Maturation killed what is considered innovation in this article. Many if not most of the visually impressive but didactically confusing innovations fell by the wayside. We're currently in a new wave of 'innovation' with LLM-generated summaries and 'helpful' suggestions being added here there and everywhere. Most of those will disappear as well once t becomes clear they do not add real value or once terminal devices - browsers etc - have such functionality built-in using locally executed models which are trained on user preferences (which will be extremely enticing targets for data harvesting so they better be well-protected against intruders).
>But nobody can give you more time.

Yeah they can. That's exactly what someone who does your laundry for you does. They give you that time back, and in exchange for some of your time (in the form of money, which for working people is never anything but time spent doing things other than what you want). If I make $70/hr and can buy an hour of doing laundry back for $20 I can work that hour instead of spending it on laundry, have the same amount of time and $50. Or I can work that hour and buy laundry three times, netting me $10 and 2 hours.
Show HN: CopyCatAI (Solo Dev) – AI Drawing Game That Roasts Your Drawings
Hi HN!

I’m the solo developer behind Drawize (an online drawing & guessing game), and I recently built CopyCatAI—an AI-powered drawing challenge that tests how accurately you can replicate images. Once you finish, our AI judges—Grace Gentle (friendly) and Rex Roast (brutally honest)—grade your work with stars and amusing critiques.

Highlights:
• Single-player or Multiplayer: Draw solo to practice, or jump in with others to see who’s the best copycat!
• Quick rounds: Designed for short bursts of fun or longer sessions.
• Sassy AI feedback: Expect both praise and witty roasts, depending on your replication skills.

Try it here: https://www.drawinggame.ai/

I’d love your feedback—how’s the AI grading, the UX, or anything else you notice? Thanks for giving it a look!
I've wondered whether one can train a child to remember things by recalling things that happened to them repeatedly, but I guess it will create such an induction. And they don't even have language to understand "Remember Monday, 2 days ago, grandma visited.".

And perhaps under a certain age, the brain really has no programming to store anything as memories...
And a stapler - don't forget their document integration!
If you have any way to pull cables between floors, try pulling DAC cables. They give you 10+G, require no splicing (hardware can be found cheap now), and generally just work as you'd expect.

With a 10G backbone, you can get away with basement->main and main->upstairs in a three-floor house, with a small bridge on your main floor.
Sounds awesome! A reliable cross-platform scheduler is a huge time-saver. Love the tech stack choice too!

Just to clarify, the documentation was a bit outdated, but `./cmd -a 1 2 3` would not mean an array of `[1,2,3]` but exactly as you mentioned: option `a` with two positional arguments. And yes! The `--` is supported :-)
I will always have a soft spot for Gatsby, it was my gateway drug into literature. I reread it every few years - the book is almost perfect, and short enough that you can get through it on a lazy Sunday afternoon.
> a malicious server pulling out the signed IdP claims and passing them to another OpenID Connect target

The signed IdP claims aren't a secret. In OpenPubkey, they function like certificate for the user's public key. This makes them useless for replay attacks in opkssh.

The signed IdP claims are also scoped to a Client-ID specific for opkssh, so non-opkssh OpenID Connect services will reject them.
> 2. The post cannot apply to fast/large networks - will be prohibitively expensive.

The expensive parts of fast/large networks are not the fiber strands.

* right of use / lease

* trenching and laying and covering

* amplifiers on long lines

* repair/maintenance

* endpoints

... which is why the first thing you upgrade are the endpoints, and the last you do is lay more fiber. Get the most you can afford (often physically) at the beginning.
Sadly, roots respire- meaning that depletion of the carbon reserves happens by releasing CO2 (in addition to building lignin). It's only when they photosynthesize that plants produce more O2 and absorb more CO2 than they release.
D.C. has plenty of gridlock even without the motorcades. It is one of the worst cities I’ve ever had the misfortune of driving in. Not enough street parking, expensive parking garages, flex lanes that change direction depending on the time of day, and one way streets that don’t alternate traffic direction in any conceivable pattern.

If you go there do yourself a favor and just take the metro.

I trained muay thai before the hysteria, so I was already used to being on my forefoot a lot. It seemed like you had to use your forefoot or you wouldn't be agile enough to avoid injury. So it was kind of odd when other people discovered this.

