Instead of XPSs, we bought Precisions 15 5000 at work [1]. They are basically XPS 15, (virtually indistinguishable apart for the engraving on the bottom), but you can spec them to bits (you can even get a Xeon processor if you want,have them with no OS / Ubuntu). All of us are reasonably happy with them.

Another Precision user chiming in. I got one at work and after I updated the Intel video driver, I've had no complaints.

These look very good, thanks for the recommendation.

I should have probably added that I run Arch on my personal machine (XPS15, infinity display).

The arch wiki is absolutely great, but it doesn't have much/any info for some (newer) laptops (e.g. XPS15 9550, X1 Carbon 4th gen..)

That does sound very very nice.

How's the screen like? Do you see pixels when reading text/code? If my calculations are correct, the Dell Chromebook has 169PPI, while the MBP 13 has a 227 PPI display.

I don't see pixels, but it probably doesn't mean you won't see it. It is a very nice screen, however, there might be bleedings - less or more depending on your luck. My girlfriend has a Macbook Air 11 inches and the Dell screen is another league. It is matte too, so it has different characteristics compared to the Macbook pro, and what is better depends on your taste, but I like matte screens better.

About DPI I would love to have the MBP screen, so I can do the 2x DPI mode, however, ~1.5x scaling for 1920x1080 is not bad at all. KDE scales odd DPIs really well, so I don't have a problem with it generally speaking. After you set the DPI on Control Panel/System settings, everything scales seamlessly. I have yet to find something that makes me frustrated in terms of app scaling.

I should probably point out that my personal machine is a Dell XPS 15 (infinity display), on which I run Arch.

Almost everything works, but I'm having trouble with a couple of things:

Graphics. It has switchable intel/nvidia but I get a better performance out of the intel chip still. Battery life is about 2.5/3 hours. I haven't tested bluetooth. The fan sometimes comes up without any apparent reason. Palm detection and gestures don't work, but the trackpad is ok otherwise

The display is gorgeous, the machine is a beast and I'm very happy with it otherwise.

Have you ever seen the screen on the new XPS 15? It's a 4k. It is absolutely gorgeous.

The XPS 13 (which OP refers to) has a 4K screen as well.

I agree, it's a gorgeous screen.

we've built it in 48 hours and there was no time for that. But it was in the plans..

Yup, what codexon said.

Since this was for clojurecup, we have decided to remove all references to Scala. :P

On a more serious note, we've only indexed ~25 courses and probably the ones you refer to weren't among them; if you have a particular course in mind, tell me, I'll fire up the scraper..

Functional Programming Principles in Scala and Principles of Reactive Programming are hits I would expect.

Cool, I'll add them tonight.

Am I the only one here who thinks that maybe a petition asking Mozilla to pressure Eich to step down may be a better solution to this?

I seems that all the years of contributions and sacrifices by the community to build a great product, fight for a better internet and all that mozilla has stood for could be very rapidly undone if we continue portraying it as a homophobic institution. All of this good, from so many people, undone for the views of one man.

Say we are successful with this, Firefox goes out of the picture. Mozilla is dead. Would that be something to aspire for? I'm creeped out by the state of the internet as it is already, mozilla seems like the last company that truly cares. Who would fight for keeping the internet open then? Google?

Let's direct the criticism to the man for his beliefs, lets let know mozilla that their choice is not cool and we won't accept it. Let's not bring the whole thing down with it please.

Even better, let's not criticise someone for their beliefs about marriage. "Marriage" is not a person, or natural thing. If people think it should be limited then so be it.

Legal rights on the other hand, that's another matter. The problem is that people lump marriage and legal rights in the same boat, then don't hesitate to unleash hell on anyone who thinks marriage should remain traditional and.. "YOU"RE ANTI-GAY"... wait, what? I just think marriage is between a man and... "YOU'RE HOMOPHOBIC".

I'm sick of it. A lot of people are sick of hearing about gay marriage. Sure, let's recognise civil unions and the rights there, but leave marriage out of it.

uh oh . someone is scared...
