Nowadays, it is quite difficult to imagine any application that would not use the database whether it is a server, personal computer or mobile device. Database usage is widespread - from simple games to serious business applications of international corporations. They all process, read and write a specific set of data. Each system supports different database models and structures. These models determine how the created DBMS will operate with data. There are quite a few database models that provide ways to structure data and now we would like to represent the most popular solutions of this industry in comparison with an immutable and replicable Credits Database based on Key=Value (NoSQL) principles.

MongoDB
MongoDB is an open source database management system (DBMS) that uses a document-oriented database model which supports various forms of data. It is one of numerous nonrelational database technologies which arose in the mid-2000s under the NoSQL banner for the use in big data applications and other processing jobs involving data that doesn't fit well in a rigid relational model. Instead of using tables and rows as in relational databases, the MongoDB architecture is made up of collections and documents.

MySQL
MySQL is an Oracle-backed open source relational database management system (RDBMS) based on Structured Query Language (SQL). MySQL runs on virtually all platforms, including Linux, UNIX and Windows. Although it can be used in a wide range of applications, MySQL is most often associated with web applications and online publishing.

Oracle DB
Oracle database (Oracle DB) is a relational database management system (RDBMS) from the Oracle Corporation.The system is built around a relational database framework in which data objects may be directly accessed by users (or an application front end) through structured query language (SQL). Oracle is a fully scalable relational database architecture and is often used by global enterprises, which manage and process data across wide and local area networks. The Oracle database has its own network component to allow communications across networks.

Credits Blockchain DataBase (DBMS)
Credits Blockchain database system is a data storage system based on the blockchain technology (data is packed into blocks and all blocks are interconnected, which generates a chain of blocks) This technology allows for immutability and high reliability of data. The toolkit allows you to create the desired data format that will be stored in the database easily and quickly. The storage is highly optimized, which makes it possible to reach high read / record speeds. The support of native data compression is built-in to the storage, which helps to achieve the reduction of the necessary storage resources (LZ4 algorithm). The storage is an array with data represented in the form of Key, Value. That allows you to achieve high speed of read / write / search of the necessary data by key.

Primary database model

MongoDB
Mongo DB is a document-oriented database system, characterized by their schema-free organization of data.That means:
  • Records do not need to have a uniform structure, i.e. different records may have different columns.
  • The types of the values of individual columns can be different for each record.
  • Columns can have more than one value (arrays).
  • Records can have a nested structure.
MySQL, Oracle DB
MySQL, Oracle use relational database management system (RDBMS) model thats supports the relational (=table-oriented) data model. The scheme of a table (=relation schema) is defined by the table name and a fixed number of attributes with fixed data types. A record (=entity) corresponds to a row in the table and consists of the values of each attribute. A relation thus consists of a set of uniform records.
The table schemas are generated by normalization in the process of data modeling.
Certain basic operations are defined on the relations:
  • Classical set operations (union, intersection and difference)
  • Selection (selection of a subset of records according to certain filter criteria for the attribute values)
  • Projection (selecting a subset of attributes / columns of the table)
  • Join: special conjunction of multiple tables as a combination of the Cartesian product with selection and projection.
Credits Blockchain DataBase (DBMS)
The Credits Blockchain DataBase model is very simple. It is a structured data with a pronounced structure of key and data (the key can be a composite or perform some characterizing function, the result of which is a unique representation of the data set in the Value field). The system has no SQL language, which affects the need to use third-party search and data retrieval techniques. The database is a NoSQL solution, which allows to abandon the relational interactions between the stored data and achieve the speed comparable with the speed of work with the file system.

Supported programming languages

Mongo DB
Actionscript, C, C#, C++, Clojure, ColdFusion, D,Dart, Delphi, Erlang, Go, Groovy, Haskell, Java, JavaScript, Lisp, Lua, MatLab, Perl, PHP, PowerShell.
MySQL

Credits Blockchain DataBase (DBMS)
The system supports С / С ++ and similar languages at the native level. SDK is used to work with all languages is developed for the needs of the DBMS. This allows to achieve unification and standardization of interaction with the database and simplified integration with any other system.

Partitioning methods

Database technologies use different methods for data storage.
Mongo DB
Mongo DB implements sharding with best practices baked in. Sharding is a method for distributing data across multiple machines. MongoDB uses sharding to support deployments with very large data sets and high throughput operations.
Database systems with large data sets or high throughput applications can challenge the capacity of a single server. For example, high query rates can exhaust the CPU capacity of the server. Working set sizes larger than the system’s RAM stress the I/O capacity of disk drives.
MySQL
MySQL automatically partitions tables across nodes on the base of MySQL Cluster, which is a synchronous mostly memory-only key-value store that allows a shared-nothing architecture for MySQL (providing a backend to the NDB Engine). It provides automatic sharding, enabling databases to scale horizontally on low cost, commodity hardware to serve read and write-intensive workloads, accessed both from SQL and directly via NoSQL APIs.
Oracle DB
Oracle Partitioning method allows tables and indexes to be partitioned into smaller, more manageable units, providing database administrators with the ability to pursue a "divide and conquer" approach to data management. With partitioning, maintenance operations can be focused on particular portions of tables.
Credits Blockchain DataBase (DBMS)
Data is stored in an associative array according to the Key-Value principle. The value contains the complete data set, with the length and the type of stored information not limited. All data is stored in binary format. InMemory principle is used for system performance.

