  • Can I get the amount of time for which a key is pressed on a keyboard

    - by Adi
    Dear all, I am working on a project in which I have to develop bio-passwords based on user's keystroke style. Suppose a user types a password for 20 times, his keystrokes are recorded, like holdtime : time for which a particular key is pressed. digraph time : time it takes to press a different key. suppose a user types a password " COMPUTER". I need to know the time for which every key is pressed. something like : holdtime for the above password is C-- 200ms O-- 130ms M-- 150ms P-- 175ms U-- 320ms T-- 230ms E-- 120ms R-- 300ms The rational behind this is , every user will have a different holdtime. Say a old person is typing the password, he will take more time then a student. And it will be unique to a particular person. To do this project, I need to record the time for each key pressed. I would greatly appreciate if anyone can guide me in how to get these times. Editing from here.. Language is not important, but I would prefer it in C. I am more interested in getting the dataset.

  • ClassNotFoundException: org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider

    - by Kiva
    I try to start an Google appengine application in my eclipse. I have the Google plugin and I set the sdk for my application. But, when I start this one, I get the following error: java.lang.ClassNotFoundException: org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider However, this class is present in the sdk which is present in my classpath. Why Appengine doesn't find this class ? Thanks.

  • There is Hidden Value in a Nofollow Link

    Not to be quickly discounted, every carefully planned link building campaign should have a fair representation; of nofollow links. Although they do not pass on any link power, website credibility or result influence, they do work tirelessly to associate your website; with carefully selected anchor text.

  • WPF validation on Enter Key Up

    - by Martin
    I'm trying to validate a UI change when Enter key is pressed. The UI element is a textbox, which is data binded to a string. My problem is that the data binding hasn't updated TestText when Enter key is Up. It is only updated when I press the button which brings up a message box. /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window, INotifyPropertyChanged { String _testText = new StringBuilder("One").ToString(); public string TestText { get { return _testText; } set { if (value != _testText) { _testText = value; OnPropertyChanged("TestText"); } } } public Window1() { InitializeComponent(); myGrid.DataContext = this; } private void OnPropertyChanged(string property) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(property)); } } public event PropertyChangedEventHandler PropertyChanged; private void onKeyUp(object sender, KeyEventArgs e) { if (e.Key != System.Windows.Input.Key.Enter) return; System.Diagnostics.Trace.WriteLine(TestText); } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show(TestText); } } Window XAML: Window x:Class="VerificationTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" KeyUp="onKeyUp" TextBox XAML: TextBox Name="myTextBox" Text="{Binding TestText}" Button XAML: Button Name="button1" Click="button1_Click"

  • Different configurations for ssh client depending on ip address or hostname

    - by John Smith Optional
    I have this in my ~/.ssh/config directory: Host 12.34.56.78 IdentityFile ~/.ssh/my_identity_file When I ssh to 12.34.56.78, everything works fine. I'm asked for the passphrase for "my_identity_file" and I can connect to the server. However, sometimes I'd also like to ssh to another server. But whatever the server, if I do: ssh [email protected] I'm also asked for the passphrase for "my_identity_file" (even though the server has a different ip address). This is very annoying because I don't have the public key for this file set up on all my servers. I'd like to connect to this other server (an old shared hosting account) with a password, and now I cant. How do I manage to use the key authentication only with one server, and keep using password by default for servers that aren't listed in my ~/.ssh/config ? Thanks for your help.

    I am making a 2D game in javascript/ajax, that will be using data stored in mysql database. Every user have got his own "area" made of small squares that can have some values. But I have no idea, how to store values of each square in mysql, when each user can have area with different width or height. Do you have some idea?

  • The best DPI value to let you work nicely [closed]

    - by user827992
    I'm probably about to buy a laptop, unfortunely they all have glare screen, even the "premium" device, the actual offer just differentiate on 2-3 variations about DPI and display resolution; considering that i would like a 13" laptop, what can be the best resolution? I was looking for a 4:3 but this days they are all cheap-made so i do not think that something expensive to produce like a 4:3 is on the market. on the 13" laptops i see that basically there are available 3 kinds of displays: 1366x768 ( a 16:9 ratio ) 1400x900 ( a 16:10 ratio ) 1600x900 ( a 16:9 ratio ) Honestly i'm asking for an advice because i do not like this things, not even one of them, but this is the market today, i was looking for some old-style laptop with good plastics, a 4:3 ratio or 5:4 or something like that and a true matte finish with an higher resolution compared to what you could find in the old laptops. Since programming involves the presence of many text character on the screen it's a good thing to choose the one with the highest DPI/PPI ?

