It's a little bit confusing changing the font size of IDE controls and menus. The options dialog has only font size changes for the editor, not for the whole IDE. This is specially helpful on windows with scaled screen resolution on HiDPI displays.

The trick is to add an additional parameter to the VM options in the netbeans.conf configuration file. On Windows this is e.g. C:\Program Files\NetBeans 8.2\etc\netbeans.conf, on OS X /Applications/NetBeans/Netbeans 8.2.app/Contents/Resources/etc.

Add the parameter --font-size to the line starting with netbeans_default_options.

Example:

 netbeans_default_options="--font-size=14 -J-client -J-Xss2m -J-Xms32m"

Now the IDE has a font size of 14pt for the IDE.

After last update of OS X  El Capitan to version 10.11.2 the finder open dialog lost the favorite section in all applications. The finder itself displays it further.

To solve this problem you must delete the file

~/Library/Preferences/com.apple.finder.plist

and restart finder with killall -KILL finder or restart the system.

The bash shell for windows is a good extension to use git unter windows. But if you use ssh-based connections it is frustating to enter the passphrase for each connection.

Activating the ssh-agent solve this problem. Create the file .profile in your bash home directory and after starting the bash shell it also starts the ssh-agent and asks once for your ssh passphrase. The passphrase is cached in the ssh-agent during your bash session.

#!bash.exe
export SSH_AUTH_SOCK=/tmp/.ssh-socket
echo ;
echo Starting connection with ssh-agent...
ssh-add -l 2>&1 >/dev/null
if [ $? = 2 ]; then
  rm -f /tmp/.ssh-script /tmp/.ssh-agent-pid /tmp/.ssh-socket
  # Exit status 2 means couldn't connect to ssh-agent; start one now
  echo Creating new ssh-agent...
  ssh-agent -a $SSH_AUTH_SOCK > /tmp/.ssh-script
  . /tmp/.ssh-script
  echo $SSH_AGENT_PID > /tmp/.ssh-agent-pid
  ssh-add;
  echo ssh-agent set up successfully.
  ssh-add -l
fi

It's a little difficult to find the rescue mode in Ubuntu 11.10. Since 11.04 you can press the shift key in startup phase to show up the grub boot menu.

First step is changing the following line in /etc/default/grub

<br />
GRUB_HIDDEN_TIMEOUT=0<br />
 

to

<br />
GRUB_HIDDEN_TIMEOUT=1<br />
 

Activate the changes by running /usr/sbin/upgrade-grub.

Now you can boot up your system and can press the shift key to access the grub menu.

Another important thing is that the file systems are mounted read-only in rescue mode. If you want make changes to the file systems then you must first choose the remount option in the boot menu.

An IBAN may contain up to 34 alphanumeric characters and is composed of the following parts:

• Double-digit alphabetic code according to ISO3166
• Two-digit numeric check digit over the whole IBAN under Modulo 97-10 (ISO7064)
• Maximum 30-digit Basic Bank Account Number (BBAN), consisting of the Institute identification (IID) and Bank Account Number (BAN)

The IBAN in electronic form contains no spaces, but  in a printed form it is usually presented into groups of four characters with spaces . The last group of characters contains the remaining characters of the IBAN. In this way the IBAN is easier to read. By validating the check digit in the IBAN the frequent cross-border payments misdirections can virtually ruled out. The Basic Bank Account Number is used by the financial institutions identified in the respective countries and the customer account at a bank. The IBAN can be derived, although usually from the domestic bank account number, but it is not always reliable. Therefore the European Committee for Banking Standards (ECBS) has indicated that an IBAN should in principle only be made by the account-holding financial institution. The software-calculation of the IBAN bank account number and ID is not recommended and may lead to incorrect results. A check of the check digit is useful to prevent input errors.

Check digit for IBAN

For the IBAN check digit calculation method, the modulus is used 97-10 (ISO7064). The purely numerical check digit consists of two bodies and is for all participating countries are following the country code at position 3 and 4. In order to calculate and validate the check digit, the alpha characters of the IBAN must be converted using the conversion table below, in double-figures.

Swiss Interbank Clearing AG has described an example of the check digit for IBAN. The starting point is the IBAN CH10002300A1023502601. The presentation in paper form would be: CH10 0023 00A1 0235 0260 1. Thus, the check digit is 10. First, the first four characters of the IBAN must be moved to the right end of the IBAN: 002300A1023502601CH10. Subsequently, the alpha characters are converted using the conversion table in numeric characters: 002300101023502601121710. This number is divided by 97. If the check digit is correct, the residual value is always 1.
