So, this afternoon, I picked up the Samsung Dex Pad. Some of you will recall my earlier blog post bemoaning whether or not I can survive on just a tablet, and whilst I actually have a Citrix M1 Mouse for the iPad on its way, I also decided to pick up the Dex Pad, as a potential thin client replacement for my bedroom.

This little doohickey is the next revision of the Dex Station which was released with the Samsung Galaxy/Note 8 series. This version, released with the Galaxy 9 series – requires any 8 series devices to have Android Oreo as a base release for the OS for backwards compatibility.

It supports up to 2K resolution, has a built in cooling fan, and uses a platform based docking form factor, instead of a puck-shaped vertical factor. It makes a lot of sense actually, as it lets the phone be used as a trackpad or keyboard as required, should no extra input devices be available. It’s a very clever idea, one that I’m sure would be welcome to a lot of semi-mobile workstation users.

I’m actually writing this post at around about midnight, and it’s quite late, having just received the device to take a look at, the initial overall impression of the device, having spent about 10 minutes with it.

First off, this is what the browser looks like, running on a 1080p screen:

It’s perfectly usable, and I have no issues writing posts (in fact, this very post is being written via the Dex) for my blog, or doing basically productivity work. Where the big test comes in, will be on remote streaming for desktop, and gaming.

Dex MAX – an invaluable tool

So, to my horror, a lot of the apps on Dex don’t support full screen resolution – including Microsoft RDP. To fix this, I actually had to download this 3rd party companion application, Dex MAX – it’s a life saver. I probably would have returned the Dex Pad if this app did not exist.

It tries to force the apps to run full screen, and if it doesn’t work – you can enter expert mode and modify the manifests in the APKs to force a full screen mode! If that doesn’t work, then the devs will need to add native full screen support in a new version of the app.

Remote Desktop (Microsoft RDP Client)

As one of the primary reasons for an enterprise environment etc, I know a lot of organisations out there use Citrix, VMWare, etc. but you’d think that getting basic Dex support with Microsoft would be a key step. Especially considering how prolific the operating system is…

However, no, it doesn’t work without being modded by Dex MAX. Here’s a screenshot of it working in Dex MAX:

Now, it works perfectly fine as an RDP client, meaning about 90% of what I do is sorted. Productivity wise, I can scrape by as well as needed!

So all in all, it’s a pretty stable experience. It’s not the ultimate replacement, but for everything non-entertainment wise or just general browsing, it’s fine. It’s usable, and I probably will use it.

In part 2 – I’ll update my findings on gaming, which works (with many many caveats).

This is mostly a personal note on how to setup a workflow with my Web Development (PHP/MySQL & Docker based) projects. Usually, with pretty much any project, the workflow goes as follows:

Figure: My workflow prior to this article

To host my own repositories of codes per project, I actually use GOGS which is short for Go Git Service – it’s written of course, in google Go, and is essentially a self-hosted Github clone. It’s by one of the devs from the Gitlab team, and it’s far more lightweight and easier to use in a personal scope, than Gitlab (Gitlab is still wonderful, but I think it’s better suited to teams of 2 or more people).

Git hooks are amazing!

The above workflow diagram though, is missing one really critical stage – getting the code to production – a.k.a. deployment. Typically on any deployment, after the above workflow, I’d either remote in, or set up a cron job to pull from master. There’s some problems with this method of doing things:

1. I’m doing a git pull which is based on merges, and can really cause some shit if there’s a conflict (there shouldn’t be, but just in case)
2. I’m remoting into the server each time I have to pull for some commits, this takes up time. I’m a serial commit/push-as-save person
3. It’s completely against the ethos of a developer. If I’m doing something repeatedly, I should find a way to automate it!

So, enter stage – Git hooks. Git hooks are amazing! They’re actually natively supported by Git (powered by Git) and I only really just started learning about using them. I vaguely recall encountering them earlier in my growth as a dev, but I must’ve shelved it at some point and given up trying to learn hooks (probably around the same time I cracked it at Drone CI, and Jenkins CI/CD).

Anyway, the overall concept of using a Git Hook is that I reach the final stage of the workflow I drew at the start of this article Git push to remote repository – the idea is that the Git repo then registers this push in something called a post-receive hook. It then performs some functions and essentialy plonks a pull of the latest code of my repo, into the production environment.

