Easy integration capabilities.

Fast to implement codes.

Multiple functional frameworks.

Python helps develop flawless mobile and web applications that accelerate the ROI of commercial projects, making it an ideal language for developing web applications.

Keep Your Data Safe and Secure

What makes Python safe is that it hides the source code of your program from direct viewing, which makes it harder for hackers to breach the data. This invariably provides enhanced security to your applications and keeps them safe from external attacks.

Free Availability

Python is free and remains available at no cost in the future – it means its expansion set of supporting tools, libraries, and modules is completely free. Many of its popular IDEs – integrated development environments such as PyDev with Eclipse, PTVS, and Spyder Python are available for free download.

Within Budget

When it comes to building a product, preference and expertise may boil down your choice for any language. Python development can be the best choice for your business if you are on a budget. It is an ideal option for startups and bootstrappers because of its quick development and less coding next to C, PHP, Java, and others.

IoT Friendly

In the era of IoT (Internet of things), Python has brought countless opportunities for Python programmers. Platforms like Raspberry Pi allow developers to build their own exciting devices like radios, phones, cameras, and even games through Python with ease.

In recent years, Python has also emerged as a dominant language in the field of artificial intelligence and machine learning. Python's strong support for data analysis and visualization, coupled with libraries like TensorFlow, PyTorch, and scikit-learn, have made it a go-to choice for building machine learning models and deep learning neural networks.

After 30 years of its inception, Python still dominates the web development market because of its brilliant modules, libraries, frameworks, and many other capabilities.

Linguistics Jobs: Interview with a Software Engineer

Like today’s interviewee, Brooke Lynne Weaver, I worked through my undergrad degree. While not everybody is lucky enough to be able to do both study and work, it can be a useful way to develop skills beyond those in the classroom. I now use my coffee making skills only for self-caffeination, but cafe life taught me a lot about task prioritising and staying upbeat under pressure. Brooke used her work experience to move into Software Engineering, and uses her linguistics in her approach to her work, and her everyday life. Brooke is also on Twitter (@Milayou).

What did you study at university?

My degree is in English Language (Linguistics with an emphasis on the English language) from Brigham Young University in Utah, U.S.A. Basically, when we covered morphology, syntax, phonetics, phonology, sociolinguistics etc. it mostly focused on those applications in English, with some examples and work from other world languages. I also took a couple computer science classes and worked as a web developer while in school.

What is your job?

I'm a software engineer. Right now my job title is Platform Engineer, and at my last job it was Platform Architecture Engineer. I write code based on the needs of my company, which generally involves understanding the task you need the computer to perform autonomously, and doing a bunch of Googling to remind yourself (or learn) how to tell it to do that. You run the code, look for certain things to happen, tweak the code, run it again, look for different results, tweak it again, run it again etc. The ask from the company is generally as specific as humans tend to be, which is not nearly as specific as machines tend to be; you have to be on the lookout for instructions that should be given that were never expressly asked for by the company in order for everything to run smoothly. Our stack is mostly written in Python 2.7 but we're moving to Go, and the project I just finished up has parts written in both. It's really satisfying when you've finally communicated your message properly to the machine and it behaves accordingly.

I work for Vivint.SmartHome right now, doing home automation. I help the Vivint centralized system interact with peoples' homes and phones all over North America. When someone pulls up their Vivint app on their phone, it requests data from our platform. When they want to make changes to their smart home system, it interacts with our platform. Recently I've been helping migrate our Nest integration from using the (now deprecated) Works With Nest API to the new Google Home/Assistant API (a transition Google recently made public).

How does your linguistics training help you in your job?

I like to tell myself I went into translation, just between human and machine languages rather than from one human language to another. The things I learned studying linguistics help me in less obvious ways.

Knowing how flexible semantics is and how language changes so much across time and space, I feel like I'm a much better communicator than I was when I first started college. I'm a lot more flexible in interpretations and I care a lot more about getting to the root of what a person is trying to communicate, rather than what words they chose and what those words mean to me specifically. Communication is a pretty important part of writing software, because you're almost always trying to realize the ideas of other people. Knowing how to be confident you're on the same page as the people requesting your work is critical.

