Pros and Cons of Monocrystalline vs Polycrystalline solar panels

https://www.solarreviews.com/blog/pros-and-cons-of-monocrystalline-vs-polycrystalline-solar-panels

Saved by uncleflo on December 20th, 2019.

There are 3 types of technology utilized in the solar panels available on the market today, these are monocrystalline, polycrystalline, and thin film amorphous. As the names suggest Monocrystalline and Polycrystalline are both types of solar cells that are made from crystalline silicon. Almost all quotes you will get when considering buying solar panels for your home will use crystalline solar panels. 2-3 years ago the most common type of solar panel used in residential solar installations in America were monocrystalline solar panels but in the last three years polycrystalline solar panels have become the most commonly used solar panels in residential solar installations in America.

This Photographer's Passport Photo Shoots Are... Different

https://petapixel.com/2019/08/16/this-photographers-passport-photo-shoots-are-different/

Saved by uncleflo on December 19th, 2019.

Photographer Max Siedentopf has a new project that examines one of the most boring types of photography: the passport photo. The series shows that even though passport photos need to be boring, the photo shoots themselves don’t.
Official passport photo requirements are extremely restrictive and specify the exact framing (centered with the subject facing straight on), lighting (a clear background with no shadow), and facial expression (no smiling). “It seems almost impossible for any kind of self-expression,” Siedentopf says. His project, titled Passport Photos, “tries to challenge these official rules by testing all the things you could be doing while you are taking your official document photo.”

Choosing the Right Switch: Know Your AC from Your DC

Saved by uncleflo on December 18th, 2019.

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true. Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for designers and engineers to understand how to pick the right switch for their product.

Boatworks Today | Boating Help For The DIY

Saved by uncleflo on October 12th, 2019.

Welcome to Boatworks Today, a show supported by viewers like you! Hey everybody, my name is Andy Miller and I am the creator of Boatworks Today… A little bit about myself and this show! I went to college at St. Norberts just outside of Green Bay (GO PACKERS!) and finished up there with a BA in Psychology and Sociology. Finding out a little too late into the curriculum, I decided that I didn’t really want to spend the rest of my life listening to people complain about themselves (yea, I had some internships that left a bad taste in my mouth). So, after graduation I was off to figure out what it is that I REALLY wanted to do with my life. I bounced around a bit, met the lovely person who is now my Wife, bought a sailboat and we lived on it for a while. Became a scuba instructor, but decided that boats were something that called out to me. I took an entry level apprenticeship position at one of the local marinas and after roughly 7 years with them I decided to pull the trigger and venture off on my own. Miller Boatworks was created, and the rest as they say is history! MBW focuses on cosmetic repair (gelcoat, paint, fiberglass) as well as custom woodworking & refinishing and complete boat restoration..

IPX Rating System: What It Means And Why You Should Know | Gear Mashers

https://gearmashers.com/ipx-rating-system-what-it-means-and-why-you-should-know/

Saved by uncleflo on September 9th, 2019.

The IPX Rating System is used to evaluate how resistant products are to environmental conditions. Many cycling and camera products often come with an IPX rating letting the consumer know how well an item will hold up under certain environmental conditions. The IP (Ingress Protection) numbers are written as IPXX, where “X”s are placeholders for numbers. The first “X” represents solid (dust/particle) resistance and the second “X” represents liquid resistance (water). When looking for cycling equipment or photography equipment, those products that have a higher IPX rating will be able to withstand the elements for longer periods of time without failure.For those who commute by bike, an IPX4 or greater will help keep your gear dry.

(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.

Saved by uncleflo on July 11th, 2019.

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.
