Your own currency devalues and thou have foreign currency debt. How to solve that?
Consider / suppose you are a bank, an entrepreneur or a state foreign currency loan of the Republic of Turkey!
Turkish lira TRX is currently devaluing against € or US $.
What can you do now?
Well you can of course reduce risk via a forex pair swap.
In case, that you want to hedge the risk (that TRY don`t fall to much against € OR US$), you bet on falling TRY/€ forex swap pairs in derivate secondary markets or if this doesn`t exist for huge amounts of TRY, than bet on rising up €/TRY US$/TRY for that case.
What will happen with that hedge?
In case, that TRY looses more value against € or US$, your risk reducing swap works in the opposite direction.
Your losses will be smoothed out straight.
Attention for case if TRY will regain value against € / US$.
If TRY regains value against € or US$, your foreign currency credit rate, will not become cheaper, because your hedge swap will loose for that case.
What we ignore in that simple example?
We ignore prime rate and credit rate changes, that could be triggered, when FED or ECB increases or decreases prime rates.
Kind regards,

How to install LineageOS on Alcatel1 (5033D)
0. Attention: You can destroy or brick your phone totally, if something went wrong.
Unless you don't exactly know all fundamentals about android adb, fastboot, boot process and slot A/B, please don't do this:
1. install adb and fastboot on your linux or windows system
2. Enable developer options by clicking 5x times on build number in system settings
3. enable USB debugging and unlock OEM in developer options and debugging options after you became a developer
4. follow now the instructions here to unlock your phone:
https://www.techdroidtips.com/unlock-bootloader-alcatel-1/
5. Download LineageOS either from:
5.1 Andy Yan's personal builds, e.g.: LineageOS16 OR
5.2 github phhusson OR
5.3 My Google Drive (You can find all diskdump images directly here)
6. connect your Alcatel1 to your PC
7. now use "adb devices -l" to see, if android Alcatel1 is present
7.1 if you use Andy Yan's personal builds or phhusson github, then "adb reboot recovery"
Wait until recovery mode is ready, then
- Wipe cache first
- Wipe data / factory reset next
- enable adb next
- load image from adb
- Under Windows or Linux type "adb sideload lineage-1*.img"
- modify the images by mounting them with 'mount -o loop path2image/file.img /mnt' under linux
- now you can modify e.g. the loopback mounted system.img for your own purpose.
- flush, sync and then 'mount -o remount,ro /mnt'
- look if all modifications are done well and then 'umount /mnt'
- now use adb shell to reboot to bootloader by "adb reboot bootloader"
- yet use "fastboot flash system path2image/system.img

Draft: Idea a multiple device dark net (.onion) cloud
We've Azure Cloud with microservices, we have amazon cloud, with finest virtualization, but both are companies under patriot act and safe habor agreement. Some months / years ago, there where a lot of tor (dark net) bridges and endpoints in both of those clouds, but if the stock owners decide to prevent TOR in future, you're totally pissed on and you have no legal ability against that.
So lets build a onion scalable cloud, that uses each device with less CPU load and some SSD or similiar fast disk, to build a docker / virtual machine dark net cloud.

Dysphotic Future with failing Anti-Terror AI
In a dysphotic future, there will exist an AI, who monitors all public, privat and even dark net communication and discussion bords and if the AI detects and emotional HATE-SPEACH or VERY DESTRUCTIVE post, then it automatically creates a news story about a crime (e.g. terrorist attack or assault, slaughter, rape), where the victim is a virtual person baseed an designed on the victim, who was blamed in the discussion board. The perpetrator is portrayed similarly to the person who posted / wrote the hate speech in the discussion forum.
The problem with this is that in this future there are regular articles about terrorist attacks and also a lot of rapes, e.g. if a man with women's problems expresses himself indulgently in a gamer forum.
Originally the purpose was to see emotionally unstable people for the ultimate dire consequence of their actions, but with this deluge of gruesome articles more and more dulled people and overlooked the warning signs of real crime.
[Das Problem dabei ist, dass es regelmäßig in dieser Zukunft, Artikel über Terroranschläge gibt und auch viele Vergewaltigungen, wenn z.B. ein Mann mit Frauenproblemen sich ablassend in einem Gamer Forum äußert.
Ursprünglich war der Zweck, emotional instabilen Menschen die letztmögliche schrecklichste Konsequenz ihres Handeln zu veranschauen, aber durch diese Flut an grausamen Artikeln stumpfen die Menschen immer mehr ab und übersehen die Warnsignale für echte Verbrechen.]

