An experiment in AI-generated hybrid art based on my Touhou Project fan art.

 



* AI hybrid experiment*
Asked ChatGPT to redraw some unfortunate illustration with critical mistakes. 

A set of these illustrations is a redrawn version by ChatGPT, of the following works
https://www.pixiv.net/en/artworks/120485457 
https://www.pixiv.net/en/artworks/119309631

Used in these short films: 


My feedback on AI art (both pure and hybrid):  

This is actually my first attempt at creating AI art. However, rather than instructing an AI tool to generate artwork via a command prompt—such as using Python in Stable Diffusion—I used an illustration I had already created and had the AI—ChatGPT, in this case—process it.

It is an interesting experiment to upload my already made images to an AI tool such as ChatGPT to redraw it. The AI corrects the crucial mistakes I have made while transforming to a popular art style. It can be useful for cases like 

  • Reusing a piece of artwork that was compromised by a critical mistake or a lack of technique.
  • Facing constraints in time and energy when producing multiple pieces—for example, when creating a film.

The drawback is losing my style of characteristics in these arts after the AI process. While observing various AI arts, the art style of these AI tools seems to be quite unified to the certain extend. AI is still generally limited to reproducing art styles that are well represented in its training data such as historically famous or currently popular arts. Because a unique art style of the user is usually undermined, it is not suitable for creating one piece of their impressive art.   

Furthermore, only a very limited number of files are available process with these AI tools for a free option. It can be far less efficient to continue processing an image with AI in order to achieve the desired result than simply using traditional hand-drawing techniques.

In conclusion, AI art in any form has pros and cons. It depends on its application and the characteristics of the user's art skill. I may use the AI in some situation such as when I need a mass production of images. On the other hand, I am confident in my own drawing technique even though it might not perfectly match with what the popularity requires at the moment. Moreover, I am passionate to keep practising and improving my art technique. Hence, the AI process is useful as a supplement; not a substitution. 

 

The films with these AI-hybrid except for the last GIF (my original)



 Another attempt done on 22nd June 2025: 


This is what I have asked ChatGPT to redraw one of my illustrations. ... Well, my favourite characters, Myonchan (Youmu) and Sanae-san, are adorable. However, there are things making me really unhappy e.g. Sanae's hair accessory is not a frog shape. The shapes of Youmu's Roukan-Ken (supposed to be a long sword) and Hakurou-Ken (supposed to be a short sword) are distorted and placed wrongly. 


 
 

 This piece is the best ChatGBT's modifications of one of my illustrations I have recently tried. This is the image of my favourite Touhou character Megumu Iizunamaru, a Daitengu, with her fellows crow Tengus Aya Shameimaru and Hatate Himekaidou. Their outfits follow the original setting. Also, they are drawn to be attractive with this background. This is posted on my pixiv page: https://www.pixiv.net/en/artworks/131875650

Manifesto Fictosexualism!

 

I would like to declare for the manifesto insisting on the rise and the full right of Fictosexualism! 

This is one of the glorious cause of supporting Progressive Libertarianism /  Classical Liberalism!

I follow the ethics of my admirable philosopher Jeremy Bentham saying "The greatest sum of pleasures with the lowest sum of pains is the principle of moral and legislation." Nobody harms and an individual gains the happiness from being fictosexual!

I sincerely despise the staunch Christians, feminists, and the staunch structuralists, persecuting my personality trait!

Serious cyber incidence: Nico Nico Douga system down

 

The whole system down of Dwango Co,. Ltd. & Kadokawa group is a serious incidence especially in Japanese network. All the websites and the whole network server of Japanese video posting sites Nico Nico Douga (the potential competitor of YouTube) is completely down, and the recovery will take at least 1 month plus. This cyber incidence should be considered as a national cricis of Japan as Nobuhiro Tsuzi, the outsourced agent of the cyber security department of Japanese police, and Hiroyuki Nishimura, one of the initial founders, say. The vulnerability of Japanese server centre and the cyber security is questioned. Also, the shut-down of Nico Nico Douga causes the significant loss of the opportunity for the market competition and the entertainment creators. There are also various resources of BGM and pictures shared among many creators including YouTubers are stored in Nico Nico sites. Mr Tsuzi and Mr Nishimura, one of the initial founders, suspect it will take more and this cyber incidence is considerably serious.

My Python in practice 20221022

My wee Python programming to simulate Money Supply ⇒ Interest Rate ⇒ Investment volume. I am practising with applying my Python lesson to some sort of simulation modelling instead of just memorising it!

def Y_Inv(MS,Y):
    r_MS=pow(MS/10,-1.05)
    return pow(Y,-1*(r_MS))

for MS in range(1,100):
    print(Y_Inv(MS,100))

 

The followings are the breakdowns: 

 

# Liquidity(Money Supply) where Money Supply is i in range ():
def r_MS(MS):
    return pow(MS/10,-1.05)

for i in range(1,100):
    print(r_MS(i))



# Liquidity(Money Supply) where Interest Rate on Money Supply = Liquidity is i in range () WITH GENERATOR:

def r_MS(MS):
    yield pow(MS/10,-1.05)

for i in range(1,100,10):
    print(r_MS(i))

next(r_MS(i))


