What do you use Lua for?

fullouterjoin · 17 days

Most of the specifics don't matter. Let's say the targets range from 1MB to a few hundreds MB RAM, OSes from some custom minimalist scheduler to full blown Linux 2.6, and work with Lua 5.1, and we do a lot of networking.

As for performance penalties, it's hard to evaluate, because they turn out to be irrelevant. For that kind of target, old-timer techies want to believe that C/ASM style optimizations are still relevant, but they aren't. You spend all you time waiting for UART frames, if not TCP packets over GSM/CDMA. So apart from drivers, and some DB interface to keep out of RAM big stuff which wouldn't fit in, we only use profilers to find gross bugs which affect o(n) asymptotic complexities (i.e., very rarely). And Valgrind on an x86 host does the job perfectly.

I guess things would be different:

if we had to perform intensive computations on the embedded devices, and these weren't supported by dedicated DSPs. I can't think of many business cases fitting that description.
if we were running on small micro-controllers (less than a few MHz, less than a few hundred KB of RAM). This is a legitimate use-case, for large-scale cost savings or drastic energy saving constraints, at least when the application remains simplistic enough, but it's not ours.
if we had a UI to drive on limited hardware, were responsiveness must be under 0.1s if you don't want to gross out every smartphone owner.

LDT, the official Eclipse plug-in for Lua development, supports interactive debugging.

It's not as well known as it deserves because it's a pretty recent project, but it works just fine. It's probably more intuitive if you have some previous Eclipse experience, though.

For embedded development: technically it's still C from customers' and management's PoV, but I get most of Python's development speed for those 95% of times when C's speed isn't needed.

Fair enough for the bisexual/non-exclusive abusive association. I would have thought that male / female partners respond to more deeply different needs than blonde / brunettes, and that one wouldn't address adequately the needs addressed by the other, but I might be wrong (and I don't need to be right about this for my personal development).

Something which I find annoying is the supposed higher moral ground claimed by "serial polygamists" wrt "parallel polygamists": people who dump their partner every couple of years, whenever they feel like experiencing something new, thus wrecking the sentimental life of someone they pretended to love, if not tearing apart families. If your lifestyle is open to multiple changes of partners along your life, you're a polygamist, whether you drop previous partners before or not. Minimizing pain around you might give you a higher moral ground; the order in which you seduce and dump people might not.

Anyway, I hope you dumped your ex for better reasons than her having indulged in her sensual exploratory instincts a couple of times.

So you divorce your wife because she discovered that experimentation was of tremendous importance in one's sex life; then you discover for yourself that experimentation is of tremendous importance in one's sex life.

OK, I present it in a trollish way, but when I read your message, it sounds like her having a couple of affairs is like an obvious reason to dump her. It might be a reason depending on circumstances, but it's certainly not obvious. Even more so in your case : if you end up discovering that you're deeply bi, you're doomed to be frustrated in any couple agreement which doesn't allow for a bit of leeway.

In Europe, you get more vacation. Here in France, 7 weeks mandatory plus bank holidays for most people, can be more depending on your branch or what you negotiated personally.

It's a very insensitive question, if not a conscious troll. However, I feel like playing the Devil's advocate.

Such a level of genius is highly unusual. Without entering the muddy waters of why it might be so, women also are a marked minority in top-level mathematics. The combination of these to odd occurrences is very odd.

Another thing widely believed, about mathematicians of both genders, is that they tend to be less image-conscious and less focused on looks/fashion than average. It's perceived as very unusual of them to put the efforts it takes to be "hot". Combining the "female + top mathematician" unlikely combination with the "look conscious + top mathematician" unlikely combination would increase the oddness factor to ridiculous heights.

Now why did you mention her to your friend, and why could he have been interested by it? It's not your shared passion for mathematics that made your professor's story worth sharing, it's the anecdotal oddness of her story (even if you only focused on her precocious gifts, and not on her gender). It's not surprising that he looks about even more unusual aspects in the anecdote.

And here is another defense angle: maybe he finds the idea of such a super-smart woman incredibly attractive. Being a typical man, he also needs a woman to be physically attractive to fall in love. So he wonders whether she's the unlikely incarnation of the perfect wife he'd dream to marry. Being more interested in finding the perfect partner than in mathematics is a common way to prioritize one's concerns, for both genders (would you be more surprised to hear women pondering a guy's physical features, or the same guy's scientific achievements?).

So, your life sucks, in a large part because you're obese. Yet, when facing the choice between eating or not eating, you can't help choosing to eat. Is eating giving you a lot of pleasure, to the point where you forget the price to pay until it's too late? If so, how is it that guilt doesn't ruin your pleasure of eating?

I'm not judging, I'm trying to understand. I can put on unwanted kg if I eat and drink in excess, but once my figure in the mirror displeases me, I can't help thinking about it when I contemplate grease or booze, and it disgusts me from enjoying it. I'd bet if I reached a point where I couldn't run and move as I wish, I couldn't stand to swallow a thing until my body became fully functional again. I cannot understand how being obese beats eating only Brussel sprouts for years, if that were necessary.

Be cheated on once, shame on them. Be cheated on by all your partners, shame on you.

If there's something wrong in all of your relationship, the thing that's wrong is you.

ElderCunningham · 1 month

Being cheated on by men seems to be a key part of her identity. Gosh, she even needs to clamor it in national newspapers.

So, it matters, because it "upgrades" her status from betrayed woman to spectacularly, humiliatingly, record-settingly betrayed woman. If she's into that, cool for her after all.

ElderCunningham · 1 month

She actually seems out of his league.

I see what you mean, but you can't know until you've seen his bank account.

