Kar-go: Europe's first road-worthy autonomous delivery vehicle - CNN

https://edition.cnn.com/2019/07/26/sport/kargo-autonomous-ai-delivery-vehicle-supercharged-spt-intl/index.html

Saved by uncleflo on July 30th, 2019.

(CNN)If you're sick and tired of arriving home after a hard day at work to find yet another online delivery has gone AWOL, then a new autonomous delivery vehicle could soon be here to help. Kar-go is the brainchild of the United Kingdom-based Academy of Robotics, which describes it as "Europe's first road-worthy autonomous delivery vehicle." Using AI, this autonomous delivery vehicle offers customers an app -- similar to one used when ordering a taxi -- allowing them to choose when and where their packages are delivered. Earlier this year, Chinese startup Neolix also began mass production of its own autonomous vans, while in Houston last month, Domino's Pizza partnered with self-driving company Nuro to deliver takeaway food to customers' doors.

Tracking of stationary and moving objects is a critical function of Autonomous driving technologies. Signals from several sensors, including camera, radar and lidar (Light Detection and Ranging device based on pulsed laser) sensors are combined to estimate the position, veloctiy, trajectory and class of objects i.e. other vehicles and pedestrians.

It’s a few weeks after AWS re:Invent 2018 and my head is still spinning from all of the information released at this year’s conference. This year I was able to enjoy a few sessions focused on Aurora deep dives. In fact, I walked away from the conference realizing that my own understanding of High Availability (HA), Disaster Recovery (DR), and Durability in Aurora had been off for quite a while. Consequently, I decided to put this blog out there, both to collect the ideas in one place for myself, and to share them in general. Unlike some of our previous blogs, I’m not focused on analyzing Aurora performance or examining the architecture behind Aurora. Instead, I want to focus on how HA, DR, and Durability are defined and implemented within the Aurora ecosystem.  We’ll get just deep enough into the weeds to be able to examine these capabilities alone.

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

Saved by uncleflo on June 18th, 2019.

I’ve been dismayed to discover just how many software developers aren’t really completely up to speed on the mysterious world of character sets, encodings, Unicode, all that stuff. A couple of years ago, a beta tester for FogBUGZ was wondering whether it could handle incoming email in Japanese. Japanese? They have email in Japanese? I had no idea. When I looked closely at the commercial ActiveX control we were using to parse MIME email messages, we discovered it was doing exactly the wrong thing with character sets, so we actually had to write heroic code to undo the wrong conversion it had done and redo it correctly. When I looked into another commercial library, it, too, had a completely broken character code implementation. I corresponded with the developer of that package and he sort of thought they “couldn’t do anything about it.” Like many programmers, he just wished it would all blow over somehow.

Your code works, but is it safe? When writing code that will run across hundreds if not thousands of websites, you should be extra cautious of how you handle data coming into WordPress and how it's then presented to the end user. This commonly comes up when building a settings page for your theme, creating and manipulating shortcodes, or saving and rendering extra data associated with a post.

Containers: A Complete Guide | IBM

Saved by uncleflo on May 12th, 2019.

This guide looks at the importance of containers in cloud computing, highlighting the benefits and showing how containers figure into such technologies as Docker, Kubernetes, Istio, VMs, and Knative. A container is a small file that packages together application code along with all the libraries and other dependencies that it needs to run. By packaging together applications, libraries, environment variables, other software binaries and configuration files, a container guarantees that it has everything needed to run the application out of the box, regardless of the operating environment in which the container runs. A key characteristic of a container is that it is small and fast because it uses some of the underlying host operating system's resources to run rather than containing a whole OS of its own.

Once the seller has accepted your offer, ask them to take it off the market. They don’t have to agree to this, but doing so will shut out other potential buyers. Now you need to move fast – the seller will want to see progress so try to avoid any unnecessary delays in getting the surveys and other legal work done. Complete the lender’s application form and send them the documents they require – this will include proof of your ID, evidence of your earnings, proof of your address over the last few months and your bank statements, so have these ready. The lender will then arrange for a valuation to be carried out on the property. This allows them to work out how fair the amount you’ve asked to borrow is compared to what they deem the property to be worth.

