> What he is saying is that if you make $100k in Houston and $250k in SF, the extra $150k is tax entirely at the higher rate.

The part above $128K is actually taxed at a lower rate; crossing the Social Security maximum taxed earnings level (and thus losing 6.2% in marginal tax on income) more than makes up for the 5% higher marginal income tax rate.
You might have been looking at organic eggs. I often buy the 5 dozen eggs at the SF costco and it’s definitely under $10.
Know of any good linters for Helm charts / k8s yaml files by chance? I haven't found much in this space yet.
My point is that the two problems are quite distinct. This is not a small change to how the problem is being solved, but a complete change of the problem itself. Further the change significantly limits the feasibility of the solution, which is not sufficiently made clear by the authors of the blog post. Casual followers of AI/RL research might think that this is a significant progress, while in fact it's actually a progress on a problem that hasn't really received any attention due its uselessness. I think there may be 1-2 papers which might have experiments on this problem while probably 100s in the model-free problem.

Thanks for your analogy though. I agree that it's better than mine. I was only trying to give a rough idea, but I'll use your analogy if I have to now. :)

I'm not sure what that first sentence means, but that seems like a bit much of a response for an interview...

A lot of people are "interested in programming" that doesn't make them a good hire, or that they'll ever do the job. I think the interviewer wants folks who can do the job, now.
I heard an article on the radio measuring the proteins in trees. Apparently much of it in the Pacific Northwest forests comes from salmon carcasses that bears fetch from the stream and discard. I have no idea how they'd determine the source. Maybe I was paying attention to the road when they explained.

So if the fish disappear, maybe the forest does, too.
I'm a fan of grouping by cohesion for the reasons the author lays out, but like any principle you need to understand how and why you're applying it. The author suggests grouping reducers, actions, and components by functional cohesion in a React/Redux app, but the point of grouping by layer in this case is to uncouple the layers in your app (UI vs. store vs. actions). In this situation, those layers represent the functions around which your code coheres.

Depends but NO. After running 2 successful companies I was thinking about going back to school and I asked myself the same question but more importantly the staff as me why I would want to go back to school with my real life experienced. They knew of my endeavors. I was applying to get into Boston's most well-known entrepreneurial schools. I sat in on two classes to see what it was all about. I felt like I was in a room with high schoolers. It was total cake. I answered the questions that most couldn't. Felt bad because I had to set the teacher straight a couple of times as you could tell he wasn't doing much outside reading textbooks. At the end of the course, the professor asked if I'd like to give lectures during the semester. I said not right now. But I got the answer to my initial question.

Good point. Not sure how well currency burns, but ...NONE of it has ever showed up in circulation. Now...what would be really crazy is if all of a sudden a twenty gets passed at a White Castle in Nevada, and all the alarm bells go off, and suddenly we're all reevaluating everything. Personally, I hope he made it.
Depends what you'd classify as good real estate. Sure La Jolla and Coronado are pricey and if you want acrerage you have to move way inland (and deal with the heat), but a half hour commute and $250k a year salary will get you a beautiful home in a great neighborhood.

There is no way you would need a second income for you and your family to live very well on $250k in San Diego.

That said a boat does get you pretty great sea views! I have a friend who slept on his boat near work in Irvine to avoid having to brave the commute back to San Diego during the week. Was cheaper (and nicer) than buying a place up in Orange County.
Tbf, those are trivially not mathematically equivalent (even taking profit instead of revenue). Suppose each contracted worker cost $1/yr in salaries, and there were 1000 contractors/1000 in-house employees. Then without including contractors, the profit per employee is (X-1000)/1000 ~ X/1000, while including it is (X-1000)/2000 ~ X/2000, much lower. Including or not contractors does have a potentially large difference.
Is anyone else annoyed by the native advertising for 1Password there, without any disclosures that they are affiliate links?

Precise arrangements for where/when to meet ("at 10:10, on the corner of mumble and mumble") - because no cell phones. Boston Python, having an unusually large turnout... so someone needed to pull up an extra chair to the conference room table (instead of 150+waitlist) - because so fewer programmers. "Computer" is a job title. Chatting with the elevator operator. Going into downtown office buildings (no staff in the lobby), up and into an office, and wandering around looking for someone to ask where to find the person you're looking for (instead of presenting government-issued papers to be photographed by a security guard in the lobby in order to attend a meetup). As maybe a view of the future: Boston SIGCHI meetups (hosted at Amazon) have lately required signing an NDA to attend. No food or money for dinner in NYC? Head to the clam banks to get both. Manhattan is so noisy you have to yell to be heard by the person next to you... because of the immense flocks of extinct and unGoogleable Christmas Tree Birds (they looked like candle flames decorating trees). Real open-flame candles on Christmas trees. Theft by servants and employees as a commonplace aspect of the relationship. A British officer writing in shocked disbelief, 'the American officer... he, he _talked_ with his men... he asked them what they thought! he really did!'. Egyptian farming villages going on strike, to bring down Ottoman official wrath on intemperate local elites. And on and on. Anyone have favorites?
The SALT tax deduction wouldn’t matter so much if the state taxes weren’t so high in the first place. Additionally, you neglected to mention the doubling of the standard deduction. SALT deductions were essentially the federal government subsidizing state and local taxes. Rather than the feds paying California taxes, now Californians pay those taxes.

