Maakuth··on Solar panels disguised as terracotta tiles in Pompeii
The are that's going to covered by the next tile when stacked is well known in advance. Obviously solar cells are not installed in this area. As for the shading from leaves or something, typically diodes are installed in solar panels to prevent current flow into the shaded parts. This helps mitigate the power loss from shades.
Maakuth··on BP sees biggest profit in 114 year history
> I'm surprised by how short termed is the strategy to actually keep up with 'market' prices.

It's supply and demand in action. Each oil company has limited capacity of production and not much flexibility to increase it in short term. As part of the supply is no longer available, there is less oil available in the market. The market mechanism drives the price up to a level where supply and demand are in balance. So the migration of oil consumers to alternatives is exactly what's supposed to happen in this case.

Moreover, a single company does not have a real choice to sell for cheap. First everyone would choose this vendor for their oil needs. But as their stock and production is limited, they would soon run out of oil to sell. Even a cartel or government decision to lower the price does not cut it, because it kills the demand side incentive to find alternatives. Then you'd be in a situation where oil is cheap, but not available.

Maakuth··on Why Finland Selected the F-35A (2021)
As I see it, the budget and schedule overruns are not functional faults in the airplane itself, but in the program that produces and maintains it. As such, it is not in the scope of a tender process for procuring such planes outside the US.
Maakuth··on Hyperscale in your Homelab: The Compute Blade arrives
That's impressively low, considering the amount of storage capacity and the performance potential for the time you need it. It goes a long way towards paying for itself if you replace some old Xeon server with it.
Maakuth··on Hyperscale in your Homelab: The Compute Blade arrives
It was this board: https://www.supermicro.com/en/products/motherboard/a2sdi-2c-...

I think it was idling at something like 30-40W with four HDDs and a UPS. I didn't have an especially efficient PSU and the UPS must have taken some power too. The motherboard alone would draw as little as 15W, I suppose.

Maakuth··on Hyperscale in your Homelab: The Compute Blade arrives
There are Intel Atom CPUs that support ECC. I had a Supermicro motherboard with a quad core part like that and I used it as a NAS. It was not that fast, but the power consumption was very low.
Maakuth··on Bulldozer, AMD’s Crash Modernization: Front End and Execution Engine
8350 is Piledriver, the design evolved from Bulldozer. It addressed many of the Bulldozer shortcomings.
Maakuth··on EV batteries alone could satisfy short-term grid storage demand as early as 2030
The price level would be determined in the market of course, maybe most vehicle owners would be ready to participate with lower reimbursement ratio. Anyway, I doubt this would cause a lot of stress to the distribution grid as the vehicle batteries are probably closer to the loads than the large scale power stations. The EVs powering neighbourdhood ACs and so on. So at least the distribution transformers could easily see lower load than without V2G.
Maakuth··on EV batteries alone could satisfy short-term grid storage demand as early as 2030
What if you were reimbursed 5x your meter price for the power you sell back to the grid? With electricity spot market, this sort of money is around and should of course go to the vehicle owners, at least a big share of it. Only a fraction of the total battery capacity would be involved in this scheme and with light load, so the battery degradation would not be that big. And this would not happen daily.
Maakuth··on Revisiting KDE
I use KDE on Fedora in my daily driver. I have not experienced issues that would suggest of KDE being lower than first class. In Fedora it's installed with dnf groupinstall -y "KDE Plasma Workspaces"
Maakuth··on Motorola 68030 wire wrap prototype
G3 was PowerPC though, not 68k. ARM is actually the fourth Mac ISA, after 68k, PowerPC and x86!
Maakuth··on Nokia and Airbus elected as judges at the UPC, an unheard corruption of Justice
The network equipment business was largely a sideshow back when their phone business was successful. Apple and especially Android outcompeted the phones, so networks is what they have left.
Maakuth··on Tether USDT is depegging from dollar
So is there now an arbitrage opportunity? Or are the fees so high that it's not practical for 2% price delta?
Maakuth··on I finally found a use case for my Raspberry Pi Model B+
Easy OS installation and experimentation by swapping SD cards is a neat feature made possible by this design choice. You can improve durability by underprovisioning - SD card of 64 GB capacity costs a dozen euros or so. Judging by the popularity, RPi isn't generally seen as pointless but certainly it's not the best option for every application.
Maakuth··on OpenRCT2: Open-source implementation of RollerCoaster Tycoon 2 with new features
Those are commercially available from gog.com: https://www.gog.com/en/game/rollercoaster_tycoon_2

And the data files from the demo version do the trick too.

