• How do I stop ssh-agent from forgetting my password after I login to the screen session from SSH?

  - by Shwouchk

  I have a screen session open in an lxterminal window. If I SSH somewhere, the first time it happens, an ssh-agent window opens and asks me for my private key passphrase, and after that ssh goes right on. If I log in from outside to this machine and attach to the screen session however, ssh-agent now asks me every time I connect for my passphrase, in the terminal. Is there a way to avoid this and to let it continue using the X agent, or at least to have the non-X agent remember the passphrase?

• Is it possible to mod_rewrite BASED on the existence of a file/directory and uniqueID? [closed]

  - by JM4

  My site currently forces all non www. pages to use www. Ultimately, I am able to handle all unique subdomains and parse correctly but I am trying to achieve the following: (ideally with mod_rewrite): when a consumer visits www.site.com/john4, the server processes that request as: www.site.com?Agent=john4 Our requirements are: The URL should continue to show www.site.com/john4 even though it was redirected to www.site.com?index.php?Agent=john4 If a file (of any extension OR a directory) exists with the name, the entire process stops an it tries to pull that file instead: for example: www.site.com/file would pull up (www.site.com/file.php if file.php existed on the server. www.site.com/pages would go to www.site.com/pages/index.php if the pages directory exists). Thank you ahead of time. I am completely at a crapshot right now.

• Laptop crashes when connecting to external harddisk

  - by Gnot

  I recently had a problem with my laptop. when I booted up the machine, I would get a SMART failure error message and when I pressed F1 to continue, it would take a very long time to boot and it would come back to the same error message again. Thinking that my hard disk was dying, I bought a new hard disk and installed on my laptop and so now my laptop is alright. However I need to recover data from that old hard disk, so I bought an external hard disk case and placed the old hard disk onto the case and connected to my laptop with USB. The first few times when I connected, I could see the files from the old hard disk and managed to copy some files over although it took extremely long to transfer. But now whenever I connect to the old hard disk, after a few minutes, my laptop will crash and re-boot. Do you think my old hard disk is dead beyond repair? Or you can offer some help here? Any assistance would be appreciated!

• Rails 3, Devise and custom controller action

  - by Johnny Klassy

  routes.rb match 'agencies/stub' => 'agencies#stub', :via => :get resources :agencies Here's the rake routes dump agencies_stub GET /agencies/stub(.:format) {:controller=>"agencies", :action=>"stub"} agencies GET /agencies(.:format) {:action=>"index", :controller=>"agencies"} POST /agencies(.:format) {:action=>"create", :controller=>"agencies"} new_agency GET /agencies/new(.:format) {:action=>"new", :controller=>"agencies"} edit_agency GET /agencies/:id/edit(.:format) {:action=>"edit", :controller=>"agencies"} agency GET /agencies/:id(.:format) {:action=>"show", :controller=>"agencies"} PUT /agencies/:id(.:format) {:action=>"update", :controller=>"agencies"} DELETE /agencies/:id(.:format) {:action=>"destroy", :controller=>"agencies"} Devise is setup to have all agenciesroutes only accessible as admin. The call I'm testing with is http://xyz:12345@localhost:3000/agencies/stub but it doesn't authenticate properly, ie, it doesn't recognize it as admin and throws me back to the Devise login page. The creds are a valid admin account. I'm baffled and have no idea why this is happening. Any insights will be much appreciated.

• Defined outlets, connected them, they all returns (null)

  - by Tom

  Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView: EDIT: That is how I call the view: DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; dvController.workflow_id = parent_id; Etape *etape = [[Etape alloc] init]; dvController.etapes = [etape getEtapes:parent_id]; [etape release]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release];

• Cakephp cache only caching one file per action

  - by Jamesz

  Hi, I have a songs controller. Within the songs controller i have a 'view' action which get's passed an id, eg /songs/view/1 /songs/view/5 /songs/view/500 When a user visits /songs/view/1, the file is cached correctly and saved as 'songs_view_1.php' Now for the problem, when a user hit's a different song, eg /songs/view/2, the 'songs_view_1.php' is deleted and '/songs/view/2.php' is in it's place. The cahced files will stay there for a day if I don't visit a different url, and visiting a different action will not affect any other action's cached file. I've tried replacing my 'cake' folder (from 1.2 to 1.2.6), but that didn't do anything. I get no error messages at all and nothing in the logs. Here's my code, I've tried umpteen variations all ending up with the same problem. var $helpers = array('Cache'); var $cacheAction = array( 'view/' => '+1 day' ); Any ideas? EDIT: After some more testing, this code var $cacheAction = array( 'view/1' => "1 day", 'view/2' => "1 day" ); will cache 'view/1' or 'view/2', but delete the previous page as before. If I visit '/view/3' it will delete the cached page from before... sigh EDIT: Having the same issue on another server with same code...

