Asteroid's DINO KILLING SPREE just bad luck – boffins

Marcelo Rodrigues
Joke

Re: Time for another big rock?

"Perhaps our ancient "Cretaceous Poultry™" will have it's revenge? Revenge is a dish best served cold...like the cold blooded reptiles(or is that over-sized chickens?) of the past."

You better pray, then, that:

1) They are gourmets

2) The world heating is true.

Then, and only then, we would be safe - as the dish would be hot...

Their loss

The Good Thing™ about the Internet is: we can always route around the problem.

Keeping this pace in a few years the rest of the world will have route that don't cross the USA. And they will be "isolated", by their own actions.

Even the content industry will get out - it will be too hard to keep track of all the "speed payments".

Dibs on the first row. And a poppcorn, please.

Google went behind our backs and really HURT US, squeal upset porn kingpins

Marcelo Rodrigues
Unhappy

"Really, if I want to jerk it to fat swedish lesbians covering themselves in butter and rolling around in a load of mud, why should anyone object to that?"

Exactly because You want it. Religion derives its power from guilty, simple as this. One incredible force drive is hysterics.

Step 1: Convince a person that $DEITY will torture him/her for all eternity, if some rules aren't followed.

Step 2: Make the rules. Be sure to make them weird, contradictory and (of course!) going against some primal instinct.

Step 3: As expected, everyone is guilty. Sell (one way or another) salvation.

Step 4: Profit.

That's the reason why sex gets so much flack. We all do it (one way or another), we all like it, and we are all born from it. It is the perfect thing to trip someone's guilt.

Google Glass gets 2GB of RAM. Think about this. Two gigs of RAM

Marcelo Rodrigues

""only 682MB of free RAM after it boots the Android OS"

So the OS to run a pair of glasses has a 300+MB footprint before it does anything useful. How depressing."

Don't forget the memory to the graphics card. It is shared, and subtracted from the 1GiB.

Same thing with mobiles. They tout the memory - but forget to say it is shared with the graphics card.

Android to drop Dalvik VM for high-performance ART in next version

Marcelo Rodrigues

Re: Strange...

"Never did work out what that extra 1 meant, the 100MHz should have implied a DX3 suffix."

IIRC, it was as follows:

"DX" -> With math coprocessor. The "SX" series didn't have one.

"4" -> Indicates a 4x multiplier. More on that later.

"100" -> The internal clock of the CPU.

So:

SX 33 -> Did not have coprocessor, had an internal clock of 33 MHz and a bus speed of 33 MHz.

DX 33 -> Had coprocessor, an internal clock of 33 MHz and a bus speed of 33 MHz.

DX 50 -> Had coprocessor, an internal clock of 50 MHz and a bus speed of 50 MHz.

DX2 50 -> Had coprocessor, an internal clock of 50 MHz and a bus speed of 25 MHz.

DX2 80 -> Had coprocessor, an internal clock of 80 MHz and a bus speed of 40 MHz.

And, the weird one: The DX4 100.

It had a coprocessor and an internal clock speed of 100 MHz. But (IIRC) you could set the multiplier at 2x, 3x or 4x. So, it could work as a DX2 100, DX3 100 or DX4 100.

I believe, although not sure, that the DX4 120 went the same way.

'World’s dumbest' suspect collared in Facebook sting

Marcelo Rodrigues

"I've educated my child to respect my belongings and those of other people.

In return, I respect her belongings and don't go moseying through her mail.

We don't need passwords in my family."

It is about containing the damage. A machine with, let's say, 3 users: One admin (with password) and two regulars.

The admin is (should be) safe from the compromise of one of the other two users. But, without passwords on the regulars, one could affect the other.

A big problem, to open your user and find everything encrypted, due to the other visit's to a bogus site...

Yes, my machine is password protected. Yes, my wife knows my password. Why not? I'm not keeping something from her - and it comes in handy, at times.

Bitcoin is MONEY, says Canada

Marcelo Rodrigues

Re: Here comes the taxman!

"Yeah... but how much money do you owe them exactly ?

Since the value of Bitcoins can fluctuate wildly there has to be a

way to determine this "value" as a certain amount of "regular money"..."

Wouldn't be easier just to tax the bitcoins? You should pay (let's say) 15% of your bitcoins profits. If you profited 400 BTC, then you should pay 400BTC x 15% = 60BTC.

Since BTC is, now, real money in Canada... buying/selling BTC for Canadian Dollars wouldn't count as "profit", would it? It should be counted as changing money. Shouldn't it?

Code Spaces goes titsup FOREVER after attacker NUKES its Amazon-hosted data

Marcelo Rodrigues

Re: Backups

"They had perfectly good backups - the backups didn't fail, someone with the authority to do so deleted them! "

The backups DID fail. An off site backup is not "backup in another machine". An off site backup is "this backup of my data would survive, even if the whole datacenter got burned down in an attack".

This is an off line backup.

They could, for the sake of argument, have used Amazon to run the business - and another cloud provider (just to stay on the cloud) to keep the off line backups. I don't know. Azure? Google? RackSpace? Don't know, don't care - as the point is: it should be in ANOTHER company, not the same. And another location, of course.

