I had a HP tablet with a wacom-integrated screen. It cost me around $1000 USD several years ago and suffered various problems: graphics crashes, overheating, and worst of all, a malfunctioning tablet. The vent fans were placed and designed such that if I didn't disable the tablet, my cursor would jump down to the lower-right corner where the vent was and constantly wiggle/click.

Needless to say, I wasn't impressed.

My second HP I bought about a year ago; I was the proud owner of a DV8t, one of the first i7 laptops. Not only did customer support lie to me (infinite glass screen, what?), but this laptop is badly-designed, too. The battery has been completely dead for several months now and I hadn't even owned the laptop for a year at that point.

The volume, wireless, and CD tray are all controlled from a touch-sensitive panel. The kicker? The panel often malfunctions, resulting in my sound going haywire, my CD tray popping out randomly, and worst of all, my wireless flipping on and off constantly.

To add insult to injury, I can't disable it from the device manager like I could the crappy wacom layer in my previous laptop.

So whatever the price difference between Apples and HPs, I'm sure they cover something other than just the numbers associated with the hardware. I'm certainly never buying another HP and I'll tell everyone I know about how terrible HP's machines have been to me whenever I have the chance.
It's even more disappointing for open source projects.
There is not clear answer for this. It depend of the quality of you product and availability of similar products on given market, product niche and other factors. That is why there are different kind of software and different developers are preferring one or another.

How man 'lost his penile spines'

This is how we were taught at Oxford. The only problem was, the unmotivated/disorganised students (like myself) often didn't do the reading/studying in our own time and so had to have these extremely painful tutorials one on one with the tutor.

Also, I remember when doing Economic Theory, I spent 40 hours reading/studying in a library per week and still couldn't get my head around some of the advanced math and game theory, and really wish I'd had a teacher to teach me those concepts before the tutorial where we'd go through the problems. It turns out I was lacking knowledge of some mathematical transformations that I hadn't been taught because I didn't specialise in double math when I was 16.

Nevertheless, I favour this form of teaching.
OTA got a lot better with 4.3. Home Sharing allows you access to you whole iTunes library wirelessly, including (supported) videos.

The downsides are that the iPad won’t sync and consequently your PC has to be always on to allow constant access.

Yes can be. My typical approach is to write down what I want to say in an as idiomatic way as I can. Then I go on to implement the notation that I have come up with.

The code I write is usually very high-level code. It can be written like an acceptance test or feature test. I essentially try to model the business domain of the software as cleanly as possible. I might refactor the code until I can express the domain clearly, with DRY etc.

Implementing all the bits of my DSL is often then the actual problem. Often I meet areas of the domain that are tricky because I have never solved such problems before. I think only my the third implementation of some idea can be something usable. So sometimes it takes a long time to get there! :)

This is only a problem in my personal projects because, well, the main goal is to advance my capabilities and thinking and finishing the project is secondary.

Why do people cheering for new web technologies like to spread FUD against Ruby/Rails?

From the article, Ruby developers are assholes, Rails doesn't scale (for an umpteen time) and Ruby has high barrier of entry compared to Javascript (I don't know what does this even mean).

Actually the success of ideologies is more closely linked to the success of its implementations than its merit. For instance, the success of monarchies for such a long period in history was based on their stability. Likewise, it could be argued that the resurgence of democracy was based on instability in the existing regimes, more than any greater merit in the ideology. If the Soviets had been more successful, I can guarantee we'd be saying how the merit of equality of income is why the Soviets were successful, but we'd be wrong, just as saying the merit of democracy is why the US was successful.

I disagree with you assertion on creativity in maths. Maths allows creativity and is very open ended. You can do things that are not required but are creative - leveraging identities and properties to vastly simplify a problem, reframing the problem to make it more tractable etc. And programming is very useful to learning maths. Any topic that requires some form of calculating to build familiarity will benefit greatly from playing by programming.

Consider complex numbers. You usually first meet them with imaginary numbers and polynomial equations. But they are extremely obtuse. But if you look at operations on them in terms of vectors, lateral extension of the reals to make the picture in terms of solvable polynomial equations complete, or in terms of polar coordinates, rotations, trigonometry, and e you start to get a fuller picture. But if you really want to get them you program a simple system (scaling and rotating triangles for example) that allows you to leverage all those properties. You build in the identities and operations. And then you experiment. Play with it. Play is vital to learning. With that, you get motivation and a fuller understanding than a mere that is just the way it is. With that deeper more intuitive understanding you are able to remember and internalize it better. Making the future topics easier but more importantly, developing the ability to draw connections rather than merely leaving each concept in isolation.

That is why maths is so hard. So much of it is completely divorced to how they were originated and completely unmotivated and magical. With no intuition future learning is further crippled, building apprehension via a negative feedback loop.

Now it feels like I'm not killing the database upon each request.
I think that ease to create libraries is the key here.

I should point that the existence of specific libraries can be seen as a library creation with zero effort. So heavy-library-weight Java can be seen as a very productive language, but only when you use already created libs.

The difference between languages shows when you're on your own, when there's no library or tool under your hand. When you cannot find a giant to stand on his shoulders.
Very interesting points. Though in a clarification (http://groups.google.com/group/comp.lang.lisp/msg/fde8853dad...), he wrote: "You said it yourself: it's the library: regexps and database connectivity in particular."

