what it does of course is allows you to allocate blocks of memory in bytes of your choosing in the form of an array, and then you can print the address ranges and check performance in task manager to see how much memory it uses while you perform various things

fickle aurora Sep 13, 2020, 7:26 PM

#

I had to fix the code, it wasn't allocating properly so I modified it here https://pastebin.com/NPQXXv7x

Pastebin

// Test4.c#include #include #include #inc - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

#

it uses about 340-370k at the start, but you can see if I allocate 100 megabytes what happens in a minute

📎 unknown.png

#

interestingly, windows thinks that 100MB is 98,000KB, the reason for this is that there are 1024 bytes in 1 MB, so I am only really allocating 100000000 / 1024 = 97,656kb

📎 unknown.png

#

and then of course allocating another 1GB of memory on top of the 100MB of course shows a.exe using 1,074,000 KB

📎 unknown.png

fickle aurora Sep 13, 2020, 8:38 PM

#

just to note, this is a 32-bit application so Windows has placed a limit of 2GB of addressable memory address space so it will crash if you try to allocate too much

coral sundial Sep 13, 2020, 9:41 PM

#

sounds like you have a bug to fix

fickle aurora Sep 13, 2020, 11:15 PM

#

the problem is MinGW for windows, while it says it's 64 bit it only compiles for 32 bit and I don't feel like custom compiling GCC on windows

coral sundial Sep 14, 2020, 8:22 AM

If(user input > maxmemory) userinput = maxmemory

fickle aurora Sep 14, 2020, 3:51 PM

#

negative value input into Test4.c would basically change to a positive, except that it wouldn't be the same number since it would be considered to be a binary complement with a sign flag attached to it, and the size_t variable of malloc() would try to force it into a positive number by changing the sign flag, but that would result in a completely different number because it would be a complementary number in binary

#

yes that is complement not compliment, as in, for example the complement of 010 is 101

#

so let's say you entered -1000, that would be 1111101000 in binary.. the complement of that is 0000010111 which is 23, so you would only allocate 23 bytes of memory by asking for -1000 bytes

#

https://en.wikipedia.org/wiki/Negative_flag

Negative flag

In a computer processor the negative flag or sign flag is a single bit in a system status (flag) register used to indicate whether the result of the last mathematical operation produced a value in which the most significant bit (the left most bit) was set. In a two's complemen...

#

wikipedia calls it the negative flag, but everyone else that I know and read about in every single textbook I have ever read calls it the sign flag, even programming languages call it the sign flag.. so yeah this is wikipedia's new made up word, not sure why they want to change the terminology, but at least they did acknowledge that their "negative flag" is also referred to as a "sign flag" ... why change the terminology when you don't have to...

neat fossil Sep 15, 2020, 1:19 PM

#

Nice! icanari. But because you had to exaggerate the contrast (like I had mentioned, if you change the heightmap, you're effectively changing the terrain) it now looks like a river valley between two cliff faces. Instead of rolling hills and farmland.

This is what I was talking about.

ooh ty

lunar cobalt Sep 15, 2020, 7:36 PM

#

I mean, I don't think it really changes it too much. I changed it so there is a visible difference between the layers, but for a topographical map you just have to find the height difference between the different layers, and I'm guessing it's around 2m per line. The point of it isn't to act as a heightmap in another game, in which case saturating it would change the terrain, but for a topographical map it just makes the higher areas actually visible to the eye easier.

vague otter Sep 15, 2020, 7:39 PM

Why not just have the height lines, like on every map ever?

long raft Sep 15, 2020, 7:41 PM

maybe deadlands is just a big river valley between two cliff faces

languid harness Sep 15, 2020, 7:47 PM

The issue tho is that the rocks are not included, so they give only half the image as some important 'hills' are missing on the map

@long raft i thought this is what it proved, live the earth being flat

lunar cobalt Sep 15, 2020, 8:51 PM

@vague otter because of how I grabbed it and I was being lazy

#

Just as a thing: I saturated it after separating the layers so the lines are the same as the height thy should be in-game, just more visible.

why not use GIF if you are worried about data usage, it will be much lower quality but also a tiny fraction of the file size

fickle aurora Sep 22, 2020, 12:05 AM

#

you might be able to write a script or something to make use of pngcrush to reduce the file sizes, that should help reduce bandwidth usage overall

long raft Sep 22, 2020, 12:06 AM

#

you will sacrifice quality and you wont achieve webp size

fickle aurora Sep 22, 2020, 12:27 AM

#

might be able to overlay an image over top of a static map, where the overlaying image is mostly transparent with only the dynamically changing data and the map underneath would be static/cached on each computer

#

that could be done by taking a static clean map and using something like diff to compare that to a current map to find all the dynamic data

#

so then you are only transferring the dynamically changing data to the client

There's plenty of websites that will provide a unique visitor count. depending on how your website is coded you would do it by IP.

#

Which essentially is connections. Depending on how much control you have over your web service, which seems like you have a few

long raft Sep 22, 2020, 8:00 PM

#

doing it by IP undercounts unique viewers, doing it by connection count overcounts it; a session counter would be the closest thing, but still not perfect because a session isnt shared between browsers on the same computer or private browsing tabs - and sessions include overhead

barren quarry Sep 22, 2020, 8:01 PM

#

Just count socket clients

long raft Sep 22, 2020, 8:02 PM

#

so if i open 2 tabs im being counted twice

#

could use fingerprint.js to get a unique machine id, and count those

#

or ip + computer name combination

#

unlikely to have the same computer name as another machine on your local network

barren quarry Sep 22, 2020, 8:03 PM

I'm not sure javascript has access to the machine name

long raft Sep 22, 2020, 8:04 PM

perhaps something useful in the user agent then

barren quarry Sep 22, 2020, 8:04 PM

I probably just said something retarded

#

Either way

#

This task is not worthy of overengineering

long raft Sep 22, 2020, 8:05 PM

#

it might be easier to count unique viewers than come up with alternative wording for "viewers" to explain exactly what it really is

