Opportunity is always there, anytime and anywhere. The real questions are
1)if you can discover it.
2)if you are ready to catch it.

Few years later, when we look back, I am sure that you will find some "big" companies started at 2011/2012, which is NOW.
I love the first comment on the article:

Very insightful. That’s why the true entrepreneurs are considered crazy.

Like other entrepreneurs, I've always thought outside the box with pretty much everything... always questioning the why, the how, and what can be done to make improvements. Or sometimes I even gravitate towards seemingly outlandish ideas about the nature of the universe... things like that.

I can't count the number of times people have either looked at me like I'm crazy or just blatantly said, "Dude, you're insane." And it's hard to respond with something like, "Don't you notice that pattern throughout history? Every true innovator was considered crazy in their time!" without seeming like an egotistical prick, so I just respond instead with something like, "Yeah you're probably right." Even so, I've convinced myself that a large ego might even be required to believe that you can do something great enough to change the world for the better. And at this moment, I wonder, why is it that we're raised to believe that a large ego is a bad thing? Surely, tying ones ego to productive aspects of life can't be a bad thing as long as it is in moderation and no others are harmed in the process.

But anyway, thanks fellow hackers and entrepreneurs for helping me feel like I'm not so alone in my "craziness" after all!
Thanks for the clarification. Is the administrator role you describe something like a program manager (PM) or scrum master?

Would you say a "tech lead" is a manager? They have (technical) authority of the product, but not necessarily hiring/firing of other people.
Stifling innovation? There are have been music subscription services that provide all you can eat access to major label content for years. Most of them have struggled, at least two shut down and napster (v2) was acquired by Rhapsody in a fire sale.

In fact, you can get this service on your phone right now from Rhapsody for $10/mo. Assuming a two year phone life, this roughly translates into taking a $240 service and charging $60 for it (75% less).

Lets look at what that breaks down to in a simplistic model where half the fees go to the content pool and the four majors split equally.

Rhapsody: $120 / 2 (years) / 4 (majors) = $15/year

Oblivion: $30 / 2 (years) / 4 (majors) = $3.75/year

Compare that to something like $7 per title sold and you find that it'd only be clearly beneficial to a label in the case where that user would have otherwise purchased none of your music at all during that period.

What's that, a terrible implementation of an average idea? The versions of Open Firmware in the wild are notoriously buggy, often to the point that they are barely capable of more than booting the original OS designed for the machine.

Guys, I have to say that you criticize me a little harsh. But you are educative anyway, therefore I would not complain.
I actually did not use this script in any project, I sometimes write such scripts just for fun and I decided to put them on GitHub. I recently change my repo's name to weird-scripts and I put one more script (this one is a js script). You can see its new version in this url http://goo.gl/1g6k6 and I hope that you criticize this new code too.
Yeah, they still used sleeper technologies, but were only sleeping for 30 years rather than 100. But the universe takes the view that sleeper technology is dangerous and shouldn't be used heavily, it also only slowed down metabolism rather than freezing it ala stasis.
Not being sarcastic, I had just never seen one that low. I've flown only a handful of times (between SF and Missouri, usually booked about a month or two in advance), and the cheapest round trip option I had ever seen is $600.

Sorry, but no. If I was an unscrupulous host and wanted to boost my listing, the first thing I'd do is have a bunch of friends (or fake accounts) book nights on my listing and leave glowing reviews.

Doing a fast 3D engine is hard, even if most of the 3D is done for you. It's slow because it's simple, and because JavaScript is actually a fairly hard language to do some of this quickly in.

Also because web workers don't work great yet.
You can think what you like, of course. You're still intentionally generating OOB emissions. HAMs like you are actually dangerous to the hobby.

A U.S. Federal Standard exists (and is used in most of the world), that limits the amount of microwaves that can leak from an oven throughout its lifetime to 5 milliwatts of microwave radiation per square centimeter at approximately 5 cm (2 in) from the surface of the oven after sale. (at manufacture, the limit is 1 mW/cm2 at 5 cm.)

US Dept. of HEW, FDA, Bureau of Radiological Health, “Regulations and Enforcement of Radiation Control for Health and Safety Act of 1968” paragraph 1030.10; Microwave Ovens pp 36-37 PHEW Publication No. (FDA) 75- 8003, July 1974

Now, what's the EIRP of your setup again? Assuming a 50mW (17dBm) radio and 2.2dBi 'short dipole' antennas, and maybe 1dBm of loss in the connectors/coax, you're at 18.2dBm EIRP at the surface of the antenna. Call it 65mW for grins.

At 2450MHz, you'll be down -14.2dB 5cm away. 18.2-14.2 = 4dBm, so 2.5dmW @ 5cm. You're lower than a worst-case microwave (but higher than anything that's allowed to be sold!), unless you fit high-gain antennas or high-power radios.

Happy new year from Houston.
Jeeze, this is a great resource, why all the nitpicking? Thanks to Jeff Huang for assembling it.
When you don't have the privilege level to connect a debugger to the process or the secrets are in kernel space, it's probably easier to just reboot with a cold-boot kit attached via USB than to attempt some form of escalation exploit.
Inverted air cans or liquid nitrogen are entirely unnecessary in most uses of a cold-boot attack - they're only a requirement if the machine has some form of boot protection and it's desired to transfer the memory modules for some sort of offline forensic analysis.

