I'm using ZREP to replicate two servers with each other and each server contains one ZFS-pool containing two datasets as replication master and two sets as replication target. The master sets contain the system and VirtualBox-VMs of the local server, the replication targets the same from the other one. //

The problem.

But from time to time it happened that ZREP got into some state not able to sync anymore. To resolve that issue, a coworker told me that he needed to delete snapshots and follow the process to initialise ZREP again all over. That problem got fixed by not let ZREP run in parallel with rsync and our own snapshot anymore in the end.

ANSWER

Yes you still get all the data in-between but you just can't rewind to in-between.

If you have snapshot's 1,2 and 3 and the remote pool only has snapshot 1, you can give it snapshot 3 and skip 2.. it just won't be able to roll back to the '2' state. But the data will still be there.

The snapshots describe what was there at the time. So missing snapshot '2' on the remote pool, it's like you never took one at that point in time. It literally doesn't know about the '2' snapshot and what stuff looked like back then.

If you change your mind, you'll need to delete snapshot '3' on the remote pool and only then can you send '2', then '3' again.

Liberia's former President William Tolbert has had a symbolic reburial, 45 years after he was murdered during a coup and his body was believed to have been dumped in a mass grave.

Ten days after the president's killing, following trials by a kangaroo court, 13 of his cabinet were stripped, tied to stakes and then executed by a firing squad on a beach next to an army barracks in the capital, Monrovia.

None of the 14 corpses has been found but each man got a state funeral at a ceremony attended by President Joseph Boakai and other dignitaries.

The event was seen as an act of reconciliation and part of a process of the country coming to terms with its violent recent past.

"It is an act of national conscience. It is a moment to acknowledge historical wrongs and to reaffirm collective commitment to the truth, justice and reconciliation," President Boakai said. //

Doe himself met a violent death at the hands of rebels in 1990. His reburial in his home town last week was also ordered by the president.

"This is not just a burial; it is a moment of national reflection, a time to reconcile with our history, to heal from our wounds, and to remember with respect and purpose," Boakai said at Doe's funeral.

For the families of those executed in 1980, Tuesday's ceremony was both an act of remembrance and a way of bringing some respect to those who died.

How to Create ZFS File Systems

Caruso's experiment is amusing but also highlights the absolute confidence with which an AI can spout nonsense. Copilot (like ChatGPT) had likely been trained on the fundamentals of chess, but could not create strategies. The problem was compounded by the fact that what it understood the positions on the chessboard to be, versus reality, appeared to be markedly different.

The story's moral has to be: Beware of the confidence of chatbots. LLMs are apparently good at some things. A 45-year-old chess game is clearly not one of them. ® //

I just tried your query against ChatGPT to make an image of a chess opening board, it's hilarious. It's 8x7, with squares labelled A-H across the bottom but on the left and right sides it's got numbers 5,2,4,5,6,7 and blank. The pieces look weird, like the knights are mixed with rooks. And it seems like white has 2 queens whilst black has 2 kings. //

Barta was battling topical steroid withdrawal (TSW) syndrome, a debilitating condition some face after quitting high-potency creams to treat skin issues like eczema.

Common symptoms include intense burning, redness, itching and skin shedding. Many sufferers are bedridden or housebound for months — or even years — before the effects begin to subside, according to the International Topical Steroid Awareness Network (ITSAN), which advocates for awareness and supports those affected.

On June 23, New York’s Governor Hochul announced that she had directed the New York Power Authority to build a new nuclear energy facility with at least 1 GWe of capacity. During the announcement speech, she provided several bits of information leading to an informed prediction that the facility will initially include 4 BWRX-300’s on a site close to Lake Ontario. ///

Didn't New York just shut down a 1GWe (or more?) nuclear power plant near NYC just a couple of years ago in favor or "renewable energy"? So this is an acknowledgement that shutting it down was a mistake and waste of money.

Ron Howard's 1995 love letter to NASA's Apollo program takes a few historical liberties but it still inspires awe. //

This year marks the 30th anniversary of the 1995 Oscar-winning film, Apollo 13, director Ron Howard's masterful love letter to NASA's Apollo program in general and the eponymous space mission in particular. So we're taking the opportunity to revisit this riveting homage to American science, ingenuity, and daring. //

Howard ultimately shot most of the weightless scenes aboard the KC-135 since recreating those conditions on a soundstage and with CGI would have been prohibitively expensive.

