Which of the 3 standard compression algorithms on Unix (gz, xz, or bz2) is best for long term data archival at their highest compression?


I have a lot of tar and disk image backups, as well as raw photos, that I want to squeeze onto a hard drive for long term offline archival, but I want to make the most of the drive's capacity so I want to compress them at the highest ratio supported by standard tools. I've zeroed out the free space in my disk images so I can save the entire image while only having it take up as much space as there are actual files on them, and raw images in my experience can have their size reduced by a third or even half with max compression (and I would assume it's lossless since file level compression can regenerate the original file in its entirety?)

I've heard horror stories of compressed files being made completely unextractable by a single corrupted bit but I don't know how much a risk that still is in 2025, though since I plan to leave the hard drive unplugged for long periods, I want the best chance of recovery if something does go wrong.

I also want the files to be extractable with just the Linux/Unix standard binutils since this is my disaster recovery plan and I want to be able to work with it through a Linux live image without installing any extra packages when my server dies, hence I'm only looking at gz, xz, or bz2.

So out of the three, which is generally considered more stable and corruption resistant when the compression ratio is turned all the way up? Do any of them have the ability to recover from a bit flip or at the very least detect with certainty whether the data is corrupted or not when extracting? Additionally, should I be generating separate checksum files for the original data or do the compressed formats include checksumming themselves?

Upgrade from compression tools to backup tools. Look into using restic (a tool with dedup, compression and checksumming) on a filesystem which also checksums and compresses (btrfs/zfs) - that's probably most reasonable protection and space saving available. Between restic's checks and the filesystem you will know when a bit flips and that's when you replace the hardware (restoring from one of your other backups).

There are a lot of smart answers in here, but personally I wouldn't risk it by using a compressed archive. Disk space is cheap.


US ready to completely replace Russian gas and oil product supplies to Europe - Energy Minister


in reply to queermunist she/her

It's because they painted themselves into a corner by burning bridges with Russia. At this point, they're in a situation where they have hostile Russia on their border, and they lack a credible military of their own. This situation gives the US a huge amount of leverage over Europe.
in reply to ☆ Yσɠƚԋσʂ ☆

Their bridges with Russia can be rebuilt.

But even if that's a bridge too far, they could embrace Chinese solar and batteries and electrification. A large up front investment for the ability to generate their own power and cut fossil fuel dependency. China would happily work with them even if they still refuse reproachment with Russia.

Instead they're just idly waiting for the US to complete their colonization.

in reply to ☆ Yσɠƚԋσʂ ☆

I think you're mistaken here. Russia burned the bridges by invading a European sovereign country. This is not complicated.

It's incredible how people continue to peddle this infantile version of how the conflict started.
in reply to ☆ Yσɠƚԋσʂ ☆

Are you saying that Russia is not occupying parts of Ukraine? That the war would not end if Russia retracted their armies and left Ukraine alone?

Honestly, I don't even know why I'm trying to reason with a troll...

in reply to DreasNil

No, I'm saying that history didn't start on February of 2022. Here's a perspective from an actual adult with a fully developed brain

It's adorable that you consider what you're doing here to be reasoning.

in reply to ☆ Yσɠƚԋσʂ ☆

Thank you for this tip, I'll try to watch it when I get the time.

So you agree that Russia can end this war by pulling back their armies from Ukraine territory. That would be a first step for Russia to start mending the bridges that they burned with Europe.

in reply to DreasNil

This is a proxy war between Russia and NATO, where the west is cynically using Ukrainians to fight for them. This was admitted by no lesser person than the US secretary of state. Furthermore, Russia doesn't need Europe, they were able to redirect their economy towards the global south, and it's becoming clear that Europe's obsession with defeating Russia is self destructive. Europeans allowed themselves to be cut off from cheap energy from Russia and Chinese markets that underpinned European prosperity. At the same time, the US is now preying in weakened Europe forcing it into unequal trade deals and to buy its expensive LNG.
in reply to DreasNil

So you agree that Russia can end this war by pulling back their armies from Ukraine territory.


Ukraine could end the war by accepting Russia's demands. Or the US and Europe could stop arming and funding Ukraine, that would also end the war. That would be a first step to mending the bridges they burned with Russia by starting a proxy war.

