for a long time i used a variation of this as an interview question for performance analysis positions at google. instead of focusing on I/O costs i was focusing on cache miss costs, but it's pretty much the same observation at a different scale. it's always seemed like an excellent educational example of the difference between theoretical and practical concepts in computer engineering, such as big-O and turing machine vs. practical problem sizes and hierarchical storage/cache capacities/costs.
There is some debate over just what public services are essential. But I do agree that livable support ought to be available for those who, for whatever reason, can't provide for themselves, or get support from family or friends. That's arguably a major part of living in a society.
Education doesn't make the masses any more difficult to control. And it isn't an improvement over anything at all. That is just dogma.

So, ignoring what Stallman said, article says he thinks that way as a function of the sex he is and his skin color.

I am struggling to see the relevance to the issue.

Is the author saying that if the comments were made by a female of non-white skin tones they would be acceptable, or at least less harmful?

Starts to look similar to place where phrenology is ok, as long as I get to choose which are the good head lumps. You can extrapolate from there.
I mean in the context of block-oriented access, like VM as discussed in the article. That a block-aware data structure performs much better than a block-unaware one isn’t that surprising or interesting, at least to me.

The question is: In the context of a block-oriented store, like a VM system, when is b-heap better or worse than b-tree and variants?

Note, I said “and variants” deliberately because of course plain b-tree is pretty simple. Just comparing O between b-heap and b-tree isn’t enough because B-tree variants can have the same O characteristics, I think.
I have only good things to say about Brother printers. My old laser printer (actually a bigger printer/scanner/copier all-in-one with the option to autonomously scan to email) died just last year after 18? years of service. If I were to buy a printer today, I'd choose Brother again, but I just don't do much printing these days, and it's just a 2 min walk to Staples from my place where they do all kinds of printing, scanning, and photo services.
Sandstorm is one of the coolest pieces of tech I've come across in the last few years. Not just on a philosophical self-hosting level, but also a technical level (capnproto is awesome). I'm working on a product right now that is heavily inspired by Sandstorm.

In my opinion the one thing that makes it hard for sandstorm to grow is the requirement that apps have to specifically be modified to work on the platform, and it never reached critical mass of developers building in sandstorm support to their apps. So it's essentially a chicken-and-egg problem. I'm not sure what the solution to that is.

I would love to read a pseudo-postmortem (I refuse to believe this heralds the death of sandstorm) by @kentonv about what he thinks the main challenges of getting to a truly decentralized world are, how sandstorm plays in, and where we go from here.
The concept of cache misses and the importance of cache locality is nothing new. That's HPC 101.

Demonstrating that in the real world a specific data structure performs far better than the theoretically optimal data structure is not. That's novel, unless you can find any prior work that presents the exact same findings.

That's one of the main problems with ivory tower types: claiming that a novel poem is nothing new because all the words in it were already known and even published in a few dictionaries.
Js can and does get compiled incrementally if people do it correctly. It's fully supported by blaze. It's just that a bunch of old codebases globbed everything, so it appeared no incremental.
It's complicated but the gist of it is that they are trying to commercialize it, yes. For what it is worth, you might be able to find it in commercial software once they were successful with their business endeavors.

2. Yes and there are two mechanism for handling seams. First, the inpainting which extends the point cloud and can provide a higher sample rate. Second, a postprocessing step that heuristically fills in any seams that may still be present despite inpainting.

4. The downside of it is that one needs a lot of resources in order to try all of these variants, which not everyone is lucky enough to have access to.
You seem to have made an assumption that the mainframe is “legacy hardware”, on a thread about the latest generation of mainframe hardware... As long as IBM keeps building mainframes the business case for anything else will remain unattractive. Unless you have some information to the contrary, it doesn’t make a lot of sense to invest (financially or technically) in switching.
I feel like they got heavy inspiration from unity. There is a lot of terms and functions named exactly like and perform the exact same functionality in unity. And having programmed in both unity and unreal I can say they aren't just generic naming conventions. But I've only briefly read some documentation so they might actually say it was directly inspired by unity. At any rate great job huge undertaking. I'll check it out some more.
I don't know, I'm just questioning the quality and magnitude of the signal sent by voting for a third party.

