That hypothesis should be demonstrable.

With the small numbers talked about it’s probably just a statistical blip combined with these people having a high public profile. As the article notes whilst it’s rare it does happen.

For example in this same period as these footballers I had a heart attack whilst exercising. Whilst at 39 I’m older it’s still very young. I am also pretty fit and have no obvious physical heart problems. So right now the doctors think I just got unlucky. No steroid or drug use on my part either. This was also prior to getting vaccinated and contracting Covid.
So?

My point was that if you don't care about safety, C/C++/ASM have good aspects too.

I can write a program without a single pointer in C, and it will be fast, small, and portable.

Java is used a lot in data science alongside Python. And Javascript also have bindings for Tensorflow and other libs. They are scripting languages able to call C code, by definition they are glue languages.
I heard about that too but I also know that one of those players was definitely not vaccinated (the one at Wigan, if I recall correctly?) so that undermines the link somewhat.

I mean, it could be a coincidental cluster, it could be that footballers are reaching a limit in terms of fitness that we'll now see more of this, it could be… anything. Again, more investigation is needed.

As to the link between increased heart problems, like the doctor in the link I shared, I've previously argued that it could be due to lockdown, things like people staying away from hospitals, getting access to doctors, sitting at home too much etc. I'm also keeping in mind that, as we're always reminded, these type of events occur more due to COVID-19 than the vaccines, so it's possible that the vaccines are producing cardiac problems that the disease would've produced but the vaccine came first.

Basically, I can see a lot of possibilities and want to keep an open mind, and I certainly don't want to get into either of the politically driven sides that have formed around this virus.
How do you feel about the absl containers? Are they also slow for low-latency?

varpi is a very old-school way of writing π (think 100 years ago), the modern letter is, of course, π. Also varsigma is the "final sigma" (ς), not the regular sigma (σ). vartheta also looks funky (θ normally).
“Four and twenty blackbirds baked in pie” is a line from English nursery rhyme. Also two score and ten meaning 50 is not that old. At some point fairly recently English must have changed to the current system. Until the 1960’s there were 12 pence in a shilling and 20 shillings in a British pound sterling (240 pence).
The first funeral I ever attended was the older brother of one of my childhood friends who died suddenly of heart failure in his 20s. He was healthy and athletic, with no known drug habits.

I've seen multiple posts about young adult heart failure being passed around in anti-vax forums. "This never happens! They just got the vaccine!", and all I can do is shake my head. The best part is sometimes people post pictures of a young adult who passed away from heart failure in spring of 2019 and try to blame mRNA vaccines still.
> When it comes to writing code, the number one most important skill is how to keep a tangle of features from collapsing under the weight of its own complexity. I've worked on large telecommunications systems, console games, blogging software, a bunch of personal tools, and very rarely is there some tricky data structure or algorithm that casts a looming shadow over everything else.

Could not agree more. Most programs require appropriate organization. The Venn diagram intersection between puzzle solvers and organizers is pretty small. The last thing an organizer wants to see in the code is unneeded cleverness. That is, cleverness that is only there because the author is a bored puzzle solver.

The introduction to the article needs more context. I don’t understand why it exists, who cares about it and who would believe that.
HFT needn’t mean low latency is required but of course the two tend to be related.

If trivial allocations might cost you a microsecond then you can’t allocate at all on a latency-sensitive critical path and should probably get a better allocator. Also, be wary of power-of-two sized things because if they are aligned they are likely to have poor cache performance (too many things compete for the same set of cache lines).

> each clock cycle is still the worse-case time for all steps in the pipeline

The pipeline takes variable count of clocks to complete an instruction. The number depends on the instruction, input data of the instruction, and quite a few other things. In some exotic cases it even depends on power state, e.g. some Intel CPUs took ~20k cycles to power on their AVX pieces, during that window AVX instructions are much slower.

If for any reason the pipeline is unable to deliver the result by the end of the clock, CPUs don’t delay the clock, they continue running the clock. You simply gonna get the result on some later clock cycle.

I think windowing and bucketing are a useful conceptual model for understanding the precision of the encoding space. I understand how FP values work in practice but this article really hits the nail on it's head when explaining the less tangible aspects of FP encoding.
Have you tried cargo-vendor for managing all the dependencies?
This explanation does not make sense to me, which is probably due to my lack of understanding, but perhaps you can expand on this:

> about 30-45 accounts _which had stake at that time

The this is stated makes it sound difficult. But if this is false history presented by a malicious node, surely they could make up anything, as it the data does not need to line up with any official history at any point. (Without a trusted party, no history line is really offical anyway, is't it?). Constructing a history with 30 accounts with stake at any given point in time isn't any harder or easier than constructing 3 or 3000.

