    Is OOP dead?

    OOP has been eliminated from the introductory CS curriculum at Carnegie-Mellon-University (CMU) in favor of an introductory course to functional programming. They say that OOP "is eliminated entirely from the introductory curriculum, because it is both anti-modular and anti-parallel by its very nature, and hence unsuitable for a modern CS curriculum". And this is but one of the many criticisms of OOP.

    Reshared text:
    I flipped the developer switch on my $249 Chromebook, downloaded crouton, typed in a few commands, waited several minutes, and now I'm running a full version of Ubuntu alongside stock Chrome OS.

    My Chromebook is no longer just a content-consumption device, as I now have access to the full suite of GNU/Linux programs that I'm already used to using. I immediately installed Emacs, GCC, gEDA, and a cross-compiler so I can use it to design circuit boards and program microcontrollers.

    There is no dual booting involved, nor am I paying the performance/memory hit of running an entire OS in a virtual machine (it shares its kernel with Chrome OS). The Chromebook still cold boots in just a few seconds, wakes from sleep instantly, and receives its updates like normal. Chrome OS handles the network, power management, and other hardware like a champ, the only difference being that if I want to do something more than just surf the web, I can hold down a few keys, and instantly switch between Chrome OS and Ubuntu.

    I can't believe that I ever considered buying an expensive MacBook Air and installing GNU/Linux on it, when for just the price of the AppleCare Protection Plan alone, I was able to buy an entire (brand new) laptop that got me the same end result with minimal effort.

    Interesting article: On Hacking MicroSD Cards

    Some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself.

    On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks, where the card seems to be behaving one way, but in fact it does something else.

    On the light side, it also enables the possibility for hardware enthusiasts to gain access to a very cheap and ubiquitous source of microcontrollers.

    The Window Socket offers a neat way to harness solar energy and use it as a plug socket. So far we have seen solutions that act as a solar battery backup, but none as a direct plug-in. Simple in design, the plug just attaches to any window and does its job intuitively.

    Interesting list

    1. Hydrogen is a major component in the fuel cells of some vehicles, such as the 2007 Mazda Premacy Hydrogen RE Hybrid.

    2. Helium serves as a cooling agent for such common products as the Bulldozer CPU, and it helped to cool a CPU that broke the overclocking world record.

    3. Lithium is found in batteries for small electronics. For instance, lithium-based batteries are found inside the Apple iPhone 5. 

    4. Beryllium is used in the manufacture of high-frequency speaker drivers. Occasionally products will be marketed as containing beryllium, yet they may not. You'll most likely find beryllium in high-end home applications, such as the Pioneer S-4EX speaker system.

    5. Boron, like silicon or germanium, is a common doping agent in semiconductors. In English, that means small traces of boron are added to other elements to alter their properties. This is a crucial step in the production of CPUs such as the Intel Core-i5 quad-core desktop processor. 

    6. Carbon: PC makers frequently use carbon fiber in laptop chassis designs because it is lightweight, and improved manufacturing techniques are reducing the cost and time necessary to make this material. The Lenovo ThinkPad X1 Carbon laptop has a carbon-fiber shell.

    7. Nitrogen acts as a cooling agent in some extreme cases, particularly in overclocking a PC—the process of pushing your computer components harder and faster than the manufacturer designed them to go. If you’re planning to do some extreme overclocking, you’re going to need to buy special equipment for using liquid nitrogen with your PC.

    8. Oxygen is used in the production of pretty much everything, but its liquid form is used to make polyethylene terephthalate, or PET. Many screen protectors for touchscreen smartphones and tablets, like BodyGuardz Classic screen protectors, are made of PET.

    9. Fluorine reacts with glass and acts as an etching chemical, removing unwanted film buildup in glass production. It’s used in the production of LCD desktop monitors and TVs, including the line of Kyocera Display TFT monitors.

    10. Neon: Back in the 1920s, the first commercially available television sets contained neon in their TV tubes. Today, neon is found in plasma TVs such as the Panasonic Smart Viera Plasma HDTV, Class ST50.

    11. Sodium: Alternative energy production methods use sodium-sulfur batteries. The town of Presidio, Texas, uses a large sodium-sulfur battery as the emergency backup energy source.

    12. Magnesium is a strong metal and commonly serves as a construction material. The new Microsoft Surface RT contains magnesium.

    13. Aluminum is a strong, light metal, and is optimal as a construction material. Apple's MacBook Pro line features an aluminum unibody design, as does the Samsung Series 7 notebook.