#

just look at how enlistments gets used

barren quarry Sep 22, 2020, 8:05 PM

#

"People currently on the website"

long raft Sep 22, 2020, 8:06 PM

#

but its not - its tabs currently on the website

pure sierra Sep 22, 2020, 8:08 PM

#

its not that im concerned with discerning with the count or description that it could be multiple for one person, more that the number doesnt imply that many people sitting there watching the website or interacting with it , and that it could just be an idle computer background tab

fickle aurora Sep 22, 2020, 8:09 PM

#

have you tried this https://www.php.net/manual/en/function.socket-get-status.php

#

the thing is HTTP does not always keep connection alive, most will be in TIME_WAIT state

#

unless you are streaming data to the client

#

your best plan of action might just be to automatically create sessions for users based on IP and have them time out those sessions if they have not clicked a link in a certain length of time, and then you can just count the number of active sessions

#

the most popular way to do that is through SQL server commands but you could just parse a simple text file as well

#

for something simple like this you probably don't even need to design a login system

fickle aurora Sep 22, 2020, 8:33 PM

might be a good resource if you want to check the return value of socket status

fickle aurora Sep 22, 2020, 8:39 PM

#

yeah I don't know if you can return the value of the client connection status

#

but you can be assured TCP has not changed much since 1984, the return values are pretty much all there as they were

#

if TCP was updated like windows was every few weeks, it would be impossible to have a functioning internet

long raft Sep 22, 2020, 8:45 PM

it's a different socket type

it's not even reliant on tcp/ip

Handling connection loss with websockets

I've recently set-up a local WebSocket server which works fine, however I'm having a few troubles understanding how I should handle a sudden loss of connection which neither the client or server

fickle aurora Sep 22, 2020, 8:48 PM

#

it is 100% tcp, there are just 2 main protocols; TCP and UDP, but the vast majority of things use TCP

#

this whole "websockets" thing is not on the same layer

#

websocket is literally on application layer in networking, TCP/UDP are on a lower layer

#

when you load a webpage, you basically go through that entire diagram all in just a few seconds

#

the final result is TIME_WAIT and eventually the socket will close

#

you can verify this by going to command prompt and typing netstat -a

#

if you type netstat -a in command prompt, you will see all the TCP and UDP connections from your computer, some will be to websites, one or two for discord, etc

#

the diagram I took a photo of and posted above will disseminate the information listed under the "State" column of netstat command

#

however, this is the problem with web pages is that the socket never stays alive, unless you are streaming notifications/push data to the client with node.js or something like that

#

if you are confused about those things that show [::] in netstat, it is unicast in ipv6

long raft Sep 22, 2020, 8:57 PM

#

you should look up what websockets are

#

we are not talking about berkley sockets

fickle aurora Sep 22, 2020, 8:57 PM

#

windows seemed to have followed using brackets around ipv6 addresses ever since windows 95 when ipv6 could be added through an update

#

yes websockets have not replaced tcp if that is what you think

long raft Sep 22, 2020, 8:58 PM

#

i dont think that, and i didnt say that

fickle aurora Sep 22, 2020, 9:02 PM

#

I get my information from textbooks as much as possible because the internet is still largely filled with misinformation

long raft Sep 22, 2020, 9:02 PM

#

It's weird to think windows 95 would have supported ipv6 considering it wasn't invented until 98, you have a citation on this?

fickle aurora Sep 22, 2020, 9:02 PM

#

I am the citation, I used ipv6 in windows 95

long raft Sep 22, 2020, 9:02 PM

#

Lol

#

Sure you did

fickle aurora Sep 22, 2020, 9:02 PM

#

and it was around much longer than 1998

#

yes there was a way to implement ipv6 using hurricane electric's tunnel because most ISPs did not support ipv6 natively

long raft Sep 22, 2020, 9:03 PM

#

yea like in 2005

fickle aurora Sep 22, 2020, 9:03 PM

#

HE was around a lot earlier than that

long raft Sep 22, 2020, 9:04 PM

#

theyre an ISP, of course. but they werent offering ipv6 tunnels in 1995

#

Ah well check that out: Sometime in 1998 Microsoft Research releases its first trial version IPv6 protocol stack, which can be installed on Windows 95 or Windows 98 to provide limited IPv6 support.

fickle aurora Sep 22, 2020, 9:06 PM

#

I see you are just skimming information off wikipedia to use to argue with people, when in fact you don't really do proper research

long raft Sep 22, 2020, 9:07 PM

#

Please don't lecture me on research

fickle aurora Sep 22, 2020, 9:07 PM

#

yes but you could use ipv6 on other systems before 1998

long raft Sep 22, 2020, 9:07 PM

#

You make up stuff all the time

#

Well they did not release that code before 1998, but ok

fickle aurora Sep 22, 2020, 9:07 PM

#

yes hurricane electric had the code originally

long raft Sep 22, 2020, 9:07 PM

#

It did work on windows 95, you were right. I thought it might be a scenario like that so I asked for a citation

#

You think hurricane electric was using windows servers for their tunnels? I doubt that

#

Surely microsoft wasn't the first ipv6 stack. There must have been earlier ones on Unix

fickle aurora Sep 22, 2020, 9:08 PM

#

no they had the code for people to get ipv6 connectivity on windows 95

#

microsoft didnt have it until later

long raft Sep 22, 2020, 9:08 PM

#

god damn, ya know, maybe they were

fickle aurora Sep 22, 2020, 9:08 PM

#

afaik hurricane electric was one of the biggest contributors to ipv6 development

long raft Sep 22, 2020, 9:09 PM

#

that's pretty early to adopt a draft, microsoft was crazy cutting edge to put that into a consumer OS like windows 98

