A report from TheBestVPN notes that Android was the most vulnerable operating system (OS) in 2019. For the report, researchers crunched numbers from the National Vulnerability Database of the National Institute of Standards and Technology. Android topped the database with 414 vulnerabilities discovered in 2019.
The report notes that the number of vulnerabilities in Android has, in fact, gone down over the years. The smartphone OS faced 525 vulnerabilities back in 2018 and a whooping 843 vulnerabilities the year before.
In the end, it boils down to whether the smartphone is regularly receiving security updates. A recent report notes that more than a billion Android devices are at risk as they are running Android versions that no longer receive security updates.
While upgrading to Windows Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2) on Windows Small Business Server 2008, you will be present with the WSUS Configuration Wizard . You should not need to make changes to any section of this wizard except for the Choose Languages section. Making a change to any other section of the wizard may break the SBS console to WSUS integration.
By default only the default operating system language is selected. You must manually select any other language you wish to support. If you are running a non- English version of SBS you MUST ALWAYS select English in addition to your native language. You must include English due to the fact that some updates are only released in English.
Warning: Selecting a previously unused client language will download a significant amount of data and increase the size of the updates stored on disk. Do not select additional languages unless you have WSUS clients that require them.
You must be a member of the WSUS Administrators group on the WSUS server to perform this procedure. The SBS administration account is a member of this group by default.
For more information about this see the WSUS 3.0 SP2 Release Notes .
This information in this article is also documented in the following Knowledge Base document: After upgrading to WSUS 3.0 SP2 on Small Business Server 2008 only the local operating system l... .
The goal of SPR oil release was not achieved as oil prices increased marginally by US $1/barrel (b), after the announcement of SPR release. But when news of a new COVID-19 variant in South Africa broke on 26 November 2021, it did what the release of the SPR by the Biden administration could not, that is reduce oil prices and that too by a significant 10 percent. This implies that expectations of oil demand growth influenced by factors like the pandemic are more important in moving oil prices than expectations of supply corrections such as the oil release by the SPR. The apparent impotence of the SPR release raises questions over the costs and benefits of maintaining SPRs.
The capital cost for constructing the SPR facilities (phase I) was originally estimated to be INR 23.97 billion at September 2005 prices. The revised cost estimate for the three locations stands at INR 40.98 billion. Most of the capital cost was met with funds available with OIDB while Hindustan Petroleum Corporation Limited (HPCL) met the cost of 0.3 MT compartment at Visakhapatnam. Operation and maintenance cost of the strategic reserves is met by the Government of India. In the year 2019-20, ISPRL recorded a net loss of over INR 1 billion.
The dramatic increase in the price of oil in the late 1970s redefined the energy policies of industrialised nations from one that managed abundance to one that managed scarcity. Countries in Western Europe, barring France, and the United States reached an agreement to create the International Energy Agency (IEA) in 1974 to counter actions of the OPEC (Oil Producing and Exporting Countries). France and the US joined the IEA later. Though Henry Kissinger who coordinated the international response to the oil crisis had ambitious plans for the IEA, it eventually became a modest mechanism for managing scarcity through an oil sharing arrangement between member countries that required maintenance of strategic oil stocks to mitigate supply risk. All oil importing member countries of the IEA have an obligation to hold emergency oil stocks equivalent to at least 90 days of net oil imports. Industrialised countries represented by the IEA pushed for China and India to build and maintain strategic stocks of oil to address short term volume and price risk. Crude oil price increases generally result from actual or anticipated increase in demand or decrease in supply or both. The logic is that the release of SPR oil would potentially provide temporary relief from rising prices but more importantly make up for temporary supply losses that are behind the price rises.
Overall, the SPR is like an insurance policy against future oil supply or price shocks. The premium is the cost of maintaining the SPR. The issue is whether the premium is justified. The strategic importance of oil has reduced substantially partly because of abundant availability of oil resources and partly because of the negative perception of oil and other fossil fuels as sources of carbon emissions. Oil supply shocks have not only become rarer but also short lived. The benefit of SPR release in influencing price is probably overstated as the most recent SPR release illustrated. Maintenance of SPR is perhaps justified under current circumstances as oil continues to underpin almost all other energy sources including renewables (in manufacture and transport of renewable energy equipment). But in the future the value of the insurance premium on oil storage may have to be re-evaluated.
Jharkhand Chief Minister (CM) called on common people to generate solar power in their backyards and promised subsidy for setting up the plants for which a new scheme will be launched. He promised that the surplus power will be bought by the state government which will also help people generate additional income. Eighty-two projects worth INR2.75 billion (bn) (US$36.92 mn) were inaugurated, and the foundation stone for 18 schemes worth INR917.9 million (US$12.32 mn) was laid. Amongst the inaugurated projects, a grid substation at Itkhori and 108-km-long Chatra-Latehar transmission line will provide an uninterrupted power supply to large parts of Chatra district. Asserting that his government is promoting solar power generation, CM urged people to set up plants on barren lands and rooftops. As per the CM the government is preparing special plans for the development of backward districts such as Chatra, Garhwa, and Latehar.
