Can ARM architecture completely replace x86 CPU's?

.

.

assuming all apps and drivers will convert to ARM in the upcoming future, is it possible to completely replace x86 architecture?

from what I heard, the reason that every PC is using x86 is that apps and legacy stuff are already built on x86 and it became a standard, so is the only reason we haven't used ARM is the app support?

What's the difference between CR, LF and CRLF in text files?

Recently got a text editor on Android called Xed Editor. In its settings, I noticed there was a setting for line *ending, that allows one to switch between:

  • CR (Macintosh)
  • LF (Linux)
  • CRLF (Windows)

On saving a text file as either CR or LF, its size was about 93.8 KB. Switching it to CRLF the file size increases to 101 KB. Upon opening the different file versions on Notepad on Windows, they all just appeared similar

So...

  1. What's the difference between the different line encodings?
  2. Should I use CR/LF just to save on some space?

Is parametric speaker a nuisance or a weapon in disguise?

Take a parametric speaker. Take it three apartments above yours. Nearly at 75 percent volume, place it face downwards, but not floor, ask someone to hold it. Now play music on another regular bluetooth speaker in front of it. Do not play anything on parametric speaker. Just play music on regular speaker adjacent to it. Do not face regular speaker downwards. Play music on regular speaker, rather pocket size bluetooth speaker like JBL Go, on 25 percent volume. Results would be good if someone holds those speakers together and does not place parametric speaker on floor. Hold the parametric speaker face down at 75 percent volume. Hold regular speaker face towards parametric speaker. When nothing is playing on parametric speaker, it still emits ultrasonic waves. You can listen to the music at the exact spot three floors below. And this cannot be blocked. No soundproofing solution can block this.

Why doesn't Reddit have a native playback speed option for videos in 2026?

Reddit launched its native video player back in 2017.

9 years later in 2026, there's still no way to change playback speed. No 0.5x, 1.5x, 2x. You're stuck at 1x.

Every other major platform has had this for years. YouTube added it in 2010. TikTok, Instagram, X, Twitch all have it now.

Since HTML5 video supports playbackRate natively, it doesn't seem like a technical limitation.

Is there a reason Reddit hasn't added this? Has Reddit ever said anything about it?

I just want 1.5x for long videos and 0.75x for news clips.

Any monitor around 3-4 inches that can mirror my phone (galaxy android) screen and can play YouTube?

Any monitor around 3-4 inches that can mirror my phone (galaxy android) screen and can play YouTube

Wanted to try to do a DIY phone mount for multi tasking while watching various tutorials for things and the thing I got that hangs around my neck with a goose neck tends to hurt. Wanted to make it kinda a mix of a dragonball scouter and headphone look and figured a screen size like that would be pretty manageable without blocking vision. I could go up a bit too like 4.5 inch. Just kinda looking for options since seems like on amazon lot of them involve stuff like arduino and raspberry pi and while I am planning to try learning arduino stuff I don't know if that type of tech is meant for phone monitors (most displays were for simple statistics) and I would like to see how I feel about the arduino before moving on to raspberry pi. I don't tend to get a lot of time to myself and the work I do is solo so even if it looks a bit silly it's not a issue and would like to at least improve myself if I'm going to be working long hours plus im a artist and a monitor like that could do some interesting things for tech aesthetic cosplay options.

Ideally wireless but I could probably run a long usbc cable between phone and monitor

What's a good security camera for a reasonable price?

For years, we have had people come by throwing their trash out by our road. Cups, cans, bottles, chip bags, etc.

It's almost always in the exact same spot, around a 30 ft distance that they throw it on the side of the road

My brother and I have took the time to pick this trash up, many people have come by seeing us picking up this trash, yet it's still thrown out in the same spot

I'm starting to take it personally, and I'm sure it is deliberate and intentional

I would like to install a camera capable of capturing the assholes responsible, and clear enough to capture their tag number from 50ft or so away (the only place I can get the angle right to see who's throwing the trash out)

I would appreciate any suggestions

New landline without spam and robocalls?

I am trying to understand what my options are for getting a landline these days. It would mostly be for kids to use. What's the recommended way to set these up these days? And I am wondering if there's a way to get a new line that wouldn't be plagued with robocalls and scammers, or if that will inevitably become part of its reality no matter what. I've seen an option where you can reject the robocall, which doesn't quite work for us as we just don't want the phone to be ringing at all unless it's a legit call from a friend or family member. Possible? Any ideas?

Meanwhile, my cell phone is also plagued by spam...

Could modern operating systems implement a universal “child mode” controlled by a single toggle?

Most devices already have parental controls, but they’re often complicated and inconsistent across apps and platforms. So this can make them difficult to use for parents

I’m wondering if it would be technically feasible to simplify this into a single “child mode” setting where a parent just selects an age range, and the OS automatically applies restrictions such as:

- Blocking age-inappropriate apps
- Filtering websites and search results
- Limiting social media and messaging features
- Applying screen time limits
- Controlling what content is shown across apps, browsers, and media platforms

The idea would be that parents only need to enable it once. After that, the rules and blocked content lists would be centrally managed (e.g. by the OS vendor or a government digital safety authority) and automatically updated.

The system wouldn’t access personal data on the device — it would only enforce restrictions at the OS/network level.

From a technical standpoint, is this actually practical across modern devices and the open internet? What would the main challenges be ?

Is it a bad idea to plug a random USB I found into a public computer?

I found 2 USBs on the ground, in some bushland. I’m really curious as to what could be on them but don’t want to plug them into my personal devices in case they contain malware, etc. Would I be an asshole for taking them to my local library and plugging them into the public computers there? Is that a bad idea?

How much does memory usage from browsers really affect modern computers?

I've encountered people who will get very particular about the memory usage of their browsers. And when I hear it online I assume these people must be running on a potato or something. But then I met a couple people who had this concern on their laptops which were totally standard, a few years old (think typical lenovo/dell work laptops with 8-16gb ram), and I inquired whether it really affects performance to use firefox vs chromium based browsers and they seemed to think it did, or that it would affect the lifespan or something.

I'm not really versed on this but wondering if someone could explain the reasoning here.

Is there a product that's like a doorbell but you can press something that will show "come in" or "busy" to the person at the door?

needs to be controllable via app or a remote device that works from the other side of a wall, not like a tv remote.

so kind of like a recording studio/radio station "on air" light but if you didn't turn it on ahead of time and someone knocks, you can turn it on remotely without people on your video call being aware of it.

think working in a home office and a deaf family member knocks and you want to be able to say "come in" or "busy" to them.

and needs to not be over $50.

Best way to keep multi-city event setups consistent?

We’re planning a roadshow across six cities, different venues and local teams are already asking for different setups. My concern is ending up with the wrong device counts, settings changing between cities, or equipment getting lost between returns and redeployment.
For anyone who has managed a multi-city event, did you build one standard setup for every location or adjust it city by city?

A lot of sites allow you to export/download your own data. What sites do you think lead to the most interesting data about yourself?

Obviously, this would depend on the services you use, and how heavy that use is.

Am curious about people's thoughts on the data that would reveal the most interesting insights about yourself

And what sites are worth requesting your data for analytics?
