Did anyone else solve the puzzle after finding a bug in today's puzzle where on step 13 the circle you were trying to match didn't change, but should have?

Oh, nevermind, it appears others noticed this bug, too!

Cleaning up of feature flags was something that I excelled at failing to do. If you are the one cleaning them up, then you sir deserve a raise. Don't question it. It's a service.

Now if your site was named wafflehurricanetracker.org it would have probably survived trademark issues. The scraping issues would have been better if they were anonymized - it wouldn't necessarily be obvious that it was Waffle House (TM) that you had scraped, but if you suggested it was made by slow scraping websites of one or more popular breakfast establishments, then it wouldn't have been obvious.

It's also worth noting that in systems that get as large as Google's that you end up with commits landing around the clock. It gets so that it's impossible to test everything for an individual commit, so you have a 2nd kind of test that launches all tests for all branches and monitors their status. At Google, we called this the Test Automation Platform (TAP). One cool thing was that it continuously started a new testing run of all testable builds every so often -- say, 15 minutes, and then your team had a status based on the flaky test failures vs solid test failures of if anyone in any dependency broke your code.

So if your code is testing fine, and someone makes a major refactor across the main codebase, and then your code fails, you have narrowed the commit window to only 15 minutes of changes to sort through. As a result, people who commit changes that break a lot of things that their pre-commit testing would be too large to determine can validate their commits after the fact.

There's always some amount of uncertainty with any change, but the test it all methodology helps raise confidence in a timely fashion. Also decent coding practices include: Don't submit your code at the end of the day right before becoming unavailable for your commute...

Have you tried Luau - Roblox's open source compiled Lua with Types? Someone made a debugger for it that plugs into Visual Studio Code.

https://github.com/luau-lang/luau/ https://github.com/sssooonnnggg/luau-debugger

I'm working on an engine based in C++, Luau, and OpenGL - started almost 2 months ago. I aim for it to me MIT license open source, but it's too early for sharing. When it is, I do plan to post a show HN with the Github link.

You realize that you just gave hacker news gave enough details to commit some satellite controlling backdoor into their system... It's not like some of us aren't going to be like: "Yeah, let's get 'em!" Not me. I'm the ethical type, but some people might think:

Step 1: Modify OSS repository to gain control of satellites Step 2: ... Step 3: Profit!

slippy | 1 year ago | on: Ask HN: Promoted, but Career Path Derailed

"At first, the senior director didn't outright tell me I couldn't stay in the old domain, but made it very clear it was in my best interest to move to the new domain, where there wasn't a staff+ engineer."

Do you think this was good advice? You took their advice, even if it seemed a bitter pill at the time. They were most certainly part of the process for your promotion.

It feels like this senior director is in your corner. I'd schedule a 1:1 with a simple agenda of "looking for advice".

Definitely start with a compliment. "I remember that you advised me to move to X, Y time ago, and you were right that it was great for my career and promotion."

Be clear and specific about your desires - "I miss working on X technology. I was wondering if you have any visibility into any 2025 Q2, Q3, H2 projects or opportunities related to X technology that I might be able to [contribute to or transition to]." Sometimes you can be 50/50 to try something out or dip your toe in the water if you are attached to the success of something else. It's important that you be clear and specific. Maybe you could do this via email - it depends on if you are introverted or extroverted.

I once had an EM go back to Principal IC in an area that he loved. He's still working on it.

Good luck!

I read through a whole page, wondering when we are getting to legal stuff, before I went back and re-read the title. "Contact" not "Contract"....

slippy | 1 year ago | on: The number pi has an evil twin

I am a native speaker and got the gist and saw the paradox, and found the phrasing a bit tortured by the triple negative. Thank you for explaining that this was a colloquialism. Now I have to go look up the etymology... And upon further inspection, this usage is actually a misnegation.

"It is a veiled insult: an ironic form of insult delivery which is misinterpreted as flattery to the buffoon who is targeted by it, much to the entertainment of anyone else within earshot who understands the true meaning."

slippy | 1 year ago | on: The number pi has an evil twin

Hmm. Why only 2? Why not 3 points? Can you find an interesting curve produced by a constant product of distances from N points? Maybe even in higher dimensions, for 1 point, you have a sphere. What is the shape for 2 points? Is it more like an hourglass-like double droplet?

How many other domains were knocked off by this AI reporting? Seems to me that if you make claims that have business repercussions, you need to be suable for fraud and face civil and possible criminal complaints.

Legit question: By _removing the MIT license_ from the distribution and replacing it with the AGPL, how are you not violating the copyright and subject to a lawsuit?

The MIT license has just 2 conditions. They are pretty easy to read, and the fist one is:

The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

By replacing the license, you violate this very simple agreement.

I donated a kidney to my father 10 years ago. It took about 4 weeks of recovery before I could get on a plane to fly home. Even 10 years later, I have not recovered to the same energy level I had before the surgery - something about the original surgery never quite healed right, and my kidney function gets monitored every 6 months or so at the doctor's office - I take a few medications to protect my remaining kidney. My father is still alive today because of it. It is important that if you do this, that you have plans and support. It is not for everyone.

slippy | 1 year ago | on: The war on remote work has nothing to do with productivity

Alas, it's a nuclear option.

People are going to stay or leave based on random criteria. Your company is going to be left with various deficits and it will take a long while to sort out the hiring mess.

This feels more like it's about power. Those with the power leave, likely to competitors.

slippy | 1 year ago | on: Data center emissions probably 662% higher than big tech claims

The simple answer to this: Tax the #### out of the greenhouse gas emitting energy sources.

If we as a planet need to be using better sources of power so that our planet literally doesn't melt our food sources, and then us, then our governments need to make it more cost effective to use better sources. Carbon credits or energy swaps don't work to actually reduce the amount of polluting energy produced.

The classic time space tradeoff question: If I run Antithesis for X time, say 4 hours, do you take periodic snapshot / deltas of state so that I don't have to re-run the capture for O(4 hours) again, from scratch just to go back 5 seconds?

slippy | 1 year ago | on: Intel's Thunderbolt Share is a speedy sneakernet replacement and more

Funny. It worked just fine when I was in college, back in 1997. You could use VNC to share either direction, or X11 to share one-way. Also SSH/SFTP, and SMB all worked. There were SFTP servers on Windows for free - you could download them off the internet and run them on Windows 95, 98, XP, etc.

Moving files between devices has never been difficult.