# Lambda function example of Interest Rate on Money Supply and Income of Investment on Interest Rate (on Money Supply = Liquidity) and Income fixed:

r_MS= lambda MS: pow(MS/10,-1.05)
Y_inv = lambda MS,Y : pow(Y,-1*(r_MS(MS)/10))

print("Interest Rate by Money Supply is", r_MS(100))
print("Income by investment is", Y_inv(100,100))



# Higher function of Income of Investment on the Interest Rate on Money Supply = Liquidity:

def Y_Inv(MS,Y):
    r_MS=pow(MS/10,-1.05)
    return pow(Y,-1*(r_MS))

Y_Inv(100,100)



# Income of Investment on the Interest Rate on Money Supply = Liquidity

def Y_Inv(MS,Y):
    r_MS=pow(MS/10,-1.05)
    return pow(Y,-1*(r_MS))

for MS in range(1,100):
    print(Y_Inv(MS,100))

 

# Income of Investment on the Interest Rate on Money Supply = Liquidity WITH GENERATOR:

Low-tech firms should rather adopt the public cloud!

Many small and medium companies as well as public institutes of the local authorities tend to be reluctant to adopt an advanced information technological (IT) apparatus such as the public cloud service due to their cost concern as well as their conservative characteristics. They tend to assume that they will not take an advantage of the large scale of economies offered by the public cloud service. However, these firms are actually those which will take a considerably high benefit of using the public cloud service. It is explained with the example of using Amazon Web Service (AWS).
 
The first issue is the version update including the cyber security. The average cost of the version update is heavier for smaller firms so that it is actually more cost efficient to rely on one unified provider. AWS updates their versions of the physical machines as well as the cyber security measures adapted to the latest requirements for the most recent environment for their entire global network. Furthermore, some of the security package, such as AWS Shield, come as the standard package.

 
The second issue is the maintenance of the physical apparatus in their on-premises environment. These small companies and relatively IT illiterate local authorities tend to often neglect properly looking after their on-premises environment and maintaining its durability. Moreover, they tend to be more prone to natural disasters striking their place. All in all, they had rather better locate their electrical data while implementing their cross regional redundancy of the entire database in case of a disaster and a cyber security threat.
 
Regarding their data management, AWS offers various types of database (DB) depending on conditions and usages. Amazon Dynamo DB handles non-structured data with a large volume so that electrifying the information is flexible to query and store. Amazon Aurora is autoscalable across the multi-regions so that the data redundancy is guaranteed in case of various disasters and the access overflow undermining the data-handling capability.
 
If they are worried about moving their data at once, AWS offers the data migration services such as AWS Snowball and AWS Snowmobile (called AWS Snow-family overall). These offer the option of outsourcing the entire data migration from their on-premises to AWS server network. Perhaps, these small and medium companies as well as the local authorities had better migrate the entire data and maybe the entire IT configuration to the public cloud in order to cut their expenditure for their IT staff as well as their physical space and apparatus.
 
There are still many individuals worried about the privacy and the countermeasure against the data leakage. Nevertheless, storing data in their nondurable vulnerable on-premises environment seems to be far riskier than outsourcing the database and the storage to the public cloud vendor. In addition, the scalablity and the redundancy across the regions enable to flexibly link and query the data across various places at any time available. Therefore, it is also expected to improve their administrative efficiency too.

The AWS IoT architectural plan for manufacturering companies

 

While working for various manufacturing industry, it is often wondering whether their administrative processes can be more efficient. They had better adopt the internet of things (IoT) and the cloud data management. These manufacturers and their retailers should take an advantage of the currently available public cloud technology as the means of the digital transformation (DX) which national governments frequently put emphasis on nowadays.
 
There are still many manually carried out tasks in a manufacturing business. There are too many repetitive input and output processes which can be reduced by sharing the database via the globally connected public cloud network. Furthermore, by applying the artificial intelligence (AI) and the statistical inferences using the shared database, it will instantly optimise balancing the available supply of production and stock and the demand from the purchase order.
 
Let’s examine the possibility of the IoT tool for the manufacturing industrial DX with reference to Amazon Web Service (AWS), the public cloud infrastructure provider accounting for the largest public cloud market share at 33%. The whole company group across regional and even national borders can share the same Amazon Elastic Computer Cloud (EC2) and various types of databases such as Amazon Relational Database Service (RDS) for structured data and Amazon Dynamo DB for non-structured data inside the AWS network. In addition, various advanced technologies for gathering streaming data, big data analysis, and the artificial intelligence (AI) based deep learning are available.
 
Sharing EC2 enables all the members across the borders to access applications and data installed into the shared platform inside the public cloud infrastructure. This prevents the repetitive processes of forwarding data between the departments by logging in from each location. Vendors outside the company group can also directly access the platform within the restriction by the information privacy. Moreover, the risk of causing the security hole of the entire network can be mitigated under the unified cyber security tool and various firewalls already prepared by the AWS instead of expecting all the departments to look after under their own responsibility.
 
Please kindly refer to this architectural map to read the following parts.
 
Amazon Kinesis can collect the real time streaming data from a factory to send this data to the IoT device set. This IoT devices prepared in the public cloud enable to control and monitor the production line and the storage conditions by simultaneously referring to both the external and the internal data timely delivered to the production site. There is also the correlational data-analysis estimating the potential influence over the storage volume and the quality control in advance. Thus, this is expected to prevent some critical supply management errors such as mismatching the recorded data and the actual data.
 
