Bananas and the sun are both radiation sources which pose little health risk to humans on Earth. Just like the radioactive isotopes detected in California.

(As opposed to humans in space, who would be in more serious danger of solar radiation.)

The reason people are trying to point that out is to help people become familiar with radiation. Familiar and intentional risks are less scary. If you want more info on that, I suggest reading Bruce Schneier's books.

That said, there are some people who have good reason to worry. For example, I'm very concerned about how long that plant worker was near the 1 Sv/hr water. I'm glad they're getting robots over there.

Thankfully, it doesn't seem to be more widespread than that. They're aware of the risks of contaminated food and are on guard. We've learned quite a bit since Chernobyl. The engineers will learn a lot here, too.

When you study engineering, the first thing they do is tell you horror stories about every major engineering disaster they can find. The Tacoma Narrows bridge video alone has probably been seen by almost every engineering student since 1941 or so.

My point is that, even if they're fighting to keep adequate containment on this plant following a worst-case scenario, the engineers won't let the same things happen again, provided they're allowed to upgrade the existing plants.

So what do you reckon, what perecentage of current nuclear power output is used to feed people? Have you researched that, or are you just making broad statements?

I did not say that we should reduce population levels, just that there are always options (like reducing population levels). It is also an entirely differnent subject if whe should aim to maximize the amount of humans living on earth (not saying we shouldn't, but I don't think we can simply assume the answer is yes, there are pros and cons).

I haven't researched this, but aren't the majority of the current 6 Billion people in regions of the earth with bad infrastructure? If so, it seems likely that they are able to survive without nuclear power, just saying. In any case I am not yet convinced by your argument. I also don't think most power is directly used for saving people's lives. It is used to power factories for building SUVs and stuff like that.

In any case, population control is probably inevitable - no matter what cures or food sources or energy sources we'll find, humans will always outgrow them.
Very interesting. Thanks for the detail. I guess the fixed GOP structure must be limited to HDV (MPEG-4). That flexibility is pretty awesome.

For what it's worth, I suspect what you describe (720p60 @ 6Mbps) is more than fine for most people. In other words, Cameron's idea that people will be going to theaters because of magical picture quality seems like wishful thinking. I suspect people go to theaters because they like going to theaters. It's social. It's big. It's immersive and (relatively) distraction-free - all part of a fun night out.

Are they going to go home to 720p60 @ 6Mbps and think 'gah!'. Unlikely.

Take doctors for example. They have to make life and death decisions on a daily basis - and that's not a metaphor. If the argument is that it imposes a psychological tax on you then I could come up with quite a few examples that are far more taxing and far less rewarding financially. Try being in a war and killing people and compare that with firing 200 people.

In most cases you go through an adjustment period, and after a while you get desensitized - or you go crazy. The same happens with CEOs, you're not going to care the same about the 200th-time you fire somebody as you did with the first.

I'm not saying is easy, or that anybody can do it, but we need to step back a little. The same way praising a child about their smarts puts them in a well-I-can't-get-any-better locked position, glorifying CEOs prevents us from critically evaluating their performance or even suggesting there's a better way... After all, we can't possibly know how hard it is.

It's also a good approach but it doesn't work for me.
For example, I started from the small set of features. When I implemented them and started adding more features I understood that the previous design doesn't fit, so I should modify it.

The main problem for me in this approach is that I haven't a complete picture of the project.

Indeed I did delete my comment :). I have been interested in the white spy / black spy aspect of semantic trading for sometime and the trust related issues. However I have no expertise in the area and no one in my network works in the area. Folks doing technology in finance usually document their work much lesser than other fields, perhaps because of the financial incentives to keep secrets. So I thought tapping the wisdom of HN was my best bet to scratch my curiosity scratch.

> Factorization is indeed in NP. It might also be in P. I should've said "based on the idea that" instead of "the fact that."

I'll reiterate. It is unknown if factorization is currently NP-hard. UKNOWN. It is most likely NOT NP-hard otherwise there would be huge implications in Complexity Theory.

It suffices for crypto for problems to be hard on an average. Factoring a random product of two large primes is hard. Factoring is probably not NP hard because no one knows if a factoring algorithm will help solve SAT.
From this paper http://info.ee.surrey.ac.uk/Personal/Z.Kalal/Publications/20... it seems that the system collects images of successful detections, and that way gets more data to base its' coming detections on.

Security can still be achieved. But it will require exponential time for an honest participant (a much lesser exponent than an adversary, but still exponential time). See: http://en.wikipedia.org/wiki/Merkle%27s_Puzzles It doesn't require P!=NP.
From Criticizing to Google’s UI Enforcement
Yes, Google's business is on the web, and they've made it their mission to make the web as fast as possible.

