  • Unauthorized computer use via keyboard or remote access?

    - by brydaverambo
    I’m suspecting my computer is being used when I’m not at home. This is happening either physically or remotely. My wireless switch is off. Is there any way possible to detect and/or monitor activity without purchasing software? My settings are being changed as well as passwords (Bios PW was changed and I cannot access Bios settings). I connect via the network cable. Is it possible for someone (in range) to connect to my laptop even if the wireless switch is off? This is a Dell Inspiron 1720 with the WLAN 1395 card. Here’s the kicker. When I try to download freeware for monitoring activity, I am not allowed to do this! ????

  • Underlying Concept Behind Keyboard Mappings

    - by ajay
    I am frustrated with key mapping issues. On my Linux box, if I type Home/End in Vim, then the cursor actually moves to the beginning/end of the line. On my Mac when I am on TextEdit, if I do Fn + Left or Fn + Right, it takes me to beginning/end of the line. But if I am on Vim on my Mac terminal, then the same key combinations don't work. Why? I see online all the different cryptic settings that I have to paste in .vimrc to make this work, but I can't find any explanation for those cryptic map, imap settings. What is the underlying issue here, and how can I fix it? Thanks!

  • Monitor randomly shutting down, computer accepting no input, need to restart to get working

    - by Sebastian Lamerichs
    First off, spec list: OS: Windows 7 Ultimate 64-bit SP1 CPU: i7-4820k @ 3.7GHz (stock) GPU: Two 3GB Radeon HD 7970s @ 1.05GHz Mobo: AsRock X79 Extreme6 HDD: 2TB Seagate Barracuda 7200rpm RAM: 16GB quad-channel Kingston 1600MHz PSU: Antec HCG 900W Monitors: Acer S220HQL 1920x1080 + ViewSonic VA2251 1920x1080. Plugged into different GPUs. My problem is that, on a daily-ish basis, my monitors will turn off and not turn back on. My computer will still be running, GPU/CPU/case fans all still going, but the monitors will not turn back on. Additionally, it seems to cease all network activity. It doesn't seem to log any errors at all. I've verified that this is not a monitor issue, as when I press the num/caps/scroll lock buttons on my keyboard, the lights don't change, so the computer is clearly not accepting input. I have noticed a few other people on the internet with this problem, and some have claimed that it was solved by disabling PCI-Express Link State Power Management, but the issue still occurs for me after this. Whilst my CPU and GPUs both run at 100% 24/7, the temperatures are certainly not at dangerous levels, with the CPU averaging 65°C and the GPUs at 70°C and 78°C average. All components are brand new. I have tried forcing MSI Afterburner to start when Windows starts and to force a constant voltage, as this fixed the issue for a few days for another user, but he reported back saying that it had stopped working properly again, so I'm not putting too much faith in this working. Many people have said to adjust display sleep mode settings, but this will clearly not work, as the keyboard lights would still work if the monitors were the issue. The closest I can get to a log file for this issue is the following Folding@Home logs: 14:45:21:WU01:FS00:0x17:Completed 1120000 out of 2000000 steps (56%) 14:46:43:WU00:FS01:0x17:Completed 480000 out of 2000000 steps (24%) 14:46:49:WU01:FS00:0x17:Completed 1140000 out of 2000000 steps (57%) 14:48:30:WU01:FS00:0x17:Completed 1160000 out of 2000000 steps (58%) 14:49:55:WU01:FS00:0x17:Completed 1180000 out of 2000000 steps (59%) As you can see, the second GPU (FS01) stops computation approximately three and a half minutes before the issue occurs (it should be completing 1% every 80-120 seconds), and the first GPU (FS00) continues for a few minutes more before the logs just end. As far as I can tell, the computer has a network failure at the time the first GPU stops working, the latest IRC message I received from this time was at 14:47:58. That being said, there could have just not been any messages between then and 14:50:00, so I'm going to be connecting a laptop to the same bouncer to double-check if it happens again. The GPUs functioned perfectly well in another computer for a significant period of time, so I'm fairly confident that they aren't the issue, which means that this is being caused by either software or the motherboard, or possibly RAM. I really hope it's software. I heard from a forum board that there was a patch from Microsoft that fixed this problem, but "I've forgot which KB it was or the google search terms I used to find the patch, LOL.", so that's not much help. Haven't seen it mentioned by anyone else on about a dozen threads about this issue either. The computer is plugged in via a surge-protected power board, and I've run several other computers and pieces of hardware through it with no issues, so that is not the cause. I have just set the hard disk to never turn off, although I don't believe that that will solve the issue. Strangely, this has only happened when I'm not at the computer (which is actually a minority of the time). Until today it had only happened when I had not been actively using the computer for 6 hours, but today it happened within 10-30 minutes of me last using the computer actively. I have enabled file logging from MSI Afterburner, so hopefully this will shed some light on the issue, but I'm not too optimistic. I've heard that it could be a motherboard problem, but I figured I should ask around before RMAing it. Any help?

