Comment Re:The problem with neural networks (Score 1) 44

But then one day the neural net has a "senior moment" and drives the car off a cliff.

It's actually your geek pride that just plunged to astounding depths.

Computers don't beat humans at chess by playing human chess better than humans. They beat humans by having a deeper view of the combinations and permutations and by making very few mistakes.

A momentary "senior moment" in a self-driving car (I wish I could have rendered that in priapismic scare quotes, but Slashdot defeats me) would just as likely be followed by a Mario Andretti moment 100 ms later as it recomputes several of the box-within-box outer safety profiles ab initio with fresh camera and sensor data. It's so unlike a senior moment as to make my jaw drop (unless you count those senior moments in Quake 3 where you could momentarily see through a solid wall if your POV landed on just the right surface boundary).

You're safe then.

Comment Re:C and C++ differ dramatically in complexity (Score 5, Insightful) 52

C is a trivially simple language

You're crazy.

Back in the eighties when I was primarily a C programmer, I spent years mastering the art of writing portable C code. Our main application was required to compile under both the Microsoft and the Watcom compiler, and under the Watcom compiler we targeted both MSDOS and QNX. This was a royal PITA at times. The worst case I recall is that Microsoft had a bug in their type deduction logic for expressions that mixed signed and unsigned values. In actual fact, the Microsoft code generator used the correct rules, but the Microsoft diagnostic routine in the parser did not, causing it to issue "type conversion" warnings opposite to its own internal behaviour. Just imagine how that gave us a bad case of group-consciousness head spin until we tracked down the underlying cause.

It's terribly hard in C to defend yourself against certain kinds of accidental errors, which is one of my original reasons for moving to C++. My well-developed C programming subset (oh yes, I had a subset) was even more robust in C++. For example, in modern C++ there's much less justification for writing complex expressions using #define. Modern C++ programmers largely restrict the use of the C++ preprocessor for implementing a Turing-complete language at compile time.

Is the C99 preprocessor Turing complete?

Actually, I lied. That harmless looking C preprocessor from the dusty depths of time is but a C-hair short of being Turing complete at compile time. The smallest fiddle in the specification of token pasting might get you there.

Concerning underhandedness, the Karen Pease PIU winner would not survive having __isleap() recoded from a macro to a C++ inline function. Many of the other examples abuse the #define mechanism for encoding object lengths, rather than having the objects maintain their own lengths, such as any STL container does.

What you can foist in the unwary if you're off-scale malicious in C++ is off-scale high (it is, after all, a superset of C itself).

On the other end of the scale, if you use C++ abstractions to do good rather than evil, the never-ending refinement of the C++ language takes you to a better place, not a worse place.

Elements of Modern C++ Style

I'm not overly enamoured of Great Man theory, and likewise I'm not greatly enamoured of sanitary-conception language design, in which all the sins of the past are taken behind the woodshed and put straight en masse.

Co-existence with our dirty origins is a simple fact of human biology. It isn't true that every complexity of human evolution is automatically a turn for the worse (as you seem to imply about accrued complexity in programming language design).

The truth of the matter is that C++ used wisely can be a clean and empowering programming language, for those of us able and willing to pay the price of admission.

Whether it's reasonable to pay that price given the many other choices available now is another question. In my case, I had already paid half the price in my first professional decade as a C programmer, after stripping away the illusion that C is simple language.

I'm pretty much agnostic at this point about whether an ambitious young programmer should bother learning C++ or not, unless it happens that C++ is the only vehicle that will take you where you want to go (high abstraction level co-existing with raw hardware performance).

Too many people sit there in a state of contempt fundamentally saying "if C++ is the only viable solution, then I want a simpler problem to solve!"

Well, go to it. Fill your boots. But don't sit there and sneer at the brave souls who make the opposite choice.

Comment PC-BSD is pretty good, too (Score 4, Insightful) 103

I had never run BSD on the desktop before, but recently I converted both my desktop and my aging T500 laptop to PC-BSD. The experience has been pretty good so far.

I especially like the boot environment upgrade process. The only thing you need to be aware of is not installing new software on your system after the ZFS clone. Otherwise the upgrade process affects you not at all until you're good and ready to boot into it, and at that point if anything goes wrong, you just roll it back and wait for next time.

