[0:00] * venmx (~pactadmin@host31-48-148-246.range31-48.btcentralplus.com) Quit (Ping timeout: 256 seconds)
[0:03] <wp> [Saint], the reason for C++ is to relearn it for my new job which starts in a month
[0:04] <[Saint]> I think that was intended for someone else.
[0:04] <[Saint]> mfa298: seems like that was for you.
[0:04] * razzy (~user@unaffiliated/razzy) has joined #raspberrypi
[0:04] <wp> so i did a bunch of small programs to learn templates classes etc. now i jsut want to put it all together in a bit bigger program and learn a little more about the rpi in the process
[0:04] * venmx (~pactadmin@host31-48-148-246.range31-48.btcentralplus.com) has joined #raspberrypi
[0:05] <[Saint]> wp: I asked 'why opencv', not 'why c++', FWIW.
[0:05] <wp> [Saint], just for fun, image analysis is cool. if i use something ready made there is no code to write :(
[0:05] <[Saint]> My personal opinion is that ffmped/avconv is probably going to be more useful to you, and your application is likely to be making use of it anyway.
[0:05] <[Saint]> wp: opencv is something ready made...
[0:06] <wp> right now i am just looking at the alternatives really, havent decided
[0:06] * clemens3 (~clemens@178-82-161-195.dynamic.hispeed.ch) has joined #raspberrypi
[0:07] * genericuser123 (~enter@43.225.32.90) has joined #raspberrypi
[0:07] <[Saint]> I'm just saying your application is almost certainly going to be using ffmpeg to encode, transcode and/or stitch frames or containers, so in my mind it makes sense to use it for difference comparison as well.
[0:07] * GerhardSchr (~GerhardSc@unaffiliated/gerhardschr) Quit (Quit: Leaving)
[0:07] * GerhardSchr (~GerhardSc@unaffiliated/gerhardschr) has joined #raspberrypi
[0:07] <[Saint]> Unless you want to do more than "difference comparison with threshold" and actually do want to do distinct object recognition.
[0:08] * nicedreams (~nicedream@138.68.41.211) Quit (Quit: ZNC 1.6.5+deb1 - http://znc.in)
[0:08] * GerhardSchr (~GerhardSc@unaffiliated/gerhardschr) Quit (Client Quit)
[0:08] <[Saint]> If you just want to know if the current frame is statistically significantly different from the last N frame(s) and use the to trigger capture, ffmpeg seems like the perfect fit.
[0:09] * swift110_ (~swift110@unaffiliated/swift110) has joined #raspberrypi
[0:10] * swift110 (~swift110@unaffiliated/swift110) Quit (Ping timeout: 256 seconds)
[0:10] <[Saint]> I /probably/ don't need to say it, but your biggest hurdle to speed and efficiency is IO.
[0:10] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 265 seconds)
[0:10] <[Saint]> Do your comparison captures and work in a RAMdisk if at all possible and extract from there with a deferred process as required.
[0:10] * m_t (~m_t@p5DDA2B1D.dip0.t-ipconnect.de) Quit (Quit: Leaving)
[0:10] <mfa298> wp: if you're job requires c++ then that seems like a fair reason (although getting a job for which you don;t have the skills seems a bit odd), however the sign of a good coder is that they look at the available libraries and use them where appropriate rather than re-inventing the wheel.
[0:11] * wp (~wp@ua-84-219-215-81.cust.bredbandsbolaget.se) Quit (Quit: Leaving)
[0:11] <[Saint]> mfa298: right, that's why I asked if there was a specific requirement for opencv, as it seems like a weird fit just for difference comparison.
[0:12] <[Saint]> Now, if you're wanting to do difference comparison and train object recognition...then things get different, and it's the obvious choice.
[0:13] * Win7ine (~Win7ine@cpc142190-mort7-2-0-cust7.19-2.cable.virginm.net) Quit ()
[0:13] * shantorn (~shantorn@184-100-234-79.ptld.qwest.net) has joined #raspberrypi
[0:14] <mfa298> I wonder if image matching is the best of projects if the aim is to learn C++, there's probably better things out there. If this is learning skills for a job I'd probably start be looking for some project that's along the same lines as the company in question.
[0:16] * swift110 (~swift110@unaffiliated/swift110) has joined #raspberrypi
[0:17] * clemens3 (~clemens@178-82-161-195.dynamic.hispeed.ch) Quit (Ping timeout: 260 seconds)
[0:18] * clemens3 (~clemens@80-218-38-71.dclient.hispeed.ch) has joined #raspberrypi
[0:19] * mmazing (~mmazing@unaffiliated/mmazing) Quit (Quit: Leaving)
[0:20] <[Saint]> mfa298: I was wondering that myself, but I think it's more just a personal thing and this person is wanting to shape their skills in C++ with a project that interests them personally.
[0:21] <[Saint]> That's why I tried to ask whether or not that personal interest extended to opencv specifically or not.
[0:21] * en1gma (~en1gma@176-80-181-166.mobile.uscc.net) Quit (Quit: Leaving)
[0:21] <[Saint]> Because to me using opencv for this seems kinda like buttering your toast with a katana.
[0:22] <stiv> you don't need the *best* project, you need *a* project for the practice using the language. any image matching and analysis will be done via a library like opencv
[0:22] <[Saint]> I mean, sure, you can do it...and it's a knife, but, a butter knife would work just as well.
[0:23] * andreas303 (~andreas30@h-70-56.A163.priv.bahnhof.se) Quit (Quit: leaving)
[0:23] * andreas303 (~andreas30@h-70-56.A163.priv.bahnhof.se) has joined #raspberrypi
[0:23] <[Saint]> stiv: well, surely the end result is also intended to produce an efficient and workable product as well?
[0:24] <[Saint]> Otherwise you may as well just work through Euler math, or go nuts with fizzbuzz.
[0:24] <mfa298> its a long time since I looked at any image matching stuff (and that probably predated opencv and maybe even ffmpeg) so I cant comment on that aspect.
[0:25] * defsdoor (~andy@cpc120600-sutt6-2-0-cust177.19-1.cable.virginm.net) Quit (Remote host closed the connection)
[0:25] <[Saint]> I mean, in all seriousness, if you're just wanting to hone your skills with a language it probabbly *is* better to just work through a math problem set.
[0:25] <[Saint]> But if you actually want to make a product at the end of it all, I don't see any reason why you shouldn't make steps to providing the best fit for that end result.
[0:26] * akk (~akkana@75-161-91-17.albq.qwest.net) Quit (Ping timeout: 264 seconds)
[0:26] <[Saint]> Learning that behaviour is probably going to be more useful to you in the long run.
[0:26] * shantorn (~shantorn@184-100-234-79.ptld.qwest.net) Quit (Quit: Leaving)
[0:28] <mfa298> in some respects, finding a project that uses a good library (or even a few) might be a good one to go for to get experience of reading library documentation.
[0:28] <[Saint]> Yes. That's fair.
[0:29] <mfa298> the quality of documentation for some libraries (particularly in the C and C++ worlds) can vary quite a bit, and it can also show where you knowledge is lacking
[0:29] <[Saint]> ffmpeg's documentation, both internal and external, is pretty bloody amazing.
[0:30] <[Saint]> in all fairness opencv's is far from terrible, too.
[0:30] <[Saint]> I find it personally more difficult to navigate, but they're both extremely robust and complete.
[0:31] <mfa298> I'd expect ffmpeg to be pretty decent. I was thinking of some of the others I've looked at in the past. Sometiems it's just a case of gettign in the authors head to work out how to read the stuff. The detail is often there, just hard to find the bits you want sometimes.
[0:32] <[Saint]> Yes.