• Export Import error 'SSIS Data Flow Task could not be created' ... registering DTSPipeline.dll, cannot create task "STOCK:PipelineTask"

  I'm about to throw in the towel on this one. Running SQL Server 2008 enterprise on Windows 7 x64. Can't get past this issue.

• Stop Windows 7 from installing critical updates

  - by Rico

  I have disabled Windows Update on Windows 7, but it still downloads and installs critical updates. As with Windows XP, these updates occasionally create problems. But in XP, once I disabled automatic updates, the OS did not override my settings and continue to download and install critical updates. After the most recent critical update to Windows 7, every time I boot up, the USB devices connected to a single port through 4-way hub don't install. I have to unplug the hub from the computer then plug it back in. Then the devices install. I can use System Recovery to solve the immediate problem, but I'd like to disable automatic updates entirely. Why does Windows 7 not respect my settings like Windows XP did?

• Forcing exact hostname match in IIS

  - by iis_newbie

  I am looking how to force an exact hostname match within IIS when using https. For instance, I want "https://works.mysite.com/resource" to be ok, but "https://noworks.mysite.com/resource" to return 404 (assuming they both resolve to the same IP). IIUC, the default behavior of IIS when going to "https://noworks.mysite.com/resource" is to get a cert warning, if the user presses continue, the user is able to access the URL. I was able to do this by generating a *.mysite.com SSL cert, and then specify the hostname within the bindings in IIS, but without the * in the beginning, the hostname field is disabled and blank. Am I missing something simple here?

• Apache Issues on Windows Server 2008

  - by dlackey

  I'm looking to reinstall Apache 2.2.25 since I continue to get these errors in the Windows Application log every 2-5 minutes: Faulting application name: httpd.exe, version: 2.2.25.0, time stamp: 0x51dd049c Faulting module name: zlib1.dll, version: 1.2.3.0, time stamp: 0x4790446a Exception code: 0xc0000005 Fault offset: 0x00002bad Faulting process id: 0x38e8 Faulting application start time: 0x01cfbfd70cdfbc4f Faulting application path: C:\Apache2\bin\httpd.exe Faulting module path: C:\Apache2\bin\zlib1.dll Report Id: 745f20de-2bca-11e4-bd5d-002590f28d7e If the new install doesn't work or if there are some "issues", can I simply restore the Apache2 directory from backup and then I'll just be back where I started? I thought about just renaming the current install to something like c:\apache2_old and if something fails, I can delete the new install and rename c:\apace2_old back to c:\apache. What do you all think?

• Why isn't Adobe software multilingual?

  - by Takowaki

  I work in a design studio with several non-native English speakers (in this case, into Japanese and Chinese). I have installed the latest Creative Suite (CS5) on our mac stations and was once again disappointed that unlike so many modern software packages there is still no option to change the language of the software. Most of the team has been good enough to work on their English, but it would be much more helpful for them to work in their native language. Why does Adobe continue to require separate licenses based on language? Are they operating under the assumption that only a single language is ever spoken in any given country? Are there any other third party options or does Adobe at least have some sort of statement regarding this policy?

• block access to certain website types

  - by frustrated teacher

  Need to block access to certain website types without listing each URL to block. Students at secondary school are going to porn sites. Need to be able to block all such access without having to list each possible site URL. Having the Content -- Ratings tab set to None for all categories on the ratings files listed on my computers does not prevent access. Unchecking users may access sites with no rating, even with the security settings set to High, still allows the porn sites to come up. If that is checked, then ONLY listed sites can open and students would not be able to do any research via google, for example. I would rather not have to continue checking each computer and blocking sites as they find them.

