This is good advice BUT you really need to increase your joint mobility before attempting these lifts.

I would recommend this series of articles to understand the theory behind bad posture and how to fix it.

http://www.t-nation.com/free_online_article/sports_body_trai...

I would spend at least 2 months just improving your joint mobility (especially hip + ankle) before attempting deadlifts. And even then you should really have someone who knows how to do them correctly to coach you.

Else you'll seriously hurt yourself.
Companies such as Blizzard and Valve are rightly applauded for ensuring the quality of their games by delaying or cancelling them as necessary.

People also seem to conveniently forget that Vivendi Universal were actively trying to offload Blizzard a year or two prior to the release of WOW, because the studio was hemorrhaging money as a result of this philosophy.

It's a good way to be when you're continually producing titles that knock people's socks off - which 3D Realms weren't.

You can defend many things, but the fact is, they cocked it up in a big way. There's no defence against poor performance.
I second the recommendation for Starting Strength. Strengthening your entire posterior chain (hamstrings, "glutes", lower back and upper back will do wonders for your back problems.

Having said that, spending 1 hour a day fixing your problem won't be enough when you're spending the other 23 hours undoing it. Sit up straight or do as I did and get a stand-up desk.
i used to get back pain from working too much as well, but a chair solved that. i think i take more breaks now too, which was a factor as well, but the chair upgrades made the biggest difference. i love my freedom chair: http://www.humanscale.com/products/freedom_index.cfm

if an expensive chair isnt an option, figure out how to get good lumbar support in some other way, and make it easy for you to slouch, distribute pressure, etc....prob is , slouching in most chairs will result in pain, but when you work this much, sitting upright can only be sometimes -- thus the freedom chair. ted talk on the chair: http://www.ted.com/index.php/talks/niels_diffrient_rethinks_...
I would disagree with respect to hamstrings. Hip mobility and glute strengthening should be your focus.
Yes, sometimes I think that people get so carried away with trying to infuse their writing with character that they forget to check if they have one first! I just found the piece annoying, myself.

Though snide remarks aside, while I agree that the tone of the article is patronising and not at all befitting of even a semi-serious piece of writing, I think too much has been made of the dangers of genetic engineering in the past, and actually find myself appreciating the implied "It's still just a blooming virus!" stance. I mean, surely a virus with altered genetic material is about as likely to wildly mutate as one that's entirely 'natural' (whatever that means)?

There is no doubt that such a virus could be dangerous if it had been engineered, say, to be more resilient or to reproduce very rapidly, but I think people get so worried about the scary things that genetic engineering could do (if it wanted to) that they expect it to do so regardless of what is intended. The same could be said of the public perception of science in general, sadly enough - look at the way people have reacted to the LHC.
It's not about climate change - it's an analogy. It's not a choice between two evils either (you could round them up AND kill them). And of course you could propose a multitude of different solutions beside or in addition to these.

My point was that science cannot be used to justify all the choices you make in cases like these.
As a math person, I would like to get your response to this question:

'When's the last time you heard a math person refer to some real-world situation as "a real elliptic curve"?'

I imagine that "a math person" sees real world situations in terms of mathematical concepts constantly. Your thoughts?
I'm talking about incidental scripts included with programs for e.g. installation and regression testing, not scripts that encompass a lot of primary functionality. And, yes, it happens periodically enough to be considered a Linux-ism to watch for while porting.
Still...fuck off.
Fix your posture (most likely bad), stretch your psoas and hamstrings, and go and have an ART or deep tissue massage done. You might also want to invest in a foam roller for self-myofascial release and then use a tennis / lacrosse ball once that's not enough.
How is this different than wax thermal transfer, which apparently didn't catch on?

We had a wax thermal transfer printer at my department in college back in the waning years of the last millennium. I liked its output better than anything I've seen since, including our expensive HP color laser printer at work.
Fair enough, I stand corrected, I commented as I did because I interpreted it as a typical "science can't explain everything therefore it is useless" or "your theory isn't perfect therefore my theory must be correct" rant.
More like listing mistakes to watch for. I was mostly posting to note that the book was a much more in-depth collection of same.
I have a degree closely related to CS, and lately I have been trying to learn as much math as I possibly can (specifically, all of the math needed to understand the ideas behind machine learning).
"I doubt it though, I have too much stress."

I see the world as a series of problems that require solutions.
* Abs and Back Strengthening *

- These are simple and only need a yoga mat and 10 minutes 3 times week. Even 1 session a week will kill a lot of back pain

- I will ignore situps here, because they're simple

- Get yoga mat.

