Screen, tmux, et al. are great. But here's another way of approaching the same problem: Emacs can serve as a superlative terminal multiplexer if you're willing to give it a shot or if you're already an Emacs user, but do not

Update-related throughput and index problems are only a problem if you update tables. You can use an append-only structure to mitigate some of that: insert new entries with the updated statuses instead. You gain the benefit of history also.

No, it is not bad practice. Only developers who don't care about money actually coming through the door -- the same ones that get caught up in a local maxima trying to perfect the imperfect -- say that it's bad and that you should

It's not unbelievable if you know and use Emacs and dired. dired will use `ls' if it is available. You can also control the arguments passed to `ls' if you want to customize sort order and suchlike. You cannot trivially do th

In a similar vein in Emacs: M-x zone Every time you run it, it triggers a random screen saver effect. Fun when it's on a timer and triggers so your work colleagues wonder wth is going on.

This is a great way to tell everyone you've never had to do this type of migration. Oracle's got a lot of nasty things going for it, for sure. But there's a reason people still use it: part of it is vendor lock-in, of course;

Fitzrovia is laced with fibre; the entire area is/was host to a large number of broadcast service providers, media companies, telcos, etc. Running out of fibre is not likely in that part of London.

LDAP's full of secrets. It's a great way to keep tabs on what's going on in a company. And to think that you can get nearly all of it with anonymous access. Team or department mergers before they were announced? Yep, I'v

fzf won't work in shell-mode as it does not handle curses-like apps. Thus, `ezf.el' avoids that problem by using Emacs as the fuzzy searching facility. To say nothing of the fact that this is a fine example to re-use for, similar,

Graph theory underpins nearly everything we do in software development and computer science. Networkx is an expansive -- though not the only -- package for Python that'll solve 90% of people's problems.

Laying out a graph so it's "friendly to humans" is a seriously hard problem. I've built complex DAG workflow engines using networkx and its layout tools and they worked just fine. But, yeah, I guess it depends on what yo

But beware row-level security. It's great, but the query planning is a huge mess, and you can end up with serious performance issues real fast if you're not careful.

Using audit tables is another approach that avoids rolling up the data periodically, and you avoid all the needless complexity this approach can introduce; particularly if you're not 100% sure you need it. You gain temporal querying wi

Oracle has query hints; pg does not. Query planner hinters are useful. That's my point.