Then I look at my real FreeBSD server and wish it was equally slick.

My biggest problem with PC-BSD is that Life Preserver does something with SSH that's just never worked for me. I've tried multiple clients to multiple servers. I've emulated the SSH part of the connection process at the command line, no problem. But after setting up the same connection, Life Preserver bombs out with a generic (aka useless) error message.

Mostly it just works, but when it doesn't I've found some of the error messages extremely unhelpful.

(Yes, I know how to wrapper SSH to diagnose this properly, but I just haven't found the time yet.)

I've been a big supporter of the corporate death penalty for a long time. It would only be used against the worst offenders, either in severity or repetitiveness, but, it would quickly convince the other companies to shape up or be destroyed themselves.

The power of accurate observation is commonly called cynicism by those who have not got it.

Interestingly, accurate observation is precisely what one finds in short supply on the deterrent porn bandwagon.

Welcome to Duloc

If you bother to look, in real societies the death penalty doesn't actually result in a soup to nuts Dulocian run on hygienic paper.

Haters gonna hate. Do not pass Go. Do not collect $200.

Now it is true that the death penalty works extraordinarily well while the guillotine is still wet and people are all gathered in the town square (though I spy a fantastic opening here for an entrepreneurial pick pocket with an especially plush, sound-proof nutsock). At 03:00 in the dark of night two years later, with the villain hopped up on alcohol, hate, rage, and desperation it's not nearly so much top of mind as those who rarely pause to observe would like to think (well, you say, what properly motivated law enforcement agency lets a lovingly-oiled guillotine gather dust in the clink closet?)

Here's another line of implication, just for example.

Hot-headed ruffian awakes the next morning to the sound of "most wanted" posters being nailed up on every beer hall, fence post, flophouse, farmhouse, henhouse, outhouse and doghouse in the surrounding area. Then he goes to the mattress with a sawed off shotgun and a shoot-first policy toward anything that moves with the colour blue. The local authorities head off to the Kevlar vest toy store and come back clad head to toe in such a deep hue of Robocop obsidian black as so make a rural Congolese tin pot blush with envy. This solves one problem (apprehending the perp with the sawed off shotgun) but leaves the community with another problem. All those toys cost real money, and the police soon discover that acting on tips about this or that local "nuisance" helps to make ends meet at the end of fiscal.

As everyone knows, the end of fiscal concentrates the mind wonderfully.

Deterrent porn fetishists are actually pretty good at pointing out the dysfunction of the state monopoly on violence, but rarely in the same post. No—it probably doesn't happen until some post the next day.

My notes suggest that these kindred spirits function exactly like the perp who wakes up the next morning after committing his heinous crime and then worries about the consequences within the options still available.

The corporations likely to find themselves on the death penalty docket already have a bead on Senator Bedfellow's pocket book. The industrious Bedfellow was up at 05:00 and has been slaving away all day in a hot kitchen cooking up a 50 gallon drum of corporate clemency to add to his pork buffet, positively drooling over his visions of the marble-palisade beach home he'll soon enjoy.

But so what? I'm sure the deterrent-porn Wheel of Fortune will soon enough come to rest on a stout peg of propriety paint to apprise Senator Bedfellow of his just deserts, and the circle of life will remain complete, with the lusty resplendence of a Whac-a-Mole grand tour.

Do only(1) you only(2) think only(3) it only(4) happens only(5) in tech only(6)?

A professional editor at the New Yorker with decades of editing experience would struggle to formally delineate the differences in those six cases. And just this sentence is just thirteen words, just padded out with just words.

(1) As opposed to other people.
(2) As opposed to thinking other things.
(3) As opposed to vaguely posed alternate anaphors.
(4) As opposed to other places, with a potentially abstract notion of "place".
(5) as opposed to non-tech, broadly posed.
(6) as opposed to non-tech, narrowly posed.

This sentence could have been written more formally (in its narrow, intended meaning) as:

Do you think it happens in tech only(6)?

What happens, though, is that idiomatic elision interferes.

If you just blurt out: "Only in tech!" and roll your eyes, people will get your drift. Moving "only" into the dominant initial position buttresses the fragment as standing for a complete thought.

But if you blurt out: "In tech only!" people will probably go "what about tech only?" or "did you just read that off the back of the Cheetos bag?". It comes across more like a slogan than a complete thought.

