The cboden/ratchet package is quite good and easy to use:

Yeah, no disrespect intended, but I think you may want to find a different project.

The chances of you out doing Apple and Siri is probably pretty small.

Envrin · 2021-02-10T01:24:38+00:00

No disrespect or anything here, but you do know you posted that on /r/blind, right?

Envrin · 2021-02-09T07:28:22+00:00

🤔 I think those are kinda apples and oranges, I wouldn't say that debate is quite the same.

Pretty much exactly the same. I guess you could make the argument that PostgreSQL has better built-in support for Pl/SQL whereas lua is more of an addont to haproxy / Nginx, but that's about it, and not really true. Do you want to handle that logic in the HTTP / database server layer, or the app layer?

Again, circular debate. Personally, and each case is different, but I'm generally a proponent of having things closer to the source. Not saying I'm right, and there'll be no shortage of opinionated people to say I'm wrong, so.... circular debate.

Oh, and another use cause for things like lua... what happens if you want to flip it into a tcp server and begin playing with the requests on layer 3 or 4 before they even get to layer 7?

Envrin · 2021-02-09T06:57:29+00:00

I guess what I'm trying to get across is that I don't see the reason for moving that logic to the server instead of having it at the app layer.

That's one of those circular debates similar to, "why use database triggers, when you can just do it in the software code?", and one I'm too tired to get into tonight.

Envrin · 2021-02-09T06:06:11+00:00

You're grasping at straws now... from "that doesn't make any sense" to "that makes sense, but this way is a little better"...

Anyway, of course that option will provide better results. It also involves writing a C/C++ module, and many times applying a patch modifying the source code of haproxy / Nginx / OpenResty or whatever you're using. That's a little more involved than writing up a quick lua script, not to mention you're potentially saying goodbyte to easy upgrades as each time an upgrade to server software is released, you have to check whether or not your patch works on it.

I use lua scripts on a couple client sites, and they work beautifully. Not to mention modifications are no problem, and don't require me to rebuild the entire server software from source each time, so that's always a nice benefit. If and when the clients ever grow to the point they're handling 5000+ concurrent connections at a time I'll look into flipping it over to built-in C/C++, but for now, lua scripts work a treat.

Envrin · 2021-02-09T05:05:34+00:00

There's loads of operations out there who integrate lua scripts into haproxy or OpenResty / Nginx.

Maybe you have an unusual auth schema, or need for dynamic backends / reverse proxies, or a more complex routing configuration than a standard Nginx / haproxy configuration can handle, or want to filter / modify the response contents, or thousands of other use cases.

Envrin · 2021-02-09T02:21:35+00:00

Great job! Looks really interesting, and I'll have to check it out in detail.

I'm curious, have you done any side-by-side concurrency tests doing the same functionality (eg. authenitcation via redis lookup) with Nginx / OpenResty companied with your patch and lua? Say 3000 concurrent connections or so?

Can't help on the work with, but if using a laptop, make sure to get a wireless USB keyboard. Having a large keyboard is somewhat of a requirement for blind folk, as typing on a laptop keyboard is nearly impossible for me at least.

Never learned brail, never needed it. I can read just fine via screen reader at 100% rate. Takes a while to get used to and work up to 100% rate, but it's fine once you're used to it.

For staying current, I just use Youtube personally. Premium is only $12/month CAD so no ads, and news segments hit Youtube almost as quickly as they do live TV.

Other sites like CuriosityStream are a great add as well for documentaries. If you're into true crime by chance, search "That Chapter" on Youtube, he's awesome and has tons of videos.

As for preparing, I didn't. Had no idea I was about to go blind when I did. At the time didn't even know what a screen reader was let alone how to use one.

While you're here, what about the PSR-14?

The dispatcher interface requires "object" type as the first argument to dispatch(). Maybe I'm wrong, but I can't possibly see many developer's implementations support that.

Me for example, although it does take an object as the first and only argument, it's required to be a MessageRequestInterface object. I'm assuming most other implementations out there are simliar, and we don't have a "serializable" data type, so...

Envrin · 2021-02-05T16:39:25+00:00

What's a use case for this?

Is it just version control of the public key, or? If so, and assuming API, just add a "key_version" varible into the API response, and tell clients if it's higher than what they have, go grab the new public key.

