This is obviously a bug, but is it a frontend or a backend issue?

Two years ago, a feature was added to Android 12 where the previous audio source would fade out when a different source starts playing (e.g. you start a YouTube video while music is playing).

A post was made on XDA on 18 May, 2021:

Audio focus is determined by the app in question that's playing media. Google explained that when an app requests audio focus while another app has the focus and is playing, the framework forces the playing app to fade out. This will be a nice change because instead of another app abruptly ending its audio stream whenever the user starts another session, Android 12 will nicely fade out the old stream that's lost focus.

I remember being very impressed with this feature and found it satisfying every time. However, after buying a Samsung Galaxy A24 running Android 13, I was disappointed to discover that this feature is missing.

This is yet another reason why I can't wait to install a custom ROM on this phone. For now, though, I guess I'll just have to wait.

Some research I've done suggests that a small idling engine should consume about 0.2 - 0.3 gal/h, which is about 0.8 - 1.1 L/h. However, the following calculations I've done are off by a mile.

At idle, engines typically operate in a rich-running condition, which implies a best-case air-fuel ratio of roughly 14.7:1 (i.e. 1 L~fuel~ / 14.7 L~air~).

According to this article, engines typically have a volumetric efficiency of 15% at idle. This means the volume of fresh air drawn into each cylinder is about 15% of the cylinder's volume.

A 4-stroke engine sucks air into all cylinders in two revolutions.

Using this information, I've calculated the idle fuel consumption for a 1.1L engine at 800 RPM as follows:

rate = (800 rev / min) * (15% * 1.1 L~air~ / 2 rev) * (1 L~fuel~ / 14.7 L~air~)

This comes out to roughly 4.5 L~fuel~ / min, or 269 L~fuel~ / h. What gives?

User jAm-0 has issues getting into and out of his phone's bootloader. He attributes this to the bootloader being corrupt and wants to replace it.

User return.of.octobot provides instructions to allow reflashing the bootloader. One of the steps is to run fastboot flashing unlock_critical, which allows the bootloader to be overwritten.

Overwriting the bootloader is the only way to hard brick most devices, and fastboot flashing unlock_critical tells Android you don't care and are willing to take the risk. Hard bricking makes a device unfixable on the software level.

jAm-0 has another question and receives responses from return.of.octobot and another user, nrage23. Again, no disclaimers are given and the word "brick" isn't even brought up.

jAm-0 hard bricks their phone.

TL;DR How can I equalize my car speakers using an equalizer app like ViPER4Android on my phone?

I just equalized my headphones on my phone using ViPER4Android's convolver feature and a headphone-specific .wav file I got from AutoEq, and it sounds great. Unfortunately, AutoEQ only seems to support a limited range of sound devices, which does not include car sound systems.

I'm not an audiophile, but even I can tell that my car's system's frequency response is terrible, specifically in the low end, where there are specific frequencies that resonate through the car (especially noticeable when the bass frequency changes in a song).

As far as I know, AutoEq's files are made by playing something over the speakers, recording it with a high-quality microphone and correcting it to match some pre-determined frequency response curve called an equalizer target. I was wondering if there's a way to replicate this process using my phone's microphone (I'm not after near-perfect sound quality here, just something that sounds reasonable), and if that would be the best way of going about this.

Consistency

As you may know, a message written in one Reddit client doesn't display the same in another. Here's an example:

```

They also differ in how they render subscripts with parentheses (a^(\(b\))), nested subscripts (a^b^c), and code blocks and lists that immediately follow text.

Lemmy doesn't have these issues, since its Markdown specification is clearly defined.

Images

On Reddit, if you want to add images to a text post, you have to use the Fancy Pants editor on reddit.com. If you attempt to edit such a post on the official app, a third-party app, old.reddit.com or the mobile site, these images simply turn into links. Additionally, you can't attach images in comments.

Lemmy lets you attach images from anywhere, including comments.

In case you haven't heard, CGP Grey is restricting the comments under his videos to users who have been manually approved by him. He mentions in his video about it that you need to sign up in order to be manually approved.

What he doesn't mention in the video is that you need to sign up for his Patreon. If you visit his Patreon page, you'll see that it costs upwards from $3 to sign up.

Bias

One of the purposes of the YouTube comment section is to provide a place for people to fact-check videos, which helps prevent the sharing of misinformation.

The overwhelming majority of CGP Grey's Patrons are inherently fans of him. This means that the opinions of the commenters are artificially biased in his favour, and those who are able to comment are way less likely to point out mistakes and present opposing arguments.

Since CGP Grey does not share misinformation, this isn't a huge deal. However, this sets a precedent for other less honest creators to restrict the comments under their videos in a way that lets them protect their dishonest narratives, while also making money off their Patrons who don't see through their dishonesty.

The YouTube comment section doesn't provide any hint that it's in approve-only mode, so it's hard to tell whether a certain comment section is artificially biased in the creator's favour in this way.

YouTube membership

YouTube allows its creators to set up a membership system for their channels. Users who join these memberships pay a monthly fee in exchange for benefits, just like Patreon. One of these benefits is the ability to participate in a members-only comment section, which happens to be the whole purpose of this experiment. The only downside is that YouTube takes a larger cut than Patreon.

However, this system would still allow non-members to comment in the general comment section, unlike the current system with Patreon. One can only speculate why CGP Grey isn't making use of this system.

Other methods

The current lowest price tier that CGP Grey provides is $3 per month and provides benefits other than the privilege to comment. Patreon allows for lower price tiers, so CGP Grey could add a $0.50 tier that only provides the ability to comment.

He could also use a Google Form or some other bot-resistant way to collect the names of users who should be approved. This could potentially be automated, unlike the current system.

Reddit threads

r/CGPGrey is the subreddit where CGP Grey posts links to his videos, where people on Reddit can comment and deliver criticism. Unfortunately, these comments can only be seen by people specifically navigating to these posts, which is a small percentage of his viewers.

It should be noted that the video covering the experiment doesn't have a Reddit post of its own.

Scam bots and sex bots

CGP Grey claims that the purpose of this experiment is to place a monetary barrier between bots and the comment section, which is exactly what Twitter has been doing with Twitter Blue and receiving backlash for.

However, CGP Grey hasn't mentioned attempting to use ThioJoe's tool to get rid of these scam comments. According to Linus Tech Tips, a channel with over 15 million subscribers, this tool "is so dead simple that it's shocking" and its false positive rate is "roughly zero".