Why would Russia surrender when they are winning? Makes no sense. Losers don't get to dictate terms to the winner in a war.

The terms for peace are well known. They had already been agreed to by both sides during the Istanbul negotiations in 2022 before the British and the Americans went to tell their proxy to abandon negotiations and fight to the last Ukrainian instead.

This what the war has been about all along. They could buy oil and gas from Southwest Asia and North Africa but they hate Arabs and Muslims even more than they hate Russians.

Tobacco companies aid vape shops in push to repeal Denver flavored tobacco ban, outraising law’s backers


A campaign group seeking to overturn Denver’s ban on flavored tobacco sales in the November election has far outraised supporters of the prohibition, campaign finance records show.

The opponents of the ban, a coalition of Denver vape store owners organized as a group called “Citizen Power!,” raised $410,000 through the end of August, according to campaign finance reports filed this month. The campaign group supporting the ban, “Denver Kids vs. Big Tobacco,” raised about $245,000.

In December, the Denver City Council near-unanimously approved a ban on sales of most flavored tobacco and nicotine products after public health and children’s advocates argued the products could lure young people into a life of addiction.

The council approved the ban, which applies to any sales within city limits, despite heavy lobbying from tobacco companies and vape stores. Mayor Mike Johnston signed it.

Nearly 2 million evacuated as deadly Typhoon Ragasa slams into southern China, after killing at least 17 in Taiwan


Nearly 2 million people in southern China were evacuated as a powerful typhoon hurtled into one of the world’s most densely populated coasts, having already unleashed deadly flooding in Taiwan.

Typhoon Ragasa, which a few days ago was the strongest storm on earth so far this year, brought finance hub Hong Kong and swathes of southern China to a standstill on Wednesday, after barreling through remote islands in the Philippines and mountainous regions of Taiwan.

Lawmakers and activists call for action after AP reveals US tech role in China's surveillance state


Lawmakers and activists across the political spectrum called on American tech firms to stop selling surveillance equipment to Chinese police and for Congress to examine the issue after The Associated Press reported that U.S. technology had played a far greater role than previously known in enabling human rights abuses by Beijing.

Republican Sen. Josh Hawley of Missouri told AP he wanted to summon tech companies before Congress to address how their technology exports were used. Hawley, a longtime critic of U.S. technology companies, bemoaned Silicon Valley’s general lack of cooperation with Congress on that and similar inquiries.

“I think eventually we’re going to have to subpoena these people,” Hawley said.

In a post on the social media site X this month, Hawley vowed that “Big Tech must cut ties with the CCP - or face my committee,” referring to the ruling Chinese Communist Party. Hawley sits on several Senate panels that might have jurisdiction to examine technology issues

An AP investigation published this month revealed that U.S. technology companies to a large degree designed and built China’s surveillance state. Firms including IBM, Dell, and Cisco sold billions in technology to Chinese police and government agencies, despite repeated warnings that such tools were being used to quash dissent, persecute religious sects and target minorities. Companies named in AP’s reporting said they complied with all export control laws.

Yang Caiying, who told AP for its investigation about how her family was targeted by Chinese surveillance using American technology because of their activism in rural Jiangsu, said she was “shocked by the pivotal role that major U.S. tech companies have played” in her family’s ordeal. Yang is now collecting signatures for petitions urging Washington to bar U.S. firms from selling to Chinese police, both online and on the street.

Other lawmakers from both parties urged Congress to beef up export laws to prevent more American technology from being used to fuel human rights abuses abroad.

“China has been utilizing partnerships with U.S. tech companies to build malignant ‘smart cities’ that are used for mass surveillance and human rights abuses against millions of innocent Chinese people,” said Rep. John Moolenaar, a Michigan Republican who chairs the House Select Committee on the Chinese Communist Party. The panel is charged with examining the strategic global competition between the U.S. and China.

“As executives at Nvidia and other American tech companies chase business in China, they cannot deny that their technology will be used to commit atrocities, strengthen China, and weaken America,” Moolenaar said.

Moolenaar called for American companies to work with Congress to write new laws that restrict the export of technologies that enable oppression. and work harder to keep their products from being smuggled into China.

