00:16:29 <MrMobodies> Electrohead, "Signs of a stroke "Incoherent Speech I love Microsoft teams""
00:16:42 <MrMobodies> That is exactly how I feel when talking to some chatbot over the phone
00:17:41 <MrMobodies> My test tightening, frustration and anger build up not getting where I want to get to.
00:18:26 <MrMobodies> one time I came off the phone yelling and shouting and had what seems a bit like a heart palpatation.
00:18:43 <MrMobodies> Oh yes that was the Ebay chatbot over the phone
00:18:59 <MrMobodies> Jump through many hoops now to talk to a human
00:19:13 <electrohead> lol

00:25:35 * arch flicks a booger into electrohead's mouth while he is busy laughing
00:29:05 <MrMobodies> Later on I am hoping to get rid of this thing:

00:30:52 <MrMobodies> What the hell were they thinking when they started to intefere, dim, and fade out things I might still be trying to look at all because it is in an inactive state. They say it is a "backdrop" and focus element. I find flashing and fading the opposite, very distracting.
00:31:43 <MrMobodies> so many settings imaginable, but for that which seemed introduced in 2019
00:32:23 <MrMobodies> and it spikes the CPU everytime it does that... the stupidity.

00:34:27 <MrMobodies> Joke: Now isn't that clever, putting on an animation in the guise that it'd help the user to focus more by hiding content, content that they might still be trying to read whilst affecting the the performance.
00:34:53 <MrMobodies> Bet they copied that idea from a webpage.

01:35:26 <blastsnoop104892acb> Kuschelpony what do you think about using a fet bridge and a smoothing capacitor where some type of signal/waveform is applied to the fets to allow some reverse flow?
01:36:26 <Kuschelpony> yes sure, just emitting a hell of harmonics because the bridge can only switched hard to maximum voltage
01:37:14 <Kuschelpony> now run the bridge with high frequency PWM and add a small inductor in series (neglible at mains frequency but choking off high frequency current)
02:08:33 <blastsnoop104892acb> might be something to investigate
02:09:31 <blastsnoop104892acb> I'm trying to think what the pwm would look like
02:11:14 <blastsnoop104892acb> if it were constant frequency/duty across a cycle would the smoothing cap loose all of its energy
02:23:42 <DHess_US> Look up how active power factor correction works.
02:24:40 <blastsnoop104892acb> are you talking about displacement or distortion PFC?
02:24:47 <DHess_US> Use a boost converter configuration and drive the switching FET to create an average current proportional to input voltage. Now the output capacitor is sized to filter 120 Hz ripple.
02:25:01 <DHess_US> Just like with a bridge rectifier capacitor input.
02:25:43 <DHess_US> Could even use a standard APFC IC to do it.
02:26:21 <blastsnoop104892acb> distortion PFC, this is for displacement
02:27:14 <blastsnoop104892acb> inductive generator -> capacitance -> rectifier
02:27:20 <blastsnoop104892acb> to replace the capacitance
02:47:05 <Kuschelpony> Dhess, you ight have missed conversation from previousdays, we are taling here about displacement AND distortion factor correction, by using an class-D amplifier that injects opposite phase reactive currents, in paralell to compensate an otherwise low-PF load