- Lie _face down_, legs and arms outstretched

- Raise your _left_ arm and _right_ leg, so your body evens out

- Lower left arm / right leg

- Raise right arm, raise right leg

- Lower and repeat ~ 20 times

- Now switch to the situps and do 20 of one of the many varieties you can do.

- Alternate situps with prone swim, as the core muscles exhaust after 20 repititions. Keep both abs and back at same level to prevent hunching.

* Ergonomics *

- Get a foot rest

- Get an Aeron chair

- If you're right-handed get a left handed keyboard so that your hand does not have to travel over the numpad to reach the mouse. This extra travel distance can really hurt over time

I have a Evuloent http://www.evoluent.com/kb1.html

* Stretching *

Mentioned elsewhere, do your quads as much as possible
Sometimes I think that people get so carried away with trying to infuse their writing with character that they forget to check if they have one first.

Brilliant quote, love it.
I'm going to have to go with the AOL comment on this one. I had both upper and lower back pain. A proper understanding of how my back can get pulled into awkward positions and what stretches/posture corrections are necessary to prevent this has eliminated it thus far without having to make any equipment changes (buying new chairs, desk trays, etc.).

Tim Ferris also recommends changing your shoes (http://www.fourhourworkweek.com/blog/2009/05/07/vibram-five-...) or your chair (http://www.fourhourworkweek.com/blog/2009/01/27/office-chair...) if stretches/exercise doesn't cut it for you.
Even worse, it's one of those stupid slideshows that loads a new page every few seconds, even when you're not looking. When I looked at it, it was halfway through the list of "states with highest alcohol and tobacco taxes".
No it's not a misquote. Yehuda detailed his benchmarks agsinst PHP during the Merb Camp Keynote. See these slides: http://www.slideshare.net/wycats/merb-camp-keynote-presentat...
I get back pain every once in awhile and it tends to linger for 1-4 weeks. Then it goes away for a month or two.

I try to work my abs and lower back, as well as stretch my hamstrings.

As for sitting up straight, I think the most recent guidance is that a 120-135 degree thigh-to-back angle is optimal: http://news.bbc.co.uk/2/hi/health/6187080.stm
I risk being misunderstood as rude, but with all sincerity, I couldn't make out what your response is all about.

US VC investment halves globally
Yoga has made all the difference for me. It is a great way to unwind for a short period of time and with practice it will greatly improve your core strength and relieve your back pain. It doesn't help that it is also a wonderful opportunity to meet new people, especially flexible girls. :)
Although I agree entirely, the direct answer to your question is: Because that's much more difficult.
Flyposting is by definition illegal ("Flyposting is the act of placing advertising posters or flyers in illegal places"), but that doesn't answer the question about whether these particular ad billboards are illegal. The question is whether the original billboards were placed with the permission of the property owners.
It will become a mix of free and paid services. Broadcast TV was free in the US (ad supported) because it was impractical to bill for usage. Now the cable and satellite rule the roost, we pay for some channels (HBO, Showtime) and some content (on demand) while others are still mostly ad supported. The HBO model is not for everyone - would you pay $20 a month for the scifi channel? I don't love Boa vs. Python that much.

The net is a mix too - I pay for web service and email service, event though there are free alternatives. If iphonedevsdk or stackoverflow changed to a fee structure, I'd join. However, if Facebook or Reddit or went paid, I'd stop showing up.
...basic CS concepts...

Something which is ironic, and also gets back to basic CS concepts, is that modern scripting languages have added so much power to "Regular Expressions," that they are no longer strictly Regular Expressions. They are no longer equivalent to Finite Automata. "Regular Expressions" in many cases are outright Turing Complete.

And so the abuse of our field's terminology continues.
You're right on the money. Granted, it's a movie - but that's exactly what happens in I Am Legend. They modify viruses to cure cancer, and because of the perceived benefit, the risk is overlooked. The virus is tried, and it turns out to be highly contagious and deadly.

Moving back to the battery, what if there was an accident / spill, and the same genes that made the battery acids causes some infection in humans or even live-stock? Doesn't that come to the writer's mind at all?
Sitepoint website sales.

Also, this is not good: Our traffic has hit up to 75,500 monthly visitors, averages 40,000 but currently is at 6,000.
I posted this on the post, but does anyone else think he was looking for some sort of 15 mins of fame?

Emailing the press with other peoples' email addresses without notifying Facebook first seems like it was the wrong thing to do. I'm sure Facebook would've liked to fix it before the press (and spammers) got to it.