Frage zum musikalischen Urheberrecht
Suppose I take all the classical music compositions, that aren't subject of copyright (e.g. church modes, all modern classics before 1900, such as Bach, Mozart, ...) and use the minimum protectable tone sequences as a sample construction kit.
What is the amount of music that I can (theoretically) generate with these sample modules through combinatorics?
(I mean, what amount of music can theoretically be created with these samples as a basis).
Don't worry, there is enough material left for new composers, that want to produce under copyright, because all music that is not based on the classical notation system or pentatonic scale (such as 5/9 or 17/33 or other fractions of high prime numbers) cannot be reproduced with it.

Semantic web lost in history / herstory around 2010, how to reactivate it & a short contract use case
Current hypes, trends and pushed business models at 2020
Let's take a short look at the current hypes, trends and pushed business models for companies:
- IOT (Internet of things), Industry 4.0
Machines, units, etc. know and probably send their own status at manufacturer, service center, at home or somewhere else over the rainbow (in case of ugly DNS injection, warped rouing tables [OSPF, BGP] ot men in the middle [squid bump, bluecoat, ...]).
Those units normally,communicate when they need maintenance, when components soon needs to be replaced, when physical, technical or environmental critical limit reached, when subsystems fail or completley shut down, when the user when the customer operates it improperly or negligently, simply report in intervals that they are alive and everything's OK, , etc
We can find a lot of use cases for many useful applications here, added value / surplus is often small but still useful! Problems with security, flood of data, extracting relevant events and, above all, reacting to the corresponding message are the challenges here. - Cloud
I like the cloud, but sometimes cloud feels cloudy, cloudier, obscure dust and smog over keywords and hypes and real hard technical features that generate great customer surplius and real cash or quality of business benefits.
What are the most common problems, pitfalls and misunderstandigs with any cloud?- Lack of specific customer requirements and inaccurate, exact technical specifications from the cloud provider.
Practical example (what I really need and I'm thinking about right now):
I need to implement a state service, that saves current game status of small multiplatform games (e.g. card game schnapsen, archon clone, SUPU) in the cloud. If I play on my android tablet or smartphone, the current state and course of the game will be transfered to a cloud servie, persisted in a cloud storage or database and if I continue playing on Windows desktop, the last state of the game is automatically fetched from the cloud and the game application sets that game state and transferred back to cloud after the next move.
For my purposes the cheapest way will be sufficient:
A simple Amazon Linux 2 AMI (HVM), SSD Volume, Type t2.nano, t2.micro or t2.nano with a simple SQL-Database (no matter if hackish install at virtual imaage or the smallest Amazon DB instance) with somekind of open source PHP Swagger API, like https://github.com/andresharpe/quick-api
With similar requirements, some developers and most managers are probably unsure whether to use Amazon ElasticCache or some kind of Session State Server ported to Azure SQL or entirely another not well known cloud service.
Even fewer people (including myself) know what the exact technical limits of the individual services are, e.g. the exact performance and scalable elasticity of Anazon Elastic Cache and when scalability of Amazon Elastic Cache is completely irrelevant, since the network traffic and the network data volume will always be the bottle neck in that specific scenario. - Nice advertising slogan, but poor performance and poorly configurable options from drive and storage providers, no standard network mount (like SMB or NFS), but a lot of cloudy magic.
When I look at the beautiful Google Drive and Microsoft One Drive, I immediately see that this is not a classic network file system mount under my point of understanding.
Reading and writing large blocks or deep recursively nested directory trees is extremely slow.
I also didn't find an option to have an incremental version history backup created after every change (Create, Delete, Change) to the Cloud Drive or at least simply midnight-generated backups for the last 3 months at low cost.
Options like synchronizing parts of the Cloud Drive locally create horror nightmares.
In 1997 we booted an NFS from the USA via Etherboot with real-time DOS and debugged faster Doom Clones and other 3D games in C ++ with some ASM routines and the network performance didn't fail. - Difficulty finding the most suitable service in Cloud Djungel. Real technical comparisons between the hard facts and the possibilities of the individual cloud services have so far mainly published by free bloggers, e.g. AWS Lambda vs Azure Service Fabric
Decisions are more based on creeds (we have a lot of .NET developers, so we'll use Azure, I mah strong Amazon-like power women and Linux, so I'll use Amazon).
- Lack of specific customer requirements and inaccurate, exact technical specifications from the cloud provider.
Lets go back to RDF in the years 2010 - 2015
You probably know what semantic web, owl, rdf, machine readable & understandable data are, right?
If not, then here is a little bit of reading:
https://www.w3.org/TR/rdf-mt/
https://www.w3.org/TR/2010/WD-rdb2rdf-ucr-20100608/
https://en.wikipedia.org/wiki/RDF_Schema
What does 'going back in time' mean in a large scope and broader sense?
Before all the new trends, there was an attempt to realize semantic web, e.g. RDF as an XML extension with semantic machine-understandable properties.
When we as human beeings read a website or analyze BIG data, we automatically recognize the context, perhaps the meaning and probably the significance of this data.
Machines can't do that, they didn't have a semantic understanding until now.
Information theory distinguishes between 3 levels of information:
- Syntax level (compiler construction, scanner, parser, automata & formal languages, extended grammar, e.g. https://en.wikipedia.org/wiki/Context-free_grammar)
- Semantic level (meaningful reading by people, putting things into context, understanding contexts).
- Pragmatic level (goal-oriented action based on information by recognizing the meaning at the level of semantics).
I assume / postulate:
=> If computer programs reach 2. semantic level => then we are a big step closer to AI realization.
Why computer programs can't already implement semantic understandig?
Theoretically and also practically in terms of technical frameworks, computer programs are already able to understand semantically data.
The concrete problem is here, that too little data are provided in a semantically machine-readable form and a standardized (META-)language.
Somebody has to make here a larger startup, to transform already provided common and needed statistics public data in semantically machine-readable form.
What does that actually bring in return of short time invest?
Not so much immediately!
What could be the fruits in mid-term or in the long tail?
A lot, because when more and more public open data are availible in a semantic machine readable language, programs can also bring some of them in association and we'll be able to implement meta relational AI rules then.
Use case contracts
- employment contracts
- supply contracts
- service provider contracts
- insurance contracts
- bank contracts
- and all the contracts that people sign with just one click on a checkbox (which they usually do not know that this is a legal contract consent).
All clear and understandable so far?
I got this idea when I was looking and inspecting the adopted amendment to the laws and newly passed laws by the democratic republic of Austria and I wanted some semantic automated statistics for some use cases.

