@MartyBent Why is there a perfectly Bitaxe sized hole in your display here?

@Rob1Ham Go to a baseball game. They are wild.

Suggestions on what to do in Tokyo?

Thank you @osmu_global for the appreciation of my work and the generous donation! 🤗🥰 Perfectly timed for the (many 🥴) ASICs for the #0xAxe. Everything I learned from the #Flex4Axe, #QAxe, ... went into this. Let's hope it works 🤞Target is 7.2TH/s with 200W and TR4/SP3 cooler

🚨SeedSigner workshop in Raleigh, NC area tomorrow🚨 flockstr.com/event/naddr1qq…

@KeithMukai @SeedSigner @micropython Amazing work, very excited for this

Moar progress! Quirc was updatedw/explicit support for single-precision floats AND keeps the math operations in the single-precision domain (i.e. a BETTER mod than kehribar's). S2: 1873ms ➡️ 1086ms ➡️ 979ms (meh) S3: 1460ms ➡️ 444ms ➡️ 196ms 🔥🔥🔥 @SeedSigner @micropython

@epic_curious @KeithMukai @SeedSigner @micropython I looked at your example and it already had the default frequency set to 240 CONFIG_ESP32_DEFAULT_CPU_FREQ_240=y CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ=240 in sdkconfig

@epic_curious @KeithMukai @SeedSigner @micropython yeah i think i can be done programatically import machine machine.freq() # get the current frequency of the CPU machine.freq(240000000) # set the CPU frequency to 240 MHz

Update! Followed kehribar's lead & converted quirc's double-precision floating point math down to single-precision `float`. Significant speedups for @SeedSigner QR decoding R&D on @micropython! S2: 1873ms ➡️ 1086ms (1.7x) S3: 1460ms ➡️ 444ms (3.3x) github.com/kehribar/esp32…

@skot9000 Today is your day

Dang. I was totally going to consolidate some UTXOs last night and got distracted. Guess I need to put this off some more.

@SGBarbour @james_hilliard @upstreamdatainc Congratulations James and Upstream Data.

Today I am beyond excited to announce that James Hilliard (@james_hilliard) has started work as Chief Technology Officer for Upstream Data (@upstreamdatainc)! James has been involved in the Bitcoin and embedded Linux industries for over 10 years. He is well known in the Bitcoin community for writing the BIP91 specification that activated SegWit (nathanieltnelson.medium.com/the-wildest-ye…), and he continues to contribute his free time to several open source initiatives today. James also has a very wide array of industry experience. He has managed large-scale mining farms, developed mining pool infrastructure, optimized miner production line QA automation, as well as designed various embedded Linux firmware projects such as Bitcoin miner firmware and cryptocurrency ATM firmware. Coinciding with Upstream's business expansion into the US, as CTO James will be responsible for leading our new software initiatives and our overall technology directive. With James' experience and passion on our team, I believe today is a significant milestone for Upstream Data and the bitcoin mining community as a whole. I am honored to have James join me in our mission to develop world leading bitcoin mining infrastructure. James, welcome to Upstream Data! upstreamdata.com/our-team/

@LeoAW @dctrlvan @bitcoin_design Phoenix worked, Cash App scanned it but said "Payment failed", Zeus didn't find anything, Swan didn't find anything, and Mutiny didn't find anything. I'm using a Pixel 5.

I'm making labels for the @dctrlvan vending machine and need help from Android users. Can your favorite #Lightning⚡ wallet scan this inverted QR code (please don't pay it)? cc @bitcoin_design

OSMU member pmaxuw has been making incredible progress on a QUAD BM1366-based open source miner. This thing is seriously rad. If you're interested in more open source #Bitcoin mining radness, you should check out the OSMU Discord; invite link on bitaxe.org

2024 is the year you start mining #Bitcoin at home.

@KeithMukai @skot9000 Oh and it only works with s19k boards at the moment. Probably try for s19j pro boards next as they seem popular.

@KeithMukai @skot9000 Theres a lot to be done. Dynamic frequency and fan adjustments, web server with rest api+web client (can use AxeOs), clean up/refactoring of the gpt converted C code for the BM1366 module. Those are the first things i can think of.

Bitcrane v2, the USB Antminer controlboard is alive! This revision fixes a few bugs in v1 and adds support for 3 hashboards. Run your miner firmware from the comfort of a PC 😎

A decentralized #Bitcoin is a Bitcoin where miners decide what goes in blocks, not pools. OCEAN's ultimate goal is to make this a reality, and today we take one step closer to our vision of decentralized block template construction. Available immediately, OCEAN is offering 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗯𝗹𝗼𝗰𝗸 𝘁𝗲𝗺𝗽𝗹𝗮𝘁𝗲 𝗽𝗼𝗹𝗶𝗰𝗶𝗲𝘀, giving miners control over what blocks they are mining. The three options are: 1) OCEAN Recommended (most real financial transactions and least spam) 2) Bitcoin Core with the “Ordisrespector” spam filter 3) Unmodified Bitcoin Core (same as other pools with fewest financial transactions and most spam) OCEAN will continue its 0% promotional pool fee for options 1 & 2 while there will be a competitive pool fee of 2% for option 3. Our fees are structured to incentivize miners to make choices that benefit the Bitcoin network in the long term. Suggestions for more templates? Let us know at mining@ocean.xyz.

@ck_SNARKs Thank you. This is a huge honor for me and I'm very excited about the potential possibilities of the Bitcoin Core App project.

.@johnny9dev’s efforts to improve the Bitcoin Core App project is also receiving support. Through this work, he hopes to lower technical barriers and make Bitcoin transactions more accessible to a wider audience, starting with users on Android devices.

🎁 @HRF is excited to announce its Q4 round of Bitcoin Development Fund grants. $500,000 to 18 projects across areas such as global education, Bitcoin Core, mining decentralization, and support for devs in Latin America, Africa, and the Middle East.
