• How to change hybrid disk to basic disk in windows 7?

  - by Marco

  I created a partition E and then deleted the partition. After that I extended my partition C (where OS was installed) to take the space. My partition C became hybrid drive. My hp notebook does not have DVD rom and the notebook only came with an recovery image (I also have a paragon disc image). My computer has some problems now and I want to recover it by either the factory format or the paragon disc image. However, none of them works. I know it is because my disc has become hybrid disk. My question is how to fix the dynamic disk problem?

• sharing life experience

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter). I have send that question to stackoverflow before when I am at first year. Now, I want to construct webpage to guide fresh students by giving advise of yours and mines.Maybe, you wonder Why I want to construct webpage , I just want help the other student. I am giving a link to that question < http://stackoverflow.com/questions/3389465/how-should-i-study-programming-languagess If you have other advice, feel free. EDIT: This web cite, I think , is constructed to share member's life experience and also I know these experiences is valuable . So I have no right to want your opinion, But I want your opinion / experience even if you think it is not so helpful to other

• Hosting files with support for file tagging / keywords

  - by Zev Chonoles

  I have a large (approx. 25GB) collection of files I would like to host online for people to view or download. I have a spare computer I can use as a dedicated server for these files. I'm looking for a method of, or piece of software for, hosting my files where I can assign tags or keywords to the files, and people viewing my files online can search the collection via the tags. By way of approximate solutions I've found so far, I see that there is software such as Collectorz.com or Readerware for creating databases of one's books / music / movies, and these databases can be searched by tags or keywords, and the databases can be made available and searchable online; this would suit my purposes except that my files are not necessarily books, music, or movies, and I want the files themselves accessible online, not a database describing my files. A commercially-available solution like the ones above would be acceptable, but I'd prefer to have the whole setup under my control (i.e. I'd like to either implement it by hand, or use commercial software that doesn't rely on using the company's servers, paying them a continued fee, etc.). The current extent of my internet experience is designing a few Google Sites, so I know there's a fair chance I won't understand the answers I receive, but I'm always happy to have a summer project :)

• Why does OS X automatically logout my user?

  - by MBA_fv

  I have a new MacBook Air set up with filevault. In the Security preference pane I have "Require password 1 hour after sleep or screen saver begins" enabled, but the "Logout after 60 minutes of inactivity" is disabled. When I leave the computer on overnight I manually lock the screen (from the Keychain status menu bar, which I enabled via the Keychain Access preferences). Alas, in the morning I find that instead of a locked screen I see the login window, after my user was logged out with all applications terminated... (e.g. Firefox thinks it previously crashed when I launch it). This type of behavior only started after I enabled Filevault. Why is this happening? How do I prevent such auto-logout?

• Downloading file from FTP using cURL

  - by Josiah

  I'm trying to use a cURL command to download a file from an FTP server to a local drive on my computer. I've tried curl "ftp://myftpsite" --user name:password -Q "CWD /users/myfolder/" -O "myfile.raw" But it returns an error that says: curl: Remote file name has no length! curl: try 'curl --help' or 'curl --manual' for more information curl: (6) Could not resolve host: myfile.raw; No data record of requested type I've tried some other methods, but nothing seems to work. Also, I'm not quite sure how to specify which folder I want the file to be downloaded to. How would I do that?

• How to setup wireless radio to network using 2 nics?

  - by CptanPanic

  I am having problems setting up this network, hopefully someone can help me. Laptop <- Wireless Radio <- ... - Wireless Radio <- CPU1( NIC1,NIC2) <- SWITCH <- CPU2 I have a computer with 2 NICs (CPU1). One goes to a wireless radio that connects to a wireless laptop, the other NIC goes to network switch. I can't connect Wireless Radio to switch due to space constraints. All the machines and radios are on same network addresses. I tried using Window's Bridge network which did allow Laptop to reach CPU2, but not CPU1. What is the way to get this to work so all the computers can talk to each other?

• Why can't I boot from portable HD?

