This is a tough one, probably deserves an article by itself!

We have a team of volunteer moderators that I find incredibly valuable. These are users that love our product so much that they are willing to spend a lot of their time helping us without any sort of compensation - and I cannot thank them enough for that.

Other than moderation, we also have to deal with all sorts of spammers and scamers. We were so naive at first, we built a system expecting everybody to be honest and good - well, that turned out to be a mistake.

Fast forward a few years and now we have generated enough IP on automated countermeasures against spam/scams and automated moderation that we could probably spin off a business to monetize that.

Anonymity definitely brings out the worst of some people, it is rather shocking.
Presenting a unique CMS w/chat, bots, link aggregator, rss, and more
Features:<p>* OOP/MySQL/PHP/HTML/CSS/JS/Jquery/scrollTo+LocalScroll
* Documents organized in tree hierarchy, each document can act as directory
* Every edit of a document saves a new revision with the old document
* Chat integrated (chat notifies of cms events, uses long polling)
* Aspect oriented (aspects can be toggled with commands or in sets- a user's aspect can be refreshed from the server by setting an aspect_preference variable to 2 (0 means off, 1 means on, 2 means needs refresh)
* Command line (defaults to chat input, commands begin with forward slash)
* Bots (Bot commands can be added as easily as adding a document in the appropriate place, bots can execute code. Bots respond to users they are focused on, when active.)
* User-selectable stylesheets + individual css rules (styles are editable within the CMS, individual style rules are applied after loading style, added with /set body background black)
* Easy to add new commands (/addcom) (commands are stored in CMS as javascript and loaded at runtime)
* All aspects and commands are listed with /help
* Aspects are remembered between sessions (ie: looks the way you left it)
* All aspects, documents, commands, and users have access levels
* Uses Ace editor for editing documents
* DB info stored in database/config.php - run the .sql then login with admin/admin
* Integrated link aggregator with full cache (fetches link with wget)
* Integrated RSS feed parser using lastRss.php (in progress)
* One aspect is called the 'metabrowser' which is an iframe that loads a URL on command (usage: /bload http://reddit.com or /meta) .. the url is also remembered between sessions.
* There is an interesting JS function called 'simcom' which simulates a user typing into the command line- works for both commands and chat messages. Usage: asgConfig.simcom('chat message or command!')<p>Get the source [here](http://github.com/ambiversive/asg/).<p>If you want to see a demo go [here](http://improvise.it/core), although it is not secure enough to let me let you edit docs with it.
The most interesting takeaway here is their clever use of a meme to engage in SEO for runningshoes.com.

However the discussion itself (and not the technique used to start it) probably doesn't add much to HN so I'd consider this spam.
Steve Jobs and Dennis Ritchie were obviously major pioneers (and I admired them both), but of the three, McCarthy's work impresses me the most. I still marvel at the profound degree of lateral thinking evident in his articles.

I suspect this will be the least well reported obituary, which is kind of sad. He was surely one of the greats.
Why in G-d's name are you people hemorraging about who or where the source came from? As great a man as he was, this doesn't warrant coniption fits about who knew what first. You're acting like he held national secrets that upon his death would lead to some catastrophe. Give it a rest. The man was in his 80s and led a wonderfully productive life. Get back to work, assholes.
Thanks. It looks like a 4500W fixed tilt system in Seattle would generate 150 to 572 kWh, depending on the month. 4364 kWh per year, which is not too bad. 1 axis tracking brings it to 5492kWh, 2 axis tracking to 5819kWh.

http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/US/...

It might become reasonable in Seattle at some point, depending on the costs of installing a system with tracking. One should also factor in that peak output decreases over the life of the panels in figuring out lifetime cost/benefit, and not just look at output numbers from the first year.

It's important to establish what specific area we are talking about in these discussions and what particular sorts of systems we mean and their actual complete costs. Not everyone lives in Florida or Hawaii and my understanding is that tracking systems are quite rare and have their own issues. I've only seen one tracking system myself, it was at a school installation that was done in a field. I have not yet seen them on rooftop installs. There is little information about them but often estimates include numbers assuming tracking.
Is this true? Has Amazon/AWS asked people to take down blogs/articles that benchmark their systems?
The web existed prior to Facebook. You seem to be arguing that Facebook's very existence is the reason that other sites on the web can even exist, which seems to fly in the face of the history of the web.

