  • Mount drive on remote machine

    - by NikolaiDante
    My current set up is: I have my main machine (Darkseid) upstairs which has a drive with all my films on it, which I don't keep mounted. Downstairs, next to the tv, I have a htpc (Archangel) which has xbmc installed on it, which points to a samba share on the main machine. Everything works fine when the drive is mounted, but is there a script I can write to send a command to the upstairs machine from the downstairs machine to mount the drive to save the walk upstairs? #lazy Both machines are Ubuntu 12.04

  • Still prompted for a password after adding SSH public key to a server

    - by Nathan Arthur
    I'm attempting to setup a git repository on my Dreamhost web server by following the "Setup: For the Impatient" instructions here. I'm having difficulty setting up public key access to the server. After successfully creating my public key, I ran the following command: cat ~/.ssh/[MY KEY].pub | ssh [USER]@[MACHINE] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" ...replacing the appropriate placeholders with the correct values. Everything seemed to go through fine. The server asked for my password, and, as far as I can tell, executed the command. There is indeed a ~/.ssh/authorized_keys file on the server. The problem: When I try to SSH into the server, it still asks for my password. My understanding is that it shouldn't be asking for my password anymore. What am I missing? EDIT: SSH -v Log: Macbook:~ michaeleckert$ ssh -v [USER]@[SERVER URL] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 53: Applying options for * debug1: Connecting to [SERVER URL] [[SERVER IP]] port 22. debug1: Connection established. debug1: identity file /Users/michaeleckert/.ssh/id_rsa type -1 debug1: identity file /Users/michaeleckert/.ssh/id_rsa-cert type -1 debug1: identity file /Users/michaeleckert/.ssh/id_dsa type -1 debug1: identity file /Users/michaeleckert/.ssh/id_dsa-cert type -1 debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_6.2 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.5p1 Debian-6+squeeze3 debug1: match: OpenSSH_5.5p1 Debian-6+squeeze3 pat OpenSSH_5* debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Server host key: RSA [STRING OF NUMBERS AND LETTERS SEPARATED BY SEMI-COLONS] debug1: Host ‘[SERVER URL]' is known and matches the RSA host key. debug1: Found key in /Users/michaeleckert/.ssh/known_hosts:2 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,password debug1: Next authentication method: publickey debug1: Trying private key: /Users/michaeleckert/.ssh/id_rsa debug1: Trying private key: /Users/michaeleckert/.ssh/id_dsa debug1: Next authentication method: password [USER]@[SERVER URL]'s password: debug1: Authentication succeeded (password).

  • Can someone explain how a GUI works and when I should start using one?

    - by David
    I've been learning C++ for about a month now, and before I go any further, I'd like to clear up this tedious question I keep on having. I know what a GUI is, but I don't really know how it works, and maybe examples of popular ones...? Although I know command line programming is the bare fundamentals, I think it'd be fun messing around with a GUI. Although I have around 3 million other questions, I'll save them :D

  • How can I log key presses in Game Maker?

    - by skeletalmonkey
    I'm trying to create a log of a players actions as they play a game of Spelunky. The easiest I've found to do this is to log what keys are pressed at each frame. What I don't know how to do is how to integrate this with the Game Maker source code of Spelunky. Is there a specific way to create a script that is checked every frame/tick (don't know the right term) and a command to find what buttons are pressed?

  • Multiplayer tile based movement synchronization

    - by Mars
    I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

  • Parallel Port Problem in 12.04

    - by Frank Oberle
    I have a “dumb” printer attached to a parallel port in my machine which works fine under the “other” resident operating system (from Redmond) on the same machine. I recently added Ubuntu 12.04 as a dual boot on the machine, but Ubuntu doesn't seem to recognize the parallel port at all. All I need to set up a printer is a really plain-vanilla fixed pitch text-only generic driver, which is present, but no parallel ports show up. (The other printers, all on USB ports, seem to work just fine). Following what appeared to me to be the most reasonable of the many conflicting pieces of advice on the web, here's what I did: I added the following lines to /etc/modules parport_pc ppdev parport Then, after rebooting, I checked to see that the lines were still present, and they were. I ran dmesg | grep par and got the following references in the output that seemed like they might have to do with the parallel port: [ 14.169511] parport_pc 0000:03:07.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 [ 14.169516] PCI parallel port detected: 9710:9805, I/O at 0xce00(0xcd00), IRQ 21 [ 14.169577] parport0: PC-style at 0xce00 (0xcd00), irq 21, using FIFO [PCSPP,TRISTATE,COMPAT,ECP] [ 14.354254] lp0: using parport0 (interrupt-driven).