  • IE not triggering keyboard event on a form with ONE FIELD

    - by raj
    I'm seeing my Friend's code here... <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> </form> </BODY> </HTML> and when he tried entering a value in the textbox and pressed enter, it did not call the detectEvent(). I said, it'll always call onSubmit on enter button..... and he surprised me, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> <p> Field1 <input type="text" id="text2"/> </p> </form> </BODY> </HTML> Now press enter, The function gets called..... Why so!? Why onKeyUp not called on forms with just one field.!!! am i missing something?

  • What is the proper way to code a read-while loop in Scala?

    - by ARKBAN
    What is the "proper" of writing the standard read-while loop in Scala? By proper I mean written in a Scala-like way as opposed to a Java-like way. Here is the code I have in Java: MessageDigest md = MessageDigest.getInstance( "MD5" ); InputStream input = new FileInputStream( "file" ); byte[] buffer = new byte[1024]; int readLen; while( ( readLen = input.read( buffer ) ) != -1 ) md.update( buffer, 0, readLen ); return md.digest(); Here is the code I have in Scala: val md = MessageDigest.getInstance( hashInfo.algorithm ) val input = new FileInputStream( "file" ) val buffer = new Array[ Byte ]( 1024 ) var readLen = 0 while( readLen != -1 ) { readLen = input.read( buffer ) if( readLen != -1 ) md.update( buffer, 0, readLen ) } md.digest The Scala code is correct and works, but feels very un-Scala-ish. For one it is a literal translation of the Java code, taking advantage of none of the advantages of Scala. Further it is actually longer than the Java code! I really feel like I'm missing something, but I can't figure out what. I'm fairly new to Scala, and so I'm asking the question to avoid falling into the pitfall of writing Java-style code in Scala. I'm more interested in the Scala way to solve this kind of problem than in any specific helper method that might be provided by the Scala API to hash a file. (I apologize in advance for my ad hoc Scala adjectives throughout this question.)

  • Programming style question on how to code functions

    - by shawnjan
    Hey all! So, I was just coding a bit today, and I realized that I don't have much consistency when it comes to a coding style when programming functions. One of my main concerns is whether or not its proper to code it so that you check that the input of the user is valid OUTSIDE of the function, or just throw the values passed by the user into the function and check if the values are valid in there. Let me sketch an example: I have a function that lists hosts based on an environment, and I want to be able to split the environment into chunks of hosts. So an example of the usage is this: listhosts -e testenv -s 2 1 This will get all the hosts from the "testenv", split it up into two parts, and it is displaying part one. In my code, I have a function that you pass it in a list, and it returns a list of lists based on you parameters for splitting. BUT, before I pass it a list, I first verify the parameters in my MAIN during the getops process, so in the main I check to make sure there are no negatives passed by the user, I make sure the user didnt request to split into say, 4 parts, but asking to display part 5 (which would not be valid), etc. tl;dr: Would you check the validity of a users input the flow of you're MAIN class, or would you do a check in your function itself, and either return a valid response in the case of valid input, or return NULL in the case of invalid input? Obviously both methods work, I'm just interested to hear from experts as to which approach is better :) Thanks for any comments and suggestions you guys have!

