I won't take acetaminophen (usually) learning of the liver toxicity and low overdose potential. And I have a friend that destroyed his kidneys with ibuprofen and is on a transplant list.

But from what I understand acetaminophen also dulls emotional pain like from being fired or breaking up with a girlfriend which is interesting.

I still prefer to take neither if I can avoid it and I'll hurt a little bit instead. Hurt a lot and I'd probably change my mind though.

Check with your local non-profits, most 2nd hand no warranty/guarantee shops are in your local small industrial parks and sell mostly to non-profits or very small companies.

They will not have a store front or advertise you'll just call the owner and ask if they have "X" or equivalent and if so you can go get it. I've used a few of them over the years for monitors and wyse terminals for small businesses.

Like many things in this regime, it's not about the stated goal. Just as with the "flood the field" strategy they use, it's about setting precedent and normalizing the US military being deployed domestically while moving too fast for the media and watchdogs to keep up.

Their end goal is the death of Posse Comitatus. Let's watch the flow:

- Deploy to California, "justified" by protests. But it's okay, we won't make arrests.

- Change orders to make arrests.

- Deploy to DC, justified by vague "crime". But we won't use lethal force. And it's not a state, so no PC issues.

- Mandate lethal weapons.

- Deploy to "friendly" states, justified by nothing. But, it's okay the governors have to consent.

Trump, being himself, has already given away the plot. From here, they continue to desensitize their own base to military deployments within our homes. They crack down more in blue cities within the red states, then use any resistance as justification. Then they expand to "less cooperative" states.

There must be a huge push end of year.

>How many games do you imagine can be released per day even with the help of current Sota LLMs ?

Given the number of people who want to make games—if code is the bottleneck, and LLMs can really make you hugely more productive, I’d expect to see an actual explosion.

My experience is that neither of those assumptions are true though.

Any language running on the JVM (Java, Kotlin, etc.) and CLR (C#, VB.NET, etc.). As long as you don't compile directly to native code and you aren't running in a locked-down environment where codegen is disabled, you can generate code at runtime and execute it alongside existing code.

For example, there's java.lang.reflect.Proxy [1] and System.Reflection.Emit [2].

The new top of the line CPU might only cost $500, but even if you have a Framework laptop with replaceable parts, the new top-of-the-line mainboard is going to cost you north of $1k. If you don't, you're probably talking about a new $2k+ full laptop purchase.

And I don't want a desktop.

But I would agree that, when you are purchasing that new laptop (or mainboard), you get the best that you can afford. Pushing your upgrade cycle out even just one year can save you a lot of money, while still getting the performance you need.

Hello everyone, I'm a solo developer with a deep passion for personal finance.

I built GlanceBook because I found it difficult to get a clear overview of my money. I noticed that many existing finance apps, while powerful, have become quite complex over time, creating a steep learning curve for new users. I wanted to create a simple and intuitive way for people to manage their money, with a focus on helping you understand your financial life "at a glance."

GlanceBook is a small project, and I'm at a stage where I need your honest feedback to make it truly useful for everyone.

Here are the core features currently available in GlanceBook:

Instant Monthly Insights: The main screen gives you a clear overview of your income, expenses, and balance. It also highlights your top 3 spending and income categories with a visual graph, so you know exactly where your money is going.

Effortless Transaction Entry: No more typing categories. Just tap to select from a list and use the built-in calculator to enter amounts quickly.

Visual Data and Custom Calendar: Dive deeper into your spending habits with detailed graphs that show monthly totals, transaction counts, and the share of each category. Our custom calendar makes it easy to track and review your daily income and expenses.

I am also planning to add these features in the future. What are your thoughts on these ideas?

Smart Budgeting Tools: I'm planning to add the ability to set a budget for any category (e.g., 'Groceries') and visualize your remaining balance in a real-time pie chart. The app could even send "risk alerts" if you're close to exceeding your budget before the month ends.

Simplified Transaction Flow: I'm considering streamlining the process of adding transactions. Instead of a single screen, you would enter the amount and date first, then move to a second screen to select the category and location, with an option to add notes or photos.

Your feedback is truly valuable to me. Do you think these planned features would be helpful for your financial life? Please feel free to ask me anything about GlanceBook. Thanks so much for your time and support!

I don't think that's people who refer to Tyranny of Structurelessness mean.

At least I read it more as that you can't just declare 'there be no hierarchy here' and be done. Unless you carefully engineer the system, the implicit hierarchy will reclaim the void and, all else equal, an implicit hierarchy is harder to undo because it isn't supposed to exist.

