  • It’s also important to note that you might come out ahead in learning those abstract concepts using a harder language.

    But my first language was Pascal. from a book stolen from my dad’s library. Then C++. I still wouldn’t call myself anything other than an amateur… I mean, my dad can do more with one line of C than most programmers can do in their entire career. (he really shouldn’t. but he does. Calls it “job security”.)




  • yes. I don’t generally add the alt-text option (that’s more for hyperlinks. it doesn’t show on image links). !.

    Most websites will let you right click and image and copy the image’s URL, alternatively, you can open that image in a new tab (just the image,) and then copy that URL, and it’ll display the picture. Lemmy will host an image if you’re adding it from your computer. (for that use the ‘upload image’ tool in the editor buttons.

    edit, Relevant XKCD:

    Use this power responsibly… or not. this should fun.






  • I promise… it’s just enthusiasm!

    even the linux-from-scratch snobs are usually pretty decent (really it’s only when it’s their first time out of the server room in too-long a time). I usually try to switch it up to something like "have you tried playing The Battle for Wesnoth. (it’s a turn based fantasy strategy game that’s… uhm. surprisingly good.)

    You could always put them in a co-orbit with earth or something and then just use solar sails to provide the delta-v

    But I also like the idea of certain peeps having time to understand the error of their ways before slowly falling into the sun faster and faster.

    And before some one says “well, there’s still plenty of time for that with a rocket…”

    Naw. We’re talking about a truly idiotic person. It’s gonna take them a while,




  • Mostly by the cost? As for sets, they’re going to be 200+ easy.

    Theres also some difference in tolerances, but to be honest, a super tight tolerance is a double edged sword. Bulk-produced bolts won’t be as tight anyhow.

    For casual/infrequent uses, it’s totally fine to get the inexpensive ones. (I’d recommend going to a local hardware store, they tend to have not totally-shitty sets and most sizes/threads individually.)

    Also, for printed parts, you can absolutely just cut in with the bolt, unless your printer is somewhat inconsistent, a with a well-calibrated printer, all you really need to know is how much your holes tend to shrink (the thermal contraction as the plastic causes the final diameter to be smaller. This is why we invented test prints…… well. Not me. Somebody’s smarter than me.)


  • So the stuff about the 1/8” rod is… just a general fabrication tip.

    If you’re ever reading a bill of materials and they call for threaded rod- which is unfortunately common for a lot of printer groups- you can almost always use the same size smooth rod if you cut thread on the ends with a die.

    It saves money (threaded rod is smooth rod with threads cut the full length,) and it looks neater. (A drill and some sand paper and a bit of scrapped t-shirt cloth doped with green buffing compound will make it shiny, even.)

    What the other person is saying about tap magic, is just to use lubricants while cutting. 3-in-1’s og is my go to. Tap magic is a similar brand. You can get by with wd-40 if you have to.

    all it’s doing is helping with temperature, and making cleaner cuts since it lubes every thing (the cutting edge still bites, but it doesn’t bind as much with the chips.)

    The other thing to remember is that every turn or half turn, you should break off the chips (the metal coming off,) by backing off a quarter turn. This helps keep the cutting head free making a neater thread.

    Other than that there’s no reason to be intimidated by any of this. For this, you can probably just cut the m5 thread, but you’ll want to predrill what ever bolt’s standard bore size is, and be sure to keep that square and straight as you do.

    The uxcell is a “cheap” brand, for a one-time thing it’s fine but if you find you use it more and it’s getting frustrating to use… it’s lost its edge and is dull.


  • So, the biggest difference in quality is the steel and hardness.

    For 2020 aluminum, it’s not that big of a deal. Even less so for “occasional” use. For harder metals, the cheapos will wear out faster and that maybe leads to frustration.

    Guess my point was… we almost never use more than 2-3 in a set, so, it’s better to get the 2-3 and better quality at the same - but totally get the cheapie if you don’t want to spend that much.

    At least I only use m3,5 and 1/8” sets.

    Also, for the record, you can absolutely tap plastic for a reasonably strong thread. Just add a couple extra perimeters.