Optimal tilt just refers to the tilt the panels are installed at, no tracking.

His method might increase clicks in the aggregate, but I wonder what the backlash is against other people.

Personally, every time I read one of the "You should follow me on Twitter here" callouts, my response is very close to "Go to hell, don't presume to tell me what to do." While of course I can't remember everyone who's used that stupid canard at this point, ceteris paribus it's a behavior that I think would greatly decrease my interest in working with or buying something from 'em. 'Cause its douchey.
Crevasses are normally encountered during glacier travel. These aren't particularly common on steep slopes.

Moreover, climbing as a trio tends to be (much) slower than traveling as a pair. When weather and hypoxia are your biggest threat, speed can literally be the only thing keeping you alive.

Or just track the (presumably few) mutations of permspace objects for special handling. In that case, permspace effectively becomes an infinitely long-lived generation that is never collected, only used as a source of roots.
If this were true ("solved"), it would be the prime argument for a centrally planned economy. 'Free market' isn't a solution, but a heuristic that produces a non-horrible moral outcome.

One of the reasons we discuss things symbolically is to hopefully take advantage of the structure of the problem to generate a better outcome. Your reduction of journal-access to free-market is about as useful as a reduction from addition to 3SAT.
Very good question. There should be.

You should email them.
Some PPC, a lot of link building. Our strategy was to rank well on Google and rely on organic traffic to grow. I am not sure if that was a good strategy to start with but it has paid off handsomely (although it took a while...). Having free visitors delivered to us everyday by the search engines is quite an asset to have.
> Most solar panels come with a 25 year warranty.

How much of "rated power" does that warranty cover?

Suppose that the power output drops 20% by year 29, what will the warranty pay? How about if the output drops 15% by year 20?

It's unlikely that the warranty will pay full replacement value. Most warrantys cover pay value, which is likely to be fairly low for 20-30 year-old PV panels. And no, they won't fix if that costs more than the "value".

I am indeed arguing that Facebook's very existence and the effect it had, insofar as it greased the wheel of Internet use, is a huge part of why Reddit can exist at the scale it does. Reddit is a better-organized web forum, which are not new, and maybe by its own design merit does it succeed. This, I do not argue with. But I do not think it could exist at its current or anywhere-near-comparable scale and level of success without the social network effect.

Tracking is only helpful in sunny areas, certainly not in a cloudy place like Seattle.

Given the rate solar PV panel prices are falling, however, PV in Seattle-type climates (and in Germany like the OP discusses) may be economic much sooner than many people expect.

> Ignoring maintenance, you get $25,000 worth of electricity for an initial one-time investment of $700. Though that's production cost, and excludes installation, maintenance, etc. so likely multiples of that at retail.

Something is wrong here. Installation is maybe $3k. The typical retail markup is 2x. So, let's call it $5k.

25 years of 4,000kWH is 100,000kWH. $25K means $0.25/kWH, which seems high.
Your comment presupposes that advances in mathematics are more important than advances in social communication. Is Mozart less iconic because his achievements were in music?
Web 2.0 trendy? When I think of laptop stickers I think of the ximian monkeys on my old 486 laptop.
I recently interviewed with Groupon just a few weeks ago. The people I met were all pretty laid back. It looks like the developers are treated nicely. Most of the people I talked to seem with the current state of things. Most of the site with the exception of some backend stuff is handled by rails, so you can imagine how much of a mess it must be to have 200+ developers writing feature after feature all on the same rails application (yes, I realize I am exaggerating a bit). I did get some impressive numbers on the number of deals that they have and some of the growth that they are experiencing, so that aspect was a bit impressive. I just wonder how many people are going to try to escape post-IPO.

Tomorrow’s Web - A Slide share by Rob Hawkes of Mozilla
I am amazed that someone would write so much so thoroughly yet completely miss the point that some people don't give a damn about UPP or identity. Want to know what my reputation is? Too bad, it doesn't exist. Excepting the handful of close, personal friends, everyone who communicates with me is forced to judge me based purely on the merits of what I am saying, and not any sort of accumulated respect.