Re: "This has nothing to do with the cloud..."

"It does in the sense that an actual old-school IT server room would likely have some actual backup tapes or portable HDDs locked up in a cupboard, or trucked away to a physical (not virtual) off-site backup. When EVERYTHING is in the cloud, then it is susceptible to hackers in the cloud."

But it doesn't. Because EVERY business should have off site backups. It doesn't matter if you use the cloud, a datacenter, a colocation or your basement. Ate least ONE copy of the backups should be kept off site - and not accessible by the systems being backed up (ie: the backup can access the systems, to do a restore or a backup - but the systems can't access the backups).

Yes, the single sign on system that Amazon uses made it easier. No doubt about it. But the absence of off site backups... that was just neglect, not a cloud problem.

Yet another reason to skip commercials: Microsoft ad TURNS ON your Xbox One

Marcelo Rodrigues

"Why do the fools leave the Xbox turned on? Or doesn't it have that marvelous invention made famous by the Assyrians - an On-Off switch?"

I turn of my TV with the remote - but the pretty red LED stays on. It is in "standby", not "off". I could get up, and turn it REALLY off - with the mechanical button on its front.

But I'm lazy, and this way I don't have to remember to turn it on before use. Truth be told, my TV doesn't have mics or cameras - so it is not a concern.

Most people do the same with the Xbox - don't they?

Authorities swoop on illicit Wolverhampton SPAM FARM

Marcelo Rodrigues
Happy

Re: Can we apply this to printed bollocks as well as electronic bollocks?

"So the ICO can give a good kick in the profit margins to a company sending out 350k electronic spam messages, how come OFCOM (or somebody else) can't do the same to BT / Virgin / Sky etc for posting about the same amount of unwanted marketing material through my front door."

The reasoning, I believe, is that electronic SPAM is almost free - as in beer. When a company sends paper, there is a far greater cost - so, they tend to keep it at a minimum.

It is annoying, sure. But You don't get 500 brochures every day, selling pills to grow your... nevermind.

OTOH, I remember one convicted spammer - who got his address leaked. He received, I believe, more than a metric ton* of complains from his "customers". That was fun. :D

Samsung Galaxy S5 owners hit by fatal camera error problem

Marcelo Rodrigues

Re: first 10 days is when most fail

The difference is: The S5 are beeing replaced, aren't they? No one told the customers they pressed the camera button in a wrong way...

And it is, probably, a bad batch of cameras. A fuckup, no doubt, but hardly a fundamental flaw of the project.

And I don't even like Samsung...

Battery vendors push ultracapacitor wrappers to give Li-ions more bite

Marcelo Rodrigues

"It increases battery life for those applications that do not use the surge of power functionality ... those that do use a surge of power will of course drain the battery quicker ..."

Yes, but that's not the point. The more we demand from a battery, the more it heats itself.

Think about someone opening a site from the mobile. There will be bursts of power, when the browser process all that HTML and CSS. And there will be quieter periods, when the browser is waiting for data or the user is reading the page.

The busier periods will generate more heat in the battery, as it will deliver more energy per second. With an ultracapacitor the draw is smoothed out, with the battery providing less energy for second, in a longer time frame. This will make the battery usage more efficient, since the heat does not increases linearly with the power draw.

No, it will not help someone playing games. But will help normal usage: spikes for loading a browser, surges from scanning wireless networks and whatnot.

Boston court confirms Peeping Tom's right to upskirt

Marcelo Rodrigues

"Clearly context is important as well. Someone wearing swim wear (men and women) at the swimming pool probably have an expectation to not be ogled at. However, at the beach, perhaps the situation is different. How does one tell if a man or woman is actively looking for attention or just wants to be left alone?"

You don't have to. Respect is the key. Say you see a beautiful woman at the beach. She is wearing a very small (and provocative) swim wear. Does she want attention? I don't know - but one thing is true:

You can go talk to her. She may go along, or she may not. As long as you are respectful, she will not (or shouldn't) mind.

Now, getting close, taking out the camera and flashing her butt at point blank... that's a no-no. It's all about common sense and respect.

Frenchman eyes ocean domination with floating, mobile Bond villain lair

Re: Maginot

This is EXACTLY what bothers me. A vessel of this kind would barely follow the waves. This is great with waves of less than... 10 meters? Above this, and the wave will hit the wind turbines.

Well, we can say they are not so critical. How about a 25 meters wave? The thing is 18 meters high - and due to the hull format, will not rise with the wave. Could she stand beeing at 7 meters depth?

And, yes. 25 meters waves ARE far more common than we imagine:

Altcoins will DESTROY the IT industry and spawn an infosec NIGHTMARE

Marcelo Rodrigues

"So while ASICs are now being created for LTC, graphics cards will stay relevant for other altcoins. "

Not quite. The others altcoins (well, most of them) use Scrypt, just like Litecoin. The specialized Litecoin hardware would be quite happy to mine others Scrypt based coins.

