[0:06] <BCMM> "The Pirl Charger performs a digital handshake that detects how much the device can handle and delivers that." right but with what protocol? there's a whole bunch of competing ones!
[0:07] * Hoogvlieger (~Hoogvlieg@541A8CEB.cm-5-3c.dynamic.ziggo.nl) has joined #raspberrypi
[0:07] <BCMM> if it only does one, and my phone only does another one, that's useless. as it stands, it's uselessly vague

[0:08] * swift110 (~swift110@unaffiliated/swift110) Quit (Remote host closed the connection)
[0:09] <BCMM> more relevant to the pi, the flexible input is not actually a good feature. it means you've got two voltage conversion stages now, with the corresponding loss of efficiency
[0:10] <BCMM> the one really nice thing is putting a margin of error on the output voltage, though. that's an actual problem with using typical chargers to power a pi

[0:42] <ali1234> it won't do anything for a Pi anyway because Pi doesn't support any type of fast charging. those up the voltage, not the current.
[0:42] <ali1234> pi will just explode if you put 15V into the USB port
[0:42] <BurtyB> :)
[0:43] <ali1234> it does look like a neat device though, if you have lots of fast charge devices and they are all different (assuming this can actually support multiple protocols)
[0:43] <ali1234> i see no reason why it shouldn't

[0:46] <ali1234> apparently this does not support high voltage charging at all
[0:46] <ali1234> so it's useless
[0:49] <BurtyB> unless you have an apple device
[0:49] * immibis (~chatzilla@222-155-160-32-fibre.bb.spark.co.nz) Quit (Ping timeout: 276 seconds)
[0:49] <ali1234> "unless you have a device that limits its own current draw unless you use it with their proprietary charger"
[0:50] <ali1234> samsung does this too
[0:50] <ali1234> also apparently it overvolts the port by 0.15V under load, so it might help with voltage sag
[0:50] <ali1234> that might be useful for Pi
[0:55] * BurtyB has a buck boost board on the way to sit under the pi to fix that one too :)

[5:46] <brianx> if you have a soldering iron, the best pi3b power supply that i've found is those 41 cent chinese dc-dc converters (the ones with the mp1584en chip, not the "mini" ones) and a 1 amp or 1.2 amp wall wart from an old cable/dsl modem or router. old laptop supplies work withthe dc-dc converter too. make the lead to the micro-usb only an inch long to avoid voltage drop over the thin wire.

[5:51] <brianx> 12w is about the minimum output that you want on the wall wart, 14.4w is better. lower voltage will make less heat in the dc-dc converter.

[7:04] <Voop> brianx: the struggle is finding a suitable cable usually
[7:04] <Voop> wiring it direct from a buck converter is ideal for power to the pi
[7:05] <Voop> but not ideal for usability
[7:05] <brianx> at only an inch, the cheapest old charging cable works fine.

[7:06] <brianx> it's never been a problem having a little 2cm x 1.5cm board about an inch away from the pi. it's so small and light that i never notice it.

[7:33] <Voop> ironically i didnt buy them to power a pi, i bought them to step an input signal down
[7:33] <brianx> signal?
[7:34] <Voop> since i couldnt fit a relay in my project. theres probably 10 better ways but this was easy and fast
[7:34] <Voop> yeah 24v signal needed to be 3v to pi
[7:34] <brianx> lol, odd solution.
[7:35] <Voop> have 4 of them left ill probably use for powering pi zeros
[7:35] <brianx> there are bunches of ways to level convert.
[7:36] <brianx> save these for the pi3b. use those crappy lm2596 ones for zeros that don't need the current.

[7:49] <brianx> hook the resistor to 3.3v and the gpio. hook the diode to the gpio and the 24v signal with the line on the package towards the 24v. done. the 24v signal has to be able to sink a mA when low. if it can't, a pull down resistor is needed.

