Not intending to start a flamewar with VM/Intepreter implementations, BUT I have to agree with the article.

When I was evaluating on platforms for a rewrite of xp-dev.com, I did seriously consider using RoR with JRuby, but there was some parts missing here and there (including some bugs) that it was just not worth the risk for the scale of the project.

I ended up going back to a Java web framework, thinking, I'll keep a close eye on JRuby and see if it can be used in future projects.

The JVM is an excellent VM - things like having the ability to set heap sizes, JMX and all the readily available sugar that comes from it is well worth trying to support as many languages into it, and for that reason, Ruby needs the JVM. Re-implementing things like JIT, GC is just not worth the trouble. Ruby hackers can actually focus on real, hard productive features and essential bug fixes which would be a better use of their precious time.

* JVM here refers to Sun's JVM implementation, not the spec. JRockit is pretty good as well.
Here's a version of strace for Windows: http://www.intellectualheaven.com/default.asp?BH=projects...

I've hacked it to print the actual file names on CreateFile() calls, but it's failing because it doesn't recurse and trace sub-processes. It should be theoretically possible by hooking CreateProcess(), but it's probably hard.
I don't believe there is any credible evidence (i.e., studies not done by organizational consultants pimping their tests) that Myers-Briggs tests predict much of anything. I don't think they predict whether a person will be good at a particular job any more than asking that persion "will you be good at this job" does.

Sometimes people need a vocabulary to talk about people with. I think that's why some people get into the Zodiac stuff, it just gives you a way to talk about personality traits. You could also use Tolkienian races -- "Joe is a imperious, perfectionist Elf when it comes to writing code" or etc. Regardless of what group of names you pick, usually the people who are very successful do very well in one area, say introversion / introspection or something, and can force themselves to do decently in the "opposite" area. Kind of like how some of the important characters in Tolkien were half-breeds.

The appendix of "The Organization Man" by William Whyte contains a guide to "cheating" on Myers-Briggs type tests, to get a score appealing to a large organization. I highly recommend reading the whole book but especially the cheating appendix before interviewing at a corporate place.
A higher percentage of screen (whether on laptops or separate monitors) are

Why would anyone want to dislike a company? Why would anyone want to dislike anything at all?
Give the option for both. If that confuses or scares users too much, have one as the default and the other as an add-on that users who really want it will have to download.

As of right now, ff users have to settle for the tabs-on-bottom style unless they want to settle for a combination of 5 add-ons, which - i'll assume - significantly increases memory usage.

I believe this is very much related to what I said about the "bubble lifestyle" here: http://news.ycombinator.com/item?id=652562

Perhaps it goes without saying that living the bubble lifestyle entails focusing on the short term at the expense of the long term. As Andrew says:

As an entrepreneur, I can’t help but look at the short-term choices that get made in an environment like this without some degree of disappointment. There are many brilliant people who could be trying to make the world for the better and really create long-term value, but instead they are engaged in...

I share Andrew's disappointment, but from the rest of his post, it seems we probably disagree on the cause(s). Part of my explanation is in the post I linked to above.

"If we can leverage JRuby to grab 1-2% of the Java market, we'll double the size of the Ruby community" - that's pretty incredible.

IMHO it could be smart of the community to put some effort into getting JRuby on Rails working smoothly on Google App Engine. GAE makes deployment and scaling, traditionally RoR's weaker points (though much improved since Passenger) almost a non-issue.
I've ended up on the opposite side of the spectrum - back when I was working as a developer in an office, I used to write something at least once a day and that kept my handwriting in check.

However, ever since I started working from home, I just type everything. I was even nervous signing a credit card slip the other day as the merchant's chip and pin terminal was broken.

I do envy your good habit of using pen and paper for journal/note-taking!
scala is a better language than ruby anyways. if you rubyists want to promote your language you had better get serious about staking out your turf on the jvm, which is (i'm sorry to say) the only non-microsoft place where the enterprise can find serious concurrency and gc.

the various full stack rubies are cute, but if i don't have grown up concurrency then i'm not interested.

2 weeks ago I would have said "coffee" - used to drink about 6-8 cups a day between 3 am and 7 pm (working hours). Over the past 2 weeks I've switched over to mostly water and 2 cups of coffee per day at most and its unbelievably fantastic.

Water for me has to be room temperature though. Not sure why.

It's funny how helpful and nice T-Mobile was when I brought in my unlocked iPhone. They got me setup on a pay-as-you-go plan in no time.

