Historical achievements, such as the establishment of the Women’s National Hockey League (NWHL) and the Premier Hockey Federation (PHF), mark significant milestones in the journey towards equality. These leagues have provided female athletes with platforms to showcase their skills, while also inspiring future generations of players.

Women like Cammi Granato and Hayley Wickenheiser have not only excelled on the ice but also emerged as influential role models, inspiring young athletes to pursue their dreams.

For instance, local leagues often highlight historical achievements of female athletes, showcasing role models who inspire young girls.

Moreover, advocacy and support for women in leadership positions within sports organizations can lead to significant league developments. Community events that celebrate female athletes not only raise awareness but also encourage participation. This creates an ecosystem where young women are motivated to pursue their passions.

Ultimately, these efforts help in establishing a culture where women are recognized for their contributions, paving the way for equitable opportunities in the sports arena. By investing in grassroots initiatives, we ensure that future generations will thrive and continue to break barriers.

Recover gigs of storage with this simple hack

I recovered 30 gigs of storage on my MBP (MacBook Pro) with this simple hack of converting my PNGs to JPEGs. Here’s how.

If you own a Mac or an iPhone, you’ll notice both devices save “screenshots” with a PNG extension. Portable Network Graphics (.png), an image file format is uses lossless compression to save your images. You maybe thinking this lossless compression is the best format but the reality is JPEG, a lossy compression, is just as good at retaining image quality at a MASSIVE fraction of the size of a PNG.

Image sizes really matter when your device runs 1080p+ resolutions (most modern Macs) or new OLED iPhones. A full size (no crop) screenshot on my MBP with a resolution of 2080×1080 yields a 7MB (7168kb) image. A JPEG equivalent is 500kb. That’s ~14x smaller. If you are like me and take screenshots as reminders or todos (GTD baby!) then you’ll be chewing through storage fast.

100 of these PNGs and you’ll be reaching the 1Gb territory.

With storage being dirt cheap who cares right? Not so. Laptops with external drives are annoying and iPhones do not have extension cards. Furthermore, data transfer is a burden consider upload speeds are always conveniently ignored yet important if you are backing up to the cloud. And let’s face it, who’s got time to sit around waiting when the same lot of photos with identical quality (assuming you aren’t blowing them up on a wall) can be backed up to your Dropbox cloud storage 14x faster. GTD baby!

Did I mention this will also speed up your Spotlight searching, indexing, extend your SSD life and open those images faster.

Convert PNGs to JPEGS

PNG are uncompressed images from things mainly like Screenshots on your Mac or iPhone. They don’t need to be PNG unless you really are picky about the quality of text sharpness. ie. Under JPEG text becomes a tad more blurry since compression reuses surrounding pixels to make image smaller.

Overall, the chance of you retaining PNGs is low unless you do a lot of photo editing and need that pixel level detail especially for font/text clarity.

[1] Identify Opportunities

Run a scan to identify where the opportunities (PNGs) are located on your drive.

$ find . -type f -iname '*.png' | wc -l

find . -type f finds all files ( -type f ) in this ( . ) directory and in all sub directories, the filenames are then printed to standard out one per line.

This is then piped | into wc (word count) the -l option tells wc to only count lines of its input.

If you only want files directly under this directory and not to search recursively through subdirectories, you could add the -maxdepth flag:

$ find some_directory -maxdepth 1 -type f | wc -l

The key to that case-insensitive search is the use of the -iname option, which is only one character different from the -name option. The -iname option is what makes the search case-insensitive.

[2] Convert

Create JEPG versions of the PNGS and remove old PNGs. There is no need to keep the old PNGs. They are the ones that take up all the space.

Run this on a small subset of your PNGs to make sure you are happy with the resulting JPEG.

$ mogrify -format jpg *.png && rm *.png

Who really owns your Bose QC35 headphones?

I was excited to finally get my hands on the new Bose QC35 II because noise simply annoys me more than the average bear. The beautiful world we live in today is very noisy, from cars to traffic lights to photocopiers to background chatter, and it’s something some of us have learnt to live with while others suffer from the disruption. I’m in the latter crew. Until that it, a $300 Bose QC35 II became my friends, even if it was for a short period of time. If you’re showcasing products like this online, a professional product video editing service can help highlight their features in a more engaging way.

