Research meets industry: A mine planning methodology for space | FNR – Luxembourg National Research Fund
Saved by uncleflo on September 4th, 2022.
When we wrote about Miguel Olivares Mendez in the 2017 edition of Spotlight on Young Researchers, the researcher was working on an FNR JUMP project, focussing on developing algorithms for autonomous drones. The robotics scientist has continued to build his research career in Luxembourg – 5 years later, Miguel is a Professor leading a research group with a focus on space robotics. Luxembourg start-up LuxAI, with their socially assistive robot QTrobot, has been making waves on an international level since it was created. The FNR has supported the project from its inception through the development of a prototype, helping bridge the gap between lab and commercialisation. We speak to LuxAI founders Dr Pouyan Ziafati and Dr Aida Nazarikhorram about the LuxAI journey so far; how QTrobot came to be and how parents can now have a QTrobot at home.

Term Frequency and Inverse Document Frequency (tf-idf) Using Tidy Data Principles
Saved by uncleflo on December 23rd, 2018.
A central question in text mining and natural language processing is how to quantify what a document is about. Can we do this by looking at the words that make up the document? One measure of how important a word may be is its term frequency (tf), how frequently a word occurs in a document. There are words in a document, however, that occur many times but may not be important; in English, these are probably words like “the”, “is”, “of”, and so forth. We might take the approach of adding words like these to a list of stop words and removing them before analysis, but it is possible that some of these words might be more important in some documents than others. A list of stop words is not a sophisticated approach to adjusting term frequency for commonly used words. Another approach is to look at a term’s inverse document frequency (idf), which decreases the weight for commonly used words and increases the weight for words that are not used very much in a collection of documents. This can be combined with term frequency to calculate a term’s tf-idf, the frequency of a term adjusted for how rarely it is used. It is intended to measure how important a word is to a document in a collection (or corpus) of documents. It is a rule-of-thumb or heuristic quantity; while it has proved useful in text mining, search engines, etc., its theoretical foundations are considered less than firm by information theory experts.

Marco Bonzanini - Mining Twitter Data with Python (Part 1: Collecting data)
Saved by uncleflo on February 19th, 2018.
Twitter is a popular social network where users can share short SMS-like messages called tweets. Users share thoughts, links and pictures on Twitter, journalists comment on live events, companies promote products and engage with customers. The list of different ways to use Twitter could be really long, and with 500 millions of tweets per day, there’s a lot of data to analyse and to play with. This is the first in a series of articles dedicated to mining data on Twitter using Python. In this first part, we’ll see different options to collect data from Twitter. Once we have built a data set, in the next episodes we’ll discuss some interesting data applications. Update July 2016: my new book on data mining for Social Media is out! Part of the content in this tutorial has been improved and expanded as part of the book, so please have a look. Chapter 2 about mining Twitter is available as a free sample from the publisher’s web site, and the companion code with many more examples is available on my GitHub

Peru last week initiated a new program that will provide electricity to more than two million of its poorest residents using solar panels. Energy and Mining Minister Jorge Merino said that the program will allow 95% of Peru to have access to electricity by the end of 2016. Currently, approximately 66% of the population has access to electricity.

Bitcoin Mining Contracts - Cloud Hashing
Saved by uncleflo on May 15th, 2014.
Who We Are: Cloudhashing was founded in February 2013 to take all of the hard work and complexities out of Bitcoin Mining. Great relationships with hardware manufacturers allow us to consistently offer the best pricing and highest potential returns to our customers. How You Earn Bitcoin: Cloudhashing provides an opportunity to potentially earn more bitcoins for your dollar than buying them outright. The appeal of mining Bitcoin rather than buying is to receive bitcoins at wholesale prices rather than market price. We work with customers for economies of scale to receive better prices on hardware, power and data center space, and in turn we share in the potential returns that mining offers.
NSFW: Reddit Women Are Getting Naked for Bitcoins

The future of sexuality is here, and boy it's predictably sad and weird: girls stripping for Bitcoin tips, a virtual currency that's not really worth anything. Start mining yer coins, boys! Welcome to GirlsGoneBitcoin. Of course, as FWD's Katie Notopoulos reports, this is taking place on Reddit. Where else would the pretense of paying via super-encrypted pseudo-currency be a turn on.

