Not to be a Linux apologist, but you have to do the same with Windows anyways, no? (Keep in mind it's been almost a decade since Windows was my daily driver)

For example video drivers you always have to install separately, and I remember having to copy drivers for Ethernet cards after formatting.

I'm currently making a game engine myself and it has been both challenging and fulfilling.

I don't expect people to use what I've made, but as long as I learn from it, it is not going to be a waste of time.

Each step on making the engine has been full of important lessons:

* With OpenGL I learned about graphics and how they are rendered on a screen. Knowledge on this has helped with optimizations on my other projects made with Unity

* Adding Lisp scripting has renewed my love of Lisp and has made me realize the importance of scripting on game engines

* Implementing cross platform has made me realize just how difficult this is and why most people jsut go with Unity because it's offered out of the box.

* Designing APIs and functions is not trivial. Each game engine has a different way of doing things and it is mostly dictated by their technology stack.

I'm working on this mostly for learning purposes and I've been logging my journey every step of the way. If anyone is intetested in checking it out, or give suggestions or critiques, here's the link:

>this addresses a fundamentally different issue. The article concerns outflow of capital surplus from the developing world to the developed world.

The report is about the total flow of money, the article just highlights capital flow. Why is this a different issue than the "extraction of resources?"
Well, it's not an easy suggestion, but certainly an interesting one. I'm going to think more about this one. Thanks for providing a new thought on a hard problem!
$10k/month might sound like a lot of money (and for a lot of people, it genuinely is), but it still takes a _long_ time to become a millionaire at that rate. 100 months or ~8 years if you save every single cent you earn. Pay tax on it and you're up to 11 or 12 years. Pay rent/bills/groceries and you've probably doubled that again to 20-25 years, even if you're super diligent saving and live very frugally (maybe significantly less than doubled if you like somewhere very inexpensive, but it'll still be more than 12 years.)

So you're arguing that even though Japan's contact tracing is missing ~80% of the cases, it's still catching the ~20% that would have spread the disease disproportionately? What's the difference between the high-spreading groups that they catch and the low-spreading they don't need to? Is this a characteristic of the patient's biology, behavior, environment, something else?

Maybe you're saying that R < 1 almost everywhere in Japan, and they're disproportionately identifying the few places where it's > 1 ("circumstances where things can grow out of control") and intervening? I could believe that; but that still fails to explain why R > 1 there only in a few hotspots, while NYC ended up with ~20% infected even after lockdowns.
Also notable in the context of "two-way mapping" is Dynamic Windows, the Symbolics Lisp-machine window system. Dynamic Windows was a "presentation-based interface", by which its authors meant that data structures had "presentations", which were interactive widgets that could be used to interact with values.

For example, if you evaluated a Lisp form in the Listener, it printed out the value just as you would expect, but what you might not expect is that both the evaluated form and the returned result would automatically be mouse sensitive and would offer menus of operations to be performed on them that were relevant to the data structures that they represented. The text on the screen wasn't just text; it was a "presentation"--in other words, a kind of reference to the in-memory data with an interactive visual representation.

Later, Apple did something similar with SK8, a sort of Hypercard-on-steroids built on Macintosh Common Lisp. Its design was not exactly like Dynamic Windows, but it shared the idea that values could have presentations. A distinctive feature of SK8 was that you could grab and drag widgets with the mouse, then drop them into a listener window to get references to them that you could then use in code to operate on the live widgets.

So there's definitely a good amount of stuff you can do in this "two-way mapping" direction. Some of it has been done before. Doubtless much more remains to be discovered; it just needs the application of labor and imagination.
This was also strange to me. I'm used to people bringing home made food with them to the office, then heating it up at lunch time and eating it. But I cannot imagine being sent a freshly cooked meal in the afternoon. Mind-blowing.
This is a great introduction to discrete math. I found it valuable for deciding what topics to invest more study into. Good survey of discrete math.

I'm about 70% through this book. I've done every exercise and have meticulously journaled about each concept as I encounter them into my Zettelkasten.

Best part: you can read it online and then determine if you want the physical book (which I prefer for math).
Couchsurfing was fantastic in its early days, then came the era of using websites for just-a-little-bit-too-much-dating, then they went .com and tried to be "cool" with redesigns, eventually drowning the simplicity of their concept a little bit too much.
That $25 yearly fee slapped onto everything, with no chance to even connect with previous contacts, is disappointing to say the least.
No doubt that the meaning of "couchsurfing" will far outlast the website, especially now.

