It’s supposed to be available on Android 15, but only on ‘select devices’, so probably only on Pixel.

Thanks for trying it.

You need to enter these commands in the Linux terminal app, not in the X server app. Once the two apps connect, it should be possible to launch another terminal inside the X server.

• Go to your phone Settings > About Phone and tap “Build number” seven times. You will receive notification that your phone now has developer options enabled.

• Settings > System > Developer Options > Linux development environment. On that page, tap the On/Off slider.

• You will find an icon for the new Terminal app on your home screen. It’s going to download 500 MB of data when you open it.

• Long-press the Terminal app icon, tap Info > Mobile data, and enable Unrestricted data usage.

• Now you can download more packages inside your Linux virtual machine using apt-get command, as described in my previous post.

Yup, Android is Linux, but you can’t run desktop apps on it like Gimp or LibreOffice or VS Code, that’s what Linux terminal is capable of.

Google’s bullshit strikes again! All apps must be built for Android 13 or they are removed from Play Store, apparently because Google could not do the Android security correctly for the first 12 versions. Now they can emulate Linux on Android, but cannot emulate an older version of Android on Android. And I last updated my app in 2021, during Android 11 era.

Here’s the link to sideload the app:

https://sourceforge.net/projects/libsdl-android/files/apk/XServer-XSDL/XServer-XSDL-1.20.51.apk/download

I’ll try to update it on Play Store tomorrow, if my crusty build scrips will work with the new Android SDK.

Someone who owns a fancy new phone with Android 15 or 16, could you please test if you can run GUI Linux apps on it using my X server app?

Supposedly it should work like this:

• Install and run XSDL app
• Go to home screen, open Linux terminal
• Run commands

sudo apt-get install task-xfce-desktop
export DISPLAY=127.0.0.1:0
xfce4-session

Open XSDL app again, you should see XFCE desktop environment with mouse cursor, and you should be able to launch Synaptic and install other Linux packages.

Is 300 nm the diameter of the optical cable? This terminology breaks my brain, 300 nm is 1000 terahertz, which is unreasonably large for a signal bandwidth, it’s like one milllion Ethernet cables.

That name was straight copied from

And the phrasing was intentional.

But it’s very convenient! When you have a BSOD, you don’t need your core dumped, you simply unplug your DRAM+ and send it to Microsoft using paper mail.

It’s way less expensive for state-sponsored hackers to blackmail your country’s official to leak backdoor keys than try to break the unbreakable crypto using a nuclear-powered GPU farm.

Saving arbitrary metadata is the exact use case for pickle module, you just put it together with your numpy array into a tuple. jpeg format has support for storing metadata, but they are an afterthought like .mp3 tags, half of applications do not support them.

I can imagine multichannel jpeg to be used in photo editing software, so you can effortlessly create false-color plots of your infrared data, maybe even apply a beauty filter to your Eagle Nebula microwave scans.

What, pickle.dump your enormous Numpy array not good enough for you anymore? Not even fancy zlib.compress(pickle.dumps(enormousNumpyArray)) will satisfy you? Are you a scientist or a spectral data photographer?

Yup. Now we have long-range WiFi filling that niche.

• They split off from Google.

• They are not using satellites, they shine a lazer from one fixed tower to another, with range about 20 km.

That’s because the article that started the whole argument tried very hard to present an expected behavior for embedded chips as a security hole.

Nope. You’ll only know how good is it when you run it on the actual hardware. Yeah you can install apps on Android emulator, but what makes or breaks custom ROM is driver support on actual hardware.

Should have used three spreadsheets. Excel tends to run slowly when a spreadsheet has more than a million cells in it.

There was no mention of over-the-air exploit, so eh.

Anyway, having direct unprivileged R/W access to platform memory is indeed a security hole, no matter the vendor.

It is not. ESP32 is an embedded chip with less than one megabyte of RAM. It cannot run apps or load websites with any malicious code, it only runs the firmware that you flash on it, nothing else, and of course your firmware has full access to every chip feature. If your firmware has a security hole, it’s not the chip’s fault.

My bad, I was talking about custom tabs, which are provided by Chrome or Firefox.

WebView is a separate app, and you can switch between WebView and custom tabs somewhere in system settings.
