iPhone Development: On the fate of SQLitePersistentObjects…
Yep! Sorry, I was too lazy to write out "world wide web." And technically, with UseNET included the web is closer to 30 than to 20.
WP Design Blog
This blog is about Word Press themes ,word press design blog, wp themes, web design, templates & plugins, all that focus on blogging.
For new years we kept our keg on the patio to keep it cool. But that's just because it wouldn't fit in the freezer :P
Here's what works for me:

Keep a SIMPLE running list of tasks in a plain 'ol text file and sort them by priority. If you find yourself "spacing out", grep the list for the easiest thing you could possibly do and do it immediately. This often get your engine running.

Assign specific times for surfing and goofing off. Give yourself one hour in the morning to check email/news/blogs/etc... and don't surf again until lunch. Another hour or so, max, and then back to work. It's amazing what you can accomplish when you aren't reading about other people's great accomplishments.

Reconsider blogging. Yes, I know, this is heresy. However, I found that it was really hurting my productivity, and my desire to create a great blog post was sucking time away from creating a great app.

Challenge yourself. If you are feeling frustrated, pick the thing you've been avoiding like the plague and attack it. Tell yourself that you aren't stopping until it's dead or at least extremely subdued. You'll feel so good at the end that everything else will seem easy.
Kaspersky Lab Launches Malware News Site Threatpost
I try not to take needless potshots: in this case I think the two names I picked fit my argument perfectly. These aren't people who are famous thanks to credentials or expertise: they're famous because it's easy to be famous online regardless of aptitude or skill.

Julia Allison is pretty harmless - she's a socialite, and part of being a socialite has always been fame-seeking - but Doctorow is a lot more insidious. Here's a guy who has no credentials other than that he started a big blog, and somehow he's become an authority on art and writing and copyright. I think that a part of his popularity is that he's championing something people like to like - end copyright and all that - and so even though his writings are fairly clueless, people read them because they're simple and agreeable. But it pisses me off when I see him in newspapers writing about things like the future of art, because there are a lot of really bright people (Clay Shirky?) writing about this who actually know somewhat what they're talking about, and they're all better writers than Doctorow is too, but they're less read because they have less public attention.

Sometimes I think there ought to be a movement online attempting to highlight those bright people who don't seek attention. I don't know how it would work objectively, but I still feel that some very bright people get overlooked.
I'd actually prefer the gray water be used to heat the floor in the bathroom. If you've ever stepped out of a shower onto a tile floor you know how cold it can be sometimes. And if you've ever stepped onto a (electrically) heated floor, you'll know how awesome it is.

Running the warm water through a series of pipes below the bathroom floor would seem like a pretty good use of it to me, when compared to just dumping it into the sewer as-is.

Then of course, in a green house, the gray water would be collected and used to flush the toilets.
The Crowd hates anyone who might rise above, starting with MBAs, and it's easier to blame them than the horde of dumb customers who happily buy inferior products at inflated prices.
Asking out of ignorance: If you move your large textfields out of the database and into a file how will that improve your performance? Yes the DB will be smaller and thus faster, but won't it take proportionally longer to load your text from a file somewhere thus nulling your DB speedup?

No, he means that by putting this on the main sewer, you are running your cold drainwater through the same exchanger. If you put one under the shower only, you know you're starting with hot water.

Really, if you were starting fresh, you'd probably want a hot drain and a cold drain down in the basement.
The Importance of Playdar
If this is true, its a real pity. Music industry is really though business to go online. It's essentially trying to tie two very different business models together. ITunes got the magic right, but even that took a bit of wrangling.
I started working on my startup immediately after graduation 1500 miles from my parents' basement. I found a cheap room in a boarding house from which I work and tutoring rich private school kids just four hours a week keeps me going. For a little padding, I took a tiny loan from various parts of the family - it really annoys me when people assume anyone can find a $20,000+ loan from "friends and family," (I can't) but my family is almost exclusively low-income and was able to put together a little something that helped cover incorporation, business cards, etc.
"first of all, what's hard for one person can be easy for the next. "

no doubt but the question was explicitly what part of the coursework was hard, not the actual practice of business, which we all acknowledge is very hard.

"Also, whether a person finds something "hard" or not doesn't directly relate to its value. I wouldn't find it "hard" to spend hours reading case studies, but they are tremendously valuable since you can learn from other companies' successes and failures and apply them to your own company."

I didn't claim any of that. The question was solely about a statement in the original post and asking for examples in order to understand the point made, because in my experience MBA coursework is an order of magnitude easier than a masters in say Physics. My experience is not necessarily universal of course.

I don't believe an MBA is useless, but I am not so sure what quantum of value it does have. Hence the question.

"Did you come just for this topic?"

To comment in just this thread? No, I will probably make other posts. I lurk, and have been doing so for at least a year--so I wouldn't hold my breath if I were you. I just felt like sharing my ideas and (limited) knowledge as they relate to this topic, that is all.

"In this utopia you describe"

Utopia, as in, the part where I describe the use of desalinized water to irrigate crops, or pumps to keep sea level rise at bay? Seems pretty feasible.

