ext3 without dir_index has a limit of 32K directories in any one directory.

Where I saw it crop up was 32K folders under /tmp on a cluster system. So no it's not a limit on number of directories entirely (that's inodes), but rather how many subdirectories you can have.

The success of dieting programs is that people change their habits from unhealthy behaviors to healthy behaviors. The most successful ones are done in groups that offer emotional support in addition to health education.

The point of these methodologies is to help replace unhealthy development behaviors with healthier ones and to use groups that offer reinforcement of the healthy behavior as part of the process.

Of course, much like diets, not everyone is really going to "buy in" to the new "healthy" habits. They will drag their heels, whine, and generally continue their unhealthy behavior.
JavaScript: String.replace()
Actually printf is a POSIX standard shell utility. Bash happens to implement it as a builtin, but there's also a conforming copy in GNU coreutils (and presumably busybox, but I didn't check). And the syntax above is standard Bourne shell, not specifically bash.

Actually of the constructs in that, the only non-portable one is the seq tool, which (I think) is unique to coreutils.
> when you go into a brick & mortar store to buy a digital object people get confused

For some part of the market I think this was actually a strength, though perhaps not a big enough strength, or not exploited well enough. We got my uncle (American, aged mid-80s) a Nook for Christmas 2012, in large part because we knew he could go to his local B&N to buy books and have them loaded onto it. That's worked pretty well: he basically buys books like he used to, except now they are more portable and he can zoom in to compensate for his poor eyesight, which is easier than reading paper books with a magnifying glass. With the Kindle we weren't sure whether he'd enjoy having to figure out how to shop online at Amazon. He rarely uses computers, and even more rarely uses the internet, so probably wouldn't buy books from a desktop connection. So he'd have to buy them online from within the Kindle itself with no local customer support available, which even to me seems like a confusing interface (it's not quite as bad as trying to navigate Google Play on a smartphone, but it's not great).
The real world and its constraints have this terrible tendency to intrude on the idyllic visions imagined around software development methodologies. Budget cuts, people quitting, timelines changing every week, internal politics, sabotage, personality issues - basically everything but the "methodology" itself.

The advice often comes (including in one of the XP books) that the answer to "bad projects/people/environments that you can't change" is to get a new job; this may work at the individual level (sometimes), but it does nothing to actually fix the broken projects, environments, or people themselves.

There is indeed no silver bullet. All these decades later, and many people still refuse to accept that.

What oinksoft said.

I think it's a common mistake of people who want to teach anything, but I see it frequently in coding (probably because that is what I am trying to learn these days). That problem is usually articulate with this phrase: "Before you get started..."

Essentially, when I look for a beginner's guide, I want to start at the beginning. There is nothing before the beginning. If I need to plug something in, turn something on, or install something, I'd like to know how to do that. I exaggerate only slightly. For example, when I was learning to play the piano as a child, I started centered on the first note I played, which was a G, and arranged myself accordingly to accommodate my chosen midpoint, since no one had taught me about Middle C.

Oinksoft's points are all crucial. You're clearly knowledgeable, but those details are beyond the scope of my understanding for a Level 0 beginner, so if they are essential, they need to be broken down. If they aren't, then you can leave them out.

As a general rule for teaching anything, you should explain, demonstrate, and then solicit a student response or reproduction of the concept. I think the material you have here can be arranged such that it accomplishes these components, and rearranging it thus would make it easier for someone ignorant of the subject, like myself, to follow along.

I hope this is helpful criticism. I really like what you're doing and I'm excited by your attitude – 'basics to ninja' – because this is useful for preventing learners from stagnating. With some work on the beginner level information, I think you'll have a solid guide.
> Startups generally have a bias towards doing things that they can measure accurately.

My fear is that many of them don't understand a thing or two about statistics, so all that precise measurements are means for them to lie to themselves.
I always wondered why B&N didn't spin the nook hardware division off and focus on providing the content.

Either way this sucks. I own a nook simple touch and love it. Hope they still keep their apps for other devices around.

I'm a frequent Redditor, and while I find the IAMA subreddits one of the most interesting ones, I'm pretty disappointed by how softball questions they were.

Reddit is a great opportunity to be more direct and poignant (always in an educated and intelligent manner).

For the people that don't know, the general "consensus" on reddit is that Bill Gates is awesome and Steve Jobs sucked, of course it's oversimplified but you see it around.

I for one would have liked to know if now with hindsight, he sees Microsoft's actions in the past over aggressive maybe hindering the progress of open source and stuff like that.

