At the beggining I'd like to say it's not an emergency :D
I was thinking about project ideas recently. Projects that I could try to create to learn something more, something new or just to leave my comfort zone. I've picked notes app project that support handwritten notes. And here's the first problem, my little knowledge can't come up with idea how to store these handwritten notes in database.
Database or other technologies haven't been picked yet so there is no "How to store it in MySQL?" and so on... just theoretically thinking how it could be done. I was looking in google and here on stackoverflow but didn't get nothing similar, just some questions how to verify or recognize handwritten notes.
Has anybody any idea or lead I could go by?
Here I am assuming your "handwritten notes" are images. A simple solution might be uploading your images somewhere (e.g. Amazon S3, but there are countless options out there). Then, in some database you might have a reference to the URL of the image. In your code you can then download the images using the URL and process them as you see fit.
Note: I am making many assumptions here but I hope this helps.

This seems like it should be a simple question, and I apologize if this is stupid to ask, but I have been scouring seemingly every corner of the web and still have absolutely no idea how to even begin saving pictures.
For my specific case, I am working in React Native and an important function of the app is to take pictures and save them in a manner where an admin account can later access those images.
I sincerely have no idea how to do this. I know you can through AWS S3 Buckets, but I've heard nothing but bad stuff about them, ad my current experience on AWS is pretty rough so I'd prefer avoiding that. I tried something called contentful, but never was able to determine how to connect to the API from inside my code. Supabase was another option, but the Client simply refused to work, and it still seemed overly complicated and i wasn't easily able to find any JS code that would upload. Now I'm working with Cloudify and I was able to find the code needed to upload pictures to it... but I have no idea how to create an account with the proper storage / organization and then extrapolate the information later. I feel like this shouldn't be as convoluted as it is, does anyone have any suggestions, ideas, or experience with Cloudify?
try firebase from google. fireship (name similarity coincidence) channel on youtube has convinient and easy to understand tutorials about firebase.
I am currently designing a reviews site for video games similar to gamespot am wondering where and if there is an online database that contains information such as name, publisher, release date etc with an API. I dont really want to have to enter each title manually or let users enter the title manually.
Where do these large sites get information like this? I wouldn't think it would be manually. I know for movies IMDB exists.
How would I go about adding it to my database?
Thanks
May I point you to web scraping?
Be sure to read the section legal issues and on well-behaved bots.
There's always Amazon and their product advertising API. Some older, but interesting code snippets can be found on this page.
If you know Perl, there is an amzing module called WWW::Mechanize
Pretty much you can write a script to get to any website and grab any data you need.
So for example you can go to www.gamespot.com, get list like the one below and put them in your database.
http://www.gamespot.com/games.html?platform=1029&mode=all&sort=views&dlx_type=all&sortdir=asc&official=all&tag=games%3Bfooter%3Bmore
I know it has great out-of-the-box features but is it easy to customize?
Like when I query stuff from the database or change css layouts.
Is it faster to create my own modules for it or just go on and write everything from scratch using frameworks like Cake
I'm currently working on an Elgg-based site and I absolutely hate it. The project was near completion when I stepped in, but the people who created were no longer available, so I took it over as a freelancer.
As a personal impression, you are much better off writing the app from scratch in a framework. I don't know if the people before me butchered it, but the code looks awful, the entity-based relationship model is wierd to say the least and debugging is horrendous. Also, from my point of view, it doesn't scale very well. If you were to have a consistent user base, I'd be really really worried.
It keeps two global objects ($vars and $CONFIG) that have more than 5000(!) members loaded in memory on each page. This is a crap indicator.
I've worked extensively with cake. With Elgg, for about a month in a project that is on QA stage right now.
My advise is: if you need something quick with a lot of features and you only need to customize a little, go with Elgg.
If you're going to customize a lot and you can afford the development of all the forums, friends, invites, etc. features, go with Cake or any other MVC framework.
I have been working on a Elgg site for the past month or so, its code is horrible, however it's not the worst I've seen :D. it's not built for programmers like Drupal is :D. But it's not too bad. Once I got a handle on the metadata functions and read most of the code I was able to navigate it well and create custom modules and such.
