"It is widely known that bitcoin is resilient to any attempt to double-spend unless there is a coordinated attack by greater than 50% of the total hashing power"

First of all, it is hard to even analyze "total hashing power." There are far too many slippery details for any formal analysis -- you need to know how the hash function is actually implemented, what sort of hardware, etc.

That being said, how do you know there are no other double spending attacks? Where is the proof of that?

"double-spend is the _only_ attack at the distributed algorithm level."

Prove it.

"then there is the crypto level"

There is no such separation. Bitcoin is not a signature system, nor is it a hash function. The fact that ECDSA and SHA256 are used in Bitcoin does not imply that Bitcoin is secure. All that you can really say is that Bitcoin does not meet its security goals (whatever those are) if ECDSA or SHA256 are not secure.

I'm with you as far as suspects. Suspects should have their rights protected. Convicted felons, however, we already deny a number of constitutional rights de-facto. E.g., right to bear arms and freedom of travel.
Friends and family I've lost to:

- vehicle accidents: 4

- terrorism: 0

But that's not really the issue.

If you believe that this was a matter of community cohesion -- of a society being strengthened by the annealing blows of terrorists incidents -- then I'd concede your point. But, judging from earlier experience, something else is happening. A climate of fear is being generated that is vastly disproportionate to the objective risks.

Remember: the people at the marathon were not the target. That was just a means to an end. The real target was the American psyche. Did they succeed?

Or, since you started by talking about deterrence, let's look at it through the eyes of potential future terrorists. What are they thinking right now? Are they thinking, "Oh no. Those guys got caught. I guess I'd better not try anything like that." Or are they thinking, "OMG they shut down the whole city. We got the attention of the whole damn WORLD! AWESOME!"
What we're seeing now is the conflict between Consumer vs. Cosmopolitan America

Cosmopolitan America, if it exists as a mass paradigm, is at this point mostly aspirational. Our entire culture and economy revolve around consumption. Most jobs are in service, not production. It is difficult to be a citizen of the world when the world is so disunified -- see attempts to do anything of use to combat global warming.

Meanwhile, capital is doing its very best to coopt any nascent consciousness of Americans as producers rather than consumers. You can see how quickly, for instance, hipster culture, which started out as anti-consumer (thrift stores, reclaimed industrial spaces, living in the cracks of society producing art instead of having normal jobs) was commodified and turned into fashion, and people who were drawn to hipsterdom were channeled into more appropriate avenues for buying.

I don't think refusing the accused a voice would really help the investigation of most cases, nor the course of justice. But the path the US (and allies, such as Great Britain) have started down is a very dark one.
Depends on what your needs are. Do you want the coloring and grouping? Do you want Perl regular expressions? Do you want to only search source code? Do you want to be able to specify specific filetypes, like "ack foo --perl" or "ack foo --nohtml"?

git grep is neither superset nor subset of ack. Each tool has its place.

bitcoin does not work that way. Inflation decreases at a set rate.
"Cohesion" is a nice way to sum up what I was attempting to get to.

As for potential terrorists, I guess I still struggle with what their goals are. I think a lot of people are way off the mark. How many terrorists celebrate that Americans take off their shoes at the airport? Many people seem to think terrorist ballads must be written about American Shoe Removal, but I personally don't think they give a crap.

As for simply giving the event attention, I don't think there's any way around that. People hate it when the government tries to hide things. Now, villain-worshipping the two men (comparing how their "score" compares to other attacks, etc) is certainly a terrible idea, but I am hoping we won't go there this time.
Actually, I'm surprised they get away with keeping that data for so short a period of time. For some reason, I thought I read somewhere that US law mandated service providers to keep that sort of data significantly longer. I can't find the reference now... so I must have been mistaken.

I guess I'm more surprised that it's only kept for 2 years, than I am that the data is kept.

Thoughts on the Boston Lockdown from the edge
Still, terrorism is not a crime of opportunity. You need a very strong motivation to do it, and even though you may not necessarily seek death and may make escape plans, you certainly have to accept the possibility that you will get caught.

Also, if these guys were seriously trying to get on a plane, they would have been caught even without the lockdown.
You should search for 'somebody should' in addition to 'someone should'.

Excel is not ruining the world. If someone is stupid enough to create a sophisticated model that runs billions or even trillions of dollars in Excel then they will get what they deserve. Use a database, use Fortran, don't use Excel for that.
This is pretty neat, I like it.

