Chromecast has a compact form factor (a bit larger than a memory stick). For operation one needs a Wi-Fi connection and a TV with an HDMI port. Chromecast works with Android and iOS mobile devices, as well as with laptops (including Chromebook), and Mac and Windows PCs.
Well, how could we ‘boost’ privileges on Windows? First of all, we should say that there were found, lately, a lot of vulnerabilities regarding fonts parsing which make the process of privileges elevation rather simple as long as we have a proper exploit. If you use the Metasploit then you need only one command to get the system shell. However, it will only work if the system is not fully patched. In case if the machine has all the updates installed, despite the Linux, we will not be able to find SUID-binaries in here, furthermore the environmental variables usually do not transmitted to services or processes with higher privileges. So, what we can do then?
I guess you have heard about Evilgrade framework that allows to “fix” the update mechanism of the most popular programs (Windows update, Apple update and so on and so forth) by replacing valid files with malicious ones. You probably think that only the application’s updates are vulnerable? Well, you are wrong. I shall be honest with you, it is not that secure to download files from the web as it might be seemed from the first sight. Don’t believe me? Then look, or better say, read.
What is memcached?
But at first let us consider a small introduction. So memcached is a free and open high-performance distributed system for caching objects in memory. It is a storage of “key-value” type located in the operating memory and designed for small “portions” of arbitrary data (string values, numerical values, not infrequently serialized objects in the form of string values) such as results of queries to DB, results of API calls or generation of pages. In addition, memcached is a fully open development, is assembled and operated under UNIX, Windows, OS X and distributed under an open license. It is used by many popular web projects, for example, LiveJournal, Twitter, Flickr, YouTube, Wikipedia, etc. It is a normal network service with host-base authentication, which is operated in loopback interface on port 11211. memcached daemon supports UDP- and TCP-sockets and provides two different protocols for interaction with itself: text and binary. I suppose that this is all what we are to know about the patient so far.
It often happens that the costs of the project’s hosting service are higher than its other living expenses. It specifically refers to those projects using Amazon AWS extensively. But far from everyone knows that Amazon delivers various means to allow its users to pay less for the use of AWS services.
In this paper, as I am an active enthusiast of Joao Dias, a Portuguese application developer, and his motto: “Automate your life,” I will show how you can make your life much simpler, automate the problems requiring communication between your smartphone and a computer, another smartphone or a tablet PC.
In our work, we are faced with very different projects. In one way or the other, many of them could be called “high-load projects”. If you spend some of your spare time on categorizing these projects and discard such ordinary things as second-rate online stores while roughly grouping what is left, you can come up with an approximate classification. It includes four types of high load:
- By the number of requests (banner networks);
- By traffic (video services);
- By logic (complex back-end calculations);
- Mixed (everything that fell into several categories).
Now, let’s have a closer look at them.
