Ask Slashdot: Which Router Firmware For Bandwidth Management?

AaronLS Re:Pfsense (93 comments)

From the perspective of the rest of the network, the architecture of the router is pretty irrelevant, but I understand why they might want ARM but they didn't identify those reasons. I have a feeling their desire for ARM is not a direct requirement, but an indirect requirement from a desire for some of the attributes of ARM. They might find that an Intel Atom box meets the same needs. Low profile, low heat, cheap, passive heat sinks(eliminates risk of fan failure).

I went with PFSense + Intel Atom box and am happy. The web interface is pretty straightforward. Getting setup initially is a bit of a pain, attaching SSD/Card to one box and flashing, etc. Some of the documentation is terrible.

Agreed that certain scenarios are indeed poorly documented and/or pain to setup. Not that pfsense supports those scenarios poorly, but you just have to dig into command line/config editing and really have to know what you are doing.

SSD-HDD Price Gap Won't Go Away Anytime Soon

AaronLS Re:Artificially inflated cost for SSD's (241 comments)

SSDs are built off silicon chip manufacturing processes, and thus the pricing reflects that. If you look at chips such as RAM with similar feature size (e.g. 28nm) and how many chips go into an SSD, I speculate that you'd see the pricing is not that far off if comparing chips of similar feature density and size as they'd reflect the same manufacturing costs. Maybe higher for SSD, as it is a newer technology than RAM which has been around for a very long time and perhaps benefits from some efficiency of scale or other manufacturing optimizations that have developed over time.

SSD-HDD Price Gap Won't Go Away Anytime Soon

AaronLS Re:RAID? (241 comments)

Indeed, and even then for many usage patterns, latency will be much worse for the HDD RAID array, because certain operations will be the greatest latency of all the drives(i.e. if you read something striped across all the drives, and one of the drives has a longer latency in seeking to that data). So in many cases the average latency is skewed for the worst.

That doesn't even go into power/cooling savings. SSD's use 10th of the power, which is great for a laptop.

Risk of damage from bumping/moving the drive/laptop during operation is non-existant with SSD as well.

Zombie Plants Help To Spread Bacterial Pathogen

Zombie Plants Help To Spread Bacterial Pathogen

AaronLS Re:Cold/Flu makes us zombies? (38 comments)

It's an immune system response that viruses leverage to spread. If you could create a similar virus that didn't cause an immune system response, its transmition rates would probably be lower. I would argue that just as the pathogen in the article has evolved to evoke a certain response in the article, cold/flu have probably evolved to maximize the immune system response(short of killing the host) as such variations of the virus would transmit more readily and pass that evolutionary trait to other viruses.

Regardless, how is any of that a counter argument to the application of zombie terminology? Is it dead? No, then not a zombie. It's a vogue term and it's silly for a study to use the term. Modified behavior != zombie.

Zombie Plants Help To Spread Bacterial Pathogen

AaronLS Cold/Flu makes us zombies? (38 comments)

The cold/flu causes us to produce additional muccus/sneeze/cough, altering our behavior which increases transmission rates. This doesn't mean we are zombies. I think it's a very interesting find, but a little ridiculous to involve the term zombie.

.NET Native Compilation Preview Released

AaronLS Re:Thanks, but.... (217 comments)

I agree with the essence of the statement, but it's written in terms of childish absolutes such as "nobody" that obviously isn't true. Maybe if he had said "The majority of .NET developers aren't doing metro. When you expand support for this feature, then it'll be interesting to the rest of us." But some people live in a world that revolves around them and cry when they get left out. I hope this feature comes to the rest of the .NET platform, but I'm not going to cry about it.

Ask Slashdot: Do Any Development Shops Build-Test-Deploy On A Cloud Service?

AaronLS Not what cloud excels at (119 comments)

Cloud is good for reliability, scalability, and if your particular scenario meets certain criteria, sometimes cost. Overall the cloud would be usually be more expensive, but can be cheaper to use cloud and only pay for what you need if you have short periods of high load combined with long periods of little load. Thus cloud might be cheaper because rather than paying for, cooling, powering, and maintaining alot of high end servers waiting to handle a large load only occasionally, you pay for what you need with the cloud. I would speculate you wouldn't see such savings on a single server.

