  • True, in this case trash-cli is the sane command though, it has a much different job than rm. One is remove forever no take backs, the other is more mark for deletion. It’s good to have both options imo. Theres a lot of low level interfaces that are dangerous, if they’re not the correct tool for the job then they don’t have to be used. Trying to make every low level tool safe for all users just leads to a lot of unintended consequences and inefficiencies. Kill or IP address del can be just as bad, but netplan try or similar also exist.


  • I understand that they were intending to unpack from / and they unpacked from /home/ instead. I’m just arguing that the unpack was already a potentially dangerous action, especially if it had the potential to overwrite any system file on the drive. It’s in the category of “don’t run stuff unless you are certain of what it will do”. For this reason it would make sense to have some way of checking it was correct before running it. Any rms to clean up files will need similar steps before running as well. Yes this is slower, but would argue deleting /etc by mistake and fixing it is slower still.

    I’m suggesting 3 things:

    • Confirm the contents of the tar
    • Confirm where you want to extract the contents
    • Have backups in case this goes wrong somehow

    Check the contents:

    • use "tar t’’ to print the contents before extracting, this lists all the files in the tar without extracting the contents. Read the output and check you are happy with it

    Confirm where:

    • run pwd first, or specify “-C ‘/output-place/’” during extraction, to prevent output to the wrong folder

    Have backups:

    • Assume this potentially dangerous process of extracting to /etc (you know this because you checked) may break some critical files there, so make sure this directory is properly backed up first, and check these backups are current.

    I’m not suggesting that everyone knows they should do this. But I’m saying that problems are only avoidable by being extra careful. And with experience people build a knowledge of what may be dangerous and how to prevent that danger. If pwd is /, be extra careful, typos here may have greater consequences. Always type the full path, always use tab completion and use “trash-cli” instead of rm would be ways to make rm safer.

    If you’re going to be overwriting system files as root, or deleting files without checking, I would argue that’s where the error happened. If they want to do this casually without checking first, they have to accept it may cause problems or loss of data.


  • Could make one archive intended to be unpacked from /etc/ and one archive that’s intended to be unpacked from /home/Alice/ , that way they wouldn’t need to be root for the user bit, and there would never be an etc directory to delete. And if they run tar test (t) and pwd first, they could check the intended actions were correct before running the full tar. Some tools can be dangerous, so the user should be aware, and have safety measures.


  • The biggest flaw with cars is when they crash. When I crash my car due to user error, because I made a small mistake, this proves that cars are dangerous. Some other vehicles like planes get around this by only allowing trusted users to do dangerous actions, why can’t cars be more like planes? /s

    Always backup important data, always have the ability to restore your backups. If rm doesn’t get it, ransomware or a bad/old drive will.

    A sysadmin deleting /bin is annoying, but it shouldn’t take them more than a few mins to get a fresh copy from a backup or a donor machine. Or to just be more careful instead.





  • I guess it’s more useful as a store of wealth than a currency. Like gold it can be transferred irreversibly between owners, except now the transfer and storage costs are significantly reduced and it’s available to the general public as an option. The key benefit is the use of the internet as a transfer medium, you no longer have to rely on a third party to facilitate the exchange, which for most large transactions means paying someone to transport it and store it (lawyers, guards, banks).

    It does allow for easy exchange for all users, including criminals, but generally using it for crime is a terrible idea, as every member of the network can see all transactions. Bitcoin is more of a notice board about what addresses have what amounts, and if you can prove to the people that post on the notice board that you control an address, you’re allowed to spend the contents and update everyone of where you sent it.

    People came up with an idea for how to do chargebacks, it’s called an escrow service, a third party that holds the money until all parties have had a chance to raise a dispute and confirm they are happy. This is the same as how PayPal works, trust based on reputation of the escrow provider, and the escrow provider is payed a fee. It’s just that now with bitcoin, you also have the option to complete the transaction online without an escrow provider, the same as you would in person with cash.


