블루투스(Bluetooth) 로고

블루투스(Bluetooth) 로고

개인 공간의 무선 장치를 연결하는 PAN(Personal Area Network)을 구성할 수 있도록 해주는 기반 기술인 블루투스(Bluetooth)는 잘 알려진 바와 같이 10세기경 덴마크와 노르웨이를 통일한 실존 인물인 하랄 블루투스(Harald Bluetooth, 덴마크 어: Harald Blåtand, 노르웨이 어: Harald Blåtann)라는 왕 이름에서 따온 것이다. 보통은 하랄 1세로 부른다. 노르웨이 최초의 통일 왕권을 이룬 왕이다. 블루베리를 좋아해 이가 파랗게 된 데서 이름이 연유했다는 설도 있고, 이가 빠진 자리에 파란 색 이를 해 넣어서 그렇다는 이야기도 있다. 또, 여기서 말하는 파란색은 실제 검은색을 말하는 것으로 다른 은유적인 뜻이 있다는 견해도 있다. 아무튼, 블루투스는 일종의 별명(닉네임)인 셈이다.

이렇게 이름을 얻은 블루투스는 요즘 이어폰, 헤드셋, 스피커, 마우스, 핸즈프리 등 다양한 분야에서 사용되고 있고, 이 기술이 적용된 장비에는 알파벳 B자를 응용한 듯한 로고가 그려져 있다. 그런데 이 로고는 사실 Harald의 "H"와 Bluetooth의 "B"를 따서 만든 것이다. H와 B를 고대 게르만족의 룬 문자(lune)로 표기한 것을 하나로 합친 것이다.

이 문자는 나중에 라틴 문자로 바뀌어 갔으나 노르웨이를 비롯한 스칸디나비아 일부에서는 꽤 오랫동안 사용된 것으로 알려져 있다.

세계 최초의 전자식 현금 자동 입출금기(ATM)

2008/09/21 14:23


An automated teller machine (ATM) is a computerized telecommunications device that provides the customers of a financial institution with access to financial transactions in a public space without the need for a human clerk or bank teller. On most modern ATMs, the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smartcard with a chip, that contains a unique card number and some security information, such as an expiration date or CVC (CVV). Security is provided by the customer entering a personal identification number (PIN). They are sometimes referred to as "ATM machines," a technically redundant term.

MITS Altair 8800(세계 최초의 상업용 조립식 개인용 컴퓨터)

2008/09/21 13:54


The MITS Altair 8800 was a microcomputer design from 1975, based on the Intel 8080 CPU and sold as a mail-order kit through advertisements in Popular Electronics, Radio-Electronics and other hobbyist magazines. The designers intended to sell only a few hundred to hobbyists, and were surprised when they sold thousands in the first month. Today the Altair is widely recognized as the spark that led to the personal computer revolution of the next few years: The computer bus designed for the Altair was to become a de facto standard in form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.

The MITS Altair 8800b was introduced in mid 1976 as the successor to the original Altair 8800 that appeared on the cover of Popular Electronics in January 1975. It had an improved front panel, larger power supply, an 18 slot mother board. The price was $840 for a kit and $1100 for an assembled unit. A typical hobbyist system with 16K of memory, a video display, a cassette tape data storage, and BASIC language software would be around $2000.

Bug (Software Bug)

2008/05/06 14:24


A software bug (or just "bug") (버그) is an error, flaw, mistake, "undocumented feature," failure, or fault in a computer program that prevents it from behaving as intended (e.g., producing an incorrect result). Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy. Reports detailing bugs in a program are commonly known as bug reports, fault reports, problem reports, trouble reports, change requests, and so forth.

The First "Computer Bug"
Moth found trapped between points at Relay # 70, Panel F, of the Mark II Aiken Relay Calculator while it was being tested at Harvard University, 9 September 1947. The operators affixed the moth to the computer log, with the entry: "First actual case of bug being found." They put out the word that they had "debugged" the machine, thus introducing the term "debugging a computer program." In 1988, the log, with the moth still taped by the entry, was in the Naval Surface Warfare Center Computer Museum at Dahlgren, Virginia.

