One summer day in 1933, in a brief pocket of time between the two World Wars, a British man named Maurice Wilson clutched the stick of his tiny, open air biplane and watched his fuel gauge dwindle. He had only learned to fly two months earlier, but inexperience was not his biggest problem. His lengthy list of troubles included the angry British officials he had just left behind in Bahrain, the certainty of arrest if he turned left to land i..

lstopo There are many ways to find out what’s the CPU you are using and more info about it. For Windows and Android, there is CPU-Z . For Mac, there is System Report or command line sysctl -a | grep machdep.cpu. On Linux, there are plenty. You can check with htop, sudo lshw -C cpu, lscpu or the good old less /proc/cpuinfo. Today, I’ve found out Portable Hardware Locality (hwloc) tool. What is hwloc ? According to the official site,

The role of the full-stack-data-scientist is not what it once was. With the advent of more powerful tooling, new industry standards in MLOps, and greater investment in platforms, the day-to-day of a data scientist has changed significantly at Stitch Fix. The difference, however, is subtle. The structure of their job remains the same – engineers still do not write ETLs and data scientists function as generalists , but they now hav....

Introduction In episode 2, Bill designed a database for his dependency manager to enable Go developers to have reproducible,durable and secure builds. This database will house the hash value for each of the dependencies stored. During runtime, these hash values are compared with the dependencies a user has locally. Bill’s tool makes this comparison to make sure the user has the right version of the dependency. Each team making use of Bill’..

|
Introduction In episode 3, Bill needed to figure out how to share ownership of his dependency manager’s database in a secure and efficient manner. Bill is the only stakeholder with full access to his dependency manager’s database. That is, he is the only person with the ability to mutate the database. This is problematic because he can freely edit the database which will make it harder for other users to confidently perform audits. And as ..

You can build your own voice assistant to avoid the questionable privacy consequences of bringing an Alexa or Google Assistant into your home. In this post I’ll explain how I did it using commodity hardware without any need for network communication outside of my own private LAN. Even more stunning, the voice recognition doesn’t suck and it may actually be useful to you . Figure 1: AIY Voice Kit Hardware. Yes, it’s cardboard!....

It’s mind-blowing that today scientists can “extract genetic material from the letters written [in 1475] by Vlad Dracula […] and, from that, build up a picture of not only the physical makeup of the Wallachian warlord who became known as Vlad the Impaler but also the environmental conditions in which he lived.” Also, I’m not surprised that similar investigations revealed that Mikhail Bulgakov was under morphine when he wrote his masterp..

This post analyses the resistance of the Hodges–Lehmann estimator to low-density regions of a distribution. In Pragmastat, this estimator is Center — the recommended robust location estimator. Confidence intervals are available via CenterBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat In the previous posts, I discussed the concept of a resistance function that shows the sensitivity of the given estimator to the l..

Introduction In episode 1, Bill finished by describing the dependency management conundrum Go faced in its early days. Prior to the Go team providing the module system, developers were on their own to find a solution. Engineers in the Go community did propose different solutions, but there was no general consensus on which tool to use for dependency management. In this video, Bill will begin to architect a solution to the reproducible bu..

Today I upgraded to JetBrains’ Rider 2022.3. Startup speed has been enhanced, and full .NET 7 and C# 11 support is included. So far, my favorite feature is the conversion of regular and verbatim strings into their raw counterparts (it’s often the small, simple things.) My second best is the fulls upport for WSL2 remote development. This one took a good while to come out of the trenches, but better late than never, I’d say.

Back in 2020, I wrote a semi-automatic yasnippet to generate Swift initializers . I say semi-automatic because it could have been a little smarter. While it helped generate some of the code, what I really wanted was full context-aware generation. The Swift struct already had a few properties defined, so a smarter yasnippet should have been able to use this info for code generation. With an extra push, we could have written a smarter....

Introduction In this video, Bill will introduce the concepts of what a blockchain is, the benefits of a blockchain, and the network environment it operates in. Bill describes a blockchain as a single, append-only, transparent, publicly available and cryptographically auditable database. Blockchains operate using a peer to peer (p2p) network with no single node designated as the central authority. To better understand what all that means,..

The fact that I have to have a full WebKit process and actual JS running just to view an EPUB is really infuriating. Can’t anything just be a ruddy DOCUMENT format anymore‽ To be fair: EPUB is actually a good use-case for semantic XHTML5, WAI-ARIA, DPUB-ARIA, MathML, and RDF serializations. This does call for some sort of web engine, but not necessarily a complete browser engine capable of running web apps. Most of the rest of the..

You said something I’d like to draw attention to: I have been banned from LinkedIn temporarily myself 4 times for “looking at too many profiles”. It is in their Terms and Conditions that they can ban you for that. LinkedIn is aggressively anti-scraping for all the wrong reasons. Bing (obviously), Google, Yandex, and some others get preferential treatment; Microsoft is incentivised to keep the number of non-Bing web indexes low. Co....

I find the 20’s to the 50’s a very fascinating time in American history. Perhaps because it is so very different from the life we have today, but still feels relatively closer. Maybe even more so because the 20’s and 30’s were so radically different from just 50 years prior. So in pursuit of learning more about the history of the cinema and to understand more about what life was like by watching what they watched, I’m going to watch the top..

This was originally a reply to another post. That post has been deleted. Can we agree to rewrite all the GNU utilities in Rust The advantage of POSIX coreutils is their portability and universality; I can expect them to be present on any POSIX system. If re-writing will sacrifice portability, we might as well do a clean break from POSIX and seek to improve upon existing coreutils rather than replace them. I listed some on my “us..
