory requirements selection.

I sure know that. My first computer had a hex keyboard and actually was very much like today's microcontrollers. And I still have it and use it, just to stay sharp.

I kind of wish I'd kept my first computer. It was a z80 S100 bus system where I wire wrapped all the boards except for the display card (16 lines by 64 character with a rf modulator to display on a TV). I had a 2kb monitor program (Zapple) that gave you the standard peek/poke memory, dump memory, input/output to I/O, run from an address and set break points. I use to knows most of the z80 instruction set by the numbers. Good times.

Great! The good old times never ended for me, partially because I would see it as a great loss if that old computer ever died, partially because such old tech is the is the only option to tinker around with as a hobby without getting poor. I'm certain you know what kind of equipment and knowledge is needed when you want to play around with the most modern stuff.
It's more interesting to overcome the limitations of the old stuff anyway. Modern chipsets do that for you, so where is the point in puzzling them together as intended? Why don't you grab a Z80 on ebay and build a new old computer to bring back the old times?

There's actually some modern stuff that's inexpensive. Look at some of TI's Launchpads. They're on the order of $25 and the IDE they provide (Code Composer Studio) is free. It's based on Eclipse so it's pretty powerful. The last project I was working on before I retired (woohoo!!) was based off of one of their Launchpads. I was able to get a lot of the code working before we got our own hardware up and running.

Yeah, there is that. So far, I've only found 1 version of Code Composer Studio (CCS) that worked reliably for me (version 7.4), all the later versions I tried would work for a bit and then would stop letting me reliably debug my code through the jtag device. I'd have to close CCS and restart it to be able to reconnect to our hardware. Sometimes had to unplug the (USB based) jtag device and plug it back in to get it to start working again.
I only used CCS for compiling and debugging, the rest of the time I used my own favorite editor to write the code.

That is the best advice I have seen from re-sharper and I've seen it show some bad alternatives
one was and only know it was re-sharper as the Dev stated it was what re-sharper advised him to use
public bool someMethod(int valueA, bool Valueb, bool ValueC)
{
var output = DoSomethingElse(ValueA, ValueB) ? RunAnotherMethod(ValueA, output.SOmething) :
DoAnotherMethod(ValueB, ValueC) ? RunAthoerMethod(ValueB, output.SomethingElse) :
DoYetAnotherMethod(ValueA, ValueC) RunAnotherMethod(DoYetAnotherMethod(ValueA, ValueC), output.AgainSomethingElse);
}
This horrid IF ELSE statement contains 16 if's
Footnote: I don't like using Resharper

Layout can help a lot:
public bool someMethod(int valueA, bool Valueb, bool ValueC)
{
var output = DoSomethingElse(ValueA, ValueB)
? RunAnotherMethod(ValueA, output.SOmething)
: DoAnotherMethod(ValueB, ValueC)
? RunAthoerMethod(ValueB, output.SomethingElse)
: DoYetAnotherMethod(ValueA, ValueC)
...etc.
}
