Lexical Unit posted:Oh cool, something that isn't what I was talking about. Having a mega list that's comprised of several smaller lists isn't really that useful, you'd have to switch between each list continuously to make sure you got the right amounts and didn't miss anything. For example, if an item appeared on multiple different lists in different amounts, you'd have to be careful to check every list to know you got the right amount of it. Certainly possible, but not ideal. I'm not the author of that app, but I'd go out on a limb and say that's what the "Entire Grocery List" button does. If it doesn't, though, you're right that functionality should be there.

That said, it is true that I don't consolidate similar ingredients from different recipes, so "sliced turkey breast" and "turkey breast, sliced" will show up as two separate line items. I've been thinking of solutions for this but nothing comes to mind that doesn't involve 1) a crazy amount of string parsing in Objective-C or 2) imposing a bunch of structure on the format of the ingredients. (1) isn't really my idea of a good time and seems like it would be prone to failure while (2) isn't terribly feasible since I'm offering the ability to pull recipes from the internet, whose ingredients could be written in all sorts of different ways. That said, I do think it is a good idea, and might take a crack at implementing it in the future if I can do it well. For now, I'm offering the workaround of being able to edit the grocery list once you've added recipes to it, so you can delete the duplicated entries if you'd like. Oh, and since the original screens were posted, I've added the ability to select between 'All', 'Purchased', and 'Unpurchased' items in the grocery list. In actual usage, filtering by 'Unpurchased' and then checking items off as I go seems to work reasonably okay. See screenshot below (click for big):

I don't know if it's something you'd want to consider but TaskList has a neat little system for this kind of thing. Each task can have an author, assigner, category, etc. At any point in the task creation process you can type in whatever you'd like or choose from anything you've ever typed in before by checking a checkbox on it. This would probably limit your ingredient entering interface in a couple ways though, since you'd either need individual textbox/dropdown lists on ingredient entry (essentially breaking c+p) or do a post ingredient entry parse of a text list (complexifying the entry process).

My current project is a browser-based interface for a small database that's used by some public organizations in my state. Right now the plan is to have it be local network/VPN access only, but that may change. It runs on top of a very stripped down install of Joomla!, mainly to make use of the nifty Fabrik extension, which handles all the tables and form views. If you're doing database front-end stuff in a browser and you're willing to put up with Joomla! it's worth checking out, it's designed to be a no-coding-knowledge-necessary extension for making forms/tables, but it's very developer friendly (you can write your own templates for table and form views, pretty much everything from the forms to the individual input elements make use of plugins so if you're familiar with Joomla! MVC style you can write your own, the extension provides places where you can stick PHP and javascript and specify when/where it runs, among other things). I'm using Mocha UI's virtual desktop for the interface. Because of the nature of the project, I have the luxury of telling my clients what browser to use (leaning towards chrome over mozilla prism at this point, firefox simply doesn't handle mochaUIs effects very well, and seems to be the worse of the two as far as keeping memory useage reasonable) Not really sure about this theme, since I think they're expecting a fairly spartan app, but that's probably a good thing because design isn't my forte:  Click here for the full 936x559 image. The uninspired vanilla theme with some open windows showing a table and a form view:  Click here for the full 936x558 image. Orbis Tertius fucked around with this message at 10:28 on Sep 17, 2010 |

I have nothing to show off from Pulse but it's pretty much exactly the type of thing I love. I search for flash games like this some days and there's only a few out there. This would be pretty much suited to a game too if you had some levels, some pre-placed pieces, and limited amount of certain pieces for that level which you had to use to fulfill a goal or something.

 Been working on my raytracer a bit more. The rendered scene consists of around a 105,000 triangles with 2 bounces for reflections. Without supersampling it took about 16 seconds to render at 1280x800 and with 4x supersampling you can multiply that by 4. So it's really not all that fast, but it's just a hobby for me so I'm pretty satisfied with it. I wrote a bounding volume hierarchy that encloses all the triangles in a AABB tree, which really makes all the difference when you want to start rendering meshes. Without some sort of acceleration structure (BVH, KD tree etc) it's really, really painful to render anything over a thousand triangles. If anyone cares, the BVH took about 700 ms to build. I should probably write a neat little GUI with QT to make it easier to create scenes and modify rendering variables but I've been pretty burnt out due to university work. I'm probably gonna implement something not-as-critical like raycasting based ambient occlusion (which means reading about Monte Carlo methods which I'm not familiar with) before I get around to making the actually useful GUI or multihreading the trace algorithm because that's how I roll

