• PHP: prevent invocation of method X from from context != Y

  - by sunwukung

  This is a tricky one. I am "emulating" ZF Bootstrapping (surface appearance). Don't ask me why, call it academic interest. So I have a Bootstrap Abstract with a method "run" that iterates over itself to locate any methods prefixed with "init". The application looks for a user defined class which extends this class, in which the user can define any number of methods in this way. However, I want to prevent the user from being able to execute the "run" command of it's parent class, while still exposing the same command for the client code. Anyone got any thoughts/advice/guidance? regards SWK

• Which tools helps to start Ubuntu GUI when boot?

  - by Vimal Kumar

  I am on the way to create a Live CD from scratch. I used Virtual Box for this purpose. I installed Ubuntu base from ubuntumini.iso and installed gnome-shell. And installed Remastersys and created a backup.iso. Burned in a CD and boot from a PC. It end in CLI. Not lead to GUI. I tried the same ISO in VirtualBox. But it work properly there. I think I missed some packages which help to start GUI. Can you help me to identify the packages missed to include in the CD?

• Netlogo behaviorspace, How to export each experiment's plot in a separate directory with a unique name? (Answer is by using pathdir extension)

  - by Marzy

  I have a save-plots function which I call it in my final command of behavior space to export selected plots, I could create unique names for plots so they don't replace each other, for example my output file name for one of the plots is like this: DeathRates, PS true, HCHA false 100,true.csv Let FileNameDeathRates ( word "D: /Results/" "DeathRates, " "PS "PS? ", HCHA " HCHA? MPS "," CV? ".csv" ) So far is good, but I want is to have a directory with name of the experiment and export all plots of that experiment in that directory for example: Let DirName( word "D:/Results/" "PS "PS? ", HCHA " HCHA? MPS "," CV? ) Netlogo already exports plots with proper name and I just want the directory name to be different , and of course prior to the experiment the directory does not exist so the directory should be created first , I could not find a command to create a directory in netlogo without pathdir extension. Any idea on how can I do this? Thanks in advance ;)

  - by Jingqiang Zhang

  OS : Ubuntu 12.04 Now I want to use Backup and Whenever gem to automatic backup my database.

• How to use pom.xml/Maven to initialize a local thoughtsite (App Engine sample) project in Eclipse?

  - by ovr

  This sample app ("thoughtsite") for App Engine contains a pom.xml in its trunk: http://code.google.com/p/thoughtsite/source/browse/#svn/trunk But I don't know what command to run in Maven to set up the project locally. (The README doesn't mention anything about Maven.) I tried to just import the project code directly into Eclipse but it doesn't look like it's in an appropriate format for a direct import. So I assume I need to do something with Maven to get it set up correctly. I haven't really used Maven before so I'm not sure what command I would need to run to set everything up. The pom.xml seems like it downloads a bunch of dependencies for the project like the Spring jar files which I don't see anywhere else in the svn repository.

• C++ iostream not setting eof bit even if gcount returns 0

  - by raph.amiard

  Hi I'm developping an application under windows, and i'm using fstreams to read and write to the file. I'm writing with fstream opened like this : fs.open(this->filename.c_str(), std::ios::in|std::ios::out|std::ios::binary); and writing with this command fs.write(reinterpret_cast<char*>(&e.element), sizeof(T)); closing the file after each write with fs.close() Reading with ifstream opened like this : is.open(filename, std::ios::in); and reading with this command : is.read(reinterpret_cast<char*>(&e.element), sizeof(T)); The write is going fine. However, i read in a loop this way : while(!is.eof()) { is.read(reinterpret_cast<char*>(&e.element), sizeof(T)); } and the program keeps reading, even though the end of file should be reached. istellg pos is 0, and gcount is equal to 0 too, but the fail bit and eof bit are both ok. I'm running crazy over this, need some help ...

