IBM targets mobile, BYOD customers with cloud software, security services
Wow - every time we the media world take a few tentative steps into the modern age, they seem to immediately scramble back into the cave of ignorance. What is it going to take for these guys to understand new and relevant business models?
> For example if you saw something with a $100,000,000 target and $0 in donations, if all you could afford was $20 would you bother to put that in?

Given that, inherent to the way kickstarter works, it wouldn't actually cost you money unless the target was met, of course I would.
Why do you want to teach your kids programming at that age?

Windows doesn't have good terminal emulator. This extension is almost like having gnome-terminal on Windows. SSH into a remote machine and you have the usual keyboard navigation that the Windows "terminal" doesn't offer.
I think the idea that something like Siri will end Google is silly. Siri is just an input-output platform for a search. I think the more likely outcome is that the best search engine will power the best Siri-like app. There's no reason why Google would miss out on being that search engine.

It is also worth noting that Google dominates mobile search even more than it does traditional search.
I appreciate the feedback. I don't think you're being snarky at all (except maybe the fast addition comment). :)

The post was meant to give a short, somewhat technical overview of the technology. It's a hard balance between too much information and too little. I'll try to elaborate at length on your points in future posts.

But here are a few short answers:

1. Transactions - These are used for updates, inserts and deletes in an RDBMS. Queries can also use MVCC which incur performance issues and fragmentation. Sky is transaction free (since events are independent) and MVCC may be a feature in the future but is not currently planned and would not be enabled by default.

2. Spacial Locality - Yes, some databases allow for clustering (e.g. Oracle Hash Clusters, Postgres has manual clustering), but Sky does it by default. Caching is built-in but prefetching hasn't been added yet.

3. Aggregation - The benchmark was just to give a baseline of data access. I don't think anyone will be impressed by the addition part. The idea was to show that there isn't a lot getting in the way (such as locks, latches, etc) when traversing data. More complex querying will obviously go slower. That being said, computing a directed graph (or funnel analysis which is similar) is a very common use case for viewing behavior.

4. Querying - The query language is essential because it means aggregation takes place where the data is. Transferring the data to a set of Hadoop servers running Java code will kill performance from sending millions of entries over the network (not to mention the network bandwidth required). The domain specific language also has natural consequences such as creating real time queries and some other cool features.

5. Comparison - I'll provide some comparison benchmarks in the future. Sky is meant to excel in performance and ease of analysis. For the specific use case of behavioral data, Sky should be significantly faster and easier to use than what's currently available. That includes Neo4j. However, that's comparing apples to oranges. Sky is built around analyzing time series data and Neo4j is built around graph data. They're two fundamentally different types of data access. Sky would fall flat on its face if you tried to use it as an OLTP or graph database.

The blog post isn't meant to talk badly about existing database technologies. I was an Oracle DBA for years and I have a huge appreciation for what relational databases can do. But most databases are meant to be general purpose. I saw that many people used tools like Hadoop to process log files because a general purpose database can't handle the load and out of that I saw a common use case that deserved its own database.

Let me know if I can address any other questions.
Semantics.

In which case, I'd encourage you to find some other way to demonstrate that value. E.g., blogging about your work. Beefing up your LinkedIn resume with testimonies from fellow engineers. Making an interesting toy project that you can publish.

If you want people to see your value, you'll have to find a way to show it to them.
The debt situation might get out of hand, but that doesn't necessarily mean we're headed for inflation. The US has gone for hundreds of years without a default[1] and I'm sort of proud of that as a US citizen, but if worst came to worst we could always just default - unlike, say, 1920s Germany.

Looks like they had a quiet policy on it from mid 2010. It didn't seem to get much fanfare until about a year later when it became common public knowledge. I guess it's possible both are lying or neither of them.

Being a URL away is a pretty big thing. Their moat includes being the default search engine for Chrome and Android devices. They've also made deals with everyone except Microsoft to be the default search engine on every browser/platform/device you can imagine.
Why? Some prof worked hard to create the starter code for many assignments so the student could focus on a few key parts. After the student completes the few key parts of the assignment it is obvious it is a derivative work of the professor.

Also posting the solution online would obviously make it difficult to use for the next year and I don't think it is productive to make a professor remake an assignment every year when the could be focusing on refining lecture content.
That is a great reason to use it as a backer, but when I said "use" I was referring to it for project creators.

I think most project creators would prefer to get the money instantly if they could do it without hurting the formula that makes kickstarter so successful. The escrow part of it being important so that customers not worry about backing a loser.
It all depends on you and your lifestyle. I know a lot of people who rarely use computers and when they do they get what they need and shut it down again. I'm guessing you (,like me,) spend most of your work day and free time on a computer. Other people go outside, play sports, build physical things, play music etc. There are many opportunities for entertainment away from a computer.

I think this is important though. I was part of the last generation that spent most of my childhood without computers (born 1990). We didn't have our first computer until I was 6 (my uncle built it as a gift for me - it ran MSDOS + had 2 games on it). Most of my time was spent outside playing sports and building things. As I got older and go my first games console (N64) I spent more time using computers but most of it was still spent outside.