In political terms: if all you do is kick the ruler out, you may get a corrupt patronage network instead of democracy. Actual equality doesn't come from just the absence of strong explicit hierarchy; it requires proper institutional design.

Hi HN,

I built Beelzebub, an open-source framework for honeypots designed for those who want to safely collect and analyze attacks without sacrificing realism. TL;DR: low-code (YAML), multi-protocol (SSH/HTTP/TCP/MCP), LLM integration to simulate realistic system behavior while keeping a secure low-interaction architecture.

Why I built it ?

- High-interaction honeypots are realistic but risky and expensive to maintain.

- Low-interaction honeypots are safe but attackers can spot them easily. Beelzebub tries to strike a balance: it leverages LLMs to generate convincing, dynamic responses while running on a fully controlled backend.

What it offers today:

- Low-code configuration via YAML, modular and easily extensible.

- LLM integration (OpenAI or local models) to create honeypots that talk back like real systems.

- Multi-protocol support: SSH, HTTP, TCP, and MCP (useful for catching prompt-injection attempts against LLM agents).

- Ready for production with Docker, Kubernetes, and integrations with observability stacks (Prometheus, ELK).

Why give it a star and an upvote:

- An upvote here helps more defenders and researchers discover it.

- A star on GitHub helps the project grow (visibility, contributors, integrations). If you try it and like it, please the repo and share your feedback!

Thanks for reading, if you’d like me to post a case study or benchmark showing how it performs against real-world attacks, let me know!

The main topic here was Swift vs Android's Java.

Of course with manual memory management you may be able to write more efficient programs, though it is not a given, and comes at the price of a more complicated and less flexible programming model. At least with Rust, it is actually memory safe, unlike c++.

- ref counting still has worse throughout than a tracing GC, even if it is single-threaded, and doesn't have to use atomic instructions. This may or may not matter, I'm not claiming it's worse, especially when used very rarely as is the case with typical c++/rust programs.

> You also only need to atomic increment / decrement when ownership is being transferred to a thread

Java can also do on-stack replacement.. sometimes.

- regarding lower level capabilities, java does have an experimental Vector API for simd. Atomics are readily available in the language.

- Java's memory model only requires 32-bit writes to be "atomic" (though in actuality the only requirement is to not tear - there is no happens before relation in the general case, and that's what is expensive), though in practice 64-bit is also atomic, both of which are free on modern hardware. Field acces is not different from what rust or c++ does, AFAIK in the general case. And `synchronized` is only used when needed - it's just syntactic convenience. This depends on the algorithm at hand, there is no difference between the same algorithm written in rust/c++ vs java from this perspective. If it's lockless, it will be lockless in Java as well. If it's not, than all of them will have to add a lock.

The point is not that manual memory can't be faster/more efficient. It's that it is not free, and comes at a non-trivial extra effort on developers side, which is not even a one-time thing, but applies for the lifetime of the program.

I neither know nor care what the C-suite at my company thinks, as long as they provide me the resources necessary to get my job done effectively.

And, so far, it seems like they are fairly understanding, as they are happy about the output of my work. After all, they aren't paying me per-line-of-code delivered, they are paying me to solve problems. If they think that an LLM can replace me fully, they are more than welcome to try it and see how it works out for them.

The entirety of my report chain is just former engineers (with some of them being pivotal to things like GMaps SDK for iOS and such), so I am not really worried about them testing this theory out in practice. And if they do and decide that an LLM can replace me, well, there are always other jobs out there I can take. From my personal experience at this company, I will be just fine.

Yeah I had to wait years to really use Parquet effectively in Python code back in the 2010s because there were two main ones (Pyarrow and Fastparquet), and they were neither compatible with either other nor compatible with Spark. Parquet support is much like Javascript support in browsers. You only get to use the more advanced features when they are supported compatibly on every platform you expect them to be used.

> I think it is just us getting old.

I don't think it's that. I've used Linux since high school as well and use Mac occasionally and I get the same feeling that Mac is weird and nonsensical.

The reason I'm pretty sure it's something intrinsical to Mac and not age, is that is that I also use Windows now and then and while I don't like it and I have lots of complaints about it, I find Windows in general does make more sense to me then Mac. It's just crappy and clunky and closed, but it's generally pretty straightforward.

And I've had people tell me that since Mac is unix compliant it's very similar to Linux but I've never found that to be the case. Mac in general is obtuse, poorly documented, rarely configurable, and I always get the impression they like to do everything based on some weird sense of aesthetic that they've cultivated over the years that seems to work for people fully invested in the Apple ecosystem but just makes no sense to anybody else.

