developmentblockchainJun 7, 2022, 12:51 PM UTCCreating a Solana Wallet mnemonic (seed key) from the CLII explored methods to create a Solana Wallet mnemonic (seed key) from the CLI. While it's possible to generate multiple keys from a mnemonic, for security reasons in case the mnemonic is leaked, it might be safer to divide them into wallets with different mnemonics. Ultimately, I was able to generate mnemonics by running a script, and even obtain public and private keys, making mass production possible.

developmentAug 14, 2020, 10:43 AM UTCI Created a Tool to Calculate Actual Rent Using Rust's wasmI created a tool to calculate actual rent. When entering into a rental agreement, various costs arise in addition to the stated rent. A typical example is key money, and when comparing actual rent, it often differs from what is apparent. Additionally, there are many opaque costs such as insurance fees and mysterious cleaning charges, so this tool provides a function to display these as a unified average rent. This article explains the background of the tool, how to use it, and technical details using Rust's wasm_bindgen.
gameFeb 25, 2020, 2:30 PM UTCThirteen Sentinels: Aegis Rim ReviewThis is a review of Thirteen Sentinels: Aegis Rim. The ADV part has high-quality story, graphics, and sound, with a system that includes action elements. The diversity of characters and the mechanism of switching perspectives are particularly well-done, allowing for smooth progression through the complex story. However, there were fewer surprising elements in the story, and the timing of information disclosure was unsatisfactory in some parts. The tower defense part tends to become repetitive, but overall it's a high-quality work.
