"Summary: Bryan Cantrill [from Joyent] discusses debugging production systems using post-mortem debugging and dynamic instrumentation, with a bit of history and an introduction to useful debugging tools."

Some very interesting stuff here, including debugging Node.js programs from core dumps using debugger extensions that can display the JavaScript stack.

I use equivs to create a virtual package that does nothing but depends/recommends/suggests other packages. I have two dfc.deb and dfc-workstation.deb, dfc-workstation adds GUI/multimedia/end-user tools that I do not need everywhere. When I get a new machine I can install these packages and all of the things I depend on will be installed. If publicfile was in debian it would be automatically installed. As it is I have to copy the package I created with checkinstall and install it manually.
That's pretty much the method I used to solve it. You aim for the right hand corner using only right and down moves. Your goal is to keep the rightmost column fully merged. This allows you to make the occasional 'Up' move when you need to merge tiles from the third column into the rightmost column.

You should not make any 'Up' moves unless you absolutely have no other move. You should not try to merge large tiles from the bottom of the third or second column into the third. Just let them build up on their own and eventually the top of the columns will be able to merge together and you can then merge the rightmost tile and fill it up again.

First priority is to keep the rightmost column completely full.
so are both of you aiming for mobile games or are you also considering a PC Indie game?
Happy is too fragile and illusory a state. Content works much, much better and I find myself remarkably content considering the heights I reached and the bottom I barely pulled myself out of. I don't miss the bling at all and am very pleased with how little it takes to make me content.

On the content scale I'd call it a 7.5. Happy I no longer understand and am very wary of.
"Machine learning" and other techniques have actually been pretty effective at reducing card fraud in recent years -- an overall loss of just 0.07%.

And this is all done with a system that is very convenient for consumers to use correctly for everyday use, without significant risk of a total loss due to getting hacked or having their password or other security factors compromised.

Personally i think PC gives you more creative room. While the touch interface is really cool for some games, but it also limits the gameplay IMO
As my account is new I'm having trouble replying to comments ("You're doing that too much!"). I promise I will reply to you all - thank you for all your fantastic feedback and security tips. We've started implementing some of these changes.
Keep in mind credit cards offer 1-2% rewards. So in the end it's probably a 1% effective increase. Bitcoin exchange fees are usually about 1%. And that matters unless the merchant is not ever converting his Bitcoin into other currencies, since he would pass on that cost of business to the customer as well.

Oh and of course they'd have to offer a discount to Bitcoin purchasers since they're covering the additional CC fee cost anyways if it's the same price.
I both despise and admire 99designs. Let me tell you why.

From the point of view of being a business, they did a very good job. They went for the lowest end of the market, where at a typical price point on 99d, clients don't require a lot of hand-holding. Instead, the illusion of value is delivered to clients by the fact that many designers compete to create something for you. They have captured the cheap-and-fast market well.

From the point of creating value, however, I am really not a big fan of 99d. I do know some people who had some level of success there, but I know a lot more who spent money only to get back some very crappy results.

The mechanics of a cheap marketplace simply don't allow for value. Designers have no incentive to spend time working for you, because the odds of them getting paid are really low. They are, in fact, incentivized to produce the bare minimum at the fastest speed possible.

At the end of the day, you may feel like 20 people worked for you and one was the winner, but in reality, you only got the minimum attention and effort.

Out of curiosity, why would you need to bind an arbitrary IP to a VM? What's wrong with the one it's presumably got?

I know some places can move IPs around at will, but it seems like the wrong layer in the stack to do it. Aren't IPs something you want to assign based on your network topology? If you need an arbitrary identifier that can move between machines, what's wrong with DNS? (And how are you not re-inventing DNS?) (and the names are more memorable)

If you do have the capability to do this, does it not tie you to that provider? Presumably the IPs would be allocated to the provider, so switching to a new provider would necessitate a new IP, whereas DNS addresses can point anywhere.

Unless I'm completely misunderstanding (I've never tried these shenanigans with IPs), so please correct me if I am.
Not my finest hour.. Lesson learnt - valid point, and I will make certain to be more security conscious moving forward.

I see ScoutJet in Yelp's Robots.txt file. I guess I'll have to ask them nicely to allow my crawler too. But Yelp is one of many sites that don't allow crawlers so I'll have to ask each one nicely to allow mine. I had even set up a temp google site explaining what my crawler uses the data for (essentially showing results with correct attribution and driving traffic back to original site).

