LinkedIn is 99% Java but 100% Mac Eishay Smith 6/17/08 11:11 PM
Just to complete the picture, the rest is using C++, RoR, and Groovy/Grails.
Actually we have one team, which is RoR top to bottom, and another team doing a full product in Grails.
Nevertheless, almost all of the core business logic is using a Java on Spring/Jetty/Tomcat stack.

The 100% Mac is the development environment of all of the engineers in LinkedIn (i.e. desktops and laptops).
Keep the Apple talk in the podcast :-)

Though I respect Joel Spolsky, I strongly disagree to the stuff he said about Macs in his StackOverflow podcast.
The Macs are definitely not just luxury, they are a superior development machines.
Most of the engineers which come to work here are using Macs for the first time as java workstations, and you can hear this statement again and again.

Join the LinkedIn posse group, almost 300 members and 100% java :-)

Care to qualify that subjective marketing statement a little... In
what sense are they superior? What can you do on a Mac that you can
not do on no-nonsence Ubuntu box? I find it's usually the languages
and the tools rather than the machine which makes a difference during
development.

Casper,

I have to agree with Eishay that Macs (OSX) are superior codestations.
Although I've only been actually _working_ as a developer for about 7 years, I have atleast 12 years experience
of developing on windows (C/C++/Java),

I made the permanent switch to OSX/MacBook Pro a couple of months ago and I would _never_ go back.

Straight out of the box it just much more competent than Windows (2k/Xp/Vista), and when you've got your dev-environment set-up
you're just ready to actually get some work done.

Compared to Ubuntu it's more polished (I've used Ubuntu 6 and 7) and the features work OOTB instead of having to fight with drivers and utilities
(never got the smartcard-reader on my last laptop to work from Ubuntu)

And from a user-perspective, things are noticably more inuitive on OSX than on Windows/Ubuntu.

But ultimately its about having the possibility to use the tools that you are most productive with, and that you get to enjoy your work.

Cheers,

Well, as of my last attempt at Ubuntu about 18 months ago (before I
switched to apple)

1. My wireless networking works flawlessly (Took a competent Linux
admin (not me) about 1/2 a day to get it working (and even then, not
all the time)
2. My power/thermal control works flawlessly (Poor battery life +
overheating)
3. Auto-updates don't kill my windowing env (One poisonous auto-update
killed my machine for a day)
4. My wireless 3G broadband adapter 'just works'

Everybody's milage varies -  besides writing code I also enjoy editing
home videos of my son, syncing my ipod, managing my family photos,
playing around in photoshop etc etc - Apple is a platform that gives
me all of that in an efficient, reliable and powerful platform - and I
don't have to spend hours stuffing around to get it working.

Also, I think my black MacBook looks kinda sexy :)

Casper: Hardware considerations, and hardware/os integration issues.

Close your notebook and 'just' have it go to sleep properly, no matter
what you were doing. A high quality keyboard. Two-finger scrolling
trough code. The ability to buy something in a store or mail order it,
open it up, install just the exact tools you need, and get going,
without having to customize a truckload.

Ubuntu is sneaking closer every day though, and at this point the
difference is marginal, especially if you run ubuntu on apple
hardware. It's a real shame other notebook manufacturers are producing
such turds. Apple is getting a massive free ride simply because no one
to date even makes a notebook with a halfway decent keyboard.
Possibly, part of the mac/apple hype is simply a grassroots effort to
convince other notebook manufacturers that going for a nice list of
specs plus a low price is just not how you should be doing business
anymore. You can't put 'feel of the keyboard' or 'proper software/
hardware integration' and 'no need to reinstall an OS to remove all
the crap we've foisted on it' in the spec list, but those are all far
more important than 0.2 more Ghz, or 40GB more on the hard drive.
Re: LinkedIn is 99% Java but 100% Mac Ben Schulz 6/18/08 6:25 AM
I own a Dell laptop and the only thing missing from your list is the
two finger scrolling. Not sure if it could handle it (hardware wise),
but I don't really need it anyways -- I mean 99%+ of the time I have a
mouse attached anyways.

PS: In my experience setting up Ubuntu is a breeze.

With kind regards

@Casper: These are good questions, which I don't have a definite answer to.
The language indeed maters a lot, its the material you do your product with.
The tools (IDE, OS, Shell ...) are probably more of a subject to individual taste.

