• [mac] Running an Automator task at night

  - by Roberto Aloi

  I've just created an Automator workflow and I'm using crontab to execute it at night. The problem is that, after a while, the machine is going to sleep and a password is required (this is the intended behaviour). Unfortunately, Automator seems to be unable to perform the task when the password is required. It works like a charm if the "password required" dialog is not displayed (before the sleep). Any suggestion on how to solve this?

• I can't find a DirectX installer to run from my installer.

  - by John

  I tried this one. But it's the annoying one which asks you where to extract temp files, my users won't know what this means. I also tried the web installer, but you're not strictly allowed to use this. I don't really follow the windows setup stuff, but is there a single .EXE I am allowed to distribute and run, which just works (for DX 9.0C) with some command-line args? Or some other way, which can can described in idiot-proof steps and and called in one command-line argument from an installer script like Inno?

• How to call C++ function from C?

  - by claws

  I know this. Calling C function from C++: If my application was in C++ and I had to call functions from a library written in C. Then I would have used //main.cpp extern "C" void C_library_function(int x, int y);//prototype C_library_function(2,4);// directly using it. This wouldn't mangle the name C_library_function and linker would find the same name in its input *.lib files and problem is solved. Calling C++ function from C??? But here I'm extending a large application which is written in C and I need to use a library which is written in C++. Name mangling of C++ is causing trouble here. Linker is complaining about the unresolved symbols. Well I cannot use C++ compiler over my C project because thats breaking lot of other stuff. What is the way out? By the way I'm using MSVC

• What do browsesr use to auto suggest values in web forms?

  - by nedlud

  If I come back to a web site after having filled in a form previously, the browser remembers my username (for example). I'm not talking about cookies remembering user names and passwords, but the way a browser will suggest a value for a previously submitted field. What controls this behaviour? My issue at the moment is that I have login forms on several small apps all running under the one domain. (eg www.example.com/app1/login/ and www.example.com/app2/login/). If I use my user name for app1, then go over to app2 where I use a different username, it only ever auto suggests my app1 user name. How can I change this behaviour? Do browsers use the fields ID to help remember this stuff? If I change the ID of the fields in the login form, will they auto suggest the correct values in future?

• HRESULT exception not caught in VS 2008

  - by arionik

  Hello all, I've got a stange situation in visual studio 2008 C++. I work on code that was originally written for visual studio 2003, where everything works well. Now, ported to VS 2008, the exception handling, which unfortuantely exists widely in the code, does not work anymore. standard code example: try { HRESULT hr = S_OK; // do stuff... if( FAILED( hr ) ) throw hr; } catch( HRESULT hr ) { // error handling, but we never get here } catch( ... ) { // ... not even here } Under VS 2008, no exception is encountered, but I get a crash somewhere else, indicating that the stack pointer must be screwed up. Did anybody come across this behaviour? Any help is appreciated.

• Augeas - create new ini section

  - by Tim Brigham

  I have a config file in augeas using a custom lens that outputs the data as follows. /files/opt/../server.conf/target[1] = "general" /files/opt/../server.conf/target[1]/serverName = "XXX" /files/opt/../server.conf/target[1]/guid = "XXX0XXX" /files/opt/../server.conf/target[2] = "sslConfig" /files/opt/../server.conf/target[2]/sslKeysfilePassword = "$1$XXXXX" This works well - some of the target names contain colons, etc so I need to use the target[x] format. What is the correct ins syntax to create a new section in my INI using this syntax?

• Android/Java Javadoc missing after updating Android SDK

  - by binnyb

  After i recently installed the new Android SDK stuff, I no longer can view the Javadoc while editing my project's code. I get this message: Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc. I am getting this message for all methods, variables, classes, etc. I have installed the documentation and everything available to me via the android update manager. I have also tried to do a clean install of the android sdk and eclipse, and no luck getting the javadoc working. I have also tried manually setting the javadoc via project properties -> javadoc location -> file:/C:/Program Files/Android/android-sdk-windows/docs/reference/ with no luck What suggestions do you have that could fix this problem?

