Does #Bitcoin use too much energy? Is it bad for the environment? What happens to mining when the price of #BTC changes? When hardware changes? All you ever wanted to know about the dynamics of #Bitcoin mining but never dared ask: arxiv.org/abs/2201.06072

"Ce que l'on conçoit bien s'énonce clairement" - Boileau
The most important component of writing clearly is simply to have high standards for clarity. Then if you write something unclear, you notice, and ask: what did I mean to say? You can just keep doing this over and over. And if you have high standards for clarity, you will.

hot take: OpenAI wants the government to force every citizen to buy their stock.
OpenAI has written a new policy proposal 'Industrial Policy for the Intelligence Age: Ideas to Keep People First.' They propose the creation of a Public Wealth Fund that will provide American citizens with an automatic public stake in AI companies and AI infrastructure even if they are not invested in the market. Returns from the fund would be distributed directly to citizens.

Preach @DSBatten !
We now have official EEP data that shows Bitcoin mining has nearly doubled Ethiopia’s annual net transmission grid expansion rate Even more importantly, it has catalyzed an unprecedented level of new construction activity never before reported by EEP at this scale. Consider this context: Delivery of power to rural Africa, alongside combatting youth unemployment is one of the two biggest political changes in sub-Saharan Africa. Bitcoin mining has just demonstrated it can be a viable solution for one of them Let's dig in. Ethiopia made $220 million from Bitcoin mining in 2024/25 which is expecting to increase to $312 million this year (source: capitalethiopia.com/2025/11/… This electricity would otherwise have been wasted Why? Although Ethiopia has the capacity to generate 6 Gigawatts from the new dam, Ethiopian Electric Power (EEP) hasn't yet built the transmission lines to supply all that electricity generated. So, in the meantime the dam authorities sell electricity to Bitcoin mining companies. These electricity sales to Bitcoin miners were 67% of EEP's total Foreign Exchange revenue last year, vastly improving profitability. source: birrmetrics.com/ethiopia-ele… What do they do with that unexpected extra profit? EEP has stated repeatedly that the revenue from Bitcoin mining is used to support "infrastructure expansion" and "rural electrification" source: eep.com.et/?article=ethiopia… News channel Aljazeera recently confirmed "Ethiopia doesn't yet have the distribution network to take electricity to 1/2 the population...The idea is the fees paid by the Bitcoin miners will go towards funding the expansion of the grid." source: youtube.com/watch?v=mqie7bWQ… Significantly, EEP's own data shows revenue from Bitcoin mining supported EEP's 2024/25 fiscal year * 28,571 km new power lines built * 8,700 substation bays installed Source: birrmetrics.com/ethiopia-ele… Bitcoin mining revenue has already almost doubled EEP's rate of energized network buildout from ~358 km/year average to 662 km last year. But more important is what is in the imminent pipeline: the 28,571 km of new power lines is larger than the entire size of their grid! source: eep.com.et/wp-content/upload… Let's be clear, we cannot say that "Ethiopia build more than their whole grid in a year" because not all of that new capacity has been fully energized yet, so that would be an apples-for-oranges comparison. But it is still an unprecedented rate of new construction. The good news is that the bulk of this infrastructure constructed but not yet fully energized is not “waiting years”, it is in active commissioning right now and is expected to come online progressively over the next 12–18 months. Source: Birr Metrics (EEP’s 2025/26 budget announcement) birrmetrics.com/electric-pow… When that new network is fully energized, the increase in the speed of energized network buildout will not be 2x. It will be substantially higher, potentially more than 10-20x the historical average as the backlog comes online. Read that last sentence again. A forecast 10-20x faster buildout of Ethiopia's electrical grid. Rural electrification of Sub-Saharan Africa is a key strategic focus for over 20 global institutions and development banks, including the UN, World Bank, IRENA, African Development Bank, and Rockefeller Foundation. It is even explicitly one of the UN’s Sustainable Development Goals (SDG 7), where Target 7.1 calls for “universal access to affordable, reliable, and modern energy services by 2030.” Sub-Saharan Africa accounts for 85% of the world’s people still without electricity (mostly in rural areas), making this one of the biggest global priorities. How Ethiopia is achieving this should be one of the biggest stories at the UN right now. Far from “taking renewable power away” from people, Bitcoin mining’s use of otherwise wasted renewable energy is catalyzing the accelerated delivery of electricity to rural Africa. Bitcoin mining has created a pragmatic solution to an issue that has plagued powerful global institutions for decades. If you are still gaslighting Bitcoin mining in 2026 (based on early studies, now been widely debunked), you are no longer just uninformed. You are perpetuating harmful myths that slows down power delivery to people living without electricity.

