I've heard a lot of claims about lucid dreaming among some young people I know well locally (some of whom post here from time to time). I don't get the impression that lucid dreaming is really as beneficial as they think it is. Some cases I know about from personal observation involve disturbing sleep cycles so much in pursuit of lucid dreams that the young people failed in work environments or crashed and burned in their university studies. Getting a normal amount of sleep (for you, that leaves you feeling rested when you wake up in the morning) is very important. It's a lot more important than what kind of dreams you have.

I read through the whole submitted article, and I didn't see any reporting on rigorous study of the waking state health or performance of long-term lucid dreamers. All we see in the article is anecdotes, summed up by

"For Hobson, the neuroscientist, the benefits of being able to achieve lucid dreaming are much simpler.

"'We don't really know if there are real psychological advantages, but I can tell you that it has huge entertainment value. It's like going to the movies and not paying for your ticket.'"

An issue to consider whenever participants on Hacker News discuss self-help strategies is how reliable the research base is. People who only use the University of Google Library to do research will often find websites by advocacy groups that are pushing a solution that may not have been tested. Fortunately, Google's own director of research, LISP hacker Peter Norvig, has written a guide to reading research reports

http://norvig.com/experiment-design.html

that reminds us all about what to look for when someone reports some new, amazing treatment. Check out whether lucid dreaming has really been well evaluated with sufficiently large sample sizes, control groups, and other marks of good research.

I think a writing intervention

http://homepage.psy.utexas.edu/homepage/Faculty/Pennebaker/H...

may do more for many people in high-creativity careers than lucid dreaming. There is a better research base, by far, for the writing self-help than for lucid dreaming. Try it and see how it works.

I've always been able to enjoy interesting movie-like experiences by DAY-dreaming, and it's not explained here why anyone should alter their sleep cycle (which has known risks, up to and including psychotic symptoms) just to be entertained. A lot of researchers over the years have done a lot of research on human dreams in particular and sleep cycles more generally. Where is there any evidence that lucid dreaming is helpful rather than harmful, long-term?

Best wishes for much success in improving your personal insight and problem-solving.
For people using mysql, that kind of query really isn't such bad SQL at all.
I think he addresses this point pretty well -- you can learn good programming practices through apprenticeship/experience without understanding the deeper fundamentals. You won't be creating the next MapReduce, but you'll be able to remix and hack up existing functionality in new and creative ways.
The Social Network was good about it. Someone online actually reedited the scene where he was grabbing images from frat sites and edited in scenes from other films, like Hacker's "virtual skyscrapers", and suddenly it was like a real Hollywood film again!

Bringing the life of the author into the copyright term just muddies the waters with respect to corporate copyright (since corporations don't necessarily ever cease to exist)

They've thought of that. Usually the law says "50 years from creation if the copyright is held by a company" or something like that.
Oddly enough if it did just fall, relative to the Earth's rotation, instead of slam into the atmosphere at thousands of meters per second it would be less stressful on the capsule.

The great benefit of the internet is that the capital required to start a profitable business is orders of magnitude lower than ever before.
It's all about recurring rev, make sure you've got a stable base of clients, good margins, and you're a minor but essential cost, and just ride the bubbles out.

Speed of setup is certainly nice and makes for an excellent demo but over time is almost totally irrelevant. As you note, far more important for a service to actually solve customer needs. If it had taken a half hour, a day or a week to set up but delivered increased sales, it would be much more compelling.

Doubly so for this bank transfer-based service which is already quite slow compared to credit card based services.

I doubt Cricket's going to unlock these, but their 4S is likely just as vulnerable to the unofficial SIM unlocks already in use. Even if Cricket makes you buy a month of service upfront, this could be a rather attractive option for thrifty AT&T users that don't want to be stuck in another contract.

(And that's assuming Cricket even bothers to SIM-lock it. I doubt Cricket has any GSM roaming deals like VZW and Sprint do; leaving it unlocked would make sure it's still usable overseas)
Agreed. Remember that big budget creative works (games, films, tv shows) are considered a failure if they don't make money with 1 year of release. Very people wait 10 years before deciding if something is a success or not.
And if you're in a position to tell your colleagues to go fuck themselves, then you can do what you want. The rest of us aren't so lucky.

Also, the cost of a Windows+Office license is so small that pretty much any company will happily buy it for an employee.

Why bother with an in-place upgrade? It should only take a couple of hours to simply blow away the system, install debian from scratch, and then restore config/data/$HOME from a backup.

Having done stuff like this in the past, I can say that it's an interesting science project, but you generally end up with a Frankenstein's-monster sort of system with "interesting quirks" that are always lurking to bite you later.
Well its creaking at the seams right now, I think given the progression of web technologies (even if they begin to use more hardware acceleration) it is going to become much slower over time as more intensive tasks are offloaded to the Hardware, its not an good indication at the moment that after a UI update its noticeably slower (at least for me) and a lot buggier.
yeah, something like this. But perhaps to a lesser degree.

