## Highlights >Iran’s [multifaceted approach](https://irregularwarfare.org/articles/exploring-the-cyber-dimension-of-the-current-u-s-iran-crisis/) in the cyber domain allows Iran to project power and influence in the Middle East while avoiding direct conventional military confrontations with stronger adversaries. Iran uses [cyber operations](https://www.recordedfuture.com/leaks-and-revelations-irgc-networks-cyber-companies) to complement its broader geopolitical strategies, often employing cyber espionage and sabotage to gain strategic advantages or to retaliate against sanctions and military threats. As Iran increasingly incorporates AI technologies into its cyber operations, the likelihood of more disruptive and damaging activities escalates, presenting a substantial challenge not only to regional stability but also to global security. >Maj. Gen. Qassem Soleimani’s death marked a [significant turning point in Iran’s cyber strategy](https://ctc.westpoint.edu/cyber-threat-iran-death-soleimani/), pushing Tehran to [assert its power and influence](https://www.recordedfuture.com/leaks-and-revelations-irgc-networks-cyber-companies) through increased cyber activities aimed at the U.S. and its allies >Cyber proxy groups use various tactics to create negative [psychological effects](https://www.microsoft.com/en-us/security/security-insider/intelligence-reports/iran-turning-to-cyber-enabled-influence-operations-for-greater-effect) among adversaries. APTs such as Mint Sandstorm use precise targeting to create unease among a specific group of people. Iran also uses “[faketivists](https://www.darkreading.com/threat-intelligence/iranian-apts-dress-up-as-hacktivists-for-disruption-influence-ops),” which are groups that commit cyberattacks for a specific cause, like hacktivists, but are borne from a specific geopolitical event and are created by a nation-state to perpetuate narratives that support their cause. Faketivists can be nation-state actors and/or proxy groups associated with the IRGC and the Ministry of Intelligence and Security (MOIS). The [cyberattacks in Israel](https://www.darkreading.com/threat-intelligence/iranian-apts-dress-up-as-hacktivists-for-disruption-influence-ops) that have deployed faketivists have had mixed success, but they have garnered both local and global support. The [purpose](https://www.darkreading.com/threat-intelligence/iranian-apts-dress-up-as-hacktivists-for-disruption-influence-ops) of these groups is to spread their “success” and to create disruption and attention, regardless of actual operational success. >Looking ahead, we can expect Iran to further integrate AI into its cyber strategy, escalating the frequency and sophistication of attacks, particularly on critical infrastructure and democratic processes. Additionally, the growing alignment between Iran and other global cyber powers, such as Russia and China, further increases the sophistication and reach of its cyber capabilities, presenting significant challenges for those attempting to counter these evolving threats.

    >Many microbes and cells are in deep sleep, waiting for the right moment to activate. >Harsh conditions like lack of food or cold weather can appear out of nowhere. In these dire straits, rather than keel over and die, many organisms have mastered the art of dormancy. They slow down their activity and metabolism. Then, w >Sitting around in a dormant state is actually the norm for the majority of life on Earth: By some estimates, 60% of all microbial cells are hibernating at any given time. Even in organisms whose entire bodies do not go dormant, like most mammals, some cellular populations within them rest and wait for the best time to activate. >“Life is mainly about being asleep.” >Because dormancy can be triggered by a variety of conditions, including starvation and drought, the scientists pursue this research with a practical goal in mind: “We can probably use this knowledge in order to engineer organisms that can tolerate warmer climates,” Melnikov said, “and therefore withstand climate change.” >Balon is notably absent from *Escherichia coli* and *Staphylococcus aureus*, the two most commonly studied bacteria and the most widely used models for cellular dormancy. By focusing on just a few lab organisms, scientists had missed a widespread hibernation tactic, Helena-Bueno said. “I tried to look into an under-studied corner of nature and happened to find something.” >“Most microbes are starving,” said [Ashley Shade](https://ashley17061.wixsite.com/shadelab), a microbiologist at the University of Lyon who was not involved in the new study. “They’re existing in a state of want. They’re not doubling. They’re not living their best life.” >“This is not something that’s unique to bacteria or archaea,” Lennon said. “Every organism in the tree of life has a way of achieving this strategy. They can pause their metabolism.” >“Before the invention of hibernation, the only way to live was to keep growing without interruptions,” Melnikov said. “Putting life on pause is a luxury.” >It’s also a type of population-level insurance. Some cells pursue dormancy by detecting environmental changes and responding accordingly. However, many bacteria use a stochastic strategy. “In randomly fluctuating environments, if you don’t go into dormancy sometimes, there’s a chance that the whole population will go extinct” through random encounters with disaster, Lennon said. In even the healthiest, happiest, fastest-growing cultures of *E. coli*, between 5% and 10% of the cells will nevertheless be dormant. They are the designated survivors who will live should something happen to their more active, vulnerable cousins. >More fundamentally, Melnikov and Helena-Bueno hope that the discovery of Balon and its ubiquity will help people reframe what is important in life. We all frequently go dormant, and many of us quite enjoy it. “We spend one-third of our life asleep, but we don’t talk about it at all,” Melnikov said. Instead of complaining about what we’re missing when we’re asleep, maybe we can experience it as a process that connects us to all life on Earth, including microbes sleeping deep in the Arctic permafrost.

