Where the CHIPS Act money has gone
  • Yes, but I don't think the CHIPS Act was aimed at the not-so-cutting-edge processes and getting those reshored onto US soil. The US already has a bunch, and the strategic value of those supply chains are less critical to national interests.

  • Apple is bringing RCS to the iPhone in iOS 18 | The new standard will replace SMS as the default communication protocol between Android and iOS devices
  • Fi has two different, incompatible options for how to sync your messages to a computer or other device that isn't your primary phone with your SIM (or e-SIM): the so-called "option 1" is RCS compatible, but treats your phone as the canonical device that has the primary copy of all messages, voicemails, etc. "Option 2" is device agnostic, where all messages and voicemails live on the cloud, and your phone (and all other devices) merely syncs with that primary copy in the cloud.

    If your phone breaks or dies or is lost/stolen, Option 2 keeps chugging along with all your logged in devices, but the dead phone is the single point of failure for Option 1.

    Ideally there would be a device agnostic way to access RCS through your account, but every implementation seems to require a specific SIM.

  • PSA: Alternatives for the most popular lemmy.ml communities
  • I think that it's foolish to concentrate people and activity there even further, it defeats the point of a federation.

    It defeats some of the points of federation, but there are still a lot of reasons why federation is still worth doing even if there's essentially one dominant provider. Not least of which is that sometimes the dominant provider does get displaced over time. We've seen it happen with email a few times, where the dominant provider loses market share to upstarts, one of whom becomes the new dominant provider in some specific use case (enterprise vs consumer, mobile vs desktop vs automation/scripting, differences by nation or language), and where the federation between those still allows the systems to communicate with each other.

    Applied to Lemmy/kbin/mbin and other forum-like social link aggregators, I could see LW being dominant in the English-speaking, American side of things, but with robust options outside of English language or communities physically located outside of North America. And we'll all still be able to interact.

  • A PR disaster: Microsoft has lost trust with its users, and Windows Recall is the straw that broke the camel's back
  • When they announced Win7, I downloaded Ubuntu 6.06, “Dapper Drake”.

    Windows Vista was so bad that it gets forgotten even in a retrospective about how Windows versions sucked. But yeah, Win7 didn't come out for another few years after that, to rescue the world from Vista.

  • How Much Energy Would It Take to Pull Carbon Dioxide out of the Air?
  • Targeting the preindustrial level of atmospheric CO2 is such an ambitious target, trying to undo 300 years of emissions. Then again, it's not like we've stopped emitting.

    If we instead try to calculate the energy requirements to simply offset the average emissions of that particular year, using this formula of 652 kJ/kg CO2, and average annual CO2 emissions, against the current numbers of about 37 billion tonnes, or 37,000,000,000,000 kg, we have 2.4 x 10^16 kJ, or 2.4 x 10^19 joules. Which converts to 6.7 x 10^12 kWh, or 6,700 TWh.

    Total annual US electricity generation is about 4700 TWh per year.

    Global electricity generation is about 25000 TWh per year, about 40% of which is from low or zero carbon sources.

    So basically if we've got 6700 TWh of clean energy to spare, it would be more effective to steer that into replacing fossil fuels first, and then once we hit a point of diminishing returns there, explore the much less efficient options of direct capture for excess energy we can't store or transport. Maybe we'll get there in a decade or two, but for now it doesn't make any sense.

  • Microsoft has blocked the bypass that allowed you to create a local account during Windows 11 setup by typing in a blocked email address
  • they have such a monopoly

    The major weakness in their desktop OS market dominance isn't from other desktop OSes. MacOS, ChromeOS, and traditional desktop Linux distros prevent Windows from being a total monopoly, but there's no doubt that Windows has quite a bit of market power.

    The real competitive threat to Windows is from people who decide to not use a desktop computer at all. Between tablets and phones, there are a lot of people who no longer feel the need to have a laptop or desktop at all, for personal use.