• Using a ICollection Value in sqlite SELECT parameterized statment

  - by case23

  Im trying to get all the entrys from a sqlite Database which have the same name as the keys in a Hashtable. My Statement looks like this. // the keys from the hashtable are names equivalent // to name entrys in the SomeTable Names Collumn Hashtable names; String query = "SELECT Id, Name FROM SomeTable WHERE Name LIKE (@Names)"; SQLiteCommand command = new SQLiteCommand(query, _databaseConnection); command.Parameters.AddWithValue("@Names", names.Keys); SQLiteDataReader reader = reader.ExecuteReader(); while(reader.Read()) { Console.WriteLine("Name: {0}, ID: {1}", reader[1].ToString(), reader[0].ToString()); } Im totally sure there are similar values in the Database, but i get nothing back and the reader does not execute. Is it impossible to add a ICollection as a Parameter Value so i need to start the reader only one time?

• What is the situation about OpenGL under Ubuntu Unity and Gnome3?

  - by user827992

  In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.

• SOCKET chat C# with private messaging

  - by Sergei

  I want to create SOCKET chat(server + clients) with private messaging. When client write smth to stream, he should notify server that it is private message for user X, how can i do this? Actually i can do smth like this: string command = "PRIV|" + txtMessage.Text; swSender.WriteLine(command); but i think it isn't good, for example if user wants send message like our "PRIV|" flag it will be errors public class TestChat { private StreamWriter swSender; private IPAddress ipAddr; private void InitializeandSend() { //ip from text box ipAddr = IPAddress.Parse(txtIp.Text); // Start a new TCP connections to the chat server tcpServer = new TcpClient(); tcpServer.Connect(ipAddr, 1986); //... //sending message from text box swSender.WriteLine(txtMessage.Text); swSender.Flush(); } }

• forward sudo verification

  - by Timo Kluck

  I often use the following construct for building and installing a tarball: sudo -v && make && sudo make install which will allow me to enter my password immediately and have everything done unattended. This works well except in the rare case that building takes longer than the sudo timeout, which may happen on my rather slow machine with large projects (even when using make -j4). But when the build takes a long time, that's exactly when doing things unattended has a great advantage. Can anyone think of a shell construct that allows me to input my password immediately, and which has make executing under normal permissions and make install under elevated permissions? For security reasons, I don't want to configure my user to use sudo without password. A viable option is to set the timeout to very long, but I'm hoping for something more elegant.

• SMS war continues, ideas welcome

  - by Pavel Radzivilovsky

  I am trying to make U9 telit modem send SMS messages. I think I handle protocol correctly, at least, I manage to send them, but only under these circumstances: the native application was executed beforehand, and killed by task manager (without giving it a chance to initialize things). It looks like the supplied application is good at doing certain initialization/deinitialization which is critical. I also see the difference between the two states in output of AT+CIND command. When I am trying to do things on my own, it returns zeroes (including signal quality), but when I run the same command after killing the native application, the output looks reasonable. I am out nearly of ideas. I have tried many things, including attempts to spy at modem's COM ports (didn't work). Haven't tried setting windows hooks to see what the application is trying to get thru. Perhaps you have encountered a similar situation?

• Setting application affinity in gdb

  - by Marcus Ahlberg

  Is there a simple way of setting the affinity of the application I'm debugging without locking gdb to the same core? The reason why I'm asking is that the application is running with real time priority and it needs to run on a single core. At the moment I use this command line taskset -c 3 gdbserver :1234 ./app.out but the application stops responding and freezes the gdb server, making debugging impossible. I suspect that the real time priority of the application prevents gdb from executing. If I start the application and then start gdb without affinity setting, then I can attach and debug the application without gdb freezing. Is there a simple way to start gdb and the application with different affinities? Or preferably: Is there a gdb command to set affinity of the child process?

• No unity-greeter.conf file in /etc/lightdm/

  - by drofart

  I am running Ubuntu 12.04 with gnome-shell. I have two admin user accounts. Now, I used to know that in Precise we can set different different login wallpaper to different different user, so I tried with: sudo dbus-send --system --print-reply --dest=org.freedesktop.Accounts /org/freedesktop/Accounts/User1001 org.freedesktop.Accounts.User.SetBackgroundFile string:/usr/share/backgrounds/Green-wallpaper-27.jpg but to no avail. Then I tried sudo xhost +SI:localuser:lightdm sudo su lightdm -s /bin/bash gsettings set com.canonical.unity-greeter background '/path/to/the/wallpaper.png' It does change my login wallpaper but for all users. Then I tried to locate /etc/lightdm/unity-greeter.conf but I found that it is not there. So where is it and how can I set different login wallpapers for different users?