Seems like he wanted to guarantee that his name would be in some newspapers

Many people on this thread are suggesting a math degree instead of a CS degree if you're 'on the fence'. I was on the fence and got a math degree, and I disagree.

Perhaps math programs are far different at other schools but here are some of the classes I was required to take, along with a few electives: real analysis, abstract algebra, "foundations" (more abstract algebra), knot theory, topology, algebraic geometry, number theory and so on and so forth.

You'll note that almost none of these are applicable to anything unless you're doing very abstract research. It's impossible to get a job doing anything useful related to these topics with an undergraduate's understanding. It's probably impossible to get a job in these fields with a phd's understanding - math phds have the highest unemployment rate out of any phd, but that's another discussion. If I hadn't been a campus Perl programmer in my spare time I would have been unemployable like the other math majors who didn't take teaching credential courses. The only math I've really used much as a programmer is linear algebra, and perhaps "discrete" math which I didn't learn about in school because that class was offered by the CS department...

In contrast, every job interview I've had they've asked the same algorithm and big-O questions. Those first interviews would have been less embarrassing if I had taken those classes in the first place.

If you're on the fence, don't want to do CS, and want to major in something technical which is not only applicable to every scientific field as well as economics and finance and Google and Paypal, but is also in short supply, major in STATISTICS. Learn C, Python and Matlab in your spare time and take the intro algorithms class from the CS department. Good luck.

This scheme sounds exactly like old state of affairs under the Classic Mac OS back during the 68k era. Macs back then had no MMU, so the OS provided a surrogate "Memory Manager" that abstracted away pointers into handles, which could be marked as purgable, required checking if the memory "moved" due to heap compaction, and so on. As clever as it was at the time (the original Mac fit in 128K, not M, K!), it just proved too limiting and error prone and held down the platform until it was partly jettisoned by OS 8, and fixed for good by OS X.
I know. Should I take it out or leave it in for full disclosure?
Now contrast all of these people to some other groups with just a high school diploma. They might not even have the options open to them of becoming a house husband, or never met the people in college who became the connection for a job at a Web 2.0 fashion site.

Getting graduate degrees learning stuff that you cannot apply to gainful employment may seem a waste, but it is difficult to predict how educational opportunities will benefit you.

That's a pretty good advertisement for the benefit of a good math education, actually.
I'm not understanding how this metric is useful. If I start a business and it goes bust within three months, and then I start another one, do I get counted twice?

I often kick myself for not taking Statistics more seriously as an undergrad.

Maybe a Stats/CS dual major is the ultimate?
Major problem with the business plan competitions I've been to is the IP. One Conversation went:
presenter: its a great idea.
judge: so what is it.
presenter: i can't really say, just trust me.
On the flip side, when a friend of mine won a competition he then couldn't patent it, as he had declared it in a room full of people.
As a result, most of the more open competitions tend to focus on quirky ideas, that could not be patented anyhow. I often find they are little more than pr exercises to lift the profile of the entrepreneurs society and/or business school, not bad in itself, i guess, but I always get more of an institutional feel about them.
When people are happy, they do good work. Understanding the human condition is a surprisingly rare trait.

More companies need to take notice.
It didn't take 9 years though - as far as we know the original TF2 was put on ice to focus on releasing Half-Life 2, and work didn't begin proper until that game was released, at which point they scrapped what they had in the first place.
"When a math ABD starts telling me about how she really likes her work but is sick of the slow pace and the fact that only six people in the world understand her work, I get to take a nice minute alone with my thoughts: I've heard it over and over again, in the same words and the same weary, beaten-down tone."

It's interesting to keep this in mind when reading Kaczynski's "Industrial Society And Its Future". He spills a lot of ink on how humans in industrial societies waste a lot of time and energy on "surrogate activities" rather than focusing on their own survival (which is no longer a challenge). It sounds a lot like the frustration of an academic who sees no use for his increasingly arcane work.

That is just really cool. We need more parents like that who can spend the time to teach their kids about general relativity. Seriously. Too often parents either ignore their kids or brainwash them with their own narrow minded cultural take on the world. Very rarely do the actual facts about the actual world get passed along. Maybe parents just rely on schools to do it, but any kind of passing along of enthusiasm about the natural world is highly commendable. Bravo.
I'm not sure the author is sufficiently familiar with the iPhone's memory management. The iPhone will terminate a user process if it consumes all available memory before the OS' low-memory handling has triggered low memory warnings, causing (in this order):

- Running processes (including background processes) expunge caches, non-visible UI, etc.

- Termination of Safari and Mail, which are kept running to improve the user experience.

