> If so, even if you don't include gender as a feature itself, your outputs may end up being biased (in the technical sense) by gender.

Part of the problem is people using the same word to mean multiple things. For instance, "bias" has a precise mathematical definition in the context of statistics: https://en.wikipedia.org/wiki/Bias_(statistics) . And this sentence makes no sense with that definition. In fact, with linear models it is mathematically impossible to make a "worse" model (in terms of mean squared error) by including more variables (like gender, age, race, etc...).

> you can't be "blind" to race, color, religion, and gender

Also I am not sure that this train of thought actually leads to where we want to go. A perfect model isn't necessarily blind to these features, a perfect model treats everyone as an individual.
The issue is how the process is perceived by the user. The average user is not going to understand why a new app has to be installed/purchased. It is perceived by mass as a bit scammy. Personally, I would rather pay a yearly subscription similiar to adobe than to have to repurchase every new update.
tl;dr - get X86 hardware, not ARM.

Most ARM boards have lacking software support and run vendor supplied patched distributions or kernels that are out of date (or at least will be after a short period of lagging updates).

If you wanted to run a robust and patched up ARM Linux distribution for networked use, you usually want timely security patches, and this requirement narrows down the options a lot.

Even the best board-specific distros (like Raspbian) lag in the security updates dept so for many uses you want to look at which boards are officially supported by mainstream distros.
Poor people can't afford meat around the planet. Meat should not be accessible to most Americans.
The Windows Update system is engineered so that individual updates can be selected/deselected without affecting the ability to install other updates. The slowness of Windows Update, as I understand, is related to this fact.

However, that being said, Windows Update for me as a user that would apply all updates anyway, was unbearably slow, and a big part of the reason that I switched to Linux and FreeBSD years ago and never looked back.

I guess for enterprises that want to deselect certain updates for various reasons relating to their setup, Windows Update is probably a great selling point.

I still don’t get why it has to be so slow for the default case where all updates are applied though.
What makes you think that we squander that potential? If anything, we seem to try to extract as much potential out of people as possible, given sky-high college attendance rates and that we aren't really getting much out of it, given that most of that education is really just used for signalling.

I personally don't see any evidence that we could get that much more out of the population and I think we even overemphasize education, leading to debt and underemployment.

> non uniform distribution

Is it really imperative to treat reality as if it was uniformly distributed? Why would you want to cast a non-linear environment into a linear shape? Are we trying to get rid of non-uniformity (which is realistically impossible, let's be honest) or are we just correcting towards the falsehoods of current thinking?

Microsoft could have a flawed development process but the slowness of the update procedure and how it seizes control of the machine is much worse in terms of UX. My Ubuntu laptop gets updates almost every day. I could make them happen in background but I want to know what's going on so I make it display the list in a window, check it and click OK. From now on it takes little time to finish, even if there are new versions of the kernel. I recently updated a Windows Server 2016 VM switched off since September and it was a half day long nightmare of downloading / updating / rebooting loops. If I ever considered to move back to Windows (I never did) that would have made me change my mind. Anything but Windows.
I'm really happy with an HP MicroServer, it does have a fan but is using a low power CPU so doesn't run hot. None of the cheap ARM systems can take ECC RAM.
Why, necessarily, must human value be remitted by a central authority and its inherent fickleness? Or, more importantly, why does belief in predetermined value, cause a belief that the State should suddenly take charge of measuring value and doling out its consequences?

Mental and physical abilities seem useful insofar as they produce things of economic value. Different people, today, already, have different and diverse abilities to produce economic value; and as a result they come to possess diverse quantities of wealth. How does believing that people's potential wealth is predetermined, change things?
What I don’t understand is why can’t they just simply replace the binaries and reboot. I am sure 99.9% of pc owner must not apply hotfixes or updates selectively. They could make those fast, and keep the slow process for the 0.1% who need this level of engineering.

If this is the case, I'd suggest you get an appliance instead.

Not "free work" either. As payment for your membership, a work trade in return for the benefits of membership.

Consumer cooperatives (which are actually legally _owned_ by their members, via member shares in the coop corporation) have been doing this forever. Like the famous (both loved and hated) Park Slope Food Coop [grocery store]. The Park Slope Coop simply calls it a "work requirement", and it is "2 hours and 45 minutes once every four weeks."

The Park Slop coop is famous for crazy internal politics, so a work requirement is definitely no magic bullet against such. The Park Slope Coop is also loved by many though.

You're probably being downvoted since your comments appear to have nothing to do with the article or any ongoing discussion in the comments section. The use case the authors had was deduplication/change detection of large art asset files. Just how are reversible hash functions for small fixed size inputs relevant to that?
16 bytes per cycle is what they quote. Imo, that's pretty impressive.

For comparison, xxhash is the closest thing to this that I'm aware of and clocks in at around 1.7 bytes per cycle using the official implementation.
Brave New World. I'm telling you,....
I can provide ALL the proof you need on my Asus STRIX 1070. I run everything at 2560x1600 synced to 60fps on my 30" monitor with Ultra settings. Those benchmarks are all enabling AA, which is just wasteful and not required at such resolutions. So yes, with AA, below the 60fps target. But right now my library of 418 Steam games, all run rock solid at those framerates. Metro, Batman, BF1/4/5, Witcher, Alien Isolation, Fallout, GTA, Bioshocks, whatever I throw at it.

Though the point of this discussion was the CPU not being critical anymore. If you need more FPS, buy a more expensive video card, not a CPU.
>Rather than launching into an uninformed rant about bureaucracy, you should read the background to the Ghost Ship fire.

Did you just want to restrict this to the Ghost Ship fire? I only used the quote as a starting point, I don''t intend to talk about the Ghost Ship fire and its particular circumstances.

I'm talking about the creeping codes and bureaucracy in general, and I've already said that inspection is OK. Just not the piling of risks and litigation to the people running the place for every little thing (that goes beyond fire hazard etc, to stupid stuff like someone slipping on the wet floor and suing).

>Ridiculous — those adults aren't in a position to evaluate the risk

They wouldn't have to evaluate any of those things if the place had been properly inspected (as I say in my comment).

If it's "not inspected in years", it's the state that should be put to blame, not the owners.

No, it's an actual answer of one way that a number of relatively small and some fairly large coffee shop chains can and do survive when Starbucks exists and is ubiquitous.

It includes, of course, an endorsement of the taste to which those shops appeal as part of that strategy.

Physcial qubits currently suffer from noise problems and so logical qubits have to be simulated. You can't just implement them directly in a scalable way in hardware. So, you could say that a meaningful, scalable quantum computer of any kind has not yet been built. You can certainly say that a quantum computer capable of breaking real world encryption is very far from current reality.

I also think Rust's mio is sufficiently behind-the-scenes that the only people who will encounter it will already be well aware of its purpose; typical Rust users will be two levels removed from mio, if they're using it at all.

Weed (THC) is illegal in the Czech Republic, thus it is not openly advertised. Search for a "weed bar prague" in ordinary google search; various forums and reviews will show up. Then put some bar name into google maps and there will probably be a "user guide" in reviews. If not, then move to the next one - there are dozens, if not hundreds. If there is no guide and you're certain the bar sells weed, simply ask for it directly, usually the only requirement is to buy a drink first.
I think the 920 was fine, but the Xeon granted two more cores, and higher overclocking frequency for me, plus it was only $90. So more future proofing, as games take more advantage of multithreading. Increasing your RAM definitely should be on the list though.
As someone who teaches layout online (Contextual Electronics) it really comes down to how much time you want to spend and how willing you are to deal with mistakes. Electronics is a complex field and the only way to "recompile" a project in electronics is to spin another board. This is usually a tough transition for people coming from software, which is many of my students.

That all said, PCBs have never been cheaper or faster and I think a lot of the software has gotten very good. I teach with the open source CAD software KiCad, which has improved a TON.

As for finding people to do the design, usually my layout jobs come via referrals. You can use a site like Upwork, but that is usually a race to the bottom costwise. Quality doesn't necessarily follow that curve but I usually err on the side of hiring experienced folks when I bid out jobs as the overall hours spent will usually be lower, even if it's at a higher rate.

Other things to think about is who will do the assembly, the target cost of the boards and what functions you want to include. Usually taking an iterative approach where you start with a pluggable ESP32 Dev board and then have it plug into a simpler daughter board is a good start and lower risk overall.

> because the faster hash (every operation) outweighs the extra full string checks (rare)

I'm confused... don't you have to do at least one full string check for every table lookup on a hash table, to ensure the value you're returning is really the right key, and not just some other key that happens to collide?