[9:26] <brianx> SovietBeer: 128 threads is no problem, as long as your threads are small enough that they don't run you out of ram.
[9:27] <SovietBeer> brianx: also 200 threads?
[9:27] <SovietBeer> what is the limit (other than ram)?
[9:27] <brianx> the limit should be many thousand.
[9:27] <SovietBeer> this suggests the limit is 238 but that's from 2012 for an older pi https://www.raspberrypi.org/forums/viewtopic.php?p=225735&sid=978c8a7dea6484a720038a7e0b91becc#p225735

[9:40] <Hdale85> Voop: hey look at that it works now :)
[9:40] <brianx> so this is some custom rust code you wrote and you're surprised that spawning 200 threads in rust s nailing your intel i7 to 100%. try not using rust.
[9:41] * lstar (~Fabio@151.20.178.95) Quit (Quit: Leaving.)
[9:41] <SovietBeer> brianx: so are you saying if i spawn the same threads in C, it wouldn't use 100% cpu?
[9:41] <SovietBeer> why?
[9:41] <SovietBeer> rust has no overhead
[9:42] <brianx> because c isn't rust.
[9:42] <brianx> lmao, rust is all overhead.
[9:42] <SovietBeer> but isn't it because there are 200 threads and only 4 cores? isn't that the reason why it's at 100%?
[9:43] <SovietBeer> 8 logical cores but 4 physical
[9:43] <brianx> the appropriate number of threads for optimal performance is not always related to the number of cores.
[9:43] * immibis (~chatzilla@222-155-160-32-fibre.bb.spark.co.nz) has joined #raspberrypi
[9:44] <SovietBeer> sure, but such a vastly larger number could cause high cpu usage, right?
[9:44] <SovietBeer> due to scheduling overhead
[9:44] <SovietBeer> no?
[9:44] <brianx> just the spawning of threads is a lot of work under rust.
[9:44] <SovietBeer> brianx: how is it more work than in C?
[9:44] <SovietBeer> afaik it's the same
[9:45] <SovietBeer> (for the cpu)
[9:45] <brianx> c has only the os overhead per thread.
[9:45] <brianx> rust has the whole rust system.
[9:45] <SovietBeer> rust, too
[9:46] <SovietBeer> what "rust system"?
[9:46] <SovietBeer> :)
[9:46] <brianx> and, yes, scheduling overhead does become a factor at some point.
[9:46] <brianx> rust.
[9:47] <SovietBeer> so i guess i should use async sockets to do the portscan?
[9:47] <SovietBeer> and run the futures on a threadpool of fewer threads
[9:47] * JakeSays (~jake@63.226.106.92) Quit (Ping timeout: 248 seconds)
[9:48] <brianx> an async os call would allow fewer threads to saturate the os's ability to generate request packets and get the replies.
[9:49] <brianx> async calla
[9:50] <brianx> async calls may not be the best overall performance, you'll have to see what works in your language.
[9:54] <SovietBeer> ok, i'll try that :)
[9:55] <SovietBeer> with this: https://tokio-rs.github.io/tokio-proto/tokio_proto/struct.TcpClient.html#method.connect
[9:56] <brianx> if you want the best overall performance out of a given small cpu like a pi, dump the high level language like rust and stick to low level like C where you as the programmer get to choose what features you need instead of all the crud rust guarantees. all those generic guarantees cost overhead.

[9:59] <brianx> nor is memory safety, nor is thread safety.
[9:59] <SovietBeer> memory safety and thread safety ARE zero cost in Rust..
[9:59] <SovietBeer> it's all checked at compile-time
[10:00] <brianx> you can believe that.
[10:01] <brianx> high level languages will never compete with well tuned lower level languages.
[10:01] <SovietBeer> brianx: can you give some proof for your claims that memory safety and thread safety are not zero cost in Rust?
[10:02] <brianx> there is never such a thing as a free lunch.
[10:02] <SovietBeer> -.-
[10:02] <SovietBeer> have you even used Rust?
[10:02] <brianx> it's up to the person making the absurd claim to offer proof.
[10:02] <brianx> no, i will not use rust. no thank you.