In reality, one can use up to approximately 40 megabytes of RAM without triggering an application failure, as long as the memory is not allocated and used before the OS has time to free memory by warning/triggering background processes.

While this is more complicated than a guaranteed minimum available amount of RAM, it does permit applications to consume (and rely on) a relatively fixed amount of RAM, and seems a reasonable compromise on a multi-purpose, non-console consumer device.

The concern when writing general interest stories about scientific topics is that you will either a) alienate an unsophisticated reader by maintaining a serious tone or b)alienate sophisticated readers by trivializing a serious topic using a whimsical tone.
I am not sure an idealized middle ground really exists. That we are discussing the article on ycombinator probably reveals that we can only speak to the interests of one of those two groups (presumably b).

I am unsure whether Swombat is more infuriated with the general unconcerned tone of the article or the actual paragraph (s)he dissects. In either case, the concerns for this particle application of virus-based technology are minimal. As pointed out, the genetic modifications are small, the viruses are fragile, and the materials used are ions in water. Though we (humans and most mammals) live in symbiosis with many types of bacteria, bacteriaphages are generally a species-specific predator. M13 will not consume your digestive bacteria any more than a polar bear would hunt krill.

Gray goo, though a well used and thought-out science fiction conceit, is about as likely as the Decepticons in this case. Again, most gray goo concepts (there are dozens) require a fairly resilient mechanism that consumes a wide-variety of materials and converts them into more goo (or goo-related materials). The M13, modified and self-replicating though it may be, has a narrow range of consumables (iron phosphate and SWNTs) and is fairly easy to kill off. In fact, it is unclear whether M13, when modified, is sustainable outside of lab conditions.

In general, I feel that most media are too quick to produce alarmist articles in relation to new technology, and that anti-alarmist articles (even ones lacking character) are a welcome balance to the discussion.
Consider the word ‘smashing’. Using the above regular expression, the regex engine will first try to match the pattern ‘hi’ in ‘smashing’. It will not find a match.

Yeah -- chair, general ergonomics, excercise, stretching, massage. All good. All mostly missing the real point.

Unless you've suffered a real back injury, your pain is probably at least partly psychosomatic. That doesn't mean "in your head", but "FROM your head" -- there is real physical pain caused by real physiological phenomena, but the major contributing factor is unnecessary muscular tension. BLOW OFF STRESS. Laugh. With friends if possible. Hit things that are designed to be hit and don't mind it at all. Drink in moderation if it's safe for you to do so.
This is an important article following up on the many studies of serotonin-specific reuptake inhibitors (SSRIs) from the 1990s. It turns out, as usual, that the drug companies were quick to publish studies favorable to their products, and slower to publish studies unfavorable to their products. See the excellent article by Peter Norvig, director of research at Google, on how to interpret scientific research,

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

for more on this problem of publication bias.

There is a good body of research now suggesting that most patients with depressed mood and related symptoms can be helped by cognitive therapy.

http://www.aafp.org/afp/20060101/83.html

http://www.apa.org/divisions/div12/rev_est/cog_depr.html

For many persons suffering from depression to the degree that it interferes with work or with family relationships, the best approach will be to combine medical treatment, possibly with the new first-line drugs (SSRIs) or possibly with other drugs, and cognitive therapy to learn new patterns of thinking.
I hadn't seen recursive regex before (almost a tautology). The operator in the article, "(R?)", isn't in Perl (v5.8.8).
My boss and I just bought iShoot last night while at a conference in San Diego. (SNC Knowledge09)

I showed him the Lite version at dinner, and then we both bought it and had some fun multiplayer games. I wouldn't have had it if not for the lite version, to end up justifying the full buy. The impact of a demo is definitely not overrated.

(Trying to get him into Worms next... here's hoping!)
A potential buyer wanting to know what your traffic "was" or "once was" isn't something that should necessarily come up. I'd tell buyers your traffic is 6,000 uniques, and leave it at that. If they ask about the past use the 75K number then (and only to highlight the potential of the site, not what it 'once was'). The way it's phrased now looks like the site is heading south.
Look into the ideas and books of John Sarno. He believes that many chronic pain "syndromes" that resist treatment are actually psychological in origin.

I discovered Sarno when I came down with untreatable "RSI". Eventually I got better using his approach. My story is similar to Rachels (google for others):

http://podolsky.everybody.org/rsi/

Sarno originally worked with people who had chronic untreatable back pain.

All that said, if you're not getting any exercise I would try that first. But if you have tried that and a bunch of other things and nothing works, look at Sarno.
I wish HN had downvotes for articles instead of harsh top comments.