Welcome to Coinotron, bitcoin and namecoin mining pool
Saved by uncleflo on May 10th, 2013.
During last weeks difficulty has rapidly risen making solo mining practically impossible. Only big miners with dozens of GPU cards have a chance of generating block in few days. Average miner with 2 graphic cards working 24/7 must wait about 90 days for a block and 50 BTC reward. Only reasonable alternative is to work together with other miners. We have created Coinotron.com to support that joint effort. We invite you to join Coinotron. Rules are simple: Proportional payouts. For each BTC block generated in our pool we get 50 BTC. Next we split these coins between miners proportionally to amount of work delivered. Coinotron advantages: security is our priority, users passwords are hashed and salted, we are startup pool, so odds of DDOS attack are at this moment slight, anti-cheating score system punishing pool-hoppers, long poll support ( mining efficiency raises about 2% ), automatic payouts

Litecoin Mining Calculator
Saved by uncleflo on May 10th, 2013.
Litecoin is a peer-to-peer Internet currency that enables instant payments to anyone in the world. Litecoin can be mined with consumer-grade hardware. Hashrate - This is a measure of how quickly your hardware can do the work of Litecoin mining. You can find out the expected hashrate of your hardware at the mining comparison page. Hashrates in this calculator are expressed in kilohashes per second (Kh/s) each of which equals 1000 hashes per second. Megahashes (1,000,000) and gigahashes (1,000,000,000) are commonly used to describe larger Litecoin mining rigs and the total network hashrate.

How to get started using your GPU to mine for Bitcoins on Windows
Saved by uncleflo on May 8th, 2013.
This post is aimed mostly at people who are already familiar with Bitcoin (Wikipedia page), and would like to get started using their GPU(s) to mine for bitcoins in a Windows environment. Just some quick terminology: miner = program which is external to bitcoin-qt.exe that uses your graphics card to perform calculations; your GPU is much more efficient at the type of calculations bitcoin does than your CPU

If you're thinking buying mining hardware, read this first
Saved by uncleflo on May 8th, 2013.
If you've used one of the generic bitcoin profitability calculators, you've probably been surprised by the projected income from Bitcoin mining. The profitability numbers can be shockingly high for just buying a video card, putting it in your PC, and running a program 24/7. But all of the online calculators I've seen omit the biggest hurdle: Difficulty increases. The bitcoin network is designed to produce approximately 2016 blocks every two weeks. With high performance hardware becoming cheaper and more widespread and more users jumping on the mining bandwagon, the only way to keep the block production rate constant is to make it harder. Thus, every two weeks the difficulty adjusts to slow down or speed up production to match this 2016 blocks / 2 weeks target rate. This almost always goes up.

Beginner's Guide
Saved by uncleflo on May 7th, 2013.
Starting this thread when I was trying to consolidate different rigs into my building thread and it quickly became more like a newbies guide and I thought why not. I realized as I kept including the different threads and sites I've been to thinking that it'd help people who would go to my thread it started turning into this. I'm not an expert on Bitcoin or anything, in fact I consider myself a newbie at this point of time. However being a newbie myself, I found that information regarding this relatively new and very technical topic is scarce and difficult to find. After many days of searching the net and forums I found myself still within the vicinity of where I started albeit I'm getting the general idea of how things work, also I've found that over the few days I've been reading this forum that the same questions kept getting raised and people would have to keep answering the same questions from newcomers which might get a little frustrating sometimes.

BTC Guild - Bitcoin Mining Pool (95% PPS/97% PPLNS)
Saved by uncleflo on April 23rd, 2013.
BTC Guild is a Bitcoin Mining Pool, and one of the oldest remaining Bitcoin pools. BTC Guild tries to provide a simple but clean interface, full of all the statistics that a savvy miner would want to see. BTC Guild offers two methods for miners to receive payments. Pay-per-Share (PPS) provides miners with the lowest variance of any pool payment system, at a 5% fee, and Pay-per-Last-N-Shares (PPLNS), at a 3% fee, which has some variance, but also includes block transaction fees.
Bitcoin shared mining @ BTCMine.com
Saved by uncleflo on April 23rd, 2013.
BTCMine is a pooled Bitcoin mining server. Pooled mining allows many miners to work together and therefore reduce variance in their Bitcoin reward over time. This is achieved by fairly distributing the reward from any blocks found by the server according to how much work you as an individual miner have contributed.
