One of the most common performance issues I’ve seen in Laravel is using Eloquent methods and relationships from Blade, creating unnecessary extra loops and queries. In this article, I will show different scenarios and how to handle them effectively. Scenario 1. Loading belongsTo() Relationship: don’t forget Eager Loading Probably, the most typical case – you’re looping with @foreach through the records, and in some column you need to show its parent record with some field. @foreach ($sessions as $session) {{ $session->created_at }} {{ $session->user->name }} @endforeach And, of course, session belongs to user, in app/Session.php : public function user() { return $this->belongsTo(User::class); } Now, the code may look harmless and correct, but depending on the controller code, we may have a huge performance issue here. Wrong way in Controller: public function index() { $sessions = Session::all(); return view(‘sessions.index’, compact(‘sessions’); } Correct way: public function index() { $sessions = Session::with(‘user’)->get(); return view(‘sessions.index’, compact(‘sessions’); } Notice the difference? We’re loading the relationship with the main Eloquent query, it’s called Eager Loading . If we don’t do that, in our Blade foreach loop will call one SQL query for every session, asking for its user directly from the database every time. So if you have a table with 100 sessions, then you would have 101 query – 1 for session list, and another 100 for related users. So, don’t forget Eager Loading. Scenario 2. Loading hasMany() Relationship Another typical scenario is that you need to list all child entries in the loop of parent records. @foreach ($posts as $post) {{ $post->title }} @foreach ($post->tags as $tag) {{ $tag->name }} @endforeach @endforeach Guess...
by Shishir Dubey November 1, 2018 This article is going to be all about a comparatively common term which many entrepreneurs neglect when it comes to mobile app development – MVP App Design and MVP App Development for their mobile app based business. The competition is fierce when it comes to mobile app development. You think of an idea and boom! Someone already has built a similar product somewhere or the other. It’s quite a lot challenging to come up with a mobile app idea which is 100% unique. But it’s even more challenging to figure out – Everyone is competing with the other to launch their product in the market first. Gaining the competitive edge in the market has become a NORM more than an EXCEPTION. If your mobile app doesn’t have the competitive edge, surviving in the market is going to be difficult. A mobile app user always has three expectations from any mobile app he/she uses – Smooth app navigational experience. To-the point solution for the requisite problem in hand. and A well-maintained feedback and customer support channel. If your app has all the above, there is nothing that can stop it from becoming a hit. If not, It’s time to re-work. The reason I am discussing this is because – At ChromeInfotech, we have developed a plethora of apps for various industry segments. Majority of the apps went on to become a market hit. Each of them were well funded (above a million-dollar mark) and were a customer-viable product. Some of them did not perform up to the mark despite having backing of – Adequate...

GCHQ director Jeremy Fleming, boss of the Government’s eavesdropping station, told experts that action was needed if western democracies were to retain powers to decide the future of crucial tech systems. Speaking at the CyberUK 2021 virtual conference, he said: “Without action, it is increasingly apparent that the key technologies on which we rely for prosperity and security won’t be shaped and controlled by the West. “We can see significant technological leadership is moving East. “It’s causing a conflict of interests, of values, where prosperity and security are at stake. “It follows that cyber security is an increasingly strategic issue that needs a whole of nation approach if we are to continue to reap the benefits of technology. “These are really big themes and they have big stakes. “There is no doubt we are facing a moment of reckoning; I am optimistic about our response – after all, the UK has considerable soft and hard power. We are already a leading cyber power. “We have a history of technological innovation – from the early proto computers to the World Wide Web, British ingenuity continues to shape the world. “But it is clear that to face up to this moment of reckoning we need...
**Update – New ASP.NET 5 video coming soon, follow me on Twitter to keep an eye on announcements ** Most of my enterprise career was web based. In around 1997 my first major web project was to create the sign-up 3.5″ floppy disks that were distributed with a good amount of Bell Atlantic phone books. This used all sorts of c-based cgi, Python scripts, and a mish mosh of tech. Things were so very very different then. We were actually the very first all Windows NT Internet Service Provider in the country. Good times but was web tech surely in its infancy. When ASP (Active Server Pages) first came out, it was amazing – it so we thought at the time as we spaghetti coded away our scripts. Fast forward nearly 20 years to ASP.NET 5. A technology that shares only letters with its predecessor. It’s unbelievably fast. It runs an entirely different model than any of its predecessors. It is cross platform – even running on Linux and OSX. This is indeed a new Microsoft. What is ASP.NET 5? ASP.NET 5 is a new version of ASP.NET that has been built from the ground up with performance in mind, it is modular, and supports multiple platforms such as Windows, OSX, and Linux. ASP.NET 5 no longer contains Web Forms, it is purely MVC based and supports both C# and VB.NET. This may be a difficult point for some. Going forward, there was a lot of baggage Web Forms carried around and it was an abstraction to the web, which isn’t how most modern frameworks work. As such, MVC...
