Basically I've acquired a burner Android 8 phone and am running the target.com app which is the only way they let you get parking lot delivery at the store. I assume the Target app is spyware. I keep the phone powered off almost all the time which should limit the spying. The thing is, if I power up the phone and order something, then close the app, I still get an alert when the status of the order changes (e.g. it's ready for pickup). So the app is still listening for network traffic from Target.

Can anyone explain what is happening in Android and whether there is a way to make an app really stop? Does the app stay in a running state even after I've closed the UI part of it? Is there somethng like an inetd in Android that listens for network alerts and re-launches the destination app? Are there Android app permissions associated with this, that I can revoke?

I don't want to run this type of app on my main phone, but I had at first liked the idea of using a burner for such things. Now, though, I wonder if I need a separate burner for each suspicious app. Thanks.

Rating: 4.5/5.

I needed another headlamp and was familiar with an earlier, micro-USB, white-led-only version of this light. Build quality of both is fine, I'd say not fantastic but perfectly usable for not too demanding purposes, and a terrific value for the price. Claimed water resistance level is IPX6. Headband is comfortable given that this is not a tiny light. I think it is still small enough to not need an over-the-head strap. Weight is about 108g including battery and strap.

Wurkkos and Sofirn both sell these lights and I think I heard somewhere that the actual manufacturer is Boruit. There are various models with different configurations. The H25LR has one white led, one 660nm (deep red) led, and USB-C charging.

Order date: Nov 22 2024. Got shipping notice on Nov 24. Package delivered December 5, so about 10 days transit from China to California, not bad. Cost was $19.99 including an 18650 battery. Shipping was free due to order being above $19. This is hard to beat.

The included battery is labelled with Wurkkos branding and says 3000 mah. It is an 18650 button top. I didn't test the capacity or charge current, but I measured the length at around 66.5mm not including the button, with the button adding another 2mm or so. So maybe it's a protected cell, I don't know. The springs in the light are pretty stiff. If you loosen the "tail" cap by 1/4 turn or so, the light breaks contact with the battery, giving you a lockout from accidental turn-on and also from parastic drain. I tried swapping in an unprotected flat top battery and that worked fine including the lockout.

The UI is fairly sane given that it's a 1-button light with multiple colors and levels that doesn't run Anduril. Short click to activate white led at the same level as last time, long click for red, also at same level as before. Once either led is on, hold down button to cycle through 4 levels. I didn't attempt brightness or runtime measurements.

My general comment about the beam is that it's more directional that I'd prefer, particularly for close-up usage. This is for both the white and red leds. It's not terrible, it's just that I like floody beams for reading and fixing stuff.

The lowest levels of both leds are ok, not super low. Some people appreciate ultra low levels and I can understand that. These are just regular low. I find that level 2 of the white led is about right for reading, walking indoors in the dark, etc. The higher levels are there when you need them.

The red led goes from low to quite powerful, like several watts. I don't quite understand the purpose of a powerful red led. Does anyone really want long distance outdoor illumunation in deep red? I would have been fine with just the low level, or a redesigned light with two full sized white leds, plus an auxiliary small red led. The red led for me is for minimal disturbance to your own night vision and that of others around you. So it should be just bright enough to maneuver in the dark or see an object (telescope, say) well enough to reach and turn a knob. I don't remember ever wanting a bright red light.

There is a handy featue of an RGB led under the on-off switch. When you first turn on the light, that led acts as a battery level indicator (green=charged, etc.) and it stays on for a few seconds. Also, when you plug in a USB charger, it lights red during charging and green afterwards.

The instruction pamphlet says charging takes 4-5 hours, suggesting a 500 ma charge rate similar to the micro-USB version. I.e. it's likely to be the same charging circuit except with a USB-C connector. That is ok with me. The instruction pamphlet also amusingly says that questions and problems should be emailed to [email protected], heh.

A slightly more "premium" approach would be to include faster charging (3 amps) and maybe powerbank output. I do like lights with built-in chargers, as opposed to the kind where you have to remove the battery and charge it outside the light. Sorry about that, Hank ;).

Wurkkos now has the interesting HD10 Mini which is a 14500 powered anglehead flashlight / headlamp with Anduril, sort of like the Emisar DW4 but smaller. I don't really care for the 14500 battery type but it would be nice to have a lightweight 18650/18350 version of this light (the DW4 is too heavy). Or it would be of more interest if it could run on 1.5 volt AA cells in addition to 14500. As it was, I went for the 18650 version instead. For a lightweight headlamp I have a Nitecore HA11 and might get or concoct something ultralight at some point.

Anyway that's my new light day for now and it has been a good one.

Addendum (December 26): I noticed something interesting about the front of the light, center, above and below the main leds (see circled green areas in the pic). There are two milled slots that look like they were designed to hold tritium markers. I guess I'm off to mixglo.com to get some. I'll have to measure the slots but basically 2x5mm or thereabouts.

Update: Mixglo situation is that 1.5x6mm vials are $6.50 so two vials plus a $6 tube of Norland adhesive (1 ml) would total $19. BUT, Mixglo offers untracked shipping for $6 only if the order value is $15 or less. Otherwise you need tracked shipping which costs $22. It's cheaper to make two separate orders. I think I'll order one vial plus the adhesive, try to install the vial, and then order a second vial if the first one goes in ok. I'll update if and when there's a new development. Fwiw, tritiumworkshop.com (in the UK) is another well regarded source of tritium but it ends up costing a little more, depending.

Update 2: more careful examination convinces me that those little holes weren't intended for tritium but were just part of the heat sink-like styling. But, it should still be possible to do something there or nearby between the "fins", possibly with a bit of Dremel-ing. I want to take some caliper measurements before ordering vials.

That is, turned on its side so the display is vertical, using an external keyboard. I'm thinking of getting one of the Yoga models, which are naturally suited to that. I run primarily browsers, emacs, and maybe calibre, under Debian GNU/Linux. My questions:

1. Any issues getting the X server to work that way?

2. Any issues with cables having to stick out of the edges and poke things? At minimum a power cable, but i like to use Ethernet instead of WiFi when I can.

Thanks!

I took it out of my pocket and tried to turn it on, hmm, twist switch was rather tight. Tightened it down or maybe it was already down. It didn't turn on but I figured I maybe had left it on all night by accident and drained the battery. Started to remove the head and heard a popping sound. Battery (alkaleak but fairly new) had some kind of black stuff on the casing near the negative terminal, no other obvious damage to the light or battery. I put in a new battery => won't turn on. So I guess the circuit is blown.

I like the light and they are affordable so I guess I'll get another, but it seems like a shame that I don't see much of a way to repair it or scrounge usable parts from it. I will try to remove the circuit board when I get a chance. Not now though.

Oh well. Bring a spare.

People keep mentioning GraphineOS as a reason to buy a Pixel, but in other regards the Pixel hardware doesn't seem so great. If you get a different phone that can run Lineage, is Graphene really better? Thanks.

Samsung Galaxy XCover Pro 4G. From 2022 but there are newer models. So stop saying HUR HUR WATER RESISTANCE when people ask for phones with swappable batteries. This shows it can be done.

Edit: was $120, now sold out.

Many voters are willing to accept misinformation from political leaders – even when they know it’s factually inaccurate. According to our research, voters often recognize when their parties’ claims are not based on objective evidence. Yet they still respond positively, if they believe these inaccurate statements evoke a deeper, more important “truth.”
