I continue unambiguously Dating my electronic posts like my paper letters Sorry for this OT (Out of Topic), but I noticed that the Date-and-Time I had added as usual at the end of my post To raise public awareness of the business of Thu 27 Feb 13:43:00 GMT, has been removed, right inside my post...

discussion

he has a weird habit though

of personally writing down the exact date and time of his posting

Raised 4 children (1 DB analyst, 1 tri-lingual assistant, 1 officer, 1 engineer).

he does seem like the type to make sure his sons become crazyass performers lol

Almo

:D

you assume sons... interesting

chicks can do those things as well :)

MickLH

pfft... yeah @AlexM. dont be so sexist

Alex M.

8:46 PM

don't even get me started :A

I'm actually trying to behave

you know

Almo

:D

Alex M.

I think I should get rid of my global message array and just let each module take care of its own input and output

MickLH

sounds reasonable

Maybe provide some utilities though!

Alex M.

utilities?

MickLH

I mean, like re-packaging the global message queue code

So it's easy to port the modules

Alex M.

8:50 PM

considering I'm just starting, would that be relevant?

I mean, would porting be required if I get rid of the queue now?

MickLH

Yes

Alex M.

not sure what you mean

gief example

MickLH

Let me think about my words for a moment

Alex M.

I thought about using the queue to allow for multiple modules to use the same I/O channel but in practice that happens quite rarely or never

MickLH

If your modules relied on a queue system provided from somewhere else, if you remove that queue system, it might be useful to make a queue library out of it, so your modules don't have to implement the same queue over and over

Alex M.

8:52 PM

I mean, one module will do its own stuff, like downloading some XML from somewhere

another module will start its own UI

@MickLH I think I get it

I don't think it applies; it's really just one module now

I still need some way to do inter-module communication

MickLH

I'd melt that goal together with the queue system, and then make it all happen in the module manager

Alex M.

so the queue can still stay there

yes

MickLH

Lol why is it so awkward to talk about such simple programming concepts

Alex M.

I have no idea lol; what I'm doing here is pretty simple

you make it sound so complicated

MickLH

It's like it gets easier with complexity

Alex M.

8:55 PM

I think

I should put up some use cases

that would be best, there might be some use cases that are not as easy to do as I thought

Lasse

awesome music now playing in my spotify music drop

►

MickLH

Also feel free to tell me off whenever, I just offer API consultation in hopes that I get some back when I need

BlueBug

My Godzz That vocal is overwhelming

Alex M.

like, the news reader downloads some RSS feed, and for each item it checks with the facts module to see if the user likes that kind of stuff, then shows it

Lasse

dat vocal, dem basslines and everything

Alex M.

8:57 PM

so I need some sort of IPC set up between the threads (1 thread per module)

but not all of them require the interaction with other modules

so I need to make it an optional part of each module's loop

Almo

woa! stackoverflow.com/questions/21947452/…

which massive atak song is that

Alex M.

yeah, having each module manage itself is the way to go

there will be one interacting with an android app anyway

can't find a simple recipe for all of them

MickLH

Maybe use a linked list to represent the message queue, and feed IPC messages into the same queue

Then if there's no use for the list, it never gets allocated and the null pointer shows it's empty

or the same idea with two queues, for IO and IPC, idk what your app is

Alex M.

a linked list would give me extra work to do w/ concurrent access

ideally, when a module finds a message for itself in the queue, it gets and deletes it

Lasse

@Almo If you click it you will see it

Alex M.

9:03 PM

so I have to use a semaphore w/ an initial value of 1

essentially a mutex

Almo

but i got my deepchord on

MickLH

@AlexM. I believe you will need something about the same regardless of what route you take

Alex M.

that sort of kills concurrency there

Lasse

Paradise Circus (Breakage's Tight Rope Remix)

Alex M.

@MickLH having something indexed based on module IDs doesn't cause issues though

not sure what the # of modules will ever be but...

MickLH

9:04 PM

But then your list is fixed size

it only makes more concurrency possible unless you were ignoring something before

Alex M.

if (input_messages[my_id] != 0) { get it }

MickLH

that's not thread safe unless you are using compiler extensions

well I'm thinking of C++ actually

Almo

ok, not heard that one

MickLH

not sure if it's the same in C#

Almo

only heard mezzanine and 100th window

Alex M.

