I live in LA and Waymos are the only cars I don't have to play chicken with when crossing the street. Even the drivers that see you will just give you a "sorry, I'm in a rush" wave as they nearly run you over.
I did find the Waymos in SF disconcerting as they approached pedestrian crossings while I was waiting - with a human driver there's many different cues that they've seen you and noticed you - whether it be looking directly at you, or slowing down in preparation for you to cross.
I'm sure if I had just started walking across the crossing it would have reacted perfectly, but I wasn't willing - based on the lack of observable "I have noticed you" cues - to test that theory.
That combined with the parent's post is, perhaps counterintuitively, somewhat concerning.
The proper technique for yielding to pedestrians wishing to cross is to start slowing down early, as if you were planning to stop before the crossing. That sends a clear signal to the pedestrian they're good to start crossing. Then you're free to speed back up. This is very comfortable for the pedestrian and the vehicle never needs to stop, so the slowdown is minimal.
That Waymos apparently don't act this way and seem to need to send an explicit signal to pedestrians sounds concerning to me, even if its ultimately safe.
Waymo does slow down as it approaches stop signs (usually where crosswalks are) and it will slow down if there is a pedestrian entering the roadway (crosswalk or not) since it doesn't want to crash into them.
The explicit signal of a driver noticing you (eye contact) is replaced by the signal above the vehicle. Are you not equally concerned that pedestrians have to get an explicit signal from drivers who are legally required to yield or stop??
Ah, so this particular pedestrian crossing wasn't at a stop sign (we were at the big historic army place out by the Golden Gate bridge) so that might explain it.
Make sure to never be in a hurry to get anywhere because you might then get stuck behind a fleet of them going exactly the speed limit, grid locking you in.
In Italy several cities lowered the maximum speed from 50 to 30 km/h.
There was a huge fight over it, car drivers in those cities were mad. Plenty of politicians opposed it.
One year later stats were super clear: streets got way safer and the number of fatal accidents dropped to near 0. Time to traverse cities didn't change much, as it was already limited mostly by traffic and lights.
I think this ignores the argument the high speed limit people make which basically boils down to "sure some people will die or get injured but its worth it because driving faster is fun"
Autonomous vehicles following proper signalling before lane changes can be safe at arbitrary speeds (see Autobahns working at all). Humans, we should limit passing speed to roughly ~5 mph delta between adjacent lanes and leave it at that.
Humans with adequate following distance in the entire lane can probably manage 10 mph delta. I routinely travel dozens of miles very safely at ~80 with the flow of traffic (including the cops), and been stressed out at 55 in the carpool lane through stop and go traffic in the right-hand lanes due to on ramps/offramps.
I think 75 is memorable and roughly in the region where the tradeoff between increased kinetic energy and decreased time to arrival per additional unit of velocity becomes untenable.
Because American drivers have normalized always driving 10 mph (16 km/h) over the speed limit.
Cops won't pull you over or write tickets if you're not at least 15 mph over, we basically don't have speed cameras, everyone's trying to win the rat race and dehumanizing other cars around them, and it's not considered morally wrong (by most) to break that specific part of the law.
So a single vehicle obeying the law will quickly get a long line of tailgaters and tailgaters of tailgaters trying to "push" the vehicle to go faster.
They can suck it, I'm not late or in a hurry, and my ancient truck, steel bumper, and class 5 receiver hitch will not be badly harmed by your plastic grille. I get better gas mileage and have a longer stopping distance when I drive the limit, and I don't care if others are honking or riding my ass because they think I should drive faster.
> my ancient truck, steel bumper, and class 5 receiver hitch will not be badly harmed by your plastic grille
I've been rear-ended in my truck, and the receiver punched a nice hole right through the radiator of the guy who hit me. Definitely fucked his car up way more than it did my truck ... except man, that is definitely one of the hardest impacts I've ever felt in my body. I now appreciate how hard the head rests really are, despite looking a little soft. I think I'd rather have crumpled crumple zones and a new truck next time.
I've actually been involved in the commissioning of an FMVSS 202a headrest strength tester.