In the actual wallpaper it stops for a couple of seconds before flicking to blank, but it's not a bad idea to give it a nice transition. Either fade it out, or solve the maze or something

A simple 4-rays-per-packet packet tracer will give you a ~3.5X performance boost. Sometimes it goes superlinear due to cache coherence Consider using 64 bit for the 8 extra SIMD registers. How are you choosing the splitting plane for the BVH? (btw, seriously consider going kD-tree for static scenes, especially with the sort of scenes you're using Also, the tree nodes can get *much* smaller.). If you use the SAH or SIROH when building the tree you can get up to a 2X speed in rendering performance over median splits. Of course, the builder becomes a *lot* more complicated unless you want to sort the primitives at each build step. quote:multihreading the trace algorithm because that's how I roll Tiling the screen into 32*32 pixel tiles seems to be the sweet spot for most people. To avoid the locking of the job queue, use a single int which represents the job number (an index into the tiles) and use atomic operations to fetch the next job. Other cheap speedups come from pre-calculating some of the triangle intersection code offline. For my code I get about 15% faster using TriAccels Sorry if you know all this, I just like talking about RTRT There's lots of other neat tricks like large packet tracing with frustum culling, entry point search techniques (MLRTA and AEPSA) that you can seriously make a difference. My first render of Sponza took 2 hours. These days, I can walk around it at 200fps on a CPU (2 x 2.0GHz Xeons)

Zakalwe posted:Awesome advice about speedups. Great advice, thanks. I'm not really that well versed in ray tracing or computer graphics for that matter and this is actually my first raytracer, so all advice is welcome. I'm not really aiming for real time performance, but speed is always nice. Packet tracing is basically based on utilizing SSE calculations for ray packet intersections and traversals, right? I have never done anything with SSE so implementing all that might be a bit too hard for me, but I might look into it after I've actually got a decent non-RT raytracer working. Any good papers/sites about SSE in packet tracing or just SSE in vector calculations in general? As you seem to have guessed, I'm using a naive median split as my construction heuristic. I've only glanced at other heuristics but SAH seems to be the most popular choice and I'm most likely going to implement it when I have the chance to actually study it. Thanks for the thread advice is well. Threads and SAH (or some other heuristic other than the median split) are probably the two things I'm gonna implement as soon as I have the time. Packet tracing is probably going to have wait for a while or a really, really long while. Converting my calculations to SSE might be a bit painful as I have no SSE skills

Yup, it goes to a dumb frame-buffer and blitted over via SDL. 32bit 512x512 with textures. I can go much faster in other scenes, dpending on the view point.

Any good papers/sites about SSE in packet tracing or just SSE in vector calculations in general? simple 2x2 (4 rays per packet) packet tracing is just tracing 4 rays at once through your acceleration data structure and intersecting 4 at once per triangle at each leaf via SSE. Large packet tracing involves more than that (frustum culling etc). GCC has great support for SSE intrinsics in that they are treated as a basic type for the most part with operators +-=*/ etc defined for them. This makes code a lot more readable. A lot of the demo code you might see will use intrinsics though. Carsten Bentin's thesis is *very* good for implementation detail. It's a bit out of date in one or two places, but you won't hit those until you go much deeper. http://graphics.cs.uni-sb.de/~benthin/phd.pdf quote:As you seem to have guessed, I'm using a naive median split as my construction heuristic. I've only glanced at other heuristics but SAH seems to be the most popular choice and I'm most likely going to implement it when I have the chance to actually study it. SAH is a good choice but we (a colleague and I) are trying to get people to try SIROH as it edges ahead a bit (a whopping 4%!).

Some of them could look more interesting than your recursive backtracker. There's a good list here. Raise the price. No, seriously. Multiple developers have observed that app price under a certain point (around $5) seems to have no effect on sales-- the most important barrier is that of the user deciding to actually buy it, not the numeric cost. You'll get the same number of sales at £2 that you'll get at £0.75, but more than twice the revenue.

I know I personally have another category in my head that has a break somewhere around $1.19. I definitely think when looking at some prices of "that's cool and it's less than a buck I guess I'll get it" vs "That might be ok, but I'm not sure if it's worth a buck fifty". I would agree at from about $1.50 to $4.50 I treat the apps around the same though as in if it looks interesting I'm willing to try it and return it in under 24 hours if I don't like it. At $5 or more it would have to be something amazing I'd use all the time with no alternatives for me to buy it and even then I've skipped out on some apps.
