Fallout 4 Improve Framerate

Running Fallout 4 at 50FPS on a low end graphic card My self built development rig (currently pumping out OrchestraCMS/Salesforce sites) does not have a discrete 3d video card, but instead it has a low end Radeon HD 6530D built-in as part of the AMD A6-3650 CPU. Clearly it is a system not designed to handle latest games, but once in a while I like to indulge and so this time I tried playing Fallout 4... Even at all the lowest resolution and settings I was only able to squeeze about 16 frames per second (FPS) --- I rather watch paint dry. Overclocking the rig front side bus (FSB) 35% from 100MHz to 135MHz, that is CPU from 2600MHz to 3150MHz and DDR3 memory from 1333MHz to 1799MhZ (the F1A75-V PRO motherboard is fantastic for overclockability, just ensure to run the latest BIOS which allowed me to push it this far) things improved by 8 frames to 24FPS. Better but that's when there isn't anything existing happening on the screen so still unplayable. Changing resolution in `Fa…

Speed up Saleforce Development

Fast Salesforce `staticresrouces` Development LocallyThe problem with front end development in the cloud is that it is painfully slow! Unfortunately this is the reality of the cloud nature of SF and it will remain so - at least until there will be ability to spin up local SF development servers. It takes about 30 seconds or more to save on a busy org. That is mainly because of the typical save cycle, 'change', 'zip', 'save to server', and then 'refresh in browser':doing this many times a day adds up to a substantial time lostloss of focus/concentration - while you wait‘clobbering of static resources’ when working in a teampure maddening in tight timelines

Fix for 'unknown ACL condition/modifier in "spam = debian-spamd:true"'

Exim configuration error in line 438 of /var/lib/exim4/config.autogenerated.tmp: error in ACL: unknown ACL condition/modifier in "spam = debian-spamd:true" root@sh1:/etc/exim4# dpkg-reconfigure exim4-config 2015-10-25 14:09:40 Exim configuration error in line 438 of /var/lib/exim4/config.autogenerated.tmp: error in ACL: unknown ACL condition/modifier in "spam = debian-spamd:true" Invalid new configfile /var/lib/exim4/config.autogenerated.tmp, not installing /var/lib/exim4/config.autogenerated.tmp to /var/lib/exim4/config.autogenerated The one stumped be for a bit but the solution - at least on a Debian based system - is to ensure you have installed 'exim4-daemon-heavy` instead of the light packages, aptitude install exim4-daemon-heavy.If this has helped comment of follow me .

Linux Benchmarking

Simple Linux Performance ScriptWhen deploying new virtual machines with different provides I like to do basic performance tests using built in utilities like `dd` and `bc`. I had a little script linux-benchmark.sh which I have now cleaned up and making it public. When run it will do basic test for HD, Internet and CPU and save it as a timestamped text file.Sample output: root@sh1:~# ./linux-benchmark.sh Please be patient, this might take a minute or so.

Linphone keys (DTMF) not working with Freeswitch VOIP Server

Work around to key tones not working in Linphone when connected through FreeswtichIf you find that after dialing into any IVR your key presses are not registering, and you are connecting to a Freeswitch voip gateway it is likely due to this Bug: Telephone-event codec clock-rate mismatch (leads to DTMF issue); go 'Options > Settings > Codec' and move the 8000Hz codes up.A temporary work around is to change your codec priorities in Linphone to use one of the lower quality 8000Hz ones first.

dnsmasq as an external DNS server

Creating a 'NS' record It's NOT possible - try setting u BIND instead or contacting the author to add support for it; I am creating this entry so that it would save hours of searching for others.
The basic setup that should work is to point your domain dns servers to to 'ns1.yourdomain.com` where ns1 resolves to your servers IP, however because dnsmasq can not answer with a NS record and the process fails - that is my understanding based on my readings

Windows Insider stuck at build 10162

Windows Insider won't updatedSo my 10162 insider windows edition is now expired, keeps restarting, telling me it will stop working and yet Windows Update says there is no updates.

