A commonly cited quote by Ralph Nader, states that a pound of plutonium dust spread into the atmosphere would be enough to kill 8 billion people. However, the math shows that one pound of plutonium could kill no more than 2 million people by inhalation.

So no need to worry.

Should I be learning about program memory saving techniques?
Hi,

In programming class the lecturer is always pointing out small methods to small methods so you can save yourself bytes of memory and then always goes on to say how the program will run perfectly fine regardless.

My question is to what scale do small memory saving techniques make an impact and how valuable are they even to learn?

Thanks a lot
In space, in the inner solar system, solar panels are more power dense than RTGs.

The situation might change enough being on planet where the sun is slightly filtered by the thin atmosphere, and the sun doesn't shine ~12 hours a day.

RTGs have many other advantages: they provide heat as well as power (which is really important on Mars) and they don't wear out when covered with dust. If Curiosity stops running within a decade, it won't be because of power.

Yes, the intersection of a number of curves defining regions is color-able with two colors: any point covered by an odd number of regions is black and any point covered by an even number of regions is white (i.e. a checkerboard pattern). Works as long as the boundary intersections are transverse. The proof is simply that if you cross a boundary, you must be decreasing or increasing the region count by one, changing the parity.

My sympathy goes to the writer, but honestly, if you turn up at any major sporting event, anywhere in the world, without CASH, then you are asking for trouble.

For the people that want to turn on two-factor authentication on their Gmail account, here's how to do it: http://support.google.com/accounts/bin/answer.py?hl=en&t... I highly recommend it.

Some of the common misperceptions I see:

Myth: But what if my cell phone doesn't have SMS/signal?

Reality: You can install a standalone program called Google Authenticator, so your cell phone doesn't need a signal.

Myth: Okay, but what about if my cell phone runs out of power (added: or my phone is stolen)?

Reality: You can print out a small piece of paper with 10 one-time rescue codes and put that in your wallet.

Myth: Don't I have to fiddle with an extra PIN every time I log in?

Reality: You can tell Google to trust your computer for 30 days and maybe even longer.

Myth: I heard two-factor authentication doesn't work with POP and IMAP?

Reality: You can still use two-factor authentication even with POP and IMAP. You create a special "application-specific password" that your mail client can use instead of your regular password. You can revoke application-specific passwords at any time.

Myth: Okay, but what if I want to verify how secure Google Authenticator is?

Reality: Google Authenticator is open-source: http://code.google.com/p/google-authenticator/

Hmm. Maybe I should throw this up on my blog too.
You've got the right of it. It's not a productivity tool, it's a "productivity" tool ;)

Whenever there is an argument of a CLI being suboptimal you can be sure that the counter is going to be "but it's all in my muscle memory!". CLI itself isn't efficient, it just FEELS efficient. Its real strength is the scriptability, such that repeating tasks can be substituted. If you deny yourself that power, you'd probably be better off with a GUI and good use of hotkeys.

Now, I'm aware that there are different usage scenarios. A typical developer only ever works on a handful of systems at the same time period - which makes handling your personal set of scripts a viable option. Administrators are an entirely different beast.

You're talking way past the problem that's being solved by Authenticator. If your device is physically compromised with 2-factor auth you need to change your password, end of story. There's no point in discussing how the system holds up to a scenario the system is not intended to address. Password reset is assumed if you lose your damn smartphone.

When someone steals your credit card, you just cancel the card and move on with your life. You don't call the credit card's data protection technology a failure. And changing your iCloud/Google/really any password is an orders-of-magnitude better user experience than canceling a credit card.

> It's still better than a password, but not as good as an actually secure independent factor.

Companies like Google have real, statistically significant data on how much 2-factor auth reduces account compromise. Your claims to the contrary seem to be rooted in an academic (at best) perception of weakness in the technology.
Author here. Thanks for posting this, @philfreo :)

Would love to hear feedback on the project!
There's actually one other big thing that stops the Android side from going on the offensive. The Android open-source code (like the WebM and other Google open source releases, IIRC) comes with a patent license (as it has to, or no other companies would touch it). From what I recall, that license permits you to use any patents the publisher (generally Google) owns that are required by that code as long as you don't sue anyone over patent infringement with respect to that same code. That makes going on the offensive with Android-related patents nearly impossible - anyone Google tried to sue could just integrate Android code related to the asserted patents to get a patent license, unless they already had Android-related patent infringement lawsuits going (which gets back to using patents defensively).

