I've been consulting for some of the world's largest companies for the last three years and have observed three themes that worry me:

  • Agile is a really controversial word, despite the manifesto being quite clear on the matter,
  • Somewhere within every company, there are many, many engineers that have been waiting weeks for test environments, and
  • Engineers have the heaviest, plasticky-iest, and most unpleasant machines in the entire organization

This (hopefully) brief post is about that third point.

Life of an Engineer With Subpar Tools

I'm not talking about DevOps tools. Big companies have plenty of that.

I'm talking about hardware. The things through engineers consume the above tools. The things that engineers will spend eight hours (or more) per day on. The things that make engineers valuable enough for your company to hire them.

From my three years of consulting for big companies, the decision tree that leads to subpar machine choices looks something like this:

  • "Business people" mostly spend their days in Excel, Word, Outlook and Chrome. They don't need something that powerful or that nice. Let's get them a cheap Dell Latitude (example).

  • "Developers" do all sorts of things that amount to needing really fast processors, lots of memory and lots of disk space. Dell has these really beefy Precisions; let's get them that.

What's problematic about this is that it satisfies engineering needs on paper, but completely disregards life as a developer.

Here's why crappy laptops bother me.

  • We carry them. Laptops (thankfully) seem to be more popular than the desktop workstation these days. But because the decision is usually one or the other, engineers have to carry these machines day in, day out. Heavy machines put additional undue back strain, and they take up a lot of space. (Precisions have really large chargers! Tell me that this isn't big! And this is the slim version!)

    Consequently, engineers have to buy bigger, heavier packs than necessary to carry everything and distribute load evenly to avoid nasty long-term shoulder and back injuries.

  • They usually have terrible screens. I can sort of (but not really) empathize with the idea of screens being unimportant for "business people" since the Office suite (and Chrome) aren't graphically demanding (except they definitely can be). I can absolutely not buy this argument for engineers. We spend a lot of our time in terminals and code. Being unable to effectively see what we're developing creates undue eye strain, especially since these displays usually suffer from chronic light bleed. Poor displays also make it hard to write or review code with other people, since anyone watching from the sidelines will get a fantastic glimpse of light bleed filter.

  • They usually have subpar keyboards. Have you ever tried typing on oatmeal? No? Give it a shot when your bored. That's what it's like to type on most crappy laptops. This problem is often exacerbated by engineers receiving stock keyboards and having to go through arcane or confusing processes to buy a keyboard that isn't mounted on play-doh.

  • They usually have subpar trackpads. I am a huge fan of the ThinkPad "nib". However, much like the MacBook's legendary Trackpad (and the Magic Trackpad from which it is based), most laptops have significantly worse versions of these. Trackpads and nibs that lose their pointers are common in crappy laptop land.

Everyone should have the best tools

{{< post_image name="best-tools" alt="Good tools are key!" >}}

There is a simple solution to all of this: give your engineers great tools, and let them do (almost) whatever they want on them.

To the first point (give your engineers great tools): there is a reason why most tech companies give everyone in their company MacBooks and awesome desk-side hardware: having better tools means less resistence in making stuff which means more stuff gets made. This is especially important for engineers since we spend the majority of our day using them.

Engineers should receive the best laptops available on the market. No exceptions. Despite not being a Linux machine, MacBooks make it very easy to develop against platforms that run on Linux. For the Microsoft shops of the world, the Microsoft Surface can't be beat. (The Dell XPS and Lenovo ThinkPad X1 Carbon are close contenders, and both companies have strong and time-tested enterprise support options, but I think the Surface surmounts both quality-wise.)

There are big gains that can be made from giving the best equipment to people in non-technical roles as well (i.e. "businesspeople", which is a terrible catch-all, in my opinion). Behavior-driven development is a great example of this. I strongly believe that better and more reliable software is only made possible when everyone --- product, UX, engineering and business development --- collaborates through the codebase. BDD enables this by turning the typical requirements gathering sessions of Waterfall lore into human-readable code living alongside application source code. The best part about BDD is that because the requirements are code, they can be tested, as little or as often as necessary.

Giving Product analysts or Customer Success engineers the ability to write and test BDD just like developers would is a massive advantage, and everyone having the same (amazing) hardware enables that.

The second point (and let them do almost whatever they want on them) is probably a contentious statement for some of you. Let me clarify.

Engineers should have full admin access on their machines.

Software development is a creative process. Writing software requires lots of tinkering and experimenting. Engineers are lazy, so borrowing existing works is usually encouraged over writing new stuff unless the pain from using existing solutions is so great (or the problem is so niche), that writing new stuff is actually easier.

It is nearly impossible to do any of these things if engineers cannot install or modify things on their own machines.

Companies where developers have to wait over a month to install Git and Docker are a real thing. Companies where developers have to go through a labyrinthian request process to obtain sudo on their machines are a thing. Companies that do this tell me two things:

  1. They do not trust their developers, and
  2. They do not understand what their developers do.

You wouldn't hire someone you can't trust, right? If so, why hire them, say that you trust them and then slap on a quagmire of process and paperwork that prevents them from doing their job most effectively?

Every large company has an Employee Handbook or Computer Use Policy that clearly lays out what can and can't be done. Disk encryption, solid firewall policies and the threat of a massive multi-national entity with more lawyers than anyone thought possible should be enough to prevent most people from trying to do "bad things."

To be clear, I do not think that engineers should have full access to restricted environments. Super-tight security makes a lot of sense there.

A Quick Note on VDI

{{< post_image name="vdi" alt="Seriously, stop." >}}

Many companies employ Virtual Desktop Infrastructure, or VDI, as a cost- and maintainence-saving alternative to managing a fleet of desktops and laptops everywhere. They are great at the centralizing bit, but with one catch: they are terrible at nearly everything else. (I say this as an ex-XenDesktop administrator.)

While virtual desktops make it easy for people to use their own devices to do their work, "using" is a farce. Every virtual desktop that I've used is:

  • Incredibly laggy (you can't fight the network, or virtualization physics for that matter)

  • Based on Windows (which isn't problematic in itself, but it is graphically demanding, which makes lag even worse)

  • Locked down to the gills (because it's easier to do so, so why not?) and

  • Not pleasant to use, especially on Macs and Linux desktops.

This is the holy trinity of a poor working experience for any developer. Any team that is dealing with subpar development woes will probably see massive gains from using local workstations. This is a hill that I die on now when I see it.

NOTE: This differs from having remote SSH access into a Linux workstation through bastion hosts or VPN access into one's desktop at work, both of which make a lot of sense for companies that require high security.

In closing, an analogy

{{< post_image name="cramped" alt="This is absolutely a real thing" >}}

I'll close this post with an analogy.

The way engineers are treated at a lot of companies is kind-of like if a Fortune 100 hired an uber-expensive executive person, gave them the cheapest IKEA desk they could find (because it does the job, right?), were told to always fly in Economy to all of their meetings regardless of criticality (because you'll get there either way, right?) and were told that they have to wait six weeks before they can install LinkedIn on their corporate iPhone because it's not an "officially-approved" app.

Sounds kind of ridiculous, right? That's daily life for most engineers at big companies.

It doesn't have to be this way.

You can’t perform that action at this time.
