jlj··on AWS Boilerplate
AWS Amplify is in a similar space. It supports several frameworks and the development workflows and infrastructure management are built in to the project.

jlj··on The $8M Heist from the Carnegie Library
Or they have the wrong skin color.

Stealing culturally significant items from the public like this case is more similar to graft or corruption, or breach of fiduciary duty. White collar crime. Far from victimless, it hurts everyone.

jlj··on The $8M Heist from the Carnegie Library
> This case really highlights the two-tier legal system that exists in the US.

Like a life sentence for stealing hedge clippers. https://www.cnn.com/2020/08/06/us/louisiana-supreme-court-tr...

jlj··on Warren Buffett traded Goldman Sachs for gold
Inflation wave started in 2008 when the housing market crashed and QE really began.
jlj··on Double Entry Accounting for Developers
I learned from my accounting 101 professor, "debits on the left, credits on the right."

Then later after learning about natural account balances, it all made sense. If an account has a debit balance, a debit increases the balance and a credit decreases it. An asset or expense account has a debit balance.

Credit balance is just the opposite. Liabilities, revenue, accounts. Credit is an increase, debit decrease. (I think equity too but I always have to look it up. Rarely work with equity accounts in my day to day)

jlj··on Ask HN: Is all of FAANG like this?
OP said he's working at 20% capacity for one because the tools and documentation are bad. If fixing those problems increases the team productivity by some non-trivial amount it's a positive data point for a promotion.

At my current co, promotions and job levels are measured by increasing impact at an individual level, within a team, across teams, across orgs, etc. Cutting waste is everyone's job.

jlj··on Ask HN: Is all of FAANG like this?
> I normally work about one day trickle out my changes during the the week. The other days I only open my computer for standup and if I get an IM.

There is a term for this called "sandbagging."

> I don't feel what I'm doing is ethnically wrong, because the company is evidently pleased with my current productivity, but I find it unsatisfying and like a waste of my time on earth.

Sounds like you have a motivation and procrastination problem. Pleasing someone or some organization != ethics.

> The dev tools, docs and tech debt impart such a slow iteration speed

Help streamline how the dev tools are used. Tools alone don't solve for much, they need a solid and frictionless process to follow. Document that process to help yourself and your team. Find some common threads or repetitive issues in the tech debt and fix it without waiting for someone to ask you to fix it. Those kids of work may even help get you promoted and open up more interesting projects.

jlj··on Don't close your MacBook with a cover over the camera
Just use tape?
jlj··on Teach Yourself Computer Science
There is a steep learning curve to go from scripting out some solutions, to understanding good design patterns for production quality code, and to run and deploy an application. I have a non-technical BA degree and it has taken me years to feel competent at building software, and every day I have to push myself to learn new things. And the learning is often "two steps forward, one step backwards." It's not for everyone.

> Rant done, it's just frustrating that people limit themselves like that.

"If I can do it, so can you" isn't a fair judgement. Everyone is different, and CS/programming has many complexities that not everyone is interested in putting in the time commitment to learn it.

For me, with time and experience it has become easier to put a solution together, but it still not easy work and many times I am mentally exhausted by the end of the day.

jlj··on Advice to new managers: don't joke about firing people
The behavior is toxic. It doesn't matter the intent or context. It is passive aggressive, period.

At best, it is someone who is scared to have difficult conversations. At worst, who knows.. I've slowly learned not to try and rationalize what makes people like that tick. It's their issue, not mine.

jlj··on Advice to new managers: don't joke about firing people
> You could call it transparency

Nope. 100% passive aggressive, toxic behavior.

jlj··on Ask HN: Which tools have made you a much better programmer?
For me I get the most benefits from using FP features. I can write one-liners that are easy to read, and replace 10's to 100's of lines of my code.

For a simple example, val newList list.map(function Call(_))

Instead of val1 = functionCall(1) valN = functionCall(N)

jlj··on Swiss companies must pay share of rent for employees working from home
Amazon's Bellevue footprint across to the lake from Seattle is expanding. New development in Seattle mostly stopped since 2018, while some existing projects are still being built and coming online.

jlj··on Dolphins at popular spot miss tourists and keep leaving 'gifts' on shore
There is some evidence of whales displaying gratitude and understanding of a human's intentions to help them. Very moving and interesting podcast here:

jlj··on Apache Drill's Future
SQL can be used as a dataframe, or a hive temp view that can be called from other SQL. That gives flexibility to mix and match SQL and programmatic logic within the same spark app.
jlj··on Patio11's Law: The software economy is bigger than you think
When good enough software solves the right business problem, it frees up resources to solve the next most important business problem. Good enough software runs many great businesses.