9:05 PM

it's plain C

are you sure accessing and modifying things in an array, not at the same location, is not thread safe?

MickLH

ah, then unless you are using a volatile on gcc, or whatever the MSVC version is, it's actually not thread safe

@AlexM. I mean't using the variable for IPC

Alex M.

say, thread 1 changes arr[0], and thread 2 changes arr[1]

what could go wrong?

MickLH

That's probably fine, I mean when thread one is writing the flag, and thread two is reading it

Alex M.

aaah, I get it now

MickLH

You'll probably get away with it forever if you just say fuckit

But sometimes the compiler makes crazy optimizations, where it decides to not ever check the memory and just go into an infinite loop

Alex M.

9:07 PM

I guess nonatomic stuff doesn't get written in one bit

so the reader could only get half of what's there, before the write is done

is this what you mean?

MickLH

yes that too

Alex M.

yeah didn't think of that

MickLH

and a whole plethora of unpredictible cache issues

that change from chip to chip

Alex M.

I'd rather set up something better right now

I'll think about it

thanks for the insight

MickLH

glad it could help! :)

I was afraid I was rambling about useless crap you already thought of

Alex M.

9:11 PM

there was this standard IPC method on UNIX platforms that used some sort of read/write messages by ID by default

it was probably the message queue

Lasse

One more and then I'm gonna start playing something and silence for some time

►

Alex M.

The structure member msgtype is the received message's type as specified by the sending process.

yeah, this should do it

I guess the POSIX message queues already provide what I need

does Windows have this too, last time I checked it had mailslots

why am I even bothering with it anyway, I'll run this on Linux machines

MickLH

lol

Well I've gotta go check up on my engineers and literally make sure they aren't doing heroin

Alex M.

sometimes I think whenever you say stuff like that it's really just metaphors for peeing

or taking a shit

MickLH

hahaha

that's why I said "literally"

-_-

hasherr

9:26 PM

hey guys

MickLH

hi @hasherr

Ironically, we'll end up doing drugs all weekend like usual :D

but not H!

hasherr

H?

Is that a reference to me?

MickLH

Junk

no

it means heroin lol

hasherr

k

Heroin's some bad shit, yo

MickLH

yeahhh.... it's uh... yeah bad, but not as bad as everyone makes it out to be

hasherr

9:27 PM

...

It's fucking heroin dude...

MickLH

which to an engineer is a misleading situation, so he gets this idea that it's not that bad in general

hasherr

Some drugs are bad.

Almo

Aspirin isn't bad

MickLH

anyways, I'm heading out for a while, peace guys!

Almo

Ibuprofen isn't bad

MickLH

9:29 PM

lol

Almo

calcium chloride isn't bad (tums)

MickLH

see you on the other side

Almo

bye mick

hasherr

@Almo I said 'some'

Bye Mick :P

Almo

you said "most"

hasherr

9:31 PM

Wrong word, I edited :P

Alex M.

are "some" and "most" that different in this case?

hasherr

Yes

Alex M.

I mean, suppose the set X of drugs

hasherr

Pretty much all drugs can be good when used in the correct moderation.

Except for krokodil.

Alex M.

some is included in but not equal to X

Almo

9:32 PM

Avelox, while considered a last resort antibiotic, did save my life, apparently

the pneumonia would not repsond to anything else

Alex M.

most is included in but not equal to X, with the property that count(some) < count(most)

Almo

some usually implies like... 1/3 or 1/4

hasherr

I am the son of a pharmacist, so I know a little bit about this.

Alex M.

let Q be equal to count(X) - count(some), and Z to count(x) - count(most)

nah I'm getting nowhere

hasherr

@AlexM. You remind me of the AP Computer Science students I know.

Alex M.

9:33 PM

what I was trying to say is

both "some" and "most" leave drugs out

that don't apply to the rule

it's just that one of them leaves out more drugs than the other

Almo

most means like 3/4 or more

hasherr

I'd say 4/5 personally

Alex M.

I don't quantify "most"

most is unspecified by nature

Almo

still, most means "significantly more than 1/2"

hasherr

^

Almo

9:34 PM

some means "significantly less than 1/2"

Alex M.

for a set X { 1, 2 }

would you say that most numbers in there are odd?

most = some here

Almo

for a set { Alex, pedantic weirdos } all elements are indistinguishable from each other

hasherr

xD

Almo

I would say "half the numbers are odd"

Alex M.

also for a set X { 1, 2, 4, 6 }

Almo

9:35 PM

i would not use some or most in that case

Alex M.

