Micron Releases 16nm-Process SSDs With Dynamic Flash Programming

AaronLS Re: Lifetime at 16nm? (22 comments)

It may not have to do with cell lifetime, but it does relate to overall endurance. If their "tricks" are legitimate algorithmic approaches to improving endurance, then the native cell lifetime becomes less of a solid metric to endurance. It would be the analogy to when clock speeds of CPUs became less relevant when manufacturers began focusing on increasing pipeline throughput instead of clock speed.

If a decrease from 20nm to 16nm feature size increases density by 25% and only decreases cell lifetime by 10%, then they will have more than enough new capacity to overprovision for the difference, and if their algorithmic improvements are legitimate, then that mitigates the need for additional over provisioning.

There's alot of "if"s in there of course, because you can't always take such PR at face value.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

AaronLS Re:Ask anyone still on Dial Up (524 comments)

So if anything 4mbps is 100 * dialup, while car is 10 * foot, so if anything 4mbps is better than a car. It's more like a mach 1 fighter jet.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

AaronLS Re:Ask anyone still on Dial Up (524 comments)

Avg. sustained running speed for a person is around 8-10 mph unless your an Olympic athlete. Car ~80 mph highway. So my anology holds as Running * 10 == Car. Just thought I'd add that for the mathematically challenged.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

AaronLS Re:Ask anyone still on Dial Up (524 comments)

"but it's still fairly frustrating"

The fact that you want to do more simultaneous "broadband activities" at a time and 4mbps doesn't provide enough bandwidth for this doesn't mean 4mbps != broadband.

You named some things it's good enough for(wikipedia requires about 5% of that bandwidth, so to imply it is just good enough is a kind of rediculous), but you've not given one concrete example of a situation where 4mbps is not enough for typical usage. Unless you're trying to download torrents while streaming 1080p from something like Netflix at the same time, then 4mbps is fine for vast majority of things. If your ISP is giving you the full 4mbps and they haven't over provisioned in your neighborhood(if your on shared bandwidth like cable) then you can have two people watching Netflix at the same time on that connection.

Those are the kinds of activities you can only do on broadband, and the fact that you can do them on 4mbps is what makes it broadband. Unless there is a problem with your connection or your trying to do more than one broadband activity, then something like Netflix should be working just fine.

AT&T Says 10Mbps Is Too Fast For "Broadband," 4Mbps Is Enough

AaronLS Re:Ask anyone still on Dial Up (524 comments)

4mbps is 100 times faster than 56 kbps. This makes 4mbps the car, and 56kbps being on foot, the bicyle would be ISDN which is about as terrible as dialup.

Math mthrfckr, learn it.

AaronLS Re:Ask anyone still on Dial Up (524 comments)

Your anology is bad. You obviously have never used dialup.
Dialup is like being on foot.
ISDN, which is slightly better than dialup is the bicycle.
4 mbps is the car.
4mbps is 100 times faster than dialup, if not more because where I can usually get the full speed of my broadband connection, I almost never got the full speed of dialup, usually around 33kbps. What took a week to download on dialup takes 1 hour on 4 mbps.

AaronLS Ask anyone still on Dial Up (524 comments)

Give anyone 4 mbps connection who is living in an area that still has dialup as their only option, and ask them if its broadband. If someone works to bring 4/1 mbps connections to more areas, they should be able to advertise it as broadband.

Scientists Sequence Coffee Genome, Ponder Genetic Modification

AaronLS Re:Le sigh.... (166 comments)

And that's where the anti-GMO nuts fall on their faces. We've eaten hybrid, selectively bred, and grafted plants for decades, and the anti-GMO's eat plenty of this stuff, and there are potential side affects to all of these processes. Just look at pure bred dogs and cats, and all the medical problems many of them have that are an attribute of their breed.

Akamai Warns: Linux Systems Infiltrated and Controlled In a DDoS Botnet

AaronLS Re: Hmmm (230 comments)

Mostly valid points. None of them invalidate the parent's point. If there is a significant infection of malware, then it is newsworthy. What factors led to the infection don't make it unnewsworthy.

"These[server systems] are easier to lock down, since there are no users downloading cool stuff and bringing in malware." Your comparing desktop usage to server usage. Regardless of Linux or Windows the same issues are there for each usage scenario.