I guess when you go saying things like "the future of email" unless you're Google, Yahoo!, Microsoft or Facebook that's all it's ever going to be: words. From the limited glimpse I got to see of the service it looked pretty promising and very visually pleasing, but sadly without the funding ideas like this just can't and won't work.

I would like to see someone else take this idea and run with it because I think it's definitely something that is bound to happen, someone at some stage will make email better. I think the owners should open source the code on Github, it would be a shame for such a service to fall by the wayside all because the funding wasn't there.

The future of consumer computing is all mobile. Everyone realizes this. The companies that control the mobile platforms will be the biggest richest companies in the world over the next ten to twenty years. To think Google is only in the fight for its search revenues is to believe that Google is not thinking strategically long-term. In any case, if Apple ends up monopolizing the mobile platform there won't be any search revenue for Google.

Given the MSL has a constant power source does that mean it can operate 24hrs and 40 minutes a day? Do they have driving lights or can drive with IR or other sensors? If so they could get a lot more science done than the MER mission. Or do they have to channel the power into heaters each evening?

More importantly, standard procedure is also to keep multiple backup copies of important data. Because no matter who manages the infrastructure, the only reason the kill switch exists in a corporate environment is because there are scenarios where you plan to use it. Not to mention the very finite lifespan of all forms of modern mass storage, the relative ease of accidental deletion in most file systems, and so on.

Last time HN discussed this story, I said "turn on 2-factor authentication for your Google account".

Unsurprisingly, I got the exact reaction I'm seeing here when it has been suggested: lots of questions about how it works, people who think their situation is unique so it won't work for them, and people complaining than SMS is insecure.

1) Don't ask anymore questions. Try it out, if you hate it turn it off.

2) Your situation almost certainly isn't unique. You get 10 codes to print out, you can have (revokable) application-specific passwords that don't require the token. Try it!!

3) Use the smartphone application.

Don't ask any more questions - just try it out!
You actually don't. One huge aspect of this is that they remove that requirement via proxying.
Andrew Bingham, the engineer of the hazcam dust covers, explains in detail:

http://forum.nasaspaceflight.com/index.php?topic=29612.msg93...

"These dust covers were one of the last things added to the rover. The MSL HazCams are build-to-print copies of the MER HazCams. On MER, the cameras were protected inside the lander, and in over 10 rover-years on the ground they haven't seen dust building up enough to be worrysome. The Skycrane system was supposed to reduce the plume ground pressure during landing to the point where dust wouldn't be an issue for MSL."

"But after Phoenix landed and everyone saw the pictures of pebbles ON TOP OF the pads on the bottom of the lander legs, and the legs themselves coated with a sticky looking layer of dust, some concerned folks looked at the issue more closely. It turned out there is a core flow in the Mars Lander Engines on the descent stage that stays strong all the way to the surface, even hanging at the end of the skycrane. And that can kick up a lot of dust+reaction products during the skycrane maneuver, some of which would go back towards the rover. There was a review of hardware in danger of being coated with "sticky" dust; everything was determined to be dust tolerant EXCEPT the HazCams."
To reduce the risk of inconvenience, Google should really put an indicator on gmail that tells how many days left until the next authentication and allows you to renew the lease early to avoid having to pull out your phone at random. I only hope I don’t get kicked out of gmail at the most inconvenient times.
You know better than I do :)
The problem with Authenticator is that it is usually paired to a personal computer, on a personal phone (or a phone used for everything; the BYOD trend is a lot bigger with phones than computers). If your work accounts use Authenticator, even on relatively secure machines, compromising your personal laptop becomes enough to compromise the phone and thus work accounts, even if the personal laptop isn't used for those accounts. This is a bigger problem with the iPhone due to iTunes -- people pair with a machine which has a lot of music, may be used for general downloading, shared in a family, etc.

The attack can be done by pwning your personal computer, waiting for you to connect your iPhone via wifi or cable to it, and then remote-proxying the display on your phone to the attacker via the compromised personal computer. This would all be undetectable to the user.

Even a bad two factor system is better than passwords from a large service provider's perspective. Two factor using a phone isn't as secure as fully independent two factor for enterprise use.

Add to this that many high security environments don't allow phones, or that people carry only a single device (phone or maybe phone+tablet, often), and the "phone as two factor" becomes a lot less useful.