If you could find a development/CI hosting platform that meets your needs, that would probably be a better bet. Such a service might be using cloud behind the scenes, but they benefit from the efficiencies of scale.

Another option is a semi-dedicate VPS. There are some VPS services that give you root access and terms would allow you to use the box as you do now.

I think someone went into this with the assumption that costs would go down using cloud, but your management time is going to be the same or more. You don't have a physical box, but now you will spend more time figuring out the nuances of your cloud host.

The key is to seperate the goal from the premature jump to cloud:
-If the goal is to get rid of the physical box, then VPS is an option.
-If the goal is to get rid of the physical box and lower management time/costs, then a hosted development/build/integration service is a good option. That way you don't even have to manage the OS, updates to the software/services, or perform backups.

Man, and I was so excited they the developer iteration was 1080 resolution and only $350. If that reflects potential commercial pricing, and you look at other existing HMDs at that resolution, then that's actually pretty awesome.

Ask Slashdot: What Do You Consider Elegant Code?

AaronLS Re:Duff's Device (373 comments)

He did ask if it was a joke, which is a valid question because plenty of people on the internet make rediculously stupid statements. I don't blame him for wondering if you were serious or a joke. He clearly reallized that there was a remote possibility that you were joking, so I don't see that a "woosh" was appropriate. You could have just said you were indeed joking :)

Kodak Ends Production of Acetate Base For Photographic Film

AaronLS Re:Sensors are much better at "capturing light" (137 comments)

That's nice. I'll have to pay more attention on my next camera. Think my Nikon D60 only goes up to 1200. How is the graininess on that camera? Mine gets really grainy on long exposures if I have ISO above 800. I know that's kind of the holy grail pipe dream of getting high ISO without graininess.

Kodak Ends Production of Acetate Base For Photographic Film

AaronLS Re:Sad, but inevitable. (137 comments)

One thing is for certain, there's alot of things that are alot easier and cheaper to do in digital. I did alot of long exposures and night photography. Trying to get a balance between grainyness and being too dark is challenging when the feedback you get on your settings is a couple weeks later. You can go through a whole roll trying different settings. One time I went to pick up prints and the lab gave me the negatives and said they didn't turn out. I had to point out to them a couple shots on the negatives that were of a little bio-luminescent grub. They were skeptical but went and printed them for me and they turned out fine. That was an entire roll of film just for two pictures.

I also got alot better because I was getting immediate feedback when using manual settings.

It also makes doing timelapse photography feasible on an amateur budget.

What's really odd to me is the digital cameras are not any better at capturing light. I saw a documentary on a large telescope that talked about how much light is not captured by film, and what a huge amount more is captured by a CCD, which is important for imaging faint objects. Maybe they have a better CCD than what you get in cameras.

Computer Memory Can Be Read With a Flash of Light

LOL You don't hear the grapevine! You hear IT THROUGH the grapevine. I.e. if there were a grapevine wall and people talking on the otherside that didn't know you were there. The grapevine itself doesn't talk, it's a freaking plant!

That would be funny. A lab technician standing next to you instead of a microscope(scanning electron... whatever they use) and asking you what you see and you trying to describe it to them in words, or drawing a little picture, lol. Not trying to be mean, just a funny image to me.

Mobile Devices Will Outnumber People By 2017

AaronLS Re:Define "In Use" (130 comments)

He said "I" and "Everyone I Know". Those are some pretty specific constraints. He was making a speculation, and I see nowhere that he extrapolate that to everyone. Nor did he indicate he was an American, nor in Southern state if you're the same AC commenting below. Seems you're just as bad as far as making hostile presumptions about other people based on little to no evidence. You're entitled to your opinion, but should be embarrassed at your hypocrisy because it just demonstrates your own stupidity.

Unlimited Food Stamps During System Outage

AaronLS AaronLS writes  |  about 6 months 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  |  about a year and a half 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  |  more than 3 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"