antidisestablishmentarianism !
As a Bishop, I cannot stay silent. I have today drafted and sent an open letter to His Majesty King Charles III, the text of which reads as follows: To: His Majesty, Charles III, King of the United Kingdom and the Realms, Supreme Governor of the Church of England, Bearer of the ancient title Defender of the Faith. Your Majesty, I write to you neither as a politician nor as a commentator, but as one of your loyal subjects who, as a bishop of Christ’s Church, cannot remain silent while the Christian foundations of this kingdom are steadily dismantled. Sir, there are moments in the life of a nation when silence becomes a form of betrayal. If I refused to speak to Your Majesty now, this would be such a moment. For more than a thousand years the Crown of this realm has stood in solemn covenant with the Christian faith. The laws of this land were shaped by it. The liberties of our people were nurtured by it. The conscience of our civilisation was formed by it. From the abbeys of medieval England to the parish churches of our villages, from the preaching of the Reformers to the missionary zeal that carried the Gospel to the ends of the earth, the Christian faith has not merely influenced Britain — it has defined her. Yet today that inheritance is being quietly but deliberately eroded. Across the institutions of this nation there is a growing hostility toward the faith that built them. Christian belief is mocked in the public square. Christian morality is dismissed as intolerance. Christian institutions are pressured to surrender doctrine in order to conform to the ideology of the age. Within the very Church that bears the name of England, voices have arisen that appear more eager to mirror the spirit of the age than to proclaim the eternal truth of the Gospel. Meanwhile, beyond the walls of our churches, powerful political movements openly speak of removing Christianity from its historic place within the life of this nation. What would once have been whispered is now proclaimed openly: that Britain must become a post-Christian state. It is in this context that I write to you, Your Majesty. For the British Crown does not stand apart from this crisis. The Sovereign of this realm bears a title that is not merely historic but sacred in its origin and meaning: Defender of the Faith. Those words are not decorative. They are a charge. They speak of a monarch whose duty is not merely to preside over the ceremonies of the Church, but to stand as a guardian of the Christian inheritance of the nation. Yet many among your subjects now ask, with increasing anxiety: “Who will defend that inheritance today?” They see a nation drifting from its foundations. And they ask whether the Crown will remain silent while that inheritance is dismantled. Your Majesty, may I be so bold as to observe that your coronation oath was not a poetic formality. It was a solemn vow made before Almighty God to maintain and preserve the Protestant Reformed Religion established by law. Those words bind the conscience of the sovereign. They remind the Crown that its authority is not merely constitutional but moral. The monarch is not merely a symbol of national continuity, but a custodian of the spiritual inheritance that shaped this realm. History records moments when kings and emperors were confronted by the Church and reminded that their authority was accountable before God. In the fourth century Ambrose of Milan stood before the Emperor Theodosius I and reminded him that even the ruler of an empire must bow before the moral law of Christ. That tradition of prophetic witness has never disappeared. Nor should it. For when rulers forget the foundations upon which their authority rests, the Church must speak — not with hostility, but with holy clarity. And so, I write to say this, Your Majesty: The Christian character of this nation is under profound and accelerating assault. If the Crown does not stand visibly and courageously in defence of that inheritance, history will record that the guardians of Britain’s institutions watched in silence as the foundations were removed. The issue before us is not nostalgia. It is civilisation. Remove Christianity from the story of Britain and you do not create a neutral society — you create a moral vacuum. And history teaches us that moral vacuums are never left empty for long. Your Majesty now stands at a crossroads that few monarchs in modern history have faced. For the erosion of Britain’s Christian inheritance will not ultimately be judged by speeches made in Parliament or debates in the press. It will be judged by whether those entrusted with the guardianship of our ancient institutions chose to defend them — or merely preside over their quiet surrender. You may preside over the quiet dissolution of Britain’s Christian identity. Or you may rise to the ancient responsibility entrusted to the Crown and speak with clarity about the faith that built this kingdom. The first path requires little courage. The second will require a great deal. But it is the path that history honours. Your Majesty’s subjects are not asking for religious coercion. They are asking for leadership. They are asking that the sovereign who bears the title Defender of the Faith remember what that title means. They are asking that the Crown hear the growing cry of anguish from Christians across this land who feel that the spiritual inheritance of their nation is being surrendered without resistance. And they are asking whether the Crown will stand with them. For the faith that shaped Britain is not merely a cultural ornament. It is the wellspring from which our laws, our liberties, and our moral imagination have flowed. If it is cast aside, the nation will discover — too late — that it has severed itself from the very roots that sustained it. Your Majesty, to many the Crown is a symbol of authority. But before God it is also a symbol of stewardship. And stewardship carries with it the duty to defend what has been entrusted. May Almighty God grant Your Majesty the wisdom to discern this hour, and the courage to fulfil the sacred duty entrusted to the Crown. Yours faithfully, Bishop Ceirion H.

LLMs are (imperfectly) preserving the knowledge we are losing as websites die off. Lately I've come to think of LLMs as the most important readers of blogs. Posts are speaking, not into the void, but into a tunnel to the future.

Good thread on weights as compression and inference as decompression here👇 x.com/i/status/2032853995790… LLMs are currently not very good at compression during inference. Eg ability to generate great jokes, proverbs, aphorisms, elegant (not just correct) mathematical proofs, ...

I think one of the conclusions we should draw from the tremendous success of LLMs is how much of human knowledge and society exists at very low levels of Kolmogorov complexity. We are entering an era where the minimal representation of a human cultural artifact... (1/12)
