This sort of behavior puts a huge burden on the listener because it makes them responsible for your emotional state. Their options are to deny you the emotional state you want, or to give it to you by lying. This is exhausting and will cause people to limit the amount of social time they spend with you.

The {vetiver} package provides a set of tools for building, deploying, and managing machine learning models in production. It allows users to easily create, version, and deploy machine learning models to various hosting platforms, such as Posit Connect or a cloud hosting service like Azure.

I hope to show how to demonstrate how easy model deployment can be using Posit’s open source tools for MLOps. This includes {pins}, {vetiver}, and the {tidymodels} bundle of packages along with the {tidyverse}.

Although the architect could code, as the title suggests, there are other ways for the architect to stay engaged with the delivery, such as pairing and peer reviews.

Rotating the architect role among different team members carries the benefit of increasing the overall team’s working architectural knowledge. Team members gain a better understanding of all the roles involved in delivery, leading to empathy between team roles, improved intra-team interaction, and a better overall product by diversifying the viewpoints applied to each role.

Similarly, when I ask other architects how much they’ve coded recently, more often than not I hear: “It’s been a while.”

Use ssh -f -N -L to run the port-forwarding session in the background.

I always allocate a year: six months to get up to speed on the internal culture, tools, and processes; another six months to get your first performance review as a “ramped-up” engineer.

I posted my interview tracker spreadsheet on Twitter under the guise of “being transparent.” The very next day, I was on a phone screen with a recruiter when they said “Yeah, I looked at the interview spreadsheet you posted on Twitter and just based on that I can tell you’re not going to be a good fit here. I just took this call as a favor to <redacted> since they referred you.”

Just because you’re getting a lot of offers to interview does not mean that you are a hot commodity. Nor does it indicate a high likelihood of obtaining an offer.

If you had asked me right after I got laid off how long it would take me to get back to work, I would have said three months – including two months of vacation. It took me a year.

I highly recommend Advent of Code to anyone looking to sharpen (or re-sharpen) their programming skills.

I used vim and make for my universal IDE.

For the most part, homebrew solved the installation problem. Almost every language had a homebrew-based option.

I stayed up each night until the problem was released (11pm my time), but I didn’t try to code up the solution right away. Instead, I read the problem description before bed and then thought about how to solve it while falling asleep. I usually woke up every morning with a full sketch of the solution in my head, or something close to it.

Here's my opinion, having written many thousands of lines of mypy code.

Typescript added rich type annotations to Javascript, which opened the door to refactoring and static analysis tools that facilitate development and maintenance of large Javascript projects.

Overall, the code was significantly shorter compared to the tkinter version I did last year. That version had a few more features, but I'd say Textual felt much easier to reason about.

In Python, everything is an object – integers, strings, lists, functions, even classes themselves.

The larger the capacity of an SSD, the more data can be written to it during its working life.

If you know the TBW for an SSD and the total amount of data that has been written to it during its lifetime, it’s simple to estimate the percentage of its lifetime (as TBW) that has been used up, hence the amount remaining.

“If something is not definitely ‘yes’, it is definitely ‘no’”. This is the leading idea of Greg McKeown’s great book Essentialism: The Disciplined Pursuit of Less

Monastic and bimodal modes are rather reserved for professions that can manage work without intensive communication with people, like writers, scientists, researchers, etc. Journalist mode fits best to people that are experienced with deep work and can easily switch into that state. From my experience, the best option to start with deep work is the rhythmic mode.

As far as deep work is concerned, it can be performed in four different modes:

Of course, CSV is less flexible than JSON. It's suitable when you have a list of items with mostly the same properties, and no nested structures.

At 100,000 entries, this list would be 2.4 MB (that's ~63% less than the JSON)

CSV is a format that's more lightweight than JSON and super well suited to streaming.

