> Living in a mobile home is actually pretty decent. It's generally going to be nicer, and much more private, than living in the type of apartments that would be within range of someone at that income level.

It often isn't, but you're right that it definitely can be a nice place if set up properly. There's a mobile home community near me that is strictly for retired people with no juvenile children in the house; it's safer and cleaner than even some of the "nice" subdivisions in the area.

There's also a great place I stayed at on vacation in Florida several years ago. It's set up as a combination mobile home community and beach house rental business, where owners can lease their mobile homes via the management company to weekly beachgoers. Some owners live there year round (mostly retirees), others live there seasonally, and yet others just use it as a vacation home for a few weeks a year, and lease it out the rest of the year.

The military spending thing is a bit of a canard. There is great value in US military hegemony, and that value is not experienced only by the US. There are downsides to it, but compared to having Russia prime in Europe and China prime in Asia it's the least bad option.
One problems I have with most cryptographic libraries, like OpenSSL and NaCl as recommended here, is their extensive use of globally mutable variables. I can't understand how that seems a good idea in 2015.
I was under the impression that Y-Combinator pretty much doesn't accept lone founders. Maybe I thought especially if I wasn't able to build my idea myself.

I've tried looking into meetups in my area and there aren't really any active ones. I have a pretty wide professional network here locally and nobody I personally know is someone seems right for the technical and programming aspect.

"According to your thesis, these studies will show that everyone will obtain approximately the same outcome, because in all cases we have controlled for luck, starting position, income, and management strategy. Only the choice of management strategy will have material impact."

No, you haven't understood my thesis at all. You seem to think I'm making some sort of political or statement related to the current economy.

The point us that every gets out a combination of what effort they put in and the decisions they make. For some, born with a trust fund, those efforts bad decisions are easy. For others, new immigrants without qualifications, those efforts are going to need to be huge.

For all, they will get back what they put in. All will get what they want, when you read want as not what people say they want but measured by their actions.

I might say I want to get fit but unless you see me out training you would quite correctly surmise I don't actually want to get fit. Everyone gets what they really want.

Anecdote: When I started high school, we had a teacher in literature who everyone just hated. He was harsh, his tests were hard, the subject was boring, etc. In the third year though, most of us realized that he was very good at teaching, and the things he taught actually stuck. Many years after high school, I consider him the best teacher I've ever had.

He never tried to make himself popular, but he was relentless when it came to teaching. A student evaluation program would have been disastrous for him, and everyone would have been worse off.
Code is a great book. What I think is the most powerful and interesting point is that a computer can be built from (a sufficiently large number of) any component that can perform logic functions.

I stopped reading Nand2Tetris in any great amount of detail and just skimmed the rest after I saw that it confused Harvard (separate code and data) and Von Neumann (combined) architectures.

+1. I wish every site was designed first like this, then enhanced with CSS, then enhanced with JS. That is called progressive fallback, where CSS/JS is used for the enhancement of content, not the element of the content.

Food, as a commodity, is much cheaper than most people think. The price of rice is hovering around $400 per metric ton. Wheat is less than $250. Soybeans about $400. Pork is about $1500 per metric ton, Beef about 3 times that.

According to random sites I googled, the average american eats just under a metric ton of food a year. Depending on what you eat, you could potentially eat for a year on considerably less than $1000, if you bought food at commodity prices.

The reason we can't buy food at that price is because of all of the processing and handling that goes on between the farmer and the plate. A restaurant is just another level of processing and handling, so it appears to the average consumer that it isn't much more expensive than cooking at home. In reality, it is possible to source food in large quantities and to do all the processing yourself at a significantly reduced cost. There are even groups of people who do this for fun. With the advent of the internet it is now easier than ever to do it.