Measure vs memorize misses the point.

It's understanding the relative order of magnitude differences between the activities that's important.
The article suggests that it is preferable to have an action under patent infringement rather than under copyright infringement because patents expire.

I think this is a gross over-simplification of the matter as if I were advising a manufacturer I would prefer to go down the route of copyright infringement as it would be a cheaper option than full-scale patent litigation.

Although this would be with the slight caveat that copyright infringement requires evidence of actual copying and will not succeed if independent creation can be shown.

I think it essentially still boils down to whether copying in this instance has actually taken place. In the instant case, I would love to see a comparison of the Games Workshop creations and the third party's creations. My guess is the third party works were inspired by GW rather than being substantially the same. In any event, it seems heavy handed of GW.

I would say overall that patent references are a red herring. In the instant case, GW will not hold a patent over each of the models of course. The focus on 3-D printing is interesting, but again it boils down to whether copying has taken place.

I would also add that under UK law, this would also be potentially dealt with under design rights law where protection is far more limited. In fact, because of mass production nature of the models, a claim would have to based on design right law rather than copyright, as they would not qualify as sculptures in my view.

If copyright term was 10 years (e.g. no metion of 'death'), then the copyright would be an asset inherited by your heirs, which would be valid for another 10 years. Simplies

"life + X years" can screw the public if you make something in your 20s and live to be 90.

I believe the answer to this is that you decide what you want to do in your dream before you go to sleep. If you do exactly what you planned, you were controlling your dream. If you were dreaming you controlled your dream, but you dreamt about what you wanted to, does it matter?
These numbers by Jeff Dean are relatively true but need to be refreshed for modern DRAM modules & controllers. Specifically, the main memory latency numbers are more applicable to DDR2 RAM vs the now widely deployed DDR3/DDR4 RAM (more channels = more latency). This has been a industry trend for a while and theres no change on the horizon. Additionally, memory access becomes more expensive because of CPU cross chatter when validating data loads across caches.

A potential pitfall with these numbers is they give engineers a false sense of security. They serve as a great conceptual aid - network/disk I/O are expensive and memory access is relatively cheap but engineers take that to an extreme, and get lackadaisical about memory access.

When utilizing a massive index (btree) our search engine failed to meet SLA because of memory access patterns. Our engineers tried things at the system (numa policy) and application level (different userspace memory managers, etc.)

Ultimately, it all came down to improving the efficiency around memory access. We used Low-Level Data Structure to get the 2x improvements in memory latency:

I have my doubts. I think there's more money in selling copyrighted content than in selling the fairly narrow range of products that can be produced with a 3D printer.

Looking around the room right now, the number of objects here that could be cranked out with any 3D printer is pretty darn small. For those that could, I doubt it would be any cheaper for me to 3D-print the darn thing, even if I already had the 3D printer, than it was for me to buy the real mass-produced deal.

The article's example of "little figurines" is the only example I can think of, and the little figurine industry isn't large compared to music or movies.
Perception is reality, and this applies to the smallest details. For example, most apps use a rotating circle spinner to indicate that it's busy doing something. The speed at which the circles rotate can make you feel like the app is working it's but off for you, or it's dragging it's feet.

A few years ago I interviewed with a company that made high end blu-ray players. They sold them for thousands to people with private jets and penthouse suites. It was a normal blu-ray player, but they put weights in it so it felt "solid".
I like Zen Coding a lot, specifically for CSS. HTML, it's ok, but not always faster IMO. The list example is a good one because I think it's an easy 'this is better' use-case, but for most things that don't require multiple instances of something it's not adding much (and that's ok, there's only so much you can do there).

For this nested table example, it's great. Another multiple instance example. There's probably no easier way to pump out that code so fast, but if it were a standard table, anything will do, even the hated (by most on here) WYSIWYGs, that could drop a customized table in a few clicks.

It's a pleasure - I'll delete this conversation now.
AirBnB attacked Craigslist users, not the website itself. AirBnB didn't post a copy of CP online. The spammed users could have tried to bring action against AirBnB under CAN-SPAM.
Obviously 37S has built up enough of a trust level with the employees to even experiment with something like this. That in itself is commendable.
Dan Pink talks about Atlassian and their "FedEx days" in his talks on intrinsic motivators. Seems like he should be using 37S instead.
It's illogical of you to not recurse and ask the question: "who designed the designer?" If you can't explain a complex system, then introducing a vastly more complex system to explain it is a terrible explanation, and hardly logical. It's intellectually dishonest to make such an argument, since it's so obviously flawed. No competent programmer doesn't understand recursion.

There's a guy setting up to experiment with morse code via eyeblinks: http://lsdbase.org/ I don't think he's quite got the hardware all done yet.

It's probably the best plan. It has been scientifically demonstrated that eye movements are under something like conscious control (for the relevant value of "conscious") during dreaming, as shown by the famous recording of someone's eye movements going back and forth very clearly, while the subject reporting watching a tennis match. There's nothing else you can count on being able to move; I'm not sure what typing you expect to occur in the real world no matter how strenuously you type in your dream.
But this is both.