Those methods will wait until the entire response has been downloaded, and then parse it. That's because JSON is not a streaming format

JSON is ubiquitous, more lightweight than XML but still flexible enough to represent any data structure you typically need

GitHub Copilot is incredible, and if you check what’s happening in the preview released as the Copilot Labs extension it will only get more amazing.

At the end of the day, Copilot is supposed to be a tool to help developers write code faster, while ChatGPT is a general purpose chatbot, yet it still can streamline the development process, but GitHub Copilot wins hands down when the task is coding focused!

Summary: In people with normal vision (or corrected-to-normal vision), visual performance tends to be better with light mode, whereas some people with cataract and related disorders may perform better with dark mode. On the flip side, long-term reading in light mode may be associated with myopia.

If headaches and eye strain persist, go see an optician. I had the same problem about a year ago; it turns out I am long-sighted and require glasses. Since then, my headaches and eye strain have pretty much stopped.

Many people perceive light mode as the cause of eye strain. But blue light, among other things, is actually the cause of it most of the time.

According to an analysis from the Wall Street Journal, the top 1% of Twitch streamers made over 50% of all money paid out by the platform in 2021. Furthermore, just 5% of users had made over $1,000 in the same year. Only 0.06% had made over the U.S. median household income of $67,521. In a survey of 5,000 community members composed of smaller Twitch streamers, Stream Scheme found that 76% were not able to reach Twitch’s $100 minimum payout threshold. Most others were making between $25-130 per month on the platform. 

In a 2021 leak of Twitch’s user data that included creator payouts, it was revealed that from August 2019 to October 2021, the top 100 streamers on the platform made anywhere between $9,626,712.16 and $886,999.17.

Cybersecurity researcher Curry told Forbes that, after seeing what could be done with just a VIN, it was “terrifying” that those identifying numbers were public.

For anyone with a Honda or Nissan car, it was possible for a hacker with a laptop to unlock or start their vehicles, locate them and raid personal data stored inside, cybersecurity researchers warned on Wednesday.

Ultimately the data scientists need me more than I need them; I’m the reason their stuff is in production and runs smoothly.

The main reason I soured on data science is that the work felt like it didn’t matter, in multiple senses of the words “didn’t matter”:

You can't think well without writing well, and you can't write well without reading well. And I mean that last "well" in both senses. You have to be good at reading, and read good things.

Talking about your ideas with other people is a good way to develop them. But even after doing this, you'll find you still discover new things when you sit down to write.

if you need to solve a complicated, ill-defined problem, it will almost always help to write about it. Which in turn means that someone who's not good at writing will almost always be at a disadvantage in solving such problems.

Try this code at app startup:

The trigger is when you allocate 700 or more container objects (classes, dicts, tuples, lists, etc) more than have been cleaned up, a GC cycle runs.

An absolute location can be confidently calculated only when four (or more) distance values are available.

First of all, in Python there are no such things as "files" and I noticed this is the main source of confusion for beginners.If you're inside a directory that contains any __init__.py it's a directory composed of modules, not files.

There are plenty of articles about the emergence of PyScript for embedding Python code directly into HTML, but until now the creation of browser extensions in Python has been something of a closed door.

In summary, terminal input is weird.  It’s weird largely because there’s a character-only pipe sitting between the terminal and shell.  And going one step back, the weirdness comes from the whole historical division of terminal vs. shell, which is based on emulating a physical hardware setup that hasn’t been built since the 80s. 

in MLflow 2.0, the mlflow.evaluate() API for model evaluation is now stable and production-ready. With just a single line of code, mlflow.evaluate() creates a comprehensive performance report for any ML model.

MLflow 2.0 also adds AutoML to MLflow Recipes, dramatically reducing the amount of time required to produce a high-quality model.

In MLflow 2.0, MLflow Recipes is now a core platform component with several new features, including support for classification models, improved data profiling and hyperparameter tuning capabilities.

As I think today microservice can do much more than just gives predictions using a single model, like:

notice that defaultdict not only returns the default value, but also assigns it to the key that wasn't there before:

dunder methods are methods that allow instances of a class to interact with the built-in functions and operators

take a step back and ask a basic question: “What kind of business value are we trying to provide?"