I also found "barefoot" shoes weird. I used to trail run through rocky forests in leather mid-height hiking boots. As long as the sole is flexible, you can still forefoot/midfoot strike. More specialized shoes are nice, but not necessary.

Looking back, it was the quintessential "secret ancient knowledge that the advanced city-folk forgot"-meme. We didn't forget... plenty of people who needed to run for a living knew about it. It's just that "running" wasn't a thing any normal person did until the 70's.
What do you mean by banner optimization specifically? Ad images and video thumbnails, etc?

In that case, I don't disagree – genAI is still useful for this "side" work like thumbnails, idea generation, and so on. But I don't think it will be used much for content directly, as has been suggested by a ton of big tech companies.

Agreed, one of my favorite pieces of literature. It's what got me into American historical fiction - I later ventured into Steinbeck and Mark Twain, both of whom are masters of the genre.
Using semidefinite programming to find a better taylor expansion in your newton step sounds like crazy talk to me. No way this could ever be practical.

Remember that semidefinite programming is often implemented via the interior point method, which is an application of Newton's method with inequality constraints.

Interesting. That would be great in the basement. I will look into it.
Yeah, it’s nice going for a run barefoot. I feel light on my feet and connected to the ground. When I run in shoes it feels like I have weights attached to my feet in comparison.
Beej's guides are great. As for C, you also need the mandatory companion guide: A Guide to Undefined Behavior in C and C++ (https://blog.regehr.org/archives/213).
I haven't tried a treadmill. I recommend running 50-100m barefoot on solid ground like others have said and seeing how it compares / how your form changes.

I usually run 1-2 miles when I go out, not too much. Just enough to feel all the secondary leg muscles get fired up. Of course if you're new to barefoot running, people recommend starting with short distances.

On shin splints: one trigger was my poor running form. I would lunge my feet forward focusing on getting the longest stride, landing on the heel because my foot was in front of me. It didn't hurt my heel because traditional shoes are so padded there, but the physics/angles/forces of that form are bad. Instead, barefoot runners talk about "falling forward", which is exaggerated imo but gives you the cue that your feet should land under or behind your torso, not in front. This reduces the impact on the feet and legs. Barefoot running teaches this foot placement very quickly. Not sure if that's something you already do or not, but hope it helps.

EDIT - just saw your other comment. Go for a little barefoot run, maybe a few different times, and I think you'll quickly find out where your feet want to go. The "torso first, not feet first" mindset really helped me. (I'm flat footed too, and insoles didn't help me personally; not to yuck your yum, though. Maybe they'll be more comfortable for you)
I have almost the exact same story. I'm not a runner (I was a jogger when I was younger), but my unusually flat feet had me wearing orthotics most of my life, and the podiatrists kept prescribing thicker and more extreme orthotics. Finally, a physical therapist I was seeing (not for foot problems) suggested I try "barefoot" (zero rise, minimal support) shoes, and go barefoot as much as possible, also try to be conscious of using my arch muscles to avoid pronating as I walked.
tl;dr: Haven't worn orthotics since, no more foot problems. My favorite brand is Merrell.
No it doesn't. The headline is ambiguous and you inserted your own biases without confirming they align with the real world.

There’s several with similar dips, at -35 to -60; and several more in -20s.

We've almost come full circle with the idea of "run more cabling" already in some ways.

For example, a building built in 1960 had analog phone lines. Then in the 80s network lines were added. Then in the 90s - 00s more and more and more network were added.

Then in the 2010-2020's we're starting to wind back down. Removing switches and racks that used to be fully populated with CAT5 which are now mostly empty. The end devices that needed these runs are now running on WiFi.
I subscribe to this philosophy.

I recently had my house remodeled. A lot of the walls were opened up and I asked the contractor to run fiber and cat 6a everywhere. Now every room has multiple drops of each. Even the outdoor and garage have several drops. Bathrooms have ethernet. Attic, basement and storage room has multiple drops. I may have overdone it. But, I never wanted to every worry about this ever again.
I like writing dialogue. AI gives me some idea of how another person would respond. It does rhythm and wit very well. But it doesn't understand phonetics. It writes dialogue like a 16 year old, enthusiastic and amateurish.

