.NET - Nice to have

By

In C# la crearea unui obiect putem sa inițializam propietatiile acestuia prin următoarea sintaxa:

Engine engine=new Engine(…)
{
                Power = 101,
                Type = “ES12RW120TDI”
};
Am simtit uneori nevoie sa pot face acelasi lucre si cu un obiect deja creat. Exista locuri cand obiectul este initalizat de un factory sau deja exista, si trebuie sa schimbam valoarea unor proprietati. Mi-ar placea sa pot face urmatorul lucru:
Engine engine = InitEngine(…)
{
                Power = 101,
                Type = “ES12RW120TDI”
};
sau
use (engine)
{
                Power = 101,
                Type = “ES12RW120TDI”
};
In loc de
engine.Power = 101;
engine.Type = “ES12RW120TDI”;
Nu cred ca o sa vad vreodată acest feature si nici din punct de vedere a unui limbaj de programare sintaxa nu este tocmai corecta, dar ar fi nice to have, uneori ne-ar putea usura putin codul.

    Exact - in VB(.Net) exista dintotdeauna asa ceva, dar e mai mult un sintactic sugar care face codul sa arate ciudat..

    In 3 ani de zile de folosit VB am evitat with in general - in primul rand fiindca with in VB permitea cod arbitrar in interior, si se ajungea la carnatzi de 50 de linii in care nu mai stiai de ce obiect tine un property, de genul:
    With alertLabel
    If value = 0 Then
    .ForeColor = draw.Color.Red
    .Font = New draw.Font(.Font, draw.FontStyle.Bold Or draw.FontStyle.Italic)
    Else
    .Forecolor = draw.Color.Black
    .Font = New draw.Font(.Font, draw.FontStyle.Regular)
    End If
    End With

Why Database Modernization Matters for AI

By
  When companies transition to the cloud, they typically begin with applications and virtual machines, which is often the easier part of the process. The actual complexity arises later when databases are moved. To save time and effort, cloud adoption is more of a cloud migration in an IaaS manner, fulfilling current, but not future needs. Even organisations that are already in the cloud find that their databases, although “migrated,” are not genuinely modernised. This disparity becomes particularly evident when they begin to explore AI technologies. Understanding Modernisation Beyond Migration Database modernisation is distinct from merely relocating an outdated database to Azure. It's about making your data layer ready for future needs, like automation, real-time analytics, and AI capabilities. AI needs high throughput, which can be achieved using native DB cloud capabilities. When your database runs in a traditional setup (even hosted in the cloud), in that case, you will enc...

Cloud Myths: Migrating to the cloud is quick and easy (Pill 2 of 5 / Cloud Pills)

By
The idea that migration to the cloud is simple, straightforward and rapid is a wrong assumption. It’s a common misconception of business stakeholders that generates delays, budget overruns and technical dept. A migration requires laborious planning, technical expertise and a rigorous process.  Migrations, especially cloud migrations, are not one-size-fits-all journeys. One of the most critical steps is under evaluation, under budget and under consideration. The evaluation phase, where existing infrastructure, applications, database, network and the end-to-end estate are evaluated and mapped to a cloud strategy, is crucial to ensure the success of cloud migration. Additional factors such as security, compliance, and system dependencies increase the complexity of cloud migration.  A misconception regarding lift-and-shits is that they are fast and cheap. Moving applications to the cloud without changes does not provide the capability to optimise costs and performance, leading to ...

Cloud Myths: Cloud is Cheaper (Pill 1 of 5 / Cloud Pills)

By
Cloud Myths: Cloud is Cheaper (Pill 1 of 5 / Cloud Pills) The idea that moving to the cloud reduces the costs is a common misconception. The cloud infrastructure provides flexibility, scalability, and better CAPEX, but it does not guarantee lower costs without proper optimisation and management of the cloud services and infrastructure. Idle and unused resources, overprovisioning, oversize databases, and unnecessary data transfer can increase running costs. The regional pricing mode, multi-cloud complexity, and cost variety add extra complexity to the cost function. Cloud adoption without a cost governance strategy can result in unexpected expenses. Improper usage, combined with a pay-as-you-go model, can result in a nightmare for business stakeholders who cannot track and manage the monthly costs. Cloud-native services such as AI services, managed databases, and analytics platforms are powerful, provide out-of-the-shelve capabilities, and increase business agility and innovation. H...