Replication methods

Some of the common reasons for using replication are:
Availability. Replication improves the availability of applications because it provides them with alternative data access options. If one site becomes unavailable, users can continue to query or even update the remaining locations. In other words, replication provides excellent failover protection.
Performance. Replication provides fast, local access to shared data because it balances activity over multiple sites. Some users can access one server while other users access other servers, thereby reducing the load at all servers. Also, users can access data from the replication site that has the lowest access cost, which is typically the site that is geographically closest to them.
Disconnected Computing. A snapshot is a complete or partial copy (replica) of a target master table from a single point in time. Snapshots enable users to work on a subset of a database while disconnected from the central database server. Later, when a connection is established, users can synchronize (refresh) snapshots on demand. When users refresh snapshots, they update the central database with all of their changes, and they receive any changes that may have happened while they were disconnected.
Network Load Reduction. Replication can be used to distribute data over multiple regional locations. Then, applications can access various regional servers instead of accessing one central server. This configuration can reduce network load dramatically.

Mongo DB
The master-slave replication is the oldest mode of replication that MongoDB supports. In the earlier versions of MongoDB, the master-slave replication was used for failover, backup, and read scaling. However, in the new versions, it is replaced by replica sets for most use cases.
MySQL
MySQL supports 2 modes of replication as master-slave and master - master replication types. The first one is used on the base of the same principles described above. MySQL Master-Master replication adds speed and redundancy for active websites. With replication, two separate MySQL servers act as a cluster. Database clustering is particularly useful for high availability website configurations.
Oracle DB
Oracle replication supports the following types of replication environments:
  • Multimaster Replication (Multimaster replication (also called peer-to-peer or n-way replication) allows multiple sites, acting as equal peers, to manage groups of replicated database objects. Each site in a multimaster replication environment is a master site);
  • Snapshot Replication (A snapshot contains a complete or partial copy of a target master table from a single point in time. A snapshot may be read-only or updateable);
  • Multimaster and Snapshot Hybrid Configurations (Multimaster replication and snapshots can be combined in hybrid or "mixed" configurations to meet different application requirements. Mixed configurations can have any number of master sites and multiple snapshot sites for each master).
Credits Blockchain DataBase (DBMS)
The system is a self-sufficient storage node, but it is possible that the system can be represented by two or more repositories with full replication of data among all storage nodes. Synchronization between nodes occurs at the native low level after each block has transferred at the united storage network. This native synchronization method is a priority and more fault tolerant than all other systems since there is no storage master, which must save data firstly and then spend resources on data cloning. Even in case of one of the repositories fails, the network protocol will automatically redistribute the load on other nodes and data will not be lost. If one of the disconnected nodes enters the storage network again, then the process of the missing blocks synchronization will be launched with obtaining the basic information in real time mode.

Transaction concepts

Mongo DB
The transaction functionality introduced by MongoDB supports multi-document ACID features such as transaction operations using the mongo shell, making it the only open source database to combine the speed, flexibility, and power of the document model with ACID guarantees. Through snapshot isolation, transactions provide a consistent view of data, and enforce all-or-nothing execution to maintain data integrity.
MySQL, Oracle DB
MySQL and Oracle DBs support transactions that have the following four standard properties, usually referred to by the acronym ACID:
  • Atomicity ensures that all operations within the work unit are completed successfully; otherwise, the transaction is aborted at the point of failure, and previous operations are rolled back to their former state;
  • Consistency ensures that the database properly changes states upon a successfully committed transaction;
  • Isolation enables transactions to operate independently of and transparent to each other;
  • Durability ensures that the result or effect of a committed transaction persists in case of a system failure.
Credits Blockchain DataBase (DBMS)
The distribution of data is performed by the use of a network protocol based on UDP protocol with transfer confirmation. The first step is block generation. After that all data is converted to basic transfer units like datagram. The formed datagram is transferred to the network where the recipient should confirm data acquisition. This is how the data transaction concept in Credits Blockchain DataBase looks like.

Is it possible to play binary raw PCM audio (no headers) with the standard libraries? (Also what is the most appropriate book for where i am?)