I was still unable to add a printer for my old clunker, so I tried the direct approach, typing echo “Hello” > /dev/lp0 and received a Permission denied message. I then tried echo “Hello” > /dev/parport0 which didn't give me any message at all, but still didn't print anything. Running the command sudo /usr/lib/cups/backend/parallel gives the following: direct parallel:/dev/lp0 "unknown" "LPT #1" "" "" Checking the permissions for /dev/parport0, Owner, Group, and Other are all set to read and write. crw-rw---- 1 root lp 6, 0 Sep 9 16:37 /dev/lp0 crw-rw-rw- 1 root lp 99, 0 Sep 9 16:37 /dev/parport0 The output of the command lpinfo -v includes the following line: direct parallel:/dev/lp0 I've read several web postings that seem to suggest this has been a problem for several years, but the bug reports were closed because there wasn't enough information to address the issue (shades of Microsoft!). Any suggestions as to what I might be missing here?

  • Finding nuggets in ARC discussions

    - by alanc
    A bit over twenty years ago, Sun formed an Architecture Review Committee (ARC) that evaluates proposals to change interfaces between components in Sun software products. During the OpenSolaris days, we opened many of these discussions to the community. While they’re back behind closed doors, and at a different company now, we still continue to hold these reviews for the software from what’s now the Sun Systems Group division of Oracle. Recently one of these reviews was held (via e-mail discussion) to review a proposal to update our GNU findutils package to the latest upstream release. One of the upstream changes discussed was the addition of an “oldfind” program. In findutils 4.3, find was modified to use the fts() function to walk the directory tree, and oldfind was created to provide the old mechanism in case there were bugs in the new implementation that users needed to workaround. In Solaris 11 though, we still ship the find descended from SVR4 as /usr/bin/find and the GNU find is available as either /usr/bin/gfind or /usr/gnu/bin/find. This raised the discussion of if we should add oldfind, and if so what should we call it. Normally our policy is to only add the g* names for GNU commands that conflict with an existing Solaris command – for instance, we ship /usr/bin/emacs, not /usr/bin/gemacs. In this case however, that seemed like it would be more confusing to have /usr/bin/oldfind be the older version of /usr/bin/gfind not of /usr/bin/find. Thus if we shipped it, it would make more sense to call it /usr/bin/goldfind, which several ARC members noted read more naturally as “gold find” than as “g old find”. One of the concerns we often discuss in ARC is if a change is likely to be understood by users or if it will result in more calls to support. As we hit this part of the discussion on a Friday at the end of a long week, I couldn’t resist putting forth a hypothetical support call for this command: “Hello, Oracle Solaris Support, how may I help you?” “My admin is out sick, but he sent an email that he put the findutils package on our server, and I can run goldfind now. I tried it, but goldfind didn’t find gold.” “Did he get the binutils package too?” “No he just said findutils, do we need binutils?” “Well, gold comes in the binutils package, so goldfind would be able to find gold if you got that package.” “How much does Oracle charge for that package?” “It’s free for Solaris users.” “You mean Oracle ships packages of gold to customers for free?” “Yes, if you get the binutils package, it includes GNU gold.” “New gold? Is that some sort of alchemy, turning stuff into gold?” “Not new gold, gold from the GNU project.” “Oracle’s taking gold from the GNU project and shipping it to me?” “Yes, if you get binutils, that package includes gold along with the other tools from the GNU project.” “And GNU doesn’t mind Oracle taking their gold and giving it to customers?” “No, GNU is a non-profit whose goal is to share their software.” “Sharing software sure, but gold? Where does a non-profit like GNU get gold anyway?” “Oh, Google donated it to them.” “Ah! So Oracle will give me the gold that GNU got from Google!” “Yes, if you get the package from us.” “How do I get the package with the gold?” “Just run pkg install binutils and it will put it on your disk.” “We’ve got multiple disks here - which one will it put it on?” “The one with the system image - do you know which one that is? “Well the note from the admin says the system is on the first disk and the users are on the second disk.” “Okay, so it should go on the first disk then.” “And where will I find the gold?” “It will be in the /usr/bin directory.” “In the user’s bin? So thats on the second disk?” “No, it would be on the system disk, with the other development tools, like make, as, and what.” “So what’s on the first disk?” “Well if the system image is there the commands should all be there.” “All the commands? Not just what?” “Right, all the commands that come with the OS, like the shell, ps, and who.” “So who’s on the first disk too?” “Yes. Did your admin say when he’d be back?” “No, just that he had a massive headache and was going home after I tried to get him to explain this stuff to me.” “I can’t imagine why.” “Oh, is why a command too?” “No, _why was a Ruby programmer.” “Ruby? Do you give those away with the gold too?” “Yes, but it comes in the ruby package, not binutils.” “Oh, I’ll have to have my admin get that package too! Thanks!” Needless to say, we decided this might not be the best idea. Since the GNU package hasn’t had to release a serious bug fix in the new find in the past few years, the new GNU find seems pretty stable, and we always have the SVR4 find to use as a fallback in Solaris, so it didn’t seem that adding oldfind was really necessary, so we passed on including it when we update to the new findutils release. [Apologies to Abbott, Costello, their fans, and everyone who read this far. The Gold (linker) page on Wikipedia may explain some of the above, but can’t explain why goldfind is the old GNU find, but gold is the new GNU ld.]