I like riffing off AI's creativity. It gives me creative ideas for scenes and conflicts, and I carve whatever it gives me into something pretty, like a lapidarist.

Also AI helped in writing an engine for it - things like VNs don't normally allow for the pacing of good dialogue. So I had to do something to allow for a little back and forth, interruptions, change of tone, etc.

Yes, but that's not something you can beamform away with a planar array. Especially if your goal is to record what's going on behind the screen. You need something out of plane. Which they may have had! I don't know the details of the hardware.
We've had good luck with Mosquito Dunks, both in natural standing water sources and in dedicated "trap buckets" filled with water and vegetation, but you have to do it early in the season as the dunks only affect the larvae.

Last year I came across a water-filled stump that was teeming with larvae swimming around in it. Dropped a piece of a dunk in, came back 24 hours later and the water was clear.

Many years ago, the National Lampoon guys brought out some magazine parodies. I think that it was the Newsweek take off that recast the Soloflex ad as Cruciflex, with the motto: No pain, no gain. But then you discovered it was the pain you really wanted.
Medicine is even more weird with titles. At least in the UK if you get qualified people call you “Doctor” unless you’re a surgeon in which case you are called “Mr/Ms/Mrs/Miss/etc” unless you are a professor which some consultants are in which case it’s “professor”. But if you work in medicine and call a consultant surgeon “Dr <whatever>” they will actually correct you.

Browser extensions kind of suck. I personally prefer native apps and apps built out of the browser (otherwise I'd just get a Chromebook). Whenever I think about web apps I think about my time at a large firm where the goal was to eliminate employee laptops to save money and instead roll out virtual desktops. It was always a worse experience, though certainly had clear areas where it could be improved. I think of web apps the same way, they seem like the nice and easy solution but for some reason they tend to just kind of suck.

I figured that the best way to own a ranch is to start a successful tech company, sell it (or parts of it), buy a bunch of ranchland, and then hire ranch hands that always wanted to get into the business but didn't have the capital for it.

That seems to be what all the tech billionaires do. Gates, Bezos, and several old-line tech company heirs are all big ranch holders.

A single mic facing in both directions, or one mic next to the other but facing opposite directions, doesn't really help. You need separation between them in the direction of wave propagation (so in the front-back dimension of the laptop screen in this example) to tell which direction the sound is coming from.

> These are women who wanted the baby

That's an interesting point. I haven't interviewed an extensive number of post-abortive mothers, so my view is, of course, not representative of the whole, but in those few cases I have (via my community work), this was universally true. In every case, there were external factors pressuring the mother to abort the baby despite her motherly instincts pushing back on it at every level. Sometimes, it was a controlling boyfriend, parents, or some other peer pressure. In each case, though, the mother was left scarred for life.

I wish more people would openly talk about this.
There was probably a core of 50 people mainly responsible for these (with hundreds of thousands in awed aspiration/inspiration) who've since retired or moved on to other interests or got distracted by politics in the meantime after 2016, or any other similar reason. It was probably Mike Bostock's departure from the scene in 2017 that was the core catalyst.
Interesting look at some of the details of The Great Gatsby that connect to World War I, and Fitzgerald's own history with the war.

The museum that published this is quite good, though sadly a bit out of the way for many on this site (Kansas City). It's easily reachable with public transit if you're ever there and staying near downtown.
Mode is simply the wavepattern of the light traveling through the optical fiber. Multimode means there are a few different wavepatterns traveling down the fiber, they tend to potentially interfere and its not as efficient of a use of optical power. In singlemode, this is a lot harder to do and requires better optics, the light is in one pattern, power is efficiently allocated to that pattern, and thus the light can be sent much further. Its been many years since college so hopefully that explanation suffices.

Now lets say you want to send multiple signals to get more bandwidth on one fiber, you just need to move the frequency/wavelength of light so different signals have different wavelengths and can be discerned at the receiving end. That's gonna take even more optics and filters on both ends, but works quite well to add more bandwidth to existing fiber installations where running more fiber would cost a lot more than installing new equipment on the ends.

It's a little bit of inside baseball, but it's been interesting to watch the article's author, Fred Lambert, change his tune about Elon Musk over the years.

