Not sure why you need individual Apple IDs? I use one to install core software for people.

We just use local users, but their server software is cheap and easy to set up network users.

We didn't use local users, and they had to be able to work through the Windows network. I had it explained to me as, "it's the only way to get them hooked into the windows environment." I don't know that it was the case but since I wasn't the netadmin I didn't see the need to question it.

Given you're talking about running Apple server software for network users, I suppose they were correct.

For those of you who want to know about what wi-fi routers to buy etc, this article is great at explaining how wi-fi works and what the numbers you see on devices don't mean.

I have always used the rule of thumb that total bandwidth on wifi is half of whatever the lowest connection rate on the network was, divided between all systems on the network. My fastest connection is 650mbps (ac for the laptop), and 40MB/second is the fastest I have ever seen from it in actual transfers (reading from the NAS onto the laptops SSD, going the other way I am limited to 20MB/sec writes for the cheap WD Green drives). I have separate networks for B/G, N, and AC, and get the results I expect for the "50% of nominal" rule of thumb.

Main thing seems to be having different Tx/Rx sets on the router for each network (edit: And different networks for each type), so the slow systems don't bottleneck the fast ones.

So now that Dropbox has now fully fucked my 5-yr old blog by disabling links to all the pics on it....

What are people using for Dropbox replacements for image hosting? I don't want to do imgur or whatever, I like the privacy and control of Dropbox, the pseudo-ftp server feel of it. Time to bite the bullet and get my own hosting or is there another good option out there?

Also, fuck Dropbox right in their shitty whimholes. "Oh, we decided you don't work this way, so now you can't." I know they gave a few months lead-in that it was coming, but I'm not going to go back and edit 5 years worth of sometimes daily art posts. Not to mention several forums I've linked images to.

1. I don't know of a decent replacement for Dropbox Public folder, but then I haven't looked very hard.  I'd like to find one.

2. Yes, fuck Dropbox.  I only keep things in there now because: a) free, b) lazy

2.a Might start putting things in my IBM Box account (unlimited storage) but the problem is that I don't know how long I'll be working here.
2.b There should exist a pre-made front end for a S3 static HTML site which enumerates all the objects... unless that isn't "static".  I'm not a web programmer.

3. Don't edit, use sed or one of the hipster editors like Atom (atom.io).  Atom will do search+replace on all files in a dir tree.

Bit the bullet and bought some hosting. I think I'll try to move my entire site (including broken image links) over, just to have the historical text intact.

Couldn't bring myself to consider any solutions that were subject to whim again. Working with a lot of Google products has made my tolerance for changing fundamental shit 'just cuz' entirely nonexistent.

I don't know that fancy talk, I'm just a potato farmer. Sounds like what I want, but eh.

Why do I think Adaptive geometry/ model degredation is a thing in game engines? Have I made that up in my head?

i.e. load fewer polys the farther from the camera you are.

Nope it's been a thing for a while now. I still remember there was an article in a gaming magazine like CGW talking about that technology being used in the original concept of TF2 (a military shooter, not the cartoony thing it became).

Poly-count LOD has been in game engines forever. It was already old hat in the graphics research world 25 years ago, and I remember games for the Voodoo2 that had it. If done poorly, it's really obvious especially in terrain--distant mountains will change shape as you get closer, trees (and people!) can lose limbs, cars become boxes, etc.

The ROAM algorithm (for real-time optimally adapting meshes) (ACM digital library citation) was first published in 1997. A decade later, there were already papers about use of modified ROAM in game engines. I worked on a large-scale visual simulation systems before (1993+) then that had adaptive model degradation for distant models and terrain, but it was computed statically because of customer requirements on model fidelity.

Yeah that's what I thought. So clearly the people in my software dev group using Unity, Unreal and Stingray for AR/ VR have no idea how the fuck to utilize this.  The complaint with the hololens on a call today was they had to manually downgrade everything in maya to make some models work and not stutter.

Which meant loss of fidelity for the overall project meaning AR "wasn't yet viable" for things like demoing how something comes apart if you're loooing at a complex object or machine.

That's how I've always used dropbox. How were you guys using it and what did they get rid of?

They used to have a Public folder that let you embed images on forums. So if any of the images in my older posts have disappeared, it's because they removed that feature.

Heh.  The State Department blocks everything about dropbox on our network (even going to their website).  So all I saw was a series of X's when ever you assholes linked pictures from your dropbox to here while browsing at work.  I welcome this change!   awesome, for real

Yeah, no more free image hosting. We can give a link but it requires a click-through to their cookie-laden ad-frame viewer.

Not really, no. Any gripes are purely selfish on my part and I realize that. If I want to host images I can use a paid service, it's just *effort* vs "eh I'm already using this site for files..."

Yep, I completely understand why they did it. And bitching about losing 6 years of free hosting is  why so serious? Especially as they gave us plenty of notification it was happening...

I've only use imgur for temporary stuff, don't know how their ui is for more robust image hosting options.

I went with my own hosting because then I can just set it up with my own url and if I change hosts it won't break everything.

Imgur seems fine for me for simple stuff, if you create an account you can have as many separate albums as you want, you can make your images private, upload is fast and simple, you can link directly to images, etc. The only time it shits the bed a bit is when Reddit USA all come online at once in the evening and it gets a bit overloaded.

Unrelated, but can anyone recommend a lightweight & free program for drawing simple things like flowcharts etc.? Something like PowePoint or Visio but much, much simpler. I want boxes, lines, text, maybe a snappable grid, not much more. It needs to run on a low end windows PC (Surface Pro 3). I tried LibreOffice but it was slow as fuck. It's only got 4Gb of RAM and Windows 10 eats half of that.

I recently found Pencil for UI mock-ups, it's got a flowchart piece to it. It's pretty simple and easy to use as well as free. My biggest complaint is that it doesn't seem to keep the layers/ draw order correct when I open old files.

http://pencil.evolus.vn/

Fake Edit: Just went to the site and there's a new version. I had 2.x which was where I had the problem. No idea what 3.0 is like

Real edit: Also, you could try SnagIt by Techsmith. It's meant to be a screenshot markup program, but you could use it for flowcharts if so desired. Pencil would be my first choice, though.

Have you saved, closed and then reopened your file yet? That's where all the surprises happened.  I opened one of my 2.x files and it's fucked, but I haven't corrected it to see if 3.0 fixed things.
