In the ideal case, sure.

However, according the HTTP archive websites make about ~90 requests per page [1]. The average browser does about 6 requests per hostname, and 15-20 total [2]. In this situation, our critical path has at least 4 requests, thus we are paying 4xRTT in just latency.

Porting to Linux because the other operating systems are getting centralized software management. I never thought I would see the day.
To my reading the guidelines didn't apply given what I knew at the time. As far as I knew the problem might have been purely local, in which case I didn't want to hassle YC/PG with what would amount to a support issue. I thought it prudent to try to discover if it was wider than just my situation. So I posted.

If you honestly can't see the difference between posting to tell YC/PG about a problem, or to ask them a question, as opposed to posting to ask if other people are having the same problem, then I'm at a loss.

If one ever looks at the various OEM firmwares, they're all ridiculously huge even for just being compressed images when comparing to vanilla Android. HTC is also similar in bloat, but just giving the S3 comparison since it was handy and related to the topic:

Not full time consultants, and being a consultant to a startup is way different.

1. They are already doing it for the YC funded firms.
2. Unlike real consultants, they can build startups, fund startups, get involved more.
3. YC has lot of traction for this, I feel a good idea is being overlooked.

Unfortunate if true, and just as futile as "attached magazine" laws.

I don't know about not being able to install apps on microSD at all, but as a Gingerbread user, I find an awful lot of apps simply refuse to install on the SD card and must use the internal memory, which sucks, considering there is very little of it on my budget Samsung phone.
Well, people price things at the price they want to sell them for, not the price that people will buy them for. Many players fail to grasp the concept that an item's value is whatever someone will pay for it, and not a copper more.
I wonder if your hiring process isn't more narrow and exclusionary of independent learners than you think. It is really quite easy in 2013 to have racked up 8 years of real high-quality development experience without having any idea how memory allocation works at a detailed level. For some portion of the people with 8 years experience it will be easy for them to go and independently figure out how it works and for others it won't. You want people in the first group, but you can't find them just by asking them questions about memory allocation.

(Also, do you do something having to do specifically with memory allocation or is it just your pet entry on the list of things you think everybody should know about to not be dumb?)

Actually, in the past that paper and the presses were hard to get undetectably. This is changing as more and more of the world achieves higher levels of industrial infrastructure.
wow, even more wild claims without providing sources.

I lived in communistic country, trust me workers were exploited much more in the communism than in capitalism. They had to work for free in gulags (slave labor), they had to work overtime (i.e. 16 hour shifts), the child labor was common. And any complaints regarding this were equaled to anti-communistic act of treason and punished with jail time. Ever heard of Dear Leader and North Korea?

I think you got it backwards. You really did. The revolution of workers against the communistic rule is ultimately this what destroyed communism in the Eastern Block. Solidarnosc was a trading union fighting against communism. If communism was so great for workers why they were the ones who lead the revolution against it in places like Poland?

Communism is much more worker unfriendly system than capitalism. So, yep, you got it opposite. There were workers revolutions against communism and not capitalism.

But because communism is a religion, you won't listen to these arguments based by facts in recent history, you'll keep mumbling about Marx, so I'll leave you with that. It's like trying to explain to a Catholic that a virgin can't give a birth to a child.

Show HN: Chrome extension for interactive in-app training inside Google Apps
I try to stay focused by creating a personal syllabus for each subject I'm interested in. I add books to them, as well as objectives and questions I'd like to answer. Of particular value has been the habit of setting written products as my objectives. These help me focus on important aspects of a subject as well as help weed out irrelevant reading material.

I use a simple sequential filing system for articles. I assign incoming articles a serial number. I have a file that allows me to browse these by subject and author, but the serial number makes them easy to reference when I want them.
Similar used to (and I assume still does) happen fairly often in FFXI as well, thanks to the Auction House system, where someone "corners" the market for a short period by buying up the entire stock and then placing them back, incrementally marking up the price. But by driving up the price, it'd attract more sellers and good ol' supply & demand would correct the price back down.

