LegacyWrapper 2.1 is out!

20.08.2017 | Programming | .NET C# Legacy Wrapper

Today, I released version 2.1 of my NuGet package LegacyWrapper. It comes with a major enhancement regarding the cross-architecture loading of DLLs: It is now possible to load 64bit DLLs from a 32bit process:

1using (var client = new WrapperClient(TestDllPath, TargetArchitecture.Amd64))
2{
3    result = (int)client.Invoke<TestStdCallDelegate>("TestStdCall", new object[] { input });
4}

As the second constructor parameter is optional and defaults to X86, the new release should be fully backwards compatible.

Improving page speed with a framework change

20.07.2017 | Programming | Framework Bootstrap Pagespeed

When I migrated my website to Jekyll a few months ago, I used a free template for my layout. Although it looked quite good, it came with a major tradeoff. It used Skel, a JavaScript framework for responsive websites. Skel loads arbitrary CSS stylesheets with JavaScript, based on the user’s screen resolution. This may sound convenient, but the page will load visibly slower, because the stylesheets will only load after all the JavaScript is loaded and executed. See an example of Skel in action in the following listing:

 1skel.init({
 2    reset: 'full',
 3    breakpoints: {
 4        global:   { range: '*', href: '/css/style.css', containers: 1400, grid: { gutters: 50 } },
 5        wide:     { range: '-1680', href: '/css/style-wide.css', containers: 1200, grid: { gutters: 40 } },
 6        normal:   { range: '-1280', href: '/css/style-normal.css', containers: 960, viewport: { scalable: false } },
 7        narrow:   { range: '-980', href: '/css/style-narrow.css', containers: '95%', grid: { gutters: 30 } },
 8        narrower: { range: '-840', href: '/css/style-narrower.css', grid: { collapse: 1 } },
 9        mobile:   { range: '-736', href: '/css/style-mobile.css', containers: '100%', grid: { gutters: 15, collapse: 2 } }
10    },
11    // ...
12});
