Newer reviews can be expected to be ongoing projects, with minor additions or corrections.

Note: When I rate stuff, a 10/10 does not indicate perfect in an absolute academic sense, but as in (at least) as good as could be expected at the time, minor flaws allowed. For portable devices typically limited by the size and weight. Value for money also counts. An electronic device that got a high score in 2005, most likely would seem like pure trash ten years later….


  • More on Windows and scaling

    About a year ago I made a post on windows scaling

    So I tried to see if they have fixed stuff the past year – and NO it is actually worse now…

  • C# Set volume example

    It took me quite some digging to find a clean way to set the standard default volume without external libs. So here the result.

    If you do not want the console output, remove the writeline, and change the project from Console to Windows App.

    I suggest using it as a Scheduled Task triggered by connect to user session and/or similar.

    It is composed of a couple of bits and pieces combined/reduced primarily from these three.

    using System;
    using System.Runtime.InteropServices;
    namespace SetAudioLevel {
        class Program {
            [Guid("A95664D2-9614-4F35-A746-DE8DB63617E6"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
            private interface IMMDeviceEnumerator {
                void _VtblGap1_1();
                int GetDefaultAudioEndpoint(int dataFlow, int role, out IMMDevice ppDevice);
            private static class MMDeviceEnumeratorFactory {
                public static IMMDeviceEnumerator CreateInstance() {
                    return (IMMDeviceEnumerator)Activator.CreateInstance(Type.GetTypeFromCLSID(new Guid("BCDE0395-E52F-467C-8E3D-C4579291692E"))); // a MMDeviceEnumerator
            [Guid("D666063F-1587-4E43-81F1-B948E807363F"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
            private interface IMMDevice {
                int Activate([MarshalAs(UnmanagedType.LPStruct)] Guid iid, int dwClsCtx, IntPtr pActivationParams, [MarshalAs(UnmanagedType.IUnknown)] out object ppInterface);

  • BlackBerry Priv, 5¼days stamina, no tricks. Display on 50m/day

    The BB Priv has a pretty nice stamina, if it is not too infested with bloat (mine is debloated).

    Though some complains that a 3410 mAh battery is too small for a phablet with a 5.4″ QFHD display, it is enough for me.

    5¼ days on 96% battery

    This is with no trickery of radios off or similar. 4G, WiFi, NFC all turned on. GPS off though. ADD: BT off too.

  • Phillips BDM4350UC. Mini review. An even greater monitor…

    This 43″ IPS has substantially better viewing angles used close than its 40″ VA predecessor, but poorer blacks, otherwise much the same.

  • Android vs WPD bug. Wrong filesizes reported

    I stumbled upon a strange bug in what Android can report to e.g. Windows trough the MTP/WPD interface.

    Under some circumstances it reports a VERY wrong file size, but if you by WPD open a stream and copy the file until it sends no more bytes, it returns the correct full content.

Newer posting are in English (well sort of, bare with me, non-native…), some over five years old just a blunt copy of the texts in Danish.

Layout – and perhaps more translations (hopefully) will be improved later.


Collecting of old stuff started May 2015. Entries are generally attempted dated with original stamps, even if they are somewhat updated since, several reviews have been ongoing ‘projects’.