  • Validation problem with a 'JotForm' template

    - by Thomas
    A client sent me a form template they had created using jotform.com to implement on their wordpress site. The form template is supposed to hide part of the form until the user clicks the 'next' button. At which point a script is supposed to validate all of the input fields the user has presumably filled out and then display the rest of the form. While I have successfully managed to get the form to display the next part of the form when the user clicks 'next', it fails to validate the input fields. Its kind of difficult to explain without a huge block of text so it is probably easier to show you: The original working template that the customer sent me: http://www.loftist.com/jotform/List_Your_Loft.html The problem child: http://www.loftist.com/?page_id=78 If you just click on one of the input fields and then click elsewhere on the page, the input fields successfully return a validation error message and prevent the user from clicking on the 'next' button. However, if you simply click on the next button than the next set of fields get displayed. Any thoughts? What am I doing wrong here? Im convinced this must be a really simple problem but Im not sure what it could be....

  • inheritance confusion. Adding a special class for making errors obvious on form validation

    So I've got a form...

But it doesn't seem to inherit right. What am I doing wrong?

  • FileInput Help/Advice

    - by user559142
    I have a fileinput class. It has a string parameter in the constructor to load the filename supplied. However it just exits if the file doesn't exist. I would like it to output a message if the file doesn't exist - but not sure how.... Here is the class: public class FileInput extends Input { /** * Construct <code>FileInput</code> object given a file name. */ public FileInput(final String fileName) { try { scanner = new Scanner(new FileInputStream(fileName)); } catch (FileNotFoundException e) { System.err.println("File " + fileName + " could not be found."); System.exit(1); } } /** * Construct <code>FileInput</code> object given a file name. */ public FileInput(final FileInputStream fileStream) { super(fileStream); } } And its implementation: private void loadFamilyTree() { out.print("Enter file name: "); String fileName = in.nextLine(); FileInput input = new FileInput(fileName); family.load(input); input.close(); }

  • Integrating PayMill: The token filled input field is not created, error "field_invalid_amount"

    - by automatix
    I'm implementing the Credit Card Payment form of PayMill according to the Payment Form docu. So I copied the JS from the Bridge docu page and the form from the Payment Form docu page. But no token is created. When I try to debug the JS and add console.info(error.apierror); into the paymillResponseHandler(...) function, I get the error code: field_invalid_amount. According to the support page There are three possible reasons for this error message: no amount value was provided numbers were rounded wrong delimiter symbol But the amuont is provided and I've already tried different delimiter symbols. What "numbers were rounded" means, is not clear. What can be the problem and how to fix this issue?

  • Easy line break removal from text fields and/or selections

    I'm looking for a tool that allows me to easily re-wrap text (i.e. remove line breaks, but not paragraph breaks from a text selection or the current text field that is being edited), and that works at least with text fields in my browser (Chrome) and on Windows. Bonus points for anything that works outside the browser, and that works in-place (i.e. that doesn't require copy-pasting the text through a separate window or using something like http://www.textfixer.com/tools/remove-line-breaks.php) Browser extensions, GreaseMonkey scripts or applications that also work on Linux and/or Mac (or even better, that are multi-platform) are all welcomed. Here is an example of how the tool should behave. If I have the following in a text field: This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com. This is a test for SuperUser.com I'd like to have an easy tool that allows me to, for example, select the text, and with a keyboard shortcut convert it to: This is a test for SuperUser.com.