[0:36] * blahdodo (~blahdodo@69.172.190.157) Quit (Quit: Bye bye)
[0:37] <[Saint]> ffmpeg is really one of those shining examples of documentation done right.
[0:37] <[Saint]> doxygen generation refined by humans after the fact.

[0:54] <puff> GOod evening.
[0:54] <puff> I'm putting together a pi zero w with a camera. The pi zero w came with an extra camera ribbon that's shorter, I'm trying to insert that into the camera but it feels like it's not really inserted. I don't want to push too hard and break the camera. Is there a trick to this?
[0:55] <puff> ah, I think I got it.

[0:59] <puff> Hm, it the pi zero case came with three different lid styles. It *looks* like one of them is designed to have the camera board inside the case, with the a hole in the lid for the camera lense.

[4:24] <fogus> Right now, I get nothing from doing a `cat /dev/serial0` or /dev/ttyAMA0
[4:25] <fogus> A new line prints and then it just sits there
[4:25] <fogus> I tried the python code from http://www.instructables.com/id/Read-and-write-from-serial-port-with-Raspberry-Pi/
[4:25] <fogus> I just get blank lines

[6:45] <nickgaw> Hi, I am totally blind and have the light jessie image running on my raspberrypi 3b which is connected to my wireless network and was wondering what the current name of the rasbian release is and if it is safe to just change the release information and remove the old headers and just do sudo apt-get update then dist-upgrade to upgrade the operating system? I don't have X windows on my image.