However, the reason that this is not so popular is that most people in the western world are comparatively rich and have no free time. Most people don't care if they can cut $1000 a year from their food budget if it means that they have to invest 2 hours a day to do it. Many, many families have dual incomes, so even if we say that we could cut their overall household food budget by $4000, they wouldn't do it because they would have to give up one of those incomes.

So, I don't think restaurants have gotten cheaper -- people have gotten richer, but have given up time to get the money.
Silicon Valley’s Youth Problem (2014)
The nonce is the expected thing to tweak, but given current difficulty, it's pretty likely that trying all the nonces will fail. The timestamp can also be tweaked, and the transaction list changed. But miners usually change the "coinbase" transaction (which is the transaction that grants bitcoins to the miners) by putting an extra nonce in there, since there's extra room and the transaction can be modified without messing anything up. This is important in mining pool so miners can do a lot of hashes without constantly contacting the server to request a new block. See my blog post on mining for details of how the coinbase transaction is built by concatenation: http://www.righto.com/2014/02/bitcoin-mining-hard-way-algori...
The ironic thing about that burrito (it's the Austrian Chocolate Burrito, for those of you with the cookbook at home), is that it was designed on a very early version of the system that required significant help from a professional chef. At that point the system was mainly flavor pairings.

This all reminds me of Vibram's and the minimalist running shoe movement. Runner's wanted things to be "natural" because it's "healthier." It sounds very novel. But we didn't respect the fact that we're running miles on blacktop and concrete surfaces.
There's a few cocktail recipes in the system if you know how to haze it well enough. Unfortunately, Watson tends to really like bacon in cocktails as it can easily connect a multitude of flavors (sweet through carmelization, salty through the curing, meaty, etc). It's always a bit of a buzzkill for folks with dietary restrictions. Chapter 7 in the "Cognitive Cooking with Chef Watson" cookbook as a few recipes.
You're right. I've had this saved in my Delicious bookmarks for years. I think it was mentioned in a popular subreddit recently, so here it is again.

As a user of NoScript + Firefox and as a developer of a browser with an express goal of "privacy by default"[1], I am thrilled to see this getting more attention. The more people use privacy features, the more will website developers ensure that their products degrade gracefully when, for example, third-party scripts are disabled. Which will enable even more users to migrate towards a "privacy by default" configuration. And hopefully, this will be a positive feedback cycle.

We haven't released a direct API for Chef Watson yet. However, there's lots of different APIs that you can get access to via the Watson Developer Cloud (http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercl...). Probably one of the most interesting the new Natural Language Classifier API, which we just released last week (http://www.ibm.com/smarterplanet/us/en/ibmwatson/developercl...) - you'll need to have a Bluemix (http://www.bluemix.net) account and then go down to Bluemix labs to get the service.
Or you can go to the beginning of the line, press Control-space (set mark), press Control-e (end of line), then Meta-W (copy), and Control-y (paste).

Early Swift Adoption at SlideShare (LinkedIn)
It's definitely not common these days to send a thank you note. It used to be a lot more common 20+ years ago but these days, it's pretty uncommon from my experience.

But I don't think there's anything wrong with sending a very brief, succinct thank you email to your interviewer(s). And in one case, someone I know got a job at Cisco because she sent a well-written thank you letter to the interviewer, because it put her in their minds before they decided among 10 similarly-qualified candidates. Keep it short and on point, with maybe one sentence about something they mentioned when talking with you. There is definitely an art to writing a 2-4 sentence, non-awkward email.

Personally I think a hand-written note would be weird, I wouldn't do it.
This should be a longer blog post; especially the turnaround is interesting.