• Deleting a cookie in Javascript not working

  - by DisgruntledGoat

  I have a site where authentication is done externally (which I can't access), so I'm creating a cookie on login in order to display a welcome message to the user. Creating the cookie works fine, I write to document.cookie when the login form submits. But deleting the cookie doesn't work. Here's my code (logout.php does the external authentication stuff): <a href="http://external.com/logout.php" style="float:right" onclick="document.cookie='BRLOG=; expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/; domain=.example.com;'">Logout</a>

• Site down, SSH and FTP work fine

  - by Euskadi

  I cannot access my site through my web browser, using either the domain name or IP address (which also pings fine). My site was working last night when I went to bed, so I can't think what might have done it. I have tried restarting apache to no avail. update: I've noticed that http://[IP Address]/phpymyadmin works but [domain name]/phpmyadmin does not, and the same happens for webmin (https://[IP]:1000). Could this be a problem with BIND?

• Print from MAC OS 10.5.8 to HPC3180 on Windows 7, How?

  - by Tom Groszko

  Can anyone point to a document that describes how to print from a Max OS 10.5.8 to an HP Photosmart C3180 series print connected to Windows 7. I can’t get anything but nonsense to print. I was able to do this with Windows XP, could not do it with Vista and am now hopping to get it done with System 7. HP has been no help at all. Apparently nobody who works for them knows anything about both computers.

• Iphone UI Size / Layout Resource?

  - by blindJesse

  Is anyone aware of a website or download to reference for the size of UI elements or standard iphone interface stuff? What I mean is something that gives the height of elements like the status bar, tab bar, navigation bar, default tableviewcell height (and such things as width of accessory view, indentation, etc), default icon sizes, default font sizes for UI elements (if they need to be mimicked, for instance), etc etc etc. It's amazing how many times I have to go back to find a reference or estimate the size and position of a standard element. It seems like it would be an invaluable resource that could fit on a printed page or two.

• Get Flickr Sets

  - by PaulAdamDavis

  Hi everyone. Usual stuff, Googled forever, looked on here, no help. Yet. What I want is to list the sets of photos I have on Flickr. Nice & simple, it would seem. I want the 'title image' (the one used as the thumb for it on Flickr its self), the title and URL. Can't be that hard, can it? The language of choice is PHP (5.1.6), or JS (jQuery if possible). Both are good.

• Can't do SSH public key under cryptographed home [migrated]

  - by lucasvscn

  Sorry if I post this in the wrong place. I've readed this topic, but I not able to comment on someones answer, so I started a new topic. I can't do ssh public key login to my server and I think this issue is related to the fact my home is using cryptography which set the permissions to 700 on /home/MY-USER I've tried another workstation and everything works fine. I would be glad if someone help me to get out this without revert the cryptography.

• Why would a 'public event EventHandler cccc' be null?

  - by Matt

  Why would a 'public event EventHandler cccc' be null? I have a class that's public class Builder { public event EventHandler StartedWorking; public Builder() { // Constructor does some stuff } public void Start() { StartedWorking(this, eventargobject); //StartedWorking is null -- } } This seems straightforward and something I do all the time? Am I missing something obvious or is there something that could cause this? EDIT: Does this mean that if I fire an event that is not subscribed to in a client class I have to check that it is not null? EDIT-2: I guess I'd never had events that were never not subscribed to and hence never ran into this -- You learn something new every day Sorry about the seemingly stupid question....

