There are several other systems (including God) I still really want to evaluate, unfortunately I just haven't had the time to do so yet. I'll add a note to the post saying this isn't meant to be an exhaustive list yet!
Pumping is fine. Recognize that going to work can be a huge source of stress for Mom due to the degree to which staying at home is often promoted as an ideal for women. Men are not immune to this either, of course. Twelve years on, it remains a source of misgiving for my wife. But at least now it crosses my radar more frequently.

Your wife is the primary caregiver. Be patient. Listen instead of trying to fix. Taking care of her is the hard role with which you have been tasked.
A decent GPU would still be plenty profitable even after a 3x difficulty increase. For example the HD 7970 (about $400) currently mines $130/month, with electrical costs around $15/month assuming a worldwide average rate of $0.10/kWh, making a $115/month profit. After a 3x diff increase, this would turn to $45/mo revenues and $30/mo profits.

However this 140 Thash/s of Avalon chips is just a fraction of what is about to hit the network. All ASIC vendors combined, plus future Avalon deliveries will push the difficulty far more than 3x higher in the next 4-6 months.

Current ASICs do 150-200 Mhash/Joule (at 12V). Much better than GPUs topping out at 3-4 Mhash/Joule (at 12V).
Is it possible that the guys you outsourced it to could just make their own version and put it on the store? I haven't read a HN article titled "How foobar consulting stole my iPhone app and re-branded it as their own"
yeah, me too, and LOTS of my personal anecdotal evidence is 180 degrees opposite to yours, which is my point. you are describing the upper elite of our demographic group (of which i am also a member) as somehow the mode or the mean for 'asians', and i am cautioning you against that.

it's really easy to be 'proud' of achievement and cheerlead and go "look at us aren't we great" but you need to be aware of selection and survivor bias, especially in the context of your elite east coast schooling which you prattle on about so boastfully.

during my life i have known plenty of underachieving cokehead rich kid asians and struggling yet intelligent lower class inner city asians.
It was a pretty big deal. I ran some queries against some intraday data of a proprietary market index (kind of a cross between the S&P 500 and Russell 2000) and it was the biggest one minute drop (at -0.56%) that I found within the past year.

For comparison, here are the top 5 that I found since 4/23/12:

(1) 4/23/13 @ 13:10: -0.56%
(2) 8/1/12 @ 14:14: -0.45%
(3) 11/29/12 @ 11:41: -0.44%
(4) 6/20/12 @ 12:33: -0.38%
(5) 12/31/12 @ 13:47: -0.35%

As best as I can tell from the news on those days, (2) and (4) were related to Fed announcements and (3) and (5) were related to the fiscal cliff.

Though in our defense, there are also plenty of times when the numbers are wrong and journalists are right.

After performing a basic checksum, we contacted the UN to get a clarification on their firearm-homicides report discrepancy (their A + B should have been equal to C, but wasn't in some cases.) Their response was to basically manually correct column C without ever explaining why it was off. That shook our confidence in their collection and analysis methodology.

State department nonimmigrant visa statistics for the past decade has plenty of numbers for T-2, T-3, T-4, T-5 visas (about 1,500) but only zeroes for T-1. Problem? Description of "T-2" through 5 is "Spouse of T-1", "Child of T-1", "Parent of T-1" and "Unmarried siblings of T-1". So if these are dependents of the visa holders, what happened to T-1's? After pursuing this, we received no comment and hit a dead-end. Somewhat understandably, as T-1 description is a sensitive topic: "T-1: Severe human trafficking informants."
If you're interested in how this works from a behavioral standpoint, this is a very interesting study:

My setup is influenced by my primary language which happens to be c#. This tends to dictate visual studio but to answer your question, I also use webstorm and sublime text. In short I use, and like to use, IDEs with code completion. In addition, I maintain resharper for all of my visual studio versions. Multiple IDEs seem to enhance productivity so I am willing to use whatever IDE helps me be a faster programmer.

it was not DP, but worked quite well, because some of the conditions were eased. the product quantity was unlimited, so as many products as needed could be used. we basically needed to fill the space with as few products (thus dimensionally larger) as possible to minimize the installation work.

it ended up starting out greedy, taking large panels first and adaptively backtracking when the current size could not be placed. if by the end of the iteration we did not reach a minimum coverage area, we would backtrack and remove the last significant size panel and fill it with smaller ones. it didnt get us the "optimal" solution but it was fast and more than sufficient.
I think either of them would rapidly become useless if the company shut down -- if it's not being kept updated, the clients will cease to work on newer OSes, etc. I wouldn't worry too much about the differences.