First off, I don't really know anything about python and haven't programmed for years but I did java at uni about 10 years ago and have done actionscript and even some python without knowing what i was doing. I would prefer to learn the language properly rather than stumble through from trying to adapt what i know from other languages. I am thinking of learning python as a way to refresh my knowledge so would like some learning material that goes into depth as to the way python does things and also brushes me up on CS concepts i may have forgotten but doesn't take a laborious "i have no idea what a class or a variable is" approach. I have probably forgotten more than i realise though. So any suggestions on what learning material would suite me best would be helpful too. Ideally something that also focusses on a good IDE and goes into detail about its benefits and how to not be so daunted about them because a lot of the time i always felt kind of daunted by all of the "extra clutter" that eclipse or visual studio seemed to add to projects, while liking the autocomplete etc. In fact i never even really got into the process of habitually using a debugger or profiler rather than my own print statements :$:$
So, suggestions on the best free online book / videos / whatever to go through that suits my background would be great. If you want to ask me some questions to help gauge that then that's fine.
I couldn't really find anything in depth about the standard audio libraries in the "learn python" tutorials, at least all i found was very basic "play an audio file". I suppose my use is atypical. In fact most of the "teach python" stuff i glanced over the contents of didn't seem to have anything about audio playback at all!
The reason why i would like to use standard libraries is that I feel this is better to get an idea of how python works as a whole before i get into additional libraries. Plus i would find it very strange to believe that you cannot playback binary data as audio without an external library but only individual sound files. So i think i must be being stupid and missing something!
Basically, I have a binary archive file with a lot of different raw PCM sound files embedded inside. I know the offsets of each sound file, their sizes, their sample rates (which differ and are unusual, 6500hz for example) and all the info that would be in the WAV file header if they were normal WAV files.
The sound files also have loop regions, so i would like to optionally be able to play from the beginning part of the sound, up to the end loop point then back to the start loop point and when playback is cancelled, finally the end portion of the sound. I'm not sure if this kind of realtime seeking is possible or whether you would have to duplicate the sound file in memory in order to get smooth playback.
The problem is I don't know how to get the standard libraries to play a byte stream of audio or at least playback some audio with a method where I pass parameters of the sample rate, bit depth, PCM format, channels etc.
The winsound library seems to only support the playback of actual sound files rather than raw sound data, so i don't think i can use this? Or does a file in python not necessarily mean a file on disk but could mean something you have created in memory?
wave seems only for reading / creating actual wave files on disk.
Then there is ossaudiodev which I read you are not supposed to use on Windows platforms but instead use winsound. I haven't looked at this one much yet cos it looks a bit scary. From looking now it seems to imply that "writing" to the audio device is used to play the sound. However for some reason it takes then input as a string rather than just a stream of bytes? Wouldn't this be kind of bad for seamless looping if you have to convert everything to strings and then the method just converts it all back to bytes again? Why would it do this :S
So is this possible using the standard libraries? And if not and you need add on audio libraries then how are they implemented if the possibility isn't in python to begin with? Do they have additional code in other languages to add extra functionality?
To be honest I can't even remember about things like buffered reading or non buffered and data streams etc. What i'd really like to be able to do is pass a pointer to the pcm img file / offset in the file along with all of its parameters and then the library plays that. Where as if you are reading the data yourself to a buffer isn't that wasteful and slow cos then you are copying it around rather than reading it raw? Hmm i really need to brush up on concepts but i'm not sure what the concepts i need to know are called!
Thanks if you read all of this, sorry about the length.

Jack of all trades, Master of none tips?

