Since I posted this post (Transitioning to AWS), I completed the Udemy course, did plenty of hands on and proof of concepts to enable me to learn, I soon after discovered Azure. This was totally by chance – I went to a Cloud Meetup group in London where both AWS & Azure solutions were discussed, and curiosity got the better of me. I started by using the free credits by Microsoft on the trial account (which are only valid for 1 month), but immediately I was hooked. I was creating Virtual Networks, Network Security Groups, VMs, Load Balancers, reading how to create hybrid clouds, how to migrate from on premise servers to Azure using Azure Site Recovery, and how to automate deployment with ARM templates. Instantly this felt much more mature and a better rounded solution than AWS. Microsoft really has come a long way since Azure was first launched.

So this lead me to investigate the certification route, and I have decided to take the following exams:

70-533 – Implementing Microsoft Azure Infrastructure Solutions – Exam LinkBook (Released Feb 2018)

70-534 – Architecting Microsoft Azure Solutions – Exam LinkBook (Released April 2018)

So with new books not due to be released for a few months, we can only assume the exams will be going through a refresh – I will guess by removing or reducing the amount on the Classic Portal and focusing on the new Azure Portal.

 

So what am I currently doing with Azure other than labbing? Well I’ve moved my production servers to it already, I am working with a local charity to move some ageing Windows and Linux servers hosted in their office and in a DC to design a solution and migrate to Azure, and I am working with a small MSP to help them satisfy an Azure migration requirement/opportunity with a customer, and enjoying it.

I’m quite liking my Huawei Honor 9, and even EMUI 5.1 (see review here), but one thing I am really missing from my Oneplus One is the double tap to wake. That was such an awesome feature which soon became prevalent on many other handsets, so imagine my dismay, shock and horror when I couldn’t find the option on the Honor 9 / EMUI 5.1. Seeing as I was routed I quickly tried the steps detailed here (adding a line to build.prop and changing a line in /system/emui/base/hw_easywakeupmotion_config.xml files), but no joy yet  – it seems that the option isn’t exposed through the GUI unfortunately :/

I’m quite new to cryptocurrencies, but understand the high level theory, and have never had any need to buy any of the now famous Bitcoins for any reason, however recently I have tried to purchase some Monero (XMR) but wanted to pay in GBP. This has proved more challenging than I first thought it would be! Quite a few exchanges will convert Bitcoin to to XMR, but I couldn’t really find any that would take a direct payment in GBP and convert to XMR, especially at a reasonable rate. So I had to buy Bitcoin in GBP, then convert to XMR. Here is the route I took: More »

After my last Erisin ES9746A Android head unit died whilst performing a hardware mod to improve the rather poor sound quality I hung on and waited for one of the new Intel Sofia 4 core based units – the first to release with an OEM E46 look was Joying, with their JY-BL12N2 model.

I have collected some useful links for this and other Intel based units below, mostly from XDA.  Note these are not MTCB/MTCD units, despite the threads residing under thoes sections!

 

E46 JY-BL121N2 General Queries – also includes info on the reverse / gearbox switch

Large general thread on Intel units – New Joying Android 5.1.1 2GB Units available very soon !

Steering wheel key customization – V3 (NO KILL) – stop processes killing on hibernate and key reassigning

General Roll Up / tips and tricks thread

Joying Feb 22nd 2017 Update – info on the latest update

 

Overall I am happy with this unit – it is lightening fast compared to my old dual core MTCB, the screen is much higher resolution and importantly the on board DSP is way better than the previous MTCB!  I have rooted, installed Viper4Android to tweak the sound further, and plan to add a reverse cam and DAB USB receiver next.

I was trying to use a website in Chrome which used WebGL through an RDP session to a Virtual Server 2016 (VMware) but was hitting an error about WebGL disabled.

There are various posts on the Google product forums but I couldn’t find the definitive fix there, although they pointed me in the right direction, in Chrome:

chrome://settings

  • Make sure use Hardware Acceleration is enabled

chrome://flags

  • Override software rendering list Mac, Windows, Linux, Chrome OS, Android
    Overrides the built-in software rendering list and enables GPU-acceleration on unsupported system configurations.  – set to ENABLED
  • Accelerated 2D canvas Mac, Windows, Linux, Chrome OS, Android
    Enables the use of the GPU to perform 2d canvas rendering instead of using software rendering.  – set to ENABLED
  • WebGL Draft Extensions Mac, Windows, Linux, Chrome OS, Android
    Enabling this option allows web applications to access the WebGL Extensions that are still in draft status.
  • WebGL Draft Extensions Mac, Windows, Linux, Chrome OS, Android
    Enabling this option allows web applications to access the WebGL Extensions that are still in draft status.  – set to ENABLED (if required)
  • WebGL 2.0 Mac, Windows, Linux, Chrome OS, Android
    Allow web applications to access WebGL 2.0.  – set to ENABLED

