  • Random Between: using random with the instance_create function in GML

    - by CLockeWork
    Hopefully this should be a simple one; I want to restrict the points that instances enter the screen from so they don't come in at the edges. In Game Maker I'm using the following code instance_create(random(room_width), random(-100) - 50, obj_enemy1); to create the instance off screen (create(x, y, ...)) At the moment I'm just using the room_width to define the max width for the random on x, but ideally I want to find a way of defining a max AND min width for the random. I can't figure out how to restrict the range on the x axis to between say 100 and 350. Any help would be appreciated. Cheers

  • vsftpd: chroot_local_user causes GNU/TLS-error

    - by akrosikam
    Distro: Ubuntu 12.04.2 Server 32-bit Server client: vsftpd 2.3.5 (from default "main" repository) Problem: Since upgrading from Ubuntu 10.04 to Ubuntu 12.04 (nothing changed on client-side), vsftp has refused to make chroot-jails with the "chroot_local_user" directive on FTP(e/i)S-connections. Here's my vsftpd.conf: anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES xferlog_std_format=YES ftpd_banner=How are you gentlemen. listen=YES pam_service_name=vsftpd userlist_enable=YES userlist_deny=NO tcp_wrappers=YES connect_from_port_20=YES ftp_data_port=20 listen_port=21 pasv_enable=YES pasv_promiscuous=NO pasv_min_port=4242 pasv_max_port=4252 pasv_addr_resolve=YES pasv_address=your.domain.com ssl_enable=YES allow_anon_ssl=NO force_local_logins_ssl=YES force_local_data_ssl=YES ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO rsa_cert_file=/home/maw/ssl_ftp_test/vsftpd.pem rsa_private_key_file=/home/maw/ssl_ftp_test/vsftpd.pem debug_ssl=YES log_ftp_protocol=YES ssl_ciphers=HIGH chroot_local_user=NO How to reproduce: Have a working SSL/TLS-secured vsftpd-configuration (I suggest similar to the one above) ready. Try to connect with an FTP user client and upload some files. With my setup, the above listed config works well at this point. Edit /etc/vsftpd.conf and set chroot_local_user= to YES. Make sure that chroot_list_enable= and/or chroot_list_file= are not set. Comment them out if they are. Save and exit. Run sudo restart vsftpd (or sudo service vsftpd restart if you like) in a terminal. Try to connect with an FTP user client. You should see a message more or less like this: GnuTLS error -15: An unexpected TLS packet was received. This is an issue for me, as I do not want FTP-sessions to be able to list files outside the user's home folder. I have checked with several client-side apps, and I get the same results with every one of them. Filezilla is not so good regarding cipher methods nowadays, but as I am able to make an FTP(e)s-connection over TLS (as long as chroot'ing is disabled and ssl_ciphers is set to HIGH) I have a feeling ciphers are not the issue this time, and that I won't find the answer by tweaking configs on the client side. My vsftpd.log stays empty, even though debug_ssl and log_ftp_protocol are enabled, so no info there either.

  • Detach current session and attach to another session, done with one script, can I?

    - by Jimm Chen
    After reading the vague official doc of GNU screen( http://www.gnu.org/software/screen/manual/screen.html ) and asking quite some questions at this site. I still cannot figure out how to accomplish such a task with a shell script. This task costs some words to describe. Assume I'm using PuTTY to telnet into my Linux server. ?STEP 1? Launch 2 telnet connections . From putty window 1 (PTWIN1),telnet into Linux Bash shell, execute screen -RR to launch a screen session, and get session name 21385.pts-4.linux-ic37 . From putty window 2 (PTWIN2), do that same as in PTWIN1, but this time, I get session name 22041.pts-9.linux-ic37 . Now, we have two screen sessions running simultaneously. We can check this: $ screen -ls There are screens on: 22041.pts-9.linux-ic37 (Attached) 21385.pts-4.linux-ic37 (Attached) 2 Sockets in /var/run/uscreens/S-chj2. ?STEP 2? Assume that for some reason, PTWIN1's TCP connection is lost abnormally(but server doesn't know that), and an urgent work is pending on session 21385 and I want to quickly regain control of it. Fortunately, we know the 21385 session is still there, so, I want to have PTWIN2 attach to session 21385. Because I hate to remember the esoteric screen option all the time, so I decide to write a script called sttach. I hope that sttach 21385.pts-4.linux-ic37 can let me attach to session 21385(for PTWIN2). Now, let's say sttach works well and I take control of 21385 on PTWIN2. ?STEP 3? Some minutes later. I want to go back to work on session 22041. Here, please allow me to have PTWIN2 remain associated with session 21385. What I would like to do is to launch another putty window (PTWIN3), telnet into server, and execute sttach 22041.pts-9.linux-ic37 in hope that I can resume session 22041 on PTWIN3 . You can see the benefit of sttach: as long as I know the target session name, I can call it to have my PuTTY window switch to that session, regardless whether the target session is "(Attached)" or "(Detached)", and regardless whether the running context is inside a screen session or not. Now the question: How to write the (Bash) script sttach? I mean, run screen with appropriate options in sttach to accomplish the goal. Waiting for your kind answer. Thank you. My previous questions regarding GNU screen: GNU screen, how to get current sessionname programmatically Is it possible to change GNU screen session name after created? How do I know I'm running inside a linux "screen" or not? My env: openSUSE Linux 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

  • GNU/Linux interactive table content GUI editor?

