it's a 429 error, so the developer who posted this is an idiot. they're not even wrong. the 429 doesn't even touch twitter's infrastructure. the HTTPS TLS terminates at a Google VM, which gets relayed depending on the VIP used to hit it, but the traffic never gets past that Google VM. This is literally /HOW/ companies deal with DDOS.

Re:Twitter Is DDOSing Itself on Sunday July 02, 2023 @10:29AM (#36561808)
This web developer thinks Twitter is DDoSing itself ... but those are 429 status codes. In that case, I'm not sure this guy is capable of tying his own shoes in web development, although there's definitely a problem in the Javascript client.

It doesn't matter though because the left will simply go along with whatever seems to support their stance. I guess Elon is their new object of derision, replacing Trump.

For apps as large as Twitter, they use CDN's or PoP to scale, which means that request returning 429 isn't actually hitting the datacenter.

Of course, "one does not simply use a CDN..." so actually determining how this guy is wrong is another question entirely.

Twitter uses Anycast with VIP's proxy TLS sessions to its data center via VM's in Google Cloud. However, it's likely that the GCP VM's are getting the DDoS, depending on which of TLS terminations it hits. Based on the VIP used to reach the GCP VM, it determines how to proxy the traffic, implicitly determining the routes taken.

It's unlikely that the traffic makes it beyond this, though it depends on proxy configuration. Some pass through and others don't. The first article below indicates Twitter terminates at GCP and, overall, implies a secondary TLS connection to their data center.

The rate of requests in the article's video implies the TLS session doesn't time out. The GCP load balancer is simply handling the traffic and staving off DDoS. This is what you're paying for anyways.

there should be one set of diffusion imaging scans in there. as for the strength, I'm not sure.
Re:MRI Scans of a person's brain on Sunday January 24, 2016 @05:50AM (#10962163)
hey! yeh, everything's going well. the scans were done to help diagnose some things about 2 years ago. nothing turned up in the scans though.

thanks for tweeting me earlier. i had no idea this was on Hacker News! lol

Re:MRI Scans of a person's brain on Sunday January 24, 2016 @04:17AM (#10962015)
I don't think we need to scan 100% of the brain in molecular detail in order to read & preserve the information. It should be possible to observe the circuitry at a higher level and recreate an approximation -- though it'd be just that, an approximation. Additionally, much of the information could be compressed to a much more lightweight format than digitizing the physical neural networks of the brain.

Digitizing a static physical model of the brain is problematic in itself. Many regions and structures in the brain are likely structurally dynamic. That is, the neural circuitry could change structure from day to day and this is definitely true over longer timescales. So it'd be much easier to read the data from the brain into another format rather than emulate the physical structure of the hardware.

I've thought a bit about information could be read from MRI scans such as these. In the absence of higher resolution data, I don't think there could any memories retrieved. I don't know the low-level details of how MRI data is encoded, but I do know it is recorded in slices. To retrieve memories, you'd need to read 3D regions from the brain. And it'd need to be much more high-resolution.

hmmm, good point. i think the copyright issue would be fairly complicated here ... and you'd need a good lawyer basically. it'd likely hinge on how you constructed the argument.
Re:MRI Scans of a person's brain on Sunday January 24, 2016 @04:01AM (#10961994)
Also, I wanted my brain to be online in a widely distributed, public manner. In case of robot apocalypse of course. Hopefully, a quantum computer in the future would have low-bandwidth write access to my brain in the past. Quantum mechanics. Then I would be one of the earliest widely-distributed, targetable maps of a human brain on the public internet. And the people of the future could avert a worldwide AI disaster by pinging memories directly into layers of my brain. A la Steins;Gate, if haven't seen it, you should.

Anyways....

Re:MRI Scans of a person's brain on Sunday January 24, 2016 @03:56AM (#10961988)
For the record, i wanted to post my brain online for many reasons. First of all, I did it for science of course. It'd be great for more of this data to be available online for people to study and work with.

There are many anonymized datasets available on Radiopaedia. http://radiopaedia.org/ I've spent quite a bit of time studying neurological conditions on that site and on wikipedia. Those are more useful, but anonymized. I'm not sure that there are many healthy MRI datasets available there, which makes it more difficult to statistically model MRI data.

I'm hoping to use Nipy and Dipy to create visualizations of my brain. In particular, i'm hoping to recreate some of the Diffusion Tensor Imaging work in this talk by Ariel Rokem: https://www.youtube.com/watch?v=HdrSZtB0uX0. However, i'm not sure if my DT images are high enough resolution.

I also did it for philosophical reasons. I believe that all digitized information past and present will be inevitably become known & public post facto. It's the nature of information & knowledge in our technological world to distribute itself until the world converges on total information omnipresence. So if, in the end, all [digitized] information is known, then there is no point in hiding information. This is more of a philosophical viewpoint though. obviously it's impossible for all information to converge in this way.

But this is true even of our own minds. And if our mind can be digitized from our brain, this also has interesting security implications. If you've seen the show stitchers, then you know what i mean.

Under no circumstances was this done in the name of art.

Re:MRI Scans of a person's brain on Sunday January 24, 2016 @03:24AM (#10961939)
