You can read more from me at my site: http://www.joshualyman.com

A technologist, founder, and current Googler, I've repeatedly taken products from inception to commercial success across sectors, from startups to Fortune 10 companies. My specialty lies in bridging the gap between business vision and technical execution, deeply engaging with code and who mentors teams. Beyond engineering, I bring a global perspective from living abroad for nine years and speaking fluent French.

I love astronaut.io! Open it in an incognito window so that your YouTube watch history doesn't get too crazy.
ljoshua··on Mozilla introduces updates to tab management in Firefox
You can pre-select multiple tabs to add to the group when creating a new one. It will also automatically add newly opened tabs originating from a grouped tab in the same group. Not vertical like TST, but a very nice quality life improvement in the native browser.
ljoshua··on Finite State Machine Designer
Haha! For those unsure, this is one of the co-founders of Figma, and he also maintains esbuild. See the root domain (https://madebyevan.com/).
ljoshua··on Puget Systems' Perspective on Intel CPU Instability Issues
I second that. I've only had a chance to buy one PC from them (I usually run Macs), but the level of attention to detail and customer service from Puget was bar none the best I've had from any tech outfit.
ljoshua··on Study: For every 1k Google Searches, only 360 go to the open web
I feel like the headline is torturing the data a little bit. Of the three primary buckets (a click, search session ends, or another search), only the "search session ends" bucket feels like it can really be construed to be not going to the open web. This is presumably because the SERP presented the answer the user was looking for, possibly because of an AI Overview answer, seeing a location on the mini-map, etc.

A search that then results in another search (22%) could either be the user realizing their terms weren't getting them to the right direction so they modify the search, or just changing their mind. The article notes that more research is needed here. Doesn't seem like they are "not going to the open web."

That leaves the biggest bucket (42%) where 79% go to a website, 29% go to a Google property, and 1% go to a paid click destination. The 79% is of course considered the "open web" here, but presenting Google properties as not the open web seems funny. There's no walled garden, login, or payment required to access those destinations, and they're usually presented in search results because of their relevance to the search. Even the 1% paid clicks bucket, while they are ads, technically still go to the open web.

So in general I feel like this is trying to paint a negative picture that the data doesn't really support. If nothing else, the definition of "open web" here feels overly selective, to the detriment of the message. But this is the Internet, so I suppose I shouldn't be surprised that the headline is clickbaity. :)

ljoshua··on Show HN: Quickly scan HN for new articles
Same here. Saves me so much time and very reliable. There are also a few settings one can tweak (limit to homepage or top X%, for example) to make it even better.
ljoshua··on I didn't touch a thing – just some cables and a monitor – and my computer broke
Reminds me of the stories on The Daily WTF [0], one of the treasures of the internet.

ljoshua··on Joint FAO/WHO/WOAH preliminary assessment of recent influenza A(H5N1) viruses
Excerpt from conclusion:

> At the present time, based on available information, WHO assesses the overall public health risk posed by A(H5N1) to be low, and for those with exposure to infected birds or animals or contaminated environments, the risk of infection is considered low-to-moderate. This risk requires close monitoring and WHO and partners will continue to regularly assess and publish public health risk assessments for avian influenza.

ljoshua··on Ross Anderson
A very great tribute. I particularly liked this line:

> "He was the first person to understand that security problems are often actually economic problems."

I had a wise, old professor in college who taught us, almost as a side comment, that every technology and business problem was actually a people problem under the covers. If you could deal with the underlying human problem, you'd often take care of most, if not all, of the superficial tech/business problem. I think this and Ross's viewpoints are a very important principle.

ljoshua··on Google: Angular and Wiz Are Merging
No relation.
ljoshua··on Ikigai: What We Got Wrong and How to Find Meaning in Life
This was a nice reframing of the concept of ikigai as I've heard it, and a quick consult of Wikipedia for ikigai [0] shows that it's largely accurate.

I'd also throw out there that one can derive a lot of purpose and meaning in life from religion as well. I certainly do. There are many motivating factors in life, and some core religious beliefs can do this quite effectively, in a positive manner.

ljoshua··on I'm So Old: Web Edition
Thank you for your vulnerability and wise advice here. And I’d be willing to guess that your nephews have a ton of fun with you. :)
ljoshua··on What a major solar storm could do
See the Carington Event: https://en.m.wikipedia.org/wiki/Carrington_Event

It doesn’t discuss seeing it during the day, but it was visible in places where it would never otherwise be.

ljoshua··on Satya Nadella uses an IBM AS/400 in 1993
What I find most interesting from this clip is that, if you just swapped out some of the product names and acronyms, it would largely sound like a technical presentation that could be given today. “Here’s a database, we want to connect it with SQL to another product for visualizing the data, and we’re going to add some automation to take care of business process X.”

Surely things have gotten faster and (in some cases!) more efficient, but we are doing the same thing 30 years later that we were excited about in 1993. In a way that’s both comforting and darkly funny.

ljoshua··on Outlook is Microsoft's new data collection service
I’m curious to know where your productivity boosts came from, as those are always a good motivating factor for me to try something new.
ljoshua··on Was an ancient bacterium awakened by an industrial accident?
Also fascinating because we have video footage of it, and it’s as crazy as it sounds.