    And on that front, Windows being shittier than phones and tablets will cause people to slow down their upgrade cycle and maybe avoid using a traditional personal computer at all.

  • What is/was your distrohopping journey?
  • For my personal devices:

    • Microsoft products from MS DOS 6.x or so through Windows Vista
    • Ubuntu 6.06 through maybe 9.04 or so
    • Arch Linux from 2009 through 2015
    • MacOS from 2011 through current
    • Arch Linux from 2022 through current

    I've worked with work systems that used RedHat and Ubuntu back in the late 2000's, plus decades of work computers with Windows. But I'm no longer in a technical career field so I haven't kept on top of the latest and greatest.

  • Small modular nuclear reactors get a reality check in new report
  • So why don't we do it? FUD.

    A consortium of Utah's utilities (UAMPS) literally just pulled out of its commitment to backing NuScale's modular reactor in November 2023. It was a problem of cost, when the construction looked like it was going to become too expensive, at a time when new wind construction is dropping the price of wind power. It basically just couldn't compete on cost, in the specific environment of servicing Utah.

    geothermal is probably expensive due to hard rock

    I wouldn't sleep on geothermal as a future broad scale solution for dispatchable (that is, generation that can be dialed up and down on demand) electrical power. The oil and gas fracking industry has greatly improved their technology at imaging geological formations and finding places where water can flow and be pumped, in just the past decade. I expect to see over the next decade geothermal reach viability beyond just the places where geothermal heat is close to the surface.

  • Small modular nuclear reactors get a reality check in new report
  • We can’t talk about things like this like they’re free.

    Some shifts genuinely are free, though. Wholesale prices for electricity follow a pronounced "duck curve," and drop to near zero (or even negative) in areas where there's a substantial solar base, during the day at certain parts of the year. People will shift their demand for non-time-sensitive consumption (heating, cooling, charging of devices/EVs, batched/scheduled jobs) in response to basic price signals. If a substantial amount of future demand is going to be from data centers performing batched/scheduled jobs, like training AI models or encoding video files, a lot of that demand can be algorithmically shifted.

    There are already companies out there intentionally arbitraging the price differences by time of day to invest in large scale storage. That's an expensive activity, that they've determined is worth doing because there's profit to be made at scale.

    At household scale, individuals can do that too.

    Put another way, we shouldn't talk about current pricing models where every kilowatt hour costs the same as if that arrangement is free.

    Plus, the timing of consumption already does naturally tend to follow the timing of solar generation. Most people are more active during the day than at night, and work hours reflect that distribution. Overcapacity in solar can go a long way towards meeting demand when it naturally happens.

  • Small modular nuclear reactors get a reality check in new report
  • Up our storage game, big time

    I think this can be expanded out a bit, to the more generalizable case of matching generation to demand. Yes, storage can be a big part of that.

    But another solution along the same lines may be demand shifting, which in many ways, relies on storage (charging car batteries, reheating water tanks or even molten salt only when supply is plentiful. And some of that might not be storage, per se, but creating the useful output of something that actually requires a lot of power: timing out industrial processes or data center computational tasks based on the availability of excess electrical power.

    Similarly, improvements in transmission across wide geographical areas can better match supply to demand. The energy can still be used in real time, but a robust enough transmission network can get the power from the place that happens to have good generation conditions at that time to the place that actually wants to use that power.

    There's a lot of improvement to be made in simply better matching supply and demand. And improvements there might justify intentional overbuilding, where generators know that they'll need to curtail generation during periods where there's more supply than demand.

    And with better transmission, then existing nuclear plants might be able to act as dispatchable backup power rather than the primary, and therefore serve a larger market.

  • Small modular nuclear reactors get a reality check in new report
  • When costs are level per kilowatt over lifetime Nuclear is cheaper thanks to economies of scale

    Citation needed.

    Vogtle added 2000 megawatts of capacity for $35 billion over the past 15 years. That's an up-front capital cost of $17,500 per watt. Even spread over a 75 year expected lifespan, we're talking about $233 per watt per year, of capital costs alone.