At first, I started off with something super simple, from my jtiong.com (this website!) repository as an example:

#!/bin/sh
ssh [email protected] 'cd /var/www/jtiong.com && git fetch && git reset --hard origin/master'

Unfortunately, this didn’t seem to work. I kept getting remote: Gogs internal error messages, and figured out it was something to do with my SSH keys not working in the authorized_keys and known_hosts files of the docker container to server shell and vice versa. After a lot of Google-fu and tinkering around, I eventually came up with the following which worked (note, it’s been edited to be a generic solution).

#!/bin/bash
ssh -o StrictHostKeyChecking=no [email protected] -p 22 -i /home/git/.ssh/id_rsa 'cd /project/folder/path && git fetch && git reset --hard origin/master'

It’s not entirely necessary, but I used the -p and -i options to specify both the SSH port and identity file used with the SSH connection (just for greater control, you should be able to remove them, your results may vary). The key section of the above command that I want to highlight is the -o StrictHostKeyChecking=no option that I’ve set. This got rid of any Host Key issues between the docker container and the host server for me. So if you’re encountering issues with your Host Key Verification or similar, this might fix your problems!

With the git command now, I used git fetch && git reset --hard origin/master instead of just doing a git pull. Why? Because git pull uses merge methods and can result in some conflicts with code, and issues that are just messy and a bad experience to untangle. Using git reset, moves the code’s pointer to a different commit without merging anything. It just overwrites it, making it slightly safer for deployment!

But of course… Why do things in just a simple way? This particular hook configuration is great for something like my personal site where I don’t mind if I’m pushing breaking bugs to production (within reason). However, when I’m doing work for clients, I need to be a little bit more careful – and I use a more typical production, staging, development branching method with my Gitflow.

Here’s what I use now:

And wonderfully – this lets me have separate branches, as required and updates the appropriate (sub)domain as needed! The wonder of Git Hooks has now streamlined how I develop projects, and deploy them in a much more pain-free manner! And so I dramatically take another step in my journey and growth as a developer haha 😛

So, I’ve started dabbling in games development with a few game ideas I’ve got bouncing around in my head. And whilst I wanted to make wonderful, amazing, visual feasts of games – I also wanted to start a bit slower and ease myself into what is essentially the most difficult discipline of software engineering around.

Cue, LÖVE – an engine dedicated to 2D games (there are 3D libraries available for it). It uses LUA, and pretty much encourages diving straight into the code and learning how to make a game, as opposed to learning the tools and figuring out how to use a suite of (albeit amazingly powerful) tools.

I worked on some basic tutorials last night, and I’m enjoying learning both LUA and the engine right away. It’s quite logical from what I can tell so far and I found a few tutorials especially helpful in understanding what’s going on:

• this tutorial about Tilemaps by Kikito helped me understand how to use spritesheets, and make use of them effectively
• your first game in 200 lines by OSMStudios showed really, how quickly games could be thrown together (perhaps good for future GameJam participation?)
• basic platformer tutorial from OSMStudios also shows different kinds of movement and techniques

I’ll probably start blogging a little bit about my upcoming game idea and my adventures in tinkering around with the LOVE 2D engine. So stay tuned!

Remote Desktop more than covers my use of productivity on JT-NXS, my laptop system that’s based at the office. So far, I’ve been fortunate in the last 10 days or so since moving towards ‘Cloud Citizen’ status, that I’ve been at my desktop, JT-DXS and not needed to use JT-NXS as much for productivity.

The experiment so far has been a wonderful success, especially when it comes to Media Consumption – it’s been awesome being able to access a personal collection of media that some close friends and family are also able to access.

Gaming has been great, for anything that’s not on a pressured level (ie. competitive play like Overwatch, or CS:GO – even then, they’re fine, but I just feel more comfortable not leaning on the internet connection so much to remain competitive with other human players). Co-op games are a revelation with it, Parsec.tv have really outdone themselves in their compression algorithms and gaming performance over the net.

I think, if when I pass probation at my workplace, I’ll commit to buying a mini-ITX system to accommodate a spare GTX 1070 graphics card I have, and allow for a bit more storage space too (dual 4TB drives + 3TB existing storage)

I’ve got plans at least, to rearrange my equipment at home; to minimise waste, and reduce the soaring temperatures in my bedroom, too. Even in the dead of winter it’s still a warm toasty room that can get quite uncomfortably stuffy as well.