    14. Silicon: CPU makers construct their chips using silicon as a “scaffolding” of sorts, and they dope certain other parts of silicon with small quantities of other elements to make it more susceptible to conducting electricity. Intel offers a cool infographic that shows how a CPU is made; it all starts with sand, which has a high percentage of silicon dioxide.

    15. Phosphorus is commonly used in fluorescent light bulbs.

    16. Sulfur: As listed under sodium (11), sodium-sulfur (NaS) batteries play a role in alternative energy production methods. Tokyo's power plants used NaS batteries to generate additional power during the peak summer energy demands in 2010.

    17. Chlorine: According to the Dow Chemical Company, chlorine technology is used in the manufacturing of memory cards.

    18. Argon can glow either bright blue or bright green, so argon ion lasers are a common feature in laser light shows.

    19. Potassium: Potassium bromide (potassium combined with bromine) acts as a black-and-white film-developing agent in film photography. It improves the differentiation between exposed and unexposed crystals of silver halide, and thus reduces fog. You can purchase potassium bromide as developer formula.

    20. Calcium: Calcium fluoride lenses reduce light dispersion in photography, in a method that was introduced in the 1960s. The Canon EF 17-40mm f/4L USM Ultra-Wide Zoom lens is calcium fluoride-based.

    21. Scandium is used in the bulbs in metal halide lamps, which produce a white light source with a high color rendering index that resembles natural sunlight. These lights are often appropriate for the taping of television shows.

    22. Titanium, a strong metal, serves as a tech construction material. The old Apple PowerBook G4 had a titanium edition made of this metal.

    23. Vanadium: Although rechargeable vanadium redox batteries haven’t caught on commercially yet, they are acclaimed as being instrumental in renewable-energy plans.

    24. Chromium is a transition metal and has a variety of industrial uses due to its toughness and its high resistance to heat and corrosion. Vinyl-record lovers should note that RCA Victor record player needles are based on chromium.

    25. Manganese is essential to the alkaline battery. Such batteries work due to a reaction between zinc and manganese dioxide. Any common alkaline battery—such as those of the Duracell and Energizer brands—has manganese.

    26. Iron: The strength and low cost of iron make it perfect for engineering applications, and iron compounds serve as an etchant for copper in the manufacture of printed circuit boards (such as the Sunstone PCB collection).

    27. Cobalt is found in lithium ion batteries (such as Panasonic rechargable lithium ion batteries), in the form of lithium cobalt oxide.

    28. Nickel is present in batteries such as the nickel-metal hydride battery used in hybrid cars. Both the Honda Civic Hybrid and the Ford Escape Hybrid use these batteries.

    29. Copper is found in almost all electronics, as it is superior to comparative elements—like aluminum—in electricity and heat transfer. For example, take any stick of RAM and look at where it connects to the computer; all of those connections are made of copper.

    30. Zinc is used in different types of batteries, such as the zinc-carbon battery (in which zinc is the case for the battery), the nickel-zinc battery (often found in cordless phones or digital cameras), and the zinc-air battery (commonly found in hearing aids, as well as in electrical vehicles).

    31. Gallium: A gallium compound—gallium nitrate—is used to make the laser diodes on Blu-ray players such as the Samsung BD-E6500 3D Blu-ray player.

    32. Germanium acts as a doping agent with silicon to increase its speed in CPU production. IBM and Georgia Tech push the boundaries of silicon-germanium CPUs by testing them at extreme temperatures.

    33. Arsenic: Though not directly related to any tech product because of its toxicity, arsenic is commonly used in bronzing and pyrotechnics.

    34. Selenium: The copper indium gallium selenide compound is used in the production of some solar cells, specifically the thin-film category. The Brunton Solaris 52 CIGS Foldable Solar Panel uses selenium (the "CIGS" in its name stands for copper indium gallium selenide).

    35. Bromine compounds are used to make the light-sensitive component of photographic emulsion—without bromine compounds, photographs would not capture sufficient light. One such product is Kentmere bromide photo paper.

    36. Krypton gas is whitish in color, so krypton-based light bulbs are useful in photography as a brilliant white light source. Krypton is often used in high-speed photography.

    37. Rubidium: Although this item is more for hobbyists, rubidium is used in atomic clocks as a reference. You can buy a Rubidium atomic clock on eBay.

    38. Strontium compounds contribute to the glass of CRT TVs and monitors, to prevent X-rays from coming through. The old Gateway VX720 17-inch Flat-CRT monitor featured a strontium compound.

