And photography initially had lower quality and performance ceilings compared to portraitists and artists of the day. And today, photographers win awards for their work.

New tools and techniques that lower the barrier to entry always get over used, over hyped and bring in masses of people making everything from impressive new things to absolute cheap garbage. And then people learn the limitations, the tools get better and a lot of people stop using the tools because they realize there are still skills that go into the process and they aren’t interested in learning those skills. The tools find their place, and new masters rise into the new world. And then a new tool is created and we start the process all over again.

Then there's needing to contend with possible serial number scanning occurring at automated stations and at financial institutions, cataloging the movements of specific bills, detecting clones (improbable or impossible physical note appearances), and detecting zombies (decommissioned/known-destroyed numbers, and numbers never emitted). Randomly generating numbers is likely to trip clone and zombie sensors at various surveillance points.

Bill scanning to verify authenticity is already occurring, why not record the fact Bank of xAI ATM #67387 tendered two Franklins with serial numbers $SERIALA and $SERIALB to you (verified by PIN and card, and possibly bolstered by Face ID incognito); maybe older systems only do the verification locally and lack OCR, but I'm positive new systems are plenty powerful enough to run pared down OCR on serial numbers... wait they have been doing it with cheques all these years with handwritten dollar values, so why not OCR serial numbers coming and going? You see? The net deepens. I probably can't suggest methods of washing this data without possibly committing some obscure crime, so I will leave you to your creative imaginations...

The "peripheral area of the retina continuously contacts sunlight" part is just wishful thinking at this point. Every company in this space except Xreal has abandoned the idea of a see-through display, and Xreal has only kept it because their focus is on weight and comfort over features and it lets them avoid needing passthrough cameras and everything that goes with them.

> I'm glad that El Salvador has taken control over gang activity

> Abrego Garcia’s family has had no contact with him since he was sent to the megaprison in El Salvador, known as the CECOT. His wife spotted her husband in news photographs released by Salvadoran President Nayib Bukele on the morning of March 16, after a U.S. District Judge had told the Trump administration to halt the flights. “Oopsie,” Bukele wrote on social media, taunting the judge.

The man is nothing more than a tyrant with a smile, and now his concentration camp will be used to house whoever pays him or gets in his way, not just alleged gang members. He's already in power unconstitutionally: https://apnews.com/article/el-salvador-elections-bukele-demo...

Now it may take decades for Salvadorans to rid themselves of this dictatorship.

The South China Morning Post reports that he was fired by Indiana U after letting them know that he was moving to Singapore in the summer.

So he gets fired, goes away on a vacation or whatever, and the govt starts investigating him of malfeasance?

Well, my experience with an IBM operators console was back in the mid-80s with a twin 4381 setup. It was sometimes more convenient for me to set up a big print job at the main site which had a high performance printer (I actually wrote a multi-site print spooling service in ReXX earlier, but it was more efficient for big jobs (ha-ha for UK readers) to execute them directly).

Anyway, my experience - I am in Linda's office - Linda (system manager) is not in yet, the system console is just convenient:

Me: set up job, using normal keyboard commands, with my usual login, no special privileges.

Linda: (just comes in) What you doing?

Me: Don't get your knickers in a twist. And can you make me a coffee?

Linda: Aargh! OK (we were friends), but don't press Button-B!

One of my many problems with function keys. Button-B would probably just have requested an operator to unmount a disk (or whatever), but who knows.

I hate compiling. 9/10 something goes wrong. Sometimes I can fix it, other times I just abandon the effort and use something else. These days I just use packages or docker images and if that doesn't work out I'm moving on, ain't nobody got time for this. You really can't expect people who just want to use their computers and don't even know what a compiler is to get involved in a process like that.

Adding some context to this, because it's a really interesting read that's worth the time if you ask me: it's about how some recently 'discovered' early playtest versions of Pokemon cards were found to be fake, or at least very suspicious, based on the presence (and decoding) of these dots.

I also find it interesting because the person who posted the discovery and breakdown of the dots stood to personally lose thousands of dollars they'd spent on the fakes, but posted their findings anyway.

Intel mostly just shot itself in the foot; easy to "outperform" a handicapped opponent, and there is no merit in doing so. x86 is also a piece of shit in the grander scheme of things, and will be eaten away by alternative hardware soon. So no, I don't think that has anything to do with it, which is why I was asking a legitimate question. Do people just regurgitate the crap they read online, or do they actually put thought into the beliefs that they form?

Agree with your last statement, though. For-hire CEOs--as opposed to founder-CEOs, who often have an actual vision--take way more credit for their "work" than they deserve.

