Comment 12-15 seconds (Score 1) 134

by nickwinlund77 (#66003872) Attached to: Ask Slashdot: What's Your Boot Time?

Recently I was building an AMD-based PC system for a client. I started with 32 GB of DDR5 and there was some kind of systemic lag occurring while I was making changes in this PC's mobo UEFI BIOS settings. My USB mouse was lagging inexplicably. I eventually recalled that the usual A-B-A-B method for assigning dissimilar memory still applies. When I inserted my memory in the correct order everything seemed fine.

Undaunted, I got this system with its two SSD's each separately running Ubuntu Budgie and Windows 11 to boot, however my boot time is now on the order of 12 to 15 seconds start time. This seems an extra long time from my viewpoint. In the past — a similar setup would take 5 to 7 seconds, tops.

Incidentally, the pre "pre-alpha" releases of KDELinux are available only in raw (not ISO) format, and so one has to use an AppImage program called KDE ISO Image Writer on another Linux machine or your other Windows machine to burn the *.raw KDELinux installation image to your USB thumb drive.

Saw this on KDE Linux's webpage: "Lots of internal Plasma-aligned apps haven't been Flatpak'd yet (Icon Explorer, Emoji Picker, Info Center, etc) and should be."

This could mean that the installer is itself a Plasma-aligned app. Maybe that's why I encountered a fatal install error. I don't think it's my GPU because the system launches into desktop mode quickly.

I'm just a software progressive -- I don't work directly with KDE Linux's developers. I also won't tell -- or really push the envelope in any way. I'm now aware in a sense that some of our global competitors would rather not see these people succeed.

Comment flatpak issue with the pre "pre-alpha" release (Score 3, Interesting) 28

I'm going to check out the pre-alpha release! I was having just one install problem:

My attempt at installing KDE Linux several days ago complained about a /system/@flatpak configuration that went awry. The read-only filesystem KDE Linux uses creates an interesting problem for the user if something internal is not working correctly during the Linux installation. I didn't know or couldn't understand how to take out entries that were using flatpak IN THE INSTALLER itself (likely due to the read-only filesystem). I was only able to somehow modify a *.conf file and doing this did nothing to fix the broken installer.

"You can only install sandboxed apps that go in their own corner of the OS, and here the plan is that users will install Flatpak (and possibly Snap, "if it's not too hard and the UX is OK") packages using the KDE Discover app"

^ That is a major "no shit" statement right there. It really took me a while to learn this.

I don't think Wi-Fi drivers for RPi 4 or RPi 5 will ever be supported by AARCH64 FreeBSD. Every time I look into this I get a NIMBY vibe from the FreeBSD devs. They just don't care about something that small.

What's astonishing to me is that FreeBSD, after all of this time, still does not have an additional part included in their installer to install and test Xorg and say, XFCE or GNOME desktop environments. That right there just seems to be "in error" and does not sit well with me. Sure, I could use Ghost BSD or something else. It does beg the question: why does FreeBSD do this to their whole base? Do they enjoy making the non-server crowds who run FreeBSD on their PC's and laptops miserable?

Submission + - Study solves long-standing mystery of what may have triggered ice age (phys.org)

A new study led by University of Arizona researchers may have solved two mysteries that have long puzzled paleo-climate experts: Where did the ice sheets that rang in the last ice age more than 100,000 years ago come from, and how could they grow so quickly?

Understanding what drives Earth's glacial–interglacial cycles—the periodic advance and retreat of ice sheets in the Northern Hemisphere—is no easy feat, and researchers have devoted substantial effort to explaining the expansion and shrinking of large ice masses over thousands of years. The new study, published in the journal Nature Geoscience, proposes an explanation for the rapid expansion of the ice sheets that covered much of the Northern Hemisphere during the most recent ice age, and the findings could also apply to other glacial periods throughout Earth's history.

About 100,000 years ago, when mammoths roamed the Earth, the Northern Hemisphere climate plummeted into a deep freeze that allowed massive ice sheets to form. Over a period of about 10,000 years, local mountain glaciers grew and formed large ice sheets covering much of today's Canada, Siberia and northern Europe.

While it has been widely accepted that periodic "wobbling" in the Earth's orbit around the sun triggered cooling in the Northern Hemisphere summer that caused the onset of widespread glaciation, scientists have struggled to explain the extensive ice sheets covering much of Scandinavia and northern Europe, where temperatures are much more mild. ...

"Using both climate model simulations and marine sediment analysis, we show that ice forming in northern Canada can obstruct ocean gateways and divert water transport from the Arctic into the North Atlantic," Lofverstrom said, "and that in turn leads to a weakened ocean circulation and cold conditions off the coast of Scandinavia, which is sufficient to start growing ice in that region."

Submission + - California Ran on Nearly 100% Clean Energy This Month (bloombergquint.com)

Submitted by Anonymous Coward
An anonymous reader writes: California, which aims to have a carbon-free power grid within 25 years, got a short glimpse of that possibility earlier this month. The state’s main grid ran on more than 97% renewable energy at 3:39 p.m. on Sunday April 3, breaking a previous record of 96.4% that was set just a week earlier, the California Independent System Operator said Thursday in a statement. While these all-time highs are for a brief time, they solidly demonstrate the advances being made to reliably achieve California’s clean energy goals,” said California ISO CEO Elliot Mainzer said in the statement.

Power production from the sun and wind typically peak in the spring, due to mild temperatures and the angle of the sun allowing for an extended period of strong solar production, the grid operator said. While hitting the new renewable record is remarkable, the state has found itself scrambling for power supplies during the past two summers as it has added more intermittent sources and retired natural-gas plants for environmental reasons. California has set a target to have a zero-carbon power system by 2045.
