  • This. Some people don’t realise how ridiculously easy it is to change a lock when you can open the door with a key.

    1. Put the working key into the lock

    2. Undo this screw

    1. Turn the key slightly back and forth whilst pulling the cylinder out until it starts to come out. Then just pull it all out.

    2. Mark which side was front and back

    3. Measure from the middle locking mechanism of the cylinder to the ends.

    4. Find a lock with the same lengths. It’ll be like 60/40 (100mm total length).

    6b. Optional: get one with a fixed turnkey on the inside.

    1. Replace lock by reverse.

  • I hear you. I worked for an msp where some customers would refuse to invest in backup solutions and we either declined to renew their contract or they suffered an event and we were then setting up backups.

    I was in the middle of a migration from OVH to Hetzner. I knew I had good backups at home so the plan was to blow away OVH and restore from backup to Hetzner. This was the mistake.

    Mid migration I get an alert from the raid system that a drive has failed and had been marked as offline. I had a spare disk ready, as I planned for this type of event. So I swapped the disk. Mistake number 2.

    I pulled the wrong disk. The Adaptec card shit a brick, kicked the whole array out. Couldn’t bring it back together. I was too poor to afford recovery. This was my lesson.

    Now I only use ZFS or MDRAID, and have multiple copies of data at all times.


  • I’m lucky enough to run a business that needs a datacenter presence. So most my home-lab (including Lemmy) is actually hosted on a Dell PowerEdge R740xd in the DC. I can then use the small rack I have at home as off-site backups and some local services.

    I treat the entirety of /var/lib/docker as expendable. When creating containers, I make sure any persistent data is mounted from a directory made just to host the persistent data. It means docker compose down --rmi all --volumes isn’t destructive.

    When a container needs a database, I make sure to add an extra read-only user. And all databases have their container and persistent volume directory named so scripts can identify them.

    The backup strategy is then to backup all non-database persistent directories and dump all SQL databases, including permissions and user accounts. This gets run 4 times a day and the backup target is an NFS share elsewhere.

    This is on top of daily backuppc backups of critical folders, automated Proxmox snapshots for docker hosts every 20 minutes, daily VM backups via Proxmox Backup Server and replication to another PBS at home.

    I also try and use S3 where possible (seafile and lemmy are the 2 main uses) which is hosted in a container on a Synology RS2423RP+. Synology HyperBackup then performs a backup overnight to the Synology RS822+ I have at home.

    Years ago I fucked up, didn’t have backups, and lost all the photos of my sons early years. Backups are super important.




  • The entire article seems like an attack. The author finds a unique identifier and adds “Russia bad” throughout.

    States the information is in cleartext but then explains how everything is encrypted (in transit).

    What will the author do if they intercepted any single online stores transfer of credit card details. Also encrypted in transit but Is that also deemed as cleartext? Or is that okay?

    I don’t think much new is learnt here. WhatsApp also sends metadata in “cleartext” (not really, as it’s encrypted in transit, but this article called that “cleartext”).






  • I note that you reported this post as “wild misinfomation”. Now I’m totally ignorant on the topic, so can you elaborate some more on how this is ECT?

    On face value, the Wikipedia article you posted describes ECT’s purpose is to induce a seizure.

    Electroconvulsive therapy (ECT) is a psychiatric treatment that causes a generalized seizure by passing electrical current through the brain

    The article mentions something much milder

    by wearing a small device that applies mild electrical micro impulses

    ECT sounds horrific, but without further information, the articles only similarity is “electric meets brain”, but without the seizure part.








  • I don’t think this technology is intended to be used for global internet. But for giving access to a remote town, this is many magnitudes lesser in cost than a satellite.

    A brief internet search tells me that a Starlink satellite is ~$1 million apiece, and lasts 5 years. With the additional cost of the launch the annual cost is ~$300,000 per year per satellite. You can work out the cost for 10 masts and tell me that its much cheaper.

    From a consumer perspective, Starlink is amazing. Fast, relatively cheap, available anywhere. From a labour and material cost, its incredibly expensive. If a town can be serviced by cable, wireless, this new laser or whatever then the economical and environmental impact (in terms of materials) are a fraction.

    Whilst masts will face the same prejudice as windmills for destroying landscapes, Starlink has already been causing issues with stargazing and night sky pollution. And this is only the first commercial venture for low-orbit internet. I can imagine there shall eventually be multiple of these setups, each with thousands of satellites (Starlink is at 7k+ now I think) which will only exacerbate the issues.

    The point being, that having other technologies with overlapping abilities isn’t a bad thing. Choice is good.