During this short period of time they were amazing. The ANC (Active Noise Cancelling) was superb! I was so excited I started showcasing (marketing for Bose) to all my software engineers and entrepreneurs, who like me seek silence to do their focused work, how their lives will change. I also sold my wife on these as a solution for plane travel. Noise inside planes reaches 80db, the sound of a vacuum cleaner near your ears on a trip from San Francisco to Sydney has shown over time to damage ear drums.

That is until I upgraded to firmware 4.5.2.

Enter the Firmware

You see, the Bose QC35 II has a computer inside which uses the multiple microphones places strategically to listen to incoming noise and cancel out the sound waves. This is orchestrated by a small onboard computer (think Arduino, like those from kunkune.co.uk) running custom Bose software to run and manage the hardware. Hence ACN. Software has bugs. Even production versions. Thus is the nature (complexity) of the beast. And manufacturers will send updates over the internet to patch things up.

I have no idea why I installed the firmware update since the headphones were working flawlessly. I’m sure it was from habit; an expectation of better things to come from an update. Just like when I update my iPhone or MBP I get better performance and maybe few new bells and whistles (features).

Sound Quality Degradation

After the update, the noise cancelling quality of my QC35 II was degraded. I sat there in the library hearing the photocopier and background chatter. Something I could never hear before. WTF! I tried the 2 ACN noise levels (high and low) and both were indistinguishable.

There was something wrong with the v4.5.2 firmware update.

Source: Bose Update RUINS Noise Cancelling??? (TESTED) — https://www.youtube.com/watch?v=yyC9QStmzcA&feature=youtu.be

Whether intentional or not, one has to question whether Bose took the $9 an hour engineer outsource route (Boeing is famous for doing so with their 737 MAX MCAS) because something like this surely could not happen if they owned the whole release process and had QA. However the timing of these degrading version updates coincides with the more expensive Bose Noise Cancelling Headphones 700 release. Coincidence or not I’ll leave this to the conspiracy experts to debate.

Next Steps

  1. Downgrade downgrade your Bose QuietComfort 35 II from 4.5.2 to 3.1.8. Yes it’s a tad complex but unfortunately Bose doesn’t support this, nor do they even explain what each version contains, so do this at your own risk.
  2. Send it back to Bose for replacement/repairs; but good luck. The customers who did say the returned units were just as bad.
  3. Leave your views/complaints on the Bose Community website to hopefully make them acknowledge this and fix it for good. Go here: https://community.bose.com/t5/Around-On-Ear-Headphones/Bose-QC-35-ii-firmware-4-5-2/td-p/213820

So who really owns your Bose QC35 headphones?

Bose.

They are the puppet master here. Controlling at will the quality of the headphones you paid them handsomely for.

Commanding a premium for average quality sound gear with what used to be amazing ACN, then manipulating the quality of their ACN moat through ghost version updates to prop new cheaper build products (*cough* Bose 700) by degrading previous generation units.

If you own the QC35 please let me know how your experience has been so far.

Dockerizing a web app, using Docker Compose for orchestrating multi-container infrastructure (part 1 of 3)

 

This is a GUEST BLOG POST by Andrew Bakonski

Head of International Engineering @ Veryfi.com

Andrew heads up International Engineering efforts at Veryfi supporting Veryfi’s Hybrid Infrastructure on AWS & Azure making sure the lights stay on.

Andrew’s LinkedIn: https://www.linkedin.com/in/andrew-bakonski/

A couple months ago we decided to move Veryfi’s Python-based web app onto Microsoft Azure. The process was complicated and involved several stages. First I had to Dockerize the app, then move it into a Docker Swarm setup, and finally set up a CI/CD pipeline using Jenkins and BitBucket. Most of this was new to me, so the learning curve was steep. I had limited experience with Python and knew of Docker and Jenkins, but had yet to dive into the deep end. After completing the task, I thought I could share my research and process with the Veryfi community.

I’ve compiled a three-part series that will cover these topics:

  1. Dockerizing a web app, using Docker Compose for orchestrating multi-container infrastructure
  2. Deploying to Docker Swarm on Microsoft Azure
  3. CI/CD using BitBucket, Jenkins, Azure Container Registry

This is the first post in the series.

I won’t go into a full blown explanation of Docker – there are plenty of articles online that answer that question, and a good place to start is here. One brief (and incomplete) description is that Docker creates something similar to Virtual Machines, only that Docker containers run on the host machine’s OS, rather than on a VM. Each Docker container should ideally contain one service and an application can comprise of multiple containers. With this approach, individual containers (services) can be easily swapped out or scaled out, independently of others. For example, our main web app currently runs on 3 instances of the main Python app container, and they all speak to one single Redis container.