The one unicorn I worked for had so much cash to spend, there were at least 3 teams of 8-10 engineers on the same floor trying to solve similar business and infrastructure problems with different combinations of open source software.

jlj··on Hydroxychloroquine Associated with an Increase of Survival in Covid-19 Patients
> There was a non-statistically significant trend towards survival in all groups, which will have to be clarified in subsequent studies.
jlj··on Medium-hard SQL interview questions
> A weakness of these types of SQL questions however is that it's near impossible for the interviewer to provide help/guidance

I've given SQL interview questions quite a few times and like to present a sample dataset or schema, and state a problem statement or expected result. Then I collaborate with the candidate to come up with assumptions, and I give gentle guidance if they are stuck or going down the wrong path.

I'm always up-front with the candidate about not looking for perfect syntax, and I am more interested in their problem solving and collaboration skills than the actual SQL they write.

People who ask ask questions about the data and schema usually do much better than those who jump right into the solution. Just like in the real world where really nice SQL or code doesn't matter if it solves the wrong problem.

jlj··on Jeff Bezos has returned to day-to-day management of Amazon
> This is still far smaller than other pandemics in the last 100 years. > What makes things different..

We are still in the early days of this pandemic. The history of COVID-19 is still being written. No one knows how long we're in for or what the final death count will be.

jlj··on Rt: Effective Reproduction Number of Covid-19
> With COVID by the time you have a negative test result back it’s no longer even relevant.

A family friend died on Friday. His heart went out on him. Big guy on his 60's. He got tested for COVID-19 before he died at the hospital. He and his now widow had some sinus congestion. She couldn't enter to he hospital to be with him when he died. A few days later, his widow got the negative result for her husband. She is alone, scared, dealing with this loss. can't see her kids or grandkids. She can sleep a little better at night knowing that death is not knocking at her doorstep.

Relevant? From a human perspective it is most definitely relevant. Maybe not as much from a epidemiology or number cruncher's perspective but like all expert opinions they are open to interpretation and second opinions. Statistics are easy to cherry pick for whatever agenda is being pushed behind the scenes.

Just like masks were not relevent at first. They were scarce. Suddenly they are relevant for the public to use. I believe this testing scarcity and related lack of any cohesive national mobilization is the biggest failure of our US government. From a public health perspective this dismissal of negative testing is just a way to manage the demand side for testing.

Public health and epidemiology experts have very different motivations than individuals dealing with loss and fear during this crazy time.

jlj··on It bid high and lost. Should Amazon be allowed a do-over on JEDI?
> He still plays the victim every once in a while.

Try continuously. Every problem is someone else's fault, and every success is solely because of him.

jlj··on California, Oregon and Washington announce western states pact
It's really someone who wants to own the success of others and blame others for failures. Zero accountability yet still wanting to call the shots.
jlj··on Was corporate profit growth a bubble inflated by "financial engineering"?
How about taxing corporate stock buyback transactions at a high enough rate to make it hurt, and keeping the money set aside for social safety net and training programs that support the people who are losing their jobs.

History has shown again and again that corporate tax cuts and repatriation schemes go right into stock buybacks and don't trickle down nearly enough to individuals. So tired of corporate welfare.

jlj··on Effect of economic crisis on America’s small businesses [slides]
"these people" are dying in mass and overwhelming the medical system and even the crematoriums. And they deserve to have quality of life and die with dignity and proper care.

I'd rather a strong, comprehensive public health response than trying to economic recovery ourselves out of this problem. IMHO, the economy is a distraction to numb us from the tsunami of ICU patients and deaths to come.

The economy is not sacred, and is cyclical, and needs a good purge and rebalancing every 8 years or so. Recessions reallocate capital to be used more efficiently. After 2008 they were politicized as something to be avoided at all costs.

jlj··on Fulfillment by Amazon suspends non-essential inbound shipments
"The dangers of overcentralization of shopping"

Another perspective: An advantage of supply chain efficiency to get life sustaining goods to people during a global health crisis.

jlj··on Washington governor announces shutdown of restaurants, bars
This is acknowledged in the announcement.

"These are very difficult decisions, but hours count here and very strong measures are necessary to slow the spread of the disease. I know there will be significant economic impacts to all our communities and we are looking at steps to help address those challenges."

jlj··on Soviet radar hidden in Chernobyl’s shadow [video]
HAARP isn't the same type of installation as the Soviet example in the article. It is a radio transmitter, not used for radar.

Alaska had the "dew line" which was an installation similar to the Soviets for detection of ICBM's. It covered the perimeter of the horizon towards Russia. https://en.m.wikipedia.org/wiki/Distant_Early_Warning_Line

Clear AFB in Alaska has (maybe had) an operational radar station that looks very similar to the Russian one. Saw it in person a few times driving by as a kid. Not sure if it still exists or was upgraded with something smaller.

jlj··on Robinhood goes down again, during another historic trading day
There's a buyer for every seller.
jlj··on Ask HN: How do I help my Indian coworker get a raise?
Is OP is asking for help with their own situation? "I have a friend who..." is a common way to do that.

It also brings light to a hard situation that many people may be ignorant of.

jlj··on Ask HN: What are some books where the reader learns by building projects?
That's a lot of 5 star reviews, and a topic I am struggling with right now. Picked up a copy. Thanks, and look forward to reading it.