HTC One doesn't have a replaceable battery and has no microsd slot. That alone makes the S4 better for me.
There have been many prison guns made from a piece of wood with a slot cut in it. That's enough to keep the case from splitting enough of the time on a low powered round to be useful.
It's related because it's another example of discovering a local symptom and attempting some investigation before emailing YC/PG.

I attempted an analogous investigation before posting. I tried Private Browsing mode, which worked. I tried different browsers, which didn't. The next step in my investigation before emailing YC/PG was to find out if it was just me on this local network, and the only way I had to investigate that was to ask someone else. The only way I could do that was to post to HN. It seemed the obvious next investigatory stage.
There's at least one good reason for Dynamo's write-to-all and read-from-all mechanism: latency.

What you've called 'W=2' in Couchbase is "write to master and at least one slave." Dynamo-style 'W=2' means "write to any two replicas." This can decrease tail latencies since you don't have to wait for the master--any two will do; similarly for 'R=2'. Indeed, Dynamo 'W=2, R=2' will incur more read load than master-based reads (at least double, but not necessarily triple, in your figures). So I think it's more accurately a trade-off between latency and server load.

There can be big benefits to this redundant work. For example: http://www.bailis.org/blog/doing-redundant-work-to-speed-up-...

But don't take it from me: http://cacm.acm.org/magazines/2013/2/160173-the-tail-at-scal...

Anyway, I'm pretty sure CASSANDRA-4705 (https://issues.apache.org/jira/browse/CASSANDRA-4705), which allows for Dean-style redundant requests, both decreases the read load (at least from the factor of N in your post) and should still reduce tail latency without compromising on semantics.

I don't have skin in this game, but I'm pretty sure that the Dynamo engineers had a good idea of what they were doing. (That said, the regular [non-linearizable] semantics for R+W>N are sort of annoying compared to a master-slave system, but can be fixed with write-backs.)

Honest question: what field are you in which means your candidates are going to need to write custom allocators on a regular basis?

What problems need custom allocators? I'm a fan of lower level details and all, but surely you can get away with one of the many existing allocator implementations when the problem to be solved isn't "sudo make me an allocator"?
It could explain why we haven't encountered aliens despite the advanced age of the Earth. The Earth has been around for roughly 1/3rd the age of the universe, but because space time is expanding exponentially, only a fraction of the universe (roughly 20%) is theoretically reachable, even when travelling at the speed of light. A planet like Earth that formed around the same time, or earlier, even relatively close to the Earth, may now be in the unreachable zone. By the same token, the longer it takes for an intelligent species to evolve, the less likely it is that they will ever be able to contact us.
Unless I'm misunderstanding what's being described here, I believe they were kept up through 10.6. I'm running 10.6.8 currently, and there are two scroll buttons at the same end of the scroll bars, as in NeXT. But from 10.7 the scroll buttons were scrapped entirely.
I'm not sure about how the S4 is doing, but there are already CM builds for the One. Plus, it's super easy to unlock the bootloader by just going to htcdev.com (though not if you have an AT&T phone, I believe). To unlock the S4 you have to rely on hacks.
If you want to take Tesla as an example for how to start a brand new car company:

1) Spend 6 years at an insanely high burn rate with zero revenue for research and development to create a marketable car

2) Have enough brand loyalty to delay delivery to your high-earning clientele multiple times

3) Hustle Daimler into investing to do payroll at the height of the financial crisis, with Daimler themselves having no money

4) Hustle the DOE into funding your fully electric sedan while having only a taped together basic model to show for it, with your competition (Toyota) being granted billions just to refit a factory
> Why has the economy been created in the first place? As an end in itself? Or was it to make life easier for everybody?

Economies are not created in any traditional sense (though ours is highly managed, for better or for worse).

They come into being as a natural part of human behavior.

For instance, we all place value on our time. If you ask me to do something, I will most likely ask for some form of reciprocation. Now maybe if I really like you, feeling good about helping you is payment enough itself, but there is a finite limit to that.

Even favors have an economic component to them. If you help a friend move, you reasonably expect him to help you move at some point in the future. Quid pro quo.

Our system of currency is a highly abstracted away formalization of those basic ideas.

Call providing some positive good or service "value".

You get reciprocated for providing value to others.