    - by sdaau
    I often find myself in the need to gather data (say from the internet), into a table, for comparison reasons. I usually need the final table output in HTML or MediaWiki mostly, but often times also Latex. My biggest problem is that I often forget the correct table syntax for these markup languages, as well as what needs to be properly escaped in the inline data, for the table to render correctly. So, I often wish there was a GUI application, which provides a tabular framework - which I could stick "Always on Top" as a desktop window, and I could paste content into specific cells - before finally exporting the table as a code in the correct language. One application that partially allows this is Open/LibreOffice calc: The good thing here is that: I can drag and drop browser content into a specifically targeted table cell (here B2) "Rich" text / HTML code gets pasted For long content, the cell (column) width stays put as it originally was The bad thing is, that: when the cell height (due to content size) becomes larger than the calc window, it becomes nearly impossible to scroll calc contents up and down (at least with the mousewheel), as the view gets reset to top-right corner of the selected cell calc shows an "endless"/unlimited field of cells, so not exactly a "table" - which I find visually very confusing (and cognitively taxing) Can only export table to HTML What I would need is an application that: Allows for a limited size table, but with quick adding of rows and columns (e.g. via corresponding + buttons) Allows for quick setup of row and column height and width (as well as table size) Stays put at those sizes, regardless of size of content pasted in; if cell content overflows, cell scrollbars are shown (cell content could be possibly re-edited in a separate/new window); if table overflows over window size, window scrollbars are shown Exports table in multiple formats (I'd need both HTML and mediawiki), properly escaping cell content for each (possibility to strip HTML tags from content pasted in cells, to get plain text, is a plus) Targeting a specific cell in the table for the content paste operation is a must - it doesn't have to be drag'n'drop though, a right click over a cell with "Paste content" is enough. I'd also want the ability to click in a specific cell and type in (plain text) content immediately. So, my question is: is there an application out there that already does something like this? The reason I'm asking is that - as the screenshots show - for instance Libre/OpenOffice allows it, but only somewhat (as using it for that purpose is tedious). I know there exist some GUI editors for Linux (both for UI like guile or HTML like amaya); but I don't know them enough to pinpoint if any of them would offer this kind of functionality (and at least in my searches, that kind of functionality, if present in diverse software, seems not to be advertised). Note I'm not interested in styling an HTML table, which is why I haven't used "table designer" in the title, but "table editor" (in lack of better terms) - I'm interested in (quickly) adjusting row/column size of the table, and populating it with pasted data (which is possibly HTML) in a GUI; and finally exporting such a table as self-contained HTML (or other) code.

  • GNU Octave - question about graphs and plotting

    - by Twórca
    I've had task to do - to make an graphical interpretation of adding two functions together: sin(8x) and multiplied -sign(x) in Octave, as shown on image above. And I've done that, but I don't know how to get rid of these lines, which link up gaps between separated values (for example, -1 and 1). I don't want them to be seen especially in third graph. To make helping me easier, I'm going to tell you what I did: I made linear series of numbers, from -100 to 99 (tempx). tempy = -sign(tempx) y1 = [tempy tempy tempy tempy] (this line is kinda funny, if you know Polish language) Creating y2 - sinus function y3 = y2 + y1 Plotting, subplotting... Screenshot Awaiting for instructions...

  • using GNU GPL v2 software as pointers to solution to problem

    - by Patrick
    I am coding a PHP serial access class and have been taking pointers from the PHP-serial class on Google Code (here). That class is based on PHP 4 and I'm creating a PHP 5 class that allows more functionality and is specific to some business demands I have. There is no code copied and I have done all the coding. Does the class I'm writing fall under the Google Code's GPL or am I free to select a license that I feel is appropriate? I'm not sure of the standard that applies to licensing when you are only looking to another work for pointers.

  • Beyond Makefiles: GNU make is For More Than Just Compiling

    <b>LinuxPlanet: </b>"You've probably encountered 'make' as a compile tool, used for turning source code into executables (make; make install). However, make can do a lot more than just that. You can use it to automate pretty much any process which involves running a set of commands on source files."