In fact, Howard didn't rely on archival mission footage at all, insisting on shooting his own footage. That meant constructing realistic spacecraft interiors—incorporating some original Apollo materials—and reproducing exactly the pressure suits worn by astronauts. (The actors, once locked in, breathed air pumped into the suits just like the original Apollo astronauts.) The Mission Control set at Universal Studios was so realistic that one NASA consultant kept looking for the elevator when he left each day, only to remember he was on a movie set. //

Is every button pressed in the right way? No. Does it bug the crap out of me every time Kevin Bacon answers Tom Hanks' "How's the alignment?" question by nonsensically saying "GDC align" and pressing the GDC align button, which is neither what Lovell was asking nor the proper procedure to get the answer Lovell was looking for? Yes. But's also pure competence porn—an amazing love letter to the space program and the 400,000 men and women who put humans on the Moon.

And like Lovell says: "It's not a miracle. We just decided to go." //

For anyone wanting a more extensive Apollo 13 experience, then have a look at LunarModule5's YouTube channel.

They've created an end to end (from a few hours before launch, to a few after splashdown) series of videos. These use the entire recorded audio for the mission, both for the crew and controllers on the ground. Long periods of silence have been edited our, but enough silence/static gaps between audio, for the cuts not to feel strange. They've also included some backroom discussion recordings, to fill some of the empty sections audio.

The videos show a simulation (I don't know the software used) to visualise the events of the mission, as well as a huge collection of photos from the mission.

I've watched a few of the videos and plan at some point to watch them all (something like) end to end. However, as the set of mission videos comes in 19 parts, with many 10 hours long, for a total of about 120 hours, it's a serious commitment of time.

FWIW, and this is a throwaway here, Chrysler never really got the credit they deserved for their stellar work on those rockets, or on the electronic communication and diagnosis devices, which were quite advanced and reliable under tough circumstances. When Apollo ended, a lot of those guys went back to Detroit. Some of them worked on the racing program, doing aero and diagnostic work; others worked on electronic ignition and on-board automotive computers. They did all this for relatively small profits.

Those Mission Control consoles were built by Ford (Philco division.https://www.youtube.com/watch?v=1XbEIMcxl04)

Most fittingly, the Lunar Roving Vehicle was built in part by General Motors.

And with all that fresh space-age engineering experience under their belts, the American auto industry...basically fell apart at the seams for the next decade. //

With these comments, Pulte is demonstrating that he, like his boss Donald Trump, subscribes to the standard Yellen-Bernanke inflationist model of monetary policy: the job of the central bank is to forever force down interest rates, churn out more easy money, and devalue the currency.

Pulte claims publicly that this somehow makes homes more affordable. As we’ll see below, though, the Fed’s easy-money policy of recent decades has not made home more affordable. Rather, Fed policy has helped to relentless increase home prices through the Fed’s asset purchases, interest rate policy, and monetary inflation. //

There are many factors that affect mortgage rates, of course, but over the past thirty years—and especially since 2009—falling interest rates have coincided with rising home prices. In fact, falling interest rates slightly precede rising home prices, suggesting a causal relationship.

I created this site to enable people to compare many so-called “secure messaging apps”. Likewise, I hope to educate people as to which functionality is required for truly secure messaging.

In 2016, I was frustrated with the EFF’s very out-of-date comparison, and hence I decided to create a comparison myself. Reaching out to various privacy organisations proved to be a complete waste of time, as no one was willing to collaborate on a comparison. This is a good lesson learnt: Don’t be beholden to other people/organisations, and produce your own useful work.

This site is not meant to be comprehensive; security is difficult, and a full review of each app is simply not plausible due to time, a lack of access to source code in many cases, and a lack of knowledge of development practices, and general cyber security maturity.

CNN weekend host Michael Smerconish spent more than six minutes in his opening, detailing Trump's accomplishments over the past 12 days. //

Winning became a punchline that Trump’s opponents used to lampoon him in his first administration. He was a political novice then, surrounded by a team with which he was unfamiliar, and he was probably as surprised as the rest of us were that he won the election.

This time is different. This time he came with a plan and a cabinet with senior advisers comprised of loyalists, all well known to the president. And recently, he’s exhibited a more layered approach to governing on both the domestic and international front, no longer solely guided by winning each day’s news cycle.

By any objective measure, President Trump has his opponents on the run.

