Over-abstraction is as much of a problem as under-abstraction. If the abstraction isn’t improving your ability to produce good code, it’s a bad abstraction. I’ve worked with a lot of abstraction patterns in a lot of languages over the 30 years of my career. Any of them can be good or bad. Unthinkingly applying them is always a problem.
Unsurprisingly, that goes for just about any idea in software development. I worked in one code base that heard small functions are best, so every function was less than three lines long. You don’t gain anything by replacing `lst.get(0)` with `get_first_item_in_list(lst)` (in fact, understanding becomes much more difficult), but breaking down functions into the smallest units that make sense independently within the business domain can be very helpful, both for understanding and testing.

While I agree with you almost universally, I think in this case, the pricing is meant to be part of the loss aversion technique the creator is employing.
My problem is there is no such thing as a lifetime subscription anymore. More like "until the company gets acquired and the new parent company gets bored or until I get bored, whichever comes first".

There is an ecological cost to miles and miles of solar panels. Desert ecosystems are extremely fragile, and these kinds of projects can be very damaging. It’s not just wasteland. (Said as a desert Southwest denizen and lover who gets the impression that many people think, “oh, there’s no trees? It’s unimportant land.”)
I want the Utes to have success in this, but I don’t want the general attitude to be “trash the desert because there is sun there”.

The first series of courses in my CS program introduced us to building a pascal interpreter using scheme. It all depends on the pedagogical needs, I suppose.

I doubt it. A human should be able to tell whether they are breaking the law or doing something that is dangerous and, thus, stop. If a human moved forward with something they should have known was dangerous or illegal, it would be grounds for negligence or worse.

Extremely rare diseases and diseases that have no known treatment options are given more lax rules for testing. Without that, there would be no way to develop treatments for them, but it comes with a side benefit of providing a method to attempt new treatment modalities.

Ships lost at sea are also still commissioned and patrolling. I suspect it is part of naval culture.

Let's be clear here, though: it's the airlines who refuse to buy an aircraft with additional training requirements. Pilots can only fly one aircraft type, and retraining to a different type is an expensive proposition. If Boeing could make an aircraft that fit under the 737 type, they really had no choice but to do it.
They also probably could have succeeded, too, if not for other systemic problems within the company.

> Design a damned airframe that's airworthy without needing stabilization hacks.
The 737 Max is stable, as all commercial aircraft have to be. MCAS is not a system to take an unstable 737 and make it stable. It's a system that was meant to take a changed 737 and make it fly nearly identical to a previous 737, so pilots didn't have to get a new type rating (a very big deal for airlines).
Juan Brown, a commercial pilot and certified flight mechanic, on YouTube has a (great series of videos)[https://www.youtube.com/playlist?list=PL6SYmp3qb3uPp1DS7fDy7...] talking through the mess that is Boeing made of MCAS, including what the actual problem is.

One of the most important things I've learned over the years I've managed people is that processes and policies of any sort are two-edged swords. It's easy to add a policy, and to convince oneself of the advantage the policy will confer. What is very often ignored is the cost of a policy.
Every policy comes with an associated cost, and those costs can add up quickly. People always ask "what will this policy make better", but, just as important, is to ask, "what will this policy make worse".

Ksplice @ Oracle | Full Time | Remote | https://ksplice.oracle.com/
The Ksplice group at Oracle develops technology to patch the Linux kernel and applications while they are running, eliminating unplanned downtime for systems running Oracle Linux and keeping up-to-date with known security fixes. We're looking for a full stack software engineer and a systems engineer to join our team.
The full stack software engineer will help us expand the web services we provide to our customers and the tools needed to provide those services. You must be comfortable with the entire stack, from the Linux shell at the bottom to Python and Django (or similar) at the top (bonus points for experience with Terraform or Ansible). You must also be willing to assist with operational tasks. Expert knowledge of Python and web development as well as experience deploying to Linux is a must. Contact [email protected].
The systems engineer will help us Ksplice patch even more of the system, support new releases and improve our workflow. You'll like working at all levels of a Linux system, developing tooling in Python+bash, analyzing security vulnerabilities in Linux kernel patches, enhancing the Ksplice tools and improving the workflow. Expert level C/C++ programming, experience developing the Linux kernel and an understanding of security issues and defences in compiled languages are required. Contact [email protected].
More information about Ksplice is available at http://ksplice.oracle.com/. Oracle is an equal opportunity employer.

We are a distributed team engineers working to provide rebootless updates for supported kernels and "restartless" updates for supported applications.

You must also be willing to assist with operations tasks. While our goal is to automate everything we can with code, there are times where ssh and the bash command prompt are the best tools for the job.

Ksplice is the leading technology that allows administrators to patch the critical components of a Linux system on the fly with zero downtime and zero disruption. We're looking for an experienced DevOps engineer to join our team. As a DevOps engineer, you would be responsible for automating the deployment, monitoring, and day-to-day management of Ksplice's infrastructure for building and serving critical security "hot fix" updates for various flavors of the Linux kernel and for user space applications. At any given point, this may involve ssh'ing into a machine, updating a configuration manifest, troubleshooting a running system, spinning up a docker registry, or providing guidance on the best deployment options for a new service.
The Oracle Ksplice team is a remote team, so you must be comfortable interacting remotely and working autonomously. We are a small team that expects its members to be comfortable with self-directed work.
More information about Ksplice is available at http://ksplice.oracle.com/, and you can contact me by email at [email protected] for more detailed specs. Oracle is an equal opportunity employer.
Tech stack includes MySQL, Linux, Python, Django, Puppet, Ansible.
