Somehow, I want to write a blog early in the morning;Xcode code block
During development, I don't want to write too much code. Then I will use this method to simplify the Code, including the MVVM framework, which also reflects the garbage code in C; in fact,
Problem: a project is being developed today. It requires that when the slave block is saved, the field data of the master block changes and is saved to the database. Originally, it was assigned a value from the pre-insert trigger of the block. The interface data has changed but is not saved to the data table. However, the data remains unchanged during the re-quer
How to solve the blank spacing and inline-block spacing of inline-block elements
In the morning, someone raised the following question in his blog: "The li element inline-block is horizontally arranged and there is an unknown gap ", I believe you have encountered this situation when writing pages.
I usually float li in this case, so there is no gap. However, ther
Block chain enthusiasts (qq:53016353)
BitPay Open source their Bitcore library package, we can use it to send information based on Node.js to the block chain. The library package allows us to produce bitcoin transactions without having to spend a few days downloading the complete block-chain ledger. Imagine Bitcoin and block
Today, the jquery blog encounters the relationship between the CSS document stream and the block-level inline element (Inline). Recently, I have been working overtime, having poor sleep and getting confused. The simple problem is complicated.There are too many projects, and some need to work together with colleagues. Some need to be put into error, big head.Document StreamDivides the form from top to bottom into one row, and emits elements from left t
It is known that the properties of Display:inline-block are not supported in IE6, so let's take a look at the effects of block elements and restrained elements in IE6 and resolve compatible methods:
The HTML is as follows://Use div to represent block element A to represent inline element under only set Display:inline-
Extend a question: how to achieve the effect of display:inline-block under IE block elements?
There are two ways of doing this:
1, first use the Display:inline-block attribute to trigger block elements, and then define the Display:inline, so that the block element presente
Recently the latest Linux kernel has been released to LINUX-3.19-RC6, according to Linus's release note, about once again after a RC7 version can be formally released. The biggest change to the Linux 3.19 kernel at the block level is the addition of a multi-queue block layer to better support devices like NVMe that support the multi-queue mechanism. The so-called multi-queue mechanism is that in the case of
What does Bumong do?
Bumong is a digital asset network built using block-chain technology, where any asset-owning institution/individual can distribute its digital assets (such as digital gold, credits, game equipment, etc.) on the network, and the assets can be freely convertible and circulated in the network.
The transaction flow of the assets on the chain will not depend on any centralized system, because the server and node are deployed and maint

signature, and the signature is stored in the transaction input. To verify a signature, we need three things: a signed data signature public key
In simple terms, the validation process can be described as checking that the signature is made from the signed data plus the private key, and that the public key happens to be generated by the private key. The data signature is not encrypted and you cannot reconstruct the data from a signature. This is a bit like a hash: you run a hash algorithm on th