After 2 years of being a loyal customer, AT&T shut my account off for "excessive use of partner coverage" ... even after repeated begging and pleading, they wouldn't restore my service.

Thanks. That's useful input! :)
The rules are pretty simple. It works everywhere, except in a function call, where = is used for named parameters, not creating new variables.
I wonder if there would be a good system for showing two stories are related

I believe that is called a hyperlink, as here.

http://news.ycombinator.com/item?id=726421

Hyperlinks generalize to showing that three or more stories are related, and allow annotations (by accompanying text) to show the nature of the relationship. Here, I can make clear that the thread to which I post this reply links out to an article that refutes the article linked out to in the link

http://news.ycombinator.com/item?id=726421

I have just provided to another HN discussion thread.

Hypertext is wonderful.
I dropped out of MIT due to money -- I'd received no financial aid and no other assistance, and couldn't get loans (since I was under 18); I tried working and consulting to pay, but ended up about $50k behind in "late tuition payments". I had turned down full honors scholarships to other schools, mainly because I really wanted to go to MIT.

Luckily this was 1998 and I left to go start a crypto ecash startup in the Caribbean, first of several startups. I think 1 semester in a top school, then dropping out to do startups, might be a better education than enduring 4 years without really doing anything special. That said, I wish I had been able to complete a degree; I am 30 now and sometimes think about ether going back full-time to MIT, or doing a UK MBA, or taking classes at another school and then either finishing there or returning to MIT.

In retrospect, ROTC might have been the best option, but there were a few specific reasons I didn't do it at the time.
A girlfriend bought me a fuzzy logic rice cooker (about $150, I think) a few years back. Best kitchen device ever.

Single-use kitchen products are silly, not to mention space-inefficient. Even if it makes oatmeal and rice, that's basically just a bunch of starch. Might as well just eat Ramen.

One can find a nice set of sturdy department-store quality cookware (with lids!) at a discount retailer (like Ross or Marshalls). They'll go much further in ensuring consumption of the variety of nutritional foods. Basics one can get for about $60 for all three: a boiling water pot for the stuff to be cooked in bulk, a saucepan (cause bland rice is boring) and wok-shaped skillet. They fit neatly inside each other space-wise, as well.

My secret to rice cooking: add a wee bit of vegetable or other oil (I also like to add a bit of cayenne pepper to the oil sometimes) in the skillet, and let it warm, but not over super hot temp. Then add the rice, and kind of "sautee" it for a little while, but keep the rice moving to make sure it doesn't burn. You really just need coat it a little little bit, to prevent it from going mushy and therefore cannot coat the bottom of the pan with the black mush that happens when the rice is added to the water. After adding the water and bringing it up to a boil, you can turn it down to the lowest temp on your stove, cover it, and let it cook for the rest of the time on the package.

I guess the one prevailing great thing about the fancier rice cookers it that they beep when they're done. So I guess if you use my method, don't forget to set a timer.
Yeah, FUCK professors! Just because they've spent an inordinate amount of time becoming experts in their field, including extensive vetting by their renowned colleagues, they just expect things like "jobs" or "credit." Who the fuck do they think they are?!

Even if EY can't keep them for more than another year, the salaries would allow them to keep working on their pet project for that long and push out a few "good enough" features just to keep the community happy. After that they can jump ship again and start their own JRuby consulting firm; all it takes is just one or two big clients that need support. The fact that they're currently employed to maintain JRuby would certainly guarantee big firms taking notice and consider using it ("hey, there is actually someone we can pay for support", etc.)
Most younger R programmers use _ for multiword names. Using . is generally not recommended as it is more commonly used to identify generic methods in the S3 object system.
Perhaps I will try that.

After the last major redesign, I found and continue find the enhanced emphasis on graphics -- e.g. larger profile thumbnails and whatnot -- distracting; I find it isn't as easy to quickly scan the page.

I've idly thought a time or two of using a filter to block the thumbnail images. This thread made me think to try simply blocking all images. Result: A page much easier for me to scan. And while the quiz results are still there, their annoying graphics are not.

Mind you, I like seeing my friends published photos, and sometimes a friendly profile thumbnail cheers me up. But the rest is mostly visual busy-ness that slows me down.

As for the personal images in ad's, there's a way to effectively opt out of that, now. I believe it was mentioned here on HN. In Facebook, it's under

50% of the hover window always dedicated to advertisements? No thanks.
Right, but there's no way to tell img.4chan.org from some random blog. Sure you can look at whois, but if you do this in this case, you get NetAssist, which seems to be the hosting company. It's likely they never forwarded the messages to the owners of the server.

