today I want to write a few words about local blockchain environment for development.
In order to have everything on one machine for development you can consider following tools:
Chrome with metamask
For coding you can use Visual Studio Code ( there are ways of working with Visual Studio Proffesional or Enterprise but I didn't find way for 2017 editions. Only 2015 )
windows build tools ( installed via nodejs )
With list of those tools C# developers will fill themselves more or less in their plate and ready to go for development. At least I fealt :) more
today I want to write few words about global variables in Solidity. First of all I'd like to say that global means not only some global variable that you've declared in your code. Also it means part of memory whicy is automatically provided to your contracts.
In other words global means that those variables are always avaialable for any part.
The first is msg. Those three letter stand for word message and it is a structure that has fields sender, value, data, gas, signature.
For example in order to get sender, you can use following fragment of code:
address owner = msg.sender;
Next very interesting is amoung of ethers send. In order to get it following code can be … more
today I want to write a few words about data types in Solidity, language of programming for Ethereum and how they can be declared.
First of all there are simple types like byte, int, int256, uint128, bool etc. All of them are value types.
There are also bytes, string which are reference types.
Reference types has interesting features.
bytes a; is equal to byte a; in C#.
mapping is something like Dictionary in C#. For example you can make following dictionary Dictionary<string, int> prices; in Solidity like this:
mapping (string => int) prices;
In that case prices will a bit like a Dictionary in C#. For example you can write something like this:
prices["potatoes" … more
today I want to make post about solidity program.
Programs can start from pragma solidity line.
It looks like this:
pragma solidity 0.3.1;
pragma line says what is maximal version in which contract should be compiled.
often you can see line like this:
you can import some file which has extension ".sol" but file name should be without sol ending.
If to speak in analogies in C# or Java everything or almost everything is a class, but in Solidity everything is contract.
It can look like this:
Inside of your contract you can declare any kind of variables which are commonly named state variables.
Declaration goes … more
Today I want to write a few words about what is solidity, and why on Earth it was invented.
Before I'll do that few words about blockchain.
Blockchain consists of two main words: block and chain.
And special feature of blockchain is that it is made in a way, that each new part of it is made with taking into account previous blocks of information ( through hasing ). Another part is that everybody who is involved in blockchain has that information on theirs computers. In other words new additions somehow include information about previous pieces.
Then consider the following. Suppose government of some country want's to print more money. As usually they want to do it for … more
today I want to notice very important note about personal information which you can store if you develop blockchain that is used at EU zone.
Consider following scenario: you develop blockchain technology for your customers. For example you've bought from user some kind of service ( for example piece of source code ).
According to GDPR rules user can expect right to be forgotten by your service of storing source code. But you can't erase information about his source code for some reason ( other developers built based on his codebase,
or in case if source code that you've bought causing harm and you want to avoid/double check his source code, etc).
How to deal in that … more
today I want to write a few words about Income statment abbreviations which can be seen there.
First of all I'd like to say that Income statement often is named Profit and Loss account. In Acumatica it is named sometimes as PNL ....
COGS - cost of goods sold
SG&A expenses - Selling Generative and administrating. In other words operating expanses like salary, rent, electricity, etc.
Gross Margin = Total Sales - COGS
Gross Profit = Total Sales - COGS
Operating profit = revenues - operating expenses - depreciation - COGS
EBIT = Operating profit = Earnings before interest and taxes
EBITDA = Earnings before interest taxes, depreciation and amortization = gros margin - … more
today I want to write a short note about Depreciation and Amortization and whati is the difference between both.
So both of them reflect information about loosing value of some non current asset. If company bought something for one price, and with time that something looses it's value.
What the difference?
Depreciation is connected to tangible asset.
Amortization is connected to intangible asset.
For example loosing of value of laptop is characterized by depreciation.
Loosing of value of software is characterized by amortization. more
this post is intended for Acumatica developers which wonder about difference between AR and AP screen or as they named accounts payable and accounts receivable. If to speak simply both of them are intended for future benefits. The difference is just who is receiver of those benefits: your company ( accounts receivable ) or not your company ( accounts payable ).
Consider example: your company sells laptops. In case if HP gave you 10 latpops, then information about them will be written at your accounts payable. But for HP those laptops will be at accounts receivable. Let's say somebody made agreement with your company, that they will pay you in two months for 2 out of your 1 … more
today I want to make a post about by no means exhaustive but quite descriptive list of features in Acumatica.
Main features Acumatica
Advanced CRM - convert prospects to accounts with 1 click
Advanced accounting - multi-currency, consolidation ledgers
Advanced distribution - inventory, sales, purchasing
Employee portal (timesheets, expense reports)
Enterprise features - mid-sized business costs
Expense management … more
Today, I want to re-tell about Contract API Optimization. Materials get from conference of Acumatica and introduction by Joshua van Hoesen.
Three point of ineterst
Utilisation of ReturnBehavior
Avoid graph logic by creating Generic Inquiry for data retrieval
With the continued advancement of integrated software solutions, there has also been a need to address legacy business processes and how they may be implemented in a modern framework. These business processes tend to rely heavily on collecting large amounts of raw data from disparate sources and aggregating it together for further processing.
Some companies whose business process … more
now let's go for liability definition.
Liability in accountancy word definition is like this: present obligation of the firm to transfer economic benefits in the future to another party that arise from a past event or transaction.
Definition has following key parts:
past transaction event
From this standpoint bank loan is liability.
Potential lawsuite without estimated fine size can't be liability, but definetly should be mentioned in footnotes of balance sheet.
3 years warranty is also liability. For example warranty for the car. And if company can estimate their obligations on warranty then those kind of liabilities are … more
today I want to write few words about difference between something important in the company, that can be asset and close to asset but not be considered as asset from acocuntancy standpoint.
First of all let's start from definition. Asset has three key parts in its definition:
arises from transaction
Full definition of asset sounds like this: Asset is a resource owned or controlled by the firm that it is expected to generate future economic benefits and arises from a past event or transaction.
From this definition stnadpoint piece of equipment which is worth 1M $ is an asset because
owned by company
will generate profit
resulted … more

Extreme Programming Methodology
Joint Application Development
How many of those you know/tried/practiced? more
There are two main standartizers of Accountancy:
IFRS stands for Inernational Financial Reporting Principles. IFRS is set in London by International Accounting Standards Board IASB.
US GAAP - United States Generally Accepted Accounting Principles. US GAAP is set by Financial Accounting Standards Board.
in order to become better Acumatica developer I've decided to take course on Accounting: Principles of Financial Accounting.
Here I'll share some ideas that become new to me.
So, I want to speak about Prospectus.
Securities and Exchanges commision requires that any kind of company that borrows money from potential investors provide to them document which has following information:
Other information that will help investors to make informed decision
So, next time when I'll hear prospectus it will mean for me some kind of document which will say something like … more
