Cultivating your data lake

This post by Lauren Reeder of Segment goes over the different layers to consider when working with a data lake. What’s a data lake, you ask? A data lake is a centralized repository that stores both structured and unstructured data and allows you to store massive amounts of data in a flexible, cost effective storage layer. Her article explains what tools are needed and provides code & SQL statements to get started. 🤟

JSON github.com

Free HTTP based JSON storage

A HTTP based JSON storage. It lets you store, read & modify JSON data over HTTP APIs for FREE. Ideal for small projects, prototypes or hackathons where you don’t have to spin up your own data store. Please don’t store anything mission critical here, but like the quote above says this could be a nice option when you just need a place to temporarily dump some data you’re working with. Simply grab a BOX_ID from the homepage and then POST away: curl -X POST 'https://jsonbox.io/$BOX_ID' \ -H 'content-type: application/json' \ -d '{"name": "Schrute", "position": "Assistant (to the) Regional Manager"}'

nve differentiates itself from nvm run because it: can be run programmatically is 10 times faster does not need a separate installation step for each Node version works on Windows does not require Bash is installed as a Node module Worth noting: this is not a full-on replacement for nvm or any other version manager. It only executes a single command with the specified Node version. But sometimes, that’s all you need. 😄

Minify Your SVGs

Victor Zhou uses a lot of SVGs on his blog. Do you? So now he optimizes their size as part of his build process. Do you? 62 SVGs minified, reducing the total size from 459322 bytes to 208897 bytes, a reduction of 54.5%! That’s a total of 250 KB, or 4 KB per SVG. Keep in mind that all of my SVGs were already saved in the Optimized SVG format - these savings were on top of already optimized SVGs. If you haven’t thought about minifying your SVGs before, chances are you’d see much more drastic results.

Use SQL to query & transform data from multiple databases & file formats

OctoSQL is a SQL query engine which allows you to write standard SQL queries on data stored in multiple SQL databases, NoSQL databases and files in various formats trying to push down as much of the work as possible to the source databases, not transferring unnecessary data. OctoSQL does that by creating an internal representation of your query and later translating parts of it into the query languages or APIs of the source databases. Whenever a datasource doesn’t support a given operation, OctoSQL will execute it in memory, so you don’t have to worry about the specifics of the underlying datasources. If you like writing SQL, you’ll probably like OctoSQL.

Startup idea checklist

I’ve been tinkering with different startup ideas and needed a good checklist to think through them. There are great templates for this already: The YC application, Amazon’s internal press release, and Sequoia’s Writing a Business Plan. I found myself mixing and tweaking these templates because they don’t exactly match my model of the world, so I wrote up my own list. These are great questions to ask yourself when you’re dreaming up an open source project as well.

How to automatically backup a Linux VPS to another cloud service provider

Cloud lock-in isn’t an issue until it is — “any amount of backups are just more eggs in the same basket if everything is under one account.” Most of the popular one-click server providers (including DigitalOcean, as well as Linode, Vultr, and OVH) provide their own backup offerings for an additional monthly cost (usually proportional to your plan). But as Nicolas learned the hard way, any amount of backups are just more eggs in the same basket if everything is under one account with one credit card on one provider. Luckily, crafting a DIY automated backup system using a second redundant storage provider isn’t as daunting (nor as expensive) as it might sound. The following steps are how I backup my various VPSes to a totally separate cloud in the sky. Jake Jarvis writes on his personal blog how to backup various VPS’s to a totally separate cloud provider.

An example to-do list app using SwiftUI (introduced at WWDC 2019)

SwiftUI didn’t get as much air time as the new Mac Pro and its ridiculous (in multiple ways) 6K display, but looking back at Apple’s 2019 announcements, SwiftUI might end up being the most profound of them all. If you want to cut straight to some working code and an XCode project that uses the brand new UI framework, check out the linked repo.
