How to Report Bugs Effectively

How to Report Bugs Effectively
There are a number of ways in which non-programmers can contribute to software projects; documentation and testing are among the most frequently-requested services, but testing that results in useless bug reports accomplishes nothing but frustrating the programmer. Today, Simon Tatham shares what it's like to be on the receiving end of bug reports, and offers suggestions for how you can help resolve problems as quickly as possible. Introduction Anybody who has written software for public use will probably have received at least one bad bug report. Reports that say nothing ("It doesn't work!"); reports that make no sense; reports that don't give enough information; reports that give wrong information. There's a reason why technical support is seen as a horrible job to be in, and that reason is bad bug reports. In this essay I'll try to state clearly what makes a good bug report. In a nutshell, the aim of a bug report is to enable the programmer to see the program failing in front of him. Related:  TechnologyGeekiness

Nanotech tea bag creates safe drinking water instantly, for less than a penny @LittleDragon: Those devices you mentioned exist, and unless I'm mistaken, they work most of the time. However, they cost more thana penny each, and that's kind of the problem when dealing with Africa and other impoverished regions. @DrForbidden: But the machine that cleaned the water could be used by the entire village and was good for more then one use. Those pennies add up over time and people. The straws were also a multi-use item. I am aware of the money issue. All I am saying is that I have seen this clean water promise several times before and it never goes any where. @LittleDragon: I see your point. Hopefully, these teabags will be fully tested and available for sale by next year. @DrForbidden: I hope they are.

Controlling Plasma To Revolutionize Energy Generation And Storage April 17, 2013 [ Watch the Video: Plasma Device Could Revolutionize Energy Generation ] redOrbit Staff & Wire Reports – Your Universe Online Scientists at the University of Missouri have devised a new way to create and control plasma that could transform American energy generation and storage. Randy Curry, professor of electrical and computer engineering at the University of Missouri’s College of Engineering, and his team developed a device that launches a ring of plasma at distances of up to two feet. While most of us are familiar with three states of matter — liquid, gas and solid — there is also a fourth state known as plasma, which includes things such as fire and lightning. The secret to Curry’s success was developing a way to make plasma form its own self-magnetic field, which holds it together as it travels through the air. “Launching plasma in open air is the ‘Holy Grail’ in the field of physics,” said Curry.

Cyclic code In coding theory, a cyclic code is a block code, where the circular shifts of each codeword gives another word that belongs to the code. They are error-correcting codes that have algebraic properties that are convenient for efficient error detection and correction. If 00010111 is a valid codeword, applying a right circular shift gives the string 10001011. If the code is cyclic, then 10001011 is again a valid codeword. In general, applying a right circular shift moves the least significant bit (LSB) to the leftmost position, so that it becomes the most significant bit (MSB); the other positions are shifted by 1 to the right. Definition[edit] Let be a linear code over a finite field of block length n. is called a cyclic code if, for every codeword c=(c1,... obtained by a cyclic right shift of components is again a codeword. is cyclic precisely when it is invariant under all cyclic shifts. Cyclic Codes have some additional structural constraint on the codes. Algebraic structure[edit] . . Note that

Marion Hyper-Sub Check back often for the latest photos and news of the Hyper-Sub Fathom Prototype in action and on tour. Dive Testing Completed Successfully! - January 2008 The Hyper-Sub prototype has made history after two successful months of in-water testing! The Fathom performed magnificently in a thorough battery of tests of all vessel systems, and the team is proud to have a fully-functional submarine. Prototype testing highlights: 21 complete full-submersion dives. Dive Testing Continues - November 2007 Dive testing of the Fathom prototype is continuing throughout November. First Full Dive Test - Nov. 13, 2007 On November 13th, 2007 history was made with the first complete dive test of the Fathom prototype! Partial Submersion Testing, September 2007 The Fathom prototype returned to the waters of Kingsley Lake, Florida in September to continue the testing of the dive systems.

Quadratic residue code A quadratic residue code is a type of cyclic code. There is a quadratic residue code of length over the finite field whenever and are primes, is odd and is a quadratic residue modulo . where is the set of quadratic residues of in the set is a primitive th root of unity in some finite extension field of . is a quadratic residue of ensures that the coefficients of lie in . Replacing by another primitive -th root of unity either results in the same code or an equivalent code, according to whether or not An alternative construction avoids roots of unity. for a suitable . choose to ensure that while if is odd or according to whether is congruent to modulo . also generates a quadratic residue code; more precisely the ideal of generated by corresponds to the quadratic residue code. The minimum weight of a quadratic residue code of length is greater than ; this is the square root bound. Adding an overall parity-check digit to a quadratic residue code gives an extended quadratic residue code. (mod Hamming code over , the and the F.

Tecnologia | TRENDTECH Stranger Visions é uma daquelas exposições que nos assusta, nos faz pensar em questões de segurança, privacidade, e em como estamos evoluindo cientificamente e tecnologicamente. A artista Heather Dewey-Hagborg analisou o DNA de chicletes, bitucas de cigarro, fios de cabelo e outros objetos nas ruas de Nova Iorque, e, a partir disso, criou rostos impressos em 3D, com as características identificadas (gênero, cor do olho, cabelo, sardas, tom de pele, por exemplo). A qualidade do experimento ainda é mais artística do que qualquer coisa, mas imagine num futuro, onde a técnica seja mais precisa…seria o fim do retrato falado? Você poderia “ler” qualquer superfície e ver a cara de quem esteve por ali? Curtir isso: Curtir Carregando...

Kyocera Releases Solar Panel With Output of 238.1 W At Eco-Products 2010, Kyocera exhibited an industrial photovoltaic module with output of 238.1 W, which is among the highest in Japan. Now that Japanese power companies are building mega-solar projects, there is growing demand for solar power systems that produce at least 10 kW in the public and industrial sectors. The new high-output PV module enables providers to deliver higher output with fewer modules. "We previously sold PV modules with 54 cells, delivering an output of 208.4 W, as our main product. Now, we've developed this new, larger type of module with 60 cells." "By increasing the power output per cell, a 1 MW solar power system that previously required 4,800 conventional modules can be constructed using just 4,200 of the new modules. The 238.1 W modules can be used to achieve 10 kW with 42 modules, by arranging them in two rows of 21 or three rows of 14. Related Links :- YouTube- Press Release- Eco-Products 2010
