Doom tweak and articles

As I am quite keen on the Doom2016 multiplayer the tweak that has worked well for me on moue smoothing, removing the startup videos, and start in multiplayer mode. Open your steam library / second click on DOOM / properties / general tab / set launch options / set as "+com_gameMode 2+com_skipIntroVideo 1+set m_smooth 0+com_skipKeyPressOnLoadScreens 1" without the quotation marks. Strange that it contains spaces but is functional.

Developers can have a life outside of coding, which is good to know.

IEEE article about the use of body cameras, some of it makes sense the part around speed cameras I am not convinced as the last article I read about them was that a number of UK stats did not include regression to the mean regarding the frequency of accidents post camera installation.

Vector is a synonym for a one dimension array in programming.

For Java bits and pieces, packaging up apps with jar can be a pain I do find the class path a bit hard to get my head around, 7zip is handy for opening jar files. And after all of that and feeling crazy, line break is the delimiter for commands in the manifest so I was typing Main-class: aPackage.Main where I needed
Main-class: aPackage.Main new line!

Doom makes my graphics card hot

The temps are a little high at the moment, back of the card running at 60c, which seems a little hot. With the case closed nothing seems happy. Thinking of moving the graphics card down a couple of slots as between the card and the CPU is the m.2 drive.

shows back of gfx card close to system memory and cpu cooler, and secreted under that is an m.2 hdd




Note: there is space between the cooler and memory just a limited amount. 


Getting there with the Java OCA mocks, knocked out 79%, pass rate is 65. Getting that booked soon.

Actually liking the book think like a programmer by Sprual, he does have a youtube series which has extra content, very handy as I thought I was alone in finding it hard just to break problems down which requires practice.

Another guy I found this week, funfunfunction youtube channel, easy to follow for breaking down complex issues, he seems to mostly do java script and easy to follow.

Getting linux working is harder than it looks

It is harder than it looks, my idea would be to have a persistent install on USB stick which then some bios boot order fiddling, plug in stick boot Linux or no stick boot windows.

What I wish I knew then, Ubuntu can actually have its boot loader on the motherboard because of how UEFI works which is all new to me, I hope I have that right. So I thought I had broken my windows install for a while as no OS found. It is in the bios to change between the different types. After all of that secure boot needs to be turned off. 

Solution which worked best for me has been hyper V, selecting a gen 2 machine having added a graphics card and networking makes it much more useful. The networking takes a bit of fiddling as it has to be set to use a switch with external access, assuming network access is required.

Ubuntu after all of this was giving me a hard time lots of scrolling error messages, SUSE worked just as is, it only complains about the pci not having any configurable space.

I am quite happy playing with the terminal, handy tip which would have been useful to me years ago, when video files used to be shared in multiple parts you can join them together with the cat command unlike my erm friend who would play each file in turn.
