When I was writing that, I was thinking of other platforms. For example: I had a GP2X at one point, which was a handheld console that ran Linux. It clearly wasn't a mass-market device, but it was an open platform with plenty of development tools. It should have been the sort of thing that appealed to homebrew developers. It was appealing for some, but it was up against the Nintendo DS with flash cartridges. There were almost certainly more flash cartridges than GP2X's in the world, even though they were a grey market item (at best). They didn't have a chance, and I think they only managed to produce one successor before going out of business. (Of course, there were other factors. This was right around the time of smartphones becoming popular. Smartphones may have crumby controls for gaming, but at least anyone could develop software for Android and the barrier to entry was relatively low for iOS.)

The Steam Deck, well, that has other things going for it. Yes, it is an open platform. Yet it, along with similar devices, are also PC compatible. That makes it appealing to developers, may they be developing games for Linux or Windows. Perhaps the biggest thing going for it is being backed by Valve, which is large enough to coexist with Nintendo and is unusual for a larger company in that they value an open ecosystem. To understand how unusual that is for a large player entering the market, just look at the original Xbox.

(fwiw I see the appeal of being pessimistic, and not even calling it, pace Orwell, optimism :)

Just trying to figure out the positive psychology of sharing*, how to reconcile that with the general idea of markets .. don't mind me.

(& maybe put a positive spin on autism?)

*there is something narcotic/creepy about the "abundance" mindset, which I haven't got a toehold on yet. It's like a Schelling point for people across the (political) spectrum who can't help but preemptively rationalize what their opponents would reflexively label fascism (or authoritarianism when they want to include China in the argument)

Sorry to be vague, there's not a lot of legible data out there

I'm much more sympathetic towards the strategy of definancialization/detertiarization-- with which Stiglitz has inadvertently steelman'd tariffs

(The idea that UK has been totally f**ked by tertiarization is mainstream, & the weather in California/Florida/Texas is not necessarily helping either :) to your point, maybe, Japan & Germany** have equally unhealthy attitudes towards intellectual entrenchment, that's why their bonds are so attractive :))

I didn't say anything along those lines. In fact, I want to highlight something in particular that I said that makes me wonder how much you wanted to react vs how much you actually read:

"Any ideas of stability in US society that may have come from their parents simply do not exist anymore."

I alluded to the 25 years of constant background combat deployments that most people aren't even aware of happening unless they are extremely impacted by it.

Some more so than others, like the old Onion joke: https://theonion.com/soldier-excited-to-take-over-father-s-o...

Interesting historically but if you want a real machine you can ride that's fast and comfortable there are commercial velomobiles available now that have been refined over several generations.

Ride as fast as a pro, shade in the summer, shorts and t-shirts in the winter, enough room to go camping or just bring a pie to a party, ass never hurts, and all for the same price as a top of the line road bike...

Mostly just exams this month haha, but technically a self-hostable workout tracking app.

The only self-hosted option I found was wger.de and while it looks great, it's a bit too much for my needs. I want something lightweight (so as not to hog resources on my cheap VPS) that does what it needs to do and nothing more.

It's been a while since I've done web dev, so I'm going to try out Deno (TypeScript) with htmx.

This is the limited offline version of the Internet for the rural communities but what we need is the local-first version of the Internet for the rural community [1].

Fun facts, about one third or 2.6 Billions of the world's population has no or very limited Internet connectivity [2]. The main root cause is most probably power not the infrastructure.

Most of the people in authority probably don't realize that this rural connectivity does not need a fast high speed network as long as it has connectivity. It can be slow as kbps bandwidth, a kind of "sipping" Bittorent based download, but a download nonetheless.

The main problem of the Internet connectivity it's not really the infrastructure itself but the overall power budget requirements for the connectivity infrastructure.

We need to bring back the very efficient wireles modulation for the remote and rural Internet as exemplify by the DMR with its very efficient 4-FSK [3],[4]. This type of wireless modulation employed constant envelope modulation that is far more efficient (8 to 15 times more efficient) than the alternative TETRA with comparable bandwith [5]. It's reported that DMR operates on 1 kWh per day while TETRA is on 15 kWh per day thus the former can be sustained by only solar panels but not the latter.

Please note that TETRA itself is not a very efficient modulation with π⁄4 differential quadrature phase-shift keying (π⁄4-DPSK) since it requires linear amplifiers due to its non-constant envelope wireles modulation. It's even worst for typical OFDM based system (e.g Wi-Fi HaLoW, LTE, 5G, etc) [6]. This is because a similar power budget setup to DMR would have required probably around 100 times more power or more than 100 kWh per day including the air-conditioning systems for the linear power amplifier systems [7].

Thus these remote and rural base stations can be potentially powered by merely solar panels and the infrastructure does not need to be expensive since the base station structure can be made from bamboo [8].

> Now, say the UPS driver and I didn't have that conversation. How do I get my money back? How do I prove the box had a brick and a bucket of tile mud? This isn't rhetorical. Keep in mind, the seller shipped me a PS4. The theft occurred at the carrier.

