patrickk··on Why Northern Ireland has no flag
Interestingly, the UK and ROI are not in Schengen[1], but jointly have a Common Travel Area[2], which means Irish passport holders can live and work in the EU and in the UK, post Brexit. British and Irish citizens can generally live and work in the other country without visas.

patrickk··on Electric Scooter Revival (2019)
Nice project! The unknown wires everywhere brought back memories. I did a similar project, hacking an escooter to add Bluetooth functionality in order to control it via a smartphone app:

It allows you to increase the top speed among other functions.

patrickk··on Samsung Electronics cultural issues causing disasters in foundry, LSI, DRAM
Your experience closely matches what I’ve seen in another Korean company, in a different industry. Tedious manual reports (for cover your ass reasons), PowerPoint used for everything, crap internal tools because of a strong ‘not invented here’ culture, mid 40s to 50s guys of mediocre talent but often inflated egos, and so on. Thanks for typing it up.

patrickk··on Ask HN: When did tech stop being cool?
Games nowadays are often updated for a long time (e.g. Factorio), so the initial launch date is less relevant. I would argue that indie games are doing really well right now, and the AAA gaming companies' reputations are in the gutter.

EA, DICE, Take Two, Ubisoft, Bioware, Konami, even the once vaunted CDProjekt Red's reputations are in tatters (of course, they still sell tons of games). Gamers are tired of copy and paste money grabs, full of bugs on launch and overhyped to the moon.

The accessibility of game development tools to almost anyone globally, the pandemic, and the relative ease of digital distribution is a boon to indie game makers (Steam, Epic, Itch, GOG, Indiegala....).

Valheim, Among Us, Project Zomboid (launched 2013, becoming much more popular recently), Escape from Tarkov are all examples of indie games doing well. Check out /r/patientgamers and related subs and you'll see more examples.

patrickk··on Sounding the alarm: How noise hurts the heart (2021)
Germany too. You can find noise maps[1] with measurements for all kinds of noise, including car noise, aircraft noise, industrial noise, etc. This allows you to make a more informed decision when renting or buying a new home.

In the area around Frankfurt airport (FRA) there is ongoing noise monitoring[2] to make sure that the noise doesn't constantly exceed the agreed limits. The aircraft can only fly between 6am-11pm daily, in one of Europe's busiest airports. The local residents won a court case against the airport, so they are entitled to free triple-glazed windows, and a device installed into the wall to extract CO2-heavy air from the house interior (important for sealed off bedrooms).

There are restrictions on noisy activities you can do at certain hours[3], such as hoovering your place, blasting your Hi-Fi or car stereo. Initially, I thought it was overly restrictive, but it's the best way of ensuring people can live densely and not go insane from inconsiderate neighbours.

Finally, apartments are generally thick concrete walls with high-quality windows and doors, both interior and exterior. Interior doors are usually solid material, with a rubber-lined bezel creating an acoustic and thermal seal between the door and the frame. I wasn't used to that before moving to Germany, it's quite impressive and definitely improves your living quality in an apartment.

patrickk··on Germany boosts renewables with “biggest energy policy reform in decades”
This excludes connecting further to Germany’s neighbours, e.g. using Norway’s hydro exports as a battery.

https://en.m.wikipedia.org/wiki/European_super_grid

Ireland and Britain has massive offshore wind potential that is only being slowly ramped up, for example. Macron has announced a new nuclear reactor building program, so potentially more carbon-free electricity to nuclear-adverse Germany. The massive Danish offshore wind park/energy island has yet to come online but will supply northern Germany.

And if you want to go even more exotic, you could get 24/7/365 renewable energy by piping geothermal to continental Europe from Iceland which has an oversupply. Or even building enormous solar parks in the Sahara (geopolitical risks notwithstanding).

There are plenty of options enabled by geographic distribution of supply without even looking at storage. The main problem is the lack of political will until now, which is changing with the realisation in Germany that Russia isn’t a reliable partner.

Edit: none of these rely on any technical breakthroughs either, merely ramping up the interconnection of grids and renewable sources of electricity.

patrickk··on Why I will never buy another Samsung device
Prior discussion, hope it helps:

TL:DR- LG CX tv, never connected to the internet, "smart" functions come from a separate device. It's also behind a pihole for what it's worth.

patrickk··on Thank You, Valve
> I feel like I am in a "late-game" stage of gaming. I have sort of an overview of what is going on, but a major percentage of games simply look not interesting (anymore) to me.

I feel similar. I usually play slightly older AAA games with the bugs ironed out, indie or AA, or games 5-20 years old based on the amount of interesting looking mods available. Reliving games from your childhood with quality of life improvements, new game modes, campaigns and better graphics is a blast. Browsing the most modded games on ModsDB or NexusMods is great for inspiration. /r/patientgamers is good too.

So many AAA developers and publishers are pushing out nonstop cash grabs with no respect for players, especially with sequels in previously beloved franchises. EA, Rockstar, Ubisoft etc are all at it. It was inevitable when gaming became so mainstream and more profitable than Hollywood.

patrickk··on Adblocking people and non-adblocking people experience a different web
> You can't even buy appliances designed perform their function well

You can't research good appliances either online, because the SERPs are stuffed with SEO-ed blogs and sometimes industry magazines, monetized with Amazon affiliates or other networks, with titles like "5 best dishwashers in 2022". Unless you know someone in the industry or offline with knowledge you don't know what to buy.

This is noticeable in many other consumer goods verticals, e.g. good luck researching decent home gym equipment that is durable and not overpriced with fat margins.