07:02:21 <MrMobodies> Fed up with it
07:02:44 <MrMobodies> The classic things work but it is another form of stupidity that will affect me
07:03:17 <MrMobodies> In Kali XFCE, Say I have two windows opened to copy files over to the other
07:03:50 <MrMobodies> on selecting the second window, the scrollbar FADES out of inactive one.... UTTER STUPIDITY!
07:03:58 <MrMobodies> How am I suppose to TRACK where I am
07:04:21 <MrMobodies> and they have that stupid SHADOW that I can't seem to switch off
07:05:56 <MrMobodies> https://askubuntu.com/questions/711685/how-to-disable-the-hiding-of-scrollbars-in-version-16-04-and-up
07:05:56 <EEVBot> [url] autohide - How to disable the hiding of scrollbars in version 16.04 and up - Ask Ubuntu | askubuntu.com
07:06:53 <MrMobodies> aaah I see it is Gnome thing
07:07:20 <MrMobodies> GTK_OVERLAY_SCROLLING": "0"}
07:09:32 <K> goddamn gnomes!
07:13:50 <MrMobodies> Console in Kali is pathetic
07:14:15 <MrMobodies> It UNDERLINES everything so I don't know if it is there or not.
07:14:46 <MrMobodies> they put if behind this opacity transparent... the whole thing is a joke.
07:15:27 <MrMobodies> when I am typing things in the command line and everything appears underlined with no options turn that off
07:20:05 <MrMobodies> https://i.postimg.cc/FF9WSk4Y/IMG-20260617-221654-DRO.jpg
07:33:21 <MrMobodies> I think I have a solution, install KDE over it and remove XFCE
07:33:58 <MrMobodies> and they'd be settings for that
07:38:43 <MrMobodies> I get it from this thread:
07:38:44 <MrMobodies> https://www.reddit.com/r/linuxsucks/comments/1p27mb0/why_wayland_sucks/
07:39:28 <MrMobodies> It is about LOCKING OUT the user from the basic functionality and adjustments.
07:40:50 <MrMobodies> If they didn't have all this decorative flashy crap on, where it's an optional extra and worked on in future for those that are "screaming in th street for it" then it wouldn't be a problem.
07:46:04 <MrMobodies> Well that worked, used Kali to copy over the Classic theme files to suppress that behaviour onto Xubuntu XFCE
07:46:06 <MrMobodies> https://i.postimg.cc/gY2TSBtN/IMG-20260617-224329-DRO.jpg
07:46:15 <MrMobodies> but I am still NOT PLEASED
07:46:24 <MrMobodies> shadows are still there.
07:46:51 <MrMobodies> the title bar (user-Thunar) STILL fades out when the window is inactive where I can't read it
07:47:50 <MrMobodies> I am starting to think the people making these changes don't use these things themselves they just make assumptions about the users
07:48:32 <MrMobodies> yep opened firefox and it's massive tab bar FADE VERY noticably annoying
07:48:46 <MrMobodies> and that shadow

08:09:55 <MrMobodies> Wayland "Feature Frozen"... turn off backdrop is debug only and may not be there in future (sounds CONTRADICTORY to me) if the debug option can be removed then it's NOT "feature frozon". Sounds to me like words from a bunch of arrogant, overzealous people working on it who think their entire usebase is stupid and need micromanaging for everything litle tiny thing they do.
08:10:55 <MrMobodies> and so small minded, the other inactive windows open confuses their little minds that they it faded out
08:21:25 <MrMobodies> Downloading VIPNIX
08:21:37 <MrMobodies> a lightweight distro
08:22:20 <MrMobodies> https://vipnix.com.br/site/wp-content/uploads/2026/05/VirtualBox_livecd-vipnix_02_05_2026_04_53_16-1-1024x640.png
08:23:24 <MrMobodies> 4.4gb in size so it's isn't lightweight like i though
08:33:40 <MrMobodies> With Rufus and a USB C copied that 4.4gb over in like 6 seconds
08:54:11 <MrMobodies> it's got GTK3 on it with that stupid fade thing
08:54:37 <MrMobodies> so many setting but the one to stop it

10:07:14 <MrMobodies> giving SYSLINUX13 a go, it looks promising at the moment
10:44:19 <MrMobodies> FINALLY:
10:44:20 <MrMobodies> https://i.postimg.cc/HLLsvDVp/SYSLINUX-Tradional-OK.jpg
10:44:42 <MrMobodies> The ONLY theme that does not feature that annoying fading stuff
10:45:11 <MrMobodies> the scrollbar does light up on hover but it doesn't slowly fade, it snaps and it doesn't seem to spike the performance
10:46:07 <MrMobodies> that must be the next big TREND, fade/flash over everything hovered over.
10:47:02 <MrMobodies> Found that turning off software compositor gets rid of the stupid shadows
10:48:19 <MrMobodies> much as ease I found something