If they got an improvement of 116% perhaps a spinlock isn't the right solution? It sounds more like the subsystem protected should be autonomous and respond to messages in a message queue instead.
Economically speaking, everything is a scare resource. But more importantly, a unused domain does not cause any damage, as say a derelict house would. I don't find the metaphors compatible.
The blame for the fiasco needs to be placed where it belongs: on Matti, not on the people who hired him without perfect foreknowledge of his future actions.

This is absolutely true, so far as blame goes.

But the people who hired him were responsible for him. That's how business works: a business cannot just reject responsibility for the actions of people acting for them because they subsequently find out they did bad things. The business can (and should) try to correct those thing, but they are accountable for it.

And this mistake is already punished by law and custom more harshly than it should be. The result is that employers are incentivized to err strongly on the side of caution, to never give a candidate the benefit of any doubt, no matter how ill-founded.

And this hurts everyone. It hurts good people who can't get a job because there's no absolute proof they'd be good hires. It hurts good people being abused by sociopathic bosses because they're afraid they wouldn't be able to get another job if they were fired. It hurts good people being paid below their worth because wages are bid down by the desperate. One way or another, it hurts you, and it hurts people you care about.

I disagree with this. Yes, employers should be able to take risks on people, but at the same time a business can bring powerful resources to bear on something, and in the wrong hands those resources can be dangerous. A business absolutely should consider this when they hire, and should be held accountable if they make a mistake in hiring.

SIP is currently supported on the outbound leg. Definitely the plan to integrate with other telephony products and hopefully by going the open source route we'll be able to make it happen sooner rather than later.

Thanks for the feedback.

"We know from countless discussions with our hosts that they want to pay taxes, but some of these rules are arcane and difficult to follow. Some hosts have even tried to pay taxes in San Francisco and been turned away."

I find it hard to believe that any host voluntarily said "Please, take my money because I want to pay more taxes!" This is akin to someone actually reporting their out-of-state online purchases on their income tax return.

Seems like a somewhat risky move given that they're admitting they are like a "hotel" in which case they may also need to adhere to safety rules (fire escape posted, etc.) that hotels have to comply with as well.
Can anyone comment on value of patent and potential licensing revenues.

I found one patent holder [1] but I assume they are several others that can claim and request licensing fees.

I've driven several cars with a backup camera and never used it, instead I used my eyes. Maybe I'm just not used to them since my main vehicle doesn't have one, but I feel like the one time I need it to work it will have some sort of lag/delay or a blind spot and cause me an accident if I trust it.
Thank you - this comment is buried but it's excellent advice and I will be taking it seriously. Currently chatting with one of the co-founders of Plivo so watch this space :)
If you can lose your card you can lose your phone too. You're proposing accessing your blockchain.info wallet via someone else's web browser? Sounds like a great way to get your entire wallet stolen.

As for the inconvenience of getting a false positive fraud flag.. that's extremely rare, usually resolvable with a phone call, and probably an overall vastly more convenient way of protecting you than more inconvenient up-front authentication steps for each transaction.
Waaah! ... several minutes later and I realize what it is by glancing at the start-end date/timestamps.

Even the book they linked to seems odd, including all the review statements.
See my comment to the person above, /re why competitions are soul-sucking experiences for designers.

Also, to your point about charging 50%+. Word is, 99Designs used to do very well, up until the point when the founder took on a huge VC investment and left the company. I guess since their business model is pretty much tapped out, they figured that raising margins would fix the slow growth.
This is really nice. As someone who has worked with the competition libs masonry, packery, and gridster, I know why you built this and it looks great so far. All have their oddities or missing features.

Can you sort items on this programatically? If so very cool, its one feature packery is missing.

On feature I (need) think is missing is the ability to freely place an item in the bottom-right side with gaps in between it and other items - for example in the bottom right corner of the parent container. I could really see this being requested in a dashboard type use.

I wasn't aware of Affero GPL, will look into it. I've had some conflicting advice when it comes to licenses. Some are recommending BSD as it's more permissive (i.e. big companies can develop it in house without having to give back to the community). From a business perspective, that might be easier to sell to some companies, but from a community perspective it's not ideal.

Would be interesting to hear your thoughts.
Great! I love that sort of IAPs.