• Merge Sort issue when removing the array copy step

  - by Ime Prezime

  I've been having an issue that I couldn't debug for quite some time. I am trying to implement a MergeSort algorithm with no additional steps of array copying by following Robert Sedgewick's algorithm in "Algorithm's in C++" book. Short description of the algorithm: The recursive program is set up to sort b, leaving results in a. Thus, the recursive calls are written to leave their result in b, and we use the basic merge program to merge those files from b into a. In this way, all the data movement is done during the course of the merges. The problem is that I cannot find any logical errors but the sorting isn't done properly. Data gets overwritten somewhere and I cannot determine what logical error causes this. The data is sorted when the program is finished but it is not the same data any more. For example, Input array: { A, Z, W, B, G, C } produces the array: { A, G, W, W, Z, Z }. I can obviously see that it must be a logical error somewhere, but I have been trying to debug this for a pretty long time and I think a fresh set of eyes could maybe see what I'm missing cause I really can't find anything wrong. My code: static const int M = 5; void insertion(char** a, int l, int r) { int i,j; char * temp; for (i = 1; i < r + 1; i++) { temp = a[i]; j = i; while (j > 0 && strcmp(a[j-1], temp) > 0) { a[j] = a[j-1]; j = j - 1; } a[j] = temp; } } //merging a and b into c void merge(char ** c,char ** a, int N, char ** b, int M) { for (int i = 0, j = 0, k = 0; k < N+M; k++) { if (i == N) { c[k] = b[j++]; continue; } if (j == M) { c[k] = a[i++]; continue; } c[k] = strcmp(a[i], b[j]) < 0 ? a[i++] : b[j++]; } } void mergesortAux(char ** a, char ** b, int l, int r) { if(r - l <= M) { insertion(a, l, r); return; } int m = (l + r)/2; mergesortAux(b, a, l, m); //merge sort left mergesortAux(b, a, m+1, r); //merge sort right merge(a+l, b+l, m-l+1, b+m+1, r-m); //merge } void mergesort(char ** a,int l, int r, int size) { static char ** aux = (char**)malloc(size * sizeof(char*)); for(int i = l; i < size; i++) aux[i] = a[i]; mergesortAux(a, aux, l, r); free(aux); }

• What do I do with this error I get when uninstalling Microsoft Office 2007?

  - by Solitario

  I am on a study to create an add-in in outlook using Visual Studio 2010. But as I had Microsoft Office 2007 it was showing an error while debugging. So, I thought of installing Microsoft Office 2010, after installation of Microsoft office 2010 only I noticed that I haven't uninstalled the Office 2007. While attempting to uninstall Microsoft Office 2007 it shows a dialog box saying, The Language of this installation package is not supported by your system. What might be the problem and how could I uninstall Office 2007? Is there any possibility that I could go on continue my work without uninstalling Office 2007?

• Span with white-space style in IE (7) applied _past_ end of span

  - by WaldenL

  We've got an application where users can enter "notes" into a rich edit control (Telerik's RedEditor, but that doesn't matter here). We had a user enter notes from w/in Safari that had a <span></span> in the middle of the note, and that span had a style on it specifying white-space:pre The HTML of the note was in the form of: <div> This is a note <span class="Apple-tab-span" style="white-space: pre; "> </span> and here's more of the note. </div> Simple enough, the style should apply to the span, and the span had 4 spaces in it. There should have been 4 spaces in the resulting output. Here's the problem. IE seems to apply that white-space: pre; style not only to the span, but to the enclosing div! Therefore, this long line that should have wrapped since it's not in the span, now pushed the document out until the line fits on the page. What am I missing. I know IE has problems, but this doesn't seem right, even for IE. So, the question(s): 1) Am I correct that the white-space attribute should only have applied to the span? 2) Can this be resolved somehow? Remember, I'm not in control of the content being entered. And it's entered from a mac w/Safari and being viewed in IE. Edit: The doctype on the page in question is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

• Transfer hard-drive with windows XP to another computer. On booting, asks to activate xp

  - by Jesse

  I had an old computer sitting around that I have not been able to boot successfully. I moved the hard drive and placed it in my newer computer. If I boot linux, I can mount the XP hard-drive and access the files. If I try to boot from the XP hard-drive, it will boot, but it asks me to activate windows before proceeding. If I continue, I get the "activation window" with two images/icons(?) which are failing to load. Nothing else happens. The version of windows came with the original computer the hard-drive came from, so I'm not sure if I'm married to the broken computer (I hope not!). Is there anything I can do in order to boot into XP from the new computer?

• Is the decision to use SNI or IP based SSL made during cert purchase or cert installation?

  - by Neil Thompson

  It's time to renew an SSL cert - but the website will soon be moving from a dedicated machine with a fixed IP to a cloud based host behind a load balancer. When I renew or re-purchase my ssl cert do I make the decision about whether it should be an SNI / IP based SSL Cert at the point of purchase - or is a cert a cert and it's all about where and how it's installed? I'm hoping the renewed cert can continue to be IP based for now, and in a few months when the website (and it's domain ofc) moves to the cloud I can re-use the cert in 'SNI mode'

• TreeView update bug in the VB.NET

  - by CFP

  Consider the following code: Dim Working As Boolean = False Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterCheck If Working Then Exit Sub Working = True e.Node.Checked = Not e.Node.Checked Working = False End Sub Private Sub TreeView1_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseClick If e.Button = Windows.Forms.MouseButtons.Right Then MsgBox("Checked = " & TreeView1.SelectedNode.Checked) End Sub Where TreeView1 is a TreeView added to the form, with CheckBoxes set to true and one node added. The code basically cancel any node checking occuring on the form. Single-clicking the top node to check it works well : your click is immediately canceled. Yet if you double-click the checkbox, it will display a tick. But verifying the check state through a right click will yield a Checked = False dialog. How come? Is it a bug (I'm using the latest .Net Framework 4.0, and he same occurs in 2.0), or am I doing something wrong here? Is there a work around? Thanks! EDIT: Additionally, the MouseDoubleClick event is not raised before you click once again. EDIT 2: Posted a bug report at Microsoft Connect

• Startup script for Windows Recovery Environment?