The information related to the product supply is then forwarded to the database. The database also simultaneously collects the purchase order data processed the retail management side. Then, AWS Lambda analyses these simultaneously collected data to send to the AI module called Amazon SageMaker offering the deep-learning analysis of various factors. Instead of allocating the costly human resources for bridging between the production site and the customer side, this automated data-link is expected to instantly match the supply requirements with the timely demand requirements without the conventional time-consuming negotiation.
 
Amazon SageMaker, the AI module, connected with the big data of the business is expected to enable this manufacturing business to optimise both demand and supply simultaneously at an instant pace. The production supply and its logistics can be optimised by referring to the customer demand trends and the exogenous factors influencing the supply quantity and quality.
 
These simultaneous data analyses can instantly offer the timely business management reports by using the database specialising in the graph presentation with some analytic footnotes such as Amazon Neptune and Amazon Redshift. This automated process can eliminate the conventional repetitive manual workloads. Moreover, it helps their management decision process with a fast objective report purely based on the mechanical data analysis because this new reporting system prevents the human bias and errors.
 
Regarding the customer relation, the manufacturer may directly contact to and deal with their customers via their own retailing website which can be directly connected to the entire supply management system equipped with the IoT devices and the big data analytics. They may no longer need their retail specialist agents negotiating between the manufacturer and their customers. All the conventional middle-men jobs are automatically carried out within the entire public cloud architectural mechanism with little humans’ help.
 
This autoscaling mechanism of the public cloud can instantly adjust the customer service costs depending on the real time demand volume. The conventional way relying on the contracted retailers requires to keep paying the agent fee regardless of the sales shortage. Furthermore, this conventional way cannot catch up with the suddenly but temporarily increasing sales volume. The human retailers are unable to be scaled up/down instantly like machines. By contrast, this new system is literally the machine base with the excellent scalability! Therefore, there is neither excess nor shortage of the product supply volume regardless of any demand level on spot.
 
Overall, this public cloud provision is efficient by means of not only time-wise but also cost-wise. It reduces the reliance on humans’ intuition requiring the long-term experience as well as the complex human relationship easily causing some corruption issues.

Cloud Revolution !

When I started knowing the existence of the public cloud services such as Amazon Web Service (AWS), Microsoft Azure (MS Azure), and Google Cloud Platform (GCP), I realised that it would be a remarkable innovation enough to be called revolution. Revolution alters the socioeconomic structure even including the infrastructural fundament and the ethical code. As same as the political revolution, the introduction of the public cloud is the business revolution!

First of all, the biggest impact is that there is no computer room containing servers, database (DB), and their network side a company office by using the public cloud service. These physical devices are located in the remote centre owned by the public cloud vendor so that they are simply outsourced.

This is advantageous for the accounting administration because it can avoid the capital expenditure and tax levied on it. In addition, its charge is based on pay-as-you-go so there is little need for preparing for the estimated volume usage. There is neither dead-weight loss of not using the computer enough or lacking the computer capacity due to the sudden heavy traffic while running a business.

The initial investment for the capital expenditure often challenges new entrepreneurs establishing their new firm. This factor used to discourage newly entering entrepreneurs from starting their own business. However, the public cloud has eased starting an entrepreneur to flexibly open their new business since its emergence. It is almost like a miracle enabling an individual to directly connect to the already configured server network without building her/himself!

In the past, starting a new business alone used to be considered as reckless. It used to require a reasonable size of the company office and more than one staff to operate a new business in order to maximise the full potential of the capital initially invested such as an office and devices. By contrast, the public cloud allows to start a business without any preparation for both devices and their space. Therefore, this is indeed a liberation for a lone entrepreneur from the territorial pressure and the labourers’ riot!

Another advantage for this entrepreneur is that s/he can flexibly travel around the world as long as it is connected to the public cloud service. No office at a fixed place is required to sit in! This entrepreneur can travel freely and budget her/his budget more flexibly without being bound to looking after a physical property. It emancipates an individual from the landlord’s rent seeking oppression!

In conclusion, the public cloud usage is indeed a revolution replacing the already obsolete norms and values in the entrepreneurship! Because big companies employing individuals are no longer able/willing to employee them to look after, it may be more important for them to start their own business instead of expecting these companies to hire them.





 

Anxiety

 Anxiety is haunting me, and also many others, nowadays. In particular, anxieties about the future prospect such as financial anxiety are the crucial problems. Unfortunately, it is certain that the material well-beings of majority individuals will continue declining. In terms of the economic analysis as well as the astrological analysis, the near future outlook looks very gloomy for certain. Thus, the world society will furthermore require us to be stoic rather than being optimistic.

Focusing on the economic analysis, the market multiplier is slowing down despite the continuous remarkably rapid technological growth especially for the information technology. There is a strange dilemma in the labour market: There is a skilled labour shortage while misemployment and unemployment are considered to be high in the labour market. This labour market mismatch combined with the stagnating income and investment distribution flow discourages the social mobility as well as the income gaining opportunity of individuals wishing to improve their lifestyle.