    >Valtonen’s goal is to put CPUs back in their rightful, ‘central’ role. In order to do that, he and his team are proposing a new paradigm. Instead of trying to speed up computation by putting 16 identical CPU cores into, say, a laptop, a manufacturer could put 4 standard CPU cores and 64 of Flow Computing’s so-called parallel processing unit (PPU) cores into the same footprint, and achieve up to 100 times better performance.

    ## Highlights >America’s independent bookstores may look like the tattered, provincial shops of a bygone era—holding onto their existence by the slimmest thread. And booksellers may appear genial and absent-minded, like characters out of Dickens. But in reality, they’re the marketing geniuses of our time. >In August of last year *[Publishers Weekly](https://www.publishersweekly.com/pw/by-topic/industry-news/bookselling/article/92974-bookstore-sales-rose-nearly-7-in-first-half-of-2023.html#:~:text=Bookstore%2520sales%2520finished%2520the%2520first,to%2520$3.86%2520billion%2520this%2520year.)* reported, “Bookstore sales finished the first half of 2023 up 6.9% over the comparable period in 2022.” In fact, independent bookstore sales outpaced most other publishing industry metrics in 2023, growing faster than overall unit sales of print books. This is unprecedented. >Booksellers have bent the rules of the free market. For the first time in history, a significant chunk of the buying public are voluntarily paying almost double—and going out of their way—to buy exactly the same product they can get cheaper and often faster somewhere else. And it’s all due to that ABA message: “non-corporate, authentic, and socially responsible.” >What no one says is that the bargain works both ways. If book buyers must behave virtuously and tithe an additional $11 a book, then booksellers must uphold the community’s doctrines. They’re locked in the moral contract, too. >But books are different. They signal something about readers’ intelligence, identity, and closely held ideas. Books confer status—especially among the highly educated. The people who sell them know this and they used it to make their case. >“Most independent bookstores have succeeded because they’ve responded to the needs of their community,” says Jan Weissmiller, co-owner of Iowa City’s Prairie Lights since 2008. “If they’re in a part of the country where people are asking for a certain kind of book, that’s what they have on the shelf. Because they’re a business.” >But what I *really* want is a store where all the ideas are on display—the socialist, capitalist, monogamous, polyamorous, urban, rural, popular, and reviled—that also has the homely sacrosanct quality of one of Hemingway’s coffee-and-absinthe bars. With great music, please—and no puppets, or cheap pizza. Where are you buying books?