    39. Yttrium helps CRT televisions produce a red color. When used in a compound, it collects energy and passes it to the phosphor.

    40. Zirconium is extremely resistant to heat, so it’s ideal for space vehicles and aircraft. Jet-engine blades are manufactured with zirconium.

    41. Niobium: Lithium niobate is used in mobile phone production, incorporated into surface acoustic wave filters that convert acoustic waves into electrical signals and make smartphone touchscreens work. SAW filters also provide cell signal enhancement, and are used to produce the Apple iPad 2.

    42. Molybdenum is mainly used in steel production—it has the ability to withstand extremely high temperatures without changing shape. It is a component of armor, aircraft parts, industrial motors, filaments, and electrical contacts.

    43. Technetium: Despite its name, technetium is used mainly in the medical industry. It serves as a medical tracer that doctors can detect in the human body with a gamma camera.

    44. Ruthenium, when added to compounds, is used to make dye-sensitive solar cells, but those aren't commercially available.

    45. Rhodium: Like platinum (78), rhodium is used in catalytic converters for cars, but rhodium is specifically suited for diesel-powered vehicles.

    46. Palladium is used to make multilayer ceramic capacitors. These take the form of squares or rectangles mounted on the surface of a printed circuit board; you'll see them on most computer motherboards.

    47. Silver is used to make high-quality connections, such as RF connections and coaxial cables. Plenty of cables have silver in their connectors.

    48. Cadmium, used in the production of cadmium telluride photovoltaics, offers a cheap and efficient method of manufacturing solar panels. Though it isn't widely available for commercial use, you can find some places to buy the panels online, including eBay (the term “CdTe” refers to the cadmium telluride compound).

    49. Indium is used in the production of indium gallium zinc oxide (IGZO) displays, notably produced by Sharp.

    50. Tin is widely used in solder, generally alongside lead, with an average ratio of 60 to 40 (lead to tin). Solder is found in just about every single electronic device.

    51. Antimony: About 60 percent of antimony goes toward making flameproof compounds for children's clothing, toys, and seat covers. A smaller use of antimony is as a fining agent to remove microscopic bubbles in glass, mostly for TV screens.

    52. Tellurium: When paired with cadmium (48), tellurium creates cadmium telluride photovoltaics, and offers a cheap and efficient method of manufacturing solar panels.

    53. Iodine: Potassium iodide and silver iodide, two different iodine compounds, are used in film photography. A layer of silver iodide sits directly on the film or photo paper and reacts with white light to complete the image.

    54. Xenon: The individual cells in a plasma display—such as the Panasonic VT50—employ a mixture of xenon and neon that electrodes convert into a plasma. Xenon arc lamps are present in IMAX film projection systems.

    55. Cesium is used in atomic clocks, which manage time in applications such as cell phone networks. Atomic clocks also aid in the timing of the information flow of the Internet. You can buy a Cesium atomic clock online, though it will cost quite a bit since it is more of a niche item.

    56. Barium, typically as barium nitrate, is added to fireworks to turn them green.

    57. Lanthanum helps produce nickel-metal hydride batteries, which most hybrid cars use. A typical hybrid battery for a Toyota Prius requires 22 to 33 pounds of lanthanum.

    58. Cerium is an essential component of phosphors present in TV screens.

    59. Praseodymium helps to form the core of carbon arc lights, which are used for studio lighting and projector lights in theaters.

    60. Neodymium is a direct component of neodymium magnets, the strongest permanent magnets known. They are found in hard drives, such as this Western Digital internal drive. 

    61. Promethium: Most promethium is used only for research purposes, but it could be employed in atomic batteries.

    62. Samarium: You can find samarium cobalt magnets in small motors, headphones, high-end magnetic pickups for guitars (such as Samarium cobalt noiseless guitar pickups) and related musical instruments.

    63. Europium is present in LCD monitors (such as this model from Acer) as a component of phosphors. It helps to make colors, specifically red, vibrant.

    64. Gadolinium acts as the recording medium for CDs.

    65. Terbium is another component of LCD-monitor phosphors. It helps to increase the vibrancy of colors, especially green.

    66. Dysprosium: Because dysprosium and its compounds are highly susceptible to magnetization, they are employed in various data storage products, such as hard disk drives (including the Seagate Barracuda desktop hard drive).

    67. Holmium has few commercial applications, but it is used to make parts for magnets that produce intense magnetic fields, such as the magnetic flux concentrator.

    68. Erbium is pinkish in color, and commonly serves to color glass for photo filters (such as in the Lomography Colorsplash 35mm camera).