Restart Chrome and…bingo – it seems nobody enabled the top option, to override the GPU blacklist

I now feel like “cloud” (/i.e. somebody else’s computer/infrastructure) has matured considerably with many companies making the transition to move core infrastructure to a cloud based operational model, particularly if the main product of the company is a web application which would previously have been hosted on traditional infrastructure.

This traditional infrastructure (usually some from of virtualisation (VMware for me), storage and networking) has been my bread and butter core skillset for many years. I have translated many business requirements into technical requirements, and then installed and configured them. Its what I know best and have served me well for many years, but particularly in the last 12 months there is a very clear decline in demand, and a very sharp rise in revenue spend with cloud based technologies.

Obviously not all infrastructure will fit into the cloud as it stands now, and maybe some never will, but there is a clear pattern here which cannot be ignored, and as ever in IT it is important to keep up with trends.

So now I am open to the cloud adoption it will become easier and more efficient to begin learning. So, where to start and why? I chose to master the AWS offerings – not all of them, I don’t think anyone has done that, but at least the core offerings – compute, storage, networking, automation.

Why AWS? The are the clear market leaders and have held this position for many years and although Microsoft is the nearest contender with Google trailing, they are a long way behind. Sure they may start to eat into AWS market share in a few years, but I don’t think they will make a serious dent. Now the model is well proven, it is time to start learning!

So where to start?

I have decided to take the exam AWS Certified Solutions Architect – Associate which gives a good overview of the core service offerings and how they interoperate with each other, as well as benefitting from obtaining an industry certification.

For study aid I am watching the well recommended video by A Cloud Guru which is ideal for beginners to AWS right from the start and of course lots of hands on in the form of AWS labs.

I needed to use iLO to remotely administer an HP DL360 G5, but the combination of modern Java and Windows 10 equaled no joy. A quick update from the top of my head:

  • Update iLO to 2.25 via SSH (my browser(s) wouldnt upload the entire file.  Instructions here, download iLO2 2.25 here.  Be patient, this takes ~10 minutes
  • Set Java security.  Add site to exception site list under Security tab (I added the URLs in the format https://x.x.x.x/*, https://x.x.x.x:443/*)
  • Under Advanced tab of Java disable “Use TLS 1.2” and “Use TLS 1.1”
  • Under Advanced tab Check TLS Certificate Revocation Checks – Do not check (unsure if needed)
  • Use Internet Explorer (IE 11 in Windows 10 worked)
  • Login to iLO, Remote Console tab, Remote Console (Access the system KVM from a Java applet)
  • The first time the pop up loads it errors with unable to load class something something something.  Close this window
  • Back in the main iLO window click back to System Status tab, then back to Remote Console tab and try again – Bingo!

It has been possible to use Vodafone wireleless on the London underground for some time and according to Vodafone’s info page your phone should connect automatically.  Mine didn’t and neither do many peoples on Vodafone’s support forum.

I hadn’t had the need to use WiFi on the underground as I only traveled very sporadically for work into London, but now I’m doing it daily I thought it would be useful. Well it would have been had it just connected automatically – it didn’t.  Vodafone’s suggestion for if it doesn’t automatically connect is to use the “Virgin Media” WiFi, which although it works it takes you to a captive portal page and requires you to sign in with your Vodafone user name and password.  That’s a bit rubbish as when passing on the tube you ate only stationary for about 20 seconds.

I recently had a to take my MCSE renewal exam (70-980) and thought I’d give the Pearson Vue online proctored exam version a try rather than driving an hour each way to my nearest choice of low rate testing centres (think cheap nasty low cost slow white box computers, sometimes cramped cubicles, parking issues, date/time availability issues – yes I’ve had bad experiences of all of the above!). As an IT consultant time is nearly always in short supply and very limited testing centres offer testing on a Saturday. My reasons were numerous for trying the online delivery of the test:

  • Can book on the day for a start time up to 9PM
  • No travel time and cost
  • Luxury of taking it in my home study, set to a comfortable temperature and no other disruptions
  • Decent powered desktop computer
