We increase the randomness of that, and so[наверно] [почти]randomly  
random numbers are more tasty if they are slightly peppered
 
 
We will combine theory with practice-we will show that an improvement in the entropy of random sequences is possible, after which we look at the source codes that do this.
 
 
I really wanted to write about the fact that qualitative, that is, highly entropic, generation of random numbers is critically important in solving a huge number of problems, but this is probably superfluous. I hope everyone knows this.
 
 
In the pursuit of qualitative random numbers, people invent very ingenious adaptations (see, eg, ...

PowerShell and Group Policy Preferences, when the printers account for hundreds of

PowerShell and Group Policy Preferences, when the printers account for hundreds of  
 
Many copies are broken around managing network printers on user computers. Basically, administrators broke up into two camps: connecting log-scripts (bat /vbs) and managing via GPP. Both approaches have their advantages: scripts are processed more quickly, and GPP is more flexible and is used more often than users reboot computers. But when there are more than a hundred printers and they are scattered in several dozen offices and cities, there will be difficulties in both cases.
 
It is necessary not only to connect the correct set of printers to each user, taking into account his current location...

How did I generate the XML-statform for the customs and the union of the FCS with the tax

How did I generate the XML-statform for the customs and the union of the FCS with the taxIt all started when it came. Mysterious letter from Vladimir (?!) customs. Inside, there was a demand to provide statistical data on trade with Belarus and Kazakhstan for the whole of last year. And the reference to the decree of the sovereign, as it should be.
 

"For if you trade with the countries of the customs union, you should keep the answer. To whom, where, what sold out. All without a secret, write and especially the GTD number do not forget. The eye of the sovereign is not a drowsy eye. Systems electronic dogs iron for you, negligent, now follow the set, so do not be cunning. Put the ...

Parsing 0.5Tb xml for a few hours. Search of organizations by criteria in the register of subjects of SMEs of the Federal Tax Service

Parsing 0.5Tb xml for a few hours. Search of organizations by criteria in the register of subjects of SMEs of the Federal Tax ServiceBy the nature of the activity (automation of processes and the development of the architecture of information systems), one often has to deal with the need to write a script and get the result "here and now" for an unexpectedly "arrived" task in a situation where there is no possibility of promptly attracting external developers.
 
 
The review will be devoted to solving one such problem. At some point, there was a need to analyze, based on the open data of the "Single Register of Small and Medium Enterprises" of the Federal Tax Service (RNSS), the dynamics by months of the number of organizations ...

Mutual transformations of JSON, YAML, XML

JSON, YAML are now popular, and XML technologies are considered a relic of the past.
 
Mutual transformations of JSON, YAML, XML
 
Let's try to take advantage of dusty XPath, XQuery for data in JSON and YAML format. And we are discussing why all this "old" is applied to the modern and beautiful?
 
JsonPath repeats a subset of XPath, but only to the JSON format. And to write a declarative query without programming will not work - there is no analog XQuery. Alternatively, you could use any embedded database in jvm with its declarative language as a query, but this is a topic for a separate publication and the original data model in json, yaml ...