#

anyway, I don't care about ipv6

#

we were just talking about how to uniquely count viewers using a websocket

fickle aurora Sep 22, 2020, 9:10 PM

#

yes you could do it with a tcp socket check but like I said the flaw in that is most tcp connections are always waiting

#

the best way would be probably create a temporary session for every IP that retrieves a web page and then have a timeout check run every time a page is accessed to remove sessions that are more than a defined number of minutes old

#

then simply count the number of sessions

long raft Sep 22, 2020, 9:12 PM

#

I thought so too. But it's not perfect

pure sierra Sep 22, 2020, 9:18 PM

fickle aurora Sep 22, 2020, 9:20 PM

#

well if you designed an admin portal for it, it may be useful to you to list stuff like the TCP states that are stuck on SYN for example, because robots/scripts online often use SYN/ACK attacks where they request a webpage but then they ignore the rest of the data, then send another request, ignore the rest of the data and continue like this in a loop

long raft Sep 22, 2020, 9:20 PM

wut

fickle aurora Sep 22, 2020, 9:21 PM

#

sometimes it is not bots but it can be people with bad internet connections

#

if you are already using mitigation like cloudflare then it is probably not a problem

#

and this is also why satellite internet sucks so much

#

half of the websites on the internet think your computer is a bot when you connect on satellite from a remote area

long raft Sep 22, 2020, 9:23 PM

#

why would bots use such an expensive network?

fickle aurora Sep 22, 2020, 9:24 PM

#

bots usually use top of the line data centers but they act as if they can't fully load a webpage, because that is essentially how the attack works

pure sierra Sep 22, 2020, 9:24 PM

#

@long raft i got it

fickle aurora Sep 22, 2020, 9:25 PM

#

satellite has a latency problem which is why SYN/ACK in the tcp handshake has such a big lag on satellite

#

the server technically sends both an ACK for the first part of the handshake and in the same packet it also sends a SYN to check the client for a response

#

at the beginning when you request a web page your client sends a SYN

long raft Sep 22, 2020, 9:29 PM

@pure sierra what did you get?

pure sierra Sep 22, 2020, 9:29 PM

long raft Sep 22, 2020, 9:30 PM

i dont even know which one you mean

long raft Sep 22, 2020, 9:31 PM

#

oh

fickle aurora Sep 22, 2020, 9:31 PM

#

there I hope it is easier to see

#

generally web pages load pretty fast, after they are done loading, there is no longer an open connection which means another client can connect

#

of course, scale this up to see the effect

#

on satellite internet (not bots, just poor blokes in northern canada) the 2 second latency of having a signal travel millions of miles from earth to space and back, and going through various routers, the latency makes your connection stay open for a long time, and some things such as cloudflare think that your computer is a bot because it detects a non-response from the server's SYNACK packet

long raft Sep 22, 2020, 9:35 PM

#

its not millions of miles

#

hundreds of miles

fickle aurora Sep 22, 2020, 9:36 PM

#

that is an exaggeration, but yes

#

if you happen to be someone in demand for the big bucks at mines in northern canada working on expensive systems, you will get to see just how latency is a real problem when you have to live there

#

thankfully there is going to be low to earth systems now, which the latency has gone down to about 600ms for a one way trip packet

#

I think SpaceX is advertising even better latencies, but I am skeptical on that

fickle aurora Sep 22, 2020, 10:03 PM

#

so anyway if you want to work with socket programming, I would recommend something like ISBN #9780134900124 or maybe a newer edition - that is the one I use and if you go through all the examples, you can make your own server/client programs on a shell account somewhere with gcc access

I got live users so I need to send callbacks immediately with sockets

cron min 1 minute, thats enough

barren quarry Sep 23, 2020, 2:34 AM

Map updates cost me 210gb bandwidth usage monthly

? just querying the api ?

Yes

likely thats where a bunch of my data is going too

500gb

barren quarry Sep 23, 2020, 2:36 AM

#

One dynamic endpoint is like 4kb of json

long raft Sep 23, 2020, 2:37 AM

#

every 3 seconds? wow thats high

#

do the api servers support gzip/deflate/brotli?

barren quarry Sep 23, 2020, 2:37 AM

#

I should probably change to 5

#

No idea

long raft Sep 23, 2020, 2:38 AM

#

because you might need to specifically request the gzipped version in your query

#

it would reduce data by like 2/3

#

i mean when theres an actual update

#

so like an http request header can include the compression formats youre willing to accept, and usually gzip is supported

pure sierra Sep 23, 2020, 2:39 AM

#

i doubt it

long raft Sep 23, 2020, 2:39 AM

#

the http header "Accept-Encoding: gzip,deflate"

#

i just think theres a possibility it might work because the web server supports it shrug

#

in fact i should do that for logiwaze

#

oh evidently its automatic for ajax calls

pure sierra Sep 23, 2020, 2:42 AM

we dont use ajax, but me curl

can u tell if it works ?

long raft Sep 23, 2020, 2:45 AM

so on logi waze it says request
Accept-Encoding
gzip, deflate, br

probably not brotli tho heh

their api may not even be a web server as such, and a dedicated script

long raft Sep 23, 2020, 3:26 AM

#

software was being offshored??
so you went into electronics?

