Lucifer - Let the pinhead sing

As with the episode before we hear music classic close or at the climax of the episodes. Last time it was Yahoo - or Yaz for the audience in the USA - performing Only You while in Let the pinhead sing Tom Ellis and Skye Townsend perform "I will survive" by Gloria Gaynor. According to some sources I found Tom Ellis loves to sing.




Computer generated alien intoning Gloria Gaynor's "I will survive"

Now while there is nothing wrong in my opinion to reproduce or just play some classic tunes it should not be overdone. I'd say if this happens in the next two episode The Last Heartbreak and Orange Is the New Maze. But if they continue this this with Orange Is the New Maze I might think the show ran out of ideas to fill the 45 minutes run time with content.

The usefulness of Daylight Savings

The usefulness of Daylight Savings

Twice a year it's Daylight Savings time. Well once you advanced the clocks by one hour, months later clocks are set back. Luckily in our automated world there are rarely any clocks left you have to set. NTP (network time protocol) or radio signals do this for us. But do we need Daylight Savings?

Different countries have adopted Daylight Savings in different years, handle them differently, some countries ignore them completely. The USA used Daylight Savings inconsistent between 1916 and 1966. But only in 1966 a federal law was established to regulate the proper use. During the oil crisis 1973 a year-round experiment was conducted to extend DST. 1976 the National Bureau of Standards found no significant energy savings or differences in traffic fatalities. Still DST was observed until today.

Benefits and drawbacks

Longer summer evenings

The daylight phase is at a later time. This is perceived by many people as an extension of the daylight time. Let's assume the time of sunrise at the beginning of summer is 4:30 am summer time instead of 3:30 pm standard time. Accordingly, the time of the sunset moves from about 9:00 pm normal time to 10:00 pm summer time. As the majority of people sleep at 3 and 4 o'clock in the morning, but not at 10 o'clock in the evening, and since today's society is based more on the time of day than the actual time of day, the wake-up phase of most people shifts more in the bright phase of the day. Thus, the leisure activities in the afternoon and evening are longer in daylight and pleasant outside temperatures possible; In contrast, daylight and temperature can be felt as disturbing at night.

Energy consumption

One of the official reasons for the introduction of summer time was already at the beginning of the 20th century the saving of energy. This argument has been controversial for most of the time. Because compared to other influences, the effect of the time shift on the energy consumption is negligible.

Although it was clear very early on that summer time could not have a decisive influence on energy consumption, this argument persisted in public awareness. However, in particular with the reintroduction of summer time in the Central European countries between 1976 and 1981, a possible energy saving - if at all - played only a minor role compared to the argument of a world wide standardization of times.

Summer time can have regionally adverse effects on energy consumption. In parts of Indiana, for example, it increased by about one percent after the 2006 summer season, which compares the electricity consumption of nearly 224,000 households. The originally pursued goal of energy saving could not be achieved. Rather, the energy balance was unfavorable, as "slight savings in the spring opposed an even greater power consumption in late summer and autumn". In particular, an increased need for heating in the early morning hours and a greater use of air conditioning in the longer afternoons and warm summer evenings increased overall energy consumption, for which the inhabitants of the examined parts of Indiana paid about 8.6 million US dollars per year more. The authors also calculated the cost of more pollution for society at $ 1.6 million to $ 5.3 million annually.

The data of this study, however, referred only to private households. Industrial plants and other economic sectors were not included. However, the authors suspect that most companies stick to normal working hours in daylight and are therefore less affected by the summer time change than private households.

The Federal Environmental Agency also found no positive energy-saving effects, since the saving in electricity for lighting is "overcompensated" by the additional consumption of heating energy due to the advance of the main heating time. The increasing use of energy-saving lamps would further increase this effect in the future.

Human nature

Advocates of summer time argue that it is beneficial for people to be able to spend more time in the evening in daylight hours, which increases their productivity. Opponents argue that adapting to the new daily rhythm takes at least several days, is harmful to health and reduces productivity during the changeover phase. Physiological studies suggest that some circadian fluctuating hormone levels, similar to those of stress hormones, may take up to four and a half months to fully adapt to new circumstances. Otherwise, "natural" direction when deferred to normal time, this adjustment would take only about two weeks. Whether these hormone level fluctuations already promote disease, but is not proven.

Technical effort

All watches have to be changed twice a year. More and more clocks are automatically set today via a radio signal, only few have to be changed manually, especially in private households. Computer clocks can also be set automatically via a function of the operating system. However, there are computer programs with real-time function, which do not use the operating system function for daylight saving time conversion and must be manually reconfigured. The same problem also exists with leap seconds.

Why we don't abandon Daylight Savings?

Suppose because in our interconnected world one country cannot just get rid of DST. Might cause too many problems negotiating around these obstacles. The United Kingdom BREXIT is not much of a help since countries from continental Europe are still her biggest trade partner. On the other hand if we tried hard enough to get rid of it everybody should benefit from it in the long term.
