Computing setup, software focused

Windows

My company gives software/firmware developers a very capable Windows laptop.  It's got 32 cores, 64 GB of memory, and a 500 GB SSD to which I was able to add another 2 TB SSD.  There are a couple downsides to this machine -- it's kind of heavy and the corporate IT team has this laptop very locked down.  All software installed on it must be on the approved software list which I understand.  It makes it harder to use my corporate laptop as a good development environment though.  I compensate by using Linux machines for the actual development work and relegating the Windows machine to acting as a terminal plus using it for web browsing and corporate communications tasks such as email, Teams, and Slack.  I was able to install VMware which allows me to use the laptop to run Ubuntu Linux VMs which are used for occasional software builds and to host some FPGA development tools to program the firmware I develop onto the embedded hardware it targets.

  • Vim - I've been using Vi/Vim as my editor of choice since I took a job which gave me a Sun workstation on my desk.  I've got friends who love various editors such as Emacs, Visual Studio, Notepad+, Atom, and a few others.  I've occasionally experimented with other editors but it's really hard to overcome the muscle memory which comes from using Vi for 35 years.  The benefit is I'm still using a few macros I created that long ago.  I prefer GVim, the GUI version of Vim for its ability to resize windows.
  • Putty - I've got Putty profiles for all the Linux machines which I connect to regularly.  Each includes X11 forwarding which gives me the ability to launch X11 apps on any of the Linux hosts I access.  I know that Wayland is more modern but most of the Linux machines I'm accessing run old enough versions of Linux to make Wayland too much trouble to try to use.  Putty supports both SCP and serial connections, making it a handy way to connect to serial console ports.
  • WinScp -  This is a great little network file transfer program which supports the SFTP and SCP protocols.  I often use one Linux host to build my software and another to install it so being able to easily transfer files is a necessity.
  • VcXsrv -  Since so many of the tools I use require an X11 connection, I need to run a X11 server on Windows.  I actually petitioned our IT group to add this to the approved software list.  It can be a little buggy at times but getting free software approved is always much easier than asking for commercial software be added to the budget.
  • TeraTerm -  Believe it or not, sometimes I need to transfer files to an embedded machine which only offers a serial connection.  TeraTerm supports ZMODEM transfers which makes exchanging binary files much easier in that case.
  • Kdiff3 -  Capable free GUI file/directory comparison tool and one of the few allowed on my work laptop.
  • Microsoft Outlook - Outlook seems to work adequately for basic email and scheduling needs.  It has a terrible search feature which makes it difficult for me to find past emails I need to reference.
  • Microsoft Teams - I have never cared for Teams but it's a necessity to allow me to join meetings while working from home.
  • Slack - Most of the time this is okay but it's very quirky.  It's a necessity to allow easy connections to people while I'm working from home. 
  • Google Chrome - It's the browser chosen by our corporate IT team.  I guess it's a necessity since it's captured the majority of the browser market but I must admit that I've never really cared for its UI. 
  • Windows Calculator -  Having a calculator capable of hexadecimal and binary operation is a necessity at times.

 Linux

All of the embedded devices I work with run some version of Linux.  Some actually have multiple copies running on different CPUs.

  • Vim - Vim comes preinstalled on all the Linux machines I need to access.  I do often still install Gvim to make it easier to edit files over an X11 connection.
  • Putty - I manually install Putty on Linux machines.  It makes it easy to connect to devices on the Linux machine which use a serial port.  It's also handy to do that via an X11 connection.
  • GNU Screen - Screen makes it very easy to maintain a persistent connection to a machine which is necessary as some of the firmware builds take over an hour and network hiccups used to kill the build before it was done.  Screen allows me to reconnect after the network issue and see the build continuing as if no interruption had occurred.
  • Exuberant Ctags - I've been using ctags to make navigation through unfamiliar code easier for 30+ years now.
  • Ack - Ack allows me to do a recursive search for files which contain some string and to limit that search to source files or some other category such as Bitbake files.  I use the ack executable which is implemented as a single perl module which makes it trivially easy to install on Linux machines.  I know there are faster source search tools available but this one is easy to use and works well for me.
  • Kdiff3 -  Capable free GUI file/directory comparison tool.
  • xxd -  Sometimes I need to examine binary files and this tool is readily available on Linux machines.  It can also help transfer binary files in a pinch by converting a file to its hexadecimal ASCII equivalent, transferring it, and using xxd to convert it back to binary.
  • bash - I rely on the bash shell along with awk, sed, grep, find, and other standard GNU Linux tools for the vast majority of my scripting and interactive use needs.  I rely heavily upon bash scripts to help automate much of my development process.

