I think it would allow for more specific conversation if there was a way to post something in a way that it only appears to people following the tag you post it to, and not to people following you.
A good example would be very technical discussion of hobbies, which I think Hubski would benefit greatly from, but only seems to happen deep inside of comments of unrelated posts.
Say I posted a question about Archery and wanted to know whether I should buy a compound or recurve bow, or even more technical I wanted to know whether I should use orthographic or perspective projection, or should I use GL_ModelView?(Actually something I'm confused about now if anyone has experience with Open GL), people won't want that sort of thing on their feed so I don't ask. But if there were a way just to post it to the programming tag I wouldn't have to worry about my follower's feed. Plus people might be more likely to follow tags this way.
I feel like following people rather than (or in addition to) tags is one of Hubski's defining features. Seeing everything that an interesting person is interested in, rather than one's own narrow set of interests. It broadens one's worldview a bit, as it were. People can always follow you and filter yourname.archery if they notice half your posts are interesting, and half are technical archery stuff they don't care about.
You're right, you've changed my view. I think it'd would be helpful in some rare cases but it wouldn't be worth adding the complexity to Hubski.
(No offense Complexity :-) )
With regard to the OpenGL question: In an orthographic projection, objects of different distances appear the same size. Which is unnatural. Objects farther away appear smaller in reality. You usually want perspective projection. OpenGL has a series of matrices, which are applied in order when it draws. The default initial matrix is GL_MODELVIEW, which is typically what you operate in and apply your transformations to move around your objects and things. The GL_PROJECTION matrix is used to change the projection of the entire scene. For example, when the window is resized, you typically want to switch to the Projection matrix, call gluPerspective() with the new window coordinates, and then switch back to the ModelView Matrix. Does that clear things up? I just happen to have taken a Graphics class last semester. :)
On the original topic, if these are the little slices of information that could be accused of clogging up my feed, I'm A-ok with it, cause I just learned a thing.
Thank you! very helpful. I'll be using ModelView. The plan is to translate every set of triangles contained in an Entity object to their x, y and z minus the camera's x, y and z, rotated to account for camera angle using cos, sin and tan magic with the Entity's rotation added on. Should that work?
Sounds good to me. You shouldn't need to use trig functions manually, though. OpenGL has translate and rotate functions. Typically the way you draw an object is to push a matrix, apply the translations and rotations to where you want the object to be, draw the triangles and textures, and then pop the matrix, so you're back at the origin ready to draw the next object. So, OpenGL takes care of all the linear algebra and trig for you.
Here's another point to add to the comments already on your question: I don't follow the tag #archery but I know people who are into archery and would have an answer on the archery question. mk, further to my earlier suggestion that thenewgreen liked: if there were an "invite" link at the top, with one click, I could invite my friend to answer the archery question. The invite email could take him right to the page where the archery question was asked. for the to-do list, sometime in the future. . .
I encountered this problem in instances like when asking about an MPC-type controller thingy in #music. I settled for beginning my title with "[help!]" to imply that I'm not sharing content so much as making an inquiry, so people who may be knowledgeable on the subject would be attracted to click, instead of someone digging for news. Your idea would have come in handy in that scenario, but on second thought I say screw it, why should I hide that anyway, because someone may eventually stumble upon that post in a feed and be more interested in that inquiry than on the latest from Pitchfork. At worst, one could ignore your .personal tag I guess. And that would suck. It leaves me curious though, idk.