Some things i really loved about the devs of BADLAND are that not only did they provide a huge amount of free content before the paid expansions, but the expansions were absolutely worth it! Further more they recognized the existence of a particular audience segment that would get absolutely hooked to their game and would aspire to be the "hard-core" ones. They rewarded them by providing challenges that would unlock the premium content. And while these were reasonably tough, they were also doable.
One of the ideas behind of "Trillek" game is having a computer were you can do anything like could do you do in a old computer of the 80's. So, is possible know everything about this computer for a normal personal.
https://github.com/trillek-team/trillek-computer

Obviously , the trick is that we have a computer defined by the emulation software and not by real hardware, so it allow to make some short-cuts and simplifier some stuff that in a physical computer will be more problematic.
Using Third-Party Code in iOS Development
Dear Pixelfold team, the graph icon above "2. The community votes" on the site looks like someone's showing a middle finger! You may want to change it, considering the impression you want to create as a community of top designers.
Yeah, exactly the kind of news I was expecting on April 1 ;)
Potentially true, though I would imagine it depends on the size of the initial pool. Otherwise, if its small, I think you'll see bias in the selection of the early members which will carry forward.
Interesting fact: Australia regulated away credit card fees a few years ago. There was no corresponding decrease in consumer prices.

In any case, even if there is an increase, unless merchants offer differentiated pricing by payment type (they generally favor simplicity) then what I'm saying holds: there is no additional cost to using cards.
I for one want a browser created by people who value free speech and privacy rather than by people who severely punish the slightest misstep.
The fact that some employees urge him to step down is therefore concerning to me. Will these people support handing over my data when it suits their ideological whims? Will they insert backdoors for that purpose?
It depends on who I'm pitching to - if I'm talking to a CEO of a company, they're less interested in how it works and more interested in how it's going to make/save them money.

What is call tracking? It lets you track statistics and recordings of inbound phone calls (usually from your customers) so that you can identify trends, strengths, weaknesses and understand the performance of your sales and marketing campaigns.

Time of day, day of week, failed calls, total calls, caller id, caller country, call duration, hangup reason - all these stats and more are available.

Why do you want to migrate away from Sybase? You'd be giving up a lot of capabilities moving to Maria/MySQL.

Given the common ancestry, your easiest transition would be to SQL Server. But if your reasons are to get out from under from vendor control, that isn't really achieving anything.
>I'm thinking C++11 and Qt with python as the scripting language

I was thinking it would be cool to do it in pure python, or if that ended up not being fast enough, something like Rust/Python. If we're doing an entirely new codebase, might as well do it right from the start!
Have read this myself, and can confirm it's pretty solid stuff. Also, the writing style has an admirably high information density. He cuts to the chase.
Restate my assumptions: One, Mathematics is the language of nature. Two, Everything around us can be represented and understood through numbers. Three: If you graph the numbers of any system, patterns emerge. Therefore, there are patterns everywhere in nature. Evidence: The cycling of disease epidemics;the wax and wane of caribou populations; sun spot cycles; the rise and fall of the Nile. So, what about the stock market? The universe of numbers that represents the global economy. Millions of hands at work, billions of minds. A vast network, screaming with life. An organism. A natural organism. My hypothesis: Within the stock market, there is a pattern as well... Right in front of me... hiding behind the numbers. Always has been.

Understanding the JavaScript delete operator
"Disgusting trolls" is, I think, a fair description of their online persona, as the chief characteristics of their behaviour appears to be sexism, bullying and cowardice. Now, that's not all of who they are, and as human beings, I accept that their actions are symptoms of underlying problems (well-adjusted people don't normally engage in this kind of behaviour), and I wish them to get better, this attitude is toxic to both their victims and themselves.

This is true but the opinion in MGM v. Grokster is pretty clear:

You risk being held liable for contributory infringement if you advertise infringement as a possible use for your product.

There really is no other way to read that case, and despite technical differences between Ginsberg (really, really bad) and Breyer (really, really good), all 9 justices on the court agreed with that basic idea. Advertise infringing uses? Get held liable. What this means is one really should shy away from saying things that may be taken as advertising infringing uses.

You can read the whole thing at http://www.law.cornell.edu/supct/html/04-480.ZS.html

Please do so.
If I had infinite time and patience, I'd tinker with this to show the differences in socket code, specifically with the approaches outlined in the C10k document.
