Just starting

Had to hand out another 15 laptops today. Deployed my DefaultPrinterChanger app

FML Cat

Hmm. Ironically the only light emitting thing in my living room that can't have it's colour temperature adjusted from my phone is my computer screen

Though Windows 10 does now have a "night mode" colour temperature control it's neither close nor synchronises with my lighting

So while @JourneymanGeek is building bias lighting to make the background light in his room blend to his computer screen, I need to do the opposite... build something that'll make my computer screen lighting blend to the rest of the room :-P

Canadian Luke

The Windows 10 night-mode lighting made me think I needed to replace my monitor

Finally found the option, then I got my whites back

FML Cat

Canadian Luke

Exactly! Makes a big difference!

FML Cat

@CanadianLuke Lol it turns itself off during the day by default

Canadian Luke

03:27

But when I bring my laptop home at night after work....

FML Cat

But sadly it doesn't even come close to matching the colour range of my room lighting, nor have I figured out how to set it differently for different monitors that have clearly differing colour response

Ave

@FMLCat why is everything red?

FML Cat

Funny enough the only way to get the two monitors close is to set the slider all the way to the left, which makes everything super red

Hilariously the mouse cursor isn't affected so is still daylight white

bwDraco

@FMLCat Same here. That's one of the first things I noticed with night light on Windows 10.

FWIW my displays are color-calibrated with a colorimeter.

FML Cat

@Ave Cause I wasn't in the mood for blue

Ave

03:31

@FMLCat makes sense.

FML Cat

Ermm, yeah, I really need some way to synchronize screen colour temp with room lighting...

Yet another one of those areas where Android has overtaken desktop/Windows

My phone has a built-in RGB ambient light sensor so in addition to adjusting screen brightness it now subtly adjusts colour tone as well

In fact, even being able to adjust screen brightness from the desktop would be nice... something laptops do fine but desktop monitors desperately lack some sort of standard for this basic functionality!

My old HP professional workstation displays had some proprietary HP software that let me adjust the monitor settings from the desktop... Interface was cumbersome but it did allow scripting so I could always fudge it myself

bwDraco

Speaking of lighting... got suggestions for RGB light strips I can easily attach to the inside of the case? I'm looking into adding more RGB to the system.

Not fixed color. I need to be able to set it to #e010ff.

Lights do not need to be individually addressable.

@FMLCat I might have an idea. Lemme get back to you

bwDraco

The strip will be placed along the top of the chassis – magnetic attachment is a plus.

My biggest complaint with Astaroth's aesthetics is the lack of illumination inside the case. While the motherboard and graphics card have RGB lighting, a lot of people have the whole system lit from within, not just specific parts. As things stand, the lighting just doesn't do $4,000's worth of hardware justice.

@Bob Started with RCX, then NXT, then EV3

Bob

then uni was using the NXT with custom firmware

@Bob ev3 actually runs linux!

Bob

@rahuldottech EV3's too new for me :P

rahuldottech

It's so much more advanced than NXT, I love it

allquixotic

10:38

@Bob oh god, I used RCX in university one time

Bob

@allquixotic funnily enough I think my first RCX encounter was during a school trip to a uni

allquixotic

we wanted to do something that the Fisher-Price building blocks klickibunti software wouldn't let us do, but we needed more time than we had been allotted in the lab to do the coding in C/C++ (linking against the RCX libs) to directly control the device and read from sensors

Bob

might've even been the same uni I later did the course with the custom NXT firmware...

it was NXC: bricxcc.sourceforge.net/nbc

allquixotic

so what we ended up doing was, after the TA left the room at the end of one of our sessions, one of our team members "borrowed" one of the RCXes (we weren't allowed to take them out of the room) and I found the driver .sys, .inf and .dll files for it and emailed them to myself and the other students

and me and the other CS guy in the group used the RCX in his dorm on his laptop, loaded up the drivers (he thought my knowledge of how to load the drivers manually was really clever), and wrote the C code

and ended up using it in the project and got a B :P

So... one thing I fondly remember tinkering with when I was a little dragonling: Sound Blaster cards, SoundFont banks, MIDI, and audio synthesis.