• setting up linked list Java

  - by erp

  I'm working on some basic linked list stuff, like insert, delete, go to the front or end of the list, and basically i understand the concept of all of that stuff once i have the list i guess but im having trouble setting up the list. I was wondering of you guys could tell me if im going in the right direction. (mostly just the setup) this is what i have so far: public class List { private int size; private List linkedList; List head; List cur; List next; /** * Creates an empty list. * @pre * @post */ public List(){ linkedList = new List(); this.head = null; cur = head; } /** * Delete the current element from this list. The element after the deleted element becomes the new current. * If that's not possible, then the element before the deleted element becomes the new current. * If that is also not possible, then you need to recognize what state the list is in and define current accordingly. * Nothing should be done if a delete is not possible. * @pre * @post */ public void delete(){ // delete size--; } /** * Get the value of the current element. If this is not possible, throw an IllegalArgumentException. * @pre the list is not empty * @post * @return value of the current element. */ public char get(){ return getItem(cur); } /** * Go to the last element of the list. If this is not possible, don't change the cursor. * @pre * @post */ public void goLast(){ while (cur.next != null){ cur = cur.next; } } /** * Advance the cursor to the next element. If this is not possible, don't change the cursor. * @pre * @post */ public void goNext(){ if(cur.next != null){ cur = cur.next;} //else do nothing } /** * Retreat the cursor to the previous element. If this is not possible, don't change the cursor. * @pre * @post */ public void goPrev(){ } /** * Go to top of the list. This is the position before the first element. * @pre * @post */ public void goTop(){ } /** * Go to first element of the list. If this is not possible, don't change the cursor. * @pre * @post */ public void goFirst(){ } /** * Insert the given parameter after the current element. The newly inserted element becomes the current element. * @pre * @post * @param newVal : value to insert after the current element. */ public void insert(char newVal){ cur.setItem(newVal); size++; } /** * Determines if this list is empty. Empty means this list has no elements. * @pre * @post * @return true if the list is empty. */ public boolean isEmpty(){ return head == null; } /** * Determines the size of the list. The size of the list is the number of elements in the list. * @pre * @post * @return size which is the number of elements in the list. */ public int size(){ return size; } public class Node { private char item; private Node next; public Node() { } public Node(char item) { this.item = item; } public Node(char item, Node next) { this.item = item; this.next = next; } public char getItem() { return this.item; } public void setItem(char item) { this.item = item; } public Node getNext() { return this.next; } public void setNext(Node next) { this.next = next; } } } I got the node class alright (well i think it works alright), but is it necessary to even have that class? or can i go about it without even using it (just curious). And for example on the method get() in the list class can i not call that getItem() method from the node class because it's getting an error even though i thought that was the whole point for the node class. bottom line i just wanna make sure im setting up the list right. Thanks for any help guys, im new to linked list's so bear with me!

• Speed of running a test suite in Rails

  - by Milan Novota

  I have 357 tests (534 assertions) for my app (using Shoulda). The whole test suite runs in around 80 seconds. Is this time OK? I'm just curious, since this is one of my first apps where I write tests extensively. No fancy stuff in my app. Btw.: I tried to use in memory sqlite3 database, but the results were surprisingly worse (around 83 seconds). Any clues here? I'm using Macbook with 2GB of RAM and 2GHz Intel Core Duo processor as my development machine.

• PHP find if file data is an image

  - by Christian Sciberras

  Imagine I have some file data in a variable $data. I need to determine whether it is an image or not. No need for details such as corrupt images etc. Firs thought would be getting the file mime type by looking at the magic number and then see whether "image" is in the mime type. No such luck, even if I have a "file extension to mime type" script, I don't have a reliable way to get mime from magic number. My next option was to have a reasonable list of image file magic numbers and consult them. However, it relatively difficult to find such magic numbers (gif for instance has different magic numbers, some of which could pretty rare - if memory serves me right). A better idea would be some linux program which can do this kind of thing. Any ideas? I'm running RHEL and PHP 5.3. I've got root access - ie able to install stuff if needed. - Chris.

• C++: How to make comparison function for char arrays?

  - by Newbie

  Is this possible? i get weird error message when i put char as the type: inline bool operator==(const char *str1, const char *str2){ // ... } Error message: error C2803: 'operator ==' must have at least one formal parameter of class type ... which i dont understand at all. I was thinking if i could directly compare stuff like: const char *str1 = "something"; const char *str2 = "something else"; const char str3[] = "lol"; // not sure if this is same as above and then compare: if(str1 == str2){ // ... } etc. But i also want it to work with: char *str = new char[100]; and: char *str = (char *)malloc(100); I am assuming every char array i use this way would end in NULL character, so the checking should be possible, but i understand it can be unsafe etc. I just want to know if this is possible to do, and how.