How to Keep Polished Brass From Tarnishing - Hunker.com - By Brenda Priddy

Saved by uncleflo on February 23rd, 2019.

Brass will automatically start to tarnish if exposed to oxygen. The only way to prevent polished brass from tarnishing is to coat it with a layer of clear sealer that will prevent air from reaching the brass itself. Many brass surfaces come with this finish originally, but it can wear down over time. Refresh the coating every few years to keep the brass shiny and like-new without frequent polishing. A clear polyurethane sealer will protect the brass from oxygen exposure without causing discoloration.

NFS - which ports to open? - Storage - Discussions

Saved by uncleflo on December 23rd, 2018.

No problem connecting to NFS with firewalls disabled,but even with TCPView it's not obvious which ports require opening.
We've opened port 2049 for both UDP and TCP and all seems well, but there's a selection of ports mentioned across the web for NFS. So with XenServer just 2049? Sharing filesystems by NFS: Regardless of which choice is made for ID mapping you will need to adjust any firewall the system is using so that NFS clients can communicate with the server. You will need to ensure that the following ports are open before sharing any filesystem: UDP: 111, 1039, 1047, 1048 and 2049. TCP: 111, 1039, 1047, 1048 and 2049. See _this article_ Tobias

How TF-IDF algorithm determines keyword importance - arbitrue Blog

https://www.arbitrue.com/blog/tf-idf-algorithm-for-keyword-importance/

Saved by uncleflo on December 23rd, 2018.

There are many tools in the developer’s toolbox when it comes to automatic data extraction. A good example is TF-IDF algorithm (Term Frequency – Inverse Document Frequency) which helps the system understand the importance of keywords extracted using OCR. Here’s how TF-IDF can be used for invoice and receipt recognition. In this article we focus on other techniques in order to make this text file “understandable” to a computer. For this purpose, we must delve into the world of NLP or Natural Language Processing. We will focus mainly on how we can transform our file of raw text into a format that will easily be understandable by our algorithm. In a nutshell, TF-IDF is a technique for understanding how important a word is in a document which is often used as a weighting factor for numerous use cases. TF-IDF takes under consideration how frequent a word appears in a single document in relation to how frequent that word is in general. Search engines can use TF-IDF to determine which results are the most relevant for a search query.

Term Frequency and Inverse Document Frequency (tf-idf) Using Tidy Data Principles

https://cran.r-project.org/web/packages/tidytext/vignettes/tf_idf.html

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.

How can we find the tf-idf value of a word in the corpus?

Saved by uncleflo on December 23rd, 2018.

I am working on text classification using SVM. In a paper (Fuzzy Support vector machine for multi-class text categorization) the author has reduced the features(words) by applying the following criteria: "Eliminate the words that are ICF>log2, Uni<0.2 and TF_IDF<26". My question is how can we find TF_IDF value of a word. TF is a local measure and IDF is a global measure. TF_IDF gives different value for a word in each document. TF-IDF is the acronym for Term Frequency–Inverse Document Frequency. This metric aims at estimating how important is a keyword not only in a particular document, but rather in a whole collection of documents (corpus). Actually, a lot of common words like articles or conjunctions may appear several times in a document but they are not relevant as key-concepts to be indexed or searched. TF (Term Frequency) provides a measure about how frequently a term occurs in a document.

tf–idf - Wikipedia

https://en.wikipedia.org/wiki/Tf%E2%80%93idf

Saved by uncleflo on December 23rd, 2018.

