coffeetable: Feb 5, 2006; TELL ME AGAIN HOW GREAT BRITAIN WOULD BE IF IT WAS RULED BY THE MERCILESS JACKBOOT OF PRINCE CHARLES

lol nvm figured it out

new Thread(() => { FlingThePoo(butts, yourMom); viewModel.status = "Done"; }).Start();

boom boom

use

new Task(() => { FlingThePoo(butts, yourMom); viewModel.status = "Done"; }).Start();

or (preferentially)

Task.Factory.StartNew(() => { FlingThePoo(butts, yourMom); viewModel.status = "Done"; })

tasks draw from a thread pool so a) you can amortize the cost of instantiating a thread and b) you won't suffer thread starvation if you start spawning them left right and center

also whenever you modify a thing asynchronously be very careful. if the modification involves a single write that's the size of a native pointer or smaller (like setting viewModel.status to point to a different string), you're safe. if you want to do more writes or larger writes, it's time to do some reading on concurrency.

do the reading anyway. unless the CLR provides stronger ordering guarantees than the underlying hardware, writes and reads may not be visible to each other the way you expect.

could have sworn id read somewhere that .NET had just that kind of stronger memory model, but googling around it looks like i imagined it

as long as the writes occur in order inside the task they should be fine, right?

or better yet don't design a viewmodel that requires things to be updated in a certain order.

in java (which i know more about wrt this poo poo) the guarantee is "within-thread as-if-serial" ie reordering optimizations might well be performed, but only those optimizations that you can't detect from within a single thread. other threads though may well see things happen in a different order from how they're presented in the code

i could've sworn the CLR offers stronger guarantees than that but i can't find where i read it. the closest is a SO post that says the CLR doesn't do write reording on most architectures, but it's not written into the spec

# ? Aug 21, 2014 17:18

rjmccall: Sep 7, 2007; no worries friend; Fun Shoe

if the CLR made that guarantee then it would have to use green threads on any architecture except x86, because otherwise every heap load/store would have to do a read/write barrier respectively

ARM makes a really neat memory ordering guarantee about address dependence that enables a lot of lock-free algorithms to avoid barriers on the read side, but it is not at all sufficient to emulate x86-style guarantees about store reordering

hey now that's not always true. my team just finished writing a production version of a prototype I whipped up a few years ago

of course it took a couple of years of the prototype being slow and inadequate and impossible to fix for management to admit something needed to be done, but it happened!

gimme a jdbc wrapper that
1) makes querying simple (i should just give it some SQL and it should just do the thing and give me result without billion lines of boilerplate).
i dont want automagically created queries, and i don't want to create special classes or whatever for the sake of querying.
2) is updated this year (unlike this https://github.com/jpersson/prequel/)

i know i can use straight jdbc but i want someone else to have already written the irrelevant crap i dont want to write

thats why you disable inputs that can impact the parts of the viewmodel your long running task is working on.

you might as well use straight jdbc cause its just as stupid as writing a pointless "wrapper" around it.

this is where reactiveui really shines

In GitHub for Windows, the Sync Command is an invocation of the Pull Command followed by the Push Command - how can I create a Command whose CanExecute turns off until the Pull then the Push completes?

code:

var canSync = Observable.CombineLatest(  
    Push.CanExecuteObservable, Pull.CanExecuteObservable,
    (pl,pu) => pl && pu);

Sync = ReactiveCommand.CreateAsyncTask(canSync, async _ => {  
    await Pull.ExecuteAsync();
    await Push.ExecuteAsync();

idk. my best guess is that it uses info from a live DB connection to produce more strongly typed things rather than building up/compiling database info/queries at runtime. still don't know where in the documentation it talks about this though.

hackbunny: Jul 22, 2007; I haven't been on SA for years but the person who gave me my previous av as a joke felt guilty for doing so and decided to get me a non-shitty av

I'm going to be immortalized as a plush rabbit:

quote:

Those of you that were with the project when KJK was around might recall him and I creating something of an injoke wherein our secondary aliases, Hackbunny and ZWabbit, were in fact AIs. I expanded the idea a bit further in creating a kind of alternative story for the project wherein ReactOS was trying to create an AI, not an operating system. A few of you have seen various drafts of that story, but I never really finished writing them and let it go by the wayside after KJK left. The Hackbunny plush (it's going into production by the way, the person I've contracted has received initial down payment and will be sending me a picture of the prototype before doing the remaining ones) was something of a throwback to those stories, except that I'm pretty sure the majority of the present developers either don't know about those stories or have long forgotten them, nevermind the fact that the community at large never really picked up on the injoke. To introduce them, and potentially set them up as an "official" mascot fallback to beat off further attempts by the community to impose one on us, I thought we probably need to reintroduce the bunnies and their backstory in some way, shape, or form.

To this end, I've put together a short story, ~4600 words and counting at this point, that sets the tone for the alternate project's universe. It revolves around how "we" discovered the hackbunnies were self-aware AIs, along with the project's adoption of a plan they put together to ensure their long term survival. The draft is still very rough, I'm likely to need to add further exposition to make clear the fact that most of this is happening in a virtual reality environment, and maybe add some more padding in between the dialogue, but I'd like to at least get a yay or nay on my proposed intro to the bunnies and my characterization of the developers.

sorry for invading the thread but wtf

PS: the plushies are terribad:

quote:

Here's the prototype that the others will be based off of. The nose will see some adjustment but beyond that this will be what the rest look like.
