I'm a sysadmin. Yes, I shell into production hosts. We have configuration management and the like, our deploys are automated, and most of our logs are aggregated, but yes, there are times when you've gotta log in and see the current state of the system when managing it.

You should treat anything that forces you to log into a prod server by hand as a bug in your workflow/tooling/etc. that needs to be fixed, but you'll never fix every possible bug.

From what I gather the generators use the engines to provide power to the plane in flight, and at issue is software in some computer units that manage those generators. I imagine if the engines are powered off maybe there's some battery power unit, or shore power if parked at a gate, that keeps the computers hot.

I've always wondered how the avionics stuff like this works. I guess they don't completely power down aircraft if they're idle overnight or whatever? I can imagine there's not just a set of keys and an ignition switch in the cockpit like your car.

I imagine (I'm not a pilot and I have no idea what I'm talking about) that is more a question of economics. These planes do not turn off. They land on an airport, get the people and luggage off, they board new people and luggage, then they take off. To shut them down would mean to lose money and they only make money while in the air. Given the price tag for one, it would not be surprising that these kind of planes would be (ab)used for 248 days non-stop.

They have a hangar maintenance once every 6 months taking 1-3 days, where I assume it's turned off at some point.

Every 6 months is 183 days. Not that much of a stretch if some company extends that by 2 months.

loinburger: Jul 10, 2004; Sweet Sauce Jones

I recently changed jobs, and my first task was to fix a Spring/Java project that was originally written by Coworker (me: "fix it how?" boss: "Just... just fix it"). A process starts when the user makes a REST call; this initializes a table (or whatever it's called) in Mongo with a list of sub-tasks that need to be performed, then these tasks are read from and deleted from Mongo as they're executed i.e. Mongo is basically just acting like a queue. There was absolutely no reason to have a persistent queue in Mongo, so I replaced it with an in-memory ConcurrentLinkedQueue. Later, Coworker reviewed the changes. This is heavily paraphrased owing to my lack of respect for him.

Coworker: What happened to Mongo?
me: We didn't need a persistent queue, so I switched to an in-memory queue.
Coworker: But Mongo was the queue!
me: Yeah, now we've got a faster and less complicated queue.
Coworker: But I like Mongo!
me: Tell you what - how about if I write the task logs to Mongo.
Coworker: Yayyyyy!

It also turns out that this is this guy's first time ever using Mongo, so I suspect he reads random blogs on this sort of thing and decides that he's got to shoehorn some random crap into his next project.

re 787 talk, apparently rebooting the plane takes a few hours if this story is to be believed.

Also a pretty cool doc about the architecture of the power systems on the 787, I didn't realize that a lot of systems on other older jet designs were basically pneumatic.

Two and a half years of programming major collage and this loving profession that is progressing and changing at a thousand miles an hour and you guys drop lines like that. Have you seen what you loving nerds have done to me? Look at this poo poo.

This is a loving picture of programming languages up to 2001. I have taken classes for years of my life and know FOUR. C,C++,C# and Java. Two of my known languages are literally inches away from being the same as the other but decided to use entirely different keywords and foundations. If I hear about another person making a programming language that "does it better" and they are in driving distance I am going to commit a homicide. I went out job hunting and look at job details and see this loving rat nest of poo poo I have never heard of being used in my life as a requirement for employment. I just want to program some poo poo and this starting point is five miles offshore in a speedboat with loving wings. How do you people even have an industry? Two thirds of the united states can't even say who represents them in Congress, Pinpoint 15+ countries on a map, install windows, understand a single unix command, or who took Berlin in WW2.

I want in on this racket because I predict in ten years time you will make programming so loving convoluted that you will either cause the end of the world or permanent job security because no one can teach it in school any longer.

You don't know four programming languages. You know four dialects of one. OK, you could argue that object orientation is a fairly major feature, so C could be considered to be more of an ancestor to the others, but it's still all imperative.

But don't worry too much about that. You'll probably never encounter a job that requires something fundamentally different, like a functional (Lisp, Haskell etc.) or�God forbid�logical programming language. As for all those toy scripting languages like Ruby, Python or whatever the current fashion is, as you become more experienced you should be able to pick those up as you go.

Just git gud with the languages you know. Programming skill is separate from knowing the syntax of a language.

C, C++, C# and Java are a pretty good choice for years from now.