As of today, a lot of the things in ML are not automated. They are manual or semi-manual.

If we say that MLOps is just DevOps + “some things”, then CI/CD is a core principle of that.

Not everything can be tested/evaluated with a metric like AUC or R2. Sometimes, people just have to check if things improved and not just metrics got better.

I believe that packaging/building/deploying the vanilla, run-of-the-mill ML model will become common knowledge for backend devs.

MLOps engineer today is either an ML engineer (building ML-specific software) or a DevOps engineer. Nothing special here.Should we call a DevOps engineer who primarily operates ML-fueled software delivery an MLOps engineer?I mean, if you really want, we can, but I don’t think we need a new role here. It is just a DevOps eng.

The MLOps team should consist of a DevOps engineer, a backend software engineer, a data scientist, + regular software folks.

By becoming a hybrid you can choose how you want to be unique. Countless unique combinations are available to you.

Being U-shaped requires bravery, because it’s so unusual. U-shaped people tend to be subjected to greater skepticism, because no one else really understands what they alone can see.

T-shaped. They tend to be natural leaders because they understand how different responsibilities overlap, and how to construct effective teams and processes.

The U-shaped path means developing skills that are not often found together. Like engineering and dancing, or singing and design.

The T-shaped hybrid path is one that many curious people follow. You grow your skillset and experience in areas that are adjacent to your dominant expertise. For example engineering and design, or singing and dancing.

I’m excited to see community efforts like Obsidian Ava

The sentence in italics above was not written by me. It was autocompleted as I wrote in Obsidian, using the Text Generator plugin.

In some ways it is surprising that filtering text is so technically challenging. Text seems like it would be easier to manipulate than images.

After decades of experience, he knew and understood that the most meaningful conceptual progress he made on problems was always away from his computer: on a run, in the shower, laying in bed at night. That’s where the insight came. And yet, even after all these years, he still felt a strange obligation to be at his computer because that’s too often our the mental image of “working”.

Work at MIT found that brainstorming—where a bunch of people put their heads together to try to come up with innovative solutions—generally “reduced creativity due to the tendency to incrementally modify known successful designs rather than explore radically different and potentially superior ones.”

It's like paying a quarter of your house's value for earthquake insurance when you don't live anywhere near a fault line.

The second is when your load is highly irregular. When you have wild swings or towering peaks in usage.

The cloud excels at two ends of the spectrum, where only one end was ever relevant for us. The first end is when your application is so simple and low traffic that you really do save on complexity by starting with fully managed services.

The first interaction with a programming language should be what it can do for you, rather than an exhaustive glossary of what it is.

Python is known for using more memory than more optimized languages and, in this case, it uses 7 times more than PostgresML.

PostgresML outperforms traditional Python microservices by a factor of 8 in local tests and by a factor of 40 on AWS EC2.

For that, you must create a culture of fear in which it’s more important to show others you’ve been productive than to help the team achieve its goals.

Once you have convinced your team to estimate tasks, you can pressure people to work longer hours to prove they’re not bad at estimations.

But for all of its features, GitHub implements only a subset of git. For instance, GitHub lacks the default merge strategy of git—the fast-forward merge.

Be aware that staying at a company too long means you are likely to earn less over your career. But moving too soon means you won’t get the necessary experience that may benefit you later on.

Learning and adaptation – 3 – 6 months – getting to grips with the new company, team, and their processes. Creating value for the organization – 6 – 12 months – adding value to the business by becoming a functioning member of the team.Becoming a role expert – 6 – 18 months – owning the role completely and helping to shape the direction of the team.

Software engineers typically stay at one job for an average of two years before moving somewhere different. They spend less than half the amount of time at one company compared to the national average tenure of 4.2 years.