Apps for both Mac & iOS

Here are the apps I run on both the Mac and iOS.

  • Music - Sometimes I like to have background music playing to help mask out distracting sounds while I'm working from home.  I have a few playlists which work well for this purpose.  I buy most of my music in MP3 form from Amazon or Bandcamp and import the MP3 files into the Music app.
  • Apple Mail -  It's free on Apple devices and does a reasonably good job of keeping my mail accounts in sync between my Mac and my phone.
  • Apple Numbers -  Even though this is a spreadsheet, it can also function as a lightweight database app.  I use it to keep track of audio books and e-books I own and which I've read.  I have quite a few of these lightweight databases.  I used to use a great database app called Bento made by FileMaker which had versions for Mac and iOS.  It was discontinued in 2013 and I haven't found a replacement I like better than Numbers although I do occasional search still. 
  • Google Calendar - I like it because it seems to be the most flexible in scheduling recurring events.  For example, you can choose the 3rd Saturday of each month or the 21st day of each month.
  • Microsoft To Do -  A reasonably good cross platform to do app.

Mac 

My old Intel Mac Mini is getting long in the tooth but still manages to support some of my work and all of my personal computing needs.  Here are some of the apps I run on it.

  • ChronoSync -  I've been using ChronoSync for backups for quite a while now and I've very happy with it.
  • Little Snitch - I insist on running a top notch firewall program and Little Snitch fills the bill nicely.
  • GnuCash - Since I pay most bills electronically, GnuCash lets me keep track of my checking account easily.  I really like its ability to change the sorting from ascending to descending dates since that makes it much easier to compare with my bank's statements.
  • Waterfox browser -  I've always liked the Firefox browser for how easily its UI can be customized and for the rich set up plugins which allow safer browsing.  Firefox lost me as a user when they started on their quest to shove AI in every aspect of the browser.  Waterfox is a reasonable fork of Firefox which does not include the unwanted AI features.  I use this for all my general purpose browsing.  I also use the Chrome, Safari, and Vivaldi browsers each for a special purpose.  It limits having to worry about whether cookies from financial or social media accounts are being seen by other websites.
  • Vim - The command line version of Vim comes preinstalled on Mac machines.  I still install MacVim to make it easier to edit files and to be able resize windows.

iOS

I use the cheapest iPhone available whenever I need to replace my phone as my personal device.  I've got iOS software I depend upon to make life easier.

  • iTunes Remote - This allows me to easily select the playlist from the Mac's Music app.  I used to also use it for pausing music when I had an incoming call but now I rely upon an Anavi Macropad 10 for that purpose which allows me to pause songs without fumbling to bring up an app on my phone.
  • PCalc -  Having a calculator capable of hexadecimal and binary operation is a necessity at times and I'm not always near my Windows laptop.
  • Overcast - This is my favorite podcast app.  It has the best UI of any iOS app I can think of.
  • Audible - Listening to audio books keeps me sane when commuting to work or in warmer weather when I'm doing 3-4 hours of yard work. 
  • Libby - App which makes it easy to borrow library books.  Mostly e-books but they also have audiobooks.
  • Hoopla -  App which makes it easy to borrow library books.  This seems to have more audiobooks and graphic novels than Libby does.  They also let you borrow and stream digital movies and tv content.
  • Two factor authentication apps -  I enable two factor authentication for any website which supports it and apps such as Authy, Google Authenticator, and others make that possible.

Computing setup, hardware focused

Since I work from home the majority of the time and my job involves writing software and firmware for multiple small embedded ARM based devices, my computing setup tends to be a bit more complicated than normal.  I'm also cheap so I've gotten almost everything on sale.

 

The picture above shows some of the equipment at home which makes it easier for me to switch between the many devices I need to use both for work and my personal computing needs.  The red surface everything rests upon is a grounded anti-static mat which is a necessity as I often need to use bare circuit boards for easy access to JTAG connectors.

