Apps are deceptively easy to make.

Great apps hide all that complexity behind the scenes.

TIL Boehm (yes, that guy, of Boehm GC fame) wrote the android calculator app and went through some reasonably advanced math to get it right.

“With this representation, they're in the sweet spot:

All the digits shown on the screen are always correct. And they almost never show more digits than necessary.

A "computer algebra system" would have accomplished a similar goal, but been much slower and much more complicated”

Hasnain says:

“Cornish views Compact as a “low-probability, high-reward” proposition. “If I had to bet, I don’t think they’re going to find anything,” he said. “But the question is so important,” he added, that it ought to be explored “to the fullest extent.””

Hasnain says:

“Noether was an assistant in name only. She was already a formidable mathematician when, in early 1915, Hilbert and Klein invited her to join them at the University of Göttingen. But other faculty members objected to hiring a woman, and Noether was blocked from joining the faculty. Regardless, she would spend the next three years prodding the fault line separating physics and mathematics, eventually setting off an earthquake that would shake the foundations of fundamental physics.”

Hasnain says:

“Bethe ansatz methods show up in so many places, said Pedro Vieira (opens a new tab), a professor at the Perimeter Institute for Theoretical Physics in Waterloo, Canada. “It seems like nature appreciates beautiful things.””

Because of course

“The doge.gov website that was spun up to track Elon Musk’s cuts to the federal government is insecure and pulls from a database that can be edited by anyone, according to two separate people who found the vulnerability and shared it with 404 Media. One coder added at least two database entries that are visible on the live site and say “this is a joke of a .gov site” and “THESE ‘EXPERTS’ LEFT THEIR DATABASE OPEN -roro.””

Hasnain says:

Gotta love new breakthroughs. This was really cool and interesting and I’ll have to read the paper

“Farach-Colton, Krapivin and Kuszmaul wanted to see if that same limit also applied to non-greedy hash tables. They showed that it did not by providing a counterexample, a non-greedy hash table with an average query time that’s much, much better than log x. In fact, it doesn’t depend on x at all. “You get a number,” Farach-Colton said, “something that is just a constant and doesn’t depend on how full the hash table is.” The fact that you can achieve a constant average query time, regardless of the hash table’s fullness, was wholly unexpected — even to the authors themselves.”

Hasnain says:

“ARRAF: It was really surreal because you don't see anything living in that part of Deir al-Balah, which has been heavily hit. I mean, really, it - from what we were seeing, it was just rubble. And it's important to note that Israel prevented us, according to the Jordanian authorities, from taking photographs on the ground of what we were seeing. The only thing we could take photos of once we landed were the buffer zone and the helicopter. But to actually see it real, in real life, was really unreal.”

Hasnain says:

Lots to ponder from this one. I think I’ll come back to this a few times to internalize it. I have various somewhat conflicting thoughts:

* that was a simpler time. tech was a little less evil and more altruistic back then
* I really really resonate with the point back then about fewer people being in tech just for the money
* giving back seemed to be a very common theme, contrasting with the FIRE movement right now
* the avenues one can go into after a successful tech career are pretty much everywhere
* I would love to see a follow up that 1) profiles these same people and 2) profiles folks from the latest set of IPOs
* I wonder how perceptions of the tech people both themselves and in the communities around them have changed
* even without having struck gold things have changed so much with layoffs (and just general poverty)

“Seattle isn’t the only center of newly minted wealth out West. Silicon Valley, the software lodestone 30 miles south of San Francisco, has also produced its share of cash-outs—men and women, most of them still in their 30s and 40s, who made a ton of money off Internet start-ups early in the game and headed (often literally) for the hills, climbing Mount Rainier, trekking in Nepal, watching the sunset from their redwood decks high up in the Santa Cruz Mountains. Because of who they are and where they come from and the way in which they became rich, they’ve spawned a social revolution of such magnitude that it is transforming entire sectors of the West. Unlike people in the ­financial-­services industry, who end up as bond traders or bankers because they want to make a lot of money, “Microsofties” made their wealth serendipitously; for the most part, they tended to be from academic backgrounds—geeky, creative, interested less in striking it rich (until recently, when the Internet got to be like the Gold Rush) than in devising innovative software programs.”

