The JEDEC EIA370 transistor device numbers usually start with "2N", indicating a three-terminal device (dual-gate field-effect transistors are four-terminal devices, so begin with 3N), then a 2, 3 or 4-digit sequential number with no significance as to device properties (although early devices with low numbers tend to be germanium). For example, 2N3055 is a silicon npn power transistor, 2N1301 is a pnp germanium switching transistor. A letter suffix (such as "A") is sometimes used to indicate a newer variant, but rarely gain groupings.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the most common letter suffix?
Ah, so.. unanswerable

All YouTube users can upload videos up to 15 minutes each in duration. Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, which requires verifying the account, normally through a mobile phone. When YouTube was launched in 2005, it was possible to upload long videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films. The 10-minute limit was increased to 15 minutes in July 2010. If an up-to-date browser version is used, videos greater than 20 GB can be uploaded.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the time limit on video length first enacted on youtube?
Ah, so.. March 2006

On December 24, Yeltsin informed the Secretary-General of the United Nations that by agreement of the member states of the CIS Russian Federation would assume the membership of the Soviet Union in all UN organs (including permanent membership in the UN Security Council). Thus, Russia is considered to be an original member of the UN (since October 24, 1945) along with Ukraine (Ukrainian SSR) and Belarus (Byelorussian SSR). On December 25just hours after Gorbachev resigned as president of the Soviet Unionthe Russian SFSR was renamed the Russian Federation (Russia), reflecting that it was now a sovereign state with Yeltsin assuming the Presidency. The change was originally published on January 6, 1992 (Rossiyskaya Gazeta). According to law, during 1992, it was allowed to use the old name of the RSFSR for official business (forms, seals and stamps). The Russian Federation's Constitution (Fundamental Law) of 1978, though with the 19911992 Amendements, remained in effect until the 1993 Russian constitutional crisis.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what periodical was the new sovereign status of the Russian Federation last published?
Ah, so..