I'm a car guy so I've been following automotive electrification for a while, and in the earlier days, Electrek was a shameless Tesla fan blog. I occasionally followed a link and ended up there and felt like I was reading the thoughts of someone fully enveloped by Musk's reality distortion field. Lambert was an early investor in TSLA from the sound of it and just raved about Tesla cars and gushed about Musk.

Anyhow, I think it was the repeated moving of the goalposts for Full Self Driving, or maybe it was the Roadster 2.0 delays, or maybe it was the unhinged Twitter rants ... but anyhow, Lambert slowly became more critical of Musk (until the 2 had a falling out on Twitter), and Lambert now writes things like:

> Call me crazy, but I think the company would fair better with a competent full-time CEO instead of an egomaniac wannabe oligarch who consistently lies to shareholders, engages in resource tunneling with his private competing company, and is deeply lost in one of the worst cases of social media addiction that I’ve ever seen.

It should, opkssh just creates ssh public keys. The integration tests don't current cover that case so I created an issue to add that to the integration tests:

To elaborate a little bit;

I've been in many, many buildings for cabling issues. While I generally agree with your assessment of "run more everything" I think this could be taken out of hand for a lot of smaller IT departments who aren't capable of using more advanced methods of network building. Like subnetting, VLAN trunking, or redundant links.

Why would you need to learn about these things if you've got 3 or 4 more pairs of fiber hanging down? Then you have a situation that I've seen before, where you have 2 fiber runs carrying flat networks right next to each other with just a couple of IP phones on each one.
Scroll something useful – mindful content discovery
i wanted to share something i've been working on lately. "scroll something useful" is a different kind of scrolling experience designed to make your screen time more meaningful.

unlike typical social media where you endlessly scroll through random content, this app serves up curated topics that hopefully add value to your day.

you can discover new topics, and get recommendations for further reading. it's basically scrolling, but purposeful.

i'd like to know if this sounds like something you'd use. the next step is to automatically personalize recommendations based on your interests
Street parking causes much of the traffic because people double or triple park or drive around endlessly trying to find a subsidized spot. The problem DC has is simply that too many people are trying to go to the same places, and there just isn’t that much room for cars, especially with the limited river crossing points and reserved federal space.

I think we should stop glorifying Heaviside for his short sighted view on the usage of quaternion for EM field that he considered it as unnecessary "evil" [1]. He then developed a crippled version of the unintuitive vector calculus, a mathematical hack that some people still considered it as the golden standard for doing EM calculations.

IMHO by doing this and going against quaternion he has hindered much progress in EM for more than century since that's what being taught in textbook, and most people including EM engineers don't care to look what's available beyond the run-of-the-mill textbooks.

There's a very famous saying by Einstein, make it simple but not simpler, and in this case Heaviside's "Vectors Versus Quaternions" paper and related advocacy has caused more harm than good to the math, science and engineering of EM based system by doing simpler than simpler (pardon the pun).

I have also a hypothesis that perhaps someone can research into, if Einstein is exposed properly to quaternion based EM, and using it he would have solved the general theory of relativity much earlier than he took of 10 years after the special relativity discovery. The quaternion form of relativity has been even presented by L. Silberstein in 1908, just three years after the discovery of special relativity [3].

It is a shame that even today apparently the Wikipedia entry of both special relativity and general relativity do not even mentioned quaternion (zero, nada, zilch) as if it is a taboo to do so, perhaps partly thanks to Heaviside of his seemingly very successful propaganda even after more than century of progress in math, science and engineering.

He lifts things.
The C# "source generator" approach is a good compromise; it runs within the build chain so has the ease-of-use of macros in that respect, but they don't need to be written in a weird macro language (they are C# or can call external tool) and when you debug your program, you debug through the generated source and can see it, more accessible than macros. Not sure if there is something similar in C/C++ integrated with the common toolchains.

But when working outside C/C++ I've found myself missing the flexibility of macros more times than I can count.
A lot of people take issue with the Apple Developer account fee, but it’s really not that bad. To put it in perspective, at $99/year it comes out to just over $0.27/day. That’s a pretty cheap hobby. I certainly spend way more than that on my woodworking hobby.