I can read in 150 thousand traditional interviews where does he see the future of technology and how exited he is about the cloud.

Monetizing a social user base is a great strategy for making millions of dollars. But Snapchat is clearly aiming at billions, or they wouldn't have turned down the multi-billion dollar offers they've already received. Facebook has little to fear from social apps with millions in revenue... so why were they willing to pay so much for a zero-revenue company? And why are VCs ponying up tens of millions in funding for a zero-revenue product? The potential revenue from these dinky little solutions suggested here won't even break even for the VC.

No, they have something much bigger and better up their sleeves. Leaving a few million on the table now in the interest of potential billions later is a very good trade.

Personally, I think the world is ready for a footprint-free social app - not just photos, but threaded conversation and what not. Like Facebook, only without anything for employers to troll and exes to stalk. I think they could literally beat Facebook. That's worth a lot of waiting and risk.

I hate to derail this topic to talk about 4chan, but I think that 4chan is many-faceted (and, indeed, the level of anonymity has varied across time and from board to board on the website) so I'm not certain an informed opinion could ever be COMPLETELY informed. Certainly, somebody lurking on /b/ for a few months might have something to say, but they're missing out on the sub-boards, which have their own board cultures and memes in microcosm. Again, moot goes to 4chan a lot, so I'm waiting to see what he has to say.

They talk about male babies who were sexually reassigned at birth and given female hormones. However many of them decided to reidentify as males later on life, showing that even with female hormones and a female upbringing, it was not enough to make them adopt a female gender identity.

I wouldn't say this is conclusive evidence. But I think it's enough to show that people should keep an open mind about this subject.

Those are clauses under "voluntarily performing any of the following acts with the intention of relinquishing United States nationality".

That specific clause says "the armed forces of a foreign state" - who is the foreign state here?

As a minor quibble, it's not "gain officership" but "entering, or serving in". Otherwise, enemy X could declare that you are an officer, with no ability on your part to decline.

Correct, I mixed it. The point is, it's interesting to know that gender distribution isn't entirely random and can change based on environmental pressure. That also happens with other species, although the mechanisms can be different (e.g., in crocs it's the temperature the eggs are exposed to that determines the sex). Given those gender distribution differences persist, there may be a survival strategy behind.
I agree that investing on these may seem more profitable in the short term. But branding is a long term goal. Even for Startups branding is important, this can be crucial to close the next deals with VCs or acquiring users' hearts.

Digital Ocean is a good example, I've read good and bad stories, mostly good and they had an extensive Youtube and Display Campaigns. When it was finally time for me to close a deal with a VPS to replace my old Dreamhost shared server I didn't have to search. I went straight to Digital Ocean.

This is harder to measure, or even impossible when you add the fact that I was probably impacted at least 50 times by passive or active advertisement for them on at least 4 different devices.

Also keep in mind that I was aware of this the whole time, and I smiled every tie I saw a DO ad, because I knew I was probably gonna sign at some point. But most of the time these type of advertisements happen without you even noticing, even if you are in this business.

Companies spend millions in SuperBowl ads, and nobody can click on that, it's impossible to tell how many coca-cola bottles will be sold by that ad and post discussions that it sparked. But they will do it again next year.

Display advertisement is valuable but it's harder to put a price tag. Even if you don't click on the ad in a mobile app it's still valuable. I'd argue that if you make it annoying or if you try to steal a click it's less valuable.

There is a reason this type of publicity is sold by impressions, because that's where the value is, clicks can or cannot happen, that's just a plus you won't get on TV.
Thank god none of you are in charge. Just kidding or am I?

Elop played the game straight forward. Forking is a half baked option and when you are leveraging your company, forking is not an option. You need full scale OS support and that means, Nokia could have either gone with MS or Google. Google apparently refused to make space for Nokia's competing service suite (Read-Business Week) and as such, the option was only MS. I know the hate is strong for MS in this community but it's way too illogical to think one man alone could have played his tactics and strategies to influence Nokia to switch to a MS OS for his career progression.

Meego was ruled out as an option as well. A tech-pretty thing may not always work out. WebOS taught us that lesson. So conspiracy theories are pretty meaningless.
I bought a Nook Color in early 2011 during a trip to the States (I live in Canada). It was the first Android device on which I did any sort of mobile dev or hacking. My first experiences with custom roms, in fact, was on my Nook Color.

Unfortunately, the Nook lineup couldn't compete with what was rapidly emerging onto the market. It didn't take long for my Nook Color to start collecting dust once the Nexus 7 (still my tablet of choice, even though I own larger ones) became available.

