Microsoft's Security Products Will Block Adware By Default Starting On July 1

marcosdumay Re:Because ... (177 comments)

Now, because they announced it beforehand, pundits will spend the next weeks complaining, loudly vociferously, obnoxiously, all the way until MS actually release it. Users will be as pissed of as in the other scenario, because despite the previous communication, they won't bother listening, and won't know about it anyway.

TCP/IP Might Have Been Secure From the Start If Not For the NSA

marcosdumay Re:Flamebait (149 comments)

It's more like: If your neighbour's house is on fire, and you don't lend him this equipment. It's not really standing in the way.

It's not also the right thing to do, but the fire seemed much smaller by the time, and you were paranoid that people would steal your equipment.

Should NASA Send Astronauts On Voluntary One-Way Missions?

marcosdumay Re:There should always be contingency plans.. (307 comments)

it has to be done with real humans or we can't know if it will succeed

Maybe I can help with some rules of thumb:

1 - If there is no breathable athmosphere, it will not succeed.
2 - If you don't produce anything to eat, it will not succeed.
3 - If there is no local manufacturing, it will not succeed.
4 - If you can not keep a rabbit, dog, rat, or whatever alive, it will not succeed.

After you do all that, yes, maybe you'll have a reason to test it with people.

P vs. NP Problem Linked To the Quantum Nature of the Universe

marcosdumay Re:Why would efficency matter? (199 comments)

On the real world, all computers operate on a finite set of possible inputs.

P vs. NP Problem Linked To the Quantum Nature of the Universe

marcosdumay Re:NP vs. P doesn't exist in the real Universe (199 comments)

A way to solve a problem is an algorithm for some kind of computer (to use the example of a previous post, a hurricane does compute the Navier-Stokes equations for a set of parameters).

The article gets crazy only when it requires that the algorithm be quick and efficient.

P vs. NP Problem Linked To the Quantum Nature of the Universe

marcosdumay Re:Are all NP-hard Problems equivalent? (199 comments)

A solution to a NP-hard problem can be used to solve any NP problem, but a NP-hard may, or may not be an NP problem. What means that no, not all NP-hard problems are equivalent (and that's for sure).

The set where all are equivalent is named "NP-complete". Those are the NP-hard problem that are also NP.

Linux 3.14 Kernel Released

marcosdumay Re:Extended compared to which older CPU? (132 comments)

Cache memory never seems to get cheaper though, not the real fast Level 1 stuff anyway...

The most important "price" for L1 cache is paid in latency. It won't become much cheaper unless transistors become arranged in 3D, and after that the game is mostly over.

Smartphone Kill-Switch Could Save Consumers $2.6 Billion

marcosdumay Re:Go to hell (218 comments)

Somehow they state that people spend 5 times more on insurance than it costs to deal with the problem... Why should I belive the numbers weren't manipulated (upwards, obviously)?

Last Week's Announcement About Gravitational Waves and Inflation May Be Wrong

marcosdumay Re:Inflation (194 comments)

In the exact sciencies, you get consensus to nearly all questions that you craft well enough to exclude any kind oppinion, but you'll get plenty of "nobody knows". You won't get any kind of consesus on the likehood of a non-mainstream theory being right, and very little on how right (or wrong) are the mainstream theories, except if you use some completely objective measurement.

In human sciences you won't have any "nobody knows" answer to those first questions. You'll have consensus on the known ones, and plenty of hand waving on the not known. You'll also get hand waving in the exact sciences, the difference is that they come after the "we don't know" part, while in the human sciences that part is missing (or maybe implicit, I don't know).

Last Week's Announcement About Gravitational Waves and Inflation May Be Wrong

marcosdumay Re:Inflation (194 comments)

You do realise that this is an article about physics, right?

Also, I don't think researchers in any area would reach a consensus if you get they all toguether.

Last Week's Announcement About Gravitational Waves and Inflation May Be Wrong

marcosdumay Re:I think more people would be interested... (194 comments)

Well, take a deep look at Inflation teories. You'll be surprized.

The kind of questions cosmologists are asking nowadays is simply amazing.

Nope, those phase changes must be after Inflation, when the Universe was already quite big.

Earth Barely Dodged Solar Blast In 2012

marcosdumay Re:ZOMG a bad thing didn't happen! (202 comments)

Yet, when anything goes wrong on the grid, they automatically disconnect themselves, with at most a few seconds of delay (while we'd have days to do that).

The only question is how much voltage does a circuit breaker support.

Big Bang's Smoking Gun Found

marcosdumay Re:Next up: a direct detection (269 comments)

Once you have a working (direct, not the one on TFA) detector for gravity waves, you just need a second one and a pair ver very well synchronized clocks. That'll let you calculate the speed of the waves.

70% of U.S. Government Spending Is Writing Checks To Individuals

marcosdumay Re:Makers and takers (676 comments)

The idea is that you pay as much as the work is worth to the worker, and charge as much as the product is worth to the customer.

If you did that, you'd have neither workers nor clients.

The $100,000 Device That Could Have Solved Missing Plane Mystery

marcosdumay Re:Does it really cost $100k? (461 comments)

There is already equipment available to guide rescue people, and they work on about any place where the passengers have hope of surviving.

Dead people don't care how long the rescue takes.

Nanomaterial May Be Future of Hard Drives

marcosdumay Re:Future of hard drives is oblivion (82 comments)

Yep, it normaly varies from a pretty big problem to a huge one, depending on the application.

But since it's application dependent, manufacturers don't even need to cite times at their specification. That's maddening.

Share of Windows computers falling

marcosdumay marcosdumay writes  |  more than 2 years ago

marcosdumay (620877) writes "PCWorld is reporting that april was a good month for Linux, between the niceties it is reporting that the share of Windows computers is falling, as evidenced by the fact that Windows sales are growing slower than PC sales and that the shares of Wikipedia browsers using Microsoft Windows (all versions) decreased from 85.63 in July 2010 to 81.78 in March of this year. In fact that share is decreasing for longer, from 89.50% at April 2009."

Free Software and Code Reuse

marcosdumay marcosdumay writes  |  about 2 years ago

By 2006 I suspected free software developers could make better use of code reuse than proprietary software developers, and with that achieve a much better productivity with time. By then I tought that time had already come, what is clearly wrong, but I've being collecting data since then, and summarized it in an article.

If anybody ever gets here (who reads those journals anyway?), you are invited to read the article.

Tracking Firefox's memory usage

marcosdumay marcosdumay writes  |  more than 8 years ago

I want to know if the memory bug of Firefox is caused by an extension, and, if so, which one. So, if you have a huge memory usage (100+MB) even after closing all the tabs but one, please leave a comment here telling your usage and which extensions you have.

Also, if you know how to easily copy the extensions list for pasting here, tell me.