I believe we're not saying opposing points of view. What I'm arguing for is moving corporate law on chain, mostly regulating relationships between shareholders, and keep everything else real world. In Europe for instance it's quite absurd how much bureaucracy you have the cope with to create operating entities in different countries within the same economic space. Everything else can stay the same - penal law in particular. It's a very fine line but I believe it can make sense in some instances
>My discussion about phantom braking is when autopilot is on...trivially easy to turn off

Seems odd to have to disable features based, not on one's preferences, but on one's tolerance for errors, especially given that--even without full autopilot enabled--some of those features would be considered active safety features.

"This feature can help keep you safe, but it also might make mistakes, so tap here if you don't want to roll the dice".

In any case, my main point was around the fact that people have such a wide tolerance for errors. I think it's interesting and I was suggesting that it's something more intrinsic to the individual, which I believe is one reason people's opinions on Tesla seem to be "polarized". You'll probably never see those errors as a big deal. I'll probably never see them as not a big deal.

>I don’t know how many folks you know in real life who actually drive teslas, but the narrative that you describe...

I know a few. I don't really talk about their cars with them. And, in any case, it seems like their experiences would vary based on which models/years/updates they've experienced, which features they use and, of course, their tolerance for errors and other problems.

In general, I never really considered that I have a Tesla "narrative". If I owned one I might care enough to have one. My only concern is that the company is too cavalier about safety issues, to include the name "Autopilot" itself, which seems to want the cachet of what the term implies without the responsibility that comes with people trusting it.

Last time I called a locksmith to let me into my house (me losing my keys and locking myself out is a somewhat frequent occurrence) he didn’t even bother trying to pick it. Just took a few plastic wedges and used a rubber mallet to hammer them in between the door and the frame and the whole thing popped open. Took maybe 5 seconds.

Of course, you can reinforce your door frame and this doesn’t work. But the next locksmith (like I said, regular occurrence) used a bump key to pick it and was in just as fast.

Needless to say, I don’t trust door locks anymore.

PoB: Proof of Bullshit
When I go shopping in shop with FFP2 mask mandate, about 10% of people wear the mask properly. The rest have gaping holes between their faces and masks.

BTW that includes me, as I see no point in the benefit/discomfort ratio, being vaccinated and moderately young. Light incidental exposure may even help boost the immune response, though I will reevaluate once B1.1.529 is common.

IMO, those who want to, can¹ wear masks properly and then it's very effective (see infections in covid hospital personnel), but masks tend to be uncomfortable, so most people don't.

¹ some can't, but then maybe we also shouldn't be driving so we don't kill people that way
No, most of those are "actually spurious" in the sense of the two time series having nothing to do with each other. A lot of them are pretty short series as well, so it's easy for them to be correlated.

What we are looking at is Simpson's Paradox, where the true causal relationship is obscured by information that isn't obvious from the plot.

Now before you correlation != causation, there is actually a causation here that you can access with statistics.
I can say that struggle is not universal: I learned German as an adult, and don't struggle with writing down numbers I hear spoken. In fact, I'd never even thought about it being hard.

Every once in a while I say a number backwards (like once or twice a year), but I usually catch myself half-way after spitting it out.
While I very much appreciate and respect author's detailed analysis, I am still not 100% convinced without a corresponding benchmark result. If it's really O(log n) vs O(1), it should be very easy to verify in some micro-benchmark.

Instead of that, the author mentioned that:

> The tests that I did run, initially the libstdc++ and the libc++ versions have roughly the same performance, but the performance diverges after a number of insertions somewhere between 6,400 and 12,800. After that the runtime of the libc++ version is roughly 2-3 times that of the libstdc++ version. (...) the outcomes of which depend on the compiler version anyway.

This does not seem right.

I think many English speakers would admit 11 through 19 are a bit of a weird case. It would probably make more sense if we went ten, oney-one, oney-two, etc. I imagine most English people subconsciously treat 13-19 as individually named as 0-12 are, rather than comprehending them as a composition of two numbers as 20-99 are.

That said, based on the other commenters here, the mixed endian nature of German counting seems very strange to me, being able to generally read numbers the same way they're serialised on paper seems useful.
Glass break sensors are almost never installed in residential homes; motion detectors are a lot cheaper, easier to install and more effective since a lot of attacks against windows don’t involve breaking the glass.
If you could get me the sources you're drawing these conclusions from. Your summary isn't exactly helpful.
> I don't retain arbitrary facts.

I still fail to understand what is arbitrary in scientific notation. The designers almost certainly didn't think in terms of windows when creating the data types, they probably thought about the mantissa and exponent the way it's usually explained, and maybe about information density (entropy per bit) when comparing with other possibilities.

Anyway, if it helps, great. Different explanations are always welcome. But this one is post-fact.
I was wondering about that bit actually.

Suppose I'm a new node and want to verify the blockchain. How do I verify that each block was mined with the correct difficulty?

