So having a miner in your pocket is certainly one way to execute a double spend. That's a Finney attack.[0]

The other and less costly way is all about node connectivity.[1] If you are going to execute a double spend all you 'need' to do is broadcast two txs spending the same output at the same time--one going to the merchant the other spending it back to yourself--and cross your fingers and hope the double spend gets put in a block. Now, you can increase the probability (e.g. shielding the merchant's node from your double spend) of success but it's not a sure bet. And the higher the node connectivity of the network (i.e. how many nodes are each node connected to) the harder this attack becomes.

There has been some work in this area, especially in pursuit of the efficacy of double spend attacks in light of some minor changes to the protocol which (I think) were rolled into core with the most release 0.9.0.[2] It's about .09% probability of success.

IDE's aren't as big of a deal in Python as they would be in C#.

A lot of people just pick a nice text editor to do their work in. I like to use xcode on the mac, but I use Python's built in debugger from the command line for debugging. I find it easier than fooling with an IDE.

By "indentation" I meant using that for conditional blocks, instead of the C-style bracketing that I'm used to.

I found that list of IDEs, but basically what I'm asking is what are people's favorites from that list?

Solving the software problem
Would I need to know how to do a lot of administration tasks? For example, when getting an ec2 instance, I pretty much have to build the whole server myself. That means I need to know how to secure it properly from hacking, as well as set up clusters, all the software (apache, nginx, haproxy, etc) with the right configuration, etc.

Additionally, when something breaks in the middle of the night, I'm going to need to know how to troubleshoot it. What do you think?

Ask HN: Hiring an Employee in a Low Income Sole Proprietorship
Maybe the community can help educate me on this question I've had for a while.

Aside from my day job, I've been running a small software business (selling add-ons for a CMS) that maybe brings in about $200-$300 a month in income, which isn't much.

However, I'd like to grow the business and there's a past student of mine who's been helping me out for about 6 weeks now as a volunteer at my day job and now I've had him also start helping me with some bug fixes and new feature additions for the software I sell.

I'd like to hire him properly, and I'm sure I could use something like Zen Payroll to help out with the paperwork and other taxes that would be incurred to do so (Zen Payroll is relatively inexpensive, but I'm not sure how much the California/Federal taxes/fees might be), but I've never hired anyone before so it's kind of a scare thing (after the first hire it should be a lot easier :-). Would hiring that first person using Zen Payroll as easy as signing up and adding him in?

The conundrum I have though is, how can I hire someone, when the business itself isn't even making enough to provide a decent wage? With our current income, I'd really only be able to afford to pay him for a few hours a month (if I was solely relying on the business income).

Should I start small and just pay him out of what I can afford right now, or should I bring in more of my own money and make it easier to give him at least a few hundred dollars in wages each month?

Thanks for the help!
I happened to be visiting Turkey in 2010 when this idiot was seeking re-election. I kid you not, I felt like I was in a movie. There were propaganda posters literally on every single block in Istanbul with his ugly face on it. Every few minutes, a truck would drive by with people blaring through megaphones about how great this idiot was.

I bet tons of Turks voted for him simply due to the overwhelming media propaganda blitz that was his re-election campaign.

> a) try your new code by saving in your editor, and hitting reload in your web browser.

The only language for which that works is client-side Javascript. For PHP, you forgot the part in which you have to install and run a web server, then point your browser to localhost. Plus, to get anything useful done, you'll also need some sort of database to go along with it. I remember the first time I did that and it was pretty intimidating.

> c) it's not super high overhead at runtime ... it's not too hard to get your page out with about 10 ms of overhead beyond data fetching

To me much more interesting is the total time it took for the client to receive the response, possibly when multiple concurrent requests are happening. The comparison here should be versus a static page served by Nginx of course.

The best throughput possible that I got for an otherwise complex business logic happened on the JVM. I basically rewrote a web-service built on top of Django/Python, with a redesign with emphasis towards in-memory caching, parallelism and async I/O and the result was a server that was able to process more than 10,000 requests per second with an average of about 5ms per request (actually in production the instances ended up processing about 2000 reqs/sec of real traffic, since c1.medium EC2 instances don't have enough CPU power).

Of course, people that just need to slap something together, don't need this level of throughput. If a request takes 400ms for a dumb web form on a low traffic website, that's of no consequence to most people. The problem happens of course when such a piece of software evolves to something much bigger, like Wordpress. I'm always amazed at the gimmicks that people do just to keep their Wordpress powered blog alive.

It can give people the confidence to do things they should absolutely avoid doing and KNOW they should avoid doing. Things like a new and more effective wing deicer sometimes have a similar effect.

Sorry, but when you use the example of a repressive, communist regime that gives its people hardly any freedoms at all as an example of a better way of running a governmentyou kind of lose credibility.

Not to mention the fact that China seems the be having a massive problem with official corruption. In fact, China's official corruption problem is arguably worse than America's. At least our politicians are bought with campaign dollars. It appears that Chinese politicians and bureaucrats are bought with direct payments.
The Physics of Customer Acquisition
Does this company do research or implementation of existing research?
I love metered billing. The problem with it is that the video streamers will discover how much more bandwidth than everyone else they're using, and AT&T and Comcast's all-you-can-eat video services that use the same wire will look a lot more attractive to them.

Ultimately, that may be a threat to network neutrality as the prices are raised on the metered internet in order to shift bandwidth to those siloed TV services, and the public won't care because they're not streaming video over the open internet anymore.
Love this so much.
Thanks - yeah I will certainly need to shift my thinking away from c#-style (read: Visual Studio) development.

