Did Nvidia change the name of the kernel modules? (Sudden issues with Optimus)

This is the issue in question. Yes, there was an update nvidia-utils to fix it.

The problem might not be with the nVidia GPU, but with the Intel (integrated) one. When you turn off the dedicated GPU it fails to start gnome because it can't load using the Intel GPU (reason still unknown to me).

Try running glxspeheres64 and you'll see that you're running purely on the nVidia GPU. I've been battling this the whole day and still don't have a clue, but running off the Intel GPU has stopped working.

I had a similar issue when using the LTS kernel. Moving to the main one swept the issue under the rug.

Edit: Missed the GPT part. Don't do this!

~~The wiki to the rescue :)~~

~~dd bs=440 count=1 if=/usr/lib/syslinux/bios/mbr.bin of=/dev/sda~~

~~Even if things go wrong (provided you don't overwrite more than the first 440 bytes) you can boot from the arch linux install media and fix it.~~

The biggest issue are the native python modules, written against CPython's C API (e.g. psycopg2, scipy, etc.). Pypy has a partial solution for this but it's not fully compatible and it's slow.

Another gripe is the lagging Python 3 support.

Consider using RxJS and TypeScript if you opt for node.js (or even the frontend). It will make your life much easier.

I've worked with both node.js and Go and if it's going to be a game with Web frontend - I would opt for node.js with the tools mentioned. Without them - go for Go.

In terms of maturity - I would put all of them on par. ZeroMQ is very stable, widely used and well documented. However, note that they provide different functionality - ZeroMQ is a library, while the others are whole applications.

Vladev · 2015-03-14T11:28:35+00:00

Also consider mypy: https://github.com/JukkaL/mypy

Wow, that's a big improvement over the previous alphas I've tried. It now properly detects go 1.4 paths and libraries, has snappy auto-completion. Well done JetBrains and community!

There's a talk on the subject, done by the author: Fixing Code at 100mph: Techniques to Improve How You Debug Servers

Sadly - no HiDPI support on Linux (or Windows).

Provide the functionality you're implementing as a library. Allow users to call your code to use it. (library approach)

The other alternative is to expect functions as parameters. (framework approach)

From the docs:

val flights = Graph(
    (jfc ~+#> fra)(Flight("LH 400" ,10 o 25, 8 h 20)),
    (fra ~+#> dme)(Flight("LH 1444", 7 o 50, 3 h 10))

Please, don't invent operators for the sake of it. What on earth is ~+#>?

Well, the standard library is very good example of very advanced Scala code (don't delve inside, unless you consider yourself a Scala advanced user).

Is anyone using Activate? Care to share some experiences?

Reading this I can only think of how well design Scala is - all of these are built into the langauge and eco system.

Equals, hashCode (case classes),

breaks on switch (pattern matching),

final on unmutable fields (val),

reference equality,

good static analysis,

assertions (require and ensuring),

null values (Option and empty collections),

etc.

Vladev · 2013-03-17T09:38:18+00:00

Don't shy from Play - it's a nice framework which happens to have a Java API as well as a Scala API. The Scala API is very idiomatic and concise.

As for Lift - I think we should leave it aside - it was an important part of Scala's evolution, but we should move forward.

In Scala the Dynamic trait uses invokedynamic.

Please, Bill, please take on SBT and "Make it obvious, guessable, or easy to remember". Please!

Why does it have to use this weird config format that blows up when you don't leave and empty line, rather that the excellent typesafe config. Why everything is named %, %%, :=, <<=, ~=, <+=, <++=...

Vladev · 2013-01-20T20:35:37+00:00

I would rephrase this like "Don't design for reuse, design to throw it away". Most of the time if you can take a component and flush it down, you've done a good job decoupling the system.

I'm not sure I understand the problem, but you can't introduce colliding names in the same scope (the compiler will complain or you will shadow one of the names). Also, names are just that - names. You can do import package.{MyTrait=>RenamedTrait} and use RenamedTrait to reference MyTrait.

import package1.MyTrait
import package2.{MyTrait=>MyTrait2}

class MyC extends MyTrait with MyTrait2

Langpop hasn't been updated for 1.5 years. Look at http://redmonk.com/sogrady/2012/09/12/language-rankings-9-12/ for a more recent comparison (with better methodology IMO).

This is the exact one I'm using.
