I find of the most exciting tidbits about scalability from reading the mailing lists of popular data stores that people are ramping up to huge deployments (MongoDB and Cassandra primarily, but Redis and CouchDB occasionally).

All those people with multi-TB systems scaled across many data centers inevitably end up on those lists asking great questions about exactly the types of problems you run into at that level.

It helps give you perspective before you are the one with a geographically disperse collection of terabytes of data; which can be a godsend.

Kudos for turning a defensive move into PR gold.

Absolutely right about Australian-Indian racism debate. A lot of Indians doing very well here, and the last time something flared up, the news attracted a lot of unwanted attention to the nationals who have settled down here.

I'm sorry to have distracted people from a meaningful discussion. You have executed well, and this has to be discussed.

"Is the driver really the highest marginal cost in the system? Does removing a driver really drive costs down that much?"

Absolutely. In Austin, we have car2go, a car sharing program that allows one-way trips. Gas, insurance, maintenance, parking, and any other cost you could think of is included in the price. It costs about six dollars for me to drive downtown from my apartment. A taxi costs $15.

This isn't a perfect comparison since I walk to a car2go, but a self-driving car might need to drive to pick you up. It's pretty close, though.

Cars didn't invent the road, certainly not the city-based road, anyway.

Most of the worlds largest cities were designed and laid out long before a car was ever even dreamed of.

Roads, laneways and streets are a feature of every single ancient civilization. Mass transit is good at being mass transit, but personalised transportation (whether foot, bicycle, animal or vehicle) is always going to be with us.

Of course the future is cars for the majority of people, because the majority want personalised transport where mass transit is incapable of bridging the gap.
I must be missing your point... please explain.

"I can’t distribute my program without also distributing its sources if it contains a copyleft component."

Well that's perfectly fair if that's what the original author wants.
If you want to distribute derived work from my copyrighted material, I've decided let you do that without paying me or even talking to me as long as you follow some rules (maybe the GPL, whatever). You are of course free to contact me and negotiate a different deal. You are, after all, wanting to use MY copyrighted code to build something and distribute it.

"Copyleft also contains all the asymmetry of copyright: licensees will have their right to silence violated but the original creator can go ahead and create proprietary derivatives."

If I write code, of course I'm free to distribute it however I want. I can grant various permissions to people normally not available to them due to copyright law.
"Licensees" don't have any rights violated - they have whatever rights they chose to accept or negotiate or purchase or whatever when they decided to use my code and what that would imply. In the absencse of that license, they simply can't use my code at all. They are free to write their own.
They are also free to contact me and negotiate terms.

I think I'm missing your point though - what is it exactly?

I spend basically all my free time reading, engaging in self-improvement activities, and plotting for my eventual world domination (heh).

I'm 46. I spent my twenties doing therapy and reading endless self-help books and so on. It was the right thing for me but I eventually got what I needed from it, ditched all the self help books and began living more. A few thoughts:

It doesn't matter that much what most people around you are doing. It matters much more whether or not you have a handful of people close to you who are on the same page with you. There is only so much time in the day and it takes quite a lot of time to establish and maintain a close relationship. See if you can find somewhere between two and six people whom you get on really well with and quit worrying about what most folks are up to.

Reading self-help books and doing therapy had its place for me but looking back I consider it the slow-mode part of my life. It was something I did when I was too weak/fragile for stronger stuff. If you are up to it, find a mentor, do some traveling, hurl yourself into something new. Bite off more than you can chew and all that.

Your remarks in this thread read like someone who is very bright and hasn't yet figured out how to adequately meet their intellectual needs. This seems to leave bright people with a chronic gnawing hunger for "something more". Reading is a good thing but not necessarily the biggest mental challenge. If you can find some means to get adequate mental challenge/feed your mind what it hungers for, some of these other dissatisfactions may seem to magically disappear (or mitigate).

Some of your complaints (about the weather, vitamin D, etc) imply you aren't getting what you need physically. Work on that. If your physical health is sub-par, it really takes it toll. "A sound mind in a sound body" and all that.

Anyway, I enjoyed your remarks. It's the main reason I am replying. Best of luck with putting your plan together and finding what you need.

This is typical for almost anything, from 3d-TVs, to cars, to cheap airline flights. Unless something is universally loves or hated, it falls into this category.

The difference is in the amount of overhead and abstraction and consequently the amount of work a programmer needs to do to access the data securely. The underlying layer is obviously the same physical medium in either case.
Automated taxis will be cheaper and more convenient than owning a personal vehicle. The taxi driver is a significant cost.

