It is simply not true unless you have a pathological idea of "hand-allocation" (which to be fair, some programmers do program like). Let me put it this way ... all "garbage collection is fast" claims are saying the follo

If there's an accident (boom) then the paying customer's payload is destroyed and in most cases they will not have a duplicate payload just standing by to be launched. Building satellites takes a while.

Guys. Stay away. Tcl is awful if you want to write software that doesn't waste hours and hours and hours of your precious time hunting down simple bugs that would not have been an issue in most other languages. - guy who used Tcl in li

Yeah, identifying risk is important. But thinking one can "identify risk" as some random dude posting on Hacker News, criticizing a guy with a lot of experience running cutting-edge tech companies that make stuff like cars and spa

Dude, Photoshop takes many seconds to start up, and as of the most recent redesign it now often takes multiple seconds just to display the new project menu . And this is not atypical of today's software. Forget 16ms, I would be happy

I think the sentiment still applies. Why is this a service instead of just a library I can link and use however?

I don't think "long-lived" is a good substitute for "extremely large". The longer something lives, the better it should be, for multiple reasons -- more time to work on the code, more design iterations, more-thoro

But ... in a text editor you care about lines most of the time. This is what I object to about the rope representation -- it intentionally destroys this information that you actually want available most of the time. I don't think that&

To get the parentheses right, you have to parse the language. There is an extensive body of literature on parsing that goes back decades. Most of it I don't think is that useful. But some of it is about parallel parsing. If you are int

I am not trying to be anti-intellectual, but software currently has the opposite problem, where people decide some idea will Make Everything Better and it turns out that this idea does nothing of the kind. In fact some of these ideas have s

Oh you're that Raph! Hi. Sorry for presuming age + experience level, it's how this came across to me. Actually I think Rush is a prime example of "excited about general ideas that turn out not to be right or relevant to muc

Please read this with a grain of salt as it does not seem practical or necessary. It seems like the kind of thing written by a young person who is excited but doesn't really have much experience. Most of the ideas would not be real-wor

It was the "or indeed in C" that ended it for me right there (though that was compounded by the 'you want to load your 8-dimensional points from a file, where else could you possibly be getting them?' stuff, which shows

Then you get early warning that you need to be paying attention, rather than silently corrupting your data by swapping some coordinates around. No, a real-world case is that I have a giant program that uses my own geometric primitives, an

(a) This kind of thing in many cases is just tedious busywork that you are now making someone do every time they call the routine. What if they have a MyPoint and your procedure takes a YourPoint? And what if your point is 8-dimensional, an

No, because they share a base Entity class.

by jblow 10y ago
The way I do it, each entity has one struct. So a Bullet is one strict and a Door is one struct. They both share common base members that all entities share. But this is all that is really necessary. Once you start getting into components,

The reason this explanation is so widespread is that it is actually not false. However , the actual uncertainty in the Uncertainty Principle takes place at a much deeper existential level, in a more-important way, so this is a woefully inc

Most jobs are not in sales, so regardless of whether this is true, it only applies to a minority of positions. (Though I have no numbers, in my experience sales is the one area where there are lots of women in tech companies, as well as in

In fact this is a reason to be skeptical of this kind of discrimination argument. If the wage gap is happening and is really so drastic, if women are being undervalued so hard, etc, then there should be a massive Moneyball-style opportuni

You are talking to someone who has done 3D rendering professionally for 21 years. What's your background?

Yes, absolutely, and in fact I think it would be a much better program.

by jblow 10y ago
It is a little confusing because we are talking about both rendering and GUIs, but ... "retained mode" in this case refers to the GUI itself, not the method of drawing. Motif and Xlib are "retained mode" in the GUI sense
