jchallis··on Closing the world's schools caused children great harm
Hi Throwaway - sounds like Bright Horizons at Genentech? My 3 year old was at Bright Horizons at UCSF and they were even faster (~5 days) to figure out protocols to keep kids in the program so their essential worker parents could fight this war. Hard decisions were made and tradeoffs happened.
jchallis··on Appalachia is Dying. Pikeville is Not. (2016)
Whenever I visit Appalachia, I ask how would I view this city if I were in China.The comparison is apt because the light industry mountain towns feel a lot like their equivalents in the PRC.

As a county level city , Chinese Pikeville would be quite prosperous : education and healthcare steer it away from heavily polluting industries, it’s location on the river and highways make trade much easier than other parts of Eastern KY and its age demographics / poverty load / opiate abuse are comparatively good to the region. http://censusreporter.org/profiles/16000US2160852-pikeville-...

The trouble comes when you compare it to other cities in Kentucky : particularly Ashland or Richmond. Pikeville’s location is a serious liability and it’s flat population growth over the last decade suggest even if it’s not dying it’s not growing.

Stable regional centers are nothing to balk at - but the future does not look like Pikeville.

jchallis··on Spencer Silver, inventor behind the Post-it Note, has died
Just a personal thank you to Dr. Silver.

My paternal grandmother's family was rooted near Cynthiana, KY and the 3M Post-It-Note factory brought a lot of prosperity and middle class jobs to this very rural outpost. My Uncle would always keep a pack of Yellow Post-Its to show "Made in Cynthiana" on the back, a sign that the little town he spent his life in brought something useful and ubiquitous to the world.

jchallis··on Ask HN: How many projects do you work on at a time?
I've definitely transitioned from being the talent to being the agent. At work, I usually have 3-4 projects that are in my important/urgent quadrant and I spend most of my time making sure other people execute those effectively (on time, on budget , meet spec).

At home with my kids I usually have 4 projects in important / urgent (2 / kid). I'm way more involved in the day to day on these.

Could I do more ? Maybe - especially if I could do something particularly leveraged.

jchallis··on My experience with sexual harassment in the Scala community
There are known outliers : famously the Rolling Stone UVA rape case. https://www.theguardian.com/society/2019/dec/29/rolling-ston...

I do not think that's applicable here. I think this woman was coerced into nonconsensual sex.

jchallis··on Twitter is blocking tweets that criticize the Indian government
Unlike AR-15's that kill a great deal more children.
jchallis··on Soviet children’s books became collectors’ items in India
For our engagement , my new fiancée gave me a complete set of the Landau-Lifschitz course and I gave her a diamond ring. Both gifts were clear, glittering , timeless.
jchallis··on Problems with Eric Weinstein's “Geometric Unity”
That’s a pretty bold claim. The 1953 Nature paper laid out both the double helix and the Central Dogma (which is arguably the more important result). https://en.wikipedia.org/wiki/Molecular_Structure_of_Nucleic...
jchallis··on Dallas Mavericks No Longer Playing National Anthem Before Home Games
My employer also does not play the national anthem before I begin work. This is how I like it.
jchallis··on Salt Fat Acid Defeat: The restaurant before and after Covid
By and large restaurants are terrible at providing healthy, nutritious, sustaining food. If the pandemic helps promote more cooking at home and more nutritious eating, the failure of restaurants may have a silver lining.
jchallis··on My child has two parents. Why does day care call only me? (2018)
This was one clear way Carvana was a better buying experience than the lots - they never made my wife feel less than.
jchallis··on Claude Shannon Demonstrates Machine Learning (1952)
Electromechanical relays below the maze. Phone switches at the phone company labs.
jchallis··on Claude Shannon Demonstrates Machine Learning (1952)
By any reasonable definition of learning, the mouse adapts to a new situation.
jchallis··on 84% of Waterloo Software Engineering undergrads move to the US upon graduation
We welcome our Canadian brothers and sisters with open arms. My cofounder came from Waterloo and together we built a good company with good jobs here in the US.
jchallis··on San Francisco is one of CA’s most conservative cities when it comes to housing
Wife works in pediatric infectious diseases in SF. “Community needle stick” is common enough to get its own acronym. They’re the folks that have to make sure junior doesn’t now have Hep A. Super normal.
jchallis··on Facebook Disabled My Account After I Criticized Them
I find his passion for quitting mainstream social media confusing if he is posting on mainstream social media. How do we know that Facebook wasn’t trying to help ?
jchallis··on Ask HN: How to increase SWE salaries in Europe?
One option is to emigrate to the United States, driving up pressure on the engineers who remain. My near-term ancestors all left Germany due to poor wages and a tendency for Bismarck to sacrifice draft-age men in wars, and while moving to the US helped their own status it also did a bit to increase pressure at home.
jchallis··on St. Benedict’s Rule for Monasteries (516)
Atheist fan speaking up for Benedict and his rule. My education was entirely organized by Benedictine nuns who internalized this rule and lived it daily. The focus on the importance of daily discipline made a big impression on me. Like the military, see an organization make short term sacrifices for longer term objectives made a big impression on me and how I spend my time.