    >A strong majority of Americans across the political spectrum sympathize more with Ukraine than Russia in the ongoing war: 62% of respondents express more sympathy with Ukraine than Russia, including 58% of Republicans and 76% of Democrats. At the same time, just 2% of respondents said they sympathized more with Russia in the conflict, including 4% of Republicans and 1% of Democrats. Republicans (20%) were more likely than Democrats (7%) to say they sympathized with neither side, while equal numbers of Republicans and Democrats (5%) said they sympathized with both sides equally. >The percentage of respondents who said they want the United States to stay the course in supporting Ukraine grew from our October 2023 poll, reaching the highest level in our tracking since the spring of 2023. In our latest survey, 48% of all respondents said that the United States should support Ukraine as long as the conflict lasts, including 37% of Republicans and 63% of Democrats. All these numbers are new highs in our four polls since March-April 2023.

    ## Highlights >“Now, there’s no question China has been trying to crack down on the internet.” (*Chuckles.*) “Good luck!” (*Laughter.*) “That’s sort of like trying to nail Jell-O to the wall.” (*Laughter.*) >While we were still rhapsodizing about the many ways in which the internet could spread democracy, the Chinese were designing what’s become known as [the Great Firewall of China](https://www.politico.com/news/magazine/2020/09/01/china-great-firewall-generation-405385). >Even in a state where surveillance is almost total, the experience of tyranny and injustice can radicalize people. Anger at arbitrary power will always lead someone to start thinking about another system, a better way to run society. The strength of these demonstrations, and the broader anger they reflected, was enough to spook the Chinese Communist Party into lifting the quarantine and allowing the virus to spread. The deaths that resulted were preferable to public anger and protest. >If people are naturally drawn to the image of human rights, to the language of democracy, to the dream of freedom, then those concepts have to be poisoned. That requires more than surveillance, more than close observation of the population, more than a political system that defends against liberal ideas. It also requires an offensive plan: a narrative that damages both the idea of democracy everywhere in the world and the tools to deliver it. >This is the core problem for autocracies: The Russians, the Chinese, the Iranians, and others all know that the language of transparency, accountability, justice, and democracy appeals to some of their citizens, as it does to many people who live in dictatorships. Even the most sophisticated surveillance can’t wholly suppress it. The very ideas of democracy and freedom must be discredited—especially in the places where they have historically flourished. >Instead of portraying China as the perfect society, modern Chinese propaganda seeks to inculcate nationalist pride, based on China’s real experience of economic development, and to promote a Beijing model of progress through dictatorship and “order” that’s superior to [the chaos and violence of democracy](https://www.reuters.com/article/idUSKBN0EK08H/). >In September 2022, when Putin held a ceremony to mark his illegal annexation of southern and eastern Ukraine, he claimed that he was protecting Russia from the “satanic” West and “perversions that lead to degradation and extinction.” He did not speak of the people he had tortured or the Ukrainian children he had kidnapped. >Another strange actor in this field is RRN—the company’s name is an acronym, originally for Reliable Russian News, later changed to Reliable Recent News. Created in the aftermath of Russia’s invasion of Ukraine, RRN, part of a bigger information-laundering operation known to investigators as Doppelganger, is primarily a “typosquatter”: a company that registers domain names that look similar to real media domain names—Reuters.cfd instead of Reuters.com, for example—as well as websites with names that sound authentic (like *Notre Pays*, or “Our Country”) but are created to deceive. >None of these efforts would succeed without local actors who share the autocratic world’s goals. Russia, China, and Venezuela did not invent anti-Americanism in Mexico. They did not invent Catalan separatism, to name another movement that both Russian and Venezuelan social-media accounts supported, or the German far right, or France’s Marine Le Pen. All they do is amplify existing people and movements—whether anti-LGBTQ, anti-Semitic, anti-Muslim, anti-immigrant, anti-Ukrainian, or, above all, antidemocratic. >Here is a difficult truth: A part of the American political spectrum is not merely a passive recipient of the combined authoritarian narratives that come from Russia, China, and their ilk, but an active participant in creating and spreading them. Like the leaders of those countries, the American MAGA right also wants Americans to believe that their democracy is degenerate, their elections illegitimate, their civilization dying.