[11:34] * v01d4lph4 (~silent_fr@103.201.141.10) Quit (Remote host closed the connection)
[11:34] <ShorTie> sounds like it needs a systemd upgrade
[11:35] <ShorTie> or switch your system back to sysvinit
[11:36] * kihis (uid4787@gateway/web/irccloud.com/x-gezzmynwlxgrdbme) has joined #raspberrypi
[11:37] <tomeaton17> ShorTie: Ah, is that systemv style? Yeah I should probably upgrade to systemd
[11:38] <ShorTie> nothing wrong with still using sysvinit
[11:38] <ShorTie> you have been upgrade to systemd, that is the problem
[11:39] <tomeaton17> ShorTie: Yeah this code was worked on many years ago. For future proofing would it be recommended to change to systemd?
[11:40] * waveform (~waveform@waveform.plus.com) has joined #raspberrypi
[11:41] <ShorTie> if you can switch the init scripts over to systemd, might be a good idea
[11:41] * BurtyB would do both so when the world realises how bad systemd really is, you have it ready ;)
[11:43] <Tykling> yeah that isn't happening
[11:43] <ShorTie> i'm workin on a cdebootstrap script, it cdebootstrap the 3rd partition, then rsync it to the 2nd and switches the 2nd back to sysvinit
[11:43] <ShorTie> so i got both, hehe.
[11:43] <tomeaton17> Well I already have systemv scripts, but will need to make the systemd ones. Everything seems to be switching from upstart anyway so might aswell. Time to learn systemd
[11:44] <ShorTie> once done, stick them up on github for all
[11:45] <tomeaton17> No can do unfortunately, this is stuff for my internship

[13:04] <daveylib> Hey guys! Have you ever recompiled kernel for RaspberryPi 3?
[13:04] <darsie> no
[13:04] <Habbie> i'm sure some people have
[13:04] <Habbie> why?
[13:04] <daveylib> I use this official tutorial https://www.raspberrypi.org/documentation/linux/kernel/building.md
[13:05] <daveylib> But after recompiling when I type "sudo make modules_install" I get a lot of errors.
[13:05] <Habbie> what are the errors?
[13:05] <daveylib> "No such file or directory"
[13:06] <daveylib> After that command I need to copy files (the last part of the tutorial), but there are no files.
[13:06] <lembron> there is another word infront of what you just copypasted, and thats more intresting

[16:47] <gordonDrogon> oops. ignore that.
[16:47] <_matix> gordonDrogon yeah I need pullup on the pin and my understanding was that the I2C pins have pullup resistors builtin
[16:47] <_matix> (still struggling with my DHT12..)
[16:48] <_matix> I just checked `gpio readall`, it is indeed the correct pin number
[16:48] <gordonDrogon> yes, that pin has an on-board 1k8 pullup.
[16:48] <gordonDrogon> also make sure you do not have the I2C drivers loaded - use raspi-config
[16:49] <_matix> gordonDrogon
[16:49] * philomath_ (~da_vinci@112.196.147.152) has joined #raspberrypi
[16:49] <_matix> i'm now checking with GPIO17 wired to GND