This is kind of the point. You bought a PS4 from someone on eBay who actually sent you their PS4. and then the carrier stole it. If you issue a chargeback, it's not the thief who loses the money, it's the seller who did nothing wrong.

You do want the police to investigate this so they can arrest the thief, because otherwise what is ever going to stop them from just stealing everybody's packages? This is literally their job.

But in terms of how to get your money back, the answer is that if you want the ability to do that you buy the insurance and then file an insurance claim. Then the cost ends up on the insurance company, which is set up to handle that, instead of random consumers or small businesses. And when UPS is providing the insurance itself, they then have the incentive to stop hiring thieves, which is where you want the incentive because they're the only ones who can really do anything about it.

A lot of Republicans are calling it a landslide, but I think they've forgotten what a landslide looks like; along with forgetting a lot of other things.

Out of 538 votes, in 2024, Trump had 312; in 2020, Biden had 306, just a few less, and Trump had 304 in 2016, only 8 less than his "landslide". In 2012, Obama had 332 and in 2008, he had 365. Clinton had 370 and 379. I wouldn't call any of those landslides though.

GHW Bush had 426 which is quite a lot, but Reagan before him had 489 and then 525. Those are landslides.

Nixon got 301 the first time, which is just a win; but he got 520 in his second term. That was a landslide.

I would draw a line in the sand at 90% of the electoral vote is a landslide, and anything less is puffery. Ranked by percentage of electors, Trump's "landslide" is only 44 out of 60. That's the saddest landslide ever. 58% of electors is a clear and undebatable win, but it's not a landslide and it's not a mandate, or even a large margin. It might be an indictment of the Democratic Party or some other lesser hyperbole though.

Tying this to APOE, specifically e4 which has an increased requirement for choline and when choline levels are low there can be a metabolic push that leads to elevated PHGDH activity and consequently, increased serine synthesis. That is a neat connection and maybe why when we study choline supplements we see positive results.

I'm making some minor changes to my personal site/blog to improve contrast, have a more uniform usage of colours throughout, and also replacing "categories" with tags so that I can have related content easily linked and searchable.

I may also finally finish implementing WebMentions support too as a kind of comment section.

I may also work some more on my long-term relaxation/creative maze generation and solver project.

At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.

It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.

To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.

Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".

The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.

So I guess what I'm saying is I've been casually looking around at jobs this month.

This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.

Get real. Companies with infinitely more money, staff, and robust security practices are hacked every day. The only difference is they put out a vague generic corpospeak statement whereas this one admitted it was caused by a skeleton crew on a shoestring budget getting caught out. Given the nature of their user base and how many others would love to see 4chan go down, if things were as bad as you imply then hackers would be taking the site down weekly.

The networks are insecure by standard. They are designed such that they can have "lawful intercept" by government entities. The key material on the SIM card is readily transferred between the carrier and SIM/eSIM card manufacturers, which enables multiple levels of supply chain attacks if the material is mishandled.

IMSI-catchers are not considered a security hole by the carriers or the standards bodies. SUCI/SUPI was put in at the request of phone vendors, if I remember correctly, and is still the only piece of public key cryptography in the networks. Everything else is symmetric keys.

No. No one is 'forced' to exceed the limit, not remotely, and there are plenty of drivers who, for a variety of reasons, drive at or under the speed limit (many large trucks, for example).

On a highway, driving slow in the left lane is not good, but doing 65 in a 70 in the right lane is perfectly fine.

Feeling this too. And AI is making it "worse".

Reviewing human code and writing thoughtful, justified, constructive feedback to help the author grow is one thing - too much of this activity gets draining, for sure, but at least I get the satisfaction of teaching/mentoring through it.

Reviewing AI-generated code, though, I'm increasingly unsure there's any real point to writing constructive feedback, and I can feel I'll burn out if I keep pushing myself to do it. AI also allows less experienced engineers to churn out code faster, so I have more and more code to review.

But right now I'm still "responsible" for "code quality" and "mentoring", even if we are going to have to figure out what those things even mean when everyone is a 10x vibecoder...

Hoping the stock market calms down and I can just decide I'm done with my tech career if/when this change becomes too painful for dinosaurs like me :)

Am I the only coder who has never really felt the desire to "be my own boss" and get rich from coding?

I was so against the idea, actually, that I avoided majoring in CS because I didn't want to ruin my favorite hobby by doing it professionally.

It wasn't until a few years after I graduated with my philosophy degree and couldn't find a career that I decided to try writing code for a living.

It's been great for me for almost 20 years now, and thankfully I still love to code for fun even though I do it all day professionally, but I have not felt the pull to try to form my own startup and try to get rich.

My favorite part of coding is having a problem and then figuring out how to solve it with the tools I have. I love working as a programmer because that is what I do all day, and someone pays me really good money to do it.