There's no adblocker for this problem either. Google is complacent with their fat ad revenue and monopoly on search and doesn't care.

patrickk··on Nvidia prepares to abandon $40B Arm bid
Chinese price dumping from state-sponsored companies also largely wiped out the German solar PV industry[1,2]. Germany was an early innovator in solar, especially in regards to inventing the concept of a feed in tariff when solar PV was still hideously expensive, thereby driving wider adoption. Planet Money did a nice podcast on the history of it [3].

patrickk··on I automated my job over a year ago and haven't told anyone
It’s difficult to disrupt companies or even whole industries that are stuffed with busy work, and had management completely uninterested in efficiency. Especially prevalent in some (non US, non Tech, high barriers to entry) work cultures that value jobs for the boys and value relationships over merit or efficiency.

I’ve seen countless processes that were locked in place to protect the status of prima Donnas in Legal or Finance, which must rubber stamp projects or infrastructure requests. So nothing gets done except what suits those inside the broken process.

patrickk··on I automated my job over a year ago and haven't told anyone
AutoHotKey and Pulover's Macro Creator[1] (which spits out AHK scrips from mouse and keyboard input) can do a similar job in a windows environment, and can trivially click on UI elements on the screen via PixelSearch. It runs lightning fast too, and is simple to learn.

I've used it to automate simple web games for shits and giggles.

This description falls under the "duct tapers" category of Bullshit Jobs[1], according to David Graeber:

> duct tapers, who temporarily fix problems that could be fixed permanently, e.g., programmers repairing bloated code, airline desk staff who calm passengers whose bags do not arrive;

In this case, perhaps its easier and cheaper to simply pay this guy 90k per year to run this script rather than get an entire law firm, likely staffed by extreme tech Luddites, to switch to using the cloud solution properly.

I've also seen worse waste in other industries.

patrickk··on Locked out of 'God Mode', runners are hacking their treadmills
Although it could be a general concern, it unlikely to affect me.

Since all the HDMI connections are via a (slightly older, non-connected) AV receiver, its almost impossible for this to affect my setup. But it's indeed a sleazy move by those setting the HDMI standards.

patrickk··on Direct conversion of CO2 to solid carbon by Gallium-based liquid metals
I'm not sure if it's more efficient than the methods you mentioned, but Project Vesta makes some pretty bold claims using the carbonate-silicate cycle. More details:

patrickk··on Locked out of 'God Mode', runners are hacking their treadmills
I got an LG CX tv and never hooked it up to the internet. It acts as a (very pretty) yet dumb tv like the old days.

An Nvidia shield handles all the streaming, kodi handles local files etc, all the media that I could possibly need.

4k is handled by default out of the box.

Surround sound is handled by an AV receiver. (Atmos surround is available if I wish to further upgrade the 7.1 speakers).

It can be done. Granted, it’s not cheap and installing all these devices can be painful, but still.

patrickk··on How to build homes with virtually no heating (2020)
Modern air or ground source heat pumps tend to be quiet, even silent, at least according to some deep dives down the Youtube rabbit hole on passive houses. Check out the "Moonstone house" on Youtube for example.

patrickk··on Summary of Atomic Habits
The E-Myth (Revisited?) is a book that suffers badly from having page after page of sentimental drivel, padding it out significantly.

The core message is quite insightful and worth knowing, but the author doesn’t respect the readers time.

Edit: some book notes from Derek Sivers-

https://sive.rs/book/EMythRevisited

It’s like a modern open world video game in book form.

patrickk··on Kodi: An Open Source Home Theater System
There are a plethora of streaming boxes out there. Arguably the best is an Nvidia shield pro, which I use. It runs everything you want and more (YouTube, plex, jellyfin, iptv, local tv station apps...), via the Google Play store. If you want to run unofficial apps, you can unlock that with some initial setup. After that it’s dead easy to use for non techies and blazing fast compared to cheaper android boxes or apps that are packaged with smart TVs.
patrickk··on Kodi: An Open Source Home Theater System
The scope gets bloated and the app unfocused. Most people wouldn’t read eBooks or comics from a big screen interface for example, but use a dedicated app for that. Keeping a cinema app primarily focused on video means it is leaner and meaner for the majority use case.

Excellent podcast with the author:

patrickk··on Judge tosses $4.5B deal shielding Purdue's Sackler family from opioid claims
> Don’t get me wrong: the Sacklers are disgusting people who contributed to the opioid crisis. Can a link be established that meets the relevant legal threshold for liability? Again, genuinely curious.

There's a ton of internal Purdue emails, showing that the management was aware of the problems from 1996/1997 with their drug and it's potential for addiction.

There's a superb synopsis of the case by an investigative journalist who wrote a book on this case, exploring the players involved as all the aspects to this case:

patrickk··on Why battery costs have plunged since 2010
Almost all e-bike batteries sold to consumers are ridiculously overpriced[1] relative to their components. Especially those from reputable brands like Bosch and Shimano which supplies most of the better e-bike brands on the street.

It’s a combination of having relatively well-off consumers, who lack the time/knowledge to start messing with their expensive machines and lack of generic spare parts due to the likes of Bosch locking down their components, and creating specialised computers (similar to how modern cars work) so that only authorised repair shops can work on them.

patrickk··on Buying an ebike
> The article does make a brief callout to 'anti-theft', and yeah, can confirm that this is important, but not sure what the best approach is.

From my experience, the absolute best thing is "out of sight, out of mind", so park your e-bike in a dedicated parking garage at work, or in a locked shed or inside your home, if at all possible. I live in an area with loads of bike thefts, and luckily this has saved me so far. I would almost go so far to say that I wouldn't use my e-bike unless I knew in advance that I could lock it up somewhere off the street.