#

have you seen the data since?

fickle aurora Sep 23, 2020, 3:26 AM

#

my instructor said I would never hope to get into UI design until I finished my degree and got 10+ years of experience

long raft Sep 23, 2020, 3:27 AM

#

hmm i dont know any ui/ux designers

fickle aurora Sep 23, 2020, 3:27 AM

#

yeah I have seen the data.. everything is offshored, even electronics - but there's far less offshored because electronics is much more difficult

long raft Sep 23, 2020, 3:27 AM

#

i dont know if software engineering is being offshored, but its definitely growing in about every country

#

i think a lot of electronics are done in china malaysia and japan

#

i dont think its accurate to say the labor in those countries is cheaper because theyre not as smart and cant do more difficult things

fickle aurora Sep 23, 2020, 3:29 AM

#

my class was full of meatheads literally, these guys had such a hard time with digital logic and I could never understand why we were using logic gates when we could simply just use a microcontroller with a simple C program uploaded to it

long raft Sep 23, 2020, 3:29 AM

#

i think electronics, of all things, dont have much cultural context (like speaking english) so its easier to sell those products internationally

#

just pointing out that china can also do difficult work

fickle aurora Sep 23, 2020, 3:30 AM

#

yeah the thing is with electronics, it's mostly digital now, a lot of the digital logic that the courses have is literally outdated in a way because everything is done with C

long raft Sep 23, 2020, 3:30 AM

#

what theyre not great at is iterating with an english speaking customer to design software

#

ya know i think thats why india is growing in software so fast

fickle aurora Sep 23, 2020, 3:31 AM

#

the irony is that there is very little definition of digital vs analog - we were taught digital is like DC pulses, and analog is sine wave, but you know, an awful lot of digital data is sent on sine waves especially in RF modulation (wireless)

#

you can transfer a heck of a lot more data more efficiently using analog instead of digital

long raft Sep 23, 2020, 3:32 AM

#

you cannot compress analog losslessly like digital

#

or selective loss

#

this is how the us saved tons of bandwidth on television broadcasts

fickle aurora Sep 23, 2020, 3:33 AM

#

the thing is digital has latency, analog does not

long raft Sep 23, 2020, 3:33 AM

#

im not sure thats a problem for most use cases, the latency is low

fickle aurora Sep 23, 2020, 3:33 AM

#

even ADC does not cause latency, but converting it to serial data introduces latency

#

the whole idea with wireless is that you can manipulate the sine wave to create real numbers instead of just 0 or 1, so you effectively transfer bytes instead of bits

long raft Sep 23, 2020, 3:39 AM

#

i would assume that requires more precise ADC and more bandwidth use (like for radio waves). theres always tradeoffs, right?

fickle aurora Sep 23, 2020, 3:39 AM

#

yes

#

I had to build on my knowledge outside college though, we never did RF in college and I am not willing to fork over millions for the degree, so I basically self taught that stuff, and one of the most valuable things to me is university booklists, those are like gold for me

#

couldn't care less for a degree if I can whip up my own proprietary hardware product and get it to market

#

I spent my time driving class A and spending my off time reading and buying electronic components to build random circuits

long raft Sep 23, 2020, 3:42 AM

#

ive got an idea, and ive never seen it done, and i cant imagine why not

#

its right up your alley maybe, tell me what you think...

#

say you live in an apartment, and you want to put a lamp on a different wall socket, but you cant really mess with the apartment wiring

fickle aurora Sep 23, 2020, 3:43 AM

#

the most exciting thing is making oscillator tank circuits that can be used to set a frequency, then you just modulate that frequency to transmit data

long raft Sep 23, 2020, 3:43 AM

#

i would like a device that i plug into the wall socket connected to the light switch, and i plug another radio connected device into a different socket, and they become linked

fickle aurora Sep 23, 2020, 3:43 AM

#

yes you can get around much of the laws by keeping your projects under 30 volts and make them battery operated

long raft Sep 23, 2020, 3:44 AM

#

so when i turn on the power at the switch, the connected socket recognizes activity, and transmits to the other socket to complete the circuit

#

if i could buy this, i would buy so many.

#

you can buy a wireless light switch. yes. but many people dont even know how to turn their circuit breaker switches off

fickle aurora Sep 23, 2020, 3:45 AM

#

you have to get into the extra low voltage classification, but there's still other things such as RF is regulated by industry canada, but you are exempt if you are more than 10km from an airport and are doing lab work

long raft Sep 23, 2020, 3:45 AM

#

but you know the lame part about making anything is im sure this is already patented, even tho whoever patented it isnt making or selling them

#

anyway, is there some reason this doesnt exist? some electronic problem im not seeing?

fickle aurora Sep 23, 2020, 3:46 AM

#

yeah anything that plugs in the wall requires certification and anything that does RF modulation requires extra certification

long raft Sep 23, 2020, 3:46 AM

#

i buy plenty of wall socket devices, they all manage to get certified.

#

certification cant be the reason this doesnt exist

fickle aurora Sep 23, 2020, 3:46 AM

#

you can get away with USB though, but you have to use a microcontroller to request more than 5 volts

long raft Sep 23, 2020, 3:47 AM

#

if you have a good idea and a working prototype i cant imagine its that hard to get certified

fickle aurora Sep 23, 2020, 3:47 AM

#

200 ohms resistance across the data pins tells any device that your device is a charger, if you are making like a battery bank for a cell phone

#

but it also just registers it for 5 volts

#

for the advanced charging, lets say you want to provide 12 volts to charge a samsung phone or something, you need to send signals on the data line instead of just a 200 ohm termination

long raft Sep 23, 2020, 3:49 AM

#

no no, i want it to power a wall socket

#

youre talking about usb and phones now

fickle aurora Sep 23, 2020, 3:49 AM

#

otherwise if you do not use the 200 ohm resistor, even for basic 5v, the phone will ignore the USB connection to protect itself from accidents

umbral mulch Sep 23, 2020, 3:49 AM

#

lol

#

that sounds like a cool idea

long raft Sep 23, 2020, 3:50 AM

#

i just know if you could buy these at a cheap store every old person would stock up on them

fickle aurora Sep 23, 2020, 3:50 AM

#

yeah the thing is certification is really expensive

long raft Sep 23, 2020, 3:50 AM

#

it seems so possible, why doesnt it exist!