    ## Highlights >We may be close to rediscovering thousands of texts that had been lost for millennia. Their contents may reshape how we understand the Ancient World. >We don’t have original copies of anything, not of the *Iliad*, or the *Aeneid*, or Herodotus, or the Bible. Instead of originals, we find ourselves dealing with copies. These were first written on scrolls but later in books – the Romans called books *codexes* – starting in the first century AD. Did I say copies? That’s actually not correct either. We don’t have first copies of anything. What we do have is copies of copies, most of which date hundreds of years after the original was penned. Even many of our copies are not complete copies. >To most fully acclimate the reader to how tenuous this process is, this essay will focus on three different texts. The first will be a very well-known work that was never lost. Nevertheless, almost no one read it in earnest until the nineteenth century. I will then focus on a text that was lost to history, but that we were able to recover from the annals of time. Such examples are fortuitous. Our third example will be a text that we know existed, but of which we have no copies, and consider what important ramifications its discovery could hold. Finally, we’ll turn our attention again to the Villa of the Papyri and the gold mine of texts discovered there that new technologies are currently making available to classicists. >However, many of the scrolls from the Villa of the Papyri remain not only unread, but also unopened. This is because the eruption of Vesuvius left the scrolls carbonized, making it nearly impossible to open them. Despite this obstacle, Dr. Brent Seales pioneered a new technology in 2015 that allowed him and his team to read a scroll without opening it. The technique, using X-ray tomography and computer vision, is known as virtual unwrapping, and it was first used on one of the famous Dead Sea Scrolls, specifically the En-Gedi scroll, the earliest known copy of the Book of Leviticus (likely 210–390 CE). The X-rays allow scholars to create a virtual copy of the text that can then be read like any other ancient document by those with the proper language and paleography skills. Using Dr. Seales’s technique, scholars have been able to upload many of the texts online. A group of donors led by Nat Friedman and Daniel Gross have offered cash prizes to teams of classicists who can decipher the writings. The race to read the virtually unwrapped scrolls is known as the Vesuvius Challenge.

    ## Highlights >When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments. >A series of papers from the lab of [Carl Simpson](https://simpson-carl.github.io/) proposes an answer linked to a fundamental physical fact: As seawater gets colder, it gets more viscous, and therefore more difficult for very small organisms to navigate. Imagine swimming through honey rather than water. If microscopic organisms struggled to get enough food to survive under these conditions, as Simpson’s [modeling work](https://doi.org/10.1098/rspb.2023.2767) has implied, they would be placed under pressure to change — perhaps by developing ways to hang on to each other, form larger groups, and move through the water with greater force. Maybe some of these changes contributed to the beginning of multicellular animal life. >The experiment comes with a few caveats, and the paper has yet to be peer-reviewed; Simpson posted [a preprint on biorxiv.org](https://doi.org/10.1101/2024.02.06.579218) earlier this year. But it suggests that if Snowball Earth did act as a trigger for the evolution of complex life, it might be due to the physics of cold water. >It is [difficult to precisely date](https://doi.org/10.1126/sciadv.1600983) when animals arose, but an estimate from molecular clocks — which use mutation rates to estimate the passage of time — suggests that the last common ancestor of multicellular animals emerged during the era known as the Sturtian Snowball Earth, sometime between 717 million and 660 million years ago. Large, unmistakably multicellular animals appear in the fossil record tens of millions of years after the Earth melted following another, shorter Snowball Earth period around 635 million years ago. >The paradox — a planet seemingly hostile to life giving evolution a major push — continued to perplex Simpson throughout his schooling and into his professional life. In 2018, as an assistant professor, he had an insight: As seawater gets colder, it grows thicker. It’s basic physics — the density and viscosity of water molecules rises as the temperature drops. Under the conditions of Snowball Earth, the ocean would have been twice or even four times as viscous as it was before the planet froze over. >As large creatures, we don’t think much about the thickness of the fluids around us. It’s not a part of our daily lived experience, and we are so big that viscosity doesn’t impinge on us very much. The ability to move easily — relatively speaking — is something we take for granted. From the time Simpson first realized that such limits on movement could be a monumental obstacle to microscopic life, he hasn’t been able to stop thinking about it. Viscosity may have mattered quite a lot in the origins of complex life, whenever that was. >“Putting this into our repertoire of thinking about why these things evolved — that is the value of the entire thing,” he said. “It doesn’t matter if it was Snowball Earth. It doesn’t matter if it happened before or after. Just the idea that it can happen, and happen quickly.”

