SolrNet, the C# client for Apache Solr, has a new release: 0.5.1. The current release aims to include a breaking change with the latest versions of Solr 4.x in which multiple collations are returned by Solr. I am currently working on getting it to Nuget.
The other day I needed to finish a task I had in one of my servers and needed to remote into one of my Cloudera QuickStart VMs to run a test while on a trip. So I installed TeamViewer to access it. Steps are simple: # Click on Download TeamViewer link for RedHat, CentOS, Fedora, SUSE to get the rpm package from the downloads page https://www.teamviewer.com/en/download/linux/ Open terminal and go to downloads directory sudo yum localinstall teamviewer_12.0.71510.i686.rpm And then start with teamviewer
In my Pluralsight trainings, Getting Started with Enterprise Search using Apache Solr and Implementing Search in .NET Applications, one of the things that I make quite a bit of emphasis is on how important search is, yet it is one of the most misunderstood functions of IT and development in general. In this post I will show you an example of how a potentially good app is a pretty bad app mainly because of its search capabilities. It is so much the case that in Twitter Pluralsight selected this phrase to tweet about the release of my course as you can see here: But now let’s get to the sample. Here’s the scenario: Problem: Life is busy. No time to go to the supermarket Solution: use your grocery store’s web site to purchase your food and it gets delivered home the next day. Charming idea, did not work with Webvan, but it seems to be doing quite well for Amazon and in my home town one of the major supermarkets is doing it in a more controlled way with a good delivery service, all for $10. Not too scalable, but for a MVP it is ok. (Read Lean Startup if you […]
Something that really annoys me, especially when connecting remotely is how the terminal blanks when installing Cloudera Manager in Linx CentOS Well, there is a very simple fix, simply run the following command and the terminal will not go black sudo setterm -blank 0
Look around you. Look closer. Pay more attention. What do you see? When I look around me I can see activity trackers, digital cameras, smart watches, interconnected devices, virtual reality gadgets, wearable technology, smart elevators, energy saving light systems, intelligent traffic lights, smart cars with over the air updates and that can gather data on your driving habits, intelligent houses, eco friendly buildings and more. All of these generate massive amounts of data. But let’s hold that thought for a minute. Now this is just what’s happening around you. What do you have in your pocket or in your hand right now? Most likely a smart phone. It is your portal to the digital world and even though it became second nature – pretty much everyone walks around with a phone in their hand now a days – it is a relatively new phenonem. It is highly likely that you use your smartphone constantly to check Facebook, Twitter, Instagram or search the web using Google among a few other applications. This generates humongous amounts of data. Let’s throw out a few numbers just to put it in perspective. Facebook has 1.6 billion users- yes, that is with a B – […]
Big Data Big deal? Big hype? Or big change in our world? I think that the answer can be all of the above. “Hype” you might be thinking? Well, here is the deal. Our world has changed in unimaginable ways. The amount of information created daily is reaching levels that just a few years ago would’ve been considered science fiction or even plain old crazy. Lots and Lots of Data To make it even more interesting, a lot of it is unstructured data. Which can be kind of a problem if we think about it, because the success of relational databases has taught a lot of us to think in a columnar and relational way. And this is not bad… at all. It is nice to have all your data and metadata organized neatly. You can use select, join, where, group by and more to get what you need. But the success of relational databases can also create a blind spot for many. Just a few days ago I was talking with the VP and cofounder of a company related to migrations and artificial intelligence software whose company has faced success (as well as a few failures or learning experiences) […]