Focusing on the astrological analysis, the world will be in the recession by 2024. Currently, Uranus is crossing the ascendant of Taurus, the detrimental sign of Uranus, until 2024 as well as forming the square aspect with Saturn crossing Aquarius, the own sign of Saturn for these years. This infers that the socioeconomic stagnation is really severe at least until 2025. Furthermore, Pluto is going to start crossing the ascendant of Aquarius for 18 years from 2023 onward. Aquarius represents equality of outcome and justice as well as individual freedom under restriction and some degree of traditionalism. Aquarius is forming the hard aspect with Taurus (Economy), Leo (Political Power), and Scorpio (Intimate relationship) so that the socio-economy will shift from the centralised active globalist form to the decentralised less active form.

Considering these two analyses, it will be wise to become stoic to keep our lifestyle as humble and cost-efficient as much as possible than aspiring to expect for a lucrative lifestyle in the coming age. Stoic ethics may become worth off to refer to as our life instruction guidance then. The modernity characterised with the intensive Yang (bright) element is ending so that the Ying (shadow) element is being intensified as the reaction. Instead of wanting more, we are more required to wanting less from now on. We must accept various pains as they are instead of regretting for them. We also must accept the fact that the capability of solving problems for all of us are limited by means of our physical strength, social status, and external environments. Therefore, there are various things outside our own responsibility so that it is important to excuse for our inability.

Sum up, the anxiety will never seem to disappear because the drastic lifestyle change will certainly take place in the near future. The antidote against this anxiety may be being stoic enough to keep our lifestyle humble and cost efficient as well as not bearing the full responsibility so that it is important to rely on the public support. Hence, we had better simply accept that it cannot be helped so much.

The Cloud Types, the VPC, the public and private subnet, and the DMZ

 

In terms of the on-premises computing environment, the ownership of the physical computer device belongs to the user. However, an antinomy of the on-premises computer is not necessarily the could computing. There are two spectrums: The one determines where the device ownership belongs to, and the other determines where this device actually located in.

The ownership of the rental server belongs to the provider even though it is leased to be located inside the user's property. The clouds are distinguished between the private cloud and the public cloud depending on their ownership: The former belongs to the user whereas the latter belongs to the provider meanwhile both are located on the place distant from where the user is physically at.

The private cloud is established by an individual firm under its own responsibility of its maintenance and security update as well as its own exclusive right of using and modifying it. It also secures its privacy unless it is infiltrated by some wrongdoers with their hacking and virus attack. The disadvantage of owning the private cloud is its cost inefficiency of their maintenance and various updates including the cyber security.

For a relatively small-scale private ownership, the operation inside the on-premises can be achieved with the smaller budget than establishing its own private cloud. The cloud facility requires a bigger scale maintenance and update so that the private cloud may be more suitable for a huge organisation to handle. Nevertheless, even for a huge organisation, it will be more cost efficient to outsource the cloud service to the cloud provide specialising in the cloud computing provision.

On the other hand, even for a small-scale usage, the public cloud is useful because the user does not need to be responsible for the whole physical machinery maintenance unlike the private cloud. The user can simply subscribe the service instead of purchasing the entire package of software and device. Furthermore, instead of incurring the capital investment expenditure, the user can include the usage cost as the variable operation cost so that it is efficient by means of their administration accounting and tax payment. 

To take an advantage of the cloud computing, the public cloud is more likely to be cost efficient than the others due to its scale merit and its capacity. The major public cloud providers in the world are Amazon Web Service (AWS) (33% market share in 1Q2022), Microsoft (MS) Azure (22%), and Google Cloud Platform (GCP) (10%). These providers specialise in the cloud computing provision including specialised customer-support, maintenance, security update, product improvement, and the new product instalment. 

To use the public cloud service, the user selects which region to use. Then, this user is offered to use one or the multiple Availability Zone (AZ). Inside one AZ, the user determines the number of subnets to use where each subnet size is determined by a block of the IP address size determined by the CIDR (Classless Inter-Domain Routing) notation.

While using the public cloud, there is a service securing the privacy and the security of the server instances and the other services as though the user were using them inside her/his own private cloud network in an AZ. This is called the Virtual Private Cloud (VPC). Each subnet can be allocated inside the VPC while these subnets are usually categorised into the two types: the private subnet and the public subnet.

Instead of risking all the subnets facing both the infiltration risk and the overflowing access, it should allocate some subnets specialising in filtering these accesses as well as analysing their characteristics and traffic volume. Therefore, there needs a buffer demilitarised zone (DMZ) between the inbound accesses from outside the VPC and the private subnets inside the VPC so that the public subnet is allocated there between the gateway of the VPC and the private subnets. The public subnet and the Firewalls such as the Network Access Control List of AWS stand there to form the DMZ as the front-line defending the architecture behind. 

Placing only one network Firewall eases the infiltration of the intruders as well as the sudden access traffic overflow undermining the entire architecture configured inside the public cloud. The first line Firewall is set in front of the public subnet. The second line Firewall is set between this public subnet and each private subnet. The DMZ is the zone between two Firewalls where the public subnet bisecting these two Firewalls.

