It’s more than half year my laptop not running Java properly. Since JRE ver 6 and updated to version 7 , Java stop working and have no solution yet. On web, solution offered is uninstall the older version and install new version of java but it’s still didn’t working.

In my case, after installing new version of java, we must verify java version with web browser. On my laptop it’s show blank page even I have allow java plugin to run.

Today I am lucky , I found a reference here , all the problem is on program compatibility … oh my. Just change program compatibility to “Windows NT 4.0 (Service Pack 5)” for javacpl.exe , javaw.exe and jp2launcher.exe , on default java installation folder (C:\Program Files (x86)\Java\jre1.8.0_31\bin on my laptop). After change program compatibility , verify the java using http://java.com/en/download/installed8.jsp , your java must be working properly.

Took 2 weeks for me to decide buy edge 510 , we know the unit too pricey and still not sure about the function for value. The other difficult reason are the bad review, if you googling about garmin edge problem you’ll find ton of complain posting.

Searching other brand like sigma , bryton , wahooo give me other confusion , still no fit with garmin feature. Finnaly , I got garmin edge 510 also with worry inside

When device came , check the firmware , the version shows 2.7 and directly update to 3.2 and start test the device. After several days , here my review for this device :

Connection :
Bluetooth pair with smartphone (Motorola G 4.4.3 Kitkat) not smooth enough , after workout and save the result the device can not connect with smartphone. The solution for now, turn of the device , turn on smartphone bluetoooth then turn on garmin edge. Smartphone and device will connect smoothly

Application :
Came with garmin connect , this device bacome so cool , automatically it sent workout result to strava , trainingpeaks , myfitnespall after I sync the device and smartphone ofcouse you need setup the authentification first with that application

Right now I am very satisfy with this devices, I can do indoor workout or outdoor workout with more fun

Just try old fashion monitoring squid with cacti. Download all XML file required from cacti website and import it using template import on cacti console. All XML import get XML Parse error . The XML file method used is browse XML file from my PC.

There another method and I can’t saw it earlier , just paste the XML code on text area, XML template import just run smoothly :p

This morning I am surprised with 100% CPU usage on my webserver , this is not an usual condition even I know this is high session of web server usage. After checked the server-status of apache I saw so many request to one of my virtualhost, so many POST to xmlrpc.php

First aid , I use my router to do blocking on layer 7 :)) since now it’s still happen , at least web server load became normal

this crazy morning caused by notworking root email forwarding on my local server. it’s always sent email to root@localhost.local domain even I have make root alias on /etc/aliases.

the solotion is’t prety easy , just make .mailrc file on root home directory, so just like /root/.mailrc , on that file fill this one line :

alias root youremail@yourdomain.com


That’s all

Yesterday , my moto g notification tell me about the new update to kitkat 4.4.3 and this morning  it’s time to update. I did online update using setting -> system update. It’s automatically download the update as usual it’s very slow :))

After couple hour waiting, the download was finish then it go automatically reboot to recovery mode , by the way, my phone is rooted and use clock work mod recovery (CWM)  installed. I am not pay attention to the CWM update process , after I am realize something weird happen , the phone didn’t not update successfully :)) , it keep loop on CWM updating script :)) that’s call panic.

I read the CWM update log and find something like :

assert(getprop("ro.product.device") == "falcon_umts" ||
getprop("ro.build.product") == "falcon_umts" ||
getprop("ro.product.device") == "falcon_umts" ||
getprop("ro.build.product") == "falcon_umts");

That’s keep me panic until 11 am , till I know what the problem was , it’s caused by CWM version :)) if you use 6.0.4.6 version , you will get update loop like me :)) , so you just need to update your CWM to 6.0.4.7 ,  you can download it http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.4.7-falcon.img , and flash it using adb . So my phone now officially 4.4.3 :))

Just think how to free the swap without reboot , so it will not hurt the server uptime :p , off course work with OpenBSD server . Here you go.

Use :

#swapctl -l

to know where the swap path

Device 512-blocks Used Avail Capacity Priority
/dev/sd0b 8386576 0 8386576 0% 0

Remove the swap from the kernel, then turn on the swap , again :p

#swapctl -d /dev/sd0b

#swapon -a

And then you can check the swap with “top” command , the swap will be zero :))

This morning I just found something unusual with my cat eye V3N HR sensor, when I put the data to Max it’s show 240 bpm , which it’s very impossible, when I move with bike , the heart rate value on computer keep blinking , it’s seem never happen before.

When I came home I test the HR sensor , I put it beside the computer and I am not wear the HR sensor, on computer it should be display 0 bpm but it was not, it display kind random value and some time max to 240 bpm LoL.

I reset all data , remove HR sensor and computer battery with no result. Just try to googling and found the problem , HR strap was moist  :)) , I washed the HR strap an put it under the sun and  it work again like charm.

Today I need put some WYSWYG text editor for my project, so this first time I use WYSWYG text editor. So far, I user bootstrap modal with textarea only. I decide use ckeditor, the integration with bootstrap quite easy, with minor problem when I wrong put Javascript load syntax  With modal , I use jQuery serialize to POST data from modal to controller, so it was no problem with textarea since I realize there something weird happen.

From loaded textarea data , I change the data on ckeditor but the changes was not POST with serialize function, the POST data is always old loaded data. First I guess  there a problem with modal and ckeditor , after couple hour testing I found there a problem before serialize function .

From this page http://stackoverflow.com/questions/5716644/javascript-and-jquery-serialize-issue I add some function on my script to update the textarea value before it serialize

CKEDITOR.instances.<your textarea id>.updateElement();

Today I just made one of my wordpress site to multiuser , I follow some instruction on internet , so far I think there’s no problem with server configuration , domain and virtualhost. When I add new site, I found it was okay but when I access it it just blank , view source page with no result.

After figure it out, I found that A new site will use “twentyeleven” theme as it default theme , unfortunately I have delete “twentyeleven” theme from my wordpress site :p , so that’s the problem why I got blank site , I point the new site to a new theme available, and everything just work great