Also rofl at that "axe to grind". That one took me offline for a few seconds.
Show HN: AI Job Matching Tool to help in this difficult job market
by kbeqiri14 | 2025-04-02 01:26:31+00:00
Hey all - built this AI job matching tool on the side (am somewhat technical but used Cursor and Replit to get an MVP going). Was laid off and have been having a tough time finding jobs (honestly the job market is so difficult right now and applying to jobs is a crap shoot)

Here is how it works:

--Recruiters can post a job similar to other job boards. The AI agent operating underneath the hood analyzes the job description and other specifications.

--Afterwards, the agent goes through the database of candidates to find the best fit for each job by analyzing each applicant's previous experience and future job preferences (e.g., level, role, location, salary, etc.), assigning them a score of 0-100%.

--The agent then presents recruiters a stream of higher qualified candidates with match scores above 80% for each job posted that they can swipe "interested" or "not interested." Candidates also get a stream of jobs that they are 80%+ matches for.

--Once a match occurs, recruiters can sync their calendars and candidates can choose a time to chat about the role (basically get a 1st round interview).

This is still in beta, so would love to get feedback. Here is a demo of what it would look like

The original version was the four (SMB1,2,3 and Super Mario Bros. USA aka the western SMB2) 8-bit Super Mario games ported to the 16-bit Super Famicom. New graphics, sound, etc.

Super Mario 3D All-Stars was Super Mario 64, Sunshine and Galaxy ported to the Switch with HD graphics and limited modifications. Widescreen and new controls were added.

The 3D version was a limited edition thing and not terribly well received. They could have done a lot more, they also could have included SM Galaxy 2.

Nintendo did a similar thing for Zelda on the GCN with a couple N64 games on a disc when you preordered a newer Zelda game.

You wanna hear my evidence-free cosmic structure theory? Of course you do.

If you shine a laser through a mass of soap bubbles it will unsurprisingly split into lots of smaller beams due to a mix of refraction and reflection. I have long held the suspicion that there's an isomorphism between gravitational and surface tension structures, that the multiplicity and distance of galaxies may be somewhat illusory, and that many of them are translated/rotated reflections of nearer ones. Laugh now, perhaps gasp in wonder later.

>the newness of different tech isn’t actually the real problem and feels like the wrong critique

I'm not equating new = bad. I'm saying new = good is wrong. And based on your last sentence, you do think car manufacturers all switching over to all touch controls was a problem. Almost everyone prefers buttons to touch screens, that's my point. The better more popular option was rejected because of a false premise, or false belief.

This is exactly the goal. It was a little difficult to do, so I just postponed it.

TLDR; Apple devices scanning in the background require a lot of workarounds [1].

Another comment suggested proposing this to Apple [2]. If this were built by Apple internally, it would be game-changing. A little delusion never hurt anyone :seenoevil:

This blows my mind, that in 2025 we still struggle with a simple task such as "read in a string, parse it, and query a cascade of resolvers to discover it's IP". I just can't fathom how that is a difficult problem, or why DNS still is notorious for causing so much pain and suffering. Compared to the advancements in hardware and graphics and so many other areas.

As a non-developer, I find it difficult to step into the self-hosting world. What I recommend for people like me is the service PikaPods [1], which takes care of the hard part of self-hosting.

I have now switched from some SaaS products to self-hosted alternatives:

- Feed reader: Feedly to FreshRSS.

- Photo management/repository: Google Photos to Imich or Imgich (don't remember).

- Bookmarks: Mozilla's Pocket to Hoarder.

And so far, my experience has been simple and awesome!

At my old uni there were a couple public terminals running DOS, most of the time sitting idle at the prompt. It was bespoke kiosk cabinets only exposing keyboard and screen. One April Fool's I had the bright idea to change PROMPT to something along the lines of "This terminal out of service." - and to increase the confusion, also to change PATH to a non-existent directory, so that most commands wouldn't work and instead flash "Bad command or file name.".

For a couple minutes observed people coming up to a terminal, trying a few things, and stepping away in frustration.

I sure hope administration did restart the terminals overnight to return regular function; normal users were unable to access the power & reset controls.

Decades ago, I came up with 'micro-kerning' - an added single length gap added to few scattered letters = unique message for each person you send it to. True, you have to keep an index to compare to ID the leaker. Various governments used to do this for this reason in the last few years of the 1980's. Smart people used to copy/paste with a constant width font to defeat this. Then locked pdf helped, but OCR got around this. I think you can use steganographic encoding of scattered dots in a jpg, which laser printer catch money copiers with these days. The dots can be found with a scanner and again needs an index to 'read' the color photo. I have a friend who was an ambassador until he retired = I will ask, but he might consider it sensitive, and not reveal it - likely?