It's almost impossible to find a balance where all three people are on equal footing

Indeed. So for something like that to work, you need everyone to find their balance while being on an unequal footing. Egalitarianism won't get you anywhere here.

That mainstream monotheism was introduced in the Roman society by Christians.

Various incarnations of a solar cult superseding other gods, with Holy-Trinity-like questionings about the notion of a god's indentity, have preceded acceptance of Christianism. Look especially for Sol Invictus, but don't forget the batshit crazy Heliogabal, etc. The varying opinions of different emperors on the social usefulness/nefariousness of these beliefs is also worth investigating.

he asks for a subject, not an answer, and his question is interesting. While avoiding homework cheaters is desirable, I don't think this post qualifies as unwanted.

Here comes again my Lua pet peeve: because it has generic mechanisms which allow to redefine basic services, some people think it's a smart idea to do it.

I mean, it's not naughty per se, but that's a kind of solitary pleasure that you should do alone in your room, and not talk about in polite company. Programming languages are (among others) a tool for developers to communicate with each other. If you redefine the basic vocabulary before stating the most trivial thing, you're missing the most basic skill needed for any programming-related achievement.

And of all things, redefining OOP?! You know OO is largely sold as a way to improve reuse and interoperability? You realize that "custom interoperability framework" is the mother of all oxymorons? All of that because colons tickle your Java-tainted sense of aesthetic?

That's not being "the guy in the middle", that's being the forever-alone developer who'll never produce anything taking more than a couple of his individual man-months, because he doesn't understand that non-trivial development is a social activity, which requires social conventions to be learned and respected. There are many people sharing this misunderstanding, but that's a mental bug, not a feature. It should be frowned upon, not advertised.

You've transgressed your former lesbian identity, and now you're fantasizing about hetero men transgressing their hetero identity.

Moreover, penises take more and more place in your sex life: you're also exploring them in your fantasies.

Nothing surprising nor unhealthy here, I'd say.

As a member of a large teaching institution, you're naturally tempted to focus on easily tested skills. In your field, that would be memorizing sets of facts and dates. Unfortunately, the most easily tested skills are often the most boring and pointless ones to acquire (disclaimer: I've never been to a US school, so I might have minute details wrong, but I'd bet that huge public institutions work the same way all around the world).

History is interesting because it explains why our world is the way it is, so start with the interesting part. Take something contemporary, then go in anti-chronological order to its roots. Once this big picture has been given, smaller details start to make sense.

Also, listen to the history entertainer Dan Carlin and his Hardcore History podcast. He does everything right: speculation about people's state of mind, approximate analogies, anachronisms, cinematographic and pop culture references... everything you've been taught not to do as an historian, and which allows non-professionals to relate to the subject! While in front of a classroom, you're a teacher, not an historian, you're not bound by historians' rules.

I gather that you've got this SAT thing, some sort of normalized test by the end of high school, and I'd bet it tests the most boring rote memorization skills. You need to train your students for that. Be upfront with that, I have fond memories of a math teacher who did that in a comparable situation. He'd tell us "Don't worry about the maths, you'll know more than you need by the end of the year to pass. However, there are some rules to the Baccalaureat exam marking, which you'll have to comply to. I'll both teach you math and train you for the math exam, although these are mostly unrelated activities".

if the women you've been intimate with were in that category

Uh, what if women I've been intimate with just trusted me, and dared to be just themselves with me, physical and psychological imperfections included?

Successful relationships aren't about finding the perfect mate, they're about finding people whose imperfections you can cope with. If make-up is a requirement for you to be loved, you're not loved :(

TheKittenButcher · 2 months

The trick is, you can look stunning with (a reasonable amount of) moles and blemishes. Despite what "feminine" magazines would like you to believe.

TheKittenButcher · 2 months

Most guys are already informed, unless they've never been intimate enough with women to see them getting out of the shower--sisters and mother included :)

TheKittenButcher · 2 months

Fixed. I learned English mostly by doing maths, and in such a context, "discrete" is a very common word, whereas "discreet" has little use :)

TheKittenButcher · 2 months

It's even more unfair: we like girls who naturally look good without makeup.

For the many who aren't so lucky, discreet makeup is a good plan B indeed.

what about a woman who does this around other peoples' boyfriends and husbands?

You're talking about women who try to make "better offers" to men already engaged with a competitor woman. The usual way to address this risk, in economy, is to create a cartel, which excludes the "free market extremists" who think they can poach dissatisfied customers from their competitors. Such cartels are considered a bad thing by free-market apologists: they limit tensions, but they also disincentive providers from improving themselves/their offer.

In the case of women they typically threaten those promiscuous partners through slut shaming.

One might argue that being promiscuous with bachelors is not the same as doing so with engaged men. This is another way of saying that female sex providers ought to honor a non-compete agreement, i.e. form and respect a cartel. I won't enter into moral considerations, and stick with cost/benefits analysis.

There's an objective reason to go after engaged men: a great partner willing to settle in a stable relationship is a rarity, and isn't likely to remain a bachelor for long (if he wishes to settle but nobody made him a compelling offer, there must be something wrong with him, which makes him a not-so-great partner). So the best partners for risk-takers are often already in a relationship. The downside is that a poached man is more likely to be poached again, if an even better offer is made to him; but to some risk takers, or people super-confident in their value as a partner, can consider it to be an acceptable risk.

[should request absolute sexual satisfaction in exchange]

Men willing to stick with that kind of batshit crazy girl are men who have no better choice. Those in a position to negociate are our of her league.

That, or she's smocking hot besides being crazy, and she'll be fucked and promised whatever she wants to hear, until she figures out the guy doesn't even try to keep his promises.
