They were still accepted as payment in Greek influenced territories, even though these regions issued their own base coinage and some silver in other denominations, either called Greek Imperial or Roman provincial coins.

During the third century, the denarius was replaced by the double denarius, now usually known as the antoninianus or radiate, which was then itself replaced during the monetary reform of Diocletian which created denominations such as the argenteus (silver) and the follis (silvered bronze). After the reforms Roman coinage consisted mainly of the gold solidus and small bronze denominations. This trend continued to the end of the Empire in the West. See also Byzantine currency.

Unlike most modern coins, Roman coins had intrinsic value. While they contained precious metals, the value of a coin was higher than its precious metal content, so they were not bullion. Estimates of the value of the denarius range from 1.6 to 2.85 times its metal content, thought to equal the purchasing power of 10 modern British Pound Sterling (US$13) at the beginning of the Roman Empire to around 18 Pound Sterling (US$25) by its end (comparing bread, wine and meat prices) and, over the same period, around one to three days’ pay for a Legionnaire.

The majority of the written information about coins that survives is in the form of papyri preserved in Egypt¹s dry climate. The coinage system that existed in Egypt till the time of Diocletian¹s monetary reform was a closed system based upon the heavily debased tetradrachm. Although the value of these tetradrachmas can be reckoned as being equivalent in value to the denarius, their precious metal content was always much lower. Clearly, not all coins that circulated contained precious metals, as the value of these coins was too great to be convenient for everyday purchases. A dichotomy existed between the coins with an intrinsic value and those with only a token value. This is reflected in the infrequent and inadequate production of bronze coinage during the Republic, where from the time of Sulla till the time of Augustus no bronze coins were minted at all; even during the periods when bronze coins were produced, their workmanship was sometimes very crude and of low quality.

With the migration to commodity PC hardware, standard commercial “off-the-shelf” operating systems and programming environments can be used inside of ATMs. Typical platforms previously used in ATM development include RMX or OS/2. Today the vast majority of ATMs worldwide use a Microsoft OS, primarily Windows XP Professional or Windows XP Embedded. A small number of deployments may still be running older versions such as Windows NT, Windows CE or Windows 2000. Notably, Vista was not widely adopted in ATMs, and as at October 2009 no bank has announced a Windows 7 deployment. Java, Linux and Unix may also be used in these environments, but such deployments are rare.

Linux is also finding some reception in the ATM marketplace. An example of this is Banrisul, the largest bank in the south of Brazil, which has replaced the MS-DOS operating systems in its ATMs with Linux. Banco do Brasil is also migrating ATMs to Linux.
Security, as it relates to ATMs, has several dimensions. ATMs also provide a practical demonstration of a number of security systems and concepts operating together and how various security concerns are dealt with.

This stereotype (and the associated cognitive bias) may have some negative consequences and it can also damage a blonde person’s career prospects.

Blonde jokes have been criticized as sexist by several authors, as most blondes in these jokes are female, although male variations also exist. Research indicates that because of this, men find blonde jokes significantly more amusing than women say they do.

Many blonde jokes are variations on other stereotypical jokes. Blonde jokes nearly always take the format of the blond(e) placing himself or herself in an unusual situation, performing a silly act because he or she misconstrued the meaning of how an activity is supposed to play out, or making a comment that serves to highlight his or her supposed promiscuity, lack of intelligence, or cluelessness.
