Relatively recently, we saw the release of Red Hat Enterprise Linux 7, a distribution that is rightly considered to be the number one in the corporate sector. Without waiting for its clones, we decided to look at what is new in this giant of open source world which was able, at some point, to combine the seemingly incompatible – making money and using an open-source model.
Bug Bounty—vulnerability reward programs for vendors—become more and more widespread. And sometimes, vulnerabilities search detects some evidently insecure areas (e.g., self-XSS) the threat of which is hard to prove. But the larger (or even the smarter) is the vendor (e.g., Google), the more willing it is to discuss, to detect the indicated vulnerability and to reward if successful. This article is a collating of complex situations and the ways to prove a threat and to make the Internet more secure.
Only lazybones know nothing about Cydia today. Such words as jailbreak, tweak and unofficial app store have long ago come into general use of every more or less competent user of an i-device. On the other hand, it would be a blasphemy not to tell about Cydia, so we decided to take a different way collecting entire info about novelties, utilities and other interesting things found in the expanses of this app store.
OpenStack is a very fashionable word in today’s IT media space. Virtually everyone heard about it, but not so many have seen it in action. Moreover, only a few dared to taste it in a “serious way”. In our company, we took this risk and, today, I’ll tell you what happened to us and why the fashion often runs ahead of prudence and stability.
If I started the article with describing all the advantages of cloud storage of data, you would think that I had been just thawed after twenty years of anabiosis, or that I use overdoses of hypnotics :). Therefore, I will put it briefly, in a programmer-like fashion: when I was faced with the task of making a program that could operate without being bound to the API of a particular service, enabling work with files located in a number of storage spaces (its purpose was backup), it turned out that it was not that simple. I decided to tell you about all the intricacies and pitfalls of that work in this article.
Often, you find yourself in a situation when it is not convenient to use your smartphone or get it out of pocket, such as when it rains, while driving a car, at a meeting… Or you may simple feel a bit lazy to get up from a warm couch to see what has arrived to your phone. In this article, I’ll show you how to configure the notifications, customize and use the full power of Pebble, one of the most popular smart watches.
As you can remember ( and as a must to remember for each good administrator) it is not a good idea to work as a root user on Linux. In a perfect world you should use it only to configure a server, to install or to update software, by and large, only for purely administrative purposes. The problem is that we live in the real world that is, actually, quite far away from a perfect one. So, the situation is quite common and, generally, because of negligence, wherefore, the Linux users had no choice but to figure out how does their software works. However, if you know how does the system work and understand its safety mechanisms then you will never work as a root user. Anyway, today we are going to review the ways of raising authorities up from the unprivileged user to a root one, unlike the situation with Windows where we were considering the ways of running with administrative privileges. So, let’s start.
