name="type" type="xsd:string" />         </xsd:complextype>     </xsd:element>  </xsd.schema>

to put simply, every part of explaining form of wireless sensor network. need validate system 1 of each of these types, however, after interface removed when try save file.

there several syntax errors in schema. (i able identify them netbeans's "validate xml" functionality, maybe eclipse has too):

  • the closing tag of root element should </xsd:schema> instead of </xsd.schema>

  • several attribute values not enclosed in "s, e.g. in component/behaviour:

    <xsd:element name=send minoccurs="0" maxoccurs="unbounded">

    has replaced with

    <xsd:element name="send" minoccurs="0" maxoccurs="unbounded">

    btw: same subelements of component/behaviour

  • there several attribute values not closed correctly:

    <xsd:element name="from minoccurs=" 1 maxoccurs="1">

    has replaced with

    <xsd:element name="from" minoccurs="1" maxoccurs="1">

of course "fix" functionality can fix errors, cannot fix everything.

ps: tipp: have several "anonymus" complex types, same. can give complex types name too. can extend them. (see http://www.w3schools.com/schema/schema_complex.asp) way reduce amount of code have write.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