In my own perspective, "all else considered equal", things like macros, CLOS, dynamic variables and conditions system have enormous advantages over say what Python has. But this advantage can be overwhelmed by other factors, since industry programming is a very cooperative venture. (Not just cooperation with coworkers, but also people you've never met.)

I did say kind of working out, not working out the way it should (for some definition of should I think we mostly agree on). I'm just saying that automation has made it possible for homeless guys to have cell phones, when before they couldn't.

I'm not even floating a guess as to whether or not he'd be homeless if it not for that automation. That's a much larger and more complicated debate.

On the balance, I'm still betting that more automation makes better lives for more people, even if it seems to increase inequality in the short run.

I wait patiently for the day when mankind looks at himself in a collective mirror and says, "Know what?, everything's so good now that we don't need all of this inequality." I think this is an essential step in man becoming a semi-eternal space-faring species instead of one that just drives itself to extinction.

American banks are really terrible with this, and I just don't understand why.

I live in Sweden, but I get paid for work I do for a U.S. company. Both my employer and I have Bank of America accounts in the states, and my employer sending a wire to my BoA account takes longer to process than me sending a wire from my BoA account to my Swedish bank.

So it takes longer to send a wire WITHIN THE SAME BANK thank it does to send internationally halfway around the globe. There's really something truly deeply wrong with U.S. banking.

Meanwhile, here in Sweden, cheques don't exist and everyone uses wire transfers to pay each other, pay rent etc. They're always free, can be done online, take seconds within the same bank, and half a business day between banks. And this system has been in place for literally decades.
Does anybody else get a little question mark over their head whenever they read about the "novelty" of being able to use javascript on the server?

Certainly everybody must remember ASP, which let you write all your server-side code in Javascript way back in 1998. You can still do it today, even in ASP.NET MVC.

And just like Node, nobody ever really shared much rendering code between the client and the server using that technology either.
I think a lot of incorrect assumptions are being made.

What does being unemployed have to do with lack of qualification?

If people who are unemployed generally did happen to lack qualifications, why not judge them on their (lack of) qualifications?

"Second, the new people who join this pool are the newly unemployed, who are less likely to be well qualified."

Why would this be true?
It could be that you have trouble think about these concepts but come up with good solutions in the end. Know that you have these features how would it feel to go back to Java. Then you think something like ok I would implement this with a multimethod and then you can start look for a complicated and ugly designpattern do mimic something like a multimethod.

Unless you are engaging with your target market, this is probably not the most efficient marketing technique. I could see it working in some cases though (e.g. outside a competitors conference, where you know 90% of the people who pass will be interested in your startup).

Great write-up! Basically a person that was using more than 20 years of Lisp successfully and considered Lisp allowing higher productivity admits that there are now other languages that allows higher productivity than Lisp.

At the end when I read the comment:

> I think that if Lisp does not evolve it will die, and I
> don't want to see that happen. I still think Lisp is
> great. I also think it can be, and should be, improved.

I wonder what kind of improvements does the author have in his mind! If somebody knows please kindly enlighten me.

One Core i7 box with 8GB ram and a second database slave (for replication) with only 1GB of ram. I was running node.js, mongodb and redis all on the same box. I believe it could have handled a lot more, because it wasn't really breaking a sweat on CPU or memory usage, and my dataset was small enough to fit into memory.

Perhaps "scaled" was the wrong word, as I wasn't using multiple nodes horizontally, but you'd only have to add more database servers to scale as the load contribution of node.js was absolutely tiny.

If you were doing huge numbers you could probably also put a load balancer in front of a couple node.js application servers, each connecting to the same mongodb replica set (which you could easily scale by just throwing in more nodes). But if you're doing an app like this one, you couldn't use nginx as a load balancer because it won't proxy WebSockets.
Thanks for all the feedback everybody.

I'll post individual replies too a little later.

"function" will be gone soon enough - replaced (ok, augmented) in the next version of JS with "#" - so you'll be able to write: #(x) { x * x } instead of function(x){ return x * x; }

Why Everyone Is Talking About Node: The very smart guys at Joyent are packaging it and pitching it perfectly.

The mobile platform has been gaining steam and so real-time interaction is becoming more important. Joyent was smart enough to see this & find a way to put their current infrastructure (lots and lots of invested $$) right into the middle of this. Node is well packaged as a solution to this. Very smart.

No doubt Node is the right solution for a lot of problems. And the guys working on it are very smart. But personally, I think that Node and Erlang compare somewhat like Lisp and C. At least at this point...

The DRM doesn't make the decode harder. The files used less CPU/GPU power because they weren't as well compressed.

They probably weren't as well compressed because they're intended to work on the older iDevices too which couldn't handle something tuned specifically for the iPad or, even more so, the iPad2.
Thank you for this precious feedback. I'll think about this. :)
There's currently no standard/expectation to do this, so I doubt departing coders would spend the effort and would rather just move on.

I don't think the domains of coders and recruitment/hr would really overlap in that way, I can't imagine having to - as well as continue my current job, get ready for the move to the new company, knowledge transfer, etc - also try and recruit a replacement.