-Desktop: If there is a vulnerability in a Linux or Windows desktop, the usage pattern of users is going to be a pathway onto the machine for malware. These days you could probably take any average user since most are unfamiliar with desktops, stick them with a desktop of any OS flavor, and they will in both cases go to a browser and do things that put the system at risk. These days they implement similar levels of security. Many flavors of both prompt you to escalate an process to root/admin privilage, so each are vulnerable to users unwisely escalating software of questionable sources.

-Server: If there is a vulnerability in a server, regardless of OS, "a remote exploit is required to bring down a server system". This doesn't invalidate the parent's point.

Parent's point is that it is newsworthy because many naive individuals in the Linux community likes to purport that Linux is somehow invulnerable to such exploits. When I say "many naive" I don't mean to say all Linux users are naive, just that there are a fair share who don't understand that Linux and software running on Linux has the same potential to harbor undiscovered vulnerabilities as any other competing OS/software.

This means they make blanket statements about how this or that security problem effecting Windows isn't a concern for Linux. They don't know about clarifying criteria that Linux is more secure under the circumstances that you maintain updates and properly administer WAN facing interfaces.

The result is you have individuals running unmaintained Linux servers because they think they are more secure, but which require significantly more attention than similar Windows counterparts. So you have two factors working against the security of Linux, misinformation, and ease of maintenance.

Even in situation where you have a capable staff who understand the importance of maintaining updates. If you have updates that are fragile and require lots of testing, require alot of babysitting to apply, or are in other ways difficult to automate in a reliable way, then you are going to occasionally create situations for admins where their manpower isn't enough to get to those updates immediately. That's not to imply that Windows updates don't sometimes break things and require testing, but I would say they are easier to automate overall and more reliable. Probably due to the fact there are far fewer flavors of Windows, so updates which do have issues are quickly hotfixed. When I've had updates on Linux fail, sometimes there is a good bit of manual work to back them out, fix whatever went wrong, and re apply them.

I am not trying to say Windows is better than Linux, as I am not trying to do a compelte comparison of the two, but simply pointing out that this article highlights some of the factors that contribute to the formation of such an infection. Certainly Windows has some of these same issues as well and we've seen infections that targeted machines that weren't up to date. However, I think Windows has done a better job at least with the automatic updates to address this kind of problem. It certainly isn't always perfect, but its pretty good.

Watch a Cat Video, Get Hacked: the Death of Clear-Text

AaronLS Re:https is useless (166 comments)

1. AC said SSL is magic, implying that they believe it is a hoax. I am simply pointing out they are an idiot who understands nothing about cryptography.
2. Saying that someone has identified a potential weakness in a cryptography algorithm doesn't change the fact that it is deterministic and well understood among cryptography experts. There is still nothing magic about it.
3. Your rebuttal implies that I was trying to claim that the NSA was innocent in some way or defend them. Obviously you have the worst reading comprehension in the history of mankind because no where in the two sentences do I make any such claim.
4. There are documents that indicate NSA was looking for potential weaknesses in various security protocols and possibly tampering with devices, but there is no evidence that they influenced the SSL standard itself to introduce weaknesses. Tampering with a device to break its implementation of SSL is seperate concept from the SSL standard itself. Could they have influenced the standard? They could be powering their headquarters with goat fetuses for all we know. It's all wild speculation in the absence of evidence. All evidence points to them pouring large amounts of manpower and computing power into breaking SSL. If they did indeed influence the standard, then whatever influence that had had no negligible effect based on what we know of the kind of efforts they've had to throw at SSL. Evidence of their efforts doesn't show any significant success. Their only successes in any relation to SSL have been more traditional techniques that involve circumventing SSL, such as compromising a server so they can capture data before it is encrypted, since SSL is such a tough nut to crack. More evidence that they haven't cracked SSL. Besides, influencing the standard in that way would have required more foresight than most governments are capable of.

Only one point is needed to show you're an idiot. The evidence is overwhelming.

Where are the Flying Cars? (Video; Part Two of Two)

AaronLS Re:As a private pilot... (66 comments)

A good car has down force and sticks to the road. A good plane does the opposite. I was at a flight museum that had a flying car on display and it was described as something like a "Mediocre car, and mediocre plane" Not that it's impossible, but the most basic attributes of a plane and car are contradictory.

