In the SPF vs DKIM vs DMARC comparison, SPF lists who may send your email, DKIM signs each message, and DMARC tells receivers what to do when a check fails. You need all three. Together they stop others from faking your domain and help your mail reach the inbox. SPF vs DKIM vs DMARC at a glance Each record answers a different question. The table shows them side by side. After it, we explain each one in plain words. Record Question it answers Where it lives ...

I have a tech background, I haven't been super active in coding or other things, but I still play with stuff a lot. And yet, in the past ~2 years, I often feel that it's pretty much impossible to keep up with the latest AI development (in particular regarding vibe coding), which in turns gives me less energy or determination to explore the latest thing. How do you feel about it? And did you find a solution to stay motivated to learn and get better at using AI? Comments URL: https://news.yco...

The U.S. Department of Energy can order a utility or grid operator to keep running generation under section 202(c) of the Federal Power Act. DOE lists those orders on its website as text. I put every order, extension and amendment from DOE's 2025 and 2026 pages into one CSV (85 rows), with a small standard-library Python script whose tests check the counts against the table. What the table shows, as of 18 October 2026: 66 orders, extensions and amendments in 2026 so far , against 19 in...

Design a CDN: the content delivery network system design walkthrough The request to design a CDN sounds like a one-liner — put the files closer to the users — and that one line hides the whole interview. A content delivery network system design is not a file server with extra machines; it is a globally distributed read-through cache where a request from a phone in Mumbai should be answered by a server a few milliseconds away instead of crossing an ocean to your origin, and where the ha...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle What I Built Independent contractors in India—plumbers, electricians, freelance event photographers, mechanics, and home bakers—spend their entire day doing hands-on work. The last thing they want to do at 9:00 PM is sit at a desk, open a spreadsheet, look up HSN/SAC tax codes, separate material costs from labor charges, calculate CGST/SGST splits, and format a PDF bill. Because of this fri...

Take a look at what the OpenSilver team has built. This game shows what C# and WebAssembly can do in the browser. How fast? Play it and see for yourself. Disclosure: I used to work with this team, so I know what they’re capable of. For those who don't know, OpenSilver was born long ago as a replacement for Silverlight, a kind of competitor to Flash (but way better). But, as usual, Microsoft killed it. Classic: from "this is the future" to "nah, HTML5 and React are the future." It compile...

Why it matters When a command fails in your project or CI, “it failed” is rarely enough to act on. RepoTrace saves the exact argv, exit code, stdout/stderr, working directory, and interpreter metadata so a failure becomes a replayable artifact — a single-file, JSON bug report that you can rerun, render as Markdown, or convert into a standalone pytest regression test. That preserves the signal of the original failure and turns debugging into a repeatable, auditable process. What RepoTrace i...

I make Just Every, a set of free, open-source alternatives to subscription work software, so I spend a lot of time deciding what a test should check. Nothing in the method below needs our code. A worked example from one of our products is at the end. Most test suites are organised around what the code does. I find a failure test easier to design from the other end: start with the wrong thing a user could see on screen. Here's an exercise for it. Run it on a throwaway environment with test ...

SQL Challenge. Find Departments with an Average Salary Above the Company Average Here’s a practical SQL interview question. Can you find which departments have an average salary higher than the company-wide average? Table 1: employees emp_id dept_id salary 101 10 80000 102 10 100000 103 10 90000 104 20 50000 105 20 60000 106 20 70000 107 30 40000 108 30 50000 Table 2: departments ...

Design a web search engine: the system design interview walkthrough The request to design a web search engine sounds impossibly large — "build Google" — and that size is exactly the trap. The sentence hides three separate systems: a crawler that discovers pages, an indexer that turns them into something searchable, and a serving layer that answers a query in the blink of an eye. A strong candidate says that out loud in the first minute, scopes the crawler to its own problem, and name...

If you are still opening a desktop GUI, hunting for your release DLL, and clicking an "Obfuscate" button every time you want to publish a C# or VB.NET application, you are leaving your CI/CD pipeline vulnerable to simple human error. In my day-to-day work as a Senior Software Developer building tools at Rustemsoft, I constantly see teams accidentally ship unprotected intermediate language (IL) simply because someone forgot a manual step. When we designed Opaquer .NET Obfuscator as the success...

Your baseline-prof.txt is committed, CI runs the generator task every release, and the dashboard shows a nice fat profile file in the APK. Cold start is still slow. Here's the thing almost nobody checks: a baseline profile can be present, committed, and completely inert — and your build will never tell you. The three ways a baseline profile silently no-ops 1. It was generated against the wrong build variant BaselineProfileRule from Macrobenchmark has to run again...

An AI note-taking interface can produce a summary, ten flashcards, and a quiz from one document. That leaves a product question: what should someone do with each of those outputs? A useful design gives each format a clear job, lets people check its claims, and keeps mistakes from spreading across the whole note. Here is a small design walkthrough using an invented specification. It is an illustration, not a report of a deployed product or a user study. Example source: recording workf...

Dominic Plunkett has updated the BBC Micro PiMHz software to emulate most of the hardware for a BBC AIV system, including the LV player! Just add a trackball/mouse and a PiTubeDirect and you'll be able to run the Domesday disc! This video covers how the PiMHz implementation works (basically!), how to set it up and gives a demo of the Domesday Community and National Discs. Comments