Quick 8-minute documentary on it that I found interesting: https://youtu.be/p_iZr2-Coqc?si=kthsdehqzJlvDfkg

ljoshua··on It takes 12 people to use the 18k Sphere camera
Some mind-blowing technical details about the camera and recording system itself are in a secondary article linked from this one as well:

https://petapixel.com/2023/06/12/sphere-studios-big-sky-cine...

Bits like a fiber-to-media recording system and custom GPU-based processing systems, really awesome project

ljoshua··on I Have Blocked OpenAI
I agree that LLMs are almost more likely than not to answer documentation questions wrong, to hallucinate methods that don’t exist, or just be silly. But the value I see in allowing LLMs to train on documentation is in the glue code that an LLM could (potentially!) generate.

Documentation, even good docs, usually only answer the question “What does this method/class/general idea do?” Really good docs will come with some examples of connecting A and B. But they will often not include examples of connecting A to E when you have to transform via P because of business requirements, and almost never tell you how to incorporate third-party libraries X, Y, and Z.

As an engineer, I can read the docs and figure out the bits, but having an LLM suggest some of the intermediary or glue steps, even if wrong sometimes, is a benefit I don’t get only from good documentation.

ljoshua··on Alternaive to Fastmail (using a custom email domain)
Have you reached out to FM support? I have one $50 account at my custom domain and neither of those problems are issues for me at all. It always defaults to my custom domain, and I log in with my custom domain as well. I have several other aliases and domains that I can use as well, but those are not the default (and I've never used the @fastmail domain).

Support has always been very responsive in my experience. I'd try them first.

ljoshua··on DARPA’s silent MHD magnetic drives for replacing naval propellers
You’ll just have to speed up the recording to 10x to find out… :)
ljoshua··on Disney and the Great Streaming Purge
I believe it's the residual licensing costs to the works that are the expense, not the physical storage of it.
ljoshua··on Juice’s RIME antenna successfully unjammed
Just wanted to say that this is the kind comment chain I come to HN for, when a Mars rover driver comes in with a relevant and amazing anecdote. Absolutely love this. Thank you foobarbecue!
ljoshua··on U.S. bank lending slumps by most on record in final weeks of March
When the article says, “Commercial bank lending dropped nearly $105 billion in the two weeks ended March 29, the most in Federal Reserve data back to 1973,” and later also notes that banks “divested” themselves of billions of dollars in loans, where is the money going?

Are they selling the loans off their books to third parties? Or are they just refusing to make new loans that they would have otherwise consistently made?

ljoshua··on Remastered 'Myst Mobile' Game Now Available on iPhone and iPad
Great recommendations. My wife and I played and solved Obduction together too, it was a ton of fun!
ljoshua··on Eastern US power grid orders cuts, issues system wide emergency
One must put in perspective the difference though. This is a single, contained event during a fairly extreme weather scenario. Contrast that to what could have been a whole winter-long event in Europe had the continent not taken extreme and well-coordinated action very early (and had the international community coordinating as well). Let’s compare them on proper footings.
ljoshua··on Eastern US power grid orders cuts, issues system wide emergency
This is the grid operating as intended. There are no mandatory or rolling blackouts yet. That is Stage 3; PJM is calling for Stage 2 countermeasures to avoid going to Stage 3. The operators feel comfortable that this will give them the margin required per the quote on the article, and affects businesses without need for constant power (and this is a known prior agreement for those businesses, with remuneration).

Electricity is a commodity to be managed like all others, and during times of extreme cold this is good management. I think it’s easy to bash grid operators (I know, I live in Texas!) but this seems like proper operating procedure here.

ljoshua··on The Golden Rule of Personal Finance
Lucky! I love YNAB, but I'm glad that 95% of my spending is on my non-Amex cards and accounts, because the Amex accounts only sync successfully once in a blue moon, even after repeated reauthorizations. Any tips?
ljoshua··on The Sounds of CDMX
This is a really fun, interactive experience. And the rest of the site is worth exploring too for its unique presentations.

Having lived in Mexico City myself and returning there a few times a year right now, this is definitely a pretty accurate representation of many of the sounds you'll see/hear (with the exception that the folks playing the sounds aren't always as smiley as the way the cutesy art makes them look). A fun way to learn about another culture though.

ljoshua··on Ask HN: How do you manage your household cashflow?
For real though.

It takes a couple of months to 1) get your head wrapped around the core concepts and 2) get budgets and its automatic matching working well, but after that it provides an amazingly good lens into your funds.

Accountability has gone up for me and my wife, and it’s helped us make decisions that, while sometimes hard, actually made an impact. Confidence in our true financial position has also increased.

ljoshua··on Ask HN: What are good genealogy/family history/immigration search engines?
On the FamilySearch wiki linked to in the parent, there are also many country-specific guides that link to resources both inside and outside of FamilySearch. Those that may be of interest to you given the countries you mentioned:

- Germany: https://www.familysearch.org/en/wiki/Germany_Genealogy

- Ukraine: https://www.familysearch.org/en/wiki/Ukraine_Genealogy

- Russia: https://www.familysearch.org/en/wiki/Russia_Genealogy

Also see the main wiki page, which has a Locality finder and may have other links depending on how far back you want to go (e.g., German Empire): https://www.familysearch.org/en/wiki/Main_Page

And of course, search the entire FamilySearch database too, which aggregates many, many sources: https://www.familysearch.org/search/