• VM Virtual guest machine disk defrag improves performance, myth or reality?

  - by jafin

  In operation of a virtual Vmware or Hyper-V guest typically advice is given to defrag the host and virtual disk images so to result in improved performance. Something like a cmd: vmware-vdiskmanager -d <file.vmdk> works great. Yet I can't find any qualitive evidence that suggest defraging inside the guest VM improves performance. Does anyone have advice or evidence that doesn't come from a commercial defragger's whitepaper that suggests inside guest defragging helps?

• How could a share a Google map mashup with my own datapoints and links back to my site?

  - by rball

  I currently have a map mashup that has locations that I'm populating from my own database. A few users would like to also show that map on their site(s). I'd like to give them the ability to do that, but would like to retain the actual functionality of the map on my own site: like add "stuff" to places on the map through my a web form on my site. I could open the entire API to allow them to create their own form along with the data points, but most of the people wanting to put up the map aren't developers, they are just enthusiasts that have put together a personal page that they want to spice up. I was thinking I could just provide a JavaScript of some kind that they could then take to place on their site, or maybe an IFRAME of some type, or...any ideas? Anyone implemented this? TIA.

• Something wrong with redirects on my Joomla 1.5.18 site

  - by fuzzy lollipop

  My Joomla 1.5.18 site, I enabled login, when I click login the page I get sent to is NOT styled with CSS. If I login it redirects to the home page and it is not styled anymore either. It looks like it is recursively appending stuff to the URL incorrectly. http://www.myjoomlasite.org/index.php/index.php/login if I click on home page or login links it keeps putting more and more index.php entries in the URL, and sometimes on the end. The following is what I get when I try and go to a JEvents menu item. http://www.myjoomlasite.org/index.php/index.php/index.php/index.php/upcomingevents/month.calendar/2010/06/09/index.php Anyone have any idea why this is happening? I don't know what to search for on Google apparently, and none of the Joomla! books I have address this.

• Binary diff/patch for large files on linux?

  - by thejh

  I've got two partition images (A and B) and want to use them to create a patch that I can apply on A on another computer in order to get the new B image without flooding the network. I have the following requirements: works on linux can create diffs can use diffs to patch files can handle binary files can handle large files (a few hundred GB should work) no user interaction required (just a console application) ideally, should be able to read from/write to pipes (so that I can pipe into it from a gzip-compressed file and write to one) Does something like that exist?

• Has anyone properly interpreted HTTP request based on this demo of winpcap?

  - by httpinterpret

  The example is here, and I tried it by changing the filter to tcp and dst port 80 and the following: void packet_handler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) { .... ip_len = (ih->ver_ihl & 0xf) * 4; tcp_len = (((u_char*)ih)[ip_len + 12] >> 4) * 4; tcpPayload = (u_char*)ih + ip_len + tcp_len; /* start of url - skip "GET " */ url = tcpPayload + 4; end_url = strchr((char*)url, ' '); url_length = end_url - url; final_url = (u_char*)malloc(url_length + 1); strncpy((char*)final_url, (char*)url, url_length); final_url[url_length] = '\0'; printf("%s\n", final_url); .... } But through debug, I see tcpPayload is full of messy code,not supposed "GET ..." stuff. What's wrong with my implement?

• Does the Internet make us less good programmers? [closed]

  - by stagas

  With all the information and code available nowadays on the Internet has that diminished our capability of remembering or learning stuff just because we know they're available somewhere out there, just a Google away or a StackOverflow question away? For example I find myself visiting php.net quite often to check the syntax of the same functions over and over again, not because my memory sucks, but I don't feel like keeping the information in me, since I know I'll find it again on the net. And about StackOverflow, isn't the process of figuring things out on your own supposed to improve your programming skills? If the answers are all just clicks away, do we actually learn something or just keep a pointer in our heads where to search for it again when we need it? Your thoughts are welcome. Hope it doesn't shut down as subjective or anything, the answers would be really interesting ;)
