• Windows 7 installer doesn't recognize NTFS partition.

  - by ifesdjeen

  Hi, I'm trying to install windows 7 on my Macbook. I've created NTFS partition, but when i'm starting up Windows 7 installation, it says that i can't install windows on this partition, since drive already contains maximum amount of partitions with this filesystem type. I haven't heard of any limits on filesystems, but still i can't even format this drive from Win7 installer. I've found access to command line from win7 installation CD, but i can't find fdisk there to format. Do you have any idea on about how to deal with it?

• Enter response once prompt returns?

  - by mjb

  It's neither a secure idea nor one I'd recommend elsewhere, but I have a situation when occasionally it takes a while for my Ansible ad-hoc command to respond. I'd love to pipe or args or whatever is needed to push the required text into the prompt so I can walk away and know it will finish. Ex: $ ansible all -m shell -a "reboot" --ask-pass Password: blah blah blah it worked I'd love to send an argument or << or something to get the password in. Is that possible?

• No keyboard after suspend, even after hard reset

  - by subatomics

  all. While I was using a Ubuntu 9.1 live CD, I put the computer (Toshiba Satellite C655) into standby. After I resumed, the keyboard stopped functioning, though the mouse (USB) still worked. I decided to turn off the computer, but after Ubuntu shuts down, it asks you to press "enter" to actually turn the machine off. The keyboard was still dead, so I all I could do was use the on/off switch to power down the computer. Now, when I try to boot the computer, nothing happens. Before this problem, I would see a menu asking me to select an OS (I had Windows 7 and Windows XP installed). I cannot use any emergency measures because I need to press F12 to boot from a CD, and the keyboard is still not working. I tried removing the HD to force a boot from the CD, but it didn't work. I also tried to plug in a USB keyboard, which failed as well. Right now, I have no idea how to fix this. Any ideas? Thanks.

• Ubuntu 11.10 won't let me login; it kicks me back to login screen

  - by zlyfire

  I was just copying files from my external HDD to my .wine directory, when I noticed the place where the launchers are (Unity desktop) was getting fuzzy and holding onto graphics from the things in the location prior(i have it autohide when a window covers it). I assumed it was just RAM problem, so I canceled the copying, since it wasn't actually important. The glitch remained, and so did another; very slow response time. The mouse moved just fine, but windows were waiting about a minute after I hit the x button to close or even switch active window. Once again, I blamed RAM (only have 2 GBs) so I restarted. Usually, it autologs me into my account, since I'm the only user, but this time it presented me with the login screen. I thought it odd, but tried to log in. A black screen with some text pops up (assuming terminal screen) for half a second then kicks me back to the login screen. I tried the guest account and no luck. I went into terminal (alt+ctrl+f1) and logged in and it worked. I deleted .Xauthority, made new account, and even rebooted quite a few times, all to no avail. Anyone have an idea?

• I still can't figure out how to program!

  - by Mark K.

  Please help! I've read lots of programming books for various languages, Java, Python, C, etc. I understand and know all of the basics of the languages and I understand algorithms and data structures. (Equivilant of say 2 years of CompSci classes) BUT, I still can't figure how to write a program that does anything useful. All of the programming books show you how to write the language, but NOT how to use it! The programming examples are all very basic like build a card catalog for a library or a simple game or use algorithms etc... They dont't show you how to develop complex programs that actually do anything useful! I've looked a open-source programs on sourceforge, but they don't make much sense to me. There are hundreds of files in each program & thousands of lines of code. But how do I learn how to do this? There's nothing in any book I can buy on Amazon that will give me the tools to write any of these programs. How do you go from reading Intro to Java or Programming Python, or C Programming Language, etc.. to actually being able to say, I have an idea for X Program.. this is how I go about developing it? It seems like there is so much more involved in writing a program than you can learn in a book or from a class. I feel like there is someth Can anyone put me on the right track?

• How do I estimate the number of RSS subscribers?

  - by Robert Kosara

  I'm running a website, and would like to get a better idea how many subscribers I have. I can check the number of subscribers on Google Reader for my two feeds (RSS and Atom). I also have access to my server logs, so I sometimes collect all the IP addresses that access the feeds over a month or so and do a uniq. Is that an accurate way of doing this? Are there other feed aggregators that I need to take into account? Any pitfalls when just going by IP address? I've also thought about embedding an image in the feeds to get a better count. But do all feed readers load images automatically?

• Why is the "file" command get confused on .py files?

  - by pythonic metaphor

  I have several python modules that I've written. Randomly, I used file on this directory, and I was really surprised by what I saw. Here's the resulting count of what it thought the files were: 1 ASCII Java program text, with very long lines 1 a /bin/env python script text executable 1 a python script text executable 2 ASCII C++ program text 4 ASCII English text 18 ASCII Java program text That's strange! Any idea what's going on or why it seems to think python modules are very often java files? I'm using CentOS 5.2.