If the web doesn't speed up, more users will move to closed ecosystems like the iPhone App Store.

Other projects are motivated by this are Google Chrome (and the open source around it) and Google Page Speed, for example.
Replying mostly to DanielBMarkham, the sibling.

I respect your point and I mostly share the sentiment. Even so; no, da Vinci wouldn't choose what to put in the Louvre. That's the point. We chose what to put in the Louvre, and if da Vinci would have chosen another medium he would have created something else, which might not hang there or anywhere, today.

I'm doing a program where I have great use of Redis for some things, while I could use MongoDB for others. Even so, I choose to use Redis exclusively because I have a feeling that the constraint will help me create a better program.

I really believe in constraints in creation. But of course, if Cameron needs 60 fps he should shot in that!
I agree with you that it would be wonderful if all footage could be preserved with maximum spatial and temporal resolution, and maximum dynamic range (and, for that matter, some day become part of the public domain!)

All I was saying is that realistically, and unfortunately, the economic realities of film production make it unlikely that anything will be shot with quality much higher than what the stakeholders can make use of in the short to medium term.
Lets turn it around: Is there an example where speed and scalability are different?

Well, actually there are a lot of such examples. For instance consider the idea of caching data in shared memory. This is very fast. But the second you've done it with something that has to remain consistent across requests, you can't have 2 webservers any more. You're fast, but can't scale. (Don't laugh, I know of a number of websites that made this mistake at some point in their history. http://www.kuro5hin.org/ and http://slashdot.org/ are two good examples.)

Concurrency and locking issues provide lots more examples. Having fewer locks over large things is much faster than having lots of little locks. But you get less concurrency. For a toy website, MySQL with MyISAM is fine - lock whole tables. Row level locking as done in Oracle, PostgreSQL or MySQL with INNODB is much slower, but it scales.

I know that you think that this is "just another type of speed", but it really isn't. If a critical lock somewhere deep in a database is operating at 95% of maximum capacity, there is basically no visible effect on performance from the lock contention. At 101% of capacity, your database falls over. The characteristic failure mode isn't that you get slower as the request rate increases. It is that you max out your capacity and then crash if you try to go faster. I've been there, and it isn't fun.

Now with all of this said, there is a large, obvious, connection between speed and scalability. Suppose that you are comparing 2 languages, one of which runs twice as fast as the other. You can scale the slow one - just run twice as many boxes. But now you need twice as many database connections. Holding those connections open consumes resources, so you need a bigger database. And so on.

Therefore the faster environment can frequently push off the point at which you start encountering other scalability issues. But speed and scalability are not at all the same thing.
It's funny because that paper and our blog post cite the same Google paper. There's some level of interpretation of data, but some of his cited papers offer strong evidence contrary to his point.

From the Jeff Huang paper:

The mean Euclidean distance between cursor and gaze is 178px
(σ = 139px) and the median is 143px.

The problem here is that there's a long tail of completely inaccurate data: the average distance between eye and mouse is 178px. I believe there are some people who tend to follow their eyes with their mouse, and some people who don't. Google research suggests the ratio is about 1:2.

That being said, I am a bit off topic here: there is most definitely value that can be extracted from mouse position. Can it be used to tell where the user is looking? Unlikely in the common case. Can it indicate purchase intent? I wouldn't be surprised.

My rebuttal was mostly premeditated by the amount of false interpretation of research about mouse-eye correlation. There's a lot of really good research out there, but it's often mis-cited to support an opposing claim.
Now combine that with dsh (http://www.netfort.gr.jp/~dancer/software/dsh.html.en) and authorized_keys, you can _really_ get in trouble. dsh is similar to this Cluster SSH, but is appropriate for use in scripts, cron jobs, etc.

Example:

dsh -Mg all-machines -F 20 'do something'

-M: Prepend any line of output with the machine that emitted it

-g: runs the group all-machines (just a text file in etc/dsh/group)

-F 20: forks at most 20 copies of ssh in the background so you don't overload the server you're running this from

How short is the header? While 1 year+ is nice, if 1.5.x is served with, say, a 24 hour expiration header, you can still get a lot of cache benefit if the user visits other sites that use jQuery that day.
Also I'd recommend kanif:

http://taktuk.gforge.inria.fr/kanif/

This is a great tool to do mass changes to our 1200 CPU compute cluster. The best part about this is, it will map all of the hosts with the same output together and reduce this down to just one instance of the output, with the affected hostnames listed together. So instead of 500 instances of the same output data I get one. This comes in handy for finding hosts which are different than what I'm looking for.

Simple example:

--------------------------------------------------------------------------------
compute[0009,0051,0187] (3 HOSTS)
--------------------------------------------------------------------------------
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rootvg-rootlv
58G 14G 42G 25% /
--------------------------------------------------------------------------------
compute[0013,0038,0044,0046,0065,0103,0125,0142,0195,0213,0216,0234] (12 HOSTS)
--------------------------------------------------------------------------------
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rootvg-rootlv
58G 11G 44G 19% /
--------------------------------------------------------------------------------

I'm always the April Fool when I read stuff like this.
"Everything is a file" is the biggest myth of UNIX. Everthing is represented by an integer that we call a "file descriptor", that's true. But try calling "accept" on a file descriptor you made with "open", or try calling "sendfile" on a pipe instead of a socket. Doesn't work.

Everything is an integer.
It's unfortunate that he included benchmark numbers because people will discuss the numbers rather than his main point. Since we're discussing the numbers anyway, antirez, were you running Sinatra in production mode? My benchmarks on my MBP look like this:

"hello", development mode 1620 req/s
erb :index, development mode 1000 req/s
"hello", production mode 1620 req/s
erb :index, production mode 1350 req/s

I assume Sinatra is doing some kind of template reloading in dev mode which may explain the speed difference?

That said, I think antirez is right that there are lots of opportunities for making ruby faster. I'm particularly hopeful about JRuby's use of invokedynamic and all of the work that is going into Rubinius.

The thing is, once you're able to scale out horizontally then you're back to riding the Moore's Law cost curve. If my ruby app requires 4 machines now, it'll require 2 machines in two years. Should I pay the up-front cost now of writing it in something lower-level? It depends, but in lots of cases probably not.
Unfortunately, noone who was trying to answer the question, seems to know what really platform is. People like to shrug off Microsoft as an old borg who lost its way in innovation, but these guys are the ones who actually know what platform is and what does it takes to keep 20+ years of backwards compatibility and workarounds for buggy clients in the code. Spolski was complaining that Microsoft invents too much new frameworks, but the truth is that even though there're 10s new frameworks, the old ones are still there and they will work if you need to use them in your rusty old LoB application. I can hardly imagine Microsoft doing with their API the same thing Twitter or Facebook does with theirs. Platforms can't change overnight because the owner is in search for monetization, otherwise it's not a platform, but a joke.
You sure one of your friends isn't trying to freak you out on April Fools Day?

First, its not a copyright infringement its Trademark infringement, they are different. Search the USPTO trademark data base to see his clients trademark and their filing date.

If you don't believe there would be significant you can do one of two things:
1) Have an attorney respond that upon reviewing his letter you have concluded there is no basis for infringement.
2) Ignore him (although watch your mail for a certified letter notifying you if they decide to file suit.)

If on the other hand you find they have a trademark, legally registered, and that your business is apt to cause their customers confusion, then you your response will be somewhat different.

Memphis, TN - Infrastructure Engineer

We design/develop/scale an interactive mapping platform. Our early products were all about superimposing cell phone coverage for carriers on a world map for them to embed in their websites. Now we have a platform for in-browser comparative analysis of arbitrary spatial information. We currently load it up with information about the wireless, cable, and telecom industries.

I'm looking for talented engineers who can get down and dirty with optimization, configuration management, distributed systems, and architecture design. Two positions are open currently.

Stuff you'll be fooling with: Solr, HDFS, MongoDB, PostgreSQL, Chef, Ruby, Python, and C. Knowledge of Corosync/Heartbeat, ZooKeeper, AMQP, Flume/Scribe, BigTable/Dynamo inspired systems, or Scala is a plus.

No idea. I'm a programmer who happens to work at an investment bank, but finance does not interest me any more or any less than any other programming problem. The words we use to describe things are finance-related, but the problems we solve aren't.

I would personally never pay $150k for a degree, but that's because the programming world doesn't care about degrees at all. I have never tried to be a quant so I don't really know. My guess is that if you come in as a programmer on a HFT team and interest the right people, you can be a quant without any particular credentials.

I'm told by my boss that many of the people in our application support team are "blown up" traders. Which means they were traders, and now they help people reset passwords, leading me to believe that there aren't many expensive degrees required to become a trader. That's all I know, though.
That's a very valid point that I hadn't considered.

I'd be curious to see how many people use the latest vs. the specific versions. Excluding the shorter cache on latest, in theory at least, you get the greatest cache benefit from whichever is the most linked-to version, yes?

E.g., if 1.5.1 is 300% more popular than 1.5.2 at a given point in time, then you're far more likely to be primed for any given user, yes?