  • Will Online Learning Save Higher Education (and does it need saving)?

    - by user739873
    A lot (an awful lot) of education industry rag real estate has been devoted to the topics of online learning, MOOC’s, Udacity, edX, etc., etc. and to the uninitiated you’d think that the education equivalent of the cure for cancer had been discovered. There are certainly skeptics (whose voice is usually swiftly trampled upon by the masses) who feel we could over steer and damage or destroy something vital to teaching and learning (i.e. the classroom experience and direct interaction with human beings known as instructors), but for the most part prevailing opinion seems to be that online learning will take over the world and that higher education will never be the same. Now I’m sure that since you all know I work for a technology company you think I’m going to come down hard on the side of online learning proselytizers. Yes, I do believe that this revolution can and will provide access to massive numbers of individuals that either couldn’t afford (from a fiscal or time perspective) a traditional education, and that in some cases the online modality will actually be an improvement over certain traditional forms (such as courses taught by an adjunct or teaching assistant that has no business being a teacher). But I think several things need immediate attention or we’re likely to get so caught up in the delivery that we miss some of the real issues (and opportunities) around online learning. First and foremost, we’ve got to give some thought to how traditional information systems are going to accommodate thousands (possibly hundreds of thousands) of individual students each taking courses from many, many different “deliverers” with an expectation that successful completion of these courses will result in credit at many or most institutions. There’s also a huge opportunity to refine the delivery platform (no, LMS is not a commodity when you are talking about online delivery being your sole mode of operation) as well as the course itself by mining all kinds of data from the interactions that the students have with the material each time they take it. Social data analytics tools will be key in achieving this goal. What about accreditation (badging or competencies vs. traditional degrees)? And again, will the information systems in place today adapt to changes in this area fast enough? The type of scale that this shift in learning could drive has the potential to abruptly overwhelm just about every system in place today in higher education. I would like to (with a not so gentle reminder) refer you back to a blog entry I wrote when I first stepped into my current role at Oracle in which I talked about how higher ed needs an “Oracle” more than at any other time in it’s evolution (despite the somewhat mercantilist reputation it has in some circles). There just aren’t that many organizations that can deliver the kinds of solutions “at scale” that this brave new world of online education will demand. The future may be closer than we think. Cole