Salesforce Sortable Changeset Dependency List

Sorting the results of 'View/Add Dependencies' When you have to shift through over 100+ entries it would help if SF's interface allowed for sorting. The missing functionality can be achieved by running the below JS, which can be invoked using a handy bookmarklet. Create one as follows:
In your browser add a new bookmarkName it `SF Make `<table class='list' ...>` Sortable`In the url paste the blelow JS snippetjavascript:/* `sortTable` from https://gist.github.com/danielsokolowski/994d47baa95ef81fd8fc */ function TableSort(a){this.tbl=a;this.lastSortedTh=null;if(this.tbl&&"TABLE"==this.tbl.nodeName){a=this.tbl.tHead.rows[0].cells;for(var b=0;a[b];b++)a[b].className.match(/asc|dsc/)&&(this.lastSortedTh=a[b]);this.makeSortable()}}TableSort.prototype.makeSortable=function(){for(var a=this.tbl.tHead.rows[0].cells,b=0;a[b];b++){a[b].cIdx=b;var c=document.createElement("a");c.href="#";c.innerHTML=a[b].innerHTML;c.onclick=…

Compass can't find any Sass files to compile.

Is your compass configuration correct?.Unbelievable, compass chokes on directories with spaces (I think, and at least on a Windows machine).I have resolved it by creating a junction from the repository into a folder without spaces - see this awesome utility: http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.htmlAnd food for thought: consider if SASS is needed, do you want to debug your SASS or CSS? If this post has saved you hair pulling post a comment and a follow is always appricited.

Freeswitch 1.4 'mod_shout' compiling fails on Debian 8.0

Error: inlining failed in call to always_inline '_mm_loadu_ps'The error happens when trying to compile the 'lame' needed by the 'mod_shout' module. From Google it appears to only happen on 32bit architecture. The solution is to search for `xmmintrin.h` and remove the line from file `./lib/lame-3.98.4/configure`. The final code block should look as follows: ... for ac_header in \ errno.h \ fcntl.h \ sys/soundcard.h \ sys/time.h \ unistd.h \ linux/soundcard.h do : ...

Google Hangouts Crashes Chrome

Latest stable Google Chrome crashes when starting Google HangoutsThis is on Windows 10 Preview, updated drivers, updated flash, clean Chrome install, re-installed Chrome, deleted user profile - all of these failed to resolve the crash when trying to start a Google Hangouts. Solution is to un-install Google Stable and install Google Canary. Feel free to comment or follow me on twitter @danielsokolows if this post has helped you.

Salesforce "Save error: An unexpected error occurred."

Description Path Location Type Resource Save error: An unexpected error occurred. Please include this ErrorId if you contact support: 693681547-51638 (-1906541512) ... line 0 Force.com save problem ... The blackbox that SF is does not lend it self to debugging so this one took me a while to track so if this post has helped you do comment or follow me on twitter :). The cause was using `this` keyword in my bind SOQL variables and removing it fixed the problem.Looks like a bug if you ask me to me. If you find others send them to me or comment and I will update the post. oOrderedContentIds = [SELECT Id FROM cms__Content__c WHERE Id in :oPrunedContentRenderingsMap.keySet() ORDER BY cms__Original_Published_Start_Date__c DESC LIMIT :iQueryLimit // *NOTE:* using `this.` keyword will crap out with unexpected error when saving OFFSET :iQueryOffset]; Be great

VirtualBox vs. VMware - choose neither and use Hyper-V instead

Free built in Hyper-V in Windows is a fantastic free productIn an effort to self host my Linode server my research has led me to decided to Virtual Machine to run a Debian distribution. Those interested might want to know that I have fully explored other options mainly OpenWRT or running Debian on a beefy MIPS processor; former failed due to lack of proper packages, latter failed due to the difficultly hacking Debian onto MIPS and the lack of tailored router interface.The two main products a quick Google search returns are VirtualBox and VMWare Player, both are free but I was leaning towards VMWare because - it is my understanding - it's native format can be uploaded to an online host as is. However to my big surprise Microsoft provides it's own Virtualization software built into Windows 8.1. It's fantastic to use, full of professional features such as VM auto start for and seems to have better virtualisation as I was able to adjust the console's frame buffer resolution…
