Wow, I'm very happy to see lively conversation. I haven't really expected anyone to be interested, so I've tried to simplify and offer the simple advice at the end. To provide some background, I've spend several years organizing racetrack events, riding schools, sale event that included closed circuit demonstration and took part in organizing some emergency services driving courses. This included hypermiling competitions and test drives as part of vehicle development. In case of both diesel and gasoline powered vehicles, the best results were always achieved by the technique described in OP. Perhaps the most significant effect can be observed in motorcycles, which was also my primary domain. As to explain why I care, we would get clients that would feather the throttle, thinking they are being efficient and helping the engine. They would do this in situations like turning onto a main road or merging on a motorway, where reaching the speed of other traffic and avoiding a rear end is paramount and there is an outsized vulnerability of motorcyclists. One such accident happened to a client riding to our event. Luckily, there were no long term injuries, but it is the main reason, why I'm invested in this topic. As for automatic transmission and hybrid vehicles, I've never observed them in a hypermiling exercise, but would certainly be interested in exploring optimization techniques, especially comparing the ECO mode to manual modes and switching between EV, battery recharge, gas only and combined modes! As for the engines themselves, while there is a lot of variation, there are also a lot of physical effects, that will always be present, if you want to provide the efficiencies that current ICE engines achieve. You need to deliver the fuel to the combustion chamber with minimal drag, you need to mix it with air before the compression cycle is finished, with gas engine, you need to assure that the ignition spreads evenly through the chamber, you need to maintain the pressure on the piston throughout the cycle (this is why oversquare engine can't achieve high RPM, the piston would move too fast for the gas expansion to maintain pressure). This is why engine load, not the RPM is the main thing to watch. If the torque is the rotational power of the crankshaft the engine load is the force that acts to stop this rotational movement. If the load exceeds the torque, the engine stalls. If the manufacturer targets a specific power and torque at a displacement, they need to optimize the effect from previous paragraph at the load, where these values can be achieved. That is why I've never seen a modern (2000+) car, van or motorcycle engine, that would have peak efficiency under 60% load. More sophisticated injection, variable valve timing and the switch from fuel maps to using real-time input from the various sensors could most likely widen this efficiency window and complicate the results, again, something I'd love to discuss. While there is a maximal torque reached at a specific RPM, the drag force acting against the movement of piston relative to the cylinder is the main factor of efficiency when RPMs are concerned, because the drag force grows with the square of the relative speed, there are RPMs that will never be efficient, so the relevance of peak torque is very much engine dependent, with some high torque undersquare engines with small cylinders having awful efficiency at peak torque.

In WAN show on 12th April at around 3rd hour, Linus and Luke talk about light acceleration being more efficient than stronger acceleration. This is a very common misconception, that I've encountered way to often, when working in this field. Engines work optimally at optimal load, which, for ICE engines, is close to full load. For electric motors, it varies greatly based on design. For optimal efficiency and best fuel mileage, you'd want to accelerate at near full load in highest gear, until reaching the revs where the friction of the piston against the the cylinder causes too much drag and a speed where the wind resistance causes too much drag. In fuel mileage competitions, when a driver reaches this speed, they shut off the gas and let the kinetic energy turn the engine, or they just switch the engine off and shift into neutral, if they can save more fuel than what it takes to start the engine. I'm not saying anybody outside a competition should drive like this, that would be horrible, but don't feather that gas pedal either. Keeping the engine at minimal load all the time won't help it and you are not winning on efficiency either.

It would be very nice to have a written version of this video. This was a very nice compilation of quite a lot of useful advice.

WTF India? You are supposed to be the biggest democracy in the world, not the second biggest totalitarian regime.

I don't understand, if it has coreboot, why couldn't you boot into Linux for comparison? The video went over this part very quickly, so I didn't really understand. From searching, it seems that crostini is just a virtualization layer that allows some *nix container to interact with the hardware. Since chrome os uses Linux kernel, accessing hw shouldn't be difficult, so why use crostini, why not just boot into Linux? (I don't know much about chromebooks, I just want to know).

Wow, what an episode, the 3 top stories and I've missed all off them and all off them really bad news. Kinda glad I found out on weekend, time for some angry news reading, thank you for the sources .

Thanks, it's really nice to see a reaction directly from a producer and even with a full explanation, now it makes a perfect sense and thanks for caring about quality of the content. News agencies could learn a lot from you. While it's nice to have review for cameras in the $100-600USD range, these videos are useful as well. First of all, there are some pretty loaded people who will buy it just because they like the texture of the grip or whatever, then there are semi-pro photographers who are maybe not so much into the scene, but they've found success within their niche and need to upgrade fast. Many of us are employed at companies with marketing departments, documentation departments etc., those will have a camera like this and incidentally, they probably wouldn't have even bought lenses for it or made sure their glass is compatible, so it's nice to be at least a little familiar with the camera, if you are going to borrow it. And lastly, these do go down in price on a second hand market, so they'd eventually be in a price range of non-photographers.

Ah I see, that is likely it. It would be great if LTT informed on these situations, but it's great that there is a attentive community and a place to discuss this, thanks .

I've wanted to go back to a nice review of Nikon Z9 from Brandon, but it has been switched to private. It was not all that positive, but seemed fair and had a lot of information, what has happened to it? Why was it pulled? It was a breath of fresh air to actually hear some constructive criticism in a review, it's really helpful to know about things that might not work well in a class of device, so that you know what to look out for.

There was a sponsor that offered hosted VMs, pretty much like linode, but cheaper. I thing they had 2GB RAM + 40GB storage for less than linode basic tear. Which company was that?