Schlafstörungen, nächtliche Recherche und IBM Security
Aufgrund nächtlicher Schlafstörungen recherierte ich ein wenig, denn für ein komplett neues android system image kompilieren, war ich trotzdem viel zu müde.
Dabei fand ich diese netten IBM Security Produkte und noch ein par andere Dinge:
IBM's still alive
IBM Security Trusteer Mobile SDK
Hier gibts so ein trusted mobile device (andoid, iphone, tablet) SDK (Software Development Kit), das Kompromittierungen (root, hacked, jail-breaked, untergeschobene root-CAs um SSL aufzubrechen und evtl. Staatstrojaner und ähnliches erkennt). Jedenfalls sollten Entwickler damit sicherere verteilte Anwendungen für Cloud u.s.w. hochverfügbar implemetieren können:
https://www.ibm.com/products/trusteer-mobile-sdkMobile device management (MDM) solutions
Das hier ist auch so eine mobile security Geschichte, die mobile Geräte Sicherheit der Mitarbeiter garantieren will. Also so kein "Nachhause-Telefonieren" durch irgendwelche untergejubelten Drittanbieter Apps, klassische End-2-EndPoint Secuirty, u.s.w.
https://www.ibm.com/security/mobile/mobile-device-managementIBM Security Products (case study fraud detection)
Dann zeigt IBM weiter noch, dass es auch eine standardisierte Fraud detection (wahrscheinlich generisch erweiterbar) kann! Ich schätze diese Fraud Detection Engine geht wahrscheinlich über Insolvenzregister, KSV, Casinosperre, Standardbonitätabfragen und dubiose exotische Prepaid oder sontige WireCreditCards hinaus und lernt kontinuierlich (à la Virenscanner):
https://www.ibm.com/security/productsnomachine.com
Zu guter letzt fand ich noch einen sicheren Terminal-Server (diesmal nicht IBM, den sich auch mal wer ansehen könnte):