Dockerizing an app

Note: the example included in this section can be found in this GitHub repo: https://github.com/abakonski/docker-flask
The example here is a minimal, “Hello World” app.

Docker containers are defined by Docker images, which are essentially templates for the environment that a container will run in, as well as the service(s) that will be running within them. A Docker image is defined by a Dockerfile, which outlines what gets installed, how it’s configured etc. This file always first defines the base image that will be used.

Docker images comprise multiple layers. For example, our web app image is based on the “python:3.6” image (https://github.com/docker-library/python/blob/d3c5f47b788adb96e69477dadfb0baca1d97f764/3.6/jessie/Dockerfile). This Python image is based on several layers of images containing various Debian Jessie build dependencies, which are ultimately based on a standard Debian Jessie image. It’s also possible to base a Docker image on “scratch” – an empty image that is the very top-level base image of all other Docker images, which allows for a completely customizable image, from OS to the services and any other software.

In addition to defining the base image, the Dockerfile also defines things like:

  • Environment variables
  • Package/dependency install steps
  • Port configuration
  • Environment set up, including copying application code to the image and any required file system changes
  • A command to start the service that will run for the duration of the Docker container’s life

This is an example Dockerfile:

FROM python:3.6

# Set up environment variables
ENV NGINX_VERSION '1.10.3-1+deb9u1'

# Install dependencies
RUN apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 \
    && echo "deb http://httpredir.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list \
    && echo "deb-src http://httpredir.debian.org/debian/ stretch main contrib non-free" >> /etc/apt/sources.list \
    && apt-get update -y \
    && apt-get install -y -t stretch openssl nginx-extras=${NGINX_VERSION} \
    && apt-get install -y nano supervisor \
    && rm -rf /var/lib/apt/lists/*


# Expose ports
EXPOSE 80

# Forward request and error logs to Docker log collector
RUN ln -sf /dev/stdout /var/log/nginx/access.log \
    && ln -sf /dev/stderr /var/log/nginx/error.log

# Make NGINX run on the foreground
RUN if ! grep --quiet "daemon off;" /etc/nginx/nginx.conf ; then echo "daemon off;" >> /etc/nginx/nginx.conf; fi;

# Remove default configuration from Nginx
RUN rm -f /etc/nginx/conf.d/default.conf \
    && rm -rf /etc/nginx/sites-available/* \
    && rm -rf /etc/nginx/sites-enabled/*

# Copy the modified Nginx conf
COPY /conf/nginx.conf /etc/nginx/conf.d/

# Custom Supervisord config
COPY /conf/supervisord.conf /etc/supervisor/conf.d/supervisord.conf

# COPY requirements.txt and RUN pip install BEFORE adding the rest of your code, this will cause Docker's caching mechanism
# to prevent re-installinig all of your dependencies when you change a line or two in your app
COPY /app/requirements.txt /home/docker/code/app/
RUN pip3 install -r /home/docker/code/app/requirements.txt

# Copy app code to image
COPY /app /app
WORKDIR /app

# Copy the base uWSGI ini file to enable default dynamic uwsgi process number
COPY /app/uwsgi.ini /etc/uwsgi/
RUN mkdir -p /var/log/uwsgi


CMD ["/usr/bin/supervisord"]

Here’s a cheat sheet of the commands used in the above example:

  • FROM – this appears at the top of all Dockerfiles and defines the image that this new Docker image will be based on. This could be a public image (see https://hub.docker.com/) or a local, custom image
  • ENV – this command sets environment variables that are available within the context of the Docker container
  • EXPOSE – this opens ports into the Docker container so traffic can be sent into them. These will still need to be listened to from within the container, (i.e. NginX could be configured to listen to port 80). Without this EXPOSE command, no traffic from outside the container will be able to get through on those ports
  • RUN – this command will run shell commands inside the container (when the image is being built)
  • COPY – this copies files from the host machine to the container
  • CMD – this is the command that will execute on container launch and will dictate the life of the container. If it’s a service, such as NginX, the container will continue to run for as long as NginX is up. If it’s a quick command (i.e. “echo ‘Hello world'”), then the container will stop running as soon as the command has executed and exited

The Docker image resulting from the above Dockerfile will be based on the Python 3.6 image and contain NginX and a copy of the app code. The Python dependencies are all listed in requirements.txt and are installed as part of the process. NginX, uWSGI and supervisord are all configured as part of this process as well.

