Python script to pull hosted features with attachments into a local file geodatabase. See ReadMe below.
import os, urllib, urllib2, datetime, arcpy, json
## ============================================================================== ##
## function to update a field - basically converts longs to dates for date fields ##
## since json has dates as a long (milliseconds since unix epoch) and geodb wants ##
## a proper date, not a long.

def updateValue(row,field_to_update,value):
outputfield=next((f for f in fields if ==field_to_update),None) #find the output field

В компютърния свят, ядрото е фундаментална част от операционната система. То е част от софтуера, отговорен за предоставянето на сигурен достъп на програмите до хардуера на машината. Тъй като има много програми и достъпът до хардуера е ограничен, ядрото е също отговорно за решаването кога и колко дълго една програма ще бъде допусната да използва част от хардуера. Осигуряването на директен достъп до хардуера може също така да бъде много сложно, затова ядрата обикновено имплементират серия от хардуерни абстракции. Тези абстракции са начин, чрез който се скрива сложността, и се доставя ясен и непроменлив интерфейс към подлежащия хардуер, което улеснява живота на програмистта. Има четири вида ядра:

Монолитните ядра осигуряват богата и мощна абстракция от хардуера
Микро ядрата осигуряват малка серия от прости хардуерни абстракции и използват програми наречени драйвери, за да се сдобият с повече функционалност
Хибридните ядра са почти като микро ядрата, с изключение на това, че имат повече код в

1. What Is Kernel?

A kernel is a central component of an operating system. It acts as an interface between the user applications and the hardware. The sole aim of the kernel is to manage the communication between the software (user level applications) and the hardware (CPU, disk memory etc). The main tasks of the kernel are :

Process management
Device management
Memory management
Interrupt handling
I/O communication
