how to get a blinking cursor instead of a selection

$('.inptitle').dblclick(function(e){e.preventDefault();$(this).attr('readonly', false).focus();});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><input type='text' class='inptitle' value = 'TITLE' readonly = true>You would need to take the focus away and put it back after the browser had time to process the read-only change and additional change of that focus. That will take care of the blinking.To have an empty selection, you could briefly change the text and put the original back immediately.Here is how that would...

Detecting a product within an image

I want to detect a product within an image using cloud vision. If the product is too small relative to the image, then the algorithm does not detect it. For example, if I used an image of a product, it correctly labels it as a product but when I use a image of a person holding that product, it details plenty of (good) info about the person holding the object but fails to identify the object. Is there a way to force it?You can use this image to test it using the Cloud Vision Web UI: https://img.bleacherreport.net/img/images/photos/003/758/947/hi-res-bc77cb085652783632d48c3...

ServiceStack OrmLite Is it a error to use UserAuthRepository.CreateUserAuth inside a transaction

I have a complex workflow where I want to create rows in several tables in one transaction.One of the operations is to create a new UserAuth (from ServiceStack Authentication feature). I assume that all the database operations in a transaction should operate on the same connection, and if that is true, then I think it may be a problem to call UserAuthRepository.CreateUserAuth inside a transaction because it looks as if it uses its own connection. So my question is whether if the creation of a UserAuth will be part of the transaction or not when I have code like shown below....

CSS editor which expands one-line declarations on editing

Is there a CSS editor which automatically expands one-line declarations as multi-line declarations on focus ? To clarify my thought, see example below:Original CSS:div#main { color: orange; margin: 1em 0; border: 1px solid black; }But when focusing on it, editor automatically expands it to:div#main { color: orange; margin: 1em 0; border: 1px solid black; }And when it looses focus, editor again it automatically compresses it to one-line declaration.Thanks. If you are using Visual Studio you should be able to do a close approximation of this:You can change how CSS is...

How can I throw a duplicate key exception?

I am using hz 3.10.1 version. I would like to know will hazelcast throw a duplicate key exception when multiple threads try to insert the same key? Our scenario is only allowed 1 key to insert. Hazelcast maps are thread safe by design, alike to java COncurrentHashmap in that sense. So there will be no exception and both put operations will happen one after another.OTOH, if you want to ensure to insert each key only once, maybe you can use putIfAbsent method of Hazelcast map.

Pre processor: #if comparing two values

I was working on setting up a UART for ATmega168 micro controller. My first code didn't work. While checking on that I came across an header file used in a working program. It uses preprocessor directives. It was quite confusing for me, so I decided to run it in a c compiler and check outputs.#include <stdio.h>#define F_CPU 1000000UL#ifndef BAUD /* if not defined in Makefile... */#define BAUD 9600 /* set a safe default baud rate */#endif#define BAUD_TOL 2#define UBRR_VALUE (((F_CPU) + 8UL * (BAUD)) / (16UL * (BAUD)) -1UL)#...