  • Philips 4k monitor.  I often have ssh sessions with anywhere between 2 and 5 Linux systems simultaneously.  That many terminal windows take up a lot of screen space so the fact that a 4k monitor has 4 times as many pixels as the HD monitor I'm stuck using at the office has made working so much easier.  I got this at a good price thanks to a Black Friday sale 3 years ago.
  • IOGear KVM switch.  I usually switch between my work laptop, my Mac Mini which is mostly for home use, and a Raspberry Pi 5.  Since this is a 4 port KVM switch, that leaves an extra set of cables to connect to other devices as needed.  I had a cheaper KVM but the move to a 4k monitor forced me to upgrade to one which supported the higher resolution.
  • Technical Pro rack mount power supply.  This allows me to easily power on or off any individual device in my setup as needed.
  • Raspberry Pi 5.  This is a great development device as there are much better free development tools available for Linux than there are for Mac or Windows.  That provides me with a lot of flexibility in my development and debugging tasks.  It's my favorite computer to work with.
  • Anavi Macropad 10.  This device comes with CircuitPython installed which makes it very easy to configure the key codes it can to send to my Mac.  I like this one because it's also got a rotary encoder (which can be used to easily change the volume) with a button on top to pause the music.  I often use my Mac Mini to play background music while I'm working.  Being able to pause music playback, skip to the next song in the playlist, rewind to the previous song, or adjust the volume on the Mac while my keyboard and monitor are switched to my work laptop via the KVM is very handy.  The situation which this keypad helps with most is when I get a call from someone at work and need to quickly pause the music in order to take the call.
  • Canon PIXMA G6020 All-in-One Megatank Printer - It's affordable, reasonably fast at printing, doesn't use proprietary ink cartridges, and has copying and scanning capabilities as well.  We've had it a year and are still on the original ink bottles supplied with the printer.  I think we've been through about 6 reams of paper during that time, most of it double-sided.

 

The picture above is an EDID (Extended Display Identification Data) HDMI adapter.  It causes the computer which it's plugged into to continue thinking that the 4k monitor is still plugged into the computer when it's actually switched to another computer via the KVM switch.  The EDID HDMI adapter shown above is connected to my work laptop.  I've got another one plugged into my Mac Mini.  This prevents the windows on whichever machine from being rearranged when the monitor configuration changes via the KVM switch.  More expensive KVM switches sometimes include this capability without requiring an external adapter like this.

Making changes to your development setup easier

As I'm occasionally assigned new projects at work and as those projects progress, I find the need to update my development environment on a regular basis.  Having the ability to customize my setup allows me to be more productive.

To that end, I have defined a few bash aliases which help make this process easier for me.  These aliases are defined in my ~/.bash_aliases file.

#  config bash
alias   cfgb='gvim ~/.bash_aliases'
# config vim
alias   cfgv='gvim ~/.vimrc'
# source my bash aliases to pick up any new changes
alias   redot='source /home/rod/.bash_aliases'

You'll notice that I have an alias to make changes to my vim setup.  It makes sense to also have a vim macro to read any new configuration settings or vim macros.  This macro is defined in my ~/.vimrc file.

" source .vimrc ro pick up any new macros
map \.  :source /home/rod/.vimrc^M

Default apps for 2023

Lately, I've seen a lot of the "what apps am I using" type posts, apparently prompted by a podcast episode.  You can see a collection of what a number of people are using here.  I find these interesting as they're a good way to discover new apps which I hadn't been aware of previously.  These are the apps I use for my iPhone, Mac, and Raspberry Pi at home as well as the Linux and Windows machines I use at work.


  • Mail Client: Apple Mail, Outlook at work (barely tolerable but dictated by the IT team)
  • Notes: Apple Notes for shared notes, Editorial for notes I don't want on the cloud (such as those containing sensitive information such as birthdays)
  • Chat: iMessage
  • Camera: Apple Camera, Night Capture for evening sky photos
  • Photo Management: manual sync into directories on my Mac
  • Photo Editing: Preview on Mac, IrfanView on Windows
  • Calendar: Google Calendar - I like it for its ability to do custom repeats and for ease of having more than 2 notification reminders
  • Browser: On Macs I use Safari for lightweight browsing for its ease of sharing bookmarks with mobile devices, Firefox for general browsing because it has a richer collection of security plugins.  At work I use Chrome (barely tolerable but dictated by IT).
  • Backup: ChronoSync
  • Read It Later: Instapaper
  • RSS: Inoreader (web and app)
  • News: RSS feeds from news sites which lets me keep up with events without being distracted by things I'm not interested in such as sports
  • Podcasts: Overcast (great performance and the best UI of any app on my phone, bar none)
  • Books: Kindle, Audible, Libby, Hoopla
  • Database: Tap Forms (good sync between mobile and Mac)
  • Personal Finance: GNUcash
  • Password Management: 1Password - with 600+ non-trivial passwords to remember, this is a must
  • Music - Apple Music, Remote app to control desktop from my phone
  • Editing (code and general) - MacVim on Mac, GVim on work machines (Windows and Linux)
  • X Servers - XQuartz on Mac, VcXsrv on Windows
  • SCP client - WinSCP on Windows, scp from the shell on Linux/Mac machines
  • Terminal emulation - putty on Windows and Linux machines
