Mencoba scikit-learn terbaru

Python di komputer saya diinstall dengan  Anaconda 4.3.1, dengan versi Python 3.6. Namun scikit-learn bawaaannya masih versi lama, jadi mesti install dulu scikit-learn terbaru. Lumayan juga mesti download sebanyak 151 MB.

Momentum untuk algoritma

Tulisan dengan ilustrasi menarik  tentang momentum, khususnya pada machine learning.

Pesawat Tempur F-35 dan Internet Explorer

Apa kaitan antara pesawat tempur F-35 dan Internet Explorer?

Pesawat tempur F-35 yang dimaksud adalah yang ini:

Internet Explorer yang dimaksud adalah browser Internet Explorer di Windows:

Menurut situs warisboring, Internet Explorer dipakai untuk login ke perangkat lunak ALIS (Autonomic Logistics Information System)  yang dipakai untuk menjalankan pesawat F-35 tersebut.

It took several days for the crews to get ALIS working on the local base network. After extensive troubleshooting, IT personnel figured out they had to change several settings on Internet Explorer so ALIS users could log into the system. This included lowering security settings, which DOT&E noted with commendable understatement was “an action that may not be compatible with required cybersecurity and network protection standards.”

Yang menarik adalah bahwa software Internet Explorer tersebut harus dijalankan dengan setting keamanan yang lebih rendah dari seharusnya.