Linguistics also gave me a much better understanding for how important context is. I leave comments everywhere it makes sense to in order to help future engineers understand why I did certain things, which puts them in a better position to understand what to change down the line. It's very common to come across some code written a few years back that seems to make no sense at all (or seems like a bad way to do something), and if someone left a comment explaining why they wrote it that way at that time, you can better decide whether to leave it or in what ways to change it. The comment might say "Here's the current state of affairs and we need to do this weird thing to avoid this problem" and now, several years later, that problem is irrelevant or the current state of affairs has drastically changed; you might not need to do that thing in such a weird way anymore. You can then feel more confident about making your change. Or, maybe the state of affairs has not changed or the problem still exists and still needs to be avoided; you now have really important context and that weird thing might actually look logical now, or you know how to change it while still avoiding the problem it was originally trying to avoid. As an example, earlier this year I implemented a library I wasn't very familiar with in a pretty short amount of time. I left a comment explaining that if someone else was more comfortable with the library, they should feel free to rewrite it in a more idiomatic way; I explained what parts of it I wrote somewhat poorly due to lack of time and familiarity (something like "I know you should be able to do it like A, but I couldn't figure out how to get A to work so I did B instead which isn't as good but gives an acceptable result. It's not deliberately done this way for any other reason, so if you know how to do A, please change it."). A lot of times we try to change legacy code as little as possible, for fear of unknown downstream affects, because we weren't there when it was written and don't know why it was done the way it was; I hope by leaving context comments I can help future engineers feel more comfortable keeping the codebase clean and efficient.

Do you have any advice you wish someone had given to you about linguistics/careers/university?

I have some advice I was given that I think is valuable. I had a really hard time choosing a major field of study because I was interested in almost everything. A counselor reminded me that you can still have any hobby you like, regardless of what you study at university. I was afraid that by choosing something I was cutting myself off from other things, but that's not actually true. I still love playing the piano even though I didn't go into music, and I still love math even though I didn't go into mathematics.

Also, my university offered a lot of student jobs. These were jobs that were only allowed to be worked by students, which meant the barrier to entry was fairly low. I don't know if other universities offer student on-campus jobs, but if they do, I very much recommend them. I worked student jobs the entire time I was at school, which meant I graduated with seven years of work experience. Yes, it took me seven years to get my bachelor degree, but that work experience meant I had no trouble getting jobs after (and even before) I graduated. That said, maintaining a job while going to school is an awful lot of work and it's not the right path for everyone; everyone's situation is different, this just worked out well for me.

Any other thoughts or comments?

Besides how linguistics training helps me at work, it's made me a FAR better human. I'm a reformed pedant. I was really condescending and had a bit of a superiority complex about language when I was young. I was all about correcting and fixing people and being exasperated when people wrote or said things "wrong." Studying linguistics has given me a LOT of empathy and understanding and freed me from most of my pet peeves. My perspective on language and communication is so different now. I feel free. It's a far pleasanter experience to put your energy toward really understanding and being understood by a person than on looking down on people and discrediting their thoughts because they don't know how some dude in the 19th century wanted a part of English to work that doesn't even make sense anyway. I think a lot of unnecessary conflict comes from different groups of people having different understandings of certain words, and fighting over the definition of the word rather than over the real human issue at the heart of the debate. It would be nice if we taught language a little differently in schools, so more people could be aware of how semantic drift occurs and how different people can use the same word to mean different things, and that language change is okay and actually beautiful.

The Classic API is a great alternative when the feature you intend to leverage isnt yet supported in the Jamf Pro API. Naduald shows a few examples in detail, including how to: list all computers, list computers with a specific name, handle policies with logout triggers, review all Self Service descriptions and remove computers that haven’t checked in since the previous year. Generally speaking, Jamf recommends the use of the Jamf Pro API, given that the feature or functionality youre looking to leverage is supported. Topher Naduald covers jctl Functions: a simple tool to perform actions that would take many actions to perform such as GUI-based searches modifying policies, scopes, or computer groups and updating patch policies. This easily-adapted tool is available on PyPi. Depending on database restrictions and performance it may. Log retention in Jamf Pro is set under System Settings > Log Flushing.

