Just 4 Programmers

Clive Thompson is a longtime contributing writer for the New York Times Magazine and a columnist for Wired and now has a new book out called " Coders ." "Along the way, Coders thoughtfully ponders the morality and politics of code, including its implications for civic life and the economy. Programmers shape our everyday behavior: When they make something easy to do, we do more of it. When they make it hard or impossible, we do less of it." I'm quoted in the book and I talk about how I've struggled with context-switching. Here is TechTarget's decent definition of Context Switching : A context switch is a procedure that a computer's CPU (central processing unit) follows to change from one task (or process) to another while ensuring that the tasks do not conflict. Effective context switching is critical if a computer is to provide user-friendly multitasking. However, human context switching is the procedure we all have to go through to switch...

According to a survey taken of the Scrum Alliance, approximately 70 percent of all groups handling Agile software development believe there are issues present between various internal departments within the company. The fact is, Agile groups work at a much faster pace. In order to mark progress, they use various markets, and in some cases, this puts staff members in direct conflict with each other. The disjunction described above among Agile groups, as well as their peers, is a common mistake in the realm of Agile software development. However, there are a number of other reasons that some Agile projects are unsuccessful as well. You can learn about some of these issues here, and if you have some problems not listed in the article, you can check out DaniWeb software development forum. Knowing what these mistakes are can help you avoid them. Not Using Customer Input There is a large number of groups that don’t pay attention to or use the information that is gathered from their c...

A “key” is one of the most basic and important concepts of the Database Management System (DBMS); the keys helps us work easily with the records and the tables in our database by providing us with the ease of accessing and retrieving the data from the table. A primary key is the first key to be understood as it uniquely identifies the particular record of any table. The primary key and foreign key however, must not be confused with each other as they have a completely different definition as well as usage. Here are the differences between the two. Image Source Difference between Primary Key and Foreign Key S.no. Primary key Foreign key 1 The primary key of a particular table is the attribute which uniquely identifies every record and does not contain any null value. The foreign key of a particular table is simply the primary key of some other table which is used as a reference key in the second table. 2 A primary key attribute in a table can never contain a null value...

Per Wikipedia, "In mathematics , a binary relation ... is transitive if ... element a is related to an element b and b is related to an element c then a is also related to c. " Per Me, if I am cool with you, and you are cool with your friend, then I'm cool with your friend. I've decided this is The Transitive Property of Friendship . As I try to mentor more and more people and help folks Level Up in tech, I'm realizing how important it is to # BeTheLuck for someone else. This is something that YOU can do - volunteer at local schools, forward that resume for your neighbor, give a Warm Intro to a friend of a friend. A lot of one's success can be traced back to hard work and being prepared for opportunities to present themselves, but also to Warm Intros. Often you'll hear about someone who worked hard in school, studied, did well, but then got a job because "their parent knew a person who worked at x." That's something that is hard to re...

AdaFruit makes an adorable tiny little Circuit Python IoT device called the PyPortal that's just about perfect for the kids - and me. It a little dakBoard , if you will - a tiny totally programmable display with Wi-Fi and  lots of possibilities and sensors. Even better, you can just plug it in over USB and edit the code.py file directly on the drive that will appear. When you save code.py the device soft reboots and runs your code. I've been using Visual Studio Code to program Circuit Python and it's become my most favorite IoT experience so far because it's just so easy. The "Developer's Inner Loop" of code, deploy, debug is so fast. As you may know, I use a Dexcom CGM (Continuous Glucose Meter) to manage my Type 1 Diabetes. I feed the data every 5 minutes into an instance of the Nightscout Open Source software hosted in Azure. That gives me a REST API to my own body. I use that REST API to make "glanceable displays" where I - or my family...

Thousands of years ago your ancestors, and myself, were using DOS (or CMD) pressing F7 to get this amazing little ASCII box to pop up to pick commands they'd typed before. When I find myself in cmd.exe I use F7 a lot. Yes, I also speak *nix and Yes, Ctrl-R is amazing and lovely and you're awesome for knowing it and Yes, it works in PowerShell. Here's the tragedy. Ctrl-R for a reverse command search works in PowerShell because of a module called PSReadLine . PSReadLine is basically a part of PowerShell now and does dozens of countless little command line editing improvements. It also - not sure why and I'm still learning - unknowingly blocks the glorious F7 hotkey. If you remove PSReadLine (you can do this safely, it'll just apply to the current session) Remove-Module -Name PSReadLine Why, then you get F7 history with a magical ASCII box back in PowerShell. And as we all know, 4k 3D VR be damned, impress me with ASCII if you want a developer's heart . ...

It's super easy to get started with .NET Core and/or ASP.NET Core with Docker. If you have Docker installed you don't need to install anything to try out .NET Core, of course. To run a little .NET Core console app: docker run --rm mcr.microsoft.com/dotnet/core/samples:dotnetapp And the result: latest: Pulling from dotnet/core/samples Hello from .NET Core! ...SNIP... **Environment** Platform: .NET Core OS: Linux 4.9.125-linuxkit #1 SMP Fri Sep 7 08:20:28 UTC 2018 To run a quick little ASP.NET Core website just: docker run -it --rm -p 8000:80 --name aspnetcore_sample mcr.microsoft.com/dotnet/core/samples:aspnetapp And here it is running on localhost:8000 You can also host ASP.NET Core Images with Docker over HTTPS to with this image, or run ASP.NET Core apps in Windows Containers . Note that Microsoft teams are now publishing container images to the MCR (Microsoft Container Registry) so they can use the Azure CDN and pull faster when they are closer to you glo...