[16:49] <_matix> "gpio -g read 17"
[16:49] <_matix> i've soldered power to ground somewhere haven't i
[16:49] <gordonDrogon> ok. disconnect everything if you can.
[16:50] <gordonDrogon> and type this: gpio -g mode 17 in ; gpio -g mode 17 up ; gpio -g read 17
[16:50] <gordonDrogon> and tell me what you get.
[16:50] <_matix> 1
[16:50] <gordonDrogon> ok, that's good.
[16:50] <gordonDrogon> no type this: gpio -g mode 17 down ; gpio -g read 17
[16:50] <gordonDrogon> and let me know what you get.
[16:50] <_matix> 0
[16:50] <gordonDrogon> ok, so the pin is working fine.
[16:51] <gordonDrogon> I think you may be connecting to the wrong pin.
[16:51] <_matix> ok
[16:51] * taza (~taza@unaffiliated/taza) has joined #raspberrypi
[16:51] <gordonDrogon> the up/down commands set the internal pull-up/pull-down resistor.
[16:51] <_matix> so if i need pull-up, i should just use pullup mode on the pin instead of using the I2C pins
[16:51] <gordonDrogon> set it back to up then try your wire to 0v again.
[16:51] <gordonDrogon> you can use either.
[16:51] <_matix> ok i have 17 to GND
[16:52] <_matix> will try both commands
[16:52] <gordonDrogon> no, only gpio -g read 17
[16:52] <_matix> 0
[16:52] <_matix> so everything is fine
[16:52] <gordonDrogon> maybe.
[16:52] <gordonDrogon> you need to set the internal pull-up, then remove the wire.
[16:52] <gordonDrogon> and make sure it reads 1
[16:52] <_matix> ok
[16:53] <_matix> so gpio -g mode 17 up
[16:53] <_matix> then remove
[16:53] <gordonDrogon> yes
[16:53] <_matix> then gpio -g read 17
[16:53] <_matix> yeah it's a 1
[16:53] <gordonDrogon> ok, type this:
[16:53] <gordonDrogon> while true; do gpio -g read 17 ; done
[16:53] <gordonDrogon> that'll print the readings constantly.
[16:54] <gordonDrogon> then you can test the wire on/off.
[16:54] <gordonDrogon> hit Ctrl-C to exit.
[16:54] <_matix> it doesn't change when i put it to ground
[16:54] <_matix> and now if i do gpio -g read 17 it's reading a 1
[16:55] <_matix> (despite being plugged to GND)

[17:03] <_matix> but the grounds on the pi are all on the same bus right?
[17:03] <gordonDrogon> yes they are.
[17:04] <_matix> ok
[17:04] <_matix> so i've just not soldered that pin properly
[17:04] <gordonDrogon> does the solder joint look shiny or sort of dull?
[17:05] <_matix> a little dull
[17:05] <_matix> this ground is particularly bad
[17:05] <gordonDrogon> it may be what's called a "dry joint".

[17:58] <en1gma> now i dont know if any of the apps are actually for armv8 or not. how can i tell?
[17:59] <shiftplusone> in 99% of cases, the architecture isn't the issue. I'd focus on figuring out what's slow and why, then you'll know whether anything can be done about it. Usually the issue is that software developers work on i7s and desktop graphics cards and don't worry about performance until it's too late.

[18:01] <shiftplusone> Again, you won't get any performance improvements by compiling for armv8. If you want to try anyway, the current version of gcc can be used, you just need to pass the right flags.
[18:01] * Dave_MMP is now known as djsxxx_away
[18:03] <shiftplusone> The only noticeable improvements you'd get would be from NEON and possibly some crypto instructions, but very few applications use those. The ones which do are already using NEON in Raspbian (with a few exceptions).
[18:03] <en1gma> so using an armv6 app (precompiled binary) vs an armv8 built fresh wont make a difference with performance?

[18:04] <shiftplusone> You'll see some difference in some benchmarks. Some operations are a little faster, some are a little slower. In the end, the user won't notice any difference.
[18:04] <en1gma> in gqrx i believe it uses the gpu for FFT. the armv6 version uses the older pi hardware dont it?
[18:05] <shiftplusone> All pis have the same GPU, the issue is probably that they're doing FFT in software rather than trying to use the GPU.
[18:05] <en1gma> it sure feels like it

[18:11] <en1gma> well might have saved some time from downloading and installing another distro and having same problem
[18:11] <gordonDrogon> anairo, are you running Raspbian? If not, then switch to Raspbian ...
[18:11] <shiftplusone> en1gma: do you know what fft library the software is using?
[18:11] <anairo> gordonDrogon: Why switch?
[18:11] <en1gma> i did have the raspbian light image and later installed lightdm. the desktop actually feels fast and light :)

[18:13] <gordonDrogon> anairo, because it's more popular and comes with a lighterweight gui than mate.
[18:13] <en1gma> shiftplusone i "assume" its using the librtlsdr library and inside that there is rtl_power but someone else had made rtl-sdr with modified rtl_power_fftw which is way more optimized for pi3 to my understanding. i believe gqrx is using the original rtlsdr rtl_power
[18:13] <en1gma> not sure though
[18:13] <anairo> gordonDrogon: Ok. What am I going to lose when switching to raspbian?
[18:13] <shiftplusone> FFT is an area where NEON can make all the difference.
[18:13] <gordonDrogon> anairo, no idea - I don't know what you have.