• Permission denied on network share

  - by Philipp

  i have a Windows 8 host system running a virtual(hyper-v) Debian6 client with an lamp environment. My development environment runs under Windows and I mapped the folder with my php files to a network drive so Apache has access to them.(mount.cifs //pc/share /var/share/) This far no problems - I see my app on windows in the browser. The problem is, I can't write stuff in php to the share folder - everytime i got a permission denied message in my error logs. For testing purpose i tried to change the directory permissions of /var/share with chmod -R 777 /var/share without success. Now Iam a little bit stumped.. has anyone an idea how to solve this?

• How can I get GrowlTunes to Launch whenever iTunes Launches?

  - by Orion751

  I think I would be able to do this by modifying iTunes' launch services. Any idea how to go about that? Would editing its info.plist file in a manner similar to below do what I'm looking for? <keyLSOpenApplication</key <string?</string EDIT: Would http://developer.apple.com/library/mac/#documentation/Carbon/Reference/LaunchServicesReference/Reference/reference.html%23//apple_ref/c/func/LSOpenApplication provide any hints? EDIT2: Last.fm's official Mac Scrobbler (http://www.last.fm/download) is a perfect example of the functionality that I'm looking for.

• How can I make this arcade-highscore game more fun/interesting?

  - by j-a

  I'm having difficulties getting the fun factor into this iPhone game, and I am looking for some ideas or advice. I was asked to generalize the question a bit. What are some techniques for arcade highscore games that can be applied to this game in order to: Make each second of the game fun and challenging, from the first second to the end of the game. Regardless of skill level. Make the player want to try again and again to beat the high score. Briefly about the game: you aim using your finger and pull the bow chord and release by lifting your finger. That part feels quite nice how the bow interacts with the finger. The game idea: hearts fall down and you get 1 pt for each heart you shoot. You start with a few arrows and every now and then a bag of arrow comes down which - if you hit it, you get more arrows. Once your out of arrows the game is over. So it is all about beating your previous high score or your friends high scores. Unfortunately I don't find it that fun. Thankful for any ideas/suggestions/thoughts on how to make it more fun/interesting.

• vsftpd chroot_local_user does nothing

  - by Reinderien

  Hello all. I'm setting up a vsftpd server on: Linux 2.6.32-26-server #48-Ubuntu SMP Wed Nov 24 10:28:32 UTC 2010 x86_64 GNU/Linux When I set chroot_local_user=YES, there is no effect (I can still see / when I log in). There is nothing in syslog or /var/log/vsftpd.log to indicate what's wrong. I know that I'm editing the right conf file and that other settings do come into effect when I restart the daemon, because these work: ssl_enable=YES force_local_data_ssl=YES force_local_logins_ssl=YES Any idea what's wrong? Thanks.

• Why S3 website redirect location is not followed by CloudFront?

  - by ychaze

  I have a website hosted on Amazon S3. It is the new version of an old website hosted on WordPress. I have set up some files with the metadata Website Redirect Locationto handle old location and redirect them to the new website pages. For example: I had http://www.mysite.com/solution that I want to redirect to http://mysite.s3-website-us-east-1.amazonaws.com/product.html So I created an empty file named solutioninside my bucket with the correct metadata: Website Redirect Location= /product.html The S3 redirect metadata is equivalent to a 301 Moved Permanentlythat is great for SEO. This works great when accessing the URL directly from S3 domain. I have also set up a CloudFront distribution based on the website bucket. And when I try to access through my distribution, the redirect does not work, ie: http://xxxx123.cloudfront.net/solution does not redirect but download the empty file instead. So my question is how to keep the redirection through the CloudFront distribution ? Or any idea on how to handle the redirection without deteriorate SEO ? Thanks

• Kubuntu 11.10 Lot of Networking problems

  - by Cobraone

  Since I upgrade to 11.10 I have a lot of problems with KDE. First of all there are problems in configuring a static IP address. Just to explain @home I have a normal fiber ADSL and I use a DHCP. When I go to a customer I must insert a static IP address. With ifconfig everything seems ok but there is something wrong in searching DNS names. (I have installed Ubuntu and was going ok again). Now I Have reinstalled again Kubuntu 11.10 and I have the same problem in addition today I have discovered that if I connect to a network in another customer office the desktop freezes and I could only switch between windows with alt+tab. No FN key or right click to open run command works. So i unplugged network (configuration is just DHCP here) and tried on another position in office. It was the same. My Laptop freezes when connected, a fedora 14 of a friend works. So I decided to connect my Galaxy S II as USB network device. Everything is ok for like 3 minutes. When I noticed a little loss of signal again the desktop freezes and i must work (like now) just switching between windows with alt+tab). Additional information: Unplugging network or restarting it via Konsole does not not solve the freezing problem. Every time I must open a console and reboot. Any idea of what tests to do ? Just a recommendation: If I must post here logs or something else please guide me. I use Linux since Ubuntu 9 but I am not an "expert".

