Comment Concerned about bandwidth? Use a tarpit (Score 5, Interesting) 34

Back in the day, we used to run "tarpit" SMTP servers which looked like an open mail relay but ACK'd incoming packets only just barely fast enough to keep the remote client from timing out and giving up. The theory was that tying up spammer resources was a net good for the internet, as a sender busy trying to stuff messages through a tarpit was tied up waiting on your acknowledgement, reducing their impact on others.

Similarly, perhaps the right answer here is to limit the number of concurrent connections from any one network range, and use tarpit tactics to rate-limit the speed at which your server generate contents to feed the bot -- just keep ramping down until they drop off, then remember the last good rate to use for subsequent requests.

It would perhaps be interesting to randomly generate content and hyperlinks to ever deeper random URLs -- are these new crawlers more interested in some URLs or extensions than others? If you pull fresh keywords from the full URL the crawler requested, will it delve ever deeper into that "topic"? If their Accept-Encoding header supports gzip or deflate, what happens when you feed them a zip-bomb?

Comment Re:Modern VR hardware is really disappointing (Score 1) 45

Streaming a game over the Internet is not comparable to streaming a game to a PC in the same room using a dedicated connection between a the headset and PC, where the antennas and radios on both sides are dedicated to the streaming video.

This is not something new. This is something that has been in widespread use for years, working quite well in existing headsets, like Oculus Air Link, Virtual Desktop, Steam Link, etc. The largest complaints about these solutions was often not latency, but image quality. This is what Valve aims to fix with foveated streaming, and all the hands-on coverage that we've seen so far indicates that it works extremely well. Valve is claiming 1-2ms of latency for a current-gen GPU, and 3-4ms of latency for an older GPU. Frames don't pass instantly over a DisplayPort cable either. You can't race the beam on a low-persistence display, you need to wait for the entire frame to transfer over.

Wireless is subject to interference, but 6 GHz is a very large and not widely used part of the spectrum, and interference doesn't cause a disconnection, it causes errors in the data or dropped packets. You don't wait for retransmissions, you just keep going and handle any missing or corrupted data through error correction or error resiliency. If a dropped packet causes a slight loss of detail in a small part of the frame for 1/120th of a second, you may not even notice.

This HMD doesn't work at all without steam. You need an account to use it.

Perhaps. But you are not limited to Steam games. If you're in the Steam garden, then there are no walls to that garden, and while you must start in the Steam garden, you are free to wander into other gardens.

This is absurd nonsense.

This is literally an advertised feature, one that was part of their hands-on demonstrations. Valve has contributed heavily to FEX (a user mode emulator, so you're not emulating system libraries), which is integrated with Proton in SteamOS. Yes, it's subject to any potential compatibility limitations, but I don't see how it's "absurd nonsense".

Comment Re:Guess I'll never own a GM. (Score 1) 218

Not all Android Automotive cars support Google applications (like Google Maps or the Play store), and not all Android apps are supported, so it's very much not like Android Auto in that respect. And having to manually enable tethering on your phone every time you get in the car (to avoid burning battery life) is hardly an ideal solution. Not to mention the inconvenience for iPhone users, who represent 55-60% of all smartphone users in North America, and aren't going to have the same set of apps they want to use or the same integration into the Google/Android ecosystem.

Android Automotive still has a limited number of supported apps (it doesn't support all Android apps), doesn't necessarily have access to Google apps or the Google play store (licensing Google Automotive Services to get access to Google apps is not required, and a bunch of car makers don't), doesn't automatically have the same apps/settings/accounts that your phone does, doesn't have your media library, doesn't use your existing cellular connection and data plan (unless you tether your phone or pay for a second data plan), and if you're an iPhone user (as 55-60% of people in North America are), then there's an even bigger disconnect.

Having to pay for a separate data plan should be a deal killer right off the bat.

Apple CarPlay and Android Auto allow your phone to take over the car's screens and speakers. If you're only playing music, then yes, a bluetooth connection is enough. But if you're using a map app with turn-by-turn directions (Google Maps, Waze, etc.) then you can see that app on the car's screen.

Turn-by-turn directions is also a good example of a service that's free with your phone, but subject to a subscription fees from many car makers that have their own built-in system.

I will not buy a car that does not have Apple CarPlay/Android Auto. Car systems always suck, and they don't have all the apps/accounts/settings/cellular connection/data plan that my phone does.

Literally the only reason that any car manufacturer tries to force you to use their own system is to sell you subscriptions.

Comment What cold winters? Iceland's not cold. (Score 1) 44

They cite "cold winters" as why mosquitos aren't found in Iceland, but... Iceland doesn't have cold winters. In Reykjavik, their lowest mean daily minimum temperature is -2 C in January. Here in Montreal, it's -14 C, so much colder, and there have always been mosquitos in Montreal.

I would imagine that Iceland's cold *summers* is probably more responsible. It never gets very warm, with a highest mean daily maximum of 15 C in July, versus Montreal at 27 C.

Comment Re:Jared Kushner (Score 1) 67

Kushner has been doing this kind of work in the Middle East since before Trump became President. Hell, before he even married into the family.

Bullshit. Citation needed. He dealt (poorly) in NYC real estate, just like his future father-in-law. From :

For much of his career, Kushner worked as a real-estate investor in New York City, especially through the family business Kushner Companies. He took over the company after his father, Charles Kushner, was convicted for 18 criminal charges

His "investment firm" was just a bribe for pulling the rug over Saudi Arabia's crown prince kidnapping, killing, and dismembering a journalist that was critical of him while Kushner was in the first Trump administration. Kushner never did any venture capital investing, but it didn't stop the Saudis from giving him billions of dollars.

From the same article:

Since leaving the White House, Kushner founded Affinity Partners, a private equity firm that derives most of its funds from the Saudi government's sovereign wealth fund.

So both of the buyers are the Saudi PIF, it's just one of them has a level of misdirection.

Comment Re:Too many EVs (Score 1) 120

So much so that utilities are forced to PAY out of state utilities to take our excess production.

I don't get this. It's solar. If you don't want the power then turn it off. The utility may not have that level of control over home inverters (though some do) but they certainly can control the output of any grid-scale solar install. Why would they be paying "out of state utilities" (presumably where the sun don't shine) to take the power? Utilities like money and that doesn't seem like a money-making idea. Yeah, they don't want their large capital investment sitting idle but it's better than running it and paying someone to take the output.