This setup breaks the rule of thumb for the “ideal” way of using Docker, in that one container runs more than one service (i.e. NginX and uWSGI). It was a case-specific decision to keep things simple. Of course, there could be a separate container running just NginX and one running uWSGI, but for the time being, I’ve left the two in one container.

These services are both run and managed with the help of supervisord. Here’s the supervisord config file that ensures NginX and uWSGI are both running:

[supervisord]
nodaemon=true

[program:uwsgi]
# Run uWSGI with custom ini file
command=/usr/local/bin/uwsgi --ini /etc/uwsgi/uwsgi.ini
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

[program:nginx]
# NginX will use a custom conf file (ref: Dockerfile)
command=/usr/sbin/nginx
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

Launching a Docker container

I’m not including the instructions on installing Docker in this post (a good place to get started is here)

With the above project set up and Docker installed, the next step is to actually launch a Docker container based on the above image definition.

Frist, the Docker image must be built. In this example, I’ll tag (name) the image as “myapp”. In whatever terminal/shell is available on the machine you’re using (I’m running the Mac terminal), run the following command:

$ docker build -t myapp .

Next, run a container based on the above image using one of the following commands:

# run Docker container in interactive terminal mode - this will print logs to the terminal stdout, hitting command+C (or Ctrl+C etc) will kill the container
$ docker run -ti -p 80:80 myapp

# run Docker container quietly in detached/background mode - the container will need to be killed with the "docker kill" command (see next code block below)
$ docker run -d -p 80:80 myapp

The above commands will direct traffic to port 80 on the host machine to the Docker container’s port 80. The Python app should now be accessible on port 80 on localhost (i.e. open http://localhost/ in a browser on the host machine).

Here are some helpful commands to see what’s going on with the Docker container and perform any required troubleshooting:

# list running Docker containers
$ docker ps


# show logs for a specific container
$ docker logs [container ID]


# connect to a Docker container's bash terminal
$ docker exec -it [container ID] bash


# stop a running container
$ docker kill [container ID]


# remove a container
$ docker rm [container ID]


# get a list of available Docker commands
$ docker --help

Docker Compose

Note: the example included in this section is contained in this GitHub repo: https://github.com/abakonski/docker-compose-flask
As above, the example here is minimal.

The above project is a good start, but it’s a very limited example of what Docker can do. The next step in setting up a microservice infrastructure is through the use of Docker Compose. Typically, most apps will comprise multiple services that interact with each other. Docker Compose is a pretty simple way of orchestrating exactly that. The concept is that you describe the environment in a YAML file (usually named docker-compose.yml) and launch the entire environment with just one or two commands.

This YAML file describes things like:

  • The containers that need to run (i.e. the various services)
  • The various storage mounts and the containers that have access to them – this makes it possible for various services to have shared access to files and folders
  • The various network connections over which containers can communicate with each other
  • Other configuration parameters that will allow containers to work together
version: '3'

services:
  redis:
    image: "redis:alpine"
    ports:
      - "6379:6379"
    networks:
      - mynet

  web:
    build: .
    image: myapp:latest
    ports:
      - "80:80"
    networks:
      - mynet

networks:
  mynet:

The above YAML file defines two Docker images that our containers will be based on, and one network that both containers will be connected to so that they can “talk” to each other.

In this example, the first container will be created based on the public “redis:alpine” image. This is a generic image that runs a Redis server. The “ports” setting is used to open a port on the container and map it to a host port. The syntax for ports is “HOST:CONTAINER”. In this example we forward the host port 6379 to the same port in the container. Lastly, we tell Docker compose to put the Redis container on the “mynet” network, which is defined at the bottom of the file.

The second container defined will be based on a custom local image, namely the one that’s outlined in the first section of this article. The “build” setting here simply tells Docker Compose to build the Dockerfile that is sitting in the same directory as the YAML file (./Dockerfile) and tag that image with the value of “image” – in this case “myapp:latest”. The “web” container is also going to run on the “mynet” network, so it will be able to communicate with the Redis container and the Redis service running within it.

Finally, there is a definition for the “mynet” network at the bottom of the YAML file. This is set up with the default configuration.

