I’m a kind of loner, so whether people recognize me or not doesn’t really matter to me.” I kind of liked it it’s good to be anonymous. “They kept saying, ‘Who are you?'” says Tucker, who starred in ’97’s “Money Talks.” Tucker – whose screeching, rapid-fire delivery and elastic-limbed mania were introduced to a wide audience in a supporting role in 1997’s “The Fifth Element” – actually enjoyed being incognito. ![]() “I was Tito,” he adds, referring to a line from “Rush Hour 2.” “They love him there! He’s like Michael Jackson over there.” “Jackie took me shopping, to his restaurant, to his clothing stores – it was fun to see how different the culture is in Hong Kong,” he says. Tucker says he was blown away by just how beloved the 47-year-old Chan is in Asia. It was so funny, and we really put those things in this movie.” “I remember we do, three years ago, a promotional tour and Chris got really lost in Hong Kong. “Chris was always saying, ‘Oh Jackie, you’re the king, you’re the king!’ “I was so happy doing a film in Hong Kong,” he says. In the sequel, Carter becomes the fish out of water, arriving for a vacation in Hong Kong armed with his Chinese-English dictionary, only to be reluctantly caught up in Lee’s investigation into a money-smuggling ring.Ĭhan, the leading box-office draw in Asia, with more than 100 films to his credit, delighted in introducing Tucker to his hometown. “Rush Hour 2,” out Friday, continues the culture-clash hijinks of the first film, in which Chan’s Hong Kong detective Chief Inspector Lee traveled to Los Angeles and was paired with Tucker’s LAPD officer James Carter. He was getting $5 million for a picture, and I would say, ‘Wow, $5 million! I’m a big star in Asia and I only get half a million!'” “I remember, 15 years ago, Burt Reynolds was the highest-paid actor in the world. “I make movies for 40 years and he’s been scratching along himself for so many years,” he says. It all just came into place.”Ĭhan – who recalls being paid $220 for his first movie – stresses that neither he nor Tucker is an overnight success. I almost dreamed it already, so when this stuff happened, I wasn’t surprised. ![]() ![]() “I think it’s part of what the business is. “The talk about money doesn’t bother me, not really,” Tucker says. I like to do a little gambling – it makes me do the film better.”Īll this focus on salaries may seem a little crass, but the number of zeroes on an actor’s paycheck has become the gauge of success in Hollywood. “So I chose $15 million plus rather than $20 million. “I trust that part two will make at least as much as the first one,” Chan says. But while Tucker chose to take $20 million up front, Chan gambled. “‘Rush Hour’ was a big success, so you benefit from that success.”Ĭhan, the other half of filmdom’s most hyperkinetic duo, was also paid handsomely for this fresh installment of what looks to become a killer franchise. “ made $250 million around the world, so $20 million isn’t that much when you look at it like that,” he told The Post.

Less than 10 years ago, Chris Tucker was an unknown comic honing his manic shtick at L.A. ![]() ![]() I think it's complete crap our pay solely relies on a customers tip. Some customers take complete advantage of us and ask for too much and we do it with good customer service for that $2 dollar or no tip pay. In the customers eyes we are the representation of the company we have to look happy and respectful when we deliver to the customers. I don't think it's right on many levels, their are hardworking dashers getting played like this and accepting such terrible pay. You are so right, we make this company possible. I have been picking up on these changes, and it makes me livid. I'm sorry that disrupted your bicycle game. Thank you for your feeback, I greatly appreciate you! I just can't accept those 5$ or less orders to get their. I can't cherry pick anymore, and I have been tempted to see if I bring up my acceptance rate to 70% things may go slightly better. I'll expect a knock at my door from men in suits with a big red D on their chest playing the Godfather theme for me even bringing it up. Side note- the video of Xu stuttering for like a minute straight when asked about the $3 orders on YouTube went poof! I looked everywhere! Under my chair, under my keyboard, in my bag of doritos, I can't find it! Where did it go? I wonder □. I have medical issues and have little choice. Yes you are 100% being played and if you don't need to be here you need to move on. If you go into dash utility and select "speak to me" when they play "quiet time" it still won't make a sound. They coded it that way, it was no accident. They want to kick off people who are idle, or who are using dash utility to be idle indefinitely. With the recession and immigrant crisis the timing couldn't have been better.Īlso the "quiet game" they've been playing lately where the orders don't make a sound, but will if you don't hit accept or decline. They're losing respect for the delivery apps by the day. The restaurants aren't going to go any faster. How do you get orders done quicker? Knock out the cherry pickers wasting your time in queue. It rains $10 coupons and everyone posts negative earnings every quarter. Prices? That results in a tie between them and UE. So how do you compete if you're DD? Driver quality? People don't care much if most pick leave it at door. ![]() They didn't need to compete because they were already #1 but they did. We need be paid more as dashers, I can't dash for that pay I'm sorry.ĭo other dashers feel like they are getting played by this app too, or is time just me?! We are "independent contractors" you should not be penalized for not accepting a $2-$5 order that is not worth your time and gas. It doesn't make any sense to me how Doordash says to raise your Acceptance Rate to 50% to be prioritized for high acceptance orders, and that rarely never happens. *Their are alot of dashers in my market, so I wonder of this impacts everything. I know the amount of money you make as a dasher depends on the market that you are in, but wow I'm in a pretty decent market and only "some" days are eh.okay with a 50% Acceptance Rate, and some days are just as bad as when I had a 20% acceptance rate. ![]() Your just slightly lucky if they are stacked, because most of the time it still ends up terrible pay in the end.□ *Like 2$-4$ orders on average for example. "slightly" you still get a ton of really terrible offers that are not worth your time and money. ![]() I've also noticed if you keep it up in the 50% range things just go a little better for you. I've let my acceptance rate go down to 20%, door dash will literally pause your orders if you decline too much and put you on pause, further wasting your time and money. ![]() ![]() This can be particularly true if a user experienced any errors during the original installation process.

