Based on my experience, it's the most typically seen bottleneck. But bottlenecks change over time. You notice slowness somewhere in a website action and you dig into it. Sometimes, it's a new database table that isn't optimized with correct indexing. Sometimes, you end up doing an n^2 or n^3 operation on the backend (sometimes it's on the frontend). Sometimes, you're data is growing at a speed that your single monolith database isn't cutting it and you need to shard or consider a different type of storage.

Bottlenecks change all the time. You fix one, and now suddenly, the bottleneck lies somewhere else. There's almost always a bottleneck somewhere. A database bottleneck is relatively common, though.

From my experience, the bottleneck is mostly at some type of Big-O relevant scale in the code or database that using java vs ruby vs python doesn't make a huge difference.

However, if you're in a situation where speed is absolutely crucial - like high frequency trading (where milliseconds mean millions of dollars) - well, that opens a completely different can of worms.
Interesting read. For someone who has the time and patience to gather data against the author's arguments, I would highly recommend going to the source of the data. SoftBank's financials - FY 2018-19[1]. I had a quick skim at the segments of the company and they have some interesting sources of revenue/profit which could provide some cushion: ARM, SoftBank itself (telecom), Sprint!, Yahoo Japan.

Can someone more experienced than I am on financial matters check if they're in deep shit as the article suggests?

One thing I found really eye-opening about this show is that it really showed both the bad side as well as the good side of Soviet culture.

It is unquestionably the case that Soviet authoritarianism and disregard for safety is to blame for what happened. But one thing that is often forgotten, but I think the show highlights, is how well the aftermath was handled.

Yes, Pripyat should have been evacuated earlier, and yes, they should probably have notified the rest of the world sooner. But think of this: the Soviet Union mobilized 500,000-750,000 people to clean up the enormous exclusion zone. They got thousands of men to don full lead suits (that could only be used once) to run out on a roof for 90 seconds each to throw off radioactive rocks one at a time. They built the enormous containment structure in just a few months, arguably the greatest feat of civil engineering in history. One of my favorite scenes in the show is when Legasov says he immediately needs 5,000 tons of sand and boron to cover the core, and Scherbina basically just walks off and gets it for him (along with a full fleet of helicopters to drop it).

All of this was necessary, and they did all of it, no matter the cost. This was unquestionably a real strength of the Soviet Union. Can you imagine that the US would have been able to respond like this? Either today or in the 80s? I can't. With the exception of wartime mobilization, I can think of almost nothing else that even compares. There are few (if any) societies in history that could have done what the Soviet Union did in response to Chernobyl. In a way, the world is lucky it happened there and not somewhere else.

That largely depends on the usage patterns of the app in question.

Write operations can be particularly expensive, read operations much less so, especially with application-level caching. Even as for write operations or notoriously expensive read operations such as full table scans modern RDBMS are optimised to a degree that for most applications database performance shouldn't be an issue.

While traditional hard drives competed with the network for the title of "system component with the lowest bandwidth" (see http://www.cs.cornell.edu/projects/ladis2009/talks/dean-keyn...) accessing data on an SSD is way faster than accessing a resource via network.

So, today the technical bottleneck (as in "component with the lowest bandwidth") in a typical web app system architecture is the network.

I'm referring to 'capital' in the economic sense, not financial sense.

Here's the Wikipedia definition:

>>In economics, capital consists of an asset that can enhance one's power to perform economically useful work. For example, in a fundamental sense a stone or an arrow is capital for a caveman who can use it as a hunting instrument, while roads are capital for inhabitants of a city.

and

>>Capital is distinct from land (or non-renewable resources) in that capital can be increased by human labor. At any given moment in time, total physical capital may be referred to as the capital stock (which is not to be confused with the capital stock of a business entity).

Increases in capital essentially mean increases in automation.

>>If you have a job which can be automated at a cost equivalent to a $10/hour wage, it doesn't get automated when the wage is $9 and does when it's $11. The money doesn't inherently come at the cost of some other automation, it may (and if the other automation is profitable, more likely does) come from selling some bonds or other assets you own, or by borrowing it from a bank which just creates the new money from nothing as banks do.

Not inherently, but generally. There's generally an opportunity cost. If the business has to pay $11 instead of $10, that extra $1 represents more resources being expended on accomplishing that task, which leaves less resources for other things.

Yes there are always situations where some extra cost leads to a business or a combination of businesses unlocking productivity that was otherwise dormant, but there will be cases of the opposite, of an extra cost exacerbating wastage, beyond the value of the extra cost.

You can't assume that an extra cost will lead to more efficiency gains than efficiency losses. The reasonable assumption is that the two variables will balance each other out, and on average, a $1 an hour increase in the cost of accomplishing a task will mean $1 less resources going into other productive tasks.

>>A lot of these things are actually good -- if people sell real estate to buy automation equipment then housing prices come down.

That's an overly optimistic and unsupported assumption. The profitability of holding real estate will not go down relative to investing in manufacturing as a result of manufacturing costs increasing.
The key bit is at the end:

>It also reveals that China Telecom, a major International carrier, has still implemented neither the basic routing safeguards necessary both to prevent the propagation of routing leaks nor the processes and procedures necessary to detect and remediate them in a timely manner when they inevitably occur.

