Oh. So maybe you won't have such a great celebratory party when it doesn't happen.

I definetely prefer if it doesn't happen - furniture costs a lot and it's all fairly new. Plus my costly new computer - which alone costs as much as my whole kitchen furniture + appliances.

I feel your pain. I've just recovered from a nasty little bug and it's not that long ago that I was having to do some work with VB3 (I kid you not - but it was Ok because we were upgrading the software to .... VB6  )

Sounds like snowboarding is out 
Ah, I see you have the machine that goes ping. This is my favorite. You see we lease it back from the company we sold it to and that way it comes under the monthly current budget and not the capital account.

So they've been promising 30-45 cm snow for today
We're expecting 6-12 inches but ..., Since yesterday, I've been jokingly telling my friend that a fake news.

I just heard our local weatherman claim this deserved to be called the snowstorm of the century.
Just like the 3 other ones he described in the same way last winter.

That's why I've taken to checking out the NWS for my weather. Particularly for extreme weather.
No emotion. No need for ratings. No opinions - just probabilities.*
Then, too - why not hype it? Everyone seems to go and buy out the supermarkets whenever the sky determines it's time to phart. There has never been a food shortage that I can remember - except for Sandy - and that wasn't a real shortage since you couldn't stay in your home, anyway (and the food they bought was ruined).
Must be a need for millennials: they don't have good movies, music, or, with their face glued to their phone, a life. I guess they need something to be proud of.

Wall (bathroom) should be much more prominent, as should Apache Request log.
Not because they're more used, but because they're better used.

Instead of just complaining about it, I set out to fix it. Although maybe "fix" is a big word for what I'm doing since I'm not building it into the language, just adding it on as a class library. As a result it does not mix with normal code well.
Here is an example of what it would look like:
SIMDcode s = new SIMDcode(_ =>
{
var ptr = _.arg(0);
var size = _.arg(1);
var constants = _.arg(2);
var w = _._mm_loadu_si128(constants, 0);
var shufmask = _._mm_loadu_si128(constants, 16);
var alpha = _._mm_loadu_si128(constants, 32);
_.repeat(size, 4);
{
var p = _._mm_load_si128(ptr, 0);
p = _._mm_maddubs_epi16(p, w);
p = _._mm_add_epi32(p, _._mm_srli_si128(p, 2));
p = _._mm_srli_epi32(p, 6);
p = _._mm_shuffle_epi8(p, shufmask);
p = _._mm_or_si128(p, alpha);
_._mm_store_si128(ptr, 0, p);
_.add_r_i(ptr, 16);
}
_.endrepeat();
});
The "meat" looks just like "intrinsics" like you're used to (or not, if you've never worked with them), but in this case they're not proper intrinsic functions. When executed they build up some internal representation of the code, which is then compiled and written to unmanaged memory. That is also why it needs the "weird stuff" such as `arg` and `repeat` and `add_r_i` - normally normal code fills those rolls but here normal C# code will just execute once, it does not itself end up in the native code.
The native code generated by the example above is
push rbp
mov rbp,rsp
vmovdqu xmm0,XMMWORD PTR [r8]
vmovdqu xmm1,XMMWORD PTR [r8+0x10]
vmovdqu xmm2,XMMWORD PTR [r8+0x20]
15: vmovdqa xmm3,XMMWORD PTR [rcx]
vpmaddubsw xmm3,xmm3,xmm0
vpsrldq xmm4,xmm3,0x2
vpaddd xmm3,xmm3,xmm4
vpsrld xmm3,xmm3,0x6
vpshufb xmm3,xmm3,xmm1
vpor xmm3,xmm3,xmm2
vmovdqa XMMWORD PTR [rcx],xmm3
add rcx,0x10
sub rdx,0x4
jnz 0x15
leave
ret
To actually invoke the code you define a delegate and ask for a function pointer of that type:
delegate void ToGrayDelegate(IntPtr pixels, int length, byte[] constants);
...
var f = s.GetDelegate<ToGrayDelegate>(0);
Just invoke that as normal. (this runs in 1 cycle per pixel on Haswell, the best I could do in pure C# was 6 cycles per pixel)
This is just a preview, and maybe that's all it will ever be. A bunch of things work, a lot of things do not work yet, because I just threw this whole together in a day.
Anyway I'm not sure how useful this actually is. On the one hand, you wouldn't need a separate C++ project that has to be kept in sync with the main project (but that's not even a real problem). On the other hand, it's more annoying to write code like in the example than to just write C++ with intrinsics. But this way the code can be tuned with run-time parameters (but is that even useful? and you can't do it too often since compiling more code obviously costs time). Theoretically this can easily support x86 and x64 simultaneously (that's a bit of a hassle with native dlls), but choosing one of them at compile time isn't really a problem anyway.
Compared to System.Numerics.Vectors I'd say this is a lot better - it actually allows you to get stuff done, there are all the usual things that you need such as shuffles and shifts and oddball instructions like vpmaddubsw. But compared to a C++ dll it doesn't seem all that useful.
So what do you think. Useful? Interesting? Total waste of time?

Nevermind what anyone else says, this looks fascinating. I would love to see an article or three about this.

An interesting idea. As Pete says, I'd like to see a proper article written about this.

I second the opinion that an article on this would definetely be interesting, I am a user of SIMD and intrinsics and while I plan to use C# (if and when we will be able to spend the due time necessary to rewrite 60kloc in VB6 unto muche less C#) only for the GUI and leave the meat of elaborations and hardware and I/O processing in C++ I would definetely bookmark such a technique as it could prove useful in a number of situations.

If you are not already doing so.
Thought I would share this real world experience with some of the newer developers here.
Do you think you deserve a promotion or a raise in pay? Ask for it.
You can't expect anyone to advocate for you other than...you. I try to take care of my team, and reward those who are on the radar, but sometimes that falls through the cracks and I miss things.
I recently had a team member who felt they were being overlooked on promo/raise. That team member advocated for himself. They brought their concerns to me, we discussed, and now they are scheduled for promo and raise.
It doesn't hurt to ask. If you work at a company where asking can have negative consequences, then you are working at the wrong company and you need to move on.

Exactly.
However, even if I say no, or upper management says no, that person is now on our radar, and the next time could be yes.
