It’s a weird feature of humanity. Once an idea (or meme in the original Dawkins sense) starts spreading, it’s very hard to make it disappear, no matter how ridiculous it is. See flat earth theories, various nutty religious theories (“Jesus crossed the ocean and lived the rest of his days in the USA”), etc.

I guess it’s a social thing? Humans have a fundamental need to bond and feel part of a bigger “us” and these things serve as a substrate for it.
Because saying "blacks" is politically incorrect while saying "whites" is just fine. Which interestingly just goes further to exemplify this state of "politically correctness gone extreme" which the author is warning us about.
Cannabis ain't illegal where I live. Come visit and we'll get blazed
That seems open to abuse - wander around London until you get pinged with a false positive (vary your appearance - hat/glasses/beard - to make it more likely), then go and commit your crime, knowing one of the major tools is neutralised. Either it's good enough for general use, and we don't need this (_maybe_ have an exception for people who have been hassled multiple times), or it shouldn't be used.
It’s the same internet, just like when we switched from dialup to broadband.
The analysis that Intel’s lower peak throughput makes the iPhone 30% less efficient with spectrum stands on very shaky grounds. The effect needs to be coupled with the probability that 1gb rate is actually allocatable to a phone: which requires exceedingly favorable conditions and is therefore rare in common usage. Secondly even when peak rate is available but not utilized the impact to spectrum efficiency tends to be minimal as the unused capacity can be allocated to other users (a complete analysis is complicated as it depends on the figure of merit that carriers use). There’s no way carriers would even accept a 10% reduction in bandwidth efficiency, even from Apple.
Following up a bit for context and using Petsmart as an example, in 5.5-6oz cans there's a store brand at $0.46, Friskies at $0.56, the gourmet version of the store brand at $0.56, Simply Nourish and Authority (another store brand) at $0.89, Evolve at $0.95, some Simply Nourish grain-free options at $0.95 (which likely contain the pea protein that's part of the article's coverage), then you're headed up towards the $1.20 and higher range for the larger cans. Notable at $1.25-1.29 is Science Diet.

If you're looking at the 3oz cans instead, they start around the same $0.45-0.55 range then migrate upwards quickly, so you're typically paying the same as Science Diet for anything except the cheapest of wet foods. At both sizes there are plenty of options that move up into the $2+ range.

It's remarkable to think about the profit margin there has to be on these, particularly when you look at the ingredient lists and find all the "meat by-products," "chicken by-products," "turkey by-products," "fish meal" and the like. For the price per pound of this stuff I might as well be buying them fresh fish, boneless/skinless chicken and the occasional New York strip steak or even a nice filet.
How should this be contrasted with Tiananmen Square? Was that a “shift” towards a more capitalist system?
Hopefully that professor didn’t teach anything close to electronics/physics/chemistry.
Exactly, this is the definition of Newspeak in Orwell's book.
I just moved back home to New Orleans after twenty-something years in various other corners of the US, and seeing the aisle of local products is both disorienting and familiar. There’s a few brands with pro-looking graphic design, a few of which have made it out of the state (you can buy Zararain’s stuff elsewhere, for instance), and a lot of brands you’ve never heard of outside Louisiana with labels that look designed by the owner’s cousin who has the Adobe suite.

The stuff with the amateurish labels is inevitably the best. It’s not packed with preservatives and stretchers and all the other crap you have to adulterate your food with to be able to ship it across the country and have it be shelf-stable.

There’s other surprises around the grocery store, but the feeling’s most intense in the Local Seasonings Aisle at the local Rouse’s.
>have gotten much better in the last six months or so

Are you sure it is 6 months and not 6 weeks, as in after Angela Ahrendts left.
Failed all of them. I totally agree with what the author is writing. Don’t presume anything but measure. I also tend to code in a way that it’s not necessary to know all the intricacies. Its not as clever as many like and often makes for longer code but is usually easier to read.
I cannot elaborate. I once interviewed one of the Boeing design team execs who told me about the book and its key role in designing for human perception but that is all I know. I wish I knew more.
OK you tricked me. But the test would have been better if the answer was "undefined behavior" instead of "I don't know".
It seems that "political correctness" is only applied to liberal causes. Conservatives have their own politically sacred issues, yet there is no pejorative use of "PC" about these issues. Why is that?