That's exactly the way I like it, because it's honest. If I say something stupid, I want people to say it's stupid. If I say something intelligent, I want them to say it's intelligent. The concept that I would be dishonest or hold my tongue instead of saying exactly what I thought for fear of what the listener would think of me is little better than lying to their face. The world would be a healthier place if everyone was called out on their stupidity, every time, by everyone there.

Anonymity enables honesty. Rigid identities are for people who are afraid of what they might hear if there was nothing protecting them from the truth of other peoples' thoughts.

Do you think this comment is the most ignorant, idiotic thing you've read today? Then tell me so, without being influenced by who I am, or dissuaded by anything I might do or think in the future. I welcome your honest opinion, for I know it is based purely on what I have said.
Since solar is less than 1% of US electricity generation, it is unclear why you interpret this to be "a slavic devotion to a specific technology".

Solar is the ultimate option of energy independence, since as the OP discusses, 30 lbs of sand turned into solar cells will power a house for three decades or more.
Personal banking: Fidelity Investments

Assuming you don't care about (or can work around) the relatively few services that require going to an actual bank branch (e.g. free notary public, cashiers' checks, ...) their "Cash Management" accounts are wonderful. A monthly allowance for ATM fee reimbursements, direct deposit (of course) and image-based check deposit, free transfers in and out, alternative investment choices for your cash balance (e.g. municipals), and (almost) no fees.
I don't question myself very often, I don't see myself as super smart or super competent but I believe that you can do anything you want as long as you are willing to pay the "price". Sometimes a project may demand from you more than you are willing to give, but rarely a project will demand the impossible. So I guess I never questioned if there was anything I couldn't do, but I was very aware there are certain things I wouldn't be willing to do (black-hat SEO for example).

We have pivoted at least twice but we did so by small steps, we never sat down and decided on a brand new direction. Instead we analyzed the data and changed the incentives in place to guide the community to one direction or another.

Regarding keeping the business alive, we didn't quit our day jobs right away and for the first couple of years we treated more like as a hobby. Then eventually we started supplementing our income with it, etc, you get the idea.

> Honest question: why is it worth the premium - and loss of user customization - to be so thin?

Well, we're talking about Air style laptops here. Extreme portability is kind of the requirement, and thin helps.

I also see the loss of "user customization" as a good thing, I want the laptop to be "fire and forget", like those distraction free writing environment.

> Unibody: Debatable if that is even a good thing. I searched in vain for studies that show a unibody laptop is sturdier or more durable; do you know of any?

No, but I've owned many plastic laptops --including Toshiba's and Apple's-- and a few metal ones, and it feels obviously sturdier at hand. Remove points of failure, such as joints, is a good thing. I had many laptops "break", or slightly open, at the joints between sides, something that cannot happen in a MBP.

> Shorter battery life

I'm not sure about this. Apple tends to report expected battery life damn accurately, while other companies are off by 20-30% or even more (based on tons of reviews I've read). Could this be the case here?

> -Less RAM (4GB versus 6)

The specs on the cnet page say 4 GB, ??

> -No dvd drive

I think this falls in the "no floppy disk" category though.
I think the reason there's a sudden interest/spike is coz it's it's strange/new/funky.

It's kind of similar to the "You should follow me on twitter." which supposedly inc. ppl. doing it. But I think the initial increase was just interest coz of the strangeness/quirkiness of the statement. Once everyone starts doing it, it will loose it's uniqueness flair and ppl. will just start liking/following as they normally did.
What about the person who earned $100k and loaned $10k, leaving them with $90k?

"Fractional reserve" doesn't help here because if I'm spending the borrowed money, it isn't being kept in the bank by either the lender or the borrower.
Your units are off there. Watts are a measure of power (joules per second), not energy (joules).
Paul are you going to comment on the following?