I work on the team that designed and built Chef Watson, both the current app that is available at https://www.ibmchefwatson.com/ and the food truck that we had at SXSW 2014. If you have questions about the technology or Watson stuff in general, such as the IBM Watson Developer Cloud, let me know and I'll attempt to answer them or track down the right person to answer them. As it is a holiday weekend here in the United States, if I need to track down someone for an answer it might take a couple of days - so I'm not hiding, it just might take a bit of time.
Firestar Attacks Local Students
I think a lot of people are missing the point of the article. It's not saying that pumping food full of high-fructose corn syrup is this great and wonderful thing that has no downsides. It's pointing out how technology has made food more affordable and accessible, and asking to "go back" to how things used to be means condemning lots of people to poverty. If we want to make food healthier, we need to figure out how to make better food affordable, not try to return to a past that never was.
> I'll ignore the blatant sexism.

Stating a fact or observation is not sexist by itself. The anecdotal data around me shows that the people with food intolerance and I won't eat X because someone in the newspaper misinterpreted a study have a even number of X chromosomes. To make sure there is balance - there is a lot of bronutrition in the opposite direction.

> I have yet to meet a person whose diet choices fall out of the range of rationality

Any person that observes religious restrictions - that is not rational. Also any person that refuses to eat X based on pseudo, improperly conducted or improperly understood science.

> I am vegan because I would rather not have had a sentient animal purposely killed for my meal - and it is a decision I came to after years of thought and consideration.

That will push you only to vegetarian. To go vegan you need more reasons.
While I would not thrust myself to give unbiased evaluations in high school or even at the start of college. But these days, I make an effort to always try and give valuable observations during student evaluations.

Thus I feel like student evaluations should not be discarded, but its a bad idea to have them be the sole garant of teacher performance.

Tech Stories You Should Know This Week
If you're using emacs you can use M-x eshell to open a shell. Combined with tramp (which lets you open remote files via ssh: C-x C-f /ssh:you@otherhost:path/to/file) you can actually avoid using tmux/screen at all. Instead of managing screens in tmux and simultaneously buffers in emacs, you just need the emacs buffers.

If you'd like to get an idea about the different ways people are using Watson Technologies, check out some of the Watson Ecosystem Partners (http://www.ibm.com/smarterplanet/us/en/ibmwatson/ecosystem.h...). There's a variety of partners that aren't listed on our partners page, in particular you mentioned Vacations, so you might be interested in WayBlazer (http://wayblazer.com/), a new company founded by Terry Jones - former CEO of Travelocity.com and founding chairman of Kayak.com.

The big thing with Watson is that it works with people to make them smarter, rather than replacing people. Watson isn't designed to be a single global AI system that will enslave us (well, at least not yet), rather it's designed to be trained so it can go in depth on various topics to make humans smarter at their jobs - whether that's medicine, finance, travel, cooking, or who knows what else.
Yes. It sounds like that was the linchpin. It was an indie app so we didn't have much of a marketing budget other than producing a basic video. Nice execution. Hats off to them.

I think that maybe more accurate for entry level developers. Housing is an issue to work around for sure.

Seattle - Yes (but also quite expense)

Austin - Yes to a less degree

Portland - Maybe.

All of these are great cities with plenty of dev jobs. You really need a strong CS program to build around if you want think about not moving to Silicon Valley. University of Washington totally fits that bill, as does University of Texas- Austin, but I would have to guess that Portland has a good local university (but I'm not familiar with it from afar like the others)

I'm thinking the energy to boil the amount of water which falls naturally on California is about 500 times what the electrical grid currently delivers (300,000 Gwh). Estimating avg rain fall over the state at 15 in = 38.1 cm, so 1.62 x 10^14 liters.

We used to build this sort of thing to blow it up. Now we use a supercomputer... I imagine the goal is much the same just less radioactive, a very realistic "city" where everything from self driving cars and better home insulation to heat seeking drones and urban warfare tools, can be put to the test for a price.
Presumably mv would benefit even more. At least with cp a copy was explicitly asked for.

You put the frame and stairs in a warehouse-style steel-framed building. That saves on some requirements for the housing units themselves.

Many zoning laws also include peak height restrictions, which limit the practical height of such a building to 3 stories. But factory-built homes are usually half the cost of a site-built home for the same usable floor area.