Darn, going from an OK title "This Cheap CPU is REALLY Expensive!" to a really silly one "How is this even possible?". That's the opposite of the promised switch to more sensible titles one the video has it's initial surge. I wanted to watch it and wouldn't have found it, if forum didn't keep the better title.

I love that you are doing factory tours again. I realize that this might have been a limitation imposed upon you, but the structure if the video didn't really take advantage of the fact that you were on location. You were in one spot, talked a bit, then cut to another place. It didn't literary take us through the process and you didn't point things out, just talked about them. If that wasn't a choice of direction, but requirement from the company, please disregard this feedback .

Thank you for the additional information, this does make it better. I whish they'd put it in the description, annotation, OP of this thread, anywhere. I just don't know how to discern the entertainment content from the informative content, the high effort from the improv ones. There are some extremely informative and educational videos from LTT that I have learn a ton from, just as there are some videos that are so interesting and you just see the days and weeks that went into them, but then there are some barely scripted that stretch a 2minute idea into 12 minute almost reminding me of a video blog, but with a high production values. I'm looking forward to the full review, the big-little architecture is quite intriguing.

I have watched a video where you have proclaimed your commitment to in depth reviews, building new facilities, expert hardware analysis and then I watch this video, that I have at first missed because of the non-descriptive title and instead of providing useful information, you've compared the new CPUs on a yet unrefined OS with low adoption rate and wildly inconsistent performance and used different RAM with wildly different clock rates. Sure, it produces interesting number and makes for an entertaining narrative, but if you are an entertainment channel, just say so, don't make statements about you journalistic commitment, taking the flag from traditional tech media. If you were after informative content, why couldn't you also use the same DDR4 in the 12th gen chips for at least few tests? Why couldn't you run at least a few test on W10, 2k19, Debian and RHEL? All of them much more mature platforms. That would have been genuinely informative content. Why should anyone trust that you will surpass the tech press with state of the art facilities and commitment when here, you could have made an informative content with no additional HW requirements, just additional effort and man-hours and you chose not to?

I love that you still include detailed sources. When WAN show stopped including them, it kind of killed it for me. Also, why is Riley always on the green-screen set?

This is one of the coolest videos you have done and I almost didn't click it because of the terrible title. Fortunately, it popped up in search results. I mean, you even went back to the video, according to metadata, you came back and added subtitles (which is great, it makes the video easily searchable), why not add at least "PTP" or "precise synchrnonization" to the title? Ahmad and Alex, as well as the rest of the team, had made a great job explaining this, I've learned a lot and am glad to have found the video, but many more wont. I assume there is some reason why you don't just prepare more descriptive title and set like a 3 day reminder to change it, once the views have already spiked, I just can't fathom what it could be.

I think that this video has been out for long enough, that you could put the name of the laptop and more importantly, the company, in the title. I really thing they need to put their name out there, so having it right in the title would be very helpful and would be a great help when navigating the search results.

Yes, these would be great in a home server, so it'd be great if you could fill in their power consumption at idle and under load, compared to Ryzen and also elaborate more on the available MOBOs and the PCI-e expansion they offer at different price-points, since if I have to spend extra in order to utilize the extra, although slower, PCI lanes and then spend more money running it, it might be quite a bad deal...

I've often been wondering, why are the PCI expansion cards that allow access to the disks individually so much more expensive that the ones that offer HW raid? I understand that these HBA controllers that offer a lot of sharing of capacity and crazy expansion with expander modules are pricey, buy if I just want a simple pass-through and don't care much about latency or speed, is there some option for that?

Why does LTT have a cool studio full of cool and talented people, yet every video it's just Linus at his house, usually with a static or a handy cam either doing little prepared unscripted video that takes twice as long as necessary, or one like this, where he just reads a script someone else wrote, which could have just as well been done by a robot. We are well into month 2 of the two weeks isolation based on symptoms that seem to be based on a marketing decision, rather than reality, since they've never really materialized and this whole thing couldn't feel any more phony.

I was hoping they would compare it against the original passive cooler when it gets a decent airflow, like it might in your standard system. Nothing against the worst case scenario, but with that as the only representation, the information value of the video is somewhat diminished.

TechCrunch is well known and reputable news source. And the news absolutely is tech, it deals with use of recently discovered exploit and it's use to extrapolate personal and logistical data from mobile phones. The malicious code on the infected websites, which might have been added without the site owner knowledge or consent, was indeed targeting any device, but the attack vectors were critically different. The point of breach used for iOS devices used watering hole 0 day attack that required no further interaction from the user apart from visiting the website. Such an attack is extremely dangerous, as it is hard to do due diligence if you can't even apprise the website safely. The Android and Windows attack vectors focus on known penetration practices and require the user to take further actions upon visiting the website in order to gain unauthorized access. I'd also like to point out how well the community handled this incident. Project Zero worked with FBI on blocking access and with Apple to quickly implement the fix, the whole situation was professionally handled and only then published. These vulnerabilities are unfortunate, but the impact could be mitigated with professional approach and proper communication, both within the industry and by communication with the wider userbase (something I'm trying to help with, at least a little ).

True, but I think it's still important to report on it, both to make sure we don't forget about their plight, but also to make sure we don't go down the same way. It's crazy that I still do know people that think China is a great country we should learn from.

The recentl iPhone exploit discovered by Project Zero has apparently been utilized for more than two years by the chinese government to spy on its Uyghur population living in the Xinjiang province. Original exploit disclosure China backed group behind many of the incidents

David is really good and talented as the "product interaction model", that element was missing after Maxine left, I'm really happy that David has managed to fill that role. Funny that they are both camera operators, I guess that makes them aware of what looks good on camera.