A lot of science and work goes into the construction of those headrests - if it was less firm, you'd get a concussion from the rotational forces in the whiplash or just break your neck, more firm and you'll get a concussion from the linear impact. It's not at all arbitrary, there's a reason they are exactly as firm as they are.
On most US highways (i.e. multi-lane limited access roads), it's customary to leave a path in the left 'passing lane' for any traffic that wants/needs to go faster than you. If cars match speeds across lanes, it impedes faster traffic.
The speed limit itself is a separate convention and regulation. In some places you can be cited for obstructing traffic by going the speed limit in the passing lane if you are matching the speed of cars to your right, effectively blocking the road.
> (b) An operator of a vehicle on a roadway moving more slowly than the normal speed of other vehicles at the time and place under the existing conditions shall drive in the right-hand lane available for vehicles, or as close as practicable to the
right-hand curb or edge of the roadway, unless the operator is:
> (1) passing another vehicle; or
> (2) preparing for a left turn at an intersection or into a private road or driveway.
Note this law specifically mentions "normal speed of other vehicles at the time and place" and doesn't directly mention speed limits. So by the text of this law, if you're driving the speed limit and hanging out in the left lane while the normal speed at that time is like 10 over you're technically breaking this law.
We have specific signage for highways where this is supposed to be the law.
Sometimes I an appreciate wanting to cruise in the middle lane, because ADAS level 2 systems common on cars today is far more comfortable when it does not have to deal with regular merging traffic. But aside from that, I really don't like it when people camp in the middle lane because they tend to form a pretty tight line and manage to effectively turn a three-lane highway into two single-lane highways -- hard to get through from one side to the other.
Sorry, I didn't fully explain the idiom: "centre lane" refers to the right-most (what in the US would be left-most) "fast" lane - the one closest to the centre of the highway as a whole.
To your point, I think the middle lane of a three-lane road is, ideally, the correct travel lane. Cruising there at the prevailing speed leaves one lane more lightly traveled for entering and exiting, and the other for passing. Predominantly using that lane minimizes lane changes, which are the most dangerous driving moments. You're right, though, that the strategy breaks down as traffic gets heavier, and gets ruined entirely when (as under discussion in this thread) people gum up the supposed "fast lane".
> If cars match speeds across lanes, it impedes faster traffic.
I think this undersells it a little. It does not just impede faster traffic, when the lanes are pacing each other it makes navigating harder -- simply switching lanes is more difficult. The highway moves so much more efficiently with a small but steady difference in speed between each lane.
> Results: A 5-mph increase in the maximum state speed limit was associated with an 8.5% increase in fatality rates on interstates/freeways and a 2.8% increase on other roads. In total during the 25-year study period, there were an estimated 36,760 more traffic fatalities than would have been expected if maximum speed limits had not increased—13,638 on interstates/freeways and 23,122 on other roads.
That doesn't make sense to me. If you want to change lanes, and worst case scenario you're right next to someone, go 2mph slower for 20 seconds and they'll be shifted by 60 feet. I'm sure you can plan your lane changes on a freeway 20 seconds in advance.
It is the dynamics. When lanes are pacing each other the gaps all tighten up. So sure, you can slow down a bit to find the gap behind you, except that gap is not big enough to fit in. So you turn on your signal and wait for someone polite enough to let you in, meanwhile the guy behind you is riding you like a pony because you are no longer keeping up with traffic.
When traffic isn't balled up so tight, you can plan for a lane change in advance and accomplish it without having to slow down traffic. Everything flows better.
> How do you get “stuck” behind someone doing the speed limit?
"Only 46.5 percent of U.S. drivers consider going more than 15 miles per hour over the speed limit on the freeway to be "extremely" or "very" dangerous — with 40.6 percent openly admitting to doing it at least "a few times" in the last 30 days" [1].
