A freezer, if you have one is likely to be running regardless of how much food you have in it... it runs more effectively when full, less air to seep out and replace with chilled air when you open the door, so a bit of a misnomer. For that matter, even if you cannot afford to fill your freezer with food at first, it may be worthwhile to fill the space with containers of water (for ice) which again will help offset open/close costs... This doesn't even compare to the fridge portion which tends to have much more open/close time than a freezer, and more likely to not be full. ymmv of course.

Personally, I find it very hard to eat healthy for under $10/day USD, I am full on insulin resistant so am taking in far fewer carbs with a fairly high fiber:carb ratio (well under 100g of net carbs a day), this means more green veg. and a few pieces of fruit a day. It also means I need to get more fat in my diet, which mostly comes from animal fat/protien (about 1/4-1/2 lb a day).. this gets pricey fast.

I can't imagine what I'd have to do if I didn't have a decent income with my dietary needs. I tend to average my intakes over the course of a 2-3 day sweep, some days will be more veg, some more meat... shifting my daily diet seems to work better for me losing weight consistently. In a solid week without bread/pasta/rice/potato I lose about 4#. I'm down about 45# from 8 months ago, with about a 5-10# daily variance (water weight).

In the U.S. a lot of the most calorie dense high glycemic index foods are what is subsidized.
Well, except you really have to be outside to do it.
Those may be extremely popular alternatives. But they are alternatives to something, and that something is LAMP. LAMP is a standard one can count on being available on linux-distros, and it is a standard which makes it very easy to develop something for the internet on. As much as I like Ruby, I would not dare to assume that Apache+PHP alone isn't way more popular in terms of general use.

The one thing though that I count on getting replaced on that stack is MySQL, though the M might stay. If Debian hasn't done that already.
Yeah, the money has to come from somewhere. But the point is, the loss could've been mitigated by making better decisions. The bank has less incentive to change their behaviour when the customer will ultimately cover the cost of their mistake.

Say for example there was a regulation that said banks couldn't increase fees because of theft (as a thought exercise, not a practical suggestion). The 45 million loss would directly affect their profits. Lets pretend this happened on a yearly basis on average, it makes good business sense to spend 20 million a year on security to prevent it happening.

If they can lose 45 million a year but know they can recuperate 30 million by making the customer cover the cost of losses, it becomes cheaper to charge the customer than invest in security.
As a former (beer) home-brewer (hence my HN handle), just drink what you want to drink. I may prefer craft beers, but that's a choice that I'm not going to force onto others.
As for me, I found Spolsky's article lacking, too. But lurking for years on the Unicode ML is probably not something most people do. You learn a lot there, though.
Why don't they add another pilot? 2x the power for less than double the weight.
Ordering from an approved supplier with a traceable chain of delivery for equipment used in a space program seems quite reasonable to me. There is a reason that people from the more traditional engineering disciplines (aerospace, chemical, civil, mechanical) are so anal-retentive about "proper engineering guidelines." It's because they deal with things that blow up, and when they do blow up shoot turbine blade shrapnel all over the place. Nearly everyone working in these fields has some story about how a little screw up in one out-of-the-way component caused some epic disaster that involved fire.

Yeah, sure in this case it was just some screws on a plastic housing and there was a 99.999% chance that everything would've been fine. But you don't want to make exceptions, because if you play fast and loose here and there, eventually all the prudent practices go out the window and you're no better than the software guys.

It pains me that so many people are talking about the freedom to distribute these designs without discussing the negative impact that "3D printed weapons" will have on the widespread acceptance of 3D printing in homes and communities.

I'd much rather see the world embrace 3D printing than fear it. Talk about "what we can print" after we all have access to 3D printers. We aren't there yet.
It is. I'm planning to put out more stuff like this over time. Any feedback is welcome!

The primary purpose of Gmail seems to be get people to sign in so that all their web searches can be tracked by Google across computers to users' Google Accounts so that ads can be targeted, not to mention to force Google+ on users. I think it is pretty successful at making people do that.

50 Shades of Demo
What communities are best for discussing mathematics when learning? As Jeremy describes in another post (http://jeremykun.com/2013/02/08/why-there-is-no-hitchhikers-...), it's really difficult to learn math without talking to other people. StackExchange seems alright, but are there other good places to ask questions? Maybe an IRC channel?
Ah that explains it. I was indeed selected... I assumed that everybody had it when it came out of beta...

Seed packets are $0.10 at The Dollar Store this time of year.

Yeah, that's a really easy mistake to make. Happened to me too, last year. "Zuchini seeds ten plants for ten cents? I'm going to save SO MUCH MONEY!" I thought. Then I realized: A box big enough to grow a single zucchini plant in: €7. Yep, big planters are crazy expensive. Enough soil to grow a healthy zucchini plant: €5. Yep, you do need the entire bag if you want actual fruits instead of a pretty but useless flower.