"If you're wrong on that point, then we've hurt people for nothing, right?"

Are you implying that every dollar that goes to renewable energy R&D would instead go towards 'alleviating hurt'? Could I instead claim that every dollar for renewable energy R&D will come from our defense budget, leaving our 'alleviating hurt' budgets untouched? Now, are either of those reasonable assumptions?

"Since we're cutting and pasting from web sites"

I didn't cut and paste from any web site. I synthesized my own ideas. Well, except for the first two paragraphs, which came from the available literature/news sources I have ingested over the years. So, if you've read the content from the first two paragraphs on other websites, did the information concern you? Did it prompt you to do your own investigation into the available literature?

"Everything else is just philosophy."

Everything besides what the website you included says? Or parts/all of my comment? You've confused me with this statement.
"The core of the answer lies in something called the Capital Asset Pricing Model and it is as every bit as complex as the fixed point combinator for which YC was named."

Well I don't think the y combinator is a particularly complex concept and I did accept finance as hard and explicitly asked for non finance examples, :-) but that said I see your point (upvoted!).

"doing real market research for a natural foods store to determine if they should expand their footprint to other locations or just increase the size of their current store. It took over a month to design the questionnaire before the prof deemed it acceptable."

If I understand this correctly, the coursework is hard to the degree it intersects running a real business (in this case, as you said, doing " real market research for a natural foods store".

"With that said, the real challenge, and what any top school does, is teach students how to prioritize."

yes, but this is hardly unique to an MBA :-)

I've heard this over and over, but in my area many people have been switching from gas to electric and saving money. Now that gas prices are supposedly starting to fall because of lack of demand maybe things will start getting rational again - even with lower distribution costs there should be no way electricity would be equivalent to gas, much less cheaper.

"Reconsider blogging. Yes, I know, this is heresy. However, I found that it was really hurting my productivity, and my desire to create a great blog post was sucking time away from creating a great app."

Using your own advice,("Assign specific times for surfing and goofing off. Give yourself one hour in the morning to check email/news/blogs/etc... and don't surf again until lunch. Another hour or so, max, and then back to work.") one could just allot a couple of hours a week to blogging and thus avoid it becoming a productivity sink ;-)
The Perfect Server - CentOS 5.2 [ISPConfig 3]
About time. We had quite a few discussions with the registrar in my university about the benefit of converting a numeric grade to a letter grade (round to the neared quarter), which would then be converted back to numeric to compute the GPA.

I don’t think anyone reasonable can argue the merits of integrating computers and technology into school curriculums, however this plan by the schools inspection authority in England has the potential for parents to incorrectly point the finger at technology as the main reason why kids won’t be taught traditional subjects:

“One curriculum theme - "human, social and environmental understanding" - combines history, geography and religious education. Schools can decide which two periods of British history children study, allowing them to drop traditional features such as the Victorians and the Second World War.”

The proposal to lump subjects into themes, giving schools leeway to choose what subjects or topics within those subjects to drop, has nothing to do with the integration of technology into the curriculum. The backlash will undoubtedly link the two and say that children in schools are not learning WWII history in favour of learning how to blog or use Twitter.
The SAT is a little over 2 digits, too. First, you can never get a 755 or something - it always ends in a 0. Then, you can't get less than 400 and more than 1600. So it's 1-120, again.

Agreed. You just have to set priorities and know yourself. My "goof-off" time is mostly used for research on various topics and that takes priority over blogging for me.

Environmental science is inherently stochastic and messy, but to write off an entire branch, as you seem to have done, is unfair to those who pursue careers in improving our understanding of climate.

"there's no way to confirm that the people behind them are actual "climate scientists", whatever that means"

Well, the system that we have is that of peer reviewed literature. People who are interested in environmental science or other related fields pursue research in those fields, and some happen to research climate.

Why do you put the words 'climate scientists' in quotations? Yes, there are scientists who study climate, much like there are scientists who study other environmental/biological/chemical phenomena.

"It's hard to see who's who anymore, but smug confidence like this definitely rings my alarm bells."

I'm not sure what this adds to the discussion. Could you perhaps rephrase or reword; maybe I've missed the content of the statement you intended to convey?
I'm just launching own startup this spring, so I cant say for sure...

But if I succeed, I'll probably keep doing what I do now - code, blog and do startup once again.
Unless you're refrigerating your water, the water going down the drain will always be warmer or at the same temperature as the incoming supply. Since these things don't hold water, they exchange the heat as the incoming and outgoing streams move past each other, thus the effect is essentially null when you're using cold water (brushing teeth) and positive when you're using hot water (shower). When you're using water "asynchronously" (bath, toilet), there's no effect since the incoming and outgoing water move at different times.

You're reading me correctly. My claims are basically that:

A) I think that very few people actually believe that global warming could only be caused by anthropogenic forces.

B) I've never actually heard anyone claim that global warming could only be caused by anthropogenic forces, so if people are even saying that then they are in a small minority.

(The difference between A and B is that there may be people who say global warming can only be anthropogenic for political reasons even if they don't believe it. However, I'm saying that even the people who say this are a very small minority.)