• Detecting hardware and installing drivers in Windows XP

  - by JL.

  I have on my desk a computer that I am reinstalling. I have just completed the Windows XP install , which is professional service pack 3. I have also installed an AV package. Now it is time to install the audio and display drivers. Windows Update does not detect the Display card, and neither the audio device. I really have no idea what devices are present in this system, and I am thinking of opening the case, and reading some IDs from the cards themselves. Before I do this, is there not some kind of tool that can automatically detect hardware and install drivers automatically. If not then at least tell me what devices are present, with some real descriptions, so I can search for drivers.

• Can't boot after compiling 3.1 kernel, can only get to terminal

  - by olssy

  Long story short: I tried compiling kernel 3.1 on Ubuntu 11.10 at the same time I had an update waiting for a reboot. Computer would boot to a black screen and would hang there. Ended up installing 11.10 on top of old install with a Live CD. Now I had a purple screen on bootup but it would end up booting. Realized Grub was the problem and tried some stuff but nothing worked. I ended up trying to install propriety ATI video drivers and since that nothing has worked, no grub menu(purple screen) and when it boots into the kernel it ends up hanging, I can sometimes get a terminal up with alt-fx. I have tried removing the ati drivers with the ati script, purging my fglrx driver, reconfiguring my xconf.org and following any tutorial I can find about fixing a broken graphics driver, but to no avail. I've gotten to a point were it seems that the ati propriety drivers are correctly loaded but it still has no grub boot menu and won't boot into Ubuntu. I've chased down my logs and this line is from kern.log: unity-greeter[3269]: segfault at 0 ip b7245cbbsp bf9d3900 error 4 in libgio-2.0.so.0.3000.0[b71ad000+142000] That line leads me to believe I don'T have the correct libgio-2 librairy on my system but have no idea how to find out what package has the correct version... My xorg.conf has no errors and seems to imply the fglrxdrm module got loaded correctly. Would be a bit complicated pasting the whole file here but if it would help I'll post it. LAstly, running fglrxinfo give me: Error: Unable yo open display (null) Any help or link to another tutorial would be appreciated. Thanks.

• I/O redirection using cygwin and mingw

  - by KLee1

  I have written a program in C and have compiled it using MinGW. When I try to run that program in Cygwin, it seems to behave normally (i.e. prints correct output etc.) However, I'm trying to pipe output to a program so that I can parse information from the program's output. However, the piping does not seem to be working in that I am not getting any input into the second program. I have confirmed this by using the following commands: This command seems to work fine: ./prog Performing this command returns nothing: ./prog | cat This command verifies the first: ./prog | wc Which returns: 0 0 0 I know that the script (including the piping from the program) works perfectly fine in an all Linux environment. Does anyone have any idea for why the piping isn't working in Cygwin? Thanks!

• Super user in LDAP?

  - by John8894

  I am running 10 Linux machines that is doing different types of work. The machines are configured to use LDAP authentication so when one user is configured in slapd he can login on all the machines. To make maintenance easier i want to create a root account in slapd so i can use this instead of the local root accounts when installing applications etc. but i am not sure on how to do this. Is it enough to create a user with the name root and gid/uid 0? should the local root be disabled somehow? I am fully aware that this is normally not a good idea from a security perspective, but as mentioned before this is a special case.

• Is Ruby on Rails supposed to have a steep learning curve or is it just me?

  - by Anita

  I'm a self-taught programmer. I've been learning RoR since October with varying intensity (sometimes all day, sometimes nothing for several weeks). Before that I knew only Java, but knew it pretty well. I've heard so much hype about RoR and how it's supposed to make you happy, productive, etc. So far it's only made me frustrated. I learned it out of the Agile book, and I suspect part of the difficulty might have to do with my not knowing JavaScript and CSS, and having only a shaky grasp of databases and HTML. But apparently it took me much longer to complete the project in the Agile book than other people, and I still don't remember much of it. There are some things about Rails that I just can't seem to get, e.g. when to use symbols and when NOT to, or how dynamic methods are called. Recently I was given a small Rails assignment where I'm asked to make a small change to the interface. It's taken me around 25 hours and although I've made some progress in understanding the code, I still have no idea how to proceed. I can't even ask Stack Overflow because there is so much code I'll have to provide to give context. So my question is in the title: is RoR supposed to take a long time to learn or am I just slow? Can it be that I've been learning from the wrong book? My learning style is such that I either understand nothing or understand everything, if that makes sense. Thanks!