We have a lot of freeway speed limits that are holdovers from the last oil crisis decades ago. Cars have gotten quieter, smoother, more capable, to the point where 55 mph is kind of hilariously slow. When the legal speed limit does not reflect what most drivers think is reasonable, then we can stamp our feet and insist that the law must be right, or we could redesign the road or adjust the speed limit to more closely reflect conventional wisdom.
> we can stamp our feet and insist that the law must be right, or we could redesign the road or adjust the speed limit to more closely reflect conventional wisdom
Most Americans ignore speed limits. This stems from it being socially and legally problematic to permanently revoke our driver’s licenses. We should raise a lot of limits. But many others are fine and still sped through.
Where do you guys have 55 mph where it's not appropriate? A LLM is telling me that 55 mph is your random urban interstate. The equivalent where I live is 80 km/h on motorways inside city/town limits, which is 50 mph, and it feels very appropriate, cars make a ton of noise and you don't want the full motorway speed in the city. And that's basically the fastest you'll ever go in a city, when it's an actual motorway (often elevated, ramps, sound barriers). Other roads (even big and important) are ~43 mph and the general urban speed limit is ~31 mph.
> A LLM is telling me that 55 mph is your random urban interstate.
Yes, this sounds about right. In the metro area, 55 mph on a limited access interstate freeway. Arterial surface streets typically 40-45 mph, lower level surface streets commonly 25 mph and sometimes 20 mph depending on locality.
In the US, in particular out west where I live, 'urban' does not have the same meaning as it does somewhere much more dense, so it amounts to 55 mph in many places you might regard as rural.
On the stretch of motorway that I frequent in Italy, the speed limit is mostly 130 km/h, but the majority of people drive at about 100 to 110 km/h (including me).
But there are also people who drive in the left lane, who will tailgate you at 1 or 2 meters because you're doing 130 km/h. These people are idiots, but you get these sorts of people everywhere.
On American freeways, you don't have a choice, every lane is doing about 10 mph over the limit (or in LA way under) and it is disruptive or dangerous not to. These freeways tend to be running at full capacity so it actually makes sense since it improves capacity.
Road capacity does not increase with speed above 50 km/h on urban roads or 70 km/h on highways. Following distance scales with speed, so more speed can actually mean fewer cars per unit of time.
In theory, braking distance scales quadratically with speed. In practice, people leave less room on highways, because they rely on others driving predictably, but spacing still increases faster than linear.
I've been using it for 2.5 years at this point, and have the same experience. I don't think it's hopeless, but Kagi will need to step up their methods. IMO, there's actually a lot they can do here.
Copyleft is a mirror of copyright, not a way to fight copyright. It grants rights to the consumer where copyright grants rights to the creator. Importantly, it gives the end-user the right to modify the software running on their devices.
Unfortunately, there are cases where you simply can't just "re-implement" something. E.g., because doing so requires access to restricted tools, keys, or proprietary specifications.
"So, I looked for a way to stop that from happening. The method I came up with is called “copyleft.” It's called copyleft because it's sort of like taking copyright and flipping it over. [Laughter] Legally, copyleft works based on copyright. We use the existing copyright law, but we use it to achieve a very different goal."
"very different goal" isn't the same as "fundamentally destroying copyright"
the very different goal include to protect public code to stay public, be properly attributed, prevent companies from just "sizing" , motivate other to make their code public too etc.
and even if his goals where not like that, it wouldn't make a difference as this is what many people try to archive with using such licenses
this kind of AI usage is very much not in line with this goals,
and in general way cheaper to do software cloning isn't sufficient to fix many of the issues the FOSS movement tried to fix, especially not when looking at the current ecosystem most people are interacting with (i.e. Phones)
---
("sizing"): As in the typical MS embrace, extend and extinguish strategy of first embracing the code then giving it proprietary but available extensions/changes/bug fixes/security patches to then make them no longer available if you don't pay them/play by their rules.
---
Through in the end using AI as a "fancy complicated" photocopier for code is as much removing copyright as using a photocopier for code would. It doesn't matter if you use the photocopier blind folded and never looked at the thing you copied.
That’s not a rebuttal of the OP’s point. None of that says anything about fighting copyright. It literally says he flipped it which is wha the OP said when they said it’s a mirror.
