Easiest method is using the subprocess module. If you're using Py3.5+ (you should be) see: https://docs.python.org/3/library/subprocess.html#subprocess.run

I am thinking to introduce readers to concepts like SSO, audit logging, feature flags, role-based access controls, reporting, exposing integrations, analytics, app metrics, etc and show practical implementation using code.

These general concepts aren't going away anytime soon, but writing a new book specific to a PHP product (in 2019) would be outside of my comfort zone. What is your audience?

I'm doing lightweight PHP programming using the macOS-integrated PHP server. I'm currently in the process of coding my own contact form but I'm struggling to find a working way to send test emails from my localhost (macOS).

I don't mean for each individual app and how they access them, but rather if and how you manage all of them in one place. Do you use a password manager like 1Password to keep track of them? Many API keys you could just retrieve from the associated site when you need them. But some of them only show you the API key once upon creation.

I have used 1Password for years and it's great. I'll store api keys, etc in Secure Notes and mostly on the servers via .env files or environment variables.

I have two projects I am working on that are mainly based around maps. I am just struggling to find the best way to develop them (I am a novice with little to no coding ability, but I am actively learning). First Project- - 100% map based - Tied into database that I run with scoring and information - Users can add new projects through the website, creating hotspots of actvity. Project 2: - 100% map based website. - Tied into database with POI information - Users can add into the POI database by providing tips, new info, suggestions Does a tool like Mapbox have this capability? Or are there any other alternatives?

Mapbox will likely be your bet bet. Their free developer tier is generous as well. You will need GPS coordinates that you can then feed to Mapbox to plot on a canvas. For the POI's you should leverage their symbol or popup hover options that come baked into the API (https://www.mapbox.com/mapbox-gl-js/example/popup-on-hover/)

I am using Heroku to deploy my project and mlab for mongodb database. Now I want to store the profile pictures somewhere. Storing them in mlab is not a good option. The only option I can think of now is using a CDN? How are you storing images?

You _could_ store an image in your database as a _blob_, but that's generally not a good idea as most databases aren't optimized for storing binaries such as images. Considering Heroku has an ephemeral file system (i.e. you cannot persist uploaded files on the disk) your best approach is to upload the files to some online storage such as Amazon S3. (I think that's what you meant with CDN, but it's not exactly the same thing.) The way it would work is the user uploads the file to your server (Heroku), and then your app uploads the file to your S3 bucket. Whenever you want to show the image you use the S3 URL. Alternatively you could configure your S3 bucket such that the user can upload directly to S3 without the file ever touching your server. This generally provides a better user experience, but technically is a lot harder to achieve in a secure fashion. So my advice is not to bother with that until upload performance becomes a real issue. Finally, the last option would be to use a SaaS that provides you with an upload widget, and takes care of uploading/processing/hosting files for you. [Cloudinary](https://cloudinary.com/features/file_upload_storage) has this feature.. This might be the easiest option, but probably the least flexible and most expensive.

this is the website https://bound2.app it comes in with a decent score on pingdom. And the page size is just 1.1MB. But the "wait" phase is nearly 15 seconds. And I can't work out why. Perhaps an old version of webpack / node config problem? This is a link to my github => https://github.com/crowdform/bound2web The project is really simple, so webpack / server.js files are possibly the ones. I'm using old webpack. Massive thanks.

1. Minify CSS, JS, HTML. 2. Paste your CSS and JS inline. 3. Optimize images and make a sprite. Right now you load like 20 or 30 images and even more, not from your server (not sure how aws3 fast, tho, but I would better load them from your server). With sprite you will download only 1 single image instead of all these 20 or 30. Here you can read about it - https://css-tricks.com/css-sprites/ Some more tips - https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fbound2.app%2F&tab=desktop

The easiest way to visualise what I want want is by taking a look at this image => https://s3.amazonaws.com/bound2/example.png Basically want the images to "bounce" round the website similar to this => http://next.plnkr.co/edit/HTHkXaD2BCFWTCK5tROi?p=preview&utm_source=legacy&utm_medium=worker&utm_campaign=next&preview The example above uses canvas! But I'm not sure if you can drop images into canvas easily? I can't seem to find any library out there. Any help massively appreciated!

