That the numerical value of the resulting acceleration is greater upwards than downwards is likely due to friction. Uphill friction and gravity pull in the same direction, while downhill friction and gravity pull in opposite directions. You can use the difference in acceleration to estimate the friction. The average is the (projected) gravitational acceleration, from which you can calculate the inclination angle (assuming a constant slope)
How much my Android app costs?
I'll start with an example of how I calculate the pricing for my freelancing projects which perhaps would give you an idea on how it's done, and then I'll add a few points of advice I learned along the way.How much will this project cost me as a developer?Whenever I get hired to build a website or design something, I have to consider my expenses for the project first such as hosting, domain names, plugins, translation services, stock graphics/images, hired help, safety margin, etc. I calculate that amount and set it aside. Let's say that these expenses will come out at around $500.What is my labor worth?This depends on many factors such as your skills and experience, your quality of work, etc. One way I did it was to set a benchmark. Ideally, I wanted to be paid $150 per 4 hours of labor a day which gives me about $37.
5 per hour of labor.
How long do I need to work on this project?Is it a day? A week? A month? Whatever the timeline is, you have to consider how much your labor is worth. Let's say that my labor is worth $300 per day and I need 3 days of labor to finish this project. Therefore, I need about $900 for my labor.
Conclusion:In the example above, my expenses are $500, and my labor is $900. Therefore, I need to charge about $1,400. That's one way of doing it. It's worked well for me so far. Feel free to experiment and see what works for you. Keep in mind that this is only an example and not the actual amount. Every project is different.Advice:Good luck with your project and happy freelancing!
Give more weight to close-as-duplicate-votes from gold/silver tag badge carriers? duplicate
Time passes more slowly in low-view tag areas.Closing is a significant operation that without the intervention of a moderator does and should continue to require the cooperation of five different users with vote to close privilege. Changing the rules would allow many questions in high-view tag areas to be closed by only two users leading to a significant decrease in perception of community consensus.
Recent changes allow close votes not to expire too quickly in low-view tag areas. Give those changes time to work
What does the notice about personalized advice imply?
The purpose of this notice is to inform the visitors (especially new users joining the site) that we do not provide a personal advises. It is like a disclaimer. The decision of closing questions asking for personal advice as off-topic was taken long ago in 2015 See this answer. Consequently this off-topic reason is clarified at the on-topic page of the help center and set as one of the close reason while closing the question. So, it is not like we made the scope explicitly clear by this notice, it was already clear.If the question is clearly asking for personal advice then we should close it as off-topic straightforwardly that is to start casting of close votes immediately. Unlike our policy of deleting unsourced answers where we determined the time period, in this case we have never talked about any waiting period of time before initiating the process of closing the question. The procedure is to close questions asking for personal advice off-topic as soon as possible by close voting, nevertheless if OP wants to fix the question to fit into the scope of site, s/he can revise the question and closed questions are automatically drawn to re-open queue after revision so-that reviewers can look whether question deserves re-opening. As I've said first this notice has nothing to do with our procedure of closing off-topic questions. Notice is intended to work as a disclaimer for whoever visits or joins this site.
Why does everyone seem to think that moving clock appear to tick slower? duplicate
Both observers really do see the other set of clocks as ticking slow. But the thought experiment from Einstein doesn't contradict this.The key is that according to the person on the train the set of clocks along the track are not synchronized. They are only synchronized according to an observer standing on the ground, not for anyone in relative motion to the ground.An example:
If the person on the train looks at any individual clock they will see the clock ticking slowly as compared to their watch. Say there are two clocks anchored to the track A and B. At the moment the train passes clock A the rider's watch reads 0 sec, the time on clock A reads 0 sec and the time on clock B reads 10 sec (according to the rider; A and B are not synchronized in the rider's frame). Say $gamma2$ so, according to the train rider, clocks A and B tick at half the rate of their watch. The observer might take (according to their own watch) 2 seconds to reach clock B. At the moment they pass clock B it will read 11 sec (it is ticking half as fast as the watch). But the watch reads 2 sec. So even though the clocks A and B are ticking slowly clock B has "run ahead" of the watch when the train reaches B.
How do I start correctly in building database classes in c#?
INMO the idea to give up EF and other ORMs is not a very good one if you are intending to produce a professional production application today that will be used as part of a larger project. This was viable option in the early days of .NET.The advantages of using EF/ORM are so many and if you program for living, you will probably have to learn about it anyway, so do it now if you can.
Datasets are easier to use and program with but some people hate them. If you are not strong in OO, datasets will help you go quicker but this approach is usually criticized.Connection to the database should be centralized and hidden from client code. It is common to use the Factory pattern to create objects. You start a transaction by establishing a connection and then close it. Closing a connection in code does not always physically close the connection, instead it returns it the pool of available connections. So yes, you issue close implicitly or explicitly in your methods code.I would like to recommend to you to spend some time with a book that takes an application from start to end to see your questions answered in more details. There are several concepts that you need to be aware of to get your application performing well and secure. Also, differentiate between training projects and production projects. Web development is not trivial and it takes sometime to learn and master
