MySQL system gained the reputation as the most efficient and speedy tool in managing databases long time ago. This system enables the creation and management of huge quantity of data which are supported by the multilevel and multipurpose charts. Oracle Company (the owner of MySQL) is making great strides in the development and improvement of new version of the system.


Several days ago Oracle introduced the new working MySQL 5.6 version of the system which is still in the development stage. No one dares to assume about the exact date of the final version release, but it’s definitely clear that Oracle will not delay the launch. The working version of MySQL 5.6 is replenished with the variety of new integrated options which make the system more effective and user-friendly.



Nowadays there are a lot of companies that employ MySQL as their core tool in creating and supporting of middle-size and large-size projects. Facebook, Flickr, and Twitter utilize the very system in their …

Introduction


Recently the AMD company hasn’t produced anything of such a high level but cutting edge Radeon R9 Fury X accelerator card as it paid more attention to the middle and low-budget segment. But finally after a long announcing Radeon RX Vega 64 and Radeon RX Vega 56 were officially presented and are being intensively bought.So what are their main characteristics?



Basic Features


No doubt it is a great step forward if to compare with the previous «Polaris 10» and «Fiji» graphic cards. The high-bandwidth cache controller (HBCC) is a serious improvement for using with large asset sizes, but gamers will also appreciate it.Vega RX 56 and 64 have 8 GB of VRAM.Newcomers have the Vega 10 processor in their base. It is a silicon with 64 huge Compute Unit blocks, general potential of 4096 streaming processors and speed memory HBM of the second generation. Vega 10 Processor is grounded on the most progressive version of Graphics Core Next architecture, that of …

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …
