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.

#3 is my script that converts one particular RSS feed to .ical format, and pushes it to a repo, because setting up a website for one silly script was overkill.

I was forced to code in Perl one time, there’s no way it could be good.

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.

I’ve achieved something today. Not anything useful, but still something.

Browser-based notifications are easy to turn off, and it’s probably the only way to get a message on a desktop PC without subscribing to email or using RSS. Also you don’t need to install an app on your phone.

Password strength is usually checked inside your browser, not on the server.

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.

Ah don’t worry, if you do fopen(file, "w") on Windows and forget to use "wb" flag, it will automatically replace all your \n with \r\n when you do fwrite, then you will try to debug for half a day your corrupted jpeg file, which totally never happened to me because I’m an experienced C++ developer who can never make such a novice mistake.

It depends on whether you are printing to a terminal or to a file (and yes the terminal is also a file), and even then you can control the flushing behaviour using something like unbuffer

printf is superior and more concise, and snprintf is practically the only C string manipulation function that is not painful to use.

Try to print a 32-bit unsigned int as hexadecimal number of exactly 8 digits, using cout. You can do std::hex and std::setw(8) and std::setfill('0') and don’t forget to use std::dec afterwards, or you can just, you know, printf("%08x") like a sane person.

Just don’t forget to use -Werror=format but that is the default option on many compilers today.

C++23 now includes std::print which is exactly like printf but better, so the whole argument is over.

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.

As long as your byte consists of 8 bits.

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?
