As part of the program house keeping must be performed on these objects roughly every five minutes, for this purpose I've placed them in a DelayQueue implementing the Delayed interface, allowing the blocking functionality of the DelayQueue to control house keeping of these objects. Upon new, an object is placed on the DelayQueue . Upon update, the

The application I'm developing uses 10-12 background threads which gets system information or makes HTTP request. I also use some JNA and JNI code. When i limit the heap size to 40 MB, it's fairly enough and the application runs without a problem with total ~100 MB memory. However since Oracle is dropping support for Java 7 in April, I decided to upgrade the application to Java 8, the upgrade went smoothly, not much code change required, but i noticed the total memory consumption

The dependencies between these steps are driving me crazy. With higher-half, the kernel is linked at its virtual address and so the options I've come up with are 1) enable paging in assembly, which would involve following all

Why is first order FRP useful with React and higher order not so useful ? Maybe higher-order-ism is not needed with React ? So in return one can keep the time travelling debugger ? In other words: React is a function that takes a state and gives back a view. FRP is a way to declare and execute a state machine. These are orthogonal concerns, so why not combine them ? EDIT: If i compare this https:/

But separate fields for a user to specify a minimum/maximum. public class FinanceModel{ public int MinimumCost {get;set;} public int MaximumCost {get;set;} } So I need to ensure that MinimumCost is always less than Maximum cost. 回答1: You can use a custom validation attribute here is my example with dates. But you can use it with ints too. First, here is the model : public DateTime Beggining { get; set; }

Yet as it works as expected, TS is complaining that "Return type of exported function has or is using private name "Anonymous class". Function in question: export default function wrapperFunc ( WrappedComponent: typeof React.Component, ) { return class extends React.Component { public render() { return ; } }; } The error is reasonable as the

Here's what I tried: ffmpeg -i a.mov -an -crf 11 -preset slower -pix_fmt yuv420p -vcodec mjpeg -f mov -y b.mov For H.264 encoding the -crf and -preset flags generate higher quality. But that doesn't seem to work for MJPEG. 回答1: Use -q:v By default for MJPEG ffmpeg will probably use the default of -b:v 200k . This was fine when it was set as the default more than 10 years ago (I'm guessing the age), but not anymore. You
