How does a collision engine work?

- by JXPheonix

Original question: Click me How exactly does a collision engine work? This is an extremely broad question. What code keeps things bouncing against each other, what code makes the player walk into a wall instead of walk through the wall? How does the code constantly refresh the players position and objects position to keep gravity and collision working as it should? If you don't know what a collision engine is, basically it's generally used in platform games to make the player acutally hit walls and the like. There's the 2D type and the 3D type, but they all accomplish the same thing: collision. So, what keeps a collision engine ticking?

Logging in over and over again. How to fix this?

- by romeovs

Ok, I messed up. I installed ubuntu 11.10, installed awesome wm and removed unity, to have something to fall back on, I also installed gnome-session-fallback. I was messing around and did the following, because the awesome wiki told me to: gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop False # Still disable the buggy Nautilus desktop thing gconftool-2 --type string --set /desktop/gnome/session/required_components/windowmanager awesome # sets awesome as wm Now here's what's wrong: I can start up decently, and then I get into a login window (that of gnome-session-fallback). I enter my username, select the preferred window manager (awesome in my case) and enter my password. It accepts these, but then hold for a second and just opens the login window again, in effect preventing me from actually logging in. I also tried gconftool-2 --unset (from the tty) on these settings, but that didn't work either. What can I do to revert the gconftool-2 settings to something that should work? I tried apt-get purging gnome-session-fallback and lightdm, and then installing them again, but that didn't work.

Access denied 403 errors after migrating my site

- by AgA

I've recently migrated my Joomla site from one shared hosting to another with Hostgator. GWT notified me about many 403 access denied pages. I've checked with Firebug too, and even though browser is displaying full page correctly but http return is 403. I've checked the home page but it's correctly returing 200 response. The same is shown by Fetch as Google in GWT(pasted this in the bottom). The site is 3 years old and I regularly do such migrations. I've copied the files and database "AS IS". I've even cleared all the caches but no luck. There is only one change: previously the site was primary domain but now it's add-on one. What could be the issue? This is how Googlebot fetched the page.

NHibernate Session Load vs Get when using Table per Hierarchy. Always use ISession.Get<T> for TPH to work.

- by Rohit Gupta

Originally posted on: http://geekswithblogs.net/rgupta/archive/2014/06/01/nhibernate-session-load-vs-get-when-using-table-per-hierarchy.aspxNHibernate ISession has two methods on it : Load and Get. Load allows the entity to be loaded lazily, meaning the actual call to the database is made only when properties on the entity being loaded is first accessed. Additionally, if the entity has already been loaded into NHibernate Cache, then the entity is loaded directly from the cache instead of querying the underlying database. ISession.Get<T> instead makes the call to the database, every time it is invoked. With this background, it is obvious that we would prefer ISession.Load<T> over ISession.Get<T> most of the times for performance reasons to avoid making the expensive call to the database. let us consider the impact of using ISession.Load<T> when we are using the Table per Hierarchy implementation of NHibernate. Thus we have base class/ table Animal, there is a derived class named Snake with the Discriminator column being Type which in this case is “Snake”. If we load This Snake entity using the Repository for Animal, we would have a entity loaded, as shown below: public T GetByKey(object key, bool lazy = false) { if (lazy) return CurrentSession.Load<T>(key); return CurrentSession.Get<T>(key); } var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), true); var snake = animal as Snake; snake is null As you can see that the animal entity retrieved from the database cannot be cast to Snake even though the entity is actually a snake. The reason being ISession.Load prevents the entity to be cast to Snake and will throw the following exception: System.InvalidCastException : Message=Unable to cast object of type 'TPHAnimalProxy' to type 'NHibernateChecker.Model.Snake'. Thus we can see that if we lazy load the entity using ISession.Load<TPHAnimal> then we get a TPHAnimalProxy and not a snake. =============================================================== However if do not lazy load the same cast works perfectly fine, this is since we are loading the entity from database and the entity being loaded is not a proxy. Thus the following code does not throw any exceptions, infact the snake variable is not null: var tRepo = new NHibernateReadWriteRepository<TPHAnimal>(); var animal = tRepo.GetByKey(new Guid("602DAB56-D1BD-4ECC-B4BB-1C14BF87F47B"), false); var snake = animal as Snake; if (snake == null) { var snake22 = (Snake) animal; }

How does AuthzSVNAccessFile work?

