    You don’t have to install drivers or CUPS on client devices. Linux and Android support IPP out of the box. Just make sure your CUPS on the server is multicasting to the LAN.

    You may need to install Avahi on the server if it’s not already (that’s what does the actual multicasting). The printer(s) should then auto magically appear in the print dialogs on apps on Linux clients and in the printer service on Android.

    On Linux it may take a few seconds to appear after you turn it on and may not appear when it’s off. On Android it shows up anyways as long as the CUPS server is on.




  • TBF in most cases forced app obsolescence is on the developers. Some of them are super aggressive and will force you to update without really needing it. Like, come on, package tracking app, I really don’t believe you’re unable to show me the package pick-up barcode without updating. 🙄

    But yeah, on iOS it’s completely impossible to get older versions, once you’ve updated something that’s it. And even on Android I’ve noticed that it’s become impossible to downgrade some apps even if I have the old apk, the Google installer simply fails to install it if I’ve ever had a newer version installed.


  • In the olden days software used to be sold by individual major versions. You paid for version 9, you paid for version 10. Or you skipped versions you didn’t need. You could use versions side by side. The newest installed would import its data from the older ones. etc.

    App stores have made this very awkward or almost impossible. There’s no concept of separating major versions. You’d have to buy and install completely different apps to be able to pay for them separately and to use them side by side, but if they’re separate apps they can’t import your data from each other. Not to mention that people seem to hate having “too many apps” for some reason.

    Software subscriptions switch the “support per major version” to “support per time of use”. It’s obviously shittier but it’s more realistic than a one-time price and expecting to use the app in all future versions in perpetuity. The one time price would have to be very large to be realistic.


  • It’s impossible to tell how meaningful Backblaze’s numbers are because we don’t know the global failure rate for each model they test, so we can’t calculate the statistical significance. Also there are other factors involved like the age of the drives and the type of workload they were used for.

    buying more reliable devices can definitely save you time and headache in the future by having to deal with failures less frequently.

    That’s a recipe for sorrow. Don’t waste time on “reliability” research, just plan for failure. All HDDs fail. Assume they will and backup or replicate your data.



  • For home setup you don’t care because you should have either redundancy or backup (preferably both).

    So that typically means buying the cheapest HDD that’s new and from one of the established brands (Seagate, Western Digital, Toshiba) that’s in the correct size for your needs, and you can afford to buy it at least twice (for the aforementioned backups or redundancy), or even thrice, and replace as soon as needed.

    In other words there’s no need to speculate on how long an HDD will last, you simply replace it when needed.

    Please also note that HDDs over 10 TB are starting to get increasingly replaced with enterprise models which run hotter and make more noise.





  • Everybody should be using DNS over HTTPS (DoH) or over TLS (DoT) nowadays. Clear DNS is way too easy to subvert and even when it’s not being tampered with most ISP snoop on it to compile statistics about what their customers visit.

    DoH and DoT aren’t a full-proof solution though. HTTPS connections still leak domain names when the target server doesn’t use Encrypted Hello (ECH) and you need to be using DoH for ECH to work.

    Even if all that is in place, a determined ISP, workplace or state actor can identify DoH/DoT servers and compile block lists, perform deep packet inspection to detect such connections regardless of server, or set up their own honey trap servers.

    There’s also the negative side of DoH/DoT, when appliances and IoT devices on your network use it to bypass your control over your LAN.




  • Then why do they offer a separate, distinct DDoS mitigation feature on the enterprise plans? And did you notice they call them “mitigation” and not “protection”? 🙂

    Look at the description of each one, the free one “stops illegitimate traffic at the edge”. Meaning they’ll serve from cache, it’s not getting through to your actual site. You can get caching from any CDN service, it doesn’t have to be CF. All CDN services are distributed and will try to serve for as long as possible because their whole purpose is to deal with traffic spikes.

    And if you want to know for how long CF (or any service) will serve from cache and how far they’ll go for an account (especially a free account), you want to check the terms of service not the plans. The plans are made to sell to you, the fine print is in the terms.

    Anyway, I really don’t understand people’s obsession with DDoS, particularly self-hosting people. The chances of their little website ever being the target of a DDoS are astronomical. Many of them don’t take proper backups, and don’t worry about theft or fire or electric spikes, which are far more likely, but go frantic when they hear about features they’ll never use.






  • You don’t have to worry about DDoS:

    • DDoS is an advanced technique and the people who can do that spend a lot of time and effort putting malware on machines that can be ordered to perform DDoS on command. They usually sell that attack capability and it ends up getting used against worthy targets, we’re talking attacks that disrupt entire industries, elections, warfare etc. Do you really think what you’ll be hosting will attract that kind of attention and be impossible to take down with simpler methods?
    • To survive a DDoS attack you need a lot of resources, from a professional platform (like CloudFlare). The stuff they offer for free is not going to get you through a DDoS. If you’ll read their terms you’ll see it’s worded just ambiguously enough to mean nothing. If you ever actually get targeted by an actual DDoS and you haven’t paid a lot of money to a platform like that, everybody will simply drop you instantly (your ISP, your VPS provider, your tunnel provider, your VPN provider etc.) and possibly kick you off their service too.

    If the stuff you’ll be hosting is static files you can use a CDN service. CDN’s are designed to be distributed and redundant so they’re somewhat resilient to DoS attacks by default. They’ll still kick you off if it gets to be too much but maybe you can weather shorter/moderate attacks.

    If you’re hosting a dynamic/interactive service forget about it.
