Spanish Judge Cites Use of Secure Email As a Potential Terrorist Indicator

ziggystarsky Re:This is obviously correct (174 comments)

In reality there no such thing as a (formal) proof. You cannot prove the simplest things.

You can prove things based on axioms and hypothesis. This works for theoretical settings like mathematics. In reality, even the most simple statement (like "This is an apple.") cannot be verified with certainty (what IS an apple?). Even if you do a DNA analysis of the genome of the object, you have uncertainty in the analysis, e.g. random misreadings of your equipment.

All you can do is be "pretty certain" about something. But that's not a proof.

Spanish Judge Cites Use of Secure Email As a Potential Terrorist Indicator

ziggystarsky This is obviously correct (174 comments)

Is it possible that using secure email services can be construed as an indicator of being a terrorist?

Take the experiment of drawing a random person. Define two events

  • T - the person is a terrorist
  • X - the person uses encrypted internet messaging

If P(T|X) (probability of the person is a terrorist given he uses encryption) is larger than P(T) (probability of the person being a terrorist using no other evidence), I'd call the fact of using encryption an indicator of being a terrorist.

Any objections?

Of course the "indication strength" might be low. But I think the fact of using encryption increases my belief in someone being a terrorist. And taken together with other observations this might be enough to take according action.

AI Experts Sign Open Letter Pledging To Protect Mankind From Machines

ziggystarsky Re:I no longer think this is an issue (258 comments)

I strongly disagree. The idea that AI will be based on logics is from the 70ies and plain wrong. If some program will develop something that can be called a conciesness, then this program will be "black box" in the sense that we built it, but have no idea how it is working. It will have goals and motivations, and maybe it will be able to find or reinterpret those goals in a non-inspectable way. Asimovs laws are also not practical because there will be no way to implement them. How would you implement these rules in a human brain?

Kawa 2.0 Supports Scheme R7RS

ziggystarsky Let's compare these advantages to Haskell (62 comments)

It combines the strengths of dynamic scripting languages (less boiler-plate, fast and easy start-up, a REPL, no required compilation step).

Let's see whether the great dynamic scripting language Haskell also fulfills these points.

  • - less boiler-plate: in addition to not requiring type annotations, Haskell even gets rid of parens; check
  • - fast and easy start-up: you can compile it to native; check
  • - REPL: check
  • - no required compilation step: if you use runhaskell it looks like interpreted, check (thouch technically that's a lie, as it is for JITed scripting languages

Now we see Haskell has all the advantages of dynamic scripting languages. How about the advantages of compiled languages?

with the strengths of traditional compiled languages (fast execution, static error detection, modularity, zero-overhead Java platform integration).

  • - fast execution: ghc creates very efficient native code, check
  • - static error detection: uhm, yes; though better than traditional languages, check
  • - modularity: dunno what this means. Since there are modules in Haskell we call it check.
  • - zero-overhead Java platform integration: unfortunately not. But since exactly when is Java-integration zero overhead?

Which proves that Haskell has all the advantages of dynamic scripting languages, and most of the advantages of traditional compiled languages.

Btw., you can do the same using any other modern compiled language. This post wants to show the "advantages of dynamic scripting languages" have nothing to do with the languages being "dynamic" or "scripting", whatever that means.

The Effect of Programming Language On Software Quality

ziggystarsky Script languages have few concurrency errors (217 comments)

See Figure 2. They even stress this in the text:

Among the dynamic languages, only Erlang is more prone to concurrency errors. The regression analysis also shows that projects written in dynamic languages like CoffeeScript, TypeScript, Ruby, and Php have fewer concurrency errors

Now everyone knows that Erlang is bs for doing concurrent stuff, right? I do all my concurrency related programming in Ruby, as every other sane developer would do!

A Mysterious Piece of Russian Space Junk Does Maneuvers

ziggystarsky Bring it down (146 comments)

Get it down now. Then you can claim you were testing technology to remove space junk from orbit. Once the Ruskies admit it's a satellite that's no longer a valid option.

Ask Slashdot: Finding a Job After Completing Computer Science Ph.D?

ziggystarsky Re:overqualified (479 comments)

I know the BS and MS students from India. If the PhDs are the same...

They appear to put enormous work into making their CV look good (like having publications in shitty journals, about shitty pseudo research). But they're not able to get anything done, because they have no skill whatsoever. Only on paper.

The Site That Teaches You To Code Well Enough To Get a Job

ziggystarsky Re:special software client (131 comments)

In particular when other sides manage to do everything within the browser. A good example is hackerrank.com. There, you can edit your code for a multitude of languages (Bash, Brainfuck, Haskell, Scala, Ocaml, Octave, R, ... just to name a few) within the browser. When you hit submit the code is compiled and run on the server.

I don't want to use a stinky client, just because these people can't code their website properly.

Linus Torvalds: 'I Still Want the Desktop'

ziggystarsky Re:I love games, but ... (727 comments)

I hate FPS games. Desperately. I love small and sometimes clever games, though. Flash games - and recently sometimes HTML5 games - are perfectly suited to my needs. Play a game for 15 minutes, sometimes 5 hours over several days - then you're done with it. You can play something completely different next time. I noticed that very often games that take only 5 minutes (like the story is over and there is no point in replaying it) get very high ratings - also from me. I love playing games with fresh ideas. And almost never a game requires to be 3D. I hate 3D games. Desperately. One series of desktop games I played was Heroes of Might and Magic. A great game. But then they decided to make the new one in 3D. For no real purpose, as the gameplay requires only 2D. Result was that you had to pan and rotate, just to get a view on your hero that was not obstructed by trees. Why in hell did they do this? 3D simply sucks.

Berlin Bans Car Service Uber

ziggystarsky Re: There's more to EU transport than cheapness (341 comments)

But the rules for commercial provision of transport service are far more stricter. Obviously adhering to these rules is connected to a cost which Uber drivers do not have to pay and thus can be cheaper.

It is somewhat sane to demand a higher level of security from drivers that are expected to transport more people. Yes, it would be very safe to demand the same level from everyone that is driving a vehicle. But demanding the higher standards only from those transporting the most people gives a good trade-off bewteen effort/cost and benefit.

In addition the insurance for an average driver can be lower, because the average number of people injured in an accident is lower. I bet (but don't know) that insurances for taxi drivers are higher. Insurance for a bus will probably be even higher.

Malaysian Passenger Plane Reportedly Shot Down Over Ukraine

ziggystarsky Re: Crime and politics in Russia (752 comments)

It is mostly limited to local criminals, ex- political leaders (Communist and "Party of Regions" parties).

In these situations I must always think about one of the leaked cables, where some embassador said that in Russia you cannot distinguish organized crime from politics.

Open-Source Hardware For Neuroscience

ziggystarsky Re:"Brain signals" (41 comments)

You noticed that the described project is used to implant electrodes into the brain of live animals (mostly rodents)? The aim is to measure an electrical signal that can be associated with a small cluster of neurons.

This indeed sounds cruel (and I think it is), and for such research the ethical cost has to be related to the scientific gain in a reasonable ratio.

Btw, I know researchers that say you can pull out the electrodes after the experiment and the animal could live on without much impediment. But the laws here in Germany demand that the animals are killed.