This is a very basic setup, just to get a basic example up and running. There is a ton of info on Docker Compose YAML files here.

Once the docker-compose.yml file is ready, build it (in this case only the “web” project will actually be built, as the “redis” image will just be pulled from the public Docker hub repo). Then bring up the containers and network:

# build all respective images
$ docker-compose build

# create containers, network, etc
$ docker-compose up

# as above, but in detached mode
$ docker-compose up -d

Refer to the Docker commands earlier in this article for managing the containers created by Docker Compose. When in doubt, use the “–help” argument, as in:

# general Docker command listing and help
$ docker --help

# Docker network help
$ docker network --help

# Help with specific Docker commands
$ docker <command> --help

# Docker Compose help
$ docker-compose --help

So there you have it – a “Hello World” example of Docker and Docker Compose.

Just remember that this is a starting point. Anyone diving into Docker for the first time will find themselves sifting through the official Docker docs and StackOverflow forums etc, but hopefully this post is a useful intro. Stay tuned for my follow-up posts that will cover deploying containers into Docker Swarm on Azure and then setting up a full pipeline into Docker Swarm using Jenkins and BitBucket.

Linux Server Security Checklist

Had this sitting around in my Google Docs for some time. Good idea to share these Linux security tips to help others secure their boxes. So here it is peeps.

Linux security – paranoid check-list

  1. For direct access to your box, only use ssh. SSH is the most secure standard for both authentication (both host and user) and data protection (everything strongly encrypted, end-to-end).
  2. Enable key-pairs as the only way to access your box. Don’t allow passworded logins. Most passwords are too short and sit (even if in hashed form) on many databases: your bank, your favorite retailer etc. My guide on SSH setup will guide you through this by setting in sshd_config.
    PasswordAuthentication no
  3. Run ssh on a high port. The reason is that a lot of security scanners will only scan the standard known-service ports or the lower range (1-1024 are privileged ports that only superuser can bind/listen to, so they are more attractive to hackers) So running on 43256 (there are 2^16 =~ 65k ports) is much safer. Using an IP Address Lookup Tool can also add another layer of security.
  4. In the firewall rules, limit access to your (and your customers) IP blocks, i.e. instead of 0.0.0.0/0 (all the internet) allow only from (say) 12.167.110.0/24 (specific block)
  5. Control the users who are allowed entry to your server.
    sudo nano /etc/ssh/sshd_config
    AllowUsers username1 username2
  6. Never ever permit root logins:
    sudo nano /etc/ssh/sshd_config
    PermitRootLogin no
  7. All administrative stuff is done as a known user (accountability) which used ‘sudo’ after you have authenticated in via SSH.
  8. Use a second layer firewall (software firewall) in case the first goes down. On Linux you can use iptables with Gufw, one of the easiest firewall in the world, to manage the iptables.
    sudo apt-get install gufw
  9. Run logcheck, a periodic system log scanning that will email you any unusual event. logcheck comes with a very large rule-set of what can be safely ignored so it only emails when something really new and different shows up in the logs.
    sudo apt-get install logcheck
    sudo nano /etc/logcheck/logcheck.conf
    # Add your email to SENDMAILTO
    sudo -u logcheck logcheck # run a test
  10. Run tripwire, a service that scans all the executables on the system, and alerts when a signature has changed (i.e. the file has been replaced). There is also a good post here on Setting up Tripwire in Ubuntu 11.10 – Intrusion Detection System.
    sudo apt-get install tripwire

And that’s a wrap! Are there any others you would recommend?

How to: SSH secure key authentication on Ubuntu

Open SSH is the most widely used SSH server on Linux. Using SSH, one can connect to a remote host and gain a shell access on it in a secure manner as all traffic is encrypted.

A neat feature of open SSH is to authenticate a user using a public/private key pair to log into the remote host. By doing so, you won’t be prompted for the remote user’s password when gaining access to a protected server. Of course you have to hold the key for this to work. By using key based authentication and by disabling the standard user/password authentication, we reduce the risk of having someone gaining access to our machine/s. For more info on data access management, visit sites like https://cyral.com/data-access-governance/. And if you need comprehensive visibility to enable compliance and secure data sharing, you might want to read more here to learn more. Moreover, if you need Cyber Security Solutions in charge of data protection of your company, you may look for a time-limited privileged access management system that evaluates each access request. You may click here to find out more.