TL;DR: I had no idea that it'd be this long or that it took 4 hours to type(ADD for you :P). Below is last 4 years journey into programming as a profession with a bunch of unlucky breaks along the way. I've developed a wide range(mostly by circumstance rather than choice) of dev/IT skills but none of them feel strong enough for me to land a regular dev/IT job. I lack relevant degree and the roles that I do get pay min wage for me to do a vast amount of things on my own, I'm in my thirties and want to change that, advice?
Adobe AIFlash - ActionScript on mobile platforms Bit of a background. Sunk myself into a bunch of debt studying for something I was interested(art/design related) in but didn't really have much work opportunities in my country at the time. After graduating(2012) and job hunting for about 8 months, my job at the time(4 years in), I got a call from Learning and Development department about a small flash game I made when I started at the company(I had been doing light programming with flash mostly as a hobby since 2004). So they brought me on to do an e-learning project, I had been playing with Starling(GPU accelerated) which made Adobe AIR on mobiles actually viable. Over the span of a year I learnt a bunch and optimized the app pretty well, going as far as to improve the bitmap font renderer to chunk paragraph of texts effectively when scrolling(ok, performance with flash was still pretty poor in some areas even with the GPU :p), I had tried to push heavy text content to be delivered by PDFs but management was against it. That work benefited since I modified the parser to include symbols/images or interactive content within the text document(all loaded externally for easy edits without compilation by staff, built a basic template engine with some pooling). Anyway, this was all under the table and once it was done to the point of proving itself as successful in field tests I was given the boot ha.
Decided if I can't get hired for what I'm qualified in, I'll get out of my job(actual one without the flash dev) and make my hobby into a career. Welp, thanks to Steve Jobs flash dev demand had really gone downhill(probably a good thing for me).
Exploring new territory - Software Testing Got into a short course that was on software testing, it was poorly taught, I was confused about one thing and told I was wrong, mocked by tutor and students, later to find out through leading industry professionals that were regulars in a google group, that I was actually the one who was right.... That course then had some "test" with little information to assist us that you'd expect on the job(couldn't get answers to any basic questions) to test and find bugs on some poor quality foreign website(supposedly actual free/paid work for the tutors clients/friends). It had gotten to a point I saw no value in it, left the course to teach myself online. Passed the ISTQB exam, went to meetup groups, wasn't really digging the career path(job hunt wise, there wasn't much opportunities based on the piece of paper and basic skills I had, most were after mid/senior or some other complimentary skill). During meetups automated testing sounded interesting though. Overall course was not worth 2k it was charging(didn't pay this though as was government funded initiative due to shortage in software testers....right).
Exploring new territory - C# Tried another short course, this one offered free entry with basic programming skills on the basis you'd make payments towards $5k once you secured a job through the education provider. Sounded great, time to learn C#! Again ran into some quality issues, the tutor who was a Senior dev made multiple poor choices that I questioned, I lost interest/faith once we got to the "group" project at the end, I didn't participate beyond reviewing the code by students and advising on where things could be improved. There was a voluntary project for a real company doing a presentation at a TEDx event, it even had a small 3 figure payment on completion. Three other students also volunteered and I was made lead. I had never touched HTML/JS/CSS before beyond viewing source of pages when I was young. The project involved tweening tweets on a big display in realtime and doing some colour transitions(radial gradient BG) based on colour associated to the hashtag paired with the event tag, and a few other features. I had a good idea how to handle that and confident due to my design studies so took the role none of the other devs wanted, assigned two to the backend and another to a simple bootstrap UI for the iPad(feature dropped as they were unable to deliver declining any help I offered). One of the backend devs did a PHP implementation but dropped out for personal reasons halfway through, the other student tried their best and got some assistance via the tutor to reimplement in C# with SQL(we had to support replays with a timescale for speakers to see how their talk was received.), I assisted where I could but was rather swamped on my end with several unexpected issues that cropped up. I ended up pulling an 80 hour week including being flown to the city the event was held at to provide on-call support.... which was required as someones tweet crashed the database!). At one point I had to quickly make a change to the site with no access to a computer nearby, I FTP'd to the webserver and edited the files on my slow 4 year old android phone. Overall great success, but I found myself really enjoying web dev over C# and microsoft technologies. The class all thought I'd be the first to get a job, I was probably one of the last :)
Self teaching myself web development I spent the next year and a half learning as much as I could about web development, unemployed I would often wake up and read until it was time to sleep, trying out some coding(though not as much as I probably should have done), most of the time it was building an understanding of various topics, analysis paralysis with the abundance of choice which was numbing compared to my ActionScript/Flash days and forming opinions to settle on and learn more about based on my own interests, what I believed/understood to be worth the time or was in demand by employers(didn't buy into PHP or AngularJS despite their job demand), I got into Node.JS and ES6. I wanted to play with Vagrant and Docker, graph databases like Neo4j, NoSQL like MongoDB, different frontend frameworks and tools(as well as the ones with node.js like express/koa, gulp, phantomjs, webpack, etc), template engines, mapbox(similar to google maps), ansible/salt and more. I figured I'd start with something small like doing the backend of the TEDx project with NodeJS and Mongo instead.