[10:07] <choscura> I'm googling this rust thing
[10:08] <brianx> it's just another high level language. nothing of much interest choscura.
[10:08] <choscura> "syntactically similar to c++ but with better memory management". It's C# dressed up as C++.
[10:08] <SovietBeer> even on rpi, my client uses below 1% cpu usage (after the port scan)
[10:08] <gordonDrogon> a sinle threaded port scan will be waiting on the network most of the time if its written correctly.
[10:09] <SovietBeer> choscura: it's not C#, it compiles to machine code, it's as fast as C/C++ and zero overhead
[10:09] <SovietBeer> gordonDrogon: that's why i'm using 200 threads..
[10:09] <SovietBeer> but gonna switch to async
[10:09] <choscura> maybe share your code and start there, is this on git?
[10:09] <brianx> i guess your client doesn't do much. no need to optimize if there isn't much going on. except where there is.
[10:10] <SovietBeer> choscura: no it's for my job
[10:10] <choscura> eh? are we getting paid? lol
[10:10] <SovietBeer> Rust pays well ;)
[10:11] <brianx> so they're getting paid.
[10:11] <brianx> not us.
[10:11] <choscura> eh, so do all programming languages, and for what you're describing, I'd normally expect to see someone talking about Go
[10:11] <gordonDrogon> why write a portscanner though - what's wrong with nmap these days?
[10:11] <brianx> ^^^
[10:11] <SovietBeer> choscura: btw, this is my parallel portscan code using 200 threads: http://dpaste.com/1FVRGGM
[10:12] <SovietBeer> choscura: Go is C#, it sucks
[10:12] <brianx> iirc, nmap can even send custom requests now.
[10:12] <SovietBeer> gordonDrogon: because i need the result as a value and why should i parse the output of nmap when i can just do it myself?
[10:13] <choscura> dude, get some raspberry pis and test this, it looks like

[10:13] <choscura> then, how many threads did it choke on?
[10:15] <SovietBeer> with 200 threads i get 100% cpu usage but the scanning still takes too long, even if the subnet only contains 254 addrs, so i'm going to switch to async
[10:15] * orti (~orti@p54A627CB.dip0.t-ipconnect.de) has joined #raspberrypi
[10:16] <gordonDrogon> why not analyse the system and work out where the bottleneck is?
[10:16] <choscura> then run a profiler, see how many threads you can spawn before it chokes out.
[10:16] <gordonDrogon> have you saturated the network or the kenel scheduler?
[10:16] <choscura> that's at network level
[10:16] <SovietBeer> choscura, brianx: btw, Rust is first in the TechEmpower server benchmark: https://www.techempower.com/benchmarks/#section=data-r16&hw=ph&test=plaintext
[10:16] <SovietBeer> and 2nd and 3rd in json https://www.techempower.com/benchmarks/#section=test&runid=6bb9ecf9-5be0-4cb4-b52b-16ea1a3b105b&hw=ph&test=json
[10:17] <SovietBeer> before Go etc
[10:17] <brianx> port scanning is an odd way to find industrial machines on a lan anyway. if you're looking for one specific type machine, it should be using a mac from a specific manufacturer and listening on a specific port. querying the switch or router to see the list of active ip addresses should reduce the candidates to a few and hitting the listening port on them is only a few requests.
[10:17] * kuzeyron (~amadeusxn@host-121-25.parnet.fi) has joined #raspberrypi
[10:18] <SovietBeer> brianx: yes, they are all listening on port 1010. what's the best way to query the switch/router for active IPs though?
[10:19] <brianx> SovietBeer: first of the lousy is not saying much.

