stop using containers guys. embed your container in your app, not the other way around. java doesn't need any external help to listen for http

the real answer to classloader/container hell: embed jetty in your app, run every component in its own jvm and its own unix service.

i used to poke fun at devs who did this until i tried it for myself in a hobby app. never, ever going back.

i had issues with storm because storm workers use the same classloader for everything. servlet classloading works pretty good imo for single-tenant

this happened to me, too. storm wants to keep everything in the same jvm, surprise surprise that's a multi-tenant setup that's gonna need complex classloaders

storm re-invents a lot of java wheels because it was written by a p-lang weenie. c.f. it jumps through insane hoops to avoid xml at any cost w/ all those python startup scripts

ugh goddammit

so

right now we're doing this

code:

$.getJson(url, callback)

which according to the jquery docs is equivalent to

code:

$.ajax({
    dataType: "json",
    url: url,
    success: callback
})

but the top one calls the callback while the bottom one does not. and i need to use the bottom so i can throw a timeout in there. what gives

# ? Jun 5, 2014 18:57

Careful Drums: Oct 30, 2007; by FactsAreUseless

something else is going wrong because i've used callbacks like that bottom snippet. stupid question: 'callback' is a function right?

e: is it possible you're getting a 500 and the 'error' callback is happening instead?

yes it's a function. here it is in angular being used in our app right now:

code:

	$scope.init = function () {
		$.ajax({
			url: Globals.baseUrl + 'Rest/tileD/PendingData?forDate=' + Date.today().toString('yyyy-MM-dd'),
			method: 'get',
			dataType: 'json',
			success: function (result) {
				if (!result.isEmpty) {
					$scope.hours = result.Data[0][2];
					$scope.tasks = result.Data[0][1];
				}
				$scope.$apply();
			},
			error: function () {
				$scope.$apply();
			}
		});
	};

you're missing a semicolon at the end of that, otherwise its fine.

JavaScript code:

$.ajax({
	cache:false,
	type: "POST",
	url: secreturl,
	dataType: 'json',
	success: callback
		
});

litterrally using this right now and it works fine. its even cors!

here is how to enable cors in webapi
in WebApiConfig.cs

C# code:

config.EnableCors();

add enable cors attribute either per controller or per method

C# code:

[EnableCors("*", "*", "*")]

lol. so you are using appdomains only because you don't have classloaders.

(as with so many .net vs java differences, this seems like a case where .net makes different tradeoffs but isn't actually better or worse)

this is basically why they dont have dlclose and have the marshaling requirements but it's just a pita.

no i mean like lets say i do some some poo poo like

$(selector).removeClass(class0).addClass(class1)

can i make any guarantees on the page never showing those elements w/out class1 or what

what i've heard is browsers will try to store up all the dom changes and do one redraw when your code returns, but i don't know if there's any guarantee

it has to reflow the page if you read layout information after you've changed the dom though, so you can trigger worst-case behavior by alternating reading and writing.

i had to update our deploy process yesterday because we're now dependent on a java thing and: no java runtime on the far end, so i just shoved a hundred megabytes of /usr/lib/java/default-java or w/ever in there and updated a couple environment variables and : it worked

if you didn't setup the server yourself, 99.999% of the time the java install will be hosed because its probably from a package manager, so copying the java bins is standard practice for deployment on Linux.

for windows theres really only the sun vm so its not a problem, but I still copy the binaries anyways cause theres no need for it to be integrated into the browser or os or anything.

ibm ships their own jvm with any of their products that use java (ex: notes/sametime/domino) so you don't need to install java separately.

copying the jvm with ur poo poo is pretty normal.

# ? Jun 6, 2014 14:53

Shaggar: Apr 26, 2006

like you don't even need environmental variables if your thing is going to be the only thing using the jvm you copied (in fact its probably a good idea not to in case other people want to use other vms).

copy-quotin into this thread cause there are a fair few UK devs itt who i respect n id like to know their opinion

coffeetable posted:

UK advice needed: I've been unemployed for nine months while learning software development, and a few weeks back I finally decided to put 10 resumes out there to see what the reaction was. Got 4 interviews off the back of it from all over the country, and that's panned out to two poor offers and one seemingly-decent one: �35k in the north of England for a small biotech company. They want me to join a two-man team who're developing a research-council backed project, with a look to leading it by the end of the year.

The pros for taking the job is that it would probably afford me much more responsibility than I'd find in an entry level position, that it'll make use of my maths background and that there's a small but non-zero chance of getting some publications off the back of it. The cons are that it's not London, it's nowhere near a good London salary, and that they probably wouldn't be offering me the position unless they were starved of decent developers.

The alternative is to back off for a few months and turn out another small project, and then go about applying for jobs properly, sending off hundreds of CVs every which way. Right now I'm leaning towards taking the job and staying with it for a year or so just to get some experience on my CV, then I can re-evaluate and consider a move to London. Does this seem sensible?