  • Swapping Function (Fn) and Control (Ctrl) Keys on Lenovo ThinkPad W500

    - by Howiecamp
    I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others! See: How can I switch the function and control keys on my laptop? and Intercepting the Fn key on laptops) Numerous folks indicate that Windows doesn't register the Fn key as a keypress but using Mihov ASCII Master 2.0, that gives the ASCII value of a keypress, I see the Fn key returning FF (perhaps FF in this case means 'not registered'). I also see that keys like Ctrl register with one ASCII code when pressed alone and another when pressed in combo with another key. Fn will only register when pressed alone, so Windows definitely isn't seeing the combo. This took a solution like AutoHotKey off the table. I ran KeyTweak (which shows you the hardware scan codes of a keypress and the Fn key registerd as 57443). Using this program I remapped Fn to the Ctrl key; this worked perfectly. However, I suspect that because of the issue in #1, the combo of, for example, Fn + C did not execute a copy. Short of retraining my pinky I'm actually considering removing the keyboard and resoldering the connections to swap those keys. I'd love to get some input as to the root technical issue(s) and possible solutions here.

    I'd like to swap the Fn and Ctrl keys on my ThinkPad W500 (like many others!). I wanted to comment on http://superuser.com/questions/35228/how-can-i-switch-the-function-and-control-keys-on-my-laptop and StackOverflow question 514781 (please Google it because I don't have enough rep to include 2 hyperlinks) but I don't have enough rep to do so to comment. Numerous folks (in both the above questions and on other Google searches) indicate that Windows doesn't register the Fn key as a keypress but using a tool that gives the ASCII value of a keypress (visit www mihov com / eng / am.html) I see the Fn key returning FF (perhaps FF in this case means 'not registered').

  • Linux RFID reader HID Device not matching driver

    - by blietaer
    Hello, I got a RFID reader (GigaTek PCR330A-00) that is meant to be recognized under linux/windows as a (Human Interface Device) keyboard/USB. I hate to say this but it is working as a charm under Win7 but not "really" under Linux. Under Debian-like distros (x/k/Ubuntu, Debian,..), or Gentoo, or... I just can't have the device working at all: the device scan well (it has its USB 5V, so it is happy/beeping/blinking) something happened in the dmesg, but no immediate screen display of the RFID Tag code as expected (and seen under win7) Support is claiming it is ok under RHEL or SLED "enterprises" distros... and I must admit I saw it working under a RHEL4... I tried stealing the driver but did not succeed having my reader working... My question is thus double: 1./ How can I hack the kernel to add support to my device (simply register PID/VID?) ? 2./ What is different at all in a "enterprise" proprietary distro? how can I re-use it? Thank you for any hint/help. Cheers,

  • Vanishing Windows Desktop Shortcut Keys

    - by Henry Keiter
    The Situation Like you, I have many applications that I like to open. I've set up keyboard shortcuts for the most common, by placing a link on the desktop and setting its Shortcut Key property: This is all fine and dandy, most of the time. When I want to bring up the GIMP, I press Ctrl+Alt+G and the GIMP launches. Lovely. The Problem Sometimes--perhaps once a month per desktop shortcut--the shortcut key assignment simply vanishes. I press Ctrl+Alt+G and nothing happens, so I go check the shortcut and see that lo and behold: nothing is there. This happens regularly to all my shortcuts (not all at once). It doesn't matter what keys I assign, and there doesn't seem to be any correlation with particular applications being open or anything of that sort. This has happened on every Windows XP machine I've ever used with any regularity. Obviously what makes this issue particularly obnoxious is that it's not easily reproducible. I have searched long and hard for a solution for (or at least acknowledgement of) this problem, to no avail, so hopefully you guys know something that I don't. I did find this question, where the answers are all basically "use a third-party app", but as far as I could tell that was a slightly different issue, related to Explorer being busy. If the solution for this turns out to be the same, fine, but I'd prefer a native fix if at all possible. Note: I've tagged this with Windows in general because I seem to remember it happening on Windows 7 as well as XP, but I rarely notice it because I use the start-menu search in preference to desktop shortcuts.

