Scan of a 1921 book about insectsP

See the original posting on Boing Boing

Public Domain Review calls our attention to the gorgeously illustrated 1921 Fabre’s Book of Insects.

Like Jacques Cousteau in the twentieth century, Fabre’s greatest accomplishment was perhaps to have brought out the beauty and drama in the lives of creatures that had hitherto been regarded with horror, if regarded at all. He turned his attention not just to bees, whose praises have of course been sung since the classical era, but to wasps, weevils, ants, glow-worms, caterpillars, and cicadas. He also sometimes wrote about wild flora and fauna, and in one rare chapter about his cats — all in prose characterized, a little like Cousteau’s, by a well-informed wonder at the natural world, appealing to both children and adults:

Few insects enjoy more fame than the Glow-worm, the curious little animal who celebrates the joy of life by lighting a lantern at its tail-end. We all know it, at least by name, even if we have not seen it roaming through the grass, like a spark fallen from the full moon. The Greeks of old called it the Bright-tailed, and modern science gives it the name Lampyris.

If you are planning on buying a Nintendo Switch, wait until next month for the new model

See the original posting on Boing Boing

Here’s a tip if you’re thinking of getting a Nintendo Switch — skip the current model (HAC-001) and wait for the HAC-001(-01), which offers significantly improved battery life.

From Ars Technica:

Switch model HAC-001-01 will last approximately 4.5 to 9 hours on a single charge, depending on the game being played, according to Nintendo. That’s a 38 to 80 percent increase from the 2.5 to 6.5 hours of the original model HAC-001. For The Legend of Zelda: Breath of the Wild, Nintendo promises an increase from approximately three hours of single-charge play on the old model to approximately 5.5 hours on the new model. For comparison, the Switch Lite will get three to seven hours on a single charge, and it can last four hours on Breath of the Wild, according to Nintendo.

This AI turns your headshot into a portrait painted by a master

See the original posting on Boing Boing

AI Portraits does an amazing job of creating original portraits based on photos of faces. The generative network was trained with 45,000 portrait images.

“Not only colors, but shapes, the lines of the face are completely redesigned by the model. In the above example, the model decides upon a Renaissance style, highlighting the elegance of the aquiline nose, the smoothness of the forehead.”

Notice how the AI didn’t show Isabella Rossellini’s teeth. I tried it with a photo where I’m smiling and got the same result:

According to the folks who made AI Portraits, “Portrait masters rarely paint smiling people because smiles and laughter were commonly associated with a more comic aspect of genre painting, and because the display of such an overt expression as smiling can seem to distort the face of the sitter. This inability of artificial intelligence to reproduce our smiles is teaching us something about the history of art.” Read the rest

Best Practices for Using Maybes and Creating Default Values

See the original posting on DZone Python


You’ve learned that using Maybes allows you to get rid of null pointer exceptions (i.e. “undefined is not a function”). However, now your application fails and gives no indication as to why. Errors would have left a stack trace that could have provided a hint as to where the problem originated, but, clearly here, you don’t have that to rely on. What should you be doing instead?

Null Pointers in Python vs. Ruby, Lua, and JavaScript

Let’s define what we mean by null pointers and how you usually encounter them. Most null pointers you’ll run into are from either accessing a property of an object to show on the screen or calling a method on an object.

How to Use a Vue Pivot Grid UI Component in Your Web App

See the original posting on DZone Python

In this post, we will review the PivotGrid component. Unlike a typical grid, a PivotGrid lets you change the way the data is presented. For example, you may have a data set with inventory items that include the number in stock, category, store, and quarter. You can create a PivotGrid to analyze the total inventory in stock by store and by quarter. Or, you can view the inventory in stock by category and by store. These different perspectives can be viewed in the same grid just by selecting which fields to use for the row and column of the grid. In a regular grid, you could only create one static view. 

Getting Started

We will need the PivotGrid, the PivotConfigurator, and the PivotDataSource components. The PivotGrid displays our summarized data. The PivotConfigurator helps us build the PivotGrid. And the PivotDataSource is an extension of the DataSource component used to bind our data to the PivotGrid and PivotConfigurator. First, we will initialize our project using the Vue webpack-simple template. Then, we will install Kendo UI, a theme, the PivotGrid package, and the DataSource package.

Seven Easy Steps to Install MiniProfiler on an ASP.NET MVC Website

Today, I wanted to add MiniProfiler to an ASP.NET MVC web application (not .NET Core), but unfortunately, the NuGet package doesn’t set up things correctly. The documentation is a bit lacking, and their sample project doesn’t work. So what was supposedly a simple task, took almost a full day of research to finally complete.

Everything is too complicated. Asurion CEO Tony Detter joins Verge editor-in-chief Nilay Patel to discuss simplifying our experience with tech products, the problems with closed ecosystems, and why an insurance company like Asurion got involved with tech support.

Below is a lightly edited excerpt where Detter and Patel discuss what we can do about the “everything is too complicated” problem. You can hear this and more in the latest episode of The Vergecast.

Nilay Patel: Every year around the holidays, I write a post about how everything is too complicated. What happens is that I go home and basically spend the entire time driving around the Midwest to parents’ and families’ houses, and I just listen to my family ask me questions about…

Spotify app update for iPad finally supports multitasking

See the original posting on The Verge

The latest update for the Spotify app on the iPad brings long-awaited support for multitasking features, including Split View (which Apple debuted in 2015) and Slide Over modes. You no longer have to open up a full-screen instance of Spotify to find new music, or switch songs via the limited pull-down menu.

To use the Slide Over feature, add Spotify to your iPad dock, then open it while you’re still using a different app. Spotify will launch as a Slide Over view that sits on top of the app that’s currently running. If you want to use the Split View, tap and drag the top of the Spotify view window to the top of the screen. Your screen will then be split between Spotify and your other app; adjust the size to your taste.

In the sci-fi spoof Iron Sky: The Coming Race, Alien Hitler rides a T-Rex to war

2012’s Iron Sky was an intentionally funny B-movie, lambasting science fiction tropes with the same gusto as Spaceballs or Austin Powers: International Man of Mystery. The film failed to find the cult status it deserves, but it built a following just big and enthusiastic enough to crowdfund a sequel. The result is Iron Sky: The Coming Race, which arrives in theaters and on-demand services on Friday, July 19th.

The original Iron Sky was set in an imagined version of 2018 where astronauts, sent to the dark side of the moon by an unnamed US president bearing a striking resemblance to Sarah Palin (Stephanie Paul), discover Nazis have been hiding there since the end of World War II. What follows is a mashup of Independence Day, Wag the Dog, a…

Amazon Prime Day 2019, the two-day shopping holiday, is wrapping up, and almost everything that was discounted earlier in the week is either sold out or back to its original price. However, not all of the deals are done just yet. We’ve sorted through the remains of Prime Day to see if any deals were left over. There are only a few deals left compared to the hundreds that we originally picked out, but we’ve laid out the best deals below.

You can still get a Samsung Galaxy S10 for as low as $499 at Best Buy, but only if you activate service in-store through Sprint, Verizon, or AT&T. Otherwise, unlocked Samsung Galaxy S10 phones can still be found for around $200 off at Amazon and B&H Photo.