Generally speaking, Jamf recommends the use of the Jamf Pro API, given that the feature or functionality you're looking to leverage is supported. Use these at your own risk, as future versions of Jamf Pro will likely require updates to your tools or applications, to continue using these endpoints. While endpoints in this preview state are functional, there will likely be changes to them before they're released as v1. In addition to endpoint versioning, the Jamf Pro API supports a preview mode, which allows consumers to get a sneak peek at endpoints that are in the process of being released. Now that we understand a little of the history and have a basic overview of some fundamentals of each API, let's explore some of the finer details. Jamf Pro Classic API is the Enterprise Mobility Management tool that delivers unified endpoint management for Apple devices.

Annotated edition of May 17 Week in Ethereum News

As noted last week, I’ve started to think of this as the “Eth holder, but doesn’t work in the industry” edition, so we kick it off with the high-level things I’d read beyond just what you can read.  So, for example, Gnosis/OpenEthereum is picking up the Parity client, but you can see that without me highlighting it.

So here’s my highlight of high-level things for Eth holders.

Some interesting findings in ConsenSys’s eth2 staking survey

Visa patent shows they are building on Ethereum

Building on ethtrader’s DONUT, Reddit unveils community points for r/fortniteBR and r/cryptocurrency subreddits. At the moment, 9000 wallets created for fortnite and just 2100 for r/cryptocurrency. Currently on Rinkeby testnet with plans to move to mainnet.

JPMorganChase decides to bank Coinbase and Gemini

ErisX launches ETH futures, physically delivered, monthly and quarterly contracts

dydx’s BTC/USDC perpetual with 10x leverage is open to the public

This BTC/USDC perpetual matters because the crypto market has been overtaken by YOLO gambling on centralized exchanges that probably trade against you as they know liquidation points and no one else does.   Not a surprise, dydx’s founder says this is already the #1 most traded DeFi.   Centralized exchanges get hacked all the time - not your keys not your crypto.  DeFi is an improvement.

We finally have Eth futures!  And they’re physically delivered, which is good.  Though physical delivery requirements can lead to strange consequences (eg,negative price of oil last month!), it keeps traders honest and moors the price to the actual asset.

JPMorganChase finally banking some crypto clients is an important step for the space.

Reddit is testing letting subreddits govern themselves and pay for things using an Eth token.  Very cool

Visa patented their method of digitizing dollars on Eth at the same time that their chairman said at a conference that “digital currencies could be additive to the payments ecosystem” and that they “supported” them.

In September 2018, the same Visa chairman said that “[blockchain] isn’t really at its core, for us, a good technology.”

It’s interesting that even as the crypto market continued to wane, Visa realized they needed to try to get ahead of the curve.   Crypto isn’t dead.

Eth1

Geth v1.9.14 – unindex and save disk space

OpenEthereum v3. Formerly the Parity client. Support for eth/64, breaking database changes to save disk space. Deprecating light client, auto updater, and private transactions

cross-client consensus tests v7

Latest core devs call. Beiko’s notes from the call, largely around EIPs for next hard fork, eg: 2315 (evm subroutines), 2537 (precompile for curve in eth2), 2046 (reduce gas for static calls to precompiles) and 2565 (repricing the 198 precompile)

EVM+384 bit arithmetic as an alternative to EIP2537’s precompile

Discussion of a second method for resource accounting alongside gas: oil from Suhabe Bugrara, separately formulated as karma from Martin Swende. Or a counterproposal from Vitalik: per account gas limits

The case for Eth-collateralized tokenized gas at the protocol level

So the first real release of the fka Parity client.  Very cool, client diversity is important and to my knowledge there are no large scale miners running anything but the Go and Rust clients, so this is important.

What’s up with the “second method of resource accounting alongside gas?”  The idea is that stateless Eth will need a substantially different gas schedule for block witnesses, yet we don’t want to break existing contracts.  We want backward compatibility without overly complicating the dev experience.  Not an easy problem, hence the debate about the best way to do it.

