Zap them… seriously. Get a battery powered chamber trap. Bait w peanut butter. You will catch minimum 1 every night. Easy to unload and reset. No mess. You’ll know you’ve cleared out the lot of them once you are catching young. The most humane way to deal with an unpleasant situation imo. Good luck!

I created Timechain Calendar to visualize Bitcoin in a new way. Instead of staring at a price chart each day I check my calendar to see how the timechain has progressed since the last time I looked.
The blocks become a new unit of time progression, a much higher-resolution measurement than just a date. Referencing my days and moments with this system connects my experiences to Bitcoin in a profound way.
With the arrival of every new block, the simultaneous generation of new supply and confirmation of user transactions is a very real reminder of the purpose of this network and protocol.
The pace of blocks confirms the continued successful operation of the network. It also reveals the actual impact of changes in the mining difficulty that regulate Bitcoin’s monetary issuance policy.
The halvings unfold in a much longer arc than our standard yearly timeframe. Staying conscious of my progress through the cycles of Bitcoin's fixed-supply enforcement gives greater meaning to the concept.
The visualization of the entire lifetime of the network as a percentage of max supply issued offers a new lens. I can reframe my lifetime in a low time-preference context, which has already yielded very impactful changes in how I live.
I created this tool to encapsulate all of these perspectives in a compact, glanceable interface that functions as my calendar, my daily reference for where and when I am. Simply being aware and staying informed of everything here changes my perception. Checking in and actually seeing the steady functioning of Bitcoin is a comforting and conviction enhancing daily habit.
🙏🧡

New in v0.3.51…
Presenting the Timechain Calendar Gallery!!
A curated collection of #Bitcoin art and literature on the blocks of the app’s interface.
To access the gallery, visit timechaincalendar.com/gallery or simply press the gallery button on the right side of the circles.
From the gallery you can browse the current selection of pieces, each numbered with the block height that each piece was completed on.
Clicking on any piece will take you to the respective block where you will see a thumbnail placeholder of the piece embedded in the UI.
Click the thumbnail to enlarge the piece and find out more details about it.
Click “LEARN MORE” button to find out even more about the artist/author.
The motivation for this feature was simply to bring awareness of some great Bitcoin artists and authors to the users of the app. These individuals use their talents to amplify the ideas that make Bitcoin what it is.
All of the participating individuals agreed to be included in this gallery. More pieces from these folks plus new artists and authors will be added over time.
FAQ: No! The pieces are NOT on chain and this gallery has NOTHING to do with Ordinals or inscriptions.

29637 blocks to halving
At an almost exactly 10 minute avg block time and 69 blocks to go it’s looking like a negligible difficulty adjust coming up in just a matter of hours.
This difficulty epoch will be remembered by me as the great mempool clearing! 👏 https://image.nostr.build/ba0e0df6221c85dfcfe2a27e84afad215a3200ef2449d4d162e2c1799f6c92d3.jpg

300 blocks to the next adjustment. Blocks produced at a brisk pace this period shaping up for a healthy increase in difficulty in about 2 days. https://cdn.nostr.build/i/87d3318b711e3c50f2ca0eff27cc24d9ff143e12fe1452cf7d79c1cbb7fd26ef.png

More than half way to the next difficulty adjust and average blocks now just under the 10 minute target. https://cdn.nostr.build/i/0d26a2bc8e5232dee73fccfb3351b71bdd8b49eee2b4207d997fe0d80393fd45.png

I think it will be a week or so ahead of schedule. We’ll see.

Bitcoin isn’t easy.
A wallet isn’t a wallet. A balance isn’t a balance. A coin isn’t a coin. Mining isn’t mining. 10 minutes isn’t 10 minutes. 21 million isn’t 21 million.

💪Congrats to miners for handling the overflow of block demand! https://nostr.build/i/nostr.build_a0adcd7fa2b72e4be4ae97d6fde6e174b3b26b4ec4d1cb6664d4789abfc31c14.jpeg

The 1 input 1 output txs with larger than “normal” vByte size are all inscription txs. They try to get their “collections” into the same block. A lot dumb shit going on thanks to mining pools like Luxor catering to these NFT morons.

I challenge you to find one intelligent passage in there. His thesis is rubbish.

Image aspect ratio gets squished… try applying height:auto to the image https://nostr.build/i/nostr.build_19be73b4f362319f641038425a6d41d15ee799568dcec37317f77ca4beaa1f41.jpeg