The weird, but predictable thing to me is that those complaining about effectively increased taxes due to loss on the unlimited SALT deduction, don’t complain when there is a clamor to raise federal taxes: in fact, most of those people seem to support higher taxes — except when they have to pay them. There is a lot of intellectual dishonesty with many Bay Area voters — they oppose tax cuts, but then complain when they pay higher taxes. California needs to lower taxes across the board but you don’t see Brown or Gavin suggesting tax relief to account for the now higher tax burden experienced by the upper brackets.

The California economy is booming despite the taxes, not because of it. Apple, Google and Facebook are driving much of the Bay Area economy — and they make the majority of their money somewhere else. Local companies thrive because of the large base of high income people that are present because of the massive tech companies. If you took away Big Tech, the high California taxes would quickly become unsustainable. But since everyone around here can afford a Tesla, people seem to think that high taxes are the cause of all of this “success.”

As far as California quality of life, the weather isn’t a result of tax policy and the beaches and mountains also aren’t either. That’s 80% of what makes California have a higher apparent quality of life compared to Houston. The point is, the higher taxes aren’t the cause of a better quality of life compared to Texas. Outside of some obvious places like Cupertino, California schools aren’t particularly good — and Cupertino’s school success is a function of the culture of 60%+ Asians who tend to value education more highly than other groups. It certainly isn’t because of taxes. Washington, DC spends more per student than almost anywhere and yet have some of the worst performance. So when we talk about quality of life — it’s good in California for sure — but it isn’t because of fiscal policy, the 71 degree temperature is a big part of it.

I recently started using https://wallabag.org/en instead of both Pocket and Instapaper. I only rarely used Instapaper and after the EU shutdown I obviously used it not at all. I prefer the app and webpage of wallabag over Pocket, and I prefer the pricing model of their hosting service (not freemium, pay 9 euro/year or don't use the service instead of a free slightly gimped service or a more expensive premium option).

You can also self-host if that's your preference, but I couldn't do that for 9 eur/year.
Have we really progressed memory speeds to the point that reading memory is faster than execution speed on the processor? That just feels wrong.

Your other points make sense. And those would surface as constraints in a similar fashion as a CPU throughput limitation would. I just expect those well before a CPU constraint.

I confess I have not researched CPU speeds in quite a while. Nor RAM speeds. Just surprised to see that the CPU's throughput would ever really be the bottleneck.

Not mentioned here but relative cost of transport is an issue for CO2 - It’s pretty cheap on a nominal basis ($/CF) so transport becomes an issue. Which means it’s a local market, also since it’s a small market - transportation infrastructure hasn’t been built for it.

Point being there is no shortage of CO2 - just a shortage in certain places of demand (at non-exhorbinant pricing).

I could drive much less (I drive below average miles anyway though) and I could get a much more fuel efficient car. I'm not going to get a house with a car charger, so it's unlikely I will get a rechargeable car, let alone one that is fully electric. My apartment complex has one charger for hundreds of units.

Incidentally, there is a charger near the gym I go to and I noticed that it does not display the price in advance. If regulators do not force electric car chargers to show prices like gas stations do, it tells me nobody is serious.

> The Internet had an inherent hard limit on scale and availability simply by the technology that was available at the time.

All technology is limited by what is available at the time. I am nowhere near as bullish as I used to be on “blockchain” but I still think it can have a huge impact. If the internet democratized informatiom the blockchain has the potential to democratize finance and some types of information. The internet had all kinds of crazy scammers during the dotcom era. I think there is still potential here and while the shape isn’t super obvious I think it’s not worth betting against. Im no koolaide drinking crypro cargo cultist but I am optimistic it will solve some problems and be a net positive.

We need to substitute the word "professionally" with more precise terms when talking about our industry. Because if one was to read "professionally" as "at work", then your statement is absolutely false - both the lower bound and average amounts of critical thinking and caring in this industry are extremely low. Even ignoring people who obviously have no clue, I can still imagine Hadoop and other big data stacks being sanctioned by "professionals" in management for buzzword-generating reasons, and implemented by "professional" "engineers" for CV padding reason.
And why does that matter in the context of this discussion? Who is claiming otherwise?
i've ridden single speed exclusively for ever a decade. first as a commuter, then fixed in a velodrome, and now freewheel in the mountains. i recently built my first geared bike since my first "real" bike i got as a teenager. it uses shimano xt di2 2x11 on onyx hubs. it's absolutely silent except for the shifts, which sound robotic. it's pretty fantastic. it was the only way i could get along with derailleurs, as i experienced the same problems you mentioned above. my commuter now has a shimano nexus 3 igh, and that's pretty great too.
Out of interest, what derailleurs and cassette's have you used?