In fact, they are MORE profitable than Litecoin. They may be unstable, they will probably die on the long run. But it doesn't matter, as we mine and sell them at once.

The site called "coinwarz" has a comparative between various altcoins, with profitability included.

Re: All that effort

"Instead of mining, crack the passwords that protect coins already mined."

There are none. Well, not in the blockchain. The blockchain is made of transaction after transaction, in such a way that the later validates the previous. One could try to break this - but he would need MORE hashpower than the rest of the network combined.

At he moment the hashrate of the Litecoin network is =~ 68,9 gigahashes. To put it in perspective: a Radeon 7970 has about 750 kilohashes of processing power. To succeed at a 51% atack, one would have to get 51% of the processing power of the ENTIRE network. That means his own machines count too.

68,9 gigahashes are about 91258 Radeons 7970. Add enough boards that this one person would have 51% of ALL. It is feasible, but hardly lucrative. Especially since the heist wouldn't go unnoticed, and either the coin would crash or the problem solved.

Bitcopocalypse! Top crypto-currency can be HIJACKED, warn boffins

Marcelo Rodrigues

Re: Electricity is free is you steal it

I am not quite sure about it. The difficulty is so great that specialized hardware is used. The smaller of them does 5 Gh (giga hashes)/s. Is uses about 10W, and is a small cube. And people use this (and its big brothers, going up to 500 Gh/s miner - the size of a big tower home PC. It is against this that a bot network would go against.

To add a little perspective: a Core i7 3930k is quoted as going as high as 66.6 Mh (mega hashes)/s. A dedicated machine, fine tuned to do mining, and doing nothing else.

Sure, 10k slave machines would do some good. But what are the odds of the infection going unnoticed, when it is gobbling 100% of the CPU power, turning the computer in a home heater?

It is not that isn't feasible. It's just that I believe is more profitable to send spam and another nasties.

Wanna sell a phone in New York? Better have a receipt

Marcelo Rodrigues

Re: Is it really that hard to ID a phone?

"... (or of the blacklists have to be synchronised, otherwise a stolen mobile could still slip on to the network)..."

Sure it is not so hard? There is no need to be real time sync: once a day would be good enough.

Every 3 hours shouldn't be hard: how many mobiles are stolen per hour - wolrdwide? 10k? 30k? Even 100k entries would be easy to syn once a day. Hell, Usenet lift a very heavier load in terms of messages/second - and has been doing it for years.

Remember: There is only need to sync the IMEI, the operator's code, the country and the time of block. What all this would amount to? 512 bytes/mobile?

New ransomware strain forces hapless users into becoming Bitcoin miners

Marcelo Rodrigues

"Locking the users out when the system is infected seems counter-productive, since they'll have to get it fixed. If the process just sat in the background taking maybe 10% of CPU, it could run for years unnoticed. 100,000 PCs all dedicating 10% of their capacity to mining bitcoins could contribute a lot of cycles..."

Yes, the same question occurred me. But wouldn' t be better to use 100% of CPU?GPU, and drop the priority all the way down? This way the malware would stand a much better chance of getting by unnoticed.

At least on desktops - where there is no battery to run flat in about... five minutes?

OK, forget the 3D telly fiasco: 4K is gonna blow you away - say tech giants

Re: 4K TVs need 4K content

"You may not want to junk your current set, but if you're in the market to buy a new tv... You will want to future proof it."

Question: When my FullHD get obsolete, will the 4k of the time be more than 1 thousand cheaper than the 4k of today? If the answer is "yes" or "it will cost exactly one thousand less", then it is better ROI to buy a FullHD today, and buy another one when the time comes.

Samsung faces Brazilian rap: Factory bods work '15hrs without break'

Re: You've got to be doing pretty badly...

"...to get in trouble breaking South American employment laws."

I don't know where You are from, but I'm Brazilian. I can tell You that our employment laws are far from abusive. In fact, there are people that calls them too protective to the employee. I will not discuss if this is accurate or not - but from the top of my head:

1) The standard work journey is of 8 hours, with one break hour in the middle to eat/rest.

2) There are limits to extra hours (2 each day).

3) The week work limit is 44 hours (monday to saturday).

And this is the tip of the iceberg. Mind You, I am not a lawyer.

CONFIRMED: Driverless cars to hit actual British roads by end of year

Marcelo Rodrigues
Happy

Re: All at once or none at all

"For example, would an automated car be able to react well to a low-to-ground obstacle suddenly falling off the back of a truck? What about a child suddenly running out in front from between two cars (thus practically invisible beforehand)? Can the car detect small but significant patches of black ice? How will it react to an accident suddenly starting in front of them? And so on?"

Well, an autonomous car is not perfect - but so aren't we!

I'm not sure about the hypothetical box hitting the road, but would bet that the car would "see" it. Simple because it must knows where the sidewalk ends - and to that it must "see" things close to ground.

The child would be, at least, treated as another obstacle. The first priority (or one of them) is not hit things. So, the car would break/swerve in order to avoid the child. If it would be successful is another argument. But i'd risk saying the child odds would be better with a computer driving the car. Simple because it doesn't panic.

About the black ice... no idea.
