> That's lovely but your post isn't really contributing.

To the extent that is true, I kind of thought I addressed that with the first word of the post.

> bmelton was pointing out an actual misuse

And I was pointing out an actual error in bmelton's description of the actual misuse (which -- see below -- is repeated in your description.)

> "Decimate" can mean either large percentage or the traditional 10% drop

No, it can't. It can mean reducing by a large percentage, or it can be reference to actually killing 10% of a group of people as a form of collective punishment. It does not mean reduce by 10% in any general sense any more than it means reduce to 10% in any general sense (though the latter is more likely to be within its general meaning than the former.)

> Your post moves into pointless word argument territory.

Well, I would say that tptacek's point was entirely clear despite the misuse, and that both bmelton and my responses were provided with accurate warnings by their submitters as being pedantic ("overly concerned with formal rules and trivial points of learning.")

I'm working on a home page redesign right now, so yeah I'll have that done fairly shortly... probably a few weeks. The new version is a bit more "pro" or "enterprisey" looking and tries to clarify things a bit while continuing to keep it simple.

Clarifying the message has been tough overall. In some ways it's so simple it's hard to convey. "Connect ALL THE THINGS!!#$!#$!#4!11" ?
Hmm, this has been true for some projects I worked on. When there is a stable dev lead for many many years. He needs to teach others his approach. Then it's perfect. People tend to keep things that work well. Just don't hire those who want changes:)
Yeah, it's worse than it sounds though. If you write to 2/3 nodes, and the third gets elected, you can roll back majority confirmed writes. I think it did even worse things when near capacity, but those are harder to pin down.

The Sony hack will probably be used as an excuse, whether that's the main reason or not. That's how the US gov operates now. They take advantage of certain situations to pass or do stuff that normally would have no chance of passing, even if those situations are barely related to what they're trying to pass.

Example: The Patriot Act written many years before 9/11 by law enforcement agencies to help them in the War on Drugs, and then shamelessly used the 9/11 excuse to pass it. If the Patriot Act was "just about terrorists", then it should've referred only to terrorists. But it didn't. And now 99 percent of NSLs are used in drug cases.

Cassandra avoids some of the really visible issues by being AP instead of CP. Hbase hits them, but dodges a bit by only having row level consistency. They are solving very different problems.

The lack of vector clocks in Cassandra can lead to some very non-intuitive (possible wrong) behavior - check out their counter implementation for some rage on that. It's pretty well made though, and I think C*, Hbase and Postgres all have great uses (along with Redis, and a lot of others)

Mongo tends to get things subtly wrong in ways that corrupt data, or that don't scale, and it gives up both A and C.

> Do Google's lawyers have some sort of Google Lawsuit search engine to find the relevant cases?

I wouldn't be at all surprised if Google is dogfooding some kind of as-yet-internal-only tool of this kind, but most lawyers (and law students) have very powerful legal search tools (which are not at all cheap, because they involve not just algorithmic search -- though they include that -- but also quite a lot of expert human curation) for this purpose.
Well be specific. Some have been caught due to using outdated Tor software. Others, like the recent Silk Road bust, because they used "hidden services" incorrectly, and the hidden services were never actually advertised by Tor as being perfectly safe.

But the latter one has nothing to do with users, but with "website" operators inside the Tor network.

On 淘宝 (taobao.com, the largest Ecommerce platform in China) users can see both sales volume (how many of that item did that seller sell in the last month) and inventory (how many items does that seller claim to have in stock).

I'm sure that some of the inventory numbers are inaccurate (i.e. the small retailer doesn't have 100k units of something in her warehouse) but I know that some retailers (particularly for clothing) do provide accurate inventory numbers (down to size/colour level) so that, when I am adding to my basket or checking out, I can see if I need to hurry.

I think it's both a problem companies like Apple can do a lot more to address and likely to be significantly better than the alternatives most of the employees have available.

