IMO All it exposed was writing past the end of buffers.

There was no memory corruption previously due to partially to luck, and partially to heavy testing (which would have exposed most forms of memory corruption).

I think it is fare to say that the change was a cause of the vtable corruption occurring, since without the change it didn't happen.

Once this is discovered, you need to rethink your change plan for the next release; if you back out this one change, your software will return to a working state. Whether doing that, or fixing your buffer overflow is the correct thing to do depends on a lot of specific factors.

Many problems can be solved with either macros or higher-order-functions. The advantage of macros is two-fold (macros also have disadvantages, and Lisp allows you to use either solution; deciding which to use is often a matter of taste):

1. Syntax can be more familiar

2. Performance (to the extent that there is overhead for functions-calling-functions).

For example, let's consider a hypothetical lispy language that doesn't have a short-circuiting "and" operator. Macros would let you implement something to used like this:

  (and (foo x) (bar y))

Higher order functions would require you to do something more like:

  (and (lambda () (foo x) (lambda () (bar y))

More noise, and more work for the optimizer (or in the worst-case, more work at run-time). Languages that rely heavily on higher-order-functions will tend to have terser syntax for anonymous functions. For example in javascript you might do:

  and(()=>foo(x), ()=>bar(y))

Japan has a history of train-driving sims: https://en.wikipedia.org/wiki/Train_simulator#Driving_simula...

What I described was for bugfixes, not features. Features were set in stone way before this.

I also maintain that it is impossible to know which changes depend on other changes. In one case, applying a bugfix that changed the order of allocations at startup caused vtable corruption somewhere else because it changed how much padding a particular malloc() call was returning, and someone was writing past the end of their allocation.

[edit]

Also note that what you described is not CI; things are developed on their own branches and not integrated immediately.

It also means that if you subtract two timestamps, you might not get the actual time between them. Though this is also true of most ways of representing time (TAI being a notable exception).

Next we need someone running on a platform promising "Truth, Justice, Freedom, Reasonably Priced Love, and a Hard-Boiled Egg"

I didn't work on this project, but I've been involved with similar ones.

There is a process for getting a change into version control. Each change needs to have a (virtual) paper trail: motivation, risk analysis, sign-offs &c.

If you can't get something into VC quickly, you can't really do CI.

The obvious solution would be to have an integration branch that doesn't need the process to get in, do CI testing on that branch and then make the process for merging to the real branch.

I've never seen this done personally, but I have been told some places do it, and then you end up with "Change X, which got approved had a dependency on Change Y that didn't get approved and we didn't realize it until now because Change Y was put in the integration branch before Change X"

My 18 year old daughter is the same (and also can't read an analog clock). Despite me using "quarter to," "quarter past," and "half past" regularly throughout her life. And we having analog clocks in most communal spaces in our house. And we drilled her on analog clocks for two summers in a row...

In one of the MD boarder counties (Montgomery maybe?) it at least used to (and may still) be illegal to posses even sparklers or fountains. And they were serious about enforcing it. Cops would stake out VA fireworks stands and radio in license plates to cops in-county. Since even possession is illegal, it's a confiscation and fine the moment you cross the boarder.

Thanks, I was like "that looks a lot like a slipped sheet-bend," but could tell that something wasn't quite right.

Bowline is inappropriate for anything that you need to apply tension to while tying (like your gym shorts).

Neither my parents nor my wife's parents have their desktop connected to their router. The cable modem isn't even in the same room as the desktop.

[edit]

If it matters, my mom no longer has a desktop (she uses a docked laptop now), but it is true of the docking station and was true of her previous desktop.

So similar origin to the Imperial acre; which it is very close in size to:

  You have: 175*24m^2
  You want: acre
   * 1.0378426
   / 0.96353724

I didn't know what ESP was; from some googling, it appears to notify you when someone is aiming at you?

A 5 port 2.5GbE switch would upgrade this to 5 total ports (4x 2.5GbE), and costs less than $100. If you only need 1GbE then it's even cheaper.

Outside of home-labs, it's rare for me to see any devices connected to the LAN side of a wireless router these days, and more than 1 (i.e. the non-portable device that is closest to the router) is exceedingly rare.

I haven't lived in Indiana in over 20 years, but is the law for mortars still:

Legal to posses

Legal to buy and sell

Not legal to use

That was always a bit silly to me. Stores would even have you sign a waiver that you weren't going to use them in Indiana.

One corollary:

Your students will be mad right away if you teach them the terse syntax, but mad later if you teach them the verbose syntax.

Note that the footprint of the store is very small, and CRTs are very large, so "no room" doesn't mean they have a lot. Presumably if they were flying off the shelves though, they would make room.

Just a week ago, I called up the local games store to ask if they wanted my 19" CRT (for free) and they said they didn't have room for any more CRTs, so I'm going to take it to e-waste.

I've never lived in Seattle, but I know that Haggen was a casualty of The Safeway/Albertson's merger[1]; I can't speak to their quality.

Safeway and Albertsons had already bought up many grocery stores prior to that merger. When I was a kid, we knew which grocer had the best butcher and which had the best baker, and neither were chain stores.

1: Granted Haggen isn't entirely innocent here; they saw a potential growth opportunity and over-leveraged.