  - by user11239

  I've been trying to get Ubuntu 10.04-LTS 32-bit desktop installed onto a 250GB FreeAgent Go drive from Seagate. I've been able to install onto a USB flash drive and boot successfully from this. I have installed Ubuntu onto the jump drive using Universal USB Installer, and this was a total success in terms of getting Ubuntu to run off a flash drive. I was unable to accomplish this with the portable HDD. I then, following instructions, attempted to install the OS onto the HDD once booted up from the flash drive. After installing the OS on the HDD, the computer would simply not load the OS when the HDD medium was selected for booting from. However, as there is no System-> Preferences-> Removable Drives and Media I could not complete this step. Is this vital? How do I do this under Ubuntu 10.04? I have formmated the MBR on the HDD and repeated the above, still with no success. I have also browsed some forums that mention there may be something related to spin-up speeds, but nothing explained in detail the issue or how to solve it, and I'm not familiar enough with system booting to understand if this could be an issue. Basically, what I'm trying to do is get Ubuntu to boot off the HDD, I've attempted several things, and the result is, after selecting the HDD from BIOS, the OS never starts booting (after waiting upwards of ten minutes). I just have a white cursor blinking. I can always get it to boot from the jump drive. Related question

• My laptop can connect to every wireless network except fios

  - by going crazy

  I have always been able to connect to every wireless router secured or unsecured wep or wpa. I had Fios installed and could not connect. Verizon suggested it was my computer and gave me an outside wirless drive to use, it worked. I got rid of fios and went back to comcast and threw out the drive, but now 2 years later, I am sitting at my friends house haveing the same problem. My tech savy friend told me it is a firewall setting or something in my antivirus software, but I disabled them both and still nothing works........Funny it is only FIOS

• Why can't I create a Windows backup on my secondary disk?

  - by Brian Sullivan

  I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

• View scheduled recordings remotely

  - by Scott

  I have one computer which is equipped with a TV tuner card. The Recorded TV folder is shared so that other computers on the network can watch recordings. Now that I am upgrading my computers to Windows 7, they have Media Center, which makes for a nicer viewing experience than a Windows Explorer folder view. I have set up Media Center on my laptop to considering the Recorded TV folder on the tuner-equipped PC as an extended library location, so now I can view all the recordings from within Media Center on the laptop. To make this experience even better, is there a way to view the list of scheduled recordings on the tuner-equipped PC from within Media Center on my laptop?

• To sell or give for free

  - by QAH

  Hello everyone! I am currently making a game that I was originally planning to sell. It is a simple 2D arcade style game for the PC. I've seen many indie games become popular and generate revenue from advertisements, but the game itself remains free. I need some advice on whether or not I should sell my game, release it for free with advertisements, or ask for donations and keep the game free. I feel that my game is fun, but of course the graphics aren't tip top because I am a programmer, not an artist. I just take screenshots of 3D models I get from Turbosquid and crop around it to make a sprite. Also, and I could be very wrong about this, it seems that there are more legal issues surrounding selling a game than making it free and generating revenue from advertisement, or asking for donations. If I am wrong, someone please correct me. Also, I am very interested in generating some revenue for my work, but that isn't at the very top of my list. I am in my last year of high school, soon to be going to college, and I am going to major in computer science/software engineering. So I am trying to gain some preliminary experience at home by coding stuff every day. One way of getting this experience is by making this game. So what do you think? What route should I take? What has worked well with other indie games? Thanks in advance.

• backuppc - how to backup remote (over the internet) clients?

  - by Scott

  I am testing out backuppc, which works great so far backing up windows clients on a LAN via SMB (no backup client/agent required). However I have quite a few laptops and desktops that are in various remote locations - some of which move around. I need some way to have that remote computer create an outgoing connection for backup purposes (Windows XP/7). I know backuppc supports smb, rsync and 'tar', but I believe these are all connections going from the server TO the client. SO, I either need a way to vpn the client on a timed basis, or it would be a lot better if the client could some how connect to the server (ssh?) and initiate it's own backup somehow (rsync?). Of course this all needs to be pre-installed by me and require no maintenance by the end user, no dialogs on their side. What do you think?

• RDP locks up login, doesn't unlock on Windows

  - by private_meta

  From time to time, my system, when I try to login TRHOUGH or AFTER a remote connection, locks up the login session. I can't login anymore, the screen turns black (the monitor is still active, the image is black). Especially in the recent case, the system did not come back from the lock-up, and I had to reset the computer. Any idea what might be the issue here? More information: Both Computers are Windows 7, The RDP Server has a wired connection, the Client has either Wireless or Wired. The network card involved on the server is a "Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)" card built-in on an ASRock Mainboard. I'm using either local LAN or internet connection through NAT/Router.

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

• Cannot write, format, nor erase flash drive

  - by Baruch

  I have a 4gig flash drive, which I can read from but not write on, erase, nor format in any computer (tried in 7 different computers including xp, vista, and win7). I want to erase all the data inside because it is useless. Once I erase something, it erases it and gives me an error that it can't find the file. Once I refresh the folder, the file comes back. I tried holding Shift + Del. I also tried to use the command to format it in safe mode, but it says "access denied". I don't have a write protection button or whatever it is on my flash drive. It's just a simple small 4 gig one.

