Krishna The three main goals of Software Testing are: Defect Detection: Find defects / bugs in the software during all stages of its development (earlier, the better). Defect Prevention: As a consequence of defect detection, help anticipate and prevent defects from occurring at later stages of development or from recurring in the future. User Satisfaction: Ensure customers / users … Read more
Debugging period (1947–1956) In 1947, the terms “bug” and “debugging” were coined. Grace Murray, a Harvard University scientist who worked with the Mark II computer, detected that a moth had got stuck in a relay causing it not to make contact. He detailed the incident in the work log, pasting the moth with tape as … Read more
China’s push to increase the adoption of electric vehicles (EVs) could curb the growth in oil demand by 70 per cent by 2030, a report from financial think tank Carbon Tracker has found. It reports that transport in emerging markets will account for more than 80 per cent of all expected growth in oil demand … Read more
HS2 Ltd has outlined its plans to incorporate robotic arms in its two tunnel-boring machines (TBMs), used to bore the 16km Chiltern Tunnel. The two 170m-long, 2,000-tonne TBMs – nicknamed Cecilia and Florence – were revealed in August. Beginning at a site near the M25, they will dig as deep as 90m below the Chilterns, … Read more
A UK study has revealed how micro-structured finlets on owl feathers enable silent flight – a discovery that could pave the way for reducing the noise of future aircraft. The study was conducted by researchers at City, University of London, led by Professor Christoph Bruecker, and was published in the Institute of Physics journal, Bioinspiration and Biomimetics. … Read more
The Welsh Government has revealed its draft strategy to reduce carbon emissions in the transport sector, placing private cars at the bottom of the list for investment. Transport currently makes up 17 per cent of Wales’ carbon emissions and the draft strategy, Llwybr Newydd – New Path, is set to shape the country’s transport system over … Read more
Greenhouse gas concentrations in the atmosphere have continued to increase during 2020 despite unprecedented falls in emissions driven by the coronavirus pandemic. While lockdowns around the world have cut emissions of many pollutants and greenhouse gases such as carbon dioxide, the drop experienced is no larger than normal annual fluctuations driven by the natural variability … Read more
NTRODUCTIONThis article provides a general introduction to the subject of penetrationtesting and provides the security professional with the background need-ed to understand this special area of security analysis. Penetration testingcan be a valuable tool for understanding and improving the security of acomputer or network. However, it can also be used to exploit systemweaknesses and attack … Read more
The majority of interesting attacks against web applications involve targeting the server-side application itself. Many of these attacks do of course impinge upon other users — for example, an SQL injection attack that steals other users’ data. But the essential methodology of the attacker is to interact with the server in unexpected ways in order … Read more
Introduction Bacula is an open source network backup solution that allows you create backups and perform data recovery of your computer systems.
