Tool to analyze the size of a binary from .elf file

Hi there 👋

I am Jiri, a software developer from Prague.

I am interested in all things about Bitcoin, programming and data-science. My favourite language by far is python (even though Rust starts to come close).

Work projects

I am currently working for Trezor as a firmware developer on the trezor-firmware repository.

For the purposes of firmware repository, I also created two standalone python tools, that we used for decreasing the size of our binary. Both of these are public packages installable by pip:

• binsize - analyzing the size of symbols from .elf files - repository
• upysize - linter to find optimizations to micropython code to reduce its size - repository

Personal projects

When I have time, I like working on hobby personal projects. I have done countless smaller or bigger scripts/applications and each one taught me something new. Some of the most notable are:

• OrdSimilarity - https://ordsimilarity.com/ - a search engine for similar ordinals pictures - repository
• OrdMempool - https://ordmempool.space/ - observing BTC mempool for new ordinals - repository
• BtcStatts - https://btcstatts.com/ - statistics about BTC ordinals - repository
• MusilBlockchain - https://www.musil-blockchain.cz/ - my personal website about blockchain technology from 2018 - repository
• GrdddjDashboard - https://grdddj.eu/ - showing some of the smaller website applications in one directory
• ChessRobot - video - application playing lightning-speed chess on the screen against an opponent - repository
• CalculatorChat - GUI acting both as a calculator and full-featured Messenger-like chat service - repository
• ClipboardMonitor - analyzing clipboard content in real-time and doing arbitrary things with it - repository
• ShortcutsToShortcuts - GUI for binding certain key presses with certain actions repository
• CryptoMarketWatcher - app sending notifications about cryptocurrency prices reaching certain levels - repository
• PiskvorkyInTerminal - my first bigger application, from 2018, when I was starting learning Java and programming in general - repository