Sustaining Technology vs. Sustainable Technology

2008/04/10 15:22


Sustaining Techology(존손성 기술, 지속성 기술) ↔ Disruptive Technology(와해성 기술)

Sustainable Technology(지속 가능 기술) < Sustainablity(지속 가능성)
Sustainability is a characteristic of a process or state that can be maintained at a certain level indefinitely. The term, in its environmental usage, refers to the potential longevity of vital human ecological support systems, such as the planet's climatic system, systems of agriculture, industry, forestry, and fisheries, and human communities in general and the various systems on which they depend in balance with the impacts of our unsustainable or sustainable design.

BusinessWeek Special Report: Sustainable Technology (March 17, 2008)

Charlotte's Cell Phone

[Charlotte's Cell Phone] Nokia and the University of Cambridge are using protein chains found in insulin to create a material that approaches the unmatched strength of spider web silk. Potentially, this substance could be melded with a resin-like substrate to build super-flexible shells for cell phones.

Like Pull Taffy, but Not Sticky

[Like Pull Taffy, but Not Sticky] Forget about armbands and belt holsters for your mobile device. The material being developed by Nokia and the University of Cambridge is so flexible that a phone made with it could, potentially, be wrapped around your wrist after you've finished talking.

One Contagious Battery

[One Contagious Battery] Massachusetts Institute of Technology researcher Angela Belcher is building a battery fueled by viruses. Harmless to humans, the viruses act as the carrot that lures molecules of gold and other elements together, catalyzing the chemical reactions that produce energy in a battery. Belcher's concept may allow for batteries that are tiny and flexible. One of her prototypes is not much bigger than a penny.

Harvesting a Laptop from Crops

[Harvesting a Laptop from Crops] Three electronics makers are testing a new bioresin from Cereplast (CERP) that's made in part from corn, wheat, and tapioca. Cereplast has begun producing the material, which can be used to make casings for devices such as laptops and mobile phones, at a plant that opened in January. The Seymour (Ind.) factory should pump out half a billion pounds of the resin when it's running at full throttle in early 2010.

Silky Sensors

[Silky Sensors] Rajesh Naik, biotechnology research lead at the U.S. Air Force Research Laboratory, is developing a thin film made from silkworm silk and enzymes that can act as an environmental sensor. Applied as a coating to everyday gear such as an MP3 player, the film could be used to analyze your sweat for signs you're coming down with the flu, or to check the air for contaminants you may be breathing.

The Building Blocks of Life—and Electronics

[The Building Blocks of Life—and Electronics] Paul Rothemund, senior research associate at California Institute of Technology, has laid the groundwork for using the DNA of microorganisms to build tiny computer chips. Rothemund is using strands of virus DNA to create intricate patterns that are just one-thousandth of the width of a human hair. The DNA patterns attract tiny nanowires into the same layout, causing them to self-assemble into intricate circuits.

A Bacterium Never Forgets

[A Bacterium Never Forgets] Using Rothemund's methods, IBM researchers are using bacterial DNA to create super-dense memory chips that would allow cell-phone users to record hours of video or store a terabyte of data, the equivalent of roughly 1,000 copies of Encyclopedia Britannica.

The Miraculous Properties of Castor Oil

[The Miraculous Properties of Castor Oil] Fujitsu has developed a new polymer that uses castor oil extracted from the seeds of castor beans. Plastics made with the polymer are super-flexible and can withstand repeated bending. Fujitsu eventually may use it to make small components for notebook PCs and mobile phones.

Salmon DNA Makes Better Lighting

[Salmon DNA Makes Better Lighting] Andrew Steckl, director of the Nanoelectronics Laboratory at the University of Cincinnati, is using salmon sperm DNA to create a new type of light-emitting diode (LED), the energy-efficient bulb used in everything from watches to Christmas-tree lights. By using DNA strands to isolate more luminophores—the molecules that generate light within LEDs—Steckl can produce LED bulbs that are 10 times brighter and last three to five times longer than current versions.