#

this is as seen on tv stuff!

umbral mulch Sep 23, 2020, 3:50 AM

#

It would be kinda like a simplified home control system

#

but for 1 socket

fickle aurora Sep 23, 2020, 3:50 AM

#

chinese manufacturers cheat by using CE, but CE is not legal here actually (though most CE certified stuff is not caught by customs anyway)

#

CE allows manufacturers to self-certify, it's a total joke really

long raft Sep 23, 2020, 3:51 AM

#

the number of times i just wanted a light switch to control a different socket without running new electric cable

umbral mulch Sep 23, 2020, 3:51 AM

#

ye

fickle aurora Sep 23, 2020, 3:51 AM

#

both US and Canada don't recognize CE certification

#

I admit I have made a lot of cool 120V and even 240V stuff but I would never hope to use them outside my little workshop

long raft Sep 23, 2020, 3:53 AM

#

it doesnt even seem dangerous, its just some micro controller triggering a relay

fickle aurora Sep 23, 2020, 3:53 AM

#

not all of it is microcontroller based

long raft Sep 23, 2020, 3:53 AM

#

the worst possible scenario is the socket is always on (which it normally would be)

fickle aurora Sep 23, 2020, 3:53 AM

#

though to be honest I love the idea of making everything with fancy controls

long raft Sep 23, 2020, 3:53 AM

#

theres power sources available for both devices, i just ... i cant understand why this isnt already a thing i can buy

fickle aurora Sep 23, 2020, 3:55 AM

#

so what you are looking for is just a panel with toggle buttons

long raft Sep 23, 2020, 3:55 AM

#

anyway thats my million dollar idea

#

no i definitely dont want a panel with toggle buttons

fickle aurora Sep 23, 2020, 3:55 AM

#

I'll go back and read what you were writing

long raft Sep 23, 2020, 3:56 AM

#

imagine a transmitter and a receiver, they both plug into a wall socket, like a pass-through plug

#

when the power is triggered on one socket, it tells the other socket to turn on

#

so i can move my lamp to the other side of the room, plug in both devices, and my switch controls the lamp somewhere else now

#

or i can make it work 2 lights at once on different sockets

#

every single person living in an apartment would buy at least 1

#

or offices...

fickle aurora Sep 23, 2020, 3:58 AM

#

I mean that would be fairly simple to make with RF and 1 relay

long raft Sep 23, 2020, 3:58 AM

#

i have never been able to find one on the market

#

theres a bunch of junk thats like half way, like you can replace your light switch with a radio transmitter, and replace your socket with the receiver

#

but thats not something most people are capable of doing

fickle aurora Sep 23, 2020, 3:59 AM

#

I like the idea though but that would take multiple certifications

long raft Sep 23, 2020, 3:59 AM

#

or theres remote controls, but i want to use my existing nice switch, or maybe i want 2 lights controlled by the switch

#

so i imagine, it would easily have a market, it wouldnt be too hard to collect the money to certify it from investors, but i imagine its already patented

#

people patent everything and then never make it

fickle aurora Sep 23, 2020, 4:00 AM

#

I am thinking something like that would even be great for 50 amp stove outlets

#

to be able to turn the whole stove off with the light switch

long raft Sep 23, 2020, 4:00 AM

#

the magic of it is that its easy enough for anyone to install

fickle aurora Sep 23, 2020, 4:01 AM

#

the thing is you'd have a massive relay for that

long raft Sep 23, 2020, 4:01 AM

#

i dunno, my alexa smart socket thing is ... so small

#

its like a match box

fickle aurora Sep 23, 2020, 4:01 AM

#

and would need a fan to cool it off because they generate heat

long raft Sep 23, 2020, 4:01 AM

#

its basically doing that with 802.11

#

why heat? again, my alexa device doesnt seem to need a fan

#

ok its more the size of a matchbox car, not a matchbox

fickle aurora Sep 23, 2020, 4:02 AM

#

yeah but 50 amps at 250 would use a pretty big relay with overheaters to be compatible with induction stoves

long raft Sep 23, 2020, 4:02 AM

#

oooh for the stove you mean

#

yea i would only need a 20amp one

fickle aurora Sep 23, 2020, 4:02 AM

#

that would be a more special one, thinking big already

long raft Sep 23, 2020, 4:03 AM

#

well you can have the idea, i wont sue lol

#

god i would surely love to buy one tho

fickle aurora Sep 23, 2020, 4:03 AM

#

to make it cost effective would require a white van salesperson

#

for all the people who said LEDs can't generate heat... welcome to my lab where I turn the potentiometer down to 0 ohms and make the cob LED into a smoke generator

#

makes them shine bright though if you use higher current, but also produces a lot of heat

long raft Sep 23, 2020, 4:12 AM

#

less than a regular incandescent tho, eh?

fickle aurora Sep 23, 2020, 4:12 AM

#

they usually burn up before they get to that point

#

interestingly, they have never caught fire even with 120 across them

#

one project I made was 40 LEDs in series connected to 120, because each one dropped enough voltage that all of the supply voltage was used for all 40 of them

#

of course for one LED you wouldn't even see it turn on, you would hear a pop and a burn mark on the board

#

you can produce an amazing amount of light with those and they are like 3 cents each on ali

#

it saddens me when I see LED bulbs for such high prices when they are so dirt cheap to make, the problem is the cost of certification

@pure sierra so the bright green spots on the control map indicate its recently become colonial? It feels like the weak color and strong color are backwards

lunar cobalt Sep 23, 2020, 7:35 AM

@long raft on your electric thingy, I think I remember seeing something like that at Home Depot. There was a light switch (you had to rewire the switch at minimum but that’s pretty easy), and it could then be linked to multiple smart “outlets” that you just plugged into the existing output like you would a cord but with 2 connectors

long raft Sep 23, 2020, 9:06 AM

#

yep, have to rewire something

#

but thats why it wouldnt sell on TV

#

there are complicated ways to do it, i just cant believe why something easier doesnt exist

