I’ve noticed when people are using generators to power a tool or appliance, they always directly plug into the generator. Then the generator is burning fuel reguardless of consumption.

How can that waste be reduced? A simple approach would be to plug your tool into a UPS (uninterruptible power supply) which is then plugged into the generator. This would help capture some of the excess energy when you are not pulling the trigger on a drill. Correct?

Possible flaw in this thinking: lead-acid batteries can only be trickle charged. So putting a battery in series only captures a small slice of the energy waste. Better than nothing, right?

I’m asking because I may need to install a generator for a whole house, and it’s not just for incidents. It will run daily in an off-grid house. So I’m trying to work out how to keep the fuel burn at a minimum and also how to fully exploit the available energy when fuel is being burnt (which should generally be during low sunlight times).

(edit) The UPS idea could backfire. IIRC, some UPSs are designed to always draw power from the battery while charging it at the same time. This is a superior design because it ensures that your appliance gets clean power that closely resembles a sine wave. UPSs that directly power the appliance from the mains and only tap the battery when mains go down have the disadvantage of sending potentially quite dirty wall power with surges and brownouts to the appliance. I think the always-use-battery design becomes self-defeating if using the UPS just to avoid generator waste. Correct? Though I’m confused because I don’t quite grasp how a lead-acid battery can charge as fast as it dissapates energy.. I would think the charging would be slower than the consumption and power to eventually be lost.

Sometimes a gmail user sends me an email. I object to that. In principle, I need be able to tell Google that I do not consent to them processing my personal data whatsoever.

If one of their users addresses an email to one of my email addresses, I do not want Google to store the message or even transmit it. They must refuse to handle my personal data, and thus refuse to process email traffic involving my email address.

I believe this falls under GDPR Art.18 or 21. But the question is, how can I submit my GDPR request to Google? I can write them a letter but I do not want Google to get my address. I don’t even want Google to know my name. The only thing I want Google to know is my email address, so that Google’s mail servers can refuse mail to that address. But the mere act of submitting a GDPR request inherently requires data subjects to prove their identity to data controllers.

A lot of tech knowledge is jailed in #StackOverflow, #StackExchange. Too much. The tech world is very dependant on this single gate keeper. This week, freedom to access SE’s indispensible tech knowledge has been lost.

A box of really old TomToms (softball sized) appeared at a street market a year ago, two for a dollar. I doubt anyone was interested in any and I doubt the seller would bother to return with them. They were probably be wasted.

In principle, old TomToms could be used to feed a smartphone. If you use a smartphone for navigation, these components compete to suck the battery dry:

• the color LCD
• GPS radio receiver
• WiFi¹
• GSM¹

(1) only applies to Google boot-lickers who enable location tracking in order to avoid the wait to acquire satellites.

The GPS is a significant drain because it’s heavy on non-stop calculations, which generates heat (wasted energy), and the heat itself hits the battery even harder.

We can do better. TomToms with bluetooth tend to suppot NMEA (I think). So the old TomTom w/outdated maps could be used purely to get a fix using its own battery supply, which it then transmits over bluetooth. So you toss TT in your backpack. Disable the GPS on your smartphone and enable bluetooth. Bluetooth is like 1 tenth the energy consumption of GPS. Then you enable mock GPS in advanced settings and run a FOSS bluetooth app that serves as middleware to feed the mock location.

The problem: OSMand and Organic Maps are both incapable of using mock GPS locations. And even if they add the capability, it would only be in their recent version which has already left behind older phones. (edit: well Organic Maps is not that bad… their latest version supports AOS 5)

Refusing to support Google means using airplane mode with location svcs off and being wholly dependent on GPS. And for whatever reason it takes me around 20—30 min to get a fix despite being in a large major city; every time. This must make Google happy. The old TomToms were faster at getting a fix. IIRC, they would take 20—30″ only the first time but quickly got a fix after subsequent power cycles in the same area thereafter.

Smartphones have the sensors to do inertial nav if you calibrate a starting point. But the apps don’t have their shit together yet. I vaguely a recall a FOSS app doing inertial nav, but not too useful if it results in a mock location that OSMand cannot handle.

As I was passing through Amsterdam, OSM lied to me several times. I don’t have the tools and means to correct the maps for various complex reasons starting with not having a good Internet connection, but really an Amsterdam local should get involved anyway because I’m not sure of all these problems.