Maybe both BT and AeroFS should help customers mitigate that risk by committing to open source their code if they shut down. AeroFS has a revenue model, though, so I'd be less concerned about them shutting down this product.
Well, do you use one programming language for every project? or do you match the tool to the problem at hand? I guess if you'd use the same language for Big Numbers that you would use for Language/Text Processing that you would use for Kernel memory space, then you would only really need one tool set, however I prefer to match what tools I'm using to the problem at hand.
It's true, stuff like this was covered with free sample code in Game Developer magazine 10-15 years ago.

OTOH, realize that many readers here were probably not programming then.

Programming is the archetypal field where everything old is new again. The antidote -- dig up all those 1-2 day projects you did 10 years ago that you think are stupid / too simple, and re-package them for the kids.

>> Are you talking about intuition numbers, or random numbers? They are fundamentally different things.

> Not if your intuition is based on random feelings and thoughts instead of "empirical research".

Actually, "random feelings" and "random numbers" really are different things. A random feeling occurs in the context of a particular individual's possible spectrum of feelings, a small subset of all feelings. But by definition, a specific random number must spring from an infinite set of random numbers to meet the technical meaning of "random".
Could you maybe say a little more about what future projects will be, and/or offer an email list? I'm... curious, at the very least, but I don't really want to follow on Twitter, I just want to see the next announcement, and then perhaps the one after that, and take it from there.

There's roughly 270 million guns in the USA and every day about 270 shootings. A ratio of one in a million.

I'm not sure how many pressure cookers there are in the US, probably in the tens of millions at most. I can't find any data on how many injuries are caused by them, but there'd have to be 10-20 incidents per day for it to measure up to guns in terms of injuries per object.

The most common injury from a pressure cooker is a burn. There are about 100 burns requiring medical attention in the US daily (http://www.ameriburn.org/resources_factsheet.php) and it's unlikely that 25% of these are caused by pressure cookers given the wide number of causes of burns.

"The simplest being to short a basket of stocks that are going to be affected and cover the shorts with buy orders."

Don't even worry about the basket thing. You would just use SPY (S&P 500 ETF) or ES (e-mini S&P futures). If you can predict how far it will drop ahead of time (a big if) then the strategy is, as you have said, to leave resting buy orders at the bottom of the dip. You don't need to short though, you could just unwind when the position when market bounces back.

OMG You can't say that.

There now that is done, this needs to happen. Being professional means accepting the things you can't changing, and changing the things that you can. Being professional is about being a real profession, getting paid like it and delivering value no matter what you are doing. Ping pong tables, red bull and casual dress codes aren't perks for professionals because they know that they can afford that by delivering value, they'd much rather buy it with money they earned working their 9-5 job. Being professional means that you respect your colleagues, but still push them to do their best. Ultimately, it is the opposite of what our field has become, and most business people think its a joke (read everyone else we work with). The best technical people I've worked with were real people, with real hobbies and passions. They didn't sit behind a desk and have "cool" projects but rather they did excellent work, went home to brew craft beer (or whatever), and had real stories/experience and had lived real lives. I don't honestly give a shit if you wrote an operation system or a programming language if you are intolerable to work with or just a plain uninteresting person. Being technically able to great for technical jobs, but I'd rather hire a professional that gave me 8 hours of his/her best, than some guy who was boring as hell but gave me 12 hours every day (including weekends).

Yes you are correct. Edited the text. Not sure where my brain is this morning. It's still pretty cool to see the data, no?
It seems to me (you may know more about this than I do) that one can design a memory system to make latency for sequential addresses accesses arbitrarily small and this is mostly how (G)DDR(n) have improved overall performance. But random (row miss) accesses don't seem to have improved much.

From early 1980's to early 2000's, DRAM latency went from 150 to 50 ns and has stayed around there since. That's 1-2 doublings of performance in that parameter in the last 30 years, compared to who-knows how many in transistor size and speed.

