2023-02-21 I made a game, Tippy Coco

Tippy Coco is a free, open-source game by Chris Coyne (chriscoyne.com / @malgorithms). The inspiration for this game was Slime Volleyball, a 1999 Java Applet by Daniel Wedge & Quin Pendragon. I called an earlier version of this game They Came from the Ground.

The game is programmed in JavaScript (well, TypeScript) and uses simple HTML Canvas drawing.

Music in Tippy Coco is by my friend Christian Rudder, of the band Bishop Allen. "Rejected!" and "Slam!" and "Kiss" were voiced by Jennie, Cameron, and Abbott Coyne. And the character TippyCoco is named after our friends' dog, TippiCocoa. image-20230224205220716

I just put it here, it is so cool

Snort is the foremost Open Source Intrusion Prevention System (IPS) in the world. Snort IPS uses a series of rules that help define malicious network activity and uses those rules to find packets that match against them and generates alerts for users.

Snort can be deployed inline to stop these packets, as well. Snort has three primary uses: As a packet sniffer like tcpdump, as a packet logger — which is useful for network traffic debugging, or it can be used as a full-blown network intrusion prevention system. Snort can be downloaded and configured for personal and business use alike.image-20230224205015067

How the build systems and dependency managers are now more standard. How Clang affected the standard toolset in all areas, forming not only a baseline for compilers, but also formatters, code analyzers, and IDEs. How many code analyzers exist for C++ and why there is still room for improvement. How unit testing and code coverage solutions can be used effectively.

2023-02-10 Is Seattle a 15-minute city? It depends on where you want to walk

What makes this article interesting, besides the main content, are references to apps, maps and APIs from where the data got fetched.

This could be a pivotal year for mobility in Seattle. In the final week of January, Seattle won $25.7 million in federal grants to build safer streets, made transit free for 10,000 Seattle Housing Authority residents, and solicited public feedback on a major update to the city’s Comprehensive Plan. To transform this momentum into meaningful change, we need a catalyst—a coherent, powerful vision for moving around Seattle.

Consider the 15-minute city: first imagined by Carlos Moreno and most fully realized (so far) in Paris, this model describes a metropolis where residents can satisfy the full spectrum of their daily needs within a 15-minute walk or bike ride.

​ 2023-01-17 The Cab Ride I'll Never Forget Kent Nerburn

There was a time in my life twenty years ago when I was driving a cab for a living. It was a cowboy’s life, a gambler’s life, a life for someone who wanted no boss, constant movement and the thrill of a dice roll every time a new passenger got into the cab.

What I didn’t count on when I took the job was that it was also a ministry. Because I drove the night shift, my cab became a rolling confessional. Passengers would climb in, sit behind me in total anonymity and tell me of their lives.

2023-02-11 How to Train Really Large Models on Many GPUs? Lil'Log

In recent years, we are seeing better results on many NLP benchmark tasks with larger pre-trained language models. How to train large and deep neural networks is challenging, as it demands a large amount of GPU memory and a long horizon of training time.

However an individual GPU worker has limited memory and the sizes of many large models have grown beyond a single GPU. There are several parallelism paradigms to enable model training across multiple GPUs, as well as a variety of model architecture and memory saving designs to help make it possible to train very large neural networks.

2023-01-25 Event Hubs ingestion performance and throughput Vincent-Philippe Lauzon’s

Here are some recommendations in the light of the performance and throughput results:

  • If we send many events: always reuse connections, i.e. do not create a connection only for one event. This is valid for both AMQP and HTTP. A simple Connection Pool pattern makes this easy.
  • If we send many events & throughput is a concern: use AMQP.
  • If we send few events and latency is a concern: use HTTP / REST.
  • If events naturally comes in batch of many events: use batch API.
  • If events do not naturally comes in batch of many events: simply stream events. Do not try to batch them unless network IO is constrained.
  • If a latency of 0.1 seconds is a concern: move the call to Event Hubs away from your critical performance path.

Let’s now look at the tests we did to come up with those recommendations.

2023-02-10 How to build an in-house on-call training program - Blog

A critical element of a successful SRE team is maintaining an on-call schedule. Engineers need to be at the ready on a predetermined rotation to fix issues on existing services and infrastructure as they arise.

Having an on-call schedule is only part of the equation. Your SRE and DevOps engineers need to be trained in how to actually resolve issues. A complete training program ensures that proper procedure becomes second nature for your team, so that they can arrive at resolutions as quickly as possible.

