Building OS' is fun. I wish I could spend all day doing it but I've been pushed so far up the stack that I spend most of the time arguing with analysts and preparing documentation...

I've built two so far which were (and I think still were until recently) used in production equipment. One Forth system (all 8k of it) that ran a PLC system and a tiny (16k) kernel for an M68k system that was a router for a modbus-like protocol over RS485.

Nothing x86_64 but nevertheless the most fun I've ever had with a computer.
Most QR code readers (phone apps, at least) will decode the QR code and display the text before doing anything with it.
May I ask your age?
> Though it seems to be recovering somewhat. Ow.

As with most investments, you need to think medium and long term. Barring some kind of final(!) crash, there isn't anywhere to go for BTC but up. Mainstream media and ordinary people are just now starting to talk about it. Stay with your investment, and don't sell before it at least doubled. If it crashes temporarily, that's fine too: chaos is a ladder.

Within reasonable confidence, I'd say: Whatever you do, do not sell at a loss. That's the moment when it becomes a loss. Don't lose your nerve.

Personally, I had a bit over 100 BTC. When it reached $20 the second time, I sold it because I could use the money and also because I became nervous. While it wasn't the biggest money mistake of my life, it's certainly a whopper in retrospect. Don't be like me ;)
It's a step forward, but treatment is still a long way off:

"Independently of the selected gene therapy strategy, and prior to its potential use in HIV-infected patients, vector technology has to be developed that allows safe and efficient gene transfer followed by reliable transgene expression in target cells"

Gene therapy isn't possible yet because we still can't control where the transgenes get inserted into the human genome. There's the risk of disrupting oncogenes/oncosuppressors, and the probability of getting cancer would be high.

If you have any questions you can email me (I'm co-founder and CEO) directly at noah@percolate.com. Thanks.
Actually, I think what you're really asking for is the ability to write sequential code and have the compiler work out if it could be parallel. It's true that the reducers implementation runs in parallel, but the API is actually agnostic.

Reducers also provide higher level constructs like filter, map, cat (concatenate), take-while, and of course reduce.
Why Bitcoin is Dumb
Bitcoin is the idea is money gets its value from scarcity, which is a misconception since money gets its value from the volume of transactions involving goods and services. The only reason the dollar still has any value is because people still use it to buy energy, weapons, food, etc. If people or large buyers/sellers like China decide to stop using the dollar then the dollar will crash regardless of how scarce it is. That does not mean that some people won’t continue to make a great deal money from the speculation around this dumb idea at the heart of Bitcoin.
Road tolls are quite undesirable. Tolls require some toll collecting apparatus which wastes that portion of the collected funds and may have negative externalities (e.g. increased surveillance, increased air pollution or reduced road capacity due to slowing for toll booths). Moreover, it discourages productive use of the road. If a toll discourages use of a road at any point in time when the road is being used at less than its full capacity then you're "wasting" the road and creating secondary inefficiencies, e.g. fewer people in the office park on one side of the toll road will travel the road to visit a coffee house on the other side which causes the coffee house to lose business, and allows a different coffee house that happens to be in the opposite direction from the office park to raise prices and gouge the workers in the office park.

You can see the obvious analogies with patents on publicly funded research.

This is to be distinguished from congestion pricing which has nothing to do with paying for the road and should only apply at the times when the road would otherwise have insufficient capacity for the traffic volume, with the explicit intent of reducing usage. Note however that congestion pricing can be inefficient for many of the same reasons and is also undesirable unless the alternatives of expanding road capacity or improving mass transit to reduce traffic volume are both impractical.

I'm a big fan of the WNDR3700, bought it on a whim a few years ago, the firmware it comes with sucks, but with *WRT it just works (I've got a V2, have a look at http://wiki.openwrt.org/toh/netgear/wndr3700 for details about versions).

With a powered USB hub and an external disk drive and a webcam, it functions as remote backup via. rsync and monitoring my home when I'm on vacation, when enabled it takes pictures every 2 seconds when there's movement in the frame. The pictures are uploaded offsite immediately.

I'm using OpenWRT and have had very little problems, only issue I've noticed is that the wifi transfer speeds are a bit slower (10-30%) than when using the factory firmware, but I can live with that.