    69. Thulium is rare and expensive, so it's found in few commercial products. However, it has acted as a power source for portable X-ray machines and in parts of microwave equipment.

    70. Ytterbium isn’t widely used commercially, but this silvery metal is found in laser technology, specifically in wavelength-tunable solid-state lasers. These lasers cut silicon wafers for solar panels.

    71. Lutetium: A tiny amount of this rare element is added to gadolinium gallium garnet (a synthetic crystalline material) to alter its electrical properties. In the early days of computers, the result contributed to a method of recording data in bubble-like magnetic regions on the surface of a chip. For a look at this vintage computing method, read up on Intel 7110-1 bubble memory.

    72. Hafnium is part of a compound that is employed as a gate insulator in some processors, such as Intel’s 45-nanometer processors. The Xbox 360 and PlayStation 3 Slim Edition feature different 45nm processors.


    73. Tantalum is present in capacitors for electronics, such as motherboards. Most motherboards, like the MSI Z68A-G43 (G3), feature tantalum capacitors.

    74. Tungsten is a component of cathode ray tubes, or CRTs, which are found in monitors (like this old Dell CRT) and old-school TVs.

    75. Rhenium: About 70 percent of the worldwide rhenium production goes to making jet-engine parts, due to its high melting point. Turbine blades for jet engines such as the Airbus A380 are made from rhenium.

    76. Osmium alloys are really hard and don’t bend easily, so they contribute to the production of electrical contacts, which are the points in a circuit that allow a current to pass from one conductor to another. Every electronic device uses electrical contacts—that’s how electrical currents flow.

    77. Iridium alloys are resistant to arc erosion, so they're used to make electrical contacts in spark plugs. Select Toyota models use iridium spark plugs.

    78. Platinum: Apart from being crafted into fine jewelry, platinum is used in vehicle-emissions control systems, specifically in catalytic converters. Platinum is often the catalyst that converts the toxic by-products of combustion in the exhaust to a less toxic substance.

    79. Gold serves as a connector in electronics, usually as a plating or covering, because of its high conductivity to electricity. A common use of gold plating is in headphone connections.

    80. Mercury: Owing to its acoustic properties, mercury acted as the propagation medium in delay-line memory devices used in early digital computers of the mid-20th century.

    81. Thallium is used in photo-resistors, which appear in everything from streetlights to alarm clocks. Most things that react to light, especially in a basic sense, use photo-resistors.

    82. Lead is employed in the making of solder, although it’s being phased out in some countries to reduce toxic materials in waste. Solder is found in just about every single electronic device.

    83. Bismuth: The compound bismuth telluride is a semiconductor and works as an effective CPU coolant (for example, see this 9cm Water Evaporator/Cooler for CPU cooling).

    84. Polonium: Polonium serves as an atomic heat source, because it spontaneously heats up to about 932 degrees Fahrenheit. In the 1970s, scientists working for the Soviet Union's Lunokhod used polonium to keep the internal components of moon rovers, specifically the Lunokhod 2 Moon Rover, warm during lunar nights.

    85. Astatine is highly radioactive and is available only in tiny quantities, typically because it has a short half-life. It was named the rarest element on earth by the Guinness Book of World Records.

    86. Radon is extremely radioactive and is considered a highly dangerous material, so it isn't found or used in the production of common consumer items. However, it is sometimes employed to treat cancer, in the form of radiotherapy-implantable seeds.

    Software engineering has long considered itself one of the hard sciences, but the rigorous examination of cause and effect that characterizes science has been much less common in this field than in supposedly soft disciplines like marketing, which use rigorous, quantitative and analytic approaches. Some researchers believe software engineering is now at a turning point comparable to the dawn of evidence-based medicine, when the health-care community began examining its practices and sorting out which interventions actually worked and which were just-so stories.

    Gosh, I missed that offer :-)

    More seriously, this ad dated 1981 reflects several software myths that some are still believing:

    1) That the total amount of software that could be produced is more or less bounded. 

    2) That natural language is the ultimate frontier in the specification of software systems.

    3) That software that generates software is a new idea. Since the beginning computers have got devices like card punchers when there was no magnetic tapes to be able to produce card decks from other card decks. This was used to produce for example self-loading bootstrapping binary programs from  symbolic assembly languages. Later, in the 70's compiling techniques were much improved. More recently code generation from abstract models became quite popular in Model Driven Engineering.

    Plus ça change, plus c'est la même chose ;-)
