Trump Admin Announces $17.5 Billion In Loans For 10 New Large Nuclear Reactors

An anonymous reader quotes a report from the Associated Press: The Trump administration is providing $17.5 billion to speed the development of 10 new large nuclear reactors to meet the skyrocketing power demand from massive data centers. Energy Secretary Chris Wright cited "tremendous interest" among developers of data centers that would buy the power, as well as utilities and energy companies. The nuclear plants could begin construction by 2030 and become operational in the mid-2030s, Wright and other officials said Tuesday. "This is the start," Wright said on a call with reporters. "We're going to move with the players that are ready to stand up and move quickly. Once that supply chain is up and running, do we think there will be dozens of these built going forward? I'd be very surprised if there were not." Most U.S. nuclear power plants were built between 1970 and 1990. Only two new large reactors have been built from scratch in the United States in recent decades. Those two reactors, at Georgia Power Co.'s Plant Vogtle, were completed years late and billions of dollars over budget. The 10 new reactors will use the same design, Westinghouse's AP1000. Wright said the Plant Vogtle project struggled because of bad planning, supply chain problems and the COVID-19 pandemic. But, he said, the reactor design is "robust and sound."

A 25-Year-Old Blog Looks Back At 40 Years of Computing

Ancient Slashdot reader Mark Round writes: Longtime reader here (since mid-1999 -- Hot Grits! Oog the Caveman! Beowulf clusters!), and I can still remember posting back on Slashdot's own 5th anniversary. Time's rolled on: my own blog just turned 25, and it's now roughly 40 years since I first sat down at a computer. So I went digging through archive.org, old backups, and a box of ZIP disks, and wrote up a long look back at four decades of computing through the one website that's been my online home along the way. It runs from my first 8-bit micro and a 1,200-baud modem through discovering the actual Internet at university (and burning far too many hours on Slashdot and sister sites like freshmeat.net), past gloriously pimped-out Enlightenment Linux desktops, all the way to the modern cloud-native world. Plenty of dodgy screenshots, terrible code, and fond memories of long-gone haunts like kuro5hin.org and Linux Coffee Talk along the way.

Mushroom Behind 'Tiny Human' Visions Lacks Genes For Known Psychedelics

alternative_right shares a report from ScienceAlert: If you consumed a wild mushroom and suddenly started seeing tiny people around you, you might reasonably assume it contained a familiar psychedelic. But that does not appear to be the case with Lanmaoa asiatica, known locally as jian shou qing, a mushroom species sold in markets in Yunnan, southwestern China. When eaten undercooked, the mushroom can produce vivid visions of miniature people -- not unlike Gulliver on his travels to Lilliput. To try and find out the root cause, University of Utah mycologists Colin Domnauer and Bryn Dentinger sequenced the genomes of 53 mushroom samples from across the wider Lanmaoa genus. And despite the reported hallucinations, they found no close matches to genes associated with psilocybin or ibotenic acid, two well-known mushroom hallucinogens whose biosynthetic pathways were specifically examined in the study. "Biosynthetic gene mining of the L. asiatica genome found no close hits with any genes known in the production of mushroom psychoactive compounds," write the researchers in their published paper. "This supports our hypothesis of the presence of a novel unidentified metabolite responsible for the unique hallucinogenic properties of L. asiatica." [...] Whatever chemical pathways are causing these effects in the brain, the responsible compound appears to be something scientists have not yet identified. [...] By identifying 1,515 corresponding genes across the selected specimens, the researchers obtained a clearer answer to the question of what defines a mushroom species as part of the genus Lanmaoa. There are now 17 recognized species in the genus, including four that haven't been identified before, two of which the researchers specifically named here: Lanmaoa fallax and Lanmaoa carbonilivor. The researchers say the Lanmaoa family and evolutionary tree can now be more fully mapped out, and some existing specimens may need to be reclassified.

In memory of the man who put red and green squiggles under words

Every little thing in a graphical user interface that we take for granted today, no matter how small, was thought up by someone, at some point. Case in point: the little red squiggly lines underneath misspelled words. In one form or another, these are everywhere now, and have just become a regular staple of every single text editing field we encounter every single day and don't stop to think about. Still, they were invented by someone, and we happen to know exactly who that was: Tony Krueger. In early versions of Word, the Spell Check feature was something that you explicitly invoked, and then you had to sit and wait while the program looked for all your potentially-misspelled words, and then showed them to you one at a time for a decision on what to do for each one. Word did introduce an Auto Spell Check feature to run spell check when the user was idle, so that when you hit the Spell Check button, the results were ready to go. However, the Auto Spell Check was still a blocking operation. As a result, a lot of users turned it off because it always seemed to decide "Now would be a good time to spell-check the document" just as you wanted to do something, forcing you to wait for the spell check pass to complete before you could, say, save and exit. Tony made the spell checker much more unobtrusive so that it didn't interfere with your foreground work. And when it found a problem, instead of waiting for you to trigger a spell check, it immediately drew red squiggles under potentially-misspelled words (and later green squiggles under potential grammatical errors). ↫ Raymond Chen at The Old New Thing Tony Krueger passed away recently, after, among other things, having worked on an dizzying number of Microsoft Word releases. Imagine coming up with something that seems to basic and elementary to us now, and seeing it spread pretty much everywhere. I wonder what it must feel like to have invented something that seems so simple, most people don't even realise they use it every single day.

KDE is going to fix network shares

I've had my share of issues with network shares on any operating system, but since I mostly use KDE these days I found this deep dive into how, exactly, network shares work in KDE quite interesting. It turns out that while network shares in KDE's Dolphin mostly work, it does involves a few layers that sometimes don't interact well with each other, leading to really curious and annoying problems with mounted shares not appearing, permission issues, and so on. The biggest cause of problems is when using a non-KDE application in KDE that also happens to use a non-KDE save/open dialog. Such a non-KDE save/open dialog won't be able to see any network shared mounted by KDE, and sadly, quite a few applications you're likely to use on a KDE installation use non-KDE open/save dialogs, like Blender, GIMP, LibreOffice, OnlyOffice, Inkscape, Audacity, DaVinci Resolve, and more. That's one hell of a list of applications to offer inconsistent or outright broken access to network shares you've set up and mounted in KDE. Luckily, this issue seems to be getting a ton of attention soon. All is not lost. Happily, KDE just received an investment of over €1.2 million from the Sovereign Tech Fund, and it includes funding for improvements to KDE's network share handling! ↫ Nate Graham The project is in the planning phases at the moment, but they're considering a whole slew of possible changes, fixes, and workarounds to make this stupid and annoying problem just go away. In 2026, nobody should be dealing with manually editing /etc/fstab or getting frustrated over supposedly disappearing network shares.

Xfce’s new Wayland compositor sees first alpha release

The developer working on Xfwl4, the Wayland compositor for Xfce, has published the new compositor's very first alpha release. Considering it's only been six months or so of work, it's impressive to see the effort reach this state already. The end goal of xfwl4 is to behave as closely as possible to an Xfce desktop running on an X server. Ideally a user could switch between the two without even knowing there's a difference. In reality, of course, it won't be quite that seamless, and there's still more work to be done to get as close as possible to that ideal. This is a first solid cut at it, at the very least. ↫ Brian Tarricone Being the very first alpha release, it won't surprise you there's a few things missing or broken at this point. Still, if you're brave, you can download and build the release and try it out.
