    From the blog post:

    Since our talk, every few months, I’ve gotten the urge to write a blogpost about the paper. Among other cool things described in the paper, we…

    • Implemented a powerful machine-learning-assisted side-channel attack that can be pulled off in any modern web browser
    • Demonstrated for the first time in the literature that system interrupts, a low-level mechanism that your operating system uses to interact with hardware devices, can leak information about user activity
    • Learned a valuable lesson about the dangers of applying machine learning toward hardware security research

    I think some of these lessons are widely applicable, even outside of hardware security research.

    We depend on the market and we also depend on regulation, both public and private, to have a chance of making reasonable decisions about most of the products we buy. If it’s anything more complicated than buying fruit at a fruit stand, you can’t tell by looking at it. (Even then, sometimes you’re trusting labels.)

    A vote not cast for us is a vote cast for them (interestingly, the opposite of this is never voiced: "a vote not cast for them is a vote for us.")

    Technically, a vote not cast for them is worth half as much as a vote cast for us, and neither is worth very much.

    More generally, I wish there was a bit less heat about who personally votes. It’s true that it all adds up, but for any given person, the adding-up is mostly other people. In a get-out-the-vote effort, it’s about what happens at scale and we shouldn’t worry about one vote more or less. If someone isn’t interested, you move on.

    In this case we’re talking about hypothetical voting, so it’s especially disconnected from any real consequences.

    I think this bit is partly misleading, though:

    What I'm saying, I guess, is a very simple democratic process. If you want people to vote for you, you have to take them and what they want seriously, and at the very least make concessions to them. If you do not, they probably won't, and you can't blame them

    This is true at scale, where politicians try to appeal to as many people as they can. But at a personal level, this sort of thinking is greatly overestimating your influence, a sort of fantasy about having power when you don’t have any to speak of over events. In most elections, you are only one of millions and can’t expect to have any influence on policies, or at least not through voting alone. It’s not a form of personal expression, not like shopping for something that fits you personally. It’s just pushing the Ouija board a tiny bit - worth doing because it does add up, but not worth worrying about if you don’t manage it for some reason.

    So I think it’s okay to feel good about voting, but with no expectations.

    There is power that comes from being an organized interest group, but to play that game you need to actually organize, and it’s based on how many votes the leader of your group can deliver. Many of us aren’t taking even the first step towards organizing, so we are mostly spectators, talking about politics because it’s interesting. I agree with @NaraVara - we don’t have thr habit of joining things.

    Maybe our talk in social media has a bit of influence, but you’d have to have the numbers of an influencer for it to really make a difference. I prefer to forget about that most of the time and just focus on having a decent conversation for its own sake.

    Israel’s ousted defense minister says the military has done all it can in Gaza (NPR)

    On his last day as Israel’s defense minister, Yoav Gallant told family members of the Israeli hostages in Gaza that the Israeli military had achieved all of its objectives in Gaza and that Prime Minister Benjamin Netanyahu was responsible for holding up a ceasefire deal that would end the war and get the remaining hostages home.

    Netanyahu fired Gallant last week, saying that trust between them had “eroded” and that “significant differences” had emerged between himself and Gallant about how to proceed in the war in Gaza.

    Gallant, who served as defense minister for the entirety of the war until now, told them that there was a deal on the table in July that would have brought the hostages home in two phases – Gallant said he urged Netanyahu to accept the deal but that the prime minister refused.

    Since July, thousands more Palestinians have been killed by the Israeli military in Gaza – bringing the death toll up to more than 43,000 according to the ministry of health – and several more hostages have been confirmed dead as well.

    Dickmann paraphrased Gallant’s words to them: “‘We don't have any more rivals, any more enemies that we can even kill right now, because they're all dead. We killed all of them.’ As the Minister of Defense, he said, ‘I did my job’.” Gallant was referring to a series of high level Hamas leaders who have been killed by the Israeli military, including leader Yahya Sinwar in October.