I'm running a 10 speed Shimano XT cassette and an XTR derailleur on my mountain bike and it's amazing. Doesn't really make any sound and the shifting is downright amazing.
I use a Gates belt drive with a Shimano hub gear and it’s nearly silent compared to a chain.
i recently spoke to a recruiter whom i am applied using this feature 1 month ago. recruiter said that he has received 2K and had to go through them. the point here is, easy feature is good for candidates for quickly applying. but candidates are not getting responses faster which implies that recruiter life is tough in sorting through the right ones.
Sorry, I might not be specific enough, I am looking for pointers that show that the person created a new research area, as suggested in the previous comment.

If you list pub list, then I have no idea how to find proof of the fact.

Edit: Below are a bit ranty comments on research style. Please ignore it and provide pointers that show the person created a new research area.

And frankly, the changing of the research areas (security -> deep learning -> blockchain) are a typical symbol of smart people who are good at catching trendy research topics, but never achieved the true top-tier research results. To be specific, such people are absolutely smart and intelligent, but they have a pattern to always latch on so-called cutting-edge topics, and quickly gain high reputation. In the end, their fame and what they do usually does not well match each other.
I would pay for a mobile app that reduces my bandwidth usage during traveling while surfing the Webb away from WiFi.
Oh, it comes up all the time when doing pattern-matching, which many Lisp programs do a lot of. "Anaphoric" macros like AIF [0] are one solution:

(awhen (foo 3) (bar it))

Here IT is bound to the result of (FOO 3), provided that's nonnull. I don't really care for this style, but I see a lot of people using it. I have a macro I sometimes use for this purpose called BCOND ("binding COND"), e.g.:

(bcond ((let ((x (foo 3)))
x)
(bar x)))

The rule is that if the test-form of a BCOND clause is a LET form, the scope of the bindings is extended to the end of the clause. I'm not going to say it's beautiful, but it's quite general; in particular, an arbitrary predicate can be applied, not only a nonnull test, and can involve any or all of the bound variables. I wrote the first version of BCOND in 1980, so I think it's safe to say the need it attempts to address is felt with some frequency.

No racial profile but there is a section about racism in the CS Department. LOL
As the comment above explains, recruiters can do that because we let them do that. I advise people to ask for money to pass a test. The test is the problem's recruiter, not the candidate.

A lot of people say they are interested in programming but very few are. Programming is difficult. More and more people do that for the social position. They should do something they are good at. Most of them who persevere in computers become managers.

If a recruiter isn't able to evaluate someone by talking, he shouldn't recruit people.

The Excel Depression (2013)
The headline is misleading. It says ICOs "die". The actual article says that after 3-6 months, returns from a cryptocurrency are no better than the overall crypto market.

This is like saying after 6 months of an IPO, the stock does not outperform the S&P 500. It doesn't mean the IPO is dead, or the stock is dead.
Taxes. A doubled income in California isn’t a doubled income. It’s much less: higher tax bracket, state income taxes. What needs to be compared is the after tax income. Because it sure isn’t doubled. Even if you add it property taxes — tax on a Houston $500k house is going to be less than taxes on an equivalent $2 million house. The median prices of condos in San Francisco is almost $1.4 million. $1.4 million could buy you a grand house in Houston. A nice condo might cost $350k. Because, even if you double the income, your post-tax pay isn’t actually doubled. Adding housing into the mix (even ignoring taxes) and the math is still rather difficult because houses cost far more than double what they do in Houston.

That’s a big difference when you talk about doubling income. Taxes and housing; that’s the problem with California.

>the rapid rise of the rapid rise of credential stuffing attacks

Maybe I was wrong but I always thought that was the "point"...

At least in the sense that as far as profitability goes the point of hacking or gaining access to a list of hacked passwords from say a boring site like some image sharing site was that you then take that and use it to do more nefarious things like access banking stuff, more sensitive identity related things, spying, etc.

Obviously there are folks out there hacking away for their own enlightenment or fun, but ultimately anyone looking to do more than that, I always thought the point was credential stuffing all along, otherwise who cares what someone's Flickr username and password is?

Seems like a missed opportunity. Millions of rolling batteries frequently plugged into the grid could be an energy storage pool to help balance fluctuating demand and supply. Especially from renewable sources.

For this to work, it would require government co-ordination of infrastructure, incentives and regulations around feed-in tariffs.