People like Milner and others associated with Russian oligarchs spend lavishly because the money they have came with no sacrifice on their part. The sacrifice came from all those miners working in subzero temperatures in the Kazakh steppe for kopeks a day, their bodies broken down prematurely, with the share of wealth that was promised to them stolen away. And instead of those who betrayed them being brought to justice, they instead depart to the West where they are greeted with applause by those who mistake cunningness with intelligence.
Um, you're my hero. Not sure if you know that you have admirers out there. After reading about you, I became confident enough to write a Lisp-based DSL for describing and valuing financial derivative contracts. Yes, those. It directly and indirectly made me richer than I've ever been (that's not saying much, though.)

In the end, we moved to Python for similar reasons.

But you inspired me. Thanks.
This is a great story written by one of computer science's greater minds. R.I.P. John McCarthy.
When you say "learn some coding yourself" exactly how much does this entail?

For instance, I know HTML and CSS. I am slowly learning Javascript. I am fairly confident I could learn to code the front-end in a reasonable amount of time.

Is that "learning some code yourself" or do I need to know more?

If I need to know back-end (or should), how extensive? I only ask because while I'd love to really know how to code.... I know it'd take far too long to become truly proficient. So, I'm just trying to portion my time out effectively because I can spend my time on my business in a lot of other ways as well. I don't want to spin my wheels learning to code when I'll never truly be the technical guy who you go to for code (I just don't have years to learn). I just want to learn enough to be respected and know what's going on.

If anyone could give me a good resource to attain that level of knowledge, that'd be great. There just seems to be so much I could learn and if I go the wrong direction, it could be (somewhat) a waste of time and I want to avoid that.

Thanks again for the reply.

Thanks. I will have to get 'The Rational Optimist'. Matt Ridley's book 'Nature via Nurture' impacted me a lot when it first came out.

The online course 'Physics for Future Presidents' taught me a lot about how to evaluate energy sources. I would recommend it to anyone interested in learning the physics concepts behind many hotly debated areas, whom currently has little knowledge or exposure in this area.
I don't think you are wrong in your overall point. My post was an analysis of the social evolution of self-expression. That was its direction. Your points relate to the actual utility of having no identity. The merits of your points (while anonymous) exist, but I would argue that they could not exist if not for the experiences derived under a rigid identity, perhaps not even without the experiences derived from having an identity on the web anywhere. How do you know that you care about identity or UPP or not if you did not experience both the "have" and "have not" have not at some point? Your opinion comes out of the in-between, and knowing both ways.

Edit: upvote for your throwaway, new account to prove your point. I imagine it would not have preceded a real account that you care about.

The only times I've had difficulty solving a fragmentation problem was because a GC was involved, and rewriting the code in an effort to trick some enormous black box into doing what I wanted was a lot more difficult than just writing code that did what I wanted in the first place. ymmv.
In many cases, using Parse means you don't have to run your own backend servers at all.

Even if you use Parse in conjunction with your own backend, it can be convenient to add new functionality without having to touch any backend code.
Right, but people who don't hate women, children, and possibly themselves, don't really have that reaction right off the bat.

You are right in the sense that you should not have children, less because this is a reasonable and healthy outlook on life and more because if you believe this bullshit and live your life by it, you aren't fit to raise kids period.
OK a bit harsh but speaking from experience:

You can adjust the surrounding (yes, it does help) but nothing is going to get done till you make the decision and the plan to do it. Clean you room, it'll work for 5 minutes...maybe even a day and then you'll be back to watching shows.

1. Clean your room.
2. Make a to do list. Give everything on the list a time and a location for when you are going to do it. Sort of like making an appointment to do it.
3. Decide that you are gonna do it. Don't pressure yourself and don't stress yourself of why its not done yet, past is history. Just think about what you are gonna do, when, where, and how you are gonna do it.
4. Take it one step at a time. What are you doing right now? Is there something better you can be doing? Every time you go to Netflix, close that tab. EVERY TIME. Then start with the work you need to do. Again, close that tab.

You are the only person who can control what you do. Most realistic thing I can say is take it one step at a time. Don't worry about where you are headed or how you are going to be so much more efficient in a week. Just focus on right now and all will be good.

Get it?

Now go do it.
It's interesting to see how far bikers would twist the truth to justify running red light and stop sign.
