Ask Slashdot: What are the Costs of Switching Between Windows, MacOS, and Chrome? 66

Posted by EditorDavid from the into-the-interface dept.
UI changes, lost productivity, untransferrable knowledge... Long-time Slashdot reader theodp notes the folly of switching to an unfamiliar new environment to be "more productive"... Champions of the switch often insist workers will be able to hit the ground running and get the same or even more work done from the get-go in the new unfamiliar environment because it's 'more productive', a conclusion often shaped by conventional wisdom or their 'gut' feeling. Decision makers may also mistake their own 'light-user experience' for universal experience and believe all platforms are fungible.

And while it's one thing for a business to delay their delivery dates and increase costs of by introducing a switch in computing environments that's of unquantified and possibly dubious value, how about when a switch in computing environments is made that affects schoolchildren's ability to learn for a period of time?

While a MacBook Neo is indeed cute, what might be the possible consequences of a decision to move 25,000 students off Windows and onto MacBook Neos...? Or even the impact on a single kid who moves from a MacBook school to a Windows or Chrome school (or whose home computing environment isn't aligned with their school). Or students whose teachers decide learning in their classrooms should now additionally require an understanding of the Minecraft computing platform/UI (used in over 40,000 school systems.). Learning Management Systems and now various AI Edtech tools used by schoolkids are also subject to change.
"Even if students and schools eventually benefit from a new platform, one wonders how much learning is lost during the switch," theodp asks, "and what the financial and educational ROI and payback period look like." Are there bigger problems than we realize? Share your own thoughts and experiences in the comments.

Yeah.

They completely ignore panserpmia.

They just quote Isaac Asimov's writing from almost half a century ago (Europa). Ignores Enceladus, Titan, Venus, Mars; all of which have *BIOSIGNATURES* of a probability curve not too dissimilar to Europa.

They are likely a dilettante. Those folks do not do "prior art" research because they believe in the Auteur Myth.

  "An auteur is a filmmaker whose personal style and thematic focus are so distinctive that they are considered the 'author' of their films, a concept known as the auteur myth."

Real science isn't that. Real science is a rational discipline. The null hypothesis -- know what that means. Prior art -- know what that means. Mental biases -- know those, too; you'll see what you want to see, hear what you want to hear. Science is the discipline of mind that ensures you're not just spewing random nonsense. You verify what you think; that's the discipline.

As Isaac Newton said ( https://en.wikipedia.org/wiki/... ), "nani gigantum humeris insidentes."

Ignore them.

How does a society treat its citizens, specifically parents and children?

Autism -- is human psychology being maladaptive because of this situation. Parents aren't there for their children to imprint-upon. The psychological distress is real. Depersonalization is a result.

This depersonalization happening during acute childhood development phases, exacerbates the problem of social disengagement.

Non-Invasive Stimulation of the Brain Ended Opioid Addiction, Cigarette Craving (jpost.com) 37

Posted by FirehoseFavorites from the second-chance dept.
The Jerusalem Post reports that doctors at Haifa's Rambam Health Care Campus "have successfully treated their first Israeli opioid addiction patient using an experimental noninvasive brain technology, easing him through withdrawal in just 20 minutes..." [T]he team of specialists at the Haifa medical center intervened in the electrical activity of an area of the patient's brain called the nucleus accumbens, the core of the brain system responsible for feelings of satisfaction, pleasure, and reward. The treatment, based on technology from the Israeli company Insightec, is similar to the one used to treat symptoms of essential tremor and Parkinsonian tremor, under MRI control. In this case, the treatment was carried out with the help of a new technology that performs noninvasive neuromodulation, without heating or burning tissue, and allows stimulation in the same area of the brain to increase or suppress activity...

"Tests carried out a week later produced negative results for opioids and other substances," [said Dr. Lior Lev-Tov, director of the functional neurosurgery unit in Rambam's neurosurgery division and the one leading the new study at the medical center.] "The patient himself reported a craving score of zero out of 10 for using the drug, and even another side effect, a drastic drop in the desire for cigarettes, from three packs a day to just a few cigarettes, and with no urge to use alcohol. In other words, in a treatment that lasted about 20 minutes net, our patient was completely freed from an extreme dependence that had accompanied him every day for years. This is nothing less than a medical and therapeutic revolution."
Dr. Lev-Tov added that "This experience opens doors for us to treat a wide range of very serious illnesses such as PTSD, OCD, eating disorders, other addictions, severe depression, severe pain disorders, and I hope we will also be able to reach cognitive areas and treat attention deficit disorders, Alzheimer's, Parkinson's, and more."