• DOS batch script to list folders that have a specific file in them

  - by Lee

  I'm trying to create a file that has a list of directories that have a specific file name in them. Let's say I'm trying to find directories that have a file named *.joe in them. I initially tried just a simple dir /ad *.joe dir_list.txt , but it searches the directory names for *.joe, so no go. Then I concluded that a for loop was probably my best bet. I started with for /d /r %a in ('dir *.joe /b') do @echo %a dir_list.txt and it looked like it wasn't executing the dir command. I added the "usebackq", but that seems to only work for the /F command extension. Ideas?

• printing long compilation lines with MS NMAKE

  I have a legacy MS NMAKE Makefile I need to fix a few bugs in. There are some very long command lines I wish to debug that are being executed using the NMAKE trick of "inline files": dep: cmd @<<tmpfilename cmd_args.. << When changing the line to dep: echo cmd @<<tmpfilename cmd_args.. << NMAKE complains that the line is too long. Is there any other trick I can apply in order to view the command line NMAKE is actually executing?

• Ubuntu doesn't find hdds with higher clock rates

  - by user136243

  I dual boot windows 7 64-bit and ubuntu 13.10 64-bit on separate disks, and utilize some overclocking from the BIOS. Windows works fine, however ubuntu can't seem to find any hard drives, except for at stock cpu speeds. While attempting to boot it says Gave up waiting for root device... and ALERT! /dev/sdb7 does not exist. Dropping to shell! A bootable usb stick still works, but gparted doesn't detect any other drives. Have tried: Boot-repair Changing SATA mode in BIOS Newer kernels Older ubuntu versions Not sure it's relevant, but the motherboard is a Gigabyte GA-A75M-UD2H with the newest BIOS version, the CPU an AMD Llano. This is hardly a fatal error, but it's inconvenient to change BIOS settings whenever I want to switch OS, and furthermore I'm quite curious about why it won't work. I'd appreciate any insight into what the actual problem is. So how can I resolve this issue ?

• Why is my Quickly app full of fail?

  I tried to use quickly on Ubuntu 12.04 to create an application, but it does not behave as described in that linked page. I don't get a popup when creating the application (see error below). % quickly create ubuntu-application foo Creating project directory foo Creating bzr repository and committing Launching your newly created project! (foo:16847): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Congrats, your new project is setup! cd /tmp/foo/ to start hacking. It creates a project, but when I try to run, it crashes and burns: % cd foo % quickly run (foo:22639): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.interface' is not installed Is this because I'm not using gnome-shell? What can I do to get a working project? (Edit: As a side note, I'd be willing to debug this myself, but I don't even get a traceback. What do I have to do to get quickly to give me a traceback?)

• Develop Rails app on Mac using with TextMate Tutorial

  - by Meltemi

  I've found this a somewhat dated tutorial for developing a Rails application on Leopard with XCode. Wondering if anyone knows of a more up-to-date (ideally Mac based) tutorial that uses TextMate (or XCode if it's indeed preferred, or even just the command line). TextMate is appealing to me but wondering how to work scrips like ruby script/generate controller etc. into workflow or if switching between command-line & TextMate is standard operating procedure... If it matters were have Snow Leopard clients and Leopard Servers at our disposal. Thanks..

• Attach Console to Service

  - by MemphiZ

  I currently have a WCF Service Library which will be started through a Console Application acting as ServiceHost. The ServiceHost starts the service and then waits with Console.ReadLine() for the "quit" command. If i do "Console.WriteLine();" in the service this will be printed to the ServiceHosts Console of course. The Service prints some information when the clients connect for example. Is it possible to have the ServiceHost converted to a real Windows Service (to start up when the machine boots without console window) and attach or detach a command prompt (cmd.exe) or another Console Application to it when needed? For example if I want so see which clients connect from now on? Thanks in advance!