As for pdb, I guess I've been spoiled by Visual Studio's debugging - hover to see values, step through source code, etc.

> Computers based on neuromorphic design are the best bet for intelligent Machines.

I wouldn't go that far. We don't understand enough about the nature of intelligence and the way brain works; right now saying that "the best bet for AI is for computer to look like a brain" is like saying "the best bet for heavier-than-air flight is for a machine to flap wings like birds", which was a stupid idea for the reasons we now understand well.
We disagree about how well redistribution can and has worked at scale. My ultra-compressed (lossy) take is "pretty inefficient, but somewhat effective improving the lives of the less-wealthy".

One of the most dramatic and promising examples of redistribution, GiveDirectly, is actually doing some followup research on the effectiveness of their redistribution, and it looks pretty good so far: (pdf warning) http://web.mit.edu/joha/www/publications/haushofer_shapiro_u...

That's an extreme example - a relatively-small scale transfer from wealthy donors to a much poorer country - but it speaks well to the principle.
The Forrester note† that the article links to is a little more balanced that the NYT article. If you don't have time to read the whole thing, here are some good quotes:

It's naive and dangerous to think that the NSA's actions are unique. Nearly every developed nation on the planet has a similar intelligence arm which isn't as forthcoming about its procedures for requesting and gaining access to service provider (and ultimately corporate) data. As stated in the ITIF report, German intelligence has the G10 act which let's them monitor telecommunications traffic without a court order.

The fact of the matter is that the IT services market is a part of our portfolios because it provides capabilities we value either against IT or business metrics. And it's highly likely these values are worth more to you than the potential risk you think your company faces due to government surveillance. And if your company is a prime target for government surveillance, you are probably being watched from within your own firewalls right now.

... you can take actions yourself to protect your data from prying eyes when using these services. A quick tip: bring your own encryption. If you hold the keys the governments can't get to your data by going through your service provider.

I'd disagree if you say PHP powers about 70% of the web. Web servers (and all other kinds of servers) are not written in PHP neither are protocols that drive the web. Operating systems are not written in it either. These (and many more) are what power the web, not web applications. Your definition of what "powers the web" is remarkablly wrong.

We have been running solr in production for 6 years or so. But I have with interest been following the ES development blog, since I think they have a nice api/features.

The momentum/community behind elasticsearch seems to be building rapidly(to get an idea, just follow the "This week in Elasticsearch" posts on http://www.elasticsearch.org/blog).

Having said that, solr have been rock solid for us so we have no real pressing need to switch. Also we dont really have the problem(massive scaling) that elasticsearch seems to be built to handle, we just have 15 mio pageviews or so pr month. Our setup is 1 solr master, and 5 solr slaves(one on each of our 5 webservers). And do nightly dataimports from our SQL server database. That last part is indeed where I think solr currently have a nice advantage over elasticsearch. The solr dataimporthandler is really nice if your primary datastore is a SQL server, and allows you to do all sorts of nifty javascript and other transforms on the data in-flight as you stream it from your SQL server. For elastichsearch there is a jdbc-river thingy that sorta lets you do the same, but it isnt as polished or usable as the solr dataimporthandler(IMO). And if you want to install it you have to do it via a plugin link that points to a bit.ly address.. which makes me feel uneasy.

I also like that solr comes with an admin GUI out of the box. There exist some ES equivalent plugins(mobz/elasticsearch-head), but like with the jdbc river its a thirdparty plugin and I guess you have to trust that it doesnt screw with your server. With solr all you need comes with the distribution, so you dont need to spend mental energy on wether or not you can trust this or that plugin to run on your server.

Also the .NET client for ES seems very polished and more sexy than the solr equivalent.

Anyway my non-scientific gut feeling is that with the current momentum behind ES, it will over time be a better choice than solr. But unless you really need to scale massively, plain old solr is available and works just fine. And seems to me to be somewhat easier to get running than ES(but then again I'm probably biased after having run solr a long time).
It seems to me that the big flaw in this is that if something isn't reported (deaths, DUIs, truancy, etc), then the Mayor doesn't see it.

And while some might find the concentration of information overwhelming,
Walsh finds it helpful.

“You learn to focus on certain things,” he said.

So he's focusing on things that are reported. What about the things that aren't reported? You can't just focus on things that are reported, you also have to see the missing pieces and work with those.

Not that this isn't cool... I just wonder what the repercussions of his "focus" can be...

Call it what it is, an expert system, market research, a database of decisions/observations. Real "artificial intelligence" only exists in science fiction, in the minds of children playing with toys. Your computer (doll) won't ever love you back or have any awareness or understanding no matter how bad you want it to. It's a cool sounding buzzword for marketing, but if there's any intelligence here it's coming from a few developers hiding behind their tricky algorithms.

A computer will never have intelligence, no matter how many factors and randomizations you code in to give the illusion of intelligence. Calling a collection of observations "intelligence" is an insult and severe underestimation of what intelligence is. If you believe artificial intelligence is possible, you're missing out on what life has to offer--or you would never think a box of switches could come alive.

There's no hint of evidence you = your brain. It's safe to say the brain processes information literally. But we have no idea where intelligence originates. Sadly, some people never get beyond a literal interpretation of things.

Disbarment? No. Sanctions? maybe. It depends on how relevant the misunderstanding was to the actual prosecution of the case. While the prosecutor was very technically illiterate, based on available records that illiteracy wasn't relevant to the elements of the crime itself, namely that he "impersonated" (within the meaning of the law) someone else's identity to access protected information.

The id theft charge is the biggie here--it actually imposes more criminal time than the underlying offense itself, because as other posters have noted it changed a misdemeanor to a felony.