Agent-based modeling offers a more realistic approach to economic systems than traditional equilibrium models. New approachs including generative agents (ABM+LLMs) are promising. J. Doyne Farmer's recent book "Making Sense of Chaos: A Better Economics for a Better World" is a great reading for those interested in this field.

For those that have not implemented toposort or don't remember it: 1) only directed graphs without cycles can be topologically sorted (DAGs) 2) there can be more than one topological order and 2) reverse post order of depth first traversal from every unvisited node shields a topological order.

In JavaScript:

function toposort(graph = { a: ['b', 'c'], b: ['d'] }) { const order = []; const visited = new Map(); function dfs(node) { const status = visited.get(node); if (status === 1) throw new Error("Cycle found."); if (status === 2) return; visited.set(node, 1); // In progress. const adjacent = graph[node] ?? []; for (const neighbor of adjacent) dfs(neighbor); visited.set(node, 2); // Done. order.unshift(node); // Reverse post order. } for (const node in graph) { if (!visited.has(node)) dfs(node); } return order; }

Myst is one of my favorite games, but I never could get into realMyst. The idea was great at the time, but I thought the visual fidelity was lower (despite being ... "real"), and the click-based movement never played well.

I did like Real Myst: Masterpiece Edition a lot (though it ran terribly on my powerful-at-the-time system). But I'd argue for the OP to play Myst: Masterpiece Edition first. IMO the interface is just as important to Myst as everything else.

With regards to the first one described the TDK with the UV guard, I am curious as to what that is. My guess is it has more to do with avoiding UV related damage than blocking UV.

I am not sure the authors spectrometer test(which was very cool, avidly reading that series of articles right now) would reveal anything as polycarbonate is naturally quite opaque to uv light.

https://en.wikipedia.org/wiki/Polycarbonate#/media/File:Visi... Note how the transmission is dramatically reduced once past violet.

Fun fact ordinary clear polycarbonate eyeglasses do just as good a job as sun glasses at protecting your eyes from uv.

> 1. For the consumer, paying off the balance due at the last minute gives you an interest-free loan on your spending for an average of 6 weeks. Let's say you spend $1000 per month. At 5% interest, that saves you about $30 a month.

Saves you versus... taking a 5% loan for the 6 weeks? You need to actually invest the money versus paying the credit card to earn interest. The average consumer is not walking around picking up pennies in front of a steamroller trying to get $30/month with clever interest rate arbitrage.

> Not many people seem to understand the time value of money, certainly it isn't taught in school

Realistically a person will take out loans for like 4-5 transactions in their life where this actually matters. House, car, student loans, maybe a small business. If you look at personal finance advice they usually use the "snowball method" of simply paying down the highest-interest debt first and reducing expenses.

> It can also be improved; I know BLE is not _that_ effective under rubble.

It's a tough problem to solve because you're up against the laws of physics and the very boring (and often counterintuitive) "Antenna Theory". Bluetooth is in the UHF band, and UHF isn't good for penetrating anything let a lone concrete rubble.

To penetrate rubble effectively you really want to be in the ELF-VLF bands, (That's what submarines/mining bots/underground seismic sensors use to get signals out).

Obviously that's ridiculous. Everything from ELF to even HF is impossible to use in a "under the rubble" situation because of physics[1]. Bluetooth (UHF) might be "better than nothing" but you're losing at least 25-30 dBs (which is like 99.99% signal) in 12 inches of concrete rubble. VHF (like a handheld radio) can buy you another 5 inches.

Honestly I think sound waves travel further in such medium than RF waves.

[1]: Your "standard reference dipole" antenna needs to be 1/2 or 1/4 your wave length to resonate. At ELF-VLF range you need an antenna that's 10k-1k feet long. You can play with inductors and loops to electrically lengthen your antenna without physically lengthening it, but you're not gonna get that below 500-200 feet. The length of a submarine is an important design consideration when deciding on what type of radio signal it needs to be able to receive/transmit vs how deep it needs to be for stealth.

Just as we have weather forecasting, climate models .. we do need and should have good fine-grain computational models of complex systems such as the cell .. and the global economy.

We should be able to have whole economy simulations give reasonable predictions in response to natural events and lever-pulling such as :

- higher progressive tax rates - central bank interest rate moves - local tariffs and sanctions - shipping blackades / blockages - regional war - extreme weather events - earthquake - regional epidemic - giving poor people cash grants - free higher education - science research grants - skilled immigration / emigration

But .. of course this would require something like a rich country providing grants to applied cross disciplinary research over many years.

It might even lead to insights that prevent semi-regular economic boom and bust cycles we experienced the past 100 years.