  • Coming from Win XP to 7 and having new accessibility software problems

    - by Anonymous Jones
    I just switched from Windows XP Pro SP3 (32bit) to Windows 7 Ultimate (32bit) on a new PC. Now, both the new onscreen keyboard and a utility for sending mouse clicks are being problematic. The problem with 7's OSK is that some things I type only work intermittently or just dodgily. Like Alt+Tab with multiple Tabs, other Alt/Ctrl/Shift/Win key combinations, and the context menu key. Sometimes apps will not take focus for input at all. I use the OSK it in 'hover' mode, on 0,5 seconds. The clicking tool is Point-N-Click, which sends clicks when I dwell anywhere for 1.25 seconds with the mouse pointer. http://www.polital.com/pnc/ The problem with it is that sometimes it fails to click. Most often this happens in some of the control panel sections, on the taskbar, and when UAC pops up. It seems to occur in conjunction with OSK usage a bit too, I think. I'm using an Administrator account. DEP and UAC settings are default. What can I do to fix or work around either of these problems? I'm disabled so this really is killing usability.

  • How can I make my Super keys (Windows Key) behave more like Ctrl/Alt/Shift in Linux

    - by deltaray
    After using the Ctrl + "arrow keys" for 13 years to switch virtual desktops in X windows, I've been convinced recently to change to using the Super keys instead (the windows key and the context menu key, which I've remapped). This all works fine for the most part. However, something is still picking up the key events that these keys are sending as if they are a normal alphanumeric like key. For example, I first noticed this in Google Docs spreadsheet that if I press the windows key alone over top of a cell, that it starts editing that cell. It doesn't insert anything, it just sends a key event that Firefox sees and starts editing the cell. This caused problems on a collaborative document I was working on as the way Google docs works, it led to me accidentally erasing the data in a few fields before I realised what was going on. I like using the super keys, but I want them to behave more like a Ctrl or Alt key does in that its a modifier key and doesn't send anything until a second key is pressed. My setup is the following: Ubuntu 10.10 XFCE 4 Microsoft Natural Ergo 4000 keyboard (with the logo scratched out) The following is my .Xmodmap file: remove Lock = Caps_Lock keycode 66 = Escape ! The below maps my other windows context menu key. keycode 135 = Super_R Edit: As requested, here is the relevant output from xev for a keypress and keyrelease of my Super_L (left windows key) KeyPress event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849342, (177,174), root:(182,228), state 0x10, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False KeyRelease event, serial 34, synthetic NO, window 0x8200001, root 0x15d, subw 0x0, time 2428849430, (177,174), root:(182,228), state 0x50, keycode 133 (keysym 0xffeb, Super_L), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False

  • (PHP) Validation, Security and Speed - Does my app have these?