  • So it’s an app on Linux which you can get from github, and then an app on the Quest store. And it works by loading up the app on the Quest and streaming it all to there. Just AVR on the store, made by the same people as the GitHub. There’s guides online and it might be a bit fiddly if you’re not good with Linux. It still seems like a work in progress and you’ll need strong WiFi.










  • Just because you said medieval ruins, I’m much more impressed with the medieval buildings that aren’t ruins. Definitely worth looking into some of these less well know places if you ever plan a trip, or just want to look up some cool pictures.

    For US people, the thing thats most impressive, is that all of these were built before Christopher Columbus even started his voyage to the americas in 1492.

    Ye Olde Trip to Jerusalem, Nottingham - Established around 1189, makes it approximately 835 years old. The pub is partially built into the sandstone caves beneath Nottingham Castle. Still a great looking and fully functioning pub today, I want to go there.

    Anne Hathaways Cottage, Stratford-upon-Avon, Warwickshire - Dates back to about 1463, which makes it around 560 years old. A very British medieval farmhouse and the childhood home of William Shakespeare’s wife.

    Stokesay Castle, Shropshire - Was built in the late 13th century, around 1291, which makes it over 730 years old. It’s one of the best preserved fortified manor houses in England.

    Monnow Bridge, Monmouth, Wales - Was built in the late 13th century, around 1272-1297, making it about 725 years old. It’s the only remaining fortified river bridge in Britain with its gate tower intact.

    St. Ives Bridge, Cambridgeshire - Built in the 1400s, making it around 600 years old. The bridge has a full chapel in the middle.


  • Just to address the chatgpt comments, I assumed you were a troll but I now see that you’re a real person, deserving of a real answer. My standpoint is that science should enhance religion: as they approach different problems, they should be compatible. Science deals with the workings of the natural world and how things happen, while religion often addresses why the world exists and what our purpose might be. For this reason I’m against dismissing scientific discoveries solely due to religious teachings. Some see new discoveries about the universe as enhancing our understanding of God. Just because the bible was written without the understanding we have today doesn’t mean that the progress of all modern knowledge is false. And similarly when specific bible teachings are disproven doesn’t mean that the underlying purpose or values are invalid. In summary, ai think the purpose of religion is to improve society and wellbeing by addressing fears, providing a deep need for community and creating a moral code. I think problems and frictions arrive when, the moral codes develop over time due to new understanding of what is right or fair, and knowledge of the world improves. There are religions that accept that they should change over time and accept these new viewpoints, such as evolution, dinosaurs, or to respect womens rights. There are other hardline religions that believe that the world is 6000 years old, that women have no rights, that dinosaurs are false creatures created by the devil, and that technology is evil and should be avoided. Right now you seem to be leaning towards more hardline standpoints, which can anger some people, as you’ve seen by the down votes. I would encourage you moving forwards to not see new viewpoints and scientific understanding as a challenge to your religion, and instead accept that the world is beautiful and this knew knowledge was a gift to you from God. Gay marriage is legalised, so God accepts that people should be allowed to be happy in themselves, accept that into your religion. Dinosaurs are found and thousands of people work to understand them, God has given those people a gift to work in such an exciting career, accept the gift into your religion. To dismiss knowledge, is to dismiss a gift from God. Ancient wisdom and modern understanding should go hand in hand.


  • It sounds like you’re taking a skeptical stance towards the conventional interpretation of dinosaur fossils without proposing an alternative hypothesis for their origins. This approach can be useful for critically examining evidence but might limit understanding if alternative explanations aren’t explored. In scientific discourse, it’s typically valuable not only to critique existing theories but also to propose viable alternatives that can be tested and evaluated against the evidence. If the goal is to challenge established views like the existence of dinosaurs, developing a coherent alternative theory on the origin of fossils could strengthen your argument and provide a new perspective for consideration.