As an additional plus, the tools which the authors of the linked paper have written for identifying key data in memory dumps are simpler to use than tracing the execution flow of even a simple application using a debugger. I'd probably use their approach even with full debug access, as obfuscating control flow around functions handling key data seems to be a more common practice than keeping said data obfuscated in memory.
My point is just, local attacker, "the call is coming inside the house!". You have big problems at this point.
I think you need to adjust for the fact that many of the tools that make remote employment effective are recent developments.
> If you are able to do this, it turns out that the global write lock really doesn't affect you. Blocking reads for a few nanoseconds while a write completes turns out to be a non-issue. (I have not measured this, but I suspect that the acquisition of the global write lock takes significantly longer than the actual write.)

Actually, it does affect you. I have worked with mongodb in production in a high-write scenario with about 1000 clients and it slowed to a crawl. All data was in memory. The server was not breaking much of a sweat. mongostat showed upwards of 60 queued reads/writes at any given time.

The only solution was to shard, but I feel like an enormous server like the one we were using should be able to handle 1000 writing clients.

Keep in mind this was version 1.8. I no longer work at the company where this happened and cannot testify to the performance of 2.0, but 1.8 has abysmal write performance.
Governments (decent ones at least) should be elected representatives of the people, surely that makes them the best body to supply honors? I personally wish the Queen would have total control in this area though in the UK, as she is technically still the head of state.

'merit' as a concept doesnt have to be in opposition to any of the qualities mentioned, i dont believe democracy is about abolishing hierarchy, as much as it is offering equal opportunity into it.

Ironically im more worried by Apple, which can manipulate customers left, right and center to make an extra buck:
- Overpriced hardware
- inconsistent pricing of products internationally
- making deals with telecoms companies locking iphone users to certain providers
- non-open platforms such as OSX and iOS
- taking the free out of freebsd

They are walking a close line themselves in promoting the anti-democratization of technology

thanks to this opening sentence, now I know everything I ever wanted to know about this system

In other words, your analytical faculties have been intentionally shut down.

I am pretty confident that a system not designed with concurrency in mind cannot be retrofitted with any decent concurrency later.

I think you're probably right from a software engineering perspective. But you haven't actually shown that Mongo was "not designed with concurrency in mind".

I've implemented in-memory persistent storage systems with a global RW lock. Depending on the characteristics of the load it can be ridiculously fast. E.g., on the order of tens of microseconds for typical transactions.

Complex schemes like MVCC with multimaster replication are an amazing accomplishment and are great for general purpose SQL-driven databases. But it's not the only reasonable design choice in the world and it's certainly not the optimal one for every problem.
Eduardo I can relate to everything you experienced this year, except that I'm from Mexico and I got to travel to Chicago for a job I landed. Here's to great 2012 much much better than this great year thats leaving us as we read!

Happy new year.
Understandable, then. Roundtrip fares are so heavily dependent on the individual route and when you travel. I did a quick search from SF to DC and got prices as low as $319, despite being considerably farther than MO. I often do roundtrips from DC to South Florida for under $200. But pick the wrong pair of cities and you can definitely be hurting.

This Sucks
Unfortunately, Depression and Mental Illness is part of the "curse" of being Intelligent. You name them, any great Innovator suffered. (Einstein, Niccola Tesla, the list is endless). Personally, I'm convinced it's because with intelligence, comes higher awareness of everything around you---which creates all kinds of problems. Even Darwin was not immune.....Condolences.......

Sounds like a great extension of the benchmarks provided in the article.
Well in the case of the game we were working on there was no choice other than fork our codebase. No considering the controllers (which is different enough from the consoles) the frame rate of our code base was awfully slow on IOS, so we had to rethink the whole project to target IOS properly. Actually I don't know any unreal game that sucessfuly have been launched on IOS and consoles with the same codebase, and after my experience with the engine I don't think you would like to do that in the sense that you always would like to exploit consoles capabilities. It's a tradeoff very hard to avoid.

That's great if it works for you, but I can't sit and "do" day after day hour after hour. I need some time to reflect. I need some time to explore a problem more deeply. I need to forget about "do" completely sometimes and just read a book about zombies. I'm far more productive at the "do" if I do something other than "do" as a supplement.
So cool to see him speak about his values reals rivet early on in his career, knowing that he stuck by them.
Darn, I was hoping for a response from scarmig.
I'd like to echo that sentiment.

