root

问题 Hi I can login to the GCE VM with WinSCP using my own username, cannot login as root...this is by default according to Google, and can be changed. Changed like this: Step 1: Login SSH and Su Root # sudo su root Step 2: Change password Root #passwd root Step 3: Config SSHD allow Root login #nano /etc/ssh/sshd_config PermitRootLogin yes PasswordAuthentication yes #service sshd restart (I used ssh as I'm using ubuntu and sshd wouldn't work) Tried to login as root via WinSCP but I get "Received

问题 when I use this code Runtime.getRuntime().exec("su"). and listen to the ErrorStream it gives me back: Permission denied. However SuperUser successfully grants permissions. Any Ideas? 回答1: You need to add to your AndroidManifest.xml <uses-permission android:name="android.permission.ACCESS_SUPERUSER"/> 回答2: My ROM was messed up. I had to reinstall it. Adding a permission should NOT help. Edit: SuperUser is now giving warning if you don't define the permission, how ever it will still grant su.

问题 I did a backup restore on my phone Cherry Mobile Infinix Pure XL (Model: X210) and I found out that USB-OTG is not working. So I take a look on the permissions folder (reference: Youtube video) and noticed that android.hardware.usb.host.xml is missing. I did a lot of research on how to add this file in that directory but nothing works. I just did this https://superuser.com/questions/126073/chmod-to-allow-read-and-write-permissions-for-directory this http://forum.xda-developers.com/showthread

问题 I'm writing a program that solves an integral by Legendre-Gauss quadrature. The algorithm for nth-order quadrature requires, at one point, finding the roots of the nth-order Legendre polynomial, Pn(x), assigning them to the array Absc (for 'abscissa'). Pn is an nth order polynomial with n independent real roots on the interval [-1,1]. I'd like to be able to compute the roots, instead of just importing them from some library. I am able to create an array that gives the polynomial coefficients,

问题 When building a static HTML site, you can set the base url like so <base url="http://localhost:8888/mysite" /> . Supposedly when you insert, say, an image, you can do so from that base url like so <img src="/img/logo.png" /> , which is equivalent to <img src="http://localhost:8888/mysite/img/logo.png" /> My problem is that these relative links don't work when I move the site around, which is a pain because I'm trying to share it with someone on Dropbox. I thought I could just chage the base
