Yes, but at this point I'd almost rather have my CC info exposed than my personal info. There is law and consequence for fraudulent charges that protects me from loss (if not inconvenience) but there is basically no protection for playing fast and loose with my PII--in fact, it's the opposite! They sell it!

There was a time when I built games entirely using Visual Studio 6 Edit and Continue. These were the days when debuggers were reliable. Nowadays, I treat the debugger’s output like a best guess: it’s probably right about local variable values and the call stack, but it sometimes has nothing useful to say, and very occasionally is actively misleading.

Thanks for this -- have been using Cody a lot and just tried Windsurf on my hobby project. So far it seems immediately like a step up. Has anyone paid for it? The free version is doing good work.

If a company provides a service for free to enable selling something else, and that something else becomes illegal to sell, then it’s up to the company whether they want to keep offering the free service. They can’t continue doing things that are now illegal just because that’s how they made money in the past. No decision-making power has been taken away.

Congratulations! Happy to hear you describe making an indie mmo as fun and not that hard these days :)

Is there a way to interact or chat on mobile?

Any recommendations?

Check out the Winternitz One-Time Signature

Sphere10.com/articles/cryptography/pqc/wots

Signing many things with one identity is possible by precomputing a Merkle tree, but this takes time and the signatures get big.

Google Apps Script can do all of this. Take the email body and put it into a Google doc, then export the doc as a pdf to drive and attach it from there to send.

Wow, the exact opposite of what I might have guessed from the title.

Does this mean percutaneous coronary intervention [PCI] is over-applied, or something else?

Another implementation:

https://github.com/karlgluck/ThresholdJS

This is a very straightforward encoding of a single 256-bit number.

This is a more interesting take to me than others since it seems you’ve actually learned it?

I see the response later that you’d rather use whatever the team already uses, but could you explain this very strong opinion?

I maintained a 200,000 loc TCL codebase running the front end for millions of lines of industrial C spread over hundreds of machines. It was glorious. After moving on, I’m still struggling to figure out why TCL is so unpopular outside that domain. Other comments seem to boil down to not understanding the language or how to apply it. So what’s your take?

Yeah—as a TCL fan, I agree. Comparing implementations of common coding tasks with other languages doesn’t highlight TCL’s strengths or, really, its purpose.

Personally, TCL fits a niche like QBASIC did. QBASIC was the shortest path from brain -> code drawing on a monitor. Literally 1 line to draw a shape, no initialization and not even an entry point function.

TCL similarly lets you just get on with what you’re doing when you need glue code, GUI’s, and DSL’s. It is easily (even trivially) able to do things that are just a pain in other languages, especially all at once:

- interop with native code (no limits on who calls who or in what order)

- define GUI’s that behave well without it being a huge pain to make anything non-trivial (lookin at you, UE5)

- create novel control flow that feels built-in

- implement an interactive GUI debugger with breakpoints & variable watch in ~200 LOC (saw this once, it’s amazing what you get “for free”)

- save or load a running program’s entire state, including code defined at runtime

- detour any function, allowing you to optimize or patch on the fly

- run from tiny, standalone executables so your users don’t have to install a ton of crap just to run your widget

There’s more but you get the idea. It’s been around for decades for a reason :)

Same. I started building an automated solution for building gamedev environments in VM’s[1] but I can’t help but think there should be a better way.

For years I’ve been pouring through all the apps/platforms like this, but after being burned too many times I am (incredibly) reluctant to tie my second brain to a box that will lock itself unless I pay. Even if it’s just an interface, it’s too disruptive when my whole workflow is upended by a service getting bought/shutting down/“upgrading” to break old features/increases fees.

I see a “free trial”. That plus the landing page not mentioning open source, a permanent license, or common/interchangeable formats bounced me immediately, despite what I’m sure are some great capabilities that folks put a lot of time and work into. Maybe I’m missing something? Is that kind of app not sustainable so we don’t see them, or do I just not know where to look?

That’s what I thought too, until a friend sent me the paper “Class switch towards non-inflammatory, spike-specific IgG4 antibodies after repeated SARS-CoV-2 mRNA vaccination” published a few weeks ago:

https://www.science.org/doi/10.1126/sciimmunol.ade2798

From what I can understand, it seems mRNA vaccines can cause a non-inflammatory response to actual infection that prolongs the disease. I’m supportive of vaccination, but that doesn’t mean side effects can’t happen especially with new technology.

Can someone remind me why Merkle trees of Lamport signatures aren’t the solution for postquantum asymmetric signing? Sure the signatures are huge, but they’re secure unless you can trivially invert the hash function.

Same thing here--I love this keyboard, and have exactly the same issues. I resort to plugging the receiver into the monitor's built-in USB hub which is 8" away. Would love a wired version too, though.

Y’all might also enjoy the GOLEM project: http://www.demo.cs.brandeis.edu/golem/

It’s of a similar age and goals, but evolved physical creatures with a screensaver.

I ran that screensaver as a middle schooler and happened to work with Prof. Lipson at the Computational Synthesis Lab in college.

Like other posters here, I feel genetic algorithms got a bit overshadowed by neural networks. Circa 2010, GA’s were capable of some real feats that still seem cutting edge today: deriving the full set of differential equations of metabolism for a bacteria, self-modeling through exploration, finding fundamental laws of physics by watching a double pendulum video, and more.

A ton of good came out of that lab, including a big part of modern open-source 3d printing (which was originally pursued to print the multi-material GOLEM robots!)

One of my force-multipliers is the Inmotion V5F monowheel [1]

This is among my favorite devices of all time. It is quick, nimble, and lightweight. It has completely replaced walking, a car or a bicycle for my local trips. While there is a learning curve, unlike a bicycle, it has required almost [2] no maintenance in ~4000 miles of riding, and both hands are free to hold things so I can carry much more than I ever could on a bike. I've transported a desk, groceries, a 50 lb box of firewood, gardening tools, and so on. Plus, riding one is just plain FUN: it feels like skiing or flying. You really have to try it to know.

A pessimistic estimate of the V5F monowheel's efficiency:

* Battery = 320 Wh = 275335 calories

* Weight = 12 kg for the device, so with a rider around 95kg

* Range = 20 km on the low end (25-30 km is typical, manufacturer claims 38±3 km)

Efficiency = 275335 calories / 95000g / 20km = 0.14 calories/g/km

An optimistic estimate given my actual riding experience:

Efficiency = 275335 calories / 91175g / 30km = 0.10 calories/g/km