We use currency as a medium of exchange to represent this.

At times, it is easy to see this exchange. If you go watch a local band, you pay for a ticket, a portion of that ticket goes to the venue for providing you with a quality place to watch a performance, and part of the ticket price goes to the band for providing you with entertainment that you derived personal value from experiencing.

Other times, well, things are a bit more abstracted way. :) (And at some point it becomes arguable if value is provided at all, but that is a separate discussion!)

> It's easy to say people should not acquire worthless Film & TV degrees, when you yourself have a C.S. degree, only because computers have been your passion since the age of 8.

My argument is that people should acquire a degree that enabled them to provide value to society.

> I would not want to spend the majority of my precious time on earth with something I do not like to do. And of course I think other people shouldn't either.

The later half of the 20th century is the first time it was possible for a large number of people to have even a hope of doing work that they enjoyed.

That said, ask the people who laid your sewer pipes, built your building, pave your roads, how much they enjoy being out at 4am in the rain and snow working.

Ask those mining the rare earth minerals that are used to build our technology if they enjoy their jobs.

Middle class Americans have this romantic ideal of jobs being something someone enjoys. We are all spoiled and need to admit to that. But hey, it is a nice goal to make it so that everyone can enjoy their job right?

So here comes the funny part.

We are automating away the miserable drudge work jobs, and people are now worried.

Because it turns out the middle class fantasy of singing joys at work and coming home to a giant house with 2 (or 3 now days) cars and all that other assorted crud is not maintainable on a large scale.

I don't have a solution to this, really no one does. But we have to accept that we have made our bed and now we are going to lay down in it.
I'm guessing the only reason people don't spend a larger percentage of their income on rent is that most landlords require, as an absolute minimum, 3x rent as income per month.

Speaking of which, that rule will probably force me to get a job that I don't need just to rent an apartment as a student.
Tips:

* Don't have any scratches on your skin, or the salty water
will sting and distract you from the experience.

* Empty your bladder before you enter the tank, so you
don't feel the need to get out mid-way.

* Shower before entering and after exiting the tank.

* Some places can play your choice of music through the
sound system in the tank, so you might want to bring
some of your favorite music to experiment with,
if you like. If you prefer silence, you might
want to bring earplugs to minimize outside noises.

To be fair, the NeXT machines were not as fast as competing RISC boxes from Sun, HP, IBM and DEC, and were equally costly. Also, as you pointed out, it was not Unix-ish enough. It was the most Mac-like Unix machine at a time being Mac-like was not an advantage in the high-end computing market.

Memory is being counted in kilobytes. Processing time in cycles.

Curiosity, by this point, is extremely likely to be a required condition for intelligence in any species. You should look into the AI work done in developmental robotics and Artificial Curiosity...
My slickest move in LOTRO was to buy scroll cases -- which give random recipes -- on the auction house when they became available at the prices one could sell them to vendors at. Then I waited until an update introduced new recipes (most notably Coffee), opened cases, and sold some of the new recipes for scarcity value.

Before that, I built up a relative in-game fortune by buying low and selling high in all sorts of items, as well as picking my targets in crafting. My initial grubstake came from people who'd make items to practice crafting, then offer them on the auction house for the same price they could sell to vendors. I bought them, held on until no other copies were for sale, then sold them for prices that reflected their usefulness.

Really curious as if it's missing anything big.
Shame nobody has done a breakdown of exactly what is being held in this used up space.

From what I can find the system folder is 2 GB alone, but we're still well short of almost 5 GB of "stuff." We likely also have a backup image, and then just Samsung's bundled apps?

As a random aside: Why are they still selling 16 GB phones in 2013? I realise the chips are faster than what goes into SD Cards, but given the speed of SSDs and the relative price decrease year upon year, if phones were keeping up we'd be seeing at least 64 GB as standard!

What about solving this on the technology side?

We have fantastic technology in many aspects of life, but housing seems practically unchanged. I mean, buildings are constructed by teams of men placing pieces of wood by hand. Is that really the best we can do?

Dear VCs, you think a billion dollars is cool? How about a trillion dollars? Housing is that big.

