We should port it to Rust.

In theory you would be right. In practice you have to ask all of your competitors for permission to change anything, and all the old copper is still there. They never actually swapped it out for fiber! You cannot take out any of their old copper, even though you’re sure it’s not in use by anyone, to make space for your new fiber.

Ziply is a regional ISP. They serve the states of Oregon, Washington, Idaho and Montana. Here’s a map showing their backbone links: https://ziplyfiber.com/~/media/Residential/modules/Columns--...

> I can also get 400Gbit in my office…

Sure, but remember that we’re talking about _residential_ services here. Ziply Fiber offers 50Gbps to all residential fiber customers. They also sell IP Transit services to businesses at higher speeds, but we’re not talking about those.

False! Ziply Fiber offers speeds up to 50Gbps. https://ziplyfiber.com/internet/multigig

It’s not to keep malware from walking the heap, it’s just a simple protection against simple buffer overflow attacks. If a process running on your computer has a fixed–sized buffer allocated on the heap and I send too much data to fit in the buffer then part of what I send will overwrite whatever comes after that buffer in memory. Well, that means that it will overwrite the heap header objects that windows uses for memory management too. That can be an important step in exploiting the overflow bug.

But Windows picks a random number for each heap and XORs the heap header with it. This means that every time you run the program the headers have to be XORd with a different random number before Windows can understand them. I have no way of predicting what that number is, so the malicious data that I send won’t be XORd with the right number to fool Windows.

The title seems to describe exactly what the video is about. What made it seem like clickbait to you?

Wow, 102°F. That’s just an ordinary summer day in most of America.

It’s pretty shameful that the hospitals couldn’t handle the influx. Didn’t they expand capacity after COVID?

Not arguing, just saying that sometimes things come with compromises. It shouldn’t be surprising to anyone that some expansion cards don't fit in the expansion slot. There’s always going to be _something_ that needs a bit more space.

Now you’ve got two things plugged into your laptop, instead of one that sticks out by an inch. :)

There’s nothing to “get”. The circuit doesn’t fit inside the slot for expansion cards. You could plug in a dongle instead, but then you’d have a big hole in your laptop with a cable sticking out. Or you could just get a wider laptop bag. They make them in multiple sizes, you know.

> The OP didn't claim you didn't provide specific feedback, it was that they were entirely ghosted mid-process. And that others said the same.

Eh, if even a small percentage of those emails end up in a spam folder then there are going to be people who think that they were ghosted. They didn’t ghost me. Alas, they didn’t hire me either.

But surely the photo has the same value to you no matter how much effort it took. Sitting outside in the cold next to your telescope while you take the photo doesn’t make the picture more valuable than sitting inside at your computer taking the photo.

It’s worth noting that the latest trillionaire lowered launch costs by ~10×. It has never been cheaper to launch a telescope into space. I’m surprised that no universities have launched their own space observatories. Harvard has a $50 billion endowment, but all they ever seem to spend it on is more administrators. They could launch a dozen space telescopes without making a dent.

I don’t think the telescope has to be sitting next to you. Actual astronomers take pictures remotely all the time. They don’t ride a shuttle up to the Hubble Telescope when it’s their turn to take pictures with it, they put coordinates into a website. Even most ground–based observatories are often operated remotely. Many of them are visited by astronomers too, but more and more that’s an optional step.

Many astronomers work at yet another remove from operations. They don’t even take the pictures themselves! They collect data from other people’s observations instead! A lot of modern observatories collect so much data that there’s not enough people to look at everything in detail. Whole–sky observatories that take hundreds of photos to image the whole sky every night, satellite missions like GAIA that observed a billion stars to determine their position and velocities, etc, etc.
