postpawl··on The momentum of the solar energy transition
It’s already pretty easy to ground mount some panels with something like: https://integrarack.com/ir-45-ballasted-racking
postpawl··on Serverless VPN Self-hosted
It’s pretty easy to DIY this with docker-wireguard on any cloud provider for a lot less than $50/month. Here’s their example docker compose, only ~20 lines: https://github.com/linuxserver/docker-wireguard?tab=readme-o...
postpawl··on Official Raspberry Pi NVMe SSD Review
The official Pi 5 NVME hat doesn’t work with the active cooler and doesn’t fit full sized SSDs. I think the Pimoroni NVMe Base is a better choice since it doesn’t have those issues.
postpawl··on Germany's 49-euro ticket resulted in significant shift from road to rail
Keep in mind there’s only about 50 miles of high-speed rail in the U.S. so far. With major cities like Dallas and Houston or San Francisco and LA still unconnected by fast rail, there's significant room to boost GDP and improve lives. Expanding rail isn't just about GDP growth, it's about enhancing daily living and connecting communities more effectively. As RFK famously noted, GDP measures everything ‘except that which makes life worthwhile’. Rail development does both, supporting the economy and enriching our lives.
postpawl··on Germany's 49-euro ticket resulted in significant shift from road to rail
Trains scale better than cars in dense areas and offer more than just emissions reductions. Good rail infrastructure is a big part of makes a large city world-class and improves everyday lives. Subsidizing trains is better than a lot of other uses of government funds.
postpawl··on Germany's 49-euro ticket resulted in significant shift from road to rail
Focusing on the cost-per-tonne for carbon reduction misses the broader value of railways. They're not just about reducing emission! They facilitate daily commutes, expand job opportunities, and help drive the economy. It’s a subsidy for businesses too.
postpawl··on John Rawls, liberalism and what it means to live a good life
This aligns with John Rawls’ idea that economic AND political systems should be structured to benefit the least advantaged. Rawls acknowledged government and markets are connected, and advocated for a fair system that ensures equity and supports all, not just the powerful.

The issue isn't simply that profit motivates bad behavior, but rather how our capitalist system, particularly through lobbying and legislation, disproportionately amplifies the influence of well-capitalized interests. For instance, the prevalence of high fructose corn syrup in our food supply isn’t just a random government subsidy; it's a direct result of agricultural subsidies shaped by powerful lobbies. These policies don’t emerge in a vacuum but are crafted in ways that systematically benefit the incumbents with the most capital, often at the expense of public health and smaller competitors. This underscores a structural imbalance where laws and subsidies are swayed more by capital than by the collective welfare of the populace.
postpawl··on John Rawls, liberalism and what it means to live a good life
While it's true that no system is perfect, recognizing the US's achievements doesn't mean we should overlook its flaws, especially when they're as tangible as rapidly rising costs for essentials like housing and healthcare. The harsh conditions of the past shouldn't justify complacency today. Instead (as Rawls recommends), we should acknowledge these challenges should compel us to strive for a fairer distribution of resources and opportunities, ensuring progress continues for future generations.
postpawl··on John Rawls, liberalism and what it means to live a good life
The trust placed in the US’s constitutional and legal frameworks to safeguard transactions is commendable but often doesn't reflect the full picture. While these systems are designed to prevent overt harm, they frequently fail to protect against subtler forms of exploitation prevalent in many capitalist enterprises. For instance, industries like fast food and tobacco not only legally sell products known to harm health, but they also heavily market these to vulnerable populations, maximizing profit at the expense of public well-being.

This issue isn't just about individual interactions or the inherent honesty of our society; it's about systemic structures that prioritize profit over people. The reality is that our economic model often allows, and sometimes encourages, practices that are detrimental to consumer interests but beneficial to corporate bottom lines.

postpawl··on Why are so many car YouTubers quitting?
Seems like a lot of the people quitting were just workers and producers that never had any real ownership stake in the business. After Covid they were already working like individual creators, so going and doing their own thing doesn’t seem like that big of a change.
postpawl··on [dead]
I’m assuming this is a joke, but there’s no explanation on the page about what ELIZA is and it’s not capitalized in the title of the post.

postpawl··on Ask HN: How do you organize and store your cables?
I recently used a Treedix USB cable tester to figure out which cables were worth keeping. It’s probably not worth keeping any charging-only USB cables since you’ve got so many data cables.
postpawl··on Raspberry Pi CM5 seen in the wild
> there's enough SoMs with good platform support at this point

You’re talking about the new (and expensive) Turing RK1 and the Nvidia Jetson as alternatives?

postpawl··on PiVPN v4.6.0: The End
Docker-wireguard: https://github.com/linuxserver/docker-wireguard?tab=readme-o...