For instance:

If Caterpillar, a hyper-conservative, risk-averse organization can fund this kind of stuff, surely VCs can.
You could two things to improve this. Allow cutomization of speed (the icons move too fast), and let one icon morph into another. This could become a visual cue for further navigation or a preview of the steps that follow a user sequence. On its own, a moving icon doesn't carry much value in a layout.

I am not smart enough to understand what this comment means, sorry.
Another reply, sorry about it, but that link has a great quatation from the BIS (so called Central Bank of the Central Banks, located in Switzerland):

Bank of International Settlements, which stated, "Foreign investors in U.S. dollar assets have seen big losses measured in dollars, and still bigger ones measured in their own currency. While unlikely, indeed highly improbable for public sector investors, a sudden rush for the exits cannot be ruled out completely."

The writing is on the wall for all the foreign US Treasuries holders. This and most expensive in 300 years of their history. Now, it's a chicken game. And the one who blinks first wins because looses the least of the Treasuries value.
The difference is that the Samsung Galaxy has expandable memory. So, unlike the Nexus 4 which comes with 8GB (total, usable is less), you just pop in a microSD and have plenty of room.
I bought my first Mac a TiBook when OSX was still in beta because I knew it was based on the OS that the world wide web was invented on. I've got the NeXT Bible at home on a shelf. I've been looking to buy a cube for years and have only found them for $5k+ on ebay. I know they're rare but does anyone have one they want to sell for a reasonable amount or know of a place selling them?
Improving LinkedIn’s UX (Part 1)
> And finally the idea of "contributing to society" is so nebulous I don't know where to begin. Is someone who makes a really good latte contributing to society? Is an investment banker contributing? Kim Kardashian? Zynga?

The way we have defined it in an open capitalistic market is that if someone is willing to pay you money, you are providing value!

(Societal value is obviously slightly different, since people will pay for things like hitmen, who are obviously providing value to one party but taking away a near infinite amount of value from another.)

And yes it is sort of a circular definition.

> Who said anything about corporations? Hiring people to do work has been a basic part of the human experience for thousands of years. Unless you can run your entire business on your own you're going to need help, and so you give someone else money to do what you can't.

So what we need is a certain % of people who are willing to be entrepreneurs, thereby keeping others employed.

Thus one has to ask:

• Are entrepreneurs being provided with enough incentive and possibilities to open their businesses?

• Has something changed from a societal perspective that has decreased the percentage of people who have an entrepreneurial mindset?

Obviously the first the government (and private industry) can help solve, but the second, well, that is a bit harder of a problem!
Covering how $a or $b does stuff on a PowerPoint slide
isn't the same thing as having students write a $thing.
Which sort of sucks when they go on the job and have to
write a $thing!

That statement is true for many different projects in many different niches. Colleges can't possibly teach them all. If they try, then classes spend less time on CS fundamentals and employers are unhappy. If kids learn about $thing, that means less time for theory and employers are unhappy. (Not to mention that practically speaking, less time on theory means they won't be passing "top tech" interviews at all.)

"We need people who know $thing" does not imply that "colleges should teach kids $thing" is true. Is $thing important because you know it and use it, or do you know it and use it because it's important?
They're all badly written bloatware like you'd expect.

Plus even if you remove them you still get the pleasure of storing a larger than necessary backup/recovery image with them inside just waiting to re-infect your phone if you ever factory reset it.

I own a Samsung Galaxy Note 1. While I think the hardware is top rate and I am happy with Android, I think Samsung's bloatware ruins the entire package. I prefer the experience on my Nexus 7 with "virgin" Android and my next phone will be a Nexus phone too for that reason.
I do wonder sometimes if standardized, truck haul-able modules of housing wouldn't be an interesting alternative to apartments. Build a building that you plug the modules. Want to move, haul the module to a new building.

Perhaps pulsars are interstellar beacons placed by advanced civilizations to signal a rendezvous point for any species capable of reaching it. (Anyone know if this is the basis for a sci-fi story?)

As an aside, I find it somewhat amusing when people lay out a statistical basis for how life is so incredibly rare to the point where it's unlikely that we even exist.
