when it comes to programming knowledge. Books are ok, but they are extremely expensive.
When it comes to many other subjects, I tend to turn elsewhere, like books. (or I would prefer to).
Wikipedia provides some good knowledge, but I generally can't find enough in depth information on some subjects on the web. The web is good for quickly finding information, but you can't allways be sure of it's reliablity and accuracy. Many students are not allowed to use or cite web pages as references, it's accepted that the inforamation is not as reliable as say, the New England Journal of Medicine. If you read the journal online however....
solutions pulled from my ass.
I don't tend to think Java is your problem, and what you are suggesting with the static content/caching/PHP is not a step forward by any means. In fact it sounds like a suggestion from your sysadmin, who is probably a PHP fanatic and does not know any better. Don't know how many times I have had to smack our sysadmin at my company for saying: 'Why does it have to be so complex? just do the whole thing in PHP!'
For most people complex means any thing but [insert the only language you know here]
I for one think:
1. PHP is not likely to solve your performance problems. It is recompiled every time you hit the page, its not scalable, blah blah we all know the limitations.
2. As suggested somewhere above: Profile you app.
Find out if your code just sucks, and fix it.
3. Chances are, you are not taking full advantage of J2EE platform. This is very likely.
4. Your hardware is probably old. Upgrade. I'm guessing you have a big ol' sun box with couple of 750 mhz processors or something old like that. Yes, its a nice big pretty box; yes, it cost you $126,000 and yes, its mostly filled with air. Good luck trying to pawn it off. You can max it out for a few hundred k more.
5. [licensing/costs] Sun/Solaris is Expensive as Hell, so too is your J2ee server. Try a bunch of cluster of intel boxes running JBoss on Linux. Can't get much cheaper than that. You could get a whole farm of these for the price of that sun box. (or you could have, but didnt.)
And depending on which J2ee server you are currently using, you wont have to rewrite anything.
6. Oracle is pretty scalable, its relativly fast, but if your code sucks, its your fault.
Is java slow, or does your code suck? You might just want to make better use of what you have. I am a big advocate of Java and open source software of course. Its always worked for us. There is no reason you should'nt be able to do what you are trying to to with Java/J2ee.
There are many reasons why other platforms won't cut it, mostly because they were not designed to.
I guess the target programmer here is one that is just being introduced to UI design. What I would like to see is more UI design patterns and practices in a book like this. It's one thing to design a UI that is nice to users, but to design one that is nice to the developer in the long run is more difficult. (This would apply to application development in general)
He's obviously winking. Have'nt you ever seen a spider wink?
Ignore his advice on gloves

The "Spider Case"

I stuck my middle fingertip into a table saw and found out first hand why people wear gloves.
Wearing gloves while operating power equipment is dangerous and will not keep you from getting your fingers chopped off. If you are dealing with powertools like table saws or band saws, there is a good chance you will lose a digit or two. It's almost inevitable. You will learn to deal with it. If you want to lose more digits or your whole hand, wear gloves like the article suggests, and long sleeves while your're at it. Might as well get your whole arm sucked in.
..of the 2 day workweek. Monday is not so bad when you know the work week ends tomorrow. And we all need to do our part to limit the impact we have on the environment. Ill have to bring this to the boss's attention.
Agreeing with you here, except for one thing. CMS and CRM/ERP can be done in PHP, as long as you are not expecting huge amounts of load. For a company like mine, with 25,000+ employees a PHP CMS for our intranet or web sites would lead to disaster. Also, maintaining a PHP CRM or ERP system would not be feasible.
I dont think many people would be migrating applications to PHP. Migrating from cold fusion might be a step sideways, but thats questionable. If you are going to migrate an application upwards, it will be towards J2EE these days (or for some,.NET)
I dont know where you would be coming from to want to migrate an application UP to PHP, unless we are talking from a non web-based app.
this is probably a little off topic, but who has the crappy job of monitoring chat rooms? I thought my job was getting boring. Eventually this should mostly be handled by AI, but until then, someone actually has to do it. I remember thinking the same thing back in the early days of monitored chat rooms. How does that job work? Are they on salary? Do they work from home?
Soon is a relative term. Do a fly-over of parts of South America. All the little patchwork abandon plots used to be rainforest, the plots that are being used are freshly burned rain forest. Burning the vegetation provides very rich soil for a few years, but 'modern' farming methods make the soil useless after a while. So, more is burned, cash crops are produced, your local supermarket is stocked with food, biodiversity decreases, everyone is happy. You are an idiot.
Well, only an Office product could handle that initial processing instruction.

