Hi everyone, I’m not a security expert, my main interests lie elsewhere, but I think I know enough to hold my own in a discussion with a friend.

Today a debate came up with him about the possible attacks that could target a home server (a typical Raspberry Pi) hosting a single and light HTML page.

My take is that in 2026, with the average resources a Raspberry Pi now has (usually 4–8GB of RAM), it’s no longer realistic for a single machine to pull off a resource-exhaustion attack (things like Slowloris or other slow-HTTP techniques). He disagreed, claiming it’s still possible, and said there are other methods too, though he didn’t explain how.

I’d like your opinion on whether what I said is wrong or not. Either way, it’ll be another chance for me to learn something.

Good morning, I’m a guy interested in radio and history.
Being European, I don’t know much about the Vietnam War, aside from the basics taught in school.

A friend of mine recently bought a PRC-25 radio on eBay, which I understand was widely used in Vietnam. Its specs don’t seem too impressive, though: low power, a matched antenna (I think through an internal tuner), and therefore limited range

I’d love to hear some stories from radio operators who served in the Vietnam War, especially anecdotes about this radio and how it was used, given its limited range.
Thanks in advance to anyone willing to help and share their experience.

I'm really new to this world, and I'm fortunate to already own two microscopes (a stereo and a classic KONUS).

However, I find observing with a stereoscopic microscope very simple and intuitive, using it only to observe a few insects.

As for observing with a classic microscope, I find it more difficult because I feel like I "don't know" a lot of things and I'm afraid I might damage it.

For example, a couple of times I observed something without using slides (I didn't have any) and I smeared the lens, which I fear might affect subsequent observations.

I read online that a solution of distilled water is often used to prepare slides. However, I'm wondering how I can ensure that when I take the water from the bottle, I don't inevitably pick up bacteria or plastic particles that might be contained in the container or pipette.

Do you have any suggestions on this? Also, I imagine demineralized water from the supermarket isn't suitable, right?

A few months ago, I was lucky enough to find a Wild stereo microscope for €30.

However, it was missing some parts (the support structure, for example), which I'm slowly building.

Now I'd like to buy some eyepieces and an auxiliary lens that will allow me to observe insects at decent magnification. Since I can't afford to spend that much, I was considering a 2x auxiliary lens from Mechanic, a brand I found on AliExpress that seems a bit shabby.

I was also thinking of replacing the eyepieces with variable 5x-10x eyepieces. Do you have any suggestions?

Maybe I should focus more on eyepieces before buying an auxiliary lens? Or maybe 2x is too much? (I currently have a 0.5x lens)

Unfortunately, I'm in Europe and can't buy original parts from the United States (aside from the very high price for me, I'd also have to pay a lot in shipping costs).

How do you handle channel lists that are scraped online? I uploaded a list yesterday morning, and within 10 hours it was no longer working. This forced me to upload a new list and waste more time.

Is there a more efficient way to always have lists available?