The question seemed easy enough: We’ve dropped a user, now we want to change the DEFINER on all database objects that currently have it set to this dropped user?

This should be possible by checking the INFORMATION_SCHEMA tables of the appropriate object types (routines, triggers, views and events) and performing an ALTER on each of them that just modifies the DEFINER but nothing else, right?

Unfortunately it isn’t that easy, or at least not yet (see http://bugs.mysql.com/73894 and https://mariadb.atlassian.net/browse/MDEV-6731 ).

“If you are in a boring meeting or driving or otherwise in the middle of something where nodding off is unacceptable, just hold your breath,” one person shared.

“If you hold it long enough, your body will send a rush of blood to your brain, which in turn will make you suddenly feel wide awake. The effect is not long-lived, though, but it can save you when you just need to stay awake and alert for just a bit longer.” //

“If you get a mosquito bite, run a spoon under hot water (not hot enough to burn obvs) and then press the back it to the bite, and repeat that a couple times — it helps ‘cook’ the itchy protein so that you don’t have that large histamine reaction!” advised another user.

“If you burn your tongue, put sugar on it,” suggested one person.

“Was in Mexico with a partner several years ago, and he got overconfident with hot sauce. He started freaking out and the waiter came over and advised him to pour a sugar packet on his tongue. It worked almost immediately, and I’ve always wondered if it was psychosomatic or a real thing!” someone wrote. //

“Sniff alcohol wipes when nauseous. Or in a pinch, hand sanitizer. The isopropyl alcohol somehow instantly stops nausea, even faster and more efficiently than ondansetron,”

The scheme highlights still unaddressed vulnerabilities in the voting process that leave elections ripe for fraud. //

In Pennsylvania, where officials swear elections are safe and secure, three elected officials are headed to prison after admitting they cheated in the 2021 election. Their cases reveal common vulnerabilities in the voting process that have yet to be cured.

The three men, who all at one time were elected Democrat members of the Millbourne Borough Council, tried to rig the mayoral election in favor of one of them. They failed by 30 votes, got caught, and in June each was sentenced to prison. Among the charges were conspiracy to commit voter fraud, giving false information in registering to vote, and fraudulent voter registration. //

The scheme highlights how easily electronic voter registration and ballot requests, drop off boxes, signatures, photo identification, and in-person voting each have a role in allowing or preventing election fraud. If they had been forced to vote in person and verify their address with a photo ID, this cheating would not have happened.

Rwanda and Congo Sign U.S.-Brokered Peace Treaty
President Trump claims credit for the outcome. The main question now is how the treaty will be implemented as fighting still rages in eastern Congo.

This supposed falling out may be making a mountain out of a molehill. In 1931, the American chewing gum model William Wrigley Jr., speaking to "The American Magazine," said:

Business is built by men who care—care enough to disagree, fight it out to a finish, get facts. When two men always agree, one of them is unnecessary.

Writing for the majority, Associate Justice Amy Coney Barrett did not mince words when criticizing the lack of legal rationale behind the Biden appointee’s emotionally-charged dissent. //

While noting how the principal dissent authored by Associate Justice Sonia Sotomayor “focuses on conventional legal terrain, like the Judiciary Act of 1789 and our cases on equity,” Barrett highlighted how Jackson’s dissent “chooses a startling line of attack that is tethered neither to these sources nor, frankly, to any doctrine whatsoever.” More specifically, she underscored how her Democrat-appointed colleague’s expressed views on the power of courts go beyond those of judicial supremacists — those who believe the judiciary is superior to the other branches of government. //

“Waving away attention to the limits on judicial power as a ‘mind-numbingly technical query,’ post, at 3 (dissenting opinion), [Jackson] offers a vision of the judicial role that would make even the most ardent defender of judicial supremacy blush. In her telling, the fundamental role of courts is to ‘order everyone (including the Executive) to follow the law—full stop.'” //

“We will not dwell on JUSTICE JACKSON’s argument, which is at odds with more than two centuries’ worth of precedent, not to mention the Constitution itself. We observe only this: JUSTICE JACKSON decries an imperial Executive while embracing an imperial Judiciary.“ //

While agreeing that the executive has an obligation to follow the law, Barrett chastised Jackson for “skip[ping] over” the fact that the judiciary must do so as well, and that separation of powers must be upheld.

“JUSTICE JACKSON would do well to heed her own admonition: ‘[E]veryone, from the President on down, is bound by law.’ … That goes for judges too.”