Meanwhile there’s a bit of a debate about some of what goes into the next hard fork.  Relatively normal stuff, some folks think we should stop doing all these precompiles (eg, bit arithmetic proposal), others think we should only do the general precompile EIP

Eth2

Latest what’s new in eth2, featuring Ben’s thoughts on timelines

Latest eth2 implementer call. Notes from Ben and Mamy, targeting June for the multi-client testnet

Schlesi testnet: Teku is fully participating and Nimbus is almost fully syncing, though there was a chain split this weekend

Proof of custody through occasional checks and slashing

Stethoscope: networking test suite

Idea from Justin Drake on putting price feed oracles in eth2 via validators, and a counter-proposal from Vitalik Buterin

The Schlesi testnet went down, but overall it has been quite stable.  Nothing terribly unexpected for a testnet, and Lodestar will soon be the 5th client to join up.  Slow and steady progress.

Price feed oracles got quite a bit of pushback, I think some of this is because stablecoins are having their second renaissance - something I’ll touch on later.

Proof of custody (ie, that you as a validator hold the data you say you do) through a Truebit-like game: to prevent lazy attestations, the protocol will guarantee false things, and if validators don’t point it out, then they get slashed.  

Layer2

What are the true finality guarantees of state channels? Depends on liveness of layer 1 chain

We often say that state channels offer “instant finality” but this is a bit of a shorthand to say that it offers “instant finality” assuming that the underlying basechain has “liveness” (which is just blockchain-speak for “is producing blocks”)

This newsletter is made possible by Trail of Bits!

Trail of Bits recently reported and fixed 12 security issues in projects across Ethereum, some of them critical. Read more about what they were and how they found them in Bug Hunting with Crytic.

Stuff for developers

OpenZeppelin Contracts v3, but modified to be safe for upgrades

Mainnet testing with your own node using Brownie

headlong: ABI v2 and RLP for the JVM

EthPM v3 – spec for v3 of Eth package manager is in last call

12 bugs found by Trail of Bits’ Crytic tool using 90+ detectors

Verifiable randomness on-chain using the Chainlink VRF

Austin’s eth.build explainer vid is great.  Truly recommended - as a community we should be trying to get this in front of many devs as possible.   

How long until someone wins a hackathon with eth.build + oneclickdapp or dapphero?   Seems possible.

Chainlink VRF seems quite cool; PoolTogether is already integrating it.

Brave releases Mjolnir tool for easy deploying and benchmarking permissioned Eth chains

Brave is going to move their token to a separate chain, presumably with a bridge.  Doesn’t seem like terrible news to me, if you have a small amount of BAT, you don’t need a strong censorship-resistance guarantee.

Application layer

Building on ethtrader’s DONUT, Reddit unveils community points for r/fortniteBR and r/cryptocurrency subreddits. At the moment, 9000 wallets created for fortnite and just 2100 for r/cryptocurrency. Currently on Rinkeby testnet with plans to move to mainnet.

Utah County (Provo) in Utah offering marriage licenses certified with the hash on Eth mainnet

dydx’s BTC/USDC perpetual with 10x leverage is open to the public, and compares centralized and decentralized perpetual markets

Lots of cool stuff, some of which touched on above.   Utah County is not the first local government to do something like this, but as far as I could tell, it was new.   That must have been a hard sale with the crypto hope at a relative nadir.   Amusingly their site was not https (not that I should judge, I’ve been lazy about that myself, usually do to my cheapness in finding hosts...ahem Tumblr)

Brave growth keeps going.  It really is a superior product, it always surprises me that there are some in crypto who doesn’t use it.

One interesting trend is that we’re having a bit of a renaissance in projects trying to compete with Maker.  Of course Synthetix has had quite a bit of success, though previous rounds contained some laughable attempts (Basecoin).   Stablecoins have a large design space with lots of risks to tradeoff.  I think the new wave of stablecoin designs has some interesting ideas.  I think there’s plenty of space for more people to be successful, though I think plenty of folks are underrrating how hard it will be to compete with Maker.

Overall this felt like a good week for the app layer section, and my usual arbitrary “how much is DeFi? metric comes in at 6/10

Now ~2300 WBTC on Eth versus 900 BTC on Lightning

RAC’s $TAPE launched on Zora and went from $20 to $1000. $TAPE is a token redeemable for a special edition cassette of RAC’s latest album. Interesting new model for artists to capture value

I guess “days, not weeks” dies as an Ethereum meme?   Or maybe it’s like wooks and TwoWeeks, and it will live forever.