The public memory is so short and so malleable, people forget things week over week let alone the entirety of an election cycle.

The issue with third party voting is a classic case of the problem of coordinated collective action.

Would-be voters don't participate out of perceived futility or participate in the dual party system for similar reasons.

I don't know how to solve it but there does seem to be growing agitation in the electorate with the current system as it stands, with the Electoral College under public scrutiny and with media support. To me that is a signal that times are changing.

I don't print much. I bought an HP printer with Instant Ink strictly for the free tier (10 free pages p/m). This privacy issues concern me.

That aside, I've been thinking about what is the minimum amount data needed to identify what's being printed. For example, if you knew tbe lenght of the first X words, how many words would be necessary to identify a source? If you added the awareness of periods, how many words?

Long to short, it seems to me, simple and basic meta data used wisely could be used as a fingerprint (or sorts) to identify what's being printed without actually needing to capture the actual content.

Once upon a time, Jon Bentley wrote one of his Programming Pearls (IIRC) about two string reversal algorithms; both were Big-O identical, but one finished in seconds on a sufficiently large string and he killed the other after several minutes. The punchline was that the second was exactly pessimal with regard to paged VM.

This wasn't a new realization, even in 2010.

The neat thing is that Bentley's string could probably be reversed in cache today.

> Yeah, an incidentally-optimal-with-a-certain-architecture algorithm is great as long as you can count on the architecture remaining constant.

Choosing an algorithm based on the architecture it will run and the data sets it will operate on on is the right thing to do, period. That's engineering.

If you have a different architecture, you choose a different algorithm. You don't go looking for some mutant yeti super-algorithm that somehow runs well on all of them. This is just a symptom of computer science's obsession with generalization, which is rather counter-productive.

> Of course, a lot of algorithms are going to GPUs and how these structures relate to GPU processing is another thing I'd be curious about.

GPUs are a good example for how you need to craft an algorithm to fit the architecture, not the other way around. The way you can program GPUs today is different from five and ten years ago.

What? I've never had any issues with my HP laser printer in Linux.

I can attest that in Windows 10 I always have to delete and re-add the network printer whenever I want to print something because apparently being offline even once is enough of an upset to send the Windows printing system into paroxysms of fear, where it will tremble mightily, unable to re-try in less than 20 minutes. Don't get me started on how it's impossible to share a cellular connection over Ethernet because plugging Ethernet in turns the cell connection off to "save power" either. That little turd of a feature cost me a couple hours last week.

> The math works fine. What doesn't work is the productivity distribution from work done.

I don’t think you really appreciate the scale of the numbers involved. It’s hard to find good numbers for Singapore, but by 2060 the US will have 186 million workers and 95 million retirees. Let’s apply those ratios to today’s economy. That’d be about 80 million retirees. If you took the entire income of the top 1%, that works out to $25,000 per retiree. The maximum social security benefit works out to $45,000. Then the average Medicare spending per retiree is $16,000 per year. (And don’t forget, that 1%-er money is also earmarked to pay for universal healthcare and free education.)

I have the HL-L2360D and it's been great. I love the IPP Everywhere drivers and don't have to worry about anything in particular anymore.

After this I would only get a printer which has IPP Everywhere or at least is supported by foomatic-db. hplip can get lost.

I can also get non Brother branded cartridges as they don't make a habit out of selling the printer so cheap that they have to then rape you on the price of the cartridges when it's time to refill.

The non-Brother branded cartridges work just as well as the official ones and I can go into any major office chain and buy them off the shelf.
The specific proposal, price-gating of access to notable tourist landmarks, directly and out of no fundamental necessity simply creates yet another wealth-based inequality.

Poul-Henning Kamp is rather famous for writing code that uses mmap and a straightforward data structure for giant blobs of data and arguing that the kernel memory manager should handle the details. To my knowledge, most people dealing with data larger than memory use more active techniques.
> It’s inexplicable to me why able-bodied people

That's the problem. Very few people can still work at that age. To be more specific, there are more or less two types of labor: physical and mental (cognitive).