[10:19] <choscura> also go is #2 in the first example
[10:19] <choscura> I think it's down at like #14 out of 260 or whatever in the second
[10:20] <choscura> and, SovietBeer, arp-scan
[10:20] <brianx> the router query is vendor specific. most have some sort of show arp command or list known mac addresses command.
[10:20] * orti (~orti@p54A627CB.dip0.t-ipconnect.de) Quit (Ping timeout: 256 seconds)
[10:21] <SovietBeer> brianx: it has to work router-agnostically..
[10:21] <brianx> arp-scan is again active. the switch and router know.
[10:21] <choscura> hang on
[10:21] <brianx> agnostic isn't going to work.
[10:21] <SovietBeer> how many different vendor queries are there?
[10:22] <brianx> how many vendors are there?
[10:22] <choscura> here's a good example of somebody doing something like this: https://makezine.com/projects/build-raspberry-pi-network-scanner/
[10:22] <SovietBeer> thanks :)
[10:23] <brianx> if the pi has been up awhile it also will know what mac addresses it has seen recently.
[10:23] <SovietBeer> so this tool is basically doing all the vendor-specific stuff? https://github.com/royhills/arp-scan
[10:23] <choscura> also on that front, most reliable way to run a pi I've found is to have it plugged into an externally powered USB device, eg hub.
[10:23] <SovietBeer> not as easy to replicate as a portscanner?
[10:24] <choscura> so, you have 2 power supplies, in case that isn't clear.
[10:24] <choscura> SovietBeer, yes, arp-scan is a mature thing that's been around a few years now
[10:24] <SovietBeer> brianx: but the pi won't have seen the industrial devices' mac unless it communicated with them since boot, right? (and it won't do that without my client doing it)
[10:24] <choscura> like, since the 90's at least, iirc, lol
[10:25] <SovietBeer> choscura: do i have to parse its text output or can i use it as a lib?
[10:25] <choscura> I'm not sure on the lib, actually, but I'd be surprised if there's not a handler for that somewhere.
[10:25] <brianx> a broadcast arp is replied to by some systems, see if your target responds to one. if you're lucky, it will and all you have to do is send one packet, then look through the replies for mac with the correct first 6 nibbles.
[10:26] <choscura> also wireshark ftw
[10:26] <choscura> since that just makes the 'looking for nibbles' job easier
[10:26] <SovietBeer> yes, with arp-scan it shows the device
[10:27] <SovietBeer> choscura: wireshark is quite heavy though..
[10:27] <SovietBeer> as a dependency
[10:27] <brianx> SovietBeer: the pi will hear any arp broadcast. some devices reply with a directed response and that won't be seen. but knowing your target's behavior will tell you more about what you can use.
[10:27] <choscura> I wasn't suggesting wireshark as a dependency, but as a diagnostic
[10:28] * drzacek (~drzacek@b941c009.business.dg-w.de) Quit (Ping timeout: 256 seconds)
[10:31] <brianx> i'd start with a broadcast arp and see if your target device will reply.
[10:31] <SovietBeer> brianx: ok thanks. so i need wireshark to find out if my device's arp reply is directed only towards the router or broadcasted?
[10:31] <brianx> wireshark is one tool to figure that out.
[10:32] <SovietBeer> brianx: by "broadcast arp" do you mean using the arp-scan tool? (like `sudo arp-scan --retry=8 --ignoredups -I wlan0 --localnet
[10:32] <SovietBeer> `)
[10:32] <brianx> no, not arp scan.
[10:32] <brianx> a broadcast arp is a single packet.
[10:32] <SovietBeer> so i should send that from my client to the broadcast ip?
[10:33] <brianx> nope.
[10:33] <brianx> it's a specific packet.
[10:33] <brianx> called a broadcast arp.
[10:34] <SovietBeer> ok
[10:34] <brianx> if you're lucky, your target machine will respond to one.
[10:35] <brianx> SovietBeer: you just showed wlan0 in your example. this is not a lan device name.
[10:35] <SovietBeer> is arp broadcast the same as ARP Gratuitous Request ?
[10:35] <SovietBeer> brianx: yea i used the ethernet iface in my invocation
[10:36] <brianx> ok, because things are different on wifi.
[10:37] <brianx> i forget if the gratuitous arp is the same thing or not.
[10:37] <SovietBeer> maybe i can reuse this: https://github.com/Dineshs91/send-arp#send-gratuitous-arp-request
[10:37] <SovietBeer> http://blog.dineshs91.com/post/send_arp/
[10:38] <brianx> gratuitous arp is not the same as a broadcast arp.
[10:38] <SovietBeer> ah
[10:40] <SovietBeer> this seems suitable https://github.com/gavynriebau/arp-scanner
[10:40] <brianx> broadcast arp request that is.
[10:40] <SovietBeer> "Works by firing ARP requests for each possible address and listening for ARP replies."
[10:40] <SovietBeer> but broadcast arp would only require 1 request, right?
[10:40] <SovietBeer> so this isn't perfect?
[10:40] <brianx> again, scanning is not the same.
[10:41] <brianx> yes, a broadcast arp request packet is one packet that many devices will respond to.
[10:41] * High_Priest (~hp@unaffiliated/high-priest/x-8117523) Quit (Quit: Leaving)
[10:41] <SovietBeer> so that's what the arp-scan tool sends, too?
[10:41] <brianx> your particular target may or may not.
[10:42] <brianx> no, arp-scan sends out a query to every possible ip.
[10:43] * yvi (~yvi@unaffiliated/yviwp) Quit (Quit: Quit)
[10:43] <brianx> read up on arp and the various things different systems do. knowing the os on your target may tell you how it will react or how it can be found.
[10:45] <brianx> the router or switch is usually the easiest way to find a list of mac addresses, but if you don't use a specific brand then you'll have trouble getting that.

