Error: LDAPLocalException: com.novell.ldap.ldif_dsml.LDIFReader: modify record not ends with '-' in the record starting on line 38 of the file. (82) Local Error

Fix:

• go to the line hinted in the error (here: 38)
• get the block of the entry which is modified, for instance:

dn: cn=foo,ou=OUfoos,ou=Groups, dc=DCfoos
changetype: modify
add: uniqueMember 
uniqueMember: cn=myFoo, ou=OUfoos, ou=Groups, dc=DCfoos

• then add a character '-' at the end of this block, you get:

dn: cn=foo,ou=OUfoos,ou=Groups, dc=DCfoos
changetype: modify
add: uniqueMember 
uniqueMember: cn=myFoo, ou=OUfoos, ou=Groups, dc=DCfoos
-

Error:

 LDAPLocalException: com.novell.ldap.ldif_dsml.LDIFReader: Version line must be the first meaningful line(on line 1 of the file) (82) Local Error

 version: 1 

Catastrophe! J’ai efface mon rapport de stage de ma clef USB! Je suis fichu, ma soutenance c’est demain matin a 5h! Mais non, tout n’est pas perdu.

DiskDigger est un logiciel freeware qui permet de recuperer des fichiers effaces, volontairement ou non, sous Windows. En effet, contrairement a Unix, la suppression d’un fichier sous Windows n’efface pas physiquement le fichier de la surface du disque, mais se contente de retirer son adresse logique sur la table de partition.

DiskDigger propose de scanner un disque physique ou logique, NTFS ou FAT, les memoire flash et meme les clefs USB… Tres pratique pour quiconque a deja perdu des photos de vacances lors d’une mauvaise manipulation.

DiskDigger est disponible a ce lien. DiskDigger a ete cree par Dmitry Brant.

Dolphin extends the switch operator to String

Read the rest of this entry »

Tiger (Java 5) introduced new syntax, among which generics are the most used. Mustang (Java 6) did not offer anything new. Dolphin (Java 7) will introduce a new scheme, the “diamond syntax”. We deal of diamond because of the look of theses characters: “<>”

To sum up quickly, in Java 5 we have to write:

[java]
List<Integer>  myList = new ArrayList<Integer>()
Map<String, List<Double>> myMap = new Hashmap<String, List<Double>>();[/java]

On last Dolphin development releases, we can simply write:

[java]
Lis<Integer> myList = new ArrayList<>()
Map<String, List<Double>> myMap = new Hashmap<>();[/java]

There’s nothing revolutionary, but developpers will save a little more time ;-).

Abstract: we need copy all Java files in a folder and its subdirectories.

Solution:

 xcopy C:\<source folder>\*.java C:\<destination folder>\