    Gallant’s firing, according to an Israeli official who spoke on the condition of anonymity to discuss internal deliberations, was announced on the day of the U.S. presidential election because the Biden administration would be otherwise distracted and wouldn’t be able to protest the decision.

    But it didn’t stop the Israeli public from protesting across the country, shutting down major highways, lighting fires and eventually being quelled by police. Many saw this as one more move toward the breakdown of Israel’s democracy.

    From the article:

    The company known for textbook rentals and homework help is running on fumes. Chegg’s stock is down a whopping 99% since its highs in 2021, erasing $14.5 billion in value, and the company has lost half a million paid subscribers. After revenue keeps dropping quarter after quarter, there are doubts it will be able to continue paying its debts.

    The company for years paid thousands of contractors to write answers to questions across every major subject, which is quite a labor intensive process—and there’s no guarantee they will even have the answer to your question. As we know, ChatGPT on the other hand has ingested pretty much the entire internet, and has likely seen any history question you might throw at it.

    Why Is Alameda County’s Vote Count So Slow? Official Blasts Sluggish Pace (KQED)

    That update brought the total number of ballots tallied so far to 238,035, according to the office. Assuming an 80% turnout among Alameda County’s 962,000 registered voters, which would align with recent presidential elections, that would mean the registrar still has a backlog of about 530,000 ballots to process.

    “What we typically see is a slow start, and then we ramp up,” Dupuis said. He said his office’s main challenge is the 460,000 mail-in ballots received on Election Day.

    While Dupuis’ office has gained a reputation for slow and sometimes inefficient operations, Alameda County is not alone in its long, drawn-out vote reporting this election.

    Contra Costa, Marin and Napa counties, for instance, have not reported updated results since their final election night reports. Two other counties, San Mateo and Sonoma, say they’ve processed fewer than 10,000 ballots since election night.

    On the other end of the spectrum, Santa Clara County processed twice the number of votes Alameda County did on election night — 468,395 versus 233,246. Dupuis credited Santa Clara’s performance to having more staff and twice as much high-speed sorting capacity.

    A problem with policy-based messaging is that whether it happens or not is usually up to Congress and the public knows not to trust politicians’ promises, to the point that we often won’t even try to understand the details. One thing that does seem to work is red lines about what you won’t do (“no new taxes”). It’s easier to deliver on not doing anything.

    This cynicism about promises means they’re often not taken literally, they’re just an indicator of what sort of things a politician will do. (For example, everyone believes Trump is anti-immigration and for many people, that’s enough. The specifics are doubtful.)

    Qatar withdraws as mediator between Israel and Hamas, reports say (BBC) …

    Qatar withdraws as mediator between Israel and Hamas, reports say (BBC)

    Anonymous Qatari sources told the AFP and Reuters news agencies that Hamas's political office in Doha "no longer serves its purpose" due to "a refusal to negotiate a deal in good faith".

    Qatar is ready to resume its role as a mediator were Israel and Hamas to show "sincere willingness to return to the negotiating table", the sources reportedly said.

    Hamas have had a base in the Qatari capital since 2012, reportedly at the request of the Obama administration.

    In anonymous briefings to Reuters, US officials said the Qatari government had agreed to tell Hamas to close its political office 10 days ago.

    The call for Hamas to be expelled from Qatar appears to be an attempt by the outgoing Biden administration to force some sort of peace deal before the end of his term in January.

    Were Hamas to be forced to leave Doha, it is unclear where they would base their political office. Key ally Iran would be an option, although the assassination of former leader Ismail Haniyeh in Tehran in July suggests they may be at risk from Israel if based there. It would also not give them anything close to the same diplomatic channels to the West.

    A more likely option would be Turkey. As a Nato member but also a Sunni majority state, it would give the group a base from which to operate in relative safety. Last April President Erdogan hosted then Hamas political chief Ismail Haniyeh and his delegation in Istanbul, where they talked about “what needs to be done to ensure adequate and uninterrupted delivery of humanitarian aid to Gaza, and a fair and lasting peace process in the region".