Anyway, 10 days in and I’ve started rolling out some productivity tools onto JT-NXS in anticipation of using the system for more work-related and project-related situations.

I’ve got:

• Git, with Git Bash as my terminal
• Adobe Creative Cloud
• Visual Studio Code
• Office365

For the most part, I actually already use Google Docs/Spreadsheets almost obsessively to manage my documentation, and I’ve got my own personal BookStack that I use as a personal Wiki and Knowledge Repository.

All in all, I’m slowly training myself to wean off my attachment to my desktop, and to be able to start working from anywhere on a laptop (an old Microsoft Surface Pro 1 – although I plan to use JT-NXS in 3 months time) or tablet (iPad Pro).

So, primarily to get away from my desktop (see my previous post below) – the solution appears to be resorting to Cloud computing in some shape or form.

Gaming Entertainment

The biggest issue currently, that will dissuade me the most from becoming a citizen of the cloud is that I won’t be able to play games with my low-spec terminal (in this case, in my room, it’ll be a 2012 Mac Mini).

Luckily for me; I actually stumbled across a wonderful solution! Parsec.tv – an amazing, free, 1080p 60fps cloud gaming application. Steam In-Home Streaming has never worked well for me, but this evening I gave it a go with a brand new release Sea of Thieves!

The experiment worked spectacularly – the quality of the game is more than adequate. My Laptop (off-site) reached on average about 40fps; and the input lag was more than acceptable for adventuring, fighting the undead and firing cannons to deal with opposing pirate crews.

The image quality was great – it was slightly higher than an average 60fps 1080p Twitch stream. Here’s a couple of example screenshots:

The strange blue ‘honeycomb’ icon in the top-left, is Parsec’s hot-spot; you can click that to disconnect/connect with the host machine; or you can recalibrate your gamepad controller – which gets input into the host machine as an XBOX Controller.

There was only one real concern – my laptop reaching 95 degrees in CPU temperature (Speedfan told me it was 88 degrees, but NZXT Cam monitoring told me it was 95). It looks like I’ll need a laptop cooling pad 🙁

Movies & Media Entertainment

The other thing I’d like to do, is somehow migrate my personal media collection, into the cloud. Something that’ll let me stream no matter where I am, should I be on holidays, or working.

Cue, Plex Media Server – a system so consistently awesome in delivering movies and shows across both a network and the internet, with built in media conversion and on-the-fly media management, I can’t really see myself needing any other system to deliver access to my collection of media to friends and family.

Whilst the quality isn’t terribly awesome (it’s slightly worse than Netflix is), it delivers a more than watchable result provided the source files themselves are of a high quality.

Here’s an example of one of my favourites, Kingsman: The Secret Service:

As you can see, it’s a little murky, but still delivers on the visuals enough. The source file isn’t in a 1080p resolution, but it is still clear enough to watch!

So, all in all – we got through all the fun stuff; being a netizen of the Cloud is a doable thing in Australia – provided you have a 1Gbit internet connection, I suppose.

I’m aware that I’m in an extremely fortunate position to be able to do this; and will continue my experiments and foray into being more integrated into The Cloud™ in time for when the NBN reaches (if ever) my residence.

I’m going to be updating this blog again shortly with some thoughts about being both a “Cloudygamer” and a “Low Spec Gamer” to better handle and optimise my graphical usage; so please stay tuned!

Since the start of the year, I’ve been working towards making the technology and capabilities of the tech I use in my every day life, a whole lot more comfortable and less cluttered.

I’ve been looking into a minimalist lifestyle after realizing whilst trying to plan on moving out – that I have way too much crap in my life to accommodate such a move.

There’s a pretty simple rule/goal I keep in mind now with each of the gadgets, tech or ideas I have:

It should, as seamlessly as possible, integrate into my everyday life and tasks. I shouldn’t have to worry about how I’m doing something, or if I can do something.

And the best way I can think of that, is to no longer be tied to a desk in order to do all the programming, design, development, gaming and media consumption.