Hasnain says:

Gee thanks bruh. Good luck to my friends still there.

“She also added that Meta's offices would be open on Monday, but anyone "whose job allows" was allowed to work from home and have the day count as "in-person time." Meta currently follows a hybrid schedule, requiring full-time employees to work from the office three days per week and two days remotely.”

Hasnain says:

Great writeup as always from cloudflare. I liked this in particular as it called out one of the layering violations that’s not always obvious when working on low level infra; you have to audit all your dependencies to make sure you don’t depend on yourself being up somehow

“>On-call attempts to re-enable the R2 Gateway service using our internal admin tooling, however this tooling was unavailable because it relies on R2.”

This is gonna kill drop shippers right? And I’m assuming also hurt meta/google ads (temu spends $3b/yr on ads) and amazon in general.

“Known as de minimis, the rule waives import duties for small packages valued at less than $800 shipped into the US. Originally intended to exempt personal gifts and other items that Americans send home from trips abroad, it has since allowed foreign businesses to more easily sell goods to US consumers without needing to worry about paying import taxes. The number of de minimis packages has soared in recent years as the ecommerce market has become more global, making it difficult—if not impossible—for Customs and Border Protection to keep track of all the parcels flowing into the US.

According to the CBP, over 1.36 billion de minimis packages entered the US in fiscal year 2024, almost 10 times the number in 2015. That amounts to 3.7 million packages per day on average—many of which are now subject to scrutiny at the border for the first time.”

Hasnain says:

Welp. At a loss for words.

At least he has been honest about the destruction compared to Biden. That is the only silver lining in what is one of the most depressing moments of our generation.

““I mean they’re there because they have no alternative. What do they have? It is a big pile of rubble right now,” Trump said moments before hosting Netanyahu for Oval Office talks”

Hasnain says:

“It feels pathetic to even have to write this, but right now someone, somewhere needs to fight for something. To stand for something. To match the anger, fear, and sadness we all feel. Because this defeatism, nihilism, and just plain fecklessness from Democrats in the remaining time we have, if we even have it, to save everything we care about is utterly exhausting.

There are many reasons why I am launching an exploratory committee for a bid to the U.S. Senate, but something I’ve thought a lot about is that all these people being so thirsty for the title of “senator”—either in holding onto it for decades too long or striving to attain it—has, in practice, been disqualifying. Wanting to be a senator for the sake of being a senator has given us a collection of people who stand for little other than their own egos, who grow increasingly out of touch with any community but the cohort of 100 people who also share their title, and who cannot effectively serve as reflections of or advocates for the values we prize most.”

Hasnain says:

The style of writing echoes stuff that I’ve seen written about other countries a lot so this was … jarring.

“I’ve long believed that the American media would be more clear-eyed about the rise and return of Donald Trump if it was happening overseas in a foreign country, where we’re used to foreign correspondents writing with more incisive authority. Having watched with growing alarm the developments of the last 24 and 36 hours in Washington, I thought I’d take a stab at just such a dispatch. Here’s a story that should be written this weekend:

…

With rapidity that has stunned even longtime political observers, forces loyal to Musk’s junta have established him as the all-but undisputed unelected head of government in just a matter of days, unwinding the longtime democracy’s constitutional system and its proud nearly 250-year-old tradition of the rule of law. Having secured themselves in key ministries and in a building adjacent to the presidential office complex, Musk’s forces have begun issuing directives to civil service workers and forcing the resignation of officials deemed insufficiently loyal, like the head of the country’s aviation authority.”

Hasnain says:

““We have the power to turn the tide if we want to,” said Oona Hathaway, a professor of international law at Yale. “But at a certain point, the rules are going to become so eroded that it’s going to lose all legitimacy, and the United States is going to lose all legitimacy. We’re going to find that we’re going to be past the point of no return, and those rules are no longer going to be salvageable. And I think that would be a real tragedy.””