Misinfo:

• Brouwerij Troost (52.36616°N, 4.87318°E) ← shutdown
• Manamana (52.35410°N, 4.89033°E) ← apparently shutdown; someone should verify
• Hecke Electronica (52.35243°N, 4.88725°E) ← shutdown; owner retired. It should be updated to say “/Formerly/ Hecke Electronica” until something replaces it
• Flower Burger (52.37226°N, 4.88566°E) ← replaced with a /cashless/ croissant shop.
• CT Coffee & Coconuts (52.35267°N, 4.89150°E) ← replaced with another similar shop. Not sure if other Coffee & Coconuts locations closed or just this one.

Missing info:

• Bierfabriek Amsterdam (52.37007°N, 4.89375°E) ← cashless¹!
• Brouwerij De Engel (52.37007°N, 4.89375°E) ← building is rightfully unnamed since the brewery was only there a couple years before bankruptcy. It should be updated to say “/Formerly/ Brouwerij De Engel” so people actually know the brewery is no longer there, until something else is established there.

¹ When a cashless merchant sells alcohol, it’s a trap and an injustice. Having records of alcohol consumption stupid and reckless because it denies consumers their GDPR Art.5 right to data minimisation. And it has consquences. E.g. a scandinavian home buyer was denied a loan because the bank discovered he bought alcohol regularly. Anyway, there will always be dumb consumers who pay for alcohol electronically, but in the very least OSM should mark cashless bars as cashless so wise consumers can easily avoid them. I walked out of my way to visit Bierfabriek only to discover they were cashless. Unlike other cashless bars, they were at least diligent about posting it.

IBM Thinkpads have a cult following in part due to not just a good design out of the gate, but the fact that the original designer refused to bend to pressure to change the design every year. The parts are interchangable to large extent between models spanning what, 3—5 years? The guy was under constant pressure; was told to give consumers something fresh by changing up the design. Luckily wisdom prevailed and he disregarded such reckless advice by responding with the mantra: ”if it ain’t broke, don’t fix it!”

I’m happy to buy Thinkpads over 15 years old, often sold for ~$10 on the street, because if something is broken or breaks it can still be used for parts to fix other models of Thinkpads from roughly the same decade.

Lenovo acquired Thinkpad from IBM and gradually fucked it up around the T410 or T450 models as they gave in to the demand of consumers giving a shit about shaving off every gram of weight possible at the expense of ditching rugged rollcages and ditching features like optical drives. Watch some videos of people trying to simply remove a keyboard from a T450 to see what I mean.

Whirlpool also has a reputation for not radically changing the design of internal components. I called a repair shop over a washer or tumble dryer that was like 15 or 20 years old. They said at that age, if it’s not Whirlpool they won’t even show up because when the parts change every year then spare parts quickly become unavailable (of course before people start needing the spare parts). They said Whirlpool is an exception because the same parts will be used for a decade or more, which then justifies the business of making spare parts for a prolonged time (I imagine as well the aftermarket likely thrives too).

Grain of salt though because I heard Whirlpool doesn’t always put their label on their own products and Whirlpools also end up getting labeled as Sears Kenmore. If Whirlpool rebadges something else as Whirlpool, how could the design have consistency w/other Whirlpool machines? Anyway, it was just an example and possibly flawed based on one repair shop’s opinion.

The problem -- no metrics

This is all just tribal knowledge propagated ad hoc by word of mouth. The masses don’t generally know this shit and probably most of them don’t care. I think Whirlpool and Thinkpad were not even diligent enough to advertise it. Maybe they did not even know in advance they would have design consistency over the years. Perhaps if they advertise: ”uses the same motor as previous 6 models”, they would fear that it would chase away foolish consumers who would regard that as ”old”, unevolved, or non-innovative. Those same stupid consumers who are brainwashed to chase “latest and greatest” are why we face so much unrepairable garbage on the market.

Since no one tracks design stability/consistency over time (not even Consumer Reports or similar orgs), there is no incentive for manufacturers to try to satisfy the unknown & unmeasured demand that no one is looking at.

If an existing point of interest is on the map and you add a favourite with the POI highlighted, the address field is automatically correctly populated with the street address. But when the favourite is later edited for any trivial reason (e.g. to change the name or description), the address information is lost. The field is cleared.
