Algebras
I think the place to start would be to understand the idea of an algebra. This is just a generalization of algebraic structures like groups, rings, monoids and so on. Most of the time, these things are introduced in terms of sets, but since we're among friends, I'll talk about Haskell t...
Or rather, I have no idea if it is normal, but two out of three wireless networks which I use do vary a lot. Sometimes having a nice 54Mbit signal, then dropping to 2mbit, 1 mbit, 9 mbit, and back to 54 without me moving. Or without anyone getting in between the WAP and the laptop
I most cases repositioning the WAP and setting a fixed channel helped.
Strongest signal as in: 1) Windows sees multiple access points. One has a stronger signal tan another. 2) Somehow the signal strength changes (e.g you move, or a butterfly flaps its wings). 3) Windows moves to the AP with now has the strongest signal.
That can be a very useful feature. But not if two AP are nearly equally strong and windows ping-pongs between them
If you use the B/G bands (2.4GHz) then there is an object which is very good at blocking the signal. It is about a 2 meter tall bag of water. (aka a human)
When I used to drag a window with my mouse it moves with the mouse, but when I release the mouse the window stopped there. Now, however, it will show the outline of the window when I am dragging it, then I release the window and it stops, but there is an outline as well. Here is a screenshot of w...
Hey folks, I’m trying to help out a user who posted this question on Arqade. I could have sworn I remember seeing a question on SU that I could link them directly to, but I can’t find it now...
So I wanted to start out fresh and never go back into my older saves so I deleted all 400 something saves. Now I've changed my mind so I want to get those deleted saves back. I deleted them from the recycle bin already.
Okay, so if you delete a file by accident, is it better to power off the PC with the shut off option, where Windows writes a bunch of stuff and saves, or just pull the plug and not write, then deal with the little risk the filesystem/something messes up?
if you have a huge hard drive and most of it is very rarely updated with a ton of free space, the chances are decent, but even then, windows writes to its page file pretty rampantly
@MichaelFrank well, with my Windows 8.1 desktop with 32 GB of RAM, it's like, "OMG, I only have 24 GB of free RAM!!!! time to write EVERYTHING to the page file!!!!!!!!!!!!!!!!!!!!!!!!!! I need 33 GB of free RAM on a 32 GB system~!"
I recovered a Windows key from a laptop the other day onto a USB for safe keeping, I then proceeded to put that USB in my desktop and format it to use as a bootable ISO.
But if you have pages in RAM which might serve better as cache in a few minutes and you have free IO space now, then you can write them to the page file AND keep them in memory. Should you need the memory then you can just drop the in-memory copy
I named a folder " ", the symbol for a space.
In Linux you can create folders with just a space. Now that I've switched over to Windows, I can't move the folder that has the folder named " " in it. Nor can I move anything in the folder itself, or rename the folder.

After couple of tests using zombie I came to the conclusion that it's still to early to use it for serious testing. Nevertheless, I came up with working example of form submit (using regular .submit() method).
var Browser = require("zombie");
var assert = require("assert");
browser = new Browse...

> If you call wait with a callback as the last argument, it will be notified once on completion or when the first error occurs. If you call wait without a callback, it returns a promise that you can wait on.
Here's an example of a 'promise' used with browser.visit:
In functional programming, continuation-passing style (CPS) is a style of programming in which control is passed explicitly in the form of a continuation. Gerald Jay Sussman and Guy L. Steele, Jr. coined the phrase in AI Memo 349 (1975), which sets out the first version of the Scheme programming language.
John C. Reynolds gives a detailed account of the numerous discoveries of continuations.
A function written in continuation-passing style takes an extra argument: an explicit "continuation" i.e. a function of one argument. When the CPS function has computed its result value, it "return...
(because they didn't have the balls to make a naturally non-blocking runtime like Haskell or Erlang, but that's another conversation)
@JimmyHoffa because the webpage's DOM contents change dynamically when JavaScript is evaluated within the context of the page, and it has to wait until that operation completes before it tries to start finding elements on the page, but it seems to be plowing ahead without knowing that it isn't done loading yet, and I'm getting an undefined document object
@JimmyHoffa I explicitly ask it to evaluate a specific javascript function available in the client page that gets me to the next step of the authentication
@allquixotic What does that function do? If it changes the DOM it's probably not very well behaved, you should probably execute that javascript yourself rather than scraping it
there is even a function in the API that claims it will repeatedly call your test function in a poll loop and keep trying until it returns true, and I copy and pasted an example from the documentation that uses querySelector to try and find an element, and it never even calls my function
that's not how this is working -- this isn't "make an http request" land; this is "manipulate the DOM" land -- that's the point of using zombie.js... otherwise I might as well just write something in, like, Ruby, where things actually make some semblance of sense
I'm pretty sure this isn't a static URL that I can rely on (there's more stuff where the "..." is): openid.stackexchange.com/affiliate/form?affId=11&bac…Uo7EJ4ph2i2l5YQd8mk9q3vaGvZ8tD1rGsggAy53QP4a49N4iPFzb1d4c%3d
@allquixotic that URL is an OAuth generated hash attachment
I know I dug that same URL out and that's when I realized they're just using OAuth, so all you need to do to generate that URL is use an OAuth library
I wrote an OAuth library at work as well as having used some open source ones in the past hand full of months because we're moving to it, it's boring code and just has to be meticulously constructed but not hard per se
let me see if I can't find the URL that explains it the best...
well, that's progress enough for tonight, I guess... TIL that PhantomJS 2.0-ish preview (Qt 5.2 based) works (1) headlessly, and (2) enough gumption in JSCore to load the core bot functionality without crashing and do !!eval of simple math, but fails on coffeescript, no shims needed... getting close to being able to shut down the X server if I can get that !!export and !!import of JimmyHoffa to work
wonder if it'll be as stable as FF has been though... might be worth to keep the X server (despite some administrative difficulties and higher than needed CPU and RAM usage) since FF is so stable and PJS always used to crash like, every few days
@allquixotic I probably got the btoa vs atob wrong, I always get those mixed up because it's not base64-to-ascii it's binary-to-ascii which is the opposite meaning
also I have no idea how to create a command for the bot because I didn't really look at how the whole bot actually works :D
I think there's a mouse in my ceiling. I wonder if I could shoot it using a stethoscope and a nail gun.. but then there would be a dead mouse in my ceiling.
So recently, I corrupted my explorer.exe while modifying the icons. I had a backup of the original explorer.exe, so I went into elevated command prompt via Ctrl + File > Run new task in Task manager (elevated command prompt). This worked, but for some reason, now when I go to my desktop, I have a...
@ErraticFox Obligatory question, even though it's hard not to do this: you did quit the process, and make sure the security rights were correct before launching it again?
... and when you launched it, did you launch it with your administrative rights - or did you do it with your user's rights?
Well, yes. I ended explorer.exe through the Task manager. I then had to change the owner to Administrators from Trusted Installer because I couldn't rename it to explorer.exe.bak unless that was done.