Maakuth··on Lost something? Search through 91.7M files from the 80s, 90s, and 2000s
Many if not most WiFi clients send a list of SSIDs they would want to connect in cleartext in their directed probe request frames in the active scanning mode. I expect there are attackers automatically advertising these networks to lure in devices.
Maakuth··on Meta Meets Microsoft
Moreover, surely many companies dropped $1k per employee for better equipping their workforce to work remotely during the pandemic. Yearly IT costs per seat surely exceed $1k in many if not most companies, so this is not really expensive.
Maakuth··on Europe’s Energy Crisis Forces Factories to Go Dark
(Not really) Surprising number of pro-Kremlin views expressed by accounts that were created in the last few months. Welcome to HN, Internet Research Agency (https://en.wikipedia.org/wiki/Internet_Research_Agency)!
Maakuth··on Xerox PARC – Office Alto Commercial (1979) [video]
The timeline here seems quite contracted. Windows PCs started to really sell after launch of 3.0 and the PCs with that did not even have CD-ROM drives by default, let alone DVD. I would say DVD drives started to be a norm at least a decade after the rise of commodity PCs, if you count from Windows 3.0 launch in 1990. And in the PCs that first shipped with DVD drives, the CPUs were not powerful enough to decode DVD video in real time so accelerator cards (and their crummy software) were needed, keeping the appeal limited.
Maakuth··on Homemade Heat Pump Manifesto (2009)
That's for single head, yes. From my point of view, single head is the norm here. In here too, I would imagine multi-head to be cheaper per head than single head.

Here in Finland you can get a split system good for -30 Celsius for 2-3k€ including installation. Mitsubishi is considered the best, but others are available. My Panasonic has been working fine.

Pray tell, when did Georgia and Ukraine join NATO?
Maakuth··on German digital signage ban prompts confusion
This is not false, but the economics are not good for the full round trip. There are efficiency losses in the conversion both ways and hydrogen storage is not fun as it is very low density and due to small molecule size, prone to leaking through almost anything. Probably a lot of hydrogen will be produced this way during renewable peaks, but mainly it would be for industrial processes that need it.
Maakuth··on Bank of England warns the UK will fall into recession this year
Supply and demand at work. If there is less demand of fuel, it's price goes down, if everything else stays the same. Certainly everything else does not stay the same, but at least partially the price increase pressure is alleviated.
Maakuth··on Volkswagen enters battery business with $20B investment
1:5 in what? I mean if it takes five times the cobalt to manufacture a kilogram of battery compared to a kilogram of gasoline, that sounds like a point in favour of EVs. You can only use that gasoline once after all, whereas the lithium could serve the full vehicle lifetime.
Maakuth··on I fucking hate Jira
Single letter hotkeys are pretty bad. If it's not an input field you've focused but the page itself, you might assign the ticket to yourself and set it to some crazy state before you realize the focus is all wrong. Ask me how I know...
Maakuth··on Credit Scores Can Run – and Ruin – Our Lives
Isn't that what class action suits are for?
Maakuth··on The Xinjiang Police Files
This is the sort of background I asked for. Admittedly I've not followed the topic closely, but this is the first time I hear about this sort of connection with Uyghyr activism.

At least in this case the reporting seems to be based on verified information and journalists working independently of Dr. Zenz.

Maakuth··on The Xinjiang Police Files
I suppose it would be helpful if you provided some grounds on why you do not trust this foundation. There are other messages in this discussion showing distrust in the foundation and Dr. Zenz, but none provide background for that.
Maakuth··on Finland will seek NATO membership immediately
The process has been going on in unofficial sense since the start of Putler's war, but to minimize risks, the official process is only kicked off now. It was only started after it was verified that there are no internal or external blockers and that Sweden is in lockstep.
