Ask Slashdot: User-Friendly Firewall For a Brand-New Linux User?

ByteSlicer Re:Why? Is it really necessary? (186 comments)

I use DroidWall (iptables frontend) on my Android phone (=non-Windows) to keep apps from sending my private data out. As an added bonus, it blocks most ads.

Yes, you can choose to not install those apps, but most of them want a network connection and access to storage...

Google Project Ara Design Will Use Electro-Permanent Magnets To Lock In Modules

ByteSlicer Re:They talk very big (62 comments)

Interesting, I didn't know they have such a wide dynamic range. I knew a small rare-earth magnet near my phone would max out the Hall sensor value, but never considered recalibrating it in that state.
It's a bit difficult to test too, since it seems to use dead reckoning (accelerometer) as a fallback for rotation.

Oracle Seeking Community Feedback on Java 8 EE Plans

ByteSlicer Re:Real mature (109 comments)

So is Slashdot not capable of having any kind of informative conversation about one of the most commercially popular and long-lived everyday programming languages, because "Oracle, LOL" and "Java applets suck"?

Let's try. As a Java developer (among other things), I can say that I don't really care about Java EE (i.e. the enterprise features like JPA, EJB3).

It works for certain types of software, but in my experience, once you hit a certain complexity, you'll run into things that can't be solved with standard Java EE.

Then you'll usually drop down to the vendor implementation (JPA->Hibernate, EJB3->JBoss/Glassfish or whatever), and start using features that are not really standard.

Nowadays I just use Spring+Hibernate/JOOQ or similar frameworks for EE functionality. It requires a bit more setup work, but it allows much more flexibility when you want to do things that don't fit in the Java EE patterns. It's easier to mix and match different technologies with Spring, and you don't have to wait 5 years for an update in the standards, but you can use cutting edge technology instead.

Enterprise Java development also involves a lot of other technologies, like XML based template languages, JSON/XML web services, database queries for specific databases (JPA database transparency breaks down really quickly), JMS message broker configuration, enterprise bus configuration, web technologies (HTML, javascript, templating), etc. The Java coding part is sometimes only a small part of the whole. And you can often replace that with Scala or Groovy if you want.

I'd rather have some new core language features, like real getters/setters and the Elvis operator that was axed, those would make more difference in real life.

EU Copyright Reform: Your Input Is Needed!

ByteSlicer Re:Copyright is made out of people (154 comments)

Meanwhile, fans dislike copyright because it creates an imbalance between quality vs. convenience (cracked software is ALWAYS better) or availability (a movie or game isn't available in a certain region or is no longer sold).

That's not about copyright, that's about copy protection aka DRM. Copyright doesn't prevent the act of copying, it just provides a legal defense against it.

Ask Slashdot: What Are the Books Everyone Should Read?

ByteSlicer Re:Reasons for:SciFi list (796 comments)

Ender's Game - A great morality play; and a very exciting read.

I've read it, and liked it, but "exiting" was not the impression it left on me.
It read almost like a documentary: everything was detached, without emotion. There was no real pacing; things just happened when they had to happen.

Parents' Campaign Leads To Wi-Fi Ban In New Zealand School

ByteSlicer Re:High pitched noises (294 comments)

I wonder how much of the occasional health panic that springs up around wifi - and indeed other technologies - can actually be attributed to the high pitched hums that can be emitted by badly manufactured devices.

It may be in your case, but I don't think that's the cause in most cases. I can also hear very high pitched sounds (transformers, bats), and while they can prevent me from sleeping, they don't make me sick otherwise.

I think the more general mechanisms at work are mass hysteria and the nocebo effect (placebo's evil twin), as evidenced by this story.

"Perfect" Electron Roundness Bruises Supersymmetry

ByteSlicer Re:Invisible unicorns in a garage (150 comments)

My point was that mathematics is a science. That it is a formal science instead of a natural science is a different matter all together.

Life Could Have Evolved 15 Million Years After the Big Bang, Says Cosmologist

ByteSlicer Re:So Space Whales? (312 comments)

the surface, even though it would be frozen solid in about 6 seconds after exposure to space

Seems I read too fast and missed some crucial words. So that's more probable.
But I think it would look more like an icy explosion of gas, like a comet tail. My guess is that it would be too violent to allow a crust to form.
Of course, putting a large volume of water in space at once is a hypothetical scenario.

Life Could Have Evolved 15 Million Years After the Big Bang, Says Cosmologist

ByteSlicer Re:So Space Whales? (312 comments)

even though it would be frozen solid in about 6 seconds after exposure to space

That's Hollywood science. It would actually start boiling and freezing at the same time.
If it managed to form an icy crust, this would stabilize the pressure and stop the boiling and freezing.
If it was massive enough, the gaseous water would form an atmosphere that would also stabilize the pressure. Otherwise it would probably just boil away into space over time.
With the pressure stabilized, it would only lose heat through black body radiation, which would take a long long time to freeze it because water holds large amounts of thermal energy.

Two Supermassive Black Holes About To Embrace

ByteSlicer Re:FSVO "about" (171 comments)

The interesting thing is that the vast majority of the universe is in the "everything else" zone.... contemplate that one for a while...

Hmm, I don't think this is correct, depending on what you mean exactly.

When we talk about the universe, we usually mean the observable universe. Since we receive light from all parts of the observable universe (it's observable after all), that means we are in the future light cones of those locations (each roughly an expanding sphere in 3D+time). If we can see something, it can effect us.

But, not all of those places are in our future light cone. Because of the metric expansion of space, which causes accelerated growth of the universe, our sun's light will never reach the outer regions of the observable universe, and we will never be able to travel there unless we find some way around the restrictions of general relativity (unlikely).

Should the US Copy Switzerland and Consider a 'Maximum Wage' Ratio?

ByteSlicer Re:Huh? (1216 comments)

The voters are the ones who keep voting for status quo. If they really are desperately unhappy they should vote for something else.

Let's explain this fallacy with an illustration.
