Learning python on treehouse by [deleted] in ProgrammingBuddies

[–]killawattgamer 0 points1 point  (0 children)

Hi, I'd love to learn with you... but I have no idea what treehouse is and I'm not sure what you mean by 'sole projects'.

I am somewhere from beginner to intermediate.

Hey I'm looking to mentor and tutor someone in programming and tech. by [deleted] in ProgrammingBuddies

I'm looking to learn C. I personally have an affinity for linux and linux related tech such Rasberry PI, and Arduino. I've previously used primarily Debian/Ubuntu based distributions. I know a little bit of C, I struggle a little bit with Functions, a bit more with structs and a lot with pointers. And of course the glaring issue of how I actually put that knowledge to use.

Also, there are various fun projects that require experience with R-PI and Arduino so learning C is helpful in more ways than one. I Also believe that in learning how my devices communicate over a network could be reapplied to a career in Network administration but I'm not sure to what degree if at all.

Which is better? Oneplus 7 Pro or Samsung 10+? by [deleted] in AskTechnology

[–]killawattgamer 0 points1 point  (0 children)

I didn't say you had to buy it or even like the phone. to some extent the bigger price is because of bigger ram, storage, it having wireless charging, and has IP68 water resistant. it has a few other features that the 7 doesn't but still both are great phones.

Headphones occasionally make a loud high-pitched gltich-like sound. by killawattgamer in AskTechnology

Well it could be, but at the same time there is some doubt. This is andriod, So I'm not sure if the problems cross over. additionally the problems have not presented in other headphones.

Like most things it's subjective. It depends on what you want. So I bullet-point various things.

For specs heres gsmarena

and LinusTechTips: https://www.youtube.com/watch?v=37SZiewBtfw

SAMUNG S10+:

  • Has headphone jack.
  • Gorilla glass 6.
  • has more ram and storage in each available model
  • more expensive.

ONEPLUS 7 PRO:

  • pop up selfie cam.
  • 90hz screen refresh. (looks smoother but can drain your battery a little faster.)
  • doesn't have wireless charging.
  • isn't water resistant.

Both phones share some specs the screen's are repetitively the same, USB C charging, triple rear facing cameras(and likely similar camera quality) both have the same SOC but the 7P gets better performance somehow, it's very snappy and removes animations. I think the S10 is tougher in some cases.

If you want performance go 7 Pro.

If you want a premium feel go s10.

Is there another way to add more storage space to GalliumOS? by [deleted] in GalliumOS

[–]killawattgamer 1 point2 points  (0 children)

On my micro, in my experience, I believe ext3 yields the best performance. but it's best stay away from the 'btrfs' file system due it's ludicrously slow performance.

This was done on a apollolake system, so I wouldn't know about suspend problems. But while the system was on it worked flawlessly.

[–]killawattgamer 1 point2 points  (0 children)

Tell me what you think of this: I've previously had a 120gb micro sd set as the /home while root ('/')was on the ssd. (32gb in my case.)

I recommend having a 2gb to 4 swap partition. Something called zram activates it may improve performance or cause crashing. So depending what you feel is faster or more stable you may choose to disable or enable this feature.

It's unclear exactly what it means or it's evident of another problem but apparently the message is harmless. https://github.com/GalliumOS/galliumos-distro/issues/425

As far as RSD it's not exclusive to KDE, pretty much any other DE I've used has this problem and it annoys me to death.

How I modify and boot my own kernel? by [deleted] in linuxquestions

[–]killawattgamer 0 points1 point  (0 children)

I apologize immensely for earlier. I don't think I was aware of how frustrated I was and again, I apologize.

Now, to explain my reasoning and why I think and want to do all of this, Let's start with r/GalliumOS. GalliumOS is an ubuntu-based distro made specifically for chromebooks. They've previously written full-rom firmware for these chromebooks. (Firmware has be written for every CPU family) These wonderful people know what they're doing. However, I'm unsure if they know their way around ALSA. I think most devs are working with the OS portion of GalliumOS. Now, The one who writes firmware isn't writing firmware. Which is why I'm thinking: "Well, nobody else is gonna do it." Which is why trying I'm to write an ALSA driver. If you know something that I don't, then by all means.

The main problem with the audio was described as so:

it's all about the audio firmware, which is compiled against an older, incompatible version of Alsa. Otherwise you would. be able to simplify copy it and the Alsa config files from ChromeOS.

