Turing's Man Blog - Turing's Man: from data center through IT to hobbies, general thoughts and reflections, altogether. http://www.wsww.turingsman.net/my-blog-list Mon, 21 Aug 2017 21:21:21 +0000 Joomla! - Open Source Content Management en-gb Big Data. A few thoughts on my mind http://www.wsww.turingsman.net/my-blog-list/185-from-big-data-basics-to-data-pollution http://www.wsww.turingsman.net/my-blog-list/185-from-big-data-basics-to-data-pollution

There is an interesting blog post by Gli Allouche – it was recommended on the CITM group on LinkedIn – "Big Data 101". To be honest, Big Data, on the very first impression, seems to be yet another buzzword, like previously promoted "cloud computing" term. Well, definitely this is not a new, ground-breaking technology, more an approach to gather and process the huge amounts of data. So, what it is about in fact? Why all the buzz around Big Data?

IT Future Expo 2014 on National Stadium, Warsaw, Poland. A short report http://www.wsww.turingsman.net/my-blog-list/184-it-future-expo-2014-on-national-stadium-warsaw-poland-a-short-report http://www.wsww.turingsman.net/my-blog-list/184-it-future-expo-2014-on-national-stadium-warsaw-poland-a-short-report

Something I almost forgot about… The first edition of IT Future Expo from 10th to 11th of June, 2014 on National Stadium in Warsaw, Poland took place. This event was connected with two other important occasions – first, IT Future Awards – IT Leaders 2014 contest which was finalized with official evening gala on 10th of June, where the results of previous on-line voting were presented and, at the same time, IT Future Expo was initiated; second, IT Future Congress, a conference related to IT market trends in Poland which held place on 11th of June, alongside the main expo. Great place, great moments to remember…

Scrum vs Waterfall – two different approaches to software development http://www.wsww.turingsman.net/my-blog-list/183-scrum-vs-waterfall-two-different-approaches-to-software-development http://www.wsww.turingsman.net/my-blog-list/183-scrum-vs-waterfall-two-different-approaches-to-software-development

There are many software development methodologies (or system development methodologies – which in my personal opinion is even better term) in the field of software engineering. Debates on their pros and cons are countless, the same way like other discussions of such kind – for example: "which programming language is better"? The answer is simple – this methodology is better in given case, which suits the requirements and conditions best. The problem is – it is hard to choose the proper one. Therefore, to stay current with the latest trends, it is a good idea to watch the shortest (I've ever seen) introduction to Scrum – an iterative and incremental agile software development framework for managing product development – and compare it to the well-known Waterfall model.

From the Heartbleed bug through TOR to the OpenSSL fork. CVE-2014-0160 discussed http://www.wsww.turingsman.net/my-blog-list/181-from-the-heartbleed-bug-through-tor-to-the-openssl-fork-cve-2014-0160-discussed http://www.wsww.turingsman.net/my-blog-list/181-from-the-heartbleed-bug-through-tor-to-the-openssl-fork-cve-2014-0160-discussed

In an interesting news from Ars Technica, which is directly related to recently discovered OpenSSL Heartbeat Vulnerability (CVE-2014-0160), we can read: […] More than a week after the revelation of a fatal flaw in the most recent versions of the OpenSSL cryptographic library—the encryption at the heart of much of the Internet's security — a large number of systems associated with the Tor anonymizing network remain unpatched and vulnerable to attack […]. However, there are more interesting consequences, of course.

Submarine cabling. The core of our global connectivity http://www.wsww.turingsman.net/my-blog-list/180-submarine-cabling-the-core-of-our-global-connectivity http://www.wsww.turingsman.net/my-blog-list/180-submarine-cabling-the-core-of-our-global-connectivity

Having in mind that more than 70% of Earth’s surface is covered with the oceans, we can ask a question – how we wired our planet to allow global connectivity? For most of the time we use Internet services – doesn’t matter where in the world, we assume there is a way to establish a connection (which is not exactly true, of course). Internet – for good – seems to be a part of our reality right now. In developed countries we cannot imagine proper living without the Internet services, the same way as we think about water availability or electricity. Honestly, the things are not so easy, even if we don’t see how much effort is required to provide all these goods worldwide. So, if we would like to see where the most important cables are placed, there is a good reference available on the web…

Lenovo will use Motorola's name to enter the US smartphone market http://www.wsww.turingsman.net/my-blog-list/179-lenovo-will-use-motorola-s-name-to-enter-the-us-smartphone-market http://www.wsww.turingsman.net/my-blog-list/179-lenovo-will-use-motorola-s-name-to-enter-the-us-smartphone-market

According to the Verge’s article (by Jacob Kastrenakes), Google sells Motorola to Lenovo. This is "just in time" information, as we have learnt that Lenovo bought x86 server business from IBM quite recently. This seems that there will be a new – huge – player on the IT hardware market. Lenovo will be able to cover the following market sectors: x86 servers, smartphones and, thanks to the deal from 2005 when Lenovo acquired ThinkPad business from IBM, they currently are doing quite well with their notebooks. So, what exactly we can read in the Verge’s article to update our yesterday thoughts?

Microsoft joins OCP project, IBM sells its x86 server business. Will cloud services boost the data center market changes in 2014? http://www.wsww.turingsman.net/my-blog-list/178-microsoft-joins-ocp-project-ibm-sells-its-x86-server-business-will-cloud-services-boost-the-data-center-market-changes-in-2014 http://www.wsww.turingsman.net/my-blog-list/178-microsoft-joins-ocp-project-ibm-sells-its-x86-server-business-will-cloud-services-boost-the-data-center-market-changes-in-2014

Open Compute Project, OCP, which was announced by Facebook in April 2011 and presented on Turing’s Man Blog at the beginning of 2012, is going well, however, not so many news are published and publicly discussed in the industry. Why? That’s an interesting question. All in all, this seems to be very important initiative, which gained lots of popularity among, at least, some of recognizable industry leaders. Now, Microsoft decided to join Open Compute Project and share the designs of their servers and related technology. This might be an important moment not only for OCP, but also for the whole data center industry.