(if you don’t catch the reference, there before Eth shipped in july 2015, there was 18 months of Bitcoiners claiming that it was vaporware that was impossible and would never ship, and the eternal answer was always that the ship date was “two weeks” away....which became “two wooks” because the internet is wonderfully weird).

Meanwhile BTC keeps migrating to ETH, as the Bitcoin chain is too limited and fundamentally unsustainable so if you want to do anything with your orange memecoin, then you have to use Ethereum.

Loved seeing RAC’s $TAPE do well.  While critics say this is gimmicky and perhaps not replicable, I actually tend to think the opposite.  Many artists have huge fans who would pay insane amounts - artists have never done a great job at giving their fans new experiences and capturing value.

Pluralsight: Calling all Python experts! Earn extra cash doing freelance work from home.

Headquarters: Utah URL: http://pluralsight.com/teach

We know what you are thinking: “This sounds too good to be true.” Hate to break it to you, but it’s not. Pluralsight is looking for Python experts who can create projects. Pluralsight projects are text-based tasks that invite learners to download starter code. Learners can complete the tasks one at a time and, at any point, upload their code to Pluralsight for automatic feedback per task based on the results of unit tests. 

Here’s some more good news: Our experts are able to work where and when it’s convenient for them. Midnight in your PJs? Check. Ten in the morning from your favorite coffee shop? You bet. This is a chance to use your knowledge to make some great money through an excellent side gig. You can also build your portfolio and expert status in the Python community.

Reasons to Apply

Rather than just give you a cursory list of all the great reasons to partner with Pluralsight, we thought we’d share a few that might be important to you:

Networking is everything and you will join one powerful network! Become part of an elite community that comprises the top one percent of expert technologists in software development, IT operations, security and other technical fields.

You’ll be a part of something bigger than yourself. Join a revolution that shapes the future of technology. Help us create the creators who will deliver technology that lifts the human condition. Your contributions will help save lives, transform living conditions and deliver new opportunities.

Did we mention that you get to work at your convenience? We know we’ve said it before, but we think it’s a pretty nifty way to earn some dough.

About the Job Interested? We’re looking for technologists with these qualifications:

A strong background in Python (you probably saw that one coming).

Write comprehensive Unit Tests — Projects don’t function without these, and part of the magic of projects is the ability for a learner to test themselves against your requirements and get validation for the skills they’ve been building.

Organize tasks logically — Users engaging in your content will be following along on a step-by-step basis, hoping to validate the skills learned through Pluralsight and many other sources. Your ability to organize the steps needed to complete these projects will be key in helping them find success with as little frustration as possible.

Predict user mistakes — Many of us process data differently, and as a developer you know that coding is no exception. As users work through projects, the error messages provided in your unit tests need to predict as many outcomes as they may create, while getting EVERY example may be hard, you’ll need to be able to predict what a beginner would do given the project.

An internet connection. Our company is global and so is this job.

The Good, the Bad and the Unknown — Bluehost Review In 2019

BlueHost is one of the oldest and most reputable web hosting providers accessible as my review in 2019. This Bluehost evaluation depends strongly on information, as well as on the general experience with their hosting characteristics and customer support.

In short, all Bluehost plans give their clients 24/7 live chat, unlimited bandwidth, and at least 5 email accounts. Similarly to many other web hosting companies, they too offer their users a free domain for the first year. Their plans start from $2.75/mo and include improved security, backups, and SSL certificate. These help keep your website secure and protect.

Overall, their performance was great. Bluehost is obviously at the top with its uptime (99.99 percent) and a quick load time of 0.41ms. Read all of the “Advantage” and “Disadvantage” below:

First of all, we should know about the history of Bluehost.

History of Bluehost?

Most of the individuals who heard about any hosting business probably learned about Bluehost.

Podcasters and internet marketing leaders love to encourage it, but is it a nice thing?