How Google Map Hackers Can Destroy a Business

AaronLS Re:Wikipedia survives it (132 comments)

I think the challenge is identifying bad edits. Once you identify a bad edit, you can bulk undo everything from that source. With google maps, a phone number change might not be apparently a bad edit until you call it, and even then if it was setup with the sole purpose of misrepresenting a business, then it will be difficult to verify. With wikipedia, identifying a bad edit is usually simple as "hey this link goes to this third party place it shouldn't" or it's clear bias or vandalism.

Normal Humans Effectively Excluded From Developing Software

AaronLS Re:WTF are they talking about? (608 comments)

Indeed, no matter what language you allow people to use, from C++ to English, it comes down to communicating intent clearly and unambiguously. In just about every programming language, you have bugs resulting from a gap in what someone actually wrote, versus what they intended to write. If you don't think analytically and logically, then you are going to make this mistake alot.

On the other hand, I certainly agree that sometimes learning curves and programming hassles are steeper and more common than necessary. Poor documentation, and lack of cookbooks/guides for common scenarios, poorly communicated errors, shoddy development tooling, unintuitive tooling, etc. I hate getting pulled off onto a tangent because something isn't working as it should and having to delve into something I shouldn't have to.

Unlimited Food Stamps During System Outage

AaronLS AaronLS writes  |  about a year ago

AaronLS (1804210) writes "Electronic Benefits Transfer(EBT) card holders were allowed unlimited spending at some Walmart locations during an outage of the system that is used to determine spending limits. Some people hauling out multiple carts of groceries. According to system operator Xerox, there's an “agreed and documented process for retailers like Walmart to follow in response to EBT outage.” It is not clear whether or not Walmart followed this procedure or not, but Walmart spokesperson stated the decision was made to "contine[SIC] to accept EBT cards during the outage so that they could get food for their families.” Other retailers simply did not allow purchases during the outage. Xerox stated they would work to determine the cause and prevent future outages, but did not specifically state whether they would take steps to prevent unlimited spending during future outages.

Was this unlimited spending a flaw of the system and procedure, an intended procedure, or did Walmart simply not follow appropriate procedure? If Walmart took it upon themselves to allow unauthorized spending during the outage, why did they not at least impose a reasonable limit that would allow a family to get through the next day?

This news has already incited a lot of inflammatory and childish debate across the web from both those who are pro and anti-foodstamps, drowning out any intelligent analysis of the system/procedures that caused this event."

The HP Memristor Debate

AaronLS AaronLS writes  |  more than 2 years ago

AaronLS writes "(Note: I would have included links and appropriate formatting for quotes within the story, but I have searched and searched and found no guidelines in the FAQ or googling your site that indicate what formatting tags or HTML are valid for stories.)

There has been a debate about whether HP has or has not developed a memristor. It being something fairly different from existing technologies, and similar in many ways to a memristor, I think they felt comfortable using the term. However, there are those not happy about HP using that labeling. On the other hand, had HP created a new unique label, they would have probably gotten flack for pretending it's something new when it's not. What positive will come from the debate? Martin Reynolds sums it up nicely:

“Is Stan Williams being sloppy by calling it a ‘memristor’? Yeah, he is,” Martin Reynolds tells Wired. “Is Blaise Moutett being pedantic in saying it is not a ‘memristor’? Yeah, he is. [...] At the end of day, it doesn’t matter how it works as long as it gives us the ability to build devices with really high density storage.”"

Compromised Steam Data Included Credit Card Info

AaronLS AaronLS writes  |  more than 2 years ago

AaronLS writes "Steam has released additional information about a previous security breach, indicating that with the help of third party security experts they have determined no passwords were compromised, but billing information and credits cards were compromised. This information was encrypted, but no details were given on the level or type of this encryption, which would be significant since the attackers would have free reign to throw as much computing power at trying to decrypt the data, either through brute force guessing of the key or other means if the encryption has weaknesses. Also of significance, would be whether all the data shared the same key, or if each user's billing information was encrypted with a different key."

Flash Density Increasing w/25nm Triple Level Cells

AaronLS AaronLS writes  |  about 4 years ago

AaronLS (1804210) writes "StorageReview.com has a story indicating Intel and Micron planning production this year for Triple Level Cell flash on 25nm Lithography. This means that 3 bits instead of 2 can be stored in each cell, and the smaller 25nm Lithography generally allows more cells to be fit in the same area.
  This combination should provide a considerable improvement to the density, and hopefully cost, of flash based storage. Read more at StorageReview.com: http://www.storagereview.com/intel_and_micron_announce_25nm_triple_level_cell_nand"