People aren't joining Foxconn from jobs where they've got 40 hours a week and vacation time. They're often joining from rural areas with subsistence farming, poverty, shittier jobs, etc. International attention on Apple and Foxconn likely prevent at least some abuses that are rampant elsewhere in China.

All that said, there's no reason we in places like the US can't pay $20 more for an iPhone.

Project based learning. Students propose projects as a team, relevant faculty mentor them. For example, to learn web dev a student might propose building a SaaS app. He would ask relevant faculty to mentor him and peers to work on it with him (devs, admins, designers, ). The team would elect a leader and have regular checkins with their mentors. The only job the mentors have is to help the team succeed. If they want to do their own research or work, then they should encourage a student to find a team and propose it as a project.

Each student could do 8 projects over 4 years. If one takes off, they're in a position to take a break and try to make it as a startup. That'd be encouraged by their mentors, and ownership / IP would be structured to benefit the students with a slight stake for the mentors and university (< 5%).

This would provide many real world skills (what you're doing in the project, leadership, working with others, etc). It'd also help the students build a track record of independence and success.

I'd hazard a guess that hok and krak have some component of instinctual/physical nature to them. I personally think that certain sounds are related to physical experiences or expressions of emotions. Obvious ones are surprise of "Oh!" with an open mouth.

"Hmmm" whilst thinking or concentrating, frowning and closing your mouth.

I'm currently watching my son learn to speak and his verbalizing seems pretty closely tied to his emotions at the moment.

"Oishii" means delicious in Japanese and it seems something that makes sense to say whilst you are smiling at enjoying your food. The long "ii" vowel to rhyme with the "e" of "she" in English.
This meme that Zen is a philosophy is incredibly unfair / misguided. It's a religion. It's a branch of Mahayana Buddhism, it's practised as a religion, in some regions it still has the aspects of Guru and Deity worship that have been inherited from the larger schools. The full name of the religion is Zen Buddhism.

As someone who has been involved with the religion and with Japanese friends who are also a part of it, it's incredibly belittling when this idea gets spread around. It's only in the West that all of the cultural and religious background has been stripped out and turned into a marketing device.

I often joke that if Buddhism had more extremist members we'd have a lot more holy wars than anyone else. Dressed up Buddhas, Zen stapled onto every two bit startup and cheap product, blogs about consumerist driven minimalism selling themselves as "Zen". It really is ridiculous. What is being done here is just as offensive to eastern cultures as if an East Asian startup branded itself using Christian or Islamic imagery or terms, citing that it's all just "philosophy".

Anyone stealing these terms and imagery really should read some of the critiques of Western misappropriation of Eastern "Spirituality" like "The Scientific Buddha" or "Selling Spirituality". Or even just take five minutes to consider the countries and contexts they might want to operate in as they grow.

The best project I've ever worked on was like this. I don't think it's an anti-pattern; if anything I'd see it as a positive sign, as it indicates a project that's under continued development and willing to investigate new technology.

Just as it's vital to accept that business requirements will change during a project, and structure your methodology to accommodate this, the same is true of technical considerations. And the same solution applies, viz. Agile: break up any "redesign" into small steps that can deliver concrete benefits inside a two-week period. Don't treat the "transitional architecture" as a temporary thing that doesn't need to be good, doesn't need documenting etc.; like with a big database migration, you make sure that at every stage it's something that you can develop under, and you know what you'd do if you had to abandon the plan at any stage.

If you try to keep a codebase on 2003 tech forever, you're storing up trouble for later; devs will become harder to find and more expensive to hire, and eventually you'll be forced into a Big Rewrite, and we know how those turn out. Like with deployment, better to embrace Continuous Re-Architecting. If it hurts, you're not doing it often enough.

Again how many stations exist? I'm not arguing the concept, I am arguing the feasibility. What is the cost for fueling at these stations? Solar panels generate electricity yet we don't use them to power industrial operations because solar expensive! Just like H2 from electrolysis won't be able to compete with industrial H2 production from coal. Also, what you're suggesting is using predominantly coal to generate electricity from a traditional plant (~40% eff), then transmitting the electricity to a station (90%), then creating H2(60%). Compare that to coal steam reformation (75%) and transportation (80%, being conservative), the latter is far more efficient and cheaper.