To prevent malicious Wi-Fi clients from attacking other clients on the same network, vendors have introduced client isolation, a combination of mechanisms that block direct communication between clients. However, client isolation is not a standardized feature, making its security guarantees unclear. In this paper, we undertake a structured security analysis of Wi-Fi client isolation and uncover new classes of attacks that bypass this protection. We identify several root causes behind these weaknesses. First, Wi-Fi keys that protect broadcast frames are improperly managed and can be abused to bypass client isolation. Second, isolation is often only enforced at the MAC or IP layer, but not both. Third, weak synchronization of a client’s identity across the network stack allows one to bypass Wi-Fi client isolation at the network layer instead, enabling the interception of uplink and downlink traffic of other clients as well as internal backend devices. Every tested router and network was vulnerable to at least one attack. More broadly, the lack of standardization leads to inconsistent, ad hoc, and often incomplete implementations of isolation across vendors. Building on these insights, we design and evaluate end-toend attacks that enable full machine-in-the-middle capabilities in modern Wi-Fi networks. Although client isolation effectively mitigates legacy attacks like ARP spoofing, which has long been considered the only universal method for achieving machinein-the-middle positioning in local area networks, our attack introduces a general and practical alternative that restores this capability, even in the presence of client isolation.
Maybe I've just lost all patience for fluff, but I gave up trying to figure out what the attack was from the article pretty quickly where the abstract answered all my questions immediately.
The House of Lords is the most democratic hereditary system in the world. The 90 of the 92 heredities are elected from amongst the available candidates.
The house of lords is a stamping system at this point, and maybe a stopgap to authoritarianism. All power resides in the House of Commons which is elected
The true issue lies in the fact that the Westminster style of government is de facto an elective tyranny, with no real checks and balances other than the misused ECHR
If this were true, the papers wouldn't have run an article yesterday bitching about the lords sending back the workers rights bill again.
The commons may _eventually_ overrule them, but it takes time and costs political capital.
The majority of our population want more law, more rules, more restrictions : they don't see the value or enjoyment in doing something, so they don't think anyone should be able to do it.
Ask the average joe whether or not cars should prevent drivers from being able to "chose" to break the speed limit: You'll get a resounding "yes" 8/10 times - the value of freewill seems to be increasing lost on my country men.
I actually dont think your comment invalidates mine. The house of lords cannot really do anything than be a pain in the ass by sending the bill 3 times. The commons will eventually outrule them if they have sufficient political capital.
My comment on elective tyranny comes from the fact that if a trifecta of: leader/party mps/house of lords are aligned there is little to stop them.
This done I think all of the debates around authoritarianism and censorship put too much blame on the government which seems to represent the views of the majority of people rather well. I think it also comes from the fact that the median age is older and older people are more conservative in their choices and thus more willing to put limitations on everything (and also the fucking boomers vote as a 25% bloc which imposes their choices on the remaining poplation i.e the infamous triple lock of retirements)
We do need to provide better services, but that's not going to solve this issue. The vast majority of people struggling to make ends meet don't stoop to destroying public infrastructure. Only the true anti-social assholes go there.
This is the kind of attitude that gets us here. "Bad people don't deserve help or services. This is reserved for the morally pure." Or even more simply "Criminals don't deserve help. Lock em up and forget about em." We are still destroying lives over fucking weed. It's all connected.
This article left me more confused than enlightened. I recommend reading https://risencrypto.github.io/Monero/ instead as it actually explains how the cryptography fits into Monero.
You likely don't need to optimize anything; Emacs has seen some pretty significant optimizations recently (native Emacs Lisp compilation, tree-sitter modes, better handling of long lines, etc.) so performance is rarely the issue.
However, you do need to avoid call-process (spawning blocking processes) as much as possible. Also, my experience with TRAMP has been pretty awful due to the fix for https://debbugs.gnu.org/cgi/bugreport.cgi?bug=12145 (literally: TRAMP blocks all of Emacs while waiting on a network connection).
