jQuery - extension methods

By
De ceva vreme, Microsoft a inceput sa pompeze bani buni in jQuery. A fost integrat cu VS 2010( Visual Studio 2010), iar impreuna de MVC se integreaza perfect.
Am fost surprins sa descopar ca jQuery permite extension methods. Se pare ca Microsoft isi pune amprenta pe acesta, iar in acest caz eu cred ca intr-un mod placut.
Cum se declara:
 $.extend({
          [nume_metoda]: function([lista_parametri]) {
              [corp_metda]                 
          }
      });
Cum se apeleaza:
$.[nume_metoda]([lista_parametrii])

Ar fi interesant de folosit aceste metoda cand vrem sa declaram evenimente noi la anumite controale sau pentru a elimina helperele pe care le declaram uneori pentru tot felul de operatii.

Windows Docker Containers can make WIN32 API calls, use COM and ASP.NET WebForms

By
After the last post , I received two interesting questions related to Docker and Windows. People were interested if we do Win32 API calls from a Docker container and if there is support for COM. WIN32 Support To test calls to WIN32 API, let’s try to populate SYSTEM_INFO class. [StructLayout(LayoutKind.Sequential)] public struct SYSTEM_INFO { public uint dwOemId; public uint dwPageSize; public uint lpMinimumApplicationAddress; public uint lpMaximumApplicationAddress; public uint dwActiveProcessorMask; public uint dwNumberOfProcessors; public uint dwProcessorType; public uint dwAllocationGranularity; public uint dwProcessorLevel; public uint dwProcessorRevision; } ... [DllImport("kernel32")] static extern void GetSystemInfo(ref SYSTEM_INFO pSI); ... SYSTEM_INFO pSI = new SYSTEM_INFO(...

Navigating Cloud Strategy after Azure Central US Region Outage

By
 Looking back, July 19, 2024, was challenging for customers using Microsoft Azure or Windows machines. Two major outages affected customers using CrowdStrike Falcon or Microsoft Azure computation resources in the Central US. These two outages affected many people and put many businesses on pause for a few hours or even days. The overlap of these two issues was a nightmare for travellers. In addition to blue screens in the airport terminals, they could not get additional information from the airport website, airline personnel, or the support line because they were affected by the outage in the Central US region or the CrowdStrike outage.   But what happened in reality? A faulty CrowdStrike update affected Windows computers globally, from airports and healthcare to small businesses, affecting over 8.5m computers. Even if the Falson Sensor software defect was identified and a fix deployed shortly after, the recovery took longer. In parallel with CrowdStrike, Microsoft provi...
