Anonymous No More: Your Coding Style Can Give You Away

Gorobei Re:Can they do it with corporate code? (218 comments)

Can they do it with corporate code where there are naming and style standards in abundance, and code reviews to ensure those guidelines are followed?

I was starting to wonder about that, then realized we at $BIGCORP are already generating ASTs from your input buffer, unifying those trees with a bunch of patterns, and telling your editor to flag questionable constructs. You type "if not foo in x" and 50ms later you get a proposed improved snippet. It's pretty rare to see quirky style in our codebase.

Bjarne Stroustrup Awarded 2015 Dahl-Nygaard Prize

Gorobei Re:Poor Alan Kay (200 comments)

"C++ is a three-way compromise between good object oriented design, backwards compatibility with C, and high performance. Stroustrup has never billed it as anything else."

Yeah, so when Bjarne wins the "sucks cocks for money with a smile, never billed it as anything else" award, we should all cheer?

Nuclear Waste Accident Costs Los Alamos Contractor $57 Million

Gorobei Re:I'd *really* better not go there (166 comments)

Oh, so it was a quote from James Conca, a nuclear power booster, not Scientific American. That's just plain dishonest.

Nuclear Waste Accident Costs Los Alamos Contractor $57 Million

" As long as you don't lick the walls, you can't get any radiation down there. "

Wow, a link to a SciAm article. Let me go read the source. Oh dear, it says absolutely nothing about licking walls. Guess that was just the submitter making stuff up.

How Amazon's Ebook Subscriptions Are Changing the Writing Industry

Gorobei Re:Rubbish (250 comments)

If the pool is greater than $0, it's a positive sum game for the authors.

If Amazon behaves economically rationally, the pool size should increase with the number of readers.

How Amazon's Ebook Subscriptions Are Changing the Writing Industry

Gorobei Rubbish (250 comments)

"Absolutely and unambiguously make writing and publishing a zero-sum game"

Um, no - the more readers, the more money. It's not zero sum at all from the writers' point of view.

Of course, back in the old days, people often curled up in a chair and read eight good books simultaneously; writers didn't compete with each other for readers' time and dollars at all.

Which Programming Language Pays the Best? Probably Python

Gorobei Re:The best reasons to learn Python (277 comments)

For the best reasons to learn Python, see The Zen of Python. If Python happens to pay more, that's just gravy.

That said, it seems hard to believe that people would get paid extra to work in such a pleasant language. If so, maybe Adam Smith had it all wrong when he said:

First, The wages of labour vary with the ease or hardship, the cleanliness or dirtiness, the honourableness or dishonourableness of the employment...The most detestable of all employments, that of public executioner, is, in proportion to the quantity of work done, better paid than any common trade whatever.

Read on a bit more. By paragraph 10 he points to increased wages for jobs requiring skill, by paragraph 20 he's getting into jobs requiring trust.

Pity he living too soon to comment on large software project laborers.

Developers, IT Still Racking Up (Mostly) High Salaries

Gorobei Re:Hold on a minute (198 comments)

Software developers help companies make more money. It is the Add in Value-Add. They are the equivalent of the machines in a machine shop. Without them, what is the point in being in business. If you are a software company you pay what you need to pay, to recruit and retain the best developers you can.

Most software developers are not in pure software development companies. They are in large companies doing something like fortune-500 stuff or selling ads (Google) or moving goods (Amazon.)

Very few companies think "let's hire more developers, they add value!" Hiring a developer is a last resort when the tech you have doesn't do what you need. It's like needing to hire a lawyer - you don't want to do it, but it's the cheapest way to achieve your goal.

How the Ancient Egyptians (Should Have) Built the Pyramids

Gorobei Re:So, is there any shred of EVIDENCE? (202 comments)

For most blocks, they just strapped four quarter-circle cradles around the stone and rolled them up earthen ramps using ropes. The remains of the ramps still exist around some pyramids, and some original cradles are on display in the Cairo museum. Pretty much considered solved by the archeologists; it's just armchair physicists who want to invent problems and propose new solutions.

States That Raised Minimum Wage See No Slow-Down In Job Growth

Gorobei Re:Crazy (778 comments)

Minimum Wage is also an attempt to keep the employer/employee relationship decent.

You could have a business model in which you maim small children so that they can earn more money while begging for you, but we, as a society, have decided that it is a bad thing. Yes, it happened in Victorian England and present day India, but we don't do it, even if it is "optimal" under free market conditions.

So, requiring you pay a person enough to live a decent live might not be that bad of an idea. If your business model can't support it, maybe you shouldn't be in that business.

Ask Slashdot: Minimum Programming Competence In Order To Get a Job?

Gorobei Re:Can't Tell Them Apart (466 comments)

I can understand that. "Take something that you do on a computer in a structured environment with constructive tools and then draw it on a whiteboard, while talking out loud, to a bunch of strangers." Impossible. Frankly, I can't write and talk at the same time, let alone try to code on the fly without a computer. I'm trying to imagine an interview for a guitarist where they say, "Why don't you walk up to a whiteboard and draw out how you'd play some song you've never heard of."