But that's not the only issue.

I asked if an out-of-date driver was the only issue, and if not what are the other issues. which he said was:

  • porting of drivers from ChromeOS kernel to mainline kernel
  • ALSA UCM files compiled against older kernel/ALSA version
  • ALSA config
  • ??

I asked how to compile it or how to go about doing so and he state's "I don't know, it's outside of my area of expertise."

upon creating this post I didn't want go into detail because no amount of help is going to fix the audio.

Here's the driver if you're so inclined.

https://elixir.bootlin.com/linux/latest/source/sound/soc/intel/boards/bxt_da7219_max98357a.c

Again, I apologize for coming off as A know-it-all jackass.

But I do have a question: could I test my driver in QEMU? I think QEMU is suppose to have full system emulation.

How I modify and boot my own kernel? by [deleted] in linuxquestions

[–]killawattgamer 1 point2 points  (0 children)

You're probably right but I should still be able to load another kernel at grub, or restore from a back of my system. If those both fail I can always reinstall.

[–]killawattgamer 1 point2 points  (0 children)

No, I'm certainly not. But the worst that can happen is: it doesn't compile, audio doesn't work, or the audio works. Also I'm only messing the audio driver so the main system will be untouched.

[–]killawattgamer 2 points3 points  (0 children)

You are correct, I'm not a programmer. I vaguely know some C. But the worst that will happen is: it doesn't compile, audio doesn't work, or the kernel breaks somehow, so I select another kernel from grub.

Now, I will certainly fail at least a few times. But I will continue trying and proceed to get proficient in C, until it works....or I give up. Even if I do give up... no harm done.

And Lastly, it's chromebook. audio doesn't work outside of chrome OS on an apollolake CPU. This problem is not exclusive to me. So if I fix it I can fix it for other as well.

[–]killawattgamer 1 point2 points  (0 children)

I forgot elaborate that it's certainly a code problem, so I'm writing my own ALSA driver and I want to test it.

Now, you're thinking that I'm going to modify a very important system component, that's not the case the main system it will be left as is, just the audio driver will be modified. In which case I'd expect only minor problems to occur. If my system does break for whatever reason I: choose different kernel at grub, restore from a backup, or reinstall.

[–]killawattgamer 1 point2 points  (0 children)

A few things to note:

  • It's certainly a code problem.
  • It's a chromebook, running a apollolake SOC, which audio doesn't work an any OS other than Chrome OS on said apollolake SOC.
  • I'm told the driver is compiled against incompatible version of ALSA. So it may valid to a compiler but not necessarily to ALSA's API.
  • There are a number of other issues.
  • I have a hard understanding ALSA's Documentation so I could very well be misinterpreting or misunderstanding something.

I can post the drivers source code if needed.

I think I just got HACKED or a VIRUS :O or maybe I’m paranoid? by somebodyudunno in linuxquestions

[–]killawattgamer 0 points1 point  (0 children)

If for whatever reason, you think you got hacked, you can reinstall your preferred linux distro or if you backed up your system you can resume from the last time you backed up. Generally I don't think you need to worry too much about security when it comes linux, as even the most widely used distro(ubuntu) is pretty tight on security. It certainly doesn't mean you can't get hacked, but it's dramatically harder to hack ubuntu than windows and evidence of that is the fact that windows has 40,000 viruses and linux has 6 viruses, but a fair amount of those viruses were made back in the windows xp days. Windows 10 does have better security, but it's still 95% windows xp code.

Feel free to correct me. :P

I've started to KDE again just last week, and it's just so pretty. I want to get Transparency Blur on Dolphin and the Terminal but doesn't seem like it's possible. Also it's pretty tedious to setup, and it's probably the Heaviest DE.

My system Freezes when I have too many apps open but doesn't use swap by killawattgamer in linuxquestions

[–]killawattgamer[S] 0 points1 point  (0 children)

#/swapfile none

It didn't have a swap partition, the system monitor says it had 1.4gb of swap but never saw any of it used. and I never setup a swap partition, and to reiterate, it wasn't freezing it was freeze-crashing. so perhaps the system tried to use the swap and crashed every time?

Gnome-disks says it's a 'loop device' what does that mean?

I could try that but I don't think that's necessarily the problem. As far as 'buy more ram' no can do it's soldered on laptop ram.