So basically a lack of external pressure combined with a lack of caring about preventing this.
imho, none of the mainstream languages are in such a state. from venerable C on one hand to Python to Rust to Erlang, even Fortran ! every single one of them is changing.

and, once again imho, this state of affairs is _exactly_ right as well. newer h/w, a deeper perspective on what works and what doesn’t all contribute significantly to this flux.

embrace the change :)

That's completely up to you; you need to create your own bubble (for better or worse).

What I find bad is that there's no "circles" concept (both incoming and outgoing). While the "incoming" part is not a problem for me, the "outgoing" part is (example: posting slightly conservative views will cause tech snowflakes among your followers to be upset; I'd like to restrict outgoing tweets to a subset of my followers).

RTP is central to three counties--Wake (Raleigh, Cary), Durham, and Orange (Chapel Hill). There are a lot of good public schools, but it depends a lot on which county and city you live in. And of course school district has a big impact on housing costs. There are also a number of charter schools, where enrollment is usually based on a lottery.

As a place to work, there are plenty of good software jobs in the area. I would group in not just RTP but also downtown Raleigh and Durham. As an employer, it's difficult to find enough developers to fill roles. There are technology hubs all up and down the east coast (Atlanta, DC, Richmond, etc.) which RTP competes with for talent.
You're right, but for most people writing C#, the developer time saved by Linq (being easier to read and understand quickly) is much more valuable than the tiny amount of CPU time that's lost.

Fun story, AT&T forced our hands to get off our PRI (voice T1) and move to their fiber service. They also insisted that they have a dedicated phone line installed so they can dial into their modem in case of circuit failure. We can’t buy a cooper phone line from them, so it gets routed over the same fiber circuit and goes to a digital to analog device back to the router. I don’t think one hand talks to the other over there...

The Internet and economy are both not machines, but networks of machines interacting by some agreed-upon protocol (Internet Protocol in the internet's case, lots of tangled multinational foreign legislation in the economy's case).

Break the networks down far enough and you'll find the individual component's owners/creators. Even the protocols were created by specific people (and for specific reasons! The design philosophy of the internet protocol is pretty interesting reading) even if those people are no longer involved in the operation of the networks.

> The fact that we want to get each other off at all is driven by evolution,

This begs the question. Gay sexual desire is a counterexample to this claim.

> a species that doesn't have an urge to get each other off goes extinct pretty quickly.

Evolutionary considerations may set boundary conditions. It doesn't follow that the sexuality that humans in fact have has an evolutionary explanation.

There's a dilemma here. If you're going to paint a picture of evolution as a ruthlessly fitness-optimizing process, then you have to take gay sexual desire seriously as a counterexample.

If, on the other hand, you accept that evolutionary theory per se only rules out extreme possibilities (e.g., a completely asexual species that reproduces sexually), then you also have to accept that the specifics of human sexuality may not have any explanation in evolutionary terms.

>Really, you think quest for knowledge is at all comparable to the 2000 years of active persecution?

The persecution of gay people continues. Non-religious bigots will often justify it on alleged evolutionary grounds ("it's not natural"), just as religious bigots will often justify it in terms of Biblical proscriptions.
Yes, the database is still a bottleneck, but that depends on the size of the data and what you're querying for. If your data fits comfortably in memory (and so do any operations you perform over it), then performance is not really an issue. For many businesses — probably the vast majority — all the data could just sit in memory.

It's interesting that this society is matriarchal and non-monogamous. Bonobos, our closest animal relatives, are also matriarchal and non-monogamous.

For me, realizing sales is part of the honest value I’m providing was a real game changer. It’s not about closing the deal. It’s about having something of real value, and honestly educating potential customers on when they should consider buying and when they would not be a good fit for the product.

This is just as important service as building the product itself. And what the article describes as sales anxiety can be an asset. Introverts are more likely to be in a position of listening and not just pushing the product to do hard sales.

The book “To sell is human” really changed my perspective, as the author makes the point that the best sales people primarily want to serve others, not just trick people into buying something they don’t need. Good sales is about communicating and matching up needs to value in an honest fashion. Not “ABC”

The title gives a connotation about the article's contents that is not actually present in the article. While the article works just fine at giving the broad strokes for how to acquire wealth, it makes no effort at providing direction for how one might do it in a riskless fashion.

I feel like you're misunderstanding that quote as well.

It's supposed to be "Not all who wander are lost" and it refers to loners, wanderers, vagrants and explorers that never settle down and 'plant roots'.

The idea being that there are plenty of people that exist like that and enjoy that way of life. Other people with families and steady jobs tend to look at them as if they are 'lost', without truly understanding what it is to walk the earth.

Have there already been noticeable changes in investments in the valley since the last big round of unicorn IPOs?

Since we can assume many VCs got a lot of cash back in a relatively short time I guess they will either double down and reinvest even more in tech/startups - or they will stay out of tech for the foreseeable future.

Or is it too early to tell because new funds would have to be set up first?
Persistence is still slow, but is no longer a major bottleneck. SSDs are faster, but io and network is still slow.

What has changed it is much easier for the client to be continually in touch with the server so that by the time the next "page" is loaded all necessary data has been retrieved.

This way the database is no longer the same obvious bottleneck.