But then these habits involving sentence fragments bias word order in longer constructs, and the more idiomatic and less precise word order takes habituated precedence over a word order which poses fewer cognitive burdens.

Linguists don't point this effect out nearly enough. Many weird things about short sentences are rooted in how we handle even shorter sentence fragments. For example, to write convincing dialogue, it helps if every third utterance is five words or less (efficiently laced with derision), because that's how people really talk.

Novice writers often fall into the trap of writing dialogue in a semi-formal dialect of essay-lite, in which everyone involved patiently exchanges full sentences, with never a word skipped/stomped, as if all six participants woke up that morning and inserted large, niobium-plated elocution orbs up their pompous backsides, so as to convene later on best syntactic behaviour.

In real speech in real situations (such as where there's a land grab in flight concerning the social agenda) I figure we're on BSB about 20% of the time, and those fragmentary speech patterns heavily influence how we form larger speech units that are idiomatic to even(1) the least degree.

(1) so little as the least possible; stupid, but remains customary as it pre-announces the tone of the concluding drum beat, as any good musician should.

Comment Re:Incrementing (Score 1) 285

Well, next time write:

I've pretty much trained myself to never use post-increment unless a statement is incorrect without it, and even then I'm unhappy if the statement has any other side effect at all (unless the entire idiom is lifted straight from K&R, and then I ponder why the code is rolling its own iterator loop.)

Post-increment can fail in interesting ways (yes, those darn sequence points). In addition, when using a template metaprogramming library, post-increment can trigger a large state copy that an unwary programmer doesn't expect. It can be horrifically less efficient.

On the other hand, the ternary operator (even a compound ternary operator) has FAR FEWER semantic ass-bites that plain old post-increment.

Post-increment: Visually familiar, but badly behaved.
Ternary: Visually unfamiliar (to some), but well behaved.

In the STL context, an important property of the ternary operator is that you don't have to declare the return type of the expression (whereas with an if/else assignment into an intermediate variable, you do). Maybe this is less important now with better "auto" support.

A prudent ?: will also keep you on the straight and narrow with respect to the ODR. You can avoid re-typing shared sub-expressions. Anyone ever debugged a program where consecutive lines of code intended to contain an identical subexpression, but actually didn't? No, I didn't think so.

Really, when someone complains about the ?: operator as some form of diabolical trickery, I flip the bozo bit. But you just can't get a programmer to embrace it for The Right Reasons who won't first master sequence points and the horror show of post-increment.

OS X on the Mac has FAR more chance of attracting interest from Joe Consumer than Linux does.

You would think, and then Apple decides to solder the RAM onto the Mac Mini and the Mini I can buy today configured as close to identical to my buddy's Mac Mini from several years ago (quad core i7, SSD, upgraded to 16 GB) costs half a grand CAD more today than it did then.

Because of this stupid speed bump, the small office where I'm presently working went back to Windows in a recent IT refresh after we had all pretty much convinced ourselves to make the collective jump to OS X.

Maybe we could have made the initial outlay work at 8 GB per machine instead of 16 GB (saving ourselves CAD $240 per machine) but then we would have ended up with boxes permanently capped at 8 GB.

If we were certain out company would double in size over the next two years, we could have handed the RAM-crippled Mac Minis off to junior staff and brought in another wave of less-crippled Minis at that time for the regulars.

Wouldn't it all have been so simple if we had an Apple-like certainty concerning our future staffing levels and revenue growth?

Just think, we could have used the Mini as a corporate status symbol to keep new employees in their proper place, instead of having a culture where an employee says "hey, I need to test drive all these memory heavy apps to get my work done, can we rush out and get me some fat sticks at a fair street price?" (In our shop, we tend to run beefy compute on actual servers, which is where we'll spend the money saved on the client side.)

No wait!

Using RAM-crippled hand-me-downs could have negative impact on corporate culture. I know! We'll give everyone an identical, over-speced OS X mini tower so no-one complains.

No wait, second edition!

We'll get a pickup truck full of cheap-ass used Windows 7 boxes with four memory slots each and treat them as interchangeable and disposable. Then when we're back in a revenue-positive situation, we'll take a look at the post-Skylake landscape to see whether Apple has regained its sanity.
