Incidentally, WeChat mini apps (and the equivalents in AliPay and other services) are essentially specialized websites.

WeChat itself on Android bundles a Chromium-based engine to run these mini apps.

Most people in China are using Chromium frequently, even if they don't think of it as a browser.


A big part of the problem in Manhattan is that most places don't have alleys. There is nowhere for the trash to be left except on the sidewalk.

Some cities have the trash trucks drive around playing music, ice cream truck style, and you are required to bring your trash out to the truck. Logistically that would probably work in Manhattan. Politically I don't think you would ever be able to get it done.


Most places in the US don’t have alleys. The problem isn’t the alleys, it’s the trash cans. Most modern US cities have cans that can be lifted by the truck, and then emptied. NYC, on the other hand, insists on just leaving everything in flimsy bags, open to the rats.


Most places don't have a mostly continuous street wall with little/no setback from the public street/sidewalk.

Part of the problem in Manhattan has been that many buildings really do not have any place they could store those sorts of bins, or at least not in the quantity of them that they need for their trash output.


I wonder if there's any free space underground? https://www.youtube.com/watch?v=OYxaKw_CfeY


Manhattan isn't unique — and as far as I've heard, they've recently copied systems in use in Madrid (bins in parking spaces) and London (wheelie bins) to solve the problem.


Which aircraft you are on is at best loosely correlated with the quality of in flight entertainment system you will use.

Seats are purchased by the airlines, they are made by separate manufacturers like Recaro or Zodiac and not by the airframe manufacturer (Airbus or Boeing). While the seats obviously need to be compatible with the airframe, there are a wide variety of options and it is common for airlines to refresh old airframes with new seats.

IFE systems are not manufactured by the airframe or the seat manufacturers, they are made by companies like Panasonic. They obviously need to be compatible with the seat, and my understanding is that it is uncommon for airlines to update the IFE system without also replacing seats.

So, while a newer aircraft type typically will have a more up to date IFE system, there are plenty of old aircraft that have new IFE and seats retrofitted.


The interior may be refurbished only 1-2 times during the economic life of the airframe, so the rule generally still holds. 747s are old enough that chances are, even the IFE tech installed during the refurb is outdated. A380s aren’t yet old enough to have had their interior refurbed for the first time, so their IFE tech is similarly outdated.


Yes they are. Qantas have refitted their A380 fleet at least twice now since entering service in 2008.

They need to do this to remain competitive in the premium cabin market.


Spamhaus or another IP reputation provider will contact your hosting provide or ISP and warn them that either: - You need to follow their best practices (which practically for me meant paying for a subscription) - Or your upstream net block would be marked as untrustworthy (which basically blocks email delivery from that IP range)

You can imagine what your hosting provider or ISP will do with this.

That's totally not a protection racket.


I have 7 Mitsubishi heat pump head units being controlled using ESPHome running on D1 mini clones (ESP8266). The D1 mini clones are powered by and interface with the head units with Mitsubishi's CN105, which is just 5 volt UART.

The total cost was maybe $30 of parts on AliExpress.

I use 433Mhz Acurite temperature sensors with a software defined radio (rtl433) running on my Home Assistant box to have remote temperature sensing. The 433MHz sensors are cheap, have good range, and have excellent battery life.


Are you doing temperature control by yourself or are you feeding them to the Mitsubishi units as a remote temperature reference?

I know the Mitsubishi "wired controllers" (basically the official thermostats) can provide remote temp to the unit and the unit has DIP switches to select between thermostat-reported temp and internal return air sensor temp.

I'm not sure if CN105 has a way to provide this temp ref - if so, you could try it. Just make sure to set your wired controller (if any) as a "secondary" controller (otherwise it will also send its temp every second and overwrite the one you sent) and then set the proper DIP switch.


T-Mobile has a SIM lock feature that you can enable to block at least most employees from being able to swap your SIM. You can enable it in the account management app or website.

I was able to verify that it worked because an employee in a store literally could not transfer my SIM with it enabled. Their iPad app just gave an error of "customer has SIM lock enabled".

Interestingly the T-Mobile employee had never even heard of this feature, which suggests that basically no one uses it.