Quality of a tool is something that is hard to measure. You can take two sets of tools that do the same functions with the same empiric parameters but one is clearly better then the other. The proof is simple, go to tour favorite construction tools shop and see the price and perceived quality difference for tools that have the same power and size. Last time I did that and asked the expert why one is better, he told me that its just is :-)

We can start a nice philosophical discussion here, but at the end I think you must try it for yourself and only then you'll understand. The answer is in the small details that eventually do matter. I'm not smart enough to say why Mac is better (maybe quicksilver, iTerm, slick integration between applications, FreeBSD core...), but I belive that eventually it is.

I want through the Windows, Ubuntu and Mac, used each for several years.
I would argue that most the people with similar experience would have similar conclusions.

Re: LinkedIn is 99% Java but 100% Mac Casper Bang 6/18/08 12:22 PM
Thanks for clarifying Eishay. Clearly Apple is very good at picking
quality components and pushing new aesthetic boundaries, and that's
good for all of us as consumers. What scares me is the lock down
issues and "milk-the-cow" policies. Colleagues with Apple computers
have to pay twice as much for a RAM upgrade, they can't just plug in
arbitrary hardware and for 1½ year were unable to run some of our
software because it's written for Java 6.

So while I am sure I could be an Apple fan boy too, I am just not sure
I am ready to trade in my freedom. If I cared only about superior
development platform, I would've stayed on Windows and had my fun in a
language containing all the features which is cause for so much
controversy and confusion in Java these days.

They were unable to buy a DDR2 SODIMM?
I can offer to instruct them at a nominal fee.... ;)

Same experience (Windows until 2003, Ubuntu until May 2008, Mac Book since JavaOne :).
Same conclusion: I really love the Mac experience, but I miss my Ubuntu freedom.
I hope, that the big increase in developers using Mac will generate more and more free and cool application I missing: meld (DiffMerge so so), better term, scp in Finder (Fugu way below Unix), and more.

But, the multi-touch, the screen and second screen, the UI, I'm so enjoying it!!!--

Ditto the sentiment. I don't purchase the RAM upgrade direct from
Apple, but that doesn't keep me from getting it from any other
reputable vendor. Seems like its the same RAM as in and other Intel
system.

When I bought my macbook pro a few months ago I skipped Apple's $400 4
gig upgrade and bought with the mininum 2 gig.  Then I ordered 4 gig
from newegg for $105.  Works fine.  It's just an intel motherboard in
there.....
Re: [The Java Posse] Re: LinkedIn is 99% Java but 100% Mac Peter Becker 6/18/08 3:29 PM
I got a Dell, too -- and I'm happy with the keyboard, the extra DPIs
on the screen and the way Ubuntu configured everything in there,
including the right resolution for the screen, the sound, the WLAN,
the SD-card reader, Bluetooth you name it (never tried the modem,
though). Both suspend and hibernate work without any problem. And
that's on hardware that was not designed to run Linux (it's 3 years
old now, and I don't think Dell was into Linux back then). To install
something that's not there out of the box, I kick of Adept, type the
name in and tick the program in the result list.

The one thing that still annoys the hell out of me is dual-head
support. While I tend to get configurations I want, changing them
involves restoring my backups of the xorg.conf file -- configuring it
using the UI is just too fiddly and doesn't always work. And you have
to restart X to change, which is a pain even with KDE's excellent
session management.

But while I believe I understand what the Apple crowd is talking
about, my pain is just not big enough to lose my freedom. Of course
there is the option to run Linux on Apple hardware, which sounds
enticing :-)

Re: [The Java Posse] Re: LinkedIn is 99% Java but 100% Mac Frederic Simon 6/18/08 3:40 PM
First thing I tried (just in case) to put Ubuntu on my Mac book pro, and not very successful... So, I'll wait.
The dual head was a big pain for me too. I managed to have a really good conf that worked most of time (with xrandr to play with the resolution) but the X reboot was a pain.
Now with 8.04, ATI driver (on my T600p Lenovo) are not even supported anymore, and I can't develop Stellarium... So, I'm happy to check JOGL bugs on Mac and finally have a great version of Stellarium for Mac, but rigth now :( No sky...
Frankly, I really love this feeling that OS competition is not dead, really exiting time.
On the other hand I can't ignore Windows deployment and Sun buying Virtual Box and making it full for Mac is solving it all: Ubuntu Hardy and Windows XP on top of my Mac OSX...
Re: [The Java Posse] Re: LinkedIn is 99% Java but 100% Mac Peter Becker 6/18/08 4:50 PM
Somehow many of the Linux ditros have move to support only recent
hardware well -- which is not that different from other platforms,
really, but the old scheme of taking an old box and putting a recent
Linux on it doesn't necessarily work anymore :-(