Break up the problem in smaller bits and then tackle them one by one: 1. Create code example with image on canvas: https://stackoverflow.com/questions/6011378/how-to-add-image-to-canvas 2. Make image move on canvas 3. Detect when image reaches edge of screen 4. Make image bounce when reaching end of screen

No language is better than another... as long as you ship (or at least try to). Every man for himself. :)

Anybody here use Websocket on Rails 5.2? I have been trying to deploy the Chat feature on my app which based on Websocket to the production server but always got this error: WebSocket connection to 'ws://my_ip_address/cable' failed: Error during WebSocket handshake: Unexpected response code: 404 and this: WebSocket error occurred: One or more reserved bits are on: reserved1 = 1, reserved2 = 0, reserved3 = 0 I have asked the question on Stackoverflow and open a github issue as this might possibly be a bug within Rails/Passenger itself as I believed that all my configurations are correct. Here is the links to the question: Stackoverflow: https://stackoverflow.com/questions/52175211/actioncable-rails-5-passenger-failed-error-during-websocket-handshake-unex Github issue: https://github.com/rails/rails/issues/33845 https://github.com/phusion/passenger/issues/2116 I have been stucked with this for weeks, and nobody seems can help with this including the mentors on Hackhands and Codementors. So posting here is my last resort. Any help is very much appreciated.

Can you get a clean new rails app w/ the most basic actioncable/chat implementation working in production?

I usually work with my 15" Macbook Pro, and sometimes at work with a external 21" 1080p. Now I'm considering to go further. Options are: 1) Simple: 24" 1920 x 1080 at 60 Hz . ( AOC - ultraslim ) 2) 21:9 UltraWide FHD (2560*1080) https://www.amazon.co.uk/dp/B01BV1XB2K 3) Double set of 1) ( for vertical display programming, etc ) Budget is 100-300 ~ €/$/£ Do you only work on laptops? How do you set your desktop environment? Any experiences, preferences or suggestions on perfect set up? Many thanks.

I have a Dell P2415Q 4K display (1080p retina) and my MacBook open next to it. Was thinking about getting another 4K display and closing the MacBook.

I've noticed that the replies to big famous social media accounts do pretty well. Often the top reply racks up well over 300 likes and gets followers etc ... Whenever Kanye tweets I want to autoreply with the link to https://phonemekanyewest.com and maybe yeezy.dating just to help spread the word amongst ye fans. ive used twitter npm module b4 but can't work out how to autoreply!

Try something like var stream = T.stream('statuses/filter', { follow: Kanyes_screen_name }); stream.on('tweet', function (tweet) { console.log("reply here"); });

I have tried to use many UI frameworks but they get in the way. That is, I want to make a particular layout but I am not able to find out how to make that layout using the framework. I don't think this is true for everyone. So how do you learn a framework so that you can use it to make any UI you want? Or at least confidently write custom CSS where really needed and leverage the framework for the most part.

I program in RoR and use bootstrap. I´m not very good with css so i usually buy a template for 20€ based on bootstrap, use the styles that i like and modify those that i don´t. I used to try to create all the styles from zero but that could delay the shipping of the project for a couple of weeks. Now i just try to launch ASAP and doing that allows me to be faster. So i guess my answer is i dont know and probably just practice, practice and more practice.

I use https://vectr.com with different fonts & add some text shadows to it & export it using SVG. Now that Vectr added ads & its irritated me, I've deleted it & switched to Sketch for making some cool logos 😜

Making a logo unique is about the idea behind it. Not the font of shadows. It should tell a story, makes people curious and make them wonder what is there more te discover.

Something like [rubocop](https://github.com/rubocop-hq/rubocop) perhaps? That's what I use since a half a year or so. Takes some getting used to, but has helped me clean up my code a lot. Make sure to follow the installation instructions as it has some handy info on creating a "todo/ignore" file for existing style violations. That way it initially ignores those and you don't get bombarded with tons of warnings right out the gate. You can go through that todo file step by step and slowly remove stuff so it starts warning about those style violations which you can then fix one at a time. It's only for Ruby code. Not for Javascript, HTML, CSS, HAML, etc. I haven't researched those options yet (I know there are a bunch), but I will at some point.