And where are the o and w namespaces declared?
While its very XML like, it can't really be parsed by a standard XML parser without some modification. It still looks like this format was adopted because
A: Microsoft is pretty good at marketing.
B: Word's old format was krufty. Might as well XMLize it, wouldn't want to be behind the times.
Really, couldn't they have gone the extra small step to make it readable by other parsers?
The tired argument about volcanic eruptions misses the point completely. We are not capable, nor is there a need to control the environmental damage from a volcanic eruption. We do have the capablity of limiting our impact on the environment, and even living in harmony with it. Some people would argue that human pollution is a part of a natural process on this planet and is therefore OK. This is true, and like other life forms who out-grow or over-toxify their environments, we will naturally destroy ourselves and much existing life as we know it, allowing a new cycle to begin where we left off. Even if there is a possibilty that global warming is not related to our impact on the environment does not mean we can continue to ignore the impact we have.
At the rate that the existing rain forests are being depleted, there soon enough be none left to process all that CO2. Then it will be left to the plankton/phytoplankton in the oceans, which will have a hard time due to all the pollution killing them off. The cycle on earth will continue, probably with out most mammals, including us. So I'm sure the rain forests would be grateful for our CO2, if only we would stop burning them down (releasing more CO2) for a few plots of farmland that might be fertile for a few seasons.
I totally agree, and this should be well known by now. No scientific advancement in farming is going to change the way food distribution works.
Agriculture in most of the world has become disconnected from the land in a way that is not sustainable (excluding a few countries and cultures). The food industry can't expect to constantly take nutrients from the soil without putting them back naturally. The US destroyed the Great Plains in the 1930s, but has not learned it's lesson about harnessing the land for agriculture. There will always be famine, plague, etc., as long as there are living beings on this planet. If we were capable of controlling our own population, nature would not have to do it for us.
This is also why almost every living thing on earth ages and eventually dies. We have to contribute our nutrients back to the soil for the cycle to continue.
Hope they dont plan to leave that crap up there. Those mountains are pretty. Dont need a bunch of funny looking geeks and equipment fouling it up. Don't they have any buildings in poland tall enough to install that thing on?
Holy jesus flipping christ.
What is the #1 most important aspect of ballot box design? Security? Here is a ballot box with
A: No lock.
B: No hasp for a lock.
C: No one keeping an eye on it.
I might actually have a chance to be president in 2004.
4. No one loves it. C, Perl, Python, Smalltalk, and Lisp programmers love their languages. I've never heard anyone say that they loved Java.
What?
I love Java. There I said it. Of course script kiddies love their languages. What else do they know? I think Paul Graham should try building an enterprise app in java before hes starts spouting mostly foundles criticisms. Most of the people who have nothing good to say about Java know fsck all about it. This holds true for most people's views on languages/technology. Ignorance is bliss, write an article!
I totally agree. I have run across big hemp fields in Illinois, the ones I've seen are owned by the federal govt. Im guessing these are either left over fields that are not being harvested (left over from what, I dont know) or they are being used for energy research. (ok, I have no idea what they are used for) Hemp has a billion and a half uses, its suprising to see that it's mostly used in overpriced 'hippy' products. I'd like to see if I could run my 2 stroke motorcycle on hemp oil and methanol.
At $3 Million, it beats the pants off a cold fusion plant, which would cost between 5 and 7 Billion (if we could figure out how to get one working)
Cold fusion aside, how does this measure up to currently available methods:
Nuclear energy averages 0.4 euro cents/kWh, much the same as hydro, coal is over 4.0 cents (4.1-7.3), gas ranges 1.3-2.3 cents and only wind shows up better than nuclear, at 0.1-0.2 cents/kWh average.
(The Economics of Nuclear Power)
The article does not mention overall cost per kWh, nor does it say whether the plant will use the shells as biomass for gas production or if it will burn the shells directly. I think burning them would be more cost effective, the CO2 output would probably be roughly the same.
How abundant are macadamia nuts? I eat plenty of macadamia nuts and butters made from them, very nutritious. Good for athletes and people who need lots of fats/calories, but if you sit on your ass all day you probably want to avoid them.
...all americans considering an escape to Canada to reconsider. Don't do it please! Solve your problems at home, don't bring them to Canada! Don't make a mess of the territories with your pollution,overdevelopment,suburban sprawl,fear,hatred,ignorance,etc.. Moving to Canada will not help you. Try voting for people who will make some positive changes for once, slick texas oil barons do not belong in office!
The TDI volkswagens are getting better mileage than some of the hybrids, and they are pretty inexpensive. A 2002 Jetta TDI gets around 66 MPG on the highway. Plain diesel is easy to get and cheaper in some areas than gas/ethanol. I considered buying a used fleet truck that was fueld by CNG (Compressed Natural Gas). Propane fueled fleet vehicles are also available. Both are much cleaner than gas, but these are mostly big trucks (Ford F150-F250 size or Vans). I would not recommend buying used fleet vehicles (from rental or leasing companies, city depts, etc) unless you are a mechanic and have the time to rebuild/fix them. Used vehicles in general are a bad idea. Most or all of the hybrids available are running small gas engines with electronic assist. Coupling a gas engine to the drive train means the engine still has to be pretty large (over 1000cc) to deliver enough power. Current electronic assisted designs reduce harmful emissions, but ultimately still produce them to some degree. Ideally the engine would be as small as possible, and only drive a generator.The drive train would be handled by electric motors. I have not seen a production vehicle with this design, although there have been plenty of prototypes. More fully electric drive train vehicles will be available in the next 5-10 years, hopefully the big manufacturers will be moving towards fully electric vehicles as fuel cells and smaller generators become more feasible.
to find a practical use for this 'invention'. I think someone really needs to find something better to do with his time. Sensory deprivation+Mobile phone? Hang on a minute, I'm going to take this call in my sensory deprivation tank. What is an 'in depth' phone call? If I want to spend a lot of money to have an 'in depth conversation', I'll use a video phone.
I think this comes from the long line of ideas that starts with:
1. Anything
2. Mobile Phone + Anything
3. Profit!!!