Time to drive to the garden market, buy planters, plant them, and water the plants: Maybe two hours altogether.

So now you're at €12,10 for, IDK, maybe a dozen zucchini over the season. Not really a steal, but hey, organic food! Still worth it, right?

Then my zucchini got bugs and died. €12,10 and two hours of effort wasted.

"Yep, that happens when you grow vegetables inside. Should have put them on the balcony", my gardener friends said, nodding wisely. Know many poor people with nice big south-facing balconies?

I've in the past also failed miserably at sunflowers, and let's not even talk about the slow miserable death of my tragic attempt at salad. Now, I keep trying to grow food because I have the time and money to waste, and a shed to store all those big planters in during the winter. But if I were trying to cheaply feed my family, this sure as hell isn't a hobby I could afford.
That is quite clever, I didn't know that you could do that. I don't know much of our integration of FontAwesome, I do mostly backend related stuff, and argue icons with the frontend guys :)
See my other comment in this thread for more detail, but why do we keep referring to the cable industry as some monolith? It's not true and obfuscates quality analysis.
Master Developers: Addy Osmani
I must have read the article differently from you. I sensed there was a positive attitude towards him, but I didn't feel they were trying to say he had proven the theorem or was so brilliant no one else could grasp it. On the contrary, it seemed like they were saying "This person has been brilliant for quite some time, but this 'proof' seems entirely nonsensical even to the experts in the field."

So to me, that read more as, this is a curiosity that has a deep and interesting past and an even more interesting present.

> I wanted to present an alternative possibility which seems to be disregarded at the moment

That is entirely fair and valid. I just misread your comment as more along the lines of "Does no one else see how obvious it is that this guy is crazy?!" My fault.

> On the topic of Perelman

Yes I was already corrected. I couldn't remember with certainty whether he did or didn't. I thought he had, but then what I remembered about his personality made me reconsider that.
People are complaining because the author ignores his own take-away: "Different time, different industry."

All of this "agile," "free for all," "start up" cuteness is okay when you're dealing with software, which generally only ever results in frustration or at worst lost profits. The standards and practices in industries where things can go wrong in epic, expensive, and dangerous ways is obviously quite different.

Money wise, it's good since it saves them a lot of money in the long term, but I still wish all government institutions would switch to open source software wherever possible.

And by wherever possible I don't mean that some users might be "inconvenienced" by some menu change. I mean when an open source alternative actually exists.

But even then, if the government is willing to spend money to get people or companies to build that software, they should make it open source after that.
Why not just use this:

Every time datomic is brought up, people always chime in with this whining about it being closed source and I just find it sounds entitled and petty. It makes it seem like with enough people agreeing with you and enough upvotes or whatever, you think the releasers of datomic might reconsider and open source their code.

This is the same person/people that released clojure to the world (as open source). It's not like they're a company with a history of closed proprietary software, they are fully aware of their options, and I'm sure they have their reasons for keeping it closed. Aren't they entitled to do whatever they want with the code they produce without frowny faces all over the comment threads?

But they are alternatives to something, and that something is LAMP.

This simply isn't true. Web development is done in many languages, and while the P in there stands for several of them, it's entirely inaccurate to suggest that any or all of them are somehow a default value deployment or development.

Web development deployment environments are not the sole purpose of Debian, and the purpose of non-'P' development languages is not to serve as potential but perpetually-sidelined alternatives to this arbitrary default.

A story about the team's efforts from back in Oct last year:

Generally, from what I have read/heard, the companies make deals amongst each other and with municipalities to be the sole provider for an area. If this is correct, then the companies are actually working together, just not for the benefit of the consumer.

A lot of professional mathematicians are considering the idea that it might all be nonsense. Popular writing on anything technical is not always representative of what's actually going on behind the scenes.

At the same time, it's important to check the work rather than just dismissing it. Mochizuki's work isn't totally original - a lot of it is derived from existing theory. So it should be possible to validate it despite the complexity.

It's true that serious breakthroughs from individuals working alone are rare, but they are not unheard of. The real test is whether or not this work can be adapted to the rest of mathematics (or the other way around, perhaps).

As pointed out in 3.) the mortality hazard h(x) does not increase exponentially at very high ages as it does for ages 30 up to let's 80 or 90. Until then the Gompertz-Makeham hazard h(x)= alpha * exp(betax) + gamma approximates adult mortality very well. At higher ages mortality begins to decelerate and, most likely, reaches a plateau at about age 110.
References:

1) Parametric models for late life mortality:

A useful mortality model, which has a logistic form, is: h(x) = (alpha exp(betax))(1+alpha exp(beta*x)). One can also add an additive term, often denoted as gamma or c. Please see for a comparison for late life models:

Never do that, say NO.

