iPhone 11 Pro battery is…

…quite amazing.

I’ve upgraded just before the Japan travelling to the current iPhone generation. I was expecting some improved battery life but I did not dare to think I would get THIS.

I’ve taken the last 3 generations of iPhones on trips to Japan and they all went through the same exercises and quite comparable day schedules.

The amount of navigation, screen-time, taking pictures and just browsing the web / translating led to all 3 previous generations to be out-of-juice just around half-day.

Not this generation. Apparently something has changed. Not really in terms of screen time – screen on-time got better, but not as great as the overall usage time of the device with screen off.

In regards of how much power and runtime I am getting out of the device without having to reach for a batter pack or power supply is astonishing. I am using my Apple Watch for navigation clues so I am not really reaching out for the phone for that. But that means the phone is constantly used otherwise to make pictures, payments, translations….

I am comfortably leaving all battery packs and chargers at home when all the time before I was charging the phones at lunchtime for the first time. I usually had to charge 2 times a day to get through.

With this generations iPhone 11 Pro I am getting through the whole day and reach the hotel just before getting down to 20%.

I am still using it all throughout the day. But this is such a relief that I am confidently getting through a full day of fun. Thumbs up Apple!

Calling Bullshit

The world is awash in bullshit. Politicians are unconstrained by facts. Science is conducted by press release. Higher education rewards bullshit over analytic thought. Startup culture elevates bullshit to high art. Advertisers wink conspiratorially and invite us to join them in seeing through all the bullshit — and take advantage of our lowered guard to bombard us with bullshit of the second order. The majority of administrative activity, whether in private business or the public sphere, seems to be little more than a sophisticated exercise in the combinatorial reassembly of bullshit.

We’re sick of it. It’s time to do something, and as educators, one constructive thing we know how to do is to teach people. So, the aim of this course is to help students navigate the bullshit-rich modern environment by identifying bullshit, seeing through it, and combating it with effective analysis and argument.

OpenFood Facts

Open Food Facts gathers information and data on food products from around the world.

To replace MyFitnessPal in our toolchain I am on the hunt for at least some quality food fact data.

The Open Food Facts data base seems to be one source – although in sparse and questionable quality (after first initial testing).

There is a comprehensive documentation about the fields of data supported. And there are several formats that the raw data can be downloaded in.

There are ready-made applications available as well. Definitly worth looking into further.

smart OpenVPN client for iOS

There is a free and well integrated OpenVPN client for iOS devices already. And as much as this one works quite well it’s also lacking some comfort features that are now made available through alternative iOS client implementations of OpenVPN.

OpenVPN is an open-source commercial software that implements virtual private network techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.

Meet Passepartout. The iOS OpenVPN client that comes with lots of comfort features. Of main interest for me is that Passepartout is aware of the connection you’re currently using and can adopt it’s VPN tunnel status accordingly.

Passepartout is a smart OpenVPN client perfectly integrated with the iOS platform. Passepartout is the only app you need for both well-known OpenVPN providers and your personal OpenVPN servers.

collection of pure bash alternatives to external processes

The goal of this book is to document commonly-known and lesser-known methods of doing various tasks using only built-in bash features. Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster. I came across these tips and discovered a few while developing neofetchpxltrm and other smaller projects.

eXoDOS

eXoDOS is an attempt to catalog, obtain, and make playable every game developed for the DOS and PC Booter platform. Striving to find original media rather than using scene rips. This collection uses a combination of Dosbox and ScummVM to play these older titles on modern systems. All required emulators are included and have been setup to run all included titles with no prior knowledge or experience required on the users part.

This pack includes 7,000 DOS games. The focus is on games that were either released in English or are fairly easy to play without a knowledge of the native language. This is not every DOS game ever made, however it is a very high percentage of all commercial releases. There are thousands of freeware, homebrew, and shareware games that will continue to be added in future packs.

The games have already been configured to run in DosBOX. Games which are supported by ScummVM will give you the option at launch as to which emulator you would like to use.

the big list of RTL-SDR supported software

RTL-SDR is a very cheap ~$25 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge.

The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it was found that the raw I/Q data on the RTL2832U chipset could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a custom software driver developed by Steve Markgraf. If you’ve ever enjoyed the RTL-SDR project please consider donating to Osmocom via Open Collective as they are the ones who developed the drivers and brought RTL-SDR to life.

And since the hardware is so affordable there’s lots of software and therefore things that can be done with it.

reverse engineered Gameboy CPU

This repo contains an annotated overlay for the Nintendo Game Boy DMG-CPU-B chip die and the extracted schematics.

This was done manually with only a few automated checks so THERE’S A HIGH RISK OF ERRORS. I’m in no way responsible if you made someone’s life depend on this and it fucked up.

Google Maps now allows offline maps for Japan (!!!)

For years now Google Maps did not allow us to download Offline Maps for Japan. It is an extremely useful feature when you are out and about and you might not yet have full mobile coverage or your plan is not set-up yet.

A week ago this was not possible and I have just now noticed that you can now select the Japan area for a custom offline map in the Google Maps app on my iPhone and on my iPad.

This is great news! Do you use the offline map feature?

procedurally generated cities

This application generates a random medieval city layout of a requested size. The generation method is rather arbitrary, the goal is to produce a nice looking map, not an accurate model of a city. Maybe in the future I’ll use its code as a basis for some game or maybe not.