In AWS for example, there are the Load Balancers (LBs) with different task for each different duty. These LBs are in chage of equalising the divided traffic volume to each of the server instance to prevent them from receiving the excess volume undermining their performance. The Application Load Balancer (ALB) is often placed in the public subset distributing the access traffics to lead them to each destination connected to the private subnet areas. The Network Load Balancer (NLB) is often placed in the private subnet distributing the access traffics to lead them to each server instance depending on the traffic volume of these accesses to each instance. 

Because these LBs do their multitasking of not only balancing the traffic volume to each instance but also the health check of each instance to detect whether or not is capable to receive the access.  Therefore, the division of labour among these LBs becomes necessary to protect the entire architecture inside this network from the asymmetric or malfunctioning access traffic to this network.

In conclusion, it seems to be the trend of shifting the ownership of the computing system. Big organisations such as not only major private corporations but also government institutes have also started being more reliant on the public cloud. Small enterprises also take an advantage of this trend: By switching their main computing environment to the public cloud, they no longer need to deal with preparing for the spare, the physical devices, the cost payment for them, and the uncertainty of the future cost and benefit estimates. This is because the outsourcing of the autoscaling capacity as well as the physical and security maintenance to the specialist provider solve these issue. Hence, it is predicted that the public cloud provision will be popular more and more as the time passes.

Networking, Protocols, and Domain Name Service (DNS)

 


The letter "HTTP" found on the URL (Uniform Resource Locator) while surfing the internet is the abbreviation of the Hyper Text Transfer Protocol. There is a term "IP address" required for the internet access, and the IP is short for the Internet Protocol. These are the protocol of transferring data via the network connection: the IP is for the internet layer and the HTTP is for the application layer. There are also the other various networking protocols. The layer structure description here mainly follows the OSI Reference Model.

 
The protocols for the application layer are not only the HTTP but also the FTP for the data transfer to the file server, the POP3 for E-mail, and SSL/TLS for the data transfer with encryption for example. The AWS network architecture provides the ostensible sample. The Application Load Balancer (ALB) deals with the internet-facing side of the traffic with the HTTP to the public subnet directly connected to the internet to distribute the traffic access volume to those inside the public subnet. The Network Load Balancer (NLB) deals with the internal side of the traffic with the SSL/TLS to distribute the traffic access volume coming from those in the public subnet to those inside the private subnet. 
 
The SSL/TLS is the protocol also used for the transport layer connecting between the application layer (via the session layer and the presentation layer) and the network layer. The network layer represents the inside network of the on-premises environment connecting the physical layer via the data link layer. The network layer requires its protocol for its data transfer among these physical devices by linking their data together. The network layer is the gateway to outside the on-premises via either the internet connection or the Direct Connect via the transport layer, and this requires the protocol too.
 
 
As shown in the the URL, the HTTP is followed by the domain such as "art-blue-liberalism.blogspot.com".  This is addressing the website with the name which humans are accustomed with while computers are not. Computers understand and process various tasks by means of numbers so they address the website by the number such as the IP address. 
 
Therefore, the networking needs the domain name service (DNS) resolving a name to numbers.  The DNS resolves the domain name such as "art-blue-liberalism.blogspot.com" to the IP address such as 192.0.2.1 in IPv4, and 2001:db8:0:1234:0:567:8:1 in IPv6 (Ref. Wikipedia).
 
There is the DNS allocated in order to transform to manage the domains and the IP addresses among these access connections.  It is similar to the phone book while looking for a telephone number by searching the name of a person or an organisation in the index.
 
The DNS server checks its own cache memory to find an IP address for the domain name when it receives the query. If not found there, then, this query is sent to the root servers, the root of the DNS hierarchy, which are operated by a number of the organization and evenly allocated in the world. But, instead of directly providing the DNS server with the IP address, the root server requests the Top Domain Server (TDS) to instruct the DNS server to find how and where to look for the IP address matching with the queried domain name.

Database and Storage

 

The main components of computer are Central Processing Unit (CPU), Memory, and Storage. With comparison to human brain, CPU is the core part in charge of thought processes, Memory takes part of the short-term memory assisting these processes, and Storage covers the long-term memory storing information about experiences and knowledge. The computer server is composed of them while proportion of each component depends on the work duty of each server. A personal computer (PC) contains these three components together with a smaller scale inside it. People are often confused with the difference between the database (DB) server and the storage server because they tend to think both functions are the same or similar to each other whereas they take a part of different roles from each other. 

The DB server deals with sorting the data which must be ready to be downloaded, uploaded, and queried at any time the task is carried out inside this server network. Its weight on CPU and Memory is relatively higher than the storage server specialising in Storage. The DB server needs constant electricity supply all the time for running its CPU and Memory. There are basically two types of database, the vertically scalable database for the structured datasets, sorted out by the specialised programming language such as the Standard Query Language (SQL), and the horizontally scalable database for non-structured datasets. The former is good at the complex processes of handling the datasets required to be properly structured whilst the latter is for handling the multiple kinds of large datasets together at once. There are also furthermore specialised DB servers for such as data analysis, chart creation, data transfer, and data warehousing requiring a complex data query. In particular nowadays, the big data handling is so demanded all the more that an independent DB function each purpose is necessary to equip. Therefore, each independent DB server for each specialised task is more required than before. 

