Lessons learned in development and technology
After upgrading to 16.10, when I would resume from sleep my xps 13 would reconnect to my network but not have any DNS (it had a connection, but couldn’t navigate to sites by name, IP addresses worked). I was able to issue a sudo systemctl restart network-manager And this generally brought the network back online …
November 6, 2016Summary If you are using linux behind a company proxy/firewall odds are you have issues with accessing ssl resources (i.e. https). The company likely has their own Certificate Authority (CA) that issues private certificates. These certificates are not issued from ‘trusted’ authorities (i.e. verisign et al) and therefore the browser does not ‘trust’ them and …
May 7, 2016UPDATE 5/11/2016 – The flicker is apparently Chrome only and has a report to Google. If you use firefox you won’t see this screen flickering. You can also run Chrome via “google-chrome –disable-gpu-driver-bug-workarounds –enable-native-gpu-memory-buffers” and the flickering will stop. You can also edit the desktop file which will allow you to launch the app as you would normally …
April 23, 2016Summary I have been DYING to try Mir every since it was announced. Moving X forward, new libinput integrated for a solid touchpad experience .. the entire thing is very exciting. Since I’m lucky enough to have a System76 Galago Ultrapro AND Dell XPS 13 9350 I figured I’d try to install 16.04beta1 (ubuntu/unity) on …
February 27, 2016Summary If you’ve ever messed with UI programming that utilized the ‘hash’ URL technique for invoking UI actions, it’s time to go html5 native! This blog post will describe how to setup an apache docker container with the pieces enabled for URL Rewriting. This allows html5 ‘pushState’ to be utilized instead of hash operations. Some …
February 14, 2016The laptop has been running well on 4.4-rc7 but the new 4.4.0 kernel came out and I’d rather be on the newest officially released kernel (until Dell releases the official XPS 13 with an official kernel that is). So I grabbed the newest kernel and installed it by running cd /tmp wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400_4.4.0-040400.201601101930_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-image-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb …
January 22, 2016Add this to your ~/.bash_rc if [ -f /usr/lib/git-core/git-sh-prompt ] then source /usr/lib/git-core/git-sh-prompt export PS1='[\u@\h\w$(__git_ps1 " (%s)")]\$ ‘ fi Then watch your shell go from this [jim@galago~/projects/HIIT]$ to this [jim@galago~/projects/HIIT (add-docker)]$ Notice the branch name (add-docker) in the prompt? You’ll also have command completion for git commands (i.e. git a<tab><tab> will show) [jim@galago~/projects/HIIT (add-docker)]$ git …
December 29, 2015My previous post on this topic talked about a mechanism for installing a custom 4.3 kernel that has the broadcom wireless drivers built in. I found a cleaner way to run a 4.4rc7 kernel from ubuntu that supports wifi, has no audio sizzle/static, and seems to run everything wonderfully. It’s as simple as the following …
December 29, 2015The Present So my first post on this blog was about the Dell XPS 9333 compared to the System76 Galago UltraPro – I bought the System76 and don’t regret it at all. It’s a beast. The GPU is VERY strong (not as good as a discrete GPU but much better than the normal laptop level …
December 28, 2015Why is there an issue? One area that X has really fallen down on is the driver for the touchpad. It’s passable if you tweak it .. but why settle for passable? Shouldn’t the open source world have a KILLER touchpad implementation ala OSX? For a very brief time I owned a Macbook Air and …