Ora et labora.

jchallis··on Google told its scientists to ‘strike a positive tone’ in AI research
I’ll grant you the boldness, naïveté and arrogance of my 2006 self - he could be an insufferable a$$. But looking from the vantage point of 14 years on I think the statement is accurate and that researcher understood why. There was simply nothing on the horizon that remotely held as much promise as Alain Aspect’s and Serge Haroche’s quantum optics work.

Just because I was a graduate student does not automatically mean I was wrong.

jchallis··on Google told its scientists to ‘strike a positive tone’ in AI research
Every specialty has taboos and learning what they are and how to avoid them is part of being successful with the job. As a physics graduate student I made an impassioned case to a high energy researcher that the money spent on high energy research was low yield and should be pushed to the biological sciences ... suffice it to say he did not take my points on their merits. Upton Sinclair’s famous “ It is difficult to get a man to understand something, when his salary depends on his not understanding it.” applies in the sciences.
jchallis··on SEC charges Ripple and two executives
SEC is pretty far from the tax collecting end of the house. Whatever their sins, greed for tax revenue is not a fair one.
jchallis··on Norman Abramson has died
@dang could we get a black bar ?
jchallis··on Google Sunsets Google Cloud Print
I did not get the memo last year that it was running out.
jchallis··on Google Sunsets Google Cloud Print
In case someone from Google is reading this: - I am a real person who really manages IT decisions for a real company. - I use Google Cloud Print to keep our zoo of devices happily talking to our Japanese printers in the US and Asia. - You made my day hard by killing this product. There is time that I could have spent with my family or on my health that I will have to divert elsewhere to fix a problem that didn't exist for me yesterday. - My memory is long.
jchallis··on Trump to be hospitalized at Walter Reed medical center after Covid-19 diagnosis
My ICU physicians friends are in unanimous agreement that for most patients with advanced symptoms, staying at home with supplemental oxygen and observation is best. This is a sign that more serious and invasive procedures are required.
jchallis··on Interview with Paul Graham
Complete outsider guess : Airtable.
jchallis··on The rise and fall of the industrial R&D lab
CRISPR is at least as big an innovation as the ones you mention. Perhaps you are biased to the areas where you have the most familiarity ?
jchallis··on If founders treated their investors the same way they treated their employees
The chromecast screensaver is the background on the TV in my Airbnb. Multiple guests have told me how much that screensaver makes them feel at home when they travel, and makes the world a little less strange.
jchallis··on Icelandair letting go its flight attendants and shifting their duties to pilots
Cooler. Some folks refer to this as an Eskimo, a non PC term for the Inuit.
jchallis··on Ask HN: Recommend a maths book for a teenager?
Polya's How to Solve It changed the way I thought about learning mathematics. His treatment of random walks in one dimension (eventually all walks return to the same point) vs three dimensions (where they can escape) really affected my mental model of the world.