Good analogy. If you were a great guitarist, and you were looking to hire a great guitarist, that question might be reasonable. The two of you would start talking and pretty soon determine if you have a mutual fit.

Same thing with code. Maybe you think "can get the job done" is good enough. Maybe they expect symphonies, though. Right or wrong, you might not be a good fit. Heck, we expect serious CS from all our potential hires, and sometimes one stops the recruiting process because he figures we are weaker than him. Totally fair - it's not about getting the whiteboard problem right or wrong, it's about the talk between people who are going to potentially work together.

Ask Slashdot: Minimum Programming Competence In Order To Get a Job?

Gorobei Re:Can't Tell Them Apart (466 comments)

I wouldn't.

There are three basic ways to solve this problem:

1. The infinite series: some people know the basic one of the top of their heads: 4 * alternating odd fractions. Some may even know some Ramanugen (spelling - Indian math genius) better series.
2. Some people may remember there is an algorithm to compute the nth digit of Pi efficiently - ask to do a web search for the state of the art.
3. Just go to a trusted website that has already listed Pi to a bazillion digits and pluck the digit out.

Reinventing the Axe

Gorobei Try Google. (217 comments)

The axe has been with us for thousands of years, with its design changing very little during that time. After all, how much can you really alter a basic blade-and-handle?

Well, a simple Google image search for "axe catalog" shows 42 different axe heads sold by the Shapleigh company in 1929.

So, the answer would seem to be "quite a lot."

Study Rules Out Global Warming Being a Natural Fluctuation With 99% Certainty

Gorobei Re:more pseudo science (869 comments)

Which track record is that?

  • Spontaneous generation
  • Lamarckian inheritance
  • Miasma
  • Bloodletting
  • Aether
  • Java Man

Be careful putting too much faith in almighty science. They've been wrong before, you know. A lot. And people died because of it.

You show a bunch of ideas that, when exposed to science, got shot down as objectively wrong pretty quickly. Sounds like the process works.

Want to list 6 current sciency ideas that are wrong but the scientific community considers reasonable? I'll give you a few to start you off:

1. Humans are not changing the climate. Current verdict: wrong. Supporters: a few loons. Evidence: about nil.
2. Evolution is wrong. Current verdict: wrong. Supporters: a few loons. Evidence: nil.
3. Vaccines cause autism. Current verdict: wrong. Supporters: a few loons. Evidence: nil.

I'm sure Slashdot2114 will be debating the bad science ideas that existed in 2014. Some will claim history shows science is death. Smarter people will note that imbeciles, public relations people, lobbyists, and trolls have always added noise and generally slowed the dissemination of knowledge.

Where do you stand, PR Man?

Algorithm Reveals Objects Hidden Behind Other Things In Camera Phone Images

Gorobei Re:Crap (85 comments)

This is an impressive step forward in image processing - while reconstructing an image from diffuse light seemed plausible in theory, figuring out how to do it in practice is a hard problem. These guys deserve some respect.

Well, some respect, but it's hardly cutting edge or even very new. Maybe for physicists, but CS was ahead.

Kohonen described the basics of correlated reconstruction back in the 1980s.

There were videos of reading the backs of cards from diffuse lighting by the early 2000s. Admitted using some cheats like controlling the light source, but not awful compared to this paper that restricts the color.

By the late 2000s, the ideas were pretty common and computationally feasible. I even wrote a few POCs myself while working on somewhat related optical stuff.

Office Space: TV Documentary Looks At the Dreadful Open Office

Gorobei Re:I like the open plan (314 comments)

>And for what it's worth, in the last few places I've worked, the multimillionaire bosses have always sat right in the middle of the open plan with everybody else

I bet they didn't write much code.

You'd lose that bet at my workplace. The MMBs are in the middle of the open plan and are the top 1% coders: that is why they are there.

Office Space: TV Documentary Looks At the Dreadful Open Office

Gorobei Re: I like the open plan (314 comments)

That's a really good analysis. I'd add one idea: you can have more than one work location! I have my open plan desk (a massive 24 sq ft) of space where I try to spend most of my day: my direct reports are all within 20 feet, and 64 people are within "stand up and talk" distance. I also have an office for the confidential/chat stuff: we walk to it if needed. Almost all business gets done in the open: it's more transparent, we talk tech in the open, we talk strategy in the open, every direct and second level report can at least listen to what is going on and figure out if they can help.

Ask Slashdot: How Reproducible Is Arithmetic In the Cloud?

Gorobei Re:Fixed-point arithmetic (226 comments)

Exact and reproducible are very different things though., even if the former implies the latter. Also, when do you need 53 bits of precision for a standard deviation? At worst, simple scaling can keep things within the precision of a double precision floating point number.

"Exact and reproducible" are somewhat sad proxies for "accurate and precise." I once had a mathematician working for me who produced very precise standard deviations, the only problem was that the numbers were sometimes negative.
