  2. 🚀 Behold the epic #saga of the #Redis #Array development: a four-month odyssey where our hero, armed with nothing but a keyboard and a penchant for "part-time" work, bravely battles the tyranny of specifications. How will he fare against the evil forces of #productivity and the lure of modern tech? 🤔 Stay tuned for the thrilling conclusion... if it ever arrives. ⏳😴

  3. Долгожданный оператор _Countof

    Одно из недооценённых событий уходящего года деревянной змеи - в проекте стандарта языка С появился оператор числа элементов. Как заметил один мудрый товарищ, Алексей Годин, даже полвека ещё не прошло, а наконец, дождались.

  4. Array.fill() Shares Same Reference?!

    This is a TRAP! Array.fill() with an object puts the SAME object in every slot. Change one, change ALL! Every element points to the same memory location. This silent mutation will destroy your data!

  5. The #Lazuli #Space #Observatory is a project of #Schmidt #Sciences,
    a philanthropic organization built by investor Wendy Schmidt and former Google CEO Eric Schmidt.

    “This is the first full-scale observatory that is privately funded in space,” says Stuart Feldman, an astronomer, computer scientist and president of Schmidt Sciences,
    who spoke to Scientific American before the announcement.

    “For 20 years, Eric and I have pursued philanthropy to seek new frontiers,”
    Wendy Schmidt said in a statement.

    “With the #Schmidt #Observatory #System
    [which includes Lazuli],
    we’re enabling multiple approaches to understanding the vast universe
    where we find ourselves stewards of a living planet.”

    As envisioned, the telescope will boast a three-meter mirror
    —larger than that of NASA’s iconic Hubble Space Telescope.

    Its three instruments
    —a planet-finding coronagraph,
    a high-resolution wide-field camera
    and a light-splitting spectrograph
    —will study the atmospheres of distant worlds, dissect the light from exploding stars and tackle mysteries such as the nature of dark energy, the enigmatic force that drives the universe’s accelerating expansion.

    Lazuli will be agile as well;
    it will be able to rapidly swivel to stare at things that go bump in the cosmic night.

    With a price tag rumored to be in the hundreds of millions of dollars, the telescope could launch before the decade is out.

    And if it is successful, the feat could signal a new way to achieve big things in the space sciences.

    “There’s a lot of good potential here,
    and it’s encouraging to see these new pathways opening for doing astrophysics,”
    says astronomer Heidi Hammel,
    vice president for science at the Association of Universities for Research in Astronomy.

    Lazuli is just one of several large projects comprising the Schmidt Observatory System

    —initiatives that Feldman characterizes as
    “risky but exciting.”

    The others are all ground-based and share a common design element in that they’re modular,
    using hundreds of small and relatively low-cost components to create much larger and more capable arrays.

    One, the
    #Deep #Synoptic #Array, will study the sky at radio wavelengths,
    while its counterpart,
    the #Argus #Array, will observe in visible light.

    A third smaller-but-scalable
    #Large #Fiber #Array #Spectroscopic #Telescope
    will gather spectra of cosmic targets such as exoplanets and supernovae.

    The goal, Feldman says, is for each of these projects to be doing science by 2029.

  9. Создаёте списки в C#? Ну тогда у вас могут быть проблемы

    Мы все привыкли писать new List<int> { 1, 2, 3, 4 } или new int[] { 1, 2, 3, 4} , чтобы инициализировать коллекции какими-то значениями. Синтаксически это выглядит похоже, но поведение отличается, и вам следует быть осторожными, если вы заботитесь о производительности.

  11. Preprint of the longest paper I ever contributed to: arxiv.org/abs/2505.08906 - it is a qualitative and quantitative comparison of various #functional #array languages, with a significant #gpgpu element.

  12. Безопасная работа с массивами? Нет, не слышали

    Рано или поздно любому разработчику на С-подобном языке приходит в голову идея использовать двумерный массив как одномерный. Причины для этого всегда разные, а вот результат чаще всего один. В этой небольшой заметке разберём эту сомнительную технику и какие проблемы она может привнести в вашу программу.

  13. Das EasyGate1541 jetzt auch für die 1541-II

    Das EasyGate1541 war bisher nur für die “alte” 1541 erhältlich. Die spätere 1541-II bekam von Commodore ein anderes Gate-Array, das noch mehr Funktionalitäten integriert hat. Es war an der Zeit, dass eine Alternative geschaffen wurde.

  14. Ersatz für das Gate-Array in der 1541

    Es gibt nur wenige Komponenten im Commodore 1541-Laufwerk, die gerne sterben. Das Gate Array, UC1 oder MOS 325572-01 ist eines davon. Und Ersatz ist nicht billig. Aber man kann sich auch einfach selber eines bauen.