    ## Highlights >[Amanda Randles](https://bme.duke.edu/faculty/amanda-randles) wants to copy your body. If the computer scientist had her way, she’d have enough data — and processing power — to effectively clone you on her computer, run the clock forward, and see what your coronary arteries or red blood cells might do in a week. Fully personalized medical simulations, or “digital twins,” are still beyond our abilities, but Randles has pioneered computer models of blood flow over long durations that are already helping doctors noninvasively diagnose and treat diseases. >Her latest system takes 3D images of a patient’s blood vessels, then simulates and forecasts their expected fluid dynamics. Doctors who use the system can not only measure the usual stuff, like pulse and blood pressure, but also spy on the blood’s behavior inside the vessel. This lets them observe swirls in the bloodstream called vortices and the stresses felt by vessel walls — both of which are linked to heart disease. A decade ago, Randles’ team could simulate blood flow for only about 30 heartbeats, but today they can foresee over 700,000 heartbeats (about a week’s worth). And because their models are interactive, doctors can also predict what will happen if they take measures such as prescribing medicine or implanting a stent. >It’s a lot of data. We’re running simulations with up to 580 million red blood cells. There’s interactions with the fluid and red blood cells, the cells with each other, the cells with the walls — you’re trying to capture all of that. For each model, one time point might be half a terabyte, and there are millions of time steps in each heartbeat. It’s really computationally intense.

    I am really happy that the younger generation is re-evaluating views on work. ### From the article: ### >Yuki Watanabe used to spend 12 hours every day toiling away in the office. And that’s considered a short day. >Asking to leave work on time or taking some [time off](https://www.cnn.com/2023/03/26/asia/japan-paternity-leave-policy-challenges-intl-hnk-dst/index.html) can be tricky enough. Even trickier is tendering a resignation, which can be seen as the ultimate form of disrespect in the world’s fourth-biggest economy, where workers traditionally stick with one employer for decades, if not for a lifetime. >In the most extreme cases, grumpy bosses rip up resignation letters and harass employees to force them to stay. >...She turned to Momuri, a resignation agency that helps timid employees leave their intimidating bosses. >For the price of a fancy dinner, many Japanese workers hire these proxy firms to help them resign stress-free. >At a cost of 22,000 yen (about $150) – or 12,000 yen for those who work part time – it pledges to help employees tender their resignations, negotiate with their companies and provide recommendations for lawyers if legal disputes arise. >“Some people come to us after having their resignation letter ripped three times and employers not letting them quit even when they kneel down to the ground to bow,” she said, in another illustration of the deferential workplace culture embedded in Japan. >Japan has long had an overwork culture. Employees across [various sectors](https://www.mhlw.go.jp/content/11200000/001001666.pdf) report punishing hours, high pressure from supervisors and deference to the company. These employers are widely known as “black firms.” >Human resources professor Hiroshi Ono, from Hitotsubashi University Business School in Tokyo, said the situation had become so pressing that the government had begun publishing a list of unethical employers to hamper their ability to hire, and warn job seekers of the dangers of working for them. >So why did these resignation agents only emerge in recent years? That, experts say, is down to young people’s changing approach to work. >Many of them no longer subscribe to older generations’ thinking that one should do whatever they are told regardless of the job’s nature, Ono said, adding that when there is a mismatch of expectation, they won’t hesitate to quit. >“We honestly think that our resignation agency service should disappear from society and we hope for that. We think it’s best if people can tell their bosses themselves, but hearing the horror stories of our clients, I don’t think that our business will disappear anytime soon,” she said. >For now, Momuri offers a 50% discount for those who seek their service to resign the second time.

