Font Awesome is a great collection of Free ICONS but customizing them to look pretty for your application has been tedious.  The website has been written using Vue.JS as one of its components.  It is a great example of how Vue.JS can make the user interface look and perform “awesome”.   Give it a test drive at the following link.  I used it today for a handful of Blueish 128 pixel square ICONS for a quick project.

Turn on Network Discovery on Windows Advanced server

Having a problem linking to a Shared resource on a Windows advanced server system?

2017-04-25_16-02-38.jpg

Yea this is a pain the butt.   Some settings are out of wack.

Turn on DNS Client, make it start Automatic Delayed

Turn on SSCP Discovery, make it start Automatic Delayed

2017-04-25_15-58-50

Turn on UPnP Device Host, make it start automatic delayed.

2017-04-25_15-59-22

Set the Network Discovery Firewall rule so it is allowed for Private and Public.

2017-04-25_16-01-24

Now turn network discovery on and it should stay on.

2017-04-25_16-02-99

Now attempt to map to the Shared Drive resource on the Windows AS system.

2017-04-25_16-04-31

If the Shared Drive on the Advanced Server has password protection you will need to login to it using a valid AS user id/password.

2017-04-25_16-04-54

If you’re lucky maybe the mapping will work.  Sometimes the Gods can be cruel.

GMH 033 “Lost” Postbag Adafruit Raspberry Pi 3 Rev B, Light Valve, PI Zero

This is one of the “Lost” videos that was recovered after the transfer to the New Servers It dates back to Feb 2017.  My apologies, It’s a little rough

Raspberry Pi 3 – Model B – ARMv8 with 1G RAM

There are two giant upgrades in the Pi 3. The first is a next generation Quad Core Broadcom BCM2837 64-bit ARMv8 processor, making the processor speed increase from 900 MHz on the Pi 2 to up to 1.2GHz on the Pi 3.

The second giant upgrade (and this is the one we’re personally most excited about) is the addition of a BCM43143 WiFi chip BUILT-IN to your Raspberry Pi. No more pesky WiFi adapters – this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution (BLE support is still in the works, software-wise)

Lastly, there’s an upgraded switched power source that goes up to 2.5 Amps instead of just 2 Amps – allowing your Pi to power even more powerful devices over USB ports.

Liquid Crystal Light Valve – LCD Controllable Black-out Panel

What do you get when you power a layer of liquid crystal material sandwiched between two sheets of glass? A Liquid Crystal Light Valve (a.k.a a LCD Controllable Black-out Panel)! They’re often used for electric welding helmets because they can protect the welder’s eyes from the bright sparks. Or – if you aren’t a welder – they can be used to provide a “reveal” effect for your project, as you can control the opaqueness of the LCD.

Rasberry Pi Zero W

More specifically, this giant upgrade is the addition of a BCM43143 WiFi chip BUILT-IN to your Raspberry Pi Zero – just like the Pi 3! No more pesky WiFi adapters – this Pi is WiFi ready. There’s also Bluetooth Low Energy (BLE) on board making the Pi an excellent IoT solution (BLE support is still in the works, software-wise).

Better tools for debugging Node.js

Debugging – the process of finding and fixing defects in software – can be a challenging task to do in all languages. Node.js is no exception. Luckily, the tooling for finding these issues improved a lot in the past period. Let’s take a look at what options you have to find and fix bugs in…

I am at the level with Node.JS that I no longer “Suck at it” but I am still learning every time I use it.  One of the areas I struggled with was debugging, which was much different and difficult than my .NET and PHP days.  It seems like open source meant that you were on your own for debugging.

Special thanks to Gergely for his article on just the topic of Node.js debugging.

pino.pngOne of the takeaways in the article is Pino is an extremely fast Node.js logger, inspired by bunyan. In many cases, pino is over 6x faster than alternatives like bunyan or winston
I had tried Winston as it was recommended by one of my programmer gods.  I was not worthy because I couldn’t understand it.  I have high hopes for Pino.

I use Microsoft VS Code editor as my editor and my IDE for almost everything including PowerShell, Bash, JavaScript, SQL, Node.js, ADCIIDoctor, and more.  I was glad to see a section in this article on how to better use MS Code with Node.js

Presto, Magico open source distributed SQL Engine

2017-04-25_11-23-16In today’s blog, I will be introducing you to a new open-source distributed SQL query engine, Presto. It is designed for running SQL queries over Big Data (petabytes of data). It was designed by the people at Facebook. Quoting its formal definition:

“Presto is an open-source distributed SQL query engine for running interactive analytic queries against data sources of all sizes ranging from gigabytes to petabytes.”

Th folks at Facebook are at it again.   They build a SQL engine especially for analytical work, this is not an online transaction processing (OLTP) engine.  It’s an engine for ad-hoc queries across SQL/NoSQL databases distributed all over the place.

They use connectors for MySQL, Hadoop/Hive, MongoDB, Postgres and more.  Missing are some of standards like Microsoft SQL and Teradata.  However, this won’t be the story for long.

Presto is in its open source newness but you should take a look at the documentation to really appreciate the power of this new thing.

Scrum is about less complexity by doing less

download

Many of Scrum propagators (mainly trainers and consultants who are “selling” Scrum) claim that thanks to them, Scrum Teams became hyper-productive. They claim that teams are able to deliver much more (up to 600%?) functionalities in the same amount of time. Scrum increases a team’s productivity – that can be a nice marketing slogan. But…

One of the things I preach about Agile is one of the base tenets of the Agile manifesto.

Working software over comprehensive documentation.

Precise comprehensice  documentation will not by itself make software product better.  The document is usually inaccurate within a couple of weeks after it has been delivered.  Often the document is used as a “Contract” to help define who to “Blame” when something isn’t “Correct”.

So you’re building something that looses it value quickly and can be used as a weapon later on against you.  Customer collaboration early on in a project and interacting with folks who are going to use the software will do more than that document.  Less is more.

Start with a small snowball, roll it down the hill and watch what happens.  If it falls apart just start over, it was a small snowball it should not take that much effort.  If the snowball got bigger than take it back up the hill and do it over.   Eventually, you will have a huge snowball that becomes the first deliverable.

I like to use Active Hi-Resolution Prototypes with the ability for reviewers to collaborate directly with the prototype and provide feedback.  The feedback and suggestions help to become a critical part of the “Document”.