Ha, I don't think this has any value as evidence, but it's kind of funny that in a comment on one of the eventually-postdated blog posts (originally April 2008), Nick explained that the mechanics of the bit gold market would be nonobvious to most people and therefore the idea could use a demonstration project, and asked, "Anybody want to help me code one up?"

He's trying to tie the value of bitcoin to the forced syncing process - "bitcoin represents spent electricity." That's just not right. In reality, bitcoin represents agreement by parties to honor debts in its ledger. Bitcoin's backing is the information system, not the resources that go into it. The value is tied to people's faith in the currency and ledger system.

EDIT - other criticisms:

- He criticizes energy waste, but doesn't compare it to the energy use of existing financial systems.

- He points at the risk of owning wallets without recognizing that this should be a diminishing risk as better software develops.
What gives Bitcoin its value right now is speculators, and what speculators are betting on is widespread adoption. If that never materializes because some other currency has taken its place, bitcoin's value will decline.

And it is only a small subset of the population which ascribe value to monetary decentralization. I count myself among them, but I don't delude myself into thinking that the majority feels the same way.
The awkward thing about ideology is that it doesn't have a built-in feedback loop for measuring performance and adjusting accordingly.
This is a great comment, thanks for sharing it here. There seems to be a demand for a synthetic currency that is not subject to monopoly and manipulation by a political authority. Right or wrong, people do seem to be putting there money where there mouth is. The way this author puts it, its like bit-coin is a combination of gold, farmland, london real-estate, post-war modern art, and Square/stripe all rolled into one. If nothing else, BTC is "on trend" in multiple dimensions. And connecting the dots in an interesting way...
A country is not either capitalist or socialist, its a matter of degrees. Some parts can be capitalist some parts can be socialist. Some countries go more to one end of the spectrum than others.

You can have private ownership of the means of production but that don't automatically give capitalism, capitalism also requires a market economy. You can have private ownership of the mean of production without having capitalism.

If you take the definition of market economy from wikipedia:
(http://en.wikipedia.org/wiki/Market_economy)

>Capitalism generally refers to economic system where the means of production are largely or entirely privately owned and operated for a profit, structured on the process of capital accumulation. In general, investments, distribution, income, and prices are determined by markets.<

What if distribution, income and prices are largely determined by the state but investments are not?
The article mentions physical changes in the mice as a result of the smell (more specific receptors and neurons) which are explained within the current model by epigenetics: expression of "dormant genes" for those physical changes.

So, if those physical changes explain the mouse behavior response, then this has nothing to do with memories[1], and is not an unexpected outcome of the study within the current model.

This article is much too sensationalist, in my opinion.

[1] for reasonable definitions of a memory, of course.
The entire economy is centrally planned.

Edit: Social coordination of the means of production, as opposed to coordination by market forces, is in fact the definition of socialism. Whether it's done by a state or various small groups doesn't matter - both are just variations of socialism. Both are about economic planning.
I wonder when BitCoin will stop being tech news and start being financial news. That will be a watershed.
This is nowhere near the end for this currency, but I'm sure the speculation is going to make for a wild ride the next couple days.
No. If you want to mine x gold today, which will cost you y in resources, you do not predictably have to spend 1.5y or 2y tomorrow to get the same x.
It won't. :)
"-9.4 decibels"

erm, decibel what exactly? Decibel is a ratio between two values. If you don't state the one compared with, you're talking pretty much nonsense.
Well, there's a lot of paperwork and time involved. Most U.S. banks raised their international wire fees to ~$60 at the end of October to comply with more regulations.

The average commute in NYC is 45mins, which is almost 50% higher than the national average. LA always has a below average commute time.

The fact that LA metro has such short commutes - despite being one of the largest and most car dependent big cities in the world - suggests that highways and private cars do, in fact, scale very well.
Where does the Bulgaria thing come from? BTC-E is clearly a russian site.
I'm not defending it. I'm just saying socialism isn't its issue, in fact it cannot be since NK is socialist only in name. Its real ideology is "Juche".

Alleged Sheep Marketplace theft and scam?

