Interviewing a developer for whom English wasn’t his first language and he kept calling legacy code “legendary code” and now that’s all I want to write.
awesome-falsehood: Curated list of falsehoods programmers believe in (via) I really like the general category of “falsehoods programmers believe”, and Kevin Deldyckehas done an outstanding job curating this collection. Categories covered include date and time, email, human identity, geography, addresses, internationalization and more. This is a particularly good example of the “awesome lists” format in that each link is accompanied by a useful description. # 8th April 2018, 7:57 pm
Code is like a poem; it’s not just something we write to reach some practical result. Sometimes people that are far from the Redis philosophy suggest using other code written by other authors (frequently in other languages) in order to implement something Redis currently lacks. But to us this is like if Shakespeare decided to end Enrico IV using the Paradiso from the Divina Commedia. Is using any external code a bad idea? Not at all. Like in “One Thousand and One Nights” smaller self contained stories are embedded in a bigger story, we’ll be happy to use beautiful self contained libraries when needed. At the same time, when writing the Redis story we’re trying to write smaller stories that will fit in to other code.
By far the most important lesson I took out of this game is that whenever there’s behavior that needs to be repeated around to multiple types of entities, it’s better to default to copypasting it than to abstracting/generalizing it too early. This is a very very hard thing to do in practice. As programmers we’re sort of wired to see repetition and want to get rid of it as fast as possible, but I’ve found that that impulse generally creates more problems than it solves. The main problem it creates is that early generalizations are often wrong, and when a generalization is wrong it ossifies the structure of the code around it in a way that is harder to fix and change than if it wasn’t there in the first place.
What’s the cheapest or free stack solution to deploy and experiment with a realtime application in 2016?
Heroku have a good free tier, and comprehensive support for deploying both Python and Node.js. If you are mainly interested in realtime I would suggest starting out with Node.js on Heroku. Depending on the complexity of your project you might even be able to use raw Node.js without adding something like Express.[... 81 words]

Is there a substantial difference between using a Mac or a Windows machine for web development (particularly RoR)?
No matter if you are on Mac or Windows you should be using a Linux virtual machine for development, ideally running the same operating system as you deployment environment (I like Ubuntu for this). Vagrant is a popular tool for managing this kind of setup.[... 151 words]
Learning Linux really isn’t that hard, and it will dramatically increase your potential horizons as a programmer. Install Ubuntu on a virtual machine on your laptop and start running through some tutorials.[... 53 words]

Pricing isn’t about how hard it is to build something (and building a reliable, highly-scalable centralized log search and archiving system isn’t trivial). It’s about how much value it provides to the customer.[... 204 words]

Using AWS, as my cloud, what is left for me to work on? Is it enough for me to just write the html+css code and programming language code (python)? Or do I stil have to work with mysql and backend stuff? I am pretty new at programming, so I hope it i...
Using a cloud server platform like Amazon EC2 unfortunately will not protect you from needing to understand basic server adminstration—it’s not that different from running your own physical server, except that if you screw up the configuration it’s much easier to throw everything away and start from scratch.[... 134 words]

Yes. OOP is a very important programming concept—a professional programmer who is not familiar with it will be unable to understand vast swathes of high quality existing code and will have a great deal of trouble passing interviews or contributing effectively at great companies.[... 95 words]
I think this is a pretty interesting idea—simulating these kind of conditions isn’t easy so I imagine many teams don’t bother. If it was good (really easy to get started with, great control and reporting tools, maybe helped set up the actual tests to replay) and I trusted the service I would definitely consider paying for it.[... 125 words]
As a general rule it’s not a good idea to allow mobile devices to connect directly to a server-side database, as it’s an invitation to hackers to figure out what’s going on and then connect to the database themselves for nefarious reasons.[... 105 words]

For a Django application, deployed on Heroku, what are my options for storing user-uploaded media files?
S3 is really a no-brainer for this, it’s extremely inexpensive, very easy to integrate with and unbelievably reliable. It’s so cheap that it will be practically free for testing purposes (expect to spend pennies a month on it).[... 88 words]
Just because something is popular doesn’t mean it’s right for every person, every problem or every situation. If no one ever explored non-mainstream options, better solutions would never be discovered.[... 47 words]
This is a big decision, and it’s worth taking the time to pick what’s the best fit for you. I recommend going through the tutorials for each one, building the basic application they describe and seeing which made the most sense to you. As a Django developer, I suggest trying that framework too :)[... 126 words]
What are some techniques, workflows, thought-processes etc. you would do as an experienced web-developer (front-end/back-end) that a new web developer might benefit from?
Maybe. One of the things I like about Node.js is that the raw abstraction it provides over HTTP is much closer to how the actual protocol works than the abstractions provided many of the more widely used frameworks such as PHP, Django or Rails. That might actually make it an effective learning tool—I’d be interested in hearing from some web developers who learnt Node.js as their first server-side technology.[... 87 words]