[18:15] <gordonDrogon> anairo, but if your current distro is debian based then why not simple apt-get install whatever desketop/gui you want..
[18:15] <shiftplusone> if it's using some generic fft library, there's a chance I could make it work a lot nicer in Raspbian.
[18:16] <en1gma> i know quite a few ppl would appreciate that. ##rtlsdr ppl use pi3 and beaglebone black for some of their projects
[18:16] <anairo> gordonDrogon: Let me try to rephrase. If DE left out, what am I going to lose when switching? Is there a big difference?

[18:17] <gordonDrogon> anairo, I really do not know because I do not know what you currently have/do.
[18:17] <en1gma> shiftplusone checking it
[18:18] <anairo> gordonDrogon: Ok. I see. Actually you just might have told me what I wanted to know, that apt-get install is an option.
[18:18] <shiftplusone> en1gma: the developer could be a lot more clever and release a version that does FFT a lot faster.
[18:18] <anairo> gordonDrogon: Then I just need to kow the names of the packages, I guess.
[18:18] <gordonDrogon> anairo, I run xfce4 under Raspbian if that helps.
[18:19] <en1gma> that rx_fft ive been reading off and on about it. didnt think anyone was using it for a gui app yet
[18:19] <gordonDrogon> anairo, It may also be possible that whatever it is you're running (I still don't know, guessing ubuntu?) doesn't have any other desktop environment compiled in. Who knows.
[18:19] <Habbie> if it's ubuntu, there should be plenty of choice
[18:19] <Habbie> like xfce
[18:19] <anairo> gordonDrogon: Ok. I'll remember that. The thing is that I'm asking this for a friend, who doesn't want to IRC. I have no idea what he has.

[18:22] <anairo> Habbie and gordonDrogon: Thank you! You helped a lot.
[18:23] <gordonDrogon> not sure I have - probably left more questions to be asked ...
[18:23] <gordonDrogon> however 2 solutions: 1)install Raspbian, 2) look for other desktops packages & install via apt.
[18:23] <Habbie> that's the two we gave i suppose, yes :)
[18:24] <gordonDrogon> Raspbian has a custmised and optimised desktop based on .. um, fogotten. bother.

[18:31] <shiftplusone> raspbian lite, archlinux ARM.... whatever suits your needs.
[18:32] <shiftplusone> Do you really want to faff around with that? You're not going to get better performance by just running openbox
[18:33] <anairo> shiftplusone: Does ,say, raspbian come with a DE anyway?
[18:33] <shiftplusone> raspbian comes with a DE, raspbian lite does not.

[18:35] <shiftplusone> If you're not experienced, try just Raspbian. If you don't like the default lxde-based desktop, give xfce a go.
[18:36] <Syliss> xfce is awesome
[18:36] <shiftplusone> xfce is nice, but the default configuration for it in debian makes it a bit ugly, imho.
[18:36] <Syliss> but standard raspbian is great too if you only have ubunutu exp

[19:01] <shiftplusone> the good thing about linux distros is that it's fairly resistant to that kind of nonsense. gnome was doing strange things, so we got cinnamon and mate. gtk3 is doing strange things, so people still use gtk2 or switch to qt. I suspect gtk2 will be forked at some point.

[19:35] <gordonDrogon> but different people have different ideas. I worked with someone who had emacs as his shell once - rather than use X - however this was on a 4MB Sun3 which was somewhat challenged anyway - I guess I'm not much different - X is just a tool that lets me launch terminals for the most part - sometimes gimp/inkskape/xchat/webby stuff.
[19:36] <akk> Same for me, hence not needing a lot in the way of menus or panels.
[19:38] <akk> I have menu items for xterm, emacs, browser, hexchat, gimp, plus a few programs I run occasionally like arduino, fritzing, libre office (ugh).

[22:06] <mfa298> nickgaw: I'm not sure there's any generally safe overclock for the Pi3, I'm not sure how much benefit overclocking will give seeing as the cpu will get throttled as the temerature rises
[22:06] <shiftplusone> One of the ways that the pi3 has a higher clock rate than previous models is because the manufacturing process improves over time and you can get away with bumping the frequency, but it leaves less headroom to go further.

[22:06] <GrandPa-G> I have a 7 in 800x480 screen attached and configured correctly (I think). When I view an image in a program it is very pixelated and much of the color is gone. However if I use scrot and take a snapshot, it looks like what I want. Is there anything I can do or is this just a problem of resoultion limits of screen?
[22:06] <shiftplusone> So the reason raspi-config doesn't have the overclock option for pi 3 is because it in effect is already overclocked.
[22:07] <shiftplusone> You can go further, but there's no preset known safe value we'd recommend like we do for the other models
