Quicker posts, less retardation! One of the goals for 2021 was to 0. write more often, 1. faster after ‘doing’ and 2. therefore also covering more things which were ‘touched’
There’s still a pile of topics left from 2020 xD
In Novembre a colleague and me talked about one of his acquantainces which wrote an iOS-app, which can show how many “Corona Warn App”-users are nearby. I was puzzling over this and also wondered if really some special app or some bluetooth-receiver-tinkering is needed. I still own that one BT receiver for the Raspberry.
First: So, quick check for BT sniffers in the playstore showed RamBLE.
Second: 5 min of googling found the UUID used for the exposure notification: “fd6f”.
Quintessence: check the market before developing something 😉
aka: Accessing Redmine outside your local network via Android-app.
I set up port-forwarding via the router. Dynamic name is set via the Synology NAS.
So the url to use is: http://metrik.myds.me:5002/redmine
And after testing 5 (in words: FIVE!) apps with really mixed results, I choose:
Redmine Mobile app made Easy
The ‘magic’ behind 360° panoramas is nothing new. I remember stitching together manually the pictures from the Canon Ixus 800, later switching to AutoStitch and other solutions. But after I used Google Kamera as replacement for the pre-installed camera-app on the smartphone and also acquired a cheap 10€-cardboard I had a jaw-dropping moment of enlightment: wow! This is amazing. And to whomever I showed this (techies, friends, parents, ..) they were also impressed. A freely explorable panorama with head-mounted gear is soo much much descriptive of the scene than the regular 2D-photos. Yes, I still stick to analogue photography, but If you want to show somehow how the sights looked and how the surrrounding environment looked like, then stick to a panorama. Creating them is quite is, but this is a different story.
Since the discovery of the big vulnerability called Stagefright (summer 2015) some additional were disclosed. Time for an update of the already cyanogenmodded Galaxy S4.
Found a good description of what the names for the different gapps-packages mean: page (includes downloads). I choose pico!
- 5 min real work: get the ROMs, put them to the SD-card, boot into TWRP; select the nightly, then add also gapps-pico, wipe DALVIK, reboot
- 20 min waiting: after flashing for first boot-up (self-configuration) .. works like a charm
I just wanted to replace the OEM-Samsung Lollipop with the latest CyanogenMod-version on my Samsung Galaxy S4 LTE (GT-i9506).
So the simple plan was to: root the device; replace the ROM with CM12; add the Gapps-package; reboot and be happy ..
.. in the end I tried so many different ways involving Linux Mint, OSX 10.9 and Windows 7 as host-system; flashing via adb, heimdall and Odin; different nightlies and kernels; several gapps-packages and seven hours lifetime .. but I learned a lot 😀
- Win7: install Samsung driver; reboot, reboot, reboot
- root with CF-AutoRoot: guide // download – use “root checker” or some other app to verify the superuser-access before rebooting into download mode
- flash TWRP via Odin
- flash CM12-nightly: download
flash gapps: downloadflash minimal GApps: download (is without the useless crap)
- wipe cache/dalvik
- reboot and setup everything from scratch (or with some backups … you created some, didn’t you? 😀 I used “Easy Backup & Restore” – worked perfectly. K-9 Mail can restore itself ..)
edit: 20150724 replaced Gapps with “GAPPS minimal”; restored all settings, SMS, contacts, …