In information retrieval, tf–idf or TFIDF, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus. It is often used as a weighting factor in searches of information retrieval, text mining, and user modeling. The tf–idf value increases proportionally to the number of times a word appears in the document and is offset by the number of documents in the corpus that contain the word, which helps to adjust for the fact that some words appear more frequently in general. Tf–idf is one of the most popular term-weighting schemes today; 83% of text-based recommender systems in digital libraries use tf–idf. Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document's relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields, including text summarization and classification. One of the simplest ranking functions is computed by summing the tf–idf for each query term; many more sophisticated ranking functions are variants of this simple model.

If I ask you “Do you remember the article about electrons in NY Times?” there’s a better chance you will remember it than if I asked you “Do you remember the article about electrons in the Physics books?”. Here’s why: an article about electrons in NY Times is far less common than in a collection of physics books. It is less likely to stumble upon the “electron” concept in NY Times than in a physics book. Let’s consider now the scenario of a single article. Suppose you read an article and you’re asked to rank the concepts found in the article by importance. The chances are you’ll basically order the concepts by frequency. The reason is simply that important stuff would be mentioned repeatedly because the narrative gravitates around them. Combining the 2 insights, given a term, a document and a collection of documents we can loosely say that:importance ~ appearances(term, document) / count(documents containing term in collection).

I realise when I first released this post, it was January, a time of year that not everyone is throwing themselves into water without a wetsuit. A lot of you have been asking about sustainable swimwear options again over the past month with this never-ending heatwave we are having, so I thought I’d update and repost this guide. With environmental issues becoming much more prominent in the mainstream media, a quick google into the textiles and fashion industries will provide you with endless reasons to choose slow fashion. If you didn't follow Fashion Revolution and the #whomademyclothes movement go and check it out, alongside the documentary The True Cost. The price is often more because these companies pay workers a fair living wage, and source sustainably grown and produced materials. I've been trying to buy everything I wear consciously and not fall into the consumerism trap too often (although I'm occasionally slip up and find myself on the high street, damn those glittery topshop dinosaur socks).

Richard and Roz Smith seem rather surprised to find themselves on board their Oyster 56, bobbing gently on a pontoon at Shamrock Quay, Southampton. It is the boat they have been refitting for the past nine months ahead of a “four-or-five-year” circumnavigation. They are surprised in part because the long, expensive fit-out work is finally drawing to a close (although there are winch bits on the saloon table and air-con ducting protruding from the panelling). But also surprised to be taking off for such an ambitious trip by themselves.

Living on a houseboat in London: living on the water is no longer an alternative lifestyle choice as Londoners look to rivers and canals for better value homes. Londoners looking for a central home on a budget are hitting the water — and avoiding stamp duty in the process. The number of Londoners resorting to living on boats has rocketed — with many driven off dry land by the high price of conventional homes. The number of boats registered to be moored on London waterways has increased by nearly 60 per cent in the past five years to almost 4,000, according to latest figures from the Canal & River Trust, which manages 100 miles of canals in the capital including the Grand Union and Regent’s Canals. Many other floating households are in private marinas or at moorings along the Thames.

London vies with Hong Kong and Monaco for the unenviable title of the world's most expensive city for housing. The average house price in the English capital is now nearly £600,000 ($787,000), and a study from the charity Shelter found just 43 properties affordable to people on an average income. Several of these properties were houseboats. Life on London's 100-mile network of canals, or 42-mile stretch of the River Thames, has become a popular option for beleaguered citizens, and such homes can cost as little as £20,000 ($26,500). But as more people swap apartments for houseboats, the popular, romantic vision is giving way to a harsh reality.

Drones are big business, and thousands of you would have received your very own for Christmas this year. The plummeting cost of components and the ease of buying remote controlled aircraft off the Internet has skyrocketed the use of consumer drones across the globe. Headlines are made every day, whether that’s new drones at CES, drones almost hitting passenger jets, or drones spying on unassuming victims. The CAA (Civil Aviation Authority) has already prosecuted two drone operators in the UK for breaching safety regulations, with numerous other investigations ongoing. In October, a man was arrested for operating a drone over Manchester City’s football stadium in a match with Tottenham Hotspur.