  • On the art of self-promotion

    - by Tony Davis
    I attended Brent Ozar's Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a 'perfect storm' of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one's work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven't far more qualified and established commentators, MVPs and so on, already said it? While it's a good idea to pick reasonably fresh and interesting topics, it's more important not to let such fears lead to writer's block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn't always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications. However, others in the organization who are unaware of what's involved in getting an application that is 'done' ready for production may dismiss such efforts as fussiness or conservatism. At the dark end of the development cycle, chickens come home to roost, but their droppings tend to land on those trying to clear up the mess. My advice is this: next time you fix a bug or improve the resilience or performance of a database or application, make sure that you use team meetings, informal discussions and so on to ensure that people understand what the problem was and what you had to do to fix it. Use your blog to describe, generally, the process you adopted, the resources you used and the insights that came from your work. Encourage your colleagues to do the same. By spreading the art of self-promotion to everyone involved in an IT project, we get a better idea of the extent of the work and the value of the contribution of all the team members. As always, we'd love to hear what you think. This very week, Simple-talk launches its new blogging platform. If any of this has moved you to 'throw your hat into the ring', drop us a mail at [email protected]. Cheers, Tony.

    A new year is upon us and it’s also time for me to end my blogging vacations and get back to the blogosphere. However, let’s start simple… and short. More specifically with a quick way to detect the installed .NET Framework versions on a machine. You just need to fire up Internet Explorer, write the following in the address bar and press enter: javascript:alert(navigator.userAgent) If for any reason you need to copy/paste the resulting information then use the next command instead: javascript:document.write(navigator.userAgent)

    I installed lampp / xampp on my Ubuntu 12.04. After installing, Apache and MySQL were running properly. Now, they're not. Here's what I get when I try to run apache: Command: /etc/init.d/apache2 start Result: * Starting web server apache2 /usr/sbin/apache2ctl: 87: ulimit: error setting limit (Operation not permitted) (13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed.

    - by Indian
    I have ben using 12.10 for a few days. Just upgraded it from 12.04. This comp of mine, which has a 4GB RAM and 64 bit intel processor, just goes slow randomly. When I press Ctrl+Alt+F6 and login through a command prompt, I see a number of processes using - ps -A I get many instances of a process named 'doodle' running. So many that I have to 'pkill' them by hand. Any idea why this is happening?

  • What You Said: Staying Productive While Working from home

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your telecommuting/work-from-home productivity tips. Now we’re back with a tips and tricks roundup; read on to see how your fellow readers stay focused at home. By far and away the most common technique deployed as carefully isolating work from home life. Carol writes: I love working from home and have done so for 6 years now. I have a routine just as if I was going to an office, except my commute is 12 steps. I get ready for work, grab my purse and smart phone and go to up the steps to my office. I maintain a separate phone line and voice mail for work that I cannot answer from anywhere but my work desk. I use call forwarding when I travel so only my office phone number is published. I have VOIP phone service so I can forward calls from the internet if I forget, or need to change where the phone is forwarded. I do have a wired and wireless head set so I can go get a cold drink if on one of those long boring conference calls. I plan my ‘get off from work’ time and try to stick to it, as with any job some days I am late getting off, but it all works out. I make sure my office is for work only, any other computer play time is in a different part of the house on different computer. My office has laptop, dock, couple of monitors, multipurpose printer, fax, scanner, file cabinets – just like the office at a company. I just also happen to have a couple of golden retrievers that come to work with me and usually lay quietly until 5, and yes they know it is 5pm sometimes before I do. For me, one of the biggest concerns when working from home is not being unproductive, but the danger of never stopping work. You could keep going and going because let’s face it – the company will let you do it, so I set myself up to prevent that and maintain a separateness.

  • Unable to locate Grizzly packages in Ubuntu 13.04 Server

    - by user162681
    I have installed Ubuntu 13.04 server in my x86 based laptop and then added the desktop packages on top of it. I have downloaded all the packages using apt-get. I have MySQL, PostgreSQL, Python 3.3, etc. But I am unable to locate Grizzly-specific Nova, Swift, and Glance packages (OpenStack). I am using this command: dpkg -l | grep Nova dpkg -l | grep Glance etc. Isn't Ubuntu 13.04 Server supposed to come with Grizzly automatically?
