Berkenalan Dengan Apache Superset : Solusi Aplikasi Web Business Intelligence dari Apache

Apache superset ini bisa menjadi pertimbangan sebagai pengganti solusi yang ditawarkan dari software seperti Tableu.

Untuk instalasi, bisa menggunakan docker, atau paling mudah pip. Tapi, terkadang ketika membutuhkan fitur terbaru, seperti menyimpan chart sebagai gambar, kita perlu menginstall dari source. Untuk instalasi source, dapat mengikuti howto yang telah ditulis oleh Kartik Khare [2]

Menambahkan Country Map Indonesia

Baca [3]

ogr2ogr, bisa diganti menggunakan script python berikut :

import geopandas as gpd

file = gpd.read_file("IDN_adm0.shp")
file.to_file("IDN_adm0.json", driver="GeoJSON")

file = gpd.read_file("IDN_adm1.shp")
file.to_file("IDN_adm1.json", driver="GeoJSON")

file = gpd.read_file("IDN_adm2.shp")
file.to_file("IDN_adm2.json", driver="GeoJSON")

File hasil generate geopandas diatas terlalu besar, akhirnya saya menggunakan file [5], kolom yang harus ada pada .geojson adalah ISO, NAME_0 (nama negara) dan NAME_1 (nama propinsi).

Setiap kali melakukan perubahan pada .geojson, superset-frontend harus di build ulang.

Open Data Kit : ODK Scan

Status : Draft

Build

Ketika melakukan kompilasi ODKScanCore, Anda harus menggunakan OpenCV 2.3.1, download disini : https://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.3.1/ (harus melakukan proses kompilasi dari source), ketika melakukan kompilasi, nonaktifkan opsi ffmpeg :

Untuk Mac OS X, penulis menggunakan Mojave, maka sebelumnya perlu menginstall OpenCV 2 dengan perintah :

brew install opencv@2

lalu edit src/Aligner.cpp dan tambahkan baris berikut :

#include <opencv2/nonfree/features2d.hpp>

Lalu untuk Makefile ubah bagian berikut :

INCLUDES := $(OPENCV_INCLUDES)\
-I./jsoncpp-src-0.5.0/include\
-I./src -I./\
-L/usr/lib
-I./zxing/core/src -I./zxing/cli/src

menjadi :

INCLUDES := -I/usr/local/Cellar/opencv\@2/2.4.13.7_3/include/\

-L/usr/local/Cellar/opencv\@2/2.4.13.7_3/lib\

-lopencv_core\

-lopencv_imgproc\

-lopencv_highgui\

-lopencv_ml\

-lopencv_video\

-lopencv_features2d\

-lopencv_calib3d\

-lopencv_objdetect\

-lopencv_contrib\

-lopencv_legacy\

-lopencv_flann\

-lopencv_nonfree\

-liconv\

-I./jsoncpp-src-0.5.0/include\

-I./src -I./\

-lboost_filesystem -lboost_system\

-I./zxing/core/src -I./zxing/cli/src

Solusi :

Here is a workaround solution to fix the issue:

Download MACOSX SDK https://codeload.github.com/phracker/MacOSX-SDKs/zip/MacOSX10.11.sdk
extract head files from MacOSX10.11.sdk/MacOSX10.11.sdk/System/Library/Frameworks/QTKit.framework/Headers/
Create a folder under opencv source file folder: opencv-2.3.1/modules/highgui/src/QTKit, and copy all header files into the folder.

Tangent : Salah Satu Tool untuk Maths Information Retrieval

Status : Draft

Requirement

Tangent menggunakan Pyhton 3, beberapa library yang diperlukan :

Beautiful Soup, pip3 install beautifulsoup4

Instalasi

Untuk instalasi sudah jelas, tinggal jalankan make all. Misal kita setelah mendownload Tangent, menempatkannya di direktori :

/home/wildan/jobstuff/openthinklabs/eksperimen/tangent/tangent.0.3.1

Maka di .bashrc kita perlu menambahkan variabel PYTHONPATH, agar kode tangent bisa kita jalankan :

export PYTHONPATH=/home/wildan/jobstuff/openthinklabs/eksperimen/tangent/tangent.0.3.1/tangent_code:$PYTHONPATH

Jika ketika running masih terjadi error seperti : https://github.com/OpenThink-Labs/Tangent/blob/master/log1.txt

Langkah yang dilakukan untuk mengatasinya adalah :

menguninstall latexml bawaan sistem, dan melakukan kompilasi ulang LaTeXML terbaru, http://software.openthinklabs.com/2017/05/latexml-latex-to-xmlhtmlmathml-converter.html
dan sedikit perbaikan https://github.com/OpenThink-Labs/Tangent/commit/3e7807ae52fa38ca0a523e288432f271b97f2ba4

Seharusnya, jika semua sudah Ok, output python2 index.py akan seperti ini :

Solusi, uninstall kemudian install kembali redis dan hiredis :

sudo -H pip uninstall redis
sudo -H pip uninstall hiredis

sudo -H pip install redis
sudo -H pip install hiredis

Jalankan perintah :

fab setup_deps

Jika muncul error :

Error: Cannot find module 'findup-sync'

indico>>sudo rm node_modules/findup-sync
indico>>sudo npm install -g grunt-cli

Muncul error :

Aborting.

Error ini sepertinya akibat tidak menggunakan phantojs terbaru, setelah menginstall phantomjs terbaru (2.1.1) error ini tidak terjadi.

sudo apt-get remove --purge phantomjs

sudo apt-get install phantomjs

Lalu jalankan :

sudo python setup.py install

Jika ingin setup development environtment untuk indico, bisa menjalankan juga :

sudo python setup.py develop_config

Lalu :

sudo indico_initial_setup

Setelah selesai, akan ada informasi :

Congratulations!
Indico has been installed correctly.

indico.conf: /opt/indico/etc/indico.conf

Please do not forget to start the Celery worker in order to use background tasks
such as event reminders and periodic cleanups. You can run it using this command:
$ indico celery worker -B

If you are running ZODB on this host:
- Review /opt/indico/etc/zodb.conf and /opt/indico/etc/zdctl.conf to make sure everything is ok.
- To start the database run: zdaemon -C /opt/indico/etc/zdctl.conf start

Sesudah mensetup virtual host, dan merestart apache muncul error :