Job hunting Often when opportunities presented themselves however, I'd completely drop what I'm doing/learning and try to make the most of those(income or job application tests). Most employers through HR or agencies would turn me down due to no related degree, I'd be told I am not passionate or serious about a career as a developer. The growing gap in employment surely wasn't helping either! I had some success with an application/interview spanning over 2 months for a large company with a web department. I had made it down to the final 5 candidates, my technical test didn't pan out the best, I completely understood the answers the ended up wanting but was having difficulty arriving their based on what they were saying and expecting me to say. This was for a position that would take 3 hours to get their via transport with a mandatory 8am start. I figured if I could land the role I'd be able to move nearby in a month or so. Declined but offered an internship for 3 months to develop a dashboard to track metrics and produce a report. I asked some questions such as will I be responsible for the whole development, can I make my own choices on tech or can we leverage existing solutions instead of from scratch, would I have a mentosupervisor that I can get guidance from if needed). I was told if I have to ask questions like that I'm not right for the job and lost my chance at the internship..
Take a break from web studies/job-searching doing Lua game mods and some Python Little disheartened after the long job hunt and study getting no where, I didn't seem able to compete. I took a break from it all and started creating mods for a popular FPS co-op game. I also created a basic level editor earlier that year that imported the game data(JSON) into Maya(3D content program) with Python, then adjust it or import your own additions and export via Python to Lua that my Lua mod would import and allow for custom levels or other fun spawning prefabs. I decided to take on a challenge and do what no one else had luck with, increasing the max amount of players permitted in a networked level. I probably spent far too much time on that, got something tangible by December, and later in 2016 spent all 4 days of my easter weekend finishing it up for release, it was very popular within the community. Guides, discussions and youtube video's appeared for a while....but this work didn't seem like it'd help with securing a job in where I had put my efforts.
Transitioned from Windows to Linux full time After new years, my laptop running windows 8.1 wouldn't boot, the bootloader corrupted. Turns out it was due to fastboot feature having a random chance to cause that, I spent about 2 days trying to troubleshoot it with my phone browser. The solutions I came across were of no help, I booted into a live CD of linux and backed up what files I could to an external drive. Might as well get back into linux I thought so time to install Ubuntu and see what's changed since 2008. Lots of fun problems to solve, from installers with UEFI compatibility issues(had to learn to change this in BIOS), to installers giving me a black screen because my GTX960m didn't yet have proper support in Nouveau. Not long in I learn about QEMU/KVM for virtualizing Windows on top of linux with near native performance (93-98%) with full access to the GPU via passthrough. Sounds fun, so I learn a bunch and write notes, but there is quite a bit of difficulty following the various sources where some information is useful but others not, decide I might as well convert my notes into a decent markdown blogpost to help others out. By the end of it I had switched to Arch Linux and learnt that despite all other hardware meeting requirements, the mobile GPU writes to the Intel iGPU framebuffer. Accomplishing this at the time was not going to happen :( Continued use of linux especially with Arch involved quite a bit of maintenance and learning.
4 years since initial graduation got my first official dev job at a startup The guy I developed the TEDx project for reached out to me offering work at his Startup. Hell yeah a job, my bank account will finally see something positive :) Unfortunately it wasn't doing web development, but there were two devs working there already and I get paid to code fun IoT/home automation project stuff! Got a computer purchased at local store for me to put together and use that very day. Set it up to run Arch like I have at home, was comfortable in it now and it seemed pretty good for doing dev work on. Those two other devs didn't stick around for long, one was still doing CompSci at uni, they had been working on a Xamarin app to control the various devices in the office with, but kept running into bizarre issues. I didn't know Xamarin or C# well but pitched in where I could, some problems that troubled him were a breeze for me to solve. The other one was a recent graduate doing web development on contract, "cool!" I thought. Unfortunately neither knew how to use git, or familiar with Agile practices, nor cared much for documentation.. I was confused why the web developer used plain CSS and jQuery with all their code in a single JS file. Their HTML was based off some bootstrap template with heavy copy/paste instead of a templated languaged that would avoid the DRYness....little did I know I'd have to later do some maintenance on this without being authorized to fix it since it was functionally working to management and not worth time to refactor for future maintenance work.
Saved company a bunch of money While working there, I learnt a proprietary solution we were using, wrote documentation for it for future developers, multiple times I tried to communicate problems with that vendors software and better alternatives available while being told "deal with it, it's the best in the industry"(without any backing statistics/tests). It wasn't until the issues become glaringly obvious and the high costs to go forward with it(we were on an evaluation license) that management listened to the voice of reason. I did some research so I could back up my claims and presented a very popular and actively developed plus sponsored open source project. I spent time getting familiar with it and how to set it up, what drawbacks/limitations might exist(some features needed work but I believed I could contribute what was needed to get it on par), documenting and being sure that it was a solid replacement among the many other benefits it had going for it over the proprietary vendor solution.
Making tech choices On top of that, I picked up React-Native and Redux which was great to work with using ES6, as a solo developer with what I assume was not an ordinary workload being able to share the same codebase for both iOS and Android(plus any other supported platforms) was a great boon, the performance and dev features/speed were great compared to my other options. The choice also mixed great with my NodeJS background I had been building up prior to the job. I felt I made the right choice, setup some backend services to communicate with the larger open source project with our own additions over websockets to the mobile app. I designed the MVP app similar to my e-learning app from previous work but using JSON instead of YAML, and the JSON was generated/cached based on DB queries. The design gave a modulaflexible UI that adapted between phone and tablet.