Now clearly your quote supports your claim that Mann is saying this, at least in the abstract. However, my guess is that he's saying this more for political reasons than scientific ones. Which IMHO is reasonable, considering that implementing a legally binding cap on carbon emissions is the best course of action considering what we know today.
Being a VC/Angel seems pretty fun, but knowing myself, I'll probably get itchy and want to jump back into the game at the first opportunity I see.

Apparently starting a startup for startups is becoming a more and more popular post-sale activity.
I've seen a lot of cognitive enhancement articles lately that only focus on CNS stimulants and similar drugs like modafinl. I'd love to see more coverage of non-stim nootropics like alcar, racetams, sulbutiamine, deprenyl, etc. I like the dopaminergic stims too, but I don't feel like they are a good long term or healthy solution to cognitive supplementation.
I do not know. You may be right. That's metaphysics. In practise you can't even tell whether the universe is like a movie or a computer game.

I.e. a movie on a film reel consists of frames that are created once and when you watch it looks like a coherent story --- but when you paint over some frames at the beginning, it has no effect on any other frame.

Whereas when you manipulate the state in a computer game --- say, give Super Mario that mushroom --- you change everything that comes later.

And for that straw man theory of causality: You can just exchange it for a theory that postulates a cause for everything _but_ the Big Bang.

(By the way, I do not believe in causality. At least not the kind of mono-causality exhibited in human storystelling, esp. stock market commentators on TV. Strangely I still manage to believe in determinism.)

I haven't sold my start-up, nor has it publicly launched, nor do I want to sell it if the opportunity arises, but I'd imagine you go on to your next big idea.

The people who do startups like the freedom of working on their own thing. That doesn't extend to just startups. Design video games, or direct a movie, or start a band.
I thought one of their main points in the paper is that there are always going to be more data sets in "natural" form than in conveniently marked-up form, so that a researcher has to develop tools to deal with natural data as they are and still cope with that. Then the next new-and-improved scheme for semantic mark-up can learn from what is observed in vast data sets.
Often, go to work for the company that acquired your startup for a period of several months to several years. Few deals are structured so that the founders can just walk away after selling.
Beyond that, the most common path it to start another startup. It's addictive!
>>> Take marketing, for example. It is often misinterpreted as purely "promotion" when really it also encompasses product development, pricing and placement.

I up-vote on this alone! I actually have an essay about this that I plan on posting one day. Marketing is one of the most misunderstood aspects of business from those not involved in it. I'd guess that 9 out of 10 people think marketing is advertising and promotion.

In reality, as you said, developing a product is marketing. Understanding markets, segments, what the segments value and how to create a competitive product within those boundaries is extremely difficult and really is The the core of what a business is. The marketing strategy lies well beyond promotions and really encompasses the life of the business.

Yeah, after giving it some thought, it would be very tough to repurpose a realtime physics simulator like PhysX or ODE to be useful to Anybots. But that doesn't necessarily mean that it isn't practical to create a simulator suited for rapid prototyping of robots.

(I'm just brainstorming ideas in the rest of this post; I'm not sure whether they'll work, but it's a fun problem to think about.)

Perhaps it would be useful to write your own simulator that incorporates data about how the components of the robot behave in the real world, to get a more accurate simulation. By that I mean, the problem is that the robot model has so much complexity that it's difficult to simulate accurately. So instead of creating a mathematical model for how a compressed-air actuator behaves, for example, gather real-world data about how it actually behaves in the robot, then incorporate that data into the simulator. I mean, if the robot is walking slowly on a flat surface, then its individual components behave in the same ways each time the robot takes a step forward, right? Therefore it seems like the behavior of the whole robot can be reproduced and predicted in a simulator, since the behavior of each component is known (under controlled conditions, like when the robot is walking slowly). Brute force the problem by using large amounts of real-world data, is what I'm getting at.

Amiga, Inc./Hyperion VOF has already released Amiga OS 4.0, and it's sequel Amiga OS 4.1. It runs on the Sam 440ep, as well as the classic Amiga, and AmigaOne computers (and Pegasus now as well if I recall correctly). The OS has been rewritten from the original version to support the PPC platform, but it appears to need a separate release for each individual platform (driver reasons maybe? I don't know.). As of now, it doesn't support any modern high-speed CPUs and the newest graphics card it seems to support is the Radeon 9200. It is not a secure machine; memory protection is merely an option which individual programs can decide to opt-in only if they want to.

I'll probably waste some time contributing to open source projects and then invest into hookers :)

Article mentions dot matrix printers.. I've thought a few times that if there was an easy way to get a daisy wheel printer I would. There are situations where it would be neat to be able to set one up as a permanent record and as a fax substitute. I have multiple homes, and it would be an easy way to send a message to non-technical people living in the houses that I have servers sitting in where I might be in another country for years at a time.

In this book (http://en.wikipedia.org/wiki/The_Cuckoo%27s_Egg_(book)), Stoll talks about hooking up unix terminals to daisy wheel printers so he can review input later on.
