Connecting mysql Database in ANDROID using PHP & JSON

 To implement this tutorial you should have basic knowledge of how to run PHP script and start server.  If we talk about client-server architecture, client is Android device and in server side there is a combination of PHP Script and MySQL. In short, PHP Script sits in middle as shown in image. Lets suppose that we have a MySQL database named Employee, and a table int created, with the following SQL: CREATE TABLE `employee` (   `emp_id` int(11) NOT NULL auto_increment,   `emp_name` varchar(100) NOT NULL,   PRIMARY KEY  (`emp_id`) ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ; The PHP code will be very simple: Now Create Android Project :  The Android part is only a bit more complicated: -use a HttpPost to get the data -convert response to string -parse JSON data in to List In Your First Activity : O/P :

Jev: The Decision Layer Cutting AI Agent Costs

The expensive part of an AI agent usually isn't the final answer: it's the string of small decisions behind it. Every tool pick and "are we done yet" check is its own LLM reasoning call, and agent loops make dozens per task. Jev is a typed decision layer built to replace exactly those calls. Here's what that looks like inside a personal finance agent answering a spending question, and what it's worth evaluating for your own MCP stack. Key Takeaways Jev never executes anything: it only routes, labels, or checks; your existing LLM and code still do the real work. In a finance agent, it turns a spending question into a routed, labeled, fact-checked answer without extra reasoning calls. Adoption is shadow-mode first: test it against your current routing before it touches production traffic What Is Jev, and Why Are AI Teams Adopting It Now? Jev is a fast, typed decision model: send it a state and bounded questions, and it answers each in one of three fixed shapes: ...

Why Domain-Specific AI Agents Beat One Big Agent

Everyone is building agents right now. Real estate firms. Independent insurance brokers. Fortune 500 companies with budgets big enough to hire an army of consultants. Ask around and you'll hear the same story everywhere: "we're building our own agent." And yet almost nobody is asking the obvious question: why does the default approach keep failing? One large, general-purpose agent gets wired up to every tool the business owns. It impresses in the demo. Then it quietly stalls before production. There's a gap between what businesses want and what they're actually getting. They want AI woven into their data, their workflows, their day-to-day operations. What they get instead is one oversized agent trying to be a sales rep, a compliance officer, and a customer support line, all at once. That gap is an architecture problem, not a model problem. Key Takeaways The default "one big agent" pattern breaks down on context bloat, cost, fragility, and portability...