    The move would also most likely be welcomed by Ankara, which has often sought to position itself as a broker between east and west.

    LLM’s are pattern-matching engines and an easy way to get it to follow a pattern (which is what it wants to do) is to give it a few examples and ask it to continue the list. I wouldn’t say this is user-hostile so much as defying unrealistic expectations that they’re magic. The wide-open UI (ask any question) provides little guidance about what they’re good for, compared to more traditional UI.

    One argument for running LLM’s on your own machine is that you know how much energy you’re using. If it’s running down the battery, you’ll notice. The ones that are practical to run locally don’t use as much energy. They’re also less impressive, but they’re improving.

    You’re right about the gold rush, but we can hope things get better as efficiency improves, people get a better idea of what they’re good for, and available products become more taylored to specific use cases.

    I’m a bit suspicious of how Lakeman can write the history of a country I barely know anything about and make it into such a fascinating story. Nonetheless, on the surface, it seems very well researched. Here is his summary:

    Sometimes while writing these 25,000+ word posts, I feel the need to justify why anyone would want to read about a random country they may or may not have heard of. My pitch for reading about Guyana is that its history involves two death cults, diverse leadership (including individuals of the male, female, black, Indian, white, Chinese, Christian, Hindu, Islamic, and Jewish persuasion), a semi-race war, a legal argument over the definition of the word, “majority,” CIA-backed regime change, a conspiracy to thwart a multi-national territorial arbitration, and the largest per capita oil discovery in the history of mankind.

    Guyana is going to be fascinating to watch over the next decade. One of the poorest countries in the Western Hemisphere is suddenly one of the wealthiest. A political basket case has been handed an impossible bounty and it could produce one of the greatest national economic transformations of the modern era, right up there with Saudi Arabia and Singapore.

    To be honest, I’m not optimistic. I think Saudi Arabia really was an anomaly of competence and the other Arab petrol-states followed suit. I think Guyana has low human capital, deeply entrenched tribalism, and impossible-to-dislodge corruption, so, sadly, the world will probably get another Libya/Angola/Nigeria/Venezuela. But I wish it the best. I hope it can overcome Dutch Disease, the Resource Curse, corruption, nepotism, racism, inefficiency, elite theft, mob pandering, and all the other usual problems that come with great resource wealth.

    Spruce Pine quartz mine restarts production after Helene hits NC mountains (CBS 17)

    Sibelconow says its mine in Spruce Pine is back in operation, announcing that production has restarted and production and shipments are “progressively ramping up to full capacity.”

    The Quartz Corp has not announced when production will restart in the Helene-damaged community, but posted on its website, “Coupled with safety stocks of finished products and those that exist at different levels throughout the supply chain, we do not anticipate any critical situation for our downstream industries in the short or medium term.”

    Does All Semiconductor Manufacturing Depend on Spruce Pine Quartz? (Construction Physics)

    Does All Semiconductor Manufacturing Depend on Spruce Pine Quartz? (Construction Physics)

    Spruce Pine is indeed a key choke point in the modern semiconductor manufacturing landscape, but it’s not quite an irreplaceable, load-bearing column supporting all of the modern economy. It’s closer to occupying a relatively unique niche in a price-performance landscape: there are alternatives, but they’re all some combination of not as good, not as cheap, and not yet developed.

    From the article:

    Taiwan Semiconductor Manufacturing Company has notified Chinese chip design companies that it will suspend production of their most advanced artificial intelligence chips, as Washington continues to impede Beijing’s AI ambitions.

    People familiar with TSMC’s move said its decision was driven by a “combination” of the need to improve internal controls in the wake of that ongoing probe and the next wave of US export controls on chip supplies to China, expected before US President Joe Biden leaves office.

    Do you have other reasons to be looking? I find this a little odd because, while the SF bay area has changed over the years, I don’t think the downsides have much to do with the federal government? Local issues in the current election were things like housing costs, homelessness, and crime. Perhaps new leadership in SF will help a bit?