This article is completely wrong. Slashdot, Digg and Reddit were already at 100% of full-power way before Google Reader ever shut down. And him citing that the causes are unknown is so completely naive. It's obvious. And it was obvious at the time to many who used RSS in 2012. Google is in the ad business, and RSS doesn't do adds. Not really, and not then. They realized they were competing with themselves and closed it; it's that simple. God, I feel like I got baited to reading that post because there was no new or insightful information whatsoever other than the title line. We should bring back RSS, and make the web more about conversations and communicating, than listicles and click-bait. 5-10MB of Javascript per page load, 1px tracking images, endless stupid ads, and now every single site that I go to has a pop-over that I should sign up for something, which gets in the way of the content that I am only going to spend 30 seconds reading anyway and then never return to that site ever again. The web has very quickly become a cesspool of non-information. It's like a bad shopping mall.
Thanks for assuming that it's an "off-the-cuff opinion", as opposed to what might have been gathered from a great deal of expert reading. I was trying to be polite -- unlike yourself, sadly.

I'll second that. Theft seems to happen as a matter of course in hostels, with just about everyone I know who uses them regularly having an experience. I don't hear too many bad CS stories except the friend of a friend who had to stay with a nudist (i.e. urban myth. The nudists on CS seem to be very open about it.)
Sounds like that runs afoul of GDPR.

The exams are designed with algebraic solvers in mind and typically, you don't actually find derivatives and integrals. Instead, they'll show you a graph or table instead of the equation itself. Typically students are allowed to use a TI N-spire CAS CX on their exams, which has a lot of the same capabilities as WolframAlpha.
What difference is it if the state or the company makes the decision? In either case, it's "come in and risk exposure, or lose your unemployment benefits."

> Have you seen somewhere claim that MADV_FREE allows avoiding a shootdown?

I haven't, and after looking at mm/madvise.c [ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin... ] I guess it doesn't. Also, the unmapping happens immediately.

MADV_DONTNEED doesn't help either, it also seems to invalidate immediately.

That only leaves MADV_REMOVE, which AFAIK doesn't work on anonymous mappings...

Builders of Oldest Known Temple Had a Surprising Understanding of Geometry
2017 through early 2018. I think (and hope) that they've changed the process.
Like the article says and as applies to almost all failed startups / products, it can all be traced back to bad management.

I've been a heavy CS user for over a decade, I've been to events at their (now defunct I suppose) office in SF, I met their CEO at the time (one of many) and even did a walk around the block chatting strategy with their VP of Product at the time.

After building lifelong relationships through the platform, and comparing my experience as a user with management's side of the story, it was clear to me that they had very little understanding of their userbase.

Couchsurfers are broke. By definition. Meeting people is a huge value add, and the longer you stay on the platform, the more you gravitate toward the "community spirit" and less "saving money" side of things. But you are kidding yourself if you think that first time CS users are on the platform for any other reason than squeezing a few more days out of a thin backpacking budget.

Not only are they broke, but even the community often has an anti-money ethos. Just look at the outrage (as the article points out) when they switched to a B corporation. And it makes sense -- taking an inherently capitalist product (lodging) and building a community to make it free creates a very specific narrative.

Therefore, the expectation that CS users, especially first-time, will pay even a dollar on the service is DOA. They need to make money (exactly how much is up for debate), but this isn't the way to do it.

But that doesn't mean there aren't any other choices! CS Event sponsorships, cross-product integration (language learning, travel deals FFS), other corporate sponsorships, a more Airbnb-like private experience (maybe the community would hate that too, who knows), partnerships with local tourism authorities, discounted tour / event packages... None of these were even close to tried.

I'm not at all advocating that Couchsurfing should have become Tripadvisor, but to barely even consider a few alternatives to nickel and diming a bunch of broke backpackers just shows that CS was on its way out long before COVID-19...
Certainly true! I hope those places get what they need soon. But if Alameda County can safely start reopening before them, I don't see any value in waiting.
Sure, just look around, do you see any successful micropayments processing companies? Do you use any of them? If any of them were successful, you wouldn't be asking this question.

There was a wave of micropayments startups about 6 years ago. The only one I remember is Flattr. The crypto bubble came and gave new hope because maybe the reason micropayments failed before was the credit card processing fees. Nope, still didn't work. I don't use Brave Rewards and have never heard of anyone making more than pennies with it.

Xanadu was one of the original visions of the internet from the 1960s. It sounded like a lot of the idealistic plans people come up with for micropayments where content creators can collect micropayments from viewers. Of course it didn't work.

Micropayments is an absolute cemetery of a business model.
> I'm guessing what you mean is for the TLB to get a notification when the physical memory that contains the page mapping it was loaded from is changed.

Yes, that's right.

Let us conceive of an inclusive cache architecture, just for the sake of argument. L2 already maintains a directory listing of all the lines which are present in L1I and L1D, and forwards cache coherency traffic to those caches based on the messages it receives. Expanding this to the ITLB and DTLB would be exactly the same circuits. The hard parts are already done.

But I think you're onto something with the hardware-managed dirty bit. Its much less general than the S->E->M transition, and doesn't need the Exclusive state at all.