What would help immensely would be some real documentation and explanation of the Elgg system. I don't think that's going to happen though :).
Out of the box there are a few problems, there are some bugs that haven't been fixed for a while and I've had to go in and fix them myself. Overall, you can make it pretty and it has some cool functions, but i wouldn't dive in until i had read the main core code to get a handle on what's happening on the backend.
Oh and massive use of storing values in globals. and a crap ton of DB calls (same with Drupal though).
i wonder if the use of storing everything, and i mean everything for your site in the globals will really hinder the server if you have a massive user load.
If you want to build a product based on a social networking platform/framework then Elgg is definately a good way to go. The code is not that bad if you actually look before leaping and doing what elgg expects. You go against its processes and structures and it will leave you beaten by the side of the road.
Developing modules/plugins or editing CSS is easy and Elgg does give you great flexability to basically build your own product ontop of it. Dolphin, as comparrison, does not allow you to do anything outside of what it expects you to do.
If you however just need a framework (not primarily for social networking etc) with some user based functionality then i suggest Cake, or if your project is HUGE then maybe Symfony or Zend. They all have plugins you can download and use/hack which would be easirer to adjust for personalised needs.
To show what you can do with elgg here is a site Mobilitate we built with Elgg 1.7. This is a very complicated website and was built ontop of Elgg.
We are starting a new project with Elgg 1.8. The new version is a major improvement they have made a lot of elements easier, incorporated better JS and CSS implementation/structure and have better commented their own code.
Elgg's database schema is horrific. They've essentially implemented a NoSQL database in SQL. It completely defeats the purpose of using a relational table structure.
If you can ignore this, and aren't doing much customization, you might be OK with Elgg. If not, STAY AWAY.
I've been working with Elgg for over a year. It is easier to customize than it would be to build something from scratch using a framework like CakePHP. I tried CakePHP and found it even more complicated than Elgg.
It is difficult to query the database due to the entity-based relationship model. You should use the build-in methods for accessing data. However, I have written many queries to double check on what is actually stored in the database.
You cannot change layouts using CSS alone. You have to deal with the various Elgg views. But CakePHP uses the same Model/View/Controller MVC concept so that would be just as difficult.
So, here is the task I've found myself thinking of. Pretend for a moment, that I have a large body of content. I want to see what websites are linking to my content. I know that I could look into TrackBack or PingBack but what about those that aren't using tools capable of dealing with that?
It would seem that some form of Web Crawler that looks for pages linking to the original document might be useful. My question to the greater community is what would be the best way to get started here? Do TrackBack and PingBack do more than I assume? Are there services or tools out there that already do what I'm thinking?
Google is your friend!
Use the link prefix:
link:whatsite.com
And yes, trackbacks do more.
If you have HTTP referers setup in your logs, you can mine them.
You can even discover pages taht does not know about.
Else, there is the paying Linkscape from Seomoz or the free majesticSEO (if you confirm ownership of the domain).
MajesticSEO has a bigger backlink index and an API (need to login!).
Does anybody know if there is a way to understand what users are doing on my web page? I can see overall stats with Google Analytics but I can't really understand what users are looking at, if they are reading my content, etc.
Does anybody know if there is a free or paid service that I could use?

You could try using one of the analytics things that does heatmaps.
These give a visual representation of where people are clicking on the site, and I think some may let you track where the cursor is as well.
This is about as close as you can get to what you want - there's no way to track what someone's eyes are looking at,
Wikipedia claims that google analytics can do this. I've not seen it in analytics, but it may well be hiding there somewhere. I have used clicktale a bit before though:
http://www.clicktale.com/
Try Mouseflow. You can even record your visitors and watch the videos. Haven't tried it but looks promising.
The Site Overlay report in Google Analytics is probably what Wikipedia is referring to. However, it doesn't work most of the time (it's a "piece of crap" in Google's own words).
ClickTale is okay. I recommend CrazyEgg: http://crazyegg.com/