ReactOS, like many other FOSS alt OSes (such as Haiku) is not going to be very useful for serious gaming or even audio works, as most vendors now only make drivers for Win10 (or maybe Win7 and macOS if the respective userbases are large enough). However that goal changed since 0.4.x as they're targeting NT 5.2 (XP/2003) now. Originally ReactOS 0.3.x targeted NT 4.0 API level. Probably they should look into the leaked Microsoft stuffs and create something inspired by it which may make their work significantly faster. ![]() Some popular office applications and media applications worked fine though. The last time I tried, it wasn't able to run MIDI. It slowly is trying to reach there, but that's a long path ahead. ReactOS aims to be 100% compatible with Windows, doesn't it? Is it planned to have any advantages over Windows (other than presumably ReactOS being free to the end user), such as running faster, or better compatibility options for backwards compatibility? I am saying this because this has been done cleverly but I am none to decide what projects choose to do. It is stranger you can just get pieces of code on a direct google search leading you to the whole thing. In the current day, you dont have to keep a copy of the code to save yourself from an FBI raid. And even if you look at the source, it is as rare as a camellia japonica that you get something copied.

Back when they were calling Linux a cancer and actively spreading FUD about open-source software. Certainly there was a time when they would have. Whether the Microsoft of today would sue I have no idea. The last thing the project needs is Microsoft accusing them of using stolen code. If they don't want to have the project shut down playing by the rules is very important. And Microsoft has an awful lot of money to spend on lawyers to stop such a thing from ever happening. The problem here is Microsoft probably won't really appreciate a compatible windows clone that people could just use for free instead of paying for real Windows. Microsoft didn't give permission for it to be out there so no one has a license that permits them to have it. Simply having a copy of the leaked code is very much illegal. Of course I shouldn't be discussing but it's just what I felt. This won't be copying and I don't see why it should be illegal. ![]() Probably they have lessons to learn and have similar things to implement. They won't last a week with their product if they use. You will be blocked/banned from their social media and forums if you so much as suggest the idea or try to discuss it.Īs for gaming, it's making great progress in that area, but it's currently intended more for the 98/XP Direct3D games than the 3.1/95 ones that people here would play.ĭevs don't have to use their code either.

![]() It is called the Proton Pyrophosphatase Pump. There is one pump that isn't as strong, and so acts a little out of the ordinary. Pumping against a gradient can be difficult, so the job of proton pumps is hard work. We also have these ions moving uphill, into areas of higher concentration, using a proton pump. So far, we have hydrogen ions moving downhill through transporters and releasing energy. So, when concentrations of hydrogen ions are high, the plant can move more sugar into plant tissues. Plants can also strap a sugar molecule to a hydrogen ion to be carried across a membrane. If plants did not do this, there would eventually be no more concentration gradient to release energy, and the plant would die. Yet this work gives many benefits to the organisms, including plants. In a cell, using energy to move ions uphill when there are already lots of ions there seems a bit odd. Diffusion can then use this gradient to capture energy again, as the ions move downhill. Ions moving down a gradient release energy, but when they move up a gradient, it takes energy. In cells, it is very similar. Proton pumps are a special kind of transporter that push hydrogen ions from areas of low concentration to areas with high concentration. When water or ions move down through a concentration gradient, energy can be used or stored. But when that water level (or concentration gradient) is kept high, more energy is stored that can be used for other things. To move water up the concentration gradient can take a lot of energy. Wind power plays a leading role in driving demand growth due to a. In the dam, this is like when pumps are used to keep the water level in a reservoir behind the dam high. In this report, aluminium demand is assessed for electricity networks only and is not. ![]() This is how concentration gradients are maintained. ![]() However, hydrogen ions can also be moved the other way, toward areas of high concentration. This energy can be used to take a molecule from inside the cell and move it out or can help make ATP in a specialized enzyme. When a hydrogen ion passes down the concentration gradient through a transporter, it makes that potential energy available. In the same way, cell membranes keep the concentration gradient of hydrogen high. If water is let through a spillway or floodgate, it can spin a turbine and create energy. As water builds up on one side of the dam, the concentration gradient is high and has lots of potential energy. If we think of a cell membrane as a dam, we can get a better idea of how the transporters in membranes work. A cell membrane can be thought of as a dam. ![]() |
