Techempower Framework Benchmark 10 Preview 6

New framework benchmark preview has been published, still C++ on top, JavaScript second, followed by Scala, Nimrod, Dart and Go. There are no quite significant changes with previous benchmark.

But as I stated before, performance is not everything. It won't be really good if the writing/compiling/debugging process took too much time.


Techempower Framework Benchmark 10 Preview 5

New framework benchmark preview has been published, still C++ on top, JavaScript second, followed by Scala, Nimrod, Dart and Go. HHVM no longer on top because of some technical error. I think other benchmark seems not realistic enough '___')

But as I stated before, performance is not everything. It won't be really good if the compiling/debugging process took too much time.


Manga Downloader on Linux

There are plenty of options to automate manga download on Linux, for example: AnyMangaDownloaderBatotoDownloader, LinuxMangaDownloader, HakuNeko, MangaTux, MangaEdenBatchDownloader, MangaDownloader (command line), MangaCrazy (jar), and Zenbu. And of course you can look for another alternatives on github.

MangaTux required you to give the URL manually (you cannot search within the program), it support some Spanish and English manga site (MangaHead, MangaFox, MangaShare, MangaReader, Animea) even 4chan, zerochan, danboru and pown.it. On ArchLinux, you can install and run using this command:

yaourt --needed --noconfirm -S --force mangatux

With Hakuneko you can search within MangaReader, MangaHereMangaFox, Batoto, and KissAnime (doesn't work). The interface are quite straightforward. You can install and run using this command:

yaourt --needed --noconfirm -S --force hakuneko

MangaEdenBatchDownloader also similar to MangaTux. You can install and run using this command:

yaourt --needed --noconfirm -S --force mangaedenbatchdownloader
java -jar /opt/edenbatchdownloader/EdenBatchDownloader.jar

BatotoDownloader exactly similar to MangaEdenBatchDownloader, You can install and run using this command:

yaourt --needed --noconfirm -S --force batotodownloader
java -jar /opt/batotodownloader/Batoto.jar

To read manga (cbz, cbr, cbt, cba, cb7rar, zip, tar, ace, 7z, etc) you can use MComix, the install and run command:

yaourt --needed --noconfirm -S --force mcomix

I think the best one for now is Hakuneko.


Monitorix: System Resource Monitoring for Linux

Monitorix is a daemon that enables you to monitor your Linux server/system resources. It has built-in web server, and developed using Perl. To install the daemon on ArchLinux, use this command:

yaourt --needed --noconfirm -S --force monitorix
sudo systemctl enable monitorix
sudo systemctl start monitorix

The configuration file can be found on /etc/monitorix/monitorix.conf, for example you can enable the built-in webserver and change the port, change the network interface's to be monitored or enable and disable sensors, just find the key and change it, for example:

  enabled = y
  host =
  port = 8081
  user = nobody
  group = nobody
  log_file = /var/log/monitorix-httpd
  hosts_deny =
  hosts_allow =
    enabled = y
    msg = Monitorix: Restricted access
    htpasswd = /var/lib/monitorix/htpasswd

  system  = y
  proc    = y
  fs  = y
  net  = y
  user  = y
  netstat = y

  list = enp2s0, wlp3s0
  enp2s0 = Gigabit LAN, 0, 10000000000
  wlp3s0 = Wireless LAN, 0, 100000000
  gateway = enp2s0

After changing the configuration file, you  may want to create a password so no other user can see the web, for example to create a new user named test with password youMayNotKnow:

sudo htpasswd -bcd /var/lib/monitorix/htpasswd test youMayNotKnow

after that, don't forget to restart the service:

sudo systemctl restart monitorix

Then you can see the result by visiting


Prime Number Generator Benchmark

Today we're gonna benchmark about prime number generator (without sieve and prime library). The spec is generating all prime number below 10 million and outputting every 100k-th prime found. As usual, the source can be found on my dropbox (folder: prime). The benchmark performed on 64-bit Linux, i3-4150, 16GB RAM and non-SSD disk.

Note #1: PH7 failed to give any output within 1 minute.
Note #2: IO failed to give complete output within 2 minutes.
Note #3: Nimrod caches the compile process, so the second time compile are less than 100ms
Note #4: Potion failed to give complete output within 2 minutes.
Note #5: Gnatmake caches the compile process, so the second time compile are less than 10ms, but it doesn't overwrite when different flag used (-O2 for example).
Note #6: Some languages can be compiled, and some other can be executed directly using certain command, but I choose one that I learned first (but I will benchmark both method when I have much free time)
Note #7: Compile cache deleted before every (3) benchmark run, the value taken are the median.