It would enable me to have a much more enriched quality of life, being able to go out, and adventure around, and when it all gets a bit much, I can just reach through the internet and hug the comfort of my favourite IDE, or enjoy something from my personal, (and carefully) curated media collection.

I’m going to need to join The Cloud™. I’ll be calling this experiment, “Project Cloud Citizen“!

Sounds alright – and I think, very doable if you were based in North America, Western Europe, Korea, Japan, Singapore or Scandinavia. Coincidentally, friends in all those regions are the ones who talked to me about this.

It’s a way more difficult thing to achieve in Australia, where traditionally, the concept of a decent upload speed for data sharing and enrichment, hasn’t existed until the arrival of Netflix, and even then, leaders of society in Australia still think it’s just next-gen TV.

Getting away from the office desk at home

As it currently stands, I’m fortunate enough to work at an office that allows me to keep a laptop present in the office, that in theory, is connected at all times.

This laptop isn’t a snooze in terms of specs:

• Gigabyte Aero 14
• Intel i7-7700HQ
• NVIDIA GeForce GTX 1060
• Kingston 16GB (1 x 16GB)
• Gigabyte P64v7 Motherboard
• 500GB SSD (TS512GMTS800)
• Windows 10 Home

Why do this?

Reason #1

I want to be untethered from the restrictions of only being able to show friends & family games, or media that would be accessible within my home office.

I’d like to be able to develop code and access a remote system that is my own without having to carry around or go through an elaborate setup process.

Nowadays, more than ever, a combination of my iPad Pro and Samsung Note 8 cover all my usage that isn’t coding, or gaming. And even then, they begin to encroach on coding, and sometimes gaming!

Reason #2

Where I use my PC at home is an oven with my current PC setup; no joke, I run an incredibly complicated setup that I think is overkill for pretty much everybody except the most hardcore of PC gamers.

It’s messy, it’s finicky, it’s expensive as all heck and it provides the best damn gaming experience I’ve had the pleasure of using.

But in the sweltering Australian summer, it’s untenable with my neighbour’s air conditioning exhaust being about a metre away from my window, and the combined heat of my PC + 3 monitors, and consoles + TV, it becomes somewhat unhealthy, if not overly sweaty.

This is cheaper than buying air-conditioning myself

Reason #3

On a personal level, I feel like the majority of the time that I don’t want to go somewhere or spend time elsewhere outside of the haven I’ve built at home, is because I feel like I don’t have the access to my files and work to tinker with as I go along.

Coding and tinkering with various web projects has become an almost safety blanket to what I do.

The first test

Over the course of a weekend, I went ahead and did some very rudimentary testing of some functions I’d be performing.

Of course; a speed test is in order:

I’m pretty content with the speeds! My main concern was the upload speed of my laptop; which as you can see, can more than handle the 1080p streaming I was intending to do with it.

I’m surprised the USB 3.0 to Ethernet dongle I was using didn’t crap out! (cheers to my mate: Matt for providing the adapter)

Note to self though, in the future I’ll need to take photos or screenshots of my screen streaming for image quality comparisons (I know streaming will always be worse in terms of visual acuity, but by how much is worth quantifying)

Gaming

Over the weekend, I used a combination of TeamViewer, Hamachi and Steam In-Home Streaming to get a few games going. The image quality felt something akin to watching a twitch stream; there was occasional ribboning of colours in fast-moving games, but aside from that, it worked flawlessly. The almost low-spec restrictions of the laptop forced me to consider playing some of the more indie games in my backlog too.

Rocket League, Hammerwatch, Torchlight all got a go – and I have to say, the only times the frames or input stuttered were more the lack of power behind the laptop and its unoptimised configurations (they were all set to high settings etc.).

Media

Plex had a couple of movies I played to both a friend and myself (Kingsman is a great movie!) simultaneously.

The quality was superb, and stress on the laptop was more than manageable!

Productivity

Admittedly, I did this through TeamViewer, which is rubbish for such situations anyway. However, it was acceptable! There was some input lag, but that’s more TeamViewer’s crappiness as opposed to any other laptop issues. This I expect, should be resolved with proper Remote Desktop access (I’ll need to change to Windows 10 Pro).

Overall, I think the first test was a success, and it’s time to start planning a serious configuration for this application!

I’ll try to keep it well documented 😛
