You're identifying the right problem (school and housing costs are completely out of hand) but then resorting to an ineffective solution (minimum wage) when what you actually need is to get those costs back down. The easy way to realize this is to notice that the median wage has increased by proportionally less than the federal minimum wage has. The people in the middle can't afford school or housing either. And what…

> (school and housing costs are completely out of hand) On the housing side, the root problem is obvious: Real estate cannot be both affordable and considered an investment. If it's affordable, that means the price is staying flat relative to inflation, which makes it a poor investment.

This is a misunderstanding of what makes something a good investment. Something is a good investment if it's better for you than your other alternatives.

Suppose you buy a house and then have a mortgage payment equivalent to the amount you'd have been paying in rent until the mortgage is paid off. At that point you have an asset worth e.g. $200,000 and you no longer have a mortgage payment. By contrast, if you'd been paying rent instead then you'd have to continue paying rent. That makes the house a good investment even if its value hasn't increased by a single cent since you bought it -- it could even have been a good investment if its value has gone down, because its true value is in not having to pay rent. Paying $300,000 over time for a house which is now worth $200,000 leaves you $200,000 ahead of the person who paid $300,000 in rent in order to end up with the asset you can find on the inside of an empty box.

Likewise, suppose you're in the landlord business. In one city it costs a million dollars to buy a two bedroom unit and then you can rent it out for $10,000/month. In another city the same two bedroom unit costs $10,000 to buy but then you could only rent it out for $100/month. If your business is to buy the property and rent it out, is one of these a better investment than the other? No, the ROI is exactly the same for both of them and either one could plausibly be a good investment even without any appreciation.

In both cases the value of the property doesn't have to increase to make it a good investment and in both cases the value of the property may not even come into play, because if you're planning to keep the asset in order to live in it or rent it out then you can't simultaneously sell it. And for homeowners, even if you were planning to sell it eventually, you'd then still need somewhere to live, so having all housing cost more isn't doing the average homeowner any good. If they sold they'd only have to pay the higher price to live somewhere else.

However, there is one major difference between homeowners and landlords. If you increase the supply of housing, rents go down. For homeowners that doesn't matter, because they're "renting" to themselves; they pay (opportunity cost) and receive (imputed rent) in equal amounts, so it doesn't matter to them if local rents change -- or it benefits them because it lowers local cost of living and then they pay lower prices for local things. Whereas landlords will fight you on that to their last breath, because that's their actual return on investment. Which is why they're the villains and they need to lose.

Man, it was just GPU for a while. But same boat. I regret not getting the 4090 for $1600 direct from Nvidia. "That's too much for a video card", and got the 4080 instead. I dread the day when I need to replace it.

The Radeon RX 9070 XT performs at a similar level to the RTX 5070, and is retailing around $600 right now.

Unfortunately, AMD drivers are beyond terrible and you'll experience frequent timeouts.

I think what the GP was referring to was the "new" owner of Sears, who reorganized the company into dozens of independent business units in the early 2010s (IT, HR, apparel, electronics, etc). Not departments, either; full-on internal businesses intended as a microcosm of the free market. Each of these units were then given access to an internal "market" and directed to compete with each other for funding. The idea w…

This happened at a place where I worked years ago, but not as 'on purpose.' We were a large company where most pieces depended on other pieces, and everything was fine - until a new CEO came in who started holding the numbers of each BU under a microscope. This led to each department trying to bill other departments as an enterprise customer, who then retaliated, which then led to internal departments threatening to…

Why is that a bad thing? If an internal department that’s not core to their business is less efficient than an external company - use the external company.

Anecdote: Even before Amazon officially killed Chime, everyone at least on the AWS side was moving to officially supported Slack.

How to determine which modules are actually needed, on a Debian system?

Set modules=dep in ( https://manpages.debian.org/jessie/initramfs-tools/initramfs... ) and run update-initramfs. I doubt that'll affect boot time but it reduces initrd.img size a lot.

Thank you. I'll spend some time to learn why that is not the default config setting.

Personally I use eBay and find the most barebones system I can, then populate the CPU+RAM with components salvaged from e-wasted servers. There are risks with this, as I've had to return more than one badly-bent workstation that was packed poorly. --- So the Dell Precision T7920 runs dual Intel Scalable (Skylake) and has oodles of DIMM slots (24!), but you'll need to use a PCIe adapter to run an NVMe drive. FlexBays…

>and a lot of blink codes when you encounter bad sticks Which sadly happens quite a lot with ECC DDR4 for whatever reason. >If you're feeling cheap and are okay with the previous generation, the Haswell/Broadwell-based T7910 is also serviceable The T5810 is a known machine, very tinkerable, just works with NVMe adapters (they show up as a normal NVMe boot option in UEFI) and even have TPM 2.0 (!!!) after a BIOS updat…

Forgot about Dell gimping Turbo Boost on that firmware.

Another route is the PowerEdge T440 (tower server), which does respect Broadwell-EP turbo logic without a reflash. Not quite as quiet as a workstation, though.

>For general computer usage, SSDs really were a once in a generation "holy shit, this upgrade makes a real difference" thing. I only ever noticed it on my windows partition. IIRC on my linux partition it was hardly noticeable because Linux is far better at caching disk contents than windows and also linux in general can boot surprisingly fast even on HDDs if you only install modules you actually need so that the auto…

How to determine which modules are actually needed, on a Debian system?

IDK; at the time i was using gentoo, in which it's natural not to have more modules than necessary because part of the installation process involves generating your own kernel configuration.

Even though it's not the normal way to install debian there ought to be some sort of way to build your own custom kernels and modules without interferance from the package manager (or you can just run it all manually and hope that you dont end up in a conflict with apt). Gentoo is the only distro where it's mandatory but im pretty sure this is supported on just about every distribution since it would be necessary for maintainers.

maybe not on an SSD but it definitely helps a lot on HDD by virtue of having far less disk traffic. The kernel's method for figuring out which modules to load is effectively to load every single module that might be compatible with a given device in series and then ask the module for its opinion before unloading it, and then once it has a list of all (self-reported) compatible modules for a given device it picks one and reloads it.

I was just pointing out the weirdness of AI bloat and complaint about application bloat....it's not irony...it's like, the zeitgeist.

lol. yes. I am behind the times complaining about app bloat. I should be complaining about LLM bloat. But I have enough bile in me to complain about both.

well, one of them just demands you get another 32GB stick of ram. The other wants you to pay for it's high voltage power lines, give it millions of gallons of water and provide zero benefits to the local community.

If bloat was given human form, it's definitely LLMs and their corporate financiers.

Every time I hear about gentoo I am torn between the "I should really be doing that" mindset and the "I don't have time for that" mindset.

Why does it not cache that list for next boot? On hardware changes one could add a boot flag to invalidate the cache.

That may not make sense for all installs, but for power user installs I think it would make sense.