When I look at my younger family members who have grown up with the internet it surprises me how little time they spend outside. When they visit friends they play games on the computer. Being 'grounded' and not allowed out is no longer a punishment. Being made to go out and not use the computer is.

I think it will be very interesting to look back 50 years from now and see how much of an impact this has on peoples' development. Will people born with computers evolve significantly differently from those born without them?
It's important to note that the main reason the graphs do not show inflation is b/c of the massive housing crash.

We have a situation where we have significant inflation in some sectors of the economy, but we also have enough deflation to offset it. I'm not talking about bad deflation, I'm talking about new advances in microchips, etc., that make computers cheaper and more powerful every year.

Inflation and deflation are natural aspects of a dynamic economy. The thing to watch for is when they signal structural problems. If microchips increased in performance so quickly that vendors refused to order inventory and store shelves were empty, then it would be a structural concern. Policymakers find it useful to wave the very imprecise notion "deflation" in front of the public without bothering to mention that it's all due to technological advancement, automation, outsourcing, etc.

Similarly, inflation isn't always bad -- developer salaries are "inflating" now, which sends a signal for more people to learn to write code. This will be self-correcting. The thing to be concerned about is when government action causes inflation sufficient to undermine peoples' willingness to accept the currency.

Policymakers try to get away with doing as much micro-tweaking as they can with the economy. Tax breaks for one select group of people, subsidies for another, etc. These sorts of policies can, over time, create inflation that is not self-correcting, since the policies are rarely ended once they have been created. Consider the massive over-investment in real-estate fueled by tax breaks. This led to an unstable real-estate market that crashed hard a few years ago.
Windows! I spend most of my time coding in PuTTy + Vim when I'm on windows. In my limited testing this works as I expect with xterm-256, tmux, and Vim on my Ubuntu 12.04 Server without having to configure anything. PuTTy is a pain to configure on a new box.
I'm concerned about individual rights too. In fact, it's my concern for individual rights that leads me to reject overly restrictive copyright, (among other things). I find these rights to be valuable: freedom of speech, freedom of creativity, and property rights. (To be clear, by property, I do not include imaginary property like copyright.)

Why shouldn't I be able to make back-up copies of the DVDs that are bought with good money? Why should the descendants of Tolkien be able to censor any works of art that includes hobbits? Why should Time Warner be able to censor me from singing happy birthday in public? Why should Google be blocked from bringing out-of-print books to the public? Once a work is published, I don't see why an author should be able to control what's no longer theirs, any more that I would expect a plumber to dictate what I'm allowed to do with the plumbing in my house. Both plumbers and artists labour, and they deserve rewards for their labour, but they do not deserve the right to control my use of what I have purchased from them.

For me, the right of sharing culture is a given, and the right to restrict other people from sharing culture is at best a necessary evil.

Good catch. But where's productivity been going?

So while this indicates an assumption that should be identified and recognized, the correction doesn't impact the conclusion in this case.

Have you heard of iCloud? Apple is already there. You are just confusing networked apps, data in the cloud and web apps. Native apps can have all that and still offer superior user experience. They will always have that advantage—no matter how fast the browsers get they will still be a middle man.
Correlation does not equal causation. Brazil has a lot of features which differentiate it from countries like the US and UK. Picking two and simply assuming one must be caused by the other is a gross nonsequitur. Brazil also has a much stronger culture of birth control, and has experienced a lot more social and political churn in its recent history. I'd look to either of those as plausible contributing factors before fixating on negative stereotypes.
It fired for two seconds. There really wasn't going to be much to it anyway, unless something went tragically wrong.

Still nice to see them proceeding through all the hoops, though.
Does Technology Support The Rise A Totalitarian Elite

Why? If I search, say, for a game review, I don't care whether it comes from a popular website or a blog no one reads. In fact, the topmost websites are more likely to be biased, since they try to appease everyone and they also have strong relationships with publishers. The blog no one reads is nearly guaranteed to be honest (if not well-written).

This holds true for most topics I can think of. Moreover, if I ever need to read Wikipedia and such, I already know about those websites, and I can go there directly - no need to search. Shouldn't web search engines act like discovery tools?
This is a wildly impressive syndicate. But looking down this list (that even includes Hollywood/entertainment elite: Ari Emmanuel, Ashton Kutcher, Micheal Rapino) I couldn't help but wonder: Will managing the amount of ego on this list be a 25-hour-a-day job on it's own?

Given the scope of the names on that list - and the industries they're representing - there could easily be some conflicting interests and competing agendas within the group. Also, a ton of alpha a-players who may or may not be domesticated for this type of "super group". Could this much mojo be counter-productive?

I wish Socialcam the best, and hope this doesn't end among the graveyard of "Why Dream Teams Fail" case studies.

theory of the dream team is wrong. You cannot assemble a group of
stars and then sit back to watch them conquer the world. You can't
even count on them to avoid embarrassment. The 2004 U.S. Olympic
basketball team consisted entirely of NBA stars; it finished third
and lost to Lithuania.