I'd need some record about the actual real-world timestamps for each block. Then I could say something like "duration between block x and block x+1 was > 10 min, so the down-adjustment in block x+5 is justified".

But if those timestamps were stored on-chain, an attacker could simply lie about them and keep difficulty artificially low on its alternative chain.

On the other hand, if we had some un-forgeable record of block timestamps, wouldn't this solve the double-spend problem all on its own? Would we even need PoW at this point?

Edit:

Ok, sibling comment seems to suggest bitcoin has solved this problem differently: https://news.ycombinator.com/item?id=29368166

I didn't know about "Unwritten Laws of Engineering" - skimming through some of it, this is an excellent book and I wish I knew about it before.

I was fortunate enough to be around senior engineers who took upon themselves to mentor junior engineers like myself. Now that I'm in their shoes, I find that the engineering landscape has changed quite a lot (especially in software) and often find that junior engineers don't see themselves needing to be mentored and sometimes even offended by recommendations.

I think some of this can be seen in this thread as well - some are commenting about how bad these recommendations are, and some even about the general practice of recommending books (how dare you!).

Given that the OP is just talking about books that he felt changed "his" career, I think it's really not something to be challenged and disagreed in such manners.
Easy, you put the transaction in the previous block. So the miner can only mine a block if they have already made the expenditure.
No, they're not showing dislikes to creators on their own videos. The rest still gets to see dislikes.

At least, that was my takeaway.
The system is actually based on scores, 20, which is called a snes in older Danish, so halvtreds is short for halv tredje snes, the half third score, and 60 is tres, short for tre snese, i.e. three scores and so on. So for the tens between 50 and 90, we count scores, and if it's not a whole number of scores, we name it the half of the score that we are into. It's also preserved in a very infrequently used variant word for 80, firsindstyve, which is just 4 score, more explicitly (tyve is the modern word for twenty). In conclusion: Yes, the Danish number system is relatively silly.
You just need a technology that only works across spaces no larger than a couple feet.
I think there is a misunderstanding about security by obscurity. What is bad is hiding defects instead of addressing the problem. It does not mean you should reveal everything! I find it well explained in the video.

For example, if you don't tell people what kind of lock you are using to secure your stuff, this is a form of security by obscurity, but it is not a bad thing. Even if your lock is one of the best, if an attacker knows what it is, he will be better prepared. I think no one who cares about security will tell you things that you don't need to know, it is called OPSEC, I believe.

What is bad is when you realize that your lock is weak, instead of trying to fix it, you try to hide the weakness. And that's the idea that LPL criticizes in his talk.

Hiding his identity is most likely not his only defense against the craziness of the internet. From his videos, we know that he has guns, and who knows what he secures his house with. He is most likely prepared to deal with the consequences of an identity leak, but that doesn't mean he wants it to happen. That's defense in depth, an other important part of security.

I find this to be true even in cases when you have large projects. Sometimes the scale of the project will necessitate adding 'extra complexity' to a specific set of core modules but this is only in order to reduce the complexity of other peripheral modules. IMO, you should never add extra lines of code to a module beyond what is immediately necessary unless it allows you to reduce even more lines of code in other parts of the code.
This is a reference to this post:

I had a discussion about it at work because my teammate is vocal about the alleged harm that vaccines cause and is no stranger to confirmation bias.

Shame that they lumped so many people into the same group, because if you look closer at the data for e.g. England:

https://coronavirus.data.gov.uk/details/vaccinations?areaTyp...

There's a strong correlation between age and vaccine intake, because older people were given priority.

The difference in intake among the age groups is as high as 50 percentage points.
That's extremely telling to consider The Project as 'left wing'. Basically everybody on the left hates The Project, it's definitely not 'left wing' unless you are looking from a very right wing perspective.

The ABC has shifted right massively lately from being centre left recently - personalities like David Speers and Leigh Sales basically becoming Government spruikers, Insiders and Q&A becoming infested with a lot of "false balance" (i.e. get a right-wing personality with no qualifications on to debate this PhD climate scientist), etc.

I've worked in many HFT shops and that's not my experience.
A lot of those firms have poor C++ code though, but std::deque was typically used in the better ones.

It's not one allocation per element, as said previously it's a segmented vector. It works similarly to virtual memory: fixed-size segments are allocated for contiguous storage, while another parent array points to the segments. So appending/prepending either needs to append/prepend to the last/first segment or to allocate a new segment if full, which is what makes those operations more efficient than on a vector. Yes there is indirection, that's what segmented means. You also get stability of the memory location which is important for many data structures.
The article even tells you how big the segments are in the two implementations being looked at.

Going back to HFT, a similar data structure that's definitely heavily used there is a pool, which has a configurable segment size (potentially variable) and doesn't have order, enabling faster deallocation with a freelist.
