I know desktop system JRE's aren't recommended any more, but there's still plenty of apps out there that require them. I literally ran into this last week. I am glad to hear the toolbar on the JRE is gone, and I'm glad t

If you want it to be recognized by the system as a valid runtime for Java apps, I believe it needs to be in /Library/Java/JavaVirtualMachines/jdk${VERSION}.jdk/Contents/Home/.

At least the MacOS binaries from Oracle are not packaged in a user-friendly manner. You just get a zip file containing JAVA_HOME, and it's up to the user to know what to do with this. Apple requires you to copy this to a very specific,

That's not entrapment. At least in the US, entrapment has to pass two tests: 1. Was it a crime the suspect was unlikely or unwilling to commit otherwise? (The "subjective" test.) 2. Did the actions of officers cause a normall

I have one of the few avalanche beacons that have separate modes for alkaline and NiMH batteries. (Specifically, the Barryvox Pulse.) My understanding is that "alkaline mode" measures the voltage to determine charge level, as one

This has been in place since 10.6 Snow Leopard. It's part of their built-in anti-malware system (MRT + XProtect + Gatekeeper). It's no different than a virus scanner auto-updating its signatures.

Yes, but it's an extra expense. If you've got spare USB-C chargers you could use, it's tempting to wait.

(a) A fuse only prevents over-current based on the port's rating, not the cable's. It wouldn't help here. (b) USB-C has several modes of operation. The thinner cables aren't under-speced in the lower-tier modes. They&#x2

Nope, none of the amateur bands allow encryption. There are “unlicensed” (technically licensed-by-rule) bands that do. Typically the ISM bands, which is what WiFi uses. But they aren't as open for experimental use as the amateur bands.

My understanding was that the drivers were originally added partly in response to the "Fremont Flyer" incident, where a test train under autonomous control drove itself off the end of the track: https://www.flickr.com&#

The radars can save lives by detecting an imminent collision and sounding an alarm ("pay attention!") or automatically breaking. The buttons on the steering wheel are also a safety feature, since it lets you keep your eyes on the

For international flights, they traditionally scan your passport at the check-in counter. As a US citizen, this is mostly just to validate any visa requirements for the country you're traveling to. However, for non citizens, this data

The TSA got rid of all the backscatter x-ray machines, so the body scanners aren't using ionizing radiation anymore. This was the biggest health concern with the old devices, and I was really glad to see those gone. The newer scanners

At the larger bay area companies, it's usually an entire office building dedicated to nothing but processing mail. Similar to college campuses. I think "warehouse" is an appropriate term in these cases. :)

If you remember the original iMac, they did the same thing with USB-A. Everybody was concerned that the iMac's only I/O port was USB (when others had serial, parallel, and maybe SCSI/USB as an afterthought), and it was comp

You are of course correct. But getting into the details behind MVNOs and roaming is a much more complicated topic than I'd want to type into a small comment box, and not really relevant to the issue at hand. :) My point is just that CM

Each provider uses a different cell tower (or at least their own antennas on a shared mast), with their own independent radio frequencies. "All devices in cell" is still accurate. Each cell belongs to a single provider. It's

Not mentioned in the article, but I'd also recommend force-setting DHCP Option 43 to "ANDROID_METERED" to let Android clients know you're on a metered connection (hotspot) instead of a normal landline-based WiFi network.

This is a great idea. I'll bring it up with the Android Studio team and see what we can do.

That method just instructs the OS to send keepalive packets on a system thread. It saves some CPU power by letting your process sleep, but still requires waking the cell radio up periodically. The implementation can be found here: https:&#

15-20 minutes for a high-priority FCM message isn't normal. Either your app is being rate limited by the server, or there's something unique about your network setup that is preventing push messages from getting through. There&#x2

GCM/FCM will delay low priority notifications, in order to batch as many together as possible. On top of that, the cell networks don't allow keeping a socket open for more than a few minutes without sending keepalive packets. Unli

Some of us were asking for this machine. As a developer who builds large, complex projects (it's not uncommon for a build to take 40 minutes on a 16-core Xeon workstation), the Mac Pro is exactly the type of workstation I'd be int