Let’s take a closer look at why these programs are necessary, what an effective in-house, on-call training program generally looks like, and how to leverage one to train and mentor new members of your SRE team.

labrador 12 hours ago | next [–]

I handle it by collecting quotes that tell me to knock it off. I've since started to focus on just the things I really care about:

  The purpose of knowledge is action, not knowledge.
  ― Aristotle

  Knowledge isn't free. You have to pay attention
  ― Richard Feynman

  "Information is not truth"
  ― Yuval Noah Harari

  If I were the plaything of every thought, I would be a fool, not a wise man.
  ― Rumi

  Dhamma is in your mind, not in the forest. You don't have to go and look anywhere else.
  ― Ajahn Chah

  Man has set for himself the goal of conquering the world,
  but in the process he loses his soul.
  ― Alexander Solzhenitsyn

  The wise man knows the Self,
  And he plays the game of life.
  But the fool lives in the world
  Like a beast of burden.
  ― Ashtavakra Gita (4―1)

  We must be true inside, true to ourselves,
  before we can know a truth that is outside us.
  ― Thomas Merton

  Saying yes frequently is an additive strategy. Saying no is a subtractive strategy. Keep saying no to a lot of things - the negative and unimportant ones - and once in awhile, you will be left with an idea which is so compelling that it would be a screaming no-brainer 'yes'.

2023-01-26 Resilience and Waste in Software Teams – Jessitron

Keeping libraries and components up-to-date, keeping code readable, updating our automations, improving our observability, bringing other developers up to speed– these are a few of the tasks developers need to do regularly. Any one of these tasks could have no noticeable impact in the future, and any one of them could prevent the next big security incident. The most likely outcome of each is a smoothing of future work, a decrease in unpleasant surprise.

Last time I implemented a feature in the Honeycomb UI, I needed some React functionality that was only in the latest version. I looked at our package.json, and lo! We were on the latest version! I rejoiced, and my work proceeded.

Many of these tasks don’t make it onto the roadmap, because when I look at the overhead of creating a ticket, discussing it in planning, advocating for it–then I can’t. It isn’t worth that. I can’t justify any particular one. Instead, these are best done as we go. Oh look, this test is in the old framework, let’s update it. This name confused me, let’s change it. In the kitchen, I always wash the knives and put them away immediately as soon as I’m done chopping.

2023-01-18 20 Things I've Learned in my 20 Years as a Software Engineer - Simple Thread

  1. I still don’t know very much
  2. The hardest part of software is building the right thing
  3. The best software engineers think like designers
  4. The best code is no code, or code you don’t have to maintain
  5. Software is a means to an end
  6. Sometimes you have to stop sharpening the saw, and just start cutting shit
  7. If you don’t have a good grasp of the universe of what’s possible, you can’t design a good system
  8. Every system eventually sucks, get over it
  9. Nobody asks “why” enough
  10. We should be far more focused on avoiding 0.1x programmers than finding 10x programmers
  11. One of the biggest differences between a senior engineer and a junior engineer is that they’ve formed opinions about the way things should be
  12. People don’t really want innovation
  13. Your data is the most important part of your system
  14. Look for technological sharks
  15. Don’t mistake humility for ignorance
  16. Software engineers should write regularly
  17. Keep your processes as lean as possible
  18. Software engineers, like all humans, need to feel ownership
  19. Interviews are almost worthless for telling how good of a team member someone will be
  20. Always strive to build a smaller system

If so, this article was written for you.

2022-12-14 How does GPT Obtain its Ability? Tracing Emergent Abilities of Language Models to their Sources

There are three important abilities that the initial GPT-3 exhibit:

  • Language generation: to follow a prompt and then generate a completion of the given prompt. Today, this might be the most ubiquitous way of human-LM interaction.
  • In-context learning: to follow a few examples of a given task and then generate the solution for a new test case. It is interesting to note that, although being a language model, the original GPT-3 paper barely talks about “language modeling” — the authors devoted their writing efforts to their visions of in-context learning, which is the real focus of GPT-3.
  • World knowledge: including factual knowledge and commonsense.

Where do these abilities come from?

Generally, the above three abilities should come from large-scale pretraining — to pretrain the 175B parameters model on 300B tokens (60% 2016 - 2019 C4 + 22% WebText2 + 16% Books + 3% Wikipedia). Where:

  • The language generation ability comes from the language modeling training objective.
  • The world knowledge comes from the 300B token training corpora (or where else it could be).
  • The 175B model size is for storing knowledge, which is further evidenced by Liang et al. (2022), who conclude that the performance on tasks requiring knowledge correlates with model size.
  • The source of the in-context learning ability, as well as its generalization behavior, is still elusive. Intuitively, this ability may come from the fact that data points of the same task are ordered sequentially in the same batch during pretraining. Yet there is little study on why language model pretraining induces in-context learning, and why in-context learning behaves so differently than fine-tuning.