The big problem is having to carry multiple tokens, the cost of physical tokens (including replacement/management costs), and that no one makes a decent physical token at present.

iOS + some kind of "secure device-local mode" for the OS (which couldn't be remote-accessed for display, and which doesn't get pushed in backups (keystore-like), would make something like Authenticator much closer to a physical token in security.

The funny thing is WP8 actually has the tools to build this, and Enterprise (i.e. huge windows deployments with good device management) is the environment where it would be useful.

I'm sorry for the journalist who lost all of his digital information, but I think/hope that this article will have a huge impact in terms of how the security practices for all large companies with an Internet presence, will behave.

The fact that they pieced together all this information from multiple sources, including Amazon's ability to add credit cards over the phone, to getting the billing address through domain name registration, to hacking into Apple iCloud really makes me feel... I guess depressed is the word.

We really have no control over our own data security. I've been super paranoid about things like identity theft, and I got my identity stolen, which is something I've been dealing with over the past 2 years or so. Somehow, my birthdate, addresses, etc were all wrong, and I had to jump through hoops to get it changed. As well, I currently have an unpaid credit card linked to my account, and the credit agencies and the collection agency won't remove it. The collection agency required me to submit 3 copies of my signature, a police record, copies of my identification, etc, before they'll remove it, even though THEY were the ones who made the mistake. I went to the police station to file a report, but they needed documentation that I didn't have, since I had already changed most of the information through the credit agencies. At this point, I froze all my accounts through the credit agencies, and I've given up.

The safety of my email, etc, is something that I also take extremely seriously, and now I'm being told that there's a possibility of being hacked via clever hackers piecing together information from various sources, each of which have different security procedures. We literally have no data security except "security through obscurity", meaning that the likelihood of being randomly hacked is low, but if someone wants your account, they can and will get it, pretty easily it seems.

The industry NEEDS to standardize on very rigid set protocols on things like what information they give out, how accounts are reset, how things like credit cards are added to accounts, what information they leak, etc. This is ridiculous.

I'm surprised that there wasn't some kind of rangecheck for ATM deposits. I can see that you might want to take 5-figure deposits on faith and this could realistically happen, but by the time you get to 6 figures, is an ATM really where you want the deposits to be happening?
Speaking as someone who does want to buy one, I am concerned that the video didn't include any actual use. That being said, I've tried out the original Galaxy Note several times. As long as the new one is a step up in terms of responsiveness and pen performance (which seems likely, though not guaranteed) I will be more than satisfied. On the other hand, I'm also not buying one until I can try it out for myself.

What hackers don’t know about business
I remember a much less spectacular, but related 'hack' that worked here in the Netherlands until it was patched years ago. The trick was to withdraw 125 guilders from your bank account (this was before the euro), which would be presented to you as a f25,- and f100,- note. You could carefully take the f100,- note, but let the f25,- sit in the slot. After a while the ATM would detect that the money had not been taken from the slot, and take the money back. Your bank account statement would show a withdrawal of f125,-, and then a deposit of f125,- shortly after corresponding to the money being taken back by the machine.

Of course, you couldn't do this too often before they caught on to you.
I was wondering when someone would crack a Hitch-hiker's Guide reference out. Well played.

I'm not sure a physical copy actually has to exist anymore, with the Check21 regulation a digitized copy containing the relevant information is considered to be the same thing as a physical check. I don't think there's anything in the regulation that would prohibit a consumer from creating the digitized version themselves. Now getting a bank to accept it from an untrusted source (a customer) as opposed from another bank might be hard.
Oh, sure, but I still thnk striking down with great vengeance and furious anger upon those who remote-wiped your devices would be justified, even with backups. If nothing else, it costs time to restore from backup, but if you were on a trip or something and had no convenient high-speed access to backups, it would be quite unpleasant. Especially if you had, say, iPad iPhone MBA, and assumed at least one of them would be likely to survive the trip, and thus had no other local backups with you.

But yes, backups -- and not just online backups, but also offline backups.

A lot of us in Vancouver really resented the "only accepts Visa" thing. It was particularly aggravating in Canada where most people pay with a bank debit card, not Visa or Mastercard.

That said, it's not surprising that the overall effect of the sponsorship was positive since refusing MasterCard and debit was only one small aspect of Visa's campaign. Reading about this again in London made me all riled up again, but Morgan Freeman's soothing voice will likely undo the damage soon enough.
