Question: Dell's reputation for poor customer service, since 2002, which was exacerbated as it moved call centres offshore and as its growth outstripped its technical support infrastructure, came under increasing scrutiny on the Web. The original Dell model was known for high customer satisfaction when PCs sold for thousands but by the 2000s, the company could not justify that level of service when computers in the same lineup sold for hundreds. Rollins responded by shifting Dick Hunter from head of manufacturing to head of customer service. Hunter, who noted that Dell's DNA of cost-cutting "got in the way," aimed to reduce call transfer times and have call center representatives resolve inquiries in one call. By 2006, Dell had spent $100 million in just a few months to improve on this, and rolled out DellConnect to answer customer inquiries more quickly. In July 2006, the company started its Direct2Dell blog, and then in February 2007, Michael Dell launched IdeaStorm.com, asking customers for advice including selling Linux computers and reducing the promotional "bloatware" on PCs. These initiatives did manage to cut the negative blog posts from 49% to 22%, as well as reduce the "Dell Hell" prominent on Internet search engines.
Which Dell employee was moved from head of manufacturing to head of customer service?
Dick Hunter

Several bronze-era states flourished in the area of Greater Armenia, including the Hittite Empire (at the height of its power), Mitanni (South-Western historical Armenia), and Hayasa-Azzi (1500–1200 BC). The Nairi people (12th to 9th centuries BC) and the Kingdom of Urartu (1000–600 BC) successively established their sovereignty over the Armenian Highland. Each of the aforementioned nations and tribes participated in the ethnogenesis of the Armenian people. A large cuneiform lapidary inscription found in Yerevan established that the modern capital of Armenia was founded in the summer of 782 BC by King Argishti I. Yerevan is the world's oldest city to have documented the exact date of its foundation.
When was the capital of Armenia established?
782 BC

Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.
What type of dielectric layer is used in electrolytic capacitors?

Answer: an oxide dielectric layer