"some X are even" still holds true

hasherr

Why are we discussing this?

Almo

I would feel misled

Alex M.

because we're in a chatroom dedicated to science

Almo

if you said some when in fact it was most

Alex M.

9:35 PM

do you wish to see more porn pics?

hasherr

@Lasse Hello, Fin.

Alex M.

@Almo that may be true

but the statement is still true

hasherr

@AlexM. Game dev and boobs all in one place? This is the best chat ever.

Alex M.

some of the numbers there are even :D

Almo

you've got the connotation all wrong

language isn't all about super-precision, unless you're a lawyer

it's about communicating something

Alex M.

9:36 PM

I just don't think some and most are mutually exclusive

Almo

and "some" does not communicate "3/4"

Alex M.

I think you could say most -> some

but of course some !-> most

Almo

strictly speaking, some could mean any number, including all.

Alex M.

yup

Almo

but that feels like a pedanic cheat, if it comes up in conversation

because it's not how the word is used in ordinary speech

Alex M.

9:38 PM

but this is a discussion about the meaning of the words, not the daily usage of them

hasherr

I think I'll work on Webdev today

Alex M.

I mean nobody goes to their mum to say

Almo

and if you got in that fight in a conversation with someone, they would think you were being one of those weird engineers who doesn't understand the difference between science and every-day communication

hasherr

What other text editors are there besides Sublime and Notepad++?

Almo

ConTEXT

Alex M.

9:38 PM

"would you say most of the cereals in this box are wedge shaped, or some of the cereals in this box are wedge shaped?"

Almo

I use that one

Ultra Edit is popular (i assume you mean windows)

then there's vi and EMACS.

Alex M.

@hasherr gVim

Almo

but i doubt you meant stuff like that

hasherr

Vim?

or gVim?

Alex M.

Like vi, Vim's interface is not based on menus or icons but on commands given in a text user interface; its GUI mode, gVim, adds menus and toolbars for commonly used commands but the full functionality is still expressed through its command line mode.

you want this on Windows

hasherr

9:40 PM

Yeah?

Alex M.

I recommend printing a cheatsheet with all of the useful commands

and eventually reading a book about using it

Almo

if you get fast with vim, you'll love it

I still use it for bash scripting and stuff

Alex M.

right now I use it for everything

hasherr

@Almo What do you use Bash for?

Almo

any time I have to move or rename files and it involves a ton of files, I get out bash

also good to have grep

and other assorted unix shit at times

hasherr

9:41 PM

Okay, so wait, is it called gVim or Vim?

Almo

Cygwin gets installed day one on any windows PC i'll have to use

hasherr

I can't tell if Alex mistyped that or if gVim is a real thing.

Almo

try google man

it's faster than asking and waiting

Alex M.

hasherr has a big issue with googling

I noticed that

Almo

yeah

Alex M.

9:42 PM

nothing's changed in the past year

hasherr

I wouldn't say that's true.

Alex M.

@hasherr another nice thing about Vim is that you can port your settings and plugins easily

they're all in Vim's folder, so just copy/paste them

hasherr

I Google more things than I ask here by a long shot.

Alex M.

except for the more... complicated plugins

like You Complete Me

which requires a shitload of crap

Almo

but you fail to google some really basic shit

Alex M.

9:45 PM

I never tried it just because of that

I still don't get what it needs all that stuff for; it's basically a fuzzy pattern matching autocomplete engine

Almo

you never know

Alex M.

my current autocomplete plugin only uses vimscript

Almo

once you include one lib

hasherr

@Almo I sometimes feel like I have to ask questions under a certain context.

Almo

it includes some libs

and pretty soon you've included the whole world

Alex M.

9:45 PM

my goto-anything plugin only uses vimscript too, and does fuzzy pattern matching

Almo

but you could just google "gvim" and find out if it were real or a typo

Alex M.

@Almo this one needs python interpreters and C compilers

Almo

and you don't need to ping me if I'm here

woa

ouch alex

Alex M.

and it's so hard to set up on Windows (as on most platforms) that one guy made a repo on github specifically to help newbs install it

hasherr

@AlexM. That's common.

I find stupid shit like that all the time.

Alex M.