[10:47] <brianx> the old arp-scan is just that, a scanner. it sends one packet to every possible ip on the defined subnet. if that's a class c, it's not tooooo bad, but if you hit a class b network then you'll be waiting awhile.

[10:55] <brianx> there are too many for me to type. most involve reacting to some sort of broadcast or doing some sort of broadcast often.
[10:55] <brianx> rtfm.
[10:55] <SovietBeer> which tool would you recommend to check if it responds to broadcast arp? or is there no tool for that?

[11:00] <brianx> none of this makes any sense. the administrator who set this thing up knows the ip. if you have permission to use it, the admin will tell you it's ip address.

[11:02] <lastaid> good day. i was wondering if there is any documentation on how to add a unsupported rtc modul to the raspberry pi.
[11:03] <brianx> either ncat or scat should be able to send the broadcast arp packet. i've not needed to use it in decades so i don't have a tool handy.
[11:03] <SovietBeer> in most cases it should be a class c network
[11:03] <brianx> s/scat/socat/
[11:04] <brianx> c can also craft the packet. :-p
[11:04] <BurtyB> or a /24 unless you're still living in the 90s
[11:05] <SovietBeer> brianx: with rust, too: https://docs.rs/rips-packets/0.1.0/rips_packets/arp/struct.ArpPacket.html
[11:05] <brianx> i don't and won't rust.
[11:06] <SovietBeer> i'm not saying you have to ;)
[11:06] <SovietBeer> i'm just saying i'm using rust..
[11:06] <brianx> ok
[11:07] <SovietBeer> but i'm not familiar enough with the arp protocol to know how to do it manually yet..
[11:07] <SovietBeer> i'd also have to listen to the reply packets..
[11:07] <brianx> no, you don't. your os listens and puts them in the arp table, then you read the arp table.

[13:39] <laris> thanks both for help he was pleased with date -s for now without having ntp synchronized. I told him most of the above, to use raspi-config but said to him to use /etc/init.d/ntp for restart. It's fine till next power surge I guess :P. the pi is used for alarms all day long so having the time set is a must.

[15:12] <tvm> same TV, same cables, same PSU, everything is damn same except the boards
[15:12] <tvm> and this happened suddenly today

[15:24] <tvm> i used one 3B+ for regular testing, after i encountered this, i took the reserve one from box and same result

[15:38] <lopta> That's possible.
[15:38] <tvm> trying new one
[15:38] <tvm> but why it would work on 3B and not on 3B+ ?
[15:39] <mfa298> it might be worth checking that file in case the images got mixed up somehow (it's a decent double check).

[19:42] <Habbie> Voop, the code? the tickets? the wiki?
[19:43] <uriah> Voop: does the repository still exist? you can clone the repository at the commit before whatever was removed
[19:44] <uriah> side note: I’m working on a tiny live gentoo environment for rpi3 some of you may be curious about
[19:44] <Voop> Habbie: the code i guess
[19:44] <Habbie> Voop, git clone
[19:45] <Habbie> Voop, also the 'fork' button on github
[19:45] <Voop> i thought that that installed it on my system
[19:45] <Voop> does it just copy it
[19:45] <Habbie> git clone only downloads things
[19:45] <Voop> ok cool
[19:45] <Voop> where does it put it
[19:45] <uriah> 64bit, using musl-libc and busybox, includes mpv and firefox on wayland
[19:45] <Habbie> Voop, in a new directory inside your current directory
[19:46] <Habbie> uriah, why musl and busybox?
[19:46] <Voop> so id have to cd to the directory i want to put it in
[19:46] <uriah> except right now I’m stuck on a bus error when running Firefox
[19:46] <Habbie> Voop, always best
[19:46] <uriah> Habbie: because I wanted to see how small an image I could fit all of that in
[19:47] <Habbie> uriah, i somehow doubt those two make a lot of difference once firefox is in
[19:47] <uriah> I’m loading the whole thing to memory so I can swap the sd card
[19:47] <Habbie> right