- by grigy

I have set up an SVN repo with WebDAV access. For some reason it does not let checkout. Here is my httpd.conf part: <Location /svn> DAV svn SVNParentPath /home/svn/repositories AuthzSVNAccessFile /home/svn/dav_svn.authz Satisfy Any Require valid-user AuthType Basic AuthName "Subversion Repository" AuthUserFile /home/svn/dav_svn.passwd </Location> I have two repositories named "first" and "second" and the content of dav_svn.authz is: [first:/] doe = rw * = r [second:/] doe = rw grig = rw * = r When I'm trying to checkout the second with user doe, I get this in error_log: user doe: authentication failure for "/svn/second": Password Mismatch In order to understand what can be the problem I would like to better understand how the AuthzSVNAccessFile is supposed to work.

Chrome trims the last <li> element in a row [closed]

- by Paul

Ok guys, I give up. Here's the code I'm struggling with: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>Blah</title> <style type="text/css"> #container { margin: 0 auto; width: 350px; border: 1px solid #ccc; } ul { list-style-type: none; margin: 0; padding: 0; text-align: center; } ul li { display: inline; padding: 5px; margin: 0 1px; background-color: lime; line-height: 2em; /* border: 1px solid red; */ } </style> </head> <body> <div id="container"> <ul> <li>Element A</li> <li>Element B</li> <li>Element C</li> <li>Element D</li> <li>Element E</li> <li>Element F</li> </ul> </div> </body> </html> Why the heck does Chrome trim the right side of "Element D" (even though there is enough space to display whole item), while Firefox and even Internet Explorer render this code properly? It becomes more visible when we apply the commented border. In other words, is there a way to tell the browser that I want every single <li> element to be autonomic, and thus to move it to the next row if it doesn't fit entirely in the previous one? Can't wait to see the solution, thanks in advance.

How to make the emacs not to pop up a window when using tab-completion?

When I use the emacs shell mode or in gdb, when I type double tab, the emacs pop up a new window which always cover an existed window. While in terminal, when I type double tab, to complete a directory, the terminal just print all the candidates in the same window. Can I make the emacs not to pop up a new window when I use this feature? edit this is I wanna do , but it's wrong, can somebody fix this? ;remove annoying poped-up windows (defun rm-popup-window () (other-window) (kill-this-buffer) (other-window) ) (global-set-key [C-'] 'rm-popup-window);

Many sources of movement in an entity system

- by Sticky

I'm fairly new to the idea of entity systems, having read a bunch of stuff (most usefully, this great blog and this answer). Though I'm having a little trouble understanding how something as simple as being able to manipualate the position of an object by an undefined number of sources. That is, I have my entity, which has a position component. I then have some event in the game which tells this entity to move a given distance, in a given time. These events can happen at any time, and will have different values for position and time. The result is that they'd be compounded together. In a traditional OO solution, I'd have some sort of MoveBy class, that contains the distance/time, and an array of those inside my game object class. Each frame, I'd iterate through all the MoveBy, and apply it to the position. If a MoveBy has reached its finish time, remove it from the array. With the entity system, I'm a little confused as how I should replicate this sort of behavior. If there were just one of these at a time, instead of being able to compound them together, it'd be fairly straightforward (I believe) and look something like this: PositionComponent containing x, y MoveByComponent containing x, y, time Entity which has both a PositionComponent and a MoveByComponent MoveBySystem that looks for an entity with both these components, and adds the value of MoveByComponent to the PositionComponent. When the time is reached, it removes the component from that entity. I'm a bit confused as to how I'd do the same thing with many move by's. My initial thoughts are that I would have: PositionComponent, MoveByComponent the same as above MoveByCollectionComponent which contains an array of MoveByComponents MoveByCollectionSystem that looks for an entity with a PositionComponent and a MoveByCollectionComponent, iterating through the MoveByComponents inside it, applying/removing as necessary. I guess this is a more general problem, of having many of the same component, and wanting a corresponding system to act on each one. My entities contain their components inside a hash of component type - component, so strictly have only 1 component of a particular type per entity. Is this the right way to be looking at this? Should an entity only ever have one component of a given type at all times?