Still, Intel knows what they're doing and I can see a place for (yet another) spot in the memory hierarchy before the CPU resort to off-package DRAM.
Think like systems administrator. They've gotta have a rocket engine and a nav system or its not much of a 1st stage. However adding parachutes, airbags, etc, is new systems. Which means much lower reliability and higher expense.
I work at a fund and we discuss this Ad nauseam:)

There are a few problems with this.

1) Forget execution and settlement risk, assuming you can get away with it, can you really make enough to make it worth your while.

You only get one shot at this, how many times can you anonymously crater the market?, and if you get caught you'll never trade again so you need to make retirement levels of money on this one "trade".

2) Execution risk. Assuming you've got your short butterfly setup so that no one will know you now need to unwind your trade in a matter of milliseconds while making it look like you are reacting, rather than knowing this event was coming.

Part of this is that like you said you'd do this over a basket of stocks. Looking at a butterfly option layout in wikipedia it seems pretty simple. Trying to get out of 30 or so of these trades in under 100 milliseconds isn't.

3) Settlement risk...
You'd' be trading across multiple exchanges all with different timings and liquidity. There is a good chance that your trade gets busted by some but not all exchanges which means you go partial fills all over the place and you might end up partially short and long when all the accounting is done:(
Instead of shorting high, they could have just bought a bunch of index funds right in the trough. When "everything" goes down, "everything" is going to go back up.

Conveniently, you wouldn't have to hold any positions in advance, so you'd appear to just be a player who figured out the non-veracity of the news quickly and took advantage of it to beat the market. You'd also not have to sell right away--you could hold onto the positions indefinitely, if you liked. The only problem is predicting the exact inflection point of the drop (i.e. the best time to place the buy order)--but I have a feeling people might be "predictably irrational" in this, and fake-news stories about easy-to-verify facts might have a regular/well-known half-life. This is classic "insider trading", just applied to a whole market instead of an individual stock.

The only advantage of shorting in this case, I think, is if you didn't have the capital to actually make the money you wanted--you could do the shorts naked.
On the bright side, SpaceX is so economical compared to NASA's past methods, that if it succeeds, we will all benefit. So what might be characterized as theft at one point in time, might eventually be seen as a great investment.

Only time will tell.
Oh, get over yourself. If they re-tweeted it immediately, then went to get more info on it, found out that it was false, and then apologized/deleted it, who cares? It came from a particularly reputable source, so simply clicking one "re-tweet" button does not a fire-able offense make.

I'm glad to know that you've never made an assumption based on authority, a minor mistake, or even taken a shortcut in your career, though.

I was under the impression that this was a paid app. How does it generate so much revenue while still being free?

I signed up for future posts (extremely well-placed sign-up form by the way!), but I didn't see a description of in-app purchases or other revenue model as a topic for a future post, which is why I ask. I am also using Android.

Yes but shorting the entire market isn't difficult at all. And buying and selling a position in a matter of minutes also isn't difficult in modern times.

It's the modern equities market -- lightning fast, and not to the benefit of market stability or the average investor.
Getting a sleep pattern set is absolutely critical the first eight weeks. We have an almost 3 year old (she) and a 9 month old (he). She was set at her 3rd week and him at his 4th or 5th. Both were non-breastfeed but are months ahead on all milestones. Declare a night time regime and follow it strictly. Say 9PM is when you want them to sleep. At 8:30PM have a little one-on-one with the baby. Change their diaper for the night, put on PJs or night gown, make their bottle for the night. At 8 weeks they should be at 4 or more oz. We've had our son at 6oz since about 3 months. Mix the breast milk with a scoop of rice-based formula or even a baby rice cereal. The rice starches will naturally take longer to digest, keeping your baby happier and fuller longer throughout the night. Enfamil, Similac, and even store brands from Target, Walmart, and Sam's Club work well. Talk to your doctor about setting a sleep pattern as well.
I never applied to YC because of the small amounts. First of all, if I'm going to ask for money, I only want to do it once. Which means I'd prefer to ask for enough to get to profitability, not just enough to get to another round. (Granted, you'll raise that A on better terms with YC social proof.) Second, if we assume a 4-year vesting cycle (which, I think, should apply to founders as well) then my being there already puts the valuation at $1.5-2M (because, while I wouldn't get $375-500k on the normal wage-labor market, I'm working 2+ times as hard and taking lots of risk). Scale that up based on how many other founders there are. So for me, it's not a good deal. If you're 22, I think it's probably a great deal.
You don't need to time it, do you? If you have resting buy orders the market is going to come down and hit you at a favorable (to you) price. You can close the position when the market rebounds.
This project is useless if they don't figure out a way to serve files without both machines being turned on, there is also the problem of syncing with multiple clients beside that.

