57th Monthly Technical Session (MTS) Report
Monthly Technical Session (MTS) is HENNGE’s mini-conference. As the name implies, MTS is held monthly and the talks are (mostly) about technology.
The 53rd MTS was held on April 19th, 2019.
“Dad Takes Child-care Leave” by Arakawa
He has talked about his experience of 6 months paternity leave.
Before entering it, he thought that he will have a lot of free time. But, he didn’t have any free time for extra activities during his paternity leave.
Through his experience, he realized that all most all of mothers who take care of their children are in the same situation. To save his time, he bought better housekeeping tools and used Google calendar to manage a lot of tasks. Also, he used “パパっと育児” app for recording his baby’s activities and visualizing them. He could predict how much milk does his baby want.
Using better tools makes your child care efficiently and you will have your free time. Also, it is the most important thing, do not worry too much about your child care. No one has perfect child care practices. Enjoy your life with your new family.
“AWS IAM Permissions Boundary” by Bagus
In our DevOps team, they often change IAM permission. At such time, he changed it by his hand. It is not a good way. So he uses Permission Boundary to change this situation.
Permission Boundary is one of the ways to restrict IAM permissions. IAM who has Identity-based permissions and Permission Boundary can perform an action only which is included common both of permissions. Now he uses Permission Boundary to IAM roles for terraform.
“FIDO2 + WebAuthn” by Tanabe
He introduced FIDO, FIDO2, and WebAuthn this time.
FIDO is one of the authentication technologies that aims for the passwordless world. Leaking passwords is the most terrible incident of web security. FIDO will reduce the incident.
FIDO2 is a project to bring FIDO to the web. A part of FIDO2 is submitted to W3C and it is proposed as WebAuthn.
Nowadays, major browsers like Chrome, Firefox, and Edge support WebAuthn. So you can try passwordless authentication with your browser.
“Interpretable Machine Learning” by Iskandar
Machine learning is used widely to get better predictions, to find unknown relationships or law. Nowadays, there are some cases that machines can detect lesions from X-ray images better than human. On the other hand, we can’t explain how do they decide it. To understand why they decide so, interpretability of machine learning is getting important.
This time, he introduced Interpretable Models and Model-agnostic Methods. Interpretable Models is the way how to build interpretable models from your dataset. Model-agnostic Methods is to get explanations of why we got a result. Also, he explained that LIME is one of the Model-agnostic Methods using his machine learning project.

“Quantum Computing. Post-Quantum Cryptography” By Alex
He told about the basis of quantum computing and the concept of Post-Quantum cryptography.
Current cryptography is based on the difficulty of calculation. For example, RSA that is widely used for secure data transmission is based on the difficulty of factoring of the number that is generated from two large prime numbers. Getting the numbers from the composite number is taking a lot of time. But, if Quantum computer has been implemented, this situation will be changed. Because Quantum computer can calculate in parallel. Also, algorithms for decoding coded messages that are encrypted with current cryptography are being developed.
Now, scientists are developing Post-Quantum cryptography. On this presentation, he introduced Lattice-based cryptography.
“A Brief History of The Greatest Conqueror of All: Money” by Yuri
She introduced 3 “Universal Order” from “sapiens” that is one of the international bestsellers.
According to the book, there are 3 universal orders. Religious, Political and Economical order.
This time, she talked about Economical order, history of money.
Before developing money, people share goods or exchange their products. But, it is complicated to track the currency. So people have developed money to make trade easy.
People can trade systematically with money. Money works based on trust. And money is easy to store compared with agricultural products that are used as currency before developing Money.
Nowadays, we can trade goods regardless of the difference of religion, culture or language.
As usual, we had a party afterward :)