Footage of deadly ICE shooting in Chicago suburb challenges official narrative


Police records and witness accounts from a Chicago suburb where a man was fatally shot by a federal immigration enforcement agent earlier this month complicate the picture of the event presented by the U.S. Department of Homeland Security, which said the agent fired his weapon after the man drove his vehicle toward agents.

Silverio Villegas Gonzalez, 38, was pulled over and eventually shot by a U.S. Immigration and Customs Enforcement agent in Franklin Park, Illinois on September 12, just after dropping off his two children at Passow Elementary School and Small World Learning Center, a daycare located blocks away from the incident.

Bodycam footage, which Reuters obtained on Tuesday, captures an interview with the truck driver, named in police records as Josue Hernandez-Rodriguez.

“He was trying to escape from them,” Hernandez-Rodriguez said.

In multiple statements, DHS has said the agent, who has not been identified, responded with lethal force because he was "fearing for his own life." But in bodycam footage, the agent, in a bullet-resistant police vest and torn jeans, described his injuries as “nothing major.”

The Fundraising-Industrial Complex Is Eating American Politics


In 2004, political campaigns spent 9 cents of every dollar raised on fundraising operations. By 2024, that number had reached 30 cents. American political campaigns are raising more and more money less and less efficiently. I’ve analyzed data from FEC disbursement records, using an algorithm I developed to classify expenditures by spending category. It reveals that campaigns are now spending 38 cents of every dollar raised just to raise more money—a fourfold increase from the 9 cents spent in 2004. In raw terms, campaigns burned through $3 billion on fundraising operations in 2024 alone.

This represents a fundamental shift in how political money flows through our democracy. Twenty years ago, fundraising operations were a necessary but modest expense, like renting office space or printing yard signs. Today, it has metastasized into the primary activity of most campaigns. In 2022, 31% of total expenditures were for fundraising expenses. This came close to exceeding the 33% of total expenditures going towards advertising. If current trends hold in 2026, it’s likely that fundraising costs will for the first time exceed what is spent on advertising, thus becoming the biggest spending category.




Portland threatens to evict Ice from Oregon facility over permit violations


The city office that oversees land use and zoning notified the owner of the building that Ice leases on 18 September that the federal agency had violated a conditional use permit approved in 2011. The permit limits the number of detainees Ice can hold at the facility each day to fewer than 15, and the duration for which they can be held, to less than 12 hours. The permit also bars the agency from “housing” anyone overnight.

But Ice data the city obtained via a Freedom of Information Act request, included in the official notice, shows 25 instances since January in which Ice held a person for more than 12 hours. On 26 January alone, agents held 16 people – listed as citizens of Venezuela, El Salvador, Honduras, Mexico and other countries – for over 27 hours before transferring them, according to public records obtained by Street Roots and the Guardian.

The city’s notice also said the building was illegally altered when exterior windows were boarded up without proper approval. An Ice spokesperson did not respond to a question asking when the wood was installed, but photos and video taken at protests and posted on social media show the boarded up windows first appeared around 16 June.

Georgia’s Medicaid Work Requirement Program Spent Twice as Much on Administrative Costs as on Health Care, GAO Says


Most of the tax dollars used to launch and implement the nation’s only Medicaid work requirement program have gone toward paying administrative costs rather than covering health care for Georgians, according to a new report by the Government Accountability Office, the nonpartisan agency that monitors federal programs and spending.

The government report examined administrative expenses for Georgia Pathways to Coverage, the state’s experiment with work requirements. It follows previous reporting by The Current and ProPublica showing that the program has cost federal and state taxpayers more than $86.9 million while enrolling a tiny fraction of those eligible for free health care.

The GAO analysis, which does not include all the Pathways administrative expenses detailed by the news outlets, shows that as of April the Georgia program had spent $54.2 million on administrative costs since 2021, compared to $26.1 million spent on health care costs. Nearly 90% of administrative expenditures came from the federal budget, the report concluded, meaning that Georgia’s experiment is being funded by taxpayers around the country. Federal spending will likely increase given that the Centers for Medicare and Medicaid Services has approved $6 million more in administrative costs not reflected in this report because it was published before the state submitted invoices.