PCA (essentially SVD) the one that makes the fewest assumptions. It still works really well if your data is (locally) linear and more or less Gaussian. PLS is the regression version of PCA.

There are also nonlinear techniques. I’ve used UMAP and it’s excellent (particularly if your data approximately lies on a manifold).

https://umap-learn.readthedocs.io/en/latest/

The most general purpose deep learning dimensionality reduction technique is of course the autoencoder (easy to code in PyTorch). Unlike the above, it makes very few assumptions, but this also means you need a ton more data to train it.

For code no, no shame as long as you understand it and agree. For internet comments or blog posts or emails ya, shame. In my opinion.

But I'm a native English speaker and (I think) a decent writer. But if I had to write something in another language I was only marginally fluent in I'd probably reach for an LLM pretty quickly.

AI prose has been mediocre since the release of ChatGPT. My layman's interpretation is there's just no strong creativity / humor / etc signals to train on, as compared to say math or coding. Current models are "smarter" so when asked to produce eg a joke they think harder, but the end result always misses the mark just the same.

Also, latest Oracle version (23ai) has added "concurrent on-commit fast refresh" functionality, where concurrent transactions' changes are rolled up to the MV concurrently (previously these refreshes were serialized).

https://oracle-base.com/articles/23/materialized-view-concur...

From the article: "Concurrent refreshes will only happen if there are no overlaps in the materialized view rows updated by each session."

Excellent explanation. I could add, typical Thermal Electric Station (Gas or Coal) could have significantly larger working temperature than Nuclear, because more strict safety measures for Nuclear on nearly same level technologies.

For example, Nuc typically don't cross 400C, when Gas/Coal could work on 450C or even more.

Plus, non-Nuc could use some more exotic technologies, like MHD (magnetohydrodynamic) generator, to provide much more efficiency of power generation, or CO2 turbine to make installation much smaller. (Theoretically, somebody could build Nuclear MHD device, but it will not pass safety restrictions).

Are you building the Debian kernel with the same .config as when you build the kernel directly? If not, that's probably why. A Debian kernel build will build basically everything, mostly as modules. A kernel tailored for your specific hardware and needs will be much faster to build.

Also disabling building the _dbg package for the Debian build will significantly speed things up. Building that package takes a strangely long amount of time.
HeartWatch: A Proactive Child Safety System
by Richard_Damge | 2025-08-24 20:42:58+00:00
Overview HeartWatch is a real-time child safety monitoring concept that combines biometric heart rate data, GPS tracking, and ambient audio into a single, proactive system. It's designed to help parents, guardians, and institutions detect early signs of distress or danger in children and respond with speed and confidence.

Core Features Proactive Heart Rate Monitoring Integrates with a wearable device (smartwatch, band, etc.) to continuously monitor a child's heart rate. The app uses advanced algorithms to recognize patterns that indicate fear, panic, or physical distress, triggering immediate alerts for the guardian.

Live GPS Tracking with Geofencing

Provides live, real-time location tracking. Guardians receive instant alerts when a child enters or exits predefined "safe zones" such as home, school, or a designated play area.

Ambient Audio Capture

When a heart rate anomaly is detected or a geofence is breached, the app can automatically and securely record a short audio clip. This feature helps guardians assess the situation by capturing potential verbal distress or threats in the child's immediate surroundings.

One-Tap Emergency Response

In an emergency, guardians can instantly forward the child's live location, biometric data, and any captured audio to emergency services with a single tap. The system could also include an optional panic button on the child's wearable for immediate alerts.

Privacy and Security

Privacy is at the core of the design. All features are strictly guardian-controlled. Audio is only captured in response to a potential threat, and all data is secured with end-to-end encryption.

Target Users: Parents of children aged 4–14. Guardians of children with health conditions or anxiety. Schools and daycares seeking an advanced safety tool. Child welfare agencies and programs for at-risk youth.

Potential Integrations & Future Directions:

Integrate with existing wearables like Apple Watch, Fitbit, and Garmin.

Develop a custom wearable specifically designed for children (e.g., the "HeartWatch Band"). Expand to other biometric data, such as skin temperature or stress levels.

Declaration of Free Use: I release this concept, HeartWatch, into the public domain. Anyone is free to build, adapt, or deploy it in part or whole — with no need for permission, credit, or compensation. My sole intention is to see this concept applied to enhance child safety and preserve lives. HeartWatch: A Proactive Child Safety System by Richard Damge is marked CC0 1.0.

> Coding is a hard part of game dev. Coming up with interesting novel mechanics or plays on known genres is rather easy but bringing them to life is hard esp the code. Multiplayer vampire survivors but with giant battletech mech customization.