Journeyman Geek

I might have a PCI AWE32 around here somewhewe

bwDraco

Back in the day, our family PC had a Sound Blaster AWE64 card, and there was this thing called SoundFont banks which contained audio samples from musical instruments and were used to perform musical synthesis. These SoundFont banks had to be loaded onto the card (which, of course, had limited memory), and the card would use the samples in the bank to play back MIDI or other synthesized audio.

Kuala Lumpur's Berjaya Timesquare massive screen got hacked. Perfect meme platform.

Tweeted by paklonginvul on February 8, 2018 at 8:14 PM

bwDraco

There was this program called Viena SoundFont Editor (supplied with the sound card drivers IIRC) which I played with for hours on end. Some old DOS games used SoundFont banks and I opened them in the editor to see what audio the game used.

At the time, CPUs just weren't powerful enough to do sample-based sound synthesis of this sort, which is why these sound cards existed. In modern terminology, these old Sound Blaster cards were "sound synthesis accelerators".

These days... stuff like this is no longer widely used. MIDI playback is handled through the Roland-licensed "Microsoft GS Wavetable Synth" driver, which contains low-quality audio samples and a simple synthesis engine with limited functionality.

Surprisingly, the SoundFont format is still widely used these days (for certain values of "widely used") for MIDI composition.

On my old gaming laptop, I used a program called VirtualMIDISynth which provides a much better sound synthesis engine with the ability to use arbitrary SoundFont banks. It consists of a user-mode driver which handles all MIDI playback; when a program plays a MIDI file, the driver loads the SoundFont bank(s) into memory and uses it to synthesize the music. VirtualMIDISynth is still maintained to this day.

@bwDraco, interesting about the SoundFont editor. I wasn't into synthesis much between 1994 and 2012 or so so missed that era. But since then I've been developing the modular-style software synthesizer Moselle (free download on moselle-synth.com). While the synth is powerful there are almost no "presets" and once I heard of SoundFonts, I thought maybe I should add support for that format...

bwDraco

Interesting...

You can use the FluidSynth library and build on that.

I'll post the actual script in a second

https://gist.github.com/anonymous/45b619e0d7a63d65c02260df9e61127f
Thing is: if I call this script directly, it works fine. If I submit it as a grid job _with_ environment variables (which I need to do because matlab is being an ass about the license) then it throws the error that I posted

ToxicFrog

Matlab? I am so sorry.

Rickyfox

ikr?

Was dealing with all the nonsense for the entire project and in the end it turned out apparently noone wanted to use matlab to begin with. Smh...

ToxicFrog

What version of bash is running on grid vs. locally?

And did they recently install a newer bash?

I think what's happening here is that, somewhere, you have export -f module

Which declares module as a shell function that should be exported to subshells.

Rickyfox

on the server I'm logged into bash 4.2 is running, I don't know about the single nodes of the cluster but I'd assume they're the same

Can I reset the environment variables somehow? Gotta admit I barely know anything about bash

ToxicFrog

This is done via the environment variable mechanism with the BASH_FUNC_ prefix (on newer bash) or just with the name of the function (on older bash)

Try unset module?

type module first to see if I'm right; if it says module is a function or similar

Rickyfox

20:28

I already unset it first

that was a bit too late lol

hm lemme check what the log will say now

ToxicFrog

You could also try env -u module qsub ... to run qsub in an environment where module isn't set.

Rickyfox

oooooh that looks good

ToxicFrog

(my suspicion is that either your local machine or grid recently upgraded bash to a version that uses different conventions for how export -f is handled)

Rickyfox

looks like unset did the job

ToxicFrog

\o/

Hope you didn't need that function for anything :P

Rickyfox

20:36

well, we'll see if I get a mail from uni IT about me setting their cluster on fire or ruining something

Thanks for the help, you might've just saved this project

ToxicFrog

You're welcome!

Note that you'll probably have to unset it every time you log in

It's likely defined in your dotfiles or something (or in the system bashrc)

Rickyfox

yeah I'll make a note so my colleague can see that too

Jonas Stein

@allquixotic so true

ToxicFrog

If you have shared dotfiles (or a shared bindir on $PATH), you could write a wrapper for qsub that automatically unsets it