On this topic, is there an app or site where I can just view inspirational pictures from sources like cgsociety.org CG Choice Gallery, and perhaps others (500px, Deviantart). A place where seeing the next photo is just a swipe or 'j' press away. Mostly I'd like cgsociety because they have a very clumsy way to view photos one after another (you have to open each one in a new tab, etc.).
Using the same example, if it's a lawyer that sends a bogus takedown notice (at least in clear-cut cases), you could always notify the relevant bar association to look into the idea that this person might be unfit to practice law in that area (either too stupid of the law to be allowed to practice, or abusing it and needs to be stopped).
They could hire people to operate the pickaxes, like how BFL would have to pay for electricity to power their mining hardware.
When modeling something where mistakes are expensive in Excel, a reasonable person checks their work. I've made Excel spreadsheets that are responsible for millions of dollars in inventory purchases. You better believe I check the shit out of those. I'm paranoid about making mistakes because a small number multiplied by a million is usually a dollar amount of consequence.

In my opinion, people who don't check their work, just don't check their work. Whether they're using Excel or a "real programming language" doesn't matter. You can't blame Excel because people are reckless.

I completely agree with moxie marlinspike but...

This article is two years old, and the effort behind the convergence project (http://convergence.io) seems to have moved on to tack (http://tack.io)
You example is so extreme as to be redundant. You are essentially arguing for abuse of human beings, in a wild exaggerated "24" type scenario, that doesn't really exist.

If my rights depend on abusing other human beings, I don't want them. They are worthless, because one day it could be me, or you.

Are you really prepared to give up your rights if law enforcements believes you threaten the rights of others? Would you accept it if you could not challenge that? Really? I bet you just assume it only happens to other people.

Lastly, this notion of every one getting their human rights simultaneously is absurd. As I said, they are only required when things go wrong or are difficult for a public to be reasonable and fair. I don't need my right to not be blown up while a police officer is observing Miranda rights, for example. This suspect's right to a free and fair trial has no baring on my right to not be harassed by government, or be blown up. Its a totally false premise, which makes no sense.
The more people get excited about faster ways to hoard bitcoins and eventually make a nice profit (presumably in USD in the end) the dramatically more cynical I become about its future. When the bitcoin discussion was mainly around its use as a currency for things like silkroad, VPNs etc I actually thought it seemed to have a promising future. I really hope I'm wrong, but I have a feeling in 2023 the bitcoin discussion will be relegated to nostalgic jokes about how crazy we used to be.
> As for potential terrorists, I guess I still struggle with what their goals are. I think a lot of people are way off the mark.

Hmm. You're right

The grievances that drive terrorism are well understood. But beyond that I'm making confident assumptions that, on examination, I can't back up with any solid evidence or experience. I guess this is a case of "more research is needed".

> As for simply giving the event attention, I don't think there's any way around that.

You're right, of course, but I'll continue to rant about it.

If traffic accidents received anything like the attention that terrorism did -- if videos of fatal car crashes were replayed ad nauseum on the nightly news -- maybe some of those 4 people I mentioned above might still be alive today.

Good for them on following through, I'm sure it will bring repeat business. Maybe 6-7+ years ago I attempted to make multiple purchases through dell.com over several months. All 3 were killed because the website listed the wrong price. I remember once I bought something like a USB drive for $47.99 and the real price was suppose to be $49.99. None of the purchases were near 20% off much less 90% in this case. I've still never ordered from Dell and never will.
the article should mention that mw2 was the first cod without dedicated servers and officially killed cod as a competitive game. they could have put in the game worse things than dogs / choppers / nuclear strikes / martyrdom^3, a simple mod would have removed all that crap, but without a dedicated server you can't really have competitive gaming.

FEAR too might have deserved a mention.
It would be helpful if some of the Silicon Valley venture capital / startup capital was as enthusiastic in investing in non-Silicon Valley companies. I've heard on more than one occasion that the company was great, but the only reason they are not investing is because it is not located in Silicon Valley.

The truth is that the World Would be Better if a) VC in the Other 50 Silicon Valleys had the Same Appetite for Risk Taking as is present in Silicon Valley or b) If Silicon Valley VCs were much more open to investing in the Other 50 Silicon Valleys.

Yes, it is true that at the Angel level, there's a much broader access to capital now more than ever in a broader range of geographies, but once you start to get into Series A rounds and higher, the bottleneck ("squeeze") becomes evident, and this is where Silicon Valley has a sizable advantage over other regions.

