[Grails] Use Domain.withNewSession instead of refresh()

Waaaaaaay faster.
For instance, if you have a service run by a scheduled recurring Quartz job, the service seem to be attached to a thread which does not see the updated fields in the database (always returns cached values). We may refresh the whole domain calling the refresh() method on the domain class instance, or just do this:

def allCampaigns
        Campaign.withNewSession{ session ->
            allCampaigns = Campaign.findAll("from Campaign where myStatus IN ('active','paused') OR myStatus = null")
        }

Cleaning up /boot

dpkg --get-selections|grep 'linux-image*'|awk '{print $1}'|egrep -v "linux-image-$(uname -r)|linux-image-generic" |while read n;do apt-get -y remove $n;done

Such a great naming convention

Well done, Oracle. Go Groovy!

I just wanted to download the JDK and look what welcomes you at the Oracle website:

ByteArrayOutputStream.toString() human readable

I can do this for a readable output:

public class Changer {
    public static void main(String[] args) {
        try {
        java.io.InputStream in = new java.io.FileInputStream(new java.io.File("DBSDashboard.XML"));
        java.io.OutputStream out = new java.io.ByteArrayOutputStream();
        org.jdom2.input.SAXBuilder builder = new org.jdom2.input.SAXBuilder();
        org.jdom2.Document document = (org.jdom2.Document) builder.build(in);
        org.jdom2.Element rootNode = document.getRootElement();
        org.jdom2.Element ccc= rootNode.getChild("CallCentreClosed").getChild("callCentreClosed");
        ccc.setText("true");
        /* or, ccc.setText("false") */
        org.jdom2.output.XMLOutputter xmlOutputter = new org.jdom2.output.XMLOutputter();
        xmlOutputter.setFormat(org.jdom2.output.Format.getPrettyFormat());
        xmlOutputter.output(document, out);
        System.out.println(out);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

And voila:

 
    false

Good to know.

MKP, y u no have English?!

Az előbb - unalomból - megnéztem az MKP hivatalos honlapjának angol nyelvű verzióját. A jobb felső sarokban: random kép. Csáky-Bugár dwa bratanki, azaz két jó szivar. Pártszakadás volt? Ezek szerint nem. So keep smiling.

Ubuntu open router

ip_forwarding = 1
sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

... think about your network design before you start kicking your head against the wall.
Poor external router does not know anything about internal addresses.