Very few people can do 40 hours of physical labor when they get to be 65 years old. If they've been working physical labor, their body is beaten and used for the years of abuse. They literally are no longer physically capable, not to mention the significant pain they're in from working a life of physical labor. If they've not worked a life of physical labor, then very few have the physical ability to start doing so when they're 65. Yes, if they've been fortunate enough to have top-notch medical care, good exercise habits, good genetics, and good luck, they may be able to do physical labor for 5-10 years, and then what? Also, a failure of any of those 4 can destroy you suitability for labor. Also, if they've had good medical care and the privilege to maintain a rigorous exercise regime, they likely have enough money for retirement.

In terms of mental labor, first of all, what percentage of the population is capable of skilled cognitive labor, like programming? Also, even among the minority of the population that is suited for such work, some people start losing a significant amount of mental acuity by they time they're 65-70.

In short, any society that fails to care for its elderly has failed, period. Yes, these folks have no choice but to try to get by as best they can, but it's a societal failure.

Surprised that any reasonable person would disagree.

Brother makes printers here with giant refillable ink tanks, instead of cartridges. Still on the ink that came with the printer when I bought it almost two years ago. On HP I would've had to replace the cartridge every few months for the same usage.
Such automation doesn’t exist now and may or may not exist in the future. Moreover, the kind of jobs necessary to take care of a larger elderly population (doctors, nursing, housework) will be the last to be automated, if it’s ever automated.

Except for people trying to be fit, your speeds keeps increasing for a while. When I was in good bike shape (am not now), I would need to ride 20 MPH to get a decent workout. Riding 15mph wouldn’t even get my heart rate to 120. High heart rate is important to get the health effects of a workout. The whole reason I commuted on bike was to get a workout as I travel

Either

A) the paths need to be safe up to a reasonable workout speed (25 mph)

Or

B) people wanting a workout need to buy heavier and heavier bikes to go slower. I can get a great workout at 15 MpH if I ride a 49 pound fat bike with huge knobs.

It would seem pretty silly for me to commute to work at 15 mph, get no health benefit, then go spin on a stationary bike at 25 mph.....
I alway felt that Sandstorm would be an ideal project for one of the NAS vendors like Synology, QNAP, or Netgear to get behind.

The problem is that the most used memory model for algorithms performance research is not true in the real world: O(1) memory access. In the real world memory access is not a O(1) operation, it takes a different amount of time to access memory in the different levels of cache.

It's interesting that email isn't more common in promotion of OSS. It seems like there's lack of tooling and so people put it in the "too much work" bucket. Email is one of the most successful marketing channels across all industries and so it's a shame there's nothing out there for open source makers to help them easily add email to their toolbelt.

I remember many such things said about TV also. Many of the complaints sound similar in my head. Including things like 'using psychologists to make more addictive TV', or 'subliminal messaging in advertising' will hypnotise you buy shit.

Basically apply the best practices that you had 25 years ago for TV (not too much, make sure it's not too much for their age, etc) and you'll probably be fine too.
It's hard to overstate the importance of adult content to progress in networking, specifically.

Hm, how would I look into that? Does it have a log you could share with me? And is anyone else getting this kind of warning?
It’s a matter of priorities, isn’t it? Like someone else said, if you take a certain amount of other luxuries (you might consider retirement one of those, I guess) out of the equation, I’m sure the math would work out. As long as everyone has access to basic necessities. Of course, if the population is dying out, no system will last forever anyhow.

I also suppose it depends on how you define able-bodied. Sure, some people are technically able to perform work in their old age. How many can do it and still continue to feel alright, rather than suffer from aches and fatigue that seriously hamper their quality of life in their final years?

When I was a kid I read the essay ”In Praise of Idleness” by Bertrand Russel, and it left an impression on me. I don’t think we need constant growth and increasing material wealth at any cost. One of the things I’d rather see instead is that people who’ve led a long life can retire and finally take it easy for a few years before they pass.

Right. He mentions a few but they again seem to be things chemists were aware of. I really wanted to see the patterns chemists didn't think of instead of the algorithms recovering what was already known.
They are rightly saying that DoH will secure requests from tampering --- but when it's the owner who's doing the tampering, it becomes yet another anti-user security feature.