  • How can I make smoother upwards/downwards controls in pygame?

    - by Zolani13
    This is a loop I use to interpret key events in a python game. # Event Loop for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: my_speed = -10; if event.key == pygame.K_d: my_speed = 10; if event.type == pygame.KEYUP: if event.key == pygame.K_a: my_speed = 0; if event.key == pygame.K_d: my_speed = 0; The 'A' key represents up, while the 'D' key represents down. I use this loop within a larger drawing loop, that moves the sprite using this: Paddle1.rect.y += my_speed; I'm just making a simple pong game (as my first real code/non-gamemaker game) but there's a problem between moving upwards <= downwards. Essentially, if I hold a button upwards (or downwards), and then press downwards (or upwards), now holding both buttons, the direction will change, which is a good thing. But if I then release the upward button, then the sprite will stop. It won't continue in the direction of my second input. This kind of key pressing is actually common with WASD users, when changing directions quickly. Few people remember to let go of the first button before pressing the second. But my program doesn't accommodate the habit. I think I understand the reason, which is that when I let go of my first key, the KEYUP event still triggers, setting the speed to 0. I need to make sure that if a key is released, it only sets the speed to 0 if another key isn't being pressed. But the interpreter will only go through one event at a time, I think, so I can't check if a key has been pressed if it's only interpreting the commands for a released key. This is my dilemma. I want set the key controls so that a player doesn't have to press one button at a time to move upwards <= downwards, making it smoother. How can I do that?

  • Multiple public keys for one user

    - by Russell
    This question is similar to SSH public key authentication - can one public key be used for multiple users? but it's the other way around. I'm experimenting on using ssh so any ssh server would work for your answers. Can I have multiple public keys link to the same user? What are the benefits of doing so? Also, can different home directories be set for different keys used (all of which link to the same user)? Please let me know if I'm unclear. Thanks.

  • Indexes and multi column primary keys

    - by David Jenings
    Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

  • 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!

  • Understanding the Value of a DMOZ Submission

    The Open Directory Project (DMOZ) data powers the core directory services for many of the Internet's most influencial search engines and portals. However, Matt Cutts once said: "if you can't get into Dmoz, I wouldn't necessarily worry about it. There are a lot of other great places to get links across the web."

  • Quantify value for management

    - by nivlam
    We have two different legacy systems (window services in this case) that do exactly the same thing. Both of these systems have small differences for the different applications they serve. Both of these system's core functionality lies within a shared library. Most of the time, the updates occur in the shared library and we simply deploy the updated library to both of these systems. The systems themselves rarely change. Since both of these systems do essentially the same thing, our development team would like to consolidate these two systems into a single service. What can I do to convince management to allocate time for such a task? Some of the points I've noted are: Easier maintenance Decrease testing/QA time Unfortunately, this isn't enough. They would like us to provide them with hard numbers on the amount of hours this will save in the future and how this will speed up future development. Since most of the work is done in the shared library and the systems themselves never change, it's hard for us to quantify how many hours this will save. What kind of arguments can I make to justify the extra work to consolidate these systems?

  • seo value of duplicating content externally

    - by Don
    I run a website that includes a blog which was hand-coded by myself and is hosted on the same domain. My partner in this endeavour thinks it would be a good idea to open up a blogger/wordpress blog and duplicate the on-site blog on this off-site blog. AFAIK the main reason for doing this is the SEO benefits of the inbound links that this off-site blog will create. I think this is a bad idea, because: Effectively what we're doing is creating a (very small scale) link farm We're more likely to be punished than rewarded (in SEO terms) for duplicating our content across domains This introduces a problem of synchronising our content across domains. For example, if a blog post is edited on the on-site blog, then ideally the off-site blog should be similarly updated. I know very little about SEO, so would be interested to hear what more informed readers have to say.

  • App store for the PC?

    - by Chris
    So I've spent a lot of time making an iPhone game and have recently realized that I don't have to limit myself to just Apple - I know there are app stores for Palm and Android, but does anybody know of a good "app store" for the plain old PC? I would like to have one where individual developers can publish an app and not have to worry about all the billing and piracy issues!