    Maintenance and operation (and oh, by the way, nuclear is one of the most labor intensive forms of energy generation, so you'll have to look at 75 years of wage increases too) and interest and decommissioning will add to that.

    So factoring everything in, estimates are that it will work out to be about $170/MWh, or $0.17 per kwh for generation (before accounting for transmission and reinvestment and profit for the for-profit operators). That's just not cost competitive with anything else on the market.

    Economies of scale is basically the opposite of the problem that 21st century nuclear has encountered, which is why the current push is to smaller reactors, not bigger.

    There's a place for extending nuclear power plant lifespans as long as they'll go. There's less of a place for building new nuclear.

  • Framework Laptop 13 gets Intel Core Ultra with a 120 Hz display, and cheaper AMD models
  • When they say modules, does that mean mainboards?

    They mean each part. Here's their store for individual parts.

    This announcement includes a new display, so anyone with the old display can swap out their old one for the new one. People can swap out batteries. Keyboards. Touchpads. It's a modular design so that each module can be swapped out if broken, or if there's been an upgrade the user wants.

  • How does SecureErase work?
  • I sync if I have a good Internet connection, like from my hotel room or whatever, by VPNing into my home network where my NAS is. There are distributed DNS type solutions for a lot of the big NAS brands, where they'll let you access your data through their service, but I never set that up because I already have a VPN. So my NAS and firewall are configured not to allow outside connections to that device.

    But if I haven't synced laptop to NAS yet, then copies exist on both my camera SD cards (redundant double SD card) and my laptop.

  • How does SecureErase work?
  • 3-2-1 backup is important. I've been burned with lost files before, so I now make sure they're available in multiple places.

    I also encrypt everything. My laptops can't be unlocked by anyone except myself: Apple Filevault on my Apple laptop, LVM on LUKS on my Linux laptop. If something happens to me, my laptops must be wiped completely to be useable as a used device.

    My NAS keeps my backups of all my documents and media (and as a hobbyist photographer, I have over a terabyte of photos and videos I've taken). It's encrypted, but I've written the key down on paper and put it in my physical documents. If something happens to me, someone who goes through my physical documents will have access to my digital files.

    I pay a cloud service (Backblaze) for cloud backups. I trust the encryption and key management to not actually give the service provider any access to my files.

  • We found this old matchbook in our kitchen. It's for a coroner's election. The Democrat candidate is on one side and the Republican candidate is on the other.
  • Oh I actually know this one. Mostly historical accident and path dependence.

    In medieval England, kings wanted to make sure that taxes and fines to the crown were properly paid, so they had their own officials in each county, who reported to the King rather than to any local officials. Sheriffs were responsible for tax collection, law enforcement (both arresting people before they could be tried and carrying out the rulings of the court). But they'd have to wait for the king's courts to actually come to town and hold trials and what not, so in the meantime the king's financial interests weren't necessarily aligned with the sheriff's.

    So coroners were appointed to watch over county matters and represent the king's financial interests whenever the courts came to town.

    When someone was convicted of a capital offense, their property escheated to the crown. That was an important source of revenue for the crown, so coroners would determine whether a dead body was the result of a crime or not, in order to make sure the crown wasn't missing out on some convict money.

    Both the Sheriff and coroner positions survived the transition into American governance, but independence and democratic reforms meant that these previously crown-appointed positions needed to become elected positions. Most states kept Sheriffs and Coroners as county officials, and preserved some of their traditional roles and duties. Many coroners offices were renamed to "medical examiner" but basically still preserved the role of keeping stats on deaths. And without appointment by the crown, most states just chose to make these elected positions.

    What's your setup for storing, using, sharing, and backing up your files?

    Curious what everyone else is doing with all the files that are generated by photography as a hobby/interest/profession. What's your working setup, how do you share with others, and how are you backing things up?