9:47 PM

perhaps one day I'll give it a try, when I'll be bored enough

Almo

./configure scripts always amaze me

holy shit they check a lot of arcane shit

like wow man

M Davies

I've tried installing git on my machine and it does not work. And I have tried everything to get it to work.

hasherr

Eh, I don't feel like setting up something like this right now.

@MDavies I'd start with following the instructions.

M Davies

I did follow the instructions, lol.

Oliver Schöning

Omg.. words... I can not explain what I want to say properly

hasherr

9:48 PM

Well what's the problem?

Alex M.

@MDavies "does not work" sounds like my grandma explaining what her computer does when misbehaving

M Davies

After following the instructions it still doesn't work.

Alex M.

"I have tried everything to get it to work" then you can't get it to work

why waste our time asking, then?

also, your time

M Davies

I'm not asking.

I'm just expressing what happened to me. I gave up long ago trying to get it to work. XD

Alex M.

aight then, there's no problem

carry on with what you were going to do anyway :D

Oliver Schöning

9:50 PM

I have a 2D game. Where you control a shark Up and Down. But the world is in 3D. Meaning that some objects will be placed closer or further away. Collision still sees it as 2d and the shark would move left and right on its own

Almo

just use perforce

hasherr

@AlexM. Do you really think that?

Almo

it's free now for 20 or less workspaces

Alex M.

@hasherr don't get all dramatic on me hasherr

hasherr

I'm not, just trying to understand.

Almo

9:51 PM

pet peeve... files with } as the last line, not a blank line (or 2 or 3)

M Davies

Why is that a pet peeve?

Almo

It just annoys me when I'm on the last line and I try a usual keyboard short cut to do something, and it fails because there's no blank line for the cursor to go to

Oliver Schöning

something small that is annoying you. Like being anoyed when people chew with open mouth @MDavies

Alex M.

depends on where you inspect the files

suppose you're running on an UNIX terminal

Almo

people who chew with an open mouth DO annoy me

M Davies

9:53 PM

I know what a pet peeve is Oliver. I was asking why it peeved him. :P

Almo

this is why I'm so damned good at gameplay programming and gameflow design

I know when something is annoying, and I know how to fix it. :)

Oliver Schöning

Ahh :p

Alex M.

A: Why should files end with a newline?

There's at least one hard advantage to this guideline when working on a terminal emulator: when moreing the file on the command line (more displays the file) or catting multiple files (cat = concatenate input files), it results in a correct display. Otherwise the result is something like this: k...

this answer explains it better

so newline-ing EOFs is NOT exactly a preference

in some cases as those above it CAN cause issues

M Davies

I'm still struggling to understand the concept of vertices and normals in OpenGL ES 2.0

hasherr

@MDavies No use getting frustrated in it

Go build something

Grey

10:06 PM

such change

very avatar

hasherr

@Grey Dat afro

user4704

@MDavies What about them?

Oliver Schöning

@hasherr Thank you hasher.. I tried to draw my problem in paint, and I think I found a solution

M Davies

@Josh Petrie Just don't understand how the device context handles them as seperate buffers.

hasherr

@OliverSchöning Why thanking me?

Oliver Schöning

10:08 PM

I think you asked me what the problem was, so I started drawing it when words kept failing

or mb i misread. who cares. progress

hasherr

Indeed. Commence work.

I'm going to go practice Googling.

M Davies

@JoshPetrie I treat them as separate buffers but does that mean that the indices buffer looks at the exact same indicies for both buffers? So if I specify 0 1 3 in the indices buffer does it look at 0 1 and 3 in the both the vertices and normal buffers?

Alex M.

@Grey why did you switch your main account?

Alex M.

10:52 PM

chrome decided to take up another GB of memory on SE

fuck this fuck

BlueBug

yeah... running Chrome is equivalent to three Hearthstone, or two FPS games to me. only SE? SE memory leak? really? I guess experts do make a mistake o_o

Alex M.

no, it's a memory leak

and it only happens on SE

hasherr

@BlueBug Why do you edit your posts instead of adding new messages?

@AlexM. Uhh... Is this true? lol globalpost.com/dispatch/europe/110105/…

BlueBug

I tried to respond to you by editing my old chat but alas, it's too old for new edition. I like keeping less nutritious chat messages of me minimal since I already do humongous amount of rambling.

Alex M.

@hasherr I remember something like that

I think it was just one of those "whoa" news meant to distract the population from more important things