Previously this happened pretty widely but generally under the table. (Is there any programmer who does not have a snippets folder or their own private library for scratching that one particular itch?) One of the great wrinkles that OSS throws into this is that OSS is public by default, and that's game changing.

    Baader-Meinhof Phenomenon:

    Ostrich Effect:

    We often try to avoid info that we fear will cause us stress. Thus bills and work emails remain unopened, bank balances remain unchecked. This is counterproductive because ignoring a problem doesn't eliminate the problem or your anxiety; it only prolongs them.

    Nobel Disease:

    We idolize those who excel in a particular field, inflating their egos and afflicting them with the hubris to opine on matters they know little about. By celebrating people for their intelligence, we make them stupid.

C​

Learning C was quite difficult for me. The basics of the language itself weren’t so bad, but “programming in C” requires a lot of other kinds of knowledge which aren’t as easy to pick up on:

  • C has no environment which smooths out platform or OS differences; you need to know about your platform too
  • there are many C compiler options and build tools, making even running a simple program involve lots of decisions
  • there are important concepts related to CPUs, OSes, compiled code in general
  • it’s used in such varied ways that there’s far less a centralised “community” or style than other languages

    No prototypes. Just make the game. Polish as you go. Don't depend on polish happening later. Always maintain constantly shippable code.

    It's incredibly important that your game can always be run by your team. Bulletproof your engine by providing defaults upon load failure.

    Keep your code absolutely simple. Keep looking at your functions and figure out how you can simplify further.

    Great tools help make great games. Spend as much time on tools as possible.

    We are our own best testing team and should never allow anyone else to experience bugs or see the game crash. Don't waste others' time. Test thoroughly before checking in your code.

    As soon as you see a bug, you fix it. Do not continue on. If you don't fix your bugs your new code will be built on a buggy codebase and ensure an unstable foundation.

    Write your code for this game only - not for a future game. You're going to be writing new code later because you'll be smarter.

    Encapsulate functionality to ensure design consistency. This minimizes mistakes and saves design time.

    Try to code transparently. Tell your lead and peers exactly how you are going to solve your current task and get feedback and advice. Do not treat game programming like each coder is a black box. The project could go off the rails and cause delays.

    Programming is a creative art form based in logic. Every programmer is different and will code differently. It's the output that matters.

To understand how and why this should be, we first outline the evolutionary background in primate sociality from which our human social world has emerged. We then review defining features of that human sociality, putting forward a framework within which one can understand the consequences of mass social isolation during the COVID-19 pandemic, including mental health deterioration, stress, sleep disturbance and substance misuse. We outline recent research on the neural basis of prolonged social isolation, highlighting especially higher-order neural circuits such as the default mode network. Our survey of studies covers the negative effects of prolonged social deprivation and the multifaceted drivers of day-to-day pandemic experiences.

    Social media sites are riddled with ads, trackers, and dark patterns. As much as I'd love to avoid using them for privacy reasons or time concerns, it's just not possible to keep up to date with current events without them.RSS ("Really Simple Syndication") gives you the best of both worlds. For the uninitiated, it is a way to "subscribe" to websites without having to browse them individually or signing up for newsletters. With a collection of RSS feeds, you can keep up with the latest updates from multiple sources (that offer an RSS feed) from within your feed reader.

    Error messages are part of our daily lives online. Every time a server is down or we don’t have internet, or we forget to add some info in a form, we get an error message. “Something went wrong” is the classic. But what went wrong? What happened? And, most importantly, how can I fix it?

  • 2022-10-16 If you want to terminate on an unexpected exception, then don't sniff at every exception; just let the process terminate - The Old New Thing

    The idea is that the Do­Something function uses an error code to report problems, but it is built with the help of functions that use exceptions to report problems. The Do­Something function sets up a try/catch that catches any exceptions that may emerge from the helper functions and uses a helper function to convert the exception to an HRESULT. If the exception cannot be converted to an HRESULT, then we terminate the process, because the helper functions threw a disallowed exception.

  • 2022-10-26 systemd Shutdown Units - Poseidon Labs

    Designing a system to shutdown gracefully can be tricky. In an ideal world, every service would be managed by a systemd unit. ExecStart would start a process that handles SIGTERM by stopping itself and an ExecStop would inform the process and block to gracefully stop the process and its resources.

    But not all software stops gracefully or does a full teardown of what it set up. In this post, we’ll look at systemd’s shutdown behavior and strategies for writing systemd units that perform custom cleanup tasks before shutdown.