For example, I find flag fetishism and reciting the pledge of allegiance to be creepy. Wearing flag lapel pins is an effortless show of patriotism. Ascribing heroism to every member of the US armed forces is ridiculous. It would be political suicide for liberal politicians to express such opinions, but the reverse is certainly not true -- conservatives get bonus points from their base for dismissing liberal causes as being PC posturing.
I would love to know this as well. It sounds high but we have no baseline to compare it against - for all we know it could be a massive improvement.
Pacific Crest Trail, 2019
I wonder how many C programmers have experience with writing multi platform/compiler code. I have done a lot of C and C++ but never had to port it so I would not be surprised if I had made a ton of mistakes.
Really depressing. Between work, long commute, gym, and part-time grad school, I have 18 free hours a week out of 168. Makes me wonder what the hell I am doing when I have other hobbies that I would love to be pursuing. Most of the time I simply don't have the mental energy to pursue much of anything in my 18 free hours. Sometimes I just need to turn my brain off.

I find myself to lash out in weird ways when I am particularly stressed. For example, I am much more likely to spend a lot of money on something that seems like it has the potential to make me happy or book a vacation spontaneously. It seems like keeping my head on straight requires so much willpower that I can't save any for other aspects of my life. Who knew life was hard?
Like a lot of things, I ran out of time to be my own sysadmin. Same reason I have up on ddwrt
In most contexts that's how it is, which is great. But it's going way too far on college campuses, where professors can get crucified on social media and then fired for saying the tiniest "problematic" things.
>Do you have a specific language in mind that offers improvement?

Any language with memory and type safety should comprise as much as possible of the whole system. See the Singularity OS from Microsoft Research, or whatever that Rust OS project is called.

Almost all the major, nicknamed, headline-grabbing RCE bugs in the last two decades are memory or type safety issues in C or C++ code.

Every C or C++ developer claims safe code is possible or even easy in their favorite language, but history has proven them very wrong.
~70 hours free time/week or 10 per day, wohooo...freelancing all the way baby!
I know circuses are pretty much a thing of the past, but the i3 would fit right in at one. I always just figured that people who buy EVs really want everyone else to know it.
'Scuse me? As much as I like AMD more, Intel is pretty competent:

They design motherboards, and share their designs with their OEM's- much like reference GPU's.

They (via acquisition) have some of the better wired NIC's on the market (their features for sure beat Realtek's, and are more or less on par with Mellanox's.)

[Intel doesn't] have a clue about how to design circuits or software.

Them managing to even produce a single CPU and have it work would disprove that.
Sure, I mean they float, right?
Lmao no doubt the chongs started stealing shit around that time.
I had a 2010 Prius with the solar roof. It does work, but it just reduced the temperature from unbearable to quite hot, it did not make it cool. It's somewhat nice to have on very hot days, but is not really a killer feature.
What if they kept your subscription at the same price (without ads), and offered a new ad-supported tier for X% off?
Don't stop there. Think about why women are less likely to be interested in it. Think why that might be true in the culture you come from but is not true in other countries. Don't stop at proximate causes and try to find root causes.
Bicameralism seemed a lot sillier to me before I found out I had aphantasia (lack of a mind's eye), and most people see imaginary images while awake. Hearing the voices of imaginary gods doesn't seem all the different from seeing false images.
This is false. When BT was privatized, the UK government sold the shares and collected the proceeds. That’s not “socializing the costs” any more than in any other divestiture transaction.

Additionally, these companies went from requiring huge operating subsidies to becoming net contributors to the exchequer through paying taxes: https://www.cps.org.uk/research/the-performance-of-privatisa....

> When the Conservatives came to power in 1979, the major nationalised companies were receiving large sums of taxpayers’ money. NERA’s report reveals that in the year to March 1980, the 33 companies it examined were contributing nothing to the exchequer: in fact they absorbed a total of £483 million between them, including £1,199 million in loan finance. British Steel was one of the worst companies requiring £1,020 million in the financial year 1980/81 on a turnover of just under £3 billion (thereby earning itself a place in the Guinness Book of Records).

