Most "how we built it" write ups start with the tech stack. This one starts earlier: with 300 conversations a founder had with procurement leaders before deciding what to build at all. Omnea's founder, Ben Freeman, spent that discovery phase hearing some version of the same complaint repeatedly, that procurement processes were widely disliked and the tools available were clunky, but nobody had actually rebuilt the stack from scratch. Why this matters more than the eventual tech cho...

The worst bug I've seen in a test suite wasn't a failure. It was a pass. A login test tapped a button labeled "Continue". The app then shipped a second "Continue" inside a consent sheet, and the recorded test — which resolved its selector by taking the first match — started tapping the wrong one. It stayed green for two weeks, because the flow still ended up somewhere plausible, and a passing test is not something anyone goes back and reads. So that became the rule for tapflow's flow runne...

Two days ago I changed the tags on three of my own posts, added cover images, and watched reads go from 2 to 45. That is an anecdote with n=3 and a proud author attached to it, which is worth roughly nothing. So I collected 16,599 articles from the public API across 20 tags, kept the 11,450 that had been up for at least 72 hours, and looked at what actually separates the ones that land from the ones that do not. 78% of them got zero reactions. Not few. Zero. The median article on this pl...

Writing SELECT , INSERT , UPDATE , and DELETE queries is not the difficult part of a CRUD API. The difficulty begins when every route starts handling SQL, input validation, HTTP status codes, and error formatting at the same time. That version may work for five endpoints. It becomes unpleasant when you add authentication, pagination, related tables, or a second developer. In this tutorial, we will build a Node.js REST API with Express and MySQL while keeping each responsibility in a p...

If you run Netdata on one to three machines at home, the local agent dashboard on port 19999 plus the free Netdata Cloud tier covers almost everything you need, and a paid plan rarely earns its keep across three years. Pay only when you need durable multi node views, alert routing that reaches other people, and role based access you can revoke. Self hosting a Netdata parent node is the cheapest route to long retention and one dashboard for every child node, and the price is one always on machine...

HELO vs EHLO: Why Your SMTP Greeting Can Hurt Email Delivery Your SPF, DKIM, and DMARC records may all look correct while your mail server still introduces itself as: EHLO localhost or: EHLO server1.internal That greeting happens before the message body is transmitted and can become one of the first identity signals a receiving server evaluates. What HELO and EHLO actually do When one mail server connects to another, the receiving server fi...

Every developer has a folder on their computer filled with abandoned side projects. You know the one—it's where ambitious ideas go to gather dust after the weekend is over. Four years ago, BeGoodTool was just another one of those folders. It didn’t start with a venture capital pitch, a business plan, or a dream to disrupt an industry. It started because I was incredibly frustrated. I was doing some routine development work and needed to quickly format a massive JSON payload and conver...

We’re a fully remote SaaS company, and our security setup has slowly grown as the team and the amount of sensitive customer data we handle have grown. Right now we use Okta for SSO and MFA, 1Password for credentials, Cloudflare Zero Trust for internal access, CrowdStrike on company laptops, GitHub for development, AWS for infrastructure, and Kibu for private team communication and trusted connections. Individually everything has a purpose, but onboarding our latest hires made me realize how ...

Hello , I just created my first saas which is a CRM for sidehuslter because a friend requested and it was my end year project for my bachelor in CS.

And also was fired from my 3,5 years job . Because I feel good to develop my first application . But I have no client yet and maybe nev...

I have an autoimmune disease for which there’s currently no cure (hopefully there will be something soon). Because of that, I’m at home 24/7 and I’d really like to start something of my own. I’ve been doing seasonal online work for a few years and have saved up enough money, so I have capital to invest in marketing. Starting today, I plan to dive into extensive research to come up with an idea and eventually build something out of it. I’d really appreciate any advice, ideas, or anything yo...

Long post. I'm too deep in this to judge it clearly and I need outside perspective, specifically on what to actually do now. -> Background: We're both around 23, same age, no seniority gap. We've been close friends for about a decade: dinners, birthdays, the whole thing. About 15 months ago I came up with the idea for our B2B AI SaaS product. I did all the concept work myself: product vision, feature structure, user flows, monetization model. Then I spent the first 1-2 months building t...
