https://free-visit.net : Like Matterport but with an FPS game engine. I am looking for my first client: Ideally someone in charge of a Museum/gallery or other grandiose indoor space.

Agree with another commenter about camera height. Couple more things. 1. Your demo level suffers from Z-fighting in a few places on the floors and walls. https://en.wikipedia.org/wiki/Z-fighting 2. When viewed full-screen on a 4k monitor, textures are too low resolution. A handwritten note on the wall is unreadable. 3. Lighting is too simple. Because that’s not an FPS shooter you probably don’t need dynamic lightning…

1: yes, improving it.

2: yes but it is a tradeoff between texture quality and minimazing loading time.

3: Yea, ideally. But KISS is my priority : We have an editor that aims to be simple enough for all, thus no BPR & no shader.

Problem: Create image with text. Solution: https://img.bruzu.com?a.t=Text You can help by trying the API and giving honest feedback. https://bruzu.com

The API docs' example URLs can't be copied and pasted, as "%20" gets inserted. I'm probably not the target audience for the API, but it's a neat idea. I think people will end up with images described with tons of magic numbers that relate to each other in invisible ways and become unmodifiable and unmaintainable. Variables might help, as might relative positioning and sizing of elements. Some feedback on the Designer…

Thanks a lot for taking time to trying it.

Fixed most of it.

Seems like it would be a lot easier and a lot more powerful to use SVG instead of a giant string of URL parameters. Your service could provide pre-made templates and an editor, and expose textfields, images, fonts, etc options via URL parameters. Then your service just has to render the SVG and return it as an image with the requested dimensions/format. Example: ` https://img.bruzu.com?s= ID>&title=Hello&font=arial&w…

Thanks, yes template is in future plans, will think about svgs.

I want to bring back old school distributed forum communities but modernise them in a way that respects attention and isn’t a notification factory. Mastodon is a pretty inspirational project but the Twitter influence shows, I miss the long form writing that was encouraged before our attention spans were eroded. Not at all close to solving it, but it’s been on my mind for a long time. Would love to hear if there are o…

I'm very interested in this space too. I want to start a project that explores different ways to communicate on the web. The current state of Facebook and Twitter are not the best way in my opinion.

You may be interested in my open source forum:

https://github.com/ferg1e/peaches-n-stink

It's basically an experimental communication platform. Right now I am building Internet forum style communication but I want to expand to other communication mechanisms later.

This might be a good use-case for the "bayesian truth serum" http://economics.mit.edu/files/1966 This applies when our questions are not just trying to learn about the world (e.g. 'Our survey discovered that 10% of posts are considered misleading'); we are going to use their answers to decide on actions , e.g. removing posts, attaching warning labels, etc. Those answering the questions know this, and (if they have a…

That's a very interesting system! I've been reading about it but I'm not sure how it applies. > (if they have a preference over which action will be taken) are incentivised to give more extreme answers. With yes and no answers, how can answers become more extreme? If you are asked "Is this misleading? Yes/No" and it's only marked as misleading when "Yes" is the majority, then you are incentivized to answer with your…

For yes/no questions I think (but haven't checked the math) that the incentive is to shift the distribution closer to my opinion. If my opinion is, say, 75% that it's misleading, then the truthful response would be a coin toss with bias 75%.

However, if I know my answer will affect censorship, etc. then I may try to predict the resulting distribution, and vote yes if I predict it's less than 75%, and no if I predict it's more than 75%.

For example, I may be more "trigger happy" if I think people are more likely to believe something uncritically; I may be more of a "devil's advocate" if I think something is under-represented, or less likely to be taken seriously.

I'm not sure I'm close to solving it, but I have an approach that I'd like some feedback on. I have a corpus of text in many Indian languages, which i'd like to index and search. The twist is that I'd like to support searches in English. The problem is that there are many phonetic transliterations of the same word (e.g the Hindi word for law can either be written as "qanoon" or "kanun"), and traditional spelling corr…

I'm not sure I understand the problem specification. You want to be able to search "law", and find documents containing "qanoon" or "kanun", right? How does your proposed solution handle that? It seems like the approach with ML TL -> Lucene would still only find one of the two, unless your model is written to return a set of possible transliterations. Or are you saying your approach doesn't currently solve this part…

No, sorry for the confusion. I want to be able to type “kanun” or “qanoon”, and have it infer the Hindi word “कानून”, which is an indexed word.

It is not necessary that there is a one to one correspondence between words. Sometimes two english words may represent one hindi word, or vice versa.

I believe I can build up a decent sized training/validation set, for example from Bollywood song lyric databases written in English, and mapping them to the Hindi equivalent (or Tamil, Bengali, etc).

As for your last question, I dont know, since I haver implemented an ML model in practice. I saw a tutorial on Bert this morning, where a word has 768 features. That itself sounds huge, leave alone the model itself.

> how closely the estimated distribution matched the real answers > A similar analysis applies to answering the second question (the estimates) truthfully. How does this avoid (or compensate for) downweighting the preferences of people who are legitimately ignorant about what everyone else thinks (and consequently give estimated distributions that hardly match the real answers at all)?

The weights can incorporate a factor (0 Although truth-telling is a Nash equilibrium of this setup, it's not the only one. However, as α → 0 the truth-telling equilibrium becomes dominant (i.e. achieves a higher expected payoff).

I try to find an agile project management tool that works for us. We run on what many would call Scrum (it’s not actually Scrum). We are on JIRA now, and it’s … JIRA. We tried basically any other tool, including Excel (yes, that is somewhat possible). My problem generally is that tools are slow, planning is cumbersome, visibility is limited and reporting for clients is often even more limited. Heck, I’d even write my…

I've been thinking for a while about building a tool to generate ETL/ELT jobs for data warehousing. Yes, there are lots of such tools already, but I've become frustrated in one way or another with all that I've used so far (mainly with their bloated size and clunky "repositories" and inscrutable runtime engines). This "while" that I've been thinking is stretching out -- the other day I stumbled across my earliest vague musings on the subjects, and noted that they are a couple of years old already, so I'm beginning to think it's time to stop thinking and start building...

For various reasons -- mainly familiarity, FOSS ecosystem, and cross-platform compatibility -- I'm going to try to implement this in Free Pascal / Lazarus. There is one kind of component I'm definitely going to need, and if there were a ready-made one I could use in stead of building one from scratch, it would save me a lot of time and effort. I've looked around online, but so far haven't found "the perfect one". So, my question is:

Can anyone recommend a good FOSS graphical SQL query builder component -- i.e, one which presents tables and their columns to the end user, so they can specify joins and filters by clicking and dragging, etc -- for Lazarus (or in a pinch Delphi, to port to FP/L)?

2 – can you possibly replace them with higher resolution ones after the scene is already running? Ideally, gradually with a blend over ~1 second.

3 — I see. Still, you could pre-compute local illumination automatically in the editor, and bake it somewhere. Maybe into vertex attributes, maybe into another lower-resolution R8_UNORM set of textures.