  - by Recovery

  I'm trying to automate the Windows 7 Recovery Environment. I want the computer to be able to boot into the Recovery Environment, automatically run some commands, and then restart back into Windows. The reason for this is that I want to use the Recovery Environment to edit some system files that are not writable while Windows is running. (Of course, this could be done using GRUB and Linux, but it would be even better if one could use the built-in Windows Recovery Environment and avoid the need to install a separate bootloader and OS.) So far, I've found out how to tell Windows 7 to reboot into the recovery environment: reagentc /boottore shutdown /r /t 0 But once the Recovery Environment loads, it opens a dialog that requires user input to continue. Instead of that dialog, I would like to be able to specify a script to run instead. Any ideas on how to accomplish this would be appreciated. Thanks!

• c++ specialized overload?

  - by acidzombie24

  -edit- i am trying to close the question. i solved the problem with boost::is_base_and_derived In my class i want to do two things. 1) Copy int, floats and other normal values 2) Copy structs that supply a special copy function (template T copyAs(); } the struct MUST NOT return int's unless i explicitly say ints. I do not want the programmer mistaking the mistake by doing int a = thatClass; -edit- someone mention classes dont return anything, i mean using the operator Type() overload. How do i create my copy operator in such a way i can copy both 1) ints, floats etc and the the struct restricted in the way i mention in 2). i tried doing template <class T2> T operator = (const T2& v); which would cover my ints, floats etc. But how would it differentiate from structs? so i wrote T operator = (const SomeGenericBase& v); The idea was the GenericBase would be unsed instead then i can do v.Whatever. But that backfires bc the functions i want wouldnt exist, unless i use virtual, but virtual templates dont exist. Also i would hate to use virtual I think the solution is to get rid of ints and have it convert to something that can do .as(). So i wrote something up but now i have the same problem, how does that differentiate ints and structs that have the .as() function template?

• How to nmot show any prompts when inserting a USB drive in Windows?

  - by jasondavis

  1) I just found a really interesting program that allows me to use a USB drive as a windows login key. It is called Rohos Logon Key. IF I remobve my USB drive/key from the PC then I can have the PC lock or hibernate or any other option, I have been looking for such a solution for many years but never knew one existed until this and it works much better then I imagined. I do have a couple minor issues though (im using Windows 7 pro). When I remove and then re-insert my USB key, windows prompts me with this dialog here... Generally when I get this I just click on "Continue without scanning" however I am looking for a solution to just make it not even show this at all, is it possible to disable it from showing? 2) I also get this dialog as well when I insert USB drives/key... Would it be possible to not show this as well or have it pick an option by default or anything really?

• Why is passing a string literal into a char* argument only sometimes a compiler error?

  - by Brian Postow

  I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0. EDIT: added code: char * host = FindArgDefault("EMailLinkHost", ""); stripCRLF(linkHost, '\n'); where: char *FindArgDefault(char *argName, char *defVal) {// simplified char * val = defVal; return(val); } and void stripCRLF(char *str, char delim) { char *p, *q; for (p = q = str; *p; ++p) { if (*p == 0xd || *p == 0xa) { if (p[1] == (*p ^ 7)) ++p; if (delim == -1) *p = delim; } *q++ = *p; } *q = 0; // DIES HERE } This compiled and ran until it tried to set *q to 0...

• Cross Platform C library for GUI Apps?

  Free of charge, simple to learn/use, Cross Platform C library for GUI Apps? Am I looking for Qt? Bonus question: Can I develop with the said library/toolkit on Mac then recompile on PC/Linux? Super Bonus Question: Link to tutorial and/or download of said library. (RE)EDIT: The truth is that I'm in the process of catching up on the C family (coming from web development - XHTML/PHP/MySQL) to learn iPhone development. I do understand that C is not C++ or ObjectiveC but I want to keep the learning curve as simple as possible. Not to get too off topic, but I am also on the lookout for good starter books and websites. I've found this so far. I'm trying to kill many birds with one stone here. I don understand that there are platform specific extensions, but I will try to avoid those for porting purposes The idea is that I want to write the code on one machine and just compile thrice.
