jakelarkin··on Google's interview system: it's not about solving the problem
"its not about the problem" but if you cant correctly code one of these 200 algorithms on a whiteboard in sub 15 minutes while under extreme stress youre not getting an offer either.
jakelarkin··on Bussed out: how America moves thousands of homeless people around the country
we've rebuilt like 15 countries (after bombing them) in the past ... somehow its totally impossible to temporarily house a fractional percentage of people in our country and make sure they get a job or their meds instead of addicted to heroin

theres so many bs political excuses; bad zoning, bad building regulation, bad union rules, bad health regulations, bad drug laws, civil legal liability, cost of Rx drugs ... as if government doesnt have have power to fix those things. it's a feigned helplessness because the poor inherently have no political leverage/value to those in power.

jakelarkin··on Bussed out: how America moves thousands of homeless people around the country
this is the Nash Equilibrium type problem that exists with US federalism and extreme poverty. Cities just ship people around hoping to reduce their share of cost, while the homeless just become more physically sick or addicted, and mentally traumatized, so they become more costly to care for in aggregate over a lifetime. Everyone is worse off. It would be so much simpler, cheaper if society just got people back on their feet as quickly as possible with focused care & rapid re-housing.
jakelarkin··on NY Man Arrested for Cutting Wires to Red Light Cameras (2016)
anybody ever been to Milbrae? It's a tiny town with no courts and no police of its own. The cameras at intersections around the BART station make $millions for the city, mostly for vaguely marked and unnecessary no right turn on red.
jakelarkin··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
probably the processor-memory bus. GPUs have wider ones
jakelarkin··on The iPhone XS and XS Max Review: Unveiling the Silicon Secrets
Apple CPU Architecture excellence is nothing short of amazing. iPhone XS A12 processors are 2x or 3x the speed of a Snapdragon 845 (Pixel 3) and have lower power consumption. For these benchmarks they're approaching consumer desktop CPU performance, which typically draw 40-50 watts, using only 4 watts in the A12. https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-re... …
jakelarkin··on A Nobel Prize-winning physicist sold his medal for $765,000 to pay medical bills
the question the article raises is not whether theyre paid their worth but rather whether theyre dying paupers

I looked up my friends PI at Berkeley. (no Nobel) $300k

pension 50-75% of salary + retiree healthcare benefits

hard to say someone in that position is going to end up destitute unless they make terrible life choices.

jakelarkin··on A Nobel Prize-winning physicist sold his medal for $765,000 to pay medical bills
sensational headline ...

tenured professors are the top 1% of academia and they have a pension no?

maybe he sold it to live out his final days with premium care.

maybe they decided his surviving wife would've rather had a liquid estate instead of a shiny medal in a closet.

jakelarkin··on Verizon Says 44,000 Managers Qualify for Company Buyout Offer
what do they all do? I imagine regional/vertical sales or procurement roles from the before-internet scale era?
jakelarkin··on Commuting by Bicycle is down?
Anecdotally I've seen many people stop biking because its not safe and the risks become apparent to them over time. 5 people I know have been seriously injured biking in San Francisco. When you consider the risk of getting door-ed at 15mph or getting haplessly mowed down by blind merging open-wheel trucks, it's quite physically dangerous. Until we have a broad deployment of protected bike lanes, its just not worth the risks.
jakelarkin··on CEO’s Plan to Save Sears Would Hand His Hedge Fund $1B
its little-stated due to the massive fiscal and political implications but there's a belief among some of the better investment professionals out there that the past decade of 1) low baseline interest rates 2) large run up in stock multiples, 3) proliferation of index funds ... will depress long-run stock total returns into the 4-6% range for many decades.
jakelarkin··on NewSQL databases fail to guarantee consistency and I blame Spanner
won't batching transactions increasing the failure rate by a multiple of (batch size)? how should users reason about that tradeoff?
jakelarkin··on Equifax IT staff had to rerun hackers' queries to work out what was nicked
security by obsolescence is a thing too
jakelarkin··on Airware is shutting down after raising $118M
this is my concern as well. on the hardware side, a Chinese startup can iterate faster & be the lowest cost producer. if design, UX, software, marketing is on par with SV/US competitors. SV is toast (in that industry)
jakelarkin··on Airware is shutting down after raising $118M
so it seems like Drones is one of the first big nascent industries, SV utterly lost to China b/c of their dominance of manufacturing?
jakelarkin··on Single-family homes cover almost half of Los Angeles
it is relevant because people keep making an awful argument there's not enough water for people to live in cities (LA, SF) , when the taxpayers of the state are literally subsidizing half-dozen monster dams & aqueducts so a commercial enterprise can take vast majority of the available fresh water and use it to grow crops like rice or almonds in the California desert and sell them abroad.