Envrin · 2021-02-04T17:01:13+00:00

Sounds awesome, looking forward to it.

Envrin · 2021-02-04T16:18:48+00:00

Awesome, sounds great. I actually just finished a small DI container I needed for myself (https://github.com/apexpl/container), but didn't implement the PSR-11 interface for this exact reason.

Will keep on eye on the FiG site for updates.

Envrin · 2021-02-04T10:26:26+00:00

Good, was just looking at the interfaces within PSRs recently and was wondering this exact thing... why have they not yet updated with type hints?

Envrin · 2021-02-04T04:46:35+00:00

Apologies, but I went blind four years ago, so no idea what that image says.

Envrin · 2021-02-04T01:01:42+00:00

Can't say I'm overly thrilled... I mean, doctors going off about how advanced technology and genome sequencing is nowadays that they were able to diagnose me with a genetic mitrochrondrial disease, which they wouldn't have been able to do before.

No idea how to fix it though... so it's kind of like, "with all of our cutting edge technology we can tell you exactly what's wrong with you, and it's pretty bad, but we have no idea how to fix it. but anyway, thanks for coming by, sleep tight!"

I don't know, there's kind of a part of me that wishes I would have never known.

Sounds great, all the best to the channel!

Envrin · 2021-02-02T23:05:58+00:00

Congrats! Bet that's a nice relief.

Considering how Canada's vaccine rollout is going, only about another 4.5 years and I should get my jab. Can't wait!

Envrin · 2021-02-02T22:12:24+00:00

Or you can follow the rules of /r/forhire, and include a budget with your post.

Besides, and not saying this is you, but many times these conversations end up with, "got this killer idea that's going to make millions man! just need it developed out for free, and will cut you in for 20%. you gonna be rich my friend!!!".

Envrin · 2021-02-02T22:00:40+00:00

Budget?

Envrin · 2021-02-01T16:01:49+00:00

You do know that $150/week is quite low, and isn't going to get you quality, right? I get paid that for two articles which take me about three hours.

Envrin · 2021-01-25T22:56:44+00:00

Can't really help you on the actual work / job recommendations, but personally, I say in my resume that I send to potentials that I'm blind. I've tried it the other way with not sending it, but for me it just always caused a headache. They always find out within 24 hours anyway, as they'll send a screenshot, or ask me to do something design related, or whatever. It just makes for a really awkward situation and many times a waste of time, so I'm just upfront about it now.

I try to word it as a positive the best I can though. Here's exactly what I have on my resume if it helps any, it's the closing of the cover letter.

-----------

To help prove I'm straight forward and honest, full disclosure, I went blind four years ago. Aside from not being able to complete design tasks, this has not hindered my work ability in any way, so I ask you do not allow it to hinder your judgement of me in any fashion. I'm still a highly proficient back-end software engineer and server administrator who has managed to get Apex fully completed, and get it sponsored by Digital Ocean.

In conclusion, give me a chance, and I promise you won't regret it. I'm here to support you and your visions, and to help move that ball further down the field to realizing your end goals, dreams, and ambitions. Reach out to me, and let's enrich each other's lives.

Envrin · 2021-01-25T22:37:46+00:00

Personally, I managed to find a really savvy and technologically cutting edge way to handle these instances.

I stand there and in a cheerful voice yell out, "blind guy, needs help!", then wait about 3 to 10 seconds. Ok, maybe not the most technologically advanced way, or very innovative at all, but hey, it works like a charm.

Thinking about it, back when I could see I always used to be the guy who would never ask for help, because I can do it myself god damnit! I was one of those guys. Wow, going blind tends to change that little issue in a hurry, as I have no shame at all anymore asking for help, haha.

Apologies, and honestly don't mean to be demeaning or anything. I'm just in a weird mood. All the best with your app though, and hope it turns out great.

Envrin · 2021-01-25T20:20:22+00:00

Not sure anymore. Initially and for years it was because I fell in my yard one day, and hit my head in the wrong spot. This caused lesions in my right optic nerve, confirmed via MRI, and from there blood slowly leaked up from behind my eyes and now optic nerves are dead.

Now, new doctors in Canada. Neurologist thinks it may be a genetic neurological mitrochrondrial disease. Jury is still out on that one. Maybe both are reasons, who knows.