Getting familiar with embedded IoT dev with C After that we had a business opportunity to pursue. An electronics engineer reverse engineered some products communication protocol, providing serial connection details and hex codes. It was my job to put together some hardware(Arduino) that would eavesdrop on that communication to the devices touchpad controller and allow us to control the device via the Arduino. I enjoyed learning about some protocols like InfraRed in an earlier project but this was a step up for me, I had never worked with C and struggled with the lack of features I take for granted with scripting/dynamic languages. Parsing the binary/hex output into packets and verifying/identifying them and responding with the correct timing was the biggest hurdle for me. I only had one UART serial connection to work with, having to manually switch between listen/send, with limited buffer for the bytes as well as not blocking the device from updating it's controller and keeping that controller responsive while still being able to inject our own instructions as if we were the controller or device providing updates. Debugging I had no idea how to go about, this was hardware, not what I'm used to where I have breakpoints in code and can view the current state. I did naive debugging with text logging via serial, but this was a bad idea since processing that affected timing causing more bugs! :D It was semi viable in some situations as long as the string was minimal, error codes instead of descriptions or long values.
Feelings of success I got that embedded IoT project to work as we wanted in the end, being controlled by the NodeJS server or mobile phone app, we demo'd the product to the company that owns/sells the device product and they loved it and were amazed at what we achieved. This was a client with big money and international business. I know my code wasn't great but I learnt this and pulled it off in a reasonably short time, I felt proud of this milestone, a company like that being so impressed and seeing value in what I had done almost entirely by myself(didn't have the reverse engineering chops yet). So this was going to go ahead, I enjoyed the project and wanted to learn more so I read up a bunch on MCUs and SBCs, sensors and the like to get a good feel what is out there, what we could do with them, flexible designs for a product so we could provide a similar service for other companies. Management wasn't too happy with their sole developer being distracted by such education efforts and wanted me to focus on other tasks(I did a bunch of this after work in spare time as it really interested me, side note I have a problem where I get rather consumed with what I work on/learn, I'll chalk it up to my ADD). I had done my job creating the MVP, negotiations were to go ahead, so I'm moved back to the core product.
Craving to learn more Management wants to begin beta testing on some hardware they're ordering(small headless servers), anyone(company members only at present) beta testing the product will have to fork out a few hundred for this themselves. I state we could totally test on considerably cheaper hardware with SBCs like Pi's, CHIP($9) or Pine64($29) for example...get the usual no stay out of it. Week or so later hardware arrives.
Linux, filesystems, automation and network installs My next task is to install an OS onto these machines that have no monitor output or keyboard/mouse. Automated PXE install(never actually done it before) sounds good, problem is the network availability from these machines were unreliable on boot. Ran into a few issues, but after learning about PXE(which turned out not to be viable), I came across iPXE. We got a new batch of machines, these newer models BIOS didn't support iPXE like the older ones....burned iPXE image to USB, got a serial console setup and chainloaded the kernel and initial ramdisk over an http server via ipxe script. Had issues with Debian/preseed/drivers but openSUSE went pretty well(planned to later use AutoYast with Ansible to automate the whole thing and get it all in git for traceability). BTRFS on a small SSD though(openSUSE default partition) wasn't a good idea as I soon found myself running out of space, thankfully I had been reading up on the various filesystems with pros/cons prior, especially on BTRFS knowing that was the default and how it's quite different from the usual ones(read about it often on news blogs I follow for years). Dealt with the issue but had some other problems that seemed BTRFS specific with Docker(deploying projects with Docker for the benefits it brings), decided initially I'll stick to what I'm most familiar with EXT4 and repartitioned. Documented, investigated, filed issues along the way.
Burnout, "developers are a dime a dozen", am I cut out for this professionally During that job I had stressed myself into a burnout, I've left out many other things especially on those that I looked into heavily but didn't quite get time to implement, such as CI/CD systems for mobile apps(all planned out and decided on), dev machines(zsh with dot files and package list to install, arch and osx, mostly planned out in anticipation for new devs we were going to bring on a while back), additional projects and protocols to be clued up on, project management processes/workflow(again for new devs that didn't end up happening). I felt this was stretching myself very thin, that I wasn't getting the opportunity to grow in any particularly area for my career, I was okay in various areas and understood things well, but my coding was not to the quality/speed I'd like, I was forgetting things that I'd have to relearn. I complained to management at one point I felt this was unrealistic to expect a developer to cover so many areas(web dev, mobile dev, embedded, sysadmin/devop, design/tech decisions(architecture?), etc) as common place, and task them to frequently switch between these areas/contexts. I was told "Developers are a dime a dozen". I disagreed that anyone sane would be doing all these things for minimum wage(I did like the freedom of development choices and growing my skills, no one else wanted to hire me to code, what's a bit of sanity? ), it was becoming a problem, I didn't sign up for all of this, and thought I'd finally have other developers to work with, maybe even learn from.
Resignation. Where to now I resigned from that job after a meeting revealed how little I was valued(among other things), despite my honest belief that without my efforts they would not have been able to afford the talent needed to achieve where they are today. But now I'm back to the job hunt with an obvious lack of good reference from the company I spent half a year at. I feel I have a broad range of skills, not many employers will be interested as they advertise for more honed skillsets... I might be perfect for a startup, but I'm not fond of the chances going through previous experiences again. Do I try to promote my range of dev/IT skills or do I spend time unemployed until I'm good enough for a junior role in one skillset such as web dev? I'm in my thirties now and would like to earn more than minimum wage doing what I love.