Implement NIST Cybersecurity Framework in 3 weeks using CyberArrow. CyberArrow is a technology first solution that automates the evidence collection for NIST CSF controls. CyberArrow can be used by any type of organization.

So if you are not using SSH with public/private key pair, here is how to get this rolling. If you are using AWS (Amazon Web Services) you would have been forced to use this method. This is great! The instructions below will teach you a bit about this and provide insight into setting this up on your dev VM or a server which doesn’t have this level of security turned on.

Useful commands to note

Accessing server using key

ssh -i ./Security/PRIVATEKEY USERNAME@SERVER -p PORT

Example:

ssh -i ./Security/aws/myname_rsa root@127.0.0.1 -p 22345

Restart SSH server

sudo /etc/init.d/ssh restart

Install & Setup SSH Security Access

Note: This section is for admins only.

On your Server (remote host) Locally on your box
1. Install SSHOnly if not already installed.
sudo apt-get install openssh-server
sudo apt-get install openssh-client

Make sure you change your server (and firewall is present) it to listen on port 22345 (or similar port of your liking in the high range) vs the standard unsecure 22.

Via Shell

sudo nano /etc/ssh/sshd_config
sudo /etc/init.d/ssh restart

OR

In Webmin >SSH Server > Networking > Listen on port = 22345

How to install Webmin instructions are here: http://www.theroadtosiliconvalley.com/technology/building-ubuntu-lamp-web-server-vm/

On your Server (remote host) Locally on your box
2. Create a public/private key pair.
ssh-keygen -t rsa

This will generate the keys using a RSA authentication identity of the user. Why RSA instead of DSA? RSA is 2048 bit key vs DSA 1024 bit key restricted. Read here: http://security.stackexchange.com/questions/5096/rsa-vs-dsa-for-ssh-authentication-keys

By default the public key is saved in the file:~/.ssh/id_rsa.pub,
while private key is:~/.ssh/id_rsaeg.

3. Copy the generated myname_rsa.pub file to the remote host. Use SFTP and from:
/Users/name/.ssh/myname_rsa.pub drop it into remote host path:
/root/.ssh/myname_rsa.pubNote: If that folder doesn’t exist then create it.
sudo mkdir /root/.ssh/
On your Server (remote host) Locally on your box
4. SSH into remote host and append it to ~/.ssh/authorized_keys by entering:
cat /root/.ssh/myname_rsa.pub >> ~/.ssh/authorized_keys
rm /root/.ssh/myname_rsa.pub
4.1. Check the permissions on the authorized_keys file.Only the authenticated user should have read and write permissions. If the permissions are not correct change them by:
chmod 600 ~/.ssh/authorized_keys
5. Enable SSH public/private key pair access.
sudo nano /etc/ssh/sshd_config

Make sure you have the following:RSAAuthentication yesPubkeyAuthentication yesSave when exiting.

6. Reload new configuration.
/etc/init.d/ssh reload (or)
service ssh reload
On your Server (remote host) Locally on your box
7. Protect your private key file.Locally on your machine assuming you moved the private key file to folder ./Security/
chmod 0600 ./Security/myname_rsa
8. Test your new setup.Login to your remote host from your machine:
ssh -i ./Security/KEYFILE USERNAME@SERVER -p PORTNO

where ./Security/KEYFILE is the location of your private key file.eg.

ssh -i ./Security/myname_rsa root@1.1.1.1 -p 22345

You should be granted access immediately without password requirements.

On your Server (remote host) Locally on your box
9. Disable authentication by password.
sudo nano /etc/ssh/sshd_config

Make sure you have the following:

ChallengeResponseAuthentication no 
PasswordAuthentication no
UsePAM no

Save when exiting.

10. Reload new configuration.
/etc/init.d/ssh reload (or)
service ssh reload
On your Server (remote host) Locally on your box
11. Test #2 your new setupLogin to your remote host from your machine:
ssh -i ./Security/KEYFILE USERNAME@SERVER -p PORTNO

where ./Security/KEYFILE is the location of your private key file.eg.

ssh -i ./Security/myname_rsa root@1.1.1.1 -p 22345

You should be granted access immediately without password requirements.Also test using the old method which should prohibit access.

ssh root@1.1.1.1 -p 22345

Should yield: Permission denied (publickey).
Server is now protected against brute-force attacks.

Finally make sure you adjust your development tools so they tool can gain access to your secured server.