Don't try to justify it. Don't lose your time with this person, don't lose emotional energy.

It is one thing to be efficient, another to "look efficient". You can be not efficient but look like you are or the contrary, specially when your client don't have a clue in software.

The reason this customer wants the video is to go against you, as you said, he already does not trust you.

When you do, he is going to go and say: look, you are not working 80% of the time, so I am paying you 20%. Probably he already have plans for doing that.

He probably does not have the money, or the organization changed plans and don't need the software as much as when the agreement was done and wants to backpedal with any excuse.

Many people who live payday to payday will be the types of people who if they had there pay doubled would adjust into the same payday to payday model.

In general these will be young people who are out to enjoy life and whilst many adapt a more moderate balance lifestyle, there are always some who carry on.

Certainly with the lack of incentives for savers, this certainly does not help motivate people and why should it.

What I would be interested in is a graph of fiscal behavour done per age groups and fiscal income. Also if they are single or married or have children. Then I believe you would see a more measurable trend.

Though it is worth bearing in mind credit card companies prefer people who live like this as they make them more money than not and with that is it a testiment to how well credit card marketing is actioned I do wonder.

Mutable data structures are a much more accurate abstraction when it comes to how computers actually store data in memory and on disc -- I don't think you can reasonably call them "flawed." A (properly-implemented) mutable memory structure will have better performance characteristics by definition.

Don't get me wrong, I like immutable data and I use it over mutable whenever possible (Clojure is my favorite language), but to call it "flawed" is an overreach at best.
How are quantum internets built?
I'm not at all sure about this. Very possibly for cargo carrying trucks, they have different design tradeoffs.

But as I understand it, "high speed" WRT to accidents starts at about 35 mph, which is a speed at which, if you come to an immediate stop, wearing the normal shoulder and waist belts, your head will hit the steering wheel with enough force to cause serious injury, unless an airbag prevents it.

Any reasonable governor is going to be way above that. According to a [citation needed] Wikipedia item (http://en.wikipedia.org/wiki/Governor_(device)#Trucks_.28HGV...), the EU governor speed is 90 or 100 kph, 56 or 62 mph, which sounds plausable. This http://www.usroads.com/journals/aruj/9803/ru980302.htm indicates those speeds are quite lethal.

Keeping people driving for longer periods of time is also going to cost lives....
NC attempting to ban the purchase of Tesla cars.
I agree with your general principle. However, Boston is purchasing a service and not a software product. There is a lot of overhead and expertise needed to purchase and maintain the machines that would run any open source competitor. That isn't as big of a problem when going with something like Gmail.
What do revenues have to do with government uptake?
The bill won't have any significant impact on most customers because cable channels won't charge the cable companies any less. If a cable companies has to pay, say, $1 Mio to distribute a channel, it needs the subscriptions to pay for that. It can either sell channels a la carte for a high fee, or sell bundles for a lower fee per channel. But the revenue will always need to be on the same level.
The only difference will be that people who want very few extra channels may get them cheaper than people who want all available channels. But as soon as you want 3-4 channels (or whatever the amount of channels is that the average consumer is actually interested in), a la carte won't be cheaper than the bundle.
Or none will bounce, one or two might get to someone and the rest will be captured and used to automatically mark you as a spammer.
Boxfish scientist & dev here.

Closed captioning does have a lot of noise in it, but we've done a lot of work to tidy that up. We also have the benefit of capturing so much data that the noise doesn't matter as much.

In real-time our systems extract and generate lots of information from the closed captions. Our NLP system identifies entities (e.g. whitehouse, chris brown, amanda berry), does frequency counts and we have some very large graphs of entity co-occurrences (leads to our statistical learning), e.g. Rihanna is commonly associated with Chris Brown.

We do a bunch more analysis on our graphs, including Latent Semantic Indexing (LSI), which helps drill down into quantifying the relationships between entities. Related to that we generate TFIDF scores for all identified entities, i.e. gives a sense of how "important" an entity is.

By combining our large scale entity graphs (both Frequency and LSI) with streams of closed captions we also do real-time topic extraction at multiple time scales, e.g. what is the topic of conversation on CNN for the last minute of conversation, for the last 5 minutes, for the whole program, etc.

Enumerations support iteration, in definition order:

... chocolate = 4
... cookies = 9
... mint = 3
...
>>> for shake in Shake:

...
Shake.vanilla
Shake.chocolate
Shake.cookies
Shake.mint

Python's execution model sez that the class declaration is nothing more
than code that is exec'd in a dictionary. We know that Python dictionaries
do not perserve order, so why is this iteration in definition order
possible, barring modification to the interpreter or dict type ?