What still mystifies me is how large grocery stores, like Safeway, Albertson's, Kroger, etc can afford to pay 100% medical care for their employees. I was a Safeway employee (and begrudging UFCW member) from 1998-2007, and received 100% paid for medical, dental, vision, and other care merely for working more than 20 hours a month. For family care, employees merely must work more than 30 hours a month.

6 years ago, Safeway's CEO announced they would be requiring preventative care and physicals to cut medical costs: http://www.yalemedlaw.com/2008/11/the-safeway-effect/

After completing college, I've found that the 4 companies I've worked for (mid-level IT for fortune 50 financial/tech companies) claimed they couldn't afford to pay for any medical care. Instead, they reminded us how much compensation they were already providing.

Why are grocery stores able to pay for this when nobody else will?
Heh - probably. But I'm far too self-conscious to have a real blog for people to read, especially considering how harshly I judge other people based on their blogs... and think how it makes them look like arrogant pricks who I'd never want to work for.

Forget the word inflation -- it is too politically charged and people think it means all kinds of different things.

However, in the long run there is little doubt that an expansion of the money supply will cause a rise in the price of goods and services.

Forget fancy metrics like NGDP and consider this thought experiment: if all of a sudden magically everyone's bank account balance had the decimal point moved to the right one place, what would happen to prices? After a very short transient period, they would increase by about a factor of 10. This is exactly what is happening right now (on a smaller scale and the magic occurs in the treasury department). The difference is that the extra money has been created, but is not really in circulation. Once banks and companies feel they no longer need the money in their accounts and can begin to put it into the general economy, prices will rise. Sure, the fed could take action to take money out of circulation as companies release it into circulation, but that is too politically unpopular and won't happen.
It is easy. Fire one 40 hours worker. Hire thirty-nine 1 hour workers. Congratulations! You've increased your "labor force" by 3800% !!!

You have a net loss of 1 man-hour however. I'm not totally sure how this relates to inflation, but jobs absolute numbers and gdp are only slightly related.

Another example would be to fire everyone making more than 100k$/year and relocate them to potato farming. In terms of gdp, this would be a net decrease despite the absolute worker count remaining the same

Flagged. Why are we citing a tabloid with a known history for making up stories as an authoritative source for technology news?
Based on my experience, and measurements I've made over the years, I would say that one or both of two things happened:

1) You triggered the voting ring detection code, and/or

2) You got several downvotes.

I do feel that there is a sizeable collection of people here on HN who, for whatever reason, don't like discussions about philosophy of consciousness and similar. If you get 10 or so downvotes and only 10 or so upvotes, your item will sink to the 1000s. I have seen it happen. (based on surmise about flags - they are not explicitly visible.)

This discussion happened recently: https://news.ycombinator.com/item?id=3890565

The item was flagged dead, but the discussion is still there.

HN remains a remarkably civil forum, and perhaps the occasional apparently draconian measures are part of the price to pay.
For an enthusiast, it may not be clear exactly what "Static Fire" means. While Static means non-moving, it also means the hissing noise on mis-tuned analog connections, and it's not inconceivable that it has another overloaded meaning.

Good for Apple. They're doing what any rational person or company should do - move business to where taxes are lowest. States like California and Illinois are doing their best to drive out business (and jobs).
It seems to me that the most appropriate role for domain experts (including computer science) is anticipating results in that domain. For example, my primary objection to SOPA was not the original justification for the law, but merely the likelihood of unintended consequences and broadening of the law beyond reasonableness. The ramifications of a law on a technical domain (like DNS, say) seem more appropriate for expert commentators.

Yup. Since this is trivial for Google to copy, it's unlikely that it'll actually disrupt Google in any way, but still...very cool.

Brutal truth is the right way for me, a lone founder, freelancing and struggling to find time to push the startup forward.

I've tried a lot of things to stay productive (1), and I've learned I can't control my motivation, but I can pick some low-hanging fruit to get me back into it.

Project Persistence started today, with the idea being to work at least an extra hour on pushing non-freelance goals forward and not breaking the chain. Hard without a physical calendar to cross off the days, but I prefer to try without to build a new habit.

The Hot Startup Destination You Didn't Know About
You got me really excited, but I don't think this is what I want. Imagine a table "Chapter" with a Foreign Key "Book". Not uncommon would be to have a 'sequence' or 'rank' column in the Chapter table defining it's order within a book. Sequences shouldn't overlap (accomplishable with a unique constraint on sequence and book_id), but they also shouldn't have gaps, and it'd be nice if inserting a Chapter at a sequence had predictable behavior (like.. it incremented all chapters in that book with sequence >= it's).

I find it a pretty typical and profound source of frustration, and since the whole idea of RDBMS is to model relationships.. and relationships so often have integral sequence/rank.. it's always seemed to me like something that ought to've be considered 'in scope' during the design of SQL.