Yes. Also, "Waste" is a subjective term. Your computer is solving the problem of trust between humans. That's not a waste to me. It's certainly less wasteful than the energy that goes into hosting servers for popular MMORPGs.
A central authority needs to control money supply. This is crucial in all advanced economies. It has to be capped somehow (currently, it's obviously exploited), but a decentralised currency will never work.
Good example. Toll roads are a sort of FRAND licensing, though-- maybe there are some reasonable guidelines for public patents.
> It is much less debatable, I think, that Leninism is an honest (in the sense of not being intentionally wrong or deceptive) continuation of the original Marxist sociology and economy

Whether it is "honest" or not is largely beside the point, which is that it is a deliberate attempt to short-circuit what in Marx's theory was an essential step on the road from feudalism through developed capitalism and then socialism and finally to communism, and that a such a short-circuiting effort cannot be an empirical test -- whether it succeeds or fails -- of Marx's theory (well, except insofar as its success would refute at least one element of Marx's theory.)
Which isn't the definition of socialism.

It is possible to write an essay by making a thesis and citing diverse examples to support it, but this is not the only way (or best way) to write an essay worth reading. I find essays much more valuable when they provide a clear thesis, cite extensive high-powered evidence in support of that thesis, and directly address potential weaknesses in their arguments, possibly with some explanatory text to provide logical or causal inferences related to the evidence. I don't typically find that diverse examples constitute high-powered evidence, which is why I don't consider essays that follow the Salon style to be particularly compelling.

If you are willing to cherry-pick anecdotes and examples, one can make a case for almost anything, but if you are anchored to actual facts (ideally ones which are statistically valid) you provide a much closer mapping between your opinion and reality.

Perhaps we differ on what sort of texts count as essays, but I would note that many people on this site find Paul Graham's essays to be compelling, and in general his essays do not comprise a collection of disparate examples surprisingly linked through a common thread.

The concern is not new. It's been around for centuries.
As the rest of the essay indicates, the problem of trust is hardly "solved." I'll grant that it's an attempt to solve the problem, but the end result is Ponzi-scheme-level risk of losing everything for a given holder of value in Bitcoin.
Different strokes for different folks. I think its decentralized nature is its least valuable aspect. If the only thing it accomplished were smoother and cheaper internet, small business, and interpersonal commerce, it would be incredibly valuable. The novelty of it (which I think has a lot to do with its decentralization) is currently causing too much volatility to make it useful for actually buying and selling things. A more boring government-backed (or -regulated) variant would be more useful and extremely valuable.
SEEKING WORK - London/Kent (Remote preferred) Python Freelancer, Experienced in mentoring teams and getting to Continuous Delivery.

I am a rare beast, Ex-CTO who is still full-stack developer, I have seen most business and software problems up close and personal but I still love finding new ways to tackle them - a developer who recognises most business problems are people problems first and a manager who believes everyone must be able to code.

I can build a team around your existing vision, create a business around your insight or simply help you fix what's broken.

I spent all my savings back in 2011 on bitcoins. I get what you mean. Good luck.
I've got pfSense[1] running on a passively cooled embedded board[2]. I then use whatever wireless APs I want in bridge mode.

I like this because x86 will always be compatible with anything I might run in the future, and changing out wireless hardware from 2.4 N to dual-band N to ac has been trivial and required no thought to compatibility.

Except there are no debts, since there are no debtors. The ledger is a registry of ownership, not debts.
I didn't expect to receive a device primarily meant to serve me ads, sorry if this is a naive expectation.

The product page says the ads only appear on the lock screen. They do not (or should not) appear when actively using the device.

Is this not true?

I'm genuinely curious because it would suck big time if you are shown ads outside of the limitations the product page describes.
Being a good store of value is in fact a detriment to being a good medium of exchange. A currency should not be a good store of value, it should be a predictable store of value that inflates very slowly so as to discourage hoarding and encourage spending. PPC looks like a better currency than BTC for this very reason.

$800k Bitcoin Transfer
If this theory is true, it shows that BTC lacks book depth and the current price is just speculation on the edges, not a true price for the entire stock of BTC. (That is, if a large portion of BTC users wanted to get out of BTC, they couldn't realize the nominal market price.)
Not sure what is your source, but BTC-E says the following:
