Port scanning localhost from a webpage has been possible for a long time and does not require websockets.

This article concurs. https://lwn.net/Articles/810414/ io_uring was first added to the mainline Linux kernel in 5.1.

There isn't any open source license that prevents me from not liking it either.

Maybe I just missed this but can anyone tell me what kernel versions support io_uring. I ran the following test program on 4.19.0 and it is not supported:

    #include <stdio.h>
    #include <stdlib.h>
    #include <sys/utsname.h>
    #include <liburing.h>
    #include <liburing/io_uring.h>


    static const char *op_strs[] = {
      "IORING_OP_NOP",
      "IORING_OP_READV",
      "IORING_OP_WRITEV",
      "IORING_OP_FSYNC",
      "IORING_OP_READ_FIXED",
      "IORING_OP_WRITE_FIXED",
      "IORING_OP_POLL_ADD",
      "IORING_OP_POLL_REMOVE",
      "IORING_OP_SYNC_FILE_RANGE",
      "IORING_OP_SENDMSG",
      "IORING_OP_RECVMSG",
      "IORING_OP_TIMEOUT",
      "IORING_OP_TIMEOUT_REMOVE",
      "IORING_OP_ACCEPT",
      "IORING_OP_ASYNC_CANCEL",
      "IORING_OP_LINK_TIMEOUT",
      "IORING_OP_CONNECT",
      "IORING_OP_FALLOCATE",
      "IORING_OP_OPENAT",
      "IORING_OP_CLOSE",
      "IORING_OP_FILES_UPDATE",
      "IORING_OP_STATX",
      "IORING_OP_READ",
      "IORING_OP_WRITE",
      "IORING_OP_FADVISE",
      "IORING_OP_MADVISE",
      "IORING_OP_SEND",
      "IORING_OP_RECV",
      "IORING_OP_OPENAT2",
      "IORING_OP_EPOLL_CTL",
      "IORING_OP_SPLICE",
      "IORING_OP_PROVIDE_BUFFERS",
      "IORING_OP_REMOVE_BUFFERS",
    };


    int main() {
      struct utsname u;
      uname(&u);

      struct io_uring_probe *probe = io_uring_get_probe();
      if (!probe) {
        printf("Kernel %s does not support io_uring.\n", u.release);
        return 0;
      }

      printf("List of kernel %s's supported io_uring operations:\n", u.release);

      for (int i = 0; i < IORING_OP_LAST; i++ ) {
        const char *answer = io_uring_opcode_supported(probe, i) ? "yes" : "no";
        printf("%s: %s\n", op_strs[i], answer);
      }

      free(probe);
      return 0;
    }

Right, but they must retain the original copyright notices and provide the source code. I'm asking the person who bought the software to verify if this is the case.

I don't mind so much someone selling my software on a CD. What I do mind is that they changed the name to trick the buyer. Perhaps I should be using a different license.

Sorry, but I love caviar. In fact any sort if fish roe is good. It does not have to be expensive. In Russia they eat fish roe/caviar on buttered bread for breakfast. It's really good.

I had the same experience. I called AirBnB and they acted like it was a really strange occurrence and they would look into it. My review never appeared on the host's page. I have zero trust in AirBnB.

One person has died in the US. It's not time to panic. I expected more logical comments here.

> it's a another red-haired woman

Why is it significant that this post was from a woman or that she has red hair? This comment sounds like a backhanded compliment, at best.

No closed loop stepper support at this point. We are taking about making a driverless version of the Buildbotics controller which you could pair with any external driver or closed loop steppers.

By definition, most people don't need to worry about becoming famous and its consequences.

An LASER cutter is a really productive device to have around. It's very easy to create 2D parts.

Another way to go Open-Source for a lot less money (~$1500) is to buy a K40 on EBay and refit it with a Buildbotics controller.

The other day I needed a faceplate for an outlet with a circular 240v US dryer plug and a two port 120v US plug. I couldn't find anything at the hardware store that would work but I found drawings for the junction box and plugs online. After an hour or two with LibreCAD and CAMotics, I was ready to LASER cut my faceplate from 1/4" poplar. I was really happy when it fit exactly the first time. Now I keep looking behind the dryer to admire my handiwork.

We play that too. Bluetooth or crazy.

I believe this has to do with which Akamai server ends up handling the page request.

One of those leads to this: https://apps.nsa.gov/eqip-applicant/showLogin.login

This is what Google used to be like. They have fallen a long way from this high ground.

"Don't be evil" used to be Google's company moto. It was downgraded to being just part of the code of conduct.

HN is pretty good at moderating discussions. Which is the main reason I come here. Still, I've seen plenty of beef only thinking here and I too have been guilty at times.

It can be quite frustrating when you make an observation about someone's comment only to have them automatically assume you were in disagreement. It's good to assume a generous interpretation. Since tone is so hard to gauge on the Internet, discussions quickly devolve otherwise.

Folding@home is working on a different problem. Folding@home finds the path a protein takes to arrive at its final structure, not just the final structure. One of the main goals is to understand protein misfolding or where on the path things go astray to result in disease.

After all these years, we are still at it. New methods are regularly evaluated and the simulation software is being refined all the time.

Nice. Now my wife and I can both stay logged in to our email. I've wanted this feature for 15 years. Now, bring multi row tabs back and FF will be awesome again.

The only feature I really want FF to bring back is multi-row tabs.

Customers saying "this has changed recently" means little. For example, I found such reviews for a pet flea product. When I investigated further I found similar reviews both very recent and going back 4, 6 and up to 8 years. Perhaps there are random bad batches but I suspect that part of the problem is the perception that a product is different. People often fail to recognize other factors such as changes in their own usage patterns, or in this case, changes in their local flea population.

The bullshit is that politicians continue to only take action against consumers when the real polluters, corporations and the military, continue to go unchecked because lobbying pays.

> I've been thinking about wood CNC myself. What kinds of tools are used these days?

Check out the https://buildbotics.com CNC controller and the https://CAMotics.org CNC simulator. Both are Open-Source. These are my projects.

You should check out https://tplang.org/ It's Open-Source and part of the https://camotics.org/ CNC simulator. TPL is JavaScript with built-in extensions that make generating GCode programmatically and visualizing the results much easier. Disclaimer, I am the author.

What's to stop someone from passing many duplicate notes?

Broken ankles are another common low speed injury for new riders.

How about pug.js for HTML templating and Stylus or Less for the CSS. Then just generate a static site. Static sites are fast and fast is always good SEO.

Finding the right parameters to cross compile each dependency you need is tedious. Sure some packages are easy to cross compile but it's much easier to set up an emulated build environment and then compile everything normally.

A Makefile tracks a dependency tree and rebuilds what has changed. Docker has a dependency list and has to rebuild everything following any change. Seems to me like we've gone backwards.