Tools

Your choice of tools my vary but the process is very similar. The following are my most used tools and how to tweak them to allow SSH key entry to my secured server.

FileZilla – SFTP

To enable FileZilla to access the server under the new configuration do this:

  1. FileZilla > Preferences…
  2. Settings window opens. Select “Connection > SFTP” (left hand navigation).
  3. In the right pane, click on “Add keyfile…”. Navigate to your private keyfile and click on it to add.
  4. You may be asked by FileZilla to “Convert keyfile” to a supported FileZilla format. This is fine and just click “Yes”. Save the output file to the same location as your private key file.
  5. Click OK on the Settings file to save final changes.

SublimeText2 – IDE

To enable SublimeText2 to access the server under the new configuration do this.

In your solutions sftp-settings.json configuration file enable key file access like this:

"ssh_key_file": "~/.ssh/id_rsa",

Example:

"ssh_key_file": "~/Security/myname_rsa",

And that’s it. Happy development!

Outsourcing software development: pros and cons

Outsourcing part of software engineering is not for everyone. Outsourcing requires a lot of micromanagement and software engineering background to make sure that what you ask for is what you get.

What follows is my own experience over the last 10 years in many outsourcing contracts working across India, China and Eastern Europe outsources both independent and agencies.

Are you sure it’s for you?

Never “palm off” the job in the form of outsourcing. Otherwise you will be heading down a spiral. Because the important piece of outsourcing is both micromanaging and understanding what the fuck is getting delivered. This way you can either pull the plug on crappy code or influence the right sort of implementation.

If you outsource too early or the core IP you lose the power to radically change the design of your product. Early design is constantly changing especially if you are building something which has never been done before. You want the flexibility to change fast. You need to be under control and know what is going on with all the moving pieces. Read more on this how bad outsourcing impacted Boeing’s Dreamliners (787’s).

This leads me to some key points on what skills you should have if you are going to outsource. Mind you I said “you” because it cannot be someone else you palm it off to.

1. Have a strong background in software engineering.

Loose coupling, Less code, Don’t repeat yourself (DRY), explicit is better than implicit, Test-driven development (TDD), Distributed Version Control System (DVCS), and what .Net develops is all important. Did you understand any of those? If not then you are going to get a piece of crap code. Why is code important? Because it determines the type of engineering culture you build out internally & future maintenance (this is where the hard costs nail you down) and local hiring – quiet frankly great engineers do not like working in a pile of mess.

If you do not know how to code move on or go and learn to code. Anyone with the right attitude and time today can learn to code. See http://www.codecademy.com/, http://www.udacity.com/, https://developers.google.com/university/, etc… plenty of resources online for free. No excuses.

If the outsources delivers crap code you tell them to fix it. If they continue to deliver crap code. You break the contract and provide constructive feedback to them.

Detail detail detail. “The devil is in the detail.” my previous biz partner stressed this to a point where it is now embedded into my psyche and into how I work.

If you are outsourcing make sure that you or the person working 1:1 with the outsourcer are very detail orientated. This way errors are caught fast and stopped at the front line, and where appropriate move fast and fire the outsourcer.

2. People skills

If you have a background working with people (we all do right) and managing those people (oh here we go) then this part will also get smoother. You need to understand you are working with people who have their own lives, family, goals and ambitions etc… so don’t be an ass because you outsourced a piece of work to a “cheaper” labor country.

If it helps, review (even if you have already read it) How to Win Friends and Influence People by Dale Carnegie. The 3 basic principles:

  • Don’t criticize, condemn, or complain.
  • Give honest and sincere appreciation.
  • Arouse in the other person an eager want.

Look, you are going to have to micromanage them. Yes micromanagement ain’t ideal for your immediate employees but for contractors it is a must. They are paid to do a certain job and usually move on. You need to receive quality (refer to point 1 on engineering) and also make sure commitments are completed on time and within budget. Hence the micromanagement.

I also like to emphasize to build a good relationship so you can work with them again. Obviously pending the results of your encounter. Results is all that matter at the end of the day. But, never lose sight of maintaining that level of expected quality. If it drops, give them a chance to correct it by providing constructive feedback. If nothing changes again, then cut the tie immediately.

Remember: “Once shame on you, twice shame on me” (in 1st person)

Right so you have the necessary skills to get moving. Here is where the harder stuff begins.

The checklist!