• No External Sound

  - by Walter

  I have ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal did alsamixer seems to recognize my soundcard, though the driver is not listed in system - admin -hardware drivers, the only driver listed is my graphics card. I have tried several forums and it seems no one is interested in responding to sound issues. Here's hoping it is different here.

• Safety concerns on allowing connections to MySQL with no password on localhost?

  - by ÉricO

  In the case of a Linux system, is there any security concern to let MySQL users with standard privileges (that is, not the root users) connect to the database with no password from localhost? I think that enforcing a password even for localhost can add a layer of protection, since, with no password the database access would be compromised if the SSH access is itself compromised. Considering that, would it be less safe to allow no password connection to MySQL than having the same password for SSH and for MySQL? I don't know if that is to be taken into account, but we also use phpMyAdmin to let users administrate their own database. I am asking because I kinda dislike having to put our database passwords unencrypted in the source or configuration files of our applications, where they can easily be leaked unintentionally. Since our servers are configured to run our applications as the Linux user the application belongs to, I was considering allowing no password from localhost as a simple solution. So, would that be a very bad idea or not?

• How to prevent overlapping of gunshot sounds when using fast-firing weapons

  - by G3tinmybelly

  So I am now trying to find sounds for my guns but when I grab a gun sound effect and play it in my game a lot of the sounds are either terrible sounding or have this horrible echoing effect because as a gun shoots sometimes the previous sound is playing still. public void shoot(float x, float y, float direction){ if(empty){ PlayHUD.message = "No more bullets!"; return; } if(reloading){ return; } if(System.currentTimeMillis() - lastShot < fireRate){ //AssetsLoader.lmgSound.stop(); return; } float dx = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); float dx1 = (float) (-13 * Math.cos(direction) + 75 * Math.sin(direction)); float dy1 = (float) (-14 * -Math.sin(direction) + 75 * Math.cos(direction)); PlayState.effects.add(new MuzzleFlashEffect(x + dx1, y + dy1, (float) Math.toDegrees(-direction))); PlayState.projectiles.add(new Bullet(this, x + dx, y + dy, (float) (direction + (Math.toRadians(MathUtils.random(-accuracy, accuracy)))))); if(OptionState.soundOn){ AssetsLoader.lmgSound.play(OptionState.volume); } bulletsInClip--; lastShot = System.currentTimeMillis(); } Here is the code for where the sound plays. Every time this method is called the sound is called but it happens so often in this case that there is this terrible echoing. Any idea on how to fix this?

• What is the best method to determine an account through DNS A record configuration?

  - by Matt

  I apologize if my description of the problem is unclear. I am working for an online CMS that allows external domains to be used similar to Tumblr or Flavors.me. I noticed both of these services simply require you to add an A record to your domain's DNS. When trying this, I added an A record for a blank name and "www" both leading to my webserver's IP. While this successfully routes to my server, it doesn't retain the used domain. This leaves me without any idea of what account they're attempting to reach at the application layer. I'm using nginx as my webserver. I have changed all the nameservers for a domain before, and that works properly, however that causes complications with other issues such as mail and isn't feasible on a scaled solution. What should I be doing here? Is the A record the correct method of accomplishing this? How are sites like Tumblr and Flavors.me determining which account is being referenced by the domain?

• How to fix Sketchup in Wine when tool starts, but displays empty workspace?

  - by Chaos_99

  I've installed wine 1.6 and winetricks in an Linux Mint 15 system, then downloaded the latest Sketchup2013 'Make' Windows-Installer and installed through wine. I've prepared the wine environment with starting as WINEARCH=win32, installed corefonts and ie8 and enabled the override for the 'riched20' libraries. (I've no idea what the last bit does, but it was advised in some guides.) I've also tried without these steps. Only the win32 seems to make a difference, as the installer will complain about not finding SP2 otherwise. Sketchup is installed successfully and starts, but displays an empty viewport. The program is responsive and everything works, it's just that you can't see anything. I don't get any OpenGL error and the registry entries seem fine, according to the OpenGL issue workarounds floating around the net. I still think it has something to do with OpenGL not working properly, maybe not in the wine environment, but in the linux system? I'm running on a Lenovo W520 with Nvida/Intel hybrid cards, but only the NVida card is active and the properitary nvidia (319) drivers are installed. GLXGears runs fine, but clamps at 2x the refresh rate. glxinfo outputs direct rendering: Yes server glx vendor string: NVIDIA Corporation server glx version string: 1.4 I'm willing to try any linux or wine OpenGL tests to narrow down the problem, if you can offer any advise on what to use.
