If a user wants to execute a command, he has to first log in into a system. But some users in the system have /bin/false or /sbin/nologin set as a default shell in the /etc/password file. If I change /bin/bash to /bin/false in case of my user, I won't be able to log in into the system, so I also won't be able to run commands. But the shellless users do it anyway: How can a user without a shell execute a command? In POSIX, every running process has three User IDs (UIDs) associated with it; the real UID, which identifies the user who launched the process, the effective UID, which is used to determine what resources the process can access, and the saved Set-User-ID (SUID), which is the effective UID the process had when it started (at the point of the last exec() call). Of these, the effective UID is the most significant, since it is the one used when determining access control decisions regarding the process.

I’ve decided to try my hand at 3D reconstruction using a stereo camera. There are a few good sets of instructions on how to get started with this. I decided to take some heavy inspiration from them and will be citing them as I go in the post. I ended up not following any of the instructions precisely because I have a few goals that are not fulfilled by any single source that I could find

Here is the output to some inspection that I did. With that in mind, how do I go about changing the default to 1.6 so that when I execute java -version, it tells me 1.6? I am on Fedora but I hope that alternatives works the same way on Ubuntu. You need to run update-alternatives --config java (on Fedora just alternatives --config java) to see what options you have. Then type the number of the JDK you want to use and press enter.

PageDown is the version of Attacklab's Showdown and WMD as used on Stack Overflow and the other Stack Exchange sites. It includes a converter that turns Markdown into HTML, a Markdown editor with realtime preview of the generated HTML, and a few useful plugins, e.g. for sanitizing the generated HTML according to a whitelist of allowed tags. The Markdown converter can be used both in the browser (usually in conjunction with the editor, to display a real time preview), and on the server using Node.JS.

Let's Talk About Technology Today user experience is painful because technology makes things complex. The truth is that all our devices speak in different languages. This confusion leads to arguments and dissatisfaction adding unnecessary stress. We created the STACK Box so your technology is easy to use and your devices work together, and work with existing internet services or the cloud.

I'm designing an ESC with a small microcontroller running at 3.3V. The BLDC motors I have chosen are extremely small, and run best at 3.7V. I have the power supply for both of these (3.7V is VBATT, 3.3V is obtained using a buck converter). They are 3 phase, and the controller needs to be sensorless. I would like to measure RPM and current usage as well if it doesn't mean I will have an overly complicated design. All the docs I have found are great for higher voltages, and ridiculous currents (I will max out at ~5Amps at 3.7V, I don't necessarily need to design a 100V, 300A ESC). Questions I have: Is there a reference design I can follow somewhere around the net? What kind of protection circuitry should I use? How simple can I go? Are there any ICs that will simplify the circuit even further? Any other recommendations/tips/pointers?

I am looking for installing a git server to share projects with my team. I don't want to create a user account on the server with SSH access for each developer that needs a git access. It seems there is two concurrent solutions that cover this issue : gitosis & gitolite. I could not find any comparison between both solutions. What are the main differences between them? Are there other similar solution?

Ok, apparently setChildIndex() only sets the display index number of the item in the container (item #1 to display, item #2 to display, etc.), but doesn't have anything to do with z-index (i.e., layering items on top of one another)? This is exactly what it does!
