laserson··on The Legend of von Neumann [pdf]
I read this last year and also recommend!
laserson··on AI for Bio has a Fuzzy API problem
Nice essay Ankit!

I think there are two more factors worth touching on that make things difficult in drug discovery:

1. It feels like you're differentiating a bit but I always hear of the APIs being leaky. The selection of a target in the target discovery phase may drive which modalities are even available to try to engineer an intervention (e.g., intracellular vs extracellular targets can be addressed with different types of drugs). Clinical factors can also determine whether a particular modality is appropriate (e.g., keeping drugs refrigerated).

2. Costs create constraints that need to be applied at all the stages of the pipeline. Does gathering evidence during target discovery require a unique assay or access to very rare patient samples? What is the size of the addressable market? If you can only target a narrow patient population, it may not end up justifying the costs involved in running the clinical trials. If your chosen drug modality costs $500k to synthesize one dose, how will it be paid for?

laserson··on Nine things I learned in ninety years
There’s a well-known Louis Pasteur quote that I always liked:

“Chance favors the prepared mind”

laserson··on Ask HN: Spending Tracking Tools
I'm a big fan of Tiller [1], which is a paid service that basically just connects Yodlee to Google Docs or Excel. It will dump all your transactions and balance info into a spreadsheet and you can do what you want with it. It also has lots of templates for things like budgeting etc. I run a daily cron job that loads the transaction data and produces a nice Jupyter-based report. It will require some custom building, but the API plumbing is done for you.

laserson··on Kagi and Wolfram
One thing I miss from Google is relatively seamless integration with maps. Sometimes the address queries just fail for me on Kagi. And even when they don’t, Google’s maps are still far more useful IMO.
laserson··on Milk bag
In Israel they produce single-serving chocolate milk bags, which now mainly serve as a fond dose of nostalgia for me.
laserson··on Google Maps has become an eyesore
I’ve found Citymapper to give far more realistic routes and commute times on the NYC subway.
laserson··on Apple Music Classical
How does this compare with Concertmaster? It's basically a skin on top of Spotify for browsing classical music. It's free and pretty good. (There's also an app.) And I believe there is a version for Apple Music already?

laserson··on Ask HN: Who is hiring? (August 2022)
Patch Bio | Computational Biologist | New York City | Full-time | REMOTE

Patch Bio engineers DNA for gene therapy. We build technology to make gene therapies safer and more effective, and able to address a broader range of diseases. To do that, we work at the interface of genomics, machine learning, and DNA synthesis. We are a seed-stage, venture-backed biotech startup based in New York City.

We're looking for a Computational Biologist who will be the connective tissue between the wet and dry lab. You will design DNA libraries, analyze sequencing data, and build predictive models of genetic regulation.

laserson··on Apple acquires classical music streaming service Primephonic
Hadn't heard of Primephonic, but I have been using Concertmaster.app as a classical music-focused "skin" for Spotify and it's pretty good (and free!).
laserson··on Show HN: Places to watch ducks if you're sick of everything
I would love to see how this was implemented. Is this on GitHub or equivalent somewhere?
laserson··on Robert Caro and Kurt Vonnegut interview each other (1999)
It wasn't too fancy. I bought self-adhesive laminating sheets and reinforced with "book tape".

https://photos.app.goo.gl/QRCgTCUas1uYnY6x5

It did feel a bit sacrilegious slicing through the binding, but overall it worked out great!

laserson··on Robert Caro and Kurt Vonnegut interview each other (1999)
I used an X-Acto knife to slice it into 3 volumes and rebound them.
laserson··on Lets-plot: An interactive Python plotting library using ggplot's API
Altair does Grammar of Graphics and interactivity, and has ~6k stars.
laserson··on Fast high-level programming languages
I always thought Go might be a good candidate for some of these tasks.

laserson··on What happened to Mint?
I like TillerHQ (https://tillerhq.com/) for just extracting the financial data and dumping into a spreadsheet.
laserson··on Kary Mullis, inventor of PCR, has died
Also, the PCR reaction was effectively described in an earlier 1971 paper from Gobind Khorana (see final paragraph): https://www.sciencedirect.com/science/article/pii/0022283671...

laserson··on Self Studying the MIT Applied Math Curriculum
Strang just published a new book called "Linear Algebra and Learning From Data" [1] which I only just started but find to be quite enjoyable so far. It's simultaneously conversational but also quite terse (similar to "All of Statistics"). There are many advanced and very contemporary applications covered in the book, with a focus towards machine learning.

laserson··on Self Studying the MIT Applied Math Curriculum
Strongly agree. This was actually the text book when I took numerical methods at MIT. As far as math texts go, it is definitely a joy to read.
laserson··on Ask HN: What made you change your mind about a programming language/paradigm?
Hadley Wickham
laserson··on Airtable raises $100M at a $1.1B valuation
So many people use Excel/Google Sheets as a database rather than a spreadsheet, except you don't get any of the advantages of a database. It's astounding to me that there hasn't really been a webapp that's essentially just a nice collaborative frontend for a SQL database, which is how I use Airtable in my lab. I'm very happy to see they're on a sustainable path, and I hope they continue to support the use case of just-a-database. Congrats!
laserson··on Opentrons raises $10M for scientists to automate lab experiments with robotics
Congrats! We've had a good amount of fun playing with the OT-One (and also some frustrations). I think the large range of volumes is great, along with what seems to be more streamlined/accurate pipetting. I think the enclosure is also a solid feature.

One of my favorite features is the ability to use a simple Python API to define a protocol. Will this still be the case or do people have to use the GUI?

Is there a reasonable (cheap) path to upgrade?

laserson··on JupyterLab is ready for users
Is it possible to have a notebook and a console using a single, shared kernel?
laserson··on Why I left Academia: Part I
>I also thought it was funny that she complained about the committee not raising those questions when she submitted her proposal years ago.

At least in the sciences, your thesis committee is supposed to continually/regularly keep tabs on your progress, and help ensure you're making progress towards a passing dissertation. This is the committee's responsibility.

>An approved proposal does not in any way imply a seal of approval for every detail of the dissertation... come on now.

For sure, but the committee should know how things are progressing. In the sciences, the thesis defense is not really a "defense". It only gets scheduled when everyone basically agrees you will pass, and it's more of a celebration. It's very rare to have hostile defenses, and extremely rare for someone to fail. (If that happens, it's usually due to politics.)

>As if that is a valid response to this sort of response?

True, but it is concerning if they're bringing up possible plagiarism by her and Dr. Mao, while not following through on any kind of punishment/censure of the two of them.

laserson··on Apache Kudu – Fast Analytics on Fast Data
The Hail project at the Broad Institute makes use of Kudu I believe.

https://hail.is

Not sure if that group is paying for CDH, but this tool is definitely being built for others to use.

laserson··on Ibis: Scaling the Python Data Experience
And separate from the issue of whether it's a good or bad idea, it will shortly be possible to send raw SQL queries to the backend.