And I don't have to worry about all the other stuff like business models or funding or getting customers or talking to people, I just get a problem and do my favorite thing to solve it.

And I have more time to do other things because I am not hustling or trying to get rich.

> how that experiment ended

(not as taught from Texas-approved history books)

The Soviets lifted an unprecedented number of people out of poverty. This was unequalled until China in the following century. They would likely have achieved more and lasted longer without the constant harassment of capitalist countries. (Remember when the US even invaded Soviet soil? Most Americans do not.)

The US and some European powers managed to convince Soviets to switch to an American-style economy, run by oligarchs. Those countries proceeded to loot the Soviet Union for anything they could find. And so we have today.

This is an interesting observation:

> With AI, they could visualize the three-dimensional structure of the PHGDH protein. Within that structure, they discovered that the protein has a substructure that is very similar to a known DNA-binding domain in a class of known transcription factors. The similarity is solely in the structure and not in the protein sequence.>

Reminds me of: if you come across a dataset you have no idea of what it is representing, graph it.
Show HN: I'm building a better way to track ad performance across platforms
by onepaulmbw | 2025-04-28 00:19:01+00:00
, TL;DR - I'm building a tool that identifies which ad creatives I should keep or kill. Current tools are either too expensive or don't meet my specific needs.

For more context, read this post: https://www.reddit.com/r/PPC/comments/1k7md5u/whats_your_cur...

The tool is dead simple. Pull in ad creatives from Meta and Google, compare impressions and CTR's and get a verdict of which ads to keep or kill. That's it.

Though, this is the least interesting part.

The real magic? The ads marked as "keep" will be used to automatically generate similar ads. The tool learns which creative elements are most effective and regenerates variations based on winners. The ads marked as "kill" will save you on ad spend.

This is essentially my north star, and I don't believe other tools are doing this.

I'd love some initial feedback on this - why this might work, why this might not work, and what you'd like to see in a tool like this.

Metrics can be useful when they are thoughtfully chosen for the context in which they are used. The more abstract or synthetic a benchmark is, the less context there is to inform such a choice. Said another way, metrics characterizing synthetic benchmarks inherit/expose one of the key problems of synthetic benchmarks - a lack of context.

In practical settings, the way to characterize performance will be more clear from context, often giving one (-ish) clear metric for each dimension you care about. For example, if an endpoint has a hard timeout of 100 ms, then it's pretty interesting to look at the percentage of real world requests that are faster than 100 ms. If the same solution is also used in a setting where throughput is more important than latency, then an additional metric is probably needed for that use case. Multiple metrics are needed for multiple use cases to capture trade-offs being made between those use cases.

I am not entirely convinced that capitalism is the best system for producing software, especially established "infrastructure" software like OSes, web browsers, office suites, etc.

I'm open to the idea, and recognize there are problems with non-commercial software, too. But the critical difference between software and physical commodities is that replication of software, once written, has a marginal cost approaching zero.

I suspect that this difference significantly changes the calculus.

My personal feeling is we should really think outside the box here. I like some sort of hybrid system with government-funded software bureaus producing FOSS code to replicate successful and important "infrastructure" commercial products after five to ten years or so. People get cutting-edge software created by the market, and exploitative rent seeking on critical software is minimized.

That just means the penalties are not strict enough. Even worse, we're afraid to impose real penalties (jail) so we rather just "fine" people (because it's more humane?), which will affect those most likely to drive without a license more than the regular folk. The regular folk will be scared shitless and will just get a lift with someone till their license issue is resolved.

Your post proves my point quite exactly. Here you busy othering Jewish people by using language like "acting like you're the ones being persecuted". JEWISH PEOPLE ARE BEING PERSECUTED. I myself have been subject to anti-semitic treatment on/off throughout my entire life. I have been called the K word in the past. Current coworkers say things even though I am not even an Israeli citizen, and then are sure to add "of course Moshe we are not talking about you"...

I don't support what happened to Mahmoud Khalil. The Trump administration is evil. I might support Israel's right to exist, but I voted for Kamala because I support the US a hell of a lot more. None of the ordinary citizens of Israel or Palestine or the US is responsible for what's happening in Israel.

https://www.adl.org/resources/press-release/new-fbi-data-ref...

If you're not Jewish it might be a little difficult to understand. I know quite a few Jews who do not dare light a menorah in their window. Who don't dare fly an Israeli flag or identify themselves as Jews in any way. I am secular, but synagogues have to have armed security.

Jewish people != Israeli government.

By the way, Americans are absolutely safe traveling to Israel. You simple cannot say the same thing for almost any Arab country. Well, that's how Jews feel almost everywhere in the world.

I recall hearing about Japan putting speed limiters in all cars and using GPS to determine the road and therefore speed limit to set the limiter dynamically in vehicles. (Perhaps some details are wrong or confabulated; regardless, it’s a neat idea.) I’m in favor of such a system in theory; I’d be concerned about privacy issues but there’s no reason for such a system to require driver identification anyway.
