What you’re describing is called “rollback netcode”. It’s a pretty cool chunk of theory, usually used for fighting games which are extremely sensitive to latency. This explainer has some nice graphic demos
It's a common misconception that this is only used in fighting games. This technique was developed first in Duke Nukem, and then exploited heavily by Carmack in Quake, and subsequently refined and built upon in other AAA FPS games, specifically for the local player movement and shooting.
I don't think it's quite the same. Rollback netcode is like lockstep netcode, where the entire game is simulated locally and only inputs are networked. Since it's still only input being networked, network drops (or slow computers) affect everyone, requiring the simulation to slow down. Not just fighting games, but RTS games would do this. If you've ever played Starcraft/Warcraft 3 where it would freeze when a player disconnected.
With rollback/lockstep, there's no need for a server simulation at all. Most games are not doing that: the client's local simulations are less important than the server's simulation, even missing information (good to prevent wallhacks). Any dropped packets are handled with the server telling the client the exact positions of everything, leading to warping. Dropped packets and latency also only affect the problem player, rather than pausing everyone's simulations.
This is awesome and exactly what it needs, but good luck creating a language that’s “signal driven” enough to encode it and then send all the possible states to the client.
If you were able to make it, it would be kind of a Hail Mary moment for making easy server games without the latency.
I wonder if there was an aspect to it where the scam was so audacious that they figured it wasn’t a scam. Like a “there’s no way they would generate millions of fake users which would obviously get caught post-acquisition, we must be missing something”
It doesn’t have to be the case that everyone who supports age verification has the same reasons.
In the US however, this campaign came from the same think tanks and strategists associated with Project 2025 (taking cues from folks like Enough Is Enough), who are pretty upfront with their Christian Nationalist views. In Project 2025 they include a bizarre connection of porn with transgenderism that tips their hand on the religious bent to all this, but elsewhere in the plan outright state their Christian Nationalist ideals.
This is probably the main one. I could completely understand wanting the assistance of a loved one for mundane things like standing up.
Although to your “not prepped for MRI” point, it is kind of wild that someone with a 20 lbs chain around their neck would be allowed even on the same floor as a MRI machine. Although last time I saw one in person, the door to the room did have some pretty blunt warning text in large print.
Last time I went to an MRI, there was a prep room before the MRI machine. There was a stern and visible warning to remove anything metallic from your body before going through the second door. I am fully aware if the pins on my leg were affected, the machine would gladly remove them from my, most likely along with the bone and the leg they are attached to.
A lot of fatal accidents are like that - a series of small mistakes nobody notices, each individually harmless, followed by THAT ONE BIG MISTAKE that ends up killing someone (or a lot of people).
I'm not sure what "engineering control" means. Just put it in front of the door to the MRI room. Alarm goes off, you do not get to enter, it should be as simple as that.
An engineering control is how your microwave works—if the door isn’t physically closed, it can’t run. The way many (most?) hospitals currently operate is called an administrative control—analogous to a sign on the microwave door telling people not to run the microwave with the door open or open the door when the microwave is on.
But MRI machines can't be turned on and shut off that easily. As someone here explained, it takes up to 15 minutes for the magnet in an MRI to "shut down", and costs $50,000 each time.
Why not just control access to the room behind a metal detector? It would be really simple, but effective. I don't think any MRI should be allowed to operate without this basic level of protection.
Sure, an engineering control for MRI room access would be implemented differently--that's just the canonical example that people are familiar with. One possible implementation for MRI access is the airlock method, where the inner access door would only be allowed to unlock with the outer door locked and no metal detected in the space between (also the outer door would be prohibited from unlocking when the inner door is unlocked, except for some kind of inner emergency override that might also be tied to the emergency quench).
Literally no one disagrees with you on this, and most (if not all) hospital administrators will say they already do it the way you suggest. I'm pointing out that the actual implementations I'm aware of are often ineffective because they use administrative rather than engineering controls, and this is a critical distinction people need to be more aware of when interacting with dangerous systems. Managers, at least in my experience, tend to wildly overestimate compliance rates with administrative controls, even ignoring any possibility of deliberate noncompliance.
Let’s say summer break is basically 3 months. I as a parent need to figure out childcare for that 3 month period at the beginning of summer. This is a much more time consuming endeavor than most would expect (or at least more than I expected). If you distribute those months throughout the year I need to repeat this process 3 different times, adding a bunch of overhead that could be spent on activities more beneficial to my family and kids.
Edit: Adding that I realize the summer slowdown absolutely exists and has a disproportionate effect on those that don’t need another wrench thrown in their life. But just wanted to add a perspective that isn’t “teacher union boogeyman”.
If I’m remembering correctly, Conficker was the first major use of this technique. They used a relatively small domain pool (250) so the registries were able to lock them up preemptively.
I remember a couple legitimate sites getting slammed by accidental DDOS because the algorithm happened to generate their domain, but having a hard time finding a reference to that.
I feel the same way. If Signal supported bots/an API and “Communities” (in the WhatsApp sense) I’d finally be able to cutover all my use-cases from Discord. I get that the E2EE is a bit tricky for an API, and that you can kind of hack together Communities by just having a couple group chats, but the UX gap is just a little too big
The congressional decision was to scrap the continued development of the DMSP satellites, not to decommission the existing ones or stop the data sharing arrangement. The DoD confirmed the DMSP is still operating and will continue to do so but the data sharing is what they have now decided to cut off.
It also looks like one of the “next-generation” systems, the JPSS, has been ordered to operate in maintenance mode.
AFAIK, Congress voted in 2015 to terminate the whole DMSP program. There was no mention of continuation of "data sharing" or anything like that, as you suggest. I guess in the DOGE budget cleanup of DoD, terminated programs are really being terminated instead of continuing to operate under the radar.
Regarding JPSS - that article says that new JPSS satellites are scheduled to be launched. I agree that the "minimum mission operations approach" doesn't make much sense if that is the case. My guess is that this is a stupid cost cutting move that will most likely be rolled back after pushback.
If you pirate a book on software engineering and then use that knowledge to start a career, do you owe the author the royalties they would be paid had you bought the book?
If the career you start isn't software engineering directly but instead re-teaching the information you learned from that book to millions of paying students, is the regular royalty payment for the book still fair?