T-Mobile already does exactly this for eSIM transfers, though the waiting period is 10 minutes, not 48 hours.


Energy usage isn't measured in "time the dryer needs to run".

A typical US vented dryer has a 5500 watt element, although it doesn't use that amount of power continuously since it cycles on and off.

I have no idea how much power a typical dryer uses in Switzerland, but the heat pump ventless dryers you can get in the USA now typically use around 1000W when they are running. They typically take around 90-120 minutes to dry a load depending on how big it is and how much water there is to evaporate.

This white paper has a nice graph that shows power usage over time: https://www.energystar.gov/ia/partners/pt_awards/SEDI_Fact_S...

You may notice that, while the heat pump dryers take longer to dry, they use so much less power that it more than offsets.


In EU a common classic dryer absorb 2000W, a heat-pump one around 800W. Of course they have a certain load limit, you can't dry an entire winter bed lingerie all together.

Anyway most washing machines (those who also dry and those who only wash) and dishwashers absorb around 2kW when they heat the water, for washing machines typically only one time (two if they also dry) for dishwashers 2 or 3 times. Running time depends of the program you choose: the quickest wash in general is 15' as the quickest dry, a typical wash for misc clothes is 1h/1h30', drying is 20' (much depend on how quick you can run the washer spin cycle, at 1500rpm 15' drying is enough in most cases). A dishwasher takes typical cycle is 1h30'.

Of course professional dishwashers run in few minutes, and they are far larger than the "standard 60x60x90 cm size", washing machines and dryer take the same times even at nearly-industrial product.


…while the heat pump dryers take longer to dry…

I’m not even sure how true that is with the latest all-in-one washer/dryer combos. The ones released in the U. S. just this year, one of which we have (GE) can do a full load wash and dry in about two hours, which is probably about how long our old separate units would take. Or at least close enough that we don’t notice or care. A load of blankets might be 2.5 hours.

And if takes a few minutes longer, the lack of a vent and the fact that it runs on a 120V plug more than makes up for it.


> I’m not even sure how true that is with the latest all-in-one washer/dryer combos.

Haven't used all-in-ones, but one possible concern: lack of pipelining (to use a CPU term).

I wash darks first, and when they finish washing I put them in the dryer. While darks are drying, I can put whites in the washer. When the darks are dry, I remove them, and then put in whites to dry. (Continue for any further cycles/types of clothing.)

With an all-in-one I have to wait for darks to completely finish before anything can be done with white (etc). Is this a problem for you?


Here in Colorado (Denver metro) I frequently get items same-day, though most items are still 1 or 2 days.


Modern deep packet identification gear looks at packet size and pacing to distinguish video traffic patterns. It is possible to fool these systems, but it is not trivial.


Any reason fast.com couldn’t stream a video as the test content?


Yes, this is exactly what it does, and it's a very clever trick by Netflix to discourage their traffic from being throttled!


I think it does pull a real video, I'm not sure its pulled in the same way the actual Netflix video player would do it.


you wouldn't pull at gigabits/s bandwidth when casually watching netflix


dunno about netflix, but youtube usually does. They send you a chunk of data as fast as possible, and then send nothing till your client requests the next chunk.

By doing that, they can get a good estimate of your connections available bandwidth, which is needed for the decision whether to automatically switch to a higher/lower quality feed.

It also means they can use 'dumb' servers which don't do any application-specific logic for throttling.


Recently I've noticed my phone disconnecting from my Wi-Fi router (a relatively underpowered device running OpenWRT and WireGuard) when starting YouTube videos. I guess this could explain it, if the router is hiccuping on that initial blast of data. I also use a Safari extension that lets me choose the YouTube video quality, so that might affect it if I'm not giving the feedback they expect for "auto" quality selection.

(The issue is not the router, though - this doesn't happen on my laptop. I think my phone is just more aggressive in assuming the Wi-Fi is down and it's better to switch to cellular. But couple that with my phone's policy to use VPN on cellular, and the switch becomes much higher friction. I tried simply disabling cellular data, but then it's even worse because every time the phone disconnects from Wi-Fi it pops an alert telling me to enable cellular data.)


makes sense, but in that case it's quite easy to distinguish between a burst of traffic of <1s to a speedtest that last tens of seconds