The storage server is for storing various sorts of information including the information of the already processed data and the archive memories of any workload of the entire server network. Although it does not need a constant electric supply, there is a required process for querying the information query. For example, with reference to Amazon Web Service (AWS), Amazon Athena, the interactive query service applying the standard SQL for analysis, is used for calling the storage service of AWS called Amazon Simple Storage Service (S3). The snapshots of various archives are stored there as a backup for a sufficiently long time period, which requires the process for restoring them. The logs of actions taking places in a server network are often stored in the storage service because the quantity created for the logs is huge and they have to be stored without being modified for a long-term. A static website, not needing a constant feed of streaming data, can be located in the storage server such as Amazon S3 instead of the server instance such as Amazon Elastic Computer Cloud (EC2).

Overall, focusing on the difference between their tasks, it clarifies the difference between DB and storage specialising in their own unique tasks borne to each other. Specialised DB is demanded for various specialised data handling tasks. Various compliance issues demand a durable storage capable to store the information set with a substantially high volume in a sufficiently long term. The key to understand it is to understand the factors of these computer components.

As a service (●aaS) via the public cloud

 

The information technology (IT) services are categorised into various levels nowadays. At this time, the business models providing customers and clients with the services via the online connection such as the internet rather than using services only within the on-premises environment. Most notably, there are three categories of services, the software as a service (SaaS), the platform as a service (PaaS), and the infrastructure as a service (IaaS).

Nowadays, many IT service providers offer the subscription service available online rather than the offline purchasing. The notable advantages are agility, availability, and scalability of the resource preparation as well as reliance on the providers for the content and security update and the physical space saving for the physical stuff. The shared access offered by the public cloud is now popular than ever.

The internet connection is not only the online connection option. There is a service called the direct connect connecting users' computer and the server network of the provider located in a remote data centre. The internet connection requires to secure the connection security preventing various incidents such as data breach and information fraud as well as the available IP address allocated to this connection. Then, the direct connect service to the public cloud system is often preferred in order to keep the stable access with an efficient financial cost per use (the internet connection tends to be more expensive for a regular high volume information transaction). For example, there is a movement for various financial institutes to shift their crypto asset management from the internet connection to the direct connect access to the specialised data centre. 

The most familiar service may be the SaaS because it is convenient for users to start using it. The software is already prepared by the providers so that they can simply use the ready-made application and data by just accessing it. Many companies adopt the Enterprise Resource Planning (ERP) outsourced as subscribing to this service via online instead of purchasing cartridge, CD, or the licence cord offering the software product. The disadvantage is its inflexibility of customisation and modification of applications and data adapted to the users' own requirements and environments.

The PaaS offers a more flexible service for customising and modifying applications and data via the platform composed of the operating system (OS) e.g., Microsoft (MS) Windows, middleware, and runtime is ready. When MS introduced its public cloud service MS Azure, many people thought its compatibility with the commonly distributed OS, the MS Windows, would be high. By contrast, the operation system and its server network architecture may require more flexibility enough to customise their own platform. Then, the IaaS introduced in the next paragraph can be the option.

The IaaS has become popular for the IT engineers to install since Amazon introduced its public cloud service called Amazon Web Service (AWS). The notable benefit is reducing the workloads for maintenance and security update as well as saving space and labour for the physical infrastructure composed of servers, databases, and their network in their on-premises. It is even beneficial to combine the already established on-premises environment and the public cloud services as a hybrid. Another notable useful point is Autoscaling elastically adjusting the volume use by means of its fluctuant demand, which is beneficial not only for the access and service maintenance management but also the financial accounting including the cost calculation and the tax payment. Because AWS was the first pioneer having popularised the public service, this seems to be the main business core of Amazon nowadays. 

In conclusion, considering these characteristics, it is predicted that more businesses will shift their IT basis to this "as a service" due to their convenience and resource scalability. In one of the Bank of England press conferences in 2021, the adoption of the public cloud services by many major private banks was hotly debated. Regardless of its controversy over the national compliance issues, it seems to be the unstoppable inevitable phenomenon across the border in 2020s like the globalisation movement of socio-economy seen in 2000s.

Autoscaling

 * Without Autoscaling: The fixed cost approach

 * With Autoscaling: The variable cost approach


Autoscaling is one of the remarkable advantages of using the public cloud because of its elasticity of the volume usage. This factor is also beneficial by means of the financial accounting.  However, Autoscaling is not that perfect as much as the salespersons from the public cloud providers advertise.  This short essay picks up the typical benefits and challenges of installing the public cloud especially because of its Autoscaling.

Autoscaling is a notable advantage of the public cloud which is usually emphasised in the introductory guideline of the public cloud advertisement. First of all, it allows its users to elastically adjust their quantity usage at each time period, instead of fixing the quality usage, depending on the fluctuant quantity demanded at each time period. This is useful to avoid both the dead-weight of the volume usage while the low access traffic and the volume shortage while the high access traffic.

Focusing on the accounting aspect, it can covert its usage cost to the variable operational cost instead of the capital or fixed-cost = liability. In many cases, it is often advantageous because it is likely to avoid paying the high tax levied onto the capital expenditure. By contrast, the cost covered for the public cloud is often accounted as the variable operational cost which is actually useful to reduce the total tax payment. Regardless of the total cost amount, in many administrative accounting cases, it provides individuals and their firms with the tax payment advantages.