Ubuntu 64bit Black Screen on Minecraft

- by Signify

I have tried posting on the forums, but I really need help (I'm a server admin and really don't want to have to switch to Windows just to run Minecraft). Anyhow, I originally was running openjdk6 as I was told that 7 was unstable and was getting periodical lag spikes while walking (at least once every 3 seconds the screen would freeze for a tenth of a second). After that, I attempted to install Sun's Java JDK7 (I couldn't get ahold of 6 without signing up for Oracle's newsletters). Upon attempting to run Minecraft, I got a black screen after logging in with this error message: 27 achievements 182 recipes Setting user: Thunder7102, -1618112820878091307 Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/noiro/.minecraft/bin/natives/liblwjgl.so: /home/noiro/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1939) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1864) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1825) at java.lang.Runtime.load0(Runtime.java:792) at java.lang.System.load(System.java:1059) at org.lwjgl.Sys$1.run(Sys.java:69) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.Sys.doLoadLibrary(Sys.java:65) at org.lwjgl.Sys.loadLibrary(Sys.java:81) at org.lwjgl.Sys.<clinit>(Sys.java:98) at org.lwjgl.opengl.Display.<clinit>(Display.java:132) at net.minecraft.client.Minecraft.a(SourceFile:184) at net.minecraft.client.Minecraft.run(SourceFile:657) at java.lang.Thread.run(Thread.java:722) Now, this got me fed up, so I tried to install a Windows 7 virtual machine through virtualbox, I gave it 256mb of graphics memory with 2D and 3D acceleration and 3GB of RAM. I installed Java JDK7 for Windows (which does work from experience on my other Windows 7 partition). Once again, a black screen after login. What the heck is going on guys?

Sales tracker that allows complex queries?

- by feklee

On a site, every click on a product should be registered by a sales tracker: price, type, etc. The sales tracker should provide an API so that complex queries can be performed, such as: Which products of a type "teapot" had a price below 20 EUR? Requirements: Recorded data should be available for querying no later than two hours after it has been recorded. For example, there are reports that Google Analytics may take up to 24h to update data. That is not acceptable. Querying doesn't need to be fast, but recording does (of course). Which sales tracker allows complex queries against collected data?

How to reduce tight coupling between two data sources

- by fstuijt

I'm having some trouble finding a proper solution to the following architecture problem. In our setting (sketched below) we have 2 data sources, where data source A is the primary source for items of type Foo. A secondary data source exists which can be used to retrieve additional information on a Foo; however this information does not always exist. Furthermore, data source A can be used to retrieve items of type Bar. However, each Bar refers to a Foo. The difficulty here is that each Bar should refer to a Foo which, if available, also contains the information as augmented by data source B. My question is: how to remove the tight coupling between data source A and B?

Do subdomains need to be defined through domain registrar?

- by Johnny

I have bought a new domain name from GoDaddy. Let's say it is abcd.com. On GoDaddy's DNS Managing page, I changed A(Host) part to @ = 74.125.232.215 which is www.google.co.uk's IP address. Now if I type www.abcd.com, it directly goes to www.google.co.uk. But if I type http://test.abcd.com, it cannot be loaded. Do I need to define every subdomain through GoDaddy? Is this how it works? P.S. Amazon EC2 directly generates a subdomain for users to reach their virtual PCs. It cannot be domain registrar dependant. P.S.2. Same question for using "www2" at the start of url.

Where can I download Microsoft VC80.CRT version 8.0.50608.0 ?

- by Leonel

Hi, I've just installed Microsoft Office Home and Student 2007 in Windows XP SP3 When trying to run MS word or any other office app (Excel, PowerPoint), I get the following message: this application has failed to start because the application configuration is incorrect This also happens with other applications, for instance, Acrobat Reader. A bit of Googling around this error message suggests that this might be due to a mismatch of library versions. In fact, most of the articles and forum messages I found mention a programmer writing an application in Visual C++ and sending it to someone else, who then runs into that error. This is hardly my case ! I looked into Office's files and the manifest file for Excel suggests that Office is trying to use Microsoft VC80.CRT version 8.0.50608.0. However, in my Windows System folder, I can only find the assemblies for 8.0.50727.762 My next step will be trying to find version 8.0.50608.0. How can I find and download it ?

Google won't display site

The title is quite long (Thermonuclear War Game Online: Thermonuclear War By Mark) and it has little (if any) competition. Have I been punished by Google for some reason, or is it something else? I have received zero hits from search engines. Can someone tell me why my site down't appear?