Divide Ellison's $18m among those workers and each of them would net a paltry $126/year. But if you were to share out the $43 billion Ellison had to piss up against a wall on stock buybacks among those workers, you'd be able to give *every worker a $30,000 bonus, every year*: >The largest 20 companies in the Low-Wage 100 spent nine times more on stock buybacks than they spent on worker retirement plan contributions. Chipotle spent $2b on buybacks – that's 48 times what the company put into its workers' 401(k)s. That's because 92% of Chipotle employees *can't afford to have a 401(k)*. >In incentivizing CEOs to keep share prices high above every other consideration, establishment economists set the stage for a corporate America where CEOs were punished for investing in a living wage, a dignified retirement, or even a non-lethal product. Instead, we have a business environment that boils down to a competition to see who can eat their seed-corn the fastest.

    Lessons Learned from Twenty Years of Site Reliability Engineering

    Metadata

    Highlights

    The riskiness of a mitigation should scale with the severity of the outage

    We, here in SRE, have had some interesting experiences in choosing a mitigation with more risks than the outage it's meant to resolve.

    We learned the hard way that during an incident, we should monitor and evaluate the severity of the situation and choose a mitigation path whose riskiness is appropriate for that severity.

    Recovery mechanisms should be fully tested before an emergency

    An emergency fire evacuation in a tall city building is a terrible opportunity to use a ladder for the first time.

    Testing recovery mechanisms has a fun side effect of reducing the risk of performing some of these actions. Since this messy outage, we've doubled down on testing.

    We were pretty sure that it would not lead to anything bad. But pretty sure is not 100% sure.

    A "Big Red Button" is a unique but highly practical safety feature: it should kick off a simple, easy-to-trigger action that reverts whatever triggered the undesirable state to (ideally) shut down whatever's happening.

    Unit tests alone are not enough - integration testing is also needed

    This lesson was learned during a Calendar outage in which our testing didn't follow the same path as real use, resulting in plenty of testing... that didn't help us assess how a change would perform in reality.

    Teams were expecting to be able to use Google Hangouts and Google Meet to manage the incident. But when 350M users were logged out of their devices and services... relying on these Google services was, in retrospect, kind of a bad call.

    It's easy to think of availability as either "fully up" or "fully down" ... but being able to offer a continuous minimum functionality with a degraded performance mode helps to offer a more consistent user experience.

    This next lesson is a recommendation to ensure that your last-line-of-defense system works as expected in extreme scenarios, such as natural disasters or cyber attacks, that result in loss of productivity or service availability.

    A useful activity can also be sitting your team down and working through how some of these scenarios could theoretically play out—tabletop game style. This can also be a fun opportunity to explore those terrifying "What Ifs", for example, "What if part of your network connectivity gets shut down unexpectedly?".

    In such instances, you can reduce your mean time to resolution (MTTR), by automating mitigating measures done by hand. If there's a clear signal that a particular failure is occurring, then why can't that mitigation be kicked off in an automated way? Sometimes it is better to use an automated mitigation first and save the root-causing for after user impact has been avoided.

    Having long delays between rollouts, especially in complex, multiple component systems, makes it extremely difficult to reason out the safety of a particular change. Frequent rollouts—with the proper testing in place— lead to fewer surprises from this class of failure.

    Having only one particular model of device to perform a critical function can make for simpler operations and maintenance. However, it means that if that model turns out to have a problem, that critical function is no longer being performed.

    Latent bugs in critical infrastructure can lurk undetected until a seemingly innocuous event triggers them. Maintaining a diverse infrastructure, while incurring costs of its own, can mean the difference between a troublesome outage and a total one.

    thank you, actually it seems that it is https://en.m.wikipedia.org/wiki/The_Sliced-Crosswise_Only-On-Tuesday_World , which has inspired Dayworld :)

    from the logs it would seem that synapse went down not due to share volume of traffic, but special malformed usernames - so it seems a different pattern was used (if it is was an attack)

    I am not sure if that is related, but technically Matrix uses a different protocol from ActivityPub, so it had to be targeted specifically