Matrix 2 rather famously involved an actual ssh escalation using nmap. Takedown (aka Track Down) was another fairly accurate example of hacking (though highly inaccurate historically).

I follow the author's point, but I feel as though he's as guilty of dismissing valuable knowledge as the academics he condemns. I recently completed a graduate degree at a university that offered both a "Computer Science" program as well as a "Software Engineering" program. This is only my opinion, of course, but the difference in depth of understanding between the students in each field was very stark. The SoftE students dedicated several semesters to development best-practice-type classes: generating JavaDocs, curating JUnit tests, writing and revising good requirements, and UML modeling. They would essentially walk away from their program as expert Java users with little to no idea how Java itself (let alone the machine underneath) functioned. The CS students knew the inner workings of a computer program from code to compiler to stack, but would have to learn the bookkeeping side of development on the job. Both paths have their strengths and weaknesses and you've got to learn some degree of each to be a meaningful contributor.

Weirder still how the prompt clearly reads "mysql>" for Oracle.
I have noticed across the years since 2000:

- a bunch of nmap appearances (notably Die Hard 4 and the Bourne Ultimatum, also one of the Matrix movies)

- some default OpenBox with XTerms in a few series

- KDE quite a number of times too

- SSH, bash and Unix FS exploration (cd, ls -l and its output, find, grep) at times

In fact it's sad that so much of the computer scenes are bad, but I've seen enough actually good attempts at being realistic that I can't remember where I saw them. What's sure is that the trend is upwards.
What's terrible is that many Christians who claim not to believe the bible literally still pick and choose the few parts of it that are anti-gay to justify their homophobic bigotry. So "disbelief in the literal truth of the Bible" != "not homophobic bigot". I'd wager that Brendan Eich doesn't believe the bible literally, yet he's clearly a homophobic bigot.
WCF Service Creation With C#
I did not intend any offence, I too would like to see the source code for some of the apps I use to see what is going on under the hood.

Not sure how easy it would be to open them up given that cracked apps appear on jailbreak sites all the time, if the DRM can be removed there must be access to the source code.

If this is your cup of tea, have a look at Agner Fog's resources: http://agner.org/optimize/

Also, I'd have a look at Intel's VTune or the 'perf' tool that ships with the linux kernel.
I think you'd just need to access memory in increasingly larger increments (eg, sequential reads of 32k, 64k, ...2x size of l2 cache). But there's more to it as the L2 cache is often shared amongst cores in a multi-cpu system (where as the L1 is per-core). Also, the organization of the cache (eg, n-way set associative) means that you'd want to vary the size of the jump (stride) for your reads/writes and see how that also affects throughput.

planetguy, how do you know if you really have conscious control right now or just imagine that you have?

I'm not joking either.

The article mentioned the Hindu dream-yoga, the practice of which was meant to make you ask such questions on your "waking" life.
That story reminds me of something I did for a classical music e-commerce site I was working on. I needed to update the ID3 tags on MP3s and FLACs when the user downloaded an album (I couldn't do it in advance as a batch - arcane nonsensical licensing rules w/ storing digital content).

The problem was that it took too long to modify the files when the user clicked "download" after completing their purchase - they had to wait as the ID3 modifier chugged away doing its thing. So instead of waiting for the user to fill out their CC data and complete the sale, I started updating the ID3 tags as soon as the user put the MP3s into his/her shopping cart and cached the result. It didn't really matter much if the cart got abandoned, but the files were all ready for the customer once they got done checking out if they made the purchase.
That's not obvious or useful (and neither is notifo). Really it should email you about replies if you enter your email address in the 'email address' field.

To be honest HN is sucky in many ways (very buggy with crappy UX). Kind of ironic really.
Also "Rule 34" by Charles Stross is a pretty good novel about some of the consequences of personal 3D printing being pushed underground by regulation.

I found the comparison pretty useful.

I used to compose music solely by playing around on an instrument until I hit upon something that sounded good, but I had no idea why it sounded good.

I can still compose that way, but after studying music theory, I can compose directly from my head to a sheet of paper without any instrument, as (1) I can now envision in my mind what the music would sound like, and (2) I understand and can employ reusable patterns and concepts of composition that I know will sound good and work together.

Similarly, when I started programming, I had little overall vision for what I was doing. I just started writing code, and stopped when I had built up a pile of spaghetti statements that did what I wanted them to do. Now, with better understanding of design concepts and reusable patterns, the development process is much more clean and structured rather than poking around with guesswork.
Can you only have a lucid dream only if you were dreaming in the first place? I only infrequently dream - like once a month. When I do dream it's usually something really boring, like watching the water bucket (with a beach ball inside) in a well going up and down - and if I do realise I'm in a dream, I immediately wake, but paralysed for like half a minute... no chance to do any lucid dreaming. :(

I am feeling a lot of envy reading about everyone's experiences in lucid dreaming. :(