jakelarkin··on Genoa Bridge Collapse: The Road to Tragedy
the (old) Bay Bridge serviced trains until the 1960s. perhaps the design had higher loads & structural requirements due to that use.
jakelarkin··on YouTube and Netflix ‘Throttled’ by Carriers
lol. do you really think "Comcast Business" magically upgrades the lines or gateway hardware that serves your home? its just $200/month for slightly better reps, who still can't do jack about how the network drops your traffic.
jakelarkin··on F-35 Program Cutting Corners to “Complete” Development
F35 isn't so much a fighter jet as it is a political graft and jobs program, and in that light it's a smashing success.
jakelarkin··on Pilotless Emergency Services Helicopters Coming to Silicon Valley
an autonomous helicopter startup doesn't have unions with collective bargaining agreements (contractually obligating them to have at least 1 human operator).
jakelarkin··on The Future of Notebooks: Lessons from JupyterCon
I understand why they became popular, but as a software engineer considering how they work, I am just full of disappointment. we're going to spend the next ten years re-inventing every single software engineering best practice for jupyter's weirdo environment.
jakelarkin··on End Stock Buybacks, Save the Economy?
most taxable investors strongly prefer buybacks. capital gains from the equity appreciation are taxed at no more than 20% vs whatever your income tax rate is which can be 25%-50%.
jakelarkin··on Apple and Google Face Growing Revolt Over App Store ‘Tax’
If the app is a singular product that only exists on mobile, then fine you bake the Apple/Google tax into your price.

for content subscription businesses that are multi-platform its a bit of an absurd situation. You can't really charge 50% more on mobile platforms. Depending on where your user randomly decides to sign up your revenue and lifetime value of that user is suddenly 2/3rds of what it otherwise would be, despite costs being the same.

jakelarkin··on Internal documents reveal the grueling way Tesla hit its 5,000 Model 3 target
2,651 hours/week * $30/hour = ~$80k/week. on a volume of cars that brings in $200m/week. so what? its a minor inefficiency.
jakelarkin··on SEC Charges Rothenberg Ventures in Fraudulent Scheme
I wonder if this precocious racket will pay out over Rothenberg's lifetime vs. just banking his pedigree and network on some boring low risk career track. He's currently ahead a few million but his reputation is toast.
jakelarkin··on Los Angeles to Use Body Scanners at Transit Hubs
wearing a stiff jacket or carrying a backpack full of groceries on public transit? ...

prepare to add 30 minutes each way as you're flagged for "secondary screening"

driving your 300hp, 3 ton SUV with 70 cubic feet cargo space full of whatever? ...

all good. free parking at your destination.

jakelarkin··on Vanguard Warns of Worsening Odds for the Economy and Markets
people are greedy. they vote for tax cuts when the economy is doing well.
jakelarkin··on Mark Zuckerberg Is Totally Out of His Depth
Mark is 34. Sure must feel good to be all pedantic about his maturity, but that's not actually the problem. The problem is that the CEO of Facebook or Twitter, whoever it is, is in a Catch-22, they can't solve the disinformation/hate-speech/trolling problem without massively increasing costs on moderation, decimating some growth/engagement metrics and in the process destroying a ton of "shareholder value". If they don't solve the content problems, the platform will slowly die anyway as users start to flee the toxicity. So we're all hanging on as these guys try to awkwardly walk some impossible to find line between the two paths. The last FB earnings were a step in that direction but barely an inch, and things will get much worse.
jakelarkin··on US housing market hit a ‘significant slowdown’ in recent weeks, Redfin CEO says
if youre paying 20% of your income to student loans, buying a house isnt exactly the best play. Student loan interest is a scam. Dig deep and pay that jam off as quickly as a you can.
jakelarkin··on US housing market hit a ‘significant slowdown’ in recent weeks, Redfin CEO says
last years appreciation, the lost deductions, rising rates have really stretched the limits of demand. how many households are really out there who can afford a 10k/month mortgage or 300k down payment that you need for a house in upper middle class parts of Bay Area or Seattle.