I've done a bit more digging in the background. Turns out that ARMv8's TLB invalidate instructions are broadcasted operations. You don't need IPIs to execute them on every core. So processors do have some snoopy and/or directory management hardware interface for managing TLB shootdown. It just isn't as general-purpose as the rest of the cache maintenance hardware.

Yes, "allows." Copyright lasting as long as it does today is not a natural state of the world; it's a decision that was made by people. If we had the copyright laws today that we had at the founding of the United States, all of these photos would have long since entered the public domain. If we had the copyright laws that we had until 1976, most of them would be.

Many people, myself included, don't believe that copyright should last nearly as long as it does today.

Now, not that this has much to do with the physical collection, of course; physical property is different. But if you can obtain a copy of one of these photos, in my opinion at this point you should be able to do what you want with it.
The first clue is a text editor that uses 180mb of ram :)
It's quite simple to use the web view process for nothing but the actual UI, and to move any intensive logic to a separate process (or even native code). It's also very possible to make that UI code quite performant (this takes more work, but VSCode has shown that it's possible).
> Entire patterns of thought become antiquated as our communication wiring adapts to the ever increasing pace of society. Social media is driving dopamine hits from shorter and shorter forms of engagement.

I think you are extrapolating a little too much from your personal experience. An obvious counterexample to our society trending to "shorter and shorter forms of engagement" is the rise of long-form podcasts and long-form independent reporting.

Plenty of people still enjoy literature and the way in which it can convey ideas that non-fiction does not. My impression is that you'd have the same reaction to more recent fiction by, say, Cormac McCarthy or David Foster Wallace. I'm not sure Harry Potter is exactly a fair comparison of a work that aims for the same register as Moby Dick. As far as I know, 19th century literature with a simpler prose style (for example Sherlock Holmes or Poe's short stories) is still entirely accessible to someone with basic reading comprehension.
That's OK, lots of people fail to RTFA, but I really like reading about this stuff.

> Green-threading has become a good idea again because we now have a kernel API that is used to multiplex a lot (but not all) I/O systemcalls.

OK, that makes a lot of sense. I had to read up about how epoll is different from select/poll (that's how long it's been since I worked in C :). Clearly epoll was needed to make green threads efficient, but from what I can see, by the time epoll and friends were widespread, the pthread model was entrenched in Java.
Ah, okay, it was late 2018 when I interviewed there. I guess they got rid of it since.

Sometimes all you really need are simple CRUD operations against a data store for a particular app. Most ORM fill that roll quite well in my opinion. They are also great for rapid prototyping. I think where people run into problems is trying to shoehorn every data operation through the ORM layer, especially for more complicated data storage requirements. That being said, working with knex was a miserable experience.
what I can't understand is that I never heard of this covve app neither most of the affected users in the comment section on reddit or troy website or even here as no one thought of it , and my email does exist on the breach, also the data seem to be huge (103,150,616 rows/90GB)for an app that have about 100k install, need some explanations here.
Sure, except that there is an objective standard for total value with improvements (the sale price) and there is no such standard for the "unimproved" value of the property. No one is going to tear down any existing improvements and leave the land untouched to revert back to nature for a century or so before putting it up for auction. The dividing line between "improved" and "unimproved" value is arbitrary, and biased against the property owner.

What LVT proponents really want is some kind of oracle that will tell them just how much of the (estimated) market value of a property is due to the direct efforts of the past and present owners of the property and how much is external benefit from the actions of others. Two problems with this approach are (a) there is no such oracle and (b) the "unimproved" value includes external benefits property owners provide to their communities which are not included in the assessed value of any obvious material improvements to their own properties. There is something fundamentally self-defeating in any proposal which would result in taxing people extra for their contributions to the public good.

The idea that land has any "unimproved value" to be taxed is flawed from the start. In fact land has no economic value until someone claims it and puts it to use. If you walled off a piece of land such that no one could reach it, even an otherwise choice parcel in the middle of Manhattan, it might as well not exist. All economic value is the result of human improvements, though they don't always take the form of physical changes to the property. LVT takes physical improvement as a proxy for improvements attributable to the property owner(s), but this is at best a lower bound and significantly understates the owners' own contributions to the property value.
Hacker News is smaller than most major subreddits in terms of usage. 400 upvotes is considered a lot here. The site is extremely simple and something that could be replicated in a couple of days at most by most engineers. It doesn't process money or really require a lot of content moderation either.
In Mumbai, the person working is likely to leave early (say before 7am). The person cooking (typically mom or spouse) gets to lunch later, around 10:30 and it gets delivered. Most Indian food is not great when eaten cold. This also avoids needing to buy and store vegetables since you can get to the market in the morning and buy what you need for the day.

It makes life easier for all concerned.