Year, those numbers make basically no sense. Even your link doesn't prove what it claims in the headline. The government shovels billions from the general fund into the highway fund every year. The highway fund disburses a much smaller number of billions into transit projects every year. Therefore the fuel tax does not cover the cost of highway spending.

starts to get complicated when you start questioning what "observed" means. Can we observe a gene? We didn't used to be able to, now we can. Was it faith before we could observe it?

Can we observe an electron? Or quantum particles?

What about studying distance stars, or investigating past events?

And where do empiricist get to the point of deciding that observing the world is something they can rely on?

I don't genuinely hold any of these sceptical world views (nobody really does, do they) - these are mostly hard to answer/explain questions I keep getting thrown at me when I end up talking to serious creationists.

You raise a good point. Wikipedia's policy of NPOV (neutral point-of-view) effectively means "mainstream"; while I grant that "controversy" on this subject exists in the mainstream, I believe in this case the mainstream is unhinged from reality. Thus, on this point, so is Wikipedia. [1]

Given the dramatically different reproductive incentives for women (one egg per month for ~25 years, 9 months of pregnancy plus lactation, etc.) and men (millions of sperm per week and potentially no more than a few minutes' commitment), biologically determined cognitive and behavioral differences are obviously the null hypothesis. In other words, the burden of proof is on those who claim that women and men don't exhibit cognitive dimorphism. Does this strike you as the "mainstream" view? For example, there are many who claim (or, much more often, merely imply) that women and men must on average be equally well-suited to engineering. Are such people routinely called out by NPR and the New York Times to produce evidence to support their position? Um, no. So, we can see that the mainstream is in error: even if it turns that there is such evidence, the mainstream doesn't generally demand it. (Indeed, those who do demand it risk censure for their beliefs.)

A survey of different cultures around the world tends to confirm the null hypothesis: a belief that women and men have different natures is a human universal. [2] For a rigorous account of the positive case that women and men differ in their cognitive and behavioral characteristics, I can recommend The Blank Slate by Steven Pinker. [3] If you're short on time, see his TED talk for a quick overview. [4]

Hey! You gave some great examples! Go to meetings. Talk to them. Send them emails asking about their work. Observe experimental design and data collection (if that's not public, that should be part of your judgement). Read non-publication sources (patents, regulatory submissions).

And then yes, do squishy stuff like "judge their character", "talk to their postdocs", "ask around about professional opinions". It's a conceit to operate as if science isn't a human endeavor.

Also you are now conflating the specific case of this project with the general case. Read their INDA, if you are really itching for details.

I'm not sure how you can use a flat statistic like $9,100/year to own based on 12,000 miles per year driven, and then apply it to a Lyft driver. They could be driving 45,000 miles per year, in which case the $9,100 per year would go up, but it's not clear by how much. I would guess that there are large efficiencies there. There are another number of flaws with this logic:

1) Assumes that you only use your car for Uber/Lyft driving and that it is entirely valueless otherwise. If you were going to own a car anyway, you were going to eat a bunch of that cost to begin with. The extra costs are in the incremental mileage that you drive.

2) Assumes you are buying a brand new car, and uses averages for first 5 years. If you just start with a 1-year old car, that drops your average around 25% (from ~$9K to ~$7K).

3) Averages across a number of makes and models, including a number of luxury cars (pretty sure most people looking to earn $35/hour aren't in the market for Porches, Land Rovers and Mercedes Benz', all of which top out the scale being used in the consumer reports article). For example, a Toyota Camry would cost about $5,700/year to own for years 2-5 (http://autos.yahoo.com/toyota/camry/2013/l/cost.html), and around $7K/year for all first 5 years.

4) As stated earlier, assumes that a Lyft driver is just going 12,000 miles/year and that the rate $0.75/hour stays constant regardless of how many hours you drive in a year.

5) As far as I can tell, you can write off your expenses on your taxes, recouping part of the value as well (standard cost at 56 1/3 miles per gallon: http://www.irs.gov/publications/p463/ch04.html#en_US_2013_pu...).

Not quite sure how to evaluate, and it's very possible that I may have estimated on the lower end. But, the methodology used in that blog post linked is pretty visibly flawed in a number of ways. Now I've already given this more thought than I initially planned to, but you're right that I shouldn't have off-handedly thrown out $5/hour without investigation. That said, it bothers me that the blogger you referenced put out an entire article (that was referenced on HN) that used such poor reasoning and assumptions using misleading data. All of which to come up with a bolded "$3.45/hour!!!" conclusion. /rant
