Whatsapp online tracking

Posted on 05.07.2020 by Elhana

Simple devtools script to track when User is coming online/offline with privacy options on (whatsapp is not showing last seen)

function getElementByXpath(path) {
   return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue;
 }
 var online = false;
 setInterval(function() {
  if (getElementByXpath('//*[@id="main"]/header/div[2]/div[1]/div/span').textContent == "User to track") {   var lastSeen = getElementByXpath('//*[@id="main"]/header/div[2]/div[2]/span');
   if (lastSeen != null) {
     var today = new Date();
     var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
     var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
       console.log(date + " "+ time + ", " + lastSeen.textContent);
     if (online == false) {
         new Notification(date + " "+ time + ", " + lastSeen.textContent);
         online = true;
     }
   } else {
      if (online == true) {
         var today = new Date();
         var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
         var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
         new Notification(date + " "+ time + " Offline");
         online = false;
     }
   }
  }
 }, 1000);

Set network.proxy.autoconfig_url to a proxy.pac url

Set network.proxy.type = 2

mysql upgrade error – start failed

Posted on 11.12.2012 by Elhana

Was upgrading today and got this:

Setting up mysql-server-5.5 (5.5.28-0ubuntu0.12.10.1) ...
start: Job failed to start
invoke-rc.d: initscript mysql, action "start" failed.
dpkg: error processing mysql-server-5.5 (--configure):
 subprocess installed post-installation script returned error exit status 1

yay, so it can’t start for some reason..
#tail -n 20 /var/log/mysql/error.log:

Google says aio on tmpfs doesn’t work. I don’t want mysql to store it’s crap on my disk – it is just my desktop db and I don’t need it to be blazing fast and contribute to ssd wear.

Solution in my case is innodb_use_native_aio = 0 in my.cnf

zip individual files recursively

Posted on 26.01.2011 by Elhana

Zip up every fb2 file in a book collection to save some space since reader can read them from zip files anyway:

find . -type f -execdir zip -m '{}'.zip '{}' \;

Range check 3.3.5 Proof of concept code – AVR style.

Posted on 05.07.2010 by Elhana

eRange_PoC

– Range setting taken from DBM /range – need to set it first.
– Friendly nameplates and overlapping nameplates has to be enabled for this to work, however there is a code that tries to hide everything, but name.

For those who will QQ that blizz will now break something else because of this – I believe that having an opportunity for the addon to exist only means that someone will eventually use it and keep it private to gain advantage over those who can’t make their own version, therefore releasing this to keep the balance of the force.

Everyone is free to to improve it and add some boss mods.

I’d be happy if someone would just write functions to determine Camera position from 2+ friendly nameplates on screen and make AVR work again.
I realized I don’t remember math that well anymore and it might take me few days to get back on track with those matrix transformations >:(

p.s. Code is a quick hack, so it is probably messy. There is no OnUpdate throttling – it doesn’t seem to affect my fps even in raids, cba.

Looks like MS deployed some patch today (KB971033 it seems) that fixed windows activation with loader. This gets you back in action:
