Personally, I look forward to self-driving sleeper cars and a new type of motel that is little more than a secure parking lot plus some nice bathrooms. What is the feeling of "where you live" if you switch cities each time you sleep?

Also, in your hypothetical, if we are all routing calls as our day job, doesn't that mean that at any one time, 1/3 of humans are asleep, 1/3 routing calls, 1/3 possibly on calls. With at least two people per call. How can that not be workable?
You are correct that it's broken into extents, but as the extents become sparse over time without compaction, I/O gets scattered further and further around the disk.

The WAL is as much a durability features as it is about fast recovery, fast writes, and concurrency. MongoDB uses a journal collection for durability, which is quite a different thing, and actually requires doubled writes. The journal collection is just another MongoDB collection, instead of being an optimized log file structure.

The OS I/O scheduler works fairly well, but it's a general purpose tool and must work well for all types of I/O. The WAL writes themselves are ALWAYS sequential, something in-place updates will never get. The OS still tries to flush writes within something like up to 5 seconds (the Linux deadline scheduler). The RDBMS WAL checkpoint process can gather hundreds of megabytes of data over many minutes or hours, sort it, and write to the table files in a single pass.

In PostgreSQL, you can tune the checkpoint process down to how much data to write before a checkpoint, how long to wait at maximum, and how much I/O capacity to consume while checkpointing.

The cgroups, mincore, and fincore techniques are very interesting, going to look into them.

The key to the PostgreSQL strategy is that segmenting the cache into in-process buffers and the OS disk cache. It's an early warning system once the hits start to cross that threshold.

I'd be interested in learning about any strategies that could be used to segment the OS disk cache into multiple pools, because I'd prefer to actually reduce the shared buffer pool as it's somewhat less efficient than just using the OS disk cache (duplicated caches). Perhaps some kind of automated process could monitor the hit rate and actively expand the cgroups as needed to try to meet a hit rate target, and give you some warning when a RAM % threshold was exceeded.

There is nothing evil or wrong about MongoDB itself, it's just a new product that needs more polish. Many years ago when I first started using PostgreSQL, it needed much polish. It takes years and years to fine tune these types of things and find out how the initial assumptions made work out in real life.
I wasn't really thinking about driving skills, but about equipment failure. There will always be a risk of equipment failure for automated machinery. Also, there's a risk of human error in the code governing driving.

One possible workaround is to have several people at some centralized location monitor driverless car performance. A monitorer could override the car and drive the car remotely in the event of equipment failure or bugs in the code.

But, maybe that's a pipe dream.

So essentially $1100 for ~600 likes, I certainly wouldn't be happy with that return. It's an informative piece but I think your summary is a bit off regarding the campaign a success generally.

I think by simply joining Facebook groups in this sector and engaging with the group you could've achieved 600 likes in the same timescale and saved yourself the money.
Absolutely. That's essentially PBKDF2 (http://en.wikipedia.org/wiki/PBKDF2).

You usually add a salt (an additional string which is stored in the clear, but which makes your local instance globally unique, so the attacker can't precompute value to hash mappings ("Rainbow Tables" [which are faster to make if you have alien technology, from what I've heard]) for all sites.

I'd still suggest using bcrypt or scrypt.
Freenet is really slow. But you probably don't need it at all now that BitTorrent supports magnet links.

I will say to you what I say to those looking for technical co-founders: Learn to do it yourself first, until then, you trying to evaluate them is like a deaf/blind person being a judge on American Idol.

Think about it, a deaf/blind dude reading up on how to evaluate good music/dance. Or flip the problem, do you think a business guy, pure and pure, can read some stuff and then be able to judge which one of the guys on your team is the best hacker?

I know the skill set is different, but the concept is universal: you have to know a craft in order to appreciate it in order to know/tell the difference.

Well, if they've only introduced a few here and there, I suppose that's OK then. </sarcasm>

It's a good thing that's not what I said then, I suppose.

> And I personally dont support have to support ie6, but a lot of people still have to.

A few people still have to, I'm sure, but the market share has dropped like a stone over the past year or two. For most projects that aren't in-house jobs in the organisations that haven't managed to leave it behind yet, it is no longer relevant.
Really cool to see another Node framework that uses CoffeeScript. SocketStream joins the likes of:

* Brunch: http://brunchwithcoffee.com/

* Zappa: https://github.com/mauricemach/zappa

* Coffeemate: https://github.com/coffeemate/coffeemate

Of course, SocketStream's use of websockets to deliver all content (after an initial payload) is a very different, very opinionated approach. I also like the look of API namespacing, which allows client and server code to be structured analogously without having to use `requires` at the top of every file (one of Node's weaker points, as Ryan Dahl would be the first to tell you). It all sounds very well thought-out, and I can't wait to see where this framework goes from here.
Google Voice Search in French (Français)
I don't think that would be reasonable, but I also don't think that is analagous.

For starters, that hypothetical search warrant is too broad to be executed.

Keep in mind, I'm not saying that I believe that the FBI executed this seizure correctly. I'm saying that based on third-hand limited information, I don't think it's possible to rule out the possibility that what they did was warranted.

If you showed up to perform this acquisition and were able to deduce that the targets you were going after were blades in an HP chasis in a specific rack, and let's say those blades aren't identifiable within the chasis (like oh say, maybe the IP address isn't noted), it might be within reason to take the chasis and all the blades for that specific chasis.

It might also be within reason that if you can identify which specific blades are part of your acquisition, you take those, and also the chasis they are plugged into (but not the other blades, although they are now sitting on a table in a datacenter somewhere, not plugged into anything).

All we know is that customers of that same provider who were stored in the same datacenter were taken offline. Marco doesn't actually know that his blade server was physically taken, he just knows that it was brought offline.

Actually yes, I did mean cool dev tools. Sorry if that was unclear. However, I don't think Photoshop is a good counter-example since OSX has top-tier graphics applications AND runs on Linux.
a point for improvement: facebook's auction system is quite aggressive in picking its favorites. Having that many ads in one campaign, especially one with such a low daily budget, will cause one to get nearly all the impressions and take over.

You also can't stop ads after only a thousand or so impressions. Let them run for 50k+ before cutting, as an ad that performs well will take a decent amount of clicks for the bid to fully come down.

I still don't see gesture based control as the 'future of computing'. I think it can have wide applications in gaming (already does) and as this shows, presentation, or perhaps short interactions with a home control system as you walk through rooms. But as a replacement for general computer interaction I can't see it and the simple reason is: "We humans are inherently lazy and ill designed for this". Our shoulders get tired, our arms go numb, some of us do opt to stand but most of us like to sit. There is a reason that our primary input methods to date have evolved around comfortable positions with minimal amounts of movement or muscle strain and I believe the future will be the same.

Don't get me wrong, this is a VERY slick demo, kudos to the team, but as 'the future of computing', not so much. It will definitely have its uses but really I still believe that only some form of perhaps thought control, or other unimagined technique that allows us to maintain an non-fatiguing position will truly be the next paradigm shift. We're lazy that way.
One hopes that libraries are also written by a very strong team with an understanding of code correctness and techniques for ensuring it.

I thought it was clear that I agreed that C and C++ (and other memory-unsafe languages) are generally worse than other existing alternatives. I'd just like to see Stepanov's reasoning followed a bit further; maybe it will lead somewhere interesting?
It says so much about TechCrunch that they're so easily impressed by flashy crap like this. The same kind of fawning occurred over that stupid site Qwiki that reads Wikipedia to you using text-to-speech while showing a Flickr slideshow.

I was going to write up a relatively detailed SocketStream tutorial this week, but if the community would find it of benefit to see exactly how you can use CoffeeScript or/and JavaScript to create SS apps, I can add that to the pipe-line. As mentioned, it doesn't just support one of these.
> That is easy to say, and difficult to do.

No doubt. That doesn't mean it shouldn't happen.
I know, and I am glad you managed to get /something/ working because node.js is that cool. In fact, I've been working with it on my Mac and on Joyent's node cloud, but while Cygwin provides a passable experience for Linux hackers stuck on Windows, in my humble opinion it's not a passable experience for Windows hackers that want to use all of the cool dev tools that constantly spring up "over there".
When I say driverless, I'm not precluding the presence of an operator.

John Deere's iTEC Pro, for example, is capable of controlling the tractor, but still requires an operator to be in the cab, just in case. Although here's a fun video of someone who disabled the safety sensors: http://www.youtube.com/watch?v=zU4liQvrcm4

I don't know of any large operator that isn't using at least autosteer, which, for things like cultivating essentially is driverless. For what it is worth, I come from an area of grain farmers.

Yeah, I'm really sure that 50 years ago the photographer thought "F. it, if I take this picture, in 50 years some dude will be able to make a pixelated impression of it, so it's not worth my time. Oh no, wait. Copyright will protect my work from that, so I'm good to go."

The purpose of Copyright law is to "promote the Progress of Science and useful Arts", not make creators feel like they are entitled to total control over their work.

The question is whether the progress of the Arts, as a whole, is promoted by preventing people from creating derivative works. You act like copyright is all promotion, but there is of course an opposite effect, too, by preventing people from creating derivative works. Why do you think the copyright clause explicitly specifies that copyrights are "for a limited time"?
Given the nature of public transport I think we can discount the "out of my control" factor. We can even remove the human element; driverless trains are found in quite a few places and nobody is screaming in terror on them.

You're picking some bad examples for future growth. Instead, look at the problems people really want to solve.

I'd pick health care as something that's just going to keep growing. As long as people have health problems, there will be a market for attempts at solutions. As the rest of life becomes more affordable, more money can be spent on this.

Quora on MySQL failed outright when AWS EBS failed, companies on AWS using Cassandra like SimpleGeo and NetFlix did not. To their credit, Facebook were clear enough on their reasons for using HBase over MySQL and Cassandra, such as wanting to double down on their current Hadoop system/knowledge and having easily obtainable ordering guarantees on messages. It's also clear they've invested in making HBase good enough.

At large loads and footprints, imvho, Riak, Cassandra and HBase present viable options. But there are some factors to consider that don't seem to get mentioned in the pop tech press

- What are you able to operate in production?

- What are you able/willing to debug and patch?

- What hardware options do you have?

- What are your workloads?

- Which variable of C.A.P, when you lose it, most damages your business?

- Will your company's choices be evaluated in the press?

- Does your board/investors have capital tied up in business's that are using something else?

- What architecture tradeoffs and styles sit well with you?

- What kind of data access and consumption patterns make you money?

- Can you pay for help?

The right choice is context sensitive, and I'm fairly sure for this class of systems at this point in time, there's no free lunch. That means you have to do the legwork for yourself and make your own choices and commitments; doing what you heard worked for someone else is a cargo cult.
Thanks for the link. I should ask around to see who is using these.

EC2 is not always a good substitute for dedicated servers for numerous reasons, I/O performance chief among them.
Also worth noting:

The more effort the ISP's put into this initiative the more it costs them in terms of labor and upset customers. It therefore seems pretty obvious that the optimal solution for an ISP is to join the program but put in the minimum effort possible.

I predict that file-sharing tools will evolve much faster than the ISPs' half-hearted anti-piracy efforts. The result will be a lot like the RIAA lawsuits of the last few years. Occasionally someone will get unlucky, but the odds of getting caught will be so low that pirates will not be deterred to any significant degree. The only real result will be continued ill-will towards publishers, which will probably result in a net boost to piracy rates.

Here's a question that interests me. Ok, the police order you to stop filming. Maybe the law says you should follow orders, maybe it doesn't. Myabe you should, maybe you shouldn't. But what is the deal if you film a police officer performing their duty in public if they don't order you to stop?

Example: I put up a camera in front of my home that films the walk to the front door and of course it captures events transpiring on the sidewalk or street in front of my house.
I'm not home, it is filming 24/7 automatically. A police officer stops a car in front of my house. Am I breaking the law? Which one?

May a police officer enter my property, climb a ladder, and hang a flag over my camera to prevent filming them performing their duty? Why? Why not?
Heh, the concept of online clubs (with real DJ, cover charge etc) intrigues me. I wonder if that is just crazy enough to work.

Got it, thanks, though I need to be going anyway.

Yes, you need to fuzz your code, but that's not a simple process; you need to give fuzzers very complicated information about the possible problem input for your program. And there is no reason to think that your team is better at searching for vulnerabilities than a malware team; you're in a race.

Police are not elected, and they rarely attract top talent. In many cases they're not even hired and promoted by people who were directly elected. So regardless of the system of government, our law enforcement would have similar people and behave in a similar manner. It's an incredibly undesirable profession: Going into tense situations, with people who distrust you by default, for not much pay. You can easily make more doing far less, so a factor in the remaining appeal of the profession is being able to command respect. All of this has little-to-nothing to do with democracy.

I'm not defending the police here. Not in the slightest. I'm simply explaining some factors related to the state of law enforcement, and pointing out that it has a lot less to do with democracy than you think.