Text box select issue

- by Kent Boogaart

I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

LL(8) and left-recursion

- by Peregring-lk

I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

Windows 7 connect to Lion file sharing

- by Automaton

Trying to access my Mac from a Windows 7 computer, I fail with the infamous error 86 incorrect password. Now this appears to be a well-known problem with countless threads on the internet giving as many "solutions" as there are discussion threads about it (mostly ranging from installing third-party commercial samba servers, to switching to some other protocol, to compiling a plain-vanilla Samba installation - the latter which I will probably do when I give up this :) ) I am stubborn, and I believe there must be some problem here that can be solved or worked around, but there is surprisingly little detail about this problem. It appears to have something to do with a mismatch of authentication methods. Trying to run samba in debug mode: sudo /usr/sbin/smbd -debug -stdout gets me this output when trying to access it from Win 7 ... smb1_dispatch_one [smb_dispatch.cpp:377] dispatching SMB_COM_SESSION_SETUP_ANDX smb1_dispatch_session_setup [session_setup.cpp:261] FIXME erase existing sessions log_gss_error [gssapi_mechanism.cpp:97] gssapi: gss-code: Miscellaneous failure (see text) log_gss_error [gssapi_mechanism.cpp:113] gssapi: mech-code: unknown mech-code 22 for mech unknown What is the problem here, and how do I fix it?

I'm trying to make a basic space invaders clone in allegro 5, I've got my game set up, basic events and such, here is the code: #include <allegro5/allegro.h> #include <allegro5/allegro_image.h> #include <allegro5/allegro_primitives.h> #include <allegro5/allegro_font.h> #include <allegro5/allegro_ttf.h> #include "Entity.h" // GLOBALS ========================================== const int width = 500; const int height = 500; const int imgsize = 3; bool key[5] = {false, false, false, false, false}; bool running = true; bool draw = true; // FUNCTIONS ======================================== void initSpaceship(Spaceship &ship); void moveSpaceshipRight(Spaceship &ship); void moveSpaceshipLeft(Spaceship &ship); void initInvader(Invader &invader); void moveInvaderRight(Invader &invader); void moveInvaderLeft(Invader &invader); void initBullet(Bullet &bullet); void fireBullet(); void doCollision(); void updateInvaders(); void drawText(); enum key_t { UP, DOWN, LEFT, RIGHT, SPACE }; enum source_t { INVADER, DEFENDER }; int main(void) { if(!al_init()) { return -1; } Spaceship ship; Invader invader; Bullet bullet; al_init_image_addon(); al_install_keyboard(); al_init_font_addon(); al_init_ttf_addon(); ALLEGRO_DISPLAY *display = al_create_display(width, height); ALLEGRO_EVENT_QUEUE *event_queue = al_create_event_queue(); ALLEGRO_TIMER *timer = al_create_timer(1.0 / 60); ALLEGRO_BITMAP *images[imgsize]; ALLEGRO_FONT *font1 = al_load_font("arial.ttf", 20, 0); al_register_event_source(event_queue, al_get_keyboard_event_source()); al_register_event_source(event_queue, al_get_display_event_source(display)); al_register_event_source(event_queue, al_get_timer_event_source(timer)); images[0] = al_load_bitmap("defender.bmp"); images[1] = al_load_bitmap("invader.bmp"); images[2] = al_load_bitmap("explosion.bmp"); al_convert_mask_to_alpha(images[0], al_map_rgb(0, 0, 0)); al_convert_mask_to_alpha(images[1], al_map_rgb(0, 0, 0)); al_convert_mask_to_alpha(images[2], al_map_rgb(0, 0, 0)); initSpaceship(ship); initBullet(bullet); initInvader(invader); al_start_timer(timer); while(running) { ALLEGRO_EVENT ev; al_wait_for_event(event_queue, &ev); if(ev.type == ALLEGRO_EVENT_TIMER) { draw = true; if(key[RIGHT] == true) moveSpaceshipRight(ship); if(key[LEFT] == true) moveSpaceshipLeft(ship); } else if(ev.type == ALLEGRO_EVENT_DISPLAY_CLOSE) running = false; else if(ev.type == ALLEGRO_EVENT_KEY_DOWN) { switch(ev.keyboard.keycode) { case ALLEGRO_KEY_ESCAPE: running = false; break; case ALLEGRO_KEY_LEFT: key[LEFT] = true; break; case ALLEGRO_KEY_RIGHT: key[RIGHT] = true; break; case ALLEGRO_KEY_SPACE: key[SPACE] = true; break; } } else if(ev.type == ALLEGRO_KEY_UP) { switch(ev.keyboard.keycode) { case ALLEGRO_KEY_LEFT: key[LEFT] = false; break; case ALLEGRO_KEY_RIGHT: key[RIGHT] = false; break; case ALLEGRO_KEY_SPACE: key[SPACE] = false; break; } } if(draw && al_is_event_queue_empty(event_queue)) { draw = false; al_draw_bitmap(images[0], ship.pos_x, ship.pos_y, 0); al_flip_display(); al_clear_to_color(al_map_rgb(0, 0, 0)); } } al_destroy_font(font1); al_destroy_event_queue(event_queue); al_destroy_timer(timer); for(int i = 0; i < imgsize; i++) al_destroy_bitmap(images[i]); al_destroy_display(display); } // FUNCTION LOGIC ====================================== void initSpaceship(Spaceship &ship) { ship.lives = 3; ship.speed = 2; ship.pos_x = width / 2; ship.pos_y = height - 20; } void initInvader(Invader &invader) { invader.health = 100; invader.count = 40; invader.speed = 0.5; invader.pos_x = 300; invader.pos_y = 300; } void initBullet(Bullet &bullet) { bullet.speed = 10; } void moveSpaceshipRight(Spaceship &ship) { ship.pos_x += ship.speed; if(ship.pos_x >= width) ship.pos_x = width-30; } void moveSpaceshipLeft(Spaceship &ship) { ship.pos_x -= ship.speed; if(ship.pos_x <= 0) ship.pos_x = 0+30; } However it's not behaving the way I want it to behave, in fact the behavior for the ship movement is un-normal. Basically I specified that the ship only moves when the right/left key is down, however the ship is moving constantly to the direction of the key pressed, it never stops although it should only move while my key is down. Even more weird behavior, when I press the opposite key the ship completely stops no matter what else I press. What's wrong with the code? Why does the ship move constantly even after I specified it only moves when a key is down?

