Docker Basics: How to Use Dockerfiles – The New Stack
Saved by uncleflo on January 16th, 2022.
By using a Docker image, it is not only possible to deploy one container after another, it’s quite easy. Once you’ve pulled the image from a registry (such as Docker Hub), each container can then be deployed with a single docker command. But what happens when you find yourself having to deploy numerous containers (each for a different purpose) from the same image? All of a sudden the management of those containers can get a bit cumbersome. Say, for example, you pull down the latest Ubuntu image for development. Before you can develop with that container, there are a number of modifications you want to make to the image (such as upgrading software and adding the necessary development packages for the job at hand). For this, you could manually edit each image as needed (creating a new image for each necessary variation on the theme), or you could construct a Dockerfile for each variation. Once you have your Dockerfile constructed, you can quickly build the same image over and over, without having to take the time to do it manually. Carefully crafted Dockerfiles can save you considerable time and effort.

Can Windows tell me what is using my USB drive? - Super User
Saved by uncleflo on January 16th, 2022.
Connect and share knowledge within a single location that is structured and easy to search. Being the good citizen I am, I left-click on the "Safely Remove Hardware" icon in my taskbar, and select my USB drive to dismount. Then I get the message: Windows can't stop your Generic volume device because it is in use. Close any programs or windows that might be using the device, and then try again later. Of course, being the Operating System, it knows exactly what applications are using my device. So why won't it tell me? Or is there a way that I can find out?

The Stoch RSI : A Powerful Signal for Stock Pickers! - PLblog
Saved by uncleflo on May 15th, 2021.
In a previous piece, https://www.plindia.com/blog/stochastic-oscillators-defined/, we had talked about how the Stochastic Oscillator can be a simple to understand yet powerful tool to pick stocks – just like its other cousin Williams % R. One often uses this indicator with something like RSI to gauge momentum and can give powerful insights into emerging trends What if, therefore, there was a tool that captured it all in one single indicator! Introducing Stoch RSI! The Stochastic RSI indicator, developed by Tushard Chande and Stanley Kroll, is an oscillator that uses RSI values, instead of price values, as inputs in the Stochastic formula. The indicator measures where the RSI’s current value is relative to its high/low range for the specified period – thus becoming an indicator of indicators!

How are you guys handling QA environments on AWS? : aws
Saved by uncleflo on July 11th, 2019.
News, articles and tools covering Amazon Web Services (AWS), including S3, EC2, SQS, RDS, DynamoDB, IAM, CloudFormation, Route 53, CloudFront, Lambda, VPC, Cloudwatch, Glacier and more. Just a curiosity. At this point I've done: single staging environment for small teams, and that obviously doesn't work well beyond a couple; one off EC2 instances that just use docker to make a mini-replicated environment; cloudformation to spin up an entire, and yet smaller, version of our production; ngrok and just having our QA test directly. The area I'm interested to see how people are handling it is with respect to data. Are you replicating the full DB? Just using in memory and some seed data? Additionally, for those of you that have this (or have had one in the past), how did you guys set it up to be "pleasurable" to work with? By that I mean it not being some long winding rube goldberg machine that almost defeats the purpose of having a CI.

PDF - Four or more layer PCB design for beginners using EAGLE
Saved by uncleflo on June 23rd, 2019.
With microcontrollers and other Integrated Circuit (IC)’s getting smaller and smaller Printed Circuit Board (PCB) design gets more and more difficult. 2 layer PCB design is getting common for small companies and hobbyists but 4 layer or more is a bit daring for those used to 2 layers. When designing a circuit with a Ball Grid Array (BGA) that has 100 or more pins a 4 layer circuit board is necessary, but more layers can make designing easier. With prices of 4 layer boards getting lower it can be a better idea to route a board thats hard to do in 2 layers in 4 layers as it can save a lot of time. This document will explain the basics of routing PCBs with 4 or more layers with Cadsoft Eagle.

users - How do daemons work? - Unix & Linux Stack Exchange
Saved by uncleflo on January 4th, 2019.
If a user wants to execute a command, he has to first log in into a system. But some users in the system have /bin/false or /sbin/nologin set as a default shell in the /etc/password file. If I change /bin/bash to /bin/false in case of my user, I won't be able to log in into the system, so I also won't be able to run commands. But the shellless users do it anyway: How can a user without a shell execute a command? In POSIX, every running process has three User IDs (UIDs) associated with it; the real UID, which identifies the user who launched the process, the effective UID, which is used to determine what resources the process can access, and the saved Set-User-ID (SUID), which is the effective UID the process had when it started (at the point of the last exec() call). Of these, the effective UID is the most significant, since it is the one used when determining access control decisions regarding the process.

Building and calibrating a stereo camera with OpenCV (<50€) | Stackable
Saved by uncleflo on February 8th, 2015.
I’ve decided to try my hand at 3D reconstruction using a stereo camera. There are a few good sets of instructions on how to get started with this. I decided to take some heavy inspiration from them and will be citing them as I go in the post. I ended up not following any of the instructions precisely because I have a few goals that are not fulfilled by any single source that I could find

Set Java 1.6 default over 1.7 in Ubuntu Linux - Stack Overflow
Saved by uncleflo on September 15th, 2014.
Here is the output to some inspection that I did. With that in mind, how do I go about changing the default to 1.6 so that when I execute java -version, it tells me 1.6? I am on Fedora but I hope that alternatives works the same way on Ubuntu. You need to run update-alternatives --config java (on Fedora just alternatives --config java) to see what options you have. Then type the number of the JDK you want to use and press enter.

esc - Controlling small brushless dc motors? - Electrical Engineering Stack Exchange
Saved by uncleflo on July 16th, 2014.
I'm designing an ESC with a small microcontroller running at 3.3V. The BLDC motors I have chosen are extremely small, and run best at 3.7V. I have the power supply for both of these (3.7V is VBATT, 3.3V is obtained using a buck converter). They are 3 phase, and the controller needs to be sensorless. I would like to measure RPM and current usage as well if it doesn't mean I will have an overly complicated design. All the docs I have found are great for higher voltages, and ridiculous currents (I will max out at ~5Amps at 3.7V, I don't necessarily need to design a 100V, 300A ESC). Questions I have: Is there a reference design I can follow somewhere around the net? What kind of protection circuitry should I use? How simple can I go? Are there any ICs that will simplify the circuit even further? Any other recommendations/tips/pointers?

git - gitosis vs gitolite? - Stack Overflow
Saved by uncleflo on July 4th, 2013.
I am looking for installing a git server to share projects with my team. I don't want to create a user account on the server with SSH access for each developer that needs a git access. It seems there is two concurrent solutions that cover this issue : gitosis & gitolite. I could not find any comparison between both solutions. What are the main differences between them? Are there other similar solution?

How do I use z-index in Flex 3? - ActionScript.org Forums
Saved by uncleflo on September 6th, 2011.
Ok, apparently setChildIndex() only sets the display index number of the item in the container (item #1 to display, item #2 to display, etc.), but doesn't have anything to do with z-index (i.e., layering items on top of one another)? This is exactly what it does!