Unless you expect the DC techs to nmap servers to find services to identify them. Would you know the IP to HN if it popped up in a firewall log?
My drinking habits sure do tell a lot about me, huh?

I kind of have trouble with my sleep. I sleep wonderfully (8-17 hours; yes, 17, not very often though, on average 11), but I think (or thought?) I have mild free-running sleep disorder, where I go to bed later and later each day (if I didn't manually control it, I'd have a full 24 hour cycle over the course of a few weeks). But I've never thought about pop being the cause. I'll try and ditch it, see if it makes a difference!
One of the big selling features of the Android SDK, for me, was the ability to completely replace any aspect of the system including the dialer, contacts, music, etc.

What we Want from the Apple Tablet
So very true. Polygraphs measure physical reactions that can be easily controlled, and misconstrued. Many people will react in such a way that could be read as a lie by simply being shocked or embarrassed in the question asked. Not to mention being nervous can give many of the reactions too.

The results of polygraph testing aren't even admissible in many courts, and the National Academy of Sciences found that they're unreliable, unscientific, and biased.

Despite all this, so many people think they're still a bullet proof method of lie detection. I have heard of a many people who have had false positives on polygraph tests, and have had their life ruined because of it.
In fact, most of the carriers here are fucked up.

Yahoo needs to try something new and different. No amount of rearranging tabs & links or switching fonts is going to make a bit of difference in the long run.
Assuming that placement on the front page is determined by points/age, allow users to set the weight of age. If I were to set the weight to .3, I would end up with the "/best" page. Users might set this based on how often they visit, via a textbox in the upper-right of the news page.

I'm honestly really thrilled with all the choices on the JVM; not just JRuby, but Java, Clojure, Groovy, Scala, Fan... and they all play together incredibly nicely. It's an amazing productivity boost to be able to use a dynamic language (like Ruby or Groovy) to handle all the business logic and glue code, while at the same time being able to take advantage of the speed of pure Java when you need it.

OK - but why is that desirable?

Yes, you will not get to live forever, but it also means that human beings are healthier for having had so much variety of experience.

What do you mean to say human beings are healthier?

I'd hope the species as a whole is benefitting a lot from the 150,000 people who die every day. How is the species benefitting (in ways that could not happen without mass unplanned death)?

Which is exactly what I meant when I said this:

Prudent use of Discount Coupons
One of the interesting things about discount coupons like Dell coupon, Expedia coupon, Buy.com coupon, Macys coupon, Sears coupon, Sony coupon, Apple coupon, Delias coupon, Forzieri coupon, HP coupon, Smith Noble coupon, Officemax coupon is that they can save us money as well as waste money. Are you wondering how can discount coupons make us waste money? You already know it and as soon as it is mentioned you will know that it is true at times discount coupons make us waste money.
virtual workspaces, no doubt.
What interesting timing as just this morning I was listening to a little news bit on NPR where they talked about research into the nutritional impact of various cooking methods (and of _not_ cooking food a la raw food enthusiasts.) The research has shown that you must cook your food to get the full nutritional value of beta carotenoids, lycopenes and a couple of other important nutrients. The cooking method which preserves all nutrients best is the microwave. It is equivalent to or better than other cooking methods for every nutrient they tested does not have any impact on the water-soluable nutrients.

Great article. I had heard missionary and mercenary CEO's mentioned, but hadn't seen anything about it yet.

In the video he says (paraphrased), "if you can't see yourself doing this your whole life, don't do it", if you're a missionary CEO. So the thought that came to my mind is - what if you're on a mission and your start-up solidly aligns with it, but one start-up might not handle your entire mission? If a start-up is a launching pad, are you a missionary, mercenary, or combination of the two?

Yes that puzzled me too. I guess Engine Yard can see some business value - maybe offering support for people that have already chosen JRuby for their projects or perhaps they will feel more able to support Java in their services.
If you buy it here without 3g support it costs 896 dls (only the iphone and a phone line). If you buy it with a 3g plan the cheapest plan costs 46 dls per month and an extra cost for the iphone (597).

Of course the service is bad, we don't have all the nice features like in USA or Europe (because of the old service provided).

So here in Mexico the problem is not Apple, AT&T, etc, but the carrier (Telcel). The Iphone is useless here, excepto as phone and mp3 player, and sometimes for bad surfing.