Death Rings of Jupiter: A Loose Postmortem

This is a long post ... but if you're up for it, here it is:
When Al told me that he’d been secretly working on a game called Death Rings of Jupiter for three years and it was going on sale in a month on Steam, my first thought was, “You sneaky bastard.” Quickly followed by, “You’re amazing! You did it!”.
Up until then, making games had been a regular staple of our conversation, discussing our favourite childhood memories, stand-out games, mechanics we loved and everything else that comes naturally to two nerdly fellows. I understood immediately why he’d kept quiet about it.
Making a game is as much an emotional experience as a technical one.
Now that it’s done, up and ready, Al confessed that he was still sitting in front of his machine at night, staring at the screen, fingers still phantom-coding. So I offered to perform that service which always seems so sadly optional, the exit interview. The post-mortem on a finished project
What follows is a loose conversation we had over the phone using a simple structure to get a sense of the what, whys and hows of it all. It is my hope that sharing this will raise awareness of the game itself and free up Al’s talent to start thinking about the next project.
Steam Page: http://store.steampowered.com/app/691620/Death_Rings_of_Jupite Game Trailer: https://www.youtube.com/watch?v=gytOUueHbX0 Home: http://wirehead.com.au/droj.htm
Ulter: Hi Al, welcome to your project post-mortem. Let’s start by getting a sense of people and skills, so tell me a bit about yourself and what skills you brought into the project …
Al: Oh … huh. Well it was just me. I guess I started out playing a lot of music. Lots of bands. I spent a bit of time in a band called Operation Lager, teaching myself recording and production skills. I really loved the technical aspects of making music. So … yeah.
A bunch of music and just fooling around with games dev on top of that. I’m not a programmer or an artist, but I did a bit of Visual Basic in high school and a TAFE course in Digital Arts and Media. From there I learnt a bit of Flash and Actionscript … so I guess I came into it with that more audio-visual background and decent Actionscript skills.
Ulter: Great! Tell me about your influences. What resonated with you as a kid that you couldn’t shake that you brought to this project.
Al: Yeah, ok ... I had an Amiga 500 back in the day. My dad helped me learn a bit of AMOS (the Amiga version of BASIC) and I just loved it. I loved the Amiga! It had full-colour! And the sound! When I got a modem, before the internet as we know it, i used to connect to public BBS' and download Public Domain games , freeware was called PD in the amiga days. Finding and playing all those games made by hobbyists was inspiring me. Those early efforts by the 1990s version of indie game developers was a huge influence, for sure.
Of actual games ... I had Sensible Soccer, Worms … those 90s era games. I remember wishing for Doom, but I had to settle for the clones. Eventually I moved on to games like Duke Nukem and Quake. Games I could play with my friends because LAN parties were starting to become a thing. I remember carting around like six boxes of floppy disks.
I did get seriously into turn-based tactical games like X-Com and Laser Squad but one of my all-time favourites is still Elite. I loved that feeling of vast universes filled with pirates and space stations and just exploring and trading.
Lately, and it shows in DROJ, I’ve been playing a lot of Minecraft. I’m not a huge fan of the resource grind, but it’s a great example of how much you can do with simpler graphics.
Ulter: Yeah, you nailed that. Next question! How many games have you worked on over the years? How many did you finish?
Al: Geez, probably between 10 to 12 games. Just all over the shop, but I reckon I finished five or so. They’re on my website. They’re mostly in Flash .. so I guess I’ve got a few finished Flash games online.
Ulter: Cool. Alrighty, let’s start on Death Rings. I could just copy and paste the product blurb, but tell me about it anyways.
Al: Oh ok. I guess, at a basic level, it’s a shooty sort of game. I say Rogue-like bullet hell shooter … but there are so many of those games! There’s so many games in general! I struggle a bit because I’m so conscious of just how much dodgy shit there is out there. I feel like I have to say, “It’s special, it’s unique.” at the same time as making it seem approachable and familiar.
So … yeah, it’s a shooty sort of game with lots of things on the screen and it’s hard as hell.
Ulter: So what in it are you proud of?
Al: I think I’ve added something special and unique to the genre. Haha. Seriously though, that’s what I think I did with Death Rings. I wanted that retro arcade, bullet-hell feel with some of the elements I love from other games and I think I got it. I’m really proud that I added something to that.
I’m also really proud of some of the technical skills I developed. Coming from an audio-visual background didn’t really prepare me for rolling up my sleeves and getting into performance tuning and analysis.
Actually understanding the technical aspects well enough to fix issues myself, things like sync-ing framerates to gameplay when you’ve got tons of aliens on screen and they’re trying to kill you, or just working out a data structure for a save file and realizing that I just hit a real technical block in the language … this game really pushed me.
Ulter: What mechanics did you want to explore with it?
Al: Definitely open-world mechanics in the beginning. I loved that procedurally generated open world feel. I spent a bunch of time working with that one, trying to find that sweet spot where the parameters created something relevant, but also had that built-in novelty and uniqueness.
Ulter: Unfairness …
Al: Yeah, absolutely. Sometimes you just get unlucky. It was possible for an asteroid to form as a giant cave and the aliens would just spawn inside of it. So cracking it open released a death swarm. It’s just one of those moments where you think, “Oh, that’s unfair. That’s hard.” but you have that choice as a designer.
Finding that sweet spot where it’s ok to be unfair to the player. If you’re always fair you might as well just script it everything out … the catastrophes are just another set-piece instead of a genuine emotional response that everyone has when the dice don’t roll our way and you never get that rare, rare feeling of having overcome something stacked against you. If the game isn’t unfair at times, you’ll never get that opportunity to win at an unfair situation. Ulter: That’s actually pretty interesting, it makes me feel a bit uneasy thinking about it. Like the little monkey accountant in my midbrain is already flipping tables and demanding justice. But that’s ok. That guy can use a little shaking up. So … what did you do with this stuff?