You set the number of peers and it generates that number of folders with certificates and QR codes for you.

postpawl··on PiVPN v4.6.0: The End
It’s probably better to just use the wireguard docker container setup instructions now: https://github.com/linuxserver/docker-wireguard?tab=readme-o...
postpawl··on Deaths at a California skydiving center, but the jumps go on
The underfunded IRS during that time disproportionately audited people who got the Earned Income Tax Credit because it was easy and cheap compared to going after rich people. Where are you even getting that “publicly stated they weren't doing audits of anyone below 400k” from? Why does it even matter what they publicly stated at this point?
postpawl··on Ask HN: In Dallas for the Eclipse?
I’d recommend going to at least one restaurant in the different neighborhoods like Greenville, Knox/henderson, bishop arts, uptown, and deep ellum. Use google maps to search for the name of the neighborhood and just pick a place with a bunch of good reviews. Dallas is pretty spread out and downtown isn’t really where most of the good places to eat and drink are.
postpawl··on The wealth of the 1% just hit a record $44T
The critique of the 1% is more of a call for a system that is doing less exploiting of labor of the many for the benefit of a few, which has been leading to these huge social, economic, and political disparities.
postpawl··on Intel to Receive $8.5B in Grants to Build Chip Plants
> nice job, if you can get it

TSMC is paying around $23/hour to manufacturing technicians in Arizona. They’re also sending people to Taiwan to get trained and apparently it’s brutal enough that most people drop out of the program.

Asianometry did a video on this recently: https://youtu.be/Nk-lBok9_TU

postpawl··on Apple 'like The Godfather' with new App Store rules
You’re talking about “strict tracking protection” that’s basically like browsing the web in incognito mode? That’s not really like Adblock origin. You know they only allow their own browser engine (WebKit) on iOS?
postpawl··on Apple 'like The Godfather' with new App Store rules
It’s barely about security. It’s tough to do things like getting Firefox with an ad blocker on an iPhone.
postpawl··on How to Produce Green Hydrogen for $1/kg (2023)
“One kg of hydrogen contains about the same energy as a gallon of gasoline. Today a fuel-cell electric vehicle with 1 kg of hydrogen can drive approximately 60 miles, compared to conventional vehicles, which get about 25 miles on a gallon of gasoline.”

postpawl··on PG&E claims no connection between rate increases and $2.2B jump in earnings
BigCos using government to erect barriers to entry isn't a distortion of free markets. It’s an inherent outcome of capitalism's maturity, where monopolies and oligopolies emerge naturally.
postpawl··on The lithium-ion battery may not be the best bet for EVs
When most people refer to lithium-ion batteries, they're often thinking of chemistries other than LiFePO4, like NMC (Nickel Manganese Cobalt) or NCA (Nickel Cobalt Aluminum), which have higher energy density.
postpawl··on Canadian government banning Flipper Zero to combat auto theft
Although people have a role in forming societal structures, it's not a simple matter of choice when entrenched interests shape the rules. The perception that individuals consent to inequality by focusing on their own lives misses the broader context of systemic barriers. Expecting people to prioritize civic action over making a decent living underestimates the challenges they face. The system needs to facilitate equal participation through reforms in political finance, such as addressing the implications of Citizens United, or revisiting institutional frameworks that may dilute the majority's voice (the Senate). It's about creating conditions where engagement is a realistic option for all, not just those who can afford the time and expense.
postpawl··on Canadian government banning Flipper Zero to combat auto theft
The challenge isn't that people don't want to engage; it's that the demands of daily life, such as working long hours to make ends meet, leave little room for the kind of sustained political involvement that wealthier individuals can afford. When we say that people delegate their power to figureheads, it might be more a reflection of an unequal system that doesn't effectively support widespread civic participation, rather than a choice made out of apathy.
postpawl··on Canadian government banning Flipper Zero to combat auto theft
In reality, those with significant wealth and power end up shaping policy. This can lead to public disengagement, as many feel the system is not truly representing their interests.
postpawl··on Framework Laptop 16 Review
No modular GPU makes Tuxedo Pulse 14 a pretty different product?
postpawl··on We migrated our PostgreSQL database with 11 seconds downtime
There are a lot of gotchas with using DMS (which seems to use pglogical under the hood). Since it’s not hardware-level replication, you can run into issues with large rows/columns/tables and it doesn’t really handle foreign keys. It may not handle some special data types at all. You also need to update the sequences after the migration or you’ll get errors about duplicate primary keys. You can also have issues if you don’t have proper primary keys, because it doesn’t always copy the entire row at once.

If the databases are within the same AWS account, it’s likely easier to use hardware-level replication with global database or snapshots to do migrations if you’re ok with 4-5 mins of downtime.
