    Understanding a rudimentary solution to Critical Section Problem

    (Source: page 20 of this :http://www.ics.uci.edu/~bic/courses/JaverOS/ch2.pdf) The part I put in bold looks like nonsense. Since program1 executes after the Critical Section and after turn gets set to 2, there is nothing stopping p2 from leaving its wait loop and entering its critical...

    Explain the mechanics behind this bizarre video

    This building gets pulled down and in a weird unexpected kind of blast everything shoots out sideways. The guy holding the camera gets knocked out and the camera is just lying on the floor but there's nothing graphic in the video. My mind is blown trying to understand what happened and how...

    AT commands, datacall, hyperterminal

    Nor sure if this is the right subforum for this question. I think it will reach the right people. Ive successfully used AT commands in Hyperterminal to establish a data connection on a Huawei modem. Why? Just experimenting. at OK at+cops? +COPS: 0,2,"65510",2 OK at+csq +CSQ: 4,99 OK...

    How to read APIs (Python)(PyBrain)

    Thanks for all the help everyone. I tried the modindex first. But its links into the API. Going up the class tree didnt reveal anything new to me as far as **args go. Well I tried the google group first. It looked somewhat active, but after 12 hours of no response I decided to read the code...

    How to read APIs (Python)(PyBrain)

    I am having trouble getting the hang of understanding APIs. After going through tutorials I find myself wanting to see what parameters I can pass to an object. So I look in the api and I see stuff like *args and **kwargs e.g...

    Log Identity Proofs: Simplifying a^{log_{b}(c)}=c^{log_{b}(a)}

    Homework Statement a^{log_{b}(c)}=c^{log_{b}(a)} The Attempt at a Solution Take log_{a} of both sides: log_{a}(a^{log_{b}(c)})=log_{a}(c^{log_{b}(a)}) gives: log_{b}c=log_{b}alog_{a}c Looks like one more step for the RHS. I sort of see that the RHS should become log_{b}c and...

    Trouble with algebra at the end of an elasticity problem

    I have a spherical shell with inner radius a_{1} and outer radius a_{2} I have worked out that the tension at r=a_{1} is \tau=\frac{2a_{1}^3+a_{2}^3}{2(a_{2}^{3}-a_{1}^{3})}P_{1} (P_{1} is pressure from the inside of the shell, causing the tension. Now if the shell is not very thick...

    How Should Initial Values Be Handled When Calculating EMAs in Java?

    I am not an expert on the subject. But I'm not sure how many people here are familiar with this so I'll give an input and someone else can possibly correct me. Firstly, your calculations are correct. Second, Your EMA starts on day 12. So your EMA plot obviously starts there. For your MACD...

    Basic tensors. Drawing and orienting.

    What is the rule for orienting tensors? In the above image we have the components of the Cauchy Stress Tensor in 2 dimensions. In the bottom left you see the cartesian co-ordinates are oriented as normal. How do I know \sigma_{xy} is oriented upwards on the right face and downwards on the...

    Why do we need markup languages?

    As someone mentioned above you can use Dreamweaver to generate html documents. This is a GUI. It can make life much easier in many instances. Even so, you are still generating html code which can be understood by webbrowsers. Lets assume you wanted to use "Microsoft Word" or any other...