I'm still salty about the switch to SystemD in the first place. I grew up on the simplicity of Linux's three tenets:

1. Everything is a file
2. Everything should be kept as simple and discreet as possible
3. Text (ASCII) based files wherever possible for configs and logs

SystemD came along and just blew all three of those out of the water and made it look and act more like Windows with its complications. And now it's pushing non-needed items like Birthdate into the core functions.

Blue Origin Rocket Exploded Thursday Night During Hot-Fire Test (cbsnews.com) 73

Posted by EditorDavid from the space-is-hard dept.
Spaceflight Now shared their video of the explosion, which the Orlando Sentinel describes as showing Blue Origin's rocket "become engulfed in flames. The fireball expands out and covers the entire launch pad as the fuselage of the rocket can be seen crumbling into the flames."

Blue Origin founder Jeff Bezos said on X.com "It's too early to know the root cause but we're already working to find it. Very rough day, but we'll rebuild whatever needs rebuilding and get back to flying. It's worth it." (SpaceX founder Elon Musk posted "Sorry to see this, I hope you recover quickly.")

It's unclear how this will impact future launches. "The rocket was destroyed," reports CBS News, "and as the smoke cleared, there was no sign of the erector-gantry used to move the New Glenn from its hangar to the pad and to raise it from horizontal to vertical. Likewise, one of two tall lightning towers was no longer visible." It was the first such on-pad explosion at the Cape since a SpaceX Falcon 9 rocket blew up on nearby pad 40 on Sept. 1, 2016... Blue Origin only has one New Glenn pad, the one that was damaged in the Thursday test. The New Glenn, which has launched three times, is a heavy lift rocket designed to compete head-to-head with SpaceX Falcon 9 and Falcon Heavy rockets. During New Glenn's most recent flight in April, an upper stage malfunction prevented a commercial internet satellite from reaching its planned orbit...

The New Glenn destroyed Thursday was to send 48 Leo internet satellites owned by Amazon into space [which were not on board for the hot-fire test]
Blue Origin posted on X.com that "Debris from our recent hotfire anomaly may wash ashore in the coming days/weeks. If you encounter any debris, do not touch or approach it for your safety."

"Spaceflight is unforgiving, and developing new heavy-lift launch capability is extraordinarily difficult..." NASA Administrator Jared Isaacman posted on X.com. "âWe will provide information on any impacts to the Artemis and Moon Base programs as it becomes available."

"Despite the limitations of the 1993-era sound card drivers,"

The Gravis Ultrasound ( https://en.wikipedia.org/wiki/... ), as well as other soundcards which *USED WAVETABLE SYNTHESIS* were available.

Yeah, FM-synthesis sounds like a robot. The SNES SPC-7000 was wavetable. The Sega Genesis used a Z80 for FM synthesis. A GUS card was supperior to the SPC-7000.

If you want to know how good the music is, either run DOOM in DOSBOX with a correct GUS Wavetable patch set (which will let you know how *ACTUALLY GOOD* the music is). Alternatively, the Doom & Doom 2 remaster on Steam has an actual band covering the actual tracks. That also sounds awesome.

Lol; I guess the author wasn't aware of the state of the art in 1993 if that's what they wrote.

I, Steve Wozniak, did not participate in the theft of the BASIC. It was funny to me to see others enjoying doing this. I had never used BASIC myself, at that time, only the more-scientific languages like Fortran, Algol, and PL-1, and several assembly languages. I sniffed the air and sensed that you needed BASIC to sell computers into homes, because of the book 101 Games in BASIC. I loved games and saw games as the key. It was the [MS] BASIC that inspired me to write a BASIC interpreter for my 6502 processor, in order to have a more useful computer.

Scientists Found a Way To Cool Quantum Computers Using Noise (sciencedaily.com) 7

Posted by EditorDavid from the cool-technology dept.
Slashdot reader alternative_right writes: Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.

Comment Calculation Power? (Score 3, Interesting) 38

So maybe i'm missing something, but it's my understanding with most blockchain based applications the big thing is calculating "proof-of-ownership". However as the size of the chain increases, the calcuation power and time required to do it also increases (I don't remember if it's linearly, logrithmically, etc.). For a low volume application, this is feasible. But how would this work with things like HFT and massive volume changes in terms of time and compute power required.