The fallacies here are multiple:

1) the assumption that intelligence can actually be measured (in which case it's really just "analytical intelligence"), 2) the assumption that other types of intelligence are less important, 3) the fact that you can't even measure creativity, period.

I have a 148 IQ (and I'm a programmer- of COURSE I have high analytical intelligence) and I have been consistently humbled by the "less intelligent."

Almost nobody uses those features, useful though they may be.

Yeah, I remember this from Reddit a while back. Everytime I see it I waste hours on it though...
What is this "content" you speak of, that must be funded through advertising? I checked the internet, and have been able to find very little worthwhile ad-supported content.

Given that there are more doctors per capita in each of the Nordic countries than there are in the US, the holding onto a mental model that can't make sense of this would seem to be problematic.

> Random IDs (Was: Use 256-bit random numbers): Remains: use 256-bit random numbers.

256-bit random identifiers are overkill. 122 random bits (as in a GUID) should still be more than sufficient. Size is important for IDs because people whine about the storage overhead. A 256-bit identifier requirement may unfortunately convince some people that it's better to use much smaller, non-random identifiers, and that'd be a shame.
Conflict arises because content isn't truly free. Someone pays of their free time or gets paid to produce by advertising or subscribers. Tools that deliver the content while bypassing payment will drive payment elsewhere or erode the incentive to produce.
I'm not at all convinced. If incurring a bunch of technical debt makes your company rich, then it was worth it, and it shouldn't really be considered debt.
I've never heard of Bangor, Maine before (despite growing up in the US). But Key West seems like a plausible alternative.
> In a system like that, you would have fewer doctors yes, but the ones you have would be the ones who actually want to BE doctors. In the US you have a huge group who couldn't afford med school but really want to save lives as a doctor. Under that system, they could do it.

That's not entirely true. The United States military is one example of an organization that will pay for your medical school in exchange for some of your time. My wife is a physical therapist in the Army and this is how it worked for her. The Army paid for her school and she earned a 1.5x service obligation for the time she spent in school. It was a three-year school so once she finished, she owed 4.5 years of Active Duty service. On top of the school cost itself, they paid her as an active duty officer while she was in school, plus they paid for our housing and subsistence allowance for our family. All in all, she made about $75-80K a year to get her degree, then $100K+ once she was done with the school. It's not some front lines combat thing, either. She works in a normal clinic like most PTs, treating Soldiers and civilian family members and retirees. She's in it for a career so she will receive a retirement pension after 20 years (how many civilian docs in the US get that?), plus lifetime healthcare for her and me and our children until they turn 18.

It's truly an incredible deal for us, and it's available to anyone with the grades to get into medical/dental/PT/OT/etc. school and who can pass a physical and fitness test.

Being worth it doesn't mean it isn't debt, or that it doesn't need to be dealt with.
Do you understand what debt is? Taking out cash loans is essential for many small businesses and startups, and it's worth it, but it's still debt. The bill comes due eventually.

The point isn't that you shouldn't accumulate debt (doing so is impossible in the first place, generally speaking) - it's that you need to be aware about it and make plans to pay it down regularly so it doesn't come due and bankrupt you.

Ask HN: Do cloud providers such as AWS negotiate alternate customer agreements?
Per the AWS Customer Agreement (my interest is in the last line):

(a) Termination for Convenience. You may terminate this Agreement for any reason by: (i) providing us notice and (ii) closing your account for all Services for which we provide an account closing mechanism. We may terminate this Agreement for any reason by providing you 30 days advance notice.

Certainly for someone as large as Netflix, it's not a real worry, but for a lot of businesses it seems like a large risk to have out there unmitigated? Do people execute agreements to get better terms than this or does everyone just ignore it? Everyone I've asked and seems to shrug that it won't happen, but IMHO this is insufficient for a CEO/CTO that's trying go build a company and needs to be proactive with regards to liability.
