    1. Theimpact on congestiondeserves further study. A significant portion of traffic in some cities, such as San Francisco and Los Angeles, is attributable to drivers searching for parking (Winston, 2013). Ridesharing means that people who use ridesharing instead of driving no longer need to search for these spaces, which could reduce congestion.Furthermore, there may be a reduction in congestion costs associated with taxis finding customers (to the extent that ridesharing substitutes for traditional taxi services).The overall impact on congestion is notclear, however,because more consumers will be making use of these services.Some consumers, for example, may switch from mass transit to ridesharing if they are perceived as substitutes. This shift could actually increase congestion

      shows how most traffic is because of people trying to find parking, while if using a ride sharing service there is no need for parking therefore congestion decreases.

    2. Ridesharing platforms canhave several economic benefits.7These platformsincrease the transportation options available to consumers and businessesand are therefore likely to significantly increase consumer welfare. Lyft andUbergivethe consumer multiple different types of rides to choose from.For example, riderscantypicallyrequest a normal car and ride from a partner driver, carpooling at a cheaper price,a ride in a large car,ora luxury car.8These ridesharing platforms may alsoencourage higher utilization of the existing vehicle stock. One study,performed in five cities, found that Uber drivers had higher capacity utilization rates than taxis, likely due to Uber’s more efficient ordering and pricing methods, its larger scale, as well as inefficiencies of taxi regulation (Cramer and Krueger, 2016).Some cities have allocateddedicated parking spots throughout the city to such ridesharing under the assumption that they may generate social benefits (Shaheen, 2010).

      Advantages for ride sharing platforms for the economy with case studies and primary research.

    3. 4trust in exchange, which makes use of buyerand seller ratings. They afford sellers (i.e., drivers) flexibility in when they choose to work.6Riders do not spend time paying for a ride because payment is done automatically with a credit cardwhen the ride is over. In addition, many ridesharing platforms have a transparent way of adjusting prices to balance supply and demandand thus promote economic efficiency(Hall and Nosko, 2015)

      Advantages on how technology makes the proces easier and more efficient

    4. hese platforms take advantage of GPS to arrange for the ride and help determine a driver’s best route. They also provide other benefits for riders and drivers, including measures of rider and driver quality to foster trust(Luca, 2016), and an efficient payment system, frequently using a credit card that is entered into the platform’s data base. The platforms also can help balance demand and supply by adjusting prices in real time to accommodate shortfalls in the supply of drivers or surges in demand.

      HUge advantages for consumers and participants

    5. Typically, a customer uses an app on her smartphone to request a ride at a particular timeand place

      This is one of the main reasesons for the success of the sharing economy, where you get a car at the place you want after a touch of a button.

    6. Ridesharing platforms connect drivers and vehicles with consumers who want ridesat an agreed price.

      thats one of the main advantages to consumers, on the other hand if they take a normal cab they have no clue what they are going to pay

    1. Replication is important for two primary reasons:
      • HA with fail-over mechanism.
      • scale out your search volume/throughput as searches can happen based on your replicas in parallel.
    2. Sharding is important for two primary reasons:
      • horizontal scaling of a single index
      • parallelize seek operations on multiple shards when index gets too big

    1. Smalltalk doesn’t have to be pragmatic, because it’s better than its imitators and the things that make it different are also the things that give it an advantage.

    1. Below I list a few advantages and drawbacks of anonymity where I assume that a drawback of anonymous review is an advantage of identified review and vice versa. Drawbacks Reviewers do not get credit for their work. They cannot, for example, reference particular reviews in their CVs as they can with publications. It is relatively “easy” for a reviewer to provide unnecessarily blunt or harsh critique. It is difficult to guess if the reviewer has any conflict of interest with the authors by being, for example, a competing researcher interested in stalling the paper’s publication. Advantages Reviewers do not have to fear “payback” for an unfavourable review that is perceived as unfair by the authors of the work. Some (perhaps especially “high-profile” senior faculty members) reviewers might find it difficult to find the time to provide as thorough a review as they would ideally like to, yet would still like to contribute and can perhaps provide valuable experienced insight. They can do so without putting their reputation on the line.
    1. With most journals, if I submit a paper that is rejected, that information is private and I can re-submit elsewhere. In open review, with a negative review one can publicly lose face as well as lose the possibility of re-submitting the paper. Won’t this be a significant disincentive to submit? This is precisely what we are trying to change. Currently, scientists can submit a paper numerous times, receive numerous negative reviews and ultimately publish their paper somewhere else after having “passed” peer review. If scientists prefer this system then science is in a dangerous place. By choosing this model, we as scientists are basically saying we prefer nice neat stories that no one will criticize. This is silly though because science, more often than not, is not neat and perfect. The Winnower believes that transparency in publishing is of the utmost importance. Going from a closed anonymous system to an open system will be hard for many scientists but I believe that it is the right thing to do if we care about the truth.

    1. Manhas,asitwere,becomea kind of prosthetic God. When he puts on all his auxiliary organs he is truly magnificent.

      So... our inventions (technology) and how we implement them throughout society can make us god like? Makes me think of how we acquire different skill sets so that we can adapt to different tasks or work responsibilities (wearing different hats - if anyone has heard that metaphor)