I see two key use cases that could cause trouble:

1)a co-worker turned his computer off and went home from work, the syncing couldn't complete even if only a single doc was left

2)Because there is no central server if all of my coworkers in a distributed team sync with my new shared folder at the same time, it is required that I own a connection capable of supporting that kind of traffic, because it would be almost the same as streaming a video to multiple users, not to mention that I would probably have to avoid to browse the web for pretty much anything else in the meanwhile.

I cannot identify with this article.

Personally I know that my estimates are wrong before and after I make them and I never believed any estimate that I made ... I only make estimates because on every project I worked on, either managers or clients wanted those estimates. So it was for their peace of mind.

On the other hand I always make estimates good enough to have something working, like a proof of concept, because in case the shit hits the fan, you at least want to show the client or the manager that some progress has been made.

This is yet one of those articles that speaks about the pitfalls of the Waterfall model, hinting on the virtues of the various Agile methodologies and it's kind of nauseating. On one hand I feel some arrogance on the part of the writer, on the other hand it reminds me of how awful consultancy work is, because consultancy only works well when you're doing the same thing over and over again.

My favourite development methodology is easy to explain. It's a simple cycle: hack <-> ship. I also lie when giving estimates.
What I am afraid of is to become crippled by moving around too much, never mastering a single tool. I switch between different languages multiple times a week, but I guess if the features a certain editor/IDE adds are so great, they might add more than me knowing everything about it would.
I am very intrigued by the idea of "let them cry to sleep". I will talk to the pediatrician about it but does this really work ? Also does it harm the baby in any way ? Honestly, 2 mins of her crying makes us get up and take her in our arms.

To be fair, that was his first day and he was needlessly swearing trying to pronounce the guy's name right after not checking to see if they were live, and then completely fumbled once his co-anchor turned it over to him. I think it was completely reasonable for them to fire him over that - no one would have taken him seriously afterwards. Also, if you look at his actual written news reports on that network's site, they were littered with misspellings and grammatical errors, and the background on his official Twitter has vulgar statements that just don't line up with the profile picture of him in a suit. He's all-around unprofessional and that might have been the icing on the cake.
I think your analogy is a bit flawed. The local Boy Scout troop would love to have such a promotion if the rewards were achievable. 10,000 sandwiches to earn one free sandwich is obviously ludicrous but if it was more like "When the group buys 100 sandwiches, Subway will cater your next pack meeting", then the kids/parents would be all over that.

Now you've transitioned me from skeptic to potential client.

Yet, my reasons are for evil purposes. Could I not feed countless lists of websites to the Professional version? I believe I see support for proxy(ies). In turn, could I not sell these lists of vulnerable sites to some market?

Understand, my position comes as a product of prior environments. This is basically a script kiddie's paradise. Could I use Google tricks to find lists of sites that use all of the softwares mentioned in your spreadsheet, set out a list of 500 proxies to do my bidding, and reap the black-hat rewards?

I could be a good guy, find the vulnerable sites, and use the list to WHOIS every domain and email the owners with Perl/Python.

If you give me a product that can brute force my bitcoin wallet password, but for an extra $1000, I can brute force unlimited bitcoin wallets, you attract a certain breed.
The problem is that you can end up with larger latency over the network because it still takes a fixed amount of time for nodes to communicate. Even with a 1TB/s link between nodes you can still have a good 30ms between them all adding even more latency. That can be mitigated somewhat by a good protocol that can manage that latency properly (e.g. not blocking while waiting on ACKs and such), it can still end up with far more latency than a few large disks would be (even better now with SSDs). That said I do imagine that some datasets will benefit from this kind of topology (I can imagine that geospatial stuff will do well with that, since you can locate physically close things on a single machine and reduce the amount of talking needed).