At the same time, Autoscaling does not perfectly work as the textbooks and the introductory guideline of the public cloud explains. In reality, there is a limit of calling for extra instances at once because there is a certain maximum number of the server instances within a certain time period e.g., being able to call 5 instances per minute. There is a physical barrier of scaling the instances depending on each situation.

Furthermore, there is a case that the load balancer misjudges the health check of each connected server instance and the access control. This load balancer can accidentally call unwanted instances by falsely detecting as broken, deleted, or over-capacity or some errors of the monitoring tools and the metric/log information. In addition, there can also be a human error of typing the programmes of directing the traffic control or the security/monitoring setup. This may incur a considerable financial disadvantage of excess instances called by Autoscaling. 

All in all, the Autoscaling mechanism is still an attractive characteristic of using the public cloud to optimise the operational availability as well as the financial efficiency. Nevertheless, it must take an account of the dysfunctions of Autoscaling such as the latency of calling the instances and the extra possible costs caused by both machinery and human errors. On the top of what the salespersons and the textbooks indicate, the users had better refer to the actual experiences of its real application.

Crypto currencies based on the Block-chain technology e.g., BItcoin and the P2P networking are like Stirnerism in economy and finance!


 

The crypto-currencies are recognised as a double-edged blade for economy; it will stimulate economy with its innovative force whereas it also disturbs economy by challenging the already established stable system.  A famous astrologist has warned that these crypto-currencies will face a huge catastrophic shock in their market. 

It might be called an anarchist revolution in the world economic and financial systems. In particular, Stirnerism can be explained as the blockchain P2P network like Bitcoin. 

 

Frankly speaking, Stirnerist socio-political structure can be compared to the network of the blockchain like the one used in the cryptocurrencies such as Bitcoin.  This network system does not have any central server monitoring the entire system as a control tower.  

Instead, each individual computer calculates and verifies the interactions and actions among the community utilising this network system.  This is called the peer to peer (P2P) network where their application architecture is distributed among these individual computers.  These individual computers participate in their tasks and workloads as the peers.  The privilege and the equipment are equally distributed among these peers, and there is no authorities overriding their rules of activities. 

Like this P2P network, Stirnerian socioeconomic model requires the high competency level of all individuals participating in its socioeconomics. Like the P2P computer network system, all the participants must have a reasonably high specification level to cooperatively sustain the entire network structure. Each individual must be knowledgeable about the fair judgement and aware of their self-responsibility of contributing to their public goods and services (I.e., the free ride must be prevented with the best effort).  

 

The P2P network system of both the blockchain and Stirnerism face the identical characteristics of their challenges. This P2P system still need to tackle issues of managing of data serving and access authentication.  Establishing an centralised system is efficient to store and serve the collectively used data, services, and public goods because maintenance can be concentrated on the limited places.  By contrast, the P2P network requires all agents to share the same responsibility of maintaining, managing, and updating their quality of what required to prop up this whole entire system.  

 

In the past when the information technology is not developed as much as nowadays, there has no civilisation having succeeded in establishing such an individualist mutualist anarchist society like Stirnerism even for a short time period.  This is simply because it was unimaginable.  By contrast, Stirnerism has become imaginable to establish to the certain extend by comparing the socio-politics with the hard scientific technology since the introduction of the blockchain and its P2P network. 

There is an expectation that engineers and scientists develop the current P2P network system to transform it to the more efficient and manageable alternative. This innovation expected in the future will be beneficial to continue this currently ongoing revolution of decentralising the structure of both the information technologies and political science.

ETH plunging

I have once though that the depreciation of ETH has been caused by the entire crypto market situation. But, as I suspected the faster depreciation rate of ETH, I had a quick research on the endogenous cause of ETH depreciation. 

I found out that the ICO (Initial Coin Offering) demand has substantially dropped this year so that Ethereum's demand itself is now experiencing a massive fall out. 

By referring to a certain YouTuber's advice in his channel, I switched the majority of my ETHs to BTCs as there is still a growth expectation of the blockchain business and the crypto currency technology. 

I left only a few ETHs in case Ethereum may recover to the certain extend. However, I suspect the entire alternative (crypto) coins including ETH and the other emerging crypto currencies will keep facing a plunge at least for a few days.

The paradigm of the crypto-currency market changed 180 degree since about a half decade ago.

Very interesting for me! When I read a blog "The text book for being rich (Ironic name as the author says lol )" more than a half decade ago, I learned that Bitcoin could be a new alternative to Gold because of their similarities such as the supply limitation determining their price. However. the paradigm of the crypto-currency market changed 180 degree since about a half decade ago.

The supply of Bitcoin has the diminishing return because the supply is determined the overall CPU capability of all the computers participating in this blockchain network.  In another word, it cannot be simply printed of thin air like the fiat-currencies.  Therefore, these market participants used to think that, even though these crypto-currencies do not have their own precise physical forms, they were thought as though they had it. Therefore, many professionals including the author of this book suggested to treat the crypto-currency as an inflation hedge. 

Nevertheless, the paradigm has drastically changed since various other kinds of the crypto-currencies were introduced to the market so that Bitcoin has become far less scarce as it used to be since then.  Instead of the supply scarcity, the speculative demand has started to be far more influential on the crypto-currencies. 