#

and the way network devices can communicate over the circuits, if a device could signal through the hardware instead of radio it would be even cooler

doesnt check the chat for a day, 400 technical messages

#

lol

fickle aurora Sep 23, 2020, 4:48 PM

#

well there is a very nice kitchen experiment you can do to answer part of Derp's quest for this new idea on measuring if one device is running and then turning on other plugged in things based on the state of the master plugged in device

#

it's fairly safe, all you feel is just a buzz, but if you take a strong magnet like a rare earth (neodymium) magnet and place it anywhere along the electrical cord of a kettle or microwave (or any high current device) and then run that device at full power, you can feel the current in the magnet because the high current will create a magnetic field - since it's AC current, the field will change at a rate directly proportional to the frequency (60Hz) and you get to feel it as a buzz

#

you get the same effect with any current, but they won't produce enough eddie currents/fields to feel with a magnet in your hand much like a 10-15 amp device will, but you can use this by wrapping a wire around the cord somewhere and tie one end to common ground with the other end tied to the base of a sensitive transistor

#

essentially what you would be creating in this is a mini current transformer - you can buy them already in a unit as an electronic component for pennies, but it is also great to experiment and see just how it all works

#

in addition, if you use a transistor with a good linear output, you can also use this as a way to measure the current in the main appliance because the strength of the magnetic field on the appliance's live wire (hot as opposed to neutral or ground) will be directly proportional to the current that appliance is drawing, which means your current transformer will of course increase or decrease the current sent to the base of the transistor, giving you a linear output directly proportional to the current draw of your appliance

#

and - of course - with this kitchen experiment you can understand why it's very bad to put your data wires beside high current drawing power cables... (though you can of course, wrap a bare wire over the power cables and tie that wire to ground, which is exactly what that metal foil is for inside high quality network cabling, that foil should also be connected to ground somewhere of course)

lunar cobalt Sep 23, 2020, 5:13 PM

#

@long raft The reason it doesn't work over power lines is because when you flick a switch you're mechanically closing a circuit, and so the only way to detect that would be to have that circuit also run power to a different place, which is what is already in a lot of houses for outlets. You can't really communicate stuff over electrical lines since they're just running power. You'd need to "read" the output of the power line like Widallan said, and that gets relatively complicated.

fickle aurora Sep 23, 2020, 5:15 PM

#

well you can actually send signals through the live wire theoretically by superimposing frequencies

#

sort of like this basically https://en.wikipedia.org/wiki/Broadband_over_power_lines

Broadband over power lines

Broadband over power lines (BPL) is a method of power line communication (PLC) that allows relatively high-speed digital data transmission over the public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range and different technologies from o...

#

this is kind of how DSL works really, you have one wire with hundreds of different frequencies on it - in this case, we could superimpose a different frequency on the live wire in a house and then filter out the 60Hz frequency, leaving us with the superimposed frequency we want

lunar cobalt Sep 23, 2020, 5:18 PM

#

not gonna work in my house that's for sure, wires there are fucked

#

as in, "outlet on one side of the house is connected to 3 outlets on the far end of the house" for some reason

fickle aurora Sep 23, 2020, 5:18 PM

#

lol

lunar cobalt Sep 23, 2020, 5:19 PM

#

Need to turn off the power to rewire something? Just trip the main breaker, only way to be sure

fickle aurora Sep 23, 2020, 5:21 PM

#

yeah so to detect when something is turned on, you can use a current transformer like I explained above, you'd basically detect current draw so it wouldn't really detect everything that is turned on unless it reaches a certain current threshold

#

in a way that might be an advantage because many TVs have soft power systems that draw microamps of current when they are turned off, drawing just enough power to run a microcontroller interrupt pin and to power a diode to detect input from your remote control (and of course interrupt from the physical power button on the TV)

#

well computers, TVs, kettles, stoves, coffee makers, pretty much everything now uses soft power

#

on an ATX motherboard for example, the interrupt on the motherboard detects when you short the power pin to ground, which causes current to flow and I can imagine that is detected by having the base of a transistor connected to that power on pin

summer bobcat Sep 23, 2020, 5:31 PM

#

damn I love reading this channel

fickle aurora Sep 23, 2020, 5:39 PM

#

I love how broadband over powerline was dumped by all the other industries because they were worried about interference, yet it's far less interfering than wireless would be, I mean, just the nature of the signal being in a wire instead of all around the air to me makes more sense in terms of preventing electrical interference

#

it also means you'd have to redesign everything that plugs into 120V sockets though, to filter out all the frequencies you don't want

#

anyway, it's good for LAN since I think the frequency is terminated at the
big transformer that provides you with service

lunar cobalt Sep 23, 2020, 5:42 PM

#

yeah most things in 120V sockets dislike it when the power isn't at or near 60hz

fickle aurora Sep 23, 2020, 5:43 PM

#

I wouldnt be surprised if it isnt already done at the carrier level using the high voltage lines

#

there is another cool experiment you can do using a car's ignition system and a high gain antenna to basically create sparks at a frequency picked up by the antenna and filtered with a tank circuit, but technically it is illegal lol

#

back in the early 20th century spark gap radios were banned in most countries because of course a spark is really quite interesting when it comes to electronics, RF and magnetism, it literally acts like a signal jammer

long raft Sep 23, 2020, 5:58 PM

#

Uh they make network adapters you just plug into the wall sockets, Theyve been around for decades

#

hes right, it doesnt work beyond the transformer, too

fickle aurora Sep 23, 2020, 6:09 PM

#

yeah there were developments on BPL in 2004 apparently according to wiki but they were discontinued because of opposition by many other industries