Founded in 2003, Bluehost is a private hosting company owned by Endurance International Group. With its sister hosting HostMonster, FastDomain, and iPage, the group owns almost two million domains. The service specialties are based in Provo, Utah, Bluehost VPS and specialized server hosting plans.

How Good is Bluehost Hosting?

The biggest selling point of Bluehost is, well, their selling point.

Bluehost pricing (beginning at around $2.95) is one of the lowest on the market and comes standard with all the fundamental characteristics that a shared hosting supplier might want.

They are worth comparing against other similar budget hosts as they offer a wide variety of plans with certain niche advantages. You may want to keep an eye out for a few things that our researchers found, however. Uptime and speed are considerably smaller than most rivals (particularly higher-priced competitors) and Bluehost’s customer service is not as helpful as one would have hoped.

General Info & Hosting Overview of Bluehost Review

Let’s see Bluehost Review In 2019

OVERALL RANK: Rated #1 out of 32 web host

speed: 406ms (Average from December 2017 to March 2019)

UPTIME:99.99% (Average from December 2017 to March 2019)

SUPPORT:24/7 Live ChatAPPS: WordPress, Joomla, Drupal, and some website builders

FEATURES: Unmetered bandwidth and storage, email accounts, free domain 1st year hosting

PLANS: Shared, Cloud, VPS, and Dedicated Servers

SITE TRANSFER: Not free pricing:

Starting at $2.75/mo (renews at $7.95/mo)

Why Choose Bluehost?

• Bluehost is awarded #1 for WordPress by WordPress.org since 2005 • Heavy focus on WordPress with WordPress installed by default on all new accounts • Custom-branded cPanel with all of the industry-standard features • Affordable cloud hosting with solid performance/reliability • Optimized plans specifically for WordPress and WooCommerce • Free & paid integrated SSL certificates for eCommerce websites • Personal & direct customer phone support based in the US • Numerous add-ons available, such as G Suite, Spam Experts, SiteLock, etc.

Key Features We Like On Bluehost Hosting

• Default support for PHP, Perl, Python, Ruby/Rails, & MySQL on Apache with the ability to install any other web server extensions required by developers or programming teams. • Fast hardware with SSD storage and real-time analytics that monitor website user traffic. • Immediate provisioning with no need to spend hours installing the OS and setting up the server. • Inclusion of Dedicated IP addresses and cPanel/CentOS license saves money over other companies. • Easily organize, edit, and manage databases directly on the server with Bluehost’s custom-designed database manager.

WHAT WE DON’T LIKE:

• VPS plans max-out at 4 CPU cores & 8 GB RAM, forcing an upgrade to dedicated servers.• Cloud Hosting plans are cheaper and more feature-packed, with higher capacity to support traffic spikes on a scale, while offering comparable hardware allocations, developer instruments, and third-party add-ons. • Configuration settings for sophisticated web page caching & HTML / JavaScript compression may be complicated for inexperienced users and involve live testing on manufacturing locations to be optimized.

What Are The Disadvantage of Bluehost

• Monetizes your site by injecting ads onto the 404 pages (although this can be disabled) • Basic hosting plan only allows you to host 1 website • Weebly site builder is pointless • Average speed & reliability scores from our performance testing on shared hosting plans • Uses MOJO Marketplace which includes a lot of bloatware/upsells • Charges $149 for migrating your existing website over to them • The cost of additional dedicated IP addresses can be expensive • Customer support via email tickets was discontinued • No prorated refund after 30 days

Do We Recommend Bluehost Hosting

yes, we do

Bluehost ranked at or near the top for both uptime and load times for more than a year.

They also provide strong safety help, money-back guarantee, and a lot of user-friendly apps, all for one of the lowest rates in the industry ($2.75/month).

They’re not perfect, however. Renewal prices will occur following the closing of the introductory price. And they pay extra for site migrations, which other hosts throw free of charge.

But overall, for a good value, Bluehost delivers a strong performance.

Building my own rasteriser: part 1 - setting up

For various reasons, I’ve been trying to teach myself about 3D computer graphics lately.

Reading theory is all well and good, but you aren’t going to learn a thing if you don’t actually program anything. Graphics code, which has to be very fast, is often written in C or C++, so it’s time to dust off those C++ skills from uni. After several years coding in much easier languages like Javascript and Python, they’re very dusty skills.