And what infrastructure do you need? A gas truck with a pressurized tank on it. The cost of hydrocarbon based h2 will displace electrolysis in large scale production.

And your last point about distributed load efficiency gains, electric cars are already able to balance load and feed into a grid. It's always going to come down to cost, I'm going to buy the cheapest h2 around and it's going to come from steam reformed coal.

There are some other ways an rf can be made to handle missing values including splitting the values onto a third branch at each node (which can be useful if the fact the value is missing may be informative), just leaving the missing values out at each split and applying a bias correction (as was common with pre rf decision trees), or doing a local imputation within the in branch cases at each node.
Dang, I was going to try to refute you by saying no license meant no restrictions, but nope! Creators of software (and any written work apparently [1]) are automatically granted copyright for their work (this makes sense) so without a license, copying it would be a violation of copyright. That's wild, but seems reasonable.

Posting it to Github isn't implicit permission, but it would probably be a factor if the author did try to sue people for using his or her copyrighted work without license/permission.

The United States Government will fail because even if they were to significantly disrupt the Tor network we'll pull out the Zero Knowledge Proofs on them. We have the crypto and technology to build a super resilient Tor replacement that they cannot do a single thing about. Tor is antiquated and I personally hope they take it out because it's replacement will be 100x better.
So why couldn't signed lists of relays just, say, float around on a DHT, with a cache-and-forward model like Freenet, but where newer documents (provided they're signed with the same key) will overwrite older documents in the same cache slot?

Actually, to put it another way, Freenet is itself the optimal bootstrapping mechanism for Tor. Maybe the two projects should merge, such that Tor would effectively be an optimization over the specific case of two peers generating and searching for one-another's signed Freenet documents (this effectively being an IP tunnel already).
I'm not sure if the above comment is downvoted because of the Patriot Act claim, but that claim happens to be correct. I wrote about this for CNET here:

http://www.cnet.com/news/how-bin-laden-and-911-attacks-shape...
"Long before 9/11, the U.S. Department of Justice drafted the so-called Enhancement of Privacy and Public Safety in Cyberspace Act (PDF), which goes by the awkward and not very memorable acronym of EPPSCA. In July 2000, the Clinton administration forwarded EPPSCA to Congress, where it was introduced by Sen. Patrick Leahy (D-Vt.) and met with a generally chilly response... EPPSCA was designed to give police more authority to conduct Internet surveillance, not thwart terrorists armed with box cutters... within hours of the 9/11 attacks, the Justice Department had dusted off EPPSCA as a way to respond to bin Laden. On September 13, 2001, two days after the worst terrorist attack in U.S. history, the U.S. Senate approved the "Combating Terrorism Act of 2001," which includes portions copied directly from EPPSCA."

As for the rest of the above comment, this is likely to be a fluid situation and I'm reserving judgment until we know more. It is possible that the good folks at Tor are wrong (I'd like them to be!) and no seizure happens. Government authorities sometimes bluff.
I'm not sure to understand HN's ranking system. This is top page and is an article extrapolating sexism in a particular field from being trolled on reddit, which seems to me quite common. (Also, the article had 5 points and one comment as of this posting)

Staples says security breach may have affected 1.6M credit cards
The most difficult project I have solved (just finishing up the implementation) is developing a monitoring solution for a bunch of legacy telephone PBX's.

Essentially, the bureaucratic overhead for getting a bunch of companies to open their firewalls to us was unfeasible. Long story short, I ended up hijacking the SSL/VPN generated by a running JVM to forward a bunch of SNMP/OSSI-polling traffic to our api.

At the end, after implementing the above, I found out about a service port for outgoing only traffic offered to business partners. That was much easier to use, only requiring nginx to split off a certain sub-path of SSL traffic + business partner status.

I am still proud of the original hack, although brittle and ugly it was very exciting to get working.