#

but yes they are widely available for LAN home use

long raft Sep 23, 2020, 6:52 PM

#

i think they have been around longer for telephone lines

#

the moment the switch is activated there would be power to both devices...

timber onyx Sep 26, 2020, 6:44 PM

#

radios in general are really interesting to me

#

you can literally make an AM receiver radio with a crystal, a piece of metal and an earpiece

#

don't even need a power source

#

and it all seems complicated until you realize a radio is just a piece of metal that transforms radio waves into electricity and the rest is just to filter the exact frequency you want.

coral sundial Sep 28, 2020, 2:46 PM

Its the I/O port of the board. short for Pin IN id like to think

#

X is for which register

fickle aurora Sep 28, 2020, 5:34 PM

#

funny thing is there would be less typing in that if you just used assembly

jovial lake Sep 28, 2020, 5:35 PM

#

c

#

arduino?

fickle aurora Sep 28, 2020, 5:36 PM

#

it looks more like atmel or mplab but it could be any IDE with GNU AVR C compiler in it

#

I use XC but quite similar, though the features are vastly different between compilers

#

but what his functions were doing (from what I can read there in the screenshot) is basically reads whether a pin is input high or low, which I mean, you can just read the PIN register and then branch if bit is set in assembly, which is like 2 short lines of programming instead of massive C functions :D

#

so to get started the best thing really is to grab the datasheet (I will use 328p as an example) and go to the section called "Register Summary" which is often near the end of the file - table of contents will often have a clickable link to it

#

the address numbers in brackets are the ones you want to focus on, some of the registers have another number in there, but to get started, just focus on the ones in brackets, so in this case if you were using PINB you can simply call up 0x23 to see which pins on port B are high or low, like this: IN R0, 0x23 which would store the value of the pins on PINB into general purpose register 0 (aka working register)

#

so one thing people are often confused by is how to make if statements in assembly, but in assembly you have more flexibility - we can ignore all the rules about programming and simply tell the program counter exactly what to do line by line, and where we want to loop from or branch out to

#

so we don't really have an if statement, we kind of make our own from scratch, and I like to use the SBRC instruction for this in almost every situation - not all CPUs have the same instructions but this one seems common among all the AVRs, it tells the CPU that if the bit in the register given is cleared (0), then skip the next instruction... essentially your next instruction will be your branch for if it is set (1, or like I say, 1 is usually true)

#

  SBRC R0, 0 // 0=PINB0, 1=PINB1, 2=PINB2, 3=PINB3, 4=PINB4, etc...
  RJMP PINBx_INPUT_IS_HIGH``` so this is a good example, you can replace all those big C functions with something quick and easy like this

#

of course, if you instead wanted to check if a pin was held low (or grounded), you could instead change the instruction from SBRC to SBRS which skips if bit is set: IN R0, 0x23 SBRS R0, 0 // 0=PINB0, 1=PINB1, 2=PINB2, 3=PINB3, 4=PINB4, etc... RJMP PINBx_INPUT_IS_LOW

#

RJMP is just an instruction that tells the CPU to modify the program counter to point to the line where the specified label is at and ignore everything up to and including the colon plus any whitespaces (so you can have the instruction placed anywhere after the colon)

#

i think the topic just hit all his dopamine spots

fickle aurora Sep 29, 2020, 12:36 AM

#

well I am surprised all these university students are having trouble reading a few paragraphs wardenlol

#

I think derp made a syntax error, because the way the syntax goes is value = <condition>?<value if true>:<value if false>; in C at least

#

if you simply just put x variable in there instead of writing the condition x==1, then what can happen with some compilers is that it can return the property of whether x is assigned a value or not, as in, some compilers don't consider 0 to be null, some like for example, XC that uses C99 standard, or at least anything that is ANSI C standard will require that you actually put a conditional statement in there

#

so if you declare x = 0;, sometimes if you use a condition such as if (x) { } then some compilers will return true because that compiler may be checking whether x has been initialized (assigned a value), so you should get into the habit of always using if (x==1) {} or even if (x>0) {}

#

there are lots of tips people can give you, such as for example, always increment instead of decrement wherever you can - why? internally, adding is just shifting bits... subtracting requires more CPU time because a CPU can't really subtract a number ... it has to get the complementary value and then add 1 to the result, then get the complementary value of the result which is how it performs subtraction on the hardware level - unless of course the math operation is performed by the math co-processor, which does not use binary to perform math

#

some compilers accept while (;;) and others will not compile unless you use while (1), another example of a situation where it depends on what specific compiler you are using

coral sundial Oct 2, 2020, 9:15 PM

#

I dont know some kind of small transmission DC motor

timber onyx Oct 2, 2020, 9:15 PM

so it's not a stepper motor

#

if you want control you gotta use a stepper motor

coral sundial Oct 2, 2020, 9:17 PM

#

nah

#

thats for super precise control

#

I just need to know wheter its opened or closed something

timber onyx Oct 2, 2020, 9:21 PM

#

alright well if you fixed your issue it should be ok. just remember to be careful what inputs you're using, some drivers literally insta die just for activating the controlling side before the motor side

#

and as a useful tip, dont use the dangling jumper cables if your circuit is all on a breadboard, cut pieces of wire and put them on the breadboard instead. becomes way less annoying to figure out what's connected to what

fickle aurora Oct 3, 2020, 3:58 AM

#

@coral sundial you can just basically buy the chips in bulk and solder them directly to prototype boards but make sure you stock up on 15pf and 22pf, and maybe 0.1uf ceramic capacitors, 100nf/1uf/10uf electrolytics and 16 and 20mhz crystals as well esp if you are using stuff like the 328p - also should maybe consider investing in the atmel ICE basic kit if you are gonna do a lot with AVR ... for resistors you can go for the resistor sample books so you have a wide variety and then also perhaps stock up on a lot of 10k and 1k resistors and maybe 470 ones for LEDs ... buying a big bag of cheap BC547 NPN wouldn't hurt either