[19:47] <uriah> it’s under 130MB
[19:47] <uriah> including kernel
[19:47] <uriah> lol
[19:47] <Habbie> uriah, and how big would it be with glibc and 'not busybox'?
[19:48] <uriah> probably ~200-300MB
[19:48] <Habbie> oh wow
[19:48] * turtlehat (~ouaei@5CEC365.rev.sefiber.dk) has joined #raspberrypi
[19:48] <Habbie> 130MB including kernel, no modules i suppose?
[19:48] <uriah> all the modules
[19:49] <uriah> I disabled some stuff i didn’t need because the rpi provided defconfig is pretty bloated
[19:49] <Habbie> right
[19:49] <Habbie> so why do you want to remove the sd card?
[19:50] <uriah> but yeah it’s a pretty neat project
[19:50] <Khaytsus> Shame the pi can't pxe boot
[19:50] <Habbie> Khaytsus, you mean like the pi2 and every model after it in fact can?
[19:50] <uriah> Habbie: well don’t you think it’s silly not to be able to use more than one sd card at once?
[19:51] <uriah> like

[19:51] <Khaytsus> Habbie: oops, I'm confused then. I'd always heard Pi's couldn't PXE boot. Old info apparently.
[19:51] <uriah> if one gets full
[19:51] <Habbie> uriah, not that i think that that was in fact what i was asking, but usb sd readers are cheap
[19:51] <davr0s> PXE boot = ?
[19:51] <Khaytsus> uriah: That's a nonsense problem.
[19:51] <Habbie> Khaytsus, indeed!
[19:51] * kingarmadillo (~kingarmad@38.104.254.34) has joined #raspberrypi
[19:51] <uriah> true
[19:51] <uriah> but anyway
[19:51] <uriah> runs pretty fast too
[19:51] <Habbie> sure
[19:52] <Habbie> but
[19:52] <Habbie> firefox crashes on startup?
[19:52] <uriah> and this reduced io
[19:53] <uriah> Habbie: well yeah it’s using tons of experimental patches for aarch64, musl and wayland support
[19:53] <uriah> still buggy
[19:53] <Habbie> yeah
[19:53] <Habbie> so step one
[19:53] <Habbie> use a functional libc
[19:53] <uriah> lol
[19:53] <uriah> musl is quite functional
[19:53] <Habbie> before you try to do things with a dysfunctional libc
[19:53] <Habbie> well let's not get into that
[19:53] <uriah> ok
[19:53] <Habbie> we can reverse this
[19:53] <uriah> anyway
[19:53] <Habbie> 'i bet firefox makes a lot of assumptions that hold true for glibc'
[19:54] <Habbie> so i'd still start there
[19:54] <Habbie> until things work
[19:54] <uriah> yeah
[19:54] <uriah> I should probably look at the aarch64 and wayland patches to see if glibcisms are in there
[19:54] <uriah> anyway
[19:55] <uriah> once/if it works... pretty sure you’ll like it :>
[19:55] <Habbie> maybe :)

[23:21] <choscura> Hdale85, get your SSH keys set up
[23:21] <choscura> hang on, I'll point you to a link
[23:21] <Hdale85> yeah
[23:21] <Hdale85> I had to start with a clean image
[23:22] <Hdale85> I guess the hard restart messed something up
[23:22] <choscura> https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/
[23:23] <choscura> that lets you click the "download" option button and basically copy the URL and go "git clone X" in your terminal, where X is the repository root HTML

[23:31] <katnip> i have a pi 3 or 2, some time back, we had two nights of storms. our power went out and since then, our pi wont load an OS (raspbian). do you think the SD card is blown or the pi is blown. which do you think.?
[23:33] <linyos> if you have lights flashing on the pi, it's probably a corrupted sd card
[23:34] <linyos> you power supply would be affected before the pi i would imagine

[23:46] <Hdale85> been ages since I've tinkered with this kind of stuff and I didn't write this code so I have no idea what a lot of that means lol
[23:48] <Voop> that looks to be a python script
[23:49] <Hdale85> it's not a script, it's a bunch of output from trying to run a script lol
[23:50] <Hdale85> mainly the part about the HTTP server
