mysql – connection example
Mysql is a database, and to gain access to the data within C++ you will need to be able to “talk†to the database via queries (just like on the mysql command line interface e.g. select * from tablename), the connection process is very similar to the command line interface you will need to supply connection details as in hostname (localhost normally), username, password, database to use and also there are other details that you can pass e.g port number more information can be gained f...

A guide on installing and running Clickhouse on macOS
ClickHouse is a high-performance open-source columnar database management system developed by Yandex. Here are some of the key features of ClickHouse: Columnar storage: ClickHouse uses a columnar storage format, which allows it to efficiently store and retrieve data by column, rather than by row. This results in much faster query performance, especially for analytical and aggregate queries.

A Sip of Go Log
Logging is indispensable in any code that we need its support both in debugging and in statistics. However, a package that filled withfmt.Println/fmt.Printf printing various messages can never be considered a read-to-be-adopted package, which can be optimized by a simple change, using Golang’s native log package to print information to standard output or to a file. Then, how to apply the log package? Are there any limitations? If so, can we seek open-source packages? Let&rsq...
OpenLDAP Proxy -- slapd.conf
In the introductory post of OpenLDAP proxy, we mentioned that slapd.conf is the configuration file which tells the slapd service what to do. Apart from this, there is a dynamic way of configuring slapd where the configurations are stored in LDIF database. In the future, LDIF database will be the one for configuring slapd, the old style of slapd.conf is deprecated. The slapd.conf can be converted to LDIF style using the slapdtest command. slapdtest -f /etc/ldap/slapd.conf -F /etc...

API Design is UI for Developers
I’ve been thinking a lot about APIs and their design recently.I stumbled on this fantastic quote from Greg Parker: A programming language is a user interface for developers. Language authors should learn from HCI principles.22/02/2012 19:10 via webReplyRetweetFavorite@gparkerGreg ParkerWhen I first started learning C++ (back in the bad old days) I was convinced that any 1st year student could design a better programming language. One which behaved in a sane fashion without a lot of le...

A Tiny MySQL++ Tutorial; C++ and MySQL; MySQL++ Example
I wrote a post about how to install MySQL++ and I thought I will write a quick tutorial on how to use it too. This is a very basic MySQL++ program and it’s very self explanatory: #include <mysql++.h> #include <stdlib.h> using namespace std; using namespace mysqlpp; int main() { try { Connection conn(false); conn.connect("DB NAME", "DB HOST probably localhost", "DB USER", "DB PASS"); Query query = conn.query(); } catch (BadQuery er...
Best “must know†open sources to build the new Web
Here the dump of my ultimate collection of online Web development resources and directory, oriented for the Front-End user Interface (UI). HTML5 and all related open standards are moving fast, but for now, building a whole Website/WebApp on top of that can be very inconsistent, especially across various browsers experiences. So… how to embrace new awesome web technologies ? Now, as Web Developers and Designers, we have to build on top of more stable framework. It’s her...

Learning Go
This year I'm going to try a new programming language - Go. I had this notion that compiled, type based languages are overly complex and reduces developer efficiency. However, after doing some reading about Go, it appeared to take a different path from the rest and felt like something worth trying. Acquainting a programming language is a journey. First few steps you take with it will define your perception about it. These first few steps went well for me with Go and it felt lik...