I disagree. Sure, it's hard, but it's much harder to come up with novel and fun gameplay ideas. Once you have the fun idea, it's just a matter of splitting the problem in bite-sized chunks and iterating.

There is no methodology when you are faced with the dreaded blank page problem and need to come up with something out of nothing. Maybe going for a walk helps. Maybe taking a heroic dose of drugs. Maybe trying a few different things and see what sticks. It's a problem that has existed for millennia in all creative endeavours; whereas coding is "just" engineering.

I've been learning game dev the past month, had to learn a ton of maths to do anything, which was still easier than the question "what kind of game do I want to make?" which is still, to this day, unanswered. No 3Blue1Brown video is gonna help here, unlike learning how to do vector maths and what the hell is a quaternion.

it's a brilliant title that's both technically correct and extremely misleading!

I thought it implied that there was an ongoing legal battle over the home and some original will that upsets those proceeds had been found underground. That'd be a very dramatic story!

Instead, there was a legal battle long in the past, and this was the will that was submitted to the government at the time, and kept in the archives. They make no mention of whether Shakespeare's original will survives. It's basically hey look at this document from the old archives that somebody thought was might be of historical value so they put it in a box but really doesn't change anything. It's just available online for the first time.

> No one likes hearing hypocrisy from politicians

Cambridge Analytica showed politicians in real time that on a population scale, hypocrisy doesn't make any difference. In fact people will bend themselves around to square the circle.

Politicians finally knowing for a demonstrable, data-backed, evidence-based fact that they can do basically whatever they want and keep their support as long as they just say they right things is what has brought us from 2016 to now.

My advice is to search for the stuff you want on eBay, then filter results for sellers near you, identify some interesting sellers and try to visit their facility in person. If you buy through eBay, then a less awkward tactic is to choose "Local Pickup" instead of a delivery service. When you're at the facility, ask if you can take a look around or if they know of other sellers for used server equipment.

The " (UK)" appendix roughly indicates who would come to protect them in case somebody else tried to invade.

The channel island Jersey, for instance, more correctly "The Bailiwick of Jersey", is an autonomous and self-governing island territory of the British Islands. It is a British Crown Dependency with an independent local gouvernment, but not a sovereign state.

The relationship the iPad had with tablets already in the market was basically the same as the PalmPilot vs. existing PDAs in 1997.

There was the big expensive Newton, and chunky Windows CE devices with keyboards that looked like micro-laptops. The Palm initially felt more like a toy compared to them, and it never got all the features of the Newton for example.

2 things:

1. My brothers (I have a number of them) mostly work in construction somehow. It feels most of them drive a VW Transporter, a large pickup or something, each carrying at least $30 000 in equipment.

Seeing people I work with get laptops that use multiple minutes to connect to a postgres database that I connect to in seconds feels really stupid. (I'm old enough that I get what I need, they usually rather pay for a decent laptop rather than start a hiring process.)

2. My previous employer did something really smart:

They used to have a policy that you got a basic laptop and an inexpensive phone, but you could ask for more if you needed. Which of course meant some people got nothing and some people got custom keyboards and what not.

That was replaced with a $1000 budget on your first day an $800 every year that was meant to cover phones and everything you needed. You could alsp borrow from next year. So if someone felt they needed the newest iPhone or Samsung? Fine, save up one year(or borrow from next year) and you have it.

Others like me who don't care that much about phones could get a reasonably priced one + a gpod monitor for my upstairs office at home + some more gear.

And now the rules are the same for everyone so even I get (I feel I'm hopeless when it comes to arguing my case with IT, but now it was a simple: do you have money for it? yes/no)

I have a home in the southwest that is off grid and runs on solar plus lifepo3 batteries. It has been 5+ years now. My cost per kwh is below $0.008 as of today including all capital and maintenance. These numbers get a bit complicated, for example I run the AC much colder than I would if I was paying more for it. I have extra fridges and freezers I probably wouldn't if I had to pay higher per kwh. I "throw away" a lot of power too that I am not counting when the batteries fill up.

I have about 40kwh of storage. The batteries are in steel boxes and there are some basic precautions to take with them but lifepo3 has a very manageable risk profile quite different from lipo. Batteries and solar equipment continue to get cheaper, the same system I have is now 50% cheaper today then when I bought it, including tariffs.

The link really discusses more of a single neighborhood or medium industrial site possible type of technology. Really just a huge very hot pile of sand and steam turbine or propane cell generation. On a kwh basis it is probably not competitive with solar+battery unless your use case involved a lot of direct use of hot water or heating something.