#

there are some guides around explaining how to set up your own ICSP header and how to set up a reset button with a short ground pulse for when you need to upload a program to the chip

#

basically you need to put positive rail through some resistance to the reset pin for programming it, but you need a pushbutton that shorts it to ground with a ceramic capacitor across it, so that as soon as you click to upload a program, you can then give the button one press and it will then accept the data transfer ... shorting the reset pin to ground is what makes the chip accept your upload - but the timing has to be fairly precise which is why you need to pick the right capacitor, but it is explained in the datasheet which cap to use ... if it doesnt work, it will make you think that the chip is dead when it is in fact okay, just that you need to get the timing of the reset proper

#

another common one that gets me sometimes is don't forget to power the rest of the Vdd pins and ground the rest of the Vss pins, as there are often multiples and if you miss one it will also not work for that reason

timber onyx Oct 3, 2020, 4:44 AM

#

who needs to buy anything when you have infinite free resistors and capacitors you can steal from your school

timber onyx Oct 3, 2020, 5:03 AM

#

and some inputs arent activated by ground, you gotta make sure you read the datasheet. always. i've fried some ships for not reading correctly

#

some manufacturers are nice and even give you example circuit diagrams for their stuff

#

i know i had to read the texas instrument examples many times to remember how to use an LM117

#

but god it feels good to figure out how a component works, feels like being an archeologist digging up ancient runes

#

though that might just be me

coral sundial Oct 3, 2020, 9:19 AM

#

#

#

After that...

timber onyx Oct 3, 2020, 10:17 AM

#

you could figure out by yourself how the chip works. i had to do it for my first job in the domain.

#

it just requires reading the datasheet a lot and looking up every word you dont understand

#

understanding every port..

#

it's pretty time consuming but you get to really understand how the chip works

like really, buy a fucking pen

you just have to put a dab on the board, put the wire in place and heat the solder

timber onyx Oct 4, 2020, 3:07 AM

#

the beeping mode?

#

you mean continuity mode?

#

yeah what that does is create a small current in the probes so that when the circuit between positive and negative lead closes the multimeter beeps

#

if you put it on an LED it'll light up faintly because of the small current

#

some multimeters have a special diode check mode just for this reason

fickle aurora Oct 7, 2020, 10:49 PM

#

the beep mode on a multimeter is often for testing diodes on most multimeters, depends on which one you have, it will have a diode symbol on the beeping mode selection - it is basically great for testing LEDs without the need for current limiting also since they are of course diodes - you can also test transistors and such, but there are better testers for transistors

#

the beep won't work if the wire has high resistance like over 5k or so, so you need to use resistance mode and select the proper range if you are checking resistances above 2k or so ... diode mode can give resistance readings up to around 2k for most meters

#

if your solder joints break, using proper resin flux will make those joints very solid - a good solder joint won't break, but there are some cases where you don't want to use flux, like with sensitive components or some BGA stuff, but that's also why you can easily pry off components from most mass produced PCBs because robotic machines that make most circuitboards often don't flux the board and the connections can easily break

@lunar cobalt @barren quarry just got word that a player with the 'failed to download profile error' got it working by changing his steam display name. i suspect this corrected a problem with his profile.

My guess is it’s what you told me about how you don’t have ipv6

pure sierra Oct 14, 2020, 7:06 PM

#

u dont need ipv6, it runs off v4

#

infact ipv6 is likely to get in the way

fickle aurora Oct 14, 2020, 7:06 PM

#

you should almost always disable ipv6 in network connection adapter settings unless you are sure you need it, because windows will try to use it to resolve addresses before it tries to resolve with ipv4

pure sierra Oct 14, 2020, 7:07 PM

#

@fickle aurora yes

fickle aurora Oct 14, 2020, 7:07 PM

#

it makes a big problem down the road but I think on most linux/mac systems you are fine with ipv6 enabled

#

just windows has this problem and anything that uses windows sockets, such as .net applications (C# apps ported to linux for example)

#

sadly microsoft couldn't properly implement ipv6 back in 1998 and even today still has not figured it out despite their billions of dollars

pure sierra Oct 14, 2020, 7:09 PM

#

ive had problems with it on my linux vps, where services will try and bind to it by default, and then become unreacheabale

fickle aurora Oct 14, 2020, 7:10 PM

#

works fine in freebsd 4.8

pure sierra Oct 14, 2020, 7:10 PM

#

im not saying it doesnt work, just that it can get selected as the wrong iface

fickle aurora Oct 14, 2020, 7:10 PM

#

well, I admit, most people don't use 4.8 now, but people who still remember the words "uptime" and "stability" still use it

#

funny thing is, windows 10 has great stability, but due to forced updates, it's worse than windows 98 loaded with viruses and malware in uptime

pure sierra Oct 14, 2020, 7:12 PM

#

win10 sucks, im still using 7

fickle aurora Oct 14, 2020, 7:12 PM

#

I would, but I have more than 190GB of memory

pure sierra Oct 14, 2020, 7:13 PM

#

u can see in the logs they dont use ipv6: [2020.10.13-19.20.45:129][576]LogLwsWebSockets: Lws(Notice): Creating Vhost 'default' (serving disabled), 3 protocols, IPv6 off

fickle aurora Oct 14, 2020, 7:15 PM

#

if the site resolves to an IPv6 address, and you have ipv6 enabled in your adapter settings, windows will try to connect via ipv6 (because why not, it's newer than ipv4) even if it does not actually have an ipv6 address - this is because there is often compatibility via ipv4 mapped ipv6 addressing

#

the idea back in the 90's was that all ISPs would switch to IPv6 permanently - it never happened

pure sierra Oct 14, 2020, 7:16 PM

#

@fickle aurora what do u make of the first error he gets , as likely that is the one that starts all the rest