Hardware support is much better if you buy hardware that is explicitly
supporting a particular OS and I think that is one of the major
advantages of Apple -- they deliberately restrict themselves to a
small collection of hardware and they are happy to stop support for
old hardware in newer versions of MacOS. Which is really fair enough,
but I don't think it is fair to claim Linux has lots of problems with
hardware that MacOS hasn't -- any comparison of that type should be
made on components that were chosen for Linux use, not the old box dug
out of the closet.

Which dell is that, Ben? I've never met a dell with a proper keyboard
to date. Their batterys have so far always crapped out on me after
less than a year, too. I also hope they've done something about the
power bricks. Last time I checked they were half the size of the
notebook. Dells are kinda hard to go admire in a store, especially
here in europe, and these days I don't know anyone that buys them, so
I'm a bit out of the loop. If dell is finally catching up, that'd be
an excellent sign - I get antsy knowing there's only one hardware
manufacturer out there that makes something I can work on. Single
point of failures are bad :)

Casper: ... then your friends are idiots. It's a well known thing that
apple 'milks' those who couldn't be bothered to do their own memory
upgrades. Just buy 2x2GB SO-DIMMS for like 70 bucks, and install it
yourself. Same story, to a lesser extent, for the hard drive (that's
only for the macbook, all other apple notebooks don't have a removable
HDD IIRC). Also, since when do other notebooks offer extension
capabilities? Macbooks have USB, Firewire, and the pros have this
expresscard thingie. Aside from the aging PCMCIA that's about as far
as notebook upgrades usually go. The java6 thing was bloody annoying
but fortunately all around java hero landon fuller, along with sun's
wise decision to open source java, means that'll never happen again.
Re: LinkedIn is 99% Java but 100% Mac Ben Schulz 6/18/08 7:01 PM
It's a Latitude D820. It's pretty much exactly two years old and I get
a solid 4 hours out of the battery.

I'm not sure what you are looking for in a keyboard, so I couldn't say
it has a "proper one". Then again the Mac keyboards aren't
ergonomically pleasing either; for a laptop that's obviously okay, but
I'm sure you don't do much of your coding on the road, and since we're
looking for the "superior development platform"...

I agree that the devil is in the details, but if there is one thing
that I am sure of it is that sooner or later Linux is going to kick
ass. I'm betting on sooner.

With kind regards

I've got an Inspiron 6000 from about 3 years ago and I'm still pretty
happy with the keyboard -- it sure beats the $5 crap you find on most
business desktops. It's not perfect, but mind you: the only keyboard I
ever really liked was the very first edition of the Microsoft Natural
Keyboard. But I guess keyboards are a very personal thing and depend
on ones taste a lot.

The fact that you can't test a Dell before buying is a bit of a
problem, though. Fortunately down here you find some stalls in the
hallways of larger malls now.

I hope I did not sound too much like an Apple fan boy; I really try to be just a practical engineer. Hey I actually don't have an iPhone (well, not yet at least...).

I might be detached from the real world here in the valley, but I don't feel like the price and Java6 are limiting that much.
We have MacPro 8way/cpu and 12gig/ram with two 23'' cinema displays for engineers here (and macboks).
Is it expensive? Sure!
Do I care? Not really – my bosses should care. For some reason they concluded that better tools pays up over the long run. I believe they're right; you invest so much money in those software engineers so you might as well max out their productivity.

About java6, as I see it, the key improvement is performance. As Mac is the development environment, it is not for deployment. In the production machines may have the latest and greatest JVMs.
If we get to the point of being crippled by the JVM version we can always downgrade to another OS - no problem since the code is Java :-)
The problem with moving to another OS is that we loose the freedom of using some great Mac applications (see QuickSilver), where on Mac you have the freedom to use most of the good apps available on windows/*nix (IDEA, Eclipse, Firefox, OpenOffice ....).
