thanks cil...

interesting. It was caused because I tried to constrain a generic parameter so I could call stuff on it, but I loaded the generic parameter as a reference rather than loading its address, which apparently constrained needs.

hm, Typescript looks cool but I'm afraid there's no way to make it work with the custom ASM system imposed on us at work

Sea Dragon (rocket)

The Sea Dragon was a 1962 design study for a fully reusable two-stage sea-launched rocket. The project was led by Robert Truax while working at Aerojet, one of a number of designs he created that were to be launched by floating the rocket in the ocean. Although there was some interest at both NASA and Todd Shipyards, nothing ever came of the design as NASA's Future Projects Branch was shut down in the mid-60s. At 150 m long and 23 m in diameter, Sea Dragon would have been the largest rocket ever built. Truax's basic idea was to produce a low-cost heavy launcher, a concept now called "big dumb booster...

A typical launch sequence would start with the rocket being refurbished and mated to its cargo and ballast tanks on shore. The RP-1 and nitrogen would also be loaded at this point. The rocket would then be towed to a launch site, where the LOX and LH2 would be generated on-site using electrolysis; Truax suggested using a nuclear-powered aircraft carrier as a power supply during this phase. The ballast tanks, which also served as a cap and protection for the first stage engine bell, would then be filled with water, raising the rocket to vertical. Last minute checks could then be carried ou…

Anyone up for some input on whether a question (or two) I'd like to ask would be a good fit for Programmers?

Telastyn

go ahead

nhgrif

So, first question, broadly is, "How do I un-code-review my code?" That is... I've got perfectly good working code. What are some good techniques I can apply to reverse some bad practices & bugs into the code? (For the purposes of then showing to someone else to test their abilities or perhaps use in a classroom for education purposes)

Telastyn

nope, too broad - there's a bunch of different "answers" for the question.

nhgrif

And then the follow up question is whether or not showing someone code like this is an effective means at all for determining someone's abilities as a programmer (like in an interview)

ratchet freak

you mean how to write "bad code"?

nhgrif

2:08 PM

Sort of

ratchet freak

the follow-up is also off-topic

Telastyn

probably not, as "is this a good idea" is probably a matter of opinion.

and I wouldn't be surprised if there isn't already a question for that.

ratchet freak

but determining aptitude of a programmer is too broad and doesn't have a answer

Q: Are modern IDE's a 'crutch'?

I have recently been working on a c++ project in a linux environment, utilizing a text editor (GEdit, not a real IDE) and command line. At the same time, where I work we use VB.NET, and Visual Studio of course. This got me thinking... My question is essentially this: are the down-to-earth coding...

Shouldn't be much of one. I thought all the IDE holdouts had died off.

@Telastyn nah, they all moved from "IDEs" to "editors" (with a zillion plugins)

I still occasionally hear people use "Sublime w/ FooPlugin does X" used as a premise in style/convention arguments

Q: Is it bad to work around the system to have a question ban lifted?

I have a question ban on Programmers SE. I deserved the ban, and I have learned what questions are appropriate for the site. In order to have the ban lifted, I need to make enough positive contributions to outweigh my negative contributions. These positive contributions cannot be achieved by a...
