>> "Let’s say we have 1000 records in our film table. To find “Academy Dinosaur” our database will need to do 1000 operations (comparing the title in each row)."

> No you don't. If your table is sorted, [...] on average, to find any title, you will need n / 2 operations (so not 1000, but 500, in this example - this part is plain wrong as it's written). Of course, n / 2 is linear in n, so the complexity stays the same.

If something is sorted, search happens in O(log N) which is not linear: start with compare at N'=N/2. If "less than", go to N''=N'/2; if "greater than" go to N''=3N'/2. Etc.

If the data is not sorted, then yes, you will need N lookup operations.
This. My friends'kids constantly pick up my phones and ask to game on it. Sometimes they don't know what they are doing and decide to spend my in game money ( Like Stars or Gems or something ) to play.

Having a $10 Subscription allows them to mess around with all the games without me having the hassle to think and worry about what they do with it. I am not a causal gamer, but I see this will have lots of appeal. 10M sign up would be $100M per month.
Investments are not part of your operating income. Your income only consists of flows that accrue over time. If you make a $1200 investment, the expense associated with the investment is accounted for by spreading that expense over the lifetime of the asset. For a 20 year asset, this would become a $60 expense per year.

It's not like it's a new thing that businesses need to invest to to acquire customers. The entire science/discipline of accounting exists to provide accurate metrics of business performance. Its ridiculous to say that "profits are a bad metric" because of this.

Also, WeWork is not a software business, since they do not sell software. Why would those metrics apply here when all their money is made through leasing office space?

Perhaps ptersaurs could also use their long necks and big heads to start their center of gravity higher before launch?

Dropping a mass (head/neck) from higher up while launching keeps the center of gravity about the same requiring much less effort for the critical "get off the ground" phase.

The Local Persistent Volumes are not quite ready for things like DB workloads. They still require manual work to be done before they can be used. So if you plan on using them you need to configure your servers and manually create the PV objects, and you need to do some configuration to make sure disks are the correct sizes since there is not dynamic packing for smaller DB's.

There was talk earlier about using LVM to be able to really provide a Local PV that is like the network attached PV's, but it doesn't look like that landed yet
What do you mean, "Like England"? Healthcare in the UK is substantially cheaper than healthcare in the US.

I'm F4HDK, the creator of these NPR modem. The unprotected telnet access is only for local management, especially when you connect only 1 PC to one NPR Client modem.
If you need security for accessing configuration/management features of the modem, then you can deactivate the telnet server inside the modem, and put a R-Pi dedicated for that feature, which will be plugged locally to the modem via USB. Then you access the R-Pi via SSH. This is explained in the "advanced user guide".
But of course trafic will be kept unecrypted, due to amateur-radio regulations. (telnet is only for management-configuration).

I met Michael David Crawford (MDC) for the first time when he was mickeyed up in the San Louis Obispo (SLO) County Jail. One of the other kuro5hin.org users had figured out that MDC hadn't been posting because he was in jail. He'd headed south from the Portland area, wrecked his car in SLO, and was arrested for being a nuisance at McDonald's -- probably for helping himself to free ketchup.

They dropped the charges and released him the day after my jail visit. He'd been locked up for several months, also spending time at the Atascadero mental hospital [1].

The criminal justice and mental health systems certainly did NOT do anything to help Michael with his actual problems.

I told about my efforts to reach out to MDC on kuro5hin.org (k5 diaries reposted on my site):

Selective Electromagnetic Interference - https://www.taxiwars.org/2013/02/selective-electromagnetic-i... - This one had a portion of the letter he'd sent me from jail: "... It really helps to know that I'm not forgotten in here."

Some months later I went to Oregon, and swung through SLO on my way back to Arizona. He'd been living at a shelter, I bought him breakfast and gave him a crossover cable for his laptops (any old network cable probably would have worked).

Sometimes what a person really needs isn't much: someone who believes in you can make a huge difference. He got a job after my second visit... Made some progress at debugging their problem, but then he fell apart again, I don't remember the specifics.

A lot of discussions are around the business side and not the technical. Having the game works across iOS and macOS is something I thought not going to happen before. That is like saying your Xbox Games works across on your PC.

How will the control works? Are they all based on some Middleware engine? Unity or Unreal? Are Apple having a hands in those development ( Finally! )? What kind of support are Apple giving to Game Developers where Apple has for the past 20 years completely neglect them. New Metal API?

The really interesting thing I see for this is a possible other route for game revenue in the future. Instead of paying up front (traditional) pricing or advertising, or cosmetic (or not so cosmetic) in game purchases, you could have two tiers, free and optimized latency for a cost.

Or some combination. Cosmetic in-game purchases aren't necessarily bad, but the amount my son has spent and tries to continue to spend (I strictly limit what of his money he can waste on it now) on fortnite stuff is ridiculous and concerning. A sane middle ground would be helpful.

I just accept that I'm going to miss things. I use an RSS reader to keep up with blogs that I care about and with a couple news portals, and I have certain sites like HN that I visit one or a couple times per day, but I gave up trying to read everything. I've got a life to live, things to do, people I love that I want to maintain healthy relationships with. I'm not a machine for viewing and notarizing things on the Internet.

Before the web and Google and Wikipedia and blogs, simply knowing obscure information could be an advantage. It just wasn't possible for the average person to expose themselves to as much information as we do now. It took work, you had to be active, you had to buy magazines and newspapers and you had to physically go to the library and get to know the reference librarians. You had to learn how to use microfilm readers and you had to take notes or photocopy things by hand. We no longer have to do all that. But now I think taking time away from the flood to develop skills brings advantage.

