  • cd ~ dumps me in a seemingly empty directory

    - by Davidos
    This is on a Linux mint box. I'm told everywhere to use the command cd ~ To switch to the root directory before doing some command line magic. For some reason though, it dumps me in a directory named ~ where ls gives nothing and I can't get back to my home directory; I have to restart the terminal session to get out of the empty root directory. I'm positive that everything is just hidden to me, but even as a super-user I can't get the folders to show themselves. I usually just fall back to using a graphical file browser to roam those forbidden files, but I've recently just been shut out of my root directory, and the machine refuses to allow me to change the permissions on the stupid thing even when I type the root password in. It may just be some over-rigorous end-user shielding on the part of the mint team, but it's getting to be really frustrating now.

  • Setting nested object to null when combobox has empty value

    - by Javi
    Hello, I have a Class which models a User and another which models his country. Something like this: public class User{ private Country country; //other attributes and getter/setters } public class Country{ private Integer id; private String name; //other attributes and getter/setters } I have a Spring form where I have a combobox so the user can select his country or can select the undefined option to indicate he doen't want to provide this information. So I have something like this: <form:select path="country"> <form:option value="">-Select one-</form:option> <form:options items="${countries}" itemLabel="name" itemValue="id"/> </form:select> In my controller I get the autopopulated object with the user information and I want to have country set to null when the "-Select one-" option has been selected. So I have set a initBinder with a custom editor like this: @InitBinder protected void initBinder(WebDataBinder binder) throws ServletException { binder.registerCustomEditor(Country.class, "country", new CustomCountryEditor()); } and my editor do something like this: public class CustomCountryEditor(){ @Override public String getAsText() { //I return the Id of the country } @Override public void setAsText(String str) { //I search in the database for a country with id = new Integer(str) //and set country to that value //or I set country to null in case str == null } } When I submit the form it works because when I have country set to null when I have selected "-Select one-" option or the instance of the country selected. The problem is that when I load the form I have a method like the following one to load the user information. @ModelAttribute("user") public User getUser(){ //loads user from database } The object I get from getUser() has country set to a specific country (not a null value), but in the combobox is not selected any option. I've debugged the application and the CustomCountryEditor works good when setting and getting the text, thoughgetAsText method is called for every item in the list "countries" not only for the "country" field. Any idea? Is there a better way to set null the country object when I select no country option in the combobox? Thanks

  • How to set resolution higher than maximum shown?

    - by Olivier Lalonde
    I just bought an external monitor for my laptop (Asus VH242H) but cannot set its resolution to anything higher than 1600x900. I tried both from System/Administration/Monitors and the ATI Catalyst Control Center. There was a CD that came with the monitor but it only contains a Windows installer. According to the monitor's specifications: 23.6” 16:9 widescreen with 1920×1080 resolution enables borderless Full HD 1080p full-screen video display. My graphic card is an ATI Mobility Radeon HD 4670 and the monitor is currently connected to my laptop with a VGA cable. How can I set my external monitor to its maximum resolution?

  • How to set up an informational interview?

    I've heard a lot about informational interviews, but don't have the slightest idea how to actually set one up or run one effectively. I work as an SDET (SDE in Test) in an area with lots of great technical companies, and would like to have a better understanding of how different companies do testing. I have three sub-questions: Who would I get in contact with to set up informational interviews at a company that I'd like to learn about? How can I make sure the time is productive? And, how do I keep the interview from being a burden to the employee(s) whom I speak with?

  • ubuntu-overlay-scrollbars set to false shows no arrows in several cases

    - by Willem van Gerven
    I'm running 12.04, and prefer the more conservative style "normal" scrollbars over the overlay scrollbars. I have set them to false in the terminal: gsettings set org.gnome.desktop.interface ubuntu-overlay-scrollbars false However after doing so, with some apps (e.g. Nautilus, Document Viewer) my scrollbars only view a vertical bar, but no arrows on the top and bottom to scroll up and down. With some programs these are shown though, for instance Gummi and Texmaker. It would make a big difference (for instance when having to scroll pdf documents containing several hundreds of pages) to have those arrows reinstated. Is there any way to make this work?

  • Can't set proper resolution with a Geforce 520

    - by D0X
    I installed the 12.04 LTS but cannot get my two monitors working. The latest nvidia-current drivers installed, but i just cant set proper resolution. My card is a geforce 520 1 DVI 1 VGA. With the nvidia drivers installed i can set the DVI monitor to 1600x1200 but the VGA no further than 1360x768 (with nvidia-settings). Without the nvidia driver (using the nouveau) it doesn't work either. This same issue i had with 11.10 and i had high hopes for 12.04.