The average performance pay rise for most employees is 3% a year. That is minuscule compared to the 14.8% pay raise the average person gets when they switch jobs.

On “good” days, developers spend more time developing and less time collaborating

Speaking from my (R-biased) viewpoint, conda has posed some problems as well:

You can unknowingly be sending your critical database traffic in the clear because your client uses a default of allow or disable while the server you’re connecting to does, in fact, support SSL.

You can unknowingly be sending your critical database traffic in the clear because your client uses a default of prefer, allow or disable and the server you’re connecting to does not support SSL.

What Should I Do?

Many popular SQL clients do not use SSL by default. If you aren’t deliberate about choosing encryption, the connection will be unencrypted.

SSL is disabled by default in jdbc, npgsql, node-postgres, and pgx.

There are a lot of PostgreSQL servers connected to the Internet: we searched shodan.io and obtained a sample of more than 820,000 PostgreSQL servers connected to the Internet between September 1 and September 29. Only 36% of the servers examined had SSL certificates. More than 523,000 PostgreSQL servers listening on the Internet did not use SSL (64%)

At most 15% of the approximately 820,000 PostgreSQL servers listening on the Internet require encryption. In fact, only 36% even support encryption. This puts PostgreSQL servers well behind the rest of the Internet in terms of security. In comparison, according to Google, over 96% of page loads in Chrome on a Mac are encrypted. The top 100 websites support encryption, and 97 of those default to encryption.

new technologies leveraging techniques like spaced repetition mean it's much easier to remember what you learn

In 2019 the UK school inspection body Ofsted went further than this and changed their definition of ”learning” itself to “an alteration in long-term memory”.

to get faster at learning you must get more efficient at moving things into your long-term memory, i.e. stop forgetting things you learn. The less you forget the more you'll understand and the faster you'll learn.

To learn more than 4 new concepts we must move some of them into our long-term memory before learning the rest.

You can only understand something new if understanding it requires combining less than 4 new pieces of information.

our working memory has a maximum capacity of roughly 4. When reading about quantum mechanics we encounter new Concept 1 and store it in our working memory. Then when learning about Concept 1 we encounter Concepts 2, 3, and 4 and our working memory becomes full. We then cannot understand Concept 5.

transferring data across Availability zones within the same region is also a good way to save money

When you use a private IP address, you are charged less when compared to a public IP address or Elastic IP address.

But when you transfer data from one Amazon region to another, AWS charges you for that. It depends on the AWS region you are and this is the real deciding factor. For example, if you are in the US West(Oregon) region, you have to shell out $0.080/GB whereas in Asia Pacific (Seoul) region it bumps up to $0.135/GB.

When you transfer data between Amazon EC2, Amazon Redshift, Amazon RDS, Amazon Network Interfaces, and Amazon Elasticache, you have to pay zero charges if they are within the same Availability Zone.

When you transfer data from the internet to AWS, it is free of charge. AWS services like EC2 instances, S3 storage, or RDS instances, when you transfer data from the Internet into these you don’t have to pay any charge for it. However, if you transfer data using Elastic IPv4 address or peered VPC using an IPv6 address you will be charged $0.01/gb whenever you transfer data into an EC2 instance. The real catch is when you transfer data out of any of the AWS services. This is where AWS charges you money depending on the area you have chosen and the amount of data you are transferring. Some regions have higher charges than others.

Building machines and running downscaled tests is my late-night hobby.

We use Javascript everywhere, since we solve the “issues” caused by Javascript rendering we want to build as much expertise as possible in this field. But for the other parts, we are taking advantage of CloudFlare’s distributed system for fast response and global scalability. While our uptime guarantees are supported by Digital Ocean’s cloud platform. We also use a myriad of other SaaS providers to maximize our effectiveness.

we made sure to implement fail safes at each stage of the migration to make sure we could fall back if something were to go wrong. It’s also why we tested on a small scale before proceeding with the rest of the migration.