I'm not a fan of Jaron Lanier and I'm not one of those people who thinks we should all withdraw from the Internet. But we do have to develop skills and information hygiene. You can't eat everything at the buffet every day and remain healthy forever. You have to pick and choose.
Uber has shown great growth in markets during recessions: ex Brazil. The theory is that ridesharing is a driver constrained market, and during recessions, more people drive for uber to make ends meet. Also, people invest less in large purchases (cars) and instead spend more on services with a higher marginal cost (taxi, ride share.
The depth of the readings (1400 pages) and exam question is inspiring.

What's the difference?

I'm not familiar with Python since I'm from Java background. In Java throwing exceptions is costly (like null check is preferred over catching NPE) since exception needs to get stacktrace which involves quite a lot of reflection.

686 Comments,

300 of those are Apple getting too much power and stepping into your payment. And Needs to break up Apple or Google or Amazon or whatever. Not sure why it matters as this is not Apple's first CC, they have had Barclaycard Visa with Apple Rewards as told in the 2nd Section Comment.

200 of those are Apple Card not having the best Rebate, as there are many other cards offering much higher rebate with no annual fees. I mean seriously, did anyone expect Apple to offer the best Rebate Card? No one is mentioning You are basically trading around 1% of your Spending discount for your privacy and Data. Along with better Financial Planning from your Data on Devices.

100 of those are about Visa / Master having duopoly and getting all the money. Well there are actually lots of other companies, transaction fees, cost and Interchange fees involves and Fraud Protection.
This made sense until the last line. If the conclusion was "focus on telling your story well so that people understand the point of your work," I would understand that. But he concludes with "name it, and they will come." So... he's saying that your product needs a good name? I don't get it.
Because not doing so is more expensive and effectively subsidized in itself because road costs aren't factored into transit but track costs are. While tolls offer scalability (more users = more funding) shifting from cars to transit still saves money and reduces traffic.
I think most people understand commodity as things like: iron ore, sugar, rice, chemicals, raw materials.

For example, take a Toyota Prius. Most people would not think of that as a commodity. It also is not a monopoly. If Toyota Prius where a software tech startup, they would be bemoaning the fact that they have become a "commodity" (read: it's become a competitive market where consumers have choice between differentiated goods).
Yes, it should instead be compared to white collar crime. Fraud, perhaps. Wait, is this still an analogy?

>Wouldn't that also be consistent with a finite universe

It would. It is not an unanimous conclusion that "stuff" is found everywhere in the universe and that the universe is infinitely big. However, that doesn't necessarily imply a center or an edge.

The universe might be infinite and unbounded.

The universe might be finite and bounded.

The universe might be finite and unbounded.

If the universe is finite and unbounded, we can go back to the ants on a balloon analogy. As expansion continues (and indeed speeds up) the balloon will continue to inflate, for forever. It is not possible to ever make the trip around the balloon to get back to your starting destination due to the expansion of the universe. The universe and spacetime are the 'surface' of the balloon - there is nothing inside of it, the center is not the middle of the balloon, and you cannot tunnel from one side of the balloon through to another. That isn't to say the observable universe is likely to be the extent or even close to the extent of the actual universe - it is likely still just the tiniest of fractions of the actual universe.

We're probably finite and unbounded, and expanding into nothing. As the universe expands, it creates space where it did not exist.

There's other theories that are reasonable, however. Some posit that our universe is a bubble in a true vacuum, and that there could be other bubbles containing other universes. Those theories are largely driven by the theory of inflation, which is the most accepted explanation as to how the universe expanded so far and so quickly in its early stages. (That's not to imply that the bubble multiverse theory is the most accepted explanation, though - just that most theories relating to bubble multiverses stem from looking at vacuum energy)

We probably won't know for certain in our lifetimes. Intelligent lifeforms might never know for certain.
I've spent at least 11 years working to "take control of [my] impulses" when it comes to sleep and other negative behavioural patterns.

I've explored everything that the mainstream and heterodox medical/psychological bodies of knowledge can offer up, including exercise, diet and a vast assortment of approaches, some of which you can imagine and some of which you can't imagine.

I've had solid success, eventually, but it's taken a huge amount of effort over a long period of time. And I'm in a pretty good position regarding finances, family support and work flexibility.

Others aren't so lucky.

You should tone down the barbed insistence that people should just decide to change. This stuff is hard, and actionable solutions and societal support are very hard to come by for many people.

I believe we're talking past each other. Big O has nothing to do with "actual run time*. It doesn't care what about the number of inputs you have - just that you have them.

Mathematically, if n=1000 then log n is 10. 10 operations vs. 1000 is, theoretically and time complexity wise, faster.

Our disconnect is "actual" vs. "theoretical" and I want to stress again that Big O is purely theoretical. It's a technical adjective.
It will have to be fixed eventually, but it's not that big of a problem (yet) & reworking highway funding is going to be a horrifying & colossal undertaking we'd like to do only once!

To add to the bandwidth characerisation:

Bandwidth has followed an improvement curve since the early days of the internet, though it has slowed down a lot lately.

Streaming movies became viable despite the slowing rate of bandwidth improvement. We had 30 kbps modems in the 90s, then 8 Mbit ADSL1 in 1998, 24 MBit ADSL 2+ in 2003s, 40 MBit DOCSIS around the same times. If the speeds had continued to improve at the same exponential curve, consumers would have 100+ gig broadband by now.

The same is true about datacenters, the bandwidth per compute capacity available to servers has decreased for a while.

Bandwidth is an easier problem than latency, because it's not limited by speed of light.