  • Mount "locked" SD card as read-write in GNU/Linux

    - by Vi
    My Canon PowerShot A470 + CHDK can write to SD-cards that are "locked" (the lock switch is used to make the card bootable), but GNU/Linux `/dev/mmcblk1': Read-only file system (I'm using "Texas Instrument 5-in-1 Multimedia Card Reader") So I have to switch that switch on and off again and again. ("unlocked" to write to the card in Linux, "locked" to boot the camera from it). How to force locked card to be writable in GNU/Linux?

  • GNU Emacs is crashing with -nw

    - by Jack
    When I run emacs with -nw option, the emacs really open, but I can't do more nothing. As if the user input is blocked and no keyboard signal is received and/or interpreted. I've tried run without load .emacs file and some other behaviors: emacs -nw -Q --no-desktop --debug-ini foo.c But makes no difference and strangely the GUI-version(using Gtk) is working fine. My gnu-emacs version is GNU Emacs 23.3.1 Any help to help to fix it is very appreciated.

  • Removing all traces of GNU java and openjdk and replacing with Sun JDK

    - by user61766
    I have installed latest Sun JDk. But when I do: java -version I still got OpenJDK version. So I completely removed OpenJDK. But now when I do: java -version I get even older GNU java 1.5 something libgcj. So I completely removed that too but it was asking to remove bunch of dependent apps like OpenOffice.org Writer etc. Even though I need the writer, I let it go because I do not want ever to see the face of any GNU java on my linux. So everything related to GNU java is removed. Luckily I am able to start Eclipse and it works fine and start normally (apparently using the installed Sun JDK which is what I want). But now when I run java -version I get bash: /usr/bin/java: No such file or directory Now what I need to do so that when I open any terminal window and enter java -version I should get Sun JDK version? Sun JDK is installed in /usr/java/jdk1.6.021. I also have symlinks: /usr/java/latest and /usr/java/defaults pointing to sun jdk.

  • How can I keep gnu screen from becoming unresponsive after losing my SSH connection?

    - by Mikey
    I use a VPN tunnel to connect to my work network and then SSH to connect to my work PC running cygwin. Once logged in I can attach to a screen session and everything works great. Now, after a while, I walk away from my computer and sooner or later, the VPN tunnel times out. The SSH connection on each end eventually times out and then I eventually come back to my computer to do some work. Theoretically, this should be a simple matter of just restarting the VPN, reconnecting via SSH, and then running "screen -r -d". However apparently when the sshd daemon times out on the cygwin PC, it leaves the screen session in some kind of hung state. I can reproduce a similar hung state by clicking the close box on a cygwin bash shell window while it's running a screen session. Is there any way to get the screen session to recover once this has happened, so that I don't lose anything?

  • How to build gnu `libiconv` on & for windows?

    - by claws
    Hello, I want to build a static library (*.LIB file) GNU libiconv on windows to be used with other libraries in Visual C++. Other libraries I'm using are built with "MultiThreaded DLL" (/MD) Runtime option. So, I need to build libiconv with the same option. Problem is the libiconv uses GNU build system and I want to compile with /MD option. You can see the source structure of libiconv here: http://cvs.savannah.gnu.org/viewvc/libiconv/?root=libiconv Actually, Mr. Zlatkovic maintains the windows port of GNU libiconv for libxml2 you can see them here: ftp://xmlsoft.org/libxml2/win32/iconv-1.9.2.win32.zip ftp://xmlsoft.org/libxml2/win32/iconv-1.9.2.win32.zip I cannot use his port. I need to build from the latest version of libiconv-1.13. I wonder how this guy has ported it? Can some one please tell me how to build *.lib from this and compile it using MSVC?

  • gnu make installed with OS language

    I installed the latest GNU make to my windows machine. The installer decided to setup the language as the OS language, which I did not get prompted for. I want it to be english. My OS is in swedish. I remember I had similar problem with another GNU program (can't recall which), which was solved by adding the env var "lang" with value "c". How can I switch the language of GNU make to english?

  • GNU/Linux developement n00b needs help porting C++ application from windows to GNU/Linux.

    - by AndrejaKo
    Hi! These questions may not be perfectly suited for this site, so I apologize in advance for asking them here. I'm trying to port a computer game from windows to GNU/Linux. It uses Ogre3D,CEGUI, ogreogg and ogrenewt. As far as I know all dependencies work on GNU/Linux and in the game itself there is no ooze-specific code. Here's the questions part: Is there any easy way to port visual studio 2008 project to GNU/Linux tool-chain? How do I manage dependencies? In Visual Studio, I'd just add them in property sheets or default directories. I assume on GNU/Linux autoconf and make take care of that, but in which way? Do I have to add each .cpp and .hpp manually or is there some way to automate things? How do I solve the problem of dependencies on different locations on different systems? I'd like to use Eclipse as IDE under GNU/Linux. I know that the best answer to most of my questions is RTFM, but I'm not sure what I exactly need and where to start looking.