• How do I use an API?

  - by GRardB

  Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

• Is writing recursive functions hard for you?

  - by null

  I'm taking a computer science course now. I feel it is so hard compared to my polytechnic IT course. I can't understand recursive methods well. How do you manage to get your brain to understand it? When the recursive method returns back, my brain can not trace it nicely. Is there a better way to understand recursion? How do you start learning it? Is it normal that feel that it is very hard at then beginning? Look at the example, I'm very surprised how can I write this if it appears in exam. public class Permute { public static void main(String[] args) { new Permute().printPerms(3); } boolean[] used; int max; public void printPerms(int size) { used = new boolean[size]; max = size; for (int i = 0; i < size; i++) { used[i] = false; } perms(size, ""); } public void perms(int remaining, String res) { if (remaining == 0) { System.out.println(res); } else { for (int i = 0; i < max; i++) { if (!(used[i])) { used[i] = true; perms(remaining - 1, res + " " + i); used[i] = false; } } } } }

• Map specific keys in emacs - Ubuntu

  - by Josh

  On my Mac, I have remapped the capslock key to be another Ctrl, and the key to the right of control to be M (meta?). It was real easy, the capslock was in sys prefs, and the M key was a pref in terminal. I cannot figure out how to do it on my Ubuntu 10.10 computer though. There was no remap capslock that I could find under any of the three keyboard pref menu items, and there are no prefs under the terminal that I can find. Can someone advise? I want the windows key on the keyboard to be M, if that matters. tl;dr; Ubuntu 10.10: Map capslock as Ctrl and Windows key as Meta (emacs) Thanks! EDIT: Found Capslock under System - Prefs - Keyboard - Layouts - USA - Options - Ctrl Key Position - Make CapsLock an additional Ctrl

• Is it possible to code on two different computers simultaneously?

  - by Muhammad

  I want to work with another programmer and I want the source code to be live in real-time on both of our screens. Is this possible on the Mac OS x or Linux? We're going to be using OS X but occasionally we might need to add an Ubuntu computer too. Is there a way I can do this using ssh, any shell based program, or even a good GUI? I thought Coda might be capable of this but it's not really working. Anyone ever do this? I'm not look for a git/svn/or any other version control system. This is more of a live coding session. :)

• Windows 7: This notification icon is currently not active

  - by icelava

  Some time this week, without any major change done to one of my x64 Windows 7 computers, the Media eject icon goes missing in the systray taskbar area. When I attempt to reset the notification settings, i see this "This notification icon is currently not active" info warning Initially KB945011 managed to restore the icon after a reboot. But now it appears to have disappeared again. It seems to have disappeared (cannot really confirm) after I unlock the physical logon session (which was previously rerouted to a virtual Remote Desktop session). Anybody have knowledge on possible causes to this missing behaviour? UPDATE 1 Feb 11 It seems that happens often when I remote desktop to the computer, I see it from the remote screen, but when i unlock the screen physically, it disappears. It would reappear when I connect to remote desktop again. Hmmmmm.

• Any examples of fair mmo games with quick completion

  - by Keith Player

  I'm looking for some example games for inspiration that allow from 10 to a large number of players at a time and can be completed in 10 to 30 minutes. I'm looking for something that would have extremely low bandwidth and not be dependent on chance or luck (i.e one player can't gain an unfair advantage because the computer put them in a better position). Realized on the way home that more clarifications might have been helpful. I'm looking to develop a pay-to-play competition that would allow a large number of players to compete in a relatively short period of time. One way would be to have an mmo that can be completed in 30 minutes, another way would be if you could have 10 person games that finish in under 5 minutes and then have the winners compete against each other until a winner is decided. I'm interested in any genre that would make for a fun/interesting game that doesn't depend on luck, so all players should have the same choice/availability of activities/resources and follow the same rules. Some possible games that could possibly be modified into what I want, would be bztanks (too easy to create a bot), diplomacy (takes too long), risk, some chess like game. I was just wondering if there are other game types to the ones I have been considering.

• How to load previous kernel via ssh?

  - by Aamir

  I work remotely on my work computer. I am also the root of the workstation that I am sharing with my colleague. Yesterday, I upgraded the kernel to 2.6.31-17 when asked by the update manager but refrained from restarting because I knew my NVIDIA and several other kernel modules wouldn't work. Unfortunately my colleague who is a linux noob restarted the machine and here I am :( I am thinking of changing the symlinks /initrd.img and /vmlinuz to the previous kernel image and use kexec. Please tell some better way to load the 2.6.31-16 release of kernel from ssh and not the grub boot menu. I am using Ubuntu Karmic.