In other words, if I have 32 buckets in my table and one value stored at table["hello"], and table["goodbye"] happens to hash to the same bucket, how do you know whether to return not-found for "goodbye" without a full string comparison? (Or for that matter, how do you know whether to return the stored value for "hello" without a comparison?)

I wish people used mmap less.

Creating a new memory mapping can be pretty expensive! On both Windows and Linux, it involves taking a process-wide reader-writer lock in exclusive mode (meaning you get to sit and wait behind page faults), doing a bunch of VMA tree manipulation work, doing various kinds of bookkeeping (hello, rmap!) and then, after you return to userspace, entering the kernel again in response to VM faults just to fill in a few pages by doing, inside the kernel, what amounts to a read (2) anyway!

Sure, if you use mmap, you get to look at the page cache pages directly instead of copying from them into some application-provided buffer, but most of the time, it's not worth the cost.

There are exceptions of course, but you should always default to conventional reads.

I am not an expert on this subject matter but I suspect much of the required structure for younger kids is only a necessity due to constant restrictions and monitoring that's been put in place by modern society. In other words, we are not giving enough space to develop on their own terms and explore their surroundings.

I grew up in the 80s and 90s and remember spending a lot of time unsupervised going about wherever and doing all sorts of wild things well before I was 7 years old. Looking back now as a parent it is absolutely terrifying to me what I was "allowed" to do. Then again when I think about the Norma in countries like Japan (where it is not uncommon to see kindergarten kids walking home by themselves and crossing streets and intersections), I am reminded that kids can develop independently to a great tune than we give them credit for. I don't know about Japanese kids materials levels but I've noticed that they are typically given more freedoms to act independently and spend a lot more time on outdoor and social activities. If I had to guess I'd say they are a lot less materialistic than their Western counterparts.

As for my own child, I try to let him be independent even at 1 year. For example, we have a TV stand that any parent would be terrified if their kid climbed on it. I was terrified at first but then with some observation and secret supervision I let him climb it. To my surprise he quickly learned how to turn around and get down safely. There was only a single time when he fell from it sideways unhurt, but now he goes up and down like a pro without any supervision. I can leave the room knowing he will always get down fine. To what effect independence will have an impact on materialism remains to be seen but I suspect one of the commenters is right on the money with mirroring behavior and values.
As a user, I genuinely don't care about your aesthetic when it comes to your IAPs. I want a clear-as-day notice well in advance that you're asking to take real money for non-physical goods and/or services. If some group is working to make that clearer, I'm in favor.
I was recently cleaning off someone's Mac and made this note:

> I found no fewer than eight fake Adobe Flash updaters, six of them identical and signed by Nevaeh Mitchell (WMAA75SZMS), one signed by Lambert Jeremy (B4MCPEJ42J), and one by Wolfe Bailey (3W8NF7PWUL). It does not appear that Apple has revoked any of these signing certificates or flagged any of these installers through macOS's built-in malware removal tools.

So it doesn't seem to me that malware authors are exactly afraid of signing requirements.

I am intrigued by this as well. I think they check for the existence of certain primitives and a sequence in which they are drawn. For example for level 1.1 where you need the 60 degree angle, if you use Explorer mode to view the solution and then you draw a "cheated" line on top of it, it won't give you a completed level because you don't have the sequence (2 circles and an intersection point). It also doesn't allow you to draw another line on top of an existing line, so you'd have to restart the level in this case.

It wasn't when Starbucks started. There used to be a real dearth of quality prepared coffee in America, and Starbucks was often the first place in many towns (not talking NYC or LA or San Fran or Chicago) to get a decent cup of coffee.

I don't know what to take from that though with regard to what y'all are arguing about, I can't really explain the economics of it all. But I think it's a fact that at the point Starbucks was expanding to be national, it was not true that most places it was expanding to had plenty of places where you could get a much better cup of coffee at a comparable price. Starbucks actually brought "coffee culture" to most of the U.S. (if it wasn't them it would have been someone else, this was when "foodie" culture in general was becoming a thing, people with enough money to were becoming more interested in 'gourmet' everything).
This is definitely unfortunate, but in my defense I was not aware of Rust's mio (or anything related to Rust beyond its existence) at the time of writing and naming my library. I have no emotional investment in the name, so I'm open to suggestions should anyone take issue with it.