We mirrored PostgreSQL shards storing cached_urls tables in CassandraWe switched service.prerender.io to Cloudflare load balancer to allow dynamic traffic distributionWe set up new EU private-recache serversWe keep performing stress tests to solve any performance issues

“The true hidden price for AWS is coming from the traffic cost, they sell a reasonably priced storage, and it’s even free to upload it. But when you get it out, you pay an enormous cost.

In the last four weeks, we moved most of the cache workload from AWS S3 to our own Cassandra cluster.

After testing whether Prerender pages could be cached in both S3 and minio, we slowly diverted traffic away from AWS S3 and towards minio.

Phase 1 mostly involved setting up the bare metal servers and testing the migration on a small and more manageable setting before scaling. This phase required minimal software adaptation, which we decided to run on KVM virtualization on Linux.

The solution? Migrate the cached pages and traffic onto Prerender’s own internal servers and cut our reliance on AWS as quickly as possible.

After almost 10 years of remote work, it would be close to impossible for me to go back to an office.

On the internet today, it seems like it’s more common to use “absolute” domain names (like example.com).

The technical term for “THIS IS THE WHOLE THING” is “fully qualified domain name” or “FQDN”. So google.com. is a fully qualified domain name, and google.com isn’t.

So because domain names can actually be translated to something else in some cases, people like to put a "." at the end to communicate “THIS IS THE DOMAIN NAME, NOTHING GETS ADDED AT THE END, THIS IS THE WHOLE THING”.

zone files require a trailing dot at the end of a domain name (because otherwise they’re interpreted as being relative to the zone).

a fully qualified domain name is a domain with a “.” at the end!

If you work at a software company, there are some pretty common categories of work that people often avoid, including

Whenever people ask me for advice on career growth, I share what has worked reasonably well for me: find a growth company, one that really needs you to get work done, and then tackle the unpleasant work that everyone avoids.

That’s why it was such a life-changing event for me when I found Dash in 2012.

This is not "noise"

Imagine for a moment that, by some quirk of the universe, you are sharing your workspace with a time traveller. Specifically, yourself from 1 year in the future. How will you react to your new co-worker?

Mamba installs these packages in only a third of the time that Conda does. Much of that is due to less CPU usage, but even network downloads seem to be little faster; Mamba uses parallel downloads to speed them up.

So which should you use, pip or Conda? For general Python computing, pip and PyPI are usually fine, and the surrounding tooling tends to be better. For data science or scientific computing, however, Conda’s ability to package third-party libraries, and the centralized infrastructure provided by Conda-Forge, means setup of complex packages will often be easier.

My first recommendation would be fiction. Reading fiction is important to understand the cross-sectional variation in humanity, to understand how difficult generalisations can be, to just get a sense of how different social pieces fit together, and to get a sense of different historical eras – and plus, reading fiction is often just plain flat-out fun.

The different barcode types can be categorized as one-dimensional (1D) and two-dimensional (2D). While one-dimensional barcodes consist only of lines and are usually scanned horizontally with laser scanners, two-dimensional codes make use of vertical space as well and can only be scanned with devices that contain a camera, such as imager scanners or smartphones.

# "func" called 3 times result = [func(x), func(x)**2, func(x)**3] # Reuse result of "func" without splitting the code into multiple lines result = [y := func(x), y**2, y**3]

First of all, the map does a much better job at preserving the relative size and area of land and water masses, while reducing shape distortion. It is also designed to avoid dead ends, allowing the spherical nature of the world to be visualised by simply expanding the map in any direction.

Most web servers TCP slow start algorithm starts by sending 10 TCP packets. The maximum size of a TCP packet is 1500 bytes.

Second-order thinking is more deliberate. It is thinking in terms of interactions and time, understanding that despite our intentions our interventions often cause harm. Second order thinkers ask themselves the question “And then what?” This means thinking about the consequences of repeatedly eating a chocolate bar when you are hungry and using that to inform your decision. If you do this you’re more likely to eat something healthy.