  • making "xwacom set" changes permanent

    - by Philippe
    On my Thinkpad X220 Tablet the touch-finger works flawlessly but the pen is terribly miscalibrated. The calibration tool in System settings - Wacom tablet does not work. Instead, whenever I wan't to use the pen I first need to sudo xsetwacom set 'Wacom ISDv4 E6 Pen stylus' Area 0 0 27760 15690 These changes do not remain permanent. That is, after every reboot they are gone. How can I make the change permanent - I'm not looking for a startup scrip, I'd like to set the right area once for all. Any idea?

  • Rythmbox library set to: multiple locations and no way to edit/change

    - by Pierre
    I previously set Rhythmbox to include a few different locations. Now following changes to my directory structure, I'd like to reflect these changes in Rhythmbox. But when I go to "Library Location", I see "Multiple locations Set" and I can only add to the list; no way to edit/remove. I Googled this problem and the only relevant results I get date back to 2006, probably referring to a previous version of Rhythmbox and specifying components/locations that I can't find on my system. Give a look at the documentation...kind of minimal. Any clues? Ubuntu 12.04 Rhythmbox 2.96

  • php array strip_tags and unset

    - by teo6389
    hello everybody i have a question regarding strip_tags function. i have an html document like that. <!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>Untitled Document</title> </head> <body> <p>er</p> </body> </html> and this php script <?php $file = "ht.html"; $fp = fopen($file, "r"); $data = fread($fp, filesize($file)); fclose($fp); $output = str_replace("\t|\t", "|", $data); $outputline = explode("\n", $output); $lexeisline=count($outputline); for ($i = 0; $i < $lexeisline; $i++){ $outputline[$i]=strip_tags($outputline[$i]); if (empty($outputline[$i])){ unset($outputline[$i]); } } $outputline = array_values($outputline); $lexeisline=count($outputline); echo "<p>"; for ($i = 0; $i < $lexeisline; $i++){ echo ($outputline[$i])."<br />"; } echo "</p>"; ?> the problem is that it does not unset the empty vars(which are returned from the strip_tags) and echos something like this. does the following means that it echos empty strings? any opinion or help will be very appreciated. Thanx in advance <p> <br /> <br /> <br /> <br />Untitled Document <br /> <br /> <br />er <br /> <br /></p> @phpmeh Array ( [0] => [1] => [2] => [3] => [4] => Untitled Document [5] => [6] => [7] => er [8] => )

  • Symfony - admin - FormFilter - is empty - i18n

    - by Mailo
    Hi, we are in admin generator in filters in field. What is the most clearest way to translate is empty label under form fields? I've solve it by own setWidgets and setWidgets in BaseFormFilterDoctrine witch extend the parent methods by translating that is empty( empty_label ). setWidgets - translate all *empty_label*s in form filter( for base filter class ) setWidget - translate *empty_label* for one filter field( for the extending filter class ) It works, but i think it's nasty. I am looking for something more clean

  • My neural network gets "stuck" while training. Is this normal?

    - by Vivin Paliath
    I'm training a XOR neural network via back-propagation using stochastic gradient descent. The weights of the neural network are initialized to random values between -0.5 and 0.5. The neural network successfully trains itself around 80% of the time. However sometimes it gets "stuck" while backpropagating. By "stuck", I mean that I start seeing a decreasing rate of error correction. For example, during a successful training, the total error decreases rather quickly as the network learns, like so: ... ... Total error for this training set: 0.0010008071327708653 Total error for this training set: 0.001000750550254843 Total error for this training set: 0.001000693973929822 Total error for this training set: 0.0010006374037948094 Total error for this training set: 0.0010005808398488103 Total error for this training set: 0.0010005242820908169 Total error for this training set: 0.0010004677305198344 Total error for this training set: 0.0010004111851348654 Total error for this training set: 0.0010003546459349181 Total error for this training set: 0.0010002981129189812 Total error for this training set: 0.0010002415860860656 Total error for this training set: 0.0010001850654351723 Total error for this training set: 0.001000128550965301 Total error for this training set: 0.0010000720426754587 Total error for this training set: 0.0010000155405646494 Total error for this training set: 9.99959044631871E-4 Testing trained XOR neural network 0 XOR 0: 0.023956746649767453 0 XOR 1: 0.9736079194769579 1 XOR 0: 0.9735670067093437 1 XOR 1: 0.045068688874314006 However when it gets stuck, the total errors are decreasing, but it seems to be at a decreasing rate: ... ...

Is my network getting stuck in a local minima instead of a global minima?

  • Adding empty string to RadComboBox

    - by icemanind
    Guys, I have a webpage that has a Telerik RadComboBox on the page. One of the properties of this ComboBox is EmptyMessage, which fills the combobox with a message when an item is not selected. I am binding my combobox to a datasource at runtime and for some reason, it wipes this EmptyMessage away. Is there a way to keep my data items in tact and have the empty message there too? And default it to the empty message?