    - by Devner
    Hi all, I am currently working on a building community website in PHP. This contains forms that a user can fill right from registration to lot of other functionality. I am not an Object-oriented guy, so I am using functions most of the time to handle my application. I know I have to learn OOPS, but currently need to develop this website and get it running soon. Anyway, here's a sample of what I let my app. do: Consider a page (register.php) that has a form where a user has 3 fields to fill up, say: First Name, Last Name and Email. Upon submission of this form, I want to validate the form and show the corresponding errors to the users: <form id="form1" name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>"> <label for="name">Name:</label> <input type="text" name="name" id="name" /><br /> <label for="lname">Last Name:</label> <input type="text" name="lname" id="lname" /><br /> <label for="email">Email:</label> <input type="text" name="email" id="email" /><br /> <input type="submit" name="submit" id="submit" value="Submit" /> </form> This form will POST the info to the same page. So here's the code that will process the POST'ed info: <?php require("functions.php"); if( isset($_POST['submit']) ) { $errors = fn_register(); if( count($errors) ) { //Show error messages } else { //Send welcome mail to the user or do database stuff... } } ?> <?php //functions.php page: function sql_quote( $value ) { if( get_magic_quotes_gpc() ) { $value = stripslashes( $value ); } else { $value = addslashes( $value ); } if( function_exists( "mysql_real_escape_string" ) ) { $value = mysql_real_escape_string( $value ); } return $value; } function clean($str) { $str = strip_tags($str, '<br>,<br />'); $str = trim($str); $str = sql_quote($str); return $str; } foreach ($_POST as &$value) { if (!is_array($value)) { $value = clean($value); } else { clean($value); } } foreach ($_GET as &$value) { if (!is_array($value)) { $value = clean($value); } else { clean($value); } } function validate_name( $fld, $min, $max, $rule, $label ) { if( $rule == 'required' ) { if ( trim($fld) == '' ) { $str = "$label: Cannot be left blank."; return $str; } } if ( isset($fld) && trim($fld) != '' ) { if ( isset($fld) && $fld != '' && !preg_match("/^[a-zA-Z\ ]+$/", $fld)) { $str = "$label: Invalid characters used! Only Lowercase, Uppercase alphabets and Spaces are allowed"; } else if ( strlen($fld) < $min or strlen($fld) > $max ) { $curr_char = strlen($fld); $str = "$label: Must be atleast $min character &amp; less than $max char. Entered characters: $curr_char"; } else { $str = 0; } } else { $str = 0; } return $str; } function validate_email( $fld, $min, $max, $rule, $label ) { if( $rule == 'required' ) { if ( trim($fld) == '' ) { $str = "$label: Cannot be left blank."; return $str; } } if ( isset($fld) && trim($fld) != '' ) { if ( !eregi('^[a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.([a-zA-Z]{2,4})$', $fld) ) { $str = "$label: Invalid format. Please check."; } else if ( strlen($fld) < $min or strlen($fld) > $max ) { $curr_char = strlen($fld); $str = "$label: Must be atleast $min character &amp; less than $max char. Entered characters: $curr_char"; } else { $str = 0; } } else { $str = 0; } return $str; } function val_rules( $str, $val_type, $rule='required' ){ switch ($val_type) { case 'name': $val = validate_name( $str, 3, 20, $rule, 'First Name'); break; case 'lname': $val = validate_name( $str, 10, 20, $rule, 'Last Name'); break; case 'email': $val = validate_email( $str, 10, 60, $rule, 'Email'); break; } return $val; } function fn_register() { $errors = array(); $val_name = val_rules( $_POST['name'], 'name' ); $val_lname = val_rules( $_POST['lname'], 'lname', 'optional' ); $val_email = val_rules( $_POST['email'], 'email' ); if ( $val_name != '0' ) { $errors['name'] = $val_name; } if ( $val_lname != '0' ) { $errors['lname'] = $val_lname; } if ( $val_email != '0' ) { $errors['email'] = $val_email; } return $errors; } //END of functions.php page ?> OK, now it might look like there's a lot, but lemme break it down target wise: 1. I wanted the foreach ($_POST as &$value) and foreach ($_GET as &$value) loops to loop through the received info from the user submission and strip/remove all malicious input. I am calling a function called clean on the input first to achieve the objective as stated above. This function will process each of the input, whether individual field values or even arrays and allow only tags and remove everything else. The rest of it is obvious. Once this happens, the new/cleaned values will be processed by the fn_register() function and based on the values returned after the validation, we get the corresponding errors or NULL values (as applicable). So here's my questions: 1. This pretty much makes me feel secure as I am forcing the user to correct malicious data and won't process the final data unless the errors are corrected. Am I correct? Does the method that I follow guarantee the speed (as I am using lots of functions and their corresponding calls)? The fields of a form differ and the minimum number of fields I may have at any given point of time in any form may be 3 and can go upto as high as 100 (or even more, I am not sure as the website is still being developed). Will having 100's of fields and their validation in the above way, reduce the speed of application (say upto half a million users are accessing the website at the same time?). What can I do to improve the speed and reduce function calls (if possible)? 3, Can I do something to improve the current ways of validation? I am holding off object oriented approach and using FILTERS in PHP for the later. So please, I request you all to suggest me way to improve/tweak the current ways and suggest me if the script is vulnerable or safe enough to be used in a Live production environment. If not, what I can do to be able to use it live? Thank you all in advance.
