Full disclosure: I work for Google on Chrome. A Chrome build is truly a computational load to be reckoned with. Without the distributed build, a from-scratch build of Chrome will take at least 30 minutes on a Macbook Pro--maybe an hour(!). TBH I don't remember toughing out a full build without resorting to goma. Even on a hefty workstation, a full build is a go-for-lunch kind of interruption. It will absolutely own a…

Yes, we are doing this wrong! But we don't have any right options yet either. I think another way of thinking about this is that if we can't imagine a better system, then the field is so mature that it has become solved and completely boring. I think systems programming is still a field for which there are new and novel problems to solve, or at least better designs to implement.

I grew up on the Commodore 64 (1 Core, 1 hyper-thread :-), almost 1 MHz clock freq, almost 64 K usable RAM). The machine was usually pretty responsive, but when I typed too quickly in my word processor it sometimes got stuck and ate a few characters. I used to think: "If computers were only fast enough so I could type without interruption...". If you'd asked me back then for a top ten list what I wished computers cou…

I have almost the same background (Vic-20, if you thought programming was hard try having only 3.5k of RAM) and feel the same irritation...but I don't wonder why computers aren't faster, I wonder why operating systems and application is so utterly shit. I have a Moto X phone (not too old) and watching it slow down is almost comical. Sometimes I'll decide to close a few apps and hitting the selector button brings up s…

I think most of the shit is concentrated on a couple of notable platforms: Windows and Android. Outside of that space I've noticed less productivity hampering nightmare tools and OS features. Really I get perhaps one or two bits of stupid from Linux a year on the server-side, usually when integrating it with Windows ironically, and on the macOS/iOS front I haven't had a notable issue since I switched about a year ago.

Saw the headline and thought "must be Windows".

I'm not a Windows hater, but one of my long standing gripes about Windows is that it just seems to have terrible multitasking compared to OSX.

I'm sure there are reasons but it just seems utterly symbolic of Microsoft that they never managed to get Windows to multitask in a rock solid, smooth and reliable way like OSX.

Wasn't this one of the reasons why the Go project started at Google, not necessarily for Chrome, but because C++ project compile speeds were horrendous for some internal projects.

Not saying Chrome could and should just switch to Go, it definitely would not be the right fit! But it's interesting that these sorts of builds still occur and consume a lot of developer's time.

While the issue closing processes slowly is unique to Windows 10, I've found similar situations of not being able to control my OS on RHEL, Fedora, Ubuntu and MacOS.

At this point I genuinely believe latency will be the death of general purpose computing.

iOS and Android very rarely get out of control. Apple is already pushing iOS devices as laptop replacements. But we lose a lot on these devices with their locked down OSs and inability to install the software we want.

Uhm I have a 40-core machine with 256GB of ram at work and I can make it completely unresponsive without taxing either ram or the cpu to 100% - we have a certain computational load that just destroys the CPURam bandwidth, so cpu usage is about 30-40%, ram sits at 50%, and yet the computer is completely unresponsive. It's exactly the same on both Windows Server and Linux - we're just running into hardware limits.

The modules proposal for C++ has been around a long time. We need it now more than ever. Projects are getting bigger and the C++ culture is evolving from runtime polymorphism to compile time polymorphism. Text inclusion is just not good enough.

This is great work. I hope MS can improve Windows 10 by fixing this. I just added a new Win10 laptop with much better specs than my 3 year old rMBP, and I'm shocked by how much apparently random latency I experience with the UI in Windows 10 compared to the Mac. That's not to mention the issues of sloppier track pad (which constantly detects my left hand while I type) or the ungodly slow unzip (via 7z). If only Apple…

I mean the trackpad issue is generally down to the manufacturer and the drivers they provide, but I take your point otherwise.

A pro tip with 7z is to use the two pane interface to extract and not dragging files to Explorer. The latter option extracts the files to a temp directory before copying them whereas the former extracts directly to the destination.

The Windows file systems are pretty cruddy in general though so decompressing tonnes of small files in general will take longer than on OS X or Linux.
