    IMO, if you are printing PLA, it’s not worth it.

    The usefulness increases with the temperature. It dramatically reduced my printer’s consumption when the bed is 95°C, and allowed it to heat up to 115°C without pushing it to its limit (I didn’t try anything further).

    I have an adhesive insulator from Aliexpress. It has lasted for a few months without any visible wear, but I can’t say much about its longevity. But given the price, I would be kinda ok with it lasting only a couple of years.











  • It’s to be expected that the author blocks anything that can refer to keyword blocking. But “perchance” is as random as the movies community.

    The json is also full of inconsistent formatting, what probably means it was all written by hand. The author put a lot of caring into disallowing communication in his communication software.


  • So… 560 users banned by name (I can’t believe I made into the list!), 2200 username regexes (I wonder how many false positives there are), 98 communities banned by name (a lot of non-radical politics, but stuff like “movies” made into the list too), 33 community regexes (it would be a nice game to make false positives of “^Fuck.*US”), 54 instances, 354 domains, and a “clbuttic” filter with 296 forbiden content regexes.

    Does the application actually show any content?






  • processing extreme amounts of data at extreme io rates

    For anybody trying to take that seriously, keep in mind that the Oracle’s query planner is absolutely shit, the write performance can go to shit depending on the contents of your transactions, any advanced transaction insulation also destroys performance, and single-machine performance is completely shit, the extreme numbers are all on scalability and when compared to other (unpatched on the case of Postgres) ACID databases.

    Also, it’s not clear if those claims are still real, because you can only run Oracle databases if you sign a contract saying you won’t compare it to other systems.