13:18:50 <Nothing\> man i'm so confused about what to do about my bandages
13:19:46 <Nothing\> nobody told me anything about how/when/if to change them. I have a few that the doctor gave me and he said I could shower, but he also put steri-strips across the incision to keep it closed, so I feel like those would come off the second i pulled the bandage off to change it
13:20:32 * electrohead packs the bag, runs
13:21:22 <Nothing\> and the bandage has this really tacky adhesive that's impossible to wash off without superfluous amounts of rubbing alcohol, which turns it into white goo that you just sort of pick off. It's annoying where the bandage has come up on the corners. Between the 30c+ temps and excessive sweating, it's turned into a liquid that's just smeared itself all over my neck and shoulder
13:21:37 <Nothing\> electrohead, god if only i could do that
13:22:00 <Nothing\> there have been times i've been tempted to call the doctor and just demand he schedule surgery to remove the plate asap
13:22:11 <Nothing\> just like, fuck it, i'm out. too creepy
13:22:32 <Nothing\> realistically i'm gonna stick it out though, i have no choice
13:22:57 <Nothing\> but i do have to get it removed some time in september or october so i don't even recover once the bone heals lol
13:24:30 <Nothing\> and my bicep and tricep have withered down to the size of a tiny filet minon
13:24:40 <Nothing\> my left arm looks anorexic
13:25:05 <Nothing\> yet, my left boob grew by 1 cup size because of the hematoma. How bout that?
13:28:58 <Nothing\> it was kinda neat, at one point they were doing a nerve block with local anesthetic to numb/paralyze my arm, shoulder and the left side of my chest. The procedure was like awake brain surgery. They had to stick a big needle in my shoulder/neck area into a nerve plexus I guess like a bundle of nerves using ultrasound to guide them
13:30:08 <Nothing\> they couldn't knock me out fully because they had to be able to figure out where the needle was. They had an electrode at the tip that would stimulate my nerves and make my arm or hand twitch, and i had to tell them what i was feeling until they had it in the right spot
13:30:49 <Nothing\> definitely one of the more unique experiences i've had and after the sedation, it creeps me the hell out to think about haha
13:32:02 <Nothing\> when they brought out the needle they were gonna use i could feel the color drain from my face. Thank god for that sedation. I would have just gone full fight or flight otherwise
13:33:20 <Nothing\> i can't help but feel like breaking a bone or getting an orthopaedic plate installed is kind of like a right of passage a lot of us go through at some point in life. Even if it's a fake hip at 75
13:41:10 <MrMobodies> Absolutely pissed, In Kali Linux they have a STUPID overflue FOCUS RING
13:41:47 <MrMobodies> Buggy horrible, glitcchy and they seem to care more about adding decorations that I can't turn off.
13:42:48 <MrMobodies> oops it's a feedback thing not focus ring

21:58:50 <blastsnoop104892acb> Say you have Inductive AC -> PFC Totem -> AC/DC -> Buck -> Capacitance
22:00:04 <blastsnoop104892acb> The PFC is creating a voltage higher than the capacitance which resolves distortion but it's also varying its duty to create a voltage where the voltage/current align.
22:00:21 <blastsnoop104892acb> (sorry should say the Totem PFC is doing the AC/DC
22:00:23 <blastsnoop104892acb> )
22:02:08 <blastsnoop104892acb> So say the capacitance voltage is at 0 and the buck has a duty which sets a fixed load on the DC. The feedback loop of the PFC prioritises phase, so the DC can drop.
22:02:51 <xstevia> o/
22:03:35 <blastsnoop104892acb> If the buck applies a greater load the DC voltage drops further because maintaining it is a secondary priority.
22:05:30 <blastsnoop104892acb> Which means MPPT is not a thing, right?
22:07:31 <blastsnoop104892acb> Or look at it another way. If the Buck doesn't exist or is at 100% (passthrough) the PFC will still be applying a duty which makes the voltage/current phase zero. Even though the voltage will be at the level of the capacitance.
22:12:00 <blastsnoop104892acb> So in summary if the load is high enough to absorb more than the AC can provide, and the PFC hasn't hit its limits, it will by its nature be operating at MPPT.
22:12:08 <blastsnoop104892acb> How does this sound?
22:12:13 <blastsnoop104892acb> :)
