![]() Spritz yeni bir hızlı okuma sistemi ve bir yazılım olarak çalışıyor. Bu yazılım sayesinde okuma sırasındaki göz hareketleriniz minimuma iniyor ve daha hızlı okuma yapılıyor. Spritz hakkında bolca övgü de, eleştiri de mevcut.

How to fix the installation problem of the module "pg" for Node in Mac OS X Problem
When you issue npm install pg command to instal pg package for Node on your Mac OS X, you might get an error like this "...error: The program ['pg_config'] is required" Error simply implies that pg installation cannot find pg_config file. Solution 1. First make sure you installed PostgreSQL. 2. Find the path to your pg_config file. In my case it is /Library/PostreSQL/8.4/bin/pg_config 3. Open the Terminal and enter the following commands one by one PG_CONFIG=/Library/PostreSQL/8.4/bin/pg_config export PG_CONFIG npm install pg Syncing your iPhone contacts might get ugly if you do not know how to do it or you use an app that is not well tailored for your needs. In this tutorial I'm going to show you how to sync your Gmail contacts (with groups) with your iPhone. Let's get started. First, you need to backup your contacts from your Gamil account. To do that, go to Contacts and hit More tab and you will see a dropdown list. Choose Export and export your contacts as Google CSV format. If everything goes wrong you can bring all your contacts back from this backup. Besides you can save this file to your backup drive for another use. After backing up your contacts go to Settings/ Mail,Contacts, Calender on your iPhone and delete all the mail accounts before synchronization. You need to do it since synchronizing works best this way. Othervise you will end up with duplicate contacts or other unwanted behavior. Next step is to install the required app. It is called Contacts EXtreme by POPo's Innovation Ltd. It was a free app when I installed it. When the installation is complete run Contacts EXtreme, hit More tab, scroll down and choose Clear iPhone Contacts. Later, choose Clear Local Sync Data (probably you don't need to do this if this is your first use; however, clearing local sync data won't give any damage). As a final step scroll up and choose Sync with Gmail Contacts. That's it. All these steps worked for me. If they do not work you please leave a comment and I'll try to help you.
If you are using a login form in your .Net Windows Forms application you might want to show a progress bar to the user during authentication takes a little time. Doing that makes your application responsive and makes the users think your application is doing some work and not stuck. You choose the Style property of the progress bar as "Marquee" since you do not know how long authentication will take (possibly not more than 1 or 2 seconds but sometimes servers may respond a little longer than that). By creating the progress bar control with the Marquee style, you can animate it in a way that shows activity but does not indicate what proportion of the task is complete. The highlighted part of the progress bar moves repeatedly along the length of the bar. You can start and stop the animation, and control its speed. In this example when the user enters the user name / password and hits the "Go" button, the lengthy operation is emulated by Thread.Sleep(3000) call. All the labels, textboxes and the submit button are disabled when the highlight of the progress bar moves for 3 seconds. After it finishes moving the controls are enabled again and progress bar is hidden by Hide() method of itself. This gives the cue to the users that they cannot change their input during the authentication process. Download the code (Visual Studio project)![]()

Sometimes you need to keep sensitive information in a Windows Forms application settings file. The settings file is plain text by default. In this case, you'd better encrypt this sensitive information, like a password, to protect from someone capturing the file (user.config, app.config depending on your choice) and seeing the content of the settings file and trying to abuse it. Encrypting settings is very easy. Al you need is:

In other words, the // "Password" is null or empty. try { // Crypto is the utiliy class that holds the encryption logic // You can use your own encryption utility class for more control return Crypto.DecryptStringAES(((string)this["Password"]), SharedSecret); } catch (FormatException) { // simply return nothing in case of exception return ((string)this["Password"]); } } set { // When you save the settings, the password will be encrypted this["Password"] = Crypto.EncryptStringAES(value, SharedSecret); } } } } An encryption utility classusing System; using System.IO; using System.Security.Cryptography; using System.Text; namespace EncryptingWindowsFormsSettings { // Encrypt/Decrypt string in .NET // http://stackoverflow.com/questions/202011/encrypt-decrypt-string-in-net public static class Crypto { private static readonly byte[] Salt = Encoding.ASCII.GetBytes("dE4ffrTy7/!"); /// <summary> /// Encrypt the given string using AES.