The plan

My first objective is to handle none of the shading side, just the bare bones mathematical aspects of transforming triangles into normalised device coordinates and displaying a 2D image of the points. This doesn’t necessarily need to involve graphics card APIs yet. I will be following this well-explained tutorial from Scratchapixel.

The next goal will be to learn how to send data to OpenGL (or Vulkan!), write simple shaders, and get results out along the lines of less theory-heavy OpenGL tutorials. A reasonable objective here is to have a nice revolving Suzanne or Utah Teapot with a nice-ish shader on it.

From there I can start learning how various graphics algorithms work. I’m not planning to make my own game engine, just understand how they work a bit better.

C++ is a royal pain innit

I’m developing on my Windows desktop machine with the fancy graphics card and all that.

First problem was to get a compiler. I don’t really like Visual Studio because it’s a huge ponderous program and I learned C++ on Linux, where you just invoke the compiler on the command line. It turns out there is a port of the Gnu C Compiler to Windows called MinGW... but I may not end up actually using that because of other tools I ended up using.

The first question I had was, am I supposed to implement my own linear algebra library? While this entire project is reinventing the wheel to some degree, linear algebra isn’t a particular wheel I care to reinvent. It turns out that once I figured out what to actually search for (even with a qualifier like ‘Euclidean’, ‘vector’ is not a good search term for C++, but ‘matrix’ is, and in fact what I should have been searching is ‘linear algebra’) it turns out there are actually loads of them.

So I hesitantly settled on GMTL.

The next problem I had was, how the heck do you manage packages and dependencies in C++? Other languages have a nice convenient package manager which lets you list the dependencies of your project in your source code repository, and when someone else downloads your git repo, they can just call some command to automatically download and install the packages you need.

C++, by virtue of being much older than the trend towards every language having its own package manager, is a much messier situation. On Linux, most distros provide various C++ libraries in their package manager, but there’s no such luck on Windows, and in any case either way there’s no easy way to specify dependencies.

So should I just dump all the code of the library in my project’s folder, which sounds pretty bloated? This seems to be what people actually do. Should I upload the library code to github along with my project? I really didn’t want to do that.

One possible solution is to use a git feature called submodules. That lets me mark part of my module as a ‘submodule’ based on another git repository, and if I push the module to github, the submodule contents wouldn’t be included but can be installed with a console command. That’s exactly what I want... if the library I want has a git repository associated with it. GMTL doesn’t.

There is a relatively recent attempt to make a C++ package manager/dependency system, called Conan. There’s also another, no-longer-maintained one called CPM. Conan is very flexible and proved easy to set up, albeit defaulting to the Visual Studio compiler through CMake. Well, as long as I can run it from the command line, I don’t really mind whether it’s VS or MinGW. But... GMTL wasn’t on their list.

On the other hand, GLM, another graphics-targeted library with linear algebra code was present. It has a lot of downloads. However, this one didn’t come highly recommended on the above Stack Overflow thread on linear algebra libraries. Someone called GameDeveloper said:

well, it provide graphics programming vector and matrices. it introduces nice amount of overhead to keep compliant on GLSL (if you can do it in GLSL, most times doing it in GLSL is better especially with GL 4.x), and miss many graphics programming primitives (frustum, AABB, BB, ellipsoid). Its swizzle interface it's obese. Much better alternative would be if it had ".xyzz()" functions generated with some code generation. It is perfect when you have to prototype opengl applications and starts showing its negative sides on bigger projects. never code a math library.

That said, since making a rasterisation program is essentially “prototyping an openGL application", maybe that isn’t so bad. And it will make it easier to learn GLSL later. (AABB is Axis-Aligned Bounding Box, BB is therefore most likely Bounding Box, frustums are of course important in the perspective transform; I’m not sure I’ll need ellipsoids).

Another option for a much more generic linear algebra library also available on Conan is Eigen. That may be overkill for what I want to do, thoguh, which is probably covered in GLM. I’m going to stick with GLM for now.

Next post, some info on rasterisation, and hopefully the details of an actual attempt to implement this thing with code.