How to change icons of specific file types on Ubuntu 11.10?

- by Curious Apprentice

I want to change file icons of some specific file types like- .html, .css etc. I have tried using "File Type Editor (assogiate)" which is not working. I have also tried using "Gnome Tweak Tool" using icon themes. But that also does not worked properly (Though I can change folder icons , dash menu icons but not file icons). Please suggest me a way so that I can change file icons properly. I have read some of the articles saying about some mime type changes. I could not get proper guide from any of those articles. If there is such a way then please write in detail. Many Many Thanks in Advance :)

Mounting ddrescue image after recovery (in over my head)

- by BorgDomination

I'm having problems mounting the recovery image. I've tried to mount the image multiple ways. quark@DS9 ~ $ sudo mount -t ext4 /media/jump1/1recover/sdb1.img /mnt mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so quark@DS9 ~ $ sudo mount -r -o loop /media/jump1/1recover/sdb1.img recover mount: you must specify the filesystem type quark@DS9 ~ $ sudo mount /media/jump1/1recover/sdb1.img mnt mount: you must specify the filesystem type It doesn't even give me detailed information on the file I just made, nautilus says it's 160gb. quark@DS9 ~ $ file /media/jump1/1recover/sdb1.img /media/jump1/1recover/sdb1.img: data quark@DS9 ~ $ mmls /media/jump1/1recover/sdb1.img Cannot determine partition type I'm not sure what I'm doing wrong or if I started this process incorrectly from the beginning. I've outlined what I've done so far below. I'm clueless, I'd appreciate if someone had some input for me. What I have done from the beginning My laptop has two hard drives. One has the dual boot Win7 / Linux Mint system files. Secondary one contained my /home folder. The laptop was jarred and the /home disk was broken. I tried a LiveCD recovery, it failed. Wouldn't even load a Live session with the disk installed. So I turned to ddrescue. quark@DS9 ~ $ sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009fc18 Device Boot Start End Blocks Id System /dev/sda1 * 2048 112642047 56320000 7 HPFS/NTFS/exFAT /dev/sda2 138033152 312580095 87273472 83 Linux /dev/sda3 112644094 138033151 12694529 5 Extended /dev/sda5 112644096 132173823 9764864 83 Linux /dev/sda6 132175872 138033151 2928640 82 Linux swap / Solaris Partition table entries are not in disk order Disk /dev/sdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0002a8ea Device Boot Start End Blocks Id System /dev/sdb1 * 63 312576704 156288321 83 Linux Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xed6d054b Device Boot Start End Blocks Id System /dev/sdc1 63 1953520064 976760001 7 HPFS/NTFS/exFAT sda - 160g internal, holds all system files and all computer functions. sdb - 160g internal, BROKEN, contains about 140g of data I'd like to recover. sdc - 1T external, contains recovery image. Only place that has space to do all this. From this site, https://apps.education.ucsb.edu/wiki/Ddrescue I used this script to create an image of the broken hard drive.

Does this mean all of my data is lost???????? Appreciate ANY input!