1. Automate.

As much as you can. Outsourcing isn’t just relationship management. There are a number of balls in the air from managing the relationship to code review & feedback to product questions that need to be answered and/or fleshed out.

Use DVCS (ref my previous blog post) with email alerts enabled for code checkins, comments and issue tracking. Have everyone involved with the job on email alerts so you know when code is checked in or issues logged. I like using Bitbucket for all of this.

I also recommend you put them on HipChat for Private group chat and IM, business and team collaboration. This way you will maintain all communication in the one place.

2. The standards list.

Send the contractor your “standards list” of what you expect out of the engagement. Use Google Apps to write one up & share it if you do not have now. Put a line in the sand. A bar in front on:

  • Expected quality – DRY baby!,
  • Naming conventions,
  • Daily status updates – email or via HipChat,
  • Use of standard industry engineer practices like TDD else you will get code without unit tests!!
  • How everyone can reach each other for questions on product spec or similar ie. Skype, emails, cell #, HipChat etc. Include timezones everyone is working on.

3. Requirements.

Fuck sake man. More detail. Stipulate any API calls, use cases, designs, standards as mentioned above etc.. If you have an engineering background you will appreciate and say “fuck yeah” to what I just said.

No one likes to document things but this small initial investment will weigh in its worth when the final product is delivered to spec. Do not leave anything for misinterpretation.

  • Have a Balsamiq design illustrating all the screens you expect and how they should look.
  • Where applicable provide designs for every screen. Do not let the contractor try to work out for themselves what you want. Never ends well and you get billed for that time.
  • Technical detail around API calls (request & response) with examples, use cases, high levee flow diagram etc..

4. Understand it before you open your mouth.

If you are developing for a channel you have no experience in, ie. Android. Then spend time learning it from at least a “high level” understanding so you can speak the lingo and know when you are getting lied to in the face. If you level out with the lingo then you will get respected more and the contractor will not be able to pull a “shifty” on you.

5. Hiring.

Never straight forward and always requires a ton of work. But this pays off when you have the right contractor on board working with you.

  • Spend time writing up a detailed job spec and list it on oDesk/eLance and wait for the flood of offers. Immediately decline those that have not met all 5 stars criteria.
  • Setup a spreadsheet of all those that applied to keep track of who you short list, their contact details, your last communication with them etc… From the 100 narrow it down to top 20.
  • Interview the top 20 via Skype video (yes you need to see them) and listen for something that will differentiate one from the rest. For me it was getting asked questions I did not have an immediate answer to. Smart switched on engineers are like that and you know you got a winner there.

Remember that at every point in the interview/communication you need to be prepared with a series of questions so you can use those as a base for quality and comparison.

Tip: And when you do engage the outsourcer make sure you stay working via oDesk or similar tool. As much as you may be conned into believing working outside oDesk is worth 10% discount it isn’t  oDesk provides great tools to track your contractors time (with videos) and in the end you get to provide feedback on them. Bad business means bad comments means no future business. So it is in everyone’s favor to be on best terms and get the job done right.

6. Have fun!

Not a long-term strategy

Outsourcing is great when you first kick off a startup and need to fill in skill or time restraint gaps like kicking off a new channel which will interface with your in-house platform (your IP – which you built and are evolving) or design work. But that is where it stops.

Remember that outsourcing is work for hire. Your own company / startup is a labor of love which only you and those that live and breathe it each day share in the office. So if you have high expectations of the outsourcer to care and be on the ball with something they are building or have built then you most likely skipped the crucial part. The part where I told you to own the whole process and be laser focused on the work getting outsourced. You fucked up. You’re at fault not them.

Never outsource your core business. Only channels. Those that are not what I call IP (intellectual property). Your IP always stays in-house managed by you and your cofounder.. and ultimately a kickass in-house team. For example; a business that’s attractive to investors typically has some sort of IP that’s hard to clone by competitors. That thing that makes it unique. It could be a unique algorithm or even data. You’d never outsource that. Stuff that can be outsourced might be a channel eg. a mobile app as long as the IP (say that algorithm) is in the API your local team manages. For a smoother system consider using SD-WAN software as it gives you a better application system and more efficient business operations.

Final note

You are not looking for a “sweat shop”. Find rock stars! That have a history of delivering quality code on time while communicating effectively. Communication decides if you get an apple or an orange when all you wanted is an apple.

If you have any stories (good or bad) please share with me them below in the comments.

Happy outsourcing!