There's no lack of entrepreneurial talent, willpower, or ideas in the Other 50 Silicon Valleys. Rather, the lack of investors willing to invest in these risky endeavors to the point where they can reach the liquidity necessary to self-perpetuate their local entrepreneurial ecosystem. Small exits are necessary, but not sufficient to keep a startup ecosystem going on its own. You need large, $1B+ exits and IPOs on a fairly regular basis to do so... and that requires the financial power equivalent to what's now mainly in Silicon Valley, and perhaps one or two other locations, tops. But not in the other 47+.
The evolution was CPU -> GPU -> FPGA -> ASIC. Now that we're at the ASIC stage growth is going to slow considerably. There's no longer order of magnitude gains to be made.
All rights in law are a balancing act. For example, when people were lobbying to "Grandparents' Rights," codifying such rights into law would have given power in custody-type situations to the grandparents, but at the cost of taking some level of rights away from the parents.

My 'right' to murder someone is taken away by the law because it is deemed that the right of the other person to stay alive is more important.

In this case, the only right that is being taken away is the right to be informed (or reminded) of your rights prior to interrogation. He still retains his right to remain silent, he just isn't specifically told about it by police. The purpose being to allow a line of questioning that would help to eliminate the risk to the general public (in this case accomplices, hidden bombs, ties to terrorist organizations, etc). If they use this as an excuse to ask him questions that clearly aren't going to help resolve the "risk to the general public," I'm sure his defense attorney will have a field day with it.
The problem is that most parts of the world, while they want to reap the benefit of a Silicon Valley they don't want to put in place the ecosystem necessary for it.

It's not a coincidence that Silicon Valley exists on the doorstep of the most diverse community in the US - not just ethnically but in all areas of lifestyle diversity. Many places are not prepared to embrace that.

Embrace of failure is incompatible with deep seted cultural values in many parts of the world.

Tax regimes... Legal structures favoring equity sharing... At will employment...

Most of the places that want to recreate Silicon Valley always seen to add a "But Our Way". Problem is "our way" means keeping in place many of the sources of the failure which those places have had to date in having already created their own Silicon Valley. (Typo apologies via iPhone)

Are people using Azure Mobile Services happy with it? I watched the first NSScreencast on it, and it just seemed to introduce so much complexity. If I wanted to manually configure SQL tables, I'd make my own backend. Parse on the other hand was extremely well documented and required 0 server or database knowledge.

Edit: Personally I don't find Azure marketing all that interesting, but they have been doing a great outreach effort. In addition to DF, they've two sponsored NSScreencasts and the latest iOS dev weekly newsletter.

It's entirely to the authorities whether to Mirandize the suspect or not. Perhaps they think they already have so much evidence that they don't need any statements from the interrogation to convict. In that case, they're just looking for information.

Remember, the authorities are perfectly free to interrogate you as much as they like without reading you any warnings at all. It's only at trial that the warnings become relevant. If your case isn't going to trial, it's not relevant.
8500$/week. Just with his blog. It's just crazy. I don't think there is another blog out there that earns even half of what Gruber is here. I just can't understand that.
How is that at odds with anything I've written above?
When someone spouts big talk like "start doing things right. Since you don't know how, you have to hire someone like me and give that person lots of autonomy, but it can be done" and all they're known for (please correct me if I'm wrong here) is writing a lot of text on HN, I don't think a little snark is out of line.

I get that railing against unsympathetic targets like big corporations makes for entertaining reading, but I don't think that actually qualifies anyone for the job he was describing.
I agree. And what's worse is often it is hard to find a way to contact the author to ask about the license, or they flat out ignore you.
True. But a lot also depends on the context. When you are dealing with some binary, unless it is antique, most likely you are doing something nefarious. Like obliterating somebodies license check. And while there is certainly a feeling of some elation, when you are finally succeeding, it can't compare with the joy you feel, when some electronic component is coming alive after you've finally fixed it.

> There are some real ports of Linux for "limited" architectures, like uClinux (supporting few 32-bit micros, including some MMU-less ones) and ELKS (for 16-bit x86 CPUs).

But is it actually Linux, or something that was based on Linux but is now so divergent as to be its own kind of thing?

"Oh, it's Linux. It doesn't have most of the APIs, including the ones 99+% of the application software depends on, most of the code is gone, what's left has been greatly re-written, and it will never contribute code back into the mainline kernel."