If you're sharing a car, you're paying a smaller share of the capital costs. Most people don't do that today because it's inconvenient. If cars drove themselves, it'd be convenient.
In North Dakota, weather is not a perceived problem. Cars work everywhere, and it is likely that he replacement needs to do the same.
I find myself wanting to like WP7 (the Lumia specifically) but that may just be because I respect the different approach they're taking.

I can't imagine a circumstance where I'd ever buy another Android phone (the 2 I owned were miserable enough experiences to put me off the platform for good), and that was before I ever used an iPhone. Now that I've invested in the platform (apps, media, and hardware peripherals) it would take a revolutionary breakthrough to switch.

But deep down I like technology, so I hope to see that breakthrough.

I have a lot of non-IT stuff that I'd like to know at one time - so, in a spirit of sharing our TOKNOW lists, my current one:

- Economics
- Micro
- Macro
- "Applied" - stock markets, credits, all that stuff - how it works, etc. (I know almost nothing about it)
- Knowledge about societies - how they form, how they function, etc.
- Bayesian probability (working on it right now, thanks to AI Class), set theory, maybe category theory
- Control theory (I do really, really regret I didn't care about this at university)
- Biology
- Genetics 101 & blood groups (I forgot all this stuff since high school)
- Nutrition 101
- First aid
- Pretty much whole physics (Feynman's lectures sitting on my bookshelf and waiting ;))
- History
- of civilization, especially Roman history
- of science, technology and enterpreneurship
- of modern geopolitical structures
- Geography
- World energy infrastructure
- How many resources do we have, where they are, how fast we use them
- How the world trade works
- Literature
- "Homeless People"
- "Crime and Punishment"
- ... and then some other good books

And that's really just (non-IT) knowledge; there are also some skills I'd like to acquire that are not listed. I know some (most?) of that stuff was covered in high school, however I somehow missed it all then (I didn't care / school wasn't really helpful to make me care). This list reflects some topics I spend time thinking about / worrying about, but at some point I realized I should either sit down and learn some of it, or stop caring that much about things I don't understand.

From the technical side (which is actually the main topic ;)), I keep all of this in plain text; it used to be .txt files somewhere on my hard drive, now it's in Org Mode.
A 3 mile cab fare in Berkeley is $20+. The all-in cost of driving a basic private car is around 55 cents a mile (or 90 cents for a BMW). That only leaves license cost, so unless you need a $500,000 medallion, the rest goes to the driver. (And as long as the driver works for himself, the medallion is a capital investment which he can sell later.)
Her other blog posts are perfectly credible, and she comes across as a somewhat harsh, and typically cynical sysadmin...

...from which most of the things you've quoted follow pretty naturally, whether the author is male or female.

You're right, you don't need to mention sexism to make any judgements. So why should we assume that sexism is to blame when people dislike her? I've disliked most sysadmins that I've interacted with, regardless of sex, and that includes myself, when I've been forced into that role...it's a shitty job, and while somebody's got to do it, we never like the "assholes" that end up complaining to us about how our dev practices affect ops people. But the rest of us don't try to pin that on X-ism, we just accept that it's an unpopular position within any company...

Once you switch over to autonomous taxis, so many possibilities open up:

Imagine eliminating most visible parking. A small fraction of the world's vehicle fleet is in use at any given time; the rest of the time it's taking up a parking spot. Remove that and we can have wide sidewalks and bike lanes, parks and new development. Suburbanites get an extra room in their house and a bigger yard.

Buses and light rail become obsolete, but heavy rail transit becomes much more practical, because the door-to-door problem is solved. A virtuous cycle of improved convenience, leading to greater ridership, leading to more trains and shorter headways could result. It makes a lot more sense to ring the bay with a 150 mph train when getting to and from the train is easy. (Then again, it might be easier just to run the taxis at 150 mph on dedicated roads.)

Very well executed response. If they can execute that well on this I can imagine that they are even better on product development and customer service.

I don't understand the comments against their response. I find shameful that a paid blogger tweet against a competitor with a subjective attack without disclosing the conflict of interest and that the guy paying the blogger chimes in insulting the competitor.

"""First, Apple is suing over the Xoom's design, not a technical patent"""

Gee, maybe that's why I fn wrote "Xoom was also bloody similar", and added the technical patent issue on a separate* line where I'm NOT talking about Xoom.

"""It was obvious to me which was the iPad and which was the Xoom in every comparison shot. """

You really believe that the litmus test of an original not derived design is that you are able to tell which is which?

There are tons of Rolex clones that you can easily tell from the original, but that doesn't mean the haven't copied it.

And it sounds to me like you're one of the people who actually defend companies not even trying to come up with something different.

I have a syslog-ng -> MongoDB project that I've been working on at my university.

github.com/ngokevin/netshed

It is written in Python current parses out fields from several types of logs (such as dhcpd). It is initially set up to read from named pipes (it has a tail function as well). Each type of log is dumped to its own database, and each date has its own collection. I have it set up with a master/slave configuration to overcome the global write lock. It has functions to simulate capped collections by days. It is followed with a Django frontend for querying via PyMongo.

This version is several weeks old and I will push out a new one soon.

"How do you piss off a technical woman so she will leave your team? It's easy. Just go and lob a few complaints about her behavior that would never apply to a guy. The easiest one of these is to say "you're being too emotional"

If that is the entire point of your blog post, then you'd best make damn sure that you're not "being too emotional" in your accusations therein.

A lot of people, myself included, think that she was being too emotional, and hence unreasonable, in her accusation of sexism in this post, without ample justification. The fact that she paid lip service to the criticism beforehand and tried to chalk it up to sexism does not absolve her from it.

Similarly, even if I say "Some people will call me racist, but they're just minority-lovers..." before I launch into a tirade about how much black people annoy me, I'm still spouting bullshit. The fact that the present author is taking an oppressed viewpoint rather than a majority one does not change the burden of proof.
As CEO of another Indian startup, I am furious that anybody would drag nationality into this. There are no boundaries on Internet, and certainly Girish rightly says that commenting on nationality simply reflects poorly on his own maturity level.

Aren't most of the products rip-off in some sense? Take Apple, Google, Yahoo or any other company out there. Rarely, if ever, a company comes up with something totally new and innovative that it doesn't resemble anything else in the market. A new category, that is. ZenDesk didn't invent helpdesk system. Instead, like all other companies, they are evolving and perfecting helpdesk systems. FreshDesk is also an attempt at this, (and so is our product Visual Website Optimizer for A/B testing tools).

I wish companies compete in a professional and respectful way, this war of words simply disgusts me.
> Well that's perfectly fair if that's what the original author wants. [. . .] You are, after all, wanting to use MY copyrighted code to build something and distribute it.

The form of your commentary here seems to assume that appamatto agrees that copyright represents an actual "right". I do not think that assumption is reasonable in this case.

> "Licensees" don't have any rights violated - they have whatever rights they chose to accept or negotiate or purchase or whatever when they decided to use my code and what that would imply. In the absencse of that license, they simply can't use my code at all.

Are you suggesting that there is a basic human right embodied in copyright law, or are you just labeling legal powers and privileges with the term "rights"?

> I think I'm missing your point though - what is it exactly?

If you do not assume that everyone in the world shares your own beliefs about the appropriateness of copyright law, I think you will take a huge step toward understanding appamatto's essay a bit better.
This is less about scaling and more about any random technical knowledge you might need:

1) Companies with Serious Scalability Needs have a lot of organic knowledge in them, which you gain both a) by being mentored by senior team members and b) by baptism-by-fire.

2) Companies with Serious Scalability Needs have training budgets larger than YC's total amount invested to date. (Just a convenient ballpark figure for "Holy cow, that's real money!") They spend it to e.g. send engineers to conferences where people with organic knowledge of the subject will teach you best practices (i.e. Here's how we got burned, here's what resulted in less burnination). For example, ex-day-job dropped ~$20k to send myself and one other engineer to JavaOne, where we heard e.g. the chief architect from LinkedIn talk about what sort of caching strategy you need to have writes appear instantly consistent to the user who initiated them while achieving eventual consistence over many thousands of other users who they would fan-out to.

3) Largely as a result of the conferences in #2, there are presentations and, more rarely, videos online produced by people who do this sort of thing for a living. You found HighScalability.com , so that is good. I have learned a tremendous amount of not-covered-in-college-or-personal-experience technical data by consuming SlideShare presentations and following the output of people who routinely produce good stuff on particular topics. (For example, not exactly scaling, but the YSlow team created huge amounts of value for me by presenting on the how and why of web-page performance optimization several times.)

4) People who know this stuff are available to teach it to you, if you have tens of thousands of dollars to spend on it. If you don't have tens of thousands of dollars to spend, you probably don't really have scalability problems.

5) Most startups have the scaling problem "We have no scaling problems!" For the rest, there's a lot of "Smart people plus challenges plus lots of headaches = we pushed our personal skill levels a step forward."