The price inflation goes up when the capital market is heated up with extra confidence in investment more than saving. By contrast, the market falls into the deflation when the confidence goes down so that the market participants start preferring much safer assets than the volatile crypto-currencies.  Therefore, the crypto-currency value change is recently positively correlated. 

All in all, the correlation between the crypto-currencies have suddenly and drastically changed from negative to positive!

Explaining how expensive electricity is in Japan: Explained with the case of paper business

Especially after having turned nuclear power plants in Japan off since the last nuclear accident in Fukushina in March 2011, electricity in Japan is considerably expensive.  Even before then, it was expensive compared to the other countries because of its relatively heavier reliance on the thermal power plant fuelled with fossil fuels imported from abroad. 

It is difficult to explicitly display how expensive it is in Japan because there are so many variables to be compared with the significance of the electric power price influencing an economy there. So, one industrial case is introduced here to explain how significant Japanese electric price is as a significant variable cost incurred upon this industry.  This is paper manufacturing introduced here as an explicit example

Pulp is the base raw material of papers manufactured by a paper machine. Paper manufacturing needs cellulose fibres obtained most notably from woods. The more expensive finer alternative material can be cotton.

There are mainly two methods of producing pulp: chemically processed one and mechanically processed one.  The chemical pulping process uses chemicals and heat to convert woods into pulp meanwhile the mechanical pulping process grinds woods by mechanically defibrating wooden fibres into pulp.

The price of chemical components tends to influence the chemical pulp price whereas the usage volume of machinery consuming the high-volume electricity affects the mechanical pulp price. Supply of the chemical materials is often volatile and requires their characteristics of quality to match a particular level for pulping.

The mechanical pulping is not so prone to the conditioning as much as the chemical counterpart. Electricity is electricity whatever and whenever it is produced. The general specification of these pulping machines is not extensively dissimilar to each other in this world. 

In terms of the ordinary world situation, the former is more expensive than the latter, so the proportion of which pulp content to use determines the quality of papers as follows:

  • 上質 (directly translated as "high quality") : "Fine" paper/pulp: Chemical pulp 100%
  • 中質 : Medium quality": Mix of chemical pulp and mechanical pulp.

However, this is the way around in terms of Japanese paper & pulp business. The latter can be more expensive than the former despite their naming. This is because the latter requires to consume higher-volume electricity while their pulping processes. This factor indicates how expensive electricity generated in Japan even while taking the volatile chemical supply and price into consideration.

Having observed this paper business case, Japan is indeed urged to increase a far more efficient method of generating electricity overall. This current high electric bill price suppresses both business growth and individuals' utility by squeezing their household budget as an unavoidable cost for these activities. 

Nuclear power generation should be reactivated at least to repress the currently already intolerable cost inflation.  Perhaps, the research and development (R&D) inventing a new technology allowing Japan to fundamentally overcome from the high electricity generation cost is worthwhile to implement even its feasibility is questionable for the time being. 

The imaginable example is the nuclear fusion possibly enabling to supply the electricity satisfying the total demand of the entire Japan maybe even by replacing all the other existing electric power plants. It can be rather more productive to invest into efforts and time into increasing this feasibility to accomplish building this functional nuclear fusion power plant. 

 -

I consider that the nuclear power technology should be considered as a public good so I claim for the integration to a good government management or at least the civic-cooperative management looked after by several private individuals (The Classical Economics) rather than the current administration by one single private gigantic corporation detached from the fair market competition!

Well, this nuclear management industry has such a humongous economic of scale whose competition is nearly infeasible. So, I recommend either the full integration (the cohesive monopoly under a single public body such as government) or a cooperative management (classical economics example: democratically managed by several individuals living in this community)

JPY negative interest rate i.e. the inflation tax!


JPY holders are now experiencing the negative real interest rate steadily depreciating our real income, sigh. 

Interest rate r_US > r_Jp. ∴ Money Demand: MD_US > MD_JP
Furthermore, I detest the current Japanese interest rate policy. Usually, the nominal interest rate  is supposed to rise to offset the price inflation rate (ΔP) to keep the real interest rate (r - ΔP: what actually influences the money value held by the savers and the national debt investors) zero at lowest to make it fair and functional. 

The severe problem of Japan is that the current real interest rate for JPY is "negative (-)" which substantially discourages the money demand as well as reduces the real income value (income value depreciated by the price inflation). This is called the inflation tax because the price inflation works as though it were the tax imposed by government allowing the central bank to issue the excess money supply causing the price inflation depreciating the income. Because the inflation rate equally affects all individuals holding JPY, this is indeed a regressive tax (taxing proportionally more to the poorer but less to the rich)!!!!!

The reason why JPY interest rate has neither been raised nor seemed to rise soon is that the Bank of Japan (BoJ) is neglecting the interest rate rise despite this inflation. Actually, the Japanese government reject raising the interest rate because it is more likely to trigger the potential bankruptcy caused by their national debt interest payment overwhelming their budget. ......... thus, JPY holders are now literally experiencing the negative real interest rate steadily depreciating their real income.

Some very rich famous people must have predicted this world economic situation since ages ago. He's accumulated physical gold ingots in his own safe. The current world situation is really dodgy! ... under such a chaotic world situation, I'm thinking of you, my dear friends. Praying for safety of you and your family.