Al: Well .. it turned out that actually creating a save game of a universe in Actionscript wasn’t technically that possible. I could do it, but it just created massive load and save times. It wasn’t feasible. So the game started off as this huge map but over time I created islands, little patches of chaos within that larger framework.
So I could have the best of both worlds. I could have that procedurally generated feel, but I could control the parameters at a macro-level. When I made that decision, I was able to include tailored boss fights, break the map up by difficulty levels … I made spreadsheets to model parameters and work out how the different sections were likely to work.
I really wanted resource acquisition in the game, but I didn’t want it to be grindy. I wanted the focus to be on the action and exploration. So, actually, I did spend a lot of time initially really getting into the action elements .. really getting into collision detection, physics and just generally trying to work out how to get heaps of things on screen at the same time.
I changed up the resource acquisition to become levelling up, even though I had originally hoped there would be more trading elements in the game.
Now that I think about it, I spent a lot of time in the early stages just focusing on the core game-play. Just shooting things and making that as impeccable as possible, as refined as I could make it. I think it shows in the outcome because it stayed true even when everything else mutated.
Ulter: Sweet … and now, tell me about the steam store experience
Al: Simple ... well, a bit overwhelming at first … the application was easy. I just went through the indie channels, they really make it easy. Too easy, maybe, but setting up a store page and getting that early feedback was really helpful. I was a bit challenged by the graphic design elements, like having to supply a bunch of different image sizes and so on … there were a lot. Marketing is something I’m a bit shy about, I guess.
Ulter: What's next in the way of new features and content for Death Rings?
Al: Depends on if people are interested, but I’m not sure. I don’t think there’s anything wrong with just putting out a finished game without expectation of continual updates and new content. It can just be a game, by itself. You can play it, put it down, come back to it. It’ll be the same. You can go on forever adding shit and I’ve got other ideas I’d like to work on.
Ulter: Yeah. Fair enough. Alrighty, next question! When did you actually start this project?
Al: Hah, yeah. Three years ago. December 2014 ... It was Christmas and I had a bit of time off work. I was getting over the game I’d been working on and I had the idea and got started. Hang on a sec … I’ll just pull up the commit history…
Ulter: Do it, there’s only a few more questions.
Al: Hah, I haven't actually sat down and looked at it in a while. Yeah. first commit was that January 2015 and I released it December 2017. Three years in development.
Ulter: Since you’ve got in front of you, can you tell me what the longest gap in development time, or if you can see some sort of work cycle …
Al: Huh. I feel like there were long gaps and big sprints … but looking at the history, it sort of looks like I worked pretty consistently over that period. Roughly 200 or so commits … looks like I worked on it on average around 12 hours a week, but that changed from week to week. Weird. I feel like I just quit the project so many times … like I just walked away from it and didn’t come back for months … but that only happened once. The longest gap in development time was 2 months over that 3 year period. Wow.
Ulter: That’s actually really cool, Al. But my anxious readers demand to know, how did you finance it?
Al: Oh I work full-time. I spent maybe 3-4 hours a couple of nights a week just working on it. So in regular game dev style, this game was really powered by coffee and a day job.
Ulter: Almost there, Al. How did you keep your motivation?
Al: Umm … I started enjoying the game. I love bullet-hell shooters with a ton of shit on screen trying to kill you. It was fun to play .. but I guess, really, I just pushed through it. Starting is the hardest part, if I just started, then an hour later I’d look up and I’d have done an hour of work. I could go do something else.
But often, once I’d jumped that getting-started hurdle, hours would disappear and it’d be time for bed and another day at work.
Ulter: It’s a classic, but I also meant how did you handle it when it was just you sitting there, working away, and you realised that something just wasn’t going to work. You were going to have to change it up … how did you keep your motivation when that happened?
Al: Oh yeah … right. Well, I just gave myself a bit of space to sit with it. Think it through. I didn’t force myself to make a choice. I made up spreadsheets and tools to model different things, which made it easy to get a sense of where I was going with a change. Then once I’d gotten a bit of confidence with it, I’d knock up a quick experiment, a proto-type to have a better look at the mechanics of it.
I guess I kind of gave myself space to think and experiment … it took years to write, so why not spend a bit of time just exploring.
Ulter: Awesome. Last question! How would you rate your technical creative, artistic, audio, background coming out of the project?
Al: Definitely performance tuning. Understanding that multi-threaded architecture in software, how randomness plays out. I had to learn a bit of SQL … but I think the biggest thing was how to polish a game. How to actually package it up for release and make that release a solid one. Like everything just being right, tested, running perfectly.
That level of polish and what it takes to really achieve something that doesn’t have a bunch of frayed edges and loose threads. Putting out an obfuscated binary that ran well and the gameplay was tight. That packaging and polishing was easily where I grew the most in the project.
Ulter: Thanks Al! I’m really happy and excited for you. Thanks for sharing a bit about the project and letting me participate in a retrospective of the project with you.
Thanks for reading this! I hope you found it a bit interesting. I find Al to be pretty inspiring, so it's good to share.
