ABC: Always Be Coding — Tech Talk — Medium
I need to do this: "Re-invent the wheel. You should implement the most common data structures in your language of choice. Do not rely on common libraries. Implement the following and write tests for them: vector (dynamic array), linked list, stack, queue, circular queue, hash map, set, priority queue, binary search tree, etc. You should be able to implement them quickly."

New Research Tools Kick Up Dust in Archives - NYTimes.com
"But for all its academic potential and efficiency benefits, some see the opening of the world’s archives as a mixed blessing. Archivists who are in charge of caring for documents that have in the past been looked at rarely, and by a relative handful of historians, worry about damage to bindings from careless researchers who flatten books to obtain better images. They also worry about the loss of control, which in some cases can lead to violations of agreements that the archives have with donors of historical materials."

The CAP FAQ by henryr
"The basic idea is that if a client writes to one side of a partition, any reads that go to the other side of that partition can't possibly know about the most recent write. Now you're faced with a choice: do you respond to the reads with potentially stale information, or do you wait (potentially forever) to hear from the other side of the partition and compromise availability?"

"If you are a libertarian and dismayed by the largely critical reaction to Paul's speech, you should understand that much of it is because black liberals, like me, actually expect more of Rand Paul than we expected of Mitt Romney. Again, a lot of us have family whose politics are not very different from Rand Paul's. These are people who don't like foreign wars, who don't like our incarceration rates, and don't like our deficit."

How to work with software engineers - by Ken Norton
(yes, it's satire): "Leadership means setting the bar high and challenging everyone to teleport over it. Show your ambition by committing to project schedules without consulting your team. Being held accountable to somebody else’s promises builds character and brings out the best in people. Think of JFK. He picked a totally random date to land on the moon and NASA beat it..."

Hypercritical: Technological Conservatism
Forgot to bookmark this among discussion and kudos. "At some point, we’re all guilty of looking down upon things that have changed since our own formative years, but this attitude has no place in technology criticism—and it’s absolute poison for anyone trying to create great tech products and services. Not all new ideas represent progress. (Do I really need to spell this out? It seems so.) But ideas should not be rejected based merely on a lifetime of having lived without them. Today’s “unnecessary” frill is tomorrow’s baseline."

Ninja Software Development: Something Sure Is Rank
stack ranking seems like something that someone proposed as a joke in a management article, then people didn't realize it was a joke and did it for real (kinda like 'waterfall'): "Once employees know that they are ranked against each other and avoiding being in the 'bottom 10%' is vital, they will start to alter their behavior to try and avoid being the low man.  This leads to anti-social activities such as information hoarding, sabotage, and grandstanding.  They stop trying to further the group goals in favor of their own."