From personal experience, I agree with the aane.org post that hackers may perceive the Cognitive Behavior Therapy framework as an authoritarian intervention on their value system. As the author puts it:

“ I value my own forceful beliefs and ubiquitous questions, my own Utilitarian sense of morality. Many of the theories espoused by cognitive therapists I simply do not agree with–and yet I am told what I must believe if I wish to get better. ”

A couple years ago I've found ACT ( http://en.wikipedia.org/wiki/Acceptance_and_commitment_thera... ) as a much more viable alternative, and thought I'd like to share it here. Here's a succinct summary of ACT's difference from CBT from Wikipedia:

“ Rather than trying to teach people to better control their thoughts, feelings, sensations, memories and other private events, ACT teaches them to "just notice," accept, and embrace their private events, especially previously unwanted ones. ACT helps the individual get in contact with a transcendent sense of self known as "self-as-context"—the you that is always there observing and experiencing and yet distinct from one's thoughts, feelings, sensations, and memories. ”

The "self-as-context" concept is particularly close to the flow experience we constantly experience during hacking.

I've since devised a mnemonic, based on the familiar Git workflow, that captures the essence of ACT's process to improve one's psychological flexibility:

* [Fetch] factual information
* [Merge] with understanding
* [Commit] to an action
* [Push] it out of mind

Hopefully it'd be helpful, or at least amusing, to HN folks here. :-)
I got minus'd a point for that? I still agree though. The first thing that comes to mind when I think of the "elite" spatially intelligent are professional athletes and race car drivers.

Value is subjective and some fields value traits that vary from what is valued in other fields.

To be a successful mathematician, you don't need to be particularly capable when it comes to spacial intelligence. The article highlights concerns but reality is different; the statistical analysis I conduct in a day requires very little spacial intelligence. The most productive athletes in my city do require a superior level of spacial intelligence and they are compensated incredibly well for their contributions (paid more in a year than I am likely to be paid in may entire career).

Hello, 2012 (or: Die With Your Boots On) And A Look Back At 2011
You need to spread enough photons per second across the entire area of the image to make it bright enough to see and look good. This translates into a fairly good bit of light.

As a thought exercise, consider a ridiculously bright 3 watt LED flashlight. Shine it through a 35mm slide to make a miniature projector. You now have enough photons to make something like a 3 foot image. You are going to need about 3 watts of laser to do the same job (no free lunch, except for green of course). A 1 watt laser is more than 10 times the power needed to instantly burn a permanent hole in your retina.
That's a very good point. It was a long time ago, so they used the old system back then and labeled it as a class IIa:

https://en.wikipedia.org/wiki/Laser_safety

I don't remember a wattage offhand and I no longer have that laser pointer, but I think it was under 1 mw. But there are other safety factors that can come into play, too. Mostly, it's a matter of how much energy is focused onto how small of an area for how long, not to mention how much of that energy is visible, which is why it's good to know the safety classifications.

There are dangerous lasers, after all and it's a bad idea to be cavalier about eye safety around those. In fact, I saw some just the other day in operation at MakerBench, where they were cutting plastic. The paper covering the plastic was getting set on fire... not something you want shining into your eyes.

EDIT: Reading your article scares me a little. I had a laser from a reputable supplier with an accurate classification. If they're selling crap with no filters like that nowadays, that's a lot more worrisome. People might own a laser that's a lot more dangerous than it's marked as being. Some lasers, especially cheap, "dim" green ones may not be what they're marked as. If it's cheap and not red, it's probably frequency doubled IR, so, yeah, beware....

time to boycott apress, and use dollars to vote for other well behaving publishers. Big companies are known to write contracts that favor themselves, rather than the little guy.
I'd like to hear what Peter Seibel's experience was with Practical Common Lisp, or some other authors. From an outsider's perspective, I've always been impressed that some Apress books continue to offer online versions for free, which suggests that Apress allows their authors to retain IP rights to their books. Can anyone comment?
Seriously, this has to be fixed. This is completely broken and a total failure of the legal system.

Mike, did your refusal to sign the contract (despite your continuing work on the project) have anything to do with the delay in payment?

Did you attempt to modify the deadline to a future date, and if so did they refuse to accept that version of the contract?
I'm convinced that most publishers are difficult to work with and actually care very little for their authors. It seems that O'Reilly really has some great people inside, and I really think the Pragmatic Bookshelf is a fantastic staff and author program. But for my part with the few publishers I've worked with, it's been nothing but hassle.

The issues with payment were annoying, but even worse in my case were publisher content control struggles. The book concept I was to work on was explained to me numerous times as "not a recipe book but an example driven narrative book." I think we discussed that at least 5 times leading up to the kick off. After I submitted the first 3 chapters, they suddenly shifted gears and gave me example outlines for the chapters that remained to follow.

They were freaking recipe chapters (problem/solution/discussion ad nauseum).

There was no discussion of this change, and any attempted further shift in content was met with "well we told you we hadn't worked out this series fully yet." They'd basically jacked the book out from under me and changed it to a book I didn't want to write. I think I wrote one or two more chapters and farmed the rest out to contributors. Terrible experience.

To make matters worse, I made very little money off of it because they didn't promote it at all. They never sent copies to conferences or user groups unless I asked them to. They never sought out blogs and other things like that to help promote it whatsoever. Part of the problem was they really sucked at promoting their books (other authors have had the same issues), but another part was that they had about 4 different marketing managers during the timeline for my book, which made coordinating efforts incredibly difficult.

So, yes, I think this gent's experience isn't totally out of the norm, even though I wish that wasn't the case.