> This dismal state of affairs has been reversed. In 1987, the 33 companies examined by NERA contributed £8,374 million to the exchequer. Net contributions have continued at a high level in each of the last eight years.
So replacing "lunatic asylum" with "mental institution" and " Negros" with "African Americans" is Orwellian?
I was specifically addressing the anxiety that people are feeling about "saying the wrong thing" and offending someone, it's certainly not all that needs to be done to end marginalization, but many of the other things such as preventing housing and employment discrimination aren't on individuals to fix, it's on the government to enforce
I think commute time should count two or three times. I sit in the car for 80 minutes a day and I am totally shot in the evening so I get nothing done even if I have time. . On the days I work from home I work the same amount. After work I relax for half an hour and can do things after. Commuting is a real soul killer in my view.
Sad to say I scored perfectly, due to a similar early disillusionment on embedded platforms, and years of pain porting code between 16- and 32-bit architectures when the author thought they knew the size of “int”.
To play with this effect yourself:

1. pull apart an old multi-platter hard drive

2. Take the platters out

The platters are very flat, and they stick together remarkably well without any liquid between the surfaces. Specks of dust will stop them sticking together so well.

Be careful not to breath in any dust (or eat anything!) from the drive, as they do contain some exciting elements.
With right lobbying strategy and targeting lawmakers during campaigns, I have no reason to believe that Amazon cannot influence enough heads in their favor. Are government entities such as FCC are the absolute gatekeepers that we expect them to be? I am highly skeptical. Look how FAA handled Boeing's 737 Max and we ended up with two crashes. A company of Amazon stature and resources can easily influence and overwhelm FCC into giving them green light. For Amazon this is a two fold win; Blue Origin will finally have a purpose, and further domination of Amazon in farthest corners of the world.

Note that this is a big oversimplification- it doesn't apply to gage blocks. Cold welding and similar phenomenon can only truly happen with metallic bonds and very large grain sizes. Non-metallic bonds are structured and require precise orientations and conditions to reform. Metals are still structured -metals have crystal grains- and the microscale structure needs to line up in order to reform. In cold welding, you force that to happen with high pressures.

This doesn't really apply to gage blocks because tool steel has passivated surface oxides and complex crystal structures. There are very few metallic bonds exposed on its surface. It also has very nasty, often needle-like grains. There's no chance that the metal atoms are being attracted to each other. Not to mention that wringing works with ceramic gage blocks as well.

It is probably a complicated combination of effects. Adhesion (intermolecular forces) probably plays a minor effect at small regions where the surfaces are extremely close together. Casimir forces probably have an effect on most of the surface. Small amounts of grease probably form much stronger adhesions by "carrying" the forces between the surface oxides. Vacuum being trapped by grease probably plays a fairly large part in rougher blocks wringing in an atmosphere. Adhesion and Casimir forces are not well understood.
> In Netherlands, a major chain in Amsterdam would only take cash or a Dutch credit card. Visa/Mastercard from elsewhere were not accepted forms of payment.

Same experience just recently -- Albert Heijn. You'll find this grocery story every 50 meters in a major city like Amsterdam. No credit cards. It was pretty odd to me as a Canadian.
My score is 3/5.

One immediate redflag I have noticed is using "int", "char", "short" as if they have a definite size. They don't. C standard only guarantees a minimum size. For example, many PDPs are 36-bit. Assuming the size of a variable is a common practice nowadays, but at least one should use uint8_t, int32_t, etc. from stdint.h.

But I was still tricked, it should be obvious in hindsight, 12 years of schooling led me to think: If the author was asking these questions, at least one or two questions must be answerable (even if it's technically incorrect, but you'd better to guess the original intention of a question). So I still tried to guess and got two wrong answers... Get to be careful next time...
Being able to trade milliseconds faster is about as pure zero-sum as you can get. The comparison isn't versus having no stock markets at all.
Tangential question, but what Lisp is the most promising one to invest time on right now?

Common Lisp still has some activity, mainly coming from SBCL, but is a bit stagnant. It has a fantastic literature and many mature implementations.

Scheme is great, but a bit too fragmented. Racket seems to be gaining some momentum. The merge with Chez may be the tipping point to attract a critical mass of developers.

Clojure has many interesting modern ideas, but I feel being so tied to Java and the JVM has hurt a bit in the long run.

I miss a bit of innovation in the typed lisp area, like e.g. Qi or Shen which never took off. Carp [1] looks nice.

Yep, admit I was a little taken aback after the drilled holes explanation. This seems correct, as no practically priced cymbal could be so precisely made.
I scored perfectly. I've been programming in C since 1989, on various platforms (started with the Amiga, then VAX/VMS, Linux x86, and various embedded systems.)
That's from January 2015 - much has changed since then.
At the end of the test, the author talks about automation programming for a nuclear power plant. I don’t think I could ever sleep the same at night after writing something like that.
Sure, why not? Cheaper stuff, from another angle, means you can work fewer hours to achieve the same lifestyle. And that's pretty good!
Yeah I'm in two minds about obtaining the precise street address.

On the one hand there is actually nothing to stop you just entering a street name and omitting your residence number - I think it will still setup the notice board and email group exactly the same.

And there is nothing to stop anyone from putting in some other street number than their own. There's no easy way to validate the correctness of that info - and it would be invasive to try.

There might be something useful that can be done with the street number though, I'm not sure. The flexibility of the geographic boundary is basically as general as the google maps API search. So it can be very broad.

As far as yoga groups or parents school groups etc are concerned, it seems like that domain is covered by FB...

I'm keen on fostering better street communities. Very light connections. Making it possible to do things like borrowing tools from each other, or creating a little veggie garden for the street, encouraging the sharing of resources with your neighbours. There's so much overlap and waste with everything...

And e.g. you probably wouldn't lend your spade to some random in your neighbourhood, but maybe lending it to the guy who lives across the road, is less of a big deal. After all - you know where he lives.

Love what you said about having a feel good story, and creating an example notice board page. Thank you will do!
I failed the first couple, rapidly getting into I don't know.

My bro-in-law had one and liked it, then moved to Nebraska. First snowfall they had to get rid of it - it was terrible on anything slippery.
I'm not banking on any language shift at the moment but could see a plausible case in the past for Ada and maybe now Rust after some more years of maturity both down to the metal. But both of these suffer from some awkwardness around the toolchain for integration into a traditional BSD right now, at least Rust may overcome that in time.

syskaller is in use by the major BSDs and stricter compilers and other static analysis tools have been a far bigger impact IMHO than the OpenBSD style mitigations. I would like to actually see some kind of case studies where OpenBSD mitigations have protected a user where they'd have been let down by say Linux or FreeBSD or OpenBSD without them.

I think a less snake oil approach to security is done by the seL4 folks, the difference in approach makes the *nix security mitigation people somewhat cringe worthy.
5/5 - but I came to Hacker News to procrastinate from the C parser I've been writing.

Really? It seems unlikely to find ones flat enough in such a non-precision environment to exhibit the same behavior. Maybe they were flat enough and cupped so that you could create a slight vacuum like you can with the palms of your hands? Would love a picture if you could get one.
240 V 50 A dryer outlets are said to work pretty well, if you happen to own a house. Normal 15 A appliance outlets barely work (Tesla says one hour per three miles!) and no apartment building has ever offered me a parking space that had one.

I wouldn't buy a pure-electric until nearly all apartments have charging, and that work has barely started.
Honestly, I will ditch it anyway.

It's the same with the loch ness monster, the famous 'surgeon's photo' has long since been admitted as a fake, yet people still believe it to be proof. Granted, as with bigfoot that's not the ONLY ever sighting, but it's the one that cements the story as believable to most people.
Right, but aren't now. Progress is being made, fortunately mountain bikers (and their organizations) are much more open to progress.
That argument can apply to any improvement in efficiency of a process.

Admittedly any contribution of HFT to economic success (other than that of the traders themselves, of course) is probably fairly marginal, but more efficient markets are probably a good thing.
> Don’t presume anything but measure.

I think that's exactly the wrong takeaway here. Most of these have a well-defined result on a given platform (host + abi). You can measure that result. But it'll be different on a different platform. And the others don't have a well-defined result — a real-world compiler will produce a result, and you can measure that, but it might be different tomorrow. Unless you know the difference between platform-specific behavior and undefined behavior, you don't know which ones to avoid.
Your understanding is correct, fly ash can be used as a substitute for portland cement. It's apparently chemically similar to how the Romans used to use volcanic ash in their concrete mixes. A lot of cement sold these days is a mixture of fly ash and portland cement.

My impression is that fly ash involves the production of more CO2 than burning coal to produce an equivalent amount of portland cement, but it's worth it when you're burning coal anyway and fly ash is basically free as a byproduct. So in practice it essentially offsets CO2 emissions from burning coal, but only partially.

That's just the impression I've gotten though, I don't have any numbers for any of it.

If you are not aware, I recommend you look up the design process for the space shuttle. It is a perfect example of engineering taking a backseat to politics.

TL;DR version:

The original design of the space shuttle was vastly smaller and simpler, but during the cold war the only way you could get something funded was to have a military dual use. So the Department of Defense offered NASA funding so long as they redesign the entire space shuttle to be able to capture and return Soviet satellites to the US -- a task that it never performed -- which required the design to be massively compromised.
